This paper aims to examine the perceptions of the visual packaging of snacks and nutrition knowledge among preschool children. Packages serve as persuasive media at the point of purchase.

In this paper 13 interviews with four-year-olds were conducted. Children sorted seven snacks that implied fruit into categories based on perceptions of fun, taste, parent’s choice and “nutrition”. Children also drew trees with food that would make them healthy or not healthy.

Children attended to the package elements more than the product. All children selected the character fruit snack as their preferred choice; however, perceptions for fun and taste varied among snacks. Perceptions of healthiness showed evidence of heuristics (e.g. sugar = bad; fruit = good). Some children were able to understand that their parents’ choices may be different from their own.

Because of the small sample size, it is not possible to generalize results to all children. Children seemed to understand that the character may not convey “healthy” or “taste”, but they still chose the snack with a character.

Children as young as four can understand nutrition heuristics and may/may not use those heuristics in product preferences.

Children may be able to reason about their own preferences and others’ preferences at a preoperational stage of development.

Previous research indicates that older children are attracted by characters. The findings show that younger children also prefer characters but may be capable of disentangling the various associations of “characters”.

The purpose of this paper is to examine the behaviors and social interactions among preschool children and their teachers during food consumption at a daycare facility. Using social cognitive theory, the goal is to identify how role modeling, rules, behaviors and communication shape these young consumers’ health-related food consumption and habits.

This study was conducted in a US daycare facility among preschool children (aged four years) over a three-month period. Qualitative ethnographic methods included participant and non-participant observation of meals and snack-time.

Findings from the observations revealed that teachers’ food socialization styles and social interactions with peers cultivate children’s food consumption. In addition, commensality rules set by the childcare institution also help children learn other valuable behaviors (e.g. table manners and cleaning up).

The study was conducted in one location with one age group so the results may not be generalized to all children. As more young children spend time in preschools and daycare centers, the understanding of how these settings and the caregivers and peers influence them becomes more important. Preschool teachers can influence their young students’ food consumption through their actions and words. Training teachers and cultivating educational programs about ways to encourage healthy eating habits could be implemented.

The paper offers observations of actual behaviors among young children in a naturalistic setting.

This study highlights the demand for low-cost and high accuracy products through the design and development of new 3D printing technologies. Besides, significant progress has been made in this field. A comparative study helps to understand the latest development in materials and future prospect of this technology.

Nevertheless, a large amount of progress still remains to be made. While some of the works have focused on the performances of the materials, the rest have focused on the development of new methods and techniques in additive manufacturing.

This paper critically evaluates the current 3D printing technologies, including the development and optimizations made to the printing methods, as well as the printed objects. Meanwhile, previous developments in this area and contributions to the modern trend in manufacturing technology are summarized briefly.

The paper can be summarized in three sections. Firstly, the existing printing methods along with the frequently used printing materials, as well as the processing parameters, and the factors which influence the quality and mechanical performances of the printed objects are discussed. Secondly, the optimization techniques, such as topology, shape, structure and mechanical property, are described. Thirdly, the latest development and applications of additive manufacturing are depicted, and the scope of future research in the relevant area is put forward.

The purpose of this paper is to explore the influence that adopting open innovation (OI) has on the innovativeness and performance of specialized small and medium-sized enterprises (SMEs). This paper also examines the adoption of OI within a firm’s practices and models, and within the three dimensions of firm sustainability.

Survey data from 48 specialized SMEs manufacturing supercars were analyzed using partial least squares structural equation modeling. SmartPLS software was used to conduct a path analysis and test the proposed framework.

The findings suggest that high adoption of OI models tends to increase firm innovativeness. Similarly, the adoption of OI practices has a positive effect on innovativeness but to a lesser extent than OI models. The moderation results of innovativeness further show that OI models and practices can benefit the performance of SMEs. Specifically, two dimensions of performance – environmental and social performance – were found to be greatly influenced by OI.

Due to parsimony in the investigated model, this study only focuses on OI adoption as practices and models without considering its drivers or other contingency factors.

This paper could help practitioners in SMEs better understand the benefits of adopting OI to be more innovative but also more sustainable.

This study contributes to the literature on the role of OI practices and models regarding the dimensions of firm sustainability performance by being the first paper to investigate this relationship in the context of small and medium manufacturers of supercars.

This paper aims to evaluate the sulfide stress cracking (SSC) resistance of L80 casing steels with different alloying chemistries (e.g. Ti-B and Mn-Cr-Mo) by correlating the reduction in area ratio with the mechanical property, inclusion and carbide.

SSC tests were conducted in 5.0 Wt.% sodium chloride and 0.5 Wt.% acetic acid solution saturated with H₂S using constant load tensile method. The microstructure and fracture morphology of the steel were observed using scanning electron microscope. The inclusion and carbide were identified by energy dispersive spectroscopy and auger electron microscope.

Among all the testing steels, electric resistance welding (ERW) L80-0.5Mo steel demonstrates the highest SSC resistance because of its appropriate mechanical properties, uniform microstructure and low inclusion content. The SSC resistance of L80 steels generally decreases with the rising yield strength. The fracture mode of steel with low SSC resistance is jointly dominated by transgranular and intergranular cracking, whereas that with high SSC resistance is mainly transgranular cracking. SSC is more sensitive to inclusions than carbides because the cracks are easier to be initiated from the elongated inclusions and oversized oxide inclusions, especially the inclusion clusters. Unlike the elongated carbide, globular carbide in the steel can reduce the negative effect on the SSC resistance. Especially, a uniform microstructure with fine globular carbides favors a significant improvement in SSC resistance through precluding the cracking propagation.

The paper provides the new insights into the improvement in SSC resistance of L80 casing steel for its application in H₂S environment through optimizing its alloying compositions and microstructure.

Despite growing attention to physician engagement there is a lack of literature to guide the development of physician-led interventions. A scoping review was conducted to describe physician-led strategies that have been implemented to promote increased physician engagement in acute care settings. Strategies are viewed through the theoretical lens of institutional work to advance the understanding about how the theory can be applied. The paper aims to discuss this issue.

Searches were conducted in English-language publications (2012–2017). Of 35 retained articles, 15 were from the gray literature; and 20 were peer reviewed. The review was guided by Arskey and O’Malley’s (2005) five-stage process.

Five themes reflecting different foci of physician-led activity were examined from the perspective of institutional work: systematically analyze context using participatory methods; work collaboratively toward locally defined, shared targets and build in processes to monitor progress; expand physicians’ role and capacity to include leadership toward shared organizational goals; promote appropriate rewards and incentives for work that builds engagement; and invest in opportunities for formal and informal communication and interaction.

Physicians considering action to increase their engagement in system improvement may benefit from analysis of local opportunities and barriers in selecting context-relevant activities that will motivate participation and build engagement through a balance of institutional work.

The paper considers the potential for physicians to initiate and support activity that will increase their engagement. It provides pragmatic strategies for designing intervention and research using the theoretical lens of institutional work.
