Forces exerted by jumping children: a pilot study

Abstract

This article reports on a pilot study of the loads exerted vertically by children when jumping. The subjects of the study were 17 children, aged from two to twelve years. Measurements were made using video recordings and a force-plate. The influence of the stiffness of the base and of jumping with and without shoes was investigated. Knee flexion, push-off force (thrust) and the ratio between push-off force and body weight (relative thrust) were analyzed. Measurements of the knee flexion showed a certain consistency for each child. The angle of knee flexion during push-off follows a bimodal distribution with maxima at 60^° and 90^°. The results for relative thrust suggest a close relationship between push-off force and body weight.     

Dishwasher-related injuries: survey and literature review

Domestic injuries are quite common among children aged 0–4 years old. Hazards lurking in the kitchen area can cause serious injuries in children. Through this study, we aim to raise public awareness of the potential and underreported risk of injuries related to dishwashers. Anonymous questionnaires consisting of 12 questions were distributed to adult females with children under 5 years old, including nurses, secretarial staff and outpatients. Commonly used dishwashers were surveyed by visiting high-street stores, and each brand's user manual was studied. A literature search using Medline and Pubmed was conducted for examining reported dishwasher-related sharp injuries. Forty households filled out survey questionnaires. Their responses indicated that 10% and 12.5% of children participate in unloading or loading dishwashers, respectively. Results showed that the incidence of related injuries was 12.5% among adults and 5% among children, and young children are at risk of sharp injuries in households with dishwashers. The dangerous loading and unloading of sharp objects and the direct involvement of toddlers should be discouraged, with the help of manufacturers.     

The epidemiology of swimming pool injuries in The Netherlands

Objective: To study the frequency and distribution of swimming pool injuries in The Netherlands. Data and methods: We used data of the Dutch Injury Surveillance System, which collects national data on patients treated in a hospital emergency department anywhere in The Netherlands. This system is based on a sample of 16 hospitals, which is representative for the whole country. With the help of pooled data for the years 1995 and 1996, we estimated the annual frequency of swimming pool injuries treated in a hospital emergency department. We made a comparison with the epidemiology of sports injuries with respect to the observed distribution by age, gender, type of injury and injury severity. Results: The average annual number of people seeking treatment at an emergency department after a swimming pool accident is small compared with the average annual number of sports injuries. Almost half of the swimming pool injuries (45%) concern 5–14 year-old children, a much higher proportion than found in sports injuries (27%). In addition, the relative importance of head injuries is considerably higher in swimming pool injuries (35%) than in sports injuries (12%). Swimming pool injuries and sports injuries have equal proportions of patients who are subsequently admitted to hospital (3%). Conclusion: The epidemiology of swimming pool injuries is characterized by a high proportion of 5–14 year-old children and a high share of head injuries. Although the frequency of swimming pool injuries is low, preventive efforts should not be neglected.     

Epidemiology of squash injuries requiring hospital treatment

Abstract

A review of the literature revealed that data on the actual forces that children can exert on products is practically non-existent. For a number of situations, the loads resulting from actions by adults are known. The ratio between body weight and load may be used for estimating the forces that can be exerted by children. The object of the present study was two-fold

to verify the approach of estimating forces by using the body mass of children;

to fill in some of the blanks where no data is available, even for adults

Four different types of peak forces that children can exert on products were selected for the purpose of this study

standing: a push against a horizontal bar

standing: a tug at the bar

sitting: a push with the hands against the bar when sitting with the back against a support

sitting: a push with the feet against the bar when sitting with the back against a support

A total of 203 children participated, ranging from 4 to 12 years of age The methods and equipment used to measure forces are described in the paper. Forces measured and force ratios calculated for different age groups are presented. Some conclusions are:

children can exert higher forces than anticipated, especially when pushing with the feet;

boys are a bit stronger than girls, especially in the higher age groups;

the correlation between weight and forces was high enough in all cases to use body weight as a force indicator;

the ratio between force and body weight is lower in lower age groups.     

Beach safety education for primary school children

Childhood drowning remains a serious public health problem worldwide. The Australian Water Safety Council has set as one of its highest priorities the reduction of drowning deaths in children aged 0–14 years. However, concerns have recently been raised that many students completing primary school still lack the ability to recognize potential aquatic risks, cope with emergencies or assist someone else in danger. In this study, 107 primary school children aged 11–12 completed a one day training programme led by surf lifesaving instructors. Pre, post and eight week follow-up measures showed statistically significant improvements in recognition of the red ‘beach closed’ flag, aquatic safety signs, how to identify a rip current and choosing the safest place to swim at a beach that included a rip current in the picture. Following training students were more willing to provide first aid assistance to family members and friends in an emergency situation. Findings reinforce the value of school-based training that provides a general foundation for aquatic safety, with the caveat that current programmes must be evaluated to ensure their content has a robust prevention focus.     

Determinants of the corporate identity construct: a review of the literature

Corporate identity has received significant attention from both academics and practitioners in the last 25 years. Despite many articles written in this area a definitive construct of corporate identity and its measurements does not yet exist. The objective of this paper is therefore to provide a review of the literature on the corporate identity construct and its components and also to present the academic and managerial implications of this study.     

