An Empirical Study on the Ecological Economy of the Huai River in China
Authors: Zhang Chunmei , Wang Chengxiang , Mao Guangxiong , Wang Min , Hsu Wei-Ling
Published: August 2020

The Huai River is an important flood control and discharge river in the middle and east of China, and the development of ecological economy with regional advantages is significant for the protection and improvement of the resources and environment of the basin. On the basis of defining the connotation of an ecological economic system, this study constructed an index system, and it applied the methods of data envelopment analysis (DEA) and exploratory spatial data analysis (ESDA) to study the ecological economy of the Huai River. This study concluded that (1) the efficiency in most areas was efficient, but inefficient in a few areas; (2) the causes of inefficiency were unreasonable production scale and unqualified production technology, which led to redundant input of resources, insufficient output of days with good air quality, and excessive output of particulate matter with less than or equal to 2.5 microns in diameter (PM2.5); and (3) the efficiency was different in different regions, so it was necessary to respectively formulate and implement strategies for protection and development of resources and environment. The research results can be used as an important reference for formulating ecological economic policies around the world.

Published: August 2020

While stream restorations are increasingly being adopted to mitigate sediment and nutrient inputs and to meet water quality regulatory targets, less information is available on the drivers behind the design, implementation, effectiveness, and cost of restorations. We address these issues for a $4.2 million stream restoration for legacy sediments implemented for a rural Piedmont stream in Maryland, USA. A total of 1668 m of stream was restored in three phases, which included the partial removal of legacy sediments, the grading of streambanks, floodplain creation, channel reshaping with meanders and pool-riffle forms, the raising of the stream bed, and the planting of riparian vegetation. The sediment, nitrogen, and phosphorus concentrations and fluxes were monitored before- and during the restoration phases. The sites selected for restoration had legacy sediments vulnerable to erosion and were on state-owned land. The restoration design was based on the need to maintain mature riparian trees and preserve existing sensitive wetland habitats. Water quality monitoring indicated that the sediment and nutrient fluxes increased during the restoration phase and were attributed to disturbance associated with construction activities and increased runoff. We also recommend that soil health needs to be included as an integral component to enhance the effectiveness and resilience of stream restorations.
Nuisance Algae in Ballast Water Facing International Conventions. Insights from DNA Metabarcoding in Ships Arriving in Bay of Biscay
Authors: Ardura Alba , Borrell Yaisel , Fernández Sara , González Arenales Mónica , Martínez José , Garcia-Vazquez Eva
Published: August 2020

Ballast water is one of the main vectors of transport of nuisance species among marine ports. Neither treatment nor interchange completely reduces the risk of ballast water containing DNA from harmful species, being a signal of potential threat. However, although there are some efficient treatments, they are not available on all ships and there might be some technological/economical constrains for their active and routine usage. Understanding what routes lead to a higher risk of contamination is important for designing targeted surveillance. We analysed ballast water from seven ships arriving in Gijon port (south Bay of Biscay, Spain). DNA metabarcoding was employed for identification of exotic species and harmful algae. One ship carried DNA of 20 risk species in the ballast water. Three ships contained DNA of only one risk species, and three ships had none. Seventy two algae species were found, 22.2% are exotic to the Bay of Biscay and 11.1% are catalogued as harmful. The results demonstrated the importance of continuous surveillance of ballast water.
Habitats and Diversity of Subterranean Macroscopic Freshwater Invertebrates: Main Gaps and Future Trends
Authors: Dumnicka Elzbieta , Pipan Tanja , Culver David
Published: August 2020

