Political Skill in Organizations

Political skill is a construct that was introduced more than two decades ago as a necessary competency to possess to be effective in organizations. Unfortunately, despite appeals by organizational scientists to further develop this construct, it lay dormant until very recently. The present article defines and characterizes the construct domain of political skill and embeds it in a cognition—affect—behavior, multilevel, meta-theoretical framework that proposes how political skill operates to exercise effects on both self and others in organizations. Implications of this conceptualization are discussed, as are directions for future research and practical implications.
Children’s perceptions of exercise ‐ are children mini‐adults?

Pre‐adolescent children (51 girls, 23 boys) communicated their thoughts about leisure‐time physical activity within their own frame of reference. The question, “Is there anything you would like to write or draw about exercise? ” was used to elicit children’s perceptions of “things that make you feel a bit out of breath, hot and sweaty”. Responses were coded for the presence of motivational factors and barriers to exercise participation. Results suggest boys and girls may hold different motivational constructions of physical activity. Motivational barriers, namely lack of energy and enjoyment were mentioned by boys and girls, suggesting negative perceptions of exercise were readily invoked. Discussion of these results considers the similarities with adult views of exercise. Implications for practice concern identification of children holding negative perceptions of physical activity, in order that effective physical activity promotion strategies can be operationalised.
Unruly Places: Urban Governance and the Persistence of Illegality in Hong Kong's Urban Squatter Areas

Our knowledge of the governance of cities has expanded in recent years with the application of Foucauldian approaches. However, the majority of such work has concentrated on areas where governmental control is heightened, such as prisons and asylums. In this article, I discuss unruly places where governments have less control than usual: squatter settlements. Hong Kong has had substantial numbers of squatters throughout its postwar rise from dire poverty to contemporary prosperity. This article draws on documentary analysis and field research from 1982–85 and 1999–2000 to examine changes in the way that the government attempts to regulate these illegally occupied spaces and the ways in which interaction between administrative interventions and the responses of those living there makes the persistence of illegal occupation possible. I argue that three different phases of regulation can be identified: repression, resettlement, and exclusion. While there is considerable continuity in some practices of intervention such as toleration, the nature and outcomes of such practices vary with the changing context and other features of the regulatory regime, [regulation, squatters, governance, illegality, Hong Kong]
Design and Evaluation of Pattern Reconfigurable Antennas for MIMO Applications

In recent years, reconfigurable antennas have been sought to improve the performance of multiple-input multiple-output (MIMO) wireless communication systems. Their ability to dynamically reconfigure their radiation pattern adds diversity in a manner that is not possible with fixed antennas. This paper investigates the performance benefits provided by pattern reconfigurable receiving antennas with uniform beam steering capability. Their potential performance is first estimated using simulations, and for the first time, the effect of uniform beam steering on MIMO system performance is evaluated in a real indoor channel using two electrically steerable passive array radiator (ESPAR) antennas. Performance comparison is made against a pair of monopole antennas using a hardware bit error rate (BER) test-bed that incorporates statistical spatial averaging in order to assess performance improvements in a more realistic way, and analyze the effect of antenna diversity on the overall system performance. The MIMO-ESPAR system reduces BER with certain pattern combinations and excels in capacity evaluations. The ESPAR antennas improve the spatially averaged channel capacity by as much as 37% at 10 dB transmit SNR, and gain an additional 1 bit/s/Hz in peak capacity at 10 dB receive SNR from diversity gain alone. These improvements make pattern reconfigurable antennas promising options in MIMO-related applications.
A Study on Detecting Patterns in Twitter Intra-topic User and Message Clustering

Timely detection of hidden patterns is the key for the analysis and estimating of driving determinants for mission critical decision making. This study applies Cheong and Lee’s “context-aware” content analysis framework to extract latent properties from Twitter messages (tweets). In addition, we incorporate an unsupervised Self-organizing Feature Map (SOM) as a machine learning-based clustering tool that has not been investigated in the context of opinion mining and sentimental analysis using microblogging. Our experimental results reveal the detection of interesting patterns for topics of interest which are latent and cannot be easily detected from the observed tweets without the aid of machine learning tools.
Precise subtyping for synchronous multiparty sessions

The notion of subtyping has gained an important role both in theoretical and applicative domains: in lambda and concurrent calculi as well as in programming languages. The soundness and the completeness, together referred to as the preciseness of subtyping, can be considered from two different points of view: operational and denotational. The former preciseness has been recently developed with respect to type safety, i.e. the safe replacement of a term of a smaller type when a term of a bigger type is expected. The latter preciseness is based on the denotation of a type which is a mathematical object that describes the meaning of the type in accordance with the denotations of other expressions from the language. The result of this paper is the operational and denotational preciseness of the subtyping for a synchronous multiparty session calculus. The novelty of this paper is the introduction of characteristic global types to prove the operational completeness.
The Vocal Repertoire of Adult and Neonate Giant Otters (Pteronura brasiliensis)

