Authors: Rajendaran Elayarasan , Zaini Muhammad Abbas Ahmad , Arsad Agus , Nasri Noor Shawal
Published: April 2019

Carbon-based adsorbents were prepared from used rubber slipper through steam and potassium hydroxide activation for methylene blue removal. The materials were characterized for thermal decomposition, surface functional groups and specific surface area. Adsorbent prepared through potassium hydroxide activation shows a greater surface area of 76.2 m2/g and a higher maximum adsorption capacity of 60.2 mg/g. The steam-activated adsorbent displays a reasonably good adsorption capacity of 24 mg/g despite its trivial surface area of 0.543 m2/g. The equilibrium and kinetics data fitted well with the Langmuir and pseudo-kinetics models, respectively. The used rubber slipper is a promising adsorbent candidate for dye removal from water.

Authors: Oh Jong Ho , Bae Jin Ho , Kim Jeong Hyeon , Kim Seul Kee , Lee Jae Myung
Published: April 2019

Kevlar-polyurethane foam (PUF) was manufactured by adding Kevlar pulp, which has excellent mechanical strength and thermal performance, to PUF for the purpose of improving the performance of existing PUF. The mechanical strength of Kevlar-PUF was evaluated for each weight ratio (0.2, 0.4, 0.6, 0.8, and 1.0 wt.%) of fiber, as the performance of PUF was improved by the addition of Kevlar fiber. Compression tests were carried out at four temperatures (20, −50, −110, and −163 °C) in consideration of the service environment, where Kevlar-PUF is used as insulation of LNG storage systems. The fracture characteristics of the compressed specimen are also analyzed. The thermal conductivity of the foam at room temperature (20 °C) and low temperature (−20 °C) is measured according to the weight ratios. The addition of a certain amount of Kevlar fibers increases the compression resistance of PUF and improves the properties of the material.
Plant vascular system-feeding Psyllidae (Hemiptera) and Nematoda genomes encode family 12 glycosyl hydrolases
Authors: Jones Richard W.
Published: April 2019

Insect-encoded cellulolytic plant cell wall hydrolases have thus far been found mostly from glycosyl hydrolase family 5, 9, 10, and 45. We now report the first evidence for genomic encoding of family 12 glycosyl hydrolases in vascular feeding Psyllidae (Hemiptera) and Nematoda. The genes were identified in three psyllids (Acanthocasuarina muellerianaeTaylor,Pachypsylla venusta(Osten-Sacken), andDiaphorina citriKuwayama) and a root tip feeding dagger nematode (Xiphinema indexThorne and Allen; Dorylaimida: Longidoridae). While the final gene products were highly similar, the genomic intron structure varied, having a 2 kB intron inP. venusta, a 283 base-pair intron inD. citri, and no intron inX. index. Endoglucanase activity was demonstrated using theD. citrigenes in anAgrobacteriumConn (Rhizobiaceae) infiltration-based plant expression system. The presence of family 12 endoglucanases in this set of insects suggests a specific role in facilitating feeding on vascular tissue.
Trauma Induces Emergency Hematopoiesis through IL-1/MyD88–Dependent Production of G-CSF

Published: April 2019

The inflammatory response to infection or injury dramatically increases the hematopoietic demand on the bone marrow to replace effector leukocytes consumed in the inflammatory response. In the setting of infection, pathogen-associated molecular patterns induce emergency hematopoiesis, activating hematopoietic stem and progenitor cells to proliferate and produce progeny for accelerated myelopoiesis. Sterile tissue injury due to trauma also increases leukocyte demand; however, the effect of sterile tissue injury on hematopoiesis is not well described. We find that tissue injury alone induces emergency hematopoiesis in mice subjected to polytrauma. This process is driven by IL-1/MyD88–dependent production of G-CSF. G-CSF induces the expansion of hematopoietic progenitors, including hematopoietic stem cells and multipotent progenitors, and increases the frequency of myeloid-skewed progenitors. To our knowledge, these data provide the first comprehensive description of injury-induced emergency hematopoiesis and identify an IL-1/MyD88/G-CSF–dependent pathway as the key regulator of emergency hematopoiesis after injury.
Report on the 2018 Cancer, Autoimmunity, and Immunology Conference
Authors: Curran Colleen S. , Sommers Connie L. , Young Howard A. , Bourcier Katarzyna , Mancini Marie , Sharon Elad
Published: April 2019

