Syftet med studien är att utifrån personlighetsdrag och olika typer av prosocialt beteende identifiera samband mellan vilka som arbetar ideellt och motiven bakom engagemanget. Bakgrunden till intresset grundar sig i en önskan att få en djupare förståelse för indivders ideella engagemang.  Inom den teoretiska referensramen redogörs för ideellt arbete som begrepp samt konceptet i helhet. Här diskuteras de olika punkterna om vad volontärarbete är, vem som volontärarbetar, var volontärarbete finns samt varför människor volontärarbetar. Därefter beskrivs de olika personlighetsdragen samt typer av prosocialt beteende som kommer användas i denna studie. Metoden som valdes var en kvantitativ ansats i form av en enkätstudie och urvalet utgjordes av en kombination av ett bekvämlighetsurval och ett snöbollsurval.  I undersökningen deltog 108 respondenter där frågor om deras ideella arbete besvarades. Tillsammans med detta besvarades ett personlighetstest, Ten Item Personality Inventory, som utvärderade nivåerna av fem personlighetsdrag samt ett test för att mäta nivåer av sex typer av prosocialt beteende, Prosocial Tendency Measure. För att analysera materialet redovisas resultaten i frekvens- och korstabeller.  Resultatet av studien visade att altruism är det främsta motivet till varför individer engagerar sig ideellt. Dock kan detta anses skilja sig mellan olika individer baserat på vad de har för huvudsaklig sysselsättning samt vilket område de engagerar sig inom. Människor som har höga nivåer av personlighetsdragen öppenhet samt tillmötesgående anses mer benägna att engagera sig ideellt. Detta kan till stor del bero på att dessa personlighetsdrag främjar höga altruistiska och ödesdigra prosociala tendenser, vilket medför en önskan att hjälpa andra i olika situationer.

Detta är en studie av artikelplaceringar på logistikföretaget som är placerade pålagerplatser som inte gynnar artiklarnas omsättning. Lagerplatser som är ogynnsamma avA-klassicerande artiklar har påverkat plockfrekvens negativt. Det har bidragit att ledtidenfrån att hämta en A- artikel tar längre tid än att hämta en annan A-artikel med lägreomsättning. Studien identifierar de negativa aspekter som påverkar plockfrekvens och vill bidra medförbättringsförslag för logistikföretaget. Studiens metod skapades genom att samla in datafrån både primär-och sekundärdata. Frågeställning var en del av strukturerad observationoch olika vetenskapliga artiklar relaterade till ämnesområdet samt litteratursökning varen del av primärdata. Studien har resulterat att orsakerna som är ABC-klassificering och Lean har en kopplingtill sambandet mellan artikelplacering och plocktid. Orsakerna som förekommer harbidragit negativ påverkan hos logistikföretaget. Vidare har studien kommit fram till ett resultat genom intervjuer och litteraturteorier därlogistikföretaget förlorar många produktionstimmar kring orsaken. Logistikföretagetbehöver implementera nya åtgärder för förbättring och utveckling. Slutsatsen iundersökningen redovisar vad logistikföretaget ska åtgärda de negativa aspekterna sompåverkar artikelplacering och plocktiden. • Minimera slöseri genom att förkorta gångavståndet. • Omsortera artiklarna. • Kompetensutveckling inom Lean och 5S för att jobba smartare. • Implementera olika standarden som hjälper till att förnya arbetssätt ochutveckling. • Upprätthålla ordning och reda genom att identifiera artiklar som behöverplaceras om och leverantörer. • Utöva mer av parametrar (försäljning, uttag och plockfrekvens). • Effektivisera lagerhanteringssystem (in-och utleveranser, plock, lagerplatser). Arbetet avgränsas till en del av artikeloptimering inom logistik och placering av Aklassificerade artiklar samt påverkan i plockfrekvensen. COVID-19 har varit understudiens tid ett hinder som begränsade studiens författare vistelse hos logistikföretaget. / The purpose of the survey is to investigate article placements at the logistics companythat are unproductively located. Unproductive places of A-classing articles have had anegative effect on picking frequency, which has contributed to the lead time to retrieveone A-article taking longer than retrieving another A-article with lower turnover. The purpose of the survey is to identify the negative aspects that affect the pickingfrequency in order to provide the logistics company with information about the aspectsthat indicate improvement. The method survey was created by collecting data throughboth primary and secondary data. Structured observation and questioning were part of a semi-structured interview andvarious scientific articles related to the subject area as well as literature search were partof secondary data. The investigation has resulted in the current reasons behind theconnection between article placement and picking time having been negatively affectedby the logistics company. Furthermore, research has come to a result where the logistics company loses manyproduction hours around the cause that need to implement new measures for improvementand development. The conclusion of the survey reports that the logistics company shouldaddress the negative aspects that affect item placement and picking time. • Minimize waste by shortening the walking distance. • Rearrange the items. • Skills development within Lean and 5S to work smarter. • Maintain order by identifying items that need to be repositioned and suppliers. • Exercise more parameters (sales, withdrawals and picking frequency). • Streamline inventory managementsystems (inbound and outbound deliveries,picks, warehouse locations). The work was limited to part of article optimization in logistics and placement of Aclassified articles and the impact on the picking frequency. During the study, COVID-19 has been an obstacle that limited the study's authors to stay longer with the logisticscompany.

