tract Micro wind turbines can be structurally integrated on top of the solid base of noise barriers near highways. A number of performance factors were assessed with holistic experiments in wind tunnel and in the field. The wind turbines underperformed when exposed in yawed flow conditions. The theoretical cosθ theories for yaw misalignment did not always predict power correctly. Inverter losses turned out to be crucial especially in standby mode. Combination of standby losses with yawed flow losses and low wind speed regime may even result in a net power consuming turbine. The micro wind turbine control system for maintaining optimal power production underperformed in the field when comparing tip speed ratios and performance coefficients with the values recorded in the wind tunnel. The turbine was idling between 20%–30% of time as it was assessed for sites with annual average wind speeds of three to five meters per second without any power production. Finally, the field test analysis showed that inadequate yaw response could potentially lead to 18% of the losses, the inverter related losses to 8%, and control related losses to 33%. The totalized loss led to a 48% efficiency drop when compared with the ideal power production measured before the inverter. Micro wind turbine’s performance has room for optimization for application in turbulent wind conditions on top of noise barriers. https://doi.org/10.3390/en14051288

Empirical studies in the creative arts therapies (CATs; i.e., art therapy, dance/movement therapy, drama therapy, music therapy, psychodrama, and poetry/bibliotherapy) have grown rapidly in the last 10 years, documenting their positive impact on a wide range of psychological and physiological outcomes (e.g., stress, trauma, depression, anxiety, and pain). However, it remains unclear how and why the CATs have positive effects, and which therapeutic factors account for these changes. Research that specifically focuses on the therapeutic factors and/or mechanisms of change in CATs is only beginning to emerge. To gain more insight into how and why the CATs influence outcomes, we conducted a scoping review (Nstudies = 67) to pinpoint therapeutic factors specific to each CATs discipline, joint factors of CATs, and more generic common factors across all psychotherapy approaches. This review therefore provides an overview of empirical CATs studies dealing with therapeutic factors and/or mechanisms of change, and a detailed analysis of these therapeutic factors which are grouped into domains. A framework of 19 domains of CATs therapeutic factors is proposed, of which the three domains are composed solely of factors unique to the CATs: “embodiment,” “concretization,” and “symbolism and metaphors.” The terminology used in change process research is clarified, and the implications for future research, clinical practice, and CATs education are discussed.

In early game development phases game designers adjust game rules in a rapid, iterative and flexible way. In later phases, when software prototypes are available, play testing provides more detailed feedback about player experience. More often than not, the realized and the intended gameplay emerging from game software differ. Unfortunately, adjusting it is hard because designers lack a means for efficiently defining, fine-tuning and balancing game mechanics. The language Machinations provides a graphical notation for expressing the rules of game economies that fits with a designer's understanding and vocabulary, but is limited to design itself. Micro-Machinations (MM) formalizes the meaning of core language elements of Machinations enabling reasoning about alternative behaviors and assessing quality, making it also suitable for software development. We propose an approach for designing, embedding and adapting game mechanics iteratively in game software, and demonstrate how the game mechanics and the gameplay of a tower defense game can be easily changed and promptly play tested. The approach shows that MM enables the adaptability needed to reduce design iteration times, consequently increasing opportunities for quality improvements and reuse.

Though there are different interpretations in the scholarly literature of what a social learning is: whether it is an individual, organisational, or collective process. For example, Freeman (2007), in his study on policy change in the public health sector, conceptualised collective learning of public officials as a process of epistemological bricolage. In his interpretation, the new policy ideas are the result of this bricolage process, when the “acquired second-hand” ideas are transformed into “something new”. The literature on (democratic) governance points opens another perspective to the policy change, emphasising the importance of public engagement in the policy-making process. Following this school of thought the new policy is the result of a deliberative act that involves different participants. In other words, the ideas about policy are not borrowed, but are born in social deliberation. Combining the insights gained from both literatures – social learning and governance – the policy change is interpreted, as a result of a broad social interaction process, which is also the social learning for all participants.The paper will focus on further development of the conceptualisation of policy change through social deliberation and social learning and will attempt to define the involved micro mechanisms. The exploratory case study of policy change that was preceded by a broad public debate will help to describe and establish the mechanisms. Specifically, the paper will focus on the decision of the Dutch government to cease the exploration of natural gas from the Groningen gas field. The radical change in national policy regarding gas exploration is seen as a result of a broader public debate, which was an act of social deliberation and social learning at the same time.

