Modeling the Deformation Regime of Thwaites Glacier, West Antarctica, Using a Simple Flow Relation for Ice Anisotropy (ESTAR)

Ice deformation dominates the evolution of ice shelf flow and the slow‐moving regions in the interior of ice sheets. However, deformation may be poorly represented in large‐scale ice sheet models that use the Glen flow relation, due to its questionable applicability to the steady‐state flow of anisotropic ice that prevails in ice sheets, having been derived from secondary creep rates of isotropic ice. We assess the deformation regimes of Thwaites Glacier, West Antarctica, using the Glen and “Empirical Scalar Tertiary Anisotropy Regime”, (ESTAR) flow relations, the latter being derived from steady‐state deformation rates of anisotropic ice. For grounded ice, the character of the flow relation determines the contribution of deformation to overall flow, with ESTAR producing greater bed‐parallel shear deformation than the standard Glen flow relation. The ESTAR experiments show larger basal shear stress maxima than the standard Glen experiment because ESTAR treats the responses to simple shear stresses and compression stresses differently, reducing the role of lateral and longitudinal stresses in momentum balance. On the Thwaites Glacier Tongue, ESTAR provides the best match to observed speeds by accounting for the differing effects of stresses on ice flow. Our results highlight the importance of the numerical description of anisotropy, particularly: In regions of transition from deformation‐dominated to sliding‐dominated flow; in the approach to the grounding line, and across ice shelves. Given the importance of these locations in determining mass flux into the ocean, our results have implications for projections of sea level change from Antarctic ice loss.
Choroidal Structural Changes of Posterior Subtenon Triamcinolone Acetonide Injection in Eyes with Refractory Diabetic Macular Edema

Purpose To access the choroidal structural changes of posterior subtenon triamcinolone acetonide (PSTA) injection in eyes with refractory diabetic macular edema (DME). Methods Patients with refractory DME were enrolled and followed for 4 weeks after switching to PSTA injection. All patients underwent spectral-domain optical coherence tomography with enhanced depth imaging, and the choroidal images were binarized into the luminal area and total choroidal area. Subfoveal choroidal thickness (SFCT) and choroidal vascularity index (CVI) were evaluated before and after switching treatments. Results After switching to PSTA treatment, the final best-corrected visual acuity and central subfield thickness in eyes with refractory DME were significantly improved compared to the baseline values (P=0.002 and P < 0.001, respectively). Both the SFCT and CVI decreased during the follow-up period, and significant decreases were observed at 4-week follow-up (P < 0.001 and P=0.012, respectively). The linear regression analysis showed a significant correlation between the baseline SFCT and the final visual outcomes (P=0.047). Conclusions The alterations of SFCT and CVI in this study suggest that the choroidal vasculature is involved in the pathogenesis of refractory DME and could be affected by PSTA treatment. SFCT rather than CVI may be a prognostic biomarker for eyes with refractory DME.
Satellite Observations of the Impact of Individual Aircraft on Ice Crystal Number in Thin Cirrus Clouds

Contrails can persist in cloud‐free supersaturated air, increasing high‐cloud cover, and inside natural cirrus cloud, modifying the microphysical properties of them. The latter effect is almost unknown, partly because of the lack of height‐resolved measurements and the capability of measurements to penetrate inside the cloud. New retrievals of the ice crystal number concentration from combined satellite cloud radar and lidar measurements (CloudSat/CALIPSO; DARDAR‐Nice algorithm) now allow for satellite‐based assessment inside the clouds. We investigate this issue at intersections between the aircraft flight tracks and these retrieval profiles. Regions behind the aircraft inside the flight track were compared to the adjacent regions and to ahead of the aircraft, along the satellites' profiles, where DARDAR‐Nice identify geometrically thin cirrus clouds. This comparison revealed a statistically significant increase of 25% and 54% in the concentration of ice crystals with the minimum size of 5 μm around 300–540‐m beneath an aircraft's flight altitude.
What if? Using counterfactuals to evaluate the effects of structural labour market reforms: evidence from the Italian Jobs Act

