Show moreThis book examines the issuance of mining licenses in Indonesia from an environmental perspective. It shows how mining licensing has directly contributed to environmental degradation and how consecutive governments have failed to take effective action addressing this problem. The main cause is the low quality of the relevant laws and policies, which is mostly a result of the priority law- and policymakers accord to mining development and a lack of interest in and knowledge about solving environmental problems. This situation has been exacerbated by a lack of public participation and bureaucratic “siloism”: government agencies often develop their own policies and regulations without efforts at co-ordination with other relevant government agencies. Only in a few cases have there been better results, when government agencies developing a policy had a strong interest in its implementation, when their officials disposed of adequate expertise, and when there was a favourable national political situation. Unfortunately, these conditions have rarely been present in Indonesia. Show less

Show moreThe application of nanomaterials in industrial processes and consumer products provides many societal benefits, but can also lead to the release of nanomaterials into the environment. The work in this dissertation aims to provide insights into the potential environmental impacts that may follow from this, with specific reference to populations and communities of freshwater invertebrates. Based on experimental studies conducted under conditions reflecting those in natural ecosystems, this dissertation shows that commonly applied methodological approaches can lead to an underestimation of the long-term impacts of nanomaterials on freshwater organisms, particularly at the level of populations and communities. In doing so, this dissertation provides perspective on the role of relevance and realism in ecotoxicological assessments, and shows that impact assessments at higher ecological levels can provide sensitive and reliable insights that can serve as a basis for regulation, and guide the development of safer and more sustainable chemicals, substances and materials.

Show moreInnovation plays an essential role in firms' competitiveness and long-term success. It varies from different types, ranging from run-of-the-mill innovation that brings incremental changes to existing technologies to radical innovation that breaks from existing trajectories. The aim of this PhD dissertation is to integrate radical innovation and social network literature to broaden theoretical understanding, especially contribute to the literature on social networks, creativity, and innovation, and inform innovation management by unpacking the drivers and effects of radical innovation. Focusing on the long-standing debates in the social network literature regarding which types of networks are more advantageous for innovation, this dissertation starts with investigating how tie strength and structural holes collectively affect innovation radicalness at a location within an innovating firm. Then this dissertation investigates how social structure for producing a creative idea influences the adoption and future use of its innovations and makes a novel contribution by exploring how this effect is contingent on the radical nature of the creative idea. In addition to contributing to this long-standing debate, this dissertation also investigates how radicalness affects the private value for the innovating firm. Show less

Show moreThis research investigates tensions associated with positive organizational change (POC) that prioritizes strengths-based dialogue over talk about organizational problems or deficits (Fitzgerald et al., 2010) by bridging the concept of organizational shadow (Bowles, 1991; Fitzgerald et al., 2010; Jung, 1968) with dialectical tension theory (Baxter & Simon, 1993). A recent flurry of studies suggests toxic positivity results in the marginalizing of individuals for expressing their emotions that may not always be positive (Collins, 2022; Cross, 2022; Tufvesson, 2020). A key question this research addresses is what do with the "elephants in the room" that represent what people think is undiscussable in a POC context? Interviews with 41 organizational development practitioners, with more than 600 cumulative years of experience leading POC initiatives using the Appreciative Inquiry (AI) methodology, identified the contexts in which tensions are likely to arise, the theoretical implications of tensions, and practical strategies to navigate tensions in a POC context. This study’s findings advance scholarship on positive organizing by naming the voice, leadership, and temporal shadows. These shadows emerge as three dialectical tensions: free expression and limited expression of what is discussible in the change process, hierarchical and collaborative leadership, and short-term orientation versus long-term orientation. The results of this study demonstrate experienced POC practitioners navigate tensions underlying the voice, leadership, and temporal shadows by using nuanced strategies, such as creating space to hear divergent perspectives, coaching leaders to demonstrate agility in support of collaborative initiatives, and reframing tension such that one pole does not negate the other.

Show moreThis dissertation showed that physicians must be aware of the constraints that allow them to identify or obviate (un)desirable effects most notably if they evaluate these effects in a blinded matter. Unblinding might partially mitigate the limitation, but current measurement methods have gaps that we should remain aware of. Detailed measurements of subintervals with characterization of ion channel profiles, concentration QTc modelling, or machine learning might help physicians in their decision making in the future.

Show moreAI-powered emotion recognition, typing with thoughts or eavesdropping virtual assistants: three non-fictional examples illustrate how AI may impact society. AI-related products and services increasingly find their way into daily life. Are the EU's fundamental rights to privacy and data protection equipped to protect individuals effectively? In addressing this question, the dissertation concludes that no new legal framework is needed. Instead, adjustments are required. First, the extent of adjustments depends on the AI discipline. There is nothing like 'the AI'. AI covers various concepts, including the disciplines machine learning, natural language processing, computer vision, affective computing and automated reasoning. Second, the extent of adjustments depends on the type of legal problem: legal provisions are violated (type 1), cannot be enforced (type 2) or are not fit for purpose (type 3). Type 2 and 3 problems require either adjustments of current provisions or new judicial interpretations. Two instruments might be helpful for more effective legislation: rebuttable presumptions and reversal of proof. In some cases, the solution is technical, not legal. Research in AI should solve reasoning deficiencies in AI systems and their lack of common sense. Show less

