Crystal structure of Re‐substituted lanthanum tungstate La5.4W1−yReyO12–δ (0 ≤ y ≤ 0.2) studied by neutron diffraction

A precise determination of sample composition and water uptake of La6−xWO12−δ (0.4 ≤ x ≤ 0.8) and Re-substituted La5.4W1−yReyO12−δ (0 ≤ y ≤ 0.2) lanthanum tungstate is carried out. Sample compositions and water uptake were determined by electron probe micro-analysis and thermogravimetry, respectively. A single-phase region of Re-substituted lanthanum tungstates is reported. The crystal structure of two selected specimens produced by the citrate-complexation route based on the Pechini method, namely La5.4WO12−δ and La5.4W0.8Re0.2O12−δ, was investigated by neutron diffraction in the temperature range 1.5 ≤ T ≤ 1200 K. The structural model for lanthanum tungstates is validated, according to which the Wyckoff site shared by La and W (Fm{\overline 3}m space group, 24d site) is split with half-site occupancies (Fm{\overline 3}m space group, 48h site). Replacement of W by up to 20 mol% Re does not change the lattice structure, and Re atoms substitute for W statistically in both 4a and 48h Wyckoff sites of the Fm{\overline 3}m space group, as shown by combining the average neutron scattering length procedure, thermogravimetry and electron probe micro-analysis. Using the Willis and Pryor approach to anisotropic displacement parameters it is shown that the remaining static disorder in the unit cell found in La5.4WO12−δ and La5.4W0.8Re0.2O12−δ structures is comparable, when the Fm{\overline 3}m space group with split 48h site is employed. Through the estimation of the Debye temperature for both compounds, extracted from the analysis of thermal expansion coefficients and from the Willis and Pryor approach, anion anharmonic vibrations like those in yttria-stabilized zirconia are proven to exist in LaWO for the first time.
Adoption and Usage of E-Grocery Shopping: A Context-Specific UTAUT2 Model

In order to determine how sustainable online grocery shopping is as a practice, it is crucial to have an in-depth understanding of its drivers. This paper therefore validates the Unified Theory of Acceptance and Use of Technology (UTAUT2) in the context of e-grocery and enriches it with five constructs. We exploit a self-administered survey among 560 customers of two Belgian supermarkets and test the model by means of hierarchical multiple regression analysis. We do so not only for the full sample, but also for users and non-users separately. For the full sample, four of the five proposed context-specific constructs—namely, perceived risk, perceived time pressure, perceived in-store shopping enjoyment, and innovativeness—help better explain the intention to adopt or continue to use e-grocery services. In the subsamples, only perceived time pressure and innovativeness add explanatory power, and this only for non-users. In other words, the additional constructs primarily help discriminate between users and non-users. In addition, while the extended model outperforms the original UTAUT2 model for all three samples, the added value of the extended model does not so much lie in a higher explained variance, but rather in a more correct identification of the drivers of BI.
Punishing environmental offenders: criminal environmental sentencing in Louisiana, 2004-2014

ABSTRACT Despite growing interest in environmental/green crimes, little remains known about these offenses and how environmental offenders are punished in criminal cases. Much of what is known about the punishment of environmental offenders comes from studies that are now more than 25 years old. Further, many studies rely on aggregated US EPA data, which provides information about these cases nationally, but does not address potential variability in the punishment of environmental criminals in any particular state. To address these issues, this study examines state-level criminal punishments for environmental offenders in Louisiana for the years 2004–2014. The discussion also draws attention to estimating the potential frequency of environmental crimes and punishments in Louisiana. The results support contentions that environmental punishment are rare, that penalties in a handful of cases significantly skew the results, and that when extreme punishments are omitted, criminal punishments for environmental offenses are lenient in comparison to the potentially damaging consequences of those offenses.
Primary Fallopian Tube Carcinoma: Results of a Single-Institutional Retrospective Analysis of 17 Patients with Evaluation of Staging and Prognostic Factors

