Perceptions of Confidentiality Violations Among Psychologists

This study explored psychologists' perceptions of confidentiality violations. One hundred ninety-five psychologists answered questionnaires about a vignette regarding a male therapist accused of violating the confidentiality of a female client. The vignette varied on the following variables: (a) Confidential information was conveyed to either an insurance company or another client, (b) the therapist's account of the violation included either an excuse or a justification, and (c) scapegoating was included or not included in the account. The insurance condition and excuse condition produced more lenient judgments of the violation. However, excuses elicited more negative judgments of the therapist. Scapegoating generally elicited more negative judgments. Differences in the recipient of confidential information and the accounts given for violations have an impact on psychologists' perceptions of confidentiality violations.
Quels facteurs explicatifs du burnout et du bien-être subjectif ? Déterminants psychologiques, sociaux et organisationnels auprès des cadres à responsabilités et élaboration d'un modèle

Notre societe accorde au travail une importance considerable, il constitue le socle de l'identite, promesse d'accomplissement et de realisation de soi. Pourtant aujourd'hui, les cadres sont fatigues d'en faire toujours plus et d'aller au-dela de leurs limites. L'evolution de nos organisations a instaure des nouveaux modes d'organisation du travail tels que le management par objectifs, la gestion previsionnelle des emplois et des competences, des politiques d'individualisation, une evaluation continue des personnes et des process. Les exigences du travail que sont la quantite et la complexite du travail, le pression temporelle, liees a une injustice organisationnelle et un soutien au travail defaillants vont generer une reduction des ressources psychiques et physiques menant a l'epuisement emotionnel, voire a l'effondrement. Partant de ce constat, les resultats mis en evidence dans cette etude permettent d'insister sur un ensemble de determinants de la sante et sur les influences imbriquees de ces facteurs. Les differents facteurs qui induisent les problemes de sante au travail et sur lesquels il faudra agir concernent la charge de travail, l'organisation du travail et les pressions liees au temps, a la multiplicite des tâches et, en particulier, le manque de soutien et de feed-back positifs. Il est important aussi d'insister sur la place de la satisfaction des besoins. Chaque besoin fondamental doit pouvoir etre satisfait sous peine de desequilibre de la personne et d'atteinte a sa vitalite et a son existence. Une atteint a un niveau supra-ordonne (estime, reconnaissance,.) dans les contextes organisationnels neoliberaux desequilibre fondamentalement la personne qui vit par et pour son organisation. Nous avons montre egalement l'importance de developper une justice organisationnelle forte notamment en termes des procedures et d'informations.
Analyzing incoming workload in Cloud business services

A recent trend, movement of software applications to Cloud, provides among numerous benefits, an important model for infrastructure cost reduction using the pay-as-you-go concept. In our experiments, we noticed that software distribution may significantly influence cost benefits achieved in Cloud. Software distribution optimization requires a continuous information influx on key metrics characterizing incoming workload. In this paper we propose a method for modeling workloads of business applications characterized by nonuniform distribution over the day. Two important properties are described: (1) modeling and forecasting repeatable patterns observed in the business context, and (2) modeling the inter-arrival time distribution of service requests. While former is important for constructing automated capacity planning controllers, latter is required for describing the amount of traffic variability. We analyzed these properties on a two-month workload collected from a production business services used by several thousand customers in retail domain in Croatia. Based on this analysis, we propose a high-level design of a quality of service controller applicable to business services in cloud environment.
Multi-tenant mobility control in Small Cells as a Service

Small Cell as a Service (SCaaS) is envisaged as a solution to facilitate the provisioning of shared radio access capacity to mobile operators in areas where dedicated per-operator deployments may be impractical, typically highly densified scenarios such as stadiums, malls, office buildings, etc. In this context, this paper firstly establishes a reference framework for SCaaS provisioning from the Radio Access Network (RAN) perspective, including management architecture and functionalities as well as Service Level Agreement aspects impacting on the way that the shared RAN is deployed and operated. Then, the implications of multi-tenancy on mobility control are analysed in order to delineate the impact on Radio Resource Management (RRM) and Self-Organizing Network (SON) functionalities as a result of the emergence of this novel business model.
Effects of human placental lactogen on the expression of CD163 and CD14 on human monocytes in culture

