Industrial and Organizational (I/O) Psychology: The Roles and Purposes of I/O Practitioners in Global Businesses

An Industrial and Organizational (I/O) psychologist is commonly referred to as an I/O practitioner and as an I/O consultant. I/O psychology is the branch of psychology concerned with the application of psychological principles in the workplace. To practitioners, I/O psychology is the application or extension of psychological methods and principles to the solution of organizational and workplace problems, both in the domestic and international arenas. Most commonly, I/O psychology is concerned with those problems caused by human performance and those which affect human performance within organizational contexts. As such, I/O psychologists employ psychological measurement and research findings related to human abilities, motivation, perception, and learning in seeking to improve the fit between the needs of the work organization and those of the people who populate it. Thus, an I/O psychologist plays a paramount role in successful global ventures by addressing two key factors—culture and behavior—resulting in positive return-on-investment (ROI).
MODEL SELECTION FOR SOCIAL NETWORKS USING GRAPHLETS TECHNICAL REPORT

Several network models have been proposed to explain the link structure observed in online social networks. Such models are usually justified by showing that they can replicate certain observed features of real networks, such as a power law degree distribution, a high degree of clustering, and the small world property. This paper addresses the problem of choosing the model that best fits a given real world network. We implement a model selection method based on un-supervised learning. An alternating decision tree is trained using synthetic graphs generated according to each of the models under consideration. Graphs are represented as feature vectors incorporating the frequency counts of all connected subgraphs on 3 and 4 vertices as well as features describing the degree distribution and small world property. We show that the subgraph counts alone are sufficient in separating the training data. For the test data, we take four Facebook graphs from various American Universities. Our results show that models incorporating some form of the preferential attachment mechanism tend to perform the best.
Synaptic Pruning Mechanisms in Learning

1 –Independent Work Report, Spring 2015– Synaptic Pruning Mechanisms in Learning Abstract Synaptic pruning is the process of removing synapses in neural networks and has been considered to be a method of learning. During the developmental stages of the brain, synaptic pruning helps regulate efficiency and energy conservation. However, a destructive algorithm seems to be counter-intuitive to “learning. ” When applied to association networks, pruning networks show evidence of learning associations when given good input. However, the pruning algorithm can be detrimental to network size and even limit learning for networks that are too small or have too high of a frequency threshold. For small networks, implementing constructive algorithm in addition to the pruning one may help ensure that a network continues to grow and learn.
Low-cost, CMOS compatible, Ta2O5-based hemi-memristor for neuromorphic circuits

In the past, tantalum oxide devices have been used to create non-volatile digital memories, whilst neglecting the analogue memristive characteristics of such devices. In this Letter, it is shown that these devices can provide a low-cost, low-power solution for hemi-memristive devices, when used in their pre-formed, memristive region, whilst being fully CMOS compatible. Furthermore, measurements are presented from the devices that have been fabricated and it is shown that these devices do not require electroforming. Electroforming circuitry takes up valuable chip space at the transistor layers and significantly increases fabrication cost, since voltages as high as 12 V are required, which in turn requires extra masks to form high voltage devices and distribution circuits.
ESTRUTURA DE PRÁTICA E PROCESSO ADAPTATIVO NA AQUISIÇÃO DO ARREMESSO DE DARDO DE SALÃO

A aquisicao de habilidades motoras em diferentes estruturas de pratica foi investigada com base em um modelo de nao-equilibrio de aprendizagem motora. Investigou-se, especificamente, os efeitos das praticas variada e constante no processo adaptativo na aprendizagem do arremesso de dardo de salao. Participaram do estudo trinta e nove criancas de ambos os sexos, distribuidas em quatro grupos de acordo com a situacao experimental: pratica constante, pratica aleatoria, pratica constante-aleatoria, e pratica aleatoria-constante. O experimento foi realizado em duas fases (estabilizacao e adaptacao), e envolveu dois tipos de arremesso (com empunhadura comum e com empunhadura profissional). A distância do local de arremesso ao alvo foi manipulada durante a fase de estabilizacao (2,00; 2,60; e 3,20 metros). Os resultados, analisados em termos da media e do desvio padrao de escores, mostraram efeitos semelhantes para todos os grupos em ambas as fases experimentais. As explicacoes para esses resultados envolvem as variacoes na tarefa e sua complexidade, e as instrucoes referentes ao padrao de movimento a ser alcancado.
Isotypic faithful 2-representations of J -simple ﬁat 2-categories

We introduce the class of isotypic 2-representations for ﬁnitary 2-categories and the notion of inﬂation of 2-representations. Under some natural assumptions we show that isotypic 2-representations are equivalent to inﬂations of cell 2-representations.
The Use of Competencies and Workforce Diversity: Are They at Cross Purposes?