OBJECTIVE: Primary carcinoma of the fallopian tubes is one of the less common gynecological cancers. It constitutes (0.14-0.18%) of gynecological malignancies. Our study aimed to review the managing process of primary carcinoma of the fallopian tubes in the mono-center institute and to identify prognostic factors impacting survival. STUDY DESIGN: A retrospective cohort study regarding patients with fallopian tube carcinoma treated between July 1991 and December 2005 was identified at the Tunisian anticancer institute “Salah Azaiez”. During this period, we have identified 17 patients. Data such as age, gravidity and parity, menopausal condition, symptoms reported by the patient on presentation, adjuvant therapy, stage of illness, surgical intervention, pathological findings, tumor recurrence, and previous surgical procedures were obtained from the patients’ reports. RESULTS: The average age at the time of diagnosis was 58 years. Fourteen of the included patients were postmenopausal. Surgery was the initial therapy for 15 patients. Optimal cytoreductive surgery was achievable in seven patients with no residual tumors. Histologic examination revealed that serous adenocarcinoma type was the predominant type. Two were in stage I and, four were in stage II; seven were in stage III and four in stage IV. The median follow-up time was 24 months. At the time of the final analysis, 11 patients died of disease. 5-year OS, DFS was 21% and 37% respectively. In our study, only the residual tumor was a significant prognostic factor predicting survival. CONCLUSION: Complete optimal surgery with no residual tumor was the main goal of the surgeon to improved survival in primary fallopian tube carcinoma.
Attitude coordinated output feedback control based on event triggering for multiple spacecrafts

ABSTRACT In this paper, the attitude cooperative output feedback control problem for multiple spacecrafts with limited communication resources is considered. First, a dynamic Event-Triggered Extended State Observer (ETESO) is developed for multiple spacecrafts to estimate the unmeasurable angular velocity, which can reduce the data-releasing rate. Second, a new distributed dynamic event-triggered communication scheme is proposed, which only adopts discrete information of neighbouring spacecrafts. Based on two independent dynamic event-triggered strategies, network load is reduced, and continuous communication between spacecrafts is avoided. The validity of the proposed controller is demonstrated by simulations.
Factors Influencing Professionals and Contractors’ Resistance Behaviours towards Sustainable Construction Practices in Nigeria

This study examined the factors influencing construction professionals and contractors’ resistance behaviours towards sustainable construction practices in Nigeria. 56 variables identified from literature were categorised into four main factors. Questionnaire was designed based on the extracted variables and distributed to construction professionals and contractors in South-East Nigeria. The data generated through the questionnaire survey were analysed using Statistical Package for Social Sciences (SPSS) Software. The result revealed that industry, policy, human, and environment factors were significantly influencing professionals and contractors’ resistance behaviours to implementation of sustainable construction practices. However, the Mean Score Index result revealed that policy factors with an average MSI of 4.68 exert the greatest influence on professionals’ and contractors’ resistance behaviours. The overall result showed that all the variables have significant influences on professionals’ and contractors’ resistance behaviours, but five sub-factors (limited knowledge and awareness, additional cost of change, the prevailing economic condition, incompatibility of change process and organisational culture, and laws and regulations) each with an average MSI of 5.00 have the greatest individual influences on construction stakeholders’ resistance behaviours towards sustainable construction practices in Nigeria. The Mann-Whitney U Test result affirmed that there is no significant difference (p>0.05) between the rankings of professionals and contractors on the factors influencing their resistance behaviours. In view of this, the study raised concern about the training routes of the construction practitioners, conventional construction practices and existing policy and legislative frameworks including government commitment towards implementing sustainable construction practices in Nigeria.
“Teacher education is a good choice, but I don’t want to teach in schools.” An analysis of university students’ career decision making

ABSTRACT This paper reports qualitative findings from a large study on Indonesian teacher education students’ career aspirations. The participants were 133 final-year undergraduate students who entered teacher education programmes with no intentions to teach in schools or had intentions to teach only for a short period upon graduation before pursuing another career. Their motivations to choose teacher education programmes are analysed from the perspectives of the social learning theory of career decision making. The most popular reasons were good reputation of the universities, convenient campus location, and comparatively low tuition fees for the programme. Provision of scholarship was also an attraction. Career possibilities outside teaching was another key reason for entering the programme. While a few students perceived teacher education as a stepping stone to pursue another career, some did not have any specific plan but followed their parents’ advice and friends’ choice of study. Participants’ perceptions about teacher education programmes and teaching are discussed along with implications.
The use of interprofessional simulation interventions in medical student education: A scoping review

Introduction : Simulation is commonly used by health and education institutions to facilitate interprofessional learning (IPL). The use of simulation in IPL is resource intensive. Evidence of what works, and with whom, is important to inform practice, policymaking and further research. The aim of this scoping review was to summarise the existing literature on IPL involving medical students, where simulation was the teaching modality. This review examined a variety of simulation-based interventions used to teach IPL to medical students and identified key features and outcomes. Methods : The databases Pubmed, Medline, EMBASE and PsychINFO were searched using the terms related to medical student and simulation combined with interprofessional. Included articles involved medical students alongside a student or practitioner from at least one other health profession taking part in at least one simulation session. Data extraction was performed by two authors using a standardised form. Results : It emerged that simulations of medical emergencies were the most common format to deliver IPL interventions. Most studies evaluated the success of their IPL intervention using the Readiness for Interprofessional Learning Scale (RIPLS). Conclusion : All studies were successful in improving student attitudes towards IPL and interprofessional collaboration when these were measured outcomes. Formal team training prior to simulation is effective in improving teamwork skills. IPL interventions with participants from a greater mix of professions have more positive results.
Transparency in the News: The Impact of Self-Disclosure and Process Disclosure on the Perceived Credibility of the Journalist, the Story, and the Organization

