Polyacrylonitrile Precursor

Polyacrylonitrile precursor fiber as the as-spun fiber of carbon fiber plays a vital role in carbon fiber performances. In order to optimize the production process and the fiber performances of polyacrylonitrile precursor fiber, a production parameters optimization approach is proposed to find the relationship between the initial input and the final output of this fiber production and help to determine the production parameters according to the fiber performances required. Because fiber production is a complex industry process with a lot of parameters working together and them all have effect on the final performances, so this optimization is a multi-objective optimization which is based on particle swarm optimization formulas and production data. This approach can maintain the diversity of solutions, improve the accuracy of production parameters determining and provide a optimization of polyacrylonitrile precursor fiber.

The Relationship

The Bodo of the North Eastern region of India have their own kinship system to maintain social relationship since ancient periods. Kinship is the expression of social relationship. Kinship may be defined as connection or relationships between persons based on marriage or blood. In each and every society of the world, social relationship is considered to be the more important than the biological bond. The relationship is not socially recognized, it fall outside the realm of kinship. Since kinship is considered as universal, it plays a vital role in the socialization of individuals and the maintenance of social cohesion of the group. Thus, kinship is considered to be the study of the sum total of these relations. The kinship of the Bodo is bilateral. The kin related through the father is known as Bahagi in Bodo whereas the kin to the mother is called Kurma. The nature of social relationships, the kinship terms, kinship behaviours and prescriptive and proscriptive rules are the important themes of the present study.

This paper discusses the influence of the production parameters on the moisture related comfort characteristics of the compression garments that differ according to the tension applied during the production and elastane count. Correlation analysis, two sided independent t-test analysis and ANOVA tests were applied to analyze the relationship between the production parameters and comfort characteristics which are absorption, vertical and transfer wicking and drying. It was found that tension and elastane composition affect the comfort characteristics by changing the porosity, thickness and the pathways within the fabric.

Mimetic Isomorphism

Megaproject citizenship behavior (MCB) has been confirmed to a play vital role on megaproject performance. Although current research has argued that institution elements have had an impact on MCB diffusion, limited studies have empirically investigated the distinct effectiveness of various institution elements on driving MCB’s widespread diffusion in construction megaprojects. Based on institution theory, this study proposes a theoretical model comprising institutional elements (i.e., normative and mimetic isomorphism), owner’s support, relationship-based trust, and their effect or impact on MCB’s diffusion. Based on 171 industrial questionnaires collected from managers of contractors and designers in megaprojects. Partial least squares structural equation modeling (PLS-SEM) was used to validate the established model. The results indicated that both normative and mimetic isomorphism have positive effects on facilitating MCB diffusion, and owner’s support has shown partial mediation in promoting MCB diffusion through normative isomorphism, as well as full mediation in the promoting of MCB diffusion through mimetic isomorphism. Meanwhile, relationship-based trust exerts a positive moderating effect on the relationship between mimetic isomorphism and MCB. This study extends current literature on driving MCB diffusion from the perspective of institutional theory, contributing by providing four implications for megaprojects managers to “buy in” more extensive MCB.

PurposeThe purpose of this study is to investigate and articulate the performance appraisal process as a tool, used for the development of voice behavior through the fostering of trustworthiness and empowering culture in the organization.Design/methodology/approachData has been collected through survey instruments, filled by employees and their coworkers. The study proposes and tests a new model based on the relationship between performance appraisal and voice behavior through the moderation-mediation mechanism. Data analysis has been performed using SEM through SMART PLS 3.FindingsResults show that a strong and positive relationship exists between performance appraisal and voice behavior through the mediating variable of psychological empowerment. The moderators, empowering leadership and perceived fairness have played vital role in boosting psychological empowerment and strengthening the relationship with performance appraisal.Research limitations/implicationsThe study presents the performance appraisal system as one of the antecedents of employees' voice behavior generated through psychological empowerment (mediator) and perceived fairness and empowering leadership (moderators) since the appraisal system is to be implemented through the leader.Originality/valueThe study presents a unique and innovative idea while it tries to explore and measure the different effects/impacts of the relationship between performance appraisal and voice behavior.

The Capability Approach

"Learning about freedom as freedom to make right choices responsibly is the pivotal task of educational intervention (Chionna 2001). As a practitioner of juvenile penitentiary re-education I experiment it, trying to re-educate young offenders in a prison, where the “capability approach” should be invoked (Sen 2011) and, according to the relational ethics paradigm (Muschitiello, 2012), we teach the young the capacity/ability of choice between alternative life experiences, which should be inspired and embodied by the educational authority of the adults. As agency is a constitutive element of a capability, I wonder: who is the agent? The one who re-educates an inmate? Or the inmate himself? Who should be more efficient and responsible to act in prison? Is it all about specific required competencies that are influenced by the context where penitentiary personnel and inmates act/react reciprocally? Penitentiary educators should adjust their approach, improving their language-as-dialogue tools first, just because the relationship with inmates is based on a dialogic axis. No exception can be made for cultural and linguistic mediators, who are involved in the treatment of foreign inmates (Brancucci 2018). So, I investigate the agency level of penitentiary educators and cultural/linguistic mediators, working together synergistically and/or autonomously. They try to respond to different scenarios, recognizing there is no one-size -fits-all approach to managing cases of re-educational emergencies, and assuming that educational interventions recall a daily presence in the context (Bertolini 1993), especially in prison where people ‘live’ in close proximity (WHO, 2020). But, how to achieve agency when this proximity fades away, or is temporarily interrupted, even turning into a virtual telematic educational approach? The challenge is to transform the consolidated educational-linguistic-dialogic practices into a new bidirectional way to think, act/react (from prison personnel towards inmates and vice-versa), because of the social distance required by the COVID-19 breakthrough."

Evaluation of the toxic effects of a widely used synthetic pyrethroid, deltamethrin (DM), was carried out in this study. This pesticide is preferred for pest control because of its low environmental persistence and toxicity. We investigated the expression pattern of four genes, namely, you ( you), yot ( you-too), momo ( mom) and ubo ( u-boot) during early development of zebrafish, that is, from 12 hpf to 48 hpf stages. These stages are selected as most of the important developmental aspects take place during this period. All four genes are known to play a vital role in development of notochord and somites. To understand the effect of DM on development, embryos of 4 hpf stage were exposed to two concentrations (100 and 200 µg/L) of DM, and observations were made at 12, 24 and 48 hpf stages. Our earlier studies have shown phenotypic abnormalities such as notochord bending, tail deformation, yolk sac and pericardial edema, lightening of body and eye pigmentation and interfered in somite patterning, during these stages of development. Understanding the relationship of phenotypic abnormalities with these four genes has been our primary objective. These four genes were analyzed by Reverse transcription (RT)-polymerase chain reaction and intensity of the bands has shown induction in their expression after exposure to the toxicant. In spite of the expression of genes, it was noticed that DM caused abnormalities. It can be said from the results that translational pathway could have been affected.
