INTRODUCCIÓN. El propósito de este trabajo de investigación fue establecer el impacto de un programa fundamentado en aprendizaje-servicio y tutoría entre compañeros sobre el rendimiento académico del alumnado universitario de nuevo ingreso, así como explorar sus efectos sobre determinadas competencias del alumnado universitario de último curso. MÉTODO. La muestra estuvo compuesta por 71 estudiantes, 48 de nuevo ingreso, distribuidos aleatoriamente en un grupo experimental (N = 24) y control (N = 24), y 23 de cuarto curso que actuaron como alumnado tutor. El rendimiento académico se evaluó mediante el expediente académico, mientras que la autorregulación del aprendizaje y las habilidades sociales se evaluaron a través del Motivated Strategies for Learning Questionnaire (Pintrich, Smith, García, y McKeachie, 1991) y la Escala de Habilidades Sociales (Gismero, 2000), respectivamente. La intervención consistió en 20 sesiones individuales de tutoría altamente estructuradas con el alumnado de nuevo ingreso, realizadas por alumnado de cuarto curso, previamente entrenado en tres sesiones de formación. RESULTADOS. Los resultados derivados de las comparaciones entre los grupos experimental y control del alumnado de nuevo ingreso revelan diferencias estadísticamente significativas a favor del grupo experimental en rendimiento académico, mientras que los resultados de las comparaciones pretest-postest sobre autorregulación del aprendizaje y habilidades sociales del alumnado tutor muestran igualmente diferencias estadísticamente significativas en la fase postest. DISCUSIÓN. Este trabajo aporta evidencias empíricas sobre la potencia y validación del modelo causal de intervención del programa para abordar los procesos de ajuste académico y social del alumnado de nuevo ingreso a la vida universitaria, así como sobre los posibles beneficios de participar en este tipo de programas para el alumnado de cursos superiores.
When heritage laws and environmental laws collide: Artisans, guilds and government support for traditional crafts in Tokyo
Authors: Pontsioen Robert 
Published: November 2019

Abstract
This article examines the legislative basis and operational effectiveness of the national and prefectural systems for designating and promoting traditional crafts in Tokyo. Traditional artisans participate in these systems primarily through their involvement in kumiai ('artisan guilds'), whose historical background and organizational structure are briefly summarized. To evaluate the usefulness of government support for contemporary craft practitioners, four broad and interrelated categories of kumiai activities are examined: promoting craft business, maintaining and enhancing craft skills and product quality, securing the future of craft traditions, and procuring craft materials. These goals are reflected in the frameworks of national and prefectural legislation that aims to support the efforts of kumiai. However, these goals and the resulting legislation have created a sustained discourse of tension palpably felt by many crafters themselves: the clash between laws designed to protect or promote 'traditional' crafts and other laws that aim to safeguard ecology or animal welfare. Examination of this tension as it is understood and discussed by artisans themselves reveals that, although the positive impact of traditional craft designation systems is widely recognized, it is also perceived that incompatible environmental protection laws can negatively affect their business and threaten the long-term sustainability of craft traditions.
The rise of experimental film festivals in India
Authors: Nori Gauri 
Published: November 2019

Abstract
This article will examine the emergence of independent platforms to screen radical and alternative cinema in India by tracing two case-studies: Experimenta, a biannual festival curated by Shai Heredia, and The New Medium section curated by Shaina Anand. While Experimenta has remained largely independent, relying on the support of established artists and cultural organizations, The New Medium section has managed to secure its place within the programme of the MAMI Mumbai Film Festival (MFF). Although their approach may differ, both curators are committed to promoting a culture of moving image experimentation in the country. Drawing on first-hand observations, interviews and scrutinizing festival ephemera, this article aims to identify the curatorial practices and strategies that have established these alternative film festivals both within the international film festival network and the larger film community in the country.
Little cinema culture: Networks of digital files and festival on the fringes
Authors: Mukherjee Madhuja 
Published: November 2019

