Abusive Supervision and Workload Demands from Supervisors: Exploring Two Types of Supervisor‐related Stressors and their Association with Strain
Authors: Wu Tsung‐Yu , Hu Changya , Yang Chun‐Chi 
Published: August 2012

AbstractOur study aimed to identify two types of stressors from supervisors: abusive supervision (AS) and workload demands from supervisors (WDS). AS reflects the relationship dimension of supervisor‐related stressors, and WDS reflects the task dimension of supervisor‐related stressors. In Study 1, we attempted to distinguish between AS and WDS. The results of confirmatory factor analysis showed that AS and WDS are two distinct dimensions of supervisor‐related stressors. In Study 2, we utilized job demands–resources model and investigated whether AS and WDS can uniquely predict subordinates' emotional exhaustion (EE). We also explored whether perceived job characteristics (PJCs) have differential moderating effects on the relationships between the two dimensions of supervisor‐related stressors (AS and WDS) and EE. Consistent with our predictions, the results showed that both AS and WDS have incremental predictive effects on EE after controlling for the effect of the other. The results also revealed that PJCs weaken the WDS–EE relationship, not the AS–EE relationship. We discussed the theoretical and practical implications at the end.

Stress and Coping Mediate Relationships between Contingent and Global Self‐Esteem and Alcohol‐Related Problems among College Drinkers
Authors: Tomaka Joe , Morales‐Monks Stormy , Shamaley Angelee Gigi 
Published: August 2012

AbstractThis study examined the hypotheses that contingent self‐esteem would be positively associated with alcohol‐related problems and that global self‐esteem would be negatively associated with such problems. It also examined the hypothesis that high stress and maladaptive coping would mediate these relationships. A sample of college students (n = 399) who were predominantly Hispanic (89%) completed measures of global and contingent self‐esteem; stress and coping; and alcohol‐related problems. Correlational and latent variable analyses indicated that contingent self‐esteem positively related to alcohol‐related problems, with maladaptive coping mediating this relationship. In contrast, global self‐esteem negatively related to such problems, a relationship that was also mediated by maladaptive coping and stress. Overall, the results highlight the potentially harmful consequences of contingent self‐worth and the adaptive nature of non‐contingent self‐esteem. They also demonstrate the important role that coping plays in mediating self‐esteem's associations with alcohol‐related problems. Copyright © 2012 John Wiley & Sons, Ltd.
Distance‐Mediated Plasmonic Dimers for Reusable Colorimetric Switches: A Measurable Peak Shift of More than 60 nm
Authors: Guo Longhua , Ferhan Abdul Rahim , Chen Hailan , Li Changming , Chen Guonan , Hong Seungpyo , Kim Dong‐Hwan 
Published: August 2012

AbstractThe first reconfigurable colorimetric DNA switches based on target DNA binding are reported. This DNA binding actuates a change in the interparticle distance between gold nanoparticle dimers. A significant spectral shift of 68 nm is achievable from on‐off switching. The reconfigurability is possible owing to thiol and EDC‐imidazole coupling which anchors the DNA linkers to the nanoparticles. The huge spectral shift allows the unaided eye to observe single target biomolecular binding event in real time under a darkfield microscope. The limit‐of‐detection for target molecules in PBS and human serum are 10−13 M and 10−11 M respectively. An improved fabrication strategy via asymmetric functionalization is also described, assisted by solid phase synthesis which minimizes the formation of trimers and multimers.
Why People Don't Ask: Understanding Initiation Behavior in International Negotiations
Authors: Volkema Roger J. 
Published: August 2012

AbstractNegotiation is an interactive process that is important to all aspects of organizational success, a process that begins with communicating one's wants or needs. For many individuals, engaging others and asking for what one wants (i.e., initiating a negotiation) is a challenging task, made more difficult in an international context. Yet due to the integration of world markets, this is exactly the type of environment that many organizational representatives are facing with increasing regularity. This article offers an overview of the personal characteristics and situational factors that influence an individual initiating a negotiation (engaging a counterpart, making a request, and optimizing that request), with specific attention to seven cultural factors that must be understood to be most effective in international settings. The ways in which these cultural factors are likely to affect one's decision to engage a counterpart and style of delivery are illustrated for three countries: the United States, China, and Brazil. © 2012 Wiley Periodicals, Inc.
Shared Vision in MNE Subsidiaries: The Role of Formal, Personal, and Social Control in Its Development and Its Impact on Subsidiary Learning
Authors: Colakoglu Saba 
Published: August 2012

