Improving the sustainability of an appropriate technology solution; bone char defluoridation filters in Arusha, Tanzania

High concentrations of fluoride naturally occurring in the ground water in the Arusha region of Tanzania cause dental, skeletal and non-skeletal fluorosis in up to 90% of the region’s population [1]. Symptoms of this incurable but completely preventable disease include brittle, discolored teeth, malformed bones and stiff and swollen joints. The consumption of high fluoride water has also been proven to cause headaches and insomnia [2] and adversely affect the development of children’s intelligence [3, 4]. Despite the fact that this array of symptoms may significantly impact a society’s development and the citizens’ ability to perform work and enjoy a reasonable quality of life, little is offered in the Arusha region in the form of solutions for the poor, those hardest hit by the problem. Multiple defluoridation technologies do exist, yet none are successfully reaching the Tanzanian public. This report takes a closer look at the efforts of one local organization, the Defluoridation Technology Project (DTP), to address the region’s fluorosis problem through the production and dissemination of bone char defluoridation filters, an appropriate technology solution that is proven to work. The goal of this research is to improve the sustainability of DTP’s operations and help them reach a wider range of clients so that they may reduce the occurrence of fluorosis more effectively. This was done first through laboratory testing of current products. Results of this testing show a wide range in uptake capacity across batches of bone char emphasizing the need to modify kiln design in order to produce a more consistent and high quality product. The issue of filter dissemination was addressed through the development of a multi-level, customerfunded business model promoting the availability of filters to Tanzanians of all socioeconomic levels. Central to this model is the recommendation to focus on community managed, institutional sized filters in order to make fluoride free water available to lower income clients and to increase Tanzanian involvement at the management level.

Capital Market Implications of Corporate Disclosure: German Evidence

This paper investigates the relationship between annual report disclosure, market liquidity, and capital cost for firms registered on the Deutsche Börse. Disclosure is comprehensively measured using the innovative Artificial Intelligence Measurement of Disclosure (AIMD). Results show that annual report disclosure enhances market liquidity by changing investors’ expectations and inducing portfolio adjustments. Trading frictions are negatively associated with disclosure. The study provides evidence for a capital-costreduction effect of disclosure based on the analysis of investors’ return requirements and market values. Altogether, no evidence is found that the information processing at the German capital market is structurally different from other markets.

A 13-Year Summary of the ISU Beef Cow Business Record

A 13-year summary of the Iowa State University Extension Service’s Beef Cow Business Record (BCBR) was compiled to show the trends in cost, profit, and production for beef-cow enterprises in Iowa. During these 13 years, 966 yearly records were summarized on herds with an average size of 74.6 cows. Each year-end summary sorts the producers with profits in the top and the bottom thirds of the group so that differences can be analyzed. The average cost to maintain a beef cow from 1982 to 1994 was $370.80. Cost components included in this average total were: feed and pasture, $177.10; operating, $45.40; depreciation, taxes, and insurance, $19.70; labor, $44.90; and capital, $83.70. Producers sorted into the top one-third profit group had 13-year average total cow costs of $309.80, but the bottom onethird profit group averaged $437.10. Economic returns per cow for these same 13 years were: return to capital, labor, and management, $139.50; return to labor and management, $56.20; and net profit, $20.20. Top-profit producers had an average net profit of $126.20 per cow, whereas the least profitable group had an average loss of $107.40. Of this $233.60 difference, $127.30 was due to production cost, and the remaining $106.30 was caused by gross return differences. The average number of pounds of beef produced per cow from 1984 through 1994 was 567. This production was achieved with 2.5 acres of pasture, 3.9 acres of cornstalk grazing, and 4,675 pounds of stored feed per cow unit. Top-profit producers used 673 pounds of stored feed per hundredweight of production, but the least profitable producers used 1,015 pounds. Top-profit producers produced 74 pounds more per cow while using 1,313 pounds less stored feed.

Analyzing PL/1 Legacy Ecosystems: An Experience Report

This paper presents a case study of analyzing a legacy PL/1 ecosystem that has grown for 40 years to support the business needs of a large banking company. In order to support the stakeholders in analyzing it we developed St1-PL/1 — a tool that parses the code for association data and computes structural metrics which it then visualizes using top-down interactive exploration. Before building the tool and after demonstrating it to stakeholders we conducted several interviews to learn about legacy ecosystem analysis requirements. We briefly introduce the tool and then present results of analysing the case study. We show that although the vision for the future is to have an ecosystem architecture in which systems are as decoupled as possible the current state of the ecosystem is still removed from this. We also present some of the lessons learned during our experience discussions with stakeholders which include their interests in automatically assessing the quality of the legacy code.

