This paper aims to analyze the companies’ view about the financial valuation of intangibles relevance and its influence on corporate performance. Based on the theory of resources, the role of intangibles in business competitiveness is justified. The traditional factors of production have become secondary, while the success is primarily based on the development and utilization of intangible resources. One of the main problems in managing the intangibles appears to be that, there is a general lack of information about them. Therefore, financial valuation of intangibles will result in significant benefits to the organization that will help determine business strategy, process design as well providing competitive advantage. It follows the hypothesis of this work, the greater known about their intangibles and the greater sensitivity to the financial valuation of them, the better performance. To achieve this objective, a field study is done, doing telephone calls to Basque Country companies’ financial managers. 相似文献

Consumer reactance appears to be a major inhibiting result in the personalization paradox of online personalized advertising. The objective of this study is to uncover consumer reactance of online personalized advertising. We identify the rational choice factors rooted in the rational choice theory from a negative-effect perspective and examine their impacts on consumer reactance with consideration of affective factors. Our results confirm that three rational choice factors from a negative-effect perspective have significant impacts on consumer reactance, and affective factors such as ownership and vulnerability are dominant determinants of these rational choice factors. The effects of these affective factors on consumer reactance can be mediated by individual rational choice factors. The findings provide a new perspective on the paradox phenomenon and offer online personalized advertising providers new approaches to improving their performance. 相似文献

Social commerce, a recent branch of e-commerce, has made the experience of consumers on social commerce platform (SCP) different from other contexts, as the consumers have social interactions with each other. Growing evidence also shows that consumers on these platforms are prone to impulse buying behavior owing to the social interactions. However, existing research on online impulse buying was limited when illustrating the behavior of consumers on SCPs as social relationship constructs were not included. New theoretical developments are needed in regard to fill the research gap. In this research, parasocial interaction (PSI) theory is introduced in this research to examine the influence of social relationship factors on the formation of impulse buying behavior. An empirical research has been conducted on Mogujie (www.mogujie.com), one of the most popular image-sharing SCPs in China. Results indicate that PSI exerts an impact on impulse buying tendency, the social-relevant features of the SCP determine PSI, and perceived usefulness and PSI both significantly affect perceived enjoyment. In addition, consumers’ perceived enjoyment and impulse buying tendencies significantly affect their urge to buy impulsively. The implications, limitations, and discussions are provided. 相似文献

The purpose of this research is to explore the factors that influence a consumer before installing a mobile application. A research model is created based on perceived risk, trust, perceived benefit, and intent to install. Seven antecedents of trust and risk include perceived security, perceived reputation, application characteristics, familiarity, desensitization, consumer disposition to trust, and consumer disposition to risk. Partial least squares (PLS) is used to test the research model. Only significant antecedents are retained and a new research model is created, which includes the antecedents of perceived security and familiarity. Results show that consumers that perceive more security have greater trust and reduced perceived risk. Furthermore, consumers that feel more familiar with finding, purchasing, downloading, and installing applications have greater trust and reduced perceived risk. More than half (R2=.505) of the variability in the intention to install an app is explained. 相似文献

The rise of social media has created a new e-commerce platform called social commerce. In social commerce, e-vendors such as Amazon may integrate social media with their traditional e-commerce sites. Based on self-determination theory and social commerce literature, we develop a model illustrating how social commerce features may impact consumer behaviors and facilitate social commerce benefits from the extrinsic motivation perspective. We identify four types of extrinsic motivation including external motivation, introjected motivation, identified motivation, and integrated motivation; and we examine their influences on consumers’ intention to contribute social commerce information, which in turn leads to their subsequent behaviors and increases the perceived benefit of social commerce. We also consider the moderating effect of gender in the formulation of social commerce benefits. Based on longitudinal survey data from Amazon consumers, we find that 1) consumers’ external and identified motivation has a positive impact on intention to contribute social commerce information; 2) consumers’ intention is positively associated with their future behaviors, which in turn facilitate their perceptions of social commerce benefits; and 3) gender moderates the impact of behavior on social commerce benefits. 相似文献

