Coupling physically based and data-driven models for assessing freshwater inflow into the Small Aral Sea
Authors: Ayzel Georgy , Izhitskiy Alexander
Published: June 2018

Abstract. The Aral Sea desiccation and related changes in hydroclimatic conditions on a
regional level is a hot topic for past decades. The key problem of scientific
research projects devoted to an investigation of modern Aral Sea basin
hydrological regime is its discontinuous nature – the only limited amount of
papers takes into account the complex runoff formation system entirely.
Addressing this challenge we have developed a continuous prediction system
for assessing freshwater inflow into the Small Aral Sea based on coupling
stack of hydrological and data-driven models. Results show a good prediction
skill and approve the possibility to develop a valuable water assessment tool
which utilizes the power of classical physically based and modern machine
learning models both for territories with complex water management system and
strong water-related data scarcity. The source code and data of the proposed
system is available on a Github page

Evaluation of blue and green water resources in the upper Yellow River basin of China
Authors: Gao Xiaoxi , Zuo Depeng , Xu Zongxue , Cai Siyang , Xianming Han
Published: June 2018

Abstract. The total amount of water resources severely affects socioeconomic
development of a region or watershed, which means that accurate
quantification of the total amount of water resources is vital for the area,
especially for the arid and semi-arid regions. Traditional evaluation of
water resources only focused on the qualification of blue water, while the
importance of green water was not fully considered. As the second largest
river in China, the Yellow River plays an important role in socioeconomic
development of the Yellow River basin. Therefore, the blue and green water
resources in the upper Yellow River basin (UYRB) were evaluated by the SWAT
model in this study. The results show that the average annual total amount of
water resources in the UYRB was 140.5 billion m3, in which the blue
water resources is 37.8 billion m3, and green water resources is
107.7 billion m3. The intra-annual variability of the blue water and
green water is relatively similar during the same period. The higher
temperature, the greater difference between the blue and green water. The
inter-annual variability of the blue and green water shows that the trends in
precipitation, blue and green water have a relatively similar characteristic.
The spatial distribution of the blue and green water is characteristic with
gradually decreasing from the northwest to the southeast, and the blue water
around the main stream is greater than that in the other areas.
Multi-scale fluctuation analysis of precipitation in Beijing by Extreme-point Symmetric Mode Decomposition
Authors: Li Jiqing , Duan Zhipeng , Huang Jing
Published: June 2018

Abstract. With the aggravation of the global climate change, the shortage of water resources in China is becoming more and more serious. Using reasonable methods to study changes in precipitation is very important for planning and management of water resources. Based on the time series of precipitation in Beijing from 1951 to 2015, the multi-scale features of precipitation are analyzed by the Extreme-point Symmetric Mode Decomposition (ESMD) method to forecast the precipitation shift. The results show that the precipitation series have periodic changes of 2.6, 4.3, 14 and 21.7 years, and the variance contribution rate of each modal component shows that the inter-annual variation dominates the precipitation in Beijing. It is predicted that precipitation in Beijing will continue to decrease in the near future.
Predicting future land cover change and its impact on streamflow and sediment load in a trans-boundary river basin
Authors: Wang Jie , Wang Hao , Ning Shaowei , Hiroshi Ishidaira
Published: June 2018

Abstract. Sediment load can provide very important perspective on erosion of river basin. The changes of human-induced vegetation cover, such as deforestation or afforestation, affect sediment yield process of a catchment. We have already evaluated that climate change and land cover change changed the historical streamflow and sediment yield, and land cover change is the main factor in Red river basin. But future streamflow and sediment yield changes under potential future land cover change scenario still have not been evaluated. For this purpose, future scenario of land cover change is developed based on historical land cover changes and land change model (LCM). In addition, future leaf area index (LAI) is simulated by ecological model (Biome-BGC) based on future land cover scenario. Then future scenarios of land cover change and LAI are used to drive hydrological model and new sediment rating curve. The results of this research provide information that decision-makers need in order to promote water resources planning efforts. Besides that, this study also contributes a basic framework for assessing climate change impacts on streamflow and sediment yield that can be applied in the other basins around the world.

Published: June 2018

Abstract. Based on the evaluation of the present situation of water resources and the
development of water conservancy projects and social economy, optimal
allocation of regional water resources presents an increasing need in the
water resources management. Meanwhile it is also the most effective way to
promote the harmonic relationship between human and water. In view of the own
limitations of the traditional evaluations of which always choose a single
index model using in optimal allocation of regional water resources, on the
basis of the theory of variable fuzzy sets (VFS) and system dynamics (SD), an
integrated variable fuzzy sets model (IVFS) is proposed to address dynamically
complex problems in regional water resources management in this paper. The
model is applied to evaluate the level of the optimal allocation of regional
water resources of Zoucheng in China. Results show that the level of
allocation schemes of water resources ranging from 2.5 to 3.5, generally
showing a trend of lower level. To achieve optimal regional management of
water resources, this model conveys a certain degree of accessing water
resources management, which prominently improve the authentic assessment of
water resources management by using the eigenvector of level H.
Discussion on water resources value accounting and its application
Authors: Guo Biying , Huang Xiaorong , Ma Kai , Gao Linyun , Wang Yanqiu
Published: June 2018

