WHOQOL-BREF as a measure of quality of life in older patients with depression

Objective: To assess the reliability and validity of a brief measure of quality of life recently developed by the World Health Organization, the WHOQOL-BREF, and to examine its association with a variety of clinical and sociodemographic factors in older depressed patients. Design: Cross-sectional study. Methods: Older depressed patients (N=41) underwent diagnostic assessment using the Composite International Diagnostic Interview (CIDI) and were independently assessed on a variety of measures including the WHOQOL-BREF (a 26-item self-report questionnaire generating four domain scores), Hamilton Depression Rating Scale (HAM-D); Geriatric Depression Scale (GDS); Mini-mental State Examination (MMSE); Modified Barthel Index (MBI); Instrumental activities of daily living (IADL), and measures of physical health status and social relationships. Estimates of inter-rater and test-retest reliability, and concurrent validity were made. Results: 39 subjects completed the study. The majority of subjects (94.9%) received a diagnosis of DSM-IV Major Depressive Disorder. Levels of comorbidity were high. Three of the four domains of the WHOQOL-BREF (Physical, Psychological and Environment domains) demonstrated satisfactory reliability and validity. However, the Social Relationships domain exhibited poor validity. Quality of life scores were strongly correlated with severity of depression, number of self-reported physical symptoms and self-assessed general health status. There was no relationship between diagnostic comorbidity and quality of life scores. Conclusions: The WHOQOL-BREF was successfully administered to older depressed patients although the concurrent validity of one of its four domains was poor. Quality of life scores were strongly correlated with severity of depression, raising the issue of measurement redundancy.

Drinking refusal self-efficacy questionnaire-revised (DRSEQ-R): a new factor structure with confirmatory factor analysis

The drinking refusal self-efficacy questionnaire (DRSEQ: Young, R.M., Oei, T.P.S., 1996. Drinking expectancy profile: test manual. Behaviour Research and Therapy Centre, University of Queensland, Australia Young, R.M., Oei, T.P.S., Crook, G.M., 1991. Development of a drinking refusal self-efficacy questionnaire. J. Psychopathol. Behav. Assess., 13, 1-15) assesses a person's belief in their ability to resist alcohol. The DRSEQ is a sound psychometric instrument based on exploratory factor analyses, but has not been subjected to confirmatory factor analysis. In total 2773 participants were used to confirm the factor structure of the DRSEQ. Initial analyses revealed that the original structure was not confirmed in the current study. Subsequent analyses resulted in a revised factor structure (DRSEQ-R) being confirmed in community, student and clinical samples. The DRSEQ-R was also found to have good construct and concurrent validity. The factor structure of the DRSEQ-R is more stable than the original structure of the DRSEQ and the revised scale has considerable potential in future alcohol-related research.

Two-tone intermodulation tests were simulated for an amplitude modulated radio-on-fibre link including fibre dispersion, nonlinearity and loss. The third-order intercept results are presented for varying fibre lengths and optical transmission powers.

Auditory grouping in cochlear implant listeners

This thesis describes a series of experiments investigating both sequential and concurrent auditory grouping in implant listeners. Some grouping cues used by normal-hearing listeners should also be available to implant listeners, while others (e.g. fundamental frequency) are unlikely to be useful. As poor spectral resolution may also limit implant listeners’ performance, the spread of excitation in the cochlea was assessed using Neural Response Telemetry (NRT) and the results were related to those of the perceptual tasks. Experiment 1 evaluated sequential segregation of alternating tone sequences; no effect of rate or evidence of perceptual ambiguity was found, suggesting that automatic stream segregation had not occurred. Experiment 2 was an electrode pitch-ranking task; some relationship was found between pitch-ranking judgements (especially confidence scores) and reported segregation. Experiment 3 used a temporal discrimination task; this also failed to provide evidence of automatic stream segregation, because no interaction was found between the effects of sequence length and electrode separation. Experiment 4 explored schema-based grouping using interleaved melody discrimination; listeners were not able to segregate targets and distractors based on pitch differences, unless accompanied by substantial level differences. Experiment 5 evaluated concurrent segregation in a task requiring the detection of level changes in individual components of a complex tone. Generally, large changes were needed and abrupt changes were no easier to detect than gradual ones. In experiment 6, NRT testing confirmed substantially overlapping simulation by intracochlear electrodes. Overall, little or no evidence of auditory grouping by implant listeners was found.

