Kansallisen energia- ja ilmastopolitiikan toteuttaminen puolustushallinnossa

Tässä diplomityössä selvitetään kansallisen energia- ja ilmastopolitiikan toteuttamiseen vaikuttavia tekijöitä puolustushallinnossa. Tavoitteena on tunnistaa, minkälaisia haasteita ja edellytyksiä toteuttamiseen liittyy ja minkälaisia toimenpiteitä ja päätöksiä politiikan toteuttaminen hallinnossa edellyttää. Tutkimuskysymyksiä lähestytään strategiakirjallisuuden, olemassa olevan tutkimustiedon sekä kvalitatiivisen haastattelututkimuksen kautta. Tutkimuksen tarkoitus on edesauttaa hallinnon oman energia- ja ilmastostrategian laadintaa sekä toimia johdon työkaluna toteuttamispäätösten tekemisessä. Merkittävimmiksi toteuttamiseen vaikuttaviksi tekijöiksi tunnistettiin resursointikysymykset, johdon sitoutuminen sekä puolustustoimialan erityispiirteet. Lisäksi vaikutuksia tunnistettiin olevan muun muassa kiinteistö- ja energiasopimusjärjestelyillä, asenteilla sekä puolustusvoimauudistuksella. Kirjallisuuskatsauksen teoreettisille käsitteille löydettiin pitkälti vastineet empiirisestä tutkimuksesta, mutta osa haasteista nousi esiin nimenomaan puolustushallinnon toimintaympäristöstä. Osa tuloksista on yleistettävissä laajemmin energia- ja ilmastotoimenpiteille, valtiosektorille ja muille toimialoille. Saatujen tulosten perusteella on mahdollista määrittää reunaehdot hallinnonalan oman energia- ja ilmasto-ohjelman laadinnalle sekä ennakoida toteuttamisedellytyksiä. Ohjelman toteuttamista tukevina jatkotoimenpide-ehdotuksina esitetään yhteistyöverkoston yhteistä julkista sitoutumista energia- ja ilmastopolitiikan edistämiseen, konkreettisten toimintaohjelmien laatimista sekä tietoisuuden kasvattamista toiminnan ilmastovaikutuksista ja ilmastonmuutoksen vaikutuksista toimintaan viestinnän ja seurantajärjestelmien keinoin sekä osana päätöksentekoprosesseja.

Työkyvyn johtaminen : Case Pirkanmaan Osuuskauppa

Tämän tutkimuksen tarkoituksena oli tutkia miten Pirkanmaan Osuuskaupan esimiehet ymmärtävät työhyvinvoinnin merkityksen esimiestyössään ja mitä asioita heidän tulisi vielä kehittää työhyvinvointi osaamisessaan. Työkyvyn johtamista verrattiin Elinkeinoelämän keskusliiton luomaan työkyvynjohtamisen malliin. Tutkimuksen pohjalta laadittiin ehdotuksia, jotta esimiesten osaamista, ymmärtämystä ja kykyä hyödyntää työhyvinvoinnin välineitä voitaisiin kehittää ja ylläpitää oikeilla toimenpiteillä. Yrityksissä työhyvinvointiin on alettu kiinnittää entistä enemmän huomiota kiireisen työtahdin, työn vaatimusten sekä työurien mahdollisten pidentymisen vuoksi, jolloin työnantajan lisäksi vaaditaan myös työntekijöiltä panostusta työhyvinvointiin. Tutkimus toteutettiin käyttämällä laadullista menetelmää. Aineiston keruu tehtiin puolistrukturoidun teemahaastattelun avulla. Haastatteluihin valikoitui 4 esimiestä. Haastattelujen avulla kartoitettiin esimiesten tietoja ja näkemyksiä työhyvinvoinnista ja heidän työhyvinvointiosaamisen tasosta. Tutkimuksen avulla selvisi, että esimiesten keskuudessa työhyvinvoinnin ylläpitämiseen ja kehittämiseen panostetaan vähemmän kuin mitä olisi mahdollista. Suurimmiksi esteiksi työhyvinvoinnin toteuttamiselle muodostuivat aika, resurssit ja asenteet. Pirkanmaan Osuuskaupan johtamistyön ja toimintatapojen välillä on eroja verrattuna Elinkeinoelämän keskusliiton työkykyjohtamisen malliin. Esimiestyö on mahdollisuuksia täynnä oleva kilpailuetu, mutta samalla myös huomattava haaste.

