Από την επαναστατημένη μάζα στη μαζική δημοκρατία
Authors: Παρούσης Μιχαήλ
Published: March 2023

Tο έργο του Παπαϊωάννου συμβάλλει αποφασιστικά στη συγκρότηση του γνωστικού αντικειμένου της Σύγχρονης Ελληνικής Φιλοσοφίας. Ο ίδιος εντάσσεται στη μεταπολεμική γενιά των σύγχρονων φιλοσόφων μας, εκείνη που κατ' αρχάς γοητεύτηκε από τον Μαρξισμό ως υλιστική φιλοσοφία, αλλά κατέληξε στην κριτική όχι μόνο του γραφειοκρατικού ολοκληρωτικού σοβιετικού μοντέλου, μα και στην απόρριψη των βασικών θέσεων του ίδιου του Μαρξ.  Τόσο ο Καστοριάδης, όσο και ο Παπαϊωάννου, ανανοηματοδοτούν την ιστορική αποτύπωση της κλασικής αρχαιότητας. Ο πρώτος στηρίζει σε αυτήν την αναζήτηση της αυτονομίας, ο δεύτερος τη συγκρότηση της έννοιας της "μάζας", καθώς συνδέει τη θεατροκρατία, ως το ενοποιητικό στοιχείο του Δήμου, με τους θεσμούς της άμεσης δημοκρατίας, για να στηρίξει μια θετική έννοια της μαζικής δημοκρατίας. Αυτή η έννοια αντιπαραβάλλεται με τις αντιλήψεις περί μαζικής κοινωνίας του 19ου και του 20ού αιώνα, από τον Λε Μπόν μέχρι τον Ρωλς και τους κοινοτιστές.

YOSYF GRODSKY AND BOSNIANS’ RUTHENIAN IN PERIOD 1878-1918
The article presents the person of Yosyf Grodsky, the greek-catholik clerk from Lviv, which was moved to Bosnia in 1907-1908. He was Methropolite Andrey Sheptytsky’s friend. He send Yosyf Grodsky to Bosnia because Sheptytsky wanted to know the lives of Ruthenian farmers who came from villages in Bosnia. Also he wanted popularize topic of Ruthenian colonisation in Bosnia and Hercegovina. In 1909 Grodsky published book Positon of the Ruthenian from Bosnia. The article presentes some information about this book, and I would like to show more details about Ruthenian society in this part of Balkan Peninsula in the Austro-Hungarian period.

Note-taking for interpreting is a specialist skill originally developed to assist conference interpreters to remember the contents of long speeches when interpreting consecutively in a unidirectional mode. The bulk of the research into note-taking has been in relation to the classic consecutive interpreting mode in international settings, with little research into the use of note-taking in legal interpreting settings. This paper presents the results of a study on note-taking by 13 court interpreters in a simulated criminal trial in Sydney, Australia. It reports the results of interpreters’ note-taking practices, taking into account their language combination, their own perceptions of mental effort and the usefulness of notes as well as their overall interpreting performance.

Authors: Ferdowsi Sima , Hadipour Hoda , Hasan Razmi Mohammad
Published: March 2023

The present study aimed to develop and validate an instrument to measure Iranian translators’ book selection criteria (TBSC). A mixed-methods approach was adopted to conduct the research. During the qualitative phase, the researchers developed the first draft of the questionnaire by generating items through focus groups and literature review. This led to constructing a 40-item closed-ended questionnaire ranging on a 6-point Likert scale from 1 (strongly disagree) to 6 (strongly agree). Participants of both phases were selected by snowball sampling and participated voluntarily in the study. The quantitative approach was used to pilot the web-based questionnaire with 50 participants. To assess the psychometric properties of the final instrument, a sample of 251 translators completed the questionnaire. The revised and modified version of the TBSC scale included 34 items loaded on six subscales, namely general considerations, external motivating factors, success guarantee factors, translator’s authority/agency, internal motivating factors, and finally, publisher’s authority/agency. The study’s findings indicate that the TBSC is a valid and reliable (α = .748) instrument to measure the criteria affecting the translator’s book selection in the context of Iran.
The Value of Social Media Data in Fashion Forecasting
Authors: Fu Youran , Fisher Marshall
Published: March 2023

