Prevalence and associated risk factors of depression among housewives in rural Saharanpur, Uttar Pradesh, India

Introduction: Depression is the most common mental disorder. Women and the elderly have shown greater vulnerability to depression. Additional responsibilities due to modernization in rural areas have to lead to increased stress and tension among housewives. Limited data is available on depression among housewives in rural India especially Uttar Pradesh. So, the present study was planned to assess the prevalence of depression and its associated risk factors among housewives aged 18-59 years in the rural area of district Saharanpur, Uttar Pradesh. Objective: To assess the prevalence and risk factors of depression among housewives in the rural area. Methods: The study was done in five villages of Saharanpur, Uttar Pradesh from November 2018 to October 2019. A total of 500 housewives were selected by systematic random sampling. Interviews were conducted by the house to house visits. Depression was evaluated using the self-reported instrument Patient Health Questionnaire-9 (PHQ-9). The analysis was done using MS Excel software and SPSS software version 22. Results: The prevalence of depression was found to be 18%. There was an increasing trend in the prevalence of depression in the middle age group. The increasing level of education, marriage, better socio-economy, economic independence and absence of co-morbid conditions had a lower prevalence of depression. None of the depressed subjects had taken professional help. Conclusion: Housewives should be educated about warning signs and symptoms of depression and motivated to seek professional help.
Nation-wide estimation of groundwater redox conditions and nitrate concentrations through machine learning

The protection of water resources and development of mitigation strategies require large-scale information on water pollution such as nitrate. Machine learning techniques like random forest (RF) have proven their worth for estimating groundwater quality based on spatial environmental predictors. We investigate the potential of RF and quantile random forest (QRF) to estimate redox conditions and nitrate concentration in groundwater (1 km × 1 km resolution) using the European Water Framework Directive groundwater monitoring network as well as spatial environmental information available throughout Germany. The RF model for nitrate achieves a good predictive performance with an R2 of 0.52. Dominant predictors are the redox conditions in the groundwater body, hydrogeological units and the percentage of arable land. An uncertainty assessment using QRF shows rather large uncertainties with a mean prediction interval (MPI) of 53.0 mg l−1. This study represents the first nation-wide data-driven assessment of the spatial distribution of groundwater nitrate concentrations for Germany.

The Relationship between Capital Structure and Firm Value: Cases of Listed Companies in the Food and Beverages Industry in Vietnam

Food and beverages (FB the authors utilize financial data of 22 representatives in the period between 2014 and 2018 and the multi-regression models developed by Aggarwal & Padhan (2017). In the model, market capitalization and leverage are selected to represent for the capital structure and firm value, while other variables are considered as control variables which include firm quality, size, intangibles, profits, growth, liquidity and macroeconomic factors. The findings of the paper prove that the capital structure has positive relationship with the firm value. In addition, an increase in firm quality, tangibility, firm growth and GDP growth rate can improve the firm value. Besides, an increase leverage, or pursuing high profitability and liquidity associated with the existence of inflation would weaken firm value of F&B companies. The authors, therefore, recommend that fund managers and board of management should improve the strategic planning towards sustainable sources of funding and management cost of funding more efficiently.
Melanin biomaterial effectively eliminates bacteria from water and synergistically induces melanoma-cell death during X-ray irradiation

ABSTRACT In this study, we revealed that melanin biomaterial extracted from squid ink-sacs could effectively remove both gram-positive and gram-negative bacteria from water. A solid/liquid ratio of 25 mg/mL, melanin was able to remove 82% and 63% of E. coli and V. vulcificus, respectively; and, at any tested solid/liquid ratios of 5, 15, or 25 mg/mL, melanin could eliminate almost all B.cereus and S.aureus. FTIR analysis showed differences in chemical properties on surfaces of melanin in cases of with and without bacterial adsorptions. Besides, melanin nanoparticle (200 nm in size) at a concentration of 2 mg/mL had an antibacterial activity with antibacterial diameters of 17, 15, 12 and 14 for E.coli, V. vulfinicus, S. aureus and B.cereus, respectively. More interestingly, melanin nanoparticles could enhance killing ability of X-ray on SKMEL28 cell about 20%. Conlusively, we suggested that melanin biomaterial could be applied in different fields in biology depending on its existing forms.
Pattern of estrus response and conception rate following G6G and Ovsynch treatments in post-partum repeat breeding crossbred cows