The effect of human placental lactogen (hPL), a member of the somatomammotrophin family, on the regulation of the scavenger receptor molecules CD14 and CD163 on human monocytes cultured for 48h was investigated. Cells were cultured in the presence or absence of the hormone and also in the presence or absence of IFN‐γ and dexamethasone. Monocytes cultured in the presence of hPL showed a significant increase in the expression of CD14 in both males and females compared to background. When IFN‐γ and dexamethasone were added to the cultures, CD14 expression was decreased and was not rescued by the presence of hPL. hPL alone had no effect on the expression of CD163 on cultured monocytes from either gender, although cells cultured in the presence of IFN‐γ and dexamethasone showed a profound increase in their expression of CD163. This expression was augmented further by the presence of hPL in the cultures over a 48‐h period. These results support the hypothesis of a potential role of this hormone in the regulation of the innate immune response.
Comparative electrophysiological and hemodynamic measures of neural activation during memory‐retrieval

The spatial and temporal characteristics of the brain processes underlying memory retrieval were studied with both event‐related potentials (ERP) and positron emission tomography (PET) techniques. Subjects studied lists of 20 words and then performed episodic (old/new judgment) or semantic (living/nonliving decision) retrieval tasks on multiple four‐item test lists, each lasting 10 sec. The PET and ERP measurements at test were assessed in relation to both the task (episodic vs. semantic) and the item (old vs. new or living vs. nonliving). Episodic retrieval was associated with increased blood flow in the right frontal lobe (Brodmann Area 10) and a sustained, slowly developing positive ERP shift recorded from the right frontopolar scalp. Semantic retrieval was associated with increased blood flow in the left frontal (Area 45) and temporal (Area 21) lobes but no clear ERP concomitant. The two retrieval tasks also differed from each other in the ERPs to single items in an early (300–500 ms) time window. Item‐related comparisons yielded convergent results mainly if the retrieved information was relevant to the given task (e.g., old/new items during episodic retrieval and living/nonliving items during semantic retrieval). Episodically retrieved old items were associated with increased blood flow in the left medial temporal lobe and a transient increase in the amplitude of the late positive component (500–700 ms) of the ERP. Semantically retrieved living items were associated with increased blood flow in the left frontal cortex and anterior cingulate and a transient late frontal slow wave (700–1,500 ms) in the ERPs. These results indicate that the brain regions engaged in memory retrieval are active in either a sustained or transient manner. They map task‐related processes to sustained and item‐related processes to transient neural activity. But they also suggest that task‐related factors can transiently affect early stages of item processing. Hum. Brain Mapping 13:104–123, 2001. © 2001 Wiley‐Liss, Inc.
Dysbindin-containing complexes and their proposed functions in brain: from zero to (too) many in a decade

Dysbindin (also known as dysbindin-1 or dystrobrevin-binding protein 1) was identified 10 years ago as a ubiquitously expressed protein of unknown function. In the following years, the protein and its encoding gene, DTNBP1, have become the focus of intensive research owing to genetic and histopathological evidence suggesting a potential role in the pathogenesis of schizophrenia. In this review, we discuss published results demonstrating that dysbindin function is required for normal physiology of the mammalian central nervous system. In tissues other than brain and in non-neuronal cell types, the protein has been characterized as a stable component of a multi-subunit complex, named BLOC-1 (biogenesis of lysosome-related organelles complex-1), which has been implicated in intracellular protein trafficking and the biogenesis of specialized organelles of the endosomal–lysosomal system. In the brain, however, dysbindin has been proposed to associate into multiple complexes with alternative binding partners, and to play a surprisingly wide variety of functions including transcriptional regulation, neurite and dendritic spine formation, synaptic vesicle biogenesis and exocytosis, and trafficking of glutamate and dopamine receptors. This puzzling array of molecular and functional properties ascribed to the dysbindin protein from brain underscores the need of further research aimed at ascertaining its biological significance in health and disease.
Functional Correlates of Midline Brain Volume Loss in Chronic Traumatic Brain Injury

Abstract Traumatic brain injury (TBI) is associated with long-term changes in daily life functioning, yet the neuroanatomical correlates of these changes are poorly understood. This study related outcome assessed across several domains to brain structure derived from quantitative magnetic resonance imaging (MRI). Sixty individuals spanning a wide range of TBI severity participated 1-year post-injury as part of the Toronto TBI study. Volumetric data over 38 brain regions were derived from high resolution T1-weighted MRI scans. Functioning was assessed with a battery of self- and significant-other rated measures. Multivariate analysis (partial least squares) was used to identify shared variance between the neuroimaging and outcome measures. TBI was associated with item endorsement on outcome questionnaires without strong evidence for severity or focal lesion effects. Prefrontal midline, cingulate, medial temporal, right inferior parietal and basal ganglia/thalamic volumes were associated with measures of initiative, energization, and physical complaints. In the chronic stage of TBI, self-initiation, energization, and physical complaints related to a specific pattern of volume loss in midline and lateral regions known to be involved in motivation, apathy, and attention. These results suggest that crucial functional changes in chronic TBI may be associated with volume loss in established midline-frontal and attentional circuits. (JINS, 2015, 21, 650–655)
Treatment decisions based on scalar and functional baseline covariates

