Metabolic evaluation of dairy cows submitted to three different strategies to decrease the effects of negative energy balance in early postpartum

In early lactation dairy cattle suffer metabolic alterations caused by negative energy balance, which predisposes to fatty liver and ketosis. The aim of this study was to evaluate the metabolic condition of high yielding dairy cows subjected to three treatments for preventing severe lipomobilization and ketosis in early lactation. Fifty four multiparous Holstein cows yielding >30 L/day were divided into four groups: control (CN= no treatment), glucose precursor (PG= propylene-glycol), hepatic protector (Mp= Mercepton®), and energy supplement with salts of linolenic and linoleic faty acids (Mg-E= Megalac-E®). Treatments were administrated randomly at moment of calving until 8 weeks postpartum. Blood samples were collected on days 1, 7, 14, 21, 28, 35, 42 and 49 postpartum. Body condition score (BCS) was evaluated at the same periods and milk yield was recorded at 2nd, 4th, 5th, 6th, 7th, and 8th weeks of lactation. Concentrations of non-esterified fatty acids (NEFA), albumin, AST, ß-hydroxybutyrate (BHBA), cholesterol, glucose, total protein, urea and triglycerides were analyzed in blood samples. Cut-off points for subclinical ketosis were defined when BHBA >1.4 mmol/L and NEFA >0.7 mmol/L. General occurrence of subclinical ketosis was 24% during the period. An ascendant curve of cholesterol and glucose was observed from the 1st to the 8th week of lactation, while any tendency was observed with BHBA and NEFA, although differences among treatments were detected (p<0.05). BCS decreased from a mean of 3.85 at 1st week to 2.53 at 8th week of lactation (p=0.001). Milk yield was higher in the Mg-E group compared with the other treatment groups (p<0.05) Compared with the CN group, the treatments with Mp and PG did not show significant differences in blood biochemistry and milk yield. Cows receiving PG and Mg-E showed higher values of BHBA and NEFA (P<0.05), indicating accentuated lipomobilization. Supplementation with Mg-E also resulted in significant higher concentrations of cholesterol, BHBA, urea, AST and lower values of glycemia. This performance may be explained by the highest milk yield observed with this treatment. Treatments with PG and Mp did not improve milk yield, compared with control cows, but did not show metabolic evidence of ketosis, fat mobilization or fatty liver. These results suggest that treatment with Mg-E improves milk production but induces a higher negative energy balance leading to moderated lipomobilization and ketone bodies production, increasing the risk of fatty liver.

Acid-base balance of dairy cows and its relationship with alcoholic stability and mineral composition of milk

This study aimed to associate the occurrence of acid-base disorders with the alcoholic stability of milk from animals in the field, and to evaluate differences between the mineral composition of milk that was both stable and unstable in alcohol. The sample comprised 96 dairy cows, where the milk and blood of each corresponding animal was collected. The mineral composition of stable and unstable milk in alcohol was different and may be related to acid-base disturbances. The average amount of phosphate was lower in the milk that was unstable in alcohol, while potassium was greater. Frequency of the alcoholically unstable milk cases was higher in the cows with acid-base disturbances. Respiratory alkalosis was the disorder that was most observed.

En vårdvetenskaplig syntes mellan vårdandets ethos och vårdintensitet

This is a study in the field of caring science. The kinds of knowledge expansion and theoretical formation outlined in this thesis have a hypothetic-deductive design. The synthesizer of caring science between caring ethos and nursing intensity evolves through a hermeneutic movement between understanding and interpretation, in the dialectic tension between thesis and antithesis. The study had three main aims with corresponding research questions. The first aim was to deepen the understanding of caring ethos within the care of older people from the perspective of caring science. The second aim was to deepen the understanding of nursing intensity within the care of older people, again from the perspective of caring science. The third aim of the study was to create a theoretical model describing the synthesizer between the caring ethos and nursing intensity. The synthesizer of caring science between caring ethos and nursing intensity took place in a process of creativity, which resulted in six new patterns of interpretation. Good care is in constant movement and tension between the ethical and the unethical. In order to guarantee the older person of the future dignity, a caring community, and integrity in care, there is a need for an awareness of and responsibility for those entities than can become ethical problems and dilemmas. The model that describes the synthesizer between caring ethos and nursing intensity, consist of four cornerstones such as caring ethics, wishes and anticipations, an ethical manner in words and action, and ethical leadership. Good care based on the values dignity, a caring community, safety, and integrity, receive their legitimacy through ethical awareness, and consent among caregivers. Ethical awareness deepens the understanding of wishes and expectations that may arise as special needs. Care thus requires an awareness of the balance between the patient’s care need and optimal level of nursing intensity. An ethical leadership considers the needs of the patient and accepts nothing but a work situation where optimal nursing intensity and optimal resource allocation makes good care possible.

