Learners with Attention Deficit Hyperactivity Disorder (ADHD) traditionally display disruptive and other associated negative behaviour in the classroom setting. Behaviour management strategies utilised by the teacher in the school environment can assist in reducing this type of behaviour that impacts negatively upon their academic performance. This research study develops and investigates the effectiveness of a programme of practical behaviour management strategies designed to reduce disruptive behaviour of learners with ADHD in the classroom. / Educational Studies / M.

The Pompidou Center is a State-funded presidential museum project, with the mission to make modern art in all its expressions accessible to the wider public. The Sesc Pompeia is a multidisciplinary center for culture and sports financed by tax-money and managed by the Commerce Federation. The Sesc Pompeia is dedicated to the provision of informal education through the cultivation of the mind and the body. The study examines whether resource- and power-dependence theories can be used to conceptualize the relationship that the Pompidou Center & the Sesc Pompeia have with their financial stakeholders. More specifically it will be discussed to what extent the degree of power-dependence in the relationship influences the management strategy of the institution. The objective is to answer the question: what strategies do the institutions adopt to reduce their power-dependence on their main financial stakeholders? Finally some practical management implications will be drawn from the parallel between the strategies of the two institutions. / A presente pesquisa foi conduzida na forma de um estudo de caso de duas instituições culturais no contexto francês e brasileiro. O Centro Pompidou é um projeto presidencial de museu financiado pelo Estado, com a missão de tornar a arte moderna em todas as suas expressões acessíveis ao público em geral. O Sesc Pompeia é um centro multidisciplinar de cultura e esporte - financiado pelo dinheiro dos impostos e administrado pela Federação do Comércio. O Sesc Pompéia é dedicado à oferta de educação informal através do cultivo da mente e do corpo. O estudo examina se as teorias de dependência de recursos e de poder podem ser utilizadas para conceituar a relação que o Centro Pompidou e do Sesc Pompéia tem com seus stakeholders financeiros. Mais especificamente, será discutido em que medida o grau de dependência influencia a estratégia de gestão das instituições. O objetivo é de responder a pergunta seguinte: quais são as estratégias que as instituições adotam para reduzir sua dependência com relação a seus principais stakeholders financeiros? Finalmente algumas implicações práticas de gestão serão elaboradas a partir do paralelo entre as estratégias das duas instituições.

The issue of rapid change in environmental conditions under which ecosystem processes and human interventions will take place in the future is relatively new to forestry, whereas the provision of ecosystem services, e.g., timber or fresh water, is at the very heart of the original concept of forest management. Forest managers have developed ambitious deterministic approaches to provide the services demanded, and thus the use of deterministic approaches for adapting to climate change seem to be a logical continuation. However, as uncertainty about the intensity of climate change is high, forest managers need to answer this uncertainty conceptually. One may envision an indeterministic approach to cope with this uncertainty; but how the services will be provided in such a concept remains unclear. This article aims to explore the fundamental aspects of both deterministic and indeterministic approaches used in forestry to cope with climate change, and thereby point out trade-offs in service provisioning and adaptability. A forest owner needs to be able to anticipate these trade-offs in order to make decisions towards sustainable forest management under climate change.

