The Influence of Marketing Journals: A Citation Analysis of the Discipline and its Sub-areas

An important characteristic of journals is how influential they are in the generation and dissemination of scholarly knowledge in a discipline.We report a citation analysis of 49 marketing and marketing-related journals to assess their relative influence based on the index of structural influence proposed by Salancik (1986). We investigate the level and span of influence of the 49 journals, both in the marketing discipline as a whole and in five specific sub-areas of marketing.As expected, the Journal of Marketing emerges as the most influential journal in the discipline and as the journal with the broadest span of influence across all sub-areas of marketing.However, different journals are most influential in each of the sub-areas, and the Journal of Marketing is particularly influential among the applied marketing journals.We also find that the index of structural influence is significantly correlated with all other measures of influence but least so with the impact factors reported in the Social Sciences Citation Index.
MFS-LDA: a multi-feature space tag recommendation model for cold start problem

Tags are used to annotate resources on social media platforms. Most tag recommendation methods use popular tags, but in the case of new resources that are as yet untagged (the cold start problem), popularity-based tag recommendation methods fail to work. The purpose of this paper is to propose a novel model for tag recommendation called multi-feature space latent Dirichlet allocation (MFS-LDA) for cold start problem. ,MFS-LDA is a novel latent Dirichlet allocation (LDA)-based model which exploits multiple feature spaces (title, contents, and tags) for recommending tags. Exploiting multiple feature spaces allows MFS-LDA to recommend tags even if data from a feature space is missing (the cold start problem). ,Evaluation of a publicly available data set consisting of around 20,000 Wikipedia articles that are tagged on a social bookmarking website shows a significant improvement over existing LDA-based tag recommendation methods. ,The originality of MFS-LDA lies in segregation of features for removing bias toward dominant features and in synchronization of multiple feature space for tag recommendation.
The Credibility of Open Market Share Repurchase Signaling

Open market share repurchase announcements are commonly associated with equity undervaluation, but their signal about firm value can often be misleading. We conjecture that executives who buy shares of their firm before an announcement add credibility to the undervaluation signal. Consistent with this hypothesis, we find that announcement returns are positively related to past insider purchases, especially for firms that are priced less efficiently. Firms whose insiders bought more shares are also more likely to complete their repurchase plans. Finally, we find that insider purchases predict post-announcement stock returns.
Using wavelet spectrum analysis to resolve breaking events in the wind wave time series

This paper presents the development of a new approach, based on wavelet spectrum analysis, for the de- tection of breaking waves in a time series of surface wave fluctuations. The approach is shown to be capable of produc- ing equivalent wave breaking statistics as field measurements based on detection of whitecaps at a fixed point of observa- tion. This wavelet-based approach is applicable to both deep water and finite depth environments. Based on applications of this approach to the analysis of available field data, a novel classification of wave breaking processes that consists of in- cipient, developing, and subsiding phases is proposed.
Economic development and structural change: The role of the service sector

This paper provides evidence on patterns of structural change during development, examining in particular how cross‐section studies can accommodate the recent evidence on ‘de‐industralisation’ in many developed countries. It is argued that functional forms used previously are now inappropriate and new functional forms are proposed. It is found, using these functional forms, that empirical evidence supports the existence of clear patterns of structural change across developed and developing countries.
Total synthesis of (±)-aspidophylline A.

