CONVENIENCE STORE PRACTICES AND PROGRESS WITH EFFICIENT CONSUMER RESPONSE: THE MINNESOTA CASE
The adoption of Efficient Consumer Response (ECR) practices by Minnesota convenience store (C- store) is explained in this study. Data were collected through a mail survey distributed to more than 250 Minnesota C-stores ranging in size from single, independently owned stores to over 100 store chains. The survey instrument was developed to collect data on the following components important to C-store operations and the implementation of ECR: information systems, ordering, receiving, inventory management, and pricing practices. Findings are presented from three distinct perspectives: 1. Location: Rural C-stores, which often meet customer needs that were once met by small supermarkets, carried a wider range of products and offered more services than C-stores in urban and suburban locations. However, rural stores had the lowest adoption rate for practices related to the ECR initiative. Urban chains coordinated business practices with suppliers to a greater degree than suburban and rural chains. 2. Chain size: Larger chains were more likely to have implemented the more costly technological practices than were small chains. This was expected since large chains can spread the fixed costs of ECR adoption over a larger number of stores. Larger chains also cooperated and communicated more with their suppliers than small chains. Again, this was expected, since larger chains can economize on transaction costs involved in maintaining these business relationships. 3. ECR practices: ECR adoption and superior performance were positively related. Having adopted six to nine practices was positively correlated with higher inside and outside sales per square foot of selling area and higher annual inventory turns. However, it was not clear whether there was a causal relationship in either direction between ECR practices and store performance. The C-store industry is changing, as new information technologies, new business practices, and new retail strategies are developed. The results from this survey can serve as a baseline for future research monitoring the adoption of these innovations and assessing their impact on productivity and profitability. Minnesota C-Stores appear to be smaller but more productive than the national average. Overall, it appears ECR is just beginning to impact the Minnesota C-store industry. Nonetheless, regression analyses confirmed ECR practices are positively related to store sales performance and those stores adopting the most practices had higher productivity measures.Industrial Organization, Marketing,

A FACTOR ANALYSIS OF SUPERMARKET MANAGEMENT PRACTICES
Empirically based management practice indices are constructed using results from factor analysis of data from 344 stores in the 2000 Supermarket Panel. These indices are compared to six management indices based on expert opinion. The empirical indices group variables differently and provide a more compact summary of supermarket management practices.Agribusiness,
THE 2001 SUPERMARKET PANEL ANNUAL REPORT
The Supermarket Panel collects data annually from individual supermarkets on store characteristics, operations, and performance. It was established in 1998 by the Food Industry Center as the basis for ongoing study of the supermarket industry. The Panel is unique because the unit of analysis is the individual store and the same stores are tracked over time. This makes it possible to analyze the processes by which new technologies, business practices, and competitive forces are changing the industry. The 2001 Supermarket Panel consists of 563 stores selected at random from the nearly 32,000 supermarkets in the U.S. or invited to participate through their affiliation with IGA. These 563 stores are located in forty-seven states and the District of Columbia. They are a representative cross section of the industry, including stores from all formats that belong to ownership groups ranging from single stores to the country's largest chains.Agribusiness, Industrial Organization, Marketing,
THE 2002 SUPERMARKET PANEL ANNUAL REPORT
The Supermarket Panel collects data annually from individual supermarkets on store characteristics, operations, and performance. It was established in 1998 by the Food Industry Center as the basis for ongoing study of the supermarket industry. The Panel is unique because the unit of analysis is the individual store and the same stores are tracked over time. This makes it possible to analyze the processes by which new technologies, business practices, and competitive forces are changing the industry. The 2002 Supermarket Panel consists of 866 stores selected at random from the nearly 32,000 supermarkets in the U.S. or invited to participate through their affiliation with cooperating retail companies or IGA. These 866 stores are located in forty-nine states. They are a representative cross section of the industry, including stores from all formats that belong to ownership groups ranging from single stores to the countrys largest chains.Industrial Organization, Marketing,

Savings Clauses and Trends in Natural Resources Federalism
This article considers recent trends in federalism, with particular attention to natural resource law\u27s statutory savings clauses. It begins with a case study of elk management in Jackson Hole, Wyoming. The elk controversy shows how a statutory savings clause can provide a state with traction to advance its interests, and demonstrates how the political winds of change can shift the balance of state-federal relations. The article then focuses on the common statutory savings clauses and their roles in circumscribing federal agency authority and establishing a basis for cooperation between federal and state governments. We analyze the interpretive approaches the judiciary may employ to make sense of the statutory savings language, and conceptualize them along a continuum of influence in resolving cases. The article concludes with an explanation of trends that set the direction for policy innovations in natural resources federalism and general thoughts about the future of federalism in natural resources law
Relationship between structure and function of neurons in the rat rostral nucleus tractus solitarii
To investigate the relationship between the structure and function of neurons in the rostral (gustatory) nucleus tractus solitarii (rNTS), we analyzed the morphological and biophysical properties of rNTS neurons by performing whole-cell recordings in a brain slice preparation. Overall, neurons (n=58) had a mean somal diameter of 16 Μm, an average dendritic length of 598 Μm, an average dendritic thickness of 0.91 Μm, and a spine density of 0.037 spines/Μm. Neurons were separated into three groups (elongate, miltipolar, and ovoid) on the basis of previously established morphological criteria. The highest percentage (49%) of neurons were classified as ovoid, while 35% were multipolar and only 16% were elongate. The most frequently ovserved firing pattern, in all three cell types, elicited by a 1,200 ms, 100 pA depolarizing current pulse was a regularly firing spike train. However, the intrinsic firing properties of the remaining neurons were different. Thirty-one percent of the ovoid neurons responded with a short burst of action potentials and 44% of the elongate neurons showed a delay in the onset of the spike train following a hyperpolarizing prepulse. Less than 16% of the multipolar neurons demonstrated either of these firing characteristics. Therefore, rNTS neurons with similar morphology do not have unique biophysical properties. However, the data suggest that there may be subpopulations of the three morphological types, each of which displays a different firing pattern. Since the structure and function of the three morphological groups were not strictly correlated, these subpopulations may represent functional groups. © 1994 Wiley-Liss, Inc.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/50061/1/903440105_ftp.pd
