Surface water storage is a key component of the terrestrial hydrological and biogeochemical cycles that also plays a major role in water resources management. In this study, surface water storage (SWS) variations are estimated at monthly time-scale over 15 years (1993–2007) using a hypsographic approach based on the combination of topographic information from Advance Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Hydrological Modeling and Analysis Platform (HyMAP)-based Global Digital Elevation Models (GDEM) and the Global Inundation Extent Multi-Satellite (GIEMS) product in the Ganges-Brahmaputra basin. The monthly variations of the surface water storage are in good accordance with precipitation from Global Precipitation Climatology Project (GPCP), river discharges at the outlet of the Ganges and the Brahmaputra, and terrestrial water storage (TWS) from the Gravity Recovery And Climate Experiment (GRACE), with correlations higher than 0.85. Surface water storage presents a strong seasonal signal (~496 km3 estimated by GIEMS/ASTER and ~378 km3 by GIEMS/HyMAPs), representing ~51% and ~41% respectively of the total water storage signal and it exhibits a large inter-annual variability with strong negative anomalies during the drought-like conditions of 1994 or strong positive anomalies such as in 1998. This new dataset of SWS is a new, highly valuable source of information for hydrological and climate modeling studies of the Ganges-Brahmaputra river basin.
Mapping Acute Coronary Syndrome Registries to SNOMED CT
Authors: Karlsson Daniel , Koch Sabine , Sulaiman Ismat Mohd
Published: March 2017

Background: Malaysia and Sweden have mapped their acute coronary syndrome registries using SNOMED CT. Since similar-purposed patient registries can be expected to collect similar data, these data should be mapped to the same SNOMED CT codes despite the different languages used. Previous studies have however shown variations in mapping between different mappers but the reasons behind these variations and the influence of different mapping approaches are still unknown.

Objectives: To analyze similar-purposed registries and their registry-to-SNOMED CT maps, using two national acute coronary syndrome registries as examples, to understand the reasons for mapping similarities and differences as well as their implications.

Methods: The Malaysian National Cardiovascular Disease - Acute Coronary Syndrome (NCVD- ACS) registry was compared to the Swedish Register of Information and Knowledge about Swedish Heart Intensive Care Admissions (RIKS- HIA). The structures of NCVD-ACS and RIKS-HIA registry forms and their distributions of headings, variables and values were studied. Data items with equivalent meaning (EDIs) were paired and their mappings were categorized into match, mismatch, and non-comparable mappings. Reasons for match, mismatch and non-comparability of each paired EDI were seen as factors that contributed to the similarities and differences between the maps.

Results: The registries and their respective maps share a similar distribution pattern regarding the number of headings, variables and values. The registries shared 101 EDIs, whereof 42% (42) were mapped to SNOMED CT. 45% (19) of those SNOMED CT coded EDIs had matching codes. The matching EDIs occurred only in pre-coordi- nated SNOMED CT expressions. Mismatches occurred due to challenges arising from the mappers themselves, limitations in SNOMED CT, and complexity of the registries. Non-comparable mappings appeared due to the use of other coding systems, unmapped data items, as well as requests for new SNOMED CT concepts.

Conclusions: To ensure reproducible and reusable maps, the following three actions are recommended: (i) develop a specific mapping guideline for patient registries; (ii) openly share maps; and (iii) establish collaboration between clinical research societies and the SNOMED CT community.

Published: March 2017

Many technological implementations in the field of nanotechnology have involved carbon nanomaterials, including fullerenes such as the buckminsterfullerene, C60. The unprecedented properties of such organic nanomaterials (in particular their large surface area) gained extensive attention for their potential use as organic pollutant sorbents. Sorption interactions can be very hazardous and useful at the same time. This work investigates the influence of halogenation by bromine and/or chlorine in dibenzo-p-dioxins on their sorption ability on the C60 fullerene surface. Halogenated dibenzo-p-dioxins (PXDDs, where X = Br or Cl) are ever-present in the environment and accidently produced in many technological processes in only approximately known quantities. If all combinatorial Br and/or Cl dioxin substitution possibilities are present in the environment, the experimental characterization and investigation of sorbent effectiveness is more than difficult. In this work, we have developed a quantitative structure–property relationship (QSPR) model (R2 = 0.998), predicting the adsorption energy [kcal/mol] for 1,701 PXDDs adsorbed on C60 (PXDD@C60). Based on the QSPR model reported herein, we concluded that the lowest energy PXDD@C60 complexes are those that the World Health Organization (WHO) considers to be less dangerous with respect to the aryl hydrocarbon receptor (AhR) toxicity mechanism. Therefore, the effectiveness of fullerenes as sorbent agents may be underestimated as sorption could be less effective for toxic congeners than previously believed.