Segments of sustainable food consumers: a literature review

Sustainable food consumption is an important aspect of sustainable development. When adopting a sustainable food lifestyle, consumers are confronted with complex choices. Today's food consumption is too complex to be explained by socio‐demographic factors exclusively. A broader perspective is needed. In order to explain behaviour across different consumer segments better, relatively homogenous segments of food consumers were identified by segmenting food consumers based on a wide range of variables. The current study aims to provide an overview of published studies that have segmented consumers with regard to sustainable food consumption. The literature review has been conducted by searching SciVerse Scopus for all relevant articles available until November 2010. The main criterion for including a specific study was the inclusion of empirical analyses of primary data, resulting in consumer segments with regard to sustainable food consumption. Sixteen articles were incorporated in the final analysis. First, the variables used for segmentation and profiling in the included articles have been categorized into three levels of abstraction: personality characteristics, food‐related lifestyles and behaviour. The three levels of abstraction proved to be helpful in categorizing the segmentation studies. The findings indicate that variables on all three levels were efficient in differentiating consumer segments regarding sustainability. In addition, the importance of price and health differed across the segments, although these variables are only indirectly related to sustainability. Second, the three most frequently identified consumer segments with regard to sustainable food consumption were: ‘greens’, ‘potential greens’ and ‘non‐greens’. These segments differed from one another on all three levels of abstraction. This implies that future segmentation studies should include variables on all levels of abstraction to get a complete picture of existing sustainable consumer segments. Marketers should be aware that targeting specific segments based on socio‐demographic variables exclusively is not sufficient. Personality characteristics, lifestyle and behaviour are all important to take into consideration. Attempts at stimulating sustainable consumption might be most effective when differences across consumer segments are taken into account. Future research is needed to explore the characteristics of different sustainable food consumer segments with respect to their potential contributions in promoting sustainable development.     

Celebrity endorsements: a literature review and research agenda

This paper presents a narrative review of celebrity endorsement research. The review identifies six areas of research on celebrity endorsements (celebrity prevalence, campaign management, financial effects, celebrity persuasion, non-evaluative meaning transfer, and brand-to-celebrity transfer). A review of the research in each area identifies key findings, conflicting results, and research gaps. In addition, this paper reviews the celebrity endorsement literature with a focus on the psychological processes underlying celebrity endorsement effects that has been put forward in the literature. Based on the review an agenda for future research is offered.

Factors influencing purchase intent in virtual worlds: a review of the literature

Previous empirical studies have identified several factors that seem to play a role in determining purchase intent in virtual worlds; three-dimensional online environments in which users interact while represented by their avatars. So far however, a clear overview of these factors is lacking, and the question that remains is what factors affect purchase intent most. Therefore, this study aims to create an overview of factors that influence users’ purchase intent in virtual worlds, and to subsequently identify the most influential factors. To conduct this review, relevant literature was gathered using a variety of search engines and keywords. An article had to explicitly study factors influencing purchase intent in virtual worlds in order to be included in this review. This search method resulted in a selection of twelve relevant articles that were used for further analysis. Results show that perceived enjoyment, social influence, customization and ease of use are important factors that influence purchase intent in virtual worlds. Enjoyment of the virtual world, beliefs and attitudes of others, avatar customization, and easy-to-use virtual world applications can thus increase users’ willingness to purchase products in the virtual world. Practical implications as well as limitations and suggestions for future research are discussed.     

Relationship marketing in an international context: a literature review

This study identifies and examines the extant literature in international relationship marketing. Twenty-four empirical studies that address various aspects of relationship marketing are identified. However, only eight studies were found to explore marketing relationships across national boundaries. The remainder combine multi-country data or examine relationship marketing in non-US settings. In this review, we report the nature and the findings of these studies and discuss their implications for future research and marketing practice. It is apparent from this review that, despite the increasing importance of international marketing, insufficient attention is being paid to exploring and theorizing relationship marketing in international contexts. Furthermore, limited effort in validating domestic findings in international settings circumscribes the universal applicability and managerial relevance of relationship marketing studies.     

Ethical decision making: A review of the empirical literature

The authors review the empirical literature in order to assess which variables are postulated as influencing ethical beliefs and decision making. The variables are divided into those unique to the individual decision maker and those considered situational in nature. Variables related to an individual decision maker examined in this review are nationality, religion, sex, age, education, employment, and personality. Situation specific variables examined in this review are referent groups, rewards and sanctions, codes of conduct, type of ethical conflict, organization effects, industry, and business competitiveness. The review identifies the variables that have been empirically tested in an effort to uncover what is known and what we need to know about the variables that are hypothesized as determinants of ethical decision behavior.Robert C.

