Evaluation of machine learning approaches for prediction of pigeon pea yield based on weather parameters in India.

Pigeon pea is the second most important grain legume in India, primarily grown under rainfed conditions. Any changes in agro-climatic conditions will have a profound influence on the productivity of pigeon pea (Cajanus cajan) yield and, as a result, the total pulse production of the country. In this context, weather-based crop yield prediction will enable farmers, decision-makers, and administrators in dealing with hardships. The current study examines the application of the stepwise linear regression method, supervised machine learning algorithms (support vector machines (SVM) and random forest (RF)), shrinkage regression approaches (least absolute shrinkage and selection operator (LASSO) or elastic net (ENET)), and artificial neural network (ANN) model for pigeon pea yield prediction using long-term weather data. Among the approaches, ANN resulted in a higher coefficient of determination (R2 = 0.88-0.99), model efficiency (0.88-1.00) with subsequent lower normalised root mean square error (nRMSE) during calibration (1.13-12.55%), and validation (0.33-21.20%) over others. The temperature alone or its interaction with other weather parameters was identified as the most influencing variables in the study area. The Pearson correlation coefficients were also determined for the observed and predicted yield. Those values also showed ANN as the best model with correlation values ranging from 0.939 to 0.999 followed by RF (0.955-0.982) and LASSO (0.880-0.982). However, all the approaches adopted in the study were outperformed the statistical method, i.e. stepwise linear regression with lower error values and higher model efficiency. Thus, these approaches can be effectively used for precise yield prediction of pigeon pea over different districts of Karnataka in India.

Successful Aging in the Indian Socio-cultural Milieu.

There is a growing recognition of the importance of subjective definitions of successful aging from a clinical and policy perspective, and for their social and cultural relevance. However, the voices of older Indians remain largely underrepresented in the emerging body of qualitative literature on successful aging. Given this gap, and India's burgeoning older population, the present study set out to examine their subjective perception of successful aging. Using convenience sampling, data was collected from older men and women (N = 63, M Age = 71.21) living in the community, and in old age homes in Delhi NCR, through face-to-face interviews and focus group discussions. Reflexive thematic analysis resulted in four primary themes and eight sub-themes - Successful Aging as Personal Well-being, Tensions between Agency and Fatalism, comprising three sub-themes viz. the person as an active agent, co-existence of agency and fatalism, and negotiating with the invisible powers; Linked Lives comprising two sub-themes viz. the aging parent and the adult child, and spousal interrelationship; and The Social and Built Environment comprising three sub-themes, viz. complexity of social life: the health interface, social life in the neighborhood, and the good house. These findings provide a culture-specific view of successful aging in the Indian context, and reveals the multifaceted conceptualization of successful aging of older Indians - one that encompasses various biopsychosocial components.

Effect of dimensions on function: A 2-dimensional sonographic assessment to correlate facial muscle and smile type.

OBJECTIVE: The aim of this study was to measure the dimensions of the select facial muscles and correlate them with different types of smiles. METHODS: The study group included 30 South Asian adults (17 men and 13 women) aged between 24 and 30 years divided into 3 groups of 10 subjects each according to Rubin's classification of smile. The zygomaticus major, levator labii superioris, depressor anguli oris, and mentalis muscles were ultrasonographically evaluated. The length and thickness of the muscles were measured bilaterally. The data obtained were analyzed statistically. RESULTS: The maximum mean value thickness of the zygomaticus major was found in the canine smile group. The maximum mean value thickness of the depressor anguli oris and mentalis was seen in the full denture smile group. However, the thickness of the levator labii superioris muscle was similar between the different smile groups. There was no significant difference in the measurements of the length of the muscles between the right and the left sides. CONCLUSIONS: This study did not find any statistically significant correlation between the type of smiles described in Rubin's classification and the dimensions of the associated facial muscle.

Stress management training and gratitude journaling in the classroom: an initial investigation in Indian context.

