LINGUÍSTICA E PUBLICIDADE: UM OLHAR ENUNCIATIVO SOBRE UMA CAMPANHA PUBLICITÁRIA DO CITIBANK.
Authors: Siqueira Ellen Cristina Gerner 
Published: May 2019

O discurso publicitário está presente no cotidiano das pessoas por meio de diversos tipos de mídia: anúncios na TV, impressos, outdoors ou nas redes sociais. Entre os recursos utilizados pela publicidade para convencer as pessoas sobre os produtos, serviços ou ideias que se deseja vender nos interessa estudar o uso da linguagem verbal, mais especificamente a maneira com que a publicidade constrói sentido por meio da linguagem. Assim, este artigo pretende analisar alguns enunciados de uma campanha publicitária realizada pela instituição financeira Citibank sob o olhar da teoria enunciativa desenvolvida por Oswald Ducrot. A campanha serve como exemplo do jogo argumentativo que pode ser criado por meio da linguagem verbal, enredado em si mesmo, onde o locutor não fala sobre o mundo, mas fala para construir o mundo e explicitar a sua verdade por meio de argumentação linguística e não, necessariamente, retórica. Abstract: Advertising speech is present in people's daily lives through various types of media: TV ads, print ads, billboards, or social networks. Among the resources used by advertising to convince people about the products, services or ideas they want to sell we are interested in studying the use of verbal language, more specifically the way in which advertising builds meaning through language. Thus, this article intends to analyze some statements of an advertising campaign carried out by the financial institution Citibank under the view of the enunciative theory developed by Oswald Ducrot. The campaign is a great example of the game of argumentation that can be created through verbal language, entangled in itself, in which the speaker does not speak about the world, but speaks to build the world and to explain its truth through linguistic argumentation and not , necessarily, rhetoric.

Cumulative antimicrobial susceptibility data for a tertiary-level paediatric oncology unit in Johannesburg, South Africa
Authors: Von Knorring Nina , Nana Trusha , Chibabhai Vindana 
Published: May 2019

Background: There is global concern regarding the spread of antimicrobial resistance in bacteria and fungi. Oncology patients are at particular risk of infections with multidrug resistant organisms. These patients require urgent initiation of empiric antimicrobial therapy when presenting with neutropenic fever. Currently, piperacillin-tazobactam and amikacin with or without vancomycin is the treatment of choice in the unit.Aim: The purpose of this study was to develop a cumulative antibiogram for the paediatric oncology unit at Charlotte Maxeke Johannesburg Academic Hospital (CMJAH) to guide empiric treatment recommendations for patients presenting with suspected bacterial or fungal infection.Setting: Tertiary-level paediatric oncology unit.Methods: A retrospective observational analysis was performed of bacterial and fungal antimicrobial susceptibility data extracted from the microbiology laboratory information system for clinical specimens submitted from the paediatric oncology unit at CMJAH. Data was analysed for the period January 2015 to May 2018. In addition, analysis and comparison of two 17-month time periods was performed in order to elicit any changes over time.Results: Klebsiella pneumoniae and Escherichia coli were the most common gram-negative organisms isolated. Twenty-one percent of Enterobacteriaceae showed resistance to third generation cephalosporins and 9% to carbapenems. Rates of carbapenem-resistant isolates decreased significantly over time. Adding amikacin to piperacillin-tazobactam significantly increased bacterial coverage. Coagulase-negative staphylococci and Candida parapsilosis were the most common gram-positive and fungal isolates recovered during the study.Conclusion: The results support the continued use of piperacillin-tazobactam and amikacin for paediatric oncology patients presenting with neutropenic fever in this unit. Antibiograms are an important component of antimicrobial stewardship in conjunction with efficient infection prevention and control measures.
Exploring the characteristic of prophetic-liminality in ministerial leadership: A necessary ethic for contemporary South Africa
Authors: Slater J. 
Published: May 2019

This article explores the prophetic liminality of Christian leadership as it is practiced against the contextual backdrop of social, ecclesial and ethical upheavals such as secularism, relativism, sexism, corruption, violence, crime, women abuse, xenophobia, disbelief and disillusionment in authority both in church and state. It argues for an up-to-date and leading-edge church-ministerial response to modern-day situations. It proposes liminal and innovative leadership for both church and state. However, the liminal quality is specifically aligned with the prophetic dimension of leadership. A prophet's leadership is here understood as visionary leadership that challenges and directs people beyond the ordinary, and confronts that which is unethical in society. Liminal here implies being and functioning at the cutting-edge of events, trailbracing and by steering away from the conventional approaches. Sadly, because leadership had become enmeshed with the systemic designs of the church, society, economics, culture or tribe, it demands to be interjected with an exceptional characteristic to minister both directly and at the same time indirectly to problematic situations. In the words of Diarmud O’Murchu, for a leader to function liminally s/he needs to be on the doorstep or on the horizon of everything contemporary. For leaders to stay in force and relevant implies living with innovative freedom, with human-divine recklessness and with honest integrity. In turn for liminality to be an effective quality in leadership, it involves being spiritually and morally courageous and particularly attuned to a transcendent capacity. This enables the leader to move with the ever changing circumstances of our times, into different situations and cultures, thus devising and applying different responses that constantly accommodate new possibilities The article carves out a theological and a directional itinerary for ministerial leadership that offers a liminal-prophetic liminal–transcendent challenge to leadership today. Liminal transcendent leadership pleads not to be dictated by ecclesial or social conventions and neither by personal conventions. Liminal leadership is by nature a painful search for an appropriate response to what is new, for that which is different in contemporary scenarios.

