Combining Quantitative Risk Assessment of Human Health,Food Waste,and Energy Consumption: The Next Step in the Development of the Food Cold Chain?

The preservation of perishable food via refrigeration in the supply chain is essential to extend shelf life and provide consumers with safe food. However, electricity consumed in refrigeration processes has an economical and an environmental impact. This study focuses on the cold chain of cooked ham, including transport, cold room in supermarket, display cabinet, transport by consumer, and domestic refrigerator, and aims to predict the risk for human health associated with Listeria monocytogenes, the amount of food wasted due to the growth of spoilage bacteria, and the electrical consumption to maintain product temperature through the cold chain. A set of eight intervention actions were tested to evaluate their impact on the three criteria. Results show that the modification of the thermostat of the domestic refrigerator has a high impact on food safety and food waste and a limited impact on the electrical consumption. Inversely, the modification of the airflow rate in the display cabinet has a high impact on electrical consumption and a limited impact on food safety and food waste. A cost–benefit analysis approach and two multicriteria decision analysis methods were used to rank the intervention actions. These three methodologies show that setting the thermostat of the domestic refrigerator to 4 °C presents the best compromise between the three criteria. The impact of decisionmaker preferences (criteria weight) and limitations of these three approaches are discussed. The approaches proposed by this study may be useful in decision making to evaluate global impact of intervention actions in issues involving conflicting outputs.     

Testing of the Function Focused Environment Assessment and the Function Focused Policy Assessment in Assisted Living

This study tested two new instruments, the Function Focused Environment Assessment (FF-EA) and the Function Focused Policy Assessment (FF-PA). The measures were developed for clinical evaluation of assisted living (AL) settings to help optimize function and physical activity among residents. In total, 106 AL settings and 242 residents were included. There was evidence of item reliability (0.92) and interrater reliability (kappa =0.40, p = .015; agreement 85%) of FF-EA and item reliability (0.89) and interrater reliability (kappa =0.48, p = .001, agreement 82%) of the FF-PA, and support for validity of both measures based on INFIT and OUTFIT statistics and hypothesis testing.     

Personal Network Characteristics as Predictors of Change in Obesity Risk Behaviors in Early Adolescence

The potential for peers to influence obesity risk behavior increases in adolescence, yet there are knowledge gaps of how behaviors are modified in response to peers over time. This study examined how personal friendship network characteristics were associated with obesity‐related behaviors from late childhood to early adolescence. Two waves of friendship, physical activity, screen time, and dietary recall data were collected from 11‐ to 13‐year‐old students (99% retention) in Australia (n = 308) over a five‐ to eight‐month period. Regression models identified friendship network characteristics that predicted later health behaviors which varied by gender and behavior type, such as the number of friends positively associated with physical activity intensity (males) and screen time (females). The need for considering context to influence behavior change is discussed.

Manifest destiny,American exceptionalism,and the city on a hill seen through Winthrop,O'Sullivan,and Bush: Opportunities for religious peacebuilding

A dominant theme in the story of the American, city-on-a-hill experience is manifest destiny, a term literally expressing a sense of a rightful, westward expansion across the continent in the late 19^th century, but more broadly expressing a general entitlement granted, it is often understood, divinely to an exceptional United States of America. The origins, the political-versus-religious undergirding, and the implications of manifest destiny are widely discussed in the literature. Here I focus on three primary texts by John Winthrop, John O'Sullivan, and George W. Bush to argue that, even though Winthrop's and his fellow Puritan immigrants' understanding of their role in the new land was a far cry from that of O'Sullivan—who coined the term “manifest destiny” – the seeds of manifest destiny were brought with these first immigrants to the Massachusetts Bay Colony, later sprouting and blossoming in O'Sullivan's coining, and eventually bearing some of its many fruits Bush's foreign policy. Finally, I will discuss the sociological and other implications of the divine endorsement of such ideas.     

The gender gap on public opinion towards genetically modified foods

Ever since genetically modified (GM) foods were introduced into the food supply in the 1990s they have provoked debate and concern. The number of GM foods approved by the U.S. Food and Drug Administration and offered on supermarket shelves has steadily grown at the same time that public wariness about the safety of GM foods has increased. Studies within the scientific literature show a strikingly large gender gap in attitudes towards GM foods with women consistently more skeptical than men. However, there have been few efforts to understand the determinants of the gender gap on GM foods within the political science literature. This study employs a 2014 Pew Research Center survey on science issues to test several possible explanations for the gender gap in attitudes towards GM foods rooted in the different life experiences of women and men. The results show that while being a parent predicts more skeptical views about genetically modified foods overall it does not explain the gender gap in attitudes. In contrast, knowledge about science and having confidence in science do play a significant role in mediating the gender gap. By exploring the robust and pervasive gender gap on the issue of GM foods, this study sheds light on the fundamentally different ways men and women approach political issues.     

An Interactive Forecasting System

Time sharing computer configurations have introduced a new dimension in applying statistical and mathematical models to sequential decision problems. When the outcome of one step in the process influences subsequent decisions, then an interactive time-sharing system is of great help. Since the forecasting function involves such a sequential process, it can be handled particularly well with an appropriate time-shared computer system. This paper describes such as system which allows the user to do preliminary analysis of his data to identify the forecasting technique or class of techniques most appropriate for his situation and to apply those in developing a forecast. This interactive forecasting system has met with excellent success both in teaching the fundamentals of forecasting for business decision making and in actually applying those techniques in management situations.