Problem definition: How to use social media to predict style color and jeans fit sales for a retailer. Academic/practical relevance: Neither retail practice nor the academic literature provides a method for using social media to predict style color and jeans fit sales for a retailer. We present and validate a systematic approach for doing that. Methodology: Demand forecasting in the fashion industry is challenging due to short product lifetimes, long manufacturing lead times, and constant innovation of fashion products. We investigate the value of social media information for color trends and jeans fit forecasting. We partner with three multinational retailers, two apparel and one footwear, and combine their proprietary data sets with web-crawled publicly available data on Twitter and the Google Search Volume Index. We implement a variety of machine learning models to develop forecasts that can be used in setting the initial shipment quantity for an item, arguably the most important decision for fashion retailers. Results: Our findings show that fine-grained social media information has significant predictive power in forecasting color and fit demands months in advance of the sales season, and therefore greatly helps in making the initial shipment quantity decision. The predictive power of including social media features, measured by the improvement of the out-of-sample mean absolute deviation over current practice ranges from 24% to 57%. Managerial implications: To our knowledge, this study is the first to explore and demonstrate the value of social media information in fashion demand forecasting in a way that is practical and operable for fashion retailers. With consistent results across all three retailers, we demonstrate the robustness of our findings over market and geographic heterogeneity, and different forecast horizons. Moreover, we discuss potential mechanisms that might be driving this significant predictive power. Our results suggest that changes in fashion demand are driven more by “bottom-up” changes in consumer preferences than by “top-down” influence from the fashion industry.

Objective: We’ve aimed at evaluating whether the platelet mass index (PMI) can be a prognostic marker for children diagnosed with MIS-C.
Material and Methods: 31 children diagnosed with MIS-C and treated at our university hospital between March 2020 and November 2021 were included. Demographic data, clinical findings and laboratory values at the time of hospitalization, admission to the intensive care unit and duration of hospitalization were evaluated retrospectively. PMI of each patient at the time of hospitalization was calculated and recorded.
Results: There was a statistically significant negative correlation between PMI and ferritin (r= -0.635, moderate, p<0.001), CRP (r= -0.377, weak, p= 0.036), and procalcitonin (r= -0.481, weak, p=0.006) levels. There was a statistically significant positive relationship between PMI and leukocyte count (r=0.367, weak, p=0.042) and lymphocyte count (r=0.384, weak, p=0.033). Median PMI values of the patients requiring intensive care (1701.35 fl/nl) were lower, compared to the median PMI values of the patients not requiring intensive care (2523.94 fl/nl), however, statistical results could not be reached due to the low (4 of 31) number of patients requiring intensive care. Median PMI values of the patients whose ferritin level was >400 ng/ml (1415.2; 533.4 – 3600.5) were statistically lower compared to the median PMI values of the patients whose ferritin level was ≤400 ng/ml (2705.7; 1395.2 – 9167.6).Conclusion: The findings in our study demonstrate that low PMI levels identified in children with MIS-C at the time of diagnosis may be with more severe clinical courses

Direitos fundamentais, interações entre espaços público-privados e urbanismo: um ensaio sobre as private cities
Authors: Carmona Paulo Afonso Cavichioli , Montenegro dos Reis Rhuan Filipe
Published: March 2023

