Inledningsvis utfördes en problematisering kring ämnet organisationsförändringar för att få en djupare kunskap. Problemet kring det studerade ämnet grundar sig i att förändringar idag är en viktig och fundamental del för organisationer att genomgå för att kunna verka effektivt och anpassningsbart på den dynamiska marknad som organisationer idag är verksamma på. En organisationsförändring har ofta goda ambitioner och intentioner inledningsvis men trots detta misslyckas 70 procent av alla förändringsinitiativ. För att studera denna problematik har syftet med studien varit att undersöka om det går att urskilja om en formellt utsatt organisationsförändring uppnått sitt initiala förändringssyfte utsatt av ledningen. Vidare ämnar uppsatsen undersöka hur medarbetare, utifrån ett öppet och tolkande perspektiv uppfattat och hanterat organisationsförändringen. Problematiseringen grundar sig i en nyligen genomförd organisationsförändring i form av en sammanslagning mellan två lokala bankkontor till en samlad enhet på en svensk storbank. Undersökningen har utförts med en kvalitativ ansats i form av djupintervjuer med tio respondenter på de lokala bankkontoren. Teorin består utav tidigarelagd forskning i form av vetenskapliga artiklar med huvudområdena ledarskap, kommunikation och förändringsmotstånd kopplat till organisationsförändringar. Empirin har samlats in på de lokala bankkontoren som är berörda av sammanslagningen med ett intervjuunderlag via en öppen ansats i syfte att fånga medarbetares upplevelse och uppfattningar kring den omorganisering som ägt rum. Övergripande mönster som framkommit i analysen är främst bristfällig kommunikation och ett bristfälligt förändringssyfte samt även positiva aspekter sett till ledarens roll som stöttande och positiv i förändringsprocessen. Utfallen är inte helt homogena, och i flera avseenden spretar svarsutfallen, men nyss nämnda mönster återspeglas av betydande majoritet av organisationsanhängarna. Det finns mycket som pekar på att flertalet av medarbetarna upplever att syftet kring förändringen varit bristfälligt från förändringsledaren sida och att detta kan ha bidragit till ett ifrågasättande kring varför förändringen genomförs samt vad den skall föra med sig för positiva aspekter i slutändan. / Initially, problematization was carried out on the topic of organizational change in order to gain deeper knowledge. The problem of the subject studied is that changes today are an important and fundamental part of organizations to undergo in order to function effectively and adaptably in the dynamic market in which organizations today are active. An organizational change often has good ambitions and intentions initially, but despite this, 70 percent of all change initiatives fail. To study this problem, the purpose of the study has been to investigate whether it is possible to find out if a formally adopted organizational change has achieved its initial purpose detemrined by management. Furthermore, the paper aims at investigating how employees, from an open and interpretative perspective, perceived and managed the organizational change. The problematization is based on a recent organizational change in the form of a merger between two local bank branches into a single entity on a Swedish bank. The survey has been conducted with a qualitative approach in the form of focus interviews with ten respondents at the local bank offices. The theory consists of earlier research in the form of scientific articles with the main areas of leadership, communication and change resistance associated with organizational changes. Empirical data has been collected at the local banking offices who were affected by the merger through an interview paper, through an open mind to capture employee experiences and perceptions about the reorganization that took place. Overall patterns identified in the analysis are mainly inadequate communication and a lack of purpose to change, as well as positive aspects seen as the leader's role as supportive and positive throughout the change process. The outcome is not entirely homogeneous, and in several respects the answers differs throughout the research, but the pattern mentioned above is reflected by a significant majority of the organizational followers. There are many indications that most of the employees find that the purpose of the change has been inadequate while communicated from the change leader and that this may have contributed to an issue of why the change is being implemented and what positive aspects it should eventually have resulted in.

