Personality of software engineering professionals has been a continuous element of interest in academic research. Researchers have applied different models of personality analysis in various software engineering areas to identify improvement points, to promote job satisfaction and to better organize teams. Among these models, we can highlight the MBTI and BIG Five. This work aims to conduct a study to evaluate personality models applied in software engineering and to understand how human personality influences software quality. Two controlled experiments were performed, the first in industry, in IT department of a private higher education institution and the second in an advanced programming discipline in academy. For both experiments, the quality of software individually produced by each participant was evaluated using software metrics for object-oriented paradigm languages. As a result, there is evidence that developers with different personalities do not develop software of equal quality. As the experiments were run in a single geographic location with an own software development culture, additional studies need to be performed to determine any real link between personality and software quality. / A personalidade dos profissionais de engenharia de software tem sido um elemento contínuo de interesse na pesquisa acadêmica.

Esta dissertação objetiva realizar um estudo para avaliar modelos de personalidade aplicados em engenharia de software e compreender como a personalidade humana influencia a qualidade do software. Dois experimentos controlados foram realizados, o primeiro na indústria, no departamento de TI de uma instituição privada de ensino superior e o segundo em uma disciplina de programação avançada na academia. Para ambas as experiências, a qualidade do software produzido individualmente por cada participante foi avaliada utilizando métricas de software para linguagens de paradigma orientadas a objetos. Como resultado, há evidências de que desenvolvedores com personalidades diferentes não desenvolvem software de qualidade igual. Como os experimentos foram realizados em uma única localização geográfica com uma cultura de desenvolvimento de software própria, estudos adicionais precisam ser realizados para determinar qualquer ligação real entre personalidade e qualidade de software.

Hierdie is 'n psigobiografiese studie van Generaal Christiaan Rudolph de Wet. 'n Psigobiografiese studie is die bestudering van 'n persoon se volledige lewe met die doel om die persoon beter te verstaan. Psigobiografiese navorsing maak gebruik van psigologiese teorieë wat aangewend word om die biografiese data van 'n persoon se lewe te beskryf en moontlik ook te verklaar. Die individu wat bestudeer word, is gewoonlik 'n bekende, invloedryke, navolgenswaardige, interessante of modelfiguur. Daar is tans 'n oplewing in die veld van psigobiografiese studies, maar daar word nog steeds nie genoeg in die akademiese veld gedoen om psigobiografiese studies te bevorder nie. De Wet (1854-1922) is vir hierdie studie gekies omdat hy 'n interessante, dog komplekse figuur was. Hy het veral tydens die Anglo-Boereoorlog in 1899-1902 bekendheid verwerf. As 45-jarige man het De Wet in die Anglo-Boereoorlog geveg en vinnig opgang as 'n militêre leier gemaak. Sy vindingryke ontsnappingspogings het die Britse magte hoofbrekens besorg. Wat De Wet verder uniek maak, is dat hy met net drie maande skoolopleiding in die parlement gedien het, as president verkies is, die hoogste gesag in die Verdedigingsmag gehad het en 'n boek oor sy oorlogsherinneringe geskryf het. Alhoewel daar akademiese werke oor De Wet bestaan, is daar tot op hede nog geen psigobiografiese studie oor hom gedoen nie. Die doel van die studie was om die mens agter die legende na vore te bring. Daar is ook gepoog om moontlike antwoorde en verklarings op onbeantwoorde vrae te gee. Die studie het van beide kwalitatiewe en kwantitatiewe data gebruik gemaak en kan as 'n psigobiografiese gevalstudie beskryf word. Die Vyf-faktor model van Costa en McCrae (1992) is op die biografiese data van De Wet toegepas om sodoende sy persoonlikheidseienskappe te beskryf. Die bevindinge het interessante persoonlikheidseienskappe van De Wet deur middel van die Vyf-faktor model aan die lig gebring. Volgens die kwalitatiewe navorsingsbevindinge was De Wet 'n vyandige, aksie-gedrewe, bevoegde, prestasie-strewende, selfgedissiplineerde, warm, openhartige, saggeaarde en beskeie persoon. Die kwalitatiewe en kwantitatiewe data-ontledings het uiteenlopende persoonlikheidskenmerke by De Wet geïdentifiseer. Die grootste verskille het by die fasette warmte, openhartigheid en altruïsme voorgekom. Die waarde van die studie is dat 'n wetenskaplike persoonlikheidsontleding van De Wet gedoen is. Dit is ook die eerste studie waar 'n teoretiese model op De Wet se persoonlikheid toegepas is. Alhoewel die studie sekere tekortkominge toon, beklemtoon dit terselfdertyd die wenslikheid daarvan om alternatiewe modelle te gebruik tydens die ontleding van persoonlikheidskenmerke. Die studie dui ook op die behoefte aan verdere navorsing, byvoorbeeld soortgelyke ontledings en vergelykings van die persoonlikhede van ander militêre bevelvoerders (De la Rey, Smuts, Beyers, Hertzog).

