Legal support for the sustainable development of indigenous minorities of the North, Siberia and the Far East: results and prospects

The article examines the features of the legal regulation of the sustainable development of the indigenous peoples of the North, Siberia and the Far East. Special attention is paid to the Concept of Sustainable development of the indigenous peoples of the North, Siberia and the Far East in the context of updating this document in the near future. The Russian Federation is a multinational state, for which taking into account the traditions, culture and historically established way of life of each people living on its territory is one of the main directions of state policy. The indigenous peoples of the North are a social group that requires additional state support, not only because of their small number, but also because of the difficult climatic conditions of the places where these peoples live. The article considers the configuration of legal regulation in the field of sustainable development of indigenous peoples both in historical retrospect and at the present stage. Special attention is also paid to promising areas of development of state regulation, as well as measures of state support in this area. It is noted that at present the legal regulation of the sustainable development of the indigenous peoples of the North, Siberia and the Far East is at the stage of significant changes. The paper identifies the main differences between the current Concept and the Draft of the future one, concerning the fundamental aspects of policy. In particular, the principle of recognizing the right of the peoples of the North to priority access to fishing grounds and hunting grounds, to biological resources in places of their traditional residence and traditional economic activity, as well as modernization, updating of technical equipment, etc. At the same time, the author draws attention to the need to comply with environmental requirements and respect for nature in the process of implementing new tasks.

Temporal and spatial variation in reproductive benefits in a partial migrant.

In partial migrant systems, where residents and migrants coexist within a population, residents are commonly predicted to gain a reproductive advantage over migrants through priority access to high-quality territories and an earlier breeding start. Annual variation in reproductive benefits has been suggested to be important for the coexistence of both strategies in a population, as differences in wintering conditions experienced by the two strategies may result in a periodic reproductive advantage for migrants. However, the importance of spatial environmental variation for reproductive output in partially migrant populations remains largely unexplored. We investigated variation in the reproductive output of migrants and residents in a population of Swiss red kites (Milvus milvus) both temporally, across and within years, and spatially, along an elevational gradient. We gathered 4 years of reproductive data combined with 183 GPS-derived full annual cycles from individuals breeding in the Swiss Alpine foothills. At low, but not high, elevations, residents produced more fledglings than migrants. We also found evidence for annual variation in the reproductive advantage of the two strategies. Furthermore, while reproductive output did decline with a later breeding start, there was no difference in the start of breeding between the two migration strategies. The results of this study suggest that differences in reproductive output between migrants and residents in partial migrant populations can vary both due to the use of spatially distinct overwintering grounds and because the strategies are differently affected by spatial variables in the breeding area, such as elevation. The study emphasizes that spatial and temporal variation in reproductive benefits must be considered when predicting how migratory species will respond to future environmental change.

Age, sex, and temperature shape off-territory feeder use in black-capped chickadees.

Spatial ecology tends to focus on average movement patterns within animal groups; however, recent studies highlight the value of considering movement decisions both within and among individuals. We used a marked population of black-capped chickadees (Poecile atricapillus), to assess the causes and consequences of within- and among-individual differences in chickadee space use. Individuals that used feeders in addition to their most-visited "core feeder" were defined as engaging in off-territory feederuse. We found that females were more likely than males to visit off-territory feeders as ambient temperatures decrease and energetic demands increase. This may be due to sex-related differences in dominance, where males which are the dominant sex in chickadees, have priority access to feeders, while females must increase their foraging areas to meet higher energetic demand. We also found that independent of temperature, adult males were less likely than juvenile males and both juvenile and adult females to forage off-territory. We suggest that this may be due to age-specific benefits of space use in males, where un-paired juvenile males may increase feeder exploration to gain information about potential mates. Finally, we found that chickadees that had a higher propensity to visit off-territory feeders were less likely to survive to the next fall. Overall, our results suggest that dominance hierarchies and individual energetics impact within- and among-individual variation in off-territory feeder use. We provide suggestions for future studies to further investigate fitness-related consequences of within- and among-individual variation in space use.

