The mixed impact of design thinking on business collaborations

The present work project investigates the implications of design thinking on an interbusiness collaborative project, unveiling both the benefits and fragilities that derive from the use of such methodology within the mentioned context. The study is organized in two parts. The first one starts with a literature review on the two relevant frames of reference – design thinking and business collaboration. It proceeds to the creation of a conceptual framework to assess the potential value of the design-based approach. The second part focuses on the practical application of to the newly developed instrument to the inTRAIN project – R&D for railway interiors.

Shared lives social impact bond feasibility study

Loneliness and isolation among the elderly is an enormous problem in Portugal. Interventions to tackle loneliness worldwide have had limited success, and new approaches are needed. Shared Lives is an adult foster placement service in the UK that shows significant promise in tackling both loneliness, isolation and other societal challenges linked with ageing. This feasibility study suggests that replicating a Shared Lives service in Portugal, using a Social Impact Bond (SIB), is viable and likely to create both social and financial value for all stakeholders involved. This study provides recommendations for how a Shared Lives SIB could be designed and implemented.

A doença pulmonar obstrutiva crónica e o exercício: impacto da doença no declínio funcional e importância do treino de exercício nos benefícios para a saúde

RESUMO: A reabilitação respiratória (RR) é uma intervenção abrangente e interdisciplinar dirigida aos doentes respiratórios crónicos e inclui o treino de exercício, programas de educação e de modificação comportamental, entre outros, desenhados individualmente para melhorar o desempenho físico e psicossocial e promover a adesão a longo prazo a comportamentos promotores de saúde. A doença pulmonar obstrutiva crónica (DPOC) é uma doença comum, afetando cerca de 210 milhões de pessoas em todo o mundo, com elevada mortalidade e com custos económicos significativos decorrentes do agravamento progressivo da doença, das hospitalizações e de reinternamentos frequentes. Apesar do crescente conhecimento da DPOC e do papel da RR nos benefícios para a saúde, existem aspetos ainda não esclarecidos que têm impacto na prática clínica e de investigação e nas decisões das autoridades de saúde. A primeira parte desta tese focou a DPOC e o seu impacto negativo e incluiu: o estudo da prevalência da DPOC em Portugal; os fatores clínicos e funcionais que se associam à mortalidade em doentes com DPOC avançada; a morbilidade, impacto funcional e risco dos doentes se tornarem dependentes para as atividades diárias e a influência da inflamação sistémica. A prevalência estimada da DPOC de 14,2% indica que esta é uma doença comum em Portugal e alerta para a necessidade de uma maior sensibilização da população, dos profissionais de saúde e autoridades de saúde com vista a um diagnóstico precoce e à alocação dos recursos terapêuticos adequados. A elevada taxa de mortalidade em doentes com DPOC avançada - 36,6% em 3 anos - associou-se a insuficiência respiratória, a elevado número de exacerbações, ao cancro do pulmão e a reduzida capacidade funcional para a marcha, salientando a importância da referenciação precoce para RR, a identificação e o tratamento das comorbilidades e a prevenção das exacerbações. A aplicação de um questionário que avaliou as atividades da vida diária básicas e instrumentais, permitiu identificar um marcador clínico do risco de dependência, complementando as avaliações funcionais e associando-se a outros marcadores de mau prognóstico, como as exacerbações. Em doentes com DPOC, com FEV1 médio de 46,76% (desvio padrão: 20,90%), 67% da categoria D do GOLD, verificou-se uma associação positiva entre a expressão de genes inflamatórios avaliada pela reação em cadeia da polimerase (ARN mensageiro de IFNg, IL1b, IL6, IL8, TNFa, TGFb1, iNOS) e o índice de massa corporal em repouso, acentuando-se após o exercício. Este estudo aponta a inflamação como o potencial elo de ligação entre a obesidade e a inflamação sistémica em doentes com DPOC. A segunda parte da tese focou a RR, nomeadamente os seus efeitos em doentes das categorias GOLD A, B, C e D; o impacto das comorbilidades nos resultados da RR e os resultados de diferentes intensidades de treino aeróbio. Após o programa de RR, verificaram-se melhorias significativas na capacidade de exercício funcional e de endurance e no estado geral de saúde dos doentes de todas as categorias GOLD. Esta classificação não distingue os doentes que melhor poderão beneficiar desta intervenção, indicando que devem ser referenciados para RR, os doentes sintomáticos ou com repercussão na qualidade de vida, independentemente da categoria da DPOC a que pertençam. A prevalência das comorbilidades no grupo de doentes com DPOC que é referenciado para RR, é elevada, sendo as mais frequentes, as cardiovasculares, as respiratórias e as psicológicas. Apesar de poderem diminuir o impacto da RR, os resultados desta foram semelhantes independentemente do número de comorbilidades. A identificação e o tratamento sistemáticos das comorbilidades conferem maior segurança clínica a esta intervenção terapêutica a qual, por apresentar bons resultados, não deve limitar a referenciação dos doentes. Com o programa de RR, verificou-se melhoria significativa em todos os resultados centrados no doente para ambas as intensidades de treino aeróbio, a 60% e a 80% da potência aeróbica máxima (Wmax), com melhoria do estado geral de saúde, nos sintomas e na capacidade para o exercício, o que questiona a indicação sistemática de elevadas intensidades de treino em doentes com DPOC para a obtenção de benefícios a curto prazo. Na terceira e última parte da tese foi estudado o papel da atividade física na DPOC, focando os fatores que influenciam a atividade física diária; a evolução da capacidade funcional e o estado de saúde 2 anos após um programa de RR e o papel da telemonitorização na quantificação e monitorização da atividade física. Confirmámos que os doentes com DPOC são marcadamente sedentários e os fatores que se associaram ao sedentarismo nestes doentes foram a dispneia e a distância percorrida na prova de marcha de seis minutos. Este estudo sublinha a importância do controlo sintomático, nomeadamente