Kalimantan Utara sebagai salah satu provinsi baru dan berada langsung di wilayah perbatasan dituntut untuk dapat mengembangkan sumberdaya alam yang dimiliki secara optimal utamanya di sektor pertanian dalam hal pemenuhan pangan beras yang semakin meningkat dan diharapkan dapat menjadi wilayah penyangga pangan untuk ibu kota baru nantinya.  Besar kecilnya produksi padi akan berpengaruh terhadap ketersediaan padi atau beras dan secara tidak langsung juga berdampak pada  kontribusinya terhadap Produk Domestik Regional Bruto (PDRB). Penelitian ini bertujuan untuk  mengetahui  prospek perkembangan komoditas padi di Provisi Kalimantan Utara ditinjau dari produksi, luas panen dan produktivitasnya; dan menganalisis kontribusi subsektor tanaman pangan terhadap PDRB bidang usaha pertanian, peternakan, perburuan dan jasa di Provisi Kalimantan Utara. Metode analisis yang digunakan adalah deskriptif kualitatif dengan pendekatan review literature dan penelusuran data sekunder berupa jenis data time series periode tahun 2013-2018. Analisis trend linier dan rumus proporsi digunakan Untuk mengetahui prospek dan kontribusi. Hasil analisis trend menunjukkan bahwa produksi padi cenderung mengalami trend penurunan yang diakibatkan olah trend penurunan luas panen, sedangkan produktivitasnya cenderung mengalami pelandaian (levelling off). Hal ini menunjukkan bahwa komoditas padi belum mampu dijadikan sebagai sektor unggulan di provinsi Kalimantan Utara. 2) kontribusi subsektor tanaman pangan terhadap PDRB bidang usaha pertanian, peternakan, perbutuan dan jasa di Provisi Kalimantan Utara sebesar 11.94 persen di bawah rata-rata kontribusi di sektor tersebut (15.09 persen) sehingga dapat disimpulkan bahwa Provinsi Kalimantan Utara belum bisa mengandalkan sub sektor tanaman pangan untuk peningkatan PDRB. Kata kunci: Padi, PDRB, Sektor Pertanian

AbstractThe occurrence of LDE-type flares in the last three cycles has been investigated. The Fourier analysis spectrum was calculated for the time series of the LDE-type flare occurrence during the 20-th, the 21-st and the rising part of the 22-nd cycle. LDE-type flares (Long Duration Events in SXR) are associated with the interplanetary protons (SEP and STIP as well), energized coronal archs and radio type IV emission. Generally, in all the cycles considered, LDE-type flares mainly originated during a 6-year interval of the respective cycle (2 years before and 4 years after the sunspot cycle maximum). The following significant periodicities were found:• in the 20-th cycle: 1.4, 2.1, 2.9, 4.0, 10.7 and 54.2 of month,• in the 21-st cycle: 1.2, 1.6, 2.8, 4.9, 7.8 and 44.5 of month,• in the 22-nd cycle, till March 1992: 1.4, 1.8, 2.4, 7.2, 8.7, 11.8 and 29.1 of month,• in all interval (1969-1992):a)the longer periodicities: 232.1, 121.1 (the dominant at 10.1 of year), 80.7, 61.9 and 25.6 of month,b)the shorter periodicities: 4.7, 5.0, 6.8, 7.9, 9.1, 15.8 and 20.4 of month.Fourier analysis of the LDE-type flare index (FI) yields significant peaks at 2.3 - 2.9 months and 4.2 - 4.9 months. These short periodicities correspond remarkably in the all three last solar cycles. The larger periodicities are different in respective cycles.

Purpose: Luria (1970) proposed the use of intersystemic reorganization to use an intact system to facilitate improvements in a damaged cognitive system. In this article, we review literature examining the effects of gesture as a modality to promote reorganization to improve verbal production in apraxia of speech and anomia. Methods: A gestural facilitation training paradigm is described and results of a recent systematic review of apraxia of speech treatment are reviewed. The interplay between apraxia of speech and anomia are considered in response to gestural facilitation training. Results & Conclusions: Gestural facilitation effects are strongest in individuals with moderate apraxia of speech. Several factors appear to mitigate the effects of gestural facilitation for verbal production, including severe apraxia of speech and semantic anomia. Severe limb apraxia, which often accompanies severe apraxia of speech, appears to be amenable to gestural treatment, providing improvements in gesture use for communication when verbal production gains are not evident.

Abstract. Aims: To discuss and review the latest research related to gambling expansion. Method: We completed a literature review and empirical comparison of peer reviewed findings related to gambling expansion and subsequent gambling-related changes among the population. Results: Although gambling expansion is associated with changes in gambling and gambling-related problems, empirical studies suggest that these effects are mixed and the available literature is limited. For example, the peer review literature suggests that most post-expansion gambling outcomes (i. e., 22 of 34 possible expansion outcomes; 64.7 %) indicate no observable change or a decrease in gambling outcomes, and a minority (i. e., 12 of 34 possible expansion outcomes; 35.3 %) indicate an increase in gambling outcomes. Conclusions: Empirical data related to gambling expansion suggests that its effects are more complex than frequently considered; however, evidence-based intervention might help prepare jurisdictions to deal with potential consequences. Jurisdictions can develop and evaluate responsible gambling programs to try to mitigate the impacts of expanded gambling.

Abstract We examined the use of smoothing to enhance the detection of response coupling from the activity of different response systems. Three different types of moving average smoothers were applied to both simulated interbeat interval (IBI) and electrodermal activity (EDA) time series and to empirical IBI, EDA, and facial electromyography time series. The results indicated that progressive smoothing increased the efficiency of the detection of response coupling but did not increase the probability of Type I error. The power of the smoothing methods depended on the response characteristics. The benefits and use of the smoothing methods to extract information from psychophysiological time series are discussed.
