Transportation and Iowa's Economic Future, 1993

This is a study of how transportation policy can be fashioned to improve Iowa's long-term economic prospects. The research focuses on the state level and covers pricing, resource allocation, investment, and other issues that directly affect the performance of public facilities that support transportation of goods and people to and from points in Iowa. Chapter 1 is an introduction. Chapter 2 begins with an assessment of how Iowa's economy is changing, both functionally and spatially. Commuting patterns and methods of goods movement are then discussed. The purpose of this analysis is to provide a context for the exploration of transportation policy issues in subsequent chapters. In Chapter 3 a framework is established for evaluating changes in transportation policies. A working definition of economic development is given and the role of government policies in making an area more attractive to economic activity is considered. Chapter 4 analyzes public policy options for Iowa's roads and highways. These policy options are intended to help the state compete for economic activity. Chapter 5 assesses alternative investment strategies for major navigational facilities on the upper Mississippi River. Chapter 6 examines major transportation policy issues in Iowa's agricultural sector. The current magnitude of agricultural shipments and the roles of several modes are presented. After focusing on issues related to railroad competitiveness, the analysis turns to how Iowa's rural roads should be financed. The need for joint investment and pricing decisions affecting waterways, railroads, and rural roads is stressed. Chapter 7 examines the current status of freight transportation in Iowa. An assessment is made of issues related to trucking and of intermodal transportation and its potential for cost-effective shipping to and from businesses in Iowa. Chapter 8 summarizes the key findings of this study, offering ten recommendations. These recommendations relate to transportation as a means of facilitating economic development.

Product Standardization of Shell and Tube Heat Exchangers

Diplomityön tavoitteena oli selvittää, kuinka kohdeyrityksessä nykyhetkellä pitkältiräätälöitynä tuotetut putkilämmönvaihtimet voitaisiin standardisoida, jotta pystyttäisiin kohdistamaan resursseja oikein ja parantamaan siten yrityksen taloudellista suorituskykyä. Tutkimuksen edetessä määräävimmäksi tekijäksi työn tuloksia ajatellen nousi taloudellinen standardisointiaste, jonka perusteeksi kohdeyrityksen putkilämmönvaihtimissa valittiin standardisoitu suunnitteluohjeisto. Suunnitteluohjeiston lisäksi tuotestandardiin liitettiin ehdotus toimintapojen automatisoimisesta parametrisen valintataulukon sekä sähköisen manuaalin avulla. Työssä tuotestandardisointia tarkastellaan rationalisointi-investointina ja sen kannattavuutta on tarkasteltu investointilaskelmien sekä herkkyys analyysin avulla. Alkuarvot investointilaskelmissa perustuvat työssä yhdelle putkilämmönvaihtimelletoteutettuun tuotestandardisointitapaan, jos tätä tapaa käytettäisiin jatkossa kaikkiin kyseisen yksikön putkilämmönvaihtimiin.

Kansainvälisen kilpailukyvyn perusteet pk-yrityksessä

Pk-yrityksen kansainvälistyminen on aina haasteellinen prosessi. Tähän haasteeseen on nyt tarttunut teräsohutlevyjen jatkojalostaja Metehe Oy, joka on patentoinut uuden julkisivujärjestelmän. Tutkimuksen tavoitteena on analysoida ja määrittää kansainvälisen kilpailukyvyn perusteet Metehe Oy:ssä uuden tuotteen osalta ja selvittää, mitä yritysominaisuuksia sen tulee priorisoida kansainvälistymisessään. Diplomityö pohjautuu strategisen johtamisen prosessiin.Ensin luodaan strategiset analyysit liiketoimintaympäristön ja sisäisten tekijöiden osalta. Sen jälkeen valitaan kilpailustrategia sekä kansainvälisen kaupan operaatiomuoto. Lopuksi suoritetaan strategian toimeenpano, jossa esitellään onnistumisen edellytyksiä ja kansainvälistymistoimenpiteitä. Metehe Oy:n uusi tuote on erittäin innovatiivinen, ja Metehe Oy:n kansainvälistymismahdollisuudet ovat hyvät sekä yrityksen sisäiset että ulkoiset tekijät huomioiden. Pk-yrityksenä Metehe Oy:n resurssit ovat kuitenkin rajalliset, mikä täytyy huomioida muun muassa kansainvälisen kaupan operaatiomuotoa valittaessa. Avaintekijäksi nousee tällöin resurssien allokointi eli kriittisimmät yritysominaisuudettulee tunnistaa.

