Optimal Task Allocation and Coding Design for Secure Edge Computing With Heterogeneous Edge Devices

In recent years, edge computing has attracted significant attention because it can effectively support many delay-sensitive applications. Despite such a salient feature, edge computing also faces many challenges, especially for efficiency and security, because edge devices are usually heterogeneous and may be untrustworthy. To address these challenges, we propose a unified framework to provide efficiency and confidentiality by coded distributed computing. Within the proposed framework, we use matrix multiplication, a fundamental building block of many distributed machine learning algorithms, as the representative computation task. To minimize resource consumption while achieving information-theoretic security, we investigate two highly-coupled problems, (1) task allocation that assigns data blocks in a computing task to edge devices and (2) linear code design that generates data blocks by encoding the original data with random information. Specifically, we first theoretically analyze the necessary conditions for the optimal solution. Based on the theoretical analysis, we develop an efficient task allocation algorithm to obtain a set of selected edge devices and the number of coded vectors allocated to them. Using the task allocation results, we then design secure coded computing schemes, for two cases, (1) with redundant computation and (2) without redundant computation, all of which satisfy the availability and security conditions. Moreover, we also theoretically analyze the optimization of the proposed scheme. Finally, we conduct extensive simulation experiments to demonstrate the effectiveness of the proposed schemes.
Quaring Sorority Life: Identity Negotiation of Queer Women of Color in Culturally Based Sororities

Abstract:Using quare theory as a theoretical framework and critical narrative inquiry as a methodology, researchers centered the stories of 20 queer Women of Color affiliated with culturally based sororities. Participants spoke about how they perceived gendered and heterosexist norms in their sororities and how they negotiated their identities in these environments. Findings reveal that queer Women of Color made crucial decisions regarding their identity negotiation while in the process of joining their organizations. Moreover, some participants articulated how, once affiliated, they strategically minimized attention to their sexuality and gender, while others asserted these identities to disrupt hegemonic norms.
Low-income mothers’ participation in the Understanding DadsTM intervention and changes in self-reported coparenting

ABSTRACT This study presents findings of a mother-only coparenting intervention conducted in conjunction with fathers’ participation in a fatherhood program. Specifically, this study sets out to determine whether there is an association between mothers’ participation (N = 127) in the group-based intervention, Understanding Dads™, and changes in mothers’ reports of the coparenting relationship and mothers’ coparenting attitudes. The findings of this one group pretest/posttest/follow-up study showed that mothers reported fewer disagreements and less undermining of fathers following participation in the intervention. Mothers also indicated greater confidence in their ability to coparent cooperatively with the father after participation. Implications for fatherhood programs are discussed.
The COVID-19 Vaccination Debate: CoV-2 in Celiac Disease: A Pathogen or just along for the Ride?

SARS-CoV-2, the virus that causes COVID-19, impacts human health all over the world with high morbidity and mortality. Many chronic diseases predispose the patients to be infected, including autoimmune diseases. Despite theoretical and rare exceptions, celiac disease is not a high-risk condition for COVID-19 infection. The present review expends on those potential circumstances that put the CD patients at risk for COVID-19.
The impact of COVID-19 on changes in community mobility and variation in transport modes

ABSTRACT Using Google mobility data and Apple maps data we track changes in community mobility and transport modes during the COVID-19 Alert levels. Results show that Alert Level 4 – lockdown had a significant impact on the reduction in mobility and variation in transport mode. Mobility and transport mode progressively returned to pre-Alert Level 4 patterns with the exception of public transport. Regional heterogeneity in the variation of public transport use was evident in the data. Containment measures also had a significant negative effect on retail and recreation. Otago had a significantly delayed recovery in retail and recreation relative to other regions.
Influence of Salary Administration and Conflicts Management on Organizational Performance

