Moving Your Brand Up-Scale: Theory and Suggestive Evidence from Japanese Entry into the U.S. Car Market
EMyeong-Hyeon Cho, Patrick DeGraba
This paper argues that it is difficult for a firm to extend a well-respected brand name from a given quality segment to a higher quality segment. We argue that to enter a higher quality segment, a firm must either introduce a new brand name, or use the existing brand name in the upscale market and cease using it in the lower level market. We present suggestive empirical evidence from Japanese entry into the U.S. luxury car market.
Develop a Hybrid Personnel Scheduling Model
Jiun-Yan Shiau, Chu-Yi Huang
Personnel scheduling is one of the important tasks for human resource management. Due to its complexity, its challenging features, and its practical relevance, personnel scheduling has been heavily researched in the last few decades. Normally, there are three scheduling problems, (1) shift scheduling problem, (2) days-off scheduling problem, and (3) tour scheduling problem. The approach used to resolve those problems are (1) permanence centered planning, (2) fluctuation centered planning, (3) mobility centered planning, and (4) project centered planning. In this study, we reviewed and summarized the present personnel scheduling types and approaches, and then proposed a hybrid personnel-scheduling model to tackle such a complex personnel-scheduling problem. It is a mixed integer-programming model, which consider flexible working hours, deformation working hours, scheduling of mobility, and flexibility of scheduling changes. A simplified real-world case study and data of a Taiwan aviation company are utilized to demonstrate the merits of the proposed model comparing to its original approach.

Students‟ Feedback on their Supervised Work Experience Programme at the Universiti Teknologi Brunei
Ullah Hamid, Kartina Ena, Shamil Ahmad
Feedback is very important for any organization for the sake of improvement. In educational institutions, students‟ feedback helps to comprehend their perception on the quality of education delivered. The paper presents feedback of students attached to various companies during their Supervised Work Experience (SWE) programme. The aim of the study is to assess quality of the SWE programme offered by the Universiti Teknologi Brunei (UTB), Brunei Darussalam. A survey questionnaire is used to know the students‟ feedback on their SWE programme. The assessment takes into account various aspects of SWE programme. Students are found satisfied with majority of the components of their SWE programme. However, weak areas are identified and suggestions are provided for improvement in some components of the programme. Findings of the study provide insights that could assist in improving quality of the future SWE programme resulting in development of curriculum offered by Mechanical Engineering programme at UTB.
Measuring Information Ethics’ Cognition and Behavior: An Empirical Validation
Maryam Nasser AL-Nuaimi, Abdelmajid Bouazza, Maher M. Abu-Hilal
The This study has aimed to construct and validate an empirical multidimensional measure of information ethics’ cognition and behavior. Using different scenarios, and a different sample in a different context, the present study has empirically tested the PAPA conceptual model of the central issues of information ethics as well as the main socio-psychological perspectives such as the theories of Social Cognition, Reasoned Action and Planned Behavior. The findings of this study have provided a piece of evidence in favor of the applicability of the theories of Social Cognition and Planned Behavior to the realm of information ethics. Furthermore, the cognition of information ethics’ issues has positively and significantly predicted the intentions and actual behavior related to the ethical use of Information and Communication Technologies (ICTs)

Lymphocyte Expression of Intracellular Cytokines and Hemeoxygenase-1 in Peripheral Blood of Patients with Atopic Dermatitis
Fadia Mahmoud, Nermina Arifhodzic
It is hypothesized that there is an increase in Th cells expressing IL-4 and IL-10 (Th2 cytokines) in non-lesional skin of atopic dermatitis (AD) patients during the acute phase, and an increase in Th cells expressing TNF-α and IFN-ϒ (Th1 cytokines) in the chronic phase. Hemeoxygenase-1 (HO-1) is a heat shock protein that greatly reduces oxidative tissue damage occurring as a major feature of many inflammatory pathologies. Humans and animals deficient in the enzyme are reported to exhibit chronic and severely dysregulated inflammation. The study evaluates CD4+ T cell expression of intracellular cytokines: Th1 (TNF-α and IFN-ϒ) and Th2 (IL-4 and IL-10); and HO-1 in patients with AD. To provides a preliminary description of correlations between inflammatory cytokines and HO-1, the regulator of oxidative stress. It also suggests a possible therapeutic role for HO-1. The study included 21 patients diagnosed with AD and 12 healthy subjects used as control, age and gender were matched between the AD patients and the healthy subjects. PBMC extracted from the blood of each patient were cultured with PMA/ ionomycin to induce expression of pro-inflammatory biomarkers in CD4+ T cells differentiated to express Th1 or Th2 cytokines and HO-1. Evaluations were performed using FC 500 Beckman Coulter flow cytometer. Higher levels of CD4+ T cell cytokines expression (TNF-α and IFN-ϒ, IL-4 and IL-10) as well as HO-1 was observed in AD patients versus healthy control subjects. A significant direct correlation was observed between CD4+ T cells expressing IFN-ϒ+ and IL-5 (r= 0.651) and between CD4+ T cells expressing TNF-α and HO-1 (r= 0.643). These results show an elevation of T cell cytokine expression of both Th1 and Th2 subtypes and a direct correlation between these two cell populations suggesting a systemic inflammatory profile. Upregulation of the HO-1 is an attempt by the body to limit skin inflammation and it suggests a possible therapeutic role.
