В работе рассматривается метод оценки маршрута судна с точки зрения безопасности и оптимальности. Оценка выполняется за счёт вычисления характеристических коэффициентов, которые описывают свойства маршрута, важные для оценки этих качеств. Также в работе даётся описание метода прогнозирования дальнейшего маршрута судна на основе предписанного маршрута рейса и информации о существующем отклонении фактического маршрута от предписанного. На основе прогнозирования дальнейшего маршрута, и с использованием характеристических коэффициентов, становится возможным анализ долгосрочного влияния отклонения фактического маршрута от предписанного. Маршрут рассматривается как динамическая характеристика судна, эволюционирующая с течением времени. Обсуждаются особенности развития маршрута судна при стремлении к стабильному либо катастрофичному состоянию с позиций современной теории катастроф. Геометрическая интерпретация эволюционной динамики предусматривает использование когнитивных образов. В работе приводится анализ произошедшей аварии круизного судна Costa Concordia с использованием предложенного метода с целью исследования влияния изменения маршрута на безопасность рейса. Выполняется сравнение предписанного маршрута с фактическим.The paper presents a method to analyze a ships route in terms of safety and optimality. The route is examined using the characteristic coefficients that represent routes properties essential for assessment of these aspects. The paper also presents a method to estimate the future route based on the prescribed route and the existing discrepancy between the actual route and the prescribed one. With such estimation technique and using the characteristic coefficients it is possible to determine the long-term effects of the discrepancy. The route is considered as a dynamic characteristic of the ship, evolving over time. Peculiarities of the development of the ships route when striving for a stable or catastrophic state from the standpoint of the modern catastrophe theory are discussed. A geometric interpretation of evolutionary dynamics involves the use of cognitive images. As an example, the paper provides analysis of the Costa Concordias accident using the described method in order to determine the effects of the route discrepancy. A comparison is made of the prescribed route with the actual one that the crew planned to move.

The agritourism activity can be a characteristic reality of the present, considering rural area’s sustainability, being at the same time a business reality for rural entrepreneurs and a “must have” for rural communities that have tourism potential. It is a form of tourism, through which the tourist can receive a qualitative product at a reasonable price, but also a field that can ensure sustainable development over time, being at the same time environmentally friendly. The purpose of this scientific paper is to identify the aspects that make agritourism “a possible business reality of the moment”, for Romanian rural area’s sustainability. We take into account the following areas: Bran-Moieciu area—considered “the oldest” in terms of agritourism experience, and Apuseni Mountains area, with a great inclination and potential for this activity. The study conducted for these two areas is focused on several aspects: the degree of involvement in agritourism activities, considering the number of years and managerial experience, the analysis of the types of activities/experiences offered by agritourism structures, the identification of the main reasons/motivations for the orientation towards agritourism and the manner in which this field is perceived. Aspects related to the marketing-finance part of the agritourism business are also taken into account: customers, distribution channels, financial sources, shortcomings observed by agritourism business owners and possible action directions so as to improve the activity/agritourism product. Agritourism may be “a possible business reality of the moment” for the studied areas and not only, but in the future, the entrepreneur/farmer must be constantly updated because of the changing situations that appear on the market, be able to make sustainable decisions for his/her own business, which in the future will ensure its viability and obviously its long-term profitability and development, and in the same time rural area’s sustainability.

Nine years after liming a sandy loam orchard soil to pH 6.0 with calcium hydroxide or dolomitic lime, pH and extractable Ca and Mg were still higher where limed than where unlimed. However, pH had decreased below 5.0 in the limed and N-fertilized plots. Delicious (Malus domestica Borkh.) apple tree nutrition benefited from the two soil amendments. Leaf Mg was increased by dolomite. Leaf Ca was increased by calcium hydroxide. Leaf Mn, although highest in unlimed soils, increased over time for both limed and unlimed soil.

Studies analysing the positive role of pragmatic instruction in formal settings have increased over the last decades. Within this area of interventional pragmatics, some studies have particularly examined whether the effectiveness of the instruction implemented is sustained over time. In order to shed more light on the long-term effects of instruction, this research investigates English as a Foreign Language learners’ use of complaining formulas not only after immediately receiving instruction, but also two months later. Results show that learners keep using a variety of appropriate complaining formulas two months after having participated in the instructional period. These findings are discussed and directions for future research suggested.