Caves are the best studied aquatic subterranean habitat, but there is a wide variety of these habitats, ranging in depth below the surface and size of the spaces (pore or habitat size). Both factors are important in setting limits to species composition and richness. In addition to caves, among the most important shallow aquatic subterranean habitats are the hyporheal (underflow of rivers and streams), the hypotelminorheal (very superficial drainages with water exiting in seeps), epikarst, and calcrete aquifers. Although it is little studied, both body size and species composition in the different habitats is different. Because of high levels of endemism and difficulty in access, no subterranean habitats are well sampled, even caves. However, there are enough data for robust generalizations about some geographic patterns. Individual hotspot caves are concentrated in the Dinaric region of southern Europe, and overall, tropical regions have fewer obligate aquatic cave dwellers (stygobionts). In all subterranean aquatic habitats, regional diversity is much higher than local diversity, but local diversity (especially single cave diversity) may be a useful predictor of regional species richness. In Europe there is a ridge of high aquatic subterranean species richness basically extending east from the French–Spanish border. Its cause may be either high productivity or that long-term temperature oscillations are at a minimum. With increased collecting and analysis, global and continental trends should become clearer.
The Design of Pricing Policies for the Management of Water Resources in Agriculture Under Adverse Selection
Authors: Viaggi Davide , Galioto Francesco , Lika Alban
Published: August 2020

Water pricing policy for irrigated agriculture is considered as a key issue in the Water Framework Directive (WFD) implementation. The main obstacle is that a large part of the water used in agriculture is unmetered. The objective of this study is to assess the Water Authorities (WA)’s choices between different options of incentive pricing policies (IPP) and to evaluate their economic performance compared with flat rate (FR) solutions. The applied method relies on a principal-agent model under adverse selection, in which WAs are less informed than farmers about the water use costs and profits. In this respect, the paper provides a theoretical interpretation of how different information conditions, profit and cost structures contribute to affecting WAs’ pricing strategies and their ability to deal with some of the WFD principles. The study shows that, in the absence of water metering, WAs can still set up incentive pricing strategies by formulating menus of contracts that are more efficient than flat rate payments. Also, we show that, at least for cases in which there is only a small differentiation in water costs among farmers or no transaction costs, the first-best solution (the solution that yields the highest return from the use of the resource) can also be optimal under asymmetric information. The main policy recommendation is that, in the absence of water metering, a wider set of incentive pricing options should be considered, the performance of which, however, should be evaluated based on the specificities of each irrigated region.
Source Apportionment Assessment of Marine Sediment Contamination in a Post-Industrial Area (Bagnoli, Naples)
Authors: Giglioli Sara , Colombo Loris , Contestabile Pasquale , Musco Luigi , Armiento Giovanna , Somma Renato , Vicinanza Diego , Azzellino Arianna
Published: August 2020

The area of Bagnoli (Gulf of Naples, central Tyrrhenian Sea) has been heavily exposed to pollution for over a century due to the presence of industrial sites along its coastline. The aim of this study is to analyze contaminant concentrations (i.e., heavy metals and hydrocarbons) in seabed sediments through a statistical multivariate approach. Multivariate methods permit us to describe the pollution dynamics affecting the area and distinguish between anthropogenic and natural pollution sources. Additionally, the association between contamination patterns and the wave climate characteristics of the gulf (i.e., wave period, direction, height, power, and energy) is investigated. The study confirms that the main contamination source in the Bagnoli bay is anthropogenic activities (i.e., former steel plant and sewage discharges) for the majority of investigated pollutants. It also provides evidence, however, for the potential co-existence of multiple anthropogenic and geogenic sources of arsenic and other metals that may be originating also from the water-rock interaction and submarine volcanic emissions in the Phlegraean area.

El sistema de las necesidades y la sociedad civil
Authors: De Zan Julio
Published: August 2020