Authors: Hiremath Roopa , Satyamurthy K.V. , Kulkarni Sanjeev , Jain Arati 
Published: May 2019

Purpose:
This study was done to assess the efficacy of powered endoscopic dacryocystorhinostomy (DCR) with creation of a large bony ostium exposing fundus of the sac and primary mucosal anastomosis.

Methods:
The study involved prospective interventional case series with short perioperative follow up. Operative and postoperative data were prospectively collected on 42 patients (15 men and 27 women; mean age, 62.4 years; range 14–91 years) who presented to a lacrimal clinic with epiphora and obstruction of the nasolacrimal system and who consecutively underwent either primary or revision powered endoscopic DCR. All surgeries were done by the same surgeon by standardized surgical technique. Follow-up evaluation included symptom evaluation and endoscopic assessment of the newly created ostium with fluorescein testing at each postoperative visit.

Results:
The only surgical complication was one case of sub cutaneous emphysema. Thirty nine of the 42 DCRs had anatomically patent naso lacrimal duct after a mean follow-up of 12 months (standard deviation = 5 months), yielding a success rate of 95.7%. Out of three failures, two had closed ostium because of improper use of medications, one patient had granulation tissue at the ostium. Two patients with a patent ostium had functional block and continued to have some symptoms.

Conclusion:
Powered endoscopic DCR with full sac exposure and primary mucosal apposition has a success rate comparable to that achieved with external DCR.

Published: May 2019

Aims: Availability of nutrients-rich topsoil for nursing cocoa seedlings is becoming limited and poor growth of cocoa seedlings in the nurseries has been ascribed to the use of unsuitable potting media. Experiments were conducted to investigate the suitability of compost in improving soil chemical properties and boost the growth of cocoa seedlings at the nursery.
Study Design: The experiment was laid out in a Completely Randomized Design (CRD) with four replications.
Place and Duration of Study: The experiment was carried out at the main nursery of Cocoa Research Institute of Ghana, New Tafo-Akim, between September, 2014 and June 2015.
Methodology: Polybags were filled with soil obtained from an old cocoa plot (K6O2) at Cocoa Research Institute of Ghana. The soil has been classified as Rhodic-Lixic Ferrasol. Three soil: compost mixtures treatments, that is, 90:10, 80:20 and 70:30% w/w were tested. A Standard foliar fertilizer and unamended soil were included as treated and untreated controls. Seedlings were raised from mixed hybrid cocoa and assessed at bi-monthly intervals for six months for growth. Pre and post treatments soil analyses were carried out using standard laboratory procedures.
Results: Initial soil analyses showed that OC (1.18%), Ca (5.60 cmol kg-1), P (14.23 mg kg-1) and pH (5.63) were below the critical values required for good cocoa growth. The 70:30 soil: compost treatment produced significantly (P = .05) tallest plant (41.9 cm) with the unamended control the shortest (30.7 cm) at the end of the study. Residual pH (6.98), OC (2.30%), P (14.23 mg kg-1) and Ca (13.02 cmol kg-1) were significantly (P = .05) higher under the same treatment compared to the unamended control; pH (5.36), OC (1.04%), P (11.65 mg kg-1) and Ca (5.60 cmol kg-1).
Conclusion: Less fertile soils could be improved with the addition of Municipal Solid Waste (MSW) compost for raising good quality cocoa seedlings at the nursery in Ghana.

