This improves the storage density and creates more efficient flow patterns that facilitate increased annual output with the same or fewer resources. The efficiencies are normalized each year creating an annual budget deflation rate, which Crescent has delivered for 10 straight years. Highlights of this "high trust" partnership are total cost transparency, bi-weekly quality meetings, Monthly SLA reviews and joint sponsored Black Belt projects.
Embedded contract packaging operations demand efficient flow. The focus on improving the flow of materials thru the facility by applying lean sigma projects has delivered year over year budget deflation and guaranteed annual cost savings. Highlights of this client relationship are total cost transparency, monthly SLA reviews and an integrated management approach for procurement and planning.
Dedicated Client operations allow for focused improvement projects. Through the application of continuous improvement strategies and lean principals, Crescent achieved greater production efficiency and improved pallet flows. Highlights of this relationship include weekly-integrated planning sessions with the client, weekly performance reporting, and monthly SLA reviews.


With the holiday season approaching, those looking for a new home will feel drawn to the three-bedroom single family home located at 61 Crestview Dr., Holden.
The nine-room house is perfect for entertaining, said real estate agent Kitty Bradshaw, of Re/Max Vision, 1 W. Boylston St., Worcester. There are large areas to get together and areas for separate activities.
The home is 2,000 square feet and rests on more than 16,500 square feet of land. The house has a new roof, new siding and new windows. It has easy access to Route 290 in one direction and Dawson School and the recreation area in the other.
"It amazes me it hasn't sold," said Bradshaw. "It offers the location. It offers the condition. It offers the size."
The price on the home was just reduced to $269,900 after four months on the market. and the owner has already moved out so the future owner could be entertaining in the home by Christmas.
The home was built in 1965 and is a split-level design with lots of options for space. The lower level offers a space for a family room, a game room or a "man cave," said Bradshaw. The home also has office space on the lower level.
The main level of the house offers formal living and dining rooms in addition to a heated sunroom with a dining area overlooking the deck, and gardens that the new owners can enjoy all winter long.
Outside, a single car garage adds to the home's other off street parking.
The home is surrounded by a well manicured lawn, and a garden full of perennials. So once spring arrives, the new owners will be able to enjoy a beautiful and low maintenance yard.

GeoArabia (2015) 20 (2): 19-74.
Twenty taxa are described from the Cretaceous of Oman (Adam Foothills). The genera Puzosia, Placenticeras, Cunningtoniceras, Nigericeras, Metoicoceras, Rubroceras and Hoplitoides and the subgenus C. (Gentoniceras) are recorded for the first time from the Arabian Peninsula. Based on the ammonite ranges, a sequence of nine bioevents of the Albian–Turonian is correlated within the zonation, and some markers allow correlations at a larger scale, at least along the southern Neo-Tethys margin. The ammonite data give new constraints for the correlations of the lithological units along the Adam Foothills West-East transect and they question the definition of the lithostratigraphic units within the Natih Formation, especially the Natih A and B members. From a paleogeographic point of view Oman is a landmark for the distribution of the ammonites between the western Neo-Tethys (Europe, North Africa, Middle East) and the eastern Neo-Tethys (Africa, Madagascar and India).
The present study analyzes the taxonomy and the temporal and spatial distribution of Cretaceous ammonites collected during two missions in the mountains of Oman in 2009 and 2012. This paper follows an important related previous work by Kennedy and Simmons (1991) that has been achieved on the ammonites of Oman. Some biostratigraphic and paleogeographic results have already been discussed in a synthesis of the Cenomanian–Turonian faunas along the southern Neo-Tethys margin from Morocco to Oman (Meister and Piuz, 2013). The microfauna is the object of separate papers (Piuz and Meister, 2013; Piuz et al., 2014). These two fossil groups add greatly to the understanding of the biostratigraphy and paleoecology of the Albian–Turonian deposits of this region.
The mountains of Oman constitute an arcuate range situated on the northeastern margin of the Arabian Peninsula as a result of a compressional up-folding (Figure 1). They may be considered as having been a major mountain range since the Oligocene–Miocene. They are composed of a set of nappes overlying autochthonous and parautochthonous rocks. The mid-Cretaceous deposits have an economic importance and consequently are the subject of extensive studies for geological mapping and petroleum exploration. During the Mesozoic, the eastern part of the Arabian Plate was covered by extensive carbonate platforms globally interpretated as shallow-water areas. The study of Droste and Van Steenwinkel (2004, their figure 15) reveals that the carbonate platform of Oman shows a rather complex structure as illustrated in their geological model.
The Adam Foothills form isolated relative autochthonous outcrops in the southern foreland of Al Jabal al-Akhdar. They constitute a series in relay of abraded anticlines, mainly composed of Cretaceous shelf carbonates. From east to west these are Jabal Madar, Jabal Madmar, Jabal Khaydalah, Jabal Salakh, Jabal Nadah and Jabal Fitri. They represent a transect of about 127 km where several fossiliferous localities have been studied (the distance between each of the localities is given in figure 2 of Piuz et al. (2014).
The geological history of Oman has been extensively discussed by several authors, among them Glennie et al. (1974), Hughes Clarke (1988), Rabu (1987), Robertson et al. (1990), Pillevuit (1993), Rabu et al. (1993), Glennie (1995), Le Métour et al. (1995), Sharland et al. (2001), Droste and Van Steenwinkel (2004), Simmons et al. (2007). For detailled geology, the reader is referred to these papers.
The fossiliferous sediments studied here belong to the Wasia Group, part of the Hajar Supergroup, which is well represented in the northern and eastern Arabian Peninsula. Glennie et al. (1974) synthesized in a precise manner the different lithologic units of the Wasia Group, and subsequently several works have provided greater detail for these units including Simmons and Hart (1987), Hughes Clarke (1988), Smith et al. (1990), Philip et al. (1995), van Buchem et al. (1996, 2011), Homewood et al. (2008).
About 150 specimens of more-or-less well-preserved ammonites have been collected from the Nahr Umr Formation (Albian) and from the Natih Formation covering a period from the Albian to the early Turonian (Appendix). This period corresponds to a series of marine transgressions associated with eustasy (sea-level rise) and tectonic influences (subsidence) that led to the establishment of a wide carbonate platform with intrashelf basins.
The Natih Formation mainly consists of shallow-water, muddy limestone with local rudist occurrences, and intraplatform basin organic-rich calcareous shale. Several disconformities (hard-grounds) punctuate that formation and are commonly used for correlations (e.g. van Buchem et al., 1996, 2002, 2011; Homewood et al., 2008). The Natih Formation was subdivided into seven informal lithostratigraphic units (a to g from top to base) by petroleum geologists (Hughes Clarke, 1988; Scott, 1990). Herein these subdivisions are labelled A to G (as in many previous publications), but should be taken with reservation due to their lack of rock outcrop formal description, and regarding their variation of lithology and thickness along an East-West transect (from Jabal Madar to Jabal Fitri, see Piuz et al., 2014). New and significant constraints for correlations are given by the ammonite data exposed below.
The ammonites of the Wasia Group were studied for the first time in 1991 by Kennedy and Simmons. van Buchem et al. (2011) also listed a set of ammonites. Our study completes these works in describing additional taxa and in ageing the Natih Formation more precisely (Figures 2 to 8). It adds precision to the regional biostratigraphical framework and correlates nine bioevents with the zonation (see Meister and Piuz, 2013).

