A precursor to social interaction is social understanding. Every day, humans observe each other and on the basis of their observations "read people's minds," correctly inferring the goals and intentions of others. Moreover, this ability is regarded not as remarkable, but as entirely ordinary and effortless. If we hope to build robots that are similarly capable of successfully interacting with people in a social setting, we must endow our robots with an ability to understand humans' intentions. In this paper, we propose a system aimed at developing those abilities in a way that exploits both an understanding of actions and the context within which those actions occur.

This study explores student achievement, sense of social community, and sense of learning community (Rovai, 2002) in two sections of an online course taught concurrently by the same instructor. One section was delivered in a fully asynchronous format; the other incorporated weekly synchronous lectures using an Adobe Connect environment. Students were randomly assigned to one of the two sections but allowed to change sections (before the semester began) if unwilling or unable to participate in weekly Adobe Connect meetings. Data included grades on course assignments, final course grades, end-of-course evaluations, and responses to the Classroom Community Inventory (Rovai, Wighting & Lucking, 2004). No significant differences were found on measures of academic achievement, student satisfaction, social community, or learning community between the two sections. © 2015 Sloan Consortium.

Online reviews as a major form of user-generated contents play a strategic role in eliminating information asymmetry and facilitating transactions in electronic markets. To improve market efficiency, many online retailers use helpfulness voting as a crowdsourcing strategy to identify and rank online reviews. In this study, we analysed a data set of 2187 reviews as well as more than two months’ review ranking data collected from six best-selling products on amazon.com. We found that a disproportionately higher percentage of votes went to early-posted lengthy reviews due to the Matthew effect. We also found that early reviews, once identified as most helpful, could maintain their top ranking status throughout the product life cycle because of the Ratchet effect. The implications of these findings were discussed and strategies for how to mitigate negative impacts of such effects by online retailers were suggested. © 2015, Institute of Information Management, University of St. Gallen.

Denotational semantics is an approach for giving a mathematical meaning to programming languages and systems. It gives the language designers a tool for high level abstract definitions. In aspect oriented programming, advice is weaved in designated locations of an underlying program specified by a pointcut expression. It is the job of the language implementer to specify how weaved code gets to be inserted into the proper location. Current denotational semantics of languages do not have the necessary constructs for accepting this weaved code. In this paper, we preset a denotational semantics formal description that embodies the representation of constructs to be woven by some aspect. It illustrates the a formal description of the mechanism of where and how woven advice is inserted. The semantics presented are intended to be a general baseline for the use of any advice in any random joinpoint. © 2016 IEEE.

Previous researchers who applied cognitive dissonance theory to charitable giving found that giving is for many donors a means of acting consistently with their self-concepts as rational and moral beings. The present study extends this inquiry by investigating how "rationality" and "morality" are culturally constructed norms. Donor communications are effective insofar as their use of language reproduces the expectations of the stakeholder community's shared culture. This finding is indicated by the author's extensive ethnographic fieldwork in a Baptist denomination in the United States. The capacity of professional leaders to arouse, preempt, or reduce members' cognitive dissonances over giving derived from language use that activated (as it simultaneously reified) concepts and associations approved by their Baptist subculture. Building on this and previous studies, the present author proposes a process model for pre- and post-decision cognitive dissonance over charitable giving. © 2014 International Society for Third-Sector Research and The Johns Hopkins University.

How does the Web affect our dependence on different shopping information sources? We compared the perceived importance of four decision sources (self-evaluation, traditional word-of-mouth or WOM, electronic WOM or eWOM, and expert opinion) under three circumstances (one cannot use the Web, one can only use the Web, one can use both) for 6 different types of products (2 search, 2 experience, and 2 credence goods). The data collected from 549 consumers show that the importance of eWOM to consumer purchase decision-making is rather limited to credence goods despite the popularity of eWOM. In addition, Web access increases consumers' confidence in self-evaluation over WOM for search goods. In contrast, the exclusive reliance on the Web does not increase the confidence in self-evaluation for experience and credence goods. Implications and future research agendas are discussed.

Published information extraction (IE) research generally discusses the technological improvement of IE software, yet little addresses the valuable application of such technology. IE and content analysis together enhance the rigor of qualitative research through computer based content analysis. We use CAINES to illustrate an effective application of IE and computer aided content analysis on eWOM reviews. CAINES is a system based on linguistic techniques that can extract and analyze online movie reviews. In this research we demonstrate how CAINES is able to analyze the most important factor a moviegoer considers when rating a movie online. CAINES extracted and analyzed movie reviews from 18 action and adventure movies consisting of 20,679 individual reviews. By using CAINES we were able to show that storyline is most important to moviegoers and they tend to leave more positive than negative reviews. Our results also reveal that reviewers mainly discuss their personal evaluation of the movie, rather than discouraging or encouraging readers to see the movie.

