Kanalrhodopsine (ChRs) sind lichtgesteuerte Ionenkanäle, welche nach Absorption eines Photons durch den Retinal-Cofaktor einen passiven Ionentransport über die Zellmembran katalysieren. Im Zuge von optogenetischen Anwendungen wird diese Reaktion für die Beeinflussung der Ionenhomöostase von verschiedenen Zelltypen und Geweben ausgenutzt. Zu Beginn dieser Arbeit wurden lichtinduzierte Strukturänderungen und Protontransferschritte in einem breiten Zeitbereich (Nanosekunden bis Minuten) in dem grün-absorbierenden ChR ReaChR mithilfe von stationärer und transienter UV-vis- und Fourier-Transform-Infrarot-Spektroskopie (FTIR) untersucht. Auf Basis der experimentellen Daten wurde ein komplexes Photozyklus-Modell konzipiert. Anschließend wurde die IR-aktive, nichtkanonische Aminosäure p-Azido-L-phenylalanin (azF) mittels Stopp-Codon-Suppression ortsspezifisch an mehreren Positionen innerhalb der vermuteten ionenleitenden Kanalpore in ReaChR inkorporiert und mit FTIR untersucht. azF ist sensitiv gegenüber Polaritätsänderungen und absorbiert in einem hochfrequenten Bereich (~2100 cm-1). Aufgrund der großen spektralen Separation zu endogenen Proteinschwingungen (< 1800 cm-1) können globale Konformations- und lokale Hydratisierungsänderungen simultan detektiert werden. Die erhobenen Daten leisten einen wichtigen Beitrag zum Verständnis der Bildung einer temporären Wasserpore in ChRs und demonstrieren zum ersten Mal den erfolgreichen in-vivo-Einbau einer artifiziellen Aminosäure in mikrobielle Rhodopsine und dessen schwingungsspektroskopische Analyse. Die Methode bietet aufgrund ihrer hohen Ortsauflösung ein großes Potential für die Studie von Mikroumgebungen innerhalb komplexer Proteinensemble. / Channelrhodopsins (ChRs) are light-gated ion channels. Upon absorption of a photon, the retinal chromophore isomerizes and drives conformational changes within the protein, which lead to a passive ion transport across the cell membrane. This capability is used for optogenetic applications to manipulate ionic homeostasis of different cell types and entire organisms. Within the work, light-induced structural changes and proton transfer steps were studied in the green-absorbing ChR ReaChR in great detail by steady-state and transient UV-vis and Fourier transform infrared spectroscopy (FTIR). The data were merged into a complex photocycle model. Next, the IR-active, unnatural amino acid p-azido-L-phenylalanine (azF) was site-specifically introduced at several sites of the putative ion pore of ReaChR by stop codon suppression. azF is sensitive to polarity changes and absorbs in a clear spectral window lacking endogenous protein vibrations. Thus, FTIR measurements of labeled mutants report for global conformational changes (< 1800 cm-1) and local hydration changes (~2100 cm-1) simultaneously. The presented findings reveal crucial insights regarding formation of a transient water pore in ChRs and demonstrate the first report of the successful in-vivo incorporation of an artificial amino acid into a microbial rhodopsin and its subsequent spectroscopic investigation. Additionally, the so far unprecedented spatial resolution renders this methodology superior over conventional FTIR methods to study microenvironments within complex protein ensembles.