Relationship between nurse leader emotional intelligence and registered nurse job satisfaction

Aim: To determine the relationship between nurse leader emotional intelligence and registered nurse job satisfaction. ^ Background: Nurse leaders influence the work environments of nurses working at the bedside. Nursing leadership plays an important role in fostering work environments that attract and retain nurses. ^ Methods: A non-experimental, predictive design study conducted in 5 hospitals evaluated relationships between 31 nurse leaders and 799 registered nurses. The nurse leaders were administered the MSCEIT and MBTI. The registered nurses participated in the 2010 NDNQI RN Job Satisfaction Survey. ^ Measurements and Results: The sample population completed two online instruments, the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) and the Myers Brigg Trait Inventory (MBTI). Nurse leader demographic data was collected consisting of age, sex, race, educational level, certification status and years in the profession of nursing. The relationships among characteristics of the nurse leader and staff nurses were examined using regression analysis and stepwise deletion. The results from the MBTI were obtained electronically from CPP. Inc. and the results of MSCEIT were obtained electronically from MHS, Inc. The nurse leader response rate was 46% and the NDNQI RN Job Satisfaction response rate was 62%. The sample of 31 nurse leaders were 65 percent female and 67.7% were White, 12.9% Black, and 19.4% Hispanic. The most prevalent MBTI type was ESTJ (19.35%), followed by ENFJ and ISFJ (9.68% each). The nurse leader sample was primarily extroverts (n=20), sensing (n=18), thinking (n=16) and judging (n=19). The nurse leaders' overall MSCEIT scores ranged from 69 to 111 (implying a range from those who should consider development to competent) with a mean score of 89.84 (consider improvement). The nurse leaders scored highest in the MSCEIT Facilitating subscale with scores ranging from 69 to 121 (consider development to strength) and a mean score of 95.19 (low average score). The overall mean MSCEIT mean scores for the entire sample ranged from 89.90 to 95.19 (consider emotional intelligence improvement to low average score) Overall, staff nurse participants in the NDNQI RN Job Satisfaction Survey were moderately satisfied with the nurse leaders as noted by a mean t score of 55.03 of 60 and this score was consistent with the comparison hospitals that participated in the 2010 NDNQI RN Job Satisfaction Survey (American Nurses Association, 2010). Staff nurses gave nurse leaders a mean score of 4.50 for patient assignments appropriate, and rated a mean score of 4.35 and moderately agreeing to recommend the hospital to a friend. ^ Conclusions: Future research is needed to determine if there is a relationship between nurse leader emotional intelligence ability and registered nurse job satisfaction. Additional research is also needed to determine what to measure in regards to nurse leader emotional intelligence, ability or behavior. Another issue that emerged in the examination of EI is the moderating relationship between the nurse leaders span of control and staff nurse satisfaction on the NDNQI. ^

Business Cycles of Non-mono-cultural Developing Economies: The Case of ASEAN Countries

Based on analyses of actual data, we reveal that many Asian developing economies own economic structural features of "non-mono-cultural economy" and the "large primary good sector", which have not been discussed in developing economies RBC literature. We also examine the input-output tables to develop a model reflecting actual developing economies' structures. Referring to the analyses, we construct RBC models of ASEAN countries. Based on the model, we find that approximately half of GDP volatility is attributable to domestic productivity shocks, and the remaining half is attributable to price shocks.

Trade and Business Cycle Correlations in Asia-Pacific

Recent empirical studies challenge the traditional theory of optimum currency areas by arguing that a monetary union enhances trade and business cycle co-movements among its member countries sufficiently as to obviate the need for national monetary policy. This paper examines the empirical relationship between trade and business cycle correlations among thirteen Asia-Pacific countries, paying particular attention to the structural characteristics of their economies and other issues not explored fully in the literature. According to our result, although trade is relevant to the business cycles of individual countries, the main determinant of their international correlations is not the geographical structure of their trade but what they produce and export --more specifically the extent to which their output and exports are concentrated on electronic products.

Family Business in Mexico: Responses to Human Resource Limitations and Management Succession

Indigenous firms in Mexico, as in most developing countries, take the shape of family businesses. Regardless of size, the most predominant ones are those owned and managed by one or more families or descendent families of the founders. From the point of view of economics and business administration, family business is considered to have variety of limitations when it seeks to grow. One of the serious limitations is concerning human resource, which is revealed at the time of management succession. Big family businesses in Mexico deal with human resource limitations adopting measures such as the education and training of the successors, the establishment of management structure that makes control by the owner family possible and divisions of roles among the owner family members, and between the owner family members and the salaried managers. Institutionalization is a strategy that considerable number of family businesses have adopted in order to undergo the succession process without committing serious errors. Institutionalization is observed in such aspects as the establishment of the requisite condition to be met by the candidate of future successor and the screening by an institution which is independent of the owner family. At present these measures allow for the continuation of family businesses in an extremely competitive environment.