The amount and complexity of patient‐level data being collected in randomized‐controlled trials offer both opportunities and challenges for developing personalized rules for assigning treatment for a given disease or ailment. For example, trials examining treatments for major depressive disorder are not only collecting typical baseline data such as age, gender, or scores on various tests, but also data that measure the structure and function of the brain such as images from magnetic resonance imaging (MRI), functional MRI (fMRI), or electroencephalography (EEG). These latter types of data have an inherent structure and may be considered as functional data. We propose an approach that uses baseline covariates, both scalars and functions, to aid in the selection of an optimal treatment. In addition to providing information on which treatment should be selected for a new patient, the estimated regime has the potential to provide insight into the relationship between treatment response and the set of baseline covariates. Our approach can be viewed as an extension of “advantage learning” to include both scalar and functional covariates. We describe our method and how to implement it using existing software. Empirical performance of our method is evaluated with simulated data in a variety of settings and also applied to data arising from a study of patients with major depressive disorder from whom baseline scalar covariates as well as functional data from EEG are available.
Investigating the Periocular-Based Face Recognition Across Gender Transformation

This paper introduces a novel face recognition problem domain: the medically altered face for gender transformation. A data set of >1.2 million face images was constructed from wild videos obtained from You Tube of 38 subjects undergoing hormone replacement therapy (HRT) for gender transformation over a period of several months to three years. The HRT achieves gender transformation by severely altering the balance of sex hormones, which causes changes in the physical appearance of the face and body. This paper explores that the impact of face changes due to hormone manipulation and its ability to disguise the face and hence, its ability to effect match rates. Face disguise is achieved organically as hormone manipulation causes pathological changes to the body resulting in a modification of face appearance. This paper analyzes and evaluates face components versus full face algorithms in an attempt to identify regions of the face that are resilient to the HRT process. The experiments reveal that periocular face components using simple texture-based face matchers, local binary patterns, histogram of gradients, and patch-based local binary patterns out performs matching against the full face. Furthermore, the experiments reveal that a fusion of the periocular using one of the simple texture-based approaches (patched-based local binary patterns) out performs two Commercial Off The Shelf Systems full face systems: 1) PittPatt SDK and 2) Cognetic FaceVACs v8.5. The evaluated periocular-fused patch-based face matcher outperforms PittPatt SDK v5.2. 2 by 76.83% and Cognetic FaceVACS v8.5 by 56.23% for rank-1 accuracy.
Cystatin C and estimates of renal function: searching for a better measure of kidney function in diabetic patients.

BACKGROUND Early identification of impairment in renal function is crucial in diabetic patients. Serum cystatin C may be the most sensitive indicator of glomerular filtration rate (GFR) in the clinical setting. METHODS We compared cystatin C with creatinine, the Cockcroft-Gault (C-G) formula, and the Modification of Diet in Renal Disease (MDRD) study equation for the assessment of early decreased renal function in 288 diabetic patients (125 type 1, 163 type 2) with renal impairment [GFR: 4-222 mL x min(-1) x (1.73 m(2))(-1)]. Relationships of cystatin C, creatinine, and iohexol clearance were linearized by plotting their reciprocals in a simple regression model. Diagnostic efficiency was calculated from ROC curves. RESULTS In this study population, cystatin C (P = 0.0013) was better correlated with GFR (r = 0.857) than were creatinine (r = 0.772), C-G (r = 0.750), and MDRD (r = 0.806), a result replicated in patients with normal renal function (P = 0.023, type 1; P = 0.011, type 2), but not in those with decreased GFR. Mean cystatin C concentrations showed step-by-step statistically significant increases as GFR decreased, allowing very early detection of reduction in renal function. At 90 mL x min(-1) x (1.73 m(2))(-1) and 75 mL x min(-1) x (1.73 m(2))(-1) cut-points, diagnostic efficiencies of cystatin C (89% and 92%) were better than those of the other variables (79%-82% and 85%-86%, respectively; P = 0.01). CONCLUSIONS All data supported the value of serum cystatin C compared with conventional estimates based on serum creatinine measurement for detecting very early reduction of renal function. Use of cystatin C to measure renal function will optimize early detection, prevention, and treatment strategies for diabetic nephropathy.
Y...¿Dónde está la resilencia? una reflexión conceptual

After critically reviewing the historical development of the concept of resilience in psychology and psychiatry, we propose not to consider resilience as a psychological variable in itself. Rather, we suggest that all persons who present an unexpected outcome in face of a given adverse situation should be considered resilient, regardless of the causes of that outcome. We further propose a distinction among protective factors, recovery factors, and behavioral control factors. Finally, implications of these ideas for research are discussed.
Model-Free Inference for ChIP-Seq Data

