Linear dynamics of the Lamb-Chaplygin dipole in the two-dimensional limit

The dynamics of the Lamb-Chaplygin dipole in the large-wavelength limit is investigated by means of linear analysis. Taking the three-dimensional spectrum of the Lamb-Chaplygin dipole calculated by Billant [“Three-dimensional stability of a vortex pair,” Phys. Fluids11, 2069 (1999)] as a reference, we first show that additional families of unstable modes are present in the spectrum. Among them, a family of symmetric modes and one of antisymmetric modes, both present in the large-wavelength limit, are the main topic of this investigation. The most unstable modes in these two families being purely two-dimensional, the two-dimensional dynamics is more particularly investigated. Our calculations show that the amplification rate of the antisymmetric instability is significantly larger than that of the symmetric instability. Also, while the two-dimensional symmetric mode is stationary and induces a shift of the dipole toward the upstream or downstream direction relatively to the dipole self-propagation velocity vector, the antisymmetric mode is unsteady and displaces the dipole into wavy oscillations about its initial straight trajectory. The leading physical mechanism of these two-dimensional instabilities is the vortex shedding that occurs downstream of the dipole. This shedding is the reaction of the external flow to the dipole motion and basically enables the conservation of the flow impulse. The destabilizing action of the wake is amplified as the displaced dipole generates more shedding. The dipole motion and the wake thus reinforce each other, leading to the instability. The strain mutually exerted by the vortices of the dipole, known as an essential mechanism of three-dimensional vortex pair instabilities, is also shown to participate to this destabilization.
Mediating Role of Customer Satisfaction in the Mid-Market Hotels: An Empirical Analysis

Objectives: The present study attempts to investigate the impact of quality-value proposition on loyalty outcomes (i.e. exclusivity, strength of preference, share of hospitality and willingness to recommend) mediated by customer satisfaction in mid-market hotel sector. Statistical Analysis: The survey instrument was first developed and pre-tested. The results of the pre-test were used to refine the instrument to improve its clarity and depth. A survey was conducted among customers of 24 mid-market hotels of Jharkhand, India. The perceptions of the respondents were measured using a Likert scale of 5 points. Data obtained from 372 respondents were analysed using Structural Equation Modelling (SEM) technique. Findings: The results of the study reveal that the impact of perceived value is more on customer satisfaction and customer loyalty outcomes than service quality in mid-market space, hence contradicting in toto the postulation prevalent in luxury hotel segment. In addition, the customer satisfaction has a positive significant effect on loyalty outcomes viz. exclusivity, customers’ strength of preference and customers’ willingness to recommend except share of hospitality in the mid-market hotel sector of Jharkhand. Moreover, customer satisfaction plays a strong and positive mediation role in the relationship between perceived value and customers’ strength of preference. It also mediates the relationship between service quality and exclusivity, service quality and willingness to recommend and as well as service quality and strength of preference in mid-market hotel sector. The outcomes of the study are significant, as it questions the presuppositions and enlightens new insights in the mid-market hotel sector. Application: Apart from emphasising on the service quality, the hospitality practitioners should pay further attention on creating and delivering more value to the customers to achieve greater level of customer satisfaction. This may lead to enhanced customer loyalty in the mid-market hotel sector. The business firms or entrepreneurs who seek to venture into mid-market hotel sector must design their marketing mix to deliver better value to the customers.
Australian nurses' and midwives' knowledge of computers and their attitudes to using them in their practice.

BACKGROUND The introduction of a new information retrieval system for the use of health service staff at a large tertiary referral hospital provided an excellent opportunity for nurses to make greater use of evidence to inform their practice. However, the extent to which nurses were able to access the resource was unknown. AIM The aim of the study was to obtain this information and to test nurses' knowledge of computers and their attitudes to using them in their practice. METHODS During October 2001 a computer use questionnaire was attached to the pay advice slips of all nursing staff at the Royal Brisbane and Royal Women's Hospital (n = 1708). Staff were asked to return their completed questionnaire in a preaddressed return envelope. To encourage this, a prize (a Gold Class cinema pass for two) was offered. RESULTS Of the 1708 questionnaires distributed, 590 were returned, giving a 34.5% response rate. Computer use was influenced by education, nursing seniority, age, and length of time in the service and, to a lesser extent, gender. CONCLUSIONS Information from the study has assisted planners and educators to identify clusters of nurses to target for interventions in this area. Results will also be used to assess the success of any interventions.
Impact of Stochastic Mismatch on Measured SRAM Performance of FinFETs with Resist/Spacer-Defined Fins: Role of Line-Edge-Roughness

