Customer Reviews for Individual Product Feature-based Ranking

As the number of products being sold online increases, it is becoming increasingly difficult for customers to make purchasing decisions based on only pictures and short product descriptions. Thus, customer reviews, particularly the text describing the features, comparisons and experiences of using a particular product provide a rich source of information to compare products and make purchasing decisions. Especially, all kinds of reviews from various people have different degree of impact on a buyer, that is, we tend to believe our friends who always make right decisions than others. In this paper, we present an individual feature-based product ranking technique that mines thousands of customer reviews. By grouping users into unfamiliar users and familiar users according to the fact whether the client has almost always right ideas as far as one has concerned we attach different weights to them based on the friend ranking list. Friends on the top of the list are expected to be more reliable than the rest. After founding the client's friend set{F_j, S_k}, we extract crucial information from users' reviews. By realizing key words in a sentence, we classify comments into 4 representative sentences-Active Direct sentence(AD), Inactive Direct sentence(ID), Active Indirect sentence(AI), and Inactive Indirect sentence(II). Afterwards, we construct a weighted graph considering the product weight itself and the edge between every 2 relevant products, using ratios AD/ID and ID/II. The last step is that the client ranks search result with the average reliabilities of himself with respect to reviews of specific feature. Through calculation, we have a weighted score list, helping the client make purchase intentions.
Comparison of Internet and interview survey modes when estimating willingness to pay using choice experiments

Abstract With the increasing use of the Internet as a survey mode, questions of mode effects and how potential effects influence inferences arise. Using a choice experiment combined with mixed logit estimation, willingness-to-pays (WTPs) for attributes are compared between the Internet mode and the more traditional interview survey mode. The results suggest that there are differences in WTP between the two survey models for three of four attributes. Furthermore, WTPs obtained from the interview survey are larger than the WTPs obtained from the Internet survey, suggesting potential social desirability behaviour by the interview respondents. Internet surveys involving sensitive issues may be desirable because of potential social desirability behaviour.
Neutrophil secretory defect in the gray platelet syndrome: A new case

We report the case of a 60-year-old woman who was newly diagnosed for the gray platelet syndrome (GPS). This patient had long-term thrombocytopenia which had been initially misdiagnosed as idiopathic thrombocytopenic purpura (ITP). Blood smear displayed characteristic gray platelets, allowing the diagnosis to be made, which was confirmed by electron microscopy (EM). Polymorphonuclear neutrophils (PMN) appeared poorly granulated on the May–Grunwald–Giemsa-stained blood smear. Flow cytometry analysis of PMN demonstrated increased expression of CD35, CD11b and CD18 at resting PMN surface, without any changes after fMLP stimulation. Ultrastructural study retrieved a decreased number of myeloperoxidase (MPO)-negative secondary granules in PMN. Immunolabeling confirmed the presence of membrane proteins and the absence of soluble content in platelet and megakaryocyte (MK) α-granules, and the decrease of secondary granules and secretory vesicles in PMN. This new observation demonstrates that the impairment of the secretory compartment of PMN is definitely a hallmark of GPS, and that the detection of these subtle abnormalities should be searched with adequate and up-to-date technical approaches.
Integrin activation and structural rearrangement

Summary: Among adhesion receptor families, integrins are particularly important in biological processes that require rapid modulation of adhesion and de‐adhesion. Activation on a timescale of < 1 s of β2 integrins on leukocytes and β3 integrins on platelets enables deposition of these cells at sites of inflammation or vessel wall injury. Recent crystal, nuclear magnetic resonance (NMR), and electron microscope (EM) structures of integrins and their domains lead to a unifying mechanism of activation for both integrins that contain and those that lack an inserted (I) domain. The I domain adopts two alternative conformations, termed open and closed. In striking similarity to signaling G‐proteins, rearrangement of a Mg2+‐binding site is linked to large conformational movements in distant backbone regions. Mutations that stabilize a particular conformation show that the open conformation has high affinity for ligand, whereas the closed conformation has low affinity. Movement of the C‐terminal α‐helix 10 Å down the side of the domain in the open conformation is sufficient to increase affinity at the distal ligand‐binding site 9000‐fold. This C‐terminal “bell‐rope” provides a mechanism for linkage to conformational movements in other domains. Recent structures and functional studies reveal interactions between β‐propeller, I, and I‐like domains in the integrin headpiece, and a critical role for integrin epidermal growth factor (EGF) domains in the stalk region. The headpiece of the integrin faces down towards the membrane in the inactive conformation, and extends upward in a “switchblade”‐like opening upon activation. These long‐range structural rearrangements of the entire integrin molecule involving interdomain contacts appear closely linked to conformational changes within the I and I‐like domains, which result in increased affinity and competence for ligand binding.
Balancing empiricism and local cultural knowledge in the design of prevention research