da dispneia, bem como, mais uma vez, o potencial papel da reabilitação respiratória no aumento da capacidade funcional para o exercício e na aquisição de hábitos de vida fisicamente ativa. Verificámos que, apesar de os doentes com DPOC apresentarem benefícios clinicamente significativos na capacidade funcional para o exercício e no estado geral de saúde com o programa de RR, apenas os que se mantêm ativos, podem, no final dos dois anos de seguimento, manter os efeitos benéficos desse programa. O sistema de telemonitorização que combina a oximetria e a quantificação da atividade física provou ser clinicamente útil na avaliação da necessidade de oxigenoterapia de longa duração (OLD) e na aferição do débito de oxigénio em repouso, no esforço e no sono, podendo contribuir para uma melhor adequação da prescrição da OLD. A monitorização dos níveis de atividade física regular é um importante instrumento de avaliação dos programas de RR e o seu uso potencial na telereabilitação permitirá prolongar a eficácia dos programas e reduzir os custos associados aos cuidados de saúde.---------------------------------------------------------------------------------------------------ABSTRACT: Pulmonary rehabilitation (PR) is a comprehensive interdisciplinary intervention that includes, but is not limited to, exercise training, education, and behavior change, individually designed to improve physical and psychological conditions of people with chronic respiratory disease and to promote long-term adherence to health-enhancing behaviors. Chronic obstructive pulmonary disease (COPD) is a common disease, affecting about 210 million people worldwide, with high mortality and significant health-related costs due to disease progression, hospitalizations and frequent hospital readmissions. Although the increasing knowledge about COPD and benefitial outcomes of PR, some aspects with impact in clinical practice, research and health authorities’ decisions, remain to be clarified. The first part of this thesis focused on COPD and its negative impact, including the study of COPD prevalence in Portugal; clinical and functional factors associated with mortality in advanced COPD patients; morbidity, functional impact and risk of others’ dependance to perform activities of daily living; and the role of systemic inflammation. The evidence of 14.2% estimated COPD prevalence as a common disease in Portugal raises the need of an increasing awareness of population, health care professionals and health authorities towards an earlier diagnosis and apropriate treatment resources allocation. High mortality in patients with advanced COPD – 36.6% in 3 years - was associated with respiratory failure, high frequency of exacerbations, lung cancer and a low functional capacity in walking. This highlightens the importance of an earlier referral to PR, comorbidity identification and treatment, and prevention of exacerbations. A questionnaire evaluated basic and instrumental activities of daily living, and identified a clinical marker of the risk of becoming dependent. This clinical marker complemented other functional evaluations and was associated with prognosis markers such as the number of exacerbations. In COPD patients with a mean FEV1 46.76% (SD 20.90%), 67% belonging to GOLD grade D, we found a positive association between inflammatory gene expression evaluated by polymerase chain reaction (IFNg, IL1b, IL6, IL8, TNFa, TGFb1, iNOS RNA messenger) and body mass index at rest, and a further increase with exercise. This study evidenced obesity as one potential link between COPD and systemic inflammation. The second part of this thesis focused PR, namely its outcomes in patients of GOLD categories A, B, C and D; comorbidities impact in PR outcomes, and the impact of different exercise training intensities in patient related outcomes. xviii With PR intervention, we found significant improvement in functional exercise capacity, endurance exercise capacity and health status in patients of all GOLD categories. This classification did not differentiate which patients would benefit more from PR, hence all symptomatic patients with a negative impact in health status should be referred to PR, regardless of the GOLD category they belong to. There is a high prevalence of comorbidities in COPD patients referred to PR, being cardiovascular, respiratory and psychological, the most prevalent. Although some comorbidities might reduce PR impact, the results were similar regardless of the number of comorbidities. Systematic comorbidities identification and treatment provides safety to PR intervention, and its good results should not preclude patients referral. With PR intervention we found a significant improvement in all patient reported outcomes for exercise training intensities at 60% and 80% maximum work rate (Wmax), namely in health status, symptoms and exercise capacity. These findings challenge the current systematic indication of high exercise training intensities to achieve PR short-term benefits. In the third and last part of the thesis, the role of physical activity in COPD was studied, focusing factors that may influence daily physical activity; the evolution of functional capacity and health status two years after a PR program, and the role of a telemonitoring system in physical activity quantification and monitoring. We confirmed that COPD patients are markedly inactive and factors associated with a sedentary lifestyle are dyspnea and 6 minute walking distance. This study emphasized the importance of symptom control, namely of dyspnea, as well as, once again, the potential role of PR in functional exercise improvement and in integrating physically active habits in daily life. We verified that, although COPD patients improve functional exercise capacity and health status after a PR program, only those who kept physical activity habits were able to maintain those effects after 2 years of follow-up. A telemonitoring system that combines oximetry and physical activity quantification proved to be clinically useful in the evaluation of long-term oxygen therapy (LTOT) indication, as well as in the titration of oxygen levels at rest, exertion, and sleeping, which might contribute to a more adequate LTOT prescription. Monitoring of daily physical activity levels is an important PR evaluation instrument and its potential use in telerehabilitation might allow lengthening programs efficacy, while reducing health-care costs.

