Desempenho, características de carcaça e qualidade da carne de bovinos superprecoces das raças Canchim, Nelore e seus mestiços

Eighty six young bulls were used, divided into four genetic groups: Nellore (n=20), Canchim (n=17), ½ Canchim ×Nellore (NC) (n=25) and ¾ Canchim ×Nellore (TQ) (n=24). The animals were weighed every 28 days to evaluate the average daily gain (kg/day), dry matter intake (kg/day) and feed conversion. When the animals reached slaughter weight (450 kg) and fat thickness greater than 4 mm, were slaughtered to evaluate the rib eye area (cm2), subcutaneous fat thickness (mm), marbling, shear force, ether extract (%) and total cooking losses. The Nellore group fitted correctly into the proposed system, showing similar performance when compared to the CN group (1.18 and 1.29 kg/day for Nellore and CN, respectively) and feed conversion (6.90 and 7.04 for Nellore and CN, respectively). The dry matter intake (kg/day) differed among all groups (11.82, 9.39, 8.90 and 8.31 for Canchim, TQ, CN and Nellore, respectively). The carcass weight (kg) was higher in the Canchim group (291.14) than the other groups (250.74, 246.64 and 244.18 for TQ, CN and Nellore respectively). Although the carcass dressing percentage of the Nellore group (58.75%) was the highest, this group had the lowest yield of commercial cuts in the hindquarter especially for the sirloin (10.22, 11.55, 11.64 and 11.18% for Nellore, Canchim, TQ and CN, respectively). The shear force values indicated that the slaughter of young animals can assure tender beef regardless of the genetic group.
Impact of Governance Facets and Indian Companies Performance: An Empirical Study

The question of corporate governance in India has come mainly in the wake of economic liberalization, deregulation of industry and business as also the demand for a new corporate ethos and stricter compliance with the legislation. The new economic policies adopted by the Government of India since 1991 has necessitated the demand for introduction and implementation of a proper corporate governance policy in management of companies not only in the interests of their stakeholders but also for the overall development of the country. The study of corporate governance has important public policy implications relating to the role of government and the markets in disciplining management. Corporate Governance is considered to have significant implications for the growth prospects of an economy. Good Corporate Governance practices are regarded as important in reducing risk for investors, attracting investment capital and improving the performance of the firms. However, the way in which corporate governance is organized differs between countries, depending on their economic, political and social contexts. With a view to add to the existing stock of knowledge in this discipline of finance, the current research work makes an attempt to examine the impact of a package of governance mechanisms on both market and accounting measures of performance by confining itself to a cross- section of companies within a single jurisdiction of India. Given the importance of the research problem to the field of corporate finance and for resolving the inconsistent research findings in the prior literature, the relation between governance and performance of firms have been looked into. For carrying out the above objectives, the corporate governance information relating to Board of directors, ownership structure, Audit committee, Remuneration committee and grievance committee and their financial statements are collected through secondary source. Different performance measures spread across three categories: operating performance, market value added and shareholder payout are used in the study. Operating performance would be measured through return on equity, profit margin and sales growth. To represent the market value added, the study used P/B ratio that are collected from the website of Bombay Stock exchange. P/B is in fact the single MVA measure considered by economics, finance and law researchers. Further the performance measures like EBITDA margin, ROE, Sales growth are collected from the PROWESS (CMIE) data base. The study made an attempt to focus on five years data from 2006-2010 but due to non-availability of data of 5 years for all the companies finally the study could include only 163 companies from the BSE 200 list. The purpose of this research paper was to examine the relationship between corporate governance practices and firm performance in India. A correlation matrix has been presented to describe the linear relationship between five governance facets and six performance variables.
Marketing Portfolio Choices by Independent Peach Growers: An Application of the Polychotomous Selection Model

In selecting a marketing channel for fresh peach sales, Georgia commercial peach growers choose the channel after accounting for buyers' preferences for quality attributes. Using the polychotomous selection model and survey data we identified external and internal quality attributes as essential factors influencing the choice of a marketing channel and the share of the crop marketed. Other factors influencing the choice and the volume sold through each marketing channel included orchard characteristics and the variety-determined fruit maturity.
Bounded chosen ciphertext secure cryptosystems based on computaional Diffie-Hellman and hashed Diffie-Hellman assumptions

We propose two constructions of chosen-ciphertext secure cryptosystems against adversaries with a bounded number of decrytion queries based on the ElGamal encryption scheme [15]. We rely our work on weak computational assumptions, and the ciphertext overhead of the resulting schemes will be only one group element which is considered optimal since it is the same as the original ElGamal. Disadvantages to known schemes are that the upper bound of the number of decryption queries has to be known before set-up phase.
Reconstructing Political Order Among the Somalis: The Historical Record in the South and Centre

