Abstract. The main advancements of the Beijing Climate Center (BCC) climate system model from
phase 5 of the Coupled Model Intercomparison Project (CMIP5) to phase
6 (CMIP6) are presented, in terms of physical parameterizations and model
performance. BCC-CSM1.1 and BCC-CSM1.1m are the two models involved in CMIP5,
whereas BCC-CSM2-MR, BCC-CSM2-HR, and BCC-ESM1.0 are the three models configured for
CMIP6. Historical simulations from 1851 to 2014 from BCC-CSM2-MR (CMIP6) and
from 1851 to 2005 from BCC-CSM1.1m (CMIP5) are used for models assessment.
The evaluation matrices include the following: (a) the energy budget at
top-of-atmosphere; (b) surface air temperature, precipitation, and atmospheric circulation for
the global and East Asia regions; (c) the sea surface temperature (SST) in the
tropical Pacific; (d) sea-ice extent and thickness and Atlantic Meridional
Overturning Circulation (AMOC); and (e) climate variations at different timescales, such as the global warming trend in the 20th century, the stratospheric
quasi-biennial oscillation (QBO), the Madden–Julian Oscillation (MJO), and the diurnal
cycle of precipitation. Compared with BCC-CSM1.1m, BCC-CSM2-MR shows
significant improvements in many aspects including the tropospheric air
temperature and circulation at global and regional scales in East Asia and
climate variability at different timescales, such as the QBO, the MJO, the diurnal cycle
of precipitation, interannual variations of SST in the equatorial Pacific,
and the long-term trend of surface air temperature.

Published: April 2019

Abstract. Groundwater plays a significant role in glacial hydrology and can buffer changes to the timing and magnitude of meltwater flows. However, proglacial aquifer characteristics or groundwater dynamics in glacial catchments are rarely studied directly. We provide direct evidence of proglacial groundwater storage, and quantify multi-year groundwater-meltwater dynamics, through intensive and high resolution monitoring of the proglacial system of a rapidly retreating glacier, Virkisjökull, in SE Iceland. Proglacial unconsolidated glaciofluvial sediments comprise a highly permeable aquifer in which groundwater flow in the shallowest 20–40 m of the aquifer is equivalent to 4.5 % (2.6–5.8 %) of mean annual meltwater river flow, and 9.7 % (5.8–12.3 %) of winter flow. Groundwater flow through the entire aquifer thickness represents 9.8 % (3.6–21 %) of annual meltwater flow. Groundwater in the aquifer is actively recharged by local precipitation, both rainfall and snowmelt, and strongly influenced by individual precipitation events. Significant glacial meltwater influence on groundwater within the aquifer occurs in a 50–500 m river zone within which there are complex groundwater / meltwater exchanges. Stable isotopes, groundwater dynamics and temperature data demonstrate active recharge from river losses, especially in the summer melt season, with more than 25 % of groundwater in this part of the aquifer sourced from meltwater. Such proglacial aquifers are common globally, and future changes in glacier coverage and precipitation are likely to increase the significance of groundwater storage within them. The scale of proglacial groundwater flow and storage has important implications for measuring meltwater flux, for predicting future river flows, and for providing strategic water supplies in de-glaciating catchments.
Challenges associated with the climatic interpretation of water stable isotope records from a highly resolved firn core from Adélie Land, coastal Antarctica

Published: April 2019

Abstract. A new 21.3 m firn core was drilled in 2015 at a coastal Antarctic
high-accumulation site in Adélie Land (66.78∘ S; 139.56∘ E,
602 m a.s.l.), named Terre Adélie 192A (TA192A). The mean isotopic values (-19.3‰±3.1 ‰ for
δ18O and 5.4 ‰±2.2 ‰ for deuterium
excess) are consistent with other coastal Antarctic values. No significant
isotope–temperature relationship can be evidenced at any timescale. This
rules out a simple interpretation in terms of local temperature. An
observed asymmetry in the δ18O seasonal cycle may be explained
by the precipitation of air masses coming from the eastern and western
sectors in autumn and winter, recorded in the d-excess signal showing
outstanding values in austral spring versus autumn. Significant positive
trends are observed in the annual d-excess record and local sea ice extent
(135–145∘ E) over the period 1998–2014. However, process studies focusing on resulting isotopic compositions and
particularly the deuterium excess–δ18O relationship, evidenced
as a potential fingerprint of moisture origins, as well as the collection of
more isotopic measurements in Adélie Land are needed for an accurate
interpretation of our signals.
Uncertainty quantification of the multi-centennial response of the Antarctic ice sheet to climate change
Authors: Bulthuis Kevin , Arnst Maarten , Sun Sainan , Pattyn Frank
Published: April 2019