Cette thèse traite de l’acquisition des occlusives sourdes /p t k/ et sonores /b d g/ du français par 11 locutrices taïwanaises de niveau intermédiaire à avancé. La situation de Taïwan est qualifiée de diglossique, les locuteurs parlent généralement deux langues dont les principales sont le chinois mandarin et le taïwanais. Le chinois mandarin possède les occlusives /p t k ph th kh/ tandis que le taïwanais possède les occlusives /b g p t k ph th kh/. L’analyse acoustique des logatomes CVCVCVC où C=/b d g p t k/ et V=/a i u/ révèle une grande hétérogénéité entre les locutrices : les indices des natifs du français pour opposer entre sourdes et sonores sont parfois utilisés par les non-natifs, parfois non. On note l’influence du chinois mandarin. Un test de perception révèle une moins bonne discrimination des paires de consonnes /b p/, /d t/ et /g k/ en syllabe CV si V=/a/, comparé à /i u/. Ces résultats suggèrent une tendance générale chez ces auditrices à mieux discriminer les occlusives du français lorsque le VOT des sourdes est plus long et à ne pas tenir compte du VOT négatif des voisées. En perception, les indices pour discriminer les occlusives aspirées et non-aspirées du chinois mandarin semblent ainsi également être utilisés en français. Nous n’avons pas relevé de signe d’une influence du taïwanais, où l’opposition de voisement existe cependant. / This dissertation deals with the acquisition of French voiceless stops /p t k/ and voiced stops /b d g/ by 11 Taiwanese intermediate or advanced learners of L2 French. The linguistic situation in Taiwan is described as diglossia. Most speakers speak two languages, mainly Mandarin Chinese and Taiwanese. Mandarin Chinese has plosives /p t k ph th kh/ while Taiwanese has /b g p t k ph th kh/. An acoustic analysis of CVCVCVC logatoms where C = /b d g p t k/ and V = /a i u/ shows important heterogeneity among speakers. The cues used by French native speakers to oppose voiceless and voiced stops are irregularly used by non-native speakers. The influence of Mandarin Chinese is noted. A perception test shows poorer discrimination among pairs of consonants (/b p/, /d t/ and /g k/) in CV syllable when V = /a/, as compared to /i u/. The results show that non-native listeners tend to, firstly, better discriminate the voiceless plosives of French when the VOT is longer and secondly, ignore the negative VOT of voiced stops. As regards perception, the cues used in Mandarin Chinese to discriminate between aspirated and non-aspirated stops consonants seem to be used in French too. No clue to the influence of Taiwanese has been found, although the opposition of voicing exists.

The connected vehicle technology presents an innovative way of sharing information between vehicles and the transportation infrastructure through wireless communications. The technology can potentially solve safety, mobility, and environmental challenges that face the transportation sector. Signal phasing and timing information is one category of information that can be broadcasted through connected vehicle technology. This thesis presents an in-depth study of possible ways signal phasing and timing information can be beneficial as far as safety and mobility are concerned. In total, three studies describing this research are outlined. The first study presented herein focuses on data collection and calibration efforts of the simulation model that was used for the next two studies. The study demonstrated a genetic algorithm procedure for calibrating VISSIM discharge headways based on queue discharge headways measured in the field. Video data was used to first compute intersection discharge headways for individual vehicle queue position and then to develop statistical distributions of discharge headways for each vehicle position. Except for the 4th vehicle position, which was best fitted by the generalized extreme value (GEV) distribution, the Log-logistic distribution was observed to be the best fit distribution for the rest of vehicle positions. Starting with the default values, the VISSIM parameters responsible for determining discharge headways were heuristically adjusted to produce optimal values. The optimal solutions were achieved by minimizing the Root Mean Square Error (RMSE) between the simulated and observed data. Through calibration, for each vehicle position, it was possible to obtain the simulated headways that reflect the means of the observed field headways. However, calibration was unable to replicate the dispersion of the headways observed in the field mainly due to VISSIM limitations. Based on the findings of this study, future work on calibration in VISSIM that would account for the dispersion of mixed traffic flow characteristics is warranted. The second study addresses the potential of connected vehicles in improving safety at the vicinity of signalized intersections. Although traffic signals are installed to reduce the overall number of collisions at intersections, rear-end collisions are increased due to signalization. One dominant factor associated with rear-end crashes is the indecisiveness of the driver, especially in the dilemma zone. An advisory