The algorithm given on page 6 may deadlock because communications do not follow the directedness of the tree but may occur in either direction. The algorithm, and its proof, are correct if we restrict ourselves to trees, rather than RDAG`s. RDAG's ((1]) do not contain directed cycles, but may contain cycles. In those cases the algorithm, and the 'proof' of the absence of deadlock on p.7 are inc...

Purpose: The purpose of the paper is to identify store format attributes that impact on store format choice when consumers conduct fill-in or major trips to buy groceries. By doing so, we take into consideration that consumers patronise multiple (store-based) formats depending on the shopping situation operationalised by the type of shopping trip. Design/methodology/approach: The paper adopts t...

Although seafood is considered to be a healthy food choice, the recommended consumption level of two servings per week is still not reached in most countries. Previous research has identified potential barriers of seafood consumption, including purchase and consumption convenience, but it is still unclear to what degree consumer choice is affected by convenience relative to known choice drivers...

The urbanized region ofJing(Beijing)Jin(Tianjin)-Ji (alias of Hebei province) and its nearby surrounding region (3JNS) is becoming China’s most polluted area by haze, exceeding even the Yangtze and Pearl river deltas. Aside from pollutant emission, the meteorology of the planetary boundary layer (PBL) is the most important factor affecting haze pollution. Focusing on July 2008, the aerosol opti...

In-store measures were utilized to evaluate the availability of healthy food choices and nutrition/health promotion messages for cancer risk reduction in the selected Alabama Black Belt counties/cities. Sixty one retail food outlets (RFOs) were audited in 12 Alabama Black Belt cities. Store types included convenience stores (49.2%), restaurants (19.7%), fast food restaurants (16.4%), small supe...

Numerical results that demonstrate how ion emissive surfaces should be shaped to induce the formation of well-focused, high-current beamlets are presented. Results obtained when the sheath shape and position are established and then held constant as operating conditions are changed are compared to corresponding results obtained with a conventional plasma sheath that moves. These comparisons sho...

This study aims to determine the effect of perceived convenience and online customer reviews on consumer buying interest in sociolla store. Primary data obtained from this were used collection techniques. To approach problem, theory Kotler Keller, 2016 states that factors influence are perception convenience. The method is by using survey method. research quantitative methods with analysis tech...

Most models of consumer purchase process that are used in operations focus on purchases from a single channel, typically the offline brick-and-mortar store [3]. However, there has been a proliferation of multiple retail channels, such as online and mobile. This proliferation has created the need for operational decisions to model consumer switching between different channels during the purchase...