Abstract. Ice loss from the Antarctic ice sheet (AIS) is expected to become
the major contributor to sea level in the next centuries. Projections of the
AIS response to climate change based on numerical ice-sheet models remain
challenging due to the complexity of physical processes involved in ice-sheet
dynamics, including instability mechanisms that can destabilise marine basins
with retrograde slopes. Moreover, uncertainties in ice-sheet models limit the
ability to provide accurate sea-level rise projections. Here, we apply
probabilistic methods to a hybrid ice-sheet model to investigate the
influence of several sources of uncertainty, namely sources of uncertainty in
atmospheric forcing, basal sliding, grounding-line flux parameterisation,
calving, sub-shelf melting, ice-shelf rheology and bedrock relaxation, on the
continental response of the Antarctic ice sheet to climate change over the
next millennium. We provide probabilistic projections of sea-level rise and
grounding-line retreat, and we carry out stochastic sensitivity analysis to
determine the most influential sources of uncertainty. We find that all
investigated sources of uncertainty, except bedrock relaxation time,
contribute to the uncertainty in the projections. We show that the
sensitivity of the projections to uncertainties increases and the
contribution of the uncertainty in sub-shelf melting to the uncertainty in
the projections becomes more and more dominant as atmospheric and oceanic
temperatures rise, with a contribution to the uncertainty in sea-level rise
projections that goes from 5 % to 25 % in RCP 2.6 to more than 90 % in
RCP 8.5. We show that the significance of the AIS contribution to sea level
is controlled by the marine ice-sheet instability (MISI) in marine basins,
with the biggest contribution stemming from the more vulnerable West
Antarctic ice sheet. We find that, irrespective of parametric uncertainty,
the strongly mitigated RCP 2.6 scenario prevents the collapse of the West
Antarctic ice sheet, that in both the RCP 4.5 and RCP 6.0 scenarios the
occurrence of MISI in marine basins is more sensitive to parametric
uncertainty, and that, almost irrespective of parametric uncertainty, RCP 8.5
triggers the collapse of the West Antarctic ice sheet.

Published: April 2019

Objectives: This paper describes the findings from interviews, presented as the second stage of a study aimed at developing a career pathway for community nursing and midwifery for one Australian state, with a particular focus on early transition to community-based practice.Background: With the increasing incidence of chronic conditions, health services are focused on primary and community care as the central point of care provision, and with it, the realisation that nurses have a central role to play in care delivery. Yet, community nursing is a poorly defined area of practice, and it is often seen as an unattractive career option.Methods: Semi-structured interviews were conducted with seven experienced registered nurses currently employed and working in the community. Data analysis was undertaken using a pragmatic approach that allowed for the examination of themes emerging from the participant narratives. One member of the research team conducted interviews, with cross-checking of transcripts undertaken by other members of the team. Narrative was drawn from the transcripts and aligned to themes emerging from a draft pathway informed by a systematic review. COREQ checklist was adhered.Results: Participants identified elements essential to a good transition that included responsive orientation, innovative leadership and the development of community-based networks related to social, legal, financial and practical elements of care. Experiential knowledge and a sense of belonging within the community were two important factors considered essential to successful transition.Conclusion: Community nursing is a specialised practice which requires a revision of expectations, preparation for practice and acknowledgement of its value, before nurses can become responsive to the changing community emphasis on health service delivery.Potential implications: For a career pathway to accommodate early transition into community practice, key issues need to be addressed in relation to educational preparation, support for practice, and acceptance.

Does Technology Matter When Selecting a Target Firm in an M&A? Some Evidence on a European M&A Sample
Authors: Fidanza Barbara
Published: April 2019

Using a sample of European M&As from 2009 to 2017, this work assesses whether there is a linkage between a firm's innovation orientation and its participation in an M&A. This main aim has been divided into three aims: defining the target firms’ characteristics in M&A deals with a special focus on innovation orientation, performance, financial structure and size; understanding what kind of firm is generally acquired from institutional investors; describing the effects of M&A deals on the targets. With reference to the analysis method, aims were pursued through logistic regressions on the cross-sectional sample and by comparing pre-deal and post-deal average balance values.

