Resistance Is Not Futile: Liberating Captain Janeway from the Masculine-Feminine Dualism of Leadership

the boundary between science-fiction and social reality is an optical illusion’ (Haraway, 1990, p. 191) My underlying purpose in this article is to uncover the way in which research on leadership has been constrained by a reliance on the categories male-female and/or masculine-feminine for theorizing and for empirical work. I argue that both gender and leadership are caught within what Judith Butler calls the heterosexual matrix and that this has significant repercussions on leaders and leadership discourse. I use the character of Captain Kathryn Janeway from Star Trek: Voyager as a case study. I begin by analysing her leadership on the television series. I then perform a similar analysis of Janeway as she is represented in a text that subverts her gender by queering her character. I compare the two Janeways and the effect that the construction of each one's gender has on her leadership. In the conclusion I discuss ways in which we can use this analysis to move towards fluidity in the theorizing and practice of both gender and leadership.
‘Dad, Where are we Going to Live Now?’ Exploring Fathers’ Experiences of Homelessness

Abstract In 2003, over 41 000 families with accompanying children throughout Australia were assisted by homeless services. Sole fathers with children in their care who are homeless are a minority group within this overall population of homeless families and, as such, little is known about their experiences of homelessness and fathering. The present paper reports on an exploratory study of sole fathers with children in their care who were homeless in the Australian Capital Territory. The study identifies the fathers’ pathways into and experiences of homelessness, and the fathers share their stories of what it means to be a sole father. The paper identifies the issues fathers may experience when dealing with homelessness and fatherhood. An increased understanding of these experiences can contribute to the development of further research and improved practice with such families.
Creativity and Control: A Paradox. Evidence from the Levers of Control Framework

ABSTRACT: Both control and creativity are important drivers of organizational success (Gilson, Mathieu, Shalley, and Ruddy 2005; Hirst, van Knippenberg, Chen, and Sacramento 2011). However, they are often regarded as conflicting. We use the Levers of Control (LoC) framework to examine the relationships between a system of controls, empowerment, and creativity. Using survey data from 233 business unit managers, a structural equation model shows that the intensity of use of a LoC system of controls is positively associated with both empowerment and creativity. This suggests that the LoC system provides an environment that is rich with information and motivates employees to take action in purposeful, directed ways. This environment facilitates employees' perception that they have the ability to take actions, make decisions, and produce novel ideas. We conclude that there is not a conflict between control and creativity per se. Rather, paradoxically, creativity can flourish in the presence of control.
Improved immunofluorescence obtained with a tungsten halogen lamp in a modified inverted microscope.

The potential value of an iodine quartz lamp for use in a fluorescence microscope intended for immunofluorescence studies has been known for several years but development for this purpose has been restricted, mainly because suitable optical filters required for use with it have not been available. The fluorescence microscope described here incorporates an iodine quartz lamp with a larger filament than usual. Moreover, a high proportion of the available
Effects of Personality on Pair Programming

Personality tests in various guises are commonly used in recruitment and career counseling industries. Such tests have also been considered as instruments for predicting the job performance of software professionals both individually and in teams. However, research suggests that other human-related factors such as motivation, general mental ability, expertise, and task complexity also affect the performance in general. This paper reports on a study of the impact of the Big Five personality traits on the performance of pair programmers together with the impact of expertise and task complexity. The study involved 196 software professionals in three countries forming 98 pairs. The analysis consisted of a confirmatory part and an exploratory part. The results show that: (1) Our data do not confirm a meta-analysis-based model of the impact of certain personality traits on performance and (2) personality traits, in general, have modest predictive value on pair programming performance compared with expertise, task complexity, and country. We conclude that more effort should be spent on investigating other performance-related predictors such as expertise, and task complexity, as well as other promising predictors, such as programming skill and learning. We also conclude that effort should be spent on elaborating on the effects of personality on various measures of collaboration, which, in turn, may be used to predict and influence performance. Insights into such malleable, rather than static, factors may then be used to improve pair programming performance.
Happier with the Same: Job Satisfaction of Disadvantaged Workers