Discussion: One group of nautilids having a smooth conch and a micro-umbilicus has been found in the Natih Formation. It is characterized by a compressed subogival whorl section associated with a sinuous to falciform suture line.
Age and distribution: This taxon is associated with Neolobites that characterizes the lower part of the late Cenomanian. This association is well represented on the southern Neo-Tethys margin from Morocco to Oman.
Type species:Ammonites planulatus J. de C. Sowerby, 1827.
Discussion: Badly preserved, this rather evolute form shows a fine ribbing on the outer part crossing the venter and periodic constrictions. Its whorl section is suboval slightly compressed. This form corresponds to the Puzosia group taken in a wide sense. A second larger specimen has strong constrictions and ribbing.
Age and distribution:Puzosia has a worldwide distribution and in Oman this form has a probable middle late Cenomanian age (M. geslinianum Zone).
Type species:Ammonites placentaDeKay, 1828, p. 278, subsequent designation by Meek, 1876, p. 462.
Age: Late Albian–Maastrichtian. Taken in account the interpretation of Cooper and Owen (2011) the earliest Placenticeras are rather of Cenomanian age.
cf. 1989 Placenticeras kaffrarium Etheridge.- Klinger and Kennedy, p. 268, only fig. 23C, D, 42, 43A, B, 44, 45A, B.
Discussion: The bad preservation of our specimens does not allow a precise determination. They are characterized by a (sub)oxycone coiling, smooth whorls, elliptic strongly compressed whorl section and a complex suture line. The incision of the saddles and lobes differentiates it from the subceratitic suture lines of the Engonoceratidae (Neolobites and Metengonoceras) of the same age (see Klinger and Kennedy, 1989, p. 364). This morphological habitus corresponds well to Placenticeras and especially to Placenticeras kaffrarium Etheridge of type 1 in Klinger and Kennedy (1989) and with P. cumminsi Cragin, a contemporary species. The species P. kaffrarium Etheridge is considered by Klinger and Kennedy (1989) in wide sense, with a very large intraspecific variability. Our specimens are only distinguishable from P. kaffrarium Etheridge sensu Klinger and Kennedy by the venter already pinched rounded in the inner-intermediate whorls and by a smaller umbilicus. Our specimens are more peramorphic for these characters in comparison with the illustration on p. 298, fig. 45B in Klinger and Kennedy (1989). If P. cumminsi Cragin also has large variability, it differs with a wider umbilicus and preserves an ornamentation in all the ontogenetic stages.
Due to the preservation, we put our specimens in affinis with Placenticeras kaffrarium Etheridge of type 1 in Klinger and Kennedy (1989) that represents the closest morphology.
Note that the phylogenetic relationships between the primitive Placenticeratidae and the more derived ones is still under discussion (see Cooper and Owen, 2011, p. 339). In the phylogenetic interpretations of Kennedy and Wright (1983, fig. 5) and Klinger and Kennedy (1989, fig. 8), the evolutive relationships show a lack of information during the Cenomanian exactly corresponding to the position of the Omani Placenticeras.
Age and distribution:P. kaffrarium Etheridge is known in the Turonian–Coniacian of South Africa, Madagascar, India ?, Namibia ? and Angola. P. aff. kaffrarium Etheridge type 1 is only recorded from the late Cenomanian (N. juddii Zone) of Oman.
Type species:Ammonites Syriacus von Buch, 1848, p. 20, by original designation.
Remark: See Kennedy et al. (2009), Bulot (2010, p. 169), Latil (2011, p. 347) for the discussion of the family.

Discussion: Two ribbed fragments evoke the morphological habitus of the specimen illustrated by Bulot (2007, fig. 2.3) under the name K. dubertreti Basse, a subinvolute species. The whorls are high and rather compressed for the genus. The whorl section is subtriangular with convergent outer flanks and rounded inner flanks bearing periodic bullae. From the bullae arise two, sometimes three, coarse, blunt, subradiate and spaced ribs; intercalatories are rather developed on the outer flanks. They form a marginal ventro-lateral blunt node. The venter is flat to slightly concave between nodes and low blunt ribs are crossing.
K. gr. uhligi (Choffat) described for Sinai by Geyer et al. (1997, p. 225, fig. 2i) seems to have higher whorls at a similar diameter and a finer and smoother ribbing. Our specimens are more compressed and less coarsely ornamented than K. syriacum (von Buch). K. deserti Mahmoud shows a more rectangular whorl section with a flat, rather wide venter.
Age and distribution: Its age corresponds to the basal middle Albian following Kennedy et al. (2009) and to the lower part of the late Albian (D. cristatum Zone) for Bulot (2007). The species is recorded from Lebanon, Levant, Syria and Oman.

2010 Knemiceras syriacum (von Buch).- Bujtor, p. 6, fig. 4.
Discussion: With a strong ornamentation, specially with blunt ribs and rather massive whorls, our specimen belong to the coarse inflated Knemiceras like K. syriacum (von Buch), K. arambourgi Basse, K. persicum Collignon or K. iraniense (von Buch), four very close species. Their ornamental habitus is similar to that one of K. dubertreti Basse but with a coarser ornamental development. The whorl section is subrectangular with strongly embracing whorls and the umbilicus narrow. Our specimens are close to the Douvillé specimen (1928, pl. 1, fig. 1a–c).
Age and distribution: Early to middle Albian following Kennedy et al. (2009) and lower part of the late Albian (D. cristatum and M. pricei Zones) (see Bulot 2007, p. 52). It is known from Egypt, Lebanon, Levant, Syria and Oman.

Discussion: This well-known species from North Africa and the Middle East has been described in detail by several authors (Kennedy and Juignet, 1981; Meister et al., 1994; Meister and Rhalmi, 2002; Wiese and Schulze, 2005). Most of the Omani Neolobites belong to Neolobites vibrayeanus (Orbigny), a classic species of the southern Neo-Tethys margin. Their variability is low and for the greater part they are characterized by smooth whorls and well developed margino-ventral rows of clavi.
Age and distribution: This species characterizes the lower part of the C. (P.) guerangeri Zone (lowermost late Cenomanian) and is widespread along the southern Neo-Tethys margin (Morocco to Oman, in Europe (France, Spain, Portugal) and South America (Perou, Bolivia and Venezuela). Its repartition is subequatorial (see Meister and Piuz, 2013).