The failure rate in mathematics at school is high, not only in South Africa, but also internationally. Furthermore, learners with an apparently high general ability or aptitude for mathematics sometimes underachieve in the subject, while some learners with an apparently low general intellectual ability or aptitude for mathematics sometimes achieve well in the subject. Little attention is nonetheless given to learners' study orientation in mathematics, in spite of the fact that research has indicated that school mathematics is one of the best predictors of success in tertiary studies. An investigation into some epistemological approaches to the learning process in mathematics confirms that learners' achievement in mathematics is significantly affected by their study orientation in mathematics. The primary aim of this thesis was the development and evaluation of a study orientation questionnaire (SOM) in mathematics. Data processing procedures especially referred to the following two primary aims with the study: (a) Standardisation of the questionnaire. Steps carried out to evaluate the questionnaire psychometrically, include factor and item analysis. In the case of Grade 8 and 9, three fields (Study habits in mathematics, Mathematics anxiety and Study attitudes in mathematics) were identified. A fourth field, Locus of control regarding mathematics, was identified only in the case of learners in Grade 1 0 and ll. It was established that the SOM apparently has criterion related validity, as well as content and construct validity for the three language groups as a whole. Reliability coefficients for the SOM can in most cases be regarded as satisfactory. (b) Comparative studies to determine the applicability of the SOM. Analysis of variance techniques were used to determine where significant differences between groups (including grade-, mother tongue and sex groups) lay. Where MANOV AS showed significant differences, further investigation was carried out to determine in respect of which individual fields (single variables) groups differed significantly. By means of LSM it was determined which groups differed significantly in regard of the separate fields. Some of the findings include: * It seems that African language speakers in both grade groups are really trying to achieve in mathematics, but that their best efforts are not successful. * It would appear that girfs' level of Mathematics anxiety drops in Grade l 0 and ll. * Learners in Grade l 0 and ll show lower levels of Mathematics anxiety and more sufficient Study habits in mathematics than their counterparts in Grade 8 and9. * Perhaps the most significant finding is the phenomenon that African language learners in Grade l 0 and l l achieved much worse in regard of Locus of control than Afrikaans and English-speaking learners. A number of factors probably contribute towards this state of affairs, including language problems, teachers who are underqualified, African language learners' less than optimal socioeconomic status (SES) in general, a lack of facilities and text books and disruption which is still being experienced in rnnny traditionally black schools. It is recommended that these matters ·are attended to in an effort to create circumstances for more sufficient achievement in mathematics by learners from all language groups. / Thesis (PhD)--University of Pretoria, 1997. / Human Sciences Research Council (South Africa) / Psychology / PhD / Unrestricted

Cette thèse contient trois essais sur la coopération, mesurée à travers les contributions dans le jeu du bien public.Dans le premier chapitre, je propose une revue de la littérature sur l’hétérogénéité dans les jeux de bienpublic linéaires. Je distingue deux types d’hétérogénéité : l’hétérogénéité en dotation et l’hétérogénéité en rendement du bien public (c’est-à-dire en MPCR). Malgré un conflit normatif exacerbé, les agents hétérogènes contribuent autant au bien public que des agents homogènes. Sont-ils en mesure d’utiliser des mécanismes pour atteindre l’efficience (une provision complète du bien public) ? Mes résultats sont nuancés. Les agents hétérogènes en dotation sont capables de "s’autogouverner" et d’atteindre l’efficiencetandis que les agents hétérogènes en MPCR ne parviennent pas parfaitement à surmonter le problème de la sous-provision du bien public.Dans le deuxième chapitre, co-écrit avec Adam Zylbersztejn, nous étudions les effets d’un risque environnemental sur la coopération. Nous appelons risque environnemental une situation dans laquelle le rendement du bien public est risqué au moment de la décision. Nous considérons, dans notre expérience, deux types de risque : un risque individuel (le MPCR est déterminé indépendamment pour chaque membre du groupe) et un risque collectif (le MPCR est le même pour chaque membre du groupe). Nous constatons que le risque n’affecte pas la coopération : les sujets ne contribuent pas différemment au bien public lorsque le MPCR est certain ou lorsqu’il est risqué.Dans le troisième chapitre, j’examine les effets d’un mécanisme fondé sur la compétition intragroupe pour financer des biens publics. Dans mon expérience, les agents sont en compétition pour obtenir un MPCR plus élevé. Le rang dans la compétition - et donc le MPCR - dépend de la façon dont la contribution d’une personne se classe au sein de son groupe. Je trouve que la compétition n’améliore la provision des biens publics que lorsqu’elle ne génère pas d’inégalités trop importantes. / This thesis contains three essays on cooperation, observed through the contributions in the Public Good Game. In the first chapter, I survey the literature on heterogeneity in linear Public Good Games. I distinguish two kinds of heterogeneity: heterogeneity in endowment and heterogeneity in return from the public good (i.e. MPCR). Despite a normative conflict exacerbated, heterogeneous agents contribute as much as homogeneous agents to the public good. Are they able to use mechanisms to reach efficiency (i.e. a full provision of the public good)? I find mixed evidence. Agents heterogeneous in endowment are able to govern themselves and to reach efficiency while agents heterogeneous in MPCR do not perfectly overcome the underprovision problem.In the second chapter, co-written with Adam Zylbersztejn, we investigate the effects of environmental risk on cooperation. We call an environmental risk a situation in which the return of the public good is risky at the time of the decision. We consider, in our experiment, two kinds of risk: an individual one (i.e. the MPCR is determined independently for each group member) and a collective one (i.e. the MPCR is the same for each group member). We find that risk does not affect cooperation: subjects do not contribute to the public good differently when the MPCR is certain or when it is risky.In the third chapter, I investigate the effects of a mechanism based on within-group competition to provide public goods. In my experimental treatments, agents compete for a higher MPCR from the public good. The rank in the competition - and therefore the MPCR - depends on how one’s contribution ranks within the group. I find that competition improves public goods provision only when it does not generate too large inequalities.