The early activities of front end of innovation in oem companies using a new fei platform as a framework for renewal

The main goal of this study is to create a seamless chain of actions and more detailed structure to the front end of innovation to be able to increase the front end performance and finally to influence the renewal of companies. The main goal is achieved through by the new concept of an integrated model of early activities of FEI leading to a discovery of new elements of opportunities and the identification of new business and growth areas. The procedure offers one possible solution to a dynamic strategy formation process in innovation development cycle. In this study the front end of innovation is positioned between a strategy reviews and a concept creation with needed procedures, tools, and frameworks. The starting point of the study is that the origins of innovation are not well enough understood. The study focuses attention on the early activities of FEI. These first activities are conceptualized in order to find out successful innovation initiatives and strategic renewal agendas. A seamless chain of activities resulting in faster and more precise identification of opportunities and growth areas available on markets and inside companies is needed. Three case studies were conducted in order to study company views on available theory doctrine and to identify the first practical experiences and procedures in the beginning of the front end of innovation. Successful innovation requires focus on renewal in both internal and external directions and they should be carefully balanced for best results. Instead of inside-out mode of actions the studied companies have a strong outside-in thinking mode and they mainly co-develop their innovation initiatives in close proximity with customers i.e. successful companies are an integral part of customers business and success. Companies have tailor-made innovation processes combined their way of working linked to their business goals, and priorities of actual needs of transformation. The result of this study is a new modular FEI platform which can be configured by companies against their actual business needs and drivers. This platform includes new elements of FEI documenting an architecture presenting how the system components work together. The system is a conceptual approach from theories of emergent strategy formation, opportunity identification and creation, interpretation-analysis-experimentation triad and the present FEI theories. The platform includes new features compared to actual models of FEI. It allows managers to better understand the importance of FEI in the whole innovation development stage and FEI as a phase and procedure to discover and implement emergent strategy. An adaptable company rethinks and redirects strategy proactively from time to time. Different parts of the business model are changed to remove identified obstacles for growth and renewal which gives them avenues to find right reforms for renewal.

Integrating Use of Customer Information Throughout Multiple Sales Channels to Create Customer Competence

Customer knowledge management (CKM) practices enable organizations to create customer competence with systematic use of customer information that is integrated throughout the organization. Nonetheless, organizations are not able to fully exploit the vast amount of data available. Previous research on use of customer information is limited especially in a multichannel environment. The aim of this study was to identify the main obstacles for utilizing customer information efficiently across multiple sales channels. The study was conducted as a single case study in order to gain deeper understanding of the research problem. The empirical findings indicate that lack of CKM practices and a common goal are major challenges obstructing effective utilization of customer information. Furthermore, decentralized organizational structure and insufficient analytical skills create obstacles for information sharing and capabilities to process information and create new knowledge. The implications of the study suggest that in order to create customer competence organizations should shift their focus from technology to the organizational factors affecting use of information and implement CKM practices throughout the organization.

