Absentismo nas PME'S: O caso Barcecom Têxteis S.A.

As relações laborais têm-se modificado nos últimos anos. Estas transformações trazem consigo disfuncionamentos organizacionais que têm de ser resolvidos, de forma a potenciar a competitividade das organizações e a qualidade dos seus produtos e/ou serviços. De entre os vários disfuncionamentos, encontramos o fenómeno do absentismo que, devido aos seus efeitos negativos, nomeadamente, custos elevados, baixa produtividade, baixa qualidade de serviços, desmotivação, insatisfação e mau ambiente de trabalho, tem vindo a preocupar os responsáveis da gestão. Com este trabalho procuramos compreender o fenómeno do absentismo, as suas causas e consequências, assim como as medidas e soluções para o seu combate. Para além disso, procuramos ainda enquadra-lo no contexto das PME´s. A metodologia usada assenta num estudo de caso, suportado num inquérito por questionário aos trabalhadores e numa entrevista ao responsável dos recursos humanos da Barcelcom Têxteis S.A. Da análise dos resultados obtidos, e para o caso específico, concluímos que o diálogo entre chefias e colaboradores é o fator que mais contribui para a diminuição do absentismo. E, ao contrário do que é evidenciado pelas teorias do absentismo, em concreto, a teoria de Steers & Rhodes (1990), os níveis de satisfação em relação à remuneração base, aos incentivos, ao ambiente de trabalho e a outras políticas organizacionais, não parecem influenciar as ausências ao trabalho. A falta de departamentos especializados em recursos humanos e a insensibilidade das chefias leva a que o absentismo nem sempre esteja nas prioridades dos gestores das PME´s, e que não sejam conhecidas as medidas mais usadas no seu combate. Assim, através deste estudo procuramos chamar atenção para a importância do estudo do absentismo nas PME´s.

The Audit Commission:guiding, steering and regulating local government

How does the non-executant state ensure that its agents are fulfilling their obligations to deliver nationally determined policies? In the case of elected local government in England and Wales, this function is carried out by the Audit Commission (AC) for Local Authorities and the Health Service for England and Wales. Since being established in 1983, it is the means by which local authorities are held to account by central government, both for its own purposes and on behalf of other interested stakeholders. Although the primary function of the AC is to ensure that local authorities are fulfilling their obligations, it does so by using different methods. By acting as a regulator, an independent expert, an opinion former and a mediator, the AC steers local authorities to ensure that they are compliant with the regulatory regime and are implementing legislation properly.

(Table 1) Age determination of sediments from the Campbell Plateau

Campbell Plateau occupies a key position in the southwest Pacific sector of the Southern Ocean. The plateau confines and steers the Antarctic Circumpolar Current (ACC) along its flanks, isolating the Subantarctic plateau from cold polar waters. Oxygen and carbon isotope records from Campbell Plateau cores provide new records of water mass stratification for the past 130 kyr. During glacial climes, strengthening of the Subantarctic Front (SAF) caused waters over the plateau flanks to be deeply mixed and ~3°C cooler. Waters of the plateau interior remained stratified and isolated from the cold southern waters. In the west, waters cooled markedly (~4°C) owing to reduced entrainment of Tasman Sea water. Marked cooling also occurred north of Campbell Plateau under increased entrainment of polar water by a branch of the SAF. The ACC remained along the flanks of Campbell Plateau during the last interglacial, when interior waters were stratified and warmer by ~1°C than now.

Finite domination and Novikov homology over strongly Z-graded rings

Let L be a unital Z-graded ring, and let C be a bounded chain complex of finitely generated L-modules. We give a homological characterisation of when C is homotopy equivalent to a bounded complex of finitely generated projective L0-modules, generalising known results for twisted Laurent polynomial rings. The crucial hypothesis is that L is a strongly graded ring. 