The helpfulness rating of Amazon product review, a popular vote feature used by Amazon to rank product reviews and display them to online shoppers, has important implications for online shopping decisions. This research investigates how objective those helpfulness ratings are. The general assumption is that the ratings are representative views of the shoppers. However, previous studies on product reviews indicate bias may also exist among helpfulness ratings. Using the survey questionnaire, the study found that there were indeed significant differences between the helpfulness ratings displayed at Amazon.com and those from a simulated online shopper population. The survey results also show that there are evidences of rating differences by gender, age, ethnicity, income and mobile device use for shopping. Thus the true ratings on online user reviews may well be quite different from what we see at Amazon.com. Implications and limitations of this research are discussed. © 2012 Springer-Verlag Berlin Heidelberg.

This paper discusses biogas production in East Africa and the implications to household income and sustainable development. A household model that links livestock, biogas and crop production is analyzed. A base model was compared with three scenarios with an increase in crop yield from the use of bioslurry. The results demonstrated that investing in biogas plants only for energy replacement would not give farmers positive benefits at the current interest rates. The combined effects of lower interest and increases in yield could encourage farmers' investments in biogas plants that could lead to increases in household income and food security and reduction in deforestation in the region. © 2015 Elsevier Ltd.

In the overall ownership cost of enterprise system, the maintenance cost consists of a major percentage. During the lifetime of an enterprise system, process customization is the most frequent maintenance efforts. However, current processing method has limited scalability and efficiency. In this case study, we explained how a scalable and efficient customization processing method was implemented. This method used the carbon emission trading mechanism to facilitate the cost benefit analysis of customization request. It also used distributed processing principle to improve the overall processing efficiency.

This study develops and empirically tests a conceptual framework to investigate the antecedents of manufacturers' supply chain agility and the connection of their agility with performance in an emerging economy. Drawing upon the information theory, this study argues that technical (IT capability) and relational factors (information sharing and trust, and operational collaboration) are the antecedents of a manufacturer's supply chain agility. This study also posits that cost efficiency mediates the relationship between agility and performance based on transaction cost economics. Employing path analysis, this study shows that strong associations exist between a manufacturing firm's IT capability and operational collaboration with suppliers and its supply chain agility. The results also indicate the significant mediating effect of cost efficiency between the manufacturer's supply chain agility and performance. Implications are discussed and future research directions are also suggested. © 2013 Elsevier B.V.

The development of biochemistry and molecular biology has revealed an increasingly important role of compounds in several biological processes. Like the aptamer-protein interaction, aptamer-compound interaction attracts increasing attention. However, it is time-consuming to select proper aptamers against compounds using traditional methods, such as exponential enrichment. Thus, there is an urgent need to design effective computational methods for searching effective aptamers against compounds. This study attempted to extract important features for aptamer-compound interactions using feature selection methods, such as Maximum Relevance Minimum Redundancy, as well as incremental feature selection. Each aptamer-compound pair was represented by properties derived from the aptamer and compound, including frequencies of single nucleotides and dinucleotides for the aptamer, as well as the constitutional, electrostatic, quantum-chemical, and space conformational descriptors of the compounds. As a result, some important features were obtained. To confirm the importance of the obtained features, we further discussed the associations between them and aptamer-compound interactions. Simultaneously, an optimal prediction model based on the nearest neighbor algorithm was built to identify aptamer-compound interactions, which has the potential to be a useful tool for the identification of novel aptamer-compound interactions. The program is available upon the request. © 2016 ShaoPeng Wang et al.

Background: Previous research on direct-to-consumer advertising (DTCA) has not focused exclusively on the African American population. Purposes: The purpose of this study was to explore African Americans' attitudes toward proactive health behaviors following exposure to DTCA of atorvastatin calcium (Lipitor, Pfizer Inc). Materials and Methods: One-hundred fifty African American patients participated in the study. Participants' functional health literacy and health locus of control were assessed. The participants were asked to view a DTCA of Lipitor, followed by face-to-face interviews. Results: After watching the DTCA of Lipitor, 89.4% of participants agreed that they would talk to their physician about their cholesterol, 88.6% agreed that they would ask their physician to test their cholesterol level, and 47.3% agreed that they would ask their physician to write them a prescription for Lipitor. Those who had a history of high cholesterol were more likely to agree to ask their physician to test their cholesterol levels. Low household income, having public health insurance, and prior experience with taking Lipitor were significant positive predictors of patients agreeing to ask their physician to write a prescription of the advertised drug. Conclusions: African American patients showed favorable attitudes toward proactive health behaviors after exposure to DTCA of Lipitor.

