Integrate Data

With the growth of cloud services, many companies have begun to persist and make their data available through services such as Data as a Service (DaaS) and Database as a Service (DBaaS). The DaaS model provides on-demand data through an Application Programming Inter- face (API), while DBaaS model provides on-demand database management systems. Different data sources require efforts to integrate data from different models. These model types include unstructured, semi-structured, and structured data. Heterogeneity from DaaS and DBaaS makes it challenging to integrate data from different services. In response to this problem, we developed the Data Join (DJ) method to integrate heterogeneous DaaS and DBaaS sources. DJ was described through canonical models and incorporated into a middleware as a proof-of-concept. A test case and three experiments were performed to validate our DJ method: the first experiment tackles data from DaaS and DBaaS in isolation; the second experiment associates data from different DaaS and DBaaS through one join clause; and the third experiment integrates data from three sources (one DaaS and two DBaaS) based on different data type (relational, NoSQL, and NewSQL) through two join clauses. Our experiments evaluated the viability, functionality, integration, and performance of the DJ method. Results demonstrate that DJ method outperforms most of the related work on selecting and integrating data in a cloud environment.

And Training

The National Certificate (Vocational) (NC(V)) was introduced into South Africa’s system of vocational training to ‘solve problems of poor quality programmes, lack of relevance to the economy, as well as low technical and cognitive skills of TVET [technical and vocational education and training] graduates’. The NC(V) did not, however, meet expectations, partially because of systemic difficulties. This article reports on research conducted among students who studied on the NC(V) Civil and Construction programme in an effort to identify appropriate corrections that could be made by college management. The research project made use of Tinto’s Student Integration Model to identify reasons for both student attrition and student persistence. The study provides information on the predicament facing TVET Civil and Construction students and has broad relevance for practitioners operating in higher and post-school education.

Performance Equation

This article proposes a re-reading of the role of R & D investments in the performance equation when a manifestation of an opportunistic inclination on the part of managers occurs. Often, the manager and the owners express different expectations regarding investment choices in R & D. Although shareholders are looking for performance, the manager sometimes has a tendency to broaden his managerial discretion. The choice of R & D investments could thus reinforce managerial entrenchment. We will demonstrate the moderation exercised by managerial discretion on the R & D / Performance relationship.Our empirical validation will be put to examination against the Tunisian context by deploying various tests. We come to grips with the characteristics of the Tunisian context through an empirical study of 75 companies observed over a 7 -year time lapse, i.e. from 2008 to 2014. The explanatory analysis was an opportunity to highlight the existence of a moderation exercised over the main relationship dealt with.

Abstract This paper studies the effect of globalization on small and medium enterprises (SMEs) performance in Nigeria. The study adopts an ex post-facto type of descriptive research design. In carrying out this study, the secondary statistics data was used. Data was extracted from CBN bulletin on relevant information which depicts globalization and its effect on SMEs performance in Nigeria.A co-integration model was used to investigate the effect of globalization on SMEs performance in Nigeria. To capture the activities of globalization, three proxies were used to capture the activities of globalization; they include interest rate, bank credit and trade openness while on the other hand, output of SMEs to GDP was used to capture SMEs performance covering the period of 1992 to 2014. It was observed that interest rate, bank credit and trade openness do not improve the performance of SMEs output. The overall effect as shown by the F-statistics reveals that the variables considered in this study are not significant in explaining the level of improvement in SMEs output and performance in Nigeria.

Comprehensive Framework

Theories of student attrition based on Tinto’s Student Integration Model are limited in their ability to provide a comprehensive framework to design a computer-adaptive online exit survey. An alternative framework encompassing the overall impressions and experiences of the dropout students during their stay at the institution is used to design the exit survey. This chapter outlines the conceptual and methodological issues surrounding computer-adaptive online exit surveys, and discusses the design, development, and administration of the survey questionnaire.

Student Integration

It is widely recognized that the United States needs to attract and retain more people in science, technology, engineering, and mathematics (STEM) careers. Intensive undergraduate research experiences (UREs) are one of the few strategies shown to improve longitudinal student interest and persistence in STEM-related career pathways; however, less is known about the underlying process linking activities to positive outcomes. The tripartite integration model of social influences (TIMSI) provides a framework for understanding the social influence processes by which students integrate into STEM careers and culture. The current study used a longitudinal design and latent growth curve modeling to examine and predict the development of scientific research career persistence intentions over the course of an intensive summer URE. The latent growth curve analysis showed that student persistence intentions declined and rebounded over the course of the summer. Furthermore, the positive impact of faculty mentor role modeling on growth trajectories was mediated through internalization of science community values. In addition, project ownership was found to buffer students from the typical trend of declining and rebounding persistence intentions. The TIMSI framework illuminates the contextual features and underlying psychological processes that link UREs to student integration into STEM careers and culture.
