Psychology Students’ Beliefs about Integrating Complementary and Alternative Therapy (CAT) into Their Future Psychology Practice  [PDF]
Lee-Ann M. Wilson, Kyra Hamilton, Katherine M. White
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.32029
Abstract: We investigated whether belief-based differences exist between students who have strong and weak intentions to integrate complementary and alternative therapy (CAT) into future psychology practice by recommending CAT or specific CAT practitioners to clients. A cross-sectional methodology was used. Psychology undergraduate students (N = 106) participated in a paper-based questionnaire design to explore their underlying beliefs related to CAT integration. The study was undertaken at a major university in Queensland, Australia. The theory of planned behaviour belief-based framework guided the study. Multivariate analyses of variance examined the influence of behavioural, normative, and control beliefs on the strong and weak intention groups. A multiple regression analysis investigated the relative importance of these belief sets for predicting intentions. We found that clear differences emerged between strong and weak intenders on behavioural and normative beliefs, but not control beliefs. Strong intenders perceived the positive outcomes of integrating CAT, such as being able to offer clients a more holistic practice and having confidence in the practitioners/practices, as more likely to occur than weak intenders, and perceived the negative outcome of compromising my professional practice as less likely. Strong intenders were more likely than weak intenders to perceive that a range of important referents (e.g., clients) would think they should integrate CAT. Results of the regression analysis revealed the same pattern of results in that behavioural and normative beliefs, but not control beliefs, significantly predicted intentions. The findings from this study can be used to inform policy and educational initiatives that aim to encourage CAT use in psychology practice.

BMC Public Health , 2009, DOI: 10.1186/1471-2458-9-76
Abstract: HABITAT is a longitudinal multi-level study. 1625 Census Collection Districts (CCDs) in Brisbane, Australia were ranked by their index of relative socioeconomic disadvantage score, categorized into deciles, and 20 CCDs from each decile were selected to provide 200 local areas for study inclusion. From each of the 200 CCDs, dwellings with individuals aged between 40–65 years (in 2007) were identified using electoral roll data, and approximately 85 people per CCD were selected to participate (N = 17,000). A comprehensive Geographic Information System (GIS) database has been compiled with area-level information on public transport networks, footpaths, topography, traffic volume, street lights, tree coverage, parks, public services, and recreational facilities Participants are mailed a questionnaire every two years (2007, 2009, 2011), with items assessing physical activity (general walking, moderate activity, vigorous activity, walking for transport, cycling for transport, recreational activities), sitting time, perceptions of neighborhood characteristics (traffic, pleasant surroundings, streets, footpaths, crime and safety, distance to recreational and business facilities), social support, social cohesion, activity-related cognitions (attitudes, efficacy, barriers, motivation), health, and sociodemographic characteristics. Analyses will use binary and multinomial logit regression models, as well as generalized linear latent growth models.HABITAT will provide unique information to improve our understanding of the determinants of physical activity, and to help identify "people" and "place" priority targets for public policy and health promotion aimed at increasing physical activity participation among mid-aged men and women.To promote and maintain health, it is recommended that adults do moderate intensity exercise for at least 30 minutes on five days each week, or vigorous intensity activity for at least 20 minutes on three days each week, or a combination of these [1].
Quantifying Assemblage Turnover and Species Contributions at Ecologic Boundaries
Lee-Ann C. Hayek, Brent Wilson
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0074999
Abstract: Not all boundaries, whether stratigraphical or geographical, are marked by species-level changes in community composition. For example, paleodata for some sites do not show readily discernible glacial-interglacial contrasts. Rather, the proportional abundances of species can vary subtly between glacials and interglacials. This paper presents a simple quantitative measure of assemblage turnover (assemblage turnover index, ATI) that uses changes in species' proportional abundances to identify intervals of community change. A second, functionally-related index (conditioned-on-boundary index, CoBI) identifies species contributions to the total assemblage turnover. With these measures we examine benthonic foraminiferal assemblages to assess glacial/interglacial contrasts at abyssal depths. Our results indicate that these measures, ATI and CoBI, have potential as sequence stratigraphic tools in abyssal depth deposits. Many peaks in the set of values of ATI coincide with terminations at the end of glaciations and delineate peak-bounded ATI intervals (PATIs) separated by boundaries that approximate to glacial terminations and to transgressions at neritic depths. These measures, however, can be used to evaluate the assemblage turnover and composition at any defined ecological or paleoecological boundary.

