Genetic variability, heritability, genetic advance studies in cowpea germplasm [Vigna unguiculata (L.) Walp.]

One hundred and eighty genotypes of cowpea (Vigna unguiculata (L.) Walp) were evaluated during kharif 2017 and thirteen biometrical traits were recorded. Analysis of variance revealed that significant difference existed among the genotypes for all the traits studied. The phenotypic coefficient of variation was higher than genotypic coefficient of variation for all the traits studied. The high estimates of GCV was found in traits viz., number of pods per plant, number of clusters per plant, hundred seed weight and single plant yield. High heritability was observed for plant height, days to 50 per cent of flowering, number of racemes per plant, peduncle length, number of pods per plant, number of clusters per plant, days to maturity, pod length, hundred seed weight and single plant yield. High heritability coupled with high genetic advance as per cent of mean was observed for plant height, number of racemes per plant, peduncle length, number of pods per plant, number of clusters per plant, pod length, hundred seed weight and single plant yield. The high degree of variability was observed among the genotypes for different yield contributing traits. This could be utilised in the breeding programme for the improvement of cowpea.
Critical content knowledges in the English language arts classroom: examining practicing teachers' nuanced perspectives

ABSTRACT Manifest in research, national policy, and instructional standards, the United States has a long-documented interest in teachers as ‘content experts. ’ Yet, research offers limited empirical examinations of teachers’ discipline-specific critical content knowledges—their curricular agility in noticing and disrupting power and oppression, and working to promote empowerment, joy, and liberation. Accordingly, this study asks: what critical content knowledges are most prominent among social justice-oriented secondary English language arts (ELA) teachers, and how do teachers understand and describe these knowledges? Using collective case study methodologies, this study investigates interview data from five ELA teachers to understand participants’ critical content knowledges and their descriptions of these knowledges. Data were interpreted through deductive and inductive coding and analysis. Findings reveal that teachers’ most prominent critical content knowledges include a) knowledge of disciplinary critique; b) knowledge of marginalized identities; and c) knowledge of supplementary content. Limitations to teachers’ critical content knowledges include a narrow race and gender foci, and discursive avoidance of explicitly naming marginalized identities. Implications for future research aimed at better understanding, supporting, and expanding teachers’ critical content knowledges are discussed.
Accuracy Assessment and Correction of SRTM DEM Using ICESat/GLAS Data under Data Coregistration

Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM) inherently suffers from various errors. Many previous works employed Geoscience Laser Altimeter System onboard the Ice, Cloud, and land Elevation Satellite (ICESat/GLAS) data to assess and enhance SRTM DEM accuracy. Nevertheless, data coregistration between the two datasets was commonly neglected in their studies. In this paper, an automated and simple three dimensional (3D) coregistration method (3CM) was introduced to align the 3-arc-second SRTM (SRTM3) DEM and ICESat/GLAS data over Jiangxi province, China. Then, accuracy evaluation of the SRTM3 DEM using ICESat/GLAS data with and without data coregistration was performed on different classes of terrain factors and different land uses, with the purpose of evaluating the importance of data coregistration. Results show that after data coregistration, the root mean square error (RMSE) and mean bias of the SRTM3 DEM are reduced by 14.4% and 97.1%, respectively. Without data coregistration, terrain aspects with a sine-like shape are strongly related to SRTM3 DEM errors; nevertheless, this relationship disappears after data coregistration. Among the six land uses, SRTM3 DEM produces the lowest accuracy in forest areas. Finally, by incorporating land uses, terrain factors and ICESat/GLAS data into the correction models, the SRTM3 DEM was enhanced using multiple linear regression (MLR), back propagation neural network (BPNN), generalized regression NN (GRNN), and random forest (RF), respectively. Results exhibit that the four enhancement models with data coregistration obviously outperform themselves without the coregistration. Among the four models, RF produces the best result, and its RMSE is about 3.1%, 2.7% and 11.3% lower than those of MLR, BPNN, and GRNN, respectively. Moreover, 146 Global Navigation Satellite System (GNSS) points over Ganzhou city of Jiangxi province were used to assess the accuracy of the RF-derived SRTM3 DEM. It is found that the DEM quality is improved and has a similar error magnitude to that relative to the ICESat/GLASS data.
Territorialising homes: Prolonged and return burglaries in South Africa

