Geology of the Shepton Mallet area (Somerset)
Apart from the urban sprawl of Shepton Mallet, the area is dominantly rural with only a
scatter of small hamlets. The area is mostly underlain by Jurassic sediments, with the Blue
Lias occupying over 50 per cent of the ground. Carboniferous rocks occur in some of the
deeper valleys in the northern part of the area, with the Mercia Mudstone and Penarth
groups cropping out mainly in the south-west. Higher parts of the Lias Group, together
with the Inferior Oolite and Fuller’s Earth crop out in the east of the area.
The highest ground is about 246 m O.D. in the north-east; the lowest ground is about
70 m O.D. in the south-west. The principal drainage is westwards via the River Sheppey in
the north, and unnamed streams in the south-west.
Outside Shepton Mallet, agriculture is the main industry of the region with a
predominance of dairy farming on the heavier soils, and arable farming on the lighter soils
developed on the Inferior Oolite. There is very little woodland in the area. In the past,
quarrying of limestone (Carboniferous, Blue Lias and Inferior Oolite) was an important
industry, but extraction is now limited to the Inferior Oolite in the Doulting area.
The Shepton Mallet area of this report comprises 1: 10 000 Sheet ST64SW. Figures in
square brackets are National Grid references and fall within 100-km square ST. The grid

Tmetoceratidae (Ammonitina) fauna from the Gerecse Mts (Hungary)
Abstract
Taxonomic and stratigraphic problems of the family Tmetoceratidae and the genera Dumortieria, Catulloceras, Cotteswoldia, Pleydellia and Tmetoceras included in it are briefly discussed. Fifteen species of Tmetoceratidae are described and illustrated from the Upper Toarcian-Aalenian ammonite assemblages of the Gerecse Mts (NE Transdanubian Range, Hungary). The fauna described here is closely allied to the Mediterranean Province of the Mediterranean-Caucasian Realm
Customer emotions in service failure and recovery encounters
Emotions play a significant role in the workplace, and considerable attention has been given to the study of employee emotions. Customers also play a central function in organizations, but much less is known about customer emotions. This chapter reviews the growing literature on customer emotions in employee–customer interfaces with a focus on service failure and recovery encounters, where emotions are heightened. It highlights emerging themes and key findings, addresses the measurement, modeling, and management of customer emotions, and identifies future research streams. Attention is given to emotional contagion, relationships between affective and cognitive processes, customer anger, customer rage, and individual differences
Observational and genetic associations between cardiorespiratory fitness and cancer: a UK Biobank and international consortia study
Background
The association of fitness with cancer risk is not clear.
Methods
We used Cox proportional hazards models to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for risk of lung, colorectal, endometrial, breast, and prostate cancer in a subset of UK Biobank participants who completed a submaximal fitness test in 2009-12 (N = 72,572). We also investigated relationships using two-sample Mendelian randomisation (MR), odds ratios (ORs) were estimated using the inverse-variance weighted method.
Results
After a median of 11 years of follow-up, 4290 cancers of interest were diagnosed. A 3.5 ml O2⋅min−1⋅kg−1 total-body mass increase in fitness (equivalent to 1 metabolic equivalent of task (MET), approximately 0.5 standard deviation (SD)) was associated with lower risks of endometrial (HR = 0.81, 95% CI: 0.73–0.89), colorectal (0.94, 0.90–0.99), and breast cancer (0.96, 0.92–0.99). In MR analyses, a 0.5 SD increase in genetically predicted O2⋅min−1⋅kg−1 fat-free mass was associated with a lower risk of breast cancer (OR = 0.92, 95% CI: 0.86–0.98). After adjusting for adiposity, both the observational and genetic associations were attenuated.
Discussion
Higher fitness levels may reduce risks of endometrial, colorectal, and breast cancer, though relationships with adiposity are complex and may mediate these relationships. Increasing fitness, including via changes in body composition, may be an effective strategy for cancer prevention
A redescription of the fossil coleoid cephalopod genus Palaeololigo Naef, 1921 (Decapodiformes: Palaeololiginidae) and its relationship to Recent squids
Neocoleoid cephalopods are poorly represented in the fossil record and fossils which can be confidently aligned with extant species are very scarce. The rare Solnhofen genus Palaeololigo is an exception to this, showing marked resemblance to Recent squids. Naef misinterpreted the structure of the fossilized gladius of Palaeololigo and the present study redescribes the genus. The gladius and fossilized fin impressions of Palaeololigo closely resemble that of the extant decapodiform squid genera Bathyteuthis and Chtenopteryx (Superfamily Bathyteuthoidea). The possible relationship between Palaeololigo and the bathyteuthoids and their position in decapodiform phylogenetics is discussed

Lower Jurassic (Pliensbachian) ammonites from Bornholm, Baltic Sea, Denmark
The Jurassic succession of the island of Bornholm in the Baltic Sea includes the Hettangian – lowermost Pliensbachian Rønne Formation, the Lower Pliensbachian Hasle Formation, the Upper Pliensbachian – (?)Lower Aalenian Sorthat Formation and the (?)Upper Aalenian – Bathonian Bagå Formation. Ammonites are only known from the Hasle Formation, and all available ammonite specimens from this formation are described and figured. Material reported by previous authors has been re-examined, together with previously undescribed specimens. Nine genera and eleven species are recognised. The ammonites show that the rocks from which they were collected fall into the Lower Pliensbachian (Carixian) Substage. The lowermost subzone proved in the Hasle Formation is the basal Taylori Subzone of the Jamesoni Zone of the Northwest European Subboreal standard zonation, which marks a marine transgression over underlying marginal marine beds without ammonites belonging to the Rønne Formation. All subzones of the Jamesoni Zone are proved together with the Valdani Subzone of the Ibex Zone. The Upper Pliensbachian (Domerian) Substage, previously reported, is now thought to be unproved by ammonite evidence. The underlying and overlying Rønne and Sorthat Formations are dated by dinoflagellate cysts and terrestrial palynomorphs, and the ammonite occurrences provide important control points for palynostratigraphic dating of the succession
