The aim was to analyze the process of OBP of women in situations of domestic violence. The method was a clinical study of the psychoanalytic approach that is based on the study of descriptive case study. Participants performed five diagnostic interviews and were also classified with severe ineffective adaptation featuring most limiting neurotic symptoms, inhibitions and restrictive rigidity of character traits. They went through OBP and after the end of the process the Follow up interviews were reassessed by EDAO. The data that was obtained in follow-up interviews showed that there was a change in adaptive efficiency. Participants were also classified with Moderate Inefficient Adaptation. They had some neurotic symptoms, moderate inhibition, some character traits. Our conclusion is that in the studied cases, though the analysis by sectors, the affective relational sector has established itself as a source of conflict and dissatisfaction bringing very few appropriate solutions, decisively influencing other sectors of adaptation. In addition, we observed the phenomenon of reproduction models of the past in the established relations in the present. In both studied cases there was a situation of physical and sexual abuse, which was configured as an inheritance coming from a relational dynamic of the family of origin and perpetuated freely in their nuclear families. Finally, it should be noticed that the patients participated actively during the therapeutic process. From the theorized interpretations, they were able to reconsider their attitudes towards problematic situations experienced and they were able to take some concrete steps to deal with them more adequately during and after the psychotherapeutic process. It was found that the process of brief psychotherapy and the use of operationalized theorized interpretations seem to have contributed to the change in the quality of adaptive efficacy of two women who took part in this study. / A presente pesquisa foi realizada com duas mulheres em situação de violência doméstica e fundamentou-se nos pressupostos teóricos, técnicos e metodológicos da intervenção psicológica intitulada PBO- Psicoterapia Breve Operacionalizada. O objetivo foi analisar o processo da PBO de mulheres em situação de violência doméstica. Para a realização do diagnóstico adaptativo operacionalizado utilizou-se como instrumento a EDAO - Escala Diagnóstica Adaptativa Operacionalizada. O método utilizado foi o estudo clínico de abordagem psicanalítica que tem como base o estudo descritivo do tipo estudo de caso. As participantes realizaram cinco entrevistas diagnósticas e foram classificadas igualmente com adaptação ineficaz severa apresentando sintomas neuróticos mais limitadores, inibições restritivas e rigidez de traços caracterológicos. Elas foram encaminhadas para um atendimento em PBO. Após o final do processo realizou-se as entrevistas de Follow up que foram novamente avaliadas por meio da EDAO. Os dados obtidos nas entrevistas de follow up mostraram que houve mudança na eficácia adaptativa. As participantes foram classificadas igualmente com Adaptação Ineficaz Moderada. Elas apresentavam alguns sintomas neuróticos, inibição moderada, alguns traços caracterológicos. Conclui-se que nos casos estudados, na análise por setores, pôde-se perceber que o setor afetivo relacional constituiu-se como uma fonte de conflitos e insatisfações gerando soluções em sua maioria pouquíssimas adequadas, obviamente, influenciando decisivamente os demais setores da adaptação. Também, observou-se o fenômeno da reprodução de modelos do passado nas relações estabelecidas no presente. Nos dois casos estudados houve uma situação de violência física e de abuso sexual, que se configurava como uma herança provinda de uma dinâmica relacional da família de origem e se perpetuava livremente em suas famílias nucleares. Por último, cabe assinalar que as pacientes participaram de forma ativa durante o processo terapêutico. A partir das interpretações teorizadas foram capazes de reconsiderarem suas atitudes frente às situações-problema vividas e puderam, durante e após o processo psicoterapêutico, adotar algumas medidas concretas para enfrentá-las de forma mais adequada. Conclui-se que o processo de psicoterapia breve operacionalizado e a utilização das interpretações teorizadas parecem ter contribuído para a mudança na qualidade da eficácia adaptativa das duas mulheres que fizeram parte deste estudo.