Abstract
This article reflects on the contemporary digital turn that has transformed our audio-visual experiences fundamentally, and has affected mainstream control over production and circulation of data. Clearly, such conditions have reinvented the problematical relation between producer and receiver. In relation to such circumstances, the article focuses on marginal film festivals, especially the TENT 'Little Cinema International Festival' for experimental films and new media-art, held in Kolkata, India, since 2014. 'Little Cinema International Festival', on one hand, showcases international packages such as those from Berlinale; on the other hand, it presents curated programmes comprising videos made by first-time filmmakers from India. The article deliberates on the broad and long drawn contexts of 'festivals' and artistic endeavours, as well as the formal contours of the videos, which generate spaces for dialogues, both within the filmic text, and in the milieus in which these are shown. The emphasis on the thriving 'amateur' practice also draws attention to 'Little Magazine', 'Little Theatre' and 'Little Film' practices in West Bengal, as well as contemporary new-media transactions, which has transmediated into newer modes of articulations.
Corporate Law, Government Intervention and Corporate Ownership Structure
Authors: Miao Miao , Liu An , Shi Jiaming 
Published: November 2019

Abstract
We compare the influence of legal and political factors on the corporate ownership structure of Chinese listed companies. We find that: (1) the improvement of corporate law quality and the less government intervene on firms lead to a decrease in corporate ownership concentration; (2) compared with the provincial corporate law performance, the effects of the provincial government intervention on the concentration of ownership is relatively significant; (3) the impact of government intervention on corporate ownership structure of state-owned firms are larger than that of private firms, whereas the impact of provincial corporate law implementation performance is more significant in samples of private firms. The policy implications are that most China’s SOE reform measures have yet not cure the crux. The success of the reform may primarily depends on the re-examination and restructure of the political institutions.

Published: November 2019

Abstract

Background
Differentiation between hemorrhagic and ischemic stroke is currently made by brain imaging or analyzing blood and cerebrospinal fluid (CSF) samples. After describing a new drainage route from brain to nasal mucosa, nasal exudate samples can be considered a new and promising source of biomarkers. Saliva can also be evaluated.

Methods
We determined iron in nasal exudate and saliva samples from patients of acute stroke during the first 48 h from onset. A simple, non-invasive sampling procedure was employed to obtain information from the brain. Samples were taken with a pre-weighed swab, solved in a 2% nitric acid solution and iron was measured by inductively coupled plasma-tandem mass spectrometry (ICP-MS/MS).

Results
A significant difference in the dispersion of results of iron concentration for both stroke subtypes was observed in nasal exudate samples. The interquartile range was 0.608 nmol mg−1 of iron for hemorrhagic strokes and only 0.044 nmol mg−1 for ischemic strokes. In saliva samples, however, the values were 0.236 vs. 0.157 nmol mg−1. A cut-off limit of 0.102 nmol of iron per mg of nasal exudate provides a methodology with a 90% of sensitivity and a 90% of specificity. The value of the area under (AUC) the receiver operating characteristic curve (ROC) for nasal exudate samples is 0.960, considered as very good in which regards to its predictive value.

Conclusions
Non-invasive samples of nasal secretion have allowed obtaining, for the first time, information from the brain. Determination of iron in nasal exudate by ICP-MS allowed differentiation between ischemic and hemorrhagic strokes.
Effect of pulp fibers on the surface softness component of hygiene paper
Authors: Park Jung Yoon , Melani Lili , Lee Hyeonggyu , Kim Hyoung Jin 
Published: November 2019

