The control of rank-abundance distributions by a competitive despotic species.

Accounting for differences in abundances among species remains a high priority for community ecology. While there has been more than 80 years of work on trying to explain the characteristic S shape of rank-abundance distributions (RADs), there has been recent conjecture that the form may not depend on ecological processes per se but may be a general phenomenon arising in many unrelated disciplines. We show that the RAD shape can be influenced by an ecological process, namely, interference competition.

The effects of climate change and land-use change on demographic rates and population viability.

Understanding the processes that lead to species extinctions is vital for lessening pressures on biodiversity. While species diversity, presence and abundance are most commonly used to measure the effects of human pressures, demographic responses give a more proximal indication of how pressures affect population viability and contribute to extinction risk. We reviewed how demographic rates are affected by the major anthropogenic pressures, changed landscape condition caused by human land use, and climate change.

Nutrition therapy in the optimisation of health outcomes in adult patients with moderate to severe traumatic brain injury: findings from a scoping review.

Introduction: Patients who have sustained traumatic brain injury (TBI) have increased nutritional requirements yet are often unable to eat normally, and adequate nutritional therapy is needed to optimise recovery. The aim of the current scoping review was to describe the existing evidence for improved outcomes with optimal nutrition therapy in adult patients with moderate to severe TBI, and to identify gaps in the literature to inform future research.

Methods: Using an exploratory scoping study approach, Medline, Cinahl, Embase, CENTRAL, the Neurotrauma reviews in the Global Evidence Mapping (GEM) Initiative, and Evidence Reviews in Acquired Brain Injury (ERABI) were searched from 2003 to 14 November 2013 using variations of the search terms 'traumatic brain injury' and 'nutrition'.

Variation in abundance of nectarivorous birds: does a competitive despot interfere with flower tracking?

Adaptive resource tracking in space and time may be disrupted by the modification of resources and competitors. Major global change drivers (e.g.

"Continuity of care" experiences in midwifery education: perspectives from diverse stakeholders.

At least 20 continuity-of-care experiences are compulsory for student midwives in Australia, but little is known about this learning component. This paper presents an analysis of continuity experiences in one Region, incorporating diverse stakeholder perspectives from student midwives, maternity managers and registered midwives, with the aim of better understanding and optimizing experiences. Qualitative methods were utilized, employing mainly focus groups.

Chromatinized Protein Kinase C-θ: Can It Escape the Clutches of NF-κB?

We recently provided the first description of a nuclear mechanism used by Protein Kinase C-theta (PKC-θ) to mediate T cell gene expression. In this mode, PKC-θ tethers to chromatin to form an active nuclear complex by interacting with proteins including RNA polymerase II, the histone kinase MSK-1, the demethylase LSD1, and the adaptor molecule 14-3-3ζ at regulatory regions of inducible immune response genes. Moreover, our genome-wide analysis identified many novel PKC-θ target genes and microRNAs implicated in T cell development, differentiation, apoptosis, and proliferation.

Farmer health and adaptive capacity in the face of climate change and variability. Part 1: Health as a contributor to adaptive capacity and as an outcome from pressures coping with climate related adversities.

This paper examines the role farmers' health plays as an element of adaptive capacity. The study examines which of twenty aspects of adaptation may be related to overall health outcomes, controlling for demographic and on-farm-factors in health problems. The analysis is based on 3,993 farmers' responses to a national survey of climate risk and adaptation.

Climate change and farmers' mental health: risks and responses.

Climate change is exacerbating climate variability, evident in more frequent and severe weather-related disasters, such as droughts, fires, and floods. Most of what is known about the possible effects of climate change on rural mental health relates to prolonged drought. But though drought is known to be a disproportionate and general stressor, evidence is mixed and inconclusive.

The effect of Personal Digital Assistants in supporting the development of clinical reasoning in undergraduate nursing students: a systematic review.

Background: The objective of this review was to determine whether the use of Personal Digital Assistants (PDAs) would provide greater support in developing undergraduate nursing students' clinical reasoning, in comparison to more traditional resources such as textbooks.

Search Strategy: The search strategy sought to identify published data from five electronic databases: CINAHL, Medline, Cochrane Library, Meditext and Scopus. Unpublished literature was also sought in digital dissertations, conference proceedings, relevant scholarly websites and reference lists.

The work plan for the newly created IUHPE Vice President for Strategy and Governance.

The position of Vice President for Strategy and Governance was created at the first full meeting of the International Union for Health Promotion and Education Board of Trustees in June 2007 in Vancouver, Canada. Specific duties were developed for the position and the newly elected Vice President developed a work plan for the period of 2007-10. This paper describes the responsibilities of the newly created Vice Presidency and the work plan developed to meet those responsibilities.

Enhancing case managers' skills in the assessment and management of antipsychotic medication side-effects.

Objective: Our goal was to reduce the prevalence of antipsychotic medication side-effects by providing a short-term training program on the assessment and management of side-effects to case managers.

Method: Forty-four patients in receipt of community-based mental health services were allocated to comparison (n = 20) and intervention (n = 24) groups based on the health service district in which they resided. While case managers working with the intervention group attended a short-term training program to improve their assessment and management of neuroleptic side-effects, case managers providing services to the comparison group received no additional training.

Reasons why women who have mastectomy decide to have or not to have breast reconstruction.

Breast reconstruction after mastectomy is chosen by approximately 10 percent of Australian women. Younger women are more likely to have this surgical procedure. This suggests that there may be many factors determining this choice.