ABSTRACT The article assesses the impact of the Jobs Act, the labour market reform passed in Italy under Matteo Renzi’s cabinet in 2014–2015. In doing so, the study has a twofold aim. First, it contributes to the scholarly debate on labour market flexibilization, offering fresh empirical evidence about the debated effects of deregulatory reforms on employment performance. Second, our empirical investigation relies on an innovative approach, the synthetic control method, which allows us to estimate what would have happened if the Jobs Act had not been introduced. After the downturns of the Great Recession, the major goal of this flagship initiative was to boost overall employment performance while reducing labour market segmentation and enhancing more stable job opportunities for labour market outsiders, especially among younger cohorts and women. Comparing real-world observations for a number of key employment indicators with their estimated synthetic counterfactuals, we find that the Jobs Act did not fulfil its expectations. In line with part of the most recent literature addressing the impact of deregulatory reforms on employment performance, our results show that over the past five years no significant effects were driven by the reform, which may even have led to an increase in labour market segmentation.
Experiencing Meaningful Work as a Lower Socioeconomic Status Worker: An Interpretative Phenomenological Analysis

Meta-analytic evidence suggests that experiencing one’s work as meaningful is associated with many psychological benefits. The experience of meaningful work in people with lower socioeconomic status (LSES), however, is underrepresented in the literature. This study examines how LSES individuals describe their experience of meaningful work (MW) in their unique contexts through an interpretative phenomenological analysis approach. Eight LSES workers in the Western United States from diverse backgrounds were interviewed. Data analysis resulted in five domains and 17 nested super-ordinate themes which captured participants’ definitions and experiences of MW, psychosocial and contextual conditions that support or hinder MW, and the impact of MW in their personal lives. LSES individuals navigated their own way to experience MW in their unique contexts despite socioeconomic barriers. Implications for future research and practice for LSES workers are discussed.
Research into the evaluation of PR activities in companies from Serbia

This paper presents the results of a research into the volume, type and quality of the evaluation of public relations activities in companies in Serbia. The survey was conducted via a web survey. The responses were collected from 50 PR service managers from 50 companies in Serbia. The results are presented through descriptive statistics and correlation analysis where some of the observed sizes of the connection were analyzed. The main conclusions can be summarized as follows: PR functions are often not assigned sufficient importance in companies in Serbia; the evaluation of PR activity is slightly neglected compared to other PR activities; intensive and continuous evaluation of the performances of PR activities increases the likelihood of the complete PR function of the company being successful; companies that are not so successful use evaluation less than successful companies; the evaluation of PR activities is mostly done through a method for measuring quantity; the main problems in the evaluation of PR activities are lack of time and money. The evaluation of PR activities in companies in Serbia can be improved through a greater understanding on the part of top managers, and also by hiring additional PR practitioners.
Investigating the impact of Saharan dust aerosols on analyses and forecasts of African easterly waves by constraining aerosol effects in radiance data assimilation

Abstract. This study incorporates aerosol effects into satellite radiance calculations within the Global Data Assimilation System (GDAS) to investigate its impact on the analyses and forecasts of African easterly waves (AEWs). Analysis fields from the aerosol-aware assimilation experiment were compared to an aerosol-blind control during August 2017. The results showed that the aerosol-aware assimilation warmed the Saharan boundary layer, accelerated the African easterly jet, and modified the time-averaged AEWs by enhancing the northern track and reducing the southern track. The changes to the tracks are qualitatively consistent with arguments of baroclinic and barotropic instability. During the time period, we also examined two AEWs that developed hurricanes Gert and Harvey over the Atlantic but were structurally different over Africa; the AEW for Gert consisted of a southern vortex, while the AEW for Harvey consisted of a northern and southern vortex. Analysis differences of the cases showed stronger vorticity changes for the AEW that developed Harvey, which we attribute to the aerosol-aware assimilation capturing the radiative effects of a large-scale Saharan dust plume interacting with the northern vortex of the wave. Subsequent forecasts for the AEW cases using the Global Forecast System (GFS, v14) showed that the aerosol-aware assimilation reduced errors in the downstream vorticity structure for the AEW that developed Harvey; neutral improvement was found for the AEW that developed Gert. Thus, aerosol-affected radiances in the assimilation system have the ability to account for dust radiative effects on the analyzed AEWs, which, in turn, can improve the forecasting of AEWs downstream.

