A Contextualized Meaning-Recall Vocabulary Testing Platform
Authors:   University of Niigata Prefecture, Stoeckel Tim
Published: October 2023

In contextualized vocabulary assessment, target words appear in extended context. Compared to tests employing single-word or limited-context prompts, research suggests that contextualized assessment is more reliable and demonstrates better concurrent validity. In meaning-recall vocabulary assessment, examinees retrieve target-word meaning from memory and typically demonstrate knowledge via a written L2-to-L1 translation. Compared to multiple-choice formats, meaning-recall yields more reliable data, correlates more strongly with reading comprehension, and is less influenced by guessing and test strategies. To facilitate these approaches to vocabulary assessment, this article introduces a resource for teachers and researchers to create, administer, and mark contextualized meaning-recall tests. Users input a passage, select target items, and share the test URL with examinees. Examinees then provide L1 translations or L2 synonyms, definitions, or explanations of target words in input boxes below the lines of text. Raters mark responses online, and these judgments can be saved for partial automatic marking in future test use. 文脈化された語彙測定では、ターゲット項目が段落の中に現れる。単一語彙または限られた文脈の項目を用いるテストに比べて、文脈化された測定はより信頼性が高く、より優れた併存的妥当性を示している。意味想起語彙テストでは、受験者はターゲット語彙の意味を思い出し、通常は第二言語（L2）から第一言語（L1）への書記による翻訳で知識を示す。多肢選択形式と比較して、意味想起はより信頼性のあるデータをもたらし、読解力とより強い相関を示し、推測やテスト戦略の影響を受けにくい。語彙測定へのこれらのアプローチを支持するために、本稿では教師や研究者が文脈化された意味想起テストを作成、実施、採点するためのリソースを紹介している。利用者は文章を入力し、問題項目を選択、テストのURLを受験者と共有する。受験者は、テキストの下にある入力ボックスに対象語のL1翻訳やL2同義語、定義、またはその説明を入力する。採点者はオンラインで回答を評価し、正答とみなされる解答は将来のテスト利用時の自動採点のために保存できる。
The Lived Experience of Fanfiction Writers: Its Implications to Language Writing Skills
Authors: Reyes April Rose C. De Los , Pit Noel N.
Published: October 2023

Fanfiction writers have their own stories to tell as to why they were hooked into this form of writing.  These stories are relevant to the teaching of skills in writing.  Limited studies were found about the writing experiences of fanfiction writers.  This study explored the experiences with the overarching question: What is fanfiction writing as a lived experience among fanfiction writers? A transcendental phenomenology design was used to explore these experiences.  A three-phase phenomenological face-to-face interviews was conducted to collect the data.  Informal conversations and observations were also held.  Each interview was transcribed and sent back to each writer for checking and validation.  Actual fanfiction works were also observed.  From the data that were manually coded and categorized, three themes emerged from the eight categories such as outpouring and relief, transformation and connection, and development and motivation. Fanfiction writers write to express themselves as who they are including their feelings, their opinions, and their social interactions.  Fanfiction writing also enables them to develop their skill and passion for writing.  These experiences may help in skill-based teaching and learning especially in language classes.

Sustainable development is the most significant global goal and the economic cornerstone of achieving it is the transition towards a new, innovational model – the circular economy model. This process is the main driver of business evolution in many countries and it promotes the changes in current competitive strategies in line with best world practices. In the modern conditions of drastic transformation of global and national business spheres and intensifying competition the importance of the transition towards circular economy rises even more. The article focuses on circular business models widely embraced by national and foreign companies. The authors highlight different approaches towards classification of circular business models. It is underlined that the McKinsey ReSOLVE framework is the most practice-oriented one as it provides a detailed plan of establishing circular economy. The relevance of the topic is noting the role of circular models as promising competitive advantages. The authors demonstrate real examples of its usage thus showing the opportunities of it in competitive strategies. It is pointed out that possibilities of implementation of circular business models among industries and their economic returns vary. The special attention is drawn to the ‘virtualization’ model as it can be applied to many spheres with different effectiveness. The conducted research also proves that potential benefits of the business models in question go along with substantial costs of the transition period. The basic conclusion is the rising role of the circular economy business models in shaping modern commercial field.

