The role of task-related antecedents for the development of turnover intentions in temporary project teams
2016
AbstractHigh turnover can cause serious problems in organizations. Yet, previous research confirmed that HRM practices are useful to influence the development of turnover intentions. Existing studies have revealed a variety of factors that drive individuals to leave permanent organizations (POs) but almost no research has considered turnover in temporary organizations (TOs). Yet, TOs, such as project teams, have become increasingly prevalent and exhibit several characteristics that are distinct from POs. Hence, the antecedents of turnover intentions in TOs may also differ from those in POs. However, empirical evidence for this proposition is still lacking. In order to address this research …
Exploring the relationships between high involvement work system practices, work demands and emotional exhaustion: a multi-level study.
2016
This study explores the impact of enacted high involvement work systems (HIWS) practices on employee emotional exhaustion. This study hypothesized that work overload and job responsibility mediate the relationship between HIWS practices (ability, motivation, opportunity and work design HIWS practices) and employee emotional exhaustion. A total of 360 employees (nested within 49 work units) rated their feelings of work overload, job responsibility and emotional exhaustion. The line managers from these work units rated the enacted HIWS practices. Results indicate that ability- and motivation HIWS practices are positively related to work overload, and ability-, motivation- and work design HIWS…
Developing mindful organizing in teams: a participation climate is not enough, teams need to feel safe to challenge their leaders
2020
ABSTRACT Mindful organizing (also known as collective mindfulness) is a collective capability that allows teams to anticipate and swiftly recover from unexpected events. This collective capability is especially relevant in high-risk environments where reliability in performance is of utmost importance. In this paper, we build on current mindful organizing theory by showing how two front-line communication and participatory conditions (perceived safety for upward dissent and climate for employee engagement) interact to predict mindful organizing. We shed light on the controversy around mindful organizing’s effect on team’s subjective experience at work by showing that it leads to…
Internal and External Hiring
2019
Using large-scale, linked, employer–employee, Finnish panel data, the authors examine firms’ internal versus external hiring decisions more comprehensively than has prior literature. The results show that vacancies in job hierarchies are filled more often by horizontal moves than by promotions. Most horizontal moves are external and within the same job functions, so that internally promoted workers face external competitors occupying higher job levels. Compared to internally promoted workers, external and internal horizontal hires have stronger observable ability indicators (e.g., education, experience, prior work history) but weaker job performance in the year preceding the transfer. Inter…
Palladium nanoparticles immobilized on halloysite nanotubes covered by a multilayer network for catalytic applications
2018
The synthesis of pure fine chemicals for industrial purposes is one of the most attractive challenges of chemical research. The use of catalytic pathways mediated by palladium nanoparticles (PdNPs) for C-C bond formation is a useful way to obtain these kinds of compounds. To achieve this objective, the PdNPs can be efficiently loaded on a functionalized natural nanostructured support such as halloysite nanotubes (HNTs). Hybrid materials based on thiol functionalized halloysite nanotubes and highly cross-linked imidazolium salts were successfully developed and used for the stabilization of PdNPs. The HNT/Pd hybrids were thoroughly characterized from a physico-chemical point of view and teste…
Prediction of bone mass gain by bone turnover parameters after parathyroidectomy for primary hyperparathyroidism: neural network software statistical…
2006
Background Primary hyperparathyroidism (pHPT) is the most frequent endocrine hypersecretion disease, and parathyroidectomy is the only curative option, since pharmacologic therapy reduces hypercalcemia but does not impede parathyroid hormone hypersecretion. According to guidelines from the National Institutes of Health, parathyroidectomy is associated with bone mass increase in some asymptomatic patients, while in others bone mass is not changed after surgery. Therefore, we performed the present study in an attempt to elucidate whether a preoperative biochemical bone parameter can be predictive of a significant vertebral bone mass increase in patients with pHPT. Methods For each patient we …
Influence of pillar 3 of pension system on retirement pensions level in Poland : will voluntary part of system enable decent life in old age?
2021
PURPOSE: The aim of this paper is the comparative analysis of the general saving ways included in pillar 3 of the pension system and showing their potential effectiveness from the perspective of the pension system participant. Will the resources allocated by the instruments of the voluntary pension system part significantly improve the level of the future pension? Will they allow a more decent life for an average Polish citizen in the period of the old age?
α-Chymotrypsin-Catalyzed Reaction Confined in Block-Copolymer Vesicles
2010
Herein the reactivity of the enzyme α-chymotrypsin in the confinement of polystyrene-block-poly(acrylic acid) (PS-b-PAA) vesicles was investigated. Enzyme and substrate molecules were encapsulated in PS-b-PAA vesicles with internal diameters ranging from 26 nm to 165 nm during the formation of the vesicles. While the loading efficiencies of enzyme and substrate molecules were practically identical for vesicles of identical size, they were found to increase with decreasing vesicle size. The kinetics of the α-chymotrypsin catalyzed hydrolysis of N-succinyl-Ala-Ala-Phe-7-amido-4-methylcoumarin (AMC) was evaluated following the increase of the absorption of the product 7-amino-4-methylcoumarin …
Patch size and connectivity influence the population turnover of the threatened chequered blue butterfly, Scolitantides orion (Lepidoptera: Lycaenida…
2008
Chequered blue butterfly, Scolitantides orion (Lepidoptera: Lycaenidae) has severely declined in many parts of Europe and is currently red-listed in many countries. We studied the population structure and turnover of the species in a lake-island system in a National Park in eastern Finland over a three-year period. The incidence of the chequered blue on the suitable islands (n = 41) and habitat patches (n = 123) was high: an average of 82% of the islands and patches were occupied over the three year period. At the island scale, the annual population turnover rate was 17%, with an extinction and colonization rate of 7% and 10%, respectively. At the patch scale, the annual population turnover…
Sequential Cross-Sectional Surveys in Orange Farm, a Township of South Africa, Revealed a Constant Low Voluntary Medical Male Circumcision Uptake amo…
2016
Background WHO recommends a male circumcision (MC) prevalence rate higher than 80% to have a substantial impact on the HIV-AIDS epidemic in Eastern and Southern Africa. Orange Farm, a township in South Africa, has a free-for-service voluntary medical male circumcision (VMMC) clinic in operation since 2008. Following an intense campaign from 2008 to 2010, MC prevalence rate increased to 55.4% (ANRS-12126). Ongoing and past VMMC campaigns focused on youths, through school talks, and adults at a community level. The main objective of the study was to assess the change in MC prevalence rate among adults aged 18–19 and 18–49 years in the past 5 years. Methods A cross-sectional survey (ANRS-12285…