Less is known about their role within the legal system. Meanwhile, interest groups are the driving force behind many high-profile lawsuits against the Dutch government, such as the lawsuits concerning climate change, the quality of asylum facilities, and the Dutch nitrogen policy. This research focuses on the access of interest groups to the courts. How extensive is their access? Does it threaten or protect a democratic society under the rule of law? The access of interest groups to Dutch administrative and civil courts is evaluated in terms of legitimacy and effectiveness. Since interest group litigation is at the intersection of politics and law, the research adopts an interdisciplinary approach. Beyond the boundaries of Dutch legal scholarship, it seeks insights from social sciences regarding the role of interest groups within the political decision-making process. Additionally, it examines, from a legal sociological perspective, the role that interest groups play in public interest litigation in the United States. As a result, the research explores approaches, concepts, and arguments that have largely remained outside of the Dutch legal legal discourse. Ultimately, this leads to a reassessment of both the legitimacy and effectiveness of interest groups' access to the courts. Show less

We call this community the infant gut microbiota. The microbiota influences the health of the infant, which makes the composition and function of the infant gut microbiota an important topic to study. It’s not possible to directly study the development of the microbiota inside the infant, so we are limited to information from fecal samples and laboratory experiments. Because it is so difficult to study, the processes and mechanisms that shape the microbiota also remain unclear. Mathematical models can generate hypotheses and predictions about the unseen inner workings of a system such as the infant gut microbiota.In this thesis we develop a mathematical model that makes predictions both on how bacteria are influenced by the environment and on how they influence the environment. By applying this influence to the environment and repeating the technique, the model can make predictions for how the whole system changes over time. We use this model to make predictions on how changes to the environment, such as the presence of oxygen, antibiotic disturbances, or in particular the presence of oligosaccharides, influence the infant gut microbiota, their metabolism, and ultimately the infant.

Show moreThis editorial serves as an introduction to Media and Communication’s thematic issue Policy Framing and Branding in Times of Constant Crisis. Crises cast challenges for political actors and concurrently create opportunities for policymaking, public reflections, and political competition. In times of crisis, when it comes to communicating policymaking but also framing the crisis itself, issues close to political communication (including political marketing and political branding) become of paramount relevance. The eight articles of this issue cover a broad array of subjects, expanding the understanding of the relevance of communication when it comes to policymaking in times of crisis, through the lens of policy framing and policy branding.

Show moreBackground: Knowledge of the psychosocial impact of facial skin surgery on patients can help improve counselling strategies.Objectives: The objective was to measure the psychological impact of facial skin cancer surgery on patients over a 1-year period. Secondary objective was to meas-ure the difference between Mohs micrographic surgery (MMS) and conventional excision (CE) on these parameters.Methods: This observational survey study was conducted between March 2019 and July 2020. Patients who had facial skin surgery using MMS or CE were selected. Five surveys were conducted on four timepoints (preoperative, 1 week, 3 months and 1 year post-operative) measuring the quality of life, perceived stigmatization, body image, satisfaction with facial appearance and psychosocial distress.Results: A total of 228 patients (MMS 154 patients, CE 74 patients) were included for the analysis. Scores for quality of life did not significantly change, in the year after surgery (PCS-12 mean 50.5, SD 9.3 and MCS-12 50.6, SD 9.4); however, stigmatiza-tion (F (3, 235,39) 7,26, p < 0.01, d = −0.07), body image concerns (F (3, 198,28) = 3.75, p < 0.01, d = −0.14), satisfaction with facial appearance (F (3, 205,18) = 10.74, p < 0.01, d = 0.43) and psychosocial distress (F (3, 208,69) = 9.26, p < 0.01, d = −0.15) did change over time. The use of MMS or CE did not significantly affect outcome scores after 1 year.Conclusion: Patients receiving facial skin cancer surgery exhibited low scores for perceived stigmatization and body image concerns. Their quality of life was not statistically inf luenced by facial surgery, and their satisfaction with their facial appearance and psychosocial distress even improved after 1 year. The results suggest that the surgical treatment type (MMS or CE) does not inf luence the outcome. The overall results can help in counselling strategies to improve expectations for patients receiving facial surgery. Show less

