Has Industrialization Benefited No One? Climate Change and the Non-Identity Problem

Within the climate justice debate, the ‘beneficiary pays’ principle holds that those who benefit from greenhouse emissions associated with industrialization ought to pay for the costs of mitigating and adapting to their adverse effects. This principle constitutes a claim of inter-generational justice, and it is widely believed that the non-identity problem raises serious difficulties for any such claim. After briefly sketching the rationale behind ‘beneficiary pays,’ this paper offers a new way of understanding the claim that persons in developed societies have benefited from industrialization. It argues that when we think of the claim in this new way, it evades the non-identity problem entirely. Some objections to this approach are then considered and rebutted. The paper concludes by comparing the present, relatively modest solution to the nonidentity problem with a much more ambitious attempt from the recent literature.     

Disclosure of Genetic Research Results to Members of a Founder Population

There is currently extensive discussion and debate in the literature on how, when, and to whom genetic research results should be returned (see Genetics in Medicine, April 2012 issue). Here, we describe our experience in disclosing genetic information on Mendelian disorders discovered during the course of our research in the Hutterites. We first assessed attitudes toward the disclosure of carrier results, which revealed that many individuals wanted carrier information and that many intended to use the information in family planning. Based on this information, we developed a pilot study to test and disclose cystic fibrosis (CF) carrier status. Next, a larger scale project was developed in order to disclose genetic research results for 14 diseases to those interested in receiving the information. We developed brochures, offered a live interactive educational program, conducted a consent process, and disclosed results in letters mailed to the consented individuals. Overall, ~80 % of individuals who participated in the educational program signed consent forms for the release of their results for 14 diseases. We describe our experience with returning individual genetic research results to participants in a population-based research study.     

Effect of Sn on microstructure and mechanical properties of (Ti–Cu)-based bulk metallic glasses

A Ti₄₃Zr₇Cu₄₃Ni₇ bulk metallic glass (BMG) exhibits a plastic strain of less than 0.2% under room-temperature compression. However, a Ti₄₅Zr₅Cu₄₀Ni_7.5Sn_2.5 BMG developed by addition of Sn to Ti₄₃Zr₇Cu₄₃Ni₇ shows a significant improvement of ～14.8% to the plastic strain with work hardening. Microstructural comparison of these BMGs reveals that the addition of Sn leads to formation of nano-scale chemical heterogeneities throughout the material. These nano-scale chemical fluctuations play an important role in enhancing the plastic strain of (Ti–Cu)-based BMGs.     

Don't derogate this message! Self-affirmation promotes online type 2 diabetes risk test taking

The aim of the present study was to examine whether self-affirmation promotes acceptance of threatening type 2 diabetes information and risk-testing behaviour. In an experimental study (N = 84), we manipulated self-affirmation by allowing participants to affirm a value that was either personally important or unimportant to them, and measured participants' risk level prior to reading threatening type 2 diabetes information. As dependent variables, we measured message derogation, intentions to do an online type 2 diabetes risk test and online risk-testing behaviour. Findings showed that self-affirmation decreased message derogation, increased intentions to do an online risk test and promoted online risk test taking among at-risk participants. Among participants not at-risk, self-affirmation decreased intentions and online risk test taking. Therefore, it is concluded, that for an at-risk population self-affirmation can decrease defensive responses to threatening health information and promote (online) risk test taking for diseases.     

What works best: objective statistics or a personal testimonial? An assessment of the persuasive effects of different types of message evidence on risk perception.

OBJECTIVE: In an experimental online study we compared the effects of different types of persuasive evidence in promoting the acceptance of a personal health risk. DESIGN: 118 men who have sex with men (MSM) at-risk for infection with the hepatitis B virus (HBV) were recruited via a range of websites and randomly assigned to one of 4 conditions (2 experimental and 2 control): narrative evidence (i.e., a personal account), statistical evidence (i.e., abstract prevalence data), mere assertion of increased risk, and no risk information. MAIN OUTCOME MEASURES: Narrative evidence was expected to be more effective than statistical evidence in increasing MSM's perceived risk of infection with HBV and intention to obtain vaccination. RESULTS AND CONCLUSION: As predicted, perceptions of personal risk and intention to obtain vaccination against HBV were highest after presentation of narrative evidence, and risk perception mediated the effect of type of message evidence on intention. We propose that narrative evidence effectively promotes a sense of personal risk because it is less affected by defensive message processing resulting from the threat to important self-beliefs that seems inherent in health risk communication.     

