Sequential First-Price Auction with Randomly Arriving Buyers
Authors: Liu Shulin , Han Xiaohu 
Published: March 2018

AbstractIn this paper we reanalyze Said’s (2011) work by retaining all his assumptions except that we use the first-price auction to sell differentiated goods to buyers in dynamic markets instead of the second-price auction. We conclude that except for the expression of the equilibrium bidding strategy, all the results for the first-price auction are exactly the same as the corresponding ones for the second-price auction established by Said (2011). This implies that the well-known “revenue equivalence theorem” holds true for Said’s (2011) dynamic model setting.

<strong>English</strong><br />Mass tourism development directing all policies to support tourism in Bali causes water crisis and major agricultural base change. This paper aims to analyze of agricultural transformation process and water crisis taking place in Bali as well as its impacts on the socio-economic cultural life of the society and the future of tourism itself. Using the perspective of political ecology with review techniques, the obtained results are (1) tourism-oriented development policy brings a broad impact on the environment and the agricultural sector especially land conversion, labor, economy, and water resource utilization; (2) water crisis creates natural resource conflict among various stakeholders and tends to marginalize agriculture; (3) local subak institutional decay and it is potential to suppress natural resources and indigenous culture of Balinese society. In the long term, there is a potential that Bali loses its distinctive cultural appeal as the world tourism destination. Using political ecology perspective, it is suggested that Bali has to develop eco-tourism, agro-tourism, and culture-tourism as soon as possible.<br /><br /><br /><strong>Indonesian</strong><br />Pembangunan pariwisata massal yang mengarahkan semua kebijakan untuk mendukung pariwisata di Bali telah menyebabkan terjadinya krisis air dan perubahan basis utama pertanian. Tulisan ini bertujuan menganalisis proses transformasi pertanian dan krisis air yang terjadi di Bali serta dampaknya bagi kehidupan sosial-ekonomi-budaya masyarakat dan masa depan pariwisata itu sendiri. Menggunakan perspektif ekologi politik dengan teknik review diperoleh hasil bahwa (1) politik pembangunan berorientasi pariwisata membawa dampak yang luas terhadap lingkungan dan sektor pertanian khususnya alih fungsi lahan, ketenagakerjaan, perekonomian, hingga pemanfaatan sumber daya air; (2) terjadi krisis air yang menimbulkan konflik sumber daya alam antarberbagai stakeholder dan cenderung memarginalisasi pertanian; (3) terjadi peluruhan kelembagaan lokal subak dan potensial menekan sumber daya alam maupun kultur asli masyarakat Bali. Dalam jangka panjang, Bali potensial kehilangan daya tarik kultural yang khas sebagai destinasi pariwisata dunia. Menggunakan perspektif ekologi politik, disarankan pariwisata Bali lebih mengarah kepada pengembangan ekowisata, agrowisata, dan kulturwisata.

Os padrões de ensino das universidades ainda passam por processos de engessamento, e, é notável a falta de investimento e comprometimento das instituições com o retorno dos conhecimentos adquiridos para a sociedade em geral. Diante disso, são necessárias propostas metodológicas voltadas para vivências interdisciplinares, onde haja troca de experiências e conhecimentos entre o estudante e a comunidade. A fim de romper a barreira entre conhecimento acadêmico e conhecimento popular, o Grupo de Estudos da Amazônia (GEA) tem realizado nos últimos onze anos, atividades pedagógicas focadas no ensino através da vivencia. Em dois mil e quatorze a dois mil e quinze o GEA realizou um curso de iconografia da arte marajoara e uma vivência ao estado do Pará, envolvendo estudantes de diversos cursos da Universidade Federal Rural do Rio de Janeiro (UFRRJ) e também artesões. Através dos relatos dos participantes percebeu-se a ampliação do conhecimento teórico adquirido e uma grande conscientização dos estudantes perante a realidade regional. Dessa forma, reforça-se a importância de metodologiasde ensino voltadas a praticas de extensão.Palavras-chave: Práticas pedagógicas. Grupo de Estudos da Amazônia.

