Influencing decision-makers as the next step for entrepreneurship educators: lessons from entrepreneurship education in challenging economies

Based on research into the challenging and emerging economies of Peru and Egypt, this study explores how the potential role for entrepreneurship educators is evolving. Interviews and questionnaires with 70 participants from two strands of entrepreneurship, female entrepreneurship in Peru and social entrepreneurship in Egypt, are used to assess entrepreneurship in such challenging economies. Both regions, Latin America and Africa, need successes in entrepreneurship to help establish social, economic and political stability in their nation states. However, the relationship between entrepreneurship and national stability is complex and symbiotic, as national stabilities also help catalyse success in entrepreneurial and enterprise initiatives. The relevance of enterprise and entrepreneurial education and its impact on connected issues such as graduate attributes and employability is complex. This research indicates that, while entrepreneurship education is certainly an asset for individuals in terms of creating new ventures and in enhancing their employability, entrepreneurship educators should also focus on influencing the national decision-makers in challenging and emerging economies. This includes politicians, financiers and other leaders across the public, private and third-sectors of society, as it is often these individuals who create the necessary atmosphere and ethos for entrepreneurial initiatives to flourish

Multi-year total ozone column variability at three Norwegian sites and the influence of Northern Hemisphere Climatic indices

Total ozone column (TOC) measurements are retrieved from the Ozone Monitoring Instrument (OMI) onboard the NASA Earth Observing System (EOS) Aura satellite at the three Norwegian sites: Oslo (59.9 degrees N 10.7 degrees E, 1 m a.s. l.), Trondheim (63.4 degrees N 10.4 degrees E, 3 m a.s.l.) and Andoya (69.1 degrees N 15.7 degrees E, 32 m a.s.l.). TOC data have been analysed from 2005 to 2021, in order to detect annual and multi-years total ozone variability. The relationship between geopotential height (GPH) at 250 hPa and total ozone column has been evaluated after showing that monthly anomalies in GPH and TOC are correlated amongst the three sites. The influence of the three Northern Hemisphere Tele Connection (TC) indices (North Atlantic Oscillation, Arctic Oscillation and Scandinavia) on TOC variability has been investigated. It is found that Scandinavia index plays a prominent role for the northernmost latitudes of Andoya and Trondheim while North Atlantic Oscillation and Arctic Oscillation indices are weakly correlated (negatively) to TOC and (positively) to GPH at Oslo. The response of TOC variability to the solar activity at the three sites is also explored and it is noticed that in the period of increasing variation of solar activity, significant TOC anomaly events are only observed in Andoya and Trondheim

Identification and characterization of Vitis vinifera subsp sylvestris populations in north-western Italy

The Italian peninsula, for its favorable environmental and geo-morphological conditions, can be considered an ultimate area for survival and development of Vitis vinifera subsp. sylvestris (Gmelin) Hegi, even though severely affected by human impact. Large surveys started in early 1990 throughout the country. At the time few regions, like Piedmont located in the north-west of the country, were considered lacking of wild vinifera. More recent prospection started several years ago, leading to the discovering of five vinifera sylvestris populations plus other sites with few individuals. The sites of discovery were described for their ecological features and the identified plants were referenced and characterized by morphology (18 descriptors from the OIV list) and genetics (14 n-SSR loci). The esteemed consistency of each population ranged from 20 to 150 individuals. Morphological and biological traits (dioecious plants, females producing very small roundish black berries), as well as genetic profiles, indicated the observed plants are true vinifera sylvestris. As to the ecological requirements, plants were confirmed to be highly dependent on water availability into the soil. The neighbor-joining (NJ) dendrogram resulting from SSR allelic pattern of the individuals belonging to the five populations and to one location with isolated plants, indicated population's genetic similarity broadly reflects site's geographic distance. Considering the numerous reports in the past, spreading and consistency of wild grape germplasm from the region of Piedmont severely decreased over a period of 100-150 years. The relative short distance from wild population's sites and vineyards must also be regarded as a worrying condition because of contamination risks. All means to avoid the loss of this native Vitis germplasm must be undertaken by protection policy and proper land management

Ozone Improves the Aromatic Fingerprint of White Grapes

Ozone, a powerful oxidative stressor, has been recently used in wine industry as sanitizing agent to reduce spoilage microflora on grapes. In this study, we evaluated ozone-induced metabolic and molecular responses during postharvest grape dehydration. Ozone increased the contents of total volatile organic compounds (VOCs), which have a great impact on the organoleptic properties of grapes and wines. Among terpenes, responsible for floral and fruity aroma, linalool, geraniol and nerol were the major aromatic markers of Moscato bianco grapes. They were significantly affected by the long-term ozone treatment, increasing their concentration in the last phases of dehydration (>20% weight loss). At molecular level, our results demonstrated that both postharvest dehydration and ozone exposure induce the biosynthesis of monoterpenes via methylerythritol phosphate (MEP) pathway and of aldehydes from lipoxygenase-hydroperoxide lyase (LOX-HPL) pathway. Therefore, transcriptional changes occurred and promoted the over-production of many important volatile compounds for the quality of white grapes

