La période allant de 1887 aux indépendances (1960) permet d’aborder la question de la justice en Afrique occidentale française en mettant en évidence la transformation des règles et de l’exercice de la justice, ainsi que la rencontre entre le système occidental et le pluralisme juridique local. Au Sénégal, comme dans les autres territoires de l’Afrique occidentale française, l’évolution juridique et judiciaire révèle l’opposition de deux tendances : celle de l’assimilation et celle de l’adaptation. Dans le cadre de cette confrontation, des juridictions non connues en métropole sont créées dans les colonies afin de remédier à l’insuffisance de personnel et des moyens financiers des juridictions. Pour ces mêmes raisons, la collégialité demeure très rare et la justice est souvent organisée autour d’un seul juge qui prend en charge la poursuite, l’instruction et le jugement. L’organisation de la justice pénale indigène, mise en place en 1903, répond avec pragmatisme à la volonté de maintenir les institutions indigènes. Toutefois, le désir d’assimilation conduit à y réaliser des réformes qui tendent à affaiblir les institutions indigènes. / The period going from 1887 to the independences (1960) allows us to approach the question of the justice in French West Africa by highlighting the transformation of rules and the exercise of the justice, as well as the meeting between the Western system and the local legal pluralism. In Senegal as in the other territories of the French West Africa, the legal and judicial evolution reveals the opposition between two trends: that of the assimilation and that of the adaptation. Within the framework of this confrontation, jurisdictions that are unknown in the mainland France are created in the colonies in order to remedy with the lack of staff and with the financial means of the jurisdictions. For these same reasons the collegiality remains very rare and the justice is often organized around only one judge who is in charge of the pursuit, the investigation and the judgement. The organisation of the native penal justice set up in 1903, practically meets with the will of keeping the native institutions. However, the desire of assimilation leads to achieve around it reforms which tend to weaken the native institutions.

Reaktiv programmering är ett programmeringsparadigm som har utvecklats för att underlätta byggande av händelsedrivna reaktiva applikationer. Dess förespråkare hävdar att det kan leda till ökad kodkvalitet, men få studier har utförts för att underbygga dessa påståenden empiriskt. Denna studie syftade till att undersöka skillnaden i kodkomplexitet och kodläsbarhet mellan traditionell imperativ programmering och reaktiv programmering. En fallstudie utfördes där koden för ett befintligt öppen källkodsprojekt omstrukturerades, vilket resulterade i en imperativ version och en reaktiv version av samma kod. Verktyg för statisk källkodsanalys användes för att undersöka om några förändringar i kodläsbarhet och kodkomplexitet kunde upptäckas. Vidare diskuteras huruvida resultaten av den senaste teknikens läsbarhetsmätvärden ger en exakt förutsägelse av kodläsbarheten i reaktiva kodbaser, eller om kanske dessa mätvärden behöver modifieras för att göra dem tillämpliga på det reaktiva paradigmet. Våra resultat visar att läsbarheten påverkades negativt av reaktiv programmering när den mättes med senaste teknikens läsbarhetsmätvärden, men kodkomplexiteten minskades betydligt. / Reactive programming is a programming paradigm that has been proposed to facilitate building eventdriven reactive applications. It is claimed by its proponents to increase code quality, but few studies have been performed to substantiate these claims empirically. This study aimed to explore the difference in code complexity and code readability between traditional imperative programming and reactive programming. A case study was performed where the code of an existing open source project was restructured, resulting in an imperative version and a reactive version of the same code. Static analysis tools were used to investigate if any changes in code readability and code complexity could be detected. Furthermore, it is discussed whether the results of the state-of-the-art readability metrics give an accurate prediction of code readability in reactive code bases, or if perhaps these metrics need to be modified to make them applicable to the reactive paradigm. Our findings show that the readability was negatively affected by reactive programming when measured with state-of the-art readability metrics, however code complexity was decreased significantly

