The Socialization of STEM Professionals Into STEM Careers: A Study of Newly Hired Engineers
Authors: Korte Russell , Brunhaver Samantha , Zehr Sarah M. 
Published: December 2018

The Problem Recently there has been a growing interest to increase the number of people entering science, technology, engineering, and mathematics (STEM) careers. One of the major problems with this “supply-side” model is that it sees STEM workforce development narrowly as one of inputs (recruitment) and ignores the practice of STEM work, which affects the retention of professionals in STEM careers. The Solution Informed by recent research and theory on career development, we studied the work experiences of newly hired engineers in one organization. A key finding is that a major part of their experiences involved organizational work and social dynamics outside of what many considered to be “real” engineering work. We propose that these experiences provide important insights for the education and retention of STEM workers. The Stakeholders Faculty in higher education that prepare STEM workers, managers in organizations that hire new STEM workers, and aspiring STEM workers.

Purpose We aimed to analyse the patency rate of the anterior choroidal artery, and presented imaging and neurological findings, after deployment of a flow diverter in the anterior choroidal artery in the treatment of patients with intracranial aneurysms. Methods Among the 139 patients who underwent a flow diverter deployment from December 2012 to September 2017 in our hospital, there were 21 patients (15.1%) for whom their anterior choroidal artery was covered for the procedure with a flow diverter. The patients' age, sex, size of aneurysm and the presence or absence of an anterior choroidal artery occlusion, neurological findings and postoperative infarction in the anterior choroidal artery region were analysed retrospectively. Results The mean age of the six male and 15 female patients was 61.5 years (range 32–77 years). The mean maximal diameter of the aneurysms was 16.4 mm (range 10.0–29.4 mm). The anterior choroidal artery was patent in all 21 patients; however, a haemodynamic alteration in the anterior choroidal artery was detected in one patient. Postoperatively, hemiparesis was observed in two patients (9.5%) and a visual field defect in one patient (4.8%), both of which were the symptoms of infarction of the cortical branch of the middle cerebral artery or retinal artery ischaemia. However, no patients had symptoms due to ischaemia of the anterior choroidal artery confirmed with magnetic resonance imaging. Conclusions In all patients who underwent flow diverter deployment, the anterior choroidal artery was patent and no ischaemia was detected in the imaging or evidenced by neurological findings. Therefore, flow diverter deployment in the anterior choroidal artery was considered to be a safe procedure.

Published: December 2018

Introduction: An integrated health and social care program for patients with heart failure (HF) was implemented at the Friuli-Venezia Giulia deployment site as part of the SmartCare European project. The objective of this study was to validate 2 different decision modeling techniques used to perform the economic evaluation. Methods: Data were collected during the SmartCare project which enrolled 108 patients with HF and followed for more than 6 months. The techniques used were Markov and discrete event simulation models. In both cases, a cost-effectiveness analysis and a budget impact analysis were carried out. The former was used to assign priority to the intervention and the latter to assess its sustainability. Analyses were conducted from the perspective of the Regional Health Authority. Results: Results were similar with both types of model. Cost-effectiveness analysis found no significant differences in quality of life, but the intervention generated significant cost savings, becoming the dominant option. Data extrapolation showed no benefits in terms of mortality or hospital admissions, but budget impact analysis also predicted annual savings, as a significant number of in-hospital days were avoided. In budget analysis, both models predicted early, increasing and cumulative annual savings. Discussion: The integrated program was dominant as it provided better outcomes and lower total costs, and thus, decision-makers should prioritize it. Besides, the work demonstrates the capacity of decision modeling to become a complementary tool in managing integrated health and social care models.

