The use of convalescent plasma, dexamethasone and remdesivir in a renal transplant patient infected with COVID-19
Authors: Hannabas Sheena , Hannabas Gregory , Pena Camilo
Published: October 2020

Background Immunocompromised patients, such as renal transplant recipients, are a high-risk population for coronavirus disease 2019 (COVID-19) infection and complications. The evidence to support specific treatment of COVID-19 in this group of patients remains very limited. We present the first case in West Texas of a renal transplant patient who received combined therapy with convalescent plasma, dexamethasone, and remdesivir for the treatment of COVID-19.
Case summary We report a female patient who received a deceased donor kidney transplant approximately 2 years prior. She was admitted to our institution with respiratory distress with symptomatic COVID-19 infection. Her baseline renal allograft function per serum creatinine was 0.9 mg/dL, and she was on maintenance immunosuppression with tacrolimus, mycophenolate mofetil, and prednisone. Throughout her hospitalization, her mycophenolate mofetil was maintained, the prednisone was switched for dexamethasone, and her tacrolimus dosage required multiple adjustments secondary to interactions with the azithromycin used to treat an atypical pneumonia upon admission to the hospital. The patient eventually required supplemental oxygen with a venti-mask at 50% FiO2 and transfer to the medical intensive care unit. She received convalescent plasma from a COVID-19 recovered patient, in addition to dexamethasone and then remdesivir for 5 days, with clinical improvement. She was discharged on 3 L per minute supplemental oxygen by nasal cannula from the hospital on day 17 of hospitalization.
Conclusion This renal transplant patient in West Texas with symptomatic COVID-19 infection was treated with convalescent plasma, remdesivir, and dexamethasone with a good outcome. This case also shows the common and often missed drug interactions between tacrolimus and azithromycin and describes a safe way of lowering immunosuppression without compromising renal allograft function.

Perianal Circumferential Reconstruction with Tailored Superior Gluteal Artery Perforator Flap
Authors: Moon Jeehyun , Lee Kyeong Tae
Published: October 2020

Reconstruction following wide excision of perianal lesion is challenging as it requires resistance to high risks of wound contamination and preservation of anal function. Here, we present a case of a unilateral superior gluteal artery perforator (SGAP) flap with an opening in the flap. A 77-year old woman was referred due to an extramammary Pagets disease encircling the anus. Wide excision was performed by the general surgeon team, which generated a circumferential perianal defect. A unilateral SGAP flap was elevated. Primary defatting was done and an opening was made at the proper location of the anus. The anal mucosa was pulled out through the hole and sutured to the flap. She was discharged without any complications. At the follow-up visit, preservation of postoperative anal functions, as well as satisfactory contour, were observed. A well-tailored unilateral SGAP flap may be a good option for reconstruction of a perianal defect encircling the anus.

Supernumerary teeth can develop in any location of the mandible or maxilla and may have a significant impact on the developing dentition. This paper reviews the prevalence, aetiology and classification of supernumerary teeth. It also describes their clinical characteristics and management options. A case report involving the interdisciplinary management of delayed eruption of central incisors due to the presence of a supernumerary tooth is outlined.

CPD/Clinical Relevance: Timely diagnosis and appropriate management may reduce the potential problems associated with supernumerary teeth. General dental practitioners should be aware of the clinical characteristics and management options related to supernumerary teeth.
The Role of Professional Advocate in Endoscopy: The A-Equip Model
Authors: Mahachi Loraine Chenai
Published: October 2020