This study investigated the relationship between conscientiousness, extraversion, and leadership effectiveness among the local government managers in Bisho and East London. Conscientiousness and extraversion were used as independent variables in the study while leadership effectiveness was used as the dependent variable. The data was collected from a sample of 222 local government managers using a self-designed biographical and occupational questionnaire. To measure conscientiousness and extraversion, a 24-item 5-point rating scale adopted from Finchan & Rhodes (2005) was used. To measure leadership effectiveness, a 6-item 5-point derailment rating scale adopted from Lombardo & McCauley (1994) was used. Data analysis was done using various statistical techniques, including t-tests, Pearson Product Moment Correlation Technique and Multiple Regression Analysis. The results indicated that both conscientiousness and extraversion are strongly associated with leadership effectiveness. Conscientiousness was also strongly associated with the individual components of leadership effectiveness, interpersonal relationships; molding a staff; making strategic transitions; follow-through and ability to work independently. Extraversion was also strongly associated with the individual components of leadership effectiveness, molding a staff; making strategic transitions; strategic similarities with management; follow-through and ability to work independently. Although conscientiousness and extraversion combined were found to have an additive effect on leadership effectiveness, conscientiousness accounts for a higher proportion of variance in leadership effectiveness than extraversion. Finally, the results also indicated that age was strongly associated with leadership effectiveness. The study therefore recommends that organisations should use conscientiousness and extraversion when selecting individuals for leadership positions.

Users in social networking sites, such as Facebook, are increasingly receiving friend requests from strangers and accepting strangers as friends. The purpose of this study was to examine the effects of the Big Five personality traits and strangers' gender in affecting Facebook users' decisions to accept the stranger's friend request by adopting a 2 (gender of the stranger: male vs. female) x 5 (stranger's personality: Neuroticism vs. Extraversion vs. Openness vs. Conscientiousness vs. Agreeableness) factorial design. Results revealed that participants were more likely to accept the stranger's friend request when the participant's and stranger's personalities matched. This effect was more pronounced when the stranger was a female. Participants accepted female stranger's friend request due to the inflated perception of stereotypical female characteristics, which supported the hyperpersonal effect. Majority of the participants accepted the stranger's friend request based on textual cues that were displayed in the friend request message, which supported social information processing theory, suggesting that impression formation of the stranger was not constrained to the lack of nonverbal cues setting.

Abstract   Title: The nonprofit leader   Level: Final assignment for Bachelor Degrees in Business Administration   Author: Felicia Jingmyr Steiner and Rebecca Gullersbo   Supervisor: Jonas Kågström   Date: May 2020   Aim: The purpose is to highlight the connection between Big Five´s different personality traits, the dimension according the Maslach Burnout Inventory and the underlying motivational factors within Swedish sport associations and their non-profit leaders.   Method: The study uses a quantitive method with a deductive approach. The method involved a survey in which 380 leaders in Swedish sports associations were assigned the questionnaire. The empirical data was then processed in the analysis and statistics program Jamovi through a descriptive-, correlation- and factor analysis.   Result and analysis: The result of the study showed that leaders with high levels of neuroticism have the biggest risk of burnout. A big part of the study group had high values of conscientiousness and extraversion built in to perform their leadership and involvement tasks well with high efficiency. The result showed that the leaders have a number of underlying motivational factors and not only one. The biggest motivating factor in the leaders who participated in this study was to help other people and the least motivated factor was the monetary reward.   Contribution of the thesis: The study makes the most knowledge and an increased understanding of the interaction between different personality traits with other factors such as burnout and underlying motivational factors. The survey´s selection of leaders within Swedish sport associations provides a practical contribution in the form of knowledge about the leaders themselves and how they should work with them to keep the involvement going.   Suggestions for further research: Upon completion of the study, further research of the sports associations´ leaders and their assignments can a connection between personality traits with other factors such as burnout and underlying motivational factors be found. An interesting angle of this type of research would be relevant is to see how the leader´s actual mission affects its sense of purpose. Further research in sport leaders and their non-profit involvement could do more in-depth by looking at their team/athletes´ demographic variables and strengths to see if the motivational factors are being eradicated because of these.   Keywords: “The Big Five”, “Maslach Burnout Inventory”, burnout, personality trait, volunteer, voluntary work, “Volunteer Function Inventory”, coach, sport

Tato diplomová práce navazuje na bakalářskou práci, ve které byl vytvořen model důvěry pro sociální síť Facebook. Do tohoto modelu jsou zapracovány připomínky z konference UMAP 2013 a ověřena jeho škálovatelnost a flexibilita. V další části práce jsou uvedeny základní termíny z psychologie osobnosti a zkoumána závislost důvěry na osobnosti uživatele. Je vybrán model Big Five k reprezentaci charakteru uživatele a navržen dotazník, u nějž bude zkoumána korelace s modelem důvěry. Tato korelace je na základě sociologických poznatků odhadnuta a později ověřena na reálných uživatelích sociální sítě Facebook.

