The Internationalization of Firms and Markets: Its Significance and Institutional Structuring

The growing interdependence of the industrialized economies as a result of increasing foreign direct investment by transnational companies has been seen as leading to fundamental changes in the world economy. Three aspects of such changes can be identified: the establishment of a distinct global system of coordination and competition, the denationalization of leading firms and the international standardization of managerial structures and practices. These changes depend, however, on the development of distinct and powerful supra-national institutions and the limited cohesion and variety of national institutions. As long as national political, financial, labour and cultural systems remain quite different and integrated, and at least as powerful as international ones, the postwar internationalization of firms and markets is limited in degree and significance.
Early experiences and attachment relationships of Greek infants raised in residential group care.

BACKGROUND The attachment relationships of infants reared in residential group care from birth, and links between attachment quality and psychosocial development and caregiver sensitivity were studied, with 86 infants reared in group care and 41 infants reared in their own two-parent families who attended day-care centres. METHODS Attachment, cognitive development, temperament, and observed social behaviour of the two groups were studied, as was the quality of care by caregivers and mothers. RESULTS Sixty-six per cent of infants reared in residential group care showed disorganised attachment to their caregivers, compared with 25% of control infants; 24% of group care infants were securely attached, compared with 41% of control infants. The two groups differed in cognitive development, in temperament and observed social behaviour. Within the residential group care babies, those that were securely attached were observed to express more frequent positive affect and social behaviour, and to initiate more frequent interaction with their caregivers. CONCLUSIONS Residential care affected all aspects of the infants' development and was linked to a high rate of disorganised attachment.
Docetaxel, cisplatin, and fluorouracil induction chemotherapy followed by accelerated fractionation/concomitant boost radiation and concurrent cisplatin in patients with advanced squamous cell head and neck cancer: A Southwest Oncology Group phase II trial (S0216)

In an effort to optimize nonoperative therapy in patients with locoregionally advanced head and neck squamous cell cancer, the Southwest Oncology Group conducted a phase II trial combining 3‐drug taxane‐containing induction chemotherapy with accelerated fractionation/concomitant boost radiation and concomitant single‐agent cisplatin.
Hemorheological follow‐up after splenectomy and spleen autotransplantation in mice

We previously reported on a spleen autotransplantation model in mice, with spleen function studies at 6 weeks. The present study was undertaken to investigate long‐term hemorheological functions. A/J and BALB/c inbred mice were divided into four groups: control, sham surgery (SH), splenectomy (SE), and spleen autotransplantation (AU). Hematological and hemorheological parameters were determined. Leukocyte counts in the SE and AU groups were significantly higher than in controls, while hematocrit levels were markedly lower. Mean erythrocyte volume did not change significantly. Platelet counts in the AU group were significantly lower, and red blood cell deformability was significantly worse in the SE group. The AU group also had increased cell transit time, but it was less than that in the SE group. The SE group showed the highest fibrinogen levels. We conclude that there are some consistent differences in hematological parameters between splenectomy and spleen autotransplantation. These data suggest that spleen autotransplantation may partially restore hemorheological functions following splenectomy. © 2006 Wiley‐Liss, Inc. Microsurgery 26: 38–42, 2006.
Market Power and Reputational Concerns in the Ratings Industry

This paper studies the incentives of rating agencies to reveal the information that they obtain about their client firms. In the model, rating agencies seek to maximize their reputation and protect their market power. They observe public information and obtain either precise or noisy private information about a firm. Reputational concerns dictate that a rating reflects private information when it is precise. However, when private information is noisy, two situations arise. In a monopoly, the rating agency may ignore private information and issue a rating that conforms to public information. Under some conditions, it may even become cautious and issue bad ratings ignoring both types of information. With competition, however, it has incentives to contradict public information as a way to pretend that it holds precise private information. Moreover, it may become more likely to issue good ratings in an attempt to protect market power.
Inflation Illusion, Credit, and Asset Pricing

This paper considers asset pricing in a general equilibrium model in which some, but not all, agents suffer from inflation illusion. Illusionary investors mistake changes in nominal interest rates for changes in real rates, while smart investors understand the Fisher equation. The presence of smart investors ensures that the equilibrium nominal interest rate moves with expected inflation. The model also predicts a nonmonotonic relationship between the price-to-rent ratio on housing and nominal interest rates -- housing booms occur both when the nominal rate is especially low and when it is especially high. In either situation, disagreement about real interest rates between smart and illusionary investors stimulates borrowing and lending and drives up the price of collateral. The resulting housing boom is stronger if credit markets are more developed. We document that many countries experienced a housing boom in the high-inflation 1970s and a second, stronger, boom in the low-inflation 2000s.
Dynamics in the Specification of Tourism Demand Models

