Title: Application of Interval Type-2 Fuzzy Logic System in Short Term Load Forecasting on Special Days
Abstract: This paper presents the application of Interval Type-2 fuzzy logic systems (Interval Type-2 FLS) in short term load forecasting (STLF) on special days, study case in Bali Indonesia. Type-2 FLS is characterized by a concept called footprint of uncertainty (FOU) that provides the extra mathematical dimension that equips Type-2 FLS with the potential to outperform their Type-1 counterparts. While a Type-2 FLS has the capability to model more complex relationships, the output of a Type-2 fuzzy inference engine needs to be type-reduced. Type reduction is used by applying the Karnik-Mendel (KM) iterative algorithm. This type reduction maps the output of Type-2 FSs into Type-1 FSs then the defuzzification with centroid method converts that Type-1 reduced FSs into a number. The proposed method was tested with the actual load data of special days using 4 days peak load before special days and at the time of special day for the year 2002-2006. There are 20 items of special days in Bali that are used to be forecasted in the year 2005 and 2006 respectively. The test results showed an accurate forecasting with the mean average percentage error of 1.0335% and 1.5683% in the year 2005 and 2006 respectively.

Title: Constitution Making and Democratization in Kenya (2000–2005)
Abstract: The article analyses the most intense phase of a process of constitutional review in Kenya that has been ongoing since about 1990: that stage began in 2000 and is, perhaps, not yet completed, there being as yet no new constitution. The article describes the reasons for the review and the process. It offers an account of the role of the media and various sectors of society including women and previously marginalized ethnic groups, in shaping the agenda, the process and the outcome. It argues that although civil society, with much popular support, was prominent in pushing for change, when an official process of review began, the vested interests of government and even of those trusted with the review frustrated a quick outcome, and especially any outcome that meant curtailing the powers of government. Even high levels of popular involvement were unable to guarantee a new constitution against manipulation by government and other vested interests involved in review, including the law and the courts. However, a new constitution may yet emerge, and in any case the process may prove to have made an ineradicable impact on the shape of the nation's politics and the consciousness of the ordinary citizen.

Title: Social isolation and the speed of covid-19 cases: measures to prevent transmission
Abstract: OBJECTIVE To evaluate the social isolation index and the speed of new cases of Covid-19 in Brazil. METHODS Quantitative ecological, documentary, descriptive study using secondary data, comparing the period from March 14 to May 1, 2020, carried out with the 27 Brazilian federative units, characterizing the study population. The data were analyzed through descriptive statistics using the Statistical Package for the Social Sciences-SPSS® software, evaluating the correlation between the social isolation index and the number of new cases of Covid-19, using Pearson's correlation coefficient. RESULTS The increase in Covid-19 cases is exponential. There was a significant, negative correlation regarding the social isolation index and the speed of the number of new cases by Pearson's coefficient, which means that as the first one increases, the second one decreases. CONCLUSION Social isolation measures have significant effects on the rate of coronavirus infection in the population.

Title: The effect of social distance measures on COVID-19 epidemics in Europe: an interrupted time series analysis
Abstract: Abstract Following the introduction of unprecedented “stay-at-home” national policies, the COVID-19 pandemic recently started declining in Europe. Our research aims were to characterize the changepoint in the flow of the COVID-19 epidemic in each European country and to evaluate the association of the level of social distancing with the observed decline in the national epidemics. Interrupted time series analyses were conducted in 28 European countries. Social distance index was calculated based on Google Community Mobility Reports. Changepoints were estimated by threshold regression, national findings were analyzed by Poisson regression, and the effect of social distancing in mixed effects Poisson regression model. Our findings identified the most probable changepoints in 28 European countries. Before changepoint, incidence of new COVID-19 cases grew by 24% per day on average. From the changepoint, this growth rate was reduced to 0.9%, 0.3% increase, and to 0.7% and 1.7% decrease by increasing social distancing quartiles. The beneficial effect of higher social distance quartiles (i.e., turning the increase into decline) was statistically significant for the fourth quartile. Notably, many countries in lower quartiles also achieved a flat epidemic curve. In these countries, other plausible COVID-19 containment measures could contribute to controlling the first wave of the disease. The association of social distance quartiles with viral spread could also be hindered by local bottlenecks in infection control. Our results allow for moderate optimism related to the gradual lifting of social distance measures in the general population, and call for specific attention to the protection of focal micro-societies enriching high-risk elderly subjects, including nursing homes and chronic care facilities.

