Abstrak:Penelitian ini bertujuan untuk mengetahui gambaran keefektifan sekolah dilihat dari delapan standar nasional pendidikan. mengetahui tingkat ketecapaian keefektifan sekolahdilihat dari delapan standar nasional pendidikan dan mengetahui dari kedelapan standartnasional pendidikan butir mana disetiap standart yang masih perlu mendapatkan perhatiansecara serius. Metode penelitian yang digunakan adalahmetode survai yakni upayamengumpulkan informasi dari responden yang merupakan contoh dengan menggunakankuesioner yang terstruktur. Populasi dari penelitian ini adalah jumlah satuan pendidikanSekolah Mengengah Pertama (SMP) sebanyak 349 sekolah yang bersatatus sekolah negeriyang menyebar di wilayah eks karesidenan Surakarta. Sampel diambil sebanyak 172 sekolahdengan pendekatan area probability sampling. Instrumen yang digunakan dalam penelitian inimerupakan kuesioner tertutup dengan skala likert. Setelah data terkumpul kemudian dianalisisdengan pendekatan kuantitatif secara deskriptif. Hasil penelitian menunjukkan bahwa dilihatdari standar isi; standar proses; standar kompetensi kelulusan; standar pendidikan dan tenagakependididkan; standar sarana dan prasarana ; standar pengelolaan; standar pembiayaan; danstandar penilaian sudah cukup baik. Ketercapaian delapan standar nasional pendidikan seluruhsekolah sampel sudah mencapai tingkat yang cukup tinggi yakni di atas 90%, kendati masihada beberapa dari sub butir standart yang masih perlu lebih diperbaiki Abstract:The aim of this research is to discover the school effectiveness seen from eightcomponents of standards of national education. From these eight components, we will find outwhich components still need to be regenerated. This research is using survey method bystructured questionnaire to gather information from respondents. The population is 349Government Junior High Schools in a region of ex Surakarta Residence. Total of samples frompopulation is 172 schools, using area probability sampling approach. To collect the data, weused closed questionnaire with Likert scale as the instrument. After all data collected, then weanalyze it descriptively with quantitative approach. The result shown that all the componentsof standards of national education, including content standards; process standards;competence of graduates standards; educational standards and human resource standards;facilities standards; management standards; funding standards; and assesment standards arefairly good. The achievement of eight standards of national education from all sample schoolsalready achieved high level, i.e. above than 90%. But still there are several sub componentsneeds to be regenerated.

Abstract Background Understanding the burden of common mental health disorders, such as depressive disorder, is the first step in strengthening prevention and treatment in humanitarian emergencies. However, simple random sampling methods may lead to a high risk of coercion in settings characterized by a lack of distinction between researchers and aid organizations, mistrust, privacy concerns, and the overarching power differential between researchers and populations affected by crises. This case analysis describes a sampling approach developed for a survey study of depressive disorder in a Syrian refugee camp in Greece (n = 135). Discussion Syrian refugees face an extraordinarily high burden of depressive disorder during the asylum process (43%), necessitating population screening, prevention, and treatment. In order to preserve the informed consent process in this refugee camp setting, the research team developed a two-phase sampling strategy using a map depicting the geographical layout of the housing units within the camp. In the first phase, camp management announced a research study was being undertaken and individuals were invited to volunteer to participate. The participants’ container (housing) numbers were recorded on the map, but were not linked to the survey data. Then, in the second phase, the camp map was used for complementary sampling to reach a sample sufficient for statistical analysis. As a result of the two phases of the sampling exercise, all eligible adults from half the containers in each block were recruited, producing a systematic, age- and sex-representative sample. Conclusions Combining sampling procedures in humanitarian emergencies can reduce the risk of coerced consent and bias by allowing participants to approach researchers in the first phase, with a second phase of sampling conducted to recruit a systematic sample. This case analysis illuminates the feasibility of a two-phase sampling approach for drawing a quasi-random, representative sample in a refugee camp setting.

The loss of hematopoietic stem cell donation (HSCD) volunteers is widespread worldwide. This study analyzed the distribution characteristics of volunteer retention between the swab sampling approach and blood sampling approach. The Shanghai branch of the China Bone Marrow Donation Program conducted a telephone follow-up with 18,963 volunteers to understand volunteer retention. Multiple logistic regression was used to analyze the distribution characteristics of volunteer retention between two different sampling approaches, and a forest plot was used to observe the distribution trend. Only 32.37% of the volunteers could be contacted, and the loss of volunteers was severe. The volunteer retention is influenced by sampling approaches and demographic characteristics, and Shanghai natives, the highly educated, and students had better retention. The volunteer retention of the swab group was better among young people and technicians, while the volunteer retention of the blood sample group was lower among public officials and workers, and the volunteer retention in the blood sample group was more significantly affected by changes in population characteristics. To enhance the stability of volunteers, managers should improve the contact channels and frequency, expand the ratio of stable volunteers, strengthen volunteer education in the process of collecting blood samples, and respect individuals’ willingness.
