Secretary bird optimization algorithm: a new metaheuristic for solving global optimization problems

This study introduces a novel population-based metaheuristic algorithm called secretary bird optimization algorithm (SBOA), inspired by the survival behavior of secretary birds in their natural environment. Survival for secretary birds involves continuous hunting for prey and evading pursuit from predators. This information is crucial for proposing a new metaheuristic algorithm that utilizes the survival abilities of secretary birds to address real-world optimization problems. The algorithm's exploration phase simulates secretary birds hunting snakes, while the exploitation phase models their escape from predators. During this phase, secretary birds observe the environment and choose the most suitable way to reach a secure refuge. These two phases are iteratively repeated, subject to termination criteria, to find the optimal solution to the optimization problem. To validate the performance of SBOA, experiments were conducted to assess convergence speed, convergence behavior, and other relevant aspects. Furthermore, we compared SBOA with 15 advanced algorithms using the CEC-2017 and CEC-2022 benchmark suites. All test results consistently demonstrated the outstanding performance of SBOA in terms of solution quality, convergence speed, and stability. Lastly, SBOA was employed to tackle 12 constrained engineering design problems and perform three-dimensional path planning for Unmanned Aerial Vehicles. The results demonstrate that, compared to contrasted optimizers, the proposed SBOA can find better solutions at a faster pace, showcasing its significant potential in addressing real-world optimization problems.

A Behavioral Model of Responsible Sourcing in Supply Chains: The Role of Dual-Sourcing Bias

Decision on what consumer reactions (support or boycott) to promote is important for nongovernmental organizations and policymakers looking to influence firms’ adoption of corporate social responsibility practices. We study how consumer reactions—paying more for certified products or boycotting in the event of responsibility violations—are effective in improving a firm’s uptake of responsibility practices in the sourcing domain. We first build a stylized model to study how consumer reaction affects a firm’s incentives toward responsible sourcing and find that only boycotting reactions by consumers reliably increases a firm’s sourcing from responsible suppliers. We then include behavioral aspects to our stylized model to derive a more nuanced understanding of how consumer reactions affect responsible sourcing. Through behavioral experiments, we first show that a supporting consumer reaction induces a dual-sourcing bias in firms’ sourcing decisions. We then develop a behavioral model of responsible sourcing, incorporating this dual-sourcing bias. Our analysis modifies the normative predictions of the stylized model by showing that a supporting reaction, irrespective of magnitude, always improves responsible sourcing if the boycotting reaction from the market is weak, and that promoting a boycotting reaction always improves responsible sourcing, irrespective of the product type. Our results lead us to a comprehensive and applicable insight for practice: in the supply chains of products with few brand substitutes, creating a supporting reaction in the market is the way to improve firms’ responsible sourcing, and in supply chains of products with many brand substitutes, promoting a boycotting reaction among consumers will lead to more responsible sourcing.

Gametocidal genes: from a discovery to the application in wheat breeding.

Some species of the genus Aegilops, a wild relative of wheat, carry chromosomes that after introducing to wheat exhibit preferential transmission to progeny. Their selective retention is a result of the abortion of gametes lacking them due to induced chromosomal aberrations. These chromosomes are termed Gametocidal (Gc) and, based on their effects, they are categorized into three types: mild, intense or severe, and very strong. Gc elements within the same homoeologous chromosome groups of Aegilops (II, III, or IV) demonstrate similar Gc action. This review explores the intriguing dynamics of Gc chromosomes and encompasses comprehensive insights into their source species, behavioral aspects, mode of action, interactions, suppressions, and practical applications of the Gc system in wheat breeding. By delving into these areas, this work aims to contribute to the development of novel plant genetic resources for wheat breeding. The insights provided herein shed light on the utilization of Gc chromosomes to produce chromosomal rearrangements in wheat and its wild relatives, thereby facilitating the generation of chromosome deletions, translocations, and telosomic lines. The Gc approach has significantly advanced various aspects of wheat genetics, including the introgression of novel genes and alleles, molecular markers and gene mapping, and the exploration of homoeologous relationships within Triticeae species. The mystery lies in why gametes possessing Gc genes maintain their normality while those lacking Gc genes suffer abnormalities, highlighting an unresolved research gap necessitating deeper investigation.

