Identifying design criteria for urban system ‘last-mile’ solutions – a multi-stakeholder perspective

Abstract

This study presents a novel approach to design and evaluate ‘last-mile’ solutions – encompassing the social and economic perspectives of key stakeholders. While urban system initiatives have been implemented in practice, theoretical gaps remain at the operational design level. A theoretical framework is developed, based on design criteria identified from a critical synthesis of supply chain and operations management literature, and ‘operationalised’ using an in-depth case study demonstrating implementation of a Consumer Choice Portal-Package Consolidation Centre solution, within a densely populated urban geography. Findings suggest that there is a need to re-define the role of institutional actors beyond that of the traditional governance task, to one of being able to facilitate performance outcomes. Similarly, industrial efficiency dimensions need to be reorientated to include consumer participation, social considerations and multi-stakeholder service outcomes. Finally, implications for operations theory and practising managers in city logistics are highlighted, with suggested directions for future research.     

Using the integrative model of behavioral prediction to understand college students’ STI testing beliefs,intentions, and behaviors

ABSTRACT

Objectives: To identify salient behavioral determinants related to STI testing among college students by testing a model based on the integrative model of behavioral (IMBP) prediction. Participants: 265 undergraduate students from a large university in the Southeastern US. Methods:Formative and survey research to test an IMBP-based model that explores the relationships between determinants and STI testing intention and behavior. Results: of path analyses supported a model in which attitudinal beliefs predicted intention and intention predicted behavior. Normative beliefs and behavioral control beliefs were not significant in the model; however, select individual normative and control beliefs were significantly correlated with intention and behavior. Conclusions: Attitudinal beliefs are the strongest predictor of STI testing intention and behavior. Future efforts to increase STI testing rates should identify and target salient attitudinal beliefs.     

Increasing Child Serving Professionals’ Awareness and Understanding of the Commercial Sexual Exploitation of Children

ABSTRACT

Child serving professionals need increased understanding of the identification and therapeutic needs of child victims of commercial sexual exploitation. This study evaluated the effectiveness of a training program aimed to increase awareness of commercial sexual exploitation of children (CSEC) among professionals likely to encounter victims in their work. Professionals’ (N = 227) knowledge level was examined prior to the training, immediately thereafter, and in a 6–12 month follow-up. Despite professional position or years of experience, participants had similar levels of CSEC knowledge before the training and all showed a significant improvement in their knowledge after the training. However, follow-up testing on a smaller subsample demonstrated that knowledge gains were not maintained. The analysis of the participants’ responses to how their behavior would change subsequent to the training revealed important themes including: (1) greater ability to identify/assess or recognize CSEC victims, (2) greater understanding and knowledge of CSEC, (3) increased ability to communicate, interact, and engage with CSEC victims, and (4) heightened desire to educate others and raise awareness about CSEC. Results also indicated that participants were very satisfied with the training and found it highly relevant to their work.     

The contribution of childhood family violence on later intimate partner violence among robbery victims

This study examined the relative contributions of the three forms of childhood family violence exposure on physical intimate partner violence (IPV) victimization among recent robbery victims and tested a gender-matching modeling prediction for IPV risk. Data from a sample of 103 male and 93 female victims of a robbery were analyzed to investigate the effects of exposure to childhood physical abuse (CPA), childhood sexual abuse (CSA), and witnessing parental violence on the likelihood of IPV in adulthood. As expected, witnessing parental violence was associated with a 2.4-fold increase in IPV for both men and women. Neither CPA nor CSA was significantly associated with IPV after accounting for the effect of witnessing parental violence. There was support for the gender-matching hypothesis with men more likely to report IPV if they had witnessed mother-to-father violence and women more likely to report IPV if they had witnessed father-to-mother violence. Witnessing parental violence is strongly associated with risk for IPV victimization, particularly when the victim is the same-gender parent. Future directions and clinical implications are discussed.     

Recommended Distributions for Exposure Factors Frequently Used in Health Risk Assessment

Although there has been nearly complete agreement in the scientific community that Monte Carlo techniques represent a significant improvement in the exposure assessment process, virtually all state and federal risk assessments still rely on the traditional point estimate approach. One of the rate-determining steps to a timely implementation of Monte Carlo techniques to regulatory decision making is the development of "standard" data distributions that are considered applicable to any setting. For many exposure variables, there is no need to wait any longer to adopt Monte Carlo techniques into regulatory policy since there is a wealth of data from which a robust distribution can be developed and ample evidence to indicate that the variable is not significantly influenced by site-specific conditions. In this paper, we propose several distributions that can be considered standard and customary for most settings. Age-specific distributions for soil ingestion rates, inhalation rates, body weights, skin surface area, tapwater and fish consumption, residential occupancy and occupational tenure, and soil-on-skin adherence were developed. For each distribution offered in this paper, we discuss the adequacy of the database, derivation of the distribution, and applicability of the distribution to various settings and conditions.     

The History of Interest Inventories and Career Assessments in Career Counseling

Interest inventories and career assessments continue to be used to support practitioners as they work to uncover client interests, abilities, skills, motivations, values, and other personal factors that help individuals self‐define and construct their career. The skilled use of career inventories and assessments remains a minimum competency of career service providers' ability to successfully partner with their clients. A history of the evolution of assessment from 1914 through 1974 and considerations for the future of assessment are highlighted to provide historical perspective to inform practitioners as they serve the diverse needs of complex client populations.     

Teaching Statistics

This article compares grades earned by incoming MSW students in traditional classroom-based statistics courses and those taught using software-based content and no regular classes. Traditional-learning students earned high grades overall, regardless of prior undergraduate grade point average (GPA). Students in the electronic-learning course with high GPAs performed as well as students in the regular course. However, electronic-learning students with low GPAs earned lower course grades than students with high GPAs who took the same course and students in the traditional course, regardless of their GPA. Findings suggest students can learn statistics successfully in a programmed instruction/distance education course; however, some might need additional assistance or do better in a traditional format.