Prevention research aims to address health and social problems via systematic strategies for affecting and documenting change. To produce meaningful and lasting results at the level of the community, prevention research frequently requires investigators to reevaluate the boundaries that have traditionally separated them from the subjects of their investigations. New tools and techniques are required to facilitate collaboration between researchers and communities while maintaining scientific rigor. This article describes the tribal participatory research approach, which was developed to facilitate culturally centered prevention research in American Indian and Alaska Native communities. This approach is discussed within the broader context of community-based participatory research, an increasingly prevalent paradigm in the prevention field. Strengths and limitations of the approach used in the study are presented.
Resources, capabilities, export performance and the moderating role of entrepreneurial orientation in the context of SMEs

Export activities of Small and Medium-sized Enterprises (SMEs) play a vital role in small economies with limited domestic markets. This paper investigates critical resources and capabilities of SMEs for export performance and their contingency upon entrepreneurial orientation. The proposed model builds on the theories of the resource-based view, the dynamic capability view and entrepreneurship to select relevant antecedents and argue their performance impact. The hypotheses were tested with cross-industry data collected from 102 Slovenian SMEs using structural equation modelling. Our results support that human resources, brand and entrepreneurial orientation positively affect SMEs’ export performance, while management experience, market and innovation capabilities only increase performance in the face of high entrepreneurial orientation. Further results and implications are discussed.
Intenational Currency Experience: New Lessons and Lessons Relearned

THE BROOKINGS PANEL on Economic Activity first met twenty-five years ago, at a moment of temporary reprieve but ominous portent for the international monetary system. The Bretton Woods system of pegged but adjustable dollar exchange rates had permitted the world economy more than two decades of robust growth and generally low inflation. But the structure was starting to unravel. The 1967 devaluation of sterling, the 1968 divorce of the market and official prices of gold, and the 1969 realignments of the French franc and German mark had papered over localized tensions in the Bretton Woods order. At the same time, those events vividly demonstrated that seemingly cherished official commitments could easily succumb to speculative pressures. By March 1973 the Bretton Woods system was history, and dollar exchange rates were floating. In 1970 a majority of academics and policymakers wanted greater exchange rate flexibility. But most, mindful of Ragnar Nurkse's critique of interwar currency practices, did not go so far as to advocatefloating dollar exchange rates. I Typical proposals favored less extreme departures from the existing arrangement: wider fluctuation margins, smaller and
What is the ‘high skills society’? Some reflections on current academic and policy debates in the UK

The UK government has committed itself to building a high skills future for the UK. However, despite widespread use of terms such as the ‘knowledge economy’, ‘the high skills society’ and ‘the learning society’, there remains much confusion as to the kind of economy or society different commentators are actually aiming at. The paper seeks to add clarity to current debates by mapping the various visions to emerge from three key groupings: (i) government and ‘social actors’, (ii) those writing from an educationalist background and (iii) those coming from a broadly industrial relations tradition. By highlighting the confusion, tensions and contradictions that exist, it soon becomes clear that high skills are far from being the consensual policy option they initially appear. It is only by opening up these issues that we can appreciate the different aims that exist at the centre of the UK skills debate and begin to confront the real political choices available.
Pulmonary rehabilitation and whole-body vibration in chronic obstructive pulmonary disease

The Whole-Body Vibration (WBV) has been described as an alternative therapeutic resource for patients with Chronic Obstructive Pulmonary Disease (COPD) with similarity to the Pulmonary Rehabilitation Program (PRP). The aim of the study was to compare PRP to WBV on functional capacity and quality of life in patients with COPD. Twenty individuals with COPD were assigned to PRP and WBV, who were evaluated regarding their lung function, functional capacity and quality of life through spirometry, 6-minute walk test (6MWT) and St. George Respiratory Questionnaire (SGRQ), respectively. The main results for the WBV group were, there were improvements in the walked distance on the 6MWT and in the symptoms and total domains of the SGRQ. For the PRP group, we observed improvement in the activity, impact and total domains of SGRQ. We could conclude that the WBV group increased the walked distance in regard to the PRP group and both programs improved the quality of life.
Diet of Risso's dolphin ( Grampus griseus ) in the western Mediterranean Sea

The diet of Risso’s dolphin in the Mediterranean is described based on 15 animals stranded between 40°25’N 00°32’W and 37°35’N 00°45’E from April 1987 to January 2003. The prey were mainly oceanic cephalopods. Pelagic octopods, especially A. argo, were the most abundant (mean = 41.28%; SD±34.32). Species belonging to the families Ommastrephidae, Histioteuthidae and Onychoteuthidae were also frequent components of its diet. The bathymetric distribution of cephalopods shows that Risso’s dolphin preferentially feeds on the middle slope (600 to 800 m depth) in the Mediterranean.
Determinants of profitability in the EU-15 area

