Darwin explored the evolutionary processes underlying artistic propensities in humans. He stressed the universality of the human mind by pointing to the shared pleasure which all populations take in dancing, engaging in music, acting, painting, tattooing, and self-decorating. Artistic motivation drives/reinforces individuals to engage in aesthetically oriented activities. As curiosity/play, artistic behavior is hypothesized as a functionally autonomous activity motivated intrinsically through an evolved, specific, and stable aesthetic motivational system. The author tested whether artistic motivation is rather intrinsically sourced, domain-specific, and temporally stable using a large decades-long real-life public Brazilian database of university applications. In Study I, the author analyzed reasons for career-choice responded to by 403,832 late-adolescent applicants (48.84% women), between 1987 and 1998. In Study II, the author analyzed another career-choice reason question responded to by 1,703,916 late-adolescent applicants (51.02% women), between 1987 and 2020. Music, Dance, Scenic Arts, Visual Arts, and Literary Studies, in combination, presented a higher percentage of individuals reporting intrinsic factors (e.g., personal taste/aptitude/fulfillment) and the lower proportion reporting extrinsic motives (e.g., the influence of media/teacher/family, salary, social contribution/prestige) than other career groups. If artistic motivation were a recent by-product of general curiosity or status-seeking, artistic and non-artistic careers would not differ. Overall, intrinsic motives were 2.60–6.35 times higher than extrinsic factors; among artistic applicants’ were 10.81–28.38 times higher, suggesting domain-specificity. Intrinsic motivation did not differ among artistic careers and remained stable throughout the periods. Converging results corroborated a specific, stable, and intrinsically sourced artistic motivation consistent with its possible evolutionary origins.

Why females choose a career path is a stimulating question among social educators. Consequently, this study investigated the role of some intrinsic, extrinsic, and interpersonal variables in shaping the choice of career of female undergraduates. An Online Career Choice Survey questionnaire was administered to 1440 first to fifth-year female undergraduates randomly selected from Obafemi Awolowo University. Data obtained were subjected to ordinal logistic regression and descriptive analysis. Two intrinsic factors; prestige and personal interest were found to play a huge role in the choice of career. Among extrinsic factors, females were more likely to choose a career path that offers career advancement through training. Gender stereotypes and societal expectations as pro-jected by the media was a key interpersonal factor that could shape present-day career paths for young women. Taken together, these results bring forth the need for stakeholders in the educational system (teachers, counselors, principals) to provide career and professional development opportu-nities periodically to enable female students to make informed career decisions. Finally, given the huge influence of media in shaping future aspirations, there is a dire need for the media to portray women in traditionally male-dominated careers.

From the intentionality-based view, individuals' actual behaviors to initiate a new venture is driven by their entrepreneurial intentions. Company employees have accumulated professionalism and practical experience, which both enable them to discover some unmet market demand and industrial gaps. However, in establishing a new business, not everyone with certain knowledge or expertise has the desire to become an entrepreneur. Prior research has shown that entrepreneurial intentions are under the profound influences of intrinsic factors and extrinsic factors. On the one hand, entrepreneurial self-efficacy is one of the key psychological states that makes someone dare to initiate entrepreneurial activities. Institutional environment, on the other hand, can either enhance and hinder an individuals' entrepreneurial motivation by offering incentives or causing barriers. Little work has been done to understand how the institutional environment and entrepreneurial self-efficacy jointly affect company employees' intention to quit their job and start an enterprising career. By using hierarchical regression on a sample of 325 Indonesian company employees, this paper shows that the entrepreneurial cognition and entrepreneurial self-efficacy are positively related to employees' entrepreneurial intentions. Also, entrepreneurial self-efficacy strengthens the effect of normative Approval on entrepreneurial intention, whereas the regulatory Support from Government is detrimental to company employees' intention to start a new venture regardless the entrepreneurial self-efficacy is high or low.