This study was designed to evaluate the efficacy of G6G treatment on pattern of estrus response and conception rate over Ovsynch treatment initiated on random days of estrous cycle in post-partum repeat breeding crossbred cows. Sixteen (n=16) cows were equally divided into two groups viz., Group 1, which received Ovsynch treatment and Group 2, which received G6G treatment. The onset of estrus in Group 1 and 2 was 48.21±1.91 and 50.12±1.84 hrs respectively. The duration of estrus in Group 1 and 2 was recorded as 19.12±1.07 and 21.47±1.18 hrs respectively. In the present study, the conception rate was 12.50 and 50.00 percent in Group 1 and 2 following Ovsynch and G6G treatments respectively. It could be concluded that the use of G6G treatment was capable of responding better in terms of estrus response and conception rate in post-partum repeat breeding crossbred cows.
Risk-adjusted efficiency and bank size in a developing economy: an analysis of Vietnamese banks

PurposeThere is ample empirical evidence to show that larger banks are more efficient than smaller banks in developed countries. However, there is very little empirical evidence to show that in small developing economies, such as Vietnam, bank size is associated with increased risk, especially credit risk. This paper aim to provide empirical evidence to fill in this gap. This paper employs a slack-based directional distance function using the intermediation approach in measuring the inefficiency of banks in Vietnam during the period 2006–2015. Non-performing loans are used as an undesirable output to capture credit risk. The results show that small banks are more efficient than large banks at the mean level and across the entire distributions of inefficiency of the two groups. Input waste, output shortage and risk surplus of big banks are nearly three times higher than those of small banks. The results are robust under constant and variable returns to scale for production technologies. The study’s empirical results contribute to the ongoing debate on the merits of enlarging bank size in a small transitional economy and suggest that policy makers should pay attention to the risk and inefficiency of large banks to enhance the performance of Vietnam's banking system as a whole.Design/methodology/approachThis paper uses the non-radial slack-based directional technology distance function developed by Färe and Grosskopf (2010) to estimate the efficiency of banks using the data envelopment analysis technique. Data for 44 commercial banks are used.FindingsThe empirical results of the paper contribute to the ongoing debate on the merits of enlarging bank size in a small transitional economy and suggest that policy makers should pay attention to the risk and inefficiency of large banks to improve the performance of Vietnam's banking system as a whole.Originality/valueThis paper extends the extant literature by examining whether efficiency is associated with size in a typical transitional developing economy. The classic Cournot model, the structure-conduct-performance and the efficiency structure hypotheses state that larger banks are more efficient than smaller banks (Bikker and Bos, 2008). Empirical studies of Berger (2003), Mester (2005), Wheelock and Wilson (2012) lend support to the statement in developed countries. However, not much empirical literature focuses on small developing economies such as Vietnam to show that bank size is associated with increased risk, especially credit risk. The study’s empirical results show that size enlargement is not positively associated with risk-adjusted efficiency. Input waste, output shortage and risk surplus of big banks are nearly three times higher than those of small banks. The results are robust under constant and variable returns to scale for production technologies.

Governance Strategies to Drive Complementary Innovation in IoT Platforms: A Multiple Case Study

The widespread uptake of the Internet of Things spurred both software and hardware firms to compete for platform leadership. Information systems research has acknowledged that a platform’s success depends on the innovational output of its ecosystem of firms. However, the question whether platform owners should coordinate these firms through cooperative or competitive strategies to create complementary applications remains unaddressed. To address this gap, an exploratory, multiple case study of four German companies with IoT platforms was conducted. Five of the six governance strategies derived from the literature were confirmed: opening, alliancing, coring, entering, and pricing. In these strategies, 19 distinct governance mechanisms and their positive or negative effects were identified. The findings contribute to research on business-to-business platforms by demonstrating that cooperation between platform owners and complementors represents the dominant meta-level strategy in IoT platforms.
Digital Commons@Georgia Southern Digital Commons@Georgia Southern Effects of a Dual-Task Paradigm and Gait Velocity on Dynamic Effects of a Dual-Task Paradigm and Gait Velocity on Dynamic Gait Stability during Stair Descent Gait Stability during Stair Descent