Drawing on the economic growth and social cognitive theory, this paper investigates the effects of management strategies-based factors (knowledge management process competence and innovation capability) and dynamic capabilities-based factors (rewards system and marketing fit) on corporate growth in the Chinese high technology firms. The results show that the knowledge management process competence, innovation capability, and marketing fit exert significant effects on corporate growth. In particular, this study identifies a significant curvilinear relationship between innovation capability and corporate growth. The findings suggest that both management strategy-based and dynamic capabilities-based factors should be considered in achieving long term corporate growth in Chinese high technology firms. These results have important implications for researchers investigating the determinants of high technology firms' growth performance in transitional economies as well as practitioners seeking to improve corporate growth. This paper concludes with a discussion of the implications and limitations of the research. © 2011 Inderscience Enterprises Ltd.

Prior network-based research on open source software (OSS) development has focused on the benefit of network ties and assumed all network ties play the same role. We adopt a fine-grained view of network relations to investigate the impact of network ties on the success of OSS development. Through examining the development of OSS projects hosted by SourceForge, we find that co-membership among project teams is an effective mechanism for building network ties, through which knowledge and expertise flows across projects in OSS community and, therefore, contributes to the success of OSS development. However, network ties among projects not only confer benefit, but also incur various cost, and due to the different growth patterns of cost and benefit, network ties have a diminishing return to project success. In addition, we find network ties of leader-follower type and follower-leader type are more beneficial to OSS success than other types of ties, and network ties connecting to projects of later development stages are more beneficial than those connecting to projects of earlier stages. Our study provides useful guidelines and suggestions as to how to leverage the knowledge and expertise of others for successful development of OSS projects. © 2013 Elsevier B.V. All rights reserved.

This study examined the ability of the Personality Assessment Inventory scores to predict noncompliance and probation revocations among a sample of sex offenders mandated to participate in community-based treatment. Scores on the Borderline Features (BOR) scale and subscales were the strongest predictors of noncompliance, with effect sizes as large as d = 1.50, outperforming scores on scales designed to predict treatment rejection and antisocial traits. Relatively low BOR cut scores (e.g., 50T, 55T) appeared to be most useful for identifying those at risk for noncompliance, suggesting that those with even moderate levels of borderline or personality disorder traits may be at risk for noncompliance. © 2013 Copyright Taylor and Francis Group, LLC.

Mainly based on pKa (NH3 +) values of amino acid, a novel graphical method without degeneracy for protein sequences has been proposed firstly, which assists in viewing, aligning and comparing multiple sequences visually. Then, a new algorithm to extract a 40-dimensional numerical vector from graphical curves has been presented to characterize protein sequences. The similar relationship among sequences is computed by Euclidean distance on corresponding numerical vectors. Finally, our method is applied for similarity analysis of protein sequences on two data sets. The results are in agreement with the acknowledged view proved by a great deal of evidence from anatomy and hence demonstrate the validity of this approach. © 2013 Bentham Science Publishers.

Consumers now have a variety of shopping information sources online and offine in making purchase decisions. How has the Web changed the perceptions of consumers regarding the relative importance of different shopping information sources? Applying the attribution principle and the least effort principle, the authors hypothesize the relative importance of self-evaluation and three types of recommendations from others (wordof-mouth or WOM, expert opinion, and electronic WOMoreWOM). The data collected from 549 consumers show that the perceived importance of WOM remains equal to or even higher than that of self-evaluation for credence goods (product quality unknown even after purchase and use) and the so-called digital goods without Web access. However, the importance of self-evaluation increases when consumers have both Web access and non-Web sources of shopping information. The Web appears to make self-evaluation by consumers more important than inputs from others. © 2011, IGI Global.

