Partnervåld – en arbetsgivarfråga? : Kommunala enhetschefers uppfattning om arbetsgivarens roll och ansvar i anställdas utsatthet för partnervåld / Partnerviolence – an employer issue?Tångring, Sara, Åkerlund, Fanny January 2020 (has links)
Att vara utsatt för partnervåld kan medföra konsekvenser för både den fysiska och psykiska hälsan, och även att innebära att påverkas på olika sätt. Syftet med studien var att få en fördjupad förståelse kring kommunala enhetschefers uppfattning om sin roll och om arbetsgivaransvar när det gäller anställdas utsatthet för partnervåld. En kombination av kvantitativ och kvalitativ metod har använts och data samlades in genom en webbenkät och semistrukturerade intervjuer som analyserades i deskriptiv, bivariat respektive tematisk analys. Studien visade att partnervåld upplevs av enhetschefer som ett svårt ämne och att avsaknaden av reglering i lagstiftning och fastställda rutiner kring hur dessa ärenden ska hanteras gör att det blir upp till varje enskild enhetschef att avgöra hur det hanteras. Resultatet har sedan diskuterats i förhållande till tidigare forskning, lagstiftning och systemteori. / Being subjected to partner violence can have consequences for both physical and mental health, and also to be affected in different ways. The purpose of the study was to gain a deeper understanding of municipal unit managers 'perceptions of their role and of employer responsibility regarding employees' exposure to partner violence. A combination of quantitative and qualitative method has been used and data were collected through a web survey and semi-structured interviews which were analyzed in descriptive, bivariate and thematic analysis. The study showed that partner violence is perceived by unit heads as a difficult subject and that the lack of regulation in legislation and established routines around how these matters are to be handled, makes it up to each individual unit manager to decide how it is handled. The results have since been discussed in relation to previous research, legislation and system theory.

Previous issue date: 2018-03-12 / This research aims to analyze the losses occurring in the production process of a food
industry, where statistical methods were used in the milk, peanut and marmalade
production line. The case study was carried out at the Doçaria Dois Irmãos, located in
Anápolis state of Goiás, where all the data were obtained for the study. The Toyota
Production System was used with some quality management tools for the identification
and treatment of losses. The data were processed according to the Statistical Process
Control, where the stability tests were performed in the production process stages, and
this was done through the control charts. After stabilizing the production process with the
interventions made in the industry, it was also possible to perform the process capability
test, where it was verified that some process steps do not have capacity. Through the
results obtained, it was also possible to measure financially the losses that were occurring
in the industry, the inherent gains of the investments in the improvement actions and the
time of return on the investment made. Thus, it was understood that the time of return on
investments justifies the interventions in the productive process of the company in
question. It was concluded, therefore, that the losses in the productive process of the
industry under study, not only left the processes unstable and incapable statistically, but
also was generating unnecessary production costs. By applying improvement actions in
the industry, it was possible to raise important information within the production process,
as well as increase the profit in the production line of the selected sweets, due to the
reduction of losses in the process. / Esta pesquisa visa analisar as perdas ocorrentes no processo produtivo de uma indústria
de alimentos, onde foi utilizado métodos estatísticos na linha de produção dos doces de
leite, amendoim e casadinho. O estudo de caso ocorreu na Doçaria Dois Irmãos,
localizada em Anápolis estado de Goiás, onde obteve-se todos os dados para a
concretização do estudo. Foi utilizado o Sistema Toyota de Produção com algumas
ferramentas da gestão da qualidade para identificação e tratamento das perdas. Os dados
foram tratados segundo o Controle Estatístico de Processo, onde se realizou os testes de
estabilidade nas etapas do processo produtivo, sendo isto realizado através das cartas de
controle. Após se estabilizar o processo produtivo com as intervenções feitas na indústria,
foi possível também realizar o teste de capacidade do processo, onde se verificou que
algumas etapas do processo não possuem capacidade. Através dos resultados obtidos, foi
ainda possível mensurar financeiramente as perdas que vinham ocorrendo na indústria,
os ganhos inerentes dos investimentos nas ações de melhoria e o tempo de retorno sobre
o investimento realizado. Sendo assim, entendeu-se que o tempo de retorno sobre os
investimentos justifica as intervenções no processo produtivo da empresa em questão.