AbstractThis study analyzed the effect that pulp fibers have on the surface softness component of hygiene paper. The surface softness component has more of an influence on the evaluation of subjective softness results than the bulk softness component. Using the surface softness measurement technique, this study aimed to evaluate the effect that fibers have on the softness of hygiene paper substrate via objective numerical values to measure the surface softness component of hand sheets composed of various pulp species. The results indicate that coarseness effects had the largest effect on softness among the various fiber characteristics, such as average fiber length, width and coarseness. As fiber coarseness increased, a rough surface formed, which resulted in an increase in the mean deviation from the average friction (MMD). Nonwood fibers had long fiber length and low coarseness, which enables the production of hygiene paper with high strength and softness. This study hopefully could lead to the development of various process technologies that may improve the softness of hygiene paper products.
Effect of ghrelin on VEGF-B and connexin-43 in a rat model of doxorubicin-induced cardiomyopathy
Authors: Elhadidy Mona G. , Elmasry Ahlam , Rabei Mohammed R. , Eladel Ahmed E. 
Published: November 2019

Abstract

Background
Since their discovery in the early 1960s, doxorubicin (DOX) remains the most effective anticancer drug. However, this drug has confirmed to be a double-edged sword because it causes a cardiomyopathy that leads to congestive heart failure. Ghrelin, a multi-functional peptide, plays an important role in cardiovascular protection. Therefore, we investigated the effects of ghrelin on vascular endothelial growth factor-beta (VEGF-B) and connexin-43 (Cx43) expression in DOX-induced cardiomyopathy.

Methods
Forty adult male rats were divided randomly into four groups: normal, normal + ghrelin, DOX-induced cardiomyopathy, and DOX-induced cardiomyopathy + ghrelin. Biochemical and histopathological analysis, electrocardiograph (ECG), heart rate, systolic blood pressure (SBP), and immunohistochemical staining of VEGF-B and Cx43 were assessed for all rats in heart tissue specimens. The duration of the study was 2 weeks.

Results
DOX-induced cardiomyopathy in rats showed significant ECG changes such as prolongation of PR, QT, QTC intervals and ST segment, a decrease in amplitude and an increase in the duration of QRS complex, bradycardia, and a decrease in SBP. Also, rats in the DOX group showed myocardial histopathological damage in the form of severe fibrosis with decreased expression of Cx43 and a non-significant difference in expression of VEGF-B when compared to normal rats. Treatment with ghrelin resulted in a significant improvement in all the studied parameters and was associated with an increase in VEGF-B and Cx43 expression.

Conclusions
Ghrelin has a beneficial effect against DOX-induced cardiomyopathy which may be mediated through VEGF-B and Cx43 expression in the myocardium. Ghrelin is a promising cardioprotective drug in DOX-induced cardiomyopathy patients, but further studies are needed to evaluate its use.

Abstract

Background
Anxiety is a common ailment of high co-morbidity with epilepsy, a chronic neurologic disease characterized by recurrent seizures. Current drugs used for these conditions have several limitations such as disabling side effects, relapse, and ineffectiveness in certain population necessitating the search for alternative options. The aqueous leaf extract of Cymbopogon citratus (CYC) is widely used for its various health-promoting effects including relief of seizures and anxiety in ethnomedicine. This present study describes its effects on convulsions, anxiety-like behaviors, and social interaction in mice.

Methods
Male Swiss mice were pretreated orally with CYC (25, 50, and 100 mg/kg), diazepam (1 mg/kg), or distilled water (10 mL/kg) 60 min before induction of convulsions with intraperitoneal (i.p.) injection of picrotoxin (10 mg/kg), pentylenetetrazole (PTZ; 85 mg/kg), or isoniazid (300 mg/kg). The animals were then observed for the occurrence of seizure for 30 min or 2 h for isoniazid. The effects of CYC on anxiety-like behaviors, social interaction, and spontaneous motor activity (SMA) were evaluated in naive mice.

Results
CYC (25–100 mg/kg) did not prevent convulsions nor delay the latency to convulsions induced by picrotoxin, PTZ, or isoniazid. Pretreatment with CYC (50 and 100 mg/kg, p.o) produced anxiolytic-like effect, decreased SMA, and also enhanced social interaction behavior in naive mice.

Conclusions
The results of this study suggest that CYC did not exhibit an anticonvulsant property in mice injected with picrotoxin, PTZ, or isoniazid, but its anxiolytic-like activity and social interaction-promoting effect might be of benefit as an adjuvant in improving the quality of life of epileptic patients.

