THE ANTECEDENTS OF JOB CRAFTING: PERCEIVED ORGANIZATIONAL SUPPORT, JOB CHARACTERISTICS AND SELF-EFFICACY

his study aims to investigate some antecedents of job crafting. Within the literature, studies suggest that some individual and organizational factors lead employees to customize their jobs according to their abilities, preferences and needs. Therefore, self-efficacy, perceived organizational support and job characteristics are considered as predictors of job crafting within the scope of the study. For the purpose of the research, the data which are collected from 252 hotel employees by the survey method are analyzed by using the structural equation modelling. According to the results of study, from the individual antecedents’ perspective, it is found out that selfefficacy has a positive and significant effect on job crafting. However, from the organizational perspective, research results indicate that some of the dimensions of job characteristics skill variety and feedback effect job crafting positively, whereas task significance & autonomy dimension has no significant effects on job crafting. Moreover, it is seen that perceived organizational support dimensions have no significant effect on job crafting.
[Validity and reliability of the quality of life questionnaire (EORTC QLQ C30) and its breast cancer module (EORTC QLQ BR23)].

OBJECTIVES The aim of this study was to assess validity and reliability of the EORTC QLQ C30 and BR23 questionnaires among patients with breast neoplasm in Poland. MATERIAL AND METHODS Analysis was done on the basis of research conducted at the First Department of General Surgery JUMC, Kraków, among 105 women. Two aspects of questionnaire validity have been analyzed: construct validity using principal component analysis and criterion validity evaluated by comparison of two clinical subgroups of patients. Reliability analysis was done by estimating internal consistency using Cronbach's alpha coefficient and correlations between items and hypothesized scales. In addition, test-retest reliability was evaluated by calculating the correlation coefficient between two assessments, done 6 and 12 months after treatment. RESULTS All scales met Nunnally's criterion except for the scale of nausea and vomiting. Almost all variables met Kline's criterion, except for two variables: one from the scale of physical functioning and the other a part of the scale of systemic therapy side effects. High correlations obtained by the test-retest method confirmed the reliability of all scales. Analysis showed some fault in the theoretical validity of the scale of systemic therapy side effects. Nonetheless, criterion validity was confirmed for all scales. CONCLUSIONS Results have confirmed the validity and reliability of the EORTC QLQ C30 and BR23 tests as instruments for quality of life evaluation in Polish patients.

Aim: The aim of this study was to investigate heart rate variability (HRV) in a clinical sample of female adolescents with anxiety disorders (AD) and/or major depressive disorder (MDD) compared with healthy controls and to assess the effect of selective serotonin reuptake inhibitors (SSRI) on HRV.
Mouse behavioral mutants have neuroimaging abnormalities

Impaired cognitive, memory, or motor performance is a distinguishing characteristic of neurological diseases. Although these symptoms are frequently the most evident in human patients, additional markers of disease are critical for proper diagnosis and staging. Noninvasive neuroimaging methods have become essential in this capacity and provide means of evaluating disease and tracking progression. These imaging methods are also becoming available to scientists in the research laboratory for assessment of animal models of neurological disease. Imaging in mouse models of neurological disease is of particular interest, owing to the availability of inbred strains and genetic manipulation tools that permit detailed investigation of the roles of various genes and gene products in disease pathogenesis. However, the relative prevalence of neuroimaging abnormalities in mice exhibiting neurological symptoms has not been reported. This prevalence has both theoretical and practical value because it is influenced by both the sensitivity of macroscopic anatomical measures to underlying genetic and disease processes and by the efficiency of neuroimaging in detecting and characterizing these effects. In this paper, we describe a meta‐analysis of studies involving behavioral mouse mutants at our laboratory. In summary, we have evaluated 15 different mutant genotypes, of which 13 showed abnormal neuroimaging findings. This indicates a surprisingly high prevalence of neuroimaging abnormalities (87%) and suggests that disease processes affecting behavior generally alter neuroanatomy as well. As a consequence, neuroimaging provides a highly sensitive marker of neurological disease in mice exhibiting abnormal behavior. Hum Brain Mapp 2007. © 2007 Wiley‐Liss, Inc.
An OpenCL framework for heterogeneous multicores with local memory

