New combinations in Campanulorchis (Orchidaceae: Epidendroideae): a reappraisal of the genus
Authors: PONERT JAN
Published: September 2017

Tribe Podochileae are a systematically highly challenging orchid group. Although the delimitation of Podochileae is relatively stable and monophyly of this tribe was confirmed by DNA-based phylogenetic analysis (Ng 2002), taxonomic categories within this group have changed frequently. Some groups are well separated morphologically and have been widely accepted as separate genera for a long time, whereas the majority of species was usually placed into a single genus Eria Lindley (1825: 904). Morphological traits have indicated polyphyly of this genus, which led some authors at various times to propose segregate genera. Nevertheless, these concepts were poorly supported by relevant data, and other authors retained these species in Eria s.l. Finally, combined DNA analysis confirmed the polyphyly of Eria (Ng 2002) and resulted in recognition of several previously neglected groups at generic level (Cribb & Ng 2005), including Campanulorchis Brieger (1981: 750).Campanulorchis was originally proposed by Brieger (1981) with the single species C. globifera Brieger (1981: 750). Seidenfaden (1982, 1992) demonstrated that this species was likely to be closely related to other species of Eria and classified it in Eria sect. Strongylaria Pfitzer (1888: 175). Later, Seidenfaden (1992) suggested separation of E. pannea Lindley (1842: 64) from remaining Indochinese species of E. section Strongylaria. Phylogenetic analyses of Ng (2002) confirmed polyphyly of the section Strongylaria. The type species of E. section Strongylaria, E. pannea, was transferred to Mycaranthes Blume (1825: 352; Chen & Wood 2009), and three of the remaining taxa were transferred to a revised concept of Campanulorchis (Ng & Cribb 2005, Cribb & Ng 2005): C. globifera, C. leiophylla (Lindley 1858: 57) Ng & Cribb (2005: 272) and C. pellipes (Riechenbach in Hooker 1890: 802) Ng & Cribb (2005: 272). Four years later Chen & Wood (2009) added C. thao (Gagnepain 1950: 503) Chen & Wood (2009: 346) because it shares many morphological characters with the other Campanulorchis species, especially with C. globifera. Finally, C. pseudoleiophylla (Wood 1981: 209) Wood (2011: 176) was added (Wood et al. 2011) because this species is morphologically similar to C. leiophylla (Wood 1981). Thus, five species were accepted in the most recent orchid classification (Chase et al. 2015, Govaerts 2017). Here I add two more species to Campanulorchis.

Published: September 2017

Cheiroseius Berlese is the second largest genus of the mite family Blattisociidae, but only two species of this genus have been reported from Brazil, C. neophalangioides Mineiro, Lindquist & Moraes and C. tennesseensis (De Leon). The following seven species are recorded for the first time in Brazil, including two new species: C. brevipes Karg, C. luizgonzagai n. sp., C. ornatus (Evans & Hyatt), C. parvipulmonis Karg, C. pugiunculus Karg and C. tuberculatus (Evans & Hyatt) and C. xerophilus n. sp. The new species are here described based on the morphology of adult females. Species of this genus occur commonly in wet habitats, together with different organisms, including mosquito larvae. The species reported in this study were collected from litter, except C. luizgonzagai n. sp., collected from Salvinia sp., a floating plant. A key for the separation of nine species now known from Brazil is provided.

Few reports have analyzed the effect of pentraxin 3 (PTX3) on platelets and their activation. We explored the association between plasma PTX3 and platelet indices. Forty-nine patients with stable coronary artery disease (CAD) were enrolled. Based on median PTX3, the study population was divided into group 1 (n = 25; PTX3 ≤ 0.98 ng/mL) and group 2 (n = 24; PTX3 > 0.98 ng/mL). Platelet indices investigated included mean platelet volume (MPV), platelet distribution width (PDW), platelets and large cell ratio (P-LCR), MPV to platelet count ratio (MPV/PC), platelet to lymphocyte ratio (PLR), and MPV to lymphocyte ratio (MPVLR). Patients with lower PTX3 had a higher lymphocyte count. Platelet count was similar in both groups. Notwithstanding, patients with higher PTX3 concentrations had elevated MPV (8.3 vs 10.0 fL; P < .001) and PDW (9.4 vs 12.4 fL; P < .001). However, the MPV/PC ratio was similar in both groups. Thromboinflammatory biomarkers (PLR, MPVLR) were also elevated in group 2. Pentraxin 3showed a strong, positive correlation with MPV ( r = .75, P < .01) and PDW ( r = .80, P < .01), and weak to moderate correlation with MPVLR. In conclusion, PTX3 is associated with larger platelet size as assessed by platelet volume indices. There is a strong correlation between plasma PTX3 level and MPV and PDW.