Published: November 2019

Abstract
Diabetes mellitus (DM) is a group of metabolic diseases related to the dysfunction of insulin, causing hyperglycaemia and life-threatening complications. Current early screening and diagnostic tests for DM are based on changes in glucose levels and autoantibody detection. This review evaluates recent studies on biomarker candidates in diagnosing type 1, type 2 and gestational DM based on omics classification, whilst highlighting the relationship of these biomarkers with the development of diabetes, diagnostic accuracy, challenges and future prospects. In addition, it also focuses on possible non-invasive biomarker candidates besides common blood biomarkers.

Published: November 2019

Abstract

Background
Cholesterol metabolism has dramatically changed under hyperthyroid status. However, a combination of hyperthyroidism and cholecystolithiasis is very rare.

Case presentation
We report a case of cholelithiasis accompanied by hyperthyroidism in a 13-year-old girl who had recently lost 13 kg of weight (from 53 to 40 kg) in 1 month without loss of appetite. Ultrasonography showed multiple hyperechoic areas with acoustic shadowing in the gallbladder. Thyroid function tests showed that her serum free triiodothyronine (T3) and thyroxine (T4) levels were elevated and the thyroid-stimulating hormone level was decreased. In addition, serum thyrotropin receptor antibody and thyroid-stimulating antibody were detected. The final diagnosis was cholelithiasis with Graves’ disease. Thiamazole ingestion was started immediately after the diagnosis, and laparoscopic cholecystectomy was performed 33 days after hospitalization.

Conclusions
Massive and sudden weight loss could be a risk factor for gallstone formation in children. In addition, hyperthyroidism has the potential to promote cholelithiasis via cholesterol metabolism.
Significance of the routine first-trimester antenatal screening program for aneuploidy in the assessment of the risk of placenta accreta spectrum disorders
Authors: Penzhoyan Grigory A. , Makukhina Tatiana B. 
Published: November 2019

Abstract

Objective
To select a group at high risk of placenta accreta spectrum disorders (PAS) based on the data of serum screening in the first trimester.

Methods
A retrospective analysis of 48 patients with abnormal placental location (AP), including placenta previa (PP) only (n = 23) and PP and PAS (n = 25), was performed. Additionally, the AP group was divided depending on the blood loss volume: not higher than 1000 mL (LBL) (n = 29) and higher than 1000 mL (HBL) (n = 19); diagnostic term of PAS by ultrasound, data pregnancy-associated plasma protein-A (РAРР-A) and free β subunit of human chorionic gonadotropin (free β-hCG) multiple of median (MоM) at 11+0–13+6 weeks of gestation were evaluated. Serological markers were compared with the data of 39 healthy pregnant women with scar after previous cesarean section and normal placental location (control).

Results
The mean gestation at diagnostic term of PAS was 29 weeks. PAPP-Р MоM [mean (M) ± standard deviation (SD)] was: in controls, 1.07 ± 0.47; in the AP group, 1.59 ± 0.24; in PP, 1.91 ± 1.52; in PAS, 1.30 ± 0.85; in LBL, 1.37 ± 1.20; in HBL, 1.91 ± 1.24. The difference between control/AP, control/PP, control/PAS, PP/PAS, control/LBL, control/HBL and LBL/HBL was Р = 0.256, 0.145, 0.640, 0.311, 0.954, 0.025 and 0.09, respectively. Free β-hCG MoM (M ± SD) was: in controls, 1.08 ± 0.69, in AP, 1.31 ± 0.96; in PP, 1.46 ± 0.19; in PAS, 1.16 ± 0.65; in LBL, 1.30 ± 0.06; in HBL, 1.32 ± 0.78. Comparison of free β-hCG AP with controls and between subgroups did not reveal a significant difference.