O escritor italiano Dante Alighieri dizia que o direito é a proporção real e pessoal de um homem em relação a outro. Em tal equlíbrio, estão as cidades, centros dinâmicos que concentram simbologias e sentidos do nosso cotidiano. Mundo afora, nota-se fenômeno bastante recente, que desafia as divisões aritiméticas entre espaços públicos e privados, as chamadas cidades privadas, muitas delas formam centros socialmente tão coesos e distintos de seu entorno que levam à constituição de novas soberanias; outras parecem advir de acordos entre grandes empreendimentos e autoridades públicas ou da privatização de determinados serviços e rumos da administração urbana. Eis o objeto desse estudo, que tem como objetivo resolver, por meio do método da revisão bibliográfica sistemática ainda lacunosa, resolver alguns nós conceituais afetos a essas cidades. O problema de pesquisa passa pelo entendimento sobre a interação entre esses novos espaços e as ambiências públicas, ponderações apontadas nas considerações finais. Outrossim, sua delimitação teórica abrange essa premissa e as modulações dos direitos fundamentais nesses espaços, tais como segurança, meio ambiente, infraestrutura e mobilidade. Categorias e motivações dessas dinâmicas privadas inauguram a estrutura da pesquisa e, como arremate, encaminham-se discussões mais específicas sobre os direitos fundamentais enquanto resultados do presente levantamento.
Intermunicipal consortium for sustainable development and innovation of the state of Paraíba from the perspective of environmental democracy: an analysis of the organizational discourse
Authors: Morais Lucas Andrade de , Freitas Lucia Santana de
Published: March 2023

The objective of the present article is to identify the presence of elements of environmental democracy, access to information, and public participation, from the organizational discourse of an inter-municipal public consortium. To this end, it is proceeded by the qualitative approach, descriptive and documental research, on the reality of the organizational discourses of the Intermunicipal Consortium for Sustainable Development and Innovation of the State of Paraíba (CONDESPB). It was observed that the Intermunicipal Consortium, from the perspective of the guidelines of environmental democracy, presented incipient access to information, made by limited channels such as the website, and the access to public participation is non-existent, indirectly giving itself by electoral representation, being contrary to what the parameters of environmental democracy advocates in these two pillars, requiring the expansion of systems and information channels and the direct inclusion of the public and interest groups in environmental deliberations so that the practices of environmental democracy in CONDESPB are minimally instrumental only in the pillar of access to information.

Complications following ankle arthroscopy
Authors: Arshad Zaki , Aslam Aiman , Al-shdefat Sofyan , Khan Rahul , Jamil Omar , Bhatia Maneesh
Published: March 2023

Aims

This systematic review aimed to summarize the full range of complications reported following ankle arthroscopy and the frequency at which they occur.

Methods

A computer-based search was performed in PubMed, Embase, Emcare, and ISI Web of Science. Two-stage title/abstract and full-text screening was performed independently by two reviewers. English-language original research studies reporting perioperative complications in a cohort of at least ten patients undergoing ankle arthroscopy were included. Complications were pooled across included studies in order to derive an overall complication rate. Quality assessment was performed using the Oxford Centre for Evidence-Based Medicine levels of evidence classification.

Results

A total of 150 studies describing 7,942 cases of ankle arthroscopy in 7,777 patients were included. The overall pooled complication rate was 325/7,942 (4.09%). The most common complication was neurological injury, accounting for 180/325 (55.4%) of all complications. Of these, 59 (32.7%) affected the superficial peroneal nerve. Overall, 36/180 (20%) of all nerve injuries were permanent. The overall complication rate following anterior ankle arthroscopy was 205/4,709 (4.35%) compared to a rate of 35/528 (6.6%) following posterior arthroscopy. Neurological injury occurred in 52/1,998 (2.6%) of anterior cases using distraction, compared to 59/2,711 (2.2%) in cases with no distraction. The overall rate of major complications was 16/7,942 (0.2%), with the most common major complication – deep vein thrombosis – occurring in five cases.

Conclusion

This comprehensive systematic review demonstrates that ankle arthroscopy is a safe procedure with a low overall complication rate. The majority of complications are minor, with potentially life-threatening complications reported in only 0.2% of patients.

CT required to perform robotic-assisted total hip arthroplasty can identify previously undiagnosed osteoporosis and guide femoral fixation strategy
Authors: Bukowski Brett R. , Sandhu Kevin P. , Bernatz James T. , Pickhardt Perry J. , Binkley Neil , Anderson Paul A. , Illgen Richard
Published: March 2023

Aims

Osteoporosis can determine surgical strategy for total hip arthroplasty (THA), and perioperative fracture risk. The aims of this study were to use hip CT to measure femoral bone mineral density (BMD) using CT X-ray absorptiometry (CTXA), determine if systematic evaluation of preoperative femoral BMD with CTXA would improve identification of osteopenia and osteoporosis compared with available preoperative dual-energy X-ray absorptiometry (DXA) analysis, and determine if improved recognition of low BMD would affect the use of cemented stem fixation.