Featured Application: The authors concluded that the inﬂuence of gait velocity should be considered when assessing the e (cid:11) ects of dual-tasks. Understanding the e (cid:11) ects of the interaction between the dual-task paradigm and gait velocity on dynamic gait stability may provide new insights into a dynamic postural control mechanism. Abstract: Falls during stair negotiation have become one of the leading causes of accidental death. The e (cid:11) ects of a concurrent cognitive or manual dual-task paradigm on dynamic gait stability remain uncertain. How much dynamic gait stability is inﬂuenced by gait velocity is also not clear. A total of 16 healthy young females descended a staircase under three di (cid:11) erent walking conditions: descend stairs only (single task), descend stairs while performing subtraction (cognitive dual-task), and descend stairs while carrying a glass of water (manual dual-task). An eight-camera Vicon motion analysis system and a Kistler force plate embedded into the third step of the staircase were used synchronously to collect kinematic and kinetic data. Gait velocity decreased and dynamic gait stability increased with both cognitive and manual dual-task conditions. The center of mass–center of pressure inclination angle increased with gait velocity but decreased with the manual dual-task condition compared to the single-task condition. Changes in gait velocity caused by the dual-task paradigm can partially explain the e (cid:11) ects of dual-task dynamic gait stability. The inﬂuence of gait velocity should be considered in the assessment of dual-task e (cid:11) ects.
Analysis of Competencies Models in Culinary Arts Higher Education

ABSTRACT Competency models act as a competency management platform and consist of mapping knowledge, skills, and attitudes. Purpose: To analyze, qualitatively, the competencies assessment instruments in Culinary Arts higher education present in literature. Methods: The study consists of a systematic literature review from the EBSCO platform, identifying the competency models used in the culinary arts. The models were analyzed concerning their foundation, application, population, data treatment, and the main results obtained. Results: Two seminal models were identified for the study of competences: Tas and Sandwith’s competency dimension models. These models have been applied in five studies in four countries. Gersh identified methodological progress regarding the two models, realizing that both were complimentary to each other, so he presented a fusion between the two seminal models. The main findings in the studies are that the techniques, leadership, and interpersonal relationship are the most relevant competencies in the culinary arts.
Spatial Characteristics of Transit-Integrated Ridesourcing Trips and Their Competitiveness with Transit and Walking Alternatives

Municipal transit agencies are exploring integrations with ridesourcing vehicles to extend the reach of their fixed-route transit networks. Ridesourcing integrations have been piloted in some regions, but these pilots tend not to be externally evaluated because of an inability to access the trip data. The primary objective of this research was to determine the types of trips passengers are taking through a transit-integrated ridesourcing pilot, and their competitiveness with transit and walking alternatives. The analysis focused on the 903 Flex pilot operated by the Region of Waterloo, Ontario, Canada. A set of 585 completed ridesourcing trips (rides) were studied and compared with the alternative transit and walking trips. Each ride was assigned a type, based on its proximity to transit and walking alternatives, for calculation and comparison of trip attributes. Terminology for types of rides is introduced and the categorization process applied to the ridesourcing pilot. Trip categories include: feeders, transit replacements, inconvenient trips, and remote trips. Results suggest that most trips in the study operated on an indirect feeder-like system (65%), which brought passengers between virtual ridesourcing stops and a transit stop, but not the transit stop closest to them. The alternative fixed-route transit trips mainly operated on 30-min headways, and alternative walking times were often long. The trips were found to mostly support or maintain transit usage, but the transit agency should be cautious of cases in which rides occur alongside transit (18%), instead of bringing people to it.
Discrete two dimensional Fourier transform in polar coordinates part II: numerical computation and approximation of the continuous transform

The theory of the continuous two-dimensional (2D) Fourier Transform in polar coordinates has been recently developed but no discrete counterpart exists to date. In the first part of this two-paper series, we proposed and evaluated the theory of the 2D Discrete Fourier Transform (DFT) in polar coordinates. The theory of the actual manipulated quantities was shown, including the standard set of shift, modulation, multiplication, and convolution rules. In this second part of the series, we address the computational aspects of the 2D DFT in polar coordinates. Specifically, we demonstrate how the decomposition of the 2D DFT as a DFT, Discrete Hankel Transform and inverse DFT sequence can be exploited for coding. We also demonstrate how the proposed 2D DFT can be used to approximate the continuous forward and inverse Fourier transform in polar coordinates in the same manner that the 1D DFT can be used to approximate its continuous counterpart.
A Contemporary Portrait of Black Women Student Affairs Administrators in the United States