Conclusion This is a challenging book and it addresses important questions. This review has focused on what I think is the most important
question of all: just what is the relationship between the ‘strategies’ which drive modern science and the social values which
guide the societies we live in. I have much sympathy with the way in which Lacey tries to answer this question and how he
tries to open up alternative possibilities and give us a view of the future which is not just a continuing catalogue of environmental
disaster ‘for the relief of man's estate’. However, I have expressed doubts as to whether he has been entirely successful
in this regard, especially concerning the alternatives to the materialist strategies. 相似文献

Online social media is transforming the way customers communicate and exchange product information with others. Consumers increasingly rely on the opinions and recommendations from social media members when making purchasing decisions. However, information received from social media may have different meanings and social implications for consumers. Based on the theory of informational social influence and heuristic-systematic model (HSM), we develop a model to understand the relative importance of informational social influence, normative social influence, and perceived information quality on the consumer’s social shopping intention under different levels of product involvement. The results of the structural equation modeling (SEM) using a sample of 503 consumers in the Facebook brand fan pages indicate that social influences have a greater impact on the consumer’s social shopping intention than perceived information quality. Three social interactional factors (perceived similarity, familiarity, and expertise) have a positive effect on social shopping intention via the mediation of informational, normative social influence and perceive information quality. The multiple-group analysis suggests that high product-involved consumers are motivated to exert more cognitive effort to evaluate the product information. In contrast, low product-involved consumers are more susceptible to informational social influence. We draw on these findings to offer implications for researchers and practitioners. 相似文献

This paper explores varying configurations of knowledge in organisations. A multi-dimensional framework of distinctive forms of knowledge is used to highlight different patterns of organisational knowledge, demonstrating their heterogeneity and variability – over time, in terms of depth of expertise, and their distribution within and between organisations. Common knowledge that is shared across an organisation accounts for only a small proportion of organisational knowledge, indicating that strategies to exploit this resource for competitive advantage will be constrained unless mechanisms are developed that enable access to and transfer of knowledge that is not yet shared or common. 相似文献

Parkinson’s disease (PD) is an old age disorder of basal ganglia which involves oligomerization of α-synuclein protein and formation of intercellular inclusions known as “Lewy bodies” in substantia nigra and caudate nuclei in brain which is progressive in nature. It is second most prevalent neurodegenerative disorder characterized by tremor at rest, muscle rigidity, slowness of movement (bradykinesia, akinesia), and changes in posture (instability). Both excess and deficiency in levels of transition metals (especially iron, copper) can be detrimental to the central nervous system. Abnormalities in iron (Fe) and copper (Cu) metabolism have been reported to produce oxidative stress which is one of the major cause in pathogenesis of PD. In the present study 35 PD patients and 33 controls of Northern Indian population were included and serum levels of Fe, Cu and ceruloplasmin (Cp) were measured. Serum Fe (p < 0.01) and Cu (p < 0.01) levels were found to be significantly decreased in PD, whereas there was no significant change in Cp levels in PD patients as compared to controls. These results suggest the existence of a defect in iron which over the time, may hasten the entry of iron into the brain and decrease iron in the extracellular compartment in PD patients. 相似文献

This paper investigates the effects of standard-essential patents (SEPs) to identify strategic differences between firms in advanced countries and those in latecomer countries. By comparing the SEP data-sets of incumbent and catch-up groups of the top 10 SEP firms, this paper has discovered the following four main findings. First, SEP strategic manoeuvres work as an effective way of expanding the sphere of catch-up firms’ influence. Particularly after passing a certain threshold, catch-up firms’ technological influence increases in an exponential manner. Second, for incumbent firms, SEP strategic manoeuvres serve as a catalyst to deepen the development of self-reliant trajectories embodied in the history and future of standards. Third, catch-up firms have specialised in short cycle technologies for self-reinforcing capability. Fourth, the effects of SEP strategic manoeuvres and international protection size on the likelihood of SEP litigation are greater for catch-up firms than for incumbent firms. These findings highlight the dual role of standards-setting organisations (SSOs) for catch-up firms (i.e., knowledge-learning and knowledge-diffusion spaces). For incumbent firms, these findings stress the importance of establishing reinforcing mechanisms to align long-standing self-reliant knowledge paths with the direction of anticipatory standardisation. This discovery provides strategic insights within the context of post catch-up strategy. 相似文献