The result is twofold. First, a high probability of being targeted is associated with high portfolio patents and low research and development costs of a firm, but only in cases of technological overlap; otherwise the R&D intensity, performance and size of firms are relevant. Second, when analysing the effects of M&As, comparing the same variables in post vs. pre deal period, they are only significant for patent and R&D costs. These results confirm that the M&A transactions produce useful synergy in terms of innovation capability.

The attitudes of prisoners towards participation in restorative justice procedures

Restorative justice can be implemented at different stages of criminal proceedings. In Israel, restorative justice processes are mainly used prior to sentencing, while there are no restorative programmes for adults following sentencing and while serving their prison sentences. The aim of the present study is to examine the possibility of implementing restorative processes within prison walls. To this end, the present study empirically investigates the level of readiness and willingness of prisoners (n = 110) from two large prisons in Israel to participate in restorative processes and examines the psychological mechanisms underlying their attitudes towards actual participation in these processes. The study proposes a model according to which the relationship between the cognitive component of attitude towards victims and the harm caused by the offence (beliefs and thoughts) and the behavioural component of attitude (the inclination to participate in restorative processes) is mediated by the affective component of attitude towards the offence (sense of guilt and shame). The findings of the study support the proposed model. The study also found that the more prisoners perceived the harm they caused as having more dimensions (physical, economic, emotional), the more positive their attitudes towards restorative justice would be. This study will advance research into restorative justice at a stage that has not previously been researched in Israel and has rarely been investigated elsewhere.
Exploring the intertwining between human rights and restorative justice in private cross-border disputes

Exploring the intertwining between human rights and restorative justice in private cross-border disputes

International human rights instruments operate on the assumption that states are the focal human rights duty bearers. However, private actors can harm human rights as well. Moreover, since mechanisms at a supranational level are lacking, these instruments rely primarily on states for their enforcement. Yet states’ internal rules and courts are meant to address infringements that are confined within their borders, and are therefore often structurally unable to deal with violations having transnational impact. Restorative justice has proven to respond in depth to different kinds of wrongdoing and, although addressing the peculiarities of each case, restorative procedures can systemically prevent deviant behaviour as well. Additionally, as restorative justice relies on voluntary participation it need not operate in a specific territory. Having this broader picture in mind, the article explores whether restorative justice might be adequate for dealing with human rights infringements perpetrated by private actors that have cross-border impact.

From the 16th to 18th centuries in Western Europe care and nursing institutions for the sick were created by the faithful of the Catholic Church. The greatest successes in that field were achieved by three persons: Juan de Dios, Camillo de Lellis and Vincent de Paul. They established charity, care and nursing congregations, orders and convents which conducted wide charity activities in Europe before the French Revolution.
The development of nursing care of the sick in Western Europe in the 18th and the first half of the 19th centuries
Authors: Supady Jerzy
Published: April 2019

The Enlightenment ideology and the French Revolution had a very negative impact on the activities of religious congregations in respect of nursing care of the sick in hospitals in the 18th century. Emperor Napoleon I attempted to improve the existing situation by restoring the right for nursing care to nuns. In the first half of the 19th century, in Germany catholic religious orders had the obligation to provide nursing care and in the 30’s of the 19th century the Evangelical Church also joined charity work in hospitals by employing laywomen, i.e. deaconesses.

Authors: Bibro Marta , Jankowicz-Szymańska Agnieszka , Wódka Katarzyna , Łaczek-Wójtowicz Małgorzata
Published: April 2019

Background: In the population of people with intellectual disabilities (ID) there is a frequent occurrence of bone deformities and orthopedic problems affecting the feet as well. They are associated with a change of the loading of the feet. It affects the deterioration of the functional efficiency of the feet, often contributes to discomfort, pain and predisposes to the development of adverse changes in the upper body segments. The aim of the study was to assess the impact of intellectual disability in participants with aetiology other than Down’s syndrome on longitudinal arching and symmetry of lateral and medial load of the foot.
Materials and methods: There were 38 participants with mild and moderate intellectual disability, with an average age of 23 years and 44 young non-disabled people with an average age of 20.8 under research. The main measurement tool used to assess the arching and loading the foot zones was the BTS P-WALK platform. The measurement included analysis in terms of statics and lasted 30s.
Results: The comparison of both groups showed no significant differentiation in the medial and lateral load of the forefoot and rearfoot. Among people with ID correct arches of the feet were observed in 52.6% of participants in the right foot and 57.9% of the left foot, while in the control group in 56.9% in both the right and left foot. People with intellectual disabilities were characterized by a higher rate of flatfoot in relation to the control group. The hollow foot was more frequently observed in control group than in people with ID.
Conclusions: In people with intellectual disabilities with aetiology other than Down’s syndrome, flat feet are diagnosed more often than in healthy peers who do not differ in body weight and BMI. Intellectual disability is associated with a greater loading of the medial part of the forefoot.