AbstractGiven the strategic importance of achieving global integration and worldwide learning for most multinational enterprises (MNEs), this article focuses on “shared vision” as a critical mechanism for realizing both goals. Specifically, this paper investigates the impact of three types of control mechanisms—formal (headquarters imposed rules and decisions), personal (the presence of expatriates), and social (social interaction among subunits) control—on building shared vision in subsidiaries and examines the subsequent impact of having shared vision on subsidiary learning. Overall, data from 99 subsidiaries located in the United States and headquartered either in Europe or Japan show that personal and social mechanisms of control are effective in building shared vision whereas formal control mechanisms have no impact. Results also support a significant relationship between shared vision and subsidiary learning. © 2012 Wiley Periodicals, Inc.
How Industry Dynamics Influence the Internationalization–Performance Relationship: Evidence From Technology‐Intensive Firms
Authors: Elango B. 
Published: August 2012

AbstractThe relationship between internationalization and performance has been the topic of a significant number of research studies, which report a mixed pattern of findings. However, the incorporation of global industry characteristics in the testing of this relationship has not been a facet of these studies. This article investigates the impact of intrafirm trade and differential market growth of the industry on the relationship between internationalization and performance. It focuses on technology‐intensive industries using a sample of 795 firms drawn from five countries. Findings indicate that internationalization has a positive relationship (which is quadratic in nature) with performance. Intrafirm trade and differential growth rates were found to interact with the relationship between internationalization and performance, thereby indicating the benefits of internationalization to be contingent on global industry characteristics. © 2012 Wiley Periodicals, Inc.

Brazil Post‐Lula: Challenges and Opportunities Facing the Brazilian Business Environment
Authors: Gouvea Raul 
Published: August 2012

AbstractThe Brazilian economy indicates great potential for future economic growth. An increasing and affluent middle class, expanding exports, and foreign reserves are testimonies of Brazil's recent accomplishments. The country, however, still faces a number of challenges that may compromise its sustainable long‐term economic goals and objectives. This article focuses on the Luiz Inacio “Lula” da Silva government's economic performance. The article's main findings show increasing bottlenecks being created as a result of the Lula government's eight years of low economic growth rates, which have penalized the country's competitiveness. The newly elected president, Dilma Rousseff, will inherit a substantial investment deficit in the areas of infrastructure, education, health care, research and development (R&D), and innovation, as well as Brazil's worst public debt/gross domestic product (GDP) ratio in the past 100 years. These conditions will prevent Brazil from growing and developing at faster rates. This article also elaborates on Dilma Rousseff's most recent statements and discusses likely future paths for the Brazilian economy. © 2012 Wiley Periodicals, Inc.

AbstractThree new coordination compounds, [Pb(HBDC‐I4)2(DMF)4](1) and [M(BDC‐I4)(MeOH)2(DMF)2]n (M = ZnII for 2 and MnII for (3) (H2BDC‐I4 = 2, 3, 5, 6‐tetraiodo‐1, 4‐benzenedicarboxylic acid), were synthesized and characterized by elemental analysis, IR spectroscopy, thermogravimetric (TG) analysis, and X‐ray single crystal structure analysis. Single‐crystal X‐ray diffraction reveals that 1 crystallizes in the monoclinic space group C2/c and has a discrete mononuclear structure, which is further assembled to form a two‐dimensional (2D) layer through intermolecular O–H···O and C–H···O hydrogen bonding interactions. The isostructural compounds 2 and 3 crystallize in the space group P21/c and have similar one‐dimensional (1D) chain structures that are extended into three‐dimensional (3D) supramolecular networks by interchain C–H···π interactions. The PbII and ZnII complexes 1 and 2 display similar emissions at 472 nm in the solid state, which essentially are intraligand transitions.

Published: August 2012

AbstractReactions of H3tda (H3tda = 1H‐1, 2, 3‐triazole‐4, 5‐dicarboxylic acid) with Sm(NO3)3·6H2O, Eu(NO3)3·6H2O, and Tb(NO3)3·6H2O, in the presence of NaOH under hydrothermal conditions, produced three new coordination polymers, [Ln2(tda)2(H2O)3]·5H2O [Ln = Sm (1), Eu (2), Tb (3)]. These compounds were structurally characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis (TGA), PXRD and single‐crystal X‐ray diffraction. The single‐crystal X‐ray diffraction studies of compounds 1–3 reveal that all compounds are three‐dimensional porous structures with chiral frameworks. Furthermore, the luminescence studies of compound 2 and 3 in the solid state reveal that they are potential luminescent materials at room temperature.
Synthesis and Crystal Structure of the Cesium Silver ­Permanganate Cs3Ag[MnO4]4