Stage-Specific Pathways of Leishmania infantum chagasi Entry and Phagosome Maturation in Macrophages
Nilda E. Rodríguez,Upasna Gaur Dixit,Lee-Ann H. Allen,Mary E. Wilson
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0019000
Abstract: The life stages of Leishmania spp. include the infectious promastigote and the replicative intracellular amastigote. Each stage is phagocytosed by macrophages during the parasite life cycle. We previously showed that caveolae, a subset of cholesterol-rich membrane lipid rafts, facilitate uptake and intracellular survival of virulent promastigotes by macrophages, at least in part, by delaying parasitophorous vacuole (PV)-lysosome fusion. We hypothesized that amastigotes and promastigotes would differ in their route of macrophage entry and mechanism of PV maturation. Indeed, transient disruption of macrophage lipid rafts decreased the entry of promastigotes, but not amastigotes, into macrophages (P<0.001). Promastigote-containing PVs were positive for caveolin-1, and co-localized transiently with EEA-1 and Rab5 at 5 minutes. Amastigote-generated PVs lacked caveolin-1 but retained Rab5 and EEA-1 for at least 30 minutes or 2 hours, respectively. Coinciding with their conversion into amastigotes, the number of promastigote PVs positive for LAMP-1 increased from 20% at 1 hour, to 46% by 24 hours, (P<0.001, Chi square). In contrast, more than 80% of amastigote-initiated PVs were LAMP-1+ at both 1 and 24 hours. Furthermore, lipid raft disruption increased LAMP-1 recruitment to promastigote, but not to amastigote-containing compartments. Overall, our data showed that promastigotes enter macrophages through cholesterol-rich domains like caveolae to delay fusion with lysosomes. In contrast, amastigotes enter through a non-caveolae pathway, and their PVs rapidly fuse with late endosomes but prolong their association with early endosome markers. These results suggest a model in which promastigotes and amastigotes use different mechanisms to enter macrophages, modulate the kinetics of phagosome maturation, and facilitate their intracellular survival.

Abstract: We examined two measures of traffic: distance to nearest road and number of roads around the home. To examine the effect of distance we used the number of roads around the home in radii from 50 to 500 metres. We examined three road types: freeways, highways and main roads.There were no associations with distance to road. A greater number of freeways and main roads around the home were associated with a shorter gestation time. There were no negative impacts on birth weight, birth length or head circumference after adjusting for gestation. The negative effects on gestation were largely due to main roads within 400 metres of the home. For every 10 extra main roads within 400 metres of the home, gestation time was reduced by 1.1% (95% CI: -1.7, -0.5; p-value = 0.001).Our results add weight to the association between exposure to traffic and reduced gestation time. This effect may be due to the chemical toxins in traffic pollutants, or because of disturbed sleep due to traffic noise.Exposure to air pollution during pregnancy has been shown to increase the risk of negative birth outcomes such as pre-term birth and low birth weight [1-4]. Although the increased risks are relatively small [5-7], the public health implications are large because exposure to some level of air pollution is ubiquitous in urban areas, and pre-term and low weight babies: stay in hospital longer after birth, have an increased risk of death, and are more likely to develop disabilities [8-10].Many of the estimated associations between air pollution and birth outcomes have relied on the temporal variation in pollution, but pollution also varies spatially [11]. Pollution levels in a city are generally higher in areas with lots of traffic and industrial areas. Temporal studies also rely on a fixed network of pollution monitors, and these monitors can often be far from subjects' homes. Ignoring the spatial variability in pollution therefore introduces a measurement error that may lead to regression diluti
Neutrophils: potential therapeutic targets in tularemia?
Lee-Ann H. Allen
Frontiers in Cellular and Infection Microbiology , 2013, DOI: 10.3389/fcimb.2013.00109
Abstract: The central role of neutrophils in innate immunity and host defense has long been recognized, and the ability of these cells to efficiently engulf and kill invading bacteria has been extensively studied, as has the role of neutrophil apoptosis in resolution of the inflammatory response. In the past few years additional immunoregulatory properties of neutrophils were discovered, and it is now clear that these cells play a much greater role in control of the immune response than was previously appreciated. In this regard, it is noteworthy that Francisella tularensis is one of relatively few pathogens that can successfully parasitize neutrophils as well as macrophages, DC and epithelial cells. Herein we will review the mechanisms used by F. tularensis to evade elimination by neutrophils. We will also reprise effects of this pathogen on neutrophil migration and lifespan as compared with other infectious and inflammatory disease states. In addition, we will discuss the evidence which suggests that neutrophils contribute to disease progression rather than effective defense during tularemia, and consider whether manipulation of neutrophil migration or turnover may be suitable adjunctive therapeutic strategies.
Determining sexual dimorphism in frog measurement data: integration of statistical significance, measurement error, effect size and biological significance
Hayek, Lee-Ann C.;Heyer, W. Ronald;
Anais da Academia Brasileira de Ciências , 2005, DOI: 10.1590/S0001-37652005000100005
Abstract: several analytic techniques have been used to determine sexual dimorphism in vertebrate morphological measurement data with no emergent consensus on which technique is superior. a further confounding problem for frog data is the existence of considerable measurement error. to determine dimorphism, we examine a single hypothesis (ho = equal means) for two groups (females and males). we demonstrate that frog measurement data meet assumptions for clearly defined statistical hypothesis testing with statistical linear models rather than those of exploratory multivariate techniques such as principal components, correlation or correspondence analysis. in order to distinguish biological from statistical significance of hypotheses, we propose a new protocol that incorporates measurement error and effect size. measurement error is evaluated with a novel measurement error index. effect size, widely used in the behavioral sciences and in meta-analysis studies in biology, proves to be the most useful single metric to evaluate whether statistically significant results are biologically meaningful. definitions for a range of small, medium, and large effect sizes specifically for frog measurement data are provided. examples with measurement data for species of the frog genus leptodactylus are presented. the new protocol is recommended not only to evaluate sexual dimorphism for frog data but for any animal measurement data for which the measurement error index and observed or a priori effect sizes can be calculated.

