Marketing of fishing gear materials and fishing gear making in parts of Kainji Lake basin

The importance of fishing gear in fishing cannot be over-emphasized; as without it fish cannot be obtained. The method used to catch fish affects the condition in which the product is landed. This means that a bad-catching method would produced bad fish to the consumer. To achieve the goal of self-sufficiency in fish production in Nigeria, there is need to address the lingering problems of fishing gear and craft technology, especially in terms of availability of materials and their cost. The sale and making of fishing gear materials are two areas of fisheries, which are yet to be exploited by the general public as forms of businesses for livelihood. The study is conducted in villages around the lower part of Kainji Lake, towards the dam, including New Bussa. It reveals that only the fishermen themselves are involved in making their own fishing gears while those involved in the selling of fishing gear materials like the sheet netting, ropes, twines, floats, sinkers etc are business men and women who may not have any experience of fishing. Also considered in the study is the art of making fishing crafts like the canoe and gourd. Very few entrepreneurs are involved and they are so skilled that each is specialized in the making of only one kind of craft or gea

Completing Partial Packings of Bipartite Graphs

Given a bipartite graph $H$ and an integer $n$, let $f(n;H)$ be the smallest integer such that, any set of edge disjoint copies of $H$ on $n$ vertices, can be extended to an $H$-design on at most $n+f(n;H)$ vertices. We establish tight bounds for the growth of $f(n;H)$ as $n \rightarrow \infty$. In particular, we prove the conjecture of F\"uredi and Lehel \cite{FuLe} that $f(n;H) = o(n)$. This settles a long-standing open problem

"Locational Disadvantage and Losses from Trade: Three Regions in Economic Geography"

We show that how spatial evolution is different between the two representative models of economic geography: Krugman (1991 JPE) and Ottaviano et al. (2002 IER). We analyze the impacts of falling transport costs on the spatial distribution of economic activities and welfare for three regions located on a line. In the former model, the central region always has locational advantage and manufacturing workers gain from trade. In the latter model, however, the opposite is true when markets are opened up to trade. This is because the price competition is so keen in the central region that manufacturing sector moves to the peripheral regions, which aggravates the social welfare. We then show that when goods are close substitutes and share of manufacturing is of an intermediate level, the manufacturing activities completely disappears from the central region leading to a full agglomeration in one peripheral region.

New Bounds for Permutation Codes in Ulam Metric

New bounds on the cardinality of permutation codes equipped with the Ulam distance are presented. First, an integer-programming upper bound is derived, which improves on the Singleton-type upper bound in the literature for some lengths. Second, several probabilistic lower bounds are developed, which improve on the known lower bounds for large minimum distances. The results of a computer search for permutation codes are also presented.Comment: To be presented at ISIT 2015, 5 page

FAKTOR-FAKTOR YANG MEMPENGARUHI KEPUASAN KONSUMEN DALAM MENGGUNAKAN JASA INTERNET PADA WARNET JAVA NET DI SURABAYA

Pada kemajuan zaman dewasa ini atau yang sering disebut era globalisasi, batasan-batasan dan wilayah satu tempat dengan wilayah yang lain hampir tidak ada.

Tujuan penelitian adalah untuk mengetahui dan menganalisis pengaruh secara simultan antara harga, pelayanan, dan fasilitas terhadap kepuasan konsumen. Dan untuk mengetahui dan menganalisis pengaruh secara parsial antara haga, pelayanan, dan fasilitas terhadap kepuasan konsumen dalam menggunakan jasa internet. Populasi dalam penelitian ini adalah pelanggan warnet Java Net Di Surabaya tidak diketahui. Penelitian ini menggunakan sampel sebanyak 100 orang yang diambil dengan menggunakan teknik penarikan sampel Purpossive sampling. Jenis data dalam penelitian ini adalah data primer. Sedangkan teknik pengumpulan data menggunakan kuisioner. Selanjutnya data dianalisis menggunakan teknik regresi linier berganda. Berdasarkan analisis data disimpulkan bahwa 1) Hasil uji F menunjukkan bahwa variabel harga, pelayanan dan fasilitas secara simultan berpengaruh nyata terhadap kepuasan konsumen, 2) Hasil uji t menunjukkan bahwa secara parsial variabel harga, pelayanan dan fasilitas berpengaruh terhadap kepuasan konsumen, 3) Dari seluruh variabel bebas yang berpengaruh terhadap kepuasan konsumen adalah variabel pelayanan yang memiliki pengaruh paling dominan