Published: March 2017

Objective: To evaluate thermal and cardiorespiratory adaptation during hot tub bath and shower in healthy newborns in the first hours of life. Study design: This is a randomized blind controlled trial, registered in ReBEC (No. RBR-4z26f3) with 184 newborns divided into hot tub group (n=84) and shower (n=100). Newborns from intervention group were immersed in a hot tub with warm water up to the neck, without exposure to air flow, and control group received traditional shower. Heart rate, respiratory rate and temperature were measured before and immediately after bath by an investigator blinded to the type of bath.

Results: Groups were similar in gender, gestational age, birth weight, Apgar score at 5th minute and hours of life, p => 0.05. To analyze thermal and cardiorespiratory adjustments, difference between post-bath variables and pre-bath was calculated. In this analysis, it was found statistically significant difference between two types of bath regarding heart rate, respiratory rate and temperature. Hot tub bath decreases heart and respiratory rates and increases temperature, whereas shower provides the opposite effect (0.0001).

Conclusion: This study demonstrates that hot tub baths and shower, in healthy newborns, promote thermal and cardiorespiratory adaptations, reflecting thermal, cardiac and respiratory positive reactions after hot tub bath.

Introduction: The Centre for Health Support Family - NASF has a innovative character with potential to concretize change in the organization of services and in care practices, supporting and expanding the solvability of the actions of the teams of the Family Health Strategy - FHS. To this end, it must operationalize technologies, arrangements and care management devices.

Objective: To describe the care management technologies, particularly in the professional dimension, operated by the teams of the Support Centre for Family Health, in its dialogue with the Health Strategy.

Methods: case study with a qualitative approach, with the 12 professionals from a NASF team of Maracanaú, Ceará, Brazil. Focal group was performed. The empirical material was analysed based on the content analysis.

Results: there is evidence of a proposal for production of integral care based on the use of technologies as host, bond, autonomy and accountability. The user approach is based on the principles of the extended clinic. However, there are difficulties related to the regulation of access, the construction of bonds, the construction of therapeutic projects and intersectional articulation.

Final thoughts: it appears necessary to overcome the challenges, strengthen mechanisms for coordination and for negotiation of labour, as well as rethinking the NASF linking logic to a seemingly high number of FHS teams complicates the organization of work processes, building of agendas, weakens the bonds with the users and even the solvency.

Published: March 2017

Diabetic neuropathy refers to a group of symptoms associated with the nerve’s damaged ability to perform its functions correctly. Symptoms may vary from paresis to pains that mainly affect sensitive or motor long nerves of feet and hands. Hence, experiments and analysis carried out with rodents, especially rats, allow several clinical interfaces to be known. Therefore, the aim of this study was to analyze the factors associated with diabetic neuropathy in rats. This is a systematic review with metanalysis. Data collection followed some priorelection criteria. The sources of information for the researched data are the databases MEDLINE/PubMed and Scopus. The research was conducted using the keywords found in descriptors/MeSH: rats, diabetic neuropathies, and risk factors with the Boolean operator “AND”.

The BioEstat 5.3 was used for statistical analysis, and the Odds Ratio was calculated with a 95% confidence interval (CI). Eighty-three references were found, of which 17 followed the criteria and were then included in the present review. Some factors like nerve morphology, blood hypertension, oxidative stress, diabetes period, hypoglycemic effect, vascular complications, and insulin parameters represent the main risk factors for the development of diabetic neuropathy, as well as diabetes induction in rats by using drugs. Such factors are verysimilar to those from humans, thus requiring a deeper analysis of the theme in a considerable human sample.
An Enhanced Method for Scheduling Observations of Large Sky Error Regions for Finding Optical Counterparts to Transients

