The state of IFRS in Africa
Authors: Tawiah Vincent 
Published: December 2019

PurposeThe purpose of this paper is to appraise existing literature on International Financial Reporting Standards (IFRS) in Africa. It covers all 54 African countries and their membership in regional and international accounting bodies.Design/methodology/approachThis paper uses qualitative research methods, including review and synthesis of a variety of archival materials.FindingsUnlike the numerous variations in IFRS adoption on other continents, IFRS countries in Africa have adopted the standards as issued by International Accounting Standard Board (IASB). However, most countries are slow to implement the ROSC (AA) recommendations for IFRS adoption due to lack of institutional and professional capacity. With regards to the unintended consequences, IFRS adoption has made international professional qualifications such as Association of Certified Chartered Accountants popular in Africa; hence, national accounting qualifications are not attractive to prospective accountants. Similarly, IFRS adoption has created a competitive advantage for the Big4 audit firms because companies in IFRS countries prefer the services of the Big4 to that of the local audit firms.Originality/valueIt is concluded that international organisations that recommend IFRS to Africa, such as the IFRS foundation, IMF and World Bank, should build the sustainable professional and institutional capacity of the countries before persuading them to adopt IFRS, because in Africa, adopting a law is easy but operationalising it has always been the challenge.
Entrepreneurial selling in context
Authors: Dalecki Linden 
Published: December 2019

Purpose
The purpose of this study is to provide a general review of the existing academic and practitioner literatures, pertaining to entrepreneurial selling with a view to articulate major entrepreneurial selling practices, patterns and principles that lead to entrepreneurial success and to propose two four-quadrant matrices.

Design/methodology/approach
The paper explores commonalities and distinctions in the entrepreneurial selling concepts articulated by Deutsch and Wortmann and Onyemah and Rivera-Pesquera – and relevant writings by Blank as well as Sarasvathy – are explored and analyzed.

Findings
It was found that the early stage entrepreneurial selling activities of founders – as a means of gleaning prospective customer feedback for product prototyping – form the core of contemporary entrepreneurial selling conceptualizations. Two provisional four-quadrant entrepreneurial selling matrices are proposed corresponding to the literature reviewed.

Research limitations/implications
It is hoped that the two four-quadrant matrices might serve as a springboard for future researchers interested in exploring entrepreneurial selling. The notion of preliminary selling as a valuable form of marketing research is also worthy of future research.

Practical implications
Given the extent to which the perspectives of entrepreneurship practitioners, clinical professors and consultants are cited and explored, manifold aspects of entrepreneurial selling are put forth. The various approaches to preliminary selling that are explored are of especially high value to practitioners.

Originality/value
This is the first paper to fully explore the commonalities and distinctions across the entrepreneurial selling conceptualizations developed by Deutsch and Wortmann, as well as by Onyemah and Rivera-Pesquera, and the first to propose a conceptual framework focused specifically on entrepreneurial selling.

Authors: Noorda Rachel L. 
Published: December 2019

Purpose
The purpose of this paper is to empirically test how company size affects the use of Scotland’s place brand in product branding by small and medium-sized enterprises (SMEs) in the book industry in Scotland.

Design/methodology/approach
This paper uses a mixed-method approach to investigate place brand adoption for product branding by SMEs in the Scottish book industry through the analysis of Scotland’s place brand identifiers in a corpus of 208 online book blurbs.

Findings
Results from the analysis show that, amongst SMEs in the Scottish publishing industry, smaller companies are more likely to use Scotland place brand identifiers in product marketing.

Originality/value
This is the first study to analyze book blurbs from a marketing perspective and it is one of the few articles on product-place co-branding. Additionally, branding in SMEs is a relatively new and uncharted area of research to which this study contributes, and branding in book publishing is also a scarcely researched area, to which this study offers new, empirical data about the relationship between place brands and product brands.

AbstractThe association of psoriasis with thyroid dysfunction has been investigated; however, it remains controversial. Some papers indicate it, and others do not. Thereby, we investigated the prevalence of thyroid dysfunction in patients with psoriasis vulgaris (PsV), psoriatic arthritis (PsA) and generalized pustular psoriasis (GPP), and the relationship between the severity of psoriasis with serum free triiodothyronine (fT3), free thyroxine (fT4) and thyroid‐stimulating hormone levels. Data on 85 psoriatic patients visiting our hospital from January 2015 to November 2017 (54 men and 31 women; 51 PsV, 23 PsA 23 and 11 GPP) were retrospectively analyzed. Fourteen percent of psoriatic patients had thyroid dysfunction. The percentage of patients with thyroid dysfunction was the highest in those with GPP (45% GPP, 13% PsA, 8% PsV). Patients with thyroid dysfunction demonstrated significantly higher Psoriasis Area and Severity Index scores and elevated serum C‐reactive protein (CRP) levels than those without thyroid dysfunction. A significant negative correlation was observed between the serum levels of CRP and fT3 (P = 0.0032,r = −0.4635). Our data indicate that thyroid dysfunction in patients with psoriasis is associated with inflammation caused by psoriasis.
Mating system and historical climate conditions affect population mean seed mass: Evidence for adaptation and a new component of the selfing syndrome in Clarkia

Published: December 2019

Abstract

The evolution of seed size may be influenced by intrinsic attributes of populations, such as mating system and extrinsic factors, such as climate. Several hypotheses propose that the evolution of self‐fertilization from an outcrossing progenitor will be accompanied by a reduction in seed size, but this prediction has not been rigorously tested. Many studies report that the mean seed size of populations or taxa is associated with long‐term climate conditions. Here, we examined the effects on seed size of both mating system and climate within a single genus.

