The development of industrial pensions in the United States in the twentieth century

Pensions are retirement income. They offer protection in case you live long enough to quit collecting a paycheck and can stop working. In the United States, pensions are provided by both public and private sectors. Private sector pension funds are the largest formal financial institution for life-cycle saving, with assets of trillions of dollars. Pensions developed when more traditional forms of life-cycle saving became more difficult to carry out, job tenure increased, and there was a movement away from the spot labor market. Employers wanted to create a stable, experienced work force that was reluctant to leave - that is, a stock of firm-specific human capital. Thus they had an incentive to create a deferred wage. And workers wanted retirement insurance that was secure. As developing countries begin to employ an older work force with longer job tenure, the demand for defined benefit pensions will rise. Which institution can best provide pensions: the employer, a financial intermediary, or the state? If markets fluctuate because of financial instability, workers will prefer defined benefit plans, and they will want them to be provided by the institution in which they have the most faith. Funding is important in the long run. Sound accounting practices would dictate that the cumulative reserves match pension liabilities as they accumulate. The regular contribution to these funds would be the deferred wage. But historically, in the United States, pensions were funded only when profits were high or tax incentives or regulation dictated. Developing countries will need a sound corporate tax structure and must be willing to forgo some immediate tax revenue, to create a large pension savings fund.Public Health Promotion,Banks&Banking Reform,Pensions&Retirement Systems,Health Monitoring&Evaluation,Municipal Financial Management,Banks&Banking Reform,Pensions&Retirement Systems,Health Monitoring&Evaluation,Municipal Financial Management,Gender and Law

The Emergent Vinifera Wine Industry in North Carolina: A Descriptive Overview

The North Carolina (NC) wine industry has grown rapidly over the past decade and is expected to grow even more as the worldwide wine consumption and export of wines rises. In the United States, the wine market has grown by 13.7 percent since 2002 in volume and by more than 15 percent in dollars as wine has progressed from being a beverage of an elite segment of the market to becoming a mainline beverage, taking its place alongside beer and liquor (MKF Research LLC, 2007; Oches, 2009). The Piedmont Triad Region is uniquely positioned to increase its presence in this industry. Of the 80 wineries in NC that are currently open to the public, nearly half are located in the Piedmont Triad Region. However, growing grapes and making wine is a long term commitment to a community, both financially and physically. The MKF Research report states that the capital-intensive nature of the winery and vineyard sectors is often underestimated, with new entrants to the industry at times unprepared for the extended cash requirements. In addition, only a few local institutions are familiar with the unique needs of the winemaking business. In order to address factors that will impede growth in this nascent industry, it is important to identify the state of the industry and obtain management perspectives on the needs and challenges facing their operations. This study provides information that would help gain a better understanding of the business issues and needs related to the wine and grape industry in North Carolina. Data for this study was drawn from a census of 34 wine producers located in the Yadkin, Swan Creek, and the Haw River valley regions of North Carolina. Descriptive statistics using frequencies and means is used to provide a demographic overview of the industry and to identify the factors that wine producers perceive to be important in affecting their profitability. Results from the study shows that most of the wineries share some common traits: they are small, relatively new to the wine and grape industry and grow grapes other than the traditional native Muscadine grape. Primarily, a majority of the wineries are family-based entrepreneurial businesses that have to behave like mini-conglomerates. These findings are consistent with a study conducted by Taplin and Breckenridge (2008).Profitability Constraints, Financial Management, Marketing, Distribution, Agribusiness, Community/Rural/Urban Development, Farm Management,

Determinants of Sexual Activity and Its Relation to Cervical Cancer Risk among South African Women

BACKGROUND. Invasive cervical cancer is the commonest cause of cancer morbidity and mortality in South African women. This study provides information on adult women's sexual activity and cervical cancer risk in South Africa. METHODS. The data were derived from a case-control study of hormonal contraceptives and cervical cancer risk. Information on age of sexual debut and number of lifetime sexual partners was collected from 524 incident cases and 1541 hospital controls. Prevalence ratios and adjusted prevalence ratios were utilised to estimate risk in exposures considered common. Crude and adjusted relative risks were estimated where the outcome was uncommon, using multiple logistic regression analysis. RESULTS. The median age of sexual debut and number of sexual partners was 17 years and 2 respectively. Early sexual debut was associated with lower education, increased number of life time partners and alcohol use. Having a greater number of sexual partners was associated with younger sexual debut, being black, single, higher educational levels and alcohol use. The adjusted odds ratio for sexual debut < 16 years and ≥ 4 life-time sexual partners and cervical cancer risk were 1.6 (95% CI 1.2 – 2.2) and 1.7 (95% CI 1.2 – 2.2), respectively. CONCLUSION. Lower socio-economic status, alcohol intake, and being single or black, appear to be determinants of increased sexual activity in South African women. Education had an ambiguous effect. As expected, cervical cancer risk is associated with increased sexual activity. Initiatives to encourage later commencement of sex, and limiting the number of sexual partners would have a favourable impact on risk of cancer of the cervix and other sexually transmitted infections.National Cancer Institute (R01 CA 73985

Design of a Digital Game-Based Learning Environment for Solving Quadratic Equations Using Completing-the-Square-Method

Various preconceptions about the effectiveness of applying digital-games approach in tandem with traditional teaching methods subsist in spite of learners increasing usage of digital devices and digital games. This trend obviously underplays the existing technological advancements made in respect to digital devices and computer game programming. This research paper applied the digital game approach to the teaching of mathematics with a view to boosting learner’s interest while mitigating boredom, difficulty and apprehension towards solving problems. It employed story-telling technique and role-play (both fun elements) to mathematics learning while still preserving the traditional stepwise approach to problem-solving in mathematics. A digital game-based environment was developed based on the battleship game. This environment was used to learn how to solve the quadratic equation using completing the square method. Performance evaluation was carried out to determine if the system aligns with the underlined objectives. The findings showed that using the digital game-based learning system helps in reducing learners’ apprehension in solving the quadratic problem and improved their cognitive skills in solving quadratic equations

GILP: An Interactive Tool for Visualizing the Simplex Algorithm

The Simplex algorithm for solving linear programs-one of Computing in Science & Engineering's top 10 most influential algorithms of the 20th century-is an important topic in many algorithms courses. While the Simplex algorithm relies on intuitive geometric ideas, the computationally-involved mechanics of the algorithm can obfuscate a geometric understanding. In this paper, we present gilp, an easy-to-use Simplex algorithm visualization tool designed to explicitly connect the mechanical steps of the algorithm with their geometric interpretation. We provide an extensive library with example visualizations, and our tool allows an instructor to quickly produce custom interactive HTML files for students to experiment with the algorithm (without requiring students to install anything!). The tool can also be used for interactive assignments in Jupyter notebooks, and has been incorporated into a forthcoming Data Science and Decision Making interactive textbook. In this paper, we first describe how the tool fits into the existing literature on algorithm visualizations: how it was designed to facilitate student engagement and instructor adoption, and how it substantially extends existing algorithm visualization tools for Simplex. We then describe the development and usage of the tool, and report feedback from its use in a course with roughly 100 students. Student feedback was overwhelmingly positive, with students finding the tool easy to use: it effectively helped them link the algebraic and geometrical views of the Simplex algorithm and understand its nuances. Finally, gilp is open-source, includes an extension to visualizing linear programming-based branch and bound, and is readily amenable to further extensions.Comment: ACM SIGCSE 2023 Manuscript, 13 pages, 5 figure
