In der Dissertation werden Fragen zur Populationsbiologie des neozonalen Nordamerikanischen Waschbären (Procyon lotor) behandelt. Die knapp sechsjährigen Freilanduntersuchungen fanden im Rahmen eines umfangreichen Waschbärenforschungsprojektes (www.projekt-waschbaer.de) in einem naturnahen Tieflandbuchenwald im Müritz-Nationalpark (Mecklenburg-Vorpommern) statt. Das Nationalparkgebiet wird nachweislich seit Ende der 1970er Jahre vom Waschbären besiedelt und stellt aufgrund seines Gewässerreichtums und seiner alten Laubbaumbestände einen idealen Lebensraum für Waschbären dar. Die Dissertation schließt die populationsbiologischen Arbeiten des Gesamtprojektes ab und stellt die Ergebnisse in fünf separaten Themenschwerpunkten vor (I. Raumverhalten, II. Sozialverhalten, III. Reproduktionsbiologie, IV. Populationsstruktur, V. Populationsdynamik). Übergeordnetes Ziel der Arbeit war die Erhebung valider populationsbiologischer Daten, um eine grundlegende ökologische Charakterisierung des Waschbären unter dem Aspekt des Natur- und Artenschutzes vornehmen zu können. Dazu wurden zwischen 2006 und 2011 in einem 1.114 ha großen Fallennetz im Serrahner Teilgebiet des Nationalparks an 53 verschiedenen Fallenstandorten 145 verschiedene Waschbären (62 ♀♀, 83 ♂♂) insgesamt 489 Mal gefangen, genetisch beprobt, vermessen und individuell markiert. 51 adulte Waschbären (23 ♀♀, 28 ♂♂) und 18 Jungtiere (10 ♀♀, 8 ♂♂) wurden darüber hinaus mit einem UKW-Halsbandsender ausgestattet und im Rahmen der telemetrischen Arbeiten insgesamt 31.202 Mal geortet (≙ im Mittel 452 Lokalisationen pro Tier). Im Kernuntersuchungsgebiet wurde an 36 beköderten Standorten ein Fotofallenmonitoring durchgeführt. Bei einer Überwachungsdauer von 5.365 Fotofallennächten entstanden dabei 18.721 Aufnahmen von 183 verschiedenen Waschbären. 82 % aller Waschbärenbilder zeigten individuell markierte Individuen. Alle 145 gefangenen Waschbären wurden im Rahmen eines separaten Teilprojektes mit hochvariablen Mikrosatelliten erfolgreich genotypisiert, so dass die Verwandtschaftsverhältnisse sowie der individuelle Reproduktionserfolg der Untersuchungstiere bekannt sind. Für die Analysen zur Populationsstruktur wurden unter anderem von 120 verendet aufgefunden Waschbären (Totfunden) aus dem unmittelbaren Umfeld des Nationalparks klassische morphometrische und phänotypische Merkmale sowie die Mortalitätsursachen erfasst. / This study considers questions concerning the spatial and social behaviour, reproduction, population structure and dynamics of the alien North American raccoon (Procyon lotor) in Germany. The investigations took place within the framework of a comprehensive raccoon research project (www.projekt-waschbaer.de) over a period of nearly six years in a close-to-nature lowland beech forest in the Müritz National Park (Mecklenburg-West Pomerania). The National Park has been verifiably colonized by raccoons since the end of the 1970s, and due to its abundance of water and its old deciduous tree population it represents an ideal habitat for this mammal. Between 2006 and 2011, 145 individual raccoons (62 ♀♀ and 83 ♂♂) were captured, genetically sampled, measured and individually tagged. Sampling took place within a 1,114 hectare area of the National Park, at 53 trap sites and with 489 trappings. 51 adult raccoons (23 ♀♀, 28 ♂♂) and 18 juveniles (10 ♀♀, 8 ♂♂) were also fitted with radio collars and located a total of 31,202 times as part of the telemetric survey (=452 localisations per individual). Camera trap monitoring was carried out at 36 baited locations of the main investigation area (1,628 ha): 18,721 camera trap pictures were taken of 183 different raccoons over a monitorring period of 5,365 nights. 82 % of all the raccoon pictures showed individually tagged ani-mals. All 145 of the trapped raccoons were successfully genotyped as part of a subproject with highly polymorphic microsatellites. Both the familial relationships and the individual reproductive success of the subject animals could be determined with the genotyping results. For the analyses of the population structure, classic morphometric and phenotypical characteristics, as well as the cause of mortality of 120 raccoon carcasses in the immediate vicinity of the National Park, were recorded.

