MORPHOMETRIC VARIATION OF ISLAND POPULATIONS OF Macroglossus spp. (Chiroptera : Pteropodidae)

A total of 395 skulls and skins of Macroglossus were examined, mostly from Indonesia, and some from Philippines, Papua New Guinea and Australia. The use of discriminant [unction analysis recognized six broad grollps of island populations of Macroglossus: The [aura grollp (Nias, Sumaiera, [auia, Bali and NusaPenida ls.), the Nusa Tenggara group (Lombok, Sumbawa, Moyo, Komodo, Rinca, Sumba, Flores, Adonara, Lembatu, Paniar, Alor, Timer, Semau, Roti, Sabu, Kalitnanian, Westem Australia, New Britain, New Ireland and Bum), the Suiatuesi group (Sulauiesi onlv), the Siberui group (Siberut only), the New Guinea group(New Guinea only) and the Philippine group (Philippines only). The [aura group is represented by M. sobrinus Andersen, 1911; the other grollps M. minimus (Geoffroy, 1810). Within M. sobrinus, foursubspecies were recognized. These were M. s. sobrinus (fawa and Sumaiera); M.s. fratemus (Siberut); M. s. subsp. novo A (Bali and Nusa penida); and M. s. sllbsp. novo B (Nias). Within M. minimus, six subspecies were recognized, these were M. m. minim us (Nusa Tenggara and Western Australia); M. m. nanus (New Britain and New Ireland); M. m. lagochilus (Kalimantan, Buru and Madura); M. m. microtus (New Guinea); M. m. fructivorous (Philippines) and M. m. meyeri (Sulouiesi). The taxa can be separated by discriminant function and unioariate analysis of continuously varying characters, in conjunction with the anterooentral ossification projecting forwards from the den tan} symphysis and the fleshy protuberance supportedon tile distal end of the lips by this ossification.Key Words: Fruit-bats, Macroglossus spp..

Mental health first aid training in a workplace setting: A randomized controlled trial [ISRCTN13249129]

BACKGROUND: The Mental Health First Aid training course was favorably evaluated in an uncontrolled trial in 2002 showing improvements in participants' mental health literacy, including knowledge, stigmatizing attitudes, confidence and help provided to others. This article reports the first randomized controlled trial of this course. METHODS: Data are reported on 301 participants randomized to either participate immediately in a course or to be wait-listed for 5 months before undertaking the training. The participants were employees in two large government departments in Canberra, Australia, where the courses were conducted during participants' work time. Data were analyzed according to an intention-to-treat approach. RESULTS: The trial found a number of benefits from this training course, including greater confidence in providing help to others, greater likelihood of advising people to seek professional help, improved concordance with health professionals about treatments, and decreased stigmatizing attitudes. An additional unexpected but exciting finding was an improvement in the mental health of the participants themselves. CONCLUSIONS: The Mental Health First Aid training has shown itself to be not only an effective way to improve participants' mental health literacy but also to improve their own mental health. It is a course that has high applicability across the community

Information needs among women taking part in primary HPV screening in England: a content analysis

Objectives: Introducing primary human papillomavirus (HPV) testing to cervical screening programmes means changes to the results women receive. We explored additional information needs among women undergoing HPV primary screening. / Design: Women were sent a postal questionnaire shortly after receiving their results and 6 and 12 months later. Each questionnaire asked if women had any unanswered questions about cervical screening or HPV testing. Free-text responses constituted the data. Themes were identified using content analysis. / Setting: National Health Service (NHS) Cervical Screening Programme, England. / Participants: 381 women who recorded one or more free-text responses. / Results: The most common theme represented women’s emotional responses and attempts to understand their results. This theme was raised by 45% of women overall, but was as high as 59% in the HPV cleared group. General questions about the cause and epidemiology of HPV were raised by 38% of women and were more common among those testing HPV positive with normal cytology (52%). Questions about the purpose and procedure for HPV testing were most common among HPV-negative women (40%, compared with 16%–24% of the other results groups). Questions about future implications of test results were raised by 19% of women, and this theme was most common among those with persistent HPV. / Conclusions: Despite provision of information alongside screening invitations, women can still have unanswered questions following receipt of their results. Details about the epidemiology of HPV and why cervical screening procedures are changing should be included with screening invitations. Some results groups may benefit from additional tailored information with their results letter

Experiences in applying skills learned in a mental health first aid training course: a qualitative study of participants' stories

