Magister Commercii (Industrial Psychology) - MCom(IPS) / The current crime rate in the Western Cape plays a crucial role in the exposure of police officers to stressful and traumatic events. The intensity and frequency of this exposure, if not treated, could lead to police officers experiencing comorbid disorders such as post-traumatic stress disorder (PTSD). This leads to an increased need for trauma intervention strategies to be offered, to assist police officers who are exposed to trauma in the South African Police Service (SAPS). Although trauma intervention programmes are established within SAPS, a difference in perception about their effectiveness and service offering are presented. The purpose of this study was to investigate the differences in perception toward stress and trauma intervention strategies within the SAPS in the Western Cape. In order to achieve the purpose of the study, the researcher, tapped into the lived experiences of current police officers and Employee Health and Wellness (EHW) staff, employed by SAPS through semi-structured interviews. Through a comparative design, the study will add value to the current body of knowledge, as differences and similarities between two of the primary role players in the trauma debriefing process within the SAPS are explored. The research sample, recruited by means of convenience sampling, consisted of seven EHW staff members who had experience with dealing with stress and trauma-related programmes, and eight visible policing police officers who had experienced some form of trauma-related incident. The researcher made use of an in-depth interview guide as the research instrument for this study, which consisted of audio-recorded semi-structured interviews with the participants. The audio recordings were transcribed, and then analysed by means of thematic analysis. The findings showed that a difference in perception exists between police officers and EHW staff members toward the effectiveness of trauma intervention strategies offered in the SAPS. The findings also suggest that the majority of police officers do not make use of the trauma intervention programmes in the SAPS, in comparison to EHW staff reporting on good attendance by police officers at the service offerings. Similarities in perception between the two groups presented itself in the form of how trauma is defined, the different responses to trauma and coping mechanisms employed by police officers. The implications of this study include a contribution toward policy and structural amendments of the Employee Assistance Programme (EAP) framework within the SAPS, as well as a motivation for implementing a compulsory trauma counselling programme for police officers.

Rapporten innehåller analysen av 26 olika situationer inom ishockey. Situationerna är hårda tacklingar från olika matchar och ligor. Analyserade tacklingar resulterade INTE i hjärnskakning, likadana situationer kan ge upphov till hjärnskakning. Målet med projektet är bland annat skapa en kontrollgrupp för studierna i hjärnskakning inom ishockey. Tidigare studier utfördes för situationer som resulterar i hjärnskakningar. Rapporten pekar kort på huvudet och nackens anatomi d.v.s. skalp, hjärnan och skallben. Begreppet hjärnskakning med dess symptom förklarades också. I valda video sekvenserna analyserades huvudets kinematik och kollisionssekvenser mellan huvud och den andra parten som kan vara en annans axel, huvud, arm eller is eller glasvägg(plexiglas). Resultatet ska komma överens med tidigare gjorda arbete. / The report includes analysis of 15 different situations in Ice-hockey. The situations are hard tackles from different matches and leagues. The analyzed tackles did Not resulted to concussion, but similar situations can be concussions. The goal of the project includes creating a control group for the studies of concussions in ice-hockey. Previous or parallel studies have been down to situations that result to concussions. The report indicates short to head and neck anatomy that is scalp, brain and skull. The concept of concussion with its symptoms explained in this report. The selected video sequences were analyzed head kinematics and collision sequences between the head and the other part that may be another person's shoulder, head, arm or ice or glass wall. When the video sequences were analyzed attempted to controll the head speed, head acceleration and the tackles angle. The results should agree with previous works.

Thesis deals with sexual abuse. Theoretical part defines sexual abuse first, describes forms, perpetrators and victims. The next step is description of sexual abuse as a traumatic event and traumatic process. Short-term and long-term consequences are discussed. Empirical part deals with specific phenomenon in adult's life with experience of sexual abuse. Grounded theory and case studies are used to find specific areas of interest in sexually abused persons. Results find several phenomenon in adult's life of sexually abused persons.

The relation between dissociative symptoms and posttraumatic stress disorder (PTSD) was investigated in women who had experienced trauma or sexual assault. Subjects were administered the Dissociative Experiences Scale (DES), the Sexual Experiences Scale (SES), and the PTSD Interview (PTSD-I). Subjects were grouped according to their scores on the SES and the PTSD-I. Analysis of variance revealed a relation between DES scores and PTSD symptom severity scores. Correlational analyses showed a relation between dissociative symptoms and PTSD symptom severity but not recency of trauma. Three factors from a previously published factor analysis of the DES were found to contribute to the DES scores of PTSD subjects.

