La vulnérabilité du thérapeute : un potentiel dans la relation thérapeutique
Authors: Danan Karine
Published: June 2019

La vulnérabilité du praticien est une réalité qu’il s’agit d’apprivoiser, pour la transformer en ressource. Facile à dire ; mais encore faut-il être outillé pour le mettre en œuvre ! C’est sur ce point que Karine Danan offre une contribution originale. Elle expose un protocole structuré et abouti pour aider le praticien à identifier ses vulnérabilités, les accueillir, et les mettre au service de la relation d’aide. Cet article se propose donc résolument en outil de guidance à la pratique. CL
Faire l’Ours. Jeux, enjeux et limites de la mimésis
Authors: Voisenat Claudie
Published: June 2019

Dans les Pyrénées-Orientales, trois villages célèbrent, en fin d’hiver, la fête de l’Ours. De jeunes hommes costumés et grimés en ours, entourés de chasseurs, impliquant l’ensemble de la communauté villageoise dans la représentation, parcourent les rues et poursuivent les jeunes filles qu’ils font mine d’enlever. La fête de Prats-de-Mollo, analysée ici, met en scène une série d’affrontements qui, relevant de la « feintise ludique », ont tous les paradoxes de la mimesis.
Le Petit Poucet digital ethnographié
Authors: Cochoy Frank
Published: June 2019

Dans notre monde numérisé, « Suivre les acteurs », la devise historique de l’ethnographie inspirée par la théorie de l’acteur-réseau, signifie désormais suivre les acteurs et leurs traces, et, à travers ces traces, suivre leurs dispositifs, leurs avatars, leurs identités et leurs pratiques dupliquées. Les acteurs contemporains sont comme le Petit Poucet : ils peuvent disparaître ou devenir inobservables, et laisser dans la forêt marchande des traces numériques qui fonctionnent comme les cailloux blancs et les miettes de pain de jadis, dans la mesure où on peut les suivre pour retrouver des informations sur leurs pratiques et sur leurs identités. Sur le marché de la presse examiné ici, on rencontrera une foule de Petits Poucets adultes et indépendants, lisant France Vision, un grand hebdomadaire d’information français, et visionnant (ou non) des vidéos accessibles à travers les QR codes imprimés sur ses pages. À partir de la collecte de traces numériques recueillies à l’échelle nationale au cours d’une période de 10 mois (juin 2013-mars 2014), l’article présente un ensemble de résultats montrant ce que l’on peut apprendre grâce à une ethnographie renouvelée des traces de QR codes.
Réalité virtuelle et santé mentale
Authors: Klein Nicolas , Borelle Céline
Published: June 2019

Cet article s’appuie sur l’approche proposée par Madeleine Akrich et Cécile Méadel (2004) de l’arrivée des TIC dans le domaine de la santé. À partir d’une enquête de terrain sur les usages de la TERV (thérapie d’exposition à la réalité virtuelle), il interroge les effets des usages des nouvelles technologies sur les pratiques professionnelles en santé mentale. Cet article soulève la question suivante : dans quelle mesure le recours à la TERV signe-t-il la fin d’un « art de faire » (De Certeau, 1990) des psycho-praticiens ? La TERV semble a priori impliquer une homogénéisation des pratiques, autour d’un discours stabilisé, d’un protocole standardisé et d’un cadrage de la réalité virtuelle comme outil thérapeutique. Néanmoins, une étude plus fine des pratiques permet de dépasser ce diagnostic initial en éclairant comment ce dispositif, loin de signer la fin d’un art de faire, vient plutôt l’enrichir et le renouveler. Les praticiens déploient un art de faire de la thérapie avec la réalité virtuelle, dans le face-à-face avec la technique, dans les interactions avec les patients et dans la pratique du dispositif. Cet art se structure notamment autour d’un enjeu central : l’articulation entre réel et virtuel.
Les musiques interdites. Le cas des États totalitaires : Union soviétique et Allemagne nazie
Authors: Brohm Jean-Marie
Published: June 2019

L’Union soviétique et l’Allemagne nazie ont illustré, chaque fois de manière spécifique, l’asservissement totalitaire de l’art, de la musique en particulier. Le fanatisme idéologique stalinien en URSS en traquant le « formalisme bourgeois » au nom du « réalisme socialiste ». L’antisémitisme hitlérien en stigmatisant les « musiques dégénérées », en persécutant les musiciens juifs au nom de « l’art allemand » et en organisant leur anéantissement dans les camps, notamment à Theresienstadt.
Protéger contre quoi ? Prescriptions musicales et jouissance lyrique au sein de l’église catholique
Authors: Vivès Jean-Michel
Published: June 2019

