Palaeoclimatic implications of the growth history and stable isotope (delta O-18 and delta C-13) geochemistry of a Middle to Late Pleistocene stalagmite from central-western Italy

The age structure and, stable isotope composition of a stalagmite (CC I) from an upland cave in central-western Italy were studied to investigate regional response to global climatic changes. Four growth phases are constrained by 28 thermal ionization and multi-collector inductively coupled plasma mass spectrometry Th-U ages and reveal intermittent deposition through the period between Marine isotope Stage (MIS) 11 and 3 (similar to380 and similar to43 kyr). Most of the growth took place between similar to380 and similar to280 kyr, a period punctuated briefly by a hiatus in deposition through the glacial maximum of MIS 10. Growth was terminated abruptly at 280 kyr just prior to the MIS 8 glacial maximum. With a present-day chamber temperature of 7.5 degreesC, the timing of hiatuses close to these glacial maxima point to freezing conditions at the time. No deposition was recorded through the entirety of MIS 7 and most of MIS 6, whilst two minor growth phases occurred at similar to141-125 and similar to43 kyr. Growth at 141 kyr indicates temperatures >0 degreesC at a time when MIS 6 ice volumes were close to their maximum. High stable carbon isotope (delta(13)C) values (similar to2.8parts per thousand to +3.1parts per thousand) throughout the stalagmite's growth reflect a persistently low input of biogenic CO2, indicating that the steep, barren and alpine-like recharge area of today ha's been in existence for at least the last similar to380 kyr. During MIS 9, the lowest delta(13)C values occur well after maximum interglacial conditions, suggesting a lag in the development of post-glacial soils in this high-altitude karst. The stable oxygen isotope (delta(18)O) trends match the main structural features of the major climate proxy records (SPECMAP, Vostok and Devils Hole), suggesting that the delta(18)O of CC1 has responded to global-scale climate changes, whilst remarkable similarity exists between CC1 delta(18)O and regional sea-surface temperature reconstructions from North Atlantic core ODP980 and southwest Pacific marine core MD97-2120 through the most detailed part of the CC1 record, MIS 9-8. The results suggest that CC1 and other stalagmites from the cave have the potential to capture a long record of regional temperature trends, particularly in regards to the relative severity of Pleistocene glacial stages.

Linking riparian vegetation spatial structure in Australian tropical savannas to ecosystem health indicators: semi-variogram analysis of high spatial resolution satellite imagery

Government agencies responsible for riparian environments are assessing the combined utility of field survey and remote sensing for mapping and monitoring indicators of riparian zone health. The objective of this work was to determine if the structural attributes of savanna riparian zones in northern Australia can be detected from commercially available remotely sensed image data. Two QuickBird images and coincident field data covering sections of the Daly River and the South Alligator River - Barramundie Creek in the Northern Territory were used. Semi-variograms were calculated to determine the characteristic spatial scales of riparian zone features, both vegetative and landform. Interpretation of semi-variograms showed that structural dimensions of riparian environments could be detected and estimated from the QuickBird image data. The results also show that selecting the correct spatial resolution and spectral bands is essential to maximize the accuracy of mapping spatial characteristics of savanna riparian features. The distribution of foliage projective cover of riparian vegetation affected spectral reflectance variations in individual spectral bands differently. Pan-sharpened image data enabled small-scale information extraction (< 6 m) on riparian zone structural parameters. The semi-variogram analysis results provide the basis for an inversion approach using high spatial resolution satellite image data to map indicators of savanna riparian zone health.

Linking the witness simulation software to an expert system to represent a decision-making process

Expert systems, and artificial intelligence more generally, can provide a useful means for representing decision-making processes. By linking expert systems software to simulation software an effective means of including these decision-making processes in a simulation model can be achieved. This paper demonstrates how a commercial-off-the-shelf simulation package (Witness) can be linked to an expert systems package (XpertRule) through a Visual Basic interface. The methodology adopted could be used for models, and possibly software, other than those presented here.