Sport-based corporate social responsibility in European professional football

In the past few decades, sport has become a major business with remarkable international reach. As part of the commercial sector of sport, professional sport is said to be intrinsically different from other businesses due to its unique characteristics, such as the peculiar economics and the intense loyalty of fans. Simultaneously with the growing business aspect, sport continues to have great social and cultural impacts on our society. Sport has also become an increasingly popular means of attending social problems due to its alleged suitability for such purposes and its popular appeal. A great number of actors in the professional sport industry have long been involved in socially responsible activities, many of which have been sport-related. While Corporate Social Responsibility (CSR) has been extensively studied in general, its role in the professional sport industry has received less attention in the academic research until recently. It has been argued that due to the unique characteristics of professional sport, CSR should also be studied in this particular context. The objective of this study was to contribute to filling the research gap and increase the understanding of CSR in the context of professional sport by examining sport-related CSR realized by professional football clubs in Europe. The theoretical part of this study leaned on previous literature about using sport as a means of attending social issues and the role of CSR in professional sport industry. The empirical part of the study was carried out through web site analyses and interviews. The clubs to be examined were chosen by using purposive sampling technique and taking into consideration the accessibility and suitability of information the clubs could offer. The method used for analyzing the data was qualitative content analysis. The empirical findings were largely in line with the theoretical framework of the study. The sportrelated CSR of the clubs was concentrated on teaching the participants diverse skills and values, improving their health, encouraging social inclusion, supporting disabled people, and promoting overall participation in sport. The clubs also emphasized the importance of local communities as targets of their CSR. CSR had been an integral part of the clubs’ activities from the beginning, but there were remarkable differences between large and small clubs in terms of structured organization and realization of their CSR. Measuring and evaluation of CSR appeared to be a challenge for most clubs regardless of their size and resources. The motives for the clubs to engage in CSR seemed to be related to the clubs’ values or to their stakeholders’ interests. In general, the clubs’ CSR went beyond what the society is likely to expect from them in legal or ethical sense.

Analysis of corporate social responsibility (CSR) performance and financial performance of selected mining companies

The global concern about sustainability has been growing and the mining industry is questioned about its environmental and social performance. Corporate social responsibility (CSR) is an important issue for the extractive industries. The main objective of this study was to investigate the relationship between CSR performance and financial performance of selected mining companies. The study was conducted by identifying and comparing a selection of available CSR performance indicators with financial performance indicators. Based on the result of the study, the relationship between CSR performance and financial performance is unclear for the selected group of companies. The result is mixed and no industry specific realistic way to measure CSR performance uniformly is available. The result as a whole is contradictory and varies at company level as well as based on the selected indicators. The result of this study confirms that the relationship between CSR performance and financial performance is complicated and difficult to determine. As an outcome, evaluation of benefits of CSR in the mining sector could better be analyzed based on different attributes.

Corporate Social Responsibility and Shipping Views of Baltic Sea Shipping Companies on the Benefits of Responsibility

