Comparison of Features of Online Journals and Databases
Authors: Punchihewa CND
Published: April 2015

The objective of the study was to examine and make a comparison of the features of online journals and databases available at the Library, University of Moratuwa during the year 2006. A total of nineteen online resources including nine online databases and ten online journals were examined. The systems were assessed under two criteria, the user friendliness and the functionality. The user friendliness features were assessed under the design of the web pages and the type of the interface, personalisation and database selection. Access and retrieval of information, results manipulation and availability of help menu were considered under the functionality features. Boolean operators, phrase searching, field specific searching, wildcard and truncation were observed as common retrieval features. The interpretation and implementation of these features were different among the systems. The greatest differences were found in the area of query formulation. Lateral searching, reference links and searching with table of contents were identified as the unique features.Journal of the University Librarians Association of Sri Lanka.

Extended Roles and Responsibilities of Library Association Web Sites
Authors: Gamage Ruwan
Published: April 2015

Library associations have used Web based mediums from a long time to disseminate information to their membership. However, most of these sites were static, and were not updated frequently. This is mainly due to the lack of time & user friendly technologies. Present Web 2.0 technologies have enabled easy designing and maintenance of Web sites. This paper mainly introduce such technologies and enabled features employed in redesigning the University Librarians Association (ULA) of Sri Lanka web site. It also discuss some changes concurrently taken place in a few other library association web sites. It is evident that Web site renovation should be a well planned process, and that due to addition of new services and features, associations can climb up to higher levels of user interaction.Journal of the University Librarians Association of Sri Lanka.

Why Medical Students Keep Books Overdue: A study at the University of Jaffna
Authors: Murugathas Komathy
Published: April 2015

In the University of Jaffna Medical Library, one hundred and twenty randomly selected medical students who had overdue books were surveyed using a questionnaire with the objective of identifying reasons for keeping borrowed library books overdue; to find out how they perceive the eight given measures against overdue books; and for seeking methods to reduce number of overdue books. A majority of the books which were overdue had been borrowed for reading for clinical classes. Being overdue was fairly high in the subject of orthopedics, followed by microbiology. Results revealed that the major reason for keeping books overdue is students being unable to finish reading. The books on high demand were overdue since the numbers of copies available in the library were not enough to satisfy students' needs. Students were in favor of sending reminder notices as a means of discouraging overdue books, followed by providing renewal opportunities. Students suggested increasing number of copies of demand books, extend the opening hours of the library and extend the loan period as feasible solutions. The need for an extended loan period and increasing the number of copies will require further investigation. Purchasing e-books is another alternative for some textbooks.Journal of the University Librarians Association of Sri Lanka. Vol.13 (Issue 1). 2009 1-11
Imaging for assessment of treatment response in hepatocellular carcinoma: Current update
Authors: Hayano Koichi , Lee Sang Ho , Sahani Dushyant V
Published: April 2015

Morphologic methods such as the Response Evaluation Criteria in Solid Tumors (RECIST) are considered as the gold standard for response assessment in the management of cancer. However, with the increasing clinical use of antineoplastic cytostatic agents and locoregional interventional therapies in hepatocellular carcinoma (HCC), conventional morphologic methods are confronting limitations in response assessment. Thus, there is an increasing interest in new imaging methods for response assessment, which can evaluate tumor biology such as vascular physiology, fibrosis, necrosis, and metabolism. In this review, we discuss various novel imaging methods for response assessment and compare them with the conventional ones in HCC.

Published: April 2015

Neuroblastoma is the third common tumor in children. Imaging plays an important role in the diagnosis, staging, treatment planning, response evaluation and in follow-up of a case of Neuroblastoma. The International Neuroblastoma Risk Group task force has recently introduced an imaging-based staging system and laid down guidelines for uniform reporting of imaging studies. This review is an update on imaging in neuroblastoma, with emphasis on these guidelines.
Osmotic myelinolysis: Does extrapontine myelinolysis precede central pontine myelinolysis? Report of two cases and review of literature
Authors: Babanrao Sabale Avinash , Prahladan Anil , Kalidos Kalirajan , Ramachandran Krishnankutty
Published: April 2015