Vitamin E Extraction from Magnesium Salts of Palm Fatty Acid Distillates

This research studied how the type of organic solvent and the number of extraction stages affect the vitamin E cumulative extraction yield and recovery rate from Mg-PFAD. First, PFAD was saponified to produce Mg-PFAD, then vitamin E was extracted from the Mg-PFAD using ethanol, isopropanol, or hexane, followed by evaporation to produce vitamin E concentrate. Three-stage hexane extraction with a solvent to Mg-PFAD mass ratio of 3 kg solvent/kg Mg-PFAD produced the highest vitamin E recovery rate. Organic solvent with a lower polarity gave a higher extraction yield and recovery rate of vitamin E from Mg-PFAD. In general, an increase of the number of extraction stages led to an increase of the vitamin E extraction yield and recovery rate from Mg-PFAD.
In-Service EFL teachers’ engagement in reflexive practice via video enhanced observation

ABSTRACT Building upon the interrelationship between learning and changing, this study investigates how cyclical engagement in reflexive practice influences the teachers’ professional development. We implemented our video-enhanced ‘Reflexive Practice Triplication Model’ which we developed in our specific context. We conducted the research with 8 secondary school teachers of English at a private K12 school in Ankara, Turkey. Drawing on multiple sources of data, we used a triangulation technique to reveal the qualitative and quantitative impact of reflexive practice. The findings showed that collaborative engagement in reflexive practice contributed substantially to EFL teachers’ professional development traceable in the changes in beliefs on reflexivity, attitudes towards collaboration, contextual and pedagogical knowledge. The study provides implications as to how reflexive practice can be used in local contexts where specific needs are to be considered.
Instrumental Support, Relational Attachment, and Subjective Career Success: The Moderating Role of Personal Support

Support at work has been linked to a wide range of positive individual and organizational outcomes. However, research to date has overlooked its influence on career-related outcomes. Drawing on attachment theory, we examined the relationship between instrumental support and two aspects of subjective career success—job satisfaction and career satisfaction—and the mediating and moderating roles of relational attachment and personal support, respectively. Results from survey data collected from employees working in Poland provide support for our hypothesized relationships. The findings contribute to a richer understanding of how and when employee subjective career success is influenced by social support and positive relationships in work life. Our findings have theoretical implications for social support, positive workplace relationships, and career success literatures.
The relationship between retailer app use, perceived shopping value and loyalty: the moderating role of deal proneness

Purpose This paper studies the effects of retailer app use on perceived shopping value and loyalty toward the retailer. It also investigates whether deal proneness moderates the relationship between app use and perceived shopping value.Design/methodology/approach A sample of 427 French consumers took part in an online survey inquiring about a recent shopping experience. The authors compared customers who used a retailer app during their shopping experience with those who did not. Mediation and moderated mediation using PROCESS were performed to identify whether retailer app use improves loyalty intentions through perceived shopping value, with deal proneness used as a moderator.FindingsThe results show a positive and direct effect of retailer app use on loyalty. The effect is also mediated by utilitarian and hedonic shopping values. The authors also highlight the fact that deal proneness moderates the mediation effect of both utilitarian and hedonic shopping values between retailer app use and loyalty. More specifically, retail app use significantly increases shopping value for deal-prone customers.Originality/value In the age of omnichannel retailing, this study offers potential contributions to improve the theoretical knowledge of the impact of retailer apps on retailer–customer relations, helping businesses to develop and implement appropriate app-related strategies.
Extensional Setting of Hainan Island in Mesoproterozoic: Evidence from Granitic Intrusions in the Baoban Group