Étude des relations entre les styles cognitifs et les productions d’artistes professionnels et d’étudiants universitaires en arts visuels

Les recherches démontrent que les arts plastiques à l’école apportent des bénéfices culturels et psychocognitifs majeurs aux enfants (National Endowment for the Arts, 2012; Hoffmann Davis, 2005, 2008; Karkou et Glasman, 2004; Sylwester, 1998; Goetz Zwirn et Graham, 2005; Greene, 1995). Mais en général, plus les garçons avancent en âge au primaire, plus ils éprouvent de difficultés et démontrent un intérêt moindre que celui des filles pour les arts plastiques à l’école. Au secondaire, l’écart ne fait que s’accentuer (Savoie, Grenon et St-Pierre, 2010, 2012; Octobre, 2004; Dumais, 2002; Blaikie, Schönau et Steers, 2003). Même s’ils ne peuvent garantir la réussite de leurs élèves, les enseignants ont une influence considérable sur des variables qui affectent les apprentissages telles que le choix de matériaux didactiques, des environnements éducationnels et la variable qui nous intéresse particulièrement : La prise en compte des comportements des élèves en lien avec leurs styles cognitifs. Pour mieux les aider, notre recherche veut saisir les liens potentiels qui pourraient exister entre les styles cognitifs des individus créateurs et leurs préférences sur le plan de l’expression graphique, plus spécifiquement au regard du langage plastique. En d’autres mots, nous souhaitons fournir des marqueurs utiles à la différenciation pédagogique adaptée aux styles cognitifs (Baron-Cohen, 2005) des filles et des garçons en classe d’art. Nous empruntons des concepts délimités et mesurables qui constituent notre cadre de référence et proviennent des domaines de la psychologie cognitive et de l’enseignement des arts visuels. Notre recherche se fait auprès d’artistes professionnels et d’étudiants adultes en arts visuels, tous genres confondus. Nous mesurons chez eux, dans un premier temps, leurs styles cognitifs à l’aide du test RMET de Baron-Cohen (Ibid.). En rapport avec ces styles, nous tentons ensuite de dégager des marqueurs dans la démarche et les productions artistiques des individus. En d’autres mots, notre étude vise essentiellement à procurer des indicateurs fiables, aux chercheurs et aux enseignants en arts, quant au lien potentiel entre les styles cognitifs et le langage plastique. Ces précieux indicateurs pourront ensuite leur servir, entre autres, à la construction de modèles pédagogiques, d’environnements éducationnels ou d’activités adaptées aux styles des élèves masculins comme féminins. Au plan méthodologique, notre recherche adopte une approche quantitative, pragmatique, quasi expérimentale et exploratoire (Lefrancois, 1997; Kothari, 2004; Grawitz, 1988; Larose, Bédard, Couturier, Grenon, Lavoie, Lebrun, Morin, Savard et Theis, 2011). Notre mode d’analyse se base sur la vérification de faits observables et sur une prise de décision scientifique se servant de techniques statistiques inférentielles (Saporta, 2011; Field, 2009). Notre approche s’appuie donc sur une variable dépendante liée au style cognitif des participants et sur une vingtaine de variables indépendantes liées au langage plastique. Nos résultats démontrent qu’au moins un indicateur de style cognitif ressort significativement dans le langage plastique, soit la variation chromatique. Suite à notre question : Dans les éléments de langage plastique des créateurs en arts visuels, peut-on observer des indicateurs de styles cognitifs? La réponse s’est avérée positive et fiable sur au moins une variable : la couleur. En effet, suite à nos analyses statistiques inférentielles, la variation chromatique est ressorti comme un indicateur très significatif de style cognitif et celui qui ressort le plus de nos résultats. Nous avons clairement mesuré que les individus qui décodent moins bien les émotions chez les autres démontrent une préférence pour des variations de couleurs plutôt monochromes, alors que les individus plutôt empathiques démontrent une préférence pour des univers surtout multichromes. Nous avons mesuré une forte habileté à reconnaitre et à discriminer les émotions, autant chez nos artistes professionnels que chez nos sujets étudiants universitaires. D’autres variables analysées, comme le genre, l’éducation ou l’âge ne se sont pas avérées des indicateurs fiables de styles cognitifs particuliers.

Information Presentation Features and Comprehensibility of Hospital Report Cards: Design Analysis and Online Survey Among Users

