Knowledge sharing and firm innovation capability: an empirical study

Purpose – The study sets out to examine the influence of individual factors (enjoyment in helping others and knowledge self‐efficacy), organizational factors (top management support and organizational rewards) and technology factors (information and communication technology use) on knowledge sharing processes and whether more leads to superior firm innovation capability. Design/methodology/approach – Based on a survey of 172 employees from 50 large organizations in Taiwan, this study applies the structural equation modeling (SEM) to investigate the research model. Findings – The results show that two individual factors (enjoyment in helping others and knowledge self‐efficacy) and one of the organizational factors (top management support) significantly influence knowledge‐sharing processes. The results also indicate that employee willingness to both donate and collect knowledge enable the firm to improve innovation capability. Research limitations/implications – Future research can examine how personal traits (such as age, level of education, and working experiences) and organizational characteristics (such as firm size and industry type) may moderate the relationships between knowledge enablers and processes. Practical implications – From a practical perspective, the relationships among knowledge‐sharing enablers, processes, and firm innovation capability may provide a clue regarding how firms can promote knowledge‐sharing culture to sustain their innovation performance. Originality/value – The findings of this study provide a theoretical basis, and simultaneously can be used to analyze relationships among knowledge‐sharing factors, including enablers, processes, and firm innovation capability. From a managerial perspective, this study identified several factors essential to successful knowledge sharing, and discussed the implications of these factors for developing organizational strategies that encourage and foster knowledge sharing.
Understanding student behavioral engagement: Importance of student interaction with peers and teachers

ABSTRACT Recent theoretical conceptualizations of student engagement have raised questions about how to measure student engagement and how engagement varies not only across schools, but also within school and within classrooms. The authors build on existing research on student behavioral engagement and extend this research to emphasize a continuum of disengagement, active engagement, and passive engagement. They review common approaches to measuring engagement and highlight areas where new theoretical conceptualizations of engagement require new approaches to measurement. The authors analyze how student behavioral engagement changed depending on the context and demonstrate the need of a finer scale of engagement. They find there was not a uniform association of higher behavioral engagement and student interaction with peers, but it was the interaction with other students and the teacher that was predictive of increased engagement. Their work suggests that disaggregating behavioral engagement into disengagement, active engagement, and passive engagement has important research and conceptual implications.
The thick disc of the Galaxy: sequel of a merging event.

Accurate characterization of thick disc properties from recent kinematic and photometric surveys provides converging evidences that this intermediate population is a sequel of the violent heating of early disc populations by a merging satellite galaxy. The thick disc population is revisited under the light of new data in a number of galactic sample fields. Various thick disc hypotheses are fitted to observational data through a maximum likelihood technique. The resulting characteristics of the thick disc are the following: a scale height of 760 ± 50pc, with a local density of 5.6 ± 1% of the thin disc. The scale length is constrained to be 2.8 ± 0.8kpc, well in agreement with the disc scale length (2.5 ± 0.3kpc). The mean metallicity of the thick disc is found to be -0.7 ±0.2 dex, with no significant metallicity gradients. These photometric constraints in combination with kinematic data give new constraints on the thick disc formation. We show that thick disc characteristics are hardly compatible with a top-down formation scenario but fully compatible with a violent merging event arising at the early thin disc life time as described by Quinn, Hernquist & Fullagar (1993).
Genetic algorithms in astronomy and astrophysics

Genetic algorithms (GAs) emulate the process of biological evolution, in a computational setting, in order to generate good solutions to difficult search and optimisation problems. GA-based optimisers tend to be extremely robust and versatile compared to most traditional techniques used to solve optimisation problems. This review paper provides a very brief introduction to GAs and outlines their utility in astronomy and astrophysics.
SciMAT: A new science mapping analysis software tool

This article presents a new open-source software tool, SciMAT, which performs science mapping analysis within a longitudinal framework. It provides different modules that help the analyst to carry out all the steps of the science mapping workflow. In addition, SciMAT presents three key features that are remarkable in respect to other science mapping software tools: (a) a powerful preprocessing module to clean the raw bibliographical data, (b) the use of bibliometric measures to study the impact of each studied element, and (c) a wizard to configure the analysis. © 2012 Wiley Periodicals, Inc.
Perceptions of risk on vacation among visitors to Istanbul