Organizations are continuously seeking improved ways of selecting the ‘best’ people for a particular job or organization, which can be challenging in the face of an increasingly diverse workforce (Ensher, Grant-Vallone & Donaldson, 2001). Particularly in Canada, this activity has become a very complex task, as firms must ensure that all individuals are given fair and equitable treatment, especially concerning the functions of selection, training, and performance appraisal. With the increased number of people from other countries and those who do not come from English, French and British origins entering the Canadian workforce, more emphasis is being placed on non-exclusionary and anti-discriminatory policies and procedures within the realm of diversity management. Two of the most important trends of the past decade are a continuously growing diverse workforce, and increased competition for businesses resulting from the globalization of markets (Jain & Verma, 1996). Developing a “global mindset” has become a key prerequisite for successfully competing and growing in worldwide markets, where diversity is seen as a source of opportunities (Paul, 2000). The interconnections between cultures is resulting in the emergence of cultural mixtures and greater cultural heterogeneity as a result of this globalization (Aponte & Crouch, 1995; Hermans & Kempsen, 1998). The employment of minorities, however, has been one of the most complex organizational and human resource issues over the last 40 years (Jain, Sloane & Horwitz, 2003).
Pharmacological fMRI and EEG for the development of novel analgesic compounds. André MOURAUX. Chargé de recherches

Functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) have been introduced in pharmacological studies with the aim to measure the modulation of brain activity by drugs acting directly on the central nervous system (CNS) or indirectly on its afferent input. By providing novel and specific biomarkers which could substitute or complement clinical endpoints, this approach is thought to have the potential to contribute to the early clinical stages of drug development, and, in particular, to the development of novel analgesic compounds. Here, we shall (1) examine the ability of these methods to investigate the actions of drugs on the CNS, (2) review the studies of analgesic drugs which have already used these techniques, and (3) discuss potential caveats in interpreting modulations of fMRI and EEG activity as reflective of drug-induced changes in neuronal activity.
Specializing the operation of an explicit rule

When dealing with a newly learned rule, one is often aware of relying on previous episodes of applying the rule. The specific materials or problems to which the rule was originally applied seem to have some privilege, particularly when the rule initially seems quite abstract. Understanding a difficult rule, or at least understanding how to apply it, seems to occur in terms of previous concrete applications. This impression is corroborated by Ross in his interesting work on remindings in problem solving (Ross, 1984, 1987, 1989; Ross & Kennedy, 1990). He demonstrated that performance while learning a word processing program or learning to solve simple probability problems is influenced by specific analogies with previously encountered problems. But what happens to these prior episodes of problem solving when the rule is not difficult, or when one has had sufficient practice to make it no longer seem difficult? Introspectively, the prior examples seem to disappear from active processing, a suggestion reflected in a wide variety of theories in cognitive psychology. In this article we argue that under common conditions, prior episodes retain an important role in helping apply the rule to new material, well after clear awareness of the prior episodes has disappeared. We make an ecological argument for the conditions under which episode-based knowledge has continued value.
IRREDUCIBLE QUADRANGULATIONS OF THE KLEIN BOTTLE

In this paper, we shall determine the complete list of irreducible quadrangulations of the Klein bottle. By this result, we can easily list all the minorminimal 2-representative graphs on the Klein bottle. Moreover, we shall show that any two bipartite quadrangulations of the Klein bottle with at least 10 vertices are transformed into each other by a sequence of diagonal slides and a sequence of diagonal rotations, up to homeomorphism, if they have the same number of vertices.
EPITHELIAL-MESENCHYMAL INTERACTIONS DURING ODONTOGENESIS

