Global re-analysis datasets to improve hydrological assessment and snow water equivalent estimation in a sub-Arctic watershed
Authors: Casson David R. , Werner Micha , Weerts Albrecht , Solomatine Dimitri
Published: September 2018

Abstract. Hydrological modelling in the Canadian sub-Arctic is hindered by sparse
meteorological and snowpack data. The snow water equivalent (SWE) of the winter
snowpack is a key predictor and driver of spring flow, but the use of SWE
data in hydrological applications is limited due to high uncertainty. Global
re-analysis datasets that provide gridded meteorological and SWE data may be
well suited to improve hydrological assessment and snowpack simulation. To
investigate representation of hydrological processes and SWE for application
in hydropower operations, global re-analysis datasets covering 1979–2014
from the European Union FP7 eartH2Observe project are applied to global and
local conceptual hydrological models. The recently developed Multi-Source
Weighted-Ensemble Precipitation (MSWEP) and the WATCH Forcing Data applied to
ERA-Interim data (WFDEI) are used to simulate snowpack accumulation, spring
snowmelt volume and annual streamflow. The GlobSnow-2 SWE product funded by
the European Space Agency with daily coverage from 1979 to 2014 is evaluated
against in situ SWE measurement over the local watershed. Results demonstrate
the successful application of global datasets for streamflow prediction,
snowpack accumulation and snowmelt timing in a snowmelt-driven sub-Arctic
watershed. The study was unable to demonstrate statistically significant
correlations (p < 0.05) among the measured snowpack, global
hydrological model and GlobSnow-2 SWE compared to snowmelt runoff volume or peak
discharge. The GlobSnow-2 product is found to under-predict late-season
snowpacks over the study area and shows a premature decline of SWE prior to
the true onset of the snowmelt. Of the datasets tested, the MSWEP
precipitation results in annual SWE estimates that are better predictors of
snowmelt volume and peak discharge than the WFDEI or GlobSnow-2. This study
demonstrates the operational and scientific utility of the global re-analysis
datasets in the sub-Arctic, although knowledge gaps remain in global
satellite-based datasets for snowpack representation, for example the
relationship between passive-microwave-measured SWE to snowmelt runoff
volume.
Mechanisms leading to the 2016 giant twin glacier collapses, Aru Range, Tibet

Published: September 2018

Abstract. In north-western Tibet (34.0∘ N, 82.2∘ E) near
lake Aru Co, the entire ablation areas of two glaciers (Aru-1 and Aru-2)
suddenly collapsed on 17 July and 21 September 2016. The
masses transformed into ice avalanches with volumes of 68 and 83×106 m3 and ran out up to 7 km in horizontal distance, killing nine
people. The only similar event currently documented is the 130×106 m3 Kolka Glacier rock and ice avalanche of 2002 (Caucasus
Mountains). Using climatic reanalysis, remote sensing, and three-dimensional
thermo-mechanical modelling, we reconstructed the Aru glaciers'
thermal regimes, thicknesses, velocities, basal shear stresses, and ice
damage prior to the collapse in detail. Thereby, we highlight the potential of using
emergence velocities to constrain basal friction in mountain glacier models.
We show that the frictional change leading to the Aru collapses occurred in
the temperate areas of the polythermal glaciers and is not related to a
rapid thawing of cold-based ice. The two glaciers experienced a similar
stress transfer from predominant basal drag towards predominant lateral
shearing in the detachment areas and during the 5–6 years before the
collapses. A high-friction patch is found under the Aru-2 glacier tongue,
but not under the Aru-1 glacier. This difference led to disparate behaviour
of both glaciers, making the development of the instability more visible for
the Aru-1 glacier through enhanced crevassing and terminus advance over a
longer period. In comparison, these signs were observable only over a few
days to weeks (crevasses) or were absent (advance) for the Aru-2 glacier. Field
investigations reveal that those two glaciers were underlain by soft, highly
erodible, and fine-grained sedimentary lithologies. We propose that the specific
bedrock lithology played a key role in the two Tibet and the Caucasus
Mountains giant glacier collapses documented to date by producing low bed
roughness and large amounts of till, rich in clay and silt with a low friction
angle. The twin 2016 Aru collapses would thus have been driven by a failing
basal substrate linked to increasing pore water pressure in the subglacial
drainage system in response to increases in surface melting and rain
during the 5–6 years preceding the collapse dates.
Trained and Non-Trained Language Teachers on CLIL Methodology: Teachers’ Facts and Opinions about the CLIL Approach in the Primary Education Context in Spain
Authors: Alcaraz-Mármol Gema
Published: September 2018

