Hiljaisen tietämyksen jakamista edistävät yksilötekijät työyhteisössä

Pro gradu -tutkielman tavoitteena oli tutkia yksilöiden välistä hiljaisen tietämyksen jakamista edistäviä tekijöitä. Yksilötason olosuhteiden tunteminen on tarpeen, jotta organisaation toteuttamat toimenpiteet hiljaisen tietämyksen jakamisen tehostamiseksi ovat tarkoituksenmukaisesti kohdennettuja. Työn teoriaosuudessa keskityttiin tarkastelemaan hiljaisen tietämyksen olemusta sekä hiljaisen tietämyksen jakamista yksilöiden välillä. Tutkielman empiirisessä osuudessa edellä mainittuja tekijöitä tarkasteltiin käytännössä ja pyrittiin selvittämään miten yksilön motivaatioon, mahdollisuuksiin, kykyihin sekä kommunikaatioon liittyvät tekijät edistävät hiljaisen tietämyksen jakamista työyhteisössä. Tutkimuksen kohteena oli erityisesti työtehtävissä esiintyvä hiljainen tietämys ja sen jakamiseen liittyvät yksilötason tekijät. Tutkimusaineisto kerättiin haastattelujen ja kyselylomakkeiden avulla. Tutkimuksen perusteella saatiin selkeä kuva siitä, millaiset motivaatioon, mahdollisuuksiin ja kykyihin liittyvät tekijät edistävät hiljaisen tietämyksen jakamista sekä millainen kommunikaatio tukee sitä. Tutkimuksen tulokset osoittivat, että MOA-tekijät ovat merkittävästi vaikuttamassa yksilöiden väliseen hiljaisen tietämyksen jakamiseen. Tulokset tukivat pääosin aiempaa tutkimusta, mutta tuottivat samalla tieteellistä lisäarvoa tuomalla esiin yksityiskohtaisempia havaintoja eri tekijöiden vaikutuksesta hiljaisen tietämyksen jakamiseen. Erityisesti esiin nousivat yksilöiden väliset hyöty- ja etäisyysnäkökulmat.

Organisaation sisäisessä sosiaalisessa mediassa tapahtuvaan tiedon jakamiseen vaikuttavat tekijät

Aineettoman pääoman, erityisesti tiedon, merkitykseen kiinnitetään organisaatioissa entistä enemmän huomiota. Tiedon jakamisen hyödyt ymmärretään ja siinä hyödynnetään yhä enemmän teknologiaa. Tämän tutkielman tavoitteena on selvittää, mitkä tekijät vaikuttavat asiantuntijoiden tiedon jakamiseen organisaation sisäisessä sosiaalisessa mediassa. Tutkimus on kvalitatiivinen tapaustutkimus, ja sen tavoitteisiin pyritään vastaamaan puolistrukturoitujen haastattelujen (12 kpl) avulla. Tutkimuksen kohdeorganisaatio on innovaatiorahoituskeskus Tekes. Tiedon jakamista sisäisessä sosiaalisessa mediassa tutkittiin yksilön näkökulmasta motivaatioon, kykyyn ja mahdollisuuteen perustuvaa MOA-mallia hyödyntäen. Tutkimuksessa löydettiin sekä motivaatioon, kykyyn että mahdollisuuteen liittyviä tekijöitä, jotka vaikuttavat sisäisessä sosiaalisessa mediassa tapahtuvaan tiedon jakamiseen. Motivaatioon liittyvistä tekijöistä nousivat esiin erityisesti jaetun tiedon hyöty asiantuntijan työssä sekä aktiivisten sosiaalisen median käyttäjien määrä, mahdollisuuteen liittyvistä tekijöistä käytettävissä oleva aika sekä tiedon ja tiedon jakamisen kanavien suuri määrä.

