    agile - exploitation - ideation - large firms - organizational learning

    Originally developed for software development, Agile approaches are increasingly adopted by organizations that seek flexibility in the face of rapid change. However, little attention has been paid to the potential negative consequences of the implementation of Agile in large-scale settings. This article presents the results of a multi-site study of a multinational telecom company over five years during its implementation of Agile practices in the context of large-scale software development. The article points to six potential pitfalls of implementing such practices that may negatively influence individual learning, ideation, and exploitation capabilities. It offers advice on how to avoid these consequences in large, established firms.

    Australian Journal of Rural Health 28 (2020)4. - ISSN 1038-5282 - p. 338 - 350.
    Objectives - To advance the rural practice in working with Aboriginal communities by (a) identifying the extent of community partners' participation in and (b) operationalising the key elements of three community‐based participatory research partnerships between university‐based researchers and Australian rural Aboriginal communities.
    Design - A mixed‐methods study. Quantitative survey and qualitative one‐on‐one interviews with local project implementation committee members and group interviews with other community partners and project documentation.
    Setting - Three rural Aboriginal communities in New South Wales.
    Participants - Thirty‐seven community partners in three community‐based participatory research partnerships of which 22 were members of local project implementation committees and 15 were other community partners who implemented activities
    Intervention - Community‐based participatory research partnerships to develop, implement and evaluate community‐based responses to alcohol‐related harms.
    Main outcomes measures - Community partners' extent of and experiences with participation in the community‐based participatory research partnership and their involvement in the development and implementation processes.
    Results - Community partners' participation varied between communities and between project phases within communities. Contributing to the community‐based participatory research partnerships were four key elements of the participatory process: unique expertise of researchers and community‐based partners, openness to learn from each other, trust and community leadership.
    Conclusion - To advance the research practice in rural Aboriginal communities, equitable partnerships between Aboriginal community and research partners are encouraged to embrace the unique expertise of the partners, encourage co‐learning and implement community leadership to build trust

    A Janus-faced food industry? : ethical reflections on corporate responsibility for health
    Tempels, Tjidde - \ 2019
    Wageningen University. Promotor(en): M.F. Verweij, co-promotor(en): V. Blok. - Wageningen : Wageningen University - ISBN 9789463951456 - 168

    Food-related non-communicable diseases (NCDs) such as obesity, type 2 diabetes and cardiovascular diseases are key threats to public health. Yet, the responsibility for food-related health harms is contested. While traditionally viewed as mainly an individual responsibility or a governmental responsibility, fingers are nowadays also pointed at the food and beverage industry, as many firms are producing and marketing unhealthy products that contribute to the rise of obesity and other food-related NCDs. Yet, does the behaviour of the industry and the impact its products have on public health also give reason for moral concern? Are these firms doing anything wrong? Are there normative considerations on the basis of which it can be argued that food and beverage firms have a responsibility for public health?

    This thesis explores the moral grounds for firms in the food and beverage industry to address food-related public health problems, and simultaneously reflects upon what taking responsibility for these problems could entail in practice.

    Drawing on debates in business ethics, political philosophy, and public health ethics, it is argued that food and beverage firms have distinct responsibilities for food-related health problems, and that these responsibilities spring from considerations of non-maleficence, respect for autonomy and justice.

    The thesis makes clear how responsibility for public health can be understood as an essentially shared responsibility, and outlines what taking responsibility could entail for various firms in the food and beverage industry (e.g. healthy innovation, pro-health marketing, and political lobbying for a level playing field) and makes recommendations on what kind of behaviour firms should no longer engage in (e.g. marketing unhealthy products to children and teenagers and lobbying against public health regulation).

