Soft X-ray absorption spectroscopy in the low-energy region explored using an argon gas window
Authors: Nagasaka Masanari 
Published: May 2020

The soft X-ray region below 200 eV is important for investigating chemical and biological phenomena since it covers K-edges of Li and B and L-edges of Si, P, S and Cl. Helium gas is generally used as the soft X-ray transmission window for soft X-ray absorption spectroscopy (XAS) under atmospheric conditions. However, the helium gas window cannot be applied to XAS in the low-energy region since transmitted soft X-rays mostly consist of high-order X-rays due to the low transmission of first-order X-rays. In this study, the argon gas window is proposed as a new soft X-ray transmission window in the low-energy region. High-order X-rays are removed by the absorption of the Ar L-edge (240 eV), and first-order X-rays become the major contribution of transmitted soft X-rays in the low-energy region. Under atmospheric argon conditions, the double-excitation Rydberg series of helium gas (60 eV), Si L-edge XAS of an Si3N4 membrane (100 eV) and S L-edge XAS of dimethyl sulfoxide gas (170 eV) are successfully measured, indicating that the argon gas window is effective for soft X-ray transmission in the low-energy region from 60 eV to 240 eV.
Financial statement comparability in the extractive industry
Authors: Smith Christelle , Venter Elmar R. 
Published: May 2020

Purpose
This paper aims to investigate financial statement comparability in the extractive industry. This paper focuses on the extractive industry because International Financial Reporting Standards (IFRS) contain limited guidance on the accounting treatment for exploration and evaluation (E&E) costs and IFRS 6 – Exploration for and Evaluation of Mineral Resources allowed firms to continue with existing divergent accounting treatment of E&E costs.

Design/methodology/approach
The authors use data from Australia, a country that adopted IFRS in 2005 with a large extractive industry. They also compare changes in cross-country comparability around the IFRS adoption date between Australian firms and adopters relative to Australian firms and non-adopters to better isolate changes in comparability that are attributable to the adoption of IFRS from other sources that are not related to the adoption of IFRS. The authors measure comparability consistent with De Franco et al. (2011) where financial statements are comparable when two firms produce similar accounting amounts for similar economic events.

Findings
For non-extractive industry firms, the authors find the comparability of financial statements of Australian firms increased with other adopters and that this increase was relatively greater than the increase with non-adopter firms. This evidence is consistent with comparability benefits associated with the adoption of IFRS. However, for extractive industry firms, the authors do not find a significantly greater increase in the comparability of financial statements of Australian firms with adopters relative to the increase with non-adopters, suggesting that the increase is likely not associated with the adoption of IFRS. In additional analysis, they find that following IFRS adoption non-extractive Australian firms have greater within-country comparability relative to extractive Australian firms, while there was no difference in the pre-adoption period.

Originality/value
The evidence suggests that the divergent practices for E&E costs under IFRS 6 and the lack of an accounting standard that deals with matters relating to the extractive industry hinder the comparability of financial statements in this industry.
The creative industries and degree apprenticeships: the benefits and challenges of adoption for small and micro businesses
Authors: Riley Tim 
Published: May 2020

PurposeThe purpose of this paper is to identify the needs and receptiveness of the creative industry sectors, in particular small and micro businesses, in respect of the adoption and development of degree apprenticeships. In addition, the paper aims to identify employers' barriers to entry into such programmes.Design/methodology/approachDue to the lack of knowledge of degree apprenticeships, an ‘explain and respond’ method was adopted, where a comprehensive explanation of degree apprenticeships and the process for delivery was given to respondents. This enabled them to ask questions and give informed and knowledgeable response to interview questions.FindingsParticipants in this research were generally positive about the integration and adoption of degree apprenticeships into their businesses. However, they suggest that the rigid procedure set by the Institute for Apprenticeships makes embarking on the process of developing standards and adopting degree apprenticeships difficult, time-consuming and impracticable for businesses of their size and in these sectors. This has implications for addressing skills shortages and diversity that stands to endanger the continued success of the creative industries.Originality/valueLittle research has been conducted into the viability of degree apprenticeships for creative industries, particularly non-levy paying small and micro businesses.

