Succession Planning and Generational Transition: The Greatest Challenges for Family-owned Businesses

The purpose of the article is to describe problems connected with succession and generational transition in family-owned businesses. The author examines how family-owned businesses can be characterized along with the general position of family companies in the economy. The strengths of the article are that the author completes theoretical findings with real examples of family-owned businesses and case studies. He also makes use of the latest findings of a dissertation thesis focused on succession problems in small and medium-sized family enterprises. The solving of the question of succession in family businesses has been identified as the greatest problem and a proposal for solving this dilemma is analysed in detail in the article. The solving of the problem of succession is an interdisciplinary theme on the border between management and sociology. Family companies share numerous problems with non-family companies; however, family businesses differ from other kinds of businesses in that they have to come to terms with a generational transition in the leadership of the family business.

Authenticity, Reception and Media Reality

Authenticity, Reception and Media Reality This article deals with the reception of media reality, which is meant to be an alternative mode of consciousness, and with the phenomenon of authenticity and its understanding within media reality. It is also pointed out the distortion in the reception of media reality. As an unifying concept for media education and for the treatment of reception defects it is mentioned media anthropology - an interdisciplinary, respectively trans-disciplinary science, which can provide more consistent re-analyzing of the relationship between man and media as tools for improving his skills. From the methodological point of view the method of epistemological anarchism, Paul Feyerabend's "anything goes" is explained as an epistemological translation tool for developing reviewing competences and reception skills as a whole (organic reception). We propose to deal the distortion of media reception in different therapeutic ways: from sensory deprivation, through media substitution, organic reception, to transcendence of the observer and imitation of media - meta-creation. In the sense of organic, systemic reception we in fact propose to "copy" the communication strategy of media system(s) in order to extend or set appropriate "epistemic" competences. In the related illustration of this mechanism, the theory of A. Weinstock is applied for setting a research indifference point in the middle of a fictive reception continuum of polarities sympathy and antipathy with media. This paper represents a part of activities, which summarize author's dissertation thesis Reception instruction in the media reality, where there are presented not only analyses and attempted typology of reception instructions, but also case studies with specific proposals for teaching and researching within areas of media ethics and media education.

Contribution of Jānis Lielmanis in plant breeding in Latvia

Contribution of Jānis Lielmanis in plant breeding in Latvia In autumn 1922, the Ministry of Agriculture of Latvia delegated agronomist Jānis Hilarijs Lielmanis (1895-1970) to organise and establish the State Stende Breeding Station. For many years, he was a director (1922-1940) and later a researcher (1945-1956) of the State Stende Breeding Station. Under the guidance of Lielmanis, an infrastructure for breeding work was formed and research into the morphological, biological, and economic traits of local plant varieties obtained from different Latvian regions were begun in the station. Already in 1924, breeders started breeding of cereals, peas, flax, potato, and clover, using selection from local and foreign varieties and also hybridisation. Until 1945, breeders in Stende, under the guidance of Jānis Lielmanis, developed 16 plant varieties, in the period from 1945 to 1960 — 19 varieties. Parallel to his work in Stende, Lielmanis delivered lectures on plant breeding at the University of Latvia (1933-1940) and lectures on genetics, breeding, and seed production at the Latvian University of Agriculture (1940-1944, then Jelgava Academy of Agriculture; 1945-1948). In the later part of his life, Lielmanis worked in the Latvian Scientific Research Institute of Agriculture (1957-1970), where he conducted research in crop farming and breeding of red clover using traditional breeding methods, as well as polyploidy and heterosis methods, which was modern for that time. The research results of oat growth and acclimatisation were summarised by Lielmanis in his habilitation paper (1933), and the results of breeding and growth of red clover — in his dissertation thesis. He was awarded a degree of candidate of agricultural sciences in 1957 and a doctoral degree in 1968. He was very principled in his scientific viewpoints; he supervised five doctoral theses written by candidates of agricultural sciences, published 457 scientific and popular-scientific articles, and wrote six books. Taking into consideration the contribution of Lielmanis to Latvian agricultural science, in 1995, the Jānis Lielmanis award was established, which has been received by breeders, breeding groups, and seed producers for their contribution in plant breeding and seed production in Latvia.