Published: March 2017

The discovery and subsequent study of optical counterparts to transient sources is crucial for their complete astrophysical understanding. Various gamma-ray burst (GRB) detectors, and more notably the ground-based gravitational wave detectors, typically have large uncertainties in the sky positions of detected sources. Searching these large sky regions spanning hundreds of square degrees is a formidable challenge for most ground-based optical telescopes, which can usually image less than tens of square degrees of the sky in a single night. We present algorithms for better scheduling of such follow-up observations in order to maximize the probability of imaging the optical counterpart, based on the all-sky probability distribution of the source position. We incorporate realistic observing constraints such as the diurnal cycle, telescope pointing limitations, available observing time, and the rising/setting of the target at the observatory’s location. We use simulations to demonstrate that our proposed algorithms outperform the default greedy observing schedule used by many observatories. Our algorithms are applicable for follow-up of other transient sources with large positional uncertainties, such as Fermi-detected GRBs, and can easily be adapted for scheduling radio or space-based X-ray follow-up.
A Lower Bound on Adiabatic Heating of Compressed Turbulence for Simulation and Model Validation
Authors: Davidovits Seth , Fisch Nathaniel J.
Published: March 2017

The energy in turbulent flow can be amplified by compression, when the compression occurs on a timescale shorter than the turbulent dissipation time. This mechanism may play a part in sustaining turbulence in various astrophysical systems, including molecular clouds. The amount of turbulent amplification depends on the net effect of the compressive forcing and turbulent dissipation. By giving an argument for a bound on this dissipation, we give a lower bound for the scaling of the turbulent velocity with the compression ratio in compressed turbulence. That is, turbulence undergoing compression will be enhanced at least as much as the bound given here, subject to a set of caveats that will be outlined. Used as a validation check, this lower bound suggests that some models of compressing astrophysical turbulence are too dissipative. The technique used highlights the relationship between compressed turbulence and decaying turbulence.
Star Cluster Formation from Turbulent Clumps. I. The Fast Formation Limit
Authors: Farias Juan P. , Tan Jonathan C. , Chatterjee Sourav
Published: March 2017

We investigate the formation and early evolution of star clusters, assuming that they form from a turbulent starless clump of a given mass bounded inside a parent self-gravitating molecular cloud characterized by a particular mass surface density. As a first step, we assume instantaneous star cluster formation and gas expulsion. We draw our initial conditions from observed properties of starless clumps. We follow the early evolution of the clusters up to 20 Myr, investigating the effects of different star formation efficiencies, primordial binary fractions and eccentricities, and primordial mass segregation levels. We investigate clumps with initial masses of

embedded in ambient cloud environments with mass surface densities

and

. We show that these models of fast star cluster formation result, in the fiducial case, in clusters that expand rapidly, even considering only the bound members. Clusters formed from higher

environments tend to expand more quickly and thus are soon larger than clusters born from lower

conditions. To form a young cluster of a given age, stellar mass, and mass surface density, these models need to assume a parent molecular clump that is many times denser, which is unrealistic compared to observed systems. We also show that, in these models, the initial binary properties are only slightly modified by interactions, meaning that the binary properties, e.g., at 20 Myr, are very similar to those at birth. With this study, we set up the foundation for future work, where we will investigate more realistic models of star formation compared to this instantaneous, baseline case.
Terrestrial Planet Formation: Constraining the Formation of Mercury
Authors: Lykawka Patryk Sofia , Ito 伊 Takashi 藤孝士
Published: March 2017

How the four terrestrial planets of the solar system formed is one of the most fundamental questions in the planetary sciences. Particularly, the formation of Mercury remains poorly understood. We investigated terrestrial planet formation by performing 110 high-resolution N-body simulation runs using more than 100 embryos and 6000 disk planetesimals representing a primordial protoplanetary disk. To investigate the formation of Mercury, these simulations considered an inner region of the disk at 0.2–0.5 au (the Mercury region) and disks with and without mass enhancements beyond the ice line location, a
IL, in the disk, where a
IL = 1.5, 2.25, and 3.0 au were tested. Although Venus and Earth analogs (considering both orbits and masses) successfully formed in the majority of the runs, Mercury analogs were obtained in only nine runs. Mars analogs were also similarly scarce. Our Mercury analogs concentrated at orbits with a ∼ 0.27–0.34 au, relatively small eccentricities/inclinations, and median mass m ∼ 0.2

