A Deep Learning First Approach to Remaining Useful Lifetime Prediction of Filtration System With Improved Response to Changing Operational Parameters Using Parameterized Fully-connected Layer

For the remaining useful lifetime prediction, apart from the normal sensor data which is updated regularly, there are also operational parameters, which do not change during a cycle of operation. Different sets of parameters result in essentially different, but relevant systems and thus require the adaptation from the statistical model for better prediction. We noticed that neural networks could easily overfit into one set of operational parameters and demonstrate constant bias in the prediction for other sets (underfitting). An aspect of major contribution from our work is the use of Parameterized Fully-Connected Layer (PFL). The PFL builds the parameter dependency right into each layer, in this way the parameters act as ”meta-inputs” which adapt the model of neural network models to the different operating conditions. In another aspect of contribution, our work demonstrated that, instead of using feature engineering, convolutional layers could be used to automatically learn the features which are relevant for the prediction. In this way, the deep learning architecture could be reused for different problems or systems. We conduct experiments on the filtration system datasets provided by the Data Challenge 2020 and received results that compare favorably to the prize winners

Predictors of psychological well-being among high school teachers: A cross-sectional study from Southern India

Background: Well-being is increasingly emerging as an important determinant of teacher effectiveness. Aim and objective: To assess the predictors of psychological well-being in Southern India. Settings and design: A cross-sectional study was conducted among 460 high school teachers from government and private schools in Udupi district. Methods and materials: Ryff’s psychological well-being scale (1989) was used. Statistical analysis used: Predictors were identified using logistic regression and p<0.05 was considered to be statistically significant Results: Autonomy, personal growth, positive relations, purpose in life and self-acceptance emerged as predictors of psychological well-being. Age predicted the subdomain of autonomy; number and age of children predicted environmental mastery; gender, monthly income and travelling time of teachers predicted the subdomain of self-acceptance among teachers. Conclusion: Teachers are an important resource whose psychological well-being has not received the attention it is due. An intervention program designed to fit their felt needs may be a step in the right direction

‘No, you should not beat our child because he will become aggressive:’ Applying a multi-method approach to explore intergenerational transmission of parenting practices

Background Exploring the cultural context of intergenerational continuity of warm and harsh parenting informs parents motivations to adopt specific parenting behaviours. Objective Parents’ perceptions of being parented in the past and their current parenting as well as adolescents’ perceptions of current parenting were explored applying a multi-method approach. Methods Following written informed consent, a total of 24 interviews with 10 families (dyads of 14 parents and ten adolescents) from Udupi taluk in southern India was conducted. In the first stage, in-depth interviews were conducted with parent participants (Generation 1 (G1)) and in the second stage, adolescents (Generation 2 (G2)) participated in the photovoice component. Multiple forms of data including photographs, journals and interviews facilitated using the SHOWeD model were collected and were analysed thematically using ATLAS.ti(v.8). Results Subtle changes in reinforcing culture-specific gender norms between generations were elicited. Differences in communication, granting autonomy to female adolescents, and in disciplining methods between G1 and G2 were observed. Warm parenting was transmitted between generations while harsh parenting in G1 in the presence of external social support was discarded in favor of warm parenting in G2. Conclusion We provide evidence for perceptions of parenting and adolescent behaviors across two generations. Transmission of warm parenting and interruption in the cycle of harsh parenting in the presence of external social support were significant findings. Related theoretical and methodological applications are discussed

‘This is the place where I can be alone, no tension:’ Photovoice evidence for adolescent perceptions of their microsystem and psychological adjustment

Adolescents experience myriad emotions which occur in relation to their immediate social space which may shape their perceptions of members within the microsystem. The photovoice method uniquely provides participants with the means to capture their life through the lens of a camera while also enabling them to express emotions and meanings they attach to their particular life situations. We explore the various emotions adolescents attach to the spaces they occupy and how they link them to socialization in the context of the microsystem. This study was conducted in rural and urban areas of Udupi taluk, southern India. A total of 21 participants, ranging from early to late adolescence participated and provided multiple forms of data with 112 photographs, 21 journals on their daily interactions and one-on-one interviews facilitated using the SHOWeD model. The analytical method involved compiling visual data from photographs, journal content and interview data pertaining to each participant as a single data file, developing codes using ATLAS.ti, version 8, and further developing sub-themes and themes as they emerged into narratives. Our study was able to elicit emotions and meanings that adolescents attached to social interactions with gendered nuances specific to the Indian cultural setting. Future applications of the photovoice methodology on research among adolescents have also been discussed