Smoking Cessation Behavior in Male Portuguese Californians

The purpose of this study was to identify determinants of smoking cessation in a sample of male Portuguese Californians using data from the Portuguese Study, a dissertation thesis study with a crosssectional design that assessed 141 smokers and 67 ex-smokers of Portuguese origin residing in Southern and Central California recruited from Portuguese community clubs. Socio-demographics, acculturation, health beliefs, stress, and social support for smoking cessation were assessed and measured in this population. Bivariate predictors of becoming an ex-smoker were being married (p=.01), having a high support index for not smoking (p

Implementation of the e-Bug Project in Greece

The e-Bug pack and web site educational material has been translated and adapted to the Greek language and educational background, and implemented throughout Greece as a supplementary educational resource in elementary and junior high schools. Elementary and junior high school teachers in Greece have actively participated in the development of the e-Bug educational resource and supported the implementation of all e-Bug activities. Dissemination to all key national stakeholders has been undertaken, and endorsement has been obtained from educational and medical associations, societies and institutions. Independent evaluation has been carried out, as part of dissertation thesis projects, for postgraduate studies. The e-Bug educational resource provides all the essentials for the dissemination of good health behaviours in hygiene, monitoring the spread of infection and the prudent use of antibiotics, to the youth of this country. Its contribution is expected to be evident in the next adult generation.

Reply to the commentary by Berry-Stölzle and Born

This comment by T. Berry-Stolzle and P. Born does not refer to an article, but (1) to a summary of a talk published in German language in a conference proceeding and (2) to an unpublished working paper. We acknowledge the comment and find it important to give the works of Berry-Stolzle and Born the necessary credit. Clearly, the unpublished working paper by Berry-Stolzle and Born and the dissertation thesis of Berry-Stolzle have a relation to our working paper and the talk we gave at the annual congress of the German Insurance Science Association. It will thus be integrated in a revised version of the working paper. However, what we need to reject is the critique that we blatantly ignored their work. We have indicated that we have not knowingly ignored their work in two phone calls with the authors after receiving their comment and both have accepted this point. We thus regret to read this critique in this comment.

Managing Variety and New Product Introduction in Consumer Electronics Manufacturing Industry

This Dissertation Thesis provides a comprehensive understanding of the efforts undertaken by different players in the consumer electronics manufacturing industry in managing variety. Different kinds of product design efforts (such as QFD, DFV, modularity etc) in the new product introduction process paves the way to company-led/internal variety creation. Moreover, mass customization in association with build-to-order and postponement principles has been discussed as a way of creating customer-led/external variety. A framework has been developed which shows the functions of different players in the consumer electronics industry such as EMS (Electronics Manufacturing Service), OEM (Original Equipment Manufacturer) and OBN (Original Brand Name) companies, and their relationship and collaborative effort in creating new product through different design initiatives in the NPI process as well as, mass customization efforts to create varieties of products for customers. Links have been established between NPI and internal variety as well as, between mass customization and external variety. Three OBN companies (Samsung, Acer, and Dell) have been analyzed to understand the overall scenario.

Knowledge has legs: personal knowledge strategies shape the future of knowledge work and knowledge management

PurposeThe purpose of this paper is to mobilize organizations to look at knowledge management through the lens of the individuals whose knowledge they covet and to seek to leverage in order to establish a faster, more flexible and mutually supportive conduit to relevant knowledge and more sustainable knowledge contributions.Design/methodology/approachThis is a discussion paper based on the authors' recent dissertation thesis: “A theoretical model of knowledge strategies for professionals in volatile business settings”.FindingsOrganizations can no longer promise lifelong employment even to their best employees. Striving to safeguard employability instead, organizations and individuals can recalibrate the contributive value of their knowledge in a mutually‐ beneficial way even in short‐term, medium‐term or highly volatile employment settings. The resulting bottom‐up approach for managing personal knowledge reduces the friction and mistrust often associated with top‐down knowledge management. It sets the stage for an environment that manages for knowledge, both individually and collectively.Originality/valueSome individuals have learned to navigate the emerging knowledge economy successfully and craft sustainable value propositions for themselves based on what they know. The research identified the concept of knowledge empowerment and six knowledge strategies and their supporting elements as key enablers for this success. One of these strategies – Lifelong Learning – is explored in detail to demonstrate the transformational power of an additional vantage point that considers individuals as stakeholders and not just as contributors in the knowledge quest. This resets the responsibility for knowledge acquisition, creation and leverage and establishes the need for more extensive personal knowledge management as a subset of organizational knowledge management. This aspect of knowledge management has only been marginally explored in the knowledge management literature to date.