American children growing up in poor urban communities experience a disproportionate amount of direct and indirect violence in addition to the challenges of growing up with limited resources. Due to high amounts of physical and structural violence in these communities, urban youth are at increased risk for complex post-traumatic stress disorder (C-PTSD) and its associated sequelae, such as asthma, obesity, diabetes, and behavioral problems. Evidence demonstrates that sexual abuse and repeated interpersonal trauma leads to more intense symptomatology than traditional post-traumatic stress disorder (PTSD), and traumatic events in early childhood predisposes one to a C-PTSD reaction. This literature review of complex trauma serves to further validate the need for modern psychiatry to recognize C-PTSD as a diagnosis and to identify treatment interventions for this vulnerable population. / Urban Bioethics

Recently there has been considerable attention directed towards the increased risk for head injuries that athletes face while participating in high impact sports. Furthermore, there is also heightened interest in the asymptomatic sport related sub-concussive blows, commonly experienced during play, that possibly lead to long term neurological deficits. Purpose: The goal of this study was to investigate retired professional athletes of the Canadian Football League with a history of sport-related concussions, using several advanced MRI methods. The ultimate goal being the identification of any potential synergistic effects between a history of sport-related concussions, and exacerbated cognitive decline later on in life. Materials and Methods: Twenty former professional athletes of the Canadian Football League were scanned using a GE Discovery MR750 3T MRI with a 32-channel RF-coil. Axial FSPGR-3D images were used to define rs-BOLD and DTI scans. Seed based network analysis of the DMN was performed on rs-BOLD data. Voxel-wise tensor fitting of DTI data provided the means for estimating several tensor metrics. Results were normalized through comparison with a database of healthy controls. Potential associations between functional connectivity, white matter integrity, and cortical thickness measures were correlated with retired athlete position and years of professional play. Results: We found widespread cortical thinning in retired CFL subjects, alongside significant increases in axial and mean diffusivity in the corona radiata and splenium and genu of the corpus callosum compared to controls. Seed based correlation analysis of the DMN network revealed interrupted connectivity in retired athletes. Athlete age, po- sition, and number of years played appear to be factors in overall core white matter microstructural integrity. Conclusions: When compared to an age and sex matched control population, differences were observed both in functional and structural con- nectivity, suggesting that even years after retiring the brains of these former athletes still exhibit signs of damage. / Thesis / Master of Applied Science (MASc) / Sport-related concussions affect millions of athletes on a yearly basis in the United States alone. Concussions are often accompanied by short-lived neurological impairments, such as confusion, headaches, dizziness, nausea and memory loss. In addition, there is the potential for development of long term mental health and cognitive impairment. The goal of this work was to identify any neurological changes present in retired athletes of the Canadian Football League, through the use of advanced magnetic resonance imaging techniques evaluating thickness of brain structures, changes in brain activity, and alterations in core microstructure of the brain. Analyzing the results of these techniques revealed changes in a number of brain regions within the retired professional athlete population. These results suggest that a career of high impact sports may lead to short term, in addition to long-term neurological consequences.

Abortion can be a significant event in a woman's life. Some women are found to be affected by severe negative psychological complications following abortion. A synthesis of the current research on post abortion grief and support implications was conducted for this literature review. Those women who have ineffective coping post abortion were described to have dysfunctional grief. The uniqueness of the loss and the stigma attached to abortion, which has prevented women from seeking help, contributes to the dysfunctional grief. Screening and assessment of women have been found to be beneficial in identifying those who were suffering. Validation of the feelings that women ' express has been cited in the literature as one of the most significant supportive interventions that can be provided to women who are coping ineffectively. Education can be helpful in guiding nurses, practitioners, and students to evaluate, and provide support for women who are grieving ineffectively, thus initiating healthy grieving in this population. The implications for nurses to assess for pregnancy loss, educate and promote healthy grieving in women are supported by this literature review.

Mammalian brain is challenging to study due to its heterogeneity and complexity. However, recent advances in molecular imaging, genomics and proteomics have contributed significantly to achieve insights into molecular basis of brain function and pathogenesis of neurological disorders. Efficient sample preparation is an integral part of a successful mass spectrometry (MS)-based proteomics. Apart from the identification, quantification of proteins is needed to investigate the alterations between proteome profiles from different sample sets. Therefore, this thesis investigates optimizing and application of the MS compatible sample preparation techniques for the identification and quantification of proteins from brain tissue. The central objective of this thesis was (i) to improve the extraction of proteins as well as membrane proteins (MPs) from the brain tissue and (ii) to apply the optimized method along with the stable isotope dimethyl labeling (DML) and label-free (LF) MS approaches for the relative quantification of the brain proteome profiles during neurological conditions such as Alzheimer’s disease (AD) and traumatic brain injury (TBI).  First study described in this thesis is focused on the qualitative aspects for the brain tissue sample preparation. The optimized extraction buffers from first study containing n-octyl-β-glucopyranside or triton X-114 were used in the further quantitative studies to extract the proteins from patient (AD or TBI) and control human brain samples. Triton X-114 has additional advantage of separating MPs into a micellar phase. Therefore we also investigated the possibility to apply this in combination with DML quantitation approach for enrichment of low abundant MPs from AD brains. AD and TBI causes severe socio-economic burden on the society and therefore there is a need to develop diagnostic markers to detect the early changes in the pathology of the disease. Analytical tools and techniques applied and discussed in this thesis for neuroproteomics applications proved to be powerful and reliable for analyzing complex biological samples to generate high-throughput screening and unbiased identification and quantitation of disease-specific proteins that are of great importance in understanding the disease pathology.