Detecting Overlapping Communities Based on Influence-Spreading Matrix and Local Maxima of a Quality Function

Community detection is a widely studied topic in network structure analysis. We propose a community detection method based on the search for the local maxima of an objective function. This objective function reflects the quality of candidate communities in the network structure. The objective function can be constructed from a probability matrix that describes interactions in a network. Different models, such as network structure models and network flow models, can be used to build the probability matrix, and it acts as a link between network models and community detection models. In our influence-spreading model, the probability matrix is called an influence-spreading matrix, which describes the directed influence between all pairs of nodes in the network. By using the local maxima of an objective function, our method can standardise and help in comparing different definitions and approaches of community detection. Our proposed approach can detect overlapping and hierarchical communities and their building blocks within a network. To compare different structures in the network, we define a cohesion measure. The objective function can be expressed as a sum of these cohesion measures. We also discuss the probability of community formation to analyse a different aspect of group behaviour in a network. It is essential to recognise that this concept is separate from the notion of community cohesion, which emphasises the need for varying objective functions in different applications. Furthermore, we demonstrate that normalising objective functions by the size of detected communities can alter their rankings.

What does it mean to be good at peer reviewing? A multidimensional scaling and cluster analysis study of behavioral indicators of peer feedback literacy

Peer feedback literacy is becoming increasingly important in higher education as peer feedback has substantially grown as a pedagogical approach. However, quality of produced feedback, a key behavioral aspect of peer feedback literacy, lacks a systematic and evidence-based conceptualization to guide research, instruction, and system design. We introduce a novel framework involving six conceptual dimensions of peer feedback quality that can be measured and supported in online peer feedback contexts: reviewing process, rating accuracy, feedback amount, perceived comment quality, actual comment quality, and feedback content. We then test the underlying dimensionality of student competencies through correlational analysis, Multidimensional Scaling, and cluster analysis, using data from 844 students engaged in online peer feedback in a university-level course. The separability of the conceptual dimensions is largely supported in the cluster analysis. However, the cluster analysis also suggests restructuring perceived and actual comment quality in terms of initial impact and ultimate impact. The Multi-Dimensional Scaling suggests the dimensions of peer feedback can be conceptualized in terms of relative emphasis on expertise vs. effort and on overall review quality vs. individual comment quality. The findings provide a new road map for meta-analyses, empirical studies, and system design work focused on peer feedback literacy.

Legal behavior and human identity in the debate paradigm of the philosophy of law

This article analyzes the peculiarities of the reflection of a person’s legal behavior in the light of various philosophical and legal scientific discourses. In general, the analysis of a person’s legal behavior in the debatable paradigm of the philosophy of law in the context of studying the problem of establishing legal cooperation illuminates the deep aspects of the interaction between the individual and the legal system. Philosophical concepts help to consider this topic on a metaphysical level, revealing the fundamental principles and moral aspects of legal behavior.
 It was established that the primary springboard for considering behavior in the context of legal reality is its consideration through the ideological paradigm of human rights, since the concept recognizes the inalienability and inalienability of the rights of each person, justifying their fundamentality due to the presence of dignity inherent to each person. The main idea is that these rights are not only legal norms, but also a key element that forms personal dignity and freedom and express the personal identity of a person, and in evaluating human behavior, the role of the state and society in ensuring and protecting rights as an unconditional axiological determinants.
 It is proved that a valid paradigm of reflection is the need to analyze behavior in the prism of a social contract, since the mutual agreement of people involves the exchange of a part of individual freedom for common order and security, ensured by the adoption of rules and obligations, which forms the basis for the creation of the state and the legal order. Thus, a person’s behavior is evaluated for its compliance with established rules and the ability to interact with other members of society in peace and mutual understanding.
 It is motivated that the philosophical analysis of ethical-philosophical concepts in the context of human behavior defines two key areas - deontology and consequentology. Deontology, focusing on duties and rules, determines the morality of actions regardless of their consequences, indicating the obligation of ethical norms, and consequentology focuses on the consequences of actions as the main criterion for their moral evaluation, emphasizing the importance of positive results.

