Timmy and The Magic Box: Practice and Process in Writing for Children
No full textabstract: RIIIIING. The class bells ring to signal the end of the school day for Timmy and his classmates. Mrs. Clark, the boys’ sixth grade teacher, is in the middle of a vocabulary lesson, but as soon as the bell rings everyone rushes out the door. She sets her chalk down on the desk and waves goodbye to everyone as they head home. Timmy and his best friend, Ben, hop on their bikes and start their ride home.
Every day, the boys drive past Merlin’s Magic Shop on the way back from school. Today when Timmy and Ben ride past the store, Timmy sees something new in the window. It appears to be an old box. Wooden, a little worn in, but it still looks like something special.
The boys go inside to ask someone about the box. Towards the back of the store there is an older gentleman stocking the shelves. The gentleman sees the boys looking his way and he begins to head towards Timmy and Ben.
“How do you do?” the man asks. He can tell they are stealing glances at the box, too nervous to ask about it. He points towards the object in the window and says, “You know, that was my old magic box when I was a boy. I thought it looked like it might need a new home.”
Timmy thinks for a moment. The man seems a bit odd—could this really be magic or is he tricking us? By the way he talks, it’s as if he already knows what people are thinking. He knew right away that we wanted that box. He can be standing in the middle of an aisle and in the blink of an eye, he’s gone! Is he magic himself? The store is odd too. You won’t find more than two of an item in there. The store is full of wands and hats and capes, but none of them look the same. Nothing comes in packages or pretty boxes—everything comes as it is, as if it has been used before
Is trust in SEM an intergenerational trait? : A study of sponsored links and generational attitudes towards them
No full textTitle: Is trust in SEM an intergenerational trait? Date: 2018-05-22 Level: Bachelor Thesis in International Marketing Author: Jesper Fredlund 930427 & Timmy Biedron 961128 Supervisor: Henrietta Nilson Problem formulation: How do age correlate with trust and attitude towards SEM on Google in Sweden? Purpose: The purpose of this study is to see if the Swedish Digital Natives are more likely to be trusting search engine marketing, as opposed to the older generations of Digital Immigrants, and by doing this gaining a better understanding of the attitudes towards search engines and search enginemarketing in Sweden. Theoretical framework: The theoretical framework of this paper consists of theories about BannerBlindness, Text Blindness, EHS Theory, Search Engine Marketing, Sponsored Links, Organic Links,Generations. Methodology: This is a quantitative study with 429 respondents in an online survey. It contains Swedish users of search engines divided into groups of those born before 1980 and those born after. Empirical findings: Our study found out that Digital Natives are slightly more likely to favour Search Engine Marketing than Digital Immigrants are. Conclusion: No matter the target of your Search Engine Marketing campaign you should approach itcautiously, since both Digital Natives and Digital Immigrants have been shown to hold a negative bias against these campaigns over organic links.

Travelling microwave reactor design
No full textIn this work, the doctoral thesis of G.S.J. Sturm on microwave reactors was continued. Microwave reactors are developed, because they have potential to increase safety and economically reduce waste. This work focused on microwaves and chemical processes, instead of just heating water, by designing a travelling microwave reactor for non-oxidative methane dehydroaromatization.The travelling microwave reactor was designed using a structured approach. First, the objective was set to an economical conversion to aromatics of otherwise flared methane. Therefore, a successfully designed reactor is able to reduce the CO2 emissions and make many other reactions economical. Secondly, twenty-one challenges for microwave reactors were found using check-lists and a self-developed phenomena exploration method. This method was used to find unknown challenges on the intersection of established engineering fields. Then sub-solutions solving these challenges were extracted from existing reactors and reactor concepts. Finally, a few sub-solutions were selected and forced to work together to obtain the designed reactor.The designed reactor consists of a high performance coated asymmetric annular monolith in an inert container with narrowing conductors in axial direction and an anisotropic porous media. The achieved production volume is three orders of magnitude larger than of a mono-mode microwave reactor at same operation frequency. The designed reactor is capable of obtaining another five orders of magnitude by increasing the temperature up to 1500K, pressure up to 50 atm, catalyst activity with at least two orders of magnitude and lowering the operating frequency. However, only four orders of magnitude were reached, because the designed reactor hit a flow limit.The designed reactor with the three plus four order of magnitude improvement is not yet economical feasible. More advanced designs such as the spiralling narrowing rectangular microwave reactor might be. Furthermore, the designed reactor could become economically feasible in case of a more valuable product. Eventually, this work revealed some unsolved problems and opportunities of microwave reactors as well as information gaps. Moreover, it brought microwave reactors closer to industrial application.<br/

