Improvisation théâtrale et maîtrise du changement : l’entreprise face au risque du développement personnel
Authors: Gléonnec Mikaël
Published: July 2017

L’improvisation théâtrale, lorsqu’elle est utilisée en entreprise comme technique manipulatoire de développement personnel, induit des risques tant pour les individus formés que pour l’organisation. La maîtrise de ces risques est tributaire du cadre éthique auquel se réfère l’intervenant qui conçoit et anime les séances. Si certains intervenants désengagent leur responsabilité, d’autres mettent en place des dispositifs de médiation afin de préserver les individus et l’entreprise des conséquences possibles de leur action. Se pose, in fine , la question de la compatibilité d’outils manipulatoires de développement personnel avec le processus de surveillance et de maîtrise des ressources à l’œuvre dans l’entreprise.

Authors: Ha Suk-Gyu , Suh Young-Woo , Kim Seung-Hyun
Published: July 2017

Purpose:

To describe the clinical features and surgical outcome of A-pattern exotropia combined with dissociated vertical deviation and superior oblique overaction.

Methods:

The medical records of patients with A-pattern exotropia combined with dissociated vertical deviation and superior oblique overaction who underwent horizontal muscle surgery alone or in combination with superior oblique muscle weakening surgery were retrospectively reviewed. The patients were divided into two groups according to their surgery: the horizontal muscle surgery alone group and the horizontal muscle surgery with bilateral superior oblique weakening surgery (combined surgery) group. The preoperative clinical features and postoperative surgical outcomes at the patients' final follow-up visits were analyzed.

Results:

A total of 40 patients were included. The mean age at diagnosis was 5.5 ± 4.6 years. Amblyopia and latent nystagmus were observed in 18 (45%) and 10 (25%) patients, respectively. Six (15%) patients were associated with delayed development and hemiplegia. The mean angle of exodeviation was 27.7 ± 11.2 and 28.5 ± 10.9 prism diopters (PD) for distance and near, respectively. The mean degree of superior oblique overaction was 1.9 ± 1.1 and asymmetrical dissociated vertical deviation was observed in 24 (60%) patients. At the final follow-up visit, the horizontal angle of deviation was not significantly different between the groups. The success rates were 57.1% and 80% in the horizontal muscle surgery alone and combined surgery groups, respectively. These differences were statistically significant (
P
= .04).

Conclusion:

Amblyopia was common and the prognosis of binocularity was poor in triad exotropia. Some patients had neurological deficits. The surgical success rate in this study was variable, ranging from 57.1% to 80%.

Rosa Parks con Judith Butler: performatividad individual y acción colectiva
Authors: Pérez Navarro Pablo
Published: July 2017

El presente artículo se desarrolla en dos direcciones temporales opuestas. En la primera recurro a la contracultura drag negra y latina de los Estados Unidos para releer la negativa de Rosa Parks a ceder su asiento en el autobús. A continuación, se plantea una genealogía queer de los usos de la teatralidad en las formas contemporáneas del activismo urbano. A partir del encuentro entre ambas líneas temporales defiendo, en diálogo con la obra reciente de Judith Butler, la importancia de la dimensión performativa de las intervenciones individuales en espacios de protesta para entender el alcance movilizador de la acción colectiva.
A (difícil) relação do movimento Católicas pelo Direito de Decidir e a Conferência Nacional dos Bispos do Brasil: reflexões em torno do caso da Campanha da Fraternidade de 2008
Authors: da Silva Naiara Alves 
Published: July 2017

Em 1993 chegava ao Brasil Católicas pelo Direito de Decidir (CDD), organização não-governamental assumidamente feminista e de confissão católica. A entidade começou a funcionar em prédio de propriedade da Igreja Católica e por isso supunha-se uma relação amistosa com a CNBB – Conferência Nacional dos Bispos do Brasil. A Conferência é reconhecida, desde a sua criação, em 1952, como entidade de viés progressista no tocante às questões econômicas e sociais do país. O engajamento lhe valeu, inclusive, reação muito negativa nos anos em que o país atravessava uma ditadura militar, devido à postura crítica de diversos de seus bispos que posteriormente converteu-se na orientação oficial da instituição. No entanto, a agenda progressista do MCPDD entrou em rota de colisão com a postura assumida pela CNBB em certos episódios específicos da cena nacional. O objetivo do artigo é apresentá-los.