Linking comprehensive performance assessment to the balanced scorecard:evidence from Hertfordshire County Council

Over the course of the last twenty years there has been a growing academic interest in performance management, particularly in respect of the evolution of new techniques and their resulting impact. One important theoretical development has been the emergence of multidimensional performance measurement models that are potentially applicable within the public sector. Empirically, academic researchers are increasingly supporting the use of such models as a way of improving public sector management and the effectiveness of service provision (Mayston, 1985; Pollitt, 1986; Bates and Brignall, 1993; and Massey, 1999). This paper seeks to add to the literature by using both theoretical and empirical evidence to argue that CPA, the external inspection tool used by the Audit Commission to evaluate local authority performance management, is a version of the Balanced Scorecard which, when adapted for internal use, may have beneficial effects. After demonstrating the parallels between the CPA framework and Kaplan and Norton's public sector Balanced Scorecard (BSC), we use a case study of the BSC based performance management system in Hertfordshire County Council to demonstrate the empirical linkages between a local scorecard and CPA. We conclude that CPA is based upon the BSC and has the potential to serve as a springboard for the evolution of local authority performance management systems.

Linking the ecosystem service approach to social preferences and needs in integrated coastal land use management - a planning approach

Coastal zones with their natural and societal subsystems are exposed to rapid changes and pressures on resources. Scarcity of space and impacts of climate change are prominent drivers of land use and adaptation management today. Necessary modifications to present land use management strategies and schemes influence both the structures of coastal communities and the ecosystems involved. Approaches to identify the impacts and account for (i) the linkages between social references and needs and (ii) ecosystem services in coastal zones have been largely absent. The presented method focuses on improving the inclusion of ecosystem services in planning processes and clarifies the linkages with social impacts. In this study, fourteen stakeholders in decisionmaking on land use planning in the region of Krummhörn (northwestern Germany, southern North Sea coastal region) conducted a regional participative and informal process for local planning capable to adapt to climate driven changes. It is argued that scientific and practical implications of this integrated assessment focus on multifunctional options and contribute to more sustainable practices in future land use planning. The method operationalizes the ecosystem service approach and social impact analysis and demonstrates that social demands and provision of ecosystem services are inherently connected.

A Value Networks Approach to Implementing Integrated Cross-National Business Operations

The removal of trade impediments is expected to cause companies to integrate more of their operations among countries; however, experience shows that behavioral factors often impede the requisite cooperation and commitment among managers from different countries. This paper discusses these behavioral problems from a national perspective and examines an approach to integration, value networks, which is not bounded by nation-states and their differences or similarities.

Microbiological indicators for the assessment of performance in the hazard analysis and critical control points (HACCP) system in meat lasagna production

The HACCP system is being increasingly used to ensure food safety. This study investigated the validation of the control measures technique in order to establish performance indicators of this HACCP system in the manufacturing process of Lasagna Bolognese (meat lasagna). Samples were collected along the manufacturing process as a whole, before and after the CCPs. The following microorganism s indicator (MIs) was assessed: total mesophile and faecal coliform counts. The same MIs were analyzed in the final product, as well as, the microbiological standards required by the current legislation. A significant reduction in the total mesophile count was observed after cooking (p < 0.001). After storage, there was a numerical, however non-significant change in the MI count. Faecal coliform counts were also significantly reduced (p < 0.001) after cooking. We were able to demonstrate that the HACCP system allowed us to meet the standards set by both, the company and the Brazilian regulations, proved by the reduction in the established indicators

COST Action TU1406: eBook of the 1st Workshop Meeting

COST Action TU1406 aims to address the European economic and societal needs by standardizing the condition assessment and maintenance level of roadway bridges. Currently, bridge quality control plans vary from country to country and, in some cases, within the same country. This therefore urges the establishment of a European guideline to surpass the lack of a standard methodology to assess bridge condition and to define quality control plans for roadway bridges. Such a guideline will comprise specific recommendations for assessing performance indicators as well as for the definition of performance goals, bringing together different stakeholders (e.g. universities, institutes, operators, consultants and owners) from various scientific disciplines (e.g. on-site testing, visual inspection, structural engineering, sustainability, etc.) in order to establish a common transnational language. COST Action TU1406 Workshops aim to facilitate the exchange of ideas and experiences between active researchers and practitioners as well as to stimulate discussions on new and emerging issues in line with the conference topics. This first Workshop essentially focuses on WG1 issues, namely, intends to address performance indicators, how these are assessed (e.g. visual inspection, nondestructive tests and monitoring systems), with what frequency and what values are generally obtained. The main outcomes, given in this eBook, were really important, not only for WG1 developments, but also for all the other WGs and for the Action itself.