In endoscopy, quality improvement (QI) is paramount and integral to Joint Advisory Group (JAG) accreditation. The challenge is to keep staff engaged and enthused in the face of factors that influence their emotions and behaviour. This was demonstrated in the author's endoscopy recovery units being used to cope with an inpatient surge for 14 months, which increased stress, sickness and turnover and lowered compliance with clinical audits. The professional advocate (PA) was tasked with addressing this and established that the QI systems in place were inadequate without investment in the team's human and social capital. The PA acted according to the Advocating and Educating for Quality Improvement (A-EQUIP) model to create a positive environment and support continuous improvement using various wellbeing tools and techniques. Restorative clinical supervision, human factors training and concepts from neurological and social sciences were employed to increase self-awareness, improve attitudes and build resilience in the workforce. These techniques have received positive feedback and become integral to the service. Endoscopy services should prioritise investment in workforce education and wellbeing and adopt the role of PA, which should be considered as part of JAG workforce standards.
Mesenchymal stem cells - a promising strategy for treating knee osteoarthritis
Authors: Wang Jiaqian , Zhou Liang , Zhang Yong , Huang Lixin , Shi Qin
Published: October 2020

Aims

The purpose of our study was to determine whether mesenchymal stem cells (MSCs) are an effective and safe therapeutic agent for the treatment of knee osteoarthritis (OA), owing to their cartilage regeneration potential.

Methods

We searched PubMed, Embase, and the Cochrane Library, with keywords including “knee osteoarthritis” and “mesenchymal stem cells”, up to June 2019. We selected randomized controlled trials (RCTs) that explored the use of MSCs to treat knee OA. The visual analogue scale (VAS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), adverse events, and the whole-organ MRI score (WORMS) were used as the primary evaluation tools in the studies. Our meta-analysis included a subgroup analysis of cell dose and cell source.

Results

Seven trials evaluating 256 patients were included in the meta-analysis. MSC treatment significantly improved the VAS (mean difference (MD), –13.24; 95% confidence intervals (CIs) –23.28 to –3.20, p = 0.010) and WOMAC (MD, –7.22; 95% CI –12.97 to –1.47, p = 0.010). The low-dose group with less than 30 million cells showed lower p-values for both the VAS and WOMAC. Adipose and umbilical cord–derived stem cells also had lower p-values for pain scores than those derived from bone marrow.

Conclusion

Overall, MSC-based cell therapy is a relatively safe treatment that holds great potential for OA, evidenced by a positive effect on pain and knee function. Using low-dose (25 million) and adipose-derived stem cells is likely to achieve better results, but further research is needed. Cite this article: Bone Joint Res 2020;9(10):719–728.

Authors: Yadav S. K. , Baghel Shanya , Saxena Sugandha , Singh Avinash Kumar
Published: October 2020

The idea of the present paper is the use of the known information on study variable for enhanced estimation of average paddy production of Pira Nagar village at Barabanki District in India under the Simple Random Sampling Scheme. This known information is utilzed in the form of median of primary variable as it is readily available and does not require every unit of the population to be inquired. The Bias and MSE of the suggested estimator are derived up to approximation of degree one.The minimum value of the MSE of suggested estimator is also obtained by optimizing the characterizing scalar. The MSE has also been compared with the considered competing estimators both theoretically and empirically. The theoretical efficiency conditions of the suggested estimator to be better than the considered estimators are verified using natural population on primary data collected from Pira Nagar Village at Barabanki District of Uttar Pradesh state in India.

High-quality holographic stereogram generation using four RGBD images
Authors: Fachada Sarah , Bonatto Daniele , Lafruit Gauthier
Published: October 2020

To computer-generate high-quality holographic stereograms, a huge number of images must be provided: several hundred for a horizontal parallax and the square of this number for a full parallax. In this paper, we propose to drastically reduce this number to four input images with depth maps (or equivalently, four groups of neighboring images used to compute a depth map) in any pose, in order to create the missing images with depth image-based rendering. We evaluate the view synthesis method objectively before providing visual results of the corresponding holographic stereograms. We believe this method outperforms shearlet-based approaches in objective view synthesis quality metrics and in the number of required input images (7×7).
Using the Gouy phase anomaly to localize and track bacteria in digital holographic microscopy 4D images
Authors: Gibson True , Bedrossian Manuel , Serabyn Eugene , Lindensmith Chris , Nadeau Jay L.
Published: October 2020

