From mass production to flexible/agile production

In industrial management, the 1980s marked the end of the twentieth century, an epoch dominated by US manufacturers, the alleged masters of mass production. This system has now been outstripped in several dynamic sectors by flexible/agile production. Increases in the pace of technological progress, training and aspirations have made the modern context so dynamic that firms which manage to harness the creativity and initiative of a good part of their workforce have an advantage over those that can only count on the input of their experts and managers. In sectors undergoing relatively broad and rapid change, twenty‐first century firms must adopt a more flexible and innovative type of organization to achieve manufacturing excellence.
Liberalisation, FDI, and productivity spillovers—an analysis of Indian manufacturing firms

The objective of the intensification of reforms in India's trade, technology and industry policies in 1991 was to make Indian industry competitive. In the light of these attempted changes, the present paper tested two hypotheses, namely (a) whether liberalisation has improved the productivity of local firms; and (b) whether the spillovers from technology transfer have increased in the liberal regime. To test these, techniques from panel data and stochastic production frontier were employed on 487 firms belonging to 24 three-digit manufacturing industries for the period 1989--90 to 1996--97. The results showed that after liberalisation, the productivity of Indian industry, especially the foreign owned firms, has improved. The econometric results suggested that only 'scientific' non-FDI firms have benefited from the liberalisation. For the 'non-scientific' firms, the impact is found to be productivity depressing. With respect to spillovers, only those domestic firms, which invested in R&D to decode the spilled knowledge, could benefit. Copyright 2002, Oxford University Press.
The inflammatory cell influx and cytokines changes during transition from acute inflammation to fibrous repair around implanted materials

The inflammatory and fibrous responses in a subcutaneous rat model were evaluated around degradable polyurethane urea (PUUR; Artelon®), with titanium and tissue culture polystyrene (PS) discs having different surface chemical properties but similar surface topography. Cytokines, viability, cellular response, differentiation of cells and fibrous capsule formation and vascularization was investigated after 1, 7 and 21 days of implantation. The exudates retrieved from the pockets were analysed with respect to the total cell numbers, the proportions of cell types, the differentiation of monocytes/macrophages (ED1, ED2), the DNA content and the viability (LD, Trypan blue). Tumour necrosis factor alpha ((h)TNF-α) and interleukin-10 ((h)IL-10) were quantified by ELISA. The number of blood vessels, blood vessel luminal area, blood vessel distribution and the fibrous capsule thickness were analysed. The highest number of cells in the exudates around all implants was detected during the early phase of healing (1–7 days). The proportion of ED2-positive cells in the exudates increased from 2–8% at 1 day to 43–56% at 21 days. The levels of TNF-α were low with a decrease at 7 days. After 21 days high amounts of IL-10 in the exudates were detected, in particular around PUUR. This study shows that the transition from inflammation to repair (1–21 days) around PUUR, Ti and PS materials was characterized by a decrease in inflammatory cell influx, an increasing proportion of ED2-expressing macrophages, a biphasic TNF-α secretion, an increase of IL-10 and a fibrous capsule formation similar to all materials tested.
Using Happiness Data for Environmental Valuation: Issues and Applications

In addition to standard methods of environmental valuation, a novel approach has recently emerged which models individuals' self-rated happiness as a function of their incomes and the prevailing environmental conditions. The estimated relationship is used to calculate the trade-off people would be willing to make between income and environmental conditions, i.e. the increase in income necessary to compensate individuals for any given decline in environmental quality. While the basic idea is simple, the theoretical and empirical details may be complex, and they may vary from application to application. This paper discusses the relevant conceptual and methodological issues and reviews applications to air and water pollution, noise nuisance, climate parameters, and natural hazards.
A Commentary on Risk Reduction by Geographic Diversification

The relationship between multinationality and value is still one of the most fundamental questions in IB research. Gande, Schenzler, and Senbet (2009) claim to have found empirical evidence for the incomplete capital markets theory (ICMT), which stipulates that investors value corporate multinationality due to its risk‐reducing effect. We show here that their findings do not support the hypothesis that investors value geographical diversification at the firm level because of its risk reducing effect. Further, a review of extant research shows that empirical results concerning the valuation impact of the risk‐reducing effect of geographical diversification at the firm level have to be regarded with caution due to conceptual and methodological inconsistencies. Consequently, this paper proposes several methodological refinements.
Antihyperglycemic and hypolipidemic effects of Costus speciosus in alloxan induced diabetic rats

