Different Routes to Explain Pro-Environmental Behavior: an Overview and Assessment
No full textA variety of theoretical approaches have been taken in an attempt to understand, explain, and promote pro-environmental behavior. The present article gives an overview, including speci c applications, and identi es and discusses various strategies used by researchers to deal with the availability of di erent approaches. The overview includes elementary rational choice theory, the theory of planned behavior, norm-activation theory, theories of habitual behavior, and theories within a social dilemma framework. Strategies identi ed are 'extending existing theories by single explanatory factors', 'comparing theories' in a competitive manner, and 'combining theories' in an integrative manner. It is argued that research would bene t from more standardization in empirical applications, from more competitive theory testing as opposed to integrative theory testing, and from an evaluation of approaches on theoretical grounds as opposed to focusing solely on empirical performance

Determinants of protest responses in environmental valuation: A meta-study
No full textCertain design characteristics of stated preference surveys are often linked to protest responses The dichotomous choice format for example is said to result in fewer protest responses However not much is known at present about the relationship between survey characteristics and the level of protesting Only partial analysis comparing for instance the influence of different payment vehicles on protesting has been conducted to date This paper analyses the determinants of protest responses using 254 samples derived from 157 environmental valuation studies Determinants include the elicitation format the payment vehicle the survey method and the geographical origin Results of bivariate and multivariate analyses confirm some of the propositions presented in the literature such as a higher number of protesters when entrance fees are used as a payment vehicle However many of the characteristics included in the analysis do not significantly impact protesting Another result is that reporting on identification and treatment of protest responses in subsequent analysis is inadequate in the majority of studies and would benefit from some standardisation (C) 2010 Elsevier BV All rights reserve
Effect of sugar beet variety resistance on the disease epidemiology of Cercospora beticola
No full textAbstract BACKGROUND Cercospora leaf spot (CLS), caused by Cercospora beticola , is the most destructive foliar disease in sugar beet. CLS is conventionally controlled with fungicide, but the emergence of fungicide‐resistant populations reinforces the importance of developing and cultivating resistant varieties. Understanding the dynamics of CLS in different varieties is hence essential for sustainable CLS management. RESULTS Field experiments (2022 and 2023) with four sugar beet varieties possessing different resistant properties were conducted to describe the relationship between the variety resistance and the disease epidemiology of C. beticola . For this purpose, spore flight and disease progression were assessed on a weekly basis. Disease severity (DS) and disease incidence (DI) were delayed in resistant varieties compared to the susceptible and moderately susceptible ones. This finding was further confirmed by a model‐based analysis of DS and DI for all varieties. Weekly spore flight monitoring during the vegetation period showed a similar tendency of reduced spore quantity by the resistant varieties. This was probably due to the lower DS, as no differences were found when the amount of fungal DNA was determined in individual lesions from the different varieties. Analysis of relative yield loss further confirmed the advantage of growing resistant varieties. CONCLUSION Our results highlight that resistant varieties delay disease onset resulting in less severe symptoms and reduced spore flight. We also proved that aerial spore flight intensity could reflect the resistant property of each variety. These results provide a deeper insight into the interaction between variety resistance and CLS epidemiology, emphasizing variety‐specific CLS management. © 2025 The Author(s).

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