Conclusion
Underestimation of PAS risk factors in pregnant women with AP leads to late diagnostics of pathology only in the third trimester. The assessment of the РAРР-A level in the first trimester may be helpful for the early prognosis of pathological blood loss at delivery for pregnant women with AP and for forming the high-risk group for PAS.
Kierkegaard’s Aesthete in Either/Or: Using Hegelian Mediation in Everyday Life
Authors: Davidshofer Claudine 
Published: November 2019

Abstract
This paper discusses how Kierkegaard’s aesthete in Either/Or’s “Diapsalmata” and “Rotation of Crops” attempts to apply Hegel’s principle of mediation to everyday decision-making. This paper has two main goals: First, it provides an in-depth analysis of exactly how the aesthete’s approach to decision-making follows the dialectical pattern of Hegelian mediation. Second, it argues that even though the aesthete meets with unfortunate results, the aesthete cannot be so easily dismissed. The aesthete’s Hegelian perspective is still relevant to daily life because it provides an insightful view into how we ourselves sometimes approach decisions and cope with the difficulty of making decisions.
From body part to applicative: Encoding ‘source’ in Murrinhpatha
Authors: Nordlinger Rachel 
Published: November 2019

AbstractMurrinhpatha (non-Pama-Nyungan, Australia) is typologically unusual in having a single applicative construction with the semantics of source/malefactive, but never benefactive. In this paper I discuss the development of this applicative from an incorporated body part meaning ‘hand’. I show that the applicative developed from a reanalysis of the external possession construction; and that the applicative morphology developed from the incorporated body part, rather than from a verbal or adpositional source. This contributes to our understanding of the typology of applicative constructions and also highlights the value in exploring the complex verbal constructions of polysynthetic languages to inform our understanding of grammaticalisation possibilities.
Veitstanz und Fortschritt
Authors: Moll Björn 
Published: November 2019

Abstract
This article focusses on the discourse surrounding ›projectors‹, autoentrepeneurs, who made plans for innovations of any kind and tried to have potential financiers promote them, from the Baroque to German Romanticism. While the role of projectors in the history of science has been the object of historical study, there is a lack of research regarding the concept’s trajectory and its semantic variation. In the early modern period, the necessity of innovation was emphasized, but also the contingency of project proposals. During the Enlightenment, the tradition of the approval of project-making continued, but projects became detached from projectors. In the late 18th century, the idea of speculation and the fantastic transformed within the area of creativity, due to the primacy of imagination and genius. What happened to the talk about projectors and their ways of self-fashioning after the disappearance of the social figure? What enabled authors to refer to projectors and how was their role historically discussed? Projectors served as a topos of insanity or deception or a sign of unprofessionalism (as shown in examples by Goethe and Schiller). Romanticism carried with it the positive connotations of the project, but also reinterpreted its negative aspects, such as the value of incompletion, insanity and alternative ways of work.

Published: November 2019

Abstract
Aluminum-2.5 copper-1.5 magnesium alloy is an important aerospace alloy and is extensively used in the fabrication of aerospace and aircraft systems. Hot working parameters for the alloy have been generated through hot isothermal compression testing at different temperatures (673–748 K at an interval of 25 K) and at strain rates of 0.01 to 10 s−1. Hot workability of alloy has been established by using the instability criteria and validating the same with microstructural evolution. Further, the Holloman parameter was calculated, and the constitutive equation has been derived. Optimum parameters for the hot deformation were evolved avoiding the unstable metal flow regimes of 673–760 K at 0.1 to 1 s−1. Maximum power efficiency in the dynamic recrystallization domain of the alloy is found to be ∼0.6, indicating stable material flow during hot deformation. Strain rate sensitivity (m) value of 0.25–0.35 is observed in the stable regime at strain rates of 0.01–0.1 from 698 to 748 K indicating superplastic flow domain. Very fine recrystallized grains can be seen at higher temperatures greater than 723 K and lower strain rates of 0.1 and 0.01 s−1, which grow further with an increase in temperature, indicating onset of grain growth.
