A Study on Trust Dynamics Influencing Knowledge Sharing in Organization

This study explores how group behavior influences knowledge sharing by conducting a process of trust dynamics development. Whether different degrees of trust among team members differ in terms of the operational development of socialization and natural form is also analyzed. An experiment was conducted from the perspective of process of trust dynamics development to understand how group behavior influences knowledge sharing. A questionnaire survey was also performed to evaluate how quantity of knowledge sharing and quality of knowledge are related.Initial trustworthiness and early communication level influence team members in their early trust. Early trust also increases the late cohesiveness and late satisfaction of a team and, simultaneously, affects team knowledge and sharing behavior. Additionally, the communication level between the team members impacts the late cohesiveness and knowledge share quality of a team. Moreover, goal conflict, opportunism and information asymmetry significantly influence the knowledge sharing of team members. Results of this study provide a valuable reference for managers attempting to understand how trust dynamics development influences knowledge sharing among team members.

The purpose of this study were to examine the relationship of anxiety in learning with motivation to learn. The study was descriptive correlational. Results showed that there was no significant relationship between anxiety in learning and motivation to learn. Means that the higher the anxiety study, the higher the students' motivation.
Study on performance of 80 watt floating photovoltaic panel

Photovoltaicpanels are used to generate electric power. The surface temperature of the photovoltaic (PV) panels will affect theirefficiency,where the increment of temperature will decreasetheir efficiency and total power gain. In this study, we will discuss the performance of an 80 W floating photovoltaic (PV) panel in a pond simulator, whereby in a two hour experiment it shows up to 15.5% increment of energy gain compared to a normal photovoltaic (PV) panel. The floating photovoltaic (FPV) panel was designed by replacing the photovoltaic panel frame with a material that has the ability to float on a water surface and is capable of transferring heat at the back of the photovoltaic surface. A heat sink is used to transfer heat at the bottom of the photovoltaic panel, which will decrease the surface temperature when placed on the water surface. The best performance of the photovoltaic panel is 1000 W/m 2 fora surface temperature of 25°C; however,the efficiency will drop by 0.485% per1°C temperature increment.The system can be used on lakes, ponds or dams.
Validation of a Model for Operation Optimization of a Regional Water Supply System

Sustainable use of water resources requires a modern approach for complex water systems management based on system’s modeling, as unsung operation alternatives may only be devised and tested through a model. The now available IT computing tools enable setting the traditional modelling methodologies for planning and operation of such systems in a new framework. The present work deals with the development of decision support models for optimizing the operation of complex water supply systems with multiple uses and focuses on the validation of the optimization model of the regional water supply systems managed by an Italian water utility. The software used is Aquator, a state-of-the-art commercial tool for generic water resources system simulation and operational optimization. The paper shows and comments the results of the validation of the model and uses them to draw some general principles for the validation of such kind of models: in fact, operational optimization models are conceived for the enhancement of systems management and performance. Consequently, while on the one side model output is expected to reflect the actual state of the system, on the other it can point out significant management enhancements.
Microdamage Caused by Fatigue Loading in Human Cancellous Bone: Relationship to Reductions in Bone Biomechanical Performance

Vertebral fractures associated with osteoporosis are often the result of tissue damage accumulated over time. Microscopic tissue damage (microdamage) generated in vivo is believed to be a mechanically relevant aspect of bone quality that may contribute to fracture risk. Although the presence of microdamage in bone tissue has been documented, the relationship between loading, microdamage accumulation and mechanical failure is not well understood. The aim of the current study was to determine how microdamage accumulates in human vertebral cancellous bone subjected to cyclic fatigue loading. Cancellous bone cores (n = 32) from the third lumbar vertebra of 16 donors (10 male, 6 female, age 76±8.8, mean ± SD) were subjected to compressive cyclic loading at σ/E0 = 0.0035 (where σ is stress and E0 is the initial Young’s modulus). Cyclic loading was suspended before failure at one of seven different amounts of loading and specimens were stained for microdamage using lead uranyl acetate. Damage volume fraction (DV/BV) varied from 0.8±0.5% (no loading) to 3.4±2.1% (fatigue-loaded to complete failure) and was linearly related to the reductions in Young’s modulus caused by fatigue loading (r2 = 0.60, p<0.01). The relationship between reductions in Young’s modulus and proportion of fatigue life was nonlinear and suggests that most microdamage generation occurs late in fatigue loading, during the tertiary phase. Our results indicate that human vertebral cancellous bone tissue with a DV/BV of 1.5% is expected to have, on average, a Young’s modulus 31% lower than the same tissue without microdamage and is able to withstand 92% fewer cycles before failure than the same tissue without microdamage. Hence, even small amounts of microscopic tissue damage in human vertebral cancellous bone may have large effects on subsequent biomechanical performance.
A SOUND APPROACH TO IMPROVING READING: RESPONDING TO STUDENTS’ LEARNING STYLES

