Answer Sets and Qualitative Decision Making

Logic programs under answer set semantics have become popular as a knowledge representation formalism in Artificial Intelligence. In this paper we investigate the possibility of using answer sets for qualitative decision making. Our approach is based on an extension of the formalism, called logic programs with ordered disjunction (LPODs). These programs contain a new connective called ordered disjunction. The new connective allows us to represent alternative, ranked options for problem solutions in the heads of rules: A × B intuitively means: if possible A, but if A is not possible then at least B. The semantics of logic programs with ordered disjunction is based on a preference relation on answer sets. We show that LPODs can serve as a basis for qualitative decision making.     

Shedding Dialectical Tiers: A Social-Epistemic View

Is there a duty to respond to objections in order to present a good argument? Ralph Johnson argues that there is such a duty, which he refers to as the “dialectical tier“ of an argument. I deny the (alleged) duty primarily on grounds that it would exert too great a demand on arguers, harming argumentation practices. The valuable aim of responding to objections, which Johnson 's dialectical tier is meant to satisfy, can be achieved in better ways, as argumentation is a social-epistemic activity.     

Attitudes towards complementary and alternative medicine among medical and psychology students

The use of complementary and alternative medicine (CAM) is increasing in Europe as well as in the USA, but CAM courses are infrequently integrated into medical curricula. In Europe, but also especially in the USA and in Canada, the attitudes of medical students and health science professionals in various disciplines towards CAM have been the subject of investigation. Most studies report positive attitudes. The main aim of this study was to compare the attitudes towards CAM of medical and psychology students in Germany. An additional set of questions concerned how CAM utilisation and emotional and physical condition affect CAM-related attitudes. Two hundred thirty-three medical students and 55 psychology students were questioned concerning their attitudes towards CAM using the Questionnaire on Attitudes Towards Complementary Medical Treatment (QACAM). Both medical students and psychology students were sceptical about the diagnostic and the therapeutic proficiency of doctors and practitioners of CAM. Students' attitudes towards CAM correlated neither with their experiences as CAM patients nor with their emotional and physical condition. It can be assumed that German medical and psychology students will be reluctant to use or recommend CAM in their professional careers. Further studies should examine more closely the correlation between attitudes towards CAM and the students' worldview as well as their existing knowledge of the effectiveness of CAM.     

The Effect of Religious Short‐Term Mission Trips on Youth Civic Engagement

Religious short‐term mission trips are an increasingly popular form of American religious practice, especially among young people. Both organizers and participants often emphasize their transformative nature. However, scholarly efforts to evaluate systematically the social consequences of religious short‐term mission trips are lacking. To address this neglect, our article investigates whether going on a religious short‐term mission trip significantly differentiates youth who engage in civic actions from those who do not. Based on quantitative analysis of Wave I of the National Survey of Youth Religion (NSYR), we find that, controlling for other important factors, taking a mission trip significantly increases the likelihood of adolescents participating in various forms of civic activity, particularly religious‐based volunteer work. Drawing on prior scholarship on religious short‐term mission and similarly focused trips and in‐depth interview data from trip participants, we outline several theoretical mechanisms that likely explain the link between taking a mission trip and civic engagement.     

Acceptance and commitment therapy versus tinnitus retraining therapy in the treatment of tinnitus: a randomised controlled trial

The study compared the effects of Acceptance and Commitment Therapy (ACT) with Tinnitus Retraining Therapy (TRT) on tinnitus impact in a randomised controlled trial. Sixty-four normal hearing subjects with tinnitus were randomised to one of the active treatments or a wait-list control (WLC). The ACT treatment consisted of 10 weekly 60 min sessions. The TRT treatment consisted of one 150 min session, one 30 min follow-up and continued daily use of wearable sound generators for a recommended period of at least 8 h/day for 18 months. Assessments were made at baseline, 10 weeks, 6 months and 18 months. At 10 weeks, results showed a superior effect of ACT in comparison with the WLC regarding tinnitus impact (Cohen’s d = 1.04), problems with sleep and anxiety. The results were mediated by tinnitus acceptance. A comparison between the active treatments, including all assessment points, revealed significant differences in favour of ACT regarding tinnitus impact (Cohen’s d = 0.75) and problems with sleep. At 6 months, reliable improvement on the main outcome measure was found for 54.5% in the ACT condition and 20% in the TRT condition. The results suggest that ACT can reduce tinnitus distress and impact in a group of normal hearing tinnitus patients.     

