A tanulmány amellett érvel, hogy az adaptív mechanizmusoknak és diszfunkcióiknak a finom elemzése jelentősen hozzájárul a fejlődés és a betegségek jobb megértéséhez, és a betegségek osztályozásának és a terápiáknak új útját nyithatja meg. Az evolúciós megközelítés a pszichoterápiába nem új elméletet vagy terápiás megközelítést kíván bevezetni, hanem az emberi természet törvényszerűségei mentén új megértési stratégiákat javasol. A patológiás szerveződést alapvetően az adaptivitás dimenziójában gondolja el. Ez kikényszeríti a fejlődési történet és a multikauzalitás szem előtt tartását. Hosszú távon ez a tüneti kategorizáción alapuló diagnosztika újragondolását is jelenti.

Management Accounting System

Our study covered the development and evolution of the management accounting system of a subsidiary company in a group. Our study was a longitudinal one starting from the incorporation of the company. We divided this period into five stages according to the major events happened, namely the formation of the company, the invoicing crisis, the conflict with parent company, the conflict with fellow subsidiaries, and the influence of the chief executive. In our analysis we applied the three dimensions of structure in the theory of structuration (i.e., signification, legitimation and domination). The structuration theory explained the emergence of certain phenomena and events that were not explained by traditional accounting theories. Many events in our study validated the core ideas of the structuration theory which composes of the concepts of structure, system and duality of structure. The phenomena suggested that structure was both the medium and outcome of the conduct it recursively organized. Other features of the theory, such as the dialectic of control and system contradiction, were also applicable

Development And Evolution

Alteration of β-catenin expression is involved in the development and evolution of hepatocellular carcinoma (HCC); β-catenin is able to influence tumor cell proliferation. We analyzed the immunohistochemical (IHC) expression of β-catenin on a group of 32 patients diagnosed with HCC using the anti-β-catenin monoclonal antibody (clone E247). We correlated the expression of β-catenin with the proliferation index of Ki-67 (PI Ki-67), the mitotic index (MI) and other clinical and pathological features. We observed an altered β-catenin expression in 58.38% of all HCC cases. This expression was insignificantly correlated with tumor size (]5 cm) (p = 0.683), histological grade G1-G2 (p = 0.307), vascular invasion (p = 0.299) and advanced pT stage (p = 0.453); we obtained a significantly higher MI in HCC with altered β-catenin expression (p = 0.018), as compared to HCC without overexpression (1.66 � 1.37) (p = 0.038) and a PI Ki-67 of 22.49 � 20.1 and 28.24 � 18.2, respectively in tumors with altered β-catenin expression with insignificant differences compared to HCC without overexpression (25.95 � 15.2) (p = 0.682 and p = 0.731, respectively). According to the results we obtained, aberrant β-catenin expression in HCC was correlated with a high mitotic index, therefore playing an important role in tumor progression by stimulating tumor cell proliferation; non-nuclear β-catenin overexpression can have a pathological significance in HCC, especially in cases of HCC associated with hepatitis B virus (HBV) infection.

This chapter proposes a theory of moral regression, arguing that inclusivist gains can be eroded not only if certain harsh biological and social conditions indicative of out-group threat actually reappear but also if significant numbers of people come to believe that such harsh conditions exist even when they do not. It argues that normal cognitive biases in conjunction with defective social-epistemic practices can cause people wrongly to believe that such harsh conditions exist, thus triggering the development and evolution of exclusivist moralities and the dismantling of inclusivist ones. Armed with detailed knowledge of the biological and social environments in which progressive moralities emerge and are sustained, as well as the conditions under which they are likely to be dismantled, human beings can take significant steps toward transforming the classic liberal faith in moral progress into a practical, empirically grounded hope.

Development And Evolution

The first comprehensive synthesis on development and evolution: it applies to all aspects of development, at all levels of organization and in all organisms, taking advantage of modern findings on behavior, genetics, endocrinology, molecular biology, evolutionary theory and phylogenetics to show the connections between developmental mechanisms and evolutionary change. This book solves key problems that have impeded a definitive synthesis in the past. It uses new concepts and specific examples to show how to relate environmentally sensitive development to the genetic theory of adaptive evolution and to explain major patterns of change. In this book development includes not only embryology and the ontogeny of morphology, sometimes portrayed inadequately as governed by "regulatory genes," but also behavioral development and physiological adaptation, where plasticity is mediated by genetically complex mechanisms like hormones and learning. The book shows how the universal qualities of phenotypes--modular organization and plasticity--facilitate both integration and change. Here you will learn why it is wrong to describe organisms as genetically programmed; why environmental induction is likely to be more important in evolution than random mutation; and why it is crucial to consider both selection and developmental mechanism in explanations of adaptive evolution. This book satisfies the need for a truly general book on development, plasticity and evolution that applies to living organisms in all of their life stages and environments. Using an immense compendium of examples on many kinds of organisms, from viruses and bacteria to higher plants and animals, it shows how the phenotype is reorganized during evolution to produce novelties, and how alternative phenotypes occupy a pivotal role as a phase of evolution that fosters diversification and speeds change. The arguments of this book call for a new view of the major themes of evolutionary biology, as shown in chapters on gradualism, homology, environmental induction, speciation, radiation, macroevolution, punctuation, and the maintenance of sex. No other treatment of development and evolution since Darwin's offers such a comprehensive and critical discussion of the relevant issues. Developmental Plasticity and Evolution is designed for biologists interested in the development and evolution of behavior, life-history patterns, ecology, physiology, morphology and speciation. It will also appeal to evolutionary paleontologists, anthropologists, psychologists, and teachers of general biology.

Development And Evolution

The problem of the repeated parts of organisms was at the center of the biological sciences as early as the first decades of the 19th century. Some concepts and theories (e.g., serial homology, unity of plan, or colonial theory) introduced in order to explain the similarity as well as the differences between the repeated structures of an organism were reused throughout the 19th and the 20th century, in spite of the fundamental changes during this long period that saw the diffusion of the evolutionary theory, the rise of experimental approaches, and the emergence of new fields and disciplines. Interestingly, this conceptual heritage was at the core of any attempt to unify the problems of inheritance, development, and evolution, in particular in the last decades, with the rise of “evo-devo.” This chapter examines the conditions of this theoretical continuity and the challenges it brings out for the current evolutionary sciences.
