Bereavement is painful at any time of life. For young children experiencing bereavement, grandmothers are often the first line of defense. Grandmothers are frequently called upon when their family members experience an out-of-order death, and while they are willing to provide care, grandmothers don't always know the best way forward. This qualitative study sought to learn more about the grief experiences of 22 grandmothers who had lost a family member prematurely through semi-structured interviews and Interpretive Phenomenological Analysis. Findings suggest (a) grandmothers experience layered grief in that they grieve the loss of the family member, experience the pain of the surviving family members, and their own pain; (b) grandmothers experience invisible grief as their feelings are not often revealed to or recognized by their family members; (c) grandmothers experience confusion in knowing how to help and attend to their family members who are bereaved. These difficulties seem related to the family relationships, the connection to the person who died (their own child or an in-law child or grandchild), what they are grieving, and their ability to develop new roles and relationships during the bereavement period.

Syftet med studien var att undersöka förekomsten av arbetsplatsmobbning mot HR-anställda, samt om det fanns några könsrelaterade skillnader gällande tendensen att fallaoffer för arbetsplatsmobbning. Sammanlagt kontaktades 300 organisationer genom ettsystematiskt urval och 58 enkätsvar samlades in. En svensk översättning av verktygetNAQ-R (Rosander & Blomberg, 2018) användes för att identifiera respondenter utsatta förarbetsplatsmobbning. Av de 58 svar som samlades in hade två (3%) respondenter blivitutsatta för arbetsplatsmobbning. Detta var en lägre siffra än vad som tidigare forskningrapporterat inom den svenska arbetsmarknaden. Analys genom användning av MannWhitney U-test visade att det inte fanns några signifikanta könsrelaterade skillnader. Vårslutsats är därför att det inom HR-yrket är ovanligare att falla offer för arbetsplatsmobbningän i det svenska arbetslivet i stort, och att det inte finns några könsrelaterade skillnadergällande tendensen att falla offer för arbetsplatsmobbning inom HR-yrket.

This study explores the phenomenon of computational thinking indicated by the use of Bloom's taxonomy's cognitive domain verbs in the Scratch community, the online, collaborative environment for the Scratch Visual Programming Language (VPL). A corpus of 660,984 words from three Scratch community sub-forums provide the data for this study. By semantically aligning cognitive domain verbs of Bloom's revised taxonomy to computational thinking (CT) dimensions, the occurrences of the verbs in Scratch community sub-forums are used to indicate instances of computational thinking. The methodology utilizes qualitative coding and analysis with R® and RStudio®. The findings show language attributes such as expressions of imagination, sharing of creative details, collaborative development ideas, teaching, modeling, innovating, solutions focused, and technical support to be indicative of computational thinking and CT dimensions. The computational thinking dimension referred to as computational perspectives occurs most frequently within Scratch community participant discourse. The environmental factors found to contribute to computational thinking and the CT dimensions are supporting tools, personalized learning, supportive organizational culture, social learning, and organizational support. Common among the three computational dimensions is the contributing environmental factor described as supportive organizational culture, with the computational perspectives dimension prevailing among the corpora. The characteristics of computational perspectives and supportive organizational culture suggest a desire for human connection in the attainment of technological skills and knowledge.

