Published: November 2020

Online education often struggles to maintain a consistent, high quality academic experience. High attrition rates and low student satisfaction continue to challenge higher education providers. We present an innovative public-private partnership that delivers a resources-sufficient model of fully online postgraduate education with high levels of academic student support in an unbundled approach. The partnership overcomes the challenges that plague online education by leveraging learning analytics to provide highly responsive student support, 7 days a week and in the evenings. The success of this model is its ability to ameliorate problems inherent in online education. This includes the lack of ongoing staff training and support to successfully teach online, staff availability when students need support and insufficient staff-student ratios. As the sector moves towards a digitally integrated future, our model of online education illustrates how a public-private partnership can provide online learning that is effective as measured by high rates of student retention and transition, satisfaction, and academic success. We argue our resources-sufficient model provides a transformational roadmap for scaled online learning that creatively reimagines supported, personalised, engaged and student-centred digital learning as the sector moves towards a digitally integrated future.
Implications for practice or policy

Public-private partnerships can represent a rebundling of the university that explicates how the university should work to provide responsive, supported, and high-quality online education.
A resources-sufficient model of online education characterised by high levels of ongoing staff training, learning analytics to track student engagement, and optimum staff-student ratios, increases student retention and transition, satisfaction, and academic success.
Student engagement systems that leverage learning analytics can work to increase students’ academic success and decrease attrition rates.
Just when I needed you most: Establishing on-demand learning support in a regional university
Authors: Wilson Gail , McAuley Andrew , Ashton-Hay Sally , Van Eyk Tina 
Published: November 2020

This article discusses the experiences and challenges of introducing a third-party learning support provider into the teaching and learning culture at Southern Cross University (SCU), a regional university with campus locations in New South Wales and Queensland. The provider was engaged to extend online study support after-hours to first year students to complement the on-campus and online academic skills consultations available during business hours. The case study covers a 2015 pilot, a wider roll-out in 2016, and finally, a 2017 university-wide access via the intranet as well as through nominated units. The project team collaborated, planned, and prepared for adding third-party student support with specific strategies used to implement institutional cultural change. The case study offers implications for practice and policy across the higher education sector through the lessons learned, including the need for a complementarity of services approach with existing student services, a team-based strategic approach with a provider representative, and the benefits from open and positive communication. The partnership between SCU and the third-party provider evolved to the mutual benefit of both organisations. Students received support and feedback when they needed it most, academic staff revitalised coursework, and the third-party provider fine-tuned a targeted service for the institution.
Implications for practice or policy:

Situate the academic skills support services provided in-house and the service provided by the third-party provider as complementary to each other.
Re-enforce this complementarity in all communication with students and academic staff.
Adopt a team-based approach to planning the introduction and implementation of a third-party provider’s services.
Utilise the provider’s strengths, such as data generation and reporting, that enable student usage information about the after-hours service to be disseminated across the university.

New media are the tools that support human’s intellectual functioning. For many people with disabilities they may become the sole opportunity for accessing information, communicating, learning or working. On the other hand, new media also provide a space for social interactions that could affect the process of coping with critical events, both ordinary and traumatic ones. The key concept for the discussion is internet-based social support, defined as support available online to a person dealing with a critical event which needs to be overcome with external resources coming from virtual groups comprising people experiencing difficulties of a similar nature, in the past or currently. The author posed the question whether internet social support is ubiquitous, and what it manifests itself. To answer this, she conducted quantitative and qualitative research. The data collected then became thebasis for analysis and theoretical considerations.

The aim of the article is to show new perspectives of research and development of media, digital and information competences in the context of knowledge and research in (cyber) psychology. It draws attention to the functions of media education in relation to civil society, the society of knowledge, and the society of communication democracy. In the modern media civilization, these competences, acquired through formal and informal education, are the basis for conscious functioning in many social roles (eg citizen, consumer) and dealing with disinformation. The last part of the article is dedicated to shaping media competences in young children (2.5-7 years old), who should develop these skills under the care of an adult. The task of educational environments is the systematic implementation of home media education that facilitates the child's functioning in the environment of traditionaland new media.