1992 Neolobites fourtaui Pervinquière.- Thomel, pl. 22, fig. 1.
Discussion: Following Kennedy and Juignet (1981, p. 28) we consider N. fourtaui Pervinquière as a separate species, older than N. vibrayeanus (Orbigny). It is characterized by strong elongated umbilical bullae and strong concave, sometimes biplicate ribs on the upper part of the flanks. The suture line is ceratitic, similar to that of N. vibrayeanus (Orbigny) and rather different from Engonoceras (Figure 9). For the Omani specimens, the umbilical size seems wider than in Orbigny's species. N. peroni Hyatt is broader, coarser and has more spaced ribs; the whorl section seems more rectangular (see Dominik, 1985, pl. 14, fig. 7).
Age and distribution: This species is present in the middle Cenomanian (A. rhotomagense Zone following Wiese and Schulze [2005: 941, N. fourtaui Pervinquière is associated with A. rhotomagense (Brongniart)] and in the extreme base of the late Cenomanian (Thomel, 1992, Wiese and Schulze, 2005). It is distributed along the southern Neo-Tethys margin from Tunisia to Oman.
Type species:Ammonites bochumensisSchlüter, 1871 original designation (= Ammonites renevieri Sharpe, 1854).
Remark: The genus Acompsoceras is characterized by a subdiscocone shell shape and shows a large diversity in ornamentation, umbilical size and in whorl section.
Age:Acompsoceras ranges from early Cenomanian (M. mantelli Zone) to middle Cenomanian (M. dixoni Zone).

Discussion: As shown by Wright and Kennedy (1987), the variability of the morphology and the ornamentation of A. renevieri (Sharpe) is wide. A large variability is also observed in the Omani fauna where discocone coarse, massive ornamented forms co-occur with smooth oxycone ones, probably the expression of intraspecific variability. So the smooth forms are close to the specimen illustrated p. 145, fig. 37 (Wright and Kennedy, 1987) whereas the ornamented ones are similar to that of fig. 2, pl. 43 (Wright and Kennedy, 1987) and to the specimen of Thomel (1992, pl. 33, fig. 5).
Two specimens with a diameter of about 150 mm are moderately evolute (umbilicus/diameter = 24%) and are characterized by a weak blunt ribbing, strong umbilico-lateral bullae, small high lateral tubercles and acute ventro-lateral tubercles. The ribs are biplicate from the bullae and end at the ventro-lateral tubercle. The whorl section is suboval with a tabulate smooth venter (Figures 10a, d). Tracks of a siphonal keel are visible. The ornamentation, coarse in the inner whorls, gets weaker on the outer whorls with the loss of the ribbing and of the high lateral tubercles. The ratio whorl width/whorl height = 1.2 at a diameter of 80 mm slightly increases to 1.3 at 135 mm of diameter.
A larger specimen (D = 240 mm) is more involute (U/D = 16%) with smooth, more compressed subelliptical whorls with rather flat flanks. By comparison with the other specimens at the same size, it is already smooth whereas the others still bear umbilico-lateral bullae and ventro-lateral tubercles; moreover their whorls are broader. In term of variability this form corresponds to the peramorphic pole in comparison with the ornamented ones (paedomorphic pole). Some A. renevieri (Sharpe), rather smooth specimens illustrated by Kennedy and Juignet (1993, p. 150, fig. 4, p. 151, fig. 5) or Wright and Kennedy (1987, p. 148, fig. 40) show intermediate morphologies.
Several specimens are also recorded from Jabal Fitri. They are large smooth fragments with part of the body chamber and characterized by high and compressed whorls similar to a specimen of A. renevieri (Sharpe) illustrated by Wright and Kennedy (1987, p. 145, fig. 37) previously known as A. essendiensis (Schlüter).
Some affinities exist with the late Cenomanian Paracompsoceras landisiCobban (1971, pl. 6, pl. 7); but at adult diameters Cobban's species clearly has a wider umbilicus. For the ornamented stage, the bullae are expressed less than in the Omani specimens. The ornamentation is rather different with less expressed bullae and ventro-lateral tubercles. A. sarthense (Guéranger) in Pervinquière (1907, pl. 17, fig. 4, 6) has a similar morphology.
In A. inconstans (Schlüter) the ribbing is stronger and persist longer and the umbilicus is wider (see lectotype in Wright and Kennedy, 1987, p. 149, fig. 41). Moreover a lateral row of tubercles is well developed until the intermediate whorls.
Age and distribution:A. renevieri (Sharpe) ranges from the M. mantelli Zone (early Cenomanian) to the A. rhotomagense Zone (middle Cenomanian) maybe to the ?A. jukesbrownei Zone if we follow Thomel (1992). Indeed for this author A. rhotomagense (Brongniart), A. jukesbrownei Spath and Acompsoceras are in association. Sharpe's species occurs in Europe (France, Germany, UK, Poland, Russia), north and west Africa, Madagascar and Arabian Peninsula (Oman).
Type species:Ammonites cunningtoniSharpe, 1855 by original designation.
Age: Middle Cenomanian to early late Cenomanian.
Discussion: A quite evolute form with lateral spaced and blunt ribs ending in coarse horns. The venter is flat and smooth and the horns are laterally outspread (Figure 10e). A peri-umbilical reinforcement of the rib is also obvious. These characters evoke those of the holotype of C. cunningtoni (Sharpe) (see Wright and Kennedy, 1987, p. 199, fig. 76). Because of the incomplete preservation of our specimens however, we do not give a specific determination.
There are also close morphological convergences with the genus Euomphaloceras, especially for the outer whorls of the large specimens. This genus formerly included C. cunningtoni (Sharpe).
Age and distribution: A cosmopolitan genus of the middle Cenomanian–early late Cenomanian. C. cunningtoni (Sharpe) has a large distribution, but its age precisely corresponds to the A. rhotomagense Zone. The Omani specimens characterize the base of the late Cenomanian (C. (P.) guerangeri Zone).

