Using meta-analytic path analysis to test theoretical predictions in health behavior: An illustration based on meta-analyses of the theory of planned…
2016
Objective Synthesizing research on social cognitive theories applied to health behavior is an important step in the development of an evidence base of psychological factors as targets for effective behavioral interventions. However, few meta-analyses of research on social cognitive theories in health contexts have conducted simultaneous tests of theoretically-stipulated pattern effects using path analysis. We argue that conducting path analyses of meta-analytic effects among constructs from social cognitive theories is important to test nomological validity, account for mediation effects, and evaluate unique effects of theory constructs independent of past behavior. We illustrate our points…
Rational Herding in Reward-Based Crowdfunding: An MTurk Experiment.
2020
Crowdfunding is gaining popularity as a way of financing social sustainable initiatives. We performed a controlled economic experiment in MTurk by simulating a crowdfunding platform and developed a theoretical model that rationalizes herding behavior. The experiment was designed to test and quantify the causal effects of revealing specific information to prospective backers: (i) the number of early contributors already financing the project and (ii) positive opinions of other backers versus those of experts. The results show that early contributions to the campaign and positive opinions of peers act as a reinforcing signal to potential backers and affect backers&rsquo
Coping Strategies against peer victimization: differences according to gender, grade, victimization status and perceived classroom social climate
2021
The Sustainable Development Goals (SDGs) include “Good Health and Well-being” (SDG3) and “Quality Education” (SDG4). Nevertheless, many students cannot achieve these goals if they suffer peer victimization at their schools, and intervention programs to reduce it are necessary. These programs should consider the possible differences in the coping strategies preferred by students according to some personal (e.g., gender, grade, victimization status) and contextual (e.g., perceived classroom social climate) factors to be more effective. Therefore, the objective of this study was to analyze the possible differences in the coping strategies preferred by students (ask a friend for help, ask a tea…
Adoption of social media marketing for sustainable business growth of SMEs in emerging economies: The moderating role of leadership support
2021
Social media marketing (SMM) plays an important role in business communication, marketing, operations, and other activities. There is a growing interest among researchers, academicians, and practitioners to understand the role of SMM in business sustainability in small and medium enterprises (SMEs) in an emerging economy, like India. Few studies have attempted to understand this role. Thus, the aim of this study is to examine the impact of adopting social media marketing for sustainable business growth of SMEs in an emerging economy. The study also investigates the moderating role of SME leadership support on the relationship between SMM usage and sustainable business growth of SMEs. After …
Plant Specialized Metabolites in Hazelnut (Corylus avellana) Kernel and Byproducts: An Update on Chemistry, Biological Activity, and Analytical Aspec…
2019
Abstract Corylus avellana (hazelnut) is one of the most popular tree nuts on a worldwide basis. The main products of C. avellana are kernels, a nutritious food, with a high content of healthy lipids, contained in a hard shell. In recent years, along with the ongoing research carried out on hazelnut kernels, a growing interest has been addressed to the hazelnut byproducts including hazelnut skin, hazelnut hard shell, and hazelnut green leafy cover as well as hazelnut tree leaf. These byproducts deriving from the roasting, cracking, shelling/hulling, and harvesting processes have been found as a source of “phytochemicals” with biological activity. The aim of this review is to provide a compre…
Applying an operating model for the environmental risk assessment in Italian Sites of Community Importance (SCI) of the European Commission Habitats …
2013
The fast development of agro-biotechnologies asks for a harmonized approach in risk analysis of GMO's releases, where "risk analysis" entails the assessment, management and communication of risk. Risk assessment consists in the evaluation of the likelihood that a hazard occurs, associated with the presence of the receptor(s) in the receiving environment, and the determination of their potential degree of exposure to the hazard. The whole process has to be both science based and applied case by case, and it involves a very complicated procedure that needs to be transformed in an operational and standardized tool. Beginning in 2003, an expert group on behalf of the Italian Ministry of the Env…
Odonats del País Valencià: diversitat, factors implicats en la composició de les seues comunitats i respostes als senyals de risc durant la fase d'ou
2017
Libèl·lules i espiadimonis són els noms comuns emprats per a anomenar eixos insectes que tan familiars en resulten i que configuren l’ordre escollit per a la realització d’aquesta tesi doctoral: el dels odonats. D’entre les característiques taxonòmiques que el configuren com a grup, cal destacar dos trets diagnòstics: un de la fase adulta i l’altre de la fase larvària. Un és l’òrgan copulador dels mascles adults, el qual s’ubica en el segon segment abdominal; aquesta característica determina un comportament reproductor exclusiu: durant l’aparellament el mascle doblega l’abdomen per a poder arribar a l’orifici genital de la femella. L’altre tret és la modificació del llavi inferior de les la…
Sustainable urban transport policy in emerging countries – case study of Mexico
2015
Negatywne efekty zewnętrzne transportu stanowią bolączkę współczesnych miast, niekorzystnie oddziałując na procesy rozwoju społeczno-gospodarczego. Problemy te są widoczne nie tylko w krajach wysoko czy średnio rozwiniętych – w ogromnym stopniu borykają się z nimi wielomilionowe i wielkopowierzchniowe metropolie, które z kolei są charakterystyczne głównie dla krajów wschodzących, jak np. Chiny, Indie, Brazylia czy Meksyk. Celem artykułu jest przedstawienie wybranych aspektów polityki zrównoważonego rozwoju transportu w stolicy jednego z tych krajów – Meksyku. Autorka starała się również odpowiedzieć na pytanie, w jaki sposób specyficzne uwarunkowania lokalne o różnym charakterze determinują…
The acute effects of different high-intensity conditioning activities on sprint performance differ between sprinters of different strength and power …
2021
The purpose of the present study was to examine the effect of different conditioning activities (CAs) on short-term increase in sprint performance. In twelve male sprinters (21.1+2.6 years, 100 m performance: 11.5+0.6 s) their body composition, half squat maximum strength, 100 m sprinting and countermovement jump performances were evaluated. The performance of a 50 m sprint (splits at 10 m, 30 m and 50 m) was evaluated before and 5, 10 and 15 min after four postactivation performance enhancement CAs on different occasions: [1] 3 sets x 4 s maximum isometric half squat (IHF), [2] 3 sets x 3 consecutive countermovement jumps (cCMJs), [3] 3 repetitions x 30 m overspeed sprinting (OVSP) and [4]…
Heavy-Ion-Induced Degradation in SiC Schottky Diodes : Incident Angle and Energy Deposition Dependence
2017
Heavy-ion-induced degradation in the reverse leakage current of SiC Schottky power diodes exhibits a strong dependence on the ion angle of incidence. This effect is studied experimentally for several different bias voltages applied during heavy-ion exposure. In addition, TCAD simulations are used to give insight on the physical mechanisms involved. peerReviewed
