    2019 Fall.Includes bibliographical references.Supervisor support for employees' nonwork lives positively impacts a variety of outcomes for both employees and organizations. Despite growing evidence for the importance of family-supportive supervisors, the current literature fails to fully capture the supervisor-employee support process by neglecting the role of the employee. To begin addressing this gap, the current study aimed to develop and validate a self-report scale to measure the behaviors that employees perform in order to manage the support they receive from supervisors for nonwork issues. Specifically, the scale draws on support-marshaling literature to capture direct and indirect behaviors that are enacted either to increase support (i.e., approach behaviors) or to decrease nonsupport (i.e., avoid behaviors). Thus, the scale uses 16 items to measure four dimensions of employee support-marshaling: direct-approach, direct-avoid, indirect-approach, and indirect-avoid. Results from an MTurk sample provide initial evidence of reliability (i.e. internal consistency) and validity (i.e., appropriate content, internal structure, and relationships with other variables)

    Building a Semantic Tendering System

    In the new B2B e-commerce arena, applications such as auctions and data exchange are growing rapidly. However, Web content is currently designed for human consumption rather than computer manipulation. This limits the possibility of Web automation. Fortunately, the new development of the Semantic Web that allows Web pages to provide information not only in terms of their content, but also in terms of the properties of that content, can be used for automation. Electronic tendering systems are among the successfully commercial systems that can tremendously benefit from the availability of Semantic Web. This study proposes an e-tendering system that uses the Semantic Web to investigate the automatic negotiation process. The system is built in a P2P environment to simulate a two-player negotiation. It is found that the ontology of semantic information can be used to locate qualified suppliers and precede negotiation. The bargaining power of each party is then determined by the relative magnitude of the negotiators’ respective costs of haggling and the utility that varies with the degree of risk preference. Our experiments showed that applying automatic negotiation strategies to e-tendering system in semantic web can reflect the risk preference of the participants

    Using Association Rule Techniques to Improve Document Retrieval

    Get PDF
    Document management is one of the fastest growing areas of information management. Most conventional approaches assign keywords to documents so that documents can also be retrieved through keywords. The management of data and documents are different. For example, documents have to be appeared in the full contents unlike the selected attributes are retrieved in the data queries. Also, the documents may not relevant even the values of specified attributes are identical. Moreover, documents may be related even they do not have the same keyword value. This study uses an associated knowledge rule algorithm, revised from Apriori algorithm, and classification scheme to discover the relationship between keywords of documents. The proposed algorithm can retrieve related documents without matching specified keywords in users\u27 queries

    Following the evolution of electronic business, collaborative commerce uses information technology to achieve a closer integration and a better management of business relationships among parties including internal personnel, business partners and customers. Recently, market and globalisation competition, customer oriented service strategy and product complexity have pushed enterprises a step further on in collaborative commerce. In brief, collaborative commerce is (1) a collaborative technology – similar to workflow collaboration, (2) a customer-driven technology – similar to a pull-type supply chain, (3) a functionally-integrated technology – similar to concurrent engineering and (4) a businessdriven technology – similar to enterprise resource planning, for cross-organisational integration. The paper will illustrate the technologies and the critical success factors of collaborative commerce adoption

The first chapter of this research work includes the problem, hypothesis, objectives and justification of the present thesis. The second chapter deals with the theoretical framework, which includes the background and the theoretical bases; the same that consists, in turn, of six sections. The first section includes issues related to crime as such. The second section refers to the subjects involved in the crime, based on the forms of criminal intervention, such as authorship and participation. Likewise, the concepts of extraneus and intraneus are included. The third section includes concepts related to the crime of illicit enrichment. The fourth section studies the Criminal Accessibility Principle and the principles that are linked to it. The fifth section refers to the Principle of Incomunicability of circumstances and qualities between authors and participants in the same criminal act. The sixth section focuses on the circumstances and personal qualities of the author that affect or support the criminal liability of the extraneus participant. The third chapter addresses the methodology followed in the present research work. Finally, the fifth chapter includes the conclusions arrived at in this study, having been able to determine that it is possible to sustain the punishability of the extraneus participant in the crime of illicit enrichment, taking into account the incommunicability of circumstances and personal qualities between authors and participants provided in article N ° 26 of the Criminal Code, based on its study and interpretation; Considering that this article would only understand the incommunicability of circumstances and qualities that affect the responsibility of authors to participate in the same criminal act, that is to say, those that attenuate, aggravate or exclude criminal responsibility, being that not being immersed, within This legal precept, the circumstances and qualities that underlie criminal responsibility, these could be communicable from authors to participants in the same punishable act.Tesi