The specification of a tourism demand model now commonly includes lagged demand as an explanatory variable. This raises issues in the formulation and interpretation of econometric tourism demand models. It is argued that a simple lagged demand term is not sufficient to account for the dynamics of tourism demand. Many alternative specifications of the dynamic elements and form have been used in tourism demand modelling. This paper helps to resolve the issue of how the dynamics should be specified. It does this by a thorough review of the dynamic elements relevant to tourism demand and by demonstrating that the specification does make a difference in practice. Consideration of different formulations of the dynamics of tourism demand, drawing on theory and specific characteristics of tourism, leads to the recommendation of an ARIMA with explanatory variables model form.
Autonomous marine hyperspectral radiometers for determining solar irradiances and aerosol optical properties

Abstract. We have developed two hyperspectral radiometer systems which require no moving parts, shade rings or motorised tracking, making them ideally suited for autonomous use in the inhospitable remote marine environment. Both systems are able to measure direct and diffuse hyperspectral irradiance in the wavelength range 350–1050 nm at 6 nm (Spectrometer 1) or 3.5 nm (Spectrometer 2) resolution. Marine field trials along a 100° transect (between 50° N and 50° S) of the Atlantic Ocean resulted in close agreement with existing commercially available instruments in measuring (1) photosynthetically available radiation (PAR), with both spectrometers giving regression slopes close to unity (Spectrometer 1: 0.960; Spectrometer 2: 1.006) and R2 ∼ 0.96; (2) irradiant energy, with R2 ∼ 0.98 and a regression slope of 0.75 which can be accounted for by the difference in wavelength integration range; and (3) hyperspectral irradiance where the agreement on average was between 2 and 5 %. Two long duration land-based field campaigns of up to 18 months allowed both spectrometers to be well calibrated. This was also invaluable for empirically correcting for the wider field of view (FOV) of the spectrometers in comparison with the current generation of sun photometers ( ∼ 7.5° compared with ∼ 1°). The need for this correction was also confirmed and independently quantified by atmospheric radiative transfer modelling and found to be a function of aerosol optical depth (AOD) and solar zenith angle. Once Spectrometer 2 was well calibrated and the FOV effect corrected for, the RMSE in retrievals of AOD when compared with a CIMEL sun photometer were reduced to ∼ 0.02–0.03 with R2 > 0.95 at wavelengths 440, 500, 670 and 870 nm. Corrections for the FOV as well as ship motion were applied to the data from the marine field trials. This resulted in AOD500 nm ranging between 0.05 in the clear background marine aerosol regions and ∼ 0.5 within the Saharan dust plume. The RMSE between the handheld Microtops sun photometer and Spectrometer 2 was between 0.047 and 0.057 with R2 > 0.94.
How Types of Goods and Property Rights Jointly Affect Collective Action

The study of collective action has matured dramatically since Mancur Olson challenged scholars by positing a general theory in his pathbreaking book on The Logic of Collective Action (1965). Olson's theoretical predictions related to the incapacity of individuals, except under limited conditions, to solve on their own what are now known as `collective action problems'. Olson argued that one characteristic of goods - that of exclusion - defined all public goods. In contemporary analysis, the problem of achieving exclusion of noncontributors has come instead to characterize all types of collective action problems. Multiple subtypes of collective action problems have been identified. One major class of collective action problems are referred to in contemporary literature as public goods. Another class are referred to as common-pool resources. Common-pool resources are characterized by difficulty of exclusion and subtractability of resource units and are threatened by overuse leading to congestion or even destruction of the resource. Such threats do not apply to public goods. Diverse production and allocation functions generate further important differences in behavior and outcomes. Scholars have also begun to recognize multiple types of property right bundles that distinguish among authorized entrants, users and claimants, proprietors and full owners. Empirical studies show that groups of individuals who possess at least the rights of proprietorship are able to govern and manage their systems more effectively than presumed in the earlier theoretical literature. The article ends with an analysis of the factors that may be conducive to the organization of a common-property regime as contrasted to a private-property regime.
CD206‐positive myeloid cells bind galectin‐9 and promote a tumor‐supportive microenvironment