Welfare (not) welcomed. A few words about NIMBY for social workers
Authors: Szrejder Dariusz
Published: April 2019

The article deals with an issue of social consent for institutional social help activities in the functional area of the local community. When planning the development of social infrastruc-ture for social help purposes, it sometimes happens that some elements are not taken into ac-count such as the consent of town residents (neighbours) to the location of the infrastructure. Plans to create a social facility encounter resistance of residents who are concerned about their own safety. The source of such anxiety are clients of institutions, for whom the inhabitants have negative stereotypes. We experience then a conflict situation, social protests, referred to in the scientific literature as the NIMBY syndrome. We learn most about the local protests from the media, about the reasons for the protests, NIMBA actors. The article gives examples of such protests regarding the location of a social institution. Examples come from public sources – local and national newspapers, internet sources. The development of events is tracked by the media up to a certain point – for example, reaching consent or moving away from the intention to locate the institution. For social workers, this is a sufficient package of information to take into account the potential resistance of residents. In this light, it is possible to predict the lack of consent of the local community to the neighborhood with a specific cat-egory of clients of social institution. Therefore, an appropriate information campaign, ahead of the implementation of the project, can protect investors by confronting the inhabitants of the city, time-consuming and expensive procedures, and above all negative emotions. Thanks to that avoidances of hostility, aggression towards employees of institutions, clients of institu-tions and objects of this institution will be avoided.
A social project as a tool for strengthening the care and educational potential of the parents – a case study on the example of the Konopiska municipality
Authors: Badora Magdalena Helena
Published: April 2019

The aim of this study is to present, on the basis of a case study of the Konopiska municipality, to what extent social assistance centres can use the social project to raise the parents’ care and educational competence and to promote correct parental attitudes. The article will discuss in detail the projects implemented by the Municipal Social Welfare Centre in Konopiska in the last eight years, including the project entitled „Rodzice na medal” („Perfect Parents”) which is the author’s bachelor’s thesis. In order for people experiencing problems related to parenthood to be able to obtain comprehensive assistance and professional knowledge, various types of special-ists were hired during the implemented projects, including a psychologist, pedagogue, dietitian, addiction thera-pist and sexologist. An important role in the projects was, of course, played by social workers, whose task was to conduct recruitment of parents and motivating them to actively participate in classes. Social workers also coop-erated with other institutions working for the benefit of the family in order to reach the largest possible number of people in need of strengthening the care and educational potential. The presented activities can be recom-mended as „good practice” and a voice in the discussion on the shape of social work with dysfunctional families and families experiencing difficulties in raising a child. The information contained in the article comes from project documentation, including applications for co-financing, reports on the implementation of tasks and correspondence exchanged between the Konopiska municipality and institutions providing subsidies.
An Initial Quantitative Attempt to Estimate How Much Louann Evaporite was Deposited in the Gulf of Mexico Basin
Authors: Fiduk J. Carl
Published: April 2019

Published estimates for the original volume of Mid-Jurassic Louann evaporites found throughout the entire Gulf of Mexico Basin vary widely. Volume totals derived from both map data and actual volume numbers, range from about 10,500 km3 (2,500 mi3) to 839,000 km3 (200,000 mi3), an 80 fold variation. Little new information has been published during the past twenty-five years to address this disparity. But gaining knowledge of the present day volume of salt would be an important metric if debates concerning the origin of the salt and the nature of the Gulf of Mexico Basin during salt deposition are to be reconciled.

A methodology now exists to estimate more accurately and quantitatively the volume of salt present in a given area. Multiple, recent generations of 3-D seismic depth volumes in the offshore Gulf of Mexico require that salt velocities be inserted. This vital processing step includes a systematic picking and interpretation of the tops and bases of all salt bodies encountered. The resulting models of salt velocity allow salt volume in the 3-D data sets to be calculated. Combining the salt volumes calculated from multiple seismic surveys offers new stratigraphic insights across large portions of the original salt basin.

