In response to the pandemic of COVID-19 and in lack of pharmaceutical solutions, many countries have introduced social and physical distancing regulations to contain the transmission of the virus. These measures are effective insofar as they are able to quickly change people's habits. This is achieved by changing the monetary incentives of rule violators but also by shifting people's perception regarding the appropriateness of socialization. We studied the effect of introducing, and then lifting, distancing regulations on the perceived norm regarding social encounters. We conducted an online incentivized experiment in France where we elicited the same participants' perceived norm and social distancing behavior every week for three months. We found that people shifted behavior and norm perception as soon as the government introduced or removed distancing measures. This effect was fast acting and long lasting. This is informative for future interventions, especially in light of a possible COVID-19 recurrence.

On the one hand, recent advances in satellite imagery and remote sensing allow one to easily follow in near-real time the crop conditions all around the world. On the other hand, it has been shown that governmental agricultural reports contain useful news for the commodities market, whose participants react to this valuable information. In this paper, we investigate wether one can forecast some of the newsworthy information contained in the USDA reports through satellite data. We focus on the corn futures market over the period 2000-2016. We first check the well-documented presence of market reactions to the release of the monthly WASDE reports through statistical tests. Then we investigate the informational value of early yield estimates published in these governmental reports. Finally, we propose an econometric model based on MODIS NDVI time series to forecast this valuable information. Results show that market rationally reacts to the NASS early yield forecasts. Moreover, the modeled NDVI-based information is signicantly correlated with the market reactions. To conclude, we propose some ways of improvement to be considered for a practical implementation.

This article explores the main determinants of the hazard of recidivism among ex-prisoners. We use a nationally-representative sample of prisoners released in 1996-1997 in France, drawn from a 5-year follow-up survey run by the French correctional administration. We estimate semiparametric duration models which deal with violations of the proportional hazards hypothesis. Our results confirm the importance of gender, age, nationality, access to employment and prior convictions on recidivism within five years after release from prison. We also find significant differences in hazards of recidivism by type of initial offense, penal status at entry, and type of release (early release under parole, etc.), while controlling for prison fixed effects. Finally, our study casts doubt on the influence of certain variables (marital status at entry, education, homelessness) and on the effectiveness of semi-liberté as a way to prevent recidivism.

This thesis explores auditor civil liability towards the company and third parties in Saudi Arabia and selected common law countries. In Chapter One, the researcher outlines the methodology adopted to conduct this study using descriptive analysis as well as both doctrinal and comparative approaches. Chapter Two will present the nature of auditor civil liability towards companies and third parties in Saudi Arabia based on Islamic law of tort and modern legislation. Chapter Two also argues that as of 2020 the Saudi judiciary has struggled to cope with issues raised in common law countries due to the complexity of existing Shariah principles and regulation, the lack of understanding among judges and legal practitioners of shareholders' right to be indemnified that may lead to a weak litigation culture. However, the Chapter identifies a few legal provisions and established Islamic principles that would entitle shareholders to be indemnified on behalf of their corporation through personal and class actions if the company refuses to file the suit for their benefit. Despite the fact that there is no specific article showing how a court can determine the proper damages suffered by shareholders, the researcher has designed mathematical formulae to assist Saudi judges in this respect considering Saudi legal regulations and Islamic principles. A better understanding on how Islamic principles and legal provisions operate, will hopefully assist and benefit judges, practitioners and litigants. This thesis argues in Chapters Three and Four that common law principles with respect to auditors' civil liability to third parties, and more particularly to shareholders, are not satisfactory from the Saudi perspective. Chapter Three is focused on theories of auditor liability towards third parties, with a focus on the United States of America (US), perhaps the first country with a clear precedent in this respect. Chapter Four then looks at England where two contrasting cases with respect to the liability of the auditor, and some other related cases, are examined. Chapter Four also investigates auditors' civil liability towards third parties in other common law jurisdictions that follow the approaches adopted in the US or in England either completely or partially. Since, in practice, the availability or non-availability of insurance to indemnify auditors against liability to shareholders and others has a significant impact on the topic under review in this thesis, Chapter Five then goes on to discuss the nature of Takaful - "an Islamic form of insurance" - and compares it to from conventional (western) insurance, and as well as the challenges that the Islamic model faces in Muslim majority and Muslim minority jurisdictions. Chapter Six develops that discussion by examining conventional liability products and exposing their limitations in providing appropriate protection and indemnification for those insured. Chapter Seven, draws together the key arguments, reasons and principles developed by common-law judges in the context of auditor liability, and explores a recent case from Saudi Arabia. The chapter also develops the discussion of the potential for insurance to extend to auditor liability by comparing and contrasting actual and existing applications of Takaful and conventional insurance in the area of professional liability. Chapter Eight addresses the research questions posed in Chapter One and concludes with final remarks and observations on the implications of the research.
