A fair mechanism of virtual radio resource management in multi-RAT wireless het-nets

Wireless network virtualisation is a promising technology for future mobile communications, providing efficient and convergent mechanisms of resource management for emerging heterogeneous wireless networks. This paper proposes a model of virtual radio resource management in wireless heterogeneous networks, which can address the data rate requirements of different service classes provided by a virtual network operator, while implementing an efficient algorithm for fairness to satisfy all users based on their service priorities. The model is further extended to deal with the high traffic load, resulting from situations when there is not enough capacity to serve all users. A practical scenario is implemented to evaluate model performance, and results show that the maximum utilisation of the available capacity is achieved independent of the traffic load, while service level agreements are satisfied. Moreover, when possible, the proposed algorithm can keep a level of fairness among users from different service classes according to the predefined serving weights. Numerical results confirm that almost always 100% of the aggregated capacity is used.
Brookite: Nothing New under the Sun?

Advances in the synthesis of pure brookite and brookite-based TiO2 materials have opened the way to fundamental and applicative studies of the once least known TiO2 polymorph. Brookite is now recognized as an active phase, in some cases showing enhanced performance with respect to anatase, rutile or their mixture. The peculiar structure of brookite determines its distinct electronic properties, such as band gap, charge–carrier lifetime and mobility, trapping sites, surface energetics, surface atom arrangements and adsorption sites. Understanding the relationship between these properties and the photocatalytic performances of brookite compared to other TiO2 polymorphs is still a formidable challenge, because of the interplay of many factors contributing to the observed efficiency of a given photocatalyst. Here, the most recent advances in brookite TiO2 material synthesis and applications are summarized, focusing on structure/activity relation studies of phase and morphology-controlled materials. Many questions remain unanswered regarding brookite, but one answer is clear: Is it still worth studying such a hard-to-synthesize, elusive TiO2 polymorph? Yes.
Study of the Usability of the Private Social Network SocialNet using Heuristic Evaluation

The purpose of this paper is the usability evaluation of the SocialNet, a private social network for monitoring daily progress of patients by their relatives. This work presents the first phase where it was used the double heuristic evaluation as a method of evaluating usability. It has proven to be a suitable method for finding usability problems associated with this type of social network where information privacy plays an important role. The evaluation has provided data about the origin of the usability problems of SocialNet, especially related to consistency, design and privacy. Findings have helped to redesign some aspects of SocialNet and to provide an effective, efficient interaction and satisfactory experience to the users. The use of heuristic evaluation will be complemented with a user test to be carried out in a second phase of the usability study, which is not addressed in this paper.
Transfection of multiple pulmonary cell types following intravenous injection of PEI‐DNA in normal and CFTR mutant mice

The polycationic vector polyethylenimine (PEI) has been shown to be a powerful agent for transfecting the mouse lung after injection of plasmid‐based polyplexes through the tail vein. These findings raise therapeutic prospects for a number of lung conditions. For such potentials to be realised, the precise identity of the transfected cells remains to be determined; however, so far, no ultrastructural analysis has been performed on PEI‐transfected lungs. The definition of which pulmonary cells are transfected is particularly critical for certain pulmonary diseases which might require transfection of defined cell types such as epithelial cells for cystic fibrosis (CF).
Concerns vital for mobile CRM in banking: a qualitative study

For the past few decades the technology acceptance model (TAM) has dominated the research on factors affecting the acceptance of new technology. The two fundamental constructs, ease of use and usefulness, in the model may not, however, fully explain the consumers’ behaviour in an emerging environment. This research paper primarily aims to examine a framework for mobile-customer relationship adoption process. In this paper TAM has been extended to analyse the factors for successful adoption of mobile application used for CRM purposes. The key elements that emerged are perceived value, compatibility, and security and privacy concerns. Interestingly profound combined effect of factors like risk, trust, security and privacy was found in the case of mobile CRM.
Pharmacogenetics and oncology treatment for breast cancer

Breast cancer is the second most common cause of cancer-related death in women in the US and the UK, accounting for 15 – 17% of all female cancer deaths. Current treatment strategies include hormone therapy, such as anti-estrogens (tamoxifen) and aromatase inhibitors (exemastane, anastrozole, letrozole), as well as cytotoxics, such as the taxanes (paclitaxel, docetaxel). With multiple therapy choices, a method to prospectively screen patients prior to therapy selection is now needed. Pharmacogenetics seeks to develop screening mechanisms to optimise drug therapy. DNA variations in metabolism, transport and drug target genes may contribute to chemotherapy efficacy and toxicities. The status of the identification of genetic markers for breast cancer therapy selection is highlighted in this review.
A community‐based study of the epidemiology of Helicobacter pylori infection and associated asymptomatic gastroduodenal pathology

