Neoliberalism, leadership, and democracy: Schumpeter on “Schumpeterian” theories of entrepreneurship

This article reinterprets Schumpeter’s theory of entrepreneurship in a decidedly un-“Schumpeterian” way, and argues that continued emphasis on Schumpeter’s alleged glorification of the entrepreneur constitutes a missed opportunity for democratic critics of capitalism and neoliberalism. I demonstrate that Schumpeter did not exalt the individual entrepreneur as the paradigm for economic and political leadership in capitalist societies, and I show that he offers a surprisingly robust resource for reconceptualizing entrepreneurship. Schumpeter theorized entrepreneurship: (1) as a phenomenon that could not be exemplified by either individual persons or strictly private entities; (2) as a conceptual mechanism for analyzing change in the history of capitalism; and (3) even as evidence that political and economic leadership should not be conflated in modern democratic societies. By contextualizing Schumpeter’s discussions of the entrepreneur, I suggest that a reconsideration of Schumpeter’s actual theory of entrepreneurship would invigorate contemporary debates about the role of leadership in capitalist economies and liberal-democratic polities.
On the density of ℚ in ℝ: Imaginary dialogues scripted by undergraduate students

This study aims to explore the notion of the density of the set of rational numbers in the set of real numbers, as interpreted by undergraduate mathematics students. The data comprise 95 responses to a scripting task, in which participants were asked to extend a hypothetical dialog between two student characters, who argue about the existence of one or infinitely many rational numbers in a real number interval. The analysis leans on the framework of reducing abstraction to provide explanations for the participants’ mathematical behaviour when coping with the task. The findings point to students’ informal ideas related to density that can be mapped to formal proofs, as well as to unconventional understandings of related concepts and ideas, including rational and irrational numbers, infinity, and mathematical justification. Implications are drawn.
A single pleiotropic locus influences the rate of hybridization between two sibling species of Lygaeus bugs

Abstract The evolution of reproductive isolation lies at the heart of understanding the process of speciation. Of particular interest is the relationship between pre‐ and postzygotic reproductive isolation, and the genetic architecture of traits that contribute to one or both forms of reproductive isolation. The sibling species of seed bug Lygaeus equestris and L. simulans show a classic pattern of asymmetric prezygotic reproductive isolation, with female L. equestris hybridizing with male L. simulans, but with no hybridization in the reciprocal direction. We have recently described a mutant pale color form of L. simulans, that inherits as a single Mendelian locus and is pleiotropic for a number of other life history and behavioral traits. Here, we tested whether this locus also influences pre‐ and postzygotic reproductive isolation. Two sets of experimental crosses revealed that behavioral isolation varied with mutant versus wild‐type phenotype for male L. simulans, with the pale form less successful at mating with female L. equestris. In terms of trying to assess postzygotic isolation, levels of hybrid offspring production were uniformly low across the experiments. However, we did obtain, for the first time, hybrid offspring from a pairing between a female L. simulans and a male L. equestris. In this instance, the female was of the pale mutant genotype. Together with evidence for heterozygote advantage in terms of nymph survival, we consider our results in terms of possible mechanisms of reproductive isolation between this species pair, the role of the pale mutation, and the possible genetic architectures underlying the mutation, from a single gene to a supergene.
Effects of Perceived Professional Learning and Supportive Work Environment on Job Satisfaction and Transfer of Training

In all those functions which require cognitive thought process, trainability is recently recognized as a major problem for managers. Despite considerable amount of investment in training and development, managers often remain unsuccessful to transfer the training contents to others in their organizations. This paper analyzes a) the impact of perceived professional learning, supervisor support, and peer support on job satisfaction and in turn, on the transfer of training; and b) whether job satisfaction mediates the relationship between three variables (perceived professional learning, supervisor support, and peer support), and transfer of training. A useable sample of 384 managers is drawn from five private hospitals of Karachi, Pakistan. A measurement model is constructed with high validity and reliability, whereas hypotheses are tested using a covariance-based structural equation modeling (CB-SEM) method. We used SPSS, AMOS and Jamovi® software applications for data analysis. The results show that perceived professional learning and peer support have a significant and positive effect on job satisfaction and in turn, on the transfer of training. Similarly, job satisfaction mediates the relationship between the two variables (perceived professional learning and peer support), and transfer of training. Nevertheless, contrary to our hypotheses, supervisor support does not have a significant effect on job satisfaction, and job satisfaction does not mediate the relationship between supervisor support and transfer of training too. This study contributes to the training literature in three different ways. First, it extends the findings of Western studies to the private healthcare institutions of Pakistan. Second, it is perhaps the first report to reveal job satisfaction as a significant new predictor of transfer of training. Third, job satisfaction also mediates the positive relationship between perceived professional learning and transfer of training as well as between peer support and transfer of training. Theoretical contributions, managerial implications, limitations, and directions for future studies are discussed.
Total and Sustainable Valorisation of Olive Pomace Using a Fractionation Approach