    Growth in world population will inevitably leads to increased demand for protein for humans and animals. Protein from insects and blood plasma are being considered as possible alternatives, but more research on their nutritional quality and health effects is needed. Here, we studied the effect of dietary protein source on metabolism and metabolic amine profiles in serum and urine of mice. Groups of mice were fed semi-purified diets containing 300 g/kg of soybean meal, casein, partially delactosed whey powder, spray-dried plasma
    protein, wheat gluten meal, and yellow mealworm. Feed and water intake as well as body weight gain were measured for 28 days. After 14 and 28 days, serum and urine samples were collected for measurement of a large panel of amine metabolites. MetaboAnalyst 3.0 was used for analysis of the raw metabolic data. Out of 68 targeted amine metabolites, we could detect 54 in urine and 41 in blood serum. Dietary protein sources were found to have profound effects on host metabolism, particularly in systemic amine profiles, considered here as an endophenotype. We recommend serum over urine to screen for the amine metabolic endophenotype based on partial least squares discriminant analysis. We concluded that metabolites like alpha-aminobutyric acid and methylhistidine are sensitive indicators of too much or too little availability of specific amino acids in the different protein diets. Furthermore, we concluded that amine metabolic profiles can be useful for assessing the nutritional quality of different protein sources.

    fecal microbiota transplantation - insulin sensitivity - intestinal microbiota composition - plasma metabolites

    The intestinal microbiota has been implicated in insulin resistance, although evidence regarding causality in humans is scarce. We therefore studied the effect of lean donor (allogenic) versus own (autologous) fecal microbiota transplantation (FMT) to male recipients with the metabolic syndrome. Whereas we did not observe metabolic changes at 18 weeks after FMT, insulin sensitivity at 6 weeks after allogenic FMT was significantly improved, accompanied by altered microbiota composition. We also observed changes in plasma metabolites such as γ-aminobutyric acid and show that metabolic response upon allogenic FMT (defined as improved insulin sensitivity 6 weeks after FMT) is dependent on decreased fecal microbial diversity at baseline. In conclusion, the beneficial effects of lean donor FMT on glucose metabolism are associated with changes in intestinal microbiota and plasma metabolites and can be predicted based on baseline fecal microbiota composition. Kootte et al. show that fecal microbiota transplantation from lean donors to obese patients with metabolic syndrome improves insulin sensitivity, a transient effect associated with changes in microbiota composition and fasting plasma metabolites. Baseline fecal microbiota composition in recipients predicts the response to lean donor fecal microbiota transplantation.

    16S rRNA genes - Amplicon sequencing - Anaerobic digestion - McrA genes - Plant secondary metabolites

    Coumarins are widely found in plants as natural constituents having antimicrobial activity. When considering plants that are rich in coumarins for biogas production, adverse effects on microorganisms driving the anaerobic digestion process are expected. Furthermore, coumarin derivatives, like warfarin, which are used as anticoagulating medicines, are found in wastewater, affecting its treatment. Coumarin, the structure common to all coumarins, inhibits the anaerobic digestion process. However, the details of this inhibition are still elusive. Here, we studied the impact of coumarin on acetogenesis and methanogenesis. First, coumarin was applied at four concentrations between 0.25 and 1 g · liter-1 to pure cultures of the methanogens Methanosarcina barkeri and Methanospirillum hungatei, which resulted in up to 25% less methane production. Acetate production of syntrophic propionate- and butyrate-degrading cultures of Syntrophobacter fumaroxidans and Syntrophomonas wolfei was inhibited by 72% at a coumarin concentration of 1 g · liter-1. Coumarin also inhibited acetogenesis and acetoclastic methanogenesis in a complex biogas reactor microbiome. When a coumarin-adapted microbiome was used, acetogenesis and methanogenesis were not inhibited. According to amplicon sequencing of bacterial 16S rRNA genes and mcrA genes, the communities of the two microbiomes were similar, although Methanoculleus was more abundant and Methanobacterium less abundant in the coumarin-adapted than in the nonadapted microbiome. Our results suggest that well-dosed feeding with coumarin-rich feedstocks to full-scale biogas reactors while keeping the coumarin concentrations below 0.5 g · liter-1 will allow adaptation to coumarins by structural and functional community reorganization and coumarin degradation.

    Are there ethical differences between stopping and not starting blood safety measures?