Understanding food waste through behavioural theories in different settings

SDG 12.3 aims to promote sustainable consumption and production patterns by addressing the global food loss and waste problem. Given the multiple interrelated impacts, food waste is recognized as one of the major food system challenges. The scope of this work is to contribute to the understanding on food waste generation and potential approaches to tackle it. This work was specifically designed to achieve the following goals: 1) Understand specific factors that affect individual behaviours to generate FW at household, 2) Analyse the effective ways to reduce FW through behaviour change perspective given the catering and hospitality sector, and 3) Provide an evidence synthesis on intervention study that incorporate stakeholder insights focus on school meals. The first goal of identifying food waste drivers was achieved by the systematically reviewing on peer-reviewed and grey literature. The Motivation-Opportunity-Ability (MOA) framework was applied to frame consumer behavioural drivers and identify levers that could be potentially utilized to reduce food waste. Consumer segmentation was further discussed to provide insights for developing tailored food waste reduction interventions. The second goal required the identification on practical interventions, which has been accomplished by systematic literature review basing on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The efficiency and working mechanism of interventions were evaluated basing on the combination of MOA and behavioural change wheel. Building on the evidence of effective interventions, a roadmap was developed for policymakers and practitioners to lead their own pathway on intervention study and upscaling. The third aim has been achieved with a school meals interventions mapping and the implementation of stakeholder workshops. The method was built on the literature review and then enriched by intervention co-design dialogue among stakeholders. The overall conclusion addressed challenges of food waste determents identification, tailored reduction interventions developing, sustainable consumption promotion with school meals.

KIBS-yrityksen konsultin ja asiakkaan väliseen hiljaisen tiedon jakamiseen vaikuttavat tekijät

Tutkielman tavoitteena oli selvittää ja ymmärtää, mitkä tekijät vaikuttavat hiljaisen tiedon jakamiseen asiakkaan ja KIBS-yritystä edustavan konsultin välillä. Tutkimusongelmaa lähestyttiin näkökulmasta, missä hiljaisen onnistuneen jakamisen merkitys nähtiin rekrytointipalvelun onnistumisen edellytyksenä. Sekä kirjallisuuskatsauksessa että tutkimuksen empiirisessä osuudessa pyrittiin selvittämään, miten motivaatio, kykytekijät ja luottamus vaikuttavat hiljaisen tiedon jakamiseen. Tutkimuksessa pyrittiin myös kuvaamaan niitä mahdollisuuksia ja haasteita, mitä hiljaisen tiedon jakaminen synnyttää rekrytointiprosessin määrittelyvaiheessa. Kirjallisuuskatsauksessa tarkasteltiin teorioita tiedosta ja hiljaisen tiedon jakamisesta, sekä määriteltiin pääkäsitteet hiljainen tieto, motivaatio, mahdollisuus, kyvykkyys, luottamus, KIBS-yritys, sekä joukko niiden alakäsitteitä. Tutkimuksen empiirinen osuus toteutettiin laadullisilla menetelmillä tapaustutkimuksena. Aineisto kerättiin kuuden puolistrukturoidun teema-haastattelun kautta. Tiedon jakamiseen vaikuttaviksi ja edistäviksi tekijöiksi tunnistettiin vuoro-vaikutustilanteessa olevien henkilöiden välinen luottamus, motivaatio ja asiantuntemus. Haasteina hiljaisen tiedon jakamisessa nähtiin sen strateginen, sekä toimintaan ja asiantuntemukseen sidoksissa oleva muoto.

Searchig the links between "knowledge governance mechanisms", "the individual conditions of knowledge sharing", and "individual's knowledge sharing behaviour".

The objective of this study was to understand how organizational knowledge governance mechanisms affect individual motivation, opportunity, and the ability to share knowledge (MOA framework), and further, how individual knowledge-sharing conditions affect actual knowledge sharing behaviour. The study followed the knowledge governance approach and a micro-foundations perspective to develop a theoretical model and hypotheses, which could explain the casual relationships between knowledge governance mechanisms, individual knowledge sharing conditions, and individual knowledge sharing behaviour. The quantitative research strategy and multivariate data analysis techniques (SEM) were used in the hypotheses testing with a survey dataset of 256 employees from eleven military schools of Finnish Defence Forces (FDF). The results showed that “performance-based feedback and rewards” affects employee’s “intrinsic motivation towards knowledge sharing”, that “lateral coordination” affects employee’s “knowledge self-efficacy”, and that ”training and development” is positively related to “time availability” for knowledge sharing but affects negatively employee’s knowledge self-efficacy. Individual motivation and knowledge self-efficacy towards knowledge sharing affected knowledge sharing behaviour when work-related knowledge was shared 1) between employees in a department and 2) between employees in different departments, however these factors did not play a crucial role in subordinate–superior knowledge sharing. The findings suggest that individual motivation, opportunity, and the ability towards knowledge sharing affects individual knowledge sharing behaviour differently in different knowledge sharing situations. Furthermore, knowledge governance mechanisms can be used to manage individual-level knowledge sharing conditions and individual knowledge sharing behaviour but their affect also vary in different knowledge sharing situations.