With the increased use of cancer immunotherapy, a number of immune-related adverse events (irAEs) are being identified. These irAEs can be compared with known autoimmune disorders in similar tissues, with important similarities and differences. Understanding the etiology of irAEs may bring to light concepts applicable to immune responses in cancer, autoimmunity, and infectious disease. This immunobiology is especially relevant to cancer patients with preexisting allogeneic transplants or autoimmune disease who are undergoing cancer immunotherapy. To address these facets of cancer immunotherapy, academic leaders from these various disciplines discussed current irAE basic and clinical research, irAE diagnosis and management, and the need for biomarkers and algorithms to identify individuals at risk for irAEs at a conference jointly sponsored by the National Cancer Institute, National Institute of Allergy and Infectious Diseases, and National Institute of Arthritis and Musculoskeletal and Skin Diseases in Bethesda, MD, on March 22–23, 2018. Mechanisms and models to characterize irAEs, standardize protocols, store biospecimens, and capture and analyze irAE data were also reviewed during the inaugural Cancer, Autoimmunity, and Immunology Conference. This summary highlights cancer immunotherapy–induced irAEs, the challenges ahead, and the opportunities for greater understanding of autoimmune conditions.
Understanding Beverage Taxation: Perspective on the Philadelphia Beverage Tax's Novel Approach
Authors: Kane Ryan M. , Malik Vasanti S.
Published: April 2019

Despite the growing global trend of sugar-sweetened beverage (SSB) taxes for their potential as an untapped source of revenue and as a public health boon, these legislative efforts remain controversial. Multiple articles have reviewed this trend in recent years from modeling of long-term impacts to short-term empirical studies, yet most comprehensive, long-term health impact assessments remain forthcoming. These multi-faceted efficacy studies combined with case-based assessments of the policy process, descriptive pieces highlighting unique features of the policy and reflective perspectives targeting unanswered questions create a comprehensive body of literature to help inform present and future legislative efforts. The passage of the Philadelphia Beverage tax required a mix of political entrepreneurs, timing and context; while uniquely employing a nonpublic health frame, specific earmarking and a broadened scope with the inclusion of diet beverages. This perspective on the Philadelphia Beverage Tax will describe the passage and novel features of the Philadelphia Beverage Tax with a discussion of the ethical questions unique to this case.
Domains for Dirac–Coulomb min-max levels
Authors: Esteban Maria J. , Lewin Mathieu , Séré Éric
Published: April 2019

We consider a Dirac operator in three space dimensions, with an electrostatic (i.e., real-valued) potential

V(x)

, having a strong Coulomb-type singularity at the origin. This operator is not always essentially self-adjoint but admits a distinguished self-adjoint extension

D_V

. In a first part we obtain new results on the domain of this extension, complementing previous works of Esteban and Loss. Then we prove the validity of min-max formulas for the eigenvalues in the spectral gap of

D_V

, in a range of simple function spaces independent of

V

. Our results include the critical case lim inf

_{x \to 0} |x| V(x)= -1

, with units such that

\hbar=mc^2=1

, and they are the first ones in this situation. We also give the corresponding results in two dimensions.
The global diabatic circulation of the stratosphere as a metric for the Brewer–Dobson circulation
Authors: Linz Marianna , Abalos Marta , Glanville Anne Sasha , Kinnison Douglas E. , Ming Alison , Neu Jessica L.
Published: April 2019

Abstract. The circulation of the stratosphere, also known as the Brewer–Dobson
circulation, transports water vapor and ozone, with implications for
radiative forcing and climate. This circulation is typically quantified from
model output by calculating the tropical upwelling vertical velocity in the
residual circulation framework, and it is estimated from observations by
using time series of tropical water vapor to infer a vertical velocity.
Recent theory has introduced a method to calculate the strength of the global
mean diabatic circulation through isentropes from satellite measurements of
long-lived tracers. In this paper, we explore this global diabatic
circulation as it relates to the residual circulation vertical velocity,
stratospheric water vapor, and ozone at interannual timescales. We use a
comprehensive climate model, three reanalysis data products, and satellite
ozone data. The different metrics for the circulation have different
properties, especially with regards to the vertical autocorrelation. In the
model, the different residual circulation metrics agree closely and are well
correlated with the global diabatic circulation, except in the lowermost
stratosphere. In the reanalysis products, however, there are more differences
throughout, indicating the dynamical inconsistencies of these products. The
vertical velocity derived from the time series of water vapor in the tropics
is significantly correlated with the global diabatic circulation, but this
relationship is not as strong as that between the global diabatic circulation
and the residual circulation vertical velocity. We find that the global
diabatic circulation in the lower to middle stratosphere (up to 500 K) is
correlated with the total column ozone in the high latitudes and in the
tropics. The upper-level circulation is also correlated with the total column
ozone, primarily in the subtropics, and we show that this is due to the
correlation of both the circulation and the ozone with upper-level
temperatures.
RH and O3 concentration as two prerequisites for sulfate formation
Authors: Fang Yanhua , Ye Chunxiang , Wang Junxia , Wu Yusheng , Hu Min , Lin Weili , Xu Fanfan , Zhu Tong
Published: April 2019