Published: May 2020

PurposeThe purpose of this study is to develop and test a theoretical model of Fairtrade buying behavior that supports Sustainable Development Goals (SDGs) by addressing the nexus between just-world beliefs, along with the normative influences, self-identity and altruistic values.Design/methodology/approachA conceptual framework on the influence of just-world beliefs for Fairtrade purchase intentions is proposed to analyze the role of just-world beliefs on the effects of normative influences and altruistic values for the intention to purchase Fairtrade products that support SDGs. These conceptualizations are empirically tested on a representative sample of 217 consumers.FindingsJust-world beliefs play a central role in the purchase intention by having a direct effect on purchase intention and an indirect effect mediated by personal norms and self-identity. They partially mediate the effects of altruistic values and social norms on the purchase intention of Fairtrade products that support SDGs.Originality/valueThe research provides a better understanding of the influences of these contextual variables on ethical consumption and contributes to both the theory and practice of how businesses can achieve SDGs. The psychological rationale of just-world beliefs provides a new approach to marketing strategy and communication aimed at increasing purchase intention of Fairtrade products that support the fundamental goals of the UN sustainable development.

AbstractThis study aimed to investigate the effects of different NaCl content and drying temperatures on the lipid oxidation, protein oxidation, and physical properties of dry‐cured chicken. In the final product, lipid oxidation, protein oxidation, and physical properties were significantly affected by NaCl and temperature. Increased NaCl content and temperature led to significantly increased level of indicators including conjugated diene, thiobarbituric acid reactive substances, and carbonyl contents (P < 0.05). Conversely, the sulfhydryl contents and surface hydrophobicity significantly decreased (P < 0.05). Results of sodium dodecyl sulfate polyacrylamide gel electrophoresis further indicated that NaCl and temperature affected protein oxidation and degradation. According to the drying curve, the main factor affecting the drying time was the drying temperature and a slower rate of moisture loss occurred in samples with higher NaCl content. Moreover, due to the effects of temperature on lipid and protein oxidation and moisture diffusion, the hardness and shrinkage ratio increased with temperature.Practical ApplicationDry‐cured chicken is a kind of air‐dried meat product. During actual production of dry‐cured chicken, its physicochemical characteristics (e.g., lipid and protein oxidation and texture) are affected by NaCl content and drying temperature. In this study, the NaCl content and drying temperature were found to promote lipid and protein oxidation and have significant effects on texture properties. Therefore, the NaCl content and drying temperature should be controlled to improve the quality of dry‐cured chicken.
Effects of 5‐HT2A receptor stimulation on economic demand for fentanyl after intermittent and continuous access self‐administration in male rats

Published: May 2020

AbstractThe relative value of and motivation for abused drugs often increases with drug experience and differs based on drug availability. Here, we determined how different intake patterns of fentanyl, a μ‐opioid agonist, alter economic demand for fentanyl and how 5‐HT2A receptor stimulation affects economic demand for fentanyl. We used a within‐session demand threshold procedure to characterize changes in economic demand for fentanyl before and after intermittent or continuous access schedules. We subsequently tested the acute effects of 5‐HT2A receptor stimulation with psychedelic 2,5‐dimethoxy‐4‐iodoamphetamine (DOI) on economic demand for fentanyl. Extended fentanyl experience with both intermittent and continuous schedules increased fentanyl consumption at low cost (Q0), increased total fentanyl consumption, and decreased demand elasticity (α), indicating both schedules elevated motivation to self‐administer fentanyl. Overall, the two schedules produced similar alterations in economic demand for fentanyl, although low‐cost consumption (Q0) increased more in the continuous access group. Systemic injections of DOI (0.0‐0.4 mg/kg, i.p.) dose‐dependently produced economic demand changes in the opposite direction produced by fentanyl experience. DOI decreased motivation (increased “α”), decreased Q0, and decreased total fentanyl consumption. The selective 5‐HT2A antagonist, M100907 (0.3 mg/kg, i.p.), blocked the effects of DOI, indicating that DOI is acting through 5‐HT2A receptors to alter economic demand for fentanyl. In an economic food demand experiment, DOI (0.4 mg/kg) also increased demand elasticity and reduced food consumption. These results demonstrate that both intermittent and continuous fentanyl experience raise the economic demand for fentanyl, and acute 5‐HT2A receptor activation reduces economic demand for fentanyl and food.
Overview of the horseflies (Diptera: Tabanidae) of South Africa: assessment of major collections for spatiotemporal analysis