Clusters e nanoclusters têm recebido grande atenção devido à suas propriedades físicas e químicas, as quais divergem bastante dos materiais na fase bulk. Essas propriedades podem variar de acordo com a composição e tamanho do cluster. Uma compreensão da evolução das propriedades em relação a estes parâmetros é de grande importância para potencializar diversas aplicações, entretanto, esse entendimento permanece insatisfatório. Este trabalho foi dividido em duas etapas, em que a primeira busca investigar parâmetros energéticos, por meio do cálculo da energia de excesso, e estruturais, analisando parâmetro de ordem química, função de distribuição radial central, comprimento médio de ligação e número de coordenação efetiva, dos sistemas ZrnCum-n, ZrnAlm-n, CunAlm-n e ZrnCunAlm-2n para n = 55 e 561 átomos com o incremento n tomado de 1 em 1 para o sistema de 55 átomos e de 20 em 20 para os sistemas de 561 átomos. A segunda etapa consiste de investigar como variam as propriedades energéticas e estruturais do sistema ZrCu em função da evolução do tamanho do sistema. Para alcançar os objetivos propostos, neste trabalho foi usado o algoritmo de otimização global de clusters e nanopartículas basin-hopping Monte Carlo revisado. O potencial de interação atômica utilizado é o método do átomo imerso, que é bastante utilizado na descrição de sistemas metálicos. Os resultados obtidos sugerem que: (i) os sistemas puros apresentaram energia de coesão mais alta que seu análogo material na fase bulk, sugerindo que estes tendem a aglomerar-se formando estruturas bulk. Para os sistemas binários e ternários, foi identificado que todas as composições são energeticamente estáveis devido aos valores negativos obtidos pelo excesso de energia e, para o sistema ZrCu verificou-se a presença de efeitos de tamanho. (ii) Com relação à estrutura, as composições puras estudadas apresentaram simetria icosaédrica. Para o estudo da evolução do tamanho do sistema, Zr e Cu apresentaram estrutura com simetria icosaédrica até a composição de 561 átomos, além deste tamanho a simetria icosaédrica é quebrada. Para os sistemas binários e ternários foi obtido que os átomos tendem a distribuir-se dentro do nanocluster além de apresentarem quebra da simetria icosaédrica apresentando ausência de camadas atômicas ordenadas acompanhada de redução da coordenação efetiva. Os sistemas ZrCu e ZrAl demonstraram seguir a lei de Vegard, enquanto que os sistemas CuAl e ZrCuAl apresentaram desvio da lei de Vegard providos por efeitos eletrônicos, além de apresentarem a presença de efeitos de tamanho. / Clusters and nanocluster have attracted great attention due to their physical and chemical properties, very different from their analogous bulk. These properties can vary with composition and size cluster. An understanding of the properties evolution with respect these parameters is essential to improve several applications. However, this understanding is not complete. This study was piecemeal in two stage, being the first the investigation of energetic properties, by excess energy analisys, and structural properties, by chemical order parameter, radial distribution function, effective coordination number and average bond length, from ZrnCum-n, ZrnAlm-n, CunAlm-n and ZrnCunAlm-2n systems, where n = 55, 561 atoms and the increment n vary in one unit for 55-atoms system and twenty unit for 561-atoms system. The second stage is the investigation of how vary the energetic and structural properties from the size evolution ZrCu system. To do this study, was employed the global optimization algorith for cluster and nanoparticle Revised basin-hopping Monte Carlo, were this method use the classical calculation to determine the total energy of the system. The interatomic potential used was the embedded atom method, that was very usefull to describe metallic systems. Our results suggest: (i) the unary systems present cohesive energy higher than their analogous bulk, that indicate the trend of clusters to form bulk. To the binary and ternary systems, we had that all systems are favorable to form nanoalloys by negative value of excess energy. From ZrCu system, the stability decrease when increase the size of system. With respect the structure, the unary compounds present icosahedral symmetry. From the size-evolution study, the unary compounds present icosahedral symmetry until 561-atoms composition, after this size the icosahedral symmetry is broken. To binary and ternary systems, the atoms trend form mixture into the nanocluster, the icosahedral symmetry is broken with respect the unary compounds and presenting absence of ordered layers followed by effective coordination reduction. The ZrCu and ZrAl systems follow the Vegard law, while the CuAl and ZrCuAl systems present deviation from Vegard law, because electronic effects.