L’utilisation du chant et de la musique a, assez étonnamment, fait l’objet de réglementations très strictes – voire d’interdictions – au sein des trois religions monothéistes. En choisissant d’étudier l’introduction du castrat, puis son éviction, au sein du dispositif religieux catholique à partir du XVI e jusqu’au XX e siècle, l’auteur de cet article propose d’interroger et de cerner ce contre quoi est censée nous protéger la stricte réglementation, voire l’interdiction, de certaines pratiques musicales et vocales. Que nous révèle, in fine, cette incroyable aventure artistico-religieuse à l’occasion de laquelle on mutila des milliers d’enfants au nom d’une nécessité de faire entendre la voix des anges et de transmettre le message divin depuis une position hors-sexe ? Elle se révèle être le témoin de la violente tension entre la nécessaire jouissance lyrique qui habite tout dispositif de transmission de la parole de Dieu et sa mise à distance qui hanta durant près de deux mille ans la pratique vocale catholique. Cette petite histoire des prescriptions, injonctions et ordres concernant la pratique musicale au sein de l’Église catholique permet de rappeler que le fanatisme et les violences qui lui sont liées est la chose la mieux partagée par les religions dès que la littéralité de la transmission de la parole divine et son cortège de certitudes et d’injonctions surmoïques devient le seul enjeu de la situation religieuse.
La musique juive dans l’univers concentrationnaire de Terezin
Authors: Petit Laetitia
Published: June 2019

La musique a été pour les compositeurs et les autres déportés juifs un moyen de résistance à la terreur et surtout un moyen de lutte contre l’idéologie nazie au sein même du système concentrationnaire. On peut s’interroger sur l’existence d’une spécificité de la musique juive concentrationnaire et se demander en quoi elle marquera un tournant dans l’histoire de la musique, et ce à partir de la vie musicale à Terezin.
Development of black soldier fly larvae (Diptera: Stratiomyidae) on seafood wastes
Authors: Villazana J. , Alyokhin A.
Published: June 2019

The black soldier fly,Hermetia illucens (L.) (Diptera: Stratiomyidae) is well suited for remediating biological waste. Larvae of this species are nutrient rich, grow rapidly, and convert organic wastes while suppressing pathogens and pests. Therefore, they could be used in waste management systems and as feed for livestock and in aquaculture. The goal of this study was to test suitability of several seafood wastes from Maine processing facilities forH. illucens development in order to find alternative venues for their utilization. The following substrates were tested under laboratory conditions: dry sea cucumber, wet sea cucumber, crab meal, finfish, dry quahog, wet quahog, and sea urchin (‘wet’ and ‘dry’ refer to the original condition of the wastes while their moisture levels were similar during the experiment).H. illucens eggs were placed on wax paper above each substrate, and larval growth and survival to pupation were measured. Based on the numbers and weights of surviving larvae, substrates potentially suitable forH. illucens rearing included finfish trimmings, wet sea cucumber, dry quahog, and sea urchin. Crab meal produced large larvae (0.091±0.021 g [mean ± SE], compared to experiment-wide mean of 0.064±0.007 g) in a relatively short period of time. However, larval mortality was very high, with only 4.7±1.17 larvae surviving to prepupae, compared to experiment-wide mean of 9.78±0.63 larvae. There were dramatic differences in seemingly similar materials. On wet sea cucumber, 28.82±1.49 larvae per replication survived to pre-pupae, while on dry sea cucumber the number was only 0.33±0.01. On wet and dry quahog, the numbers of surviving larvae were 1.83±0.60 and 10.1±1.97, respectively. This highlights the importance of thorough testing of specific substrates instead of extrapolating from published data.
Botanical novelties from the Sierra de Maigualida, southern Venezuela III: revision and two new species of the genus Ilex (Aquifoliaceae)
Authors: Grande Allende José Ramón
Published: June 2019

The Sierra de Maigualida is a poorly explored mountain range in the central Guayana Shield with high levels of endemism. In the present installment, this area is further delimited and mapped, toponymy is reviewed, and the genus Ilex L. is locally reviewed, with two species, namely I. huberi J.R.Grande sp. nov. and I. maigualidensis J.R.Grande sp. nov., described as new to science. Ilex huberi sp. nov. can be distinguished by its leaf blades strongly revolute, mucronate, and with obscure secondary venation, simple dichasia, and depressed-lunate sepals; I. maigualidensis sp. nov. by its dull leaves, flowers with undeveloped styles, and capitate-subcoronate stigmata. Stem buds and cataphylls are proposed as useful characters in species delimitation within the genus, while I. magnifructa Edwin is illustrated for the first time. A key is presented to differentiate all the species of Ilex of the Sierra de Maigualida.
Development of Mobile Application for Sustainable Creative Tourism Assessment using Confirmatory Factor Analysis Approach
Authors: Suphachaimongkol Chitralada , Ratanatamskul Chavalit , Silapacharanan Siriwan , Utiswannakul Patcha
Published: June 2019

Creative tourism has received increasing attention. At present, the concept of creative tourism is still in development stage since there are few or no indicators for assessing the potential of creative tourism to area-based sustainable goals. This document aims to introduce the process of mobile application for sustainable creative tourism (SCT) model development using confirmatory factor analysis (CFA) approach. The study was divided into 4 phases. The first phase involved establishing elements, indicators and criteria drawn from some previous studies and the opinions of experts’ judgement in this study. Secondly, indicators and criteria were selected by using Delphi technique. Thirdly, the indicators and criterias were confirmed by utilizing CFA, Finally, the prototype of SCT mobile application assessment tool is proposed for SCT in this study, based on CFA. Tools for the study included: 1) structured questionnaire from reviews of literature for interviewing the expert, 2) questionnaire for Delphi techniques among the experts for collecting an opinion about the selection of the indicators, and 3) a questionnaire to assess the possibility of data collection concerning the components and indicators of SCT. 300 samples from creative tourism enterprises from all around Thailand were collected and 253 were responded. Data analysis was conducted by using descriptive statistics and CFA. The study found that SCT model consists of 8 components and 36 indicators. The finding from our research shows that it is eligible to establish the novel SCT assessment indicators. The result of SCT application model is appropriate to develop mobile application for SCT assessment tool.