Abstract. Sulfate formation mechanisms have been discussed extensively but are still disputed. In this work, a year-long particulate matter (PM2.5) sampling campaign was conducted together with measurements of gaseous pollutant concentrations and meteorological parameters in Beijing, China, from March 2012 to February 2013. The sulfur oxidation ratio (SOR), an indicator of secondary sulfate formation, displayed a clear summer peak and winter valley, even though no obvious seasonal variations in sulfate mass concentration were observed. A rapid rise in the SOR was found at a RH threshold of ~ 45 % or an O3 concentration threshold of ~ 35 ppb, suggesting that RH and O3 concentrations were two prerequisites for rapid sulfate formation, which likely occurred via multiphase reactions. H2O2 oxidation was proposed to be the major route of sulfate formation, since the O3 oxidation route has previously been shown to be unimportant. The seasonal variations in sulfate formation could be accounted for by variations in the RH and O3 prerequisites. For example, over the year-long study, the fastest SO2-to-sulfate conversion occurred in summer, which was associated with the highest values of both O3 concentration and RH. The SOR also displayed variations with pollution levels, i.e., the SOR increased as pollution evolved in all seasons. Such variations were primarily associated with a transition from the slow gas phase formation of sulfate to rapid multiphase reactions, since RH increased as pollution evolved. In addition, the self-catalytic nature of sulfate formation (i.e., increasing aerosol water content with simultaneous increases in sulfate mass concentrations and RH) also contributed to variations among the pollution scenarios. Overall, our observations validated the two prerequisites for fast sulfate formation and revealed the seasonal and pollution level variations in sulfate formation in Beijing. H2O2 oxidation was the major route of sulfate formation, although reactions involving transition metal ions (TMIs) and NO2 might have also competed.
The OCO-3 mission: measurement objectives and expected performance based on 1 year of simulated data
Authors: Eldering Annmarie , Taylor Thomas E. , O'Dell Christopher W. , Pavlick Ryan
Published: April 2019

Abstract. The Orbiting Carbon Observatory-3 (OCO-3) is NASA's next instrument dedicated to extending the record of
the dry-air mole fraction of column carbon dioxide (XCO2) and solar-induced fluorescence (SIF) measurements from space.
The current schedule calls for a launch from the Kennedy Space Center no earlier than April 2019 via a Space-X Falcon 9 and Dragon capsule.
The instrument will be installed as an external payload on the Japanese Experimental Module Exposed Facility (JEM-EF)
of the International Space Station (ISS) with a nominal mission lifetime of 3 years.
The precessing orbit of the ISS will allow for viewing of the Earth at all latitudes less than approximately 52∘,
with a ground repeat cycle that is much more complicated than the polar-orbiting satellites
that so far have carried all of the instruments capable of measuring carbon dioxide from space. The grating spectrometer at the core of OCO-3 is a direct copy of the OCO-2 spectrometer,
which was launched into a polar orbit in July 2014.
As such, OCO-3 is expected to have similar instrument sensitivity and performance characteristics to OCO-2,
which provides measurements of XCO2 with precision better than 1 ppm
at 3 Hz, with each viewing frame containing eight footprints approximately 1.6 km by 2.2 km in size.
However, the physical configuration of the instrument aboard the ISS, as well as the use of a new pointing mirror assembly (PMA),
will alter some of the characteristics of the OCO-3 data compared to OCO-2.
Specifically, there will be significant differences from day to day in the sampling locations and time of day.
In addition, the flexible PMA system allows for a much more dynamic observation-mode schedule. This paper outlines the science objectives of the OCO-3 mission and, using a simulation of 1 year of global observations,
characterizes the spatial sampling, time-of-day coverage, and anticipated data quality of the simulated L1b.
After application of cloud and aerosol prescreening, the L1b radiances are run through the operational L2 full physics retrieval algorithm,
as well as post-retrieval filtering and bias correction,
to examine the expected coverage and quality of the retrieved XCO2 and to show how the measurement objectives are met.
In addition, results of the SIF from the IMAP–DOAS algorithm are analyzed.
This paper focuses only on the nominal nadir–land and glint–water observation modes,
although on-orbit measurements will also be made in transition and target modes, similar to OCO-2,
as well as the new snapshot area mapping (SAM) mode.
Multi-channel coupling of decay instability in three-dimensional low-beta plasma
Authors: Comişel Horia , Narita Yasuhito , Motschmann Uwe
Published: April 2019