Recently we reported ultrastructural observatlons which indicated that matrix vesicles were actual constituents of the intercellular organic matrix during embryonic tooth development (14). It is assumed that many of these matrix vesicles are involved in formative aspects of dentinogenesis or amelogenesis, two primary extracellular processes that occur during embryonic tooth formation The fractionation of matrix vesicles from carfilage by means of demineralization followed by collagenase dtgestion of the organic matrix and subsequent differential centrlfugation has been reported (1) and recently reviewed with respect
Equivariant Schrödinger maps in two spatial dimensions: The $\mathbb{H}^{2}$ target

EQUIVARIANT SCHR ODINGER MAPS IN TWO SPATIAL DIMENSIONS: THE H 2 TARGET arXiv:1212.2566v1 [math.AP] 11 Dec 2012 I. BEJENARU, A. IONESCU, C. KENIG, AND D. TATARU Abstract. We consider equivariant solutions for the Schr¨odinger map problem from R 2+1 to H 2 with finite energy and show that they are global in time and scatter. 1. Introduction The Schr¨odinger map equation in R 2+1 with values into S µ ⊂ R 3 is given by u t = u × µ ∆u, u(0) = u 0 where µ = ±1, the connected Riemannian manifolds S µ , S 1 = S 2 = {y = (y 0 , y 1 , y 2 ) ∈ R 3 : y 1 2 + y 2 2 + y 3 2 = 1}; S −1 = H 2 = {y = (y 0 , y 1 , y 2 ) ∈ R 3 : −y 1 2 − y 2 2 + y 3 2 = 1, y 3 > 0}, with the Riemannian structures induced by the Euclidean metric g 1 = dy 0 2 + dy 1 2 + dy 2 2 on S 1 , respectively the Minkowski metric g −1 = −dy 0 2 + dy 1 2 + dy 2 2 on S −1 . Thus S 1 is the 2-dimensional sphere S 2 , while S −1 is the 2-dimensional hyperbolic space H 2 . With η µ = diag(1, 1, µ), the cross product × µ is defined by v × µ w := η µ · (v × w). This equation admits a conserved energy, Z E(u) = |∇u| 2 µ dx 2 R 2 and is invariant with respect to the dimensionless scaling u(t, x) → u(λ 2 t, λx). The energy is invariant with respect to the above scaling, therefore the Schr¨odinger map equation in R 2+1 is energy critical. The local theory for classical data was established in [25] and [21]. We recall Theorem 1.1 (McGahagan). If u 0 ∈ H ˙ 1 ∩ H ˙ 3 then there exists a time T > 0, such that (1.1) has a unique solution in L ∞ t ([0, T ] : H ∩ H ). The local and global in time of the Schr¨odinger map problem with small data has been intensely studied for the case µ = 1 corresponding to S 2 as target, see [3], [4], [5], [6], [9], [15], [16]. The state of the art result for the problem with small data was established by the authors in [6] where they proved that classical solutions (and in fact rough solutions too) with small energy are global in time. These results are expected to extend to the case µ = −1, corresponding to H 2 as a target. I.B. was supported in part by NSF grant DMS-1001676. A.

