Interactive effects of past and present environments on overwintering success-a reciprocal transplant experiment
2012
Life-history traits are influenced by environmental factors throughout the lifespan of an individual. The relative importance of past versus present environment on individual fitness, therefore, is a relevant question in populations that face the challenge of temporally varying environment. We studied the interacting effects of past and present density on body mass, condition, and survival in enclosure populations of the bank vole (Myodes glareolus) using a reciprocal transplant design. In connection with the cyclic dynamics of natural vole populations, our hypothesis was that individuals born in low-density enclosures would do better overwintering in low-density enclosures than in high-den…
Application of chemometrics to assess the influence of ultrasound frequency, Lactobacillus sakei culture and drying on beef jerky manufacture: Impact…
2017
The effects of ultrasound (US) frequency, addition of Lactobacillus sakei culture and drying time on key nutritional (protein, amino acids, and organic acids) and physicochemical properties (texture and colour) of cultured and uncultured beef jerky were evaluated. Cultured and uncultured jerky samples were subjected to US frequencies of 25 kHz, 33 kHz and 45 kHz for 30 min prior to marination and drying. Principal component analysis demonstrated a significant effect of beef jerky processing conditions on physicochemical properties. Taurine content of jerky samples was found to increase with an increase in ultrasonic frequencies for cultured samples. No significant changes in colour values w…
Employability and personal initiative as antecedents of job satisfaction.
2009
In a changing and flexible labour market it is important to clarify the role of environmental and personal variables that contribute to obtaining adequate levels of job satisfaction. The aim of the present study is to analyze the direct effects of employability and personal initiative on intrinsic, extrinsic and social job satisfaction, clarifying their cumulative and interactive effects. The study has been carried out in a sample of 1319 young Spanish workers. Hypotheses were tested by means of the moderated hierarchical regression analysis. Results show that employability and personal initiative predict in a cumulative way the intrinsic, extrinsic and social job satisfaction. Moreover, th…
Want a tip? Service performance as a function of emotion regulation and extraversion.
2011
Surface acting and deep acting with customers are strategies for service performance, but evidence for their effectiveness is limited and mixed. We propose that deep acting is an effective strategy for most employees, whereas surface acting's effect on performance effectiveness depends on employee extraversion. In Study 1, restaurant servers who tended to use deep acting exceeded their customers' expectations and had greater financial gains (i.e., tips) regardless of extraversion, whereas surface acting improved tips only for extraverts, not for introverts. In Study 2, a call center simulation, deep acting improved emotional performance and increased the likelihood of extrarole service beha…
Interacciones entre las perspectivas situacionales y disposicionales de meta y el burnout psicológico de los tenistas junior de la élite internaciona…
2009
Resumen Desde el marco de la teoria cognitivo social de las metas de logro en este trabajo se exploran los efectos principales y de interaccion de las orientaciones de meta y del clima motivacional sobre la percepcion de los indicadores del burnout en 225 jovenes tenistas (138 chicos y 87 chicas) de la elite internacional (M edad = 15.7 ± 2.1 anos). Asimismo, se estudia la validez factorial del Eades Athlete Burnout Inventory (EABI), se examina la presencia del burnout y se analiza la relacion entre horas de entrenamiento semanales y el burnout. Los jugadores completaron las versiones inglesas o espanolas del EABI, del TEOSQ y del PMCSQ-2 en diferentes centros de entrenamiento. Los resultad…
Challenging Challenge: The Ambivalent Impact of Challenge on Intrinsic Motivation Effectiveness in Digital Co-Creation
2017
While most literature on co-creation shows a consistently positive impact of challenge on motivational processes, the authors of this study examine situational ambiguous effects. Consequently, the exalted status of challenge in practice and research is called into question. This research combines psychological needs inferred from Self-Determination Theory with challenge derived from Flow Theory to explore direct and interactive effects on motivation and participation in digital co-creation. As an example of concrete consumer innovation the authors applied the concept of Threadless in order to test propositions for co-creation settings. Threadless is a real online platform that calls up for …
Obstacles to intergroup contact: When outgroup partner's anxiety meets perceived ethnic discrimination
2013
Emerging research suggests that outgroup partner's anxiety can disrupt intergroup rapport-building. This study extends previous findings by investigating the interactive effects of anticipated outgroup partner's anxiety and perceived ethnic discrimination on self-anxiety and intergroup contact avoidance. A sample of immigrant adolescents belonging to different ethnic minorities in Italy (N = 118) was considered. Results showed that when participants expected to interact with an anxious outgroup (Italian) versus in-group partner, self-anxiety increased and, as a consequence, their intentions to avoid future encounters. However, these effects were observed only for participants with higher (v…
Independent and interactive effects of thermal stress and mental fatigue on manual dexterity
2020
Many occupations and sports require high levels of manual dexterity under thermal stress and mental fatigue. Yet, multistressor studies remain scarce. We quantified the interactive effects of thermal stress and mental fatigue on manual dexterity. Seven males (21.1 ± 1.3 yr) underwent six separate 60-min trials characterized by a combination of three air temperatures (hot, 37°C; neutral, 21°C; cold, 7°C) and two mental fatigue states (MF, mental fatigue induced by a 35-min cognitive battery; no-MF, no mental fatigue). Participants performed complex (O’Connor test) and simple (hand-tool test) manual tasks pre- and posttrial to determine stressor-induced performance changes. We monitored part…
Geographic, cultural, and psychic distance to foreign markets in the context of small and new ventures
2015
Abstract More often than one might expect, small and new ventures, which already suffer from few resources and a lack of industry legitimacy, take on the additional uncertainties of entry into foreign markets. Some of these foreign entries involve countries that are geographically distant and culturally different from the firm's home country, making foreign market entry all the more difficult and uncertain. Recent studies have criticized prior academic approaches to understanding these difficulties. Insights may be limited if one uses merely the concept of distance and looks primarily for main effects. Entry by new and small ventures into distant foreign markets is complex, and the factors …
PERCEIVED NEIGHBORHOOD VIOLENCE, PARENTING STYLES, AND DEVELOPMENTAL OUTCOMES AMONG SPANISH ADOLESCENTS
2012
This article analyzed perceptions of neighborhood violence of Spanish adolescents (N = 1,015) from authoritative, authoritarian, indulgent, and neglectful families, and its association with three sets of developmental outcomes (psychological, behavioral, and academic). Tests of main and interactive effects were conducted to answer research questions regarding the potential moderating role of perceived neighborhood violence on the relationship between parenting styles and developmental outcomes. Results yielded only main effects of parenting styles and perceived neighborhood violence on developmental outcomes, as well as an interaction between gender and perceived neighborhood violence. Pare…