Abstract
Ravulizumab (ALXN1210), a new complement C5 inhibitor, provides immediate, complete, and sustained C5 inhibition. This phase 3, open-label study assessed the noninferiority of ravulizumab to eculizumab in complement inhibitor–naive adults with paroxysmal nocturnal hemoglobinuria (PNH). Patients with lactate dehydrogenase (LDH) ≥1.5 times the upper limit of normal and at least 1 PNH symptom were randomized 1:1 to receive ravulizumab or eculizumab for 183 days (N = 246). Coprimary efficacy end points were proportion of patients remaining transfusion-free and LDH normalization. Secondary end points were percent change from baseline in LDH, change from baseline in Functional Assessment of Chronic Illness Therapy (FACIT)–Fatigue score, proportion of patients with breakthrough hemolysis, stabilized hemoglobin, and change in serum free C5. Ravulizumab was noninferior to eculizumab for both coprimary and all key secondary end points (Pinf &lt; .0001): transfusion avoidance (73.6% vs 66.1%; difference of 6.8% [95% confidence interval (CI), −4.66, 18.14]), LDH normalization (53.6% vs 49.4%; odds ratio, 1.19 [0.80, 1.77]), percent reduction in LDH (−76.8% vs −76.0%; difference [95% CI], −0.83% [−5.21, 3.56]), change in FACIT-Fatigue score (7.07 vs 6.40; difference [95% CI], 0.67 [−1.21, 2.55]), breakthrough hemolysis (4.0% vs 10.7%; difference [95% CI], −6.7% [−14.21, 0.18]), and stabilized hemoglobin (68.0% vs 64.5%; difference [95% CI], 2.9 [−8.80, 14.64]). The safety and tolerability of ravulizumab and eculizumab were similar; no meningococcal infections occurred. In conclusion, ravulizumab given every 8 weeks achieved noninferiority compared with eculizumab given every 2 weeks for all efficacy end points, with a similar safety profile. This trial was registered at www.clinicaltrials.gov as #NCT02946463.
Infidel America: Puritan Legacy and Antebellum Religious Persecution in Frederick Douglass’s Transatlantic Speeches, 1841–49
Authors: Grace Daniel 
Published: November 2018

Abstract
This essay examines Frederick Douglass’s oratory of the 1840s, when religious appeals drove his abolitionist rhetoric. In addressing the lack of critical attention paid to his early oratory and evangelism, the essay argues that these speeches, which he delivered to audiences in the US North and Europe, offer an incisive transatlantic critique of the religious roots of American exceptionalism by attacking American Protestantism and the growing mythology of the nation’s Puritan origins. Douglass’s early speeches undercut the celebration of Puritan ancestry by Daniel Webster, George Bancroft, and others; provide a thick description of US antebellum religious persecution in both the North and South; and deploy missionary rhetoric to call on European Protestant churches to remake their US counterparts. For 1840s Douglass, slavery in the United States was not a result of the country failing to live up to its founding republican principles, an argument he would make in subsequent decades. Rather, the more radical and zealous appraisal of the country he offered at that time was that the country’s founding reliance on slavery and servitude meant that it was, at core, an apostate nation in need of Christian conversion.
Feminisms in African Hip Hop
Authors: Clark Msia Kibona 
Published: November 2018

Abstract
Women hip hop artists in Africa have created spaces for themselves within hip hop’s (hyper)masculine culture. They have created these spaces in order to craft their own narratives around gender and sexuality and to challenge existing narratives. This research uses African feminism as a broad lens through which to examine how these women artists present challenges to patriarchy, gender norms, and the politics of respectability that may or may not align with African feminist ideologies. In addition to resistance, this research examines how these artists use their art to construct their own dynamic and multidimensional representations in ways that find parallels within African feminisms. In this study, more than three hundred songs produced by women hip hop artists were surveyed. The study revealed diverse expressions of feminist identities, implicit and explicit rejections of patriarchy, and expressions of sexuality that included agency and nonconformity.