Discussion: These inflated moderately evolute (planorbicone-platycone) forms are characterized by rather strong ornamentation. The whorl section is subcircular and weakly depressed, varying from the juvenile to the adult stage with a ratio Ww/Wh = 1 to 1.25 (Figures 10f–h). The venter is flat rounded. The embracing whorl overlap is moderate to strong. The ribbing is annular and regular, bearing strong peri-umbilical bullae and ventro-lateral spiny tubercles. One to three ribs originate from the bullae and some intercalatories appear on the third part of the flank. In the inner whorls, the ribs are subradiate slightly flexuous becoming rigider by the adult. A variability in rib-density can be observed [Plate 10, fig. 2 and Plate 11, fig. 2 (Appendix)]. In some specimens, two rows of discrete remaining lateral tubercles, one margino-ventral and another siphonal, are obvious in the inner whorls.
In the adult stage the bullae are still well expressed; but the ornamentation varies in the outer part with a tendency of a smoothing; the tuberculation is reduced and the ventro-lateral tubercles more or less disappear [Plate 11, fig. 1 (Appendix)] but still remain in some specimens [Plate 11, fig. 1 (Appendix)]. The ventral ribbing clearly becomes evanescent [Plate 10, fig. 3 (Appendix)]. Some specimens [Plate 11, fig. 1 (Appendix)] are more inflated with stronger, blunt and spaced ornamentation, expressing a rather wide variability in this species.
The Omani C. (Proeucalycoceras) are closely related to C. (P.) guerangeri (Spath), a rather cosmopolitan species and to C. (P.) canitaurinum (Haas) a species only recorded from the Western Interior (USA). These two contemporary species have a large, partly overlapping variability. In the inner-intermediate whorls Haas' species (see Cobban and Kennedy, 1990, pl. 1, fig. 2–9) is more paedomorphic than C. (P.) guerangeri (Spath) for the persistence of a strong multituberculation (see Wright and Kennedy, 1990, pl. 73, fig. 1, 2, 4). At this ontogenic stage, our specimens better correspond to C. (P.) canitaurinum (Haas) with the rib density and the flexuosity of the ribs but they are distinguishable with the early loss of the multituberculation. At similar size, C. (P.) guerangeri (Spath) has a coarser and more spaced ribbing (see Ahmad et al., 2013, p. 26, fig. 3a–c, 4a-b). At the adult size some of our specimens [Plate 14, fig. 1 (Appendix)] are similar to the holotype of C. (P.) canitaurinum (Haas, 1949, pl. 1, fig. 1, 2), others [Plate 10, fig. 3; Plate 11, fig. 1 (Appendix)] have more inflated and less ornamented whorls closer to the specimen illustrated by Haas (1949, pl. 3, fig. 1, 2). At this size, some C. (P.) guerangeri (Spath) are also close to our specimens (e.g. Reyment and Bengtson, 1986, pl. 9, fig. 6, 7 or Wright and Kennedy, 1990, pl. 70, fig. 1) but this species always keeps a coaser and more spaced ribbing.
C. (P.) besairiei (Collignon) shows more developed ventral tuberculation (ventro-lateral and siphonal) at comparable size. C. (P.) haugi (Pervinquière) is more compressed with stronger spaced ribs.
Although very close to C. (C.) naviculare (Mantell), Haas' species is classically put in the subgenus Proeucalycoceras mainly based on the inner whorls which show a more rounded venter, more depressed and broader whorls and a persisting ribbing in the adult, mainly on the venter. Moreover the ventro-lateral tubercle remains clearly more prominent in C. (Proeucalycoceras) during the ontogeny, and the ventral part remains more flat. The subgenus Gentoniceras clearly differs with a wider umbilicus. Some C. (Newboldiceras) like C. (N.) planecostatum (Kossmat) also shows some affinities with the ribbing.
Age and distribution: This is the index species of the C. (P.) canitaurinum Subzone (lower part of the C. (P) guerangeri Zone), the first subzone of the late Cenomanian. It is recorded from USA (Western Interior) and Oman.
Discussion: Our two C. (Proeucalycoceras) sp. indet. share rather compressed whorls; the second one has only the body chamber preserved. They are characterized by coarse spaced annular ribs. On the flank, the ribs are taut and subradiate with intercalatories at the mid-flank. A reinforcement of the ribs (tubercles) is obvious at the peri-umbilical part and the ribs become rather acute and prominent on the venter. The whorl section with a ratio Ww/Wh of about 0.83 is subrounded with flat parallel flanks. The morphology of the whorls (Figure 10b) and a wider umbilicus distinguish them from C. (P.) guerangeri (Sharpe). The small specimen evokes the C. (P.) haugi (Pervinquière) in Kennedy and Juignet (1994b, p. 479, fig. 6d, e) and is similar to the specimen described by Kennedy and Simmons (1991, pl. 2, fig. H) for Oman.
Age and distribution: Probably the same age than the Neolobites vibrayeanus beds (early late Cenomanian).

aff. 2010 Calycoceras (Gentoniceras) gentoni (Brongniart).- Kennedy and Klinger, p. 9, fig 31, with synonymy.
Discussion: With a more opened umbilicus, slender whorls and regular rather dense ribbing, this form differs from the other Omani Acanthoceratinae. The single specimen is of moderate size and has a half a whorl of the body chamber. It is characterized by annular ribs, a subcircular whorl section with flat flanks and moderately embracing whorl overlap (Figure 10c). The conch is planorbicorne-platycone evolute with a rather open umbilicus (U/D = 33%). The ribbing is subradiate with peri-umbilical bullae sometimes subdivided into two ribs on the flank, and with intercalatories appearing near the base of the flank. At this ontogenetic stage, siphonal and latero- ventral tubercles are already absent. If we follow the dimorphic hypothesis, our form represents the microconch (see Wright and Kennedy, 1990).
The specimen illustrated by Crick (1907) under the name C. (G.) paucinodatum Crick is close to our specimen with its ribbing habitus but has a slightly smaller umbilicus; this 'species' now is included in the C. (G.) gentoni (Brongniart). C. (G.) sarthense (Bayle) shows a similar evolute coiling but differs with its more spaced and coarser ribbing.
Age and distribution: The genus is well represented in Europe, in South Africa, Madagascar, India, Japan, USA, ? Iran and now from the Arabian Peninsula; the species C. (G.) gentoni (Brongniart) occurs in Europe, South Africa, South India, Oman and ? Iran. The species ranges from middle Cenomanian to early late Cenomanian. In Oman, C. (G.) gentoni (Brongniart) is associated with M. geslinianum (Orbigny) and has a younger age (middle late Cenomanian).
Type species:Nigericeras gignouxiSchneegans, 1943, subsequent designation by Reyment, 1955, p. 62.
Remark: Several Omani specimens are attributed to the genus Nigericeras because of a) the ontogeny of the ornamentation [it is well developed in the inner whorls and smoothing or evanescent as in the paedomorphic N. gadeni (Chudeau) or disappears completely as in the peramorphic N. jacqueti Schneegans]; b) the habitus of the suture line; although corroded, the tracks of the suture line show very large shallow saddles and lobes like in Nigericeras (see fig. 2c in Wright et al., 1996, p. 161); c) their platycone evolute coiling with suboval more or less compressed whorl section; d) their close similarities with the Nigericeras described in Niger (Meister et al., 1992, 1994); and e) the morphological variability of our forms is close to that described for Nigericeras by Meister et al. (1992, fig. 15).
There are also some similarities with Vascoceras like V. cauvini Chudeau and there are some morphological convergences with Paracompsoceras Cobban, a genus of the middle (or late for Wright et al., 1996) Cenomanian that shows a similar ontogeny with the loss of the ornamentation relatively early during growth, especially the specimen illustrated by Kennedy et al. (1988, p. 39, fig. 2c, e). Nevertheless the ornamentation persists longer in Paracompsoceras. Moreover Cobban's genus shows narrower and deeper suture lines.
The convergences with V. cauvini Chudeau mainly rest on smooth evolute adult forms like those in Meister et al. (1992, pl. 6, fig. 1). A strong ornamentation in the inner whorls and the suture line habitus distinguish the Nigericeras group (Meister et al., 1992, pl. 3, fig. 1).
The Omani forms come from a rich level in Jabal Fitri and with rare specimens from Jabal Salakh.