Since the early 2000s, there seems to be a growing interest in bilingual education in Spain. The need for teachers with certain accreditation in foreign language proficiency has been growing in the last decade. Yet, the methodological basis to integrate content and language in the classroom does not seem to be a compulsory requirement. The participants of this study were surveyed about several aspects of their teaching practice. We compared the answers of those who have received specific methodological CLIL training and those who have not. Results show that methodological training beyond just foreign language teaching makes significant differences in terms of the teachers’ opinions on CLIL and practice of using bilingual practices in their classrooms, making use of a wider variety of activities and resources. Differences were found in the way they see their own teaching, their use of their L1, materials in the classroom, and the variety and type of activities they develop with their students.
Analyzing a Pre-Service EFL Program through the Lenses of the CLIL Approach at the University of Cuenca-Ecuador
Authors: Argudo Juanita , Abad Mónica , Fajardo-Dack Tammy , Cabrera Patricio
Published: September 2018

The recent application of Content and Language Integrated Learning programs in higher education provides an extensive area for research due to the quick implementation of English as the medium of instruction for university programs, as well as to the need of university students around the world to communicate through English and to try different learning strategies and methodologies than the ones they used to work with. This study aimed to estimate the extent to which the English as a Foreign Language (EFL) program at the University of Cuenca designed for students who wish to become EFL teachers complies with the principles of the Content and Language Integrated Learning approach. The 121 participants of this study were students from the fourth, fifth, and seventh semesters of the program. A general proficiency English test was administered to these students; some writing assignments to evaluate the development of Higher Order Thinking Skills were considered; and a survey to inquire about students’ perceptions on the development of language, content, and Higher Order Thinking Skills in their content subject classes was also applied. The findings revealed that 52% of the students are between A1 and A2 level according to the Common European Framework of Reference for Languages; this means that they do not have the necessary linguistic conditions to take content subjects. It seems that the parameters teachers used to plan their classes do not consider the three dimensions of this approach (content, language, and procedures); therefore, students are not developing these dimensions simultaneously.
Narratives of Desire, Love, Imagination, and Fluidity: Becoming an English Teacher in a University Preparation Program
Authors: Sarasa Maria Cristina , Porta Luis Gabriel
Published: September 2018

This is a narrative study into the co-construction of teaching identities narrated by twenty-four undergraduate students in the context of an English language teacher education program in Argentina. Teacher identities are defined in the literature as co-authored stories of living and becoming. Our method uses narrative inquiry to study lived experiences as co-narrated phenomena. The narrative analysis of different texts gathered in the teacher education program allowed the co-composition of each participant’s identity story. Results first display thematizations of identity strands in these narratives involving emotions—love, desire, imagination, and fluidity. Next, participants’ negotiation of their processes of becoming through these emotions are retold. The discussion examines results considering state-of-the-art literature. The conclusions summarize the implications of the research for English language teacher initial university education.
Lukács and the Project of a Marxist Literary History: Balzac and Dostoevsky
Authors: Smetona Matthew J.
Published: September 2018

