FACTORS INFLUENCING THE STRATEGIC ALIGNMENT OF INFORMATION TECHNOLOGY WITH BUSINESS IN THE TOURISM INDUSTRY
For the last two decades, information technology (IT) in general, and information
systems (IS) in particular have rapidly advanced in capability and have changed the
way organizations do business. For many organizations, IT spending constitutes one
of the biggest investments each year and as a result, the strategic alignment between
information technology (IT) and business has been a priority for information system
practitioners and business executives. However, the conditions under which IT can be
used for competitive advantage continues to be a major challenge. The objectives of
this thesis were to identify the behavioral, technical and organizational underlying
strategic alignment factors, and to investigate strategic alignment influence of the use
of IT for competitive advantage. The findings of this study further extend the strategic
alignment research stream. This was achieved by developing, empirically testing, and
validating the second-order strategic alignment factor model to investigate the
influence of the strategic alignment between IT and business on the use of IT for
competitive advantage.
Using the survey method, a mail questionnaire has provided 202 respondents of IT
and business executives from the Malaysian service sector (Tour and Travel agents).
The data were analyzed using structural equation modeling (SEM) techniques to
validate the hypothesized second-order strategic alignment factor model.
Confirmatory factor analysis supported the coordination of IT planning with business
planning; communication between IT and managers; human resource skills maturity;
IT infrastructure flexibility; and organizational change adaptability as the underlying
strategic alignment factors. The analysis also supported that strategic alignment
between IT and business to positively influence the use of IT for competitive
advantage. Furthermore, the hypothesized second-order strategic alignment factor
model demonstrated an adequate model fit with the sample data. Hence, the
hypothesis that the proposed second-order factor model fits the data was supported.
The study has made theoretical and practical contributions. First, the theoretical
contribution, the proposed second-order strategic alignment model of this study has
vii
extended the cumulative research of aligning IT strategy with business strategy by
examining how strategic alignment can influence the use of IT for competitive
advantage. Another theoretical contribution is that, strategic alignment is specified as
a second-order construct, derived from the first-order constructs; which are a
coordination of IT and business planning factor; communication between IT and
business managers factor; human resource skills maturity factor; IT infrastructure
flexibility factor; and organizational change adaptability factor. The revised secondorder
strategic alignment factor model not only has acceptable model fit, but also
performs better than the alternative model.
This study has provided a validated and tested research model that will be an
important tool for practitioners and managers to be able to know and assess the
underlying strategic alignment factors, and the influence of strategic alignment of the
use of IT for competitive advantage

Type I diabetes is characterized by an absolute insulin deficiency due to loss of pancreatic â-cell mass by autoimmune aggression. During the progression of the disease proinflammatory cytokines such as IL-1â, TNFá and INFã are secreted by infiltrated and activated T-cells and macrophages which ultimately damage the pancreatic â-cell. However, the signaling mechanisms involved in cytokine-induced damage are only partially understood. Phagocyte-like NADPH oxidase [NOX2] has been shown to play regulatory roles in the metabolic dysfunction of the islet â-cell under the duress of glucolipotoxic conditions and exposure to proinflammatory cytokines. However, the precise mechanisms underlying NOX2 activation by these stimuli remain less understood. Herein, I determined some of the putative cellular mechanisms underlying proinflammatory cytokine-induced metabolic dysfunction and demise of the islet â-cell. Some of the novel findings of my study are: [i] cytokines induce ROS generation and oxidative stress via activation of phagocyte-like NADPH-oxidase [NOX2] such effects are comprised of Rac1 activation, p47phox phosphorylation, and gp91phox expression. I further confirmed that NOX2 is one of the sources for ROS generation under proinflammatory cytokines and glucotoxic conditions as demonstrated by activation of NOX2 activity which is sensitive to apocynin under those conditions; [ii] 2-Bromopalmitate, a classic inhibitor of protein palmitoylation, markedly attenuated cytokine-induced Rac1 activation, NOX2-mediated reactive oxygen species generation and inducible nitric oxide synthase-mediated nitric oxide release indicating that palmitoylation of specific G-proteins [e.g., H-Ras and Rac1] is a key regulatory step involved in cytokine-induced nitrosative and oxidative stress.In addition to oxidative and nitrosative stress, the effect of cytokines in other stress related signaling pathways were also examined. Cytokines activated JNK1/2 and p38 MAPK kinases. They also increased CHOP [C/EBP homologous protein] expression, a marker for endoplasmic reticulum stress, caused caspase-3 activation and FTase and GGTase degradation which leads to defective activation of key G-proteins, defective nuclear membrane assembly and loss in cell viability. Pharmacological inhibitors such as 2-bromopalmitate [inhibitor of palmitoylation], EHop-016 [inhibitor of Vav2-Rac1 axis] and NSC23766 [inhibitor of Tiam1-Rac1 axis] attenuated cytokine-induced JNK1/2 activation implying that Rac1 is upstream to cytokine-induced JNK1/2 activation. Based on the results obtained from my studies, I propose that protein palmitoyl transferase is a novel therapeutic target for the prevention of cytokine-induced metabolic dysfunction of the islet â-cell. As a logical extension of the in vitro studies, a preliminary work has been done in the NOD [non obese diabetic] mice, an animal model of Type I diabetes, and the results showed that both the islets of NOD and control mice express the NOX2 subunits namely, p47phox, p67phox, Rac1 and gp91phox

Evaluating the impact of an intervention to increase uptake of modern contraceptives among adolescent girls (15-19 years) in Nigeria, Ethiopia and Tanzania: the Adolescents 360 quasi-experimental study protocol.
INTRODUCTION: Nigeria, Ethiopia and Tanzania have some of the highest teenage pregnancy rates and lowest rates of modern contraceptive use among adolescents. The transdisciplinary Adolescents 360 (A360) initiative being rolled out across these three countries uses human-centred design to create context-specific multicomponent interventions with the aim of increasing voluntary modern contraceptive use among girls aged 15-19 years. METHODS: The primary objective of the outcome evaluation is to assess the impact of A360 on the modern contraceptive prevalence rate (mCPR) among sexually active girls aged 15-19 years. A360 targets different subpopulations of adolescent girls in the three countries. In Northern Nigeria and Ethiopia, the study population is married girls aged 15-19 years. In Southern Nigeria, the study population is unmarried girls aged 15-19 years. In Tanzania, both married and unmarried girls aged 15-19 years will be included in the study. In all settings, we will use a prepopulation and postpopulation-based cross-sectional survey design. In Nigeria, the study design will also include a comparison group. A one-stage sampling design will be used in Nigeria and Ethiopia. A two-stage sampling design will be used in Tanzania. Questionnaires will be administered face-to-face by female interviewers aged between 18 and 26 years. Study outcomes will be assessed before the start of A360 implementation in late 2017 and approximately 24 months after implementation in late 2019. ETHICS AND DISSEMINATION: Findings of this study will be widely disseminated through workshops, conference presentations, reports, briefings, factsheets and academic publications
