The article deals with the problem of improving the quality of training future navigators according to the strategic goals of the modernization of the educational process in Ukraine’s marine higher educational institutions, based on the humanistic paradigm, which requires special attention to the formation of future navigators’ communicative self-efficiency. The study of this problem is of particular relevance, since it is one of the main professional characteristics for representatives of the senior command navigators that enables them to carry out professional activities productively, adequately and at a high level: to organize the coordinated work of the crew, especially consisting of specialists of different nationalities, religious denominations, mentalities; competently and skilfully communicate with seaport employees, representatives of foreign companies, etc. The paper presents the conceptual provisions of A. Bandura, the founder of the theory of self-efficiency, its role and importance in person’s life as well as those of J. Caprari and D. Servon, D. Matsumoto (communication), educators (self-efficiency), (communicative self-efficiency) in the context of importance and the need to develop and form these phenomena for improving the quality of the training aimed at future navigators in higher education institutions of maritime profile. The phenomenon “communicative self-efficiency of the future navigators” has been defined; its essence and structure have been considered, the latter consisting of three components: reflexive (self-identification with navigators as model professionals, the presence of adequate self-assessment of their own actions in the field of professional communication, a stable reflexive position), cognitive-operational (awareness of the communicative sphere of maritime professional activity, skills, professional communication abilities); affective-behavioural (confidence in the possibility of productive communication in professional activities, emotionality, activity, responsibility, ability to self-regulate and self-sustain). The forms and methods for the formation of communicative self-efficiency of cadets of marine universities involved into the experiment have been presented: reflective workshop, keeping a reflective diary, which gave the cadet the opportunity to conduct self-analysis of their own professional actions and enhance self-understanding regarding the presence of the necessary professional personal qualities for performing their future professional activities effectively and building a positive Self-concept of the future navigator; the organizing dialogue “The role of the reflective component in developing future navigators’ communicative self-efficiency”, the technology “Developing confidence in self-efficiency and productive communication of future navigators in their future independent professional activities”, the training module “Communication skills”, etc. Keywords: communication, self-efficiency, communicative self-efficiency, future navigator, marine higher educational institution.

This article is devoted to the question of the Self-system role in the mental regulation of human states. It analyzes different approaches to the study of relationship between the structures of the Self-system and mental states of a person. The purpose of this work is to establish the relationship between the components of the Self-system and the level of effectiveness in self-regulation of students’ mental states. The research was carried out in three forms of educational activity, different in the tension level: at a lecture, a seminar and an exam. Here are shown the most typical mental states of students with different level of self-regulation efficiency in different forms of educational activity. It was revealed that students with a high level of self-regulation efficiency more intensively experience positive cognitive states, regardless of the educational activity intensity. It was found out that higher manifestations of positive components of selfattitude (self-confidence, self-worth) and lower indicators of internal conflict characterize students with high efficiency of mental states’ self-regulation and self-blame. It was revealed that students with a high level of self-regulation efficiency have a significantly higher level of expression of the self-system components. Were established the leading substructures of mental states and the self-system in each of the forms of students' educational activity. It was found out that in everyday forms of educational activity, the behavior indicator is of the greatest importance, and in a tense examination situation – somatic reactions and cognitive processes. It was shown that as the tension of the situation grows from lecture to exam, the role of the components of self-attitude in the regulation of both individual substructures and mental states of students’ increases.

Full textAbstract:
Different approaches in creating mechanisms for efficient public procurements have been applied worldwide over the last decade. Among these, bundling of public procurement is seen as a potential efficiency boost in the practice in highly decentralized procurement environments. Nevertheless, the domain of public procurement efficiency is still at its infancy in academic terms. This study examines the effects of centralization of public procurement at the local self-government level in Serbia. In particular, the study explores various upsides and downsides of centralization. Reflective recommendations provide a sound base for public procurement policy holders at the level of local self-governments.

