Abstract

Calorimetric measurements have been performed in glassy Se90M10 (M=In, Te, Sb) alloys to study the effect of In, Te and Sb additives on the kinetics of glass transition and crystallization in glassy Se90M10 system. Kinetic parameters of glass transition and crystallization such as the activation energy of glass transition (E g), the activation energy of crystallization (M c), the order parameter (n), the rate constant (K), etc. have been determined using different non-isothermal methods. The composition dependence of the activation energies of glass transition and crystallization processes is also discussed.

Abstract  

Specific heat measurements have been made in a-Se and a-Se90M10 (M = In, Sb, Te) alloys using differential scanning calorimetry (DSC) technique to see the effect of additives In, Sb and Te on the specific heat in a-Se. An extremely large increase in the specific heat values has been observed at the glass transition temperature. It has also been found that the values of C p below glass transition temperature (C pg) and after glass transition (C pe) are highly composition dependent. This indicates that the additives used in the present study influences the structure of the a-Se. Specific heat and atomic mass values of the additive elements are found to be significant for the explanation of present results.

The paper builds on recent approaches in institutional theory on the co-existence of logics to analyse how field actors handle competing institutional demands in their practices. Business schools’ reactions to the critique that their research is not sufficiently relevant is analysed empirically. The logic of research in professional schools has been suggested as an alternative logic which is supposed to produce more relevant research than is possible under the logic that nowadays dominates management science in business schools: the logic of basic research. A contribution is made to institutional theory by showing how these two logics, even though competing, co-exist on the field level. The results of this exploratory study indicate that management scholars contribute to the co-existence of competing logics by separating the social spheres associated with a particular logic from each other, and by symbolically referring to a conflicting demand. The analysis of publication practices suggests decoupling as an underlying mechanism enabling the co-existence of two competing logics in the field of management science.

Prior research suggests that alliances created between retailers provide numerous benefits for their members which result in higher retail performance. The paper investigates whether the size of a firm is a moderating variable and/or an alternative explanation in studying the effect of alliance membership on the retailer’s performance. An empirical study, based on a small-scale survey, was carried out among 99 small-and medium-sized retailers in Hungary. Not only the strength but also the form of the relationship between alliance membership, performance and firm size have been investigated. Findings of the research support that firm size changes the form of causal relationship between alliance and performance of a retailer. Size contributes substantially to the variation of retail performance and increases the impact of alliance membership on sales and profit growth of retailers.

The aim of this review paper is to illustrate the areas of interest and the thinking of Hungarian hospital managers by providing a summary of the relevant Hungarian health care controlling literature and to give an introduction of potential research directions. The paper summarizes the “public discourse” and thinking on controlling, and simultaneously highlights the priorities of health care as well. The main range of interest are the financing problems and their solutions, as well as other kind of uncertainty arising from the continuous changes in roles and measures. In the early ninties some health care institutions started to apply controlling systems as a result of the introduction of performance-based financing and often published articles about it up to 2004. In 2015, a project created to enhance the operational efficiency of the health care system restarted controlling thinking: unified management measures required for hospitals may induce the development of the controlling data service, more accurate reporting, management attention, and experience sharing.

Sustainability as a driver for corporate economic success

Consequences for the development of sustainability management control

Society and Economy
Author: Stefan Schaltegger

Sustainability issues create opportunities and threats to business success. This paper discusses drivers to create a business case for sustainability and argues for a more systematic approach to management than current approaches which in practice involve working with checklists. Based on the core logic of the Sustainability Balanced Scorecard (SBSC) perspectives, a structure for sustainability management control is discussed.

The article introduces a research that examined the impact of family on the cooperation of individual family members in family-owned businesses by applying a theoretical framework based on family therapy, family business research and social value research. Firstly, it presents a model based on blending family therapy and social research on the individual’s value preferences with the aim of exploring the internal structure of this family effect. It also shows a possible family business consulting method in order to observe and handle the dynamics of this internal structure. Then, testing of the described model and consulting method is conducted by multiple-embedded case study research. Based on the results, refining statements are formulated regarding the applicability of family therapy in family business consulting and social value research.

This paper discusses why change inevitably leads to conflicts which, unless treated right, become destructive. It presents a tested framework on how to convert destructive conflicts into becoming constructive, which applies to individuals, families, any organizations, and society. The paper is based on the speech delivered by the author at the receipt of the Doctor Honoris Causa title of Corvinus University Budapest on the 22nd of January 2010.

Time is in constant motion: the present, the future and the past, although they are not concepts having a fixed meaning, they are present in everyday life both at the conscious and the unconscious levels. The author’s intention in this paper is to grasp the relationship of companies to time and to the future in the mature and nascent states of their life cycles. As discussed in this paper, this relationship may appear with little reflection in the form of assumptions in the eyes of strategy researchers and practitioners. At first the interrelatedness of theory and practice is discussed in order to focus on the role of scholars and practitioners in creating theory and putting it to practice or vice versa. This general introduction will lay the ground for the study of interpretations of the future and time from the perspective of strategy research and strategy practice, respectively.

This paper seeks to illuminate empirically a class of drivers of firm performance hitherto neglected in the economic literature. To accomplish this objective, we distinguished three elements: sales volume, participation in technology alliancing, and successful patent issuing. Our findings suggest that competitive pressure posed by larger rivals in an industry affects sales performance negatively, but the possession of absorptive capacity can counter this deleterious effect. Findings regarding the effects caused by a product portfolio with high technological content are mixed. Depending on the performance measure applied, the results show evidence of adverse outcomes for sales, U-shaped effects for participation in technology alliancing and inverted U-shaped results for patenting. We obtained our raw data from the 2006 and 2008 PITEC database, which is the Spanish equivalent of the EU Community Innovation Survey. Our sample embraces more than 3000 firms.