Using data on private firms in the EU-15 area over the period 2004–2011, we investigate the determinants of firm profitability. We extend existing models by considering possible nonlinear effects of typical micro-level determinants as well as the effect of additional micro-level and macro-level variables. Our findings – obtained using a plethora of econometric static and dynamic models – show that nonlinearities help explain the existence of conflicting theories of determinants of profitability (omitting second-order effects may result in inconsistent estimates) and shed light on the role of the firm’s opportunity cost of capital, the majority shareholder commitment level and variables which reflect the economic cycle in explaining firm profitability.
The Price-to-income Ratio and the Quality of Life

This paper argues that a cross-city comparison of price-to-income ratios can exaggerate the bubble in high QOL (quality of life) cities. The theory is based on Roback (1982). In high QOL cities people are willing to pay high housing rents and get paid lower wages. This would lead to higher price-to-income ratios even if there were no bubble or irrational expectation on future price growth. We test the theory using data. The challenge is that expected price growth rate may be correlated with QOL across
Globalisation Challenges and Competitiveness: The Role of the State and Private Sector in Malaysia

This paper will examine the challenges of the globalisation process on the Malaysian economy and the role of the state and the private sector and their state of competitiveness in meeting the challenges. Issues relating to the enhancement of technological capability, the role of education, training and R&D will be examined in greater depth with respect to the country's quest for industrial nation status by the year 2020.
Some Problems of Money Demand

THE CURRENT ECONOMIC upturn has been characterized by unusually low rates of money growth relative to the increase in nominal gross national product. Even more surprising, the unusual rise in velocity has occurred while short-term interest rates have remained largely unchanged or even fallen slightly (see table 1). This development contradicts much of the supposed knowledge about the public's demand for money and its determinants. The present shortfall of money demand from its expected value has important consequences for current monetary policy and the increased uncertainty about the demand for money in the future has implications for the conduct of policy generally. ' The first section of this paper describes the magnitude of the problem. The second section briefly reviews a simple version of the theory of money demand in order to provide a framework for examining causes of the problem. It lists some potential inadequacies of the theory and data and then focuses on current developments that are not embodied in the simple theory and that might help explain recent money demand. The next section presents some empirical tests, and the final section offers conclusions.
Two Tails of Housing-led Urban Regeneration Policy Network: The UK and South Korea

As the previous service delivery mechanism initiated by government is not desirable anymore, institutional agency on behalf of government is necessary to intermediate public and private interests through policy network. The focus of this study is to identify the role of different intermediate agencies of Cardiff and Seoul within policy network towards sustainable community building through housing-led urban regeneration. It was identified that the policy network of Cardiff was a horizontal network administration organization-type issue network, which favoured inclusiveness, sequential legitimacy and stability with a private-like, bottom-up relational role and a wide coverage of functional role. The policy network of Seoul was a hierarchical, lead organization-type policy community, which favoured efficiency, internal legitimacy and stability with a public-like, top-down relational role and a narrow range of functional role. Finally, it was suggested that housing-led regeneration should be networked effectively through the better role of intermediate agency.
Turnover Intentions and Work Motivations of Millennial Employees in Federal Service

In the face of looming retirements in the federal service, retaining and motivating the next generation of workers has emerged as a critical concern for human resource professionals in federal agencies. While a growing body of work provides advice and strategies on making government work more inviting for the members of the Millennial generation, those born after 1982, not much is known about the turnover intentions of those already in public service. Do Millennial workers in the federal agencies resemble older workers in terms of their work motivations and turnover intentions? This study compares Millennial and older generation workers in U.S. federal agencies, in terms of their turnover intentions and work motivations. The analyses show that they are more likely than their older counterparts to report an intention to leave their jobs, and most work attributes do not matter more for Millennial workers’ decisions to leave.
Website quality and customer's behavioural intention: an exploratory study of the role of information asymmetry

Abstract The purpose of this study is to explore the relationship between website quality and customer's behavioural intention across search, experience and credence goods/services. After conducting an empirical study in Taiwan, website quality consists of five important factors: connectivity, information quality, interactivity, playfulness, and learning. The results of this study suggest that the factors of connectivity, interactivity, playfulness, and learning have positive impacts on customer's behavioural intention for search goods/services. Connectivity, information quality, and interactivity are helpful to strengthen customer's behavioural intention for experience goods/services. However, only information quality and interactivity are significant to improve customer's behavioural intention in credence goods/services.
Auditing and reporting in Europe: an analysis using country‐level data