Osmotic myelinolysis is an acute, rare, demyelinating process. After the initial description of the condition by Adam and colleagues in 1959, many case series have been published describing the central and extrapontine myelinolysis. Imaging has a definitive role in establishing the diagnosis of osmotic myelinolysis in vivo and diffusion-weighted imaging reveals earliest changes in affected brain parenchyma. We report two cases of patients with proven malignancy who developed extrapontine myelinolysis after treatment for hyponatremia and progressed to central pontine myelinolysis within a week. This was confirmed with magnetic resonance (MR) imaging and clinical assessment. This temporal progression of MR features, especially on diffusion-weighted imaging, from extrapontine to central pontine myelinolysis in osmotic injury has not been described in literature to the best of our knowledge. An early MRI of the brain in suspected/high-risk cases of osmotic myelinolysis may show features of extrapontine myelinolysis in the form of restricted diffusion in bilateral basal ganglia and may serve as a guide for predicting progression, prognosticating and deciding further treatment of pontine myelinolysis. We propose that in a significant number of cases, central pontine myelinolysis may be predicted by doing an early MRI of the brain with diffusion-weighted imaging, when extrapontine symptoms start to develop. This can potentially increase the window period and possibilities for therapeutic intervention and may even help in prevention.
Hilar cholangiocarcinoma: Cross sectional evaluation of disease spectrum
Authors: Mahajan Mangal S , Moorthy Srikanth , Karumathil Sreekumar P , Rajeshkannan R , Pothera Ramchandran
Published: April 2015

Although hilar cholangiocarcinoma is relatively rare, it can be diagnosed on imaging by identifying its typical pattern. In most cases, the tumor appears to be centered on the right or left hepatic duct with involvement of the ipsilateral portal vein, atrophy of hepatic lobe on that side, and invasion of adjacent liver parenchyma. Multi-detector computed tomography (MDCT) and magnetic resonance cholangiopancreatography (MRCP) are commonly used imaging modalities to assess the longitudinal and horizontal spread of tumor.
Concurrent nonfunctional paraganglioma of the retroperitoneum and urinary bladder: A case report with literature review
Authors: Sherwani Poonam , Anand Rama , Narula Mahender Kaur , Siddiqui Azaz Akhtar , Aggarwal Shilpi
Published: April 2015

Paragangliomas are the neuroendocrine tumors which arise from the chromaffin cell. Tumors arising from the adrenal medulla are known as pheochromocytomas, while others originating from the extra-adrenal site are known as extra-adrenal paragangliomas. Paraganglioma can be multifocal which can arise synchronously or metachronously. Paragangliomas are less functionally active than the pheochromocytomas; they secrete noradrenaline and rarely dopamine, while adrenal pheochromocytomas secrete adrenaline or nor-adrenaline. Nonfunctional multifocal paragangliomas are very rare. We report a case of a 45-year-old female with multifocal nonfunctional paragangliomas of the retroperitoneum and urinarybladder which were surgically removed, and the diagnosis was confirmed on histopathology.
Enhanced patient care through collaborative team play: An orthodontist and an OMF.Radiologist’s collective perspective
Authors: Yadav Sumit , Tadinada Aditya
Published: April 2015

The overarching theme of patient-centric care should serve as the fundamental basis for our treatment plans. Treatment plans that best utilize knowledge; training and technology must be developed on current evidence that rests on soundly researched principles. In orthodontics, the evolution of cone beam computed tomography as a new three-dimensional imaging modality has brought a paradigm shift in the radiographic evaluation of the maxillofacial structures. However, the coming of new technology does not warrant its use in routine practice and tight imaging protocols must be developed to include and promote the evidence-based patient-centric approach. This principle is best approached if the effort is a collaborative one. Collaboration between all the disciplines that contribute to patient care must act as a unified force to deliver superior care. In this editorial, we present a successful collaborative effort between orthodontics and oral and maxillofacial radiology that have engaged in collaborative efforts to deliver superior patient care, better predoctoral and postdoctoral training programs and how this effort has yielded excellent contribution to research.
Plaque accumulation and Streptococcus mutans levels around self-ligating bracket clips and elastomeric modules: A randomized controlled trial
Authors: Fadia Dhaval , Vandekar Meghna , Vaid Nikhilesh , Doshi Viraj
Published: April 2015

Aim

To determine the effect of two different ligating systems that is, elastomeric modules and self-ligating (SL) bracket systems (Smartclip - 3M Unitek) with respect to harboring bacterial plaque in fixed orthodontic treatment.