El modelo jurídico de la constitución de la sociedad y del estado mediante la ficción de un contrato social es reemplazado por Hegel mediante dos puntos de vista diferentes y complementarios: a) el modelo económico del sistema de las necesidades, que se rige por su propia ley inmanente a la cosa misma de esta esfera, y llega a producir en la sociedad civil una integración real más sólida y a la vez más dinámica que la de las comunidades tradicionales premodernas. b) la integración política sustantiva del espíritu objetivo que hace posible la regulación de los desequilibrios e injusticia de la sociedad civil por el Estado mediante una política moderadamente intervencionista. Más allá del sistema de la competitividad, la sociedad civil es también el continente y la trama de la solidaridad y la beneficencia, la cooperatividad corporativa de artes y oficios, las instituciones públicas no estatales de contralor y de administración de justicia, las actividades públicas del saber y la cultura, la formación de la opinión pública y la actividad de la clase universal que, más allá de la clase política, debe ser independiente del Estado y tiene como fin lo universal en cuanto tal, la formación de las otras clases, especialmente de la clase política y de los funcionarios, el juicio crítico y la contribución a la organización constitucional del Estado.
Posiciones infundadas en la polémica sobre Mundos Posibles
Authors: Toranzo Calderón Joaquín Santiago
Published: August 2020

En la polémica entre actualistas y realistas modales, se ha recurrido a las nociones de necesidad y posibilidad lógicas, para responder a la pregunta por la existencia de los mundos posibles, defendiendo a partir de ellas sus contrapartidas metafísicas. Sin embargo, ¿pueden definirse unas puramente en términos de las otras? ¿O acaso es necesario algo más? En este trabajo se muestra que la relación entre estas nociones asume compromisos metafísicos previos recayendo en una justificación circular, por lo que no puede ser una opción viable para responder a tal pregunta.
Indexicalidad y "mundo actual"
Authors: Cuenca Alba E.
Published: August 2020

Este trabajo se propone revisar la postura que sostiene que “el mundo actual” es un indéxico que funciona como lo hacen “yo”, “ahora”, “aquí”, etc. Dicha postura es la sostenida por David Lewis (1970), para defender su realismo modal, es decir, la teoría de que existen mundos posibles que tienen el mismo estatus ontológico que el mundo en el que habitamos. A pesar de la importancia y novedad que tuvo el análisis indexical de mundo actual, este no está exento de objeciones que dificultan sostenerlo. A lo largo de este trabajo presentaremos distintas objeciones al análisis indexical y argumentaremos que un análisis descriptivo de “mundo actual” es el adecuado.

Published: August 2020

En este trabajo se reporta las derivaciones de la valoración de la satisfacción del usuario acerca del servicio de transporte de autobuses para la zona de la ciudad de Toluca, México. Los factores identificados en una primera fase fueron tres cuantitativos: tiempo de espera (te), tiempo a bordo del autobús (tv), y costo del viaje (cv): tarifa; y 15 factores cualitativos enmarcados en tres dimensiones del servicio: forma de manejar (foma), trato que recibe el usuario (trato) y estado físico del autobús (edofís). Posteriormente se diseñó y aplicó una encuesta de satisfacción para obtener las percepciones  de los usuarios acerca de los niveles de calidad de los 18 factores previamente identificados, esas percepciones se lograron atrapar mediante escalas tipo Likert con cinco niveles previamente seleccionadas y afinadas mediante un grupo focal. A partir del análisis realizado se infiere que para aumentar la satisfacción del usuario es necesario llevar a cabo implementaciones dirigidos a factores cualitativos más que en los aspectos operativos. Lo que permitirá a la empresa de transporte público redefinir y administrar sus directrices de calidad de servicio con la finalidad de mejorar su imagen, repercutiendo en una mejoría del usuario durante el viaje en transporte público.

Espacios funerarios y migración: contornos difusos y territorialidad en las principales provincias de acogida en los siglos XIX y XX
Authors: Castiglione Celeste
Published: August 2020

En las entrevistas realizadas a lo largo de los años hay un tema que se desprende como uno de los elementos que componen la historia y la trayectoria migratoria de manera privilegiada en las representaciones individuales y colectivas: la muerte. Ésta se configura como un marco referencial que responde a persistencias y transformaciones conceptuales que la sociedad y cada grupo en ella considera como propio o representativo de su identidad. De forma tal que los rituales y los modos de evocar la muerte manifiestan parte del capital económico, social, cultural y simbólico que los migrantes poseen de acuerdo a su lugar de origen. Asimismo, el morir fuera del marco de referencia los obliga a articular formas de complementación y cooperación, así como sortear conflictos para conseguir espacios en donde enterrar a sus muertos de acuerdo a su ritualidad y performatividad identitaria. El presente trabajo es el resultado de un recorrido por 165 cementerios de las principales provincias de acogida de la migración en Argentina que arribó desde mediados del siglo XIX y principios del XX y las formas que han elegido para conmemorar a sus difuntos.
La red vial como estructura posibilitante del desarrollo en el área metropolitana de Córdoba, Argentina
Authors: Boccolini Sara
Published: August 2020

