Validation of the face-name pairs task in major depression: impaired recall but not recognition

Major depression can be associated with neurocognitive deficits which are believed in part to be related to medial temporal lobe pathology. The purpose of this study was to investigate this impairment using a hippocampal-dependent neuropsychological task. The face-name pairs task was used to assess associative memory functioning in 19 patients with major depression. When compared to age-sex-and-education matched controls, patients with depression showed impaired learning, delayed cued-recall, and delayed free-recall. However, they also showed preserved recognition of the verbal and nonverbal components of this task. Results indicate that the face-name pairs task is sensitive to neurocognitive deficits in major depression.
Cooperative Localization for Mobile Networks: A Distributed Belief Propagation–Mean Field Message Passing Algorithm

We propose a hybrid message passing method for distributed cooperative localization and tracking of mobile agents. Belief propagation and mean field message passing are employed for, respectively, the motion-related and measurement-related parts of the factor graph. Using a Gaussian belief approximation, only three real values per message passing iteration have to be broadcast to neighboring agents. Despite these very low communication requirements, the estimation accuracy can be comparable to that of particle-based belief propagation.
Expatriation as a Maturation Opportunity: A Psychoanalytical Approach Based on ‘Copy and Paste’

In order to understand the success of an expatriation, the traditional approach generally focuses on theoretical models of the expatriate’s adjustment. The psychoanalytical approach seems more powerful in that it sheds light on the significant changes in the individual’s perception of himself and of his environment brought about by the experience of expatriation. In the psychoanalytical approach developed in this article, expatriation may be seen as a maturation opportunity for the individual. The concept of transitional space helps us to understand how people move from ‘copy and cut’ to ‘copy and paste’. Moving from copy to paste is a necessary stage to achieve autonomy. Using the psychoanalytical approach throws light on and reinforces the discoveries presented in the traditional approach literature. An empirical study allows us to confront our theoretical approach to individuals’ factual experiences of expatriation. Implications for both organizations and individuals are presented, in particular, the scope of their responsibilities regarding the expatriation decision.
Black Women in the Ivory Tower, 1850–1954: An Intellectual History by Stephanie Y. Evans

Edited by Layli D. Phillips NewYork: Routledge (2006) ISBN10: 0415954118. 437 pp., Cloth, $100.00; Paper, $39.95 Every year, the National Urban League (NUL) issues a compendium of essays, facts, and statistics that make up its signature report, ‘‘The State of Black America. ’’ For the report, popular among journalists, grant writers, and policy wonks, the editors choose an annual theme and invite influential scholars and popular public officials to write essays to help contextualize and interpret the dry and rather abstruse graphs, charts, and figures documenting home ownership, workforce participation, infant mortality, educational attainment. The wide range of indexes form a matrix used to determine its mega-index—the NUL’s trademarked ‘‘Equality Index. ’’ This index of indexes reduces the entire state of Black America to a raw number, where ‘‘an index number of less than one means that blacks are doing relatively worse than whites,’’ and for 2007, that number was 0.73 (NUL, State of Black America 2007:17). The report is arbitrary, essentialist, homogenizing, and explicitly reductionist, but it’s a sincere and informative way to document change over time and remind all Americans that racism exists and discrimination persists. For 2007, the theme was ‘‘Portrait of the Black Male,’’ and Barack Obama wrote the foreword and recounted some of the high points of the year, but focused on the continued vulnerability of Black people in general and Black men in
Mobile Application Installation Influences: Have Mobile Device Users Become Desensitized to Excessive Permission Requests?

The purpose of this study was to investigate constructs that influence consumers before deciding to download and install mobile device applications. These constructs include market trust, risk perceptions, privacy concerns, and precautions. Through a survey, a prediction model was created that attempts to predict whether respondents would download applications asking for excessive permissions. The model results indicate those that take more precautions are less likely to download apps requesting excessive permissions. But the precautions taken by participants may be inadequate and may leave consumers with a false since of security. Another key finding is that some consumers may have become desensitized to excessive permissions. These consumers knowingly install apps requesting excessive permissions for reasons such as nothing bad has happened to them before or the app usually has a good reason for requesting questionable permissions. The security implications of permission desensitization and inadequate precautions are discussed.
A hybrid Sentiment Classification method using Neural Network and Fuzzy Logic