The maritime heritage of Malta : past, present and future
No full textThe concept of this paper materialized from the need to introduce those attending the conference to the host country's history and heritage as seen from the perspective of the sea. This initial introduction was then adapted to act as a platform for a discussion on various aspects of the islands' maritime heritage. Through this paper the author intends to highlight some of these aspects that are either partly overlooked or simply ignored all together. Concrete solutions to the various problems that exist can only be reached through an organised effort conducted by various local bodies. This paper may act as food for thought with regards to the most pressing question, being the identification of what needs to be done. Only once this is established can we truly focus on the how.peer-reviewe
Injury incidence and injury patterns among male elite football players when playing in the national team
No full textBackground: An increased load on the European elite football players is seen; both physically, with more matches with the national teams and the club teams, but also mentally. To play football on the highest level induce a high injury risk with injury incidences very high, both in the national team and in the club teams. Objective: To investigate the injury risk among elite football players in UEFA Champions League when playing in their clubs compared to international matches with their national team respectively. Further the objective also was to study the injury incidence and injury pattern differences between national team players and non national team players. Materials and methods: In this study 3233 player seasons were registered for 6141 injuries from 134 UEFA Champions League team seasons, during the seasons 2001/2002 to 2009/2010. Existing data from UEFA research group consisted of injuries, exposure, anthropometric data etc. The author collected data regarding national team exposure. Definitions of injury severity, injury categorization, injury incidence are standard definitions and the definition of being national team player or not were given by the author. Results: The baseline data showed that the national team players played more matches, had more match injuries, had a higher match exposure and were younger. No large differences are seen in injury incidence in the type of injuries. Some specific injuries as Achilles tendon, low back pain and ACL are more common in matches whit the non national team players, while knee MCL injuries are more common among the national team players. The non national team players had more absence from injuries. When comparing the both groups in injury incidence in total, there were no differences. Discussion: The results of this study can be compared to other similar studies, because of the same procedure regarding injury incidence etc. as consensus. The figures in this study show the same figures as other studies in the same subject. Conclusions: The injury incidence and injury pattern do not diverge from one another or from earlier studies on the same topic. The noteworthy finding is that the players who play for the national team have not a higher injury incidence than the players who do not play for the national team

Issues and directions with educational metadata
No full textThe creation of learning resource metadata by instructors is a time consuming and error prone process. This paper outlines a broad research agenda to mitigate these issues.. The first part of this approach is to collect prescriptive metadata from various actors involved using a light weight collaborative tagging approach. This is then augmented with content analysis done directly on learning objects to create concept and summarization metadata. Finally, interaction metadata observed from the environment in which the learning objects are deployed is interrogate for specific pedagogical purposes, resulting in customized metadata profile for a specific context and goal
Production and maintenance of proper neuron numbers in the developing and aging retina by Nell2
No full textNervous system functionality depends on the generation and maintenance of the proper numbers of neurons. However, the molecular mechanisms that control the number of neurons produced during development and support long term neuronal survival are not fully understood. Nell2 is a multi-modular extracellular glycoprotein predominantly expressed in the nervous system. Nell2 exerts diverse functions in neural development, including regulation of neuronal proliferation and differentiation, and neuronal network formation. Our previous study has shown that Nell2 acts as an inhibitory guidance cue for retinal axons in the eye-specific visual (retinogeniculate) projection. In this study, we investigated the function of Nell2 in neuronal survival by using chick in ovo electroporation and Nell2 knockout mice. Nell2 is strongly expressed in retinal ganglion cells (RGCs) of chick embryos and in mice. Overexpression of Nell2 in the developing chick retina significantly increased RGC numbers, whereas Nell2 knockdown reduced them. Nell2 did not significantly affect neuronal proliferation. However, Nell2 promoted survival of RGCs in the developing retina by preventing apoptosis. In Nell2 knockout mice, the numbers of RGC significantly decreased in the developing retina, due to increased apoptosis. A continuous decrease in RGC numbers and increase in apoptotic RGCs were found in the aging Nell2 knockout mice. Furthermore, we detected Ros1 expression, a receptor tyrosine kinase that binds to Nell2, in RGCs by immunohistochemistry. These results suggest that Nell2 acts as a survival promoting factor essential for production and maintenance of proper numbers of RGCs, and that Ros-1 may be a receptor for Nell2 in RGCs