Discrete modeling of elastic heterogeneous media

Discrete models provide advantages in simulating fracture in quasi-brittle materials due, in part, to their simplicity in representing cracking and other forms of displacement discontinuity. However, the stress analyses that form the basis for fracture simulation are complicated by difficulties in modeling the Poisson effect and other aspects of elastic behavior. The capabilities of Voronoi-cell lattice models, which are a form of particle-based lattice model, for elastic stress analysis are evaluated. It is found that the conventional means for representing the Poisson effect in particle-based lattice models result in spatially correlated stress oscillations that, at first glance, mimic the effects of material heterogeneity. The correlation length is dependent on discretization size. Alternatively, material heterogeneity can be introduced into elastically uniform lattice models via random assignments of material properties, independent of mesh size and geometry.

Examining the Shift in Orderly Cultural Behavior and Cultural Cooperative Learning Behavior among Students: A Pre- and Post-Experiment Perception Analysis

Objective: This study conducted a pre- and post-experiment perception analysis to examine the changes in orderly cultural behavior and cultural cooperative learning behavior among students. Method: The research involved 89 participants and utilized self-report questionnaires to collect data on various aspects of cultural behavior. The results showed significant improvements in both orderly cultural behavior and cultural cooperative learning behavior after the intervention. Results and Discussion: The percentage of students exhibiting good levels of orderly cultural behavior increased from 14.6% to 32.6%, while the proportion of students demonstrating good levels of cooperative learning behavior increased from 9% to 21.3%. The study also found a strong positive correlation between orderly cultural behavior and academic performance. These findings emphasize the importance of fostering cultural behavior and incorporating cooperative learning strategies in educational settings. Research Implications: The study suggests the need for interventions that promote cultural understanding and cooperation among students. However, the study has limitations in terms of sample size and generalizability. Future research should involve larger and more diverse samples to validate the findings. Originality/Value: In conclusion, this study highlights the positive shifts in cultural behavior and learning outcomes among students and emphasizes the significance of creating inclusive and culturally sensitive learning environments.

An Analysis of the Behavioural Persistence of Tree-growing Farmers in the Sudano-Sahelian Region of Cameroon

Tree-growing support programs are being implemented widely to enhance farmers’ involvement in land restoration schemes. However, the reasons why farmers will continue to engage in restoration activities when support programs end, considered here as “behavioural persistence” has not been sufficiently explored. Taking the Mogazang landscape of Cameroon as a case study, a mixed methods approach involving farmers surveys, key informant interviews and the review of literature, was applied to investigate the factors that influence the behavioural persistence of tree-growing farmers. Drawing on the concept of behavioural persistence, the findings revealed that farmers decision to continue restoration practices on their farm plots after the end of support programs is influenced by a mix of factors, among which positive attitude and perception of farmers, constant motivation, financial profitability, community influence, played an important role. Findings also showed that farmers behavioural persistence aspects were not adequately addressed during the design of support programs and the inception phase of support programs did not prepare farmers psychologically about post support programs. This empirical investigation of farmers behavioural persistence has provided information that needs to be taken into consideration when assessing the feasibility, including the designing and implementation of planned tree-growing restoration support programs and related policies in Cameroon and other countries.

Association between Levels of Loneliness, Laboratory Measurements, and Behavioral Aspects in a Primary Care Setting in Crete, Greece.