Suorityskyvyn mittaaminen johtamisen apuvälineenä prosessiorganisaatiossa.

Prosessiorganisaatiossa johtamisen ja prosessien tavoitteena on tyydyttää asiakkaan (sisäinen tai ulkoinen) tarpeet. Mittaamisen sitominen prosessin suorityskyvyn mittaamiseen antaa johdolle kuvan yrityksen toiminnasta. Suorityskykymittariston ja yksittäisten mittareiden avulla yritysjohto pystyy arvioimaan toiminnan tasoa, asettamaan tavoitteita sekä seuraamaan asettamiensa tavoitteiden toteutumista. Työn ensimmäisenä tavoitteena oli kartoittaa edellytyksiä sekä tukea Balanced Scorecardin mukaisen suorityskykymittariston tulevaisuuden implementointia. Mittaristo on tarkoitettu toimitusketjun prosessien tehokkuuden mittaamiseen. Työn toisena tavoitteena oli prosessipohjaisen ajattelutavan tukeminen suorituskykymittariston avulla. Implementoinnin edellytyksiä testattiin valitsemalla kaksi ensimmäisen tason avainmittaria pilottimittareiksi. Varaston suorityskykyä mittaavien pilottimittareiden avulla selvitettiin SC tuoteryhmän osalta toimitusketjun suorituskyky avainasiakkaiden ja tärkeiden markkina-alueiden osalta. Erona käytössä oleviin mittareihin on se, että uudet avainmittarit kattavat koko yrityksen toimitusketjun, kun tällä hetkellä käytössä olevat mittarit mittaavat toimitusketjun yksittäisiä osia. Uusien avaimittareiden lähtöarvot selvitettiin tietokantakyselyjen avulla. Tietokyselyt suoritettiin useissa yksittäisissä tietojärjejestelmissä, jonka jälkeen niiden tulokset koottiin yhteen tiedostoon ja analysoitiin PC sovellusten avulla. Mittauskohteet oli valittu yhdessä linjaorganisaation kanssa. Näin taattiin yhtiön johdon sitoutuminen mittariston kehittämiseen ja käyttöönottoon. Organisaatiossa yksittäisten prosessien (esim. mittaamisprosessi) vastuualueiden selventämiseen käytettiin koeluonteisesti vastuumatriisitekniikkaa.

Finnair konsernin GRI raportoinnin kehittäminen

Tämän tutkintotyön tavoitteena on ollut Finnair konsernin GRI raportoinnin kehittäminen. Tutkintotyön osuus koko GRI projektissa on ollut toimintaindikaattoreiden määrittäminen. Tavoitteena oli määrittää toimintaindikaattorit Finnair konsernin ensimmäiseen GRI raporttiin niin, että raportti täyttää vähintään ohjeistuksessa määritellyn C-sovellustason vaatimukset. Asetettu C sovellustason tavoite saavutettiin G3 profiili kohdassa, ja ylitettiin selvästi G3 toimintaindikaattoreiden osalta, jossa varsinkin taloudelliset, sekä ymparistöpuolen toimintaindikaattorit saatiin tulevia raportteja ja korkeampaa sovellustasoa ajatellen hyvälle mallille. Tutkintotyön taustoittavassa osassa selvitettiin yhteiskuntavastuuraportin merkitystä organisaatiolle ja sen sidosryhmille, sekä läpikäytiin markkinoilla olevia eri yhteiskuntavastuuraportointivaihtoehtoja ja niiden merkittävimpiä eroavaisuuksia. Empiirisessä osassa puolestaan keskityttiin selvittämään, mitkä indikaattorit ovat olennaisia ja mahdollisia selvittää Finnair konsernin ensimmäisessä GRI raportissa.
