Good Light for Good Sight

Let\u27s be eye conservationists. Since we have only one pair of eyes to last us a lifetime it is better to strengthen the eyesight by normal, healthful use than to weaken it by straining to get along under bad lighting conditions

AN ANALYSIS OF THE PROFILES AND MOTIVATIONS OF HABITUAL COMMODITY SPECULATORS

The focus of this study is the habitual speculator in commodity futures markets. The speculator's activity broadens a market, creates essential liquidity, and performs an irreplaceable pricing function. Working knowledge of the profiles and motivations of habitual speculators is essential to both market theorist and policy makers. Responses to a 73 question survey were collected directly from retail commodity brokers with offices in Alabama. Each questionnaire recorded information on an individual commodity client who had traded for an extended period of time. The typical trader studied is a married, white male, age 52. He is affluent and well educated. He is a self-employed business owner who can recover from financial setbacks. He is a politically right wing conservative involved in the political process. He assumes a good deal of risk in most phases of his life. He is both an aggressive investor and an active gambler. This trader does not consider preservation of his commodity capital to be a very high trading priority. As a result, he rarely uses stop loss orders. He wins more frequently than he loses (over 51% of the time) but is an overall net loser in dollar terms. In spite of recurring trading losses, he has never made any substantial change in his basic trading style. To this trader, whether he won or lost on a particular trade is more important than the size of the win or loss. Thus he consistently cuts his profits short while letting his losses run. He also worries more about missing a move in the market by being on the sidelines than about losing by being on the wrong side of a market move; i.e., being in the action is more important than the financial consequences. Participating brokers confirmed that for the majority of the speculators studied, the primary motivation for continuous trading is the recreational utility derived largely from having a market position.Marketing,

A Concept Paper for a VCU Social Sciences Initiative

This project proposes the development of a Social Sciences Initiative at the undergraduate and graduate levels that will provide educational, research and service opportunities for faculty and students. These opportunities are envisioned as interdisciplinary, with a focus on community issues and priorities, and with the potential to create new links among existing educational/research units within the University. The development of a Social Sciences Initiative provides a direct link to the Mission of VCU through several of the Mission’s intents: “activities that increase knowledge and understanding of the world and inspire and enrich teaching” The Social Sciences Initiative will expand current activities and promote innovative teaching in an interdisciplinary manner. “diverse educational programs” The Social Sciences Initiative increases the diversity of educational program offerings. “development of innovative approaches to meet the changing needs of our society” The Social Sciences Initiative will directly address the changing societal needs through support of interdisciplinary education, research, and service. Further, this initiative is consistent with the VCU Vision in that it will “advance a climate of scholarly inquiry…serve as a model of diversity in higher education…addressing urban issues in the nation and the world…build upon its substantial foundations in the…applied social sciences.” (VCU Strategic Plan for the Future of Virginia Commonwealth University, Phase II, 1998)

Math 120BC – Precalculus

Corporate reporting provides insight into companies’ commitment to genderequality

Many companies in Germany must provide information beyond financial figures in their annual reports. For some years now, legislators have increasingly required information on non-financial aspects, such as the shares of women in leadership positions. Using a quantitative text analysis of annual reports, this second report in the 2023 DIW Berlin Women Executives Barometer shows that the major publicly listed corporations in Germany implement the reporting requirements very differently. Reporting about women and leadership positions increased overall between 2009 and 2020 in line with the requirements. However, there were clear differences in the companies’ focus: There is an equality-oriented group of companies that reports extensively about concrete measures to increase the share of women in leadership positions. This group has significantly more women on their supervisory boards than the other group, compliance-oriented companies, which seem to be mainly concerned with fulfilling the legal requirements. Companies’ reporting on women and leadership positions is thus an indicator and useful signal to outside stakeholders of how serious companies are about gender equality

A Case Study Comparing Student Experiences and Success in an Undergraduate Mathematics Course offered through Online, Blended, and Face-to-Face Instruction

A research study was conducted at an undergraduate college, comparing student experiences and successes in a mathematics course offered fully online, blended and face-to-face. In online courses, students enjoy the flexibility of learning at their own pace, not having to travel to school, as well as having consistent access to courses through a web browser. However, such conveniences do not automatically produce positive results. Some students lack the discipline, enthusiasm and sometimes feel socially isolated from their peers when learning online. Despite these challenges, online courses continue to be developed in response to the demand for online learning opportunities. However, there is a need to determine the impact of these opportunities on student learning. The majority of the participants in this study were satisfied with their learning experience. Furthermore, the results analysis did not find enough evidence to confirm that there were any significant differences in the achievement, as measured by students’ final grades and exam scores based on whether the course was taught online, as a blended course, or face-to-face format. The researchers, therefore, concluded that students can attain the same level of academic achievement through online, blended, or face-to-face courses (measuring the final exam and course final grades)

Prey encounters and spatial memory influence use of foraging patches in a marine central place forager

This study was carried out as part of the Moray Firth Marine Mammal Monitoring Programme, a joint industry, academic and government strategic research project with funding from Beatrice Offshore Wind Ltd and Moray Offshore Renewables Ltd (MORL).Given the patchiness and long-term predictability of marine resources, memory of high-quality foraging grounds is expected to provide fitness advantages for central place foragers. However, it remains challenging to characterize how marine predators integrate memory with recent prey encounters to adjust fine-scale movement and use of foraging patches. Here, we used two months of movement data from harbour seals (Phoca vitulina) to quantify the repeatability in foraging patches as a proxy for memory. We then integrated these data into analyses of fine-scale movement and underwater behaviour to test how both spatial memory and prey encounter rates influenced the seals' area-restricted search (ARS) behaviour. Specifically, we used one month's GPS data from 29 individuals to build spatial memory maps of searched areas and archived accelerometery data from a subset of five individuals to detect prey catch attempts, a proxy for prey encounters. Individuals were highly consistent in the areas they visited over two consecutive months. Hidden Markov models showed that both spatial memory and prey encounters increased the probability of seals initiating ARS. These results provide evidence that predators use memory to adjust their fine-scale movement, and this ability should be accounted for in movement models.PostprintPeer reviewe
