The Role of FDI in Fostering Exports from the Host Country

In this paper, I propose a theoretical model analyzing the impact of FDI on exports from the host country. Using the framework of monopolistic competition with heterogenous firms, I show that the entry of highly efficient MNEs increases competition in the export market, which leads to crowding-out of domestic exporters. As a result, even though overall efficiency of the industry increases, exports by this industry may decrease.Further on, I add into my model a potential spillover effect that FDI can induce by lowering costs associated to export activities for all firms. I show that in such situation, the increased efficiency is more likely to outweigh the negative competition effect, resulting in larger exports from the host country.
ON FEATHER QUILL IMAGE DENOISING

Tiny creases of feather quill is easily disturbed by noise that causing adverse effects on recognition performance. For the shortcomings of the traditional noise reduction algorithm in the process of image, i.e., it is sensitive to the noise resulting in the problem of weakened creases characteristics, this paper discusses probability measure of noisy image on manifolds based on heat equation theory, analyses regularity and uniqueness of heat kernels on manifolds, and gets the corresponding relationship between density function of noisy data and probability density of clean data. A denoising algorithm of feather quill based on the heat equation of graph is proposed. In the method, de-noised image can be obtained through iterative solution of equation based on feather quill image representing as an undirected weighted graph. The experimental results show that this suggested method can get better effect comparing with other transform domain algorithms.
FUNDAÇÃO GETULIO VARGAS ESCOLA BRASILEIRA DE ADMINISTRAÇÃO PÚBLICA E DE EMPRESAS MESTRADO EXECUTIVO EM GESTÃO EMPRESARIAL MISSÃO ORGANIZACIONAL, UMA QUESTÃO DE DISCURSO? POR UMA ANÁLISE CRÍTICA

Through the understanding that great corporations are political, economic and social powerful agents and that their mission statements synthesize their reason of being and existing, this study aims to unveiling the political and ideological content underlying the enterprise discourse on the missions of the largest companies of Brazil. Therefore, the mission statements disclosed in the institutional and/or investor relations homepages of the 64 companies from Ibovespa, main indicator of average share prices from the Brazilian stock market, have been analyzed. The analysis were made through the appropriation of organizational culture symbolism, the critical discourse analyses, transdisciplinary theoretical instrument aiming to understand the relation between language, power, ideology and society, and from the Foucault’s discourse perspective, understanding it as an space of struggle for stabilization of the senses, which intend to be hegemonic. The data was treated in the quantitative form, searching for the most frequent words and consequently of most relevance, and in the qualitative form, grouping it in lexical categories according to their significance and its role in organizational mission statement. The results reveal the structure underlying the mission discourse, allowing the identification of specific corporative profiles according to their discursive features. Furthermore, the paper discusses how the corporative discourse appropriates the symbolic dimension with the intention of controlling and manipulating the workers, legitimize the role of corporations in society and naturalize the precepts of neoliberal ideology, presenting the current capitalist system as the only, best and inexorable form of corporate organization and production.
ESTIMATES OF DIRECT AND MATERNAL GENETIC EFFECTS FOR WEIGHTS FROM BIRTH TO 600 DAYS OF AGE IN NELORE CATTLE

Summary Estimates of direct and maternal variance and heritability for weights at each week (up to 280 days of age) and month of age (up to 600 days of age) in Zebu cattle are presented. More than one million records on 200 000 animals, weighed every 90 days from birth to 2 years of age, were available. Data were split according to week (data sets 1) or month (data sets 2) of age at recording, creating 54 and 21 data sets, respectively. The model of analysis included contemporary groups as fixed effects, and age of dam (linear and quadratic) and age of calf (linear) effects as covariables. Random effects fitted were additive direct and maternal genetic effects, and maternal permanent environmental effect. Direct heritability estimates decreased from 0.28 at birth, to 0.12‐0.13 at about 150 days of age, stayed more or less constant at 0.14‐0.16 until 270 days of age and increased with age after that, up to 0.25‐0.26. Maternal heritability estimates increased from birth (0.01) to a peak of 0.14 for data sets 1 and 0.07‐0.08 for data sets 2 at about 180‐210 days of age, before decreasing slowly to 0.07 and 0.05, respectively, at 300 days, and then rapidly diminished after 300 days of age. Permanent environmental effects were 1.5 to four times higher than genetic maternal effects and showed a similar trend.
Reorganization of Firms and Labor Market Inequality