Objectives To document the epidemiology of Helicobacter pylori infection in a normal population, to assess asymptomatic H. pylori positive individuals for the presence of gastroduodenal disease, and to compare the macroscopic and microscopic findings at endoscopy in this group with those of patients presenting with dyspepsia. Design/Methods Serum was collected from blood donors and assessed for the presence of anti-H. pylori IgG antibodies. A randomly selected group of asymptomatic blood donors and dyspeptic patients underwent endoscopy. Results The seroprevalence of H. pylori in 1000 subjects was 43.0%. The prevalence of infection increased from 29% in 18–30 year olds to 62% in 46–60 year olds (P < 0.01). The infection was more prevalent in individuals from social classes IV and V (50.0%) than social classes I and II (36.9%) (P < 0.01). There was no difference between the H. pylori positive asymptomatic individuals (n = 37) and matched dyspeptic patients (n = 29) at endoscopy with regard to duodenal ulcer (13.5% vs. 17.2%) or gastroduodenal erosions (24.3% vs. 20.7%) while 5.4% of the former had gastro-oesophageal reflux compared to 27.6% of the latter. Overall, 56.8% of the H. pylori positive asymptomatic group had a normal macroscopic endoscopy compared with 31 % of the dyspeptic group. Histology of the gastric mucosa did not reveal any significant differences between the two groups. In H. pylori negative asymptomatic individuals (n = 13) 92.3% had a normal endoscopy (7.7% had grade I gastro-oesophageal reflux) compared with 61.5% of a matched dyspeptic group (n = 13). Conclusion H. pylori infection, symptomatic and asymptomatic, is associated with significant pathology, and screening for the infection may be indicated for the prevention of gastroduodenal diseases.
Treating mastitis in the cow – a tradition or an archaism

Intramammary infection of the dairy cow is much less common than 40 years ago due to the impact of a control programme. This has changed the aetiology of the infection. The problem remains one of the costliest affecting farm animal health, estimated at £300 million annually in the UK. The successful control relies much on antibiotic treatments. The use of antibiotics in food animals is under challenge, particularly use of broad spectrum, multicomponent products and use of prophylactic treatment. Recent research has confirmed that antibiotic treatment is practical and cost-effective. Moreover, it remains essential for animal welfare.
Cognitive Dissonance and Buyers’ Coping Mechanisms: A Comparative Study of US and Indian Consumers

This study empirically examined difference in the cognitive dissonance resolution behavior of US and Indian consumers. The data was collected through an online survey through the use of convenience and snowball sampling techniques. The use of ANOVA provided the results that indicate that Indian consumers are more cautious and risk-averse in their approach to purchases than US consumers. US consumers demonstrate a higher level of individualistic thinking and are more confident of their choices while Indian consumers have more collectivistic thinking and want peer approval of their choices. US consumers came out to be more aggressive in their post purchase dissonance reducing behavior while Indian consumers appeared to be more willing to compromise with a bad purchase.
Learning the Web

Abstract This article focuses on how Internet users change their behaviors and responses to marketing with increasing experience. Data from three empirical studies show several effects of increasing Internet user experience. Experienced users have shorter and more focused Web sessions, and they tend to reduce their visits to a smaller number of well-known Web sites. Furthermore, as experience increases, Internet users screen out advertising and they are less inclined to click on banner ads and less likely to be affected by ad exposures. The article tries to explain these effects, thus advancing theory on Internet marketing. Important implications for Web marketing practice are provided.
Elements of Successful Graduate Real Estate Programs: Perceptions of the Stakeholders

Graduate programs with a concentration in real estate continue to search for the best ways to educate students. In an effort to uncover the views and opinions of various stakeholders in real estate education on the key elements of a successful program, this study analyzes the data collected from a survey of almost 1,000 individuals. The results show that there are similarities, but also many differences between the opinions of faculty, administrators, students, alumni, and board members. These findings may help faculty and administrators revise existing programs or design/develop new ones. They may also help prospective students evaluate the different programs. Finally, the results provide some insight into the often-cited disconnect between "town and gown," and opens the dialogue for all involved to work together to improve the programs.
Pretreatment ipsilateral regional cortical blood flow influences vessel recanalization in intra-arterial thrombolysis for MCA occlusion.