Предметом настоящей статьи является миграция из России. Тема исследования посвящена современным особенностям и новым формам эмиграции. Целью работы является выявление новых закономерностей, определяющих эмиграцию из страны. В статье эмиграция рассматривается в широком смысле, включая в себя, помимо классической эмиграции (то есть выезд на постоянное место жительства в другую страну), различные категории возвратной миграции (трудовая миграция, «челноки», сезонная миграция, эпизодическая миграция, экономический туризм, бизнес-миграция, выезд на учебу и др.). С появлением новых форм и категорий миграции возникла необходимость в уточнении понятийного аппарата. Анализ построен на базе широкого исторического экскурса в отношении эмиграции, которая была характерным явлением для России в течение последних трех веков. Статья базируется на таких экономических теориях, как теория человеческого капитала, новая экономическая теория миграции, экономическая теория миграции Тодаро и др. В статье используются различные методы, включая исторические аналогии, статистико-математические подходы, социологические и эконометрические модели. В статье проанализированы закономерности современной эмиграции из России. Также затрагиваются отдельные аспекты правового регулирования миграционных процессов с акцентом на эмигрантов, включая потенциальных эмигрантов. В заключении статьи отмечается необходимость государственного управления процессами эмиграции. Речь идет не столько об улучшении статистического учета этой группы мигрантов, сколько о конкретных государственных мерах, направленных не на запрещение, о вредности которого писал еще М.В. Ломоносов, а на поддержку государством этих категорий мигрантов с целью недопущения безвозвратной миграции. Результаты данного исследования могут быть использованы в процессе совершенствования миграционной политики, проводимой, в частности, Федеральной миграционной службой России. ; The subject-matter of this article is migration from Russia. The study deals with current aspects and new forms of emigration. The goal of this paper is to identify new patterns determining the emigration from Russia. The article views the emigration in a broad sense, including, in addition to classic emigration (i.e. leaving the home country for permanent residence in another country), various categories of return migration (labor migration, shuttle traders, seasonal migration, episodic migration, economic tourism, business migration, education abroad, etc.). With the emergence of these new forms and categories, there is a need to clarify the migration concepts. This analysis is built on a broad historical perspective on emigration, which has been a typical phenomenon for Russia over the last three centuries. The article is based on such economic theories, as the human capital theory, new economic theory of migration, Todaro's economic theory of migration and other. In this article, a variety of methods are used, including historical analogy, statistical and mathematical approaches, sociological and econometric models. The article analyzes the patterns of modern emigration from Russia. It also considers certain aspects in the legal regulation of migration processes, with a focus on emigrants, including potential emigrants. In conclusion, the article notes the need for the state control of emigration processes. This means not so much the improvement of statistical records for this group of migrants, but rather specific government measures aimed at providing the state support to these categories of migrants in order to prevent the nonreturn migration. In other words, it is not aimed at banning the emigration (a measure, the adverse effects of which were noted as long ago as by Mikhail Lomonosov), but at providing the state support to these categories of migrants in order to prevent the non-return migration. The findings of this research can be used in improving the migration policy implemented, in particular, by the Federal Migration Service of Russia.
