PurposeExperienced reviewers in general can produce high-quality product reviews, and thereby get more helpful votes. This paper explores the question that whether the depth and width of the reviewers' experience distribution have effects on the helpfulness of their reviews.Design/methodology/approachAdopting the restaurant review data from Yelp, the present paper classifies the restaurants in to different categories applying the Word2Vec technique, such as Asian or fast food. By evaluating the number of a user's historical reviews in a specific category, and the evenness of such distribution in different categories, the experience specialty and experience diversity are defined respectively.FindingsThe analysis shows that users specialised in a given category can produce more helpful reviews in that category. The users with diverse historical experience, i.e. have posted reviews for many categories, also can produce helpful reviews. In addition, the experience diversity shows a positive moderation effect on the influence of experience specialty. Thus, users with diverse experience while specialized in a particular category are the source of most helpful reviews.Originality/valueWhile previous studies mostly consider the raw number of historical reviews as a reviewer's experience, we distinguish such experience by product category and focus on the width and depth of its distribution. The results not only shed lights on the mining of high-quality reviews and reviewers but also provide insights on the management of online review platforms and electronic marketing.

PurposeThe purpose of this paper is to explore the impact of product information on impulse purchases in a cross-border electronic commerce (CBEC) setting from the perspective of cue stimulation.Design/methodology/approachThis study proposes a research model of impulse purchases in CBEC based on the cue utilization theory and Stimulus-Organism-Response (S-O-R) model. The research model was tested using covariance-based structural equation modelling. Data were collected from the consumers of a popular CBEC platform in China.FindingsA high-quality product description has a significant positive effect on concentration but not on curiosity and autotelic experience. A high-quality product display has a significant positive effect on concentration, curiosity and autotelic experience. High-quality product content has a significant positive effect on curiosity and autotelic experience but not on concentration. Curiosity and autotelic experience both have a significant positive effect on impulse purchases; however, concentration has no such effect on an impulse purchase. Curiosity and autotelic experience have a full mediation effect between product display and impulse purchases and between product content and impulse purchases, respectively.Originality/valueThis study integrates the S-O-R model and cue utilization theory to construct a theoretical model of product information-flow experience-impulse purchases. According to the model, we can understand how product information influences consumers' impulse purchases in CBEC.

SummaryTwo cases of livestock production involving French local breeds are analysed. The first shows how a high quality product under AOC (Protected Designation of Origin — PDO) has been defined for the Bresse chicken breed, formely kept by fancy breeders. The second shows the role of the local cattle breeds Abondance and Tarentaise in both the use of mountain areas and the development of PDO products. How to consider such values in a public policy dealing with farm animal genetic resources is discussed.

Abstract The presence of stems in cut tobacco is detrimental to cigarette quality, resulting in problems during production particularly on today's high-speed makers. Incomplete threshing and the use of unthreshed semi-Oriental tobaccos can increase the stem content in the cut tobacco considerably. The percentage of stems present in cut tobacco was investigated by HauniMaschinenbau AG specifically for semi-Oriental tobacco. Their findings show that not all stems present in the strips or lamina after cutting are classified as “objectionable”. However, the percentage of objectionable stems in the cut tobacco is not inconsiderable and depends on the thickness of the stems present. Reducing the objectionable stem contingent in cut tobacco is therefore a crucial concern of many cigarette manufacturers who set great store on ensuring high-quality product. HauniMaschinenbau AG offers a cut tobacco separator which has been specially designed for this purpose and also used as a cooler. A corresponding model is available in the HauniMaschinenbau AG pilot plant in Hamburg for tests using the customers’ own tobacco.

The results of the study of the influence of various concentrations of the complex bakery improver «Unipan Total» on the properties of semi-finished products and quality indicators of bakery products are presented. Bakery products were produced using the unpaired method according to a unified recipe for Dniprovskaya buns. To obtain a high-quality product, prototypes were prepared from wheat bakery flour of the highest grade with the addition of the «Unipan Total» improver at a concentration of 0,5 to 8% to the flour weight, control ones without the improver. Organoleptic and physicochemical indicators of the quality of wheat bread samples were determined by conventional methods.

Buyers on eBay commonly rely on seller feedback ratings to determine bidding strategies.  Various studies have examined the impact of eBay’s reputation system on auction outcomes.  This study builds on prior research by examining the relationship between seller ratings on auction prices for two distinct product types, DVDs and designer watches and by benchmarking the bid prices against retail prices. The results show that eBay ratings explain a greater degree of price variation in Designer Watches than in DVDs.  The study also suggests that high quality product listings with such features as digital images, formatted pages, and product details may result in higher bid prices.

The aim of this investigation was to develop a treatment for combined porcine blood corpuscle concentrate (BCC) and porcine collagenous connective tissue (rind) so as to make more use of these slaughter by-products as an ingredient in a high-quality product such as salami-type sausage. For this study, BCC was preserved, standardized (sBCC) (15% NaCl and 25% protein content), and then added (proportion of sBCC to rind, 15:85) to rind subjected to different treatments designated A, B, and C (A, 2 h at 90°C; B, 5 min at 90°C; and C, 2 h at 3°C). One half of each mixture was again heated (designated A1, B1, and C1; F70, ∼15), and the other half was only cooled (designated A2, B2, and C2). The now colored, highly proteinaceous rind mixtures (A1 to C2) were then cooled and granulated (designated GBR-A1 to GBR-C2). Three of the granulates (GBRA1, -B1, and -B2) proved to be promising new raw materials: their aerobic plate counts were <log 4.0 CFU/g, and their color was appealing (L* values, 23.9 to 25.9; a* values, 17.7 to 22.2; b* values, 11.5 to 12.7). These granulates were then substituted for part (5%) of the meat in the production of fermented raw salami-type sausages. Two of the sausages (SA1 and SB1) were microbiologically stable (containing mainly lactobacilli) and had positive sensory, chemical, and physical properties (e.g., protein, 21%; water activity, 0.90; pH, between 5.3 and 5.4 on day 36) meeting all standards for commercially produced raw sausages. Our investigation yielded a practicable way to treat and combine two slaughter by-products for use in a high-quality meat product.

In a principal-agent framework under moral hazard, when the monopolist can pass on the liability of any defect of the product to the subcontractors, and cannot credibly commit to a high level of investment, he actually chooses a low investment level and supplies a low quality product if the product replacement cost is below a critical level. However, under contract renegotiation, when the monopolist is taking the entire risk of replacing the defective product, he will profitably choose high investment level and serves high quality product. But the results show that the monopolist will choose to renegotiate the contract only for limited values of product replacement cost, even if renegotiation is socially optimal.

The European Union (EU) has some of the strictest standards for mycotoxins in food and feed in the world. This paper explores the economic impacts of these standards on other nations that attempt to export foods that are susceptible to one mycotoxin, aflatoxin, to the EU. The current EU standard for total aflatoxins in food is 4 ng/g in food other than peanuts, and 15 ng/g in peanuts. Under certain conditions, export markets may actually benefit from the strict EU standard. These conditions include a consistently high-quality product, and a global scene that allows market shifts. Even lower-quality export markets can benefit from the strict EU standard, primarily by technology forcing. However, if the above conditions are not met, export markets suffer from the strict EU standard. Two case studies are presented to illustrate these two different scenarios: the U.S. pistachio and almond industries. Importantly, within the EU, food processors may suffer as well from the strict aflatoxin standard. EU policymakers should consider these more nuanced economic impacts when developing mycotoxin standards for food and feed.
