AbstractNumerical taxonomy's claims for numerical phyogenetic inferences—i.e. various authors' contributions included in Sneath and Sokal's new textbook— re critically examined, and contrasted with Hennig's hylogenetic systematics. Numerical phyletics is found to be vague, inconsistent, and defective concerning the precision and power of problem solution in theory and practice. Therefore, in all these aspects it is inferior to Hennig's phylogenetic systematics, which seem to have been misunderstood and misinterpreted by Sneath and Sokal, apparently due to lack of sufficient information about the present state of this methodology.

Mobile Ad Hoc

The e-learning induction model that is well informed by the theory and practice is a sure way of being responsive to the dynamism of educational technologies. Common problem that must be taken as consideration and must be resolved in urban areas and the organization is an efficient message delivery in (MANET) Mobile Ad hoc Network. To get good and efficient communication, an algorithm must pay attention to several aspects such as the density of neighbouring node, shape and network size, channel priority level and used of message. Some previous studies attempted to propose solutions for delivering messages, but finding the optimal problem solution that will be use is very difficult.  In our research, we sugested an optimization on MANET by using an EA. The algorithm will provide several solutions to the problem of sending messages to MANET. Our goal is able to determine the optimal communication strategy for each node in network. By using (EA) evolutionary algorithm in  (n-2) network simulator, we found that result is promising for message delivery optimization to destination for using in system Elearning model networkKeywords: MANET, evolutionary algorithm, message delivery optimization.

Baccalaureate Nursing Program

An innovative project which aims to balance acute care and community health care in the clinical experience for students in a generic baccalaureate nursing program, is outlined. The ways in which nurses in community practice and academia can work together to ensure that primary health care (PHC) becomes a philosophy used for guiding nursing practice, is demonstrated. The aims of the project are to gather sufficient information on which to base curricula change to the undergraduate baccalaureate nursing program, as well as to assess the employment outcomes for this group of graduate nurses. The paper sets the context for the project by providing a brief historical review that highlights the relevance and necessity of PHC as a framework for nursing. The ways in which nurses in community practice and nurses in academia can work together to ensure that primary health care (PHC) becomes a philosophy used for guiding nursing practice is discussed. Through an innovative partnership between the School of Nursing, Flinders University of South Australia (FUSA) and Noarlunga Health Services, curriculum changes ensure that nursing students experience a balance of theory and practice in both the community and acute clinical fields, and that the curriculum is underpinned by PHC philosophy and principles.

Critical Scrutiny

Occupational therapists are increasingly embracing qualitative research methods yet little published advice exists in the occupational therapy literature to enable readers to gauge the quality and relevance of researchers' work. If qualitative research is to provide convincing evidence with which to inform theory and practice, it must be capable of withstanding critical scrutiny and practitioners must be given sufficient information with which to evaluate the strength and plausibility of the evidence reported. The process of undertaking qualitative research and of writing and critiquing subsequent reports is not about assessing adherence to rigid rules but of ensuring the appropriateness and thoroughness of data collection, analysis and reporting, given the nature and context of the issue. The espousal of a client-centred ethic also demands consideration of research relevance and usefulness to clients and the degree of consumer involvement throughout the research process. This paper examines an evaluative framework that may be used to assess the quality of qualitative evidence as this is both researched and reported. Recourse to a set of general strategies — used where appropriate – will serve to enhance the quality of qualitative research and assert its potential to inform the client-centred, evidence-based practice of occupational therapy.