“Why share in uncertain conditions?” Factors of individual level knowledge sharing in offshoring cases

The objective of this Master’s Thesis was to research factors influencing and enhancing individual level knowledge sharing in offshore projects which often involve uncertainty of the knowledge provider’s own future. The purpose was to understand why individuals are willing to share their knowledge under these kinds of circumstances. In addition the goal was to identify obstacles to interpersonal knowledge sharing in order to understand how to mitigate their influence. The research was conducted as a qualitative multiple case study in a global IT company, and the data was gathered using semi-structured personal theme interviews within two different offshore projects. In order to a gain a wider perspective on the matter, some management representatives were interviewed as well. Data was analysed with the inductive content analysis method. Results of the study indicate that individuals are willing to share their knowledge despite of uncertainty if they are motivated, if they are provided with opportunities to do so, and if they have skills, competence and experience to share their knowledge. A strong knowledge sharing culture in the organization or team also works as a strong incentive for individual level knowledge sharing. The findings suggest that even under uncertain conditions it is possible to encourage people to share their knowledge if uncertainty can be decreased to a bearable level, a robust and personal connection and relationship between the knowledge provider and acquirer can be created and suitable opportunities for knowledge sharing are provided. In addition, based on the results the support and commitment of management and HR in addition to favourable environmental circumstances play an essential role in building a bridge between the knowledge provider and acquirer in order to create a virtual environment and space for knowledge sharing: Ba.

Potential and Challenges of Analog Reconfigurable Computation in Modern and Future CMOS

In this work, the feasibility of the floating-gate technology in analog computing platforms in a scaled down general-purpose CMOS technology is considered. When the technology is scaled down the performance of analog circuits tends to get worse because the process parameters are optimized for digital transistors and the scaling involves the reduction of supply voltages. Generally, the challenge in analog circuit design is that all salient design metrics such as power, area, bandwidth and accuracy are interrelated. Furthermore, poor flexibility, i.e. lack of reconfigurability, the reuse of IP etc., can be considered the most severe weakness of analog hardware. On this account, digital calibration schemes are often required for improved performance or yield enhancement, whereas high flexibility/reconfigurability can not be easily achieved. Here, it is discussed whether it is possible to work around these obstacles by using floating-gate transistors (FGTs), and analyze problems associated with the practical implementation. FGT technology is attractive because it is electrically programmable and also features a charge-based built-in non-volatile memory. Apart from being ideal for canceling the circuit non-idealities due to process variations, the FGTs can also be used as computational or adaptive elements in analog circuits. The nominal gate oxide thickness in the deep sub-micron (DSM) processes is too thin to support robust charge retention and consequently the FGT becomes leaky. In principle, non-leaky FGTs can be implemented in a scaled down process without any special masks by using “double”-oxide transistors intended for providing devices that operate with higher supply voltages than general purpose devices. However, in practice the technology scaling poses several challenges which are addressed in this thesis. To provide a sufficiently wide-ranging survey, six prototype chips with varying complexity were implemented in four different DSM process nodes and investigated from this perspective. The focus is on non-leaky FGTs, but the presented autozeroing floating-gate amplifier (AFGA) demonstrates that leaky FGTs may also find a use. The simplest test structures contain only a few transistors, whereas the most complex experimental chip is an implementation of a spiking neural network (SNN) which comprises thousands of active and passive devices. More precisely, it is a fully connected (256 FGT synapses) two-layer spiking neural network (SNN), where the adaptive properties of FGT are taken advantage of. A compact realization of Spike Timing Dependent Plasticity (STDP) within the SNN is one of the key contributions of this thesis. Finally, the considerations in this thesis extend beyond CMOS to emerging nanodevices. To this end, one promising emerging nanoscale circuit element - memristor - is reviewed and its applicability for analog processing is considered. Furthermore, it is discussed how the FGT technology can be used to prototype computation paradigms compatible with these emerging two-terminal nanoscale devices in a mature and widely available CMOS technology.