This paper examines potential associations of loneliness with laboratory data and specific psychosocial and behavioral attitudes. The sample collection took place in an urban Primary Health Care unit between May and July 2023, consecutively, and once exclusion criteria were implemented. Participants were aged between 40 and 75 years. Routine laboratory test results upon study initiation and six months before were used. The University of California, Los Angeles (UCLA), Loneliness Scale (Version 3), blood glucose, serum lipids, Fibrosis-4 index, and Creatinine Clearance (CrCl) were assessed through hierarchical multiple logistic regression analysis. Based on full model (3rd) analysis, those who were engaged in an individual sport or activity or had contacts with more friends presented significantly lower odds for increased loneliness levels (odds ratio (OR): 0.28 [95% confidence interval (CI) 0.09-0.91], p = 0.034 and OR: 0.76 [95%CI 0.66-0.88], p < 0.001, respectively). The consumption of alcohol was associated with increased loneliness (OR: 5.55 [95%CI 1.42-21.63], p = 0.014). Elevated triglyceride levels were linked with moderate or no loneliness (OR: 0.20 [95%CI 0.05-0.83], p = 0.026), while an increased LDL/HDL atherosclerotic index was related to increased subjective loneliness (OR: 4.50 [95%CI 1.12-18.13], p = 0.035). The need for holistic approaches-involving primary care personnel-in understanding and addressing loneliness, recognizing its multifaceted nature as well as the diverse factors that contribute to this issue, is considered challenging.

Preconception diet in adolescence and its association with hypertensive disorders of pregnancy and preterm birth. Results from the HUNT study.

Our aim was to estimate associations of adolescent dietary patterns and meal habits with hypertensive disorders of pregnancy (HDP) and preterm birth. We used data from a prospective cohort study (Norwegian Young-HUNT1) where dietary information was collected during adolescence and pregnancy outcomes were obtained through record linkage to the Norwegian national birth registry. The outcomes were HDP, hypertension, pre-eclampsia/eclampsia, and preterm birth in the first pregnancy and in any pregnancy. Diet was self-reported from validated questionnaires, and exposures were dietary indexes (healthy; unhealthy; fruit and vegetable; fibre index) and meal habits. Recruitment took place in schools. Eligible participants were females aged 13-19 years at the time of dietary assessment with a subsequent singleton pregnancy (n 3622). Women who reported a higher fibre intake in adolescence had a lower risk of pre-eclampsia in the first pregnancy (Relative Risk: 0·84; 95 % CI 0·7, 1·0), although this was weaker in sensitivity analyses. Regular meal habits in mid-adolescence (aged 13-15 years), particularly breakfast and lunch, were weakly associated with a lower risk of hypertension in pregnancy. Our results are the first to indicate an association between aspects of diet and dietary behaviour in mid-adolescence and subsequent HDP. More evidence is needed from larger studies to replicate the results and from alternative study designs to disentangle causality.

Characteristics and Consequences of Falls in People Who Use Wheelchairs in Long-Term Care Settings

ObjectivesThe purpose of this study was to understand the characteristics and consequences of falls in individuals using wheelchairs in long-term care settings. DesignObservational analysis of real-world falls in long-term care. Setting and ParticipantsResidents using wheelchairs from 2 long-term care facilities in British Columbia, Canada (n = 32 participants, mean age = 84.7 years, 12 women). MethodsTwo raters used the validated Falls Video Analysis Questionnaire, adapted from the original version, to assess the causal, behavioral, and environmental aspects of falls from wheelchairs. ResultsA total of 58 wheelchair fall videos were identified out of 300 total videos that were collected from 2007 to 2014. Wheelchair falls were most often caused by incorrect transfer or shift of body weight (70.7%). Participants most often fell backward with 89.7% striking their pelvis. Individuals using wheelchairs had limited protective response, with only 10.3% demonstrating a step response. Improper brake position contributed to 67.2% of falls. No serious fall-related injuries were reported. Conclusions and ImplicationsThe findings highlight the unique nature of falls in older adults who use wheelchairs in long-term care settings. Overall, the results of this study support clinical practice and the critical need for developing specialized fall prevention and fall detection interventions for individuals who use wheelchairs in long-term care.