The development of eco-friendly and biodegradable adsorbent with excellent adsorption performance is of great importance for the efficient dye removal in wastewater. Herein, an efficient and biodegradable composite adsorbent bead was fabricated from cellulose acetate (CA) modified with low molecular weight polyethylene glycol 200 (PEG200) for the adsorptive removal of methylene blue dye (MB) from aqueous solution. The weight fraction of PEG was varied to investigate the effect of material bead composition on the morphology, molecular structure, crystal phases, thermal stability, mechanical properties, and adsorption performance of the composite beads. Batch adsorption was carried out at various times to estimate the time at equilibrium adsorption capacity and kinetic model. Various operating conditions such as pH, initial MB concentration, and adsorbent dosage in experiment were also executed to examine the adsorption performance of this system. The result showed that all beads have porous structure and the pore size increase after the addition of PEG200. The adsorption capacity and % MB removal generally showed an improvement with the rise of PEG content. The batch adsorption experiments demonstrated that the best % removal and adsorption capacity of MB were 93.35 % and 28.005 mg/g, respectively, that was obtained by composite CA/PEG200 (80/20) bead at pH of 11, initial MB concentration of 30 mg/L, and bead dosage of 1 g/L. The adsorption kinetic fitted well to Elovich-kinetic model with average R2 of 0.844. Overall, this work offers new finding into the development of effective, environmentally friendly, and inexpensive cellulose-based adsorbents for wastewater remediation.

Collaborative drumming experiences forming part of an arts-based autoethnographic doctoral study.
Authors: Venter Zettie
Published: October 2023

In my doctoral study with the title A Collaborative Exploration of Pedagogical Refrain within Science Education, amongst others, I explored how community drumming as a collaborative process of artmaking can contribute to the verbalizing of preverbal sensory and imaginary knowledge in ways that can convey intersubjective meaning.

On 18 September 2021, some peers and I had drumming sessions with Jaco Spies (Drumability) exploring our educational journeys. From March 2022 worked with Bevil Spence, a community drummer who established a non-profit community organization, Drumba. Bevil is known for using his unique Drum360o pedagogy during the facilitation of drum circles. I completed a drumming facilitators course with Bevil and drummed with him at community drum circles at Amari Special School in Welkom, Free State, in Longstreet Cape Town, as well as at Herbet School for Autistic Learners in Cape Town, Western Province.
Variables Impacting Academic Writing: An Investigation of First-year TVET Students’ Writing Performance
Authors: Meyers Angelo , Smith Cornelia , Cekiso Madoda
Published: October 2023

This study aimed to investigate the variables affecting first-year TVET students’ academic writing performance in South African Higher Education. The study was quantitative in nature and a purposive sampling technique was used to select participants. The study was targeted at first-year students in Technical and Vocational Education and Technology (TVET) College in the Western Cape. The sample size of the study was 185 students. The results clearly indicated that students’ motivation for academic writing was the most important, with the highest mean. In addition, learning styles and strategies, study behaviour or study habits, difficulty managing time, and inadequate and poor-quality learning materials exert an influence on academic writing performance. It emerged from the study’s findings that motivation is an essential attribute first-year students must possess to enhance their academic writing at the tertiary level. Lack of motivation to develop academic writing skills can hinder them from acquiring the necessary skills. Most of the students asserted that academic writing posed challenges. The study concluded that there is a need for first-year students in colleges to devote time and be committed to academic writing to develop and improve student writing skills. It was revealed that attention paid to academic writing can facilitate overcoming many barriers apparent to students’ writing performance.