This paper explores the implications of the ongoing reorganization of firms for inequality in the labour market. We show how recent technological advances in physical and human capital can lead to the breakdown of occupational barriers, creating demands for new combinations of skills, and thereby leading to new patterns of wage inequality. Specifically, our analysis indicates how the changes can segment the labour market into an expanding sector of restructured firms where wages are rising, a contracting sector of traditional firms where wages are relatively stagnant, and an expanding pool of the unemployed. The analysis helps explain various significant labour market phenomena, such as: the increased versatility of work; the widening dispersion of wages within occupational, educational, and job tenure groups in the United Kingdom and the United States, accompanied by a narrowing of the male-female wage differentials; the reorganization of firms from task-oriented departments to customer-oriented teams; and the breakdown of occupational barriers.
European indexed investments: how to identify the most efficient index

This article provides a guideline for the evaluation of index efficiency, with a focus on the euro area stock markets. Efficiency plays a key role in defining the level of risk-adjusted performance reached by an investment, and it becomes gradually more important as the share of indexed investments increases within the portfolio. The theoretical assumptions of the Modern Portfolio Theory (MPT) and of the Capital Asset Pricing Model (CAPM) provide the background for the statistical tests employed in the empirical analysis, carried out on the most important indices representative of the euro area stock markets. Indices have been selected according to quali-quantitative criteria, in order to include most of the construction techniques available on the market. The tests comprise robust techniques based upon simulation processes, such as the bootstrap, block-bootstrap and resampling. The results of the analysis show the relevant influence of equal weighting schemes upon the level of efficiency, an outcome that is apparently in contrast with the CAPM and, to a lesser extent, the MPT, but that can be justified both by statistical and behavioral models.
Spatial prediction filtering for increased penetration depth in synthetic aperture ultrasound

Synthetic aperture ultrasound is an imaging technique using channel data for every transmit and receive element combinations to achieve two-way focusing at all depths. One of its main drawbacks is reduced penetration depth because of lower reduced transmit power on each transmit event. To mitigate this problem, we employ a spatial prediction filtering technique called the frequency-space prediction filtering (FXPF) to enhance the signal-to-noise ratio (SNR) and thus, improve penetration depth in synthetic aperture ultrasound imaging. Our point target simulation and experimental phantom results show that FXPF is highly effective in enhancing the penetration depth and visibility of cyst targets, particularly for those at deep locations.
Antibacterial Susceptibility Pattern of Pathogenic Bacteria Isolates from Vegetable Salad Sold in Restaurants in Zaria, Nigeria

Microbiological analysis of 25 vegetable salad samples collected from five locations in Zaria, Nigeria was analysed using standard microbiological methods. Antibiotic susceptibility pattern of the isolates was determined using Kirby-Bauer CLSI modified disc agar diffusion technique (DAD). Antibacterial susceptibility of the isolates to aqueous and ethanol extracts of dry ginger; ethanol extract of fresh ginger (Zingiber officinale) was also investigated using agar diffusion and broth dilution methods. The bacterial load of the salad samples ranged between 6.0 x 10 4 to 2.0 x 10 6 cfu/ml. The pre- dominant bacteria isolated from the samples were Staphylococcus aureus, Salmonella spp, Escherichia coli and Pseudo- monas aeruginosa. All the bacteria isolates were found to be sensitive to Ofloxacin while Amoxycilin was found to be the least effective as all the bacteria isolates were resistant to it except a strain of Escherichia coli. Some of the strains of these isolates showed multiple antibiotic resistance to the antibiotics used. The aqueous and ethanol extracts of ginger showed moderate antibacterial activity against the isolates with diameter of zones of inhibition ranging from 13.0 to 28.5 mm. The Minimum Inhibitory Concentration (M.I.C.) and Minimum Bactericidal Concentration (M.B.C) values observed from the extracts against the organisms were moderately high. This study has shown that some vegetable salads are heavily con- taminated with potential pathogenic and antibiotic resistant bacteria species; ginger can be an alternative remedy to inhibit pathogenic bacteria isolates from vegetable salad.
Investigation of the efficacy of immunocastration aimed at the prevention of sex odour in boar meat

Disadvantage of meat known as boar taint is caused by steroids, androstenone being of particular importance, as well as indole and its derivatives, among which the best known is skatole. The common practice in Europe, in order to control these changes in meat, is castration without anesthesia. This intervention causes pain and stress to animals, thus undermining animal welfare. Many countries considering animal welfare try to find the alternative solutions in order to avoid castration. The alternative to surgical castration and possible solution to the problem of sex odour in the meat, as well as androstenone and skatole contents decrease in the boar's fat is immunological castration of boars (immunocastration). Average skatole content in fat tissue of boars was significantly higher (0.21±0.03 μg/g) compared to skatole content in fat tissue of the castrates, or immunocastrates (0.12±0.02 μg/g). In adipose tissue of the castrates and immunocastrates there was no significant difference in the average content of skatole. The content of androstenone in the adipose tissue of immunocastrates was below detection limits, and the average androstenone level in adipose tissue of boars was 0.66±0.13 μg/g. The obtained results show that immunocastration is justified in consideration of the meat quality and can completely replace castration in male animals, which is in compliance with the preservation of animal welfare in rearing fattening young boars.
Genetic Gain in Grain Yield Potential and Associated Agronomic Traits in Haricot Bean (Phaseolus vulgaris L.)