La red vial de una región urbana funciona como canal de flujos (de personas y bienes), conduciéndolos desde y hacia distintos puntos en el territorio, pero también forzando este tráfico en ciertas regiones en desmedro de otras. Debido a esto, su análisis es indispensable para comprender el escenario actual de una región metropolitana y delinear tendencias de desarrollo a mediano plazo. Sin embargo, debido a su extensión y complejidad, su estudio suele priorizar valoraciones cualitativas. En este trabajo se analizó la red vial del área metropolitana de Córdoba (Argentina) dentro del marco instrumental y conceptual de la Sintaxis Espacial, que permite valorar cuantitativamente los niveles de conectividad e integración global de los elementos que componen la red en función de su articulación dentro del sistema vial y sus características topológicas. Además, se analizó la Sintaxis Espacial tanto en función de su potencial como herramienta analítica como de las limitaciones en su capacidad explicativa. Para superar éstas últimas, los resultados se analizaron en combinación con patrones de distribución de la población y de equipamientos y servicios urbanos a escala metropolitana, y se determinaron tendencias de desarrollo en cuanto a reestructuración del área urbanizada y polarización socioeconómica.

Construyendo territorialidades: estrategias residenciales y prácticas cotidianas de mujeres bolivianas en Comodoro Rivadavia
Authors: González Myriam Susana
Published: August 2020

La territorialidad ocupa un lugar creciente en el análisis de las migraciones internacionales, tanto a nivel de las relaciones entre los espacios materiales, sociales, culturales y políticos, como a nivel de las prácticas. Partimos de la idea que los territorios urbanos están marcados por relaciones de poder, de allí que la capacidad de construir lugares sea un producto de las estrategias de los actores sociales que los habitan y presenta diferencias de género, clase y etnia. El foco del trabajo está puesto en las mujeres bolivianas residentes en Comodoro Rivadavia, en sus estrategias y prácticas y en las nuevas territorialidades que construyen. Se busca recuperar las relaciones e interacciones de las migrantes, los sentidos y significados, las movilidades, accesibilidades y reclusiones que se producen en la vida cotidiana, en el interior de los barrios de residencia y fuera de ellos. El abordaje se basa en una estrategia de investigación cualitativa, a partir de observaciones en el terreno, entrevistas a informantes clave y, en particular, entrevistas en profundidad.

Published: August 2020

La interoperabilidad de un sistema de información unificado desafía el manejo de datos y su comunicación en un mismo formato. El ferrocarril argentino transita un momento de modernización, por lo cual es esencial disponer de un conjunto de datos precisos sobre su red. La variedad y dispersión de fuentes amerita el desarrollo de un criterio objetivo sobre la recolección de esa información. Por ello, el uso de los SIG se presenta como una herramienta adecuada para acompañar tal proceso, brindando grandes ventajas a la planificación. Este artículo propone una metodología para el manejo de la información y concluye sobre la pertinencia de homologar y establecer un criterio unificador de los datos al diseñar un SIG. El trabajo se compone de dos secciones: una de ellas trata sobre las fuentes sustanciales para un trabajo con SIG sobre ferrocarriles y la otra presenta el modelo de acción propuesto por los autores.

