Foster owner factors influence temperament test results of military dogs and their suitability for service

Military dogs in Sweden spend their first 18 months after weaning with a foster owner that has volunteered to care for its upbringing. The foster owner is advised by a consultant and offered three opportunities to train the dog together with other foster owners. There is a positive correlation between the number of attended training opportunities with the consultant, or other professional dog trainers, and the results of the dog in the temperament test at the end of the 18 months. The test results are in turn positively correlated with the likelihood of the dog to enter service. This thesis aims to investigate why the number of training opportunities is important for the dog?s chance to enter service by identifying foster owner factors that influence the success of the dog and which temperament test items the factors have the strongest impact on.

The genetic background of oxytocin and its importance for maternal behaviour of sows

Oxytocin is today widely spoken of as a "feel good" hormone. Recent research has increased interest in the hormone and its role in social and sexual interactions, as well as its importance for complex behavioral patterns. There is evidence that oxytocin is released during physical contact and is said to suppress anxiety and stress. In animals and humans, oxytocin, which is a neuropeptide and likewise a hormone, is necessary for parturition and lactation. Synthesis of oxytocin occurs in brain neurons and in specific organs involved in reproduction.

Habitat use and ranging behaviour of GPS tracked juvenile golden eagles (Aquila chrysaetos)

Throughout its wide distribution in the northern hemisphere, the golden eagle occurs in a diverse range of environments, e.g., mountainous, forest and open areas. The literature on juvenile golden eagles is limited, and this study provides further knowledge on habitat use and ranging behaviour during the post-fledging period in boreal Sweden. A total of 14 golden eagle juveniles were tagged with GPS transmitters during 2010 and 2011, and nine could be followed during the entire post-fledging period from fledging until migration. The juveniles fledged at the end of July and beginning of August and initiated migration during October and beginning of November. The length of the post-fledging period, until migration started, ranged from 49 to 97 days. During this period, the juveniles? distance from their natal nest and their GPS height increased with time as their flying abilities developed.

Effekter av kön, ålder och region på sjukpenningen i Sverige - en variansanalys

According to TCO (The Swedish Confederation for Professional Employees) the worst threat to the Swedish welfare is that so many people because of bad health and unemployment are not a part of the labour force. If Sweden could make the number of people with health and unemployment problems half the size as today, the GDP would increase with more than five percent. In real money this means 110 billion Swedish kronor a year. According to SCB (Statistics Sweden) the difference between women?s and men?s absence owing to illness should be investigated more closely in order to get at better understanding of the problem.

Är sociala medier mest ett hinder? Ungas lärande i sociala medier

A large part of the daily life today means being active online and to take part in the interactions that occur there. The accessibility which social media brings, means that you can reach and be reached in several ways and there are many different ways in which information can be disseminated. Social media supports the learning process. The aim of this study is to examine how upper secondary schools students' use of social media and how it can be used as a tool for informal learning. Our study is based on the socio-cultural perspective where interaction and social cohesion is a big part.

Foraging and anti-predation behavior of Thomson?s gazelles (Gazella thomsoni) and Grant?s gazelles (Gazella granti) at a waterhole

Prey species make behavioral decisions to reduce the perceived risk of predation and the time spent vulnerable to predation. Behavioral responses to predators are for example selection of specific habitat types and the presence of predators influence individual vigilance. Furthermore, there is a variation in feeding niches with different herbivores focusing their foraging effort on different vegetation types which is also expected to affect the choice of habitat. Behavioral data on anti-predation and foraging behavior at on waterhole is collected from Thomson?s and Grant?s gazelles at Ol Pejeta Conservancy (0°00?N, 36°56?E) located in semiarid bushed grassland in Laikipia district of central Kenya.

How to build a rein tension meter

A large part of the interactions between horse and rider during horseback riding takes place through the reins and the bit and devices for measuring the tension on the reins, rein tension meters, has fairly recently been developed. To safeguard the welfare of the ridden horse riders need to be aware of the rein tension they apply and actively work to decrease it. Furthermore, there is a need to develop the study of rein tension through new techniques and refined analysis procedures. A good-quality rein tension meter should be small in size, sensitive, durable and as accurate for light rein tension as for strong forces. Rein tension meters used in research on horse and rider interaction commonly depend on strain gauge technique for generating rein tension data.

