Barnskötare eller förskollärare : Är det egentligen någon skillnad?
My purpose with this essay was to study if there was any difference in competence between preschool teachers and child minders at a preschool outside of Stockholm. To determine what the differences consisted of, if there was any. The questions I wanted answered were as follows: Are there any differences in competence between preschool teachers and child minders? Do the two different occupations have different ways at looking at what the children need and their abilities? Do they see that they have different skills depending on what occupation they belong to? What do they believe that the people from the other occupation contribute to the preschool which compliments their own working skills?I used a qualitative method which included interviews and observations to find out the answers to these questions. My results from these interviews and observations indicated that experience, personality and attitudes are very important as well as education.
Överlevnad och tillväxt för nyplantersade barrots- och täckrotsplantor : en studie av 42 bestånd i södra Sverige
The choice between bare-rooted and containerized seedlings in southern Sweden affects
the investment costs as well as growth and survival. It is important to take these differences
into account when choosing seedling type for reforestation. The most important
differences between the two seedling-types is that bare-rooted seedlings has open root
systems whereas the roots of containerized seedlings are grown in a container which may
contain water and nutrients that are available for the seedling during the first period after
planting. Moreover, bare-rooted seedlings are often older which results in thicker stembase
and better resistance to attacks of pine-weevil (Hylobius abietis).
In order to study differences in survival and growth between bare-rooted and containerized
seedlings a survey study of newly planted clearcuts in south-western Sweden was
made. In the study tree seedling types was included, one bare-rooted and two containerized
with different ages.
The population of pine weevils was probably low during the studied period which
resulted in lower pine-weevil damage than normally found in this area.
- Ni får gärna hoppa på golvet om ni vill hoppa : En studie om pedagogers bemötande av barns egna initativ i förskola och förskoleklass
The purpose of this survey was to discern possible similarities and difference between how teachers in preschool and pre-class respond to children?s own initiative out of a power perspective. The results of this study is collect by observations that we have done in free and planned activity in both preschool and pre-class as well as a few interviews with some of the teachers. The results have shown that teacher?s responses to children?s own initiatives in preschool and pre-class to most part is similar, despite the difference in their commission.
Subkultur och kommunikation : påverkar olika kulturer den hierarkiska kommunikationen i en organisation?
The essay studies the relationship between communication and organizational culture; to determine if there are any cultural differences between the management of an organization and its employees and to examine how a difference can affect the communication of organizational policies. A case study, where the public school was examined, was used to answer the research question, and interviews were held with relevant people on different levels in the organization.The interviews were analyzed with the theoretical frame of reference as a benchmark. Cultural differences could be identified between different levels in the organization and between the two schools studied. The differences affected how and why people communicated but not how well the respondents understood each other.Keywords: Organizational culture, subculture, Organizational communication, affects, hierarchy..
Sex differences in feeding visit rates in Northern Wheatears Oenanthe oenanthe
AbstractThe Northern Wheatear (Oenanthe oenanthe) is a small insectivorous passerine bird living in open landscapes. Both parents feed the brood of approximately five chicks, but little is known about how each sex allocates their feeding effort. In this study I investigate feeding nest visit differences between male and female Northern Wheatears relative to the age of the chicks, the number of chicks and the quality of the territory for 17 pairs from 2008-2010. Data were collected using automated data loggers to record nest visitation rates during chick feeding, and the sex was determined from nest video cameras. I also examine if the parents? rate of feeding visits changes over the nestling period.
Attityder kring våldtäktsmän : skillnader i utbildningsval, kön och ålder?
The aim of the study is to investigate attitudes about rapists and to determine whether it is felt that they need treatment, imprisonment or a combination of the two. The study examines differences in attitudes between two different educational groups. The first group of students is comprised of those studying on programs that lead to careers working with people, whilst the other contains students who will work in business administration. The investigation also includes views on which punishment alternative the informants believed to be the most appropriate. The same differences are also investigated between gender and age.
Tonala skillnader mellan en traditionell och en modern gitarrkonstruktion : En jämförelse mellan två klassiska gitarrer
During my studies to become a guitar builder at Carl Malmsten CTD, I have found an interest in the construction of the classical guitar. I am fascinated by the simplicity of its construction. A simplicity that becomes more complex when you start to study it in detail.In my final thesis I will not try to explain this complexity. The subject is to investigate two different principles regarding its construction. I would like to find out if the sayings concerning one of the principles will yield a guitar with greater ability to produce volume and projection.At a close distance the difference between the guitar?s volumes is not to speak of, but a significant difference can be seen regarding one of the guitars ability to project its sound.
Undersökning av artikulation, nasalitet och förståelighet hos 16- och 19-åringar födda med isolerad gomspalt
This study highlights the differences in articulation, nasality and intelligibility between twenty 16-year-olds and thirteen 19-year-olds born with isolated cleft palate and control groups. The test groups are compared in a longitudinal perspective and based on earlier evaluations of velopharyngeal impairment. Significant differences were found between test groups and control groups using quantitative comparisons based on SVenskt Artikulations- och Nasalitets-TEst and NasometerTM. The longitudinal comparison also showed a positive but not significant development of the speech. Differences emerged in the comparisons based on velopharyngeal impairment but no significance analysis was made.
