‘Twitter’ in the 21st century has become a useful tool for information gathering, sharing and interactions amongst individuals and for diplomatic negotiations between governments across the world. The potency along the communication lines of twitter lies in its ability to reach a wide and diversified audience quickly and simultaneously. Most intriguing is that individuals through public opinion on twitter hold governments accountable for their actions. With the application of libertarian theory, the prohibition on Twitter in Nigeria is investigated empirically in this study. Drawing on secondary sources of data collection, findings of the study revealed that regardless of the enormous prospects and economic relevance of twitter in Nigeria, the twitter ban is an undemocratic act and an utter infringement on freedom of expression and access to information sharing which constitute fundamental human rights. The study concluded by stating that the Nigerian government should revert the ban on twitter and restore the digital right of Nigerian residents to the platform. The study recommended that democratic institutions should be more consolidated so that the rule of law can be guaranteed. In addition, given that Nigeria is said to be a democratic country, rather than infringing on rights to freedom of speech and expression by control, banning or censoring of social media activities, the Nigerian government can opt for press conferences, press releases and even social media platforms to communicate with a larger crowd on brewing social issues.

In job shops and flow line manufacturing plants, the impact of Cellular Manufacturing System (CMS) with recent advancement in Group Technology (GT) and Automated Manufacturing System (AMS) has resulted in minimizing cost involved in machine maintenance and overhead, machine procurement, machine setup and intra/intercell material movement cost. Meanwhile, the industrialist addressed the problem in deciding the planning horizon to design CMS with respect to the change in customer demand pattern. The Classical CMS failed to capture the fickle in part demand and product mix. In the case of Dynamic CMS (DCMS), the fluctuation is considered by dividing the entire planning horizon into smaller periods. In this paper, a real time data of product mix and product demand were collected from an automobile components manufacturing industry located in SIPCOT Industrial Park, Sriperumbudur to visualize the potential benefits of incorporating DCMS. In this work, existing mathematical model has been used for designing DCMS and it is developed further to convert the model as static environment. Evaluation of the obtained CMS design was done by capturing the exact production parameters of the industry and it is found DCMS resulted in promising cell configuration with minimal overall objective value.

Sustainable Development Goals (SDGs) adopted globally in September 2015 are set to measure development and progress in countries until 2030. China, second to the United States in the global development agenda, by its relations with Africa and Zambia, particularly in the provision of foreign aid currently plays an important role in the development of Zambia’s economy. The large amount of foreign aid provided by China has led to assertions that Zambia is being put in a debt burden, especially as China holds 28 percent of Zambia’s externaldebt. Zambia’s debt burden stands at 60 percent of its Gross Domestic Product (GDP) from 21 percent in 2011 and its debt stock was USD9.37 billion in 2018. Zambia was one of the beneficiaries of debt forgiveness in 2005. The weight of its debt however led to the International Monetary Fund in August 2018, classifying Zambia as a high-risk low-income country having debt distress and inability to service its debt. This study in examining China-Zambia economic relations, explores the impact of Chinese aid on Zambia’s economic development. It investigates the role of this aid in the fulfillment of the SDGs and Zambia’s Vision 2030 of being “a prosperous middle-income nation”. The study adopts Dependency Theory of Raul Prebisch as the theoretical framework of analysis. This explains the economic relations of states and the development of the third world by the interactions between states with inequality being a key feature of these interactions. The paper concludes by providing policy options to salvage the Zambia’s economy and improve on the standard of living of its citizens.
