Abstract
Faltung equations (closed cycle type) have a wide range of biological applications, nonetheless, they are poorly studied. We use a Volterra‐Kostitzin model (which is a Faltung equation) to study the dynamics of a certain species, where the integral term represents a residual action. The complexity of resolution of this non‐linear equation using classical numeric methods is here solved with the Adomian decomposition method. Our method provides the same graphic solution as others do, such as the numeric method Miladie. However, the decomposition method of Adomian has the advantage that neither time nor space are considered discontinuous and that it gives an analytical solution with a reliable approximation.

Abstract
In a globalised economy, the EU, being self-confident, could shape international standards by defending and promoting its own socioeconomic model. Social democratic parties rhetorically confess the need for a ‘European social model’, but meanings and ways to achieve it differ largely. In a comparative case study on the programmatic positioning of the German Sozialdemokratische Partei Deutschlands and the Spanish Partido Socialista Obrero Español, the parties' perspectives on the integration mode and their handling of the Economic and Monetary Union framework and its crisis over the last decade are traced. Although similar paths from neoliberal convictions of the ‘third way’ to a positive integration process in a fiscal union setting are found, the scope and levels vary, illustrating the abilities of both parties to meet new transnational challenges. The crisis of the Eurozone was a definitive turning point for the positioning of the Social Democrats in Spain in favour of more political and fiscal integration. In contrast, their German comrades already advocated increased social integration of the EU since 2005 but remained very cautious regarding reforms of the economic framework established by the Eurozone.

Abstract
Students need to learn and practice creative thinking skills to ensure success in solving everyday, national, and global problems that include those affecting economic issues. The global economy requires workers to have research and innovation skills that depend upon creativity. However, many current educational programs focus mostly on factual content, doing little to inspire or apply the creative process. The project presented here shows an engaging activity that combines creative thinking skills with economic content. Although the activity occurred in a college course on creativity theory and practice, this challenging game can be easily adapted and embedded in the Kindergarten-12 social studies curriculum. This article discusses the set-up of the activity and its connection to creativity theory and curriculum standards. It showcases the work of eleven participants who each made a unique object or scene from a given set of craft and recycled materials, subsequently relating the resulting product to a current economic issue. Photographs of the resulting products are provided along with descriptions of the theme of each item, its connection to economics, and creative aspects of the work. Suggestions for adaptation to the Kindergarten-12 classroom are given.

Abstract
Purpose
The purpose of this paper is to compare the recent social welfare performance of old and new members of the European Union, and to establish whether a specific East‐European social model (ESM) is emerging.
Design/methodology/approach
The concept of social model is explored in the context of the historical development of economic and social policy integration in the European Union, with emphasis on reform measures and the EU enlargement process post‐1990. Guided by Sapir's typology of ESMs, the performance of 15 West‐European countries is analysed and compared with that of ten East‐European countries, relative to key economic and social indicators. The results are then used to determine whether a typology of East‐ESMs could be produced.
Findings
Social welfare performance in the new EU members indicates two different patterns and levels of development, which at this stage separate East‐European countries into two distinct groups. While two divergent trends may be emerging, it is perhaps too soon to conclude that any specific East‐ESM is taking shape. Results so far suggest that, in Eastern Europe, the influence of a welfarist social model appears more beneficial than that of market liberalism.
Research limitations/implications
This paper is limited to the comparative analysis of social welfare performance in six country groups. To obtain a full picture of the current development of social models in the European Union, it should be complemented by a separate examination of deliberate efforts by national governments towards in integrating economic and social policies in normative social models. The analysis itself could be expanded to include other significant social indicators, such as the level of employment protection or the Human Development Index.
Practical implications
While deliberate policy efforts are not always necessary for a social model to emerge, public awareness of cultural and regional trends in social welfare performance, analysed through the filter of social model typology, can significantly inform future social and cultural practices, as well as national government policies, directed towards improving national welfare.
Social implications
This analysis can provide a theoretical basis for the integration of national economic and social policies in a coherent philosophy of multi‐dimensional development in Eastern Europe.
Originality/value
The paper selects historically relevant indicators of economic and social performance, undertakes a comparative analysis of six European country groups, draws conclusions on the current state of social welfare in East‐European countries relative to their Western counterparts and makes recommendations regarding the development of social model conceptions in Eastern Europe.

Abstract
In January 2011, during the World Economic Forum's annual meeting in Davos, Switzerland, Jason Sterling, a hedge fund manager, was conducting online research to see if he could trade on any newsworthy information emerging from the summit. Sterling's fund traded primarily in sovereign debt, and he needed to figure out if European leaders would be able to come up with a viable solution to the crisis or whether the debt crisis would lead to the default of several European nations. He knew that if a solution was not found in the coming weeks, the sovereign debt markets could be thrown into turmoil.