Authors: Muelleman Thomas , Shew Matthew , Alvi Sameer , Shah Kushal , Staecker Hinrich , Chamoun Roukouz , Lin James
Published: September 2017

The presigmoid retrolabyrinthine approach to the cerebellopontine angle is traditionally described to not provide access to the internal auditory canal (IAC). We aimed to evaluate the extent of the IAC that could be exposed with endoscopically assisted drilling and to measure the percentage of the IAC that could be visualized with the microscope and various endoscopes after drilling had been completed. Presigmoid retrolabyrinthine approaches were performed bilaterally on 4 fresh cadaveric heads. We performed endoscopically assisted drilling to expose the fundus of the IAC, which resulted in exposure of the entire IAC in 8 of 8 temporal bone specimens. The microscope afforded a mean view of 83% (n = 8) of the IAC. The 0°, 30°, 45°, and 70° endoscope each afforded a view of 100% of the IAC in 8 of 8 temporal bone specimens. In conclusion, endoscopic drilling of the IAC of can provide an extradural means of exposing the entire length of the IAC while preserving the labyrinth.
Understanding the Role of Store Image in Influencing Customer-based Brand Equity and Its Dimensions in Indian Sportswear Industry
Authors: Sharma Rajesh
Published: September 2017

Brand equity has been often referred to as the increase in brand value by virtue of its name. Researchers have argued since long that the ultimate criterion of success in brand management is understanding brand equity’s contribution towards long-term sales as well as long-term profits. Store image plays a crucial role in building brand equity for sportswear retailers in a highly competitive and dynamic Indian market, for gaining substantial market share. Consumers use store image as an evaluative criterion for decision-making concerning retail outlet selection. This research intends to understand empirically as to how store image can help in building brand equity in Indian sportswear market by using international brands as product stimuli. Data were collected through mall intercept survey in Indian capital and five north Indian cities. The regression analysis on data of 262 valid responses was used for testing the hypotheses. The findings indicate a positive and significant effect of store image but with different levels of intensity on all brand equity dimensions in Indian market, thus showing store image as a critical antecedent of brand equity. The study also developed a reliable measure of customer-based brand equity and store image by incorporating brand personality measures for measurement of brand associations.
Application of a Demineralized Cortical Bone Matrix and Bone Marrow–Derived Mesenchymal Stem Cells in a Model of Chronic Rotator Cuff Degeneration
Authors: Thangarajah Tanujan , Sanghani-Kerai Anita , Henshaw Frederick , Lambert Simon M. , Pendegrass Catherine J. , Blunn Gordon W.
Published: September 2017

Background:

The success of rotator cuff repair is primarily dependent on tendon-bone healing. Failure is common because weak scar tissue replaces the native enthesis, rendering it prone to reruptures. A demineralized bone matrix (DBM) consists of a network of collagen fibers that provide a sustained release of growth factors such as bone morphogenetic proteins. Previous studies have demonstrated that it can regenerate a fibrocartilaginous enthesis.

Hypothesis:

The use of a DBM and mesenchymal stem cells (MSCs) at the healing enthesis will result in a higher bone mineral density at the tendon insertion and will enhance the regeneration of a morphologically superior enthesis when compared with an acellular human dermal matrix.

Study Design:

Controlled laboratory study.

Methods:

Eighteen female Wistar rats underwent unilateral detachment of the supraspinatus tendon. Three weeks later, tendon repair was carried out in animals randomized into 3 groups: group 1 received augmentation of the repair with a cortical allogenic DBM (n = 6); group 2 received augmentation with a nonmeshed, ultrathick, acellular human dermal matrix (n = 6); and group 3 underwent tendon-bone repair without a scaffold (n = 6). All animals received 1 × 106 MSCs delivered in fibrin glue to the repair site. Specimens were retrieved at 6 weeks postoperatively for histological analysis and the evaluation of bone mineral density.

Results:

All groups demonstrated closure of the tendon-bone gap with a fibrocartilaginous enthesis. Although there were no significant differences in the enthesis maturation and modified Movin scores, repair augmented with a dermal matrix + MSCs exhibited a disorganized enthesis, abnormal collagen fiber arrangement, and greater cellularity compared with other MSC groups. Only repairs augmented with a DBM + MSCs reached a bone mineral density not significantly lower than nonoperated controls.

Conclusion:

A DBM enhanced with MSCs can augment rotator cuff healing at 6 weeks and restore bone mineral density at the enthesis to its preinjury levels.

Clinical Relevance:

Biological augmentation of rotator cuff repair with a DBM and MSCs may reduce the incidence of retears, although further studies are required to determine its effectiveness.

