A Survey of Management Practices That Influence Performance and Welfare of Dairy Calves Reared in Southern Brazil

Here we report dairy calf management practices used by 242 smallholder family farmers in the South of Brazil. Data were collected via a semi-structured questionnaire with farmers, inspection of the production environment and an in-depth interview with a sample of 26 farmers. Herds had an average of 22.3 lactating cows and an average milk production of 12.7 L/cow/day. Calves were dehorned in 98% of the farms, with a hot iron in 95%. Male calves were castrated in 71% of the farms; methods were surgery (68%), emasculator (29%), or rubber rings (3%). No pain control was used for these interventions. In 51% of the farms all newborn male calves were reared, sold or donated to others; in 35% all newborn males were killed on the farm. Calves were separated from the dam up to 12 h after birth in 78% of the farms, and left to nurse colostrum from the dam without intervention in 55% of the farms. The typical amount of milk fed to calves was 4 L/day until a median age of 75 days. In 40% of the farms milk was provided in a bucket, in 49% with bottles, and in 11% calves suckled from a cow. Solid feeding in the milk-feeding period started at a median age of 10 days. Calves were housed individually in 70% of the farms; in 81% of the farms calves were housed in indoor pens, in 6% in outdoor hutches and in 13% they were kept on pasture. Diarrhoea was reported as the main cause of calf mortality in 71% of the farms. Farmers kept no records of calf disease, mortality, or use of medicines. Changing the scenario identified in this survey is essential to support the sustainable development of dairy production, an activity of great economic and social relevance for the region.
Cancer incidence in the agricultural health study.

OBJECTIVES This large, prospective cohort study of private applicators, commercial applicators, and spouses of farmer applicators was undertaken to ascertain the etiology of cancers elevated in agriculture. METHODS The participants were matched to cancer registry files in Iowa and North Carolina. Incident cases were identified from enrollment through 31 December 2002. Standardized incidence ratios (SIR) were used to compare the cancer incidence of the participants with that of the total population in the two states. RESULTS The overall cancer incidence among farmers [SIR 0.88, 95% confidence interval (95% CI) 0.84-0.91] and their spouses (SIR 0.84, 95% CI 0.80-0.90) were significantly lower than expected, particularly for respiratory and urinary cancers. Commercial pesticide applicators had an overall cancer incidence comparable with the expected (SIR 1.01, 95% CI 0.84-1.20). Smoking prevalence was significantly lower than the national average. Prostate cancer was elevated among private applicators (SIR 1.24, 95% CI 1.18-1.33) and commercial applicators (SIR 1.37, 0.98-1.86). Excess ovarian cancer was observed for female applicators (SIR 2.97, 95% CI 1.28-5.85), but not for female spouses (SIR 0.55, 95% CI 0.38-0.78). Female spouses had a significant excess of melanoma (SIR 1.64, 95% CI 1.24-2.09), which was not observed among pesticide applicators. CONCLUSIONS Low overall cancer incidence rates seem to be a result of low overall smoking prevalence and other lifestyle factors, while excess cancer of the prostate and ovaries among applicators may be occupationally related. The excess risk of melanoma observed among spouses was unexpected.
New Media and Political Efficacy

Building upon findings from a series of nine nationally-representative panel surveys, focus groups were conducted within the Leeds area in order to explore ways in which a broad range of participants interact with and reflect upon structures of political power, both within their local communities and beyond. The paper considers four themes discussed by focus group participants: Firstly, the ways in which people establish confidence in their local environment and how these relate to a growing estrangement between local and political worlds; secondly, the perceived potential of the Internet for acquiring useful information and linking with like-minded others; thirdly, the disconnection between participants’ sense of local belonging and their capacity to influence the affairs of their locality through electing accountable political representatives; and fourthly, the value of the Internet as a space for symbolic display: a means of asserting solidarity in the absence of physical association. The paper concludes by discussing the theoretical implications of this research and considering the role of the media in creating ‘confidence-building devices’ that might enhance political efficacy.
Direct Numerical Simulation of Differential Scalar Diffusion in Three-Dimensional Stratified Turbulence