Hyperglycemia, abnormal lipid and antioxidant profiles are the most usual complications in diabetes mellitus. In the present study, the antihyperglycemic, antihyperlipemic and antioxidant potency of an ethanol extract of Costus speciosus root was investigated in alloxan‐induced diabetic male (Charles Foster) rats. Four groups of alloxan diabetic rats (n = 6) were administered orally with different doses of Costus speciosus root extract (150, 300 and 450 mg/kg BW) and a standard drug, glibenclamide (600 µg/kg BW), for 4 weeks. Two groups of rats (n = 6) served as normal and diabetic controls. While the diabetic controls showed significant abnormal carbohydrate, lipid and antioxidant profiles, administration of 150 mg/kg BW dose neither improved glucose nor lipid metabolism and antioxidant levels. Administration of 300 and 450 mg/kg BW doses, however, resulted in a reversal of diabetes and its complications. Both doses significantly brought down blood glucose concentration (26.76%, 34.68%), increased glycogenesis and decreased glyconeogenesis bringing the glucose metabolism toward normalcy. These doses also reversed the hyperlipidemia by reducing plasma total lipid (12.87%, 178.24%), cholesterol (21.92%, 30.77%) and triglyceride (25.32%, 33.99%) and improved hepatic antioxidant enzyme activities. The high dose (450 mg/kg BW) was found to have more potential antioxidant activities compared with glibenclamide. It is concluded that Costus speciosus root extract possesses anti‐hyperglycemic, antihyperlipemic and antioxidative effects, which may prove to be of clinical importance in the management of diabetes and its complications.

Price and income elasticities of disaggregated import demand: results from UECMs and an application

This paper presents an empirical analysis of the demand for maize, milk powder, butter, and rice imports in Cyprus, using annual time series data covering the period 1975-1994. None of these products is produced in Cyprus and all the necessary quantities are imported to meet domestic demand. The primary objective of the paper is to derive long-run price and income elasticities of import demand that can be used to analyse the impact of various policies such as the adoption of the Common Agricultural Policy (CAP) when, and if, the Republic of Cyprus joins the European Union (EU). In so doing the paper takes on board some recent developments in time series econometrics. The cointegration test used (the 'bounds' test) is a recent test and is based on the estimation of an unrestricted error-correction model (UECM). Parsimonious models were derived using Hendry's 'general to specific' approach. The estimated elasticities were subsequently used to quantify some of the implications for Cyprus had the CAP been operational in 1994.
Limited Records and Reputation

We study the impact of limited records on reputation dynamics, that is, how the set of equilibria and equilibrium payoffs changes in a model in which one long-lived player faces a sequence of short-lived players who observe only limited information about past play (the last K periods of the long-lived player's actions). We show that limited records dramatically change the equilibrium behavior. Moreover, with limited records, equilibria in games with complete and incomplete information are strikingly different (in contrast to games with complete records). We also obtain a lower bound for equilibrium payoffs at any moment of the game, not only at the beginning, thus providing a stronger long-run prediction.
Can management be taught

The topic whether management skills are communicable has been the topic of scholars' debates and broad examination through literature in the last decades. However, there is less literature focusing on solutions for successful management education. This paper, not only takes up a position that management can be taught and learned, but also examines how the learning process is approached. The paper discusses characteristics of successful management educators and determine their impacts on management development. The paper determines the qualities and skills that modern managers must develop, especially in this time of globalization and rapid change in the business world. It suggests educating managers in “soft skills” such as interpersonal and intrapersonal skills and not merely concentrating on the “hard skills”, such as analytical skills. Additionally in this work, the need for managers with international exposure and cross‐cultural experience is emphasized. Finally, a proposal for management education curricula is tabled and address the issue of limits of management education is addresed.
Dendritic Cells as Pharmacological Tools for Cancer Immunotherapy

Although the earliest—rudimentary—attempts at exploiting the immune system for cancer therapy can be traced back to the late 18th Century, it was not until the past decade that cancer immunotherapeutics have truly entered mainstream clinical practice. Given their potential to stimulate both adaptive and innate antitumor immune responses, dendritic cells (DCs) have come under intense scrutiny in recent years as pharmacological tools for cancer immunotherapy. Conceptually, the clinical effectiveness of this form of active immunotherapy relies on the completion of three critical steps: 1) the DCs used as immunotherapeutic vehicles must properly activate the antitumor immune effector cells of the host, 2) these immune effector cells must be receptive to stimulation by the DCs and be competent to mediate their antitumor effects, which 3) requires overcoming the various immune-inhibitory mechanisms used by the tumor cells. In this review, following a brief overview of the pivotal milestones in the history of cancer immunotherapy, we will introduce the reader to the basic immunobiological and pharmacological principles of active cancer immunotherapy using DCs. We will then discuss how current research is trying to define the optimal parameters for each of the above steps to realize the full clinical potential of DC therapeutics. Given its high suitability for immune interventions, acute myeloid leukemia was chosen here to showcase the latest research trends driving the field of DC-based cancer immunotherapy.
What Financial and Non-Financial Information on Intangibles is Value Relevant? A Review of the Evidence

