Why Do Employees Show Pro-Environmental Behaviors? A Perspective of Environment Social Responsibility.

This research uses social identity theory to propose that environmental social responsibility perceptions influence green commitment, and then influence pro-environmental behaviors, which are moderated by institutional pressure. Data were collected from 100 employees of technology firms in Taiwan, and the results support all hypotheses. This research chose technology firms as empirical data because Taiwan's technological level is known to the world, which can reduce sampling errors caused by the lack of environmental knowledge. Finally, this research not only advances the literature on sustainability issues in organizational management but also provides a paradigm to help firms implement pro-environmental behaviors to achieve competitive advantage and sustainable development goals.

How Does Sustainable Leadership Affect Environmental Innovation Strategy Adoption? The Mediating Role of Environmental Identity.

This paper uses social identity theory to develop an environmental identity theory and interpret why sustainable leadership can influence environmental identity, which in turn, results in environmental innovation strategy (EIS) adoption. Data were collected from 90 samples of technology manufacturing firms in Taiwan, and a latent growth curve model was employed to analyze the longitudinal data. The research results confirm all hypotheses. Mediating analysis also supports the environmental identity as a mediating role between sustainable leadership and EIS. Indeed, past studies have not explored the mechanism studied in this paper, a novel mechanism which can not only advance the literature on sustainable development but also help companies to realize sustainable development through environmental innovation strategy adoption.

Transformational Leadership, Ethical Leadership, and Participative Leadership in Predicting Counterproductive Work Behaviors: Evidence From Financial Technology Firms.

Counterproductive work behaviors are a crucial issue for practice and academic because it influences employees' job performance and career development. The present research conceptualizes Kahn's employee engagement theory and employs transformational leadership, ethical leadership, and participative leadership as its antecedents to predict counterproductive work behaviors through a latent growth model. The present research collected empirical data of 505 employees of fintech businesses in Great China at three waves over 6 months. The findings revealed that as employees perceived higher transformational leadership, ethical leadership, and participative leadership at the first time point, they may demonstrate more positive growths in employee engagement development behavior, which in turn, caused more negative growths in counterproductive work behaviors. The present research stresses a dynamic model of the three leaderships that can alleviate counterproductive work behaviors through the mediating role of employee engagement over time.

Synthesis of Alkenylboronates from N-Tosylhydrazones through Palladium-Catalyzed Carbene Migratory Insertion.

The palladium-catalyzed oxidative borylation reaction of N-tosylhydrazones has been developed. The reaction features mild conditions, broad substrate scope, and good functional group tolerance. It thus represents a highly efficient and practical method for the synthesis of di-, tri-, and tetrasubstituted alkenylboronates from readily available N-tosylhydrazones. One-pot Suzuki coupling and other transformations highlight the synthetic utility of the approach. DFT calculations have revealed that palladium-carbene formation and subsequent boryl migratory insertion are the key steps in the catalytic cycle. The high stereoselectivity observed in the formation of trisubstituted alkenylboronates has been explained by distortion-interaction analysis and NBO analysis.

A New Concept of Work Engagement Theory in Cognitive Engagement, Emotional Engagement, and Physical Engagement.

The concept of work engagement (WE) has aroused the interest of many scholars. However, there has been limited academic research in examining how authentic leadership (AL) can influence WE, which consequently influences organizational citizenship behavior (OCB) and task performance (TP). In particular, this study divides WE into cognitive engagement, emotional engagement, and physical engagement to fully reflect the engagement theory. This study introduces three dimensions of WE and tests the theoretical model to validate cognitive engagement, emotional engagement, and physical engagement. Empirical testing using a survey of 151 employees of retail travel agencies in Taiwan revealed that the AL can influence cognitive engagement, emotional engagement, and physical engagement, and also OCB and TP. These analysis results can assist vendors to implement OCB and TP through WE and AL.

The Influence of Green Brand Affect on Green Purchase Intentions: The Mediation Effects of Green Brand Associations and Green Brand Attitude.

This study investigates the impact of green brand affect on green purchase intentions and explores the mediation effects of green brand attitude and green brand associations by means of the structural equation model (SEM). There is no previous literature discussing the relationship between brand affect and purchase intentions from the perspective of green marketing. Therefore, this article establishes a green purchase intention framework to fill in the research gap. The research object of this study focuses on Taiwanese consumers who have the purchase experience of information and electronics products in Taiwan. A total of 1000 consumers were randomly selected and 365 valid responses were received. In addition, this research conducted an empirical study using a questionnaire survey and structural equation model (SEM) to verify the research framework. The results show that green brand affect has no direct influence on green purchase intentions. Besides, this study indicates that green brand associations and green brand attitude fully mediate the relationship between green brand affect and green purchase intentions. It implies that green brand affect indirectly influences green purchase intentions via green brand attitude and green brand associations. While companies tend to raise their customers' green purchase intentions, they need to increase their green brand affect, green brand associations, and green brand attitude.