PurposeThe purpose of this paper is to focus on the perceptions of risk from specific crimes held by tourists at the start of their vacation in the Turkish city of Istanbul.Design/methodology/approachThe paper describes findings from Phase 1 of a two-phase research programme, during which 210 arrivals at the Ataturk airport were asked about their perceptions of their safety from crime while in the city and their intentionsvis-à-visthe adoption (or otherwise) of basic safety precautions, using a 32-question self-completion questionnaire.FindingsThe findings confirm those of earlier studies that tourists, unlike citizens in general, tend to have low expectations of their vulnerability to crime. However, variables associated with fear in conventional surveys were not generally related to the perceptions of risk. The clearest association was between prior knowledge of crime in Istanbul and perceptions of risk. The lack of any strong relationship between perceptions of risk and intent to adopt safety precautions is then discussed.Research limitations/implicationsThe study is limited to visitors to one city and to English-speaking tourists.Practical implicationsThe implication here is that if tourist centres wish to reduce crime it is not sufficient to focus on “educating” tourists on the dangers, but that more emphasis should be placed on crime prevention methods that put the onus on the host environment.Social implicationsFrom a criminological perspective, two points appear particularly important. First, the relationship between fear (in all its manifestations) and risk is not constant. It may differ in different physical and social contexts. Second, if, following routine activity theory, policy makers wish to focus on changing people’s behaviour in order to maximise their safety, in different contexts different publics may vary in their willingness or resistance to change.Originality/valueThis study is original as it focusses on tourists to a specific destination at the beginning of their holiday.
Intervening in domestic violence as a police task: legal reform and policing versus citizens’ perspective

ABSTRACT Violence in Western societies has received increased public and legal attention during the past few decades, while simultaneously, evidence of decreased violent behaviour has been identified. A specific type of violence that has undergone changes in visibility and increased legal intervention is domestic violence (DV). Have people become more sensitive to all kinds of violence? In this case, DV would not stand out as a crime demanding increasing police intervention. In this article, the public’s perceptions of the importance of intervening in DV as a police task are analysed. Comparisons with the assessed importance of other types of police tasks are made to evaluate the changes in a broader attitudinal context, and official police statistics are reflected against the trends identified from the survey data. In the results, DV stands out in the comparison of change in the importance of police tasks. The hypothesis of increased cultural sensitivity is not confirmed concerning all types of crimes – or even violent crimes. The results can be understood to support the theory about increased cultural sensitivity concerning an issue previously seen as a private matter rather than a criminal act and police matter – DV.
An NTS2 Analog Enhances the Analgesic Effects of Morphine in an Animal Model of Persistent Pain and Does not Exhibit Tolerance

The analgesic efficacy of neurotensin agonists depends on their activation of two receptor subtypes, NTS1 and/or NTS2. In this study we determined the role of NTS2 in an animal model of persistent pain (intraplantar injection of formalin) with the use of the NTS2-selective analog, NT79 and NTS2-knockout mice (NTS2 -/- ). Wild type (WT) and NTS2 -/- mice were pretreated with NT79 and tested for formalin-induced lifting and biting. Additionally, the effect of repeated administration of NT79 and morphine alone and in combination was determined in WT mice. Intraplantar injection of formalin produced the typical biphasic nociceptive response of this persistent pain model. Formalin evoked lower pain intensity in NTS2 -/- mice as compared to that for WT mice. Pretreatment with NT79 attenuated formalin- induced nociception throughout phase II in the WT mice, and in early phase II in the NTS2 -/- mice. Lifting and biting responses were attenuated, indicating spinal and supra-spinal modulation of persistent nociception. More importantly, repeated injection of NT79 enhanced, while that of morphine reduced their antinociceptive effects, respectively. Subchronic co-administration of NT79 and morphine enhanced the analgesic effect over either drug alone. These data support the role of NTS2 in modulating formalin-induced pain. Additionally, these data provide a rationale for the potential therapeutic role of NTS2-selective analogs in chronic pain management alone or in combination with morphine and without the development of tolerance.
Phase I-II Trial of Weekly Bicalutamide in Men with Elevated Prostate-Specific Antigen and Negative Prostate Biopsies

