High-power diode laser in the disinfection in depth of the root canal dentin

Objective. The objective of this study was to evaluate the disinfection degree of dentine caused by the use of diode laser after biomechanical procedures. Study design. Thirty teeth were sectioned and roots were autoclaved and incubated for 4 weeks with a suspension of Enterococcus faecalis. The specimens were randomly divided into 3 groups (n = 10): G1, instrumented with rotary files, irrigated with 0.5% sodium hypochlorite and 17% EDTA-T, and then irradiated by 830-nm diode laser at 3 W; G2, the same procedures as G1 but without laser irradiation; and G3, irrigation with saline solution (control). Dentin samples of each third were collected with carbide burs and aliquots were sowed to count viable cells. Results. The disinfection degree achieved was 100% in G1 and 98.39% in G2, when compared to the control group (G3). Conclusion. Diode laser irradiation provided increased disinfection of the deep radicular dentin in the parameters and samples tested.

Sex, a one mans show : Perceptions and experience of sexuality, contraceptives, unwanted pregnancy and unsafe abortion among young people in Kisumu, Kenya – A qualitative study

This study aimed to explore perceptions and experiences concerning sexuality, contraceptives, unwanted pregnancy and unsafe abortion among young people in Kisumu, Kenya. The design of the study was inductive with a qualitative approach using personal in-depth interviews. Eight participants (four female and four male) were asked to describe their perceptions and experience concerning sexuality, contraceptives, unwanted pregnancies and unsafe abortion. The result showed that culture and norms, misconceptions and gender based power in sexuality are factors that impact Sexual Reproductive Health among young people in Kisumu today. Unwanted pregnancy was described as a shame, a burden and a destroyed life which lead to many unsafely induced abortions. The findings indicate that youth interventions are important, such as engaging young men in unwanted pregnancy and thus unsafe abortions and to empower young women.

Perceptions of climate change at ski resorts in midsouth of Sweden

Climate change as a phenomenon will imply new risks for the ski industry. Intergovernmental Panal on Climate Change presents three future scenarios, during the periods between 1990-2100, in forms of increased temperatures, a rise in the sea level and seasonal variations, variables out of which two have direct impacts on the ski industry. The aim for this study was to explore and compare attitudes towards climate change between five ski resorts located in mid-south of Sweden. This was done through in depth interviews in both face to face and by telephone. The result of the study was that all the chosen ski resorts were aware of climate change as a phenomenon but have not yet recognized its consequences. All ski resorts use methods to maintain skiing i.e. artificial snow production though not because of climate change.

The core characteristics and nursing care activities in psychiatric intensive care units in Sweden

Internationally, research on psychiatric intensive care units (PICUs) commonly reportsresults from demographic studies such as criteria for admission, need for involuntary treatment, andthe occurrence of violent behaviour. A few international studies describe the caring aspect of thePICUs based specifically on caregivers’ experiences. The concept of PICU in Sweden is not clearlydefined. The aim of this study is to describe the core characteristics of a PICU in Sweden and todescribe the care activities provided for patients admitted to the PICUs. Critical incident techniquewas used as the research method. Eighteen caregivers at a PICU participated in the study bycompleting a semistructured questionnaire. In-depth interviews with three nurses and two assistantnurses also constitute the data. An analysis of the content identified four categories that characterizethe core of PICU: the dramatic admission, protests and refusal of treatment, escalating behaviours, andtemporarily coercive measure. Care activities for PICUs were also analysed and identified as controlling– establishing boundaries, protecting – warding off, supporting – giving intensive assistance, andstructuring the environment. Finally, the discussion put focus on determining the intensive aspect ofpsychiatric care which has not been done in a Swedish perspective before. PICUs were interpreted asa level of care as it is composed by limited structures and closeness in care.