Kevyen istutuskoneen suunnittelu puuntaimille

Työssä pyritään suunnittelemaan kevyempi versio jo olemassa olevasta puuntaimien istutuslaitteesta. Työ koostuu kahdesta osasta. Ensimmäisessä teoria osuudessa käydään läpi mekatronisen koneen suunnittelussa huomioitavia seikkoja ja järjestelmällistä tuotekehitysprosessia yleisesti. Toisessa osassa esitellään nykyisten istutuslaitteiden kehityshistoriaa ja nykyisin koneellisessa metsänistutuksessa käytössä olevia laitteita. Loppuratkaisujen aikaan saamisessa pyritään QFD-menetelmää käyttämällä saamaan aikaan kevyen istutuskoneen vaatimusprofiili ja profiilissa ilmi tulleiden vaatimusten ja toiveiden pohjalta kehitettiin ratkaisuja joilla perinteistä koneellista istutus toimintaa voidaan uudistaa. Materiaalinvalinnan avulla optimoitiin kevyttä istutuskonetta pyrkimällä löytämään ympäristöystävälliset materiaalit jotka ovat tuotteen elinkaarta kokonaisuutena ajatellen parhaat mahdolliset. Työssä saatiin aikaan malli jolla on mahdollista jatkokehittelyn jälkeen ja kunnolla tuotteistettuna edistää koneellisen metsänistutuksen yleistymistä. Työn aikana huomattiin, että suurimmat esteet metsän istutuksen koneellistumiselle ovat nykyisten koneiden korkeat hankinta- ja käyttökustannukset sekä koneiden käyttämisen vaatima ammattitaito. Kustannuksia alentamalla ja käyttökynnystä madaltamalla voi edistää koneellisen metsänistutuksen yleistymistä tehostamisen rinnalla.

Recombinant viruses as vaccines against viral diseases

Vaccine approaches to infectious diseases are widely applied and appreciated. Amongst them, vectors based on recombinant viruses have shown great promise and play an important role in the development of new vaccines. Many viruses have been investigated for their ability to express proteins from foreign pathogens and induce specific immunological responses against these antigens in vivo. Generally, gene-based vaccines can stimulate potent humoral and cellular immune responses and viral vectors might be an effective strategy for both the delivery of antigen-encoding genes and the facilitation and enhancement of antigen presentation. In order to be utilized as a vaccine carrier, the ideal viral vector should be safe and enable efficient presentation of required pathogen-specific antigens to the immune system. It should also exhibit low intrinsic immunogenicity to allow for its re-administration in order to boost relevant specific immune responses. Furthermore, the vector system must meet criteria that enable its production on a large-scale basis. Several viral vaccine vectors have thus emerged to date, all of them having relative advantages and limits depending on the proposed application, and thus far none of them have proven to be ideal vaccine carriers. In this review we describe the potential, as well as some of the foreseeable obstacles associated with viral vaccine vectors and their use in preventive medicine.

Pienet erikoiskaupat Big datan aikakaudella: Asiakastiedonjohtamisen edellyttämät strategiset orientaatiot.

This master’s thesis has examined how Entrepreneurial, Customer and Knowledge Management Orientations are needed in the use of Big data technology by small retail firms in their Customer Knowledge Management. A vision of the ability of small retailers to move to the Big data era is based on empirical evidence of owner-managers’ attitudes and the firms’ processes. Abductive content analysis was used as a research strategy and the qualitative data was collected through theme interviews of owner-managers of 11 small-size retail firms. The biggest obstacles to the use of Big data by small retail firms are: a lack of information about the new technology; a lack of Knowledge Management Orientation; and, a lack of proactive dimension in Entrepreneurial and Customer Orientations. A strong reactive customer-led orientation, and the ability of the owner-manager to system thinking will support Customer Knowledge Management development. The low stage of technology-use is preventing utilization of customer information. Co-operation between firms or with educational organizations may significantly enhance the use of Big data –technology by small retail firms.