The reproduction of intelligence

Although a negative relationship between fertility and education has been described consistently in most countries of the world, less is known about the relationship between intelligence and reproductive outcomes. Also the paths through which intelligence influences reproductive outcomes are uncertain. The present study uses the NLSY79 to analyze the relationship of intelligence measured in 1980 with the number of children reported in 2004, when the respondents were between 39 and 47 years old. Intelligence is negatively related to the number of children, with partial correlations (age controlled) of ?.156, ?.069, ?.235 and ?.028 for White females, White males, Black females and Black males, respectively. This effect is related mainly to the g-factor. It is mediated in part by education and income, and to a lesser extent by the more “liberal” gender attitudes of more intelligent people. In the absence of migration and with constant environment, genetic selection would reduce the average IQ of the US population by about .8 points per generation.     

Management der Parkinson-Demenz und Demenz mit Lewy-Körperchen

Idiopathisches Parkinson-Syndrom mit Demenz (PDD) und Demenz mit Lewy-K?rperchen (DLB) sind partiell unterschiedliche Manifestationen des Spektrums der Lewy-K?rperchen- und Alzheimer-Erkrankungen. Die Kombination von motorischer Parkinsonsymptomatik mit Demenz, affektiven St?rungen (Depression, Angst), Verhaltensst?rungen (wie REM-Sleep Behaviour Disorder) und psychotischen Episoden (Halluzinationen, Wahn, Delir) neben einer Reihe vegetativer Symptome und zunehmendem Nebenwirkungsrisiko erfordern eine ma?geschneiderte, sorgf?ltige, kombinierte Pharmakotherapie (L-Dopa mit Decarboxylasehemmer, gegebenenfalls Entacapone oder Tolcapone, neuere Antidepressiva wie SSRI, NaSSA, SNRI, Clozapin, Clonazepam, Therapie vegetativer St?rungen) und engmaschige klinische Kontrollen.     

Internet Versus Group Cognitive-Behavioral Treatment of Distress Associated With Tinnitus: A Randomized Controlled Trial

Tinnitus distress can be reduced by means of cognitive-behavior therapy (CBT), and the treatment can be delivered in different ways. The most recent format is Internet-based self-help. The aim of this study was to compare this treatment (n = 26) with standard group-based CBT (n = 25) in a randomized controlled trial. Outcomes on self-report inventories measuring tinnitus distress were evaluated immediately after and 1 year after treatment. Results showed that both groups had improved, and there were few differences between them. The effect size for the Internet treatment was d = 0.73 (95% CI = 0.16–1.30) and for the group treatment was d = 0.64 (95% CI = 0.07–1.21). The Internet treatment consumed less therapist time and was 1.7 times as cost-effective as the group treatment. At pretreatment patients rated the Internet treatment as less credible than the group treatment. In conclusion, Internet treatment for tinnitus distress merits further investigation, as the outcomes achieved are promising.     

Is it the sound or your relationship to it? The role of acceptance in predicting tinnitus impact

Tinnitus is an experience of sound in the absence of an appropriate external source. A symptom that can accompany most central or peripheral dysfunctions of the auditory system, tinnitus can lead to significant distress, depression, anxiety, and decreases in life quality. This paper investigated the construct of psychological acceptance in a population of tinnitus patients. First, a cross-sectional study (N = 77) was conducted in which a tinnitus specific acceptance questionnaire was developed. Results showed that a Tinnitus Acceptance Questionnaire (TAQ) generated good internal consistency. A factor solution was derived with two factors: activity engagement and tinnitus supression. Second, a longitudinal study (N = 47) investigated the mediating role of acceptance on the relationship between tinnitus distress at baseline and tinnitus distress, anxiety, life quality, and depression at a 7-month follow-up. The results showed full mediation of activity engagement for depression and life quality at follow-up, partial mediation for tinnitus distress, and no mediation for anxiety. The role of acceptance in the negative impact of tinnitus distress merits further investigation.
