Identifying integrated options for agricultural climate change mitigation

Purpose: In order to achieve reductions in greenhouse gas emissions it is essential that all industry sectors have the appropriate knowledge and tools to contribute. This includes agriculture, which is considered to contribute about a third of emissions globally. This paper reports on one such tool: IMPACCT: Integrated Management oPtions for Agricultural Climate Change miTigation. Design/methodology/approach: IMPACCT focuses on greenhouse gas emissions, carbon sequestration and associated mitigation options. However, it also attempts to include information on economic and other environmental impacts in order to provide a more holistic perspective. The model identifies mitigation options, likely economic impacts and any synergies and trade-offs with other environmental objectives. The model has been applied on 22 case study farms in seven member states. Findings: The tool presents some useful concepts for developing carbon calculators in the future. It has highlighted that calculators need to evolve from simply calculating emissions to identifying cost effective and integrated emissions reduction options. Practical implications: IMPACCT has potential to become an effective means of provided targeted guidance, as part of a broader knowledge transfer programme based on an integrated suite of guidance, tools and advice delivered via different media. Originality/value: IMPACCT is a new model that demonstrates how to take a more integrated approach to mitigating greenhouse gas emissions on farms across Europe. It is a holistic carbon calculator that presents mitigation options in the context other environmental and economic objectives in the search for more sustainable methods of food production.Peer reviewedFinal Accepted Versio

Adaptive Transactional Memories: Performance and Energy Consumption Tradeoffs

Energy efficiency is becoming a pressing issue, especially in large data centers where it entails, at the same time, a non-negligible management cost, an enhancement of hardware fault probability, and a significant environmental footprint. In this paper, we study how Software Transactional Memories (STM) can provide benefits on both power saving and the overall applications’ execution performance. This is related to the fact that encapsulating shared-data accesses within transactions gives the freedom to the STM middleware to both ensure consistency and reduce the actual data contention, the latter having been shown to affect the overall power needed to complete the application’s execution. We have selected a set of self-adaptive extensions to existing STM middlewares (namely, TinySTM and R-STM) to prove how self-adapting computation can capture the actual degree of parallelism and/or logical contention on shared data in a better way, enhancing even more the intrinsic benefits provided by STM. Of course, this benefit comes at a cost, which is the actual execution time required by the proposed approaches to precisely tune the execution parameters for reducing power consumption and enhancing execution performance. Nevertheless, the results hereby provided show that adaptivity is a strictly necessary requirement to reduce energy consumption in STM systems: Without it, it is not possible to reach any acceptable level of energy efficiency at all