Projektarbetsformen blir allt vanligare samtidigt som fler och fler organisationer arbetar i projektform. Inom dessa multiprojektmiljöer bör man kontinuerligt säkerställa att kunskap och erfarenheter förs vidare mellan olika projekt för att bli framgångsrik inom sin marknad. Trots att fördelarna med kunskapsöverföring länge erkänts i projektbaserade organisationer så varierar effektiviteten kring fenomenet. Detta tros bland annat bero på svårigheterna med att gå från teori till praktik samt att de modeller och teorier som finns saknar struktur för själva genomförandet. Efter ett försök att kartlägga litteraturen inom detta mångfacetterade fält hittade vi en kunskapslucka angående hur kunskapsöverföring kan te sig inom tv-branschen. Därfär har en kvalitativ fallstudie gjorts på ett tv-produktionsbolag. Studien syftar till att bidra till ökad förståelse kring hur kunskap överförs mellan projekt samt hur man säkerställer kunskapsöverföring. Studien utgår ifrån att kunskap definieras enligt Nonaka och Takeuchis (1995) teori om implicit och explicit kunskap. Studien bygger på kvalitativ forskning i form av sex intervjuer med projektledare och VD, två fokusgrupper med tio projektanställda samt en dokumentanalys på överlämningar skrivna av projektdeltagare. Resultatet visar att det finns många olika typer av kunskapsöverföring inom organisationen. Den kunskap som överförs mellan projekt i organisationen är mestadels kunskap med explicit karaktär i form av dokument. I dagsläget är det huvudsakligen projektledarna som ansvarar för att kunskapsöverföring sker mellan projekt, i huvudsak genom att uppmana projektdeltagare att göra skriftliga överlämningar. Hos projektdeltagarna finns det god vilja att bidra till kunskapsöverföringen men organisationen saknar en huvudsaklig strategi. Slutsatserna konstaterar att ledningen bör implementera ett systematiskt arbetssätt angående organisationens kunskapsöverföring för ett effektivt arbete mot ett organisatoriskt lärande. Slutsatserna belyser även att synen på kunskap är mångtydig och att det handlar om mer än bara explicit och implicit kunskap. För att diskussionen om kunskapsöverföringen inom organisationen ska kunna utvecklas måste organisationen identifiera kunskapstyperna ytterligare samt förstå dessa för att konkretisera dem. / Project work is becoming more common as more and more organizations are working in project form. Within these multi-project environments, one should continuously ensure that knowledge and experience are passed on between different projects in order to be successful in their markets. Although the benefits of knowledge transfer have long been recognized in projectbased organizations, the effectiveness of the phenomenon varies. This is believed to be due, among other things, to the difficulties in moving from theory to practice as well as to the existing models and theories lacking a structure for implementation. Following an attempt to map the literature in this multifaceted field we found a gap in knowledge regarding how knowledge transfer can look within the television industry. Therefore, a qualitative case study has been done at a television production company. This study aims to contribute to an increased understanding of how knowledge is transferred between projects and how to ensure knowledge transfer. The study assumes that knowledge is defined in accordance with Nonaka and Takeuchi’s (1995) theory of implicit and explicit knowledge. This study is based on qualitative research in the form of seven interviews with project managers and CEO, two focus groups with ten project employees and a document analysis submission written by project participants. The result shows that there are many different types of knowledge transfer within the organization. The knowledge that is transferred between projects in the organization is mainly knowledge with explicit character in the form of documents. Currently the project managers are responsible for the transfer of knowledge between projects, which is done by inviting project participants to make written submissions. The project participants are glad to contribute to the transfer of knowledge, but the organization lacks a main strategy. The conclusions state that management should implement a systemic approach to the organization’s knowledge transfer for effective work towards organizational learning. The conclusions also highlight that the view on knowledge is ambiguous and that it is about more than just explicit and implicit knowledge. In order for the discussion of knowledge transfer within the organization to develop, the organization must further identify the types of knowledge and understand them in order to make them concrete.