One of the first studies that identified elementary school students’ predispositions to learning either in quiet or with sound present revealed many youngsters’ strong preferences for one or the other treatments. The study described in this article received national recognition for the quality of its design and focus. Students achieved significantly higher standardized test scores when taught in congruent, rather than incongruent, environments.
Affective and health-related outcome expectancies for physical activity in older adults

This study tests the effects of affective and health-related outcome expectancies on physical exercise, assuming stronger direct and indirect (via intention) effects from affective outcome expectancy to physical exercise than from health-related outcome expectancy to exercise. Physical exercise and social cognitive variables were assessed at baseline, and 6- and 12-month follow-up in 335 older adults (60–95 years of age). Applying structural equation modelling, there was a direct effect from affective, but not from health-related outcome expectancy on intentions and behaviour. Also, the indirect effect from self-efficacy on physical exercise via affective outcome expectancy was significant, whereas the mediation via health-related outcome expectancy was not. These findings emphasise the relative importance of affective versus health-related outcome expectancies in predicting intentions and physical exercise in older adults and highlight the importance to separate these facets at a conceptual level to enhance both theory development and health promotion.
Quality of Life of Victims Bullies, and Bully/Victims Among School-Aged Children in the Netherlands

Two studies were conducted to examine the Quality of Life (QoL) of victims, bullies and bully/victims among Dutch school-aged children. Study 1 studied associations of QoL dimensions with self-reported victimisation in the Dutch sample from the KIDSCREEN Project (N = 1,669). Study 2 examined QoL of self-reported and peer-nominated victims, bullies and bully/victims using baseline data from an evaluation study of an anti-bullying intervention (N = 3,483). In both studies victimisation appeared to be consistently associated with statistically significantly poorer child and adolescent QoL in regard to all QoL dimensions measured. The strongest associations were found with the QoL dimension Moods and Emotions and least with QoL regarding Physical Well-Being. This indicates that victims of bullying are generally less happy and cheerful, feel sad and depressed more often, have a less positive perception of themselves and are less positive about going to school than non-involved children. Active bullying was only associated with decreased QoL in regard to School Environment. That is, bullies are on average less positive about going to school and attending classes than non-involved children are. Finally, QoL of bully/victims mostly resembled that of victims; whereas the association of being a bully/victim was strongest with the QoL dimension Moods and Emotions, the association with QoL regarding Physical Well-Being appeared to be statistically non-significant.
Effect of smoking on single dose pharmacokinetics of phenobarbital

In order to determine interaction of smoking with single dose pharmacokinetics of phenobarbital, a 60 mg tablet of the drug was given to 12 healthy male subjects in two groups (6 smokers and 6 non‐smokers) in a double blind study. An HPLC method using UV detection was developed to assess phenobarbital in plasma of the subjects. Pharmacokinetic parameters were calculated and compared in the two groups. Pharmacokinetic parameters of the two groups were not significantly different in the two groups (p<0.05). The results show no considerable effect of cigarette smoking on phenobarbital pharmacokinetics, which is in agreement with enzyme studies performed previously.

Reengineering the Collision Coupling and Diffusion Mode of the A2A-adenosine Receptor

Background: The A2A receptor engages Gs by restricted collision coupling and lacks a palmitoyl moiety in its C terminus. Results: Engineering palmitoylated cysteine into the C terminus relieved restricted collision coupling and resulted in accelerated diffusion of the agonist-liganded A2A receptor. Conclusion: Restricted collision coupling arises from limits imposed on receptor diffusion. Significance: Agonist induced confinement of the A2A receptor in a structure consistent with a lipid raft. The A2A-adenosine receptor undergoes restricted collision coupling with its cognate G protein Gs and lacks a palmitoylation site at the end of helix 8 in its intracellular C terminus. We explored the hypothesis that there was a causal link between the absence of a palmitoyl moiety and restricted collision coupling by introducing a palmitoylation site. The resulting mutant A2A-R309C receptor underwent palmitoylation as verified by both mass spectrometry and metabolic labeling. In contrast to the wild type A2A receptor, the concentration-response curve for agonist-induced cAMP accumulation was shifted to the left with increasing expression levels of A2A-R309C receptor, an observation consistent with collision coupling. Single particle tracking of quantum dot-labeled receptors confirmed that wild type and mutant A2A receptor differed in diffusivity and diffusion mode; agonist activation resulted in a decline in mean square displacement of both receptors, but the drop was substantially more pronounced for the wild type receptor. In addition, in the agonist-bound state, the wild type receptor was frequently subject to confinement events (estimated radius 110 nm). These were rarely seen with the palmitoylated A2A-R309C receptor, the preferred diffusion mode of which was a random walk in both the basal and the agonist-activated state. Taken together, the observations link restricted collision coupling to diffusion limits imposed by the absence of a palmitoyl moiety in the C terminus of the A2A receptor. The experiments allowed for visualizing local confinement of an agonist-activated G protein-coupled receptor in an area consistent with the dimensions of a lipid raft.
Supporting Mobile Language Learning outside Classrooms

