Environmental and Financial Performance. Is there a win-win or a win-loss situation? Evidence from the Greek manufacturing

This study examines the causal linkage between environmental and financial performance in Greek manufacturing firms. Environmental performance is measured according to accounting data following the Eco Management and Auditing Scheme guidelines and ISO certification. Return on assets and return on sales are used as indicators of financial performance. Empirical findings suggest that there seems to be a link between these dimensions irrespectively of the particular sector of activity. Contrary to similar studies a “virtuous circle” does not exist as the avoidance of environmental improving investments is related to a better financial performance. On the other hand firms with superior financial performance seem to achieve a better environmental performance. At the same time firm specific and market characteristics significantly affect this relationship. These findings provide evidence that governmental and corporate actions are necessary in order to lead to a more sustainable corporate performance in the long ru

Pneumatized superior turbinate as a cause of headache

BACKGROUND: A pneumatized superior turbinate is a rare cause of headache. Nasal endoscopy alone, does not provide us with adequate information for this inaccessible area of the superior nasal cavity. A coronal computed tomography (CT) must be obtained to confirm the diagnosis. CASE PRESENTATION: We present a 40-year-old female with migraine-type headache and nasal obstruction. Nasal endoscopy revealed a mild septal deviation, a right middle concha bullosa and a paradoxically curved middle turbinate on the left side. Coronal CT-scan showed also the presence of a superior concha bullosa on the left, which was in close contact with the nasal septum. The patient underwent septoplasty and bilateral endoscopic sinus surgery, including partial removal of both the pneumatized middle turbinates in conjunction with gentle lateralization and resection of the lower half of the left superior turbinate. Prompt relief from headache and nasal symptoms was obtained. CONCLUSION: Pneumatized superior concha causing migrainous headache is a rare finding. Endoscopic surgery may provide permanent relief of symptoms

Socratic dialogue as a teaching and research method for co-creativity?

We sketch a theory of creativity which centres on the framing of activity by repetitive thinking and action, and sees creativity as divergences from these routines which is thereby framed against them. Without a repetitive frame creativity is impossible. Mere repetition is not creative, even if new. Creativity disrupts a frame, purposefully. Socratic Dialogue is an ancient technique of engaging a student in a dialogue by asking non-leading questions, aimed at revealing to the student how much knowledge he or she already has on some topic: Socrates’ demonstration to the slave-boy (and the audience) that the boy already knows geometry (without any schooling) is the founding example. We aim to illustrate that internalising the Socratic kind of reflective self-questioning and co-questioning is intimately related to the view of creativity as the reframing of routine. Therefore, we have qualitatively analysed primary and secondary school pilots in Greece, Austria and the United Kingdom. The illustrations of facilitated Socratic Dialogues with children and young people have been derived from the analysis of 14 Socratic Dialogues involving a total number of 97 students. This paper outlines the Socratic Dialogue as a method of both researching and teaching creative thinking, and it reveals that the Socratic method dovetails with this conception of co-creativity. As a research method, Socratic Dialogue aims to elicit information concerning reasoning processes and shared experiences. As a teaching method, Socratic Dialogue aims to get students to internalise the public methodology of Socratic Dialogue, and to adopt it across the range of domains they meet. The students’ use of the internalised method towards enabling creative thinking is illustrated by the experiences of the teaching intervention teams in the C2Learn project, using games to provide occasions for co-creativity

Etiology of Anemia in Patients With Advanced Heart Failure

ObjectivesWe prospectively investigated the causes of anemia in patients with advanced congestive heart failure (CHF).BackgroundAnemia is common in patients with advanced CHF, and its etiology is generally considered to be multifactorial. However, despite its importance, precise information is lacking regarding the prevalence of putative etiologic factors.MethodsPatients who were hospitalized for decompensated advanced CHF and who were stabilized after their initial treatment underwent evaluation of “clinically significant” anemia, defined as a hemoglobin content <12 g/dl for men and <11.5 g/dl for women. Patients with a serum creatinine concentration >3 mg/dl or patients with concurrent diseases that are known to cause anemia were not included. The initial evaluation included measurements of vitamin B12, folic acid, thyroid-stimulating hormone, erythropoietin, lactate dehydrogenase, Coombs test, multiple fecal occult tests, and bone marrow aspiration. Patients without diagnosis by these methods underwent red cell mass measurement with 51Cr assay.ResultsThe mean age of the 37 patients was 57.9 ± 10.9 years and mean left ventricular ejection fraction 22.5 ± 5.9%. Iron deficiency anemia was confirmed by bone marrow aspiration in 27 patients (73%), 2 patients (5.4%) had dilutional anemia, and 1 patient (2.7%) had drug-induced anemia. No specific cause was identified in 7 patients (18.9%) who were considered to have “anemia of chronic disease.” Serum ferritin for the iron-deficient patients was not a reliable marker of iron deficiency in this population.ConclusionsIn this group of patients, iron deficiency was the most common cause of anemia. The iron status of patients with end-stage chronic CHF should be thoroughly evaluated and corrected before considering other therapeutic interventions

Enhancing the Air Stability of Dimolybdenum Paddlewheel Complexes : Redox Tuning through Fluorine Substituents

The optical and electrochemical properties of quadruply bonded dimolybdenum paddlewheel complexes (Mo2PWCs) make them ideal candidates for incorporation into functional materials or devices, but one of the greatest bottlenecks for this is their poor stability toward atmospheric oxygen. By tuning the potential at which the Mo2 core is oxidized, it was possible to increase the tolerance of Mo2PWCs to air. A series of homoleptic Mo2PWCs bearing fluorinated formamidinate ligands have been synthesized and their electrochemical properties studied. The oxidation potential of the complexes was tuned in a predictable fashion by controlling the positions of the fluorine substituents on the ligands, as guided by a Hammett relationship. Studies into the air stability of the resulting complexes by multinuclear NMR spectroscopy show an increased tolerance to atmospheric oxygen with increasingly electron-withdrawing ligands. The heteroleptic complex Mo2(DFArF)3(OAc) [where DFArF = 3,5-(difluorophenyl)formamidinate] shows remarkable tolerance to oxygen in the solid state and in chloroform solutions. Through the employment of easily accessible ligands, the stability of the Mo2 core toward oxygen has been enhanced, thereby making Mo2PWCs with electron-withdrawing ligands more attractive candidates for the development of functional materials

Production of Y(1S) Mesons from chib Decays in pp(bar) Collisions at sqrt(s)=1.8 TeV

We have reconstructed the radiative decays $\chi_{b}(1P) \to \Upsilon(1S) \gamma$ and $\chi_{b}(2P) \to \Upsilon(1S) \gamma$ in $p \bar{p}$ collisions at $\sqrt{s} = 1.8$ TeV, and measured the fraction of $\Upsilon(1S)$ mesons that originate from these decays. For $\Upsilon(1S)$ mesons with $p^{\Upsilon}_{T}>8.0$ GeV/$c$, the fractions that come from $\chi_{b}(1P)$ and $\chi_{b}(2P)$ decays are $(27.1\pm6.9(stat)\pm4.4(sys))$ and $(10.5\pm4.4(stat)\pm1.4(sys))$, respectively. We have derived the fraction of directly produced $\Upsilon(1S)$ mesons to be $(50.9\pm8.2(stat)\pm9.0(sys))$.Comment: 13 Pages, 2 figure

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