Methods

Retrospective chart review of a single-surgeon database identified 78 patients with CTXA performed prior to robotic-assisted THA (raTHA) (Group 1). Group 1 was age- and sex-matched to 78 raTHAs that had a preoperative hip CT but did not have CTXA analysis (Group 2). Clinical demographics, femoral fixation method, CTXA, and DXA data were recorded. Demographic data were similar for both groups.

Results

Preoperative femoral BMD was available for 100% of Group 1 patients (CTXA) and 43.6% of Group 2 patients (DXA). CTXA analysis for all Group 1 patients preoperatively identified 13 osteopenic and eight osteoporotic patients for whom there were no available preoperative DXA data. Cemented stem fixation was used with higher frequency in Group 1 versus Group 2 (28.2% vs 14.3%, respectively; p = 0.030), and in all cases where osteoporosis was diagnosed, irrespective of technique (DXA or CTXA).

Conclusion

Preoperative hip CT scans which are routinely obtained prior to raTHA can determine bone health, and thus guide femoral fixation strategy. Systematic preoperative evaluation with CTXA resulted in increased recognition of osteopenia and osteoporosis, and contributed to increased use of cemented femoral fixation compared with routine clinical care; in this small study, however, it did not impact short-term periprosthetic fracture risk.

Traceless encryption approach for physical layer security in coherent optical communications system
Authors: Zhao Zan-Shan , Li Pei-Li , Gan Wei-Ming
Published: March 2023

We proposed and numerically studied a traceless encryption approach for physical layer security in coherent optical communications system, the most attractive advantage of which is that it is hard for eavesdroppers to be aware that the transmission signal has been encrypted because the modulation formats of encrypted signal are still the regular ones, i.e. traceless encryption. In the proposed approach, the phase only or the combination of phase and amplitude dimensions can be used for encryption and decryption. Three simple encryption rules are designed and used to investigate the encryption security performance of the scheme, in which the QPSK signal can be encrypted to be as 8PSK, QPSK and 8QAM. The results show that three simple encryption rules can cause 37.5%, 25%, 62.5% of user signal binary codes to be misinterpreted by the eavesdroppers, respectively. When the modulation formats of encrypted signal and user signal are identical, the scheme can not only cover up the real information, but also have a potential application at misleading eavesdroppers. The impacts of the control light peak power at the receiver on the decryption performance are also analysed, the results indicate that the decryption performance of the scheme has a good tolerance to the peak power fluctuation of control light at the receiver.

Post-compression methods for ultrafast laser pulses typically face
challenging limitations, including saturation effects and temporal
pulse breakup, when large compression factors and broad bandwidths are
targeted. To overcome these limitations, we exploit direct dispersion
control in a gas-filled multi-pass cell, enabling, for the first time
to the best of our knowledge, single-stage post-compression of 150 fs
pulses and up to 250 µJ pulse energy from an ytterbium (Yb) fiber
laser down to sub-20 fs. Dispersion-engineered dielectric cavity
mirrors are used to achieve nonlinear spectral broadening dominated by
self-phase modulation over large compression factors and bandwidths at
98% throughput. Our method opens a route toward single-stage
post-compression of Yb lasers into the few-cycle regime.
Valley-Hall alternatively changing conductivity in gapped and strained graphene
Authors: Zhang Ya , Zhai Feng , Jiang Wei
Published: March 2023

We investigated the alternatively changing (ac) valley-Hall effect in a graphene/h-BN structure under the modulations of a static electric field E0, magnetic field B0, and light field EA1. The proximity to the h-BN film leads to a mass gap and strain-induced pseudopotential for electrons in graphene. Starting from the Boltzmann equation, we derive the ac conductivity tensor σ, including the orbital magnetic moment, Berry curvature, and anisotropic Berry curvature dipole. It is found that under B0 ≠ 0, σ for the two valleys can have different amplitudes and even have the same sign, leading to a net ac Hall conductivity. The ac Hall conductivities and the optical gain can be altered by both the amplitude and the direction of E0. These features can be understood from the changing rate of σ with E0 and B0, which is valley-resolved and varies nonlinearly with the chemical potential.

