The study investigated the academic performance of orphaned secondary school learners between the ages of thirteen and eighteen in the Shamavunga Circuit. The study used the qualitative method. This included the sampling of ten orphaned learners from one school in the Shamavunga Circuit. The qualitative component of the study involved sampling three educators and three guardians of orphaned learners from one secondary school in the Shamavunga Circuit. This study was aimed at investigation the perceptions of educators and learners of the academic performance of orphaned learners at secondary schools in the Shamavunga Circuit, Limpopo province. The study found that the educators were of the view that, as compared to their counterparts, orphaned learners are more likely to display unruly behaviour, a lack of concentration and an inability to complete their written schoolwork. The educators also suggested that because the majority of orphaned learners were heading their families (child-headed), there was no one to monitor and supervise them. On the other hand, it has been suggested that the majority of orphaned learners were staying with their caregivers/guardians. The study also revealed that the educators were not well trained in terms of dealing with orphaned learners. In other words they lacked the proper skills and knowledge required to deal with orphaned learners. On the other words, the orphaned learners were of the view that some of the educators were not treating them well as they called them names and they were also not providing them with the support that they should have been receiving from adults who should be playing a parental role in their lives. Furthermore, some of the orphaned learners suggested that the caregivers (guardians) with whom they lived misused their grants for their own benefit. The study also revealed that the guardians of orphaned learners were often not coping and were uneducated. Accordingly, they were unable to adequately meet the needs of these orphaned learners. In conclusion, the study recommended interventions at the school, government as well as the community levels. For example, it is suggested that grandparents (guardians) be provided with support as they were becoming exhausted as a result of having to look after the orphaned learners. It is also suggested that the government build more drop-in centres and orphanages and also provide training for the educators who have to deal with the orphaned learners. / Educational Leadership and Management / M.

English text with English, Northern Sotho and Afrikaans summaries / South Africa has a long and troubled educational history, from pre-colonial education to the fall of apartheid, and eventually the acquisition of equal education for all (Christie, 2006). Many changes took place during this transitional period in the democracy and liberation of the New South Africa by means of pupil-centred classrooms, Curriculum 2005 (Taylor, 1995) and Curriculum and Assessment Policy Statement (CAPS). Although numerous studies have been conducted internationally and in South Africa on underperforming in schools, the focus of this study is to ascertain the key elements of why learners underperform. The study’s aim is to determine the influence of a learner’s socio-economic situation on scholastic performance with references to nutrition, family structure, and parental support of learners in primary schools in Tshwane. In this full dissertation, the researcher found that most of the selected home environmental factors had no significant impact on the selected learners. It was, however, found (as many research already proved) that diet and sleep did have an influence on primary school learner academic performance. In presenting this argument, the theoretical framework, socio-constructivism learning theory, and Maslow’s hierarchy of needs, were used, as socio-constructivism states that although biological factors are a requirement for basic development to emerge, socio-cultural factors are crucial for basic natural processes to develop. Vygotsky’s socio constructivism theory indicates the uniqueness of the social environment and regards socio-cultural background as the primary and determining factor in the development of higher forms of human mental activity such as voluntary attention, intentional memory, logical thought, planning, and problem solving. In conjunction with Vygotsky, Maslow’s hierarchy of needs sets the foundation for this study as it states that in order for a being