BACKGROUND: Given the high prevalence of mental disorders and the comparatively low rate of professional help-seeking, it is useful for members of the public to have some skills in how to assist people developing mental disorders. A Mental Health First Aid course has been developed to provide these skills. Two randomized controlled trials of this course have shown positive effects on participants' knowledge, attitudes and behavior. However, these trials have provided limited data on participants' subsequent experiences in providing first aid. To remedy this, a study was carried out gathering stories from participants in one of the trials, 19–21 months post-training. METHODS: Former course participants were contacted and sent a questionnaire either by post or via the internet. Responses were received from 94 out of the 131 trainees who were contacted. The questionnaire asked about whether the participant had experienced a post-training situation where someone appeared to have a mental health problem and, if so, asked questions about that experience. RESULTS: Post-training experiences were reported by 78% of respondents. Five key points emerged from the qualitative data: (1) the majority of respondents had had some direct experience of a situation where mental health issues were salient and the course enabled them to take steps that led to better effects than otherwise might have been the case; (2) positive effects were experienced in terms of increased empathy and confidence, as well as being better able to handle crises; (3) the positive effects were experienced by a wide range of people with varied expectations and needs; (4) there was no evidence of people over-reaching themselves because of over-confidence and (5) those who attended were able to identify quite specific benefits and many thought the course not only very useful, but were keen to see it repeated and extended. CONCLUSION: The qualitative data confirm that most members of the public who receive Mental Health First Aid training subsequently provide support to people with mental health problems and that this support generally has positive effects

Oldest known pantherine skull and evolution of the tiger

The tiger is one of the most iconic extant animals, and its origin and evolution have been intensely debated. Fossils attributable to extant pantherine species-lineages are less than 2 MYA and the earliest tiger fossils are from the Calabrian, Lower Pleistocene. Molecular studies predict a much younger age for the divergence of modern tiger subspecies at <100 KYA, although their cranial morphology is readily distinguishable, indicating that early Pleistocene tigers would likely have differed markedly anatomically from extant tigers. Such inferences are hampered by the fact that well-known fossil tiger material is middle to late Pleistocene in age. Here we describe a new species of pantherine cat from Longdan, Gansu Province, China, Panthera zdanskyi sp. nov. With an estimated age of 2.55–2.16 MYA it represents the oldest complete skull of a pantherine cat hitherto found. Although smaller, it appears morphologically to be surprisingly similar to modern tigers considering its age. Morphological, morphometric, and cladistic analyses are congruent in confirming its very close affinity to the tiger, and it may be regarded as the most primitive species of the tiger lineage, demonstrating the first unequivocal presence of a modern pantherine species-lineage in the basal stage of the Pleistocene (Gelasian; traditionally considered to be Late Pliocene). This find supports a north-central Chinese origin of the tiger lineage, and demonstrates that various parts of the cranium, mandible, and dentition evolved at different rates. An increase in size and a reduction in the relative size of parts of the dentition appear to have been prominent features of tiger evolution, whereas the distinctive cranial morphology of modern tigers was established very early in their evolutionary history. The evolutionary trend of increasing size in the tiger lineage is likely coupled to the evolution of its primary prey species

Parental attitudes and information needs in an adolescent HPV vaccination programme

We sent a questionnaire to 38% (1084) of 2817 parents whose daughters had been offered human papillomavirus vaccination and who had agreed to participate. Of these, 60% (651) returned a questionnaire. Responses suggested that fact sheets and parent information evenings confirmed, rather than changed, consent decisions. The views of active refusers on safety and efficacy may be difficult to change, lowering vaccine coverage

Describing whisker morphology of the Carnivora

One of the largest ecological transitions in carnivoran evolution was the shift from terrestrial to aquatic lifestyles, which has driven morphological diversity in skulls and other skeletal structures. In this paper we investigate the association between those lifestyles and whisker morphology. However, comparing whisker morphology over a range of species is challenging since the number of whiskers and their positions on the mystacial pads vary between species. Also, each whisker will be at a different stage of growth and may have incurred damage due to wear and tear. Identifying a way to easily capture whisker morphology in a small number of whisker samples would be beneficial. Here, we describe individual and species variation in whisker morphology from two-dimensional scans in red fox, European otter and grey seal. A comparison of long, caudal whiskers shows interspecies differences most clearly. We go on to describe global whisker shape in 24 species of carnivorans, using linear approximations of curvature and taper, as well as traditional morphometric methods. We also qualitatively examine surface texture, or the presence of scales, using Scanning Electron Microscope images. We show that gross highly conserved, with whisker curvature and taper obeying simple linear relationships with length. However, measures of whisker base radius, length, and maybe even curvature, can vary between species and substrate preferences. Specifically, the aquatic species in our sample have thicker, shorter whiskers that are smoother, with less scales present than those of terrestrial species. We suggest that these thicker whiskers may be stiffer and able to maintain their shape and position during underwater sensing, but being stiffer may also increase wear