Autismus-Spektrum-Störung (ASD) ist eine neurologische Entwicklungsstörung, die durch eine Reihe von Entwicklungsstörungen gekennzeichnet ist, die zu einem Mangel an sozialen, kommunikativen und kooperativen Fähigkeiten führen. Sozio-kommunikative Beeinträchtigungen können durch von Verhaltenstherapeuten konzipierte und durchgeführte Trainingsprogramme für soziale Kompetenzen verbessert werden. Computergestützte Therapien zur Lösung sozio-kommunikativer Schwierigkeiten bei Kindern, Jugendlichen und Erwachsenen mit ASD haben ermutigende Ergebnisse gezeigt. Das Serious-Game-Format ist eine Form der Intervention. Seriöse Spiele sind pädagogisch wertvoll, aber oft attraktiver als offensichtliche pädagogische Hilfsmittel. Zirkus Empathico 2.0 ist ein Serious Game für mehrere Spieler mit verschiedenen Levels und Bühnen in einer Zirkusumgebung. Die Auswertung erfolgte über einen Zeitraum von acht Wochen. Sechzig Kinder mit ASD im Alter von fünf bis elf Jahren wurden vor und nach der Behandlung untersucht. Zu den primären Ergebnissen gehörten die Empathiebewertung durch die Eltern und objektiv gemessene Fähigkeiten zur Emotionserkennung. Die Bewertung der Effektivität und Verwendbarkeit des Spiels für das Training sozialer Kompetenzen zeigte, dass es eine plausible Lernumgebung schuf, indem es das Bewusstsein der Studienteilnehmer für Fähigkeiten und neurotypisches Verhalten steigerte und ihre vorhergesagte Angst in zukünftigen sozialen Situationen verringerte. Nach der Behandlung wurden signifikante Behandlungseffekte festgestellt. Sowohl bei Kurz- als auch bei Langzeitbeurteilungen. Zirkus Empathico 2.0 ist erfolgreich bei der langfristigen Verbesserung der sozio-emotionalen Fähigkeiten in realen Situationen. Zukünftige Forschung sollte sich auf die spezifischen Prozesse konzentrieren, die den Übertragungs- und Aufrechterhaltungsvorteilen von Empathie und Emotionserkennung zugrunde liegen. / Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by a spectrum of developmental abnormalities that result in a lack of social, communicative, and collaborative abilities. Socio-communicative impairments can be improved through behavioral therapist-designed and delivered social-skills training programs. Computer-based therapies to resolve socio-communicative difficulties in children, adolescents, and adults with ASD have demonstrated encouraging outcomes. The serious game format is one type of intervention. Serious games are educational but often appeal more than overt pedagogical tools. Zirkus Empathico 2.0 is a multi-player serious game set with various levels and stages in a circus environment. It was evaluated over eight weeks. Sixty children with ASD aged five to eleven years were evaluated before treatment and post-treatment. Primary outcomes included empathy rating by parents and objectively measured emotion recognition abilities. Secondary outcomes were assessed as emotional awareness, emotion management, well-being, and personal therapy goals. The assessment of the game's effectiveness and usability for social-skills training indicated that it established a plausible learning environment by boosting trial participants' awareness of abilities and neurotypical behavior and decreasing their predicted fear in future social situations. Following treatment, significant treatment effects were detected. In both short- and long-term assessments, moderate impacts were observed on emotional awareness, emotion management, and autistic social symptomatology. Parents reported that therapy goals were met, and that treatment was transferred well. Zirkus Empathico 2.0 is successful at improving long-term socio-emotional abilities in real-world situations. Future research should focus on the specific processes behind empathy and emotion recognition's transmission and maintenance benefits.

