Migrating existing multimedia courseware to Moodle

Open source course management systems offer increased flexibility for instructors and instructional designers. Communities can influence the development of these systems and on an individual basis, the possibility to modify the system software exists. Migrating existing courseware to these systems can therefore be beneficial, sometimes even required. We report here about our experience in migrating an existing courseware system consisting of multimedia content and interactive, integrated infrastructure functionality to an open source course management system called Moodle. We will assess the difficulties that we have encountered during this process and, discuss the importance of standards in this context, and we aim to provide other instructors or instructional designers with guidelines and assessment support for other migration projects

Treatment of Travel Expenses by Golf Course Patrons: Sunk or Bundled Costs and the First and Third Laws of Demand

To attract golf patrons, sport managers must understand consumption patterns of the golfer. Importantly, the treatment of travel costs must be understood. According to the Alchian-Allen (1964) theorem, golfers treat travel costs as bundled costs (third law of economic demand) whereas classical consumer theory indicates that golfers treat travel costs as sunk costs (first law of economic demand). The purpose of this study was to determine if golf patrons treated travel costs as sunk costs or if they treated travel costs as a bundled cost. Data from a survey of course patrons in Ohio support the treatment of travel costs as bundled costs by golf course patrons, especially those classified as tourists. Managers should utilize geographic segmentation in choosing whom to market their course based upon their product’s price compared to area competitors, as shown by the strong, positive correlation found between distance traveled and cost of green fees.Alchian-Allen Theorem; Third Law of Demand; Golf Tourism; Bundling

Major League Baseball and Globalization: The World Baseball Classic

In addition to generating initial profits, the WBC has positioned MLB to be the leader in growing the game of baseball and the commercial aspects of the sport throughout the world. As baseball grows, and more importantly as the American brand of baseball grows, it will be interesting to watch the worldwide reaction – particularly if MLB begins to generate huge profits overseas. Other prominent American brands such as Coke, Nike, Disney, and McDonalds have been both embraced and scorned as they have ventured beyond the fifty U.S. states. MLB will have unique challenges, but also tremendous opportunities as they attempt to expand their potential marketplace from 330 million consumers to the entire world. Ultimately, the long-term impact of the initial World Baseball Classic will not be known for many years, but it appears that the initial tournament met, and in some cases, exceeded expectations.World Baseball Classic; WBC; globalization

Free Ride, Take it Easy: An Empirical Analysis of Adverse Incentives Caused by Revenue Sharing

A fundamental belief in professional sport leagues is that competitive balance is needed to maximize demand and revenues; therefore, leagues have created policies attempting to attain proper competitive balance. Further, research posits that objectives of professional sport teams’ owners include some combination of winning and profit maximization. Although the pursuit of wins is a zero sum game, revenue generation and potential profit making is not. This article focuses upon the National Football League’s potential unintended consequences of creating the incentive for some teams to free ride on the rest of the league’s talent and brand. It examines whether an owner’s objectives to generate increased revenues and profits are potentially enhanced by operating as a continual low-cost provider while making money from the shared revenues and brand value of the league. The present evidence indicates that, overall, being a low-cost provider is more profitable than increasing player salaries in an attempt to win additional games.free riding; free ride; football; profit maximization; regression; owner incentives

Variable Ticket Pricing in Major League Baseball

Sport teams have historically been reluctant to change ticket prices during the season. Recently, however, numerous sport organizations have implemented variable ticket pricing in an effort to maximize revenues. In Major League Baseball, variable pricing results in ticket price increases or decreases depending on factors such as quality of the opponent, day of the week, month of the year, and for special events such as opening day, Memorial Day and Independence Day (July 4). Using censored regression and elasticity analysis, this paper demonstrates that variable pricing would have yielded approximately $590,000 per year in additional ticket revenue for each Major League team in 1996, ceteris paribus. Accounting for capacity constraints, this amounts to only about a 2.8$1.4 million in revenue. The largest percentage revenue gain would have been the San Francisco Giants. The Giants would have seen an estimated 6.7% increase in revenue had they used optimal variable pricing.baseball; variable pricing; dynamic pricing; regression; censored regression

Revenue and Wealth Maximization in the National Football League: The Impact of Stadia

The opening of the Palace of Auburn Hills, the SkyDome, and Oriole Park at Camden Yards led to the beginning of a construction boom in professional sport. In the National Football League (NFL) alone, 26 stadiums have been built or renovated in the past 10 years. Due to the additional revenue generated by these facilities and the NFL’s current revenue sharing system, professional football franchises are building new stadia for economic reasons rather than to replace unusable or unsafe facilities. The purpose of this study was to determine if a significant difference in net revenue change existed for NFL teams that moved into a new facility and to determine if there was a significant change in valuation for these franchises. The findings indicated that new stadia significantly increase revenue and franchise value in the NFL; therefore, the primary goal of every firm, wealth maximization, is met for teams after opening a new facility.football; NFL; stadium; revenue; honeymoon

Major League Baseball Anti-Trust Immunity: Examining the Legal and Financial Implications of Relocation Rules

