Abstract In recent years, the e-commerce market has grown with the spread of the internet worldwide every year. Accordingly, in service industries, purchasing products with reservations has become common. With the spread of online reservations, the booking curve, which is the concept of the time series in the cumulative number of reservations and has been used for sales optimization in the airline ticket and hotel industries, has been used in various industries. Booking curves in specific industries have been studied, but a universally applicable model across various industries has not been developed. In this study, we show that booking curves can be modeled universally by the exponential decay function, and we also show that the model is valid by using real data from some industries before and after the COVID-19 pandemic, that is, under completely different market conditions. The cross-industry exponential laws of booking curves constitute an important discovery in regard to mathematical laws in the social sciences and can be applied to give leading microeconomic indicators.

Diagnostic Hysteroscopy

ABSTRACT Objective: To evaluate the intensity of pain reported by patients undergoing outpatient diagnostic hysteroscopy. Methods: Exam performed with a 5-mm lens hysteroscope, vaginal speculum, tenaculum and uterine distention with carbon dioxide gas. Before and after the examination, patients were interviewed to define, in a verbal scale from 0 to 10, pain values that they expected to feel and that they experienced after the end, and also if they would repeat it if indicated. Data were analyzed using Statistical Package for the Social Sciences 15.0, statistic significance was defined as p < 0.05 with a study power of 95%. Results: Fifty-eight patients were included with mean age of 50.9 years, with 32.8% at postmenopause and 6.9% nulliparous. Among those with previous deliveries, mean parity was 2.21 and at least one vaginal delivery had occurred in 63.8%. Only 24.1% of patients knew how the exam would be done, 62.1% needed an endometrial sample and the result was considered satisfactory in 89.7%. The means of expected and experienced pain were similar (6.0 versus 6.1), and 91.4% of women would repeat the hysteroscopy if necessary. The only factor associated with less pain after the exam was previous vaginal delivery, with a decrease of pain score from 7.1 to 5.5 (p = 0.03). Mean pain was significantly lower in those who agreed to repeat the exam (5.8 versus 9.4; p = 0.003). Conclusions: Outpatient diagnostic hysteroscopy with gas can be associated with moderate but tolerable discomfort and satisfactory results.

This paper retraces the debates on life-histories before and after the linguistic turn in the social sciences, and, more specifically, in the anthropological tradition. It stresses how poststructuralist feminist methodological, theoretical, and political appropriations of personal narratives represent a significant textual intervention in the gendered social-cultural scripts of women’s lives.

Research over the past 15 years has examined how the Internet is being used to support communication and social interaction across a variety of groups and communities. However, much of this research has been exploratory, rather than explanatory. It is argued here that approaches from the social sciences offer established methods and frameworks within which the psychological and social impacts of computing can be addressed. In discussing various theories, the chapter highlights one problem—that individual theories have tended to be used to explain a single aspect of human behaviour. There is a need to think more holistically and search for a theoretical approach that can explain intrapersonal processes (e.g. cognition and emotion) as well as interpersonal behaviour within social computing. A number of theoretical frameworks from the social sciences (e.g. social identity theory and social capital theory) will be discussed as potentially being able to explain psychological processes at all levels for users of social computing applications. In summary, the objectives of this chapter are to discuss current approaches used to explain the way people interact in social computing contexts, identify shortcomings with these and to highlight approaches that can address these shortcomings.

The purpose of the present study was to examine areas of interest and information seeking patterns of Israeli 12th graders who engaged in research work for their final research paper, an optional partial requirement for obtaining an official matriculation diploma. A detailed questionnaire, based on former studies was disseminated in high schools all over the country, yielding 200 usable questionnaires. Main findings: topping the list of chosen topics were the humanities (44%), followed by the sciences (33%), and the social sciences (24%). Considerable differences were found between girls and boys. Girls preferred topics from the social sciences (mainly sociology) and from the humanities (except history) while boys preferred scientific topics. Most respondents had a computer at home (93%) which was usually connected to the Internet (78%) and they had taken some computer course in the past (70%) although a considerable proportion, more girls than boys, did not make use of them. Gender was found to be significantly associated with the chosen field. Taking a computer course and use of home Internet were found to be associated with searching the Internet in the process of information seeking while working on the final paper. A home computer connected to the Internet was associated with the use of formal and informal information sources. The school library was the most-visited one followed by academic, public and home libraries. However, a considerable proportion of the respondents reported no or few visits only. Most respondents reported receiving only little or no advice and guidance regarding the library and database searching. When guidance was provided, it usually consisted of a single-session on a personal basis. Guidance given by a teacher was frequently face to face, with the student more likely to use an OPAC, while when given by a university teacher it was usually in front of a computer, followed by lesser use of OPACs. In summation, although most students were aware of powerful new IT tools, their use is not as prevalent as may be assumed, mainly due to poor or inadequate guidance.