Published: September 2017

A 60-year-old female patient underwent emergency cadaveric liver transplantation. During the insertion of the pulmonary artery catheter (PAC) through the left innominate vein, advancement of the catheter was not successful and a knot occurred. An interventional radiologist performed antegrade rigid wire insertion into the PAC and succeeded in loosening the knot in the vessel. We report the successful removal of a knot through intervention without additional invasive procedures in a hemodynamically unstable patient with a coagulopathy.
Definition of process parameters for manufacturing of thermoplastic composite sandwiches – Part A
Authors: Grünewald Jonas , Parlevliet Patricia , Altstädt Volker
Published: September 2017

Thermoplastic composite sandwich structures offer great potential to meet the demands of lightweight structures for aeronautical applications. In this study, compression moulding of sandwich components, consisting of carbon fibre reinforced polyether ether ketone (CF/PEEK) skins and polyetherimide (PEI) core structures, is studied by modelling the effect of processing conditions on the properties of the sandwich structure, particularly the skin to core bond. In order to predict the skin-to-core tensile bond strength, a theoretical model is deduced, which is based on intimate contact and autohesion, the two mechanisms governing the fusion bonding process. The bond model allows the prediction of the tensile bond strength depending on the skin and core pre-heat temperatures and allows a prognostication about the expected failure mechanisms. According to the model, sandwiches manufactured with skin pre-heat temperatures above 290°C and a core kept at room temperature will feature a sufficient bond strength to fail cohesively within the core. In addition, the model predicts that pre-heating the core improves the bond strength. A verification of the model will be published in a follow-up paper.
Data-based double-feedforward controller design for a coupled parallel piezo nanopositioning stage
Authors: Feng Zhao , Ling Jie , Ming Min , Xiao Xiaohui
Published: September 2017

Vibrations as well as cross-coupling effects severely hinder fast and accurate tracking for coupled parallel piezo nanopositioning stages. In this article, a data-based double-feedforward controller is proposed to reduce individual-axis repetitive errors and cross-coupling-caused errors simultaneously. The proposed approach utilizes modeling-free inversion-based iterative control to compensate repetitive errors and data-based feedforward decoupling controller to eliminate cross-coupling effect, which has the advantages of no need for accurate identified process and alleviating the difficulty in inversion of non-minimum phase systems. Comparative experiments were performed on a piezo parallel nanopositioning stage to validate the effectiveness of the proposed controller. Experimental results indicate that the cross-coupling errors are compensated significantly and the fast and accurate tracking can be achieved via implementing the proposed controller on planar raster scanning and XY star trajectory with different tracking periods.
Reviewing the Concept of Advertising from the Print Media Perspectives
Authors: Jibril Ahmed Tanimu
Published: September 2017

In light of revisiting the notion of advertising from the perspectives of the print media, this review article found that advertisements are transgeneric and multidimensional media artefacts capable of operating at several platforms such as the cultural, economic, sociopolitical, religious and ideological spheres. It has also revealed that advertisements constitute an independent social discourse, which is culturally oriented, with remarkable influence on politics, social values, economics, lifestyles and the way people see the world around them. This review has also found that the multimodal nature of the present-day advertisements has accorded the genre some tremendous unseen power, capable of influencing people’s choices, when it comes to accepting ideas or goods and services. The review has also discussed how influential a mundane genre, such as newspaper advertisements, could be as it is used as the vehicle for constructing social and political agendas as well as promoting other topical issues in the society.
Magnetically coupled dual-beam energy harvester: Benefit and trade-off
Authors: Lan Chunbo , Tang Lihua , Qin Weiyang , Xiong Liuyang
Published: September 2017

This article investigates a dual-beam vibration energy harvester in which two piezoelectric cantilever beams are coupled by magnets. The analytical solution of such a vibration energy harvester system is derived. The dynamic responses and energy harvesting performances in quasi-linear, monostable and bistable regions are evaluated. With the analytical model validated by numerical simulation, a comprehensive parametric analysis is conducted to evaluate the effects of base excitation, ratio of natural frequencies and electromechanical coupling, revealing the benefits and limitations of the dual-beam vibration energy harvester, which was not possible before without the analytical tool. The magnetic interaction provides the nonlinearity and can achieve high-energy oscillations for both beams at the same time for power enhancement. However, the analysis also ascertains that the trade-off between the dual beams should be made given the change of base excitation, ratio of natural frequencies and electromechanical coupling. For a certain range of excitation, the increased output of one beam is always accompanied by the decreased output of the other for the high-energy oscillations in both monostable and bistable configurations. By and large, the operational bandwidth is enlarged for both beams owing to the co-occurrence of high-energy oscillations of the dual beams, while the performance of the system as a whole is somewhat restricted by the trade-off.

