Hierdie ondcrsoek is daarop gerig om die invloed van die vader se afsterwe op die onaflianklikheidstrewe_van die setm in puberteit te bepaal. Ten einde 'n beeld te vorm van wat so 'n seun ontbeer, is daar 'n oorsig gegee met betrekking tot die rol wat die vader speel in die ontwikkeling van sy seun.

Doel: Die studie het gepoog om vaders se persepsie en ervaring van uitdagings in hulle verhouding met hul leergestremde kind te verken en te beskryf. Agtergrond: Leergestremdheid is ’n baie algemene probleem by kinders en is bekend vir die negatiewe effek wat dit op die kind self en op die ouers van die kinders uitoefen. Dit blyk dat ’n leergestremde kind addisionele spanning op die ouers plaas. Hierdie studie fokus alleenlik op die vader van ’n leergestremde kind omrede die meeste studies slegs op die moeder-kind-verhouding fokus, aangesien die moeder as die primêre versorger van die kind beskou word. Die navorsingsmetode wat vir hierdie studie gebruik is, was ’n kwalitatiewe navorsingsontwerp. Die populasie het bestaan uit vaders met leergestremde kinders in die ouderdomsgroep van 13 tot 18 jaar en wat as gevolg van intrinsieke oorsake leergestremd is. Die data is aan die hand van semigestruktureerde onderhoude met vyf vaders, asook met ’n groepsgesprek bekom. Die doel was om die vaders se ervaring van hulle verhouding met hul leergestremde kind te ondersoek, waarna tematiese analises gebruik is om data saam te stel. Die elemente van kwalitatiewe verkennende en beskrywende teorie het as breër raamwerk vir die studie gedien. Bevindings: Die vaders het hulle verhouding met hul leergestremde kind as baie frustrerend beskryf en gesê dat hulle ook nie ’n goeie verhouding met hul kind het nie. Gevoelens van teleurstelling het primêr betrekking op die onvoldoende verwagtinge wat die vaders vir hulle kind koester. Hulle gevoel dat hulle geen ondersteuning van die skole en van die breër gemeenskap ontvang nie, het ook tot ’n negatiewe ervaring met die leergestremde kind gelei. / MA (Psychology), North-West University, Potchefstroom Campus, 2014

Fatherlessness is a serious problem in South Africa and statistics show a high rate of children growing up without parents and particularly without a biological father. An estimated nine million children in South Africa are growing up without a father (Statistics South Africa [StatsSA], 2010). Statistics South Africa (StatsSA) (2010) highlights the systematic disappearance of the traditional family structure among South African families. According to their statistics, only 27% of South African children live with their biological parents, which is a further indication of the increasing number of children in South Africa that come from fatherless homes. In light of the above, the primary goal of the study was to determine teachers‟ perceptions on the impact of fatherlessness on child development. A literature review was undertaken to analyse and describe the effect of fatherlessness on child development from Bronfenbrenner‟s bio-ecosystemic perspective. Secondly, a case study was conducted to qualitatively explore the perceptions of primary school teachers on the effect of fatherlessness on child development. The data was gathered by means of focus group interviews and analysed. The following findings arose from the empirical study: * Fatherlessness has an effect on virtually all facets of child development (emotional, social, moral, spiritual, cognitive and physical). * Fatherlessness implies the absence of a father, whether it is because of death, physical absence (lives and works elsewhere), a lack of involvement (the so-called present-absent father) or that the identity of the father is unknown. * Fatherless learners need special intervention strategies to support their development. * The types of intervention strategies include emotional support, opportunities for male gender role identification and community awareness projects on fatherlessness. * Aside from the material support some teachers offer to the learners, the school does not provide any formal support to fatherless learners. Recommendations are made, in accordance with the findings, in regard to the support of fatherless learners. / MEd (Learner Support), North-West University, Potchefstroom Campus, 2015

Instagram is one of the main social platforms for business promotion. Millions of potential customers and endless visual marketing opportunities makes Instagram a perfect place to increase online sales. There are many tools and mechanisms to promote brands on Instagram such as paid advertising or using a pre-generated set of popular hashtags. In this regard, the presence and content of users’ comments becomes an important socio-psychological factor in the motivation to buy or use a product or service. The goal of this degree project is to investigate natural language processing techniques applied to users’ comments on Instagram in order to determine a new algorithm that will include content analysis to the list of feed ranking factors. As it is now, the user has to read through posts on Instagram to get an idea of the quality of a product or service. Therefore, a way to classify and rank products and services is needed. We propose a new algorithm called "Wed 2.0" that can assist consumers in their search of wedding services and products on Instagram. Data mining techniques and sentiment analysis are used to define the mood of the comments and structure user opinions as well as to rank accounts based on this knowledge.

Background Daily, companies generate enormous amounts of customer support tickets which are grouped and placed in specialised queues, based on some characteristics, from where they are resolved by the customer support personnel (CSP) on a first-in-first-out basis. Given that these tickets require different levels of urgency, a logical next step to improving the effectiveness of the CSPs is to prioritise the tickets based on business policies. Among the several heuristics that can be used in prioritising tickets is sentiment polarity. Objectives This study investigates how machine learning methods and natural language techniques can be leveraged to automatically predict the sentiment polarity of customer support tickets using. Methods Using a formal experiment, the study examines how well Support Vector Machine (SVM), Naive Bayes (NB) and Logistic Regression (LR) based sentiment polarity prediction models built for the product and movie reviews, can be used to make sentiment predictions on email support tickets. Due to the limited size of annotated email support tickets, Valence Aware Dictionary and sEntiment Reasoner (VADER) and cluster ensemble - using k-means, affinity propagation and spectral clustering, is investigated for making sentiment polarity prediction. Results Compared to NB and LR, SVM performs better, scoring an average f1-score of .71 whereas NB scores least with a .62 f1-score. SVM, combined with the presence vector, outperformed the frequency and TF-IDF vectors with an f1-score of .73 while NB records an f1-score of .63. Given an average f1-score of .23, the models transferred from the movie and product reviews performed inadequately even when compared with a dummy classifier with an f1-score average of .55. Finally, the cluster ensemble method outperformed VADER with an f1-score of .61 and .53 respectively. Conclusions Given the results, SVM, combined with a presence vector of bigrams and trigrams is a candidate solution for extracting sentiments from email support tickets. Additionally, transferring sentiment models from the movie and product reviews domain to the email support tickets is not possible. Finally, given that there exists a limited dataset for conducting sentiment analysis studies in the Swedish and the customer support context, a cluster ensemble is recommended as a sample selection method for generating annotated data.
