Strategic management accounting: definitions and dimensions

The purposes of this paper are twofold: firstly it aims to discuss prior definitions of strategic management accounting (SMA) in order to understand the main purposes and the scope of SMA; secondly the management accountant’s participation in the strategic decision-making and SMA practices are discussed. The SMA literature review shows us that there is no consensus in the SMA definition. However, there is some common elements in the SMA definitions, such as: i) a development of management accounting with a strategic orientation; ii) an external orientation (outward-looking orientation); and, iii) an orientation for future (forward-looking orientation). In addition, SMA adopts both financial and non-financial measurement typologies and an orientation to internal resources and organizational capabilities (intellectual capital). There is also some consensus on the main purpose. SMA must cooperate and provide strategic information for the strategic management, marketing, and other managerial functions. The purpose is to create and achieve competitive advantages and enhance organizational performance. To accomplish this goal SMA considers two dimensions related with the management accountant’s participation in the strategic decisionmaking process and a set of SMA practices. Therefore, this paper contributes to a better understanding of the concept and scope of SMA and its two dimensions. In this sense, it assists practitioners and researchers to understand, adopt, use, and research the SMA.info:eu-repo/semantics/publishedVersio

Contributos da NCRF 17 para o cumprimento do objetivo das demonstrações financeiras nas empresas do setor? Análise e reflexão a partir das caraterísticas da envolvente

O setor agrícola integra atualmente grandes explorações de âmbito transnacional, ainda que em Portugal, e também no espaço europeu, estas entidades sejam maioritariamente pequenas. O processo de transformação biológica, enquanto elemento diferenciador nestas atividades, pressupõe que a medição dos ativos biológicos se faça a partir dos seus ciclos produtivos. A aplicação do Justo Valor (JV) é apresentada pelo normativo como o caminho preferencial, ainda que sejam já vários os trabalhos que lhe apontam limitações e pouca aderência à realidade portuguesa. Neste sentido, e com base numa metodologia qualitativa, aprofundou-se a discussão sobre as bases de mensuração destes ativos, de modo a que sejam vistas à luz das idiossincrasias do setor e daquelas que são as principais caraterísticas da envolvente. Concluiu-se, ainda que o espírito da norma não levante dúvidas de interpretação, apontando claramente para a aplicação do JV, que a sua aplicação prática não é tão simples e linear.info:eu-repo/semantics/publishedVersio

Factorial analysis of the trihalomethanes formation in water disinfection using chlorine

The factors that affect trihalomethane (THM) (chloroform, bromodichloromethane, chlorodibromomethane and bromoform) formation from the chlorination of aqueous solutions of hydrophobic fulvic acids (FA) were investigated in a prototype laboratorial simulation using factorial analysis. This strategy involved a fractional factorial design (16 plus 5 center experiments) of five factors (fulvic acids concentration, chlorine dose, temperature, pH and bromide concentration) and a Box Behnken design (12 plus 3 center experiments) for the detailed analysis of three factors (FA concentration, chlorine dose and temperature). The concentration ofTHMwas determined by headspace analysis by GC–ECD. The most significant factors that affect the four THM productions were the following: chloroform—FA concentration and temperature; bromodichloromethane—FA concentration and chlorine dose; chlorodibromomethane—chlorine dose; and, bromoform—chlorine dose and bromide concentration. Moreover, linear models were obtained for the four THM concentrations in the disinfection solution as function of the FA concentration, chlorine dose and temperature, and it was observed that the complexity of the models (number of significant factors and interactions) increased with increasing bromine atoms in the THM. Also, this study shows that reducing the FA concentration the relative amount of bromated THM increases

Multivariate analysis of the water quality variation in the Serra da Estrela (Portugal) Natural Park as a consequence of road deicing with salt.

The concentration of some anions (Cl, F, NO3, and SO4), cations (Na, K, Ca, and Mg), pH and conductivity was determined in seven sampling points in the Serra da Estrela Mountains (Portugal) to verify if the application of road deicing with salt provokes impact in the water quality. Multivariate chemometric data analysis techniques of clustering and factor analysis were used. Preliminary analysis shows an overall conductivity increase in late spring and a decrease in late summer. A strong association between sodium chloride and the conductivity was observed by cluster analysis. Factor analysis supports the previous results and shows that the variation of the concentration of sodium chloride is the main source of the variance of the data along the year. In conclusion, the spreading of salt during the winter creates a local and seasonal impact on the water quality

