Structural Modeling of Marine Reserves with Bayesian Estimation

Structural models can assess the effectiveness of fishery management prospectively and retrospectively. However, when only fishery-dependent data are available, structural econometric models are highly nonlinear in the parameters, and maximum likelihood and other extremum-based estimators can fail to converge. As a solution to these estimation challenges, we adapt Bayesian econometric methods to estimate a dynamic structural model of marine reserve formation. Using simulated data, we find that our approach is able to recover structural biological and economic parameters that classical estimation procedures fail to recover. We apply the approach to real data from the Gulf of Mexico reef-fish fishery. We test the effects of the Steamboat Lumps Marine Reserve on population growth and catchability for gag, a species of grouper. We find that after four years, the reserve has neither produced statistically significant losses in sustainable yield nor statistically significant gains in biological production.Marine reserves, marine protected areas, Bayesian econometrics, Markov Chain Monte Carlo, Environmental Economics and Policy, C11, Q22,

Bayesian Bioeconomics of Marine Reserves

We use Bayesian econometric methods to estimate dynamic bioeconomic models of marine reserve formation using simulated data and real data from the Gulf of Mexico reef fish fishery. We test the effects of reserves on fish growth and catchability.Resource /Energy Economics and Policy,

Software Manajemen Proyek Mechanical Electrical Di CV. Sumber Makmur Jaya Perkasa

CV. Sumber Makmur Jaya Perkasa atau yang biasa disingkat CV. SMJP ini bekerja di bidang Mechanical Electrical Contractor. Selama ini sistem yang digunakan oleh CV.SMJP masih menerapkan sistem manual. Rencana Anggaran Biaya (RAB), kurva “S”, pencatatan tender, dan jadwal proyek dilakukan secara manual dan dicatat dalam Microsoft Excel. Hal ini mengakibatkan membutuhkan waktu yang lama serta kurangnya efisiensi dalam analisis awal sebuah proyek yang diterima.Mengingat CV. SMJP ini mempunyai banyak proyek, penggunaan sistem yang masih manual dinilai kurang tepat dan tidak mendukung kebutuhan yang dibutuhkan Perusahaan. Berlatarbelakangkan hal tersebut, penulis ingin membuat sebuah sistem komputerisasi yang baru yang akan membantu jalannya Perusahaan dalam memanajemen proyeknya dengan berbasis web menggunakan PHP dan Mysql.Hasil atau output yang diperoleh dari sistem yang dibuat ini Antara lain, dapat membuat rencana anggaran dan realisasi secara otomatis, penghitungan biaya dan jadwal kerja yang membantu meminimalkan adanya pembengkakan dana dan kemoloran kerja, serta laporan-laporan yang dibutuhkan

Pericardium of the frog, Rana esculenta, is morphologically designed as a lymphatic space

The importance of the pericardium and the pericardial fluid (PF) in the control of cardiac function has emerged over the past few years. Despite the acknowledgment that amphibians are exposed to both dehydration and excessive water accumulation, nothing is known about their pericardial structure and the morphological basis of the PF formation. We have studied the parietal pericardium (PP) morphology in Rana esculenta by electron microscopy. SEM images of the inner surface, which lines the pericardial cavity, revealed the presence of large vesicles and many small circular openings. TEM observations showed that the PP is made up of an inner mesothelial lining, often constituted by two layers of very flat cells lying on a basal membrane and of regularly oriented collagen bundles. The PP outer surface is lined by a layer of flat cells, without a basal membrane. The mesothelial cells had overlapping boundaries with complex intercellular connections and a rich pool of caveolae opened in the direction of both the pericardial cavity and intercellular spaces. These cells indicate an intense intracellular and/or intercellular transfer of fluids and substances. The intraperitoneal injection of the idromineral hormone, Val5-ANG II, induced PP modifications, particularly evident at the level of the structures involved in the transmesothelial traffic. These lymphatic-like traits suggest that the frog PP represents a large lymphatic sac, subject to paracrine-endocrine remodeling, which can actively adjust the PF, influencing the composition and volume of the myocardial interstitial fluid. © 2003 Wiley-Liss, Inc

Perancangan Media Komunikasi Visual Produk Cokelat Vicco Kopkar Sekar Jember

Perancangan bertujuan untuk memperkenalkan produk lokal asli Jember, Indonesia, yaitu cokelat Vicco produksi kopkar Sekar kepada masyarakat kota Jember dan sekitarnya. Dengan harapan produk cokelat Vicco dapat menjadi panutan sebagai produk lokal yang membanggakan dan dapat mengedukasi masyarakat tentang manfaat coklat. Selain itu juga diharapkan dapat mendorong para petani cokelat Jember untuk ikut menciptakan produk cokelat lokal dan pada akhirnya menjadikan Jember sebagai salah satu kota sentra cokelat yang tentunya akan meningkatkan perekonomian masyarakat Jember. Untuk itu dibuat perancangan media komunikasi visual produk cokelat Vicco yang memiliki konsep modern, namun menggunakan unsur tradisional yang mencerminkan kota Jember seperti pola Batik Cokelat Jember, tari tradisional Jember, dan lainnya. Dan pembuatan maskot cokelat Vicco berupa figur petani cokelat agar semakin mudah diingat oleh masyarakat. Karya ini dapat menyampaikan identitas cokelat Vicco sebagai produk lokal Jember serta meningkatkan nilai brand dari produk cokelat Vicco

Developing a leadership identity: A grounded theory

This grounded theory study on developing a leadership identity revealed a 6-stage developmental process. The thirteen diverse students in this study described their leadership identity as moving from a leader-centric view to one that embraced leadership as a collaborative, relational process. Developing a leadership identity was connected to the categories of developmental influences, developing self, group influences, students' changing view of self with others, and students' broadening view of leadership. A conceptual model illustrating the grounded theory of developing a leadership identity is presented

A leadership identity development model: Applications from a grounded theory

This article describes a stage-based model of leadership identity development (LID) that resulted from a grounded theory study on developing a leadership identity (Komives, Owen, Longerbeam, Mainella, & Osteen, 2005). The LID model expands on the leadership identity stages, integrates the categories of the grounded theory into the LID model, and develops how the categories of the theory change across stages of the model. The model has implications for working with individuals as they develop their leadership identity and for facilitating groups as they develop empowering environments for shared leadership. Connections to related scholarship and stage-based implications for practice are explored