Frequent organizational conflict resulting from continuous, agitation by workers for improved working conditions such as increment in salaries, gratuity, pension benefits, allowances and other interests have led to a down toll which eventually affects organizations performance and has taken a comparative nosedive sequence which is a confirmation that organizational performance is enhanced through effective conflict management. The study investigated the influence of salary administration and conflict management on organizational performance among university college hospital staff. The theories of Goal Setting, Capital and Abraham Maslow's provided the framework for this research. A cross sectional survey with an ex-post facto design was utilized in gathering data from University College Hospital (UCH) through purposive sampling technique. A total of two hundred two four (224) employees of UCH were sampled and data gathered was analyzed using t-test for independent sample and multiple regression analysis. Findings revealed that conflict management had a significant influence on organizational performance among employees in UCH [t (222) = 2.98; P<. 01]. Also, salary administration had a significant influence on organizational performance among employees in UCH [t (222) = 4.32; P<. 01]. In addition, when combined, conflict management and salary administration jointly influence organizational performance [R = . 32; R2 = . 10; F (2, 221) = 11.92; P<. 01]. The study concluded that conflict management and salary administration were significant determinants of organizational performance. It was therefore recommended that UCH management should endeavour to encourage utilization of integrating employees to work together and learn to tolerate each other.
Domestic Violence Policy: A World of Change

The second wave of the feminist movement brought unprecedented changes in awareness of criminal legal system (CLS) responses to domestic violence (DV). The seemingly feminist “success” in the harsher CLS responses, however, resulted in the disparate criminalization of BIPOC (Black, Indigenous, and People of Color) and poor individuals, among both DV defendants and victims. Therefore, feminist support for anti-carceral/abolitionist feminism, recognizing the cooptation of feminist ideals within a neoliberal CLS system, has grown. Colonial policing, however, has only tangentially been applied to DV (and other gender-based abuse offenses’) CLS responses. This article advocates for significant changes to policing DV.
Microstructural and Mechanical Characterization of W-CuCrZr Joints Brazed with Cu-Ti Filler Alloy

The determination of the mechanical properties of a brazed joint is an important factor to reach the metallurgical level of a joint development. This paper evaluates the mechanical properties, and its correlation with the joint microstructure, of a W-CuCrZr joint brazed in a high vacuum furnace using 80Cu-20Ti flexible filler material in tape form. This joint is meant to be implemented in the divertor application in future fusion power plants. Main experimental parameters were a brazing temperature of 960 °C and a dwell time of 10 min. The microstructure of the joint was constituted by Cu solid solution and Cu4Ti phases. This last phase was distributed in the W-braze interface. Mechanical properties were evaluated by means of Vickers microhardness and mechanical tests by applying pure shear loads. The microhardness profile of the brazed joint indicated that W remained with the as-received hardness but CuCrZr base material was softened after the brazing procedure. Shear strength of 96 ± 15 MPa was obtained for the brazed joint and fracture propagated at the W-braze interface.
Alone in the Gym: A Review of Literature Related to Physical Education Teachers and Isolation

Feelings of isolation have long been found to be experienced by many teachers, particularly by those within some specialist disciplines, including physical education (PE). The potential effects of teacher isolation are undesirable and plentiful. They include a lessening of interest in one’s work, burnout, and/or an absence of community connection. Given the uniqueness of their discipline, PE teachers may especially be impacted by the following: Their discipline is “low status” and marginalized, they are frequently both physically and psychologically isolated from their peers, and they often are one of very few PE specialists in a school. Given these sorts of unique challenges for PE teachers, the authors undertook a scoping review of literature in order to gather and provide a comprehensive and up-to-date account of peer-reviewed literature related to PE teachers and isolation, as well as offer implications for PE research and practice.
Prevalence of Y Chromosome Microdeletion Among Mongolian Infertile Men With Azoospermia and Severe Oligozoospermia

