Abstract:

<p>Introduktion – Ekonomistyrning innefattar färdigställandet och användandet av finansiell information och det hjälper företagsledare i sitt beslutsfattande. När det sätts i bruk bland människor har det ett dubbelriktat förhållande där systemet och människorna påverkar varandra. När man ser det så är det inte förvånande att många försök att byta styrsystem misslyckas. För att kunna förstå varför en del försök att byta system lyckas och andra misslyckas är det viktigt att veta var motstånd mot förändringar kommer ifrån och hur motståndet verkar. De flesta modeller som behandlar byte av ekonomi

Abstract:

"Barriers to Closure" was a series of narratives specifically focusing on reoccurring thoughts, fears and anxieties within the artist's life. Instilled when he was younger, these anxieties were never resolved, thus creating additional fears as he grew into adolescence. Eventually they transformed into an intricate obstacle causing resolution to be a difficult task.These narratives are presented in thick bronze frames which constrain the content into a limited space. The pieces are purposefully small due to the artist's personal restriction of revealing what needs to be seen. Therefore, the vie

Abstract:

There is a growing body of literature recognizing the benefits of Open Data. However, many potential data providers are unwilling to publish their data and at the same time, data users are often faced with difficulties when attempting to use Open Data in practice. Despite various barriers in using and publishing Open Data still being present, studies which systematically collect and assess these barriers are rare. Based on this observation we present a review on prior literature on barriers and the results of an empirical study aimed at assessing both the users' and publishers' views on obstac

Abstract:

An alternative road traffic noise barrier using an array of periodically arranged vertical cylinders known as a Sonic Crystal (SC) is investigated. As a result of multiple (Bragg) scattering, SCs exhibit a selective sound attenuation in frequency bands called band gaps or stop bands related to the spacing and size of the cylinders. Theoretical studies using Plane Wave Expansion (PWE), Multiple Scattering Theory (MST) and Finite Element Method (FEM) have enabled study of the performance of SC barriers. Strategies for improving the band gaps by employing the intrinsic acoustic properties of the

The primary purpose of this research was to examine a sample of sixteen lesbian women regarding the barriers to lesbian health-care. From this information several interpretive findings regarding lesbian health-care are made. Data were gathered via indepth interviews with each individual lesbian. The data suggest that most lesbian women do not reveal their sexual orientation to their primary-care physician for fear of reprisal. Most of the women interviewed do feel they receive adequate health-care from their physician. The women who participated in this project did so confidentially and were a

Across the world, confirmed by academic and internal research evidence, Government and public sector organisations consistently display varying degrees of difficulty in generating, developing and implementing innovative ideas.

Given this necessity, there is a definite, identified need to critically review the literature covering theory development and innovation practice as part of a cultur

This work undertook the examination of the perceived barriers that exist to the management of occupational noise exposure in the workplace. Exposure to excessive levels of noise results in cumulative damage to the hearing mechanism of the ear and a subsequent hearing loss. This hearing loss is permanent and does not recover over time. Initially the conventional method of addressing or controlling noise exposure was through Hearing Conservation Programs and more recently through Occupational Noise Management Programs that take more of a risk management approach.

One of the most important aspects for all life on this planet is the act to keep their biological processes in a state where they do not reach equilibrium. One part in the upholding of this imbalanced state is the barrier between the cells and their surroundings, created by the cell membrane. Additionally, terrestrial animal life often requires a barrier that protects the organism's body from external hazards and water loss. As an alternative to experiments, the investigation of the processes occurring at these barriers can be performed by using molecular dynamics simulations. Through this met

This has generally been presumed to be due to the passage of nanoparticles to the fetus.