Diploma thesis "Self-regulation Motives of Czech Journalists along with Routine Professional Decision" deals with regulators which show up in daily pofessional work of journalists at present, i.e. in period when this diploma thesis was written. Motives and influences of each regulator are examined in sample of three nationwide publishers - Mlada fronta Dnes, Pravo and Lidove noviny. Sixteen journalists participated in this survey, which was made in period from March, 16th 2008 to May, 5th 2008. This work is focused on Codes of Conduct (Codes of Ethics) of the surveyed publishers and explores their effects on professional manners of each editor. Furthermore, this diploma thesis is also about journalists personal professional limits which work as personal self-regulators. It investigates what is excusable for editors and what is not, within the survey. This diploma thesis answers on question which regulators influence editors and how editors react. In conclusion this work also deals with self-regulation aspects, if they are considered important by editors or not. This diploma thesis compares results among the above mentioned surveyed publishers as well as within the hierarchy of each publisher.

Syftet med detta projekt har varit att skapa en jämförelse mellan två olika webbutvecklingsmetoder, no code och klassisk webbprogrammering, jämförelsen har skapats via en fallstudie hos företaget Lyxrummet där två webbutiker har skapats med dessa två olika metoder. No code-plattformen som använts har varit Wordpress och den klassiska webbprogrammerings metoden som använts har varit med språken PHP, HTML och CSS. För att kunna få fram resultatet av jämförelsen mellan webbutikerna så har användartester med 8 deltagare utförts samt mätningar på utvecklingstiden och kodrader. Slut resultatet visade att klassisk webbprogrammering var en mer lockande sida för deltagarna från användartestet men no code webbutiken var en snabbare och billigare variant för utveckling då ingen teknisk kunskap krävs. / The purpose of this project has been to create a comparison between the two different web development methods, no code and classical web development. The comparing has been done through a case study with the company Lyxrummet where two web shops have been created with these two methods. The no code platform that has been used is WordPress who is a leading platform for web development, and for the classical web development the language PHP, HTML, and CSS has been used. To be able to reach a result by the comprising between the web shops user testing have been done of 8 participates and measurement of the development time and code lines. The finishing result showed that the classical web developed web shop was the most liked by the user testing, but the no code web shop was a faster and cheaper alternative for web development because no technical knowledge person is needed.

In South Africa, the medium-of-instruction (MOI) debate has continued to demand the attention of educators and academics, particularly after the promulgation of the 1997 multilingual language-in-education (LIE) policy and the introduction of the OBE-NCS curriculum in the schools. Using a survey questionnaire, classroom observations and focused interviews, this study aims at establishing how teachers in selected urban and rural high schools in the Mthatha District understand, interpret and implement MOI policies within their practice. It also seeks to establish reasons for implementing the MOI policies in the ways they do. The study utilizes Phillipson’s English Linguistic Imperialism Theory, Brock-Utne’s Qualification Analysis, and Vygotsky’s Social Constructivism to explain the findings. The main findings of the study are that MOI policies are not implemented uniformly in urban and rural contexts or within each context. Learner linguistic profiles, mismatch between a teacher’s home language (HL) and that of his/her learners, the subject being offered, the need to promote understanding of content, teachers’ understandings, misconceptions and beliefs about the role of language in education: all these were found to be factors which may influence a teacher’s language choice during lesson delivery. Generally, teachers endorse the use of English as a language of learning and teaching (LOLT) at high school, together with the learners’ HL. Although some teachers believe that they use English mainly for teaching, indigenous languages are also used extensively, especially in rural and township schools; code-switching, code-mixing, translation, repetition, and township lingo all make the curriculum more accessible to learners. The anomaly is that assessments are conducted only in English, even in contexts in which teaching has been mainly in code-switching mode. An English-only policy was employed in the following situations: in a desegregated urban school; in a rural high school where there was a mismatch between the teacher’s HL and that of his learners; and also in a rural high school where English was offered as a subject. The most cited reasons for using English only as an LOLT were: school language policy, teachers seeing themselves as language role models, the use of English as a LOLT at tertiary level, and past teacher training experiences. The study concludes that the major factors influencing school language policies in a multilingual country such as South Africa are the school context and the teacher and learner profiles. In addition, teaching and assessing learners in languages with which they are familiar, as well as using interactive teaching strategies, would develop learner proficiency, adaptability and creative qualifications, resulting in an improved quality of education. / Thesis (PhD)--University of Pretoria, 2011. / Education Management and Policy Studies / unrestricted