A total synthesis of aspidophylline A, a pentacyclic akuammiline-type monoterpene indole alkaloid, is described. The synthesis features: 1) rapid access to a fully functionalized dihydrocarbazole through the desymmetrization of readily available 2-allyl-2-(o-nitrophenyl)cyclohexane-1,3-dione; 2) an intramolecular azidoalkoxylation of an enecarbamate to install both the furoindoline ring and the azido functionality; and 3) an intramolecular Michael addition for the construction of the 2-azabicyclo[3.3. 1]nonane ring system.
The Cost of Equity Capital on Developing Equity Markets: Estimations for Selected Slovene Companies

The Cost of Equity Capital on Developing Equity Markets: Estimations for Selected Slovene Companies The article sheds light on the estimation of the cost of equity capital on a developing equity market. The cost of equity is important; it is crucial in capital budgeting decisions and performance evaluation. It determines the minimum yield the investors require on the invested capital and we use it as a discount rate to calculate the present value of the expected free cash flows to equity. The aim of this paper is to tackle the estimation of the cost of equity capital on developing markets with the example of estimation for ten Slovene publicly traded companies. The estimated cost of capital for the selected Slovene companies is between 9,7% and 13,7%.
Endogenous Timing in Contests with Delegation

We study two‐player contests in which each player hires a delegate, and the delegates decide endogenously when to expend their effort. First, we look closely at the delegates' decisions on when to expend their effort, given contracts between the players and the delegates, and look at the players' decisions on their contracts. Then, we compare the outcomes of the endogenous‐timing framework with those of the simultaneous‐move framework. We show that the higher‐valuation player offers her delegate greater contingent compensation than her opponent, the delegate of the higher‐valuation player chooses his effort level after observing his counterpart's, the equilibrium expected payoff of the delegate of the higher‐valuation player is greater than that of his counterpart, and economic rent for each delegate exists. We show that, in the endogenous‐timing framework, each player offers her delegate better contingent compensation, each delegate's expected payoff is greater, and each player's expected payoff is smaller, as compared with the simultaneous‐move framework.
Visuospatial impairment in Parkinson's disease: The role of laterality

Asymmetry is one of the unique and mysterious features of Parkinson's disease (PD). Motor symptoms develop unilaterally either on the left (LPD) or the right side (RPD). Incongruent data are available whether the side of onset has an impact on cognition in PD. The objective of this study is to compare the visuospatial performance of RPD and LPD patients. Seventy-one non-demented, non-depressive and right-handed patients were categorized into RBD (n = 36) and LPD (n = 35) groups. Rey-Osterrieth Complex Figure Test (ROCF) was evaluated by both the Taylor's and Loring's scoring systems. Subsequently, we also performed subgroup analyses on patients having short disease duration (≤5 years, 15 RBD and 15 LPD patients). The standard analysis of ROCF (Taylor's system) did not reveal any differences; however, the utilization of the Loring's system demonstrated that LPD patients had significantly worse visuospatial performance than the RPD subjects (3.0 vs. 2.0 points, median, p = 0.002). Correlation between the number of spatial errors and the degree of asymmetry was significant (r = −0.437, p = 0.001). However, this difference could not be observed in PD patients with short disease duration. LPD patients had worse visuospatial performance than the RPD subjects and the number of errors tightly correlated with the degree of asymmetry and long disease duration.
Real-time ultrasound guidance for percutaneous transluminal retrieval of nonopaque intravascular catheter fragment.

Successful percutaneous transluminal retrieval of intravascular catheter fragments has been reported [1 -4]. A prerequisite for this technique is that the catheter fragments be radiopaque. Percutaneous retrieval of nonopaque yenous catheter fragment with real-time ultrasound guidance has not been previously reported. The technique offers a preferred alternative to exploration in these often critically ill patients.
Stable subclones of the chondrogenic murine cell line MC615 mimic distinct stages of chondrocyte differentiation

