Application of replacement theory in dairy cows and its use in disease treatment

A model to simulate the costs and returns of an individual dairy cow over 14 years under various assumptions of genetic potential, health status and management was developed especially to evaluate the effects of diseases that reduce production and reproduction efficiency and to evaluate alternative management interventions. Data were collected from the Food Animal Health Resource Management System (FAHRMX), Today's Electronic Planning (TELPLAN), Today's Electric Farm Accounting (TELFARM) databases and secondary sources at Michigan State University. A case study of cystic ovaries was analysed using the model. The results showed that it is more economical to treat cystic ovaries than not to treat, and treatment with Gonadotropin Releasing Hormone (GNRH) was superior to Human Chrionic Gonadotropin (HCG). Four to five lactations were the optimum for keeping a dairy cow to replacement and it was estimated that there is a loss of US$0.45 per day of extended calving interval (days open beyond the optimal 70 days).     

Preparing for higher inflation: Portfolio solutions using U.S. equities

Investors have always been interested in reducing inflation risk in their portfolios. However, investors face different types of inflation than those measured by the Consumer Price Index (CPI). Moreover, different asset classes can be used to hedge portfolio inflation. In this paper, we show how individual equities can be used to construct equity portfolios sensitive to customized inflation targets. We illustrate portfolios for three types of inflation: US headline CPI, Forbes Cost of Living Extremely Well Index, and the US Medical Care Price Index. We also show how alternative weighting schemes, such as minimum volatility and maximum inflation beta, can be used to construct inflation‐hedged portfolios.     

The role of education in development: A socio‐political perspective

The question of education remains at the core of the development continuum. While education for the good life has been one of the most persistent concerns of men throughout history, in this presentation, it will be argued that education, for the most part, has taken a pedantic and overly managerial approach. It is the major thesis of this paper that education should presuppose a critical and confrontive posture which should continuously examine our political and administrative given in an attempt to explore possibilities for social change. It is a critical approach to re‐evaluate our relationship with the public and their substantive development needs.     

Perception of What the Ethical Climate is and What it Should be: The Role of Gender, Academic Status, and Ethical Education

This study examined ethical attitudes and perceptions of 691 undergraduate seniors and freshmen in a college of business. Gender was found to be correlated to perceptions of "what the ethical climate should be" with female subjects showing significantly more favorable attitude towards ethical behaviors than males. Further, Seniors had a more cynical view of the current ethical climate than freshmen. Freshmen were significantly more likely than seniors to believe that good business ethics is positively related to successful business outcomes. Ethical education was significantly correlated to both perceptions of "current ethical climate" as well as "what the ethical climate should be". Students who had been exposed to ethical issues in a course were more likely to believe both, that ethical behavior is, and should be, positively associated with successful business outcomes.     

E-Commerce Usage and Perception of E-Commerce Issues among Small Firms: Results and Implications from an Empirical Study*

This paper details the results of an empirical study conducted to study the scope and effectiveness of e-commerce deployment in the Commonwealth of Pennsylvania as perceived by small business owners in the state. The methodology and results of this study may be applicable to several other states. In addition to a comprehensive survey of small businesses, a dozen businesses successful in deploying e-commerce were interviewed at great length. The results showed that main parts of an e-commerce infrastructure included (1) flow of information; (2) organizational image; (3) reaction to customer needs; (4) increased sales; and (5) access to new markets. The major reason for businesses to not engage in e-commerce is their perception that it is not strategically important for their business. Results pertaining to regional parameters, sales tax considerations, human resources infrastructure, and Internet security issues as well as policy recommendations are discussed in the paper.     