Abstract The potential for differential turbulent transport of oceanic temperature (T) and salinity (S) is explored using three-dimensional direct numerical simulations of decaying stratified turbulence. The simulations employ a realistic molecular diffusion coefficient for T, and one for a “salt” scalar S that is 10 times smaller. Initially, a uniformly stratified medium is disturbed by a turbulent burst whose initial energy is assigned a range of values. In each instance, transports of T integrated over the subsequent decay of the burst exceed those of S. The more energetic cases occupy parameter ranges similar to, and exhibit spectral characteristics that are essentially indistinguishable from, those of direct observations of turbulence in the stratified ocean interior. In these cases, the turbulent diffusivity of T exceeds that of S by 6%–22%. These simulations underestimate the degree of differential diffusion between T and salinity S (which has a molecular diffusivity 100 times less than T); thus at.
CD4+CD25+ regulatory T cells control CD8+ T-cell effector differentiation by modulating IL-2 homeostasis

CD4+CD25+ regulatory T cells (Treg) play a crucial role in the regulation of immune responses. Although many mechanisms of Treg suppression in vitro have been described, the mechanisms by which Treg modulate CD8+ T cell differentiation and effector function in vivo are more poorly defined. It has been proposed, in many instances, that modulation of cytokine homeostasis could be an important mechanism by which Treg regulate adaptive immunity; however, direct experimental evidence is sparse. Here we demonstrate that CD4+CD25+ Treg, by critically regulating IL-2 homeostasis, modulate CD8+ T-cell effector differentiation. Expansion and effector differentiation of CD8+ T cells is promoted by autocrine IL-2 but, by competing for IL-2, Treg limit CD8+ effector differentiation. Furthermore, a regulatory loop exists between Treg and CD8+ effector T cells, where IL-2 produced during CD8+ T-cell effector differentiation promotes Treg expansion.
Src‐Tyrosine kinases are major agents in mitochondrial tyrosine phosphorylation

Mitochondrial tyrosine phosphorylation is emerging as an important mechanism in regulating mitochondrial function. This article, aimed at identifying which kinases are the major agents in mitochondrial tyrosine phosphorylation, shows that this role should be attributed to Src family members. Indeed, various members of this family, for example, Fgr, Fyn, Lyn, c‐Src, are constitutively present in the internal structure of mitochondria as well as Csk, a key enzyme in the regulation of the activity of this family. By means of different approaches, biochemical fractioning, Western blotting and immunogold analysis “in situ” of phosphotyrosine signaling, evidence is reported on the existence of a signal transduction pathway from plasma membrane to mitochondria, resulting in increasing Src‐dependent mitochondrial tyrosine phosphorylation. The activation of Src kinases at mitochondrial level is associated with the proliferative status where several mitochondrial proteins are specifically tyrosine‐phosphorylated. J. Cell.

Assesment of social support dimensions in patients with eating disorders.

UNLABELLED The aim of this study is to assess social support dimensions (providers, satisfaction and different support actions) in patients with eating disorders (ED), looking at diagnosis, socio-demographic and clinical characteristics, and self-concept. METHOD A total of 98 female ED patients were recruited. The ages of participants ranged from 12 to 34 (Mean = 20.8-years-old, SD=5.61). Patients have a primary DSM-IV-R diagnosis of anorexia nervosa (61.2%), bulimia nervosa (27.6%) or an unspecified eating disorder (11.2%). Social support was assessed using the Escala de Apoyo Social Percibido (EASP). This scale measures social support providers, satisfaction and specific social support actions, which can be grouped into informational, emotional and practical support. Self-concept was assessed using the Cuestionario de Autoconcepto (AF-5). RESULTS The two most frequent providers for these patients were mothers (86.7%) and partners (73.1%). Patients' satisfaction with social support was high and they reported that they received informational support more frequently than emotional and practical support. Family self-concept showed positive relationships with social support dimensions. CONCLUSION These results show the importance of the family network in connection with these disorders and its relation to self-concept.
What Matters More—Breaking Tradition or Stereotype Content? Envious and Paternalistic Gender Stereotypes and Advertising Effectiveness

