Al-D˛am L ¥ r,Human Conscience and Christian-Muslim Relations

Can human conscience be a uniting bond between Christians and Muslims, across moral and religious differences? This article discusses the notion of d?am L ¥ r as employed by the Egyptian Muslim authors ?Abba ¥ s Mah?mu ¥ d al-?Aqqa ¥ d, Kha ¥ lid Muh?ammad Kha ¥ lid and M. Ka ¥ mil H?usayn. In the 1950s and 1960s, these authors used the notion of d?am L ¥ r to express the inward dimension of Islamic ethics. As Islamic humanists, they also used it to express what Muhammad and Jesus, Muslims and Christians, may 'know together' in the field of ethics. The modern Egyptian material is related to some observations on the semantic history of d?am L ¥ r, and a discussion of the conceptual history of conscience in Christian tradition and European philosophy. The article proposes that a constitutive element in the notion of conscience is the tension between 'knowing by oneself' and 'knowing with others'. In a broader perspective, the article discusses conscience as a globalized concept, and its importance for a Christian-Muslim dialogue which respects the difference of the Other.     

Lidocaine attenuates anisomycin-induced amnesia and release of norepinephrine in the amygdala

When administered near the time of training, protein synthesis inhibitors such as anisomycin impair later memory. A common interpretation of these findings is that memory consolidation requires new protein synthesis initiated by training. However, recent findings support an alternative interpretation that abnormally large increases in neurotransmitter release after injections of anisomycin may be responsible for producing amnesia. In the present study, a local anesthetic was administered prior to anisomycin injections in an attempt to mitigate neurotransmitter actions and thereby attenuate the resulting amnesia. Rats received lidocaine and anisomycin injections into the amygdala 130 and 120 min, respectively, prior to inhibitory avoidance training. Memory tests 48 h later revealed that lidocaine attenuated anisomycin-induced amnesia. In other rats, in vivo microdialysis was performed at the site of amygdala infusion of lidocaine and anisomycin. As seen previously, anisomycin injections produced large increases in release of norepinephrine in the amygdala. Lidocaine attenuated the anisomycin-induced increase in release of norepinephrine but did not reverse anisomycin inhibition of protein synthesis, as assessed by c-Fos immunohistochemistry. These findings are consistent with past evidence suggesting that anisomycin causes amnesia by initiating abnormal release of neurotransmitters in response to the inhibition of protein synthesis.     

Is the truth in the details? Extended narratives help distinguishing false “memories” from false “reports”

The present study examined the effects of fantasy proneness on false "reports" and false "memories", of existent and non-existent footage of a public event. We predicted that highly fantasy prone individuals would be more likely to stand by their initial claim of having seen a film of the event than low fantasy prone participants when prompted for more details about their experiences. Eighty creative arts students and 80 other students were asked whether they had seen CCTV footage preceding the attack on Swedish foreign minister Anna Lindh up to, and including, non-existent footage of the actual moment of the attack. If affirmative, they were probed for extended narratives of what they claimed to have seen. Overall, 64% of participants provided a false "report" by answering yes to the initial question. Of these, 30% provided no explicit details of the attack, and a further 15% retracted their initial answer in their narratives. This left 19% of the sample who appeared to have false "memories" because they provided explicit details of the actual moment of the attack. Women scored higher than men and art students scored higher than other students on fantasy proneness, but there was no effect on levels of false reporting or false "memory". Memories were rated more vivid and clear for existent compared to non-existent aspects of the event. In sum, these data suggest a more complex relationship between memory distortions and fantasy proneness than previously observed.     

Word fluency performance and strategies in children with cochlear implants: age‐dependent effects?

Löfkvist, U., Almkvist, O., Lyxell, B. & Tallberg, I.‐M. (2012). Word fluency performance and strategies in children with cochlear implants: age‐dependent effects? Scandinavian Journal of Psychology 53, 467–474. Word fluency was examined in 73 Swedish children aged 6–9 years divided into two age groups, 6–7 and 8–9 years; 34 deaf children with cochlear implants (CI) (15 girls/19 boys) and 39 age‐matched children with normal hearing (NH) (20 girls/19 boys). One purpose was to compare the ability to retrieve words in two different word fluency tasks; one phonemically based (FAS letter fluency) and one semantically based (animal fluency). A second purpose was to examine retrieval strategies in the two tasks by conducting an analysis of clustering and switching of word sequences. In general we found that age was an important factor for word fluency ability, in both the CI and the NH groups. It was also demonstrated that children with CI aged 8–9 years retrieved significantly fewer words and used less efficient strategies in the retrieval process, especially on the phonemically based task compared to children with NH of the same ages, whereas children 6–7 years performed similarly in both groups regarding number of retrieved words and use of strategies. The results are discussed with respect to factors such as age differences in performance for children with CI, especially for the phonemically based task.     

