Title: The Optimum Release Height for Javelin Throwers in Proportion to Their Lengths Authors: Abubshara, Jamal; Abdel Fattah, Osama Abstract: This study aimed at identifying the optimum height release for javelin throw proportion to the length of the world champions in the javelin throw event. To achieve this, the researchers used the descriptive correlative approach on a sample of international champions in this event (n=33). Data were collected through some of the previous studies. The study results showed the optimum height release of a javelin throw constitutes a 105.75% proportion to the length of the world champions in this event. The researchers recommend coaches to reconsider determining the height release of the javelin with achieving the optimum velocity and angle release should also be provided. Abbreviations should not be used in the abstract.

Title: Innovations in Human Resource Management: Impact of Social Media Use on Employees' Performance Authors: Alkhateeb, Maan; Abdalla, Rania Abstract: Social media has changed the modes of all aspects of business operations, particularly human resource management practices. Firms are increasingly using social media tools to facilitate information sharing among their employees in an attempt to improve the innovation process and firm performance. It is expected that using new information technologies such as social media will enable the firm to act proficiently on business opportunities and reconfigure human resources by utilizing networks to routinize the business's knowledge and innovation competencies. This study aims to examine how different purposes of social media use to influence employees' level of job performance directly or indirectly through job satisfaction as a mediator. Two purposes are identified: work-related purposes and personal purposes. A closed questions survey tool was used to gather the data from the employees of three leading organizations in the Tulkarm district. Two hundred eighty-two valid questionnaires were analyzed using SPSS and IBM SPSS Amos 24. The findings revealed that the impact of using social media for work purposes on job performance is fully mediated by job satisfaction, while social media use for personal purposes does not influence job performance directly nor indirectly. The current study enriches the available literature by examining social media use from two perspectives: work-related and personal purposes, thus added value to the available literature, particularly in the Palestinian context. Practically, managers could benefit from the work by adopting relevant strategies to guide this use in a way that motivate the employees towards achieving the goals of the organizations. Such as offering reliable internet services which may help in encouraging the employees or even attracting the ones who are not engaged yet in social media to start using it for work purposes, as for personal purposes, specific policies can be adopted to monitor this use within controls. The article recommends organizations to utilize and direct social media use for work purposes towards achieving the goals of the organizations.

Title: Factors affecting buyers’ trust in e-commerce in Palestine Authors: Abdullah, Rania; Saleh, Yahya Abstract: Electronic commerce (e-commerce) is relatively a new concept and research topic in developing countries including Palestine. In this form of commerce, the first impression that users create about an organisation is often based on the organisation’s website’s trustworthiness. This has motivated many researchers to investigate the factors that influence buyers’ trust in such websites. The main purpose of this study is to investigate the potential factors affecting buyers’ trust in e-commerce in Palestine. More specifically, the study embraces a multi-dimensional construct of trust (integrity, benevolence, ability) rather than examining each single dimension of trustworthiness individually. In addition, the effect of independent variables including website design attitudes, reliability, privacy and security attitudes, customer satisfaction and governmental factors on e-commerce’s trust dimensions have been mathematically investigated. To this end, relevant data from a random sample of 354 Palestinian citizens who have experienced the online shopping, or who have interest in online purchasing, were collected. Statistical analyses revealed significant effects of all independent variables except reliability on buyers’ trust in e-commerce in Palestine. Also, four linear regression models relating the independent variables with e-commerce’s trust and its three dimensions (integrity, benevolence, ability) have been built and statistically validated.