La métaphore du féminin contestataire chez Damiela Eltit
Authors: Deville Hélène
Published: July 2017

Ce travail vise à situer la production littéraire de Diamela Eltit au sein d'une scène culturelle qui émerge dans les années 80 au Chili en réaction d'une part à l'autoritarisme du régime militaire, d'autre part à la domination masculine dans l'espace littéraire. Les autrices et critiques axent leur stratégie d'insertion et de résistance sur la métaphore du féminin, empruntée au féminisme international, qu'elles s'approprient en la dénaturalisant et en la dotant d'une force politique. Elles conjuguent cette posture différentialiste avec une ambition d’indifférenciation et de prolifération des genres et des identités. Ainsi, elles saisissent l'enjeu majeur du féminisme aujourd'hui, interroger son sujet dans sa spécificité et sa multiplicité.
Electrodeposited Copper-Graphite Composites for Low-CTE-Integrated Thermal Structures
Authors: Dwarakanath Shreya , Raj P. Markondeya , Demir Kaya , Smet Vanessa , Sundaram Venky , Tummala Rao
Published: July 2017

Emerging high-power and high-temperature electronic modules require thick copper structures for power supply, thermal vias, heat spreaders, and also as carriers or lead frames for high-power packages. Such structures should coexist with glass and other substrates with low coefficient of thermal expansion (CTE) to meet high-temperature performance, dimensional stability, and superior device interconnection reliability with low stresses and warpage. The primary challenge with these packages arises from the CTE mismatch between the conductors and the substrates. Cu-graphite composites with glass-matched CTE are explored to address this challenge through analytical modeling of properties such as CTE, Young's modulus and thermal conductivity, finite-element-modeling predictions of glass warpage and stresses, process development to deposit copper-graphite composite films with high graphite loading of 64 vol. %, and warpage measurements using shadow moiré. Results indicate that Cu-graphite composites can mitigate the warpage and stress issues in high-temperature and high-power packages.
Reliable Young's Modulus Value of High Flexible, Treated Rolled Copper Foils Measured by Resonance Method
Authors: Kammuri Kazuki , Miki Atsushi , Takeuchi Hiroki
Published: July 2017

Smartphones and tablets require very high flexibility and severe bending performance ability of the flexible printed circuits (FPCs) to fit into their thinner and smaller body designs. In these FPCs, the extraordinary highly flexible, treated rolled-annealed (RA) copper foils have recently used instead of regular RA foil and electrodeposited foils. It is very important to measure the Young's moduli of these foils predicting the mechanical properties of FPCs such as capabilities of fatigue endurance, folding, and so on. Even though the manufacturers use IPC TM-650 2.4.18.3 test method for measuring Young's modulus of copper foils over many years, where Young's modulus is calculated from the stress–strain (S–S) curve, it is quite difficult to obtain the accurate Young's modulus of metal foils by this test method. The S–S curves of copper foils always exhibit a large degree of scattering. In order to cope with the issue, “Resonance method,” using the resonance frequency of a specimen, is proposed to measure a much more accurate Young's modulus. The comparison is made between IPC TM-650 2.4.18.3 and the resonance method in view of calculation of Young's modulus accuracy. It is found that Young's modulus values measured by the resonance method were closer to theoretical values than those measured by the conventional method. In addition, the experimental data of fatigue life are used to support the accuracy of Young's modulus values measured by the resonance method.
St Luke’s Anglican Church in Ikwerreland, Nigeria (1904–2014)
Authors: Odili Jones U. , Lawson-Jack Elizabeth
Published: July 2017

Over the decades, there has been a paradigm shift in interests, approaches and methods in African Christian Historiography. There is a need for a circumscribed study and documentation of people’s engagement and involvements in the Church in Africa. This study illuminates the roles lay agents play in the advent, growth and development of St Luke’s Anglican Church, Rumuadaolu. Using the historical and sociological methods of inquiry into a religious phenomenon, this study reveals that about two-thirds of the indigenes of Rumuadaolu are Anglicans. This is because of the amiable activities of lay agents in that community. This study in addition to providing an in-depth documentation of the history of St Luke’s Anglican Church points out gray areas that the church authority and members of the St Luke’s Anglican Church, Rumuadaolu community are to note and effect necessary changes if the St Luke’s Anglican Church has to fulfil her divine mission in Rumuadaolu. Members of the church, St Luke’s Anglican Church, Rumuadaolu community and scholars who wish to have a complete view of the turn of events in African Christian historiography would find this study very important.
Relationship between age and brainstem allometry in the African grasscutter (Thryonomys swinderianus Temminck, 1827)
Authors: Ibe Chikera S. , Ikpegbu Ekele , Nzalak Oliver
Published: July 2017