Controlo interno na prevenção de erros e fraudes

Atualmente, as situações de erros e fraudes, têm ocorrido com muita frequência a nível mundial. Por exemplo em Cabo Verde estas têm vindo a ganhar espaço nos mídias, onde a todo momento aparece casos de erros e fraudes, como por exemplo, os casos da Sociedade Cabo-verdiana de Tabacos, Banco Comercial do Atlântico, Caixa Económica, Câmara Municipal da Ribeira Brava, Associação Sport Club Moreirense, Sociedade de Segurança Industrial, Marítima e Comercial, Ministério das Finanças entre outros. Essas situações desfavoráveis para qualquer empresa, são derivadas de uma gestão menos cuidada dos recursos, e dos valores e princípios éticos cultivados pelas pessoas. O triângulo de fraude criada por Donald Cressey demonstra os motivos que leva um individuo a cometer atos fraudulentos, como sendo a motivação, a pressão e a oportunidade. Neste sentido, o controlo interno surge como uma ferramenta muito importante e fundamental para mitigar os riscos advenientes da ocorrência de erros e fraudes, suscetíveis de acontecer nas empresas. O controlo interno traduz num conjunto de medidas que protegem o património da empresa e garantem o cumprimento dos seus objetivos entretanto, como qualquer outra ferramenta de gestão está possui determinadas limitações que podem ser ultrapassadas com a utilização de alguns procedimentos básicos e, ou alternativos de controlo interno. É imprescindível que um sistema de controlo interno, para além de implementado, adequado e em funcionamento, seja mantido e acompanhado. O estudo dos casos da SILMAC, SA e da SCT, SA, mostram a importância que o controlo interno tem na prevenção e deteção de erros e fraudes, pois denota-se que as fraudes cometidas aconteceram na sequência de fraquezas de controlo interno e no excesso de confiança depositada nos colaboradores. Currently, the situations of errors and fraud have occurred very often in the world. Cape Verde in these situations have gained ground in the media, where every moment appears to errors and fraud cases, such as cases of “Sociedade cabo-verdiana de tabacos, Banco Comercial do Atlântico, Caixa Económica, Câmara Municipal da Ribeira Brava, Associação Sport Club Moreirense, Sociedade de segurança industrial, marítima e comercial, Ministério de finanças” amongst others. These situations which unfavorable for any company, are derived from a less carefully management of resources and ethical principles and values cultivated by people. The fraud triangle created by Donald Cressey, demonstrates reasons that lead an individual to commit fraudulent acts, such as motivation, opportunity and pressure. In this sense, internal control emerges as a very important tool to mitigate the risks arising from situations of errors and fraud, which are likely to happen in companies. The internal control translates into a set of measures that protect the assets of the business and ensure the fulfillment of its objectives however, like any other management tool is has limitations, however these can be overcome with the use of basic procedures, or alternative internal control. It is essential that an internal control system, in addition to implemented, adequate and functioning is maintained and monitored. The case studies of SILMAC and SCT, show the importance of internal control is the prevention and detection of errors and fraud. For note that the fraud occurred following oversights in its internal control and confidence in their employees.

Improving sequence-based fold recognition by using 3D model quality assessment

Motivation: The ability of a simple method (MODCHECK) to determine the sequence–structure compatibility of a set of structural models generated by fold recognition is tested in a thorough benchmark analysis. Four Model Quality Assessment Programs (MQAPs) were tested on 188 targets from the latest LiveBench-9 automated structure evaluation experiment. We systematically test and evaluate whether the MQAP methods can successfully detect native-likemodels. Results: We show that compared with the other three methods tested MODCHECK is the most reliable method for consistently performing the best top model selection and for ranking the models. In addition, we show that the choice of model similarity score used to assess a model's similarity to the experimental structure can influence the overall performance of these tools. Although these MQAP methods fail to improve the model selection performance for methods that already incorporate protein three dimension (3D) structural information, an improvement is observed for methods that are purely sequence-based, including the best profile–profile methods. This suggests that even the best sequence-based fold recognition methods can still be improved by taking into account the 3D structural information.

