Critical Drivers and Barriers of Corporate Social Responsibility in Saudi Arabia Organizations

Luisa PINTO,Alwyia ALLUI 한국유통과학회 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.11

Several studies demonstrate that Corporate Social Responsibility (CSR) is becoming a dominant issue in both research and companies’ management due to stakeholders’ pressure. The identification of internal and external drivers and barriers is an initial stage of the corporate social responsibility implementation. The study aims to identify and analyze the drivers and barriers of CSR in Saudi Arabia’s private organizations. For this purpose, primary data were collected using a survey questionnaire that was administered to a representative sample of companies from different sectors in Saudi Arabia. The results show that the main drivers behind the adoption of CSR among Saudi companies are improvement of corporate image, ethical/moral commitment, and to some extend customers’ requirements and risk management. The findings of this study also suggest that there are important barriers hindering the adoption of corporate social responsibility. Among these, the lack of management commitment and the lack of investors’ interests together with the lack of economic resources and lack of employees’ competencies are the most prominent. The findings of this study not only contribute to a deeper understanding of CSR drivers and barriers, but could also encourage firms’ managers and stakeholders to improve CSR activities for more effective implementation.

Reconsideración sobre el cuento hispanoamericano y su influencia en la literatura chino-taiwanesa

Luisa Shu-Ying, Chang 고려대학교 스페인 라틴아메리카 연구소 2021 스페인라틴아메리카연구 Vol.14 No.2

This research is aimed to study the influence of Latin American literature on Taiwanese literature or literature in Chinese starting from the 1980s. The impact comes mainly from the so-called “magical realism” by the “Group Boom” of the 1960s like Gabriel García Márquez, as well as the short fantastic stories initiated predominantly by Jorge Luis Borges and Julio Cortázar since the 1940s. Current studies on such influence have focused on novels but still very few, let alone other artistic representations or short stories which have aroused great interest from readers. This investigation is intended to look into certain concrete and eminent examples, based on some theoretical studies so as to re-examine the impact and how the great Chinese community has assimilated such theme into local representation. El presente artículo pretende estudiar la influencia de la literatura hispanoamericana en la creación literaria de Taiwán o la literatura en chino a partir de los años ochenta. Dicha influencia se enraíza en el llamado “realismo mágico” por el grupo “boom” de los años sesenta del siglo XX, encabezado por Gabriel García Márquez, así como el género fantástico iniciado muy predominantemente a partir de los años cuarenta por Jorge Luis Borges y Julio Cortázar. Los estudios sobre la huella patente que han dejado estos escritores hispanoamericanos en la literatura chino-taiwanesa van hacia la novela, y siguen siendo escasos, aún menos hacia otras representaciones literarias o artísticas como el cuento o el cine. El presente estudio intenta enumerar algunos eminentes ejemplos concretos, basado en algunos estudios teóricos, como reconsideración de la deuda que deben estos escritores de lengua china y cómo asimilar esa influencia a una representación propia.

Fixed bed column modeling of lead(II) and cadmium(II) ions biosorption on sugarcane bagasse

Luisa Mayra Vera,Daniel Bermejo,Maria Fernanda Uguna,Nancy Garcia,Marittza Flores,Enrique Gonzalez 대한환경공학회 2019 Environmental Engineering Research Vol.24 No.1

In this paper the results of the biosorption of lead(II) and cadmium(II) with sugarcane bagasse in fixed bed columns are presented. Experimental data were fitted to several models describing the rupture curve for single-component and two-component systems. The percentages of removal of lead and cadmium in single-component systems are 91% and 90%, respectively. In lead-cadmium bicomponent systems the percentage of elimination of lead was 90% and cadmium 92%. In single-component systems, Yoon-Nelson and Thomas models successfully reproduce the rupture curves. In two-component system, the Dose-Response model was the best one reproducing the experimental rupture curves in the entire measured range.