Does 4IR and Covid 19 Effect The Quality of Work Life and Living Standard of Women Workers? Evidence from Selected RMG Firms in Bangladesh

Purposes The study's main objective is to find out the impact of the fourth industrial revolution and covid-19 on women workers of selected Ready-Made Garments (RMG) sector in Bangladesh. Methodology This study mainly followed a quantitative research approach with survey study. Total 18 garments (case) has been chosen randomly from DSE listed RMG firm based on access priority. Sample size for survey study has been determined by statistical method is 384. But this study consider total (15*27) = 405. Data have been collected from selected respondents (women workers) using structured questionnaire. Findings The study reveals that women workers in the RMG sector exhibit a remarkable lack of anxiety about their work-life quality, largely due to their experience and resilience in handling the challenges of their profession. It highlights the adaptability of these workers and underscores the importance of targeted support and interventions to promote sustainable livelihoods and better working conditions amid persistent challenges. Implications The study's findings can inform policymakers about the specific challenges faced by women workers in the RMG sector due to the convergence of 4IR and the COVID-19 pandemic. Originality/Value this study's originality and value lie in its intersectional analysis, empirical evidence, contextual specificity, practical implications, and contributions to knowledge, all of which enrich our understanding of the complex dynamics shaping the lives of women workers in Bangladesh's RMG sector amidst the challenges of 4IR and COVID-19. Limitations The study's findings may be limited by the scope of the selected RMG firms and the sample size of women workers included in the research. While efforts were made to ensure diversity within the sample, the findings may not be representative of all women workers in the RMG sector in Bangladesh, limiting the generalizability of the results.

Risk of Relapse After COVID-19 Vaccination Among Patients With Multiple Sclerosis in France: A Self-Controlled Case Series.

People with multiple sclerosis (MS) have an increased risk of severe coronavirus infection due to their level of motor disability or exposure to certain immunosuppressive treatments. Thus, patients with MS have had priority access to coronavirus disease 2019 (COVID-19) vaccination. However, relapses after vaccination have been reported, leading some patients to not seek the recommended booster doses. The main objective was to estimate the risk of severe relapse after 1, 2, and 3 (booster) doses of COVID-19 vaccination in patients with MS. The secondary objectives were to assess the risk of relapse in clinically meaningful subgroups according to the type of vaccine, the characteristics of the patients, and the use of disease-modifying treatments (DMTs). We conducted a nationwide study using data from the French National Health Data System. Patients with MS were identified according to ICD codes, specific treatments, and reimbursement data up to March 31, 2022. Relapses requiring treatment with high-dose corticosteroids were identified. A self-controlled case series method was used to evaluate the risk of relapse associated with COVID-19 vaccines in the 45 days after vaccination. The associated risk was evaluated after 1, 2, or 3 (booster) doses and is expressed as overall incidence rate ratios (IRRs) and in subgroups of interest. Overall, 124,545 patients with MS were identified on January 1, 2021, and 82% received at least 1 dose of a COVID-19 vaccine (n = 102,524) until December 31, 2021, for a total of 259,880 doses. The combined IRR for MS relapse was 0.97 (0.91-1.03, p = 0.30). The same absence of risk was confirmed in various subgroups (age younger than 50 years, duration of MS < 10 years, use of DMT). A small increase in the relapse risk cannot be excluded after a booster dose (IRR 1.39 [1.08-1.80]) for patients with high MS activity, especially when not treated. There is no increased risk of relapse requiring corticosteroid therapy after COVID-19 vaccination for almost all patients. We cannot exclude an increased risk after the booster dose for patients who have had at least 2 relapses in the previous 2 years. This study provides Class III evidence that COVID-19 vaccination does not increase the risk of severe relapse in patients with MS.

The promise and reality of middle-class homeownership in China: housing assetisation, speculative urban (re)development and residential inequalities

ABSTRACT This paper offers a nuanced understanding of China’s housing assetisation by (1) examining its role in supporting financialised urban (re)development after the global financial crisis, and (2) dissecting the contradictions between seemingly flourishing housing markets and deep-seated residential inequalities. Drawing on the case of Guangzhou, this paper first illustrates how housing assetisation internalizes financial norms within Chinese homeowner society, signifying a shift in the mode of social regulation from managerialism to entrepreneurialism. This shift is evident in the capitalization of priority access to public infrastructure and the prevailing culture of accumulation, investment and speculation. In the post-crisis era, housing has been repackaged as a lucrative investment by the local state through dazzling (sub)urban projects, large-scale infrastructure construction and ambitious urban-planning proposals, thereby fueling a home-buying frenzy. We argue that the assetisation-induced social ethos of capital accumulation and speculative investment, entwined with infrastructure-cum-property-led urban (re)development, has recast Chinese cities into shareholder-value machinery. As the local state leverages household savings and income streams to bolster land-based financialised urban development, homeowners/buyers are transformed into investor-citizens. This transformation implies that urban household balance sheets become intricately linked with China’s urban fortunes. Moreover, residential inequalities are exacerbated, exemplified by prevalent gentrification “at a premium”.

