An information - expectation framework for decisions under uncertainty

Despite being in existence for many decades, normative decision theory has not become a commonly used tool for real-world decisions. This paper considers the reasons for this situation and suggestions for circumventing them. The main suggestion involves a two-stage framework in terms of the information available to the decision maker and his/her expectations under the available acts. This framework is well suited for decisions with incomplete structure, which is typical of real decision situations. Within this framework a specific multiplicative model is also discussed.     

Identification of shareholder ethics and responsibilities in online reverse auctions for construction projects

The increasing number of companies providing internet services and auction tools helped popularize the online reverse auction trend for purchasing commodities and services in the last decade. As a result, a number of owners, both public and private, accepted the online reverse auctions as the bidding technique for their construction projects. Owners, while trying to minimize their costs for construction projects, are also required to address their ethical responsibilities to the shareholders. In the case of online reverse auctions for construction projects, the ethical issues involved in the bidding technique directly reflects on the owner’s ethical and social responsibilities to their shareholders. The goal of this paper is to identify the shareholder ethics and responsibilities in online reverse auctions for construction projects by analyzing the ethical issues for the parties involved in the process. The identification of the ethical issues and responsibilities requires clear definition and understanding of professional ethics and the roles of the involved parties. In this paper, first, the concept of professional ethics and social responsibility is described in a general form. To illustrate the ethical issues and responsibilities, a sample case of bidding for a construction project using online reverse auction techniques is presented in which the shareholders were actively involved in questioning the ethical issues. The issues involved in the bidding process and their reflection on the shareholder responsibilities are described and analyzed for each stage of the process. A brief discussion of the overall process is also included to address the general ethical issues involved in online reverse auctions. An earlier version of this paper was presented at the “Ethics and Social Responsibility in Engineering and Technology” meeting, New Orleans, 2003.     

Relationships between core ideological motives,social and economic conservatism,and religiosity: Evidence from a Turkish sample

The “conservatism as motivated social cognition” approach posits two core ideological motives underlying political conservatism across cultures. However, there is a scarcity of tests from non‐Western cultures, and much research has failed to distinguish between social and economic conservatism. Using a relatively large undergraduate sample from a non‐Western, predominantly Muslim country (Turkey), we tested the associations among resistance to change and opposition to equality motives, social and economic conservatism, right‐wing political orientation, and religiosity. In line with the “conservatism as motivated social cognition” account, we found that (a) social conservatism is more strongly related to resistance to change (rather than opposition to equality), (b) economic conservatism is more strongly related to opposition to equality (rather than resistance to change), (c) social conservatism is the strongest predictor of right‐wing political orientation among other conservatism measures, and (d) political orientation and religiosity had divergent effects: While right‐wing political orientation was related to economic conservatism, religiosity was inversely related to the latter, providing support for previous work indicating a resemblance between leftists and Islamists in Turkey. The results generally support the motivated social cognition approach to conservatism while also highlighting the importance of distinguishing between social and economic conservatism.     

High-pressure torsion of metastable austenitic stainless steel at moderate temperatures

We subjected samples of a 304 metastable austenitic stainless steel to high-pressure torsion (HPT) in the temperature range of 303–573 K, (i.e. at different austenite stabilities), to examine their microstructures and mechanical properties. HPT processing at room temperature led to the formation of a lamellar microstructure with austenitic and martensitic phases, of which sizes were characterised by prior austenite grains, whereas HPT processing at moderate temperatures produced nanostructured austenite grains through mechanical twinning. The nanostructured 304 steel with an average grain size of ~70 nm exhibited a fine balance between tensile strength (~1.7 GPa) and reduction of area (~55%).     