    Cost-effectiveness - Donor blood safety - Ethics - Transfusion-transmissible infections - Withdrawing vs. withholding
    Background and Objectives: Concern with the costs of blood safety is growing, which raises the question whether safety measures that reduce risk only marginally should be discontinued. Withdrawing such safety measures would allow reallocating resources to more efficient health care interventions, but it might raise moral objections. Materials and Methods: This study evaluates two ethical arguments why discontinuing blood safety measures would be more objectionable than not implementing them. The first argument is that whereas withdrawing protective measures causes harm to patients, not starting protective measures 'merely' omits to prevent harm. The second argument is that patients who benefit from protective measures are historically entitled to the continuation of those protective measures. Results: Both arguments are unconvincing. There is only a weak causal connection between removing blood safety measures and harms that transfusion recipients suffer. Moreover, patients are not entitled to the continuation of protective measures that prove very inefficient, unless applying these protective measures rectifies past injustice towards them. Conclusion: Unless stronger ethical objections can be found, blood system operators and regulators should be more willing to withdraw inefficient safety measures.
    Actief antirookbeleid is morele taak van overheid; Verantwoordelijkheid voor minder roken ligt bij individu én maatschappij

    Tobacco discouragement, smoking cessation and tobacco endgame policies are sometimes criticised for being unduly paternalistic: governments should respect citizens' freedom and not take over their individual responsibility for healthy behaviour. In this commentary, I argue that very strict tobacco policies can be justified on multiple grounds, including the harm principle, the public good of maintaining a healthy society, and the reduction of health inequities. The moral reasons governments have to protect people against the harms of smoking do not limit or infringe upon the responsibility of each individual to take care of her own health: responsibility for healthy behaviour is not a zero-sum game.

    The Precautionary Principle and the Tolerability of Blood Transfusion Risks

    donor blood safety - MSM and blood donation - opportunity costs - precautionary principle - risk - risk-based decision-making - transfusion-transmissible infections
    Tolerance for blood transfusion risks is very low, as evidenced by the implementation of expensive blood tests and the rejection of gay men as blood donors. Is this low risk tolerance supported by the precautionary principle, as defenders of such policies claim? We discuss three constraints on applying (any version of) the precautionary principle and show that respecting these implies tolerating certain risks. Consistency means that the precautionary principle cannot prescribe precautions that it must simultaneously forbid taking, considering the harms they might cause. Avoiding counterproductivity requires rejecting precautions that cause more harm than they prevent. Proportionality forbids taking precautions that are more harmful than adequate alternatives. When applying these constraints, we argue, attention should not be restricted to harms that are human caused or that affect human health or the environment. Tolerating transfusion risks can be justified if available precautions have serious side effects, such as high social or economic costs.
    Identifying Environmental and Human Factors Associated With Tick Bites using Volunteered Reports and Frequent Pattern Mining

    Tick populations and tick-borne diseases like Lyme borreliosis have been steadily increasing since the mid-1990s. Realizing the threat that ticks pose to public health, two Dutch citizen science projects have collected tick bite reports since 2006. This unique volunteered geographical dataset, which currently has nearly 35,000 reports, was used to identify environmental and other circumstantial factors associated with tick bites. For this, we first enriched the tick bite reports with temperature, precipitation, vegetation and volunteered data associated with the location of the tick bite. Using this enriched dataset, we then derived a series of features to characterize the environmental and volunteer-related conditions in which each tick bite occurred. Next, we discretized these features using the Jenks Natural Breaks algorithm and, after that, we mined frequent environmental patterns associated with tick bites using the AprioriClose algorithm. Finally, we checked that these patterns are specifically associated with the tick bites by comparing them with the frequent patterns mined from pseudo-random locations. The frequent patterns were visualized using heat maps and ring maps and two representative patterns associated with tick bites were projected into geographic space to study their spatio-temporal distribution. Our results show that factors linked to human activity are more relevant to model tick bites than seasonal accumulations of temperature, vegetation or precipitation. In particular, the number of warm and dry days per season are present in a significant number of patterns and the majority of tick bites are produced within a distance of half a kilometer of a forest, recreational or built-up area. The study of patterns in the time-series revealed that there are several persistent patterns consistently occurring each year and the validation process showed that the volunteer tick bites collection is capturing environmental conditions associated with tick bites, suggesting that these reports have a high scientific value. These results support the creation of a Dutch tick bite risk map that, in turn, will open the door to the design of public health interventions to reduce the incidence of Lyme disease.

