U.S. Capitalism: A Tarnished Model?

Executive Overview The apparent success of the U.S. model of capitalism as it developed in the 1990s and early 21st century encouraged many business and policy elites to regard it as an ideal form that should be adopted by other countries and regions. The recent collapse of the U.S. financial system and the current recession are, however, likely to limit the attractiveness of this U.S. model in both OECD1 countries and industrializing economies. In this article, I review the key features and limitations of the postwar U.S. economic model as well as the challenges to this model from the success of many Japanese firms doing business in the U.S. market and the rapid rise of the Asian “tigers. ” Given the current situation, it is likely that the influence of the fully fledged market fundamentalist model, imposed on many Eastern European countries in the early 1990s, will be greatly diminished, and attention focused much more on alternative forms of capitalism. Most of these involve the state taking a more proa.
A study of the non‐economic determinants in tourism demand

Traditionally, many studies have attempted to use economic demand models. This paper stresses on the influence of non-economic factors on tourism demand. Some researchers have suggested that tourists from different origins have various cultural and nationalistic backgrounds, and they may interpret visual imagery and experiences differently. Aligning with this suggestion, we have investigated different underlying factors of tourism demand from four continents (Asia, the Americas, Europe and Oceania). Statistical data are collected from international organisations and 135 countries were covered. Our results showed that there are differences and similarities among the factors in determining the tourism demand. Copyright © 2009 John Wiley & Sons, Ltd.
The Size and Structure of the World Mutual Fund Industry

This paper analyses the mutual fund industry for 20 countries using a new database of more than 50,000 mutual funds. The results suggest that more developed industries provide more benefits to investors as they diversify more internationally, charge lower annual charges and present more product sophistication. The results also have important policy implications by emphasising the role of competition and contestability in industry development. Fewer barriers to entry are positively associated with a larger industry, and concomitantly with more efficiency in terms of returns and fees.
Futures Manipulation with "Cash Settlement"

This paper investigates the susceptibility of futures markets to price manipulation in a two-period model with asymmetric information and "cash settlement" futures contracts. Without "physical delivery," strategies based on "corners" or "squeezes" are infeasible. However, uninformed investors still earn positive expected profits by establishing a futures position and then trading in the spot market to manipulate the spot price used to compute the cash settlement at delivery. The authors also show that as the number of manipulators grows, profits from manipulation fall to zero. However, even in the limit, manipulation still has a nontrivial impact on market liquidity. More broadly, they interpret manipulation as a form of endogenous "noise trading" which can arise in multiperiod security markets. Copyright 1992 by American Finance Association.
Is Wheat a Homogeneous Product

A hedonic approach is used to test for two kinds of product differentiation for wheat. It is shown that wheat is differentiated by end use and by country of origin. This simply recognizes the fact that buyers purchasing wheat for different purposes put different weights on quality criteria and that country-specific factors such as weather as well as grading and inspection systems matter. The results suggest that between 1980 and 1988, wheat protein content had a significant influence on price. This influence varies over time and across wheat categories.
Lexicographic Refinements in Possibilistic Decision Trees

Possibilistic decision theory has been proposed twenty years ago and has had several extensions since then. Because of the lack of decision power of possibilistic decision theory, several refinements have then been proposed. Unfortunately, these refinements do not allow to circumvent the difficulty when the decision problem is sequential. In this article, we propose to extend lexicographic refinements to possibilistic decision trees. We show, in particular, that they still benefit from an Expected Utility (EU) grounding. We also provide qualitative dynamic programming algorithms to compute lexicographic optimal strategies. The paper is completed with an experimental study that shows the feasibility and the interest of the approach.
Hexadecane mineralization in oxygen-controlled sediment-seawater cultivations with autochthonous microorganisms

Laboratory studies investigated the influence of dissolved oxygen tension (DOT) on microbial degradation of hexadecane in cultures with sediment-seawater suspensions. With a fermentor system, it was possible to adjust and regulate different oxic conditions (DOTs between 0.4 and 80% of oxygen saturation) as well as anoxia. The effects of DOT reduction on the amount and rate of hexadecane degraded and on the degree of mineralization and on the production of biomass were investigated. When the DOT was reduced from 80% to 5%, no dependence of the investigated parameters on the oxygen concentration was found. The amount of hexadecane degraded was constant, with an average value of 86% of the initially applied amount. The degradation rate was constant even down to 1% DOT, with an average value of 0.15 mg of hexadecane per g of sediment per h (16.2 mg liter-1 h-1). The mean degree of mineralization was 70% of the initially applied hexadecane, and biomass production reached a value of about 1.5 g per g of hexadecane consumed. A significant influence on the degradation process was detected only with DOTs below 1%. The degree of mineralization and the amount of degraded hexadecane decreased, whereas the degradation rate was still unaffected. Under anoxic conditions, no hexadecane degradation occurred within 190 h. The fact that the hexadecane biodegradation rate was constant down to at least 0.04% DOT shows that the actual oxygen concentration is of minor importance as long as the oxygen supply is high enough to guarantee the oxygen-dependent degradation step.
The role of component-wise boosting for regional economic forecasting