The purpose of this chapter is to investigate the potential long-term effects of contemporary globalization on the Chinese economy and innovation in an era of global hypercompetition. Globalization today is basically accepted as the process that removes geographical boundaries and enables the economic integration and interdependence of national economies into the international economy through trade, foreign direct investment, migration, and capital flows. Since productivity remains the critical determinant of long-term national growth and prosperity, the effects of today's globalism on productivity demands the need for business organizations in particular to sustain a competitive advantage and to remain profitable over time. Based on an integrative literature review, this chapter explores why China must continue to develop its innovation capabilities as well as to provide opportunities for foreign businesses over the long-term via responsible economic development that also benefits the nation's domestic population.

The conclusion provides some final observations about the longitudinal research itself and its short- and long-term effects on the women involved. It briefly touches on the few areas of the sport marriage that have seen improvement in the past few decades, discusses the conscious decisions the women make to continue normalizing the career-dominated marriage, and reports on how the marriages fared over time. It also describes the women’s personal empowerment as a result of their participation in the research. Finally, it summarizes the advice and suggested keys to a successful sport marriage that the wives in both studies offered, based on their lived experience. This overview essentially describes how and why the wife of a male professional athlete must adapt to realities if she wants her marriage to survive her husband’s career and retirement.

AbstractBreast cancer is one of the most common malignancies which appear during pregnancy. Since women are increasingly not giving birth until they are at a more advanced age, it can be assumed that the incidence of pregnancy-related breast cancers will continue to increase in the future. Because of pregnancy-induced changes and conservative diagnosis, these carcinomas are frequently not detected until they are at an advanced stage and thus generally require systemic adjuvant therapy. The available data on optimal chemotherapeutic management are limited. Particularly for the use of the target agent trastuzumab which could crucially contribute to improving the prognosis in the therapy of HER2-overexpressing breast cancer in non-pregnant women, there is a lack of definitive information regarding the profile of action and safety in pregnancy as well as with regard to any long-term effects on the child. Thirty-eight pregnancies on trastuzumab for the treatment of breast cancer were able to be analysed in the literature currently available. Information can be gained from this and conclusions can be drawn which can individualise and decisively improve therapeutic options in the future for the pregnant breast cancer patient.

In this commentary, we discuss some possible effects of the COVID-19 pandemic in both established and newer democracies. We expect that the pandemic will not have grave long-term effects on established democracies. We assess the future of democracy after COVID-19 in terms of immediate effects on current democratic leaders, and speculate on the long-term effects on support for democratic institutions and principles. We also discuss possible implications of the COVID-19 pandemic on the global trends in democratic backsliding. We predict that, in the short term, the repercussions of the pandemic can aggravate the situation in countries that are already experiencing democratic erosion. However, the long term economic effects of the pandemic may be more detrimental to non-democratic governance.

Abstract Background The global financial crisis emerging in 2008 struck Greece especially hard, whereas Scandinavian countries were less affected. This has created a unique opportunity to study the long-term effect of community stress on populations. Increasing frequencies of mental health issues and poorer perceived health among the Greek population have been reported. The physiological marker of long-term stress, cortisol in hair, is applied in this study together with measures of perceived health and stress, depression and anxiety. Our aim was to study self-reported and physiological stress, perceived health, including mental health, in the general population of Greece compared to Scandinavia, in order to assess long-term effects of the economic crisis on these parameters. Methods A cross-sectional comparative study of adult (18–65 years) Primary Health Care visitors from semi-rural areas in Greece (n = 84) and Scandinavia (n = 140). Data collection was performed in 2012, and encompassed a questionnaire with a variety of health and stress indicators as well as hair samples for analyzes of cortisol levels. Results The Greek sample reported significantly poorer overall health (p < 0.0001) than the Scandinavians and a significantly higher perceived stress (p < 0.0001). The Greeks were also less hopeful of the future (p < 0.0001), and to a larger extent fulfilled the HAD criteria for depression (p < 0.0001) and anxiety (p = 0.002). The strongest predictors explaining ill health in logistic regressions were being Greek (p = 0.001) and feeling hopeless about the future p = 0.001, OR = 6.00 (CI 2.10–14.88). Strong predictors in logistic regressions for high perceived stress were anxiety: high (p < 0.0001) and medium (p = 0.0001), as well as medium depression (p = 0.02). Conclusions Greek adult Primary Health Care visitors perceived their health more negatively than the Scandinavians, including a higher presence of depression, anxiety, and a lower hope for the future. The Greeks also reported higher perceived stress, but this was not reflected in higher cortisol levels. The findings presented here, identify possible adverse long-term effects of the economic crisis in the examined Greek population that are not seen in the Scandinavian cohort. These differences may also be interpreted against the background of socio-cultural differences in the northern and south-eastern corners of Europe.