to move to the next level, the lower level of needs, need to be satisfied first. The objectives of the study were: - to determine what the impact of selected home environment factors on primary school learners’ academic performance is. To determine the relationship between poverty, family structure, and scholastic performance; to determine the influence of the type of dwelling on scholastic performance; to determine the influence nutrition have on a learners’ scholastic performance; and to determine the influence sleep deprivation has on learners’ academic performance. The study used a quantitative approach, and the method included questionnaires that learners in Grade 5, Grade 6, and Grade 7 of the selected school completed anonymously. The study revealed that poverty, family structure, and dwelling type did not have a significant impact on the learners of the selected school. The study did however reveal and confirmed what various other researchers have already found that sleep and nutrition did have an influence on academic performance. It is recommended that specific guidelines should be provided to parents about economical lunchbox ideas. Parents should be supplied with lists of foods best to pack in lunchboxes and food that is not allowed. Schools should further monitor the food provided at tuck shops, as the food provided should be nutritious as well as sustain learners’ energy. Food high in saturated fats and sugar should not be allowed at school tuck shops. Children should also be educated about nutrition and better or alternative choices they can make. Lunches that are supplied as part of the school nutrition program should be monitored to ensure that it is nutritious, low in sodium, and that a variety of fruit and vegetables are included in the meal. Studies have concluded that children should sleep on average nine hours per night. Unfortunately, due to increase in academic pressure and work load, more learners go to bed later. It is therefore recommended that schools adhere to guidelines on the amount of homework given to learners daily. It is further recommended that parents should ensure that their children have a set routine regarding sleep patterns. The use of electronic equipment, such as television, computers, and cellular phones prior to sleeping time should be limited as it affects sleep. Surprisingly, this study has also revealed that some of the data supplied to the school by the parents or guardians and the data that was obtained from the learners did not correlate. It is therefore recommended that schools should be more scrupulous with learner performance data as it could be a possible indicator of household problems or the quality of education. If it is found that the decline is due to quality of education, the school management team should act immediately to assist the necessary educators with the necessary skills to enable better quality of education. A pro-active plan of action should be put in place by the school for those learners whose marks decreased. An educator could talk to the learner and the parents to try and determine the possible causes for the decrease in marks. Remedial classes or remedial exercises should be given to the learners to assist in the areas of need. In addition, if it is determined that the cause is due to home environment factors then necessary assistance should be provided either by the school or other entities. / Afrika Borwa e na le histori ya thuto ye telele gape ya mathata, go tloga go thuto ya pele ga bokoloni go ya go go fedišwa ga kgatelelo le go hwetša mafelelong thuto ya go lekana go bohle (Christie, 2006).

Baie veranderinge het gedurende hierdie oorgangsperiode in die demokrasie en bevryding van die Nuwe Suid-Afrika plaasgevind deur middel van leerdergesentreerde klaskamers, Kurrikulum 2005 (Taylor, 1995) en die Kurrikulum- en Assesseringsbeleidsverklaring (KABV). Hoewel talle studies oor onderprestasie in skole internasionaal en in Suid-Afrika uitgevoer is, is die fokus van hierdie studie om die kernfaktore vas te stel wat tot onderprestasie van leerders lei. Die studie het ten doel om die invloed van ’n leerder se sosioëkonomiese situasie op skolastiese prestasie te bepaal met verwysing na voeding, gesinstruktuur en ouerondersteuning van leerders in primêre skole in Tshwane. In hierdie volledige proefskrif het die navorser bevind dat die meeste geselekteerde tuisomgewingfaktore geen beduidende uitwerking op die geselekteerde leerders gehad het nie. Daar is egter bevind (soos deur