A model was developed and used to determine the optimal slaughter weights of pigs with heterogeneous growth raised in a 1,000 head barn and marketed in truckload groups. Explicitly recognizing the heterogeneity of pig weights and marketing the herd over time in truckload batches can...

When the surface temperature of the outdoor coil in an air source heat pump (ASHP) unit is lower than both freezing point of water and the air dew point, frost can be formed and accumulated over outdoor coil surface. Frosting affects the energy efficiency, and periodic defrosting therefore is...

Measures of wealth (‘net’) capital stock (WKS) can be used for measuring economic exposure to natural disasters and thus are essential for disaster risk management in terms of both quick loss estimation during emergency responses and post-disaster planning for recovery and reconstruction....

Literature assessing the quantity and quality of voluntary social and environmental reporting has shown critical reflections regarding the quality and reliability, the (largely) qualitative nature of disclosure with lack of measurability, credibility or comparability, and information being...

Although China is the epicenter of global sourcing and has a vastly different context than the West, almost no key account management (KAM) studies have taken the perspective of Chinese suppliers. Our exploratory multiple-method study uses data gathered from a major Chinese apparel supplier and...

This paper presents evidence for the existence of ‘set-points’ for subjective wellbeing. Our results derive from a 10-year longitudinal study in which subjective wellbeing has been measured using a single question of general life satisfaction. The process of data analysis is driven by logic...

Since its inception, the Strain Theory of Suicide has been tested and supported in a number of empirical studies. This social psychological theory can be employed as a complementary conceptualization to account for suicidal behaviors as well as mental disorders. However, the lack of consistent...

When we think about the loss caused by natural disasters, we generally think about the direct economic loss. Although the direct economic loss is often obvious, the subsequent indirect economic loss can also be quite substantial. This research is a case study about the indirect economic impact...

The importance of panel, or longitudinal, survey data for analyzing subjective wellbeing, and especially its dynamics, is increasingly recognized. Analyses of such data, however, have to deal with two potential problems: (1) non-random attrition; and (2) panel conditioning. The former is a much...