The dawn of the information age in least developed countries (LDCs): lessons learned from four case studies

The emerging information age is characterised by the ubiquitous availability of information and communication technologies. While in highly developed countries, due to heavy investments in the telecommunication infrastructure, the public and scientific discussion more and more focuses on the so-called digital divide 2.0, i.e. the lack of ICT skills, for developing countries both, the access to and the use of ICTs still remain a huge challenge. The goal of my dissertation thesis is to highlight these challenges, as well as the opportunities that occur for Least Developed Countries (LDCs) on their way towards an information society. The study examines ICTs in four geographically and culturally diverse regions, including the countries Yemen, Guatemala, Malawi and Lao PDR, on the macro and on the micro level. The research on the macro level is guided by the central research question: Are ICTs in LDCs used to foster societal development or are they reinforcing imperialistic patterns of Western hegemony?On the micro level the project aims to investigate the users’ demographics, their habits of ICT use, as well as the barriers and opportunities for the citizens emerging from the upcoming information age. The findings from the macro and the micro level will be correlated on the basis of the five dimensions of society (ecological, political, cultural, economical and technological) to assess the state of the art and to formulate strategies to counter the current eColonialism tendencies and to foster a sustainable implementation of ICTs in LDCs.

T10-O-17 Teaching sexology in Romania

Several years, there were only discrete and isolated attempts to teach and practice sexology. There were mostly courses regarding contraception and endocrinology. Mass media had a huge impact in enlightenment of Romanians regarding sexual issues. Few private practices of couple therapy and sexology have been established recently. to present the history of Sexology in Romania and to describe the stages of the development of sexology master classes within the University of Medicine Cluj Napoca, Romania The milestones of this teaching method have been put in 2005 by isolated courses of sexology, which raised the need for the development for a structured theoretical multidisciplinary approach and problem solving training. The two semester master classes of sexology gather specialists from various fields: physiology, dermatology and STD, gynecology, endocrinology, psychiatry, internal medicine, urology and andrology, forensic medicine, psychotherapy, philosophy. The balance between theoretical knowledge and practical skills is adapted on request of the students, which finish their studies with a dissertation thesis. The two years experience enables us to reanalyze the actual problems: to identify the gaps in the field and to reinforce the successful themes. The need for qualified specialists in sexology will be covered only in conjunction with similar initiatives on national level, and international wide.

Creating line defects with a single micro-sphere width in a DNA-linked 2D colloidal crystal array using a pulsed laser

A creation of micron-size narrow line defects in 2D colloidal crystal array was successfully accomplished using a focused pulsed laser. The 2D colloidal crystal arrays were obtained by a convective assembly of polystyrene latex micro-spheres (1.8 μm) and then immobilized onto the glass substrate by DNA hybridization process. To release a micro-sphere from the crystal, a focused laser beam was utilized to de-hybridize the DNA by raising the temperature above its melting point. From previous studies (Geiss E, Fabrication and defect design in two-dimensional colloidal photonic crystals. Ph.D dissertation thesis, 2003; Kim et al., Mater Sci Eng 26:1401–1407, 2006; Geiss et al., sudmitted), using a continuous argon ion laser, 514 nm, line-writing in colloidal crystal with 2–4 micro-sphere widths were achieved. In this study using the Nd:YAG pulsed laser’s second harmonic, 532 nm, line-writing of 1 micro-sphere width was accomplished. The presence of EB (ethidium bromide) dye that intercalates into the ds-DNA strands that bind the micro-spheres to the substrate facilitated the micro-sphere releasing process by reducing the laser energy required to release a micro-sphere. Factors that influenced controlled defect insertion were the medium containing the colloidal crystal, the dyes imposed on the crystal and the self-assembled micro-sphere groups. The most effective medium condition were determined at 1 mM global EB dye in 0.1 M NaCl for removing an individual micro-sphere in single micro-spheres, groups of micro-spheres and the close-packed arrays. Single micro-sphere width simple curves and corners in the photonic crystals were then created.