Published: May 2019

AbstractObjectiveCharcot‐Marie‐Tooth disease (CMT) is a clinically and genetically heterogeneous group of inherited neuropathies. Mutations in more than 90 genes have been implicated in CMT; however, the mutational spectrum of CMT in Chinese population remains obscure. This study aims to provide a comprehensive overview of the frequency of mutations in Taiwanese patients with CMT and look for genotype‐phenotype correlations.MethodsMutational analyses were performed on 427 unrelated Taiwanese patients with CMT by polymorphic microsatellite markers analysis or real‐time fluorescent PCR for PMP22 duplication, Sanger sequencing for GJB1 mutations, and targeted sequencing covering 124 genes causing or relevant to inherited neuropathies. We also correlated the genotypes with the phenotypic features, such as age at disease onset and ulnar motor nerve conduction velocity.ResultsPathogenic mutations were identified in 312 patients (73.1%; 312/427), including 208 patients with a PMP22 duplication, 40 patients with a GJB1 mutation, and 64 patients with a mutation in one of other 18 CMT genes. A confirmed molecular diagnosis was achieved in 84.4% (266/315) of the patients with demyelinating CMT and 41.1% (46/112) of the patients with axonal CMT. Mutations in MPZ, MFN2, or NEFL are the most frequent disease causes in patients with infantile‐onset CMT (≤2 years), while PMP22 duplications and mutations in GJB1, MFN2, or MPZ are the frequent causes among patients with childhood‐ or adolescence‐onset CMT (3–9 years).InterpretationThis study provides a genotype‐phenotype landscape of CMT in Taiwan and highlights the unique spectrum of CMT genes frequencies among patients of Chinese origin.
Zero‐Dimensional Perovskite Nanocrystals for Efficient Luminescent Solar Concentrators

Published: May 2019

AbstractLuminescent solar concentrators (LSCs) are able to efficiently harvest solar energy through large‐area photovoltaic windows, where fluorophores are delicately embedded. Among various types of fluorophores, all‐inorganic perovskite nanocrystals (NCs) are emerging candidates as absorbers/emitters in LSCs due to their size/composition/dimensionality tunable optical properties and high photoluminescence quantum yield (PL QY). However, due to the large overlap between absorption and emission spectra, it is still challenging to fabricate high‐efficiency LSCs. Intriguingly, zero‐dimensional (0D) perovskites provide a number of features that meet the requirements for a potential LSC absorber, including i) small absorption/emission spectral overlap (Stokes shift up to 1.5 eV); ii) high PL QY (>95% for bulk crystal); iii) robust stability as a result of its large exciton binding energy; and iv) ease of synthesis. In this work, as a proof‐of‐concept experiment, Cs4PbBr6 perovskite NCs are used to fabricate semi‐transparent large‐area LSCs. Cs4PbBr6 perovskite film exhibits green emission with a high PL QY of ≈58% and a small absorption/emission spectral overlap. The optimized LSCs exhibit an external optical efficiency of as high as 2.4% and a power conversion efficiency of 1.8% (100 cm2). These results indicate that 0D perovskite NCs are excellent candidates for high‐efficiency LSCs compared to 3D perovskite NCs.

Published: May 2019

AbstractRecent advances in device design and process optimizations have enabled the production of CdTe devices on flexible substrates, but the necessary high‐temperature processing (>450 °C) to recrystallize grains limits the use of alternative lightweight substrates. Here, a new synthesis method is reported to create a freestanding CdS/CdTe film by combining high‐temperature depositions (CdS/CdTe on Si/SiO2) and a simple lift‐off process in a water environment at room temperature. Analysis of the results indicate that the delamination is facilitated by the innate lattice mismatch as well as the presence of an unexpected Te‐rich layer (≈20 nm), which accumulates on the SiO2 surface. High‐resolution electron microscopy and spectroscopy measurements confirm that the CdS/CdTe film is physically liberated from the substrate without leaving any residue, while also preserving their initial structural and compositional properties.
Semiconductor Thin Film Based Metasurfaces and Metamaterials for Photovoltaic and Photoelectrochemical Water Splitting Applications

Published: May 2019

AbstractIn both photovoltaic (PV) and photoelectrochemical water splitting (PEC‐WS) solar conversion devices, the ultimate aim is to design highly efficient, low cost, and large‐scale compatible cells. To achieve this goal, the main step is the efficient coupling of light into active layer. This can be obtained in bulky semiconductor‐based designs where the active layer thickness is larger than light penetration depth. However, most low‐bandgap semiconductors have a carrier diffusion length much smaller than the light penetration depth. Thus, photogenerated electron–hole pairs will recombine within the semiconductor bulk. Therefore, an efficient design should fully harvest light in dimensions in the order of the carriers' diffusion length to maximize their collection probability. For this aim, in recent years, many studies based on metasurfaces and metamaterials were conducted to obtain broadband and near‐unity light absorption in subwavelength ultrathin semiconductor thicknesses. This review summarizes these strategies in five main categories: light trapping based on i) strong interference in planar multilayer cavities, ii) metal nanounits, iii) dielectric units, iv) designed semiconductor units, and v) trapping scaffolds. The review highlights recent studies in which an ultrathin active layer has been coupled to the above‐mentioned trapping schemes to maximize the cell optical performance.