Although Black women are the most represented minoritized group among U.S. higher education administrators, they continue to lag behind White women and men in terms of leadership in the student affairs profession, which may be exacerbated by their relative underrepresentation in graduate programs in education. Further, beyond generalized narratives about the aggregated experiences of Black women in higher education, little is actually known about the status and ambitions of contemporary Black women in student affairs. A secondary analysis of archival data extrapolated from a program evaluation survey provided preliminary insight into the educational and professional characteristics and aspirations of 401 Black women student affairs administrators who participated in the African American Women’s Summit. Findings revealed that the majority of participants had earned master’s degrees, were employed as assistant deans/directors, and were earning between $30,000–$49,999 annually. The most represented student affairs functional areas among participants were Housing and Residential Life Programs, followed by Multicultural Student Programs and Services. Most participants were employed at large, public, 4-year, predominantly White institutions. Further, despite hesitations about enrolling in doctoral programs and persisting in the profession, many participants still aspired to terminal degree completion and senior-level leadership. The data were interpreted in relation to existing research about the career pathways of chief student affairs officers and suggest that more specific strategies are needed to facilitate the promotion of Black women into student affairs leadership positions. While the findings of this study focused on a specific group of Black women student affairs administrators and thus should be applied cautiously, the portrait offered contributes to the scant body of literature about Black women employed in student affairs and suggests interim strategies that may be used to ameliorate their underrepresentation in the field.
Adsorption and migration growth of the Ce, O, and F adatoms on the CeO2 (111) surface: A density functional theory study

In order to investigate the microscopic behavior of the crystal surface growth of the fluorinated cerium dioxide polishing powder, the adsorption and migration of the Ce, O, and F atoms on the CeO2 (111) surface were studied by using density functional theory with Hubbard correction +U. The adsorption energies of three single atoms at five high‐symmetry sites and the migration activation energies along the migration pathway on the CeO2 (111) surface were calculated. Results show that the most stable adsorption sites of the Ce, O, and F atoms were the Oh, Cebri, and Cet sites, respectively. The Ce atom migrated from the Oh to the Ot site. The O atom migrated from the Cebri to the Obri site. The F atom migrated from the Cet to the Oh site. The migration activation energies of the Ce, O, and F atoms along the migration pathways were 1.526, 0.597, and 0.263 eV, respectively. The F adatom does not change the spatial configuration of the Ce and the O atoms. When the O vacancy occurs on the CeO2 (111) surface, the F adatom can make up for the O vacancy defect.
Demonstrating Short-Term Impacts of Grazing and Cover Crops on Soil Health and Economic Benefits in an Integrated Crop-Livestock System in South Dakota

Integrated crop-livestock system (ICLS) is an alternative that can help in intensifying food production while benefiting the environment. However, the assessments of the impacts of ICLS on the soil and economic benefits relative to specific environments in South Dakota are still lacking. This study was to assess the effects of ICLS on soil health and economic benefits under a corn (Zea mays L.)-soybean (Glycine max L.)-rye (Secale cereale L.) rotation in South Dakota. Cover crops blends were planted after the rye crop, and grazing treatments (with and without) were applied after the cover crops establishment in 2015-2016. Data from this study indicate that most soil properties are not negatively impacted by grazing. However, the grazing increased soil bulk density (BD) and decreased soil organic carbon (SOC) and soil water retention (SWR) compared with the ungrazing. The effect of grazing on corn yield was not significant. The cover crops did not impact the pH, electrical conductivity (EC), total nitrogen (TN), β-glucosidase, acid hydrolysis carbon fraction, microbial biomass carbon, and SWR, but impacted the SOC, hot/cold water carbon fraction, BD, infiltration rate (qs) in some phases and depths. The effects of different cover crop blends on corn yield were not as strong. The economic analysis showed that implementing ICLS increased the profit of the farm by $17.23 ac−1 in the first year and $43.61 ac−1 in the second year. These findings indicate that ICLS practices with proper management benefit soil health and producer income.