Objectives

To assess, evaluate, and compare the amount of plaque accumulation and Streptococcus mutans colonization around elastomeric ligation and SL clips in the smart clip appliance.

Materials and Methods

A total of 111 orthodontic patients scheduled for fixed orthodontic treatments were selected for this split maxillary arch study. All the patients were bonded with smart-clip (3M Unitek) SL brackets, and the wire was placed into the bracket slots, on the randomly selected hemi arch, elastomeric modules were placed for the study to be conducted. Microbial and periodontal plaque accumulation was recorded at 3-time intervals post ligation. Plaque index-by Silness and Loe, modified Quigely Hein index, bleeding on probing were evaluated, and biofilm was collected from the tooth surface after 30 days and placed in petri dishes containing Mitis Salivarius agar for bacterial culturing.

Result

It was observed that the side where ligation was done with elastomeric modules accumulated more plaque and increase in S. mutans colony forming units as compared to the side without external ligation (P < 0.05).

Conclusion

Reduced bacterial colonization and better plaque control was seen with SL orthodontic bracket appliance system as compared to conventional ligation method.

BIR Pipeline for Preparation of Phylogenomic Data
Authors: Kumar Surendra , Krabberød Anders K. , Neumann Ralf S. , Michalickova Katerina , Zhao Sen , Zhang Xiaoli , Shalchian-Tabrizi Kamran
Published: April 2015

We present a pipeline named BIR ( Blast, Identify and Realign) developed for phylogenomic analyses. BIR is intended for the identification of gene sequences applicable for phylogenomic inference. The pipeline allows users to apply their own manually curated sequence alignments (seed) in search for homologous genes in sequence databases and available genomes. BIR automatically adds the identified sequences from these databases to the seed alignments and reconstruct a phylogenetic tree from each. The BIR pipeline is an efficient tool for the identification of orthologous gene copies because it expands user-defined sequence alignments and conducts massive parallel phylogenetic reconstruction. The application is also particularly useful for large-scale sequencing projects that require management of a large number of single-gene alignments for gene comparison, functional annotation, and evolutionary analyses.

An elementary approach to dessins d’enfants and the Grothendieck–Teichmüller group
Authors: Guillot Pierre
Published: April 2015

We give an account of the theory of dessins d'enfants which is both elementary and self-contained. We describe the equivalence of many categories (graphs embedded nicely on surfaces, finite sets with certain permutations, certain field extensions, and some classes of algebraic curves), some of which are naturally endowed with an action of the absolute Galois group of the rational field. We prove that the action is faithful. Eventually we prove that Gal

(\overline {\mathbb Q}/\mathbb Q)

embeds into the Grothendieck-Teichmüller group

\widehat {\mathcal {GT}_0}

introduced by Drinfeld. There are explicit approximations of

\widehat {\mathcal {GT}_0}

by finite groups, and we hope to encourage computations in this area.

Our treatment includes a result which has not appeared in the literature yet: the action of Gal

(\overline {\mathbb Q}/\mathbb Q)

on the subset of
regular
dessins – that is, those exhibiting maximal symmetry – is also faithful.
On invariant Schreier structures
Authors: Cannizzo Jan
Published: April 2015

Schreier graphs, which possess both a graph structure and a
Schreier structure
(an edge-labeling by the generators of a group), are objects of fundamental importance in group theory and geometry. We study the Schreier structures with which unlabeled graphs may be endowed, with emphasis on structures which are
invariant
in some sense (e.g. conjugation-invariant, or
sofic
). We give proofs of a number of “folklore” results, such as that every regular graph of even degree admits a Schreier structure, and show that, under mild assumptions, the space of invariant Schreier structures over a given invariant graph structure is very large, in that it contains uncountably many ergodic measures. Our work is directly connected to the theory of
invariant random subgroups
, a field which has recently attracted a great deal of attention.
Schauder estimate for solutions of Poisson’s equation with Neumann boundary condition
Authors: Nardi Giacomo
Published: April 2015