In this paper, we present the design and implementation of an Open Computing Language (OpenCL) framework that targets heterogeneous accelerator multicore architectures with local memory. The architecture consists of a general-purpose processor core and multiple accelerator cores that typically do not have any cache. Each accelerator core, instead, has a small internal local memory. Our OpenCL runtime is based on software-managed caches and coherence protocols that guarantee OpenCL memory consistency to overcome the limited size of the local memory. To boost performance, the runtime relies on three source-code transformation techniques, work-item coalescing, web-based variable expansion and preload-poststore buffering, performed by our OpenCL C source-to-source translator. Work-item coalescing is a procedure to serialize multiple SPMD-like tasks that execute concurrently in the presence of barriers and to sequentially run them on a single accelerator core. It requires the web-based variable expansion technique to allocate local memory for private variables. Preload-poststore buffering is a buffering technique that eliminates the overhead of software cache accesses. Together with work-item coalescing, it has a synergistic effect on boosting performance. We show the effectiveness of our OpenCL framework, evaluating its performance with a system that consists of two Cell BE processors. The experimental result shows that our approach is promising.
Didactic and methodological conceptions on surfing teaching

Introduction Surf is a sport that in the last few years has had a considerable increasing number of athletes and that’s why it’s important to develop studies in order to describe and explain how the learning process of the athlete occurs, in what conditions he learns and how coaches develop the Surf’s teaching and training process. The aim of this study is to determine specific features about the knowledge concerning coach’s conceptions and methodologies as well as the way they proceed when organizing curricular contents.
Vertical pitch limitations on performance enhancement in bonded three-dimensional interconnect architectures

A three-dimensional wire-length distribution is derived and applied to determine an optimal n-tier multilevel interconnect architecture for a 0.1 μm ASIC. Ideally, utilization of a threedimensional architecture consisting of four strata for an interconnect limited layout area leads to a 14 times increase in clock frequency, a 92% reduction in total area, or a 50% reduction in the required number of metal levels. However, vertical pitch limitations resulting from alignment tolerances in bonding of wafers can restrict the vertical wiring density to the extent of compromising the potential advantages of three-dimensional homogeneous systems.
Determining Vaccination Frequency in Farmed Rainbow Trout Using Vibrio anguillarum O1 Specific Serum Antibody Measurements

Background Despite vaccination with a commercial vaccine with a documented protective effect against Vibrio anguillarum O1 disease outbreaks caused by this bacterium have been registered among rainbow trout at Danish fish farms. The present study examined specific serum antibody levels as a valid marker for assessing vaccination status in a fish population. For this purpose a highly sensitive enzyme-linked immunosorbent assay (ELISA) was developed and used to evaluate sera from farmed rainbow trout vaccinated against V. anguillarum O1. Study Design Immune sera from rainbow trout immunised with an experimental vaccine based on inactivated V. anguillarum O1 bacterin in Freund’s incomplete adjuvant were used for ELISA optimisation. Subsequently, sera from farmed rainbow trout vaccinated with a commercial vaccine against V. anguillarum were analysed with the ELISA. The measured serum antibody levels were compared with the vaccine status of the fish (vaccinated/unvaccinated) as evaluated through visual examination. Results Repeated immunisation with the experimental vaccine lead to increasing levels of specific serum antibodies in the vaccinated rainbow trout. The farmed rainbow trout responded with high antibody levels to a single injection with the commercial vaccine. However, the diversity in responses was more pronounced in the farmed fish. Primary visual examinations for vaccine status in rainbow trout from the commercial farm revealed a large pool of unvaccinated specimens (vaccination failure rate = 20%) among the otherwise vaccinated fish. Through serum analyses using the ELISA in a blinded set-up it was possible to separate samples collected from the farmed rainbow trout into vaccinated and unvaccinated fish. Conclusions Much attention has been devoted to development of new and more effective vaccines. Here we present a case from a Danish rainbow trout farm indicating that attention should also be directed to the vaccination procedure in order to secure high vaccination frequencies necessary for optimal protection with a reported effective vaccine.
Finding low-entropy sets and trees from binary data