Application of a thermolysis capacity test for dry and lactating cows

The heat stress has negative effects on animal comfort and productivity. Genetic progress in milk production is related closely to an increase in metabolic heat increment, which makes cows more affected by heat stress. Individual thermotolerance can be an important tool in genetic selection. The study aimed to validate a new proposal for assessing the ability of heat loss after sun exposure in cows and its application in dry and lactating cows kept or not on thermal comfort condition. The test consists in three days of sun exposure for one hour followed by one hour rest in the shade to determine the individual thermolysis capacity (TC) by the variables rectal temperature, body surface temperature, internal tail base temperature, respiratory rate, plasma cortisol and IGF-I. In the new proposal these physiological variables were measured before sun exposure, after 50 min in the sun and after one hour in the shade (T0, T1 and T2 consecutively). The test in which this new test was adapted lacked T1.The three day test was applied with similar meteorological variables as black globe temperature of 48.1°C (1.32), air temperature of 31.7°C (0.92) and relative humidity of 39.5% (3.38). The differences between dry and lactating cows were measured in 28 animals divided into two experimental groups housed in free-stall with and without evaporative cooling system (mist and fans). The animals remained at the facility for seven months (from spring to summer) then after they were subjected to heat stress and the TC (10-[(T1-T0)-(T2-T1)]) was determined. There was no difference between the TC of dry and lactating cows (P>0.05), but respiratory rate and IGF-I were greater and body surface was lower in dry cows during sun exposure (P0.05). The thermolysis capacity test was validated and can be used for either dry or lactating cows. Milk production did not influence the thermoregulatory responses of Holstein cows, but when lactating and kept in cooling system they showed better thermolysis capacity index

Reactivity in ewes submitted to invasive and non-invasive techniques of samples collections

The first-time experience of a procedure or with a person should be as positive as possible. If a procedure is very aversive or painful at first contact, it can be difficult to persuade the animal to return to the local where this occurred. For this reason it is important to develop a strategy in experimental and routine activities, taking into account that sheep has often reactive temperament. This study aims to evaluate the possible decreased of the reactivity in sheep across the prior presentation of invasive and non-invasive techniques for collecting saliva and blood samples for cortisol analysis and transepidermal water loss through the use of Vapometer®. Saliva was collected using Sallivetes® and blood was taken from the jugular vein in heparinized tubes, placed on ice, and then centrifuged at 4 °C and 3,000 for 15 min. The tubes containing serum were stored at −20 °C until CORT and IGF-I determination using an enzyme immunoassay kit (Diagnostic Systems Laboratory, Webster, TX). The collection of transepidermal water loss (TEWL) was performed using a Vapometer ® (Dolphin, Finland) device. In the three techniques the ewes were always contained by the same person for the time necessary to collect the variable. To take saliva samples the animals were contained during 2 minutes, for blood samples during 1 minute and for TEWL during 30 seconds. The test consists of six data collections performed with increasing intervals between days, checking the possible adaptation of the animal management factors. The first interval was 2 days and after 3 days, then after 4 days, and the next was 7 days and again 7 days, totaling 24 days of experiment. Before sampling saliva, blood or TEWL the reactivity of the ewes was analyzed by a composite score scale when animals were inside the chute. The composite score (CS) is a combination of the scores of: entrance (1 to 4), respiratory rate (1 to 4), vocalization (0 or 1), movement (1 to 4) and flight speed (1 to 4). After the chute a score of containment (1 to 4) was attributed by the same person, which had contained the animal. The experimental unit was each animal and the average of the observations in each sheep was used for the statistical analysis. The observed data of transepidermal water loss, salivary cortisol and serum cortisol were subjected to analysis of variance, with the days and the groups as fixed effect. In case of significant results (P<0.05) it was adopted Tukey-Kramer Test as the procedure for multiple comparisons. Cortisol decreased for saliva and blood groups during the experiment days (P<0.05), showing habituation of the animals to the management. In the same way, TEWL had the highest mean value on day 1, and decreased afterwards (P<0.05). The score of containment was lower for the TEWL group compared to the other two groups (P<0.05), however the higher value was observed on day 5, seven days after a sampling (P<0.05). The score of containment of saliva and blood groups decrease in day 2, but return to increase in the next sampling day (P<0.05). The CS was higher for saliva group (P<0.05). On day 5 CS increased for blood group, but decreased for TEWL (P<0.05). The invasive techniques (saliva and blood) increased the reactivity of sheep before and after retention. Sheep are reactive animals therefore need a more gentle handling during the experiment with invasive samples

A neoproterozoic age for the chromitite and gabbro of the Tapo Ultramafic Massif, Eastern Cordillera, Central Peru, and its tectonic implications

