Car transportable personal shopping cart
No full textThe average shopper in the US goes to the shopping mall more than two times a week for groceries and other items. During the shopping consumers often use shopping carts to move larger quantities of items than they can carry. But the shopping cart that is currently used to increase the carrying convenience of moving groceries stops at the car. From that point on there is still quite a lot of transporting to do to get the bought items to the place where they need to be. This step to step moving of the items results in inconvenience for the consumer. And there are currently no real solutions to make this easier accept bundling items in bags at the cashier, this only takes partial care of the problem. The overall process is a discontinues sequence of steps, and the develop product should help to unify and streamline this process. The project aims to create a product that makes the transportation of groceries from the aisle to the kitchen a more continues process. And doing this by using a product that is prepared for the future of shopping by considering trends and upcoming changes of the (groceries) market. In the end the goal was to create a product that increases the convenience of transporting of bought items. But that also gives the consumer the feeling that they are dealing with an evolution of the shopping cart. And in general streamlines the overall experience of transporting bought items from the shelve to the consumer’s house. The result of the project is the personal shopping cart concept. The cart consists of a shopping basket with a foldable set of wheeled legs mounted to the side of the cart. These wheels enable the cart to slide into the opened trunk of a larger size car (SUV). This is made possible by sliding tracks at the front and bottom of the cart that allow the basket to ‘ride’ in and out of the trunk. The handle pushes the legs together creating a lifting motion to get the cart to trunk height. After that, the user can keep pushing and move the legs upwards, and push them inwards into the car. Additional functionality for the cart is a higher, smaller version. The two halves of the basket slide inward to form a basket that is significantly decreased in size. Then the wheeled legs can be moved towards each other, lifting and decreasing the footprint of the cart. This transforms the cart from a large groceries shopping cart into a smaller more agile retail cart. For this graduation project four stakeholders were involved (University of technology Delft, Graduate student, Design firm and the Client) with all a different goal for the project. So the project was also a balancing act to fulfill all the goals of the involved parties. With the ultimate goal to at the end have one graduated student and one product concept. So next to the development of the concept for graduation, the client was also to be taken along in the process that is required to create a product concept. The project was executed in collaboration with the Dutch/German design firm Design2Gather based in Shanghai, China. The majority of the time spend on this project was conducted from the office in Shanghai. And the project was finished in Delft, The Netherlands.Industrial Design EngineeringDesign Engineerin
La mobilité professionnelle des apprentis et ses effets salariaux. Les enseignements de l’enquête Génération 2004
No full textNous analysons la mobilité des apprentis à la fin de leur contrat de formation. Le contrat d’apprentissage est en effet un contrat à durée déterminée particulier, à l’issue duquel l’apprenti peut être embauché ou non par l’entreprise où il a été formé. Le premier objectif est d’identifier les formes et les déterminants de la mobilité des apprentis. Celle-ci résulte à la fois des mécanismes de sélection à l’oeuvre sur le marché du travail et de comportements plus actifs de la part des apprentis en matière de recherche d’emploi dans le but de réaliser des appariements de meilleure qualité avec les entreprises. Le deuxième objectif est d’estimer les effets de cette mobilité sur le salaire des apprentis. Sur le court terme, les estimations que nous avons menées montrent que les niveaux de salaire à l’embauche des apprentis mobiles ne sont pas significativement différents de ceux des immobiles. Les déterminants du salaire ne sont toutefois pas identiques pour les deux populations. Sur le moyen terme, les écarts de salaire se creusent à l’avantage des apprentis qui ont été embauchés dans l’entreprise où ils ont été formés. Si l’on affine l’analyse, ce sont les cas de mobilité différée, c’est-à-dire les apprentis embauchés à la fin de la période de formation mais changeant d’entreprise après quelques mois, qui connaissent les évolutions de salaire les plus importantes. La mobilité profite donc surtout aux apprentis qui avaient d’abord été recrutés par leur maître d’apprentissage.Cart Benoit, Léné Alexandre.

