Augmentation of weld penetration by flux assisted TIG welding and its distinct variants for oxygen free copper
2021
Abstract A comparative study to investigate the influences of single component fluxes on the depth-to-width ratio (DWR) of oxygen free copper was carried out with novel variants of tungsten inert gas (TIG) welding namely Activated TIG (A-TIG), Flux Bounded TIG (FB-TIG) and Flux Zoned TIG (FB-TIG) processes. The experiments to identify the fluxes delivering the higher DWRs in A-TIG welding among thirteen distinct fluxes were followed by the trials with FB-TIG and FZ-TIG employing those identified DWR fluxes. The fluxes which outperformed with all the techniques were MoO3 & MgO. Reversed Marangoni and arc constriction mechanisms were perceived to be opt for such an increase in DWR. Metallurgi…
Study of phase transition in Bi3TiNbO9-BaBi2Nb2O9 ceramics
2016
Abstract The subject of the paper is lead free bismuth layer structure oxides (1-x)Bi3TiNbO9-xBaBi2Nb2O9 (x=0; 1; 2; 3 mol). The influence of Bi3TiNbO9/BaBi2Nb2O9 ratio on dielectric and structural properties was studied in a wide range of temperatures. Change in the ratio causes a decrease in the maximum value of dielectric permittivity and shifts the temperature of ε’max to low values, leading to linear decreasing of average grain size and linear increasing of ceramics density. These results indicate an augment of the packing degree and the participation of pores are significantly decreased with the increase of BaBi2Nb2O9 compound intake. Moreover, for 0.7Bi3TiNbO9-0.3BaBi2Nb2O9 ceramics …
Structural characterization and optical constants of p-toluene sulfonic acid doped polyaniline and its composites of chitosan and reduced graphene-ox…
2020
Para-Toluene sulfonic acid doped polyaniline (PANI), PANI/chitosan composites, PANI/reduced graphene-oxide composites and a ternary composite comprising of PANI, chitosan and reduced graphene-oxide have synthesised via oxidative polymerisation of aniline by Ammonium peroxydisulfate (APS). FTIR, XRD, FESEM and UV-VIS techniques were performed for the confirmation of the successful synthesis. The fundamental optical parameters such as, complex refractive index, complex dielectric constants and optical conductivity of the PANI and the composites were investigated in the UV-VIS-NIR range. The results show a clear dependence on the constituent component such as sulphur as well as the absorbance …
Estrategias docentes digitales: una aproximación desde la Didáctica
2019
espanolLa sociedad actual, caracterizada por el impacto de la tecnologia en los diferentes ambitos de la vida cotidiana, construye nuevas formas de hacer, de vivir, de ser, de interactuar, de conocer y de aprender. En este contexto, la escuela no queda al margen de este proceso de cambio e innovacion y se requiere de la puesta en practica de estrategias didacticas digitales para atender a las caracteristicas y demandas del alumnado que escolariza. Sobre ello y, a partir de los resumenes de los articulos que componen el monografico, se realiza un analisis de contenido que ha permitido identificar las palabras de uso frecuente en el ambito analizado, empleando la herramienta Atlas.ti.8 para l…
Investigating occupational well-being and leadership from a person-centred longitudinal approach: congruence of well-being and perceived leadership
2015
The overall objective of this longitudinal study was to investigate the association between perceived leadership and employee well-being from a person-centred approach utilizing the principles of the conservation of resources theory (Hobfoll, S. E. (1989). Conservation of resources: A new attempt at conceptualizing stress. American Psychologist, 44, 513–524; Hobfoll, S. E. (2002). Social and psychological resources and adaptation. Review of General Psychology, 6, 307–324). First, we aimed to identify latent classes (i.e., subgroups) of employees that demonstrated similar mean levels of stability and change in occupational well-being (i.e., vigour and emotional exhaustion) across a mean time…
What drives future business leaders? How work values and gender shape young adults' entrepreneurial and leadership aspirations
2018
Highlights • Work values strongly predict later entrepreneurial aspirations and leadership aspirations. • The pattern of relationships was similar but not identical for both aspirations. • There is a gender gap in both entrepreneurial aspirations and leadership aspirations. • Gender differences in work values contribute to the gender gap in these aspirations. Abstract Who wants to become a business leader? We investigated whether young adults' work values (i.e., the importance placed on different job characteristics and rewards) predict their entrepreneurial aspirations (i.e., the intention to create a venture) and leadership aspirations (i.e., the intention to become a leader in a business…
Antecedents of daily team job crafting
2017
This study investigated potential antecedents of team job crafting defined as the extent to which team members engage together in increasing (social and structural) job resources and challenges, and decreasing hindering job demands. Mindful of the teamwork literature, we hypothesized that individual employee factors (self-efficacy for teamwork, daily affect), team features (team cohesion, climate) and the organizational context of teams (engaging leadership and organizational resources for teamwork) relate positively to daily team job crafting behaviour. Data were collected among 46 multi-professional rehabilitation teams whose members completed two daily surveys after their weekly meetings…
Responsible Leadership in the Manager–Employee Relationship
2020
Research questions:The aim of this study is to explore and conceptualize responsible leadership. The topic is viewed from the viewpoint of the dyadic level between managers and employees. The following research questions are answered: What principles do managers and employees perceive as being significant for responsible leadership in the manager–employee relationship? What social contexts in the relationship call for the principles to occur? To whom do the parties place responsibility for the advancement of the principles?Theory:The study draws on relational leadership theory as well as literature on responsible leadership. Responsible leadership is understood as a dynamic and contextual p…
Leaders’ intensified job demands : Their multi-level associations with leader-follower relationships and follower well-being
2022
To study the ever-increasing pace of work practices, we investigated leader experiences of intensified job demands (IJDs) and their effects on followers. Based on the challenge-hindrance approach, different kinds of job demands may produce either negative or positive work-related outcomes. Using this perspective, we investigated the leaders IJDs against their followers’ satisfaction with them as leaders, follower evaluations of the leader-member exchange (LMX) relationship quality, and their personal well-being (burnout and work engagement). Of the four IJDs, (1) work intensification and (2) career-related planning demands were conceptualised as negative hindrances for leaders, whereas (3) …
A Time to Lead : Changes in Relational Team Leadership Processes over Time
2020
This study analyzes how team members perceive changes in relational leadership processes over time. Interview data from three virtual teams ( N = 18) were analyzed using qualitative thematic analysis. The findings illustrate how ideals of well-functioning leadership and teamwork communication can differ both between and within teams at different times. Team members may perceive benefits of the passage of time in teamwork, including experienced closeness, adjustment, and clarification of practices, as well as challenges such as rigidity and historical baggage. Organizations and teams may experience a shift in the ideals of leadership, but adapting to and adopting new forms of leadership over…