Full textAbstract:
The growth of world population, limitation of resources, economic problems, and environmental issues force engineers to develop increasingly efficient solutions for logistic systems. Pure optimization for efficiency, however, has often led to technical solutions that are vulnerable to variations in supply and demand, and to perturbations. In contrast, nature already provides a large variety of efficient, flexible, and robust logistic solutions. Can we utilize biological principles to design systems, which can flexibly adapt to hardly predictable, fluctuating conditions? We propose a bio-inspired "BioLogistics" approach to deduce dynamic organization processes and principles of adaptive self-control from biological systems, and to transfer them to man-made logistics (including nanologistics), using principles of modularity, self-assembly, self-organization, and decentralized coordination. Conversely, logistic models can help revealing the logic of biological processes at the systems level.

Не відкладайте на потім те, що можна зробити вже прямо зараз. Ми часто чуємо цю фразу, але як в наше століття постійних змін встигати жити наповнено і при цьому не відставати від загального прогресу, постійно навчаючись, працюючи, займаючи свого часумаксимальною кількістю «корисних» справ? Особливо гостро ці питання стоять перед молоддю, а зокрема перед студентами. В цей період життя необхідно визначитися з професією, зі своїм місцем у світі, з планами на майбутнє, щоб закласти для них міцний фундамент. Однак при такій насиченості життя багато хто стикається з проявом такого феномена як прокрастинація, відкладаючи дійсно важливі справи і рішення. Це властивість властиво багатьом людям різного віку і категорій, але особливо масштабне поширення прокрастинація має серед учнів вузів. Актуальність даної теми обумовлена тим, що прокрастинація як проблема особистості значима для тих спільнот, які характеризуються орієнтацією на досягнення. Саме в таких умовах знаходиться більшість сучасних молодих людей. Вони постійно перебувають у умовах виконання зобов'язань, що вимагають дотримання термінів, в зокрема навчальні завдання. Вище сказане формує високий інтерес наукової спільноти до вивчення феномена прокрастинації. Про це свідчить кількість дослідницьких робіт, які демонструють взаємодію прокрастинації з різними психологічними феноменами. Наукова новизна одержаних результатів дослідження полягає в теоретичному й експериментальному дослідженні, що узагальнені і систематизувати підходи до вивчення феномена прокрастинації, а також виявлені причинно-наслідкові зв'язки між феноменами прокрастинації і різними психологічними особливостями особистості.
EN : The work is presented on 61 pages, 7 tables, 4 figures. The list of references includes 46 sources. Object of research: the phenomenon of procrastination. Don't put off what you can do right now. We often hear this phrase, but how in our century of constant change to have time to live life to the fullest and at the same time keep up with the overall progress, constantly learning, working, occupying his time with the maximum number of "useful" things? These issues are especially acute for young people, and in particular for students. During this period of life it is necessary to decide on a profession, with their place in the world, with plans for the future, to lay a solid foundation for them. However, with such a rich life, many people face the manifestation of such a phenomenon as procrastination, postponing really important matters and decisions. This property is characteristic of many people of different ages and categories, but procrastination is especially widespread among university students. The relevance of this topic is due to the fact that procrastination as a problem of personality is important for those communities that are characterized by a focus on achievement. It is in such conditions that most modern young people find themselves. They are constantly in a position of fulfillment of obligations that require compliance with deadlines, in particular educational tasks. The above forms a high interest of the scientific community in studying the phenomenon of procrastination. This is evidenced by the number of research papers that demonstrate the interaction of procrastination with various psychological phenomena. The scientific novelty of the obtained research results lies in the theoretical and experimental research that generalized and systematized approaches to the study of the phenomenon of procrastination, as well as the causal links between the phenomena of procrastination and various psychological characteristics of the individual.