COUNTRYSIDE BIOGEOGRAPHY: USE OF HUMAN-DOMINATED HABITATS BY THE AVIFAUNA OF SOUTHERN COSTA RICA

Understanding the multifaceted relationship between biodiversity and land- use intensity is key to conservation policy. To begin to characterize this relationship in a tropical region, we investigated the bird fauna in an agricultural landscape in southern Costa Rica. Landsat Thematic Mapper (TM) data show that about 27% of the land remains forested in the 15 km radius study region encompassing our sites. The rest was cleared about 40 yr ago for relatively small-scale coffee and cattle production, intermixed with other crops. Our goals were to: (1) compare the composition of the avifauna found in forest- fragment and open habitats of the countryside; (2) assess the faunal change that has occurred since deforestation; and (3) provide a baseline for future comparisons. We surveyed the avifauna of eight forest fragments (0.3-25 ha) and 13 open-habitat sites (1.0 ha each) in the agricultural landscape. The pre-deforestation avifauna was ap- proximated by the long-term bird list for the largest forest fragment (Las Cruces, LC; 227 ha) in the study region. We assumed conservatively that a species recorded in LC but not detected elsewhere occurred only in LC. Of the 272 locally extant bird species considered in this study, 149 (55%) occurred in forest habitats only. There was a significant positive correlation between forest fragment size and species richness for these forest birds. Of the remaining 123 species, 60 (22% of the total) occurred both in forest and open habitats. Sixty-three species (23%) occurred in open habitats only; the three nonnative species (1%) are in this group. Based on comparisons with larger forest tracts outside of the study region, it appeared that between 4 and 28 species (1-9% of the possible original totals) have gone locally extinct since deforestation began. The avifauna of open habitats was similar through- out the study region and did not vary with proximity to extensive forest. A substantial proportion of the native bird fauna occurs in a densely (human) populated, agricultural landscape almost a half-century after extensive clearance. There are, however, cautionary messages: (1) the common occurrence of forest birds in human-dominated coun- tryside (including both forest-fragment and open habitats) does not necessarily imply that these species maintain sustainable populations there; (2) about half of the species have little prospect of surviving outside of the forest; and (3) ongoing intensification of land use may greatly reduce avian diversity in countryside habitats. Nonetheless, countryside habitats may buy time for the conservation of some species; at best, they may even sustain a moderate fraction of the native biota.
THERAPIE GENIQUE ET ANGIOGENESE THERAPEUTIQUE

ans une situation d’ischémie sévère, l’un des moyens d’adaptation de l’organisme est le développement d’une circulation collatérale de suppléance (1). Au niveau du myocarde par exemple, le développement d’une telle circulation peut minimiser les conséquences de l’occlusion d’un gros tronc épicardique. Dans certains cas rares, l’existence de ce type de circulation peut même entraîner une “revascularisation” complète du territoire qui dépend du ou des vaisseau(x) occlus. Cependant, cette circulation collatérale, bien connue des cliniciens, est le plus souvent insuffisamment développée pour assurer une vascularisation satisfaisante du tissu à risque.
Metric Lie 3-algebras in Bagger-Lambert theory

We recast physical properties of the Bagger-Lambert theory, such as shift-symmetry and decoupling of ghosts, the absence of scale and parity invariance, in Lie 3-algebraic terms, thus motivating the study of metric Lie 3-algebras and their Lie algebras of derivations. We prove a structure theorem for metric Lie 3-algebras in arbitrary signature showing that they can be constructed out of the simple and one-dimensional Lie 3-algebras iterating two constructions: orthogonal direct sum and a new construction called a double extension, by analogy with the similar construction for Lie algebras. We classify metric Lie 3-algebras of signature (2,p) and study their Lie algebras of derivations, including those which preserve the conformal class of the inner product. We revisit the 3-algebraic criteria spelt out at the start of the paper and select those algebras with signature (2,p) which satisfy them, as well as indicate the construction of more general metric Lie 3-algebras satisfying the ghost-decoupling criterion.
Langfristige Ursprünge und dauerhafte Auswirkungen. Zur historischen Einordnung der siebziger Jahre

Wohl keines der Jahrzehnte nach dem Ende des Zweiten Weltkriegs war derart stark von widerstreitenden Entwicklungen gekennzeichnet wie die siebziger Jahre. Sprach man nach dem Krieg in Deutschland von Stunde Null und Neubeginn, in den funfziger Jahren dann von Wiederaufbau, in den Sechzigern von Reform und Emanzipation, so loste sich im Verlauf der siebziger Jahre die scheinbare Eindeutigkeit der Zuordnungen auf. Politikwissenschaftler und Historiker nahmen alsbald Zuflucht zum inhaltsleeren Begriff der Krise, als hatte es Krisen zuvor nicht gegeben und als sei man in der Lage, exakt bestimmen zu konnen, was eine »Krise« denn konkret ausmache.
Studies on Phthalimide Derivatives as HIV-1 Reverse Transcriptase Inhibitors