Described over 100 years ago, the Gouy phase anomaly refers to the
additional

π

phase shift that is accumulated as a
wave passes through focus. It is potentially useful in analyzing any
type of phase-sensitive imaging; in light microscopy, digital
holographic microscopy (DHM) provides phase information in the encoded
hologram. One limitation of DHM is the weak contrast generated by many
biological cells, especially unpigmented bacteria. We demonstrate here
that the Gouy phase anomaly may be detected directly in the phase
image using the z-derivative of the phase, allowing for precise
localization of unlabeled, micrometer-sized bacteria. The use of dyes
that increase phase contrast does not improve detectability. This
approach is less computationally intensive than other procedures such
as deconvolution and is relatively insensitive to reconstruction
parameters. The software is implemented in an open-source FIJI
plug-in.

Published: October 2020

Subwavelength grating (SWG) waveguides have been shown to provide enhanced light-matter interaction resulting in superior sensitivity in integrated photonics sensors. Narrowband integrated optical filters can be made by combining SWG waveguides with evanescently coupled Bragg gratings. In this paper, we assess the sensing capabilities of this novel filtering component with rigorous electromagnetic simulations. Our design is optimized for an operating wavelength of 1310 nm to benefit from lower water absorption and achieve narrower bandwidths than at the conventional wavelength of 1550 nm. Results show that the sensor achieves a sensitivity of 507 nm/RIU and a quality factor of 4.9 × 104, over a large dynamic range circumventing the free spectral range limit of conventional devices. Furthermore, the intrinsic limit of detection, 5.1 × 10−5 RIU constitutes a 10-fold enhancement compared to state-of-the-art resonant waveguide sensors.
LED primary selection algorithms for simulation of CIE standard illuminants
Authors: Nahavandi Alireza Mahmoudi , Safi Mahdi , Ojaghi Pouya , Hardeberg Jon Yngve
Published: October 2020

Although mixture of LEDs is being considered as a simulator of the CIE daylight series, the performance of the simulations is highly dependent on the SPD of the selected LEDs. An algorithm for selection of the best LEDs for simulation of the CIE daylight series is helpful in this regard. To address this problem, using 200 imaginary light primaries and 40 real LEDs, three algorithms based on concepts of equally spacing of wavelength range (“Equal”), Gram Schmidt orthogonalization in LEDs/light primaries spectral subspace (“Gram”) and the generalization of Gram Schmidt orthogonalization in the LEDs/light primaries projections onto the illuminants subspace (“Ortho”) were proposed and studied. Algorithms, in simulation and reality, were implemented for the CIE standard illuminants of D50, D55, D65 and D75, C and A. The results showed that the performance of the proposed algorithms generally increase with the higher number of selected LEDs/light primaries, while for the LEDs “Gram” and “Ortho” methods showed superior performance, simulations on the imaginary light primaries showed “Ortho” could be considered as the best algorithm.

We use low-resolution optical lithography joined with solid state dewetting of crystalline, ultra-thin silicon on insulator (c-UT-SOI) to form monocrystalline, atomically smooth, silicon-based Mie resonators in well-controlled large periodic arrays. The dewetted islands have a typical size in the 100 nm range, about one order of magnitude smaller than the etching resolution. Exploiting a 2 µm thick SiO2 layer separating the islands and the underlying bulk silicon wafer, we combine the resonant modes of the antennas with the etalon effect. This approach sets the resonance spectral position and improves the structural colorization and the contrast between scattering maxima and minima of individual resonant antennas. Our results demonstrate that templated dewetting enables the formation of defect-free, faceted islands that are much smaller than the nominal etching resolution and that an appropriate engineering of the substrate improves their scattering properties. These results are relevant to applications in spectral filtering, structural color and beam steering with all-dielectric photonic devices.
Constructing ultra-sensitive dual-mode optical thermometers: Utilizing FIR of Mn4+/Eu3+ and lifetime of Mn4+ based on double perovskite tellurite phosphor