Due to its higher resolution mapping and stronger ChIP enrichment signals, ChIP-seq tends to replace ChIP-chip technology in studying genome-wide protein-DNA interactions, while the massive digital ChIP-seq data present new challenges to statisticians. To date, most methods proposed in the literature for ChIP-seq data analysis are model based, however, finding a single model workable for all datasets is impossible, given the complexity of biological systems and variations generated in the sequencing process. In this paper, we present a model-free approach, the so-called MICS (Model-free Inference for ChIP-Seq), for ChIP-seq data analysis. MICS has a few advantages over the existing methods: Firstly, MICS avoids assumptions for the data distribution, and thus it maintains high power even when model assumptions for the data are violated. Secondly, MICS employs a simulation-based method in estimating the false discovery rate. Since the simulation-based method works independently of ChIP samples, MICS can perform robustly to variety of ChIP samples; it can produce accurate identification of peak regions, even for those where the enrichment is weak. Thirdly, MICS is very efficient in computation, which takes only a few seconds on a personal computer for a reasonably large dataset. In this paper, we also present a simple semi-empirical method for simulating ChIP-seq data, which allows a better assessment of performance of different approaches for ChIP-seq data analysis. MICS is compared with several existing methods, including MACS, CCAT, PICS, BayesPeak and QuEST, based on real and simulated datasets. The numerical results indicate that MICS can outperform others.

Identification and Characterization of Compounds That Potentiate NT-3-Mediated Trk Receptor Activity

Neurotrophins are a family of secreted proteins that play an important role in the development, differentiation, and survival of neurons. Studies also suggest that aberrant neurotrophin signaling may play a role in processes underlying disease states such as schizophrenia, Alzheimer's disease, and depression. Whereas the development of agents that selectively stimulate neurotrophin signaling has proven to be difficult, compounds have been identified that potentiate neurotrophin 3 (NT-3)-mediated activation of trk A. In the present studies, we extend those initial observations to identify compounds that also potentiate NT-3-mediated activation of trk B. Compound potentiation of NT-3 was observed using several readouts of transfected and endogenous trk receptor activity, including trk receptor phosphorylation, mitogen-activated protein kinase phosphorylation, reporter assay activity (β-lactamase and luciferase), cell survival and neurite extension assays. Studies using chimeric trk receptors demonstrated that the extracellular domain is essential for compound potentiation and rule out interaction with intracellular signaling molecules as a mechanism of compound activity. Thus, the present studies demonstrate that trk B receptor activity can be potentiated by small-molecule compounds via the extracellular domain of the receptor and provide reagents for further evaluating the role of NT-3-mediated trk A and trk B activity in vivo.

Sensemaking on the Shop Floor: Narratives of Knowledge in Organizations*

This paper explores the role of narratives in organizational inquiry and knowledge work. Following the tenets of the phenomenological method, the paper digs into the 'life world' of organizations in order to capture the taken for granted stream of everyday routines, interaction, and events that constitute both individual and social practices. An empirical case study examines the narrative-based processes of sensemaking and knowledge acquisition in the setting of a traditional pressing plant at Fiat Auto, Italy. The focus of analysis is on how a best performing team engages in the resolution of disruptive occurrences on the shop floor. Through the deconstruction of narratives underlying problem-solving activities, the case identifies a distinctive mode of investigation conceptualized as 'detective stories'. The detective's method highlights the interplay between time and narrative in shaping the interconnected processes of organizational knowledge creation, utilization, and institutionalization. More generally, the findings of the paper stress the importance of conjectural knowledge and common-sensical wisdom in the everyday life of organizations. Copyright 2003 Blackwell Science Asia Pty.

The Effects of Social Media on College Students

As social media sites continue to grow in popularity, it is our premise that technology is a vital part in today’s student success equation. This descriptive, exploratory research study drew a random sample (N=48) of males (n=26) and females (n=22) who were administered a student perception questionnaire on how social media affects college students. Thirty-five percent of the participants were undergraduates and 65% were graduate students, studying at Johnson & Wales University. Thirty-one percent of participants have full-time jobs, 30% have part-time jobs and 39% do not have jobs. The results of the survey questionnaire indicate that 45% of the sample admitted that they spent 6-8 hours per day checking social media sites, while 23% spent more than 8 hours; 20% spent 2-4 hours and only 12% spent less than 2 hours on this task. Results indicate while most college students use social media and spend many hours checking social media sites, there was a negative aspect to college students’ use of social media.