A comparison of salt volumes derived from seismic data cubes and volumes derived from published maps can now be made. The comparisons should give some suggestion as to the accuracy of the map data. By extrapolation it should also give a more accurate and quantitative estimation of the original salt volume deposited in the Gulf of Mexico basin.
A Petroleum Systems Perspective on the Siliciclastic Cretaceous Play of the Eastern Mississippi Canyon, Gulf of Mexico
Authors: Edward Kovas , Michael Giallorenzo , Kirk Schafer , Jack Taylor
Published: April 2019

The eastern Mississippi Canyon area has long been known as a prolific Miocene oil and gas province. Organic rich shales and marls of Tithonian and Oxfordian age strata are considered the major source rocks in the region. Recently however, attention has been directed towards the intervening siliciclastic Cretaceous strata as an enticing exploration target.

This presentation focuses on the duality of the Cretaceous section as both a “first carrier” for hydrocarbons expelled from Late Jurassic source rocks and as a potentially significant “container” for hydrocarbon accumulations as well.

Examined are the petroleum system elements and processes of eastern Mississippi Canyon. Emphasis is placed on the relative roles of vertical versus lateral secondary hydrocarbon migration from source to trap. Fluid properties from sampled accumulations help constrain model-derived estimates of thermal maturation, migration timing, loss en route and potentially available hydrocarbon yield.

The “carrier/container” nature of the Cretaceous is characterized through multiple scenarios that address: Subsurface pressure relationships, bed-seal and fault properties; as well as seismically derived lithology and facies distributions. Fetch area constrained source rock expulsion through the Cretaceous is modeled, taking into account known Miocene accumulations. The results of such analyses lend insight into hydrocarbon potential within the Cretaceous.
Provenance of Cenozoic Siliciclastic Units in the Southern Gulf of Mexico by Heavy-Mineral Determinations and Geochemistry, and Detrital Zircon U-Pb Geochronology
Authors: Beltrán-Triviño Alejandro , Martens Uwe
Published: April 2019

We established provenance of Cenozoic sequences sampled in wells in the southern and southwestern Gulf of Mexico by heavy mineral analysis and LAICPMS detrital zircon U-Pb ages. The age spectra are dominated by Cenozoic ages. Other populations are of Cretaceous, Late Permian-Early Triassic, and Neo-Mesoproterozoic ages. Minor Jurassic, Devonian, and Ordovician ages are included.

Paleoproterozoic-Archean ages are related to the Amazonian craton. Meso-Neoproterozoic ages (1 Ga) are ubiquitous in Mexico (Oaxaquia terrane) and are related to the Grenville orogen. Neoproterozoic ages (750-550 Ma) were possibly derived from sedimentary rocks on the Panafrican orogen. Cambrian-Ordovician ages (490-450 Ma) might relate to plutons of the Esperanza suite of the Acatlán complex. Carboniferous and Permian ages (350-290 Ma) were possibly derived from the western Gondwanan arc. Permian and Triassic ages (290-250 Ma) may represent the east Mexican arc. Late Triassic and Jurassic ages (210-170 Ma) suggest a derivation from the Nazas arc in north-central Mexico. Late Jurassic ages (160 Ma) may represent the Jurassic magmatism associated with an extensional regime. Cretaceous ages (145 Ma) might be derived from Early Cretaceous arc of Mexico. Cretaceous ages (135-90 Ma) were possibly derived from the Alisitos-Peninsular Ranges arc. Late Cretaceous-Early Palaeogene ages (90-55 Ma) suggest relations with Laramide magmatism and the Late Cretaceous volcanic province in southern Mexico.

Paleogene-Neogene zircons (50 Ma and younger) are likely related to Cenozoic volcanic arcs in Mexico such as the Sierra Madre Occidental. Three earlier recognised ignimbrite flare-ups in the Eocene-Oligocene, early Oligocene, and early Miocene, match our detrital zircon populations. Furthermore, Miocene units contain kyanite-sillimanite possibly related to medium- to highgrade rocks such as the Acatlán complex or the Guatemalan Chuacús complex. We discuss the provenance based on geochemistry of the heavy minerals.
Lithological and Geochemical Analysis to Reduce Uncertainty in the Exploration of Unconventional Gas Deposits in the Burro-Picachos Basin, Northeastern Mexico
Authors: Alberto Herrera Palomo
Published: April 2019

In the search for unconventional reservoirs, one of the geological formations most studied in the United States is the Eagle Ford (Upper Cretaceous), which extends from the state of Texas in United States to the northeastern portion of the Mexican republic. The Eagle Ford Formation consists of argillaceous limestones and calcareous siltstone deposited in a mixed environment. These lithologies have petrophysical and geochemical characteristics sufficient to be considered as producing gas and/or oil, depending on the content of organic matter and the degree of maturity thermal reached.

