Communication and media studies in South Africa: Observations, impressions and remarks

Field: Social Sciences (Social Sciences)

Abstract This article offers some self-reflexive comments on Communication and media studies in South Africa. The discipline in South Africa, presents a very exciting and intriguing posture for the simple fact that it allows for diversity– observable in the variety of labels, emphases and curricula. Equally enviable is the currency of some aspects of the programmes offered in the country and the strong theoretical foundation of research publications. Yet some deficiencies observed in a number of the curricula provoke a call for standardization of programmes offered by the various universities. The lack of regulation could be held responsible for some lapses noticeable in the structure of the various programmes. Drawing on observations of South Africa’s communication and media education landscape, this article argues that the field seems to be withdrawn and too inward-looking that is evidenced by the lack of interest in the affairs of the African Council for Communication Education (ACCE) and what used to be the predominantly locally oriented content of South African journals. Thus, South African academia is tactically excluded from the leadership which it should provide on the African continent. Some cross-references are made to the situation in Nigeria, being the country where the writer had been involved in communication and media scholarship before moving to South Africa.

Involvement of PI3K, Akt and RhoA in Oestradiol Regulation of Cardiac iNOS Expression

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Background: Oestradiol is an important regulatory factor with several positive effects on the cardiovascular (CV) system. We evaluated the molecular mechanism of the in vivo effects of oestradiol on the regulation of cardiac inducible nitric oxide (NO) synthase (iNOS) expression and activity. </P><P> Methods: Male Wistar rats were treated with oestradiol (40 mg/kg, intraperitoneally) and after 24 h the animals were sacrificed. The concentrations of NO and L-Arginine (L-Arg) were determined spectrophotometrically. For protein expressions of iNOS, p65 subunit of nuclear factor-κB (NFκB-p65), Ras homolog gene family-member A (RhoA), angiotensin II receptor type 1 (AT1R), insulin receptor substrate 1 (IRS-1), p85, p110 and protein kinase B (Akt), Western blot method was used. Coimmunoprecipitation was used for measuring the association of IRS-1 with the p85 subunit of phosphatidylinositol- 3-kinase (PI3K). The expression of iNOS messenger ribonucleic acid (mRNA) was measured with the quantitative real-time polymerase chain reaction (qRT-PCR). Immunohistochemical analysis of the tissue was used to detect localization and expression of iNOS in heart tissue. </P><P> Results: Oestradiol treatment reduced L-Arg concentration (p<0.01), iNOS mRNA (p<0.01) and protein (p<0.001) expression, level of RhoA (p<0.05) and AT1R (p<0.001) protein. In contrast, plasma NO (p<0.05), Akt phosphorylation at Thr308 (p<0.05) and protein level of p85 (p<0.001) increased after oestradiol treatment. </P><P> Conclusion: Our results suggest that oestradiol in vivo regulates cardiac iNOS expression via the PI3K/Akt signaling pathway, through attenuation of RhoA and AT1R.
Characterization and comparison of antimicrobial susceptibilities and outer membrane protein and plasmid DNA profiles of Pasteurella haemolytica and certain other members of the genus Pasteurella

Field: Immunology and Microbiology (Life Sciences)

SUMMARY The outer membrane protein ( omp ), plasmid, and antimicrobial resistance profiles of Pasteurella haemolytica serotypes 1 through 12, a bovine isolate of P multocida , a chicken isolate of P multocida , and an unidentified Pasteurella species of bovine origin were examined. Isolates of P haemolytica serotypes belonging to the same biotype possessed similar omp profiles. Biotype A isolates contained 2 prominent omp of 43 kilodaltons (kD) and 29 kD, whereas biotype-T serotypes contained 3 major omp of 43, 36, and 25 kD. The major omp profiles of the 2 P multocida isolates and the unidentified Pasteurella species were different from each other and from P haemolytica isolates. Plasmid dna screening indicated both plasmid-containing and plasmid-free P haemolytica and P multocida isolates. Multiple drug resistance was found in pasteurellae isolates with and without plasmids. However, a relationship between drug resistance and plasmid isolation was found in 3 of 4 P haemolytica serotype 1 field isolates, all of which contained a 2.51-megadalton plasmid and had multiple drug resistance for benzylpenicillin, ampicillin, streptomycin, and tetracycline.