. In addition, we found that our Mercury analogs acquired most of their final masses from embryos/planetesimals initially located between 0.2 and ∼1–1.5 au within 10 Myr, while the remaining mass came from a wider region up to ∼3 au at later times. Although the ice line was negligible in the formation of planets located in the Mercury region, it enriched all terrestrial planets with water. Indeed, Mercury analogs showed a wide range of water mass fractions at the end of terrestrial planet formation.
Testing the Accuracy of Data-driven MHD Simulations of Active Region Evolution
Authors: Leake James E. , Linton Mark G. , Schuck Peter W.
Published: March 2017

Models for the evolution of the solar coronal magnetic field are vital for understanding solar activity, yet the best measurements of the magnetic field lie at the photosphere, necessitating the development of coronal models which are “data-driven” at the photosphere. We present an investigation to determine the feasibility and accuracy of such methods. Our validation framework uses a simulation of active region (AR) formation, modeling the emergence of magnetic flux from the convection zone to the corona, as a ground-truth data set, to supply both the photospheric information and to perform the validation of the data-driven method. We focus our investigation on how the accuracy of the data-driven model depends on the temporal frequency of the driving data. The Helioseismic and Magnetic Imager on NASA’s Solar Dynamics Observatory produces full-disk vector magnetic field measurements at a 12-minute cadence. Using our framework we show that ARs that emerge over 25 hr can be modeled by the data-driving method with only ∼1% error in the free magnetic energy, assuming the photospheric information is specified every 12 minutes. However, for rapidly evolving features, under-sampling of the dynamics at this cadence leads to a strobe effect, generating large electric currents and incorrect coronal morphology and energies. We derive a sampling condition for the driving cadence based on the evolution of these small-scale features, and show that higher-cadence driving can lead to acceptable errors. Future work will investigate the source of errors associated with deriving plasma variables from the photospheric magnetograms as well as other sources of errors, such as reduced resolution, instrument bias, and noise.
Bar-induced Central Star Formation as Revealed by Integral Field Spectroscopy from CALIFA
Authors: Lin Lin , Li Cheng , He Yanqin , Xiao Ting , Wang Enci
Published: March 2017

We investigate the recent star formation history (SFH) in the inner region of 57 nearly face-on spiral galaxies selected from the Calar Alto Legacy Integral Field Area (CALIFA) survey. For each galaxy, we use the integral field spectroscopy from CALIFA to obtain two-dimensional maps and radial profiles of three parameters that are sensitive indicators of the recent SFH: the 4000 Å break (D

n
(4000)), and the equivalent width of Hδ absorption (

) and Hα emission (EW(Hα)). We have also performed photometric decomposition of bulge/bar/disk components based on SDSS optical image. We identify a class of 17 “turnover” galaxies for which the central region presents a significant drop in D

n
(4000), and most of them correspondingly show a central upturn in

and EW(Hα). This indicates that the central region of the turnover galaxies has experienced star formation in the past 1–2 Gyr, which makes the bulge younger and more star-forming than surrounding regions. We find that almost all (15/17) of the turnover galaxies are barred, while only half of the barred galaxies in our sample (15/32) are classified as a turnover galaxies. This finding provides strong evidence in support of the theoretical expectation that the bar may drive gas from the disk inward to trigger star formation in the galaxy center, an important channel for the growth/rejuvenation of pseudobulges in disk galaxies.
Effect of Alignment on Polarized Infrared Emission from Polycyclic Aromatic Hydrocarbons
Authors: Hoang Thiem
Published: March 2017

Polarized emission from polycyclic aromatic hydrocarbons (PAHs) potentially provides a new way to test the basic physics of the alignment of ultrasmall grains. In this paper, we present a new model of polarized PAH emission that takes into account the effect of PAH alignment with the magnetic field. We first generate a large sample of the grain angular momentum

by simulating the alignment of PAHs due to resonance paramagnetic relaxation that accounts for various interaction processes. We then calculate the polarization level of the PAH emission features for the different phases of the interstellar medium, including the cold neutral medium (CNM), reflection nebulae (RNe), and photodissociation regions. We find that a moderate degree of PAH alignment can significantly enhance the polarization degree of the PAH emission compared to the previous results obtained with randomly oriented angular momentum. In particular, we find that the smallest negatively charged PAHs in RNe can be excited to slightly suprathermal rotation due to enhanced ion collisional excitation, resulting in an increase of the polarization with the ionization fraction. Our results suggest that an RN is the most favorable environment in which to observe polarized PAH emission and to test the alignment physics of nanoparticles. Finally, we present an explicit relationship between the polarization level of PAH emission and the degree of external alignment for the CNM and RNe. The obtained relationship will be particularly useful for testing the alignment physics of PAHs in future observations.
Triggering the Formation of Direct Collapse Black Holes by Their Congeners

