E-commerce’s Impact on Big-Box Retailers

The history of retail has been an evolutionary process of new innovations and transformations. Previous changes include: the development of catalogue based retail, and the recent innovation of super stores, known as big-box retailers. It is possible that we are dawning upon a new revolution of the retail environment as electronic commerce (e-commerce) continues to grow. This paper will analyze the impact of e-commerce on retail markets, specifically big-box stores (warehouse style retailers with over 750 million in sales). Using financial and real estate data from BloombergTM, and e-commerce data from eMarketerTM and the US Census Bureau two models were built. These two models will be utilized to answer the following questions. Has the growth of e-commerce affected the retail real estate market and the retail financial market? Which retail submarkets have been affected most by the growth of e-commerce? The first model will test whether growth in e-commerce spending in retail submarkets (i.e. sporting goods and bookstores) will cause a decrease in the stock performance of big-box retailers within those market sectors. The second model will test whether growth in the different e-commerce retail submarkets will cause a decrease in the square footage growth rate of the big-box stores in those same retail submarkets

A workshop assessing the effects of social support on the incidence of burnout

Thesis (M.A.) University of Alaska Fairbanks, 2002This research was designed to address the issue of burnout by developing and presenting a workshop to 26 human service providers (primarily educated Caucasian women) to increase their level of social support and address organizational concerns. Two measures were used in a pre-posttest design: the Maslach Burnout Inventory and social support questionnaire developed for this study. The results showed that burnout dropped significantly on the emotional exhaustion subscale. There was a drop in the depersonalization subscale but it only approached significance. There was also a negative correlation of perceived social support satisfaction with emotional exhaustion and depersonalization at both pre and posttest. Building social support has implications for reducing burnout. Studies with quasi-experimental designs and larger samples are needed to further validate the findings of this study

A creel survey of the Tellico and North Rivers : comparisons between a stocked and a wild trout stream in Tennessee

The Tellico and North Rivers, located in Tennessee\u27s Cherokee National Forest, represent a heavily stocked trout stream with wild rainbow (Oncorhynchus mykiss), and brown trout (Salmo trutta) present, and a purely wild trout stream. Tellico River receives between 60,000 and 100,000 catchable rainbow trout from late March to early September of each year. It is open for fishing under general Tennessee trout regulations. The North River has received no stocked trout of catchable size in the last decade. It is open for fishing under special trout regulations. This study was implemented to compare pressure, catch, harvest, fishing methods, and distance traveled between the two rivers, and determine the return to creel for stocked trout. A roving creel survey of both rivers was conducted during the 1995 and 1996 stocking seasons. Sample areas of 6.44 kilometers (km) in length were selected for each river. There were 1036 angler interviews conducted over 59 creel periods for the Tellico River, and 154 angler interviews conducted over 62 creel periods for the North River. Within the Tellico River sample area, fishermen averaged 28,824 angler-hours per season. North River fishermen averaged 3,168 angler-hours. Tellico anglers caught 20,299 stocked trout, and 15,355 wild trout per season. North anglers caught 4,658 wild trout per season. The release rate was 95% for Tellico River wild trout, 8% for stocked trout, and 96% for North River wild trout. Catch per unit effort was 1.24 for the Tellico, 1.47 for the North. Widely varying fishing methods were used on the two rivers. Harvested wild trout for the Tellico River sample area average 768, and accounted for a 12% harvest induced mortality of wild trout greater than 90 millimeters in length. Total angler induced mortality for Tellico River wild trout greater than 90 mm is estimated to be from 12 to 20%. The 186 wild trout harvested from North River accounted for a 5% harvest induced mortality of wild trout greater than 90 mm. Total angler induced mortality for North River wild trout greater than 90 mm is estimated to be from 5 to 10%. Tellico River anglers harvested 18,675 of 19,591 stocked trout per season from the sample area for a 95% return rate. Monroe county anglers were the most numerous, with local anglers (those having traveled 80 km or less) accounting for 40% of all fishermen on both rivers. Less than 15% of anglers on either river were non-residents of Tennessee

Impact of a community-based diabetes self-management program on key metabolic parameters

OBJECTIVE: Characterize the impact of a pharmacist-led diabetes self-management program on three key metabolic parameters: glycosylated hemoglobin (HbA1c), low-density lipoprotein cholesterol (LDL-C), and mean arterial blood pressure (MAP) among employee health program participants. METHODS: A self-insured company in the Kansas City metropolitan area began offering a pharmacist-led diabetes self-management program to eligible company employees and their dependents in 2008. A retrospective pre-post analysis was conducted to determine if the program affected key metabolic parameters in participants by determining mean change after one year of participation. RESULTS: Among 183 program participants, 65 participants met inclusion criteria. All three key metabolic parameters were significantly reduced from baseline to one year of program participation: HbA1c decreased from 8.1% to 7.3% (p=0.007); LDL-C decreased from 108.3 mg/dL to 96.4 mg/dL (p=0.009); and MAP decreased from 96.1 to 92.3 mm Hg (p=0.005). CONCLUSIONS: The pharmacist-led diabetes self-management program demonstrated significant reductions in HbA1c, LDL-C, and MAP from baseline to one year of program participation. Improvements were statistically significant and clinically relevant for each parameter. Previous studies indicate these reductions may cause reduced overall healthcare costs

When select committees speak, do newspapers listen?

It is frequently claimed that the House of Commons’ select committees have grown in prominence since key reforms were implemented in 2010. Brian J. Gaines, Mark Goodwin, Stephen Holden Bates and Gisela Sin test this claim specifically in relation to press coverage. They find a pattern of increased newspaper attention after the reforms, but caution that these results show no consistent sustained increase, and also vary considerably depending on committee

Growth and Feed Efficiency of Juvenile Channel Catfish Reared at Different Water Temperatures and Fed Diets Containing Various Levels of Fish Meal

Channel catfish Ictalurus punctatus do not feed well at low temperatures. It is generally thought that a diet containing fish meal enhances feed palatability at low temperatures since fish meal is highly palatable to fish. There is a lack of information on the effects of fish meal levels on the growth performance of channel catfish reared at low temperatures. Therefore, a study was conducted in a recirculating system to examine the effects of fish meal levels on the feed consumption, weight gain, and feed efficiency of juvenile channel catfish reared at various temperatures. Fish with an initial weight of 9.6 ± 0.1 g were stocked in 23-L clear polycarbonate tanks maintained at approximately 17, 21, or 27 °C. The fish were fed with diets containing 0, 4, or 8% menhaden Brevoortia spp. fish meal for 9 weeks. There was a significant interaction between water temperature and fish meal level with respect to weight gain. At 27 °C, fish fed diets containing 4% and 8% fish meal gained significantly more weight than fish fed the all-plantprotein diet. However, the level of fish meal had no significant effect on the weight gain of fish at 17 °C or 21 °C. This suggests that the olfactory and gustatory responses of channel catfish to fish meal (up to 8% in the diet) may not be as sensitive at low temperatures as at optimum temperatures. The results also indicate that more than 4% fish meal in the diet is not beneficial for the optimum growth and feed efficiency of channel catfish fingerlings raised at 27 °C