Stress and allied difficulties are pervasive among school students in present times. This concern is further magnified in the Indian context with the large represention of young people in the population and limited resources to match. The present study aimed to evaluate the impact of a classroom based stress management training and gratitude journaling intervention (Flinchbaugh et al., 2012) among Indian adolescents. The intervention curriculum was adapted to suit the study context. A total of 238 students (57% males) from Grades 7-9 participated in this study. Participants were recruited from two schools, and their age ranged from 11 to 14 years. In each participating school, students were randomised at the classroom level into three intervention groups (Stress Management Training, Gratitude Journaling, combination of both), and one control group. Using a pre-test - post-test design, intervention impact on measures of well-being, life satisfaction, perceived stress, meaning, and engagement in the classroom was evaluated. Results suggested limited effectiveness of stress management training and gratitude journaling among participants in the present context. Plausible explanations for these findings are discussed. The study emphasizes the need for customised interventions to obtain optimal outcomes among diverse populations.

Religion and Well-Being: The Mediating Role of Positive Virtues.

Researchers have consistently advocated positive associations between religion and well-being. The present research takes a step forward and explores potential mechanisms behind the same. The mediating role of a surprisingly neglected mechanism, positive virtues, specifically gratitude, forgiveness and altruism, is studied through a quantitative study on a sample of 220 adult respondents residing in Delhi NCR. The participants adhered to one of the six major religions present in India. Mediational analysis revealed that gratitude mediated the relationship between religiosity, spirituality and well-being via two pathways of forgiveness and altruism. The implications for researchers and practitioners working in the field of mental health are discussed.

The Ashtanga Yoga Hindi Scale: An Assessment Tool Based on Eastern Philosophy of Yoga.

The study imports the concept of Ashtanga Yoga from the eastern philosophy of Yoga. There is a major disconnect between theory and data in Indian Psychology. Indian Psychology provides a rich theoretical base for understanding optimal human functioning. However, the theories have not been tested due to paucity of tools. A test developed on Ashtanga Yoga is reported. Data were collected in two phases from 550 participants. The data were analyzed using exploratory factor analysis. Seven factors were extracted as the theory indicates. Overall reliability of the scale was found to be excellent (α = 0.88), and the criterion-related validity was satisfactory as correlations were found to be 0.46 and 0.48 (p < 0.01) for Flourishing and SPANE-P, respectively, and -0.22 (p < 0.01) for SPANE-N.

Revalidation of the Sat-Chit-Ananda Scale.

Sat-Chit-Ananda is an indigenous construct that refers to absolute bliss and consciousness. The present study aimed to strengthen the psychometric properties of the newly developed Sat-Chit-Ananda scale (Singh et al. in Int J Vedic Found Manag 1(2):54-74, 2014). A total of 398 students aged 17-36 years (mean age = 21.33 years, SD = 2.2, 70% males) participated in this study. An exploratory as well as confirmatory factor analysis was computed for the 17-item scale. Its' concurrent validity was established by assessing its correlation with other well-being measures, namely Flourishing (Diener et al. in Soc Indic Res 97:143-156 2010) and Scale of Positive and Negative Experience (Diener et al. 2010). Satisfactory results were obtained from both exploratory and confirmatory factor analyses. Sat-Chit-Ananda and its factors were found to be significantly positively correlated with Flourishing and Positive Experiences and were negatively correlated with Negative Experiences. Thus, the validity of the Sat-Chit-Ananda (Singh et al. 2014) scale stands further substantiated-offering this scale as a promising new assessment tool.

Mental health and psychosocial functioning in adolescence: an investigation among Indian students from Delhi.

While developmental studies predominantly investigated adolescents' mental illness and psychosocial maladjustment, the present research focused on positive mental health of Indian adolescents within the Mental Health Continuum model. Aims were to estimate their prevalence of mental health and to examine its associations with mental distress and psychosocial functioning, taking into account age and gender. A group of 539 students (age 13-18; 43.2% girls) in the National Capital Territory of Delhi completed Mental Health Continuum Short Form, Depression Anxiety and Stress Scales-21, Strengths and Difficulties Questionnaire. Findings showed that 46.4% participants were flourishing, 51.2% were moderately mentally healthy, and only 2.4% were languishing. A higher number of girls and younger adolescents were flourishing compared to boys and older adolescents. Moreover, flourishing youths reported lower prevalence of depression and adjustment difficulties, and more prosocial behavior. Findings support the need to expand current knowledge on positive mental health for well-being promotion in adolescence.