This paper applies component-wise boosting to the topic of regional economic forecasting. By using unique quarterly gross domestic product data for one German state for the period from 1996 to 2013, in combination with a large data set of 253 monthly indicators, we show how accurate forecasts obtained from component-wise boosting are compared to a simple benchmark model. We additionally take a closer look into the algorithm and evaluate whether a stable pattern of selected indicators exists over time and four different forecasting horizons. All in all, boosting is a viable method for forecasting regional GDP, especially one and two quarters ahead. We also find that regional survey results, indicators that mirror the Saxon economy and the Composite Leading Indicators by the OECD, get frequently selected by the algorithm.
Toppling Jefferson's Wall or Tiptoeing Around it?

Through interviews with coordinators of faith-based mentoring programs, a statewide study examined publicly funded efforts to widen the involvement of religious groups in welfare service provision. Analysis focused on front-line implementers' ability to function as boundary spanners in a complex, unsettled environment. The study identified three salient factors affecting implementation in this new faith-friendly arena: the employment background of the programcoordinators, the rural or urban setting of the program, and the limitations of a constrained state welfare apparatus. The experiences of these so-called early adopters of charitable choice indicate the scope, strength, and surmountability of institutional barriers confronting implementers.
Pattern of muscle fiber type formation in the pig

The aim of this study was to analyze the temporal sequence of expression of the myosin isoforms in the populations of muscle fibers in the pig and to bring more information on the origin of the strikingly different pattern of fiber composition and distribution between the deep medial red (oxido‐glycolytic) and superficial white (glycolytic) portions of semitendinosus (ST) muscle. Muscle samples were taken from 49‐, 55‐, 75‐, 90‐, 103‐, and 113‐ (birth) day‐old fetuses, from 6‐, 11‐, 21‐, 35‐, 50‐, and 80‐day‐old piglets, and from a 3‐year‐old pig. Our results confirm the sequential formation of primary and secondary generation fibers. The use of immunohistochemistry and heterologous monoclonal antibodies (mAb) directed against specific myosin heavy chain (MHC) isoforms revealed a different pattern of gene expression between the two portions of the ST muscle for both generations of fibers. By 75 days of gestation (dg), primary myotubes from the deep medial portion stained positively for the anti‐slow MHC mAb and negatively for the adult anti‐fast MHC, whereas the opposite was observed in the superficial portion. Secondary fibers never expressed slow MHC until late gestation. Instead, they expressed an adult fast MHC isoform as soon as they formed in the deep medial portion and later on in the superficial portion. From late gestation to the first 3 postnatal weeks, slow MHC began to be expressed in a subpopulation of secondary fibers. These fibers were in the direct vicinity of primary myotubes in the deep medial portion, whereas their location could not be established in the superficial portion. The remaining secondary fibers matured to type IIA in the direct vicinity of these type I fibers and to type IIB at the periphery of the islets. In both portions of the muscle, a subpopulation of secondary fibers, the first ones to express slow MHC, also transitorily expressed a MHC that was identical or closely related to the αcardiac MHC during the early postnatal period. A third generation of small diameter fibers was observed shortly after birth and reacted with the anti‐fetal MHC mAb; their destiny remains to be established. The present work reveals a remarkable pattern of MHC gene expression in the pig and raises many questions on the real nature of these isoforms. In order to answer these questions, we have undertaken to make a cDNA library of pig skeletal muscle and to screen this library with the same mAbs used in the present study. ©1995 Wiley‐Liss, Inc.
The Theory of Finance

This module presents the fundamental concepts of modern finance theory. This will form the foundation for other modules in finance and is primarily designed for finance students. This material is reinforced by the specialist (Group A) finance options available in the spring term. Although this module is open to economics students, our experience is that they find this difficult without the support of the specialist modules and only the best economics students do well. Much of modern finance is technically demanding as it makes considerable use of mathematics. This is particularly true of derivatives and option pricing, an area central to modern finance that employs stochastic calculus instead of ordinary calculus.
Energy Intensity of Agriculture and Food Systems