Allometric values of brainstem structures were evaluated in African grasscutters Thryonomys swinderianus (n = 27). Brain samples were extracted from 9 animals each of 3 days (neonates), 72 days (juveniles) and 450 days of age (adults). The midbrain, pons and medulla oblongata were separated from each brain sample and dimensions and weights obtained. The weights of the midbrain in the neonate, juvenile and adult African grasscutters were 0.33 g ± 0.01 g, 0.47 g ± 0.01 g and 0.93 g ± 0.02 g, respectively. The increase from neonate to juvenile (p = 0.002) and adult (p = 0.003) was significant. The pons lengths in the neonate, juvenile and adult were 2.05 mm ± 0.05 mm, 3.86 mm ± 0.05 mm and 4.16 mm ± 0.22 mm, respectively. There was a significant increase in the length of the pons from the neonate to the juvenile (p = 0.002), but the increase from the juvenile to the adult period was not significant (p = 0.263). There was also a significant (p 0.05) increase in the weights and lengths of the medulla oblongata from neonate to juvenile and adult periods. In adults, the nose-rump length and the length of the medulla were significantly negatively correlated (r² = 0.47; p = 0.043). The present study concluded that the postnatal development of some brainstem structures in the African grasscutter varies with age.
Electronic Health Record Alert-Related Workload as a Predictor of Burnout in Primary Care Providers
Authors: Russo Elise , Singh Hardeep , Gregory Megan E.
Published: July 2017

Background: Electronic health records (EHRs) have been shown to increase physician workload. One EHR feature that contributes to increased workload is asynchronous alerts (also known as inbox notifications) related to test results, referral responses, medication refill requests, and messages from physicians and other health care professionals. This alert-related workload results in negative cognitive outcomes, but its effect on affective outcomes, such as burnout, has been under-studied.

Objectives: To examine EHR alert-related workload (both objective and subjective) as a predictor of burnout in primary care providers (PCPs), in order to ultimately inform interventions aimed at reducing burnout due to alert workload.

Methods: A cross-sectional questionnaire and focus group of 16 PCPs at a large medical center in the southern United States.

Results: Subjective, but not objective, alert workload was related to two of the three dimensions of burnout, including physical fatigue (p = 0.02) and cognitive weariness (p = 0.04), when controlling for organizational tenure. To reduce alert workload and subsequent burnout, participants indicated a desire to have protected time for alert management, fewer unnecessary alerts, and improvements to the EHR system.

Conclusions: Burnout associated with alert workload may be in part due to subjective differences at an individual level, and not solely a function of the objective work environment. This suggests the need for both individual and organizational-level interventions to improve alert workload and subsequent burnout. Additional research should confirm these findings in larger, more representative samples.

Authors: Sachdeva Kavita , Naskar Saurav
Published: July 2017

Aim

The aim of this study was to evaluate all the cases of sinonasal masses based on histopathology into neoplastic and non-neoplastic lesions and to study their clinical and radiological presentations.

Materials and methods

The present study was carried out in 42 patients coming to the outpatient and inpatient Department of ENT of Netaji Subhash Chandra Bose Medical College & Hospital with the complaint of nasal obstruction during the period of March 2015 to August 2016. Patients were subjected to thorough clinical examinations and radiological investigations, which included digital X-ray paranasal sinus (PNS) and contrast-enhanced computed tomography PNS, and diagnosis was confirmed by nasal biopsy for histopathology reports.

Results and observations

A total of 42 patients were studied, of which 71.43% were non-neoplastic and 28.57% were neoplastic. Nasal polyps were the commonest non-neoplastic lesions (61.91%). Most common benign neoplastic lesion was angiofibroma (11.9%), while the commonest malignant neoplastic mass was found to be squamous cell carcinoma (7.14%). There was one case of adenoid cystic carcinoma.

Conclusion

Patients with sinonasal masses may present with trivial complaints, but proper evaluation of all the cases will enable us to make specific diagnosis and treat them accordingly.

Authors: Mogarnad Mohan , Mohta Vandana
Published: July 2017

Aim

To study the clinical profile of deviated nasal septum and to assess the subjective efficacy of the surgical outcome using Likert scale.

Materials and methods

This study is a prospective, observational, single-center study from October 2013 to May 2015. The study was conducted in Sri Siddhartha Medical College, Tumkur, Karnataka, India. A detailed clinical history was taken and clinical examination of the patient was carried out. Sixty symptomatic patients were taken up. Patient scored their symptom-related severity using a Likert scale preoperatively. All patients underwent conventional septoplasty. Postoperatively, their symptoms were scored on 30th, 45th, and 90th day.