system to help the driver make the stop-or-pass decision would greatly improve intersection safety. This study proposed and evaluated an Advanced Stop Assist System (ASAS) at signalized intersections by using Infrastructure-to-Vehicle (I2V) and Vehicle-to-Vehicle (V2V) communication. The proposed system utilizes communication data, received from Roadside Unit (RSU), to provide drivers in approaching vehicles with vehicle-specific advisory speed messages to prevent vehicle hard-braking upon a yellow and red signal indication. A simulation test bed was modeled using VISSIM to evaluate the effectiveness of the proposed system. The results demonstrate that at full market penetration (100% saturation of vehicles equipped with on-board communication equipment), the proposed system reduces the number of hard-braking vehicles by nearly 50%. Sensitivity analyses of market penetration rates also show a degradation in safety conditions at penetration rates lower than 40%. The results suggest that at least 60% penetration rate is required for the proposed system to minimize rear-end collisions and improve safety at the signalized intersections. The last study addresses the fact that achieving smooth urban traffic flow requires reduction of excessive stop-and-go driving on urban arterials. Smooth traffic flow comes with several benefits including reduction of fuel consumption and emissions. Recently, more research efforts have been directed towards reduction of vehicle emissions. One such effort is the use of Green Light Optimal Speed Advisory (GLOSA) systems which use wireless communications to provide individual drivers with information on the approaching traffic signal phase and advisory speeds to arrive at the intersection on a green phase. Previously developed GLOSA algorithms do not address the impact of time to discharge queues formed at the intersection. Thus, this study investigated the influence of formed intersection queues on the performance of GLOSA systems. A simulation test-bed was modeled inside VISSIM to evaluate the algorithm’s effectiveness. Three simulation scenarios were designed; the baseline with no GLOSA in place, scenario 2 with GLOSA activated and queue discharge time not considered, and scenario 3 with GLOSA activated and where queue dissipation time was used to compute advisory speeds. At confidence level the results show a significant reduction in the time spent in queue when GLOSA is activated (scenarios 2 and 3). The change in the average number of stops along the corridor was found not to be significant when the base scenario was compared against scenario 2. However, a comparison between scenarios 2 and 3 demonstrates a significant reduction in the average number of stops along the corridor, and also in the time spent waiting in queues

Deux exemples de tunnels optiques sont étudiés par des méthodes de l'optique femtoseconde pour leurs propriétés propagatives. Le premier est une opale artificielle : un matériau de la famille des cristaux photoniques aux propriétés analogues dans le domaine optique à celles des semiconducteurs. Ils possèdent une bande interdite photonique (BIP) empêchant pour toutes les directions la propagation de photons dont l'énergie se trouve dans cette bande. Le second système est un bi-prisme en réflexion totale.<br> La première partie est consacrée aux opales : empilements réguliers de sphères de silice submicrométriques. Chaque phase de l'élaboration est en revue. Une description théorique des propriétés des cristaux photoniques est faite pour plusieurs structures. On en déduit que les opales n'ont pas de BIP mais une "stop-band" inhibant la transmission des photons dont la bande d'énergies dépend de la direction. Les caractéristiques structurelles, mises en relation avec les propriétés spectrales, sont abordées par des méthodes microscopiques et optiques. Un dispositif de temps de vol a été réalisé pour déterminer les propriétés propagatives d'opales sondées par un continuum en utilisant un fenêtrage temporel par absorption à deux photons dans du ZnS. Après des corrections en fréquence et en temps, on dispose du profil spectral de vitesse de groupe. Celui-ci est expliqué par un modèle basé sur la relation de Kramers-Krönig. Cela permet de décrire la "stop-band" comme un système à "deux niveaux photoniques".<br> La dernière partie est dédiée à l'étude de la transposition en optique d'un nouvel effet prédit dans les conditions de l'effet tunnel : "l'évaporation quantique". Il se manifeste par l'augmentation drastique de la transmission d'un paquet d'onde. Il se produit en transférant à l'instant de la réflexion une petite quantité de mouvement au paquet d'onde. Un bi-prisme en réflexion totale séparé par une lame d'air est employé pour reproduire les conditions de cet effet. On utilise une technique pompe-sonde qui simule le transfert de moment par effet Kerr. Après analyse des effets en compétition avec l'évaporation quantique, nous observons des signaux qui, une fois traités selon des critères précis, ont les caractéristiques de l'effet recherché. Ceci constitue une présomption de la première observation en optique de ce nouvel effet.