High-quality lighting positively influences visual performance in humans. The experienced visual performance can be measured using desktop luminance and hence several lighting control systems have been developed for its quantification. However, the measurement devices that are used to monitor the desktop luminance in existing lighting control systems are obtrusive to the users. As an alternative, ceiling-based luminance projection sensors are being used recently as these are unobtrusive and can capture the direct task area of a user. The positioning of these devices on the ceiling requires to estimate the desktop luminance in the user's vertical visual field, solely using ceiling-based measurements, to better predict the experienced visual performance of the user. For this purpose, we present LUMNET, an approach for estimating desktop luminance with deep models through utilizing supervised and self-supervised learning. Our model learns visual representations from ceiling-based images, which are collected in indoor spaces within the physical vicinity of the user to predict average desktop luminance as experienced in a real-life setting. We also propose a self-supervised contrastive method for pre-training LUMNET with unlabeled data and we demonstrate that the learned features are transferable onto a small labeled dataset which minimizes the requirement of costly data annotations. Likewise, we perform experiments on domain-specific datasets and show that our approach significantly improves over the baseline results from prior methods in estimating luminance, particularly in the low-data regime. LUMNET is an important step towards learning-based technique for luminance estimation and can be used for adaptive lighting control directly on-device thanks to its minimal computational footprint with an added benefit of preserving user's privacy.

AbstractMosquitoes are emerging as model systems with which to study innate behaviours through neuroethology and functional genomics. Decades of work on these disease vectors have provided a solid behavioural framework describing the distinct repertoire of predominantly odour-mediated behaviours of female mosquitoes, and their dependence on life stage (intrinsic factors) and environmental cues (extrinsic factors). The purpose of this review is to provide an overview of how intrinsic factors, including adult maturation, age, nutritional status, and infection, affect the attraction to plants and feeding on plant fluids, host seeking, blood feeding, supplemental feeding behaviours, pre-oviposition behaviour, and oviposition in female mosquitoes. With the technological advancements in the recent two decades, we have gained a better understanding of which volatile organic compounds are used by mosquitoes to recognise and discriminate among various fitness-enhancing resources, and characterised their neural and molecular correlates. In this review, we present the state of the art of the peripheral olfactory system as described by the neural physiology, functional genomics, and genetics underlying the demonstrated changes in the behavioural repertoire in female mosquitoes. The review is meant as a summary introduction to the current conceptual thinking in the field.

Roads are notable and responsible for the loss of biodiversity and disruption of wildlife habitats connectivity. Wildlife crossing structures (WCS) help wildlife move between habitats by connecting fragmented habitats. Their effectiveness is affected by various factors. Here, to identify methods for improving the effectiveness of wildlife crossing structures, we controlled the effect of intrinsic factors, such as size, that are difficult to improve in an already installed area, and then, evaluated the differences in extrinsic factors using 12 landscape characteristics. Our results show that 18 wildlife crossing structures were selected with propensity-score (PS) matching method. The surrounding landscape characteristics differed between high-effectiveness wildlife crossing structures and low-effectiveness wildlife crossing structures. Particularly, there was a significant difference between the ‘statutory protected area’ and the ‘edge’ index of the morphological spatial pattern analysis among the landscape characteristic variables derived within 1 km2 of wildlife crossing structures. We empirically demonstrate that characteristics around highly effective WCS, statutory protected areas are widely distributed, and the ratio of edge of MSPA is low (within 1 km2). Therefore, an important outcome of our research is the demonstration that management of WCS itself is important, but conservation of surrounding habitats and landscape management plans are also significant.

Activity levels and foraging success of ectotherms are dependent both on extrinsic factors (e.g., ambient temperature) and intrinsic factors (e.g., hunger level). We focus here on activity and foraging of sand vipers ( Cerastes vipera (L., 1758)) (Squamata: Viperidae) in the northwestern Negev desert of Israel. Viper activity is bounded by a specific thermal range, but within this range, temperature does not affect the distance moved. Movement distances are, however, positively correlated with relative humidity. The capture success of lizards, the main prey of this viper, is strongly related both to movement distances of the snake and to the number of the lizard burrows scanned. Body size and shape have a direct effect on the number of burrows scanned and on the number of lizards captured. The increase in capture success with size is probably due to the consequent increase in the range of prey items the sand viper can subdue or handle. Vipers are larger and have a higher mass to length ratio in one of the three study sites, characterized by higher mean annual rainfall and vegetation cover. Finally, females tend to have a higher mass to length ratio than males, which may provide some space within the female body for reproductive materials such as eggs.

