Yrityksen toiminnan tehostaminen tilaus-toimitusprosessia kehittämällä

Tämän tutkimuksen päätavoitteena on selvittää, miten tilaus-toimitusprosessia kehittämällä voi tehostaa yrityksen toimintaa. Tutkimuksen alatavoitteina ovat tilaus-toimitusprosessin merkitystä ja kehittämistä koskevat kysymykset. Lisäksi tutkimuksessa selvitetään, voivatko tilaus-toimitusprosessi ja logistinen osaaminen olla kilpailuedun perustana. Työn näkökulma on asiakasnäkökulma. Tutkimuksessa on piirteitä toiminta-analyyttisestä ja konstruktiivisesta tutkimuksesta. Tutkimuksen viitekehys rakentuu tilaus-toimitusprosessin kehittämisen ja kilpailuedun muodostumisen kautta. Tilaus-toimitusprosessin kehittämiseksi tutkimuksessa paneudutaan prosessin kehittämisen yleisen mallin ja ABC-analyysin teorioiden kautta. Lopuksi tutkimuksessa etsitään vastaukset, voiko tilaus-toimitusprosessi olla kilpailuedun perusta. Aiempien tutkimuksien avulla selvitetään, millaisia hyötyjä logistisen prosessin avulla muodostetusta kilpailuedusta on yrityksen muihin osa-alueisiin. Tutkimuksen case-yrityksen, valmistavan teollisuusyrityksen, tilaus-toimitusprosessi on kehityskohde. Case-yrityksen tilaus-toimitusprosessia tarkastellaan yleisen prosessin kehittämisen mallin ja ABC-analyysin teorioiden kautta. Työn tulokset osoittavat, että kehittämällä tilaus-toimitusprosessia voidaan tehostaa yrityksen toimintaa. Tilaus-toimitusprosessin asiakasrajapinnan vuoksi hyvin onnistunut tilaus-toimitusprosessi vaikuttaa asiakastyytyväisyyteen. Tutkitut kehitysmallit vaikuttavat positiivisesti tilaus-toimitusprosessin onnistumiseen. Tilaus-toimitusprosessin positiivinen vaikutus kilpailuedun muodostumiseen osoitetaan myös tutkimuksessa.

Orkesterityön haasteet : ihanteellinen orkesterikoulutus jousisoittajan näkökulmasta

Opinnäytetyössä käsitellään orkesterisoittoa ja sen koulutusta sekä ammattilaisten että opiskelijoiden näkökulmien pohjalta. Varsinkin käytännön orkesterityöstä kertovat luvut tarjoavat ajankohtaista tietoa orkesterityön haasteista ja vaatimuksista sekä tuleville muusikoille että muille asiasta kiinnostuneille. Tämän lisäksi työ on kohdistettu orkesterikoulutuksen parissa työskenteleville henkilöille. Työ perustuu kahden orkesterimuusikon ja kahden kapellimestarin asiantuntijahaastatteluihin sekä aiheesta kirjoitettuihin artikkeleihin ja opinnäytetöihin. Punaisena lankana työssä on orkesterikoulutuksen kehittämisen tarve. Vastavalmistuneelle opiskelijalle on suuri haaste selvitä ensimmäisistä vuosista ammattiorkesterissa, jossa vallitsee nopea työtahti, mikäli orkesterityöskentelyyn ei ole valmistautunut monipuolisesti jo ammattiopintojen aikana. Työn tarkoituksena on esittää ehdotuksia ja ideoita orkesterikoulutuksen kehittämiseksi ja herättää keskustelua orkesterikoulutuksesta. Työ luo näin siltaa orkesterisoiton ammattiopintojen ja työelämän välille.