Synergistic Apoptotic Effects of Tocotrienol Isomers and Acalypha wilkesiana on A549 and U87MG Cancer Cells
Authors: Ibrahim Babangida Abubakar  , Su-Wen Lim  , Hwei-San Loh  
Published: March 2018

Recent studies suggested that combined treatment approaches can be used to improve anticancer potency and circumvent the limitations of high-dose tocotrienols administration. Acalypha wilkesiana is a medicinal plant that has been used as an adjunct treatment for cancers in traditional medicine. Herein, the effects of single and combined treatments of ?-, ?- and ?-tocotrienols and ethyl acetate extract (9EA) of Acalypha wilkesiana on lung (A549) and brain (U87MG) cancer cells were investigated. ?- and ?-tocotrienols exhibited higher potent antiproliferative effects against A549 (12.1 ?g/ml and 13.6 ?g/ml) and U87MG cells (3.3 ?g/ml and 5.2 ?g/ml) compared to ?-tocotrienols (9.4 ?g/ml and 92.4 ?g/ml), respectively. Whereas, 9EA induced potent antiproliferative effects against U87MG cells only (2.0 ?g/ml). Combined treatments of tocotrienols and 9EA induced a synergistic growth inhibition with up to 8.4-fold reduction in potent doses of ?-, ?- and ?-tocotrienols on A549 cells. Apoptotic features were also evidenced on A549 cells receiving single and combined treatments. The synergism may greatly improve the therapeutic outcome for lung cancer.

Kajian terbaru mencadangkan bahawa pendekatan gabungan rawatan boleh digunakan untuk meningkatkan potensi antikanser dan menghindari batasan pemberian tocotrienol dos tinggi. Acalypha wilkesiana adalah tumbuhan ubatan yang telah digunakan sebagai rawatan tambahan untuk kanser dalam perubatan tradisional. Di sini, kesan rawatan tunggal dan gabungan ?-, ?- dan ?-tocotrienols dan ekstrak etil asetat (9EA) daripada Acalypha wilkesiana pada paru-paru (A549) dan sel-sel kanser otak (U87MG) telah disiasat. ?- dan ?-tocotrienols menunjukkan kesan antiproliferatif yang lebih tinggi terhadap A549 (12.1 ?g/ml dan 13.6 ?g/ml) dan sel U87MG (3.3 ?g/ml dan 5.2 ?g/ml) berbanding ?-tocotrienols (9.4 ?g/ml), masing-masing. Sedangkan, 9EA merangsang kesan antiproliferatif yang kuat terhadap sel U87MG sahaja (2.0 ?g/ml). Rawatan terapi tocotrienols dan 9EA mencetuskan perencatan pertumbuhan sinergis sehingga pengurangan 8.4 kali ganda dalam dos yang kuat dari ?-, ?- dan ?-tocotrienols pada sel A549. Ciri-ciri apoptotic juga dibuktikan pada sel-sel A549 yang menerima rawatan tunggal dan gabungan. Sinergi ini boleh meningkatkan hasil terapeutik untuk kanser paru-paru.

Published: March 2018

Core Ideas
Corn yield response to plant density and N rate were dependent on yield environment.Agronomic optimal plant density and N rate were positively correlated to yield level.Yield to density within a yield environment was independent on year, country, and hybrid.Similarity in yield frequency data distributions lead to similar yield–factor responses.
Understanding the relationship of corn (Zea mays L.) yield responses to plant density and nitrogen (N) fertilization is critical to production decisions. The main objectives of this study were to (i) evaluate yield responses to plant density and fertilizer N rate at varying yields adjusting models considering a spatial component, (ii) perform a validation for the fitted models with an independent dataset, and (iii) identify key statistical parameters for the yield data distribution governing response models. Analyses were conducted with information from seven fields with 21 studies (one study per yield environment, with three environments per field) conducted from 2009 to 2017 in southern Brazil with geospatial data collected to evaluate yield response to plant density and fertilizer N rates (28911 data points) and one additional database with 12 field studies conducted from 2012 to 2015 in the US Midwest (1773 data points). Databases were divided into training and validation datasets. Field experiments evaluating both plant density and N rate were selected as training dataset. Key research findings were (i) yield–factor response models were dependent on yield environment and within a yield environment those models remained constant regardless the year, country, and hybrid for all evaluated fields, (ii) statistical models considering spatial correlation of the random errors outperformed those considering errors independent and identically distributed and, (iii) yield distribution with comparable 50% interquartile range and mode portrayed similar yield–factor relationship. In summary, fitting spatial yield–density models considering yield data distribution is critical to upscale site‐specific models to larger spatial domains.
Limited Dissolved Phosphorus Runoff Losses from Layered Double Hydroxide and Struvite Fertilizers in a Rainfall Simulation Study
Authors: Everaert Maarten , da Silva Rodrigo C. , Degryse Fien , McLaughlin Mike J. , Smolders Erik 
Published: March 2018