Published: October 2023

The finite volume method was used to study the characteristic of contaminated aviation fuel with the aim of reducing its flammability and post-impact fire. The flammability levels between pure Jet A-1 and contaminated Jet A-1 are compared using their flashpoints and fire points before and after the introduction of Liquid Nitrogen. Upon heating different mixing ratios (4:1, 3:1, and 2:1), results are analyzed to identify the best volume ratio exhibiting the highest reduction in flammability. Analysis shows that the mixing ratio of 2:1 not only froze but increased the flashpoint of the mixture from (48 ˚C–50 ˚C) to 64 ˚C. For the mixing ratio of 3:1, there was a rise in flashpoint to about 56 ˚C and partial freezing was seen at the topmost surface. At a mixing ratio of 4:1, it was observed that the effect of liquid nitrogen on Jet A-1 was minimal leading to a slight rise in its flash point (50 ˚C). Thus, liquid Nitrogen had a substantial effect on the flammability and flash point of Jet A-1 when mixed in the ratio (2:1) with a freezing time of 30 seconds and an unfreezing time of 17.5 minutes. Hence, Liquid Nitrogen can be used for the flammability reduction of Jet A-1.

Phosphorus and Lake Eutrophication: Recent Findings and Emerging Challenges
Authors: Van Cappellen Philippe
Published: October 2023

This presentation reviews some recent and ongoing research on phosphorus (P) cycling in a variety of lake systems. Phosphorus is an essential nutrient element, and its anthropogenic enrichment is generally considered to be the main driver of cultural eutrophication of freshwater lakes, which, in the worst case, leads to the occurrence of harmful algal blooms, the intensification of hypoxia and the die-off of aquatic life. The research presented shows that excess external P loading causes the accumulation of reactive chemical P forms in the bottom sediments of lakes (Update #1). The slow release of this reactive legacy P back to the water column can significantly delay a lake’s recovery following the reduction of external P loading (Update #2). Land use changes accompanying agricultural intensification and urbanization generally increase P emissions, but the implementation of agricultural and stormwater best management practices can effectively mitigate external P loads to receiving lakes (Update #3). However, additional stressors, including climate change and salinization, magnify in-lake P mobilization pathways and, hence, increase the risks of lake (re-)eutrophication (Update #4).
Biodegradation of Benzene Under Microaerobic Conditions: a Groundwater Microcosm Experiment Combined with a Multiomics Approach and DNA Stable Isotope Probing
Authors: Tancsics Andras , Bedics Anna , Soares André , Kriszt Balázs
Published: October 2023

Monoaromatic hydrocarbons such as benzene, toluene, ethylbenzene, and xylene (BTEX) are the most common contaminants of the groundwater and can easily contaminate drinking water sources due to their relatively high water solubility. Among these compounds, benzene is known to have carcinogenic properties and is considered to be persistent under anoxic conditions. Although deep knowledge was acquired both on the aerobic and anaerobic degradation of benzene in the past three decades, the diversity of those bacteria which are able to degrade it under microaerobic conditions, is still unknown. To come over this limitation aerobic and microaerobic benzene-degrading microcosms were established using groundwater sediment of a BTEX-contaminated site and the evolved bacterial communities were investigated through a polyphasic approach including multiomics analysis and DNA stable isotope probing. The obtained results shed light on the fact that the aerobic and microaerobic benzene-degrading bacterial communities were distinctly different. In the aerobic microcosms members of the genus Pseudomonas overwhelmingly dominated the bacterial communities by showing even 40-50% abundance. In contrast, under microaerobic conditions members of the genera Azovibrio and Malikia dominated the communities, while the abundance of Pseudomonas drastically decreased compared to that of was observable in the aerobic microcosms. Results obtained by the analysis of microcosms spiked with 13C6-benzene confirmed these observations. In heavy DNA fractions obtained from the aerobic microcosms the enrichment of Pseudomonas and Rhizobiaceae-related 16S rRNA gene fragments was observable. At the same time, labelled DNA from the microaerobic microcosms contained mostly Azovibrio and Malikia-related sequences, while the abundance of Pseudomonas 16S rRNA gene sequences was below 2%. Besides, by using metagenomic dataset of a previous microaerobic experiment we managed to reconstruct an Azovibrio genome, in which a complete meta-cleavage pathway for the aerobic degradation of aromatic hydrocarbons was identified. Overall, it can be concluded that under microaerobic conditions members of Comamonadaceae and Rhodocyclaceae can be the key benzene degraders in contaminated subsurface environments.
Genetic evidence that multiple cytochrome nanowires are necessary for Fe(III) oxide reduction in Geobacter sulfurreducens
Authors: Ammend Madeline , Chan Chi , Bond Daniel
Published: October 2023

