Abstract

Despite substantial progress for women in science, women remain underrepresented in many aspects of the scholarly publication process. We examined how the gender diversity of editors and reviewers changed over time for six journals in ecology and evolution (2003–2015 for four journals, 2007–2015 or 2009–2015 for the other two), and how several aspects of the peer review process differed between female and male editors and reviewers. We found that for five of the six journals, women were either absent or very poorly represented as handling editors at the beginning of our dataset. The representation of women increased gradually and consistently, with women making up 29% of the handling editors (averaged across journals) in 2015, similar to the representation of women as last authors on ecology papers (23% in 2015) but lower than the proportion of women among all authors (31%) and among members of the societies that own the journals (37%–40%). The proportion of women among reviewers has also gradually but consistently increased over time, reaching 27% by 2015. Female editors invited more female reviewers than did male editors, and this difference increased with age of the editor. Men and women who were invited to review did not differ in whether they responded to the review invitation, but, of those that responded, women were slightly more likely to agree to review. In contrast, women were less likely than men to accept invitations to serve on journal editorial boards. Our analyses indicate that there has been progress in the representation of women as reviewers and editors in ecology and evolutionary biology, but women are still underrepresented among the gatekeepers of scholarly publishing relative to their representation among researchers.

Abstract

Neuro-ophthalmic evaluation is a crucial component of the diagnostic and prognostic assessment of pituitary disease and compressive chiasmopathy, and can inform the timing of vision-restoring tumour resection surgery. The most common disease affecting the pituitary with neuro-ophthalmic implications are pituitary adenomas. Neuro-ophthalmic manifestations include decreased vision, abnormal colour vision and impaired visual field or diplopia. The recognition of these syndromes is critical to achieve early diagnosis and treatment and to improve prognosis. The pattern of vision loss in chiasmal compression is determined by the anatomical relationship between the pituitary lesion and optic chiasm, and potential visual field defects include bitemporal deficits, junctional scotomas, monocular cecocentral defects, and incongruous homonymous hemianopias. Rarer neuro-ophthalmic manifestations of pituitary disease include ophthalmoplegia, nystagmus, and obstructive hydrocephalus. There is growing evidence that demonstrates the strong diagnostic utility of optical coherence tomography (OCT) parameters in detecting the presence of compressive chiasmopathy, as well as the prognostic ability to predict the rate and degree of visual recovery following decompression surgery. Long-term neuro-ophthalmic monitoring is critical for detecting delayed vision loss following resection surgery, which may represent tumour recurrence or secondary complications.

Abstract

BACKGROUND: Discrimination, bullying and sexual harassment (DBSH) impact the psychological well-being of doctors and contribute to poor health outcomes. The Royal Australian and New Zealand College of Ophthalmologists (RANZCO) commissioned independent surveys to evaluate DBSH among members/trainees. METHODS: Anonymous online surveys by Best Practice Australia were undertaken in 2015 and 2018. Cross-sectional analysis was prevalence of perceived DBSH, rates of reporting, intervention and resolution undertaken. Response rate was 50% (658/1319) in 2015 and 40% (557/1401) in 2018. In both surveys, 29% were female. This is representative of the distribution of the RANZCO members. RESULTS: In a 2015 survey, 37.6% of respondents experienced DBSH, with prevalence being the highest for females (62.3%; N = 104 cf males 27.7%; N = 167) and trainees (49.2%; N = 61). In 2018, 49.2% of respondents reported DBSH with rates low for all forms of DBSH (22%-29%). Sexual harassment was reported by 12% and the least discussed or reported. Respondents strategy for taking action included draw on personal support network (25-43%), official complaints to supervisors (16-22%), human resources (2%-10%) and RANZCO (0%-6%). Reasons for not taking action included fear of impact of future career options (54.1%-60.7%), fear of victimization (35.7%-50.4%) and afraid of not being believed (31.9%-52.4%). Satisfactory resolution rates were 6% to 25%. A majority of respondents (77%) were positive about RANZCO initiatives. CONCLUSIONS: DBSH is commonly reported by RANZCO members with female ophthalmologists more than two times more likely to experience any one of the four behaviours, three times more likely to experience discrimination and six times for sexual harassment. Fear of compromising personal and career progression contribute to low levels of reporting.

