The wine industry, considered to be male-dominated, has seen a growing share of women winemakers. Using a randomized online experiment, we investigate how the producer’s gender influences consumers’ willingness to pay for the wine. Gender can be identified either from the first name of the producer or from a gendered group of wine producers. Using a Tobit and a double-hurdle model, our results suggest that consumers’ willingness to pay is lower for wine produced by female winemaker groups. This reduction appears to be particularly pronounced when the consumer is male.

Some products, notably but not only platforms, increase in value for users as the number of other users increases. These interaction or network effects can result in ‘product market traps’ (Bursztyn et al., 2023) where people who use the product would be better off if they all stopped using it and switched to another product, but cannot because of coordination problems. A parallel but overlooked phenomenon is the labor market trap, where employees would be better off if they collectively left an employer, job, or profession, but cannot because of the difficulty of coordination. Product market and labor market traps pose a challenge to public policy because of the complexity of people’s behavior in networks, but can be mitigated in some cases with relatively simple taxes and regulatory interventions.

Chaque année, les Instituts de recherche en santé du Canada (IRSC) subventionnent le Programme d’été sur le vieillissement (PEV). Cette année, la semaine de formation qui rassemblait des étudiants canadiens de tous les cycles supérieurs avait pour thème la recherche multidisciplinaire au quatrième âge. Cette note de recherche présente trois éléments de réflexion de deux participants de l’édition 2023 du PEV : 1) les enjeux liés au vieillissement sont des occasions de transformer les paradigmes de la recherche; 2) la recherche collaborative doit être sociétale, et s’étendre au-delà du cercle restreint des milieux universitaires; 3) les critères d’équité, de diversité et d’inclusion intégrés aux projets de recherche doivent se refléter au sein des organisations qui mènent la recherche.

Biophysical conditions played a fundamental role in early human colonization of insular territories, particularly in food-producing societies dealing with limited resources and the challenges of maintaining a sustainable carrying capacity. Studies on past human colonization of small oceanic islands thus offer insights into economic plasticity, ecological impacts, and adaptation of early food-producing groups. On the coast of southern Chile, early evidence is dated to 950 cal BP of island colonization by coastal populations with mainland subsistence systems based on the exploitation of marine resources, along with gathering, managing, and cultivating plants and hunting terrestrial animals. Strikingly, the extent to which these mixed economies contributed to insular colonization efforts is largely unknown. Here we used organic residue analysis of ceramic artifacts to shed light on the subsistence of populations on Mocha Island in southern Chile. We extracted and analyzed lipids from 51 pottery sherds associated with the El Vergel cultural complex that flourished in southern Chile between 950 and 400 cal BP. Chemical and stable isotope analysis of the extracts identified a range of food products, including C3 and C4 plants and marine organisms. The results reveal the central role of mixed subsistence systems in fueling the colonization of Mocha Island.

A multi-shot target assembly and automatic alignment procedure for laser–plasma proton acceleration at high repetition rate are introduced. The assembly is based on a multi-target rotating wheel capable of hosting more than 5000 targets, mounted on a 3D motorized stage to allow rapid replenishment and alignment of the target material between laser irradiations. The automatic alignment procedure consists of a detailed mapping of the impact positions at the target surface prior to the irradiation that ensures stable operation of the target, which alongside the purpose-built design of the target wheel, enables operation at rates up to 10 Hz. Stable and continuous laser-driven proton acceleration at 10 Hz is demonstrated, with observed cut-off energy stability about 15%.

Despite the shock provoked by the Snowden revelations, mass surveillance is still a reality in the EU. However, over the past few years, it has been possible to observe a gradual constitutionalization of these practices. This Article maps the ongoing process of progressively defining the constitutional limits and societal affordances of mass surveillance in the EU by focusing on the three main actors who contribute to it. First, this Article presents civil society as the propeller of this trend. Civil society not only advocated for a ban on general surveillance systems in the aftermath of the Snowden revelations, but also promoted a series of strategic litigations to challenge state surveillance practices at national and EU levels. Second, it analyses CJEU case law as the main constitutionalizing engine of this process. The Court pragmatically ascertained that an absolute prohibition of mass surveillance did not appear to be a realistic solution and put significant effort into actively defining the legal boundaries of these practices by striving to find an equilibrium between Member State interests and citizens’ fundamental rights. Third, it considers the approaches taken by national legislators to be a slowing factor. States are still reluctant to incorporate the constitutional standards progressively developed by courts despite the now significant body of judicially created parameters in the field.