MEASUREMENT OF SURFACE CONDENSATION BY MULTI-SPECTRAL SCANNER : Correspondence between MSS data and weight of condensation liquid water

Field: Engineering (Physical Sciences)

The authors work out the method that surface condensation of wall is measured by using Multi-Spectral Scanner(MSS), and experiments concerned are conducted on aluminum boards. The results are summarized as follows : (1) It was clarified that the data of spectral radiance acquired by MSS decline in infrared regions, especially at 1500nm and 2000nm, as surface condensation goes on. (2) Progressing degree of surface condensation was expressed by radiant intensity ratios, such as 1600nm/1500nm and 2100nm/2000nm. (3) Correspondence between spectral radiance ratio of 1600nm/1500nm and weight of condensation liquid water was analysed.
Predictors of Postdischarge Outcomes From Information Acquired Shortly After Admission for Acute Heart Failure

Field: Medicine (Health Sciences)

Background— Acute heart failure is a common reason for admission, and outcome is often poor. Improved prognostic risk stratification may assist in the design of future trials and in patient management. Using data from a large randomized trial, we explored the prognostic value of clinical variables, measured at hospital admission for acute heart failure, to determine whether a few selected variables were inferior to an extended data set. Methods and Results— The prognostic model included 37 clinical characteristics collected at baseline in PROTECT, a study comparing rolofylline and placebo in 2033 patients admitted with acute heart failure. Prespecified outcomes at 30 days were death or rehospitalization for any reason; death or rehospitalization for cardiovascular or renal reasons; and, at both 30 and 180 days, all-cause mortality. No variable had a c-index >0.70, and few had values >0.60; c-indices were lower for composite outcomes than for mortality. Blood urea was generally the strongest single predictor. Eighteen variables contributed independent prognostic information, but a reduced model using only 8 items (age, previous heart failure hospitalization, peripheral edema, systolic blood pressure, serum sodium, urea, creatinine, and albumin) performed similarly. For prediction of all-cause mortality at 180 days, the model c-index using all variables was 0.72 and for the simplified model, also 0.72. Conclusions— A few simple clinical variables measured on admission in patients with acute heart failure predict a variety of adverse outcomes with accuracy similar to more complex models. However, predictive models were of only moderate accuracy, especially for outcomes that included nonfatal events. Better methods of risk stratification are required.

Evaluation of Correlation of Cell Cycle Proteins and Ki-67 Interaction in Paranasal Sinus Inverted Papilloma Prognosis and Squamous Cell Carcinoma Transformation

Field: Medicine (Health Sciences)

The recurrent sinonasal inverted papilloma (IP) could be transformed to sinonasal squamous cell carcinoma. We use protein expression patterns by immunohistochemical method to see whether the expression of p53, p16, p21, and p27 belongs to cell-cycle-regulators and PCNA (proliferating cell nuclear antigen) and Ki-67 the proliferation markers in sixty patients with sinonasal inverted papilloma, and 10 of them with squamous cell carcinoma transformation. Significantly elevated levels of Ki-67, p27, and PCNA in IP with squamous cell carcinoma transformation of sinonasal tract compared with inverted papilloma were revealed. No variation of p16, p21, PLUNC (palate, lung, and nasal epithelium clone protein) and p53 expression was correlated to sinonasal IP malignant transformation by multivariate survey. However, we found elevated PLUNC expression in IPs with multiple recurrences. Finally, we found that PCNA, p27 may interact with CDK1 which promote IP cell proliferation and correlate to sinonasal squamous cell carcinoma. Ki-67 could work throughout the cell cycles to cause malignant transformation. In conclusion, this is a first study showing the correlation of Ki-67, PCNA interacted with CDK1 might lead to malignant transformation. Elevated PLUNC expression in the sinonasal IPs was related to multiple recurrences in human.
Lærerutdannerens digitale kompetanse

Field: Social Sciences (Social Sciences)