Published: September 2017

Objective: To evaluate randomized controlled trials (RCTs) that included interventions provided by community pharmacists for patients with type 1 and 2 diabetes, the analysis of each component of the intervention(s), and the description of the training that the pharmacists received. Data Sources: The literature research was conducted in PubMed and in the Cochrane Central Register of Controlled Trials (January 2000 to April 2016) for RCTs with interventions provided by community pharmacists for patients with diabetes. Corresponding authors were contacted about missing data and intervention and training design. Study Selection and Data Extraction: RCTs published in English or German were included if pharmaceutical care or medication therapy management was conducted by community pharmacists with diabetes patients. Basic information, intervention and training design data were extracted. Data Synthesis: The literature research resulted in 11 eligible studies for further analysis. The corresponding authors of 6 studies responded to our request and sent their raw data. The calculated meta-analytical effect of 640 analyzed patients was a hemoglobin A1C (A1C) difference of −0.66%, with a 95% CI of −0.86% to −0.45%. The analysis revealed that most intervention elements had a significant positive meta-analytical effect on the A1C values. Conclusions: Our meta-analysis suggests that community pharmacist–led interventions can improve glycemic control in patients with type 1 and 2 diabetes. The most effective intervention components were patient centered and interdisciplinary. Pharmaceutical care interventions should, therefore, include the following components: sending feedback to the physician, setting individual goals, reviewing medication, and assessing patients’ health beliefs and medication knowledge.
Challenges to Evaluating Physical Activity Programs in American Indian/Alaska Native Communities
Authors: Roberts Erica Blue , Butler James , Green Kerry M.
Published: September 2017

Despite the importance of evaluation to successful programming, a lack of physical activity program (PAP) evaluation for American Indian/Alaska Native (AI/AN) programs exists, which is significant given the high rates of obesity and diabetes in this population. While evaluation barriers have been identified broadly among AI/AN programs, challenges specific to physical activity (PA) programming are unexplored. To address this gap, a research study was conducted involving 17 in-depth interviews with evaluation staff of externally funded AI/AN PAPs. A thematic analysis revealed factors hindering meaningful program evaluation: cultural characteristics that challenge traditional evaluation, the logistics of PA programming, measurement and data collection challenges, lack of resources and support, and lack of alignment between funding agency requirements and the evaluation desired by AI/AN organizations. Some challenges are general to PAPs and others specific to AI/AN organizations. Findings identify ways to improve culturally responsive evaluation for AI/AN PAPs.
Optimizing tourist demands with utility efficient frontier
Authors: Rakotondramaro Hanitra , Botti Laurent
Published: September 2017

Mean-variance portfolio analysis leads to determine tourist demands mix but it does not provide any information regarding the risk attitude of the decision maker. In this article, we propose to fill this research gap by proposing a methodological approach which combines the portfolio theory with the utility function technique. By doing so, our approach incorporates the risk attitude of the decision maker through different values of risk tolerance. We apply this methodology on destination management framework. An illustration of its strengths is suggested by using the case study of European tourists visiting France between 2008 and 2013. Our article shows that the optimal origins mix depends on the level of risk aversion of the destination manager. Accordingly, the implications of our methodological approach are highlighted.
Aesthetico-Cultural Cosmopolitanism Among French Young People: Beyond Social Stratification, The Role of Aspirations and Competences
Authors: Cicchelli Vincenzo , Octobre Sylvie
Published: September 2017

Based on a French survey designed to understand how young people appropriate internationally disseminated cultural products, this article explores the social stratification of everyday aesthetico-cultural cosmopolitanism in France among them. Using two classification techniques (ascending hierarchical classification and k-means clustering) and a polytomic logistic regression, we demonstrate that this cosmopolitanism can be viewed along a continuum of configurations rather than in a number of pure types. We identify five configurations: inadvertent cosmopolitans, specific cosmopolitans, cosmopolitan fans, national fans and impossible cosmopolitans. These configurations are not uniformly distributed across society: socio-demographic factors do not have a single, unambiguous effect, but are in fact combined with individual resources (experiences, competences and aspirations).
Improvements in Negative Parenting Mediate Changes in Children’s Autonomic Responding Following a Preschool Intervention for ADHD
Authors: Bell Ziv , Shader Tiffany , Webster-Stratton Carolyn , Reid M. Jamila , Beauchaine Theodore P.
Published: September 2017

