Relating plankton assemblages to environmental variables using instruments towed by ships-of-opportunity

Undulating Oceanographic Recorders (UORs) and Continuous Plankton Recorders (CPRs) equipped with a suite of sensors were towed by merchant vessels in the North Sea between 1988 and 1991, recording a range of environmental variables. These were used to interpret the results of analyses of the plankton taken on CPR tows off the northeast coast of the UK in 1989 and in the Skagerrak and Kattegat in July 1988 and through 1989. Correlations were found between the biota and the environmental variables. The tidal front off the northeast coast of the UK and the front between the low salinity water in the Kattegat and the higher salinity water in the Skagerrak were dominant factors correlating with the distribution of the plankton assemblages. Discontinuities, defining the positions of the fronts, in the values of physical variables (temperature and, where measured, salinity and turbidity) were closely identified with geographical divisions between plankton assemblages. Measures of irradiance were found to be important on several occasions, presumably due to diel migrations of the zooplankton.

An Enactive Approach to the Design of New Tangible Musical Instruments

In this paper, we propose a theoretical framework for the design of tangible interfaces for musical expression. The main insight for the proposed approach is the importance and utility of familiar sensorimotor experiences for the creation of engaging and playable new musical instruments. In particular, we suggest exploiting the commonalities between different natural interactions by varying the auditory response or tactile details of the instrument within certain limits. Using this principle, devices for classes of sounds such as coarse grain collision interactions or friction interactions can be designed. The designs we propose retain the familiar tactile aspect of the interaction so that the performer can take advantage of tacit knowledge gained through experiences with such phenomena in the real world.

Alternative financing instruments for Spanish cooperative

The search for funding is an ongoing task of the company, which is exacerbated, particularly in times of economic crisis, affecting also to the cooperatives. Cooperative legislation available to these entities various instruments of external financing through the issuance of securities (bonds, equity securities, special shares), to them accounts are added in participation, but without much detail in the legal texts. At work we investigate their potential, by looking, especially in those last; We seek to clarify their legal status and contrast their potential as a technical instrument, alternative for funding in the area of cooperative societies. Finally, we also see the impact of the recent Law 5/2015, of promoting business financing in the cooperative sector and ended up proposing some policy adjustments.

Calibration of assessment instruments – classification in mathematics at the Universidad Jorge Tadeo Lozano

Item Response Theory, IRT, is a valuable methodology for analyzing the quality of the instruments utilized in assessment of academic achievement. This article presents an implementation of the mentioned theory, particularly of the Rasch model, in order to calibrate items and the instrument used in the classification test for the Basic Mathematics subject at Universidad Jorge Tadeo Lozano. 509 responses chains of students, obtained in the june 2011 application, were analyzed with a set of 45 items, through eight case studies that are showing progressive steps of calibration. Criteria of validity of items and of whole instrument were defined and utilized, to select groups of responses chains and items that were finally used in the determination of parameters which then allowed the classification of assessed students by the test.

Work/Leisure Balances and the Creation of a Carnival Cosmopolitanism amongst Salsa Dancers

This article presents a Carnival cosmopolitanism borne from salsa social dance leisure practice. This indirectly fostered cosmopolitanism is facilitated by significant changes in work practice allowing for new work/leisure balances. The means by which this change is brought about is through a Carnival cosmopolitanism.

A systematic review of instruments related to family caregivers of palliative care patients

Support for family caregivers is a core function of palliative care. However, there is a lack of consistency in the way needs are assessed, few longitudinal studies to examine the impact of caregiving, and a dearth of evidence-based interventions. In order to help redress this situation, identification of suitable instruments to examine the caregiving experience and the effectiveness of interventions is required. A systematic literature review was undertaken incorporating representatives of the European Association for Palliative Care’s International Palliative Care Family Caregiver Research Collaboration and Family Carer Taskforce. The aim of the review was to identify articles that described the use of instruments administered to family caregivers of palliative care patients (pre and post-bereavement). Fourteen of the 62 instruments targeted satisfaction with service delivery and less than half were developed specifically for the palliative care context. In approximately 25% of articles psychometric data were not reported. Where psychometric results were reported, validity data were reported in less than half (42%) of these cases. While a considerable variety of instruments have been administered to family caregivers, the validity of some of these requires further consideration. We recommend that others be judicious before developing new instruments for this population.
