Accessing Antecedents and Outcomes of RFID Implementation in Health Care

This research first conceptualizes, develops, and validates four constructs for studying RFID in health care, including Drivers (Internal and External), Implementation Level (Clinical Focus and Administrative Focus), Barriers (Cost Issues, Lack of Understanding, Technical Issues, and Privacy and Security Concerns), and Benefits (Patient Care, Productivity, Security and Safety, Asset Management, and Communication). Data for the study were collected from 88 health care organizations and the measurement scales were validated using structural equation modeling. Second, a framework is developed to discuss the causal relationships among the above mentioned constructs. It is found that Internal Drivers are positively related to Implementation Level, which in turn is positively related to Benefits and Performance. In addition, Barriers are found to be positively related to Implementation Level, which is in contrast to the originally proposed negative relationship. The research also compares perception differences regarding RFID implementation among the non-implementers, future implementers, and current implementers of RFID. It is found that both future implementers and current implementers consider RFID barriers to be lower and benefits to be higher compared to the non-implementers. This paper ends with our research implications, limitations and future research

On the letter þ in the Greek alphabet used in Bactria

Este trabajo revisa las diferentes teorías sobre el origen del grafema þ con valor silbante en el alfabeto griego utilizado por la dinastía kushán en los territorios de la Bactria helenística a partir del siglo I d. C., alfabeto que notó la lengua bactriana. Basándose en testimonios epigráfi cos y numismáticos, se concluye que probablemente su origen se halla en la modifi cación de la letra griega rho.This paper reviews different theories about the origin of the grapheme þ with sibilant value in the Greek alphabet as used by the Kushan power in Hellenistic Bactria (from the fi rst century BC), to note the Bactrian language. With epigraphic and numismatic evidences, it is concluded that probably its origin lies in the modifi cation of the Greek letter rho

Are black friday deals worth it? Mining twitter users' sentiment and behavior response

The Black Friday event has become a global opportunity for marketing and companies’ strategies aimed at increasing sales. The present study aims to understand consumer behavior through the analysis of user-generated content (UGC) on social media with respect to the Black Friday 2018 offers published by the 23 largest technology companies in Spain. To this end, we analyzed Twitter-based UGC about companies’ offers using a three-step data text mining process. First, a Latent Dirichlet Allocation Model (LDA) was used to divide the sample into topics related to Black Friday. In the next step, sentiment analysis (SA) using Python was carried out to determine the feelings towards the identified topics and offers published by the companies on Twitter. Thirdly and finally, a data-text mining process called textual analysis (TA) was performed to identify insights that could help companies to improve their promotion and marketing strategies as well as to better understand the customer behavior on social media. The results show that consumers had positive perceptions of such topics as exclusive promotions (EP) and smartphones (SM); by contrast, topics such as fraud (FA), insults and noise (IN), and customer support (CS) were negatively perceived by customers. Based on these results, we offer guidelines to practitioners to improve their social media communication. Our results also have theoretical implications that can promote further research in this area

Empirical Evidence of RFID Impacts on Supply Chain Performance

Purpose - The purpose of this paper is to investigate the actual benefits of radio frequency identification (RFID) on supply chain performance through the empirical evidence. Design/methodology/approach - The research reviews and classifies the existing quantitative empirical evidence of RFID on supply chain performance. The evidence is classified by process (operational or managerial) and for each process by effect (automational, informational, and transformational). Findings - The empirical evidence shows that the major effects from the implementation of RFID are automational effects on operational processes followed by informational effects on managerial processes. The RFID implementation has not reached transformational level on either operational or managerial processes. RFID has an automational effect on operational processes through inventory control and efficiency improvements. An informational effect for managerial processes is observed for improved decision quality, production control and the effectiveness of retail sales and promotions coordination. In addition, a three-stage model is proposed to explain the effects of RFID on the supply chain. Research limitations/implications - Limitations of this research include the use of secondary sources and the lack of consistency in performance measure definitions. Future research could focus on detailed case studies that investigate cross-functional applications across the organization and the supply chain. Practical implications - For managers, the empirical evidence presented can help them identify implementation areas where RFID can have the greatest impact. The data can be used to build the business case for RFID and therefore better estimate ROI and the payback period. Originality/value - This research fills a void in the literature by providing practitioners and researchers with a better understanding of the quantitative benefits of RFID in the supply chain

El Estudio de Caso en el contexto de la Crisis de la Modernidad

Con la crisis de la Modernidad como contexto, se presenta en este ensayo una discusión sobre el Estudio de Caso como modalidad de investigación cualitativa. Su fundamentación epistémica incluye elementos marginados o excluidos del paradigma moderno, tales como: la complejidad, el investigador como ente cognoscente y empírico, el actor social como sujeto de la investigación, entre otros rasgos característicos del paradigma emergente. Por otro lado, entre sus implicaciones metodológicas destaca el recurso de la intersubjetividad y en el plano operacional resalta la exigencia de habilidad interpersonal de comunicación y de empatía, así como también de habilidad intelectual para analizar, conceptualizar, interpretar y sintetizar. Se concluye afirmando que la crisis de la Modernidad en la ciencia y las respuestas que se han dado a la misma, han favorecido al Estudio de Caso como una modalidad de investigación de índole cualitativa, en la medida en que el estatus científico del enfoque cualitativo se ha revalorizado