This case study focuses on how three teacher educators attempt to enhance their digital competence by participating in the project “Teach As We Preach (TAWP)”. At a policy level in Norway, high priority is given to information and communication technology (ICT) through the new educational reform (Læreplan for Kunnskapsløftet [LK06]). The ICT density is high in school, with one laptop per student considered desirable - a goal that is accomplished in upper secondary school. The main obstacle, however, seems to be the lack of digital competence among both pre-service and in-service teachers. However, the new White Paper No. 11 enhances digital competence to the fifth basic competence in teacher education. The study aims to enhance our understanding of how teacher educators’ develop their digital competence as part of their digital didactics and the research question is: How can students’ feedback in- and after plenary lectures contribute to enhance teacher educator’s digital competence? The empirical analysis shows that the informants, despite thresholds and challenges, find the strategy applied in this project constructive with regards to their professional development within the field of digital competence.
Collective memory, the news media, and Major League Baseball's Steroid Era

Field: Social Sciences (Social Sciences)

News journalists are charged with documenting current events in an objective manner. As a by-product of this role, journalistic accounts are often seen outside of the cultural realm, as third-party reports that are free from personal bias or cultural influences. There is a growing body of scholarship that refutes this categorization, arguing that journalism is distinctly inside the cultural realm and necessarily influenced by societal factors. This study draws on collective memory theory, and seeks to understand how the collective memory of Major League Baseball's history influenced journalistic accounts of baseball's Steroid Era from the late 1990s up to the year 2013. Utilizing a grounded theory methodology, this study qualitatively analyzed 226 news articles from both national and local newspapers and sports magazines in the years 1998, 2002, 2004, 2007, and 2013. The researcher identified articles' narrative structures and transformations of collective memories over time. Both of these aspects were then measured against the study's stated goal of objectivity, which was to "to "reach the highest degree of correspondence between journalistic assertions and reality" (Boudana, 2011, p. 396). The study found that the historical values with which the baseball collective identified--namely, that baseball had historically been a game of integrity--strongly influenced media coverage of the scandal. The partiality of collective memory negatively affected journalistic objectivity, as journalists often compared the current era to inherently incomplete versions of the past.
Expression of the neu protooncogene in the mammary epithelium of transgenic mice induces metastatic disease.

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Overexpression and amplification of the neu (c-erbB2, ERBB2) protooncogene have been implicated in the development of aggressive human breast cancer. To directly assess the effect of mammary gland-specific expression of the neu protooncogene, transgenic mice carrying unactivated neu under the transcriptional control of the mouse mammary tumor virus promoter/enhancer were established. By contrast to the rapid tumor progression observed in several transgenic strains carrying the activated neu transgene, expression of unactivated neu in the mammary epithelium resulted in the development of focal mammary tumors after long latency. The majority of the mammary tumors analyzed expressed elevated levels of neu-encoded mRNA and protein. Overexpression of neu in the mammary tumors was also associated with elevated neu intrinsic tyrosine kinase activity and the de novo tyrosine phosphorylation of several cellular proteins. Interestingly, many of the tumor-bearing transgenic mice developed secondary metastatic tumors in the lung. These observations suggest that overexpression of the unactivated neu protein can induce metastatic disease after long latency.
Investigation of the efficiency of non-toxic RbGeX3 (X = I, Br, Cl) perovskites as absorption layer in solar energy converters based on thickness dependency

Field: Materials Science (Physical Sciences)

Abstract To promote green environmental protection, we explore Ge-based perovskites i.e., RbGeX 3 (X= I, Br, or Cl) as alternatives to Pb-based perovskites for efficient solar cells. Their properties are analyzed using density functional theory (DFT). The phonon dispersion curve and cohesive energies are utilized to determine the dynamic stability of RbGeX 3 perovskite materials. The mechanical stability was validated through Born stability criteria, while thermodynamic stability was confirmed despite the lower entropy and large specific heat capacity. The direct bandgaps of the perovskites RbGeI 3 , RbGeBr 3 , and RbGeCl 3 are located at R-point and indicate their semiconducting nature at 0.49 eV, 0.65 eV, and 0.87 eV, respectively. We performed Boltzmann transport calculations to explore the thermoelectric properties of these compounds. Our observations of the high Seebeck coefficients and power factors of these materials indicate their suitability as excellent candidates for thermoelectric device applications. The RbGeI 3 exhibits an impressive static dielectric constant value indicating the material’s property of possessing low carrier recombination. The absorption coefficients of RbGeX 3 depict a red shift while moving in the direction Cl→Br→I. We examined how the substitution of various halogen atoms in RbGeX 3 materials impacts their electronic, optical, thermodynamic, and thermoelectric properties. Based on their thickness, we have employed a spectroscopic limited maximum efficiency (SLME) to predict the solar cell parameters for each perovskite used as an absorber layer. Using the SLME approach, the efficiencies of the RbGeI 3 , RbGeBr 3 , and RbGeCl 3 absorber layers at a thickness of 1 μm are approximately shown 15.67%, 22.08%, and 28.93%, respectively.
Scaling Laws vs Model Architectures: How does Inductive Bias Influence Scaling?