The enrichment of P in surface waters has been linked to P runoff from agricultural fields amended with fertilizers. Novel slow‐release mineral fertilizers, such as struvite and P‐exchanged layered double hydroxides (LDHs), have received increasing attention for P recycling from waste streams, and these fertilizers may potentially reduce the risk of runoff losses. Here, a rainfall simulation experiment was performed to evaluate P runoff associated with the application of recycled slow‐release fertilizers relative to that of a soluble fertilizer. Monoammonium phosphate (MAP), struvite, and LDH granular fertilizers were broadcasted at equal total P doses on soil packed in trays (5% slope) and covered with perennial ryegrass (Lolium perenne L.). Four rainfall simulation events of 30 min were performed at 1, 5, 15, and 30 d after the fertilizer application. Runoff water from the trays was collected, filtered, and analyzed for dissolved P. For the MAP treatment, P runoff losses were high in the first two rain events and leveled off in later rain events. In total, 42% of the applied P in the MAP treatment was lost due to runoff. In the slow‐release fertilizer treatments, P runoff losses were limited to 1.9 (struvite) and 2.4% (LDH) of the applied doses and were more similar over the different rain events. The use of these novel P fertilizer forms could be beneficial in areas with a high risk of surface water eutrophication and a history of intensive fertilization.Core Ideas
Granular struvite and LDH are known as slow‐release fertilizers (SRFs).
For the first time, struvite and LDH were tested in a runoff experiment.
42% of P in the MAP treatment was lost as DP due to runoff.
Struvite and LDH showed much lower loss (<3% of applied P) than MAP.
Applying SRFs can be considered in areas and times with a high risk of eutrophication.
Surface and Subsurface Tillage Effects on Mine Soil Properties and Vegetative Response
Authors: Angel H. Z. , Stovall J. P. , Williams H. M. , Farrish K. W. , Oswald B. P. , Young J. L. 
Published: March 2018

Core Ideas
Mine soil physical properties improve with increased tillage upon reclamation in the Gulf Coastal Plain.
Growth of loblolly pine seedlings increases with higher intensity tillage on reclaimed mined land.
Aboveground herbaceous cover and biomass increases with tillage on reclaimed mined land.
Soil compaction is an important concern for surface mine operations that require heavy equipment for land reclamation. Excessive use of rubber‐tired equipment, such as scraper pans, may cause mine soil compaction and hinder the success of revegetation efforts. However, information is limited on management strategies for ameliorating the potential compacting effects of scraper pans, particularly during site preparation for loblolly pine (Pinus taeda L.) plantations. Three forms of tillage and one control were replicated five times on surface mined land in the west Gulf Coastal Plain: no tillage (NT), disking (D), single‐ripping + disking (R+D), and cross‐ripping + disking (CR+D). Mine soil physical properties were investigated at 0 to 30, 30 to 60, and 60 to 90 cm. Percent cover and aboveground biomass of an herbaceous winter cover crop, and survival and growth of loblolly pine seedlings were assessed after one growing season. Herbaceous species biomass was highest on the R+D and CR+D plots and lowest on the NT control. Pine seedling survival was highest on the tilled plots (>90%) compared to NT (85%). The highest intensity combination tillage treatment (CR+D) was superior in terms of lowering soil bulk density (mean 1.36 Mg m–3) and soil strength (mean 2220 kPa) and increasing pine seedling volume index growth (mean 32 cm3). Surface tillage (D) alone improved herbaceous cover and pine seedling survival, while CR+D provided the most favorable responses in mine soil physical properties and vegetative growth.
