... Survey sample population (n=23) includes energy experts associated with Energy and Natural Resources Association of Turkey and members of METU Graduates Association in order to satisfy diversity in participants ages. The survey was sent to energy experts involved with energy policy, energy planning and foreign direct investments. Ethical approval for conducting survey on human samples has been received from the Middle East Technical University Human Research Ethics Committee. The results are assessed using Two-way ANOVA method for the genders and professional backgrounds of the participants. The probability of a solution above the F-value (Pr>0.1) is used to test the {} hypothesis. The sample size is considered satisfactory to represent expert elicitation on climate change and energy policy issues however limited to assess their relations with environmental values and behaviors of participants.

... This study investigates the suitability of the Consensual Assessment Technique (CAT) in measuring creativity in the General Certificate of Secondary Education music compositions of student’s aged 15–16. For a music teacher, a key element of assessment is soliciting creative responses (products), which are authentic representations of musical creativity. The method of assessing music creativity here is categorized as summative assessment and is one of the most widely used and accepted methods of judging creative acts in situ. This project builds on empirical research regarding CAT’s use in music education. The CAT has become a standard research method in assessing creative products; however, it is not applied consistently across the field. This study examines whether music teachers (experts) and students (gifted novices) can use CAT to achieve an appropriate level of inter-rater agreement when judging a heuristic music composition for creativity. CAT has not been previously used to measure self and peer assessment with secondary school students in music composition. This study found music teachers and students to be highly reliable. This further supports music teachers’ as appropriate judges of student creativity and also acknowledges students who have received adequate support in creativity assessment to be reliable raters. Keywords: Music Composition, Consensual Assessment Technique (CAT), Self-Assessment, Peer Assessment, Creativity.

... The toxin HokB forms intermolecular disulfide bridges, which are essential for HokB pore formation and consequently the induction of persistence. Additionally, awakening of these persister cells relies on monomerization of the HokB toxin, combined with repolarization of the membrane.

... The dataset was used to investigate the potential impact of Tylosin and Enrofloxacin veterinary antibiotics on the seed germination percentage, root and shoot length, roots, and shoots over control percent, elongation, fresh weight, and dry weight of seedling. The uptake concentrations were detected and quantified using LC-NS/MS system to assist known the effect of antibiotics accumulation on the seed germination. The data were analyzed statistically to find out the significance of variation between treatments using IBM-SPSS statistic 25.

... This study reports the results of a multiyear program to predict direct executive elections in a variety of countries from globally pooled data.We developed prediction models by means of an election data set covering 86 countries and more than 500 elections, and a separate data set with extensive polling data from 146 election rounds.We also participated in two live forecasting experiments. Our models correctly predicted 80 to 90% of elections in out-of-sample tests. The results suggest that global elections can be successfully modeled and that they are likely to become more predictable as more information becomes available in future elections. The results provide strong evidence for the impact of political institutions and incumbent advantage. They also provide evidence to support contentions about the importance of international linkage and aid. Direct evidence for economic indicators as predictors of election outcomes is relatively weak. The results suggest that, with some adjustments, global polling is a robust predictor of election outcomes, even in developing states. Implications of these findings after the latest U.S. presidential election are discussed.