This article attempts to further the understanding of the Balzac-Dostoevsky relation by returning to the social analysis offered by Georg Lukács and by developing that analysis from the standpoint of his distinctive understanding of Marxist criticism. Certain key aspects of Balzac's critique of nascent capitalist society are inherited by Dostoevsky, and many such aspects are transferred fruitfully from restoration Paris to tsarist Petersburg, as this article will seek to demonstrate. These critical elements are developed by the latter author along psychological lines that deepen Balzac's original materialist analysis. In the novella and novel considered here, Dostoevsky displays particular acumen in his depictions of the inhumanity of the incipient capitalist order, despite the illusory romanticism and even irrationalism to which he holds fast. By contrast, such irrationalist strands are not to be found in the novels of Balzac considered here, as well as no illusions regarding the possibility of a return to a “golden age” before the capitalist process of reification had begun. Thus these novels of Balzac are not characterized by the problematic tendencies at work in those of Dostoevsky, and this fact, it is argued here, compels us to follow Lukács in according priority to Balzac.
On “zero” and semantic plurality
Authors: Bylinina Lisa , Nouwen Rick
Published: September 2018

We discuss the semantics of prenominal “zero”, as in “I have zero new emails in my inbox”. We show that “zero” is not a quantifier like “no” and that giving “zero” a regular numeral semantics is possible and desirable. We formulate such an analysis and its consequences. We show that the existence of a zero numeral has profound consequences for linguistic semantics. We conclude that the fact that languages allow ascription of zero quantity to an entity provides evidence that linguistic semantics has access to what at first sight may seem like an ontological oddity: an entity with zero quantity. In other words, we will show that studying “zero” can inform us about the underlying semantic ontology of natural language.
The Influence of Pension Scheme Maturity on Investment Strategies of Pension Funds in Kenya
Authors: Ngugi Wilson , Njuguna Amos , Wambalaba Francis
Published: September 2018

The longevity risk borne by members of defined contribution pension schemes and the funding risk borne by sponsors of defined benefit pension funds have shifted attention to the investment strategies employed by pension funds. We use secondary data from 206 occupational retirement benefits schemes in Kenya, to examine the influence of pension scheme maturity on investment strategies. We then triangulate the results using focused group discussions with industry experts. Results from the regression models indicate that scheme maturity does not influence the investment strategies of occupation schemes in Kenya contrary to life cycle theory. The Retirement Benefits Authority and trustees of retirement benefits schemes in Kenya are advised to offer members’ investment choices coupled with education to enable them make decisions to reduce their exposure to risky assets as they age.
Service Dominant Logic, Open Innovation Intermediaries and Innovative Capacities: Towards a Theoretical Framework
Authors: Perano Mirko , Luca Casali Gian , Abbate Tindara
Published: September 2018

This work stresses the centrality of the Service-Dominant Logic (S-D logic) point of view and the relationships between firm and Open Innovation Intermediary in the knowledge development process providing a conceptual framework. From an in-depth literature review on S-D logic, Open Innovation Intermediaries and firm dynamic capabilities, a development of a conceptual framework based on these research areas is provided. The framework is intended to highlight the role of customers (firms) into professional relationships with intermediaries of innovation becomes progressively significant in the innovation activities because these professional relationships increasingly become co-creators of value. Within their advanced platforms, intermediaries or brokers, encourage, promote and sustain interactions and partnerships aligned to value co-creation enterprises. This is achieved by providing a heterogeneous set of services to augment dynamic cooperation, to advance concepts or solutions for solving interdisciplinary problems and, consequently, to address an organization’s requirements for new market opportunities. Therefore, these partnerships represent a possible way to define and to improve the value cocreation actions by firms that intend to engage and to cooperate with adjunctive and integrative resources and expertise. In addition, the framework has been designed to highlight a particular domain centered on the role of each S-D Logic axioms within the innovation capabilities; and the relationship and orientation between organisation and innovation intermediary. The main findings highlight that both firms and Open Innovation Intermediaries need to develop innovative capabilities through direct and indirect relationships within the S-D logic perspective. This study is an effort towards building a conceptual framework by connecting the concepts of Open Innovation Intermediaries, dynamic capabilities and S-D logic.
How Did Organizational Resilience Work Before and after the Financial Crisis? An Empirical Study
Authors: Palmi Pamela , Morrone Domenico , Paolo Miglietta Pier , Fusco Giulio
Published: September 2018