Dårarnas slott : en undersökning av patientrullar på Stockholms hospital
Teaching preschool children about the environment. A comparative study of how two preschools work with environmental issues.My investigations are based on qualitative interviews and observations carried out at two preschools, one of which has a nature and environment profile while the other works in traditional ways with these questions. I sought to explore the ways in which pedagogues in each preschool raise environmental awareness and, more generally, awaken an interest in nature in the children. The consequences of methodological similarities and differences will be considered.This term paper concludes that the difference between an environmental profile preschool and a traditional preschool working on environmental awareness is not large. The knowledge gained by children in the latter preschool surpassed that gained in the former.
Utveckling och utvördering av statistiska metoder för att öka träffsäkerheten hos lokala vindprognoser
Wind is used as an energy source all over the world. To be able to use this effectively, there is a need for as good forecasts and forecast models as possible. One of these models is Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS®) that is used to calculate short time forecasts. This model is used here to calculate wind speeds at two different areas in Västra Götaland, Bengtsfors and Vänersborg. There are also wind measurements with SODAR stations for these areas.
Könsskillnader i upplevelse och användande av socialt stöd på arbetsplatsen
This study examines gender differences in the perception and utilization of social support in traditional female- and male workplaces. This study confirms results from earlier studies which suggest that there are gender differences. The survey instrument measures four types of social support: informational, instrumental, appraisal and emotional among 314 working women and men. Women report higher levels of social support on all four types. There is a significant difference in instrumental support between women working in female dominated workplaces compared to men working in male-dominated workplaces and between some of the trades.
Padre versus Pappa - en kvalitativ komparativ studie om mäns erfarenheter och attityder till faderskapet i Spanien och Sverige
Different institutional and culture contexts are argued to create differences in fathers practices and attitudes toward fatherhood. By in-depth interviews with swedish and spanish fathers, this Bachelor thesis aims to describe fathers experiences and attitudes toward fatherhood and how they relate to the institutional and culture context. The selection of swedish and spanish fathers aims to illustrate differences and similarities in two welfaremodels that differ. The main difference was how social policy provoces differences in the distribution between paid and non-paid work, where the spanish fathers remain as the main breadwinner. Differences also appeared in attitudes toward formal care.
Manligt och kvinnligt ledarskap inom byggbranschen : Skillnader och likheter mellan manliga och kvinnliga egenskaper i en mansdominerad bransch
In the construction industry the number of female managers is very low, only four percent (SCB, 2010). In fact, women with management positions has risen by six percentage overall, the last seven years (SCB, 2010). If women in managerial positions continue to grow at this rate, the proportion of women managers will be equal to that of male managers in 2033. More women are needed in the maledominated construction industry in particular because it is deemed that they have a different way of thinking and acting (Granér, 1994). Nelton (1991) believes that companies can take advantage of female managers to be more competitive on the market, the reason why is because women can see other possibilities when solving problems. Rapacioli (2010) argues that the recruitment of women into management positions not only benefits the individual itself but also the company. We have used a qualitative study with a deductive approach. Six respondents from the same company were interviewed, two of them have management positions and the other four were underemployed.The research question of this paper is: What differences and similarities are seen between male and female leadership in terms of their characteristics in the construction industry?The purpose of this paper is to examine similarities and differences in leadership in the construction industry where the focus is on the female and male characteristics. To fulfill our purpose we chose a qualitative study. We have interviewed six respondents at one company in the construction industry. Two of the six respondents have management positions and the remaining four are employed. In this paper we have concluded that there are some differences and similarities between men and women´s leadership in terms of their characteristics.
Jämförelse av vertikala krafter mellan hov och underlag vid nedsittning och lättridning i trav hos häst :
Equestrian sports and the interest in horses have existed for hundreds of years. It is only in the last thirty years the technological development have enabled closer studies of equine locomotion. The production of both soft- and hardware that manages to capture and analyze the fast movement of the horse has resulted in a large increase in locomotion research.
Even though the interest in horses and the different disciplines they compete in is great, there is a small understanding in how the rider influences the movement of the horse in different types of training.
There are several studies available where horses moving freely without the influence of a rider have been studied. What happens with locomotion and ground reaction forces when a rider and equipment are added is not well studied.
The objective of this study was to investigate if there are any differences in the ground reaction forces between sitting and rising trot.
The study contained seven horses. Six Grand Prix dressage horses and one dressage horse competing at intermediate level.
Värdering av tillgångar : En branschpraxis för klädbranschen och byggbranschen
The valuation of an asset is one of the most important thing with accounting, though one of the most difficult thing as well. However, in deciding useful service life for an intangible asset and property, plant and equipment, there are quite a margin for the companies, which creates a difference between companies and industries. When computing the value of the inventories there are a few possibilities available for the companies, which also can generate differencesbetween companies and industries. Although these differences can occur, there might be some similarities in the companies? estimates.