Master thesis is dealing with the application of particular statistical methods for a description of pharmacy Helios operation. The attention is primarily focused on stock management within the scope of independent demand model, where the related performance indicators of weekly revenues, daily revenues and expenditures per customer are subsequently exposed to thorough analysis. In addition, one of the main goals of this thesis can be identified as the intention to create an application for continuous monitoring of available stock, where their depletion below the specified level would be reported. This thesis should also provide a certain guidelines how the aforementioned application could be integrated within the existing information system in order to automate the process of orders processing.

This diploma thesis deals with the influence of range of reconstruction on the price of building construction. Effect of the extent of reconstruction consists in comparing of the total costs of the bridge during reconstruction of the top of the bridge leaving the main structure and during the reconstruction realized with the exchange of the main supporting structure. The total costs incurred are expected for 60 years.

The aim of thesis is to create the possibility of variant replacement material and to determine the effect of changing bid prices conducted in the building. This price changes investor serves as an important basis for decision making in supplier selection and evaluation of bids when making a tender for the implementation of the building. The practical part is focused on the variability of aggregate in mortars and concretes and compare the resulting prices of newly established budget originally assembled.

Video retrieval represents a challenging problem with many caveats and sub-problems. This thesis focuses on two of these sub-problems, namely shot transition detection and text-based search. In the case of shot detection, many solutions have been proposed over the last decades. Recently, deep learning-based approaches improved the accuracy of shot transition detection using 3D convolutional architectures and artificially created training data, but one hundred percent accuracy is still an unreachable ideal. In this thesis we present a deep network for shot transition detection TransNet V2 that reaches state-of- the-art performance on respected benchmarks. In the second case of text-based search, deep learning models projecting textual query and video frames into a joint space proved to be effective for text-based video retrieval. We investigate these query representation learning models in a setting of known-item search and propose improvements for the text encoding part of the model. 1

The simplicity and ease of use of the Rasch procedure is a decided advantage. The test user needs only two numbers: the frequency of persons who answered each item correctly and the Rasch-calibrated item difficulty, usually a part of an existing item bank. Norms can be computed quickly for any specific group of interest. In addition, once the selected items from the calibrated bank are normed, any test, built from the item bank, is automatically norm-referenced. Thus, it was concluded that the Rasch quick norm procedure is a meaningful alternative to traditional classical true score norming for test users who desire normative data.