Show moreUntil the 17th century, the Dutch coastal region of Zeeland ranked among Europe's most urbanized areas, driven by thriving international trade networks. People living in this time of flourishing economy benefitted enormously from it in terms of employment opportunities and working conditions, which were reportedly better than in the rest of the Low Countries. However, the rapid growth of Zeeland's urban centers likely presented increasing challenges for the population in terms of accessing essential resources, including food, clean water, and housing. In the 19th century, Zeeland's economy ultimately faced a significant downturn due to the decline in the maritime trade, leading to a substantial reduction in its urban population. Examining patterns of urbanization and economic histories that differ from the commonly studied thriving industrial contexts in bioarcheological research, as exemplified by Zeeland, is a crucial yet relatively underexplored facet in our efforts to understanding the human past. To address this gap, this study investigates the impact of urbanization on the health of Zeeland's inhabitants over time by analyzing nonspecific stress markers (i.e., cribra orbitalia, porotic hyperostosis, and linear enamel hypoplasia) and chronic maxillary sinusitis in a sample of 246 individuals from three urban sites dating from 1030 to 1800 CE. Our analysis of skeletal remains reveals significant differences in the prevalence of porotic hyperostosis, linear enamel hypoplasia, and sinusitis between the medieval and post-medieval periods. These findings suggest that de-urbanization and economic decline adversely affected the health and well-being of the populations under study, influenced by factors such as working conditions and food availability. This study provides a new perspective on bioarcheological approaches to urbanization, shedding light on the intricate realities of urbanization in Zeeland and offering important insights into its complexities.

Show moreChemokine receptors are relevant targets for a multitude of immunological diseases, but drug attrition for these receptors is remarkably high. While many drug discovery programs have been pursued, most prospective drugs failed in the follow-up studies due to clinical inefficacy, and hence there is a clear need for alternative approaches. Allosteric modulators of receptor function represent an excellent opportunity for novel drugs, as they modulate receptor activation in a controlled manner and display increased selectivity, and their pharmacological profile can be insurmountable. Here, we discuss allosteric ligands and their pharmacological characterization for modulation of chemokine receptors. Ligands are included if (1) they show clear signs of allosteric modulation in vitro and (2) display evidence of binding in a topologically distinct manner compared to endogenous chemokines. We discuss how allosteric ligands affect binding of orthosteric (endogenous) ligands in terms of affinity as well as binding kinetics in radioligand binding assays. Moreover, their effects on signaling events in functional assays and how their binding site can be elucidated are specified. We substantiate this with examples of published allosteric ligands targeting chemokine receptors and hypothetical graphs of pharmacological behavior. This review should serve as an effective starting point for setting up assays for characterizing allosteric ligands to develop safer and more efficacious drugs for chemokine receptors and, ultimately, other G protein-coupled receptors.

Show moreThis thesis describes a set of excitability measurements -transcranial magnetic stimulation (TMS) combined with electromyography (EMG) and electroencephalography (EEG), nerve excitability threshold tracking (NETT), and muscle velocity recovery cycles (MVRC)- and the applicability of these tools in early phase clinical drug development. We validated the biomarkers in healthy subjects with registered drugs and showed that the measurements are all repeatable and sensitive to pharmacological effects, even in a small number of subjects. Furthermore, we have evaluated effects of a novel AMPA-positive allosteric modulator with TMS-EMG/EEG, and a first-in-class skeletal muscle-specific chloride channel (ClC-1) inhibitor with MVRC, and the findings helped us to confirm proof-of-mechanism of these compounds in healthy subjects. In conclusion, these measurements proved to be valuable pharmacodynamic biomarkers in two drug development programs, encouraging their further use in clinical development of other future drug candidates targeting cortical-, neuronal-, and muscle cell excitability. The use of such clinical pharmacodynamic biomarkers could improve the quality and efficiency of the development process of drugs for e.g. amyotrophic lateral sclerosis, chronic pain, depression, treatment-resistant epilepsy, and neuromuscular diseases.

Show moreThe healthcare landscape is constantly evolving. eHealth (electronic health) presents opportunities to alleviate pressure in healthcare, for example by empowering patients to take more control over their care. This thesis has examined various digital applications that have already been (partially) implemented. The research primarily focuses on the user-friendliness and effectiveness of these digital applications, aiming to promote self-management and accessibility of healthcare. The digital applications in this thesis relate to requesting diagnostic tests, both with and without involvement of healthcare professionals. Diagnostic tests enable the detection of conditions, such as sexually transmitted diseases for instance. Additionally, research has been conducted on the effectiveness of a self-management program for asthma and COPD. The results generally indicate that patients and citizens, particularly the younger generation, are receptive to online applications aimed at supporting their self-management of health and illness. Nevertheless, certain factors influence their acceptance, such as reliability and user-friendliness. Therefore, it is essential to promote collaboration among all stakeholders to enhance usability and ensure that online applications effectively meet their intended purpose and objectives. Show less

Show moreFor decades, public health experts and journalists worldwide warned about a viral pandemic capable of causing illness and loss of life. Previous outbreaks of SARS, Ebola, and MERS highlighted this threat, which occupied top positions in risk assessments globally. Yet even with knowledge and precedent, the COVID-19 pandemic caught the world off guard. It revealed a world inadequately prepared and plunged societies into a state of disruption, with over 7 million deaths reported to the World Health Organization by April 2024. How did this tragedy foretold take the world by such surprise? In The COVID-19 Intelligence Failure: Why Warning Was Not Enough, Erik J. Dahl explores this question from the vantage point of the United States.In his book, Dahl, who is highly regarded for his expertise on intelligence failures, analyzes past and present intelligence efforts to underline the shortcomings and successes of the U.S. intelligence community's anticipation of the pandemic, comparing the anticipation and response to COVID-19 with historical failed warnings, such as those preceding 9/11 and Pearl Harbor.