Constructing Relationship between Software Metrics and Code Reusability in Object Oriented Design
Authors: M. Manoj H. , N. Nandakumar A.
Published: August 2020

The role of design pattern in the form of software metric and internal code architecture for object-oriented design plays a critical role in software en-gineering in terms of production cost efficiency. This paper discusses about code reusability that is a frequently exercised cost saving methodology in IT produc-tion. After reviewing existing literatures towards study on software metrics, we found that very few studies are witnessed to incline towards code reusability. Hence, we developed a simple analytical model that establishes relationship between the design components of standard software metric and code reusability using case studies of three software projects (Customer Relationship Management project, Supply Chain Management project, and Enterprise Relationship Management project). We also testify our proposal using stochastic based Markov model to find that proposed system can extract significant information of maximized values of code reusability with increasing level of uncertainties of software project methodologies.
Image Inpaint Using Patch Sparsity
Authors: Suryawanshi Shital D. , Baviskar P. V.
Published: August 2020

The process of removing the specific object or area or repairing the damaged area in an image is known as image inpainting. This algorithm [5] is proposed for removing objects from digital image. The challenge is to fill in the hole that is left behind in a visually plausible way. We first note that patch sparsity based synthesis contains the essential process required to replicate both texture and structure [8]; the success of structure propagation however is highly dependent on the order in which the filling proceeds. We propose a best algorithm in which the confidence in the synthesized pixel values is propagated in a manner similar to the propagation of information in inpainting.The actual color values are computed using patch sparsity based synthesis. In this paper the simultaneous propagation of texture and structure information [2] is achieved by a single, efficient algorithm. For best results selected image should have sufficient background information

Handling such data is a challenge for knowledge discovery particularly in colocation mining.One straightforward method is to find the Probabilistic Prevalent colocations (PPCs). This method tries to find allcolocations that are to be generated from a random world. For this we first apply an approximation error to find allthe PPCs which reduce the computations. Next find all the possible worlds and split them into two different worldsand compute the prevalence probability. These worlds are used to compare with a minimum probability threshold todecide whether it is Probabilistic Prevalent colocation (PPCs) or not. The experimental results on the selected dataset show the significant improvement in computational time in comparison to some of the existing methods used incolocation mining.

With the increased growth of career opportunities in STEM fields, educators and policymakers have sought to better understand the nature and development of students’ motivation to pursue science academic and career pathways successfully. However, our understanding of motivational constructs such as self-efficacy has mostly been based on studies of predominantly White samples, neglecting the perspectives and experiences of students from historically marginalized groups underrepresented in STEM academic and career pathways. In the present study, we examined science motivation in six high school students of color who participated in a brief, near peer mentoring program with undergraduate mentors of color. Deductive and inductive coding of semi-structured interviews with mentees and mentors revealed that science self-efficacy not only has a salient future-oriented component, but also centers around the importance of forming and maintaining interpersonal connections with others through proxy agency and help-seeking behaviors. These data point to the utility of a sociocultural perspective in expanding our understanding of self-efficacy—and motivational processes more generally—in a way that is more inclusive of the experiences of racial and ethnic minority youth.

This paper aims to examine and understand the form of factionalisation and Internal Conflict of Partai Persatuan Pembangunan (PPP) in people's perception of its existence as a political party. The method uses a qualitative approach with data and information obtained through interviews and library research methods. The data and arguments built in this paper use qualitative studies, namely by gathering various scientific references and from primary and secondary sources through searching for writings related to books, journals, papers, newspapers, magazines and direct interview results with informants related to problem in this study. The results showed that the internal PPP conflict was caused by differences in the views of political elite in determining the coalition carrying the presidential candidates. This happened in the PPP in 2014 when there were differences in the nominations between Suryadharma Ali and Romahurmuziy. The conflict then led to the dualism of the leadership of the Suryadharma Ali and Romahurmuziy camps. Another factor driving conflict is the different backgrounds of cadres in the political parties. Therefore, conflict management absolutely needs a political party.

