Modeling the growth and policy implications of Global System for Mobile Telecommunication （GSM） in Nigeria

This paper investigated the growth and policy implications of Global System for Mobile Communication in Nigeria. Stochastic economic modeling was used to analyze Nigeria＇s time series data. The models were adjudged reliable before they were used. The components of the model were defined and a prior expectation of the relationship among the variables explained for the purpose of giving the reviewers and users a deep insight into the phenomenon under study. The secondary data used for the study were processed using the E-View for windows electronic packages. The outcome of the empirical and stochastic investigations shows that Global System for Mobile Communication has a positive relationship with output growth in Nigeria. The impact is of a higher magnitude. The usage of Global System for Mobile Telecommunication led to 17 percent rise in the output growth. The findings suggest the need for the Nigerian Communication Commission （NCC） and the federal government of Nigeria to expand tele-density and directly make telephone communications cheap and accessible. To achieve this goal, more licenses should be given to GSM operators in order to allow for healthy competition among them. This will lead to improved quality of services, quality of product and consequently sustain the growth and development of the country.

Using student response systems in the accounting classroom: Strengths,strategies and limitations

A Student Response System (SRS), often referred to as a “clicker,” enables students to individually answer instructor questions on a real-time basis using individual mobile devices, and have the aggregate responses displayed as feedback to the class at the instructor’s discretion. A mobile device can be a proprietary, vendor-specific remote, or a multi-purpose item such as a smartphone or computer. While SRSs have been used in education for some time, we perceive the adoption rate in accounting classes as still being quite low. This paper is a “how to” and “why” guide for accounting faculty who are considering using SRSs, and for experienced users who seek to refine or expand their SRS use.     

《协调制度》与现代化海关发展

当代专利制度改革的理论思潮:劫持论与反向劫持论

专利劫持论者指责专利权人基于劣质专利,选择事后主张,以诉讼相威胁,达到敲竹杠的目的;专利反向劫持论者则强调专利权人的委屈,制造业巨头们无视独立发明人或小企业主的权利主张,恣意免费使用专利技术,专利劫持和反向劫持之间似乎有着不可协调的矛盾。当前专利钓饵不断兴风作浪,将大量发明者推向专利流氓阵营。因此,既要反对专利劫持,又要避免走向反向专利劫持。专利制度改革应该综合两者观点,通过降低专利实施中交易成本、信息不对称和不确定性来维护专利制度的正当性。     

The role of innovative entrepreneurship within Colombian business cycle scenarios: A system dynamics approach

Since the advent of public and private initiatives in Colombia, there has been interest in exploring the possible future pathways of the Colombian business cycle. Based on a foresight analysis, it has been identified on the one hand that it is necessary to achieve greater productivity and competitiveness and on the other hand, collective intentionality towards progress must be encouraged. Using these analyses, new Colombian scenarios are discussed, taking into account intentionality towards entrepreneurship and innovation. Following the entrepreneurship research, it is suggested that innovative entrepreneurial activity is linked to long-term economic growth. Thus, the purpose of this paper is to identify the role of innovative entrepreneurship in Colombian business cycle scenarios using system dynamics (SD) modelling. Here, we approach futures studies, testing dynamic hypotheses concerning development based on societal and socioeconomic integration, in which innovative entrepreneurship is highly relevant. The model, supported by circular flow analysis and Schumpeterian theory, shows how this type of entrepreneurship contributes to sustainable economic growth during the simulation period (2003–2032). To achieve a 6.77% average growth rate (the higher scenario), policies regarding knowledge transfer from specialized foreign individuals, incumbent firms and universities, as well as incentives for entrepreneurial societies and collectivism, are discussed.     

Measuring the effects of transdisciplinary research: the case of a social farming project

Social farming (SF) is an innovative concept belonging to a grey zone occupied by agriculture, social, education and health sectors. It involves various private and public actors who work together to co-create and share new collective knowledge. SF initiatives also involve many policies and tools that need to be reframed in order to facilitate the evaluation of these practices. Research in SF includes the active role of researchers in medium-term initiatives, involving a large number of stakeholders.Thus an evaluation of SF practices is crucial in developing and planning future actions. The complex nature of SF has led to the use of a transdisciplinary approach for the evaluation of its initiatives.This paper explains the transdisciplinary process used in a SF project, describes the nature of the collaborative relationships between researchers and others stakeholders, and examines the factors that inhibit and facilitate this collaboration. The paper highlights the important effects the transdisciplinary approach could have on the future of SF, in terms of network building, the co-production of knowledge, and the development of innovative practices.