The continuous development of wireless and mobile technologies has allowed the creation of an additional platform for supporting learning, one that can be embedded in the same physical space in which the learning is taking place. This paper describes a computer supported ubiquitous learning environment for language learning, called LOCH (language-learning outside the classroom with handhelds). In the environment, the teacher assigns field activities to the students, who go around the town to fulfil them and share their individual experiences. The main aim of this project, called One Day Trip with PDA, was to integrate the knowledge acquired in the classroom and the real needs of the students in their daily life
Developing a New Instrument for Assessing Acceptance of Change

This article focuses on the usefulness of going beyond the concept of resistance to change and capitalizing on the use of a model that includes positivity and acceptance of change. We first discuss the theoretical background of this new construct in the work and organizational fields and then evaluate the psychometric properties of a new measure for assessing acceptance of change. The results of exploratory factor analysis indicated a factor structure with five principal dimensions; besides confirmatory factor analysis (CFA) goodness of fit indices indicated a good fit of the model to the data. All the dimensions showed good values of internal consistency. The results of the present study indicate that the Acceptance of Change Scale (ACS) is a brief and easily administered instrument with good psychometric properties that can promote the development of clients' strengths and the growth of a sense of Self, thereby helping them choose their own way without losing any opportunities in their lives and their work.
Manufacturing Space: Gendered Cityscapes and Industrial Images in Dundee

Recent interest in the material and discursive construction of built environments has largely focused on the iconic skyscraper as a symbol of ‘modern’ global and corporate power. Within this theoretical frame, industrial landscapes are given short shrift. I seek to redress this by taking the example of Victorian and Edwardian Dundee and exploring the construction of a specific manufacturing space by the city's industrial elite. Moreover, this paper moves beyond traditional analyses to take a specifically gendered look at this process. I argue that, while women numerically dominated Dundee's jute industry, it was men as jute-company directors who laid claim to place through their role in image making. The paper starts by looking at the processes of building and elaborating industrial space and power through an investigation of the fabric of the city. It then explores how such materiality was accompanied by and represented in a range of industrial imagery. Unpacking this landscape—pointing to the construction and subversion of gendered binaries and the recursive relationship between the material and immaterial—helps us see how industrial elites fashioned and reaffirmed their identity and power through the mobilisation of a set of representational tactics, creating a particularly gendered manufacturing (of) space.
Children's treatment by peers: Victims of relational and overt aggression

Abstract Past research on peer victimization has focused on maltreatment through overtly aggressive behaviors. Although a relational form of aggression has been identified in recent research, studies of the victims of relational aggression have not yet been conducted. The present research was designed as a first attempt to address this issue. Four goals were pursued (n = 474; third- through sixth-grade children): (a) development of a self-report measure of victimization through relational and overt aggression; (b) assessment of the relation between overt victimization and relational victimization; (c) assessment of gender, grade, and sociometric status group differences in victimization; and (d) evaluation of the relation between victimization and social-psychological adjustment. Results showed that the newly developed victimization measure had favorable psychometric properties and that most of the identified victims were the targets of cither relational or overt aggression, but not both. Further, rejected children were more relationally and overtly victimized than their better accepted peers, and boys were more overtly victimized than girls. Finally, relational victimization, overt victimization, and the lack of prosocial treatment by peers were all significantly related to social-psychological adjustment difficulties (e.g., depression, loneliness).
Wilson line correlators in two-dimensional noncommutative Yang-Mills theory

We study the correlator of two parallel Wilson lines in two-dimensional non-commutative Yang-Mills theory, following two different approaches. We first consider a perturbative expansion in the large-N limit and resum all planar diagrams. The second approach is non perturbative: we exploit the Morita equivalence, mapping the two open lines on the non-commutative torus (which eventually gets decompacted) in two closed Wilson loops winding around the dual commutative torus. Planarity allows us to single out a suitable region of the variables involved, where a saddle-point approximation of the general Morita expression for the correlator can be performed. In this region the correlator nicely compares with the perturbative result, exhibiting an exponential increase with respect to the momentum p.
The Effect of Expected Variability of Product Quality and Attribute Uniqueness on Family Brand Evaluations

