Transformational and entrepreneurial leadership: A review of distinction and overlap
Authors: Ravet-Brown Theo Émile , Furtner Marco , Kallmuenzer Andreas 
Published: March 2023

AbstractEntrepreneurship represents a key motor of economic growth, and entrepreneurial leadership (EL) represents a vital constituent thereof. However, its examination remains factious, and integration with the wider leadership literature is fragmentary. EL is claimed by some as representing a construct distinct from extant leadership styles, even though the major contribution made by transformational leadership (TL) theory remains under-researched and under-reported. Furthermore, TL is often used to measure leaders in entrepreneurship, resulting in a lack of clarity regarding the relationship between TL and EL. Our study seeks to contribute to the literature by elucidating the distinction and overlap between the two leadership constructs, as currently defined by available questionnaires. To this end, conceptual work, current findings, and research practice are reviewed. Drawn from a final sample of 25 articles, our findings show appreciable conceptual divergence. However, questionnaires of EL overlap significantly with TL and are subject to validation and discriminant validity issues; many researchers furthermore continue to use TL questionnaires to measure EL. Very little compelling empirical evidence for divergent validity was found, though strong correlations between EL and TL were observed. Our study contributes an overview of EL from the viewpoint of leadership science, providing recommendations to entrepreneurship researchers examining EL. We suggest that future work should satisfy two main goals: the establishment of a conceptualization of EL which can empirically demonstrate divergent validity versus other, accepted measures of leadership, and the creation of a cogent and a specific theoretical model to support it.

AbstractBreast cancer is one of the most common malignant tumors in women, and causes a large number of cancer-related deaths. The main cause of death of breast cancer patients is tumor recurrence and metastasis. Recent studies show that lncRNA (Long non-coding RNA) plays an important role in breast cancer. However, the overall biological activity and clinical consequences of the lncRNA MIR17HG in breast cancer remain unclear. Thus, we investigate how the MIR17HG/miR-454-3p network impacts breast cancer cell proliferation and migration. Given the TCGA and Oncomine databases, the researchers evaluated variations in MIR17HG expression for the survival rates of breast cancer patients. The influence of MIR17HG on cell proliferation, migration, cell cycle, and the mRNA expression level of miR-454-3p and FAM135A (family with sequence similarity 135 member A) is identified. Luciferase assay was used to detect the regulatory effect of miR-454-3p on the 3′UTR region of FAM135A, and rescue experiments demonstrated that MIR17HG can up-regulate FAM135A expression by competitively binding miR-454-3p. The effect of FAM135A on the cloning and invasion of MCF-7 cells was detected. MIR17HG expression is reduced in breast cancer tissues, and patients with greater levels of MIR17HG expression have a better prognosis. MIR17HG overexpression caused G2/M arrest in breast cancer cells according to a flow cytometry assay. FAM135A knockdown enhances breast cancer cell proliferation and clone creation, as well as two-dimensional and three-dimensional migratory capacities. Patients with high FAM135A expression in their breast cancer had a better prognosis. These novel findings indicate that MIR17HG may be a potential target for breast cancer. Our findings demonstrated that MIR17HG might suppress breast cancer cell proliferation and migration by sponge miR-454-3p through ceRNA(competing endogenous RNAs) mechanism, indicating that targeting MIR17HG may be a feasible therapeutic candidate for breast cancer.

Resilience to Shrinking as a Catch-Up Strategy: a Comparison of Brazil and Indonesia, 1964–2019
Authors: Axelsson Tobias , Martins Igor 
Published: March 2023

AbstractDevelopment economics has long focused on growth patterns to explain countries’ ability to catch up and forge ahead. We argue, however, that resilience to economic shrinking matters more. Using the examples of Brazil and Indonesia, we propose that a framework consisting of social capabilities—namely structural transformation, autonomy, and inclusion—can explain why Indonesia is more resilient to economic shrinking than Brazil and why the country is more likely to be successful in its catching-up process.
Daily arousal variation has little effect on sustained attention performance
Authors: Bond Isobel G. , Machida Keitaro , Johnson Katherine A. 
Published: March 2023

