A method for the quantitative analysis of the layering of HIV-related stigma

HIV-related stigma is regarded as one of the major barriers in the development of effective prevention and care programs; but the stigma associated with HIV stigma is not a singular entity. The stigma of the infection is layered with other stigmas, such as those associated with the routes of transmission (e.g., sex work and injecting drug use) and personal characteristics (e.g., race, religion, ethnicity and gender). In developing programs and policies to overcome HIV-related stigma, cognisance needs to be taken of all the sources of stigma, and how they may interact. A novel method is described for examining the layers of HIV/AIDS-related stigma, and secondary data are adapted to illustrate this. The importance of understanding the layering of stigma for the development of effective interventions is also discussed.

Quantitative analysis of research mediums' consious experiences during a discarnate reading versus a control task : a pilot study

Mediums claim to be able to report accurate and specific information about the deceased loved ones (termed discarnates) of living people (termed sitters) even without any prior knowledge about the sitters or the discarnates and in the complete absence of any sensory feedback. Despite recent proof-focused experimental research investigating this phenomenon (e.g., Beischel & Schwartz, 2007), no published studies have attempted to quantify the phenomenological effects of discarnate readings. The aim of the present study was, thus, to investigate experimentally the phenomenological differences that arose psychologically in accordance with the demands of a discarnate reading task versus a control task. Seven mediums were administered counter-balanced sequences of a discarnate reading and control condition. The discarnate reading condition consisted of a phone reading including questions about a discarnate where only a blinded medium and a blinded experimenter were on the phone. The control condition consisted of a phone conversation between the medium and the same experimenter in which the medium was asked similar questions regarding a living person s/he (i.e., the medium) knew. Mediums’ phenomenology during each condition was retrospectively assessed using the Phenomenology of Consciousness Inventory (PCI). Phenomenology associated with the discarnate reading condition appeared to be significantly different from phenomenology associated with the control condition. Future research might use the PCI to address whether the phenomenology reported by mediums during discarnate readings is quantitatively different from their experiences during psychic telepathy readings for the living.

Qualitative and quantitative analysis of lipid classes in fish oils by thin-layer chromatography with an Iatroscan flame Ionization detector (TLC-FID) and liquid chromatography with an evaporative light scattering detector (LC-ELSD)

Combined effects of hydrogen and air flow rates on the peak response of selected neutral lipid classes (triacylglycerol, diacylglycerol, monoacylglycerol, free fatty acids, and ethyl esters) were studied to optimize and calibrate the Iatroscan Mk-6s Chromarod system for the qualitative and quantitative analysis of lipid classes by thin-layer chromatography (TLC) with flame ionization detection in fish oil during the transesterification process. Air flow rate of 2 L/min, hydrogen flow rate of 150-160 mL/min, and scan rate of 30 s/rod were found to be the optimum conditions. All samples were also analyzed by high performance liquid chromatography (HPLC) with evaporative light scattering detection. Quantitative results obtained by TLC with the flame ionization detection method were comparable to those obtained from HPLC with evaporative light scattering detection.

Government involvement in entrepreneurship and new business creation in Australia : a quantitative analysis of public perceptions and opinions

In order to determine the range of Australian perceptions on new venture creation at the end of the decade of the 1980s, and in particular attitudes towards government involvement in fostering entrepreneurship, a major quantitative study was conducted. The survey involved more than 1500 Australians in face-to-face interviews (300 in each mainland capital city) chosen on a random basis.

An analysis of the data provides an assessment of the Australian general public&s perceptions in three key areas: their understanding of the word 'entrepreneur' their rating of importance of new venture creation; their belief in government involvement in fostering new venture creation.

It is believed to be the first study attempting to quantify an entire nation&s perceptions in three areas vital to creators of national economic and industry policies.

