A database management capability for Ada
The data requirements of mission critical defense systems have been increasing dramatically. Command and control, intelligence, logistics, and even weapons systems are being required to integrate, process, and share ever increasing volumes of information. To meet this need, systems are now being specified that incorporate data base management subsystems for handling storage and retrieval of information. It is expected that a large number of the next generation of mission critical systems will contain embedded data base management systems. Since the use of Ada has been mandated for most of these systems, it is important to address the issues of providing data base management capabilities that can be closely coupled with Ada. A comprehensive distributed data base management project has been investigated. The key deliverables of this project are three closely related prototype systems implemented in Ada. These three systems are discussed
Addressing the cross-country applicability of the theory of planned behaviour (TPB):A structured review of multi-country TPB studies
The theories of reasoned action and planned behaviour (TRA/TPB) have received substantial research interest from consumer behaviourists. One important area of interest which has not been adequately researched concerns the impact of national culture on the TRA/TPB components and interrelationships. To date, no systematic assessment of the impact of culture on the TRA/TPB model relationships has been undertaken. In order to understand the potential impact of culture on the TRA/TPB model relationships a structured review of TRA/TPB studies is undertaken. Studies that have quantitatively applied the TRA/TPB across at least two countries within a consumption domain since 2000 are reviewed. The authors propose that two of Hofstede�s cultural dimensions, individualism and power distance, may moderate the TRA/TPB relationships. The review highlights that the impact of subjective norm on intention varies most across countries, with the relationship between intention and both attitude and perceived behavioural control operating more similarly across country samples. Further, a systematic assessment of variation in the TRA/TPB model relationships via multilevel modelling shows that only the subjective norm-intention relationship varies across the countries studied. The relationship between subjective norm and intention is found to be influenced by power distance, with a stronger relationship evident in high power distance cultures. This review is the first of its kind and is of significance in addressing the emic versus etic nature of the TRA/TPB. Importantly, the article outlines relevant avenues and recommendations for future cross-national research utilizing the TRA/TPB
Sustainable Consumption Behavior in Sub-Saharan Africa: A Conceptual Framework
This paper develops a conceptual framework for investigating the adoption patterns, inhibitors, and
facilitators ( PIF ) of sustainable consumption in sub-Sahara African ( SSA ) settings. Literature evidence
shows paucity of empirical studies on sustainable consumption from SSA , which partly explains lack
of suitable conceptual framework to guide research in this area. Also, the existing frameworks, which
were developed outside SSA may not be suitable for constructing sustainable consumption behavior
in SSA because of its peculiarities. The key signifi cance of this article is the potential of providing future
researchers in this area with a framework to guide and manage their studies. As a conceptual article,
insight was drawn from a plethora of scholarly articles in the domain of sustainable consumption and
related areas. The framework is built on four key constructs—adoption patterns, inhibitors, facilitators
( PIF ), and intention. As a guide for studies from the SSA , the article includes an empirical section,
which provides preliminary empirical validation for the proposed PIF conceptual framework based on
a pilot test. The result from the pilot study, using structural equation modeling ( SEM ), led to positing the
PIF Sustainable Consumption model, thus giving support for the PIF Conceptual Framework, which
this article puts forward. In addition, the proposed PIF conceptual framework is capable of providing
insight for crafting sustainability-related policies. © 2016 Wiley Periodicals, Inc