Many of the studies that have tested the Orcutt's hypothesis in trade have used aggregate trade data between one country and rest of the world. Since these studies suffer from aggregation bias, three recent studies have employed data at commodity level and have found relatively more support for the hypothesis. In this paper we test the hypothesis using commodity level data from 54 industries that trade between Turkey and the US. We find support for the notion that trade flows respond to exchange rate changes faster than to relative price changes in one-third of the industries, supporting Orcutt's conjecture. © 2016 Informa UK Limited, trading as Taylor & Francis Group

Drawing on a knowledge-based view and strategic choice theory, this study develops and empirically tests a conceptual framework to assess the effect of knowledge sharing on the development of supply chain capabilities and the effects of such capabilities on supply chain performance. Employing path analysis, it is shown that strong associations exist between the sharing of both explicit and tacit knowledge and the development of supply chain capabilities, including cost efficiency and innovation capabilities. The results also indicate significant moderating effects of cost and innovation orientations on supply chain capabilities, which in turn exert effects on the improvement of supply chain performance. Managerial and theoretical implications are discussed, and future research directions are also suggested. © 2012 Copyright Taylor and Francis Group, LLC.

RFID (radio frequency identification) is one of the system solutions for tracking and tracing objects both globally and locally using RFID tags. It is an auto-ID procedure for identifying objects automatically within a geographical area. It allows information about an object to be collected automatically without having to handle the object or enter its data manually. RFID uses tags which communicate information by radio wave through antennae on small computer chips attached to objects so that such objects may be identified, located, and tracked. This technology has found a significant areas of application in business supply chains, in medical line, in security applications, and in fact many areas of human endeavor. As Auto-ID and RFID technologies are developing at an alarming rate around the world with new information appearing daily, particularly on the Internet, this paper aims to describe the technology of RFID, the areas of applications of this technology particularly in industries, security and health care management and the potential benefits of adopting the technology. The overall aim of the paper is to sensitize Nigeria to start tapping this technology for national development and security.

Curry leaf (Murraya koenegii) is a common flavouring agent in Indian foods. This study characterised the flavonol profile of curry leaf extracted with different solvents and the relative antioxidant capacity of these extracts by quantifying phenolic constituents. Flavonols were extracted using ethanol, methanol, or acetone prior to identification and quantification using liquid chromatography coupled to atmospheric pressure chemical ionisation (APCI) mass spectrometry in tandem mode (LC-MS-MS) with negative ion detection. Major curry leaf flavonols included myricetin-3-galactoside, quercetin-O-pentohexoside, quercetin-3-diglucoside, quercetin-3-O-rutinoside, quercetin-3-glucoside, quercetin-3-acetylhexoside, quercetin-O-xylo-pentoside, kaempferol-O-glucoside, and kaempferol-aglucoside. Lag-time and TBARS tests demonstrated that curry leaf phenolics prevent cupric-ion induced oxidation of LDL. The best extraction yield was obtained with 80% ethanol. Acetone extracts provided better antioxidant activity expressed as increased lag-time formation, than did ethanol or methanol extracts. Curry leaf is a rich source of flavonols that have biological activity in vitro and further studies are warranted in regards to the potential health benefits and identification of the novel flavonols whose identities remain unknown. © 2011 Elsevier Ltd.

Objectives: To evaluate the trends in patterns of disease-modifying antirheumatic drugs (DMARDs) and biological agents use from 1999 to 2009 and to identify patient characteristics associated with different patterns of their use in a national sample of Veterans with rheumatoid arthritis (RA). Design: A retrospective cohort study. Settings: Administrative databases of the USA Department of Veterans Affairs. Participants: An incident cohort of 13 254 patients with newly diagnosed RA was identified. Primary outcome measures: Trends and choice of DMARDs and biological agents' usage, and time intervals between RA diagnosis and treatment Results: Methotrexate use as first-line agent increased from 39.9% to 57.2% over the study period (p<0.001). Although biological dispensations increased over other DMARDs and biological agents, from 3.4% to 25% from 1999 to 2009, the percentage of RA patients diagnosed between 1999 and 2007 who had biologics dispensations remained steady at 23.3-26.7%. Compared with Caucasian, African Americans were less likely to receive biologics (HR 0.71, 95% CI 0.63 to 0.81). Patients aged 75 and older were less likely to receive biologics than those younger than 45 (HR 0.29, 95% CI 0.23 to 0.36). The time interval between RA diagnosis and treatment with DMARDs and biological agents decreased significantly over time (median: 51 days in 1999-2001 to 28 days in 2006-2007). Conclusions: Methotrexate use increased as it became the preferred first-line agent, while other traditional agents declined. Dispensation of biologics increased significantly, but the proportion of RA patients eventually given biologics stabilised below 30%. A significant shorter time between RA diagnosis and DMARD or biological agent initiation in recent years suggests improvements in quality of care. There were disproportionately lower use of biologics in certain age and ethnic groups, and further studies will be needed to elucidate these observations.

