Opis:
Nursing aides are particularly susceptible to manual handling injuries because they have the primary responsibility for heavy lifting. The aim of this study was to determine why a specific group of nursing aides have the highest manual handling injury rate in their hospital. The study investigated the adequacy of the manual handling training program, knowledge of manual handling, mechanical aid availability, and use of mechanical aids. Results indicated that the nursing aides’ manual handling knowledge was adequate but that they rarely used mechanical aids. This lack of use of aids was in part due to an over-reliance on their own strength and abilities. This may have been due to a lack of suitable mechanical aids on the wards or a lack of familiarity with the available aids. This study suggests that neither training alone nor the purchase of equipment alone is likely to resolve manual handling problems.

Opis:
An incomplete salamander dentary (AMNH FARB 22965) described herein from the upper Maastrichtian Lance Formation, Wyoming, USA, exhibits a puzzling suite of features. Four features—a prominent bony trough extending anteriorly and curving upwards along the lingual surface of the ramus, lack of an obvious Meckelian fossa or groove, an apparent gap in the tooth row, and a symphysial-like first tooth—are likely anomalies. However, the remaining features are interpreted as normal structures and suggest that AMNH FARB 22965 represents a new genus and species of batrachosauroidid, an extinct family of neotenic salamanders that were prominent components of Cretaceous to Neogene freshwater and floodplain paleocommunities in North America and Europe. The new taxon differs from other batrachosauroidids in a unique suite of dentary and dental features, most notably in having a lingual bony flange paralleling the posterior two-thirds of the dentary tooth row, a prominent and robust coronoid process bearing a grooved anterior face, and the anterior portion of the corpus dentalis behind the symphysis is broadly expanded ventrolingually. The presence of a third batrachosauroidid taxon in the Lance Formation was unexpected, considering that the formation has been well sampled and that its two previously recognized batrachosauroidids, namely Opisthotriton kayi and Prodesmodon copei, are known by abundant isolated bones, including dozens of dentaries, from numerous localities in the unit and elsewhere in the North American Western Interior. Known by a unique dentary from the Bushy Tailed Blowout locality, the taxon represented by AMNH FARB 22965 evidently was uncommon within the Lance Formation paleoenvironment.

Opis:
Characters of the jaws and frontals are often used to differentiate albanerpetontid genera and species, yet the reliability of these characters has rarely been examined. Frontals are diagnostic for the genera Albanerpeton and Celtedens and for species in the latter genus. The value of frontals at the specific level in Celtedens may be inflated by lack of information about variation in jaw structure. Characters of the frontals, jaws, and body size differentiate species of Albanerpeton. Differential diagnoses are presented for the Albanerpetontidae based on cranial and vertebral characters and for the two named genera based on frontal characters. Each genus is characterized by one autapomorphy: fused frontals triangular in Albanerpeton and internasal process bulbous in Celtedens. An enigmatic albanerpetontid from the Middle Jurassic (upper Bathonian) of England has a unique mixture of frontal and premaxillary character states that precludes it from being included in either Celtedens or Albanerpeton.This leaves the oldest occurrences of the two genera in, respectively, the Late Jurassic (Kimmeridgian) and Early Cretaceous (latest Aptian/earliest Albian).
Rodzaje albanerpetodontów klasyfikowano na podstawie cech morfologicznych szczęk i kości czołowych, ale rzadko zastanawiano się nad przydatnością taksonomiczną tych cech. Budowa kości czołowych jest diagnostyczna dla rodzajów Albanerpeton i Celtedens oraz gatunków w obrębie tego ostatniego (zwłaszcza, że brak jest danych na temat zróżnicowania morfologii szczęk w obrębie tego rodzaju). W obrębie rodzaju Albanerpeton gatunki wyróżniają się cechami kości czołowych i szczęk oraz rozmiarami ciała. Podano diagnozy różnicujące dla obu rodzajów opisanych na podstawie powyższych cech, obejmujące także morfologię kręgów. Każdy z rodzajów odznacza się jedną autapomorfią: Albanerpeton - trójkątnymi zrośniętymi kośćmi czołowymi, a Celtedens - pękatym wyrostkiem międzynosowym tych kości. Zagadkowy albanerpetodont ze środkowej jury (baton) Anglii ma mieszane cechy, nie pozwalające zaliczyć go do wyżej wymienionych. Oznacza to, że Celtedens znany jest od późnej jury (kimeryd) a Albanerpeton - od wczesnej kredy (apt/alb).

Opis:
This paper presents findings from an extensive study into factors that impact upon the high rate of injuries due to mechanical equipment, especially in small manufacturing firms. Issues relating to knowledge of health and safety issues and to management practices have been shown to be extremely important with regards to safety in smaii businesses. Knowledge and awareness of hazards were found to be relatively low and few respondents, especially managers, had received adequate safety training. Managers did not regard the identification and control of risks as a priority. Workplaces generally lacked effective safety management procedures such as safety rules and regulations, procedures for recording and learning from accidents, and clearly defined responsibilities for safety. Some issues requiring further investigation, and some recommendations for improving safety in small businesses, are presented.

