Sustainable Entrepreneurial Orientation: A Business Strategic Approach for Sustainable Development
2017
This paper proposes sustainable entrepreneurial orientation (SEO) as a multidimensional construct that offers researchers the possibility of empirically testing their theoretical proposals in the sustainable entrepreneurship field. The authors propose an integration of different theories. In accordance with the dynamic capabilities view, SEO is approached under an organizational paradigm of strategic orientations delimited by competitive culture and multiple orientation perspectives. Furthermore, SEO's nature is conceived at a firm-based entrepreneurship level and is based on an integrated triple bottom line sustainability. This approach is conceptualized using a categorization scheme and d…
Entrepreneurs’ interpersonal communication competence in networking
2020
Modern international business calls for competencies that enable entrepreneurs to be creative, innovative, effective and capable of networking. Competencies in forming and developing networks are particularly valuable for organizations and companies in countries with small economies, such as Finland, that are dependent on export and profitable international business. The aim of this research is to build understanding of what kind of interpersonal communication competence (ICC) entrepreneurs need in networking.
 Since the classic work of Granovetter (1982) and others (see e.g. Håkansson, 1982; Håkansson & Snehota, 2000), network theory and network analysis have become popular when t…
Issues on Financing Sources of Environmental Fund In Romania
2017
Abstract Environmental taxation has been developing for decades and it started to gain its importance, especially with the European Union extending. The usage of taxes as a part of environmental policy has been known for some time in Romania and developments in this area continued year by year. The present paper explores the current system of environmental taxes in Romania. It highlights the importance of car pollution tax in financing Environmental Fund and the existence of many tax liabilities irrelevant as financial importance.
Energy reserves mobilization in the yellow eel as herbicide exposure effect.
2015
Abstract Thiobencarb and propanil are two of the most extensive used herbicides worldwide in rice cultivation. Especially scanty is the available information regarding the effect of herbicides on fish energy resources. In the present study, the effect of sublethal exposure to these herbicides on the energy reserves of juvenile eel Anguilla anguilla was compared. Eels were exposed to 72 h to the herbicide thiobencarb (0.22 mg L −1 ) or Propanil (0.63 mg L −1 ), and allowed to recover in clean water (144 h). Caloric content was determined in liver and skeletal muscle. Fish exposed to thiobencarb rapidly mobilized energy. Reserves from liver were depleted (21%) compared to control values (2.50…
Transfer of hexazinone and glyphosate through undisturbed soil columns in soils under Christmas tree cultivation.
2004
Abstract Field studies monitoring pesticide pollution in the Morvan region (France) have revealed surface water contamination by some herbicides. The purpose of this study was to investigate in greater detail the transport of two herbicides, used in Christmas tree production in the Morvan, under controlled laboratory conditions. Thus, the leaching of hexazinone (3-cyclohexyl-6-dimethyl-amino-1-methyl-1,3,5-triazine-2,4 (1H,3H) dione) and glyphosate ( N -(phosphono-methyl-glycine)) through structured soil columns was studied using one loamy sand and two sandy loams from sites currently under Christmas tree cultivation in the Morvan. The three soils were cultivated sandy brunisol [Sound refer…
Estimating the environmental and resource costs of leakage in water distribution systems: A shadow price approach.
2016
Water scarcity is one of the main problems faced by many regions in the XXIst century. In this context, the need to reduce leakages from water distribution systems has gained almost universal acceptance. The concept of sustainable economic level of leakage (SELL) has been proposed to internalize the environmental and resource costs within economic level of leakage calculations. However, because these costs are not set by the market, they have not often been calculated. In this paper, the directional-distance function was used to estimate the shadow price of leakages as a proxy of their environmental and resource costs. This is a pioneering approach to the economic valuation of leakage exter…
Groundwater sustainability: Developing a non-cooperative optimal management scenario in shared groundwater resources under water bankruptcy condition…
2021
Abstract Groundwater level drawdown changes the hydrological cycle and poses challenges such as land subsidence and reduction of the groundwater quality. In this study, a new approach using a simulation-optimization framework was developed for shared groundwater management under water bankruptcy conditions (where water demand is greater than the allowable discharge capacity of water resources). The novelty of this study lies in using bankruptcy rules and a game model to manage a bankrupted shared groundwater resource considering aquifer sustainability. Accordingly, groundwater flow in the aquifer was numerically simulated by a finite-differences model (MODFLOW). Then, the repeated performan…
Subsecond pore‐scale displacement processes and relaxation dynamics in multiphase flow
2014
With recent advances at X‐ray microcomputed tomography (μCT) synchrotron beam lines, it is now possible to study pore‐scale flow in porous rock under dynamic flow conditions. The collection of four‐dimensional data allows for the direct 3‐D visualization of fluid‐fluid displacement in porous rock as a function of time. However, even state‐of‐the‐art fast‐μCT scans require between one and a few seconds to complete and the much faster fluid movement occurring during that time interval is manifested as imaging artifacts in the reconstructed 3‐D volume. We present an approach to analyze the 2‐D radiograph data collected during fast‐μCT to study the pore‐scale displacement dynamics on the time s…
Islands of biogeodiversity in arid lands on a polygons map study: Detecting scale invariance patterns from natural resources maps.
2016
Many maps (geology, hydrology, soil, vegetation, etc.) are created to inventory natural resources. Each of these resources is mapped using a unique set of criteria, including scales and taxonomies. Past research indicates that comparing results of related maps (e.g., soil and geology maps) may aid in identifying mapping deficiencies. Therefore, this study was undertaken in Almeria Province, Spain to (i) compare the underlying map structures of soil and vegetation maps and (ii) investigate if a vegetation map can provide useful soil information that was not shown on a soil map. Soil and vegetation maps were imported into ArcGIS 10.1 for spatial analysis, and results then exported to Microsof…
Evaluation of Biogas Production and Usage Potential
2016
Abstract The aim of the research is the development of theoretical and methodical bases for determining the feasibility of plant raw materials growing for its further bioconversion into energy resources and technological materials to maximize profit from business activities. Monograph, statistics, modelling and abstract logical methods have been used during the research. Directions of biogas usage have been examined. Biogas yields from different crops have been analyzed. It has been determined that high methane yields can be provided from root crops, grain crops, and several green forage plants. So, forage beet and maize can provide more than 5,500 m3 of biogas per hectare. Attention is pai…