Synergistic and antagonistic interaction between different branches of the immune system is related to melanin-based coloration in nestling tawny owls.

When exposed to parasites, hosts often mount energetically expensive immune responses, and this may alter resource allocation between competing life history traits including other components of the immune system. Here, we investigated whether a humoral immune challenge towards a vaccine reduces or enhances the cutaneous immune responses towards an injection of lipopolysaccharid (LPS, innate immunity) and phytohaemagglutinin (PHA, T-cell immunity) in nestling tawny owls in interaction with the degree of plumage melanin-based coloration. The humoral immune challenge enhanced the response to LPS similarly in differently coloured nestlings. In contrast, the same humoral immune challenge enhanced immune response to PHA in dark reddish melanic nestlings while reducing it in pale reddish melanic nestlings. Our results highlight that both antagonistic and synergistic interactions can take place among branches of immune system, and that the sign and magnitude of these interactions can vary with immune responses involved and the degree of melanin-based coloration.

New Product Development (NPD) Success Factors: A Review of the Literature

This paper reviews the literature on managerially actionable new product development success factors and summarises the field in a classic managerial framework. Because of the varying quality, breadth and scope of the field, the review only contains post-1980 studies of tangible product development that are of a rigorous scientific standard. Success is interpreted as a commercial success. The field has gained insight into a broad set of factors that vary in scope, abstraction and context. Main areas that contribute to NPD success are top management support exhibited through resource allocation and communicating the strategic importance of NPD in the organisation. The right projects need to be selected for investment at the beginning of the process and should be aligned to the organisation's internal competencies and the external environment. The NPD process should use cross-functional teams and a competent project champions. Marketing research competency is crucial, as an understanding of the market, customers and competitors is repeatedly highlighted. Product launch competency was also consistently shown to be important. In terms of controlling the NPD process, strict project gates are required to maintain control.

JOHDON LASKENTATOIMI KÄRKIYRITYSVERKOSTOISSA Soveltamismahdollisuudet ja yritysten tarpeet

