Mellan ord och värde : En tematisk dokumentanalys av kommunikation och ledarskap i offentlig sektor
No full textMellan ord och värde – En tematisk dokumentanalys av kommunikation och ledarskap inom offentlig sektor, denna studie syftar till att undersöka hur intern kommunikation, delaktighet och medarbetarengagemang beskrivs i styrdokument från en kommunal omsorgsförvaltning. Med hjälp av en tematisk dokumentanalys identifieras återkommande mönster och ideal i dokumentens innehåll, särskilt fokus på värden som delaktighet, tillit och engagemang. Materialet utgörs av tre centrala styrdokument: en kommunikationspolicy, en kommunikationsstrategi samt en verksamhetsplan. Studien utgår från ett teoretiskt ramverk som inkluderar excellenceteorin, hållbart ledarskap, kommunikationskanalteorier samt psykologiska villkor för engagemang. Analysen visar att intern kommunikation framställs som ett strategiskt verktyg för att nå verksamhetsmål, men att konkret vägledning kring praktisk tillämpning ofta saknas. Ideal som dialog, öppenhet och förtroende lyfts fram, särskilt i relationen mellan chef och medarbetare. Studien bidrar med insikter om hur värderingar kommuniceras i text och belyser styrdokumentens roll i att forma ett kommunikativt klimat inom offentlig verksamhet
Drying and Rehydration of Calcium Alginate Gels
No full textIn this paper, we study the rehydration properties of air-dried calcium alginate gel beads. Rehydration is shown to depend on alginate source (i.e. mannuronic to guluronic acid ratio) and the salt concentration in the rehydration medium. Rehydration curves are described adequately by the empirical Weibull equation. Wide-angle X-ray diffraction measurements are performed to obtain information on the microstructure of dried alginate gels. The X-ray diffraction patterns provide evidence for formation of ordered domains in which alginate polymers are laterally associated. Formation of ordered structures during drying is found to have a large impact on rehydration properties. Lateral association of alginate chains is reduced (and rehydration improved) by removing excess calcium ions from the gel beads in a washing step prior to air drying. In addition, rehydration properties of mixed alginate–carboxymethyl cellulose (CMC) gel beads are investigated. The presence of CMC in the gel matrix is found to reduce lateral association of alginate chains during drying and to improve rehydration properties.DelftChemTechApplied Science
Fyysisen jakeluverkoston kehittäminen urheiluinstrumenttiteollisuudessa
No full textToday's fierce competitive environment drives companies to seek competitive advantage from their supply chains. Earlier companies focused on cost reduction, but now the ever changing environment forces companies to increase the responsiveness of their supply chains. Agility and flexibility are today's paradigms towards to more responsive supply chain.
This research studies the design of physical distribution network. This research contains two parts. First part, theoretical is based on supply chain management, physical distribution and performance management. Empirical part applies the knowledge build during the theoretical part in Finnish based sport instrument company. The main research question is "What is the optimal physical distribution network for Case Company?".
Literature part presents a general framework for companies how to analyze their supply chains and products to devise optimal physical distribution networks. To devise the optimal distribution network company has to go through four steps. First is to define the nature of product, second is to decide priorities in the supply chain, third to define a proposal for the optimal distribution network and fourth to use performance measures to define optimal distribution network.
Empirical part analyzed Case Company using the framework that literature review presented. Author conducted the four step analysis presented above in the empirical part. The research approach of thesis was constructive and also principles of the case study approach were applied.
The findings of empirical part show that companies whose products' demand patterns are unpredictable and the supply chain requires agile and flexible performance, deliveries directly to retailers can be lucrative choice when considering physical distribution structure. Depending on the As-Is state of physical distribution there is possibility to shorten total order cycle time and cut inventory levels. Distance to customer is not measured anymore in kilometers, but in time. This research shows that Case Company can be nearer to customer in time when the location of distribution centre is further. Direct delivery is possible to implement without increasing logistics cost. Direct retail deliveries will increase the costs of pollution, because companies need use more airfreight to meet the customer requirements. Direct retail deliveries are more attracting choice when delivering goods from east to west. This is due to time difference between consignor and consignee.Nykypäivän ankara kilpailuympäristö ajaa yritykset etsimään kilpailullisia etuja niiden toimitusketjuista. Aikaisemmin yritykset ovat keskittyneet kulujen minimoimiseen, mutta nykypäivän alati muuttuva kilpailuympäristö pakottaa yritykset hakemaan paremmin asiakaskysyntään vastaavia toimitusketjuja. Ketteryys ja joustavuus ovatkin tämän päivän yleisesti hyväksyttyjä teoriasuuntauksia haettaessa asiakasvastaavuutta toimitusketjuista.
Tässä työssä tutkittiin fyysisen jakeluverkoston suunnittelua. Tutkimus sisältää teoreettisen ja empiirisen osan. Teoreettinen osa luo tietopohjan toimitusketjun johtamisesta, fyysisestä jakelusta ja toiminnan mittauksesta. Empiirinen osio vie teoreettisen osan tiedot käytäntöön. Teoreettisen osan tietoja tutkitaan tapaustutkimuksella eräässä suomalaisessa urheiluinstrumentteja valmistavassa yrityksessä. Päätutkimuskysymys tutkimuksessa oli "Mikä on optimaalinen fyysinen jakeluverkosto tapaustutkimusyritykselle?".