In the northeast of the State of Coahuila, based on lithology, paleontological content, and TOC, Eagle Ford formation can be divided into three units:

Biozone A:

Biozone B:

Biozone C:

With the thickness distribution of the proposed units, it can be interpreted that the variation in the water depth depends on the topographic relief that prevailed in the Late Cretaceous (Cenomanian–Turonian) in the northeastern portion of Mexico: in a shelf and basin environment, influenced by Maverick Basin. Geochemical data analyzed and the proposed subdivision, indicates that Biozone C drive is the thickest, and has more TOC content in the northeastern part of the Burro-Picachos Basin; the predominant type of kerogen in the area is the type III.

Using the Dykstra-Parson method to determine the homogeneity of the distribution of values of each proposed unit, Biozone A has a higher degree of homogeneity than Biozone C. However, based on TOC and degree of homogeneity, Biozone B has a lower degree of exploration.
Integral Analysis of the Opening of the Gulf of Mexico and its Relationship with the Sedimentary Basins Generation
Authors: Cruz Tomas Rodríguez
Published: April 2019

This paper integrates, analyzes, and interprets the existing geological and geophysical information related to the opening of the Gulf of Mexico. The analysis of this information has the objective to consider the opening of the Gulf of Mexico as a result of global tectonic processes. Without doubt, the opening of the Gulf of Mexico has its origin in the interaction of two important tectonic events that generated the separation of Pangea: the Farallon Plate subduction in the Pacific and on the opening of the Central Atlantic, whose start is marked by the presence of the Central Atlantic magmatic province.

A proposal of this work is that as much oceanic crust was generated in the Oxfordian, as part of the stage in the Central Atlantic Jurassic opening. This Oxfordian period is characterized by a large positive geomagnetic chron, which explains the absence of polarity changes in the magnetic response for the Gulf of Mexico.

Another proposal is that the Sierra de Chiapas is the transpressional front that represents the final stage in the gulf opening and is associated with the edge effect of gravity anomaly that can be observed in the overall gravimetric maps.

The proposed model assumes that the magmatic arc causes continental rifting, creating basins containing red beds deposits that are located parallel to the orientation of the arc; these rifting areas evolve to form the subbasins of Chihuahua, Sabinas, and Burgos in the northeast of Mexico and Tampico Misantla, Veracruz, and Southeastern basins in eastern Mexico.
Giant Primary Retroperitoneal Serous Cystadenoma: A Rare Entity Mimicking Multiple Neoplastic and Nonneoplastic Processes
Authors: Chen Fengming , Jiang Kun
Published: April 2019

Serous cystadenoma, often known as ovarian serous cystadenoma, is one of the common benign ovarian neoplasms. On the other hand, primary retroperitoneal serous cystadenoma is an extremely rare benign entity whose pathogenesis has not been well understood. Clinical presentation and symptomatology vary greatly and are highly dependent on the size and location of the lesion. Primary retroperitoneal serous cystadenomas are homogeneous, unilocular, thin-walled cystic masses. If they grow large enough, they tend to compress and deform adjacent organs, giving clinicians a misimpression of malignant pattern of behavior. Therefore, it is crucial to differentiate benign primary retroperitoneal serous cystadenomas from other epithelial and nonepithelial cystic lesions or masses involving retroperitoneal regions. Management-wise, complete cyst excision without rupture or spillage of the cyst contents is the recommended therapeutic method for primary retroperitoneal serous cystadenomas. This review will highlight the current knowledge on its pathogenesis and discuss its histopathologic features and differential diagnoses from the pathologist's point of view.
Pseudomyogenic Hemangioendothelioma (Epithelioid Sarcoma-Like Hemangioendothelioma)
Authors: Caballero Gustavo A. , Roitman Pablo D.
Published: April 2019