baie navorsers bewys is) dat dieet en slaap wel ʼn invloed op primêreskoolleerders se akademiese prestasie gehad het. In die aanbieding van hierdie argument is die teoretiese raamwerk, sosiaal-konstruktivistiese leerteorie en Maslow se behoeftehiërargie gebruik. Sosiaalkonstruktivisme bepaal dat, hoewel biologiese faktore ’n vereiste is sodat basiese ontwikkeling kan plaasvind, sosiaalkulturele faktore deurslaggewend vir die ontwikkeling van basiese natuurlike prosesse is. Vygotsky se teorie oor sosiaalkonstruktivisme dui op die uniekheid van die sosiale omgewing en beskou die sosiaalkulturele agtergrond as die primêre en bepalende faktor in die ontwikkeling van hoër vorms van menslike verstandelike aktiwiteit, soos vrywillige aandag, intensionele geheue, logiese denke, beplanning en probleemoplossing. Tesame met Vygotsky, maak Maslow se behoeftehiërargie die grondslag van hierdie studie uit, aangesien dit bepaal dat, ten einde na die volgende vlak te beweeg, ’n mens se laer vlak van behoeftes eers bevredig moet word. Die doelwitte van die studie was om die volgende te bepaal: watter uitwerking geselekteerde tuisomgewingfaktore op primêreskoolleerders se akademiese prestasie het; die verhouding tussen armoede, gesinstruktuur en skolastiese prestasie; die invloed van die tipe woning op skolastiese prestasie; die invloed wat voeding op ’n leerder se skolastiese prestasie het; en die invloed wat slaapontneming op ’n leerder se akademiese prestasie het. Die studie het ’n kwantitatiewe benadering gebruik, en die metode het vraelyste ingesluit wat leerders in Graad 5, Graad 6 en Graad 7 van die geselekteerde skool anoniem voltooi het. Die studie het aan die lig gebring dat armoede, gesinstruktuur en tipe woning nie ’n beduidende uitwerking op die leerders van die geselekteerde skool gehad het nie. Die studie het egter wel aan die lig gebring en bevestig wat verskeie ander navorsers reeds bevind het: dat slaap en voeding ʼn invloed op akademiese prestasie het. Daar word aanbeveel dat spesifieke riglyne oor ekonomiese kosblik-idees aan ouers verskaf moet word. Ouers behoort voorsien te word van lyste van die beste kossoorte om in kosblikke te pak, en kossoorte wat nie toegelaat word nie. Skole behoort voorts die kos te monitor wat by snoepwinkels te koop aangebied word, aangesien sodanige kos voedsaam moet wees en leerders se energie moet volhou. Kos wat ryk aan versadigde vette en suiker is, behoort nie by skoolsnoepwinkels toegelaat te word nie. Daarbenewens behoort kinders opgevoed te word oor voeding en beter of alternatiewe keuses wat hulle kan maak. Middagetes wat as deel van die skoolvoedingsprogram voorsien word, moet gemonitor word om te verseker dat hulle voedsaam en laag in sout is, en dat ’n verskeidenheid vrugte en groente by die maaltyd ingesluit word. Studies het tot die slotsom gekom dat kinders gemiddeld nege uur per nag behoort te slaap. Ongelukkig, weens ʼn toename in akademiese druk en werklading, gaan al hoe meer leerders later slaap. Daar word dus aanbeveel dat skole riglyne nakom rakende die hoeveelheid huiswerk wat daagliks aan leerders gegee word. Daar word verder aanbeveel dat ouers moet verseker dat hul kinders ’n vaste slaaproetine het. Die gebruik van elektroniese toerusting, soos televisie, rekenaars en selfone voor slaaptyd, behoort beperk te word omdat dit slaap beïnvloed. Dit is verrassend dat die studie ook aan die lig gebring het dat sommige van die data wat deur die ouers of voogde aan die skool verskaf is en die data wat van die leerders bekom is, nie ooreengestem het nie. Daar word dus aanbeveel dat skole meer nougeset met leerderprestasiedata moet omgaan, aangesien dit ’n moontlike aanwyser van huishoudelike probleme of die gehalte van onderwys kan wees. Indien daar bevind word dat die afname as gevolg van die gehalte van onderwys is, moet die skoolbestuurspan onmiddellik optree om opvoeders te help om die nodige vaardighede te verwerf om ’n beter gehalte onderwys moontlik te maak. Die skool behoort ’n proaktiewe plan van aksie in werking te stel vir daardie leerders wie se punte gedaal het. ʼn Opvoeder kan met die leerder en die ouers gesels en probeer vasstel wat die moontlike oorsake vir die daling in punte is. Remediërende klasse of remediërende oefeninge behoort aan die leerders gegee te word om met die behoefteareas te help. Daarbenewens, indien vasgestel word dat die oorsaak tuisomgewingfaktore is, behoort die nodige bystand gegee te word, hetsy deur die skool of ander entiteite. / Educational Studies / M. Ed.