In the present study, using a sample of 367 employees (219 from India and 148 from Bulgaria), we examined whether task interdependence and equity perceptions moderated the relationship between individualism-collectivism orientation and tenure intent. Results indicated that employees with a higher level of collectivism orientation tended to report greater intent to stay with the organization. Further, employees with a higher level of individualism orientation reported greater intent to stay with the organization when task interdependence was lower and equity perceptions were higher. Employees with a higher level of collectivism reported greater intent to stay with the organization when equity perceptions were higher regardless of whether tasks were interdependent or not. Finally, employees, regardless of their individualism or collectivism orientation, reported the lowest tenure intent when tasks were highly interdependent and equity perceptions were low. Implications for theory and practice are discussed. © 2014 Published by Elsevier Inc.

In this work we propose a mechanism which looks at processing the low-level visual information present in video frames and prepares mid-level tracking trajectories of objects of interest within the video. The main component of the proposed framework takes detected objects as inputs and generates their appearance models, maintains them and tracks these individuals within the video. The proposed object tracking algorithm is also capable of detecting the possibility of collision between the object trajectories and resolving it without losing their models. © 2010 Springer-Verlag.

In this paper we are investigating a developmental learning strategy for robotic applications. Two approaches based on Isomap dimensionality reduction and on feature-based learning are investigated. In the training phase, the robot is presented with objects (e.g. squares, circles) and labels regarding their properties (e.g. shape, size, orientation). From these the system learns a representation of each of these properties (concepts) and is then able to recognize them in new images, previously unseen. Based on our experiments, we have concluded that in the Isomap space, given enough samples of objects and their properties, each dimension represents one or a combination of the object properties. The feature-based approach uses a pre-processing technique to extract predefined features from an object image. Our main investigation is concentrated in the Isomap space and related to finding an automated inference mechanism for learning object properties (concepts).

This study seeks to examine the impact of knowledge management strategy on strategic performance in Chinese High Technology firms drawing on the theory of resource-based view. The results from moderated regression analysis show that the knowledge management strategy-performance connection is contingent on both performance-driven strategies, (including reward system and process innovation) and knowledge management-based competencies, such as R&D from past projects, market intelligence, and intraorganizational knowledge sharing. The findings suggest that both performance-driven strategies and knowledge management-based competencies should be considered in the implementation of knowledge management strategy in Chinese High Technology firms. These results have important implications for researchers investigating the effectiveness of high technology firms' adoption of knowledge management strategies in transitional economies as well as practitioners seeking to improve corporate strategic performance. © 2010 Elsevier B.V.

This study aims to investigate how different knowledge-management processes (i.e. knowledge acquisition and dissemination) affect the manufacturers performance in collaborative economic exchanges with their suppliers. Drawing upon the knowledge based view and transaction cost economics, this study proposes that knowledge-management processes are positively related to the performance of the manufacturers in a collaborative buyer-supplier relationship. It also posits that this link is stronger when the levels of supply-chain integration and relational stability are higher rather than lower. The findings of this study show strong support for these propositions. Theoretical and practical contributions of this study are also addressed. © 2013 Taylor & Francis Group, LLC.

Klein (Journal of Business Research 41(3):195-203, 1998) posited that the Web can transform experience goods into search goods (ES shifts). We examine her proposition in three ways. First, we critically assess the background of her proposition in light of the Web evolution in the past decade. Second, we conduct a comparison of past studies that measured the extent of search, experience, and credence (SEC) characteristics of goods. Third, we report the results of an exploratory survey on a set of commonly purchased products to benchmark possible ES shifts against the past studies. Their results indicate that SEC classification changes do not seem significant. © Institute of Information Management, University of St. Gallen 2010.