Heart rate and arterial pressure changes during whole-body deep hypothermia

Whole-body deep hypothermia (DH) could be a new therapeutic strategy for asphyxiated newborn. This retrospective study describes how DH modified the heart rate and arterial blood pressure if compared to mild hypothermia (MH). Fourteen in DH and 17 in MH were cooled within the first six hours of life and for the following 72 hours. Hypothermia criteria were gestational age 6536 weeks; birth weight 651800\u2009g; clinical signs of moderate/severe hypoxic-ischemic encephalopathy. Rewarming was obtained in the following 6-12 hours (0.5\ub0C/h) after cooling. Heart rates were the same between the two groups; there was statistically significant difference at the beginning of hypothermia and during rewarming. Three babies in the DH group and 2 in the MH group showed HR 520\u2009ms. Infant submitted to deep hypothermia had not bradycardia or Qtc elongation before cooling and after rewarming. Blood pressure was significantly lower in DH compared to MH during the cooling, and peculiar was the hypotension during rewarming in DH group. Conclusion. The deeper hypothermia is a safe and feasible, only if it is performed by a well-trained team. DH should only be associated with a clinical trial and prospective randomized trials to validate its us

Second-order grey-scale texture analysis of pleural ultrasound images to differentiate acute respiratory distress syndrome and cardiogenic pulmonary edema

Discriminating acute respiratory distress syndrome (ARDS) from acute cardiogenic pulmonary edema (CPE) may be challenging in critically ill patients. Aim of this study was to investigate if gray-level co-occurrence matrix (GLCM) analysis of lung ultrasound (LUS) images can differentiate ARDS from CPE. The study population consisted of critically ill patients admitted to intensive care unit (ICU) with acute respiratory failure and submitted to LUS and extravascular lung water monitoring, and of a healthy control group (HCG). A digital analysis of pleural line and subpleural space, based on the GLCM with second order statistical texture analysis, was tested. We prospectively evaluated 47 subjects: 16 with a clinical diagnosis of CPE, 8 of ARDS, and 23 healthy subjects. By comparing ARDS and CPE patients’ subgroups with HCG, the one-way ANOVA models found a statistical significance in 9 out of 11 GLCM textural features. Post-hoc pairwise comparisons found statistical significance within each matrix feature for ARDS vs. CPE and CPE vs. HCG (P ≤ 0.001 for all). For ARDS vs. HCG a statistical significance occurred only in two matrix features (correlation: P = 0.005; homogeneity: P = 0.048). The quantitative method proposed has shown high diagnostic accuracy in differentiating normal lung from ARDS or CPE, and good diagnostic accuracy in differentiating CPE and ARDS. Gray-level co-occurrence matrix analysis of LUS images has the potential to aid pulmonary edemas differential diagnosis

Effects of a Cognitive-Motor Training on Anticipatory Brain Functions and Sport Performance in Semi-Elite Basketball Players

The aim of this research was to test the possible effects of cognitive–motor training (CMT) on athletes’ sport performance and cognitive functions. Namely, specific athletic tests, brain processes associated with anticipatory event-related potential (ERP) components and behavioral performance during a cognitive discrimination response task were evaluated pre-and post-training. Twenty-four young semi-professional basketball players were recruited for the study and randomly divided into an experimental (Exp) group executing the CMT training and a control (Con) group performing standard motor training. The CMT training protocol included exercises in which participants performed cognitive tasks during dribbling exercises using interactive devices which emitted visual and auditory stimuli, in which athletes’ responses were recorded. Results showed that following training, only the Exp group improved in all sport-specific tests (17%) and more than the Con group (88% vs. 60%) in response accuracy during the cognitive test. At brain level, posttraining anticipatory cognitive processes associated with proactive inhibition and top-down attention in the prefrontal cortex were earlier and heightened in the Exp group. Our findings confirm previous studies on clear improved efficacy of CMT training protocols on sport performance and cognition compared to training based on motor exercises only, but extend the literature in showing that these effects might be explained by enhanced anticipatory brain processing in the prefrontal cortex. The present study also suggests that in order to achieve specific athletic goals, the brain adapts cognitive functions by means of neuroplasticity processes