Published: March 2017

Direct collapse black holes (DCBHs) are excellent candidates for seeds of supermassive black holes observed at z ≳ 6. The formation of a DCBH requires a strong external radiation field to suppress H2 formation and cooling in a collapsing gas cloud. Such a strong field is not easily achieved by first stars or normal star-forming galaxies. Here we investigate a scenario in which a previously formed DCBH can provide the necessary radiation field for the formation of additional ones. Using a one-zone model and simulated DCBH Spectral Energy Distributions (SEDs) filtered through absorbing gas initially having column density N
H, we derive the critical field intensity,

, to suppress H2 formation and cooling. For the SED model with

cm−2, 8.0 × 1024 cm−2, and 5.0 × 1024 cm−2, we obtain

, 35, and 54, all much smaller than the critical field intensity for normal star-forming galaxies

X-ray photons from previously formed DCBHs build up a high-z X-ray background (XRB) that may boost the

only increases to ≈80, 170, and 390, even when

reaches the maximum value allowed by the present-day XRB level (0.22, 0.034, 0.006 M
⊙ yr−1 Mpc−3), which is still much smaller than the galactic value. Although considering the XRB from first galaxies may further increase

, we conclude that our investigation supports a scenario in which DCBHs may be more abundant than predicted by models only including galaxies as external radiation sources.

We do not find significant offsets between DM and galaxies, but the uncertainties are large with the current lensing data. Furthermore, in the east, the BCG is offset from other luminous cluster galaxies, which poses a puzzle for defining DM–galaxy offsets.
Multi-wavelength Spectral Analysis of Ellerman Bombs Observed by FISS and IRIS
Authors: Hong Jie , Ding M. D. , Cao Wenda
Published: March 2017

Ellerman bombs (EBs) are a kind of solar activity that is suggested to occur in the lower solar atmosphere. Recent observations using the Interface Region Imaging Spectrograph (IRIS) show connections between EBs and IRIS bombs (IBs), which imply that EBs might be heated to a much higher temperature (8 × 104 K) than previous results. Here we perform a spectral analysis of EBs simultaneously observed by the Fast Imaging Solar Spectrograph and IRIS. The observational results show clear evidence of heating in the lower atmosphere, indicated by the wing enhancement in Hα, Ca ii 8542 Å, and Mg ii triplet lines and also by brightenings in images of the 1700 Å and 2832 Å ultraviolet continuum channels. Additionally, the intensity of the Mg ii triplet line is correlated with that of Hα when an EB occurs, suggesting the possibility of using the triplet as an alternative way to identify EBs. However, we do not find any signal in IRIS hotter lines (C ii and Si iv). For further analysis, we employ a two-cloud model to fit the two chromospheric lines (Hα and Ca ii 8542 Å) simultaneously, and obtain a temperature enhancement of 2300 K for a strong EB. This temperature is among the highest of previous modeling results, albeit still insufficient to produce IB signatures at ultraviolet wavelengths.
Characterization of ESBL-producing Escherichia coli recovered from companion dogs in Tai'an, China
Authors: Li Song , Liu Junhe , Zhou Yufa , Miao Zengmin
Published: March 2017

Introduction: Animals are considered to be reservoirs of extended-spectrum beta-lactamase (ESBL)-producing bacteria, but few epidemiological data on ESBL-producing Escherichia coli urinary tract isolates in pet dogs are available in China. Methodology: This study was conducted to describe the prevalence and characterization of ESBL producers among E. coli urinary tract isolates from pet dogs in Tai'an, China. Results: A total of 118 E. coli were obtained from urinary samples of 80 companion dogs suffering from acute or chronic cystitis, of which three isolates from different dogs were ESBL producers. One isolate from dog A was of phylogroup A/ST410/CTX-M-15/TEM-1; one from dog B was of phylogroup B1/ST533/CTX-M-15/TEM-1; one from dog C was of phylogroup D/ST648/CTX-M-15. All ESBL producers were resistant to ampicillin, cephalexin, cefalotin, cefpodoxime, ceftiofur, enrofloxacin, marbofloxacin, and trimethoprim/sulfamethoxazole, but were susceptible to imipenem and amoxicillin/clavulanic acid. E. coli of ST533 carrying blaCTX-M-15 were first detected in pet dogs in China. Conclusions: Collectively, the findings could expand our knowledge about the prevalence and characterization of ESBL-producing E. coli urinary tract isolates in pet dogs in China.
Increasing RN Perceived Competency With Substance Use Disorder Patients
Authors: Russell Regina , Ojeda Maria M. , Ames Barbara
Published: March 2017

Background:

Although behavioral health and substance use disorder patients visit hospitals in significant numbers, nurses are often ill-prepared to care for them.