Abstract. Three-dimensional hybrid simulations have been carried out to verify the hypothesis of simultaneous multi-channel decay of a large-amplitude Alfvén wave in a low-beta plasma, e.g., in the shock-upstream region or the solar corona. Obliquely-propagating daughter modes are excited along the perpendicular direction to the mean magnetic field at the same parallel wavenumbers and frequencies with the daughter modes driven by the field-aligned decay. We find that the transversal spectrum of waves is controlled by the multi-channel coupling of the decay process in low-beta plasmas and originates in the dispersion state of the shear Alfvén wave.
Rainfall intensity bursts and the erosion of soils: an analysis highlighting the need for high temporal resolution rainfall data for research under current and future climates
Authors: Dunkerley David L.
Published: April 2019

Abstract. Many land surface processes, including splash dislodgment and downslope transport of soil
materials, are influenced strongly by short-lived peaks in rainfall intensity
but are less well accounted for by longer-term average rates. Specifically,
rainfall intensities reached over periods of 10–30 min appear to have more
explanatory power than hourly or longer-period data. However, most analyses
of rainfall, and particularly scenarios of possible future rainfall extremes
under climate change, rely on hourly data. Using two Australian pluviograph
records with 1 s resolution, one from an arid and one from a wet tropical
climate, the nature of short-lived “intensity bursts” is analysed from the raw
inter-tip times of the tipping bucket gauges. Hourly apparent rainfall
intensities average just 1.43 mm h−1 at the wet tropical site and
2.12 mm h−1 at the arid site. At the wet tropical site, intensity
bursts of extreme intensity occur frequently, those exceeding
30 mm h−1 occurring on average at intervals of <1 d and those of
>60 mm h−1 occurring on average at intervals of <2 d. These
bursts include falls of 13.2 mm in 4.4 min, the equivalent of
180 mm h−1, and 29 mm in 12.6 min, equivalent to 138 mm h−1.
Intensity bursts at the arid site are much less frequent, those of
50–60 mm h−1 occurring at intervals of ∼1 month; moreover, the
bursts have a much shorter duration. The aggregation of rainfall data to
hourly level conceals the occurrence of many of these short-intensity bursts,
which are potentially highly erosive. A short review examines some of the
mechanisms through which intensity bursts affect infiltration, overland flow,
and soil dislodgment. It is proposed that more attention to resolving these
short-lived but important aspects of rainfall climatology is warranted,
especially in light of possible changes in rainfall extremes under climate
change.

Abstract. This study focuses on the Iberian Peninsula and investigates the propagation
of precipitation uncertainty, and its interaction with hydrologic modeling,
in global water resource reanalysis. Analysis is based on ensemble
hydrologic simulations for a period spanning 11 years (2000–2010). To
simulate the hydrological variables of surface runoff, subsurface runoff,
and evapotranspiration, we used four land surface models (LSMs) – JULES (Joint UK
Land Environment Simulator), ORCHIDEE (Organising Carbon and Hydrology In
Dynamic Ecosystems), SURFEX (Surface Externalisée), and HTESSEL
(Hydrology – Tiled European Centre for
Medium-Range Weather Forecasts – ECMWF – Scheme for Surface Exchanges over Land) – and one
global hydrological model, WaterGAP3 (Water – a Global Assessment and
Prognosis). Simulations were carried out for five precipitation
products – CMORPH (the Climate Prediction Center
Morphing technique of the National Oceanic and Atmospheric Administration,
or NOAA), PERSIANN (Precipitation Estimation from Remotely Sensed Information using Artificial
Neural Networks), 3B42V(7), ECMWF reanalysis, and a machine-learning-based blended product. As a reference, we used a ground-based
observation-driven precipitation dataset, named SAFRAN, available at
5 km, 1 h resolution. We present relative performances of hydrologic
variables for the different multi-model and multi-forcing scenarios. Overall,
results reveal the complexity of the interaction between precipitation
characteristics and different modeling schemes and show that uncertainties
in the model simulations are attributed to both uncertainty in precipitation
forcing and the model structure. Surface runoff is strongly sensitive to
precipitation uncertainty, and the degree of sensitivity depends
significantly on the runoff generation scheme of each model examined.
Evapotranspiration fluxes are comparatively less sensitive for this study
region. Finally, our results suggest that there is no single model–forcing
combination that can outperform all others consistently for all variables
examined and thus reinforce the fact that there are significant benefits to
exploring different model structures as part of the overall modeling
approaches used for water resource applications.
A failed attempt at developing a search filter for systematic review methodology articles in Ovid Embase
Authors: Neilson Christine , Lê Mê-Linh
Published: April 2019