In the California wildflower genus, Clarkia (Onagraceae), we sampled seeds from 58 populations representing three pairs of sister taxa; each pair included a predominantly outcrossing and a facultatively selfing taxon. We then examined the independent effects on population mean seed size of mating system, elevation, long‐term (30‐year) climate conditions, and climate anomalies (the deviation between conditions in the year of collection and the long‐term mean), focusing on maximum monthly temperature (Tmax), cumulative moisture deficit and cumulative precipitation (PPT) during Clarkia's growing season (fall, winter and spring).

In each taxon pair, the selfing taxon had smaller seeds than the outcrosser. Local, long‐term (1921–1980 and 1981–2000) mean Tmax, PPT and elevation were independently and negatively associated with seed size. Long‐term means for Tmax and PPT explain geographical variation in seed size better than climate anomalies in the year of collection.

Synthesis. We corroborated two key hypotheses concerning the drivers of geographical variation in mean seed size. Small seeds in Clarkia co‐evolve with selfing (although the mechanism remains elusive) and in response to chronically warm and wet conditions. The effect of long‐term mean precipitation on seed size differs qualitatively from the effect of precipitation anomalies; relatively large seeds are produced in populations experiencing wetter‐than‐normal years. Ongoing climate change may therefore generate conflicting selection on seed size in Clarkia: intensifying drought is likely to lead to an evolutionary increase in seed size due to its effects on seedling survivorship, while climate‐driven declines in pollinators or selection favouring more rapid reproduction may promote the evolution of self‐pollination, facilitating the evolution of smaller seeds.
CRISPR interference (CRISPRi) as transcriptional repression tool for Hungateiclostridium thermocellum DSM 1313
Authors: Ganguly Joyshree , Martin‐Pascual Maria , van Kranenburg Richard 
Published: December 2019

SummaryHungateiclostridium thermocellum DSM 1313 has biotechnological potential as a whole‐cell biocatalyst for ethanol production using lignocellulosic renewable sources. The full exploitation of H. thermocellum has been hampered due to the lack of simple and high‐throughput genome engineering tools. Recently in our research group, a thermophilic bacterial CRISPR–Cas9‐based system has been developed as a transcriptional suppression tool for regulation of gene expression. We applied ThermoCas9‐based CRISPR interference (CRISPRi) to repress the H. thermocellum central metabolic lactate dehydrogenase (ldh) and phosphotransacetylase (pta) genes. The effects of repression on target genes were studied based on transcriptional expression and product formation. Single‐guide RNA (sgRNA) under the control of native intergenic 16S/23S rRNA promoter from H. thermocellum directing the ThermodCas9 to the promoter region of both pta and ldh silencing transformants reduced expression up to 67% and 62% respectively. This resulted in 24% and 17% decrease in lactate and acetate production, correspondingly. Hence, the CRISPRi approach for H. thermocellum to downregulate metabolic genes can be used for remodelling of metabolic pathways without the requisite for genome engineering. These data established for the first time the feasibility of employing CRISPRi‐mediated gene repression of metabolic genes in H. thermocellum DSM 1313.
LeafByte: A mobile application that measures leaf area and herbivory quickly and accurately

Published: December 2019

Abstract

In both basic and applied studies, quantification of herbivory on foliage is a key metric in characterizing plant–herbivore interactions, which underpin many ecological, evolutionary and agricultural processes. Current methods of quantifying herbivory are slow or inaccurate. We present LeafByte, a free iOS application for measuring leaf area and herbivory. LeafByte can save data automatically, read and record barcodes, handle both light and dark coloured plant tissue, and be used non‐destructively.

We evaluate its accuracy and efficiency relative to existing herbivory assessment tools.

LeafByte has the same accuracy as ImageJ, the field standard, but is 50% faster. Other tools, such as BioLeaf and grid quantification, are quick and accurate, but limited in the information they can provide. Visual estimation is quickest, but it only provides a coarse measure of leaf damage and tends to overestimate herbivory.