Abstract

The question "What drove foragers to farm?" has drawn answers from many different disciplines, often in the form of verbal models. Here, we take one such model, that of the ideal free distribution, and implement it as an agent-based computer simulation. Populations distribute themselves according to the marginal quality of different habitats, predicting settlement patterns and subsistence methods over both time and space. Our experiments and our analyses thereof show that central conclusions of the ideal free distribution model are reproduced by our agent-based simulation, while at the same time offering new insights into the theory's underlying assumptions. Generally, we demonstrate how agent-based models can make use of empirical data to reconstruct realistic environmental and cultural contexts, enabling concrete tests of the explanatory power of anthropological models put forward to explain historical developments, such as agricultural transitions, in specific times and places.

17. The role of change management in improving policy effectiveness in the SANDF

Abstract

Armed forces the world over have three primary functions – force development, force deployment and force employment. Defence policy plays a guiding role in all of these, but it is especially important in establishing the rationale for the creation of credible military deterrence. Usually, a defence policy presupposes the development of armed forces that are effective at executing their mandate, a condition that is measurablein terms of the discipline, skill and quality of the organisation. The study on which this article reports, used this concept to describe how change management – especially by focusing on incorporating effective prioritisation – could enhance the current defence policy. A general analysis of South African defence policy publications indicates that, indeed, the policymakers had thoroughly considered the effectiveness of the armed forces when they wrote the White Paper on Defence of 1996 and the Defence Review of 1998. By 2006, the South African Army had interpreted national defence policy and formulated a future strategy of its own very much in alignment with the ‘modern system’ approach of the original policy publications. The present study suggests that the principal reason for the large variance between defence policy, military capabilities, and real operational demands stems from the lack of effective prioritisation of defence. This article, therefore, concludes that the South African National Defence Force (SANDF) has been largely unsuccessful in complying with the demands of defence policy, irrespective of the fact that the policy by itselfmay be obsolete and/or inappropriate for the South African context. Furthermore, it is concluded that military effectiveness in meeting current operational demands is also doubtful. Finally, the schizophrenic organisational culture of the defence force may be the primary cause of its moving ever closer to reneging on its constitutional mandate.

19. Integrating epistemic action (active vision) and pragmatic action (reaching): A neural architecture for camera-arm robots

Abstract

The active vision and attention-for-action frameworks propose that in organisms attention and perception are closely integrated with action and learning. This work proposes a novel bio-inspired integrated neural-network architecture that on one side uses attention to guide and furnish the parameters to action, and on the other side uses the effects of action to train the task-oriented top-down attention components of the system. The architecture is tested both with a simulated and a real camera-arm robot engaged in a reaching task. The results highlight the computational opportunities and difficulties deriving from a close integration of attention, action and learning.

26. Students' perceptions of the value of a self-study writing assignment.

Author

Meyer JA, Fisher BJ, and Pearl PS

Abstract

The purpose of this study was to examine students' perceptions of a self-study assignment, a requirement for a life-span human development course. A survey assessing attitudes regarding the value of the writing assignment was completed by 278 students. Results suggested that students had an overall positive evaluation of the assignment. The majority of students indicated that the assignment increased their self understanding, understanding of course concepts, and their ability to apply those concepts. Students believed the assignment made the course more meaningful. [ABSTRACT FROM AUTHOR]

Abstract

This book explores the ways in which four visual artists make sense of referentialism and emotion in music. By listening to five art songs by Schubert, Strauss, Fauré and Berlioz they were inspired to create new artworks as a result of their understanding of the meaning of the art songs. This was done without an understanding of the text, and the artists had to rely on referential meaning in music as well as the perceived or evoked emotions elicited by listening to the art songs. The artworks created as a result of this project were exhibited at the Aardklop National Arts Festival, entitled Nagmusiek. This was a multi-modal exhibition featuring music, art and text. This book employs Artistic Research and Phenomenology in order to understand this phenomenon, as I explored the artists’ creative processes, experiences and the tacit knowledge embedded in their artefacts. This book would provide readers access to 20 new artworks, each created as a result of the artists’ interpretation of the meaning they ascribed to art song. Their creative process is also examined and synthesised with existing literature on emotion and referentialism in music.