Title: The impact of the introduction of transgenic crops in Argentinean agriculture
Abstract: Since the early 1990s, Argentinean grain production underwent a dramatic increase in grains production (from 26 million tons in 1988/89 to over 75 million tons in 2002/2003). Several factors contributed to this "revolution," but probably one of the most important was the introduction of new genetic modification (GM) technologies, specifically herbicide-tolerant soybeans. This article analyses this process, reporting on the economic benefits accruing to producers and other participating actors as well as some of the environmental and social impacts that could be associated with the introduction of the new technologies. In doing so, it lends attention to the synergies between GM soybeans and reduced-tillage technologies and also explores some of the institutional factors that shed light on the success of this case, including aspects such as the early availability of a reliable biosafety mechanism and a special intellectual property rights (IPR) situation. In its concluding comments, this article also posts a number of questions about the replicability of the experience and some pending policy issues regarding the future exploitation of GM technologies in Argentina.

Title: Genetically modified crops, corporate pricing strategies, and farmers' adoption: the case of Bt cotton in Argentina
Abstract: This article analyzes adoption and impacts of Bt cotton in Argentina against the background of monopoly pricing. Based on survey data, it is shown that the technology significantly reduces insecticide applications and increases yields; however, these advantages are curbed by the high price charged for genetically modified seeds. Using the contingent valuation method, it is shown that farmers' average willingness to pay is less than half the actual technology price. A lower price would not only increase benefits for growers, but could also multiply company profits, thus, resulting in a Pareto improvement. Implications of the sub-optimal pricing strategy are discussed.

Title: Macroeconomic Convergence in Southern Africa
Abstract: In this paper we aim to answer the following two questions: 1) has the Common Monetary Area in Southern Africa (henceforth CMA) ever been an optimal currency area (OCA)? 2) What are the costs and benefits of the CMA for its participating countries? In order to answer these questions, we carry out a two-step econometric exercise based on the theory of generalised purchasing power parity (G-PPP). The econometric evidence shows that the CMA (but also Botswana as a de facto member) form an OCA given the existence of common long-run trends in their bilateral real exchange rates. Second, we also test that in the case of the CMA and Botswana the smoothness of the operation of the common currency area — measured through the degree of relative price correlation — depends on a variety of factors. These factors signal both the advantages and disadvantages of joining a monetary union. On the one hand, the more open and more similarly diversified the economies are, the higher the benefits they ... Ce Document de travail s'efforce de repondre a deux questions : 1) la zone monetaire commune de l'Afrique australe (Common Monetary Area - CMA) a-t-elle vraiment reussi a devenir une zone monetaire optimale ? 2) quels sont les couts et les avantages de la CMA pour les pays participants ? Nous avons effectue un exercice econometrique en deux etapes base sur la theorie des parites de pouvoir d'achat generalisees. D'apres les resultats econometriques, la CMA (avec le Botswana comme membre de facto) est effectivement une zone monetaire optimale etant donne les evolutions communes sur le long terme de leurs taux de change bilateraux. Nous avons egalement mis en evidence que le bon fonctionnement de l'union monetaire — mesure par le degre de correlation des prix relatifs — depend de plusieurs facteurs. Ces derniers revelent a la fois les couts et les avantages de l'appartenance a une union monetaire. D'un cote, plus les economies sont ouvertes et diversifiees de facon comparable, plus ...

Title: An Empirical Study on the Environmental Kuznets Curve for China’s Carbon Emissions: Based on Provincial Panel Data
Abstract: Abstract Based on the Environmental Kuznets Curve theory, the authors choose provincial panel data of China in 1990–2007 and adopt panel unit root and co-integration testing method to study whether there is Environmental Kuznets Curve for China’s carbon emissions. The research results show that: carbon emissions per capita of the eastern region and the central region of China fit into Environmental Kuznets Curve, but that of the western region does not. On this basis, the authors carry out scenario analysis on the occurrence time of the inflection point of carbon emissions per capita of different regions, and describe a specific time path.