Методология анализа риска здоровью населения на современном этапе развития российского общества востребована на всех уровнях государственного управления. В сопряжении с методами математического моделирования, пространственно-временного анализа и экономическими инструментами оценка риска при анализе ситуации позволяет определять уровень безопасности населения, работающих и потребителей продукции, выделять приоритетные источники и факторы угроз как точки приложения усилий. На стадии планирования оценка риска является основой установления наиболее эффективных мер по минимизации угроз и опасностей. На стадии реализации планов действий методология дает возможность оценить эффективность мероприятий; на стадии контроля и надзора выделять приоритеты для концентрации усилий на объектах наибольшего риска для здоровья граждан. Оценки риска, в том числе с элементами эволюционного моделирования, включают в систему государственного гигиенического нормирования, в формирование доказательной базы вреда здоровью, в организацию контрольно-надзорной деятельности. Это позволяет гармонизировать отечественную нормативно-правовую базу с мировыми законодательными требованиями и в конечном итоге повышает доверие к российским данным о безопасности среды обитания, товаров и услуг. Актуальным представляется дальнейшее закрепление правоприменения методологии анализа риска здоровью в сфере обеспечения санитарно-эпидемиологического благополучия населения и охраны здоровья работающих; развитие информационно-аналитической базы в части установления моделей зависимостей экспозиция-ответ для различных типов и уровней экспозиции и контингентов риска; повышения точности оценок экспозиции; совершенствование экономических аспектов анализа риска здоровью и прогнозирование мер, направленных на снижение потерь, связанных с негативным воздействием разнородных факторов на здоровье граждан. ; The methodology of the analysis of health risk at the present stage of development of Russian society is in-demand at all levels of government management. In conjunction with the methods of mathematical modeling, spatial-temporal analysis and economic tools the risk assessment in the analysis of the situation makes it possible to determine the level of safety of the population, workers and consumers, to select prior resources, and threat factors as a point for exertion efforts. At the planning stage risk assessment is a basis for the establishment of most effective measures for the minimization of hazard and dangers. At the realization stage the methodology allows to estimate the efficiency of measures; at the control and supervision phase it permits to select out priorities for the concentration of efforts on the objects of maximal health risk for population. Risk assessments, including the elements of evolutionary modeling, are incorporated in the system of state hygienic regulation, the formation of evidence base of harm to health, the organization of control and supervisory activities. This allows you to harmonize the domestic legal framework with international legal requirements and ultimately enhances the credibility of the Russian data on the safety of the environment, products and services. There is seemed to be actual the further assignment of enforcement of methodology of health risk analysis in the field of assurance of sanitary and epidemiological well-being and health of employers; the development of informational and analytical base in the part of the establishment of models of dependencies "exposure-response" for different types and levels of exposure and risk contingents; the accuracy enhancement of estimations of exposure; improvement of the economic aspects of health risk analysis and forecasting of measures aimed at mitigation of the losses associated with the negative impact of manifold factors on the health of citizens.
В данной статье проанализировано социально-экономическое состояние России в настоящее время с учетом воздействия негативных факторов - введение санкций США и Евросоюзом в отношении России и принятия правительством антикризисных мер, направленных на поддержание социальной стабильности. Дана оценка Федеральному бюджету на 2015 г. и на плановый период 2016 и 2017 гг. как одному из основных регуляторов обеспечения экономической безопасности, предусматривающему утверждение основных характеристик на ближайшие три года, с учетом присоединения Крыма, бюджетных правил, позволяющих снизить зависимость исполнения расходных обязательств от изменения мировых цен на энергоресурсы, возможных последствий западных санкций и налогового маневра. Выявлены слабые места действующих на сегодняшний день пороговых значений показателей социально-экономического развития нашего государства. Обусловлена актуальность исследования по определению пороговых значений математическими методами на основе имеющихся официальных статистических наблюдений за последние 15-20 лет в условиях стабильно развивающейся социально-экономической жизни в стране. Проведен мониторинг фактических показателей индикаторов социально-экономического развития в социальной сфере за последние полтора десятилетия на примере среднемесячной начисленной заработной платы, среднедушевых денежных доходов населения, численности населения, коэффициента рождаемости в расчете на одну женщину, индекса потребительских цен. Построены линии тренда, подобраны соответствующие модели уравнений с учетом полученных значений средней ошибки апроксимации, рассчитаны прогнозные показатели до 2018 г. На основе полученных результатов предложена классификация угроз по степени их реального воздействия и оказанных последствий на экономическую безопасность в социальной сфере. ; In this article the author analyzed the social and economic condition of Russia now taking into account influence of negative factors imposition of sanctions of the USA and the European Union concerning Russia and acceptance by the government of the anti-recessionary measures directed on maintenance of social stability. The author gave the assessment to the Federal budget for 2015 and on planning period 2016 and 2017 as to one of the main regulators of providing economic security providing the approval of the main characteristics for the next three years taking into account accession of the Crimea, the budgetary rules allowing to reduce dependence of execution of account obligations on change of the world prices for energy resources, possible consequences of the western sanctions and tax maneuver. The article revealed weak points of the threshold values of indicators of social and economic development of our state operating today. The author determined relevance of research on determination of threshold values by mathematical methods on the basis of the available official statistical supervision for the last 15-20 years in the conditions of steadily developing social and economic life in the country. The author also carried out monitoring of the actual indicators of indicators of social and economic development in the social sphere for the last one and a half decades on the example of the average monthly added salary, the average per capita monetary income of the population, population size, birth rate coefficient counting on one woman, a consumer price index. In the article the author built lines of a trend, the corresponding models of the equations taking into account the received values of an average error of approximation and calculated expected indicators till 2018. The author offered classification of threats by extent of their real influence and the rendered consequences on economic security in the social sphere on the basis of the received results.