Unravelling the mechanisms underlying the social interaction effects on the feed efficiency of rabbits

The feed consumption and feeding patterns of group-housed livestock and their productive outputs can be affected by interactions among group members, such as competition for feeder access and aggression. The impact of competition is especially significant when feed restriction is implemented during the fattening stage, a common practice in rabbit farms to reduce mortality from digestive disorders during this period. The overall aim was to quantify the importance of social interaction effects at the genetic and environmental level on feed efficiency, feeding behaviour and social ranking traits in rabbit populations having access to electronic feeders whilst they were housed in groups during fattening. This was done by quantifying novel feeding behaviour (FB) and social ranking (SR) traits and by estimating the genetic parameters and genetic correlations between all combinations of direct and social effects of these traits and residual feed intake (RFI), an indicator of feed efficiency. These effects were estimated in animals fed either ad libitum (AL) or on a time-based feed restriction (R) and were selected for feed efficiency on these feeding regimes for six generations. We found that there were substantial social genetic and social litter effects on RFI and FB traits, manifesting as antagonistic relationships between direct and social genetic effects. These effects were stronger amongst the R, as opposed to the AL animals. Despite these antagonistic relationships, the large social genetic effects resulted in substantial heritable variation available for selection of these traits, and therefore feeding behaviour could be changed by genetic selection, especially for R animals. The indicators of an animal’s SR were also heritable and subject to social genetic effects and therefore may respond to selection. However, the phenotypic population mean would not change, because such traits are context−specific. The animals that took most of the feeding resources and had priority access to the feeder had a higher RFI, that is, they were less efficient, but they made their cage mates more efficient. This is the first time that the genetic correlations between direct effects of RFI and direct effects of FB and SR traits, as well as between social effects of RFI and direct effects of FB traits and SR traits, have been quantified. Results could help to understand the mechanisms by which an animal exerts its influence on the feed efficiency of its cage mates under different feeding regimes and assist in the development of breeding strategies.

Proposal for designing an independent housing unit for a Libyan family with limited income

One of the most critical needs for Libyan families is to have priority access to suitable and independent housing, enabling them to acquire and own it. This is a primary goal for designers, based on the needs of Libyan citizens. Providing housing opportunities for individuals of all ages, income levels, and abilities falls under citizens' rights that the Libyan state should ensure. However, the high cost of acquiring independent housing, due to its large size—the preferred model among Libyan families—and the difficulty of ownership, hinders the achievement of this goal. Recognizing that architectural design is an effective tool for providing suitable and independent housing, this paper aims to present a design experience for an independent, affordable house with an approximate area of 180 square meters on a 300-square-meter plot. The design meets the functional needs of Libyan families, while respecting their social, cultural, and religious requirements, and aligns with municipal building regulations and the design requirements of the Libyan Building Code. Keywords: Libyan housing, independent housing, design experience.

QoS-Oriented uplink OFDMA random access for the next-gen WLAN

Abstract OFDMA, introduced by the IEEE 802.11ax standard, divides the channel into multiple resource units (RUs), enabling parallel access for multiple users. On this basis, we propose a QoS-oriented double arbitration random access (Q-DARA) scheme. This scheme ensures high-priority priority access through priority arbitration in the first phase and random code arbitration in the second phase. It can also greatly reduce collisions and effectively guarantee the QoS of high-priority traffic. Simulation shows that our proposed scheme has better performance on throughput and latency. Compared to the traditional EDCA, the throughput and latency increase by more than 70%. Compared to the PATB scheme, the throughput increases by about 20%, and the latency increases by about 23%. Moreover, our proposed scheme has almost no changes to the protocol and is suitable for 802.11ax and beyond.