The reconstruction of a larger polity in a violence‐torn society such as Somalia requires negotiation of a new social contract between the superordinate body and the local units of governance that have provided citizens some degree of order throughout the conflict. In this article we show that the very different trajectories for state‐building in the north and south of the country result in good part from different attention to this generalisation. The founding leaders in Somaliland and Puntland consulted extensively with the assemblies of elders and were able to create civilian constitutional orders. Military leaders in the south and central regions did not incorporate their elders into their political systems, even though they controlled similar amounts of territory to their counterparts in the north. Ultimately various Islamic movements did build on community‐level governance and used it to successfully challenge the old ‘warlords’ but most of those allied with the Transitional Federal Government remain weak at the community base.
Forecasting monthly groundwater level fluctuations in coastal aquifers using hybrid Wavelet packet–Support vector regression

Abstract This research demonstrates the state-of-the-art capability of Wavelet packet analysis in improving the forecasting efficiency of Support vector regression (SVR) through the development of a novel hybrid Wavelet packet–Support vector regression (WP–SVR) model for forecasting monthly groundwater level fluctuations observed in three shallow unconfined coastal aquifers. The Sequential Minimal Optimization Algorithm-based SVR model is also employed for comparative study with WP–SVR model. The input variables used for modeling were monthly time series of total rainfall, average temperature, mean tide level, and past groundwater level observations recorded during the period 1996–2006 at three observation wells located near Mangalore, India. The Radial Basis function is employed as a kernel function during SVR modeling. Model parameters are calibrated using the first seven years of data, and the remaining three years data are used for model validation using various input combinations. The performance of both the SVR and WP–SVR models is assessed using different statistical indices. From the comparative result analysis of the developed models, it can be seen that WP–SVR model outperforms the classic SVR model in predicting groundwater levels at all the three well locations (e.g. NRMSE(WP–SVR) = 7.14, NRMSE(SVR) = 12.27; NSE(WP–SVR) = 0.91, NSE(SVR) = 0.8 during the test phase with respect to well location at Surathkal). Therefore, using the WP–SVR model is highly acceptable for modeling and forecasting of groundwater level fluctuations.
THE EFFECT OF WEDM CUTTING PARAMETER ON INCONEL 718 SUBSURFACE MICROHARDNESS

This paper reports on the effect of wire electrical discharge machine (WEDM) cutting parameter on the subsurface hardness of Inconel 718. The response surface methodology (RSM) using Box-Behnken design was used to conduct the experiment and analyze the relationship between control variables and responses. A total of 8 runs was carried out during the experiment. The Historical Data of Response Surface Methodology (RSM) was used as a tool of design of experiment (DOE). The selected WEDM parameters were Voltage (40-42V), feed rate (6-8V) and current (0.5-1.5 mm/min). The subsurface hardness was measured at the distance of 50 μm, 100 μm, 300 μm, 500 μm beneath the cutting surface. Observation of the results shows that the subsurface hardness is higher at the distance of 50μm than 500 um. The hardness was gradually decreased toward bulk hardness of HV0.1 270. Analysis of variance (ANOVA) was used to identify the significant effect of the factors on the response. Based on the analysis, feed rate and current were found to be the most significant factors in hardness change. Mathematical models were developed for hardness prediction with an average error of 2.7%. The minimum hardness change of HV0.1 30 was obtained by the combination of feed rate = 1.29 mm/min, servo voltage = 40.33 V, current = 7.94 A.
Neural mass model parameter identification for MEG/EEG

Electroencephalography (EEG) and magnetoencephalography (MEG) have excellent time resolution. However, the poor spatial resolution and small number of sensors do not permit to reconstruct a general spatial activation pattern. Moreover, the low signal to noise ratio (SNR) makes accurate reconstruction of a time course also challenging. We therefore propose to use constrained reconstruction, modeling the relevant part of the brain using a neural mass model: There is a small number of zones that are considered as entities, neurons within a zone are assumed to be activated simultaneously. The location and spatial extend of the zones as well as the interzonal connection pattern can be determined from functional MRI (fMRI), diffusion tensor MRI (DTMRI), and other anatomical and brain mapping observation techniques. The observation model is linear, its deterministic part is known from EEG/MEG forward modeling, the statistics of the stochastic part can be estimated. The dynamics of the neural model is described by a moderate number of parameters that can be estimated from the recorded EEG/MEG data. We explicitly model the long-distance communication delays. Our parameters have physiological meaning and their plausible range is known. Since the problem is highly nonlinear, a quasi-Newton optimization method with random sampling and automatic success evaluation is used. The actual connection topology can be identified from several possibilities. The method was tested on synthetic data as well as on true MEG somatosensory-evoked field (SEF) data.
A CORRECTION FACTOR FOR PRESSURE DISTRIBUTION ANALYSIS OF AN AEROFOIL IN A SUBSONIC FLOW