Abstract. The exploration of the compilation of natural resources balance sheet has been proposed since 2013. Several elements of water resources balance sheet have been discussed positively in China, including basic concept, framework and accounting methods, which focused on calculating the amount of water resources with statistical methods but lacked the analysis of the interrelationship between physical volume and magnitude of value. Based on the study of physical accounting of water resources balance sheet, the connotation of water resources value is analyzed in combination with research on the value of water resources in the world. What's more, the theoretical framework, form of measurement and research methods of water resources value accounting are further explored. Taking Chengdu, China as an example, the index system of water resources balance sheet in Chengdu which includes both physical and valuable volume is established to account the depletion of water resources, environmental damage and ecological water occupation caused by economic and social water use. Moreover, the water resources balance sheet in this region which reflects the negative impact of the economy on the environment is established. It provides a reference for advancing water resources management, improving government and social investment, realizing scientific and rational allocation of water resources.
Distributed source pollutant transport module based on BTOPMC: a case study of the Laixi River basin in the Sichuan province of southwest China
Authors: Zhang Hongbo , Ao Tianqi , Gusyev Maksym , Ishidaira Hiroshi , Magome Jun , Takeuchi Kuniyoshi
Published: June 2018

Abstract. Nitrogen and phosphorus concentrations in Chinese river catchments
are contributed by agricultural non-point and industrial point sources
causing deterioration of river water quality and degradation of ecosystem
functioning for a long distance downstream. To evaluate these impacts, a
distributed pollutant transport module was developed on the basis of BTOPMC
(Block-Wise Use of TOPMODEL with Muskingum-Cunge Method), a grid-based
distributed hydrological model, using the water flow routing process of
BTOPMC as the carrier of pollutant transport due a direct runoff. The
pollutant flux at each grid is simulated based on mass balance of pollutants
within the grid and surface water transport of these pollutants occurs
between grids in the direction of the water flow on daily time steps. The
model was tested in the study area of the Lu county area situated in the
Laixi River basin in the Sichuan province of southwest China. The simulated
concentrations of nitrogen and phosphorus are compared with the available
monthly data at several water quality stations. These results demonstrate a
greater pollutant concentration in the beginning of high flow period
indicating the main mechanism of pollution transport. From these preliminary
results, we suggest that the distributed pollutant transport model can
reflect the characteristics of the pollutant transport and reach the expected
target.

Authors: Li Zhanjie , Yu Jingshan , Xu Xinyi , Sun Wenchao , Pang Bo , Yue Jiajia
Published: June 2018

Abstract. Hydrological models are important and effective tools for detecting complex hydrological processes. Different models have different strengths when capturing the various aspects of hydrological processes. Relying on a single model usually leads to simulation uncertainties. Ensemble approaches, based on multi-model hydrological simulations, can improve application performance over single models. In this study, the upper Yalongjiang River Basin was selected for a case study. Three commonly used hydrological models (SWAT, VIC, and BTOPMC) were selected and used for independent simulations with the same input and initial values. Then, the BP neural network method was employed to combine the results from the three models. The results show that the accuracy of BP ensemble simulation is better than that of the single models.
Trading the Economic Value of Unsatisfied Municipal Water Demand
Authors: Telfah Dua'a B. , Minciardi Riccardo , Roth Giorgio
Published: June 2018

Abstract. Modelling and optimization techniques for water resources
allocation are proposed to identify the economic value of the unsatisfied
municipal water demand against demands emerging from other sectors. While
this is always an important step in integrated water resource management
perspective, it became crucial for water scarce Countries. In fact, since
the competition for the resource is high, they are in crucial need to trade
values which will help them in satisfying their policies and needs. In this
framework, hydro-economic, social equity and environmental constraints need
to be satisfied. In the present study, a hydro-economic decision model based
on optimization schemes has been developed for water resources allocation,
that enable the evaluation of the economic cost of a deficiency in
fulfilling the municipal demand. Moreover, the model enables efficient water
resources management, satisfying the demand and proposing additional water
resources options. The formulated model is designed to maximize the demand
satisfaction and minimize water production cost subject to system
priorities, preferences and constraints. The demand priorities are defined
based on the effect of demand dissatisfaction, while hydrogeological and
physical characteristics of the resources are embedded as constraints in the
optimization problem. The application to the City of Amman is presented.
Amman is the Capital City of the Hashemite Kingdom of Jordan, a Country
located in the south-eastern area of the Mediterranean, on the East Bank of
the Jordan River. The main challenge for Jordan, that threat the development
and prosperity of all sectors, is the extreme water scarcity. In fact,
Jordan is classified as semi-arid to arid region with limited financial
resources and unprecedented population growth. While the easy solution
directly goes to the simple but expensive approach to cover the demand, case
study results show that the proposed model plays a major role in providing
directions to decision makers to orient their policies and strategies in
order to achieve sustainability of scarce water resources, satisfaction of
the minimum required demand as well as financial sustainability. In
addition, results map out national needs and priorities that are crucial in
understanding and controlling the complexity of Jordan's water sector,
mainly for the city of Amman.

