A comparative study of two agamid lizards, Laudakia stellio and Pseudotrapelus sinaitus, in southern Sinai
The study compared habitat use and behaviour in two sympatric species of agamid lizard, Laudakia stellio and Pseudotrapelus sinaitus. Despite sharing the same habitat, the two species differed in their utilisation of microhabitats within it. Pseudotrapelus spent significantly longer on rocks compared to Laudakia. Pseudotrapelus showed evidence of heliothermic regulation, spending most of the time in the sun, but moving into the shade in the warmer afternoons. These varying temporal patterns may reflect differential thermoregulatory requirements between the two lizard species. Pseudotrapelus can change colour rapidly. There was no evidence of any thermoregulatory function in this ability; it is likely to be a form of social communication. Being brightly coloured was associated with behaviours implying increased conspicuousness: blue lizards were alert and vigilant for an average of 93% of each viewing session, compared to just 60% of the time in non-blue camouflaged lizards. The striking nature of the transitory blue colouration suggests it may have evolved for maximum salience, a trait common with signals. We simulated social encounters using blue model lizards and mirrors. Behavioural responses to these stimuli all involved colour changes, and support the social-signaling hypothesis
Culturally valuable minority crops provide a succession of floral resources for flower visitors in traditional orchard gardens
Agricultural intensification typically has detrimental effects on pollinator communities, but diverse cropping systems that contain sequentially-flowering crops have the potential to benefit pollinators through the provision of additional floral resources. In this study we investigate the importance of cultivated flora for flower visitors in ten agricultural gardens in South Sinai, Egypt. Insect-flower interactions in gardens and unmanaged plots were surveyed across a four-month period in two environmentally distinct years (pre-flood and post-flood). Despite containing an equal abundance and diversity of wild plants as unmanaged habitat, gardens supported a higher abundance and diversity of flower visitors due to the additional presence of cultivated flora. Visitation networks exhibited dramatic intra-annual changes in composition, with cultivated plants becoming increasingly important in later months. Trends were highly conserved across 2 years despite highly contrasting rainfall. Several key crop species were strongly involved in shaping the structure of the networks, the majority of which were herbs with strong cultural significance (fennel, rosemary, mint) and grown incidentally alongside the primary orchard crops. Minority crops are frequently overlooked in agricultural systems due to their low economic value, but we show that they can have a dramatic influence upon the structure of visitation networks, increasing both pollinator abundance and diversity, and emphasising the link between cultural practices and biodiversity conservation
Traces of violence: Representing the atrocities of war
This article explores the relationships between war and representation through the use of visual images, and takes a cue from the French cultural theorist Paul Virilio, who has written extensively on the militarization of vision in ways that have yet to be fully recognized in criminology. It then outlines some of the disputes surrounding documentary photography, not least since one of the main factors driving the development of the medium was the desire to record warfare, before turning to recent efforts to reconfigure the violence of representation by focusing on what has been termed âaftermath photographyâ, where practitioners deliberately adopt an anti-reportage position, slowing down the image-making process and arriving well after the decisive moment. This more contemplative strategy challenges the oversimplification of much photojournalism and the article concludes by reflecting on how military-turned-consumer technologies are structuring our everyday lives in more and more pervasive ways
Are community forestry principles at work in Ontarioâs County, Municipal, and Conservation Authority forests?