В современной России из-за нестабильных политических отношений с соседними государствами реализуется крупная программа проектирования и строительства транснациональных магистральных трубопроводных систем. Обеспечение грузовой устойчивости комплекта машин трубоукладочной колонны является основной проблемой, с которой сталкиваются во время укладки трубопровода в траншею. Причинами потери краном-трубоукладчиком грузовой устойчивости являются: 1. малоопытные машинисты крана-трубоукладчика, которые, реагируя на частичную потерю грузовой устойчивости, чрезмерно разгружают свою машину, перегружая тем самым ее соседние; 2. неровности микрорельефа, по которому двигаются краны-трубоукладчики. Из всего сказанного можно сделать вывод о необходимости создания устройства управления трубоукладочной колонной, которое бы решило следующие проблемы: 1. предотвращение аварийных ситуаций в рабочем процессе трубоукладочной колонны; 2. облегчение труда машинистов крана-трубоукладчика; 3. уменьшение автоколебаний трубопровода; 4. обеспечение равной загруженности всех кранов-трубоукладчиков, входящих в трубоукладочную колонну. Цель работы: повышение безопасности рабочего процесса трубоукладочной колонны, предотвращение аварийной ситуации. Методы исследования основываются на анализе и синтезе полученных результатов исследования; теоретические исследования базируются на математическом анализе, методах имитационного моделирования; экспериментальные исследования основаны на использовании теории планирования эксперимента и методах статистической обработки данных. Результаты: На примере трубоукладочной колонны изучены особенности рабочего процесса комплекта грузоподъемных машин с целью обеспечения безопасности выполняемых работ. Предложена теоретическая концепция, основанная на компенсации возникающих во время рабочего процесса динамических воздействий на грузоподъемную технику. Разработано устройство управления комплектом машин, обеспечивающее грузовую устойчивость трубоукладочной колонны. Предложена перспективная модель крана-трубоукладчика с устройством стабилизации грузового момента.A large-scale program of designing and constructing transnational pipeline systems is implemented in modern Russia because of its unstable political relations with neighboring states. The main problem when laying pipeline in a trench is ensuring cargo stability of a set of pipe-laying column cars. There are some reasons of loosing cargo stability by a pipe layer crane: 1. inexperienced drivers. They react to partial loss of cargo stability and unload excessively the car, overloading the next pipe-layer crane; 2. roughness of a microrelief. The conclusion can be drawn on designing a control unit for a pipe-laying column to solve the following problems: 1. prevention of emergencies in pipe-laying column operation; 2. simplification of a pipe-layer crane driver work; 3. reduction of pipeline self-oscillations; 4. equal load of all pipe layer cranes of a pipe-laying column. The main aim of the study is to increase safety of a pipe-laying column operation; to prevent emergency. The methods used in the study are based on the analysis and synthesis of the results received in the research; theoretical researches are based on mathematical analysis, methods of imitating modeling; pilot studies are based on use of the experiment planning theory and the methods of statistical data processing. The results: Based on the example of a pipe-laying column the authors have studied the features of a load-lifting cars set operation to ensure safety of the works; have proposed the theoretical concept based on compensation of dynamic impacts on load-lifting equipment arising at operation; have designed the cars set control unit, providing cargo stability of a pipe-laying column. The paper introduces the perspective model of the pipe layer crane with the cargo moment stabilization device.