Family Business in Peru: Survival and Expansion under the Liberalization

It is argued that joint stock companies would be transformed from family firms to managerial firms with their development in size and scope. Such managerial firms would have many small shareholders; hence the ownership and management of the firm would be separated. However, in many developing countries including Peru, family businesses, in which families control both ownership and management, still play an important role in the national economy. After the liberalization of economy, which started in Peru in the 1990s, the national market has become more competitive due to the increase in participation of foreign capitals. To secure competitiveness, it is indispensable for family businesses to obtain management resources such as financial, human and technological resources from outside of the families. In order to do so without losing the control over ownership and management, Peruvian family businesses have incorporated companies with distinct characteristics to the extent that they can secure the control over ownership and management inside of their group. While keeping exclusive control of companies in traditional sectors, they actively seek alliance with other families and foreign capitals in competitive sectors. The management of companies with different degrees of control allows them to survive in today's rapidly changing business environment.

Business Cycles and Seasonal Cycles in Bangladesh

The empirical regularities of the Bangladesh business and seasonal cycles are documented in this study. Spectrums, seasonality, volatility, cyclicality, and persistence in the level and variance of macroeconomic variables in Bangladesh are explored using monthly and quarterly macroeconomic series. Most of the features of U.S. and East-Southeast Asian business cycles are common to Bangladeshi business cycles; however, there are some differences. As is seen in the U.S. and European economies, seasonal cycles accentuate the features of business cycles in Bangladesh. To our surprise, the seasonal cycles in Bangladesh embody the features of business cycles in the U.S. and East-Southeast Asian economies more thoroughly than they do the business cycles in Bangladesh.

International real business cycles : a re-visit

It is well known that several quantitative properties of international real business cycle models with are at odds with the data. First, the cross-country correlations are much higher for consumption than for output, while in the data the opposite is true (the BKK puzzle). Second, cross-country correlations of employment and investment are negative, while in the data they are positive. This paper quantitatively shows that preferences with a zero income effect on labor supply help generate a correct cross-country correlation in employment even without any restrictions on financial markets. In a bond economy, a zero income effect in labor supply, combined with time-to-build investment, can generate a positive cross-country correlation in investment, and the BKK puzzle is also resolved when the inter-temporal elasticity of substitution in labor supply is low.

Platforms, network effects and small business dynamics in China : case study of the Shanzhai cell phone industry

This paper seeks to argue the significance of platforms on emerging markets through a case study of the Shanzhai cell phone industry in Shenzhen, China. In this industry, value chains are being driven by both the technology platforms and the market platforms. The former include MTK baseband chipset, and so-called Shared PCBA and Shared Mould. The latter include the North Huaqiang Market and the Purchasing and Money Platform. Technology platforms greatly reduced the technological barriers to entry for independent design houses and system integrators, while market platforms markedly improved their poor marketing and purchasing abilities. Due to factors such as social networks, supporting industries, informality and platform governance, strong network effects have been exhibited in the two types of platforms, which have not only fostered numerous start-ups, but have also led to effective exploitation of emerging markets.

The gap between recognition and the 'compensation business' : the claim against Britain for compensation by Kenya's former Mau Mau fighters

During the first Kibaki administration (2002-2007), a movement by the former Mau Mau fighters demanded recognition for the role that they had played in the achievement of independence. They began to demand, also, monetary compensation for past injustices. Why had it taken over 40 years (from independence in 1963) for the former Mau Mau fighters to initiate this movement? What can be observed as the outcome of their movement? To answer these questions, three different historical currents need to be taken into account. These were, respectively, changing trends in the government of Kenya, progress in historical research into the actual circumstances of colonial control, and a realization, based on mounting experience, that launching a legal action against Britain could turn out to be a lucrative initiative. This paper concludes that, regardless of the actual purpose of the legal case, neither of their objectives was certain to be achieved. Two inescapable realities remain: the doubts cast on the reputation of the government by its decision to lift the Mau Mau‟s outlaw status – a decision that was widely seen as a latter-day example of the „Kikuyu favouritism‟ policy followed by the first Kibaki administration – and the popular interpretation of the involvement of Leigh Day, well known in Kenya ever since the unexploded bombs case for its success in obtaining substantial compensation payments, as a vehicle for squeezing large amounts of money from the British government for the benefit of the Kikuyu people.