Objectives: This paper describes the development, execution, and subsequent failure of an attempt to create an Ovid Embase search filter for locating systematic review methodology articles.Methods: The authors devised a work plan, based on best practices, for search filter development that has been outlined in the literature. Three reference samples were gathered by identifying the OVID Embase records for specific articles that were included in the PubMed Systematic Review Methods subset. The first sample was analyzed to develop a set of keywords and subject headings to include in the search filter. The second and third samples would have been used to calibrate the search filter and to calculate filter sensitivity and precision, respectively.Results: Technical shortcomings, database indexing practices, and the fuzzy nature of keyword terminology relevant to the topic prevented us from designing the search filter.Conclusion: Creating a search filter to identify systematic review methodology articles in Ovid Embase is not possible at this time.
Searching by grant number: comparison of funding acknowledgments in NIH RePORTER, PubMed, and Web of Science
Authors: Powell Kimberly
Published: April 2019

Objective: Several publication databases now index the associated funding agency and grant number metadata with their publication records. Librarians who are familiar with the particulars of these databases can assist investigators and administrators with data gathering for publication summaries and metrics required for renewals of and progress reports for National Institutes of Health (NIH) grants.Methods: Publication lists were pulled from three main indexers of publication-associated funding information (NIH RePORTER, PubMed, and Web of Science), using iterative search strategies. All discovered variations for the cited grant number of interest were recorded and tested. Publication lists were compared for overall coverage.Results: A total of 986 publications citing the single grant number of interest were returned from the given time frame: 920 were found in PubMed, 860 in NIH RePORTER, and 787 in Web of Science. Web of Science offered the highest percentage of publications that were not found in the other 2 sources (n=63). Analysis of publication funding acknowledgments uncovered 21 variations of the specific NIH award of interest that were used to report funding support.Conclusions: This study shows that while PubMed returns the most robust list of publications, variations in the format of reported funding support and indexing practices meant no one resource was sufficient to capture all publications that cited a given NIH project grant number. Librarians looking to help build grant-specific publication lists will need to use multiple resources and be aware of the most frequently reported grant variations to identify a comprehensive list of supported publications. This article has been approved for the Medical Library Association’s Independent Reading Program.
A partnership between academic and public librarians: “What the Health” workshop series
Authors: Koos Jessica A. , Saragossi Jamie , Stevens Gregg A. , Filosa Salvatore
Published: April 2019

Background: Public librarians are in a unique position to assist the general public with health information inquiries. However, public librarians might not have the training, detailed knowledge, and confidence to provide high-quality health information.Case Presentation: The authors created and delivered three workshops to public librarians in Suffolk County, New York, highlighting several National Library of Medicine resources. Each workshop focused on a different topic: general consumer health resources, genetics health resources, and environmental/toxicology resources. At the end of each workshop, participants were asked to complete the Training Session Evaluation form provided by the National Network of Libraries of Medicine (NNLM). All participants reported that they learned a new skill or about a new tool, that their ability to locate online health information improved, and that they planned to use the knowledge they gained in the future. Online tutorials covering the major resources from each workshop were created and made accessible to the public on several organizations’ websites. Virtual reference services were initiated for public librarians who need further assistance with these resources and will continue to be provided on an ongoing basis. Financial support for the equipment and software utilized in each of these tasks was provided by NNLM.Conclusions: Based on attendance and participant feedback, this model of health information outreach appears to have been successful in furthering the educational needs of public librarians and may be useful to others in creating a similar program in their communities.

Authors: Iqbal Saira , Siddiqui Danish Ahmed
Published: April 2019

This study examined the impact of Deceptive Advertising on Customer Loyalty in the telecommunication industry of Karachi, Pakistan. This research was quantitative in nature. The sample size was 250; questionnaires were distributed electronically and manually. Exploratory Factor Analysis (EFA) was used to analyze the data with the help of SPSS. Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM) using AMOS, conducted to ensure the model and testing the hypothesis. The outcome of the present study verifies that word of mouth has a strong significant influence on customer loyalty. Hence customer satisfaction and customer trust are causing word of mouth in a positive and significant way. So it shows that there is a positive and strongly significant influence of customer satisfaction and trust on customer loyalty with the mediation of word of mouth. On the other hand, deceptive ads are causing word of mouth in a negative way. Hence it is concluded that deceptive ads have a negative influence on customer loyalty with the mediation of word of mouth. This study suggested that in order to increase customer loyalty and build a long-term relationship with the customer’s telecom companies should focus on accurate information and rendering the level of competitive services to their customers.
Words Matter
Authors: Constable Marianne
Published: April 2019

The disregard of language and the breakdown of the distinction between reality and appearance that characterize the Trump era not only are symptomatic of a loss of language and of politics, but also reveal an extreme nihilism that is worthy of question and thought. No less a philosopher-rhetorician than Friedrich Nietzsche offers us a diagnosis of this condition, most pithily in the six-moment history of Western philosophy that he presents in Twilight of the Idols. For Nietzsche, after the end of the history of the error of reason comes a joyous overcoming of nihilism. Nietzsche's critics, however, are not so sure.
Stasis in the Net of Affect
Authors: Matheson Calum
Published: April 2019

Stasis is a precondition for debate that can be understood as a proposition determining controversy in advance or a retroactively determined basis for judgment. This essay examines the affective conditions of possibility for stasis, arguing that the propositional model risks concealing a broader economy of desire that might help to explain why unexpected audiences cathect to certain positions. The example of support for Donald Trump from QAnon conspiracy theorists illustrates these affective connections and the importance of reexamining affect as a condition of possibility for debate.