The implementation of the stop-and-frisk duty of the police is extremely closely related to the intervention of people¡¦s freedom of action, privacy and moral integrity right. In the past, the basis of law for the fulfillment of the stop-and-frisk duty by the police authorities was only the ¡§Regulations of the Police Duties.¡¨ Nevertheless, the Regulations contained no content of the objective for initiating the stop-and-frisk duty, the stop-and-frisk procedures and the means of relief. The Regulations only mention the term of stop and frisk, but lack the soul and body of stop and frisk. Based on the term of stop and frisk, the police always legitimized the enforcement of many banning acts, such as searching the house of a citizen in the midnight in the name of fulfilling the stop-and-frisk duty of the household. Similar behaviors were frequently found, thus creating many complaints from the citizens. After the chancellor of Judicial Yuan made an explanation of Shih No. 535, a lot of feedbacks from the police were undoubtedly created. To Taiwan, this is a great leap in marching towards a country under the rule of law. It has made the police authorities understand the importance of administrative procedures, and urged the birth of ¡§Act of Exercise of the Police Powers.¡¨ In the new Act, the behavior of stop and frisk is replaced by the term ¡§checking of identity.¡¨ A local scholar, Wu Keng once mentioned that ¡§stop and frisk¡¨ had been abolished and not been used. However, is it the fact? This paper is going to investigate the issue. Besides, does the constitution of the Act mean that the stop-and-frisk legal system is sound enough? This is another issue worthy of studying. Due to the vastness and un-limitedness of Administration Act, there is no country in the world having a sound and complete Administration Act. Nevertheless, viewing at the theories and principles of Administration Act, it can be generally divided into five main structures: basic principles, administrative organization, limit of administrative rights, administrative relief and administrative surveillance. If an administrative legal system is fearless to receive the examination based on each item of the five main structures of Administrative Law, it can be called a sound and complete administrative legal system. Another local scholar, Li Chen-Shan thinks that the separation of criminal law from Administration Act has led to the division of the police¡¦s mission of maintaining public security into two parts: ¡§prevention of harm¡¨ and ¡§criminal arrest,¡¨ which prevents the administrative harm and the criminal harm respectively. While they cross over the administrative area and the criminal area, stop-and-frisk duty belongs to an administrative behavior. Since it just belongs to the ¡§prevention of harm,¡¨ it should be regulated by the theories and principles of Administration Act. Therefore, this paper takes the stop-and-frisk legal system of police officers as the main body of the study. From the viewpoint of the science of law, this paper employs the abovementioned basic theories of Administration Act, i.e. the ¡§five major structures¡¨ of administrative principles, administrative organization, limit of administrative rights, administrative relief and administrative surveillance, as the research approaches of the study to examine the stop-and-frisk system of the police officers of Taiwan. Under this mode of thinking, the study is divided into seven chapters. Chapter 1 is Introduction, which firstly raises queries over the practice of fulfilling stop-and-frisk duty by the police authorities, and then introduces the motives, objectives, research approaches, research area and research structure of the paper. Chapter 2 is Basic Principles of Stop-and-Frisk Legal System, which firstly reviews the basic concepts of the two terms, the police and stop and frisk, and then investigates the background for the constitution of stop-and-frisk legal system. In this chapter, substantial information from the social aspect of the practical phenomena, the economic aspect of the optimal adjustment, the political aspect of negotiation and compromising, and the legal aspect of acts and regulations, is presented, enabling us to have a deeper understanding of the practical phenomena of stop-and-frisk legal system. After that, the chapter analyzes and compares the international aspects of the stop-and-frisk legal system of three countries, Germany, Japan and the United States, so as to take them as the references for the improvement of local legal system. Then, the chapter investigates the concepts of the rule of law of stop-and-frisk legal system, as well as the nature of stop and frisk from the angles of the three administrative principles according to laws and the seven principles of procedural justice. Finally, the chapter explores the relationship between stop-and-frisk legal system and the participation of the parties concerned. It is hoped that through the participation methods of the parties concerned, the stop-and-frisk legal system can become more sound and complete. Chapter 3 introduces the administrative organization of stop-and-frisk legal