On top management support for software cost estimation

Inaccurate software cost estimates continue causing project overruns and hurting firms’ economy. This thesis addresses the problem by focusing on top management role in applying estimation methodologies successfully in organisations. The research questions are 1) How does top management support software cost estimation, and 2) What are the impacts of top management support for creating a good cost estimate for a software project? Three empirical studies, one quantitative and two qualitative, were conducted to address the research questions. The studies identified practices, through which top management is involved in cost estimation, and collected evidence on the impact of practices on estimation success. The quantitative study is based on views of 114 Finnish software professionals, and the quantitative studies are based on in-depth findings from three Finnish software producing companies and projects. The results show that top management support for estimation is mostly indirect. Management focuses on creating a successful environment for estimation instead of hands-on participation.The key factors of top management support include adequate resources, demonstrating the importance of estimation and seeking realism. This indirect role is enough for successful estimation.On the other hand, the results provide evidence that top management may negatively impact estimation. For example, unclear expectations may cause the project team to aim for the wrong outcome, expressed expectations may bias estimation and interpreting estimates as commitments may decrease estimators’ motivation and cause them to give high estimates. The practical implication is that top management should avoid direct participation in software estimation and focus on sustaining a supportive and unbiased environment. By doing this, many projects should be able to avoid failures hurting firms’ competitiveness. From the research perspective, the results provide evidence that people-related perspectives are an important factor in software estimation, implying that a shifting focus from methodologies toward managerial topics is justified.Epätarkat ohjelmistoprojektien kustannusarviot johtavat suunnitelmien ylittymiseen ja rasittavat yritysten taloutta. Tämä väitöskirja keskittyy ylimmän johdon rooliin arviointimenetelmien menestyksekkäässä soveltamisessa organisaatioissa. Väitöskirjan tutkimuskysymykset ovat 1) kuinka ylin johto tukee ohjelmistojen kustannusarviointia ja 2) mitä vaikutuksia johdon tuella hyvän kustannusarvion laatimiseksi on ohjelmistoprojektille? Väitöskirjan tulokset perustuvat yhteen määrälliseen ja kahteen laadulliseen tutkimukseen. Tutkimukset tunnistivat tapoja, joilla johto osallistui kustannusarviointiin sekä keräsi näyttöä osallistumiskäytänteiden vaikutuksista arvioinnin onnistumiseen. Määrällinen tutkimus pohjautuu 114 suomalaisen ohjelmistoammattilaisen näkemyksiin, kun taas laadulliset tutkimukset pohjautuvat löydöksiin kolmen suomalaisen ohjelmistoyrityksen toteuttamista kolmesta ohjelmistoprojektista. Tulokset osoittavat, että ylimmän johdon tuki arvioinnille on pääasiallisesti epäsuoraa. Johto keskittyy hyvien edellytysten luomiseen sen sijaan, että osallistuisi arviointiin henkilökohtaisesti. Tärkeimpiin tapoihin tukea arviointia kuuluvat mm. riittävien resurssien varmistaminen ja realististen arvioiden tavoittelu. Yllä kuvattu epäsuora osallistuminen on riittävää arvioinnin onnistumiseksi. Toisaalta johdon toimet voivat myös vaikuttaa arviointiin negatiivisesti. Esimerkiksi epäselvät tavoitteet saattavat johtaa väärien asioiden tavoitteluun, johdon esittämät odotukset voivat vääristää arvioinnin tuloksia ja arvioiden tulkitseminen lupauksiksi voi laskea arvioitsijoiden motivaatiota ja johtaa perusteettoman korkeiden arvioiden antamiseen. Esitettyjen tulosten perusteella johdon pitäisi välttää suoraa osallistumista arviointiin ja keskittyä arviointia tukevan ilmapiirin luomiseen. Näillä toimilla useat projektit voisivat todennäköisesti välttää yrityksille vahingolliset epäonnistumiset. Tutkimusnäkökulmasta tulokset osoittavat, että inhimilliset tekijät ovat merkittävässä roolissa kustannusarvioinnissa, ja lisäpanostukset johtamisnäkökulmien tutkimiseen ovat perusteltuja

Valuing Avoided Soil Erosion by Considering Private and Public Net Benefits

The population in New Zealand is expected to increase to over five million by the mid 2020’s from the current level of 4.3 million (Statistics New Zealand, 2009). An increasing demand for primary produce as a result may put pressure on marginal land to be farmed. Understanding the economic value of avoided erosion in New Zealand is therefore an important factor in policy making to optimise the soil related activities in the economy. Establishing a methodology for estimating the economic value of avoided soil erosion is the first step in assessing the problem. This study uses the future forest scenarios developed by Scion to identify potential afforestation areas and thereby compare the current erosion/sedimentation status under current land-use (non woody vegetation) with potential future afforestation. The study aims to quantify the incremental public and private net benefits from the change in scenario. The notion has come under different headings in the literature, such as on-site and off-site erosion effects or sediment and soil erosion effects, all of which recognize the importance of separation of effects to avoid double-counting. The separation into public and private benefits and costs in this case, while avoiding double-counting, will also help identify appropriate policy instruments to avoid soil erosion damage using the private and public net benefit framework (Pannell, 2008).Environmental Economics and Policy, Land Economics/Use,

An Overview of Economic Approaches to Information Security Management

The increasing concerns of clients, particularly in online commerce, plus the impact of legislations on information security have compelled companies to put more resources in information security. As a result, senior managers in many organizations are now expressing a much greater interest in information security. However, the largest body of research related to preventing breaches is technical, focusing on such issues as encryption and access control. In contrast, research related to the economic aspects of information security is small but rapidly growing. The goal of this technical note is twofold: i) to provide the reader with an structured overview of the economic approaches to information security and ii) to identify potential research directions