The safety of shipping operations in the Baltic Sea is an extensively studied issue due to the density of traffic and the ecological sensitivity of the area. The focus has, however, mainly been on ship technology or on traffic control measures and the operative safety aspect of shipping is in a minor position in maritime safety studies and is lacking in terms of solutions. Self-regulatory and voluntary measures could be effective ways to improve the operational safety of shipping. Corporate social responsibility, or CSR, is one example of a voluntary measure that the shipping companies can take. CSR can enhance maritime safety and improve the shipping companies’ competitiveness. The aim of this study is to increase the knowledge of CSR in the maritime sector and study its applicability and benefits to the shipping companies. The research comprises of a theory part and a questionnaire study, which examine the significance of corporate social responsibility in shipping companies’ maritime safety and competitiveness. The aim of the questionnaire study is to find out how corporate social responsibility is implemented in the shipping companies. According to the literature review, responsible actions can produce financial and time costs, but due to these actions cost savings in the form of learning and increased efficiency can be achieved. Responsible actions can also produce concrete improvements and a reputation of responsibility that can lead to both cost savings and increase in the company’s income. CSR is recognised as having real business benefits in terms of attracting customers and high-quality employees. In shipping, CSR usually focuses on environmental issues. Environmental social responsibility in shipping is mainly motivated by the need to comply with existing and forthcoming regulation. Shipping companies engage in CSR to gain competitive advantage and to increase maritime safety. The social aspects of CSR take into account the well-being and skills of the employees, corporation and other stakeholders of the company. The questionnaire study revealed that the most common CSR measures in shipping companies are environmental measures, and that environmental concerns are considered to be the most important reason to engage in CSR. From the preliminary question about the concept of CSR it can also be seen that safety issues are commonly considered to be a part of CSR and safety gains are the second most important reason to engage in CSR. From the questionnaire, it can also be extrapolated that gaining a better reputation is one of the most important reasons to engage in CSR in the first place. For example, the main economic benefit was seen to be the increase of customer numbers as a result of a better reputation. Based on the study, it would seem that companies are starting to realise that they might gain competitive advantage and be favoured as shippers if they engage in sustainable, responsible operations and present themselves as “green”.

Assimilate partitioning in leaves of the raffinose-storing herb Lamium album L.: the effects of altering source-sink balance

In Lamium album, sucrose and raffinose-family oligosaccharides are the major products of photosynthesis that are stored in leaves. Using gas analysis and 14CO2 feeding, we compared photosynthesis and the partitioning of recently-fixed carbon in plants where sink activity was lowered by excision of flowers and chilling of roots with those where sink activity was not modified. Reduction in sink activity led to a reduction in the maximum rate of photosynthesis, to retention of fixed carbon in source leaves and to the progressive accumulation of raffinose-family oligosaccharides. This ultimately affected the extractable activities of invertase and sucrose phosphate synthase. At the end of the light period, invertase activity was significantly higher in treated plants. By contrast sucrose phosphate synthase activity was significantly lower in treated plants. We propose that reducing sink activity in L. album is associated with a shift in metabolism away from starch and sucrose synthesis and towards sucrose catabolism, galactinol utilisation and the synthesis of raffinose-family oligosaccharides.

Chromium mass balance in sodium chlorate process

Kuudenarvoista kromia käytetään natriumkloraatin valmistuksessa prosessin tuotantotehokkuuden ja turvallisuuden parantamiseksi. Kromia kuitenkin poistuu prosessista muutamaa reittiä pitkin. Koska kuuudenarvoisella kromilla on syöpää aiheuttavia, mutageenisiä sekä lisääntymiselle myrkyllisiä ominaisuuksia, olisi tärkeää ymmärtää, miten kromi kulkeutuu prosessin eri osiin, ja kuinka paljon sitä poistuu prosessista. Tämä on tärkeää, jotta osataan hallita kromin käytöstä aiheutuvat riskit, sekä toisaalta myös tehostaa kromin käyttöä prosessissa. Työn tarkoituksena oli tuottaa tietoa kromin käytöstä natriumkloraattiprosessissa. Työssä tutkittiin kromitasetta prosessin keskeisimmissä yksikköoperaatioissa. Myös kromin saostumista katodien pinnalle arvioitiin määrällisesti. Eri prosessinäytteistä tutkittiin lisäksi kromin hapetusasteita. Edellä mainittuja tutkimuskohteita varten määritettiin prosessinäytteiden kromipitoisuus. Eri prosessioperaatioille suoritettiin lisäksi taselaskelmat. Työn tuloksena esitettiin kromitase sekä yksikköoperaatioille että koko prosessille. Erinäisten epätarkkuustekijöiden vuoksi tasetta ei kuitenkaan pystytty määrittämään halutulla tarkkuudella, ja siksi työssä esitettyä tasetta voidaan pitää vain suuntaa antavana laskelmana. Katodien pinnalle saostunutta kromin määrää pidettiin kuitenkin oikean suuruusluokan tuloksena. Prosessinäytteiden hapetusasteita ei voitu arvioida, sillä saadut kokonaiskromitulokset eivät olleet täysin luotettavia. Huolimatta tulosten epätarkkuudesta, työ tuotti tärkeää tietoa prosessin toiminnasta kromin suhteen. Työtä voidaan hyödyntää jatkossa monin tavoin prosessin kromitaseen seurannassa.