A new magnetic mirror machine named KAIMIR (KAIST mirror) has been designed and constructed at the Korea Advanced Institute of Science and Technology (KAIST) to study mirror plasma physics and simulate the boundary regions of magnetic fusion plasmas such as in a tokamak. The purpose of this paper is to introduce the characteristics and initial experimental results of KAIMIR. The cylindrical vacuum chamber has a length of 2.48 m and a diameter of 0.5 m and consists of three sub-chambers, namely the source, centre and expander chambers. A magnetic mirror configuration is achieved by electromagnetic coils with a maximum magnetic field strength of 0.4 T at the mirror nozzles and 0.1 T at the centre. The source plasma is generated by a plasma washer gun installed in the source chamber with a pulse forming network system. The typical discharge time is ~12 ms with a ~6 ms (1–7 ms) steady period. Initial results show that the on-axis electron density at the centre is 1019–20 m−3 and the electron temperature is 4–7 eV. Two parameters were varied in this initial phase, the source power and the mirror ratio, which is the ratio of highest to lowest magnetic field strength in the mirror-confined region. We observed that the increase of the electron density was mitigated for a source power above 0.2 MW. It was also found that the electron density increases almost linearly with the mirror ratio. Accordingly, the stored electron energy was also linearly proportional to the mirror ratio, similar to the scaling of the gas dynamic trap.

In this paper we take up the classical sup-norm problem for automorphic forms and view it from a new angle. Given a twist minimal automorphic representation $\pi$ we consider a special small $\mathrm{GL}_2(\mathbb{Z}_p)$-type V in $\pi$ and prove global sup-norm bounds for an average over an orthonormal basis of V. We achieve a non-trivial saving when the dimension of V grows.

This study uses anonymized GPS traces to explore travel patterns within six suburban zones and a central area in Mexico City. The descriptive analysis presented in this paper profiles trips by distance and investigates their distribution within each zone. It examines the prevalence of local trips, walkability, and the availability and spread of entertainment sites within 15-min isochrones accessible by foot, bicycle, transit, and private vehicle. Notably, the central zone boasts diverse entertainment offerings, commendable walkability, and a substantial proportion of short and long trips. It is found that GPS traces are within their home. However, the share of long trips for the inhabitants of central zones is considerably more significant than that for the suburbs. The study highlights suburban zones that could benefit from governmental intervention to enhance transportation and pedestrian conditions. Additionally, it identifies other suburban zones that resemble the central areas in terms of walkability, trip distribution by distances, and the accessibility of entertainment places.

This study explores Bangladesh’s mental health services from an individual- and system-level perspective and provides insights and recommendations for strengthening it’s mental health system. We conducted 13 in-depth interviews and 2 focus group discussions. Thirty-one participants were recruited using a combination of purposive and snowball sampling methods. All interviews and group discussions were audio-recorded and transcribed, and key findings were translated from Bengali to English. Data were coded manually and analysed using a thematic and narrative analysis approach. Stakeholders perceived scarcity of service availability at the peripheral level, shortage of professionals, weak referral systems, lack of policy implementation and regulatory mechanisms were significant challenges to the mental health system in Bangladesh. At the population level, low levels of mental health literacy, high societal stigma, and treatment costs were barriers to accessing mental healthcare. Key recommendations included increasing the number of mental health workers and capacity building, strengthening regulatory mechanisms to enhance the quality of care within the health systems, and raising awareness about mental health. Introducing measures that relate to tackling stigma, mental health literacy as well as building the capacity of the health workforce and governance systems will help ensure universal mental health coverage.

