It is well-established in the literature that particular design features of questionnaires affect the distribution and association of collected data. We present a survey approach called Crafty Questionnaire Design (CQED), that allows predictability and replicability of outcomes, expected of the natural sciences, to be achieved in the social sciences. Two independent proof-of-principle experimentsstudying interpersonal and institutional trust of Polish and Mexican students (n =1402), show that using different versions of a questionnaire offers predictably different outcomes. CQED promises a large gain in efficiency of research in terms of sample size required and number of replications needed. This knowledge can safeguard the social scientific researcher against unpleasant surprises and inconvenient results. Knowledge about the principles of CQED could also be a tool for editors as well as reviewers of social scientific journals to scrutinize the methodological soundness and improve the relevance of publications.

As the international community increases investment in agricultural adaptation to climate change in low and middle-income countries (LMICs), there is increasing demand to extract generalized knowledge claims about vulnerability from individual studies. If synthesis is to successfully produce sound generalized knowledge claims, relevant evidence must be possible to find and interpret. The format through which research in this field is now normally reported does not adequately support finding relevant evidence nor its interpretation. This opinion piece outlines and assesses three possible pathways for changing reporting practices in vulnerability research – standardization of methods, reporting checklists, and modularised reporting – in order to support the identification and synthesis of evidence. Rather than resolving these issues, this piece intends to open up the conversation about them.

Mobility is a top concern in current debates about a transition towards more sustainable patterns of consumption and production. In the European Union (EU) (2011), the transport sector accounts for...

Underrepresentation of women in senior positions is a persistent problem in universities worldwide, and a wide range of strategies to combat this situation is currently being contemplated. One such strategy is the introduction of a tenure track system, in which decisions to promote scientific staff to higher ranks are guided by a set of explicit and transparent criteria, as opposed to earlier situations in which decisions were based on presumably more subjective impressions by superiors. We examined the effect of the introduction of a tenure track system at Wageningen University (The Netherlands) on male and female promotion rates. We found that chances on being promoted to higher levels were already fairly equal between men and women before the tenure track system was introduced, and improved–more for women than for men–after the introduction of the tenure track system. These results may partly be explained by affirmative actions, but also by the fact that legacy effects of historical discrimination have led to a more competitive female population of scientists. In spite of these outcomes, extrapolations of current promotion rates up to 2025 demonstrate that the equal or even higher female promotion rates do not lead to substantial improvement of the gender balance at higher levels (i.e., associate professor and higher). Since promotion rates are small compared to the total amount of staff, the current distribution of men and women will, especially at higher levels, exhibit a considerable degree of inertia—unless additional affirmative action is taken.

Fish stocks experiencing high fishing mortality show a tendency to mature earlier and at a smaller size, which may have a genetic component and therefore long-lasting economic and biological effects. To date, the economic effects of such ecoevolutionary dynamics have not been empirically investigated. Using 70 y of data, we develop a bioeconomic model for Northeast Arctic cod to compare the economic yield in a model in which life-history traits can vary only through phenotypic plasticity with a model in which, in addition, genetic changes can occur. We find that evolutionary changes toward faster growth and earlier maturation occur consistently even if a stock is optimally managed. However, if a stock is managed optimally, the evolutionary changes actually increase economic yield because faster growth and earlier maturation raise the stock’s productivity. The optimal fishing mortality is almost identical for the evolutionary and nonevolutionary model and substantially lower than what it has been historically. Therefore, the costs of ignoring evolution under optimal management regimes are negligible. However, if fishing mortality is as high as it has been historically, evolutionary changes may result in economic losses, but only if the fishery is selecting for medium-sized individuals. Because evolution facilitates growth, the fish are younger and still immature when they are susceptible to getting caught, which outweighs the increase in productivity due to fish spawning at an earlier age.