AbstractSustaining attention is an important cognitive process for everyday functioning and arousal is thought to underpin its performance. Primate studies depict an inverted-u relation between sustained attention and arousal, in which sustained attention performance is most affected at the extreme levels of arousal and peak performance aligns with moderate arousal. Human research findings are, however, inconsistent. This study aimed to investigate the effects of arousal on sustained attention performance in humans using two approaches—a small-N study with an inbuilt replication to test within-participant variation, and a larger sample assessing between-participant variation. The Sustained Attention to Response Task (SART) was used to measure sustained attention performance and the Karolinska Sleepiness Scale (KSS) was used to measure arousal. In the small-N study five participants completed the SART and KSS once an hour between 7 a.m. and 7 p.m., repeated two weeks later. Significant, curvilinear variation in KSS across time-of-day was found. A linear association between SART response time variability (sigma) and KSS was noted, however no other consistent associations between the SART and KSS were found. In the large-N study, 161 participants completed the SART and KSS once, at a time of day of their choosing. There were no significant relations between SART measures and the KSS, indicating that subjective sleepiness was not related to sustained attention performance. Overall, the hypothesized inverted-u relation between arousal and sustained attention performance was not found. The results suggested that diurnal arousal variation does not modify sustained attention performance in adults.

Published: March 2023

AbstractMicrowave photonic sensors are promising for improving sensing resolution and speed of optical sensors. In this paper, a high-sensitivity, high-resolution temperature sensor based on microwave photonic filter (MPF) is proposed and demonstrated. A micro-ring resonator (MRR) based on silicon-on-insulator is used as the sensing probe to convert the wavelength shift caused by temperature change to microwave frequency variation via the MPF system. By analyzing the frequency shift with high-speed and high-resolution monitors, the temperature change can be detected. The MRR is designed with multi-mode ridge waveguides to reduce propagation loss and achieves an ultra-high Q factor of 1.01 × 106. The proposed MPF has a single passband with a narrow bandwidth of 192 MHz. With clear peak-frequency shift, the sensitivity of the MPF-based temperature sensor is measured to be 10.22 GHz/°C. Due to higher sensitivity and ultra-narrow bandwidth of the MPF, the sensing resolution of the proposed temperature sensor is as high as 0.019 °C.

AbstractAngiogenesis occurred after myocardial infarction (MI) protects heart failure (HF). The aim of our study was to explore function of histone methyltransferase KMT2D (MLL4, mixed-lineage leukemia 4) in angiogenesis post-MI. Western blotting showed that KMT2D protein expression was elevated in MI mouse myocardial. Cardiomyocyte-specific Kmt2d-knockout (Kmt2d-cKO) mice were generated, and echocardiography and immunofluorescence staining detected significantly attenuated cardiac function and insufficient angiogenesis following MI in Kmt2d-cKO mice. Cross-talk assay suggested that Kmt2d-KO H9c2-derived conditioned medium attenuates EA.hy926 EC function. ELISA further identified that VEGF-A released from Kmt2d-KO H9c2 was significantly reduced. CUT&Tag and RT-qPCR revealed that KMT2D deficiency reduced Vegf-a mRNA expression and enrichment of H3K4me1 on the Vegf-a promoter. Moreover, KMT2D silencing in ECs also suppressed endothelial function. Our study indicates that KMT2D depletion in both cardiomyocytes and ECs attenuates angiogenesis and that loss of KMT2D exacerbates heart failure after MI in mice.

AbstractSince the first transplant in 1957 and hematopoietic stem cell transplantation (HSCT) is the curative modality for numerous hematological disorders. Nevertheless, it is not available for all patients. Besides unavailability of matched donors a lot of factors could hinder HSCT in a resource limited setting, as financial and administrative factors. In our daily practice we noticed other factors that hinder HSCT in our center, the common myths and misconceptions about HSCT and donation. This quasi-experimental study assessed, for the first time, common myths and misconceptions about HSCT among 218 medical and nursing students before and after an interventional educational program. The study tool was an investigators' developed self-administered questionnaire. Participants' male to female ratio was 1:2.5, and FAS was middle in 52.7%. Pretest high myths scores were reported in 53.4% and 90% of medical and nursing students that was reduced to 0% and 4% post-test, respectively. Pretest, 26.3% and 7% of medical and nursing students welling to donate HSC, that increased to 66% and 39% post-test, respectively. Rural residency, low and middle FAS associated with higher myths scores. Myths score is an independent effector of willingness to donate HSC among participants. In conclusion medical/nursing students had significant myths and misconceptions about HSCT that was corrected with the educational program. Thus, wide based educational programs about HSCT are mandatory to correct myths and augment HSC donation.www.clinicaltrrial.gov: clinical trial ID NCT05151406.

