Since the 1978 discovery of an islet “Oodaaq Island” north of Greenland, then considered to be the northernmost island in the world, multiple islets have been reported and apparently disappeared with regular intervals in the permanent sea ice-covered area offshore the northernmost part of Greenland. In this paper, we report results of comprehensive investigations at all quoted positions of reported islets, with bathymetry measurements, as well as supplementary lidar, ice thickness and gravity measurements during a helicopter reconnaissance. The bathymetry measurements confirm the non-existence of all the reported islets, and the northernmost land in the world is thus confirmed to be the moraine island “Inuit Qeqertaat” (Kaffeklubben Island) at latitude 83°39′54″ N, 30°37′45 ″ W. All reported islet positions are found at ocean depths from 26 m to 47 m, with no indications of shallow banks or submarine rocks at the reported positions. It is therefore concluded that all reported islets or new islands since 1978 have been stranded icebergs, likely originating from marine-terminating glaciers near Cape Morris Jesup, and stranded for up to several years in the relatively shallow and nearly permanently sea ice-covered areas around Inuit Qeqertaat.

We develop a model to perform a cost–benefit analysis of bus fare subsidies under financial constraints that preclude the purchase of additional buses. Our model considers users’ costs in the provision of bus services and the lack of road pricing to internalize urban transport externalities in a context where financial constraints severely limit the institutional ability to plan and design the bus system. Because of financial constraints, the bus system can hardly accommodate demand during peak times: buses travel overcrowded, passengers cannot board the first bus to arrive at the bus stop, and they cannot arrive at their destination at their desired time. Another salient aspect of our model is the inclusion of motorcycles as a second private transport mode. Motorcycles are typical in many urban agglomerations in the emerging world and engender many negative transport externalities. According to our results, fare subsidies provide social benefits in Metropolitan Asunción. During peak hours, a higher subsidy is justified as the reduction of the unpriced external costs of substitute modes compensates for the increased cost created by an additional bus passenger. In the off-peak, a higher subsidy is justified (i) as the higher frequencies induced by the new bus ridership reduce waiting times and (ii) because of the reduction of the unpriced external costs of substitute modes. Although our model does not explicitly include inequality aversion, we discuss the distributional aspects of subsidies in the context of middle-income countries.

Contaminated surfaces in clinics pose a pathogen transmission risk. Far ultraviolet-C light (UVC), with a favorable safety profile for human exposure, has the potential for continuous pathogen inactivation in occupied clinical areas. This study demonstrated real-world bioburden reduction on surfaces, despite frequent contamination from routine use by staff and patients in clinics.

Improvements to agricultural sustainability are required to maintain productivity in the face of ongoing global challenges, and growers need multiple kinds of support to adopt new sustainability practices and transform cropping systems. Farms are socio-ecological systems, and developing such systems requires tandem changes to human and nonhuman systems. This study evaluates agricultural sustainability practices and perception in the Oregon hazelnut industry, a small, intensified, and rapidly growing orchard production system in the United States. Using a mixed methods approach based on participant observation and an online survey of hazelnut growers in the spring of 2023, we found that growers were widely receptive to the sustainability messaging of industry groups and had widespread adoption of certain sustainability practices including disease-resistant tree varieties and changes in pesticide use, among other practices promoted by researchers. Larger hazelnut growers were more likely to adopt the sustainability practices in our survey, especially certain pest management practices. Growers with older hazelnut orchards turned to more sources of information but also perceived more barriers to implementing new sustainability practices than growers with younger orchards. Growers voiced different opinions about sustainability costs, with some growers expressing economic concerns about sustainability practices and others recognizing the financial benefits of sustainability practices. Differences in the perceived importance of short- and long-term benefits framed some of these concerns about the costs and benefits of sustainability practices. We argue that successful sustainability outreach will address both the short-term economic benefits of certain practices and the long-term sustainability benefits. Growers widely recognize the importance of sustainability, but more messaging about the multiple benefits of sustainability practices can better address both environmental and economic concerns.

Is Christ hypostatically united to his human nature during Holy Saturday? If so, how, given that he is (in effect) an object whose parts are in different ‘places’? In this article, I argue that God the Son does indeed remain hypostatically united to his human nature during Holy Saturday and that this is salvifically salient. One way to construe this ongoing union through somatic death is by means of the analogy of a ‘dead limb’ – Christ’s human body being that limb. I set out several ways of making sense of this claim consistent with a broadly orthodox account of the hypostatic union as a contribution to the theology of Holy Saturday and the intermediate state more broadly.

Trust is essential for effective collaboration. In advice settings, decision-makers’ trust in their advisors determines their willingness to follow advice. We propose that trust in the opposite direction, that is, the trust of the advisor in the decision-maker, can affect the use of advice. Specifically, we suggest that advice-taking is greater after a show of trust by the advisor than after an instance of distrust. We conducted four behavioral experiments using the trust game and judge–advisor system paradigms and one scenario study using a sample of currently employed professionals (N = 1599). We find that initial displays of trust by advisors result in greater acceptance of their advice (Studies 1A-B). This effect persists across different levels of advice quality, resulting in smaller underutilization of high-quality advice but also in overreliance on low-quality advice (Study 2). Decision-makers not only show greater willingness to follow advisors who trust them but also respond similarly to advisors who display trust in other people (Study 3). Finally, we find evidence for both perceived advisor competence and decision-makers’ motivation to reciprocate as mediators of the relation between advisors’ level of trust and decision-makers’ willingness to follow their advice (Study 4). Our findings shed light on the dynamics of trust and persuasion in advice relationships and provide insight for advisors who wish to maintain the effectiveness of their input.

The comparative literature has devoted considerable attention to why individuals join political parties. This is especially important in the context of the declining party membership and activism that political parties face in contemporary politics. While the question of why members join parties has been well-documented, considerably less work has considered incentives to join other party positions. In the Canadian case, for example, we know very little about the incentives to join an electoral district association (EDA). This is surprising given the consequential role—both formal and informal—that local party associations and their presidents have been known to play in intra-party politics (influencing candidate nomination, membership recruitment and so forth). This study applies Clark and Wilson's (1961) framework of material, solidary and purposive incentives to local party association membership and asks why individuals join their local party executive and whether this motivation shapes the subsequent character of the EDA.

Why is solidarity between people of color (PoC) so difficult to achieve? New evidence suggests solidarity can be activated through a sense of shared discrimination between PoC. Yet other research highlights many real-world obstacles to this solidarity, including recurring inter-minority conflicts. We consider system justification as one possible mechanism that undercuts PoC solidarity. System justification is a human motive to bolster the status quo. System justifiers who are PoC condone racial inequalities as stable, predictable, and just—which alleviates mental stressors associated with their own racially stigmatized status. We investigate system justification’s impacts on Asian Americans: a key party to many coalitions and conflicts with Black and Latino people. Using national survey data, we find that system justification is significantly associated with Asian opposition to solidarity with Black Lives Matter, net of racial resentment, and other key covariates. We then refine this result experimentally by exposing Asian adults to the model minority myth—a system-legitimizing ideology. Exposure to this myth triggers system justification, which then increases Asian opposition to pro-Black and pro-Latino policies, among other solidarity-based outcomes. Both results are primarily driven by conservative Asian Americans, highlighting a need to better appreciate Asian Americans’ ideological diversity in U.S. racial politics.