ABSTRACT This article draws on ethnographic data from South Africa to show that while burglaries may commonly be once-off incidents, many households are repeatedly victimised. In such situations, victims are retargeted and intimidated by the same burglars. Through two exemplary cases of middle- and lower-middle-income households, which are examples of ‘return’ and ‘prolonged’ burglaries, I illustrate that these burglaries are defined by four main characteristics: long duration, the targeted theft of possessions, remaining marks and the close proximity of burglars. I suggest that these burglaries are a way of laying claim to households through symbolic means, rather than physical confrontation. This has lasting social, emotional and financial repercussions for the victims. As relating to repeat-victimisation, burglaries deserve further attention from analysts.
Androgen receptor expression in the urinary bladder urothelial carcinoma and its relation to known prognostic factors

Objective: The current study was carried out to assess the prognostic value of androgen receptor expression in urothelial carcinoma of the bladder and correlate it to the disease outcome. Methods: Histologically confirmed cases of bladder urothelial carcinoma were studied. Clinical, pathological, and radiological data were collected. Paraffin embedded tissue sections were submitted for hematoxylin and eosin staining, as well as immunohistochemical staining for androgen receptor in tumor cells. Results: Nuclear androgen receptor expression was positive in 75% of the studied histopathological specimens. Additionally, a significant positive association between androgen receptor expression and tumor grade, muscle invasion & tumor size were noticed. Conclusions: There is a significant association between large tumor size, high grade, deep invasion, and expression of Androgen receptor in urothelial bladder carcinoma. Antiandrogen could be an effective chemo preventive or therapeutic approach in treatment of urothelial bladder carcinoma.
Determinants of leverage and regulation: an analysis in dental health plan operators

Purpose – This paper examines the determinants of debt levels of Brazilian dental health plan operators (OPS) under the National Supplementary Health Agency (ANS) regulation. Design/methodology/approach – It is an empirical article based on quantitative and causal research. The sample consisted of data from 2010 to 2018 available on the ANS website. The techniques of content analysis, descriptive statistics and panel regression were used for data analysis. Findings – We found that several variables related to the ANS regulation influence dental OPS debt levels. Furthermore, there are also several similarities between the two categories under analysis: dental cooperatives and group dentistry, despite the differences in the legal nature of such organizations. Research limitations/implications – The present study suffers from some limitations: (a) the sample investigated is restricted to OPS public data; and (b) regulation variables are limited due to the data available for calculation, despite our efforts to show otherwise. Originality/value – The present research offers a range of contributions to the literature on dental operators’ capital structure. Firstly, it emphasized the impact of regulation in dental operators’ financial decisions in Brazil. Moreover, it confirmed the important role of companies’ determinant variables of capital structure in explaining OPS debt levels. Lastly, the study introduced regulatory variables as determinants of OPS debt ratios.
A New Method to Handle Conflict when Combining Evidences Using Entropy Function and Evidence Angle with an Effective Application in Fault Diagnosis

Addressing the problem of fusing highly conflicting evidences in Dempster–Shafer theory is one of the most necessary, important, and difficult research directions all the time, and so far we have published two papers related to it. In this paper, another novel method to handle conflict when combining evidences is proposed, where evidence distance, evidence angle, and improved entropy function, three key tools, are used for constructing the final weight of each body of evidence. This newly proposed approach mainly consists of three steps: firstly, both evidence distance and evidence angle determine the initial weight together; secondly, making use of the improved entropy modifies the initial weight to get the final weight; lastly, the classical D-S combination rule will be applied to obtain final fusion results. Still a classical numeric example and a real fault diagnosis application both demonstrate its effectiveness and efficiency, and compared with other current popular methods including two of our previous works, this new approach can converge fast and reduce most uncertainty of decision-making when fusing highly conflicting evidences.
CRISP-R/Cas9 Mediated Deletion of Copper Transport Genes CTR1 and DMT1 in NSCLC Cell Line H1299. Biological and Pharmacological Consequences