Results

Preoperative and Postoperative values were analyzed. Statistically significant improvement was observed in the entire population: Nasal obstruction (p<0.001), headache (p<0.001), nasal discharge (p<0.001), facial pain (p<0.001), and hyposmia (p<0.001). Patient satisfaction was high and they used fewer nasal medications.

Conclusion

After surgical correction of the septum and analysis of the subjective scale, i.e., Likert scale showed improvement in all symptoms. The principal benefits of septal surgery relate to improvement in nasal symptoms.

Histopathological Profile of Nasal Cavity, Paranasal Sinuses, and Nasopharyngeal Masses in Hill State of Himachal Pradesh, India
Authors: Guleria Trilok C , Mohindroo Shobha , Mohindroo Narender K
Published: July 2017

Introduction:

Nasal masses are common finding in the ear, nose, and throat outpatient department. Most patients present with complaints of nasal obstruction. A sinonasal mass can have various differential diagnoses. They may be congenital, inflammatory, neoplastic (benign or malignant), or traumatic in nature. A careful histopathological examination is necessary to decide the nature of any particular lesion.

Materials and methods:

The retrospective study was carried out between January 2011 and December 2013. A total of 185 cases diagnosed with masses of the nasal cavity, paranasal sinuses, and nasopharynx were included. Data from histopathological records were retrieved to confirm the diagnosis.

Observations:

Among 185 cases, 75% were non-neoplastic and 25% were neoplastic. Among neoplastic masses, 57% were benign and 43% were malignant. The age of presentation ranged from first to eighth decade of life (mean age 37.74 years). The lesions had a stronger predilection for males (1.68:1). Among non-neoplastic lesions, nasal polyp was the commonest lesion followed by ethmoidal mucocele (1.44%) and lupus vulgaris (0.72%). Among benign lesions, inverted papilloma (30.77%) and nasopharyngeal angiofibroma (30.77%) were the commonest followed by capillary hemangioma (15.38%), osteoma (7.68%), nasopharyngeal lymphoepithelioma (3.85%), chondroma (3.85%), pleomorphic adenoma (3.85%), and schwannoma (3.85%). Squamous cell carcinoma (40%) was the commonest malignant neoplastic lesion observed followed by adenoid cystic carcinoma (20%), malignant melanoma (15%), nasopharyngeal carcinoma (10%), esthesioneuroblastoma (10%), and non-Hodgkin lymphoma (5%).

Conclusion:

Among the noninflammatory lesion, nasal polyp is the commonest lesion. Nasal polyps are more common in hilly area may be due to exposure to pine pollens. There is no difference in the histopathological profile of benign and malignant lesions.

Comparative Evaluation of Antimicrobial Efficacy of Neem, Miswak, Propolis, and Sodium Hypochlorite against Enterococcus faecalis using EndoVac
Authors: Daga Priya , Asrani Hemant , Farista Shanin , Mishra Praveen
Published: July 2017

Aim

To compare the antimicrobial efficacy of herbal irrigants neem, miswak, propolis with sodium hypochlorite using conventional needle irrigation and EndoVac irrigation system against Enterococcus faecalis.

Materials and methods

A total of 120 extracted single-rooted mandibular premolar teeth were infected for 21 days with E. faecalis after instrumentation with ProTaper system. Before irrigation procedure, dentinal shavings were collected in 1 mL of sterile broth and incubated. The optical density of each broth was measured using digital colorimeter and initial readings were recorded. Samples were then divided into four groups of 30 teeth each – Group I: Sodium hypochlorite irrigation, group II: Neem irrigation, group III: Miswak irrigation, group IV: propolis irrigation. Each group was further divided into two subgroups – (a) EndoVac irrigation (b) conventional needle irrigation. After irrigation, dentinal shavings were collected and optical density recorded. The values were analyzed statistically with Student's t test and analysis of variance followed by Tukey's honest significant difference test; p-value < 0.05 was considered to be statistically significant.

Results

The postirrigation optical densities in all the groups were significantly lower than preirrigation values. Sodium hypochlorite demonstrated better antimicrobial efficacy followed by propolis, neem, and miswak. Differences in optical density values for all irrigants are higher in EndoVac (p < 0.0001) compared with needle (p = 0.0009) group, but it failed to reach statistical significance.

Conclusion

Sodium hypochlorite proved to be a better irrigant followed by propolis, neem, and miswak. EndoVac irrigation system was more effective for elimination of E. faecalis than needle irrigation group.

