The purpose of this study was to reveal the role of students as agents of change in improving the quality of education in the Batang Kuis sub-district. This study used qualitative methods, observations and interviews as techniques in data collection in this study. The results of this study are that students are agents who have more thoughts to lead to changes that are beneficial to the surrounding community in many ways. As stated in the Tri Dharma of Higher Education which explains about education and teaching which is something that students do, namely studying on campus and off campus and being able to implement the knowledge they have acquired to many people. Second, regarding research and development, subordinate students have an obligation to be able to research any problems that occur in the community, especially in the field of education, so that when students understand the problems that occur in society, students must develop community resources and the potential of the students themselves to implemented for the general public. Finally, community service is that students must be able to provide a positive side such as providing socialization to the community about something new and students can be a mouthpiece for community aspirations.

As participant recruitment and data collection over the Internet have become more common, numerous observers have expressed concern regarding the validity of research conducted in this fashion. One growing method of conducting research over the Internet involves recruiting participants and administering questionnaires over Facebook, the world’s largest social networking service. If Facebook is to be considered a viable platform for social research, it is necessary to demonstrate that Facebook users are sufficiently heterogeneous and that research conducted through Facebook is likely to produce results that can be generalized to a larger population. The present study examines these questions by comparing demographic and personality data collected over Facebook with data collected through a standalone website, and data collected from college undergraduates at two universities. Results indicate that statistically significant differences exist between Facebook data and the comparison data-sets, but since 80% of analyses exhibited partial η2 &lt; .05, such differences are small or practically nonsignificant in magnitude. We conclude that Facebook is a viable research platform, and that recruiting Facebook users for research purposes is a promising avenue that offers numerous advantages over traditional samples.


Technology united with research and development has evolved as a grave differentiator of the agriculture sector in India including production, processing, and agriculture packing and marketing of given crops. Near about 50 percent of the Indian workforce was engaged in the agriculture sector but its share in GDP was only 14 percent, much lower in comparison to former. Though, certain agriculture items showed a steady annual increase in terms of kilograms per hectare. Agriculture transformed significantly over the past few decades but when it comes to investment in research and development there is a lot more which needs to be done. The paper analyzes the role of various research and development institutions in boosting the growth of the agriculture sector that helps in attaining sustainable agriculture development and self-sufficiency in the production process since independence. It also focusesed on the various issues faced by these development institutions. The findings unveiled that since independence a lot more was done to boost the research and development in the agriculture sector at both the center and state levels but a proper implementation of these policies along with transparency could bring more desirable outcomes than were gained at present.

In a high-profile decision of February 6, 2019, the German Federal Cartel Office prohibited Facebook’s data collection policy as an abuse of dominance for infringing its users’ constitutional right to privacy. The case triggered a remarkable interinstitutional dispute between the key players in German competition law. Conflicting rulings by the Düsseldorf Higher Regional Court and the German Federal Court of Justice further illustrate how deeply divided the antitrust community is on the role of competition law in regulating excessive data collection and other novel types of harm caused by dominant digital platforms. This contribution discusses the original prohibition decision, the ensuing court orders, and legislative reform proposals in the broader context of European Union and U.S. competition law.

The role of R&D (research and development) intensity on the effect of knowledge services on the business performance of firms has been discussed by using PLS-SEM and PLS-MGA methods. Research groups were divided into two groups, innovative and non-innovative. Respondents were classified into innovative firms if their R&D intensity was over 3% and vice versa. PLS-SEM and PLS-MGA results were compared for two groups and valuable insights were extracted. For innovative firms, knowledge services seemed to be verified and processed by the decision makers and utilized to achieve their business performance. On the other hand, a large number of non-innovative firms seemed to have a stronger tendency to utilize knowledge services directly for their business without sufficient verification by the decision makers.

There is a prevalent assumption in South Africa that Parliament is guided by the ideals of democracy, accountability, transparency and accessibility. However, there are still gaps and challenges as far as theoversight role of Parliament is concerned, despite the presence of committees that have been established to oversee the executive and relevant structures of government, government activities and public finances. There is widespread maladministration and misuse of government expenditure in government departments. This paper investigates the oversight role of parliamentary committees to determine their relative influence on accountability and democracy in the execution of functions by public functionaries. The aim of the paper is to provide an understanding into inherent problems in the oversight role of Parliament in the democratic dispensation in South Africa, which seems not to have been given serious attention in the academia, considering the pivotal role Parliament plays in the lives of citizens of the country. These oversight committees have selectively held Senior Executives or Ministers accountable for their ineffectiveness, misuse of government expenditure and maladministration. This could be attributed to the fact that oversight in South Africa does not seem to be properly understood and implemented as it should be. Moreover, the influence of the majoritarian authority of the ruling party in committees seems to be colluding with the executive. Failure to take action against cases of omission brings questions on the effectiveness and efficiency of the oversight role of Parliament. The adverse consequence is the delay in the provision of good quality services to poor communities. This paper employed the theoretical approach as a method of data collection. Conclusions have been drawn that the shortcomings of the parliamentary committees compromise accountability and good governance in service delivery.