On Transmission System Design for Wireless Broadcasting

This thesis considers aspects related to the design and standardisation of transmission systems for wireless broadcasting, comprising terrestrial and mobile reception. The purpose is to identify which factors influence the technical decisions and what issues could be better considered in the design process in order to assess different use cases, service scenarios and end-user quality. Further, the necessity of cross-layer optimisation for efficient data transmission is emphasised and means to take this into consideration are suggested. The work is mainly related terrestrial and mobile digital video broadcasting systems but many of the findings can be generalised also to other transmission systems and design processes. The work has led to three main conclusions. First, it is discovered that there are no sufficiently accurate error criteria for measuring the subjective perceived audiovisual quality that could be utilised in transmission system design. Means for designing new error criteria for mobile TV (television) services are suggested and similar work related to other services is recommended. Second, it is suggested that in addition to commercial requirements there should be technical requirements setting the frame work for the design process of a new transmission system. The technical requirements should include the assessed reception conditions, technical quality of service and service functionalities. Reception conditions comprise radio channel models, receiver types and antenna types. Technical quality of service consists of bandwidth, timeliness and reliability. Of these, the thesis focuses on radio channel models and errorcriteria (reliability) as two of the most important design challenges and provides means to optimise transmission parameters based on these. Third, the thesis argues that the most favourable development for wireless broadcasting would be a single system suitable for all scenarios of wireless broadcasting. It is claimed that there are no major technical obstacles to achieve this and that the recently published second generation digital terrestrial television broadcasting system provides a good basis. The challenges and opportunities of a universal wireless broadcasting system are discussed mainly from technical but briefly also from commercial and regulatory aspect

Distribuição de metais e caracterização das constantes de troca entre espécies metálicas e frações húmicas aquáticas de diferentes tamanhos moleculares

In this work the metal distribution and exchange constants between metal species and aquatic humic fractions with different molecular sizes were studied. The aquatic humic substances (AHS) were extracted by XAD-8 resin from water sample collected from Itapitanguí river, São Paulo State, Brazil. The AHS were fractionated in six fractions with different molecular sizes (>100 - <5 kDa) and characterized by several techniques. Molar ratios H/C suggested higher aromaticity for fractions F1 and F6 whereas molar ratios C/N didn´t show any differences regarding the humification degree between the fractions. The UV-Vis absorbance a254/a436 ratio showed higher results for F4 and F5, probably by less condensed features. FTIR studies showed high similarity in the functional groups in the fractions. The highest percentage of traces of Co, Al, Fe, Mn, Cu, Zn and Ni (determined by ICP-AES) was preferably complexed by fractions F3 and F4 with a greater amount of dissolved organic carbon (DOC). In addition, the exchange constants, determined by ultrafiltration method, showed complexes AHS-Fe and AHS-Al with higher stability than complexes AHS-Co in all fractions.

Extração de matéria orgânica aquática por abaixamento de temperatura: uma metodologia alternativa para manter a identidade da amostra

In this work was developed an alternative methodology to separation of aquatic organic matter (AOM) present in natural river waters. The process is based in temperature decreasing of the aqueous sample under controlled conditions that provoke the freezing of the sample and separation of the dark extract, not frozen and rich in organic matter. The results showed that speed of temperature decreasing exerts strongly influence in relative recovery of organic carbon, enrichment and time separation of the organic matter present in water samples. Elemental composition, infrared spectra and thermal analysis results showed that the alternative methodology is less aggressive possible in the attempt of maintaining the integrity of the sample.

Los trastornos del comportamiento alimentario y las ciencias: una mirada a las revistas científicas

La publicación de artículos científicos que tratan los trastornos del comportamiento alimentario (TCA) se ha incrementado en los últimos años y han experimentado un aumento significativo que puede ser atribuido a diferentes factores, entre ellos el surgimiento de nuevas publicaciones más selectivas y especializadas. La creciente investigación examina las preocupaciones de la imagen corporal y otras conductas asociadas, además de realizar investigaciones con diversos grupos poblacionales que incluyen a hispanos, asiáticos, europeos, etc. Este trabajo, muestra una revisión realizada a 136 artículos publicados en 67 revistas de ámbito internacional. Los artículos comprenden una selección realizada entre el año 2004 y el año 2008, como fruto de una revisión bibliográfica que sirvió de base para el desarro-llo del proyecto I+D denominado “La Publicidad de TV entre otros factores socioculturales influyentes en los TCA, estudio experimental y panel de expertos internacional” (2006-2010), proyecto del cual las autoras forman parte. En el artículo se concluye que existe una amplia tendencia a examinar los medios de comunicación y su influencia en los TCA y que las muestras tienden a utilizar a mujeres en su mayoría jóvenes, las cuales presentan un mayor grado de incidencia hacia los trastornos alimentarios que los hombres jóvenes. Se observó además que los investigadores detectan la sintomatología en grupos con una edad cada vez menor.