Copper, the highly toxic micronutrient, plays two essential roles: it is a catalytic and structural cofactor for Cu-dependent enzymes, and it acts as a secondary messenger. In the cells, copper is imported by CTR1 (high-affinity copper transporter 1), a transmembrane high-affinity copper importer, and DMT1 (divalent metal transporter). In cytosol, enzyme-specific chaperones receive copper from CTR1 C-terminus and deliver it to their apoenzymes. DMT1 cannot be a donor of catalytic copper because it does not have a cytosol domain which is required for copper transfer to the Cu-chaperons that assist the formation of cuproenzymes. Here, we assume that DMT1 can mediate copper way required for a regulatory copper pool. To verify this hypothesis, we used CRISPR/Cas9 to generate H1299 cell line with CTR1 or DMT1 single knockout (KO) and CTR1/DMT1 double knockout (DKO). To confirm KOs of the genes qRT-PCR were used. Two independent clones for each gene were selected for further studies. In CTR1 KO cells, expression of the DMT1 gene was significantly increased and vice versa. In subcellular compartments of the derived cells, copper concentration dropped, however, in nuclei basal level of copper did not change dramatically. CTR1 KO cells, but not DMT1 KO, demonstrated reduced sensitivity to cisplatin and silver ions, the agents that enter the cell through CTR1. Using single CTR1 and DMT1 KO, we were able to show that both, CTR1 and DMT1, provided the formation of vital intracellular cuproenzymes (SOD1, COX), but not secretory ceruloplasmin. The loss of CTR1 resulted in a decrease in the level of COMMD1, XIAP, and NF-κB. Differently, the DMT1 deficiency induced increase of the COMMD1, HIF1α, and XIAP levels. The possibility of using CTR1 KO and DMT1 KO cells to study homeodynamics of catalytic and signaling copper selectively is discussed.
Functional Outcome in Patients with Dural Arteriovenous Fistulae after Surgical Treatment

Spinal dural arterio-venous fistulas (SDAVF) are rare vascular pathologies. Degree of symptom improvement after surgery remains unclear. We evaluated surgically treated SDAVF patients for functional outcome and symptom improvement. Retrospective inclusion of consecutive patients treated surgically in our department between 2007–2019. We measured functional outcome using the McCormick Scale and modified Japanese Orthopaedic Association (mJOA) score. We included 27 patients with a median follow-up of 8.8 months (IQR 27.8). Mean age was 61.8 years (SD 8.4), 40.7% were female. Most frequent location was the thoracic spine in 15 (55.6%) followed by lumbar in 8 (29.6%), cervical in 3 (11.1%) and sacral spine in one patient (3.7%). Most common presenting symptom was progressive myelopathy (24/27 patients, 88.9%). In all patients the SDAVF was completely resected; however, four patients (14.8%) required a second surgery. Six patients (22.2%) deteriorated immediately after surgery with five recovering to baseline upon discharge. On discharge, presenting symptoms had improved in 17 patients (63%); 8/25 patients (32%) had a McCormick score of 1. Twenty (74.1%) continued to improve on follow-up. In total 23/27 patients (85.2%) improved. In the univariable analysis mJOA score on admission was associated with mJOA score on follow-up (coefficient 0.6, 95%CI 0.4–0.81, p < 0.001), whereas age was inversely associated (coefficient −0.1, 95%CI −0.19–0.01, p = 0.08). Untreated SDAVF leads to progressive myelopathy which may result in considerable disability. Surgical disconnection and resection provides a safe treatment option with low perioperative morbidity and excellent chances for symptom improvement or progression prevention.
Labour market polarisation as a localised process: evidence from Sweden