Transformation of the higher education system has come under the spotlight recently. At the core of this debate are issues pertaining to access and throughput rates at universities. Although access has improved significantly, throughput rates remain relatively low especially amongst black students (Council on Higher Education, 2017). The current study aims to explore the learning experiences and academic performance of postgraduate black students at the university of South Africa. Through a qualitative approach that included interviews, a phenomenological research design and critical race theory to gain an insiders perspective. This approach is chosen for its ability to generate rich descriptive and interpretive accounts of events based on the participant’s narratives. The findings revealed that the variation in learning experiences and academic performance was accounted for by background factors rather than student’s own intellectual or academic competencies. / Psychology / M.A. (Psychology with specialisation in Research Consultation)

This research examined the reasons for the differences in the academic performance of school learners, and makes reference to economic, social and cultural capital theory in explaining educational imbalances in society. Many researchers have conducted studies on the factors contributing to the academic performance of learners at various levels of schooling have been undertaken. These researchers have come to the conclusion that the academic performance of learners is affected by numerous factors, namely, gender, age, learners' schooling, family’s socio-economic status, residential area of learners, the medium of instruction in schools, tuition trends, hours spent on studying on a daily basis and accommodation in hostels (Petersen, 2010:15). There is a popular saying in south-western Nigeria, that “if the parents’ financial status is good, the reflection of it will show in the child”. This study is focused on the academic performance of learners at the secondary school level and investigates the influence of economic, social and cultural capital on their academic performance. This study aims to determine which factors contribute to the poor academic performance of rural secondary school learners in south-western Nigeria and then, based on the findings of the research undertaken to make recommendations regarding what could be done to improve the academic performance of these learners. The mixed-methods approach of combining both qualitative and quantitative approaches to accomplish the aims of the research were used. The population consisted of four secondary schools, four school principals, 16 teachers, 40 parents and 120 learners. According to the results of this research, we can see that the social, cultural and economic capital of parents is a powerful determinant with regard to motivating their children’s education. / Educational Studies / D.

In South Africa learners do not achieve as well as their international counterparts on tests of literacy, and language proficiency is often blamed for their poor academic performance. In this study, the relationship between English language proficiency, reading ability and the academic performance of Grade 7 students in submersion contexts was investigated using quantitative methods. The participants of the study were Grade 7 students based in a former Model C school in the South African city of Johannesburg. Their English language proficiency and reading ability were measured by means of The Proficiency test English Second Language: Intermediate level and the Neale Analysis of Reading Ability tests respectively. The students’ performance on these tests was correlated with the students’ average summative assessment results using the Pearson-product moment correlation. Results showed that both English language proficiency and reading ability were significantly correlated with academic performance, with language proficiency having the most robust correlation. These findings indicate that teachers should aim at improving language proficiency by using multilingual teaching strategies that support home language as a cognitive tool. / English Studies / M. A.

