Do So

AbstractParty elites in coalition governments are acutely aware that the deals they strike will be critically evaluated by their supporters, and that they risk losing support if they are perceived as ineffective negotiators. This has a powerful influence on the bargains parties strike. Because most supporters are unaware of the complex aspects of bargains and instead rely on simple heuristics to evaluate their most visible features, parties have incentives to meet supporter expectations primarily on easily observable outcomes. To do so, they make trade-offs on less observable outcomes. This implies that the more visible features of a bargain typically do not accurately reflect the relative success of parties in coalition negotiations. We evaluate our argument using original data on the office rewards and policy risks of portfolio allocation in 16 parliamentary democracies. Our findings support our argument, and they have important implications for the nature of representation under multiparty government.

Selection Of

The article presents the analysis fossil fuel power generation market, focusing on management of advanced fossil fuel (AFF) power generation challenges of related technologies especially when tackling climate change impacts, complying with stricter environmental requirements. A wide and dynamic spectrum in scope and scale of factors revealed confirms the necessity for solutions enabling organizations to transform and manage rationally their fossil fuel-based business models towards greater competitiveness in the context of emerging renewable energy reliance. Nevertheless, in this respect the measures in question may require trade-offs, therefore when considering their combination, a diligent multicriteria analysis will inevitably be involved. With pivotal focus on the economic utility and the balanced and sustained strategic development of business, as the result of the research author proposes to apply VIKOR method when deciding on AFF power generation options. Application flexibility of the proposed method allow to evaluate, compare possible alternatives in a comprehensive and complex manner and to mingle MCDA tools if needed.

Sustainable Energy Systems

The assessment of future options and pathways for sustainable energy systems requires considering multiple techno-economic, ecological and social issues. Multicriteria analysis methods, which are useful tools that aid decision processes involving various and even conflicting qualitative and quantitative criteria, could support such comprehensive analyses. With regard to energy policies, the key actors and stakeholders’ acceptance of emerging and innovative technologies for generating, converting and storing electricity, heat and fuels is crucial for their future implementation. The multiactor multicriteria (MAMCA) methodology was developed to involve stakeholders with vastly different views and objectives when addressing complex societal problems. We extend the MAMCA methodology to include the outranking approach PROMETHEE, which allows us to explicitly consider the stakeholders’ objectives in the evaluation process. The MAMCA method with PROMETHEE is applied to a case study of four different transition pathways of providing electricity to a bioenergy village in Germany. The explicit mapping at hand of an illustrative case study could help researchers and decision makers greatly in the assessment of pathways for sustainable energy systems; it is also applicable in other contexts requiring extensive stakeholder involvement and where qualitative and quantitative criteria are to be considered simultaneously. The detailed sensitivity analysis provided by the extension of the MAMCA method with PROMETHEE not only reveals the stakeholders’ crucial trade-offs when allowing each stakeholder group to develop its own set of criteria and weights but also indicates compromise options.

Human Need ◽

Basic Human Needs

Development planning is a multicriteria problem. Apart from economic goals (like economic growth, income distribution, employment, price stability, balance of payments, etc.) a set of basic human needs (like food, health , housing, clothing, education, etc.) has to be fulfilled within a limited time horizon. Of course, not all targets of economic policy can reach desirable levels within a plan period given scarce resources and trade-offs between goals and basic needs. Priorities have to be formulated and goals and needs have to be weighted against another. Multicriteria analysis can contribute to this weighing process by circumscribing feasible areas and by quantifying above mentioned trade-offs. The purpose of this paper is to present an illustration of multicriteria analysis in which at least two goals of economic policy (growth and employment) and one basic human need (education) are incorporated. The model is applied to Pakistan due to data access.

Jasmonates (JAs) are essential signalling molecules that co-ordinate the plant response to biotic and abiotic challenges, as well as co-ordinating several developmental processes. Huge progress has been made over the last decade in understanding the components and mechanisms that govern JA perception and signalling. The bioactive form of the hormone, (+)-7-iso-jasmonyl-l-isoleucine (JA-Ile), is perceived by the COI1–JAZ co-receptor complex. JASMONATE ZIM DOMAIN (JAZ) proteins also act as direct repressors of transcriptional activators such as MYC2. In the emerging picture of JA-Ile perception and signalling, COI1 operates as an E3 ubiquitin ligase that upon binding of JA-Ile targets JAZ repressors for degradation by the 26S proteasome, thereby derepressing transcription factors such as MYC2, which in turn activate JA-Ile-dependent transcriptional reprogramming. It is noteworthy that MYCs and different spliced variants of the JAZ proteins are involved in a negative regulatory feedback loop, which suggests a model that rapidly turns the transcriptional JA-Ile responses on and off and thereby avoids a detrimental overactivation of the pathway. This chapter highlights the most recent advances in our understanding of JA-Ile signalling, focusing on the latest repertoire of new targets of JAZ proteins to control different sets of JA-Ile-mediated responses, novel mechanisms of negative regulation of JA-Ile signalling, and hormonal cross-talk at the molecular level that ultimately determines plant adaptability and survival.

Speed And Accuracy

In most work contexts, several performance goals coexist, and conflicts between them and trade-offs can occur. Our paper is the first to contrast a dual goal for speed and accuracy with a single goal for speed on the same task. The Sternberg paradigm (Experiment 1, n = 57) and the d2 test (Experiment 2, n = 19) were used as performance tasks. Speed measures and errors revealed in both experiments that dual as well as single goals increase performance by enhancing memory scanning. However, the single speed goal triggered a speed-accuracy trade-off, favoring speed over accuracy, whereas this was not the case with the dual goal. In difficult trials, dual goals slowed down scanning processes again so that errors could be prevented. This new finding is particularly relevant for security domains, where both aspects have to be managed simultaneously.