The purpose of this study is to explore patient factors associated with differences in methotrexate (MTX) dosing and to compare patient factors and MTX-dosing patterns between those who remained on MTX monotherapy and those who were switched or had additional therapy. A retrospective cohort of 7,017 patients with newly diagnosed rheumatoid arthritis (RA) was identified in the United States Department of Veterans Affairs administrative databases between 1 October 1999 and 30 September 2009. Regression analyses were used to study the association of MTX start and maximum dose attained with various patient characteristics and compare differences between groups who had therapeutic change (having switched to or added another anti-rheumatic agent or having steroids increased by 2.5 mg of prednisone or equivalent) with those remaining on MTX monotherapy. Abnormal serum creatinine (>1.5 mg/dL) was associated lower start and peak MTX doses (p<0.01). Older RA patients were less likely to attain peak MTX dose of 15 mg or more (p<0.01). Males and patients 75 and older (compared with <45) had lower risk of therapeutic change (hazard ratio, [HR] 0.80, 95 % confidence interval [CI] 0.72-0.90, and HR 0.42, 95% CI 0.42-0.36-0.50, respectively). Patients who attained higher peak MTX dose had lower risk of therapeutic change compared with those dosed at less than 15 mg/week (HR 0.85, 95% CI 0.77-0.92 for 15 to <20 and HR 0.79, 95% CI 0.72-0.86 for 20 or more). InjectableMTX use conferred lower risk of therapeutic change (HR 0.64, 95% CI 0.52-0.78). Two thirds did not attain a maximum MTX dose of 20 mg/week or more before therapeutic change occurred. Older age and renal insufficiency were barriers to the use of higher MTX maximum dosages. Use of injectable MTX and higher maximum MTX dose were independently associated with higher likelihood to remain on MTX monotherapy. Further studies are needed to explore targeted interventions thatmay optimize MTX dosing to improve success rates of MTX monotherapy. © 2013 Clinical Rheumatology.

Play therapy is commonly used when working with children in counseling. Play therapists work at a developmentally appropriate level to assist children with a variety of mental health and behavioral concerns. Traditionally, play therapy and many counseling methods occur in office settings. We propose that play therapists and other mental health professionals working with children integrate nature and natural settings into their work. The use of nature has been shown to be effective in helping people cope with mental health and physical ailments. In this article, we explore the benefits of the use of nature in mental health and provide a case example of the use of nature and natural settings in counseling. © , Copyright © Taylor & Francis Group, LLC.

This study explores how age and consumers' Web shopping experience influence the search, experience, and credence (SEC) ratings of products and services in online shopping. Using the survey data collected from 549 consumers, we investigated how they perceived the uncertainty of product quality on six search, experience, and credence goods. The ANOVA results show that age and the Web consumers' shopping experience are significant factors. A generation gap is identified for all but one experience good. Web shopping experience is not a significant factor for search goods but is for experience and credence goods. There is an interaction effect between age and Web shopping experience for one credence good. Implications of these results are discussed. © 2010 Springer-Verlag.

Recently, many quantitative or qualitative techniques have been developed to support human resource management (HRM) activities, including Human Resource Information System (HRIS). More importantly, HRIS can include Expert System (ES), Decision Support System (DSS), and Executive Information System (EIS). As DSS and Group Support System (GSS) are able to facilitate human resources (HR) groups to gauge users' opinions, readiness, satisfaction, etc., increase their HRM activity quality, and generate better group collaborations and decision makings with current or planned HRIS services. Consequently, GSS can help HR professionals exploit and make smart use of soft data and act intelligently in their decision making process. This paper presents an in-depth discussion on what GSS is and how it works, which may shed some enlightenments to HR professionals on what grounds GSS can be integrated as part of HRIS and support HRM.

For a superior project result, integrated product development (IPD) project need to have stage-specific management approaches where the front-end structuring supports and strengthens the management of the project and the team during the execution stages. In the current study we focus on relationships on the organizational level variable during the front-end stage of the project, organizational structuring, with a project execution level variable, project team structuring to study the impact on product design glitches and project performance in the concurrent project environment. We hypothesize that managing the overall product development projects with integrated organizational structuring at the front stage and project team structuring during the development and project implementation stages can lead to reduced product glitches which can enhance the overall IPD project performance. We test our hypothetical model using data collected from the US automotive industry. Our data supports all the three proposed hypotheses. Discussion and implication of the empirical results, limitations of the current study, and recommendations for future studies are also provided. © 2011 Elsevier B.V. All Rights Reserved.

This paper examined the impact of knowledge management process competence on corporate growth in the Chinese High Technology industry. The results show that the knowledge management process competence - growth performance connection is contingent on both environmental factor (including market skill & growth and technological turbulence) and organizational system, such as rewards system, project manager skills, and shared vision. The findings suggest that both environmental factor and organizational system should be considered in the improvement of knowledge management process competence in Chinese High Technology industry. These results have important implications for researchers investigating the effectiveness of high technology firms' knowledge management efforts in transitional economies as well as practitioners seeking to improve corporate growth performance. This paper concluded with a discussion of the implications and limitations of the research. © International Journal Of Industrial Engineering.

