Changes in agricultural yields due to climate change will affect land use, agricultural production volume, and food prices as well as macroeconomic indicators, such as GDP, which is important as it enables one to compare climate change impacts across multiple sectors. This study considered five key uncertainty factors and estimated macroeconomic impacts due to crop yield changes using a novel integrated assessment framework. The five factors are (1) land-use change (or yield aggregation method based on spatially explicit information), (2) the amplitude of the CO2 fertilization effect, (3) the use of different climate models, (4) socioeconomic assumptions and (5) the level of mitigation stringency. We found that their global impacts on the macroeconomic indicator value were 0.02–0.06% of GDP in 2100. However, the impacts on the agricultural sector varied greatly by socioeconomic assumption. The relative contributions of these factors to the total uncertainty in the projected macroeconomic indicator value were greater in a pessimistic world scenario characterized by a large population size, low income, and low yield development than in an optimistic scenario characterized by a small population size, high income, and high yield development (0.00%).

The topic of the lesson used was energy. This type of research used descriptive quantitative approach.Data collection techniques use tests which included aspects of context, content, and process. While the data analysis technique used descriptive statistics. The results of the investigation found that the scientific literacy ability of class X students in Senior High School 1 Kendari on the indicator aspect of content where the first indicator was the change in energy obtains a percentage of 70.83% with a sufficient category. Then for alternative fuel indicators got a percentage value of 79.72% with a good category. As for the energy supply molecular indicator, it s a percentage of 33.75% with a very low category. The ability of scientific literacy in class X students in Senior High School 1 Kendari in the process aspect indicator where the first indicator identifies scientific issues obtains a percentage value of 50.13% with low. Then, to explain scientific phenomena acquire indicator value percentage of 34.62% with a very low category. As for the indicator using scientific evidence obtained percentage value of 52.69% with a lower category. While the scientific literacy ability of class X students in Senior High School 1 Kendari on the indicator of context aspects where the first indicator of energy application in the technology field obtained a percentage value of 89.72% with a very good category. Then for the energy indicator in improving environmental quality, the percentage value is 29.16% with a very low category. To obtain the energy impact indicator value percentage of 17.08% with a very low category. Keywords—Science literacy, Physics learning

This study aims to "know the effect of teacher shadow competence on indicator value ", formulation of the problem "how the effect of teacher shadow competence on indicator value ". Inclusion schools are public schools that combine regular students with ABK students. In general, teacher competence is divided into four, namely competence: 1) pedagogy, personality, social and professional. But for shadow teachers there are additional competencies that should be mastered that is performative competence. Requirements for teachers to master performative competence are to understand and understand the circumstances surrounding the environment, plan goals and strategies, transmit positive values to the environment, create message intelligence. The assessment of shadow teachers at MIT Ar-Roihan has the name of the indicator value, consisting of eight aspects of the assessment, namely: 1) making learning tools, 2) learning implementation, 3) learning evaluation, 4) reporting learning outcomes, 5) attitudes, 6) making media, 7) additional tasks, and 8) special achievements. This research is a correlational quantitative research, location at MIT Ar-Roihan Lawang, Malang Regency. The sample of the research used total sampling technique with 37 teachers. Data analysis using linear regression technique. From the results, obtained correlation coefficient value R = 0,596 and included medium category. From the table "ANOVA", obtained Regression value is 0.000 and <0,05 then concluded "There is a significant influence between teacher shadow competence (X) on indicator value (Y)".

In this work, it was matter of determining the species characteristics of the delta of the Oueme through the illustration of their indicative value. Sampling was carried out in eight heterogeneous stations covering the periods of flood and low water. The various indices including that of biserial correlation IndVal (Indicator Value Index) and the cover sites of groups were used as the basis of analysis. The results showed that the selected significant indicative species are highly correlated and have a preference for stations full of organic and mineralized matter. Also, taxa have a marked preference for the flood season (21 taxa) than low water (5 taxa). Most characteristic taxa highlighted by this procedure should be useful to assess changes in quality of the plants studied. Most taxa characteristics highlighted by this procedure should be useful to assess changes in quality of the plants studied.

In 2006–2007 larval caddisfly assemblages of a semi-natural calcareous stream (Örvényesi Creek) were studied. Characteristic sections can be detected along the whole length of the stream, which passes through diverse types of vegetation, resulting in highly heterogeneous aquatic habitats. Based on an annual survey of different aquatic habitats, our aims were to give an overview of the spatio-temporal distribution of the larval caddisfly assemblages in the Örvényesi Creek and to find indicator species characterizing different sections of the stream. In order to show the spatio-temporal patterns, samples were collected at 7 locations with different streambed morphology, from spring to the mouth of the stream. Caddisfly larvae were collected in every 3rd week during a 1 year period using the “kick and sweep” method. Multivariate analyses were carried out to explore the spatio-temporal structure of caddisfly assemblages. The indicator value method was applied to detect indicator species for different sections of the stream. A rich caddisfly fauna (20 taxa) was found in the Örvényesi Creek. Fast-running and relatively cold-water hypocrenal sections were characterized by Beraea maurus and Apatania muliebris at high indicator value. Three Limnephilidae species (Limnephilus rhombicus, Limnephilus lunatus and Glyphotaelius pellucidus) were identified as significant indicator species for slow flowing, lentic habitats. Along the length of the stream, distinctive spatial and temporal changes were detected in the distribution of the caddisfly assemblages. These changes were mainly connected to variations in morphology of the streambed, phenology of individual taxa, extreme weather conditions and human impacts.