Background: Improving the transparency of information about the quality of health care providers is one way to improve health care quality. It is assumed that Internet information steers patients toward better-performing health care providers and will motivate providers to improve quality. However, the effect of public reporting on hospital quality is still small. One of the reasons is that users find it difficult to understand the formats in which information is presented. Objective: We analyzed the presentation of risk-adjusted mortality rate (RAMR) for coronary angiography in the 10 most commonly used German public report cards to analyze the impact of information presentation features on their comprehensibility. We wanted to determine which information presentation features were utilized, were preferred by users, led to better comprehension, and had similar effects to those reported in evidence-based recommendations described in the literature. Methods: The study consisted of 5 steps: (1) identification of best-practice evidence about the presentation of information on hospital report cards; (2) selection of a single risk-adjusted quality indicator; (3) selection of a sample of designs adopted by German public report cards; (4) identification of the information presentation elements used in public reporting initiatives in Germany; and (5) an online panel completed an online questionnaire that was conducted to determine if respondents were able to identify the hospital with the lowest RAMR and if respondents’ hospital choices were associated with particular information design elements. Results: Evidence-based recommendations were made relating to the following information presentation features relevant to report cards: evaluative table with symbols, tables without symbols, bar charts, bar charts without symbols, bar charts with symbols, symbols, evaluative word labels, highlighting, order of providers, high values to indicate good performance, explicit statements of whether high or low values indicate good performance, and incomplete data (“N/A” as a value). When investigating the RAMR in a sample of 10 hospitals’ report cards, 7 of these information presentation features were identified. Of these, 5 information presentation features improved comprehensibility in a manner reported previously in literature. Conclusions: To our knowledge, this is the first study to systematically analyze the most commonly used public reporting card designs used in Germany. Best-practice evidence identified in international literature was in agreement with 5 findings about German report card designs: (1) avoid tables without symbols, (2) include bar charts with symbols, (3) state explicitly whether high or low values indicate good performance or provide a “good quality” range, (4) avoid incomplete data (N/A given as a value), and (5) rank hospitals by performance. However, these findings are preliminary and should be subject of further evaluation. The implementation of 4 of these recommendations should not present insurmountable obstacles. However, ranking hospitals by performance may present substantial difficulties.

Supplementation of cattle fed tropical grasses with microalgae increases microbial protein production and average daily gain

A series of 3 experiments were conducted to evaluate the use of microalgae as supplements for ruminants consuming low-CP tropical grasses. In Exp. 1, the chemical composition and in vitro protein degradability of 9 algae species and 4 protein supplements were determined. In Exp. 2, rumen function and microbial protein (MCP) production were determined in Bos indicus steers fed speargrass hay alone or supplemented with Spirulina platensis, Chlorella pyrenoidosa, Dunaliella salina, or cottonseed meal (CSM). In Exp. 3, DMI and ADG were determined in B. indicus steers fed speargrass hay alone or supplemented with increasing amounts of NPN (urea combined with ammonia sulfate), CSM, or S. platensis. In Exp. 1, the CP content of S. platensis and C. pyrenoidosa (675 and 580 g/kg DM) was highest among the algae species and higher than the other protein supplements evaluated, and Schizochytrium sp. had the highest crude lipid (CL) content (198 g/kg DM). In Exp. 2, S. platensis supplementation increased speargrass hay intake, the efficiency of MCP production, the fractional outflow rate of digesta from the rumen, the concentration of NH3N, and the molar proportion of branched-chain fatty acids in the rumen fluid of steers above all other treatments. Dunaliella salina acceptance by steers was low and this resulted in no significant difference to unsupplemented steers for all parameters measured for this algae supplement. In Exp. 3, ADG linearly increased with increasing supplementary N intake from both S. platensis and NPN, with no difference between the 2 supplements. In contrast, ADG quadratically increased with increasing supplementary N intake from CSM. It was concluded that S. platensis and C. pyrenoidosa may potentially be used as protein sources for cattle grazing low-CP pastures.

Efficiency of rumen microbial protein synthesis in cattle grazing tropical pastures as estimated by a novel technique

The efficiency of microbial protein synthesis (EMPS) in cattle grazing a range of tropical pasture types was examined using a new method of intra-jugular infusion of CrEDTA to estimate urinary excretion of purine derivatives (PD). Seven pasture types were studied in south-east Queensland, Australia, over a 13-month period. These included native tropical grass (C4) pasture (major species Heteropogon contortus and Bothriochloa bladhii) studied in the early wet, the wet/dry transition and the dry season; introduced tropical grass (C4) pasture (Bothriochloa insculpta) in the mid wet season; two introduced tropical legume species (C3), (Lablab purpureus and Clitoria ternatea); and the temperate grass (C3) pasture, ryegrass (Lolium multiflorum). There was a large range in EMPS across pasture types: 26-209 g microbial crude protein (MCP)/kg digestible organic matter intake (DOMI). Estimated rumen degradable protein (RDP) supply (42-525 g/kg DOMI) was the major factor associated with EMPS across the range of pasture types studied. EMPS in steers grazing all tropical grass pastures was low (<130 g/kg DOMI) and limited by RDP supply. Negative linear relationships (P<0.05) between EMPS and both neutral detergent fibre (NDF) and acid detergent fibre (ADF) concentrations in extrusa were evident. However, non-fibre carbohydrate in extrusa, total non-structural carbohydrate concentration in plucked pasture leaf, rumen fluid and particle dilution rate, protozoal concentration in rumen fluid and rumen fluid pH were not correlated with EMPS. It was concluded that EMPS was well below 130 g MCP/kg DOMI when cattle grazed unfertilised, tropical grass pastures in south-east Queensland and that RDP was the primary limiting nutrient. High EMPS was associated with very high RDP, vastly in excess of RDP requirements by microbes