ABSTRACT An experimental study was conducted to see what impact varying the level of self-disclosure by a journalist, as well as providing information about why and how a story is being covered, has on the perceived credibility of the journalist, the story, and the organization for which the journalist works. A study was conducted that included 885 participants from the United States. Results indicate the group that saw a picture of the journalist, a low level of disclosure regarding the journalist, and information about why and how the story was being covered rated the journalist, story, and organization highest in terms of perceived credibility. These findings indicate that traditional news organizations, when it comes to building audience credibility, should consider including at least some information about the journalist, and perhaps, more importantly, information about why and how the story is being covered.
Influence of lighting environment on social preferences in sticklebacks from two different photic habitats. II. Shoaling and mate preferences of lab-bred fishes

Abstract Different environmental conditions may lead to diverse morphological, behavioral, and physiological adaptations of different populations of the same species. Lighting conditions, for example, vary vastly especially between aquatic habitats, and have been shown to elicit adaptations. The availability of short-wave ultraviolet (UV) light is especially fluctuating, as UV wavelengths are attenuated strongly depending on water properties. The island of North Uist, Scotland, comprises 2 differential habitat types, tea-stained and clear-water lakes, varying considerably in UV transmission. In previous studies, wild-caught 3-spined stickleback Gasterosteus aculeatus populations (3 populations of each habitat type) were tested with respect to their shoaling and mate preferences for fish viewed under UV-present and UV-absent conditions. The results revealed a habitat-dependent preference of UV cues during shoal choice (tea-stained populations: preference for UV-absent condition in tea-stained water; clear-water populations: no preference in clear-water) but an overall preference for UV-present conditions during mate choice. To assess genetic influences on these behavioral patterns, similar experiments were conducted with lab-bred F1-generations of the same stickleback populations that were raised in a common environment (i.e. standardized clear-water conditions). Offspring of sticklebacks from tea-stained lakes tended to prefer shoals viewed under UV-absent conditions (only in tea-stained water), while sticklebacks from clear-water lakes showed a significant preference for the shoal viewed under UV-present conditions in clear-water but not in tea-stained water. Mate-preference experiments demonstrated that females from the tea-stained lakes significantly preferred and females from the clear-water lakes preferred by trend the male viewed under UV-present conditions in the clear-water treatment. The results for both shoaling- and mate-preference tests were largely similar for wild-caught and lab-bred sticklebacks, thus hinting at a genetic basis for the preference patterns.
Moisture Variation with Cloud Effects during a BSISO over the Eastern Maritime Continent in a Cloud-Permitting-Scale Simulation

Despite the great importance of interactions between moisture, clouds, radiation, and convection in the Madden-Julian Oscillation, their role in the boreal summer intraseasonal oscillation (BSISO) has not been well established. This study investigates the moisture variation of a BSISO during its rapid redevelopment over the eastern Maritime Continent through a cloud-permitting-scale numerical simulation. It is found that moisture variation depends closely on the evolution of clouds and precipitation. Total moisture budget analysis reveals that the deepening and strengthening (lessening) of humidity before (after) the BSISO deep convection are attributed largely to zonal advection. In addition, the column moistening/drying is mostly in phase with the humidity and is related to the maintenance of BSISO.An objective cloud-type classification method and a weak temperature gradient approximation are used to further understand the column moistening/drying. Results indicate that elevated stratiform clouds play a significant role in moistening the lower troposphere through cloud water evaporation. Decreases in deep convection condensation and re-evaporation of deep stratiform precipitation induce moistening during the development and after the decay of BSISO deep convection, respectively. Meanwhile, anomalous longwave radiative heating appears first in the lower troposphere during the developing stage of BSISO, further strengthens via the increase of deep stratiform clouds, and eventually deepens with elevated stratiform clouds. Accordingly, anomalous moistening largely in phase with the humidity of BSISO toward its suppressed stage is induced via compensated ascent. Owing to the anomalous decrease in the ratio of vertical moisture and potential temperature gradients, the cloud-radiation effect is further enhanced in the convective phase of BSISO.
Statistical Quality Control Charts Based on Hyper-Geometrically Distributed Data

In some production and administrative processes, the occurrence of certain events is best described by a hyper-geometric distribution, which in turn should be pictorially depicted by what should be called a “hyper-geometric chart (Hg-chart)” in the field of Statistical Quality Control (SQC). However, this has never been the practice, since the existence of such a chart is absent; as such, prompting administrators and process engineers to make use of already existing charts for approximately depicting hyper-geometric processes. In this article, an SQC chart for any hyper-geometric process has been developed for the total number of events in a fixed number of units. This chart has been referred to as the Hg-chart. The center line (CC), lower control limit (LCL) and the upper control limit (UCL) have been obtained for the proposed chart with a sketch of how the proposed chart should be if used for simulation. It has been recommended that simulation should be used to test the proposed chart as this could prove to be more efficient and appropriate for describing hyper-geometric data rather than using an inappropriate chart to be an approximation for solving the problem.