Effect of fatigue on consumers' advertising processing

Huge advertising budgets are invested by firms to reach and convince potential consumers to buy their products. To optimize these investments, it is fundamental not only to ensure that appropriate consumers will be reached, but also that they will be in appropriate reception conditions. Marketing research has focused on the way consumers react to advertising, as well as on some individual and contextual factors that could mediate or moderate the ad impact on consumers (e.g. motivation and ability to process information or attitudes toward advertising). Nevertheless, a factor that potentially influences consumers’ advertising reactions has not yet been studied in marketing research: fatigue. Fatigue can yet impact key variables of advertising processing, such as cognitive resources availability (Lieury 2004). Fatigue is felt when the body warns to stop an activity (or inactivity) to have some rest, allowing the individual to compensate for fatigue effects. Dittner et al. (2004) defines it as “the state of weariness following a period of exertion, mental or physical, characterized by a decreased capacity for work and reduced efficiency to respond to stimuli.’’ It signals that resources will lack if we continue with the ongoing activity. According to Schmidtke (1969), fatigue leads to troubles in information reception, in perception, in coordination, in attention getting, in concentration and in thinking. In addition, for Markle (1984) fatigue generates a decrease in memory, and in communication ability, whereas it increases time reaction, and number of errors. Thus, fatigue may have large effects on advertising processing. We suggest that fatigue determines the level of available resources. Some research about consumer responses to advertising claim that complexity is a fundamental element to take into consideration. Complexity determines the cognitive efforts the consumer must provide to understand the message (Putrevu et al. 2004). Thus, we suggest that complexity determines the level of required resources. To study this complex question about need and provision of cognitive resources, we draw upon Resource Matching Theory. Anand and Sternthal (1989, 1990) are the first to state the Resource Matching principle, saying that an ad is most persuasive when the resources required to process it match the resources the viewer is willing and able to provide. They show that when the required resources exceed those available, the message is not entirely processed by the consumer. And when there are too many available resources comparing to those required, the viewer elaborates critical or unrelated thoughts. According to the Resource Matching theory, the level of resource demanded by an ad can be high or low, and is mostly determined by the ad’s layout (Peracchio and Myers-Levy, 1997). We manipulate the level of required resources using three levels of ad complexity (low – high – extremely high). On the other side, the resource availability of an ad viewer is determined by lots of contextual and individual variables. We manipulate the level of available resources using two levels of fatigue (low – high). Tired viewers want to limit the processing effort to minimal resource requirements by making heuristics, forming overall impression at first glance. It will be easier for them to decode the message when ads are very simple. On the contrary, the most effective ads for viewers who are not tired are complex enough to draw their attention and fully use their resources. They will use more analytical strategies, looking at the details of the ad. However, if ads are too complex, they will be too difficult to understand. The viewer will be discouraged to process information and will overlook the ad. The objective of our research is to study fatigue as a moderating variable of advertising information processing. We run two experimental studies to assess the effect of fatigue on visual strategies, comprehension, persuasion and memorization. In study 1, thirty-five undergraduate students enrolled in a marketing research course participated in the experiment. The experimental design is 2 (tiredness level: between subjects) x 3 (ad complexity level: within subjects). Participants were randomly assigned a schedule time (morning: 8-10 am or evening: 10-12 pm) to perform the experiment. We chose to test subjects at various moments of the day to obtain maximum variance in their fatigue level. We use Morningness / Eveningness tendency of participants (Horne & Ostberg, 1976) as a control variable. We assess fatigue level using subjective measures - questionnaire with fatigue scales - and objective measures - reaction time and number of errors. Regarding complexity levels, we have designed our own ads in order to keep aspects other than complexity equal. We ran a pretest using the Resource Demands scale (Keller and Bloch 1997) and by rating them on complexity like Morrison and Dainoff (1972) to check for our complexity manipulation. We found three significantly different levels. After having completed the fatigue scales, participants are asked to view the ads on a screen, while their eye movements are recorded by the eye-tracker. Eye-tracking allows us to find out patterns of visual attention (Pieters and Warlop 1999). We are then able to infer specific respondents’ visual strategies according to their level of fatigue. Comprehension is assessed with a comprehension test. We collect measures of attitude change for persuasion and measures of recall and recognition at various points of time for memorization. Once the effect of fatigue will be determined across the student population, it is interesting to account for individual differences in fatigue severity and perception. Therefore, we run study 2, which is similar to the previous one except for the design: time of day is now within-subjects and complexity becomes between-subjects