We consider here the Neumann problem for the Laplace operator and prove an existence result in the Hölder spaces and obtain Schauder estimates. According to our knowledge this result is not explicitly proved in the several works devoted to Schauder theory, where similar theorems are proved for the Dirichlet and oblique derivative problems. Our contribution is to make explicit the existence and the estimate for the Neumann problem.
Infancia, juego y fantasía en el mundo digital
Authors: Andreu Bertran Lluís
Published: April 2015

Partiremos de preguntas que sus respuestas ofrezcan múltiples posibilidades  y abran un debate que su unificación obtenga una respuesta lo más rica posible de contenido. Así pues ¿Quien pone las normas para jugar en el mundo digital de los niños? ¿Quien marca el uso y delimita el mundo digital para que el niño juegue, aprenda o se comunique? El niño se relaciona con el mundo digital: juegos, redes sociales, navegar,…, con unas reglas que establecen un compromiso en el momento de participar y aquellos que no las comportan,  lo conducen a un “libre” movimiento asociativo, cognitivo y emocional.  Así pues, el niño ¿“Juega con el ordenador o está y crece con el ordenador”? Delante de la ausencia de reglas explícitas y reconocidas nos equivocaríamos si pensamos que ello implica obligatoriamente la ausencia de toda regla. Esta regla universal de la que sospechamos que existe en todo niño, podría figurar o bien en su “yo”, o bien en su fantasía; posturas muy diferenciadas y de consecuencias diversas. ¿Seria arriesgado manifestar que para un niño “juego es juego” prescindiendo del origen de las reglas? ¿Nos encontramos pues ante la disyuntiva de reglas objetivas o subjetivas en su elaboración y comprensión? ¿Habrá que ofrecerle el máximo de “imputs” de objetividad para neutralizar, reconducir o vetar la subjetividad y fantasía que le comporta la interacción, en el peor de los casos perversa, con el mundo digital? Se nos hace fundamental el pensar que la protección del niño ante el mundo digital se realizará en todo aquello que él pueda entender y asumir como regla desde su “yo”. En tener en cuenta que desde su “yo” y el “no-yo” existe un espacio abierto de fantasía que puede aportar riqueza pero también muchos  peligros para él. Si se le abandona a su suerte y la interacción se realiza desde la posición del “no-yo”, el peligro que corre de encontrarse “solo” en el mundo digital, sin nada que lo contenga ni que lo proteja, podrá tener consecuencias de crecimiento y evolución, con daños incalculables.

Non-parametric and least squares Langley plot methods
Authors: Kiedron P. W. , Michalsky J. J.
Published: April 2015

Abstract. Langley plots are used to calibrate sun radiometers primarily for the measurement of the aerosol component of the atmosphere that attenuates (scatters and absorbs) incoming direct solar radiation. In principle, the calibration of a sun radiometer is a straightforward application of the Bouguer–Lambert–Beer law V=V>/i>0e−τ ·m, where a plot of ln (V) voltage vs. m air mass yields a straight line with intercept ln (V0). This ln (V0) subsequently can be used to solve for τ for any measurement of V and calculation of m. This calibration works well on some high mountain sites, but the application of the Langley plot calibration technique is more complicated at other, more interesting, locales. This paper is concerned with ferreting out calibrations at difficult sites and examining and comparing a number of conventional and non-conventional methods for obtaining successful Langley plots. The eleven techniques discussed indicate that both least squares and various non-parametric techniques produce satisfactory calibrations with no significant differences among them when the time series of ln (V0)'s are smoothed and interpolated with median and mean moving window filters.
Evaluation of WRF model seasonal forecasts for tropical region of Singapore
Authors: Singh J. , Yeo K. , Liu X. , Hosseini R. , Kalagnanam J. R.
Published: April 2015