Non-firm vs priority access: On the long run average and marginal costs of renewables in Australia

In Australia, the National Electricity Market (NEM) has experienced a rapid expansion of Variable Renewable Electricity (VRE) projects, not without obstacles. Entry frictions such as movements in Marginal Loss Factors and/or network congestion adversely impacted ∼15% of new projects. Are these the expected results in a workably functioning market, or due to market design defects? Policy advisors have sought to reform the NEM's non-firm, open-access regime. As VRE market shares increase, curtailment will increase rapidly through excess generation and/or network congestion, given the ratio of maximum-to-average wind output is 3 times, and solar PV is 4 times. But access reform focused solely on congestion and curtailment may have unintended consequences as a careful analysis of the difference between average and marginal curtailment rates demonstrates. Malalignment between market conventions and access policy may distort entry, raise consumer prices and harm welfare. Our model results confirm that switching from open- to priority access in Australia's NEM and REZ in particular damages consumer and producer welfare materially.

Acquisition of land ownership rights by foreign persons according to the laws of Ukraine and Canada

The article conducts a comparative legal study of the specifics of acquisition and exercise of land ownership by foreigners, stateless persons and foreign legal entities under the legislation of Ukraine and Canada, as a result of which the Canadian experience of legal regulation in the specified area, which is most acceptable for Ukraine, is substantiated. It has been established that in the science of land law of Ukraine, one of the most controversial issues is the possibility, scope, conditions and grounds of granting land ownership rights to foreigners, stateless persons, and foreign legal entities, especially considering the provisions of Art. 13 of the Constitution of Ukraine, which declares all land to be the property of the Ukrainian people. This issue has not been resolved definitively in the land legislation, as access of foreign persons to ownership of agricultural land can be granted only after a positive decision of the All-Ukrainian referendum. The conducted research showed that Canadian legislation provides for the possibility of establishing restrictions on the acquisition of land ownership by foreign entities both at the federal level (a two-year restriction on the purchase of residential real estate, including vacant land plots intended for residential development), and at the level of individual provinces and territories. At the level of the provinces and territories, there are different legal models for restricting the access of foreign persons to the right to ownership of land, primarily for agricultural purposes. There are no legal restrictions on the acquisition of the right to ownership of land by foreign persons in British Columbia, Ontario, Newfoundland and Labrador, New Brunswick and Nova Scotia. At the same time, in Alberta, Saskatchewan, Manitoba, and Quebec, the access of foreigners to land ownership is significantly limited, in particular, by establishing the maximum size of land plots that they can acquire on ownership. The article claims that the establishment of restrictions in Canadian legislation on the acquisition of ownership rights to land, primarily for agricultural purposes, is conditioned by the need to ensure priority access to the lands of Canadian citizens and Canadian corporations, which can be a reference point for the settlement of these issues in Ukrainian land law. Canadian legislation, both at the federal level and at the level of individual provinces and territories, provides effective mechanisms of legal responsibility in the event of violation of legal restrictions on foreign persons' access to land ownership, which should be provided for in Ukrainian legislation.

Changing rules, recommendations, and risks: COVID-19 vaccination decisions and emotions during pregnancy

As COVID-19 vaccinations rolled out globally from late 2020, rules and recommendations regarding vaccine use in pregnancy shifted rapidly. Pre-registration COVID-19 vaccine trials excluded those who were pregnant. Initial Australian medical advice did not routinely recommend COVID-19 vaccines in pregnancy, due to limited safety data and little perceived risk of local transmission. Advice from local medical authorities changed throughout 2021, however, with recommendations and priority access during pregnancy. In Western Australia (WA), recommendations became requirements as the State government mandated vaccines for some workers, with brief availability of pregnancy exemptions. Through an examination of 10 in-depth interviews with WA pregnant women, we explore their decision-making and complex emotions regarding COVID-19 vaccinations, and how they balanced mandates, recommendations, and shifting considerations and perceptions of risk. Changing recommendations and rules—and media and popular interpretation and communications of these—led to confusion, including for medical professionals. Expectant parents had to negotiate the risks of COVID-19 disease, potential benefits and risks of vaccination, professional and personal costs of vaccine refusal, and interpret mixed medical advice. Our findings can inform the development and communication of public health policies and medical advice, and contribute to our understanding of bodily autonomy, risk, and decision-making beyond the pandemic.

