Exploring the Impact of a Hotel’s Rating and Number of Reviews through Online Transactions  [PDF]
Shinn-Nen Jenq
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105401
In recent years, much has been said about online consumer-generated feedback. Concern typically emerges regarding consumer decision-making as well as the preservation of an organization’s image. Additionally, a company’s financial performance can be affected by customer online ratings. The present study explores the impact of a hotel’s rating and the number of reviews on the value generated through online transactions. The research team gathered a sample of 178 hotels representing various companies and brands within Taiwan. Research results demonstrate that TripAdvisor ratings as well as the number of reviews had positive relationship with the average size of each online booking transaction. The paper concludes with theoretical and practical implications.
Both PKA and Epac Pathways Mediate N-Acetylcysteine-Induced Connexin43 Preservation in Rats with Myocardial Infarction
Tsung-Ming Lee, Shinn-Zong Lin, Nen-Chung Chang
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0071878
Abstract: Cardiac remodeling was shown to be associated with reduced gap junction expression after myocardial infarction. A reduction in gap junctional proteins between myocytes may trigger ventricular arrhythmia. Therefore, we investigated whether N-acetylcysteine exerted antiarrhythmic effect by preserving connexin43 expression in postinfarcted rats, focusing on cAMP downstream molecules such as protein kinase A (PKA) and exchange protein directly activated by cAMP (Epac). Male Wistar rats after ligating coronary artery were randomized to either vehicle, or N-acetylcysteine for 4 weeks starting 24 hours after operation. Infarct size was similar between two groups. Compared with vehicle, cAMP levels were increased by N-acetylcysteine treatment after infarction. Myocardial connexin43 expression was significantly decreased in vehicle-treated infarcted rats compared with sham operated rats. Attenuated connexin43 expression and function were blunted after administering N-acetylcysteine, assessed by immunofluorescent analysis, dye coupling, Western blotting, and real-time quantitative RT-PCR of connexin43. Arrhythmic scores during programmed stimulation in the N-acetylcysteine-treated rats were significantly lower than those treated with vehicle. In an ex vivo study, enhanced connexin43 levels afforded by N-acetylcysteine were partially blocked by either H-89 (a PKA inhibitor) or brefeldin A (an Epac-signaling inhibitor) and completely blocked when H-89 and brefeldin A were given in combination. Addition of either the PKA specific activator N6Bz or Epac specific activator 8-CPT did not have additional increased connexin43 levels compared with rats treated with lithium chloride alone. These findings suggest that N-acetylcysteine protects ventricular arrhythmias by attenuating reduced connexin43 expression and function via both PKA- and Epac-dependent pathways, which converge through the inactivation of glycogen synthase kinase-3β.
Contextos comunitários favoráveis ao bem-estar
Análise Psicológica , 2007,
Abstract: this chapter identifies "context minimization error" as the tendency to ignore the impact of enduring neighbourhood and community contexts on human behaviour. the error has adverse consequences for understanding psychological processes and efforts at social change. the chapter describes a series of theoretical models of how neighbourhoods and community settings are associated with various aspects of human welfare and reviews evidence of associations of context with health, psychological distress, risk behaviours, psychological attitudes, and child development. it suggests that many psychological processes may play out differently in different contexts and that contextual factors interact with socio-cultural characteristics of individuals in predicting outcomes. people, in turn, can shape community contexts. a more sophisticated understanding of the effects of contexts depends on more sophisticated approaches to assessing them.
Desencantamento da modernidade e da pós-modernidade: diferencia??o, fragmenta??o e a matriz de entrela?amento

Abstract: in many significant quarters, the tone and substance of sociological discourse on the past, present and future of culture at large, institutions, content of individual pursuits and relations, and about the matter and organization of science, technology and epistemology has changed appreciably. post-modern society discourse, and correspondingly supportive intellectual and social phenomena, offer some credence to arguments that the world of today and the prospects of tomorrow stand in radical contrast or even asymmetry with the world of the past two and a half centuries. the purpose of this article is threefold. first, it is necessary to identify the specific domains in which post-modern claims differ from dominant notions of the modernity representation of society and science. in what ways do post-modernity portrayals substitute and repudiate modernity concepts, and alternatively, to what degree do they instead seek to build on them taking into account recent cognitive, technological and societal shifts, yet still within a modernity framework? second, what constitutes the foundational cultural and cognitive message of post modernity? where does the message authentically break with modernity, and where does it distinctly seek to destroy the very foundations of modernity thinking? what are the putative implications for science, technology, and for epistemology itself? finally, an alternative to post-modern analysis will here be advanced, an alternative that draws on basic features of modernist thinking, yet which incorporates events that have undeniably transform man, machine, material and epistemology over the last several decades, and which thus redraws the modernity map by specifying alternative components and modes of interaction and extension. this hypothesis may be interpreted as a bridge and deviation from both classical and post modernity. this line of thought may be clumsily labeled for the moment "post post modernity". the hypothesis is ground on an "interlac
Regimes de produ??o e difus?o de ciência: rumo a uma organiza??o transversaldo conhecimento

Abstract: this article is a contribution to the critical sociology of science perspective introduced and developed by pierre bourdieu. the paper proposes a transversalist theory of science and technology production and diffusion. it is here argued that science and technology is comprised of multiple regimes, where each regime is historically ground, possesses its own division of labour, modes of cognitive and artefact production and has specific audiences. the major regimes include the disciplinary regime, utilitarian regime, transitory regime and research-technology regime. concepts, materials and practitioners circulate between the regimes. though each regime is autonomous, they are simultaneously closely interlaced. in science and technology, autonomy is not antithetical to interdependence and reciprocity. this study demonstrates for the four specified regimes of production and diffusion that differentiation is not contrary to integration. in science, differentiation and integration comprise two sides to the same coin. this analysis focuses strongly on the research-technology regime, as it comprises the principal structure of transversality that promote convergence and complementarity on the disciplinary, transitory and utilitarian regimes by dint of the trans-boundary movement of cognitive, material and epistemological generic instrumentation. this generic instrumentation gives rise to a "lingua franca" in science and to "pragmatic universality".