Η ευαισθητοποίηση των νέων και η αλλαγή των συνηθειών τους όσον αφορά στην προστασία του περιβάλλοντος και την εξοικονόμηση ενέργειας, θα είναι καθοριστικής σημασίας για την διατήρηση ενός βιώσιμου πλανήτη στο εγγύς μέλλον. Σε αυτό το πλαίσιο, η αντιμετώπιση της κλιματικής αλλαγής απαιτεί αρχικά την ενημέρωση και κατόπιν την αλλαγή νοοτροπίας και εφαρμογή συμπεριφορών φιλικότερων προς το περιβάλλον. Σε αυτό το κείμενο, παρουσιάζουμε μερικές εκπαιδευτικές πρακτικές STEM που αξιοποιούν συστήματα Διαδικτύου των Αντικειμένων με αισθητήρες (Internet of Things, IoT), σε συνδυασμό με κατάλληλα σχεδιασμένες εκπαιδευτικές δραστηριότητες διερευνητικής μάθησης. Η ενίσχυση της εκπαιδευτικής κοινότητας στην περιβαλλοντική εκπαίδευση των νέων έχει πολλαπλασιαστικό αποτέλεσμα, καθώς η υιοθέτηση ενεργειακά αποδοτικών συνηθειών επηρεάζει και το άμεσο οικογενειακό τους περιβάλλον. Ως ένα τέτοιο παράδειγμα, η πλατφόρμα του έργου GAIA αξιοποιεί πραγματικά δεδομένα από σχολικά κτίρια, και μπορεί να χρησιμοποιηθεί ως βάση για τη σχεδίαση εκπαιδευτικών δραστηριοτήτων STEM, αντλώντας δεδομένα από διάφορα περιβάλλοντα. Επιπλέον, προτείνεται η χρήση αισθητήρων για τη μέτρηση βασικών ωκεανογραφικών παραμέτρων όπως η θερμοκρασία, η αλατότητα, το διαλυμένο οξυγόνο, η αλκαλικότητα και η θολερότητα σε παράκτια περιβάλλοντα, η οποία δεν έχει εξεταστεί στο παρελθόν, ως ένα επόμενο βήμα για το σχεδιασμό εκπαιδευτικών σεναρίων αυτού του τύπου.

Published: November 2018

Aims The aims of this study were to review the surgical technique for a combined femoral head reduction osteotomy (FHRO) and periacetabular osteotomy (PAO), and to report the short-term clinical and radiological results of a combined FHRO/PAO for the treatment of selected severe femoral head deformities. Patients and Methods Between 2011 and 2016, six female patients were treated with a combined FHRO and PAO. The mean patient age was 13.6 years (12.6 to 15.7). Clinical data, including patient demographics and patient-reported outcome scores, were collected prospectively. Radiologicalally, hip morphology was assessed evaluating the Tönnis angle, the lateral centre to edge angle, the medial offset distance, the extrusion index, and the alpha angle. Results The mean follow-up was 3.3 years (2 to 4.6). The modified Harris Hip Score improved by 33.0 points from 53.5 preoperatively to 83.4 postoperatively (p = 0.03). The Western Ontario McMasters University Osteoarthritic Index score improved by 30 points from 62 preoperatively to 90 postoperatively (p = 0.029). All radiological parameters showed significant improvement. There were no long-term disabilities and none of the hips required early conversion to total hip arthroplasty. Conclusion FHRO combined with a PAO resulted in clinical and radiological improvement at short-term follow-up, suggesting it may serve as an appropriate salvage treatment option for selected young patients with severe symptomatic hip deformities.

Aims Our unit was identified as a negative outlier in the national patient-reported outcome measures (PROMs) programme, which has significant funding implications. As a centre that carries out a high volume of unicompartmental knee arthroplasty (UKA), our objectives were: 1) to determine whether the PROMs programme included primary UKA when calculating the gain in Oxford Knee Score (OKS); and 2) to determine the impact of excluding primary UKA on calculated OKS gains for primary knee arthroplasty. Materials and Methods National PROMs data from England (2012 to 2016) were analyzed. Inclusion of UKA cases in the national PROMs programme was determined using clinical codes. Local OKS gain was calculated for UKA and TKA and compared with the published PROMs results for 2012/13. Results Use of the recommended codes for primary UKA excluded 99.6% of UKAs locally and 97% nationally from PROMs programme analysis. Inclusion of primary UKAs in PROMs analysis improved our OKS gain from 15.1 (below average) to 16.3 (above average) for 2012/13 for primary knee arthroplasty. Conclusion Exclusion of UKA patients from the PROMs programme is a nationwide issue that potentially introduces bias when comparing OKS gain between centres. Where commissioning decisions are based on routinely collected data, it is imperative that the underlying methodology is appropriate to generate valid results.