This interview was recently translated into brazilian Portuguese, and it was preliminarily validated for this language. However, this process has been occurred with a small sample in a specific state of Brazil. Besides, other validity evidences, as convergent validity were not explored in this study. Aim: The aim of this study was to investigate the Convergent Validity between the Brazilian version of the ADI-R and a screening tool Autism Behavior Checklist (ABC). Method: For this study, 20 parents or caregivers of children and teens diagnosed with ASD were recruited from the Presbyterian Mackenzie University ASD Clinic, and from the Federal of São Paulo State University Social Cognition Clinic. The children were submitted to a clinical multidisciplinary evaluation, and neuropsychological evaluation that also consisted on application of the ABC. Another researcher, a Child Psychiatrist with expertise on ASD was previously trained and allowed for conducting and codificating the ADI-R. Results: The age of the probands has ranged between 6 and 19 years old, 90% of them were male. The correlations between both the tools, using the Pearson coefficient were mostly positive, and they have ranged between average to high with statistical significance., considering the 3 mains domains of the ADI-R and the five main domains of the ABC. Conclusions: Evidence of convergent validity was found when comparing ADI-R results with ABC/ICA. / Introdução: Os Transtornos do Espectro do Autismo (TEA) são transtornos do desenvolvimento caracterizados por prejuízos qualitativos na interação social recíproca, comunicação e linguagem e pela presença de padrões de comportamentos estereotipados, restritos e repetitivos e sua caracterização se faz a partir de critérios clínicos definidos e padronizados por classificações internacionais como as da CID ou DSM ou por instrumentos, principalmente as entrevistas, como a Autism Diagnostic Interview-Revised (ADI-R), instrumento considerado pela literatura padrão-ouro para diagnóstico de TEA e que recentemente foi traduzido e preliminarmente validado para o português brasileiro. Entretanto, tal processo ocorreu com uma amostra reduzida e numa região específica do Brasil, assim como outras evidências de validade do instrumento tais como validade convergente não foram exploradas. Objetivo: Investigar evidências de validade de convergente entre a versão brasileira da entrevista diagnóstica ADI-R e os instrumento de triagem Inventário de Comportamentos Autísticos (ICA). Método: Foram selecionados 20 pais e/ou cuidadores de 20 sujeitos a partir da Clínica de TEA da Universidade Presbiteriana Mackenzie e da Universidade Federal de São Paulo. Os sujeitos foram submetidos à avaliação clínica multidisciplinar médica e neuropsicológica a qual incluía a aplicação do ICA. Um outro avaliador, psiquiatra da Infância e Adolescência com experiência em TEA e habilitado a aplicar a ADI-R foi responsável pela aplicação e codificação da entrevista. Resultados: A idade dos sujeitos variou de 6 a 19 anos, com média de 10,1. Desses, 90% eram do sexo masculino. Os coeficientes de correlação de Pearson entre os 3 domínios da ADI-R (comunicação, interação social e comportamentos restritos) entre si e destes com o e os do ICA (escrever todos), foram moderados e altos, positivos e a maioria com significância estatística. Conclusões: Evidências de Validade Convergente foram encontradas, comparando-se a ADI-R com o ABC/ICA.

The research focuses on the role of the principal in the implementation of the Revised National Curriculum Statement (RNCS) in Tshwane North District 3. The district is characterised by urban areas, townships and informal settlements. Educators in schools in these areas are well qualified; however, schools in the informal settlement lack resources and facilities. Thus, the curriculum implementation problems experienced by principals and educators in the informal settlements differ from those of principals and educators in urban schools. The amendment of the Curriculum 2005 through the RNCS introduced innovations in schools and changed the principal's role in its implementation. A literature review provided a conceptual framework and covered requirements for successful curriculum implementation, the principal's role therein and relevant training for principals. An empirical investigation using a qualitative approach was conducted and data gathered by interviews with principals, officials from the Department of Education and educators. Finally, a synopsis of the findings and recommendations for further research are provided. / EDUCATIONAL STUDIES / MED (EDUC MANAGEMENT)