Catalysis using nanostructures has been a topic of substantial interest for fundamental studies and for practical applications in energy and environmental sectors. The growing demand for production of energy and in the cleaning of polluting hazardous vehicles/industrial wastes has led to several studies in catalysis. Despite the substantial growth of heterogeneous catalytic technologies in last decade, they are still far from reaching their full potential in terms of efficiency, selectivity as well as durability. It is often difficult to simultaneously tackle all the mentioned issues with single component catalysts. Most of these challenges are being overcome with heterostructures/supported hybrid catalysts by modifying their interfaces. The properties of heterostructures hybrids arises not only from the individual contributions of the individual components but also from strong synergetic effect arising from the interface. Engineering the interfaces provides pathways to promote the catalytic performance and hence has been explored. In this regard, we have focused on the progress in investigating the active interfaces that affect the performance of metal oxide-metal, semiconductor-metal and coupled semiconductor nanocatalyst hybrids. We explored a wide spectrum of their applications in photo catalytic, electrocatalytic as well as gas-phase reactions and highlighted the importance of the interface for overall performance. The entire study reported in the thesis is organized as follows: Chapter 1 is a general introduction of hybrid nanocatalyst and their role in wide spectra of catalytic reactions in photo/electro catalysis as well as gas-phase reactions. This chapter describes the motivation behind modulating the interface between two or more nanostructures to obtain multifunctional nanocatalysts. Nan catalysts to achieve high throughput with active interfaces are elaborated while indicating the role of morphology, internal induced state, charge transfer, geometric, support, as well as electronic effect for enhanced performance. Motivation behind specific nanocatalyst hybrid, synthesis routes as well as characterization techniques are detailed in the respective chapters. Specific details for different hybrids are described in the following chapters. Chapter 2 describes the synthesis of high dense ultrathin Au wires on ZnO nanorods for electrocatalytic oxidation of ethanol, where the prerequisite step is the formation of amine-modified support. Oleylamine modification not only serves to anchor Au nanowires on ZnO but also passivates surface defects of ZnO, which in turn enhances the photocurrent. In addition to the stability, the support induces electronic effect on Au nanowires, which facilitates redox process at low potential. Most importantly, the support promotes the activity of Au nanowires upon photoirradiation, and thus leading to synergy between electro and photooxidation current. This is of immense importance for photofuel cell technologies. Moreover, the method enabled the first time electrocatalysis on these nanowires that revealed ultrathin nanowires are potentially interesting systems for catalysis applications provided they are stabilized by a suitable support. Chapter 3 deals with the growth of ultrathin Au nanowires on metal oxide (TiO2) coupled with graphene hybrid support in order to overcome the low conductivity of metal oxide. Oleylamine, used for growth of Au nanowires simultaneously functionalizes the support and leads to room temperature GO reduction. With respect to catalytic activity, we also synthesized the binary counterparts (rGO/Au, TiO2/Au ultrathin nanowires) to delineate the contribution of each of the components to the overall electrocatalytic oxidation of ethanol. Comparative analysis of photo and electrocatalytic activity between the different binary and ternary hybrids provides interesting information. Both, electronic effect of TiO2 and electrical conductivity of rGO add their specific beneficial to the nanowires, leading to superior ternary system. Chapter 4 rGO supported ultrathin Au nanowires exhibits high electrocatalytic performance for oxidation of borohydride with a lower onset potential compared to rGO/Au nanoparticles. Electrochemical impedance spectroscopy measurements display abnormal inductive behavior of the synthesized hybrids, indicative of Au surface reactivation. DFT calculations indicate that the origin of the high activity stems from the shift in the position of the Au d-band center. Chapter 5 Different aspect ratio ZnO nanostructures are obtained by varying the solvothermal reaction time. We observed a direct correlation between observed photocatalytic activity, measured photocurrent and length of the ZnO nanorods. Furthermore, photoresponse of the high aspect ratio ZnO nanorods are improved by attaching Au nanoparticles, intimate contact of two components leads to band bending. Thus, the synthesized ZnO/Au heterostructure favors for prominent separation of photogenerated charge carriers. Chapter 6 TiO2 and PbO/TiO2 hybrids are synthesized via non–hydrolytic sol–gel combustion method. Hybrid exhibits higher photocatalytic activity for the degradation of dye than TiO2. The estimated photogenerated species reveals that the origin of enhanced activity stems from the direct oxidization of dye via photogenerated hole rather than radicals. The semiconductors are matched based on their band edge positions, for the formation of