Fourteen stable subclones derived from the murine chondrogenic cell line MC615 were established and characterised regarding their differentiation stages and responsivity to BMP2. Based on their gene expression profiles which revealed remarkable variances in Col2a1 and Col10a1 expression, subclones could be grouped into at least three distinct categories. Three representative subclones (4C3, 4C6 and 4H4) were further characterised with respect to gene expression pattern and differentiation capacity. These subclones resembled (i) weakly differentiated chondrogenic precursors, strongly responding to BMP2 stimulation (4C3), (ii) collagen II expressing chondrocytes which could be induced to undergo maturation (4C6) and (iii) mature chondrocytes expressing Col10a1 and other markers of hypertrophy (4H4). Interestingly, BMP2 administration caused Smad protein phosphorylation and stimulated Col10a1 expression in all clones, but induced Col2a1 expression only in precursor‐like cells. Most remarkably, these clones maintained a stable gene expression profile at least until the 30th passage of subconfluent culture, but revealed reproducible changes in gene expression and differentiation pattern in long term high density cultures. Thus, the newly established MC615 subclones may serve as a potent new tool for investigations on the regulation of chondrocyte differentiation and function. J. Cell.

Does Ownership Matter for Employee Motivation When Occupation Is Controlled for?

The public service motivation literature argues that public employees are more motivated than private employees to deliver public service for the benefit of society. But the reason for this may be that the classical welfare services are predominant in the public sector. This article therefore investigates if ownership matters to employee motivation when occupation is controlled for. The findings show that the employees in both sectors have pro-social motivation, but that public sector employees are more motivated to work for the public interest, whereas private sector employees are more motivated to help individual users of services. The survey data are based on 3,304 Danish employees working in private as well as public organizations.
The Profitability of Merger Arbitrage: Some Australian Evidence

In this paper we examine the risk-adjusted profitability of merger arbitrage in Australia. Using a sample of 193 merger and acquisition bids from January 1991 to April 2000, we construct a time series of returns on equal and value-weighted merger arbitrage portfolios. Benchmarking the returns on the merger arbitrage portfolios against the CAPM and Fama and French (1993) three-factor models, we find that merger arbitrage generates statistically and economically significant excess risk-adjusted returns before transaction costs, ranging from 0.84% to 1.20% per month. However, after adjusting for transaction costs, the risk-adjusted returns are no longer statistically significant Further, in contrast to the United States, our evidence indicates that merger arbitrage in Australia is a market-neutral investment strategy. Indeed, the results from our estimations of the linear CAPM and Fama and French (1993) three-factor models suggest that merger arbitrage returns are not significantly sensitive to market-wide factors.
Applying fuzzy support vector machine to predict membrane protein interactions with different representations

Membrane protein interactions are involved in the regulation and execution of all biochemical pathways within the cell. It is crucial to identify the binding partners for understanding the function of an uncharacterized protein, and when these partners turn out to have known function, deductions about the potential role of the uncharacterized protein can often be made. However, the analysis of interactions between membrane proteins is difficult because of the hydrophobic nature of these proteins, and conventional biochemical and genetic assays are often of limited use. In this paper, a novel method is presented for the prediction of membrane protein interactions representing the interactions with different features. We adopt fuzzy support vector machine as our classifier. Jackknife tests on the working datasets indicate that the precision, sensitivity and accuracy are improved greatly. The results show that the proposed method is efficient to genetically predict membrane protein interactions.
Leaders and leadership – many theories, but what advice is reliable?

Purpose – The paper seeks to use the experience of the author, a veteran consultant and author of many articles on leadership, who aims to summarize several fundamental concepts that have shaped the current debate about leaders and leadership. The author's goal is to dispel some leadership myths and offer some advice to leaders about how to perform more effectively in their roles.Design/methodology/approach – Taking the long view, the author concludes that leadership actually emerges or develops over time – not at a unique specific instant. It seems to appear and then disappear; it is elusive.Findings – Invisible forces act on the leadership process: the expectations of the followers, the culture of the organization and the circumstances. The task at hand and the context seem to dictate when and how leadership appears. The leadership dynamic thus depends on the situation.Practical implications – The primary role of the leader must be to develop a culture that enables individuals to coalesce around the sha.
The Determinants of Entrepreneurship in a Conflict Region: Evidence from the Chittagong Hill Tracts in Bangladesh