Job satisfaction evaluations depend not only on the objective circumstances that workers experience in their jobs, but also on their subjective dispositions, such as their aspirations, expectations, feelings of entitlement or personal evaluation criteria. We use matched employer–employee data from the United Kingdom to examine whether and how subjective dispositions influencing job satisfaction vary across workers with different socio-demographic traits. We approximate jobs using detailed occupations within workplaces and find that most of the variability in job satisfaction is at the worker rather than the proximate-job level, and that workers with disadvantaged statuses report higher satisfaction with the same jobs than those with advantaged statuses.
Setos' way to manage identities and well-being: shame and pride, opposition and openness

The paper examines how the tiny ethno-cultural group of Setos constructs its identity in the multicultural context. The study examines the validity of three acculturation models and tests earlier findings on the relationship between identity and well-being. The results suggest that Setos have clearly adopted a multicultural identity strategy while not merging different identities, and that they have managed to separate the material well-being from the pride of their identity. Despite its small size and peripheral location, the Setos' way to preserve their identity in a constantly changing context is an interesting lesson for other indigenous groups, and also for bigger neighbors.
Exposed Hydrophobic Residues in Human Immunodeficiency Virus Type 1 Vpr Helix-1 Are Important for Cell Cycle Arrest and Cell Death

The human immunodeficiency virus type 1 (HIV-1) accessory protein viral protein R (Vpr) is a major determinant for virus-induced G2/M cell cycle arrest and cytopathicity. Vpr is thought to perform these functions through the interaction with partner proteins. The NMR structure of Vpr revealed solvent exposed hydrophobic amino acids along helices 1 and 3 of Vpr, which could be putative protein binding domains. We previously showed that the hydrophobic patch along helix-3 was important for G2/M blockade and cytopathicity. Mutations of the exposed hydrophobic residues along helix-1 were found to reduce Vpr-induced cell cycle arrest and cell death as well. The levels of toxicity during virion delivery of Vpr correlated with G2/M arrest. Thus, the exposed hydrophobic amino acids in the amino-terminal helix-1 are important for the cell cycle arrest and cytopathicity functions of Vpr.
Syntectonic sedimentation effects on the growth of fold-and-thrust belts

We use two-dimensional mechanical models to investigate the effects of syntectonic sedimentation on fold-and-thrust belt development, testing variable syntectonic (wedge-top and foredeep) sediment thicknesses and flexural rigidities. Model results indicate a first-order control of syntectonic sedimentation on thrust-sheet length and thrust spacing. Thrust sheets are longer when syntectonic sediment thickness and/or flexural rigidity increase. Comparison with observations from several fold-and-thrust belts confirms this first-order control of syntectonic sedimentation.
REDD plus readiness implications for Sri Lanka in terms of reducing deforestation

Any system to compensate countries for reduced emissions from deforestation and forest degradation (REDD+) requires a historical reference level against which future performance can be measured. Here we examine the possibilities Sri Lanka, a small forest country with limited data on forest carbon stocks, has to get ready for REDD+. We construct a historical reference level using available forest inventory data combined with updated 2008 and 2009 in situ carbon density data for Sri Lankan forests. Furthermore, we use a combination of qualitative and quantitative data to attribute the clearing of Sri Lankan forests in the latest years for which national forest inventory data are available, 1992– 1996, to various proximate drivers and to estimate the opportunity cost of forest conservation. We estimate that baseline deforestation emissions in Sri Lanka amounted to 17 MtCO2 year –1 in the 1992– 1996 period, but conclude that it is challenging for Sri Lanka to produce a robust and accurate reference level due to the lack of nationally based inventories. We find that the majority of forest clearing (87%) is due to small-scale, rainfed farming, with the two other major drivers being rice and tea cultivation. Further, Sri Lankan revenues from REDD+ participation could be substantial, but they are sensitive to REDD+ policy transaction cost, highly uncertain timber revenues, and particularly the carbon price paid for emission reductions. The latter needs to be higher than $5-10/tCO2 if there are to be substantial incentives for Sri Lanka to participate in REDD+. There is, however, a large gap in the knowledge of deforestation drivers that needs to be filled if Sri Lanka is to formulate an effective policy response to forest degradation in REDD+. For successful REDD+ implementation in Sri Lanka to happen, technological assistance, readiness assistance, and continued political momentum are crucial.
Factors That Influence Adult Recidivism: An Exploratory Study in Pollsmoor Prison