Conclui-se, portanto, que as perdas no processo produtivo da indústria em estudo, não só
deixavam os processos instáveis e incapazes estatisticamente, como também estava
gerando custos de produção desnecessários. Ao se aplicar ações de melhoria na indústria,
foi possível levantar importantes informações dentro do processo produtivo, bem como
aumentar o lucro na linha de produção dos doces selecionados, devido à redução de perdas
no processo.

A reliability model of a power distribution network with reference to petrochemical and gas-to-liquid plantsManning, James January 2013 (has links)
The interruption cost for one hour of a petrochemical plant is 33 times higher than that of
the average interruption cost for industrial plants across all industries. In addition to the
high cost of loss of production, interruptions to the operations of petrochemical and gas-toliquid
plants pose safety and environmental hazards. Thus it is necessary to better
understand the reliability requirements of petrochemical and gas-to-liquid plants.
This study investigated the reliability of electrical distribution networks used in
petrochemical and gas-to-liquid plants compared to those used in other industrial plants. A
model was developed that can be used to establish the adequacy of the reliability of a
distribution network in terms of the components and network topologies used. This model
was validated against data that had been collected by the IEEE and applied to an actual
petrochemical plant.
Over 19 years’ worth of data regarding the trips that have occurred on the distribution
network of an existing petrochemical plant was collected and manipulated in order to
calculate the reliability indices associated with the equipment used to make up thisRecommended Practice for the Design of Reliable Industrial and Commercial Power
Systems.
The cost of loss of production and the capital costs associated with increased reliability
were calculated for a section of the existing petrochemical plant. The reliability associated
with different network topologies that could possibly be used to supply power to this
section of the plant were modelled using an appropriate software package. The resulting
total cost of ownership over the life of the plant associated with each topology was then
calculated in order to establish which network topology is the most appropriate for
petrochemical and gas-to-liquid plants.
It was concluded the components that affect the reliability of an industrial distribution
network are different to those that affect a utility distribution network. These components
were listed and compared. It was found that the reliability indices that were calculated for
the components that affect the reliability of a petrochemical plant were similar to those
provided by the IEEE. 17 out of 20 of the indices that were calculated were within the
required factor of deviation. Generally the failure rates of components used in
petrochemical plants were very similar to those given in the IEEE Gold Book, while the
MTTR’s for the components used in petrochemical plants were found to be slightly better
than those given in the IEEE Gold Book. The effect of network topology was found to be significant, with small changes in the
topology of a network resulting in large variations in the reliability of the network. It was
also found that the most appropriate type of network topology to use in the design of the
electrical distribution network of a petrochemical plant is the dual radial network. This is
the most conservative of the commonly used network topologies and is the one that is
currently used in the existing plant that was studied.
Due to the high cost of loss of production in petrochemical plants it was established that
any incremental improvement in the reliability of the dual radial network would be
beneficial to the total cost of ownership of such a plant. Such incremental improvement of
the reliability of the distribution network could be cost effectively achieved by adopting a
conservative maintenance strategy and the establishment of a conservative spares
inventory. Before this study was undertaken, there was no literature around the reliability of electrical
distribution networks that focused specifically on petrochemical and gas-to-liquid plants.
This study produced a set of reliability indices and a model that electrical engineers can
use in the reliability analysis of petrochemical and gas-to-liquid plants. Furthermore it
shows that, because the cost of loss of production in petrochemical plants is so high, the
most conservative distribution network design and maintenance philosophies should
always be used.