2012 Nigericeras gadeni (Chudeau).- Meister and Abdallah, pl. 2, fig. 1, 2; pl. 3, fig 1; pl. 12, fig 9, with synonymy.
Discussion:Nigericeras is considered in the very wide sense, and the Omani specimens correspond well to the concept discussed in detail by Meister et al. (1992, fig. 13). They are close to the N. gadeni (Chudeau) characterized by a morphological habitus somewhere between the strong ornamented N. scotti Cobban and the smooth forms like N. jacqueti Schneegans and N. jacqueti involutus Meister et al.
The inner-intermediate whorls are characterized by strong umbilical bullae extending in ribs that diminish in intensity on the upper part of the flank. In rare cases, ribs crossing the venter are obvious at small diameters. In adults, some tracks of ornamentation are still present towards the outer part of the body chamber. One specimen develops rather fine ribs near the aperture [Plate 15, fig. 1 (Appendix)]. The whorl section is suboval, weakly compressed in the inner-intermediate whorls and a little more depressed in the body chamber.
Our specimen also evokes the rather badly preserved Nigericeras from Texas (Kennedy et al., 1989, fig. 9L, M; 11O, P). In N. scotti Cobban the ornamentation persists throughout the ontogeny (see Cobban, 1971, pl. 19, fig. 1–4) and represents the paedomorphic pole in this genus.
Age and distribution:N. gadeni (Chudeau) ranges from the upper part of M. geslinianum Zone to probably the lowermost N. juddii Zone. It is present in Europe, Tukestan, USA, Morocco, Levant, Oman and especially along the Trans-Saharan seaway from Tunisia to Northern Nigeria where its morphological variability is very high.

2012 Nigericeras jacqueti Schneegans.- Meister and Abdallah, pl. 3, fig. 5, 7, with synonymy.
Discussion: Following Meister et al. (1992) these forms represent the platycone involute and smooth morphologies of Nigericeras, compared with N. gadeni (Chudeau). Their whorl sections are suboval slightly more compressed and their umbilicus are narrower.
Age and distribution: It co-occurs with N. gadeni (Chudeau) in the upper part of the M. geslinianum Zone and maybe in the lowermost part of the N. juddii Zone. It is recorded from Tunisia, Niger, Northern Nigeria, in Oman and probably southern France.

2010 Metoicoceras geslinianum (Orbigny).- Nagm et al., p. 482, fig. 8A–C.
Discussion: Our poorly preserved specimens are characterized by an involute coiling (suboxycone form) and high compressed subrectangular whorls with a flat external part. The ribbing is broad, blunt and spaced, well developed on the outer flanks. Primary ribs are slightly prorsiradiate starting from the umbilicus, evanescent on the lower half of the flank and strong on the upper half where they alternate with secondaries. Despite the preservation, one specimen shows small periumbilical bullae. The ventro-lateral edge is marked by a reinforcement of the ribs that become blunt and cross the venter.
Our specimens are close to the M. geslinianum (Orbigny) illustrated by Meister et al. (1992, p. 65, fig. 1, 3).
Age and distribution: A cosmopolitan species and the index species of the M. geslinianum Zone (middle late Cenomanian). Along the southern margin of the Neo-Tethys, this species allows acute correlations from Morocco to Oman, and to Nigeria in the South.
Discussion: Three badly preserved specimens evoke the morphology of the Pseudaspidoceras with their rather evolute coiling with massive whorls, latero-ventral and peri-siphonal tubercles. One of the specimens [Plate 17, fig. 2ab (Appendix)] shows some affinities with some Nigerian P. pseudonodosoides (Choffat) (Zaborski 1990) or with P. tassaraensis Meister, Alzouma, Lang and Mathey from Niger. Another [Plate 16, fig. 2ab (Appendix)] has a narrower umbilicus that evokes rather P. flexuosum Powell-P. barberi Meister group.
This genus was already recorded from Jabal Salakh by Kennedy and Simmons (1991, pl. 1, fig. C and pl. 4, fig. A, B).
Age and distribution: A rather cosmopolitan genus ranging from the late Cenomanian (N. juddii Zone or maybe even M. geslinianum Zone) to early Turonian (W. coloradoense Zone).
Type species:Rubroceras alatumCobban, Hook and Kennedy, 1989 by original designation.

2012 Rubroceras sp. Meister and Abdallah, pl. 4, fig. 11; pl. 10, fig. 2, 6, 8; pl. 11, fig. 2.
Discussion: A weakly depressed whorl section with strongly embracing whorl overlap, a coarse ornamentation and a subdiscocone shell shape (type 8–9 in Meister and Piuz, 2013, fig. 13) characterize this specimen. The ornamentation is represented by coarse peri-umbilical nodes, blunt lateral subradiate ribs crossing the venter and periodically alternating with weaker ribs.
The Omani Rubroceras is distinguishable from R. burroense Cobban, Hook and Kennedy s.s. by the more compressed whorls, On the other hand it is close to the Tunisian specimens, having a rather open umbilicus. It is especially close to the coarse blunt ornamented Rubroceras sp. of Meister and Abdallah (2012).
Our specimen also evokes the Paramammites sp. of Kennedy and Simmons (1991), but that has a more open umbilicus.
Age and distribution: This species characterizes the N. juddii Zone and is known in New Mexico (USA), Tunisia, Oman and maybe in Nigeria and Ibericas (Spain). Another Rubroceras, R. alatum Cobban, Hook and Kennedy is recorded from Sinai and Portugal as well as the USA.

Discussion: This specimen is characterized by strong ornamentation on the phragmocone mainly on the outer part of the whorl. There is an alternation of blunt ribs starting from the base of the flanks with some intercalatories appearing at the mid flank and crossing the venter. The coiling is planorbicone-platycone and the whorl section is suboval, weakly depressed and with a moderately embracing whorl overlap.
The body chamber is smooth (preservation?) or similar to the variety semiglabra of Furon (1935, pl. 4, fig. 3). Our specimen corresponds well to the ornamentation of V. cauvini Chudeau s.s. (see Chudeau, 1909 or Furon, 1935) and to the wide interpretation of this species by Meister et al. (1992, p. 76, fig. 17).
Age and distribution: This species (sensu stricto) is known in Nigeria, Niger, Algeria, Egypt, Levant, Oman, and possibly in Angola and Texas. It indicates the late Cenomanian (M. geslinianum and N. juddii Zones).

Discussion: One specimen with discocone involute smooth shell shape (type 5 in Meister and Piuz, 2013), weakly compressed whorls and very strongly embracing whorl overlap is near the group of V barcoicensis exile Cobban, Kennedy and Hook. Only its narrower umbilicus (U/D = ca. 10%) is distinguishable from the holotype. It is also similar to the small Tunisian specimen (Meister and Abdallah, 2012, pl. 12, fig. 4).
Age and distribution: Known from New Mexico, Tunisia and Oman, this taxon is present in the N. juddii Zone.
Discussion: Under this name we group several badly preserved Vascoceras. Among them, one specimen [Plate 19, fig. 2 (Appendix)] with a rather opened umbilicus and relatively compressed whorls, shows large similarities with the specimen illustrated by Kennedy and Simmons (1991, pl. 5, fig. A, B) under the name Vascoceras durandi (Peron) or with the specimens of Barroso-Barcellina and Goy (2010, pl. 3, fig. A–G). Due to the bad preservation we give only the generic determination.
Another specimen of Salakh [Plate 19, fig. 3 (Appendix)] corresponds to subsphaerocone Vascoceras with small umbilicus. Its habitus evokes several forms like V. kossmati Choffat or to a lesser extend V. proprium (Reyment), V. tectiforme Barber or V. crassum Furon.
The third, [Plate 19, fig. 5 (Appendix)] with its narrow umbilicus and compressed whorls, evokes the V. barcoicensis exile of Cobban, Kennedy and Hook or maybe the broader V. arnesensis Choffat.
Age and distribution: All these form are from the late Cenomanian–? early Turonian of Jabal Salakh.