Abstract
Purpose
The purpose of this paper is to attempt to outline the standard profile of the typical wine consumer, by identifying some relevant features that can influence his/her purchasing choices. Therefore, the purpose of the research is to identify the pre-eminent attributes for wine consumers and the different levels of importance that consumers ascribe to the attributes identified at the time of purchase.
Design/methodology/approach
In order to collect the necessary data, an ad hoc questionnaire was utilized. The questionnaire, which was anonymous, was directly distributed with the face-to-face method. In total, 1,500 copies of the questionnaire had been prepared. The data collected were processed through the use of the binary logistic regression model and the ordinal logistic regression model. The first binary logistic regression model allows to evaluate the dependence of the dichotomous variable on some potential predictors. The ordinal logistic regression model, known in literature as a cumulative model of proportional quotas, is generally appropriate for situations in which the ordinal response variable has discrete categories.
Findings
The results returned by the elaboration of the binary logistic regression model refer to the influence of the variables sex, age, educational status and income on the “wine consumption” result, which is a dichotomous variable. The only variables found to be statistically significant are gender and educational status. The most significant variables that emerged from the implementation of the ordinary logistic regression model are gender, brand, choice based on price, place of production, harvest and certification. The analysis carried out has shown that with reference to wine as a product, it is essential to focus on several attributes, among which there are of course quality and brand.
Research limitations/implications
Although field experiments are extremely useful for testing behavioral hypotheses, they are often limited by a small sample. Future research in this area might focus on the knowledge level of sustainable wine of the consumer. In relation to the knowledge of the characteristics of the wine, it is possible to estimate the willingness to pay a surplus for a wine produced with sustainable methods by the consumer and the possible level of price premium.
Originality/value
The originality of the research lies mainly in a deeper knowledge of wine consumption trends. This information is useful to better define the wine market and to allow, especially to small businesses, to establish effective marketing strategies in relation to the real preferences of consumers and the decision-making process of choice put in place by them. In order to achieve this, the influence of all the variables on the “satisfaction of wine consumption” result was evaluated. The strength of this paper is the use of an adequate statistical approach based on the use of models, typical of inferential statistics, to reach conclusions that can be extended to the entire population of wine growers.

Abstract
Purpose
The purpose of this paper is to investigate the discretionary use of loan loss provisions in the Chinese banking sector during the global financial crisis. The objective of this paper is twofold: to add new evidence to the scant literature dealing with a peculiar banking sector, such as the Chinese one, and to shed more light on banks’ provisioning behaviour during stressed financial markets conditions.
Design/methodology/approach
Using bank-level balance sheet and financial statements data, the authors test for income smoothing and capital management hypotheses, and detect differences in provisioning decisions of listed banks and unlisted financial intermediaries during turbulent financial markets conditions.
Findings
The authors find support for the income smoothing hypothesis, but not for the capital management one. Chinese listed banks appear to be less risky and less involved in income smoothing to shift their risk, when compared to unlisted credit institutions.
Social implications
The results obtained from this paper help to understand the functioning of bank provisioning regime in the Chinese banking system and how provisioning mechanisms can address the issues associated with the pro-cyclicality of bank capital requirements.
Originality/value
Though referred to a particular banking sector, such as the Chinese one, the results of this paper can provide a tremendous incentive to those national and international authorities that are bound to promote forward-looking provisioning practices. These practices would allow banks to build a buffer of reserves to face the downward pressure on earnings and capital associated with periods of worsening credit quality.

Abstract
Purpose
In the Europe of the nineteenth century, a significant increase in abandoned children was caused by demographic pressures and growing economic difficulties that progressively afflicted the lowest social strata of the population. Those who had neither family, nor school, educated themselves in the streets or learned from patron‐tutors who aspired to produce a specific social subject, channelizing their “congenitally” subversive tendencies through a certain kind of structured apprenticeship. This model of education (or “bad education”) can be defined as the formalization, paradoxically devoid of symbols and alphabet, of the experience of the street within a specific system of knowledge. The purpose of this paper is to seek to encounter in literary sources the traces of the education of these marginalized children.
Design/methodology/approach
The authors intend to study, by means of the testimony of novels, the mentality of this historic period and the phenomenon of this very different kind of childhood. The epistemological and methodological viewpoint that is adopted is both ethnographic and historical, since the authors are attempting to understand and establish the evolving nexuses and dynamics of the educational phenomenon that is the object of the investigation.
Findings
The central objective of this investigation lies in the notion of “bad education”. By “bad education” the authors mean the presence of an educational itinerary, an acculturation, a personality formation, and a professionalization that have all strayed from the dominant, hegemonic social models. This “model” of education forms part of the prevailing educational philosophy of a particular epoch and historical situation, as demonstrated throughout this paper.
Originality/value
This paper proposes an operation of educational archaeology. However, this operation can contribute to an epistemological awareness that can greatly benefit both the pedagogical reflections of our time and the educations of so many marginalized children who inhabit the destitute streets of the contemporary metropolis.

Abstract
Purpose
This paper aims to examine women leaders from diverse career backgrounds and ethnicities to discover their perspectives of their leadership roles and empowerment to determine similarities and differences among them, focusing on the perspectives of African American women.
Design/methodology/approach
The review process began with a comprehensive review of African American women in history in the context of leadership and empowerment. Next, a Q-sort methodology was used as a semi-qualitative approach for women leaders to rank words of empowerment and facilitate discussions among these women. The Q methodology is known for exploring issues that are correlated with individuals who are influenced with personal feelings and opinions.
Findings
The paper concludes that perceptions of leadership roles differ among the African American women leaders when compared to other ethnicities. The results support the idea that women from diverse ethnic backgrounds have different experiences in the workplace, and these experiences influence how they identify factors they perceive as beneficial to them in terms of their perspectives on leadership and empowerment. Several themes emerged for African American women leaders including being overlooked, marginalized, undervalued and unappreciated in their professions as leaders due to their dual minority status. As it is now as it was in the past, such barriers can deter or stop progression for African American women leaders.
Originality/value
The history of African American women in leadership roles is scantily recognized or not recognized at all. This paper highlights leadership roles and barriers for African American women currently in leadership roles in contrast to other women. The issues they face are still similar to those faced by African American women in earlier decades in spite of increased career mobility. A relatively understudied topic in leadership and management history in general, this paper provides a unique lens from which to build awareness about the leadership roles and empowerment of African American women and to effect needed change.