How could marketing automation impact the business performance of Comexposium?

Comexposium continues to exhibit strong growth through global acquisition of key events. However, the company identified the need to increase the renewal rate of its exhibitors. In order to do so, Comexposium determined marketing automation software could have enormous value. However, the company currently does not have the appropriate data to determine to specific returns the software could provide. Thus, this report focused on assessing the impact of marketing automation on the business performance of a B2B enterprise and the best methods to implement and measure it. The main findings were that the software could be of immense value to Comexposium, if the company is ready to invest in internal resources and take the time to adapt to the changes the tool will incur.

Understanding impact readiness in Portugal’s social sector and designing a framework for capacity-building for social impact

This project is based on the theme of capacity-building in social organisations to improve their impact readiness, which is the predictability of delivering intended outcomes. All organisations which have a social mission, non-profit or for-profit, will be considered to fall within the social sector for the purpose of this work. The thesis will look at (i) what is impact readiness and what are the considerations for building impact readiness in social organisations, (ii) what is the international benchmark in measuring and building impact readiness, (iii) understand the impact readiness of Portuguese social organisations and the supply of capacity building for social impact in Portugal currently, and (iv) provide recommendations on the design of a framework for capacity building for impact readiness adapted to the Portuguese context. This work is of particular relevance to the Social Investment Laboratory, which is a sponsor of this project, in its policy work as part of the Portuguese Social Investment Taskforce (the “Taskforce”). This in turn will inform its contribution to the set-up of Portugal Inovação Social, a wholesaler catalyst entity of social innovation and social investment in the country, launched in early 2015. Whilst the output of this work will be set a recommendations for wider application for capacity-building programmes in Portugal, Portugal Inovação Social will also clearly have a role in coordinating the efforts of market players – foundations, corporations, public sector and social organisations – in implementing these recommendations. In addition, the findings of this report could have relevance to other countries seeking to design capacity building frameworks in their local markets and to any impact-driven organisations with an interest in enhancing the delivery of impact within their work.

The impact of poor power quality in solar photovoltaic microgeneration: technical problems and losses of revenue

This paper presents a critical and quantitative analysis of the influence of the Power Quality in grid connected solar photovoltaic microgeneration installations. First are introduced the main regulations and legislation related with the solar photovoltaic microgeneration, in Portugal and Europe. Next are presented Power Quality monitoring results obtained from two residential solar photovoltaic installations located in the north of Portugal, and is explained how the Power Quality events affect the operation of these installations. Afterwards, it is described a methodology to estimate the energy production losses and the impact in the revenue caused by the abnormal operation of the electrical installation. This is done by comparing the amount of energy that was injected into the power grid with the theoretical value of energy that could be injected in normal conditions. The performed analysis shows that Power Quality severally affects the solar photovoltaic installations operation. The losses of revenue in the two monitored installations M1 and M2 are estimated in about 27% and 22%, respectively.