Published: March 2023

Orbital angular momentum densities in the astigmatic transformation of Lissajous geometric laser modes are originally and systematically investigated. The quantum theory of the coherent state is exploited to derive an analytical wave representation for the transformed output beams. The derived wave function is further employed to numerically analyze the propagation dependent orbital angular momentum densities. The parts of the negative and positive regions in the orbital angular momentum density are found to rapidly change in the Rayleigh range behind the transformation.
Photon-limited Cherenkov imaging of radiation therapy dose

Published: March 2023

Cherenkov imaging is a unique verification tool that could provide both dosimetric and tissue functional information during radiation therapy. However, the number of interrogated Cherenkov photons in tissue is always limited and tangled with stray radiation photons, severely frustrating the measurement the signal-to-noise ratio (SNR). As such, here, a noise-robust photon-limited imaging technique is proposed by comprehensively exploiting the physical rationale of low-flux Cherenkov measurements together with the spatial correlations of the objects. Validation experiments confirmed that the Cherenkov signal could be promisingly recovered with high SNR by irradiating at as few as one x ray pulse from a linear accelerator (10 mGy dose), and the Cherenkov excited luminescence imaging depth can be extended by >100% on average, for most concentrations of phosphorescent probe. This approach demonstrates that improved applications in radiation oncology could be seen when signal amplitude, noise robustness, and temporal resolution are comprehensively considered in the image recovery process.
Bound exciton luminescence and phonon sideband analysis of iodine intercalated bulk 2H-MoSe2 crystals
Authors: Siminel N. , Sushkevich K. , Aazou S. , Micu A. , Siminel A. , Sekkat Z. , Kulyuk L.
Published: March 2023

Temperature dependence of the luminescence spectra of MoSe2 crystals intercalated with I2 molecules has been investigated in the temperature range 11–100 K. The spectrum of luminescence, which is caused by the recombination of excitons bound on iodine molecules embedded in the van der Waals gap (vdW), consists of zero-phonon doublet at an energy less by 0.1 eV than the width of the indirect band gap of the host crystal, and its phonon replicas. The distance between the spectral lines of this A-B doublet constitutes Δ
AB
=5.6 meV. From the temperature dependence of the ratio of the A and B lines intensities, it was found, that the rate of radiative recombination of the exciton state B, which is responsible for the short-wavelength line B (EB = 1.0416 eV), is 76 times higher than the recombination rate of the A state (EA = .0360 eV). Based on a comparative analysis of the structure of the luminescence spectra at different temperatures and the measured Raman spectra, it is shown that the observed nine peaks of the phonon sideband are formed by only two vibrational modes with frequencies νph1 = 144 cm−1 and νph2 = 190 cm−1. The 1st frequency corresponds to the vibrational mode due to the second-order Raman process, and the 2nd – to the local vibrational mode induced by the halogen molecule embedded in the layered crystal structure. Finally, fundamental possibilities provided by the intercalation of halogen molecules in the interface of the van der Waals heterojunctions to modify their electronic properties are considered.
Ultracompact LiNbO3 ridge waveguide multi-mode interferometer based on low-effective-index mode interference