Social Aspects of Fur-rubbing in Cebus capucinus and C. apella

Capuchins rub particular plant materials into their pelage, a behavior for which most authors have proposed a medicinal function (Baker in American Journal of Primatology 38:263–270, 1996, Baker, M. (1998). Fur Rubbing as Evidence for Medicinal Plant Use by Capuchin Monkeys (Cebus capucinus): Ecological, Social, and Cognitive Aspects of the Behavior. Dissertation thesis. University of California Riverside; DeJoseph et al. in Journal of the American Academy of Dermatology 46:924–925, 2002). Individuals fur-rub solitarily or in groups, but researchers have not conducted studies to understand the differences. We investigated the link between the form of fur-rubbing and other social variables in 2 capuchin species. We supplied 2 captive groups —white-faced capuchins and tufted capuchins— with citrus fruit and onions and explored the behavioral processes and social aspects underlying the activity. We documented the occurrence, number of participants, and effect of recruitment behaviors in fur-rubbing subgroups. We investigated the role of kinship, affiliation, and dominance relationships in accounting for fur-rubbing groups. There is a significant difference in the form of fur-rubbing between white-faced and tufted capuchins. White-faced capuchins fur-rubbed mainly in subgroups and performed a particular behavior to recruit prospective participants, whereas tufted capuchins fur-rubbed mainly alone, and showed no particular motivation to be joined by other group members. White-faced capuchins could fur-rub together frequently, whatever their degree of kinship, affiliation, or dominance interval. In tufted capuchins, fur-rubbing appeared to be significantly affected by kinship and dominance.

Microstructure and Acoustical Macro-Behavior: Approach by Reconstruction of a Representative Elementary Cell

The fundamental issue of determining acoustic properties of porous media from their local geometry is examined in this Ph.D. dissertation thesis, thanks to a sample of open-cell aluminium foam analyzed by axial computed microtomography. Various geometric properties are measured to characterize the experimental sample at the cell size level. This is done in order to reconstruct a porous medium by means of idealized three- and two-dimensional unit cells. The frequency dependent thermal and velocity fields governing the propagation and dissipation of acoustic waves through rigid porous media are computed by Brownian motion simulation and the finite element method, respectively. Macroscopic behavior is derived by spatial averaging of the local fields. Our results are compared to experimental data obtained from impedance tube measurements. First, this approach leads to the identification of the macroscopic parameters involved in Pride and Lafarge semiphenomenological models. Second, it yields a direct access to thermal and viscous dynamic permeabilities. However, the bidimensional model underestimates the static viscous permeability as well as the viscous characteristic length; what thus require a three-dimensional implementation.

Dissertation Chapter 3: Why Normative Political Theories Depend on Ethical Theories

This Chapter elucidates and defends the third and final premise of the dissertation's argument. The premise defended here runs thus: Any theory claiming that a certain set of normative requirements ranges over (a) some actions, (b) some states of affairs, (c) some ways of life, or (d) some policies, the actualization of which would advance or set back the interests of persons, analytically depends on some theory claiming that a certain set of normative requirements ranges over (i) all actions, (ii) any states of affairs, (iii) any ways of life, (iv) any policies, or (v) any character traits, the actualization of which would advance or set back the interests of persons. We shall call this premise the Universal-Particular Thesis. The Thesis implies, first, that any theory of the first kind is a logical consequence of a theory of the second kind. It implies, second, that any theory of the first kind has the meanings of its theoretical terms shaped by the theory on which it depends. The Chapter defends this Thesis with an argument of three premises and one lemma. Parts 2-6 explicate the Thesis and defend each premise and the lemma. Part 7 reviews the argument to the Universal-Particular Thesis. Part 8 considers and replies to an objection to the Thesis. The objection is the famous meaning-change argument, due to Paul Feyerabend. It holds that the meanings of terms denoted by the same word differ across different theories. E.g., in classical mechanics means something different than mass in relativistic mechanics. Part 9 then proves the dissertation's thesis from the chapter Thesis and the theses of the previous Chapters. Part 10 concludes.