Major League Baseball (MLB) rules restrict the movement of any franchise into another’s territory. These territorial rules are designed to protect each team’s potential local revenue sources as well as to provide stability throughout the league. Recently, Major League Baseball approved financial compensation for the Washington Nationals move into the Baltimore Orioles’ territory – primarily because it was in the best interest of MLB even though it hurt the Orioles. However, the Oakland Athletics were unable to even negotiate a potential compensation plan for a move into the San Francisco Giants territory, despite the apparent financial benefit the move could have provided for every other league franchise. The Athletics are already located within 15 miles of the Giants, and their potential 40 mile move to San Jose, California would not add a new team to the San Francisco Bay Area; rather, it would simply be a move of a current team to a different location within the metropolitan area. The refusal of the Giants or MLB to negotiate a potential compromise has kept the Oakland Athletics in a substandard facility and has led to their potential move to Fremont, CA – a less desirable location than San Jose. This paper investigates the legal, policy, and financial considerations concerning Major League Baseball’s territorial rules. Specifically, it addresses antitrust law as it pertains to American professional sport, relative sport franchise relocation cases, financial arguments why leagues desire to control relocation, financial components of MLB’s current Collective Bargaining Agreement, and the legal and financial impact of a challenge to MLB’s territorial rules – an option the Oakland Athletic initially investigated prior to their decision to pursue a potential move to Fremont.Antitrust law; Collective Bargaining Agreement; Franchise Relocation; Major League Baseball; Revenue Sharing; Territorial Rights

Where did National Hockey League Fans go During the 2004-2005 Lockout?: An Analysis of Economic Competition Between Leagues

Identifying and evaluating competitors is a critical aspect of operating a sport organisation. However, North American sports franchises have a limited understanding of competitors in their geographic market – particularly when calculating the degree of competition from other sport teams. Increasing the understanding of local sport competitors, whether in the same or different professional leagues, is critical not only to future franchise operations, but also for potential litigation concerning relevant product markets. This article utilises a natural experiment involving the National Hockey League’s (NHL) 2004-2005 lockout to assess the competitiveness of the NHL with the National Basketball Association (NBA) and four minor hockey leagues. On average, the five potential competitor leagues attained a 2% increase in demand, all else equal, during the lockout period. For the NBA this translates into more than US$1 million per team in increased incremental ticket revenue.relevant market; competition; demand; National Hockey League; regression

Transsulfuration pathway thiols and methylated arginines: the hunter community study

Background: Serum homocysteine, when studied singly, has been reported to be positively associated both with the endogenous nitric oxide synthase inhibitor asymmetric dimethylarginine [ADMA, via inhibition of dimethylarginine dimethylaminohydrolase (DDAH) activity] and with symmetric dimethylarginine (SDMA). We investigated combined associations between transsulfuration pathway thiols, including homocysteine, and serum ADMA and SDMA concentrations at population level. Methods: Data on clinical and demographic characteristics, medication exposure, C-reactive protein, serum ADMA and SDMA (LC-MS/MS), and thiols (homocysteine, cysteine, taurine, glutamylcysteine, total glutathione, and cysteinylglycine; capillary electrophoresis) were collected from a sample of the Hunter Community Study on human ageing [n = 498, median age (IQR) = 64 (60–70) years]. Results: Regression analysis showed that: a) age (P = 0.001), gender (P = 0.03), lower estimated glomerular filtration rate (eGFR, P = 0.08), body mass index (P = 0.008), treatment with beta-blockers (P = 0.03), homocysteine (P = 0.02), and glutamylcysteine (P = 0.003) were independently associated with higher ADMA concentrations; and b) age (P = 0.001), absence of diabetes (P = 0.001), lower body mass index (P = 0.01), lower eGFR (P&lt;0.001), cysteine (P = 0.007), and glutamylcysteine (P&lt;0.001) were independently associated with higher SDMA concentrations. No significant associations were observed between methylated arginines and either glutathione or taurine concentrations. Conclusions: After adjusting for clinical, demographic, biochemical, and pharmacological confounders the combined assessment of transsulfuration pathway thiols shows that glutamylcysteine has the strongest and positive independent associations with ADMA and SDMA. Whether this reflects a direct effect of glutamylcysteine on DDAH activity (for ADMA) and/or cationic amino acid transport requires further investigations.</br

Clinical and biochemical correlates of serum L-ergothioneine concentrations in community-dwelling middle-aged and older adults

Background: Despite the increasing interest towards the biological role of L-ergothioneine, little is known about the serum concentrations of this unusual aminothiol in older adults. We addressed this issue in a representative sample of communitydwelling middle-aged and older adults. Methods: Body mass index, estimated glomerular filtration rate, serum concentrations of L-ergothioneine, taurine, homocysteine, cysteine, glutathione, cysteinylglycine, and glutamylcysteine were evaluated in 439 subjects (age 55–85 years) randomly selected from the Hunter Community Study. Results: Median L-ergothioneine concentration in the entire cohort was 1.01 IQR 0.78–1.33 mmol/L. Concentrations were not affected by gender (P = 0.41) or by presence of chronic medical conditions (P = 0.15). By considering only healthy subjects, we defined a reference interval for L-ergothioneine serum concentrations from 0.36 (90% CI 0.31–0.44) to 3.08 (90% CI 2.45–3.76) mmol/L. Using stepwise multiple linear regression analysis L-ergothioneine was negatively correlated with age (rpartial =20.15; P = 0.0018) and with glutamylcysteine concentrations (rpartial =20.13; P = 0.0063). Conclusions: A thorough analysis of serum L-ergothioneine concentrations was performed in a large group of communitydwelling middle-aged and older adults. Reference intervals were established. Age and glutamylcysteine were independently negatively associated with L-ergothioneine serum concentration.</br
