Road traffic crashes managed by Rescue 1122 in Lahore,Pakistan

The objective of this retrospective study was to describe demographic characteristics, injury patterns and causes of road traffic crashes (RTCs) managed by Rescue 1122 in Lahore, Pakistan during the period 2005–2010. In total 123,268 RTCs were reported and responded by Rescue 1122 ambulance service during the study period. Of the 132,504 victims of RTCs, there were 67% male and 33% female subjects, and the maximum share (65%) was reported among people aged 16–35 years. Motorcyclists were involved in 45% of crashes, with over-speeding (40%) found to be the major reason of these collisions. Similarly, minor injuries (65%) and fractures (25%) were the most reported outcome of these crashes. It is concluded that data from ambulance services, if appropriately collected, can provide valuable epidemiological information to monitor RTCs in developing countries. However, in Pakistan, the collection of data as well as the registration process needs further improvement.     

Pillion riders' cloth related injuries and helmet wearing patterns: a study of Lahore,Pakistan

This study aims at investigating the burden and pattern of clothing related pillion riders' injuries and their helmet wearing pattern in Lahore, Pakistan. Data were collected for nine months (July 2013 to March 2014), reporting 13,248 motorcycle related injuries, out of which 8751 (66%) cases were related to the clothing related pillion riders' injuries. Out of these injuries 10.30% were severe injuries which can be prevented or reduced by proper safety measure, e.g. wearing helmet. It was also found that most of the fatalities were not wearing helmet. Injuries due to wearing of loose fitting clothes and absence of helmet are not uncommon in Pakistan and other underdeveloped parts of the world. Such accidents may be reduced by creating awareness and safety sense in the riders, where use of safe dress and helmet should be encouraged in order to avoid such fatal damages.     

Wasted Positive Intentions: The Role of Affection and Abundance on Household Food Waste

This qualitative study, grounded theory oriented, identifies familial affection and preference for abundance as major drivers of wasted food in lower-middle income American families. These positive intentions provide an improved understanding of household food waste, a problem with high environmental impact and moral implications. Based on empirical data collected with twenty caregivers via in-depth interviews, observations, and analysis of photos, this study provides novel explanations, such as on how stockpiling comfort foods in abundance – a form of both boosting positive self-emotions and showing affection for kids – can promote more wasted food. Other antecedents identified include multiplicity of choices, convenience, procrastination and unplanned routines. In sum, this research identifies a negative outcome of affection and food abundance in the family context, while providing a theoretically relevant general framework to help understand the food waste phenomenon. Authors suggest increasing the awareness of nutritional gatekeepers through behavioral economics principles.     

Identifying the factors behind fatal and non-fatal road crashes: a case study of Lahore,Pakistan

ABSTRACT

The study identifies the factors behind fatal and non-fatal road crashes in Lahore, Pakistan, by investigating 461 reported cases to Traffic Police Lahore that occurred during January–November 2014. Road crashes are categorized into fatal and non-fatal crashes and, because of the binary nature of the dependent variable, logistic regression is used to identify the factors behind these crashes. As a follow-up, discriminant analysis is employed to classify the factors related to fatal and non-fatal crashes. The logistic regression results reveal that females are at higher risk of fatalities than male drivers. Among vehicle types, rickshaws and cars are more involved in fatal accidents because both are growing at large on roads. Long trucks and trailers are also involved in fatal accidents, mainly because of their huge size and drivers’ risky driving behaviours. It is also noted that risk of fatalities is higher in case where two vehicles bumped each other. Speeding and overloading are the common behaviours resulting in fatal crashes. Better urban transport systems and strict compliance with traffic rules and regulations may improve road safety in Pakistan.     

Creating Value for Customers,Clients, Partners and Society: An Introduction to the Special Issue on Food Waste

ABSTRACT

Roughly one-third of edible food produced in the world is wasted, that is, it is never consumed by humans, despite the persistent demands for nutrition throughout the world. The American Marketing Association defines marketing as “…the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging offerings that have value for customers, clients, partners, and society at large.” When it comes to food, an increasing number of these key stakeholders question how a global marketing system that routinely wastes a startling fraction of its product comports with “…value for customers, clients, partners, and society at large,” and whether the food marketing system can do more to sustainably convert scarce planetary resources into global nutrition. We introduce the articles in this special issue, which provide an intellectual and empirical basis for exploring how the global marketing system generates a substantial amount of food waste and how the food marketing system can do more to reduce the amount of wasted food.     