Neural Network(NN) and fuzzy systems are suitable for determining the input-output relationships. NN contend with numeric and quantitative information whereas fuzzy systems can handle symbolic and qualitative information. Coupling of Neural Network and Fuzzy Logic results in an intelligent crossbreed system widely referred to as Neuro-fuzzy system (NFS) that exploits the most effective qualities of these two approaches expeditiously. The coupled system combines the human alike logical reasoning of fuzzy systems with the training and connectedness structure of neural network. In this paper, we propose a method for performing Sentiment Classification using an NN and fuzzy set theory. In this method input reviews are fuzzified by using Gaussian membership function and fuzzification matrix is build. This matrix is transposed and passed to Multilayer Perceptron Backpropagation Network(MLPBPN).
Low False-Positives in an mLumin-Based Bimolecular Fluorescence Complementation System with a Bicistronic Expression Vector

The simplicity and sensitivity of the bimolecular fluorescence complementation (BiFC) assay make it a powerful tool to investigate protein-protein interactions (PPIs) in living cells. However, non-specific association of the fluorescent protein fragments in a BiFC system can complicate evaluation of PPIs. Here, we introduced a bicistronic expression vector, pBudCE4.1, into an mLumin-based BiFC system, denoted as the BEVL-BiFC system. The BEVL-BiFC system achieved a 25-fold contrast in BiFC efficiency between positive (Fos/Jun) and negative (ΔFos/Jun) PPIs. The high BiFC efficiency was due to a low false-positive rate, where less than 2% of cells displayed BiFC in the negative control. K-Ras and its interactive proteins, Ras binding domain (RBD) of Raf-1 and Grb2 were used to confirm the accuracy of the BEVL-BiFC system. The results also provide direct evidence in individual cells that post-translational modification of K-Ras and its localization at the plasma membrane (PM) were not essential for the interaction of K-Ras and Raf-1, whereas the interaction of Grb2 and K-Ras did depend on the PM localization of K-Ras. Taken together, the BEVL-BiFC system was developed to reduce the false-positive phenomenon in BiFC assays, resulting in more robust and accurate measurement of PPIs in living cells.

Adaptability and Neural Reuse in Minimally Cognitive Agents

Cognitive agents are continuously faced with new problems. To facilitate adaptation, emerging theories of neural reuse propose that evolution might often favor re-purposing existing brain structures for new functions. This paper presents a novel approach to the study of neural reuse based on the evolution of simulated agents in an object-categorization task. We artificially evolve populations of dynamic neural networks to perform two variants of a categorization task that alternate over evolutionary time. We find that populations become increasingly adaptive over repeated exposures to the tasks. Analysis of evolved networks reveals two types of equally-fit solutions: one that is specialized to a given task variant and does not adapt to changes easily; and another that is more general, in that it can adapt to the other task with minimal change to its structure. Interestingly, we find that populations exposed to alternating tasks spontaneously locate the latter type of structures.
An Exploration of the Effect of Cognitive and Collaborative Strategies on Keyboard Skills of Music Education Students

In the United States, all music education majors at the tertiary level who graduate from institutions accredited by the National Association of Schools of Music must demonstrate piano proficiency. Yet many practicing music educators report that they do not use the piano while teaching due to a lack of perceived competence. Peer collaboration and cognitive strategies have been demonstrated to be effective when learning. Typically, piano skills are taught in group piano laboratories, where collaborative work could be incorporated. This study explored development of sight-reading and harmonization skills among students (N = 12) during the final semester of group piano, by employing cognitive strategies and collaborative learning. In this small study, students engaged in collaborative learning improved test scores. Additionally, they displayed improvement in self-efficacy, problem solving, and deliberate practice and demonstrated persistence in completing piano assignments.
Scalable Run-time Data Indexing and Querying for Scientific Simulations

Scientific simulations running at scale on highend computing systems are generating tremendous amounts of raw data, which has to be carefully analyzed before scientists can derive insights from simulations and better understand the phenomena being modeled. Query-driven data analysis is an important technique used by scientists to gain insights from data, especially to capture intermittent transient information at simulation run-time. However, the increasing data volumes and associated I/O costs (latency and energy) are quickly making it infeasible to perform post-simulation query-driven data analysis in a cost-effective and timely manner. To address this challenge, in this paper, we present a scalable data indexing and querying framework using a data staging approach to support run-time query-driven data analysis for large scale scientific simulations. We achieve scalability, low overheads and minimal impact on the simulations by offloading computationally expensive indexing and querying to data staging servers. We also present an experimental evaluation, which demonstrates the performance and scalability of the framework.
Extending a hybrid tag-based recommender system with personalization

Tagging activity has been recently identified as a potential source of knowledge about personal interests, preferences, goals, and other attributes known from user models. Tags themselves can be therefore used for finding personalized recommendations of items. This paper proposes a semantic extension for a hybrid tag-based recommender system, which suggests similar Web pages based on the similarity of their tags. The semantic extension aims at discovering tag relations which are not considered in basic syntax similarity. With the goal of generating more semantically grounded recommendations, the proposal extends a hybrid tag-based recommender system with a semantic factor, which looks for tag relations in different semantic sources. In order to evaluate the benefits acquired with the semantic extension, we have compared the new findings with results from a previous experiment involving 38 people from 12 countries using data from del.icio. us.
Reduction of switching loss for a transformer-based three-phase grid-connected inverter