Authors: Hendriwanto Hendriwanto , Kurniati Utut
Published: June 2019

The study aims at investigating students' reading fluency through mobile assisted extensive reading in effect and responses. Forty-five students (14 males and 31 females) were involved in the study. The participants were asked to read the materials of graded reading in electronic books by using their mobile phone. To measure their reading fluency, reading rate was counted in word per minute. The results show that mobile assisted extensive reading outperformed the students' reading fluency. Some participants commented that mobile based extensive reading was likely to build their reading fluency. It indicated that mobile might have the potential way not only for reading comprehension but also for reading extensively.  
Testosterone levels in men with chronic migraine
Authors: Shields Lisa B.E. , Seifert Tad , Shelton Brent J. , Plato Brian
Published: June 2019

Chronic migraine is a frequent and debilitating condition affecting 14% of the general population. This prospective observational pilot study investigated whether men with chronic migraine have lower than expected total serum testosterone levels. We identified 14 men ages 26-51 at our Institution who fulfilled the ICHD-3b criteria for chronic migraine and obtained serum total testosterone levels. The mean total testosterone level in our 14 patients was 322 ng/dL (range: 120-542 ng/dL) which is in the lower 5% of the reference range for our laboratory (300-1080 ng/dL). Men with chronic migraine had lower total testosterone levels compared to published agematched normative median values by a median difference of 62 ng/dL (P=0.0494). This finding suggests that hypothalamic regulation is altered in patients with chronic migraine. Further studies are warranted to determine whether testosterone supplementation in men with chronic migraine reduces the number of headaches or the associated symptoms of hypogonadism.
From lip-service to service delivery in local Economic development: Guidelines to set up an agency for action
Authors: Venter Marius
Published: June 2019

The Constitution of South Africa imposes a burden on municipalities to engage in local economic development. Municipal local economic development practitioners are often in doubt regarding the various mechanisms available to them to implement local economic development. This article provides insight into the processes and issues surrounding the use of an external mechanism (a private company owned by the municipality) as a local economic development agency. The lessons learnt from the Overstrand Local Economic Development Agency are compared with findings of an international study of the Organisation for Economic Co-operation and Development on 16 local economic development agencies. The article provides guidelines to local economic development practitioners to follow before, during and after the establishment of a local economic development agency.
21 years of responsible investing in South Africa: Key investment strategies and criteria
Authors: Viviers Suzette
Published: June 2019

The year 2013 marked the 21st anniversary of responsible investing (RI) in South Africa. No systematic analysis of the nature of RI strategies and criteria has, however, been conducted. Content analysis of the investment mandates of 73 RI funds has revealed that the majority of asset managers employ impact investing strategies which address social issues such as infrastructure development and economic empowerment. Semi-structured interviews with eight experts in the RI field have highlighted growing interest in impact investing and screening strategies. If RI in South Africa is to reach its full potential, then a broader range of investment strategies and criteria needs to be adopted. Asset managers can capitalise on gaps in the current RI offering by creating RI-orientated property funds, dedicated green funds, and funds which employ a best-in-sector screening strategy. A clear need for focused RI research, training and education in South Africa has furthermore been identified.
An investigation into the future of discretionary trusts in South Africa – An income tax perspective
Authors: Brink Sophia , Willemse Leonard
Published: June 2019

Trusts have long been associated with elaborate tax avoidance schemes, primarily as a result of their flow-through nature. In the National Budget the Minister of Finance indicated that the government was proposing several legislative measures during 2013/2014 regarding trusts to control abuse. At this stage the proposals are vague and confusing, but it is intimated that the conduit pipe principle may be under review as the proposals state that trusts should no longer act as a flow-through vehicle, meaning that the amounts distributed to the beneficiaries will no longer retain their original identity. The main objective of the research was to clarify the proposed changes to the taxation of trusts, to investigate the potential impact(s) of these proposals (albeit unclear and consequently based on certain assumptions), and to assess whether discretionary trusts still have a future in South Africa given these proposals. In order to meet this objective, a qualitative approach based on a literature study of pure theoretical aspects was used. It was found that should the proposals become law the beneficiaries will be worse off.
Company financial health: Financial statement users’ and compilers’ perceptions
Authors: Du Toit Elda , Vermaak Frans
Published: June 2019