Introduction: The field of SLP continues to expand, posing challenges to academic and clinical preparation of SLPs (Roth, 2015; Mason et al., 2020). According to Carozza (2019), this rapid growth has led to an increase in the roles and responsibilities for SLPs, including managerial and leadership roles. Leadership in healthcare professions is a developing field and has gained new importance with the global COVID-19 pandemic. According to ASHA’s Professional Issues Statement on the roles and responsibilities of Speech-Language Pathologists in schools (ASHA Practice Policy, 2019), leadership is an important core role and responsibility. This leadership role is performed in advocacy, supervision and mentorship, professional development, parent training and research (ASHA, 2016). Current literature reveals an emphasis on leadership in both Interprofessional Education (IPE) and Interprofessional Practice (IPP). This development emphasizes the importance of exploring leadership in school-based SLPs. Secord (2007) stated that SLPs who are in a leadership capacity can profoundly influence school-based practice. Aim: The purpose of this study is to explore leadership from the perspective of school-based SLPs through survey research. Methods: An exploratory, descriptive, quantitative research design was selected to explore the personal perspectives of school-based SLPs regarding their training in, perceptions of, and experiences regarding leadership. An online survey was developed to answer the following research questions: (1) What leadership training have school-based SLPs been exposed to? (2) What leadership positions do school-based SLPs hold? (3) What leadership characteristics do school-based SLPs consider to be essential for leadership in schools? (4) Which specific needs do school-based SLPs have relating to their leadership roles and goals? A total of 112 practicing school-based clinicians acted as respondents. Descriptive and inferential statistics were used to analyze the data. Thematic analysis was done on the results obtained from the open-ended question. Summary: 92% of the respondents reported that they did not receive any form of leadership education in their graduate program. Only 7% responded that they felt prepared for a leadership position upon graduation. 54% of school-based SLPs reported that they currently hold a leadership position within their school. Some of the leadership characteristics, skills, and strategies identified to be the most important include building trusting relationships; strong collaboration skills; being a good communicator; demonstrating inclusivity; prioritizing students; communicating regularly with teachers; and implementing evidence-based practice. Additionally, the important leadership characteristics to implement during a crisis such as the COVID-19 pandemic were identified as effective and clear communication, flexibility, and the ability to provide clear directions to initiate and maintain action. 59% of the respondents indicated that they would be interested in receiving further information on developing leadership skills in the schools, the most popular preferences being continuing education courses, in-service training, and ASHA annual conventions. The findings indicate an urgent need for increased leadership training in SLP graduate institutions, which may serve to increase both the numbers of school-based SLPs who hold a leadership position, as well as the quality of leadership that school-based SLPs provide within their positions.

Nonmedical prescription drug (NMPD) use is a well-documented problem among college students, but few studies have examined nursing students' attitudes regarding NMPD. The purpose of this study was to compare nursing and non-nursing students' attitudes, risk factors, and current substance use. This descriptive, comparative design utilized a convenience sampling and social media to reach students over 18 years of age and enrolled in a Midwestern university. Twenty-nine students, 14 non-nursing and 15 nursing students, participated in this online survey. Substance use attitudes were measured using the Drug Attitude Scale (DAS). Risk factors for substance use were used as demographic questions and current drug use was measured using the Drug Abuse Screening Tool (DAST). Logistic regression (Chi-Square/Fisher's Exact) analyses were used to observe the association between risk factors for substance abuse and nursing/non-nursing students. Additionally, a Simple Linear Regression (Two-Sample T-tests) was used to assess the relationship between DAS and DAST scores between nursing/non-nursing students. Prior to discussing the results of the statistical tests, descriptive statistics of the demographic variables of the participants are presented. Data analysis revealed no significant difference in attitude, risk factors, and substance use among nursing students and non-nursing students. Limitations included the low number of participants and access to students via social media only. The fact that nursing students receive additional training in pharmacology, we presume these students know the risks of drug use, therefore nursing students would have a lower rate of substance use; however, this study revealed no significant difference in attitudes or current substance use among nursing and non-nursing students.