The relationships between energy use in food systems, food system productivity, and energy resource constraints are complex. Moreover, ongoing changes in food production and consumption norms concurrent with urbanization, globalization, and demographic changes underscore the importance of energy use in food systems as a food security concern. Here, we review the current state of knowledge with respect to the energy intensity of agriculture and food systems. We highlight key drivers and trends in food system energy use along with opportunities for and constraints on improved efficiencies. In particular, we point toward a current dearth of research with respect to the energy performance of food systems in developing countries and provide a cautionary note vis-a-vis increasing food system energy dependencies in the light of energy price volatility and concerns as to long-term fossil energy availabilities.
An empirical evaluation of accounting income numbers

Accounting theorists have generally evaluated the usefulness of accounting practices by the extent of their agreement with a particular analytic model. The model may consist of only a few assertions or it may be a rigorously developed argument. In each case, the method of evaluation has been to compare existing practices with the more preferable practices implied by the model or with some standard which the model implies all practices should possess. The shortcoming of this method is that it ignores a significant source of knowledge of the world, namely, the extent to which the predictions of the model conform to observed behavior. It is not enough to defend an analytical inquiry on the basis that its assumptions are empirically supportable, for how is one to know that a theory embraces all of the relevant supportable assumptions? And how does one explain the predictive powers of propositions which are based on unverifiable assumptions such as the maximization of utility functions? Further, how is one to resolve differences between propositions which arise from considering different aspects of the world? The limitations of a completely analytical approach to usefulness are illustrated by the argument that income numbers cannot be defined substantively, that they lack "meaning" and are therefore of doubtful utility. ' The argument stems in part from the patchwork development of account-
Soybean Plant Stage and Population Growth of Soybean Aphid

Abstract The soybean aphid, Aphis glycines Matsumura, is a newly invasive species of aphid in North America. Previous studies disagree as to whether soybean, Glycine max (L.) Merr. , plant stage has an impact on aphid intrinsic rate of increase. Therefore, the growth rate of soybean aphids on soybean plants of different stages was examined at two different scales in the field. A planting date experiment was used to measure the population growth of soybean aphids on plants of different stages. Clip-cages were used to measure life history characteristics of individual aphids on plants of different stages. No differences were found in the population growth or dynamics of soybean aphids in the planting date experiment. The life history characteristics of individual aphids also showed no significant difference when feeding on different growth stages of soybean plants. The impact of these findings on soybean aphid management is discussed and the possible reasons why the results differ from previous estimates of the aphid growth–plant stage relationship are considered.
Teaching approaches in enterprise education: a classroom observation study

Abstract This paper outlines research which was conducted into teaching approaches in the context of enterprise lessons. The teaching resource material and associated literature supporting enterprise education in schools strongly suggested that the teaching approaches adopted during mini‐enterprise were student‐centred. There was, however, an absence of research evidence to support or refute this assertion. This research represents an initial investigation into the teaching approaches adopted by teachers in enterprise classrooms. The purpose of the investigation was to ascertain the extent to which teachers were engaging in more student‐centred practices in enterprise lesson in comparison with their non‐enterprise lessons. Teachers were observed over a period of a year using a specially designed observation schedule which was used to record specific teacher‐pupil interactions. Details of the design and use of the enterprise teaching observation schedule (ETOS) are provided in the paper along with the majo.
Selection Benefits of Stock-Based Compensation for the Rank-and-File

ABSTRACT: We investigate a potential selection benefit of stock-based compensation for rank-and-file employees, whose pay under this compensation form is insensitive to their individual efforts. We use a laboratory experiment to demonstrate that individuals with higher levels of dispositional optimism are more likely to choose compensation that is contingent on a company's future stock price than to choose fixed pay, even after controlling for the individual's risk preferences. Furthermore, compared to participants selecting fixed pay, those selecting stock-based compensation also perform better on a challenging problem-solving task, a result that we show is due to their higher levels of dispositional optimism. Collectively, we demonstrate that stock-based compensation can have productivity-enhancing effects, even if stock prices are completely insensitive to individual efforts. In doing so, we provide a partial explanation for the puzzling prevalence of stock-based compensation plans at the rank-and-file.
Spondyloarthropathies in sub-Saharan Africa