Fostering social cohesion in ethnolinguistic communities through mother tongue-based initiatives in Nepal

In Nepal and other regions, fostering social cohesion within ethnolinguistic communities is recognized as a vital factor for fostering social prosperity. This research paper presents an integrated framework developed through an extensive literature survey, incorporating the perspectives of ethnolinguistics and social cohesion. The study examines social cohesion using mixed methods, exploring its domains and correlation with linguistic theories. Special attention is given to the role of social prosperity and how this study impacts attitudinal and behavioral aspects of social cohesion. The study’s findings underscore the significance of interconnected social relations, a sense of connectedness, and shared common goods as essential elements for fostering practical social harmony. Notably, the research emphasizes the critical role of mother tongue-based educational activities in empowering ethnolinguistic communities, catalyzing sociocultural transformation, and promoting identity. It is revealed that these initiatives contribute to poverty reduction and foster gender equality and social inclusion. Moreover, the research advocates language-based interventions as a pivotal strategy for enhancing social cohesion. By recognizing language as a critical element that binds communities, this study aims to create a more fruitful investigation and provide practical, scientific, and managerial contributions in fostering social cohesion within ethnolinguistic contexts.

Development of the Binocular Circuit.

Seeing in three dimensions is a major property of the visual system in mammals. The circuit underlying this property begins in the retina, from which retinal ganglion cells (RGCs) extend to the same or opposite side of the brain. RGC axons decussate to form the optic chiasm, then grow to targets in the thalamus and midbrain, where they synapse with neurons that project to the visual cortex. Here we review the cellular and molecular mechanisms of RGC axonal growth cone guidance across or away from the midline via receptors to cues in the midline environment. We present new views on the specification of ipsi- and contralateral RGC subpopulations and factors implementing their organization in the optic tract and termination in subregions of their targets. Lastly, we describe the functional and behavioral aspects of binocular vision, focusing on the mouse, and discuss recent discoveries on the evolution of the binocular circuit.

FamilyScope: Visualizing Affective Aspects of Family Social Interactions using Passive Sensor Data

This work presents FamilyScope, a sensor-based family informatics system that enables reflection upon family data collected from family activity scenarios (e.g., game playing and movie watching) that include affective aspects of a family's social interactions. We conducted a user study with ten families (n=30) in a smart home testbed to observe how our system supports data reflection of the affective and behavioral states among family members. Our findings showed that FamilyScope facilitated family data reflection on affective and behavioral aspects of family interactions. Overall, families reported that the system well reflected family members' general tendencies in terms of affective and behavioral responses and even helped them gain new insights about each other. Based on the findings, we provide practical design approaches for collective reflection in family informatics systems.

A macro-level analysis of the socio-economic impacts of climate change driven water scarcity: Incorporating behavioural and resilience aspects

Recognising the urgent need to address water scarcity resulting from climate change, there is a growing push to enhance the resilience of water (and related) systems. For instance, policymakers are now urging companies to shift from short-term focused strategies towards long-term approaches to effectively manage water scarcity. This paper utilises a custom-built dynamic multisectoral model to assess the socio-economic impacts at a macro-level of temporary water scarcity. The focus of the analysis is to identify the effects that varying levels of investment foresight may have on economic resilience. Specifically, the model incorporates often overlooked factors such as behavioural and resilience aspects. By considering these key elements, a more comprehensive understanding of the system-wide implications of water scarcity on the broader economy is provided. The analysis shows how firms' foresight, or lack thereof, impacts their response to water scarcity and the subsequent impact on the economy. Sector-specific analyses shed light on the potential negative impacts of water scarcity on sectors like agriculture, food, and electricity production and distribution. Yet, the analysis also reveals that certain sectors can benefit from competitiveness effects, which can mitigate the adverse economic implications of water scarcity. However, it should be noted that these sectors may contribute to a catch-up effect on water use. The policy recommendations arising from this research emphasise the promotion of anticipation and preparedness among firms. It is crucial to prioritise resilience-building measures in all sectors, whether they directly rely on water or not.

Do They Know What They Are Doing? Cognitive Aspects of Rescue Behaviour Directed by Workers of the Red Wood Ant Formica polyctena to Nestmate Victims Entrapped in Artificial Snares.

