Modeling cost-delivery trade-offs for distribution logistics by a generalized PVRP model

This article provides a mathematical model to support management in making decisions about cost-delivery trade-offs in the case of cost-delivery flexibilities in distribution logistics. The optimization problem can be modeled as a bi-objective periodic vehicle routing problem, which is known as NP-hard. In the periodic vehicle routing problem considered in this study, no delivery patterns are pre-defined, instead the patterns are the result of the optimization process of the model. In addition, delivery time flexibilities are incorporated in the model. A heuristic solution method for realistic problem sizes is based on the tabu search procedure, and a real case study illustrates the applicability of the solution concept.     

Smallpox and Its Eradication in Finland: Implications for Disease Control

Cause-specific mortality studies are vital for a full understanding of the determinants of mortality and epidemiological transitions. The exceptional detail and accuracy of archival materials in Finland, as well as the length of the period covered, offer an ideal opportunity for such analyses. Focussing upon the late nineteenth and early twentieth centuries, the history, decline, and eventual eradication of smallpox is detailed. It has often been argued that primary vaccination in childhood was the major factor responsible for the decline and subsequent elimination of the disease in Finland. This perspective is probably correct for the initial decrease in smallpox mortality. To interpret the final phases of smallpox history in Finland, however, several factors must be taken into consideration. These include revaccination, virulence of the virus, containment (quarantine) of infected individuals, vaccination of contacts, and importation of the virus from surrounding countries. While these factors were not of equal causal importance, they exerted a synergistic effect on the course of Finnish smallpox history. This in-depth historical case study demonstrates that multiple factors must be taken into account when disease control policies in developing countries are formulated to-day.     

El tema de la pregunta y la elaboración de las respuestas en la detección de mentiras

Los resultados obtenidos señalaron que la implicación personal en el tema facilita el reconocimiento de las respuestas falsas, a la vez que la preparación previa de las respuestas dificulta la detección de mentiras a jueces no entrenados.     

Negotiating Control: From Recognizing a Need to Making a Decision to Apply for a Housing Adaptation

ABSTRACT

A housing adaptation (HA) can enable independent living in one's own home, but deciding to change the home environment can be a thought-provoking matter. The aim of this study was to explore the applicant's perspective and decision-making process when applying for an HA grant. Seventeen persons were interviewed about their application for such a grant, and the data were analyzed using a constant comparative approach. The findings illustrated how the participants negotiated control in their everyday lives as they went from recognizing a need to then deciding to apply for an HA grant. Before coming to a decision, alternative solutions were considered and their expectations on the effect of having an HA were explored. This knowledge is useful for professionals and caregivers to help support people during the HA decision-making process.     

The Use of Chemical Restraints for Older Long-Term Hospital Patients: A Case Report from Finland

The purpose of this study was to describe the use and concomitant use of psychotropics and other drugs as chemical restraints in the aged in long-term hospital care. The study consisted of 154 patients (42 men, 112 women) hospitalized in five long-term care wards in Pori City Hospital, Finland. Three or more psychotropics were regularly given to 33% of the patients and regularly or irregularly to 53% of the patients. Two or more benzodiazepine derivatives or related drugs were regularly given to 24% of the patients and regularly or irregularly to 46% of the patients. The very poor cognitive and functional abilities of the patients, the common concomitant use of psychotropic drugs, the use of psychotropics to control the behavior of the patients, and the lack of documentation of the effects and side effects of the drugs give rise to the conclusion that psychotropics were used as chemical restraints in these long-term care wards.     

Implications of Male and Female Same-Gender Dyads

ABSTRACT

A sample of 222 Swedish social services officers were surveyed in regard to their opinions on a fictitious case addressing the needs of a same-gender client. The 49-question survey was statistically analyzed through a comparison of female and male same-gender dyads. The findings suggest that gender is an important factor in assessment, and this seems to be influenced by the gender of the client, the gender of the assessor, and how the problem area or situation of the client is “gendered.” Also, same-gender dyads tend to strengthen stereotypical expectations of men and women as clients and influence what forms of assistance are offered to the client. The male same-gender dyad tends to reduce the likelihood of assistance being offered, while the female same-gender dyad increased it. These results suggest that assessments are based upon stereotypical beliefs about men and women rather than being focused directly on individual differences and needs. Further research is recommended that incorporates a number of more refined “gendered” problem areas and situations and how these assessments can affect social work practice.     

Gendered and classed activist identity in the Russian oppositional youth movement

This article examines how activist identity is constructed in the Russian opposition youth movement Oborona. The research is based on fieldwork among youth activists in Moscow and St Petersburg. The author analyses how activist identity is classed and gendered, as well as its relations to the Russian civic field. The article suggests, first, that the activist identity is marked by an affiliation with the intelligentsia: activists have grown up in intelligentsia families and articulate their activities through the intelligentsia's ‘markers’, such as intelligence, discussion skills and education. Secondly, activists follow a dissidents' cultural model, by emphasizing the importance of non‐conformism and traditional dissident values, and draw parallels between the contemporary government and the totalitarian Soviet state. Thirdly, this traditional intellectual dissident identity is associated with cosmopolitanism through the movement's international connections and appropriation of the forms of action of global social movements. Sometimes the activist practices and aspirations conflict with the group's ideals. Furthermore, the activist identity is gendered and embodied in the right activist ‘look’, which is defined by masculinity. Regardless of the movement's liberal ideals in regards to democracy, questions of gender and sexuality are not discussed, and activists do not question traditional understandings of gendered divisions of labour.     

Development of an assessment tool to evaluate the risk potential of different gambling types

Based on different characteristics of gambling types, this study aimed to develop an assessment tool to evaluate the risk potential of available and planned gambling types in German-speaking countries. In the first module, 26 experts were interviewed over the course of a Delphi study, and an analysis of those results led to the selection of relevant characteristics and scaling values. Building on the first module, the second module consisted of standardized data collection of nonproblem, problem and pathological gamblers (characteristics: n = 363; scales: n = 356), which served as an empirical validation. Ten characteristics were identified with different weights and differentiated scaling values to evaluate the risk potential, and a psychometric validation indicated that the assessment tool was reliable (α = 0.91; r _ik  = 0.50; r _it  = 0.33–0.80). The correlation measures from data of epidemiological studies (R ² = 0.84) and a treatment survey (p < 0.001) demonstrated that the assessment tool was valid. This assessment tool, which was verified by psychometric validation, can serve the legislation and jurisdiction, the gaming industry and consumers as a future basis for risk evaluation of gambling types.     

The Emergence and Stability of the Attentional Bias to Fearful Faces in Infancy

Several studies have shown that at 7 months of age, infants display an attentional bias toward fearful facial expressions. In this study, we analyzed visual attention and heart rate data from a cross‐sectional study with 5‐, 7‐, 9‐, and 11‐month‐old infants (Experiment 1) and visual attention from a longitudinal study with 5‐ and 7‐month‐old infants (Experiment 2) to examine the emergence and stability of the attentional bias to fearful facial expressions. In both experiments, the attentional bias to fearful faces appeared to emerge between 5 and 7 months of age: 5‐month‐olds did not show a difference in disengaging attention from fearful and nonfearful faces, whereas 7‐ and 9‐month‐old infants had a lower probability of disengaging attention from fearful than nonfearful faces. Across the age groups, heart rate (HR) data (Experiment 1) showed a more pronounced and longer‐lasting HR deceleration to fearful than nonfearful expressions. The results are discussed in relation to the development of the perception and experience of fear and the interaction between emotional and attentional processes.