This article argues that the Rights of Nature (RoN) framework is compatible with various ideological outlooks and political options. As a result, those initiatives may translate into extremely diverse institutional implementations with contrasted outcomes in terms of power distribution. The institutional design of RoN has deep political implications for various social groups who hold conflicting claims over certain territories. Hence, rather than transforming human-nature relations, RoN primarily transform the power relations between human communities. I delve into three conceptual frameworks that could shape the recognition of RoN and explore their respective distributive implications: green colonialism, environmental justice, and the focus on Indigeneity. Through this critical engagement, I wish to warn against the illusion of a post-political ecology where an ecocentric legal declaration would deliver human-nature harmony without deep political battles, social tensions, and economic confrontations. RoN as an abstract notion does not offer a ready-made toolkit to dismantle the legal architecture of fossil capitalism; nor does it provide clear guidance on the distribution of costs and benefits of the green transition.

At least 200 billion black soldier fly (Hermetia illucens) larvae (BSFL) are reared each year as food and feed, and the insect farming industry is projected to grow rapidly. Despite interest by consumers, producers, and legislators, no empirical evidence exists to guide producers in practicing humane – or instantaneous – slaughter for these novel mini-livestock. BSFL may be slaughtered via freezing, boiling, grinding, or other methods; however standard operating procedures (SOPs) and equipment design may affect the likelihood of instantaneous death using these methods. We tested how larval body size and particle size plate hole diameter affect the likelihood of instantaneous death for black soldier fly larvae that are slaughtered using a standard meat grinder. Larval body size did not affect the likelihood of instantaneous death for larvae that are 106–175 mg in mass. However, particle size plate hole diameter had a significant effect on the likelihood of instantaneous death, with only 54% of larvae experiencing an instant death when using the largest particle size plate (12-mm hole diameter) compared to 84% using the smallest particle size plate (2.55 mm). However, a higher percentage of instantaneous death (up to 99%) could be achieved by reducing the proportion of larvae that become stuck in the machine. We conclude by outlining specific recommendations to support producers in achieving a 99% instantaneous death rate through specific SOPs to be used with similarly designed machines. We also develop a protocol for producers that wish to test their own grinding SOPs.

Felt presence is a widely occurring experience, but remains under-recognised in clinical and research practice. To contribute to a wider recognition of the phenomenon, we aimed to assess the presentation of felt presence in a large population sample (n = 10 447) and explore its relation to key risk factors for psychosis. In our sample 1.6% reported experiencing felt presence in the past month. Felt presence was associated with visual and tactile hallucinations and delusion-like thinking; it was also associated with past occurrence of adverse events, loneliness and poor sleep. The occurrence of felt presence may function as a marker for general hallucination proneness.

The gravity of the crime committed has been considered ‘a factor of fundamental importance’ when deciding the early release of a person convicted by the ad hoc tribunals. Hence, most of the decisions rendered by the International Criminal Tribunal for the former Yugoslavia, for Rwanda and the International Residual Mechanism for Criminal Tribunals include this factor and determine whether it weighs in favour of or against early release. Conversely, when deciding the reduction of the sentence in the case of Thomas Lubanga, the International Criminal Court Panel stated in 2015 that ‘unlike at other international criminal tribunals, the gravity of the crime committed is not a factor that in itself weighs for or against reduction of sentence’. In fact, none of the decisions delivered by the International Criminal Court to date mention gravity. This drastic change reflects the differences in the corresponding statutes and rules of procedure and evidence and ultimately seeks to avoid a double count since the gravity of the crime committed is arguably the most important factor in the determination of the sentence. This divergence is examined in greater detail in this article, drawing on comparative, empirical research to establish the role played by gravity in early release decisions. Ultimately, it is argued that although the explanatory power generally attributed to gravity is often overrated, it is essential to a thorough early release assessment, whether included as a prerequisite per se or indirectly integrated into a wider prognosis of the risk of recidivism.