Yes / The upper reach of the Yellow River from Daliushu to Shapotou consists of five bends and has complex topography. A two-dimensional Re-Normalisation Group (RNG) k-ε model was developed to simulate the flow in the reach. In order to take the circulation currents in the bends into account, the momentum equations were improved by adding an additional source term. Comparison of the numerical simulation with field measurements indicates that the improved two-dimensional depth-averaged RNG k-ε model can improve the accuracy of the numerical simulation. A rapid adaptive algorithm was constructed, which can automatically adjust Manning's roughness coefficient in different parts of the study river reach. As a result, not only can the trial computation time be significantly shortened, but the accuracy of the numerical simulation can also be greatly improved. Comparison of the simulated and measured water surface slopes for four typical cases shows that the longitudinal and transverse slopes of the water surface increase with the average velocity upstream. In addition, comparison was made between the positions of the talweg and the main streamline, which coincide for most of the study river reach. However, deviations between the positions of the talweg and the main streamline were found at the junction of two bends, at the position where the river width suddenly decreases or increases. / National Natural Science Foundation of China (Grants No. 11361002 and 91230111), the Natural Science Foundation of Ningxia, China (Grant No. NZ13086), the Project of Beifang University of Nationalities, China (Grant No. 2012XZK05), the Foreign Expert Project of Beifang University of Nationalities, China, and the Visiting Scholar Foundation of State Key Laboratory of Water Resources and Hydropower Engineering Science, Wuhan University, China (Grant No. 2013A011).

Doctor of Philosophy / Department of Curriculum and Instruction / M. Gail Shroyer / This study was designed to examine one component of impact within a High School Professional Development School (PDS) partnership. The purpose of this study was to explore the perceived impact of pre-service teachers on the students they teach and the cooperating teachers who mentor them. More specifically, this study was designed to explore the impact on the learning environment of high school students who were taught by pre-service teachers and the cooperating teachers who mentored them from the perspective of 8 pre-service teachers, 130 high school students, and 8 cooperating teachers. The theoretical framework for this study was based on the concept of an Optimal Learning Environment (National Research Council, 1999). The overarching question for this study was: In what ways do pre-service teachers impact the learning environment of the PDS in which they complete their final clinical experience? Survey and interview data were gathered from participants to explore the perceived impact of the pre-service teachers on the (a) learner centered learning environment, (b) assessment centered learning environment, and (c) knowledge centered learning environment of the high school students and cooperating mentor teachers. The data collected were focused on what the high school students, pre-service teachers and cooperating mentor teachers perceived based on their personal experiences and understanding. The results of this study indicated a perceived positive impact on the learner centered, assessment centered, and knowledge centered learning environments of the high school students and the cooperating mentor teachers from the perspectives of the high school students, pre-service teachers and cooperating mentor teachers. The researcher thus concluded that the pre-service teachers positively impacted the perceived Optimal Learning Environment of the PDS in which they completed their final clinical experience.

Daar heers tans 'n verwarring in baie mense se gemoedere, teoloe sowel as ander gelowiges, aangaande die heilsweg. Aan die een kant is daar die mense wat glo dat jy jou moet bekeer om in die verlossing te kan deel (die bekeringsteologie) . Aan die ander kant is daar diegene wat glo dat die mens klaar gered is, en enige poging, hetsy deur geloof of bekering, van mensekant is sinergisme (verbondsteologie) . In ons soeke na 'n oplossing het ons na die verbond as moontlike vertrekpunt gaan kyk, en gevind dat die verbond inderdaad 'n oplossing bied. Die verbond het verskeie prinsipiele eienskappe, en die kern daarvan is dat dit 'n Godgegewe instelling is met duidelike inhoude. Onder andere het die verbond 'n monopleuriese instelling, maar ook 'n dupleuriese werking. Hieruit volg dat die verbond op die verantwoordelikheid van die mens appeleer. Die appel van die verbond kom tot uiting in die oproep om die verlossingsdade van Christus aan te gryp. Vervolgens is gekyk na die manier waardeur 'n mens sy verantwoordelikheid nakom. In sowel die Ou as Nuwe Testament is dit duidelik dat die mens wat nie in 'n verbondsverhouding met die Here leef nie, gevaar loop om uit die verbond gesny te word. Die enigste manier om verseker dat 'n mens in die verbondsbelof tes de el, is deur bekering. Die Bybel maak nie 'n duidelike onderskeid tussen eerste en voortgaande bekering binne die verbond nie. God gee die bekering, maar vereis dit ook / There is presently a great deal of confusion in the minds of people, theologians as well as lay members, regarding the way of salvation. On the one hand there are those who believe that one must be converted before one can share in salvation. It may be called a theology of conversion. On the other hand there are those who believe that the people of the covenant are already saved, and all endevours to claim the salvation by faith or repentance, are forms of synergism. In our attempt to find a solution, we have taken the covenant as pain of departure. The covenant has many qualities, but the central aspect is the fact that the covenant is a God-given entity and therefore has certain specific characteristics like a monopleuric origin (in God} but a dupleuric working (divine and human responsibility) . According to the Old Testament as well as the New Testament, it is clear that those covenant people who do not commit themselves to the God of the covenant, and accept its demands, are in danger of being cut off from the covenant. The only way to restore the covenant relationship is by repentance and conversion. Concerning the covenant the Bible does not make any clear difference between a radical initial conversion and an ongoing one. God gives conversion, but also demands it / Philosophy, Practical & Systematic Theology / D. Th. (Sistematiese Teologie)