A rare case of spontaneous inguinal faecal fistula as a complication of incarcerated Richter's hernia with brief review of literature.

BACKGROUND: Richter's hernia has an early misleading presentation with tendency to strangulation due to common lack of obstructive symptoms which may lead to delay in diagnosis and hence increased mortality. Rarely inguinal Richter's hernia may present with an uncommon complication of spontaneous fistula. The development of spontaneous faecal fistula secondary to incarcerated inguinal hernias is much rarer among the adult population as compared to the paediatric age group. Most of these fistula have been reported from developing countries like India and Nigeria and is usually the result of poverty, lack of knowledge, neglect, late presentation and lack of proper management. CASE PRESENTATION: A 62 years old male presented with chief complaints of multiple openings with faecal discharge in the right groin for last 20 days with no history of constipation, trauma, and urinary or other abdominal complaints. CT scan revealed a small gut loop communicating with anterior abdominal wall. Exploratory laparotomy revealed a loop of distal ileum adherent to the internal inguinal ring which was retrieved back into the abdominal cavity. There was perforation over the loop. Resection of the segment of ileum involved was done with ileo-ileal hand sewn anastomosis and the internal inguinal ring was closed from inside of the peritoneal cavity. The openings in the skin over the inguinal region were communicated with each other and laid open due to cellulitis of the area involved and pus discharge. CONCLUSION: Spontaneous faecal fistula in inguinal region following rupture of strangulated Richter's hernia especially in adults is very rare and can occur even in absence of obstructive symptoms. In presentation of any groin swelling, there is need for an early accurate diagnosis followed by prompt treatment. The delay in its diagnosis and management may result in this rare complication of spontaneous faecal fistula. This reflects the state of health care in the developing world and needs to be addressed by the concerned authorities.

Development and Validation of the Adaptive Schema Questionnaire.

Background: Schemas help with the organization and interpretation of information. Adaptive schemas indicate positive predisposing thinking patterns in an individual. This study aimed to develop a psychometrically robust tool to assess adaptive schema in a nonclinical sample. Method: This research comprises two independent studies. Study I was multiphased. In Phase I (n = 70), 36 open-ended items were generated following the Young schema therapy model and qualitatively analyzed. This facilitated the generation of 144 items in Phase II (n = 152) which were evaluated for content validity and subjected to rigorous item analysis. Exploratory factor analysis was performed in Phase III (n = 751). Confirmatory factor analysis was conducted in Study II (n = 244). Results: Exploratory factor analysis resulted in a six-factor solution comprising 25 items. These factors correspond to the six adaptive themes, namely, adequate, secured, self-reliant/autonomous, resistant, successful, and self-assured. The newly developed Adaptive Schema Questionnaire demonstrated adequate reliability (α = 0.86). Significant correlations between the obtained factors and Early Maladaptive Schemas, depression, big five personality factors, and positive and negative effects established the concurrent validity. Confirmatory factor analysis indicated acceptable goodness of fit for the obtained model. Conclusion: The developed Adaptive Schema Questionnaire is a reliable and valid instrument with promising utility in psychotherapy and research context.

Knowledge, Attitude, and Practice of Patients toward Dental Implants in Need of Prosthodontic Rehabilitation.

Background: Our goal in conducting this study was to see how well-informed patients are about dental implants as a method of prosthodontic rehabilitation. Materials and Methods: "In this cross-sectional study, 500 new dental students were asked questions using a pre-made, self-administered questionnaire. A pilot study was carried out to verify the reliability of the survey instrument. Analysis of the data was performed in SPSS 16 (SPSS). We used the P 0.05 thresholds for the Student's T-test and the ANOVA to determine statistical significance." Results: In all, there were 500 people involved: 320 men and 180 women. The media and dentists were the two most common places to learn about implants, and as patients received more information, they became more informed consumers. Many people put off getting therapy because of how expensive it is. Conclusion: Only a small percentage of individuals had implants, and more than half knew nothing about them. This finding also highlighted the need of educating patients more thoroughly on this therapy option. As a result, the public has to be educated about oral health and implants in order to adopt a more favorable perspective.