Full textAbstract:
Abstract The chapter sets out to answer a question that has long been on the mind of policy-makers, university leaders, scholars and students: does international student credit mobility have a positive impact on graduate employability? Traditionally, this question has been answered using survey data where internationally mobile students self-report their employment situation at a certain point after graduation. According to these studies, international student mobility positively affects the labour market outcomes of students. For instance, the European Commission reports that: (1) students who completed an Erasmus mobility program are half as likely to face long-term unemployment; (2) the unemployment rate of Erasmus students is 23% lower five years after graduation (European Commission 2014). While these studies provide important insights about the benefits associated with the cross-border credit mobility of students, the results can be plagued by self-selection bias in reporting post-mobility employment outcomes. In order to avoid the problems associated with survey data, in this chapter we offer an analysis based on register data from university records and employment records, using as a case study the West University of Timisoara, a leading comprehensive university in Romania. Using register data offers the possibility to study population-level data and compare the employment outcomes of mobile and non-mobile students. The chapter analyses the impact of credit mobility on insertion in the labour market, income levels and occupational prestige. While the research question that the chapter is trying to answer is important, the main message of the chapter is broader: ministries and higher education institutions should release data for research purposes. Register data is readily available and helps researchers make efficient use of resources. In turn, this can encourage evidence-based policymaking.

The objective of the chapter is to analyze the determinants of participation and impact of microfinance on income, empowerment, and efficiency. The study is based on primary data based on the field survey conducted in Baripada block and Betanati of Mayurbhanj District of Odisha, India. For this study, a total of 400 households were covered, out of which 300 are participants and 100 are non-participants. Four participants are selected from each self-help group. The Functional Efficiency Index, Economic Empowerment Index, activity level correlates of functional efficiency and economic empowerment have been calculated. The study found that 28% of the total groups have a low level of functional efficiency while 42% of the groups have attained moderate level of functional efficiency and 30% of the groups have managed to reach a high level of functional efficiency. The result suggests that land holding, education, and participation are positively related to household income. The poorest section of the society, those who need at most attention, are not participating significantly in the program.

Full textAbstract:
Wireless Sensor Networks are the key-enabler for low cost ubiquitous applications in the area of homeland security, health-care, and environmental monitoring. A necessary prerequisite is reliable and efficient event detection in spite of sudden failures and environmental changes. Due to the fact that the sensors need to be low cost, they have only scarce resources leading to a certain level of failures of sensor nodes or sensing devices attached to the nodes. Available fault tolerant solutions are mainly customized approaches that revealed several shortcomings, particularly in adaptability and energy efficiency. The authors present a complete event detection concept including all necessary steps from formal event definition to autonomous device configuration. It features an event definition language that allows defining complex events as well as enhance the reliability by tailor-made voting schemes and application constraints. Based on that, this paper introduces a novel approach for self-adapting on-node and in-network processing, called Event Decision Tree (EDT). EDT autonomously adapts to available resources and environmental conditions, even though it requires to (re-)organize collaboration between neighboring nodes for evaluation. The authors’ approach achieves fine-grained event-related fault tolerance with configurable adaptation rate while enhancing maintainability and energy efficiency.

Full textAbstract:
While previous chapters described dyad-level and group-level behavioral processes of symbolic management, in this chapter we examine processes of symbolic management at a more micro-level of analysis. We describe a kind of self-regulated cognition in which managers and directors reflect on personal and social characteristics held in common with colleagues, and avoid thoughts about attributes not shared, prior to interaction. We explain how such cognitions increase the efficiency and efficacy of social influence behavior toward powerful colleagues within the firm, security analysts, and powerful institutional investors. We further describe how managers engage in self-regulated cognition about firm strategy and governance prior to social influence opportunities with security analysts and institutional investors, and how such cognitions enhance the efficacy of impression management. We also reveal important side benefits of self-regulated cognition, including reduced symptoms of burnout in top executives, and reduced interpersonal conflict in diverse top management teams.