Policy transfer in practice:implementing supplier diversity in the UK

This article draws on the policy transfer literature to examine a UK-based initiative to promote supplier diversity and provides insights into three areas neglected in current research, namely: the dynamics of non-governmental policy transfer; the factors that mediate policy transfer in different jurisdictions; and the integration of research and practice in small business related policy transfer. To this end, an innovative action research approach is deployed with the dual purpose of effecting practical change and advancing knowledge. This comprises two phases: first, a realist analysis of the US National Minority Supplier Development Council (NMSDC), an exemplar intermediary; and second, the implementation and concurrent realist evaluation of a supplier diversity initiative modelled on NMSDC, referred to as ‘Supplier Development East Midlands’ (SDEM). The findings provide lessons for academics and practitioners dealing with small and medium-sized enterprise (SME) policy transfer in general and supplier diversity intermediaries in particular.

Developing Agent Interaction Protocols with PRALU

The purpose of the paper is to explore the possibility of applying existing formal theories of description and design of distributed and concurrent systems to interaction protocols for real-time multi-agent systems. In particular it is shown how the language PRALU, proposed for description of parallel logical control algorithms and rooted in the Petri net formalism, can be used for the modeling of complex concurrent conversations between agents in a multi-agent system. It is demonstrated with a known example of English auction on how to specify an agent interaction protocol using considered means.

The career development of Black female chief nurse executives

This qualitative study was designed to explore the career development of Black female chief nurse executives. Although a small proportion of Black female nurses have achieved positions at the nurse executive level, there remains a paucity of Black female nurse executives in this crucial position which raised the question of what factors contributed to this lack of advancement, but, more important, what factors have contributed to the success of the few who have achieved such level of success in healthcare organizations. The purpose of the study was to explore the career paths of Black female chief nurse executives with a view of understanding the factors which both facilitate and hinder the career development of these leaders in healthcare organizations. The guiding research question was, How do Black female nurse executives in this sample describe their career development? The participants in this study were Black female chief nurse executives located throughout the United States who, for the most part, were raised in segregation with a strong family foundation. To collect data, semistructured telephone interviews were conducted with 10 Black female chief nurse executives throughout the United States. The transcripts from the interviews were transcribed, coded, and analyzed. Using Super’s (1990, 1996), and Gottfredson’s (1981, 1996, 2002, 2005) career development theories and critical race theory (Crenshaw, 1995; Delgado, 2000) as the theoretical framework, the researcher found that the participants’ career development was influenced by (a) strong support system, (b) guidance, (c) influence of diversity, and (d) servant leadership. The findings help us understand the factors that have contributed to their successes as Black chief nurse executives. With the increasingly diverse population and concurrent increasing diversity in nursing and concerns about healthcare disparities, it is imperative that organizations attract, hire, develop, retain, and advance qualified Black nurses. Future studies addressing not only the career development of Black nurses but nurses in general might be informed by the present study’s findings. Recommendations are offered for nursing practice, education, and organizational policy.

China's Building of a Blue-Water Fleet

In recent years the People’s Republic of China has begun to exhibit a more aggressive naval policy as a result of its decision to switch its naval force from a primarily green-water fleet (coastal) to a blue-water fleet (expeditionary) (“China’s New,” n.d.). This decision has brought China to loggerheads not only with other local East and South Asian powers such as India and Japan, but also with the predominant blue-water power of the world, the United States, that sees its supremacy threatened (“When Grand,” n.d.). Why would China embark on a route that would pit it against the world naval superpower, the United States, which has a huge lead on China in terms of naval blue-water power? Why would China try to challenge and match the U.S. Navy’s eleven aircraft carriers (“The World’s,” n.d.)? What could compel China to embark on a plan that would so disrupt the balance of power in the waters around Asia? To fully understand the Chinese government’s decision, one must first look at Chinese import figures and Chinese trade routes.