The present article creates a link between contemporary labour market polarisation and regional divergence and analyses the spatial patterns of labour market polarisation in Swedish municipalities during the period 2002–2012. The results show that the national pattern of labour market polarisation is driven by polarisation in clusters of previously manufacturing-dominated municipalities with low- and medium-skill production, as well as increasing labour market polarisation and spatial selection within the fast-growing top-tier metropolitan regions. Outside these polarising spaces, most municipalities still experience job upgrading. The much-discussed abandonment of the traditional Western European job-upgrading model towards a polarising trajectory is thus not unequivocal. Regional labour market change and metropolitan selection cause great variation in labour market trajectories across space.
Trends of Climate Change and Variability in Three Agro-Ecological Settings in Central Ethiopia: Contrasts of Meteorological Data and Farmers’ Perceptions

Using gridded daily temperature and rainfall data covering 30 years (1988–2017), this study investigates trends in rainfall, temperature, and extreme events in three agro-ecological settings in central Ethiopia. The Mann Kendall test and Sen’s slope estimator were used to examine the trends and slope of changes in climate indices. The profile of farmers whose perception converges with or diverges from meteorological data was characterized using polling. The average annual temperature has increased by 0.4 and 0.3 °C per decade in the lowland and midland areas, respectively. Average annual rainfall has increased only in the midland areas by 178 mm per decade. Farmers’ perception of increasing temperature fairly aligns with meteorological data. However, there is a noticeable difference between farmers’ perception of rainfall and meteorological data. The perception of farmers with poor economic status, access to media, and higher social capital aligns with measured trends. Conversely, the perception of economically better-off and uneducated farmers diverges from meteorological data. Accurate perception is constrained by the failure of the traditional forecast methods to describe complex weather variabilities and lack of access to down-scaled weather information. The findings highlight the importance of availing specific and agro-ecologically relevant weather forecasts to overcome perceptual problems and to support effective adaptation.
Optimizing Exercise Selection for the Asymmetric Athlete After Anterior Cruciate Ligament Reconstruction

ABSTRACT Persistent deficits in quadriceps strength occur after anterior cruciate ligament (ACL) reconstruction and should be addressed to facilitate safe return to sport. Asymmetric movement patterns that shield the affected knee by shifting demands to the unaffected lower extremity, or other joints within the affected limb, may limit the ability of common strength training exercises to effectively mitigate quadriceps weakness. A multifaceted approach focusing on the early restoration of symmetrical loading during the squat, programming isolated knee extensions, and varying exercise selection to include split-stance positions, such as the split-squat and lunge, may result in the successful restoration of quadriceps strength after ACL reconstruction.
The fish rots from the head down: a test of the trickle-down model of abusive supervision

A major paradigm shift focusing on the dark side of leadership has generated lots of concern for organizations as leadership has cascading effects on employees’ behaviour. This study aims to understand negative behaviours in the organization as a system of interrelated interaction initiated from the top which trickles down to employees. ,Drawing on the theories of social exchange and norms of reciprocity, social learning and displaced aggression, this study models how and when abusive supervision relates to employees’ task performance. The model is empirically tested and extended to cover mediation and moderation processes. Drawing data from 218 bank supervisors and employees, this study uses the structural equation modelling to analyse a trickle-down model of abusive supervision. ,Results from multi-waved, multi-sourced data indicated a mediating effect on the abusive supervision–performance relationships and provided support for employees’ guilt proneness and emotional dissonance as moderators. Overall, the results provided support for a moderated mediation relationship in the trickle-down model. ,This study provides new knowledge into the potential boundary conditions of employees’ guilt proneness and emotional dissonance in affecting the relationship between abusive supervision, counterproductive work behaviour and task performance.
Mediating role of organizational attractiveness on the relationship between green recruitment and job pursuit intention among students of Universiti Teknologi Malaysia

Abstract The purpose of this study was to investigate whether green recruitment practice attracts prospective candidates to join environmental responsible firms through organizational attractiveness. A total of 127 students from Universiti Teknologi Malaysia participated in the survey. SPSS version 23 was used to test the mediation model with the help of regression analysis. Results showed that green recruitment relates positively to job pursuit intention and organizational attractiveness partially mediates the relationship and students studying in universiti teknologi Malaysia have higher job pursuit intention towards environment responsible firms. Findings further highlight that green recruitment is a source of attracting potential candidates to pursue career in the green organizations and will allow practitioners to merge green human resource management with their traditional human resource policies to recruit quality candidates. Finally, by empirically providing positive outcomes this study adds to the body of literature in the field of green human resource management which is still at emerging stages.
Weed population, weed biomass and grain yield of wheat as influenced by herbicides application

