Digitalization is a transformation process which has already affected many parts of industry and society and is expected to yet increase its transformative speed and impact. In the energy sector, many digital applications have already been implemented. However, a more drastic change is expected during the next decades. Good understanding of which digital applications are possible and what are the associated benefits as well as risks from the different perspectives of the impacted stakeholders is of high importance. On the one hand, it is the basis for a broad societal and political discussion about general targets and guidelines of digitalization. On the other hand, it is an important piece of information for companies in order to develop and sustainably implement digital applications. This article provides a structured overview of potential digital applications in the German energy (electricity) sector, including the associated benefits and the impacted stakeholders on the basis of a literature review. Furthermore, as an outlook, a methodology to holistically analyze digital applications is suggested. The intended purpose of the suggested methodology is to provide a complexity-reduced fact base as input for societal and political discussions and for the development of new digital products, services, or business models. While the methodology is outlined in this article, in a follow-up article the application of the methodology will be presented and the use of the approach reflected.

AbstractDesign research as a field has been studied from diverse perspectives starting from product inception to their disposal. The product of these studies includes knowledge, tools, methods, processes, frameworks, approaches, and theories. The contexts of these studies are innumerable. The unit of these studies varies from individuals to organizations, using a variety of theoretical tools and methods that have fragmented the field, making it difficult to understand the map of this corpus of knowledge across this diversity.In this paper, we propose a model-based approach that on the one hand, does not delve into the details of the design object itself, but on the other hand, unifies the description of design problem at another abstraction level. The use of this abstract framework allows for describing and comparing underlying models of published design studies using the same language to place them in the right context in which design takes place and to enable to inter-relate them, to understand the wholes and the parts of design studies.Patterns of successful studies could be generated and used by researchers to improve the design of new studies, understand the outcome of existing studies, and plan follow-up studies.

Always before we start creating or accessing a particular system, it is more than necessary to have a clearer picture of how to create, respectively, how to approach a certain system, in this case of a e-business system. It is much easier as for systems makers, as well as for ordinary users when they have before them a model of how to be accessed in such a system, because such a thing will orient users much easier to purchase products online through various systems on the one hand, but on the other hand it would help makers of systems create much easier such systems when they have already before them the right design. Modeling systems may be done in different ways, depending on the context of its research, but we in this paper we will use UML diagrams for modeling online system where we will make a comparison between UML diagrams and we will present each type of UML diagram in terms of customer access in online systems. Also using predictive techniques as CPM and PERT techniques in the paper we will present the main activities required for access to an online system by different users, and their graphic presentation and critical path finding, which shows the best way to approach such a system. There shall not fail and the description of business models and the introduction of some e-business models that are commonly used in practice in the days of today.

The Relationship

Nowadays, and more than never, businesses´ stakeholders are demanding Social Responsibility (SR) and innovation. In this situation, any business is concerned about how to implement social and innovative practices in creating economic and social value at the same time. This chapter analyzes the relationship between SR and innovation in cooperatives. On the one hand, even acknowledging that the degree of implementation of SR is still different in companies, cooperatives seem to be responsible by nature. However, on the other hand, traditionally innovation has been not a visible strength in the cooperative enterprises. The focus is centered on a specific place: the olive oil cooperatives in the south of Spain and we will describe the cooperative entrepreneurial ecosystem created around this territory, demonstrating how SR and innovation are important features related to competitiveness and success. Cooperatives are strategic business models able to foster development in traditional rural areas, so we can define them as an entrepreneurial ecosystem in smart territories.

In this article the author points some actual questions of the transformation process in the Croatian society. The analysis of Z. Brzezinski is used as analytical model which basic function is of strategic meaning. The idea was to show how Croatia is close or distant from the mainstream of transformation process. The conclusion is that the successful achievements of the transformation depends both on the influence of the International community, political and economic on the one side and on the nature of the postcomunist self-determination of Croatian society, on the other side.98

This article reports on the insights gained from multilingual nursing lecturers and students at Mzuzu University in Malawi on the languages they use and prefer in a classroom setting. Research (Setati, Chitera and Essien, 2009; Chowdhury 2012) has found that both lecturers and students in multilingual and multicultural settings favour code-switching practices in the classroom setting. Code-switching is, therefore, an important phenomenon, which researchers should continue exploring because of the several distinctive attributes associated with it. The study adheres to qualitative and quantitative designs through the use of a questionnaire and follow-up interviews as methods of data collection. The results reveal that both lecturers and students favour code-switching from English to Chichewa during lectures. From both lecturers’ and students’ perspectives, code-switching helps to translate and clarify difficult concepts. It also helps to prepare students for the nursing profession. The study has some practical and pedagogical implications. On the one hand, it contributes some meaningful insights for language planners and policy-makers; on the other hand, the study sheds important light on the need to include the workplace dimension during language in education and language planning conversations. This study is also important because it addresses the issue of how code-switching might effectively be exploited as a communicative and pedagogical resource in instruction.

