Staffing a Multiskilled Workforce with Varying Levels of Productivity: An Analysis of Cross-training Policies*

Service operations that utilize cross-trained employees face complex workforce staffing decisions that have important implications for both cost and productivity. These decisions are further complicated when cross-trained employees have different productivity levels in multiple work activity categories. A method for policy analysis in such environments can be beneficial in determining low-cost staffing plans with appropriate cross-training configurations. In this paper, we present an integer linear programming model for evaluating cross-training configurations at the policy level. The objective of the model is to minimize workforce staffing costs subject to the satisfaction of minimum labor requirements across a planning horizon of a single work shift. The model was used to evaluate eight cross-training structures (consisting of 36 unique cross-training configurations) across 512 labor requirement patterns. These structures, as well as the labor requirement patterns, were established based on data collected from maintenance operations at a large paper mill in the United States. The results indicate that asymmetric cross-training structures that permit chaining of employee skill classes across work activity categories are particularly useful.

Macro-Economic Factors in Credit Risk Calculations: Including Time-Varying Covariates in Mixture Cure Models

The prediction of the time of default in a credit risk setting via survival analysis needs to take a high censoring rate into account. This rate is because default does not occur for the majority of debtors. Mixture cure models allow the part of the loan population that is unsusceptible to default to be modeled, distinct from time of default for the susceptible population. In this article, we extend the mixture cure model to include time-varying covariates. We illustrate the method via simulations and by incorporating macro-economic factors as predictors for an actual bank dataset.     

Identity Development in an International Transracial Adoptive Family: A 5-Year Case Study

Our case study focused on the adoptive identity development of two female Chinese adoptees over the course of five years (from when they were 7 and 9 until they were 12 and 14 years old, respectively). The study investigated the adoptive parent’s and family identities through six interviews with the adoptive mother, adoptees’ behavioral adjustment reported by the mother, two unstructured observations, and exploration of adoptees’ narratives. The study was guided by a narrative-based framework situated with the cultural socialization approach. Results highlight four central themes: 1) becoming Chinese-Americans; 2) meaning related to adoption is both spoken and unspoken; 3) a we-ness identity, and 4) social-cultural contexts of identity work. Findings demonstrate the incorporation of adoption and the adoptees’ race and culture into the adoptive parent’s and family identities. Findings further illuminate that one’s identity is developed within personal, familial, and social-cultural contexts.     

Cultural Endorsement of Broad Leadership Prototypes and Wealth as Predictors of Corruption

Corruption is a social ill that involves public officials’ misuse of entrusted power, which is a function of sociocultural factors. Rarely, however, do researchers view corruption as a leadership-related problem. In the current research, we conceptualize corruption as a leadership-related problem, and propose three broad leadership prototypes based on social value orientation theory and research. We seek to examine (1) how cultural endorsement of self-serving, prosocial, and individualistic leadership prototypes is related to corruption at the societal level and (2) how wealth moderates the relationship between cultural endorsement of self-serving leadership and corruption. Using archival data of 53 societies, we found that cultural endorsement of self-serving leadership was positively related to corruption, strengthened by wealth. Cultural endorsement of prosocial leadership and individualistic leadership, however, was not significantly related to corruption, and wealth did not moderate either of the relationships. The implications of these findings for theory and future research are discussed.