Geobacter sulfurreducens is a dissimilatory metal-reducing microorganism capable of utilizing insoluble acceptors via extracellular electron transfer. While a large number of multiheme c-type cytochromes expressed by G. sulfurreducens are implicated in linking its cytoplasmic respiratory chain to materials beyond its outer membrane, whether these proteins have specific roles in reduction or recognition of particular metals is unknown. Recently, structures of three extracellular conductive c-type cytochrome filaments, often referred to as nanowires, were reported. Comprised of either OmcS, OmcE, or OmcZ, these nanowires are long polymers of protein subunits with a core of closely spaced hemes, with no similarity in sequence, fold, glycosylation, subunit size, or diameter. We utilized a markerless deletion approach to construct single, double, and triple-deletion strains in an isogenic background to investigate possible roles of OmcS, OmcE, and OmcZ. When soluble Fe(III) or the organic acceptor fumarate were electron acceptors, no defects were observed in any mutant. When freshly precipitated Fe(III) oxide was tested as an electron acceptor, mutants lacking omcE were strongly affected, reducing Fe(III) approximately half as fast. No other single mutant (∆omcS or ∆omcZ) showed a defect. Double mutants containing only omcE (∆omcSZ) also showed a defect, suggesting other proteins could be required in addition to OmcE. The double mutant containing only omcZ (∆omcSE) also showed a partial defect, while double mutants containing only omcS (∆omcEZ) were completely unable to reduce Fe(III) oxide. The triple (∆omcESZ) mutant was also unable to reduce Fe(III) oxides. Taken together, this indicates that genes for two separate nanowires are necessary to completely reduce this form of Fe(III) oxide. This is the first evidence that omcZ, which has only been implicated in electron transfer to electrodes, could also be needed for metal reduction. With the recent discovery of two completely unrelated mutltiheme cytochrome nanowires in thermophilic Archaea, different conductive filaments with different substrate specificities may have repeatedly evolved to facilitate extracellular respiration.
Historical reconstruction of the invasions of four non-native tree species at local scale: a detective work on Ailanthus altissima, Celtis occidentalis, Prunus serotina and Acer negundo
Authors: Erdélyi Arnold , Hartdégen Judit , Malatinszky Ákos , Vadász Csaba
Published: October 2023

Reconstructing the history (spatio-temporal patterns) of biological invasions at a small spatial scale is challenging, notably because the required data are often not available in sufficient quantity and quality. In this study, we present a mixed approach using six different data sources to explore the spreading history of four non-native invasive tree species, Ailanthus altissima, Celtis occidentalis, Prunus serotina and Acer negundo in a high conservation value foreststeppe habitat with an area of 1000 ha (Peszér Forest, Central Hungary). We carried out a literature search, compiled all the archived and currently valid data of the National Forestry Database (NFD) in a GIS database, conducted a full-coverage field survey, mapped all the large/old tree specimens and carried out annual ring counts, performed a hotspot analysis on the abundance data provided by the field survey and gathered local knowledge. Each of these approaches proved indispensable and their complementary use made it possible to reconstruct the invasion history of all four tree species. According to the available source literature, P. serotina was first planted in the area in 1937 and the first known occurrence of A. altissima could also be traced back to the 1930s. The examination of large specimens of C. occidentalis and querying the NFD for data related to A. negundo provided evidence that these species have been present in the area since at least the 1940s. However, based on the NFD and local knowledge, it is certain that the rapid expansion of the four tree species occurred simultaneously and only around the turn of the millennium, with a lag of at least 60-70 years. The exploration of local knowledge revealed three possible explanations, which interestingly also coincided in time. With the change in the political regime, the intensity of forest use started to decrease in the 1990s, the population of game was drastically reduced at the end of the decade and droughts became more frequent from 2000 onwards. The field survey clearly showed that these tree species were 2-3 times more prevalent and abundant than the relevant NFD data indicated. Finally, the primary hotspots of A. altissima and A. negundo overlapped with the locations of their first known occurrences, while in the case of C. occidentalis and P. serotina, they did not. However, local knowledge revealed that the former two had been ignored since at least the 1950s, while the latter two were occasionally planted until the 1990s. It is likely that the primary hotspots of C. occidentalis and P. serotina indicate the locations of these undocumented plantations.