Abstract
Besides nitrate deposits located in the Atacama Desert of Chile and the Mojave Desert of California, the present work documents, for the first time, the occurrence of potassium nitrate as oval-suboval-shaped aggregations associated with the Late Maastrichtian-Early Paleocene Dakhla Shale and the Paleocene-Early Eocene Esna Shale encountered in the northeastern part of the Kharga Oasis, particularly at G. Um El-Ghanayem and G. Ghaneima. Consequently, integrated petrographic, mineralogical, and geochemical investigations were carried out for shale deposits and nitrate salts to reconstruct the paleoenvironmental conditions of shale, reveal the extent to which nitrate salts are genetically related to the paleoenvironment of shale deposits, and build up a complete scenario about the source and the formation mechanism of nitrate salts. The overall results showed that the studied shale deposits were sourced from mafic igneous and quartzose sedimentary provenances where humid climatic conditions were dominant; the transported detrital particles were then settled down under oxidizing bottom water and shallow depositional conditions. Moreover, the nitrate salts are of an epigenetic origin and sourced from the microbial nitrification of organic matter and the wet atmospheric deposition that is believed to be triggered by the active volcanic eruptions during the Late Eocene/Early Oligocene transition where warm climatic conditions prevailed.

Abstract
Amorphous silica, a specialised silicate adsorbent is extensively extracted from agricultural residues for application in various environmental domains. Wheat straws are a rich source of silica that have earlier been overlooked however demand for value addition. The study presents an innovative approach to extracting silica from wheat straw and standardising the extraction process to produce clean product. The sodium silicate solution and the amorphous silica synthesis were obtained by modifying the template mediated sol–gel method. Optimum temperature, concentration and pH were identified for the cleaner production of silica with maximum yield and favourable adsorbent characteristics. The crystallographic properties analysed by the X-Ray Diffraction revealed the amorphous nature of silica extracted from ash at 650 °C for 4 h. The structure of phytolith present in the wheat straw was observed in the form of articulated elongate undulate epidermal phytolith under scanning electron microscopy. The Energy Dispersive X-ray spectrum exhibited higher amount of silica (Si %) of 70.10% with a minimal percentage of potassium (9.96%). The sharp bend at 1025 cm−1 is attributed to the siloxane (Si–O-Si) vibrations in Fourier transform infrared spectroscopic graph of amorphous silica. The specific surface area measurements of amorphous silica showed type II isotherm curve with a hysteresis of H3 type. The optimum conditions derived to produce amorphous silica were 3 M NaOH and 3 M H2SO4 at pH 9.

AbstractDuring nursing education, few practical hours are devoted to comprehensively preparing students to care for a dying patient. Contact with a dying patient is a key element of the job of every working nurse in the profession. Therefore, it is necessary to properly prepare nurses to care for a dying patient. This study aimed to assess the professional competence of nurses in caring for a dying patient and the factors that affect this preparation. This study involved 223 nurses during master’s degree in nursing at the Medical University of Warsaw, receiving either full-time education (group I, N = 121) or hybrid education (group II, N = 102). The study used the FATCOD-BP ((Frommelt Attitudes Toward the Care Of the Dying scale Form B, Polish version)) questionnaire (Cronbach’s alpha 0.75), an original questionnaire containing questions about feelings experienced during the SARS-CoV-2 virus pandemic and sociodemographic questions. FATCOD-BP for all groups was below average regarding caring for a dying patient (M = 109, SD = 11.68). Nurses pursuing full-time education were better prepared to care for a dying patient than were nurses pursuing hybrid education. Nurses who exhibited fear of their own deaths had a lower subjective level of preparation for caring for a dying patient. (1) Nurses are not sufficiently prepared to care for a dying patient. (2) The training of nurses should be provided in the form of in-patient education, and the methods of training should be modified by increasing the number of hours of practical and theoretical instruction in palliative care for a dying patient.