Published: October 2020

A strategy of optical temperature sensing was developed by using various thermal quenching of Mn4+ and Eu3+ for double perovskite tellurite phosphor in optical thermometers. Herein, SrGdLiTeO6 (SGLT): Mn4+,Eu3+ phosphors were synthesized by a high-temperature solid-state reaction method. The temperature-dependent emission spectra indicated that two distinguishable emission peaks originated from Eu3+ and Mn4+ exhibited signiﬁcantly diverse temperature responses. Therefore, optical thermometers with a dual-mode mechanism were designed by employing a fluorescence intensity ratio (FIR) of Mn4+ (2Eg→4A2g) and Eu3+ (5D0→7F1,2) and the decay lifetime of Mn4+ as the temperature readouts. The temperature sensing of the phosphors ranging from 300 to 550 K were studied. The maximum relative sensitivities (Sr) are obtained as 4.9% K−1 at 550 K. Meanwhile, the 695 nm emission of Mn4+ possessed a temperature-dependent decay lifetime with Sr of 0.229% K−1 at 573 K. Relevant results demonstrate the SrGdLiTeO6:Mn4+, Eu3+ phosphor as an optical thermometer candidate and also provide constructive suggestions and guidance for constructing high-sensitivity dual-mode optical thermometers.
Storage and retrieval of ultraslow soliton at optical nanofiber interface via electromagnetically induced transparency
Authors: Zhou Yong , Yi Can , Liu Qi , Wang Chuan-Kui , Tan Chaohua
Published: October 2020

We theoretically investigate the optical memory in a nanofiber system via electromagnetically induced transparency (EIT) in a nonlinear region. Because of the tight transverse confinement, the light-atom interaction is significantly enhanced and thus, the EIT effect is enhanced. The inhomogeneous mode field distribution contributes spatially to the EIT dispersion. We develop a systematic analysis method to study the nonlinearity of the system and prove that the optical soliton is available in the system and can be stored and retrieved with high efficiency and stability. We also study a strategy to optimize the soliton optical memory. The results obtained in this study are promising for practical applications of all-optical information processing.
Compact full-color holographic 3-D display based on undersampled computer-generated holograms and oblique projection imaging
Authors: Cao Hong-Kun , Hwang Yong-Seok , Kim Eun-Soo , Jin Xin
Published: October 2020

A compact full-color electro-holographic three-dimensional (3-D) display with undersampled computer-generated holograms (US-CGHs) and oblique projection imaging (OPI) is proposed. For its realization, undersampling conditions of the CGH enabling the complete recovery of image information are derived, and the OPI-based longitudinal-to-lateral depth conversion (LTL-DC) scheme allowing the simple reconstruction of full-color images is also proposed. Three-color off-axis US-CGHs are generated with their center-shifted principle fringe patterns (CS-PFPs) of the novel look-up table (NLUT) method, where center-shifts are calculated with the derived undersampling conditions of the CGH based on the generalized sampling theorem, and then multiplexed into the color-multiplexed hologram (CMH). The CMH is loaded on a SLM (spatial light modulator) and reconstructed by being illuminated with a multi-wavelength light source, where an original full-color image is reconstructed being spatially separated from the other color-dispersed images on the projected image plane with the OPI-based LTL-DC process, which enables us to view the original full-color image just with a simple filter mask. Performance analysis and successful experiments with the test 3-D objects in motion confirm the feasibility of the proposed system.
Zero-guard band dual-SSB PAM4 signal transmission with joint equalization scheme
Authors: Li Jingchi , An Shaohua , Su Yikai
Published: October 2020

We propose and experimentally demonstrate a joint equalization scheme to recover a zero-guard band dual-single sideband (dual-SSB) four-level pulse amplitude modulation (PAM4) signal in a system with moderate bandwidth limitation. In the joint equalization scheme, a multiple-input multiple-output feedforward equalizer (MIMO-FFE) is first used to mitigate the residual crosstalk resulting from non-ideal optical filtering. Then, a modified post filter (PF) is placed after the MIMO-FFE to suppress the MIMO-FFE-enhanced low-frequency noise, whereas the known inter-symbol interference introduced by the modified PF is further eliminated with the maximum likelihood sequence estimation algorithm. Based on the proposed scheme, we experimentally demonstrate a 112-Gb/s zero-guard band dual-SSB PAM4 signal transmission over an 80-km single mode fiber with the averaged bit error ratio of two sidebands below

