Latar Belakang: Stunting merupakan kondisi gagal tumbuh untuk mencapai pertumbuhan normal yang diakibatkan oleh status gizi kurang dalam periode waktu lama. Pencegahan serta penanganan stunting dapat dilakukan dengan meningkatkan pengetahuan ibu yang memiliki anak stunting agar tidak berlanjut pada anak selanjutnya. Pemberian edukasi pada ibu dapat dilakukan menggunakan metode brainstorming dan audiovisual. Tujuan: Mengetahui pengaruh pemberian edukasi dengan metode brainstorming dan audiovisual terhadap pengetahuan ibu tentang stunting di Desa Gununglurah, Cilongok, Kabupaten Banyumas. Metode: Desain penelitian adalah quasy experimental with time series design. Subjek penelitian terdiri dari 34 ibu yang memiliki balita stunting. Data pengetahuan ibu mengenai stunting dikumpulkan menggunakan kuesioner pretest dan posttest. Pemberian edukasi gizi mengenai stunting dilakukan dengan metode brainstorming (curah pendapat) menggunakan alat bantu leaflet. Pemberian edukasi gizi mengenai stunting dengan metode audiovisual dilakukan menggunakan film ilustrasi. Hasil: Rerata skor pengetahuan ibu pada saat pretest adalah 6,44±1,65 sedangkan skor pada saat posttest naik menjadi 7,38±1,76. Analisis statistik menggunakan uji beda Wilcoxon menunjukkan adanya perbedaan signifikan antara pengetahuan ibu mengenai stunting pada waktu sebelum dan sesudah dilakukan intervensi (p=0,009). Kesimpulan: Terdapat perbedaan pengetahuan ibu yang signifikan mengenai stunting pada waktu sebelum dan sesudah pemberian edukasi gizi dengan metode brainstorming dan audiovisual.

This study investigated whether homicides increased after protested police-involved deaths, focusing on the period after Michael Brown’s death in Ferguson in August 2014. It also tests for effects of legal cynicism by comparing effects in homicide and aggravated assault on the assumption that reporting of the latter is discretionary and police abuses may make communities reluctant to notify police. Using FBI data from 44 U.S. cities, homicide and assault rates from 2011 to 2019 were analyzed using an interrupted time series design and combined in a meta-analysis to calculate pooled effects. A meta-regression tested effect moderators including external investigations and city/county sociodemographic characteristics. With a conservative threshold of p ≤ .01, 21 of the 44 cities experienced a significant increase and one had a significant decrease. The pooled effect was a 26.1% increase in the homicide (99% CI: 15.3% to 36.8%). Aggravated assaults increased above baseline, though the effect was 15.2 percentage points smaller (99% CI: –26.7 to –3.6) than the effect in homicides. When outcomes were measured as percent change, there were no significant effect moderators, but when measured as absolute change, homicides increased to a greater extent when the death was subject to external investigation and in cities with higher Black populations, poverty rates, and baseline homicide rates. The findings suggest that protested police-involved deaths led to an increase in homicides and other violence due to the distrust fomented within the very communities whom police are meant to protect.

Polarization Extinction Ratio

We propose a new compact polarization beam splitter based on the self-collimation effect of two-dimensional photonic crystals and photonic bandgap characteristics. The device is composed of a rectangular air holes-based polarization beam splitting structure and circular air holes-based self-collimating structure. By inserting the polarization beam splitting structure into the self-collimating structure, the TE and TM polarized lights are orthogonally separated at their junction. When the number of rows in the hypotenuse of the inserted rectangular holes is 5, the transmittance of TE polarized light at 1550 nm is 95.4% and the corresponding polarization extinction ratio is 23 dB; on the other hand, the transmittance of TM polarized light is 88.5% and the corresponding polarization extinction ratio is 37 dB. For TE and TM polarized lights covering a 100 nm bandwidth, the TE and TM polarization extinction ratios are higher than 18 dB and 30 dB, respectively. Compared with the previous polarization beam splitters, our structure is simple, the size is small, and the extinction ratio is high, which meets the needs of modern optical communications, optical interconnection, and optical integrated systems.

Analyze Data

The Metropolitan Transit Authority of Harris County’s METROLift program implemented several revised fare policies on travel options available to eligible riders at the end of 2015 and the beginning of 2016. Fares changed on the METROLift paratransit single ticket and passes. A premium fare for the expanded service area and a smartcard—Freedom Q Card—that allows free ride on METRO’s fixed-route services were introduced. This paper documents analyses to determine the impact of the revised METROLift fare policies on travel patterns and travel frequency of METROLift riders. The authors used a linear segmented regression analysis to analyze data from an interrupted time series design. The results suggest that the revised fare policies controlled the growth of percentage of riders who use METROLift paratransit service in total ADA-eligible riders, while improved the awareness and willingness to use supplementary paratransit travel options, especially the fixed-route service in the base service area and the subsidy taxi service in the expanded service area.
