Author-level metrics: h-index and beyond
Author-level metrics are usually employed for academic promotion and research funding. The h-index is a way of measuring scientists’ productivity and impact on their field, determined by the number of publications and the number of times those publications have been cited. However, the h-index calculation does not capture the influence of factors such as research topics, article types, highly cited items, self-citations, number and position of authors, and academic career length. Nonetheless, variants of h-index that address some of these limitations correlate widely with their original metric, are not available in bibliographic databases and, overall, add little for measuring research productivity
Fibromyalgia Detection Based on EEG Connectivity Patterns
Objective: The identification of a complementary test to confirm the diagnosis of FM. The diagnosis of fibromyalgia (FM) is based on clinical features, but there is still no consensus, so patients and clinicians might benefit from such a test. Recent findings showed that pain lies in neuronal bases (pain matrices) and, in the long term, chronic pain modifies the activity and dynamics of brain structures. Our hypothesis is that patients with FM present lower levels of brain activity and therefore less connectivity than controls. Methods: We registered the resting state EEG of 23 patients with FM and compared them with 23 control subjects’ resting state recordings from the PhysioBank database. We measured frequency, amplitude, and functional connectivity, and conducted source localization (sLORETA). ROC analysis was performed on the resulting data. Results: We found significant differences in brain bioelectrical activity at rest in all analyzed bands between patients and controls, except for Delta. Subsequent source analysis provided connectivity values that depicted a distinct profile, with high discriminative capacity (between 91.3–100%) between the two groups. Conclusions: Patients with FM show a distinct neurophysiological pattern that fits with the clinical features of the disease
Cultural variations and design guidelines to attune health programs from Spain to the Netherlands: Attuning the TAS program to Dutch classrooms
This master thesis report is the result of a six-month-long graduation project for the Design for Interaction master at TU Delft. The report describes the development of the design guidelines to attune the TAS program to the Netherlands.The main goals that guided the project were three: identify which aspects of a healthy habit program (TAS program) can be adapted to the Netherlands; understand how to design for it by creating a set of design guidelines; and how to apply the guidelines to attune the program to the Netherlands.. Healthy habit programs targeted to teenagers are crucial since it is the period in which bodies develop and finish forming. The early understanding of healthy habits is key to helping teenagers to acquire lasting healthy behaviors and classrooms provide a great context that supports the knowledge building experience. The TAS program was evaluated in 103 Spanish classrooms, in different autonomous regions, and proved to increase healthy behaviors among teenagers, such as improving nutritional habits (increase of fruit and vegetable intake and decrease of fried food) or increasing physical activity. Therefore, the opportunity to adapt a successful healthy habit program to another European country was identified.The research phase of the project consisted mainly of sensitizing activities and literature research to get to know the context and domain of the project; and interviews with Dutch and Spanish parents and teenagers to understand the reality and daily life habits by comparison.The opportunity to design a set of guidelines based on the research outcomes was identified, a set of 10 guidelines grouped in four groups: medium, content, communication and engagement. The guidelines were applied to one of the workshops of the TAS program with the aim of evaluating the effectiveness of the guidelines and the workshop itself.The concept was evaluated with Spanish and Dutch secondary teachers and Dutch experts in the field of health programs in order to assess the validity of the concept and identify to what extent the implemented changes were culture specific.The project was approached from a cultural framework, in which socio-cultural dimensions served as a way to find a direction for the project but also as a tool to compare and identify cultural variables between Spain and the Netherlands.Design for Interactio

Technical Approach to Local Therapy in Ischemic Stroke
Local therapy is an increasingly achievable alternative for neurological diseases such as stroke. For its use to be a reality, it is still necessary to develop techniques that facilitate its administration and maximize its effect. In this short communication, we present a technique of intracerebral therapy administration. This procedure requires the use a navigation-guided stereotactic surgical technique to inject the treatment into the therapeutic target, even in areas that are difficult to access or extremely large. Such a method is not only fast and feasible, but it can be a standardized technique for multicentre clinical trials
Fisheries management measures in an MPA: socioeconomic impact assessment and governance issues in the case of the German small scale gillnet fisheries around the island of Fehmarn in the Baltic Sea
No abstracts are to be cited without prior reference to the author. To study whether the high level (Europe wide) point of view on fisheries policy objectives can be useful to shed light not only on the objectives discussion but also on the problem of micro-management a further step is taken by performing consultations with several actors around the German fisheries. Ecological, economic and social objectives developed inside the project SOCIOEC (Socioeconomic effects of the future CFP) are presented to fishermen, fishermen representatives, manager and environmental representatives in an attempt to fine tune them and make them suitable to serve as benchmarks for an impact analysis of current and future management measures

The psychosocial adaptation to the disease and quality of life of family Caregivers for people with dementia in the coexistence process: a proposal for social health intervention from psychosocial adaptation and quality of life
Con motivo de la recepción del primer premio Tomás Belzunegui 2017, la autora ofrece un resumen de su tesis doctoral, que aborda la adaptación psicosocial y calidad de vida de
las personas cuidadoras de familiares con demencia en el proceso de convivencia,
analizando esta realidad desde una perspectiva convivencial y la afectación que
padecen en una relación de cuidado a largo plazo. Para ello se utiliza una metodología
basada en la integración del análisis cuantitativo y el análisis cualitativo
(mixed-methods) con el objetivo de obtener los datos más precisos para la comprensión
de esta situación convivencial.