Backgound: Y chromosome microdeletions are the second most common genetic causes in male infertility. The aim of the present study was to reveal the patterns of Y chromosome microdeletions among Mongolian infertile men. Method: A descriptive study was performed to 75 infertile men during February 2017 to December 2018. Y chromosome microdeletions were identified by PCR. Semen parameters, hormonal levels, testis biopsy were determined. All collected data were evaluated with Statistical Package for Social Sciences (SPSS, version 22.0). Results: Among 75 infertile men, 2 cases of Y chromosome microdeletions were determined (2.66%). The first case had AZFa complete deletion and the other one had AZFc partial deletion. The azoospermia patient with AZFa complete deletion had Sertoli cell only syndrome in the testis biopsy, FSH 58.0 mIU/ml and LH 12.0 mIU/ml. The azoospermia patient with AZFc partial deletion showed FSH 23.85 mIU/ml and LH 13.01 mIU/ml. Serum FSH level was significantly higher in the Y chromosome microdeletion patients (p value 0.016). Conclusion: This study determined Y chromosome microdeletion among Mongolian infertile men to be at 2.66%. Our results showed FSH level is the best predictor of a successful TESE. However, best cut off value for FSH was 9.69 mIU/ml with a sensitivity and specificity 85.6% and 83.3% respectively. There is a possibility that sperm retrieval will be difficult from the TESE since the testicular tissue is severely damaged. The findings can be applied to IVF and Assisted Reproductive Techonology, and our results will help clinicians improve treatment management for Mongolian infertile couples.
Prescribers’ Adherence to Treatment Guidelines for Uncomplicated Malaria in Primary Health Centres in Bayelsa State, Nigeria

Background: Malaria, though preventable and treatable, remains a disease with unacceptably high mortality in Nigeria. Effective and prompt treatment of uncomplicated cases reduces progression to severe disease, development of drug resistance, and cuts the costs of the disease.Objective: To assess adherence by prescribers to recommended treatment (based on National Treatment Guideline) for uncomplicated malaria in primary health centres (PHCs) in the eight Local Government Areas (LGAs) of Bayelsa State, Nigeria.Methods: A retrospective review of case notes and prescription sheets for suspected malaria cases treated at 28 PHCs within a year of data collection was done. Relevant data about the prescribers, the patients, and the antimalarial drugs prescribed were collected and analyzed as appropriate.Results: A total of 2,303 case notes of patients attending PHCs were examined over the study period. A high proportion of malaria (1422, 61.7%) was observed among the 2,303 cases. The median age (years) of adults was 28.0 (IQR = 14), and for children of 0-5, 2.0 (IQR = 2.17). Majority of those treated were females (792, 55.7%) and children (967, 68.0%). Artemisinin-based combination therapies (ACTs) were the most prescribed antimalarials (961, 67.6%), followed by artemisinin monotherapies in 23.8% of cases. Proportion of treated cases of malaria that could be considered rational across the LGAs was 67.6%. Conclusion: Adherence of prescribers to National Treatment Guidelines of uncomplicated malaria in PHCs in Bayelsa State was below the required standard, with continued usage of obsolete agents, such as artemisinin monotherapies. Training on case management for prescribers at this level of care is urgently needed. Keywords: Antimalarial drugs, Malaria, Primary Health Centres, Community Health Workers, Bayelsa State.
Land-based climate change mitigation potentials within the agenda for sustainable development

Even though enormous expectations for greenhouse gas mitigation in the land use sector exist at the same time worries about potential implications for sustainable development have been raised as many Sustainable Development Goals (SDGs) are closely tied to developments in the sector. Here we assess the implications of achieving selected key SDG indicators for Zero Hunger, Clean Water and Sanitation, Responsible Consumption and Production, and Life on Land on the land-based climate change mitigation potential. We find that protecting highly biodiverse ecosystems has profound impacts on biomass potentials (−30% at >12 US dollar per gigajoule) while other SDGs mainly affect greenhouse gas abatement potentials. Achieving SDGs delivers synergies with greenhouse gas abatement and may even in the absence of additional mitigation policies allow to realize up to 25% of the expected greenhouse gas abatement from land use required to stay on track with the 1.5 °C target until 2050. Future land use mitigation policies should consider and take advantage of these synergies across SDGs.
The structure and composition of microspheres from the Kilauea Volcano, Hawaii

