Personal need for structure and occupational strain: An investigation of structural models and interaction with job complexity

1998

We explored the relation between personal need for structure (PNS), as a global construct and as divided into two components, and occupational strain. Analyses of questionnaire data from two independent samples of Finnish social and health care personnel (n = 3015 and n = 1840) suggest that a high personal desire for structure (DS-component) decreases the risk of psychological strain symptoms, whereas a personal tendency to express negative reactions when one is confronted with a lack of structure (RLS-component) increases this risk. The moderated effect of job context was then tested in a third sample of social and health care personnel (n = 734). The elevated risk of strain in high-RLS em…

Factors associated with innovative climate: what is the role of stress?

1999

We explored the role of occupational stress as a potential determinant of innovative climate by using samples of employees from health care organizations and from enterprises in the metal and retail industries (total N=1767). Factor analyses of the responses to a questionnaire suggested that stress represents a distinguishable element independent of other correlates of innovative climate, including, for example, goal clarity, sufficiency of feedback and communication. In multiple regression analyses, high stress was associated with poor innovative climate but did not moderate the effects of other correlates on innovativeness. The results were reproduced across different samples and differen…

Fragebogen zur Messung der psychosozialen Belastungen bei chronisch-entzündlichen Darmerkrankungen (FBCED): Konstruktion und Evaluation

2002

The "Inflammatory Bowel Disease Stress Inventory (IBD-SI)" measures a broad spectrum of disease-specific every day stress factors in patients with inflammatory bowel disease (IBD). Based on a multistage factor analysis on 300 CED patients, the final form comprises 32 items assigned to 8 different domains: depressed mood, doctor-patient relationship, anxiety about loss of bowel control, occupational impairment, worries about deteriovation, stress from medical treatment, impairment of sexuality/partnership and physical complaints. In addition, a global stress score can be obtained. The reliability values of the 8 subscales with 4 items each indicate a good internal consistency (alpha = 0.76 -…

TCT-663 Comparison of Conformability and Wall Shear Stress Between Resolute Integrity Zotarolimus-Eluting Stent and the XIENCE Xpedition Everolimus-E…

2018

Given its continuous wire molding and sinusoidal design, we hypothesized that Resolute Integrity stent (R-ZES) is more conformable than the XIENCE Xpedition stent (X-EES) and therefore may induce more physiologic wall shear stress (WSS) in angulated coronary arteries. Interim analysis of

Psychosocial safety climate: Conceptual distinctiveness and effect on job demands and worker psychological health

2012

Abstract Psychosocial safety climate is an emerging construct that refers to shared perceptions regarding policies, practices, and procedures for the protection of worker psychological health and safety. The purpose of the research was to: (1) demonstrate that psychosocial safety climate is a construct distinct from related climate measures (i.e., physical safety climate, team psychological safety, and perceived organizational support); and (2) test the proposition that organizational psychosocial safety climate determines work conditions (i.e., job demands) and subsequently worker psychological health. We used samples from two different cultures; an Australian sample (N = 126 workers in 16…

Optimal die Design for Cold Extrusion Processes

1999

The design of cold extrusion processes requires the optimisation of several process variables in order to obtain a defect free product. The fulfilment of different objectives, such as the minimisation of forming loads or the homogeneity of the deformations, is highly requested. Nevertheless, several other relevant aspects of extrusion processes have to be taken into account and require a suitable optimisation of the process parameters and in particular of the die shape. In this paper, tool life has been assumed as the most relevant goal and an effective die design procedure as been setup. It is well known that fatigue cracking of the dies is the principal cause of dies failure in cold extru…

Finite-element simulation of residual stress induced by split-sleeve cold-expansion process of holes

2008

A three-dimensional finite-element simulation was conducted for a split-sleeve cold-expansion process in order to determine the residual stress field around an expanded hole. The commercial FEA software DEFORM-3D™, a Lagrangian implicit code designed for metal forming processes, was used to model the cold-expansion process of a fastener hole. The results show a through-thickness residual stress field in good agreement with the analytical solution developed by Guo. Moreover, the simulation has highlighted the effect of the split sleeve and the plate thickness on the residual stress field. © 2007 Elsevier B.V. All rights reserved.