A field experiment was conducted during Rabi seasons of 2015–16 and 2016–17 at Banka (Bihar) to evaluate the weed population, weed biomass and grain yield as influenced by herbicide application in wheat (Triticum aestivum L.). Seven weed species, viz. Phalaris minor, Cynodon dactylon, Chenopodium album, Oxalis purpurea, Anagallis arvensis, Medicago denticulata and Rumex dentatus infested the wheat field. Post-emergence application of sulfosulfuron 75% WG (25 g/ha) + metsulfuron-methyl 20% WP (2 g/ha) at 30 days after sowing (DAS) was very effective against broad-leaf weeds and annual grasses, and recorded significantly lower density and biomass of these weeds at 60 DAS as compared to isoproturon 75% WP 1.0 kg/ha, sulfosulfuron 75% WG 50 g/ha, metsulfuron-methyl 20% WP 4 g/ha and weedy check. Ear length, effective tillers/m2, grains/spike, grain and straw yields were also significantly higher in sulfosulfuron (25 g/ha) + metsulfuron-methyl (2 g/ha) as compared to other herbicide treatments.
Attitude and Practice of Aesthetic Surgery among Plastic Surgeons in Nigeria

BACKGROUND: Aesthetic surgery in developed countries is growing at an exponential rate. There is an increasing demand for cosmetic procedures in Nigeria but still, the practice is at a slow pace. Significant clients from Nigeria seek for these procedures outside Nigeria. OBJECTIVE: This study aimed at determining the attitude and practice of aesthetic surgery among plastic surgeons in Nigeria METHOD: We conducted a cross-sectional study among the attendees of the annual conference of the National Association of Plastic Reconstructive and Aesthetic Surgeons held at Calabar, Nigeria, using a questionnaire on consented participants. RESULTS: A total of 73 out of 84 Plastic surgeons participated in the study with a response rate of 86.9%. The mean age of the respondents was 45.4±7.2 years. Only 14 (19.2%) had undergone extra training in cosmetic surgery. Most respondents 53.4% prefer Nigerian over foreign hospitals for cosmetic surgery for various reasons. Poor awareness (42.5%) and religious beliefs (42.5%) contributed most to the poor acceptability of cosmetic surgery in Nigeria. The vast majority (97%) of Nigerian plastic surgeons want the public to be engaged in awareness sensitization on cosmetic surgery and their preferred mode of sensitization was through internet / social media (80.8%), television (74%), and radio (65.8%). Scar revision (78.1%) abdominoplasty (69.9%) and breast reduction (67.1) were the common cosmetic procedures performed by Nigerian plastic surgeons. CONCLUSION: The attitude of Plastic surgeons in Nigeria to cosmetic surgery is influenced by the low acceptance of cosmetic surgery procedures by Nigerians. Attitudinal change programs, especially through social and other mass media, are desired to increase awareness and acceptance of cosmetic surgery in Nigeria.
Beyond Dyads and Triads: A Comparison of Tetrads in Twenty Social Networks

Social psychologists focus on the microlevel features that define interaction, often attending to dyads and triads. We argue that there also is utility in studying how configurations of four actors, or tetrads, pattern our social world. The current project considers the prevalence of directed tetrads across twenty social networks representing five relationship types (friendship, legislative co-sponsorship, Twitter, advice seeking, and email). By comparing these observed networks to randomly generated conditional networks, we identify tetrads that occur more frequently than expected, or network motifs. In all twenty networks, we find evidence for six tetrad motifs that collectively highlight tendencies toward hierarchy, clustering, and bridging in social interaction. Variations across network genres also emerge, suggesting that unique tetrad structural signatures could define different types of interaction.