The purpose of this paper is to assess the role of organizational resilience as an attitude, depending on the adoption of corporate governance, environmental and social practices (CESPs), in order to react to unexpected shocks, while preserving business sustainability. Organizational resilience is defined as the capacity for an enterprise to survive, to adapt and to grow in a turbulent change or unpredicted situation. Since organizational resilience is a latent path-dependent construct, it can be evaluated through long-term outcomes in an integrated perspective. The hypotheses are tested analyzing the economic performance of U.S. companies listed in Standard & Poor’s 500 index (S&P 500) and their environmental, social and governance (ESG) data has been extracted from Asset4. The period in the study covers 14 years, from 2002 to 2015, collecting the seven years before and after the 2008 financial crisis. The results of the empirical analysis highlight that economic performances of listed companies are influenced, over the 14 year period considered in the study, not only by the traditional sustainable pillars (SEPs), but also by the corporate governance ones (CESPs).
Effects of Work-life Balance Policies on Corporate Performance and the Promotion of Female Employee
Authors: Takeuchi Mamiko
Published: September 2018

Based on a survey conducted among Japanese pharmaceutical companies, this study analyzes the processes and influence of work-life balance policies on the promotion of women employees and corporate performance as a result of women’s activities. Structural equation modeling is used to clarify the complex causality between the promotion of women employees and personnel policies. The results of our analysis indicate that even if the complex relationships among the variables are considered, productive improvements from work-life balance policies are not observed. Although work-life balance policies do not have a direct effect on the promotion or wages of women, they have an indirect effect on women’s promotions and wage increases over the length of their tenure.
Kids’ Empathic Development Scale: Turkish Language Validity and Reliability
Authors: Leana-Taşcılar Marilena Z. , Biber Mahir , Kurt Tunç
Published: September 2018

Empathy is one of the skills that we need in order to understand the emotions of other people. Although many empathy scales exist, few are designed for children. The Kids’ Empathic Development Scale (KEDS) can be applied onward of age 6 and provide information about empathy’s affective, cognitive and behavioural components. The aim of this study is to present the Turkish validity study of KEDS and to provide a new tool that has satisfactory psychometric properties. Nine language experts made the translation and back translation form English to Turkish and vice versa. After that, the experts asked to rate the translation validity. According to experts’ opinions, the appropriate level of the items in the scale varied between 4.60 and 5.00 (X= 4.80, SD = .44). The results indicated that the Turkish scale closely approximated with the original. The scale’s language validity, analyses were performed on 30 (21 girls, 9 boys, average age = 9.5, SD = 1.17), bilingual students. Analysis, which was performed between the English and Turkish forms, showed that only the item I7_1 was found out to be problematic. Afterward, the scale’s language validity was ensured and easily accessible sampling method was adopted, and then it was applied to 293 (144 girls, 149 boys) students who were attending in seven different schools (four public, three private). Correlation analysis, which was performed to test concurrent validity, showed that there is a positive correlation (p < .01) between the total scores of Children’s Empathy Scale and Kids’ Empathic Development Scale. The results of variance analysis, which were performed in order to test if the empathy scores vary according to age, were significant as follows: total empathy score F (4, 248) = 3.10, p < .05, affective F (4, 251) = 4.70, p < .01, cognitive F (4, 250) = 2.6, p < .05 and behavioural F (4, 248) = 4.09, p < .01. Taking into consideration the gender variable not significant results were obtained. The results of the study showed that the Turkish version of KEDS is a valid and reliable, and has acceptable psychometric properties.
Grade Inflation: Causes, Consequences and Cure
Authors: Chowdhury Faieza
Published: September 2018

Academic institutions worldwide, from primary schools to universities, use grades or marks as a fundamental sorting and signaling mechanism for students. The grades awarded to students should be indicative of learning outcomes. However, do the grades awarded today accurately reflect student achievement in the classroom? Grade inflation has become a widespread phenomenon within the education system in the past thirty years, garnering massive condemnation among educators, researchers and the public. Some people even view grade inflation as a scandal, an injustice and a violation of student trust. Nevertheless, there are some academic institutions that find it convenient to ignore this problem and, in some cases, encourage the practice. In this paper, we examine the various factors that can contribute to grade inflation. Additionally, we assess how grade inflation can create problems for students, faculty, and society as a whole. Finally, we provide some suggestions and recommendations to solve the problems of grade inflation.
Age-related Effects of Speed and Power on Agility Performance of Young Soccer Players
Authors: ATEŞ Bahar
Published: September 2018

