Abstract

Is the United States in decline? If so, what are the causes and dimensions of that decline and is it irreversible? Will American decline be accompanied by the rise of a new hegemon? To what extent are that rise and decline merely concurrent processes, determined by forces internal to each polity, or are American decline and the rise of its competitors both manifestations of a single global dynamic?

This introduction defines decline and presents the answers to those questions offered by the authors of the chapters in this volume. I conclude by analyzing the effects of internal US decline upon the global economy and geopolitics and offer an agenda for future research on politics and nationalism in a post-hegemonic world.

Abstract

Purpose: This chapter aims to examine machine learning (ML) models for predicting credit card fraud (CCF).

Need for the study: With the advance of technology, the world is increasingly relying on credit cards rather than cash in daily life. This creates a slew of new opportunities for fraudulent individuals to abuse these cards. As of December 2020, global card losses reached $28.65billion, up 2.9% from $27.85 billion in 2018, according to the Nilson 2019 research. To safeguard the safety of credit card users, the credit card issuer should include a service that protects customers from potential risks. CCF has become a severe threat as internet buying has grown. To this goal, various studies in the field of automatic and real-time fraud detection are required. Due to their advantageous properties, the most recent ones employ a variety of ML algorithms and techniques to construct a well-fitting model to detect fraudulent transactions. When it comes to recognising credit card risk is huge and high-dimensional data, feature selection (FS) is critical for improving classification accuracy and fraud detection.

Methodology/design/approach: The objectives of this chapter are to construct a new model for credit card fraud detection (CCFD) based on principal component analysis (PCA) for FS and using supervised ML techniques such as K-nearest neighbour (KNN), ridge classifier, gradient boosting, quadratic discriminant analysis, AdaBoost, and random forest for classification of fraudulent and legitimate transactions. When compared to earlier experiments, the suggested approach demonstrates a high capacity for detecting fraudulent transactions. To be more precise, our model’s resilience is constructed by integrating the power of PCA for determining the most useful predictive features. The experimental analysis was performed on German credit card and Taiwan credit card data sets.

Findings: The experimental findings revealed that the KNN achieved an accuracy of 96.29%, recall of 100%, and precision of 96.29%, which is the best performing model on the German data set. While the ridge classifier was the best performing model on Taiwan Credit data with an accuracy of 81.75%, recall of 34.89, and precision of 66.61%.

Practical implications: The poor performance of the models on the Taiwan data revealed that it is an imbalanced credit card data set. The comparison of our proposed models with state-of-the-art credit card ML models showed that our results were competitive.

Abstract

 : Immigration in the colonial period was almost exclusively English plus geographically scattered others. Little immigration until after the War of 1812, still mainly English speaking. After 1840, a heavy influx of German (1850–1880), Irish, later Scandinavian immigrants in large numbers, especially after, but also during, the Civil War, 1860–1865. The heaviest immigration was from 1890 through 1910 up to World War I: Polish, Italian, Slavic, Russian and Romanian Jews, generally East European. Most immigrants were young people. Since World War I immigration has been light, due in part to restrictive policies after 1920, especially after 1927. Only slight immigration during the 1930s but more emigration, resulting in net emigration. Since World War II, considerable immigration but nothing like the period prior to World War I; relatively geographical distributed: refugees, nationals, displaced persons, etc., including the families of servicemen who married abroad.

Abstract

Despite being the standard against which all other offshore work sites are compared, the male-dominated work culture of the Gulf of Mexico has received little attention from social scientists. Drawing on the literature on women and work in the United States, on women in the U.S. South, in the military, and in the oil field, and on interviews with hundreds of individuals this paper explores the roles of women in the development and maintenance of the offshore oil and gas industry in southern Louisiana.