In this study the linguistic situation of Gibraltar has been investigated, especially the phenomenon of the Llanito, that is, a linguistic variety that is the result of the intense contact between the English and Spanish languages in this bilingual territory. An attempt has been made to answer the following questions: When and why do Llanito speakers change languages? Is it about mixing or alternating code? Which of these two phenomena is the most frequent? How is the situation of Llanito today? In order to achieve the objectives of the study, an analysis of 10 interviews conducted within the oral history project Bordering on Britishness has been done using the qualitative method with some elements of the quantitative method. Based on the analysis, it can be seen that Llanito is in good condition in Gibraltar. The interviewees used Llanito in many different situations, among others, to talk about the circumstances of some events they were describing or to tell anecdotes. Regarding the code change, code mixing is more frequent than code alternation. The interviewees change the language very easily and naturally. One can see that the whole process is normal for them. Llanito remains the foundation of Gibraltarian identity and the differentiating element before the English and the Spanish.

Over the past few years there is an increase in globalization and construction industry companies are becoming more aware of the environmental and social aspects in construction projects. Companies have to make a profit and carry out an obligation towards the community. The reason for introducing codes of conduct is to ensure that companies and persons within the construction industry become more socially responsible and adopt it into their daily businesses due to community pressures. It is essential to enforce codes of conduct throughout the construction industry professions, including all stakeholders and team members within the construction industry. This study has sought to determine the main reasons why some quantity surveyors might not always apply the code of conduct in an ethical and professional manner, as well as to identify possible ways how the code of conduct can be improved, be upheld and implemented more successfully in South Africa. Questionnaires were used to collect data from some quantity surveyors in South Africa. The aim of the questionnaire was to identify how some quantity surveyors implement the code of conduct, where the possible gaps in the code of conduct are and how the current code of conduct can be improved. The data determined that the code of conduct needs to be regularly improved in order to stay up to date with current ethical situations that quantity surveyors face daily in South Africa, as well as that some quantity surveyors have a lack of education and proper understanding of the codes of conduct, lack of keeping up to date with the Code and the guidance in which they serve. / Dissertation (MSc)--University of Pretoria, 2020. / Construction Economics / MSc (Quantity Surveying) / Unrestricted

In distributed heterogeneous systems the partitioning of application software to be executed in a distributed fashion is a challenge by itself. The task of code partitioning for distributed processing involves partitioning the code into clusters and mapping those code clusters to the individual processing elements interconnected through a high speed network. Code generation is the process of converting the code partitions into individually executable code clusters and satisfying the code dependencies by adding communication primitives to send and receive data between dependent code clusters. In this work, we describe a generalized framework for automatic code partitioning and code generation for distributed heterogeneous systems. A model for system level design and synthesis using transaction level models has also been developed and is presented. The application programs along with the partition primitives are converted into independently executable concrete implementations. The process consists of two steps, first translating the primitives of the application program into equivalent code clusters, and then scheduling the implementations of these code clusters according to the inherent data dependencies. Further, the original source code needs to be reverse engineered in order to create a meta-data table describing the program elements and dependency trees. The data gathered, is used along with Parallel Virtual Machine (PVM) primitives for enabling the communication between the partitioned programs in the distributed environment. The framework consists of profiling tools, partitioning methodology, architectural exploration and cost analysis tools. The partitioning algorithm is based on clustering, in which the code clusters are created to minimize communication overhead represented as data transfers in task graph for the code. The proposed approach has been implemented and tested for different applications and compared with simulated annealing and tabu search based partitioning algorithms. The objective of partitioning is to minimize the communication overhead. While the proposed approach performs comparably with simulated annealing and better than tabu search based approaches in most cases in terms of communication overhead reduction, it is conclusively faster than simulated annealing and tabu search by an order of magnitude as indicated by simulation results. The proposed framework for system level design/synthesis provides an end to end rapid prototyping approach for aiding in architectural exploration and design optimization. The level of abstraction in the design phase can be fine tuned using transaction level models.