A Simulation Study to Understand the Efficiency Analysis of Multiple Injectors for the Double Compression Expansion Engine (DCEE) Concept

Heavy-duty vehicles face increasing demands of emission regulations. Reduced carbon-dioxide (CO 2 ) emission targets motivate decreased fuel consumption for fossil fuel engines. Increased engine efficiency contributes to lower fuel consumption and can be achieved by lower heat transfer, friction and exhaust losses. The double compression expansion engine (DCEE) concept achieves higher efficiency, as it utilizes a split-cycle approach to increase the in-cylinder pressure and recover the normally wasted exhaust energy. However, the DCEE concept suffers heat losses from the high-pressure approach. This study utilizes up to three injectors to reduce the wall-gas temperature gradient rendering lower convective heat losses. The injector configuration consists of a standard central injector and two side-injectors placed at the rim of the bowl. An increased distance from side-injector to the wall delivered lower heat losses by centralizing hot gasses in the combustion chamber. Computational fluid dynamics (CFD) simulations investigated two different piston bowls, in a heavy-duty diesel engine, to obtain in-cylinder conditions for one, two -and three-injector concepts. One-dimensional (1D) simulations then used the CFD data to obtain the complete efficiency analysis of the DCEE concept. The results showed that the three-injector case improved the brake thermal efficiency and reduced the heat transfer losses, compared to the two-injector and single-injector cases. In particular, the three-injector case resulted in a high indicated and brake thermal efficiency of 58.5 % and 54.2 %, respectively.
Blackwater Diving: An Exciting Window Into the Planktonic Arena and Its Potential to Enhance the Quality of Larval Fish Collections

“Blackwater diving,” or nighttime SCUBA diving in epipelagic environments, has become highly popular in recent years because lay participants encounter animals that are difficult and expensive to observe through other methods. These same observations can be priceless for researchers working with these species, so an interface between the scientific communities and recreational divers would be mutually beneficial. In this paper, we describe one such interface through the photography, collection, and DNA barcoding of larval fishes from the island of Hawaii. The images and videos from this activity provide an exciting window into the epipelagic environment and the way larval fishes appear and swim within it. Blackwater diving allows us to see the often-elaborate appendages and other specializations of these larvae as they appear in situ, prior to extensive net and fixation damage. However, blackwater diving remains an almost exclusively recreational pursuit, particularly popular among underwater photographers, who have little interest in (or object to) collecting specimens for scientists. Nonetheless, a logical next step is careful hand collection of specimens for scientific study. Growing numbers of recreational divers around the world have access to an otherwise expensive-to-research habitat. Here we present, for the first time, in situ and post-fixation photos of larval fishes that were hand collected and fixed in 95% ethanol by blackwater divers operating out of Kona, Hawaii, with DNA barcode identifications congruent with morphology and pigmentation where possible. With the right motivation, blackwater diving could augment research in the pelagic ocean and significantly enhance natural history collections and our knowledge of the larvae of marine fishes.
Narrative in VR journalism: research into practice

ABSTRACT In 2015 The Tow Center for Journalism produced a live-motion virtual reality (VR) journalism story on the Ebola outbreak in West Africa, ‘Secret Location’. They stated that this new form appeared to change how journalists must construct their stories. They also challenged the industry to explore the journalistic application of VR beyond ‘highly produced documentaries’ (Owen et al. 2015. “Virtual Reality Journalism.” Tow Centre. CJR. https://www.cjr.org/tow_center_reports/virtual_reality_journalism.php). We decided to make a short news VR film that explored the construction of this form of media and asked which narrative characteristic engaged the viewer to continue watching in a medium where the viewer was already immersed in the storyworld. Our findings suggest that even when the VR technology immerses the viewer into an illusion of presence, the traditional characteristics of narrative, character, plot, and subject remain of fundamental importance in the construction of a news story, and, it was the tension of what happens next, that is the plot, that was the strongest narrative driver in this short journalistic VR film. We also reflect on some issues raised in the production of the piece, such as the time taken, the limitations of creative editing and whether the expectations that VR raises might impact on the experience of viewing a VR news items.