The Batwa – A Hundred Years of Transformation. Between Globalisation, State and Tourism The article is a deep refl ection on changes taking place in minority cultures, not only in contact with their larger neighbours, but also, and above all, under the infl uence of globalisation processes and the rapid development of tourism. The research is structured in order to present the Batwa people living in the African Great Lakes region from a broader time perspective. The juxtaposition of two research periods, one from the early 20th century (Jan Czekanowski) and the other from the 21st century (Lucjan Buchalik), made it possible to track the changes in the everyday life of this community. On the one hand, the Batwa are marginalised, and on the other hand, they are being absorbed by the surrounding, more dominant peoples. Studying the transformation process, one can notice that the Batwa accepted many changes resulting from their contacts with the outside world. It was the process of forcible displacement from their historical territories that threatened the existence of this community.

AbstractThe paper reviews the last IMIA-WG6 recommendations, issued along two themes: (1) how to better share common results and (2) how to conduct new research and development efforts. Some of the major discrepancies in the field are reviewed. The paper intends to offer insight into two areas, first, in the issue of knowledge representation and, second, in the science of meaning, incorporating the broad intersection of computational linguistics, semantics, conceptual approach, and denotation. The Ogden-Richards meaning triangle is used as a convenient organizing principle to maximize the scope of understanding among the different schools, particularly in areas of linguistics and semantics on the one side and denotation and conceptual approach on the other. In conclusion, there is a need for clarification and for more scientific pragmatism.

This paper presents the link between self-control and childhood enuresis, assuming that enuresis is maintained by deficiencies in self-control skills, whether caused by physiological, behavioral, or cognitive components. Acquisition of self-control skills is proposed as helping in eliminating enuresis. Seventy-seven enuretic children (aged 7 to 14) were randomly assigned to three treatment modes (bell and pad, token economy, and cognitive therapy) and to one control group. The self-control skills of children and their parents and the frequency of enuresis were measured before and after treatment. Results showed a negative correlation between self-control and enuresis on the one hand and between the acquisition of self-control skills and recovery from enuresis on the other hand. The results also highlighted the need for a follow-up period to determine the different longer-term effects of treatments.

OBJECTIVE: to evaluate discharge in a group of patients with cutaneous melanoma according to recently established criteria. METHODS: we conducted an observational, cross-sectional study with 32 patients at the Hospital Universitário Clementino Fraga Filho (HUCFF) / Universidade Federal do Rio de Janeiro (UFRJ), between 1995 and 2013, in the following stages: IA (17 cases, 53.12%), IB (4 cases, 12.5%), IIA (3 cases, 9.37%), IIC (1 case, 3.12%), IIIB (1 case, 3.12%), IIIC (3 cases, 9.37%), melanomas in situ (2 cases, 6.25%), Tx (1 case, 3.12%). RESULTS: the follow-up time varied from one to 20 years (stage IA), five to 15 years (stage IB), six to 17 years (stage IIA), 20 years (stage IIC), 23 years (stage IIIB) and 14 to 18 years (stage IIIC). One melanoma in situ (subungueal) was discharged in the fourth year of follow-up and the other was promptly discharged. The Tx melanoma was followed for 12 years. We observed no relapses or recurrences in the period. CONCLUSION: although a controversial issue, it was possible to endorse the discharge of the patients since our follow-up time had already exceeded the one recommended by the other authors.

The last two compounds in a 5-membered series of aromatic dinitro compounds are reduced in a completely different manner at mercury electrodes. 2,2'-Dinitrodiphenylmethane (I) - in which a conjugation of both symmetrical moieties is ruled out - is electrolytically reduced in an eight-electron step to a bishydroxylamine this being most stable between pH 4.5 and 5.0. In processing the catholyte increase in concentration of this product leads to its intermolecular disproportionation, resulting in the formation of dibenzo[b, e]-1,2-diazepine 5-oxide (IV) and 2,2'-diaminodiphenylmethane (III). 2,2'-Dinitrobenzophenone (II) reduces at more positive potentials. Its preparative electrolysis in acetonitrile (with 0.1M-N(n-C4H9)4PF6 as supporting electrolyte) the application of which was made necessary by the low solubility of II in ethanol, proceeding in an anomalous way. In the most positive cathodic wave a radical anion results, the following cathodic wave corresponds to a 6-electron reduction of the one nitro group to an amino group while the other nitro group splits off as the anion NO-2 (this later giving an anodic wave). Its formation has been proved by standard addition in polarography and by a qualitative analytical test. The product which results through this electrode process and a follow-up chemical reaction is acridone. This in turn, reduces in the third, most negative 4-electron wave to dihydroacridine. The comparison of all substances studied in this series reveals that their reducibility decreases with respect to the link X, viz. in the sequence CO > O > S and CH2 > NH. The electrolytical reduction on mercury cathodes occurs in a similar manner with analogues where X = O, S or CH2. Here, the main intermediate is the bis-hydroxylamine the stability of which predetermines the structure of final products. The other group comprises the substances with X = CO and NH. Here the main intermediate is the 2-nitro-2'-amino-diphenyl-X which is formed in a 6-electron process taking place at one of the nitro groups. The follow-up cyclization reaction leading to seven-membered heterocyclic rings located between two benzene nuclei only occurs with analogues of the type X = CH2, O and S. A partial reduction of dinitro compounds of this series has been observed with the analogue containing the NH link although that with X = CO has generally good preconditions for this mechanism.
