Abstract We incorporate unawareness into the delegation problem between a financial expert and an investor, and study their pre-delegation communication. The expert has superior awareness of the possible states of the world, and decides whether to reveal some of them to the investor. We find that the expert reveals all the possible states to the investor if the investor is initially aware of a large set of possible states, but reveals partially or nothing otherwise. An investor with a higher degree of unawareness tends to delegate a larger set of projects to the expert, giving rise to a higher incentive for the expert to keep her unaware.

<p><span lang="EN-US">The rapid development of information technology has made security become extremely. Apart from easy access, there are also threats to vulnerabilities, with the number of cyber-attacks in 2019 showed a total of 1,494,281 around the world issued by the </span><span lang="EN-US">national cyber and crypto agency (BSSN) honeynet project. Thus, vulnerability analysis should be conducted to prepare worst case scenario by anticipating with proper strategy for responding the attacks. Actually, vulnerability is a system or design weakness that is used when an intruder executes commands, accesses unauthorized data, and carries out denial of service attacks. The study was performed using the AlienVault software as the vulnerability assessment. The results were analysed by the formula of risk estimation equal to the number of vulnerability found related to the threat. Meanwhile, threat is obtained from analysis of sample walkthroughs, as a reference for frequent exploitation. The risk estimation result indicate the 73 (seventy three) for the highest score of 5 (five) type risks identified while later on, it is used for re-analyzing based on the spoofing, tampering, repudiation, information disclosure, denial of service, and elevation of prvilege (STRIDE) framework that indicated the network function does not accommodate the existing types of risk namely spoofing.</span></p>

Professor Zdzisław Żygulski Jr. (1921–2015) was one of the most prominent Polish art historians of the second half of the 20th century. He treated the history of art as a broadly understood science of mankind and his artistic achievements. His name was recognised in global research on antique weapons, and among experts on Rembrandt and Leonardo da Vinci. He studied museums and Oriental art. He wrote 35 books, about 200 articles, and numerous essays on art; he wrote for the daily press about his artistic journeys through Europe, Japan and the United States. He illustrated his publications with his own photographs, and had a large set of slides. Żygulski created many exhibitions both at home and abroad presenting Polish art in which armour and oriental elements played an important role. He spent his youth in Lvov, and was expatriated to Cracow in 1945 together with his wife, the pottery artist and painter Eva Voelpel. He studied English philology and history of art at the Jagiellonian University (UJ), and was a student under Adam Bochnak and Vojeslav Molè. He was linked to the Czartoryski Museum in Cracow for his whole life; he worked there from 1949 until 2010, for the great majority of time as curator of the Arms and Armour Section. He devoted his whole life to the world of this museum, and wrote about its history and collections. Together with Prof. Zbigniew Bocheński, he set up the Association of Lovers of Old Armour and Flags, over which he presided from 1972 to 1998. He set up the Polish school of the study of militaria. He was a renowned and charismatic member of the circle of international researchers and lovers of militaria. He wrote the key texts in this field: Broń w dawnej Polsce na tle uzbrojenia Europy i Bliskiego Wschodu [Weapons in old Poland compared to armaments in Europe and the Near East], Stara broń w polskich zbiorach [Old weapons in Polish armouries], Polski mundur wojskowy [Polish military uniforms] (together with H. Wielecki). He was an outstanding researcher on Oriental art to which he dedicated several books: Sztuka turecka [Turkish art], Sztuka perska [Persian art], Sztuka mauretańska i jej echa w Polsce [Moorish art and its echoes in Poland]. Prof. Zdzisław Żygulski Jr. was a prominent educator who enjoyed great respect. He taught costume design and the history of art and interiors at the Academy of Fine Arts in Cracow, as well as Mediterranean culture at the Mediterranean Studies Department and at the Postgraduate Museum Studies at the UJ. His lectures attracted crowds of students, for whose needs he wrote a book Muzea na świecie. Wstęp do muzealnictwa [Museums in the world. Introduction to museum studies]. He also lectured at the Florence Academy of Art and at the New York University. He was active in numerous Polish scientific organisations such as PAU, PAN and SHS, and in international associations such as ICOMAM and ICOM. He represented Polish art history at general ICOM congresses many times. He was also active on diverse museum councils all over Poland.