    Augmented reality for learning mathematics: a pilot study with WebXR as an accessible tool

    Get PDF
    One of the concerns in service mathematics courses, such as calculus for engineering, is students’ interest in these studies. Research suggests that engineering undergraduates’ lack of awareness about the importance of mathematics for their study success and for their careers contributes to their low motivation for mathematics. An approach to increasing student motivation is to take advantage of technological tools to provide students with more engaging learning experiences. Recent studies showed that augmented reality (AR) enhances student engagement, motivation, and knowledge retention. However, implementing AR can be challenging since it can be quite costly and technically complex. The current paper describes a case study in which an AR application was designed and developed using WebXR, in the context of a service mathematics course for teaching calculus. The AR content involves drawing of level curves and the visualization of a volcano and the flow of lava to support students’ learning of directional derivatives. A pilot study was conducted to examine engineering undergraduates’ perceptions of using AR for learning mathematics. Results show that students perceived using AR for learning math as enjoyable and motivating. Students reported that AR content adds value to their classes by making the mathematical concepts clearer and helping them apply what they have learned to real life. However, the AR content did not work well on all mobile phones and all versions of web browsers. Lessons learned from the design and development of AR using WebXR as well as recommendations for future studies are discussed in this paper

    Protective actions of des-acylated ghrelin on brain injury and blood-brain barrier disruption after stroke in mice

    The major ghrelin forms, acylated ghrelin and des-acylated ghrelin, are novel gastrointestinal hormones. Moreover, emerging evidence indicates that these peptides may have other functions including neuro- and vaso-protection. Here, we investigated whether post-stroke treatment with acylated ghrelin or des-acylated ghrelin could improve functional and histological endpoints of stroke outcome in mice after transient middle cerebral artery occlusion (tMCAo). We found that des-acylated ghrelin (1 mg/kg) improved neurological and functional performance, reduced infarct and swelling, and decreased apoptosis. In addition, it reduced blood-brain barrier (BBB) disruption in vivo and attenuated the hyper-permeability of mouse cerebral microvascular endothelial cells after oxygen glucose deprivation and reoxygenation (OGD + RO). By contrast, acylated ghrelin (1 mg/kg or 5 mg/kg) had no significant effect on these endpoints of stroke outcome. Next we found that des-acylated ghrelin's vasoprotective actions were associated with increased expression of tight junction proteins (occludin and claudin-5), and decreased cell death. Moreover, it attenuated superoxide production, Nox activity and expression of 3-nitrotyrosine. Collectively, these results demonstrate that post-stroke treatment with des-acylated ghrelin, but not acylated ghrelin, protects against ischaemia/reperfusion-induced brain injury and swelling, and BBB disruption, by reducing oxidative and/or nitrosative damage

    Thalassaemia is a common genetic disorder in Malaysia where the mainstay of supportive treatment is regular blood transfusion accompanied with iron-chelating therapy (ICT). Transfusion dependent thalassaemia (TDT) is defines as patient who requires blood transfusion >100mL/Kg annually. There are about 4500 patients in Malaysia who are suffering from TDT, however limited data is available on economic burden of this disease and also the efficiency of new formulated Deferasirox (Exjade FCT). Therefore, this study is designed to determine the economic burden of disease, cost effectiveness and budget impact of Exjade FCT in Malaysian context. Substudy one is to estimate the total lifetime cost of a TDT patient. Lifetime healthcare cost (TC2) was simulated using Markov model. Lifetime patient and family healthcare expenditure (TC3) was estimated through cross-sectional health survey approach. Survey was conducted using two-stage sampling method in 13 thalassaemia centers covering all regions in Malaysia. Total lifetime TDT cost (TC1) = TC2 + TC3. Substudy two to evaluate the cost effectiveness of Exjade FCT over the long standing gold standard treatment in TDT – Desferrioxamine. Costs and health outcome (quality adjusted life years) was estimated using Markov model. Costs data was extracted from local database and quality of life data was collected using EQ-5D-3L questionnaire among local thalassaemia patient. Lastly, substudy three, budget impact of converting the current oral ICT- Deferasirox dispersible tablet (Exjade DT) to Exjade FCT was evaluated using budget impact model
