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.

The analysis of the concept, properties and features of heterogeneous redundancy in modern complex ergatic systems, including those included in the situation centers (SC). On the basis of the qualimetric paradigm, the generalized analytical model of quality and optimization of quality by private, group, summary and aggregated quality indicators is justified. Practical ways of realization of the model and methods of optimization of the objects which are a part of SC and them as a whole at the expense of reduction of structural, functional and other types of redundancy under the obligatory condition of non-reduction of the required value of quality are given. On the example of the generalized sampling theorem when choosing the optimal value of the sampling frequency of the real bandpass signal, the criticality and significant influence on the redundancy of data in their further processing in the SC is shown.

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.