@This study investigates the solution for a given pressure (i.e. velocity) distribution of subsonic flow around an a erofoil section using an analytical method. The results show that the analyt ical method is not precise on the leading edge, when it is used to solve the mean camber line of updated profile RAE (Royal Aircraft Establishment). Therefore , a correction parameter with changeable values ranging between 0.32 and 0.42 was created, and it gives appropriate results. —‚U½a@
Dwyer–Kan homotopy theory for cyclic operads

Abstract We introduce a general definition for coloured cyclic operads over a symmetric monoidal ground category, which has several appealing features. The forgetful functor from coloured cyclic operads to coloured operads has both adjoints, each of which is relatively simple. Explicit formulae for these adjoints allow us to lift the Cisinski–Moerdijk model structure on the category of coloured operads enriched in simplicial sets to the category of coloured cyclic operads enriched in simplicial sets.

Discrete-Time Indefinite Stochastic Linear Quadratic Optimal Control with Second Moment Constraints

This paper studies the discrete-time stochastic linear quadratic (LQ) problem with a second moment constraint on the terminal state, where the weighting matrices in the cost functional are allowed to be indefinite. By means of the matrix Lagrange theorem, a new class of generalized difference Riccati equations (GDREs) is introduced. It is shown that the well-posedness, and the attainability of the LQ problem and the solvability of the GDREs are equivalent to each other.
The use of contingent valuation in assessing marine and coastal ecosystems’ water quality: A review

Marine and coastal ecosystems are of high importance owing to the mankind dependence on the goods and services provided. As water quality is one perspective of healthy marine and coastal ecosystems, the aim of this study is to review as more as possible surveys conducted worldwide and in Greece. Due to the lack of an official market to valuate non-marketed goods and services, contingent valuation is applied intensively in order to provide the policy makers and the society generally with the specific values derived by a developed hypothetical market. In addition, this study reviews the crucial but debatable notion of value, the theoretical framework in accordance with the existing statistical models to estimate the welfare measures and the numerous disadvantages that have to be taken into account in order to implement a reliable contingent valuation survey.
Role of Nutraceuticals in Modulation of Gut-Brain Axis in Elderly Persons

A rather new and somewhat unusual concept connects brain functions to gut microbiota. It is called “gut-brain axis” (or “microbiota-gut-brain axis”) and states that probiotics consumption and a healthy gut microbiota positively influence brain functions related to behavior and cognition. Synergistic with a low chronic grade peripheral inflamma tion, this faulty barrier exposes the aged brain to negative extra-cerebral signals. Given the quasi-constant failure of pharmacological treatments in neurodegenerative diseases, increased interest is directed toward allopathic medicine, including dietary supplements. Interplay between gut microbiota and central nervous system by immune, neural and metabolic pathways is being explored as a possible modulator of cognitive impairment and behavior disorders. In elderly persons, this axis has been reported to be altered, contributing to systemic inflammation and was also indicated as a possible marker for early frailty in younger population. Currently, there are several clinical trials addressing the relationship between gut microbiota and central nervous system psychiatric disorders and at least one directly investigating whether there is a correlation between composition of gut microbiome, permeability of intestinal barrier and systemic inflammation in patients with dementia. This chapter discusses evidence-based data on positive modulation of gut-brain axis to alleviate behavior and cognition alterations in the elderly. inputs. A third player with a determinant role in the health of both systems is the gut microbiota. Aging affects all players of the microbiota-gut-brain axis, leading to modified com position of bacterial taxa, chronic low-grade inflammation, modified intestinal metabolism, resulting in diminished availability of neurotransmitters or neurotransmitter precursors and short-chain fatty acids. Along with synaptic impairment, oxidative stress and neuroinflam mation, aging leads to behavior alterations, anxiety and cognitive impairment. Interventions on gut-brain axis with nutraceuticals (food or food-derived products that have putative beneficial effects) alleviate some age-associated behavioral and cognitive alterations, as repeatedly demonstrated in animal models. Recently, clinical trials have begun to explore the beneficial effect of gut-brain axis modulation, in mood or cognition-associated disorders. Upon reports of positive results, gut-brain axis emerges as an important, easy to access target for promoting a healthy brain aging. Intestines.
How High Involvement Work Systems Influence R&D Professional's Innovative Performance: An Analysis of the Mediated Moderation Effect