國中基測實施迄今已十年，但是各種多元管道仍以國中基測量尺分數作為分發篩選之重要參據，多元能力評量參採比重偏低，國中學生升學競爭壓力未得緩解。本研究透過數學與統計分析的工具，尋找採用學生在校成績的方法，希望能找出更好的方式來代表學生在校三年的學習現況與學習成果，以做為免試升學採計在校成績的參考與依據。 本研究主要目的是要探討如何取決各科在校成績的權重(也就是在每個科目的分數之前乘上一個加權比重係數)，以求得一個新的合成變量(由數個科目分數組成的線性組合)，並用這個新合成變量做為學生在校的“綜合學科能力表現分數”，代表學生在校三年的基本學習能力及程度。 研究方法運用主成份分析與典型相關分析的觀念，但因限制條件設定的範圍與傳統主成分分析及典型相關分析的要求不一致，因此，我們便將所用的研究方法命名為「類主成分分析」與「類典型相關分析」。 研究中，方法主要在比較「類主成分分析」、「主成分分析」、「類典型相關分析」、以及「典型相關分析」四種方法與一般學校常用的「等加權比重」算平均成績的方法之分別；了解這些不同加權機制對同一所學校內學生的學科加權平均分數之成績排名百分比結果，以及與基測排名結果的差異。 「類主成份分析」研究結果發現，各科學科成績中變異數大的科目將獲得較大的權重比例，成為主導學生加權平均成績中舉足輕重的科目。另外；運用「類典型相關分析法」所求得的典型相關係數，其結果與傳統典型相關分析法以及使用最佳數值分析軟體(GAMS)所得的典型相關係數完全相同。 本研究最重要的貢獻之一，是我們在「類典型相關分析法」中證明並推導出一個求得各科權重的公式，只要使用此公式代入簡單的MATLAB程式，其所得的權重結果與最佳化數值分析軟體(GAMS)所得的結果完全相同，但花費的計算時間及成本卻遠少於GAMS所需，是一個求權重極便捷的方法，讀者可以在本論文附錄7.5.2或政大應數系網站上下載此程式。本研究最後結論也發現，類主成份分析的變異解釋率是所有方法中較高的；與基測總分結果較相近的則是類典型相關分析所得的權重機制；而等加權方法所得的排名結果則與基測排名結果差異最小。 / The BCTEST (Basic Competence Test) for junior high school students has been implemented for ten years, however, the screenings for a variety of entrance programs are still based on the scale scores of the BCTEST with a low proportion of multi-intelligence. Hence, the competitive entrance pressure for junior high school students remains un-relieved. In view of this, via mathematics and statistics, this study is to explore an alternative approach which can not only reflect students' in-school grade, their learning situations and achievements but also represent a reference for entering senior high schools and junior colleges without entrance examinations. The purpose of this study is to determine the different weightings of five learning subjects (that is, multiply the score of each subject by a weighted coefficient) and acquire a new composite variable from the linear combinations of five learning subjects. Then, use this new composite variable as the synthetic score of students' in-school academic performance. Principal Component Analysis and Canonical Correlation Analysis are used in this study. Due to inconsistent restraints, the other two approaches we use are based on the concept of previously mentioned methodologies and denominated Principal Component Type of Analysis and Canonical Correlation Type of Analysis. In the study, we compare with the different results of Principal Component Analysis, Principal Component Type of Analysis, Canonical Correlation Analysis, Canonical Correlation Type of Analysis and identical weighted method to realize how these different weighted schemes affect the rankings of students from the same school on both their weighted in-school grade and scores of the BCTEST (Basic Competence Test). The outcomes of Principal Component Type of Analysis show that subjects with greater variance acquire larger weightings and play a dominant role in weighted in-school grade. Moreover, the correlation coefficients of Canonical Correlation Type of Analysis are completely the same as the ones of Canonical Correlation Analysis and GAMS. One of the most important contributions in this study is we have proven and derived a formula to acquire different weightings of five learning subjects by using Canonical Correlation Type of Analysis. The acquired weightings are completely the same as the ones of GAMS with less time consuming. Readers can download this program in appendix 7.5.2 or from the website of Department of Mathematical Sciences, National Chengchi University(NCCU). We have also found that, the explanation rate of variance obtained from Principal Component Type of Analysis is the highest; the weighted scheme of Canonical Correlation Type of Analysis is more similar to the scores of the BCTEST; the difference of the rankings between identical weighted method and the BCTEST is the smallest.

實施十二年國民基本教育，目的是為促進學生五育均衡發展，兼顧國中學習品質及日常生活表現。由於各校對成績的評分標準與評分方式皆不相同，因此如何使在校成績採計達到公平性將成為一項重要的問題。 戴岑熹(2011) 考慮了國中在校綜合學科分數與基測總分間的相關性，以決定在校各學科的權重。而本研究延伸其概念與方法，將基測各科量尺分數考慮進來，於在校綜合學科分數與基測綜合量尺分數的關聯性最密切的情況下，分析各學科權重的取決方式，希望能找出較理想的模式來代表學生在校三年的整體學習表現與成果，以做為免試升學採計在校成績的參考與依據。 本文的研究方法是運用典型相關分析的理論，但因權重的限制條件與傳統典型相關分析的要求不同，因此，便將其命名為「類典型相關分析」。在類典型相關分析中，我們證明了在校各學科分數及基測各科量尺分數的最佳權重，可先透過典型相關分析求得典型相關向量，若有必要的話，使用Rao-Ghangurad 方法加以修正，最後，再將所獲得的非負典型相關向量正規化，即可獲得所要的結果，這是一個求最佳權重向量極便捷的途徑。在實例分析方面，我們發現了一個有趣的現象，即在校學科分數與基測考科量尺分數的最佳權重向量相當接近，即名稱相同的學科與考科幾乎有相同的權重。在比較了幾個權重分配方式不同的在校綜合學科分數後，我們也發現一般學校常用的等加權模式，其表現結果也頗優異。 / The purpose of implementing the twelve-year compulsory education is to promote the balanced development of learning in students, taking into account their learning quality and normal daily performances in school. As the evaluation standard and method vary among schools, achieving fairness in calculating in-school grades has become an important issue. Dai (2011) considered the correlations between the scores of in-school academic performance and the total score of the BCTEST for junior high schools, which decided to the weightings of all learning subjects. This study extended his concept and method, and took into account the scale scores of all learning subjects. In the closest case of the weightings of all learning subjects and find out the correlations between the scores of in-school academic performance and the BCTEST, and analyse the weightings of all learning subjects. We hope the study can find a better approach that can not only reflect students’ learning situations and achievements for the three years in school but also provide a