Barriers and facilitators in the provision of post-abortion care at district level in central Uganda : a qualitative study focusing on task sharing between physicians and midwives

Background: Abortion is restricted in Uganda, and poor access to contraceptive methods result in unwanted pregnancies. This leaves women no other choice than unsafe abortion, thus placing a great burden on the Ugandan health system and making unsafe abortion one of the major contributors to maternal mortality and morbidity in Uganda. The existing sexual and reproductive health policy in Uganda supports the sharing of tasks in post-abortion care. This task sharing is taking place as a pragmatic response to the increased workload. This study aims to explore physicians' and midwives' perception of post-abortion care with regard to professional competences, methods, contraceptive counselling and task shifting/sharing in post-abortion care. Methods: In-depth interviews (n = 27) with health care providers of post-abortion care were conducted in seven health facilities in the Central Region of Uganda. The data were organized using thematic analysis with an inductive approach. Results: Post-abortion care was perceived as necessary, albeit controversial and sometimes difficult to provide. Together with poor conditions post-abortion care provoked frustration especially among midwives. Task sharing was generally taking place and midwives were identified as the main providers, although they would rarely have the proper training in post-abortion care. Additionally, midwives were sometimes forced to provide services outside their defined task area, due to the absence of doctors. Different uterine evacuation skills were recognized although few providers knew of misoprostol as a method for post-abortion care. An overall need for further training in post-abortion care was identified. Conclusions: Task sharing is taking place, but providers lack the relevant skills for the provision of quality care. For post-abortion care to improve, task sharing needs to be scaled up and in-service training for both doctors and midwives needs to be provided. Post-abortion care should further be included in the educational curricula of nurses and midwives. Scaled-up task sharing in post-abortion care, along with misoprostol use for uterine evacuation would provide a systematic approach to improving the quality of care and accessibility of services, with the aim of reducing abortion-related mortality and morbidity in Uganda.

Negotiating collective and individual agency : a qualitative study of young women's reproductive health in rural India

The societal changes in India and the available variety of reproductive health services call for evidence to inform health systems how to satisfy young women's reproductive health needs. Inspired by Foucault's power idiom and Bandura's agency framework, we explore young women's opportunities to practice reproductive agency in the context of collective social expectations. We carried out in-depth interviews with 19 young women in rural Rajasthan. Our findings highlight how changes in notions of agency across generations enable young women's reproductive intentions and desires, and call for effective means of reproductive control. However, the taboo around sex without the intention to reproduce made contraceptive use unfeasible. Instead, abortions were the preferred method for reproductive control. In conclusion, safe abortion is key, along with the need to address the taboo around sex to enable use of "modern" contraception. This approach could prevent unintended pregnancies and expand young women's agency.

Healthcare providers balancing norms and practice : challenges and opportunities in providing contraceptive counselling to young people in Uganda - a qualitative study

BACKGROUND: Pregnancies among young women force girls to compromise education, resulting in low educational attainment with subsequent poverty and vulnerability. A pronounced focus is needed on contraceptive use, pregnancy, and unsafe abortion among young women. OBJECTIVE: This study aims to explore healthcare providers' (HCPs) perceptions and practices regarding contraceptive counselling to young people. DESIGN: We conducted 27 in-depth interviews with doctors and midwives working in seven health facilities in central Uganda. Interviews were open-ended and allowed the participant to speak freely on certain topics. We used a topic guide to cover areas topics of interest focusing on post-abortion care (PAC) but also covering contraceptive counselling. Transcripts were transcribed verbatim and data were analysed using thematic analysis. RESULTS: The main theme, HCPs' ambivalence to providing contraceptive counselling to sexually active young people is based on two sub-themes describing the challenges of contraceptive counselling: A) HCPs echo the societal norms regarding sexual practice among young people, while at the same time our findings B) highlights the opportunities resulting from providers pragmatic approach to contraceptive counselling to young women. Providers expressed a self-identified lack of skill, limited resources, and inadequate support from the health system to successfully provide appropriate services to young people. They felt frustrated with the consultations, especially when meeting young women seeking PAC. CONCLUSIONS: Despite existing policies for young people's sexual and reproductive health in Uganda, HCPs are not sufficiently equipped to provide adequate contraceptive counselling to young people. Instead, HCPs are left in between the negative influence of social norms and their pragmatic approach to address the needs of young people, especially those seeking PAC. We argue that a clear policy supported by a clear strategy with practical guidelines should be implemented alongside in-service training including value clarification and attitude transformation to equip providers to be able to better cater to young people seeking sexual and reproductive health advice.