In this study, a mediated moderation model has been constructed based on 356 RD (2) consciousness moderates the effect of high involvement work systems on professional's innovative performance; (3) supervisor trust mediates the moderating effect of consciousness between high involvement work systems and professional's innovative performance. Introduction HIWSs refer to a group of human resource (HR) practices, and have received significant attention among scholars. The relationship between HIWSs and employee's attitudes and behaviors has been proved by an amount of empirical research [1]. However, most of the researches of HIWSs are aimed at manufacturing industry, and there have been few studies to select high tech industry's employees as subjects investigated. R&D professional's innovation is crucial to high tech enterprise's survival and development. So how to improve professional's innovative performance has become the urgent question to be solved. In past research, human resource management has been highlighted as one of the most influential factors in a firm’s innovative behaviors [2]. Therefore, in this study, we try to test whether HIWSs affect R&D professional's innovative performance. In the Big Five personality model, consciousness has been considered to have significant impact on employee's job performance [3]. That is to say, in the same work environment, individuals with different levels of consciousness may show different job performance. In addition, the effects of trust in supervisor on employee's attitudes and behaviors have attracted the attention of some scholars [4]. Therefore, we introduced consciousness and trust in supervisor, trying to explore their effects on the relationship between HIWSs and R&D professional's innovative performance.
Parametrical study of the transition scenario in the wake of oblate spheroids

An exhaustive parametric study of the transition scenario in the wake of oblate spheroids placed with their rotation axis parallel to the flow is presented. The flatness of the investigated objects is classified by the aspect ratio χ defined as χ = d/a (with d the diameter and a the length of the polar axis). At large aspect ratios (χ > 2.3), the secondary bifurcation giving rise to a periodic state without planar symmetry is subcritical with a hysteresis interval of about two Reynolds number units. For small aspect ratios (χ ≥ 1 are considered), the sphere-like scenario is recovered only at aspect ratios very close to one. For intermediate aspect ratios, a domain of states with non zero net helicity separates states typical for the sphere wake from those of an infinitely flat disk.

The Association between Physical Fitness, Body Composition and Bone Mineral Density among Female Athletes

Background: Research have suggested that endurance female athletes tend to have lower bone mineral density (BMD) than power and strength athletes, as a result of maintaining low body weight in addition to perform. This study intends to investigate the association between physical fitness by power and endurance measurements, body composition and BMD. In addition, it will address the differences in BMD measured in female football players, handball players and cross-country skiers.Methods: A cross-sectional study of 57 Norwegian female athletes aged between 18 and 36 years (mean age 22.6 years) was conducted. The sample consisted of 24 football players, 17 handball players and 16 cross-country skiers. For physical fitness examinations, a graded VO₂max (ml/kg/min) test on treadmill, squat jump on a power plate and bench press with free weights were conducted. Body weight and height was measured and BMI calculated from the aforementioned variables. Lean body mass, body fat percentage and BMD (g/cm²) was measured using Dual- Energy X-ray Absorptiometry. BMD was obtained from four different regions, in addition to total body BMD: Ward’s triangle, Trochanter, femoral neck and lumbar region (L1-L4). Results: Significant association between body composition and BMD was observed for all subjects combined. Also, significant associations between the physical fitness tests and BMD were obtained. Differences in body composition and physical fitness level among the athletes indicated that the cross-country skiers had lower body weight, BMI, lean body mass and body fat percentage. Cross-country skiers also had the highest mean oxygen consumption among the female athletes and also the lowest BMD in all regions. Handball players had higher mean body weight, BMI, lean body mass and fat percentage. Handball players also had the higher mean BMD values for all regions measured.Conclusion: Body composition was strongly associated with BMD in all regions measured. Subjects with high oxygen had lower BMD measurements in all regions while subjects with high muscular power in lower body had the highest BMD measurements in all regions. Also, differences in BMD between the three sports suggested that cross-country skiers have lower BMD values than both football players and handball players, in all regions measured.Keywords: Female athletes, physical fitness, body composition, bone mineral density (BMD).
The Effect of Performance-Pay in Little Rock, Arkansas on Student Achievement. Working Paper 2008-02.

is paper examines evidence from a performance-pay program implemented in five Little Rock, Arkansas elementary schools between 2004 and 2007. Using a differences-in-differences approach, the evidence shows that students whose teachers were eligible for performance pay made substantially larger test score gains in math, reading, and language than students taught by untreated teachers. Further, there is a negative relationship between the average performance of a teacher’s students the year before treatment began and the additional gains made aer treatment. at is, performance-pay in Little Rock appears to have improved student achievement and to have done so more for students of teachers who were previously less effective at producing learning gains.
