Mentally ill accused in South African criminal procedure: evaluating the mental health court model as therapeutic response

Pienaar, Letitia 11 1900 (has links)
Mental illness that affects an accused’s fitness to stand trial is an ill-explored topic in the South African criminal justice system. The necessity to explore this topic is motivated by the increasing number of persons with mental illness moving into the criminal justice systems in South Africa, Canada, and the United States of America. An accused’s fitness to stand trial is assessed once concern about his ability to follow the proceedings, or give proper instructions to his legal representative, is in doubt. The assessment is conducted in the forensic system where the vastly different fields of law and psychiatry meet. The South African forensic system is plagued with resources and skills shortages. These inadequacies cause delays in resolving pre-trial issues for an accused in respect of whom fitness is at issue. The accused is oftentimes detained in a correctional facility awaiting fitness assessment for anything between three months to two years. Generally, detention in a correctional facility has a negative effect on the mental state of a person with a mental illness. The logistics of fitness assessments differ between the three jurisdictions referred to above. However, the threshold for fitness in these jurisdictions is relatively low, with the result that the majority of accused persons sent for fitness assessments are found fit to stand trial. Such a finding does not imply that the accused is not mentally ill; it simply means that the illness does not affect his understanding of the court proceedings and that it does not influence his ability to communicate with his legal representative. An accused with a serious mental illness such as schizophrenia or major depression can, for example, be found fit to stand trial. After a fitness assessment, a court may either find an accused fit to stand trial or unfit to stand trial. The fact that many persons found fit to stand trial have a mental illness suggests that there is a third category on the fitness continuum that must be acknowledged, namely, fit but mentally ill accused persons. No alternatives to traditional prosecution currently exist in South Africa for this third group of accused persons despite the fact that their situation in the criminal justice system calls for a therapeutic response. The South African legislative framework that regulates fitness assessments and the processes associated therewith are not without challenges. The assessment practices have recently been under scrutiny by the Constitutional court, which judgment changed the position for the accused found unfit to stand trial. The position of the fit but mentally ill accused remains unregulated. The Canadian and American criminal justice systems have implemented diversion programmes for fit but mentally ill accused persons in the form of Mental Health Courts. The underlying principle of a Mental Health Court is therapeutic jurisprudence. Therapeutic jurisprudence evaluates the impact of the law on those in conflict with it. It promotes the inclusion of expertise from other disciplines to improve the effectiveness of the law in a particular set of circumstances. Many South African scholars acknowledge the need for mental health expertise in the criminal justice system, and suggestions have been made for the diversion of mentally ill accused persons charged with minor offences. Those above notwithstanding, no formal diversion programmes exist in South Africa for the fit but mentally ill accused. This research investigates the Mental Health Court as a therapeutic response to the mentally ill accused in the South African criminal justice system. The Mental Health Court models as employed in Canada and the United States of America are studied to identify elements thereof that can be employed in the South African context to provide an effective alternative to traditional prosecution for the mentally ill accused. The Toronto Mental Health Court is studied in the Canadian context as a court that is not a diversion programme as such but has a diversion component attached to it. Diversion in Canada is reserved for those charged with less serious offences, and only these accused persons are allowed into the diversion component of the Mental Health Court. However, the Canadian Mental Health Court assists those who do not qualify for diversion but who need the specialised skills of the Mental Health Court for purposes of, for example, a bail application. The Brooklyn Mental Health Court in the United States of America is investigated as a model that constitutes a complete diversion programme and considers diversion of accused persons charged with more serious offences. The unique structure and procedure of each of these Mental Health Courts are investigated with due consideration to the eligibility criteria of each and the sanctions employed for non-compliance of the court-monitored treatment programmes. Further, the successes and challenges of each model are highlighted. Finally, a proposal is made for a Mental Health Court model mindful of the uniquely South African factors that have to be taken into account when building such a model. Amendments to the existing legislative framework are proposed to incorporate a Mental Health Court as a therapeutic response to mentally ill accused persons in the South African criminal justice system. / Criminal and Procedural Law

Modelling of Private Infrastructure Debt in a Risk  Factor Model / Modellering av Privat Infrastrukturskuld i enRiskfaktormodell