Available statistics on recidivism in South Africa are severely limited, but estimates indicate that it is unacceptably high. This study uses data from the case files of two psychologists working in the Department of Correctional Services at Pollsmoor Prison, Cape Town, to describe the incidence, possible reasons for, and treatment of, recidivism. In addition, qualitative data in the form of transcripts of focus group interviews and semi-structured interviews are used to analyse the experiences and perceptions of inmates who have returned to prison on more than one occasion. The analysis suggests that prison behaviour is not an indicator of successful rehabilitation; rehabilitation interventions are often provided too late; learning to trust is important for rehabilitation, as is a shift from external to internal locus of control and learning to control emotions; drug abuse is a bad indicator for rehabilitation; and many rehabilitation programmes still focus on process rather than results. On the basis of these findings, it is recommended that half-way houses should be established; that there should be greater focus on inmate empowerment; that constancy of services and increased human resources should be provided; and that further research should be conducted into recidivism in South Africa.
Wearable AMC Backed Near-Endfire Antenna for On-Body Communications on Latex Substrate

A near-endfire, artificial magnetic conductor (AMC) backed wearable antenna is proposed in this paper for wireless body area networks operating in the 2.4-GHz industrial, scientific and medical (ISM) radio band. The latex substrate permittivity has accurately been characterized for realizing a flexible planar Yagi-Uda antenna printed on it using a large-area screenprinting process. The bidirectional-endfire radiation of Yagi- Uda antenna is changed to an off-axis near-endfire radiation using an AMC reflector also printed on latex. The antenna is separated from the upper AMC surface using flexible Styrofoam of thickness 0. 044λ0 at 2.4 GHz for the best compromise between keeping the antenna structure low profile and achieving an off-axis beam-tilt radiation of ~74° toward the endfire direction. The 0° reflection phase single-layered AMC and double-layered AMC (D-AMC) surfaces are proposed to reduce the body-absorbed radiation and, consequently, minimize the peak specific absorption rate (SAR) level for 2.4-GHz frequency band. Antenna performance in terms of return loss, radiation efficiency, extent of frequency detuning, gain, and SAR level is studied for free space as well as the CST MWS tissue-equivalent voxel model for all the proposed antenna designs. Antenna deformation bending study when placed on the human body is also performed in this paper. The antenna design is first optimized and fabricated on printed circuit board to verify the concept and then designed over the latex for actual human on-body all-flexible configuration. The Yagi-Uda antenna backed with D-AMC reflector demonstrates the measured return loss bandwidth of 45 MHz (2.425-2.47 GHz) and the gain of 0.12 dBi in the endfire direction with an improved on-body (chest) radiation efficiency of 78.97% and a reduced peak SAR level of 0.714 W/kg (average over 10-g tissue) for the compact overall flexible latex antenna volume of 0. 4λ0×0. 4λ0×0. 076λ0 at 2.4 GHz. To the best of our knowledge, this is the first latex-based endfire antenna for on-body 2.4-GHz wireless communications backed with an AMC periodic metamaterial surface.
Making the Indian: Colonial Knowledge, Alcohol, and Native Americans