This research investigates the processes by which consumers evaluate a family brand on the basis of information about its products. Findings from three experiments suggest that the expected variability of individual product quality within the brand and attribute uniqueness systematically influence information processing and family brand evaluations. On-line (vs. memory-based) processing of information to form family brand judgments is more likely when expected variability is low (vs. high) and when the attributes are shared (vs. unique) within the family brand. These different processes lead to differences in family brand evaluations due to primacy (on-line processing) and recency (memory-based processing) effects.

A Comparison of Urban with Rural Support Networks: Liverpool and North Wales

Abstract This paper compares findings on the distribution of support networks in the City of Liverpool and in rural communities in North Wales. It demonstrates that while support network type is highly correlated with a wide range of demographic and social variables in both urban and rural samples, the nature of the relationships are not always comparable. The paper shows how cultural, migration and socio-economic factors interact to affect the formation of different types of support networks. As a result of a more stable elderly population, more old people in Liverpool have network types able to provide a high level of informal care and support.
Toward understanding suicide among youths: results from the White Mountain Apache tribally mandated suicide surveillance system, 2001-2006.

OBJECTIVES We examined suicide and suicide attempt rates, patterns, and risk factors among White Mountain Apache youths (aged < 25 years) from 2001 to 2006 as the first phase of a community-based participatory research process to design and evaluate suicide prevention interventions. METHODS Apache paraprofessionals gathered data as part of a tribally mandated suicide surveillance system. We compared findings to other North American populations. RESULTS Between 2001 and 2006, 61% of Apache suicides occurred among youths younger than 25 years. Annual rates among those aged 15 to 24 years were highest: 128.5 per 100 000, 13 times the US all-races rate and 7 times the American Indian and Alaska Native rate. The annual suicide attempt incidence rate in this age group was 3.5%. The male-to-female ratio was 5:1 for suicide and approximately 1:1 for suicide attempts. Hanging was the most common suicide method, and third most common attempt method. The most frequently cited attempt precipitants were family or intimate partner conflict. CONCLUSIONS An innovative tribal surveillance system identified high suicide and attempt rates and unique patterns and risk factors of suicidal behavior among Apache youths. Findings are guiding targeted suicide prevention programs.
How to Measure the Control-flow Complexity of Web Processes and Workflows

Several Web process and workflow specification languages and systems have been developed to ease the task of modeling and supporting business processes. In a competitive e-commerce and e-business market, organizations want Web processes and workflows to be simple, modular, easy to understand, easy to maintain and easy to re-engineer. To achieve these objectives, one can calculate the complexity of processes. The complexity of processes is intuitively connected to effects such as readability, understandability, effort, testability, reliability and maintainability. While these characteristics are fundamental in the context of processes, no methods exist that quantitatively evaluate the complexity of processes. The major goal of this chapter is to describe a measurement to analyze the control-flow complexity of Web processes and workflows. The measurement is to be used at design-time to evaluate the complexity of a process design before implementation.
Set-shifting abilities, central coherence, and handedness in anorexia nervosa patients, their unaffected siblings and healthy controls: Exploring putative endophenotypes

Abstract Objective. There is consistent evidence that anorexia nervosa (AN) is associated with an impairment of set-shifting abilities and central coherence. No study to date investigated handedness in AN. Our aim was to study set-shifting abilities, central coherence, and handedness in subjects with lifetime AN, in a sample of unaffected sisters and in healthy controls, in order to explore their suitability as endophenotypes of AN. Methods. The Edinburgh Handedness Inventory and several neuropsychological tasks (Wisconsin Card Sorting Test, Trail Making Test, Rey-Osterrieth Complex Figure Test, Overlapping Figures Test, Object Assembly and Block Design) were administered to 153 subjects with lifetime AN, 28 unaffected sisters and 120 healthy controls. Results. AN subjects and their healthy sisters showed poorer performances on most tasks investigating set-shifting and central coherence. In addition, we did not find any differences between long-term recovered subjects, weight-restored AN patients and those in an acute phase of their illness. AN subjects were significantly more likely to be left-handed than healthy controls (OR=2.8, 95% C.I. 1.1–7.2). Conclusions. Set-shifting and central coherence seem to be promising cognitive endophenotypes that might help in the understanding of the pathogenetic processes involved in AN. Further studies on larger samples are needed to explore the generalizability and implications of our findings concerning handedness.