system by starting from the organizational structure of the existing police organization, and then investigates the organizational structure of the police authorities, staff on duty (including the assistants on duty), the budget and other problems. It is expected that a complete organizational structure can be formed to achieve a smooth operation of the stop-and-frisk practices of police officers. Chapter 4 discusses about the design and use of the limit of the rights of stop-and-frisk legal system. The chapter investigates each item stipulated in Administrative Procedure Act,¡¨ including the administrative plan, administrative legislation, legislative punishment, administrative investigation, administrative agreement, administrative guidance and the fulfillment of administrative obligations, hoping to make a comprehensive investigation of the limit of the stop-and-frisk rights. Chapter 5 introduces the relief and problem-solving measures of stop-and-frisk legal system. There is an ancient saying about law, ¡§Where there is right, there is relief.¡¨ This chapter firstly mentions the right of dissent, and then discusses about the issues of pleading, administrative lawsuit, national compensation, compensation of loss and referendum, intending to cover every detail of the rights of citizens. Chapter 6 talks about the administrative surveillance of stop-and-frisk legal system, and investigates the internal surveillance mechanism of the police authorities themselves and the external fair surveillance mechanism of the third parties. It is hoped that the surveillance mechanisms can meet the national and public requirements, no matter from the legal facet or the practical facet. Chapter 7 is the Conclusions and Suggestions, which synthesize the researcher¡¦s discussion of the five main structures of Administration Act. Over some specific items of the existing stop-and-frisk legal system of the police officers that need to be revised or deleted, the chapter proposes concrete suggestions, which can be a reference for the police authorities in exercising their powers, and working on the goals of building the administrative standards of Taiwan according to law, and improving the legal image of Taiwan under the rule of law.

Graves discusses the important role that women played in the anti-ERA campaign in Georgia during the late 1970s and early 1980s. The Equal Rights Amendment (ERA) was a controversial and divisive piece of legislation that polarized both legislators and constituents throughout the United States. Graves uses the anti-ERA campaign in Georgia as a model for studying the women who opposed the ERA on a national level. She writes about the differences between the feminist movement and the conservative grassroots movement, the role that anti-ERA women played in the rise of the New Right, and the legacy of the ERA’s failure in contemporary political context. Graves uses interviews and primary resource documents of the women involved in the campaign as well as a plethora of scholarly materials previously written about the ERA.

<p> <p>&nbsp / </p> </p> <p align="left">Whilst policy formulation has been extensively studied and theorised in the literature, far less attention has been paid until fairly recently to the issue of policy implementation. For a long time it was more or less assumed that once policy was formulated, implementation was a relatively straightforward administrative matter. In the past twenty or thirty years, however, public administration scholars (such as Pressman and Wildavsky and, in the South African context, Brynard and de Coning) have devoted more attention to unravelling the complexities of policy implementation. The current study intends to apply these more theoretical approaches to an analysis of the implementation of the 1997 White Paper for Social Welfare with particular respect to children in conflict with the law, focusing specifically on the One Stop Child Justice Centre in Mangaung, Bloemfontein. Welfare Service in South Africa before 1994 had a racial bias with services mostly unavailable to the majority of the citizens of the country. The 1997 White Paper for Social Welfare, based on a developmental approach to social welfare, was designed to take the country in a new and inclusive direction. In line with South Africa&rsquo / s 1996 ratification of the UN Convention on the Rights of the Child, as well as other international instruments, Section 4 of Chapter 8 of the White Paper focuses on crime prevention through development and restorative justice, and recommends diversion wherever possible in the case of juveniles. With respect to Juvenile justice, this section of the White Paper makes provision for the establishment of One Stop Child Justice Centres, where a variety of services, from Social Development, the Department of Justice, the South African Police Services, Correctional Services, and the NPA, would be available to clients under one roof. All of these role players, it was envisaged, would operate as a multi-disciplinary team to achieve the objectives of the White Paper with respect to developmental and restorative forms of justice. The Centre at Mangaung