L'A. montre comment les constructions de la pratique de consommation d'alcool par les Amerindiens ont pour objectif de renforcer et de reproduire les images coloniales de l'Indien, centrant son analyse sur le colonialisme en tant que conquete et controle des images des peuples sur eux-memes et sur les autres ; en tant que phenomene d'implantation d'idees etrangeres dans des espaces ou elles etaient inconnues auparavant. Il soutient que l'essentiel de ce que l'on sait sur la consommation d'alcool par les Amerindiens est une forme de connaissance coloniale qui cree des categories standardisees visant a renforcer les oppositions entre colonise et colonisateur. En attribuant des caracteristiques negatives a certains groupes la connaissance coloniale vise a maintenir le colonise dans une position de subordination. A partir notamment d'etudes menees dans le sud-ouest des Etats-Unis, l'A. identifie quatre domaines du pouvoir de la connaissance coloniale sur la representation de l'Indien et de l'alcool : les statistiques et l'epidemiologie ; le droit et la politique publique ; le marketing ; l'industrie du traitement de l'alcoolisme. Il se propose ainsi de mettre en garde contre une tendance des sciences sociales ou de la recherche biomedicale a reproduire et a renforcer les perceptions et les categories coloniales sur les Amerindiens.
Etnocentrizam, autoritarne tendencije i religioznost: relacije na uzorku zagrebačkih studenata

This paper presents the results of research through which an endeavour was made to establish the predictive importance of various authoritarian tendencies (traditional gender roles, authoritarian obedience, conformism) in relation to expressions of ethnocentrism, whose structure of attitudes indicates nationalistic sentiment. The second objective of the research was to determine the influence of declarative religiosity on the latent configuration of ethnocentrism and the variables of authoritarian tendencies. The research was conducted on a sample of first-year students at the University of Zagreb (N = 223). The homogeneity of the measuring instruments was checked by factor analysis with a varimax rotation, and their reliability was calculated by the Cronbach co-efficient. In further multivariate data processing, factor extracted dimensions were used. The results of regression analysis showed that traditional gender roles (patriarchalism) and conformism are significant predictors of ethnocentrism. The approximately 31% ethnocentrism variance was explained by predictor variables. The results of canonical discrimination analysis showed the considerable influence of declarative religiosity on the latent configuration of ethnocentrism and authoritarian tendencies. The structure of the canonical factor indicates the existence of a pattern of attitudes and values of a higher order, called “social conservatism”. A relatively small percentage of variance (around 12%) in the examined variables set can be attributed to differences in declarative religiosity, which points to the relatively modest significance of religiosity in the forecasting of social conservatism. Although the results of research comply with other researches conducted in Croatia on samples of the general population, the author shows, on the example of Voyvodina, that the interrelations of ethnocentrism, authoritarian tendencies, conformism and religiosity are not uniform in a society with people living in a different cultural heritage and political context.
Personality and learning processes underlying maverickism

Purpose – Maverickism is the tendency of an individual to be socially competent, creative, goal focussed, risk-taking and disruptive. Previous research with the five-factor model (FFM) shows that individuals high in maverickism exhibit both functional and dysfunctional tendencies. The purpose of this paper is to compare and contrast the descriptive FFM with the process-oriented hybrid model of learning in personality (HMLP), in the prediction of maverickism. Design/methodology/approach – Employing a cross-sectional design with 490 full-time workers the authors use the NEO-International Personality Item Pool and the Learning Styles Profiler to examine differences in the FFM and HMLP in the prediction of maverickism. Findings – Results with the FFM, identify extraversion, openness and (low) agreeableness as significant predictors of maverickism. All factors of the HMLP (except conscientious learning) significantly predict maverickism. Hierarchal regression analysis shows that the HMLP accounts for an additi.
Examining Uncertainty Avoidance, Relationship Quality, and Customer Loyalty in Two Cultures

