This exploratory study examines factors which are expected to be significantly correlated with Trust and Distrust in social commerce (SC). Unlike other studies, Trust and Distrust are explored as separate dimensions rather than extreme values of a single dimension. Using data from a sample of 662 SC users all of the factors were found to be significantly correlated with Trust or Distrust and the results were the same for males and females. The findings support the idea that Trust and Distrust may be conceptualized as different dimensions. New findings related mainly to correlations: with Distrust, involving cultural characteristics and personality traits, and between Trust and Age, Education, and SC Experience. Practical implications identified factors that may be influenced by practitioners to decrease distrust or increase trust as well as factors that define profiles of consumers with different levels of trust and distrust.

Personal characteristics were studied as the determinants of forwarding online content behavior using data collected from a sample of 386 individuals. Personal characteristics included: gender; age; experience with online information services; level of consumption of online content; and the 16 personality traits. With the exception of gender and 15 of the personality traits, these personal characteristics significantly influenced forwarding behavior with no significant differences between males and females. Although not acting as significant determinants for forwarding behavior these 15 personality traits enabled the development of profiles for individuals with characteristics that did significantly influence forwarding behavior. These results represent new findings with respect to forwarding behavior and provide important theoretical and practical insights.

Cultural characteristics of an online virtual community (VC) are compared with cultural characteristics of Thai society (TS). Cultural characteristics are analyzed using Hofstede's dimensions and data from a sample of 369 Thai citizens who are active members of a VC. Also, associations between cultural characteristics and personal characteristics (gender, age, education, VC experience, and work position) were examined in both contexts. The findings indicate (1) individualism, masculinity, and indulgence are more evident in TS than in a VC; (2) in a VC, there were no significant differences between males and females. In TS, males placed more emphases on power distance and uncertainty avoidance and less on long term orientation; and (3) in a VC, only age and experience were associated significantly with cultural dimensions. In TS, work position was the only characteristic that was not associated significantly with cultural dimensions. Practical implications of the findings are discussed.

This study examined the importance assigned by Human Resource personnel to the personality traits of Information Technology officers. The extent to which these traits were evident among Information Technology officers was determined and compared to their level of importance among Human Resource personnel. The well-known 16 Personality Factors model was used and data was collected by questionnaire from 84 Information Technology officers working at operational levels in organizations and 64 Human Resource personnel with experience in the recruitment of Information Technology officers. For most of the traits the findings showed reasonable agreement between the level of importance of the traits according to the Human Resource personnel and the extent to which traits were evident among the Information Technology officers. However, there were differences with respect to the four traits Friendliness, Introversion, Sensitivity, and Intellect and the practical implications of these findings are discussed.

The purpose of this study is to explore expectations in information technology skills for organizations in Vietnam, a developing country in South East Asia. Previous research in Vietnam has mainly focused on information technology adoption; this study offers an insight into the demands of information technology skills in Vietnam. A theoretical framework consisting of five domains of expertise is used to examine the nature and structure of information technology profession in Vietnam. Results from the study show that there is an anticipated increase in demand for information technology professionals who possess deep skills in a broad scope of roles and experience both in information technology and other business domains. Technical skills in the technology infrastructure and services domain in combination with strong communication and problem solving qualities are highly valued by Vietnamese employers.

A theoretical model of information technology (IT) project management was formulated based on the results of previous studies incorporating transactional and transformational leadership styles, team diversity, and team culture as determinants of team processes and project outcomes. The study addresses the lack of previous studies of IT projects and is concerned with infrastructure and software projects conducted in cross-functional environments with co-located teams in the context of Thailand. The model was tested and developed to a final model using data collected from a sample of 219 professionals with experience in IT projects in Thailand. The results confirmed several reported effects of leadership styles, team diversity, and culture on team cooperation, cohesion, and conflict and their subsequent effects on performance and psychosocial project outcomes. The findings highlighted results not commonly reported in previous studies of IT project management concerning the role of dominant cultural characteristics of Thai society at the level project teams as well as important direct effects of leadership styles and aspects of team diversity on performance and psychosocial outcomes. Based on the findings practical recommendations for improving IT project outcomes are presented.