Published: June 2018

Abstract. Sediment and runoff changes of seven hydrological
stations along the Lower Yellow River (LYR) (Huayuankou Station, Jiahetan
Station, Gaocun Station, Sunkou Station, Ai Shan Station, Qikou Station and
Lijin Station) from 1980 to 2003 were alanyzed at multiple time scale. The
maximum value of monthly, daily and hourly sediment load and runoff
conservations were also analyzed with the annually mean value. Mann–Kendall
non-parametric mathematics correlation test and Hurst coefficient method
were adopted in the study. Research results indicate that (1) the runoff of
seven hydrological stations was significantly reduced in the study period at
different time scales. However, the trends of sediment load in these
stations were not obvious. The sediment load of Huayuankou, Jiahetan and
Aishan stations even slightly increased with the runoff decrease. (2) The
trends of the sediment load with different time scale showed differences at
Luokou and Lijin stations. Although the annually and monthly sediment load
were broadly flat, the maximum hourly sediment load showed decrease trend.
(3) According to the Hurst coefficients, the trend of sediment and runoff
will be continue without taking measures, which proved the necessary of
runoff-sediment regulation scheme.
Evaluation of water productivity under climate change in irrigated areas of the arid Northwest China using an assemble statistical downscaling method and an agro-hydrological model
Authors: Liu Liu , Guo Zezhong , Huang Guanhua
Published: June 2018

Abstract. The Heihe River Basin (HRB) is the second largest inland river
basin, located in the arid region of Northwest China with a serious water
shortage. Evaluation of water productivity will provide scientific
implications for agricultural water-saving in irrigated areas of the arid
region under climate change. Based on observed meteorological data, 23 GCMs
outputs and the ERA-40 reanalysis data, an assemble statistical downscaling
model was developed to generate climate change scenarios under RCP2.6,
RCP4.5, RCP8.5 respectively, which were then used to drive the SWAP-EPIC
model to simulate crop growth in the irrigated areas of the middle HRB for
the future period from 2018 to 2047. Crop yield showed an increasing trend,
while crop water consumption decreased gradually in Gaotai and Ganzhou
irrigated areas. The water productivity in future 30 years showed an
increasing trend in both Gaotai and Ganzhou areas, with the most significant
increase under RCP4.5 scenario, which were both larger than 2 kg m−3.
Compared with that of the period from 2012 to 2015, the water productivity
during 2018–2047 under three RCP scenarios increased by 9.2, 14.3
and 11.8 % in the Gaotai area, and 15.4, 21.6, 19.9 % in the
Ganzhou area, respectively.
Estimating lake-water evaporation from data of large-aperture scintillometer in the Badain Jaran Desert, China, with two comparable methods
Authors: Han Peng-Fei , Wang Xu-Sheng , Jin Xiaomei , Hu Bill X.
Published: June 2018

Abstract. Accurate quantification of evaporation (E0) from open water is vital in
arid regions for water resource management and planning, especially for lakes
in the desert. The scintillometers are increasingly recognized by researchers
for their ability to determine sensible (H) and latent heat fluxes (LE)
accurately over distances of hundreds of meters to several kilometers, though
scintillometers are mainly used to monitor the land surface processes. In
this paper, it is installed on both sides of the shore over a lake. Compared
to the data of evaporationpan, the scintillometer was successfully applied to
Sumu Barun Jaran in Badain Jaran Desert using the classical method and the
proposed linearized β method. Due to the difficulty in measuring water
surface temperature and the easiness to monitor the water temperature at
different depths, it is worth thinking that if is feasible to utilize the
shallow water temperature instead of the water surface temperature and how
much errors it will cause. Water temperature at 10 and 20 cm depths were
used to replace the lakewater surface temperature in the two methods to
analyze the changes of sensible and latent heat fluxes in hot and cold
seasons at halfhour time scales. Based on the classical method, the values of
H were almost barely affected, and the average value of LE using water
temperature at 20 cm depth is 0.8–9.5 % smaller than that at 10 cm
depth in cold seasons. In hot seasons, compared to the results at 10 cm
depth, the average value of H increased by 20–30 %, and LE decreased
by about 20 % at 20 cm depth. In the proposed linearized β method
of scintillometer, only the slope of the saturation pressure curve (Δ)
is related to the water surface temperature, which was estimated using
available equations of saturated vapor pressure versus temperature of the
air. Compared to the values of estimated by the air temperature, while the
water surface temperature are replaced by water temperature at 10 and 20 cm
depths, in different seasons, the errors of 2–25 % in Δ were
caused. Thus was calculated by the original equation in the proposed
linearized β method of scintillometer. Interestingly, the water
temperature at 10 and 20 cm depths had little effect on H, LE (E0) in
different seasons. The reason is that the drying power of the air
(EA) accounted for about 85 % of the evaporation (i.e. the
changes of Δ have only about 3 % impact on evaporation), which
indicated that the driving force from unsaturated to saturated vapor pressure
at 2 m height (i.e. the aerodynamic portion) has the main role on
evaporation. Therefore, the proposed linearized β method of
scintillometer is recommended to quantify the H, LE (E0) over open
water, especially when the water surface temperature cannot be accurately
measured.
Application of remote sensing data for measuring freshwater ecosystems changes below the Zeya dam in the Russian Far East
Authors: Nikitina Oxana I. , Bazarov Kirill Y. , Egidarev Evgeny G.
Published: June 2018

