PurposeThe current study highlights the dark side of a perfectionist leader hindering in business processes and also investigates its impact on procrastination through workplace incivility, psychological distress, and psychological detachment by using the tenet of conservation of resource theory. Positivism research philosophy was adopted, followed by a deductive approach.Design/methodology/approachThe survey technique was used to collect the quantitative data from the employees working in public sector organizations. 364 samples were collected and analyzed using SEM-Mplus techniques, where structured and measurement models were produced and interpreted accordingly.FindingsThe results suggested that perfectionist leaders become a source for their followers to involve in procrastination because of depletion of ego and psychological resources. The results supported the chain of mediation and both paths of perfectionist leaders, workplace incivility, psychological detachment, and procrastination and perfectionist leaders, workplace incivility, psychological distress, and procrastination.Originality/valueThe results and dynamics of the current study provided some meaningful managerial and theoretical implications and future research directions for the researchers. The study contributes significantly to the body of literature since it captures and analyzes the overlooked elements in the context of perfectionist leaders.

“…In particular, the FE model highlighted ductile behaviour with a higher incremental deformation at low loads, whereas it showed lower incremental deformation at high loads. This capacity allowed the structure to better withstand cyclic forces, such as seismic or wind gusts, because part of the energy is dissipated in the deformation work [37]. The FEM analysis highlighted the structure's capacity to withstand wind with a velocity of 72 m•s -1 corresponding to the F3 of the enhanced Fujita Scale (EF Scale) of tornado damage intensity [38].…”

A Highly Sustainable Timber-Cork Modular System for Lightweight Temporary Housing

et al. 2022

In recent years, global society has been subjected to great change due to unpredictable events such as pandemics, migrant flow, urban homeless, wars, and natural disasters. There has been an increased demand for fast and easily constructed buildings characterized by limited space and used for a limited time, modular and flexible self-assembly homes that are reusable without compromising comfort and environmental sustainability. A highly sustainable timber-cork modular system for lightweight temporary housing (LTH) is proposed in this paper. The structure of the proposed LTH was designed as a succession of modular timber portal frames composed of spruce boards hinged together. The concept of the prototype was a full modular shelter. It was possible to interchange every piece of the building, the structural elements, and the walls with each other. Due to the modularity of the elements of which the shelter was composed, this system could offer different solutions to the events above. The proposed LTH was analyzed in terms of its structural, thermal, and environmental performance. The structural system is very reminiscent of the platform frame, characterized by a light load-bearing frame consisting of solid timber uprights and crosspieces connected to the internal frame by means of a mechanical connection. The structural FEM analysis highlighted the structure’s capacity to withstand wind with a velocity of 72 m·s-1, corresponding to the F3 of the enhanced Fujita Scale (EF Scale) of tornado damage intensity. The thermal analysis highlighted a yearly energy use of 430.49 kWh to maintain a set-point temperature indoors of 20-26°C compared with a yearly energy use of 625.93 kWh for a common container house (CH) with the same dimensions under the same environmental conditions. Finally, a Life Cycle Analysis comparison between the proposed LTH and the CH was carried out by means of the One Click LCA software. Two different scenarios of service life were considered: one of 10 years and the other of 5 years. The results highlighted the higher sustainability of the proposed LTH than that of the CH for the required service life (Req SL) period. In particular, the calculated greenhouse gas emissions of the LTH (3.52103 kgCO2 eq) were less than 1/2 of the gas emissions of the CH (8.53103) for a Req SL of 10 years and about 1/3 for a Req SL of 5 years. Furthermore, the LTH showed a value of biogenic carbon storage (7.76E2 kgCO2) about 6 times bigger than the temporary house container (1.31E2 kgCO2). Doi: 10.28991/CEJ-2022-08-10-020 Full Text: PDF

“…Reducing carbon emission and reaching carbon neutrality are the urgent issues to be addressed in construction industry that need the joint efforts from different parties, such as research institutes, manufacturing industries, construction sectors and governments. To struggle toward carbon neutrality, researchers have sought to innovate the high performance construction materials [1][2][3][4][5][6][7][8][9][10][11][12] and structure systems [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] in order to improve the efficiency of engineering structures. In the meantime, the metallurgical industry has sought to develop advanced manufacturing technologies [28][29][30][31] and new steel tubular section profiles, e.g.…”