Recent organisational changes have refocused attention on the productivity and performance of sales representatives and consequently brought about a re-evaluation of the QWL these employees experience, as well as their trust in the organisation to support them. Responses to an internet-based survey methodology were analysed using quantitative techniques and structural equation modelling. Results confirm a positive relationship between Managerial Practices and Organisational Trust, and a lower relationship between the dimensions of Personality and Organisational Trust. A positive relationship was noted between QWL and Managerial Practices, and a lower relationship between QWL and the Personality constructs. This study accentuates the importance of management to be aware of the trust employees have in the organisation as well as their experience of QWL, as it seems as though the Personality traits and Managerial Practices of managers influences both the trust relationship and QWL experienced by employees. / Industrial and Organisational Psychology / M.A. (Industrial and Organisational Psychology)

The new economy is characterised by globalisation, increased competition, and rapid changes. In order to remain competitive, organisations need to be proactive and innovative to survive. This is mirrored in the South African retail industry which is developing into a dynamic industry driven by changes in technology, shifts in consumer behaviour, saturating markets, and increased competition as a result of globalisation. In light of these increased demands on organisations to be more flexible, adaptable, and competitive, new demands have subsequently been placed on leaders. The retail industry is highly labour-intensive and requires effective leadership at all levels, and Transformational Leadership (TL) has been shown to be an effective leadership style to improve various organisational outcomes. In recent years, personality has been used as a means to predict TL behaviours in leaders. One model of personality that has proved its utility in identifying leadership characteristics has been the Five Factor Model of Personality. However, not much is known about the relationship between TL and the Big Five personality factors in the retail industry. The current study utilised a quantitative research approach in which 101 leaders in a retail organisation in South Africa were assessed on TL and the Big Five personality factors, using the Multifactor Leadership Questionnaire and the Fifteen Factor Plus Personality Questionnaire. Correlation analysis was conducted to determine the statistical relationship between TL and the Big Five personality factors. Results indicated that there were no statistically significant relationships between three of the Big Five personality factors, namely extraversion, openness to experience, and conscientiousness, and any of the TL dimensions or the composite TL score. There are two statistically significant relationships between one Big Five personality factor, namely agreeableness, and two TL dimensions, namely inspirational motivation (.196; p < .05), and individualised consideration (.200; p < .05). Only one Big Five personality factor, namely emotional stability, is statistically significantly related to all the TL dimensions as well as the composite TL score, ranging from a low of .539 (p < .01) for idealised behaviour to a high of .556 (p < .01) for the composite TL score. The study concluded that the Big Five personality factors should be used with caution to identify and develop potential TL behaviours in the diverse South African retail context. / Industrial and Organisational Psychology / M.

Orientation In this study the interrelationship between specific personality and interests measures were explored to improve understanding of the respective constructs and their interrelations. A literature study and empirical research was conducted to serve the purpose of this study. Research purpose The purpose of this study was to explore the interrelationship between personality and interests using the measures of the OPQ, the 15FQ+, and the SDS. Motivation for study Much research has been done on the importance of the use of personality and interest questionnaires for career guidance and other purposes. However, a correlation between the SDS and OPQ and between the SDS and 15FQ+ has not been researched. As such, this study was intended to provide valuable insight into the interrelation between the personality and interests as measured by the OPQ, the SDS and the 15FQ+, which should enhance the interpretation of the respective constructs. Research Methodology An exploratory research method was used, as it was a systematic investigation of the relationship among two or more variables. A quantitative strategy of inquiry was used for this study. Main findings A canonical correlation analysis showed moderate to strong interrelationship between personality traits and vocational interest. The interrelation of the OPQ, the SDS and the 15FQ+ are significant. The findings indicated how personality and interests differ and converge for enhancing interpretation purposes. Practical/managerial implications Holland’s theory of vocational interests focuses on the application of the SDS for career purposes, as well as for measuring job fit and job satisfaction. A better understanding of the interrelationship between personality and interests help practitioners to optimize the use of the measures within various contexts. Contributions/value additions The study will enable practitioners to more effectively utilize the personality and interest measures, combined or separately, as the interrelationships are now better known and construct validity is enhanced. Conclusion The objective of this research was successfully achieved, as satisfactory evidence was provided to address the overarching research purpose. / Dissertation (MSc)--University of Pretoria, 2014. / Human Resource Management / MSc / Restricted