Un nouveau paradigme : interprétation bionienne du rêve
Authors: Hebbrecht Marc
Published: October 2023

Tandis que Freud part du principe que le rêve transforme un désir inconscient, Bion est d’avis que le rêve resynthétise des éléments psychiques fragmentés en un ensemble. D’abord, les expériences sont rendues aptes à être rêvées. Ceci signifie que des expériences sensorielles sont soumises à des processus tels que la perception, l’observation, l’attention, la pensée, la mémorisation. Pour Bion, le rêve en tant que processus équivaut à la pensée inconsciente éveillée et avec la rêverie. Les psychotiques ne sont pas en mesure d’avoir de véritables rêves ; leurs expériences visuelles apparaissant pendant le sommeil n’ont donc pas le caractère de rêves, mais sont des cauchemars ou des hallucinations survenant pendant le sommeil. Le rêve n’est pas seulement à comprendre comme une activité de pensée spécifique, mais aussi comme un stade de la pensée de la personne. Un rêve peut être compris comme une suite rapide et éphémère qui survient brièvement, puis retombe en éléments séparés. Le rêve constitue le résultat du processus de transformation. L’analyse du rêve selon Bion, après 1970, implique que l’analyste s’ouvre au rêve du patient et se laisse fortement influencer par celui-ci. Le rêve du patient est prolongé, travaillé et complété. Dans ce modèle, le rêve de contre-transfert, à savoir le rêve de l’analyste sur le patient, est très important.
Bion et Beckett : les jumeaux imaginaires
Authors: Armstrong Mimi
Published: October 2023

Wilfred Bion et Samuel Beckett, deux géants du XX e  siècle, se sont rencontrés tout au début de leurs carrières respectives : Beckett a fait un travail psychanalytique avec Bion trois fois par semaine pendant deux ans ! Cet article cherche à mettre en lumière leurs relations réelles, imaginaires et inconscientes (de ce que nous pouvons en imaginer). Certains parallèles de leurs vies, certaines similarités d’idées, des façons parfois semblables de s’exprimer suggèrent des liens intellectuels et émotionnels profonds, bien que largement inconscients, alors qu’à partir de 1935, plus aucun contact n’a eu lieu entre eux. Les traces de ces liens et nos réflexions à leur égard sont développées ici.
L’environnement non humain de Searles, revisité à la lumière de la théorie de la pensée de Bion et à l’ombre de la crise environnementale
Authors: Magnenat Luc
Published: October 2023

L’auteur met en perspective deux textes d’Harold Searles qui parlent d’environnement « non humain ». Le premier, L’environnement non humain (1960), étudie les mouvements d’humanisation et de déshumanisation inhérents à la clinique psychotique. Dans le second, Unconscious processes in relation to the environmental crisis (1972), Searles s’intéresse à l’environnement compris dans son acception écologique et considère la crise environnementale comme une conséquence de nos défenses contre le « non humain » en nous. L’auteur développe le sujet à l’aide de la théorie de la pensée de Bion et de concepts tels que ceux de désastre primitif et de clivage forcé.
Assumer une responsabilité relationnelle : un facteur de résilience en Australie aborigène
Authors: Moïsseeff Marika
Published: October 2023