Full textAbstract:
This work proposes and evaluates distributed algorithms for data clustering in self-organizing ad-hoc sensor networks with computational, connectivity, and power constraints. Self-organization is essential in environments with a large number of devices, because the resulting system cannot be configured and maintained by specific human adjustments on its single components. One of the benefits of in-network data clustering algorithms is the capability of the network to transmit only relevant, high level information, namely models, instead of large amounts of raw data, also reducing drastically energy consumption. For instance, a sensor network could directly identify or anticipate extreme environmental events such as tsunami, tornado or volcanic eruptions notifying only the alarm or its probability, rather than transmitting via satellite each single normal wave motion. The efficiency and efficacy of the methods is evaluated by simulation measuring network traffic, and comparing the generated models with ideal results returned by density-based clustering algorithms for centralized systems.

This chapter discusses ways in which the problem of phenomenal unity can be analyzed on the representationalist level of description. Having characterized phenomenal unity as a kind of holism in the previous chapter, the aim is now to determine how collections of (phenomenal) representations can be holistic and how this holism can make a phenomenal difference. The chapter is structured as follows. First, relevant features of the representationalist level of description are explained. This is followed by a discussion of how the experienced self can be analyzed in terms of a global self-representation, which constitutes a phenomenal point of view (an experienced first-person perspective). Then the question of how the existence of a hierarchy of experienced wholes can be justified on purely theoretical grounds is explored, by asking how a hierarchy of representation increases the efficiency of the system. Finally, it is suggested that measures of (dynamical) complexity, like causal density and integrated information, could be used to operationalize the notion of representational holism.

This chapter proposes an item-level RFID-enabled store management system to help improve retail business. The system adopts an integral design approach to exploit RFID and the e-pedigree established for anti-counterfeiting and tracking of product items in a supply chain. Various modules, such as back-store inventory, smart shelves, interactive mirrors and fitting, and self-checkout services, can be subsequently implemented for retail operations and management. Features for anti-counterfeiting and individual customer marketing can also be incorporated to enhance brand image and customer experience. Moreover, intelligent algorithms may be integrated to mine useful information, such as the sales history of products and the shopping behaviour of customers from the data captured by the RFID devices to facilitate business decision-making and proactive individual marketing. As such, the efficiency of store operations and the overall retail business can be expected to improve substantially. The chapter presents the design approach of the proposed system and discusses some implementation issues, exemplified by two basic applications: (1) track-and-trace anti-counterfeiting to prevent injection of faked products into the back-store inventory and (2) smart product collocation to promote individual customer marketing and cross selling.

The importance of data as the fuel of artificial intelligence is self-evident. As the degree of informatization in various industries deepens, the amount of accumulated data continues to increase; however, data processing capability lags far behind the exponential growth of data volume. To gather accurate results, more and more data should be collected. However, the more data collected, the slower the processing and analyzing of that data. The emergence of deep learning solves the problem of how to process large amounts of data quickly and precisely. With the advancement of technology, the healthcare industry has achieved a promising level of needed data. Moreover, if deep learning can be used to aid disease diagnosis, patient data can be processed efficiently, useful information can be screened, valuable diagnostic rules can be mined, and disease diagnosis results can be better formulated and treated. It is foreseeable that deep learning has the potential to improve the effectiveness and the efficiency of healthcare and relevant industries.

Full textAbstract:
The study of the principles and approaches to the organization of self-educational activities in a university, the determination of its place in the process of professional training is one of the relevant topics of psychological, pedagogical and methodological research in the modern Russian scientific field. At the same time, such an aspect of the problem being studied as the development and justification of a complex set of factors contributing to the efficient organization of the self-educational activities of university students in the face of changing requirements of state standards and the development of modern professional education requires additional research. The article presents the results of a theoretical study of factors contributing to the efficiency of self-educational activities of university students. The first factor determining the efficiency of the self-educational activities of university students is the integrative nature of educational tasks. Students' self-educational activity, based on this approach, demonstrates efficiency when observing the following provisions: setting goals that involve an independent search for contradictions and identifying ways to solve them; development of a strategy of self-educational activity, taking into account the personality characteristics of the student and the level of his/her training; the goals of self-educational activities should be formulated in such a way that their achievement requires the student to use the full range of competencies acquired in the process of mastering individual academic disciplines: social, communicative and specialized; a clear structuring of the types and levels of integration in the curriculum of self-educational activities on the basis of gradually complicated problem-oriented tasks of the activity; providing the student with the right to choose the means and the algorithm for achieving the goal, taking into account his personal potential. The second factor contributing to the efficient flow of self-educational activities of university students is the formation of their motivation-value attitude to this type of activity through the development of motivation for professionalism, abilities and achievements. The authors consider the motivational component of the structure of self-educational activity as a key, giving rise to the entire learning process. The third factor that determines the efficient development of the skills of self-educational activities of university students is the use of telecommunication technologies, aimed at developing critical thinking and activating mental abilities. The authors believe that the described factors are basic and should be subjected to a more detailed analysis, which will become the basis for substantiating the set of pedagogical conditions for organizing this type of educational work.

