“A Help to Help Yourself” : A study on feedback and error corrections in Swedish upper-secondary students’ English essaysLindqvist, Angela January 2007 (has links)
The purpose of this essay is to investigate different types of feedback and how they are used in schools, and to see which of them are preferred when it comes to error correction. Feedback is used in schools every day even though it is difficult to know if students really learn from it. Students tend to only glance briefly at the paper or test when it is returned and then throw it away. They are interested in how they scored but not really in how to improve their errors until next time. In this study, students wrote essays which were corrected with four different types of feedback and handed back to the students. The students got a chance to revise them and then the result was analyzed. The students were also given a questionnaire in order for me to find out what kind of feedback they liked the most and compare it to the result of the essay corrections. The different feedback types worked well with different students in general, although, underlining with description did not only work best, it was also chosen as the best type by most students. They seemed to think that this type was good for learning something from the feedback. Most students wanted to look for errors themselves instead of getting the correct answer from the teacher.

Identification d'indicateurs de risque des populations victimes de conflits par imagerie satellitaire études de cas : le nord de l'IrakMubareka, Sarah Betoul January 2008 (has links)
Remote sensing and security, terms which are not usually associated, have found a common platform this decade with the conjuring of the GMOSS network (Global Monitoring for Security and Stability ), whose mandate is to discover new applications for satellite-derived imagery to security issues. This study focuses on human security, concentrating on the characterisation of vulnerable areas to conflict. A time-series of satellite imagery taken from Landsat sensors from 1987 to 2001 and the SRTM mission imagery are used for this purpose over a site in northern Iraq. Human security issues include the exposure to any type of hazard. The region of study is first characterised in order to understand which hazards are and were present in the past for the region of study. The principal hazard for the region of study is armed conflict and the relative field data was analysed to determine the links between geographical indicators and vulnerable areas. This is done through historical research and the study of open-sourced information about disease outbreaks; the movements of refugees and the internally displaced; and humanitarian aid and security issues. These open sources offer information which are not always consistent, objective, or normalized and are therefore difficult to quantify. A method for the rapid mapping and graphing and subsequent analysis of the situation in a region where limited information is available is developed. This information is coupled with population numbers to create a"risk map": A disaggregated matrix of areas most at risk during conflict situations. The results show that describing the risk factor for a population to the hazard conflict depends on three complex indicators: Population density, remoteness and economic diversity. Each of these complex indicators is then derived from Landsat and SRTM imagery and a satellite-driven model is formulated. This model based on satellite imagery is applied to the study site for a temporal study. The output are three 90 m × 90 m resolution grids which describe, at a pixel level, the risk level within the region for each of the dates studies, and the changes which occur in northern Iraq as the result of the Anfal Campaigns. Results show that satellite imagery, with a minimum of processing, can yield indicators for characterising risk in a region. Although by no means a replacement for field data, this technological source, in the absence of local knowledge, can provide users with a starting point in understanding which areas are most at risk within a region. If this data is coupled with open sourced information such as political and cultural discrimination, economy and agricultural practices, a fairly accurate risk map can be generated in the absence of field data.

Community service in Uganda as an alternative to imprisonment: a case study of Masaka and Mukono districtsBirungi, Charles January 2005 (has links)
Magister Artium - MA / Community service as an alternative to imprisonment at its inception was taken up very strongly by the judiciary as part of the reform of the criminal justice system in Uganda. The successful enactment of the Community Service Act, Act no: 5/2000, was an achievement towards the implementation of the programme in the country. However, its implementation as an alternative sentence is currently proceeding at a slow pace. The Ugandan law still allows courts to exercise their discretionary powers with regard to either using prison sentences or community service. Courts still seem to prefer to use imprisonment irrespective of the nature of the offence, thus leading to unwarranted government expenditure and prison overcrowding. An additional problem is that some offenders come out of prison having been negatively affected by their interaction with even more serious offenders. This study was undertaken to establish whether community service as an alternative to imprisonment can be effective with regard to reducing recidivism and to accelerating reconciliation and reintegration of minor offenders back into their communities. / South Africa

Privatisation of prisons and prison services in South AfricaNtsobi, Mfanelo Patrick January 2005 (has links)
Magister Administrationis - MAdmin / The privatization of public prisons has caused much controversy in South Africa as well as internationally. However, it should be noted that the level of resistance to privatisation within the South African context has been minimal by international standards. It is not clear what might have contributed to this quiet approach given the fact that there are many anti-privatisation campaigns driven by the labour movement and civil society groups in South Africa. This research investigation focused on the privatisation of prisons and prison services in South Africa and has explored the various advantages and disadvantages that exist in this respect. / South Africa

