Qualitative Heuristics For Balancing the Pros and Cons

Balancing the pros and cons of two options is undoubtedly a very appealing decision procedure, but one that has received scarce scientific attention so far, either formally or empirically. We describe a formal framework for pros and cons decisions, where the arguments under consideration can be of varying importance, but whose importance cannot be precisely quantified. We then define eight heuristics for balancing these pros and cons, and compare the predictions of these to the choices made by 62 human participants on a selection of 33 situations. The Levelwise Tallying heuristic clearly emerges as a winner in this competition. Further refinements of this heuristic are considered in the discussion, as well as its relation to Take the Best and Cumulative Prospect Theory.     

Human Development Index (HDI) Rank-Order Variability

In accordance with the increasing demand for information, indices are created and national and global rankings made to represent and through which to understand and build policy related to complex situations, processes and trajectories. Different indices for a single concept are also created that have advantages or disadvantages over one another or to overcome certain calculation problems. As one such, the Human Development Index (HDI) presently lists countries according to four different criteria, and remains at the heart of democratic and humanitarian recovery efforts. This type of indicator is taken as a function of past performances, with high performances being the extreme values at positively skewed distributions. Thus, the variability of each unit’s repeated measures is regarded as the result of efforts made between the measurement time points (in the HDI case, of a country to promote development). However, it is assumed that the variability of the units is not homogenous. Here, it is shown that in the HDI case, high performance units show relatively low variability, whereas the middle and middle-low performance units show a high variability. Cluster analysis and Friedman test have been used to determine the characteristics of ordered country rankings. The variability of rank-order should also be taken into account besides the location on the list by clustering the countries according to HDI.     

Homosexuality in Turkey: Strategies for Managing Heterosexism

The goal of this study was to identify the strategies used by young homosexuals to manage their sexual minority status in Turkey. In-depth interviews were conducted with 15 self-identified homosexual university students. The data on the strategies employed by homosexuals suggested a categorization of these strategies into four interrelated areas: strategies employed in the process of self-acceptance; strategies to manage sexual stigma and prejudice; strategies specific to the coming-out process; and the strategies used while openly expressing their sexual identities.     

Another Child? Fertility Ideals,Resources and Opportunities

Low fertility in most developed countries has prompted policy concern in relation to labour market supply, pensions, and expenditure on health and welfare services as well as policy debate about both the cost of children and the opportunity costs of parenthood. The extent to which family policy interventions can be effective in slowing or reversing fertility decline is much debated. This paper, based on a fertility module of the Scottish Social Attitudes Survey 2005, examines the current fertility, and ideal and expected fertility of a nationally representative sample of 455 parents of reproductive age and focuses on whether they plan to have another child. It compares the characteristics of those who intend to have another child with those who do not, and how parents with one child differ from those with more children. It addresses three questions about family size: (1) fertility ideals, (2) resources and the economic implications of childbearing, and (3) opportunities for childbearing and the effects of a late start on fertility expectations. It concludes that, despite a sustained period of low fertility in Scotland, childbearing ideals are robust and explanations of low fertility must derive from difficulties in realising those ideals. Difficulties in realising fertility aspirations are associated less with resources than with opportunities for childbearing, especially the timing of first birth. Those who delay their first birth are less likely to realise their ideal family size, and their lower fertility is associated with the opportunity costs of childbearing in terms of foregone qualifications, careers and earnings.     

Towards sustainability by aligning operational programmes and sustainable performance measures

Abstract

In the last decades, sustainable concerns have increasingly gained importance to organizational survival, and Lean/Six Sigma approaches are becoming more and more outstanding in order to improve sustainability performance. This article aims to evaluate the degree of importance of sustainable performance measures of Brazilian organizations and to propose guidelines to achieve sustainability by aligning these measures with operational improvement programmes. Multiple data collection methods were applied as theoretical literature review, questionnaire survey and semi-structured interviews with industry professionals and academic researchers. The findings show that it is the corporate responsibility to focus their efforts on both operational improvement programmes and sustainable initiatives in order to achieve better environmental protection, corporate reputation, quality management, cost performance and suppliers relations, as they are considered to be more important on organizational sustainability.     

Ports of Mucuripe and Pecém, Ceará, Brazil: restructuring process and its impact on workers' health

This paper presents a comparative study of working conditions and health hazards of two ports in the state of Ceará: Mucuripe and Pecém, focusing workers in the various categories involved in the operational activities of the two ports. The aim is to investigate changes implemented by the restructuring process of ports arising from the Port Modernization Act. In the case of Ceará, the organization and control of work at the mentioned ports occur differently: Mucuripe, the oldest port, had to adapt to the changes enforced by the Modernization Act and Pecém, called Port Terminal, inaugurated in 2001, "was born modern". To achieve our objective, we carried out field work, using Ergonomic Work Analysis. Systematic observations were made of the various activities carried out by workers, as well as interviews with managers, workers and trade unionists. Container operations and other activities of the two ports were recorded in film and presented to groups of workers (focus groups) in order to better understand work organization and the main differences in tasks carried out in the two ports. Each reality presents different characteristics regarding port operations, type of work and labor control. Results indicate that due to the technological innovations, the restructuring process reduced some risks, but brought new occupational hazards and intensification of work.     

Fertility and social change: the neglected contribution of men's approaches to becoming partners and parents

Attitude survey and interview data are mobilised to address neglect of men's contribution to low fertility and wider social change in families and relationships. Men's attitudes are as relevant as women's to understanding fertility behaviour. However, fertility behaviour can only be understood in the context of a package of changes in gender relations and family life. Data from a random sample of men aged 18–49 surveyed in the Scottish Social Attitudes (SSA) survey 2005/06 are combined with in‐depth interviews conducted in 2007 with 75 men aged 25–44 identified through the Scottish Household Survey as not living in co‐resident partnership arrangements. Both datasets encompass the age span conventionally associated with having children and men who were the potential partners of women delaying a first child until their 30s. They allow consideration of the impact of social contact with parents and children on men's fertility intentions and how the role of provider features in men's views about parenting. The interviews focus on men who have fallen out of, or have not entered, co‐resident partnerships and examine the relationship between partnering and parenting. In combination the data suggest how men act as a complementary or contradictory downward drag on women's fertility and that their role has been underestimated in understanding the package of family change of which low fertility is a part.     

Thermal,viscoelastic and mechanical properties' optimization of polyphenylene sulfide via optimal processing parameters using the Taguchi method

Thermal, viscoelastic and mechanical properties of polyphenylene sulfide (PPS) were optimized as a function of extrusion and injection molding parameters. For this purpose, design of experiments approach utilizing Taguchi's L₂₇ (3⁷) orthogonal arrays was used. Effect of the parameters on desired properties was determined using the analysis of variance. Differential scanning calorimeter (DSC) tests were performed for the analysis of thermal properties such as melting temperature (T_m) and melting enthalpy (ΔH_M). Dynamic mechanical analysis (DMA) tests were performed for the analysis of viscoelastic properties such as damping factor (tan?δ) and glass transition temperature (T_g). Tensile tests were performed for the analysis of mechanical properties such as tensile strength and modulus. With optimized process parameters, verification DSC, DMA and tensile tests were performed for thermal, viscoelastic and mechanical properties, respectively. The Taguchi method showed that ‘barrel temperature’ and its level of ‘340°C’ were seen to be the most effective parameter and its level; respectively. It was suggested that PPS can be reinforced for further improvement after optimized thermal, viscoelastic and mechanical properties.