Establishing a Framework for an Information System

Many decision errors arise out of a failure to understand the nature and structure of the information system that supports policy decisions, public or private. For a information system to be reliable and accurate three subsystems, data collection, inquiry (or analysis) and policy decision, must share the same base of concepts, measurable proxies porn the real world to represent those concepts, and compatible measurement techniques and processing designs in the data used. All information systems must be closely adapted to the specific context of the decisions they are intended to support.
Rapid globalization of markets and the parallel revolution in information technologies and supporting information infrastructure, institutions and human capital are transforming the agri-food sector. The food system is moving away from mass markets driven by the production of standardized commodities toward many smaller, diverse, and customized niche markets driven by consumer preferences for specific food characteristics. Concentration, vertical coordination and integration are growing, particularly in the livestock sector, and especially hogs. Information technologies now permit firms to discover and track consumer preferences while the new biotechnologies make it possible to create the characteristics in products that consumers desire in niche markets. Information has itself become an important commodity.     

A Model for Predicting Outcomes of Sexual Harassment Complaints by Race and Gender

Organizational scholars have studied the impact of sex on sexual harassment outcomes but left unexplored the influences of race. Thus, we use social identity theory to explore the role of race stereotypes and their influences on sexual harassment outcomes. We posit that stereotypes of African-American women tend to be much more negative than those of white women and this serves to marginalize their position both as victims of sexual harassment as well as complainants.

Attributes influencing clothing store choice for an emerging market’s Generation Y Twixter customers

The aim of this paper was to determine the key attributes influencing a sub-segment of Generation Y, the Twixters’ choice of clothing retailers in South Africa, an emerging market. Generation Y has been identified as an important segment particularly for apparel and the Twixter sub-group comprises a third of the segment. Using a positioning theory lens, retailers need to understand the attributes a target market finds important as stores are positioned in consumers’ minds on those attributes. The study therefore sought to determine what these Twixters consider to be important attributes in their clothing store selection. The study comprised two stages; a qualitative stage based on focus group discussion data in which the attributes were determined, discussed and defined, and a quantitative stage, which involved a survey administered to 368 Twixter respondents which determined the relative importance of the attributes to Twixters in their clothing store selection. The results reveal that these Twixters appreciate the price–quality relationship and prefer clothing stores which provide high quality, unique and fashionable merchandise that meets their value for money requirements. The results of the study, although not generalisable, provide noteworthy insight for clothing store and apparel marketers targeting these Generation Y customers.     

An empirical comparison of neural network and logistic regression models

The purpose of this paper is to critically compare a neural network technique with the established statistical technique of logistic regression for modeling decisions for several marketing situations. In our study, these two modeling techniques were compared using data collected on the decisions by supermarket buyers whether to add a new product to their shelves or not. Our analysis shows that although neural networks offer a possible alternative approach, they have both strengths and weaknesses that must be clearly understood.     

Exposure to Ethics Education and the Perception of Linkage between Organizational Ethical Behavior and Business Outcomes

This study focused on the effects of individual characteristics and exposure to ethics education on perceptions of the linkage between organizational ethical practices and business outcomes. Using a stratified sampling approach, 817 students were randomly selected from a population of approximately 1310 business students in an AACSB accredited college of business. Three hundred and twenty eight of the subjects were freshmen, 380 were seniors, and 109 were working managers and professionals enrolled in a night-time MBA program. Overall, the respondents included 438 male students and 379 female students. Exposure to ethics in the curriculum had a significant impact on student perceptions of what should be the ideal linkages between organizational ethical practices and business outcomes. Gender based differences were found with female students having a higher expectation regarding what should be the “ethics practices and business outcomes” link. Exposure to ethics in the curriculum had a positive moderating influence on the gender-based effects on perceptions of ideal ethical climate. The interaction effect showed that exposure to ethical education may have a positive impact on males and allow them to catch up with females in their ethical sensitivities concerning the ideal linkage between organizational ethical behavior and business outcomes. Further, consistent with the literature, the study found that gender differences in ethical attitudes regarding the ideal ethical climate, while significant for undergraduates, appeared to narrow considerably for the working professionals who were part-time MBA students.