Published: May 2020

AbstractTabanidae, commonly known as horseflies, is a large, cosmopolitan family with approximately 4400 described species, of which about 400 occur in southern Africa. Both sexes feed on nectar or pollen and some species are important pollinators. Females usually require a bloodmeal to produce eggs, implicating them as vectors of disease‐causing agents. Despite their importance, they have been largely neglected by science, especially in the Afrotropics. In this study, we aimed to elucidate some fundamental spatiotemporal aspects of horsefly biology in South Africa by centralising digitised data from the major natural history museums in the region. Approximately 6 000 records have been digitised and collated into a Specify database from an approximate 17 000 specimens housed in 10 museums in the region. The collections from the 10 institutions, including six collections in neighbouring countries are briefly discussed. Spatiotemporal analysis according to biomes (Albany thicket, desert, forests, fynbos, grassland, Indian Ocean belt, Kalahari savannah sub‐biome, Central Bushveld sub‐biome, Lowveld savannah sub‐biome, Nama Karoo and Succulent karoo) revealed baseline information regarding their biology within the biomes. The majority of the records are from north eastern KwaZulu‐Natal, followed by Kruger National Park and areas surrounding Cape Town, indicative of uneven sampling. The database is represented by a total of 195 species of which 83 species were recorded in only one biome, with grassland home to 28% of the biome endemic species. A species list to the region, supplemented by records from previous authors, totals to 203 species occurring in the region. Future studies should aim to digitise the remaining specimens in order to create species pages with brief descriptions, high‐resolution photographs, distribution maps and spatiotemporal patterns available online.

Published: May 2020

BackgroundThe diagnosis of Asherman syndrome, or ‘intra‐uterine adhesions’ is often overlooked when the symptoms of amenorrhea and hematometra are missing.AimsThis audit reviews the clinical data of a large cohort of patients treated by a single operator.Materials and MethodsFrom July 1998 till the end of December 2017, 423 patients with intra‐uterine adhesions were treated by a single operator. Clinical information was obtained by review of the medical files and phone interviews.ResultsAmenorrhea was recorded in 163/423 patients (38.5%), 225/423 (53.2%) patients did not have amenorrhea and for 35/423 (8.3%) patients the information was missing. A hematometra was documented in 19/423 (4.5%) patients. Pregnancy was achieved in 215/246 (87.4%). Patients with stage II disease did best with a pregnancy rate of 94.5% (P = 0.029).ConclusionAsherman syndrome should be considered in any woman with a history of miscarriage or postpartum curettage who then fails to conceive again.
Test‐ or judgement‐based school track recommendations: Equal opportunities for students with different socio‐economic backgrounds?
Authors: van Leest Anne , Hornstra Lisette , van Tartwijk Jan , van de Pol Janneke 
Published: May 2020

BackgroundThere are concerns that school track recommendations that are mostly based on teachers’ judgements of students’ performance (‘judgement‐based recommendations’) are more biased by students’ SES than school track recommendations that are mostly based on standardized test results (‘test‐based recommendations’). A recent policy reform of the Dutch educational system has provided us the unique opportunity to compare the effects of students’ SES on these two types of track recommendations.AimsThe aim of this study was to examine the differences between test‐based and judgement‐based recommendations regarding the direct and indirect effect of students’ SES at student level and school level.SampleThe sample consisted of 8,639 grade 6 students from 105 Dutch primary schools.MethodsData were analysed using two‐level multilevel mediation models.ResultsTrack recommendations were higher for high‐SES students. This was mostly due to differences in students’ prior performance. SES also had a small, direct effect on judgement‐based, but not on test‐based recommendations. The effects were partly situated at school level.ConclusionOverall, the results indicated that teachers based their track recommendations mostly on students’ prior performance without being biased by students’ SES.

Published: May 2020

AbstractObjectivesTo investigate the effect of defined versus undefined periodontal maintenance after implant therapy on the prevalence of peri‐implant complications.Material and MethodsTwo hundred patients who underwent dental implant therapy in the National Dental Centre Singapore (NDCS) from 2005 to 2012 were recruited. One hundred patients had regular periodontal maintenance (defined maintenance programme group, DMP), and the other 100 patients had no documentation of periodontal maintenance (undefined maintenance programme group, UMP). Full‐mouth bleeding scores (FMBS), periodontal probing depths (PPD) and peri‐implant probing depths (PiPD) were evaluated within 6 months of prostheses delivery (T0) and at re‐examination (T1). Peri‐implant bone level changes were analysed radiographically.ResultsThe mean follow‐up time was 6.8 years. Five out of 289 implants were lost (cumulative survival rate = 98.3%). 6.0% of DMP patients and 20.0% of UMP patients had peri‐implantitis (p = .003). Peri‐implantitis was defined as bleeding on probing, increase in PiPD and peri‐implant bone loss ≥ 0.5 mm. At the implant level, 4.0% of the DMP group implants and 17.2% of the UMP group implants were diagnosed with peri‐implantitis (p = .0003). One implant in the DMP group and 13 implants in the UMP group had bone loss ≥ 2 mm (p < .0001). Multivariate regression showed that absence of regular maintenance (OR = 0.24, p = .003) was significantly associated with peri‐implantitis.ConclusionsRegular periodontal maintenance was associated with a lower prevalence of peri‐implantitis and peri‐implant bone loss. Patients with treated periodontitis without regular maintenance after implant placement were at higher risk for developing peri‐implantitis.