energetic radicals to degrade the pollutants. Based on this study, we infer that semiconductors should not neglected (for example Si) based on calculated mismatch of their valence band edges position for photooxidation reaction via radicals. Chapter 7 describes the Pd dopant associated band engineering, a strategy for tuning the optoelectronic properties of ZnO towards enhanced photocatalytic activity. Incorporated Pd heterocation induces internal energy states within the ZnO band gap. The created energy level leads to trends mismatch between photocatalytic activity and measured photocurrent. Formed energy level arrests the photogenerated electrons, which make them not contribute for the photocurrent generation. Hence, the isolated photogenerated hole efficiently oxidizes the pollutants through hydroxyl radicals, and thus leads to enhanced photocatalytic activity. Chapter 8 employed Pd-substituted zinc stannate for CO oxidation as heterogeneous catalyst for the first time. Compared with SnO2 support, zinc stannate based materials exhibits abnormal sudden light-off profiles at selective temperatures. On the basis of DRIFT studies under relevant conditions, we find that the initially formed product gets adsorbed over the catalyst surface. It leads to the accumulation of carbonates as a consequence, both lattice oxygen mobility and further CO interactions are disabled. As soon as Sn redox nature dominates over the accumulated carbonates, this leads to sudden release of lattice oxygen, and thus leads to a sudden full conversion. Therefore, choosing the suitable support material greatly influences the nature of the light-off CO oxidation profile. Chapter 9 Although, reducible oxide supported gold nanostructures exhibits the highest CO oxidation activity; they still suffer from problems such as limited selectivity towards CO in the presence of H2. Both ex-situ and in-situ experiments demonstrate that, Au nanoparticles supported on Zn2SnO4 matrix selectively oxidizes CO. DRIFT experiments revealed that the involvement of OH groups leads to the formation of hydroxycarbonyl under PROX conditions. Chapter 10 This chapter discusses the conclusions for the previous chapters and highlights the possibilities for future scope for the developed nanocatalysts hybrids for energy and environmental applications.

The focus of strategy research has long revolved around strategy formulation rather thanstrategy implementation, despite the evidence indicating that intended strategies are rarelyachieved. Project portfolio management, PPM, assumes a crucial role in enabling strategyimplementation and can be regarded as a representation of the organization's actual pursuedstrategy. Existing research on PPM has predominantly centered around portfolios in the contextof new product development, NPD, and research and development, R&D. However, there hasbeen relatively less exploration of PPM within internal development departments, warrantingfurther investigation. To contribute to the understanding on strategy implementation throughPPM and its conditional factors, this qualitative case study expands the existing research bystudying the PPM process within an internal development department. The study wasconducted at the Business Improvement department, which oversees improvement projects forthe service branch of EnergyComp, a company specializing in the development of complexenergy solutions. Using an abductive research approach, a literature review was conducted inparallel with data collection and analysis. The empirical data was mainly collected throughsemi-structured interviews at the company, but also through meetings and companydocumentation. The results of the study show that PPM actions connected to projects, portfolio and resourceallocation are undertaken to effectively implement the organization's strategy within theinternal development department. Common to all areas is the importance of accurate andavailable information that effects the decisions connected to strategy implementation. On aproject level, Insufficient information poses challenges in accurately assessing project success,resulting in measurements that fail to cover all strategic objectives. In the context of theportfolio, the absence of project information and uncertainties can lead to a misalignmentbetween the actual prioritization criteria employed in the selection process and the strategicobjectives of the organization. Additionally, it may contribute to a less detailed and formalstrategic plan. Furthermore, the cost associated with adjusting the portfolio is directly linked tothe effort and expenses involved in obtaining project information. Regarding resources,insufficient information on supply and demand creates challenges in considering projectdependencies and synergies during the evaluation of project groups. Moreover, limitedtransparency across functional boundaries within the organization leads to a system wheredecision rules cannot be established at the portfolio level. Instead, it encourages bottom-uppriority decisions. Furthermore, a biased assessment by stakeholders in the functionaldepartments may result in an inadequate screening process, leading to an increased workloadin the portfolio structuring process. Finally, the large variation in project types, coupled withdiverse impact targets spanning individual and multiple functions, makes it difficult to createrelevant project categories for budgeting and portfolio structuring.