El objetivo principal de la investigación fue determinar la relación que existe entre las estrategias de gestión de retención del talento humano y la rotación de personal en el sector textil 2019, bajo una metodología de diseño no experimental, de corte transeccional correlacional, explorando los hechos directamente de los colaboradores mediante la recolección de los datos en un solo momento. Para ello se encuestaron 261 trabajadores de 9 empresas Top de Lima Centro, como muestra de estudio, y quienes se les aplico los instrumentos de estudio, cuyo valor de Alfa de Cronbach muestra una elevada (0.968), y aceptable confiabilidad (0.871). En los resultados se determinó un coeficiente de correlación inverso entre las variables, mediante la prueba de Rho de Spearman (rho= -0633) y un p valor = 0.000 menor al nivel de significancia establecido (p valor < 0.05), que conllevo al rechazo de la hipótesis nula y la aceptación de las hipótesis planteadas, concluyendo que: “Existe una relación significativa entre las estrategias de gestión de retención del talento humano y la rotación de personal en el sector textil 2019”. Así mismo, se determinó que la gestión estratégica aplicada por las empresas textiles para retener el recurso humano, es catalogada por el 48% de colaboradores en niveles moderados y por el 41% en niveles altos, mientras que la rotación de personal fue caracterizada por el 61% en niveles moderados y por el 30% en niveles bajos. / The main objective of the research was to determine the relationship that exists between the management strategies for the retention of human talent and the turnover of personnel in the textile sector 2019, under a non-experimental design methodology, of a transactional correlational cut, exploring the facts directly of collaborators by collecting data in a single moment. For this, 261 workers from 9 Top companies in Lima Centro were surveyed, as a study sample, and who were applied the study instruments, whose Cronbach's Alpha value shows a high (0.968), and acceptable reliability (0.871). In the results, an inverse correlation coefficient was determined between the variables, using Spearman's Rho test (rho = -0633) and a p value = 0.000 lower than the established level of significance (p value <0.05), which led to rejection. Of the null hypothesis and the acceptance of the hypotheses, concluding that: "There is a significant relationship between the management strategies for the retention of human talent and the turnover of personnel in the textile sector 2019". Likewise, it was determined that the strategic management applied by textile companies to retain human resources is classified by 48% of collaborators at moderate levels and by 41% at high levels, while staff turnover was characterized by the 61% at moderate levels and 30% at low levels. / Tesis

Management of teachers is one of the important tasks of principals at school, aside from their primary goal of ensuring that teaching and learning happens effectively at school, is their potential to manage two types of teachers present at school, unionised and non-unionised. It is well-established that principals have a mammoth task of identifying and implementing the correct strategies to manage these teachers. A review of the management styles in use today shows that the new management strategies are required to solve the problems encountered by principals in managing these teachers. Several methods of implementing these new strategies are described. These methods include creating trust between teachers and principals through fruitful communication and participation in decision-making. The application of the theory of emotional intelligence is described in detail. The theory of emotional intelligence denotes that the accomplishment in the management of human resources depends largely on the emotions, behaviours, and attitudes of managers. While past studies have detailed the effectiveness of the management styles used by principals to manage teachers, these studies have been confined to the management of teachers collectively. The present study distinguishes between teachers who are unionised and non-unionised and the individual, focus group interview and observation are the primary sources of data used in the study. The findings are intended to solve challenges associated with the implementation of the management strategies of principals in managing unionised and no-unionised teachers to attain improved quality teaching and learning in the context of South African secondary schools. The results show that developing trust between principals and teachers requires efforts from both parties. They also show that the main complaint about the management of teachers is unequal treatment of teachers and a lack of trust between teachers and principals in schools. The analysis of individual interviews, focus-group interviews and observations revealed that the establishment of strategies that address both types of teachers found at schools would be a significant step to take towards a positive management of teachers. It is proposed that the Department of Basic Education creates an environment where both teachers and managers’ personal and professional development is upskilled to expand their capabilities to deal with relational problems and challenges. / Educational Management and Leadership / Ph.