The Mesoproterozoic Baoban Group is the oldest basement in Hainan Island and has played an important role in Columbia (Nuna) supercontinent reconstructions. The Mesoproterozoic granitic intrusions in the Baoban Group are the most widely‐exposed Precambrian magmatic rocks and are the key to understanding the tectonic settings of Hainan Island and its relationship with the South China Block and the Columbia supercontinent. New LA‐ICP‐MS zircon U‐Pb dating on three mylonitic granite samples from the Tuwaishan and Baoban areas yield ages ranging from 1447 Ma to 1437 Ma, representing the absolute timing of the emplacement of the granitic intrusions. Combined with previously published geochronological data for rocks from the Baoban Group and regional mafic intrusions, it is concluded that the Baoban Group formed at 1460–1430 Ma, coeval with the emplacement of the granitic and mafic intrusions. New in‐situ zircon Lu‐Hf isotope analyses for the three mylonitic granite samples yielded positive ∊Hf(t) values, ranging from +0.49 to +8.27, with model ages ( TDMC ) ranging from 2181 Ma to 1687 Ma, suggesting that the granitic intrusions originated from a mixed source of Paleoproterozoic crust with juvenile crust. New zircon trace element data show characteristics of high Th/U values of 0.24–1.50, steep slopes from LREE to HREE and negative Pr, Eu anomalies with positive Ce, Sm anomalies, representing typical magmatic zircons formed in continental crust. Compared with available magmatic and detrital zircon ages from Precambrian rocks in the Cathaysia Block, Yangtze Block and western Laurentia, it is inferred that Hainan Island was separated from both the Cathaysia Block and the Yangtze Block, instead being connected with western Laurentia in the Columbia supercontinent. Considering the decreasing tendency of basin deposition time along the western margin of Laurentia, it is proposed that Hainan Island was located to the north or northwest of the Belt‐Purcell Supergroup, along the western margin of Laurentia, during the breakup of the Columbia supercontinent.

Semi-solid Processing of Engineering Alloys by a Twin-screw Rheomoulding Process

Abstract Based on the extensive experience in injection moulding of polymeric materials, a twin-screw rheomoulding process has been developed in our laboratory for near net-shape production of engineering components. The rheomoulding equipment consists of a liquid metal feeder, a twin-screw extruder with closely intermeshing, self-wiping and co-rotating screws, a shot assembly and a central control unit. The fluid flow in the twin-screw rheomoulding process is characterised by high shear rate and high intensity of turbulence. The experimental results of rheomoulded Sn–15wt. % Pb and Mg–30wt. % Zn alloys have demonstrated that the twin-screw rheomoulding process is capable of producing small and near mono-sized solid particles distributed uniformly in a fine-grained eutectic matrix. Compared with other existing semi-solid metal processing techniques, the twin-screw rheomoulding process has the following advantages: small and spherical solid particles of near mono-size, chemical and microstructural uniformity throughout the component, accurate control over a large range of solid volume fractions, lower overall component cost due to low cost of feedstock materials, and shorter cycle time.
Workshop on Blood Loss Quantification in Obstetrics: Improving Medical Student Learning through Clinical Simulation

Purpose: To assess whether a clinical simulation-based obstetric blood loss quantification workshop for medical undergraduate trainees improves theoretical–practical knowledge, along with self-assurance and self-confidence. Methods: This was a quasi-experimental pre-post learning study conducted at the Gynaecology and Obstetrics Unit of the Hospital Gregorio Marañón, Madrid, Spain. Participants were volunteer students in their fourth year of a 6-year degree course in Medicine. The study period was divided into the stages: pre-workshop, intra-workshop, 2 weeks post-workshop and 6 months post-workshop. In the pre-workshop stage, students completed a brief online course in preparation for the workshop. The effectiveness of the workshop was assessed through multiple choice tests and self-administered questionnaires. Data were compared between time-points using statistical tests for paired samples. Results: Of the 142 students invited (age 21.94 ± 3.12 years), 138 accepted the offer of the workshop (97.2%), and 85.4% had no experience in managing blood loss. Between the stages pre- and 2 weeks post-workshop, significant improvements were observed in theoretical–practical knowledge (μ = 1.109), self-assurance and self-confidence. At the 6 months post-workshop stage, theoretical–practical knowledge diminished compared with 2 weeks post-workshop, returning to pre-workshop levels, while self-assurance and confidence failed to vary significantly in the longer term. Conclusions: The obstetric workshop improved theoretical–practical knowledge and the self-assurance and confidence of the medical students. Results 2 weeks post-workshop were maintained up until 6 months after the training intervention. The clinical simulation-based workshop was perceived by the students as useful and necessary.