Sport and Quality of Life

2022

Negli ultimi trent’anni lo sport ha assunto un significato molto rilevante nella vita delle persone e, seppure con notevoli differenze, sia nei paesi a sviluppo economico avanzato, sia in quelli in via di sviluppo. A livello individuale, esso ha costituito un’area di investimento identitario quando ha assunto la forma di sport spettacolo del quale fruire, alimentando la pratica del tifo e il fandom o costituendo il modello di uno stile di vita vincente; ma anche quando ha assunto la forma di pratica del tempo libero attraverso la quale tenersi in forma, facendo crescere, in questo caso, la diffusione di una cultura della salute e del benessere. Si tratta di due modalità di approcciare al co…

but also when he took the form of free time practice through which to keep fit making grow in this case the diffusion of a culture of health and well-being. These are two ways of approaching the consumption of sports by spectators and actorIn the last thirty years sport has taken on a very significant meaning in people's lives and albeit with considerable differences both in advanced economic development countries and in developing countries. On an individual level it constituted an area of identity investment when it assumed the shape of “sport spectacle” to be enjoyed fueling the practice of cheering and fandom or constituting the model of a winning lifestyleand the two ways of use can be strongly related to the perception and assessment of the quality of life. The “semantic universes” which however connote sport and “free time sports” have often appeared polarized. Commercial sport and sports professionalism are intertwined with the institutions of economics politics and culture which above all stress its “spectacularity” in order to capture first and foremost the audience. But also the sport of leisure time is intertwined with the actions of the institutions of economics politics and culture with the difference that these stress above all its “healthy value” aimed at the “healthy and rational” investment of time in an activity which improves the quality of life in the short medium and long period. This polarization between the consumption of sport entertainment - commercial sport - and the consumption of sport as a leisure activity - sport for all - has become increasingly interconnected precisely because of the increased collective identity demand via sport. In other words we have witnessed the spread of shape of sports entertainment that recall the importance of sports for psychophysical well-being for integration and social participation for the reduction of social inequalities ethnic and cultural differences and in which the importance assumed was weakened in the show from agonism from competition from the physical confrontation between two contenders or two teams. A sport in which we act with competitors as well as against competitors. And on the other hand we have gradually witnessed the spectacularization of sports in our free time to the point that the sharing of the results obtained through the declination of a competitive spirit that presents itself as directed no longer against other contenders but against its own performance limits it has become the way in which each person makes part of his or her own life spectacular the one he often considers most authentic. The aim of this work is to describe how the intertwining between the commercial/professional dimension of the sports show and the playful/recreational dimension of sports practice are fueled by a demand and an offer of social identity that characterizes these two “semantic universes”.Settore SPS/07 - Sociologia Generale

The effect of cadmium on oxidative stress in Beta vulgaris

2018

As a heavy metal, cadmium has strongly toxic effects on plants and can induce oxidative stress. It is absorbed by the roots and transported to the stems and leaves. The aim of the study was to evaluate the effect of various concentrations of cadmium on the metabolic activity of Beta vulgaris and assess the dependence of these processes on the content of metal in the plants. To demonstrate the effect of cadmium on metabolism, protein and photosynthetic pigment content, lipid peroxidation, and the activity of enzymes specific for oxidative stress in roots and shoots were measured. Seeds of B. vulgaris were treated with different concentrations of Cd supplied via a CdCl2 solution: 0 (control),…

Prevalence of psychosocial risks in the justice administration staff of the valencian community (Spain)

2016

The objective of the study was to evaluate the psychosocial factors in the work of the justice personnel of Valencia (Spain) to identify the prevalence of psychosocial risks. The participants were 402 workers (28.11 % men) including managers, processors, and social assistants. We assessed using the UNIPSICO questionnaire (includes demand factors, resource factors, and consequences of psychosocial risks). The main risks were work overload (46.02 % of participants in a high risk situation) within the demands; the lack of resources to carry out the work (76.37 % in a high risk situation); and the lack of autonomy (67.41 % in a high risk situation). For the consequences, 61.44 % of participants…