The purpose of this study is to determine the age-related effects of power and running speed on agility ability of young soccer players. A total of eighty-one soccer players, who do not have professional contracts with any professional club but play for various local and school teams on a regular basis, have participated (mean age: 17.7±1.16, range 16–19) in this study. Tests consist of anthropometric variables, power and speed measurements, and the agility test (T-Agility). At the completion of the warm-up protocol, players completed assessments of countermovement jump (CMJ), squat jump (SJ), speed (10-, and 30-m sprints, respectively), and the agility test (Agility T-Test). An analysis of variance (ANOVA) analysis was used to compare the parameters between each group and Pearson correlation analyses were applied to determine the relationships between agility test, speed, and power. When evaluated by age, only U16 players displayed moderate correlation between Agility T-Test and S10m and S30m (P<0.05). The only significantly weak correlation was found between the Agility T-Test and S30m for U19 players (P<0.05). Similarly, the only significantly weak correlation was found between the Agility T-Test and CMJ and SJ for U19 players (P<0.05). In conclusion, the results showed that speed and lower extremity power should not be considered as important predictors of agility performance in young athletes.
Exploring the Transitional Era in Saudi Arabia Journalism Discourse and the Path towards the Right to Freedom of Expression
Authors: Alnajrani Hassan , Bajnaid Ayman , Elyas Tariq , Masa’deh Ra’ed
Published: September 2018

This study investigates the role of non-state religious and cultural factors in determining a journalist’s freedom of expression in Saudi Arabia. Content analysis and quantitative research are used to determine the factors that impact freedom of expression. ‘Social responsibility theory’ is incorporated into the analysis in order to establish the connection between journalists and the community, specifically with respect to their interaction with non-state factors. The data for the study is collected and interpreted in two steps: first, news about events in Medina newspaper is examined; second, interviews with Saudi journalists are conducted and analyzed by implementing a semi-structure approach. The results confirm the relationship between non-state factors (such as culture and religion) and freedom of expression for Saudi journalists. Also, the religious background of Saudi journalists appears to affect their right to practice freedom of expression; for instance, some journalists with specific religious views avoid writing about rape and drugs crimes. In addition, journalists change their tribal and family names to escape judgment and work freely. Finally, some concluding remarks are provided about the responsibility of Saudi journalists to protect the image of Saudi Arabian society.
ESTIMATION OF VERTICAL DUST EMISSION FLUX AT A SITE IN THE MONGOLIAN GOBI DURING A DUST STORM PERIOD
Authors: D Jugder
Published: September 2018

A meteorological and dust monitoring tower with 20 m height set up at a Nomgon site in Umnugobi Aimag in the Mongolian Gobi in 2010. The Nomgon monitoring tower equipped with wind speed sensors at 2, 4, 10 and 20 m height above the ground level (AGL), a wind direction sensor at 10 m height, a sonic anemometer to measure turbulent momentum flux at 8 m height and a soil moisture sensor at 5 cm depth. We had a purpose to measure dust concentration of PM10 at two levels using Dust-Trak instruments during an intensive observation period (IOP) of a dust event in spring. A dust storm was expected in the Mongolian Gobi from 30 April to 1 May 2016 and two Dust-Traks were set at 0.9 and 2.95 m heights in the tower during this IOP for measuring PM10. Wind data at 2 and 10 m height, three wind components at 8 m height by a sonic anemometer, soil moisture (volumetric water content) data in 5 cm depth and dust concentrations of PM10 at two levels are used in this study. These data from the sensors and instruments in the tower were used for estimation friction velocity and vertical dust flux at the Nomgon site. In association with a surface cyclone, its frontal system and a trough aloft, the expected dust storm occurred in the Mongolian Gobi during the IOP period. Dust concentrations of PM10 increased during the dust storm period due to raised wind speed in the dry conditions of air and soil. The present study aimed to estimate friction velocity (u*) and vertical dust flux (F) around Nomgon site in the Mongolian Gobi desert during the dust storm period. The estimation results were presented in this paper.
Place of phytotherapy in the treatment of acute infections of upper respiratory tract and upper gastrointestinal tract
Authors: Pietruszewska Wioletta , Barańska Magda , Wielgat Jakub
Published: September 2018

