Factors affecting innovation in logistics technologies for logistics service providers in China

Purpose – With the fast growth in China's economy and China's accession into WTO, the demand for logistics services has been growing significantly in China. China's logistics service providers need to pay more attention to adopt more efficient logistics technologies to provide better services for their customers. The purpose of this paper is to study the factors affecting the innovation in logistics technologies for logistics service providers in China.Design/methodology/approach – Questionnaire survey on logistics service providers in Beijing, Shanghai and Shenzhen is conducted to study the innovation in logistics technologies by China's logistics industry. Logistics technologies are classified into four types: data acquisition technologies, information technologies, warehousing technologies, and transportation technologies. The influencing factors include internal and external factors. Regression analysis is used to analyze the influences of these factors on technological innovation.Findings – The innov.
Parsimoneous Modeling of Yield Curves for U.S. Treasury Bills

A new model is proposed for representinq the term to maturity structure of interest rates at a point in time.The model produces humped, monotonic and S-shaped yield curves using four parameters. Conditional on a time decay parameter, estimates of the other three are obtained by least squares. Yield curves for thirty-seven sets of U.S. Treasury bill yields with maturities up to one year are presented. The median standard deviation of fit is just over seven basis points and the corresponding median R-squared is . 96. Study of residuals suggests the existence of specific maturity effects not previously identified. Using the models to predict the price of a long term bond provides a diagnostic check and suggests directions for further research.
Hazard assessment of chemical carcinogens: the impact of hormesis

The recent report of reductions in the number and area of preneoplastic hepatic lesions in response to low doses of the tumor promoter phenobarbital provides important new support for the existence of hormetic responses to carcinogens. The presence of hormetic responses to carcinogenic agents and the corollary that beneficial doses of these compounds can be determined have several implications for the bioassay and hazard assessment of carcinogens as well as for public policy regulating exposure to these agents. To be adequately sensitive to detect and quantify hormetic or other non‐linear dose–response functions, current study designs must be modified to include lower doses and sufficiently large numbers of animals. Short‐ or medium‐term animal studies are a cost‐effective means of addressing these needs and have been used recently to describe a classical hormetic response to the non‐genotoxic carcinogen phenobarbital. These basic changes should be supported by a continuing emphasis on mechanistic research and the development of biologically based quantitative models of toxicant action. Linking these models with physiologically based pharmacokinetic model descriptions of target dose holds the greatest promise for improving the description of the dose–response curve at low doses. These approaches are generally encouraged by the USEPA in the form of The 1996 Proposed Carcinogen Risk Assessment Guidelines. However, there remain substantial questions regarding integration of the concept of hormesis into hazard testing and public policy that require careful consideration. Herein, we explore the issues that surround testing for hormetic responses and the implications for public policy. Copyright © 2000 John Wiley & Sons, Ltd.
Tagging and Income Taxation: Theory and an Application

We derive a set of analytical results for optimal income taxation with tags using quasilinear preferences and a Rawlsian social welfare function. Secondly, assuming a constant elasticity of labor supply and log-normality of the skills distribution, we analytically identify the winners and losers of tagging. Third, we prove that if the skills distribution in one group first-order stochastically dominates the other, tagging calls for redistribution from the former to the latter group. Finally, we calibrate our model to the US workers using gender as tag. Welfare implications are dramatic. Only male high-wage earners lose. Everyone else gains, some substantially.

Measuring the Deliverable and Impressible Dimensions of Service Experience

Service innovation has become a priority within the field of innovation management and is increasingly focused on creating memorable experiences that can result in customer loyalty. Studies of experience design suggest individual service elements to be managed when staging an experience, whereas conceptual models in the literature emphasize the holistic way in which an experience is perceived. In short, service experience is greater than the sum of its parts. Therefore, successful innovation management requires the ability to understand and measure the mechanisms by which service innovations impact customers' experiences. Our research addresses this need by identifying dimensions of service experience and developing a tool for their measurement. Using a three stage process of systematic literature review, rigorous scale development and reduction, and validation, we identify six dimensions of the service experience and develop scales to measure each one. This results in a model of service innovation that highlights the levers through which a company's service innovation efforts can result in memorable experiences and ultimately new service success.
Quantum Nondemolition Measurements