Title: LEISURE ASSIGNMENTS -A qualitative textual analysis of leisure-based curriculum Author:  Ljungman Yvonne &  Khelifa Chaht Amina Mentor:  Sahlén Patric Examiner: Lilja Agneta   Term: Spring 2017   In 2016 the leisure had a new chapter in The curriculum for primary school, pre-school class and the leisure (2011). In our study, we examine what the curriculum say about the leisure activities mission. We did our study through a qualitative text analytic method we have designed ourselves. The new curriculum for after-school should supplement the school and give students a meaningful leisure time based on each individual's needs. One mission the leisure have is teaching students, and also educate democratic citizent.  Dewey believed that knowledge is created through experience and actions and it’s consequences. Because the leisure have many missions, the personell in leisure misses interaction and planning time. Interaction and planning time are important factors for the leisure to get a stimulant enviroment.   The research emphasizes that the curriculum for the leisure is a clarification of the leisure mission, but it takes a didactic expertise for those who work at leisure to fulfill the missions. / Titel: FRITIDSHEMMETS UPPDRAG -En kvalitativ textanalys om fritidshemmet med utgångspunkt i läroplanen Författare: Ljungman Yvonne & Khelifa Chaht Amina Handledare: Sahlén Patric Examinator: Lilja Agneta Termin: Våren 2017   År 2016 fick fritidshemmet ett nytt kapitel i Läroplan för grundskolan, förskoleklassen och fritidshemmet (2011). I vår studie undersöker vi vad läroplanen för fritidshemmet säger om fritidsverksamhetens uppdrag. Studien har gjorts genom en kvalitativ textanalytisk metod som vi har konstruerat själva.   Den nya läroplanen för fritidshemmet ska komplettera skolan och ge elever en meningsfull fritid utifrån varje individs behov. Fritidshemmets uppdrag är att undervisa elever. Undervisningen i fritidshemmet har som uppdrag att fostra demokratiska medborgare. Dewey ansåg att kunskap skapas genom erfarenheter och handlingars följder. Fritidshemmets flera uppdrag har gjort att det saknas samverkan och planeringstid för fritidspersonal, som är centrala delar för att fritidsverksamheten ska vara en stimulerad miljö. Forskningen lyfter fram att läroplanen för fritidshemmet är ett förtydligande för fritidsverksamhetens uppdrag, men det krävs en didaktisk kompetens för fritidspersonal att fullfölja uppdragen.

Many educational systems of today are standards-based and aim at for alignment, i.e. consistency, among the components of the educational system: standards, teaching and assessment. To conclude whether the alignment is sufficiently high, analyses with a useful model are needed. This thesis investigates the usefulness of models for analyzing alignment between standards and assessments, with emphasis on one method: Bloom’s revised taxonomy. The thesis comprises an introduction and five articles that empirically investigate the usefulness of methods for alignment analyses. In the first article, the usefulness of different models for analyzing alignment between standards and assessment is theoretically and empirically compared based on a number of criteria. The results show that Bloom’s revised taxonomy is the most useful model. The second article investigates the usefulness of Bloom’s revised taxonomy for interpretation of standards in mathematics with two differently composed panels of judges. One panel consisted of teachers and the other panel of assessment experts. The results show that Bloom’s revised taxonomy is useful for interpretation of standards, but that many standards are multi-categorized (placed in more than one category). The results also show higher levels of intra- and inter-judge consistency for assessment experts than for teachers. The third article further investigates the usefulness of Bloom’s revised taxonomy for analyses of alignment between standards and assessment. The results show that Bloom’s revised taxonomy is useful for analyses of both standards and assessments. The fourth article studies whether vague and general standards can explain the large proportion of multi-categorized standards in mathematics. The strategy was to divide a set of standards into smaller substandards and then compare the usefulness and inter-judge consistency for categorization with Bloom’s revised taxonomy for undivided and divided standards. The results show that vague and general standards do not explain the large proportion of multi-categorized standards. Another explanation is related to the nature of mathematics that often intertwines conceptual and procedural knowledge. This was also studied in the article and the results indicate that this is a probable explanation. The fifth article focuses on another aspect of alignment between standards and assessment, namely the alignment between performance standards and cut-scores for a specific assessment. The validity of two standard-setting methods, the Angoff method and the borderline-group method, was investigated. The results show that both methods derived reasonable and trustworthy cut-scores, but also that there are potential problems with these methods. In the introductory part of the thesis, the empirical studies are summarized, contextualized and discussed. The discussion relates alignment to validity issues for assessments and relates the obtained empirical results to theoretical assumptions and applied implications. One conclusion of the thesis is that Bloom’s revised taxonomy is useful for analyses of alignment between standards and assessments. Another conclusion is that the two standard setting methods derive reasonable and trustworthy results. It is preferable if an alignment model can be used both for alignment analyses and in ongoing practice for increasing alignment. Bloom’s revised taxonomy has the potential for being such an alignment model. This thesis has found this taxonomy useful for alignment analyses, but its’ usefulness for increasing alignment in ongoing practice has to be investigated.