Abstract. The large Zeya hydropower dam is located on the Zeya River, the largest
left-bank tributary of the Amur-Heilong River in Russia. The dam had been
constructed by 1980 and its operation has significantly transformed the flow
regime of the Zeya River. The flow regulation has reduced the magnitude of
periodic flooding of the floodplain areas located downstream from the Zeya
dam and disrupted habitats of flora and fauna. An estimation of the
transformation of the freshwater ecosystems is required to develop measures
necessary either to maintain or restore disrupted ecosystems. Application of
remote sensing methods allows measuring characteristics of the ecosystem's
components. Two sections of a floodplain below the Zeya dam were considered
for analysis in order to detect changes in objects at each site during the
comparison of remote data from 1969/1971 and 2016.
Understanding the potential sources and environmental impacts of dissolved and suspended organic carbon in the diversified Ramganga River, Ganges Basin, India
Authors: Khan Mohd Yawar Ali , Tian Fuqiang
Published: June 2018

Abstract. The river network is one of the important transporters of nutrients from the
environment and land masses to the oceans and regularly provides storage for
several compounds. The variations in suspended and dissolved discharge of the
river are more substantial than the changes in water discharge. (Suspended
and dissolved) organic carbons (SOC and DOC) are imperative segments in the
carbon cycle and fill in as essential food sources for amphibian sustenance
networks. In the present study, 26 samples of water were collected from
different locations over the 642 km stretch of the Ramganga River and its
adjoining tributaries to observe the spatial variation of DOC, dissolved
inorganic carbon (DIC), SOC and suspended inorganic carbon (SIC) in river
water. The DOC and DIC values of Ramganga River goes between 1.49 to 4.65 and
9.61 to 36.6 mg L−1 with an average convergence of 2.5 and
20 mg L−1, individually, while in case of tributaries, these values
extends between 0.09 to 4.52 and 4.61 to 42.36 mg L−1 with an average
convergence of 2.13 and 21.1 mg L−1, separately. The estimations of
SOC and SIC in the Ramganga River extend between 1.31 to 22.15 and 1.27 to
10.14 g kg−1 with an average convergence of 6.29 and
4.24 g kg−1, individually, though in tributaries, these values run
between 0.80 to 47.23 and 0.31 to 22.94 g kg−1 with an average
convergence of 9.25 and 5.14 g kg−1, separately. The results also show
the higher values of DOC as compared with SOC and these values shows an
increasing pattern with a decrease in elevation.
Spatiotemporal variability and assessment of drought in the Wei River basin of China
Authors: Cai Siyang , Zuo Depeng , Xu Zongxue , Han Xianming , Gao Xiaoxi
Published: June 2018

Abstract. The temporal and spatial variations of drought in the Wei River basin (WRB)
were investigated by calculating the meteorological drought Index
(Standardized Precipitation Index, SPI) and the agricultural drought index
(Vegetation Health Index, VHI). Monthly precipitation and air temperature
were from 22 meteorological stations over the region from 1960 to 2015.
Monthly Normalized Difference Vegetation Index (NDVI) and 8-days Land Surface
Temperature (LST) were provided from the National Aeronautics and Space
Administration (NASA) for the period 2000–2015 were also adopted. The
results showed that the drought initially increased and then decreased,
reaching at the maximum value in 1990s. The spatial pattern of meteorological
drought showed that the drought in northern WRB was heavier than that in
southern WRB before 1990s, after that, the situation had the opposite. By
comparing the agricultural drought index (VHI) with crop yield, it was proved
that VHI was applicable in the WRB and could well reflect the fluctuation of
agricultural drought. The WRB suffered from serious agricultural drought in
2000, 2001, 2007 and 2008. Through analysis of the historical precipitation
and temperature data, it was found that precipitation had a greater
contribution to creating agricultural drought conditions than temperature in
the Wei River basin.
Separation of soil respiration: a site-specific comparison of partition methods
Authors: Comeau Louis-Pierre , Lai Derrick Y. F. , Cui Jane Jinglan , Farmer Jenny
Published: June 2018