reference for the evaluation of entering senior high schools without entrance examinations. The research method in this paper employs the theory of canonical correlation analysis.However, due to that fact that weight restrictions are different from the requirements of canonical correlation analysis, it is named as the canonical correlation analysis type approach. In the canonical correlation analysis type approach, we proved that the optimal weights for school subject score and test subject score scales can be obtained by finding the canonical correlation vectors using canonical correlation analysis. Then the Rao-Ghangurad method can further be used for amending, if needed. Finally, the nonnegative canonical correlation vectors generated would be normalized to get the desired result. It is an extremely convenient way to obtain the optimal weight vector. In the case study, we found an interesting phenomenon as follows: When the optimal weight vectors for school subject score and test subject score scales were very close, subjects and tests of the same name had almost the same weight. After comparing several comprehensive school subject scores of different weight distribution, we also found that the results of the equal weighting model commonly used in schools also showed quite good results.

El objetivo de esta tesis es predecir el rendimiento de los estudiantes de doctorado en la Universidad de Girona según características personales (background), actitudinales y de redes sociales de los estudiantes. La población estudiada son estudiantes de tercer y cuarto curso de doctorado y sus directores de tesis doctoral. Para obtener los datos se ha diseño un cuestionario web especificando sus ventajas y teniendo en cuenta algunos problemas tradicionales de no cobertura o no respuesta. El cuestionario web se hizo debido a la complejidad que comportan de las preguntas de red social. El cuestionario electrónico permite, mediante una serie de instrucciones, reducir el tiempo para responder y hacerlo menos cargado. Este cuestionario web, además es auto administrado, lo cual nos permite, según la literatura, unas respuestas mas honestas que cuestionario con encuestador.Se analiza la calidad de las preguntas de red social en cuestionario web para datos egocéntricos. Para eso se calcula la fiabilidad y la validez de este tipo de preguntas, por primera vez a través del modelo Multirasgo Multimétodo (Multitrait Multimethod). Al ser datos egocéntricos, se pueden considerar jerárquicos, y por primera vez se una un modelo Multirasgo Multimétodo Multinivel (multilevel Multitrait Multimethod). Las la fiabilidad y validez se pueden obtener a nivel individual (within group component) o a nivel de grupo (between group component) y se usan para llevar a cabo un meta-análisis con otras universidades europeas para analizar ciertas características de diseño del cuestionario. Estas características analizan si para preguntas de red social hechas en cuestionarios web son más fiables y validas hechas "by questions" o "by alters", si son presentes todas las etiquetas de frecuencia para los ítems o solo la del inicio y final, o si es mejor que el diseño del cuestionario esté en con color o blanco y negro.También se analiza la calidad de la red social en conjunto, en este caso específico son los grupos de investigación de la universidad. Se tratan los problemas de los datos ausentes en las redes completas. Se propone una nueva alternativa a la solución típica de la red egocéntrica o los respondientes proxies. Esta nueva alternativa la hemos nombrado "Nosduocentered Network" (red Nosduocentrada), se basa en dos actores centrales en una red. Estimando modelos de regresión, esta "Nosduocentered network" tiene mas poder predictivo para el rendimiento de los estudiantes de doctorado que la red egocéntrica.Además se corrigen las correlaciones de las variables actitudinales por atenuación debido al pequeño tamaño muestral. Finalmente, se hacen regresiones de los tres tipos de variables (background, actitudinales y de red social) y luego se combinan para analizar cual para predice mejor el rendimiento (según publicaciones académicas) de los estudiantes de doctorado. Los resultados nos llevan a predecir el rendimiento académico de los estudiantes de doctorado depende de variables personales (background) i actitudinales. Asimismo, se comparan los resultados obtenidos con otros estudios publicados. / The aim of this Doctoral Thesis is to predict the PhD students' academic performance in the University of Girona from characteristics of their research group understood as a social network and from background and attitudinal characteristics of the PhD student.The data collection was done through web survey, regarding the traditional problems related to coverage