1	COMPARATIVE ANALYSIS OF RURAL AND URBAN START-UP ENTREPRENEURS Joo, Hyunjeong 01 January 2011 (has links) This study investigates the reasons for apparent differences in entrepreneurship rates in rural and urban areas using a Survey of Rural Kentucky Residents (SRKR) and the Panel Study of Entrepreneurial Dynamics (PSED) data. We estimate the determinants of dissimilar characteristics for rural and urban areas in two aspects: one is individual and contextual resources; the other is cultural tendencies of resources. The results of the analysis suggest that the difference in available individual, economic, and social support resources does not explain the observed difference in entrepreneurship rate. The results also indicate that gender, ethnicity, income, and number of children in the family have different effects on entrepreneurial intentions in rural and urban settings. The results suggest that policy makers need to account for cultural or geographical differences when designing entrepreneurial educational and support programs in order to enhance the establishment of new business between rural and urban areas.

2	The Impact Of Using A Computer Algebra System In High School Calculus On High Performing Students' Conceptual And Procedural Understanding Bawatneh, Zyad 01 January 2012 (has links) Recently, there has been an increasing interest in high school mathematics education, especially in the teaching and learning of calculus. For example, studies conducted by Bressoud (2010); Judson and Nishimori (2005); Koh and Divaharan (2011); and St. Jarre (2008) all looked at how to improve the understanding of calculus students and what roles the educator must take to ensure that their students are successful. The purpose of this study was to determine if there was a significant difference between instruction using computer algebra system (CAS) compared to instruction using the graphing calculator in high school calculus on students’ conceptual and procedural understanding. This study explored and compared two different types of instruction based on the use of two different types of technology, CAS and graphing calculator. The total population for this study consisted of 333 students. There were 187 students classified as using the graphing calculator and 146 students classified as using CAS. The data for this study were collected from four Advanced Placement (AP) calculus AB courses from high schools in Florida. The study used observations and two sets of calculus tasks in order to gather data. The research questions for this study looked at comparing the grades of students categorized based on the type of instruction received during the learning of calculus. The statistical procedure that was used was a simple oneway analysis of variance (ANOVA). The results indicated that there was no significant difference between the two types of instruction on the students’ procedural knowledge, iii however, there was statistical significance on the students’ conceptual understanding in favor of the CAS students. The study introduces a framework on how to obtain information about the effects of different types of instruction on students’ understanding of calculus. The results of this study contribute in assisting teachers and future researchers on how to analyze student work in order to obtain information about the students’ conceptual and procedural understanding of first semester calculus.

3	土地徵收補償之地價分析 / An Analysis on Land Value of Land Expropriation Compensation 劉庭如, Liu, Ting Ju Unknown Date (has links) 2013年9月1日起，土地徵收將改採「市價」作為地價補償之基準，期以實現土地之「公平正義」。在文獻回顧中，本文歸納合理的徵收補償為在符合現行法令下，交易市場中最可能的價格。即不論由時間軸，亦或地區範圍軸作觀察，都應為合理之價格，不存在非正常上漲之情形。本文蒐集2011年至2013年桃園航空城範圍內外之成交案例，運用獨立樣本t檢定，分析範圍內之成交價格是否會受到其開發計畫之影響。研究結果顯示，無論是區分範圍內外，抑或從土地使用分區或分季觀察，範圍內之平均成交價格皆受到航空城計畫之影響，與範圍外相同用地之成交價格，呈現非常顯著之差異。若依據現行的土地徵收補償市價查估辦法，在限制案例蒐集時間下，估算補償價格時無法避免參考非正常上漲之成交價格；此外，將收益法視為配角，亦會導致當比較法之估算價格有所偏頗時，無法由收益法作為權衡，合理的估算補償價格。 / From September 1st on , the government changed to adopt market value as expropriation compensation, in order to practice justice of land. In Literature Reviews, this paper generalize the definition of reasonable expropriation compensation is the most probable price in the market according to current law. In other words , this reasonable price can not rise sharply through the aspect of time and region. This paper collected the transaction price of Taoyuan Air City from 2011 to 2013, then using independent t-test to analyze that will Taoyuan Air City have impact on the transaction price. The empirical results showed that whether from the inside or outside of Taoyuan Air City or zoning or observation from different period, the transaction price must be influenced by Taoyuan Air City, resulting in manifest difference between the inside transaction price and the outside transaction price. Under the limited time of collecting market cases, the government can not avoid estimating unreasonable expropriation compensation according to the current law; Besides, the Income Capitalization Approach is treated as a supporting role which would lead to unreasonable expropriation compensation because of unbalanced prices. 土地徵收補償市價查估辦法桃園航空城徵收補償獨立樣本t檢定 Taoyuan Air City expropriation compensation independent t-test