The discovery of subsets with special properties from binary data hasbeen one of the key themes in pattern discovery. Pattern classes suchas frequent itemsets stress the co-occurrence of the value 1 in the data. While this choice makes sense in the context of sparse binary data, it disregards potentially interesting subsets of attributes that have some other type of dependency structure. We consider the problem of finding all subsets of attributes that have low complexity. The complexity is measured by either the entropy of the projection of the data on the subset, or the entropy of the data for the subset when modeled using a Bayesian tree, with downward or upward pointing edges. We show that the entropy measure on sets has a monotonicity property, and thus a levelwise approach can find all low-entropy itemsets. We also show that the tree-based measures are bounded above by the entropy of the corresponding itemset, allowing similar algorithms to be used for finding low-entropy trees. We describe algorithms for finding all subsets satisfying an entropy condition. We give an extensive empirical evaluation of the performance of the methods both on synthetic and on real data. We also discuss the search for high-entropy subsets and the computation of the Vapnik-Chervonenkis dimension of the data.
Grasp sensing for human-computer interaction

The way we grasp an object depends on several factors, e.g. the intended goal or the hand's anatomy. Therefore, a grasp can convey meaningful information about its context. Inferring these factors from a grasp allows us to enhance interaction with grasp-sensitive objects. This paper highlights an grasp as an important source of meaningful context for human-computer interaction and gives an overview of prior work from other disciplines. This paper offers a basis and framework for further research and discussion by proposing a descriptive model of meaning in grasps. The GRASP model combines five factors that determine how an object is grasped: goal, relationship between user and object, anatomy, setting, and properties of the object. The model is validated both from an epistemological perspective and by applying it to scenarios from related work.
Congruency of Sex-Role Identification in Normal and Disturbed Adolescent Males

17 pre-delinquent, 17 mixed psychiatric, and 17 normal adolescent males and their parents were compared for sex-role orientation and preference. No differences were found among groups. Sex-role orientation and preference were appropriate for each group, indicating a congruence between biological sex and sex-role identification and interests. A disturbance in sex-role orientation was not associated with the adolescent psychopathology surveyed here. Results suggest that troubled adolescents may not show the close association between sex-role disturbance and psychopathology found in adult disorders.
Heterogeneous Multi-core Parallel SGEMM Performance Testing and Analysis on Cell/B.E Processor

Matrix multiplication is one of the most common numerical operations in the field of scientific computing, which is the kernel routine of Level 3 BLAS. The STI CELL processor is a heterogeneous multiprocessor with a unique design to achieve high peak floating point performance. As matrix multiplication operation is essential for a wide range of numerical algorithms, so performance improvements to the GEMM routine immediately can benefit the entire algorithm. In this paper, we provide a new way to utilize the hardware features of Cell to achieve better performance on the Single Precision General Matrix Multiplication (SGEMM), through both heterogeneous PPEs and SPEs parallelization, our method gains speedup over the Cell SDK (2.5%). An extra speedup about 30% of performance is achieved via interleaved memory allocation, which improves memory access.
A straightforward ΣΔ fractional-N phase-locked loop HDL design for RF applications

The present paper describes a systematic straightforward design of a Σ-Δ fractional-N Phase-Locked Loop based on HDL behavioral modeling. The proposed design consists in describing the mixed mode behavior of this Σ-Δ fractional-N PLL architecture starting from the specifications of each building block. The HDL models of critical PLL blocks have been described in VHDL-AMS to predict the different over-all specifications. The effect of different noise sources has been accurately introduced to study the PLL system performances. The obtained results are compared with transistor-level simulations to validate the effectiveness of the proposed models.
Does the Job Satisfaction—Job Performance Relationship Vary Across Cultures?