Published: March 2023

Waveguides fabricated in crystals, created by utilizing techniques such as ion implantation, femtosecond laser inscription, and proton exchange, have low refractive index contrast with the crystal substrate, which limits their potential development to create compact passive devices, such as waveguide interferometers. In this work, a new waveguide multi-mode interferometer fabrication strategy based on low-effective-index mode interference is presented. Numerical tools have been used for the analysis of this new guided-wave approach used for the device design. The research has demonstrated that a series of high-order modes with an effective refractive index much lower than the substrate can exist in trench-cladded ridge crystal waveguides that have a tiny index contrast in the vertical direction. Simple trench-cladded tapered waveguide configurations to excite such modes and to realize compact waveguide multi-mode interferometers with lengths of several tens and up to hundreds of micrometers are presented. The waveguide multi-mode interferometer design is compact in size, easy to modulate, and with low insertion loss. Furthermore, refractive index sensing is realized, with a sensitivity of ∼490 nm/RIU for aqueous solution samples. The novel multi-mode interference phenomenon present here offers new possibilities and significant opportunities for waveguide modulation and, thus, the development of compact waveguide refractometers.

Published: March 2023

Youth footballers need to be developed to meet the technical, tactical, and physical demands of professional level competition, ensuring that the transition between competition levels is successful. To quantify the physical demands, peak match intensities have been measured across football competition tiers, with team formations and tactical approaches shown to influence these physical demands. To date, no research has directly compared the physical demands of elite youth and professional footballers from a single club utilising common formations and tactical approaches. The current study quantified the total match and peak match running demands of youth and professional footballers from a single Australian A-League club. GPS data were collected across a single season from both a professional (n = 19; total observations = 199; mean ± SD; 26.7 ± 4.0 years) and elite youth (n = 21; total observations = 59; 17.9 ± 1.3 years) team. Total match demands and peak match running demands (1–10 min) were quantified for measures of total distance, high-speed distance [>19.8 km·h-1] and average acceleration. Linear mixed models and effect sizes identified differences between competition levels. No differences existed between competition levels for any total match physical performance metric. Peak total and high-speed distances demands were similar between competitions for all moving average durations. Interestingly, peak average acceleration demands were lower (SMD = 0.63–0.69) in the youth players across all moving average durations. The data suggest that the development of acceleration and repeat effort capacities is crucial in youth players for them to transition into professional competition.

The aim of this study is to explore the role of IL6 in predicting outcome in critically ill COVID-19 patients. Design Prospective observational cohort study. Setting 20-bed respiratory medical intensive care unit of Abderrahmen Mami Teaching Hospital between September and December 2020.

Methods

We included all critically ill patients diagnosed with COVID-19 managed in ICU. IL6 was measured during the first 24 hours of hospitalization.

Results

71 patients were included with mean age of 64 ± 12 years, gender ratio of 22. Most patients had comorbidities, including hypertension (n = 32, 45%), obesity (n = 32, 45%) and diabetes (n = 29, 41%). Dexamethasone 6 mg twice a day was initiated as treatment for all patients. Thirty patients (42%) needed high flow oxygenation; 59 (83%) underwent non-invasive ventilation for a median duration 2 [1–5] days. Invasive mechanical ventilation was required in 44 (62%) patients with a median initiation delay of 1 [0–4] days. Median ICU length of stay was 11 [7–17] days and overall mortality was 61%. During the first 24 hours, median IL6 was 34.4 [12.5–106] pg/ml. Multivariate analysis shows that IL-6 ≥ 20 pg/ml, CPK < 107 UI/L, AST < 30 UI/L and invasive ventilation requirement are independent risk factors for mortality.

Conclusions

IL-6 is a strong mortality predictor among critically ill COVID19 patients. Since IL-6 antagonist agents are costly, this finding may help physicians to consider patients who should benefit from that treatment.