A gain-based space vector modulation (G-SVM) method is proposed to reduce switching losses for a transformer-based three-phase grid-connected voltage source inverter. The total power losses are analyzed and divided into two parts. Copper loss and iron loss are named as the uncontrollable losses. Switching losses of IGBTs and Diodes are defined as the controllable losses. The switching loss is decreased by adding a gain component to three-phase reference voltages under space vector pulse width modulation scheme. The method is simple and easily implemented. Simulation and experimental results confirm the feasibility and validity of the method.
Distribution of Type II Diabetes in Nuclear Families

Type II diabetes has a substantial genetic component, but the mode of inheritance and the molecular basis of this inheritance are uncertain. This study documents the familial distribution of the disease in the parents and siblings of a consecutive series of type II diabetic subjects. We studied 66 first-degree relatives of 20 white subjects with type II diabetes and both parents alive. They were tested with a continuous infusion of glucose (5 mg · kg IBW−1 · min−1) (n = 49) or FPG and hemoglobin A1c (n = 17). Seven probands had neither parent affected with diabetes or IGT, 10 had one parent affected (6 with diabetes and 4 with IGT), and 3 had both parents affected. The probands with affected and those with unaffected parents were phenotypically similar. These findings indicate that a sizable subgroup of type II diabetic subjects may have neither parent affected with a demonstrable abnormality of glucose tolerance. The assumption of autosomal dominance with complete penetrance is not supported, although it remains possible that a dominant gene of low penetrance may play a role in some pedigrees. Polygenic inheritance would appear likely, and genetic heterogeneity may occur. The inheritance of diabetic traits from phenotypically normal parents needs to be considered in the analysis of genetic linkage with type II diabetes.
CD 8 a 1 and CD 8 a 2 Subclasses of Dendritic Cells Direct the Development of Distinct T Helper Cells In Vivo

Cells of the dendritic family display some unique properties that confer to them the capacity to sensitize naive T cells in vitro and in vivo. In the mouse, two subclasses of dendritic cells (DCs) have been described that differ by their CD8 a expression and their localization in lymphoid organs. The physiologic function of both cell populations remains obscure. Studies conducted in vitro have suggested that CD8 a 1 DCs could play a role in the regulation of immune responses, whereas conventional CD8 a 2 DCs would be more stimulatory. We report here that both subclasses of DCs efficiently prime antigen-specific T cells in vivo, and direct the development of distinct T helper (Th) populations. Antigen-pulsed CD8 a 1 and CD8 a 2 DCs are separated after overnight culture in recombinant granulocyte/macrophage colony-stimulating factor and injected into the footpads of syngeneic mice. Administration of CD8 a 2 DCs induces a Th2-type response, whereas injection of CD8 a 1 DCs leads to Th1 differentiation. We further show that interleukin 12 plays a critical role in Th1 development by CD8 a 1 DCs. These findings suggest that the nature of the DC that presents the antigen to naive T cells may dictate the class selection of the adaptative immune response.
Facilitating public speaking fear reduction by increasing the salience of disconfirmatory evidence

The primary objective of the current study was to investigate whether adding videotape feedback procedures to exposure treatment would facilitate public speaking fear reduction. Participants meeting DSM-IV criteria for social phobia were randomized to receive non-pill placebo, exposure without videotape feedback, exposure with audience videotape feedback, or exposure with performance videotape feedback. Assessments were conducted at pretreatment, posttreatment, and 1-month follow-up. Having participants contrast actual audience responses to responses they imagined did not facilitate changes in participants’ predictions about the negative consequences of appearing anxious in front of others, nor did it result in greater anxiety reduction compared to exposure alone. On the other hand, having participants contrast their imagined performance to their actual performance accelerated the speed of improvement in public
‘Twenty years mean nothing’

What happened after the New World Information and Communication Order (NWICO) and the report prepared by the MacBride Commission: is it the case, in the words of the popular tango Volverby Carlos Gardel, that 20 years mean nothing? This article analyses the global discussions around the flow of information and communication from the NWICO to the WSIS. The aim of this article is to look at the movements, breaks and continuities which relate not only to the relationship between governments, but also to the main economic, technological, political and social trends in both historical moments. Additionally, the article notes the changes in the agents involved and conceptual shifts in the various stages of the discussion. The article reconstructs the evolution of the proposals aimed at democratizing the communication structures, to enable an analysis of their relevance to the current debate about the ‘Information Society’, a term which, though repeatedly used in recent years, gained momentum in the first phase of the World Summit on the Information Society (WSIS) held in December 2003 in Geneva. Our hypothesis is that the frustration resulting from the NWICO debates at UNESCO in the 1970s is a key motivation for the new players at the WSIS summits in Geneva and Tunis – they do not want to repeat past mistakes. However, we consider that the struggle is still political; it is based on a dispute over economic and symbolic resources. It has become increasingly important to re-state the need to democratize the communicational resources of society.
Shifted-excitation Raman difference spectroscopy for in vitro and in vivo biological samples analysis