The main aim of the present study was to explore the relationship between parenting styles, as used by the pre-school parent and the social behaviour of the five-year old. Specific attention was given to three main parenting styles: authoritative, authoritarian and permissive. The eight developmental perspectives applicable for the five-year old were also discussed. The research was conducted according to the quantitative approach. The Parental Styles Dimensions Questionnaire (PSDQ) was completed and returned by a sample of 30 parents (N=30) from Evergreen Pre-primary in Gauteng. The representative sample of five-year olds being observed by the teacher were 24 pupils (N=24). The teacher rated the five-year olds' behaviour using the Behavioural Questionnaire (BQ). These results indicated primarily that the Authoritative Parenting Style was most used by the parents of the five-year old group and that this Parenting Style tends to lead to more acceptable social behaviour among the five-year olds. / Social Work / M.

Truancy is one of the problems that exist in schools and affect learners' performance. The aim of the current study was to determine how truancy manifests and also to explore the life world of truants in secondary schools. From the literature review, the two types of truancy, namely blanket truancy and post-registration truancy were described. Various programmes and approaches used in truancy intervention were explored. An empirical investigation was undertaken with a sample of 758 Grade 10 learners from three secondary schools. The results indicated that significantly more males than females engaged in truancy. There is also a significant dependency between learning problems and truancy. The results of the study were analysed and recommendations for intervention and for further study were made. / Educational Studies / M.Ed. (Guidance and Counseling)

Text in Afrikaans / This study, which was undertaken within a qualitative and quantitative methodological framework, is a collaborative action research project that focuses on the impact of emotional intelligence (EI) teaching in the classroom as intervention to prevent the inappropriate behaviour of learners that could lead to violence and crime. The study also concentrates on how action research can enhance the educator’s teaching practices. The objective was to prevent learners from misbehaving by implementing EI as a teaching strategy in the classroom on the basis of various definitions and models of EI. This research project also explored the coordinated and integrated management of positive learner behaviour, overall school development and the management of a culture of positive behaviour. The empirical study concludes that there is a correlation between EI teaching methods and learners’ behaviour. In view of the fact that the use of EI in the classroom can prevent the inappropriate behaviour of learners it can therefore be regarded as preventative discipline. / Psychology / M.A. (Sielkunde)

The purpose of this study was to investigate the misconduct of learners in secondary schools in the Ntoane village. It served to determine the • extent to which teenage fall pregnant; • the intensity in which teachers tackle gender violence in schools; • the manner in which the parents’ culture and values are enforced by the teachers. Recommendations are made on how to overcome these barriers and to improve the level of misconduct. A literature study was carried out to gain an understanding of misconduct, and covered the following issues: • What is misconduct? • The causes of misconduct. • An overview of learner misconduct. • The origins of learner misconduct. • Manifestations of learner misconduct in the classroom. • The factors which cause learner misconduct. A qualitative research method was used in this research. The targeted population groups are teenagers in grades 9 and 10 in the Ntoane village. v Interviews were conducted at two schools in the Ntoane village where educators, the school governing bodies and members of the representative council of learners were interviewed. The findings were discussed at length to determine the research objectives. Conclusions were drawn after analysing these findings, and recommendations were formulated. / Education Management / M. Ed.

The MA Social Behaviour Studies in HIV and AIDS as a postgraduate degree requires students to work and conduct research independently. The purpose of the study was to gauge the perceptions, attitudes and experiences of second year students and key personnel concerning student support. A mixed methods research design was used. It was found that students and staff regarded support in a positive light, although concerns about insufficient resources were expressed. Students expressed needs for specific academic and research support. Staff tended to romanticise the reasons for students enrolling for the degree. Possible conflicting expectations of the degree and the amount and type of support offered were found between the staff and the students and also among various staff members. / Social Work / M.A. (Social Behaviour Studies in HIV-AIDS)