Bartold, Martina January 2017 (has links)
Allocation to private infrastructure debt investments has increased in the recent years [15]. For managers of multi-asset portfolios, it is important to be able to assess the risk of the total portfolio and the contribution to risk of the various holdings in the portfolio. This includes being able to explain the risk of having private infrastructure debt investments in the portfolio. The modelling of private infrastructure debt face many challenges, such as the lack of private data and public indices for private infrastructure debt. In this thesis, two approaches for modelling private infrastructure debt in a parametric risk factor model are proposed. Both approaches aim to incorporate revenue risk, which is the risk occurring from the type of revenue model in the infrastructure project or company. Revenue risk is categorised into three revenue models; merchant, contracted and regulated, as spread level differences can be distinguished for private infrastructure debt investments using this categorisation. The difference in spread levels between the categories are used to estimate β coefficients for the two modelling approaches. The spread levels are obtained from a data set and from a previous study. In the first modelling approach, the systematic risk factor approach, three systematic risk factors are introduced where each factor represent infrastructure debt investments with a certain revenue model. The risk or the volatility for each of these factors is the volatility of a general infrastructure debt index adjusted with one of the β coefficients. In the second modelling approach, the idiosyncratic risk term approach, three constant risk terms for the revenue models are added in order to capture the revenue risk for private infrastructure debt investments. These constant risk terms are estimated with the β coefficients and the historical volatility of a infrastructure debt index. For each modelling approach, the commonly used risk measures standalone risk and risk contribution are presented for the entire block of the infrastructure debt specific factors and for each of the individual factors within this block. Both modelling approaches should enable for better explanation of risk in private infrastructure debt investments by introducing revenue risk. However, the modelling approaches have not been backtested and therefore no conclusion can be made in regards to whether one of the proposed modelling approaches actually is better than current modelling approaches for private infrastructure debt. / Investeringar i privat infrastrukturskuld har ökat de senaste åren [15]. För βägare av portföljer med investeringar i samtliga tillgångsslag är det viktigt att kunna urskilja risken från de olika innehaven i portföljen. Det finns många utmaningar vad gäller modellering av privat infrastrukturskuld, så som den begränsade mängden privat data och publika index för privat infrastrukturskuld. I denna uppsats föreslås två tillvägagångssätt för att modellera privat infrastrukturskuld i en parametrisk riskfaktormodell. Båda tillvägagångssätten eftersträvar att inkorporera intäktsrisk, vilket är risken som beror på den underliggande intäktsmodellen i ett infrastrukturprojekt eller företag. Intäksrisk delas in i intäksmodellerna "merchant", "contracted" och "regulated", då en skillnad i spreadnivå mellan privata infrastrukturskuldinvesteringar kan urskiljas med denna kategorisering. Skillnaden i spreadnivå mellan de olika kategorierna används för att estimera β -koefficienter som används i båda tillvägagångssätten. Spreadnivåerna erhålls från ett dataset och från en tidigare studie. I det första tillvägagångssättet, den systematiska riskfaktor-ansatsen, introduceras tre systematiska riskfaktorer som representerar infrastrukturskuldinvesteringar med en viss intäktsmodell. Risken eller volatiliten för dessa faktorer är densamma som volatiliteten för ett index för infrastrukturskuld justerat med en av β -koefficienterna. I det andra tillvägagångssättet, den idriosynktratiska riskterm-ansatsen, adderas tre konstanta risktermer för intäktsmodellerna för att fånga upp intäktsrisken i de privata infrastrukturinvesteringarna. De konstanta risktermerna är estimerade med β -koefficienterna och en historisk volatilitet för ett index för infrastrukturskuld. För båda tillvägagångssätten presenteras riskmåtten stand-alone risk1 och risk contribution2. Riskmåtten ges för ett block av samtliga faktorer för infrastrukturskuld och för varje enskild faktor inom detta block. Båda tillvägagångssätten borde möjliggöra bättre förklaring av risken för privata infrastrukturskuldinvesteringar i en större portfölj genom att ta hänsyn till intäktsrisken. De två tillvägagångssätten för modelleringen har dock ej testats. Därför kan ingen slutsats dras med hänsyn till huruvida ett av tillvägagångssätten är bättre än de som används för närvärande för modellering av privat infrastrukturskuld.