Background: Women offenders are a growing population in the criminal justice system; most are mothers. A subset of these women have a history of prostitution. Despite more recent research identifying the needs of women offenders who are mothers, those with and without experience in prostitution are still generally represented in the literature as a homogenous group. Methods: This study examined the differences between mothers who indicated that they had engaged in prostitution with those who had not. The data were from a survey of offending mothers in a Midwestern city and was based on 889 respondents. Approximately 20% of the women indicated that they had engaged in prostitution at some point in their lives. Findings: Mothers with histories of prostitution reported more exposure to violence, witnessing crime, living in areas with high drug activity, and having a higher rate of physical and mental health problems. Conclusions: Health care professionals who interact with mothers in the criminal justice system who have histories of prostitution should be careful to assess for a history of trauma and its psychological consequences. Along with increased health care needs, interventions are needed to help these women obtain basic needs such as stable housing outside of high crime and high drug-use areas and to receive targeted psychological services that respond to the unique trauma suffered by this subpopulation of offenders. © 2012 Jacobs Institute of Women's Health.

Grounded in social exchange theory, this study investigates the antecedents and consequences of the improvement of the relationship between a buyer and its major supplier using structure equation modeling. The findings of the analysis show that adaptability and openness and innovation orientation are related to the improvement of a buyer-supplier relationship, which in turn fosters the sharing of tacit and explicit knowledge between exchange partners in a supply chain and enhances learning alliance performance. Theoretical contributions, implications for practitioners, and limitations of this study are also addressed. © 2015.

This study examines the antecedents of strategic alliance formation in manufacturing firms in China, the alliance effect on innovation capability and dyadic quality performance, and how these two organisational capabilities are related to the supply chain performance of Chinese manufacturing enterprises in Shanghai. We perform a series of statistical techniques including logistic regression analysis, multivariate analysis of variance (MANOVA) and multiple regression analysis for assessing the hypothesised relationships. Our findings indicate that relational stability and effective communication are significant antecedent factors influencing strategic alliance formation among Chinese manufacturing enterprises. Such alliance formation is found to benefit innovation capability and dyadic quality performance, which are significant contributors to the supply chain performance of Chinese manufacturers. We provide important theoretical and practical implications on these antecedents and consequences of strategic alliance formation leading to supply chain performance in the Chinese manufacturing context. © 2014 Taylor and Francis.

With the fast development of online communities, it has become critical for firms to understand these communities’ influence on consumers’ consumption experiences. This is especially true in the case of hedonic consumption. The authors used a mixed approach of both quantitative and qualitative studies to analyze consumer online reviews on specific virtual realities (i.e., online video games). This study uncovers three categories of drivers of hedonic consumption in virtual reality, including product attributes, developer strategies, and virtual game community; and three dimensions of outcome, including product-related experience, and behavioral and emotional experiences. The findings also suggest that community involvement intensifies consumers’ hedonic experiences. © Taylor & Francis Group.

Sub-Saharan African countries' economic development is dependent on energy consumption. This paper assesses total energy demand, which is composed of traditional energy (wood fuel) and commercial energy (electricity and petroleum), in the Central, East, South, and West regions of Sub-Saharan Africa. Cross-sectional time series data for 20 countries in 25. years are analyzed, and the results of the study show that wood fuel accounts for 70% of energy consumption, followed by petroleum, with most industrial activities utilizing some form of wood fuel. Regression results suggest that energy demand is inversely related to the price of petroleum and industrial development, but positively related to GDP, population growth rate, and agricultural expansion, and that price elasticity is less than one. The model results also show that there are regional differences in energy demand. In addition, the interaction of population growth rates by regions generates mixed results, and there are regional differences in the use of commercial energy consumption, and GDP growth. The findings of this study suggest that countries must diversify their energy sources and introduce energy-efficient devices and equipment at all levels of the economy to improve GDP growth rate and GDP per capita. © 2010 Elsevier B.V.

The advances in computing power, availability of large- capacity storage devices and research in computer vision have contributed to recent developments in gait recognition. The ease of acquiring human videos by low cost equipments makes gait recognition much easier and less intrusive than other biometric systems. In this paper, a gait recognition system using a space-model-based approach is proposed. The proposed mechanism is able to detect moving object of interest, while track them and analyzing their gait for recognition. The system captures videos of subjects in front a stationary camera. The identification module makes use of the shape and dynamics of the system using HMM. Then it models the gait properties by accepting the feature vectors as input and model the dynamics through state transitions and observation probabilities. The experimental results show that the proposed gait recognition system successfully recognizes humans using their gait. © 2012 Springer-Verlag.