Validation of single photon absorptiometry for on-farm measurement of density and mineral content of tail bone in cattle

A validation study examined the accuracy of a purpose-built single photon absorptiometry (SPA) instrument for making on-farm in vivo measurements of bone mineral density (BMD) in tail bones of cattle. In vivo measurements were made at the proximal end of the ninth coccygeal vertebra (Cy9) in steers of two age groups (each n = 10) in adequate or low phosphorus status. The tails of the steers were then resected and the BMD of the Cy9 bone was measured in the laboratory with SPA on the resected tails and then with established laboratory procedures on defleshed bone. Specific gravity and ash density were measured on the isolated Cy9 vertebrae and on 5-mm2 dorso-ventral cores of bone cut from each defleshed Cy9. Calculated BMD determined by SPA required a measure of tail bone thickness and this was estimated as a fraction of total tail thickness. Actual tail bone thickness was also measured on the isolated Cy9 vertebrae. The accuracy of measurement of BMD by SPA was evaluated by comparison with the ash density of the bone cores measured in the laboratory. In vivo SPA measurements of BMD were closely correlated with laboratory measurements of core ash density (r = 0.92). Ash density and specific gravity of cores, and all SPA measures of BMD, were affected by phosphorus status of the steers, but the effect of steer age was only significant (P < 0.05) for steers in adequate phosphorus status. The accuracy of SPA to determine BMD of tail bone may be improved by reducing error associated with in vivo estimation of tail bone thickness, and also by adjusting for displacement of soft tissue by bone mineral. In conclusion a purpose-built SPA instrument could be used to make on-farm sequential non-invasive in vivo measurements of the BMD of tailbone in cattle with accuracy acceptable for many animal studies.

An evaluation of carbon offset supplementation options for beef production systems on coastal speargrass in central Queensland, Australia

In 2014, the Australian Government implemented the Emissions Reduction Fund to offer incentives for businesses to reduce greenhouse gas (GHG) emissions by following approved methods. Beef cattle businesses in northern Australia can participate by applying the 'reducing GHG emissions by feeding nitrates to beef cattle' methodology and the 'beef cattle herd management' methods. The nitrate (NO3) method requires that each baseline area must demonstrate a history of urea use. Projects earn Australian carbon credit units (ACCU) for reducing enteric methane emissions by substituting NO3 for urea at the same amount of fed nitrogen. NO3 must be fed in the form of a lick block because most operations do not have labour or equipment to manage daily supplementation. NO3 concentrations, after a 2-week adaptation period, must not exceed 50 g NO3/adult animal equivalent per day or 7 g NO3/kg dry matter intake per day to reduce the risk of NO3 toxicity. There is also a 'beef cattle herd management' method, approved in 2015, that covers activities that improve the herd emission intensity (emissions per unit of product sold) through change in the diet or management. The present study was conducted to compare the required ACCU or supplement prices for a 2% return on capital when feeding a low or high supplement concentration to breeding stock of either (1) urea, (2) three different forms of NO3 or (3) cottonseed meal (CSM), at N concentrations equivalent to 25 or 50 g urea/animal equivalent, to fasten steer entry to a feedlot (backgrounding), in a typical breeder herd on the coastal speargrass land types in central Queensland. Monte Carlo simulations were run using the software @risk, with probability functions used for (1) urea, NO3 and CSM prices, (2) GHG mitigation, (3) livestock prices and (4) carbon price. Increasing the weight of steers at a set turnoff month by feeding CSM was found to be the most cost-effective option, with or without including the offset income. The required ACCU prices for a 2% return on capital were an order of magnitude higher than were indicative carbon prices in 2015 for the three forms of NO3. The likely costs of participating in ERF projects would reduce the return on capital for all mitigation options. © CSIRO 2016.