Animals use vocalizations to exchange information about external events, their own physical or motivational state, or about individuality and social affiliation. Infant babbling can enhance the development of the full adult vocal repertoire by providing ample opportunity for practice. Giant otters are very social and frequently vocalizing animals. They live in highly cohesive groups, generally including a reproductive pair and their offspring born in different years. This basic social structure may vary in the degree of relatedness of the group members. Individuals engage in shared group activities and different social roles and thus, the social organization of giant otters provides a basis for complex and long-term individual relationships. We recorded and analysed the vocalizations of adult and neonate giant otters from wild and captive groups. We classified the adult vocalizations according to their acoustic structure, and described their main behavioural context. Additionally, we present the first description of vocalizations uttered in babbling bouts of new born giant otters. We expected to find 1) a sophisticated vocal repertoire that would reflect the species’ complex social organisation, 2) that giant otter vocalizations have a clear relationship between signal structure and function, and 3) that the vocal repertoire of new born giant otters would comprise age-specific vocalizations as well as precursors of the adult repertoire. We found a vocal repertoire with 22 distinct vocalization types produced by adults and 11 vocalization types within the babbling bouts of the neonates. A comparison within the otter subfamily suggests a relation between vocal and social complexity, with the giant otters being the socially and vocally most complex species.
Design Principles for Riboswitch Function

Scientific and technological advances that enable the tuning of integrated regulatory components to match network and system requirements are critical to reliably control the function of biological systems. RNA provides a promising building block for the construction of tunable regulatory components based on its rich regulatory capacity and our current understanding of the sequence–function relationship. One prominent example of RNA-based regulatory components is riboswitches, genetic elements that mediate ligand control of gene expression through diverse regulatory mechanisms. While characterization of natural and synthetic riboswitches has revealed that riboswitch function can be modulated through sequence alteration, no quantitative frameworks exist to investigate or guide riboswitch tuning. Here, we combined mathematical modeling and experimental approaches to investigate the relationship between riboswitch function and performance. Model results demonstrated that the competition between reversible and irreversible rate constants dictates performance for different regulatory mechanisms. We also found that practical system restrictions, such as an upper limit on ligand concentration, can significantly alter the requirements for riboswitch performance, necessitating alternative tuning strategies. Previous experimental data for natural and synthetic riboswitches as well as experiments conducted in this work support model predictions. From our results, we developed a set of general design principles for synthetic riboswitches. Our results also provide a foundation from which to investigate how natural riboswitches are tuned to meet systems-level regulatory demands.
Simulation of real time tracking system using RFID technology to enhance quality activities in flexible manufacturing system

Flexible Manufacturing System (FMS) attracts industries to adopt it for its high productivity and flexibility. Recent improvement of FMS focuses on real-time tracking to ease planning, control and inspection to final product. One of the potential tools to be used in tracking, monitoring and controlling the final products is the Radio Frequency Identification (RFID) technology. Implementing RFID will lead to lower cost and high efficiency. This paper simulated a real-time tracking system using RFID technology to enhance and track the quality and inspection activities in FMS using Colored Petri Net (CPN) method. The proposed system suggests using RFID tags on base that carries the parts to be processed in the manufacturing system rather than putting the tag in the parts themselves. RFID Read/writes capability have been assumed in the model. Therefore, updating the data during the process will be adapted, such as reference number and updated status of part in further stages in the system. This gives a chance to use the base with tag again after accomplishing all required operations in the production system for other parts. Thus, this method helps to reduce the required cost for manufacturing. The simulation of the system using CPN tool shows that parts can be tracked successfully and provides more enhancements for production.
Spatiality and the place of the material in schools

Abstract Drawing on a research study into the spatiality of teachers' workplaces, this article explores the ‘concrete realities’ of the artefact-filled world with which teachers, support staff and students interact, and considers the way in which networks of people and things order the spaces of the school. Spatiality is examined explicitly in terms of the relationship between different kinds of space and place, including the network space of relations and objects. In focusing on the relationship between the social and the material, and their implication in the construction of the everyday interactions that constitute the school, the article explores the utility of Actor Network Theories (ANT) as a means of reconciling the two without privileging one over the other or relegating objects to simple cultural or symbolic artefacts. A further challenge is to explore the spatialising force of objects as implicated in the active construction of social space, without resorting to simplistic behavioural determinism. The theoretical focus relates to the empirical concern: how particular spatial arrangements encourage or constrain ways of working together.
The development and validation of a self-report measure of self-actualization