Tutkimus tarkastelee johdon laskentatoimea yritysverkostoissa. Tutkimuksen tavoitteena on lisätä ymmärrystä koskien sitä, millaisia tarpeita verkostoituneilla yrityksillä on johdon laskentatoimen suhteen ja millaiset ovat verkostotasoisten laskentajärjestelmien soveltamismahdollisuudet. Johdon laskentatoimea ja yritysverkostoja on tutkittu erillisinä alueina jo varsin pitkään, mutta verkostoituneen toimintamuodon yleistymisestä huolimatta johdon laskentatoimen tutkimus nimenomaan verkostoympäristössä onvasta alkuvaiheessa. Tämä tutkimus on toteutettu suomalaisissa verkostoituneissa metalliteollisuusyrityksissä. Tutkitut verkostot muodostuvatverkoston ydinyrityksestä ¿ kärkiyrityksestä - ja sen ympärille ryhmittyneistä pienistä toimittajayrityksistä. Tutkimus on toteutettu käyttäen teemahaastatteluja, joita suoritettiin neljässä eri yritysverkostossa. Tutkimusote on luonteeltaan laadullinen ja pääosin kuvaileva. Verkostojen laskentatoimen tutkimuksessa pienten toimittajayritysten näkemykset ja asenteet laskennan kehittämistä kohtaan ovat jääneet taka-alalle. Tämän tutkimuksen keskeisenä näkökulmana on juuri verkostoituneiden pk-yritystentarpeet, asenteet ja mahdollisuudet osallistua laskentatoimen kehitystyöhön. Tutkimuksessa tarkastellaan johdon laskentatoimea yleisellä tasolla, eikä rajauduta yksittäisiin menetelmiin. Tutkimus toi esille joitakin informaatiotarpeita verkostotasolla. Useita jalostusvaiheita eri yrityksissä käsittävässä tuotannossa vaikeutena on tietää tarkalleen missä tilaus etenee ja milloin tilaus saapuu yritykseen jalostettavaksi. Toimittajayritykset kaipaavat myös tarkempaa ja pidemmän ajanjakson kattavaa tietoa verkoston kärkiyrityksen tilauskannasta. Informaatiopuutteet aiheuttavat turhaa työtä ja vaikeuttavat resurssien ohjausta. Tutkituissa verkostoissa suunnittelua avustavalle budjetoinnille olisi tarpeita, mutta yhteistä budjetointia ei ole käytännössä toteutettu. Verkostojen laskentatoimessa kustannusten avoin esittäminen kumppaneille tai yleisemmin avoimuus koskien muitakin toiminnan mittareita on keskeisin tekijä, johon verkoston laskentatoimen toteuttaminen tiivistyy. Tutkituista verkostoista kahdessa avoimuus toteutui koskien kustannuksia, kahdessa muussa verkostossa kärkiyritykset eivät nähneet toimittajien kustannustietoja verkoston kilpailukyvyn kannalta merkittäväksi. Kustannusten avoimen esittämisen taustatekijöinä korostuivat kärkiyrityksen tuki, monimutkaisten konstruktioiden aiheuttamat hinnoitteluongelmat ja kannattavan asiakassuhteen varmistaminen. Verkostolaskennan kehittämisessä kärkiyrityksen rooli korostuu. Jos toimittajayritykset eivät tunnista verkostolaskennan tarjoamia mahdollisuuksia toiminnan yhteisessä kehittämisessä ja ohjaamisessa, on kärkiyrityksen pystyttävä perustelemaan toimittajille uskottavasti mitä hyötyä laskentajärjestelmistä on koko verkostolle ja erityisesti toimittajayrityksille. Tutkittujen yritysten on pystyttävä rutinoimaan nyt yleisellä tasolla toimiva keskustelu järjestelmälliseksi suunnittelu- ja ohjaustyöksi. Hyvät kokemuksetyksinkertaisistakin laskenta- ja seurantajärjestelmistä parantavat mahdollisuuksia soveltaa myös kattavampia ja luottamuksellisempaa tietoa sisältäviä laskentajärjestelmiä.

Logging residues from regeneration fellings for biofuel production - a GIS-based availability and supply cost analysis

Finland has large forest fuel resources. However, the use of forest fuels for energy production has been low, except for small-scale use in heating. According to national action plans and programs related to wood energy promotion, the utilization of such resources will be multiplied over the next few years. The most significant part of this growth will be based on the utilization of forest fuels, produced from logging residues of regeneration fellings, in industrial and municipal power and heating plants. Availability of logging residues was analyzed by means of resource and demand approaches in order to identify the most suitable regions with focus on increasing the forest fuel usage. The analysis included availability and supply cost comparisons between power plant sites and resource allocation in a least cost manner, and between a predefined power plant structure under demand and supply constraints. Spatial analysis of worksite factors and regional geographies were carried out using the GIS-model environment via geoprocessing and cartographic modeling tools. According to the results of analyses, the cost competitiveness of forest fuel supply should be improved in order to achieve the designed objectives in the near future. Availability and supply costs of forest fuels varied spatially and were very sensitive to worksite factors and transport distances. According to the site-specific analysis the supply potential between differentlocations can be multifold. However, due to technical and economical reasons ofthe fuel supply and dense power plant infrastructure, the supply potential is limited at plant level. Therefore, the potential and supply cost calculations aredepending on site-specific matters, where regional characteristics of resourcesand infrastructure should be taken into consideration, for example by using a GIS-modeling approach constructed in this study.

Communicating geomorphology: global challenges for the twenty-first century

The British Society for Geomorphology (BSG), established as the British Geomorphological Research Group (BGRG) in 1960, is considering how best to represent geomorphology and geomorphologists in the light of recent changes in the nature of communication. These changes provide the BSG and other academic societies with challenges and opportunities. Seven drivers of communication change are outlined: the changing position of geomorphology in higher education, the nature of academic interaction, the means of communication available, a transformation in the nature of geomorphological research, changes in funding support, the government role in resource allocation, and developments in quantifying international research impact. Challenges arising from changing communications are identified as occurring beyond the `academy', in the nature of publication within the `academy', and associated with meetings of the `academy'. Although national societies now have to contemplate significantly different purposes to provide for their members than in the twentieth century, there are opportunities available that cannot be fulfilled by international organizations alone.