The study compared ICT professional requirements in organizations in Thailand with ICT bachelor degree curricular offered in universities in Thailand using a theoretical framework with three related components: domains of expertise; the scope of the professional’s knowledge, skills, and experience; and specific skills associated with the domains of expertise. Data was collected by questionnaire from 166 medium to large sized organizations and 42 universities which offered in total 78 ICT related bachelor degree programs. The findings showed that, although there was a reasonable degree of alignment between the importance of skills in the organizations and the ICT curricular, the ICT programs were not addressing adequately the needs of organizations for a range of skills related to understanding organizations and their functions, ICT management activities, and especially the management of ICT physical and financial resources. On the other hand, ICT programs placed more emphasis than the organizations on skills concerned with systems development methodologies for the complete development of applications/systems, CASE tools, programming and coding, database design, technical expertise with object relational and object oriented databases, and multimedia applications. Previous studies of this kind conducted in Thailand were not found and the findings are expected to be of value and interest to those responsible for national ICT policy and especially ICT education and training.

This exploratory study investigates the adoption and use of information and communication technologies in Myanmar by examining the nature and structure of the information technology profession. The investigation is based on a theoretical framework consisting of three components: domains of information technology professional expertise; the scope of the information technology professional’s knowledge, skills and experience; and specific knowledge and skills associated with the domains of professional expertise. The findings show that specialist skills in systems development, database, network and communications are important. This paper also provides insights that are not found in current literature which investigates information technology skills in Myanmar.

This exploratory study compares the adoption and use of ICT in the developing nations of Vietnam and Thailand by examining the nature and structure of the IT profession in medium to large size organizations. A theoretical framework is used with three related components: domains of IT professional expertise; the scope of the IT professional’s knowledge, skills, and experience; and specific knowledge and skills associated with the domains of professional expertise. The findings provide insights that are not found in existing reports which address ICT issues at a national rather than an organizational level. In particular, findings concerned with the first two components of the framework for both nations are compared to predictions about the adoption and use of ICT in organizations in technologically developed nations.

Predictions about changes over the period 2005 to 2010 in the nature and structure of the IT profession in organizations operating in developed nations were tested for organizations operating in eight different organizational sectors in Thailand. Data collected in 2006 and 2011 from organizations in Thailand was used to test the predictions and to identify similarities and differences among the sectors with respect to the importance of specific knowledge and skills associated with each part of the predicted structure. The findings provide theoretical and practical insights into the development of the nature and structure of the IT profession in Thailand over the past five years and the relative importance of IT professional skills in each organizational sector.

The study determines and compares the development plans of 72 medium to large sized organizations representing 7 organizational sectors in terms of the relative and changing importance assigned to a range of technologies, professional activities, and IT knowledge/skills and assesses the alignment of these development plans with national policy objectives.

The explosive growth in the usage of IEEE 802.11 network has resulted in dense deployments in diverse environments. Most recently, the IEEE working group has triggered the IEEE 802.11ax project, which aims to amend the current IEEE 802.11 standard to improve efficiency of dense WLANs. In this paper, we evaluate the Dynamic Sensitivity Control (DSC) Algorithm proposed for IEEE 802.11ax. This algorithm dynamically adjusts the Carrier Sense Threshold (CST) based on the average received signal strength. We show that the aggregate throughput of a dense network utilizing DSC is considerably improved (i.e. up to 20%) when compared with the IEEE 802.11 legacy network.

Small satellites flying in clusters require periodic “stationkeeping” to keep them in place. The required impulse is very small – the goal is not to keep the individual satellites in rigid formation, but only to keep them in well-defined orbitals with respect to one another. The necessary impulse, therefore, is only the amount needed to overcome the difference in drag between the most-affected and the least-affected satellites in the cluster. Estimates are that the differential drag can be overcome by providing ~1 mNsec (micro-Newton second) to ~1 mN sec (milli-Newton second) every 10 to 100 seconds throughout each satellite’s mission. The system we are developing will do that. The thrusters have very low power and energy thresholds for ignition (~10 mWatts, ~100 μJoules), and no moving parts so they are expected to be highly reliable. A single thruster array contains a quarter of a million separate thrusters.

The article of record as published may be found at http://dx.doi.org/10.1021/jo00909a001 Bromine atoms, generated by irradiation by a mercury lamp bearing a filter to assure that only wavelengths >310 nm passed, were permitted to react with a series of 1,2-diarylcyclopropanes in carbon tetrachloride solution. The major product in all cases (>80%) was the 1,3-dibromo-1,3-diarylpropane. Kinetic data at approximately 10ˉ³M gave a rate expression dBr₂/dt = -k(cyclopropane)(bromine)¹′². A Hammett treatment of the data gave p = -0.5 for both the cis series and the trans series. Synthesis of several possible minor products and their comparison with the reaction mixture by TLC is reported. Possible reactions such as induced isomerization are thus eliminated from consideration. Bureau of Naval Personnel Office of Naval Research