Some prior studies have investigated using analyses of financial statements to reveal companies’ financial health, but the usefulness of using such analyses to reveal the financial health of companies and possible presence of accounting irregularities in South African companies needed further investigation. This study examines whether users and compilers of financial statements believe that analysing financial statements can provide clear indications of companies’ financial health. The study was conducted by means of a structured questionnaire based on statements made by experts in the field of accounting and financial statement analysis. The results from 237 respondents show that the compilers and users of financial statements are convinced of the usefulness of financial statement analysis in evaluations of companies’ financial health. This suggests that close scrutiny of a company’s financial statements, with an attitude of scepticism, has the potential to reveal possible irregularities and raise red flags about unhealthy company practices.
Lessons from South Africa’s renewable energy regulatory and procurement experience
Authors: Montmasson-Clair Gaylor , Ryan Georgina
Published: June 2019

South Africa’s Renewable Energy Independent Power Producer (REIPP) procurement programme is hailed worldwide as a model for renewable energy procurement. Its success is far from experimental and haphazard and points directly to lessons acquired prior to, and during, the launch and running of the programme. This article explores the journey to the REIPP procurement programme and draws critical lessons from the process. It discusses the success of the REIPP procurement programme in developing the renewable energy sector in South Africa, drawing seven key lessons explain this success and exploring the remaining challenges. The article shows that, despite the need for further improvements and continual optimisation, the development of the REIPP procurement programme has been a positive illustration of successful policy and regulatory learning processes.
Fuelling the economy: A critical review of liquid fuels regulation in South Africa
Authors: Mondliwa Pamela , Roberts Simon
Published: June 2019

This article reviews the regulation of liquid fuels in South Africa over the past decade. We first briefly assess the regulatory regime and how the regulatory functions have been carried out. We then consider the influence of security of supply concerns on regulation and highlight that it has favoured local refining interests rather simply ensuring supply to local fuel customers. The record of price regulation at different levels from refinery to retail is assessed, revealing the margins which had been allowed through the way in which the import parity price calculation had been done, which set prices that were higher than actual import prices would have been. The article further highlights how regulation has failed to take into account the special position of Sasol, notwithstanding the recommendations of the Windfall Tax Task Team and the reasons why the recommendations were not adopted by National Treasury based on expectations of investment. The case of natural gas provides a contrast, being subject to a recent regulatory framework, and we consider whether learnings from regulation in other parts of the value chain have been used in setting out new regulations.
Performance measurement in small and medium enterprises: South African accountants' view
Authors: Kirsten Elize , Vermaak Frans N.S. , Wolmarans Hendrik P.
Published: June 2019

Small and Medium Enterprises (SMEs) are important catalysts of economic growth, creating employment opportunities and contributing to the gross domestic product (GDP) of their respective countries. Unfortunately, SMEs suffer from a high failure rate due to SME managers’ lack of managerial knowledge and skills. SME managers also do not use performance measures which are important in business management and provide support to the managers in decision-making processes. This study contributes to the existing knowledge by determining that the use of a performance measurement tool is important in SMEs, as it can help to improve their performance and chances of survival. Accountants have the knowledge and skills to help SMEs to measure their performance and to achieve their business objectives. Accountants calculate financial ratios, explain the results and provide advice to SMEs. They, however, do not develop a Balanced Scorecard, although they perceive it to be beneficial to the SMEs.
Mapping the relationship between the primary and the secondary art market
Authors: Baur Peter , Els Gideon
Published: June 2019

The article endeavours to construct a model that links the gap between returns to an investment in ‘Fine Art’ and the ‘real’ price of the 'Fine Art' being traded. Thus the process used in creating shared value within the market for 'Fine Art' is examined. Art prices are usually set in the primary market through the auction process, which should also typically reflect an efficient way of creating shared value. As the auction process in the primary art market is not efficient; it does not create shared value as would occur in a typical free market structure. Artificial rigidities exist within the primary art market; thus the links between the primary art market and the secondary art market are shown by incorporating the concepts of the 'Value of Information' and ‘Strategic Uncertainty’ into the transmission mechanism.
SAICA's academic traineeship programme: would guidelines facilitate focused skills development?
Authors: Warffemius Petra , Kruger Lukas , Steenkamp Gretha
Published: June 2019

The South African Institute of Chartered Accountants (SAICA) developed the Academic Traineeship Programme (ATP) to give trainee chartered accountants (CAs) the opportunity to complete one of their three training years in an academic environment. The structure and guidelines of the ATP should be reconsidered given changes in the overall CA (SA) Training Programme (e.g. increased focus on the development of the prescribed competencies, especially pervasive skills) and in the academic environment (e.g. increased emphasis on research). This article presents the findings of a study that surveyed current academic trainees and found that they spend most of their time on the presentation of tutorials, marking of assessments and student consultation. The surveyed academic trainees believe that stricter guidelines for how they spend their time would be beneficial; also, they would prefer to do more lecturing and research. Guidelines are proposed based on an inclusive stakeholder model and on SAICA’s Competency Framework, which shows increased focus on research and the setting of assessments.
Genetic diversity of Hepatozoon (Apicomplexa) from domestic cats in South Africa, with a global reassessment of Hepatozoon felis diversity
Authors: Harris David J. , Halajian Ali , Santos Joana , Rampedi Kgethedi M. , Xavier Raquel
Published: June 2019