Discussion: Two fragments of Fagesia are characterized by very broad, less high, subtrapezoidal whorls, a smooth less convex ventral part, narrow flanks ornamented with large tubercles and by a large umbilicus. The smoothing of the ribbing begins to develop at small diameters. This form belongs to the smooth Fagesia that include F. peroni Pervinquière, F. levis Renz, F. fleuryi Pervinquière and F. catinus (Mantell). Our specimens are attributed to the Mantell's species because of their large umbilicus that distinguish this species from all other Fagesia. However, F. fleuryi Pervinquière also seems to have sporadic large ribs at larger sizes.
Age and distribution: According to Kennedy and Simmons (1991) this species characteristic of the lower part of the Turonian. It occurs in Europe (UK, France), in America (USA, Venezuela and ? Mexico) and Arabian Peninsula (Oman).

2009 Fagesia tevesthensis (Peron).- Barroso-Barcenilla and Goy, p. 25, fig. 4(4), 5(1), with synonymy.
Discussion: This rather cadicone form is characterized by a strong ventral ribbing and more or less expressed tubercules on the low part of the 'flank'. The ventral part is convex and the whorl thickness is weak in comparison with the other Fagesia. F. superstes (Kossmat) is broader, massive, more depressed and more coarsely ornamented in ribbing and tubercles. This may represent the expression of a wide intraspecific variability for a F. superstes (Kossmat)-F. tevesthensis (Peron) group.
Age and distribution:F. tevesthensis (Peron) is known from early Turonian (upper part of the W. coloradoense Zone and M. nodosoides Zone). It is recorded from South Europe (France, Portugal, Spain), North Africa (Tunisia, Algeria), Egypt, Levant, Oman and Japan.
Type species:Hoplitoides latesellatus von Koenen, 1898, p. 56, pl. 6, fig. 1–3, subsequent designation by Solger, 1904, p. 127.

Discussion: Typical smooth oxycone form of the early Turonian that belongs to the H. wohltmanni (von Koenen) because of a pinched rounded ventral part, only the beginning of the last whorl shows a narrow tabular venter. This character is longer developed during the ontogeny (paedomorphic) in H. mirabilis Pervinquière or in H. latefundatus Zaborski. H. ingens (von Koenen) has broader whorls.
Age and distribution: Recorded from America (Trinidad, Venezuela, Colombia and USA), western and northern Africa (Nigeria, Cameroon and Tunisia) and Oman, this species indicates the early Turonian (W. coloradoense and M. nodosoides Zones).

Discussion: The Omani specimens range in size from 2 cm to 20 cm. They correspond well to the detailed description given by Wright and Kennedy (1996, p. 357). As demonstrated by these authors, the variability in ornamentation intensity is rather high. The coarse ornamentation is dominant among the Omani specimens, with well-developed and coarse ribs on the upper half part of the exposed whorl face ending in an elongated tubercle nearby the mid-flank. A spiral groove obliterating the ornamentation is situated above a row of rounded tubercles on the lower part of the exposed whorl face and separates them from the overlying row of elongated tubercles. A third row of smaller spirally tubercles just marks the inter whorl junction and is separated from the second row of tubercles by a second groove.
Some of these specimens show a finer, closer ribbing and more tiny tubercles. These forms have superficial affinities with T. scheuchzerianus Bosc (eg. Atabekian, 1985, pl. 31, fig. 7, 10) but the grooves and tubercles are less developed.
T. acutus Passy differs by the more depressed whorls, with only two well expressed rows of tubercles and a less developed ribbing in the upper part of the exposed whorl face.
Age and distribution: A cosmopolitan species rather common in the middle Cenomanian and rarer in the lower part of the late Cenomanian (C. (P.) guerangeri Zone). The Omani fauna belongs to the second period.
A range chart for the Cenomano–Turonian ammonites (Figure 11) adds precision to the biostratigraphical framework proposed for Oman by Meister and Piuz (2013, their figure 6).
The succession of the Albian–Turonian ammonites in the Adam Foothills allows us to propose a set of nine bioevents for this period (Figure 12).
The age of the Knemiceras beds with K. syriacum and K. cf. dubertreti is poorly constrained and still under discussion. Moreover in the recent literature, there is no consensus. Indeed K. syriacum indicates the early–middle Albian for Kennedy et al. (2009), most probably of middle Albian age if we follow Lewy and Raab (1978) and the early late Albian for Bulot (2007). Whereas K. cf. dubertreti corresponds to the basal middle Albian sensuKennedy et al. (2009), and to the base of the late Albian for Bulot (2007) (D. cristatum and M. pricei Zones), respectively hypothesis A and B in Figure 12. For the moment without better local biostratigraphical constraints, we cannot determine the precise age of this fauna: either middle Albian (hypothesis A) or late Albian (hypothesis B).
The association of the long-ranging Acompsoceras renevieri and Neolobites fourtaui indicates an age situated in the middle part of the middle Cenomanian (Acanthoceras rhotomagense Zone). A. renevieri ranges from early Cenomanian to the middle Cenomanian although doubtfully until the Acanthoceras jukesbrownei Zone, whereas N. fourtaui ranges from the middle Cenomanian (A. rhotomagense Zone) to the base of late Cenomanian.
The presence of N. fourtaui alone above the previous bioevent corresponds to the upper part of the middle Cenomanian (Acanthoceras jukesbrownei Zone)–early late Cenomanian (base of C. (P.) guerangeri Zone). Neolobites vibrayeanus as well as C. (Proeucalycoceras) cf. canitaurinum (subzonal index species) are restricted to the base of late Cenomanian (C. (P) guerangeri Zone). They are associated with Turrilites costatus and Cunningtoniceras sp. Metoicoceras geslinianum is the index species of the eponymous zone (middle part of the late Cenomanian). C. (Gentoniceras) aff. gentoni is also present in this zone.
The presence of Nigericeras gadeni and N. jacqueti indicates a period situated in the upper part of the Metoicoceras geslinianum Zone and the lowermost part of the Neocardioceras juddii Zone. Puzosia sp. is also present. Vascoceras barcoicense exile and V. cauvini are known from Neocardioceras juddii Zone, rather the lower part; but may already appear in the Metoicoceras geslinianum Zone. The Placenticeras aff. kaffrarium correspond to a period in the Neocardioceras juddii Zone (upper part of the late Cenomanian). Rubroceras aff. burroense also characterizes this zone.
The presence of some undeterminate Vascoceras and Pseudaspidoceras does not allow attributing a precise age near the Cenomanian/Turonian boundary (topmost Cenomanian–basal Turonian). In some part of the southern Neo-Tethys margin (Egypt, Jordan) Vascoceras proprium is used to delineate this boundary (see discussion in Meister and Piuz, 2013).
Fagesia (F. catinus, F. tevesthensis) as well as Hoplitoides wohltmanni attest to the presence of the early Turonian. F. tevesthensis could be a little younger (upper part of the early Turonian). Kennedy and Simmons (1991) also cited some early Turonian taxa like Vascoceras durandi, ? Thomasites cf. gongilensis, ? Eotissotia simplex and Wrightoceras sp. which we have not rediscovered and that could represent three other bioevents (Figures 11 and 12). All these bioevents are correlated with the standard zonation. For regional correlations along the southern Neo-Tethys margin we refer to the detailed discussion recently published by Meister and Piuz (2013).
Ammonite distributions along the southern Neo-Tethys margin from Morocco to Oman have recently been presented and discussed by Meister and Piuz (2013). Only worldwide paleogeographical distributions of some characteristic taxa present in Oman are shown from the middle Cenomanian to the early Turonian (Figure 13).
For the middle–early late Cenomanian A. renevieri has a distribution restricted to Europe and western and eastern part of Africa, N. vibrayeanus shows a rather subequatorial/tropical repartition as does C. (P.) canitaurinum. If the latter is not present in Central and North America, it is recorded from South America, Peru and Bolivia, and possibly following Wiese and Schulze (2005) from Venezuela and Columbia. N. fourtaui is endemic to the southern Neo-Tethys margin.
For the late Cenomanian, T. costatus is a cosmopolitan species whereas C. (G.) gentoni is distributed in Europe and eastern and southern part of Africa. P. kaffrarium is only known around Africa. For the early Turonian Fagesia is a cosmopolitan genus. The species F. tevesthensis and F. catinus are also widely distributed, but they are not known in the South Atlantic. H. wohltmanni is present along the southern Neo-Tethys margin, in the Gulf of Guinea and in Central America more or less according to a subequatorial trend.
New discoveries of ammonites in Oman (Adam Foothills) allow further precision of their taxonomy and provide better chronostratigraphical constraints for the Albo-Turonian period. Regionally the sequence of nine bioevents gives greater precision for dating the Nahr Umr and Natih formations, especially for the Natih A and B members. In the Adam Foothills, the ammonite correlations along a West-East transect raises questions regarding the definitions of the lithostratigraphic units of the Natih Formation. Obviously the facies of Natih A and B differs from the western part (Jabals Fitri, Nadah and Salakh NW) to the eastern part (Jabals Salakh, Khaydalah and Madmar) (see Piuz et al., 2014, their figure 2).
A sequence of nine bioevents is correlated with the zonation. Moreover, some ammonite are good temporal markers, among them Neolobites vivrayeanus (Orbigny), Calycoceras (Proeucalycoceras) cf. canitaurinum (Spath), Metoicoceras geslinianum (Orbigny) and Vascoceras cauvini Chudeau. They allow good correlations at a large scale, at least along the southern Neo-Tethys margin. Several taxa including Puzosia, Placenticeras, Cunningtoniceras, P. (Gentoniceras), Nigericeras, Metoicoceras, Rubroceras and Hoplitoides are recorded from Oman for the first time.
From a paleogeographic point of view Oman is a landmark for correlation between western Neo-Tethys (Europe, North Africa, Middle East) and southeast Neo-Tethys (Africa, Madagascar, India. Moreover the presence of Placenticeras in a key period for understanding its evolution (still in discussion) is to be underlined.