Some future gravitational-wave antennas will be cylinders of mass ∼100 kilograms, whose end-to-end vibrations must be measured so accurately (10–19 centimeter) that they behave quantum mechanically. Moreover, the vibration amplitude must be measured over and over again without perturbing it (quantum nondemolition measurement). This contrasts with quantum chemistry, quantum optics, or atomic, nuclear, and elementary particle physics, where one usually makes measurements on an ensemble of identical objects and does not care whether any single object is perturbed or destroyed by the measurement. This article describes the new electronic techniques required for quantum nondemolition measurements and the theory underlying them. Quantum nondemolition measurements may find application elsewhere in science and technology.
The Intertemporal Elasticity of Substitution in Consumption in the United States and the United Kingdom

As Robert E. Hall (1988) notes, the magnitude of the intertemporal elasticity of substitution in consumption is "one of the central questions of macroeconomics. " Do higher expected real interest rates lead to deferred consumption? The authors extend Hall's methodology and model, and compare results for the United Sta tes and the United Kingdom. In both cases, they directly estimate the mo ving average process that temporal aggregation might induce in the random disturbances and take account of consumers who do not follow the lif e cycle-permanent income model of consumption.

Financial Statement Fraud: Some Lessons from US and European Case Studies

This paper studies 14 companies which were subject to an official investigation arising from the publication of fraudulent financial statements. The research found senior management to be responsible for most fraud. Recording false sales was the most common method of financial statement fraud. Meeting external forecasts emerged as the primary motivation. Management discovered most fraud, although the discovery was split between incumbent and new management.
Pain associated with health and economic burden in France: results from recent National Health and Wellness Survey data

Purpose This study aimed to estimate the prevalence of pain among French adults and assess the impact of pain on health-related quality of life (HRQoL), activity impairment, and health care resource use (HRU). Patients and methods Respondents from the 2015 France National Health and Wellness Survey (N=19,173) were categorized by self-reported pain (experienced pain in the past 12 months vs no pain) and compared on HRQoL (36-Item Short Form Health Survey version 2: Mental Component Summary, Physical Component Summary, and Short Form-6 Dimensions health utilities), activity impairment (Work Productivity and Activity Impairment questionnaire), employment status, and HRU (health care provider visits, emergency room visits, and hospitalizations). Bivariate analyses examined differences between pain groups stratified by age, sex, income, and Charlson comorbidity index (CCI) scores. Results Pain prevalence was 20.2% (n=4007). Mean Physical Component Summary decrements with pain ranged from 3.4 to 8.1 points among those aged <35 years to those aged 45–54 years, respectively. Results for Mental Component Summary and Short Form-6 Dimensions scores followed similar patterns. Regardless of income, sex, or CCI group, pain was associated with significant decrements on all HRQoL measures (for all, p<0.05). The impact of pain on activity impairment was lowest among those <35 years; this impact was higher in middle age and then tapered off among those aged ≥75 years. Pain was associated with greater activity impairment and more health care provider visits across income, sex, and CCI groups (for all, p<0.05). Generally, emergency room visits were more common among those with pain across age, sex, and CCI, but they were only significantly associated with pain in the lower income group (p<0.01). Pain was associated with significantly more hospitalizations across age and income groups. Conclusion Results suggest pain negatively affects HRQoL, activity impairment, and HRU across demographic subgroups. These findings help underscore the considerable health and economic burden of pain in France.
Investigating the relationship of sustainable supply chain management with corporate financial performance

Purpose - – The purpose of this paper is to investigate whether companies’ environmental and social supply chain activities are associated with their financial performance. Design/methodology/approach - – A sample from the top 500 US companies based on Newsweek's green ranking is used. Data from the Bloomberg environmental, social and governance (ESG) and COMPUSTAT financial database are used for an empirical analysis of the relationships. Findings - – Integrated sustainable supply chain management, jointly including social and environmental supply chain management, efforts is positively associated with corporate financial performance measured by return on assets and return on equity, and the positive effects can have a time lag of at least two years. Research limitations/implications - – By adopting the ESG database, the paper only tests corporate sustainability supply chain management using a binary 0-1 valuation. Three-year data period is also a limitation for an extensive time study. A research implication is that win-win benefits may accrue, but additional nuances may exist such as indirect influences that need to be studied. Practical implications - – Two major implications of this study are that organizations may wish to implement both environmental and social supply chain management simultaneously to get the greatest benefit, and that managers need to be patient about reaping the rewards of these initiatives. Originality/value - – The paper contributes to the sustainability management literature by being the first to use publicly available data to investigate the financial benefits associated with individual and joint environmental and social supply chain management activities. The paper also uses a relatively large data set from US-based companies that have not been widely studied in the supply chain management literature.
AHP as an effective consensus-based selection tool: a case of personnel selection for the Ministry of Foreign Affairs in Saudi Arabia