Frustration of purpose remains one of the most ill-defined concepts in the English law of contracts. The same problem has also recently attracted the attention of the French legislature in its modernization of the Code Civil. The French reform entitles courts with broad powers to adjust the contract when unforeseen contingencies have made the bargain unduly costly. This article argues that the introduction of an economically inspired adjustment rule in English contract law should be re-considered to maintain its current superior commercial position. If implemented, then the ‘ex ante division of surplus’ should be the governing principle in adjusting contract price, because such a remedy will not affect the agreed-upon division of the surplus. Moreover, this paper suggests that the recent French reform is indeed a long-awaited step toward a more effective regulation of the notorious ‘unforeseen contingencies’ phenomena, but also suggests that further improvements might be needed. Furthermore, it offers a set of arguments suggesting that the English law in its current form might still be the preferred option in the world of international business transactions. The international commercial attractiveness of English contract law, although being challenged by the new French Civil Code, remains undisputed.

Cyberbullying amongst teenagers is a major issue, due to their increased use of social media. Previous literature surveys have not covered in detail cyberbullying studies in 2014 and cyberbullying risk factors. This literature review explores cyberbullying research areas, such as the use of social media by teenagers, themes from cyberbullying studies carried out since 2012, cyberbullying risk factors and how teenagers deal with cyberbullying incidents. Current cyberbullying studies highlighted issues such as the high volume of cyberbullying incidents in school, increased personal information disclosure on social media, peer influences and the safety of the school environment for both bully and victim. Studies focusing on cyberbullying risk factors raised debates on factors such as whether males or females are most likely to be victims/cyberbullies. Tackling cyberbullying requires awareness, education for actors involved in cyberbullying, development of software to detect cyberbullying and including actors in the monitoring of cyberbullying.

Purpose – The increasing complexity of the present economic system and the strong interdependencies existing between production activities taking place in different world areas make modern societies vulnerable to crisis. The global supply chain is a paradigmatic example of economic structures on which the impacts of unexpected events propagate rapidly through the system. Climate change, which affects societies all over the world, is one of the most important factors influencing the efficiency of the present economic networks. During the last decades a large set of studies have been oriented to investigate the direct impacts generated on specific geographical areas or productions. However, a smaller number of analyses have been oriented to quantify the cascading and indirect economic effects generated all over the world. The paper aims to discuss these issues. Design/methodology/approach – The main objective of this paper is to provide an overview of the main studies, methodologies and databases used to investigate the climate vulnerability of the global supply chain. Findings – The great complexity of the global economic system, coupled with methodological and data gaps, makes it difficult to estimate the domino effects of unexpected events. A clear understanding of the possible consequences generated all over the world is, however, a fundamental step to build socio-economic resilience and to plan effective adaptation strategies. Originality/value – The information provided in this paper can be useful to support further studies, to build consistent quantification methodologies and to fill the possible data gap.

Electricity markets have been established in many countries of the world. Electricity and services are traded in the competitive environment of electricity markets, which generates a large amount of information during the operation process. To maintain transparency and foster competition of electricity markets, timely and precise information regarding the operation of electricity market should be disclosed to the market participants through a centralized and authorized information disclosure mechanism. However, the information disclosure mechanism varies greatly in electricity markets because of different market models and transaction methods. This paper reviews information disclosure mechanisms of several typical electricity markets with the poolco model, bilateral contract model, and hybrid model. The disclosed information and clearing models in these markets are summarized to provide an overview of the present information disclosure mechanisms in typical deregulated power systems worldwide. Moreover, the various experiences for establishing an efficient information disclosure mechanism is summarized and discussed.

AbstractHuman longevity is rising rapidly all over the world, but are longer lives more satisfied lives? This study suggests that the answer might be no. Despite a substantial increase in months of satisfying life, people’s overall life satisfaction declined between 1985 and 2011 in West Germany due to substantial losses of life satisfaction in old age. When compared to 1985, in 2011, elderly West Germans were, on average, much less satisfied throughout their last five years of life. Moreover, they spent a larger proportion of their remaining lifetime in states of dissatisfaction, on average. Two important mechanisms that contributed to this satisfaction decline were health and social isolation. Using a broad variety of sensitivity tests, I show that these results are robust to a large set of alternative explanations.

This paper documents a positive correlation between the genetic distance to the world technological frontier (United Kingdom, United States) and the year of the onset of the fertility transition across countries. This result is robust to controlling for a large set of geographical, climatic, historical, and institutional variables. Two main mechanisms could explain this reduced-form relationship. First, genetic distance to the world technological frontier can affect the onset of the fertility transition through its impact on the timing and intensity of technology adoption. Second, genetic distance to the technological frontier can capture other cultural differences and the process of diffusion of cultural norms that are related to fertility but not through technology adoption. We find suggestive evidence supporting both mechanisms.
