Case Study on Bunker Fuel

Case Study about Bunker Fuel

Introduction: Bunker Fuel is traded in US Dollars world-wide, every major port has its own set of rates and therefore it becomes quite complicated to write a comparative study on an alternative to the US Dollar as a reference currency for bunker fuel. For this reason we have taken the pricing system of WTSA WTSA has a system of bunker fuel pricing and different surcharges (e.g. refrigerated containers) that is clearly explained on their website. Our starting point has prices in US Dollars; these prices represent our starting point. When we turn US Dollars prices into Wocu1prices we introduce an element of volatility that needs to be considered when we look at the results of this case study. The exchange rate USD/Wocu has its own volatility and therefore any Wocu result would be better if we could have a starting point for the Wocu without that element of volatility

Case Study on Bunker Fuel

The availability of data in the WTSA website allows us to use what is essentially a pricing structure aimed at the US Dollar market for a generic trend for bunker fuel prices across different markets. This case study deals with bunker fuel in an oversimplified way; there is no consideration of surcharges and of different pricing for different agreements. However, the principles behind the case we are discussing remain the same whatever the agreement and it is safe to assume that the surcharges (priced in US Dollars themselves) will behave according to similar logic. Although the shipping world is fairly used to use the US Dollar as their main working currency, the clients of shipping lines ultimately pay in their local currency. We shall show how using the Wocu means a reduced volatility and therefore easier and more reliable cost forecasts. Easier and more reliable assessments of future shipping costs may be one of the decisive factors in the decision to enter new markets. Keep reading..

A Case Study on Situations of Fertility Stall in Sub-Saharan Africa

A Case Study about Situations of Fertility Stall in Sub-Saharan Africa

Abstract: A comparative study of fertility trends since 1950 in 30 countries from sub-Saharan Africa revealed several cases of “fertility stall”, that is a change from downward fertility trends to flat- or even slightly rising- trends for some time, usually a few years: Ghana (1998-2003), Kenya (1995-2003), Madagascar in urban areas (1987-1993), Nigeria (1999-2003), Rwanda in rural areas (1999-2005), Tanzania in rural areas (1995-2004). In a first part, the paper presents the statistical evidence of changes in fertility trends. In a second part, the analysis focuses on possible causes of these changes. Fertility stalls were often associated with changes in two proximate determinants (contraceptive use and age at marriage) and in two socio-economic correlates (income and labour force participation). The paper concludes to a variety of situations leading to different causality in the various countries, including one case (Ghana) for which no reasonable explanation could be found from the available data.

Case Study on Fertility Stall

Introduction: The concept of “fertility transition”, defined as the path from natural fertility (high levels) to replacement fertility (low levels), hides a wide variety of local situations: the levels of fertility at onset may differ markedly between countries; fertility may be rising prior to thetransition; the time from peak fertility to replacement fertility may vary from a few decades to a century or more; fertility may level-off around replacement level for a while, then undergo further decline, or fertility decline might continue below replacement level without stopping.Furthermore, an unexpected rise might occur at some time, such as the well documented baby boom in Europe and the United States after the World War II, or fertility decline might stop (fertility stall) for some years during the course of the transition.

A Case Study on Township Health Centers

Case Study about Township Health Centers

Abstract: The Township Health Centers (THCs), which serve China’s rural residents are hospitals with Chinese characteristics. A comparative study of two THCs found that their performance is linked to their successful adaptation to the new economic and institutional context within which they operate. It found that health facility managers need to balance the need to generate revenue with the need to maintain their good reputation with government and the community It identified three major influences on their performance: the pattern of economic incentives, formal and informal rules of behavior and the history and management arrangements of the facility. It concluded that tailoring administrative rules to embrace the market, responding actively to social expectations and proper selection of THC director are all beneficial to THC performance.

Case Study on Township Health Centers

Introduction: Township Health Centers (THCs) are a major provider of health services for China’s rural population. They have faced big challenges during the transition to a market economy associated with major changes in the institutional context within which they operate (Bloom 2005). This paper explores how two successful facilities have balanced the contradictory pressures of expectations by government and communities for certain standards of service and the need to generate revenue. It concludes that future reform initiatives will need to address influences associated with both financial incentives and those associated with the broader social responsibility of health centers. keep reading…

A Case Study on Entertainment Preferences

A Study about Entertainment Preferences: Preference Learning for Cognitive Modeling

Abstract Learning from preferences, which provide means for expressing a subject’s desires, constitutes an important topic in machine learning research. This paper presents a comparative study of four alternative instance preference learning algorithms (both linear and nonlinear). The case study investigated is to learn to predict the expressed entertainment preferences of children when playing physical games built on their personalized playing features (entertainment modeling).

Case Study on Entertainment

Two of the approaches are derived from the literature—the large-margin algorithm (LMA) and preference learning with Gaussian processes—while the remaining two are custom-designed approaches for the problem under investigation: meta-LMA and neuroevolution. Preference learning techniques are combined with feature set selection methods permitting the construction of effective preference models, given suitable individual playing features. The underlying preference model that best reflects children preferences is obtained through neuroevolu tion: 82.22% of cross-validation accuracy in predicting reported entertainment in the main set of game survey experimentation.

Case Study of Formal and Informal Specifications through an Industrial

Case Study about Formal and Informal Specifications through an Industrial

Abstract: In this paper, we discuss a case study in which we have taken a problem from industry and specified it both in B and UML. The object of our case study is the teletext module of a new generation TV. We have discussed our experience, and presented an analysis of both the specifications. We found that, in order to specify a real-time event-driven system, some amount of formality is necessary, which UML does not usually provide. Our industrial collaborators are considering changing their specification process basedon our findings.

Case Study on Formal and Informal

Introduction: In this paper, we perform a comparative study of formal specifications and informal specifications. We have taken a medium size system from a project in industry, and have specified it both formally and informally. For the formal specification, we used B [Abr 96] as the specification language, and for the informal specification, we used UML [Boo 99]. Our most important conclusion is that UML is not sufficient to specify requirements, which may be complex and rigorous in nature. Some amount of formality is necessary to take care of particularly complex issues. Conversely we found that the UML was helpful for visualising the structure of the models compared with a formal specification. keep reading..