This paper evaluates what we have learned about the relevance and reliability of financial and non-financial information on intangibles from the value relevance literature. Because value relevance studies do not easily allow judgements about the reliability of information on intangibles, and this is an issue of central interest, this paper takes a rather wide look across a range of literatures to try to piece together some indirect evidence on both relevance and reliability. The evidence from a package of value relevance and triangulation studies suggests RD and the possibility that giving management discretion, with regulatory guidance, to report intangibles might facilitate more value relevant information on intangibles.
Learning and Incentive: A Study on Analyst Response to Pension Underfunding

There is a long-standing debate on whether sell-side analysts learn from their experience to improve earnings forecast skills. This study shows that incentive is an important factor for understanding the “learning by doing” effect by analysts. We examine analysts’ response to a complex type of information – corporate pension underfunding. Pension underfunding negatively impacts future earnings and analysts on average underreact to such information in their earnings forecasts. More importantly, when there is a strong incentive for analysts to deliver accurate forecasts, analyst learning effectively reduces their underreaction to pension underfunding information. On the other hand, when such an incentive is absent, the analyst learning effect is not discernible in the data. Further evidence suggests that analyst learning and incentive jointly reduce stock market mispricing associated with corporate pension underfunding.
CYP2A6 polymorphisms in Malays, Chinese and Indians

The genetically polymorphic cytochrome P450 (CYP) 2A6 is the major nicotine-oxidase in humans that may contribute to nicotine dependence and cancer susceptibility. The authors investigated the types and frequencies of CYP2A6 alleles in the three major ethnic groups in Malaysia and CYP2A6*1A, CYP2A6*1B, CYP2A6*1x2, CYP2A6*2, CYP2A6*3, CYP2A6*4, CYP2A6*5, CYP2A6*7, CYP2A6*8 and CYP2A6*10 were determined by allele-specific polymerase chain reaction (PCR) in 270 Malays, 172 Chinese and 174 Indians. Except for CYP2A6*2 and *3 that were not detected in the Malays and Chinese, all the other alleles were detected. Frequencies for the CYP2A6*4 allele were 7, 5 and 2%, respectively, in Malays, Chinese and Indians. A statistically significant high frequency of the duplicated CYP2A6*1x2 allele occurred among Chinese. Among Malays and Chinese, the most common allele was CYP2A6*1B, but it was CYP2A6*1A among Indians. These ethnic difference in frequencies suggested that further studies are required to investigate the implications on diseases such as cancer and smoking behaviour among these major ethnic groups in Malaysia.
A Theory of Channel Price Promotions

Manufacturers can stimulate sales by a temporary wholesale price reduction for the retailer, a rebate directed toward consumers, or a combination of both. The trade-offs between these price promotions are analyzed, providing insights about their roles, profitability, and welfare properties. Retailers' rebates are also studied. While price discrimination is a common explanation for rebates to consumers, when a product is sold through a distribution channel, the manufacturer may also use rebates to motivate retail participation in the promotion. This explains why rebates may be offered even when all consumers use them and price discrimination does not occur. Copyright 1991 by American Economic Association.
Young teenagers and older sexual partners: correlates and consequences for males and females.

CONTEXT Limited nationally representative information exists on the characteristics of teenagers who had first sex at an early age with an older partner. METHODS Gender-specific analyses were conducted of 2002 National Survey of Family Growth data from 1,838 females and 1,426 males aged 18-24. Multivariate analyses examined the associations between family and individual characteristics and having a first sexual experience before age 16 with an older partner, and between age and partners' age difference at first sex and contraceptive use and having or fathering a child as a teenager. RESULTS Sex at a young age with an older partner was associated with not living with a biological parent at age 14 and Hispanic ethnicity for females and males, early menarche and religious attendance for females, and black race for males. Among females and males, first sex by age 16 was negatively associated with contraceptive use at first sex (odds ratios, 0.7 for each) and positively associated with a teenage birth (1.6 and 2.9, respectively); having an older first partner was associated with poor reproductive health outcomes among females. Among females, the combination of young age and an older partner at first sex was positively associated with having a teenage birth. Among males, sex before age 16 with an older partner was associated with more than twice the odds of fathering a child as a teenager compared with the odds among those who had first sex at age 16-17. CONCLUSIONS Interventions should target specific teenage populations, including males, to dissuade them from having sex at a young age and with older partners. Also, prevention efforts should target potential older teenage partners and adult partners of young teenagers.
Social Aggregation Without the Expected Utility Hypothesis