Abstract. Without accurate data on soil heterotrophic respiration (Rh), assessments of
soil carbon (C) sequestration rate and C balance are challenging to produce.
Accordingly, it is essential to determine the contribution of the different
sources of the total soil CO2 efflux (Rs) in different ecosystems,
but to date, there are still many uncertainties and unknowns regarding the
soil respiration partitioning procedures currently available. This study
compared the suitability and relative accuracy of five different Rs
partitioning methods in a subtropical forest: (1) regression between root
biomass and CO2 efflux, (2) lab incubations with minimally
disturbed soil microcosm cores, (3) root exclusion bags with hand-sorted
roots, (4) root exclusion bags with intact soil blocks and (5) soil
δ13C–CO2 natural abundance. The relationship
between Rh and soil moisture and temperature was also investigated. A
qualitative evaluation table of the partition methods with five performance
parameters was produced. The Rs was measured weekly from 3 February to
19 April 2017 and found to average
6.1 ± 0.3 MgCha-1yr-1. During this period, the Rh
measured with the in situ mesh bags with intact soil blocks and hand-sorted
roots was estimated to contribute 49 ± 7 and 79 ± 3 % of
Rs,
respectively. The Rh percentages estimated with the root biomass regression,
microcosm incubation and δ13C–CO2 natural abundance
were 54 ± 41, 8–17 and 61 ± 39 %, respectively. Overall,
no systematically superior or inferior Rs partition method was found. The
paper discusses the strengths and weaknesses of each technique with the
conclusion that combining two or more methods optimizes Rh assessment
reliability.
Snow depth on Arctic sea ice from historical in situ data
Authors: Shalina Elena V. , Sandven Stein
Published: June 2018

Abstract. The snow data from the Soviet airborne expeditions Sever in the
Arctic collected over several decades in March, April and May have been
analyzed in this study. The Sever data included more measurements and covered
a much wider area, particularly in the Eurasian marginal seas (Kara Sea,
Laptev Sea, East Siberian Sea and Chukchi Sea), compared to the Soviet North
Pole drifting stations. The latter collected data mainly in the central part
of the Arctic Basin. The following snow parameters have been analyzed:
average snow depth on the level ice (undisturbed snow) height and area of
sastrugi, depth of snow dunes attached to ice ridges and depth of snow on
hummocks. In the 1970s–1980s, in the central Arctic, the average depth of
undisturbed snow was 21.2 cm, the depth of sastrugi (that occupied about
30 % of the ice surface) was 36.2 cm and the average depth of snow near
hummocks and ridges was about 65 cm. For the marginal seas, the average depth
of undisturbed snow on the level ice varied from 9.8 cm in the Laptev Sea to
15.3 cm in the East Siberian Sea, which had a larger fraction of multiyear
ice. In the marginal seas the spatial variability of snow depth was
characterized by standard deviation varying between 66 and 100 %. The
average height of sastrugi varied from 23 cm to about 32 cm with standard
deviation between 50 and 56 %. The average area covered by sastrugi in
the marginal seas was estimated to be 36.5 % of the total ice area where
sastrugi were observed. The main result of the study is a new snow depth
climatology for the late winter using data from both the Sever expeditions
and the North Pole drifting stations. The snow load on the ice observed by
Sever expeditions has been described as a combination of the depth of
undisturbed snow on the level ice and snow depth of sastrugi weighted in
proportion to the sastrugi area. The height of snow accumulated near the ice
ridges was not included in the calculations because there are no estimates of
the area covered by those features from the Sever expeditions. The effect of
not including that data can lead to some underestimation of the average snow
depth. The new climatology refines the description of snow depth in the
central Arctic compared to the results by Warren et al. (1999) and provides
additional detailed data in the marginal seas. The snow depth climatology is
based on 94 % Sever data and 6 % North Pole data. The new climatology
shows lower snow depth in the central Arctic comparing to Warren climatology
and more detailed data in the Eurasian seas.
Comparison of Planetary Bearing Load-Sharing Characteristics in Wind Turbine Gearboxes
Authors: Keller Jonathan , Guo Yi , Zhang Zhiwei , Lucas Doug
Published: June 2018

