Faithful Allies: The Experiences of LGB-Affirming,White Christian Clergy

In this study, the authors explored the growing subset of Christian clergy who are allies of the LGB community and invested in fostering change in their religious communities toward the end of making Christianity more affirming and inclusive. Thirteen heterosexually identified, White Christian clergy participated in this qualitative study of their daily lived experiences; the data were analyzed using Consensual Qualitative Research. The findings provide detailed information about these clergy including the factors that fostered the development of their worldviews, the behavioral manifestation of their advocacy, and the beliefs and experiences that sustain their efforts.     

Measuring Hope in the Philippines: Validating the Short Version of the Locus-of-Hope Scale in Filipino

A short version of the locus-of-hope Scale was developed and translated into the Filipino language for the purpose of assessing hope in Filipinos who have lower levels of education and who may not have adequate levels of proficiency in English. The 20-item scale had four locus-of-hope subscales (internal, external-family, external-peers, and external-spiritual) each with four items (another four were filler items); all items described thoughts associated with some capacity and strategy to attain important goals in life. A sample (N = 362) of adults from communities in Metro Manila were asked to answer the scale, as well as measures of optimism, self-esteem, and life satisfaction. Confirmatory factor analysis indicated an adequate fit between the hypothesized four-factor structure and the data, but the internal locus-of-hope scale was found to have low internal consistency. Regression analysis showed positive associations between the internal and external-family locus-of-hope subscales and the three measures of wellbeing. But external-peers locus-of-hope was negatively associated with optimism and self-esteem, and external-spiritual locus-of-hope was positively related with optimism.     

Lean and green in the transport and logistics sector – a case study of simultaneous deployment

The transport and logistics sector is of vital importance for the stimulation of trade and hence the economic development of nations. However, over the last few years, this sector has taken central stage in the green agenda due to the negative environmental effects derived from its operations. Several disciplines including operations research and sub-areas of supply chain management such as green supply chains, green logistics and reverse logistics have tried to address this problem. However, despite the work undertaken through these disciplines, theoretical or empirical research into the sequential or simultaneous deployment of the lean and green paradigms, particularly, in the road transport and logistics sector is limited. This paper presents a case study where both paradigms have been combined to improve the transport operations of a world leader logistics organisation in the metropolitan area of Monterrey, Mexico. To do this, a systematic methodology and a novel tool called Sustainable Transportation Value Stream Map (STVSM) were proposed. The results obtained from the case study indicate that the concurrent deployment of the green and lean paradigms through such methodology and the STVSM tool is an effective approach to improve both operational efficiency and environmental performance of road transport operations. The paper can be used as a guiding reference for transport and logistics organisations to undertake improvement projects similar to the one presented in this paper. Additionally, this research also intends to stimulate scholarly research into the application of lean and green paradigms in the transport and logistics sector to expand the limited research pursued in this area.     

Ryff’s Six-factor Model of Psychological Well-being, A Spanish Exploration

This article aims to provide researchers interested in using Ryff’s Scales of Psychological Wellbeing with additional information to make an informed decision on the scales and items to use. It builds on the discussion in the literature on the six factor structure of this measure. An alternative shortened version of this wellbeing measure (Van Dierendonck 2004). Personality and Individual Differences, 36, 629–643) was analyzed in a combined Spanish language sample from Spain and Columbia. Using confirmatory factor analysis, one-, two-, three- and six-factor models were compared. The results showed that indeed four out the six dimensions overlapped considerably. Nevertheless, the model that fit the data best was the six factor model with one underlying second order well-being factor, hereby confirming Ryff’s model in a non-Anglo–Saxon culture.     

Discussion of “On simulation and properties of the stable law” by L. Devroye and L. James

We contribute to the discussion of the paper by Devroye and James, by reviewing some of the most meaningful results that relate the unilateral stable distribution with the asymptotic behavior of the so-called Ewens-Pitman sampling model. Our focus is then on how these results have been exploited in the context of Bayesian nonparametric inference for species sampling problems.     

Lean road transportation – a systematic method for the improvement of road transport operations

Road transportation has become an important factor in international trade and the management of supply chains. However, this form of product logistics has generally been considered inefficient. Traditionally, practical inefficiencies of road transportation have been addressed through mathematical modelling, operations research-based methods and simulation. This paper presents an alternative systematic approach to improve road transport operations based on lean thinking and the reduction of the seven transportation extended wastes. To do this, the paper reviews the extant literature in the area of lean road transportation, providing a structured research definition of the application of lean thinking in road transport operations and hence guidance on the limited research conducted in this field. The systematic lean transportation method is then presented and empirically tested through a case study in a Mexican firm. The results obtained from the case study indicate that the proposed systematic lean method is an effective alternative for the improvement of road transport operations, with the number of distribution routes and distance travelled being reduced by 27 and 32%, respectively. The proposed method can be used by organisations as a guide to help them improve their road transport operations. In addition, the paper’s aim is to contribute by stimulating scholars to further study the application of lean thinking and waste reduction in road transport operations.     

Plurality Rule Works In Three-Candidate Elections

In the citizen–candidate approach each citizen chooses whether or not to run as candidate. In a single-peaked preference domain, we find that the strategic entry decision of the candidates eliminates one of the most undesirable properties of Plurality rule, namely to elect a poor candidate in three-candidate elections since as we show, the Condorcet winner among the self-declared candidates is always elected. We find that the equilibria with three candidates are basically 2-fold, either there are two right-wing candidates and a left-wing candidate who wins the elections (or its symmetric), or there is a right-wing candidate, a left-wing candidate, and a candidate located in between the two others who becomes winner. We also show that when four or more candidates enter the contest, Plurality rule can elect the Condorcet-loser among the self-declared candidates.      

Strategic requirements with indifference: single-peaked versus single-plateaued preferences

We concentrate on the problem of the provision of one pure public good whenever agents that form the society have either single-plateaued preferences or single-peaked preferences over the set of alternatives. We are interested in comparing the relationships between different nonmanipulability notions under these two domains. On the single-peaked domain, under strategy-proofness, non-bossiness is equivalent to convexity of the range. Thus, minmax rules are the only strategy-proof non-bossy rules. On the single-plateaued domain, only constant rules are non-bossy or Maskin monotonic; but strategy-proofness and weak non-bossiness are equivalent to weak Maskin monotonicity. Moreover, strategy-proofness and plateau-invariance guarantee convexity of the range.