Title: Role of Social Media in Social Change:
An Analysis of Collective Sense Making
During the 2011 Egypt Revolution
Abstract: This study explores the role of social media in social change by analyzing Twitter data collected during the 2011 Egypt Revolution. Particular attention is paid to the notion of collective sense making, which is considered a critical aspect for the emergence of collective action for social change. We suggest that collective sense making through social media can be conceptualized as human-machine collaborative information processing that involves an interplay of signs, Twitter grammar, humans, and social technologies. We focus on the occurrences of hashtags among a high volume of tweets to study the collective sense-making phenomena of milling and keynoting. A quantitative Markov switching analysis is performed to understand how the hashtag frequencies vary over time, suggesting structural changes that depict the two phenomena. We further explore different hashtags through a qualitative content analysis and find that, although many hashtags were used as symbolic anchors to funnel online users' attention to the Egypt Revolution, other hashtags were used as part of tweet sentences to share changing situational information. We suggest that hashtags functioned as a means to collect information and maintain situational awareness during the unstable political situation of the Egypt Revolution.

Title: Identifying Software Project Risks: An International Delphi Study”
Abstract: Advocates of software risk management claim that by identifying and analyzing threats to success (i.e., risks) action can be taken to reduce the chance of failure of a project. The first step in the risk management process is to identify the risk itself, so that appropriate countermeasures can be taken. One problem in this task, however, is that no validated lists are available to help the project manager understand the nature and types of risks typically faced in a software project. This paper represents a first step toward alleviating this problem by developing an authoritative list of common risk factors. We deploy a rigorous data collection method called a "ranking-type" Delphi survey to produce a rank-order list of risk factors. This data collection method is designed to elicit and organize opinions of a panel of experts through iterative, controlled feedback. Three simultaneous surveys were conducted in three different settings: Hong Kong, Finland, and the United States. This was done to broaden our view of the types of risks, rather than relying on the view of a single culture-an aspect that has been ignored in past risk management research. In forming the three panels, we recruited experienced project managers in each country. The paper presents the obtained risk factor list, compares it with other published risk factor lists for completeness and variation, and analyzes common features and differences in risk factor rankings in the three countries. We conclude by discussing implications of our findings for both research and improving risk management practice.

Title: «Overeducation, Undereducation, and the Theory of Career Mobility
Abstract: The theory of career mobility (Sicherman and Galor, Journal of Political Economy, 98(1), 169–92, 1990) claims that wage penalties for overeducated workers are compensated by better promotion prospects. Sicherman (Journal of Labour Economics, 9(2), 101–22, 1991) was able to confirm this theory in an empirical study using panel data. However, the only retest using panel data so far (Robst, Eastern Economic Journal, 21, 539–50, 1995) produced rather ambiguous results. In the present paper, random effects models to analyse relative wage growth are estimated using data from the German Socio-Economic Panel. It is found that overeducated workers in Germany have markedly lower relative wage growth rates than adequately educated workers. The results cast serious doubt on whether the career mobility model is able to explain overeducation in Germany. The plausibility of the results is supported by the finding that overeducated workers have less access to formal and informal on-the-job training, which is usually found to be positively correlated with wage growth even when controlling for selectivity effects (Pischke, Journal of Population Economics, 14, 523–48, 2001).

Title: Energy consumption, employment and causality in Japan: a multivariate approach
Abstract: Using Hsiao's version of Granger causality and cointegration, this study finds that employment (EP), energy consumption (EC), Real GNP (RGNP) and capital are not cointegrated. EC is found to negatively cause EP whereas EP and RNGP are found to directly cause EC. It is also found that capital negatively Granger-causes EP while RGNP and EP are found to strongly influence EC. The findings of this study seem to suggest that a policy of energy conservation may not be detrimental to a country such as Japan. In addition, the finding that energy and capital are substitutes implies that energy conservation will promote capital formation, given output constant.