The valve of the jetted self-priming set shut off when the pump self-priming was finished and the pump efficiency was increased. The design method, working mechanism and structure of the pump were introduced. The experiment results of the jet aerator of the pump, the self-shutoff of the reflowing valve and performance were obtained. The results showed that the self-priming performance of the pump was principal concern with the size of the jet aerator and the pump efficiency was increased as the reflowing valve automatically closing. The efficiency of the pump is higher by 5.3%∼8.9% and the time of the self-priming is shorter by 25∼73s and the average weight is lighter by 16% than the national standard, which indicates that comprehensive technical index is on the top of international level.

Full textAbstract:
Abstract Polymer coatings, especially epoxy and polyurethane paint systems, have been widely used to prevent corrosion of metallic components and structures. However, due to environmental and mechanical effects, the barrier efficiency of the coatings may be substantially compromised during transportation and service, as demonstrated by localized scratches, delamination, or stress-related microcracks. Application of a self-healing coating that can restore damages and recover its performance with minimal external intervention could prevent corrosion at the damaged coating. In this present work, the healing efficiency and long-term durability of Boronic Ester (BE) blended with Polyurethane (PU) as a self-healing system for top side coating of offshore platform structures was investigated. The BE was mixed at a ratio of 50:50 with PU resin and applied as a top layer on a PU coated steel plate with a thickness of approximately 300-350 μm. The healing efficiency, mechanical performance, and durability under simulated environmental conditions such as salt spray and UV were investigated according to the related ASTM standards. As a first step, the electrical impedance spectroscopy (EIS) and 3D profilemeter microscope were used to assess the healing ability of the scratched coating at room temperature and humidity level of 85 %. The mechanical performance of the self-healing coating layer was evaluated using a pull off adhesion test to investigate the compatibility of the self-healing system with the existing commercial PU topcoat system, while a long term 3000 hours salt spray and 4200 hours cyclic UV test were performed to evaluate the self-healing coating's durability in harsh conditions. Preliminary assessment using EIS and 3D profilemeter microscopes on the scratched PU/BE self-healing coating revealed significant healing efficiency of more than 80% for healing condition at ambient temperature and humidity level of 85%. The self-healing coating layer also demonstrated excellent adhesion efficiency, with adhesion greater than 300 psi suggesting good compatibility of the BE-PU layer with commercial PU coating. The salt spray and cyclic UV tests that were performed to determine the durability of the self-healing coating revealed that the 50BE/50PU layer remained intact and exhibited good healing performance with more than 80% efficiency even after exposure to harsh conditions. The findings from the study demonstrated that the BE/PU material has the potential to be used as a self-healing system for topside coating of offshore platforms structures, thereby lowering maintenance costs.

