Item type:Publication, Perceived value as a mediating variable in the theory of planned behavior: Application to the intention of completing a Master of Business Administration(EconJournals, 2020-07-10)The objective of this research is to evaluate the intention to carry out an MBA in the Ecuadorian context through the model proposed by Azjen (1991); including the perceived value; as a mediating variable among the constructs (attitude, subjective norms and perceived behavioral control) and intention. The research was framed in a quantitative perspective, with a cross section. The estimation of the model was made, through the multivariate statistical technique of structural equations, in order to evaluate the relationships between constructs. The analyzed population were undergraduate students from all the Universities of Ecuador, of which a sample of 756 students was surveyed. It was evident that all the hypothetical relationships established in the proposed model are significant with respect to the intention to carry out an MBA. The perceived value for completing an MBA influences the intention to complete an MBA by 0.894. Likewise, the perceived value was evaluated as a mediating variable, concluding in accordance with what was proposed by Ato and Vallejo (2011), which meets the different processes for verification. Finally, the correlations between attitude, subjective norms and control perception were reported to be significant. In addition, the R2 of the dependent variables was determined, hence, the intention to carry out an MBA reported 79.9%; Similarly, the perceived value was determined, obtaining 65.5%.Keywords: Theory of Planned Behavior (TCP); Perceived value; MBA graduate studies; Structural equations.JEL Classifications: M14, M20, M30DOI: 10.32479/irmm.9866 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Posttraumatic growth (PTG) and posttraumatic depreciation (PTD) across ten countries: Global validation of the PTG-PTD theoretical model(Elsevier, 2020-07-06)This study examined the relationships between posttraumatic growth (PTG) and posttraumatic depreciation (PTD) across 10 countries and assessed the factorial invariance of the standardized inventory assessing PTG and PTD, the PTGDI-X, the expansion of the PTGI-X (Tedeschi et al., 2017). We also investigated the roles of social and cognitive factors in PTG and PTD. Data were collected from participants who identified that their most stressful life experience met the definition of trauma in Australia, Germany, Italy, Japan, Nepal, Peru, Poland, Portugal, Turkey, and the US. The participants completed the PTGDI-X and inventories measuring posttraumatic stress disorder symptoms, and predictor variables such as reexamination of core beliefs, centrality of the event, rumination, and disclosures. Results identified universal aspects such as equivalence of factor loadings of the PTGDI-X and the impact of positive/negative disclosure on PTG and PTD. Results also revealed culture-specific aspects, including the relationships between PTG and PTD, and different patterns of cognitive predictors for PTG and PTD. The current study offered the insight that, for the first time using international data, positive and negative post-trauma changes are not likely to be on opposing ends of one dimension, and it is essential to use the PTGDI-X to better understand both positive and negative aspects of post-traumatic experiences. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Development and validation of the theory-driven School Resilience Scale for Adults: Preliminary results(Elsevier, 2020-12-01)Resilience is the ability of an individual or community to adapt to life challenges or adversities while maintaining mental health and well-being. In the multi-systemic resilience paradigm, human development and resilience is embedded in adaptive systems and in their interactions. Although the relationship between school systems and adolescents' mental wellbeing is established, there is no agreement on how to recognize and evaluate the most relevant aspects of the school community, acting at collective level, to boost positive socio-emotional and educational outcomes in children and adolescents. This study presents the development and preliminary validation of a new and theory-driven construct and instrument, the School Resilience Scale for Adults (SRS). School Resilience comprises five interrelated constructs (i.e. Positive relationships, Belonging, Inclusion, Participation, and Mental health awareness) connected theoretically to wellbeing and resilience in children and adolescents. The scale development was theory-driven, and the instrument was tested in four European counties in the frame of the UPRIGHT project (Universal Preventive Resilience Intervention Globally implemented in schools to improve and promote mental Health for Teenagers). Overall, 340 adults participated, 129 teachers and school staff, and 211 relatives of teenagers. The sample was randomly split for two studies: (1) an Exploratory Factor analysis (ESEM), and (2) Confirmatory Factor (CFA) analysis. In the exploratory analysis, Chi-Square difference test and model fit indices point towards the five-factor solution over a three-factor solution. The confirmatory study indicated that a five-factor model (RMSEA = 0.038, CFI = 0.96, TLI = 0.95, SRMR = 0.045) was slightly better than a second-order model (RMSEA = 0.046, CFI = 0.94, TLI = 0.93, SRMR = 0.05). Convergent and discriminant validities were partially demonstrated. Alpha and omega reliability coefficients verified the measurement model of the scale. The results confirmed that a multidimensional construct of School Resilience, defined as a collective resilience factor, embedded in the school staff, family members, and adolescents’ interrelated systems can be characterized and measured. Further studies must determine its role in the promotion of adolescents' resilience, mental wellbeing, educational outcomes, and in their positive adaptation in challenging contexts. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, The role played by supply chain strategies and supply chain integration in financial performance. An empirical study in Peru(Pablo de Olavide University, 2021-12-17)The objective of this study is to develop and test a framework for the role that supply chain strategy (SCS) and supply chain integration have in a firm’s financial performance and to increase the understanding of the role that these factors play in supply chain design. Structural equation modeling was used to test these relationships based on data obtained from small and medium exporting enterprises in Peru. This study responds to a gap in understanding the role of supply chains in small and medium enterprises (SMEs) and how firms in Latin America, especially in Peru, apply supply chain concepts. Findings indicate that companies should prioritize their integration efforts depending on the type of supply chain strategy. Likewise, results show that customer integration is directly related to a firm’s financial performance. This study responds to the need to understand the development of supply chain strategies and the generation of competitive advantage in Peruvian export-manufacturing SMEs. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Shadow of your former self: exploring project leaders’ post-failure behaviors (resilience, self-esteem and self-efficacy) in high-tech startup projects(MDPI, 2021-11-02)Globally, demands for sustainable strategies in the ICT industry have attracted greater momentum as high-tech projects continue to fail in large numbers. Recent studies have underpinned project resilience as a major factor for overcoming these increasing project failures, delays, or ter-mination. However, the complex behaviors of resilient project leaders, especially in post-failure conditions, have been largely overlooked. To address this critical research gap, the present study identifies the direct relationships between three potential behavioral traits of project leaders (i.e., resilience, self-esteem, and self-efficacy) and examines how they move forward beyond project failures. The present study also explored whether self-esteem mediates project leaders’ resilience and self-efficacy. Drawing on data from 232 project leaders in Pakistan’s high-tech start-ups, the new findings suggest that there are significant positive effects of project leaders’ resilience and self-esteem on their self-efficacy, and that project leaders’ resilience and self-efficacy is significantly mediated by their self-esteem. As the project resilience theory gains traction, the present study findings have pinpointed major steps for meeting project challenges ahead of time, allowing leaders and teams to learn from failures, and also for improving organisations’ ability to implement successful and sustainable high-tech projects especially in emerging economies. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Resilience profiles across context: A latent profile analysis in a German, Greek, and Swiss sample of adolescents(Public Library of Science, 2022-01-01)The present study investigated resilience profiles (based on levels of symptoms of anxiety and depression and five dimensions of protective factors) of 1,160 students from Germany (n = 346, 46.0% females, Mage = 12.77, SDage = 0.78), Greece (n = 439, 54.5% females, Mage = 12.68, SDage = 0.69), and Switzerland (n = 375, 44.5% females, Mage = 12.29, SDage = 0.88) using latent profile analyses. We also checked for measurement invariance and investigated the influence of gender and migration on class membership. A three-profile-solution was found for Switzerland (nonresilient 22.1%, moderately resilient 42.9%, untroubled 34.9%), and a four-profile-solution was the best fitting model for Germany (nonresilient 15.7%, moderately resilient 44.2%, untroubled 27.3%, resilient 12.7%) and Greece (nonresilient 21.0%, moderately resilient 30.8%, untroubled 24.9%, resilient 23.3%). Measurement invariance did not hold across the three countries. Profile differences regarding class membership predictions were detected for Germany and Greece, but none for Switzerland. Results implicate that resilience profiles are highly contextually sensitive, and resilience research findings should not be generalized considering the particularity of contexts, people, and outcomes. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Time flies when you are having fun: The mediating effects of project opportunity management in the relationship between project leaders’ self-efficacy and multidimensional project success(SAGE Publishing, 2022-11-01)Numerous studies have linked various leadership styles with project success; however, the role of project leaders’ self-efficacy and project opportunity management has been rarely studied. The present study examines the effects of project leaders’ self-efficacy on multidimensional project success through project opportunity management. Drawing on data of 386 project professionals, the hypothesized relationships were tested using structural equation modeling (SEM) via MPlus. Empirical findings support that project opportunity management helps to explain and predict the relationship between project leaders’ self-efficacy and project success. The study extends project management literature by presenting a new model of multidimensional project success. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, BIM adoption among contractors: A longitudinal study in Peru(American Society of Civil Engineers, 2022-10-17)Building information modeling (BIM) adoption in construction remains a challenge, yet no empirical studies were conducted to gauge adoption behavior changes over time. Such a longitudinal study of BIM adoption would be particularly significant at this pivotal point in the history of construction, as it undergoes a worldwide digital transformation. In some contexts, BIM adoption has been led by contractors without policy intervention; thus, contractors’ adoption behaviors must be understood before policymakers enact top-down interventions for public construction in entire supply chains. Two cross-sectional data sets were collected in 2017 (N=303) and 2020 (N=171) in Lima, Peru, to evaluate changes in a modified technology adoption model (TAM) regarding BIM adoption. Confirmatory factor analysis (CFA), structural equation modeling (SEM), and ANOVA were used to analyze the data. This study shows that contractors adopt BIM if they believe that BIM helps to improve project performance, rather than their own individual performance. Similarly, contractors are concerned with the easiness of implementing BIM in firms and projects rather than the ease of learning BIM. Overall, perceived usefulness to project, perceived ease of implementation, and intention to use BIM had a significant change between 2017 and 2020. Although BIM implementation increased from 25% to 39% at the project level, the adoption at the user level has not significantly changed. This finding suggests that contractors value supply chain/project level implementation benefits rather than successful individual adoption. The results also show that contractors rely on in-house BIM teams or outsourced consultants to carry out BIM-related tasks. However, this would depict a within-firm digital divide between BIM teams and site management. The results are discussed in the context of national change as a BIM policy for public construction was announced by the Peruvian government in 2019. The findings of this research may be used by decision makers to target specific groups of professionals on educational programs. Policymakers could use the findings to inform roadmaps for BIM adoption in Peru and similar countries. - Some of the metrics are blocked by yourconsent settings