Climate policy has been mainly studied with economic models that assume representative, rational agents. However, it aims at changing behavior associated with carbon-intensive goods that are often subject to bounded rationality and social preferences, such as status and imitation. Here we use a macroeconomic multi-agent model with such features to test the effect of various policies on both environmental and economic performance. The model is particularly suitable to address distributional impacts of climate policies, not only because populations of many agents are included, but also as these are composed of different classes of households driven by specific motivations. We simulate various policy scenarios, combining in different ways a carbon tax, a reduction of labor taxes, subsidies for green innovation, a price subsidy to consumers for less carbon-intensive products, and green government procurement. The results show pronounced differences with those obtained by rational-agent model studies. It turns out that demand-oriented subsidies lead to lower unemployment and higher output, but perform less well in terms of carbon emissions. The supply-oriented subsidy for green innovation results in a significant reduction of carbon emissions with a slight reduction of unemployment. / Series: WWWforEurope

La présente thèse s'intéresse à l'évolution d'organisations à caractère démocratique ou ouvert, au travers de leur stabilité ainsi que d'autres caractéristiques comme leur capacité à fédérer, à satisfaire leurs membres ou pérenniser des situations de partage de risque entre agents hétérogènes. Les modèles proposés sont des modèles agents qui s'appuient sur une étude menée depuis 2004 par Juliette Rouchier sur les circuits courts agroalimentaires et particulièrement sur les Associations pour le Maintien d'une Agriculture Paysanne (AMAP) et leur structuration en réseaux d'AMAP à différentes échelles géographiques. La thèse suggère l'existence d'une tension entre la stabilité et la représentativité dans ce type d'organisations démocratiques et discute, dans plusieurs cas de figure, l'impact de différents facteurs sur cette tension comme le nombre de sujets discutés dans l'organisation, l'état d'esprit des membres, l'existence d'une communication structurée au sein de l'organisation, ou encore la répartition géographique des membres. Dans un second temps la thèse s'intéresse à des groupes de partage de risque entre agents hétérogènes, comme c'est le cas dans les AMAP entre producteurs et consommateurs. Elle suggère que l'apprentissage par les agents de leurs risques, c'est à dire de leurs préférences vis-à-vis des caractéristiques de leur organisation au cours du temps, pérennise un partage de risque complet entre des agents hétérogènes. De plus cet effet semble renforcé par l'introduction de préférences pour autrui, comme l'altruisme ou l'aversion aux inégalités. / This PhD thesis studies the evolution of organizations under democratic settings through their stability along with other characteristics like their representativeness, their capacity to satisfy their members or to ensure risk sharing agreement between heterogenous agents. Proposed models are agent based models grounded in a study, initiated by Juliette Rouchier in 2004, on short food chains and particularly on "Associations pour le Maintien d'une Agriculture Paysanne" (AMAP), the french equivalent of United States' Community Supported Agriculture (CSA) along with their structuration in AMAP' networks at different geographical levels. This PhD thesis suggests the existence of a tension between stability and representativeness under democratic settings and discusses, in different cases, the effect of several factors on this tension, like the number of topics discussed in the organization, the state of mind of members, the existence of structured communication, or the spatial repartition of members. In a second part, this Phd thesis deals with risk sharing groups between agents heterogenous in terms of risk exposures, as it is the case in AMAP between producers and consumers. It underlines how learning by agents of their risk exposures through times, which is equivalent here to constantly revise their preferences with respect to the characteristics of their organization, can stabilize risk-sharing groups mixing heterogenous agents and how this effect is strengthen by the introduction of other-regarding-preferences, like altruism or inequality aversion.