Field: Computer Science (Physical Sciences)

There have been a lot of interest in the scaling properties of Transformer models. However, not much has been done on the front of investigating the effect of scaling properties of different inductive biases and model architectures. Do model architectures scale differently? If so, how does inductive bias affect scaling behaviour? How does this influence upstream (pretraining) and downstream (transfer)? This paper conducts a systematic study of scaling behaviour of ten diverse model architectures such as Transformers, Switch Transformers, Universal Transformers, Dynamic convolutions, Performers, and recently proposed MLP-Mixers. Via extensive experiments, we show that (1) architecture is an indeed an important consideration when performing scaling and (2) the best performing model can fluctuate at different scales. We believe that the findings outlined in this work has significant implications to how model architectures are currently evaluated in the community.

Predictors of Customer Loyalty in Business to Business Trading

Field: Business, Management and Accounting (Social Sciences)

The changing world motivates companies to use intermediaries to ensure their distribution channels are efficient and effective. Many firms serve as intermediaries in delivering products and services to other business organizations. This is known as business to business trading. In business to business (B2B) trading the company becomes an agent to deliver goods to another company. They resell the product to others without transforming or modifying the products. This research was conducted at Petrucom Sdn Bhd Terengganu, a supply based company who is facing challenges in building long-term relationship with their customers. Most of Petrucom Sdn Bhd customers’ are not repeated customers. Therefore, this paper focuses on the factors that contribute to customer loyalty in Petrucom Sdn Bhd. Among the factors highlighted that may influence customer loyalty are responsiveness, communication, trust and customer satisfaction. The results of the study indicated that the most significant factor influencing customer loyalty is customer satisfaction. Customers will make repeated purchases when they are satisfied with the service or product offered. In conclusion, the company should be focusing on how to ensure customers are satisfied with their services whether its’ good quality, affordable price, minimizing
Guidance in breast-conserving surgery: tumour localizationversusidentification

Field: Medicine (Health Sciences)

In breast-conserving surgery (BCS), the tumour is removed with the goal of preserving as much healthy breast tissue as possible. Breast conservation comes with a risk of positive resection margins, an independent predictor of ipsilateral tumour recurrence, necessitating reoperation1. Contemporary data from the UK Get it Right First Time1 suggest high average reoperation rates of around 19 %. Current tumour localization techniques can only guide surgeons to the tumour epicentre, but fail to provide identification of the boundary between tumour and normal tissue. Imaging techniques, such as intraoperative ultrasonography (IOUS), intraoperative MRI (iMRI) or fluorescence-guided surgery (FGS), enable visualization of the tumour in its entirety and may provide improved operative precision2–5.
A Review on COVID-19 Mediated Impacts and Risk Mitigation Strategies for Dental Health Professionals

Field: Dentistry (Health Sciences)

Abstract In the light of coronavirus disease 2019 (COVID-19), dentistry is facing unprecedented challenges. The closure of clinics has impacted dental health professionals (DHPs) not only financially but also psychologically. In this review, these consequences are discussed in detail to highlight the challenges that DHPs are facing thus far, in both developing and developed nations. Compromised mental health among DHPs is an important area that requires attention during this difficult period. Although, in previous pandemics, dentists have not worked on the frontline, the article discusses how their wide range of skillsets can be leveraged if another wave of COVID-19 pandemic appears. Finally, guidelines to reopen clinics and patient management have been discussed in detail that could serve as a quick reference guide for DHPs.