LeafByte is a quick and accurate means of measuring leaf area and herbivory, making it a useful tool for research in fields such as ecology, entomology, agronomy and plant science.
Gender norms and intrahousehold allocation of labor in Mozambique: A CGE application to household and agricultural economics
Authors: Arora Diksha , Rada Codrina 
Published: December 2019

AbstractWe model intrahousehold dynamics in two rural provinces of Mozambique through the lens of computable general equilibrium (CGE) methods. The main features of our modeling framework are as follows: (a) a household social accounting matrix that captures allocation of labor and resources, and transfers among household members; (b) the explicit use of social norms in labor allocation across gender; (c) a mechanism that links agricultural production to time poverty; (d) identification of leisure as a commodity that is being produced. Simulation results and sensitivity analyses show how social norms interact with the allocation of labor and resources at the household level to impact farm production or limit the gains from technological improvements.
Physician and Pharmacist: Attitudes, Facilitators, and Barriers to Prescribing Naloxone for Home Rescue
Authors: Martino Janine G. , Smith Shawn R. , Rafie Sally , Rafie Samantha , Marienfeld Carla 
Published: December 2019

Background and ObjectivesWe implemented a naloxone education and distribution program in our academic health system. Despite the program, naloxone prescribing was not fully realized. This study aimed to identify the barriers to prescribing.MethodsWe conducted a prospective, cross‐sectional, mixed‐methods study of naloxone prescribers. Participants completed a questionnaire regarding their prescribing practices, attitudes, facilitators, and barriers to prescribing naloxone. Participants were then invited for an interview to further explore these topics and elicit more in‐depth explanations.ResultsSixty‐four physicians and eight pharmacists completed the questionnaire (n = 72). The most commonly reported barrier to prescribing naloxone was time constraints (33%). During the interviews, 14 subthemes emerged within four themes: provider competency, provider beliefs, health care system, and patient factors/social climate.DiscussionPrescribers identified barriers to naloxone prescribing despite implementation of an institutional overdose education and naloxone distribution (OEND) program. The results were similar to those previously reported prior to initiation of such programs.ConclusionIn this study, we examined barriers and facilitators to naloxone prescribing. Although previous studies have shown that health care providers endorsed similar barriers, our study indicates that some of those barriers persist despite a concerted effort to educate and promote prescribing via an OEND. While our study is limited by a small, selective sample size the results indicate that improvements to our OEND program are warranted.Scientific SignificanceOur study addressed an unexplored area of OEND research and may inform future program development.

Published: December 2019

ProblemThe application of primary eutopic endometrial cells from endometriosis patients in research is restricted for short life span, dedifferentiation of hormone responsiveness.Method of StudyHuman telomerase reverse transcriptase (hTERT)‐induced immortalized cells (iheESCs) were infected by lentivirus. mRNA level was examined by qRT‐PCR, and protein expression was quantified by Western blot. CCK‐8 and EdU assay were assigned to assess the proliferation. The migration and invasion of cells were assessed by transwell assay. Clone formation assay and nude mouse tumorigenicity assay were used to evaluate colony‐formation and tumorigenesis abilities.ResultshTERT mRNA and protein were significantly expressed higher in iheESCs compared to primary cells. iheESCs grew without morphological change for 42 passages which is much longer than 18 passages of primary cells. There was no obvious difference between primary cells and iheESCs in growth, mobility, and chromosome karyotype. Furthermore, the expression of epithelial‐mesenchymal transition (EMT) markers and estrogen/progesterone receptors remained unchanged. The decidualization of iheESCs could be induced by progesterone and cAMP. Estrogen increased the proliferation and mobility of iheESCs, and lipopolysaccharides (LPS) induced the IL‐1β and IL‐6 promoting inflammatory response. The colony‐forming ability of iheESCs, like primary cells, was lower than Ishikawa cells. In addition, tumorigenicity assay indicated that iheESCs were unable to trigger tumor formation in BALB/c nude mouse.ConclusionsThis study established and characterized iheESCs that kept the cellular physiology of primary cells and were not available with tumorigenic ability. Thus, iheESCs would be useful as in vitro cell model to investigate pathogenesis of endometriosis.

SummaryThe day 14 bone marrow aspirate and biopsy (D14BM) is regularly used to predict achievement of complete remission (CR) with induction chemotherapy in acute myeloid leukemia (AML), however its utility has been questioned. Clearance of peripheral blood blasts (PBB) may serve as an early measure of chemosensitivity. PBB rate of clearance (PBB‐RC) was calculated for treatment‐naive AML patients (n = 164) undergoing induction with an anthracycline and cytarabine (7+3) and with detectable PBB at diagnosis. PBB‐RC was defined as the percentage of the absolute PBB count on the day of diagnosis that was cleared with each day of therapy, on average, until D14 or day of PBB clearance. Each 5% increase in PBB‐RC approximately doubled the likelihood of D14BM clearance (OR = 1·81; 95% CI: 1·24–2·64,P < 0·005). PBB‐RC was also associated with improved CR rates (OR per 5% = 1·97; 95% CI: 1·27–3·01,P < 0·005) and overall survival (OS) [hazard ratio (HR) per 5% = 0·67; 95% CI: 0·52–0·87]. African American patients had poorer OS adjusted for PBB‐RC (HR = 2·18; 95% CI: 1·13–4·23), while race was not associated with D14BM or CR rate. PBB‐RC during induction chemotherapy is predictive of D14BM clearance, CR, and OS, and can therefore serve as a prognostic marker for clinical outcomes in AML.
