    The Master's programme Industrial Ecology is jointly organised by Leiden University and Delft University of Technology - Biojet fuel is developed as a potentially more sustainable alternative to existing petroleum based jet fuels. To establish the environmental and social sustainability of the biojet fuel product system, the full life cycle of the production should be analyzed. The environmental LCA (ELCA)and social LCA (SLCA) have been developed as two independent tools, but they cannot be used to analyze the same product system as their system boundaries differ. This research studies the possibility of harmonizing the two tools into a single social and environmental LCA (SELCA) methodology in light of its use in the biojet fuel product system. SELCA was developed through an extensive literature review, followed by catering it to the biojet fuel product system based on a survey and a dummy case study. The ELCA is based on unit processes while the SLCA uses organizations as its base. To reconcile these two system elements, the organizations were treated as multifunctional processes that can be allocated to the product system. The DPSIR model was used to ensure that data on interventions and economic flows were equivalent to each other and capable of being causally connected to the product system. The resulting methodology has consistent system boundaries and data for both social and environmental impacts. The majority of existing SLCA characterization methods and indicators are not compatible with SELCA. Indicators must be based on DPSIR pressure level data and be capable of being aggregated for the product system in order to be comparable to ELCA indicators. Many SLCA methodologies are based on statistical data which conceptually cannot be attributed to a particular organization or unit process. The only operational methodology is that of Hunkeler (2006) which uses quantitative labor hour data. As a methodology for assessing the biojet fuel, SELCA has several limits. The existing indicators do not address all issues considered important by academia and the industry. Also, despite that SELCA can in principle include the full biojet product system, in practice it will be limited by the lack of background databases. This results in more cut-off points and smaller system boundaries as shown in the dummy case study. However, with further research and development of characterization methods and databases, SELCA has the potential to fully integrate the environmental and social impact assessments of the biojet fuel product system.Technology, Policy and ManagementEngineering, Systems and ServicesIndustrial Ecolog

    Смирнова Александра Вячеславовна, заместитель директора по учебно-воспитательной работе, средняя общеобразовательная школа № 119 с углубленным изучением английского языка Калининского района Санкт-Петербурга; аспирант кафедры иностранных языков, Санкт-Петербургская академия постдипломного педагогического образования, Санкт-Петербург, Россия. Aleksandra V. Smirnova, Deputy Director for Educational Work, Secondary School No. 119 with in-depth study of English, St. Petersburg; PhD student of the Department of Foreign Languages, St. Petersburg Academy of Postgraduate Pedagogical Education, Russia.В научно-педагогической литературе концепция научного образования С.И. Гессена представлена в единичных статьях отдельных исследователей, но в настоящее время она заслуживает пристального внимания ввиду ряда причин: наличия необходимости повышения уровня научной грамотности населения России; отсутствия общепринятой концепции научной грамотности в российской педагогике; необходимости разграничения понятий «естественнонаучная грамотность» и «научная грамотность»; отсутствия обоснованной модели формирования научной грамотности в процессе образования. Цель исследования – определить корреляцию понятий «естественнонаучная грамотность» и «научная грамотность» и значимости предлагаемого С.И. Гессеном практического воплощения научного образования в современных условиях. Задачи исследования – сопоставить современную концепцию научной грамотности с теорией научного образования С.И. Гессена и определить теоретический вклад данной теории в проблему разграничения понятий «научная грамотность» и «естественнонаучная грамотность». Основные положения теории научного образования С.И. Гессена сопоставлены с концепцией научной грамотности, представленной в научных работах Нормана Ледермана, профессора Технологического института штата Иллинойс, и рамочных документах международного исследования PISA. Выявлено сходство основных положений теории научного образования, разработанной С.И. Гессеном, и современных прагматических концепций научной грамотности. Этот вывод позволил нам опираться в нашем исследовании на философско- антропологический подход. Обоснованы разграничения двух видов грамотности: научной и естественнонаучной, выявили иерархическое отношение видов грамотности. Предложена модель структуры научной грамотности, базирующаяся на пяти компетенциях. In the literature, the concept of science education by S.I. Hessen is scarcely described, but at present it deserves close attention due to a number of reasons: the need to increase the level of scientific literacy of the Russian population; the absence of a generally accepted concept of scientific literacy in Russian pedagogy; the need to distinguish between the concepts of “natural science literacy” and “scientific literacy”; lack of a reasonable model for the formation of scientific literacy in the education process. The purpose of the study is to determine the correlation between the concepts of “natural science literacy” and “scientific literacy” and to define the significance of the practical implementation of scientific education proposed by S.I. Hessen in modern conditions. The objectives of the study are to compare the modern concept of scientific literacy with the theory of science education offered by S.I. Hessen and to determine the theoretical contribution of this theory to the problem of distinguishing between the concepts of “natural science literacy” and “scientific literacy”. I compared the main provisions of the theory of science education with the concept of scientific literacy, presented in the scientific works of Norman Lederman, professor at the Illinois Institute of Technology, and with the framework documents of the international PISA study. The author revealed the similarity of the main provisions of the theory of science education developed by S.I. Hessen, and modern pragmatic concepts of scientific literacy. This conclusion allowed us to rely in our study on the philosophical and anthropological approach. The author substantiated the distinction between two types of literacy: scientific literacy and natural science literacy. The hierarchical relationship of types of literacy was revealed. The author proposed a model of the structure of scientific literacy based on five competencies