Abstract. In this paper, the planetary load-sharing behaviour and fatigue life of different wind turbine gearboxes when subjected to rotor moments are examined. Two planetary bearing designs are compared – one design using cylindrical roller bearings with clearance and the other design using preloaded tapered roller bearings to support both the carrier and planet gears. Each design was developed and integrated into a 750-kilowatt gearbox. In field-representative dynamometer tests, the loads on each planet bearing row were measured and compared to finite element models. A significant improvement in planetary bearing load sharing was demonstrated in the gearbox with preloaded tapered roller bearings with maximum loads 20 % lower than the gearbox with cylindrical roller bearings. Bearing life was calculated with a representative duty cycle measured from field tests. The predicted fatigue life of the eight-combined planet and carrier bearings for the gearbox with preloaded tapered roller bearings is 3.5 times greater than for the gearbox with cylindrical roller bearings. The influence of other factors such as carrier and planet bearing clearance, gravity, and tangential pin position error is also investigated. The combined effect of gravity and carrier bearing clearance was primarily responsible for unequal load sharing. Reducing carrier bearing clearance significantly improved load sharing, while reducing planet clearance did not. Normal tangential pin position error did not impact load sharing due to the floating sun design of this three-planet gearbox.

O presente trabalho visa discutir o conceito de qualidade da educação a partir da adoção das avaliações em larga escala no Brasil, mais precisamente com a implementação do Índice de Desenvolvimento da Educação Básica (Ideb). Metodologicamente, utilizou-se de pesquisa bibliográfica, documental e de estudo de campo efetivado com a aplicação de questionários com questões abertas a professores do 5º ano do ensino fundamental. Este trabalho analisa a concepção gerencialista em contraposição à qualidade socialmente referenciada; amplia a discussão com a análise da presença do Ideb nos planos decenais de educação de âmbito nacional, estadual de Goiás e municipal de São Luís de Montes Belos-GO; e, por fim, apresenta e discute a percepção de professores de uma rede municipal de ensino a respeito do índice, analisando as implicações que o indicador tem trazido para o trabalho docente. O estudo dos planos estadual e municipal aponta para a reprodução do texto do PNE nos planos subnacionais enquanto que as falas dos docentes expressam as angústias que o Ideb tem acarretado ao trabalho pedagógico, pressionados pelo ranqueamento e necessidade de treinar continuamente os alunos para desempenho positivo no índice, num processo de responsabilização e culpabilização docente.
Multi-criteria decision-making model in the strategic planning of table egg production in the Republic of Croatia
Authors: Crnčan Ana , Škrtić Zoran , Kristić Jelena , Kralik Igor , Kranjac David , Hadelan Lari
Published: June 2018

Until 2012, egg production in Croatia was mostly in cages, which was not in accordance with the European Union standards on the welfare of laying hens. Therefore, producers of table eggs could not continue their current practice and had to use those systems permitted in the EU member countries, such as organic, free-range, indoor or enriched cages. The aim of this study was to analyse and evaluate various systems of table-egg production using a method of multi-criteria analysis called the Analytic Hierarchy Process (AHP). Thus, the aim was to determine scientifically which production system was the favoured option for the Croatian poultry sector. According to the results, production of eggs using an indoor system for housing hens was the best option (priority 0.317). This was followed by a free-range system (priority 0.242). The third-ranked alternative egg production system was in cages (priority 0.237), while the fourth and the least acceptable alternative refers to egg production according to organic principles (priority 0.202). Based on the results of the multi-criteria analysis and respecting the worldwide trends that reflect changes in consumers’ habits and their concerns for food safety and quality, as well as their preference for local markets and local products, it is recommended that eggs be produced in an indoor system of keeping laying hens. In this sense, egg production on small farms provides the possibility of self-employment and creation of additional income to contribute towards overall economic and social development of rural areas.

In this article, we presented two cases with catheter-relatedcomplications that occurred during intraperitoneal chemotherapy(IPC) following comprehensive cytoreductive surgery for ovariancarcinoma. One of the patients had bowel perforation which wasmanaged by removing the port and creating a colostomy. Theother had catheter blockage that was managed by releasing thecatheter from the fibrous adhesion. Both patients completed allcycles of chemotherapy without delay. IPC following optimalcytoreductive surgery in serous ovarian carcinoma holds promiseto improve survival. Catheter-related complications are one of themajor barriers that health care centers experience with the use ofcatheters in clinical practice. Yet, they can be managed withouthaving any delays in chemotherapy treatments.

In hospitals, transformational leadership proved to influence employee’s motivation and satisfaction (Spinelli, 2006, p.20) thus the hospital’s services. To our knowledge, there is no study conducted on the administrative employees in the healthcare sector in Lebanon that constitute our sample. There is only one study conducted on nurses by El-Jardali et al., (2008) in 69 hospitals in this country. Given this situation, we how can describe the relationship between transformational leadership and employee’s job satisfaction in hospitals? Data processing of a questionnaire administered to 455 employees of 28 over 125 hospitals in Lebanon shows that there is no significant relationship between the employee’s job satisfaction and these two transformational leadership components: leader’s idealized influence and intellectual stimulation. While we found a correlation between employee’s job satisfaction and two other components: inspirational motivation (Training; projects monitoring) and individualized consideration (Active listening to employee’s work issues).
Household Food Insecurity and Hunger in Selected Ethiopian Agricultural Communities: Examination of Supply and Demand Factors