ABSTRACT The study examines culture's role in the association of relationship quality with customer loyalty. Specifically, the association of relationship quality dimensions with loyalty was examined in a European high uncertainty avoidance culture (Turkey) and an Asian low uncertainty avoidance culture (Malaysia). Data were collected through a field survey of randomly selected bank customers in Ankara and Kuala Lumpur. Factor and Hierarchical Multiple Regression Analyses (HMRA) were employed for data analysis. The results show that relationship quality dimensions explain a significant amount of variance in customer loyalty. Trust and satisfaction are significantly associated with customer loyalty. Uncertainty avoidance is significantly associated with loyalty. The impact of trust on loyalty is moderated by uncertainty avoidance. As such, culture is an explanatory variable for customer loyalty.
Effects of Plectin Depletion on Keratin Network Dynamics and Organization

The keratin intermediate filament cytoskeleton protects epithelial cells against various types of stress and is involved in fundamental cellular processes such as signaling, differentiation and organelle trafficking. These functions rely on the cell type-specific arrangement and plasticity of the keratin system. It has been suggested that these properties are regulated by a complex cycle of assembly and disassembly. The exact mechanisms responsible for the underlying molecular processes, however, have not been clarified. Accumulating evidence implicates the cytolinker plectin in various aspects of the keratin cycle, i.e., by acting as a stabilizing anchor at hemidesmosomal adhesion sites and the nucleus, by affecting keratin bundling and branching and by linkage of keratins to actin filament and microtubule dynamics. In the present study we tested these hypotheses. To this end, plectin was downregulated by shRNA in vulvar carcinoma-derived A431 cells. As expected, integrin β4- and BPAG-1-positive hemidesmosomal structures were strongly reduced and cytosolic actin stress fibers were increased. In addition, integrins α3 and β1 were reduced. The experiments furthermore showed that loss of plectin led to a reduction in keratin filament branch length but did not alter overall mechanical properties as assessed by indentation analyses using atomic force microscopy and by displacement analyses of cytoplasmic superparamagnetic beads using magnetic tweezers. An increase in keratin movement was observed in plectin-depleted cells as was the case in control cells lacking hemidesmosome-like structures. Yet, keratin turnover was not significantly affected. We conclude that plectin alone is not needed for keratin assembly and disassembly and that other mechanisms exist to guarantee proper keratin cycling under steady state conditions in cultured single cells.
Ethical Dilemmas in Human Service Management: Identifying and Resolving the Challenges

Human service managers are called on to make a variety of difficult decisions that often involve fundamental conflicts in values. Such conflicts constitute ethical dilemmas. This qualitative exploratory study examines how human service managers (N = 40), from the United States, identify and resolve ethical dilemmas. The dilemmas identified by the managers tended to result in the restriction of missions, programs, services and practice methods. The resolution of these ethical problems often rested on following the very rules that created the dilemmas. Additional strategies included consultations and reliance on abstract principles, specifically those of one's spiritual faith. Missing, however, were systematic or evidence-based procedures for resolving challenges that often threatened the very goals of the human service agencies. The need for more careful training in the area of ethical problem solving that maintains the vision of human services is presented.
Comparison of efficacy and safety of ropivacaine with bupivacaine for intrathecal anesthesia for lower abdominal and lower limb surgeries

Background: A prospective randomized clinical study was conducted to study the efficacy and safety of ropivacaine with bupivacaine intrathecally for lower abdominal and lower limb surgeries. Material and Methods: 70 patients aged between 18 to 65 years were randomized into two groups, n = 35 in each group. Group A received 3 ml of (0.5%) isobaric bupivacaine (15 mg) and Group B 3 ml of (0.75%) isobaric ropivacaine (22.5 mg). Spinal anesthesia procedure was standardized. Haemodynamic parameters, onset and duration of sensory and motor blockade, level achieved, regression and side effects were compared between the two groups. Results: Onset and regression of sensory blockade in ropivacaine group was faster with a P < 0.001 which was statistically significant. Onset of motor blockade was rapid in both the groups but duration of motor blockade was significantly shorter in ropivacaine group. Excellent analgesia, with no side effects and stable haemodynamics was noted in ropivacaine group. Conclusion: Hence ropivacaine was safe and equally effective as bupivacaine for lower abdominal and lower limb surgeries with early motor recovery, providing early ambulation.
