Prey depletion, interspecific competition, and the energetics of hunting in endangered African wild dogs, .

Large herbivores are in decline in much of the world, including sub-Saharan Africa, and true apex carnivores like the lion () decline in parallel with their prey. As a consequence, competitively subordinate carnivores like the African wild dog () are simultaneously experiencing a costly reduction in resources and a beneficial reduction in dominant competitors. The net effect is not intuitively obvious, but wild dogs' density, survival, and reproduction are all low in areas that are strongly affected by prey depletion.

Spatial and Temporal Relationships Between Roe and Red Deer in an Alpine Area.

Interspecific interactions are important drivers of population dynamics and species distribution. These relationships can increase niche partitioning between sympatric species, which can differentiate space and time use or modify their feeding strategies. Roe deer and red deer are two of the most widespread ungulate species in Europe and show spatial and dietary overlap.

A power dependence model of the impact of leader impostorism on supervisor support and undermining: The moderating role of power distance.

Leaders, often perceived as possessing exceptional confidence and competence, are not immune to feelings of self-doubt. Leader impostorism describes the experience that one's attributes, experiences, skills, and abilities fall short of the standards expected in the leadership role, resulting in a sense of deception in fulfilling leadership responsibilities. While existing research has examined the antecedents and individual outcomes of leader impostorism, its implications for leaders' treatment of subordinates remain largely unexplored.

Novel Bat-Monitoring Dataset Reveals Targeted Foraging With Agricultural and Pest Control Implications.

Quantifying ecosystem services provided by mobile species like insectivorous bats remains a challenge, particularly in understanding where and how these services vary over space and time. Bats are known to offer valuable ecosystem services, such as mitigating insect pest damage to crops, reducing pesticide use, and reducing nuisance pest populations. However, determining where bats forage is difficult to monitor.

Positive and Negative Affect Differentially Predict Individual Differences and Intra-Individual Changes in Daily Cognitive Failures in Younger and Older Adults.

(1) Background: Cognitive failures, including lapses in attention, memory, and executive functioning, can negatively affect daily performance and well-being. Negative and positive affectivity have been implicated in cognitive functioning, yet their relationship with cognitive failures remains underexplored. This study investigates the impact of positive and negative affect on cognitive failures, using daily diary methods to examine both within-person and between-person associations in a sample of younger adults from Singapore and adults across the lifespan from the United States (US).

Perception of Socioeconomic Status: A Meta-Analysis of Manipulations.

The causal effects of one's socioeconomic status (SES) on outcomes are typically examined by experimentally manipulating SES self-perceptions based on one of three SES dimensions-absolute resource, relative resource, and general social position. We investigated the efficacy of these manipulations by systematically meta-analyzing their effects on SES self-perceptions. Based on 107 eligible samples ( = 26,203), manipulations of SES self-perceptions across the three SES dimensions were effective overall ( = 0.

The social welfare effect of e-commerce product reputation information asymmetry from the perspective of network externality.

Reputation is the most important intangible asset of merchants. In the e-commerce platform market, reputation information has become an important signal of product quality. However, with increasingly fierce competition among merchants on these platforms, violations of reputation information, such as "click farming," "cash rebate for favorable comments," and "pay per click," have caused information asymmetry and adverse selection.

On the probability of necessity and sufficiency of explaining Graph Neural Networks: A lower bound optimization approach.

The explainability of Graph Neural Networks (GNNs) is critical to various GNN applications, yet it remains a significant challenge. A convincing explanation should be both necessary and sufficient simultaneously. However, existing GNN explaining approaches focus on only one of the two aspects, necessity or sufficiency, or a heuristic trade-off between the two.

From schools of thought to an ecology of practices: Categorizing circular economy's futures.

In response to pressing societal challenges, scholars are increasingly focusing on research aimed at fostering sustainable futures. We contribute to that discussion by theorizing the circular economy (CE) as an "ecology of practices." The ecology of practices concept helps to make sense of a developing field that has been heavily practitioner-driven.

The Influence of Native Deer on Forest Fauna-A Systematic Map.

Deer are the most abundant large herbivores in temperate and boreal forests across the Northern Hemisphere. They are ecosystem engineers known to alter understory vegetation and future tree species composition by selective browsing. Also, deer have strong impacts on faunistic groups, often mediated by vegetation.

AttentionEP: Predicting essential proteins via fusion of multiscale features by attention mechanisms.

Identifying essential proteins is of utmost importance in the field of biomedical research due to their essential functions in cellular activities and their involvement in mechanisms related to diseases. In this research, a novel approach called AttentionEP for predicting essential proteins (EP) is introduced by attention mechanisms. This method leverages both cross-attention and self-attention frameworks, focusing on enhancing prediction accuracy through the integration of features across diverse scales.

Data journey map: a process for co-creating data requirements for health care artificial intelligence.

The Caribbean small island developing states have limited resources for comprehensive health care provision and are facing an increasing burden of noncommunicable diseases which is driven by an aging regional population. Artificial intelligence (AI) and other digital technologies offer promise for contributing to health care efficiencies, but themselves are dependent on the availability and accessibility of accurate health care data. A regional shortfall in data professionals continues to hamper legislative recognition and promotion of increased data production in Caribbean countries.

Individual liberty, safety and police liabilities under the mental health (care and treatment) act.

How should a society strike a balance between the objective of ensuring safety from dangers that may be posed by individuals believed to have a mental disorder and the deprivation of their liberty? How should police officers discharge their duties in apprehending such individuals with a view to conveying them to a medical practitioner at a psychiatric institution? These legal issues took centrestage in the Singapore High Court decision of Mah Kiat Seng v Attorney-General in which the apprehended individual brought claims in false imprisonment against a police officer. The decision examined the underlying purposes of the Singapore Mental Health (Care and Treatment) Act, the right of the person to be informed of the grounds of apprehension, the bases of the police officer's belief that the person posed a danger to himself or others, and the circumstances in which the police officers may be entitled to immunity from liability to civil or criminal proceedings. The High Court judgment led to statutory amendments to clarify police duties when apprehending such individuals and discussions about enhancements to police training and crisis support services for persons with mental illnesses.
