Evolution of communication in perfect and imperfect worlds

We extend previous work on cooperation to some related questions regarding the evolution of simple forms of communication. The evolution of cooperation within the iterated Prisoner's Dilemma has been shown to follow different patterns, with significantly different outcomes, depending on whether the features of the model are classically perfect or stochastically imperfect (Axelrod, 1980a,b, 1984, 1985; Axelrod and Hamilton, 1981; Nowak and Sigmund, 1990, 1992; Sigmund, 1993). Our results here show that the same holds for communication. Within a simple model, the evolution of communication seems to require a stochastically imperfect world.     

Good intentions and failed implementations: Understanding culture-based resistance to organizational change

Based on the insight that culture shapes resistance to change in an organization, and the recognition that cultures of organizations are embedded in a broader societal culture, this study seeks to provide empirical evidence on how societal-based cultural understandings and values within an organization serve as a source of resistance to change among employees. The study is based on a case study of a medium-sized Turkish company. The study shows how certain managerial decisions toward a professionally running organizational design are difficult to implement due to societal-based patterns of understandings and meaning systems gathered around status, hierarchy, and emotion-based (personalized) relations in the company.     

Intimate partner violence: A narrative review of the biological and psychological explanations for its causation

Intimate partner violence (IPV) is a major social and public health problem that affects men and women across the globe regardless of their culture, religion and other demographic characteristics. During the last 100 years many different theories have been proposed to explain the phenomenon of IPV. Much research is been conducted using these theories as a guiding or underlying framework. However, it is difficult to find a single account that provides a succinct and up-to-date overview of these theories. As a result considerable effort is required to identify and retrieve relevant papers to understand the various theories which attempt to explain IPV. This article attempts to provide a succinct and up-to-date integrative review of the biological and psychological explanations of IPV. Both perspectives have been critically evaluated in the light of the available literature and an attempt has been made to discuss the strengths and limitations of each perspective in shedding light on the causation of IPV.     

Strategies adopted by Turkish adults for increasing happiness in daily life

The present study aims to focus on the strategies adopted by adults in seeking ways to increase happiness in their daily life and to determine whether or not significant differences exist between happiness levels in adults at the very beginning and the end of a four-month period. Sixty-eight adults who were found eligible were included in this study. The research method is of a mixed type. The distinguishing feature of this study is the experience sampling method employed. Positive–Negative Affect and Satisfaction with Life Scales, an experience sampling data form and a personal information form were used in the study. The study results show that adults adopt various strategies in order to get rid of their unhappiness and increase their happiness in three contexts. No statistical significance could be determined between the measurements achieved at the beginning and at the end of the study into the happiness of the participants.     

Spatial distinctiveness effect in categorisation

The aim of the present study was to show that the probability of an item being retrieved is proportional to its spatial distinctiveness, and that this distinctiveness effect can be obtained in an implicit memory task. The participants were presented with two phases in which they had to categorise pictures of objects as either “kitchen utensils” or “do-it-yourself tools”. In our encoding phase, the pictures were successively presented in different positions on the screen. The positions were arranged in one of two different configurations: a “distinctive condition” in which the pictures were placed in two circles, one central and one peripheral, such that the distance between the pictures was greater when they were in a peripheral position than in a central position, and a “nondistinctive” condition, in which the distance between the pictures was constant irrespective of their central or peripheral position. In the test phase, the same pictures were presented for categorisation, mixed with new pictures at the centre of the screen. The results clearly confirmed our expectations.     

Probability matching: encouraging optimal responding in humans.

Two hundred undergraduate students participated in a repeated-trials binary choice procedure in which choice of one outcome was correct on 75% of trials. Subjects received 192 trials and were divided into five conditions: (1) control; (2) subjects were given the actual probabilities; (3) subjects were told if they did well they could leave early; (4) competition condition; (5) midway through the task subjects were asked to recommend a strategy for another subject. Half of the subjects in each group were told that the best they could do was to be correct on 75% of the trials. This manipulation permitted assessment of the hypothesis that subjects in probability-matching tasks are seeking a strategy that will be correct on 100% of the trials. The results partially confirmed this hypothesis. In addition, two of the variables improved performance significantly (giving probabilities and asking subjects to recommend a strategy). However, while subjects in all groups improved significantly over trials, optimal choice did not occur in this task.     

Knowledge,Attitude, and Practice of Clerical Students with Respect to HIV/AIDS in Iran, 2011

In this study, knowledge and attitude of Iranian clerical students toward HIV and AIDS was assessed. Through a cross-sectional study, 367 clerical students were surveyed, in convenience sampling method, in the Qom seminary in 2011, utilizing a self-administered structured questionnaire. The questionnaire was piloted on 20 clerical student volunteers, internal consistency measured with Cronbach’s alpha was 0.89. Participants’ scores of knowledge and attitude were calculated out of 100. The level of knowledge in 37.33 % of participants was good (scores >80), whereas 46.05 and 16.62 % had moderate (40 < scores ≤ 80) and poor (scores ≤40) levels of knowledge, respectively. The mean score of knowledge and attitude was 58.29 (95 % CI 56.11–60) and 77.26 (95 % CI 75.92–78.59) out of 100, respectively. A significant correlation was observed between level of knowledge and attitude (r = 0.33, P < 0.001). Knowledge score appeared to be significantly higher in women compared to men (p = 0.04). With an increase in age, the level of knowledge significantly decreased (r = ?0.10, P = 0.02). We could also detect a statistically significant relationship between attending educational courses on HIV/AIDS and inclusion of HIV/AIDS topics in the individual’s sermons (P < 0.001). Although clerical students had shown some sort of positive attitudes toward HIV, their knowledge still needs to be improved to enable them to deliver more accurate information to the community during the course of their speeches. Having HIV-related courses as part of their curriculum or aside may contribute a lot to this.     

Healing Faith: A Qualitative Exploration of Latina Breast Cancer Survivors

Latina cancer survivors report higher levels of distress and depression and lower levels of social quality of life and overall health‐related quality of life when compared with all other cancer survivors. Cultural values influence cancer survivorship; however, little research to date has examined how aspects of the Latina culture may be healing during the cancer journey. Therefore, the purpose of this article is to present findings from a qualitative study exploring the influence of culture on quality of life for Latina breast cancer survivors. The authors use consensual qualitative research to understand the lived experiences of Latina breast cancer survivors.