The novel non-nucleoside HIV-1 reverse transcriptase inhibitors in a phthalimide series were subjected to the three-dimensional quantitative structure-activity relationship (3D QSAR) studies using comparative molecular field analysis (CoMFA) and comparative molecular similarity indices analysis (CoMSIA). The best predictive CoMFA model gave cross-validated r (q) = 0.688, non-cross-validated r = 0.996, included the highest occupied molecular orbital (HOMO) energies in addition to CoMFA fields, and the best predictive CoMSIA model has q = 0.629, non-cross-validated r = 0.994, included steric, electrostatic, hydrophobic and hydrogen bond acceptor fields. A test set of 12 compounds was used to determine the predictive value of the models. The calculated (predicted) and experimental inhibitory activities were well correlated. The analysis of the 3D contour maps from both CoMFA and CoMSIA models offer important structural insight into designing novel and more active compounds prior to their synthesis.
بررسی پیوستگی پیاپی بودن پلی AT ژن XPC در بیماران دچار بدخیمی پستان

Introduction: Breast cancer is a malignant proliferation of epithelial cells that cover the breast ducts or lobes. The accumulation of DNA damage is considered as a major factor in breast cancer. One of the most important defense mechanisms is Nucleotide Excision Repair (NER). Dysregulation of DNA repair genes expression is important for breast carcinogenesis. XPC(Xeroderma pigmentosum, complementation group C) is an important NER gene that recognizes the damage caused by a variety of bulky DNA adducts. Poly AT (PAT) sequence is one of important polymorphisms in this gene. Objective: This study investigated the relationship of the XPC PAT polymorphism with breast cancer. Materials and Methods: In this Case-Control study, we analyzed 79 patients and 120 healthy controls. The genotyping of PAT polymorphism was performed using polymerase chain reaction (PCR) and statistical analyses were conducted by theMedCalc statistical software (version 12.1). Results: Among cancer cases, the distributions of PAT-/-, PAT-/+ and PAT+/+ genotypes were 66%, 10%, and 24%, respectively. Among controls, the distributions of PAT-/-, PAT-/+ and PAT+/+ genotypes were 71%, 19%, 10%, respectively. The genotype frequencies did differ significantly between patients and controls (P=0.01). The frequency of PAT+ allele was significantly higher in patients (0.30) than in the controls (0.20), (P=0.02). Conclusion: Our study suggests that XPC Poly AT sequence polymorphism might be a genetic predisposing factor for breast Cancer. However, larger population-based studies are needed for clarifying the role of XPC gene polymorphism in breast Cancer. Conflict of interest: none declared
THE LEAST QUADRATIC NON-RESIDUE, VALUES OF L-FUNCTIONS AT s = 1, AND RELATED PROBLEMS

In this paper, we study explicit and theoretical bounds for several interesting quantities in number theory, conditionally on the Generalized Riemann Hypothesis. Specically, we improve the existing explicit bounds for the least quadratic non-residue and the least prime in an arithmetic progression. We also rene the classical conditional bounds of Littlewood for L-functions at s = 1. In particular, we derive explicit upper and lower bounds for L(1; ) and (1+it), and deduce explicit bounds for the class number of imaginary quadratic elds. Finally, we improve the best known theoretical bounds for the least quadratic non-residue, and more generally, the least k-th power non-residue. In this paper, we establish bounds for several important quantities in analytic number theory conditionally on the Generalized Riemann Hypothesis (GRH). We will bound the least quadratic non-residue (and more generally the least k-th power non-residue), the least prime in an arithmetic progression, the values of L-functions at s = 1 and the class number of imaginary quadratic elds. Our method relies on choices of test functions in variants of the explicit formula. As we have only paltry information on the vertical distribution of zeros of L-functions, any cancelation in the sum over zeros is ignored. It is natural to wonder what the optimal bounds may be in this framework. 1.1. The least quadratic non-residue. There are many number theoretic algo- rithms which depend on GRH. A good example is that of the primality testing algorithm of Miller (15), the main step of which depends on the existence of a small quadratic non-residue. Fix a positive integer q > 2, and letN (q) denote the small- est quadratic non-residue modulo q. Then the boundN (q) = O(log 2 q) proven by Ankeny (1) conditionally on GRH enabled Miller to prove that his algorithm runs in O(log 4 q log logq) time. In this and similar applications, it is useful when implementing the algorithm to have a more explicit bound forN (q), and this was the motivation behind the work of Bach (2) and Bach and Sorenson (5). To be precise, Bach showed that