Public support for proposed government policies to optimise the social benefits of autonomous vehicles

Governments will have a key role in establishing the policy environment needed to optimise the social outcomes associated with the evolution of autonomous vehicles (AVs). However, little is known about the extent to which the general public would support the diverse range of policies that could be implemented across human transport and product delivery AV applications. To address this deficit, the aim of the present study was to explore public support for a range of human transport and product delivery AV policies. In total, 1078 adult Australians completed an online survey that assessed transport-related attitudes and behaviours, including support for 11 AV policies pertaining to human transport and product delivery AV applications. Results suggest policies that ensure walking and cycling paths are prioritised for active transport (supported by 65%), limit the numbers of personal flying passenger AVs in the airspace (62%) and delivery bots on streets (64%), and ensure that those with mobility limitations have priority access to autonomous product deliveries (60%) are likely to be acceptable to the general community. To a somewhat lesser extent, limiting the operating hours for AV delivery services (51%) and banning the advertising of unhealthy foods and beverages on the surface areas of delivery AVs (50%) are also likely to be broadly accepted.

Novel phenotypes of feeding and social behaviour and their relationship with individual rabbit growth and feed efficiency

Due to the lack of a recording system for individual consumption of group-housed rabbits, published studies about feeding behaviour are based on information recorded at the group- and not at the individual level and periods covering only a few days or, in some cases, only part of a day. Such information could be used to inform rabbit management systems but cannot be used for genetic selection. We aimed to generate and use information from a novel automated feeder for group-housed rabbits to identify new phenotypes for individual animals that could be incorporated into breeding programs to improve feed efficiency and social behaviour under different feeding regimens. At 39 d of age, rabbits from 15 batches were placed in cages and fed ad libitum to become used to the electronic feeder. From 42 to 58–59 d, one group of 1 086 rabbits was fed ad libitum (AL), while another group of 1 134 rabbits was fed on a restricted feeding schedule (R) by limiting the feeding time to the period between 1800 and 0600 h of the following day. We implemented a reliable multivariate method to remove anomalous feeding behaviour records. We then defined novel traits for feeding behaviour that apply to both types of feeding regimes, and for social behaviour that indicates an animal’s rank within the cage hierarchy. We based these traits on feeder records and a biologically sound definition of a meal. Finally, we estimated the phenotypic correlations of those traits with growth and feed efficiency traits. Our findings demonstrate that variables about resource distribution among cage mates and an animal's priority for feed access were found to be good indicators of an animal's dominant or subordinate status within the cage. Based on results obtained in R animals (results were similar in AL animals), the most efficient animals were those that ate less frequently (phenotypic correlation with feed conversion ratio, rho = 0.6), and consumed smaller amounts per meal (rho = 0.7), spent less time at the feeder (rho = 0.4), and appeared to be subordinate, as they did not have priority access to the feeder (rho = −0.3), and had the smallest share of resources (range of rho = 0.2–0.6). We conclude that quantifying feeding and social behaviour traits can enhance the understanding of the mechanisms through which individuals exert their effects on the performance of their cage mates.

Single cell transcriptomic representation of social dominance in prefrontal cortex and the influence of preweaning maternal and postweaning social environment

Social dominance encompasses winning dyadic contests and gaining priority access to resources and reproduction. Dominance is influenced by environmental factors, particularly during early postnatal life and adolescence. A disinhibitory medial prefrontal cortex (mPFC) microcircuit has been implicated in the expression of dominance in the “tube test” social competition paradigm in mice, but the neuroplasticity underlying dominance is not known. We previously reported that male pups raised by physically active (wheel-running, as opposed to sedentary) dams exhibit tube test dominance and increased reproductive fitness, and here we show that social isolation from weaning also increases dominance. By using single cell transcriptomics, we tested if increased dominance in these models is associated with a specific transcriptional profile in one or more cell-types in the mPFC. The preweaning maternal effect, but not postweaning social isolation, caused gene expression changes in pyramidal neurons. However, both the effect of maternal exercise and social isolation induced the coordinated downregulation of synaptic channel, receptor, and adhesion genes in parvalbumin positive (PV) interneurons, suggesting that development of dominance is accompanied by impaired PV interneuron-mediated inhibition of pyramidal cells. This study may help understand environmentally induced transcriptional plasticity in the PFC and its relationship to tube test dominance.