Developing an Improved System for Allocating Support Unit Costs to Business Units

The objective of this study is to develop an improved support unit cost allocation system for a medium-sized technology company, and to examine which options for overhead cost accounting exist. The study begins with presenting the terminology and methods associated with overhead cost accounting and responsibility accounting. Also the most common challenges and resulting benefits of overhead cost allocation system development are brought up. As one research method two case studies were conducted for benchmarking purposes. These external cases are compared with the principal company’s cost allocation system and reflected against the theoretical background. In the empirical section interviews were used as the primary source of information alongside self studying principal company’s old cost allocation method. Interviews revealed the main weaknesses of the old system and proposals for a new one, which were utilized in setting targets for developing the new system. As a result of the development process an improved support unit cost allocation system was realized for year 2009. The new system is able to handle support unit costs in more detail enhancing the transparency and fairness of resulting cost allocations. Parts of support unit costs are now seen as business units’ own costs rather than group-level overhead. Also recommendations for further development are made after analyzing how well the targets were reached.

The Influence of the media and advertising on eating disorders

This article describes a literature review of the influence of advertising and the media on Eating Disorders (ED). Research published in scientific journals in various fields of social sciences such as sychology, psychiatry and communication science has enabled us to conclude that the content displayed in the media, including advertising, are enhancers of disorders and contribute significantly to body issatisfaction in relation to the perceived idea of beauty, it also facilitates the development of weight loss strategies in women and gain of muscle mass in men.

Consumo y convergencia mediática de la prensa local en Cataluña

Los nuevos hábitos de consumo de medios en el marco de la convergencia digital están propiciando un cambio en las estrategias de los medios de comunicación. Mientras unos usuarios siguen prefiriendo la radio, la televisión y la prensa tradicional para informarse otros participan de la experiencia digital en internet (blogs, redes sociales...) y dispositivos móviles, etc. En este panorama es complicado precisar dónde nace y termina el contenido o hasta qué punto es la participación del usuario quien (re) construye la información; así los contenidos mutan y se diluyen en varios soportes. En este contexto, la prensa local también vive las consecuencias del nuevo paradigma y asume los retos del reacomodo del sector ante la nueva realidad. Esta comunicación presenta las conclusiones del estudio cualitativo con entrevistas en profundidad a los responsables de medios locales en Cataluña sobre sus usuarios, contenidos y soportes en el marco de la convergencia digital.

Convergència mediàtica digital: el consum de continguts i l'ús de nous mitjans per dones a Catalunya

Des de fa 20 anys, el sector audiovisual viu una important transformació, tant de l’oferta com del consum, en el marc de la convergència digital. La convergència anuncia la coexistència dels nous mitjans digitals amb l’apogeu d’una cultura participativa, protagonitzada per comunitats d’usuaris amb una activitat quasi frenètica (Jenkins,2008). Noves modalitats de treball cooperatiu que permeten la creació i recreació grupal de continguts, i la creació de comunitats d’usuaris que utilitzen i reutilitzen les noves modalitats de serveis. En aquest context, augmenta la segmentació, la fragmentació i l’abonament dels usuaris (Tous, 2009), perquè la tipologia de les plataformes de continguts ha variat de manera significativa, s’han incorporat els dispositius mòbils i s’han diversificat i sofisticat les ofertes a Internet.
