Evidence of differential genetic introgression at multiple localities between Neotoma floridana and N. micropus

To determine the extent of genetic introgression along the parapatric border between Neotoma floridana and N. micropus, 140 woodrats were sampled from 21 localities in Kansas, Oklahoma, and Texas, at varying distances from the proposed species boundaries. All individuals were examined at the mitochondrial cytochrome-b gene (Cytb) and two nuclear introns: intron seven of the Beta fibrinogen gene (Fgb-I7) and intron 2 of the vertebrate alcohol dehydrogenase gene (Adh1-I2). Additionally, individuals from a putative contact zone were genotyped using six microsatellite loci to better analyze population structure. Evidence of mixed ancestry was detected in 55 of 140 (39 %) individuals, at 10 of 21 (48 %) localities up to ~150 km from the proposed parapatric boundary. A pattern of differential admixture detected between the two nuclear markers suggested variation in selection pressures at the Adh1-I2 and Fgb-I7 markers is dependent upon the genomic makeup of the individual. Together, the mitochondrial and nuclear markers indicate evidence of historical hybridization and suggest that hybrid zones within this system are transient in nature.
Entrepreneurship in social: Brazilian university students toward a career with purpose

Purpose Social entrepreneurship (SE) presents specificities that the entrepreneur must address. Entrepreneurial intention (EI) and entrepreneurial orientation (EO) in SE should reflect specific characteristics of behavior. The purpose of this study is to identify the intention of Brazilian university students to undertake SE, having individual social EO (individual entrepreneurial orientation (IEO)-social) as their predictive behavior. Design/methodology/approach This paper collected study data from Brazilian university students. To test the study’s hypotheses, this paper used confirmatory factor analysis, structural equation model, partial least squares and generalized linear regression model. Findings The results indicate that Brazilian university students positively respond to their intention to become social entrepreneurs in the future, regardless of gender, courses or types of universities. In line with the literature, IEO-Social proved to be a strong predictor of EI-social. Research limitations/implications This study was limited to understanding EI-social from IEO-Social. Besides, its sample is non-probabilistic, therefore, the findings of this study cannot be generalized. Practical implications The results encourage the inclusion of SE in entrepreneurial education programs. They guide the involvement of students from different areas of knowledge in activities aimed at higher education. Social implications Evidence indicates that including the SE theme in entrepreneurial education programs proves to be valuable for opening purposeful career opportunities for students. Originality/value The study contributes to eliminating the gap in studies on EI-social in Brazilian university students. It also offers the IEO-social scale, theoretically constructed and with superior psychometric quality.
Non-identifiability and testability of missing mechanisms in incomplete two-way contingency tables

We showed that any missing mechanism is reproduced by EMAR or MNAR with equal fit for observed likelihood if there are non-negative solutions of maximum likelihood equations. This is a generalization of Molenberghs et al. (2008) and Jeon et al. (2019). Nonetheless, as MCAR becomes a nested model of MNAR, a natural question is whether or not MNAR and MCAR are testable by using the well-known three statistics, LR (Likelihood ratio), Wald, and Score test statistics. Through simulation studies, we compared these three statistics. We investigated to what extent the boundary solution affect tesing MCAR against MNAR, which is the only testable pair of missing mechanisms based on observed likelihood. We showed that all three statistics are useful as long as the boundary proximity is far from 1.
OH (super -) in pyroxene; an experimental study of incorporation mechanisms and stability

Most pyroxenes contain trace amounts of OH^- that are lost when heated at 700 °C (1atm) under either air or H_2. When Si-deficient Fe^(3+) -rich pyroxenes (ferrian diopside and esseneite) are heated in H_2, an up to 70-fold increase of the intensity of the infrared OH absorption bands occurs, which is well correlated with Si deficiency in the tetrahedral site. Mossbauer and optical spectroscopy indicate that these samples have substantial amounts of Fe^(3+) in the tetrahedral position. After the uptake of H_2, optical spectra show that the amount of Fe^(2+) in the M(2) site has increased, corresponding to charge compensation according to the reaction Fe^(3+)O^(2-) + 1/2H_2 = Fe^(2+) + OH^-. Heating in air at 600-700 °C decreases or removes the OH^- bands. The OH^- bands from air-heated samples are restored by subsequent heating in H_2. Hydrothermal experiments (600 to 800 °C and Ito 2-kbar H_2O pressure) do not increase the amount of OH^- but do redistribute some of the absorption intensity among the OH^- bands. Experiments performed in D_2O show that OD^- readily replaces OH^-. Therefore the diffusion of H^+ through the pyroxene crystal cannot be a rate-limiting process, and hence a more fundamental change than just a mechanical introduction is required to incorporate OH^- in the pyroxene structure. The thermal stability of the OH^- in pyroxene is comparable to OH^- in Fe-rich amphiboles and suggests that pyroxenes can provide information about the activity of hydrous components prevalent during their crystallization.
Using Individualised HDI Measures for Predicting Educational Performance of Young Students—A Swedish Case Study