Early responses of the STAT3 pathway to platinum drugs are associated with cisplatin resistance in epithelial ovarian cancer

Cisplatin resistance remains one of the major obstacles when treating epithelial ovarian cancer. Because oxaliplatin and nedaplatin are effective against cisplatin-resistant ovarian cancer in clinical trials and signal transducer and activator of transcription 3 (STAT3) is associated with cisplatin resistance, we investigated whether overcoming cisplatin resistance by oxaliplatin and nedaplatin was associated with the STAT3 pathway in ovarian cancer. Alamar blue, clonogenic, and wound healing assays, and Western blot analysis were used to compare the effects of platinum drugs in SKOV-3 cells. At an equitoxic dose, oxaliplatin and nedaplatin exhibited similar inhibitory effects on colony-forming ability and greater inhibition on cell motility than cisplatin in ovarian cancer. Early in the time course of drug administration, cisplatin increased the expression of pSTAT3 (Tyr705), STAT3α, VEGF, survivin, and Bcl-XL, while oxaliplatin and nedaplatin exhibited the opposite effects, and upregulated pSTAT3 (Ser727) and STAT3β. The STAT3 pathway responded early to platinum drugs associated with cisplatin resistance in epithelial ovarian cancer and provided a rationale for new therapeutic strategies to reverse cisplatin resistance.

Transcranial direct current stimulation and repetitive transcranial magnetic stimulation in consultation-liaison psychiatry

Patients with clinical diseases often present psychiatric conditions whose pharmacological treatment is hampered due to hazardous interactions with the clinical treatment and/or disease. This is particularly relevant for major depressive disorder, the most common psychiatric disorder in the general hospital. In this context, nonpharmacological interventions could be useful therapies; and, among those, noninvasive brain stimulation (NIBS) might be an interesting option. The main methods of NIBS are repetitive transcranial magnetic stimulation (rTMS), which was recently approved as a nonresearch treatment for some psychiatric conditions, and transcranial direct current stimulation (tDCS), a technique that is currently limited to research scenarios but has shown promising results. Therefore, our aim was to review the main medical conditions associated with high depression rates, the main obstacles for depression treatment, and whether these therapies could be a useful intervention for such conditions. We found that depression is an important and prevalent comorbidity in a variety of diseases such as epilepsy, stroke, Parkinson's disease, myocardial infarction, cancer, and in other conditions such as pregnancy and in patients without enteral access. We found that treatment of depression is often suboptimal within the above contexts and that rTMS and tDCS therapies have been insufficiently appraised. We discuss whether rTMS and tDCS could have a significant impact in treating depression that develops within a clinical context, considering its unique characteristics such as the absence of pharmacological interactions, the use of a nonenteral route, and as an augmentation therapy for antidepressants.

Comparison of conventional Papanicolaou cytology samples with liquid-based cervical cytology samples from women in Pernambuco, Brazil

In the present study, we compared the performance of a ThinPrep cytological method with the conventional Papanicolaou test for diagnosis of cytopathological changes, with regard to unsatisfactory results achieved at the Central Public Health Laboratory of the State of Pernambuco. A population-based, cross-sectional study was performed with women aged 18 to 65 years, who spontaneously sought gynecological services in Public Health Units in the State of Pernambuco, Northeast Brazil, between April and November 2011. All patients in the study were given a standardized questionnaire on sociodemographics, sexual characteristics, reproductive practices, and habits. A total of 525 patients were assessed by the two methods (11.05% were under the age of 25 years, 30.86% were single, 4.4% had had more than 5 sexual partners, 44% were not using contraception, 38.85% were users of alcohol, 24.38% were smokers, 3.24% had consumed drugs previously, 42.01% had gynecological complaints, and 12.19% had an early history of sexually transmitted diseases). The two methods showed poor correlation (k=0.19; 95%CI=0.11–0.26; P<0.001). The ThinPrep method reduced the rate of unsatisfactory results from 4.38% to 1.71% (χ2=5.28; P=0.02), and the number of cytopathological changes diagnosed increased from 2.47% to 3.04%. This study confirmed that adopting the ThinPrep method for diagnosis of cervical cytological samples was an improvement over the conventional method. Furthermore, this method may reduce possible losses from cytological resampling and reduce obstacles to patient follow-up, improving the quality of the public health system in the State of Pernambuco, Northeast Brazil.