Name-your-own-price as participative pricing strategy: a review of the literature from 2001–2017

ABSTRACT

Name-your-own-price (NYOP), a pricing strategy often referred to as a reverse auction, is a participative pricing mechanism in which consumers have a relatively high control over the price they pay for a product or service. In an NYOP mechanism, buyers generate the final price of a product or service when they bid above an unrevealed threshold price set by the seller. Although NYOP as a pricing strategy was previously investigated, the literature remains scarce and fragmented. This paper attempts to assemble the relevant findings of this pricing strategy, by systematically reviewing all publications from 2001 to 2017. We explored the impacts of this mechanism for companies and consumers, such as increased profit for companies and higher savings for consumers, reduced competition for companies and increased satisfaction for consumers. We also highlighed the best practices of NYOP, such as the bidding practices, threshold price, and willingness to pay.     

Identifying impediments to SRI in Europe: a review of the practitioner and academic literature

For more than 15 years, the investment community and the academic community have written extensively on socially responsible investment (SRI). Despite the abundance of SRI thought, the adoption of SRI practices among institutional investors is a comparative rarity. This paper endeavours to achieve two goals. First, by integrating the practitioner and academic literature on the topic, the paper attempts to identify the many impediments to SRI in Europe from an institutional investor's perspective. Second, the paper proposes a unitary framework to conceptually organize the impediments to SRI by using insights from different relevant research perspectives: behavioural finance, organizational behaviour, institutional theory, economic sociology, management science and finance. The paper concludes by presenting the main shortcomings within both the academic and the practitioner literature on SRI and by providing conceptual and methodological recommendations for further research.     

Business ethics: A literature review with a focus on marketing ethics

In recent years, the business ethics literature has exploded in both volume and importance. Because of the sheer volume and diversity of this literature, a review article was deemed necessary to provide focus and clarity to the area. The present paper reviews the literature on business ethics with a special focus in marketing ethics. The literature is divided into normative and empirical sections, with more emphasis given to the latter. Even though the majority of the articles deal with the American reality, most of the knowledge gained is easily transferable to other nations. John Tsalikis is an Assistant Professor of Marketing at Florida International University. His articles have appeared in the Journal of the Academy of Marketing Science, Journal of Business Ethics, Journal of International Consumer Marketing, and Psychology and Marketing. David J. Fritzsche is a Professor of Business Administration at the University of Portland. His articles have appeared in the Academy of Management Journal, Columbia Journal of World Business, Journal of Macromarketing, Journal of Marketing Research, Marketing Ethics: Guidelines for Managers, and Research in Corporate Social Performance and Policy.     

Product life cycle research: A literature review

The purposes of this paper are threefold: to review the scope of product life cycle (PLC) research; to pinpoint areas requiring further investigation; and to provide guidelines for future researchers. Because of the paucity of empirical evidence, only tentative conclusions are advanced. For example, the most common PLC pattern is the classical, bell-shaped curve, but it is not the sole shape. The application of various forecasting techniques across the PLC have met with merely moderate success. Very little research has been conducted either on how different characteristics of the firm influence the PLC or on the actual use of various PLC-strategy theories by business planners. Finally, investigators have focused almost exclusively on validating the existence of the PLC concept among nondurable consumer goods. Industrial items, as well as major product changes, have been nearly ignored. The main conclusion is that additional research-more diversified and extensive in nature-is needed on many PLC topics.     

Device-mediated customer behaviour on the internet: A systematic literature review

The proliferation of smartphones, tablets and other digital devices in addition to traditional computers has transformed the Internet into a device-mediated environment. While these devices provide immediate access to similar Internet sources, they differ significantly in their characteristics, such as screen size, operation mode and context of use. As a consequence, behaviours on the Internet along the customer journey vary substantially depending on the device used. To summarize the fast-growing body of research on device-mediated customer behaviour, a systematic, framework-based literature review of 59 articles from the last decade was conducted. Through an examination of the antecedents, decisions and outcomes investigated in the publications, the review presents a conceptual framework that highlights the relation between device characteristics, decision processes and behavioural outcomes. The review further summarizes the theories, contexts and methods employed in the studies and sets an extensive future research agenda. We found that the extant literature lacks comprehensive theories and clear definitions of digital devices in the omnichannel environment. Furthermore, existing findings should be generalized for other contexts (e.g. industries and countries) and validated via the introduction of other research designs and methods. The understanding of device-mediated behaviour and the consequently arising marketing measures remains scarce. Thus, this review advances the comprehension of customer behaviour on the Internet and provides researchers and practitioners with information on the implications for customer experience and omnichannel management.     

International human resource management policies and practices of South Korean MNEs: a review of the literature

This paper systematically reviews the literature on international human resource management (IHRM) policies and practices of South Korean multinational enterprises (MNEs). It reveals that South Korean MNEs adopt an ethnocentric staffing approach, but are increasingly using more host-country nationals (HCNs). Korean MNEs pay great attention to language training for expatriates, and there is an emphasis on international experience when selecting expatriates. South Korean MNEs tend to adopt home-oriented selection procedures and criteria, performance appraisal and reward-and-compensation schemes for HCNs. A range of training and development programmes are provided to HCNs in order to develop more local managers. However, studies concerning IHRM of South Korean MNEs are scarce and only a few expatriate-related IHRM issues have been empirically examined. As a result, how South Korean MNEs manage IHRM and what is the rationale of their IHRM policies and practices remain largely unknown. This review paper calls for more empirical research and discusses the implications for future research.