Mirosław Wobalis, Digital Communicators – creators or imitators?, Interdisciplinary Contexts of Special Pedagogy, No. 23, Poznań 2018. Pp. 117–133. Adam Mickiewicz University Press. ISSN 2300-391X. DOI: https://doi.org/10.14746/ikps.2018.23.07
The article touches upon the issue of influence of modern digital media on the attitudes of recipients/ broadcasters (digital communicators) related to their creative activities. The first indication applies to the fact that the development of digital technologies introduces a new digital order of communication (from the primary order, through the secondary and hybrid order, to the digital order), which in turn provides communicators with a broad spectrum of new methods and tools of communication 0 including tools permitting creative activities. Second of all, it is noted that despite the mentioned rich offer of digital tools and the promotion of creative attitudes, digital media, in particular global social media, are dominated by attitudesof re-production related both to common re-distribution of existing content (sharing, copying and pasting, etc.), and even limiting creativity entirely (likes, tags). The remarks made are compared to opinions of digital media researchers and neurobiologists indicating on the one hand the weakening/ dissolution of the reception of content by digital media (the negative effect of multi-tasking), and on the other hand, the supersaturation of emotions related to the reception of content (negative influence of computer games). In conclusion, attention is turned to the necessity of establishing in contemporary communicators (on all levels of education) of digital communication competences, in particular the promotion of creative attitudesrelated to these competences.

Abstract

Background
Association between early diagnosis of chronic kidney disease (CKD) and low morbidity and mortality rate has been proven. Thus, tools for early CKD diagnosis are vital. Ultrasonography has been widely used to diagnose and monitor the progression of CKD.

Objectives
To determine the performance of selected renal ultrasonographic parameters for the diagnosis of early CKD.

Methods
In a cohort of patients diagnosed with CKD (n = 100), diagnostic performance of ultrasonographically measured renal length (RL), renal cortical thickness (RCT), and parenchymal thickness (PT) was determined using receiver operating curve analysis; correlation of each parameter with the associated comorbidities and serum creatinine (Scr) levels was also determined. Severity of CKD was graded with estimated glomerular filtration rates (eGFR).

Results
Of all patient participants, 85 had severity grades 2 or 3. Mean (standard deviation) Scr was 1.88 (0.60) mg/dL; eGFR was 43.3 (11.85) mL/min/1.73 m2. RL was 9.01 (0.83) cm, PT was 1.32 (0.22) cm, and RCT was 6.0 (0.10) mm. PT and RCT were positively correlated with eGFR (P = 0.01 and 0.002, respectively). Early CKD was better predicted by PT (area under the curve (AUC) 0.735; 82% sensitivity; 30% specificity; 68% positive predictive value (PPV)) and RCT (AUC 0.741; 82% sensitivity; 48% specificity; 51% PPV); severe CKD was better predicted by RL (AUC 0.809; 67% sensitivity; 26% specificity, 45% PPV; 13% negative predictive value).

Conclusion
Index ultrasonic parameters show a diagnostic role in different stages of CKD. The index ultrasound and biochemical parameters showed a complementary role in predicting renal dysfunction.
Minkowski inequalities and constrained inverse curvature flows in warped spaces
Authors: Scheuer Julian 
Published: November 2020

Abstract
This paper deals with locally constrained inverse curvature flows in a broad class of Riemannian warped spaces.
For a certain class of such flows, we prove long-time existence and smooth convergence to a radial coordinate slice.
In the case of two-dimensional surfaces and a suitable speed, these flows enjoy two monotone quantities.
In such cases, new Minkowski type inequalities are the consequence.
In higher dimensions, we use the inverse mean curvature flow to obtain new Minkowski inequalities when the ambient radial Ricci curvature is constantly negative.
Averroes’s Unity Argument Against Multiple Intellects
Authors: Ogden Stephen R. 
Published: November 2020

AbstractAverroes (Ibn Rushd) is well-known for his controversial thesis that there is only one separate intellect for all humankind. This article provides a detailed analysis of Averroes’s Unity Argument from hisLong Commentary on De Anima, which argues from unified intelligible concepts to a single transcendent intellect. I set out the Unity Argument in its textual and philosophical context, explain exactly how the argument works on a new interpretation of its infinite regress (based on Averroes’s other assumptions about the mind-dependence of universals), and offer some brief suggestions as to how it might be further evaluated in light of alternative ancient and medieval theories. Ultimately, I demonstrate that the Unity Argument is Averroes’s most important philosophical argument for his distinctive view of intellect.

Resumen

Objetivos
La enfermedad de Graves (EG) es una enfermedad secundaria a la presencia de autoanticuerpos anti-receptor de TSH (TRAb) que estimulan la producción de hormonas tiroideas. La medida de la concentración de TRAb es crucial para su diagnóstico etiológico. Los objetivos de este estudio fueron 1. Comparar dos métodos de medida de TRAb por quimioluminiscencia con el método habitual del laboratorio (TRACE-inmunofluorescencia). 2. Determinar la validez diagnóstica de los tres métodos.