A yield potential experiment was conducted with 16 haricot bean varieties (10 released and 6 elite lines) developed by Ethiopian bean breeding program from 1972 to 1998 along with one local check (farmers’ variety). The objectives were to understand the genetic gain made in grain yield potential and to determine changes produced on agronomic traits associated with genetic yield potential improvement. The varieties were evaluated in RCB design at Awassa Agricultural Research Center experimental field to estimate the genetic gain in grain yield and the other fifteen agronomic traits. The analysis of variance revealed significant difference among varieties for all traits except the harvest index. The overall increase in grain yield over the local check, Red Wolayta, was estimated to be 1,604 kg/ha (82.4%). Based on the regression analysis, the estimated average annual rate of increase in grain yield potential was 69.45 kg/ha/year with an annual relative genetic change of 3.24%/year. Genotypic change was an important source of increased grain yield potential during the period studied. Absence of plateau indicated a possibility of further progress in grain yield using the same procedure, i.e. developing varieties from introduced germplasm. Correlation analysis indicated that grain yield was positively correlated with yield per plant, biomass yield, the number of seeds per plant, seed growth rate, grain yield per day and biomass production rate. The stepwise regression analysis showed that biomass yield was greatly contributed to the variation among the varieties in grain yield. Improvement for high grain yield was potential in haricot bean occurred over the past 26 years, in part, by grain yield improvement per se. However, the improvement was also associated with paralleled increase in biomass yield, the number of seeds per plant, seed growth rate, grain yield per day and biomass production rate.
Role of microhabitats in food webs of benthic communities in a mangrove forest

Mangrove benthic macro-invertebrate communities have access to various food sources. The food web in this system may not be based on homogenous mangrove detritus. In order to deter- mine the contributions of mangrove leaf litter and microalgae to the benthic macro-invertebrate com- munity, we analyzed carbon and nitrogen stable isotope ratios in primary producers (mangrove leaf litter, phytoplankton and microphytobenthos), particulate organic matter, sedimentary organic mat- ter and benthic macro-invertebrates from 3 microhabitats (tidal creeks, inside forests and forest gaps) in a mangrove forest in Trang province, Thailand. The stable isotope values of particulate and sedi- mentary organic matter did not differ greatly between microhabitats, and values were relatively sim- ilar to mangrove leaf litter. Invertebrates from tidal creeks and inside forests also showed δ 13 C values similar to mangrove leaf litter, whereas invertebrate tissues from forest gaps were close to micro- phytobenthos δ 13 C values. Most invertebrates showed an enriched δ 15 N value compared to the local particulate and sedimentary organic matter. These results indicate that invertebrates utilize different food sources in different microhabitats; they utilized mainly mangrove detritus in the tidal creeks and inside forests, but mainly microphytobenthos in the forest gaps. Moreover, the invertebrate biomass was highest in the forest gaps. This is important new information supporting the view that the man- grove food web is actually a diverse combination of webs based on a variety of resources, including homogenous mangrove detritus.
Stereotype Threat TASK PERFORMANCE SUBVERSION MAJOR FINDINGS ON STEREOTYPE THREAT IN ACADEMIC DOMAINS WAYS TEACHERS CAN STRUCTURE CLASSROOMS TO REDUCE STEREOTYPE THREAT

According to Steele and Aronson (1995), stereotype threat is defined as a “socially premised psychological threat that arises when one is in a situation or doing something for which a negative stereotype about one's group applies” (Steele, 1997, p. 614). Another description of stereotype threat suggests that individuals are at risk of confirming a negative stereotype about their group. Here, individuals who experience stereotype threat are 1) acknowledging that a negative stereotype exists (i.e., salient in a given context or is explicitly stated) about the capabilities of their social group (i.e., race/ethnicity, gender, age, socio-economic status) and 2) demonstrating apprehension about confirming the negative stereotype by engaging in particular activities.
Clock generation and distribution for the first IA-64 microprocessor