Crafting a Real-Time Information Aggregator for Mobile Messaging
Jenq-Shiou Leu
Journal of Computer Networks and Communications , 2010, DOI: 10.1155/2010/209617
Abstract: Mobile messaging is evolving beyond SMS (Short Message Service) text messaging with the introduction of MMS (Multimedia Messaging Service). In the past, such a scheme is used for peer-to-peer communication. Messages are generally displayed on a cellular phone with a limited-sized screen. However, such a visualizing process is not suitable to broadcast real-time SMS/MMS messages to people in public. To facilitate the instancy and publicity, we develop a real-time information aggregator—Visualizing SMS and MMS Messages System (VSMMS)—to realize the concept by integrating SMS and MMS messaging over GSM/GPRS/UMTS onto a remote display device. The device exhibits messages on a larger display device in public. VSMMS features a revolutionized variation of mass media broadcasting. In this paper, we practically illustrate how to design and implement VSMMS and use a M/M/1 model to conduct a theoretical analysis about the message delay in the system queue. Meanwhile, we make an empirical performance evaluation about the message transmission time over different networks.
Forecasting telecommunication new service demand by analogy method and combined forecast
Lin Feng-Jenq
Yugoslav Journal of Operations Research , 2005, DOI: 10.2298/yjor0501097l
Abstract: In the modeling forecast field, we are usually faced with the more difficult problems of forecasting market demand for a new service or product. A new service or product is defined as that there is absence of historical data in this new market. We hardly use models to execute the forecasting work directly. In the Taiwan telecommunication industry, after liberalization in 1996, there are many new services opened continually. For optimal investment, it is necessary that the operators, who have been granted the concessions and licenses, forecast this new service within their planning process. Though there are some methods to solve or avoid this predicament, in this paper, we will propose one forecasting procedure that integrates the concept of analogy method and the idea of combined forecast to generate new service forecast. In view of the above, the first half of this paper describes the procedure of analogy method and the approach of combined forecast, and the second half provides the case of forecasting low-tier phone demand in Taiwan to illustrate this procedure's feasibility.
Analysis of Leading Economic Indicator Data and Gross Domestic Product Data Using Neural Network Methods
Edward Tirados,John Jenq
Journal of Systemics, Cybernetics and Informatics , 2009,
Abstract: In this report, Leading Economic Indicator (LEI) data and Gross Domestic Product (GDP) data have been analyzed to determine if changes in the ten indicators can be used to predict changes in GDP. Three neural network methods and one statistical method were used to complete the analysis. For this project, the intent was to use multiple regression and backpropagation to develop correlations in which LEI values are used to predict the GDP change in the following quarter. Alternatively, Kohonen's self-organizing map and hierarchical clustering were used to group months of LEI data into clusters to determine if months in a cluster (and thus months with similar LEI values) also have similar changes in GDP.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0030337
Abstract: Background Effects of long-term glucose load on peritoneal dialysis (PD) patient safety and outcomes have seldom been reported. This study demonstrates the influence of long-term glucose load on patient and technique survival. Methods We surveyed 173 incident PD patients. Long-term glucose load was evaluated by calculating the average dialysate glucose concentration since initiation of PD. Risk factors were assessed by fitting Cox's models with repeatedly measured time-dependent covariates. Results We noted that older age, higher glucose concentration, and lower residual renal function (RRF) were significantly associated with a worse patient survival. We found that female gender, absence of diabetes, lower glucose concentration, use of icodextrin, higher serum high density lipoprotein cholesterol, and higher RRF were significantly associated with a better technique survival. Conclusions Long-term glucose load predicted mortality and technique failure in chronic PD patients. These findings emphasize the importance of minimizing glucose load in PD patients.
Independence Numbers in Trees  [PDF]
Min-Jen Jou, Jenq-Jong Lin
Open Journal of Discrete Mathematics (OJDM) , 2015, DOI: 10.4236/ojdm.2015.53003
Abstract: The independence number \"\" of a graph G is the maximum cardinality among all independent sets of G. For any tree T of order n ≥ 2, it is easy to see that \"\". In addition, if there are duplicated leaves in a tree, then these duplicated leaves are all lying in every maximum independent set. In this paper, we will show that if T is a tree of order n ≥ 4 without duplicated leaves, then \"\". Moreover, we constructively characterize the extremal trees T of order n ≥ 4, which are without duplicated leaves, achieving these upper bounds.