and response errors. Web survey was made in order to reduce the complexity of social network questions.The quality of social network questions for questionnaires with egocentered data is analyzed. For this, reliability and validity of this kind of questions are computed, for first time using a Multilevel Multitrait-Multimethod approach. Data are egocentered and thus hierarchy can be used. Reliability and validity can be obtained in an individual level (within group component) or group level (between group component), which are used for carrying out a meta analysis with other European universities. We study if social network questions asked in web questionnaires are more reliable and valid done "by questions" or "by alters", if the frequency labels are present or not and if the best questionnaire design is plane or graphical.Social network as a whole is also studied, in this case are the research groups in the University of Girona. There is a proposal for the missing data problem in complete networks, different from the egocentered network. This new network structure is called "Nosduocentered Network", which is based in two central actors in a network. Regression model estimations explain that this network has more predictive power in order to predict the academic performance for PhD students.Finally, regression models with background, attitudinal and social network variables are done. Then, we combine the regressions in order to specify the best combination which predicts the PhD student's performance (according to academic publications) best. According to the results, the academic performance depends on background and attitudinal variables. Also, a comparison of results from other published studies is done.

Aquesta tesi forma part d'un projecte destinat a predir el rendiment acadèmic dels estudiants de doctorat portat a terme per l'INSOC (International Network on Social Capital and Performance). El grup de recerca INSOC està format per les universitats de Girona (Espanya), Ljubljana (Eslovènia), Giessen (Alemanya) i Ghent (Bèlgica). El primer objectiu d'aquesta tesi és desenvolupar anàlisis quantitatius comparatius sobre el rendiment acadèmic dels estudiants de doctorat entre Espanya, Eslovènia i Alemanya a partir dels resultats individuals del rendiment acadèmic obtinguts de cada una de les universitats. La naturalesa internacional del grup de recerca implica la recerca comparativa. Vam utilitzar variables personal, actitudinals i de xarxa per predir el rendiment. El segon objectiu d'aquesta tesi és entendre de manera qualitativa perquè les variables de xarxa no ajuden quantitativament a predir el rendiment a la universitat de Girona (Espanya). En el capítol 1, definim conceptes relacionats amb el rendiment i donam un llistat de cada una de les variables independents (variables de xarxa, personals i actitudinals), resumint la lliteratura. Finalment, explicam com s'organitzen els estudis de doctorat a cada un dels diferents països. A partir d'aquestes definicions teòriques, en els pròxims capítols, primer presentarem els qüestionaris utilitzats a Espanya, Eslovènia i Alemanya per mesurar aquests diferents tipus de variables. Després, compararem les variables que són relevants per predir el rendiment dels estudiants de doctorat a cada país. Després d'això, fixarem diferents models de regressió per predir el rendiment entre països. En tots aquests models les variables de xarxa fallen a predir el rendiment a la Universitat de Girona. Finalment, utilitzem estudis qualitatius per entendre aquests resultats inesperats. En el capítol 2, expliquem com hem dissenyat i conduït els qüestionaris en els diferents països amb l'objectiu d'explicar el rendiment dels estudiants de doctorat obtinguts a Espanya, Eslovènia i Alemanya. En el capítol 3, cream indicadors comparables però apareixen problemes de comparabilitat en preguntes particulars a Espanya, Eslovènia i Alemanya. En aquest capítol expliquem com utilitzem les variables dels tres països per crear indicadors comparables. Aquest pas és molt important perquè el principal objectiu del grup de recerca INSOC és comparar el rendiment dels estudiants de doctorat entre els diferents països. En el capítol 4 comparem models de regressió obtinguts de predir el rendiment dels estudiants de doctorat a les universitats de Girona (Espanya) i Eslovènia. Les variables són característiques dels grups de recerca dels estudiants de doctorat enteses com una xarxa social egocèntrica, característiques personals i actitudinals dels estudiants de doctorat i algunes carecterístiques dels directors. Vam trobar que les variables de xarxa egocèntriques no predien el rendiment a la Universitat de Girona. En el capítol 5, comparem dades eslovenes, espanyoles i alemnayes, seguint la metodologia