Optimizing the Anti-VEGF Treatment Strategy for Neovascular Age-Related Macular Degeneration: From Clinical Trials to Real-Life Requirements.

NlmCategory="UNASSIGNED">This Perspective discusses the pertinence of variable dosing regimens with anti-vascular endothelial growth factor (VEGF) for neovascular age-related macular degeneration (nAMD) with regard to real-life requirements. After the initial pivotal trials of anti-VEGF therapy, the variable dosing regimens pro re nata (PRN), Treat-and-Extend, and Observe-and-Plan, a recently introduced regimen, aimed to optimize the anti-VEGF treatment strategy for nAMD. The PRN regimen showed good visual results but requires monthly monitoring visits and can therefore be difficult to implement. Moreover, application of the PRN regimen revealed inferior results in real-life circumstances due to problems with resource allocation. The Treat-and-Extend regimen uses an interval based approach and has become widely accepted for its ease of preplanning and the reduced number of office visits required. The parallel development of the Observe-and-Plan regimen demonstrated that the future need for retreatment (interval) could be reliably predicted. Studies investigating the observe-and-plan regimen also showed that this could be used in individualized fixed treatment plans, allowing for dramatically reduced clinical burden and good outcomes, thus meeting the real life requirements. This progressive development of variable dosing regimens is a response to the real-life circumstances of limited human, technical, and financial resources. This includes an individualized treatment approach, optimization of the number of retreatments, a minimal number of monitoring visits, and ease of planning ahead. The Observe-and-Plan regimen achieves this goal with good functional results. Translational Relevance: This perspective reviews the process from the pivotal clinical trials to the development of treatment regimens which are adjusted to real life requirements. The article discusses this translational process which- although not the classical interpretation of translation from fundamental to clinical research, but a subsequent process after the pivotal clinical trials - represents an important translational step from the clinical proof of efficacy to optimization in terms of patients' and clinics' needs. The related scientific procedure includes the exploration of the concept, evaluation of security, and finally proof of efficacy.

A geometric chracterization of the nucleolus of the assignment game

Maschler et al. (1979) caracteritzen geomètricament la intersecció del kernel i del core en els jocs cooperatius, demostrant que les distribucions que pertanyen a ambdós conjunts es troben en el punt mig d’un cert rang de negociació entre parelles de jugadors. En el cas dels jocs d’assignació, aquesta caracterització vol dir que el kernel només conté aquells elements del core on el màxim que un jugador pot transferir a una parella òptima és igual al màxim que aquesta parella li pot transferir, sense sortir-se’n del core. En aquest treball demostrem que el nucleolus d’un joc d’assignació queda caracteritzat si requerim que aquesta propietat de bisecció es compleixi no només per parelles, sinó també per coalicions entre sectors aparellades òptimament.

Do standard burn mortality formulae work on a population of severely burned children and adults?

Accurate prediction of mortality following burns is useful as an audit tool, and for providing treatment plan and resource allocation criteria. Common burn formulae (Ryan Score, Abbreviated Burn Severity Index (ABSI), classic and revised Baux) have not been compared with the standard Acute Physiology and Chronic Health Evaluation II (APACHEII) or re-validated in a severely (≥20% total burn surface area) burned population. Furthermore, the revised Baux (R-Baux) has been externally validated thoroughly only once and the pediatric Baux (P-Baux) has yet to be. Using 522 severely burned patients, we show that burn formulae (ABSI, Baux, revised Baux) outperform APACHEII among adults (AUROC increase p<0.001 adults; p>0.5 children). The Ryan Score performs well especially among the most at-risk populations (estimated mortality [90% CI] original versus current study: 33% [26-41%] versus 30.18% [24.25-36.86%] for Ryan Score 2; 87% [78-93%] versus 66.48% [51.31-78.87%] for Ryan Score 3). The R-Baux shows accurate discrimination (AUROC 0.908 [0.869-0.947]) and is well-calibrated. However, the ABSI and P-Baux, although showing high measures of discrimination (AUROC 0.826 [0.737-0.916] and 0.848 [0.758-0.938]) in children), exceedingly overestimates mortality, indicating poor calibration. We highlight challenges in designing and employing scores that are applicable to a wide range of populations.