<p>Bed bugs (<i>Cimex lectularius</i> L.) are globally important human ectoparasites. Their management necessitates the use of multiple control techniques. Plant-derived essential oils are extracts from aromatic plants that represent one of the alternative control measures for bed bug control, in addition to mechanical options and synthetic pesticides. However, there is limited information available on the efficacy and toxicology of plant essential oils against bed bugs. This project was designed with the aim to provide in-depth information on efficacy, toxicology and mode-of-action of essential oils and their insecticidal constituents in bed bugs. Initially, I evaluated topical and fumigant toxicity of fifteen essential oil components against adult male bed bugs of the Harlan strain (an insecticide susceptible strain). Neurological effects of the six most toxicologically active compounds were also determined. In both topical and fumigant bioassays, carvacrol and thymol were the most active compounds. Spontaneous electrical activity measurements of the bed bug nervous system demonstrated neuroinhibitory effects of carvacrol, thymol and eugenol, whereas linalool and bifenthrin (a pyrethroid class insecticide) produced excitatory effects. Further, I evaluated the efficacy and neurological impacts of a mixture of three neuroinhibitory compounds; carvacrol, eugenol and thymol in 1:1:1 ratio against adult male bed bugs of the Harlan strain. This mixture of monoterpenoids as well as the mixture of synthetic insecticides exhibited a synergistic affect in topical bioassays. In electrophysiology experiments, the monoterpenoid mixture led to higher neuroinhibitory effects, whereas a mixture of synthetic insecticides caused higher neuroexcitatory effects in comparison to single compounds. </p> <p>In the next objective of my dissertation, I compared the efficacy of five plant essential oils (thyme, oregano, clove, geranium and coriander), their major components (thymol, carvacrol, eugenol, geraniol and linalool) and EcoRaider^® (commercial product) between pyrethroid susceptible (Harlan) and field collected (Knoxville) bed bug populations. Initially, I found that the Knoxville strain was 72,893 and 291,626 fold resistant to topically applied deltamethrin (a pyrethroid class insecticide) compared to the susceptible Harlan strain at the LD₂₅ and LD₅₀ lethal dose levels, respectively. Synergist bioassays and detoxification enzyme assays showed that the Knoxville strain possesses significantly higher activity of cytochrome P450 and esterase enzymes. Further, Sanger sequencing revealed the presence of the L925I mutation in the voltage gated sodium channel gene. The Knoxville strain, however, did not show any resistance to plant essential oils, their major components or EcoRaider^® in topical bioassays (resistance ratios of ~ 1). In the final objective, I evaluated the efficacy of binary mixtures of above-mentioned essential oils or their major components or EcoRaider^® with deltamethrin in susceptible and resistant bed bugs. In topical application bioassays, binary mixtures of essential oils or their major components or EcoRaider^® and deltamethrin at the LD₂₅ dose caused a synergistic increase in toxicity in resistant bed bugs. Further, I studied the inhibitory effects of major essential oil components on detoxification enzyme activities (cytochrome P450s, esterases and glutathione transferases). Detoxification enzyme assays conducted using protein extracts from bed bugs pre-treated with essential oil constituents showed that these compounds significantly inhibited cytochrome P450 activity in the resistant strain, but esterase and glutathione transferase activity were unaffected. No inhibition of detoxification enzyme activities was observed in the Harlan strain bed bugs pre-treated with essential oil constituents.</p> <p>In conclusion, my dissertation research has created the foundation for utilization of natural products for bed bug management by (i) describing the efficacy of plant essential oils and their components against bed bugs, (ii) discovering synergistic interactions between essential oil components at the nervous system level, (iii) determining susceptibility of deltamethrin-resistant bed bugs to plant essential oils and their constituents and (iv) identifying synergistic effects of essential oils or their components on toxicity of pyrethroid insecticides and underlying mechanisms of this synergistic interaction. </p> <br>

The aspiration of every organization is to collectively gather people in order to perform structured activities to fulfill its purpose. But what if there are circumstances within an organization that interferes with this? The thesis of this study is to scrutinize how employees experience their position in a hierarchical organizational structure, and what management strategies they use to direct and indirect protest against this structure. Through semi-structured interviews, employees have shared their experience of how they cope with being a part of an organization that has, against its own will, a hierarchical organizational structure. By analyzing their empiricism in the context of theories about hierarchy, organization culture and Hirschman’s theory about Exit, Voice and Loyalty, this study concludes that a hierarchical structure roots a barrier between management and its employees. This barrier has caused a lack of trust between these two much needed groups of the organization.                       The employees within the organization that the study is based on, use a varied amount of management strategies due to how they experience their position. These strategies include using their voice for the reason of feeling loyal to the organization, they use their ability to exit the organization for the lack of loyalty, and the employees experience the lack of both voice and exit, because they are finding themselves being dependent of the organization. To manage the rooted barrier and decrease the employees need to use management strategies, management should consider developing a strong organization culture, due to increase trust and motivation among its employees.