In the mood to face the facts: When a positive mood promotes systematic processing of self-threatening information

Two experiments tested the hypothesis that a positive mood can increase attendance to, and systematic processing of, threatening health information, particularly when the information is self-relevant. In Study 1, a positive mood increased differentiation between strong and weak arguments in a threatening health message about RSI only for participants who had received false feedback regarding their high vulnerability to RSI. Mood had no effects under conditions of low vulnerability. In Study 2, a positive mood speeded up responses to self-threatening words—compared with neutral words—for smokers who had just read a threatening health message about smoking. The authors conclude that fostering a positive mood may promote attendance to and systematic processing of information that threatens the self, and hence contribute to the success of health campaigns targeted at individuals who are vulnerable to specific health risks.

The Relationship of Positive Psychological Variables with the Age of Destitute Women in Psychosocial Adaptation

The purpose of the present investigation was to examine the importance of positive psychological variables like self-efficacy, optimism, hope, resilience, and well-being in the context of psychosocial adaptation of destitute women staying in rescue homes/short-stay homes in the coastal districts of Odisha, India and their relationship with their age and the implications for old age. The participants were individually administered measures of self-efficacy, optimism, resilience, hope, and well-being. Destitute and non-destitute women were compared on each of these measures. The sample consisted of 300 women (150 destitute women and 150 non-destitute women). The destitute women were randomly sampled from the short-stay homes/rescue homes in the coastal districts of Odisha. Though the age range was from 18 to 45 years (as that is the age they normally have the courage to raise a voice against injustice done to them), there are implications for their later life; if proper intervention programs are done to increase their positive psychological capital, better well-being can be ensured for their old age. The analysis of data involved Product Moment Correlation Coefficient between age and other dimensions. The major implications of the study were formulated and directions for future research were also outlined.     

The role of planning in different mathematical skills

Despite the fact that planning has been found to be a significant predictor of reading (particularly of reading comprehension), much less is known about its contribution to mathematics. The purpose of this study was to examine the role of two levels of planning (operation planning and action planning) in three mathematical skills (calculation fluency, math problem-solving, and math reasoning). Eighty Grade 2 children from Shanghai, China were assessed on measures of nonverbal cognitive ability (nonverbal matrices), working memory (digit span backwards and N-back), operation planning (matching numbers, planned codes, and planned search), action planning (crack the code), and mathematics (calculation fluency, math problem-solving, and math reasoning). The results of regression analyses showed that both levels of planning accounted for unique variance in mathematics over and above the effects of nonverbal cognitive ability and working memory. The effects of action planning were particularly strong in math problem-solving. These findings suggest that measures of planning could be used along with measures of working memory to detect children at-risk for mathematics disabilities and that intervention programmes targeting planning could be developed to boost children's mathematics performance.     

How terrorism news reports increase prejudice against outgroups: A terror management account

Three studies tested predictions derived from terror management theory (TMT) about the effects of terrorism news on prejudice. Exposure to terrorism news should confront receivers with thoughts about their own death, which, in turn, should increase prejudice toward outgroup members. Non-Muslim (Studies 1-3) and Muslim (Study 3) participants were exposed to news about either Islamic terrorist acts or to control news. When Dutch filmmaker Theo van Gogh was murdered in Amsterdam by an Islamic extremist during data collection of Study 1, this event was included as a naturally occurring factor in the design. Consistent with TMT, terrorism news and Van Gogh’s murder increased death-related thoughts. Death-related thoughts, in turn, increased prejudiced attitudes toward outgroup members, especially when participants had low self-esteem, and when terrorism was psychologically close. Terrorism news may inadvertently increase prejudiced attitudes towards outgroups when it reminds viewers of their own mortality.
