Tw o common tools in Linuxand UNIX-based environments are SSH for secure communications and sudo for performing administrative tasks. These are independent programs with substantially different purposes, but they are often used in conjunction. In this paper, we describe a weakness in their interaction and present our solution, public-key sudo. Public-key sudo1 is an extension to the sudo authen...

The study assessed the perceived effectiveness of agricultural extension methods used to disseminate improved technologies to rice farmers in kogi state, Nigeria. The specific objectives were to describe the socio – economic characteristics of the rice farmers, to assessed farmers level of contact with extension agents, perceived level of competence of extension agents to perform agricultural e...

The purpose of this study was to assess the process of extension program development in Iranian Agricultural Extension System (IAES). The research instrument was a structural questionnaire with close-ended questions which its validity and reliability was confirmed by using expert panel and Cranach’s alpha test, respectively. The target population of this research included all extension managers...

The limited audio bandwidth of narrowband telephone speech degrades the speech quality. This paper proposes a method that extends the bandwidth of telephone speech to the frequency range 0–300 Hz. The lowest harmonics of voiced speech are generated using sinusoidal synthesis. The energy in the extension band is estimated from spectral features using a Gaussian mixture model. The amplitudes and ...

there is undoubtedly general agreement that the efficiency of educational investments should he maximized through the managerial process as far as possible. agricultural extension is one of the crucial tasks in developing agricultural societies calling for considerable consumption of intellectual investment. the management of agricultural extension projects (aeps) however, needs careful pla...

Johnston (1978), Deegan and Packel (1979), and Holler (1982) proposed three power indices for simple games: Johnston index, Deegan-Packel index, and the Public Good Index. In this paper, methods to compute these indices by means of the multilinear extension of the game are presented. Furthermore, a new characterization of the Public Good Index is given. Our methods are applied to two real-world...

In this paper we develop an operational, quantitative method for the propagation of public perception. The model is presented as an extension of the culture-sanctioned social metric framework. We use the technique to model an extended version of the Spanish Steps flower selling scam, where a seller manipulates the belief of the clients and the public perception to pressure the clients to buy ov...

Today’s peer review process for scientific articles is unnecessarily opaque and offers few incentives to referees. The publishing process is unnecessarily inefficient and its results are only rarely made freely available to the public. We outline a comparatively simple extension of the arXiv.org preprint archive that addresses both of these problems: editors invite referees to write signed and ...