Ontarioâs County, Municipal and Conservation Authority forests have received little attention within the academic literature on community forestry in Canada. These âAgreement Forestsâ, as they were once called, are a product of the early 20th
century and have been under local government management since the 1990s. Most are situated in Southern Ontario. In this article we investigate the extent to which community forestry principles are at work in these forests. Three principlesâparticipatory governance, local benefits and multiple forest useâare analyzed using a composite score approach
derived from survey data collected from nearly all of these forest organizations (response rate = 80%). Results indicate that most of these organizations do display attributes associated with community forestry principles, including a local governance process, public participation activities, local employment and multiple-use management. Traditional forestry employment is less strong than in similar studies of Crown land community forests; however, there is an important emphasis on non-timber activities. The article concludes that the County, Municipal and Conservation Authority forests represents a unique approach, which reflects the specific geographic and socio-economic context in which it resides. / Les forĂȘts cantonales, municipales et des offices de conservation de lâOntario nâont reçu quâune faible couverture dans la littĂ©rature scientifique sur la foresterie communautaire au Canada. Ces « forĂȘts dâentente (Agreement Forests) », comme on
les appelait avant, ont Ă©tĂ© crĂ©Ă©es au dĂ©but du XXe siĂšcle et gĂ©rĂ©es par les autoritĂ©s locales depuis les annĂ©es 1990. La majeure partie de ces forĂȘts sont situĂ©es dans le sud de lâOntario. Dans cet article, nous cherchons Ă voir jusquâĂ quel point les principes de foresterie communautaire sont mis en application dans ces forĂȘts. LâĂ©tude porte sur trois principes â la gouvernance participative, les bĂ©nĂ©fices locaux et lâutilisation polyvalente de la forĂȘt â qui furent analysĂ©s avec lâapproche de rĂ©sultats combinĂ©s utilisant les donnĂ©es dâun sondage effectuĂ© auprĂšs de presque toutes ces organisations forestiĂšres
(taux de réponse = 80 %). Les résultats indiquent que la plupart de ces organisations présentent effectivement certains attributs rappelant les principes de la foresterie communautaire, incluant un processus de gouvernance locale, des activités
de participation du public, lâembauche locale et lâamĂ©nagement Ă des fins dâutilisation polyvalente. Les emplois forestiers traditionnels ont moins dâimportance que dans les Ă©tudes similaires des forĂȘts communautaires Ă©tablies sur des terres publiques; par contre, on accorde beaucoup dâimportance aux activitĂ©s sans prĂ©lĂšvement de bois. Lâarticle conclut que les forĂȘts cantonales, municipales et des offices de conservation constituent une approche unique qui reflĂšte bien le contexte gĂ©ographique et socio-Ă©conomique spĂ©cifique dans lequel elles sont Ă©tablies.Financial support from the Fonds quĂ©bĂ©cois de la recherchĂ© sur la sociĂ©tĂ© et la culture and the Social Sciences and Humanities Research Council.http://pubs.cif-ifc.org/doi/10.5558/tfc2012-13
Watchfully checking rapport with the Primary Child Health Care nurses - a theoretical model from the perspective of parents of foreign origin
<p>Abstract</p> <p>Background</p> <p>Worldwide, multicultural interaction within health care seems to be challenging and problematic. This is also true among Primary Child Health Care nurses (PCHC nurses) in the Swedish Primary Child Health Care services (PCHC services). Therefore, there was a need to investigate the parents' perspective in-depth.</p> <p>Aim</p> <p>The aim of the study was to construct a theoretical model that could promote further understanding of the variety of experiences of parents of foreign origin regarding their interaction with the PCHC nurses at PCHC services.</p> <p>Method</p> <p>The study used Grounded Theory Methodology. Twenty-one parents of foreign origin in contact with PCHC servicies were interviewed.</p> <p>Results</p> <p>In our study parents were watchfully checking rapport, i.e. if they could perceive sympathy and understanding from the PCHC nurses. This was done by checking the nurse's demeanour and signs of judgement. From these interviews we created a theoretical model illustrating the interactive process between parents and PCHC nurses.</p> <p>Conclusion</p> <p>We found it to be of utmost importance for parents to be certain that it was possible to establish rapport with the PCHC nurse. If not, disruptions in the child's attendance at PCHC services could result. PCHC nurses can use the theoretical model resulting from this study as a basis for understanding parents, avoiding a demeanour and judgements that may cause misunderstandings thus promoting high-quality interaction in PCHC services.</p
A qualitative study of patients' views on quality of primary care consultations in Hong Kong and comparison with the UK CARE Measure
<b>Background</b> Patients' priorities and views on quality care are well-documented in Western countries but there is a dearth of research in this area in the East. The aim of the present study was to explore Chinese patients' views on quality of primary care consultations in Hong Kong and to compare these with the items in the CARE measure (a process measure of consultation quality widely used in the UK) in order to assess the potential utility of the CARE measure in a Chinese population.<p></p>
