Seasonal Adjustment Without Revisions A Real-Time Approach - Original PDF
نویسندگان: Barend Abeln · Jan P. A. M. Jacobs خلاصه: Preface In the 1980s, the first author was asked for information about profit prospects of a number of companies, in order to predict the change of their prices on the stock market. He looked up annual reports and recent interim results of these companies and noted that interim results consisted largely of a comparison of recent quarterly results to those of the same quarter of the preceding year. Moreover, stock prices reacted instantly to the outcomes of these comparisons. He was struck by the fact that these outcomes were frequently predictable: If there had been an up or down in the preceding year’s quarterly result, this would affect the comparison to the recent quarter. If last year’s ups or downs had been large, such as a profit on the sale of a construc- tion, or a depreciation of goodwill, these would be referred to in the comparison of the present quarterly report and would not come as a surprise and have little or no impact on stock prices. But if the market had become used to rising quarterly profits of Company X to the tune of say 1% over the preceding year, then an increment of ‘only’ 0.5% in the recent quarter would have a negative impact on the stock prices. Yet, this slight reduction in the profit’s increment may have its cause not in the present quarter, but in the preceding year or in the preceding few quarters. But then it is predictable

نویسندگان: Mehmet Güney Celbi ̧s · Karima Kourtit · Peter Nijkamp خلاصه: The recent COVID-19 experience has left deep traces in the urban fabric and has prompted a re-orientation regarding the future of cities. Is an urban overhaul on the way? And will digital technology erode conventional urban agglomeration advan- tages? The socioeconomic impacts of the pandemic will definitely leave their mark on cities. For example, the digital divide has already become more apparent regarding equitable access to education or to virtual libraries. Furthermore, climate change will have a stronger influence on cities than in the past, given that avoiding close indoor activities or reducing dense concentrations of people may become commonplace. For example, operating restaurants with outside dining areas or organizing open-air activities which allow safe social distancing will face new challenges in cities, in particular in places where weather conditions may become less favorable

Disaster Management and Information Technology Professional Response and Recovery Management in the Age of Disasters - Original PDF
نویسندگان: Hans Jochen Scholl • Eric E. Holdeman • F. Kees Boersma خلاصه: There is no one single journey when it comes to technology. For those who did not grow up as “digital natives” each has taken their own path in accepting, developing technological skills and expanding them by integrating them into their everyday work environment. Indeed, the journey continues with no hard- set destination before us. We only know that technological development and use of technology continue to expand exponentially with each passing day. What follows is therefore just one American perspective on how the profession of emergency management has adopted technologies over the decades in which the profession has existed. All the while, working daily to plan for, train, and practice for future emergency and disaster response events that are sure to come.
Intersectionality and Discrimination by Roger White - Original PDF
Intersectionality and Discrimination by Roger White - Original PDF
نویسندگان: Roger White خلاصه: Abstract We begin with a brief discussion of the relationship between social justice and economic justice. This is followed by a presentation of persistent differences in U.S. labor market outcomes. Specifically, we identify significant differences in unemployment rates and hourly wages across race- and sex-based classifications, respectively. We then present unadjusted wage gaps (i.e., raw differences in average hourly wage rates) for several worker groups that correspond to the non-productive personal characteristics we consider in this study. These characteristics include Hispanic ethnicity, nativity, race, and sex. Having motivated our study, we introduce intersectionality and our primary research question: Is wage discrimination intersectional? This is followed by a discussion of why we use the term “discrimination” when referring to differences in wage rates that cannot be explained by differences in workers’ productive character- istics. We conclude the chapter with a roadmap for the remainder of the book

نویسندگان: Karl Widerquist خلاصه: CHAPTER 1 Introduction As I went walking, a sign stopped me. On the one side, it said “No Trespassing.” But on the other side, it didn’t say nothing. That side was made for you and me. ... This land was made for you and me. —Woody Guthrie, “This Land Is Your Land” as covered by Remember Alice?1 Any conception of a right—whether legal or natural—has to be recip- rocal in the relevant ethic respect. A nonreciprocal “right” is merely a privilege. A right of self-ownership at least prima facie passes this test. It amounts to saying accept my ownership of my body as I respect your ownership of your body. The highly unequal ownership system that prevails in external assets (i.e., property in anything outside of our living bodies) prima facie fails this test in at least two ways. First, it gives one group control over resources essential to everyone’s survival and therefore, forces the propertyless group to perform services for the property-owning group to survive. Second, it amounts to saying, “You should respect my property for I would respect yours if you had any.