Abnormal patterns of sympathetic- and parasympathetic-linked cardiac activity and reactivity are observed among externalizing children and mark deficiencies in central nervous system regulation of behavior and emotion. Although changes in these biomarkers have been observed following treatment, mechanisms remain unexplored. We used MEMORE—a new approach to analyzing intervening variable effects—to evaluate improvements in parenting as mediators of changes in sympathetic nervous system (SNS)- and parasympathetic nervous system (PNS)-linked cardiac activity and reactivity among 99 preschoolers with attention-deficit hyperactivity disorder who were treated using an empirically supported intervention. Decreases in negative parenting (criticism, negative commands, physical intrusions) were associated with increases in resting respiratory sinus arrhythmia (RSA) and pre-ejection period (PEP) reactivity to incentives from pre- to postintervention. Increases in positive parenting were not associated with changes in autonomic function. These findings suggest socially induced plasticity in peripheral biomarkers of behavior and emotion regulation and underscore the importance of reducing aversive interactions between parents and children when treating externalizing behavior.
Fractal Investigation and Maximal Overlap Discrete Wavelet Transformation (MODWT)-based Machine Learning Framework for Forecasting Exchange Rates
Authors: Ghosh Indranil , Chaudhuri Tamal Datta
Published: September 2017

Foreign currency is bought and sold in the financial markets, every minute, every day, on trading days, like any commodity or stocks of companies. The players in this market are (a) people with underlying interest in foreign currency such as exporters and importers who are continuously hedging in futures or options markets, (b) speculators and (c) arbitrageurs. This paper focuses on this microeconomic flavour of foreign currency as a continuously tradable product and presents a granular framework for forecasting the exchange rate. We initially investigate year-wise inherent nature of movements of three exchange rates, namely Indian rupee/US dollar, Indian rupee/euro and Indian rupee/Japanese yen, during 2011–2016 through Mandelbrot’s single fractal model. Subsequently, maximal overlap discrete wavelet transformation (MODWT) is used to decompose the time series of the individual exchange rates. Random forest and bagging are applied on the decomposed components for predictive modelling.
Spontaneous Left Main and Right Coronary Artery Spasm in a Patient With Vasospastic Angina
Authors: Parikh Analkumar , Vacek Thomas Paul
Published: September 2017

Coronary spasm is a well-documented, though rare, condition that can mimic myocardial infarction and is usually found in only a single vessel during an event. We describe the case of a 43-year-old male with past medical history of hypertension, hyperlipidemia, tobacco abuse, and with no known coronary disease. The patient developed chest pain 3 days postadmission for primary diagnosis of psychiatric disorder. The patient had a positive stress study with moderate reversible ischemia in the anterolateral region. A subsequent coronary angiography was performed that revealed significant left main coronary obstruction with TIMI I (thrombolysis in myocardial infarction) flow. This pattern was also present in the proximal right coronary artery. Both stenoses were relieved with intracoronary nitroglycerin, revealing no significant obstructive disease and TIMI III flow. The patient was started on dihydropyridine calcium channel blocker and counseled against smoking without recurrence of angina.
The discreditation of girdite
Authors: Kampf Anthony R. , Mills Stuart J. , Rumsey Mike S.
Published: September 2017

Girdite, a mineral described byWilliams in 1979 from the Grand Central mine, Tombstone, Cochise County, Arizona, USA, has been re-examined by powder X-ray diffraction, single-crystal X-ray diffraction and electron microprobe. Type material from The Natural History Museum, London and the United States National Museum of Natural History (Smithsonian Institution) was examined. The original description of girdite is shown to have been based upon data obtained from at least two and possibly three different phases, one corresponding to ottoite and another probably corresponding to oboyerite, although the latter itself appears to be a mixture. The discreditation of girdite as a valid mineral species has been approved by the IMA-CNMNC, Proposal 16-G.
Omariniite, Cu8Fe2ZnGe2S12, the germanium analogue of stannoidite, a new mineral species from Capillitas, Argentina
Authors: Bindi Luca , Putz Hubert , Paar Werner H. , Stanley Christopher J.
Published: September 2017

Omariniite, ideally Cu8Fe2ZnGe2S12, represents the Ge-analogue of stannoidite and was found in bornite-chalcocite-rich ores near the La Rosario vein of the Capillitas epithermal deposit, Catamarca Province, Argentina. The mineral is associated closely with three other Ge-bearing minerals (putzite, catamarcaite, rarely zincobriartite) and bornite, chalcocite, digenite, covellite, sphalerite, tennantite, luzonite, wittichenite, thalcusite and traces of mawsonite. The width of the seams rarely exceeds 60 μm, their length can attain several 100 μm. The mineral is opaque, orange-brown in polished section, has a metallic lustre and a brownish-black streak. It is brittle, and the fracture is irregular to subconchoidal. Neither cleavage nor parting are observable in the sections. In plane-polarized light omariniite is brownish-orange and has a weak pleochroism. Internal reflections are absent. The mineral is distinctly anisotropic with rotation tints varying between brownish-orange and greenish-brown. The average result of 45 electron-microprobe analyses is Cu 42.18(34), Fe 9.37(26), Zn 5.17(43), In 0.20(6), Ge 11.62(22), S 31.80(20), total 100.34(46) wt.%. The empirical formula, based on Σ(Me + S) = 25, is Cu8.04(Fe2.03In0.02)Σ2.05Zn0.96 Ge1.94S12.01, ideally Cu8+Fe2+Zn2+Ge24+S122-. Omariniite is orthorhombic, space group I222, with unit-cell parameters: a = 10.774(1), b = 5.3921(5), c = 16.085(2) Å, V = 934.5(2) Å3, a:b:c = 1.9981:1:2.9831, Z = 2. X-ray single-crystal studies (R1 = 0.023) revealed the structure to be a sphalerite derivative identical to that of stannoidite. Omariniite is named after Dr. Ricardo Héctor Omarini (1946–2015), Professor at the University of Salta, for his numerous contributions to the geology of Argentina.