Genetic diversity within partial 18S rRNA sequences from Hepatozoon protozoan parasites from domestic cats in South Africa was assessed and compared against published data to assess global biogeographic patterns. Multiple distinct haplotypes of Hepatozoon felis were identified, as well as an unrelated Hepatozoon lineage. Hepatozoon felis genetic diversity globally is very high, indicating a likely complex of species. The recently described Hepatozoon apri from wild boars is closely related to some lineages of H. felis. Sarcocystis and Babesia parasites were also detected. Since Hepatozoon felis is apparently a species complex, potential differences between genetically distinct forms need to be assessed. The finding of an unrelated Hepatozoon indicates that felids can be infected by more species of Hepatozoonthan currently known, and that trophic interactions may increase the number of Hepatozoon species found in carnivores. Genetic screening again is demonstrated to identify previously unrecognised parasites from vertebrate hosts.
A new method to determine the aerosol optical properties from multiple-wavelength O4 absorptions by MAX-DOAS observation
Authors: Xing Chengzhi , Liu Cheng , Wang Shanshan , Hu Qihou , Liu Haoran , Tan Wei , Zhang Wenqiang , Li Bo , Liu Jianguo
Published: June 2019

Abstract. Ground-based multi-axis differential optical absorption
spectroscopy (MAX-DOAS) observation was carried out from November 2016 to
February 2017 in Beijing, China, to measure the O4 absorptions in UV and
visible bands and further to illustrate its relationship with aerosol
optical properties (AOPs) under different weather types. According to
relative humidity, visibility, and PM2.5, we classified the observation
periods into clear, light-haze, haze, heavy-haze, fog, and rainy weather conditions. There are obvious differences for measured
AOPs under different weather conditions, especially scattering coefficient
(σsca) and absorption coefficient (σsca). It was also
found that both the O4 differential slant column densities (DSCDs) at
the UV and visible bands varied in the order of clear days > light-haze days > haze days > heavy-haze days > fog days. The correlation coefficients (R2) between
O4 DSCDs at 360.8 and 477.1 nm mainly varied in the order of clear days > light-haze days > haze days > heavy-haze
days. Based on the statistics of O4 DSCDs at an elevation angle 1∘
with the corresponding linear regression between UV and visible bands of
segmental periods, the relationships between O4 DSCDs and AOPs were
established. It should mainly be clear or light-haze days when the
correlation slope is greater than 1.0, with a correlation coefficient (R2)
greater than 0.9, and O4 DSCDs mainly greater than 2.5×1043 molec. cm−2. Meanwhile, σsca and σabs
are less than 45 and 12 Mm−1, respectively. For haze or heavy-haze
days, the correlation slope is less than 0.6, with an R2 less than 0.8, and
O4 DSCDs mainly less than 1.3×1043 molec. cm−2,
under which σsca and σabs are mainly located at
200–900 and 20–60 Mm−1. Additionally, the determination method was well
validated based on another MAX-DOAS measurement at Gucheng from 19 to 27 November 2016. For more precise and accurate inversion of AOPs, more
detailed look-up tables for O4 multiple-wavelength absorptions need to
be developed. Since the ground surface AOPs were determined using MAX-DOAS observation at a 1∘ elevation in this study, we hope to highlight the potential of retrieved vertical spatially resolved AOPs being expected when multiple elevation angles of MAX-DOAS observation are used together.
Comparing Stability in Random Forest Models to Map Northern Great Plains Plant Communities Using 2015 and 2016 Pleiades Imagery
Authors: Brennan Jameson , Johnson Patricia , Hanan Niall
Published: June 2019

Abstract. The use of high resolution imagery in remote sensing has the potential to improve understanding of patch level variability in plant structure and community composition that may be lost at coarser scales. Random forest (RF) is a machine learning technique that has gained considerable traction in remote sensing applications due to its ability to produce accurate classifications with highly dimensional data and relatively efficient computing times. The aim of this study was to test the ability of RF to classify five plant communities located both on and off prairie dog towns in mixed grass prairie landscapes of north central South Dakota, and assess the stability of RF models among different years. During 2015 and 2016, Pleiades satellites were tasked to image the study site for a total of five monthly collections each summer (June–October). Training polygons were mapped in 2016 for the five plant communities and used to train separate 2015 and 2016 RF models. The RF models for 2015 and 2016 were highly effective at predicting different vegetation types associated with, and remote from, prairie dog towns (misclassification rates
Holocene and Common Era sea level changes in the Makassar Strait, Indonesia
Authors: Bender Maren , Mann Thomas , Stocchi Paolo , Kneer Dominik , Schöne Tilo , Jompa Jamaluddin , Rovere Alessio
Published: June 2019