Authors: Trasolini Nicholas , Kang Hyunwoo , Carney John , Rounds Alexis , Murrietta Adam , Marecek Geoffrey S.
Published: April 2019

Introduction:

We sought to characterize the prevalence of methamphetamine (MA) abuse and associated orthopaedic injury patterns at our level 1 trauma center.

Methods:

We conducted a retrospective review of all orthopaedic consults for the year 2016. Patients were classified as MA users based on urine toxicology results and social history.

Results:

The prevalence of MA use was 10.0%. MA users were more likely to present with hand lacerations and other infections (P < 0.05 for all). Regarding the mechanism of injury, MA users were more likely to be involved in automobile versus pedestrian, automobile versus bicycle, ballistic, knife, closed fist, other assault/altercation, and animal bite injuries (P < 0.05 for all).

Discussion:

MA use is prevalent at our level 1 trauma center. The prevalence and injury patterns of MA abuse warrant deeper study into the effects of this drug on orthopaedic outcomes.

Students’ Perceptions Towards the Benefits and Drawbacks of EMI Classes
Authors: Phuong Yen H. , Nguyen Thong T.
Published: April 2019

Globalization and internationalization have fostered the development of English as a medium of instruction (EMI). EMI is gaining its popularity all over the world. In line with this tendency, various universities in Vietnam introduce EMI to its undergraduate programs in forms of advanced or high-quality training programs. However, little research has been conducted to discover the benefits as well as drawbacks of these EMI programs, especially in context where English is not a second language nor popularly used outside the classroom as in Vietnam. The purpose of this study was therefore conducted to explore the issue in a university in Vietnam. A group of 136 sophomores majoring in International Business and Information Technology participated in this study. A questionnaire was administered to them to obtain quantitative data. Six students were selected randomly to take part in individual interviews to obtain qualitative data. Results indicated that students perceived four clusters of benefits and drawbacks that EMI classrooms provide.

OBJECTIVE: The study investigated attitude to ageing as a predictor of subjective health and quality of life among the older people in Ika South Local Government Area, Delta State. Three research questions guided the study.

METHOD: The population of the study comprised 6,670 older people 3,323 males and 3347 females in Ika South Local Government Area of Delta State. The sample size of the study is 667 older people in Ika South Local Government Area of Delta State. A multi-stage random sampling technique was used to get the sample size for the study. Two stages of selection were used in order to draw the sample for the study. For the first stage, simple sampling technique was used to draw 11 communities out of 22 communities in the study area. In second stage 10% of the study population was used. The questionnaires were validated by two experts from guidance and counselling and one from measurement and evaluation. Reliability of the instrument was determined using Cronbach Alpha method reliability estimate. Copies of the questionnaire were administered directly to the respondents. Linear regression was used for the data analysis.

RESULTS: The finding of the study revealed that older people of Ika South Local Government Area maintains positive attitude to ageing, that attitude to ageing is not a predictor of subjective health among older people of Ika South Local Government Area and attitude to ageing does not significantly predict quality of life among people of Ika South Local Government Area.

CONCLUSION: Based on the finding of the study, government and professional guidance counsellors should make use of the information generated from the study to organize workshop training for older people on what constitute subjective health quality of life and what constitute positive attitude to ageing. 
The Impact of Higher Education Expansion Policy on the Wage of College Graduates in China
Authors: Ma Xinxin
Published: April 2019

Using a longitudinal survey data conducted from 1997 to 2011, this study employs an empirical study to provide evidence about the impact of the higher education expansion policy on the wage levels of college graduates in China. Major conclusions emerge. First, in general, the higher education expansion policy does not affect the wage level of young college graduates. Second, the difference of policy impact on wage by various wage percentiles is small. Third, the policy decreases the wage level of new college graduates in a short term and the negative effect disappears in a long term. Fourth, to consider the group heterogeneities of policy impacts, it is shown that both the differences between the Eastern, Central and Western Region groups and the gender gaps are small, whereas the policy impact differ by the urban and rural groups.