Olive pomace management represents a great concern to the olive oil industry. This work focused on the development of a “zero waste” strategy for olive pomace based on a fractionation approach resulting in the obtention of different value-added fractions. The physicochemical composition of edible fractions obtained (liquid and pulp) was analysed. The potential use as a solid biofuel of the non-edible fraction (stones) was evaluated. High amounts of hydroxytyrosol (513.61–625.76 mg/100 g dry weight) were present in the liquid fraction. Pulp fraction was demonstrated to be a good source of fibre (53–59% dry weight) with considerable antioxidant activity both from free and bound phenolics. The stones fraction exhibited substantial high heating values (18.65–18.94 megajoule (MJ/kg). All these results support the added value of the olive pomace fractions combining the biofuel potential from the stones fraction and the functional food ingredients’ potential both from liquid and pulp fractions. The present methodology seems to be a feasible whole valorisation approach to achieve the circularity in the olive oil sector, prioritising obtaining high over low added-value products.
In vitro antibacterial activity of Psidium guajava (Guava) leaves extract on carbapenem-resistant Klebsiella pneumoniae causing multi-drug resistant systemic infections

Systemic bacterial infections affect almost all part of the human body systems leading to infections such as urinary tract infections, septicemia, meningitis, pneumonia, peritonitis and gastritis. Carbapenems have been used as drug of choice in the treatment of systemic infections. Studies have indicated that Enterobacteriaceae are producing enzymes such as carbapenemases, which inactivate carbapenems. There is limited treatment option for systemic infections caused by carbapenem- resistant Enterobacteriaceae. Systemic infections keep increasing; hence, the determination of the effective treatment options of carbapenem-resistant Enterobacteriaceae is important for quality healthcare delivery. In this laboratory studies, agar well diffusion and well microplate dilution of the ethanolic extract of the guava leaves was used to determine the effectiveness of Psidium guajava on carbapenem-resistant K. pneumoniae. The antimicrobial compounds responsible for the antibacterial activity were screened using standard methods. The active zones of inhibition were observed in P. guajava leaves extract concentrations of 50, 100 and 200 mg/ml. The minimum inhibition concentration and minimum bactericidal concentration of ethanolic extract of guava leaves was 6.25 mg/ml indicating significant antibacterial activity against the carbapenem-resistant K. pneumoniae. The antibacterial activity of the leaves extract may be attributed to the presence of flavonoids and other antimicrobial phytochemicals in the guava leaves extract. The outcome of this baseline laboratory studies indicates the possibility of producing efficacious antibiotic to treat carbapenems-resistant systemic infections. The determination of the toxicological effect of the isolated active antimicrobial compounds of guava leaves extract is worth following in subsequent studies. Key words: Psidium guajava, phytochemicals, Carbapenem, Carbapenem-resistant Klebsiella pneumonia.
Exposing Zebrafish to Silver Nanoparticles during Caudal Fin Regeneration Disrupts Caudal Fin Growth and p53 Signaling

Zebrafish were exposed to commercial silver nanoparticles (10-20 nm) at 0.4 and 4 ppm during cadual fin regeneration. The silver was in the ionic form. Fin regeneration was slow in the group exposed to the lower concentration. The cadual fin, gill, and muscle were assayed after 48 hours and subjected to histological analysis. In all tissues sampled, fish exposed to nanoparticles exhibited infiltration, large mitochondria with empty matrices, and accumulation of nano-sized silver in blood vessels. The results suggested mitochondrial damage and induction of inflammation. Microarray analysis of RNA from young zebrafish (52 hours post-fertilization) that were exposed to nanometer-sized silver particles, showed alteration in expression of the p53 gene pathway related to apoptosis. Gene expression changes in the nanoparticle-treated zebrafish led to phenotypic changes, reflecting increased apoptosis.
Influence of parent age and some plant extracts on certain biological aspects of pulse beetle, Callosobruchus chinensis L. (Coleoptera: Bruchidae)