Does survival context enhance memory for source? A within-subjects comparison

ABSTRACT

Nairne, Thompson, and Pandeirada [2007. Adaptive memory: Survival processing enhances retention. Journal of Experimental Psychology: Learning, Memory, and Cognition, 33, 263–273] demonstrated that processing words according to their relevance to a survival scenario enhanced their subsequent retrieval in recall and recognition tasks compared to a variety of control scenarios. From an adaptive perspective, it is maintained that processing words in a survival context should also enhance memory for source; however, evidence in the literature is rather mixed regarding a survival context advantage for source memory. In the current study, we conducted four experiments to systematically investigate the survival advantage in source memory, when the context itself is the source, with both recall (Experiments 1A and 1B) and recognition tests (Experiments 2A and 2B). Results showed a survival advantage for item memory over the control contexts in all experiments. The survival context advantage was not extended to source memory performance in Experiment 1A. Results from all other experiments, however, indicated a survival context advantage for both item and source memory. Findings are discussed in relation to possible proximate mechanisms underlying the survival processing effect.     

Recognition accuracy for original and altered verbal memory reports in older adults

The current study examined four factors that were expected to influence recognition accuracy of previously retrieved events: remoteness of the event, rated emotionality of the event, the type of changes that were made to the original memory report, and the plausibility of these changes. This was done in a study with 33 participants who were tested for recognition accuracy of original and altered reports a year after they had initially reported these autobiographical memories. Participants evaluated original and altered reports as being authentic or not. High recognition accuracy occurred for report evaluations of events that were recent, that contained central changes, and that had higher emotional intensity ratings. Recognition errors were more likely to occur when the original events were remote and when altered reports contained peripheral and plausible changes. These findings demonstrate the vulnerability of recognition accuracy in older adults under difficult retrieval conditions.     

Perceptual invariance and the psychophysical law

The psychophysical power law, demonstrated empirically by Stevens, is derivable from two postulates concerning (1) the tendency of perceptual organizations to model the environment and (2) the tendency for perceptual relations to remain constant. The two postulates appear to rule out logarithmic laws of the Fechner type. The theory is extendable to multidimensional perceptions such as those encountered in speech and color vision. The power transformations produced by the sense organs may be of such form that they produce a perceptual space in which subsequent transformations need be only linear.     

Do changes in threat salience predict the moral content of sermons? The case of Friday Khutbas in Turkey

We analyzed the content of “Friday Khutbas” delivered in Turkish mosques between January 2001 and December 2018 to test the prediction of moral foundations theory (MFT) literature that threat salience would lead to an increased endorsement of binding moral foundations. As societal-level indicators of threat, we examined (a) historical data on the proportion of terrorism-related news published in a Turkish newspaper, (b) the geopolitical risk score of Turkey as measured by Geopolitical Risk Index, and (c) Google Trends data on the search frequency of words “terror”, “terrorism”, or “terrorist”. To measure the endorsement of moral foundations, we built a Turkish Moral Foundations Dictionary and counted the relative frequency of morality-related words in the khutbas delivered in Istanbul, Turkey. Time series analyses showed that risk salience in a certain month was positively related to endorsement of the loyalty/betrayal foundation in that month’s Friday Khutbas. There were mixed results for the other moral foundations.     

Pakistan Federal Shariat Court's Collective Ijtihād on Gender Equality,Women's Rights and the Right to Family Life

This article argues on the basis of recent case law that the judges of the Pakistan Federal Shariat Court (FSC) have asserted their right to ijtihād and have indeed engaged in collective ijtihād. While in some areas, such as freedom of religion, Islamic law has been interpreted rigidly in a non-human-rights-friendly fashion in Pakistan, in some other areas, the flexibility and pluralism of Islamic law has been used to improve gender equality, women's rights and the right to family life. By using its constitutional powers, with its collective ijtihād, the FSC has been tackling the traditionally illiberal interpretation and application of Muslim laws in these areas. Regardless of the methodology and process of this ijtihādic endeavor, the output shows that the FSC has been either modifying the traditional ijtihāds or coming up with totally new ijtihāds to answer contemporary questions faced by Islamic law. The findings of the article once again challenge the views of scholars such as Schacht, Coulson and Chehata, who have argued that, by the fourth/tenth century, the essentials of Islamic legal doctrine were already fully formulated and that the doctrine remained fixed.