Consumer online communication of corporate social responsibility in the sin industry context: Cases in the global online gambling industry.

So-called sin industries are often related to harmfulness, unethical business, and unproductiveness. Nowadays, the alcohol, gambling, and tobacco industries are most often considered to be part of sin industries, which is also the context of this study. However, the definition of a sin industry is always related to time and culture. Despite the controversies of sin industries, there are studies that have shown that corporate social responsibility (CSR) engagement is even more important for sin industries than for normal industries and that CSR has a positive effect on firm value in sin industries. With CSR this study refers to an ideology where company takes mostly voluntary actions towards various groups of stakeholders and the environment. In other words, the company goes beyond the legal norms and regulations. In particular, the purpose of this thesis is to find out how companies, operating in the online gambling industry, communicate about their CSR actions to consumers at their web pages. The online environment is essential for this study as online gambling environment is a source of many controversies in comparison to the traditional gambling halls and casinos. These include, for example, greater accessibility, anonymity, and availability of the service. This study uses qualitative textual analysis as its approach, more precisely the discourse analysis. In addition, as this study focuses on large international companies and their actions, also case study approach will be presented. The cases studied are Mybet, Unibet, and Bwin.Party. In order to study the subject, elements from discourse analysis are combined with insights of essential CSR theories, and the specific characteristics of the online gambling industry. As a background for the framework, this study uses the framework of Du & Vieira (2012). After analyzing the discourses of CSR communication and CSR practices, it seems that all of the case companies still do not use all the potential that the online environment provides in terms of CSR or stakeholder communication. There are large differences between different communication tools used at different web pages (gambling pages vs. corporation pages) and between the firms’ CSR profiles. Moreover, there are large differences in the CSR practices used in the web pages of the case companies. The findings of this study are partially alarming as the case companies represent the largest companies in the industry. There are major varieties between the companies’ CSR communication and clear shortcomings in some parts of the online communication. Moreover, the trust of the consumer was broken in some places. If this is the standard that the biggest players in the industry have set with regards to CSR communication, it is probable that the smaller players are performing even worse. Moreover, the regulators are most likely concentrating on the larger companies, so the smaller companies might have fewer incentives and pressure to perform according to the regulations or exceeding the legislation. The conclusions of this thesis provide insights to managers, regulators, and scholars. Suggestions for future studies are provided as well.

Erythrocytes may contain a ouabain-insensitive K+-ATPase which plays a role in internal K+ balance

Erythrocytes are useful in evaluating K+ transport pathways involved in internal K+ balance. Several forms of H+,K+-ATPase have been described in nephron segments active in K+ transport. Furthermore, the activity of a ouabain-insensitive isoform of H+,K+-ATPase expressed in collecting duct cells may be modulated by acid-base status. Various assays were performed to determine if a ouabain-insensitive K+-ATPase is present in rat erythrocytes and, if so, whether it plays a role in internal K+ balance. Kinetic studies demonstrated that maximal stimulation of enzyme activity was achieved with 2.5 mM K+ at pH 7.4. Subsequent experiments were performed on erythrocyte membranes collected from animals submitted to varying degrees of K+ homeostasis: control rats, K+-depleted rats, K+-loaded rats, and rats rendered hyperkalemic due to acute renal failure. As observed in the collecting duct cell studies, there was a significant decrease in the activity of ouabain-insensitive K+-ATPase in the erythrocytes of both K+-loaded and metabolically alkalotic K+-depleted rats. However, this enzyme activity in erythrocyte membranes of rats with metabolic acidosis-related hyperkalemia was similar to that of control animals. This finding may be interpreted as resulting from two potentially modulating factors: the stimulating effect that metabolic acidosis has on K+-ATPase and the counteracting effect that hyperkalemia and uremia have on metabolic acidosis. In summary, we present evidence of a ouabain-insensitive K+-ATPase in erythrocytes, whose activity is modulated by acid-base status and K+ levels.