Microbiological biodiversity in poultry and paddy straw wastes in composting systems.

Immense quantity of waste is generated in association with poultry meat egg and crop production. The potential risks due to disposal of these wastes are magnified as a result of dense refinement of poultry production and the decreasing amount of land available for waste disposal. The study aims at studying the microbiological biodiversity of poultry waste and paddy straw based co-composting system. The predominant microflora of the poultry manure were bacteria, fungi, enteric bacteria and spore forming bacteria whose population was high at the initiation of composting but decreased significantly as the compost approached maturity. The initial load of inherent enteric groups of bacteria in poultry waste, that also includes some pathogenic ones, is considerably reduced and some new vital groups contributed to compost quality as the microbiological biodiversity sets in the system and becomes stable. Major fraction of nitrogen of poultry waste was subjected to ammonia volatilization and a fraction of it conserved by co-composting it in conjunction with wastes having low nitrogen contents. In the treatment T1 and T5, where poultry manure and paddy straws alone were composted, 60 and 30 percent of organic carbon, respectively, was lost over a period of six months. Whereas in treatments T2,T3 and T4, poultry manure and paddy straw were co-composted in the ratio of 3:1, 2:2 and 1:3, respectively, 51.4,45.0 and 37.0 percent of carbon, respectively, was lost during decomposition. The C: N ratio in all the treatments decreased significantly to 18.3 for T1, 24.7 for T2, 27.0 for T3, 34.9 for T4 and 38.5 for T5 at the end of composting period.

Personal wellbeing among adolescents and youth in India.

This study sought to explore the level of personal wellbeing and identified the determinants of happiness among Indian adolescents and youth. Data were collected from a sample of 495 participants (aged 11-23 years) residing in the National Capital Region of Delhi (Delhi-NCR), using the bilingual version (Hindi and English) of the Personal Wellbeing Index (PWI). Their PWI score was 80.06, indicating high happiness levels in the nonwestern normative PWI range. Domains of personal relationships, community connectedness, and safety represented high overall wellbeing with the highest mean scores. Multivariate analysis showed that the least happy group on life as a whole domain was students aged 19-23 years as compared with the 11-14 and 15-18 years age group. Furthermore, men had higher happiness levels on personal safety, while women had higher scores on life achievement. The qualitative analysis illustrated the socio-cultural basis of these wellbeing determinants as rooted in the hierarchical social structures and collectivistic cultural orientation.

An Exploratory Study on Subjective Perceptions of Happiness From India.

The present study aimed at understanding the subjective perception of happiness in a sample of Indian participants from diverse socio-economic backgrounds. Using convenience sampling, individual interviews were conducted with 60 participants aged between 19 to 73 years (M Age = 40 years). This study employed reflexive thematic analysis to analyse the written transcripts. Nine themes were generated which captured the essence of happiness for Indians-Feelings and Expressions of Happiness; Human Ties and Happiness which encompassed four sub-themes-family bond, the company one keeps, the pandemic and social disengagement, and the nation, society and happiness; Satisfaction with Material Needs and Resources; Lifestyle and Health; Work and Play; Accomplishment and Appreciation; Nature Connectedness; Religious and Spiritual beliefs; and Happiness as a Personal responsibility-Role of Positive Personality Traits. These findings revealed our respondent's multidimensional conceptualization of happiness, and adds to the growing body of happiness literature from the South Asian context.

Measurement Invariance of the Scale of Positive and Negative Experience Across 13 Countries.

The Scale of Positive and Negative Experience (SPANE) is widely used to measure emotional experiences, but not much is known about its cross-cultural utility. The present study evaluated the measurement invariance of the SPANE across adult samples (N = 12,635; age range = 18-85 years; 58.2% female) from 13 countries (China, Colombia, Germany, Greece, India, Italy, Japan, Poland, Portugal, Serbia, Spain, Turkey, and the United States). Configural and partial scalar invariance of the SPANE were supported. Three items capturing specific negative emotions (sad, afraid, and angry) were found to be culturally noninvariant. Our findings suggest that the SPANE's positive emotion terms and general negative emotion terms (e.g., negative and unpleasant) might be more suitable for cross-cultural studies on emotions and well-being, whereas caution is needed when comparing countries using the SPANE's specific negative emotion items.

