The Impact of Candle Burning During All Saints’ Day Ceremonies on Ambient Alkyl-Substituted Benzene Concentrations

2013

Research findings concerning benzene, toluene, ethylobenzene, meta-, para- and ortho-xylene as well as styrene (BTEXS) emission at public cemeteries during All Saints’ Day are presented here. Tests were carried out at town-located cemeteries in Opole and Grodków (southern Poland) and, as a benchmark, at the centres of those same towns. The purpose of the study was to estimate BTEXS emissions caused by the candle burning and, equally important to examine, whether emissions generated by the tested sources were similar to the BTEXS emissions generated by road transport. During the festive period, significant increases in benzene concentrations, by 200 % and 144 %, were noted at the cemeteries …

Study Crafting and Self-Undermining in Higher Education Students: A Weekly Diary Study on the Antecedents.

2021

The aim of the current study is to validate the adaptation of the job demands–resources theory to the study context. In addition, we introduce the concepts study crafting and self-undermining to the study demands–resources framework by examining the mediating role of engagement and exhaustion in the relationship between study characteristics and study crafting and self-undermining. Over four consecutive weeks, 205 higher education students answered a questionnaire about their weekly study demands and resources, their well-being (i.e., engagement, exhaustion), and their study crafting and self-undermining behaviors. Multilevel structural equation modeling (controlling for autoregressors of m…

Probing the low-temperature chemistry of ethanol via the addition of dimethyl ether

2018

Considering the importance of ethanol (EtOH) as an engine fuel and a key component of surrogate fuels, the further understanding of its auto-ignition and oxidation characteristics at engine-relevant conditions (high pressures and low temperatures) is still necessary. However, it remains difficult to measure ignition delay times for ethanol at temperatures below 850 K with currently available facilities including shock tube and rapid compression machine due to its low reactivity. Considering the success of our recent study of toluene oxidation under similar conditions [38], dimethyl ether (DME) has been selected as a radical initiator to explore the low-temperature reactivity of ethanol. In …

Influència de la qualitat de les relacions interpersonals en el context laboral sobre la “síndrome d’esgotament professional o del cremat” (burnout).

2004

L'objectiu d'aquest estudi és analitzar els nivells de la síndrome d'esgotament professional (SEP) (burnout) en una mostra de policies municipals, i avaluar la influència que els conflictes interpersonals amb els ciutadans, juntament amb el suport social a la feina del supervisor i dels companys, tenen sobre les dimensions de la SEP i sobre la inclinació a l'absentisme. La mostra de l'estudi està formada per 149 policies municipals. La SEP es va avaluar amb el Maslach Burnout Inventory (MBI). Els resultats obtinguts mitjançant anàlisi de regressió stepwise van indicar que la freqüència de conflictes interpersonals amb els ciutadans era un predictor significatiu de les tres dimensions del MB…

Recovery experiences as moderators between psychosocial work characteristics and occupational well-being

2009

Abstract This study examined the direct and moderator roles of recovery experiences (psychological detachment from work, relaxation, mastery, and control) in the relationship between psychosocial work characteristics (i.e. time demands, job control, and justice of the supervisor) and occupational well-being (need for recovery, job exhaustion, and work engagement). The study was conducted among 527 Finnish employees from several occupational sectors who were employed in a variety of different jobs. Of the employees, 53% were women and the average age was 42.4 years. The moderated hierarchical regression analyses showed that psychological detachment and mastery were protective mechanisms agai…

The Role of Personal Biological Resource in the Job Demands-Control-Support Model: Evidence From Stress Reactivity.

2021

Job resources can buffer the deleterious effect of adverse work environments. Extant studies on the interaction pattern between job resources and adverse environments were confined to the diathesis stress model. This traditional perspective has received the challenge from the differential susceptibility model and the vantage sensitivity model. Additionally, stress reactivity may be one of the important job resources at the personal biological level, but its moderating role was short of empirical research. This study aimed to examine how stress reactivity interacts with work environments in predicting job burnouts among 341 Chinese hospital female nurses. This study selected job control and …

Use of cultured human epithelium for coverage: a defect of radial forearm free flap donor site

2010

The radial forearm free flap has been popular in many areas of reconstructive surgery. Despite the many attributes of this flap in maxillofacial reconstruction, one of the disadvantages has been the morbidity of the donor site. Allogeneic cultured epidermis has been successfully applied on large second degree burns and on chronic leg ulcers. Autologous human keratinocytes and fibroblast equivalents can be cultured in-vitro from a small skin sample in order to produce a sufficient amount of epithelial autografts to cover the large defects of third-degree burn wounds. Interestingly, transplanted cultured epidermis retains characteristics of the original donor site. We report a case of a patie…

Immigrant status, gender, and school burnout in Finnish lower secondary school students : A longitudinal study

2017

The aim of this longitudinal study among 9223 students from grade 7 and grade 9 (age 13–14 and 15–16) was to assess whether immigrant status and gender are associated with the level and change (slope) in school burnout among lower secondary school students in the Helsinki metropolitan area. Ninety-seven percent of the variation in school burnout was attributable to individual factors. Both the intercept (2.3, p < 0.001) and slope (0.5, p < 0.001) of school burnout were statistically significant. The slope showed increasing school burnout from grades 7–9. School burnout increased more in girls than in boys. Initially apparent higher school burnout among students who had immigrated to …

The role of parental affection and psychological control in adolescent athletes' symptoms of school and sport burnout during the transition to upper …

2018

Abstract Introduction The transition from compulsory school to upper secondary school is a challenging period for adolescents. Especially challenging it can be for adolescents who aim to integrate two domains of achievement, such as an athletic career and academic education. The pressure from two intertwined achievement domains may make student-athletes vulnerable to symptoms of burnout. The study examined the role of mothers' and fathers’ affection and psychological control as possible risk or protective factors in the symptoms of school and sport burnout among 15–16 year olds adolescent athletes in Finland. Methods The adolescents’ (n = 391) burnout symptoms in the two domains were measur…