In patients with metastatic melanoma, high blood levels of galectin‐9 are correlated with worse overall survival and a bias towards a Th2 inflammatory state supportive of tumor growth. Although galectin‐9 signaling through TIM3 on T cells has been described, less is known about the interaction of galectin‐9 with macrophages. We aimed to determine whether galectin‐9 is a binding partner of CD206 on macrophages and whether the result of this interaction is tumor‐supportive. It was determined that incubation of CD68+ macrophages with galectin‐9 or anti‐CD206 blocked target binding and that both CD206 and galectin‐9 were detected by immunoprecipitation of cell lysates. CD206 and galectin‐9 had a binding affinity of 2.8 × 10−7 m. Galectin‐9 causes CD206+ macrophages to make significantly more FGF2 and monocyte chemoattractant protein (MCP‐1), but less macrophage‐derived chemokine (MDC). Galectin‐9 had no effect on classical monocyte subsets, but caused expansion of the non‐classical populations. Lastly, there was a positive correlation between increasing numbers of CD206 macrophages and galectin‐9 expression in tumors, and high levels of CD206 macrophages correlated negatively with melanoma survival. These results indicate that galectin‐9 binds to CD206 on M2 macrophages, which appear to drive angiogenesis and the production of chemokines that support tumor growth and poor patient prognoses. Targeting this interaction systemically through circulating monocytes may therefore be a novel way to improve local anti‐tumor effects by macrophages.

Association of Blood Pressure With Short- and Long-Term Functional Outcome After Stroke Thrombectomy: Post Hoc Analysis of the SIESTA Trial

Background and Purpose— Outcome after mechanical thrombectomy for ischemic stroke may be influenced by blood pressure (BP). This study aims to assess the association of BP changes during general anesthesia versus conscious sedation with functional outcome after mechanical thrombectomy. Methods— SIESTA (Sedation vs Intubation for Endovascular Stroke Treatment) was a monocentric randomized trial of general anesthesia versus conscious sedation during mechanical thrombectomy involving BP target protocols. In this post hoc analysis, BP measurements were divided into 4 phases: preintervention, prerecanalization, postrecanalization, and postintervention. We examined the association between BP and functional outcomes (defined by improvement of 24-hour National Institutes of Health Stroke Scale [NIHSS] and 3-month modified Rankin Scale). Results— We found no association between the difference in systolic BP, diastolic BP, and mean arterial pressure from baseline to the different phases of intervention and NIHSS change after 24 hours. Only baseline diastolic BP was associated with a reduced improvement in NIHSS (&bgr;=0.17, P<0.01). There was no association of BP drops with a change in modified Rankin Scale at 3 months. About sedation, only baseline mean arterial pressure preintervention revealed significant associations (&bgr;=0.16, P<0.01) with less change in 24-hour NIHSS in conscious sedation group. Otherwise, there was no association for differences of any of the BP measurements with a change in 24-hour NIHSS and long-term functional outcome either in general anesthesia or the conscious sedation group when analyzed separately, consistent with our findings in the entire cohort. Doses of propofol (&bgr;=0.84, P=0.04) and norepinephrine (&bgr;=1.87, P=0.01) administered during intervention before recanalization were associated with reduced improvement of NIHSS at 24 hours. Conclusions— In a setting, where both sedation regimes general anesthesia and conscious sedation were performed according to strict protocols directed at avoiding BP extremes, our findings suggest that peri-interventional BP drops were not associated with either early neurological improvement or long-term functional outcome.

Learning, Pricing, Timing and Hedging of the Option to Invest for Perpetual Cash Flows with Idiosyncratic Risk

The paper considers the option of an investor to invest in a project that generates perpetual cash flows, of which the drift parameter is unobservable. The investor invests in a liquid financial market to partially hedge cash flow risk and estimation risk. We derive two 3-dimensional non-linear free-boundary PDEs satisfied by the utility-based prices of the option and cash flows. We provide an approach to measure the information value. A numerical procedure is developed. We show that investors have not only idiosyncratic-risk-induced but also estimation-risk-induced precautionary saving demands. A growth of estimation risk, risk aversion or project risk delays investment, but it is accelerated if the project is more closely correlated with the market. Partial information results in a considerable loss, which reaches the peak value at the exercising time and increases with project risk and estimation risk. The more risk-averse the investor or the weaker the correlation, the larger the loss.
The English Language Fluency and Earnings of Ethnic Minorities in Britain