Rehabilitation of a Patient with Completely Edentulous Maxillary Arch using “All on 4” Concept of Implantation
Authors: Harshakumar K , Abraham Nimisha B , Lylajam S , Prasanth V
Published: July 2017

Treatment options for insufficient ridge morphology includes the use of short implants, vertical ridge augmentation procedures, or cantilever prostheses in completely edentulous patients. Due to the less predictable long-term prognosis associated with the above-mentioned procedures, the “All on 4” technique was proposed for the rehabilitation in edentulous jaws. The All on 4 treatment concept meets the patient requirements with an immediately loaded fixed prosthesis supported by four implants. This article depicts a clinical report in which an “All on 4” implant treatment is done with delayed loading protocol due to inadequate primary stability obtained.

Prosthetic Rehabilitation of Velopharyngeal Incompetence
Authors: Dhawan Pankaj , Madhukar Pankaj , Tandan Piyush , Agarwal Pratik
Published: July 2017

Velopharyngeal (VP) dysfunction takes place when palatopharyngeal valve is unable to perform its own closing due to a lack of tissue or lack of proper movement. Insufficiency induces nasal regurgitation of liquids, hypernasal speech, nasal escape, disarticulations, and impaired speech intelligibility. Treatment options include surgical correction, prosthetic rehabilitation, and speech therapy, though optimal results often require a multidisciplinary approach. This case report describes a novel approach for rehabilitation of a patient with soft palate defect (VP incompetence).

The boundary condition for vertical velocity and its interdependence with surface gas exchange
Authors: Kowalski Andrew S.
Published: July 2017

Abstract. The law of conservation of linear momentum is applied to surface gas exchanges, employing scale analysis to diagnose the vertical velocity (w) in the boundary layer. Net upward momentum in the surface layer is forced by evaporation (E) and defines non-zero vertical motion, with a magnitude defined by the ratio of E to the air density, as w = E/ρ. This is true even right down at the surface where the boundary condition is w|0 = E/ρ|0 (where w|0 and ρ|0 represent the vertical velocity and density of air at the surface). This Stefan flow velocity implies upward transport of a non-diffusive nature that is a general feature of the troposphere but is of particular importance at the surface, where it assists molecular diffusion with upward gas migration (of H2O, for example) but opposes that of downward-diffusing species like CO2 during daytime. The definition of flux–gradient relationships (eddy diffusivities) requires rectification to exclude non-diffusive transport, which does not depend on scalar gradients. At the microscopic scale, the role of non-diffusive transport in the process of evaporation from inside a narrow tube – with vapour transport into an overlying, horizontal airstream – was described long ago in classical mechanics and is routinely accounted for by chemical engineers, but has been neglected by scientists studying stomatal conductance. Correctly accounting for non-diffusive transport through stomata, which can appreciably reduce net CO2 transport and marginally boost that of water vapour, should improve characterisations of ecosystem and plant functioning.
MLS measurements of stratospheric hydrogen cyanide during the
2015–16 El Niño event
Authors: Pumphrey Hugh C. , Glatthor Norbert , Bernath Peter F. , Boone Christopher D. , Hannigan James , Ortega Ivan , Livesey Nathaniel J. , Read William G.
Published: July 2017

Abstract. It is known from ground-based measurements made during the 1982–83 and 1997–98 El Niño events that atmospheric HCN tends to be higher than usual during such years. The Microwave Limb Sounder (MLS) on Aura has been measuring HCN mixing ratios since launch in 2004; the measurements are ongoing at the time of writing. The winter of 2015–16 has seen the largest El Niño event since 1997–98. We present MLS measurements of HCN in the lower stratosphere for the Aura mission to date, comparing the 2015–16 El Niño period to the rest of the mission. HCN in 2015–16 is higher than at any other time during the mission, but ground based measurements suggest that it may have been even more elevated in 1997–98. As the MLS HCN data are essentially un-validated, we show them alongside data from the MIPAS and ACE-FTS instruments; the three instruments agree reasonably well in the tropical lower stratosphere. Global HCN emissions calculated from the GFED (V4.1) database are very much greater during large El Niño events and are greater in 1997–98 than in 2015–16, thereby showing good qualitative agreement with the measurements. Correlation between ENSO indices, measured HCN and GFED HCN emissions is less clear away from the 2015–16 event. In particular, the 2009–10 winter had fairly strong El Niño conditions and fairly large GFED HCN emissions, but very little effect is observed in the MLS HCN.
A global perspective on atmospheric blocking using GPS radio occultation – one decade of observations
Authors: Brunner Lukas , Steiner Andrea K.
Published: July 2017