Development of cognitive universal learning activities for students while solving tasks with a parameter
Authors: Журавлева Н. , Zhuravleva N. , Шашкина М. , Shashkina M.
Published: September 2017

The article highlights the problem of developing universal learning activities of students at Mathematics lessons. It is proposed to use the didactic potential of tasks with a parameter developing cognitive universal learning activities while studying mathematics. By solving tasks with a parameter, students need to be able to show quite advanced logical reasoning, to work accurately with the range of permissible values of the variable and the parameter, i.e. they should demonstrate high level of logical thinking and mathematical culture. Therefore, it can be argued that when using such tasks in the process of teaching mathematics, it is possible to form and develop logical, symbolic and exploratory learning activities (according to A.G. Asmolov). The authors present a set of training exercises for the development of cognitive universal learning activities on the basis of various tasks with a parameter used during the Unifi ed State Examination mass testing in 2017.

Diagnosis of parasitic infections in animals is an interesting task that can be developed by veterinary nurses. To perform direct identification of parasites, particularly ova present in faeces, it is possible to use faecal smears, flotation and sedimentation tests. Faecal flotation is fast and inexpensive, and can be quickly implemented as a measure for infection control. Herewith we describe the Willis method, one of the most used flotation methods.
Why you should join the end BSL campaign
Authors: Gaines Samantha
Published: September 2017

As veterinary professionals and animal experts we all understand that aggression is a complex behaviour and whether or not a dog uses aggression is influenced by a range of factors including how they are bred, reared and experiences throughout their lifetime. Breed is not a good predictor of risk. But in the UK, under the Dangerous Dogs Act, breed specific legislation prohibits the ownership of four types of dog despite there being no specific research to demonstrate that they are more aggressive towards people than other dogs. The RSPCA believes it is wrong to punish innocent dogs simply because of their appearance and is calling for a change to the law.
Fashion: From attitudes to poses
Authors: Evans Caroline
Published: September 2017

Borrowing some of Aby Warburg’s methods from his Mnemosyne Atlas, this paper experiments with an anti-linear, non-teleological method of writing fashion history. It investigates fashion movement, gesture and pose, and their afterlife in images and objects. It thus looks at the intersection of time and the gesture, particularly in relation to the idea of the ‘now’, a central organising principle of fashion. To this end, it juxtaposes images of the body in motion from a wide range of sources, including scientific photography, etiquette manuals and fashion magazines. Spanning three centuries, though not chronologically, the images show a range of activities: not only fashion posing, but also tennis-playing, duelling, dancing, military marching, social gestures, and going to the races. The paper proposes that each image is charged with some quality or attribute that is also immanent in one or more of the others, even though they have no causal or temporal relationship.
Metadata: New perspectives on Aby Warburg’s ‘critical iconology’
Authors: von Müller Johannes
Published: September 2017

The article reassesses the renown ‘critical iconology’ practiced by Aby Warburg and confronts it with recent theories regarding metadata and the curatorship of information. A close examination of Robert Kitaj’s portrait Warburg as a Maenad (1961–62) affirms Warburg’s ‘combinatory experiments’ (Christopher D. Johnson) to be a main characteristic of his practice. Warburg seems to have operated by applying what can now be described as metadata to the processes of transmission of culture he was accessing in form of migrating images. Further, the insights he was able to gain, namely his famous notion of the ‘Pathosformel’, may have to be considered as a specific form of metadata too. This is of particular interest acknowledging that in the digital world the migration of images takes mainly place in the realm of metadata. Hence ideas put forward by Warburg are able contribute to a deeper understanding of such phenomena.
Speculating on the biography of an apparatus
Authors: Hennig Anke
Published: September 2017