The outcomes of 2 experiments investigating the effectiveness of advertisements that use (non)traditional stereotypes of women (Experiment 1) or men (Experiment 2) are reported. Effectiveness of the ads was tested in relation to perceivers' attitudes toward female or male gender roles, respectively. The main finding was that for both male and female versions of the advertisements, the paternalistic ad strategies were more effective than were the envious ones, supporting the predictions of the stereotype content model over the classic prediction of negative effects of nontraditional gender portrayals for advertising effectiveness. Moreover, attitudes toward gender roles played only a limited role in determining ad effectiveness. Theoretical and practical implications are discussed.
Leisure Attitude, Leisure Satisfaction, and Perceived Freedom in Leisure within Family Dyads

Interdependence theory suggests that individual attitudes, beliefs, and dispositions are influenced through long-term relationships. This study explored the role of interdependence in dyadic, or two-person, relationships within families (spouses, adult child and parent, and siblings) in shaping beliefs about, and perceptions of, leisure. The sample consisted of 272 predominantly Anglo college students and their family members, aged 17? 84. Participants completed the Leisure Attitude (LAS), Leisure Satisfaction (LSS), and Perceived Freedom in Leisure (PFL) Scales. Interdependence theory is partially supported as LAS scores were correlated for three family dyads, LSS scores were correlated for three family dyads, and PFL scores were correlated for four family dyads. It appears that family members experience a similar degree of enjoyment and sense of control in leisure even though interests and knowledge may vary.
Long‐term volumetric eruption rates and magma budgets

A global compilation of 170 time‐averaged volumetric volcanic output rates (Qe) is evaluated in terms of composition and petrotectonic setting to advance the understanding of long‐term rates of magma generation and eruption on Earth. Repose periods between successive eruptions at a given site and intrusive:extrusive ratios were compiled for selected volcanic centers where long‐term (>104 years) data were available. More silicic compositions, rhyolites and andesites, have a more limited range of eruption rates than basalts. Even when high Qe values contributed by flood basalts (9 ± 2 × 10−1 km3/yr) are removed, there is a trend in decreasing average Qe with lava composition from basaltic eruptions (2.6 ± 1.0 × 10−2 km3/yr) to andesites (2.3 ± 0.8 × 10−3 km3/yr) and rhyolites (4.0 ± 1.4 × 10−3 km3/yr). This trend is also seen in the difference between oceanic and continental settings, as eruptions on oceanic crust tend to be predominately basaltic. All of the volcanoes occurring in oceanic settings fail to have statistically different mean Qe and have an overall average of 2.8 ± 0.4 × 10−2 km3/yr, excluding flood basalts. Likewise, all of the volcanoes on continental crust also fail to have statistically different mean Qe and have an overall average of 4.4 ± 0.8 × 10−3 km3/yr. Flood basalts also form a distinctive class with an average Qe nearly two orders of magnitude higher than any other class. However, we have found no systematic evidence linking increased intrusive:extrusive ratios with lower volcanic rates. A simple heat balance analysis suggests that the preponderance of volcanic systems must be open magmatic systems with respect to heat and matter transport in order to maintain eruptible magma at shallow depth throughout the observed lifetime of the volcano. The empirical upper limit of ∼10−2 km3/yr for magma eruption rate in systems with relatively high intrusive:extrusive ratios may be a consequence of the fundamental parameters governing rates of melt generation (e.g., subsolidus isentropic decompression, hydration due to slab dehydration and heat transfer between underplated magma and the overlying crust) in the Earth.
Perceived organizational support and organizational trust in primary schools