While merits of normative judgements may be questionable when objectivity is the desired criterion in management decisions, which tend to be inherently unstructured such as personnel selection, evidence suggests that the perspective of traditional personnel selection methods remains relatively restrictive and subjective. The analytic hierarchy process (AHP) has emerged as a powerful addition to the decision-support tools for providing a systematic approach to solving an inherently unstructured problem. However, despite its relevance to personnel selection, application of the AHP has been surprisingly missing in this decision area. This paper develops the AHP model as an alternative approach to the traditional personnel selection methods that minimises subjective judgements. The model is illustrated by its implementation in the Saudi Ministry of Foreign Affairs. The paper concludes with implications for managerial decision-making.
Using efficiency measures to distinguish among alternative explanations of the structure-performance relationship in banking

Prior research on the structure‐performance relationship has not investigated all of the relevant relationships among market structure, profits, prices, and explicitly calculated measures of firm efficiency. This paper replicates the four approaches in the literature, adds several innovations, and applies the analysis to banking data. We find more support for the structure‐conduct‐performance hypothesis than for the relative‐market‐power and efficient‐structure hypotheses, although the data are not fully consistent with any of these theories. We also find support for Hick's quiet‐life hypothesis, which implies that firms with market power adhere less rigorously to efficiency maximization. J.E. L.

Are They Still Called Late? The Effect of Notice Period on Calls of Convertible Bonds

The notice period given to convertible bondholders affects the optimal call policy for convertible bonds. After accounting for the notice period, convertible bonds in our sample would have been optimally called when the stock was at about an 11% premium (median) relative to the conversion price. We find that convertible bonds are, on average, not called later than optimal. The average (median) excess call premium is only 2.65% (1.71%) for those bonds without binding call protection. These values are statistically indistinguishable from zero and are substantially less than the 26%-44% call premium found by previous researchers.
Research Joint Ventures

Inter-firm collaboration is not new. What is new is that such collaboration has exploded during the past couple of decades, in parallel to the intensification of international competition. Moreover, the nature of collaboration has changed, shifting from peripheral interests to the very core functions of the corporation, and from equity to non-equity forms of collaboration. Importantly, cooperation focusing on the generation, exchange, and/or adaptation of new technologies has risen at very fast rates. Research joint ventures, the focus of this paper, belong in the latter category. Copyright Blackwell Publishing Ltd, 2003.
Presenting Structural Innovation in an Institutional Environment: Hospitals' Use of Impression Management

This research examines how the first organizations to abandon an institutionalized, taken-for-granted structure and adopt a radically different form presented the innovation to important stakeholders. A content analysis of hospitals' annual reports reveals that organizations that differed on other dimensions uniformly made preventive use of defensive impression management in announcing the change to a diversified corporate structure. The organizations invoked coercive and mimetic pressures to account for and justify the new structure, and they associated the innovation with legitimated organizational activities. The findings make two contributions that link the “old” institutionalism and neoinstitutionalism: they point to organizational agency in the preventive use of the very institutional forces that create isomorphism and suggest the presence of institutional forces even during the early stages of innovation.
An Examination of Empirical Tests of Social Security and Savings

The effect of social security and other forms of government debt on national savings is one of the most widely debated policy questions in economics today. Some estimates suggest that social security has reduced U.S. savings by almost forty percent. This paper examines recent cross-section and time series empirical tests of the social security-savings question and argues that, given current data, neither type of test has much potential for settling the controversy. In particular, there are a number of specification problems relating to social security time series regressions that can easily lead to highly unstable coefficients and to rejection of the hypothesis that social security reduces savings, even if it is actually true. These points are demonstrated by running regressions on hypothetical data generated by a perfect foresight life-cycle growth model developed previously by the authors. While the data is obtained from a model in which social security reduces the nation's capital stock by almost twenty percent, time series social security regression coefficients vary enormously depending on the specified level of the program, the preferences of hypothetical households, the level of concommitant government policies, and the time interval of the data.
The Effects of Outsourcing on the Elasticity of Labor Demand

