Comparing Subjective With Objective Sleep Parameters Via Multisensory Actigraphy in German Physical Education Students.
2015
This study compared subjective with objective sleep parameters among 72 physical education students. Furthermore, the study determined whether 24-hr recording differs from nighttime recording only. Participants wore the SenseWear Armband™ for three consecutive nights and kept a sleep log. Agreement rates ranged from moderate to low for sleep onset latency (ICC = 0.39 to 0.70) and wake after sleep onset (ICC = 0.22 to 0.59), while time in bed (ICC = 0.93 to 0.95) and total sleep time (ICC = 0.90 to 0.92) revealed strong agreement during this period. Comparing deviations between 24-hr wearing time (n = 24) and night-only application (n = 20) revealed no statistical difference (p > 0.05). As a…
Role of nitric oxide in pheromone-mediated intraspecific communication in mice
2009
Nitric oxide is known to take part in the control of sexual and agonistic behaviours. This is usually attributed to its role in neural transmission in the hypothalamus and other structures of the limbic system. However, socio-sexual behaviours in rodents are mainly directed by chemical signals detected by the vomeronasal system, and nitric oxide is abundant in key structures along the vomeronasal pathway. Thus, here we check whether pharmacological treatments interfering with nitrergic transmission could affect socio-sexual behaviour by impairing the processing of chemical signals. Treatment with an inhibitor of nitric oxide synthesis (Nomega-Nitro-l-arginine methyl ester hydrochloride, L-N…
Isotemporal substitution of inactive time with physical activity and time in bed: cross-sectional associations with cardiometabolic health in the PRE…
2019
Background: This study explored the association between inactive time and measures of adiposity, clinical parameters, obesity, type 2 diabetes and metabolic syndrome components. It further examined the impact of reallocating inactive time to time in bed, light physical activity (LPA) or moderate-to-vigorous physical activity (MVPA) on cardio-metabolic risk factors, including measures of adiposity and body composition, biochemical parameters and blood pressure in older adults. Methods: This is a cross-sectional analysis of baseline data from 2189 Caucasian men and women (age 55-75 years, BMI 27-40 Kg/m(2)) from the PREDIMED-Plus study (http://www.predimedplus.com/). All participants had >= 3…
To join or not to join? Insights from coopetitive RD&I projects
2022
Multipartner research, development and innovation (RD&I) projects are increasingly used to achieve complex innovation goals and keep pace with today's technological imperatives. The involvement of both competing and noncompeting partners increases the complexity of the relationships and poses a challenge to the outcomes of such projects. Therefore, the right choice of partners is particularly important in this context. Although previous research has mainly examined how focal firms deliberately select collaborative partners, this study demonstrates how non-focal firms evaluate invitations to participate in RD&I projects with multiple partners and direct competitors. Going beyond …
Similar but Different? The influence of job satisfaction, organizational commitment and person-job fit on individual performance in the continuum bet…
2022
Permanent organizations and temporary organizations, such as projects, represent two poles of a continuum of organizational temporariness. The literature has shown that organizational temporariness can influence organizational outcomes and employee behavior. Using a sample of 341 members of temporary organizations, we investigate job satisfaction and organizational commitment in a permanent organization and person-job fit in a temporary organization as antecedents of employee performance. We further examine how the degree of organizational temporariness moderates these relationships. The findings show that job satisfaction and organizational commitment negatively influence employee performa…
Eolian and fluvial sedimentation in the southwestern Sinai Mountains, Egypt: a record of flash floods during the late Pleistocene
2012
Wadis emerging from the southwestern Sinai Mountains (Egypt) westwards to the Gulf of Suez are filled by >40 m thick late Pleistocene sediments, which have been subsequently incised to bedrock after the Last Glacial Maximum (LGM). Sedimentation and erosion resulted from changes in the basin's hydrological conditions caused by climate variations. Sediment characteristics indicate distinct processes ranging from high to low energy flow regimes. Airborne material is important as a sediment source. The fills are associated with alluvial fans at wadi mouths at the mountain fronts. Each alluvial fan is associated and physically correlated with the respective sediment fill in its contributi…
The Impact of Business Group Affiliation and Country-Level Institutions on Corporate Governance of Emerging Market Firms
2020
This study outlines how the corporate governance of emerging market firms is influenced by corporate affiliation and institutional embeddedness. We argue that the stronger the business group affiliation, the less likely is the emerging market firm to adopt shareholder value enhancing corporate governance, and that this relationship is moderated by institutional quality and tribalism. Based on189 initial public offerings (IPOs) from 22 African countries between 2000and 2016, we find a significant negative relationship between business group ownership and IPO firms’ quality of corporate governance. We also find this relationship to be significantly negatively moderated by country-level instit…
Closing the sensing-reasoning-actuating loop in resource-constrained WSANs through distributed symbolic processing
2015
Many issues in creating complex applications for pervasive environments are primarily due to the effort required to integrate perception, reasoning and actuating tasks in an efficient and homogeneous way, especially when the underlying infrastructure consists of wirelessly networked embedded devices. To mitigate the complexity of the actual implementation, satisfactory programming paradigms supporting the integration and coordination among heterogeneous devices are required. In this paper we show how a distributed symbolic processing approach that is particularly suited for resource constrained devices, such as the nodes of a Wireless Sensor and Actuator Network (WSAN), may be apt to the pu…
Behavioral reasoning perspectives to brand love toward natural products: Moderating role of environmental concern and household size
2021
Abstract Consumers do not easily trust brands’ claims of naturalness, making it essential to understand the drivers of loyalty and the underlying brand love for such products. Responding to this need, the present study developed a conceptual model based on the Behavioral Reasoning Theory (BRT) to examine the antecedents of brand love. The model was tested using data collected through a cross-sectional survey. The findings suggest that health consciousness is positively associated with reasons for consuming natural products and attitude, which, in turn, are also positively associated with each other. At the same time, reasons for consuming natural products and attitude are positively associa…
Why retail investors traded equity during the pandemic? An application of artificial neural networks to examine behavioral biases
2021
Behavioral biases are known to influence the investment decisions of retail investors. Indeed, extant research has revealed interesting findings in this regard. However, the literature on the impact of these biases on millennials' trading activity, particularly during a health crisis like the COVID-19 pandemic, as well as the equity recommendation intentions of such investors, is limited. The present study addressed these gaps by investigating the influence of eight behavioral biases: overconfidence and self-attribution, over-optimism, hindsight, representativeness, anchoring, loss aversion, mental accounting, and herding on the trading activity and recommendation intentions of millennials …