Published: November 2018

Objective: Despite the tortuous course of primary root canal system, a paradigm shift occurred from conventional hand files to rotary system, which lead to faster, cost-effective, uniform and predictable fillings. One of the many advantages being, reduction in post-operative pain with the use of rotary system. Many rotary file systems were introduced, with the recent one, the Kedo-S. So the present study aimed to compare and evaluate the post – operative pain after pulpectomy using K-files, MTwo files and Kedo-S files in deciduous molars. Material and Methods: 75 teeth were randomly divided into three groups (group A – K-files, group B - Kedo-S files and group C - MTwo files) for pulpectomy of primary molars. Post – operative pain was assessed every 6,12,24,48 and 72 hours using facial pain scale. Results: 44% of volunteers in K-file group had moderate pain followed by Kedo-S group that is 8% and then MTwo files that is 4%. Conclusion: The least post-operative pain was found in Mtwo group followed by Kedo-S group and K-file group.KeywordsPulpectomy; Post-operative pain; MTwo; Kedo-S.

Published: November 2018

Objective: To evaluate the visual perception of surface gloss of resin composite under different illuminants by different observers. Material and methods: twelve cylindrical specimens (6mm x 1mm) were fabricated using a nanofilled resin composite (Z350, A2E shade) in order to compare different observers and to determine the limit of perceptibility of surface gloss. Bovine tooth specimen with similar dimensions was obtained for the comparison of different illuminants. Polishing of resin specimens was performed resulting in 6 groups, presenting surface gloss values at 10, 25, 40, 55, 70, and 85 GU (gloss units), measured by glossmeter (NOVOCURVE). Fifteen individuals were selected: 5 lay-person, 5 undergraduate students, and 5 dental professionals. Participants observed the specimens in a light booth (Gti lightbox) under three different illuminants, and rated the possible combinations between resin specimens or with the bovine enamel specimen (85GU). Data obtained were analyzed by PROBIT non-linear regression analysis (?=0.05). Results: Differences were observed among types of illuminants (p=0.042) and ?GU (p=0.004), with no interaction between factors (p=0.139). The fluorescent light presented lower surface gloss perceptibility values in relation to incandescent light. There was no influence by type of observers (p =0.598). The surface gloss perception limit was 17.6 GU under the presented tested conditions. Conclusion: the illuminant type influenced perception of gloss, with lower percentage of perceptibility for fluorescent light, while such perceptibility was not influence by different observers.

Documentos etnográficos y dispositivos de memoria. El uso de la imagen y los aportes de Walter Benjamin en los espacios culturales ­santafesinos:
Authors: De Jesús Jullier Yamila Del Corazón 
Published: December 2018

El Tríptico de la Imaginación es un proyecto del Ministerio de Cultura e Innovación de la Provincia de Santa Fe. Está compuesto por tres espacios (El Molino, La Redonda y La Esquina Encendida), cada uno con características particulares que componen su estética, su propuesta pedagógica y artística. Este trabajo se propone analizar El Molino, Fábrica Cultural, donde el uso de la imagen es fundamental ya que carga de sentido al espacio, lo completa y articula con la técnica artesanal y la poética, conjugando así varias formas de vivir el arte y la artesanía. En El Molino se propone un acercamiento de la sociedad a los espacios culturales, así como una nueva construcción de las miradas sobre el arte que rompen con las ideas tradicionales, las interpela y pone en discusión. Procuro observar estas nuevas formas y miradas desde mi propia articulación conceptual, gestada enuna ­experiencia subjetiva con el espacio, enlazando las corrientes de los Estudios Visuales, principalmente los aportes de Inés Dussel (2009), con la propuesta de Walter Benjamin (1936) sobre el arte y la reproductibilidad técnica. Para ello me centraré particularmente en un dispositivo lúdico–pedagógico de El Molino: «La Gioconda y sus intervenciones».
El cine: entre el relato histórico, el arte y la política. La producción de cine documental de los años 60 y 70 en Santa Fe:
Authors: Carril Alejandra Cecilia 
Published: December 2018