نویسندگان: An Islamic Finance Perspective خلاصه: CHAPTER 1 Affordable Housing and Poverty “The root causes of the problem in accessing affordable housing” In Islam, paying Zakat, avoiding Riba, and spending to avoid hoarding have much more value than abstaining from fornication, theft, and drinking. The hoarding issue has not been appropriately preached since Al-Ahbari has been hoarding.1 The importance, as well as the proper imposition of Zakat, is also ignored. Case Box 1.1 showcases the clari- fication from Muhammad ( ).

نویسندگان: Constantine Stephanidis, Margherita Antona, Stavroula Ntoa, Gavriel Salvendy خلاصه: 4 P. Asghari et al. 1 Introduction Eye tracking (ET) is frequently used, for example, in behavioral research and human-computer interaction. Eye movement patterns can reveal detailed infor- mation about the user’s cognitive processes, their attention level, or decision- making processes [3,12]. Applications and research based on ET require reliable and robust data [9]. Traditionally, this requires dedicated hardware with high- resolution cameras and infrared illumination to detect corneal reflections [7]. However, dedicated hardware is expensive and thus limits the pervasive use in real-world applications. This situation may change since, propelled by recent advances in deep learning, appearance-based gaze estimation methods that deliver promising results based on low-cost consumer-grade camera inputs start to emerge [2,10,11,21]. These approaches learn to estimate gazes from a video stream based on large-scale data sets and provide 3D gaze vectors or correspond- ing 2D gaze locations on a screen. Furthermore, they do not require any specific external devices and can be used with standalone computers, laptop built-in webcams, or mobile device consumer-grade cameras. This opens up the possi- bility of developing affordable automated intelligent ET solutions for research, commerce, and the general public. On the way to realize this ambition, webcam ET (wcET) has to address several challenges including gaze estimation accu- racy, gaze estimator prediction time, and that gaze estimation quality can be affected by user movements [11]. This paper aims to contribute to the first step toward utilizing wcET as a low-cost pervasive technology by validating the data quality of a state-of-the-art wcET approach in comparison to the performance of an established, commercially available dedicated eye tracking (dhET) system. Accordingly, we address the following research question in our work: How does the gaze estimates of wcET differ from dhET in practical settings regarding accu- racy, precision, and sampling rate? We will further discuss how the limitations of the data quality may affect the performance of wcET applications

نویسندگان: Gail E. Tompkins خلاصه: Young children write “All About . . .” books on familiar topics (Tompkins, 2012). They put together a booklet with four or five pages, write a sentence or two on each page, and add illustrations to elaborate the information presented in the text. Stu- dents read the book to the teacher, who helps them elaborate ideas and correct mechani- cal errors before they share from the author’s chair (see p. 10). As they gain experience writing books with one or two sentences per page, students can expand and elaborate the information they share on each page, gradually increasing the length to a paragraph

AN INTRODUCTION TO PERFORMANCE ANALYSIS OF SPORT - Original PDF
نویسندگان: PETER O’DONOGHUE خلاصه: This introductory chapter introduces sports performance analysis by asking the following questions: What? Why? Who? Where? When? and How? What is sports performance analysis? What are sports performance data and information? Why do we analyse sports performance? Who analyses sports performance? Where is sports performance analysis done? When is sports performance analysis done? How is sports perform- ance analysis done? The answers to these questions are not independent. The reason why sports performance analysis is done and who requires the information can dictate what information is required. The informa- tion required can in turn influence when it is needed and thus when sports performances should be analysed. The time at which information is needed and economic constraints dictate the methods and locations of sports performance analysis tasks. These questions will be answered in turn but readers can expect some necessary overlap between the answers.