Abstract. Atmospheric blocking represents a weather pattern where a stationary high-pressure system weakens or reverses the climatological westerly flow at mid-latitudes for up to several weeks. It is closely connected to strong anomalies in key atmospheric variables such as geopotential height, temperature, and humidity. Here we provide, for the first time, a comprehensive, global perspective on atmospheric blocking and related impacts by using an observation-based data set from Global Positioning System (GPS) radio occultation (RO) from 2006 to 2016. The main blocking regions in both hemispheres and seasonal variations are found to be well-represented in RO data. The effect of blocking on vertically resolved temperature and humidity anomalies in the troposphere and lower stratosphere is investigated for blocking regions in the northern and southern hemisphere, respectively. We find a statistically significant correlation of blocking with positive temperature anomalies, exceeding 3 K in the troposphere and a reversal above the tropopause with negative temperature anomalies below -3 K in the lower stratosphere. Specific humidity is positively correlated with temperature throughout the troposphere with larger anomalies revealed in the southern hemisphere. At the eastern and equator-ward side of the investigated blocking regions, a band of tropospheric cold anomalies reveals advection of cold air by anti-cyclonic motion around blocking highs, which is less distinct in the southern hemisphere due to stronger zonal flow. We find GPS RO a promising new data set for blocking research giving insight into the vertical atmospheric structure, especially in light of the expected increase in data coverage that future missions will provide.
Biogenic sediments from coastal ecosystems to beach–dune systems: implications for the adaptation of mixed and carbonate beaches to future sea level rise
Authors: De Falco Giovanni , Molinaroli Emanuela , Conforti Alessandro , Simeone Simone , Tonielli Renato
Published: July 2017

Abstract. Coastal ecosystems produce and store carbonate particles, which play a significant role in the carbonate dynamics of coastal areas and may contribute to the sediment budget of adjacent beaches. In the nearshore seabed of temperate zones (e.g. Mediterranean Sea and South Australia), marine biogenic carbonates are mainly produced inside seagrass meadows. This study quantifies the contribution of biogenic sediments, mainly produced in Posidonia oceanica seagrass meadows and secondarily in photophilic algal communities, to the sediment budget of a Mediterranean beach–dune system (San Giovanni beach, western Sardinia, western Mediterranean Sea). A set of geophysical, petrographic and sedimentological data was used to estimate the sediment volume and composition of the beach–dune system as a whole. The San Giovanni beach–dune system contains 3 797 000 ± 404 000 t of sediment, 83 % (3 137 000 ± 404 000 t) of which is located in the coastal wedge, 16 % (619 000 ± 88 000 t) in the dune fields and 1 % (41 000 ± 15 000 t) in the subaerial beach. The sediments are composed of mixed modern bioclastic and relict bioclastic and non-bioclastic grains from various sources. The system receives a large input of modern bioclastic grains, mainly composed of rhodophytes, molluscs and bryozoans, which derive from sediment production of present-day carbonate factories, particularly P. oceanica seagrass meadows. Radiocarbon dating of modern bioclastic grains indicated that they were produced during the last 4.37 kyr. This value was used to estimate the long-term deposition rates of modern bioclastic sediments in the various beach compartments. The total deposition rate of modern bioclastic grains is 46 000 ± 5000 t century−1, mainly deposited in the coastal wedge (39 000 ± 4 000 t century−1) and dunes (7000 ± 1000 t century−1), and 46 000 t represents  ∼  1.2 % of the total beach–dune sediment mass. Carbonate production from coastal ecosystems was estimated to be 132 000∕307 000 t century−1, 28 % (15 % ∕ 34 %) of which is transported to the beach–dune system, thus significantly contributing to the beach sediment budget. The contribution to the beach sediment budget represents a further ecosystem service, which our data can help quantify, provided by P. oceanica. The value of this sediment-supply service is in addition to the other important ecological services provided by seagrass meadows. The dependence of the beach sediment budget on carbonate production associated with coastal ecosystems has several implications for the adaptation of mixed and carbonate beaches to the loss of seagrass meadows due to local impacts and the changes expected to occur over the next few decades in coastal ecosystems following sea level rise.

