Analisis Gaya Kepemimpinan pada PT. Sinar Sarana Sukses
Penelitian ini bertujuan untuk mengetahui gaya kepemimpinan yang dilakukan atau diterapkan oleh direktur pada PT. Sinar Sarana Sukses Surabaya dengan menggunakan tiga jenis gaya kepemimpinan, yaitu: Gaya kepemimpinan otokratis, gaya kepemimpinan demokratis, dan gaya kepemimpinan kendali bebas. Jenis penelitian yang dilakukan adalah penelitian kualitatif. Obyek yang diteliti adalah gaya kepemimpinan pada PT. Sinar Sarana Suskes. Penulis menggunakan tiga informan untuk dianalisa dengan melakukan wawancara. Hasil dari penelitian ini membuktikan gaya kepemimpinan yang diterapkan oleh direktur di PT. Sinar Sarana Sukses didominasi oleh gaya kepemimpinan partisipatif, tetapi dalam situasi tertentu, direktur juga menggunakan gaya kepemimpinan otoriter
Analisa Karakteristik Campuran Aspal Emulsi Dingin Dan Perbandingan Stabilitas Aspal Emulsi Dingin Dengan Laston
Jalan pada umumnya menggunakan perkerasan lentur yaitu aspal. Aspal digunakan sebagai perekat antar agregatnya. Kebutuhan aspal di kota-kota besar di Indonesia semakin lama semakin meningkat, untuk pembuatan jalan baru maupun perbaikan jalan. Konstruksi menggunakan aspal panas menyebabkan polusi udara sehingga dilakukan penelitian pengganti aspal panas tersebut agar mengurangi polusi dengan aspal dingin yaitu aspal emulsi. Penelitian ini bertujuan untuk mengetahui pengaruh nilai sifat-sifatmarshall dari aspal emulsi tipe CSS-1h, CMS-1, dan CRS-1 serta membandingkan stabilitasnya dengan laston. Penelitian ini menggunakan kadar aspal emulsi 7%, 7,5%, 8%, 8,5%, 9% dan aspal laston dengan kadar 5%, 5,5%, 6%, 6,5%, 7% sesuai dengan ketentuan Binamarga. Hasil penelitian menunjukan bahwa aspal emulsi CSS-1h dapat dipakai sebagai perkerasan jalan. KARO aspal emulsi CSS-1h adalah 7% dengan nilai stabilitas 1259 kg lebih tinggi dibanding laston dengan KAO 6% dengan stabilitas 1033,35kg. Penggunaan aspal emulsi bisa diterapkan untuk perkerasan dengan tujuan Go Green
Pemanfaatan Limbah Kulit Singkong Termodifikasi Alkanolamida Sebagai Bahan Pengisi Dalam Produk Lateks Karet Alam: Pengaruh Waktu Vulkanisasi
The purpose of this research was to study the effect of drying time on the mechanical properties of natural rubber latex filled with cassava peel waste modified alkanolamide. Cassava peel is a waste, containing cellulose which is potential as fillers in natural rubber latex products. Cassava peel waste was dried and milled until the size of 100 mesh. Alkanolamide is one type of non-ionic surfactant which is synthesized from RBDPS (Refined Bleached Deodorized Palm Stearin) and diethanolamine. Alkanolamide has polar group which can modified cassava peel waste and make strong chemical bonding with natural rubber latex. The production of natural rubber latex products was started from pre-vulcanization at 70°C until the system was cured and the chloroform number has reached number 3. Natural rubber latex was formed into films by coagulant dipping and drying method at 120°C for 10 minutes and 20 minutes. Results show that longer drying time will improve the crosslink density and tensile strength of natural rubber latex products until the addition of 15 phr cassava peel waste powder
Examining the generalizability of research findings from archival data
This initiative examined systematically the extent to which a large set of archival research findings generalizes across contexts. We repeated the key analyses for 29 original strategic management effects in the same context (direct reproduction) as well as in 52 novel time periods and geographies; 45% of the reproductions returned results matching the original reports together with 55% of tests in different spans of years and 40% of tests in novel geographies. Some original findings were associated with multiple new tests. Reproducibility was the best predictor of generalizability—for the findings that proved directly reproducible, 84% emerged in other available time periods and 57% emerged in other geographies. Overall, only limited empirical evidence emerged for context sensitivity. In a forecasting survey, independent scientists were able to anticipate which effects would find support in tests in new samples
The psychological science accelerator’s COVID-19 rapid-response dataset
In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors and COVID-19 experience, geographical and cultural context characterization, and demographic information for each participant. Each participant started the study with the same general questions and then was randomized to complete either one longer experiment or two shorter experiments. Data were provided by 73,223 participants with varying completion rates. Participants completed the survey from 111 geopolitical regions in 44 unique languages/dialects. The anonymized dataset described here is provided in both raw and processed formats to facilitate re-use and further analyses. The dataset offers secondary analytic opportunities to explore coping, framing, and self-determination across a diverse, global sample obtained at the onset of the COVID-19 pandemic, which can be merged with other time-sampled or geographic data
A global experiment on motivating social distancing during the COVID-19 pandemic
Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-supportive message) or were restrictive and shaming (i.e., a controlling message) compared with no message at all. Results partially supported experimental hypotheses in that the controlling message increased controlled motivation (a poorly internalized form of motivation relying on shame, guilt, and fear of social consequences) relative to no message. On the other hand, the autonomy-supportive message lowered feelings of defiance compared with the controlling message, but the controlling message did not differ from receiving no message at all. Unexpectedly, messages did not influence autonomous motivation (a highly internalized form of motivation relying on one’s core values) or behavioral intentions. Results supported hypothesized associations between people’s existing autonomous and controlled motivations and self-reported behavioral intentions to engage in social distancing. Controlled motivation was associated with more defiance and less long-term behavioral intention to engage in social distancing, whereas autonomous motivation was associated with less defiance and more short- and long-term intentions to social distance. Overall, this work highlights the potential harm of using shaming and pressuring language in public health communication, with implications for the current and future global health challenges