Full textAbstract:
Modern systems have become increasingly more complex, and their analysis becomes signicantly more complex. Many practical aspects of complex network tools have mainly been applied to critical infrastructure, in particular, to study power systems' resilience. Blackout prevention, system resilience, and restoration consider the ability of the system's self-healing. The self-healing strategies depend, basically, on the existence of extra lines to re-route energy.Some studies suggested that there is an optimum cost-benefit point when adding power lines redundancies to a system considering the systems' resilience. One method to solve this optimisation problem is the use of a metaheuristic algorithm. These algorithms combine exploration and exploitation on the search for a solution. In this paper, a Chu-Beasley genetic algorithm is used to search for the optimum cost-benefit level of redundancy in a system. Thesystem used is from the Repository of Distribution Systems (REDS), and the function used to evaluate the resilience considers an efficiency coecient so that the resilience by cost curve would have a maximum point. This experiment is executed as a topological analysis. The expected results were obtained using estimated curves from Monte-Carlo simulations for a wide range of combination of parameters. The results from three different parameters of efficiency coefficient were compared to the expected values obtained. The results show that there is a best cost-benefit level of redundancy when an efficiency level is determinate. Also, the GA used has excellent performance for finding this point.

Full textAbstract:
This paper presents an analysis of the role of decentralised institutions to understand the learning and challenges of the grass-roots-led pandemic response of Kerala. The study is based on interviews with experts and frontline workers to ensure the representation of all stakeholders dealing with the outbreak, from the state level to the household level, and a review of published government orders, health guidelines, and news articles. The outcome of the study shows that along with the decentralised system of governance, the strong grass-roots-level network of Accredited Social Health Activists (ASHA) workers, volunteer groups, and Kudumbashree members played a pivotal role in pandemic management in the state. The efficient functioning of local bodies in the state, experience gained from successive disasters, and the Nipah outbreak naturally aided grass-roots-level actions. The lessons others can draw from Kerala are the importance of public expenditure on health, investment for building social capital, and developing the local self-delivery system.

Full textAbstract:
This article demonstrates that mathematics in the system of higher education has outgrown the status of the general education subject and should become an integral part of the professional training of future bachelors, including economists, on the basis of intersubject connection with special subjects. Such aspects as the importance of improving the scientific and methodological support of mathematical training of students by means of digital technologies are revealed. It is specified that in order to implement the task of qualified training of students learning econometrics and economic and mathematical modeling, it is necessary to use digital technologies in two directions: for the organization of electronic educational space and in the process of solving applied problems at the junction of the branches of economics and mathematics. The advantages of using e-learning courses in the educational process are presented (such as providing individualization of the educational process in accordance with the needs, characteristics and capabilities of students; improving the quality and efficiency of the educational process; ensuring systematic monitoring of the educational quality). The unified structures of “Econometrics”, “Economic and mathematical modeling” based on the Moodle platform are the following ones. The article presents the results of the pedagogical experiment on the attitude of students to the use of e-learning course (ELC) in the educational process of Borys Grinchenko Kyiv University and Alfred Nobel University (Dnipro city). We found that the following metrics need improvement: availability of time-appropriate mathematical materials; individual approach in training; students’ self-expression and the development of their creativity in the e-learning process. The following opportunities are brought to light the possibilities of digital technologies for the construction and research of econometric models (based on the problem of dependence of the level of the Ukrainian population employment). Various stages of building and testing of the econometric model are characterized: identification of variables, specification of the model, parameterization and verification of the statistical significance of the obtained results.