The ultramafic-mafic rocks of the Tapo Complex are exposed in the Eastern Cordillera of the Central Peruvian Andes. This complex is composed of serpentinised peridotites and metabasites with some podiform chromitite lenses and chromite disseminations and overlies the sandstones, conglomerates, and tuffs of the Carboniferous Ambo Group. The metagabbros and amphibolites showa tholeiitic affiliation and a flat REE spider diagram, with a slight LREE depletion and a positive Eu anomaly suggesting magmatic accumulation of plagioclase, in an ocean ridge or ocean island environment. Sm-Nd isotopic analyses were performed on chromite as well as on whole rock from the gabbro. All samples yielded an Sm-Nd isochrone age of718 ± 47 Ma with an initial 143Nd/l44Nd of0.51213 ± 0.00005. The Nd (718 Ma) values calculated for both chromite and gabbro are in close agreement, around 8.0, implying that they were formed at the same time from the same mantelic magma source. Furthermore a K-Ar age on amphibole of 448 ± 26 Ma was obtained, interpreted as the cooling age of a younger orogenic event. These rocks represent slices of oceanic crust (from a dismembered ophiolitic complex), metamorphosed and later overthrust on upper Palaeozoic continental formations

How likely are adaptive responses to mitigate the threats of climate change for amphibians globally?

Whether species are capable of adapting to rapid shifts in climate raises considerable interest. Analyses based on niche models often assume niche conservatism and equilibrium with climate, implying that species will persist only in regions where future climatic conditions match their current conditions and that they will colonize these regions promptly. However, species may adapt to changing climate and persist where future climates differ from their current optimum. Here, we provide a first macroecological generalization to the approach of evolutionary rescue, by comparing the expected shift in mean temperature within the geographic range of 7193 species of amphibians worldwide, under alternative warming scenarios. Expected evolutionary change is expressed in units of standard deviations of mean temperature, per generation (Haldanes) and compared with theoretical models defining the maximum sustainable evolutionary rates (MSER) for each species. For the pessimistic emission scenario RCP8.5, shifts in mean temperature vary between near-zero and 6°C within the geographic ranges for most species, with a median equal to 3.75°C. The probability of evolutionary rescue in temperature peaks is higher than 0.05 for about 55% of the species and higher than 0.95 for only 12% of the species. Therefore, the predicted shift in mean temperature would be too extreme to deal with for almost half of the species. When evolutionary plasticity is incorporated, this scenario becomes more optimistic, with about 44% of the species being likely to shift their thermal peaks tracking future warming. These figures are not random in geographical space: evolutionary rescue would be unlikely in the tropics, especially in South America (Amazonia), parts of Africa, Indonesia, and in the Mediterranean region. Given the uncertainty in demographic and genetic parameters for species’ responses to climate change, we caution that it remains difficult to assess the realism of the macroecological generalization. In any case, it may be precautionary to assume that our results are not liberal, showing low probability of adaptation for most of the species and thus that the persistence of populations by evolutionary rescue may, in general, be unlikely in the long term

Health promoting potential of herbal teas and tinctures from <i>Artemisia campestris</i> subsp. <i>maritima</i>: from traditional remedies to prospective products

This work explored the biotechnological potential of the medicinal halophyte Artemisia campestris subsp. maritima (dune wormwood) as a source of health promoting commodities. For that purpose, infusions, decoctions and tinctures were prepared from roots and aerial-organs and evaluated for in vitro antioxidant, anti-diabetic and tyrosinase-inhibitory potential, and also for polyphenolic and mineral contents and toxicity. The dune wormwood extracts had high polyphenolic content and several phenolics were identified by ultra-high performance liquid chromatography–photodiode array–mass-spectrometry (UHPLC-PDA-MS). The main compounds were quinic, chlorogenic and caffeic acids, coumarin sulfates and dicaffeoylquinic acids; several of the identified phytoconstituents are here firstly reported in this A. campestris subspecies. Results obtained with this plant’s extracts point to nutritional applications as mineral supplementary source, safe for human consumption, as suggested by the moderate to low toxicity of the extracts towards mammalian cell lines. The dune wormwood extracts had in general high antioxidant activity and also the capacity to inhibit α-glucosidase and tyrosinase. In summary, dune wormwood extracts are a significant source of polyphenolic and mineral constituents, antioxidants and α-glucosidase and tyrosinase inhibitors, and thus, relevant for different commercial segments like the pharmaceutical, cosmetic and/or food industries