Stereotyper med lyckliga slut : En narrativ-analytisk undersökning om hur autism representeras i två samtida populära filmer / Stereotypes with happy endings : A narrative-analytical study of how autism is represented in two contemporary popular films

Lindblom, Frida January 2021 (has links)
This study looks at how autism is represented by characters in popular film, by analyzing the protagonists of two films, I rymden finns inga känslor and Please Stand By, with narrative and character analysis and then interpreting the result against social constructionism and theories of normality. The analysis results in the emergence of stereotypical characters in both films, and a statement that this can help to form a kind of symbol for what autism means for non-autistic individuals. The discussion states that in order to combat stereotypical representation in popular media, a change is needed from a medical model to a social model together with a change in the discourse around what autism means for autistic individuals.

Daily stand up meetings - hiss eller diss? / Daily stand up meetings - hit or shit?

Stedt, Lotten, Vutolen, Cajsa January 2022 (has links)
Syftet med studien är att beskriva hur agila team upplever digitala DSM samt kartlägga vilka tekniska ochsociala behov som uppfylls och/eller saknas. De teman som undersöktes var hur digitala DSMgenomfördes praktiskt, vilka tekniska verktyg som användes samt vilken social inverkan det hade påteamet. För att ge riktning åt studien skrevs tre forskningsfrågor med tillhörande tre hypoteser sombaseras på tidigare forskning. Hypoteserna som utformades löd; (H1) vid digitala DSM behöver fler än detre centrala frågorna diskuteras, (H2) funktioner som simulerar den fysiska arbetsplatsen är bärande för ettfungerande digitalt DSM och (H3) minskad informell kommunikation vid distansarbete kompenseras avatt digitala DSM utökas i tid. Studien har genomförts genom att samla in data från en webbaserad enkätsom skickades ut med hjälp av grindvaktare till flera agila team. Enkäten bestod av både kvalitativafritextfrågor och kvantitativa flervalsfrågor som baserades på Theory of distances (Bjarnason et al., 2016),en sammanställning av intergroup theory samt tidigare forskning. Resultatet visade att små skillnaderfanns mellan traditionella och digitala DSM. Hybrid-varianter, minskad informell kommunikation ochbrist på heltäckande funktioner ansågs vara den största utmaningen med digitala DSM. Fördelarnaupplevdes olika beroende på personliga förutsättningar hos respondenterna. Slutsatserna som kunde drasav studien var att det saknades funktioner för att stödja synlighet av emotioner och kroppsspråk men attfunktioner, som skärmdelning, gav en gemensam bild av projektet. Den informella kommunikationenbehöver aktivt inkluderas vid digitala DSM vilket gör att digitala DSM blir längre än traditionella. Vidareforskning hade kunnat fokusera på virtuella mötesrum som en del av lösningen på identifierade problem. / The purpose of the study is to describe how agile teams experience digital DSM and to elucidate whichtechnical and social needs that are met and/or missing. Following themes were examined: how digitalDSM was implemented in practice, what technical tools were used and what social impact digital DSMshad on the team. To give direction to the study, three research questions were formulated with threeassociated hypotheses based on previous research. The hypotheses that were formed were; (H1) in digitalDSM, more than the three central questions were discussed, (H2) functions that simulate the physicalworkplace are essential for a functioning digital DSM and (H3) reduced informal communication inremote work is compensated by time extended digital DSM. The study was conducted by collecting datafrom a web-based survey that was provided to several agile teams with the help of gatekeepers. Thequestionnaire consisted of both qualitative open questions and quantitative multiple-choice questionsbased on Theory of distances (Bjarnason et al., 2016), a compilation of intergroup theory and previousresearch. The results show that there are small differences between traditional and digital DSMs. Hybridvariants, reduced informal communication and lack of comprehensive features were considered to be thegreatest challenge with digital DSM. The benefits were experienced differently depending on the personalcharacteristics of the respondents. The conclusions of the study were that there were no technicalfunctions to back the visibility of emotions and body language, but that functions such as screen sharing,gave a common picture of the project. The informal communication needs to be actively included indigital DSMs which makes digital DSMs more protracted than traditional ones. Further research can focus on virtual meeting rooms as part of the solution to the identified problems

Central and Peripheral Weight Gain Affect Trunk Kinematics and Lower-Extremity Muscle Activation Differently During Sit-To-Stand