A Study of Factors Influencing Parental Patronage of Quick Service Restaurants

Summary

This study identified factors influencing parental quick service restaurant patronage. Results indicated that parents are influenced to patronize quick service restaurants most often by speed of service, menus that offered their childrens' favorite food items, and parents' lack of time for meal preparation at home. Children preferred French fries, pizza, hamburgers, cheeseburgers, and chicken nuggets at quick service restaurants. French fries, the favorite childrens' fast food menu selection, was ranked by respondents as one of the least healthy food items, while mashed potatoes, one of childrens' least favorite fast food menu selections, was perceived to be one of the healthier food selections by parents. Restaurateurs were encouraged to develop newer, healthier methods of preparing these popular menu items while offering more nutritious menu selections for children.     

What a Waste! A Study of Food Wastage Behavior in Singapore

This study focuses on analyzing food wastage behavior of consumers in Singapore. Qualitative research with experts from food waste management organizations and restaurant operators indicated key reasons for food wastage to be food spoilage, risk of hurting brand due to substandard food, lack of appropriate methods for sorting food, reverse logistics for proper waste collection/disposal, and appropriate recycling facilities. High costs of waste disposal, lack of government incentives or regulations governing service providers, and lack of awareness among consumers also contributed to solid food waste in Singapore. A survey with consumers recorded their habits with regard to planning food purchases, food wastage while cooking, and wastage during consumption of cooked, canned, and ready-to-eat products. A stepwise multiple discriminant analysis done on a key categorical variable “How much effort do you take to minimize amount of uneaten food you throw away?” yielded two groups that differed significantly along several attitudinal/behavioral dimensions.     

Food waste in the retail sector: A survey-based evidence from Central and Eastern Europe

This paper explores the issue of food waste in the Lithuanian retail sector. A questionnaire survey was designed in order to collect the relevant data from both the largest retail chains with stores around the country and companies with small-scale stores in rural areas. The present case is interesting as the literature on Central and Eastern European countries is scarce in the sense of the quantification of food waste. In this paper, the amounts of food waste among different food product categories are discussed and then extrapolated to approximate food waste in retail trade for Lithuania by using sales revenue as a key parameter. The results suggest that food waste in the Lithuanian retail sector amounts to 36.4 thousand tonnes or 13.0 kg per capita per year. Fruits and vegetables account for more than a half (63%), whereas meat (products) come next representing some 9% of food waste. Therefore, these products can be considered as the major targets for valorisation schemes and other measures aimed at mitigation of food waste.

The Impact of Eco-Design Packaging on Food Waste Avoidance: A Conceptual Framework

Abstract

Eco-design packaging is a potential tool to reduce food waste. However, the absence of a theoretical basis regarding the relationships between eco-design packaging and consumer food waste behavior obscures the social impact of this packaging. This study assesses research linking eco-design packaging and food waste avoidance from a consumer perspective. The authors analyze 22 articles in top-tier journals, and conclude that consumer perceptions of eco-design packaging could reduce food waste. Results lead to a conceptual model of the mechanism whereby consumer perceptions of eco-design packaging influence food waste avoidance intentions.     

Restaurants and the Bring-Your-Own-Bottle of Wine Paradox: Involvement Influences,Consumption Occasions,and Risk Perception

The current study focuses on differences between high- and low-involvement consumers in terms of the bring-your-own-bottle of wine phenomenon, influence of consumption occasion(s), and how bring-your-own-bottle is used by consumers as purchase risk-reduction strategy. Results show that level of wine involvement determines the importance of bring-your-own-bottle of wine. The consumption situation in which bring-your-own-bottle of wine might occur is a main factor when buying wine. Bring-your-own-bottle of wine is largely the result of risk-reduction strategies where high-involvement wine consumers are more susceptible to perceived risk in the full-service casual restaurant sector and reduce this risk through bring-your-own-bottle.

Seeing Is Not Believing: Perceptions of Date Labels over Food and Attributes

ABSTRACT

This study investigates consumers’ perceptions of date labels (“Best by” and “Use by”) between different food items (spaghetti sauce and deli meat) and across different attributes (nutrition, quality, safety, and taste). We collected data from experimental auctions and a survey held in cities located in two different regions of the United States. Previous research suggests that confusion over date labels contributes to waste. Thus, we ask respondents to indicate the meaning of date labels for products over attributes. Overall we find that respondents have differing conceptions of date labels by product and over attributes, which reflects confusion over the date labels. However, the differences, while statistically significant, are not large enough to suggest a reversal of perception from agreement to disagreement in the meaning of the date label for specific attributes. The findings question the effectiveness of a two-date label regime to reduce food waste.     