Microspheres from the plume of the Kilauea volcano, Hawaii, display previously unrecognized structural and compositional features indicating that the spheres are concentrically differentiated and at least partially crystalline. The surfaces of some spheres display evenly spaced hexagonal, sub-micrometer grains whose compositions suggest that they may be spinels. Distinctive prismatic and dendritic structures on the surfaces of the microspheres are remarkably consistent through the population and indicate that the spheres have crystalline outer shells. Indications of chemical etching are present, probably from exposure to HF in the volcanic plume. The structures and compositions of the microspheres suggest that they differentiated and then solidified during rapid cooling, as they passed through the gradients of temperature, chemical composition, and redox conditions established in the plume as air diluted the gaseous species evolved from magma.
Phenolic compounds in an ethanol-water extract of oak wood and in a brandy

An ethanol-water extract of oak wood and a cask-aged brandy were compared in order to assess the contribution of oak wood and the changes which may occur during storage of spirits in oak barrels. Phenolic compounds were separated into 10 fractions by preparative liquid chromatography in these two models. Individual analysis of the fractions in methoxyl groups and total phenolic compounds revealed different distribution of contents in the ethanol-water extract and in the brandy. In addition, overall alkoxyl content was dominant in the cask-adged brandly compared to the macerated oak wood preparation
Apparent digestibility coefficients of local palm kernel cakes, rice bran, maize bran and sago flour in the GIFT strain of Nile tilapia (Oreochromis niloticus)

ABSTRACT An experiment was conducted to estimate the apparent digestibility coefficients (ADC) of macronutrients and energy of local palm kernel cakes, rice bran, maize bran and sago flour in Nile tilapia, Oreochromis niloticus (average initial body weight of 30.49 ± 0.38 g). A reference (basal) diet was formulated to contain 33% crude protein, 7% crude fat and 390 Kcal/100 g diet, all on a dry matter basis. The acid-insoluble ash was used in all the diets as the digestibility marker. The experiment lasted 37 days, including a growth phase of 28 days followed by a feces collection phase of 9 days. The results showed that the ADCs of dry matter, crude protein, crude lipid, ash, crude fiber, total carbohydrate and gross energy were 79.74%, 83.53%, 78.79%, 83.84%, 75.53%, 78.20% and 79.25% for the conventional palm kernel cake, 46.36%, 34.59%, 47.89%, 34.94%, 60.35%, 51.69% and 47.96% for refined palm kernel cake, 58.67%, 51.00%, 65.10%, 60.39%, 63.59%, 59.44% and 60.50% for rice bran, 79.24%, 94.03%, 80.34%, 99.69%, 83.83%, 76.85% and 78.61% for maize bran, and 33.74%, negative value, negative value, negative value, 8.49%, 47.65% and 35.96% for sago flour in tilapia, respectively. The present study generated original information on the digestibility of nutrients contained in these local foodstuffs, which represents a baseline, original information that could be used to formulate least-cost local feeds. However, to account for the changes in the nutrient content of these local associated with seasonality, plant variety and improvement in ingredient processing on the quality of the ingredients available on local markets, it would be interesting to collect additional samples, several times a year and run similar digestibility experiments on a regular basis, in order to have a comprehensive database that could be used by local feed miller to manufacture feed for small fish farm holders.

