Self-awareness (svasa?vedana) and Infinite Regresses: A Comparison of Arguments by Dign��ga and Dharmak��rti

This paper compares and contrasts two infinite regress arguments against higher-order theories of consciousness that were put forward by the Buddhist epistemologists Dign??ga (ca. 480?C540 CE) and Dharmak??rti (ca. 600?C660). The two arguments differ considerably from each other, and they also differ from the infinite regress argument that scholars usually attribute to Dign??ga or his followers. The analysis shows that the two philosophers, in these arguments, work with different assumptions for why an object-cognition must be cognised: for Dign??ga it must be cognised in order to enable subsequent memory of it, for Dharmak??rti it must be cognised if it is to cognise an object.     

A radiographic assessment of pediatric fracture healing and time since injury

Past studies and pediatric bone physiology indicate that younger individuals may heal at a faster rate. Additionally, in adults upper limb fractures heal faster than lower limb fractures; this trend is expected for pediatric fractures. This study aims to evaluate and compare rates of fracture repair in children based on age and skeletal element. Six stages are used to describe the bone repair process in 294 radiographs of tibial and radial fractures from 107 infants and young children. Healing rates are examined using ANOVA and Welch's t-test with a 95% confidence interval. Results indicate that younger individuals spend less time at stage 1, suggesting a delay in the start of healing. Furthermore, forearm fractures heal faster than leg fractures at stages 2 and 3, suggesting a role in the osseous reaction of bone healing. The healing schedule presented may allow the timing of injuries to be estimated from radiographs.     

Children's eyewitness identification performance: Effects of a Not Sure response option and accuracy motivation

Purpose. Children who witness crimes are sometimes asked to view a photospread lineup to see if they can identify the culprit. Here, we examined the effectiveness of two manipulations designed to assist in overcoming the tendency of child eyewitnesses to choose from lineups, a tendency that manifests in false identifications from target‐absent lineups. Methods. Children aged around 12 years (N = 432) were randomly assigned to control, Not Sure, or accuracy motivation conditions in order to examine both target‐absent and ‐present identification test performance across multiple sets of stimulus materials. Results. The Not Sure option did not affect false alarms or hit rates, but the combination of accuracy motivating conditions and the Not Sure option reduced guessing, with overall rates of false identifications falling by 12.2%. The latter effect was much stronger under some stimulus conditions but not detectable under others, indicating that the manipulations could improve but not impair performance. While there were beneficial effects at the group level, the manipulation did not produce a general change in individual children's decision strategies. Conclusions. Eyewitness identification test manipulations that reliably reduce false alarms, without lowering hits, by child witnesses have not yet been identified. Here, we showed how a simple‐to‐implement accuracy motivation manipulation reduces false alarms under some conditions, while also highlighting the importance of evaluating the efficacy of interventions across varied encoding and test conditions. However, developing a procedure that can produce a generalized improvement in decision making at the individual level remains a major challenge for eyewitness researchers.     

The asymmetrical remodelling of two neurosurgical burr holes: a case study

A human skull identified as that of a 16-year-old female who had been reported missing about 3 years before the discovery of the specimen displayed evidence for the asymmetrical remodelling of bilateral neurosurgical burr holes. While one of the holes retained its original size and shape, gross evidence for the contralateral lesion had virtually disappeared. Initially, the open lesion was mistakenly suspected to be a recent bullet hole.     

Die sozialen Konsequenzen der Restitution von Grundeigentum in Deutschland und Polen

Der Artikel vergleicht die Restitution von Immobilieneigentum in Polen und Deutschland. In Polen gibt es bisher keine gesetzliche Regelung, aber über Verwaltungsentscheidungen wird dennoch Privateigentum restituiert; in Deutschland ist der Restitutionsprozess weitgehend abgeschlossen. Die Analyse geht der Frage nach, ob die moralisch und funktional begründete Privatisierung ihre vorgegebenen Ziele erreicht hat. Die Privatisierung von Häusern und Grundstücken greift in einen sensiblen, mit persönlichen Emotionen verquickten Bereich der Sozialordnung ein, so dass die doppelte Zielsetzung der Restitution, sowohl historische Gerechtigkeit als auch kapitalistische Marktverhältnisse herzustellen, besonderen Schwierigkeiten begegnet. Die Analyse der sozialen und ökonomischen Konsequenzen der sehr unterschiedlich gestalteten Prozesse zeigt, dass in beiden Gesellschaften das anspruchsvolle Ziel einer Herstellung historischer Gerechtigkeit nicht ohne die Entstehung neuer sozialer Ungleichheiten und Ungerechtigkeiten umgesetzt werden konnte. An den Beispielen Prenzlauer Berg und Kleinmachnow in der Region Berlin werden große Unterschiede in der Akzeptanz der Rückgabe durch die Betroffenen deutlich.     

Metabolism and toxicological detection of the designer drug N-(1-phenylcyclohexyl)-3-methoxypropanamine (PCMPA) in rat urine using gas chromatography-mass spectrometry

Studies on the metabolism and the toxicological detection of the phencyclidine-derived designer drug N-(1-phenylcyclohexyl)-3-methoxypropanamine (PCMPA) in rat urine are described using gas chromatographic-mass spectrometric (GC-MS) techniques. Based on the identified metabolites, the following metabolic pathways could be postulated: N-dealkylation, O-demethylation partially followed by oxidation of the resulting alcohol to the corresponding carboxylic acid, hydroxylation of the cyclohexyl ring at different positions, and aromatic hydroxylation. The formed metabolites were identical to those of the homologue N-(1-phenylcyclohexyl)-3-ethoxypropanamine (PCEPA) with exception of the mono hydroxyl metabolites of PCEPA. All PCMPA metabolites were partially excreted in conjugated form. An intake of a common drug users' dose of PCMPA could be detected in rat urine by the authors' systematic toxicological analysis (STA) procedure using full-scan GC-MS after acid hydrolysis, liquid-liquid extraction and microwave-assisted acetylation. The STA should be suitable for proof of an intake of PCMPA also in human urine assuming similar metabolism.