Entraining neurons via noninvasive electric stimulation improves cognition
Authors: van der Plas Mircea , Hanslmayr Simon
Published: October 2020

Transcranial Alternating Current Stimulation (tACS) is a method that injects rhythmic currents into the human brain via electrodes attached to the scalp of a participant. This technique allows researchers to control naturally occurring brain rhythms and study their causal relevance for cognition. Recent findings, however, cast doubts on the effectiveness of tACS to stimulate the brain and its mode of action. Two new studies by Vieira and colleagues and Marchesotti and colleagues reported in the current issue report promising new results in showing that tACS can entrain single neuron activity and improve reading abilities in dyslexic individuals.
T is for territory: Gathering data about human experience in Developmental Transformations and advancing technologies
Authors: Marshall Jennifer
Published: October 2020

This article makes a comparison between developing technologies in the field of artificial intelligence (AI) and a practice used by drama therapists called Developmental Transformations (DvT). Both technologies gather granular data on human bodies; however, AI does so in the virtual realm, whereas DvT necessitates a physical encounter. As a contribution to theory, this article raises questions about whether interactions with technological interfaces are actual, virtual or somewhere in-between, and about where our bodies intersect in that dimensional landscape. Is it possible for practitioners of drama therapy, specifically DvT, to be in conversation with the growing dominance of technologies operated through AI, and where do the boundaries of human territory fit in relation to both? The relationship between these two approaches to data gathering are explored through the use of arts-based research in the form of collage. Possible implications for future practice as research are considered.
The ‘gambling turn’ in digital game monetization
Authors: Johnson Mark R. , Brock Tom
Published: October 2020

This article examines how ‘gambling’ secured a central economic and cultural position in the development of modern digital games. We first trace how developers have monetized ‘games’ and ‘play’, from slot machines to PC, console and mobile platforms, before considering the recent controversy over ‘loot boxes’ as an emblematic case study of the ongoing gamblification of digital play. We argue that (1) the rising costs of development and marketing for ‘blockbuster’ games, (2) an overcrowded marketplace and (3) significant shifts in the corporate culture of the games industry are creating cultural conditions which legitimize gambling as a form of digital game production and consumption. This is evidenced in developers’ capacity to innovate around legal challenges and player demand for further customization and rewards. What emerges is a question about the future direction of game development and the impact of a logic of money, rather than play, which now underwrites it.

Published: October 2020

Em 2020, os debates correntes e académicos sobre o jornalismo nos Estados Unidos - e nos países em que foi significativamente influenciado pelo modelo norte-americano - assumiram que a “objetividade” é o ideal que orienta a atividade do jornalista. Mas essa assunção carece de fundamentação. No trabalho conjunto com Katherine Fink (2004), defendi que nos Estados Unidos ocorreu uma transformação dramática nas práticas e ideais jornalísticos, que teve início no final dos anos 60 e que se consolidou a partir da década de 1970. Se nos anos 50 e 60 o modelo da “objetividade” é aplicável a cerca de 90% das notícias de primeira página dos principais jornais norte-americanos, no final dos anos 70 adequa-se a apenas 40-50% das notícias, sendo que as restantes peças remetem para o chamado jornalismo “contextual” ou “analítico”. Outros autores chegam à mesma conclusão no que concerne ao jornalismo norte-americano e outros ainda encontram mudanças similares em vários países da Europa. Por que razão jornalistas e historiadores do jornalismo não identificaram esta mudança? De que forma podemos compreender melhor esta transformação no âmbito do profissionalismo moderno, de um Profissionalismo 1.0 para um Profissionalismo 2.0 - uma revolução poderosa que foi anterior à revolução digital? Este ensaio procura dar resposta a estas questões.