This study deals with the problem of moral development discontinuity prevalent in today's multicultural societies. Black adolescents are confronted by many obstacles in their situatedness in the home, school and society. It has been revealed that the black adolescent in the multicultural situation is exploited, dehumanised and exposed to impersonal situations when he should be offered moral guidance and challenging moral dilemmas in order to develop his moral sense, however he is consequently reduced to an object that is tossed to and fro by his fellow human beings. The black adolescent, it has been shown, needs his fellow human beings, as transmitters of moral values to help him to achieve a moral-self. This study examines the three multicultural situations, the home, the school and the society and shows that morals are not inherited but acquired through mutual contact. The acquisition of morals manifests itself under conditions characterised by respect, modelling, imitation, indoctrination, reward and punishment, conformity, loyalty, communication, exemplification, socialisation, experience and learning as determined by the home, school and society. It was also found that in their acquisition of morals in a multicultural society, black adolescents experience confusion brought about by the cultural differences of their society. \\!hat they previously regarded as the right thing to do in their cultural background receives negative responses in the multicultural situation. It was further found that black adolescents in a multicultural situation are not provided with sufficient opportunities to participate meaningfully in moulding their new moral environment. The multicultural environment is cold and unfriendly, as a result black adolescents are barred from expanding and anchoring themselves in their new situation to face the challenges confronting them with confidence. The empirical research revealed that in the home parents are too busy with their professional upgrading and the positions they hold at work to bother about the moral upbringing of their children. In school teachers emphasise scholastic achievement above moral development. The society does not provide black adolescents with moral role models to imitate. Society has become to technocratic, with devices such as the TV, radio, Internet and video games, to guide black adolescents in their moral intemalisation. / Psychology of Education / D. Ed.

Hazing is a universal practice. The process is multi-dimensional and includes both positive and negative aspects. Hazing broadly refers to the negative aspects of what newcomers experience as they integrate into a group. This study focuses on hazing during orientation programmes for Grade 8 boys in monastic secondary schools in South Africa. The problem was investigated by a literature study and a survey using a self-designed questionnaire. It was completed by a non-probability sample of 296 Grade 12 boys from three selected schools in Gauteng Province. Data measured the biographical attributes of respondents and determined their opinions of activities engaged in during the orientation programmes. Findings indicated that respondents were positive about the orientation programme which acts as an introduction into secondary school and is a means whereby traditions are transmitted. Respondents were very opposed to any injurious activity. The objectives of orientation programmes are well-grounded but when they deteriorate into hazing, they are very negatively perceived. / Educational Studies / M. Ed. (Comparative Education)