The purpose of the present study is to determine the relationship between organizational support and organizational trust of teachers. Organizational support is recognizing the contribution of employees, appreciating and paying attention to them in the organizations. Organizational trust refers to an organizational climate that the employees behave each other in an honest, realistic, helpful and coherent way. The study sample involves 470 primary school teachers working in Tuzla during 2013-2014 educational year. In the present study, the data was collected through the perceived organizational support scale and trust scale. SPSS 21.00 programs were used in analysis of the data. The relationships was tested by Pearson Moments Product Correlation Coefficient. Regression Analysis was used for testing predictive power. Positive, low-level and significant correlations were found towards perceived organizational support and sub-dimensions with organizational trust. Regression analyzes revealed that organizational trust was positively predicted from educational support, administrative support and justice variables. Educational support predicts a high part of the variance. These three variables explain the 10 % of the organizational trust.
Evaluating a development centre

Aims to explore factors which are thought to relate to the effectiveness of development centre processes. Studies a variety of attitudinal and motivational aspects concerned with attendance at, and benefit from, a development centre. The research was carried out using an instrument which was completed by 60 managers who had attended a development centre organized by a major British company. Hypothesizes a model which links development centre benefits to process validity, pre‐centre factors, and biographical factors. Results show partial support for the model, confirming the strong link between benefits and process validity, but fail to demonstrate the importance of support from a participant’s manager. Factor analysis demonstrates three distinct sets of benefits which have been labelled: personal development; career development; and organizational commitment.
Number of active joints, not diagnosis, is the primary determinant of function and performance in early synovitis.

OBJECTIVE A substudy within a larger study of patients with inflammatory arthritis of less than one year, to analyze baseline measures or joint counts, laboratory values, patient questionnaires and ARA diagnostic criteria for rheumatoid arthritis, as predictors of one year performance and functional status. METHODS 229 patients with synovitis of less than one year were enrolled and evaluated at baseline and one year. Measures included the number of swollen or tender joints [active joint counts]; biological indices of inflammation [erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)]; and patient questionnaire measures of pain [Wisconsin Brief Pain Inventory], fatigue [multi-dimensional assessment of fatigue], depression [Center for Epidemiologic Studies--Depression Scale], sleep [Sleep Quality Index], performance [Human Activity Profile], and function [Sickness Impact Profile ambulation subscale and Health Assessment Questionnaire]. Correlations between these measures were evaluated using the Spearman rank order correlation. Patients were classified according to whether they met ARA criteria for RA, had high (> 7) or low (< or = 7) numbers of affected joints; and high, intermediate, or low levels of performance; and were compared using the Kruskal-Wallis test. RESULTS At baseline, an active joint count of > 7 versus < or = 7 was associated significantly with higher age, rheumatoid factor positivity, a diagnosis of rheumatoid arthritis versus spondyloarthropathy or undifferentiated arthritis, and receiving a disease modifying antirheumatic drug (DMARD), but not with sex, race, erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP), or receiving prednisone. Furthermore, high baseline active joint counts were associated significantly with patient questionnaire scores for maximum activity, fatigue and depression, but differences were not significant for sleep, ambulation and pain scores. A comparison of patients who met or did not meet criteria for RA indicated significant differences only according to the fatigue scores, but none of the other questionnaire measures. Correlations of baseline measures with one-year performance were highest for the baseline active joint count compared to laboratory and questionnaire variables. The maximum activity score at one year was predicted significantly by the baseline maximum activity score, active joint count, and age, but not by laboratory tests or whether the patient met criteria for RA. CONCLUSION The active joint count predicts subsequent performance and function for patients with recent onset, inflammatory synovitis more effectively than whether patients met ARA criteria for RA.
Genotypic Variation under Fe Deficiency Results in Rapid Changes in Protein Expressions and Genes Involved in Fe Metabolism and Antioxidant Mechanisms in Tomato Seedlings (Solanum lycopersicum L.)