This study addresses two issues. First it estimates how much of the male and female ethnic earnings gap is the result of an advantage in the English language and whether there is an earnings penalty to non-whites, over and above this. Lack of fluency is shown to have a highly significant impact on the earnings of ethnic minorities in Britain, although the language penalty is much greater for women than it is for men. Moreover, only foreign born non-white males that have arrived in Britain between 1970 and 1994, exhibit lower earnings once language fluency is taken into consideration, whilst British born females exhibit higher earnings. So the evidence here suggests that non-white earnings are assimilating towards those of whites and that lower female non-white earnings are a direct result of a lack of fluency rather than ethnicity. Secondly, the study will try to measure any endogenous bias associated with the non-fluency earnings penalty. Controlling for the endogeneity between language fluency and earnings is shown to be problematic. Estimates suggest that single equation earnings functions slightly underestimate the true language fluency penalty for males, and slightly overestimate the fluency penalty for females. Finally, education and fluency are not surprisingly shown to be complementary.
Age-Related Interference between the Selection of Input-Output Modality Mappings and Postural Control—a Pilot Study

Age-related decline in executive functions and postural control due to degenerative processes in the central nervous system have been related to increased fall-risk in old age. Many studies have shown cognitive-postural dual-task interference in old adults, but research on the role of specific executive functions in this context has just begun. In this study, we addressed the question whether postural control is impaired depending on the coordination of concurrent response-selection processes related to the compatibility of input and output modality mappings as compared to impairments related to working-memory load in the comparison of cognitive dual and single tasks. Specifically, we measured total center of pressure (CoP) displacements in healthy female participants aged 19–30 and 66–84 years while they performed different versions of a spatial one-back working memory task during semi-tandem stance on an unstable surface (i.e., balance pad) while standing on a force plate. The specific working-memory tasks comprised: (i) modality compatible single tasks (i.e., visual-manual or auditory-vocal tasks), (ii) modality compatible dual tasks (i.e., visual-manual and auditory-vocal tasks), (iii) modality incompatible single tasks (i.e., visual-vocal or auditory-manual tasks), and (iv) modality incompatible dual tasks (i.e., visual-vocal and auditory-manual tasks). In addition, participants performed the same tasks while sitting. As expected from previous research, old adults showed generally impaired performance under high working-memory load (i.e., dual vs. single one-back task). In addition, modality compatibility affected one-back performance in dual-task but not in single-task conditions with strikingly pronounced impairments in old adults. Notably, the modality incompatible dual task also resulted in a selective increase in total CoP displacements compared to the modality compatible dual task in the old but not in the young participants. These results suggest that in addition to effects of working-memory load, processes related to simultaneously overcoming special linkages between input- and output modalities interfere with postural control in old but not in young female adults. Our preliminary data provide further evidence for the involvement of cognitive control processes in postural tasks.
The relationship between respiration phase and reaction time.

The relationship between phase of normal respiration and reaction time (RT) was studied. Ss were required to respond by pressing a switch each time a simple auditory signal was presented. Averages of response times were calculated for signals occurring during each of three identifiable phases of normal respiration. It was found that mean RT for signals presented during the inhalation phase of respiration was significantly less than for signals presented during either the exhalation phase or the pause between exhalation and inhalation.
American Depositary : A Case Study for Brazilian Market

Specialists often question market efficiency. Some works suggest arbitrage opportunities in several financial operations. Such opportunities can be explained mainly by information asymmetry, since pricing in the stock market is directly linked to information; therefore, the investor that has access to such information the soonest has a competitive advantage. The objective of this paper is to verify the existence of arbitrage opportunities via ADRs, traded in the American market, and their respective stocks, which are traded in the domestic market. Through a case study conducted with four companies, not considering the transition costs, arbitrage opportunity windows were found. Among the companies studied, two had frequent arbitrage opportunities, for one of them the arbitrage opportunity can be shaped by the time series model.
The Beta Anomaly in the Japanese Equity Market and Investor Behavior

It is well known that high-beta stocks are associated with a low alpha relative to the capital asset pricing model and to the Fama–French three-factor model. We show that the beta anomaly in the Japanese market is attributable to foreign institutional investors, not domestic individuals. Foreigners overweight high-beta stocks; the anomaly weakens or reverses when their investment increases and strengthens when it decreases; and they invest more in high-beta than low-beta stocks when increasing investment and sell high-beta more than low-beta stocks when reducing it. We do not find analogous results for individual investors. Our results suggest that the beta anomaly reflects a preference for high-beta securities by institutional investors aiming to beat a benchmark.