Title: Design of a Resilient Information System   for Disaster Response
Abstract: The devastating 2011 Great East Japan Earthquake made people aware of the importance of Information and Communication Technology (ICT) for sustaining life during and soon after a disaster. The difficulty in recovering information systems, because of the failure of ICT, hindered all recovery processes. The paper explores ways to make information systems resilient in disaster situations. Resilience is defined as quickly regaining essential capabilities to perform critical post disaster missions and to smoothly return to fully stable operations thereafter. From case studies and the literature, we propose that a frugal IS design that allows creative responses will make information systems resilient in disaster situations. A three-stage model based on a chronological sequence was employed in structuring the proposed design principles.

Title: Electricity consumption, income, foreign direct investment, and population in Malaysia: new evidence from multivariate framework analysis
Abstract: Purpose - This study attempts to re-investigate the electricity consumption function for Malaysia through the cointegration and causality analyses over the period 1970 to 2005. Design/methodology/approach - The study employed the bounds-testing procedure for cointegration to examine the potential long-run relationship, while an autoregressive distributed lag model is used to derive the short- and long-run coefficients. The Granger causality test is applied to determine the causality direction between electricity consumption and its determinants. Findings - New evidence is found in this study: first, electricity consumption, income, foreign direct investment, and population in Malaysia are cointegrated. Second, the influx of foreign direct investment and population growth are positively related to electricity consumption in Malaysia and the Granger causality evidence indicates that electricity consumption, income, and foreign direct investment are of bilateral causality. Originality/value - The estimated multivariate electricity consumption function for Malaysia implies that Malaysia is an energy-dependent country; thus energy-saving policies may have an inverse effect on current and also future economic development in Malaysia.

Title: Potential Benefits of Agricultural Biotechnology: An Example from the Mexican Potato Sector
Abstract: The study analyzes ex ante the socioeconomic effects of transgenic virus resistance technology for potatoes in Mexico. All groups of potato growers could significantly gain from the transgenic varieties to be introduced, and the technology could even improve income distribution. Nonetheless, public support is needed to fully harness this potential. Different policy alternatives are tested within scenario calculations in order to supply information on how to optimize the technological outcome, both from an efficiency and an equity perspective. Transgenic disease resistance is a promising technology for developing countries. Providing these countries with better access to biotechnology should be given higher political priority.

Title: Mobility-based clustering protocol for wireless sensor networks with mobile nodes
Abstract: In this study, the authors propose a mobility-based clustering (MBC) protocol for wireless sensor networks with mobile nodes. In the proposed clustering protocol, a sensor node elects itself as a cluster-head based on its residual energy and mobility. A non-cluster-head node aims at its link stability with a cluster head during clustering according to the estimated connection time. Each non-cluster-head node is allocated a timeslot for data transmission in ascending order in a time division multiple address (TDMA) schedule based on the estimated connection time. In the steady-state phase, a sensor node transmits its sensed data in its timeslot and broadcasts a joint request message to join in a new cluster and avoid more packet loss when it has lost or is going to lose its connection with its cluster head. Simulation results show that the MBC protocol can reduce the packet loss by 25% compared with the cluster-based routing (CBR) protocol and 50% compared with the low-energy adaptive clustering hierarchy-mobile (LEACH-mobile) protocol. Moreover, it outperforms both the CBR protocol and the LEACH-mobile protocol in terms of average energy consumption and average control overhead, and can better adapt to a highly mobile environment.

Title: Co-integration and causality relationship between energy consumption and economic growth: further empirical evidence for Nigeria
Abstract: Abstract The Paper re ‐ examined co‐integration and causality relationship between energy consumption and economic growth for Nigeria using data covering the period 1970 to 2005. Unlike previous related study for Nigeria, different proxies of energy consumption (electricity demand, domestic crude oil consumption and gas utilization) were used for the estimation. It also included government activities proxied by health expenditure and monetary policy proxied by broad money supply though; emphasis was on energy consumption. Using the Johansen co‐integration technique, it was found that there existed a long run relationship among the series. It was also found that all the variables used for the study were I(1). Furthermore, unidirectional causality was established between electricity consumption and economic growth, domestic crude oil production and economic growth as well as between gas utilization and economic growth in Nigeria. While causality runs from electricity consumption to economic growth as well a...
