Abstract The paper focuses on minor metals and coupled elements and aspires to understand individual incidents of imbalance on the mineral markets during the last 100 years and gain insight into the acting dynamics—those dynamics are commodity-specific but remain largely unchanged in their nature to date—and to identify the factors in play. The conclusions allow for a critical analysis of the widespread security-of-supply narrative of industrialized countries. They point at a market that is mostly a buyers’ market, in which prices and their volatility are largely dictated by shifting demand patterns and much less by supply constraints. Neither high country concentration nor poor governance seem to have a substantial or lasting impact on market balance. Short-term market imbalances are generally neutralized by a dynamic reaction on the demand side via substitution, efficiency gains or technological change. The paper also assesses the impact of those quickly shifting demand patterns and the related price volatilities on producing countries. It shows how mineral price volatilities can expose developing countries’ economies to significant economic risk, if their economy is heavily dependent on mineral production. Two cases that illustrate country exposure are explored in detail—the saltpeter crisis in Chile and the tin crisis in Bolivia. Both led to state bankruptcy. The paper concludes with an attempt to quantify economic exposure of producing countries to price volatilities of specific metals and suggests policies that adapt to the characteristic challenges of highly volatile demand.

Abstract Background As in many countries, quantifying COVID-19 spread in Indonesia remains challenging due to testing limitations. In Java, non-pharmaceutical interventions (NPIs) were implemented throughout 2020. However, as a vaccination campaign launches, cases and deaths are rising across the island. Methods We used modelling to explore the extent to which data on burials in Jakarta using strict COVID-19 protocols (C19P) provide additional insight into the transmissibility of the disease, epidemic trajectory, and the impact of NPIs. We assess how implementation of NPIs in early 2021 will shape the epidemic during the period of likely vaccine rollout. Results C19P burial data in Jakarta suggest a death toll approximately 3.3 times higher than reported. Transmission estimates using these data suggest earlier, larger, and more sustained impact of NPIs. Measures to reduce sub-national spread, particularly during Ramadan, substantially mitigated spread to more vulnerable rural areas. Given current trajectory, daily cases and deaths are likely to increase in most regions as the vaccine is rolled out. Transmission may peak in early 2021 in Jakarta if current levels of control are maintained. However, relaxation of control measures is likely to lead to a subsequent resurgence in the absence of an effective vaccination campaign. Conclusions Syndromic measures of mortality provide a more complete picture of COVID-19 severity upon which to base decision-making. The high potential impact of the vaccine in Java is attributable to reductions in transmission to date and dependent on these being maintained. Increases in control in the relatively short-term will likely yield large, synergistic increases in vaccine impact.

The full capabilities of well-structured project management are rarely realized outside of the scope of the respective profession. The tools and skills in which project managers specialize are furthermore often considered in high-level business contexts, but are far less remembered as crucial components to many other endeavors. This project portfolio serves as an insight into the structure and process of managing a short-term social awareness project and an exploration and application of various project management tools. It also provides a review of the success of implementing sound project management toward humanitarian work on a community level. Public Equity, the team of university students behind this project and report, ultimately hopes to inspire others to learn how they may increase the impact of their community work through strong planning and goal setting.

Switzerland is considering implementing a strategic energy reserve, a novel policy instrument that remunerates power plant operators for storing a minimum amount of energy in reservoirs to convert into electricity when called upon. The policy is envisioned for the winter period, when the country’s large hydropower reservoirs tend to be nearly depleted. This study analyzes the impact of such a strategic energy reserve on security of supply, consumer costs, international trade, and sustainability. A hybrid simulation model is developed that combines agent-based modeling and system dynamics. The simulations show that the reserve can improve short-term security of supply but does not improve long-term security of supply as it does not impact domestic investments or reduce the import dependency in winter. The reserve leads to a slight increase in consumer costs, even when including the reduction in outage costs. A larger reserve is more effective at reducing the supply risk but is proportionally costly. Lastly, we find that the policy induces scarcity periods that would not have occurred otherwise, which means that the reserve should have a high strike price to ensure it is only called upon as a last resort. We conclude that there is no structural need for a strategic energy reserve, as it only increases short-term security of supply and does not contribute to solving the structural problem. Any implementation should be done on an ad hoc basis, conditional on a short-term generation adequacy assessment. This has the potential to minimize the associated costs while maximizing the benefits.

The significant ideological and cultural role of public museums in shaping national identity is widely acknowledged. This paper focuses on the roles of Taiwan’s public art museums in generating nationalist narratives that privilege notions of cultural distinctiveness and authenticity in the visual representation of art from Taiwan. Two exhibitions of contemporary Indigenous art provide a platform for critical analysis of the impact of identity politics on the selection, display, and promotion of Taiwanese Indigenous art. Questions of artistic agency are also explored in this paper, demonstrating how Indigenous artists in Taiwan are increasingly interrogating and contesting systems of museological representation which seek to locate or “frame” Indigenous art within an Austronesian nationalist identity narrative. These exhibitions and the artists’ works and observations offer an insight into the complex and shifting interrelationship between national identity politics and the museological representation of art in Taiwan.

Over the past few decades technology has become ubiquitous, with technology companies gaining increasing insight into the lives of individuals. This paper explores how technology companies use these insights to influence the ability to exercise free and independent decision-making. Through a critical analysis of social nudging, I establish the subtle but significant ways in which individuals can be susceptible to manipulation. Through this lens, I highlight some notable examples of how big tech companies have manipulated individual decision-making and the impact this may have on our democracy.

AbstractThe apparent early success in China’s large-scale intervention to control the COVID-19 epidemic has led to interest in whether other countries can replicate it as well as concerns about a resurgence of the epidemic if or when China relaxes the interventions. In this paper we look at the impact of a single short-term intervention on an epidemic. We see that if an intervention cannot be sustained long-term, it has the greatest impact if it is imposed once infection levels have become large enough that there is an appreciable number of infections present. For minimising the total number infected it should start close to the peak so that there is no rebound once the intervention is stopped, while to minimise the peak prevalence, it should start earlier, allowing two peaks of comparable size rather than one very large peak. In populations with distinct subgroups, synchronized interventions are less effective than targeting the interventions in each sub-population separately.We do not attempt to clearly determine what makes an intervention sustainable or not. We believe that is a policy question. If an intervention is sustainable, it should be kept in place. Our intent is to offer insight into how best to time an intervention whose impact on society is too great to maintain.

Abstract. Folk wisdom tells us that additional time to make a decision helps us to refrain from the first impulse to take the bird in the hand. However, the question why the time to decide plays an important role is still unanswered. Here we distinguish two explanations, one based on a bias in value accumulation that has to be overcome with time, the other based on cognitive control processes that need time to set in. In an intertemporal decision task, we use mouse tracking to study participants’ responses to options’ values and delays which were presented sequentially. We find that the information about options’ delays does indeed lead to an immediate bias that is controlled afterwards, matching the prediction of control processes needed to counter initial impulses. Hence, by using a dynamic measure, we provide insight into the processes underlying short-term oriented choices in intertemporal decision making.
