Individual perceptions of physical activity in a community-level initiative in North Queensland, Australia
Introduction: Community-level health initiatives advertise the benefits of physical activity, however, it is unknown how personally relevant these promoted benefits are to those who take part. The purpose of this study was to describe the personal experience of participation in the health programs, and to identify how appropriate the participants felt the programs were. Methods: Participants were rural North Queensland residents participating in Australian federal government funded health initiative programs offered by their local council. There were 25 participants (10 males, 15 females) whose ages ranged from 47 to 79. Twenty-one were in the 12-week Diabetes Australia Beat It program, and four participants were in a 10-week water aerobics program. Qualitative data was provided by participants during semi-structured interviews which asked about current exercise habits, reason for taking part in the program and opinions about the program and facilitators.
Results: Thematic Analysis was used to analyze the data. It was an inductive analysis that assessed semantic themes from a realist perspective. The themes fond detail the personal definition of exercise (Exercise to me), the physical benefits of exercise (Keep yourself, Future fitness, Observed changes), and the psychological benefits of exercise (socializing, challenging oneself, sense of achievement).
Conclusions: The benefits that participants felt they gained from the physical fitness program, and their reasons for attending were different to the programs' expected outcomes. Programs should aim to appeal and cater to the needs of a wide group of people who have limited access to exercise facilities and health behaviour programs
Integrated reporting vs. sustainability reporting for corporate responsibility in South Africa
Large corporates have come under increasing pressure to conduct their business in a more transparent and responsible manner. In order for business to fulfil its obligations under the ethic of accountability stakeholders must be given relevant, timely, and understandable information about their activities through corporate reports. The conventional company reports on annual financial performance, sustainability and governance disclosures often fail to make the connection between the organisation's strategy, its financial results and performance on environmental, social and governance issues. Recognising the inherent shortcomings of existing reporting models, there is a growing trend to move towards integrated reporting. South Africa has been one of the most innovative countries in terms of integrated corporate reporting. Since 2010 companies primarily listed on the country's major stock exchange have been required to produce an integrated report as opposed to the former sustainability report. The aim in this study is to review the development of integrated reporting by large corporates in South Africa and assess the impact of the required transition from sustainability reporting to integrated reporting on non-financial disclosure of eight South African corporates using content analysis of annual reports.

Enzymatic enhancement of the free monoterpenol content of a Portuguese wine from a single, native grape variety; “Trajadura”
Three important monoterpene aroma releasing activities contained in an Aspergillus niger preparation were investigated for effects of pH, alcohol, SO2, temperature and concentration of glucose. Application of the enzyme preparation during microvinification or wine maturation of a Portuguese white wine from Trajadura grapes, increased monoterpene content roughly 2-fold and 3-fold respectively
Opening dialogue and fostering collaboration: different ways of knowing in fisheries research
We set out to explore some of the impediments which hinder effective communication among fishers, fisheries researchers and managers using detailed ethnographic research amongst commercial handline fishers from two sites- one on the southern Cape coast and the other on the west coast of South Africa. Rather than assuming that the knowledge of fishers and scientists is inherently divergent and incompatible, we discuss an emerging relational approach to working with multiple ways of knowing and suggest that this approach might benefit future collaborative endeavours. Three major themes arising from the ethnographic fieldwork findings are explored: different classifications of species and things; bringing enumerative approaches into dialogue with relational approaches; and the challenge of articulating embodied ways of relating to fish and the sea. Although disconcertments arise when apparently incommensurable approaches are brought into dialogue, we suggest that working with multiple ways of knowing is both productive and indeed necessary in the current South African fisheries research and management contexts. The research findings and discussion on opening dialogue offered in this work suggest a need to rethink contemporary approaches to fisheries research in order to mobilise otherwise stagnant conversations, bringing different ways of knowing into productive conversation

A dynamic explanation for the origin of the western Mediterranean organic-rich layers
The eastern Mediterranean sapropels are among the most intensively investigated phenomena in the paleoceanographic record, but relatively little has been written regarding the origin of the equivalent of the sapropels in the western Mediterranean, the organic-rich layers (ORLs). ORLs are recognized as sediment layers containing enhanced total organic carbon that extend throughout the deep basins of the western Mediterranean and are associated with enhanced total barium concentration and a reduced diversity (dysoxic but not anoxic) benthic foraminiferal assemblage. Consequently, it has been suggested that ORLs represent periods of enhanced productivity coupled with reduced deep ventilation, presumably related to increased continental runoff, in close analogy to the sapropels. We demonstrate that despite their superficial similarity, the timing of the deposition of the most recent ORL in the Alboran Sea is different than that of the approximately coincident sapropel, indicating that there are important differences between their modes of formation. We go on to demonstrate, through physical arguments, that a likely explanation for the origin of the Alboran ORLs lies in the response of the western Mediterranean basin to a strong reduction in surface water density and a shoaling of the interface between intermediate and deep water during the deglacial period. Furthermore, we provide evidence that deep convection had already slowed by the time of Heinrich Event 1 and explore this event as a potential agent for preconditioning deep convection collapse. Important differences between Heinrich-like and deglacial-like influences are highlighted, giving new insights into the response of the western Mediterranean system to external forcing
Frequentist Analysis of the Parameter Space of Minimal Supergravity
We make a frequentist analysis of the parameter space of minimal supergravity
(mSUGRA), in which, as well as the gaugino and scalar soft
supersymmetry-breaking parameters being universal, there is a specific relation
between the trilinear, bilinear and scalar supersymmetry-breaking parameters,
A_0 = B_0 + m_0, and the gravitino mass is fixed by m_{3/2} = m_0. We also
consider a more general model, in which the gravitino mass constraint is
relaxed (the VCMSSM). We combine in the global likelihood function the
experimental constraints from low-energy electroweak precision data, the
anomalous magnetic moment of the muon, the lightest Higgs boson mass M_h, B
physics and the astrophysical cold dark matter density, assuming that the
lightest supersymmetric particle (LSP) is a neutralino. In the VCMSSM, we find
a preference for values of m_{1/2} and m_0 similar to those found previously in
frequentist analyses of the constrained MSSM (CMSSM) and a model with common
non-universal Higgs masses (NUHM1). On the other hand, in mSUGRA we find two
preferred regions: one with larger values of both m_{1/2} and m_0 than in the
VCMSSM, and one with large m_0 but small m_{1/2}. We compare the probabilities
of the frequentist fits in mSUGRA, the VCMSSM, the CMSSM and the NUHM1: the
probability that mSUGRA is consistent with the present data is significantly
less than in the other models. We also discuss the mSUGRA and VCMSSM
predictions for sparticle masses and other observables, identifying potential
signatures at the LHC and elsewhere.Comment: 18 pages 27 figure
A model of parity-dependent immunity to placental malaria
C1 - Journal Articles RefereedPlasmodium falciparum placental infection during pregnancy is harmful for both mother and child. Protection from placental infection is parity-dependent, that is, acquired over consecutive pregnancies. However, the infection status of the placenta can only be assessed at delivery. Here, to better understand the mechanism underlying this parity-dependence, we fitted a model linking malaria dynamics within the general population to observed placental histology. Our results suggest that immunity resulting in less prolonged infection is a greater determinant of the parity-specific patterns than immunity that prevents placental sequestration. Our results also suggest the time when maternal blood first flows into the placenta is a high-risk period. Therefore, preventative strategies implementable before or early in pregnancy, such as insecticide-treated net usage in women of child-bearing age or any future vaccine, could substantially reduce the number of women who experience placental infection