Acute infections of the upper respiratory tract and upper gastrointestinal tract (mouth and throat) are still the most
common reason for reporting to the general practitioner or ENT specialist. Despite the fact that the most common
causative agent of these diseases are virurs, antibiotics are still flavored in about 60-80% of patients who report to the
doctor. In consensus such as EPOS, WHO reports and other local / national reports, there is a need to limit antibacterial
treatment for symptomatic and anti-inflammatory drugs. In addition to intranasal steroids and mucocutaneous
decongestants, supplementary treatment should be considered which resolves persistent symptoms. Plant preparations
are used here. The growing role of rational phytotherapy is emphasized, especially due to the most frequent etiological factor of these infections, i.e. viruses. Modern phytotherapy is part of pharmacology, and all preparations
based on plants meet the standards for medicines and are subject to standard registration procedures. The article discusses
the use and mechanism of action of selected herbs, among others: sorrel, elderberry, yarrow and horsetail in
the treatment of upper respiratory tract infections and upper gastrointestinal tract. The phytotherapy show good efficacy
and tolerance, and can be used both in children and adults in recurrent infections of the upper respiratory tract. It
is worth paying attention to the combined preparations, the components of which have the effect confirmed by randomized
trials and long-term registration for use in treatment, both during the first signs of cold and its further duration,
and supportive in chronic inflammation especially of the paranasal sinuses.
Evaluation of Biomarkers in Multiple Ipsilateral Synchronous Invasive Breast Carcinomas
Authors: Navale Pooja , Bleiweiss Ira J. , Jaffer Shabnam , Nayak Anupma
Published: September 2018

Context.—

The College of American Pathologists guidelines recommend testing additional tumor foci in multifocal invasive breast carcinomas for the biomarkers estrogen receptor (ER), progesterone receptor, and HER2 only if the carcinomas show different morphologies or grades.

Objective.—

To assess clinical significance of testing for biomarkers in additional tumor foci in multifocal invasive breast tumors.

Design.—

Retrospective analysis of 118 patients diagnosed with ipsilateral synchronous multifocal breast carcinomas from January 2015 through March 2016 at Mount Sinai Hospital (New York, New York).

Results.—

Eighty-six cases were tested for at least 1 of the 3 biomarkers in additional tumor foci. Fifteen cases (17%) showed discordant staining between the 2 foci for at least one biomarker. Of the 7 of 67 ER-discordant cases (10%), 4 (57%) showed major variation from negative to positive expression, including 3 cases in which a smaller tumor focus was strongly positive for ER whereas the index tumor was negative. Similarly, within the 7 of 67 progesterone receptor–discordant cases (10%), 4 (57%) showed major variation from negative to positive, and in 3 cases with major discordance, the index tumor was negative for progesterone receptor, whereas a smaller focus was positive. A difference in HER2 expression was noted in 5 of 86 cases (6%). In only 5 of the 15 patients (33%) with discordant results, biomarker testing on additional foci would have been offered per the College of American Pathologists recommendations because of differences in histology or grading. Of the remaining 10 patients, 7 (70%) with positive results on smaller foci would have been deprived of appropriate adjuvant systemic treatment if the smaller focus had not been tested.