Full textAbstract:
1. Abstract: Over the past 25 years, vine cacti of the genera Hylocereus and Selenicereus have been introduced into Israel and southern California as new exotic fruit crops. The importance of these crops lies in their high water use efficiency and horticultural potential as exotic fruit crops. Our collaboration focused on the cytological, molecular and evolutionary aspects of vine cacti polyploidization to confront the agricultural challenge of genetic improvement, ultimately to improve success of vine cacti as commercial fruit crop plants. More specifically, we worked on the: 1- Identification of the putative ancestor(s) of the tetraploid H. megalanthus; 2- Determination of the number of origins of H. megalanthus (single vs. multiple origins of polyploidy); 3- Cytogenetic analysis of BC1 and F1 hybrids; 4- Determination of important agricultural traits and the selection of superior hybrids for cultivation. The plant material used in this study comprised interspecific Hylocereus F1 and first backcross (BC1) hybrids, nine Hylocereus species (58 genotypes), nine Selenicereus species (14 genotypes), and four Epiphyllum genotypes. Two BC1 hexaploids (BC-023 and BC-031) were obtained, a high ploidy level that can be explained only by a fertilization event between one unreduced female gamete from the triploid hybrid and a balanced gamete from the pollen donor, the diploid H. monacanthus. These findings are scientific evidence that support the possibility that “hybridization followed by chromosome doubling” could also occur in nature. Cytomixis, the migration of chromatin between adjacent cells through connecting cytoplasmatic channels, was observed in vine cacti hybrids and may thus imply selective DNA elimination in response to the allopolyploidization process. Evidence from plastid and nrDNA internal transcribed spacers (ITS) sequences support the placement of H. megalanthus within a monophyletic Hylocereus group. Furthermore, both plastid and ITS datasets are most consistent with a conclusion that this tetraploid species is an autopolyploid, despite observations that the species appears to be morphologically intermediate between Hylocereus and Selenicereus. Although the possibility of very narrow allopolyploidly (i.e., derivation from parents that are barely diverged from each other such as closely related species in the same genus) cannot be ruled out entirely based on our data (in part due to the unavailability of Hylocereus species considered to be morphologically the closest relatives of H. megalanthus), the possibility of H. megalanthus representing an intergeneric cross (i.e., Hylocereus × Selenicereus) seems extremely unlikely. Interestingly, the process of homogenization of ITS sequences (concerted evolution) is either incomplete or lacking in both Hylocereus and Selenicereus, and the inclusion of several artificial hybrids in the molecular study revealed the potential for biparental plastid inheritance in Hylocereus. The most important agricultural implication of this research project was the information collected for F1 and BC1 hybrids. Specifically, this project concluded with the selection of four superior hybrids in terms of fruit quality and potential yields under extreme high temperatures. These selected hybrids are self-compatible, avoiding the need for hand cross pollination to set fruits, thus reducing manpower costs. We recently offered these hybrids to growers in Israel for prioritized rapid evaluation and characterization.

Full textAbstract:
Historically, the aversive response of humans and other mammals to bitter-taste substances has been useful for survival, since many toxic constituents taste bitter. Today, the range of foods available is more diverse. Many bitter foods are not only safe for consumption but contain bitter constituents that provide nutritional benefits. Despite this, these foods are often eliminated from our current diets because of their unacceptable bitterness. Extensive technology has been developed to remove or mask bitterness in foods, but a lack of understanding of the mechanisms of bitterness perception at the taste receptor level has prevented the development of inhibitors or efficient methods for reducing bitterness. In our original application we proposed to: (a) investigate the time course and effect of selected bitter tastants relevant to agricultural products on the formation of intracellular signal molecules (cAMP, IP3, Ca2+) in intact taste cells, in model cells and in membranes derived therefrom; (b) study the effect of specific bitter taste inhibitors on messenger formation and identify G-proteins that may be involved in tastant-induced bitter sensation; (c) investigate interactions and self-aggregation of bitter tastants within membranes; (d) study human sensory responses over time to these bitter-taste stimuli and inhibitors in order to validate the biochemical data. Quench-flow module (QFM) and fast pipetting system (FPS) allowed us to monitor fast release of the aforementioned signal molecules (cGMP, as a putative initial signal was substituted for Ca2+ ions) - using taste membranes and intact taste cells in a time range below 500 ms (real time of taste sensation) - in response to bitter-taste stimulation. Limonin (citrus) and catechin (wine) were found to reduce cellular cAMP and increase IP3 contents. Naringin (citrus) stimulated an IP3 increase whereas the cheese-derived bitter peptide cyclo(leu-Trp) reduced IP3 but significantly increased cAMP levels. Thus, specific transduction pathways were identified, the results support the notion of multiple transduction pathways for bitter taste and cross-talk between a few of those transduction pathways. Furthermore, amphipathic tastants permeate rapidly (within seconds) into liposomes and taste cells suggesting their availability for direct activation of signal transduction components by means of receptor-independent mechanisms within the time course of taste sensation. The activation of pigment movement and transduction pathways in frog melanophores by these tastants supports such mechanisms. Some bitter tastants, due to their amphipathic properties, permeated (or interacted with) into a bitter tastant inhibitor (specific phospholipid mixture) which apparently forms micelles. Thus, a mechanism via which this bitter taste inhibitor acts is proposed. Human sensory evaluation experiments humans performed according to their 6-n-propyl thiouracil (PROP) status (non-tasters, tasters, super-tasters), indicated differential perception of bitterness threshold and intensity of these bitter compounds by different individuals independent of PROP status. This suggests that natural products containing bitter compounds (e.g., naringin and limonin in citrus), are perceived very differently, and are in line with multiple transduction pathways suggested in the biochemical experiments. This project provides the first comprehensive effort to explore the molecular basis of bitter taste at the taste-cell level induced by economically important and agriculturally relevant food products. The findings, proposing a mechanism for bitter-taste inhibition by a bitter taste inhibitor (made up of food components) pave the way for the development of new, and perhaps more potent bitter-taste inhibitors which may eventually become economically relevant.