A self-report measure of actualization of potential (MAP) was developed as an alternative to the Personal Orientation Inventory (POI) for assessing successful and functioning individuals. Study 1 describes the item selection carried out by means of a literature review, an international panel of 28 experts and two focus groups. In Study 2 construct validity was established with a sample of 414 subjects. A principal components analysis with oblique rotation reduced the initial item pool to 27, yielding a 5-factor solution. A second-order factor analysis revealed two major components, "self-reference" and "openness to experience". Study 3 achieved a full scale Cronbach's alpha to . 90. Overall the new instrument provides both better theoretical and empirical evidence than the POI, and stronger psychometric properties.
Exploring the Potential of Mobile Crowdsourcing in the Sharing of Information on Items Prices

This article presents the result of a survey performed to identify the potential of using mobile crowdsourcing as means to exchange information on the prices of household items at local stores from the consumers point of view. The potential was identified from four perspectives; mobile devices capability, internet usage pattern, supporting infrastructure and readiness towards information sharing. Survey questionnaires comprising 18 quantitative questions were distributed to 138 respondents in the forms of hardcopy and online softcopy over a one month period in May 2014. Collected data were analysed using descriptive statistics and correlation analysis methods. Findings from the analyses showed that the potential of using mobile crowdsourcing in sharing information of item prices is high as seen from the perspectives of the mobile devices capability and supporting infrastructure. Internet usage pattern of the consumers as well as their attitude towards information sharing are also in support of the potential. To the best of our knowledge, this is the first study that gathered statistical data on the potential of using mobile crowdsourcing for the sharing of information on items prices. Potential is usually assumed based on informal observation on the prevalent of mobile devices and their widespread use, and are not supported by empirical data. It is of value to the broader research communities who are currently engaged in mobile crowdsourcing research for consumers benefits.
COORDINATION DIAGNOSTIC ALGORITHMS FOR TEAMS OF SITUATED AGENTS: SCALING UP

Agents in a team should be in agreement. Unfortunately, they may come to disagree due to sensor uncertainty, intermittent communication failures, etc. Once a disagreement occurs, the agents should detect and diagnose the disagreement. Current diagnostic techniques do not scale well with the number of agents, as they have high communication and computation complexity. We present novel techniques that enable scalability in three ways. First, we use communications early in the diagnostic process to stave off unneeded reasoning, which ultimately leads to unneeded communications. Second, we use light‐weight (and inaccurate) behavior recognition to focus the diagnostic reasoning on beliefs of agents that might be in conflict. Finally, we propose diagnosing only to a limited number of representative agents (instead of all the agents). We examine these techniques in large‐scale teams of situated agents in two domains and show that combining the techniques produces a diagnostic process that is highly scalable in both communication and computation.
Invasive Multiple Sinusitis by Aspergillus Fumigatus in a Patient with AIDS

Infections with various fungi frequently complicate the course of the human immunodeficiency virus infection. Although susceptibility to fungal infections is characteristic of defects in T lymphocyte function, normal phagocytic function is important in host defence against Aspergillus species . This infection is unusual in HIV-positive patients who have major functional defects of T cells with less marked abnormalities of neutrophils or macrophages. There have been reports of invasive pulmonary, cerebral, renal, cardiac, hepatic, cutaneous, mediastinal lymph nodes and medullary aspergillosis in AIDS patients-", We report a rare case of invasive multiple sinusitis by Aspergillus fumigatus in a patient with AIDS.

Interacting with Wall-Size Screens

When attempting to transf er the main interaction paradigms involving mouse, pen, and touch from the desktop to large screens many of them "break". The sheer size of wall-size displays caused users to lose track of the mouse pointer. When using touch or pen input, the screen size makes it hard to reach distant screen content. And those techniques that seem to transfer, now often suffer from limited accuracy, caused by the inferior tracking that many of the large displays offer. I am descr ibing a series of research projects that address these problems.
Improving group processes in transdisciplinary case studies for sustainability learning