Published: August 2012

AbstractAfter successful syntheses and structural refinements of the already known permanganates of cesium (Cs[MnO4]) and silver (Ag[MnO4]) we started to blend aqueous solutions of both components in various molar ratios. From crystallization experiments of these mixtures only three species of crystals with different chemical compositions were obtained: tricesium monosilver tetrakispermanganate (Cs3Ag[MnO4]4) and, depending upon the respective ratio, either additional silver permanganate or surplus cesium permanganate, namely. The new title compound crystallizes in the orthorhombic space group Pnnm (no. 58) with two formula units per unit cell and cell dimensions of a = 764.53(4), b = 1883.57(9) and c = 584.34(3) pm. The crystal structure of Cs3Ag[MnO4]4 consists of two crystallographically distinguishable cesium cations. (Cs1)+ is surrounded by fourteen oxygen atoms constructing a slightly distorted bicapped hexagonal prism. These polyhedra are connected through edge‐sharing with two other polyhedra of this kind to form chains along [001]. The chains are linked to each other via sixfold coordinated Ag+ cations (d(Ag–O) = 238–246 pm), arranged in such a manner that they link three oxygen atoms of two cesium polyhedra, leading to a two‐dimensional layer spreading out parallel to the (001) plane. Together with the two crystallographically different tetrahedral oxomanganate(VII) anions [MnO4]– (d(Mn–O) = 161–162 pm) the other kind of cesium cations ((Cs2)+ with CN = 13) finally connect these layers three‐dimensionally.
Does the Quality, Accuracy, and Readability of Information about Lateral Epicondylitis on the Internet Vary with the Search Term Used?

Published: August 2012

Background Concern exists over the quality, accuracy, and accessibility of online information about health care conditions. The goal of this study is to evaluate the quality, accuracy, and readability of information available on the internet about lateral epicondylitis. Methods We used three different search terms (“tennis elbow,”“lateral epicondylitis,” and “elbow pain”) in three search engines (Google, Bing, and Yahoo) to generate a list of 75 unique websites. Three orthopedic surgeons reviewed the content of each website and assessed the quality and accuracy of information. We assessed each website's readability using the Flesch-Kincaid method. Statistical comparisons were made using ANOVA with post hoc pairwise comparisons. Results The mean reading grade level was 11.1. None of the sites were under the recommended sixth grade reading level for the general public. Higher quality information was found when using the terms “tennis elbow” and “lateral epicondylitis” compared to “elbow pain” ( p<0.001). Specialty society websites had higher quality than all other websites ( p<0.001). The information was more accurate if the website was authored by a health care provider when compared to non-health care providers ( p=0.003). Websites seeking commercial gain and those found after the first five search results had lower quality information. Conclusions Reliable information about lateral epicondylitis is available online, especially from specialty societies. However, the quality and accuracy of information vary significantly with the search term, website author, and order of search results. This leaves less educated patients at a disadvantage, particularly because the information we encountered is above the reading level recommended for the general public.
Cryoconservation de spermatozoïdes avant vasectomie: utilité et paradoxes à travers l’activité des CECOS
Authors: Gillois P. , Rigot J. -M. , Juillard J. -C. ,   Fédération française des CECOS, Hennebicq S. 
Published: August 2012

Résumé
Le recours à la vasectomie demeure largement moins utilisé en France que dans d’autres pays comme le montrent les données présentées dans cet article. Par ailleurs, environ 12 % des hommes qui ont recours à ce moyen de stérilisation volontaire vont dans le même temps procéder à une congélation de spermatozoïdes. Proposer de préserver la fertilité d’hommes qui n’envisagent pas ou plus de projet de paternité peut apparaître paradoxal. Nous reprenons dans cet article les éléments de réglementation, réflexion et évolution au cours du temps de la pratique de la vasectomie combinée à la congélation de spermatozoïdes. Les données montrent qu’environ 5 % des hommes qui ont préservé leur fertilité avant la chirurgie demanderont ultérieurement une utilisation de ces spermatozoïdes, le plus souvent lors d’une nouvelle union. L’analyse de l’évolution des pratiques montre également qu’actuellement, le recours aux inséminations artificielles a été largement supplanté par l’utilisation des techniques de fécondation in vitro avec des chances de grossesse nettement supérieures. Enfin, au regard de l’évolution de la réglementation et de l’évolution des pratiques, nous posons la question de l’utilité de continuer à proposer une préservation de fertilité préalablement à la vasectomie et présentons des pistes de réflexion sur ce point.
Parent attachment, school commitment, and problem behavior trajectories of diverse adolescents
Authors: Cavendish Wendy , Nielsen Amie L. , Montague Marjorie 
Published: August 2012