Added value from biomass by broader utilization of fuels and CHP plants

The present work, where additional value-creating processes in existing combined heat and power (CHP) structures have been examined, is motivated by a political- and consumer-driven strive towards a bioeconomy and a stagnation for the existing business models in large parts of the CHP sector. The research is based on cases where the integration of flash pyrolysis for co-production of bio-oil, co-gasification for production of fuel gas and synthetic biofuels as well as leaching of extractable fuel components in existing CHP plants have been simulated. In particular, this work has focused on the CHP plants that utilize boilers of fluidized bed (FB) type, where the concept of coupling a separate FB reactor to the FB of the boiler forms an important basis for the analyses. In such dual fluidized bed (DFB) technology, heat is transferred from the boiler to the new rector that is operating with other fluidization media than air, thereby enabling other thermochemical processes than combustion to take place. The result of this work shows that broader operations at existing CHP plants have the potential to enable production of significant volumes of chemicals and/or fuels with high efficiency, while maintaining heat supply to external customers. Based on the insight that the technical preconditions for a broader operation are favourable, the motivation and ability among the incumbents in the Swedish CHP sector to participate in a transition of their operation towards a biorefinery was examined. The result of this assessment showed that the incumbents believe that a broader operation can create significant values for their own operations, the society and the environment, but that they lack both a strong motivation as well as important abilities to move into the new technological fields. If the concepts of broader production are widely implemented in the Swedish FB based CHP sector, this can substantially contribute in the transition towards a bioeconomy.

Language Ability and Motivation among Foreigners in Survey Responding

With increasing migration and linguistic diversification in many countries, survey researchers and methodologists should consider whether data provided by individuals with variable levels of command of the survey language are of the same quality. This paper examines the question of whether answers from resident foreign respondents who do not master available survey languages may suffer from problems of comprehension of survey items, especially items that are more complicated in terms of content and/or form. In addition, it addresses the extent to which motivation may affect the response quality of resident foreigners. We analyzed data from two large-scale surveys conducted in Switzerland, a country with three national languages and a burgeoning foreign population, employing a set of dependent measures of response quality, including don't know responses, extreme responding, mid-5 responding, recency effects, and straight-lining. Results show overall poorer response quality among foreigners, and indicate that both reduced language mastery and motivation among foreigners are relevant factors. This is especially true for foreign groups from countries that do not share a common language with those spoken in Switzerland. A general conclusion is that the more distant respondents are culturally and linguistically from the majority mainstream within a country, the more their data may be negatively affected. We found that more complex types of questions do generally lead to poorer response quality, but to a much lesser extent than respondent characteristics, such as nationality, command of the survey language, level of education, and age.

Appetitive motivation predicts the majority of personality and an ability measure: a comparison of BAS measures and a re-evaluation of the importance of RST

Our first study develops a measure of appetitive motivation and our second study compares several measures of Gray's (1987) behaviour activation system (BAS) in the prediction of the surface scales of personality. In particular, we were interested in determining the utility of the new appetitive motivation scale and Dickman's functional impulsivity scale. In comparison to other well-known measures, both scales were generally good predictors. We conclude that the appetitive motivation scale is a promising measure of BAS based upon construct validation. Contrary to previous studies which have suggested that BAS is a generally poor predictor of the surface scales of personality, we discovered appetitive motivation to be an important predictor of personality in general. Interestingly, the scale was also predictive of scores on the Baddeley reasoning test. (C) 2003 Elsevier Ltd. All rights reserved.

eHealth e a adoção da inovação em assisted living technologies : o caso das demências