Abstract. The Weather and Research Forecast (WRF) model is evaluated for the monsoon and inter-monsoon seasons over the tropical region of Singapore. The model configuration, physical parameterizations and performance results are described in this paper. In addition to the ready-to-use data available with the WRF model, the model configuration includes high resolution MODIS land use (500 m horizontal resolution) and JPL-NASA sea surface temperature (1 km horizontal resolution) data. The model evaluation is performed against near surface observations for temperature, relative humidity, wind speed and direction, available from a dense network of weather monitoring stations across Singapore. It is found that the high resolution data sets bring significant improvement in the model forecasts. The results also indicate that the model forecasts are more accurate in the monsoon seasons compared to the inter-monsoon seasons.
Sensitivity of airborne geophysical data to sublacustrine and near-surface permafrost thaw
Authors: Minsley B. J. , Wellman T. P. , Walvoord M. A. , Revil A.
Published: April 2015

Abstract. A coupled hydrogeophysical forward and inverse modeling approach is developed to illustrate the ability of frequency-domain airborne electromagnetic (AEM) data to characterize subsurface physical properties associated with sublacustrine permafrost thaw during lake-talik formation. Numerical modeling scenarios are evaluated that consider non-isothermal hydrologic responses to variable forcing from different lake depths and for different hydrologic gradients. A novel physical property relationship connects the dynamic distribution of electrical resistivity to ice saturation and temperature outputs from the SUTRA groundwater simulator with freeze–thaw physics. The influence of lithology on electrical resistivity is controlled by a surface conduction term in the physical property relationship. Resistivity models, which reflect changes in subsurface conditions, are used as inputs to simulate AEM data in order to explore the sensitivity of geophysical observations to permafrost thaw. Simulations of sublacustrine talik formation over a 1000-year period are modeled after conditions found in the Yukon Flats, Alaska. Synthetic AEM data are analyzed with a Bayesian Markov chain Monte Carlo algorithm that quantifies geophysical parameter uncertainty and resolution. Major lithological and permafrost features are well resolved by AEM data in the examples considered. The subtle geometry of partial ice saturation beneath lakes during talik formation cannot be resolved using AEM data, but the gross characteristics of sub-lake resistivity models reflect bulk changes in ice content and can identify the presence of a talik. A final synthetic example compares AEM and ground-based electromagnetic responses for their ability to resolve shallow permafrost and thaw features in the upper 1–2 m below ground outside the lake margin.
Influence of weak layer heterogeneity and slab properties on slab tensile failure propensity and avalanche release area
Authors: Gaume J. , Chambon G. , Eckert N. , Naaim M. , Schweizer J.
Published: April 2015

Abstract. Dry-snow slab avalanches are generally caused by a sequence of fracture processes, including failure initiation in a weak snow layer underlying a cohesive slab followed by crack propagation within the weak layer (WL) and tensile fracture through the slab. During past decades, theoretical and experimental work has gradually increased our knowledge of the fracture process in snow. However, our limited understanding of crack propagation and fracture arrest propensity prevents the evaluation of avalanche release sizes and thus impedes hazard assessment. To address this issue, slab tensile failure propensity is examined using a mechanically based statistical model of the slab–WL system based on the finite element method. This model accounts for WL heterogeneity, stress redistribution by slab elasticity and possible tensile failure of the slab. Two types of avalanche release are distinguished in the simulations: (1) full-slope release if the heterogeneity is not sufficient to stop crack propagation and trigger a tensile failure within the slab; (2) partial-slope release if fracture arrest and slab tensile failure occur due to the WL heterogeneity. The probability of these two release types is presented as a function of the characteristics of WL heterogeneity and the slab. One of the main outcomes is that, for realistic values of the parameters, the tensile failure propensity is mainly influenced by slab properties. Hard and thick snow slabs are more prone to wide-scale crack propagation and thus lead to larger avalanches (full-slope release). In this case, the avalanche size is mainly influenced by topographical and morphological features such as rocks, trees, slope curvature and the spatial variability of the snow depth as often claimed in the literature.