Abstract. Since June 2012 the Saint Petersburg magnetic observatory is being developed and maintained by two institutions of the Russian Academy of Sciences (RAS) – the Geophysical Center of RAS (GC RAS) and the Saint Petersburg branch of the Pushkov Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation of RAS (IZMIRAN SPb Branch). On 29 April 2016 the application from the Saint Petersburg observatory (IAGA code SPG) for introduction into the INTERMAGNET network was accepted after approval by the experts of the first definitive data set over 2015, produced by the GC RAS, and on 9 June 2016 the SPG observatory was officially certified. One of the oldest series of magnetic observations originated in 1834 was resumed in the 21st century, meeting the highest quality standards and all modern technical requirements. In this paper a brief historical and scientific background of the SPG observatory foundation and development is given, the stages of its renovation and upgrade in the 21st century are described, and information on its current state is provided. The first results of the observatory functioning are discussed, geomagnetic variations registered at the SPG observatory are assessed and compared with geomagnetic data from the INTERMAGNET observatories, located in the same region.

Abstract. In this study, we show that land subsidence in Quetta valley, Pakistan is caused by exploitation of groundwater based on the analysis of European Space Agency (ESA) Sentinel satellite data. For this, we performed interferometry analysis using twenty nine Sentinel-1 SAR images to obtain twenty eight interferograms of land subsidence for the period between 16 Oct 2014 and 06 Oct 2016. Then, the land subsidence was compared with the land cover of the study area that was derived from Sentienl-2 multispectral images. The results reveal that, for the period of two years, the entire study area experienced highly uneven land subsidence with its magnitude ranging between 10 mm to 280 mm. The spatial pattern of land subsidence showed a high correlation with that of land covers. While urban and cultivated area with high groundwater extraction showed great amount of land subsidence, barren and seasonally cultivated area did not show as much land subsidence.

Published: July 2017

The Journal of Learning Design is about to close. Our last issue was Volume 10 (2) released in March 2017.

In closing and saying farewell, we would like to sincerely thank those who have written, reviewed, read and referenced the articles we have published in our 27 issues (10 volumes). Thanks must also go to the Queensland University of Technology for encouraging and supporting the journal, particularly since our move to an OJS platform.

The Journal has built a reputation for quality and diversity of approach – we have covered a wide range of disciplines and learning technologies in accessible ways. We have supported the cause of Open Access publishing and shown how being ‘open’ and ‘free’ need not compromise rigour. We have supported the cause of online publishing and shown it to be a viable alternative that does not take advantage of anyone or treat creative output as a commercial commodity.

Above all, we have collectively supported the promotion of the scholarship of teaching and learning in higher education. We believe we have also filled an important role to support early career academics and emerging researchers. We have learnt a great deal as editors and are grateful for the opportunities the journal has presented to us both personally and professionally.

There is no sadness in closing the journal. It is simply time to say Goodbye with good grace and in the knowledge of a job well done. Thank you to all.

Treatment with Erythropoiesis Stimulating Agents in Patients with Chronic Kidney Disease Complicated by Cancer
Authors: Wanchoo Rimda , Jhaveri Kenar D. , Fishbane Steven
Published: July 2017

Anemia, commonly seen in patients with chronic kidney disease (CKD), is due to a relatively reduced production of erythropoietin by renal interstitial fibroblasts. The development of cancer in patients with kidney disease puts them at a higher risk of developing severe anemia along with its antecedent problems. The treatment of anemia in patients with cancer has changed substantially in recent years. This is partly due to results from a large number of published studies that indicate an increased risk of mortality and tumor progression with erythropoiesis-stimulating agents (ESA) therapy, which may have been overstated, on careful review of the literature. In the nephrology literature, studies exploring the normalization of hemoglobin with erythropoietin treatment have found increased cardiovascular and thromboembolic events, and risk of death. Many CKD and dialysis patients receive ESA to maintain a hemoglobin goal in the range of 9-11.5 g/dL. In patients with kidney disease, a cancer diagnosis makes the treatment of anemia challenging. In this review, we discuss the pathobiology of anemia in kidney disease, the benefits and risks of ESA treatment in CKD patients with cancer, and provide recommendations on ESA treatment for clinicians taking care of this unique subset of patients.
Growth of the Kidney–Cancer Connection
Authors: Perazella Mark A.
Published: July 2017

The fast-paced growth of Onco-Nephrology reflects the unique connection that exists for kidney disease and cancer in clinical medicine. This area of sub-specialization combines the knowledge and skills of a number of specialty groups that span all corners of medicine. Nephrologists, oncologists, urologists, intensivists, pharmacologists, and palliative care specialists are all important players in this arena. In this issue of the Journal of Onco-Nephrology, a series of papers addressing the various forms of kidney disease that develop in patients with cancer is presented as part of the Onco-Nephrology Highlights section. These papers are based on the Onco-Nephrology Symposium that took place at the MD Anderson Cancer Center in Houston, Texas, USA. I hope you find these 4 papers educational and practical in your provision of care to patients with cancer and kidney disease.
Denosumab: Renal Safety Evaluation
Authors: Malberti Fabio , Foramitti Marina
Published: July 2017

