Mediating Variables in a Parent Based Intervention to Reduce Skin Cancer Risk in ChildrenTurrisi, Rob, Hillhouse, Joel, Robinson, June K., Stapleton, Jerod 01 October 2007 (has links)
The present study examined theoretical mediators of a parent-based intervention on sunbathing tendencies and sunburn frequencies based on the work of Turrisi et al. [Turrisi, R., Hillhouse, J., Heavin, S., Robinson, J., Adams, M., & Berry, J. (2004). Journal of Behavioral Medicine, 27, 393-412.]. Three hundred and forty parents in two regions of the United States were educated about the dangers of risky sun behavior and how to convey information about skin cancer prevention to their children. Attitudes toward sunbathing, health beliefs, appearance beliefs, and social normative beliefs were examined and found to be significant mediators of program effects on sunbathing tendencies and sunburn frequencies. The findings are discussed with respect to maximizing the effectiveness of future skin cancer interventions with children.

Determining the alignment of Solar Orbiter instruments STIX and EUI during solar flaresTynelius, Sofia January 2022 (has links)
Solar Orbiter is a mission launched in 2020 that will take images closer than ever of the Sun. It has ten instruments on board, including The Spectrometer/Telescope for Imaging X-rays (STIX) and The Extreme Ultraviolet Imager (EUI). STIX is a hard X-ray imaging spectrometer which observes bremsstrahlung from the non-thermal accelerated electrons in the footpoints of solar flares and from thermal hot plasma in flare loops. EUI consists of three telescopes, including a Full Sun Imager which is a one-mirror telescope that observes the solar corona and chromosphere in extreme ultraviolet (EUV) wavelengths 174Å and 304Å, respectively. The purpose of the project was to determine the alignment between STIX and EUI to better understand and improve the pointing of STIX. It is important to know the accuracy of the pointing before using the instruments for science. The alignment was studied by looking at the flare location of the two instruments for about 30 flares. The flare location was approximated to be the brightest pixel in the image. The aspect solution of STIX was applied and this was also compared to the flare seen by EUI. For some of the flares, also imaging data from the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory (SDO) was used to get a more detailed comparison. One flare was studied in more detail, using thermal and non-thermal emission seen by STIX, EUV emission seen by EUI 174Å and AIA 171Å as well as UV emission seen by AIA 1600Å. For four flares, the flare location was determined from the visible ribbons and loops instead of the brightest pixel. The methods of finding the flare location by brightest pixel and by looking at flare features were compared. The average difference between the EUI and STIX flare location was within 12 arcseconds with a standard deviation between 18 and 42 arcseconds for the brightest pixel method. This difference has two main contributions: the accuracy of the STIX aspect solutions and the accuracy of identifying the common source features in EUV and X-rays. To increase the accuracy of finding common sources, four flares with well defined ribbons and loops were analyzed in detail. For these events, the accuracy of the STIX aspect system was determined to be better than 10.5 arcseconds. This is still significantly higher than the design requirements of being better than 4 arcsecs. Detailed analysis clearly showed that the method of determining the flare location by brightest pixel was not accurate enough to evaluate the STIX pointing. Further studies need to be done to improve the aspect solution.

The perspectives of stakeholders about the impact of incorporating chess into the curriculum practice in King Cetshwayo District Primary SchoolsDlamini, NtandokaMenzi Penelope, Maphalala, M.C 12 1900 (has links)
A thesis submitted in fulfilment of the requirements for the Degree Doctor of Philosophy for the Department of Curriculum and Instructional Studies, Faculty of Education at the University of Zululand, 2018. / The continuous protest from various quarters of society about the weakening education standard are a concern. Chess has been found to be a solution to remedy this problem in many countries through studies testing its effectiveness on the learners. However, very little is said about the teachers who are key in the success of this integration. This study aimed at getting the perspectives of the stakeholders regarding the incorporation of chess into the curriculum in the four subjects in the Foundation Phase, namely, isiZulu, English, Mathematics and Life skills.
This qualitative design research looks at the perspectives of the stakeholders about the impact of incorporating chess into the curriculum practice through the Tsogo Sun Moves for Life programme piloted in the King Cetshwayo district. Through interviews, observations and document analysis, this study acquired the insights of 14 teachers who work as Tsogo Sun Moves for Life facilitators in schools under the programme, the district official who is tasked with ensuring that the curriculum is well delivered in schools, and the Tsogo Sun Moves for Life co-ordinator who assist the facilitators in incorporating chess into the curriculum.
The study reveals that teachers find chess to be helpful as it helps the learners learn better while having fun, their attention span is increased, and they tend to concentrate better when chess is integrated. However, the teachers face many challenges as they struggle to merge chess into the curriculum, from those who view it as an add- on detached from the curriculum, and therefore see it as additional workload for them. The language used in the chess instruction appeared to be a challenge as the chess resources are not written in the learners’ home language.