BACKGROUND AND PURPOSE The aim of acute stroke interventions is to achieve recanalization of the target occluded artery. We sought to determine whether pretreatment cortical cerebral blood flow (CBF) was associated with vessel recanalization in patients undergoing intra-arterial therapy. METHODS This is a retrospective analysis of patients who underwent a quantitative xenon CT blood flow study and were noted to have a documented M1 middle cerebral artery (MCA) or carotid terminus occlusion less than 6 hours from symptom onset between January 1997 and April 2001. Twenty-three patients who underwent intra-arterial thrombolysis were included in the analysis. Univariate and multivariate analyses were performed to determine whether pretherapy CBF was correlated to the likelihood of recanalization. RESULTS A total of 23 patients were studied in this analysis with a median age of 69 (range 32-81) and median National Institutes of Health Stroke Score of 19 (range, 8-22). Twelve patients (52%) underwent combined intravenous/intra-arterial therapy, and 11 patients (48%) were treated with intra-arterial thrombolytics alone. Successful vessel recanalization (Thrombolysis in Myocardial Infarction classification 2 or 3 flow) occurred in 13 patients (57%). The only variable associated with recanalization in multivariate modeling was mean ipsilateral MCA CBF (odds ratio, 1.25; 95% confidence interval, 1.01-1.54; P = .035). A receiver operating characteristic curve was generated, and a mean ipsilateral MCA CBF threshold of 18 mL/100 g/min was found to be the threshold for successful recanalization. CONCLUSIONS Our study suggests that patients with higher mean ipsilateral MCA CBF are more likely to recanalize. The threshold for successful revascularization may be 18 mL/100 g/min. Further study is required to determine whether pretreatment CBF is related to recanalization success.
Using visual exploratory data analysis to find bias in option pricing models

Options are amongst the most heavily transacted financial instruments in the world. This paper examines how the methods of visual exploratory tools, espoused by Cleveland (1993) can be used to analyze the residuals from conventional option pricing models (Black and Scholes, 1972; Black, 1976). Until recently, these models were believed to be unbiased (Rubinstein, 1985; Lajbcygier, 1999). With the aid of visual exploratory tools we see that options on the All Ordinaries share price index trading on the Sydney Futures exchange have persistent, systematic and significant bias. This is the first time that various statistically oriented visual exploratory tools have been used to analyze option residuals. We find that the analysis motivates the use of alternative option pricing methods.
The Conceptualization of Perceived Insufficient Milk Among Mexican Mothers

This study sought to provide a comprehensive picture of maternal conceptualization of Perceived Insufficient Milk (PIM) using qualitative methods (semistructured interviews, free lists, and rankings) in Mexico. Two hundred and seven first-time mothers of infants younger than 6 months and mothers-to-be who were (or intended to be) breastfeeding were interviewed in waiting areas at a hospital and a health clinic in Mexico City, Mexico, from September 2000 to January 2001. Pattern searching and triangulation of the 3 qualitative methods indicated that women viewed crying as the chief symptom of PIM. Maternal diet and liquid intake were cited as both the most salient causes and treatments for PIM. The main coping strategy in the event of PIM was formula feeding. These findings highlight the need for addressing maternal concerns in relation to PIM, especially regarding the role of crying as the initiator of the PIM cycle.
gWord: A Tool for Genome-Wide Word Search and Count

Word search and count in whole genome DNA sequence is very important for re-sequencing an organism's genome DNA using the microarray based technology and studying the functional element's function based on genome- wide approach. A stand-alone program named gWord (abbr. of genome Word), which applies a fast algorithm to rapidly map the n-mer word into an index in memory, is developed for the task that can fulfill two main functions: counting all possible n-mer short DNA sequences in genome and acquiring the locations of one motif or those words presented only once in genome DNA. In addition, the search hits of any word will be annotated with gene information. Two examples on human genome are given to demonstrate the application of gWord in genomics research.
Do the Governance, Strategic and Organisational Practices Differ in Indian Family and Professionally Managed Firms?

The professional firms suffer from exogenous problems whereas the private family firms suffer from endogenous problems. This latter category is more common in the family firms of emerging markets. Based on a sample of 157 firms we examine the key characteristic differences in the managerial practices of family firms and professional firms and relate them to the possible agency problems. We present the typology of the firms based on ownership and control and further divide the issues into strategy, organisation and governance issues. The family firms themselves definitionally vary depending upon the ownership and control-based classification. We classify all firms into four categories, but we compare only professional firms on one hand and all hues of family firms as one block on the other owning to a relatively smaller sample size and lack of clear distinctions made by the respondents. However, the conclusions distinguish only on a few dimensions. But owing to institutional and economic context both family and professional firms look alike in more respects than they look different. This highlights the major impact of institutional influence on the behaviours of the firms. The analysis indicates that family firms suffer from the size, age and transparency disadvantages as compared to professional firms, but the strategic, organisational and governance practices do not differ very widely from each other.
The Effects on the Relationship Learning from Relationship Enhancement Activities

