Weed vegetation of cereal crops in Tajikistan (Pamir Alai Mts., Middle Asia)
2013
The paper presents results of investigations of weed vegetation conducted in crop fields, in Tajikistan (Middle Asia) - one of the world cradles of the weed flora. The study has been based on 299 phytosociological relevés obtained in various geobotanical regions of the country in 2009-2012. In the examined vegetation patches 469 vascular plant species were noted. Many of the recorded species are widespread weeds. However, there were also some rare and endemics taxa (e.g. Prangos pabularia, P. saraw-schanica and Thlaspidium thlaspi) observed in the sample plots. The collected material presents probably, the majority of the variability among the weed communities of crop cultivations in the Mi…
Joint Subcarrier and Phase Shifts Optimization for RIS-aided Localization-Communication System
2022
Joint localization and communication systems have drawn significant attention due to their high resource utilization. In this paper, we consider a reconfigurable intelligent surface (RIS)-aided simultaneously localization and communication system. We first determine the sum squared position error bound (SPEB) as the localization accuracy metric for the presented localization-communication system. Then, a joint RIS discrete phase shifts design and subcarrier assignment problem is formulated to minimize the SPEB while guaranteeing each user’s achievable data rate requirement. For the presented non-convex mixed-integer problem, we propose an iterative algorithm to obtain a suboptimal solution …
Data from: New insights on water buffalo genomic diversity and post-domestication migration routes from medium density SNP chip data
2019
The domestic water buffalo is native to the Asian continent but through historical migrations and recent importations, nowadays has a worldwide distribution. The two types of water buffalo, i.e., river and swamp, display distinct morphological and behavioral traits, different karyotypes and also have different purposes and geographical distributions. River buffaloes from Pakistan, Iran, Turkey, Egypt, Romania, Bulgaria, Italy, Mozambique, Brazil and Colombia, and swamp buffaloes from China, Thailand, Philippines, Indonesia and Brazil were genotyped with a species-specific medium-density 90K SNP panel. We estimated the levels of molecular diversity and described population structure, which r…
Host Searching by Egg Parasitoids: Exploitation of Host Chemical Cues
2010
Insect parasitoids are considered “keystone species” in many ecosystems in terms of biodiversity, ecological impact and economic importance (Vinson 1985, LaSalle and Gauld 1993, Hawkins et al. 1999). In the last decades, several reviews have been published on the relationships among plants, hosts and parasitoids, which reflect a strong interest in these insects both as models for behavioral ecologists and as important organisms for classical and applied biological control programs (Hawkins et al. 1999, Vet 1999, Bale et al. 2008). The majority of these studies have considered the larval parasitoid s, besides the extensive use of egg parasitoids in biological control (Hawkins et al. 1999). I…
Estimating Regional Input Coefficients and Multipliers: The Use of FLQ is Not a Gamble
2014
Flegg A. T. and Tohmo T. Estimating regional input coefficients and multipliers: the use of FLQ is not a gamble, Regional Studies. This paper re-examines the Finnish evidence presented by Lehtonen and Tykkylainen on the use of location quotients (LQs) in estimating regional input coefficients and multipliers. They argue that the choice of an LQ-based method is a gamble and that there is no single method that can be recommended for general use. It is contended here that this evidence is erroneous and that the FLQ (Flegg's location quotient) yields results far superior to those from competing formulae, so it should provide a satisfactory way of generating an initial set of input coefficients.…
Government policy failure in public support for research and development
2014
peer-reviewed Promoting Research and Development (R&D) and innovative activity is a key element of the EU Lisbon Agenda and is seen as playing a central part in stimulating economic development. In this paper we argue that, even allowing for benevolent policy-makers, informational asymmetries can lead to a misallocation of public support for R&D, hence government policy failure, with the potential to exacerbate preexisting market failures. Initially, we explore alternative allocation mechanisms for public support, which can help to minimize the scale of these government policy failures. Of these mechanisms (grants, tax credits, or allocation rules based on past performance), our results sug…
The regionalization of national input-output tables : A study of South Korean regions
2018
This paper uses survey‐based data for 16 South Korean regions to refine the application of Flegg's location quotient (FLQ) and its variant, the sector‐specific FLQ (SFLQ). These regions vary markedly in terms of size. Especial attention is paid to the problem of choosing appropriate values for the unknown parameter δ in these formulae. Alternative approaches to this problem are evaluated and tested. Our paper adds to earlier research that aims to find a cost‐effective way of adapting national coefficients, so as to produce a satisfactory initial set of regional input coefficients for regions where survey‐based data are unavailable. Este documento utiliza datos basados en encuestas de 16 reg…
Competing institutional logics in Soviet industrial location policy
2018
The Soviet legacy has been widely demonstrated to have had negative impacts on the regional and economic development of Russia. This article studies the mechanisms of competing institutional logics in Soviet industrial location policies as a source of this adverse heritage. The results indicate that prolonged competition between three institutional logics complicated the adoption and practice of consistent industrial location strategies and contributed to structural problems in economic geography. An analysis of Soviet institutional logics demonstrates parallel forms of competition and coexistence with findings from other institutional environments, paving the way for a broader theoretical …
Diversity begets diversity: A global perspective on gender equality in scientific society leadership.
2018
Research shows that gender inequality is still a major issue in academic science, yet academic societies may serve as underappreciated and effective avenues for promoting female leadership. That is, society membership is often self-selective, and board positions are elected (with a high turnover compared to institutions)—these characteristics, among others, may thus create an environment conducive to gender equality. We therefore investigate this potential using an information-theoretic approach to quantify gender equality (male:female ratios) in zoology society boards around the world. We compare alternative models to analyze how society characteristics might predict or correlate with the …
Behavior change types with Pokémon GO
2017
Digital games1 are one of the most popular entertainment media in the world. Teir allure and widespread popularity makes them an interesting and highly potential platform for behavior change atempts. In this paper, we investigate what types of behavior changes Pokémon GO has promoted or induced among its players. Te study is based on an online survey sample of 262 Pokémon GO players, collected using the critical incident technique and analyzed using qualitative methods. Te analysis shows that the behavior changes induced by Pokémon GO are not just restricted to increased physical activity or social behavior but are actually much more multifaceted: players were more social, found their routi…