DETERMINANTS OF INCREASING HOUSEHOLD SAVINGS IN POLAND
Authors: Wierzbicka Ewa
Published: April 2019

Research carried out, among others ordered by the Polish Bank Association, indicate untapped potential savings for Polish society. The aim of the article is to present the reasons for a low propensity to save households, as well as to identify factors and motives that decide about saving, and to suggest directions for actions to increase the propensity to save, especially long-term. The author limits her considerations to voluntary savings of households, not responding to the compulsory saving for pension purposes resulting from the social insurance system. Accumulation of savings is of great importance not only at the micro level but also for the
entire economy, because it is internal, domestic source of financial capital. Long-term savings, which stabilize the financial system and may have an impact on reducing the costs of servicing public debt and changing its structure, limiting the participation of foreign investors, are particularly important. The greater the propensity to save, the more national resources may beminvested in the polish economy. Moreover, the shortage of domestic savings is not only a serious challenge for bank risk management due to the need to top up the missing domestic capital with foreign funds. The deficiency of domestic savings in relation to the needs of the economy and the state also increases the systemic risk of the national economy and country.

 A Delphi study of teachers views on engagement in the science classroom
Authors: Abrahamsson Cristian , Malmberg Claes , Pendrill Ann-Marie

What happens in a science classroom where students are engaged and how do teachers observe and interpret student engagement? This article highlights teachers’ perspective on students’ engagement in science education and to what extent it is connected to the scientific content. This approach complements earlier research which focuses mostly on students’ attitude towards science education and their interest in various topics in science.The findings are based on a three-stage Delphi survey distributed to 39 expert science teachers. The results shows science education with a range of different perspectives and that most teachers do not perceive any direct connection between specific science topics and the students’ engagement. The survey also shows that teachers to a high level interpret students’ emotional expressions and academic behavior as engagement rather than their cognitive behavior.
Uterine sarcoma: a clinical case and a literature review
Authors: Bužinskienė Diana , Mikėnas Saulius , Drąsutienė Gražina , Mongirdas Matas
Published: April 2019

Background. Uterine sarcomas are rare gynaecologic tumours representing 3–7% of all uterine malignancies. The aetiology of sarcomas is still unclear: it is thought, that chromosomal translocations have influence on wide histological variety of sarcomas. Presenting symptoms are vague and nonspecific. Usually sarcoma causes abnormal vaginal bleeding, can cause abdominal or pelvic pain, or manifests as a rapidly growing uterine tumour. The diagnosis of sarcoma is often made retrospectively after surgical removal of a presumed benign uterine neoplasm, because imaging modalities such as ultrasound, computed tomography, or magnetic resonance imaging cannot yet accurately and reliably distinguish between benign leiomyoma and malignant pathology. If there are certain clinical features that raise a suspicion of malignancy in the uterus, it is recommended to avoid the use of power morcellation through laparoscopic surgery in order to prevent disease dissemination.
Materials and methods. We present a clinical case of a 64-year-old patient, who was referred to hospital due to abdominal pain and tenesmus that lasted for two days. From a past medical history it was known that previously the patient had been diagnosed with uterine myoma. Transvaginal ultrasonography showed a 10.4 cm × 9.8 cm uterine tumour of nonhomogeneous structure with signs of necrosis and good vascularization. The patient refused urgent hysterectomy, that was advised to her. The patient was operated on one month later and total hysterectomy with bilateral salpingooforectomy was performed. Postoperative histological evaluation showed undifferentiated sarcoma uterus pT1b L/V0. Imaging modalities were made to evaluate possible dissemination of the disease. In the absence of signs of disease progression, the patient received radiotherapy and brachytherapy and was followed-up by doctors.
Results and conclusions. Uterine sarcomas are highly malignant tumours that originate from smooth muscles and connective tissue elements of the uterus and make up 1% of all malignant gynaecological tumours and about 3–7% of all malignant uterine tumours. Imaging modalities cannot yet reliably distinguish benign myomas from malignant sarcomas. It is important not to damage the wholeness of uterus during operation in order to prevent dissemination of the disease in the abdominal cavity. The low-grade endometrial stromal sarcoma has the best survival prognosis, while carcinosarcoma and undifferentiated uterine sarcoma have the lowest survival rates.
Réévaluer la place de l’Aquitaine dans le tourisme de mémoire transatlantique (France, Québec, Acadie) : des voyages des associations de familles-souches aux circuits patrimoniaux
Authors: Cherubini Bernard
Published: April 2019