Parafraseando a Badiou (2005), podemos decir que una mirada filosófica del siglo XX no se preocuparía tanto por saber qué pasó sino que se centraría en indagar qué se pensó en esa época. Analizar expresiones culturales puede darnos indicios de esa subjetividad así como del contexto histórico de producción. Este trabajo pretende proximarse a la producción cultural de los años 60 y 70 en Argentina sin desconocer sus diálogos y contrapuntos con tendencias artísticas latinoamericanas y europeas. Centraremos la mirada en la producción cinematográfica de la época y analizaremos en particular una selección de filmes documentales realizados en las décadas del ’60 y ’70 en el marco de la Escuela Documental de Santa Fe perteneciente al Instituto de Cinematografía de la Universidad Nacional del Litoral. En la primera parte se discuten las conceptualizaciones de cultura para definir un posicionamiento que permita indagar en torno a lasrelaciones entre arte y política en los años 60 y 70. En el segundo apartado se plantean las tensiones y los diálogos entre regionalismo e internacionalismo presentes en las expresiones artísticas de Latinoamérica en esos años y en particular en el nuevo cine latinoamericano. En tercer lugar se analiza de qué manera se evidencia la tendencia del nuevo cine latinoamericano en un corpus de realizaciones de la Escuela Documental de Santa Fe (Argentina, 1956–1976) con el fin de indagar las imbricaciones entre arte y política en los ’60–’70 a nivel regional (Litoral). En el apartado cuarto se exploran las opciones estéticas y estrategias retóricas empleadas en el corpus documental y se brindan elementos para poner en debate algunas nociones como cine político y cine militante. En el último apartado se plantea a modo de pregunta si en los filmes analizados es posible hablar de una actualización de los lenguajes cinematográficos y las estéticas europeas contemporáneas sin caer en la idea de subordinación a influencias extranjeras.

With the dramatic rise of eco-Marxism in recent years, a corresponding revolution has been taking place in studies of the human-nonhuman animal relationship. Previous critical analyses with respect to the position of animals in human society have been largely dictated by animal-rights discourse, more recently represented by figures such as Peter Singer. Many of these analyses contend that Karl Marx, Marxism, and historical materialism understand the human-nonhuman animal relationship through a dualist, "speciesist," or human-centric, framework—a critique most famously championed by pioneering ecosocialist Ted Benton. This issue is dedicated to analyzing the theoretical propositions underlying Marx's analysis and to demonstrate the antispeciesist and antidualist aspects of his evolutionary-materialist understanding.

This research is background by the idea that novels are works that do not only highlight the aesthetic elements of language, but as a medium or means for authors to convey their mission and message. The novel is full of meaning, either clear or implied. Mission, motif, purpose of the author represented through the fictional characters he constructed. The purpose of the research is to reveal the form ideological hegemony in the novel Ketika Cinta Bertasbih (KCB) creation Habiburrahman el Shirazy. Research on novels KCB with the Gramsci hegemony approach the author’s knowledge is based search in online journals indexed doaj.org, in the last five years it has not been found. The research method used is descriptive qualitative. The research approach used Gramsci hegemony. The results of the research show, central figure in a novel like Khairul Azzam dan Anna Althafunnisa able to deal with life’s problems well (happines), because they believe and carry out ther ideology anda religious values. The main problem thet emerged from the two figures was like education, romance, and marriage. The process of hegemony that occurs between two figures and most of the other characters went will, so that able to dampen potential conflict between character.