Walaszek, Michelle Christine 01 January 2016 (has links)
Background: Obesity-induced alterations in biomechanics and muscle recruitment during activities of daily living, such as sit-to-stand (STS) are often attributed to increases in adipose tissue (AT) mass. Central or peripheral distribution of AT may differently affect biomechanics and muscle recruitment. Methods: Fifteen healthy, normal weight (BMI 22.4 ± 1.9 kg/m2, 24.1 ± 4.2 years) subjects volunteered. External loads equivalent to a 5 kg/m2 BMI increase were applied in three conditions: unloaded (UN), centrally loaded (CL), and peripherally loaded (PL). Subjects completed three successful STS movements in a backless chair under each load condition in random order. Motion analysis and lower extremity surface electromyography (EMG) were measured. Results: Compared to UN and CL, PL significantly increased support width during STS. PL also significantly increased maximum trunk flexion compared to CL. Peak and total VM EMG activity were significantly increased during CL, compared to UN and PL. During CL, peak VL EMG activity was significantly greater than UN. Conclusions: Central and peripheral weight gain induce different biomechanical adaptations during STS. Central weight gain increases knee extensor muscle activity during STS independent of biomechanical changes. In contrast, peripheral weight gain increases support width and trunk flexion with minimal EMG changes during STS.

A probabilistic method of modelling energy storage in electricity systems with intermittent renewable energy

Barton, John P. January 2007 (has links)
A novel probabilistic method has been developed for modelling the operation of energy storage in electricity systems with significant amounts of wind and solar powered generation. This method is based on a spectral analysis of the variations of wind speed and solar irradiance together with profiles of electrical demand. The method has been embodied in two Matlab computer programs: Wind power only: This program models wind power on any time scale from seconds to years, with limited modelling of demand profiles. This program is only capable of modelling stand-alone systems, or systems in which the electrical demand is replaced by a weak grid connection with limited export capacity. 24-hours: This program models wind power, solar PV power and electrical demand, including seasonal and diurnal effects of each. However, this program only models store cycle times (variations within a time scale) of 24 hours. This program is capable of modelling local electrical demand at the same time as a grid connection with import or export capacity and a backup generator. Each of these programs has been validated by comparing its results with those from a time step program, making four Matlab programs in total. All four programs calculate the power flows to and from the store, satisfied demand, unsatisfied demand and curtailed power. The programs also predict the fractions of time that the store spends full, empty, filling or emptying. The results obtained are promising. Probabilistic program results agree well with time step results over a wide range of input data and time scales. The probabilistic method needs further refinement, but can be used to perform initial modelling and feasibility studies for renewable energy systems. The probabilistic method has the advantage that the required input data is less, and the computer run time is reduced, compared to the time step method.

Phosphorus management practices for soybean production in Manitoba

Bardella, Gustavo 12 September 2016 (has links)
The increase in soybean production in Manitoba has raised many questions about phosphorus management for achieving high yields of modern varieties. Soybean’s tolerance to seed-placed fertilizer and response to added fertilizer P were evaluated in a 28 site-year study, and the yield response to soil test P concentrations was evaluated in seven site-years, in a second study. Plant stand reduction caused by fertilizer toxicity when applied with the seed was rare, but was most likely in soils with medium to coarse texture or when seeding equipment lightly disturbed the soil, or provided little seed bed utilization. Severe plant stand reduction decreased seed yield in two site-years. Seed yield increase to P fertilization was rarely observed, regardless of fertilizer P rate, P placement or soil test P. In only one site-year there was a significant effect of fertilizer rate, where 45 and 90 kg P2O5 ha-1 increased yield by approximately 15%, compared to the control. Regardless of soil test P, seed yield response to soil P fertility was never observed. / October 2016

Fem and Funny: Three Women Who Changed the Face of Stand-Up Comedy

Blackburn, Rachel Eliza 10 April 2013 (has links)
Phyllis Diller, Joan Rivers, and Lisa Lampanelli as performers demonstrate an arc of evolving female empowerment in the world of stand-up comedy. In this thesis I shall study the development of each woman’s career by examining her material, progression of her comic persona, and relationship to women’s gender roles, both personally and professionally. While there are many other female comics who contribute to the story of women’s stand-up comedy in the contemporary period (in particular, Moms Mabley and Elayne Boosler), Diller, Rivers and Lampanelli each represent a distinct shift in how their persona combined with subject matter, allowing women to break new barriers in terms of comic performance. Diller’s comedy carved a space for Rivers’, and Rivers’ comedy carved a space for the likes of Lampanelli. In viewing the trajectory of their effect on comedy as a whole, we can see how each woman asserted herself in stand-up performance, and forever changed the nature of who was allowed to get up on stage, and also, what they were allowed to say by their audiences. To quote Joan Rivers, “First there was a gasp…and then there was a laugh” (Rivers “Piece of Work”).