Rapid-Chase Theory: The Influence of the Time of Invisible Stimulus Presentation on Movement ControlFlannigan, Jenna Catherine January 2015 (has links)
In the response priming paradigm, a small briefly presented visual stimulus (i.e., prime) is followed by a larger visible stimulus (i.e., mask) that renders the prime invisible and specifies the target location. According to the rapid-chase theory, the initial portion of the movement is dictated by the prime (initiation criterion) while the later portion is dictated by the mask (takeover criterion) and the prime is initially processed independently from the mask (independence criterion). The purpose of the first experiment was to determine if the processing of the prime and mask fit the predictions of the rapid-chase theory when the prime and mask are presented during an ongoing movement. The second experiment was designed to examine the impact of the prime when it is presented at various times throughout the execution of the movement. Participants initiated rapid pointing movements to a center target. On 1/3 of the trials, participants had to correct their movements to the left (or right) target in response to a left-pointing (or right-pointing) mask arrow, which was preceded by a neutral, left-, or right-pointing prime arrow. In Experiment 1, the prime was presented at movement onset and the mask randomly appeared 33, 50, or 67 ms after prime onset. In Experiment 2, the prime followed movement onset with a delay of 17, 33, or 50 ms and the mask was presented 50 ms after prime onset. In both experiments, participants first modified their movements in the direction indicated by the prime before completing their movements to the correct target in the majority of trials; thus, supporting the initiation and takeover criteria. However, the spatial priming effects did not follow the time course predicted by the independence criterion. Overall, the rapid-chase theory does not seem to apply to movement execution, but the prime is still able to influence the movement despite being presented later in the pointing trajectory.