The purposes of this study were to evaluate the impact of Ranggeh river riparian rehabilitation and to determine environmental parameters that influenced benthic macroinvertebrate communities in Ranggeh River. This research was conductedfrom February to September 2019. Benthic macroinvertebrate Benthic macroinvertebrates, river, evaluation, EPT, rehabilitationsamples were collected using Hess Sampler in a sampling area of 0.2 m2. This evaluation was carried out after two months since the rehabilitation of riparian habitat completed. The results show that rehabilitation of the riparian habitat has changed the community, in the aspects of biological metrics of taxa number, abundance, and taxa numbersof Ephemeroptera, Plecoptera, and Trichoptera (EPT). Furthermore, the taxa number and EPT metrics increased after habitat rehabilitation, however the abundance decreased slightly. In addition, the taxa number metric was positively correlated with conductivity parameter (r = 0.8), but negatively correlatedto turbidity (r = -0.91) and pH (r = -0.77). Meanwhile, the EPT metric was negatively correlated with turbidity parameters (r = -0.76) and  %embeddedness (r = -0.94). The total abundance metric was not sensitive to the parameters measured in this study. Meanwhile, biological metrics for taxa number and EPT can be used to assess rehabilitation success of river ecosystem habitats
Public Preferences and Predicted Uptake for Esophageal Cancer Screening Strategies: A Labeled Discrete Choice Experiment
Authors: Peters Yonne , Siersema Peter D.
Published: October 2020

INTRODUCTION:

As novel, less invasive (non)endoscopic techniques for detection of Barrett's esophagus (BE) have been developed, there is now renewed interest in screening for BE and related neoplasia. We aimed to determine public preferences for esophageal adenocarcinoma screening to understand the potential of minimally invasive screening modalities.

METHODS:

A discrete choice experiment was conducted in 1,500 individuals, aged 50–75 years, from the general population. Individuals were repeatedly asked to choose between screening scenarios based on conventional upper endoscopy, transnasal endoscopy, nonendoscopic cell collection devices, breath analysis, and a blood test, combined with various levels of test sensitivity and specificity, and no screening. A multinomial logit model was used to estimate individuals' preferences and to calculate expected participation rates.

RESULTS:

In total, 554 respondents (36.9%) completed the survey. The average predicted uptake was 70.5% (95% confidence interval: 69.1%–71.8%). Test sensitivity (47.7%), screening technique (32.6%), and specificity (19.7%) affected screening participation (all P < 0.05). A low test sensitivity had the highest impact on screening participation, resulting in a 25.0% (95% confidence interval: 22.6%–27.7%) decrease. Respondents preferred noninvasive screening tests over endoscopic and capsule-based techniques, but only if sensitivity and specificity were above 80%.

DISCUSSION:

Our study suggests that individuals generally prefer noninvasive BE screening tests. However, these tests would unlikely improve screening uptake when associated with a much lower accuracy for detecting BE and esophageal adenocarcinoma compared with conventional upper endoscopy. Improving accuracy of minimally invasive screening strategies and informing the target population about these accuracies is therefore essential to maximally stimulate screening participation.

Tomando como punto de partida la tragedia griega, que a su manera da cuenta de acontecimientos históricos, se hace una aproximación al teatro y a la historia en Colombia y en América Latina. Teatro e historia, historia y teatro son para el autor dos dimensiones que se cruzan, se repiten, se convocan y se citan, de ahí las distintas formas del teatro político. Tanto el teatro como la historia dan cuenta de las cruentas luchas por el poder, en medio de las cuales la historia se convierte, muchas veces, en un gran decorado, sobre cuyo fondo nos corresponde indagar el tipo de personaje histórico-teatral que estamos conminados a representar.
A proposed method for handling an imbalance data in classification of blood type based on Myers-Briggs type indicator
Authors: Akbar Ahmad Taufiq , Husaini Rochmat , Akbar Bagus Muhammad , Saifullah Shoffan
Published: October 2020

Blood type still leads to an assumption about its relation to some personality aspects. This study observes preprocessing methods for improving the classification accuracy of MBTI data to determine blood type. The training and testing data use 250 data from the MBTI questionnaire answers given by 250 respondents. The classification uses the k-Nearest Neighbor (k-NN) algorithm. Without preprocessing, k-NN results in about 32 % accuracy, so it needs some preprocessing to handle data imbalance before the classification. The proposed preprocessing consists of two-stage, the first stage is the unsupervised resample, and the second is the supervised resample. For the validation, it uses ten cross-validations. The result of k-Nearest Neighbor classification after using these proposed preprocessing stages has finally increased the accuracy, F-score, and recall significantly.