The purpose of this study is to examine whether culture moderates the relationship between job satisfaction and job performance. Multiple theoretical frameworks regarding culture are used as the theoretical guide. Based on meta-analytical moderator tests, the authors find some support for their hypotheses that the effect size for the job satisfaction—job performance relationship is likely to be stronger in individualistic (vs. collectivistic) cultures, in low-power-distance (vs. high-power-distance) cultures, in low-uncertainty-avoidance (vs. high-uncertainty-avoidance) cultures, and in masculine (vs. feminine) cultures. They also observe stronger evidence of these effects for task performance than for contextual performance. Implications for theory, practice, and future research are discussed.
Performance analysis of a linear MMSE receiver for bandlimited random-CDMA using quadriphase spreading over multipath channels

This paper analyzes the bit-error-rate (P/sub e/) performance of a linear minimum mean-square error (LMMSE) receiver for bandlimited direct-sequence code-division multiple-access systems which use quadriphase spreading with aperiodic pseudonoise (PN) sequences. The analysis is based on the improved Gaussian approximation (IGA) with focus on chip pulse shaping. It shows that the IGA reduces to the standard Gaussian approximation (SGA) if 1) random quadriphase spreading is employed, 2) the spreading factor takes moderate to large values, and 3) the chip pulse excess bandwidth (BW) is zero. Hence, the SGA, known for its inaccuracy in low regions of P/sub e/, remains an accurate approximation even when the number of active users in the system is small as long as the aforementioned conditions are met. The analysis holds for either matched or different transmit and receive filters. Consequently, closed form conditional P/sub e/ expressions are derived for the coherent selective RAKE and the LMMSE receivers and verified with Monte Carlo simulations. Numerical results are presented to illustrate the performance improvement achieved by the LMMSE receiver which, in contrast to the coherent selective RAKE receiver, not only suppresses interference when the excess BW of chip pulse is nonzero, but also harnesses the energy of all paths of the desired user. Under the examined scenarios tailored toward current narrowband system settings, the LMMSE receiver achieves 60% gain in capacity over the selective RAKE receiver. A third of the gain is due to interference suppression capability of the receiver while the rest is credited to its ability to collect the energy of the desired user diversified to many paths. Future wideband systems will yield an ever larger gain.
Southern Ocean control of silicon stable isotope distribution in the deep Atlantic Ocean

The fractionation of silicon (Si) stable isotopes by biological activity in the surface ocean makes the stable isotope composition of silicon (δ30Si) dissolved in seawater a sensitive tracer of the oceanic biogeochemical Si cycle. We present a high‐precision dataset that characterizes the δ30Si distribution in the deep Atlantic Ocean from Denmark Strait to Drake Passage, documenting strong meridional and smaller, but resolvable, vertical δ30Si gradients. We show that these gradients are related to the two sources of deep and bottom waters in the Atlantic Ocean: waters of North Atlantic and Nordic origin carry a high δ30Si signature of ≥+1.7‰ into the deep Atlantic, while Antarctic Bottom Water transports Si with a low δ30Si value of around +1.2‰. The deep Atlantic δ30Si distribution is thus governed by the quasi‐conservative mixing of Si from these two isotopically distinct sources. This disparity in Si isotope composition between the North Atlantic and Southern Ocean is in marked contrast to the homogeneity of the stable nitrogen isotope composition of deep ocean nitrate (δ15N‐NO3). We infer that the meridional δ30Si gradient derives from the transport of the high δ30Si signature of Southern Ocean intermediate/mode waters into the North Atlantic by the upper return path of the meridional overturning circulation (MOC). The basin‐scale deep Atlantic δ30Si gradient thus owes its existence to the interaction of the physical circulation with biological nutrient uptake at high southern latitudes, which fractionates Si isotopes between the abyssal and intermediate/mode waters formed in the Southern Ocean.
Layer II/III of the Prefrontal Cortex: Inhibition by the Serotonin 5-HT1A Receptor in Development and Stress