The "Bologna Process" may be an unusual vantage point from which to approach a review of the two Western works under consideration here. Each originated as a dissertation at a distinguished university in the United States for the degree of doctor of philosophy (Ph.D.). Each makes a contribution in its own way to the advancement of scholarship, but the differences in the measure and quality of contribution are so immense as to create wonderment that the same degree could be conferred on the authors within the same system of higher education. Of course, different universities, different standards, different examiners, perhaps different circumstances. But I remain more persuaded than previously that a two-cycle doctorate, as exists in the United Kingdom (e.g., in law: Ph.D. or D.Phil., LL.D.) and the Russian Federation (e.g., kandidat and doktor of legal sciences), should be introduced in the United States. The field of legal history in Russia is enjoying a renaissance as never before. The "civilian" legal historians (the term used by Russian lawyers for [End Page 657] historians of Russian law not trained as lawyers—on whose shoulders rested the immense documentary achievements of the Soviet era, by the way: the definitive texts of the Russkaia pravda, Sudebniki, Sobornoe ulozhenie, and others)—are belatedly being joined by the legal community in producing important works. The lawyers are mostly using their legal history as a source for contemporary law reform, and rightly so. Naturally their focus is on the normative substance of Russian rules and institutions—real law and legal reasoning—and less on the socio-economic dimension. Russian legal publishing houses (especially IurinfoR, Statut, and Zertsalo) have, with the support of the Russian Federation and the major legal commercial computer data bases, Garant and Konsul´tantplus, produced impressive series of reprints (not, as a rule, facsimile) in modern orthography and with substantial introductions (many translated in Sudebnik). These deserve notice in this journal in their own right. They are collectively changing the modern face of Russian legal history. Turning to the works under review, I begin with Dr. Whisenhunt's monograph on the role of Mikhail Mikhailovich Speranskii in the codification of Russian legislation, namely—and let us not understate the measure of achievement—the greatest systematization (Polnoe sobranie zakonov Rossiiskoi imperii [hereafter PSZ]) and codification (Svod zakonov Rossiiskoi imperii [hereafter SZ]) of legislation, in its day, on this planet and far ahead of anything commensurate in continental Europe, England, or the United States. I reviewed this work in isolation elsewhere,1 so it is perhaps slightly unfair for the author to have to endure the scalpel twice. Kritika, however, enjoys a different readership with different concerns. I also have reflected more on the work, having reread it for this review and had the benefit of seeing it against the other two books being considered here. Whether, as Whisenhunt undertakes to demonstrate, Marc Raeff was correct in characterizing the "compilation of the PSZ and SZ in the 1830s [sic]" as the "fullest expression of Speranskii's political ideas" sounds preposterous to a lawyer and is certainly bereft of any redeeming value as a dissertation thesis. Raeff will have had his own...

Über Vernetzungen im Mathematikunterricht — eine Untersuchung zu linearen Gleichungssystemen in der Sekundarstufe I

According to the TIMS-Study students in Germany show great deficits in problem solving abilities according to a lack of flexibility in thinking in mathematical networks. However, there exists hardly information about the exact lacks and the reasons of the deficits. The aim of the study in this dissertation thesis was to investigate how a mathematical network as it is presented in textbooks is transformed when carried over into students' minds during teaching and learning processes. The thesis subdivides into a theoretical part and the presentation of the empirical investigation. The theoretical part gives first an overview on the didactical discussion to the topic of connections in mathematics education. It follows a conceptual foundation of mathematical networks and their different aspects, pointing out that the underlying structure of a network is a graph, whose vertices represent mathematical objects and nonmathematical components related to these, and whose edges represent existing relations on them. According to the different sorts of relations, network categories with relevance for mathematics education in school are defined. Further, some theories and models describing aspects of genesis, memorizing and recalling connections are presented and information with regard to the different network categories defined above are brought out. The model of curricular frames is discussed as an approach to specify connections in teaching and learning processes; it serves, together with the modelling of connections as graphs, as aids for the empirical investigation. The empirical study particularly focuses on the topic "sets of two equations in straight form" in middle grade classes and restricts on the investigation of some network relations according to subject systematics and a special relation according to the application of mathematical objects, the model relation. The main research questions are: 1. Which relations according to subject systematics and which model relations to the topic focused on are part of curricular frames? 2. Which network transformations result in teaching and learning processes, on the way from the frame of the intended curriculum into the frame of the implemented curriculum and further in the frame of the achieved curriculum? The results show that connections as they are presented in text books are nearly unchanged translated into the frame of the implemented curriculum: teachers follow almost exactly the textbook in their lessons. On the further transfer of the implemented network into students' minds many connections are filtered out: the mainly learned connections by students are part of the links according to subject systematics (links between problems and solving algorithms, linkages according to a subconcept-superconcept relation), model links are hardly known. Students show great difficulties, when they have to use connections in problem solving processes. The study reveals the incompleteness of the transfer of implemented networks into students' minds. Moreover, the missing relations in the achieved networks are pointed out. The results of the study provide useful information for a possible improvement of teaching and learning processes with respect to the different sorts of connections.
