Abstract

Designing and adapting organizations to secure viability and increase performance is a challenge. Research models often fail to integrate corporate social responsibility (CSR) aspects in the concept development and its implementation. Therefore, the aim of this study is to propose a holistic approach how organizations can be designed, changed and managed considering its implications to service management under a CSR approach. Hereby the Viable System Model was applied. Its structure can be applied to any kind of structured organization and for its management with goals to be achieved in modern society; however focus of the research is the cluster of charity organizations. Goal of the developed model is to be able to react to all potential organizational environments by taking decisions correctly and in the right moment based on the needed information reducing service lead times and manpower allocation as well as increasing the service level. To ensure this, service management tasks were assigned and standardized communication channels were defined. In conclusion this proposed approach empowers organizations to have internal mechanisms to secure viability by pursuing the goal of a high performance CSR approach.

Abstract

Designing, changing and adapting organizations to secure viability is challenging for companies. Researchers often fail to holistically design or transform organizations. Thus, the aim of this study is to propose a holistic approach how organizations can be designed, changed or managed considering also its implications to production management following lean management principles. Hereby the Viable System Model was applied. This structure can be applied to any kind of structured organization and for its management with goals to be achieved in modern society; however focus of the research is the cluster of manufacturing and assembly companies. Goal of the developed organizational model is to be able to react to all potential company environments by taking decisions regarding organization and production management functions correctly and in the right moment based on the needed information. To ensure this, standardized communication channels were defined. In conclusion this proposed approach enables companies to have internal mechanisms to secure viability and also in production to reduce necessary stocks, lead times, manpower allocation and leads to an increase of the service level to the final customer.

Abstract

This study aimed to describe the acute impact of extended interval training (EIT) on physiological and thermoregulatory levels, as well as to determine the influence of athletic performance and age effect on the aforementioned response in endurance runners. Thirty-one experienced recreational male endurance runners voluntarily participated in this study. Subjects performed EIT on an outdoor running track, which consisted of 12 runs of 400 m. The rate of perceived exertion, physiological response through the peak and recovery heart rate, blood lactate, and thermoregulatory response through tympanic temperature, were controlled. A repeated measures analysis revealed significant differences throughout EIT in examined variables. Cluster analysis grouped according to the average performance in 400 m runs led to distinguish between athletes with a higher and lower sports level. Cluster analysis was also performed according to age, obtaining an older group and a younger group. The one-way analysis of variance between groups revealed no significant differences (p≥0.05) in the response to EIT. The results provide a detailed description of physiological and thermoregulatory responses to EIT in experienced endurance runners. This allows a better understanding of the impact of a common training stimulus on the physiological level inducing greater accuracy in the training prescription. Moreover, despite the differences in athletic performance or age, the acute physiological and thermoregulatory responses in endurance runners were similar, as long as EIT was performed at similar relative intensity.

Abstract

In handball, throwing velocity is considered to be one of the essential factors in achieving the ultimate aim of scoring a goal. The objective of the present study was to analyze the effect of a core training program on throwing velocity in 30 handball players (age 18.7 ± 3.4 years, body height 179.3 ± 7.0 cm, body mass 78.9 ± 7.7 kg), 16 of whom were in the junior category and 14 of whom were in the senior category. The 30 players were randomly divided into two groups, the control group (n = 15) and the experimental group (n = 15). For a period of ten weeks, both groups attended their regular handball training sessions (four per week), but in addition, the experimental group participated in a program specifically aimed at progressively strengthening the lumbo-pelvic region and consisting of seven exercises performed after the general warm-up in each regular session. Pre- and post-tests were carried out to analyze each player’s throwing velocity from different throwing positions and thus assess the effects of this specific training program. Statistically significant differences (p ≤ 0.05) in throwing velocity were observed between the experimental group, which presented a percentage improvement of 4.5%, and the control group, which did not show any improvement. The results seem to indicate that an increase in the strength and stability of the lumbo-pelvic region can contribute to an improvement in the kinetic chain of the specific movement of throwing in handball, thus, increasing throwing velocity.

Abstract

Sustainable development has been highlighted widely in productive sectors such as the sugar industry with new paradigms and trends such restructuring of sugar mills in biorefineries and development of green chemical from byproducts, considering issues such as technology adoption towards sustainability, circular economy, climate change, value chain, sustainability assessment and decision making. Production of cane sugar is one of Mexico’s main agro-industries; it conveys numerous positive socio-economic impacts and presents opportunities for productive diversification and enhanced profitability and competiveness. The sugar industry faces sustainability challenges due to the management of natural resources like soil, water, fossil fuels and agrochemicals, as well as the impacts of its greenhouse gas emissions and socio-economic constraints. However, sustainability of cane and sugar production cannot be assessed due to a lack of methodological frameworks for integrating economic and environmental indicators. We propose an index for Mexico’s sugar agro-industry that facilitates the identification of those system components that impact sustainability. This index is based on a reduced number of indicators aggregated through a multi-criteria evaluation using the analytical hierarchy process (AHP). We apply this index to evaluate four sugar production systems in Mexico: producers of raw, refined, muscovado sugar and ethanol. Results show that systems with a high agro-industrial yield present better sustainability performance. This study is relevant because it provides quantitative information for decision makers towards a sustainable sugarcane agro-industry, based on the indicators used to build the sustainability index, to address actions as increase productive diversification by-products based, improve access to credit, irrigation, management practices and raw material quality reducing production costs, eliminate fossil fuel use in factories, make fertilizer application more efficient and reduce the area that is burned for manual harvest.

Abstract

With the proliferation of mobile and distributed systems capable of providing its geoposition and even the geoposition of any other element, commonly called point of interest, developers have created a multitude of new software applications. For this purpose, different technologies such as the GPS or mobile networks are used. There are different languages or formats used to define these points of interest and some applications that facilitate such work. However, there is no globally accepted standard language, which complicates the intercommunication, portability and re-usability of the definitions of points of interest currently in use. In this paper, we take the first steps towards a language and a development environment independent of the underlying technologies, allowing developers to define the points of interest in a simple and fast way, and automatically generate other different formats from the same definition that can be considered a bridge among current technologies. We use the Model-Driven Engineering approach, focusing on the creation of models to abstract the definition of systems from the underlying technologies.

Abstract

Background and aims: Bromocriptine is a dopaminergic (D2) agonist that has shown hypoglycemic and normotensive activity in preclinical and clinical studies. The main objective of this study was to investigate the effect of bromocriptine plus metformin on glycaemia and blood pressure in patients with type 2 diabetes mellitus (T2DM).

Material and methods: An open-label randomised controlled trial was conducted for three months. It involved two groups (n=10), each containing 2 women and 8 men with an average age of 50 years. One group was given monotherapy (MT) with metformin (850 mg every 12 h) and the other combined therapy (CT) with the same dose of metformin plus an increasing dose of bromocriptine (from 1.25 mg per day to 2.5 mg per day). The parameters monitored were glycaemia, glycated hemoglobin (HbA1c), serum creatinine, blood pressure, and the body mass index.

Results: CT was able to significantly decrease the level of glycaemia, HbA1c and diastolic blood pressure, whereas MT had no effect on any of the measured variables.

Conclusions: The ability of CT with bromocriptine and metformin to control glycaemia and produce a normotensive effect reaffirms its advantages for controlling T2DM. Further research is needed to improve this therapeutic strategy.