Research misconduct among clinical trial staff

Between 1993 and 2002, 39 clinical trial staff were investigated for scientific misconduct by the Office of Research Integrity (ORI). Analysis of ORI case records reveals practices regarding workload, training and supervision that enable misconduct. Considering the potential effects on human subjects protection, quality and reliability of data, and the trustworthiness of the clinical research enterprise, regulations or guidance on use of clinical trial staff ought to be available. Current ORI regulations do not hold investigators or institutions responsible for supervision and training of clinical trial staff. Given the important issues at stake, the definition of research misconduct should encompass the intentional or negligent mismanagement of scientific projects. Individual institutions and professional associations not only can but should adopt stricter standards of conduct than those reflected in federal regulations.     

Dark-adaptation mechanisms of the long-wave foveal cones

The ordinary long-term rod and cone dark-adaptation curves have generally been assumed to follow a single exponential rate of recovery. However, in two previous papers on rod dark-adaptation (Stabell et al., 1986a, b), the recovery curve was found to consist of three different sections. The results of the present paper show the same type of recovery function with three different sections for the long-term dark-adaptation curve of the long-wave cone system. During the major, middle section log cone threshold, like log rod threshold, is linearly related to the logarithm of the concentration of bleached photopigment. Presupposing that the bleached cone photopigment acts as a ligand, the change in threshold level obtained during the middle section of the dark-adaptation curve is well described by the change in activity rate of an allosteric, postively cooperative enzyme built as a dimer.     

Performance under simulated offshore climate conditions

An experimental study was set up simulating the environmental conditions and work load among drillers and maintenance personnel offshore. Thirty-six male subjects participated in the experimental study involving 3h exposures with dry gloves, wet gloves or without gloves. The subjects were working on tasks involving heavy and light muscle work, dexterity and cognitive tasks. Body and skin temperatures and heart rate variability were continuously monitored. Neuropsychological and endocrinological parameters were intermittently monitored. The data from the work performance tasks showed that motor functions, both gross and fine, were impaired when working with wet and, especially, without gloves. Working without gloves also affected mental work tasks. The neuropsychological and physiological data confirmed the work task studies: working with wet or without gloves led to increased tremor and impaired finger dexterity. Furthermore, reasoning was consistently impaired throughout the exposures compared with working with dry gloves. The heart-rate variability data and the endocrine results also showed a significant central nervous stress reaction for the two hypothermic conditions compared with the dry glove condition. Especially for drilling further north these data should imply that both health and performance may be detrimentally affected during working under such conditions with insufficient thermal protection.     

Problems in contemporary psychoanalytic theory: 1. Controversial issues

In two articles the controversial situation within contemporary psychoanalytic theory is discussed with reference to both the form and content of the theory. In the first article some areas of theoretical conflict between traditional drive theory, on the one hand, and object relations theory, self theory, and ego theory, on the other, are surveyed. It is concluded that inconsistency and ambiguity seem so penetrating that one can hardly speak of a unified theory of psychoanalysis at present. This seems to be a new situation in the history of psychoanalysis. A main issue of disagreement is that between drive theory and object relations theory concerning the nature of human motivation. In order to bridge the theoretical gap between the two positions, it seems necessary for psychoanalysis to disclaim the monolithic status of the drives and to adopt a broad theory of motivation where drives are only one contribution among several types of motivating forces. In the second article some lines of advance in psychoanalytic theory are discussed.     

Memory in schizophrenia and affective disorders*

The purpose of the present study was to investigate the stability of memory and information processing in schizophrenics and affectively disturbed patients. Twenty-two schizophrenics, eight affectives and 14 normal controls were tested twice, with an interval of approximately one year. Results showed that normals performed better than schizophrenics and affectively disturbed patients on almost all of the cognitive measures. The differences reached a level of significance on a reaction time test, a vigilance task and a long-term memory task. The only measure where the difference did not reach a level of significance was on a short-term memory test. Groups' performance to some extent changed over time on most of the measures, but the changes were not significantly different for different groups.     

Psychometric properties of the Social Problem Solving Inventory (SPSI) with normal and emotionally disturbed adolescents

The factor structure of the Social Problem Solving Inventory (SPSI; D'Zurilla & Nezu, 1990) was evaluated with a sample of 708 normal adolescents. Confirmatory factor analysis supported the empirically derived five-factor model reported by D'Zurilla and Maydeu-Olivares (1994) using an adult sample, but not the theoretically derived seven-factor structure of the original SPSI. The psychometric properties of the original and revised inventories are reported for normal adolescents and psychiatrically hospitalized adolescents (n=63). Internal consistency and reliability estimates were adequate. Support for the validity of the revised SPSI was demonstrated by examining the relationship between social skills, depression, and social problem solving; in addition, differences between normal and inpatient adolescent samples were examined. The findings are discussed in terms of the utility of the inventories with adolescents.