Opis:
We review the fossil record of Asian albanerpetontids. The three dentaries previously attributed to the two species of Nukusurus Nessov, 1981 (lower Cenomanian and Coniacian, Uzbekistan) are from albanerpetontids, but none are distinctive below the familial level. We thus designate the names Nukusurus, N. insuetus Nessov, 1981, and N. sodalis Nessov, 1997 as nomina dubia within the Albanerpetontidae. Two dentaries (lower Cenomanian, Uzbekistan) described herein for the first time supplement the known record of Asian albanerpetontids. The holotype atlas and only specimen of the supposed albanerpetontid Bishara backa Nessov, 1997 (upper Santonian-?Campanian, Kazakhstan) is shown to be from a salamander, not an albanerpetontid. Our study recognizes Albanerpeton (Cretaceous-Miocene, North America and Europe) and Celtedens (Middle Jurassic-Lower Cretaceous, Europe) as the only valid albanerpetontid genera. Limited evidence favors one or more dispersals from Europe or Norttr America to Asia in the medial Cretaceous as the major biogeographic event in the history of Asian albanerpetontids.
Rewizja azjatyckiego zapisu kopalnego albanerpetontydów pozwoliła potwierdzić obecność tej grupy na podstawie dwóch żuchw z dolnego cenomanu Uzbekistanu, opisanych tu po raz pierwszy, oraz trzech okazów opisanych wcześniej przez Nesowa z dolnego cenomanu i koniaku Uzbekistanu. Materiał nie wykazuje jednak cech diagnostycznych pozwalających go określić poniżej szczebla rodzajowego. Dlatego nazwy Nukusurus, N. insuetus Nessov, 1981 i N. sodalis Nessov, 1997 wypada uznać za nomina dubia. Holotyp domniemanego albanerpetontyda Bishara backa Nessov, 1997 (górny santon-?kampan Kazachstanu) - pojedynczy dźwigacz - należy natomiast do salamandry, a nie albanerpetontyda. Tak więc jedynymi ważnymi rodzajami albanerpetontydów pozostają Albanerpeton (kreda-miocen, Ameryka Północna i Europa) oraz Celtedens (środkowa jura-dolna kreda, Europa). Na podstawie ograniczonego materiału kopalnego można przypuszczać, że w połowie kredy doszło do jednorazowego lub kilkakrotnego zasiedlenia Azji przez albanerpetontydy z Europy lub Ameryki Północnej.

Opis:
A new albanerpetontid, Wesserpeton evansae gen. et sp. nov., from the Early Cretaceous (Barremian) Wessex Formation of the Isle of Wight, southern England, is described. Wesserpeton is established on the basis of a unique combination of primitive and derived characters relating to the frontals and jaws which render it distinct from currently recognized albanerpetontid genera: Albanerpeton (Late Cretaceous to Pliocene of Europe, Early Cretaceous to Paleocene of North America and Late Cretaceous of Asia); Celtedens (Late Jurassic to Early Cretaceous of Europe); and Anoualerpeton (Middle Jurassic of Europe and Early Cretaceous of North Africa). Although Wesserpeton exhibits considerable intraspecific variation in characters pertaining to the jaws and, to a lesser extent, frontals, the new taxon differs from Celtedens in the shape of the internasal process and gross morphology of the frontals in dorsal or ventral view. It differs from Anoualerpeton in the lack of pronounced heterodonty of dentary and maxillary teeth; and in the more medial loca− tion and direction of opening of the suprapalatal pit. The new taxon cannot be referred to Albanerpeton on the basis of the morphology of the frontals. Wesserpeton currently represents the youngest record of Albanerpetontidae in Britain.

Opis:
A third albanerpetontid genus, Anoualerpeton gen. nov., is erected for two new species: An. unicussp. nov. (type species) from the Early Cretaceous (Berriasian) of Morocco and An. priscus sp. nov. from the Middle Jurassic (late Bathonian) of England. Anoualerpeton differs from the exclusively Laurasian albanerpetontid genera Albanerpeton (Early Cretaceous– Paleocene, North America; Miocene, Europe) and Celtedens (?Late Jurassic and Early Cretaceous, Europe) in a unique combination of primitive and derived character states of the jaws and azygous frontals. Monophyly of Anoualerpeton is supported by two synapomorphies of the maxilla and dentary (occlusal margin convex in labial outline and teeth strongly heterodont in size anteriorly) that are convergent with an unrelated, relatively derived Late Cretaceous species of Albanerpeton from North America. The two species of Anoualerpeton differ in character states of the premaxilla and azygous frontals. Cladistic analysis of 20 characters scored for ten albanerpetontid taxa postulates Anoualerpeton as the sister−taxon of Albanerpeton + Celtedens. The sister−pair of Albanerpeton + Celtedensis founded on one or, perhaps, two premaxillary synapomorphies. Anoualerpeton unicus documents the only known Gondwanan occurrence for the Albanerpetontidae and provides a minimum age of basal Cretaceous for the establishment of the clade in Africa. Characters of the mandible, vertebrae, and limbs support the interpretation that Ramonellus (Aptian; Israel) is a caudate, not an albanerpetontid.