RESUMO - Assistimos hoje a um contexto marcado (i) pelo progressivo envelhecimento das sociedades ocidentais, (ii) pelo aumento da prevalência das doenças crónicas, de que as demências são um exemplo, (iii) pelo significativo aumento dos custos associados a estas patologias, (iv) por orçamentos públicos fortemente pressionadas pelo controlo da despesa, (v) por uma vida moderna que dificulta o apoio intergeracional, tornando o suporte proporcionado pelos filhos particularmente difícil, (vi) por fortes expectativas relativamente à prestação de cuidados de saúde com qualidade. Teremos assim de ser capazes de conseguir melhorar os serviços de saúde, ao mesmo tempo que recorremos a menos recursos financeiros e humanos, pelo que a inovação parece ser crítica para a sustentabilidade do sistema. Contudo a difusão das Assistive Living Technologies, apesar do seu potencial, tem sido bastante baixa, nomeadamente em Portugal. Porquê? Hamer, Plochg e Moreira (2012), no editorial do International Journal of Healthcare Management, enquadram a Inovação como “podendo ser imprevisível e mesmo dolorosa, pelo que talvez possamos não ficar surpreendidos se surgirem resistências e que, inovações bastante necessárias, capazes de melhorar os indicadores de saúde, tenham sido de adoção lenta ou que tenham mesmo sido insustentáveis”. Em Portugal não há bibliografia que procure caracterizar o modelo de difusão da inovação em eHealth ou das tecnologias de vivência assistida. A bibliografia internacional é igualmente escassa. O presente projeto de investigação, de natureza exploratória, tem como objetivo principal, identificar barreiras e oportunidades para a implementação de tecnologias eHealth, aplicadas ao campo das demências. Como objetivos secundários pretendemse identificar as oportunidades e limitações em Portugal: mapa de competências nacionais, e propor medidas que possa acelerar a inovação em ALT, no contexto nacional. O projeto seguirá o modelo de um estudo qualitativo. Para o efeito foram conduzidas entrevistas em profundidade junto de experts em ALT, procurando obter a visão daqueles que participam do lado da Oferta- a Indústria; do lado da Procura- doentes, cuidadores e profissionais de saúde; bem como dos Reguladores. O instrumento utilizado para a recolha da informação pretendida foi o questionário não estruturado. A análise e interpretação da informação recolhida foram feitas através da técnica de Análise de Conteúdo. Os resultados da Análise de Conteúdo efetuada permitiram expressar a dicotomia barreira/oportunidade, nas seguintes categorias aqui descritas como contextos (i) Contexto Tecnológico, nas subcategorias de Acesso às Infraestruturas; Custo da Tecnologia; Interoperabilidade, (ii) Contexto do Valor Percecionado, nas subcategorias de Utilidade; Eficiência; Divulgação, (iii) Contexto Político, compreendendo a Liderança; Organização; Regulação; Recursos, (iv) Contexto Sociocultural, incluindo nomeadamente Idade; Literacia; Capacidade Económica, (v) Contexto Individual, incluindo como subcategorias, Capacidade de Adaptação a Novas tecnologias; Motivação; Acesso a equipamentos (vi) Contexto Específico da Doença, nomeadamente o Impacto Cognitivo; Tipologia Heterogénea e a Importância do Cuidador. Foi proposto um modelo exploratório, designado de Modelo de Contextos e Forças, que estudos subsequentes poderão validar. Neste modelo o Contexto Tecnológico é um Força Básica ou Fundamental; o Contexto do Valor Percecionado, constitui-se numa Força Crítica para a adoção de inovação, que assenta na sua capacidade para oferecer valor aos diversos stakeholders da cadeia de cuidados. Temos também o Contexto Político, com capacidade de modelar a adoção da inovação e nomeadamente com capacidade para o acelerar, se dele emitir um sinal de urgência para a mudança. O Contexto Sociocultural e Individual expressam uma Força Intrínseca, dado que elas são características internas, próprias e imutáveis no curto-prazo, das sociedade e das pessoas. Por fim há que considerar o Contexto Específico da Doença, nesta caso o das demências. Das conclusões do estudo parece evidente que as condições tecnológicas estão medianamente satisfeitas em Portugal, com evidentes progressos nos últimos anos (exceção para a interoperabilidade aonde há necessidade de maiores progressos), não constituindo portanto barreira à introdução de ALT. Aonde há necessidade de investir é nas áreas do valor percebido. Da análise feita, esta é uma área que constitui uma barreira à introdução e adoção das ALT em Portugal. A falta de perceção do valor que estas tecnologias trazem, por parte dos profissionais de saúde, doentes, cuidadores e decisores políticos, parece ser o principal entrave à sua adoção. São recomendadas estratégias de modelos colaborativos de Investigação e Desenvolvimento e de abordagens de cocriação com a contribuição de todos os intervenientes na cadeia de cuidados. Há também um papel que cabe ao estado no âmbito das prioridades e da mobilização de recursos, sendo-lhe requerida a expressão do sentido de urgência para que esta mudança aconteça. Foram também identificadas oportunidades em diversas áreas, como na prevenção, no diagnóstico, na compliance medicamentosa, na terapêutica, na monitorização, no apoio à vida diária e na integração social. O que é necessário é que as soluções encontradas constituam respostas àquilo que são as verdadeiras necessidades dos intervenientes e não uma imposição tecnológica que só por si nada resolve. Do estudo resultou também a perceção de que há que (i) continuar a trabalhar no sentido de aproximar a comunidade científica, da clínica e do doente, (ii) fomentar a colaboração entre centros, com vista à criação de escala a nível global. Essa colaboração já parece acontecer a nível empresarial, tendo sido identificadas empresas Portuguesas com vocação global. A qualidade individual das instituições de ensino, dos centros de investigação, das empresas, permite criar as condições para que Portugal possa ser país um piloto e um case-study internacional em ALT, desde que para tal pudéssemos contar com um trabalho colaborativo entre instituições e com decisões políticas arrojadas.