Parmi les mesures consécutives à la discrimination raciale des Aborigènes australiens par les Britanniques à la suite de la colonisation, l’une des plus néfastes a sans doute été de déposséder les parents de leurs responsabilités vis-à-vis de leurs enfants, dépossession particulièrement brutale lorsque les enfants étaient métis puisqu’ils étaient alors systématiquement retirés de leurs familles aborigènes pour être placés en institution ou donnés en adoption. Les conséquences délétères et persistantes en sont aujourd’hui connues et celles qui touchent la thématique de cet article renvoient au taux de suicide et, plus généralement, à la mortalité prématurée ainsi qu’aux troubles des conduites particulièrement élevés chez les jeunes Aborigènes, notamment les garçons. À partir du récit de la mise en place d’une équipe masculine de basket dans la communauté où l’auteur, pédopsychiatre et ethnologue, travaille depuis plus de 25 ans, elle met en évidence l’un des facteurs de résilience qu’elle a pu repérer : la transmission de la responsabilité relationnelle.
« Voyage en sexualité adolescente » ou « La chair de ma mère »
Authors: Benjelloun Amine
Published: October 2023

Nous exposons deux cas cliniques à la prise en charge difficile, dans un espace envahi par des forces traumatiques écrasant le travail psychique, où le registre de l’acte et la prise de risques donnent à la sexualité une place envahissante dont le destin n’est ni le désir ni le plaisir. Nous montrons comment l’appui sur l’œuvre littéraire de Georges Bataille, nous a permis d’écouter l’inentendable, de survivre aux cotés de nos patients, en permettant un travail représentationnel contre transférentiel.

This work presents a comparative finite element analysis of a 3-wheeler novel robot chassis used for uneven terrain robot applications. The chassis was modeled using SolidWorks and further analyzed in Ansys for its total deformation, equivalent stress, equivalent elastic strain and thermal strain. Two materials were taken into consideration for comparative analysis: Aluminium alloy and Structural steel. A load (force) of 500 N was distributed on the chassis uniformly and an acceleration of 5 mm/sec2 was given. Thermal conditions were added by raising the temperature from 22°C to 50°C in 1 sec. The analysis performed was majorly divided into three parts: a) Only considering force, b) Considering force as well as acceleration, c) Considering force, acceleration and thermal conditions. Total deformation in Aluminium alloy was observed 1.51 to 2.79 times that of structural steel in all the cases. Both metals exhibited almost identical equivalent stress in absence of thermal effect and structural steel exhibit 1.5 times that of Aluminium alloy at elevated temperature. Aluminium alloy possess relatively more (1.86-2.63 times) equivalent elastic strain compared to structural steel. Although, distribution of thermal strain remained constant throughout the chassis for both the materials, its magnitude was 1.91 times high in Aluminium alloy. This type of analysis helps in evaluating the current design and decide whether it will sustain the required load and acceleration under given thermal conditions
Depth Treatment of Engineering Applications Wastewater Using a Sequential Heterogeneous Fenton and Biodegradation Approach: Review
Authors: Abdulkareem Sheam Bahjat
Published: October 2023

After treating industrial wastewater efficiently and adequately to avoid harm from it being reused and disposed of in the past, the majority of countries in the world have moved to integrated planning and sound management to reuse it. The efficiency of water treatment and reuse depends on a set of environmental standards and controls that are connected to the nature of this water and the eventual purpose of treating and reusing it in order to prevent the environmental repercussions of an integrated method. A framework that assures environmental protection must be employed for this treatment and reuse. The emphasis is on developing reusable resources in order to transition from a linear to a circular economy. Finding the primary pathway for heterogeneous and homogeneous catalysis to pollutant degradation, optimizing the layout for integrating Fenton processes into large-scale treatment plants, particularly its coupling with biological treatment, and analyzing or enhancing heterogeneous catalyst lifetime are all important. are some of the main challenges mentioned in this research. This study intends to analyze the efficacy of the Fenton process in treating water in an effective and economical way compared to other conventional techniques.