Japanese Expatriate Managers in Japanese Subsidiaries in Brazil: Why Not Learning-driven?

It has been said that international assignments are traditionally “demand- driven” (DD) that is a way of expatriation of executives focused on control, solution of problems and transference of tacit knowledge. Besides that, according to the international literature, “adjustment” is the determinant factor for success in overseas assignments and Japan usually sends their own executives to subsidiaries in other developing countries for “DD” purpose. However, according to the initial empirical study and in-depth interviews, it seems that Japanese expatriate managers in Brazil were sent to learn how to adjust the local staff to their philosophy instead of adjust themselves to a new complete scenario. This paper found that “adjustment” would not be fundamental for Japanese expatriate manager’s success in their assignments to Brazil, since they were under a special “learning-driven” type of expatriation process. This paper also highlights the challenges of the Japanese expatriate managers in Brazil and their contribution to the development of local staff under the internationalization process.

The human side of project management - an investigation of critical chain concepts in the Argentinean Project Environment

The global marketplace is rapidly intensifying. Longer product sales lives, greater profit margins or simply survival, is dependent on management¿s ability to create and lead change. Project Management has become an important competency, combined with other business practices to adapt to the trend of changing conditions. Critical Chain is a relatively new project methodology, elaborated by Eliyahu Goldratt in order to complete projects faster, make more efficient use of resources and securing the project deliverables. The methodology is based on the assumption that traditional project techniques such as CPM and PERT, do not recognize critical human behavior. The methodology claims that many project failures are a direct result of how safety is built into the task delivery times, and then wasted by human behavior such as Student Syndrome, Parkinson Law and Multitasking. However, there has been little or no previous research regarding this topic in the Argentine marketplace. This study intended to investigate to what extent the human behavior concepts of critical chain project management are present, by performing in-depth interviews with Argentine project stakeholders. It appears that the four human behavior concepts are present in Argentina and that the majority of Argentine companies are yet to apply project management techniques.

Distribution strategies for the base of the pyramid: an exploratory study in Brazil

Access has been one of the main difficulties companies have faced in emerging markets (PRAHALAD, 2005). The capillarity of the market, the existence of small, not professionalized and sometimes informal retailers, the lack of infrastructure and high transportation costs are some of the distribution challenges companies face in poorer regions. The literature concerning the Base of the Pyramid (BoP) is still recent and only after the seminal article by Prahalad and Hart (2002), it evolved into many different management perspectives. However, there is a lack of researches concerning distribution strategies to the BoP. Therefore, the main objective of this research is to identify, in the perception of executives working in the market, the conditions associated to a satisfactory distribution for the BoP market in Brazil and to build a substantive theory that helps to shed light to the understanding of the distribution phenomenon adopted by consumer goods companies to reach the BoP market in Brazil. In order to accomplish the objectives of this thesis, a grounded theory methodology (Glaser; Strauss, 1967; Corbin; Strauss, 2008) was used. This approach helped to identify the channel strategies used by local and global companies in the market. Many techniques for data collection were applied. The most important one was in-depth interviews with 26 executives from 24 different consumer goods companies in Brazil. Among the companies there were small, medium and large enterprises; which were also grouped as manufacturers, distributors and retailers. Furthermore, secondary data were examined to identify business strategies to reach BoP and map global distribution initiatives. A database from a consumer panel was also used to analyze what and where BoP consumers purchase non-durable goods. It was verified that small and traditional retailing is a very strong format in BoP markets and in the Northern/Northeastern regions. Cash & Carry is a format that is growing a lot. On the other hand, hypermarkets are not very used by low income population. The results suggest that three major categories are associated to a satisfactory distribution: (a) willingness, which means the effort, knowledge and enthusiasm a firm has to operate at BoP markets; (b) well-done execution, which is related to designing correctly the marketing channel and operating efficiently in an environment full of obstacles, such as lack of infrastructure, capillarity, lack of safety, regional differences and informality, and (c) relationship, which was perceived to be friendlier and essential at BoP markets, since it is very difficult for manufacturers to reach the entire market alone. It is more likely to have a satisfactory distribution when manufacturers establish strong relationships in the marketing channel. Besides, small retailers have a perception of isolation and expect a higher level of relationship. These major categories explain also the competitive advantage that local companies have in relation to MNCs and large companies. Despite of the limitations of an exploratory study, it is expected that this thesis will contribute to the BoP knowledge as well as to the identification of the peculiarities of distribution in BoP markets.