Introduction: In March 2014, the New South Wales (NSW) Government (Australia) announced the NSW Integrated Care Strategy. In response, a family-centred, population-based, integrated care initiative for vulnerable families and their children in Sydney, Australia was developed. The initiative was called Healthy Homes and Neighbourhoods. A realist translational social epidemiology programme of research and collaborative design is at the foundation of its evaluation. Theory and Method: The UK Medical Research Council (MRC) Framework for evaluating complex health interventions was adapted. This has four components, namely 1) development, 2) feasibility/piloting, 3) evaluation and 4) implementation. We adapted the Framework to include: critical realist, theory driven, and continuous improvement approaches. The modified Framework underpins this research and evaluation protocol for Healthy Homes and Neighbourhoods. Discussion: The NSW Health Monitoring and Evaluation Framework did not make provisions for assessment of the programme layers of context, or the effect of programme mechanism at each level. We therefore developed a multilevel approach that uses mixed-method research to examine not only outcomes, but also what is working for whom and why.

People want to participate and not remain on the side-lines. Most people have good ideas for how to participate, but making those ideas a reality requires money, as well as knowledge, information and an enabling environment. There are, in fact, people amongst the lesser fortunate in society who want to be able to borrow money, take out insurance, transfer money and set aside money as savings at affordable prices and ideally as close as possible. An increasing number of people seized such opportunities empowered by microfinance. Today, a network of microfinance institutions is providing all kinds of services in many countries, ranging from micro loans (microcredit), micro insurance, micro savings to micro pensions. All of those services are offered in a way different to that which banks were used to. A new way of handling money and bringing people and finance together has developed. A network of new organisations has emerged that has gained attention. The success of microcredit has been given the attention it deserved, yet microfinance is now facing criticism. Does the money reach the right people? Why are the interest rates so high? Who actually benefits from it? Why are private investors interested to join? And why are microfinance organisations once set up with clear, social goals sold to private parties on the market? The question is rightly tabled whether financial inclusion is still being pursued. In order to contribute to that discussion, one needs to know what microcredit or microfinance actually is all about. What do we understand by these terms?

Purpose - This paper provides an overview on the technical and vocational education and training (TVET) program components/mechanisms and their overall effect on learning outcomes in a developing country context. Design/methodology/approach - Using secondary data, this descriptive case study integrates the realistic evaluation framework of Pawson and Tilley (1997) with Total Quality Management (TQM) frameworks. Findings - Ethiopia's TVET system adopts/adapts international best practices. Following the implementation of the 2008 TVET strategy, the proportion of formal TVET graduates who were recognized as competent by the assessment and certification system increased from 17.42 percent in 2009/2010 to 40.23 percent in 2011/2012. Nevertheless, there is regional variation. Research limitations/implications - Outcome-based TVET reforms that are based on TQM frameworks could improve learning outcome achievements in developing countries by enhancing awareness, coordination, integration, flexibility, participation, empowerment, accountability and a quality culture. Nevertheless, this research is limited by lack of longitudinal data on competency test results. There is also a need for further investigation into the practice of TQM and the sources of differences in internal effectiveness across TVET institutions. Practical implications - Our description of the Ethiopian reform experience, which is based on international best experience, could better inform policy makers and practitioners in TVETelsewhere in Africa. Originality/value - A realistic evaluation of TVET programs, the articulation of the mechanisms, especially based on TQM, that affect TVET effectiveness would add some insight into the literature. The evidence we have provided from the Ethiopian case is also fresh.

Why is it that we know and still act as if we do not know? SMEs are considered engines of job creation and therefore growth and generation of income but is it really true that the solo self-employed and micro entrepreneurs will become small or medium entrepreneurs, e.g. graduate? We knew in the 80’s that this assumption needed to be looked at critically. Research revealed that graduation hardly existed. Practitioners in MSME support and development programmes entertain few illusions about their programmes actually leading to graduation, while NGO and Government policy officers, from behind their desks, often presume that graduation occurs frequently. Actual graduation rates and the extent to which they can be attributed to interventions remain an unresolved and important issue. After more than three decades it is justified to the question whether it is still true that graduation hardly exists? If that is the case one needs to take a critical look into prevailing policies and programs in support of the SME sector.

The ‘precision’ in Precision Livestock Farming is not the same as that of precision engineering in high-tech industry. It’s not about micro- and nanometers, but about the precise control of farming management with the aid of sensing and data processing. However, there is overlap in the technological domain, for instance regarding sensors and robots. So, both worlds can learn from each other. That’s why in Den Bosch, mechanical engineering students pursuing a minor in ‘Machines in Motion’ are working on a farming application. Mikroniek offers a sneak preview.

Thermal disinfection is probably the oldest water treatment method ever used. Similarly to other disinfection processes, it targets the inactivation of pathogenic (micro)organisms present in water, wastewater and other media. In this work, a pilot-scale continuous-flow thermal disinfection system was investigated using highly contaminated hospital wastewater as influent without any pre-treatment step for turbidity removal. The results proved that the tested system can be used with influent turbidity as high as 100 NTU and still provide up to log 8 microbial inactivation. Further results have shown energy consumption comparable to other commercially available thermal disinfection systems and relatively low influence on the investigated physical–chemical parameters.