Métodos
Estudio retrospectivo de 194 pacientes con petición de TRAb, analizado por: inmunofluorescencia (Kryptor, ThermoFisher) y quimioluminiscencia (Immulite, Siemens y Maglumi, Snibe). Validación clínica: revisión de historias clínicas y clasificación según función tiroidea. Análisis estadísticos: Variables cuantitativas, coeficiente de correlación intraclase (CCI) y gráfica de Bland-Altman, diferencia de medias (Dm). Variables cualitativas, dicotomizadas según puntos de corte, coeficiente Kappa. Correlación: Pearson y regresión de Passing-Bablok. Se estudió la validez diagnóstica de los tres métodos.

Resultados
Kryptor-Immulite: Dm: 1,2 (IC95%: –16 a+18). Passing-Bablok: Error constante (IC95%: –0,8349 a–0,5987). Error proporcional (IC95%: 0,7862–1,0387). CCI: 0,86 (IC95%: 0,82–0,89). Coeficiente-Kappa: 0,68 (IC95%: 0,59–0,78). Kryptor-Maglumi: Dm: −0,3 (IC95%: −12 a+12). Passing-Bablok: Error constante (IC95%): −0,7701 a+0,1621. Error proporcional (IC95%): 0,8571 a 1,3179. CCI: 0,93 (IC95%: 0,89–0,97). Coeficiente-Kappa: 0,53 (IC95%: 0,32–0,74). La enfermedad de Graves se confirmó en 113 pacientes (Kryptor: mejor especificidad y valor predictivo positivo [VPP]. Immulite: mejor sensibilidad y valor predictivo negativo [VPN]).

Conclusiones
Los tres métodos presentan buen rendimiento diagnóstico en la enfermedad de Graves, con resultados superponibles en la intercomparación de Bland-Altman, aunque el estudio de regresión y concordancia muestran no intercambiabilidad y presencia de sesgos.

Abstract

Objectives
Coronavirus disease 2019 (COVID-19) is widely spreading and represents a critical threat to global health. In the fight against this pandemic, provincial hospitals urgently need rapid diagnostic of COVID-19 infected patients to avoid collapsing of emergency units. However, the high demand of patients with severe acute respiratory symptoms limits the fast delivery of results by the gold standard method reverse transcription-polymerase chain reaction real time (rRT-PCR) for the identification of COVID-19 positive pneumonia. The principal aim is to find other useful laboratory indicators to assist rRT-PCR tests and to help controlling of this outbreak.

Methods
Blood, coagulation and inflammatory parameters were collected from a total of 309 patients classified as negative (128) and positive (181) rRT-PCR test groups. Patients were classified as positive by molecular diagnostic test.

Results
Leukocyte count (WBC), neutrophils count, lymphocytes count and lactate dehydrogenase (LDH) were statistically different between both groups of patients. The use of LDH/WBC ratio increases the diagnostic performance with the best area under the curve (0.783), sensibility (82%) and the best percentage (80.5%) of correctly identified COVID-19 positive patients.

Conclusions
The combination of predictive LDH/WBC ratio with clinical illness features could help in medical management of patients and improve the technical resources of hospitals, especially in a critical scenario with a large shortage of medical equipment and lack of reagents for performing rRT-PCR.
Circ_0084043 promotes cell proliferation and glycolysis but blocks cell apoptosis in melanoma via circ_0084043-miR-31-KLF3 axis
Authors: Wu Songjiang , Tang Yuhan , Liu Wenli 
Published: November 2020

AbstractMelanoma is an aggressive malignant tumor. The crucial role of circular RNAs has been documented in many types of cancer, including melanoma. The objective of this study was to uncover the function of circ_0084043 in the biological process of melanoma and associated mechanism of action. The expression of circ_0084043, miR-31, and Krüppel-like factor 3 (KLF3) was determined by qRT-PCR. Cell proliferation and apoptosis were monitored by the MTT assay and flow cytometry assay, respectively. The progression of glycolysis was evaluated according to the levels of glucose consumption, lactate production, and ATP concentration using appropriate detection kits. The relationship between miR-31 and circ_0084043 or KLF3 was predicted by the bioinformatics tool and ascertained by the dual-luciferase reporter assay. The protein levels of KLF3 and glucose transporter 1 (Glut1) were quantified by western blot. A xenograft model was established to ascertain the role of circ_0084043in vivo. As a result, circ_0084043 expression was reinforced in melanoma tissues and cells. Circ_0084043 knockdown inhibited cell proliferation, induced cell apoptosis, and restrained glycolysis. MiR-31 was a target of circ_0084043, and miR-31 deficiency reversed the role of circ_0084043 knockdown. KLF3 was targeted by miR-31, and KLF3 upregulation abolished the effects of miR-31 enrichment. Moreover, circ_0084043 knockdown impeded tumor growthin vivoand suppressed the level of Glut1 by modulating miR-31 and KLF3. Circ_0084043 promoted cell proliferation and glycolysis, and blocked apoptosis through the circ_0084043–miR-31–KLF3 regulatory axis in melanoma.