4	GRAVIDA KVINNORS INTAG AV KOSTTILLSKOTT : En kvantitativ studie med fokus på järn och probiotika / PREGNANT WOMEN´S INTAKE OF DIETARY SUPPLEMENT : A quantitative study focusing on iron and probiotics Lange Bålman, Miriam January 2019 (has links) Sammanfattning Bakgrund Vitamin- och mineralbrister hos gravida kvinnor kan leda till missfall och allvarliga störningar i barnets utveckling. Moderns tarmflora överförs med stor sannolikhet till barnet under förlossningen och kan därför innebära ett viktigt steg i utvecklingen av barnets tarmflora. En tänkbar lösning för att säkra ett adekvat intag kan vara konsumtion av kosttillskott och probiotika. I dagsläget finns osäkra uppgifter om hur många gravida kvinnor som intar tillskott. Syfte Att undersöka hur många gravida kvinnor i Västerbottens län som valde att inta kosttillskott, främst järn och probiotika, samt om det fanns en skillnad mellan olika faktorer och intag. Metod En kvantitativ tvärsnittsstudie där gravida kvinnor (n=1473) från Northpop-studien i Västerbottens län svarade på ett frågeformulär gällande intag av kosttillskott och faktorer som ålder, utbildning, kostregim etc. De statistiska tester som användes var Chi-2-test, oberoende t-test och Mann Whitney U-test. Materialet analyserades i SPSS. Signifikansnivån sattes till p<0,05. Resultat Majoriteten av deltagarna svarade att de intog kosttillskott. Faktorer som ökade intaget av kosttillskott hos gravida kvinnor var högre ålder (p=0,030) jämfört med lägre ålder, högre utbildningsnivå (p=0,006) jämfört med lägre utbildningsnivå och vegetarisk/vegansk kost (p=0,021) jämfört med blandkost. Femtiofem procent uppgav att de intog järntillskott. De faktorer som ökade intaget av järntillskott hos gravida kvinnor var vegetarisk/vegansk kost (p=0,001) jämfört med blandkost. Probiotika intogs av 2 procent. Ett högre intag av probiotika sågs hos personer boende i stadsområde (p=0,024) jämfört med övriga boenderegioner samt de som åt vegetarisk/vegansk kost (p=0,001) jämfört med blandkost. Slutsats Majoriteten av deltagarna intog någon typ av kosttillskott, hälften intog järntillskott och en liten andel intog probiotika. Lågutbildade, yngre, de som äter blandkost och bor utanför stadsområde verkar vara i riskgruppen för att inte inta kosttillskott. / Abstract Background Vitamin and mineral deficiencies in pregnant women can lead to miscarriage and serious disturbances in children’s development. The intestinal flora of the mother is most likely transmitted to the child during childbirth and may lay the foundation for the child's health. One possible solution to ensure an adequate intake may be the consumption of dietary supplements and probiotics. At present, there is insufficient data on supplement consumption among pregnant women. Objective The purpose of the study was to examine how many pregnant women in Västerbotten County chose to consume dietary supplements, mainly iron and probiotics, and whether there was a difference between different factors and intake. Method A quantitative cross-sectional study where pregnant women (n=1473) from the Northpop-study in Västerbotten County responded to a questionnaire regarding consumption of dietary supplements and factors such as age, education, diet etc. The material was analyzed in SPSS with Chi-2-test, independent T-Test and Mann-Whitney U-Test. Using significance level <0.05. Results The majority of participants, 90 percent, responded that they consumed dietary supplements. The factors that increased the intake of dietary supplements in pregnant women were higher age (p=0.030), higher education (p=0.006) and vegetarian/vegan diet (p=0.021). Iron was reported to be consumed by 804 people, 55 percent. The factors that increased the intake of iron supplement in pregnant women were vegetarian/vegan diet (p=0.001). Probiotics were consumed by 25 people, 2 percent. Living in urban areas (p=0.024) and eating vegetarian/vegan diet (p=0.002) increased consumption of probiotics. Conclusion The majority of participants chose to consume some type of dietary supplement, half of the participants consumed iron supplements and a small part consumed probiotics. It appears that pregnant women who are low educated, younger, eating an omnivorous diet and living outside urban areas are in the risk zone for not consuming dietary supplements. / Northpop Pregnant pregnant women woman pregnancy children fetus dietary supplements supplements iron iron supplements probiotics probiotic supplements intestinal flora bacteria gut vitamin vitamins minerals minerals B12 folate diet education low educated highly educated region age intake diet regime northpop Västerbotten Västerbotten County Council Umeå University Umeå Sweden Miriam Lange Bålman Miriam Lange Balman science economist vegetarian vegan mixed diet omnivore urban area country side quantitative nutrition diet dietician dietetics quantitative nutrition diet Chi-2 test independent t-test Mann Whitney U-test Multivitamins (mixture of vitamins) Multi-minerals (blend of minerals) Probiotics Omega-3 fish oil Blutsaft A- vitamin B vitamin vitamin C vitamin D vitamin E folic acid iron calcium beta-carotene vitamin B complex selenium antioxidants zinc magnesium q10 exercise physical activity lifestyle bachelor essay Gravid gravida kvinnor kvinna graviditet foster barn kosttillskott tillskott järn järntillskott probiotika probiotikatillskott tarmflora bakterier tarm vitamin vitaminer mineral mineraler B12 folat kost utbildning lågutbildad högutbildad boenderegion stad landsbygd ålder intag kostregim northpop Västerbotten Västerbottens läns landsting Umeå universitet Umeå Sverige Miriam Lange Bålman Miriam Lange Bålman kostvetenskap kostekonom vegetarisk vegetariskt vegan veganskt blandkost stadsområde kvantitativ näring samhällsrelevans dietist dietetik Chi-2-test oberoende t-test Mann Whitney U-test Multivitaminer (blandning av vitaminer) Multimineraler (blandning av mineraler) Probiotika Omega-3 fiskolja Blutsaft A-vitamin B-vitamin C-vitamin D-vitamin E-vitamin Folsyra Järn Kalcium Betakaroten Vitamin B-komplex Selen Antioxidanter Zink Magnesium Q10 träning fysisk aktivitet livsstil uppsats kandidatexamen Nutrition and Dietetics Näringslära