ABSTRACTThe purpose of this study was to examine the growth trajectories from early to late adolescence of teacher ratings of students' behavior problems from 9th through 11th grade and student self‐reports of alcohol use in a sample of predominately minority adolescents (n = 179, 90% African‐American and/or Hispanic, 43% boys, 57% girls) in a large, urban school district. The study investigated whether parent attachment, school commitment, gender, race/ethnicity, and educational placement influenced these outcomes. Multi‐level growth modeling was the primary statistical procedure used. Results indicated that increased parent attachment was associated with reduced levels of alcohol use and school commitment was not associated with growth trajectories of problem behavior in the multilevel models, although gender, race/ethnicity and special education placement were significant predictors. Our findings suggest that teachers perceive greater levels of behavior problems for minority students and youth in special education. Student self reports also indicate adolescent frequency of alcohol use increases over time.

AbstractObjectiveTo determine the value of negative cone margins in predicting residual disease in women with adenocarcinoma in situ (ACIS).MethodsData were retrospectively analyzed from 60 women with ACIS who underwent conization at Chiang Mai University Hospital between March, 1998, and December, 2010. Negative margin status was defined as absence of neoplastic epithelium at all margins, coupled with presence of normal cervical epithelium. The association between the incidence of residual lesions and cone margin status was analyzed via χ2 or Fisher exact test.ResultsWhen adjusted for age and completeness of visualization of the cervical squamocolumnar junction during colposcopy, women who underwent loop electrosurgical excision procedure were 4 times more likely to have positive cone margins than those who underwent cold‐knife conization (95% CI, 1.13–16.43). Residual disease was not found among 26 women who had negative cone margins, but was observed in 17 (65.4%) of 26 women with positive cone margins (P < 0.001).ConclusionWomen with ACIS who had negative cone margins were found to have a notably low risk of residual disease. Adherence to the standard method of cone sampling and criteria for negative margin status might contribute to a high predictive value of negative cone margins.
Shear instability of internal solitary waves in Euler fluids with thin pycnoclines
Authors: Almgren A. , Camassa R. , Tiron R. 
Published: August 2012

AbstractThe stability with respect to initial condition perturbations of solitary travelling-wave solutions of the Euler equations for continuously, stably stratified, near two-layer fluids is examined numerically and analytically for a set of parameters of relevance for laboratory experiments. Numerical travelling-wave solutions of the Dubreil–Jacotin–Long equation are first obtained with a variant of Turkington, Eyland and Wang’s iterative code by testing convergence on the equation’s residual. In this way, stationary solutions with very thin pycnoclines (and small Richardson numbers) approaching the near two-layer configurations used in experiments can be obtained, allowing for a stability study free of non-stationary effects, introduced by lack of numerical resolution, which develop when these solutions are used as initial conditions in a time-dependent evolution code. The thin pycnoclines in this study permit analytical results to be derived from strongly nonlinear models and their predictions compared with carefully controlled numerical simulations. This brings forth shortcomings of simple criteria for shear instability manifestations based on parallel shear approximations due to subtle higher-order effects. In particular, evidence is provided that the fore–aft asymmetric growth observed in all simulations requires non-parallel shear analysis. Collectively, the results of this study reveal that while the wave-induced shear can locally reach unstable configurations and give rise to local convective instability, the global wave/self-generated shear system is in fact stable, even for extreme cases of thin pycnoclines and near-maximum-amplitude waves.
Direct numerical simulation of axisymmetric wakes embedded in turbulence
Authors: Rind Elad , Castro Ian P. 
Published: August 2012

AbstractDirect numerical simulation has been used to study the effects of external turbulence on axisymmetric wakes. In the absence of such turbulence, the time-developing axially homogeneous wake is found to have the self-similar properties expected whereas, in the absence of the wake, the turbulence fields had properties similar to Saffman-type turbulence. Merging of the two flows was undertaken for three different levels of external turbulence (relative to the wake strength) and it is shown that the presence of the external turbulence enhances the decay rate of the wake, with the new decay rates increasing with the relative strength of the initial external turbulence. The external turbulence is found to destroy any possibility of self-similarity within the developing wake, causing a significant transformation in the latter as it gradually evolves towards the former.