Abstract This study utilized recursive systems to assess the causal relationship framework of the relationship enhancement activities, relationship commitment, and relationship learning. A total of 1,067 questionnaires were distributed to members in the Association of the Computer Science and Information Management (CSIM) in this study. The results demonstrated that regular associate activities were not positively correlated with affective commitment, but it directly affected relationship memory. Finally, we also discovered that marketing activities would enhance members' commitment and increase members' willingness to learning.
Relational Archetypes, Organizational Learning, and Value Creation: Extending the Human Resource Architecture

Theories of knowledge-based competition emphasize the firm's ability both to explore and to exploit knowledge as the source of value creation. We attempt to bring human resource management directly into this forum by introducing a framework of relational archetypes—entrepreneurial and cooperative—that are derived from unique configurations of three dimensions (structural, affective, and cognitive) of social relations within and across firm boundaries. We identify how human resource configurations can be linked to the strategic management of these relational archetypes.
Combining Genetics and Cell Biology to Crack the Code of Plant Cell Calcium Signaling

Plant hormones, light receptors, pathogens, and abiotic signals trigger elevations in the cytosolic calcium concentration, which mediate physiological and developmental responses. Recent studies are reviewed here that reveal how specific genetic mutations impair or modify stimulus-induced calcium elevations in plant cells. These studies provide genetic evidence for the importance of calcium as a second messenger in plant signal transduction. A fundamental question arises: How can different stimuli use the same second messenger, calcium, to mediate different responses? Recent research and models are reviewed that suggest that several important mechanisms contribute to specificity in calcium signaling in plant cells. These mechanisms include (i) activation of different calcium channels in the plasma membrane and organellar membranes, (ii) stimulus-specific calcium oscillation parameters, (iii) cell type-specific responses, and (iv) intracellular localization of calcium gradients and calcium elevations in plant cells. Plant hormones and light signals enable plants to respond to changes in their environment. These stimuli are perceived by receptors that transmit responses to the inside of cells by inducing changes in cytoplasmic concentrations of chemical messengers, such as calcium. Many plant hormone and light signals cause elevations in the cytoplasmic calcium concentration. Recent studies are reviewed here that reveal how genetic mutations disrupt stimulus-induced calcium elevations in plant cells. These studies provide genetic evidence for the importance of calcium as a second messenger in plant signal transduction. A classical question has remained unanswered until recently, namely, how can different stimuli use the same second messenger, calcium, to mediate different responses in plants? Recent research and models are reviewed here that show several important mechanisms contributing to specificity in calcium signaling in plant cells. These mechanisms include (i) the activation of different calcium channels in the plasma membrane and organellar membranes of plant cells; (ii) the specific frequencies needed by calcium oscillations to mediate specific responses; (iii) the differential responses of different cell types to the same stimulus; and (iv) within each cell, the importance of intracellular localization of calcium gradients and calcium elevations to elicit the response. These advances show that plant cells contain a sophisticated apparatus that allows them to respond to many different environmental conditions through the second messenger, calcium.
Development and validation of clinical prediction models for mortality, functional outcome and cognitive impairment after stroke: a study protocol

Introduction Stroke is a leading cause of adult disability and death worldwide. The neurological impairments associated with stroke prevent patients from performing basic daily activities and have enormous impact on families and caregivers. Practical and accurate tools to assist in predicting outcome after stroke at patient level can provide significant aid for patient management. Furthermore, prediction models of this kind can be useful for clinical research, health economics, policymaking and clinical decision support. Methods 2869 patients with first-ever stroke from South London Stroke Register (SLSR) (1995–2004) will be included in the development cohort. We will use information captured after baseline to construct multilevel models and a Cox proportional hazard model to predict cognitive impairment, functional outcome and mortality up to 5 years after stroke. Repeated random subsampling validation (Monte Carlo cross-validation) will be evaluated in model development. Data from participants recruited to the stroke register (2005–2014) will be used for temporal validation of the models. Data from participants recruited to the Dijon Stroke Register (1985–2015) will be used for external validation. Discrimination, calibration and clinical utility of the models will be presented. Ethics Patients, or for patients who cannot consent their relatives, gave written informed consent to participate in stroke-related studies within the SLSR. The SLSR design was approved by the ethics committees of Guy’s and St Thomas’ NHS Foundation Trust, Kings College Hospital, Queens Square and Westminster Hospitals (London). The Dijon Stroke Registry was approved by the Comité National des Registres and the InVS and has authorisation of the Commission Nationale de l’Informatique et des Libertés.