is one of only a few centres to have been established as yet in South Africa. Although focusing in particular on the implementation of the 1997 White Paper, the study is also informed by other policy and legislative measures with respect to juvenile justice, in particular the Child Justice Bill of 2002 (now the Child Justice Act of 2008) and the Probation Services Amendment Act of 2002. It is generally accepted by the Government and its critics alike that the policy scene in South Africa in the period since 1994 has been characterized by good policies but poor execution. This is, however, a relatively untested hypothesis and needs further investigation. In the light of this, it is anticipated, that the present study will make a contribution to the literature on policy implementation in South Africa, as well as providing useful insights and lessons that can inform general government policy in this regard, and policy with respect to juvenile justice in particular. Within the general context of the 1997 White Paper for Social Welfare and the Department of Social Development&rsquo / s Integrated Service Delivery Model, and the specific context of the Mangaung One Stop Child Justice Centre, the overall purpose of the study is to scrutinize the apparent discontinuity between policy design on the one hand and policy implementation on the other. More specifically, though, the objectives of the study are: (i) to examine the content of the 1997 White Paper for Social Welfare in general and more specifically the section on children in conflict with the law, (ii) to provide a historical overview of the delivery of services to youth in conflict with the law prior to the first democratic elections (1994) in South Africa, (iii) to examine what the concept of &lsquo / integrated service delivery&rsquo / means to the different role-players at the One Stop Child Justice Centre, (iv) to examine the existing resources (human, financial and other) for successful implementation of the policy,(v) to examine whether there are procedures in place to encourage co-operation among stakeholders at the One Stop Child Justice Centre, (vi) to examine the successes, challenges and opportunities presented by the implementation of this policy at the One Stop Child Justice Centre and, (vii) to identify gaps between policy and implementation and make recommendations towards more successful implementation. Detailed semi-structured interviews were conducted with the Centre Manager and senior representatives of all the services involved (Social Development, the SAPS, Magistrates, the Probation Service, and Prosecutors). The interview questions focus mainly on implementation issues and challenges, but also gather information on the knowledge of the interviewees on the content of the policy. In addition, in order to validate and compare the data collected from these respondents, semi-structured interviews were held with six parents/guardians of children in conflict with the law who had been serviced by the centre. Official documents of the centre, such as annual reports, were also consulted for purposes of triangulation. Detailed transcripts will be made of all the interviews. In analysing the data, use was made in particular of the 5C Protocol advocated by Brynard and De Coning (2006) in their study of policy implementation in South Africa. The five C&rsquo / s include the Content of the policy, the Context in which the policy is implemented, Commitment from those implementing the policy, the role of Clients and Coalitions, and the Capacity of those tasked with implementing the policy. In addition other C&rsquo / s which have an impact on policy implementation (such as communication, co-ordination, and change management) will also be considered. Confidentiality of data gathered and anonymity of respondents were ensured by not requiring any personal details from the survey instruments. The sole purpose of using the data gathered for research was communicated to the respondents on the front page of the survey instruments. The choice of also not answering questions raised was respected.</p>

In addition, in order to validate and compare the data collected from these respondents, semi-structured interviews were held with six parents/guardians of children in conflict with the law who had been serviced by the centre. Official documents of the centre, such as annual reports, were also consulted for purposes of triangulation. Detailed transcripts will be made of all the interviews. In analysing the data, use was made in particular of the 5C Protocol advocated by Brynard and De Coning (2006) in their study of policy implementation in South Africa. The five C&rsquo / s include the Content of the policy, the Context in which the policy is implemented, Commitment from those implementing the policy, the role of Clients and Coalitions, and the Capacity of those tasked with implementing the policy. In addition other C&rsquo / s which have an impact on policy implementation (such as communication, co-ordination, and change management) will also be considered. Confidentiality of data gathered and anonymity of respondents were ensured by not requiring any personal details from the survey instruments. The sole purpose of using the data gathered for research was communicated to the respondents on the front page of the survey instruments. The choice of also not answering questions raised was respected.</p>