Conclusions.—

We propose that negative values expressed in the primary tumor be repeated routinely on additional ipsilateral synchronous tumors.
How the eyes add fractions: Adult eye movement patterns during fraction addition problems
Authors: Obersteiner Andreas , Staudinger Isabella
Published: September 2018

Recent studies have tracked eye movements to assess the cognitive processes involved in fraction comparison. This study advances that work by assessing eye movements during the more complex task of fraction addition. Adults mentally solved fraction addition problems that were presented on a computer screen. The study included four types of problems. The two fractions in each problem had either like denominators (e.g., 3/7 + 2/7), or unlike denominators exhibiting one of the following relationships: one denominator was a multiple of the other denominator (e.g., 2/3 + 1/9), both denominators were prime numbers (e.g., 2/7 + 3/5), or both denominators had a common divisor larger than one (e.g., 5/6 + 3/8). Self-reports, accuracy, and response times confirmed that participants adapted their strategy use according to problem type. We analysed the number of eye fixations on each fraction component, as well as the number of saccades (rapid eye movements) between fixations on components. We found that participants predominantly processed the fraction components separately rather than processing the overall fraction magnitudes. Alternating between the two denominators appeared to be the dominant process, although in problems with common denominators alternating between numerators was dominant. Participants rarely used diagonal saccades in any of the problems, which would indicate cross-multiplication. Our findings suggest that adults adapt their cognitive processes of fraction addition according to problem type. We discuss the implications of our findings for numerical cognition and mathematics education, as well as the limitations of our current understanding of eye movement patterns.

Нема сумње да је једна оваква књига апсолутно до-бродошла, с обзиром на то да је књижевност за дјецу углавном маргина-лизована у оквирима науке о књижевности.

Carcinogen treatment leads to mitotic defects and arrest in cancer and noncancer cells
Authors: Hartling Rebecca G , Pacheco Christian J , Bystrak Emily A , Quintyne Nicholas J
Published: September 2018

Genomic instability can manifest due to both chromosomal rearrangements and gain and loss of entire chromosomes. One mechanism by which a carcinogen acts is by increasing the rate of mitotic spindle defects during proliferation. These defects can lead to chromosomal instability that manifest as lagging chromosomes, anaphase bridges, or multipolar spindles. While several mechanisms exist to rectify these errors prior to completion of mitosis, some cells will escape repair, while others will prematurely exit mitosis. Here we examine the effects of two carcinogenic molecules: Fulvestrant, a chemotherapeutic that functions as a selective estrogen receptor degrader, and vinyl chloride, a hydrocarbon used to produce PVC. We exposed two cancer lines, A549 and UPCI:SCC103, and one noncancer line, GM03349, to increasing concentrations of the carcinogen for increasing durations, up to 48 hours exposure. We found that exposure to the carcinogen lowered the mitotic index in the cancer cell lines, while raising it in the noncancer line. Concurrently, we observed massive increases in the frequency of mitotic defects, with the most significant increases seen in prevalence of lagging chromosomes in prometaphase and metaphase and anaphase bridges. Live cell imaging showed that the occurrence of either of these defects had the strongest correlation with the likelihood that the cell would fail to complete mitosis. We also show that washing out the carcinogen decreases the frequency of mitotic defects in all three cell lines, but the mitotic index does not recover in the cancer cells. These findings demonstrate that carcinogen-induced mitotic defects have marked effects on the proliferative population of cells in terms of potential for contributing to chromosomal instability or removal from that population.
A protocol for rapid evidence synthesis into soil loosening as an intervention to ameliorate compaction caused by dairy farming and the impacts of this for productivity and sustainability
Authors: Kendall Helen , Taylor Amy , Reed Mark , Stewart Gavin
Published: September 2018

This is a protocol for a rapid review of the effectiveness of soil loosening to ameliorate compaction caused by cattle treading from dairy production on UK dairy farms. The review will synthesise relevant literature that explores the impacts that can be derived from mechanical soil loosening for improved soil quality, productivity (i.e. yield) and the environment. The protocol outlines the rationale, objectives, inclusion criteria, search strategy and screening processes for the meta-analysis, and the plans for data extraction, risk of bias and data synthesis approaches.
The stream power variation in a GIS environment as an index to evaluate the most 'sensitive' points of a river
Authors: De Rosa Pierluigi , Cencetti Corrado , Fredduzzi Andrea
Published: September 2018

The note deals with the problem of measurement and variability, along the fluvial reaches of a hydrographic network, of the stream power, according to the original definition provided by Bagnold (1966) “The available power supply, or time rate of energy supply, to unit lenght of a stream is clearly the time rate of liberation in kinetic form of the liquid’s potential energy as it descends the gravity slope S”. In formula:

Ω = ρ g Q S

where: Ω = stream power per unit of flow length (W/m) ρ g = density x gravity acceleration = specific weight of the fluid (kg/m3) Q = liquid discharge (m3/s) S = slope of the considered reach (m/m).