Corporate Sustainable Development Strategy: Effect of Green Shared Vision on Organization Members' Behavior.

In this study, expectancy-valence theory was used from the perspective of corporate green management to investigate green shared vision (GSV). Moreover, organizational identity theory and psychological ownership theory were combined to propose an integrated conceptual framework. To fill research gaps, an investigation was also conducted with frontline R & D and sales employees to further examine the effect of GSV on organization members' psychology and behavior. The research results indicate that when under the following circumstances, corporate members can enhance organizational citizenship behavior for the environment (OCBE) to improve green management performance, gain the favor of green consumers and achieve sustainable consumption goals. First, enterprises should focus on environmental issues and develop their GSV. Second, enterprises should implement the GSV in different aspects, such as product design, processing, marketing and management. Finally, corporate GSV should be in line with the expectations and values of organization members on environmental issues to motivate their OCBE. Therefore, enterprises must implement their GSV to strengthen the green organizational identity and green product psychological ownership of their members.

Chemo-, Regio-, Diastereo-, and Enantioselective Palladium Allylic Alkylation of 1,3-Dioxaboroles as Synthetic Equivalents of α-Hydroxyketones.

We describe the development of a Pd-catalyzed asymmetric allylic alkylation (Pd-AAA) of acyclic α-hydroxyketones using boronic acids as traceless templates. Condensation of boronic acids with hydroxyketones generates 1,3-dioxaboroles, which can be used directly as pronucleophiles in Pd-AAA reactions. This strategy enables control of the enolate geometry, while removing the issue of O-alkylation. Allylic alcohols can be directly ionized in the presence of Pd(0) and chiral ligands to afford alkylation products with regio- and enantioselectivity. Additionally, a dynamic kinetic asymmetric transformation of allenyl electrophiles affords C-alkylation products in high regio-, diastereo-, and enantioselectivity. To the best of our knowledge, this method represents the first example in Pd-AAA for setting point chirality on a nucleophile simultaneous to stereoinduction on an axial chiral allene.

Palladium-Catalyzed Oxidative Cross-Coupling of Conjugated Enynones with Allylarenes: Synthesis of Furyl-Substituted 1,3-Dienes.

A new method for the synthesis of furyl-substituted 1,3-dienes via palladium-catalyzed oxidative cross-coupling of conjugated enynones with allylarenes is developed. This reaction shows broad substrate scope and good functional group tolerance. Palladium carbene migratory insertion is proposed as the key step for this transformation with conjugated enynones serving as the carbene precursors.

Palladium-catalyzed oxidative borylation of conjugated enynones through carbene migratory insertion: synthesis of furyl-substituted alkenylboronates.

A palladium-catalyzed oxidative borylation reaction of conjugated enynones is developed. This reaction represents a new method for the synthesis of furyl-substituted alkenylboronates. The reaction works well with a series of conjugated enynones. Boryl migratory insertion of the palladium carbene intermediate is proposed as the key step in these transformations.

Palladium-Catalyzed [3+3] Annulation of Vinyl Chromium(0) Carbene Complexes through Carbene Migratory Insertion/Tsuji-Trost Reaction.

Vinyl chromium(0) Fischer carbene complexes were employed as the source of π-allylic palladium species for catalytic [3+3] annulation under palladium catalysis. Mechanistically, this transformation is proposed to involve carbene migratory insertion and intramolecular Tsuji-Trost reaction as the key steps. Substituted six-membered heterocyclic flavonones and quinolines are obtained, depending on the nucleophilic functional group on the coupling partners.

Colcemid inhibits the rejoining of the nucleotide excision repair of UVC-induced DNA damages in Chinese hamster ovary cells.

In our previous study, we found that colcemid, an inhibitor of mitotic spindle, promotes UVC-induced apoptosis in Chinese hamster ovary cells (CHO.K1). In this study, a brief treatment of colcemid on cells after but not before UV irradiation could synergistically reduce the cell viability. Although colcemid did not affect the excision of UV-induced DNA damages such as [6-4] photoproducts or cyclobutane pyrimidine dimers, colcemid accumulated the DNA breaks when it was added to cells following UV-irradiation. This colcemid effect required nucleotide excision repair (NER) since the same accumulation of DNA breaks was barely or not detected in two NER defective strains of CHO cells, UV5 or UV24. Furthermore, the colcemid effect was not due to semi-conservative DNA replication or mitosis since the colcemid-caused accumulation of DNA breaks was also seen in non-replicating cells. Moreover, colcemid inhibited rejoining of DNA breaks accumulated by hydroxyurea/cytosine arabinoside following UV irradiation. Nevertheless, colcemid did not affect the unscheduled DNA synthesis as assayed by the incorporation of bromodeoxyuridine. Taken together, our results suggest that colcemid might inhibit the step of ligation of NER pathways.