HDI is a frequently used quantitative index of human potential and welfare, developed as a comprehensive measure for the cross-sectional and temporal comparison of socioeconomic performance. The HDI is a standardised quantitative estimation of welfare comprising indicators of health, knowledge and standard of living, enabling assessment over countries, regions or time periods, in case of limited data access. The index highlights critical conditions for equity and socioeconomic development outside the group of stakeholders and researchers. The HDI provides a learning potential that may be harnessed to enhance insights into the magnitude of human potential at super-local levels. In this paper we design, implement and test the validity of a super-local variant of HDI in the context of pedagogical performance of young pupils. We compare whether HDI is a good predictor for school grades among all ninth-grade students in Sweden during the year 2014. Our results show that a super-local HDI index is performing equal to or better than the one related to standard measures of human potential, while the index can be generated on individual levels using k-nearest neighbour approaches during the index creation process.
Preparation and Assessment of Some Characteristics of Nanoparticles Based on Sodium Alginate, Chitosan, and Camellia chrysantha Polyphenols

This paper presents the characteristics, morphology, and properties of alginate/chitosan/polyphenol nanoparticles, in which polyphenols were extracted from Camellia chrysantha leaves collected in Tam Dao district, Vinh Phuc province (Vietnam). The alginate/chitosan/polyphenol nanoparticles were prepared by ionic gelation method at different polyphenol content. The characteristics and morphology of these nanoparticles were investigated using infrared spectroscopy (IR), ultraviolet-visible spectroscopy (UV-Vis), and scanning electron microscopy (SEM). Release kinetic of polyphenols from the alginate/chitosan/polyphenol nanoparticles was conducted in simulated human body fluids. The release kinetics of polyphenols from the above nanoparticles were also evaluated and discussed. The experimental results showed that the release process of polyphenols from the nanoparticles was dependent on three factors: time, pH of solution, and amount of polyphenols.
The Potential Of Internationalization Of Small And Medium Micro Enterprises In SAWO Leather Crafts, Magetan District, East Java, Indonesia

The Magetan leather handicraft business is one of the long-established and surviving SMEs and contributes to the creation of employment and income for the community. Currently, the marketing of leather handicraft products is still limited to meeting local and national needs so that limited market demand makes leather handicraft difficult to develop. Globalization and increasingly advanced information technology have become opportunities for the Magetanleathercraft industry to penetrate the international market, however, various obstacles arise considering that penetrating the global market is not easy for small businesses that have many limitations. The purpose of this case study is to examine the opportunities and obstacles of the Magetan leather handicraft business to penetrate the international market. This research approach is qualitative with case studies.owner of leather handicraft, owner of leathercraft marketing shop, the buyer of leathercraft, an employee of leathercraft. Data analysis includes (1) data collection (2) data display (3) data reduction and (4) conclusions. [1]The results showed that there were obstacles to the internationalization of the Magetan leather handicraft business, namely complicated international trade procedures for SMEs, No marketing channels abroad for SMEs, Limited SME resources. The solution that can be offered from this problem is not to let SMEs directly penetrate the global market independently given the limitations they have, but by providing a mediator that can bridge SMEs with foreign consumers with a Marketplace, Exporters, or Cooperatives.
Effect of dietary tannins on the performance, lymphoid organ weight, and amino acid ileal digestibility of broiler chickens: A meta-analysis

Background and Aim: Tannins are functional secondary metabolites that may provide benefits to ruminants. However, to date, their effects on broiler chickens remain inconclusive. This study aimed to evaluate the effectiveness of dietary tannin levels on the performance, body organs, and amino acid (AA) digestibility of broiler chickens using a meta-analysis. Materials and Methods: After verification and evaluation, a total of 22 articles were included in the present study. All data regarding dietary tannin dosages, performance, digestibility, and gastrointestinal physiology of broiler chickens were tabulated into a database. The database data were then statistically analyzed using mixed models, with tannin dose as a fixed effect and study as a random effect. Results: High levels of dietary tannins negatively affected the average daily gain and average daily feed intake of broiler chickens according to linear patterns (p<0.001). In addition, dietary tannins decreased drumstick and liver weights, as well as bursa of Fabricius and spleen weight (p<0.05). Meanwhile, other carcass traits (i.e., thigh, wings, and body fat) were not influenced by dietary tannins. Regarding AA digestibility, high dietary tannin concentrations induced negative responses on isoleucine, leucine, and methionine digestibility (p<0.05). Conclusion: Dietary tannins appear to have a negative effect on broiler performance, lymphoid organ weight, and AA ileal digestibility. Hence, the addition of tannins to broiler diets is not recommended.
Treated Wastewater Irrigation—A Review