A high circulating concentration of the non proteinogenic amino acid homocysteine has been implicated as a risk factor for Alzheimer’s Disease and its prodromal stage, mild cognitive impairement. Furthermore, hyperhomocysteinaemia has been directly attributed to a deficiency in vitamins B12, folate, and B6. Several studies have demonstrated decrease in progression of mild cognitive impairement to Alzheimer’s Disease, and some have even shown an improvement in cognition after vitamin supplements with B12 and folate. Plausible mechanisms linking hyperhomocysteinaemia to Alzheimer’s and cognitive impairement have been hypothesized and demonstrated in hyperhomocysteinemic mice models. However, some studies have not elucidated any benefit of vitamin supplements in subjects with cognitive impairment. Hence, multicentric clinical studies need to be conducted to substantiate the mechanisms of neuronal degeneration due to hyperhomocysteinaemia and to demonstrate the beneficial effect of folate, B6 and B12 supplements on cognition. 相似文献

I describe the emergence of Floridi’s philosophy of information (PI) and information ethics (IE) against the larger backdrop of Information and Computer Ethics (ICE). Among their many strengths, PI and IE offer promising metaphysical and ethical frameworks for a global ICE that holds together globally shared norms with the irreducible differences that define local cultural and ethical traditions. I then review the major defenses and critiques of PI and IE offered by contributors to this special issue, and highlight Floridi’s responses to especially two central problems – the charge of relativism and the meaning of ?entropy’ in IE. These responses, conjoined with several elaborations of PI and IE offered here by diverse contributors, including important connections with the naturalistic philosophies of Spinoza and other major Western and Eastern figures, thus issue in an expanded and more refined version of PI and IE – one still facing important questions as well as possibilities for further development. 相似文献

This paper aims at rejuvenating the two rank correlation coefficients, Spearman’s footrule (SF) and Gini’s gamma (GG), which were forgotten in the literature for a long time due to lack of knowledge concerning their statistical properties. Under the common bivariate normal model, we establish the asymptotic analytical expressions of the mean and variance of SF and GG, and investigate the performances of SF and GG from the aspects of biased effect, approximate variance and asymptotic relative efficiency (ARE). Moreover, we further study the robustness of SF and GG under contaminated normal models. In order to get a deeper understanding of their performances, we also compare SF and GG with Kendall’s tau (KT) and Spearman’s rho (SR), the most widely used rank correlation coefficients, in terms of bias and mean square error (MSE) under both the normal and contaminated normal models. Finally we show an application of SF and GG in the field of signal processing through the example of time-delay estimation. Simulation results indicate that SF and GG outperform SR and KT in some cases. The new findings discovered in this paper enable SF and GG to play complementary roles to KT and SR in practice. 相似文献

Customers’ acceptance of artificially intelligent service robots: The influence of trust and culture
This study addresses two critical research gaps in human-robot interaction (HRI): the limited systematic research on the role of trust in customers’ acceptance of artificially intelligent (AI) robots; and the lack of understanding of robot acceptance under different cultural backgrounds. Drawing on the AIDUA framework, this study examines the impacts of trust and moderating effects of both national (the U.S. and China) and individual culture on customers’ intentions to use AI robots in hospitality services by developing a theoretical model. The model is tested on data collected using online data collection platforms from 491 U.S. and 495 Chinese respondents. PLS-SEM and the bootstrapping method were used to test the hypothesized relationships and analyze the moderating effects of culture, respectively. The findings suggest that trust in interaction with AI robots is a significant higher-order construct that influences the intention of use. Furthermore, uncertainty avoidance, long-term orientation, and power distance have been found to exhibit significant moderation effects. The results of this study extend the theoretical frameworks in HRI and provide detailed guidance to promote AI robot applications across different cultures. 相似文献

