In Senegal, Mosses constitute a large and diverse systematic group. This work is a contribution to the knowledge of Bryophyta in the herbaria of Senegal. It specifically proposes to determine the structure of the Bryophyta on the prospected sites in order to provide basic knowledge for a better sustainable management. This study is carried out in the first place in the herbaria of the University Cheikh Anta Diop of Dakar/Senegal: the herbarium of the Institut Fondamental d'Afrique Noire Cheikh Anta Diop (IFAN) and the herbarium DAKAR of the Department of Plant Biology of the Faculty of Sciences and Techniques. Secondly, a consultation of different checklists and databases was conducted to collect more information. This research work on the flora of the mosses allowed us to identify a total of 70 species divided into 44 genera, 24 families and 12 orders. The orders Hypnales, Dicranales and Hookeriales are the most represented. Bryaceae are dominant followed by Pottiaceae, Calymperaceae, Dicranaceae and Hypnaceae. The genera Fissidens, Calymperes, Bryum, Gemmabruym and Leucoloma are more diversified. These results are important for the conservation of the environment and the enhancement of plant biodiversity in Senegal.

The present article is dedicated to the problems of the organization and planning of scientific and research work of students of the University in English classes, gives grounds for the purposes and tasks of such competence-forming activity as part of the “Oriental studies” speciality program, the Russian State University for the Humanities. The article analyzes these competences, as well as forms and methods of their formation and development. The author presents demarcation of scientific knowledge and gives its characteristics: using most general qualities of a subject, objective reasoning, argumentativeness, results verifiability and reproducibility, consistency, practicality, capability to change, anticipating the future, making forecasts, methodological reflection. The author tried to analyze the reflexive component of scientific and research work of students in more detail. The article presents possible reflexive positions in the interaction between the teacher and the student and shows the dynamics of this interaction, i.e. gives a hierarchy of positions which the student can occupy in the educational process depending on how independent they are in their activity. The article also highlights the content of scientific and research work of students of the University in English classes on the basis of work with foreign texts in the macro-discourse for the “Oriental studies” speciality. The given foundations of the organization and content of scientific and research work of students have been regularly used in English language classes, as well as in optional forms of scientific activity. The students have shown good results and passion for this kind of work, which confirms the correctness of this approach.

The burgeoning area of plant genetics may hold the key to overcoming some of the most pressing environmental challenges. For example, crops can be genetically improved to make them better able to adapt to climate change, while genetic engineering of crops could help to address food security challenges. As such, a comprehensive understanding of plant genetics may enable humankind to make headway in addressing climate change and resulting challenges. Research in this area is therefore paramount. Research work undertaken in the Plant Transgenic Design Initiative (PTraD) in the Gene Research Center (GRC) within Tsukuba Plant Innovation Research Center (T-PIRC), located at the University of Tsukuba in Japan, is focused on plant sciences and biotechnologies. The PTraD is the centre of excellence in plant biotechnology research in Japan, shedding light on plant genetics and how this can be harnessed to solve environmental challenges such as climate change.

In October 1968, the University of Ghana commenced an extensive program in African archaeology. Graduate students from overseas are eligible to enroll for courses at the University, though no scholarships are presently available for non-Ghanaians. The Department of Archaeology of the University of Ghana was established in 1951 under the professorship of A. W. Lawrence. It presently has a senior teaching establishment of four together with a curator and two senior research fellows under the chairmanship of Professor Merrick Posnansky. The Department has a small specialist library, a museum, laboratory, dark room, workshops, and a team of trained technical staff. Most of the Department's research work is normally conducted in the dry season from November to May each year. In the past Professor Oliver Davies, author of the Quaternary of the Guinea Coast (1964) and West Africa before the Europeans (1967), conducted extensive fieldwork relating to the Stone Age and neolithic periods of Ghana's past and made large surface collections from all parts of Ghana which provide a rich topographical source of information on archaeology in Ghana. The Department has conducted extensive excavations in Ghana and its research fellows are presently engaged in writing up the results of the Volta Basin Research Project, in which more than thirty sites have been excavated since 1963 in advance of the formation of a large lake consequent upon the construction of the Volta Dam. The majority of the excavated sites have been of Iron Age date. In September 1968, Mr. C. Flight commenced a new season of excavations at “Neolithic” rock shelter sites at Kintampo, where occupations and burials dated to the middle of the second millennium B.C. were uncovered in 1967. Other excavations conducted during 1968 included work by Mr. D. Calvocoressi at the funerary terracotta site of Ahinsan and by Mr. Duncan Mathewson at the seventeenth-century A.D. Gonja site of Jakpasere. In 1969 a training excavation will be conducted at Elmina on the sixteenth- to eighteenth-century A.D. town in the vicinity of the Portuguese castle.

The Rowett Institute for research on animal nutrition had its origin under a scheme for promoting scientific research in agriculture adopted by the Development Commission in 1911.The Governing Body, which originally consisted of an equal number of members appointed by the Court of the University of Aberdeen and the Governors of the North of Scotland College of Agriculture, was constituted in 1913. Within recent years it has been expanded to include persons nominated by the Secretary of State for Scotland, the Royal Society, the Royal Society of Edinburgh, the Agricultural Research Council, and the Medical Research Council. Research work was begun in temporary accommodation in Marischal College in 1914, under the direction of Dr John Boyd Orr—now Lord Boyd-Orr—who continued as Director until his retirement in 1945.

The contents of Education for Sustainable Development should be included in teachers’ initial and advanced training programs. A sustainable consciousness is one of the main foundations for determining the key competences for sustainability. However, there are not many empirical studies that deal with consciousness from education. In this context, the e-portfolio appears as a tool that promotes reflection and critical thinking, which are key competences for consciousness development. This work intends to propose a categorization system to extract types of consciousness and identify the levels of consciousness of teachers in training. For this research work, which is of an eminently qualitative nature, we have selected 25 e-portfolios of students (teachers in pre-service training) in the last year of the School of Education at the University of Macerata (Italy). The qualitative methodological procedure that was followed enabled deducing three bases that shape the consciousness of teachers in training: thinking, representation of reality, and type of consciousness. We concluded that the attainment of a sustainable consciousness in teachers requires activating and developing higher levels of thinking, as well as a projective and macrostructural representation of reality.

Regardless of the discipline or institution in which scientific research will be conducted, the "method» is present. It remains fundamental of all research work that can inevitably affect problem-solving, development of the nation, and threaten quality of life. This is an exploratory study on research methods used in graduation projects in the following disciplines (health sciences, engineering, biological and agronomic sciences, and social sciences). The method used in this work is based on:(a) semi-structured survey by interviewing supervisors of final dissertations and theses in different selected disciplines (b) systematic analysis of the fifty-research work of graduate students. The works obtained from the libraries of the University Hassan II of Casablanca in different disciplines, submitted between 2014 and 2018. The parts of the empirical phase were analyzed, according to the processes and concepts of each discipline, to highlight the elements of the research method. The findings indicated the influence of the national scientific production by the design of the research method. The data collection and analysis are the sections that may affect the integrity of the research method. Our contribution is to remedy the standardization of the method and adapting it to the contexts of the needs of different disciplines.