Strategy Formulation and Implementation Case of High Tech Instruments

The strategy process is a method for strategy formulation and implementation. The strategy process is commonly used especially within bigger companies. It is important to link the strategy formulation and implementation. The objective of this thesis has been to find out improvement areas for the case company’s strategy process. The theoretical framework based on literature emphasizes on strategy process as a method for strategy formulation and implementation. The theoretical framework, several mainly ad hoc interviews and author’s observation were used as tools to analyze the case company’s strategy process. The hierarchy in between the various corporate levels provides the foundation to formulate and implement the strategies. These strategies include the corporate and strategic business area level strategies. The recommendations to improve the case company’s strategy process were formulated at corporate and strategic business area levels. These recommendations were formulated based on research and experience gained throughout the work. The role of strategic projects to implement the strategies more efficiently and organizational control over distribution were found as potential improvement areas. The resource allocation prioritizing towards the most important strategic projects was also an important improvement area.

Stable eusociality via maternal manipulation when resistance is costless.

In many eusocial species, queens use pheromones to influence offspring to express worker phenotypes. Although evidence suggests that queen pheromones are honest signals of the queen's reproductive health, here I show that queen's honest signalling can result from ancestral maternal manipulation. I develop a mathematical model to study the coevolution of maternal manipulation, offspring resistance to manipulation and maternal resource allocation. I assume that (i) maternal manipulation causes offspring to be workers against offspring's interests; (ii) offspring can resist at no direct cost, as is thought to be the case with pheromonal manipulation; and (iii) the mother chooses how much resource to allocate to fertility and maternal care. In the coevolution of these traits, I find that maternal care decreases, thereby increasing the benefit that offspring obtain from help, which in the long run eliminates selection for resistance. Consequently, ancestral maternal manipulation yields stable eusociality despite costless resistance. Additionally, ancestral manipulation in the long run becomes honest signalling that induces offspring to help. These results indicate that both eusociality and its commonly associated queen honest signalling can be likely to originate from ancestral manipulation.

European cancer mortality predictions for the year 2016 with focus on leukemias.

BACKGROUND: Current cancer mortality statistics are important for public health decision making and resource allocation. Age standardized rates and numbers of deaths are predicted for 2016 in the European Union. PATIENTS AND METHODS: Population and death certification data for stomach, colorectum, pancreas, lung, breast, uterus, prostate, leukemia and total cancers were obtained from the World Health Organisation database and Eurostat. Figures were derived for the EU, France, Germany, Italy, Poland, Spain and the UK. Projected numbers of deaths by age group were obtained for 2016 by linear regression on estimated numbers of deaths over the most recent time period identified by a joinpoint regression model. RESULTS: Projected total cancer mortality trends for 2016 in the EU are favourable in both sexes with rates of 133.5/100,000 men and 85.2/100,000 women (8% and 3% falls since 2011, due to population ageing) corresponding to 753,600 and 605,900 deaths in men and women for a total number of 1,359,500 projected cancer deaths (+3% compared to 2011). In men lung, colorectal and prostate cancer fell 11%, 5% and 8% since 2011. Breast and colorectal cancer trends in women are favourable (8% and 7% falls, respectively), but lung and Pancreatic cancer rates rose 5% and 4% since 2011 reaching rates of 14.4 and 5.6/100,000 women. Leukemia shows favourable projected mortality for both sexes and all age groups with stronger falls in the younger age groups, rates are 4.0/100,000 men and 2.5/100,000 women, with respectively falls of 14% and 12%. CONCLUSION: The 2016 predictions for EU cancer mortality confirm the favourable trends in rates particularly for men. Lung cancer is likely to remain the leading site for female cancer rates. Continuing falls in mortality, larger in children and young adults, are predicted in leukemia, essentially due to advancements in management and therapy, and their subsequent adoption across Europe.