The modulation of the prefrontal cortex by the neurotransmitter serotonin (5-HT) is thought to play a key role in determining adult anxiety levels. Layer II/III of the prefrontal cortex, which mediates communication across cortical regions, displays a high level of 5-HT1A receptor binding in normal individuals and a significantly lower level in patients with mood and anxiety disorders. Here, we examine how serotonin modulates pyramidal neurons in layer II/III of the rat prefrontal cortex throughout postnatal development and in adulthood. Using whole cell recordings in brain slices of the rat medial prefrontal cortex, we observed that serotonin directly inhibits layer II/III pyramidal neurons through 5-HT1A receptors across postnatal development (postnatal days 6–96). In adulthood, a sex difference in these currents emerges, consistent with human imaging studies of 5-HT1A receptor binding. We examined the effects of early life stress on the 5-HT1A receptor currents in layer II/III. Surprisingly, animals subjected to early life stress displayed significantly larger 5-HT1A-mediated outward currents throughout the third and fourth postnatal weeks after elevated 5-HT1A expression during the second postnatal week. Subsequent exposure to social isolation in adulthood resulted in the almost-complete elimination of 5-HT1A currents in layer II/III neurons suggesting an interaction between early life events and adult experiences. These data represent the first examination of functional 5-HT1A receptors in layer II/III of the prefrontal cortex during normal development as well as after stress.
Distinct kinetics and dynamics of cross‐presentation in liver sinusoidal endothelial cells compared to dendritic cells

Cross‐presentation is an important function of immune competent cells, such as dendritic cells (DCs), macrophages, and an organ‐resident liver cell population, i.e., liver sinusoidal endothelial cells (LSECs). Here, we characterize in direct comparison to DCs the distinct dynamics and kinetics of cross‐presentation employed by LSECs, which promote tolerance induction in CD8 T cells. We found that LSECs were as competent in cross‐presenting circulating soluble antigen ex vivo as DCs at a per‐cell basis. However, antigen uptake in vivo was 100‐fold more pronounced in LSECs, indicating distinct mechanisms of cross‐presentation. In contrast to mannose‐receptor–mediated antigen uptake and routing into stable endosomes dedicated to cross‐presentation in DCs, we observed distinct antigen‐uptake and endosomal routing with high antigen turnover in LSECs that resulted in short‐lived cross‐presentation. Receptor‐mediated endocytosis did not always lead to cross‐presentation, because immune‐complexed antigen taken up by the Fc‐receptor was not cross‐presented by LSECs, indicating that induction of CD8 T cell tolerance by LSECs is impaired in the presence of preexisting immunity. Conclusion: These results provide a mechanistic explanation how organ‐resident LSECs accommodate continuous scavenger function with the capacity to cross‐present circulating antigens using distinct kinetics and dynamics of antigen‐uptake, routing and cross‐presentation compared to DCs.

Mindfulness in Participatory Medicine: Context & Relevance

Summary: Background: Therapeutic modalities involving the practice of mindfulness are gaining wide acceptance as effective interventions in medicine and psychotherapy. A growing library of well-designed research studies demonstrate significant and enduring improvements in a host of physical and mental health domains as a consequence of the practice. This effectiveness may be due in large part to the nature of mindfulness, which is an elemental dimension of proactive self-care. Intention: In this review and position paper we outline and explore three decades of evidence for the relevance of mindfulness in the model of Participatory Medicine. Also included is a summary of one community’s experience with a mindfulness-based intervention, MindfulnessBased Stress Reduction (MBSR). The authors of this paper are community physicians, psychologists, therapists, patients, and teachers who have direct personal experience of mindfulness practice and/or observations of their patients who completed the MBSR program. Conclusions: The authors conclude that with such rich evidence for its enhancement of health status and the parallel improvements in proactive self-care, mindfulness should be considered a fundamental principle in the evolving model of Participatory Medicine.