My Car Is Worth What? Statistical Modeling for Predicting Value
Authors: Schloemer Cathy G.
Published: April 2015

During Algebra 2, students typically study statistical modeling involving linear, exponential, and quadratic functions. Students explore each type of function separately using verbal descriptions, ordered pairs, graphing, and equations. Calculator technology supports and extends student learning as teachers encourage both conceptual understanding of each model (constant increase or decrease, percentage increase or decrease, parabolic increase or decrease) and procedural competence (identifying, calculating, explaining, and using models). After some practice with data sets that are not already labeled as linear, exponential, or quadratic, students move to raw data sets, develop their own models, and justify their choices.

After the Great War: Nationalism, Degenerationism and Mass Psychology
Authors: García-García Juan
Published: April 2015

This article explores the influence of psychological language and discourses on the contemporary view of nationalism, an issue that has only begun to be studied in recent years (García-García, 2013; Sluga, 2006). On this occasion, the author focuses on two currents or schools that contributed decisively to the new view of nationalism after the Great War: first, degenerationist medicine and psychiatry, highly accepted in the European social and political debate since the late 19th century; second, and no less penetrating, the crowd or mass psychology of Taine, Tarde, Sighele, and, above all, Gustave Le Bon. After the Great War, as we shall see, nationalism was often represented as a form of degeneration, or a barbarous and cruel regression to a prior stage of development, embodied by the masses. This discourse and rhetoric was to condition the area of study for generations. In fact, the voices of medicine, psychiatry and mass psychology have not disappeared from the debate and continue to directly and indirectly influence the academic and popular comprehension of nationalism.

Cardiovascular profile of defensive hostile women in a real stressful situation
Authors: Palmero Francisco , Guerrero Cristina , Gorayeb Ricardo
Published: April 2015

The main objective of this study was to analyze the impact of defensive hostility on cardiovascular response in a stressful situation. By measuring three of the most commonly used cardiovascular indexes (heart rate, systolic blood pressure and diastolic blood pressure) over three experimental phases (adaptation, task and recovery), the evolution of cardiovascular response was analyzed minute by minute throughout the entire experimental session, to check if the defensive hostility influences the cardiovascular function. Two scales were used: the Cook-Medley Composite Hostility Scale and the Marlowe-Crowne Social Desirability Scale. Based on the scores on these scales, there were formed four groups (high hostility and high defensiveness, high hostility and low defensiveness, low hostility and high defensiveness, and low hostility and low defensiveness). The stressful situation which was used in the task phase was a real academic examination (exam of the Psychology degree). The hypothesis was that cardiovascular response, activation and recovery, minute by minute, will be greater in hostile defensive women, with an intra-phase evolution profile characterized by maintenance or sensitization and slow recovery. Results show that defensive hostile individuals present the highest values in the physiological variables recorded, and less adaptive profiles.
Diseños de observación longitudinales: cambio intra-individual y diferencias inter-individuales observados durante la infancia
Authors: Escolano-Pérez Elena , Blanco-Villaseñor Angel
Published: April 2015

The study of change in repeated measures studies or longitudinal studies (cross-sectional and/or cross-sequential) is of considerable interest in the field of developmental psychology. Qualitative and quantitative measures of interindividual and intraindividual variability can be used to capture changes in cognitive development.

In the present study, through an empirical analysis of infant cognitive development, we investigate whether or not longitudinal (cross-sectional/cross-sequential) research designs can be used interchangeably with univariate or multivariate data analysis techniques. Methodologically, longitudinal data can be processed by univariate or multivariate analysis. However, the results and their interpretation may be different, even when the necessary statistical requirements are performed. Current statistical programs incorporate techniques to test for the presence of significant differences in data, regardless of whether these are evaluated by univariate or multivariate analysis.
The results of this study, conducted in infants studied at three time points (18, 21 and 24 months), show that both intraindividual and interindividual variability can be detected by repeated measures analyses.
The relationship between attachment styles and internalizing or externalizing symptoms in clinical and nonclinical adolescents