Full textAbstract:
As widely argued [HG97; Sat96], transitive roles play an important role in the adequate representation of aggregated objects: they allow these objects to be described by referring to their parts without specifying a level of decomposition. In [HG97], the Description Logic (DL) ALCHR+ is presented, which extends ALC with transitive roles and a role hierarchy. It is argued in [Sat98] that ALCHR+ is well-suited to the representation of aggregated objects in applications that require various part-whole relations to be distinguished, some of which are transitive. However, ALCHR+ allows neither the description of parts by means of the whole to which they belong, or vice versa. To overcome this limitation, we present the DL SHI which allows the use of, for example, has part as well as is part of. To achieve this, ALCHR+ was extended with inverse roles. It could be argued that, instead of defining yet another DL, one could make use of the results presented in [DL96] and use ALC extended with role expressions which include transitive closure and inverse operators. The reason for not proceeding like this is the fact that transitive roles can be implemented more efficiently than the transitive closure of roles (see [HG97]), although they lead to the same complexity class (ExpTime-hard) when added, together with role hierarchies, to ALC. Furthermore, it is still an open question whether the transitive closure of roles together with inverse roles necessitates the use of the cut rule [DM98], and this rule leads to an algorithm with very bad behaviour. We will present an algorithm for SHI without such a rule. Furthermore, we enrich the language with functional restrictions and, finally, with qualifying number restrictions. We give sound and complete decision proceduresfor the resulting logics that are derived from the initial algorithm for SHI. The structure of this report is as follows: In Section 2, we introduce the DL SI and present a tableaux algorithm for satisfiability (and subsumption) of SI-concepts—in another report [HST98] we prove that this algorithm can be refined to run in polynomial space. In Section 3 we add role hierarchies to SI and show how the algorithm can be modified to handle this extension appropriately. Please note that this logic, namely SHI, allows for the internalisation of general concept inclusion axioms, one of the most general form of terminological axioms. In Section 4 we augment SHI with functional restrictions and, using the so-called pairwise-blocking technique, the algorithm can be adapted to this extension as well. Finally, in Section 5, we show that standard techniques for handling qualifying number restrictions [HB91;BBH96] together with the techniques described in previous sections can be used to decide satisfiability and subsumption for SHIQ, namely ALC extended with transitive and inverse roles, role hierarchies, and qualifying number restrictions. Although Section 5 heavily depends on the previous sections, we have made it self-contained, i.e. it contains all necessary definitions and proofs from scratch, for a better readability. Building on the previous sections, Section 6 presents an algorithm that decides the satisfiability of SHIQ-ABoxes.