The aporetics of religious diversity

My thesis situates itself within the field of the Philosophy of Worldviews. Specifically, it aims to address the normative question of what the task should be of such a philosophy when faced with the problem of conflicting beliefs between religious worldviews. To answer this question, I turn to the procedure of aporetical analysis, in short, aporetics. Firstly, aporetics offers a distinct method of consistency restoration within inconsistent sets on the basis of thesis rejection and thesis modification. Secondly, aporetics leads to an understanding of the availability of aporetic exits on the basis of epistemic criteria. On the one hand, this leads us to opt for an orientational monism/pluralism, which steers the middle course between the epistemic stances of exclusivism and pluralism. On the other hand, it allows us to identify epistemic criteria for worldview acquisition on the basis of three distinct superclasses. These superclasses can be derived from Jürgen Habermas' validity claims, and applied to the self-understanding of contemporary theories of religion.

Aditivos químicos e biológicos na ensilagem de cana-de-açúcar: 1. composição química das silagens, ingestão, digestibilidade e comportamento ingestivo

Avaliou-se o efeito da inclusão de aditivos na ensilagem de cana-de-açúcar (Saccharum officinarum L.) sobre a composição químico-bromatológica das silagens, o comportamento ingestivo, o consumo voluntário e a digestibilidade em bovinos de corte. Utilizaram-se cinco novilhos da raça Nelore providos de cânula ruminal, alocados em delineamento quadrado latino 5 ´ 5 e alimentados com dietas com 65% de volumoso na MS. Foram avaliadas cinco silagens (base úmida): controle - cana-de-açúcar sem aditivos; uréia - cana-de-açúcar + 0,5% uréia; benzoato - cana-de-açúcar + 0,1% de benzoato de sódio; LP - cana-de-açúcar inoculada com Lactobacillus plantarum (1 ´ 10(6) ufc/g MV); LB - cana-de-açúcar inoculada com L. buchneri (3,6 ´ 10(5) ufc/g forragem). A forragem foi armazenada em silos do tipo poço por 90 dias antes do fornecimento aos animais. A composição químico-bromatológica da cana-de-açúcar foi alterada após a ensilagem, em relação à cana-de-açúcar original, com redução no teor de carboidratos solúveis e na digestibilidade in vitro e elevação relativa nos teores de FDN e FDA. Os teores de etanol (0,30% da MS) e ácidos orgânicos (0,99% de ácido lático e 2,31% de acético) foram baixos e semelhantes entre as silagens. Os aditivos aplicados na ensilagem não promoveram alterações no consumo e na digestibilidade aparente da MS (7,2 kg/dia e 63,6%, respectivamente). O comportamento ingestivo dos animais também não foi alterado, com tempos médios de 230,6; 519,6 e 672,8 minutos/dia despendidos com ingestão de ração, ruminação e ócio, respectivamente. Os aditivos acrescidos à cana-de-açúcar promoveram pequenas alterações na maioria das variáveis avaliadas.

Aditivos químicos ou biológicos na ensilagem de cana-de-açúcar: 2. parâmetros ruminais e degradabilidade da matéria seca e das frações fibrosas

Objetivou-se avaliar o efeito da inclusão de aditivos na ensilagem de cana-de-açúcar (Saccharum officinarum L.) sobre a degradação de MS e de componentes da parede celular e sobre os parâmetros de fermentação ruminal em bovinos alimentados com dietas contendo essas silagens. Utilizaram-se cinco novilhos da raça Nelore providos de cânula ruminal, alocados em delineamento quadrado latino 5 ´ 5 e alimentados com dietas com 65% de volumoso (%) MS. Foram avaliadas cinco silagens (base úmida): controle - cana-de-açúcar, sem aditivos; uréia - cana-de-açúcar + 0,5% ureia; benzoato - cana-de-açúcar + 0,1% de benzoato de sódio; LP - cana-de-açúcar inoculada com Lactobacillus plantarum (1 ´ 10(6) ufc/g MV); LB - cana-de-açúcar inoculada com L. buchneri (3,6 ´ 10(5) ufc/g forragem). A forragem foi armazenada em silos do tipo poço por 90 dias antes do fornecimento aos animais. Os parâmetros ruminais foram afetados de forma moderada pelas silagens e tiveram forte efeito do horário de coleta de amostras. As concentrações molares médias dos ácidos acético, propiônico e butírico foram de 60,9; 19,3 e 10,2 mM, respectivamente. O ambiente ruminal proporcionado por dietas formuladas com silagens de cana-de-açúcar foi satisfatório e similar ao tradicionalmente observado em dietas contendo cana. O uso de aditivos na ensilagem influenciou, de forma não-significativa, a degradabilidade ruminal da MS e da MO, mas não alterou a degradabilidade ruminal da fração fibrosa. Os aditivos aplicados à cana-de-açúcar resultaram em pequenas alterações na maior parte das variáveis avaliadas. Apesar de a degradabilidade ruminal das silagens ter sido pouco afetada pelo uso de aditivos, os valores observados foram próximos aos observados para a cana-de-açúcar in natura.