Food insecurity and hunger are major challenges in many Ethiopian communities with repercussions on health and nutrition outcomes in vulnerable household members. The level and contextual risk factors of household food insecurity and hunger were assessed in households (n=630) from three rural communities of Ethiopia (Halaba or Zeway) using the Household Food Insecurity Access Scale and Household Hunger Scale. Multiple classification analysis was employed to explore the effects of key demand (e.g. household size, livestock) and supply (e.g. land size, frequency of production) factors and community (geographic location) as well as institutional (participation in food security programs) factors on food insecurity and hunger. Household food insecurity was unacceptably high in both districts (95% in Halaba & 67% in Zeway). Household hunger was 38% in Halaba and 18% in Zeway. Both food insecurity and hunger were significantly greater in Halaba (p<0.001), indicating an effect of geographic location. Both supply and demand factors were significant in determining household food insecurity and hunger (p<0.01); however, supply factors such as women’s access to land, land size and wealth had greater influence than the demand factors. Levels of food insecurity and hunger in both communities were very high and of serious concern. We recommend increasing the food supply, and its subsequent accessibility, for households through enhancing women’s access to land, improving income through savings and wealth accumulation, introducing more inclusive programs for women’s participation and reducing household work-burden by significantly enhancing productivity of cultivable land.
Pulses as Culturally Important Foods among University Students in Canada
Authors: Masuda Kristie
Published: June 2018

Pulses such as beans and lentils are culturally important foods in different countries/regions due to their traditional role in dishes, which may be a result of a combination of their nutritive qualities, low cost, and ease of storage. Despite the cultural, health, and monetary benefits associated with eating pulses, pulse consumption in Canada is low. The present study attempted to address whether cultural factors influence pulse consumption among university students in Canada. Results showed that 59% of respondents’ cultural identities do not impact their food choices, and just 29% indicated that pulses are part of their traditional diet.
Hannah Arendt and Edward Said
Authors: Burdon Peter ,   DePaul University
Published: June 2018

In this essay, I focus on the extent to which the condition of exile influenced the way Hannah Arendt and Edward Said engaged with the Israeli-Palestinian conflict and concepts of Binationalism. Part one is largely biographical and narrates the conditions under which both parties went into exile and they ways exile influenced their intellectual development and identity. Part two analyses Arendt’s early Jewish writings and the ways she sought to affirm notions of equality and Binationalism as a method for protecting stateless refugees. Following this, I consider Said’s concern for the memory and experience of victims and his argument that the shared histories of dispossession endured by Jews and Palestinians might form the basis for an alliance. While Binationalism has largely been erased from political discourse today, I conclude by suggesting that Said’s intervention offers useful tools through which Arendt’s proposals might be rethought or reimagined today.
Four new species of Xiphocentron Brauer, 1870 (Trichoptera: Xiphocentronidae) from the Atlantic Forest, southeastern Brazil

Published: June 2018

Four new species of Xiphocentron (Antillotrichia) Brauer, 1870 from the Atlantic forest are diagnosed, described and illustrated. All of them have a small mesal sclerite and a set of spines, differing in size, density and position, on the inner face of the inferior appendage. Moreover, tergum IX varies mostly in the shape of the posterior margin. Four species are described as new for science. Xiphocentron (Antillotrichia) copacabana sp. nov. is distinguished mainly by the projected basoventral margin of the inferior appendage, the spines are clustered in two regions and the quadrate posterior region of tergum IX. Xiphocentron (Antillotrichia) maracanan sp. nov is differentiated by the inferior appendage, with a strongly angled apical region of 90º. Xiphocentron (Antillotrichia) redentor sp. nov. differs by the inferior appendage, with a linear row of thick spines, and the tergum IX, with a posterior margin forming smoothly rounded lobes. Xiphocentron (Antillotrichia) tijuca sp. nov. is diagnosed by the subbasal region of the preanal appendage, which is markedly projected medially, and by the inferior appendage, which is thin subapically, enlarged apically and strongly bent dorsad.
Collections as data: Implications for enclosure
Authors: Padilla Thomas G.
Published: June 2018

In recent years a growing amount of interest has been dedicated to collections as data. A collections as data paradigm seeks to foster an expanded set of research, pedagogical, and artistic potential predicated on the computational use of cultural heritage collections. Collections as data raises the question of what it might mean to treat digitized and born digital collections as data rather than simple surrogates of physical objects or static representations of digital experience.
A place to study, a place to pray: Supporting student spiritual needs in academic libraries
Authors: Mross Emily , Riehman-Murphy Christina
Published: June 2018

Have you stumbled across a student using a tucked-away space in your library to pray? Maybe library staff have seen students using a study carrel, a stairway, or even the stacks. Perhaps students requested a space within the library to use for prayer or meditation, and now you provide a permanent space.At the Penn State-Harrisburg and Abington Libraries, we’ve witnessed students practicing their spirituality with whatever space is available or convenient. Through conversations with librarians at other Penn State campuses and at libraries across the United States, we discovered that our experiences were more common than we anticipated, regardless of the religious or secular status of the school. A number of academic libraries have transformed library spaces into areas for various spiritual practices to create a welcoming environment for all students, embarking into new user-centered territory.