Spacer-defined fin-patterning results in double/quadruple fin density and hence is attractive for high performance 32-nm CMOS applications. For the first time 55-nm gate-length FinFET SRAMs with resist- and spacer-defined fins are electrically compared. Due to short-range process variations, SRAM bit-cells with spacer-defined fins show approximately 2.5 times higher variability in static-noise-margin than resist-defined fins at VDD=1.2V. These SRAM test-cells achieve 130-nm planar-bulk comparable intra-bit-cell stochastic-mismatch and static noise margins
The Study of the Residents′ Willingness to Pay for Improving Air Quality in Qingdao

With the help of the questionnaire survey,we obtain the related data about the Qingdao city residents′ air quality awareness and willingness to pay for the improvement of air quality.By introducing demographic,economic and air quality awareness variables,we use Logit model to analysis the factor that influence whether to pay,then utilize Tobit model and adopt symmetrically trimmed least square method that is more suitable for error item which is non-normally distributed and heteroscedasticity.The result of study show that the proportion of Qingdao City residents who are willing to pay is 86.71 percent,air quality awareness has the greatest impact on whether to pay while income level influence the pay amount the most.We also estimate that the annual total pay amount of the residents is 1.184 billion Yuan currently for improving the air quality and the amount will continue to rise as income levels and air quality awareness move up.We suggest that it′s more feasible to charge to residents to improve the air quality if the government increase publicity of the knowledge of air quality,raise residents′ attention on air quality,guide residents to form a good value judgment,raise residents′ satisfaction on air quality and enhance the transparency of the use of funds.
AN ASSESSMENT OF THE CONTRIBUTION OF MICROFINANCE LOANS TO THE GROWTH OF MICRO, SMALL AND MEDIUM ENTERPRISES (MSMES) IN BULAWAYO (2009-2013)

Deindustrialization in Bulawayo has led to the burgeoning of the informal sector evidenced by the emergence of many MSMEs.The research sought to assess the contribution of Microfinance loans to growth of MSMEs in Bulawayo (2009-2013). The research adopted a descriptive survey design. Primary data was collected through questionnaires and interviews from MSMEs. The research finds strong evidence that the contribution of microfinance loans to growth of MSMEs is not significant. Microfinance Institutions activities in the establishment of new MSMEs is nonexistent with most MSMEs source of funding coming from savings, friends and relatives. The study recommends that Microfinance Institutions engage in extensive marketing research and outreach programmes to MSMEs . This will help them to identify specific needs and design products that are suitable and tailored made for MSMEs.
Testing the Pecking Order, Method-of-Payment, Financial Slack, and Misvaluation Hypotheses for Tender Offers: Evidence from Japan

In this paper, we investigated the affect of tender offer transactions in Japan from four perspectives. The first one is in regards to the Pecking Order Theory, and the second one concerns the Method-of-Payment Hypothesis. Both of these first two perspectives are related to manager payment method decisions, such as cash versus stocks. The third perspective is taken from the Financial Slack Hypothesis, which is very similar to the Free Cash Flow Hypothesis, and the last perspective takes into account the Misvaluation Hypothesis. These latter two perspectives are similarly related to the subsequent responses from investors that follow the announcements of tender offers. We found strong evidence supporting the Pecking Order Theory, because managers are deeply motivated to select cash payments when they have an extensive amount of financial slack, free cash flow, representative of cash or cash equivalent. Unfortunately, on the other hand, we could not find any empirical data to fully support the Method-of-Payment hypothesis which was originally introduced and supported empirically in the U.S. Evidence from our research for the Financial Slack or Free Cash Flow and Misvaluation hypotheses proved that investor reactions in Japan are similar to those in the U.S. A Japanese market with an increase in tender offer transactions contributes to the wealth of both acquiring and target firms, despite the stock market responding negatively to investments from acquiring firms with an extensive amount of financial slack or free cash flow. Furthermore, our B/P ratio conclusions reaffirm the propositions of Shleifer and Vishny (2003), while the V/P ratios support Dong, et al. (2006) who used the Residual Income Model.
Technological Networking and Innovation Implementation

This paper presents a theory of innovation which presumes that new technologies emerge from a firm's accumulated stock of skills. Among these we distinguish technological and networking skills. We examine two aspects of innovating firms: their inclination to adopt a technological innovation, and their propensity to implement innovation alone or with other firms. Historical conditions pertaining to organizational skills are examined to account for these aspects. Among the most important are a firm's cumulative stream of technological projects that have some affinity to the new technology. A second important antecedent can be inferred from a firm's history of technological networking. Networking includes licensing, joint ventures and long-term contracts and can be formed for technological reasons, or for reasons having to do with the delivery of products and services. Networking is deemed important for facilitating access to strands of technology that are alien to a firm. Linkages are also conducive for contemplating strategic partnerships through which a firm can share the risks of innovation with others and which make such partnerships comparatively easy. The study examined a sample of United States commercial banks during the period 1977–1987, some of which were engaged in a new technology: home banking. The findings indicate that technological networking is the best predictor of technological innovation. They reveal also that firms with extensive networking are more likely to implement the innovation with strategic partners. Finally, the paper discusses the implications of the findings for organization design and proposes an expanded theoretical framework for organizational innovation.
The Informativeness of Stale Financial Disclosures