Pseudomyogenic hemangioendothelioma (PMH) is a rare vascular tumor that presents more frequently in young adults and has a male predominance. It is usually located in the superficial or deep soft tissues of the extremities, but concurrent bone involvement can be present. In approximately two-thirds of patients this disease is multifocal, often involving multiple tissue planes. It is a relapsing lesion with low metastatic potential. Given its clinical and morphologic characteristics (multifocality, epithelioid morphology, absence of clearly evident vascular differentiation on hematoxylin-eosin slides), PMH can be easily misinterpreted as other lesions, often with radically different treatment and prognosis. For this reason, we think it is important to recognize this entity, which has some unique features. Here, we will briefly describe the clinical and pathologic features of PMH, detailing its more relevant differential diagnoses.
Wasted Spaces, Resisting People: the politics of waste in Naples, Italy
Authors: Armiero Marco , Sgueglia Leandro
Published: April 2019

This article explores how the waste crisis in Naples, which has been occurring since the 1990s, has stimulated the political creativeness of local activists who have started to experiment new ways for participation and community building. In particular, we investigate how environmental justice struggles have evolved in commoning processes (that is, in the creation of participatory institutions and in the defense of commons) by studying the social mobilization in Chiaiano, a neighborhood at the northern periphery of Naples (Italy). Using oral history interviews, documents produced by grassroots organizations, mass media reports, and our participants’ observation notes, we have analyzed the evolution of the mobilization in Chiaiano, the connections between environmental concerns and commoning, and the results in terms of social experimentation.Keywords: Environmental Justice. Commoning. Participatory Democracy. Waste. Naples (Italy).
La revanche de l’auteur
Authors: Randall Marilyn
Published: April 2019

La fiction se distinguerait du mensonge ou de la supercherie en étant une « feintise partagée » (Schaeffer) entre l’auteur et le lecteur, partenaires coopérants liés par un pacte de lecture où chacun respecte les règles du jeu. Pourtant, certaines fictions remettent en cause ce rapport de connivence en refusant de partager avec le lecteur le lieu ou la nature précis de la feintise qui serait dès lors non pas partagée mais plutôt dissimulée, et de ce fait non pas ludique mais sérieuse. La fiction moderne a largement exploité la figure du narrateur peu fiable comme source des erreurs, voire des mensonges desquels le lecteur tombe victime. Or, que conclure quand ce narrateur, bouc émissaire de l’auteur, n’existe pas? Nous explorerons un corpus de romans québécois où la fiction apparente est un leurre derrière lequel se dissimule le véritable lieu de la feintise, piégeant le lecteur dans des paradoxes sans issue. Ces pactes de lecture rompus ne peuvent pas être mis sur le compte d’un narrateur bouc émissaire mais plutôt sur celui de l’auteur réel — rusé, tricheur — qui s’impose comme autorité finale, tireur des ficelles non seulement du récit, mais de son lecteur.
Lire en mode conflictuel
Authors: Bérard Cassie
Published: April 2019

Partant de l’idée que les narrations non fiables dans les romans encouragent le lecteur à produire des lectures décisives, l’article cherche à saisir le processus par lequel s’effectue la reconstruction des univers fictionnels et se forge l’image des narrateurs. Il vise par ailleurs à explorer un mode particulier de lecture narrative : celui du conflit. Là où le lecteur accepte la non-fiabilité au cœur du récit afin d’en faire le lieu d’une lecture indécise, il réconcilie tous les possibles.
La documentation historique
Authors: Epp Marla
Published: April 2019

Nous examinons l’intégration de citations dans Les Onze et HHhH, deux romans à base d’archives avec un narrateur à la première personne qui se veut spécialiste d’histoire. Ce geste citationnel devrait, selon les historiens, produire de la fiabilité, mais n’a pas toujours l’effet escompté. Leur appropriation respective du style historique joue, dans les deux cas, avec les attentes du lecteur et provoque des interrogations quant à la représentation de l’histoire.
Volume 3 Numéro 1

En 2011 parut un important rapport posant un diagnostic sur la situation des arts autochtones au Canada. Préparé par France Trépanier et Chris Creighton-Keelly pour le Service de la recherche et de l’évaluation du Conseil des Arts du Canada, ce document faisait état d’une double discrimination touchant les artistes autochtones francophones. Non seulement ces derniers sont-ils, par rapport aux artistes allochtones, moins représentés dans les médias et les institutions, mais une marginalisation supplémentaire les touche en raison de leur langue.
Climate change, deforestation patterns, freshwater availability and cultural shifts on prehistoric Easter Island (SE Pacific)
Authors: Rull Valenti
Published: April 2019