Onchocerciasis caused by infection with Onchocerca volvulus is a disease of public health importance and is highly associated with disability. As Nigeria is aiming at eliminating onchocerciasis by 2030, there is a need to develop newer tools to map disease prevalence and identify environmental factors driving disease prevalence, even in places that have not been previously targeted for preventive chemotherapy. This study produced predictive risk-maps of onchocerciasis in Ogun State. Georeferenced onchocerciasis infection data obtained from a cross-sectional survey at 32 locations between March and July 2015 together with remotely-sensed environmental data were analyzed using Ecological Niche Models (ENM). A total of 107 field occurrence points for O. volvulus infection were recorded. A total of 43 positive occurrence points were used for modelling. ENMs were used to estimate the current geographic distribution of O. volvulus in Ogun State. Maximum Entropy distribution modeling (MaxEnt) was used for predicting the potential suitable habitats, using a portion of the occurrence records. A total of 19 environmental variables were used to model the potential geographical distribution area under current climatic conditions. Empirical prevalence of 9.3% was recorded in this study. The geospatial distribution of infection revealed that all communities in Odeda Local Government Area (a peri-urban LGA) showed remarkably high prevalence compared with other LGAs. The predicted high-risk areas (probability > 0.8) of O. volvulus infection were all parts of Odeda, Abeokuta South, and Abeokuta North, southern part of Imeko-Afon, a large part of Yewa North, some parts of Ewekoro and Obafemi-Owode LGAs. The estimated prevalence for these regions were >60% (between 61% and 100%). As predicted, O. volvulus occurrence showed a positive association with variables reflecting precipitation in Ogun State. Our predictive risk-maps has provided useful information for the elimination of onchocerciais, by identifying priority areas for delivery of intervention in Ogun State, Nigeria.

Development of sustainable technology to treat domestic wastewater with added advantages of cost reduction and improved handling efficiency is crucial in developing countries. This is because, domestic wastewater from households are stored in septic tanks and are poorly treated prior discharge. This study developed a macrophyte-assisted vermifiltration (MAV) system to treat domestic wastewater. The MAV system is an integrated approach of macrophytes and earthworms in a vermifiltration and complex physicochemical mechanism processes. The use of different macrophyte and earthworm species was hypothesized by the study to affect and vary the treatment performance of the developed MAV. The study therefore aimed to evaluate the treatment performance of the developed MAV when three varied macrophyte species (Eichhornia crassopes, Pistia stratiotes and Spirodela sp.) and two varied earthworm species (Eisenia fetida and Eudrilus eugeniae) were used to design the treatment system. Treated effluents were collected every 48hours within two weeks for physico-chemical, pathogen and helminth analysis. The contaminants (Ntot, NH3, NO3-N and Ptot) in the wastewater were high (>50 mgL-1, >5 mgL-1, >1 mgL-1 and >20 mgL-1 respectively). Results revealed that the developed MAV systems were effective in the removal of solids (>60%), nutrients (>60%) and pathogens (>90%). In most cases, there were no significant differences between the selected varied macrophytes and earthworms in the treatment performances. Results therefore demonstrated that the selected macrophytes combined with the earthworm species were suitable when used in the development of the MAV system. Developing the MAV with the selected varied macrophyte and earthworm species did not only contribute to the treatment of the wastewater, but also improved the vermiculture. Eudrilus eugeniae however demonstrated higher biomass gain (5–10% more) compared to Eisenia fetida.
Practice environment determinants of job satisfaction among midwives at healthcare facilities in Accra Metropolis: A multicentre study

Introduction

Sustainable Development Goal 3 (SDG 3) has been one of the key goals for all partners of health globally. The health workforce especially midwives are among the principal skilled experts for achieving the goal. This is evidenced in the role they play in caring for pregnant women from the antenatal stages to the postpartum periods. However, very little has been reported about midwives’ job satisfaction in Ghana. The study assessed the practice environment determinants of job satisfaction among registered midwives in Ghana.

Materials and methods

A cross-sectional design was adopted to recruit midwives from public and quasi-government hospitals in Accra Metropolis. Validated scales—‘Measure of Job Satisfaction’ and ‘Practice Environment Scale of Nursing Work Index’ were used for data collection. Data was analysed through descriptive statistics, Pearson correlation and linear regression.

Results

Midwives had a positive perception of their work environment. They were generally satisfied with their job but were dissatisfied with their salaries. Key determinants of midwives’ job satisfaction included years of work as a midwife, managers’ leadership and support, and adequacy of human and material resources.