Comparative Analysis of Two Educational Systems in Both Basic and Higher Education between Japan and Singapore

The comparative analysis of the educational systems in Japan and Singapore, encompassing both basic and higher education, reveals intriguing insights into the diverse approaches employed by these nations. In terms of basic education structure, Japan follows a 6-3-3 system, comprising six years of elementary education, three years of junior high, and three years of senior high, while Singapore adopts a 4-4-4 system, dividing education into four years each of primary, secondary, and pre-university or vocational education. This structural contrast sets the stage for examining curriculum, instructional methods, assessment practices, teacher training, funding mechanisms, equity considerations, and educational outcomes. Japan's emphasis on national standards and rote learning is juxtaposed against Singapore's focus on critical thinking, problem-solving, and creativity, reflecting varied pedagogical philosophies. Instructional methods further differ, with Japan relying on traditional teacher-centered approaches and Singapore embracing diverse strategies like project-based and collaborative learning. Assessment practices showcase Japan's reliance on standardized national exams, while Singapore employs diverse methods such as internal exams and portfolios. In teacher training, Japan emphasizes subject knowledge and standardized training, while Singapore prioritizes pedagogical skills, continuous professional development, and career progression. The funding landscape diverges, with Japan primarily relying on public funding and limited private involvement, while Singapore fosters a robust public-private partnership for funding and innovation. Equity and access priorities also differ, with Japan expressing concerns about rural-urban disparities, and Singapore emphasizing equal access for all students. Notably, both nations achieve high PISA scores, but Japan grapples with concerns about rote learning and student stress, whereas Singapore excels in international benchmarks. This comparative analysis underscores the nuanced and multifaceted nature of educational systems, providing valuable insights for policymakers, educators, and researchers seeking to understand and learn from the diverse approaches adopted by Japan and Singapore.

Association between Priority Conditions and Access to Care, Treatment of an Ongoing Condition, and Ability to Obtain Prescription Medications among Medicare Beneficiaries during the COVID-19 Pandemic

Several comorbid conditions have been observed to be associated with an increased risk of poor outcomes following a diagnosis of COVID-19. The purpose of this investigation was to assess associations between Centers for Medicare and Medicaid Services (CMS) designated priority conditions and an inability to access care, treat ongoing conditions, and obtain prescription medications among Medicare beneficiaries in the United States during the COVID-19 pandemic. Nationally representative CMS Medicare Current Beneficiary Survey (MCBS) COVID-19 Supplement Public Use Files (PUF) were analyzed via bivariable, binomial generalized linear models across three time periods: (1) Summer 2020; (2) Fall 2020; and (3) Winter 2021. Across an estimated 55.3–57.4 million Medicare beneficiaries, approximately one-fifth reported an inability to access at least one type of care at the onset of the pandemic. Significantly worse odds of an ability to get care across various time periods was observed among several priority conditions including immune disorders, cancer, depression, osteoporosis, diabetes, arthritis, and numerous cardiovascular and pulmonary conditions. Among those reporting an inability to access care, approximately one-third involved treatment of an ongoing condition, and under one-tenth involved prescription medications. To identify modifiable risk factors and to develop active interventions, future work should continue to assess the complex associations between outcomes, access to care, comorbidities, evolving healthcare infrastructures, computerization, and various public health initiatives.

Information Gathering Is Associated with Increased Survival: A Field Experiment in Black-Capped Chickadees (Poecile atricapillus).

AbstractSampling, investing time or energy to learn about the environment, allows organisms to track changes in resource distribution and quality. The use of sampling is predicted to change as a function of energy expenditure, food availability, and starvation risk, all of which can vary both within and among individuals. We studied sampling behavior in a field study with black-capped chickadees (Poecile atricapillus) and show that individuals adjust their use of sampling as a function of ambient temperature (a proxy for energy expenditure), the presence of an alternative food source (yes or no, a proxy for risk of energy shortfall), and their interaction, as predicted by models of optimal sampling. We also observed repeatable differences in sampling. Some individuals consistently sampled more, and individuals that sampled more overall also had a higher annual survival. These results are consistent with among-individual differences in resource acquisition (e.g., food caches or dominance-related differences in priority access to feeders), shaping among-individual differences in both sampling and survival, with greater resource acquisition leading to both higher sampling and higher survival. Although this explanation requires explicit testing, it is in line with several recent studies suggesting that variation in resource acquisition is a key mechanism underlying animal personality.