HLA-B27 is virtually absent in most of the sub-Saharan Africa populations, and ankylosing spondylitis is rare; only a few patients have been reported from central and southern Africa. HLA-B27 was present in only one of 17 patients (6%). The disease shows clinical features that are similar to those observed in white HLA-B27-negative patients with ankylosing spondylitis;ie, the disease onset is later compared with HLA-B27-positive patients, the patients rarely get acute anterior uveitis as one of the extra-articular manifestations, and familial occurrence of ankylosing spondylitis is rarely observed. There is a virtual absence of ankylosing spondylitis even in the west African countries of Gambia and Senegal, where 3% to 6% of the general population has HLA-B27. The epidemic of HIV infection in sub-Saharan Africa in recent years, however, has been associated with a dramatic upsurge in the prevalence of spondyloarthropathies other than ankylosing spondylitis, primarily reactive arthritis and undifferentiated forms of the disease, and less often psoriatic arthritis. HLA-B27, because of its rarity and virtual lack of association with the observed cases of spondyloarthropathy in this population, cannot be used as an aid to diagnosis of spondyloarthropathy in black Africans. Conversely, HIV infection is increasingly showing such a strong association with reactive arthritis, psoriatic arthritis, and undifferentiated spondyloarthropathies in sub-Saharan African populations that any patient with acute or chronic inflammatory arthritis may need to be tested for possible HIV infection. More research is needed on the evaluation of risk and protective factors in sub-Saharan African populations to better delineate the relative importance of genetic and environmental factors in the pathogenesis of spondyloarthropathies.

Firms' Innovation, Public Financial Support, and Total Factor Productivity: The Case of Manufactures in Peru

Based upon an adjusted Crepon–Duguet–Mairesse (CDM) model, this paper analyzes the relationship between investment intensity, public financial support, innovation, and total factor productivity (TFP) for a sample of manufacturing firms of Peru with data obtained from the 2004 survey of science, technology, and innovation (STI) activities. The estimation of the model indicates that large firms are more likely to invest in STI activities and firms' size increases the probability of producing technological inovation (TI) and non-technological innovation (NTI). STI firms' investment intensity and public financial support have also helped manufacturing firms to increase the probability of producing TI outcomes. Further, such support may have increased firms' investment on STI activities. The innovation effects on TFP, however, were statistically not clear or robust. Thus, whereas investment intensity did increase firms' TPF in low-tech manufacturing firms, this is not the case for high-tech firms. For this group of firms, relatively high capital–labor ratio and the availability of a high level of human capital seem to promote higher levels of TFP.
Genomic Survey, Characterization, and Expression Profile Analysis of the SBP Genes in Pineapple (Ananas comosus L.)

Gene expression is regulated by transcription factors, which play many significant developmental processes. SQUAMOSA promoter-binding proteins (SBP) perform a variety of regulatory functions in leaf, flower, and fruit development, plant architecture, and sporogenesis. 16 SBP genes were identified in pineapple and were divided into four groups on basis of phylogenetic analysis. Five paralogs in pineapple for SBP genes were identified with Ka/Ks ratio varied from 0.20 for AcSBP14 and AcSBP15 to 0.36 for AcSBP6 and AcSBP16, respectively. 16 SBP genes were located on 12 chromosomes out of 25 pineapple chromosomes with highly conserved protein sequence structures. The isoionic points of SBP ranged from 6.05 to 9.57, while molecular weight varied from 22.7 to 121.9 kD. Expression profiles of SBP genes revealed that AcSBP7 and AcSBP15 (leaf), AcSBP13, AcSBP12, AcSBP8, AcSBP16, AcSBP9, and AcSBP11 (sepal), AcSBP6, AcSBP4, and AcSBP10 (stamen), AcSBP14, AcSBP1, and AcSBP5 (fruit) while the rest of genes showed low expression in studied tissues. Four genes, that is, AcSBP11, AcSBP6, AcSBP4, and AcSBP12, were highly expressed at 4°C, while AcSBP16 were upregulated at 45°C. RNA-Seq was validated through qRT-PCR for some genes. Salt stress-induced expression of two genes, that is, AcSBP7 and AcSBP14, while in drought stress, AcSBP12 and AcSBP15 were highly expressed. Our study lays a foundation for further gene function and expression studies of SBP genes in pineapple.
Does Shareholder Approval Requirement of Equity Compensation Plans Matter?

This paper studies the impact of the 2003 SEC Regulation requiring shareholder approval of all equity-based executive compensation plans on executive compensation policies and practices at S&P 500 firms. Following the 2003 Regulation, firms with shareholder approved equity plans in place or those with strong performance, while not those with non-approved plans or weak performance, increase their equity compensation proposal submission activity. The quality of equity compensation proposals improves in the after-regulation period, and shareholders exhibit greater scrutiny and monitoring of executive compensation through increased voting rights. We find a decline in the equity pay component while an increase in the cash component of total executive compensation after the 2003 Regulation and also provide evidence that the 2003 Regulation contributes to this change in compensation structure.