Denosumab, a fully human monoclonal antibody against the receptor activator of nuclear factor kappa B ligand (RANKL), has been approved for the prevention of skeletal-related events in metastatic solid tumor patients with bone metastases. As opposed to the bisphosphonates, denosumab is not excreted by the kidney, and renal function does not have a significant effect on denosumab pharmacokinetics or pharmacodynamics. Thus, dose adjustment is not required in patients with renal insufficiency. In contrast to the bisphosphonates, denosumab has not been documented to have nephrotoxic effects. However, it does share some toxicities with bisphosphonates, including hypocalcemia and osteonecrosis of the jaw. In this review, the warnings and recommendations for the use of denosumab in patients with renal insufficiency are discussed.
High Cut-Off Hemodialysis for Myeloma Cast Nephropathy – Do We Finally Have An Answer?
Authors: Finkel Kevin , Fabbrini Paolo
Published: July 2017

The most common kidney presentation in patients with multiple myeloma (MM) is acute kidney injury (AKI) from cast nephropathy. Patients have a poorer 1 year survival compared to patients free of kidney involvement. The key to treating cast nephropathy is rapid reduction of free light chain (FLC) levels. The modern era of MM treatment was ushered in by the introduction of newer chemotherapeutic agents, such as bortezomib. Also, there is interest in the application of extracorporeal removal of FLCs with high cut-off hemodialysis (HCO-HD) using a dialysis membrane with a higher molecular weight cut-off pore size compared to conventional high-flux (HF) dialyzers. Does the use of HCO-HD provide additional benefit to bortezomib-based chemotherapy alone? Two trials have now been completed and the results were published in abstract form and orally presented at the 2016 American Society Nephrology Annual Scientific Meeting in Chicago, Illinois, USA. Both the MYRE and the EuLITE trials randomized patients with dialysis-dependent AKI due to biopsy-confirmed cast nephropathy to bortezomib-based chemotherapy, and either conventional high-flux hemodialysis (HF-HD) or HCO-HD with a primary end point of the discontinuation of renal replacement therapy. In the MYRE study, more patients in the HCO-HD arm were independent of dialysis at 6 months. In the EuLITE study, there was no difference in kidney recovery at 3 months. Both studies were small, which makes any firm conclusions on the benefit of HCO-HD tenuous. Based on the current knowledge, without more robust data, the routine use of HCO-HD cannot be recommended.

Aim

Immune checkpoint inhibitors of programmed death-1 (PD-1)/programmed death-ligand 1 (PD-L1) have recently entered in the therapeutic armamentarium of several types of cancer. Besides the survival benefit, the true revolution of these agents is the distinctive toxicity profile. We aim to assess the incidence and relative risk (RR) of renal toxicity (RT) in patients with solid tumors treated with monoclonal antibodies (mAbs) directed against PD-1/PD-L1.

Methods

By searching the MEDLINE/PubMed, Cochrane Library, and ASCO Meeting abstracts, prospective studies were identified. Combined RRs and 95% confidence intervals (CIs) were calculated using fixed- or random-effects methods.

Results

Eleven articles were selected for this analysis, with a total of 5,722 patients who were used to evaluate RT. The incidence of anti-PD-1-related RT of all-grades and high-grades was low (1.4% and 0.2%, respectively). However, compared to controls, treatment with PD-1 inhibitors was associated with a significant increased risk of any grade RT (RR = 1.85, 95% CI, 1.07-3.20; p = 0.03) but not high-grade RT (RR = 1.57, 95% CI, 0.56-4.36; p = 0.39). Pembrolizumab significantly increased the risk of any-grade RT (RR = 4.91, p = 0.01) compared to the control arm, and a significant difference was found between nivolumab and pembrolizumab for developing RT of any grade (p = 0.04). Conversely, no differences were identified between the type of prior treatment (prior platinum-containing chemotherapy regimen vs. nonplatinum containing regimen).

Conclusions

Immune-mediated RT is a rare adverse event that is generally low in severity. Compared to standard therapies, anti-PD-1 mAbs significantly increase the risk of any grade, without conditioning the risk of high-grade RT. The type of PD-1 inhibitor could affect the risk of developing any-grade RT, while prior therapy with platinum-containing regimens does not affect the risk of developing RT.