Ant rescue behaviour belongs to the most interesting subcategories of prosocial and altruistic behaviour encountered in the animal world. Several studies suggested that ants are able to identify what exactly restrains the movements of another individual and to direct their rescue behaviour precisely to that object. To shed more light on the question of how precise the identification of the source of restraint of another ant is, we investigated rescue behaviour of red wood ant Formica polyctena workers, using a new version of an artificial snare bioassay in which a nestmate victim bore two wire loops on its body, one (acting as a snare) placed on its petiole and an additional one on its leg. The tested ants did not preferentially direct their rescue behaviour towards the snare. Moreover, the overall strategy adopted by the most active rescuers was not limited to precisely targeted rescue attempts directed towards the snare, but consisted of frequent switching between various subcategories of rescue behaviour. These findings highlight the importance of precise identification of cognitive processes and overall behavioural strategies for better understanding of causal factors underlying animal helping behaviour in light of new facts discovered by testing of various successive research hypotheses.

Brain oscillations during emotion regulation and the two-dimensional model of adult attachment

Emotion Regulation (ER) refers to the processes by which individuals influence their own emotions. It is a crucial aspect of human behavior, affecting everything from interpersonal relationships to mental health. The relationship between ER and Attachment Theory (AT) is pivotal. AT suggests that early bonds with primary caregivers influence future relationship expectations and behaviors. These initial experiences shape internal models of self and others, affecting how individuals regulate their emotions. Understanding the interplay between ER and AT is essential for comprehending the human affective system. In this study, we explored the neural underpinnings of ER, focusing on two distinct strategies: cognitive reappraisal and expressive suppression. Using electroencephalography (EEG), we examined changes in neural oscillations from 52 adults during an ER task. Specifically, we observed increased frontal theta activity (3–6 Hz) during reappraisal compared to suppression strategies. This frontal theta activity suggests enhanced cognitive control engagement. Conversely, during suppression, we noted a decrease in beta frequency (15–30 Hz) activity from central electrodes, indicative of differing neural processes. Further integrating psychological theories, we explored the relationship between these neural markers and dimensions of human attachment. Employing the Experiences in Close Relationships-12 scale (ECR-12), we identified a negative correlation between attachment anxiety and frontal theta activity. Lower levels of attachment anxiety were associated with increased theta activity, reflecting potentially more effective emotion regulation. Additionally, we found that higher theta activity corresponded with fewer difficulties in emotional control measured by the Difficulties in Emotion Regulation Scale (DERS). Regarding central beta activity, our findings revealed an interesting correlation with Emotional Inattention, a concept tied to Attachment Avoidance. This suggests that central beta activity may serve as a neural marker for specific attachment-related ER processing. These results highlight the distinct neural pathways involved in different ER strategies and their relationship with the AT and neural responses during emotional processing.

Wasted Food, Wasted Resources? A Critical Review of Environmental Impact Analysis of Food Loss and Waste Generation and Treatment.

Food loss and waste (FLW) comes with significant environmental impacts and thus prevents a sustainable food system transition. Here we conducted a systematic review of 174 screened studies that assessed the environmental impacts of FLW generation and treatment. We found that the embodied impacts of FLW along the supply chain and impacts from FLW treatment received equal attention, but few studies have included both. The reviewed studies show narrow geographical (mostly conducted in industrialized countries) and food supply chain (mostly focused on the consumption stage) coverage. Life cycle analysis (LCA), material flow analysis (MFA), or their combination are the most commonly used to quantify FLW related environmental impacts. More method standardization, integration, and innovation and better FLW data with regional and stage resolution from a first-hand source are badly needed. Among the various proposed mitigation strategies covering technology, economy, behavior, and policy aspects, process optimization and waste management options are the most discussed. Our review calls for a more holistic environmental impact assessment of FLW generation and treatment and analysis of the trade-offs among different environmental impact categories and between supply chain stages, which would better inform relevant policy on effective environmental impact mitigation strategies toward sustainable food systems.