Brazilian version of the Berg balance scale

The purpose of the present study was to translate and adapt the Berg balance scale, an instrument for functional balance assessment, to Brazilian-Portuguese and to determine the reliability of scores obtained with the Brazilian adaptation. Two persons proficient in English independently translated the original scale into Brazilian-Portuguese and a consensus version was generated. Two translators performed a back translation. Discrepancies were discussed and solved by a panel. Forty patients older than 65 years and 40 therapists were included in the cultural adaptation phase. If more than 15% of therapists or patients reported difficulty in understanding an item, that item was reformulated and reapplied. The final Brazilian version was then tested on 36 elderly patients (over age 65). The average age was 72 years. Reliability of the measure was assessed twice by one physical therapist (1-week interval between assessments) and once by one independent physical therapist. Descriptive analysis was used to characterize the patients. The intraclass correlation coefficient (ICC) and Pearson's correlation coefficient were computed to assess intra- and interobserver reliability. Six questions were modified during the translation stage and cultural adaptation phase. The ICC for intra- and interobserver reliability was 0.99 (P < 0.001) and 0.98 (P < 0.001), respectively. The Pearson correlation coefficient for intra- and interobserver reliability was 0.98 (P < 0.001) and 0.97 (P < 0.001), respectively. We conclude that the Brazilian version of the Berg balance scale is a reliable instrument to be used in balance assessment of elderly Brazilian patients.

Balance between education- and research-oriented publications from a Brazilian University Hospital

We analyzed the trends of scientific output of the University Hospital, Federal University of Rio de Janeiro. A total of 1420 publications were classified according to pattern and visibility. Most were non-research publications with domestic visibility. With time, there was a tendency to shift from non-research (or education-oriented) publications with domestic visibility to research publications with international visibility. This change may reflect new academic attitudes within the institution concerning the objectives of the hospital and the establishment of scientific research activities. The emphasis of this University Hospital had been on the training of new physicians. However, more recently, the production of new knowledge has been incorporated as a new objective. The analysis of the scientific production of the most productive sectors of the hospital also showed that most are developing non-research studies devoted to the local public while a few of the sectors are carrying out research studies published in journals with international status. The dilemma of quality versus quantity and of education versus research-oriented publication seems, however, to continue to exist within the specialized sectors. The methodology described here to analyze the scientific production of a university hospital can be used as a tool to better understand the evolution of medical research in Brazil and also to help formulate public policies and new strategies to include research among the major objectives of University Hospitals.

Integrating corporate social responsibility into business in Finnish consumer goods companies

The motives for this study originated from the notion that surprisingly little academic literature is found on actually managing and putting corporate social responsibility (CSR) into practice, in comparison with the definitions and frameworks of the concept itself. Regardless of the author, CSR has been considered consisting of three dimensions: economic, social and environmental. The question behind the three dimensions has always been whether socially and environmentally responsible behavior can lead to increased economic performance and improve the competitiveness of a company. Most of the current CSR development has related to the quantification of environmental and social performance in order to review these along with the established financial key ratios, which are based on the law and the reporting obligation of the companies. However, the previous research has mainly focused on US companies whereas studies with a European viewpoint, let alone Nordic, have been mostly lacking. Furthermore, it has been discovered recently that the integration of corporate responsibility into business is identified as the greatest challenge in CSR management in Finnish large companies. Therefore the integration of CSR into business in Finnish consumer goods companies provided an interesting, topical and somewhat obscure purpose for this study. This was further divided into three research questions concerning the reasons for CSR engagement, the role of the stakeholders and the practice of corporate responsibility. This study did not aim to build a new theory; instead an explorative viewpoint was regarded more appropriate. Accordingly, qualitative research approach and case study design were adopted in the study. Semi-structured theme interviews were used as a primary data collection method and complemented with secondary data such as websites, responsibility reports and another recent CSR study. There were four Finnish managers as interviewees of whom three presented companies and one non-profit organization. The results were somewhat convergent but differences arose as a result of the companies being at different stages as regards corporate responsibility. However, this provided only more insight into the implementation of CSR. The voluntary CSR initiatives, responsibility reporting, stakeholders and CSR management were identified as the most important viewpoints on the practical side of CSR, besides a key requirement for the integration of CSR into business to be credible was found to be a favorable management attitude. Based on the findings of this study it was admitted that giving concrete advice on CSR management is really a challenge and there is no one generally accepted and right manner to integrate corporate responsibility successfully into business.