Thesis (PhD) -- Stellenbosch University, 1990. / ENGLISH ABSTRACT:Bushpig sociology, energetics, reproduction and population dynamics were studied over an 8-year period in the Cape Province, South Africa. The social organization was found to be strikingly different from that known from other suid species. The basic social unit is a unimaternal family group, occupying a resource-based territority, with a monogamous mating system. This form of social organisation is related to the dispersed nature of food resources, to which it provides exclusive access. It is reminiscent of canid social systems. Agonistic behaviour, communication and maternal behaviour were studied as the opportunity arose. The average home range size was 7,2 kmª, ranging from 3,8 to 10.1 kmª. Home ranges were often traversed within 1-4 days, as part of territory patrolling. The average diel ranging distance was 3 km. Bushpig were active during both night and day and exhibited a basic bimodal rhythm. The main phase of intensive foraging occurred from before dusk to midnight, with a secondary activity peak after dawn. Activity schedules were geared to avoid extreme ambient temperatures. Temperature regulation and water use were investigated, with particular reference to thermoregulatory behaviour (nest building). pelage characteristics, body core temperature dynamics, thermoneutral zones and resting metabolic rates. The thermoneutral zone for 10 kg bushpig juveniles was estimated to lie between 13° and 30°C and that for adults between 8° and 25°C. Foraging behaviour, diet and its nutritient content were investigated. Regional differences in the nutritional quality of bushpig diets in the Eastern and Southern Cape were associated with the predominance of nutrient-rich and nutrient-poor substrates respectively. These in turn were reflected by divergent life history features in the populations from the two regions. Patterns of growth and energy storage were described and the value of various parameters (e.g. mass to size ratio, fat depositions, blood composition) to evaluate condition was investigated. In studying reproductive biology, sexual maturation, female reproductive cycles, prenatal litter statistics, foetal development, 1actation, breeding seasonality and reproductive turnover were the main aspects addressed. The role of food quality, body condition and social status in determining reproductive success was discussed. Bushpig population density estimates in the Southern Cape ranged between 0,3 and 0,5 animals/kmª• The dynamics of Southern and Eastern Cape populations were found to differ. The differences are consistent with the hypothesis that social organisation is determined by the distribution and availability of food while diet quality shapes life history tactics. A life history model was developed which links edaphoclimatic environmental conditions with diet quality, metabolic turnover rate and, ultimately, life history features. In the concluding chapter some of the managerial implications of the research findings are discussed. / AFRIKAANSE OPSOMMING:Die sosiologie, fasette van die energiebalans (temperatuurregulasie, voeding). voortplanting en bevolkingsdinamika van bosvarke is in die Kaapprovinsie (Suid-Afrika) oor 'n tydperk van 8 jaar bestudeer. Dit kon bewys word dat die sosiale organisasie van die bosvark van die van ander varksoorte verskil. Die basiese sosiale eenheid bestaan uit 'n familiegroep wat slegs 'n enkele telende moederdier bevat. Ruimtelike organisasie is gebaseer op 'n stelstel van voedingsterritoriums. 'n Monogamiese paringstelsel kom voor. Die yl verspreiding van voedsel word as die onderliggende rede vir die sosiale organisasie beskou. Gedragspatrone (kommunikasie, aggressie, grootmaak van kleintjies) is bestudeer soos die geleentheid voorgekom het. Heelwat ooreenkomste is gevind tussen die sosiale organisasie van die bosvark en lede van die hondefamilie. Die gemiddelde woongebiedgrootte is 7,2 kmª (tussen 3,8 en 10,1 kmª). Woongebiede word gewoonlik binne 1-4 dae deurkruis en dus soos territoria gepatroleer. Die gemiddelde daaglike bewegingsafstand was 3 km. Bosvarke was beide gedurende die nag en die dag aktief en het 'n bimodale aktiwiteitsritme gevolg. Die hoofaktiwiteitsfase van intensiewe voeding het tussen sononder en middernag plaasgevind, met 'n sekondere fase na sonop. Soedoende is temperatuuruiterstes vermy. Temperatuurregulasie en watergebruikpatrone is bestudeer, insluitend temperatuurreguleringsgedrag, haarkleedeienskappe, liggaamskerntemperature, termoneutraliteit en metabolise omset. Voedingsgedrag, voedsel en die voedingswaarde daarvan is ondersoek. Verskille tussen die Oos- en Suid-Kaap in die kwaliteit van voedsel hang saam met die laer vlak van voedingsstowwe in die gronde van die Suid-Kaap. Bosvarkbevolkings in die twee streke toon verskille in populasiedinamika wat hieraan toegeskryf kan word. Groei- en energiestoorpatrone is beskryf. Die moontlikhede is ondersoek om kondisie te evalueer met behulp van parameters soos massa tot grootte-verhoudings, vetneerleggings en bloedwaardes. Aspekte van voortplantingsbiologie, soos geslagsrypheid, vroulike voortplantingssiklusse, voorgeboortelike werpselgroottes, foetale ontwikkeling, laktasie, seisoenaliteit en voortplantingsomset is behandel. Die rol van voedselkwaliteit, kondisie en sosiale status by die bepaling van voortplantingsukses word bespreek. Skattings van die bevolkingsdigtheid van bosvarke in die Suid-Kaap het gewissel tussen 0,3 en 0,5 diere per kmª• Op grond van die verskille in bevolkingsdinamika tussen bosvarke in die Suid- en Oos-Kaap is 'n model ontwikkel om die verband tussen bevolkingsregulering en lewensstrategieeë (life history tactics) te verklaar. Hiervolgens het voedselbeskikbaarheid die tipe sosiale organisasie bepaal terwyl die lewensstrategieë van bevolkings die gevolg is van voedselkwaliteit. Die model stel vaar 'n verband tussen groeipleksomstandighede, voedselkwaliteit, metaboliese omset en bevolkingsdinamika. In die laaste hoofstuk word sommige van die bestuursimplikasies van die navorsingsbevindinge bespreek.