Endophytes are microorganisms that asymptomatically invade plant tissues. They can stimulate plant growth and/or provide defense against pathogen attacks through the production of secondary metabolites. Most endophyte species are still unknown, and because they may have several applications, the study of their metabolic capabilities is essential. We characterized 100 endophytes isolated from Espeletia spp., a genus unique to the paramo ecosystem, an extreme environment in the Andean mountain range. We evaluated the cellulolytic potential of these endophytes on the saccharification of the oil palm empty fruit bunch (OPEFB). The total cellulolytic activity was measured for each endophyte on filter paper (FPA). In addition, the specific carboxymethyl cellulase (CMCase), exoglucanase, and β-glucosidase activities were determined. We found four fungi positive for cellulases. Of these fungi, Penicillium glabrum had the highest cellulolytic activity after partial purification, with maximal CMCase, exoglucanase and β-glucosidase enzyme activities of 44.5, 48.3, and 0.45 U/ml, respectively. Our data showed that the bioprospection of fungi and the characterization of their enzymes may facilitate the process of biofuel production.

Graft Copolymerization of 2-Hydroxyethyl Methacrylate onto Chitosan Using Radiation Technique for Release of Diclofenac

Luisa Islas,Guillermina Burillo,Alejandra Ortega 한국고분자학회 2018 Macromolecular Research Vol.26 No.8

Chitosan (CS) was modified with 2-hydroxyethyl methacrylate (HEMA) by gamma radiation to improve its water absorption ability and use it as a drug delivery system. For this, HEMA was grafted by direct method onto dissolved CS (homogeneous) or powder CS (heterogeneous) using doses less than 20 kGy. The grafting percentage was easily controlled changing the homogeneity of system. Low and medium grafting percentages (20-70%) were obtained with the heterogeneous method, while the homogeneous method yielded higher grafting percentages (~340%). CS-g-HEMA was confirmed using infrared spectroscopy (ATR-FTIR), thermogravimetric analyses (TGA) and X-ray diffraction (XRD). In addition, the swelling behaviour, critical pH, and drug absorption, using diclofenac as a model, were also evaluated. Results show that the presence of HEMA had a positive effect on swelling and the drug uptake when low grafting percentages were used; CS-g-HEMA (17%) swelled in water (261%) and loaded better amounts of diclofenac (1.5 mg g-1) than CS (0.97 mg g-1).

The Masculine and the Abject: Defiance of the Stereotypical Orient in M. Butterfly

( Luisa Hyojin Koo ) 21세기영어영문학회 2014 영어영문학21 Vol.27 No.1

Scholars have various approaches to David Henry Hwang`s play M. Butterfly. Some focus on the stereotypical racial images or the reversal of such images within the play (Moy 1990; San Juan 2002; Skloot 1990; Wen 2013). Others analyze the text or its characters using critical or psychoanalytical theories (Deeney 1993; Remen 1994). Still others such as Karen Shimakawa attempt to incorporate critical theory to analyze the cultural aspect of the play, claiming that Song, as national abject, possesses constructed femininity and equally constructed masculinity that is imposed upon him (Shimakawa 2002). While I agree with Shimakawa that M. Butterfly is a story of the masculine power struggle between men on individual and national levels, I do not see Song`s masculinity as untrue and forced upon him. Gallimard`s and Western power domination fantasy ultimately fails when Song threatens the realm of the Western man through his masculine attitude and actual gender. In this paper, I examine the femininity that Song Liling as a cultural abject mimics in order to consciously deconstruct the myth of Western masculinity re-establishment, and question the white norm that Otherizes races that are not white-American.

Social Supply Chain Practices and Companies Performance: An Analysis of Portuguese Industry

Luisa A,PINTO 한국유통과학회 2018 KODISA ICBE (International Conference on Business Vol.2018 No.-

This research aims at studying the internal and external social sustainable practices of eight Portuguese companies and the relationship with economic and social performance. First the author identifies the different social practices based on the literature, after the study builds on the data collected from interviews with eight Portuguese industrial companies`, through 22 semi-structured interviews with general managers, procurement and environmental/safety managers. Secondary data collection was collected from reports, websites and companies internal documentation. Sectors included glass, automotive, drink, wood based panels, furniture and cork. The results indicate that companies’ economic and social performance are affected by the implementation of social practices into the supply chain, namely the internal social practices. The paper is much helpful for the supply chain managers, policy makers to understand the internal and external social practices used by the organizations and how they influenced economic and social performance, and act as a key tool for managers seeking to implement social sustainable supply chain management practices.