Speech by CE at PolyU 80th Anniversary Celebration Dinner (with photos/video)
Following is the speech by the Chief Executive, Mrs Carrie Lam, at the Polytechnic University (PolyU) 80th Anniversary Celebration Dinner today (December 7):
Mr Chan (Chairman of the Hong Kong Polytechnic University Council, Mr Chan Tsz-ching), Timothy (President of the Hong Kong Polytechnic University, Professor Timothy Tong), Carlson (Chairman of the University Grants Committee, Mr Carlson Tong), ladies and gentlemen,
Good evening. It's a great pleasure to be here, to be celebrating the 80th anniversary of the Hong Kong Polytechnic University with you tonight. Without sounding cliché, time really flies. It is more than one year ago that I officiated at the launching ceremony of the University's 80th anniversary celebrations on the university campus in my then capacity as the Chief Secretary for Administration.
PolyU's journey started eighty years ago in a modest, two-storey building on Wood Road in Wan Chai. It was Government Trade School back then, the first publicly funded, post-secondary technical institution in Hong Kong offering courses in mechanical engineering, marine wireless operating and building construction. With the remarkable efforts of its management, staff and students, that trade school has become the PolyU that we all know and admire, an internationally renowned university – innovative, ambitious and endlessly evolving.
PolyU excels in professional education, in applied research and community partnership, all for the benefit and the progress of Hong Kong. Its pursuit of excellence has been applauded internationally. In this year's QS World University Rankings, eight PolyU disciplines were ranked among the world's top 50. The university also climbed to 17th place in Asia this year under the Times Higher Education University Rankings. These cheering results reflect PolyU's longstanding promise: "Opening Minds, Shaping the Future." They also underscore the remarkable development of Hong Kong's higher education sector over the years. Indeed, in this year's QS World University Rankings, five Hong Kong universities placed in the top 100 globally.
In recent years, PolyU and other post-secondary institutions are busily and profitably tapping into the opportunities presented by Mainland China, by Asia in general, and by the world at large. There will be plenty of such opportunities in the future, as the visionary Belt and Road Initiative turns into reality. The Belt and Road Initiative links more than 60 nations on three continents through infrastructure development and in a wealth of other areas, from expanded trade and political ties to culture, education and people-to-people bonds.
Our universities will have a big part to play if we are to take full advantage of the Belt and Road's boundless promise. In this regard, I am very pleased to note that PolyU has very strong regional and global connections, and is committed to weaving an effective global network which further facilitates educational and research development, as well as enhancing academic and cultural exchanges. PolyU was one of the first universities to co-found the University Alliance of the Silk Road in 2015. The Alliance now comprises 124 universities from 32 countries or regions, and has been actively organising a range of activities to broaden students' horizons and enrich their understanding about the Belt and Road regions. More recently, PolyU established the Belt and Road Centre in September 2017. This think tank will pool the interdisciplinary research strengths of the university to work with the public and private sectors, professional bodies and other universities on Belt and Road-related initiatives, as well as integrating them into university curriculum. It is encouraging to see PolyU progressing and contributing so remarkably in these aspects.
But it is nearer home, in the Gaungdong-Hong Kong-Macao Bay Area that Hong Kong universities including PolyU will play a pivotal role in our ambition to develop in the Bay Area an international Innovation & Technology Centre, and in fulfilling my blueprint for I&T development with a view to help diversifying Hong Kong's economy and creating more quality jobs for our next generation. I know such an ambition has to be supported by additional resources in research and development (R&D). Thus, in my maiden Policy Address delivered on October 11, I announced that Government will set aside no less than HK$10 billion as extra funding for university research. I also propose a tax incentive to encourage enterprises to spend more on R&D. Given PolyU's achievements in applied research, I am confident that it will make excellent use of these additional resources.
I take heart as well in PolyU's emphasis on service-learning, knowledge transfer and entrepreneurship. PolyU is the first university in Hong Kong to include service learning as a compulsory component for all students under the four-year curriculum. I am delighted to learn that PolyU students have contributed some 400 000 hours of services to the Hong Kong community through service-learning programmes. PolyU is also among our first higher-education institutions to offer funding and support to promote innovation and entrepreneurship among students, academics and alumni. With the establishment of the PolyU InnoHub earlier this year, I am confident our young innovators and entrepreneurs will expand their cooperation and exchanges with their counterparts in the nearby regions.
Ladies and gentlemen, while we celebrate PolyU's 80th anniversary today, the university is focused firmly on the future. I thank PolyU, particularly President Timothy Tong who has announced his decision to step down in December next year, and everyone involved for what you have done and what you will do for PolyU and Hong Kong. I wish PolyU every success in its future endeavours and wish you all an enjoyable evening.