Published: October 2023

In this work, the black rice husk ash (BRHA), a pozzolanic material, was used as a partial replacement in concrete with the weight percentages of 0%, 10%, 20%, 30%, 40% and 50% for enhancing the corrosion resistivity in the marine environment. The compressive strength, corrosion by accelerated corrosion test by impressed voltage (ACTIV), and chloride (Cl−) penetration of concrete specimens were investigated after 28 days of curing. For corrosion and chloride penetration analyses, the 20% of BRHA replacement specimen was the most effective concrete specimen because the deformation was not observed within 19 days of the test. The cement specimens with lower BRHA percentages were cracked due to the development of stress by the rust formation. For higher BRHA percentages, the protective Fe2O3 was dissolved due to the acidic environment caused by higher chloride accumulation in the cement specimens. The steel rebar was then aggressively attacked by the chloride and it was finally broken. Therefore, the optimization of the BRHA percentage is needed to minimize corrosion. However, the longer curing time of 20% BRHA replacement specimen is required for increasing the compressive strength because its compressive strength is slightly lower than the standard.

Published: October 2023

In the present work, Thermo elastic analysis is performed on a functionally graded cylinder to investigate combined effect of pressure and thermal load. It is assumed that the material of the cylinder is functionally graded in which the properties are vary continuously along the thickness based on a power law function. Results are obtained using Finite element-based software ANSYS. To know the accuracy of the present approach, results are confirmed with available literature. Furthermore, the effect of the temperature rising on the distribution of the displacement and stress for different values of gradation index are investigated in the paper. From the results it is concluded that replacing the traditional material with functionally graded material is helpful in the design of pressure vessels.

Published: October 2023

Background: Recently, there has been a marked increase in the incidence of cancer, HIV, and other noncommunicable diseases globally. Thus, the demand for palliative care (PC), including end-of-life care, continues to grow worldwide. Physiotherapy has an important role in PC as it aims to alleviate symptoms and improve quality of life by optimising independent levels of function.Objective: To assess the level of knowledge, awareness and current practice of PC amongst Nigerian physiotherapists in clinical practice.Method: Our study used a cross-sectional descriptive census-based method and recruited practising physiotherapists in Nigeria. An electronic questionnaire was used to collect data over 12 weeks, comprising 36 semistructured questions in four domains: personal information, knowledge, awareness and current practices regarding PC. Data were analysed using a pragmatist paradigm.Results: Of the 426 physiotherapists who participated, 50% (n = 213) had a postgraduate degree, 49.5% (n = 211) had a bachelor’s degree and 0.5% (n = 2) had a Doctor of Physical Therapy degree. The results also indicate that 73.9% (n = 315) of the participants had sufficient knowledge about PC, 80.5% (n = 343) had a sufficient level of awareness about PC and 66.7% (n = 284) were using current clinical practices in the rehabilitation of critically ill patients or those with chronic conditions.Conclusion: It was concluded that most Nigerian physiotherapists had sufficient knowledge and awareness about PC and were involved in the management of patients requiring PC physiotherapy.Clinical implication: It can be understood that a large proportion of Nigerian physiotherapists have clinical experience managing patients requiring PC, despite inadequate formal training in this field.

Background:

Asymptomatic bacteriuria (ASB) during pregnancy can lead to symptomatic urinary tract infection (UTI), with increased fetal and maternal morbidity and mortality. We evaluated the incidence, clinical and microbiological profile, and outcome of ASB in pregnant women attending our antenatal clinic.

Materials and Methods:

This prospective study was conducted on 3769 pregnant women in a routine antenatal clinic at a tertiary care center. Participants were divided into two groups, ASB and non-bacteriuria. Data were collected in a standard proforma and analyzed using the software Statistical Package for the Social Sciences (SPSS) v. 20.

Results:

The incidence of ASB was 3.29% (124/3769). Majority of the women were in the age group of 21–30 years (78.76%,n= 89).Escherichia coli(61.06%) was the most common organism isolated. Maternal anemia (30.08% and 2.93% in the ASB and non-bacteriuria groups, respectively), low birth weight (LBW; 42.5% and 27.98% in the ASB and non-bacteriuria groups, respectively), intrauterine death (4.4% and 1.4% in the ASB and non-bacteriuria groups, respectively), and preterm delivery (37.2% and 22.31% in the ASB and non-bacteriuria groups, respectively) were were associated with ASB (P= 0.001).

Conclusions:

ASB was associated with maternal anemia, preterm delivery, intrauterine death, and LBW. Early detection and treatment of ASB may result in favorable maternal outcome.