Fundamental to advance video processing such as object tracking, gait recognition and video indexing is the issue of robust background and foreground segmentation. Several methods have been explored regarding this application, but they are either time or memory consuming or not so efficient in segmentation. This paper proposes an accurate and fast foreground detection technique for object tracking in videos with quasi-stationary backgrounds. The background is modeled using a novel real-time kernel density estimations approach based on online histogram learning. It is noted that shadows are classified as part of foreground pixels if further processing on illumination conditions of the foreground regions is not performed. A developed morphological approach to remove shadows from the segmented foreground image is used. The main contribution of the proposed foreground detection approach is its low memory requirements, low processing time, suitability for parallel processing, and accurate segmentation. The technique has been tested on a variety of both indoor and outdoor sequences for segmentation of foreground and background. The data is structured in such a way that it could be processed using multi-core parallel processing architectures. Tests on dual and quad core processors proved the two and four times speed up factors achieved by distributing the system on parallel hardware architectures. A potential direction for the proposed approach is to investigate its performance on a CUDA enabled Graphic Processing Unit (GPU) as parallel processing capabilities are built into our architecture. © 2011 Springer-Verlag.

Online social media, such as Facebook, YouTube, Twitter, and LinkedIn continue to influence and penetrate people's lives from multiple dimensions: communal, commercial, political, religious, and so forth. Motivated by developing a good understanding of such social media user behavior and user satisfaction, the current study develops a theoretical model of social media user satisfaction that incorporates constructs such as value to the user, content, critical mass, capability, timeliness, perceived privacy, ease of use, and format of a social media. The current researchers hypothesize eight positive relationships between the theoretical constructs and user satisfaction in the model. Using a sample size of 398 from the users of Facebook, all eight hypotheses proposed in the model were supported by the data. Discussion of research findings, limitations of the current studies, and direction for future studies are also provided. © 2013 Copyright Taylor and Francis Group, LLC.

Purpose: Given the widespread popularity of social media, such as Twitter, Facebook, Google+, and LinkedIn, theorizing and understanding the user attitude and usage behavior of social media site is fundamental in developing future understandings and deployment of these new technologies. One approach to such studies on drivers of social media usage behavior would be to revisit the technology acceptance model (TAM). The purpose of this paper is to discuss these issues. Design/methodology/approach: Decades of extensive research have focussed on validating the TAM, proposed by Davis (1986), for various types of information systems and communication technologies. TAM forecasts individual adoption and voluntary use of technology. This study examines individual adoption behavior of the most popular social networking site Facebook. The influences on the intention of using social networking based on individual's perceived ease of use (EU), the user's critical mass (CM), social networking site capability (CP), perceived playfulness (PP), trustworthiness (TW), and perceived usefulness (PU) is empirically examined with a primary data set of 398 users of Facebook gathered from a web-based questionnaire survey. Findings: The results demonstrate that the revised social media TAM model proposed in this study supports all the hypotheses of social media usage behavior. The results of this study provide evidence for the importance of additional key variables to TAM in considering user engagement on social media sites and other social-media-related business strategies. Originality/value: Based on our review of existing scientific literature on social media, few empirical studies have been conducted to scientifically evaluate and explain the usage behavior of social media using Facebook. A validated instrument of usage behavior of social media can provide usability experts and practitioners with a validated tool to assess social media acceptance and usage behavior. This can help us gain a better understanding of "who is and who is not using these sites, why and for what purposes" (Boyd and Ellison, 2007). © Emerald Group Publishing Limited.

This study was designed to examine the impact of audio devices, specifically MP3 players used as a take-home assignment, on the fluency rate of beginning readers. Data was collected from the Texas Primary Reading Inventory (TPRI) over 2 years from four first-grade teachers and their students. Growth in fluency scores were calculated and compared between year 1 when students did not use the MP3 players and year 2 when the students used the MP3 players. Teachers also provided information regarding their perceptions of the MP3 players' usage in the classroom. The authors found that the MP3 players made an impact on the growth in fluency scores for the first grade students. Further research is recommended to calculate the impact of the MP3 home reading program for high versus low readers. © Common Ground, Rachel Martinez, Amy Barnhill, All Rights Reserved, Permissions.