Conclusion

Improving midwives’ job satisfaction through enabling the work environment will go a long way to improve healthcare provision in the healthcare delivery points in helping achieve SDG 3.
Thymoquinone effect on the Dictyostelium discoideum model correlates with functional roles for glutathione S-transferases in eukaryotic proliferation, chemotaxis, and development

Published: March 2023

An increasing body of literature demonstrates the therapeutic relevance of polyphenols in eukaryotic cell and animal model studies. The phase II glutathione S-transferases (GST) show differential responses to thymoquinone, a major bioactive polyphenol constituent of the black seed, Nigella sativa. Beyond antioxidant defense, GSTs may act in non-enzymatic capacities to effect cell cycle, motility, and differentiation. Here, we report the impact of thymoquinone on the life cycle of the eukaryotic model Dictyostelium discoideum and accompanying profiles of its GST-alpha (DdGSTA) enzyme activity and isozyme expression. In silico molecular modeling revealed strong interaction(s) between thymoquinone and DdGSTA2 and DdGSTA3 isozymes that correlated with in vivo, dose-dependent inhibition of cell proliferation of amoebae at 24, 48, and 72hr. Similarly, cytosolic DdGST enzyme activity (CDNB activity) was also responsive to different thymoquinone concentrations. Thymoquinone generally reduced expression of DdGSTA2 and DdGSTA3 isozymes in proliferating cells, however differential expression of the isozymes occurred during starvation. Thymoquinone effectively reduced early-stage aggregation of starved amoeba, accompanied by increased reactive oxygen species and altered expression of tubulin and contact site A (gp80), which resulted in reduced morphogenesis and fruiting body formation. These observations reveal that thymoquinone can impact signaling mechanisms that regulate proliferation and development in D. discoideum.

Published: March 2023

Apresenta-se, neste artigo, uma análise inicial de estudos estatísticos aplicados aos métodos geográficos. Busca-se atender a demanda de análises em promoção da saúde pública e, em especial, investigar a transmissão da Covid-19 na Mesorregião Sul/Sudoeste do estado de Minas Gerais, no período de março de 2020 a março de 2021. A relação entre a Estatística descritiva e a Geografia é extremamente importante quando se lida com epidemiologia. A Covid-19 trouxe debates que colocaram em destaque o uso dessas ferramentas como fundamentais para a elaboração de estratégias e planejamento frente à pandemia do SARS-COV-2. O objetivo deste artigo é engajar pesquisadores na atenção e na operacionalização de dados espaciais como elementos fundamentais para as estratégias de planejamento. A partir da contextualização dos conceitos e da consideração dos problemas inerentes aos usos da estatística para análise espacial da Covid-19, serão construídas as potencialidades da estatística como aliada à epidemiologia. Para tanto, foram analisados os dados correspondentes aos processos de difusão e distribuição da Covid-19 a partir da hipótese de interiorização da contaminação da doença na Mesorregião em estudo.

Este artigo apresenta uma proposta de processo analítico para pesquisas de revisão bibliográfica com foco na compreensão de marcos temáticos e de fundamentação teórica. Especificamente foi analisado determinado eixo epistêmico, a saber, o pós-estruturalismo, buscando-se identificar quantidades, fluxos e recorrências das balizas de fundamentação conceituais e temáticas estudadas, com desdobramentos para uma análise do modo como esse retrato se reflete no recorte temático específico (Geografia). Para isso, empreendeu-se um percurso analítico composto pelo arranjo metodológico embasado em Análise de Conteúdo, Análise de Agrupamento de Dados (Cluster Analysis) e na Teoria Fundamentada em Dados (Grounded Theory). A partir desse processo a pesquisa apresenta um fluxograma de procedimentos (modelo de processo analítico), uma série de dados configurados em gráficos (de barras, “caixa-bigode”, histograma e explosão solar), quadros, nuvem de palavras, ficha analítica (modelo de processo analítico), Diagrama de Sankey e mindmap (modelo de processo analítico). A pesquisa foi concluída com a elaboração de problematizações e/ou proposições, no intuito de criar um horizonte de possibilidades para novas pesquisas, com a expectativa de que essa proposta, dado o seu caráter aberto e processual, seja não somente utilizada em outros estudos, mas, sobretudo, aprimorada e continuada.
