I analyze a model of electoral competition in which candidates’ need of credibility restricts their policy choice to a subset of the policy space, their ideology set. I focus on three party competition where candidates care about winning and their share of votes. I show that centrist parties are highly disadvantaged compared to leftist and rightist ones losing the election under a wide range of parameters. I also show that centrist parties’ winning opportunities increase under a run-off system.

I analyze a model of electoral competition with entry under the run-off rule. I consider both two- and multiple-party systems. The principal result is that two-party systems may prove stable under the run-off rule: I show that a continuum of equilibria exists in which only two parties enter and subsequent entry is deterred. This finding conflicts with the accepted wisdom on the run-off rule encapsulated by Duverger's Hypothesis. The results of the model are then reconciled with Duverger's Hypothesis and a more precise formulation is proposed.

Perubahan Pemanfaatan lahan yang begitu cepat, telah merubah pola-pola pengaliran permukaan (run-off) pada wilayah sub sistem sungai yang ada di daerah perkotaan. Permasalahan limpasan air permukaan dan genangan (storm watter), dipengaruhi oleh beberapa faktor, seperti masalah okupasi bantaran sungai, penimbunan rawa yang tidak sesuai, pengaruh pasang-surut sungai, yang mempengaruhi kapasitas sub sistem sungai pada wilayah bersangkutan (Putranto, 2016). Penelitian ini akan membahas isu spasial pada sistem aliran air permukaan dalam perencanaan tata ruang wilayah kota dengan menekankan integrasi aliran air permukaan (run-off) dan manajemen alokasi lahan. Metode yang digunakan dalam penelitian ini adalah melakukan analisis secara spasial menggunakan semua parameter Run-off dalam struktur database dengan memanfaatkan interface Sistem Informasi Manajemen Alokasi Lahan (SIMAL) yang dibangun untuk menguji besarnya puncak banjir menggunakan metode HSS Nakayatsu, dengan studi kasus sub sistem sungai Jakabaring, di Kota Palembang. Hasil yang diperoleh mampu melihat alih fungsi lahan rawa, yang dimanfaatkan untuk Kawasan Palembang Sport City dalam menghadapi Asian Games 2018 di Kota Palembang, telah menyebabkan genangan banjir pada wilayah sungai Kedukan, bagian dari Sub DAS Jakabaring, Kawasan Seberang Ulu, Kota Palembang, Indonesia. Berdasarkan Analisis menggunakan model hydrograft satuan Nakayatsu, terjadinya puncak banjir akan terjadi saat curah hujan mencapai lebih dari 120 mm/jam yang menyebabkan debit sungai kedukan mencapai hingga 400m3/det. Pembuatan danau buatan sebagai kolam retensi dan sekaligus sebagai venue olah raga, belum mampu mengurangi tinggi genangan yang terjadi sekitar 0,6 – 1,2 m dpl.

The ability of a bay and gulf ecosystems to self-purification was estimated and the current ecological state of the Sevastopol Bay in whole and the separated parts of the bay was given as an example. A zoning by type of anthropogenic impact subject to the water exchange with the open sea and an influence of the Chernaya River run-off were taken into account. A comparative analysis of assimilation capacity of the most environmentally disadvantaged part of the Sevastopol Bay (the Southern Bay) and the clean water area, bordering on the open sea, was carried out. The hydrodynamic regime of the Sevastopol Bay was described using numerical modelling. The prospect, opportunity and examples of the methodology for assessing the assimilation capacity of marine ecosystems are demonstrated.