In this article I will look at literary imagination and the ways it is undermined and transformed by its relationship to apparatuses. I will compare the apparatus of Aby Warburg’s library with Peter Dittmer’s recent poetic apparatus Die Amme (1992–2006) in order to find out how poetics gets trapped by, and responds to, the challenge of apparatuses by employing the logistics of writing. A key concern of this article is to determine the role that speculation plays in poetics, in the apparatuses that govern writing, and in the economics of both.
Hades as an accumulation of tertiary retentions
Authors: Stiegler Bernard
Published: September 2017

This article examines Aby Warburg’s enterprise as an anamnesis, as a question of memory in exosomatisation in relation to the pharmakon. Here the pharmakon is considered as a ‘support’ in relation to questions of ‘care’ and as a therapeutics, prescribing the way by which such a pharmakon can become or remain curative, rather than toxic. The discussion looks at how the pharmakon makes possible the transmission of the condition of knowledge, that is: as a preindividual milieu that contains, retains and re-activates traumatypes, providing opportunities for bifurcations in the future. Warburg’s employment of photographic montage is considered as an exploration of pharmacological possibilities inherent to tertiary retentions and providing the condition for revenance. Such revenance is proposed as the return of the serpent in absentia: as a new form of tertiary retention that today appears as digital tertiary retention. At stake is the libido’s economisation, interactivity and algorithmic governmentality all of which effect the faculties for dreaming, imagination and knowledge.
Integração dos métodos de georradar e indução eletromagnética para o mapeamento de grutas: aplicação à lapa do sono - Arrábida
Authors: Caldeira B. , Oliveira R. J. , Rocha L. , Borges J. F. , Neves S. , Fernandes R.
Published: September 2017

Neste trabalho apresentam-se os resultados da aplicação da geofísica ao mapeamento de uma secção da Lapa do Sono - Serra da Arrábida (Sesimbra), que se sabe ter tido ocupação funerária na época do Neolítico antigo e atualmente se apresenta extremamente obstruída por sedimentos. Foram escolhidas duas técnicas frequentemente utilizadas na prospecção da subsuperfície em ambiente arqueológico, o Georradar (GPR) e a Indução Eletromagnética de baixa frequência (EM). O difícil estado do terreno e os condicionalismos colocados em defesa da proteção da natureza impuseram um programa de aquisição de dados segundo um paradigma um pouco diferente do habitual. A metodologia seguida para a obtenção de resultados teve que se basear numa análise exaustiva sobre um limitado número de perfis modelados, utilizando distintas sistemáticas de processamento 2D, implementadas para despistar os principais fatores de erro. Os resultados permitem delinear a gruta principal inserida num meio cársico, extensamente fragmentado, principalmente nas áreas de cobertura da cavidade. Também se recolheram indícios de outras cavidades menores contiguas à gruta principal que podem estar a ela ligadas através de galerias menores preenchidas por sedimentos. A partir da interpretação dos resultados foi feita a avaliação da espessura de sedimentos acumuladas na periferia da gruta, sob os perfis amostrados.
Datação direta e análise de paleodietas dos indivíduos da Anta de Cabeceira 4.ª (Mora, Évora)
Authors: Carvalho António Faustino , Rocha Leonor
Published: September 2017

A datação por radiocarbono e a análise de carbono e azoto sistemáticas dos três indivíduos exumados da Anta de Cabeceira 4.ª (Mora, Évora), indicaram uma cronologia antiga dentro do megalitismo regional e padrões paleodietéticos similares aos anteriormente obtidos no Algar do Bom Santo (Alenquer, Lisboa), os quais indicam percentagens relativamente elevadas (20-25%) de alimentos de origem estuarina/ribeirinha, confirmando assim, pelo menos em boa parte, o modelo interpretativo construído com base no estudo da referida gruta estremenha.
Análisis arqueométrico de cerámicas metalúrgicas del III milenio A.N.E. del asentamiento de Cabezo Juré (Alosno, Huelva)
Authors: Inácio N. , Nocete F. , Nieto J. M. , Bayona M. R.
Published: September 2017

El concepto y la percepción de la metalurgia prehistórica, de su desarrollo cronológico, tecnológico y social, ha sido modificado desde la evaluación y análisis de la actividad metalúrgica en el asentamiento de Cabezo Juré. En este trabajo se presentan los resultados de la definición de los procesos tecnológicos asociados a la producción de instrumentos cerámicos vinculados al proceso metalúrgico (crisoles y vasijas de reducción), mediante la aplicación de una metodología de evaluación empírica basada en análisis petrográficos y químicos. Los resultados del análisis arqueométrico sobre estas cerámicas metalúrgicas sugieren la utilización de arcillas locales para su manufactura, similares a las empleadas en la cerámica de uso doméstico. Sin embargo, se ha observado la existencia de elecciones tecnológicas diferenciales, de cara a soportar los altos gradientes térmicos a los que debían estar sometidos durante el proceso metalúrgico.
Bases de un modelo conceptual para decidir hechos
Authors: Coloma Correa Rodrigo
Published: September 2017