Kirjallisuustutkimus esittelee teoriaa toimitusketjun hallinnasta, fyysisestä jakelusta ja toiminnan mittaamisesta. Teorioiden pohjalta kirjallisuustutkimus esittelee viitekehyksen, jonka avulla yritys voi suunnitella optimaalisen fyysisen jakeluverkoston. Optimaalisen fyysisen jakeluverkoston suunnittelu sisältää neljä vaihetta. Ensimmäiseksi määritetään tuotteen kysynnän luonne, toiseksi tunnistetaan vaatimukset toimitusketjulle, kolmanneksi muodostetaan ehdotus fyysisestä jakeluverkosta ja lopuksi lasketaan mikä on optimaalinen ratkaisu jakeluverkostolle.
Empiirinen osa soveltaa käytäntöön teoreettisen osan viitekehystä. Käytäntöön soveltaminen toteutetaan tapaustutkimuksen muodossa. Kirjoittaja käy läpi kaikki neljä viitekehyksen vaihetta ja muodostaa suosituksen kohdeyritykselle optimaalisesta fyysisestä jakeluverkosta.
Empiirisessä osassa havaittujen tulosten perusteella voidaan sanoa, että yritys, joka toimii jatkuvasti muuttuvassa toimintaympäristössä ja jonka tuotteiden kysyntä on hankalasti ennustettavaa ja elinkaaret ovat lyhyitä, kannattaa harkita suoratoimituksia vähittäiskauppoihin. Suoratoimituksilla yritys voi olla lähempänä asiakasta ajallisesti vaikka fyysisesti olisikin kauempana. Yritykselle on mahdollista saavuttaa parempi asiakaspalvelun taso pienemmillä kustannuksilla ja varastoilla, jos se käyttää suoratoimituksia vähittäismyymälöihin. Suoratoimitusmalli on houkuttelevampi vaihto ehto, kun toimitukset matkaavat idästä länteen. Näin yritys voi hyödyntää aika eron kuljetuksessa
Children in Prostitution: A study of young women in the rehabilitation centres in Malaysia
No full textChild prostitution has been a major cause of concern in recent years. It is a global phenomenon, which has spread widely in both developing and developed countries. In Malaysia, child prostitution does exist, but it is a phenomenon that the public does not really acknowledge or understand. This study is an attempt to investigate the nature of child prostitution in Malaysia and to identify the key characteristics of victimized children to raise awareness of the phenomenon in the public, government, and NGOs. Two methods of data collection were used in this study; that is semi-structured interview and narrative interview. Altogether, 63 young women safeguarded from prostitution in two rehabilitation centres participated in this study as respondents. The findings suggest that the vast majority of prostituted young women in this sample are likely to: have experienced family dysfunction, family breakdown or domestic violence; be emotionally and physically abused during childhood; suffer from family problems and poor relationship with the family; leave school and home at an early age; and be sexually abused or exploited before they were drawn into prostitution. Ninety-two percent of the respondents entered prostitution between the ages of 13 to 17 years old. The youngest was nine years old. About 48 percent were engaged in prostitution after being deceived by 'boyfriends' who really acting as pimps and 38.1 percent were influenced by peers. Most of them 'served' sex to between 6-10 men per day, 'worked' seven days a week, and were abused by pimps and customers. About 83 percent used drugs, most commonly psychotropic pills and marijuana. The vast majority of them did not use any contraception during prostitution. Implications of the findings are discussed and suggestions made for an effective response to the problem and in aiding the young women in prostitution and the rehabilitation centres, as well as for further research
Development of frameworks for steel manufacturing planning capability improvement using discrete event simulation
No full textCustomers of a steel manufacturing company now order a large number of low volume
orders instead of a small number of high volume orders as they would have done just
a few decades ago. The change in customer expectations has complicated production
planning and scheduling within a steel manufacturing company.
The aim of this research is to improve production planning and scheduling capability
in steelmaking using one of the popular simulation techniques, called discrete event
simulation. In this research it is observed that there are three major areas that need
attention to improve production planning and scheduling capability. First, selection of
optimal schedules and plans based on throughput, production time, stock size, and other
production processing criteria. Next, incorporating cost into the criteria to select the
schedules and plans will make the planning more cost effective and realistic at the same
time. In addition, with the increased use of discrete event simulation modelling, there is
a need to improve the model development efficiency and make the process less reliant
on practitioners’ experience and capabilities, in order to improve the overall planning
and scheduling capability. This thesis presents frameworks to address the three major
areas for the capability improvement.
This research adapts a systematic approach to validation. Theoretical, realisation,
and empirical parts of the research were separately validated. Real life case studies
were used for validation of each proposed framework.
Discrete event simulation can improve the accuracy of production planning & scheduling
and cost estimation for complex production systems. GA-based multi-objective optimisation
can be successfully applied to optimisation of plans and schedules. Production
planning and scheduling optimisation for some production areas provides a challenging
problem to GAs. Cost estimation in the steel manufacturing company needs improvement
because of the current lack of accurate costs of product families that affects quality
of price management. The developed cost estimation technique is capable of providing
more realistic cost for product families. The cost estimation technique would be useful
for companies operating on volume-driven manufacturing processes rather than on
unit-driven. Conceptual modelling needs to be improved in order to achievein model
development efficiency and to make the process less reliant on practitioners’ experience
and capabilities. A formal information collection process can aid conceptual modelling
of production systems by further development of DES models for cost estimation