del capítol 4. Concluïm que el cas alemany és molt diferent. El poder predictiu de les variables de xarxa no millora. En el capítol 6 el grup de recerca dels estudiants de doctorat és entès com una xarxa duocèntrica (Coromina et al., 2008), amb l'objectiu d'obtendre informació de la relació mútua entre els estudiants i els seus directors i els contactes d'ambdós amb els altres de la xarxa. La inclusió de la xarxa duocèntrica no millora el poder predictiu del model de regressió utilitzant les variales egocèntriques de xarxa. El capítol 7 pretèn entendre perquè les variables de xarxa no predeixen el rendiment a la Universitat de Girona. Utilitzem el mètode mixte, esperant que l'estudi qualitatiu pugui cobrir les raons de perquè la qualitat de la xarxa falla en la qualitat del treball dels estudiants. Per recollir dades per l'estudi qualitatiu utilitzem entrevistes en profunditat. / This thesis belongs to a wider project designed to predict PhD students' academic performance carried out by the INSOC (International Network on Social Capital and Performance). The INSOC research group is composed by the universities of Girona (Spain), Ljubljana (Slovenia), Giessen (Germany) and Ghent (Belgium). The first aim of this thesis is to develop quantitative comparative analyses about the PhD students' academic performance across Spain, Slovenia and Germany from the individual academic performance results obtained in each university member. The international nature of the research group implies that we strongly emphasize comparative research. We use together background variables, attitudinal variables and social network variables for predicting performance. The second aim of this thesis is to qualitatively understand why network variables fail to quantitatively predict performance in the University of Girona (Spain). Thus, this thesis fit into the multimethod tradition. In Chapter 1, we define concepts related with performance and we give a list of each of the independent variables (social network, background and attitudinal variables) with a literature summary. Finally, we explain how PhD studies are organaized in the different countries. Drawing from these theoretical explanations, in the next chapters we first present the questionnaires used in Spain, Slovenia and Germany to measure these different types of variables. Then, we compare the variables which are relevant in order to predict PhD student performance in each country. After that, we fit alternative regression models to predict performance across countries. In all these models network variables fail to predict performance in the University of Girona. Finally, we use a qualitative study to understand this unexpected result. In Chapter 2, we explain how we designed and conducted a survey in the different countries with the aim of explaining the PhD students' performance obtained in Spain, Slovenia and Germany. In Chapter 3, we create comparable indicators wherever some comparability problems arose with particular questions in Spain, Slovenia and Germany. In this chapter we explain how we used all three countries' variables in order to create comparable indicators. This step is very important because the main goal of the INSOC research group is to compare the PhD student's performance between the different countries. In Chapter 4 we compare regression models obtained to predict PhD students' academic performance in the universities of Girona (Spain) and Slovenia. Explanatory variables are characteristics of PhD student's research group understood as an egocentered social network, background and attitudinal characteristics of the PhD students and some characteristics of the supervisors. We find that egocentered network variables do not predict performance in the University of Girona. In Chapter 5 we compare the Slovenian, Spanish and German data, following the methodology used in Chapter 4. We conclude that the German case is very different. Predictive power of network variables does not improve. In Chapter 6 the PhD student's research group is understood as a duocentered social network (Coromina et al., 2008), in order to obtain information regarding the mutual relationship between PhD students and their supervisor and the ties of both to their alters in the network. The inclusion of duocentered network variables does not improve the predictive power of the regression model using egocentered network variables. Chapter 7 attempts to understand why networks fail to predict performance in the University of Girona. Using the mixed method approach, we expect that a qualitative study can uncover the reasons why the quality of the networks fails to translate into the quality of the students' work. For data collection in the qualitative research we used in-depth interviews.