Big social data and customer decision making in vegetarian restaurants: A combined machine learning method

Customers increasingly use various social media to share their opinion about restaurants service quality. Big data collected from social media provides a data platform to improve the service quality of restaurants through customers' online reviews, where online reviews are a trustworthy and reliable source that helps consumers to evaluate food quality. Developing methods for effective evaluation of customer-generated reviews of restaurant services is important. This study develops a new method through effective learning techniques for customer segmentation and their preferences prediction in vegetarian friendly restaurants. The method is developed through text mining (Latent Dirichlet Allocation), cluster analysis (Self Organizing Map) and predictive learning technique (Classification and Regression Trees) to reveal the customer’ satisfaction levels from the service quality in vegetarian friendly restaurants. Based on the obtained results of our experiments on the data vegetarian friendly restaurants in Bangkok, the models constructed by Classification and Regression Trees were able to give an accurate prediction of customers' preferences on the basis of restaurants' quality factors. The results showed that customers’ online reviews analysis can be an effective way for customers segmentation to predict their preferences and help the restaurant managers to set priority instructions for service quality improvements.     

食品质量安全供应链规制研究:以乳品为例

在现有的质量规制政策下,食品质量安全事故频繁发生的原因是强制性公共规制难以有效地介入食品供应链的质量生产过程。对供应链生产过程的公共规制失灵,为被规制者以质量手段谋求利益最大化留下了充分的对策性空间。由供应链核心厂商实施的私人质量规制,以其信息成本优势、对策性行为少和规制的可持续性,能够有效地弥补公共规制对供应链的质量规制空白。     

我国自闭症儿童现状调查研究——以上海地区为例

自闭症是一种广泛性发育障碍。目前,我国自闭症儿童的数量呈逐年增加的趋势,但国家在这方面的立法保障缺失,教育及康复培训资源匮乏。而对于成年自闭症患者,其生活保障完全由家庭承担。以上海地区为例,用调查问卷的形式,向社会群众调查了对于自闭症儿童的看法。得出结论:目前普通大众对于自闭症儿童了解较少,甚至对自闭症儿童产生了误解。有关部门相关政策设立不到位,自闭症儿童需要社会各界和政府部门的帮助支持。

Two-Stage Determinants of the Organic Food Retailing Landscape: The Case of Manhattan,New York

Retail sales of organic food products have been increasing faster than any other category of food and have penetrated mainstream retail grocery outlets. The majority of the literature on organic markets explores the socioeconomic characteristics of consumers, linking these traits to the probability of buying organic food, and it suggests that access to organic food is an important but overlooked factor in such studies. More recently, research focusing on food retailer marketing strategies for organic food finds that traditional strategies such as price promotions are largely unsuccessful with increasing sales for the organic food consumer. This article focuses on the retailer decision to offer organic food for sale. We model the decision as a two-stage process, where the retailer’s first decision is whether to sell organic food, and the second decision determines how many different organic products to offer for sale. In doing so, by using data collected in stores, we assess the organic food retail landscape in Manhattan, NY. We find that the decision to offer organic food for sale depends on the neighborhood socioeconomic characteristics, and the amount of organic food offered for sale depends on the size of the store.

A Study of Factors Affecting Tip Size in Restaurants

Abstract

This study was undertaken to gain understanding of the tipping phenomenon in restaurants. The study reviews the phenomenon of tipping and the accompanying characteristics that determine the gratuity amount of consumers. An understanding of the relationship between tip size and factors such as food quality and level of service will help to determine what areas restaurant personnel should focus on to enhance customer satisfaction and facilitate those working in the restaurant industry. In this study, the researchers tested the hypothesis that the greater the tip size, the more satisfied the customer is with the food quality and service provided by server. The other hypothesis tested was: The greater the tip size, the greater the likelihood of a return patronage. Data were collected at a restaurant in Houston, Texas. This analysis found a strong relationship between tip size and service provided by server and return intentions, but did not find a significant relationship between tip size and food quality.
