RRS "Charles Darwin" Cruise 169, 17 Feb-19 Mar 2005. Hydrothermal exploration of the southern Mid-Atlantic Ridge
The principal objective of this cruise was to identify the first site or sites of high temperature hydrothermal venting anywhere on the southern Mid-Atlantic Ridge, to characterize their geological setting, preliminary chemical nature and to identify, where possible, the nature of any vent-endemic species that might inhabit such vents to investigate whether this ridge system might represent a new biogeographic province. Initially we used the TOBI deep-tow sidescan system equipped with a CTD system and optical backscatter sensors, together with Miniature Autonomous Plume Recorders (MAPRs) to identify two new sites in which diagnostic chemically- and particle-laden plumes indicated the presence of high-temperature hydrothermal venting. Subsequently, we used the ABE autonomous underwater vehicle to (1) locate the core of one of these hydrothermal plumes, (2) obtain a detailed map of the underlying seafloor and (3) photograph three discrete hydrothermal sites (2 black-smoker systems, 1 diffuse-flow) and their associated ecosystems. A series of CTD stations were occupied for water column investigations and a number of rock-coring and dredging stations were also undertaken to provide groundtruthing of sidescan sonar images of the Mid-Atlantic Ridge seafloor
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
A Parson in the Era of Transformations
teologia pastoralnaArtykuł został poświęcony problematyce kierowania parafią przez proboszcza w epoce przemian, jakie dokonują się w Europie Środkowo-Wschodniej. Zmiany te są wielorakie i złożone. W artykule skoncentrowano się na zmianach społeczno-kulturowych i religijnych, które stanowią zasadnicze tło posługiwania proboszcza. Sprawiają one, że dotychczasowy model kierowania wspólnotą parafialną staje się niewystarczający i nieadekwatny do współczesnych wyzwań. Odwołując się do teorii organizacji i kierownictwa podjęta została próba wskazania na kierunki działań proboszcza, ukierunkowane na to, aby parafia stawała się coraz bardziej wspólnotą ewangelizującą. W oparciu o nauczanie Kościoła i tę teorię zauważone zostały cechy proboszcza, szczególnie przydatne do kierowania parafią. Zwrócono także uwagę na niektóre sposoby formacji kapłańskiej, mogące pomóc proboszczom skutecznie realizować ich posłannictwo.This paper is devoted to the issues concerning the leadership of a parson over his parish in the era of transformations which are taking place in the Central and Eastern Europe. These transformations are multiple and complex. The author of the paper focuses on the socio-cultural and religious transformations which constitute the essential background for the parson’s ministry. These transformations result in the fact that the previous model of leadership in the parish community is not sufficient or adequate to the contemporary challenges. On the basis of the theory of organization and leadership, the attempt was made to indicate the directions of the parson’s work which are to result in the transformation of a parish so that it could become more of an evangelizing community. On the basis of the teachings of the Church and this theory, the author indicated the features of a parson which are particularly vital in the leadership in a parish. The attention was also drawn to some ways of the priest’s formation which can help parsons to effectively pursue their mission
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Uso de problemas de Parson no ensino de programação introdutória
This work aims to explore the use of Parson's problems in teaching introductory programming. Parson's problems are a drag-and-drop type of programming exercise. Students receive blocks containing unorganized code snippets and need to organize them correctly to solve the proposed challenge. This type of activity aims to reduce the cognitive load of problems that can overwhelm novice students, such as writing code from scratch. In this work, different types or variations of Parson's problems were cataloged through a systematic literature mapping (MSL) and learning gains reported in research.Este trabalho tem como objetivo explorar o uso de problemas de Parson no ensino de introdução à programação. Os problemas de Parson são um tipo de exercício de programação baseado em arrastar e soltar blocos. Os alunos recebem blocos contendo trechos de código desorganizados e precisam organizá-los corretamente para solucionar o desafio proposto. Esse tipo de atividade tem o objetivo de reduzir a carga cognitiva dos problemas capazes de sobrecarregar os alunos novatos, como por exemplo escrever o código do zero. Neste trabalho foram catalogados diferentes tipos ou variações de problemas de Parson através de um mapeamento sistemático da literatura (MSL) e os de ganho de aprendizagem relatados em pesquisas.1Nã
A hidden Markov model-based acoustic cicada detector for crowdsourced smartphone biodiversity monitoring
In recent years, the field of computational sustainability has striven to apply artificial intelligence techniques to solve ecological and environmental problems. In ecology, a key issue for the safeguarding of our planet is the monitoring of biodiversity. Automated acoustic recognition of species aims to provide a cost-effective method for biodiversity monitoring. This is particularly appealing for detecting endangered animals with a distinctive call, such as the New Forest cicada. To this end, we pursue a crowdsourcing approach, whereby the millions of visitors to the New Forest, where this insect was historically found, will help to monitor its presence by means of a smartphone app that can detect its mating call. Existing research in the field of acoustic insect detection has typically focused upon the classification of recordings collected from fixed field microphones. Such approaches segment a lengthy audio recording into individual segments of insect activity, which are independently classified using cepstral coefficients extracted from the recording as features. This paper reports on a contrasting approach, whereby we use crowdsourcing to collect recordings via a smartphone app, and present an immediate feedback to the users as to whether an insect has been found. Our classification approach does not remove silent parts of the recording via segmentation, but instead uses the temporal patterns throughout each recording to classify the insects present. We show that our approach can successfully discriminate between the call of the New Forest cicada and similar insects found in the New Forest, and is robust to common types of environment noise. A large scale trial deployment of our smartphone app collected over 6000 reports of insect activity from over 1000 users. Despite the cicada not having been rediscovered in the New Forest, the effectiveness of this approach was confirmed for both the detection algorithm, which successfully identified the same cicada through the app in countries where the same species is still present, and of the crowdsourcing methodology, which collected a vast number of recordings and involved thousands of contributors.</p

Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

From parson to professional: the changing ministry of the Anglican clergy in Staffordshire, 1830-1960
From 1830 to 1960 the parish ministry of the clergy of the Church of England underwent a transformation, which was expressed in the gradual abandonment of the parson model and the adoption of the professional model. Staffordshire provides a good case-study area because of its wide variety of urban and rural parishes where this development can be assessed. Amongst the many causes of the change, the population size of the parishes and the sources of clerical funding are considered to be crucially important. The evidence suggests that where parishes exceeded 2000 people and where the worshiping community became the main provider of financial support, the parson model was increasingly difficult to operate. Out of necessity, and sometimes subconsciously, the clergy developed a model with significant professional features, even though the parson model continued to be promoted as the ideal. There was a narrowing of the remit of the clergy and within their local communities they were less involved and less influential. If as a consequence the incarnational aspect of local ministry has been eroded then there are far reaching implications. This study shows how practical circumstances, such as those that relate to geography and economics, although not always recognised, have an important effect upon the practice and the theology of ministry