In this paper, I focus on the effects of outsourcing on conditional labor demand elasticities. I begin by developing a model of outsourcing that formalizes this relationship. I show that the increased possibility of outsourcing (modeled as a decline in foreign intermediate input prices and an increase in the elasticity of substitution between foreign and domestic intermediate inputs) should increase labor demand elasticities. I also show that, a decline in the share of unskilled labor, due either to skill biased technological change or to movement of unskilled labor intensive stages abroad, can work in the opposite direction and reverse the increasing trend in elasticities. I then test the predictions of the model using the U.S. Census Bureau's Longitudinal Research Database (LRD). The instrumental variable approach used in the estimation of labor demand equations is the main methodological contribution of this paper. I directly address the endogeneity of wages in the labor demand equation by using average non-manufacturing wages for each location and year as an instrumental variable for the plant-level wages in the manufacturing sector. The results support the main predictions of my model. U.S. manufacturing plants operating in industries that heavily outsource experienced an increase in their conditional labor demand elasticities during the 1980-1992 period. After 1992 elasticities began to decrease in outsourcing industries. This finding is consistent with the model which suggests that a decline in the share of unskilled labor in total cost could result in such a decrease in labor demand elasticities, precisely when the level of outsourcing is high. Estimates at the two-digit industry level provide further evidence in support of the hypothesis that heavily outsourcing industries experience greater increases in their elasticities.
Dreams and Age

This work evaluated the association of age and dream reports. The verbal reports of 148 dreams of elderly people (M age = 75.8 yr.) were compared with 151 dreams of a group of young people (M age = 22.0). The dreams were analyzed according to the Jungian vision (which looks at the dream as a text produced by the dreamer's unconscious while sleeping), using processing techniques derived from textual analysis. Significant differences were found between the number of words denoting emotion, with the young people reporting more explicit statements regarding emotional states. Significant differences were found also in use of verb tenses. When older people explicitly expressed an emotional state in a dream text, they shifted between present and past tense more frequently than young people. A significant prevalence in the semantic field of visual sense was evident as younger subjects used more sentences referring to sight than the elderly participants.
The effects of lutein on cardiometabolic health across the life course: a systematic review and meta-analysis.

BACKGROUND The antioxidant lutein is suggested as being beneficial to cardiometabolic health because of its protective effect against oxidative stress, but evidence has not systematically been evaluated. OBJECTIVE We aimed to evaluate systematically the effects of lutein (intake or concentrations) on cardiometabolic outcomes in different life stages. DESIGN This is a systematic review with meta-analysis of literature published in MEDLINE, Embase, Cochrane Central, Web of Science, PubMed, and Google Scholar up to August 2014. Included were trials and cohort, case-control, and cross-sectional studies in which the association between lutein concentrations, dietary intake, or supplements and cardiometabolic outcomes was reported. Two independent investigators reviewed the articles. RESULTS Seventy-one relevant articles were identified that included a total of 387,569 participants. Only 1 article investigated the effects of lutein during pregnancy, and 3 studied lutein in children. Furthermore, 31 longitudinal, 33 cross-sectional, and 3 intervention studies were conducted in adults. Meta-analysis showed a lower risk of coronary heart disease (pooled RR: 0.88; 95% CI: 0.80, 0.98) and stroke (pooled RR: 0.82; 95% CI: 0.72, 0.93) for the highest compared with the lowest tertile of lutein blood concentration or intake. There was no significant association with type 2 diabetes mellitus (pooled RR: 0.97; 95% CI: 0.77, 1.22), but higher lutein was associated with a lower risk of metabolic syndrome (pooled RR: 0.75; 95% CI: 0.60, 0.92) for the highest compared with the lowest tertile. The literature on risk factors for cardiometabolic diseases showed that lutein might be beneficial for atherosclerosis and inflammatory markers, but there were inconsistent associations with blood pressure, adiposity, insulin resistance, and blood lipids. CONCLUSIONS Our findings suggest that higher dietary intake and higher blood concentrations of lutein are generally associated with better cardiometabolic health. However, evidence mainly comes from observational studies in adults, whereas large-scale intervention studies and studies of lutein during pregnancy and childhood are scarce.
Scientists as Midwives to Cluster Emergence: An Institutional Work Framework

The question of how embedded actors can create institutions that support cluster emergence remains unsolved in the cluster and national innovation systems literature. The present paper extends the recent literature on institutional entrepreneurship and institutional work to solve this paradox of embedded agency in the context of science-based clusters. Building on a longitudinal single case study of a functional foods cluster in Finland, we present an institutional work framework for cluster formation. We argue that, in addition to ideational, material and bridging work, authentic leadership work is critical for cluster emergence. The results of the study highlight the opportunities that scientists have to act as midwives to cluster formation, but they also show that well-functioning clusters need a broader support base.