Racial discrimination in Brazil: interviews with leaders of the black movement

Racism in Brazil has some specificities when compared to other countries, for, differently from, for instance, South Africa and the United States, Brazilian Constitutions, ever since the Independence (1822), have never distinguished the citizens according to race or color. Furthermore, since the mid-1900s, Afro-Brazilian cultural manifestations, such as, for example, samba and capoeira, started to be valued as a part of our “national identity”. These specificities make race relations in Brazilian society a much more complex issue. This paper is focused on selected parts of interviews that deal with the nature of racial discrimination in Brazil, extracted from interviews with leaders of the black movement produced within the scope of the project “The History of Black Movement in Brazil: organization of a collection of Oral History Interviews”, developed by CPDOC, Getulio Vargas Foundation (Rio de Janeiro). These “histories within history”, as told by our interviewees, may be transformed into images that will be able to condense a given reality, thus allowing us to evaluate the gains obtained by oral history methodology.

Future cenario planning in Brazilian logistics and transportation sector

Nas últimas décadas o setor de logística passou por grandes transformações pelo mundo. Assim, a eficiência do sistema logístico é importante para o crescimento econômico, a diversificação, redução dos custos operacionais e da pobreza. Segundo o Banco Mundial, o Brasil tornou-se uma das maiores economias do mundo, mas os custos logísticos elevados colocam em risco esse crescimento. Estes custos são em grande parte o resultado de diferenças em infraestrutura de cada região, juntamente com os encargos do setor rodoviário, que corresponde por 60% do total do transporte de carga do país. Entretanto, a logística brasileira está às portas de uma nova revolução, em práticas de negócios e eficiência, e também na qualidade e disponibilidade da infraestrutura de transportes e comunicações, e novos projetos e práticas para superar a situação. O objetivo deste estudo não é analisar o presente e as atuais tendências de logística do Brasil e do setor de transporte, mas sim modelar possíveis cenários futuros para os próximos anos. Em outras palavras, este trabalho mostra diferentes possibilidades de como o setor de logística e transporte poderá ser no futuro. Para isso, este trabalho irá utilizar a metodologia de cenários prospectivos e entrevistas com especialistas relacionados da área.

Integrating open innovation in the social innovation process: an exploratory study

Inovação tem se tornado um fenômeno cada vez mais complexo e dinâmico, com a mudança de um paradigma focado na inovação industrial, onde a inovação acontecia no produto ou no processo de fabricação, para outro baseado no conhecimento, muito mais amplo. Além disso, o conhecimento e a competência técnica não são mais considerados como um monopólio do departamento de pesquisa e desenvolvimento. Isto trouxe mudanças nas práticas de inovação, que se tornaram mais abertas e levaram as empresas a interagir cada vez mais com o seu ambiente. Por outro lado, a inovação tecnológica, cujo primeiro objetivo é de criar valor para a empresa, tem experimentado alguns limites para resolver problemas sociais, como o aquecimento global. As novas tecnologias têm a capacidade de melhorar a qualidade de vida de muita gente, mas não é suficiente. É nesse contexto que surge outro tipo de inovação, cujo objetivo é de maximizar o impacto positivo na sociedade: a inovação social. Estes dois paradigmas de inovação, mais adequados aos desafios atuais, têm alguns pontos em comum na sua integração com o ambiente externo: a sociedade e outros atores da inovação. No entanto, praticamente não existem estudos integrando inovação aberta e inovação social. Este trabalho estuda a integração destes dois modelos a partir de uma pesquisa exploratória, realizando entrevistas em profundidade com 11 dirigentes de organizações sociais. As iniciativas sociais parecem atrair mais organizações externas para colaborar do que empresas com fins lucrativos, já que são mais altruístas. Parecem integrar essas pessoas e procurar por mais ajuda, especialmente no momento de escalar o negócio. Ainda que algumas organizações têm como prioridade institucionalizar a inovação aberta, outras veem isto como secundário ou simplesmente não sabem como fazer. Isto resulta em uma colaboração mais informal, que não é focada em atividades de pesquisa e desenvolvimento, prática ausente nas empresas da nossa amostra.