<b>Methods</b> Individual semi-structured interviews were conducted on 21 adult patients from 3 different primary care clinics (a public primary healthcare clinic, a University health centre, and a private family physician's clinic). Topics discussed included expectations, experiences, and views about quality of medical consultations. Interviews were typed verbatim, and a thematic approach was taken to identify key issues. These identified issues were then compared with the ten CARE measure items, using a CARE framework: Connecting (Care Measure items 1â3), Assessing (item 4), Responding (items 5,6), and Empowering (items 7â10).<p></p>
<b>Results</b> Patients judged doctors in terms of both the process of the consultation and the perceived outcomes. Themes identified that related to the interpersonal process of the consultation fitted well under the CARE framework; Connecting and communicating (18/21 patients), Assessing holistically (10/21 patients), Responding (18/21 patients) and Empowering (19/21 patients). Patients from the public clinic, who were generally of lower socio-economic status, were least likely to expect holistic care or empowerment. Two-thirds of patients also judged doctors on whether they performed an adequate physical examination, and three-quarters on the later outcomes of consultation (in terms of relief or cure and/or side-effects of prescribed drugs).<p></p>
<b>Conclusion</b> These findings suggest that Chinese patients in Hong Kong value engaged, empathic primary care doctors and judge the quality of consultations largely on these human skills and the attitudes and values that underpin them, as well as on the perceived outcomes of treatment. The match between themes relating to consultation process and the CARE Measure items suggests utility of this measure in this population, but further quantitative validation is required
Ultrafast laser micro-nano structuring of transparent materials with high aspect ratio
Ultrafast lasers are ideal tools to process transparent materials because
they spatially confine the deposition of laser energy within the material's
bulk via nonlinear photoionization processes. Nonlinear propagation and
filamentation were initially regarded as deleterious effects. But in the last
decade, they turned out to be benefits to control energy deposition over long
distances. These effects create very high aspect ratio structures which have
found a number of important applications, particularly for glass separation
with non-ablative techniques. This chapter reviews the developments of
in-volume ultrafast laser processing of transparent materials. We discuss the
basic physics of the processes, characterization means, filamentation of
Gaussian and Bessel beams and provide an overview of present applications
How effective are on-farm conservation land management strategies for preserving ecosystem services in developing countries? A systematic map protocol
Background
An extensive body of literature in the field of agro-ecology claims to show the positive effects that maintenance of ecosystem services can have on sustainably meeting future food demand, by making farms more productive and resilient, and contributing to better nutrition and livelihoods of farmers. In Africa alone, some research has estimated a two-fold yield increase if food producers capitalize on new and existing knowledge from science and technology. Site-specific strategies adopted with the aim of improving ecosystem services may incorporate principles of multifunctional agriculture, sustainable intensification and conservation agriculture. However, a coherent synthesis and review of the evidence of these claims is largely absent, and the quality of much of this literature is questionable. Moreover, inconsistent effects have commonly been reported, while empirical evidence to support assumed improvements is largely lacking.
Objectives
This systematic map is stimulated by an interest to (1) collate evidence on the effectiveness of on-farm conservation land management for preserving and enhancing ecosystem services in agricultural landscapes, by drawing together the currently fragmented and multidisciplinary literature base, and (2) geographically map what indicators have been used to assess on-farm conservation land management. For both questions, we will focus on 74 low-income and developing countries, where much of the worldâs agricultural expansion is occurring, yet 80% of arable land is already used and croplands are yielding well below their potential.
Methods/Design
To this end, reviewers will systematically search bibliographic databases for peer-reviewed research from Web of Science, SCOPUS, AGRICOLA, AGRIS databases and CAB abstracts, and grey literature from Google Scholar, and 22 subject-specific or institutional websites. Boolean search operators will be used to create search strings where applicable. Ecosystem services included in the study are pollination services; pest-, carbon-, soil-, and water-regulation; nutrient cycling; medicinal and aromatic plants; fuel wood and cultural services. Outputs of the systematic map will include a database, technical report and an online interactive map, searchable by topic. The results of this map are expected to provide clarity about synergistic outcomes of conservation land management, which will help support local decision-making