Investors have at their fingertips an almost unlimited supply of financial disclosures. Some of these disclosures are recently released, but most have been in the public domain for months or even years. In this study, we evaluate whether such “stale” disclosures continue to be informative to investors. Using a novel dataset that tracks search requests on the SEC EDGAR database, we find evidence that the acquisition of stale disclosures from EDGAR is positively associated with absolute returns and trading volume within the next two hours. We investigate several potential explanations for why investors might find previously released disclosures informative and we find evidence consistent with two explanations: first, investors appear to request stale information to provide context for new information releases; second, investors appear to request stale information to resolve cases of high prior information uncertainty. In addition, we do not find evidence that the relation between requests for stale disclosures and market activity is driven by unsophisticated investors. Our results highlight the value of historical disclosures and their archives to equity markets.
Internationalisation of Firms, Innovation and Productivity 1

This paper examines the effect of the internationalisation of firms via foreign direct investment and trade on their innovation and productivity performance. We use micro data from two waves of the Community Innovation Survey of enterprises in Ireland covering the period 2004-2008 and estimate a structural model to analyse the role of foreign direct investment and exporting in the relationships between innovation investment, innovation output and productivity. Our econometric results suggest that foreign affiliates and domestic exporters are more likely to invest in innovation and, conditional on investing in innovation, they are more likely to have successful innovation output and a higher productivity in comparison to firms that serve only the domestic market. While foreign linkages per se explain to a large extent the unconditional innovation output and productivity differentials, when we control for other factors, we find that the innovation output differential is accounted to a large extent by access to external knowledge flows while the productivity differential is mainly due to the fact that firms with foreign linkages are closer to the technology frontier.
The association of immunoreactive p53 and Ki-67 with T-stage, grade, occurrence of metastases and survival in renal cell carcinoma.

BACKGROUND The aim of this study was to clarify the association of p53 and Ki-67 protein expressions with tumor characteristics and survival in renal cell carcinoma (RCC). MATERIALS AND METHODS One hundred and seventeen patients were included in the study, 101 (86%) with conventional RCC according to the Heidelberg classification. Patients were divided into three groups with either primary metastases (pm), later metastases (lm), or no metastases (nm) during 7.5 years follow-up. Paraffin-embedded tissues were examined by immunohistochemistry utilizing anti-p53 and anti-Ki-67 antibodies, with a positive reaction cut-off of 10%. RESULTS In conventional RCC, there was more Ki-67 positivity in high T(tumor)-stage compared to low T-stage (p = 0.036) and in pm patients compared to nm patients (p = 0.007); p53 was not associated with T-stage or metastatic category. Coexpression of p53/Ki-67 was more common in pm patients than in lm patients, but was not observed in nm patients (p = 0.001). In the pm/lm group, p53 and Ki-67 expressions were associated with decreased survival (log-rank, p = 0.030 and p = 0.031, respectively). In lm patients, high T-stage (T3, T4) was associated with metastases-free survival (p = 0.034) and overall survival (p = 0.006). CONCLUSION p53 and Ki-67 expressions are associated with aggressive tumor phenotype and decreased survival in metastatic RCC. Ki-67 alone was a stronger prognostic marker than p53 for development of metastases. Double positivity for p53 and Ki-67 expression in RCC patients seems to indicate a high metastatic probability.
Value Creation at the Ongoing Consolidation of the European Banking Markets

The European banking landscape has experienced a profound restructuring since the mid 1980ties and still is substantially changing. In the last three years, prior to the formal start of the European Monetary Union, we counted more completed large mergers and acquisitions (M&A) than in the period between 1985 and 1997. We examine the value implications of 98 large national and international mergers and acquisitions of exchange listed European acquiring banks. Mergers and acquisitions with associated sectors, such as insurance and securities are considered as well. Effects are analyzed for the shareholders of the targets, the bidders and the combined entity of targets and bidders. We find, consistent with prior research, that the shareholders of the targets receive a considerable and significant positive revaluation of their shares. Effects for bidders are mostly insignificant. But, on an aggregate basis mergers and acquisitions of European banks do still create value. However, we detect a shift in results over time. European acquiring banks in large deals have experienced significant negative cumulated abnormal returns since 1998. Moreover, we find that in particular cross-border transactions of European banks seem to be value destroying.
Integrating Traditional Stock Trading Systems: A Data Mining Approach