AbstractQanat system, as a great human heritage, contributes to the sustainable management of groundwater in the arid and semiarid regions of the world. The main aim of this paper was to efficiency assessment of the environmental variables in the construction of the Qanat system in Iran. Using the geographical information system (GIS) and statistical method of receiver operation characteristic (ROC), the efficiency of 20 environmental variables was assessed based on divisions of 30 major hydrological basins. Results revealed that most physical parameters and anthropogenic characteristics have significant effects on the construction of Qanat water lines with an AUC index > 0.6. The Pearson correlation test also confirmed the positive and significant relationships between the Qanat system and mentioned environmental parameters. From a geological viewpoint, the results highlighted the effective role of Quaternary aged alluvial sediments with very high permeability and low density of crust rocks in arid soils of arid and semiarid regions, such as playa fields in NamakTehran, Kavir, Lut, and Siahkuh basins. Regarding the spatial expansion of the Qanat system in Iran, the higher effects of some test variables, such as the climatic element of temperature, fault density, and drainage density, were rejected due to poor discrimination values of the AUC index < 0.6.

AbstractReasonable volumetric fracturing effect evaluation is the key to effective stimulation of fractured reservoir. Traditional fracturing effect evaluation is mainly conducted by the SRV (stimulated reservoir volume), fracture length, fracture width and other indicators, ignoring the influence of failure mode on fracturing performance. In this paper, the different fracture modes including main fractures, branch fractures and self-supporting fractures contained in the fracture network and their contributions to fracturing effect were studied in depth by numerical simulation. The results show that the main fracture formed by tensile failure has the largest width but simple shape and relatively small distribution range, while the branch fracture has a slightly smaller width but effectively expands the main fracture. Although the self-supporting fracture by shear failure is not connected, it can still improve the overall flow conductivity. The angle and number of natural fractures in fractured reservoir have a significant effect on fracture network scale and fracturing effect. When the number of natural fractures is larger, both of the number and proportion of branching fractures and self-supported fractures are larger, although the isolated self-supported fractures account for a larger proportion, the overall flow conductivity of the final fracture network is stronger. When the angle of natural fractures is larger, the natural fractures in uniform stress field are easier to be connected by hydraulic fractures and the final fracturing effect is better. The research methods and results have a certain guiding significance for the evaluation of volumetric fracturing effect in fractured reservoirs and are conducive to the reasonable selection of favorable fracturing areas and engineering parameters.

Published: March 2023

AbstractA better understanding of the main forces that affect oil droplets is expected to play an important role in enhancing oil recovery from reservoirs. The effects of the various forces on an oil droplet on the top of a rock surface or hanging from the bottom of a rock surface are analysed. The results proved that increasing the mass of an oil droplet creates a favourable condition for interaction between the displaced and displacing fluids, which prevents the displacing fluid from bypassing the oil droplets. The results show that the mass of an oil droplet plays an important role in initiating its movement if the gravity force is greater than the capillary force. This study provides a sound understanding of the main forces affecting oil droplet movements and opportunities for future enhanced oil recovery projects.
Ecomodernism and the Libidinal Economy: Towards a Critical Conception of Technology in the Bio-Based Economy
Authors: Veraart Roel , Blok Vincent , Lemmens Pieter 
Published: March 2023

Abstract
In this paper, we carry out a critical analysis of the concept of technology in the current design of the bio-based economy (BBE). Looking at the current status of the BBE, we observe a dominant focus on technological innovation as the principal solution to climatic instability. We take a critical stance towards this “ecomodernist” worldview, addressing its fundamental assumptions, and offer an underarticulated explanation as to why a successful transition toward a sustainable BBE—i.e. one that fully operates within the Earth’s carrying capacity—has not yet been reached. Bernard Stiegler has developed a philosophical perspective on the concept of economy, broadening it to include the human condition through the notion of desire. This theory can help to obtain a more profound understanding of why ecomodernist strategies are dominant today. Stiegler’s theory of the libidinal economy offers an analysis of controlled and exploited human desire as a primary driver behind modern techno-economic structures. Our hypothesis is that a critique of contemporary technofixism as a critique of libidinal economy is a necessary step to take in the discussion around the BBE as a concept, if the BBE is ever to bring about a system that can truly operate within the Earth’s carrying capacity.