La evolución del e-learning: del aula virtual a la red
Authors: Gros Salvat Begoña
Published: June 2018

El objetivo fundamental de este artículo es analizar la evolución y los retos del e-learning haciendo especial énfasis en la necesidad de pasar de un espacio cerrado –el aula virtual- a incorporar herramientas adaptativas que garanticen un uso mucho más personalizado. En el artículo se describe la evolución del e-learning desde el punto de vista pedagógico y tecnológico y se muestra como los espacios formativos se han diversificado más allá del aula virtual. El e-learning está incorporando diseños pedagógicos más abiertos en que diferentes personas pueden compartir contenidos, actividades y experiencias en situaciones formales e informales. Numerosas investigaciones muestran como en los entornos de aprendizaje en línea tienden a fracasan con los estudiantes con menos capacidad de autorregulación. Por el contrario, los estudiantes más exitosos muestran una mayor eficacia y eficiencia en los procesos de autorregulación. Las investigaciones sobre el papel de los estudiantes en los entornos virtuales de aprendizaje destacan la importancia de los procesos de autorregulación en el éxito de los resultados. Las tecnologías emergentes tales como el uso de sistemas adaptativos, los agentes inteligentes y el uso de las analíticas de aprendizaje pueden facilitar los procesos de adaptación y autorregulación ya que permiten ejercer una doble función: proporcionar información en tiempo real a los aprendices y facilitar estrategias de andamiaje durante el proceso de aprendizaje.
Uso de los registros de actividad para mejorar la colaboración en línea
Authors: Coll Salvador César , Engel Rocamora Anna , Niño Carrasco Shamaly
Published: June 2018

Se presenta una revisión de trabajos que centran su interés en la explotación de los datos que registran las plataformas de eLearning sobre la actividad de los participantes. Son propuestas que, mediante el análisis de estos datos, generan información que es ofrecida a los estudiantes, en tiempo real, para ayudarles a colaborar y aprender conjuntamente en la plataforma. En esta línea de investigación convergen trabajos de diferentes ámbitos de estudio como las analíticas del aprendizaje, la minería de datos, las herramientas de conciencia de grupo o las herramientas de análisis de la interacción. La revisión adopta una doble perspectiva: i) identificar y analizar los indicadores extraídos de los registros de actividad, su procesamiento, la información generada y las formas de comunicarla; y ii) explorar el modelo y los instrumentos utilizados para valorar el impacto que la información proporcionada tiene sobre los procesos colaborativos en línea y/o los resultados de aprendizaje. Las conclusiones subrayan que, en general, no se explicitan los modelos de aprendizaje colaborativo que fundamentan la selección de los indicadores ni la información comunicada a los estudiantes. También se detectan sesgos importantes como consecuencia de no tener en cuenta la naturaleza multidimensional de los procesos de aprendizaje colaborativo. Además, son pocos los trabajos que analizan las relaciones entre los usos que los estudiantes hacen de la información que reciben y la calidad de los procesos y los resultados del aprendizaje colaborativo, y cuando lo hacen no profundizan en los cambios que la información provoca en las dinámicas grupales.
Las diferentes concepciones de la universidad digital en Iberoamérica
Authors: Salinas Ibáñez Jesús , Marin Victoria Irene
Published: June 2018

En los últimos tiempos, se ha oído en muchas ocasiones hablar de la universidad digital en diversos contextos. Sin embargo, no hay una definición clara del concepto que ayude a concretar más su implementación. Por ello, este estudio se ha centrado en analizar las diferentes concepciones existentes de la universidad digital en Iberoamérica, mediante un análisis del campo semántico a través de análisis de redes y una revisión sistemática de literatura para identificar qué entienden las diferentes universidades iberoamericanas por ser una universidad digital. Se utilizaron palabras clave para la búsqueda partiendo de los tesauros e incluyendo la de “universidad digital” a través de diversos catálogos y bases de datos, y se localizaron documentos de diferentes tipos entre 2007 y 2017. La revisión de la literatura, a partir de los resúmenes de los trabajos, contempló la creación de categorías con diversos temas que representan cómo entiende Iberoamérica la universidad digital y con qué restricciones se topa. La discusión incorpora la integración de dichas categorías y temas a los modelos de universidad digital identificados previamente. A modo de conclusión, se presenta una síntesis sobre el concepto de universidad digital y apuntamos algunas notas hacia la realización de dicha concepción.