Purpose – Deficient group processes such as conformity pressure can lead to inadequate group decisions with negative social, economic, or environmental consequences. The study aims to investigate how a group technique (called INFO) improves students' handling of conformity pressure and their collective judgments in the context of a transdisciplinary case study (TCS) for sustainability learning.Design/methodology/approach – The improvement of normative functioning and output (INFO) group technique was tested in a field experiment embedded in a TCS. The INFO technique involves individual and group assessments of task difficulty. The experiment compares the performance of student groups assigned to control and experimental conditions in estimation tasks related to environmental planning and rail traffic.Findings – The INFO interventions significantly improved the accuracy of group estimates compared to the control conditions. Applying the group technique could promote student's learning and facilitate the se.
Evidence for the involvement of the Arabidopsis SEC24A in male transmission

Eukaryotic cells use COPII-coated carriers for endoplasmic reticulum (ER)-to-Golgi protein transport. Selective cargo capture into ER-derived carriers is largely driven by the SEC24 component of the COPII coat. The Arabidopsis genome encodes three AtSEC24 genes with overlapping expression profiles but it is yet to be established whether the AtSEC24 proteins have overlapping roles in plant growth and development. Taking advantage of Arabidopsis thaliana as a model plant system for studying gene function in vivo, through reciprocal crosses, pollen characterization, and complementation tests, evidence is provided for a role for AtSEC24A in the male gametophyte. It is established that an AtSEC24A loss-of-function mutation is tolerated in the female gametophyte but that it causes defects in pollen leading to failure of male transmission of the AtSEC24A mutation. These data provide a characterization of plant SEC24 family in planta showing incompletely overlapping functions of the AtSEC24 isoforms. The results also attribute a novel role to SEC24 proteins in a multicellular model system, specifically in male fertility.
Transplacental Exposure to AZT Induces Adverse Neurochemical and Behavioral Effects in a Mouse Model: Protection by L-Acetylcarnitine

Maternal-fetal HIV-1 transmission can be prevented by administration of AZT, alone or in combination with other antiretroviral drugs to pregnant HIV-1-infected women and their newborns. In spite of the benefits deriving from this life-saving prophylactic therapy, there is still considerable uncertainty on the potential long-term adverse effects of antiretroviral drugs on exposed children. Clinical and experimental studies have consistently shown the occurrence of mitochondrial dysfunction and increased oxidative stress following prenatal treatment with antiretroviral drugs, and clinical evidence suggests that the developing brain is one of the targets of the toxic action of these compounds possibly resulting in behavioral problems. We intended to verify the effects on brain and behavior of mice exposed during gestation to AZT, the backbone of antiretroviral therapy during human pregnancy. We hypothesized that glutamate, a neurotransmitter involved in excitotoxicity and behavioral plasticity, could be one of the major actors in AZT-induced neurochemical and behavioral alterations. We also assessed the antioxidant and neuroprotective effect of L-acetylcarnitine, a compound that improves mitochondrial function and is successfully used to treat antiretroviral-induced polyneuropathy in HIV-1 patients. We found that transplacental exposure to AZT given per os to pregnant mice from day 10 of pregnancy to delivery impaired in the adult offspring spatial learning and memory, enhanced corticosterone release in response to acute stress, increased brain oxidative stress also at birth and markedly reduced expression of mGluR1 and mGluR5 subtypes and GluR1 subunit of AMPA receptors in the hippocampus. Notably, administration during the entire pregnancy of L-acetylcarnitine was effective in preventing/ameliorating the neurochemical, neuroendocrine and behavioral adverse effects induced by AZT in the offspring. The present preclinical findings provide a mechanistic hypothesis for the neurobehavioral effects of AZT and strongly suggest that preventive administration of L-acetylcarnitine might be effective in reducing the neurological side-effects of antiretroviral therapy in fetus/newborn.
Cowboys, Outlaws and Artists

Advertising’s contribution to the deterioration of meaning in consumer culture has been well established, yet advertising also offers a therapeutic resource to audiences. Early advertisers humanized the modern marketplace with nostalgic appeals to home, hearth and village, yet, against the rising tide of 1960s identity politics, designers made increasing appeals to authenticity. By the 21st century, the modern heroes of authentic individuality - the cowboy, the genius artist, the outlaw - had been fully parodied and debunked, yet an interpretive study of two totemic youth commodities, jeans and sneakers, suggests that the underlying values of freedom, autonomy and individuality are not. Contemporary jeans advertisers rewrite the quest for authenticity within contemporary promotional culture, yet this appeal is not universal.Athletic shoe brands achieved popularity by reflecting the ideology of athleticism rooted in the modernist ethos celebrating achievement, deferral of gratification, discipline and teamwork. The research suggests autonomy and self-authentication are taken most seriously by those most immersed in the quest for anti-modern identity. Even if the marketplace is not a site of absolute personal freedom, to the degree it quells anxieties that the quest for freedom is disappearing in a hyper- commercialized market culture, it may prove therapeutic.
