Efficient decision-making integrates previous experience with new information. Tactical use of misinformation can alter choice in humans. Whether misinformation affects decision-making in other free-living species, including problem species, is unknown. Here, we show that sensory misinformation tactics can reduce the impacts of predators on vulnerable bird populations as effectively as lethal control. We repeatedly exposed invasive mammalian predators to unprofitable bird odors for 5 weeks before native shorebirds arrived for nesting and for 8 weeks thereafter. Chick production increased 1.7-fold at odor-treated sites over 25 to 35 days, with doubled or tripled odds of successful hatching, resulting in a 127% increase in modeled population size in 25 years. We demonstrate that decision-making processes that respond to changes in information reliability are vulnerable to tactical manipulation by misinformation. Altering perceptions of prey availability offers an innovative, nonlethal approach to managing problem predators and improving conservation outcomes for threatened species.

Source Scaling

In this article, I propose a method for estimating the magnitude [Formula: see text] at which subduction megathrust earthquakes are expected to exhibit a break in magnitude scaling of both seismic source dimensions and earthquake ground motions. The methodology is demonstrated by applying it to 79 global subduction zones defined in the literature, including Cascadia. Breakpoint magnitude is estimated from seismogenic interface widths, empirical source scaling relations, and aspect ratios of physically unbounded earthquake ruptures and their uncertainties. The concept stems from the well-established observation that source-dimension and ground motion scaling decreases for shallow continental (primarily strike-slip) earthquakes when rupture exceeds the seismogenic width of the fault. Although a scaling break for megathrust earthquakes is difficult to observe empirically, all of the instrumentally recorded historical [Formula: see text] mega-earthquakes have occurred on subduction zones with [Formula: see text] (8.1–8.9), consistent with an observed break in source scaling relations derived from these same events. The breakpoint magnitudes derived in this study can be used to constrain the magnitude at which the scaling of ground motion is expected to decrease in subduction ground motion prediction equations.

Penggunaan teknologi saat ini dibutuhkan dalam bidang pelayanan publik. Seiring dengan bertambahnya kebutuhan masyarakat maka pemerintah sebagai penyedia layanan publik terus melakukan pembaruan terhadap perubahan pelayanan yang diberikan agar memudahkan masyarakat dalam mendapatkan layanan informasi. Salah satu penerapan e-government oleh Dinas Perhubungan Kota Surabaya adalah inovasi aplikasi TransportasiKu yang bertujuan untuk memberikan layanan informasi terkait lalu lintas dan transportasi umum yang ada di Surabaya secara terkini, praktis, lebih cepat dengan satu aplikasi yang memuat semua informasi melalui genggaman smartphone. Penelitian ini menganalisa menggunakan indikator measuring the quality of e-government from the user prespective (Kozák, 2018) dengan enam indikator yaitu ease of use, content and appearance of the information, reliability, citizen support, trust/security, support in completing forms. Penelitian ini menggunakan jenis penelitian deskriptif dengan metode kualitatif, teknik pengumpulan data wawancara, observasi, dokumentasi dan teknik analisa data yaitu pengumpulan data, reduksi data, penyajian data dan penarikan kesimpulan/verifikasi. Hasil penelitian ini menunjukkan bahwa aplikasi ini mendapat respon yang cukup baik dari masyarakat sebagai pengguna karena dapat memberikan layanan informasi yang dibutuhkan namun masih ada juga gangguan dalam penggunaannya. Indikator pertama, kemudahan penggunaan dirasa para pengguna sangat mudah digunakan untuk setiap saat. Indikator kedua, isi dan tampilan informasi yang dihadirkan sederhana dan lengkap. Indikator ketiga keandalan, pada aplikasi ini server yang digunakan masih kurang cukup. Indikator keempat dukungan masyarakat untuk halaman bantuan tidak tersedia hanya ada kolom komentar. Indikator kelima kepercayaan/keamanan, tidak menyertakan informasi pribadi sehingga aman. Indikator keenam dukungan dalam pengisian, formulir aplikasi ini berbasis informasi tanpa perlu pengisian formulir data para penggunanya. Kata Kunci : Pelayanan Publik, Inovasi, E-Government, TransportasiKu   The use of technology is currently needed in the field of public services. Along with the increasing needs of the community, the government as a public service provider continues to make updates to changes in the services provided to make it easier for the public to get information services. One of the applications of e-government by the Surabaya City Department of Transportation is the TransportationKu application innovation which aims to provide information services related to traffic and public transportation in Surabaya in an up-to-date, practical, faster way with one application that contains all information through the grip of a smartphone. This study analyzes using indicators measuring the quality of e-government from the user perspective (Kozák, 2018) with six indicators, namely ease of use, content and appearance of the information, reliability, citizen support, trust/security, support in completing forms. This research uses descriptive research with qualitative methods, interview data collection techniques, observation, documentation and data analysis techniques, namely data collection, data reduction, data presentation and conclusion / verification. The results of this study indicate that this application has received a fairly good response from the public as a user because it can provide the information services needed, but there are still disturbances in its use. The first indicator, ease of use, is felt by users to be very easy to use at any time. The second indicator, the content and display of the information presented is simple and complete. The third indicator is reliability, in this application the server used is still insufficient. The fourth indicator of community support for the help page is not available, only a comment column. The fifth indicator is trust / security, does not include personal information so it is safe. The sixth indicator of support in filling in this application form is information-based without the need to fill out user data forms.

Stress Drops

Abstract Source dimensions and stress drops of 30 small Parkfield, California, earthquakes with coda duration magnitudes between 1.2 and 3.9 have been estimated from measurements on short-period velocity-transducer seismograms. Times from the initial onset to the first zero crossing, corrected for attenuation and instrument response, have been interpreted in terms of a circular source model in which rupture expands radially outward from a point until it stops abruptly at radius a. For each earthquake, duration magnitude MD gave an estimate of seismic moment MO and MO and a together gave an estimate of static stress drop. All 30 earthquakes are located on a 6-km-long segment of the San Andreas fault at a depth range of about 8 to 13 km. Source radius systemically increases with magnitude from about 70 m for events near MD 1.4 to about 600 m for an event of MD 3.9. Static stress drop ranges from about 2 to 30 bars and is not strongly correlated with magnitude. Static stress drop does appear to be spatially dependent; the earthquakes with stress drops greater than 20 bars are concentrated in a small region close to the hypocenter of the magnitude 512 1966 Parkfield earthquake.

Teacher Reports

The Maximizing Academic Growth by Improving Communication (MAGIC) comprehensive classroom teacher and speech-language pathologist collaborative intervention program was developed and initially implemented in 12 kindergarten and first-grade classes to determine whether children receiving this language-enriched program performed significantly better than control peers on a curriculum-based test and on teacher reports of classroom communication. Results indicated that weekly classroom intervention resulted in significantly higher scores on the subtests of listening and writing for the children involved in the MAGIC program. Students in the treatment groups demonstrated significantly higher abilities in understanding vocabulary and cognitive-linguistic concepts in addition to increased writing skill development for producing relevant sentences with correct mechanics and spelling.