AbstractIn many species, the ability to defend a territory is essential for a male to obtain any reproductive success at all, and even among territorial individuals, variation in the strength of territory defense could have a significant impact on how much reproductive success is obtained. Previous studies have documented consistent individual differences in the vigor with which male song sparrows (Melospiza melodia) defend their territories, as measured by the strength of their reactions to territorial intrusions simulated through song playback. Variation in the strength of defense could reflect intrinsic differences among individuals in their resource holding potential (RHP), or variation in extrinsic factors. In this study, we examined whether variation in the strength of territory defense corresponds to differences in intrinsic factors such as the age or experience of the territory owner, the extrinsic factor of the level of aggression shown by neighbours, or both. Results indicate that males that previously held territories on the study site, regardless of whether they were holding the same territory as the previous year, show higher levels of territory defense than males that are new to the study site, and, assuming that returning males are older males, suggest that age is more important than experience on a specific territory in determining strength of territory defense. In addition, we found evidence that males with high levels of territorial aggression tend to be spatially clustered. The pattern observed suggests that a combination of intrinsic and extrinsic factors contribute to the expression of individual differences in territorial aggression.

The defining characteristic of neural stem cells (NSCs) is their ability to multiply through symmetric divisions and proliferation, and differentiation by asymmetric divisions, thus giving rise to different types of cells of the central nervous system (CNS). A strict temporal space control of the NSC differentiation is necessary, because its alterations are associated with neurological dysfunctions and, in some cases, death. This work reviews the current state of the molecular mechanisms that regulate the transcription in NSCs, organized according to whether the origin of the stimulus that triggers the molecular cascade in the CNS is internal (intrinsic factors) or whether it is the result of the microenvironment that surrounds the CNS (extrinsic factors).

Introduction:In recent decades, job strategies are moving forward to motivate employees. Most organizations have tried to use these strategies to improve their efficiency and optimize their resources. For the success of an organization, prominent employees are very important. The purpose of this study was to investigate the internal and external factors of job motivation among employees of health network of Kuhdasht city. Materials and methods: The study was descriptive-analytic and cross-sectional.The statistical population consisted of the healthcare network staff. 309 employees were selected through systematic random sampling. To gather information, the Herzberg questionnaire was used which included the variables of the Intrinsic and extrinsic factors of job motivation.Demographic factors were investigated.Data were analyzed by SPSS software version 20 and Pearson and Spearman correlation, independent t tests and one-way analysis of variance. Findings:The average score of the Intrinsic factors of the job motivation was 56.02 and the standard deviation was 9.4 and the mean score of the extrinsic factors of the job motivation was 80.4 with a standard deviation of 9.02.The average score of extrinsic factors was higher than the external ones. Among the Intrinsic factors, the average score of knowledge and appreciation was higher than the rest of the factors, and in the extrinsic factors the relationship between the factors of communicationand the way of supervision was higher than the rest.There was no significant relationship between age, marital status, place of service and type of place of service with Intrinsic and extrinsic factors score and total amount of job motivation. There was a meaningless relationship between the staff record with the Intrinsic factors and the level of education and the extrinsic factors. The average score of Intrinsic factors and the total amount of job motivation in female employees was significantly higher than that of male employees. The average score of Intrinsic factors among employees with different occupational categories was significantly different and in the staff of the health care and health services was significantly more than the administrative-service staffs. The score of the Intrinsic factors and the total amount of job motivation was related to the type of staff recruitment, and in the staff with the contractual employment was significantly less than other employees. Conclusion:Although attention to Intrinsic and extrinsic factors is important for job inductance,but attention to employees' relationships, the way of their supervision and appreciation of them have of great importance in creating job motivation. Key words:Intrinsic factor, extrinsic factors, job motivation, Employees, Health Network

Considering the importance of job satisfaction in teaching, and the ongoing debate regarding the influence of various factors on job satisfaction, this study identifies the status of job satisfaction and examines the influence of institutional sector and demographic factors on job satisfaction among Nepalese academicians. The study sample comprised 156 academicians from different higher-level educational institutions in Nepal, and the data were collected through structured questionnaires. Descriptive statistics, independent-samples t-test, and one-way ANOVA test were used to analyze the data. Results showed that Nepalese academicians are moderately satisfied with their job, in which intrinsic factors appear stronger than extrinsic factors. The findings also demonstrated that the institutional sector, in favor of public institutions, and academic qualification influence job satisfaction but gender, age, and teaching experience do not influence job satisfaction of academicians. Widespread sampling framework, all-inclusive job satisfaction measures, and remarkable findings have made the study unique and potent.