<p>&nbsp / </p> <p>&nbsp / </p> <p>&nbsp / </p> <p align="left">Whilst policy formulation has been extensively studied and theorised in the literature, far less attention has been paid until fairly recently to the issue of policy implementation. For a long time it was more or less assumed that once policy was formulated, implementation was a relatively straightforward administrative matter. In the past twenty or thirty years, however, public administration scholars (such as Pressman and Wildavsky and, in the South African context, Brynard and de Coning) have devoted more attention to unravelling the complexities of policy implementation. The current study intends to apply these more theoretical approaches to an analysis of the implementation of the 1997 White Paper for Social Welfare with particular respect to children in conflict with the law, focusing specifically on the One Stop Child Justice Centre in Mangaung, Bloemfontein. Welfare Service in South Africa before 1994 had a racial bias with services mostly unavailable to the majority of the citizens of the country. The 1997 White Paper for Social Welfare, based on a developmental approach to social welfare, was designed to take the country in a new and inclusive direction. In line with South Africa&rsquo / s 1996 ratification of the UN Convention on the Rights of the Child, as well as other international instruments, Section 4 of Chapter 8 of the White Paper focuses on crime prevention through development and restorative justice, and recommends diversion wherever possible in the case of juveniles. With respect to Juvenile justice, this section of the White Paper makes provision for the establishment of One Stop Child Justice Centres, where a variety of services, from Social Development, the Department of Justice, the South African Police Services, Correctional Services, and the NPA, would be available to clients under one roof. All of these role players, it was envisaged, would operate as a multi-disciplinary team to achieve the objectives of the White Paper with respect to developmental and restorative forms of justice. The Centre at Mangaung is one of only a few centres to have been established as yet in South Africa. Although focusing in particular on the implementation of the 1997 White Paper, the study is also informed by other policy and legislative measures with respect to juvenile justice, in particular the Child Justice Bill of 2002 (now the Child Justice Act of 2008) and the Probation Services Amendment Act of 2002. It is generally accepted by the Government and its critics alike that the policy scene in South Africa in the period since 1994 has been characterized by good policies but poor execution. This is, however, a relatively untested hypothesis and needs further investigation. In the light of this, it is anticipated, that the present study will make a contribution to the literature on policy implementation in South Africa, as well as providing useful insights and&nbsp / sessons that can inform general government policy in this regard, and policy with respect to juvenile justice in particular. Within the general context of the 1997 White Paper for Social Welfare and the Department of Social Development&rsquo / s Integrated Service Delivery Model, and the specific context of the Mangaung One Stop Child Justice Centre, the overall purpose of the study is to scrutinize the apparent discontinuity between policy design on the one hand and policy implementation on the other. More specifically, though, the objectives of the study are: (i) to examine the content of the 1997 White Paper for Social Welfare in general and more specifically the section on children in conflict with the law, (ii) to provide a historical overview of the delivery of services to youth in conflict with the law prior to the first democratic elections (1994) in South Africa, (iii) to examine what the concept of &lsquo / integrated service delivery&rsquo / means to the different role-players at the One Stop Child Justice Centre, (iv) to examine the existing resources (human, financial and other) for successful implementation of the policy, (v) to examine whether there are procedures in place to encourage co-operation among stakeholders at the One Stop Child Justice Centre, (vi) to examine the successes, challenges and opportunities presented by the implementation of this policy at the One Stop Child Justice Centre and, (vii) to identify gaps between policy and implementation and make recommendations towards more successful implementation. Detailed semi-structured interviews were conducted with the Centre Manager and senior representatives of all the services involved (Social Development, the SAPS, Magistrates, the Probation Service, and Prosecutors). The interview questions focus mainly on implementation issues and challenges, but also gather information on the knowledge of the interviewees on the content of the policy.