Adaptación de instrumentos para la evaluación de aspectos organizacionales en ONG's

En los últimos años se ha evidenciado que las actitudes hacia la organización o hacia la actividad en sí juegan un importante papel en la explicación de la continuidad de los voluntarios en las organizaciones. A pesar de ello, aún no se cuenta con instrumentos de evaluación adecuados que permitan un estudio más exhaustivo de estas actitudes en los voluntarios. En este artículo se presenta la adaptación a este ámbito de algunos instrumentos habitualmente utilizados para estudiar dichas actitudes en personal remunerado. El Organizational Commitment Questionarie (OCQ) de Mowday, Steers y Porter, el Job Involvement de Lodahl y Kejner y el Job Diagnostic Survey de Hackman y Oldham adaptados a la población voluntaria se aplicaron a 419 voluntarios que realizaban muy diferentes actividades. El análisis de algunas de las propiedades psicométricas de estos instrumentos muestra que tanto el Organizational Commitment Questionarie como el Job Diagnostic Survey parecen adaptarse bien a las peculiaridades del voluntariado, en cambio, con el Job Involvement se encuentran resultados que permiten cuestionar su validez y adecuación, por lo que será necesario desarrollar más investigaciones para su rechazo o su afirmación definitiva en el estudio del voluntariado.

Potential mitigation of midwest grass-finished beef production emissions with soil carbon sequestration in the United States of America

Beef production can be environmentally detrimental due in large part to associated enteric methane (CH4) production, which contributes to climate change. However, beef production in well-managed grazing systems can aid in soil carbon sequestration (SCS), which is often ignored when assessing beef production impacts on climate change. To estimate the carbon footprint and climate change mitigation potential of upper Midwest grass-finished beef production systems, we conducted a partial life cycle assessment (LCA) comparing two grazing management strategies: 1) a non-irrigated, lightly-stocked (1.0 AU/ha), high-density (100,000 kg LW/ha) system (MOB) and 2) an irrigated, heavily-stocked (2.5 AU/ha), low-density (30,000 kg LW/ha) system (IRG). In each system, April-born steers were weaned in November, winter-backgrounded for 6 months and grazed until their endpoint the following November, with average slaughter age of 19 months and a 295 kg hot carcass weight. As the basis for the LCA, we used two years of data from Lake City Research Center, Lake City, MI. We included greenhouse gas (GHG) emissions associated with enteric CH4, soil N2O and CH4 fluxes, alfalfa and mineral supplementation, and farm energy use. We also generated results from the LCA using the enteric emissions equations of the Intergovernmental Panel on Climate Change (IPCC). We evaluated a range of potential rates of soil carbon (C) loss or gain of up to 3 Mg C ha-1 yr-1. Enteric CH4 had the largest impact on total emissions, but this varied by grazing system. Enteric CH4 composed 62 and 66% of emissions for IRG and MOB, respectively, on a land basis. Both MOB and IRG were net GHG sources when SCS was not considered. Our partial LCA indicated that when SCS potential was included, each grazing strategy could be an overall sink. Sensitivity analyses indicated that soil in the MOB and IRG systems would need to sequester 1 and 2 Mg C ha-1 yr-1 for a net zero GHG footprint, respectively. IPCC model estimates for enteric CH4 were similar to field estimates for the MOB system, but were higher for the IRG system, suggesting that 0.62 Mg C ha-1 yr-1 greater SCS would be needed to offset the animal emissions in this case.