Purpose - This paper aims to investigate the determinants of the strength of auditing and reporting standards (SARS) in 41 European countries. It posits that there are a number of country-level determinants for the SARS and these determinants are grouped into four main categories: legal framework, corporate governance, market and higher education. This study aims to expand the domain of auditing and reporting by using country-level data than is usually found in the auditing literature. Design/methodology/approach - Data were accessed from the World Economic Forum (WEF) Report (2009), World Bank Reports on Observation of Standards and Codes (ROSC) and the International Federation of Accountants (IFAC). The ROSC was used to synthesise the status of auditing in the 41 countries, whereas the IFAC report was used to determine the adoption of international standards on auditing. Data on SARS and its determinants were gathered from the WEF Report to empirically examine the validity of the hypotheses. The ranks of SARS were regressed on the ranks of its determinants. Findings - This paper provides additional empirical evidence on SARS in Europe. It suggests that, in addition to extant literature, judicial independence and efficiency of the legal framework, ethical behaviour of firms, efficacy of corporate boards, strengths of the stock market and extent of staff training in the European countries impact on its SARS. Research limitations/implications - Because the ROSC are not available for all the European countries, this study could not comment on the status of auditing for all the 41 countries. Second, had the countries been grouped into developed, emerging and developing, the determinants of SARS could be different. Practical implications - This paper emphasises the importance of the efficiency of legal framework, corporate governance and the training of staff to maintain a reasonable SARS. Originality/value - This study fills the research gap regarding the absence of an empirical cross-country study on the determinants of the SARS in Europe
Isolation and characterization of c-myc, a cellular homolog of the oncogene (v-myc) of avian myelocytomatosis virus strain 29

The chicken genome contains nucleotide sequences homologous to transforming genes (oncogenes) of a number of avian retroviruses. We have isolated chicken DNA (c-myc) that is homologous to the oncogene (v-myc) of the avian myelocytomatosis virus MC29 and have compared the structures of the cellular and viral genes. Results from restriction endonuclease mapping of c-myc and from analysis of heteroduplexes between the DNAs of the cellular and viral genes show that c-myc is homologous to 1,500 nucleotides in v-myc DNA. This homologous region is interrupted in c-myc by an intron-like sequence of 1,100 nucleotides which is absent from v-myc. Nuclear RNA from normal chicken cells contains at least five species of transcripts from c-myc ranging from 2.5 to 6.5 kilobases in length. By contrast, cytoplasm contains only the 2.5-kilobase c-myc RNA. These features of the c-myc gene and its nuclear transcripts are characteristic of normal cellular genes and suggest that the myc gene is of cellular rather than viral origin. The exons in c-myc may define two functional domains in the gene and may therefore facilitate the dissection of the different oncogenic potentials of the MC29 virus.
Photoageing: mechanism, prevention and therapy

Photoageing is the superposition of chronic ultraviolet (UV)‐induced damage on intrinsic ageing and accounts for most age‐associated changes in skin appearance. It is triggered by receptor‐initiated signalling, mitochondrial damage, protein oxidation and telomere‐based DNA damage responses. Photodamaged skin displays variable epidermal thickness, dermal elastosis, decreased/fragmented collagen, increased matrix‐degrading metalloproteinases, inflammatory infiltrates and vessel ectasia. The development of cosmetically pleasing sunscreens that protect against both UVA and UVB irradiation as well as products such as tretinoin that antagonize the UV signalling pathways leading to photoageing are major steps forward in preventing and reversing photoageing. Improved understanding of the skin’s innate UV protective mechanisms has also given rise to several novel treatment concepts that promise to revolutionize this field within the coming decade. Such advances should not only allow for the improved appearance of skin in middle age and beyond, but also greatly reduce the accompanying burden of skin cancer.
Plasticity of the Right-Lateralized Cognitive Reserve Network in Ageing

Cognitive reserve (CR) is the phenomenon where older adults with more cognitively stimulating environments show less age-related cognitive decline. The right-lateralized fronto-parietal network has been proposed to significantly contribute to CR and visual attention in ageing. In this study we tested whether plasticity of this network may be harnessed in ageing.We assessed CR and parameters of visual attention capacity in older adults. Transcranial direct current stimulation (tDCS) was employed to increase right fronto-parietal activity during a lateralized whole-report task. At baseline, older adults with greater CR showed a stronger hemifield asymmetry in processing speed towards the left visual-field, indicative of stronger involvement of the right hemisphere in these individuals. Correspondingly, processing speed improved during right prefrontal tDCS. Older adults with lower levels of CR showed tDCS-related improvements in processing speed in the left but not right hemifield: thus tDCS temporarily altered their processing speed asymmetry to resemble that of their high reserve peers.The finding that stronger right hemisphere involvement is related to CR supports Robertson's theory. Furthermore, preserved plasticity within the right prefrontal cortex in older adults suggests this is a viable target area to improve visual processing speed, a hallmark of age-related decline.