To investigate Fe deficiency tolerance in tomato cultivars, quantification of proteins and genes involved in Fe metabolism and antioxidant mechanisms were performed in “Roggusanmaru” and “Super Doterang”. Fe deficiency (Moderate, low and –Fe) significantly decreased the biomass, total, and apoplastic Fe concentration of “Roggusanmaru”, while a slight variation was observed in “Super Doterang” cultivar. The quantity of important photosynthetic pigments such as total chlorophyll and carotenoid contents significantly decreased in “Roggusanmaru” than “Super Doterang” cultivar. The total protein profile in leaves and roots determines that “Super Doterang” exhibited an optimal tolerance to Fe deficiency compared to “Roggusanmaru” cultivar. A reduction in expression of PSI (photosystem I), PSII (photosystem II) super-complexes and related thylakoid protein contents were detected in “Roggusanmaru” than “Super Doterang” cultivar. Moreover, the relative gene expression of SlPSI and SlPSII were well maintained in “Super Doterang” than “Roggusanmaru” cultivar. The relative expression of genes involved in Fe-transport (SlIRT1 and SlIRT2) and Fe(III) chelates reductase oxidase (SlFRO1) were relatively reduced in “Roggusanmaru”, while increased in “Super Doterang” cultivar under Fe deficient conditions. The H+-ATPase relative gene expression (SlAHA1) in roots were maintained in “Super Doterang” compared to “Roggusanmaru”. Furthermore, the gene expressions involved in antioxidant defense mechanisms (SlSOD, SlAPX and SlCAT) in leaves and roots showed that these genes were highly increased in “Super Doterang”, whereas decreased in “Roggusanmaru” cultivar under Fe deficiency. The present study suggested that “Super Doterang” is better tomato cultivar than “Roggusanmaru” for calcareous soils.
Smart city for VANETs using warning messages, traffic statistics and intelligent traffic lights

Road safety has become a main issue for governments and car manufacturers in the last twenty years. The development of new vehicular technologies has favoured companies, researchers and institutions to focus their efforts on improving road safety. During the last decades, the evolution of wireless technologies has allowed researchers to design communication systems where vehicles participate in the communication networks. Thus, new types of networks, such as Vehicular Ad Hoc Networks (VANETs), have been created to facilitate communication between vehicles themselves and between vehicles and infrastructure. New concepts where vehicular networks play an important role have appeared the last years, such as smart cities and living labs [1]. Smart cities include intelligent traffic management in which data from the TIC (Traffic Information Centre) infrastructures could be reachable at any point. To test the possibilities of these future cities, living labs (cities in which new designed systems can be tested in real conditions) have been created all over Europe. The goal of our framework is to transmit information about the traffic conditions to help the driver (or the vehicle itself) take adequate decisions. In this work, the development of a warning system composed of Intelligent Traffic Lights (ITLs) that provides information to drivers about traffic density and weather conditions in the streets of a city is proposed and evaluated through simulations.
Quantifying the Performance of Workflows

Abstract Business process redesign is one of the most powerful ways to boost business performance and to improve customer satisfaction (Limam Mansar & Reijers, 2005). A possible approach to business process redesign is using redesign best practices. A previous study identified a set of 29 different redesign best practices (Reijers, 2003). However, little is known about the exact impact of these redesign best practices on workflow performance. This study proposes an approach that can be used to quantify the impact of a business process redesign project on all dimensions of workflow performance. The approach consists of a large set of performance measures and a simulation toolkit. It supports the quantification of the impact of the implementation of redesign best practices, in order to determine what best practice or combination of best practices leads to the most favorable effect in a specific business process. The approach is developed based on a quantification project for the parallel best practice and is validated with two other quantification projects, namely for the knockout and triage best practices.
