Part/whole percentaging as a useful method in policy/program evaluation

Part/whole percentaging analysis is a simple and meaningful way of evaluating alternative policies, decisions, or other options with multiple goals measured on different dimensions. That kind of analysis involves converting the raw scores of each alternative policy on each goal into a part/whole percentage by summing the raw scores for each goal and dividing each raw score by the total. One can then sum the part/whole percentages across the goals for each policy after assigning at least tentative relative weights to each goal. Part/whole percentages are added for goals that one would like to maximize and are subtracted for goals that one would like to minimize. Where the relative weight of a goal or score is too difficult to determine, one can determine the threshold value at which there is a tie between the tentative first choice and the second choice, and then just determine whether the actual value is above or below the threshold value. The aggregated part/whole percentages for each policy can be used to choose the best policy, the best subset of policies, or to allocate a budget across the policies in proportion to their aggregated part/whole percentages.     

Strategic planning for public relations

Public relations is a key activity for most chairmen of public companies and nationalized industries. It is somewhat suprising therefore how few large companies consider developing an explicit public relations strategy as part of their overall business plan. The reason for this may be partly due to the relatively low regard which senior line managers have for public relations managers and partly because there is a lack of understanding of the nature and use of public relations as a tool of strategic management. The purpose of this article is to discuss why and how business planners should pay more attention to developing explicit public relations strategies for their organizations.     

Understanding Management Performance

Current models of the factors underlying management performance make use of a variety of variables at different levels of analysis. A framework is presented in which variables of three different types are linked together. Using data from a sample (n = 437) of British managers this article explores relationships between personality factors (using the big-five factors), work competencies and managerial performance. Results from the analyses reveal a set of underlying competency factors, which show different patterns of correlation with two facets of performance: current proficiency and promotability. In turn, these factors and the facets of performance show relationships with the big-five personality factors. Current proficiency is more closely related to competencies of organization, specialization and analysis – competencies more likely to be displayed by people who are conscientious and introverted. Promotability is linked more closely to competencies concerning action/motivation, flexibility/sensitivity and communication – competencies more likely to be displayed by people who are extroverted with lower conscientiousness and agreeableness.     

A Meta-Analysis of Children's Hand-to-Mouth Frequency Data for Estimating Nondietary Ingestion Exposure

Because of their mouthing behaviors, children have a higher potential for exposure to available chemicals through the nondietary ingestion route; thus, frequency of hand-to-mouth activity is an important variable for exposure assessments. Such data are limited and difficult to collect. Few published studies report such information, and the studies that have been conducted used different data collection approaches (e.g., videography versus real-time observation), data analysis and reporting methods, ages of children, locations, and even definitions of "mouthing." For this article, hand-to-mouth frequency data were gathered from 9 available studies representing 429 subjects and more than 2,000 hours of behavior observation. A meta-analysis was conducted to study differences in hand-to-mouth frequency based on study, age group, gender, and location (indoor vs. outdoor), to fit variability and uncertainty distributions that can be used in probabilistic exposure assessments, and to identify any data gaps. Results of this analysis indicate that age and location are important for hand-to-mouth frequency, but study and gender are not. As age increases, both indoor and outdoor hand-to-mouth frequencies decrease. Hand-to-mouth behavior is significantly greater indoors than outdoors. For both indoor and outdoor hand-to-mouth frequencies, interpersonal, and intra-personal variability are approximately 60% and approximately 30%, respectively. The variance difference among different studies is much bigger than its mean, indicating that different studies with different methodologies have similar central values. Weibull distributions best fit the observed data for the different variables considered and are presented in this article by study, age group, and location. Average indoor hand-to-mouth behavior ranged from 6.7 to 28.0 contacts/hour, with the lowest value corresponding to the 6 to <11 year olds and the highest value corresponding to the 3 to <6 month olds. Average outdoor hand-to-mouth frequency ranged from 2.9 to 14.5 contacts/hour, with the lowest value corresponding to the 6 to <11 year olds and the highest value corresponding to the 6 to <12 month olds. The analysis highlights the need for additional hand-to-mouth data for the <3 months, 3 to <6 months, and 3 to <6 year age groups using standardized collection and analysis because of lack of data or high uncertainty in available data. This is the first publication to report Weibull distributions as the best fitting distribution for hand-to-mouth frequency; using the best fitting exposure factor distribution will help improve estimates of exposure. The analyses also represent a first comprehensive effort to fit hand-to-mouth frequency variability and uncertainty distributions by indoor/outdoor location and by age groups, using the new standard set of age groups recommended by the U.S. Environmental Protection Agency for assessing childhood exposures. Thus, the data presented in this article can be used to update the U.S. EPA's Child-Specific Exposure Factors Handbook and to improve estimates of nondietary ingestion in probabilistic exposure modeling.     

Strangers in a Strange Land: Shock,Disappointment, and Adjustments Experiences of Expatriates in Central Asia

Increasing globalization is driving an increase in diversity and interaction. A more mobile and international workforce frequently requires that individuals try to understand the norms of their “new” society. This paper provides a preliminary exploration of the types of issues and concerns raised by expatriates working in a new foreign environment. In particular, the paper uses a hybrid survey/interview methodology to identify specific issues raised by expatriates working in Kazakhstan, Central Asia.