L’Aquitaine est restée en retrait de la dynamique des échanges entre la France et le Québec, et avec l’Acadie, lors des commémorations de la fondation de l’Acadie en 2004 et de Québec en 2008, tandis que la région Poitou-Charentes impulsait de nouveaux projets patrimoniaux et de mise en valeur touristique des lieux de mémoire. Concevoir un circuit touristique rural ou urbain au-delà d’une ligne Royan-Angoulême présente toutefois l’avantage d’ouvrir un débat riche d’échanges, d’idées et de confrontations au sein des milieux professionnels du tourisme, du patrimoine et de l’inventaire des lieux de mémoire, peu concernés jusqu’à présent par les migrations des familles souches vers la Nouvelle-France. La ville de Bordeaux vient toutefois de créer les « Chemins du Québec à Bordeaux ». De possibles extensions de ces circuits patrimoniaux en direction du Blayais et de la vallée de la Dordogne sont aussi envisagées, à l’image de ceux du Béarn, autour du baron de Saint-Castin. L’ingénierie des chemins de mémoire doit pouvoir profiter de l’impulsion apportée par les rassemblements de familles-souches, par le développement d’un tourisme domestique intéressé par les collectes de mémoire, du patrimoine culturel immatériel.
Le point de vue des parents sur les interactions avec l’enseignant·e : développement d’un questionnaire s’appuyant sur le modèle circomplexe
Authors: Fahrni Laurent , Genoud Philippe A.
Published: April 2019

Cet article présente le développement d’un questionnaire évaluant, du point de vue des parents, leurs interactions avec l’enseignant·e de leur enfant. Le modèle sous-jacent s’inscrit dans la lignée des travaux sur les relations interindividuelles basées sur le circomplexe. La démarche prend en compte les caractéristiques spécifiques de ce type de modèle et confirme la présence de huit dimensions (pour 32 items au total) : directivité, soutien, empathie, partage, incertitude, insatisfaction, agressivité et prescription. Les différents résultats donnent une image probante des qualités psychométriques de cet instrument ainsi que la possibilité de réduire les dimensions à quatre facteurs plus généraux. Le questionnaire étant disponible en annexe, des pistes et des recommandations d’utilisation sont discutées.
Portrait du développement orthographique en arabe de jeunes enfants du préscolaire scolarisés au Québec
Authors: Ahmed Doaa Mohammad Hamdan , Montésinos-Gelet Isabelle , Charron Annie
Published: April 2019

Cette étude de cas multiples vise à décrire le développement de l’orthographe lexicale en arabe chez de jeunes enfants arabophones du préscolaire scolarisés au Québec (N = 9). À quatre reprises, les enfants ont été individuellement invités à une épreuve d’orthographes approchées, et ce, à partir d’un entretien semi-dirigé enregistré par vidéo. L’analyse des productions écrites réalisées nous a permis d’observer trois préoccupations des scripteurs : visuographiques, phonologiques et orthographiques. Les enfants se sont approprié l’écrit en exprimant une capacité à produire conventionnellement les phonogrammes, à combiner les syllabes au sein d’un mot, à ne pas avoir recours à un traitement exclusif des voyelles ou des consonnes et à respecter le schéma de mise en page de façon conventionnelle. Toutefois, leurs écrits ont parfois témoigné de pseudolettres et de désordres inter et intrasyllabiques.
L’apport du modèle Exit-Voice-Loyalty à la compréhension de l’apprentissage organisationnel – le cas d’un hôpital public
Authors: Vallat David , Bertezene Sandra
Published: April 2019

Cet article propose d’utiliser le modèle d’Hirschman, Exit, Voice, Loyalty (EVL) comme grille de lecture de la lutte contre le déclin de l’organisation à travers la question suivante : comment le modèle EVL peut-il être mobilisé dans le cadre d’une réflexion stratégique autour de l’apprentissage organisationnel ? Pour répondre à la question, nous proposons deux configurations d’Exit, Voice, Loyalty ayant des conséquences opposées sur l’apprentissage organisationnel. La pertinence de ce modèle est discutée au regard de son application à l’apprentissage organisationnel. Nous confrontons ensuite ce modèle au terrain d’expérimentation, un hôpital public, avant d’en discuter les résultats.
Mécénat d’entreprise : un dispositif de gestion entre intérêts, passions et politique
Authors: Petitprêtre Benoît , Lauthier Estelle
Published: April 2019

L’objectif de ce papier est de s’appuyer sur le travail d’Albert O. Hirschman (AOH) pour éclairer le mécénat d’entreprise. En effet il nous semble que ce domaine est peu investigué par la recherche francophone en gestion et lorsque c’est le cas, elle a rabattu le mécénat sur la communication. Cette recherche s’appuie sur un travail auprès d’organisations françaises et sur les spécificités de ce contexte. Elle montre la diversité des motivations des mécènes qui doivent arbitrer entre leur préoccupation pour l’intérêt public et l’intérêt économique. Il illustre le fait que le mécénat est en lui-même créateur et porteur de sens pour l’entreprise et ses parties prenantes, qu’il doit se concevoir comme tel afin de dépasser les impasses d’une approche purement instrumentale, mais qu’il est également traversé par des débats politiques qui dépassent la simple technique.
