Foreign Direct Investment in oil-abundant countries: The role of institutions

2019

The present work reassesses the impact of good governance and democracy on Foreign Direct Investment (FDI) in oil-abundant countries. To this end, we estimate the effect of host countries’ institutions on greenfield FDI, using a gravity equation for a dataset that covers 182 countries during 2003-2012. Our findings confirm that compliance to rule of law, lack of corruption, political stability and democracy could boost new FDI links through the extensive margin. Our results could not rule out the “oil curse”, meaning that oil producers attract fewer new greenfield projects than similar countries without oil. Unlike other studies, we show that the impact of institutions is not necessarily un…

Bronhiālās astmas ārstēšanai izmantojamo zāļu aprite A aptiekā 23 Krāslavā no 2012.gada līdz 2015. gadam

2015

Bronhiālā astma ir plaši izplatīta slimība gan visā pasaulē, gan arī Latvijā. Latvijā ar astmu aizvien vairāk slimo mazi bērni. Astma skar visu vecuma cilvēkus, bet visbiežāk tā sākas bērnībā. Tā tiek raksturota kā elpošanas sistēmas slimība ar hronisku, iekaisīgu raksturu. Astmas simptomi katram pacientam atšķiras, tāpēc nepieciešams katram pacientam izvēlēties atbilstošu stratēģiju, kas ļautu labi kontrolēt astmas simptomus. Šī darbā mērķis ir noskaidrot bronhiālās astmas ārstēšanā izmantojamo zāļu aprites tendences kopš 2012. gada līdz 2015. gadam A Aptiekā 23 Krāslavā, balstoties uz Global Initiative for Asthma (GINA) 2011.g. vadlīnījām. Var secināt, ka lielas atšķirības šo triju gadu l…

Effects of high intensity resistance aquatic training on body composition and walking speed in women with mild knee osteoarthritis : a 4-month RCT wi…

2017

Objective: To investigate the effects of 4-months intensive aquatic resistance training on body composition and walking speed in post-menopausal women with mild knee osteoarthritis (OA), immediately after intervention and after 12-months follow-up. Additionally, influence of leisure time physical activity (LTPA) will be investigated. Design: This randomised clinical trial assigned eighty-seven volunteer postmenopausal women into two study arms. The intervention group (n = 43) participated in 48 supervised intensive aquatic resistance training sessions over 4-months while the control group (n = 44) maintained normal physical activity. Eighty four participants continued into the 12-months' fo…

A comparison of two different formulations for Arc Routing Problems on Mixed graphs

2006

[EN] Arc routing problems on mixed graphs have been modelled in the literature either using just one variable per edge or associating to each edge two variables, each one representing its traversal in the corresponding direction. In this paper, and using the mixed general routing problem as an example, we compare theoretical and computationally both formulations as well as the lower bounds obtained from them using Linear Programming based methods. Extensive computational experiments, including some big and newly generated random instances, are presented.

New Heuristic Algorithms for the Windy Rural Postman Problem

2005

[EN] In this paper we deal with the windy rural postman problem. This problem generalizes several important arc routing problems and has interesting real-life applications. Here, we present several heuristics whose study has lead to the design of a scatter search algorithm for the windy rural postman problem. Extensive computational experiments over different sets of instances, with sizes up to 988 nodes and 3952 edges, are also presented. (c) 2004 Elsevier Ltd. All rights reserved.

A branch-and-cut algorithm for the Profitable Windy Rural Postman Problem

2016

[EN] In this paper we study the profitable windy rural postman problem. This is an arc routing problem with profits defined on a windy graph in which there is a profit associated with some of the edges of the graph, consisting of finding a route maximizing the difference between the total profit collected and the total cost. This problem generalizes the rural postman problem and other well-known arc routing problems and has real-life applications, mainly in snow removal operations. We propose here a formulation for the problem and study its associated polyhedron. Several families of facet-inducing inequalities are described and used in the design of a branch-and-cut procedure. The algorithm…

On the impact of safety requirements, energy prices and investment costs in street lighting refurbishment design

2018

Abstract Street lighting is an indispensable feature for the night landscape of cities. It is important for road safety, users visual comfort, crime prevention and to augment the perceived personal safety. Realize and maintain an adequate street lighting service is very expensive for municipalities with significant impact on their budgets. For this reason, special attention should be paid to the design of new street lighting systems and to the refurbishment of existing ones, since many of them are inadequate. In light of this it is very important to implement street lighting designs that fulfil lighting requirements avoiding energy waste and light pollution and, at the same time, result eco…

Cap Rate as the Interpretative Variable of the Urban Real Estate Capital Asset: A Comparison of Different Sub‐Market Definitions in Palermo, Italy

2017

Real estate capital is in constant competition with other capital assets due to its different and complementary economic functions such as direct use, productive investment, and speculative investment. These features and the resulting opportunities cannot be easily deduced from direct observation of the real estate markets, so some further insights need to be carried out in order to highlight the relationship between prices, rents and performances. This study aims at providing a multifaceted perspective of a specific urban real estate market to overcome the difficulties arising from opacities and informative asymmetries that hinder the decision of investors, by facilitating the comparison o…

Sphères privée et professionnelle chez les enseignants du premier degré : comment priorisent-ils ?

2019

Private and professional lives among primary teachers: how they prioritize? Being a teacher in primary school seems far from allowing the articulation of work and private life in such a comfortable manner as seen in collective beliefs. In order to deconstruct the belief considering teachers as privileged, this contribution proposes, based on empirical results (an online survey with 21,642 responses), to report, first, how primary teachers prioritize their private or professional lives. Second, this paper highlights the reasons which lead them to favour one of the two fields, notably when priority is given to private life at the expense of professional life. Referring to the issue of work-fa…