Abstract: In diesem Beitrag geht es um die Erinnerungen und biografischen Narrationen lterer lesbischer Frauen und schwuler M nner zu ihren Erfahrungen mit dem Landleben in Gro britannien und um eine Reflexion der unterschiedlichen qualitativen Verfahren, die in einem partizipativen Handlungsforschungsprojekt zum Einsatz kamen. Ziel des Projektes war das Empowerment lterer lesbischer Frauen und schwuler M nner in l ndlichen Gegenden im Rahmen eines kollaborativen Designs und durch eine m glichst weitgehende Einbindung in den Forschungsprozess selbst.<>Zu den Methoden, die genutzt wurden, geh ren die biografisch-narrative interpretative Methode (BNIM) (JONES, 2001, 2004; WENGRAF, 2001), visuell-ethnografische Erhebungen, eine Fokusgruppe und eine zweit gige künstlerische Improvisation. Mit Blick auf die Verbreitung der Forschungsergebnisse folgte das Projekt den Prinzipien performativer Sozialwissenschaft (GERGEN & JONES, 2008; JONES, 2006, 2012a, 2012b). Vier der erhobenen Lebensgeschichten werden in dem Artikel pr sentiert. Diese Geschichten haben zusammen mit anderen Narrationen, Berichten und Beobachtungsmaterial Eingang in das Hauptergebnis des Projektes gefunden, den Kurzfilm Rufus Stone. Der Film zielt darauf, den Dialog zwischen unterschiedlichen Beteiligten zu f rdern und auch Dienstleistungseinrichtungen über die Bedürfnisse dieser spezifischen Gruppen zu informieren, um so auf Mikro- und Makroebene neue M glichkeiten der Verbundenheit, Kommunikation und Gemeinschaftlichkeit zu er ffnen. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs130275 The emerging recollections, perceptions and storied biographies of older lesbians and gay men and their experiences in rural Britain are presented in the article, alongside consideration of the multiple qualitative methodologies used in a unique multi-method participatory action research project. The project aimed to empower older lesbians and gay men in rural areas through a collaborative design and meaningful participation in the research process itself. Methods included the core Biographic Narrative Interpretive Method (BNIM) (JONES, 2001, 2004; WENGRAF, 2001) with its interpretation of data by panels of citizens. In addition, visual ethnographic site visits, a focus group and two days of theatrical improvisation of interview data to explore action within the texts were used. The project embraced the principles of a performative social science (GERGEN & JONES, 2008; JONES, 2006, 2012) in its dissemination plan. Four of the collected stories are elaborated on here. These and other stories, reports and observations
Construct validity of competency dimensions in a team leader assessment centre
Lee-Ann Greyling,Deléne Visser,Linda Fourie
South African Journal of Industrial Psychology , 2003, DOI: 10.4102/sajip.v29i2.97
Abstract: The aim of the study was to examine the construct validity of an assessment centre. The sample included 138 individuals who participated in a one-day call centre team leader assessment centre. Nine competency dimensions were rated using six exercises. Correlations and a principle axis factor analysis were utilised to study the convergent and discriminant validity of the dimension ratings. The results showed that the ratings clustered according to exercises rather than to dimensions (traits), thereby indicating a substantial amount of method variance. A further factor analysis of the nine competency dimensions yielded two factors that were named interpersonal and problem solving. Implications for the design of assessment centres are discussed. Opsomming Die doel van die studie was om die konstrukgeldigheid van ’n takseersentrum te ondersoek. Die steekproef het uit 138 persone bestaan wat aan ’n eendagtakseersentrum vir oproepsentrumgroepleiers deelgeneem het. Ses oefeninge is gebruik om nege bevoegdheidsdimensies te meet. Korrelasies en ’n hoofasfaktorontleding is gebruik om die konvergente en diskriminante geldigheid van die dimensiebeoordelings te bestudeer. Die resultate het getoon dat die beoordelings volgens oefeninge eerder as dimensies (eienskappe) gegroepeer het. Hierdie bevinding dui op ’n ho mate van metodevariansie. ’n Verdere faktorontleding van die nege bevoegdheidsdimensies het twee faktore, wat as interpersoonlik en probleemoplossend benoem is, opgelewer. Implikasies vir die ontwerp van takseersentrums word bespreek.