Abstract. Indonesia is a country composed of several thousand islands, many of them small, low-lying and densely inhabited. These are, in particular, subject to high risk of inundation due to future relative sea level changes. The Spermonde Archipelago, off the coast of Southwest Sulawesi, consists of more than 100 small islands. This study presents a dataset of 24 sea-level index points from fossil microatolls, surveyed on five islands in the Spermonde Archipelago and compares these new results with published data from the same region and with relative sea level predictions from different Glacial Isostatic Adjustment (GIA) models. The newly surveyed fossil microatolls are located around the islands of Tambakulu, Suranti (both ~ 60 km offshore of Makassar city), Bone Batang and Kodingareng Keke (both located in the center of the Archipelago) and Sanrobengi (located ~ 20 km south-southwest of Makassar). Results from the near- and mid-shelf islands indicate that relative sea level between 4 to 6 ka BP was less than one meter above present sea level. The only exception to this pattern is the heavily populated island of Barrang Lompo, where we record a significant subsidence when compared to the other islands. These new results support the conclusions from a previous dataset and are relevant to constrain late Holocene ice melting scenarios. Samples from the two outer islands (Tambakulu and Suranti) yielded ages spanning the Common Era that represent, to our knowledge, the first reported for the entire Southeast Asian region.
Millennial-scale variations of sedimentary oxygenation in the western subtropical North Pacific and its links to the North Atlantic climate

Published: June 2019

Abstract. Lower glacial atmospheric CO2 concentrations have been attributed to carbon sequestration in deep oceans. However, potential roles of voluminous subtropical North Pacific in modulating atmospheric CO2 levels on millennial timescale are poorly constrained. Further, an increase in respired CO2 concentration in the glacial deep ocean due to biological pump generally is coeval with less oxygenation in the subsurface layer. This link thus offers a chance to visit oceanic ventilation and the coeval export productivity based on redox-controlled sedimentary geochemical parameters. Here we investigate a suite of sediment geochemical proxies to understand the sedimentary oxygenation variations in the subtropical North Pacific (core CSH1) over the last 50 thousand years (ka). Our results suggest that sedimentary oxygenation at mid-depths of the subtropical North Pacific intensifies during the episodes of late glacial (50–25 ka), Last Glacial Maximum (LGM) and also the interval after 8.5 ka, especially pronounced for the North Atlantic millennial-scale abrupt cold events of the Younger Dryas, Heinrich Stadial (HS) 1 and 2. On the other hand, oxygen-depleted seawater is found during the Bölling-Alleröd (B/A) and Preboreal. Our findings of enhanced sedimentary oxygenation in the subtropical North Pacific is aligned with intensified formation of North Pacific Intermediate Water (NPIW) during cold spells, while the ameliorated sedimentary oxygenation seems to be linked with the intensified Kuroshio Current since 8.5 ka. In our results, diminished sedimentary oxygenation during the B/A indicates an enhanced CO2 sequestration at mid-depth waters, along with slight increase in atmospheric CO2 concentration. Mechanistically, we speculate that these millennial-scale changes were linked to the strength of North Atlantic Deep Water, leading to intensification of NPIW formation and enhanced abyss flushing during deglacial cold and warm intervals, respectively. Enhanced formation of NPIW seem to be driven by the perturbation of sea ice formation and sea surface salinity oscillation in high latitude North Pacific through atmospheric and oceanic teleconnection. During the B/A, decreased sedimentary oxygenation likely resulted from an upward penetration of aged deep water into the intermediate-depth in the North Pacific, corresponding to a resumption of Atlantic Meridional Overturning Circulation.
A remote-sensing-based intensity–duration threshold, Faifa Mountains, Saudi Arabia
Authors: Karki Sita , Sultan Mohamed , Alsefry Saleh , Alharbi Hassan , Emil Mustafa Kemal , Elkadiri Racha , Alfadail Emad Abu
Published: June 2019

Abstract. Construction of intensity–duration (ID) thresholds and
early-warning and nowcasting systems for landslides (EWNSLs) are hampered by
the paucity of temporal and spatial archival data. This work represents
significant steps towards the development of a prototype EWNSL to forecast
and nowcast landslides over the Faifa Mountains in the Red Sea Hills. The
developed methodologies rely on readily available, temporal, archival Google
Earth and Sentinel-1A imagery, precipitation measurements, and limited field
data to construct an ID threshold for Faifa. The adopted procedures entail
the generation of an ID threshold to identify the intensity and duration of
precipitation events that cause landslides in the Faifa Mountains, and the
generation of pixel-based ID curves to identify locations where movement is
likely to occur. Spectral and morphologic variations in temporal Google
Earth imagery following precipitation events were used to identify
landslide-producing storms and generate the Faifa ID threshold (I =4.89D−0.65). Backscatter coefficient variations in radar imagery were
used to generate pixel-based ID curves and identify locations where mass
movement is likely to occur following landslide-producing storms. These
methodologies accurately distinguished landslide-producing storms from
non-landslide-producing ones and identified the locations of these
landslides with an accuracy of 60 %.
"Vindicación Feminista". Un caso paradigmático de exclusión en la historia del periodismo en España
Authors: Varela Menéndez Nuria
Published: June 2019