Abstract The Chittagong Hill Tracts (CHT) region in Bangladesh is a conflict-torn area. This paper aims to identify the determinants of entrepreneurship at the household level in the CHT region and contrast these with the determinants of entrepreneurship in the non-conflict mainland region. The analysis is based on the Household Income and Expenditure Survey 2005 data set (N=10,080). Using descriptive statistics and probit regression results, it is found that the probability that a household will own a business in the CHT region is 11 percentlower in comparison to that of a household elsewhere in Bangladesh. Moreover, starting a business in the CHT region requires more capital, and violent conflict and geo-cultural characteristics are particularly discouraging for entrepreneurship.
Protein Deficiency and the Growing Rat Lung. II. Morphometric Analysis and Morphology

ABSTRACT: Effects of protein deficiency during the whole period of postnatal development and intensive growth were studied in the rat lung parenchyma. Dams received a low protein diet as follows: early restriction, 8% casein diet from parturition, and delayed restriction, 12% then 8% casein diet from lactation d 8. After weaning (d 21), early restriction and delayed restriction group rats were maintained on the 8% casein diet until d 49, wherefrom they were returned to normal food (18% casein) for 11 wk. Lungs were processed for light and electron microscopic morphometry on d 21, 49, and 126. The diffusion capacity of the lung for O2 (DLO2) was also determined from the morphologic parameters. Volume and surface densities of the parenchymal components of malnourished rats did not consistently differ from controls. Because of lower lung volumes, absolute values, including DLO2, were all significantly decreased. Further, although lung volume growth was less impaired than body growth and thus deviated from the normal allometric relationship, most morphometric parameters paralleled body weight changes. Visually, we detected minor morphologic alterations at d 21 and 49, not necessarily reflected by morphometric data. But, importantly, lung parenchyma appeared mature at weaning despite the growth retardation. Normal refeeding resulted in a striking regrowth of the lung parenchyma. Although early restriction rats did not fully catch up in lung volume, most parenchymal parameters and DLO2 were largely restored in both refed groups.
Swap rate variance swaps

We study the hedging and valuation of generalized variance swaps defined on a forward swap interest rate. Our motivation is the fundamental role of variance swaps in the transfer of variance risk, and the extensive empirical evidence documenting that the variance realized by interest rates is stochastic. We identify a hedging rule involving a static European contract and the gains of a dynamic position on forward interest rate swaps. Two distinguishing features arise in the context of interest rates: the nonlinear and multidimensional relationship between the values of the dynamically traded contracts and the underlying swap rate, and the possible stochasticity of the interest rate at which gains are reinvested. The combination of these two features leads to additional terms in the cumulative dynamic trading gains, which depend on realized variance and are taken into consideration in the determination of the appropriate static hedge. We characterize the static payoff function as the solution of an ordinary differential equation, and derive explicitly the associated dynamic strategy. We use daily interest rate data between 1997 and 2007 to test the effectiveness of our hedging methodology in arithmetic and geometric variance swaps and verify that the hedging error is small compared with the bid–ask spread in swaption prices.
Impact of Venture Capital Investment Syndication on Enterprise Lifecycle and Success

The article investigates the impact of venture capital investment and investment syndication on enterprise lifecycle and success using the exit history of venture capital backed companies in Australia. It is observed that the venture capital backed companies tend to outperform those which are not while companies receiving syndicated venture capital investment tend to outperform the other venture capital backed companies. Based on the classic venture capital investment theory, we argue that venture capitalists essentially engage in superior venture selection through pre-investment screening and contribute to entrepreneurial development through post-investment monitoring and value creation. We then empirically investigate the lifecycle of the Australian venture capital backed companies from company formation to first venture capital financing round to exit. Survival duration of the ventures, investment growth and exit status are specifically analysed to capture the lifecycle. The findings show that the survival duration prior and post venture capital investment, venture capital investment growth in successive rounds and investment syndication increase the probably of success for the ventures.
How complete and accurate are cancer registrations notified by the National Health Service Central Register for England and Wales?