Published: November 2020

AbstractThis study compares the chemical composition of cockle (Anadara granosa) and some commercially important marine (Asian seabass Lates calcarifer, grouper Epinephelus bleekeri, hardtail scad Megalaspis cordyla, longtail tuna Thunnus tonggol and Indian mackerel Rastrelliger kanagurta) and freshwater (sutchi catfish Pangasius hypophthalmus, Nile tilapia Oreochromis niloticus and eel Monopterus albus) fishes in Peninsular Malaysia. The results show that the proximate composition and trace metal content were significantly different (P < 0.05) among species investigated. The mean protein content was the highest in eel (19.1%) and the lowest in sutchi catfish (13.0%) and cockle (13.0%). The mean lipid content of Indian mackerel (3.9%) was higher than cockle (2.0%), followed by eel (1.3%) and longtail tuna (0.8%). The mean ash content was the highest in Indian mackerel (1.4%) and the lowest in cockle (0.9%). Zinc and manganese contents in cockle (Zn: 61.2 mg kg−1, Mn: 22.7 mg kg−1) were very high compared to other species investigated. The copper content was minimum in sutchi catfish (1.0 mg kg−1) and a maximum in the hardtail scad (11.7 mg kg−1). Trace metal content in sutchi catfish, Nile tilapia, grouper, longtail tuna, eel and cockle followed an order Zn > Mn > Cu, whereas Asian seabass, hardtail scad and Indian mackerel followed a different order Zn > Cu > Mn. Trace metal content in the tissue of the fishes examined was within safe limits for human consumption except Mn content in the cockle and Cu content in the hardtail scad, which is a matter of concern. When considering the daily fish fat, mineral and trace metal intake, marine fishes and shellfish are better than freshwater fishes.
A multimodal cognitive approach to aid the conceptualization of Spanish utterances with ‘se’
Authors: Lopez-Ozieblo Renia 
Published: November 2020

AbstractMost native speakers of Spanish are intuitively able to construct correct structures with the marker ‘se’. On the other hand, non-native speakers, even those at advanced proficiency levels, have difficulties producing most constructions with ‘se’. This is hardly surprising as the marker ‘se’, one of the most common words in Spanish, can convey highly pragmatic nuances with a variety of functions that are still much debated among linguists. This study analyses some of the most used functions of the marker in the oral production of 18 Peninsular Spanish speakers from a multimodal Cognitive Grammar approach, identifying how gestures might be employed by speakers to create or clarify meaning. Our results confirm that gestures are used differently depending on the function of the marker. Middle voices where ‘se’ marks high levels of subject involvement and/or energy co-occur with related gestures, while middle voices or impersonal structures, where the involvement and/or energy is low, co-occur more often with unrelated gestures, if any.
Diagramming discursive intentionality—A cognitive-pragmatic model of intentional verbs
Authors: Briese Joschka 
Published: November 2020

AbstractThis article presents a sign- and usage-based model of intentionality following the works of Robert B. Brandom and T. L. Short. The concept of discursive intentionality is established within Brandom’s theory of language explains discursive and practical reasoning as well as attributive and ascriptive practices. Discursive intentionality is distinguished from other intentionalities of conceptual proximity. Because Brandom’s concept of signs is underdetermined in his works, it will be complemented with T. L. Short’s theory of intentional signs. This dual theoretical framework leads to an innovative analysis of verbs which locates discursive intentionality at the semantic/pragmatic interface. After giving a definition of discursive intentionality, it will be diagrammed by breaking it down into different components (relata, relations, and predicates). Finally, it is tested regarding the plausibility of the diagrammatics of discursive intentionality, using the intentional verb “to promise” to differentiate between the ascription of intentionality and intention.
Effect of small amounts of chalcogen alloying elements on the oxidation resistance of copper
Authors: Zhu Yongfu , Wang Yaru , Zhang Jian , Li Chunhe , Ji Zhengtong , Liu Guojun 
Published: November 2020

Abstract
The effect of small amounts of chalcogen alloying elements (S, Se and Te) on the oxidation resistance (OR) of Cu has been investigated at 300–800 °C in 0.1 MPa oxygen atmospheres. Compared to pure copper, the addition of S, Se and Te could effectively improve the OR below 600 °C mainly owing to the chalcogen-element inclusions which hinder the diffusion of Cu. However, it becomes weak above 800 °C. In contrast, the failure at 800 °C is associated with the absence of those inclusions. The results are discussed in detail by the thermodynamic methods.