Authors: Kao Ching-Kuei
Published: October 2020

In today’s society with a globalized economy, countries around the world are pursuing efficiency while also pursuing environmentally sustainable development. Therefore, studying green coal logistics for environmental development and optimization is of great significance and practical value. On the basis of the green concept framework of coal logistics, this paper will determine the five main problems in the operation of green coal logistics and then propose seven improvement strategies to these five main problems by using TRIZ theory. Interpretative structural modeling (ISM) is used to establish a systematic development procedure of green coal logistics strategy to examine the development of green coal logistics. The analysis results of ISM indicate that, when developing green coal logistics, coal enterprises should retain the effective operation of the original operating mechanism. At the same time, enterprises should introduce a green coal logistics system and effectively merge the two to establish a simple and effective logistics system operating mechanism and cultivate employees’ awareness of environmental protection. Doing so will establish a green image of coal enterprises and decrease the cost of green logistics of coal enterprises. Next, each department within the coal enterprise should be refined. To enable various departments within the coal enterprise to improve work efficiency through information sharing and exchange, the operation process of each department needs to be standardized and the source and the scope of information of each department must be clarified. Finally, through the production, storage, sharing, and transfer of knowledge of information, coal enterprise employees can be assisted to effectively carry out green awareness popularization courses so they can acquire, produce, store, share, and transfer the knowledge of green coal logistics to enable coal enterprises and employees to understand the relationship between the development of green coal logistics and environmental protection.

Published: October 2020

Many South African roads experience inadequate construction and maintenance. The road construction scantiness is evidenced by the Moloto Road, Gauteng, Mpumalanga and Limpopo. This was dubbed the “notorious road” for the high number of fatal accidents. An assessment of factors influencing the appointment of service providers might be a profound strategy to ensure efficiency and effectiveness in the construction and maintenance of South African roads. The factors under study included financial stability and resources indicators, quality, environmental and safety indicators, management ability, technical capacity and past experience and performance in appointing service providers.

This study sought to determine the importance and influence of the factors affecting the successful appointment of service providers within the Gauteng Department of Roads and Transport.

A quantitative descriptive approach, with the use of a structured questionnaire was utilised to collect data from a sample of 155 employees of Gauteng Department of Roads and Transport within the City of Tshwane. Descriptive and multivariate analyses including factor correlations and regression analyses were conducted.

Some important factors identified when choosing service providers were financial stability and resources indicators, quality, environmental and safety indicators, management ability and experience and performance. Technical capacity was found to be less important. A significant positive relationship was found between factors for choosing service providers and the selection of competent service providers.

The results of this study greatly corresponded with the literature review. The same factors were identified as influencing the successful appointment of service providers in this department.
ANT and Engineering Education, learning spaces with actors
Authors: Figueiredo Jose
Published: October 2020

Engineering education is a situated process, enacted by empowerment, motivation and enrolment of actors, using different materials, and framed in exploratory attempts. Inscribing technologic design in the use of artefacts is a basic engineering concern and pushes us to sociotechnical ambiences of value earning and sustainability. We think Actor-Network Theory provides a framework that contributes to our understanding of complexity inscribed in the relations and mutual influences that emerge among actors in learning spaces. Using narrative, and exploring ANT concepts, we circulate in learning spaces, observing and deciding about ways we can explore to enhance knowledge creation and learning. Our results are exploratory but they intend to contribute to a different look into educational fields. Our basic goal is to convince researchers to join us in our reflections and experiments. We believe we are tackling with an innovative perspective, consistent with an extension to this area of knowledge – engineering education.