Da voz que cala ao corpo que fala: o assédio moral no ambiente de trabalho como desafio para o serviço social

The changes ocurred in the world of capitalist labor, especially from the last decades of the 20th century, accentuated the process of manipulation and domination of the working class, materialized mainly through naturalization and / or trivialization of violence, conducted in the work environment. From this process, emerge the elements of bullying, that is, the embarrassing and humiliating practices which extend through time, degrading human race, and becoming fruitful object for study, debate and the intervention of the professionals of the Social Service area. Thus, we assume the perspective of analyzing the concepts and the work of social workers, whom work at people management area before the bullying in the workplace. We propose the following objectives: apprehend the settings of bullying, in the contemporary context of competitiveness and flexibility of work, as well as its implications for workers' health; characterize the background of this expression of violence at work in the municipality of Natal- RN; and analyze the powers and duties of the social worker in the process of prevention, identification and addressing of bullying in the context of work. This study consisted of a qualitative approach, based on the dialectical-critical method as soon as we adopt methodological procedures such as: theoretical knowledge, documental and field research, and performed using semi-structured interviews. The subjects of this research were nine (09) the Social Service professionals working in personnel management area, in five (5) institutions with legal and branches of different activities, located in Natal-RN. Even interviewed one (01) representative of the Public Ministry of Rio Grande do Norte Office (MPT-RN). The findings of this analysis indicate that bullying is a contemporary expression of "social question", which is presented as a demand for the Social-assistants – covered up and / or camuflage – under the guise of problems related to workers' health or mere conflicts of interpersonal relationships, that is, without any causal connection with the organization of work. The fear of losing job, not to be inserted in the labor market, and / or suffering reprisals, deepens the subject levels of the victims of bullying. Hence the importance of Social Workers are capable to understand the social reality, by preventing and combating the elements of bullying.

Mode-locked laser pulse sources for wavelength division multiplexing

Recent theoretical investigations have demonstrated that the stability of mode-locked solution of multiple frequency channels depends on the degree of inhomogeneity in gain saturation. In this paper, these results are generalized to determine conditions on each of the system parameters necessary for both the stability and existence of mode-locked pulse solutions for an arbitrary number of frequency channels. In particular, we find that the parameters governing saturable intensity discrimination and gain inhomogeneity in the laser cavity also determine the position of bifurcations of solution types. These bifurcations are completely characterized in terms of these parameters. In addition to influencing the stability of mode-locked solutions, we determine a balance between cubic gain and quintic loss, which is necessary for existence of solutions as well. Furthermore, we determine the critical degree of inhomogeneous gain broadening required to support pulses in multiple frequency channels. © 2010 Copyright SPIE - The International Society for Optical Engineering.

Dark soliton generation from semiconductor optical amplifier gain medium in ring fiber configuration

We have investigated the mode-lock operation from a semiconductor optical amplifier (SOA) gain chip in the ring fibre configuration. At lower pump currents, the laser generates dark soliton pulses both at the fundamental repetition rate of 39 MHz and supports up to the 6th harmonic order corresponding to 234-MHz repetition rate with an output power of ∼2.1 mW. At higher pump currents, the laser can be switched between the bright, dark and concurrent bright and dark soliton generation regimes.

Studying Recommender Systems to Enhance Distributed Computing Schedulers

Distributed Computing frameworks belong to a class of programming models that allow developers to

launch workloads on large clusters of machines. Due to the dramatic increase in the volume of

data gathered by ubiquitous computing devices, data analytic workloads have become a common

case among distributed computing applications, making Data Science an entire field of

Computer Science. We argue that Data Scientist's concern lays in three main components: a dataset,

a sequence of operations they wish to apply on this dataset, and some constraint they may have

related to their work (performances, QoS, budget, etc). However, it is actually extremely

difficult, without domain expertise, to perform data science. One need to select the right amount

and type of resources, pick up a framework, and configure it. Also, users are often running their

application in shared environments, ruled by schedulers expecting them to specify precisely their resource

needs. Inherent to the distributed and concurrent nature of the cited frameworks, monitoring and

profiling are hard, high dimensional problems that block users from making the right

configuration choices and determining the right amount of resources they need. Paradoxically, the

system is gathering a large amount of monitoring data at runtime, which remains unused.

In the ideal abstraction we envision for data scientists, the system is adaptive, able to exploit

monitoring data to learn about workloads, and process user requests into a tailored execution

context. In this work, we study different techniques that have been used to make steps toward

such system awareness, and explore a new way to do so by implementing machine learning

techniques to recommend a specific subset of system configurations for Apache Spark applications.

Furthermore, we present an in depth study of Apache Spark executors configuration, which highlight

the complexity in choosing the best one for a given workload.