Equity offerings, stock price crash risk, and the impact of securities regulation: international evidence

We examine whether earnings manipulation around seasoned equity offerings (SEOs) is associated with an increase in the likelihood of a stock price crash post-issue and test whether the enactment of securities regulations attenuate the relation between SEOs and crash risk. Empirical evidence documents that managerial tendency to conceal bad news increases the likelihood of a stock price crash (Jin and Myers, 2006; Hutton, Marcus, and Tehranian, 2009). We test this hypothesis using a sample of firms from 29 EU countries that enacted the Market Abuse Directive (MAD). Consistent with our hypothesis, we find that equity issuers that engage in earnings management experience a significant increase in crash risk post-SEO relative to control groups of non-issuers; this effect is stronger for equity issuers with poor information environments. In addition, our findings show a significant decline in crash risk post-issue after the enactment of MAD that is stronger for firms that actively manage earnings. This decline in post-issue crash risk is more effective in countries with high ex-ante institutional quality and enforcement. These results suggest that the implementation of MAD helps to mitigate managers’ ability to manipulate earnings around SEOs.

The impact of PBL on transferable skills development in management education

Attention to transferable skills is growing in higher education. Problem-based learning (PBL) is increasingly used in management education for its promising potential to, amongst others, promote transferable skills, including problem-solving, critical thinking and teamwork skills. However, this relationship is seldom assessed. In this study, I use structural equation modelling to examine the effectiveness of PBL, measured through students’ perceptions of satisfaction and skills development. Results show the development of transferable skills is explained by interaction with tutors and a host company, and defining teamwork rules. Satisfaction is explained by skills development, assessment issues, defining teamwork rules and understanding how organisations work. I draw conclusions and recommendations.

On the impact of overlapping access points in detecting node encounters

Data traces, consisting of logs about the use of mobile and wireless networks, have been used to study the statistics of encounters between mobile nodes, in an attempt to predict the performance of opportunistic networks. Understanding the role and potential of mobile devices as relaying nodes in message dissemination and delivery depends on the knowledge about patterns and number of encounters among nodes. Data traces about the use of WiFi networks are widely available and can be used to extract large datasets of encounters between nodes. However, these logs only capture indirect encounters between nodes, and the resulting encounters datasets might not realistically represent the spatial and temporal behaviour of nodes. This paper addresses the impact of overlapping between the coverage areas of different Access Points of WiFi networks in extracting encounters datasets from the usage logs. Simulation and real-world experimental results show that indirect encounter traces extracted directly from these logs strongly underestimate the opportunities for direct node-to- node message exchange in opportunistic networks.

Impact of an occupational gym program on flexibility in office workers

The problem of work-related musculoskeletal disorders is a rising concern in the companies. Thus, occupational gym has emerged as a possible solution to this problem because it leads to changes in the lifestyle by promoting health and physical activity. In this regard, this study purposes to evaluate the impact of an occupational gym program in the neck and shoulder flexibility in office workers. In order to evaluate the levels of flexibility, a universal goniometer was used for pre and post occupational gym program implementation. The program had an extension of three months, with 15 minutes sessions twice a week. The sample consisted in an intervention group comprised of 30 elements and a control group composed of 8 elements. The results suggest that there were improvements in flexibility at the cervical spine and shoulder segments levels. The increase on flexibility between the two time points in the intervention group was significant, unlike the control group that presented only slight improvements.

The impact of work clothing design on workers’ comfort

Physical and physiological comfort, at work and during leisure time, is important to human health and motivation. A growing number of jobs require workers to sit. Most clothes, except those intended for wheelchair users, were designed for walking or the standing position. Clothing designs should be user-oriented and meet users’ needs. Garment design should conform to body position and posture, not just shape and size. In this paper we present the ergometric impact of a new type of trousers designed to adapt to changes in position. Concentrations of compression forces, temperature and pressure were documented in an exploratory pilot study and contrasted to traditional designs. The new trousers showed significant decreases in compression force concentration, especially in and around the knees and waist. Most participants identified comfort as an important factor when purchasing a pair of trousers and that, for working purposes, they would prefer these special trousers rather than traditional designs.

Mitigating the impact of occupational noise exposure for elderly workers: Setting the functional requirements for an ANC system

Noise affects people in very different aspects and in almost every aspect of our daily life. The most prominent impact of noise exposure is hearing loss. However, it can also impair people at their work settings due to other effects rather than hearing loss. Older works tend to be more susceptible to noise exposure effects at work, firstly because most of them already have some ‘natural’ hearing loss, as a results of the ageing process, and secondly because they also tend to be more susceptible at an psychological level. The current study is an attempt to describe the potential problem and to make a survey to identify the available active noise cancelation systems, as well as to specific the main requirements of this type of systems to be applied in such contexts. Several aspects of characteristics of the ANC systems were identified and are presented in this study. From the obtained results it was possible to have a clearer idea about the potential of this technology, and to confirm that this type of solution can be extremely important as a component of an active ageing program, as the preservation of hearing will also impact on the social life of the exposed workers.