The clock design for the first implementation of the IA-64 microprocessor is presented. A clock distribution with an active distributed deskewing technique is used to achieve a low skew of 28 ps. This technique is capable of compensating skews caused by within-die process variations that are becoming a significant factor of the clock design. The global, regional and local clock distributions are described. A multilevel skew budget and local clock timing methodology are used to enable a high-performance design by providing support for intentional clock skew injection and time borrowing. By providing a test access port interface to the deskew architecture and the incorporation of the on-die-clock-shrink, this design is equipped with two very powerful post-silicon timing debug tools that are critical to high-performance microprocessor design and enabled quick time-to-market.
A World Wide Web for Robots •

H umans can use the Internet to share knowledge and to help each other accomplish complex tasks. Until now, robots have not taken advantage of this opportunity. Sharing knowledge between robots requires methods to effectively encode, exchange, and reuse data. In this article, we present the design and first implementation of a system for sharing knowledge between robots. In the manufacturing and logistics industries, robotic systems have brought significant sociological and economic benefits through improved human safety, increased equipment utilization, reduced maintenance costs, and increased production. In a world that is undergoing significant environmental and social change, there will be an increasing demand for these robots to leave the safety of their controlled environments and operate in the real world. Robots will be required to operate in homes and hospitals to service the health of a rapidly aging population, and they will be required to mine and farm in increasingly remote locations. In these environments, robots will need to reliably perform tasks beyond their explicitly preprogrammed behaviors and quickly adapt to the unstructured and variable nature of tasks. Although there has been much progress in task performance with well-defined sets of objects in structured environments, scaling current algorithms to real-world problems has proven difficult. Today's robots can only perform highly specialized tasks, and their operation is constrained to a narrow set of environments and objects. The majority of the world's 8 million service robots are toys or drive in preprogrammed patterns to clean floors or mow lawns, while most of the 1 million industrial robots repetitively perform preprogrammed behaviors to weld cars, spray paint parts, and pack cartons [1]. To date, the vast majority of academic and industrial efforts have tackled these challenges by focusing on increasing the performance and functionality of isolated robot systems. However, in a trend mirroring the developments of the personal computing (PC) industry [2], recent years have seen first successful examples of augmenting the computational power of individual robot systems with the shared memory of multiple robots. In an industrial context, Kiva Systems successfully uses systematic knowledge sharing among 1,000 individual robots to create a shared world model that allows autonomous navigation and rapid deployment in semistruc-tured environments with high reliability despite economic constraints [3], [4]. Other examples for shared world models include research on multiagent systems, such as RoboCup [5], where sharing sensor information has been shown to increase the success rate of tracking …
A hybrid islanding detection technique using average rate of voltage change and real power shift

The mainly used islanding detection techniques may be classified as active and passive techniques. Passive techniques don't perturb the system but they have larger non-detection zones, whereas active techniques have smaller non-detection zones but they perturb the system. In this paper, a new hybrid technique is proposed to solve this problem. An average rate of voltage change (passive technique) has been used to initiate a real power shift (active technique), which changes the real power of distributed generation (DG), when the passive technique cannot have a clear discrimination between islanding and other events in the system. Simulation results show that the proposed method is effective in detecting islanding of distribution systems with DGs.
On the Effectiveness of Inflation Targeting : Evidence from Semi / nonparametric Approach

This paper estimates the treatment effect of inflation targeting for 27 explicit inflation targeting countries. Our approach takes into account the problem of model misspecification and inconsistent estimation of parametric propensity scores by using a nonparametric series estimator proposed by Hirano, Imbens and Ridder (2003) and semiparametric single index method suggested by Klein and Spady (1993) and Song (2014). In addition, our paper also examines the impact of inflation targeting regime on a wider set of macroeconomic outcomes. Our findings suggest that results are sensitive to the choice of propensity score estimates based on different methods, and the semiparametric single-index model of propensity score provides the most economically meaningful results. Our findings illustrate that the inflation targeting framework significantly lowers inflation variability and improves fiscal discipline. We find that this monetary policy regime reduces the real exchange rate volatility in developing countries but increases it in developed economies.
Compressor surge control using a variable area throttle and fuzzy logic control

In this paper we present a new fuzzy control approach to compressor surge control. A variable area throttle is used in this strategy. The controller uses measurements of the mass flow rate and the change of mass flow rate to determine the control action. By using the change of mass flow rate, the controller does not need to know where the operating point is. One advantage of the proposed controller is that it does not need a mathematical model of the controlled compressor and it works on any centrifugal compressors. The fuzzy rules are transferable and only the scaling factor and the throttle capacity need to be changed when the controller is applied to another compressor of the same type. Simulation results show that the proposed controller gives good performance in various situations.