As the most important resource for life, water has been a central issue on the international agenda for several decades. Yet, the world’s supply of clean freshwater is steadily decreasing due to extensive agricultural demand for irrigated lands. Therefore, water resources should be used with greater efficiency, and the use of non-traditional water resources, such as Treated Wastewater (TW), should be increased. Reusing TW could be an alternative option to increase water resources. Thus, many countries have decided to turn wastewater into an irrigation resource to help meet urban demand and address water shortages. However, because of the nature of that water, there are potential problems associated with its use in irrigation. Some of the major concerns are health hazards, salinity build-up, and toxicity hazards. The objectives of this comprehensive literature review are to illuminate the importance of using TW in irrigation as an alternative freshwater source and to assess the effects of its use on soil fertility and other soil properties, plants, and public health. The literature review reveals that TW reuse has become part of the extension program for boosting water resource utilization. However, the uncontrolled application of such waters has many unfavorable effects on both soils and plants, especially in the long-term. To reduce these unfavorable effects when using TW in irrigation, proper guidelines for wastewater reuse and management should be followed to limit negative effects significantly.
A geodesic deployment and radial shaped clustering (RSC) algorithm with statistical aggregation in sensor networks

: Wireless sensor networks (WSN) comprise a large number of connected tiny or small sensor devices to sense physical phenomenon. In WSN, prolonging the network’s lifetime is a biggest challenge due to absence of power harvesting facility and irreplaceable batteries of the sensor devices. Clustering is one of the widely accepted and standard technique to solve the energy issues faced in WSN. In addition to clustering, the shape of the deployment area also plays the major role especially for large scale sensor deployment. This paper proposes a radial shaped clustering (RSC) algorithm with angular inclination routing. The radial shaped deployed area is divided into virtual concentric layers and each layer is further divided into a set of sectors called clusters. Angular routing is applied to achieve multihop routing of packets towards the Sink node. In comparison to fan shaped clustering (FSC), RSC performs better in terms of residual energy and packet received ratio.
Deep Learning Model Based on Mobile-Net with Haar-like Algorithm for Masked Face Recognition at Nuclear Facilities

During the spread of the COVID-I9 pandemic in early 2020, the WHO organization advised all people in the world to wear face-mask to limit the spread of COVID-19. Many facilities required that their employees wear face-mask. For the safety of the facility, it was mandatory to recognize the identity of the individual wearing the mask. Hence, face recognition of the masked individuals was required. In this research, a novel technique is proposed based on a mobile-net and Haar-like algorithm for detecting and recognizing the masked face. Firstly, recognize the authorized person that enters the nuclear facility in case of wearing the masked-face using mobile-net. Secondly, applying Haar-like features to detect the retina of the person to extract the boundary box around the retina compares this with the dataset of the person without the mask for recognition. The results of the proposed modal, which was tested on a dataset from Kaggle, yielded 0.99 accuracies, a loss of 0.08, F1.score 0.98.
Impact of COVID-19 on Sustainable University Sports: Analysis of Physical Activity and Positive and Negative Affects in Athletes

The suspension of university activities due to the pandemic affected training and sports competitions. However, some universities adapted online education, allowing students to carry out their activities without being infected by the virus. The aim of this study was to find out the impact of the pandemic on physical activity levels and the positive and negative effects on Chilean university athletes. The information was obtained by applying the PANAS scale and demographic and physical activity variables were also measured. The sample of Chilean university athletes (n = 254) were aged between 18 and 31 years (M = 22.17; SD = 2.76). This study led to the conclusion that maintaining the frequency of physical training during the pandemic was associated with a preservation in the levels of Positive Affect and Negative Affect compared to the non-pandemic period. Thus, physical activity training was protective of emotional well-being and, therefore, of mental health.
TURNOVER INTENTION AMONG LECTURERS IN PRIVATE HIGHER EDUCATION: THE DIRECT IMPACT OF FINANCIAL REWARDS AND MEDIATION OF JOB SATISFACTION AND EFFECTIVE ORGANIZATIONAL COMMITMENT