The contamination of the Raman scattering signal with luminescence is a well-known problem when dealing with biological media excited by visible light. The viability of the shifted-excitation Raman difference spectroscopy (SERDS) technique for luminescence suppression on Raman spectra of biological samples was studied in this work. A tunable Lithrow-configuration diode laser (λ = 785 and 830 nm) coupled (directly or by optical fiber) to a dispersive Raman spectrometer was employed to study two sets of human tissues (tooth and skin) in order to determine the set of experimental parameters suitable for luminescence rejection. It was concluded that systematic and reproducible spectra of biological interest can be acquired by SERDS.
A Comparison Of Muscular Activation During The Back Squat And Deadlift to the Countermovement Jump

The purpose of this study was to determine whether the back squat (BS) or deadlift (DL) is most similar to the countermovement jump (CMJ) in terms of peak muscular activation. The muscles assessed in this study were the erector spinae (ES), gluteus maximus (GM), biceps femoris (BF), vastus medialis (VM), and gastrocnemius (GN). These five muscles were chosen do to their involvement in all of these exercises. Ten college-aged males (24±1.18yrs) with a minimum of 1 year strength training experience volunteered for this study. Participants must have been strength trained and could BS and DL 1.5 x bodyweight. Results showed that only the peak muscular activation of the GN was significantly different (p<0.05) among all muscles between the BS (3.97mV) and CMJ (8.36mV). There were no significant differences between the DL (6.20mV) and CMJ in muscular activation. However when a Pearson Product Correlation was performed, the CMJ and DL showed a weak correlation among all muscles (ES=0.27, GM=0.42, BF=0.46, VM=0.45, GN=0.24). The CMJ and BS only showed a weak correlation among the ES, BF and GN (0.44, 0.22, and 0.32 respectively) and strong correlation for the GM and VM (r = 0.73, 0.77, respectively). This study suggests that in terms of peak muscular activation, the DL is more similar to the CMJ than the BS since no significant differences were found in muscular activation. However, muscle activation of the VM and GM during the BS was strongly correlated to the CMJ.
Denver’s Citizen/Police Complaint Mediation Program

Ensuring police use their authority justly is a persistent concern. Yet, there is little agreement on the most effective mechanisms for promoting accountability. The present study seeks to contribute to a growing body of research on mediation of police disputes by assessing variation in levels of satisfaction among officers and citizens. Using data collected by the Denver Office of the Independent Monitor, the study assesses the degree to which mediation produced differential levels of satisfaction. The study finds that both police and civilian participants in the mediation program were significantly more satisfied than individuals who participated in traditional complaint processing. In addition, the study finds that mediation is likely to have even stronger effects on satisfaction for Latino complainants, and female police officers. Implications and suggestions for future research are discussed.
Characterization of proteome dynamics during growth in oleate reveals a new peroxisome-targeting receptor

ABSTRACT To optimally perform the diversity of metabolic functions that occur within peroxisomes, cells must dynamically regulate peroxisome size, number and content in response to the cell state and the environment. Except for transcriptional regulation little is known about the mechanisms used to perform this complicated feat. Focusing on the yeast Saccharomyces cerevisiae, we used complementary high-content screens to follow changes in localization of most proteins during growth in oleate. We found extensive changes in cellular architecture and identified several proteins that colocalized with peroxisomes that had not previously been considered peroxisomal proteins. One of the newly identified peroxisomal proteins, Ymr018w, is a protein with an unknown function that is similar to the yeast and human peroxisomal targeting receptor Pex5. We demonstrate that Ymr018w is a new peroxisomal-targeting receptor that targets a subset of matrix proteins to peroxisomes. We, therefore, renamed Ymr018w, Pex9, and suggest that Pex9 is a condition-specific targeting receptor that enables the dynamic rewiring of peroxisomes in response to metabolic needs. Moreover, we suggest that Pex5-like receptors might also exist in vertebrates. Highlighted Article: A high-content screen uncovered many changes in protein localization in yeast grown in oleate and highlighted a new condition-specific peroxisomal protein, Pex9, which targets a subset of proteins to peroxisomes.