Published: April 2015

Studies regarding the relationship between attachment and psychopathology during adolescence have been performed separately for clinical and nonclinical adolescents and have used different assessment measures, which together might produce a methodological bias that increases the association between attachment and psychopathology. With the aim of avoiding this bias, the present study used identical measures to explore the relationship between attachment styles and internalizing or externalizing symptoms in clinical and nonclinical groups of adolescents. The sample consisted of  258 adolescents,129 clinical and 129 nonclinical,  aged between 14 and 18 years. The adolescents in each group were matched for age, gender, and socioeconomic status. Attachment was assessed using the CaMir Q-sort,(Pierrehumbert et al., 1996) and psychopathological symptoms were assessed by means of the Youth Self Report (YSR). The relationships between attachment and psychopathology were similar for clinical and nonclinical adolescents.  In both groups a preoccupied attachment style predicted internalizing and externalizing symptoms, somatic complaints, anxious-fearful behavior, verbal aggression, attention-seeking behavior, and thinking problems.  Compared to previous studies, this research has made it possible to identify broader, stronger, and more specific associations between preoccupied attachment style and psychopathological symptoms in adolescents.

The aim of this paper is to determine the relationship between climate and job satisfaction in the context of a public university. Data were collected from 318 administrative and technical employees. Multilevel analyses were conducted to test the cross level effects of climate −occurring at a level of administrative areas− and individual job satisfaction. Kopelman, Brief and Guzzo’s (1990) model provides a theoretical framework to show the relationships between climate and cognitive and affective states, such as job satisfaction. Results show that climate in administrative areas has a significant and possitive effect on job satisfaction, which has important implications for the development of innovative practices of human resources that encourage the welfare and commitment of employees on the building of a healthy and socially responsible organization.

This study investigated Psychology students’ interpersonal and social goals during their first year at university. In Study 1 we analyze the reliability and ran a confirmatory factor analysis of a 45-item questionnaire about different kinds of interpersonal motives. The sample was integrated by 610 first year college students from four consecutive courses. In a second study with another 140 students, beside the scale about interpersonal goals they completed a set of scales about their aspirations, psychological basic needs of autonomy, competence and relatedness, subjective wellbeing and perfectionism cognitions. Data from both studies showed that: a) Importance is given mainly to achievement, power, affiliation and overcoming personal problems goals; b) The presence of overcoming personal problems goals hindered adjustment, indicated by positive associations with all the perfectionism dimensions, and by negative association with subjective wellbeing and frustration of psychological needs. Our results could provide new insight about the profiles of psychological students and the consequences resulting from them for their academic guidance.

This study is the first phase of the formative research recommended in the Theory of Planned Behavior for the development of an intervention. Our aims are to identify modal beliefs about the performance of an exercise pattern in people with fibromyalgia, to test the items designed for direct evaluation of the predictive constructs and to explore their relationships with the behavior. We assessed 46 women with fibromyalgia. Content analysis showed more positive than negative consequences related to the performance of exercise guidelines (behavioral beliefs). Families and friends are the important referents (normative beliefs) and we identified facilitating and inhibiting factors in the performance of exercise behavior related to aspects of fibromyalgia (control beliefs) such as pain, fatigue and emotional state. The subjective norm scale showed the lowest internal consistency (α= .78). The results confirmed the sedentary lifestyle of the participants (previous behavior: Mean=3.67; rank=1-7) although they also suggested that participants intended to perform the behavior (Mean=5.67). The relationships between constructs are coherent with the theory, and support the relevance of applying it to the selected behavior and population.

Recent research has focused on behavioral correlates of temporal perspective (TP), suggesting that this individual difference has an influence on many health-related behaviors such as smoking and substance use, physical activity or life satisfaction. It is suggested that a consistently biased temporal orientation is associated with some psychiatric disorders and mediated by personality factors. However, few studies have explored the relationship between personality and TP from a psychobiological approach. The aim of the study was to examine the relationship between the Zimbardo Time Perspective Inventory (ZTPI) and Zuckerman-Kuhlman Personality Questionnaire (ZKPQ) in a sample of 196 undergraduate students through a multiple regression analyses. Results showed that: Past-Negative correlated positively with Neuroticism-Anxiety and negatively with Activity; Present Hedonistic correlated positively with Impulsive-Sensation Seeking and Sociability in a very high degree; and Future correlated positively with Neuroticism-Anxiety and Activity, and negatively with Impulsive-Sensation Seeking. Results are discussed in terms of the definition of both scales, their relationships and their implications in applied fields.