El presente texto se ocupa de algunos problemas que afectan la gestión de las pruebas y de los argumentos probatorios en sede judicial. Al respecto se proponen las bases de un modelo conceptual, en cuanto recurso que estandariza las posibilidades de ejecución de las tareas propias de un campo de trabajo. En el mundo de los jueces y de los abogados, los modelos conceptuales simplifican los problemas por la vía de declarar irrelevantes asuntos de detalle y, coetáneamente, de organizar eficientemente los distintos componentes implicados en la toma de decisiones. El concepto básico desde el cual se sugiere construir un modelo para gestionar los problemas probatorios es el de «hecho (probado)», entendido como un artefacto lingüístico que adscribe conductas jurídicamente relevantes y que supera un proceso de validación institucional.
El control de la actividad judicial y las teorías jurídicas actuales
Authors: Hernández Marín Rafael
Published: September 2017

El pensamiento jurídico actual está dominado por teorías acerca de diferentes aspectos de la actividad judicial que no permiten controlar si los jueces cumplen o no las obligaciones que el Derecho les impone. Entre dichas teorías figuran teorías acerca de cuáles son las obligaciones de los jueces, teorías acerca de la motivación de las decisiones judiciales, teorías ontológico-jurídicas acerca de la naturaleza del Derecho, teorías relacionadas con la aplicación del Derecho y teorías de la interpretación del Derecho.
Sobre la opacidad referencial y la ambigüedad de dicto/de re en el Derecho
Authors: Rodríguez-Toubes Muñiz Joaquín
Published: September 2017

Los contextos lingüísticos llamados opacos ocultan la referencia de los grupos nominales y pueden causar ambigüedad, que al manifestarse en las leyes adquiere relevancia jurídica. La opacidad referencial se comprueba en enunciados que cambian su valor de verdad cuando se sustituye un nombre por otro con la misma extensión. En tales situaciones la intensión cobra protagonismo, y por ello formular enunciados jurídicos en contextos opacos hace más visible e inteligible la atribución intensional característica del derecho. Por otra parte, la opacidad referencial suscita un tipo especial de ambigüedad, de raíz pragmática y estructura lógica, en la que un mismo grupo nominal admite una lectura inespecífica o de dicto (según lo dicho) y otra específica o de re (según la cosa). Varios ejemplos tomados del Código Penal español muestran la importancia de percibir esta ambigüedad.
Muertes y resurrecciones del positivismo jurídico: una crisis de doscientos años de duración
Authors: Lloredo Alix Luis
Published: September 2017

El objetivo de este artículo es mostrar que el positivismo jurídico ha vivido en crisis desde su mismo nacimiento, a principios del siglo XIX, y no solo desde la oleada neoconstitucionalista. En primer lugar se examinarán los problemas de las aproximaciones conceptuales al problema del positivismo y se defenderá la necesidad de un acercamiento histórico para comprender la cuestión de si el iuspositivismo se encuentra verdaderamente obsoleto. En segundo lugar se pasará revista a las sucesivas crisis que ha experimentado esta corriente a lo largo de sus doscientos años de historia, y se verá cómo ha ido adaptándose a todos esos embates. Por último se argumentará que, desde ese punto de vista, el ataque post-positivista no representa una impugnación radical de sus planteamientos, sino una reorientación que corre pareja con transformaciones ideológicas profundas del orden global.
Multivariate statistics and visualisation in earth science
Authors: Irawan Dasapta Erwin
Published: September 2017

It's not exist until it's shown on a map.

Earth scientists are known to have a close relationship with maps. But since a long time a go, they also known to use statistics to support their claims. However, this strategy has not been applied extensively in Indonesia. More scientists still separate the spatial component with the statistical component in an geological analysis, for instance. Moreover, given the heterogenity of a geological environment, then the analysis is more complex than ever. Multivarible/multi parameters environment is the cause. This collection is another effort that I made to share multivariate statistics and it's various usage for earth science or geoscience. 

I started with 79 papers in this case using several keywords listed in the description. I only selected documents with DOI link, to ensure that the doc is in form of a paper or an abstract. It covers mostly principal component analysis (PCA) and cluster analysis (CA) in soil, geochemistry, and water quality researches.

Now anyone could apply multivariate statistics along with pretty and informative visualisation using free tools like R and Python, like this blog post showing an example of PCA using R. 

As additional reference, I also recommend the visitor to have a look at Basic statistical concepts and methods for earth scientists, a USGS open report, writtern by Ricardo A. Olea in 2008.