Brief Fact Summary.
During a divorce the court of appeals instructed the trial court to devise an award of equitable distribution to the wife in compensation for her intangible contributions to the marriage that helped the husband to obtain his medical degree, which he financed without assistance from the wife. The case was appealed.
Synopsis of Rule of Law.
Courts should not apply the doctrine of equitable restitution when dividing property in divorce cases.
Karen (Plaintiff) and Jess (Defendant) Martinez married in 1968. At the time, both had high school educations. The Martinezes had three children between 1970 and 1975. Beginning in 1970, Jess completed the requirements for a bachelor's degree, and then decided to attend medical school. He was in medical school from 1977 until 1981, and financed his education without assistance from his wife. Later, the couple filed for divorce. At issue was how to equitably divide the couple's property. On appeal, the intermediate appellate court instructed the trial court to devise an award of equitable restitution to Karen in compensation for her intangible contributions to the marriage that helped Jess to obtain his medical degree. The case was then appealed to the state supreme court.
Whether courts should apply the doctrine of equitable restitution when dividing property in a divorce cases.
No. The court of appeals' instruction to the trial court is reversed and the case is remanded to the trial court for further proceedings in light of this opinion. Courts should not apply the doctrine of equitable restitution when dividing property in divorce cases.
Dissent.
(Durham, J.): Yes. The majority holds that divorcing spouses have rights only to alimony, child support, and distribution of marital property. These legal rights by themselves are inadequate to ensure fair treatment of divorcing spouses in cases where one spouse obtained a professional degree during the marriage. Because a professional degree is not considered marital property, a spouse who did not obtain the degree is not compensated for the intangible sacrifices he or she made to help the other spouse obtain the degree. For example, a spouse who sacrificed a career to care for children so that the other spouse would be able to obtain a professional degree receives no compensation if the marriage ends in divorce, while the other spouse retains all the benefits of the professional degree. Equity and justice require courts to compensate the spouse's loss of the investment that was made in the marriage. Equitable restitution is but one of many possible doctrines that courts could adopt to accomplish this. Courts might also calculate the financial gains and losses experienced by each spouse as a result of the marriage and financially compensate the spouse with the greater net loss. By rejecting the appellate court's attempt at developing fair divorce procedures, the majority has kept in place a system of laws that treat divorcing spouses unfairly.
Discussion.
The court of appeals' concept of equitable restitution cannot be sustained for three reasons. First, the concept of equitable restitution is based on the proposition that a failed marriage is a venture akin to a commercial partnership in which the spouses invest their time and effort solely for remunerative activities. Second, an award of equitable restitution would be extraordinarily speculative. Although the court of appeals' opinion is somewhat unclear as to what kind of economic interest it intended to create or just how it should be computed, it did state, "An award of equitable restitution will not terminate upon plaintiff's remarriage, and may be payable in lump sum or periodically over time depending on the circumstances of each case." Third, although the court of appeals stated that it rejected the proposition that Dr. Martinez's medical degree should be valued as a property interest and Mrs. Martinez given an interest in it, that court's concept of equitable restitution is essentially indistinguishable. Professional degrees are not marital property. The recipient of an advanced degree obtains that degree on the basis of his or her innate personal talents, capabilities, and acquired skills and knowledge. Such a degree is highly personal to the recipient and has none of the traditional characteristics of property. The Court expresses no opinion on the appropriateness of the other modifications made by the court of appeals in the divorce decree.

CHINESE WOMEN'S STORIES
by Zhang Xinxin and Sang Ye, Chen Yuanbin | Read by Miriam Margolyes
Fiction • 2.5 hrs. • Unabridged • © 1998
What a treasure! Margolyes's reading of these three short essays and one novella offers the listener a rare glimpse into many aspects of everyday life in China. Margolyes's decidedly British accent seems very out of place at first, but her warm, engaging tones and enthusiasm for the prose easily and effortlessly draw the listener into each story. Margolyes shines brightest reading "The Story of Qiuyu," a beautifully written story of a peasant woman seeking justice from the local political machine. The no-frills packaging undersells both this one-of-a-kind collection and the outstanding performance included within. H.L.S. © AudioFile, Portland, Maine [Published: DEC/JAN 00]

Reports of cyber attacks fall, says UK.gov survey: GDPR? Fewer nasties? More targeted attacks? We just don\'t know
Started by chain, July 5

LocationMontreal,Quebec
UK businesses have reported a significant fall in cyber attacks over the last 12 months.
The proportion identifying breaches or attacks in the least year was 32 per cent, compared with 43 per cent in 2018 and 46 per cent in 2017, according to a survey of 1,566 businesses by the Department for Digital, Culture, Media and Sport (DCMS) (PDF).
Those figures echo the Crime Survey for England and Wales, which found that between September 2017 and September 2018, the number of computer misuse incidents among individuals fell from 1.5 million to 1 million.
This was driven, according to Office for National Statistics data, by a significant reduction in computer viruses (down by 45 per cent over the same period).
However, the DCMS report said other factors could be at play such as more investment in cybersecurity, better compliance due to GDPR, or a change in attack behaviour.
For example, those carrying out cyber attacks could be focusing on a narrower (though still numerous) set of businesses.
This fits with another broad trend in the survey showing that, among the 32 per cent of businesses that did identify breaches or attacks, the median number they recall facing has gone up, from two attacks in 2017 to six in 2019.
Of those targeted, phishing attacks were the most common, with 80 per cent having been subject to email scams, while 27 per cent said they had been hit by viruses, spyware or malware.
However, Ken Munro of Pen Test Partners said there are too many variables to make the findings conclusive.
"Are the number of antivirus reports down because organisations (rightly) don't consider them to be attacks/breaches or incidents? Or is it because the antivirus products aren't detecting the types of malware that are being used now?"
He added: "Without analysing the quality of phishing attacks, the data is also meaningless. Are untargeted phishing attempts being filtered out upstream?
"I don't think anything can be concluded from the report other than that 'cyber stuff is still happening and some businesses are taking it more seriously'.