Investigation of the magnetic fields of a young Sun-like star ∏1 UMaAhmedi, Lawen January 2020 (has links)
In astronomy, the Sun has an important role. It keeps the solar-system together and is thesource for life, heat, light and energy to Earth. As any other star or planet, the Sun has amagnetic field. The magnetic field of the Sun has a great impact on the Sun itself as well asits surrounding. The magnetic field shapes solar wind, causes flares and drives coronal massejections radiating towards the Earth (and other planets). The Sun's magnetic field is still notfully understood, and therefore it is useful to study other stars with properties similar to theSun. So by studying young solar-type stars, the evolution of the Sun can be more easilyunderstood. The aim of this project is to study the surface magnetic field in a youngsolar-type star, π1 UMa to see how the magnetic field is distributed and if there are anypatterns like polarity reversals. Magnetic field generates polarisation and with Stokes vector Iand V, polarisation can be described. Earlier measurements from two time-epochs (2014 and2015) of Stokes I and V have been obtained from the spectropolarimeter NARVAL. To getthe desired mean polarisation profiles of the star, a technique called least squaredeconvolution was applied which increases the signal-to-noise level. To reconstruct themagnetic topology the Zeeman-Doppler imaging technique was used. Then we obtained thesurface magnetic field maps of both measurements. No change of the polarity of magneticfield at the visible stellar pole was found. Most of the magnetic field energy was contained inthe spherical harmonic modes with angular degrees l=1-3. The star shows dominance in thetoroidal component so the study seem to agree with the previously established trend thatyounger and faster rotating stars have predominantly toroidal magnetic fields and older starswith slower rotation rate, like the Sun, have predominantly poloidal field. Looking at themagnetic field plots, the star show dominance in the azimuthal field component, and themean magnetic field strength is similar to one found in the previous study. The results of thesurface magnetic field in our study thus agrees with previous study of the same star. With thiswe can conclude that the Sun's magnetic field probably been different when it was younger, and possibly similar to the star analyzed in this study.

Insecticide Treated Nets as an Effective Malaria Control Strategy in LiberiaQuenneh, Taiyee Nelson 01 January 2016 (has links)
Malaria is a vector-borne disease that presents the most persistent and serious public health burden in Liberia. Numerous studies have examined the relationship between ITN use and malaria prevalence. However, little research has explored the effectiveness of ITNs in controlling malaria among children in postwar Liberia. The aim of this study was to examine the association between ITN ownership, parental economic status, ITN installation support, and malaria prevalence among children. This was a quantitative cross-sectional study guided by the health belief model. The study used secondary data from the 2011 Liberia Malaria Indicator Survey. Chi-square for association and Logistic regression were used to analyze the data. The results revealed a significant association between parental education and malaria prevalence. There was also a significant association between parental economic status and malaria prevalence. However, there was no significant association between ITN ownership and malaria prevalence after controlling for parental education and ownership of structure. These findings may foster social change by helping public health authorities in Liberia integrate ITN use with other strategies like mosquito larvae elimination and indoor/outdoor insecticide spraying as part of a comprehensive approach to malaria control. Additionally, massive awareness and economic capacity building should be undertaken to empower malaria endemic communities with the understanding that malaria can be rapidly reduced with other robust strategies in combination with ITN use. These strategies, if implemented, may effectively control malaria prevalence among children and the emotional and financial burdens endure by their families.

Cooling OasisRizvani, Lejla January 2021 (has links)
The urban heat island, UHI, is a phenomenon that occurs in all cities. This phenomenon is an effect of us humans and the environments we have built. What happens in cities are that they re-emit the suns heat and other energies trapping them in this heat island. The re-emitting happens through the pavement of the city, lack of greenery, roads and how the city is built and its geometry. Cities with skycrapers and of high density see a greater impact of the urban heat island where the wind flow is reduced and more heat is trapped and stored. The UHI is worst experienced in places with a very hot climate, such as the arid desert climate with extreme temperatures year round, like in the UAE and Dubai. It is vital to tackle the UHI effect problem, because it puts people at danger. Many lives are shed each year due to heat strokes, that can be reduced if we take this problem into consideration when we design our cities. The UHI effect can be reduced by simple yet effective steps.

Sun Tunnel / Sol tunnelMattsson, Nicodemus January 2018 (has links)
This thesis project aims to repurpose an abandoned railway tunnel in Eriksdalslunden, Stockholm into an experimental activity/farming center for the purpose of teaching people of all ages different farming methods. The learning center implements exciting farming techniques such as aquaponics, where plants get their nutrients from live fish. This center also teaches about the new technologies that make it possible to grow plants beneath the earth´s surface. These technologies harness the benefits of the sun into a concentrated form and then leads it deep underground. Repurposing unused underground spaces such as this can help develop our cities in a more efficient way. / Detta avhandlingsprojekt syftar till att omarbeta enövergiven järnvägstunnel i Eriksdalslunden,Stockholm till en experimentell verksamhet / jordbrukscentrum för att undervisa människor i alla åldrar olika odlingsmetoder. Inlärningscentralen implementerar spännande odlingstekniker som aquaponics, där växter får sinanäringsämnen från levande fisk.Detta centrum lär också om den nya tekniken som gör det möjligt att växa växter under jordens yta. Dessa tekniker utnyttjar solens fördelar i en koncentrerad form och leder sedan den djupt under jorden. Repurposing oanvända underjordiska utrymmen som detta kan hjälpa till att utveckla våra städer på ett mer effektivt sätt.

Homicide In The Headlines An Analysis Of The Newspaper Reporting Of Baltimore Homicides Of 2010Schildkraut, Jaclyn V 01 January 2011 (has links)
Baltimore is notorious for its recent and storied history of crime. The current study examines the treatment of homicide victims in Baltimore newspapers. In 2010, 222 homicides occurred in Baltimore, according to the city‟s homicide map. One hundred and sixty-five were discussed in The Baltimore Sun, the city‟s most-circulated paper. Based on the inclusion or exclusion of particular cases and the manner in which cases were discussed, conclusions can be drawn about the media‟s perception of a case‟s newsworthiness. Specifically, cases with particular details that varied significantly from a “normal” homicide were found to be most newsworthy, determined in part by analyzing the frequency of reporting, placement of coverage within the newspaper, and word count allocated to the discussion of crime.