Purpose: The aim of the paper is to identify effective ways of architectural form making of public facilities using an ecological approach. This is due to a new role of architecture in the urban sustainable development through the creation of aesthetically attractive and functional comfortable and safe environment. A special attention is paid to economic efficiency of objects, namely cost reduction in building construction and operation. This goal can be achieved through the improvement of design and construction technologies, development of the construction material industry, and interdisciplinary approach to the problem solution which implies the collaboration of specialists. Methodology/approach: Analytical, synergetic and inductive approaches are used in these studies. Based on the identification of particular cases of the new approach to the application of living nature in architecture and construction and their analysis and systematization, an algorithm of creating architectural objects is developed using natural technologies. The fields of their application are indicated within the architectural theory and practice. Form making experiments are carried out using natural technologies utilized by foreign specialists. Findings: Natural technologies can be systemized in the following way: – a living being as a prototype of an architectural object (external form, architectural bionics); – construction technology used by a living being as a prototype of building technologies in architecture (principle of space organization and structure formation); – a living being as a builder of architectural objects (e.g. use of bacteria as a building material); – a living being as a source of building material (objects produced by living beings, such as shells, chitin, silk thread, etc.). It is found that this approach is being intensively developed by foreign architects and designers jointly with other specialists (engineers, biologists, etc.), but has no spheres of application as well as related centers in Russia. Results: Natural technologies are very important for the transition to a model of sustainable urban development, since their use improves the ecological situation, provides efficient use of natural resources and reduces construction costs. A research group should be created for studying the foreign experience in using natural technologies for the development of research program on implementing this approach in Russia. Practical implications: Research results can be readily used for subsequent studies on similar or related topics; in the academic process for training architects; in real design of ecoarchitectural creative spaces and objects, which will positively affect the development of green economy in Russia. This approach can be applied in different regions and climatic zones of the world with its adaptation to local conditions, because it is a universal design method with mandatory application of the creative approach. Originality/value: The originality of research lies in the architectural typology modification connected with form making, planning and design concepts. Systematization of local knowledge and experiments is provided by construction materials and technologies. Theorization of the new pre-design and design methods can be identified as a natural technology approach.

The purpose of this study is to evaluate the opinions of physical education teachers on the concept of sportsmanship. This study, which has been based on the qualitative research paradigm, involves opinions of 13 physical education teachers (9 males and 4 females) which serve in public schools of Turkey and which have been specified through a critical incident sampling. A “semi-structured interview form” which has been developed using a literature review and expert opinions has been used to collect data. The descriptive analysis technique was used in analyzing the obtained data. Results of the study showed that physical education teachers have different views on the sportsmanship concept. Although physical education teachers stated their opinions on requirement of activities towards enhancing the awareness with regard to the sportsmanship concept in schools they work in, it was determined that they performed few activities pertaining to sportsmanship. However, it was seen that the current physical education course programs do not provide teachers with sufficient information regarding the sportsmanship education and that teachers desire to have education on the sportsmanship concept during in-service training activities. Furthermore, the involved teachers think that quality of the current university education in terms of the sportsmanship concept should be improved. In conclusion, in order to enhance the quality of physical education teachers with regard to the sportsmanship concept, particularly faculties of education are recommended to include compulsory courses containing both the theory and practice on sportsmanship and researchers are recommended to develop sample activities and practice guiding physical education teachers.

In the article, the definitions “castle in a state of long-term ruin” and “architectural revitalization” are given. A list of measures aimed at preserving architectural monuments from the standpoint of their application on castles in a state of long-term ruin is considered. The definitions characterizing permissible activities on architectural monuments specified in the Law of Ukraine “On the Protection of Cultural Heritage” and restoration State Building Standards, however, in theory and practice, much more concepts are used, since the regulated terms do not cover the entire range of possibilities for the preservation and development of architectural monuments. In their works, M. Bevz, A. Rybchynskyi, O. Plamenytska, P. Molski highlight measures for the preservation of architectural monuments. Analyzing the history of the founding of defensive castles, their further restructuring and decline, we form a definition: a castle in a state of long-term ruin is a castle, as a result of destruction during a siege or loss of its defensive functions in the 16th-17th centuries was abandoned without acquiring new owners fell and came to the state of ruin that we can observe today. Looking at conservation measures using the example of castles in a state of long-term ruin, we state the following positions: The conservation method is the main point for keeping castles in a state of long-term ruin. The restoration can only be applied fragmentarily, since a holistic restoration is akin to restoration, which is an unacceptable step, given the lack of sufficient information about the original appearance of the structure. Museumification is excellent, as a method of bringing a castle in ruins to a state suitable for an excursion visit, as well as designation, as a subspecies of museumification, accompanied by both information stands and tracing of foundations reveals the planning structure of the monument. Revitalization measures aimed at revitalizing the degraded space, and renovations, which give an authentic building a touch of novelty and emphasize the period of intervention in the monument are also important. In general, the idea of preserving the castle in a state of long-term ruin should be based on three main positions such as conservation, fragmentary restoration and revitalization, that is, preserving the authentic component and returning life to the object.