Published: May 2020

AbstractObjectivesThe objective of this in vitro study was to assess the accuracy of fully guided implant placement following virtual implant planning based on MRI.Material and MethodsSixteen human cadaver hemimandibles with single missing teeth (n = 3), partially edentulous (n = 6) and edentulous situations (n = 7) were imaged using MRI. MRI and optical scans obtained with an intraoral scanner, were imported into an implant planning software. Virtual prosthetic and implant planning were performed regarding hard‐ and soft‐tissue anatomy. Drill guides were manufactured, and fully guided implant placement was performed. Buccal and lingual bone and implant nerve distance were measured by three examiners in preoperative MRI and postoperative CBCT. The implant position was assessed using a software for deviation of implant positions displayed in CBCT and optical scans, respectively.ResultsMRI displayed relevant structures for implant planning such as cortical and cancellous bone, inferior alveolar nerve and neighboring teeth. Implant planning, CAD/CAM of drill guides and guided implant placement were performed. Deviations between planned and actual implant positions in postoperative CBCT and optical scans were 1.34 mm (SD 0.84 mm) and 1.03 mm (SD 0.46 mm) at implant shoulder; 1.41 mm (SD 0.88 mm) and 1.28 mm (SD 0.52 mm) at implant apex, and 4.84° (SD 3.18°) and 4.21° (SD 2.01°). Measurements in preoperative MRI and postoperative CBCT confirmed the compliance with minimum distances of implants to anatomical structures.ConclusionsRelevant anatomical structures for imaging diagnostics in implant dentistry are displayed with MRI. The accuracy of MRI‐based fully guided implant placement in vitro is comparable to the workflow using CBCT.

Published: May 2020

AbstractSquare Root Carry Select Adder (SQRT‐CSLA) is accomplishing the noteworthy attention in the arena of VLSI (Very‐Large‐Scale Integration) systems as it can process the computations with high speed. Though the current trending SQRT‐CSLA adder designing techniques are effective in various performance metrics, there is a possibility to improve the design addressing various performance metrics. This article proposes CSLA architecture by employing Zero Finding Logic using the Logic optimization technique (ZFCLOT). CSLA using ZFCLOT is designed, simulated, and synthesized using 90 nm cadence tools. CSLA using ZFCLOT achieves an area efficiency of 46.127% and a power efficiency of 48.4% as against to SQRT‐CSLA.

Published: May 2020

ABSTRACTThis review examines supply chain risk publications across nine prestigious management, operations, and supply chain journals with respect to exploring trends and emerging topics. Using a refined set of keywords, we extract and filter the most relevant supply chain risk management (SCRM) articles from Scopus between 2001 and 2019. Unlike previous reviews of the SCRM literature, our methodology utilizes both bibliometric and cocitation analyses of publications in selective management and operations and supply chain management journals. In addition to analyzing the current state of the SCRM literature via bibliometric analysis, we delve deeply into the clusters of literature informing SCRM studies through a cocitation analysis. By conducting a text analysis on these clusters, we identify the main themes and provide insights regarding article relevance, theoretical frameworks, and methodologies for each cluster. In addition, we categorize the themes within each cluster into three main groups of matured, developing, and emerging. Based on the identified categories, we provide detailed discussions on the promising avenues for research and practice in three main areas of sustainable SCRM, behavioral SCRM, and nascent methodologies and theories in SCRM studies. Finally, we dedicate a section in our review to discussing the direction of SCRM research during and after the coronavirus disease 2019 era.
Trade uncertainties and the hedging abilities of Bitcoin
Authors: Bouri Elie , Gkillas Konstantinos , Gupta Rangan 
Published: May 2020

AbstractIn this paper, we first estimate the monthly realised correlation, based on daily data, between stock returns of the United States (US) and Bitcoin returns. Then, we relate the realised correlation over the period October 2011 to May 2019 with a news‐based measure of the growth of trade uncertainty of the US. Our results show that the realised correlation is negatively impacted by increases in trade uncertainty, which continues to hold under alternative robustness checks, suggesting that Bitcoin can act as a hedge relative to the conventional stock market in the wake of heightened trade policy‐related uncertainties, and provide diversification benefits for investors.