The present work was carried out to study the effect of age of parents and some plant extracts against pulse beetle, Callosobruchus chinensis L. on chickpea seeds. The results generally showed that, fecundity of C. chinensis increased in the females with younger ages and reduced in those with progress age females, while the time of development increased significantly with the increase in age of parents of either sexes. Also, leaves of castor (Ricinus communis L.), datura (Datura stramonium L.), Jatropha (Jatropha curcas L.) and neem (Azadirachta indica A. Juss) were used in acetone and aqueous extracts. The results indicated that among all the tested plant extracts, neem leaf extract was significantly affect oviposition deterrent, reduction of the adult emergence of C. chinensis and antifeedant as compared to other extracts. In general, acetone extract of leaf of the tested plants were more effective than those of aqueous extract.
Erratum: Numerical simulation of Li-pellet injection experiments for ELM-pacing in EAST (2020 Nucl. Fusion 60 066022)

The injection of light impurity granules into fusion research discharges has shown a great potential for ELM pacing in future nuclear devices. The present work employed a model considering both pellet ablation and transport to systematically study for the first time the evolution of both impurity Li species and target plasma in the edge plasma during single and repeated Li pellet injections, with all initial information extracted from the EAST experiments. The evolutionary distributions of atomic and ionized Li species were presented and show good consistency with experimental CCD camera images. Simulation studies were carried out for single and repeated pellet injections at the outer mid-plane, and statistical uncertainty of ELM pacing rates triggering ELMs is discussed with regard to related injection conditions. It is found that the pressure locally caused by an ELM pacing pellet (with a diameter of 0.6 ~ 0.7 mm) was 1.8–2.4 times its unperturbed magnitude in the EAST shots of interest. Accumulation from repeated pellet injections results in the rise of pedestal height at a high injection frequency and this effect becomes stronger with increasing pellet size. Pressure changes are also evident in a scenario of multiple small pellets per stroke, which could lead to a nonnegligible, probabilistic ELM triggering rate observed experimentally. The effects of other possible factors are also discussed. With the assumption that the ELM trigger rate of a Li pellet of 0.7 mm diameter is 100%, the predicted trigger rates are in good agreement with those observed in experiments. This work can help understand the statistically probabilistic behavior of ELM triggering efficiency observed in previous studies.
A genre-based study of professional reflective writing in higher education

ABSTRACT There is a growing expectation internationally that teachers in higher education obtain professional recognition through accredited schemes which confer Fellowship status. Such schemes often require a written reflective submission to demonstrate effective teaching and professional experience. Yet despite this burgeoning interest, little is known about the generic features of professional reflective writing, and in particular, the ‘case study’ as part of a fellowship submission. Through a genre analysis of a corpus of case studies taken from successful texts we illuminate the rhetorical and linguistic features of the case study to inform writing support for teachers in higher education. We suggest how a genre pedagogy approach can both provide scaffolding to teachers engaging in professional reflective writing and empower teachers to manage new writing discourses by developing the tools of genre analysis.
Molecular Phylogeny of Yeasts from Palm Wine and Enological Potentials of the Drink

Palm wine is consumed around the world and known by various names. Unlike many good quality traditional fermented food and drink in developing countries that have only been marketed in their local communities, palm wine has proved to be a commercial success in that it is now canned or bottled and marketed internationally. Despite these advances, the drink has not been subjected to current technology applied to wines from grapes to improve quality. This review highlights the evolutionary relationships between yeasts isolated from the drink in two continents and the enological potential of the drink. The evolutionary history was inferred by using the Molecular Evolutionary Genetics Analysis (version 7) computer software to construct phylogenetic trees using 34 previously reported curated nucleotide sequences from the D1/D2 domain of 26S rRNA in yeasts isolated from the drink. We found that similar yeast species formed terminal taxa from a common node. However Pichia kudriavzevii species formed two distinct clades which suggest intra-species diversity. One Saccharomyces cerevisiae (accession No. HG425326) had a node distinct from other Mini-review Article Nwaiwu and Itumoh; ARRB, 20(3): 1-12, 2017; Article no.ARRB. 37748 2 S. cerevisiae species indicating that the strain may belong to a different lineage. From literature, the enological compounds measured in different types of wines like ethyl acetate, oleic acid, ethanol, and acetic acid are present in palm wine. These primary and secondary metabolites of palm wine from different yeasts confirm the enological potentials of the drink even though higher alcohols and esters appear to be more in some wines when compared to palm wine. Future research may involve more holistic investigations that will elucidate the biochemical pathway of palm wine fermentation products.
How emotional memory affects face remembering: an ERP investigation