Introduction: The Hospital Anxiety and Depression Scale (HADS, Zigmond and Snaith, 1983) has become a popular clinical instrument designed to assess anxiety and depression. Evidence of HADS’ good screening properties applied to several samples has been found. HADS seems to be as good screening properties as other tools. Different studies in Spanish sample tested its psychometric properties, including also their cut-offs points, specificity and sensitivity. Our aim is to unify the results of studies in Spanish population specifying guidelines regarding their applicability and interpretation of their cut-off points. Material and method: bibliographic review. Results: 15 articles were selected, a) HADS confirms its optimal psychometric properties in different groups, b) HADS shows some variability in proposed cut-off points for different groups, c) A number of items shown weak factor loading and item-test. Discussion: These items should be reconsidered for new proposals of a shortened final scale. We suggest attending at distress total scale.

The present study evaluates how psychosocial group climate and personality affects burnout syndrome (BS) in teachers of infant, primary and secondary education. To do so questionnaires were administered to evaluate psychosocial climate, personality and burnout in a sample of 386 teachers. The study analyzes the relation between these variables and the extent to which the variables of climate and personality allow a predictive model of burnout to be established by means of multiple regression analysis. The results showed that both psychosocial climate (particularly the degree of disorganization) and personality (particularly emotional stability) influence burnout and, although climate factors seem to be better predictors of BS, the use of personality measurements increases the predictive capacity of the syndrome. Therefore, the joint use of these types of predictor increases our ability to establish models that can prevent BS in teaching environments
Predictores familiares de la violencia filio-parental: el papel de la disciplina familiar
Authors: Ibabe Izaskun
Published: April 2015

Child-to-parent violence is a social problem that is qualitatively different from other types of family violence, since adolescents direct their violence toward those who should represent authority and provide for their welfare. The main goal of this study was to analyze the role of family relationships and family discipline on violent and prosocial behavior by adolescents toward their parents. Participants were 585 children aged between 12 and 18 from 8 schools in the Autonomous Community of the Basque Country (Spain). Results show that family relationships based on affect and communication are those that promote prosocial behaviors by children and reduce their violent behaviors at home. However, power-assertive parental discipline strategies and partially punitive strategies (monitoring and penalty) were associated to more physical and psychological violence by adolescents toward their parents. Finally, implications of these findings for parenting education are discussed.

Positivity construct refers to the propensity to think positively about oneself, life and the future, being closely related to wellbeing and health. Moreover, coping strategies used to manage stress have an important role in the development of mental health problems, one of which is adjustment disorder (AD).

The aim of this study was: Firstly, to analyze the differences in positivity, coping, and some relevant socio-demographic variables between the clinical (formed by patients with AD; N=57) and the control (N=66) groups; and secondly, to analyze whether these variables could predict, using binary logistic regression, the participants’ membership to the clinical or the control group.
The clinical group showed less positivity and a greater use of disengagement strategies compared to the control group. Furthermore, the variables assessed were able to predict the clinical or control group membership with a 91% of success rate. The main risk factors to belong to the clinical group were the use of social support coping and disengagement strategies; whereas active employment status, the use of humor, positivity and younger age decreased this risk.
Consecuencias del abuso sexual infantil: una revisión de las variables intervinientes

Over the last few decade child sexual abuse (CSA) have provoked a great deal of interest, both among the scientific community and the society, due to its prevalence and short and long term consequences. Although most of the studies examining CSA sequelae list numerous psychological, social, behavioral and physical difficulties, certainly not every child abuse survivor shows a significant harm thereafter, existing a great variability on the survivor´s adjustment. In light of this diversity the present work, after review the short and long term consequences of CSA, attempt to discern which are the main variables that determine the effects of the abuse on the survivors. Characteristics of the abuse, survivor and perpetrator, situational factors and, specially, survivor´s cognitive variables have been proved as efficient in order to explain the symptomatology severity. Specifically, studies have found that replacing avoidance coping strategies by approaching ones, eliminating self-blame and family blame attributions and the four traumagenic dynamics feelings, as well as promoting a secure attachment style would have a positive impact in order to prevent future problems caused by the experience of abuse.
