This study aims to reduce body dissatisfaction in women in the period of emerging adulthood with gratitude intervention. Subjects of this study consisted of two people experiencing body dissatisfaction. This study used a quasi-experimental methods. Data making assessment conducted by interview, observation, body shape questionnaire, and gratitude questionnaire. Statistically the result showed that there is no gratitude intervention can not reduce body dissatisfaction (p= 0,180 > 0,05), but descriptive analysis showed that gratitude intervention gave positive result by reducing body dissatisfaction. The characteristic of body dissatisfaction are not confidence, never satisfied with their body, comparing their self to others who has more ideal body, sensitive, have a need for support and happy to get a compliment.Keywords : body dissatisfaction, gratitude intervention

Learning science in SMPN 1 Padang has been running pretty well in accordance with the curriculum of 2013. However, there are still shortcomings in the aspect of attitude. Such as low self-care among others, mutual esteem is very low when friends come forward, attitudes tend to be selfish and apathetic attitude towards the environment, resulting in low competence of the social attitudes of learners. One of the ways that teachers can do is to implement cooperative learning model Numbered Head Together (NHT). This study aims to determine the effect of cooperative learning model Numbered Head Together (NHT) the competence of the social attitudes of students of class VII SMPN 1 Padang. This study was an experimental study with a quasi-experimental methods (quasi-experimental). The study population was the students of class VII SMPN 1 Padang. Sampling was done by purposive sampling with learners VII.D class as the control class and the class as a class experiment VII.E. The instrument used is the observation sheet attitude competence of learners. The result shows that there are improvement of students social attitude competence after using NHT in class VII SMPN 1 Padang. Factors include are discussed.

This research is a quantitative research using quasi-experimental methods. This study uses the research design of one group pretest-posttest design. The population is male students of SMP Negeri 8 Kaur and the sample is 30 students with totalsampling techniques. The instrument used in this study was a test used in the pre test and posttest. After the treatment process, the average pretest data is 10.52 and the average posttest is 9.42. Based on the statistical test obtained tcount of 3,28 and t table with a 5% significance level of 1.69913. Because tcount> ttable, it can be concluded that the working hypothesis is acceptable because it is significant. This means that beach load-based leg muscle training has an effect on increasing the 50 meter run performance. Keywords: Leg Muscle, Beach Based Load, 50 Meter Running Ability

 Many studies in master psychology and professional psychology study programs used quasi-experimental methods, but there was no reference regarding quasi-experiments written in Indonesian. This article will fill in the blanks on reference to quasi-experimental methods. The article explains quasi-experimental design or non-randomized experimental design. According to Campbell quasi experimental design is divided into four types, namely (a) quasi-experimental design without control group or pretest, b) quasi experimental design with control group and pretest, c) time series design, and d) regression discontinuity design. Each type was broken down into a more specific design.

Background/Context Parents, policymakers, and researchers uphold that missing school has negative implications on schooling success, particularly for students in urban schools. However, it has thus far been an empirical challenge within educational research to estimate the true effect that absences have on achievement outcomes. This study addresses this issue by applying multiple quasi-experimental methods and, subsequently, contributes a more accurate understanding of the pervasive, negative effects of missing school. Purpose/Objective/Research Question/Focus of the Study The purpose of this study is to determine the effects of individual-level absences on individual-level standardized testing achievement (reading and math) in an urban school district. Population/Participants/Subjects The dataset compiled for this study is multilevel and longitudinal and is comprised of five elementary school cohorts within the School District of Philadelphia, for a total of N=20,932 student observations over three academic years. Individual student records were linked to teacher, classroom, and school administrative data as well as to census residential-block neighborhood information. Research Design This study combines secondary data analyses and quasi-experimental methods. This study begins with a baseline, linear model of achievement, where the dependent variables are Stanford Achievement Test Ninth Edition (SAT9) reading and math scores. To address issues pertaining to omitted variable bias, this study employs three methods: fixed effects, value-added, and instrumental variable models. Findings Consistently across all methods employed in this study, the results indicate a potentially causal, detrimental negative effect of absences on both reading and math standardized achievement. The effects remain significant even after accounting for additional student, neighborhood, teacher, classroom, and school factors. Conclusions/Recommendations This study demonstrates that after accounting for omitted variable bias in multiple capacities, the negative relationship between absences and achievement is even more detrimental than reported in previous research. With a more detailed and realistic prediction of the negative ramifications of missing school, it now becomes possible to develop data-driven educational policy.

The Relationship

Existing evidence clearly supports an empirical connection between offending and victimization. Often called the “victim–offender overlap,” this relationship holds for both sexes, across the life course, and across a wide range of countries and cultural environments. In addition, the relationship is sustained regardless of the study sample and statistical methods applied in the analyses of the sample data. However, there has yet to be a study that examines this relationship for violent and property crime using quasi-experimental methods accounting for a wide range of potential confounders including individual differences and cultural contexts. This study subjects the victim–offender relationship to testing through propensity score matching for both violent and property crimes using an international dataset. The results show that previous violent and theft offending increases the odds of victimization when matching on individual and contextual factors. This finding supports previous literature and suggests that delinquent behavior may act as a “switch” that exposes one to subsequent violent and theft victimization.

The Impact

Private car-use is a major contributor of greenhouse gases. Car-sharing is often hypothesised as a potential solution to reduce car-ownership, which can lead to car-sharing users reducing their car-use. However, there is a risk that car-sharing may also increase car-use amongst some users. Existing studies on the impacts of car-sharing on car-use are often based on estimates of the users’ own judgement of the effects; few studies make use of quasi-experimental methods. In this paper, the impact of car-sharing on car-ownership and car-use in Flanders, Belgium is estimated using survey data from both sharers and non-sharers. The impact on car-use is estimated using zero-inflated negative binomial regression, applied to matched samples of car-sharing users and non-users. The results show that the car-sharing may reduce car-use, but only if a significant number of users reduce their car-ownership. Policy intervention may therefore be required to ensure car-sharing leads to a reduction in car-use by, for example, discouraging car-ownership. Further research using quasi-experimental methods is required to illuminate whether the promise of car-sharing is reflected in reality.