Method:

The purpose of this quasi-experimental preclass–postclass design was to determine the effects of an educational intervention on the perceived competency of 57 nurses who care for patients with behavioral and substance abuse disorders. The nurses who chose to participate were asked to respond to a demographic questionnaire and a survey designed to measure perceived competency. Survey data were analyzed to determine whether any differences (alpha = .05) existed between participants' attitudes and knowledge preclass and postclass.

Results:

Immediately following the educational intervention, a statistically significant increase was found in perceived competency related to self-confidence, attitudes, communication, and knowledge of resource availability among participating nurses.

Conclusion:

Nurses working in acute care hospitals, particularly those without addiction and psychiatric services, may benefit from continuing education on this important topic.

Les identités de genre dans le cinéma des premiers temps : problématiques d’une approche
Authors: Cherubini Jean-Marie
Published: March 2017

Si les Gender Studies constituent depuis maintenant plusieurs années un domaine de recherche reconnu et institutionnalisé, elles n’en restent pas moins soumises à de nombreux reproches dans les milieux académiques, notamment en ce qui concerne l’objectivité scientifique des démarches et des résultats proposés. Lorsqu’on examine les théories qui se penchent sur le cinéma des premiers temps, cet aspect se perçoit nettement. Mais en parallèle, surtout depuis une dizaine d’années, d’autres approches montrent que la dimension idéologique n’est pas nécessairement intrinsèque à ce champ d’étude. Inspirées des chercheurs-euses de Brighton, ainsi que de la théorie du dispositif, celles-ci cherchent à déterminer la place et la fonction du genre dans ce cinéma et proposent, de ce fait, une approche épistémologique de laquelle ressort ce constat : le genre, conçu comme catégorie analytique est un concept qui a sa place dans l’histoire du cinéma.

« Je pense que vous savez que je suis cinéaste... » Ainsi Eric Rohmer commence-t-il son cours du 29 octobre 1990 à l’université de Paris I. Il s’agit de sa vingt-deuxième rentrée universitaire, et l’on peut penser que l’enseignant, qui a de la bouteille, commence ses cours en appuyant sur cet effet rhétorique amusant depuis un certain temps, peut-être depuis l’automne 1969, sa première rentrée, qui suit de quelques mois la sortie en salles de Ma nuit chez Maud, qui s’avère un triomphe inattendu, attirant plus d’un million de spectateurs, faisant brusquement de ce théoricien et critique reconnu mais plutôt obscur, auteur de films confidentiels, un réalisateur à succès...

Music production in the 21st century shifted from a largely commodified industrial model to a radically decentralized one, technologically facilitated by new efficiencies in search of functionality, delivery, and peer-to-peer connectivity. In the older music economy, the media of music (its tangible forms—vinyl, cassette, compact disc, etc.) were fused with its contents (its sounding forms—songs, pieces, etc.), thereby facilitating their efficient circulation as physical commodities (grounded in licensing agreements, copyright protections, and so on). In the newer economy, medium and content are increasingly delinked; the former is effectively dematerialized (or, more accurately, micro-materialized as virtualized format), thereby posing new challenges to law and policy governing musical creation, distribution, and consumption. In the context of music’s new technological prostheses (digital recording studios, on-demand streaming services, algorithmic aggregators, and the like) the question of equitable sources of revenue for musical labor has re-surfaced as a central debate in our times. The article assesses the promise of disintermediation in relation to new formations of labor, characterized by increased entrepreneurial reliance on flexible and globalized networks of production and distribution.