A través del análisis de estos resultados, se propone una propuesta de intervención
socioeducativa para abordar la cuestión planteada desde una perspectiva integral de
acción que permita mejorar la adaptación psicosocial y calidad de vida de la unidad
de convivencia que conforman las personas cuidadoras de familiares con demencia y
las propias personas enfermas.On the occasion of receiving the first Tomás Belzunegui 2017 award, the author offers a summary of her doctoral thesis, which addresses the psychosocial adaptation and quality of life of the
caregivers of family members with dementia in the process of coexistence, analyzing
this reality from a coexistence perspective and the affectation that they suffer in a
relationship of long-term care. For this, a methodology based on the integration of
quantitative analysis and qualitative analysis (mixed-methods) is used in order to obtain the most accurate data for the understanding this coexistence situation.
Through the analysis of these results, a socio-educational intervention proposal is
proposed to approach the question raised from an integral perspective of action that
allows to improve the psychosocial adaptation and quality of life of the coexistence
unit that make up the caregivers and people with dementia
Urban and regional heat island adaptation measures in the Netherlands
The urban planner´s role should be adapted to the current globalised and overspecialised economic and environmental context, envisioning a balance at the regional scale, apprehending not only new technologies, but also new mapping principles, that allow obtaining multidisciplinary integral overviews since the preliminary stages of the design process. The urban heat Island (UHI) is one of the main phenomena affecting the urban climate. In the Netherlands, during the heat wave of 2006, more than 1,000 extra deaths were registered. UHI-related parameters are an example of new elements that should be taken into consideration since the early phases of the design process.
Problem statement
Thus, the development of urban design guidelines to reduce the heat islands in Dutch cities and regions requires first an overall reflection on the heat island phenomenom (relevance of the large scale assessment, existing tools, instruments) and proposal of integrative and catalysing mapping strategies and then a specific assessment of the phenomenom at the selected locations in The Netherlands (testing those principles).
Main research question
Could the use of satellite imagery help analyse the UHI in the Netherlands and contribute to suggest catalysing mitigation acions actions implementable in the existing urban context of the cities, regions and provinces assessed?
Method
The development of urban design principles that aim at reaching a physical balance at the regional scale is critical to ensure a reduction of the UHI effect. Landsat and Modis satellite imagery can be analysed and processed using ATCOR 2/3, ENVI 4.7 and GIS, allowing not only a neighbourhood, city and regional scale assessment, but also generating holistic catalysing mapping typologies: game-board, rhizome, layering and drift, which are critical to ensure the integration of all parameters. The scientific inputs need to be combined not only with other disciplines but often also with existing urban plans. The connection between scientific research and existing agreed visions is critical to ensure the integration of new aspects into the plans.
Results
At the neighbourhood level the areas that have a greater heat concentration in the cities of Delft, Leiden, Gouda, Utrecht and Den Bosch are the city centres characterised by their red ceramic roof tiles, brick street paving, and canals. Several mitigation strategies could be implemented to improve the UHI effect in those areas; however, since the city centres are consolidated and listed urban areas, the mitigation measures that would be easier to implement would consist in improving the roof albedo. A consistent implementation of albedo improvement measures (improving the thermal behaviour not only of flat roofs, but also of tiled pitched roofs) of all roofs included in the identified hotspots (with an average storage heat flux greater than 90 W/m2) would help reduce the temperatures between 1.4°C and 3°C. Pre-war and post-war compact and ground-based neighbourhoods present similar thermal behaviour of the surface cover, and green neighbourhoods and small urban centres also present similar thermal behaviour.
At the city scale the analysis of 21 medium-size cities in the province of North Brabant, which belongs to the South region of the county -in relative terms the most affected by the UHI phenomenon during the heat wave of 2006-, reveals that albedo and normalised difference vegetation index (NDVI) are the most relevant parameters influencing the average nightime land surface temperature (LST). Thus, imperviousness, distance to the nearest town and the area of the cities do not seem to play a significant role in the LST night values for the medium-size cities analysed in the region of North Brabant, which do not exceed 7,700 ha in any case. The future growth of most medium-size cities of the regions will not per se aggravate the UHI phenomenon; in turn it will be the design of the new neighbourhoods that will impact the formation of urban heat in the province.
The average day LST of provincial parks in South Holland varies depending on the land use. The analysis of the average night LST varies depending of the land use of the patches. The following surfaces are arranged from the lowest to the highest temperatures: water surfaces, forests, cropland, and greenhouse areas. For each of these land uses, NDVI, imperviousness and landscape shape index (LSI) shape index influence the thermal behaviour of the patches differently. NDVI is inversely correlated to day LST for all categories, imperviousness is correlated to day LST for all areas which do not comprise a significant presence of greenhouses (grassland and built patches) and inversely correlated to LST for areas with a high presence of greenhouses (cropland and warehouses). Greenhouse surfaces have highly reflective roofs, which contribute to the reduction of day LST. Finally, landscape shape index varies depending on the nature of the surrounding patches, especially for small patches (built areas, forests and greenhouse areas). When the patches analysed are surrounded by warmer land uses, slender and scattered patches are warmer, more compact and large ones are cooler. In turn, when they are surrounded by cooler patches it is the opposite: slenderer and scattered patches are cooler and more compact and larger ones are warmer. In Midden-Delfland (1 of the 6 South Holland provincial parks), most of the hotspots surrounding the park are adjacent to grassland patches. The measure to increase the cooling capacity of those patches would consist in a change of land use and/or an increase of NDVI of the existing grassland patches.
Conclusions
Satellite imagery can be used not only to analyse the heat island phenomenom in Dutch neighbourhoods, cities and regions (identify neighbourhoods with highest surface temperature, identify impact of city size and morphology in surface temperature, calcuate average surface temperature for different land uses…), but also to suggest mitigation actions for the areas assessed. Moreover, satellite imagery is here used to generate catalysing mapping typologies: game-board, rhizome, layering and drift, ensuring that the measures proposed remain accurate enough to actualy be efficient and open enough to be compatible with the rest of urban planning priorities