The remote and isolated Easter Island (Rapa Nui) has been the arena for classic debates on the potential consequences of human overexploitation of natural resources as a microcosmic model for the whole planet. Human-deterministic hypotheses have traditionally been preferred to proposals involving climate changes as drivers of socioecological shifts, especially in relation to the collapse of the ancient Rapanui civilization inhabiting the island before European contact (1722 CE). However, recent paleoecological studies have provided evidence for past climatic shifts, especially droughts, which have stimulated a paradigm shift from deterministic and exclusive views to a more holistic framework that considers both natural and anthropogenic factors as well as their feedbacks and synergies. This paper reviews the latest climatic, ecological and cultural reconstructions of precontact times and evaluates the potential impact of the different drivers on socioecological shifts. Especially noteworthy is the occurrence of some droughts in the last millennium that, coupled with human deforestation, severely affected the access of the prehistoric Rapanui civilization to freshwater but did not compromise the continuity of this ancient culture. Two main hypotheses have been proposed for how the Rapanui bypassed freshwater scarcity. According to the intraisland migration hypothesis, the latest drought recorded (1570-1720 CE) would have led to the abandonment of the former cultural center of the ancient Rapanui civilization (Lake Raraku) to move to Lake Kao, which became the new cultural core. This would have been linked to a profound cultural shift from the moai cult to the Birdman cult. In contrast, the coastal groundwater hypothesis proposes that coastal seeps were the main freshwater source during climatic droughts. These hypotheses are evaluated using the available archaeological and paleoecological evidence, and it is concluded that neither can be rejected; therefore, they could be complementary, rather than exclusive. The continuity of the Rapanui civilization in spite of landscape degradation is a good example of cultural resilience that challenges earlier deterministic explanations and emphasizes human adaptability to changing environments.

Published: April 2019

The article constitutes an attempt to examine dictionary structures functioning as keywords. Here, the term keyword is understood as a key to the knowledge represented by lexicographic data. The study aims to investigate which of the following, namely, macro-, micro- or mediostructure, is used for conveying linguistic and encyclopedic informations in a dictionary. Within this framework, ways in which the said structures are correlated with one another and the access path of a dictionary are presented. The main objects of investigation are German-Polish and Polish-German dictionaries of specialist economic terms.
Impact of Farm Mechanization on Cropping Pattern and Cropping Intensity - A Case Study from Assam, India
Authors: Barman Sinki , Deka Nivedita , Deka Pallavi
Published: April 2019

Farm mechanization is considered as important pathways of agricultural development. A farming system cannot sustain with the traditional system. The mechanization of farm is also inductive to the diversification of the cropping pattern as it enables farmer to raise a second crop or multi crop ultimately raising cropping intensity. The study was conducted in Central Brahmaputra Valley and Upper Brahmaputra Valley Zone of Assam, India. The objective of the study is to examine the effect of mechanization on cropping pattern and cropping intensity .Primary data were collected with the help of specially design pretested schedule by interview method. Thus, a sample of 240 farmers had been taken for the study. Cropping intensity was higher in case of all mechanize farm than bullock operated farm not only individual size groups but all farm size taken together. Tractor Hired Farm had the highest cropping intensity (162.21 per cent) followed by Power Tiller Hired Farm (161.49 per cent) and Tractor Operated Farm (152.00) per cent) and Power Tiller Operated Farm (154.62 per cent), respectively. In case Bullock Operated Farm  cropping intensity showed positive relationship with farm size but reverse was the in case of each  mechanized farm. Mechanized farm had higher cropping intensity which was confirmed by regression analysis that in all the categories of farm had positive significant relationship with cropping intensity but farm size and cropping intensity had highly significant inverse relationship. Cropping pattern of different categories of mechanized farms slightly shifted to high valued crops while in case of Bullock Operated Farm it was remain sali rice biased as usual. Mechanization showed an impact on increasing cropping intensities in the study area where Tractor Ownership Farm by hiring appeared to be the most important form of mechanization as it depicted a very high significant relationship with the cropping intensity in the study area. Cooperative management of farm machinery, financing of second-hand tractors for small farmers should be given for strengthening mechanization amongst the small farmers in the study area.