With the rapid advancements in the internet technology, many retailers are embracing internet of things technology to enhance customer experience and improve efficiency. Specifically, many customer-facing IoT technologies such as augmented reality, smart shopping carts, smart displays, and RFID tags are expected to change the way customers experience retailing shopping. Drawing on the technology acceptance model, trust perspective, task-technology fit, and organizational reputation perspective, this study examines the customer adoption of IoT applications in retail setting. Responses collected from 289 actual retail shoppers were analyzed using structural equation modeling. Results reveal that perceived usefulness, perceived ease of use, task-technology fit, retailer reputation, and initial trust are significant predictors of customer attitude and intentions to use IoT in retail stores. The study findings have key implications for academicians and retailers in improving customer acceptance and in delivering superior customer experience.
The Internet of Things
Authors: Ochs Thomas , Riemann Ute Anna
Published: March 2017

Objects become embedded and gain the ability to communicate. The resulting information networks promise to create new business models, improve business processes, and reduce costs and risks. The massive numbers of connected things and the explosion of data generated by these things will change the way we do business forever. Connected devices are proliferating in a communicating and actuating network named “Internet of Things” (IoT) wherein sensors and actuators blend seamlessly with the environment around us, and the information is shared across platforms in order to develop a common operating picture (Gubi et al., 2013). The IoT digitizes the physical world and is a basis for new business models whose main objective is to integrate or connect things. This chapter outlines the key enabling technologies, drivers and business value as well as benefits and challenges.
Flipping Our Urban Charter ELA Classes
Authors: Shaffner Samantha , Hyland Anne M.
Published: March 2017

The Flipped Mastery Model (Bergmann & Sams, 2012) makes English language arts (ELA) content accessible to students, no matter the learning environment (individual vs. community). At our urban charter high school, students are often times faced with the academic challenges connected to living in high poverty homes. Having more than one dispenser of information has proven to be an effective solution to the educational barriers that occur as a result of a student having poor attendance that may eventually lead to academic failures. Skills students acquire from having consistent and transparent access to ELA content often leads to an increased amount of academic successes, directly through the practice and use of Google Applications for Education, and more specifically, Google Classroom. Supporting ELA content area learning through the features of Google Classroom allows students to become an important member of virtual learning communities that can be academically supportive and, likewise, can provide opportunities for students to master related College and Career Readiness Standards specific to ELA.
Using Web-Based Tools for Flipped ESL Learning in the Korean Language Education System
Authors: Lee YunJoon Jason
Published: March 2017

With the continued proliferation of digital technologies, students are absorbing more information than ever. As a result, the relationship between students and teachers in a traditional face-to-face classroom can be limiting. As the flipped classroom approach has emerged, the classroom culture has changed. The active environment, interactive approach, and content-specific flipped learning has great potential for the ESL-learning context, especially for Korean college students. Korean college students were accustomed to the face-to-face, top-down structure of learning, and flipped learning provided an opportunity for them to look at and experience learning differently. More specifically, the top-down relationship between teacher and student shifted into a more balanced and interactive learning culture. The positive aspects of flipped learning were beneficial for the Korean ESL college students. This chapter features a case study of a college English language conversation class in Korea and explores how to set up a flipped classroom through web-based tools in order to keep the students motivated and generate a participatory environment.
Flipping the Flip to Empower Students

One of the key criticisms leveled at the flipped method of instruction is that it is simply “business as usual” with teachers delivering didactic lectures, and the students relying on them for information. To address this issue, the authors each enacted a form of flipping in their respective classroom contexts in which students made digital videos for their peers to view for instructional gain. This process, which the authors dubbed SMILE (Student Made Inquiry-based Learning Experience), advocates for students to be the creators of content actively engaging their peers. Rather than teachers serving in a more traditional role, they serve as facilitators in this model. Results from action research across the varying classroom contexts indicated that students were highly engaged and achieved targeted learning goals through the SMILE process.

Published: March 2017

The aim of this paper is to examine the use of digital technologies in Science, Technology, Engineering, and Mathematics Education (STEM). We will discuss the effectiveness of the teaching-learning process in terms of the elements that could possibly promote learning with the use of Information and Communication Technologies (ICT) in STEM education. This will be done, first, by taking a learner-centred approach to an activity that students carried out using ICT to performing a task set by the teacher (cognitive engagement in the task, motivation, nature of knowledge built). The aim was to understand how ICT could be a cognitive aid for the student. Second, a teacher-centred perspective to the development of prescribed tasks (form, knowledge carried by the task) was used to identify how ICT can be adapted to aid student learning in STEM education.