La historia del periodismo español continúa ciega al género. Las mujeres periodistas no aparecen -ni sus nombres, ni sus trabajos, ni sus aportaciones-, en el relato general y tampoco tienen presencia en relatos específicos, inexistentes, tanto en los planes de estudios como en los manuales y textos de referencia. El relato de la historia del periodismo español, en realidad, es un relato de exclusión. En este artículo se propone el ejemplo de Vindicación Feminista, la revista feminista aparecida en la Transición, como paradigma de dicha exclusión básicamente, por tres razones. En primer lugar, por el momento de su nacimiento, especialmente notable desde el punto de vista social, político y mediático. En segundo lugar, porque en sus páginas escribieron las periodistas más destacadas de la época, en realidad, buena parte de las periodistas españolas más destacadas de la segunda mitad del siglo XX. Y, en tercer lugar, porque adelantó, en sus reportajes, los temas más relevantes y polémicos para la democracia que anunciaba la Transición, temas que aún están presentes en la agenda política y mediática.
Indios pirenaicos en tres dimensiones: hallazgo e historia de “Euskadi”, película en relieve de Louis Lumière (1936)
Authors: Martínez Josu
Published: June 2019

En 1937, se estrenó en Paris un cortometraje tridimensional llamado “Euskadi”. Rodado con la pionera técnica de “cinéma en relief” ideada dos años antes por Louis Lumière, esta película desconocida ha estado desaparecida hasta que, en 2016 el grupo de investigación NOR de la UPV/EHU dio con ella en Paris. El presente trabajo, estudia el hallazgo y la historia de esta rareza del cine 3D, analizándola en su contexto cinematográfico (el cine francés de los 30 y la invención de Lumière), político (La guerra civil española en el País Vasco peninsular, y la tranquila calma al norte de la frontera), y cultural (los numerosos documentales realizados por cineastas extranjeros sobre el País Vasco continental).

Minería y movilizaciones sociales en Colombia: consultas populares y derecho al territorio
Authors: Revilla Blanco Marisa
Published: June 2019

Una mirada a la agenda de la movilización social en Colombia en los últimos diez años evidencia que los principales temas de conflicto social están vinculados a las luchas contra el impacto de las llamadas locomotoras del desarrollo, en el marco de las movilizaciones históricas por el derecho a la protesta y por el acceso, cobertura y calidad de los servicios sociales. Se trata de una emergente y creciente movilización en contra del modelo económico aperturista y extractivista predominante y de la cuestionada respuesta estatal a los conflictos sociales. Este artículo aborda actores y agendas de las movilizaciones en contra de la “locomotora minero-energética” y en defensa del territorio y explora los aprendizajes y expectativas de las comunidades que en contextos rurales y urbanos resisten a medidas económicas y reivindican el derecho al territorio y a una vida digna. Sin desconocer las conexiones con la dinámica latinoamericana, se subrayan las particularidades del caso colombiano, en relación con los desafíos de una ciudadanía que se levanta sobre aspectos culturales y políticos territorializados, que explora el camino de vías institucionales, como las consultas populares, proyectándolas como formas de acción contestataria más allá de las vías de hecho, en el marco de procesos organizativos de sectores subalternos que invocan la democracia participativa consagrada en la Carta Política de 1991.

“Asking them and Protesting”: Black and Puerto Rican Civic Leadership in Philadelphia Neighborhoods, 1960s–1970s
Authors: Ribeiro Alyssa
Published: June 2019

This article profiles three black and Puerto Rican neighborhood leaders of Philadelphia. Their civic efforts reveal a certain style of leadership that they used to navigate their communities through the turbulent 1960s and 1970s. They charted a middle path between identifying with the established power structure and pursuing purely oppositional politics. In addition to expanding our perception of civic leadership, these figures defy binary typologies of leadership style while demonstrating continuity at the local level. With diverse backgrounds and personalities, they created and maintained interethnic and cross-class alliances. Their accomplishments reveal how migrants could quickly become representative figures in their new communities. These leaders effectively mobilized a sense of shared group identity to build legitimacy among neighborhood residents.
A Coal Mine Underground Localization Algorithm Based on the Feature Vector
Authors: Yinjing Guo , Xianqi Song , Lei Yang , Wenhong Lv
Published: June 2019

To enhance the position estimation accuracy of an underground localization system for coal mine roadways, an algorithm based on the feature vector of received signals is presented in this paper. The algorithm includes three steps: the construction process of a feature vector database and a distance database, the vector matching process and the localization process. When a signal vector is received, it only needs to calculate the distance from the received vector to the center vector of each subset and then compare it with the data in the distance database. After multiple filtering and comparing the source of the strongest signal, the coordinates closest to the received vector are found. The experiment showed that the maximum error of this algorithm was 4 m and the average error was 1.62 m. Furthermore, within a localization error of 1 m, the X-axis localization accuracy was 98% while the Y-axis localization accuracy was 86%. Also, the algorithm took much less time compared to the KNN and WKNN algorithms, so the algorithm meets the requirements of coal mine safety systems and underground personnel localization systems.