Abstract

National parks are selected as places of national importance, with national meaning. At the same time, the political process that shapes park management is often a local one. This biases park interpretation away from national concerns and toward local ones. The National Park Service's corporate interests and decision-making processes often reinforce the role of local interests except in the rare cases of congressional intervention. A close look at the political environment of Fort Davis National Historic Site, Texas, illustrates these points. Congress mandated the site to interpret westward expansion and its impact on American Indians. It became instead a program of park interpretation based on westward expansion and the role of African-American “Buffalo Soldiers” within it. As a result, Indians have effectively been written out of the story of this “Indian fort.” Interestingly, Native American issues reappear in commercial establishments, both the gift shop in the park and businesses in the town of Fort Davis outside the park. If businesses perceive a demand for information about Native Americans among tourists, presumably there is a similar, unmet demand among the same tourists as they visit the historic site. Given the role of local concerns in park interpretation, national intervention will probably be necessary to provide political support for reinterpreting the site.

Abstract

Barriers to adequate healthcare in rural areas remain a grand challenge for local healthcare systems. In addition to patients' travel burdens, lack of health insurance, and lower health literacy, rural healthcare systems also experience significant resource shortages, as well as issues with recruitment and retention of healthcare providers, particularly specialists. These factors combined result in complex change management-focused challenges for rural healthcare systems. Change management initiatives are often resource intensive, and in rural health organizations already strapped for resources, it may be particularly risky to embark on change initiatives. One way to address these change management concerns is by leveraging socio-technical simulation models to estimate techno-economic feasibility (e.g., is it technologically feasible, and is it economical?) as well as socio-utility feasibility (e.g., how will the changes be utilized?). We present a framework for how healthcare systems can integrate modeling and simulation techniques from systems engineering into a change management process. Modeling and simulation are particularly useful for investigating the amount of uncertainty about potential outcomes, guiding decision-making that considers different scenarios, and validating theories to determine if they accurately reflect real-life processes. The results of these simulations can be integrated into critical change management recommendations related to developing readiness for change and addressing resistance to change. As part of our integration, we present a case study showcasing how simulation modeling has been used to determine feasibility and potential resistance to change considerations for implementing a mobile radiation oncology unit. Recommendations and implications are discussed.

Abstract

Purpose

The purpose of this paper is to examine the gendered processes of ageing at work in Switzerland, a country already characterised by particularly high employment rates for seniors of both sexes, and where the notion of “active ageing” has recently appeared on the policy agenda. The study illustrates the mechanisms through which men and women accumulate dis-/advantage across the life course, and the influence that critical events in different life domains have on the conditions under which they prepare the transition to retirement.

Design/methodology/approach

The data used in the paper were collected with a mixed methods approach, including secondary statistical data analysis, expert interviews (with human resource and line managers), company case studies and 63-biographical interviews with male and female seniors employed in three different sectors (food distribution, health, transport) of the Swiss labour market. The interview guide covered issues relating directly to the employment histories and working conditions of the over 50s, but also enabled respondents to reflect on the influence of past or recent events in their private lives on their experiences of ageing at work (and vice versa).

Findings

The study shows that, in the Swiss context, ageing at work is a social experience, that is profoundly marked by societal-level normative “gender scripts” and by the gendered nature of major life-course transitions. However, rather than producing a clear distinction between the experiences of men on the one hand and women on the other, studying the accumulation of dis-/advantages (Dannefer, 2009) enables us to elaborate a more nuanced typology, mapping the Swiss experience of ageing at work according to four alternative ideal-type models: confident, resentful, determined and distressed.

Social implications

In a context characterised by prolonged life expectancy and restricted welfare budgets, a clearer understanding of the conditions under which men and women make decisions about the continuation, interruption or adaptation of their professional activities (and care commitments) in the second half of their adult lives has clear implications, both for patterns of “active ageing” and for gender equality.

Originality/value

The paper sheds new light on the gendered variations in the experience of ageing at work in the Swiss context; it examines the implications of the dis-/advantages accumulated by different categories of men and women during various transitions in the employment and family spheres on their autonomy, well-being and satisfaction during this critical period of their adult lives.