This paper investigates the possibilities for satisfaction of both the ex-ante and ex-post Pareto principles in a general model in which neither individual nor social preferences necessarily satisfy the Expected Utility Hypothesis. If probabilities are subjective and allowed to vary, three different impossibility results are presented. If probabilities are 'objective' (identical across individuals and the observer), necessary and sufficient conditions on individual and social value functions are found (Theorem 4). The resulting individual value functions are consistent not only with Subjective Expected Utility theory, but also with some versions of Prospect Theory, Subjectively Weighted Utility Theory, and Anticipated Utility Theory. Social Preferences are Weighted Generalized Utilitarian and, in the case in which individual preferences satisfy the Generalized Bernoulli Hypothesis, they are Weighted Utilitarian. The objective-probability results for social preferences cast a new light on Harsanyi's Social Aggregation Theorem, which assumes that both individual and social preferences satisfy the Expecte Utility Hypothesis.
Investigation of relation between visceral and subcutaneous abdominal fat volumes and calcified aortic plaques via multislice computed tomography

Objective The present study investigated effect of subcutaneous fat volume and abdominal visceral fat volume on aortic atherosclerosis via multislice computed tomography. Materials and methods The present study comprised 424 subjects who underwent non-contrast-enhanced abdominal CT in our clinic between June 2012 and June 2013. Using dedicated software visceral fat volume was calculated for each individual and then subcutaneous fat volume was calculated by subtracting visceral fat volume from total fat volume. By dividing visceral fat volume/subcutaneous fat volume participants were assigned to three groups according to their mean visceral fat volume/subcutaneous fat volume: Group 1 consisted of subjects with visceral fat volume/subcutaneous fat volume lower than 0.48 (Group 1 < 0.48); Group 2 consisted of subjects with visceral fat volume/subcutaneous fat volume equal to or higher than 0.48 and lower than 0.69 (0.48 ≤ Group 2 < 0.69); and Group 3 consisted of subjects with visceral fat volume/subcutaneous fat volume equal to or higher than 0.69 (Group 3 ≥ 0.69). Results The mean abdominal aortic calcium scores according to Agatston scoring (au) were 136.8 ± 418.7 au in Group 1, 179.9 ± 463 au in Group 2 and 212.2 ± 486.9 in Group 3, respectively. Conclusions We have demonstrated a significant correlation between visceral fat volume and abdominal aorta atherosclerosis, while there was absence of significant correlation between subcutaneous fat volume and abdominal atherosclerosis.
MRI using piecewise‐linear spiral trajectory

A new generation of high power gradient systems which allow much faster MR imaging as well as shorter echo times has recently become available. Some of these high‐speed gradient systems impose limits on the percentage of time during which the gradient can change in amplitude (slewing duty cycle). While this limitation may be immaterial to many 2DFT and echo planar imaging methods, a traditional circular spiral trajectory is difficult to use on these systems because its gradient waveforms change during the entire course of the trajectory so that the slewing duty cycle during the readout period is 100%. We describe a piecewise‐linear spiral trajectory which is composed of linear segments and rounded corners. This trajectory reduces the slewing duty cycle while maintaining the desirable imaging properties of circular spirals including interleaving by simple gradient rotation. For one representative example, the slewing duty cycle is reduced to 46%. A conventional gridding method was used for image reconstruction, but a new numerical algorithm to calculate the density compensation factor was required. Use of piecewise‐linear spiral trajectories reduces the impact imposed by limited gradient slewing duty cycle.
Food Insecurity and Health Care Utilization Among Older Adults in the United States

ABSTRACT This study examined the relationships between food insecurity and utilization of four health services among older Americans: office visits, inpatient hospital nights, emergency department visits, and home health care. Nationally representative data from the 2011 and 2012 National Health Interview Survey were used (N = 13,589). Nearly 83.0% of the sample had two or more office visits, 17.0% reported at least one hospital night, 23.0% had at least one emergency room visit, and 8.1% used home health care during the past 12 months. Adjusting for confounders, food-insecure older adults had higher odds of using more office visits, inpatient hospital nights, and emergency department visits than food-secure older adults, but similar odds of home health care utilization. The findings of this study suggest that programs and policies aimed at reducing food insecurity among older adults may have a potential to reduce utilization of health care services.