Agent-Based Simulation (ABS), an interdisciplinary area embracing both the computer science and the social science, has attracted much attention and aided the understanding of socially complex phenomena. A current important issue in this research area is how to improve ABS effectiveness and comprehension, which makes further mutual influence between the computer science and the social sciences indispensable - e.g., (1) agent modeling involving learning mechanisms in the computer science and (2) social dynamics analysis needed in the social science. Such integration of these two areas would help fulfill the great potential of ABS, first in solving complex engineering problems using agent-based technology and second in developing and testing new theories on socially complex systems. This special issue features ABS papers from both of these important areas exploring new trends in ABS. The 10 papers composing this special issue start with papers by Nobutada Fujii and Hiroyasu Inoue analyzing the relationship between the network structure and system dynamics. In these papers, an agent-based computational economics approach has been active in applying agent-based technologies to financial and economic systems. Papers by Biliana Alexandrova-Kabadjova, Isamu Okada, TomokoOhi, and Nariaki Nishino cover consumer and financial markets using agent-based models. They test economic theory and examine market phenomena for market design. Agent-based simulation is increasingly used in application fields in the social sciences. Papers by Kiyoshi Izumi, Hideki Fujii, Hiromitsu Hattori, and Shigeo Sagai propose solutions for actual social problems such as injury prevention, traffic, and electrical power. Models are created based on behavior data, and the integration of an agent-based model and real data is a hot topic in this area. As the beginning of these technical papers, this issue starts by a position paper to give an ABS overview for understanding important issues in ABS from an overall viewpoint and for understanding state-of-the-art ABS. The information presented is invaluable in helping readers grasp the important features of ABS.

Cross Recurrence Plot

Abstract. The method of recurrence plots is extended to the cross recurrence plots (CRP) which, among others, enables the study of synchronization or time differences in two time series. This is emphasized in a distorted main diagonal in the cross recurrence plot, the line of synchronization (LOS). A non-parametrical fit of this LOS can be used to rescale the time axis of the two data series (whereby one of them is compressed or stretched) so that they are synchronized. An application of this method to geophysical sediment core data illustrates its suitability for real data. The rock magnetic data of two different sediment cores from the Makarov Basin can be adjusted to each other by using this method, so that they are comparable.

AbstractThis paper discusses the problems of the Islamization of modernity that are mostly ignored in the social sciences on the topic of Islam. The case study deals with a transnationalized Turkish-Islamic group of the followers of the populist theologian Said Nursi in Germany. The author presents an outline of the community character and interprets also the reactions of the community in the cross-cultural field in the aftermath of September 11, with regard to this specific culture of the group. In conclusion, he draws attention to the question of how the Islamic reformists imagine the host societies in Europe and of which symbolic repertoire has been used to connect on the current integration discourse.

Quantum Event

Quantum physics is being positioned as a new archive for addressing major theoretical problems in the field of international relations. Two of the major proponents of engaging quantum thinking within international relations, James Der Derian and Alexander Wendt, have argued that quantum thinking offers the possibility of a major paradigm shift in the field. Before we determine quantum’s revolutionary potential, the persistent and most pressing question for me is how to position quantum thinking among other kinds of and claims to knowledge. I want to horizontalize where different kinds of knowledge sit within the renewed attention to quantum theory. Rather than just horizontalize or flatten ontology, I want to see what happens when we place scientific and philosophical inquiry in dialogue, and what that conversation does to the authority and value of quantum thinking for the social sciences. The article reconstructs the dialogue between the first generation of quantum physicists and the philosophers who informed them. Rather than make an explicit argument about the philosophical debt of physics, I argue that a broad and highly interdisciplinary set of questions drove both fields well beyond the specific areas of expertise of any of these thinkers. I believe this adventure of ideas followed by physicists, philosophers, and social theorists alike offers us a way forward as the complexity of our contemporary global challenges confront us now with the necessity to think well beyond our disciplinary expertise.

The Way

ABSTRACTSince its beginning, archaeology stands between the natural sciences and the social sciences and humanities. This shared position and the search for a greater understanding of its specific study objects, created the need among archaeology experts to resort to various methods (and technologies) originated from other disciplines. Similarly to other sciences, archaeology is an area permeable to experimentation and application of theoretical and practical exogenous concepts. This lead to the development of several specializations that unite archeology and other areas, such as Zooarchaeology. As happened throughout its history, academics are facing a time of change in the way the acquisition of knowledge is processed. The Digital Era of globalization is related to the shifting of paradigms and the growing need for unceasing adaptation; archeology is also affected by this reality. After a brief introduction to the humanities "digital paradigm" we review some of the main uses of the Internet as a support to research development in archeology, their main obstacles and tendencies.RESUMODesde a sua génese, a Arqueologia encontra-se entre as ciências naturais e as ciências sociais e humanísticas. Esta posição partilhada e a procura de uma maior compreensão dos seus objetos de estudo específicos, criou nos profissionais de Arqueologia uma necessidade de recorrerem a várias metodologias (e tecnologias) originárias de outras disciplinas. De forma similar a outras ciências, a Arqueologia é uma área permeável à experimentação e aplicação de conceitos teórico-práticos exógenos que levou, inclusive, à formação de diversas especialidades que unem a Arqueologia e outras áreas, como a Zooarqueologia. Como aconteceu ao longo da sua história, o meio académico está perante um momento de mudança na forma como se processa a aquisição de conhecimento. O fato de estarmos na Era Digital da globalização faz com que a adaptação do meio académico a esta realidade seja mais continuada, não sendo a Arqueologia alheia a esta transformação. Após uma breve introdução ao novo "paradigma digital" das humanidades, revemos alguns dos principais usos de tecnologias relacionadas com o uso da Internet no apoio à investigação em Arqueologia (e.g., bases de dados enriquecidas), e descrevemos algumas questões relacionadas com o uso de novas ferramentas e técnicas, seus principais obstáculos e tendências.