Bakgrund: Globalt sett är översvämningar, näst efter stormar, den naturfara som orsakar mest ekonomisk skada. Inom Europeiska unionen (EU) fick översvämningar ett ökat fokus efter att Europa under 2002 drabbades av stora översvämningar. Mot denna bakgrund lanserades i oktober 2012 det EU-finansierade projektet STAR-FLOOD. Projektet mynnade ut i en guidebok för hur översvämningsrisker kan hanteras. I guideboken, skriven av Raadgever m.fl. (2016) rekommenderas en blandning av strategier (diversifiering), för hanteringen av översvämningsrisker. Inom EU har översvämningsrisker traditionellt hanterats genom fysiska skydd, vilket bara är en av flera strategier. I Sverige hanteras översvämningar främst i den akuta fasen och genom privata försäkringar. Översvämningsskydd har först på senare tid fått allt större betydelse för hur översvämningar hanteras i Sverige, något som kan exemplifieras genom den vall som ska byggas på Falsterbonäset i Vellinge kommun i sydvästra Skåne. Det finns en paradox med den typen av strukturella översvämningsskydd och det är att skydden faktiskt kan öka översvämningsrisken. Paradoxen kallas för levé-effekten och innebär att strukturella översvämningsskydd kan leda till en falsk trygghet hos dem som bor i det skyddade området. En diversifierad strategi för hantering av översvämningsrisker kan däremot minska risken för att levé-effekten uppstår. Syfte: Att studera i vilken mån en diversifierad strategi kan spåras i fallet med det planerade översvämningsskyddet på Falsterbonäset. Metod: En beskrivande fallstudie av hur översvämningsrisker från havet hanteras på Falsterbonäset. Materialet har i huvudsak samlats in genom kvalitativa intervjuer som sedan analyserats med riktad kvalitativ innehållsanalys. Som komplement till intervjuerna har även annat material analyserats, främst kommundokument. Den teori som studien grundas på är levé-effekten och teorin om riskhomeostas. Resultat: Mot bakgrund av guideboken skriven av Raadgever m.fl. (2016) är det möjligt för Vellinge kommun att vidta fler strategier för att minska sannolikheten för och konsekvenserna av översvämningar på Falsterbonäset. Exempelvis hade det varit möjligt att begränsa utvecklingen i det skyddade området och ställa tydliga krav på plushöjder för nybyggnation. Samtidigt har kommunens strategi aldrig varit så diversifierad som nu med anledning av det kommande översvämningsskyddet. Avslutningsvis finns det vissa indikationer på att en levé-effekt kan uppstå. / Background: In a global perspective are floods, after storms, the natural hazard that causes the most economic damage. Within the European Union (EU), floods gained increased focus after Europe was hit by major floods in 2002. Because of this, the EU-funded project STAR-FLOOD was launched in October 2012. Among other things, the project resulted in a guidebook for how flood risks can be managed. The guidebook, written by Raadgever et.al. (2016), recommends a mix of strategies (diversification) for the management of flood risks. Within the EU, flood risks have traditionally been managed through structural protection, being just one of several strategies. In Sweden, floods are managed mainly in the acute phase and through private insurance. Flood protection has recently become increasingly important for how floods are handled in Sweden, which can be exemplified by the levee that is to be built on Falsterbonäset in Vellinge municipality in Skåne. However, there is a paradox with this type of structural flood protection, and it is that these can increase the risk of flooding. The paradox is called the levee effect and means that structural flood protection can lead to a false sense of security in those who live in the protected area. A diversified strategy for managing flood risks can reduce the risk of the levee effect. Purpose: Study to which extent a diversified strategy can be traced in the case of structural protection that is planned structural on Falsterbonäset. Method: A descriptive case study of how flood risks from the sea are managed on Falsterbonäset. The material has mainly been collected through qualitative interviews which have then been analysed with a directed qualitative content analysis. As a complement to the interviews, other material has also been analysed, mainly municipal documents. The theory on which the study is based, is the levee effect and the theory of risk homeostasis. Results: Based on the guidebook by Raadgever et.al. (2016), it is possible for Vellinge municipality to do more to reduce the probability and the consequences of floods on Falsterbonäset. For example, it would have been possible to limit the development in the protected area and set clear requirements for heights for new buildings. At the same time, the municipality's strategy has never been as diversified as it is now, due to the forthcoming flood protection. However, there are some indications of conditions for a levee effect to occur.