STUDY OBJECTIVE To assess the completeness and accuracy of notification of cancers by the National Health Service Central Register (NHSCR) for England and Wales. DESIGN Comparison of 720 cancer registrations ascertained from NHSCR up to May 1999 with those ascertained for the same cohort from six other sources and a pathology review of the NHSCR cancer registrations. PARTICIPANTS People born in Cumbria, north west England, 1950–89, and diagnosed with cancer throughout the UK, 1971–1989. MAIN RESULTS Cancer diagnoses notified by NHSCR differed substantially from those determined by this pathology review for 47 of the 688 notified cases reviewed (7%; 95% CI 5%, 9%). Over one third of these discrepancies were attributable to failures in data capture or coding by the cancer registration system and almost half to changes in diagnosis; 26 of the 47 discrepant cases were reclassified as non-malignant and 21 as malignancies but with a substantially different diagnosis. The 694 confirmed malignancies represented 94% (95%CI 92%, 95%) of the 740 cancers ascertained from all sources. CONCLUSIONS It is estimated that the cancer registration system missed at least 10% (95%CI 6%, 15%) of all incident cases of malignant disease. Without additional ascertainment from multiple sources and diagnostic review, it would be incautious to use NHSCR cancer registrations as the sole basis of an epidemiological study.
Union–management interface: Using the competing values framework as a diagnostic tool to bring increased involvement at the plant level

This article describes an organizational intervention jointly sponsored by the United Automobile Workers and the Ford Employee Involvement Executive Committee. The intervention was needed to rejuvenate the existing employee involvement (EI) process which had been in existence since the early 1980s. The EI process had achieved its purpose of making significant cultural changes at Ford, but was viewed as narrow in scope in light of existing organizational problems of quality, customer focus, and productivity. An organizational intervention was designed jointly by a committee of union and management personnel using the Competing Values Framework as a diagnostic tool to examine the current organizational gaps in the majority of Ford's manufacturing facilities. The article discusses the overall process and the significant results at four major plant facilities. © 1993 by John Wiley & Sons, Inc.
Gonadotropin Binding Sites in Human Ovarian Follicles and Corpora Lutea During the Menstrual Cycle

Gonadotropin binding sites were localized by autoradiography after incubation of human ovarian sections with 125I-labeled gonadotropins. The binding sites for 125I-labeled human follicle-stimulating hormone (125I-hFSH) were identified in the granulosa cells and in the newly formed corpora lutea. The 125I-labeled human luteinizing hormone (125I-hLH) binding to the thecal cells increased during follicular maturation, and a dramatic increase was preferentially observed in the granulosa cells of the large preovulatory follicle. In the corpora lutea, the binding of 125I-hLH increased from the early luteal phase and decreased toward the late luteal phase. The changes in 3β-hydroxysteroid dehy-drogenase activity in the corpora lutea corresponded to the 125I-hLH binding. Thus, the changes in gonadotropin binding sites in the follicles and corpora lutea during the menstrual cycle may help in some important way to regulate human ovarian function.
Mice Lacking the ISG15 E1 Enzyme UbE1L Demonstrate Increased Susceptibility to both Mouse-Adapted and Non-Mouse-Adapted Influenza B Virus Infection

ABSTRACT ISG15 functions as a critical antiviral molecule against influenza virus, with infection inducing both the conjugation of ISG15 to target proteins and production of free ISG15. Here, we report that mice lacking the ISG15 E1 enzyme UbE1L fail to form ISG15 conjugates. Both UbE1L−/− and ISG15−/− mice display increased susceptibility to influenza B virus infection, including non-mouse-adapted strains. Finally, we demonstrate that ISG15 controls influenza B virus infection through its action within radioresistant stromal cells and not bone marrow-derived cells. Thus, the conjugation of ISG15 to target proteins within stromal cells is critical to its activity against influenza virus.