 Abstract — This paper proposes a new stock trading approach which integrates all trading signals from six traditional trading systems: Moving Average Convergence/Divergence, Relative Strength Index, Stochastic Oscillator, Moving Average Envelopes, Bollinger Bands, and Commodity Channel Index. The combined signals are filtered by decision trees in order to improve the quality of the trading signals. Precision of the trading signals and annual rate of return are used as metrics to evaluate the proposed trading system. From the experimental results, precision of trading signals can be improved by decision tree learning. To evaluate performance of the proposed system, the system is compared to each individual of the six traditional trading systems and the buy-and-hold strategy. From the comparison, the purposed system can provides the highest annual rate of return. Thus, the proposed approach is very promising for stock trading.
Measuring the Gains from Government Export Promotion

Reports the findings of first academic study in an area of marketing importance and interest to both exporters and governments. Determines that the research's main thrust is concerned with finding a new quantitative method of establishing value or utility of official export services. States that co‐operation between exporters and government officials is essential for exporting success and one way to build co‐operation is to show, unequivocally, the value or utility of government export promotion. Documents that the Irish and Canadian governments have carried out cost‐benefit analysis which, ostensibly, provides a quantitative estimate in monetary terms both with respect to total operation and individual programmes, these results are discussed further. Uses user research to put together data, and to add weight, figures and tables are employed. Insists UK government export promotion services, like several others, are not subject to the market price mechanism, services are free (mostly), some havenominal cos.
Managing Rewards to Enhance Customer Lifetime Value

The goal of loyalty reward program is to retain customers who are profitable to the organization. However most airlines have very little understanding of their customers yet have a little knowledge about their most valuable passengers. This study is aimed to analyze financial aspects of customer value to the company in the context of aviation loyalty reward program in Indonesia. Financial value of customers is analyzed using CLV approach. Modeling of financial value of the members to the airline is developed by performing regression analysis of CLV against RFM and the associated socio-demographic characteristics of the members. This study used secondary data of customer profiles and financial transactions of the Garuda Frequent Flyer members in 2012. The empirical findings observed in this study explain that the financial value of the frequent flyer members to the airline is influenced by RFM, Gender, Age, and Frequent Flyer Tier levels. It is also found that the RFM valuation is aligned with CLV analysis. The result contributes to the knowledge of aviation loyalty program by improving the effectiveness from the aspect of capitalizing on the lifetime value of the members, and to the industry in designing proper marketing strategy and implementing accurate marketing functions in term of Frequent Flyer Program.
A Five-Component Customer Commitment Model

Empirical studies in marketing conceptualize commitment as a three-component construct comprised of affective, normative, and calculative commitment. We develop and empirically test a five-component typology of consumer commitment—affective, normative, economic, forced, and habitual commitment. The broadened conceptualization of commitment is tested using qualitative and quantitative studies with data from 9,000 consumers and 10 countries. The broadened five-component commitment model demonstrates high levels of reliability, convergent and discriminant validity, and stability, as well as unique associations with repurchase intentions. Managerially, it provides a roadmap for optimizing commitment: while forced commitment should be minimized, economic and habitual commitment should be enhanced. These prescriptions vary for goods and services. Namely, affective, normative, and habitual commitment exhibit stronger positive effects on repurchase intentions for goods than for services; the opposite pattern is found for economic commitment. By showing how managers should optimize specific commitment dimensions rather than simply maximize overall commitment, while accounting for contextual factors such as differences between goods and services, our results provide an actionable strategic blueprint for firms’ customer commitment strategy.

Garvicin A, a Novel Class IId Bacteriocin from Lactococcus garvieae That Inhibits Septum Formation in L. garvieae Strains

Lactococcus garvieae 21881, isolated in a human clinical case, produces a novel class IId bacteriocin, garvicin A (GarA), which is specifically active against other L. garvieae strains, including fish- and bovine-pathogenic isolates. Purification from active supernatants, sequence analyses, and plasmid-curing experiments identified pGL5, one of the five plasmids found in L. garvieae [M. Aguado-Urda et al., PLoS One 7(6):e40119, 2012], as the coding plasmid for the structural gene of GarA (lgnA), its putative immunity protein (lgnI), and the ABC transporter and its accessory protein (lgnC and lgnD). Interestingly, pGL5-cured strains were still resistant to GarA. Other putative bacteriocins encoded by the remaining plasmids were not detected during purification, pointing to GarA as the main inhibitor secreted by L. garvieae 21881. Mode-of-action studies revealed a potent bactericidal activity of GarA. Moreover, transmission microscopy showed that GarA seems to act by inhibiting septum formation in L. garvieae cells. This potent and species-specific inhibition by GarA holds promise for applications in the prevention or treatment of infections caused by pathogenic strains of L. garvieae in both veterinary and clinical settings.