Problématique de l’évaluation neuropsychologique du sujet âgé de bas niveau d’études / Neuropsychological assessment of elderly populations with low-educational levelMokri, Hind 26 November 2013 (has links)
L’impact du niveau d’études sur les performances cognitives est largement connu. Aussi, l’évaluation des sujets de bas ou très bas niveau d’études est un réel challenge pour les cliniciens. D’une part, les outils habituellement utilisés dans le bilan du sujet âgé ne sont pas adaptés aux individus analphabètes ou de bas niveau d’éducation, et, d’autre part, les normes nécessaires à l’interprétation des scores cognitifs ne prennent pas suffisamment en considération cette population de bas niveau scolaire. Ainsi, la question que pose ce travail de thèse est de savoir comment optimiser l’évaluation neuropsychologique de ces sujets de bas niveau scolaires. L’objectif poursuivi par la première étude de cette thèse est de déterminer s’il existe un effet propre du fait de savoir lire et écrire indépendamment de celui de la scolarisation. Pour répondre à cette question, nous avons pu accéder aux données recueillies dans la cohorte mexicaine de Coyoacán qui a la particularité d’avoir un échantillon important de sujets n’ayant jamais été scolarisés. Cette première étude a montré que des sujets n’ayant jamais accédé au système éducatif mais ayant des notions rudimentaires de lecture et d’écriture acquises de manière informelle, ont des performances plus élevées à tous les tests considérés, hormis pour le Set test d’Isaacs (IST), que des sujets ne sachant pas lire et écrire. Ainsi, ces résultats illustrent l’effet des capacités de lecture et d’écriture, un effet distinct de l’effet du niveau de scolarisation. Une seconde difficulté à laquelle doivent faire face les cliniciens est l’absence de normes adaptées aux sujets de bas niveau d’études. Ainsi, un travail autour de l’élaboration de normes adaptées aux sujets de bas niveau d’études a été réalisé dans la cohorte de Coyoacán et nous a permis d’élaborer des normes pour le Mini Mental State Examination (MMSE), le Rappel libre/Rappel indicé 16 items (RL/RI-16) et l’IST, jusque-là inexistantes pour la population âgée mexicaine et qui a la particularité de présenter une forte proportion de sujets de bas niveau d’études. Un second travail de normalisation a été réalisé dans la cohorte AMI, une cohorte menée en milieu rural dans le département de la Gironde dans laquelle la proportion de sujets de bas niveaux est plus élevée qu’en population générale, pour un nouveau test de mémoire visuo-spatiale, le test des gobelets pour lequel nous avons également étudié sa validité dans la détection de la démence. Ces normes classiques, corrigées pour des variables démographiques sont essentielles à l’interprétation des scores cognitifs. Dans le même temps, dans le cas de la démence où l’âge et le niveau d’études sont deux facteurs de risque majeurs, cette pratique habituelle de corriger pour ces variables afin d’établir ou de prédire un diagnostic de démence peut être remise en question. Si des travaux antérieurs ont montré que l’utilisation de scores corrigés diminue la qualité de détection de la démence, la dernière étude de cette thèse a montré qu’il en est de même lorsqu’il s’agit de prédire la démence : les sujets qui deviennent déments à court terme sont mieux classés lorsque les scores ne sont pas corrigés que lorsqu’ils sont corrigés pour l’âge et le niveau d’études. Ainsi, loin de régler le vaste problème de l’évaluation du sujet de bas niveau d’études, cette thèse tente d’apporter des éléments pragmatiques au clinicien sous la forme de tests ou de normes adaptées, mais aussi des éléments de réflexion sur l’utilisation de ces scores. / The effect of education on cognitive performances and neuropsychological assessment outcomes has been well documented so far. Indeed, the assessment of cognitive performance of individuals with low and very low educational level remains a major clinical challenge for several reasons. Firstly, conventional cognitive assessment tools used with elderly patients are not suitable for illiterate or poorly instructed individuals. Secondly, traditional norms used to identify strengths and weaknesses of cognitive performance are not sensible enough to detect cognitive impairments among illiterate or scarcely instructed individuals. Therefore, how to improve the neuropsychological assessment of individuals with low formal educational level is the main research question of this doctoral thesis. To adequately answer to this prior question, four studies have been conducted. The aim of the first study presented in this thesis was to investigate the specific effect of literacy acquisition on cognitive performances independently of education. For this work, we used data collected from the Coyoacán study, a Mexican population-based cohort which presents an important sample of uneducated participants. The main finding of this study was that participants who never attended school but counting with informal literacy abilities, presented better performances for all cognitive tests, except for the Isaacs Set test (IST), compared to their uneducated illiterate counterparts. These findings illustrate the specific effect of literacy skills acquisition on cognitive performances independently of the influence of schooling. The lack of adapted comparative norms is the second major challenge of neuropsychological assessment of individuals with low-educational level. Consequently, our second study aimed at establishing comparative norms for the MMSE, the Free and Cued Selective Reminding Test and the IST, three tests widely used for cognitive evaluation in elderly people. Of note, these norms were specifically established for the Mexican elderly population, which presents a high rate of illiteracy and low-educational level. Finally, a third study aiming at establishing comparative norms for a new visuo-spatial memory-test: the goblets test. For this study, we used data collected from the AMI cohort study which is conducted in rural areas in the South-West of France. Within this third study we also studied the validity of this test in detecting dementia illness. These comparative norms are necessary to interpret cognitive scores. However, as age and education are major risk factors for dementia, correcting for these demographic variables to improve the accuracy of detection or prediction of dementia may be questionable. Consistently with other studies showing that dementia detection accuracy is compromised when corrected scores are used; findings of our last study showed that regarding dementia prediction accuracy, participants developing dementia, in the short term, are better classified when using uncorrected scores for age and education than the corrected ones. To conclude, cognitive assessment of elderly individuals with low-educational level remains still a major clinical barrier to correctly diagnose dementia. However, besides providing clinicians with several pragmatic inputs such as cognitive tests and appropriated comparative norms, we believe that our findings will encourage clinical reflection regarding the use of these scores.

An evaluation of the drugs crime nexus, legalization of drugs, drug enforcement, and drug treatment rehabilitationKeesling, James Richard 01 January 2000 (has links)
Law enforcement agencies are faced with the problem of how to reduce crime in the most economical method possible without violating the law. Since drug offenders also engage in a disproportionate amount of non-drug crime, then drug enforcement is considered as an acceptable general crime control method. Unfortuantely, this is an expensive option because incarcerating offenders is both costly and ony a short-term solution to the problem. A review of existing research examining the prior criminal histories of drug offenders compared to their previous involvement in violent and property crime is conducted to evaluate this relationship.

Parolee and police officer perceptions of prison gang etiology, power, and controlRichert, William Henry 01 January 2006 (has links)
Examines the attitudes and perceptions among parolees, and police officers on why inmates join prison gangs, how powerful they are, and their power and control in prison. Data was gathered from 250 surveys distributed to a group of parolees at an undisclosed southern California municipal police department jail, and 250 surveys distributed to police managers attending the FBI National Academy in Quantico, Virginia. Results of this study validated the hypothesis that there is a significant difference in attitudes and perceptions of parolees and police officers of why inmates join prison gangs and the power and control gang inmates have in prison.
