Price Dynamics and Cointegration in the Major Markets of Aquaculture Species in the Philippines
This study explores the interdependencies of aquaculture markets in the Philippines by establishing the price cointegration between the wholesale and retail prices of three major species commonly farmed in the country, i.e., milkfish, tilapia, and shrimp. The co-movements of wholesale prices between and among key markets for each species are also investigated. Moreover, exogeneity in prices is
established using the Granger-causation model to determine the existence of price leaders among these markets. These information are crucial because they may provide a better understanding of the efficiency in price formation across production and consumption centers. Thus, aquaculture producers and traders may use these information as basis for more efficient farm management and marketing decisions. Appropriate policies for the development of markets for the three aquaculture species are also identified in this study. Such policies are expected to contribute towards more efficient pricing and distribution of benefits among market players and stakeholders. These benefits are expected to manifest through the system of grading standards for fish traded in local markets, and the choice of cost-effective technologies in grow-out and post-production practices.
Public entities driven robotic innovation in urban areas
Cities present new challenges and needs to satisfy and improve lifestyle for their citizens under the concept “Smart City”. In order to achieve this goal in a global manner, new technologies are required as the robotic one. But Public entities unknown the possibilities offered by this technology to get solutions to their needs. In this paper the development of the Innovative Public Procurement instruments is explained, specifically the process PDTI (Public end Users Driven Technological Innovation) as a driving force of robotic research and development and offering a list of robotic urban challenges proposed by European cities that have participated in such a process. In the next phases of the procedure, this fact will provide novel robotic solutions addressed to public demand that are an example to be followed by other Smart Cities.Peer ReviewedPostprint (author's final draft
Harnessing the Effect of Adoptively Transferred Tumor-Reactive T Cells on Endogenous (Host-Derived) Antitumor Immunity
Adoptive T cell transfer therapy, the ex vivo activation, expansion, and subsequent administration of tumor-reactive T cells, is already the most effective therapy against certain types of cancer. However, recent evidence in animal models and clinical trials suggests that host conditioning interventions tailored for some of the most aggressive and frequent epithelial cancers will be needed to maximize the benefit of this approach. Similarly, the subsets, stage of differentiation, and ex vivo expansion procedure of tumor-reactive T cells to be adoptively transferred influence their in vivo effectiveness and may need to be adapted for different types of cancer and host conditioning interventions. The effects of adoptively transferred tumor-reactive T cells on the mechanisms of endogenous (host-derived) antitumor immunity, and how to maximize their combined effects, are further discussed
Programa municipal de alumbrado público
El proyecto consiste en la realización del diseño de una instalación de alumbrado público con el fin de obtener ahorros energéticos, económicos y dañando lo menos posible al medio ambiente.
La instalación de alumbrado consiste en una obra nueva, dotando de alumbrado a diez calles que configuran la Urbanización LA FEMU. Esta zona se encuentra en la ciudad de Palma y se ha diseñado la instalación
siguiendo las normativas del Ayuntamiento de dicha ciudad.
Se ha realizado un estudio luminotécnico exhaustivo para determinar la cantidad exacta de luminarias a instalar y evitar así el derroche energétio y la cantidad excesiva de material. Se ha considerado el tema de la
contaminación lumínica en la elección de la luminaria a instalar.
También se ha realizado un estudio comparativo entre los diferentes sistemas de regulación de flujo del alumbrado para así determinar cuál es el sistema más conveniente para obtener ahorros energéticos.
En el estudio se ha detallado el proceso de reciclaje y tratamiento de los residuos de luminarias y soportes.
Por último, se realiza un estudio económico y de amortización del diseño de la instalación concluyendo que la inversión se recuperará en 2 años
Argumentación y educación: apuntes para un debate
This is an Author's Original Manuscript of an article published by Taylor & Francis in Infancia y Aprendizaje on 02/01/2016 available online at http://www.tandfonline.com/10.1080/02103702.2015.1111607The objective of the present article is twofold. On the one hand, it aims to analyse the relationship between argumentation and education with a special emphasis on the difficulties that occur when defining and assessing argumentative skills. These difficulties are related to the thinking patterns underlying the argumentation models and, at the same time, are reflected in the educational models used to train and to assess students’ argumentative skills. On the other hand, this article presents and discusses common and distinctive aspects of the papers selected for this monographEl artículo que se presenta tiene un doble objetivo. Por un lado, pretende analizar cuáles son las relaciones entre argumentación y educación, poniendo énfasis en las dificultades para definir en qué consisten las competencias argumentativas y en los debates que esta indefinición ocasiona. Estas dificultades se relacionan con los modelos normativos de pensamiento que subyacen más o menos explícitamente a los modelos de argumentación y, al mismo tiempo, se reflejan en los modelos educativos que quieren formar a los
estudiantes en las competencias argumentativas o que analizan las habilidades
de estos estudiantes. Por otro lado, en este artículo se presentan y comentan los aspectos comunes y diferenciadores de los artículos seleccionados en la convocatoria ‘Argumentación y Educación’ y que constituyen este número de la revistaWe would like to express our gratitude to the general editors who helped us in all of the decision making processes and to Anna Sala, for her technical help.

Technical Efficiency of Resource-Conserving Technologies in Rice -Wheat Systems: The Case of Bihar and Eastern Uttar Pradesh in India
This study has evaluated the technical efficiency of farmers engaged in rice-wheat cropping systems in North-eastern India, who are using Resource-Conserving Technologies (RCTs) such as Zero Tillage (ZT) and Direct Seeded Rice (DSR). These technology promotions are being carried out under the intervention of the Cereal Systems Initiative for South Asia (CSISA) project, primarily funded by the Bill and Melinda Gates Foundation. The resource-conserving technologies are being promoted as part of conservation agriculture supported by the project. The data used in this study have been derived from the socioeconomic surveys conducted in Eastern Uttar-Pradesh and Bihar in North-eastern India during the kharif season of 2009 and rabi season of 2010. A stochastic frontier analysis was carried out to investigate and compare the determinants of technical efficiency among the farmers receiving intervention and those who are not. The study has revealed that farmers receiving CSISA intervention have realized higher levels of technical efficiency. Additionally, farmers who are receiving subsidies and farmers who are planting more diversified crops have higher levels of technical efficiency.Conservation agriculture, Direct seeded rice, India, Resource-conserving technology, Technical efficiency, Stochastic frontier, Zero tillage, Agricultural and Food Policy, O30, Q18, O22,
Innovation and International High Skilled Migration
The international mobility of highly skilled employees in the last few decades has become an essential part of an economy. Simultaneously innovation and its' components have a large effect on the migration of skilled people. The goal of this paper is finding out if a greater degree of innovation in a country has a positive impact on the arrival of highly skilled immigrants. In order to achieve the aforementioned goal and following existing literature on the subject, an analysis on an international level was made regarding the effect of relevant innovation factors (number of patents; research and development funding (as % of GDP) and number of articles in scientific and technical journals) on immigration of highly skilled employees. The results of a regression analysis confirmed a significant relation between the number of patents, articles in scientific and technical journals and number of highly skilled immigrants (HQI). This means that countries with a relatively larger amount of the innovation factors have a great incentive that attracts talented people on an international scale, although in order to achieve this there is the need to promote and maintain a favourable institutional, economic and technological environment