Det offentlige arbejdsmarked under forandring
Authors: Thomsen Rikke , Høgedahl Laust , Larsen Trine Pernille
Published: June 2019

Det danske arbejdsmarked er under forandring, og det gælder også den offentlige sektor. Det offentlige arbejdsmarked har således været vidne til en række omstruktureringer, økonomiske besparelser og et væld af reformer. Skiftende regeringer har siden 1983 arbejdet med forskellige ”moderniseringsprogrammer” og New Public Management inspirerede tiltag med det formål at effektivisere og få den offentlige sektor til ’at køre længere på literen’ (Ibsen et al., 2011; Konggaard & Rod, 2018; Ejersbo & Greve, 2014). Et af de seneste tiltag er blandt andet den siddende VLAK regeringens ’Sammenhængsreform: Borgeren først – en mere sammenhængende offentlig sektor’. Moderniseringsdagsordnen er blevet mere udtalt på bagkant af den internationale økonomiske krise, som ramte Danmark relativt hårdt tilbage i 2008, og den dagsorden har på forskellig vis haft indfl ydelse på de offentligt ansattes løn og arbejdsvilkår (Mailand & Hansen, 2016). Mere end hver tredje af den danske arbejdsstyrke arbejder i den offentlige sektor fordelt på stat, regioner og kommuner. Den relativt store offentlige sektor skyldes, at det i Danmark og i resten af norden fortsat er det offentlige, som er hovedleverandør af serviceydelser til borgere, der i vid udstrækning bygger på et medborgskabsprincip. Det betyder også, at omkring 2/3 af det samlede offentlige forbrug går til løn og arbejdsvilkår til offentligt ansatte. Offentlige ansattes løn og arbejdsvilkår er derfor et afgørende forhold i den offentlige økonomi, og siden 2008 er de offentlige ansattes løn og arbejdsvilkår blevet en integreret del af udgiftspolitikken (Høgedahl, 2019). I et større europæisk perspektiv betegnes denne politiske dagsordenen som ’austerity measures’ og har afstedkommet en række økonomiske besparelser, løntilbageholdenhed og i nogle tilfælde endda lønnedgang og forringelser af offentlige ansattes arbejdsvilkår særligt i de sydeuropæiske lande som fx Portugal, Spanien og Grækenland selvom også andre europæiske landes offentlige sektor har været ramt af lignende reformtiltag (Marginson, 2014; Crouch, 2015).
Elastic–plastic deformation of single-crystal silicon in nano-cutting by a single-tip tool
Authors: Huang Ning , Yan Ying , Zhou Ping , Kang Rengke , Guo Dongming
Published: June 2019

A material removal mechanism of a single-tip tool cutting/scratch is the foundation for the analysis and prediction of the grinding process. A novel method for conducting single-tip, relatively high speed, and force-measurable nano-cutting tests with controllable cutting length are proposed to investigate the elastic–plastic deformation. Nano-cutting tests of single-crystal silicon are implemented at the cutting speeds of 0.1 m s−1 and 1 m s−1 which are close to the real grinding speed and much higher than that of single-tip tool scratch tests reported. Remarkable elastic recovery rate over 50% is observed in both cutting speeds. A semi-empirical model describing the relationship between the elastic recovery rate and residual depth is proposed. The normal force is studied in the whole cutting range. The findings of the elastic–plastic deformation behavior under relatively high cutting speed are valuable for the further mechanisms and process analysis of the ultra-fine grinding of brittle materials.

Background: The global increase in the use of antibiotics in poultry and livestock production has significantly resulted in the emergence of antibiotic resistant bacteria. There is a growing global concern of the effect of antibiotic resistance on both animals and humans. The aim of this study was to determine the antibiotic resistance profile of Salmonella typhimurium and E. coli 0157:H7 in ready to eat chicken meat in Ibadan, Nigeria.

Method: A set of 500 pieces of chicken parts were purchased from sampled eateries in Ibadan, Nigeria. Standard microbiological techniques were used to isolate Salmonella and E. coli biochemically and serologically. All confirmed isolates were subjected to in vitro antibiotic susceptibility testing against 8 antibiotics of different classes of Gram negative antimicrobial-impregnated multidisks (ABTEK)

Result: The resistance pattern revealed E. coli 0157:H7 and Salmonella isolates were resistant to 5 drugs namely; Ceftazidime, Cefuroxime, Augmentin, Nitrofurantoin and Ampicillin. Highest resistance of E. coli isolates to Augmentin and Ampicillin were indicated both having a frequency of 11 (84.6%) and least resistance to Gentamicin, Ciprofloxacin and Ofloxacin 0 (0.00%) were indicated. Three antibiotics that showed 100% sensitivity by all the isolates were Gentamicin, Ciprofloxacin and Ofloxacin.

Conclusion: The study revealed that Isolated E. coli and Salmonella strains from ready to eat chicken parts were resistant to five antibiotics; Ceftazidime, Cefuroxime, Augmentin, Nitrofurantoin and Ampicillin and very susceptible to three antibiotics namely; Gentamicin, Ciprofloxacin and Ofloxacin.