It is known that the longer an information has been memorized, the stronger is its memory trace. At the same time it is known that the emotionally-valenced information has a stronger memory trace than neutral one. Interactive effects between these factors are largely unknown. In this study electrical neuroimaging signals were recorded in healthy controls to explore the neural mechanism of memory for faces of different emotional valence, sex, learning context and temporal recency. In a study phase participants familiarized with the fictional police dossier of 10 victims of dramatic deaths including homicide or earthquake (depicted as attractive and nice persons of about 45 years), twice a day for seven days before EEG recordings. Hundreds of famous movie stars (overlearned), victims (recent) and new faces were presented in an old/new recognition task. ERP responses showed a modulation of anterior N2 and FN400 as a function of face familiarity (with no differences between overlearned and recent faces), while parietal late positivity was sensitive to engram temporal recency (it was much larger to overlearned than recent faces, paralleling behavioral data). However, LP amplitude did not differ to overlearned vs. recent same-sex faces, showing how emotional memory can enhance faces remembering. A late frontal negativity revealed sensitive to source memory.
Clostridium perfringens and its potential role in equine colitis

CLOSTRIDIUM PERFRINGENS AND ITS POTENTIAL ROLE IN EQUINE COLIT Iman Mehdizadeh Gohari Co-advisors: University of Guelph, 2012 Dr. J. F. Prescott Dr. L. Arroyo Although progress has been made in the last decade in understanding the causes of colitis in horses, perhaps 60% of cases of fatal colitis in horses have no known cause. The role of type A Clostridium perfringens strains was evaluated in this study. Fecal samples from 55 horses (43 adults, 12 foals) with colitis were cultured for Clostridium difficile, Salmonella, and C. perfringens. Feces were also tested for C. difficile toxins A/B and C. perfringens toxins (alpha [CPA], beta2 [CPB2], enterotoxin [CPE]) using enzyme-linked immunosorbent assays (EIA). All fecal samples were negative for Salmonella. Clostridium perfringens and C. difficile were isolated from 40% and 5.4% of samples, respectively. No CPE was detected but 36.4% and 18.2% of animals were positive for CPA and CPB2 toxin, respectively. Subsequently, five C. perfringens isolates per fecal sample were genotyped and the supernatants of each of these isolates were evaluated for toxicity. None of the isolates were cpe, netB or tpeL positive, but atypical cpb2 and consensus cpb2 were identified in 13.6% and 3.6% isolates, respectively. All equine C. perfringens isolates showed mild toxicity effects compared to CPB producing C. perfringens positive control. Based on this study population, there was no evidence that C. perfringens had an important role in equine colitis.

The study aimed to isolation and identification of Enterobacter spp. from different clinical infections ,as well as virulence factors encoding gene were detected by PCR.The clinical specimens (100) were collected from patients suffering from different infectious from various hospitals of Najaf during the period from February 2011 to June 2012. Enterobacter isolates which were diagnosed according cultural and biochemical tests as well as API 20E . Eighty four isolates of Enterobacter were collected, from different samples which distributed in two species of Enterobacter , E.cloacae (89.3%) and E.sakazakii (10.7 %) . The results showed that all isolates were produced of siderophore , and most isolates were capsule formation , but give negative result for haemolysin and protease . Also, 80 (95%) of Enterobacter has the CFA / III and 15(18 %) of isolates are bacteriocin production. The results showed that 26 (31%) of isolates were had rpo S gene , and these isolates were more resistance to stress conditions which lack the gene . The resistance was high in stationary phase than that in log phase. The result showed that all isolates were contained nitroreductase gene, but not had shiga like toxin gene.
Germination and seedling growth of barley as affected by Artemisia annua water extract

Laboratory and greenhouse pot experiments were conducted to assess the allelopathic effects of Artemisia annua water extract on germination and growth of barley. Lower concentrations of A. annua water extract (0.5 and 1.0 %) did not affect the germination of barley seeds. However, higher concentrations (1.5-3.5 %) resulted in significant reductions in the germination percentage. Seedling growth of barley was also affected by A. annua water extract. Both shoot and root lengths were negatively affected by A. annua water extract and the degree of inhibition was concentration dependent. When barley seedlings were subjected to 0.5% extract concentration, shoot length was inhibited by 6% while root length showed 18.5% inhibition over control seedlings. The lowest shoot and root lengths were recorded at 3.0 and 3.5 % water extract. At 0.5 % extract concentration, shoot and root fresh and dry weights were significantly unaffected compared with the control. Shoot fresh weight was significantly unaltered when seedlings were treated with 1.0 % extract. However, at the same concentration root fresh weight, shoot dry weight, and root dry weight were inhibited by 44.7, 33.3, and 40 %, respectively. The present results confirmed that root growth (length and weight) was more sensitive to A. annua water extract than shoot growth. The present results also indicated the presence of water soluble allelochemicals in A. annua that are able to inhibit growth of barley.