Greentom Go: Designing a circular and sustainable hand cart
No full textThe main objective of this graduation was to design a sustainable hand cart product concept for young families in the Netherlands, which is simple in its design, easy to use, and affordably priced. The hand cart should furthermore be suitable for up to three children to sit in and suitable to transport goods. Research was done on current hand carts on the market, on users' experiences with them, and on the current sustainability and circularity of Greentom's currently produced product. This research resulted in a list of users' needs and wishes in a hand cart, including the ideal dimensions, needed safety norms, needed requirements for it to be easy to use, and the selling price preferred to be under €250. Furthermore, the research concluded that rPP and rPET are the most suitable and sustainable materials to be used in the hand cart chassis and textile respectively, and that an end-of-life scenario where new Greentom products are sent back and refurbished into 2nd-life products would result in hand carts with 62% lower eco-costs and 71%€ value capture compared to the product with a linear incineration end-of-life. By using these concluded required elements of a hand cart, and by defining the Greentom form family and future hand cart style, several ideas were developed after which five product ideas were proposed. The five ideas showed promising iterations on the basic frame structure, folding principle, push/pull bar design, and bottom design. By detailing their ergonomic and constructional aspects, which concluded the exact dimensions, necessary wheel types, push/pull bar positioning, weight-support beam construction, and necessary folding structure iterations, the ideas were concretized into three concepts: 'Horizontals', 'Twofold', and 'Diagonal'. The concepts were evaluated based on three main criteria from the list of requirements, after which the 'Diagonal' was concluded to be the most promising concept to be further developed into detail. Detailing the concept was done by defining the to-be-improved points with a structural mock-up model, and by defining and further developing satisfier and exciter attributes to ensure a high degree of customer satisfaction using the KANO model. Lastly, after building a 1:1 functional prototype of the improved final concept, the prototype was evaluated by means of a user test, and showed to successfully satisfy all users' needs and wishes with positive reactions on all attributes. The final design, the 'Greentom Go' concludes to be 1) simple in its design since it complies with Greentom's form family style while also expressing its own Hand Cart style, 2) easy to use as it is easily (un)foldable, enables children to independently step in and out of the hand cart, allows attachment of Greentom accessories and a baby car seat, and is well manoeuvrable by having large wheels, a pushable handlebar, and by being lightweight (7.57kg), and 3) affordable since the reuse of existing and future moulds as well as the refurbishment end-of-life scenario allows for lower total costs enabling a selling price of €220. Therefore, the stated design goal is concluded to be successfully achieved by the Greentom Go.Integrated Product Desig
Apprenticeships, mobility and wages an investigation on French data
No full text
Purpose
The purpose of this paper is to estimate the effect of mobility on the apprentices’ wages.
Design/methodology/approach
Using a French longitudinal survey concerned with young people’s entry into the labor market and their subsequent employment trajectories, this paper estimates the impact of mobility on post-apprenticeship wages correcting for different selection bias.
Findings
Mobility is both voluntary and enforced. It combines imposed selection mechanisms and more active match searching behaviors on the part of apprentices. Apprentices who change employer do not have significant lower starting wages than those who remain in their training firms. Nevertheless, in the medium term, those who defer their moves tend to benefit more from their mobility. Those who move immediately see their wage rising less sharply.
Practical implications
The findings indicate that policy makers should be concerned with job mobility at the end of the apprenticeship contract. Manpower policies should focus on measures that enhance the transferability of accumulated skills and the acquisition of new skills by apprentices.
Originality/value
To the author’ best knowledge, this is the first paper studying the effect of mobility on apprentices’ wages in a dynamic perspective and correcting for the selection of different categories of mobility (immediate vs deferred mobility).

An application of CART algorithm in genetics: IGFs and cGH polymorphisms in Japanese quail
No full text2nd International Conference on Advances in Natural and Applied Sciences (ICANAS) -- APR 18-21, 2017 -- Antalya, TURKEYThe avian insulin-like growth factor-1 (IGFs) and avian growth hormone (cGH) genes are the most important genes that can affect bird performance traits because of its important function in growth and metabolism. Understanding the molecular genetic basis of variation in growth-related traits is of importance for continued improvement and increased rates of genetic gain. The objective of the present study was to identify polymorphisms of cGH and IGFs genes in Japanese quail using conventional least square method (LSM) and CART algorithm. Therefore, this study was aimed to demonstrate at determining the polymorphisms of two genes related growth characteristics via CART algorithm. A simulated data set was generated to analyze by adhering the results of some poultry genetic studies which it includes live weights at 5 weeks of age, 3 alleles and 6 genotypes of cGH and 2 alleles and 3 genotypes of IGFs. As a result, it has been determined that the CART algorithm has some advantages as for that LSM.Agri Ibrahim Cecen Univ, IC Fd
Copyright and Creativity: Authors and Photographers
Get PDFThe history of the occupations “author” and “photographer” provides an insightful perspective on copyright and creativity. The concept of the romantic author, associated with personal creative genius, gained prominence in the eighteenth century. However, in the U.S. in 1900 only about three thousand persons professed their occupation to be “author.” Self-professed “photographers” were then about ten times as numerous as authors. Being a photographer was associated with manufacturing and depended only on mastering technical skills and making a living. Being an author, in contrast, was an elite status associated with science and literature. Across the twentieth century, the number of writers and authors grew much more rapidly than the number of photographers. The relative success of writers and authors in creating jobs seems to have depended not on differences in copyright or possibilities for self- production, but on greater occupational innovation. Creativity in organizing daily work is an important form of creativity.occupations, authors, photographers, copyright law, economic history
Establishing Solidarity in Beverage Cart Service Encounters
No full textIn this study positive politeness and the creation of solidarity were examined. In the article Friendly but Strangers: Self Disclosure and the Creation of Solidarity at Service Encounters in America author Risako Ide (1997) described the discursive methods that she observed to create solidarity between servers and customers in service encounters. The discourse of beer cart service encounters was studied to determine if solidarity was created through similar methods.
The study was ethnographic as subjects were observed in their own environment. The data was collected at a golf course where golfers were served beverages from a cart. Service encounters between the server and the customers were tape recorded by the server, Meghan Koch. An hour of service on the beer cart was recorded and 6 encounters were transcribed for a total time of 7 .6 minutes. Service encounters were selected because of their length and clarity.
It was found that the methods observed to create solidarity in beer cart service encounters were similar to the methods Ide observed in her study. Additional examples of positive politeness were observed in beverage cart service encounters. Furthermore, the studies differed when it came to the actions of the server and the customer.
In conclusion, the practice of creating solidarity through various methods is common in service encounters. Service encounters on the beer cart appear to be similar to more common types of service encounters in America. However, they present a unique customer/server interaction that is worth examining further

A lightweight cart frame design that makes use of topology optimization
No full textTopology optimization is a bio-inspired optimization method based on the growth of bones. With this method, the optimal material distribution with the minimal amount of material for a product can be defined. This could help engineers to create innovative lightweight designs and get rid of benchmark and pervious design on which current designs are commonly based. The goal of this graduation project is to show that topology optimization is useful as a source of inspiration for commercial companies to create innovative lightweight designs. Therefore, a design assignment is performed for a baggage cart frame design. The new cart frame design is based on the topology optimization in 3D. In the end, the new design is compared with four concepts designed by the company to show that the use of topology optimization resulted in a lighter and more innovative design.Mechanical, Maritime and Materials EngineeringMechanical EngineeringBiomechanica