Iguatemi: creating opportunities for international luxury brands in Brazil

The Brazilian luxury goods market has been registering substantial growth with many international brands establishing presence in the country. When entering the market, the perfect location seems for most of them to be found in Iguatemi Group’s Shopping Malls. This research focuses the topic of Luxury Market and Retail, in the form of a case study on Iguatemi Group, which tries to understand How is Iguatemi Group creating opportunities for International Luxury Brands in Brazil? To understand the context of the case, the text explores the Brazilian market evolution, its attraction factors and challenges, the location choice methodology used by international luxury brands, and finally, how is the Iguatemi Group creating opportunities for these brands in Brazil. For doing so, a multiple-methods approach was followed so to achieve a non-biased result. In-depth interviews were conducted with Iguatemi’s managers, international luxury brands’ managers and experts in luxury market and retail; non-participant observation was held, and documentation was examined. The research found that the entry of International Luxury Brands in Brazil started about 20 years ago, mainly explained by the positive structural economic reforms Brazil experienced in this period. 60% of the studied brands chose São Paulo’s Iguatemi malls as first location, in particular Iguatemi São Paulo and JK Iguatemi. The preference over these locations relies mainly on the reputation of the Iguatemi brand and on its positioning in the market which seems to be aligned to that of these brands. From its side, Iguatemi has started actively gathering international luxury brands into the market since 15 years ago, and has intensified its action by creating iRetail, an internal company to the group representing some international luxury brands in Brazil, which have, thus, exclusive locations in its malls. The role of Iguatemi, hence, goes beyond that of a real estate company, by approaching the market with a 360° strategy. These findings contribute for academic purposes, in the extent to which they propose a so far rather unexplored topic, and for managerial purposes by describing a best practice in the shopping center sector. However, the study does not mean to be generalized. Consumers’ perspectives on Iguatemi Group were not addressed; rather, the research took a business to business approach.

Growth process in business and social entrepreneurship: the case of Brazil

The purpose of the dissertation is to investigate in depth the difference between the challenges social and business entrepreneurs face in the growth phase of their business in the particular environment of Brazil. This objective has been achieved through a two-steps methodology. The first step is a set of in-depth interviews carried out with industry experts such as professors, venture capitalists, consultants, fund managers or people involved in the support of growing startups (i.e. accelerators). These interviews allowed, first, to build a general perspective on the environment entrepreneurs operate into and to identify a list of challenges entrepreneurs face in the growth process of their business. This list was completed with the additional challenges identified in the previous literature. The second step of the methodology was to test the relevance of these challenges in the mind and experience of social and traditional entrepreneurs. A questionnaire was then submitted to 145 social and 286 traditional entrepreneurs. The results were statistically analyzed to test the relative relevance of these challenges for one group of entrepreneurs with respect to the other. The outcome of the analysis was significant. The most relevant challenges identified were, for both groups, taxation, bureaucracy, finding the right employees, creating effective teams, measuring firm performance and social value creation and obtaining funds. On the other side motivation, innovation, competition and lack of market space for growth represented the least relevant issues in the minds of entrepreneurs. This rank however did not differ significantly from social to traditional entrepreneurs. This testifies that in Brazil social and traditional entrepreneurs face the same set of challenges despite the widespread belief of the opposite.