Physicians' Biological Drug Preference in Patients With Rheumatoid Arthritis and Spondyloarthritis With a History of Malignancy

Objective Because of concerns about malignancy risks, using biological disease-modifying antirheumatic drugs (bDMARDs) in patients with a history of malignancy remains a challenging issue in rheumatology practice. This study aimed to investigate bDMARD preferences of physicians when treating of rheumatoid arthritis (RA) and spondyloarthritis (SpA) patients with a history of malignancy. Methods The data for this cross-sectional study were gathered from the TReasure database using a date range of December 2017 and January 2020. Biological disease-modifying antirheumatic drug preferences were analyzed for 40 RA patients and 25 SpA patients with a history of malignancy. Results The most frequently prescribed bDMARD was rituximab, which was given to 28 RA patients (70%). For 25 patients (62.5%), the time between the diagnosis of malignancy and starting on a bDMARD regimen was less than 60 months, with a median interval of 43.5 months. Among SpA patients, the preferred bDMARDs were secukinumab and etanercept, which were each administered to 7 patients (28%). For 13 SpA patients (52%), the time between the diagnosis of malignancy and starting on bDMARDs was less than 60 months, with a median interval of 97 months. Conclusions The observed bDMARD preferences may be related to the therapeutic effects of rituximab on lymphoproliferative malignancies, the protective effects of secukinumab on tumor progression, and the short half-life of etanercept. Biological disease-modifying antirheumatic drugs should be used in RA and SpA patients with malignancy in case of high inflammatory activity.
Performance of Retail Stores at Airports and Their Role in Boosting Traveler Satisfaction and Willingness to Repurchase

Despite its criticality for airport business, duty-free shopping at the retail stores of airports has received scant attention. To overcome this difference, this study explains the complex process via which travelers show their willingness to repurchase in the context of airport retail stores. A quantitative process comprising a field survey is conducted for data collection. The measurement quality is assessed and established through the evaluation of a measurement model. As a result of analyzing the structural equation model, it was found that the perceived performance, utilitarian value, hedonic value, and satisfaction evaluation of airport retail stores play a crucial role in determining traveler willingness to repurchase. The conceptual framework encompassing these concepts also adequately accounts for traveler willingness to repurchase. Moreover, our results from the invariance assessment reveal that the moderating impact of shopping engagement on the hypothesized relationship between utilitarian value and satisfaction evaluation is significant. Overall, the proposed direct associations among theoretical constructs within our framework are well supported. Furthermore, the efficacy of the proposed theoretical framework for a clear understanding of airport shoppers’ post-purchase behaviors is successfully identified.
Computational Fluid Dynamic Analysis of the Pharyngeal Airway after Bimaxillary Orthognathic Surgery in Patients with Mandibular Prognathism

This study aimed to analyze pharyngeal airflow characteristics and their relationship with the skeletal movement of the maxilla and mandible after bimaxillary orthognathic surgery in patients with skeletal class III (mandibular prognathism) malocclusion. Cone-beam computed tomography (CBCT) was conducted before surgery (T0), immediately after surgery (T1), and at least six months after surgery (T2). Digital imaging and communications in medicine files were transferred to InVivo (Anatomage) software to measure the skeletal changes after surgery. The changes in the maxillary and mandibular position, tongue position, and hyoid bone position were analyzed. Patient-specific models were reconstructed using 3D-Doctor software. The models after converting to the stereolithography (STL) file for Ansys integrated computer engineering and manufacturing code for computational fluid dynamics (ICEM CFD), commercial software were used for calculating the geometry, pressure drop and adjusted pressure coefficient value. The total volume of the upper airway including nasal cavity was reduced by 23% immediately after surgery and recovered to 92.2% of the initial volume six months after surgery. The airflow computation analysis showed a decrease in the pressure drop values immediately after surgery and six months after surgery. The adjusted pressure coefficients were slightly different but the change was statistically insignificant. The airflow characteristics computed using the computational fluid dynamics were correlated to the surgical changes. The surgical changes can affect the aerodynamics of the pharyngeal airway. In clinical practice, this knowledge is useful for developing a suitable orthognathic surgery treatment plan.