Lecturer responsibilities in presenting learning materials and building students’ character is considered very important in preparing future workers/entrepreneur. However, those responsibilities still have not received proper attention in certain institutions and even from the government. If this goes on continuously, it is feared that they will lose wellperformed individuals. This study aimed to investigate the level of turnover intention from the lecturer in six private universities in Bandung. And the role of financial rewards, job satisfaction, and affective organizational commitment as antecedents. Data collected using an online questionnaire. The numbers of total lecturers in those universities were around 3000. This study used a non-probability sample and distributed 500 questionnaires through the human resources office. And after two months, there are 288 participants which willing to complete the questionnaire. After the more detailed screening, we have 121 responses that met our requirements and can be used in this study. The study found that financial rewards were significantly affected job satisfaction and affective organizational commitment. But it was not significantly affected turnover intention. Partially, job satisfaction and affective commitment have not mediated the relationship between financial rewards and turnover intention. But, simultaneously, both variables have significantly mediated the relationship. These results give new understanding to the managers in the educational organization regarding maintaining the turnover level of their lecturers. In the future, studies can be conducted to cover lecturers from other cities in Indonesia.
Satisfaction With Dwelling Unit Attributes and Infrastructure Within Selected Public Housing Estates in Northern Nigeria

This study assessed satisfaction with dwelling unit attributes as well as support services and infrastructure within public housing estates across Northern Nigeria as such studies are rare in literature but important for design and policymaking. Results of descriptive statistics, Principal Component Analyses and Regression from 125 respondents in Abuja, Dutse, Sokoto, Gombe and Potiskum revealed that support services and infrastructure notably water supply and waste disposal were inadequate. Although residents were fairly satisfied with their dwelling units (M 3.13), water supply influenced satisfaction ratings for service-related spaces including baths, toilets, cooking and storage. Other areas of dissatisfaction were number of bedrooms, quality of construction and sizes of living spaces. Residents were most satisfied with quality of natural lighting, ventilation, location of houses, noise as well as privacy levels. Results from PCA revealed that residents view satisfaction with their dwelling unit attributes and infrastructure in terms of design and cost, services and indoor environmental quality as well as electricity supply and noise levels. These three factors emerged as significant predictors of satisfaction with dwelling unit attributes and infrastructure, F (20.54, 18), p=0.000, R 2 =0.777, in a model that included tenant characteristics. Findings imply that inadequacy in water supply requires urgent attention within public housing estates in the region. Importantly, user perception in terms of the three predictors of satisfaction ought to guide design of future dwelling units within public housing estates in Northern Nigeria.
The broadening boundaries of materialism

The implications of waning desire for ownership on materialism are not well understood. This study examines the interface between materialism and consumption and asks, is materialism manifest in the absence of ownership centrality, and if so, how? Drawing from an interpretive investigation of digital nomads, it is suggested that materialism has broadened to adapt to non-ownership centrality, and we define it as a logic of consumption, which manifests as a preoccupation with the consumption of objects, access or experiences as a way to signal status, build image, pursue happiness, and attain a sense of self-worth. Three discrete but complementary ways through which materialism emerges in the absence of ownership centrality are identified: (1) preoccupation with strategic curation rather than accumulation, (2) intentional prioritization of experiential consumption over ownership as a means to fulfill materialistic aims, and (3) adoption of bricolages across spectrums of consumption (solid/liquid, budget/luxury, access/ownership).
Children as courseware collaborators: Using participatory research to produce courseware integrating science and sustainable development

UNESCO’s 2014 report on education for sustainable development (ESD), Shaping the Future We Want, shows that there have been worldwide advances in integrating ESD into school curriculums. Although there is a global curriculum in ESD, children as the end users of the curriculum are not actively involved in constructing sustainable discourses. Cognisant of children’s role in materials development, this research investigates how teachers can collaborate with children in producing teacher-made courseware using participatory action research (PAR). The study was conducted with 37 teachers enrolled in a graduate course on second-language teaching. Its goal was to produce courseware that promotes ESD and science concepts, such as global warming and the environment. Using PAR, the children collaborated with the teachers in designing the content. Interviews, focus-group discussions and surveys show that the courseware promoted excitement, science and ESD concepts, but suggested revising and trimming some videos and reading texts.
Effects of High-Speed Railway Construction and Operation on Related Industries in China

Incorporated as a highly integrated system of science and technology that has been assimilated in the field of transportation, high-speed railways not only meet the green travel needs of people but also promote the development of correlated industries. Considering the differences in each stage, primarily based on the input-output table for 149 sectors from the Chinese economy taken from the year 2017, an input-output model has been developed and applied in order to measure the economic pull of high-speed railway construction investment for various industries. Moreover, the shift-share spatial structure model has also been taken into account to quantitatively analyze the effect of the high-speed railway operation on related industries, and the three high-speed railway hub cities of Zhengzhou, Xi’an, and Wuhan in China have been taken as the specimens for the application of this model. The results show that the construction and operation of a high-speed railway has an optimization effect on the development of related industries, which provides a basis for industrial layout and structural optimization. This research provides a reference for the formulation of high-speed rail industry policy, is of great significance for the maintenance of sustainable economic development, and thus, promotes the sustainable development of transportation systems, cities and society as a whole.