Background: Men with elevated prostate-specific antigen (PSA) and negative prostate biopsies are at risk for prostate cancer. The antiandrogen bicalutamide has a prolonged half-life, thus potentially allowing an intermittent administration to retain activity while reducing toxicity. We conducted a phase I-II trial of weekly bicalutamide in men with PSA >4 ng/mL and negative biopsies. Methods: Eighty subjects were nonrandomly assigned to a three-arm trial to either bicalutamide 50 mg/wk (n = 26) or 100 mg/wk (n = 28) or no treatment (n = 26) for 6 months. Blood samples were obtained at 0, 3, and 6 months, and prostate biopsies were repeated after 6 months. The outcome measures were 6-month changes of tissue Ki-67 (primary end point), high-grade prostatic intraepithelial neoplasia (HG-PIN), proliferative inflammatory atrophy, circulating PSA, and sex hormones. Results: Ki-67 expression was higher in HG-PIN than in normal tissue (10% versus 3%; P < 0.01) but was not modulated by bicalutamide in normal luminal cells. A trend toward an improvement of HG-PIN status was found in treated subjects (26% improved, 60% had no change, 15% worsened) as compared with the no-treatment arm (4% improved, 83% had no change, 13% worsened; P = 0.07). Proliferative inflammatory atrophy prevalence was not reduced by bicalutamide. Bicalutamide reduced PSA by 50% in both arms and raised testosterone and estradiol levels. Asymptomatic breast swelling was noted in 40% of the treated cases. Conclusions: A weekly administration of bicalutamide seems to be reasonably safe and shows an encouraging signal of activity on HG-PIN prevalence, supporting further studies of this schedule in men at high risk despite the negative primary end-point findings on Ki-67.
Indoor space subdivision for indoor navigation

There are a number of great attempts to develop an indoor navigation that provide the most optimal path and guidance. Finding a way in large buildings can be a challenging task. In order to represent the real situation to a maximum extent, a representation of the whole room as one single indivisible object is not enough as such representation is very abstract and this could make the navigation difficult and may result into inefficient route planning. In order to provide a smooth navigation path, the presence of humans within the indoor environment and the natural movement of individuals should be taken into consideration. In this paper a two-step indoor space subdivision for indoor navigation is described. Firstly, the indoor space is subdivided into navigable and non-navigable areas considering human perceptions of the environment and human behaviour. Secondly, the navigable space is subdivided applying a constrained Delaunay triangulation. Finally, the guidelines for generation of the navigation network and verification of the proposed model are presented.
“ Endogenous ” Relative Concerns : The Impact of Workers ’ Characteristics on Status and Profits in the Firm April

This paper shows that it is individually rational for agents in a firm to develop and exhibit status concerns. Workers are, by their choices of status concerns, able to transfer surplus from the the firm to themselves. Further, relative concerns are shaped by the relative strengths and weaknesses of the workers in the firm. Finally, and surprisingly, a firm’s profit is reduced (relative to the benchmark moral-hazard model) by workers who exhibit such “endogenous” relative concerns.

Expressions of Attitudes in Students’ Narrative Writing: An Appraisal Analysis

This article investigated attitude, one of subsystem appraisal, in the English as a Foreign Language (EFL) university students’ narrative writings. Five narrative writing was selected purposefully from undergraduate students of the English Department at a local private university in Central Java. The findings demonstrate that the affect is the most dominant subsystem of attitude used in the students’ narrative writing to convey feelings and emotion of characters and events in the stories in order to make the readers involved in the stories. The prominent finding of this research implies that most students used expressions of attitudes which belong to basic English words and repetition of same words. This present research suggests English language teachers and lecturers pay more attention to the explicit teaching of attitudinal words usage in writing, especially narrative writing.
Towards the General Network Traffic Estimation

The amount and distribution of traffic, generated inside a computer network, is an essential input into topology design and optimization as well as optimal routing strategies. The paper extends the basic method for estimating the amount of backbone traffic from information infrastructure at network access points. The initial traffic distribution is generalised, access points with special properties are introduced and different kinds of traffic are identified (inner, foreign and transit traffic). Based on the refined estimations, end-to-end traffic amounts are calculated and traffic matrix is formed, ready to proceed into next steps of network design.
DSTree: A Tree Structure for the Mining of Frequent Sets from Data Streams

With advances in technology, a flood of data can be produced in many applications such as sensor networks and Web click streams. This calls for efficient techniques for extracting useful information from streams of data. In this paper, we propose a novel tree structure, called DSTree (Data Stream Tree), that captures important data from the streams. By exploiting its nice properties, the DSTree can be easily maintained and mined for frequent itemsets as well as various other patterns like constrained itemsets.