Recent digital elevation models allow the calculation of channel gradient and consequently stream power with a finer spatial resolution, opening promising and novel opportunities to investigate river geomorphical processes and forms.

The work carried out consisted in defining and implementing a methodological approach that could be automated within a geographic information system and that meets two requirements: 1) use input data that is easy to find as DEM at a low resolution; 2) estimate, in the best possible way and on the basis of the available data, the stream power and its variability along the considered stream. In particular, the methodological approach has been implemented in GIS environment (GRASS Gis, Qgis), and it has been applied to a sample basin, highlighting the variability of Ω along the streams of a higher order (in practice the main stream and its most important tributaries). The sudden and more substantial variations of stream power were then related to the processes acting in the fluvial system.

This approach has made it possible to highlight how the erosion, solid transport and sedimentation phenomena occurring along the fluvial reaches (and the geomorphological and geologicalapplicative problems that these involve, especially in anthropized areas), are correlated precisely to abrupt variations (increase/decrease) of the ”power” available. Hence the idea that automated and standardized screening of stream power variability along a stream can be used as a preliminary diagnostic element to identify the most ”sensitive” points of the same, on which to concentrate subsequent investigations (field checks, to verify the causes), aimed at mitigating the risk due to the dynamics of the riverbed.
Biodiversity surveys reveal eight new species of freshwater crabs (Decapoda: Brachyura: Potamidae) from Yunnan Province, China
Authors: Naruse Tohru , Chia Jing En , Zhou Xianmin
Published: September 2018

Yunnan Province is known to host the highest species diversity of the true freshwater crabs in China; 50 species have been recorded from the province by 2017. In 2004, our team conducted a biodiversity survey of the freshwater crabs in Yunnan Province to determine how well the diversity of crabs in the area has been characterized. We collected a total of 25 species, of which nine species proved to be new to science, and eight of which are described here. These include four species of the genusIndochinamonYeo & Ng, 2007, two species of the genusPotamiscusAlcock, 1909, and one species each of the generaPararangunaDai & Chen, 1985, andParvuspotamonDai & Bo, 1994. The new species ofPararangunaandParvuspotamonrepresent the second species of respective genera, which are here redefined. Detailed comparisons with morphologically allied species are provided. Photographs of the type specimens of their comparative species which are poorly illustrated in the literature are also provided to allow better understanding of their morphology. This study brings the number of the freshwater crabs of Yunnan Province to 58. Since about 13.8% of the number of species (eight out of 58 species) is increased by surveys conducted within a relatively short period, it is most probable that the species diversity of this group is still understudied in Yunnan Province.
The palaeoenvironment of the Upper Cretaceous (Cenomanian–Turonian) portion of the Winton Formation, Queensland, Australia
Authors: Fletcher Tamara L. , Moss Patrick T. , Salisbury Steven W.
Published: September 2018

The Winton Formation is increasingly recognised as an important source of information about the Cretaceous of Australia, and, more broadly, the palaeobiogeographic history of eastern Gondwana. With more precise dating and stratigraphic controls starting to provide temporal context to the geological and palaeontological understanding of this formation, it is timely to reassess the palaeoenvironment in which it was deposited. This new understanding helps to further differentiate the upper, most-studied portion of the formation (Cenomanian–Turonian) from the lower portions (Albian–Cenomanian), allowing a coherent picture of the ecosystem to emerge. Temperatures during the deposition of the Upper Cretaceous portion of the Winton Formation were warm, with high, seasonal rainfall, but not as extreme as the modern monsoon. The landscape was heterogeneous, a freshwater alluvial plain bestrode by low energy, meandering rivers, minor lakes and mires. Infrequent, scouring flood events were part of a multi-year cycle of drier and wetter years. The heavily vegetated flood plains supported abundant large herbivores. This was the final infilling of the great Eromanga Basin.