    Not everyone dealing with agricultural issues in Malawi appreciates the fact that smallholders in this country face challenges which are unique in Africa. No other country in Sub-Saharan Africa has population densities of up to 250 to the square km combined with a single rainy season of five months. The five areas with comparable population densities to those of Malawi have rain all the year or have two rainy seasons. Their smallholders can grow perennial food crops and, on a small piece of land, establish high value perennial cash crops such as tea, coffee and vanilla. On the other hand farmers living in areas with comparable rainfall to Malawi occupy comparatively thinly populated countries and so are able to grow larger areas of food crops to meet their needs and larger areas of low value annual cash crops such as cotton and legumes and so raise some cash for their family requirements. Many Malawian smallholders can adopt neither of these options. The overwhelming majority cannot grow coffee or tea because of inadequate rainfall and the limitations of small farm size means that they can only produce small amounts of any crop other than their basic staples. About 15% grow burley tobacco but that number cannot be increased as the crop is already over-produced. A further 10% raise cash from rice, groundnuts, maize and horticultural crops but the great majority have to allocate all of their land to producing food for the family and rely on low paid casual occupations to raise the cash that they need. It is for this reason that the majority of rural Malawians are classified as being below the poverty line. An appreciation of this situation can help in an understanding of the current state of smallholder farming in Malawi and it is hoped that these notes may cast a little more light on the plight of this country’s millions of small scale farmers and provide some indicators as to how best they can be helped.

    Nationwide surveys have shown a threefold increase in general practitioner (GP) consultations for tick bites and early Lyme borreliosis from 1994 to 2009 in the Netherlands. We now report an update on 2014, with identical methods as for the preceding GP surveys.

    To all GPs in the Netherlands, a postal questionnaire was sent inquiring about the number of consultations for tick bites and erythema migrans diagnoses (most common manifestation of early Lyme borreliosis) in 2014, and the size of their practice populations.

    Contrasting to the previously rising incidence of consultations for tick bites between 1994 and 2009, the incidence decreased in 2014 to 488 consultations for tick bites per 100,000 inhabitants, i.e., 82,000 patients nationwide. This survey revealed a first sign of stabilization of the previously rising trend in GP diagnosed erythema migrans, with 140 diagnoses per 100,000 inhabitants of the Netherlands. This equals about 23,500 annual diagnoses of erythema migrans nationwide in 2014.

    In contrast to the constantly rising incidence of GP consultations for tick bites and erythema migrans diagnoses in the Netherlands between 1994 and 2009, the current survey of 2014 showed a first sign of stabilization of erythema migrans diagnoses and a decreased incidence for tick bite consultations. een webplatform voor wetenschappelijk onderzoek naar tekenbeten en de ziekte van Lyme

    Decades of population genetic research reveal the need for harmonization of molecular markers : The grey wolf Canis lupus as a case study

    Collaboration - Genetic monitoring - Recommendations - Reference collection - Transnational research

    Following protection measures implemented since the 1970s, large carnivores are currently increasing in number and returning to areas from which they were absent for decades or even centuries. Monitoring programmes for these species rely extensively on non-invasive sampling and genotyping. However, attempts to connect results of such studies at larger spatial or temporal scales often suffer from the incompatibility of genetic markers implemented by researchers in different laboratories. This is particularly critical for long-distance dispersers, revealing the need for harmonized monitoring schemes that would enable the understanding of gene flow and dispersal dynamics. Based on a review of genetic studies on grey wolves Canis lupus from Europe, we provide an overview of the genetic markers currently in use, and identify opportunities and hurdles for studies based on continent-scale datasets. Our results highlight an urgent need for harmonization of methods to enable transnational research based on data that have already been collected, and to allow these data to be linked to material collected in the future. We suggest timely standardization of newly developed genotyping approaches, and propose that action is directed towards the establishment of shared single nucleotide polymorphism panels, next-generation sequencing of microsatellites, a common reference sample collection and an online database for data exchange. Enhanced cooperation among genetic researchers dealing with large carnivores in consortia would facilitate streamlining of methods, their faster and wider adoption, and production of results at the large spatial scales that ultimately matter for the conservation of these charismatic species.