Reading competency is related to individuals' success at school and in their careers. Students who experience significant problems with reading may be at risk of long-term academic and social problems. High-quality measures that determine student progress toward curricular goals are needed for early identification and interventions to improve reading abilities and ultimately prevent subsequent failure in reading. The purpose of this quantitative nonexperimental ex post facto research study was to determine whether a correlation existed amongst student achievement scores on the Fountas and Pinnell Reading Benchmark Assessment and reading comprehension scores on the Criterion Reference Competency Test (CRCT). The item response theory served as the conceptual framework for examining whether a relationship exists between Fountas and Pinnell Benchmark Instructional Reading Levels and the reading comprehension scores on the CRCT of students in Grades 3, 4, and 5 in the year 2013-2014. Archival data for 329 students in Grades 3-5 were collected and analyzed through Spearman's rank-order correlation. The results showed positive relationships between the scores. The findings promote positive social change by supporting the use of benchmark assessment data to identify at-risk reading students early.

Orientation: South Africa’s cultural and linguistic diversity requires special measures to ensure that the assessments used in employment settings are scrupulously fair. To this end, Section 8 of The Employment Equity Act requires that psychometric tests are scientifically proved to be valid and reliable and not to discriminate unfairly against any individual or group. The South African Personality Inventory (SAPI) sets out to meet these criteria by incorporating culture-specific elements and by providing versions in each of South Africa’s 11 official languages. o Research purpose: The key determination of this study was to investigate the psychometric properties of the Afrikaans version of the South African Personality Inventory (SAPI). The aforementioned properties include item analysis, exploratory factor analysis (EFA), reliability analysis, product-moment correlation and multivariate analysis of variance (MANOVA). o Motivation for the study: To contribute to the fair, valid and reliable use of the SAPI questionnaire in all language versions of the instrument by examining the psychometric properties of the Afrikaans version and comparing it with the validated English version. Once this has been done for each of the 11 official South African languages versions, a culturally neutral instrument will be available for the full diversity of employment settings in South Africa. o Research design, approach and method: This study used a quantitative cross-sectional research design with an emic approach, objectivist ontology and a post-positivist research paradigm. Primary data was collected by administering the Afrikaans version of the SAPI questionnaire to a non-probability sample of 201 purposively selected white Afrikaans-speaking South Africans who are economically and non-economically active and have a minimum qualification of Grade 12. An online Afrikaans version of the SAPI along with a biographical questionnaire was used to collect data. Item analysis was investigated by means of a descriptive statistical analysis. An initial principle component analysis followed with exploratory factor analysis was performed to determine the instrument’s factor structure. A reliability analysis was conducted in order to measure the internal consistency of the instrument. Product-moment correlations explored the relationships between variables. Further analysis was done to detect the relationships of the variables and to detect differences. Main findings: The White Afrikaners attach immense importance to the social-relational factors. From the six factors, only three factors were extracted, namely the Social-relational Positive, combined Social-relational Negative/Conscientiousness, and Intellect/Openness factors. These factors showed adequate validity and reliability. The item functionality needs to be re-evaluated in order to measure all the six factors of the SAPI and different analytical techniques should be applied. The relationships between the remaining three factors were sufficient, and only age differences were detected in the experience of Social Relational Negative/Conscientiousness o Practical/managerial implications: The results of this study provide a firm foundation for the further investigation of the validity of the Afrikaans version of the questionnaire. Furthermore, insight is given to researchers and practitioners on the need to develop, adapt or translate psychometric instruments, especially for use in an environment which is multicultural and multilingual. o Contribution/value-add: This study contributes to cultural-specific research on the assessment of personality in South Africa. Its thorough investigation and attempt to validate the Afrikaans version of the SAPI is supported by an extensive body of literature relevant to standardizing the SAPI. Practitioners and organisations will now be able to administer a culturally informed personality assessment where the home language of the employees is Afrikaans. / Dissertation (MCom)--University of Pretoria, 2019. / Human Resource Management / MCom / Unrestricted

The purpose of this study was to examine the effects of behavioral checklist critical item content on subsequent global, Likert-type ratings. It was hypothesized that assessment center participants rated with positive critical items would receive higher scores on subsequent global ratings than would participants rated with negative critical items. Additionally, it was hypothesized that volunteers would receive better ratings than nonvolunteers. Finally, it was hypothesized that behavioral ratings would show less susceptibility to halo effect than global ratings.