Very high pressure liquid chromatography using fully porous particles: Quantitative analysis of fast gradient separations without post-run times

Using a column packed with fully porous particles, four methods for controlling the flow rates at which gradient elution runs are conducted in very high pressure liquid chromatography (VHPLC) were tested to determine whether reproducible thermal conditions could be achieved, such that subsequent analyses would proceed at nearly the same initial temperature. In VHPLC high flow rates are achieved, producing fast analyses but requiring high inlet pressures. The combination of high flow rates and high inlet pressures generates local heat, leading to temperature changes in the column. Usually in this case a post-run time is input into the analytical method to allow the return of the column temperature to its initial state. An alternative strategy involves operating the column without a post-run equilibration period and maintaining constant temperature variations for subsequent analysis after conducting one or a few separations to bring the column to a reproducible starting temperature. A liquid chromatography instrument equipped with a pressure controller was used to perform constant pressure and constant flow rate VHPLC separations. Six replicate gradient separations of a nine component mixture consisting of acetophenone, propiophenone, butyrophenone, valerophenone, hexanophenone, heptanophenone, octanophenone, benzophenone, and acetanilide dissolved in water/acetonitrile (65:35, v/v) were performed under various experimental conditions: constant flow rate, two sets of constant pressure, and constant pressure operation with a programmed flow rate. The relative standard deviations of the response factors for all the analytes are lower than 5% across the methods. Programming the flow rate to maintain a fairly constant pressure instead of using instrument controlled constant pressure improves the reproducibility of the retention times by a factor of 5, when plotting the chromatograms in time.

The male germ unit of Rhododendron : quantitative cytology, three-dimensional reconstruction, isolation and detection using fluorescent probes

The sperm cells of Rhododendron laetum and R. macgregoriae differentiate within the pollen tube about 24 h after germination in vitro. Threedimensional reconstruction shows that the sperm cells are paired together, and both have extensions that link with the tube nucleus, forming a male germ unit. Quantitative analysis shows that the sperm cells in each pair differ significantly in surface area, but not in cell volume nor in numbers of mitochondria or plastids. When isolated from pollen tubes by osmotic shock, the sperm cells became ellipsoidal and surrounded by their own plasma membrane, while a proportion remained in pairs linked by the inner tube plasma membrane. Both generative and sperm cells are visualized in pollen tube preparations by immunofluorescence with anti-tubulin and anti-actin monoclonal antibodies (MAbs) combined with H33258 fluorescence of the nuclei. Video-image processing shows the presence of an axial microtubule cage in the generative cells, and some microtubules are present in the cytoplasmic extensions that clasp the tube nucleus. Following sperm cell division, the extensive phragmoplast between the sperm nuclei is partitioned by the plasma membranes.

An empirical analysis of the factors affecting bank crises in Japan : learning points for Bangladesh

This paper analyzes the factors that affect bank crises in Japan. There are numerous factors, qualitative and quantitative, identified from the analysis. For the quantitative analysis, the study employs the factor analysis, which detects three major components of factors that affect banking or financial crises in Japan. These are (i) common macro factors; (ii) bank sensitive micro factors; and (iii) household spending related factors. There are other factors, for example, policy dilemma, delayed or faulty deregulation measures and weak banking activities, which are not extracted from the factor analysis but adversely affect bank crises in Japan and hence discussed in details. The paper indicates some policy implications for the banking/financial sector of Bangladesh.

Arts management/marketing journal citation analysis : assessing external impact

Purpose – This paper aims to present a quantitative analysis of arts management/marketing articles in leading general management/marketing journals, including an examination of the extent to which those top tier journal articles on arts/culture-related topics cite authors of leading arts management journal articles.

Design/methodology/approach – Using bibliometric techniques, this study examines the content of 20 top tier management and marketing journals over 22 years to identify articles published on arts management/marketing, which authors were cited, and from which arts management/marketing journals.

Findings – Analysis indicates that: relatively few citations in the top management/marketing journals reference arts management/marketing journals; assessment of interaction between the parent management/marketing disciplines and the arts management/marketing sub-discipline indicates that authors draw upon a large reserve of diverse literatures; and top journal arts-related management/marketing articles tend to utilize citations to journal articles grounded in the social sciences and aesthetics of management, with an increasing trend of citations to arts management/marketing journals.

Research limitations/implications – This study of the extent to which top journals have published arts/culture-related articles and the citation impact of arts management/marketing journals is the initial academic study on the topic and suggests opportunities for further research.

Practical implications – Analysis of arts management/marketing journal impact contributes to professionalization of the field and increased perceived value of those journals by industry practitioners.

Originality/value – This research is the first to examine the spectrum of arts management/marketing literature, including both top general management/marketing journals and sector-oriented arts management/marketing journals, establishing a body of knowledge for augmentation by future research over time.