Att göra tillit : Hur tillit skapas i interaktionen mellan människor

The purpose of this essay is to examine the origin of generalized trust. We compare existing theories on trust to determine what approach is more fruitful in explaining the prevalence, or absence, of trust. Our conviction is that trust should be viewed as an interaction, rather than a disposition or a rational choice. The sample is based on the countries of the OECD. In total, five different hypotheses are tested: i) that generalized trust is created by equal distribution of income, ii) that generalized trust is created through monitoring of the state, iii) that generalized trust is created through rule by law; iv) that generalized trust is created when the welfare apparatus is guided by principles of universalism; or iv) that generalized trust is created when the state integrates trust networks.

Örter som fodertillskott till häst : populärt komplement utan risker?

In the Swedish market, there is a wide selection of herbs as supplement to the horse´s feed. A trend today is that many companies are marketing herbal remedies with allegations of medical effects. If you want to sell the product for that purpose it must be verified and approved as drug or natural remedy by the Medical Products Agency. Some herbs may contain active substances. Nevertheless, only a few studies have been conducted on single herbs to investigate safe doses for horses.

Den Digitala Identiteten : En kvalitativ studie om identitetskonstruktion på internet

The purpose of this paper is to increase knowledge and understanding of how an identity is constructed on the internet and if it is different from the everyday identity. To analyze this, I have studied the theories of how identity is constructed in everyday life and then applied this on the empirical data that I have collected. In this study, I have chosen to pursue a qualitative approach using semi-structured interviews to gather the empirical data. In the study, six informants participated and all of them has an active social life both on and off the internet. The results that I have found in this study shows that an identity online is constructed in a similar way as it does in real life, however, some limitations that exist in everyday life do not exist online.

Den trådlösa massan - svärmbeteende och kollektiv handling

This essay seeks to analyze the consequences of modern information and communication technology for collective action within the framework of social movements. With references to the protests in Seattle 1999, the essay argues that the emergence of distributed collective action is closely related to the use of technology, for example cell phones and Internet. This distributed collective action can be characterized by its decentralized and self-organizing features, forming a global pattern emerging from local interactions. Whereas contemporary theories of collective action can be ´stretched´ to fit these aspects, they lack analytical tools to describe and analyze such systems. Further, their rejection of classical crowd theory is problematic, since it contains valuable insights.

Barns röster i vårdnadsutredningar : Barn som talar eller omtalade barn?

There is an ongoing discussion in Sweden about child perspective and child?s perspective.The municipalities? family law units are required to include these perspectives in their investigations. But how do they affect the outcome of custody investigations? This essay addresses that issue. I have looked at how much say children have and how much they participate in their custody investigations.

Samspelet mellan kund och konsult i förändringsprojekt - en studie av kommunikationens utmaningar i implementationsprocessen av en ny webblösning

The increasing competition is making increasing demands of today's businesses to be changeable. Change projects have therefore become increasingly common in order to satisfy market expectations. These projects have often proved difficult to implement and fail rather than succeed. There are many people who reflect on why this is and theorists are increasingly reasoning about the importance of communication in the change process. This is something that has given rise to a new area of expertise called change management.

Rörelsens generativa kraft : Den kroppsliga rörelsen som varseblivningens möjlighetsbetingelse

The standard model concerning the relationship between perception and motility is linear and one-way. It depicts the flow between the two as moving from sensation to perception to representation to computation, and finally, to motility and action. According to this model, animal being is basically a bundle of reflexes. But what can correctly be considered a bundle of reflexes from a natural science point of view, doesn't necessarily have to be true. This conception does not take into consideration the more complex interactions between motility and perception that constitutes, or generates, animal and human beings.

Fysikdiskursen på Komvux : Betydelsen av student-lärarinteraktioner

This study draws upon the framework for analyzing the discourse of a science classroom introduced by Mortimer and Scott (2003). It has been used for many studies before on high school youths, but never on adults. Therefore, this study focuses on the interaction between teacher and students in an adult education on high school level in physics, and how students can change the classroom discourse. Observations took place in two different schools for adults, in four different teaching groups. The result was analyzed by pattern of interactions, communicative approach, teaching purpose, type of student questions and their effect on the classroom discourse.