This study considers the dilemma faced by employees every time a colleague requests knowledge: should they share their knowledge? We use adaptive cost theory and self-efficacy theory to examine how individual characteristics (i.e., self-efficacy and trait competitiveness) and situational perceptions (i.e., ‘busyness’ and perceived competition) affect knowledge sharing behaviours. A study was conducted with 403 students who completed a problem-solving exercise and who were permitted (but not required) to respond to requests for knowledge from people who were doing the same activity. Our results suggest that people who perceive significant time pressure are less likely to share knowledge. Trait competitiveness predicted perceived competition. This and low task self-efficacy created a sense of time pressure, which in turn led to people feeling ‘too busy’ to share their knowledge when it was requested. Perceived competition was not directly related to knowledge sharing. Implications for research and practitioners are discussed. 相似文献

The mucopolysaccharidoses (MPSs) are a heterogeneous group of rare inherited disorders caused by deficiency of lysosomal enzyme necessary to break down mucopolysaccharides or glycosaminoglycans (GAGs). We had combined clinical findings and ophthalmological features. Biochemical test for urine glycosaminoglycans was done for confirmation of diagnosis in the patient. The case of Sanfillippo’s disease was characterized by delayed development, hyperactivity with aggressive behaviour. Coarse facial feature, hirsutism and sleep disorder. Urine GAG tests for MPS was positive in the case. Based on clinical findings and biochemical tests for MPS, this case was diagnosed as a type III mucopolysaccharidoses. Urinary GAG’s electrophoresis is an important screening test for MPS suspected cases. 相似文献

Polycyclic aromatic hydrocarbons (PAHs) are among the most prevalent environmental pollutants and result from the incomplete combustion of hydrocarbons (coal and gasoline, fossil fuel combustion, byproducts of industrial processing, natural emission, cigarette smoking, etc.). The first phase of xenobiotic biotransformation in the PAH metabolism includes activities of cytochrome P450 from the CYP1 family and microsomal epoxide hydrolase. The products of this biotransformation are reactive oxygen species that are transformed in the second phase through the formation of conjugates with glutathione, glucuronate or sulphates. PAH exposure may lead to PAH-DNA adduct formation or induce an inflammatory atherosclerotic plaque phenotype. Several genetic polymorphisms of genes encoded for enzymes involved in PAH biotransformation have been proven to lead to the development of diseases. Enzyme CYP P450 1A1, which is encoded by the CYP1A1 gene, is vital in the monooxygenation of lipofilic substrates, while GSTM1 and GSTT1 are the most abundant isophorms that conjugate and neutralize oxygen products. Some single nucleotide polymorphisms of the CYP1A1 gene as well as the deletion polymorphisms of GSTT1 and GSTM1 may alter the final specific cellular inflammatory respond. Occupational exposure or conditions from the living environment can contribute to the production of PAH metabolites with adverse effects on human health. The aim of this study was to obtain data on biotransformation and atherosclerosis, as well as data on the gene polymorphisms involved in biotransformation, in order to better study gene expression and further elucidate the interaction between genes and the environment. 相似文献

Among the various forms of academic misconduct, text recycling or ‘self-plagiarism’ holds a particularly contentious position as a new way to game the reward system of science. A recent case of alleged ‘self-plagiarism’ by the prominent Dutch economist Peter Nijkamp has attracted much public and regulatory attention in the Netherlands. During the Nijkamp controversy, it became evident that many questions around text recycling have only partly been answered and that much uncertainty still exists. While the conditions of fair text reuse have been specified more clearly in the wake of this case, the extent and causes of problematic text recycling remain unclear. In this study, we investigated the extent of problematic text recycling in order to obtain understanding of its occurrence in four research areas: biochemistry & molecular biology, economics, history and psychology. We also investigated some potential reasons and motives for authors to recycle their text, by testing current hypotheses in scholarly literature regarding the causes of text recycling. To this end, an analysis was performed on 922 journal articles, using the Turnitin plagiarism detection software, followed by close manual interpretation of the results. We observed considerable levels of problematic text recycling, particularly in economics and psychology, while it became clear that the extent of text recycling varies substantially between research fields. In addition, we found evidence that more productive authors are more likely to recycle their papers. In addition, the analysis provides insight into the influence of the number of authors and the existence of editorial policies on the occurrence of problematic text recycling. 相似文献