The role of individual ability and structural embeddedness on entrepreneurial success

In the present thesis I analyse the roles of individual ability and structural embeddedness on entrepreneurial success. The results retrieved from a matched employer-employee longitudinal data set show prior worker productivities and environmental embeddedness to have a persistent positive impact on the size and growth rates of new firms. What is more, embeddedness facilitates the impact of ability on start-up performance with outsiders of comparable abilities starting smaller and slower growing firms. Those in higher ability categories are more likely to transfer and also, albeit to a lesser extent, close their ventures, an effect attributed to the higher opportunity costs associated with the group. Firms managed by embedded agents enjoy longer longevities and have better chances of finding a new owner after the departure of the previous one. Finally, higher ability types show evidence of specialisation in serial entrepreneurship.

The Change Questionnaire predicts change in hazardous tobacco and alcohol use.

INTRODUCTION: Assessing motivation for change is deemed an important step in the treatment process that allows further refinement of the intervention in motivational interviewing (MI) and brief MI (BMI) adaptations. During MI (and BMI) sessions, motivation for change is expressed by the client as "change talk", i.e. all statements inclined toward or away from change. We tested the predictive validity of the Change Questionnaire, a 12-item instrument assessing motivation to change, on hazardous tobacco and alcohol use. METHODS: As part of the baseline measurements for a randomized controlled trial on multi-substance BMI at the Lausanne recruitment center (army conscription is mandatory in Switzerland for males at age 20, and thus provides a unique opportunity to address a non-clinical and largely representative sample of young men), 213 participants completed the questionnaire on tobacco and 95 on alcohol and were followed-up six months later. The overall Change Questionnaire score and its six subscales (Desire, Ability, Reasons, Need, Commitment, and Taking steps) were used as predictors of hazardous tobacco use (defined as daily smoking) and hazardous alcohol use (defined as more than one occasion with six standard drinks or more per month, and/or more than 21 standard drinks per week) in bivariate logistic regression models at follow-up. RESULTS: Higher overall Change scores were significant predictors of decreased risk for hazardous tobacco (odds ratio [OR] = 0.83, p = 0.046) and alcohol (OR = 0.76, p = 0.03) use. Several sub-dimensions were associated with the outcomes in bivariate analyses. Using a principal components analysis to reduce the number of predictors for multivariate models, we obtained two components. 'Ability to change' was strongly related to change in hazardous tobacco use (OR = 0.54, p < 0.001), the second we interpreted as 'Other change language dimensions' and which was significantly related to change in hazardous alcohol use (OR = 0.81, p = 0.05). CONCLUSIONS: The present findings lend initial support for the predictive validity of the Change Questionnaire on hazardous tobacco and alcohol use, making it an interesting and potentially useful tool for assessing motivation to change among young males.