A poluição do ar é influenciada por fatores naturais e antropogênicos. Quatro pontos de monitoramento (veicular, comercial, residencial e background urbano (BGU))da poluição do ar em São Paulo foram avaliados durante 16 anos, revelando diferenças significativas devidoao uso do solo em todas as escalas temporais. Na escala diurna, as concentrações de poluentes primários são duas vezes mais altas nos pontos veicular e residencial do que no ponto BGU, onde a concentração de ozonio (O3) é 50% mais alta. Na escala sazonal, as concentrações de monóxido de carbono(CO) variaram em 80% devido ao uso do solo, e 55% pela sazonalidade.As variações sazonais ede uso do solo exercem impactos similares nas concentrações de O3 e monóxido de nitrogênio (NO). Para o material particulado grosso (MP10) e o dióxido de nitrogênio(NO2), as variações sazonais são mais intensas do que as por uso do solo. Na série temporal de 16 anos, o ponto BGU apresentou correlações mais fortes e significativas entre a média mensal de ondas longas (ROL) e o O3 (0,48) e o MP10 (0,37), comparadas ao ponto veicular (0,33 e 0,22, respectivamente). Estes resultados confirmam que o uso do solo urbano tem um papel significativo na concentração de poluentes em todas as escalas de análise, embora a sua influência se torne menos pronunciada em escalas maiores, conforme a qualidade do ar transita de um sistema antropogênico para um sistema natural. Isto poderá auxiliar decisões sobre políticas públicas em megacidades envolvendo a modificação do uso do solo.

With the current global urge and mandates for gender equality, the African continent is re-awakening interest on gender issues and gender mainstreaming in public policy and planning. This paper addresses issues and prospects in embracing Gender Equality and Women Empowerment (GEWE) principles in a democratizing state such as Nigeria. Basic questions raised include – what are the ideals of GEWE? What relevance does the GEWE Agenda have for a democratising state? What different legislations, policies, and programmes are strategic to this process? What roles have been played by Civil Society Organizations in instituting a GEWE agenda in a nation state such as Nigeria? What are the gains of the gender equality agenda for the country’s overall development? What problems still face the process of achieving gender equality and gender justice in Nigeria? These discussions espouse the importance of the GEWE Agenda and the need to engender social development and political transformations in the emerging democratic Nigeria.
Gender and Women's Political Leadership in Nigeria

Published: August 2020

Political leadership in Nigeria are stratified on the basis of gender distinction, thereby calling to question the assertion of gender neutrality in the political arena. Looking beyond the usual sex variable in a survey, this paper explores the consequences of gender and women’s political leadership in Nigeria using case studies approach to appraise the life histories of two groups of women. It takes gender as a category of analysis, recognizing the contributions feminist theorists have made. The cases observed in this study confirm the capability of Nigerian women to hold political leadership roles and to engage in decision-making activities that can affect the nation’s development. Though, more emphasis should be placed on power politics, without necessarily deemphasising alternative options such as affirmative action, it should, however, be pursued within the framework of competitive politics so that the legitimacy, effectiveness and autonomy of women in decision-making will not be compromised.

The family institution, which is the basic foundation of every society, is being threatened by high rate of divorce globally. The literature and popular media are replete with statistics about the rise in the rate of divorce and the decreasing stability of the nuclear family. It is believed that this situation often results into an unstable society and even destroys its form and moral standards. Consequently the adolescents who are raised in such broken homes are more likely to drop out of school, to use drug, to have teen births, to have illegitimate children and to be poorer than their counterparts whose natal home is intact. It is therefore germane to ask the following questions: what are the factors responsible for the high incidence of divorce, and what are the effects of divorce on the society? The main trust of this paper is to x-ray the factors responsible for high incidence of divorce in the context of feminist theory, the individualism dual income paradigm and to know the effect of divorce on the children, the couples involved and the society at large. In line with these objectives, the paper relies on secondary material and primary data obtained through questionnaire in order to assess the phenomenon of divorce in Ilorin Emirate. The study reveals that the main factors associated with divorce in the Emirate are financial problems, barrenness and irresponsibility. The paper concludes with some suggestions on the ways to minimize or reduce the divorce rate in Ilorin in particular and human societies in general.