Estimation of genetic parameters and genotype effects for crossing constructions of Hungarian Pigs

During the last two decades the BLUP breeding value estimation became a wide-spread procedure in every animal breeding sector. The Hungarian pig breeding sector was no exception and after an extremely long transition period (more than 10 years) the BLUP procedure became official in 2009 (MGSZH, 2009). Since then the genetic merit of the Hungarian pig populations are obtained by means of BLUP evaluations that are based on the various performance test data (field and station tests). Generally the BLUP procedure was developed for purebred animals. An overview about the application of BLUP in the various breeding programs and about the various BLUP models was given by Komlósi (1999) and Szőke and Komlósi (2000). However applying crossing is one of the main characteristics of the pig breeding sector. In order to evaluate crossbreds one possibility is to use pooled datasets and pedigrees of all genotypes participating in a given cross. Although the genetic parameters of the Hungarian purebred pig populations were reported by several studies (Csató et al., 2002; Csató et al., 2004; Farkas, 2008; Nagy et al., 2009) no relevant literature is available about the genetic parameters of crossbreds or about the estimated genotype effects describing the efficiency of the different crosses. These were the objectives of this study. MATERIALS AND METHODS
On the Value of Cooperative Buyer-Seller Relationships in Industrial Markets

During the last years cooperative buyer-seller relationships in industrial markets were more and more discovered as instruments of strategy. While quite a number of publications emphasize the role of the concept of relationship value for the management of cooperative buyer-seller relationships, only very limited empirical research has been done on this topic so far. Therefore, this paper describes a large-scale, three-step empirical study that is aimed at conceptualizing and measuring the value of cooperative business relationships from both buyer and supplier perspective using methods of multivariate analysis. Results show that benefits and sacrifice may be considered as building blocks of relationship value, with relationship benefits being the main value drivers.
Low Levels of after School-Hours Social Interaction and Physical Activity of 5-7 Year Olds

As part of a cluster randomized controlled trial (Bundy et al., 2017), the after school-hours activities of 5-7 year old children were recorded by parents and other adult carers on four consecutive weekdays between 3:30pm-7:00pm. Records of time use showed most time was spent indoors in activities involving low levels of physical activity. The most-frequently-recorded activity was screen time, accounting for approximately one quarter of all activities. Higher levels of physical activity were reported when children were outdoors (19.5% of time) and/or with peers (9.58%). If an adult was present, highest activity levels of children occurred when the child was with a teacher/carer (6.07%). Although concern is frequently raised about children spending too much time in organized activities, these structured forms of out-of-school choices accounted for only 8.09% of recordings. The results of the current study strengthen the evidence base, supporting the need to optimise out-ofschool times with more developmentally important social and physical contexts. We discuss ways in which context may support or inhibit opportunities physical activity in after school-hours activities.
The effects of teacher talk on L2 learners' comprehension

In the field of the second language acquisition, a number of studies have investigated the phenomenon of linguistic input to L2 learners in order to determine its role in the process of acquiring a target language. In classroom settings, such input is provided by the L2 teacher speech to nonnative speakers of the second language. Research indicates that teacher talk (TT) directed to L2 learners is characterized by discourse, syntactic, lexical, and phonological modifications. However, only a few studies provide evidence about the effects of TT phonetic/phonological adjustments on the nonnative comprehension. In the present study, nonnative listeners participated in an auditory sentence-final keyword transcription task for teacher talk and conversational speech. Results revealed that NNSs exhibited a significant main effect of speech type, with teacher talk more intelligible than conversational speech. However, the pattern of results in this study showed that the magnitude of speech type benefit differs depending on different levels of various factors such as level of learner proficiency, talker, and sentential context. The results from this study are interpreted in terms of their implications for providing comprehensible input to L2 learners in order to assist their language acquisition.