Contraceptive use among low-income urban married women in India.

INTRODUCTION: The reports of a rise in contraceptive practices have not been matched by a similar decrease in population, so there is a need to look into the causes of this discrepancy. AIM: To obtain information from low-income urban married women regarding their contraceptive knowledge, practices, and utilization of the services. MAIN OUTCOME MEASURE: Percentage of low-income urban married women using contraception, different types of contraception used, influence of education on choice of contraception. METHODS: All nonpregnant married women between the ages of 18 and 45 years, belonging to low-income groups were selected for study. Statistical analysis was done using EPI Info ver-5.0. Chi square test was used to test the significance of data. RESULTS: Contraceptive use among these women was 52%; the most common method was tubal ligation. Educated women used spacing methods more often than uneducated women. Women had adequate awareness regarding type of contraceptives available but had no idea about the timing of starting contraception after delivery and about emergency contraception. CONCLUSION: The low-income urban population is aware of the importance of limiting the family size and has family planning facilities yet has less contraceptive usage because of low level of education, increased rate of discontinuation, and lack of proper knowledge of the use of contraception.

Epidemiology and microbiology of nosocomial pediatric candidemia at a northern Indian tertiary care hospital.

The availability and aggressive use of chemotherapeutic and immunosuppressive agents as well as broad-spectrum antibacterial agents have created a large population of patients who are at increased risk of acquiring infections with fungal organisms, especially Candida species. Present work was undertaken to study the epidemiology and microbiology of candidemia and Candida colonization in hospitalized children. A total of 323 suspected cases of septicemia were enrolled, of which blood culture from 7.4% subjects was positive for Candida species. In total, 57.3% subjects were colonized by Candida species at least at one of the tested sites. Of 337 isolates, 24.3, 71.5, 2.9, 0.59, and 0.59% were Candida albicans, Candida tropicalis, Candida krusei, Candida kefyr, and Candida lusitaniae, respectively. Antifungal susceptibility results show that fluconazole, itraconazole, and amphotericin B resistance is prevalent in 18.2, 2.4, and 3.6% of C. albicans isolates, and 21.1, 4.6, and 0.04% of C. tropicalis isolates, respectively. In a large number of cases, source of blood infection was patient's own colonizers, as shown by genetic matching. It was also noted that some strain types are circulating within the ward. High prevalence of non-albicans candidemia with high resistance to fluconazole is prevalent in North Indian hospitalized children.

Yoga an effective strategy for self-management of stress-related problems and wellbeing during COVID19 lockdown: A cross-sectional study.

This cross-sectional research aims to study the effect of yoga practice on the illness perception, and wellbeing of healthy adults during 4-10 weeks of lockdown due to COVID19 outbreak. A total of 668 adults (64.7% males, M = 28.12 years, SD = 9.09 years) participated in the online survey. The participants were grouped as; yoga practitioners, other spiritual practitioners, and non-practitioners based on their responses to daily practices that they follow. Yoga practitioners were further examined based on the duration of practice as; long-term, mid-term and beginners. Multivariate analysis indicates that yoga practitioners had significantly lower depression, anxiety, & stress (DASS), and higher general wellbeing (SWGB) as well as higher peace of mind (POMS) than the other two groups. The results further revealed that the yoga practitioners significantly differed in the perception of personal control, illness concern and emotional impact of COVID19. However, there was no significant difference found for the measure of resilience (BRS) in this study. Yoga practitioners also significantly differed in the cognitive reappraisal strategy for regulating their emotions than the other two groups. Interestingly, it was found that beginners -those who had started practicing yoga only during the lockdown period reported no significant difference for general wellbeing and peace of mind when compared to the mid- term practitioner. Evidence supports that yoga was found as an effective self- management strategy to cope with stress, anxiety and depression, and maintain wellbeing during COVID19 lockdown.
