Hypothetical mistakes: hedging wrong answers with conditional language in initiation-response-evaluation (IRE) sequences in an American high school classroom
Authors: Chandras Jessica Sujata 
Published: December 2023

Abstract
This article analyzes American high school students hedging incorrect responses to teacher-initiated questions in IRE (Initiation-Response-Evaluation) format using conditional language and hypotheticals in ways that facilitate an affiliative stance between students and their teacher. Scholarship on hedging details its use to approximate responses as a shield against doubt and criticism or as collaborative communication, whereas stance is a grammatically encompassed expression of attitudes related to the content of a message. This study brings together theories of stance, hedging, and conditional language use to outline how errors can be a student-initiated pedagogical tool to deepen explanations and engagement. To broaden understanding of the form and function of both incorrect answers and hedging as a structure expanding traditional IRE turntaking for managing classroom discourse, this article outlines seven examples total where students hedge what they know to be incorrect answers drawn from recordings made in forty, fifty-minute high school level Latin lessons over the 2019–2020 academic year. This study presents a model and impacts of students creatively reconfiguring evaluative responses along with their teacher during instruction through hedging incorrect information in conditional, and sometimes hypothetical, formats.

Published: December 2023

Abstract
This article presents a compact implantable antenna for biomedical use in the ISM band (2.4–2.48 GHz). The antenna is designed with Roger RT/duroid 6010.2LM high permittivity substrate of thickness 0.25 mm, and feed with a 50 Ω co-axial feed. A hybrid-loop resonator slot structure and C & I-shaped slots in the radiating patch has enabled the antenna to work in the ISM band. Via less ground makes this design simple, easier to fabricate, and a suitable candidate for implantable application. The proposed antenna occupies a small volume of 0.0984 λ
0 × 0.082 λ
0 × 0.00468 λ
0 and retained 152 MHz bandwidth (2.4077–2.5599 GHz with FBW 7.64 %) with a maximum gain of −22 dBi where λ
0 is guided wavelength. The projected antenna has good performance in the multi-layer tissue model, male human head voxel model, frequency-dependent skin model, and in muscle phantom by maintaining a minimum −20 dB return-loss in the ISM band. The proposed antenna’s Device Integration using a frequency-dependent skin phantom was performed and the results are well-suited for biomedical applications in the ISM band. The bare antenna was used to study the Specific Absorption Rate (SAR) in the human scalp. Where for 1 g and 10 g tissues the investigated results are 626.05 W/kg and 84.4 W/kg for an input power of 1 W, however the input power is limited to maximum 2.55 mW (for 1 g tissue) and 23.56 mW (for 10 g tissue) to comply with IEEE SAR guidelines. The qualities of the manufactured antenna are verified in a skin-imitating gel and animal tissue that exhibits good agreement with the simulation outcomes.

Published: December 2023

Abstract
We construct a Financial Conditions Index (FCI) for the United States using a dataset that features many missing observations. The novel combination of probabilistic principal component techniques and a Bayesian factor-augmented VAR model resolves the challenges posed by data points being unavailable within a high-frequency dataset. Even with up to 62 % of the data missing, the new approach yields a less noisy FCI that tracks the movement of 22 underlying financial variables more accurately both in-sample and out-of-sample.

Published: December 2023

OBJECTIVES
With this study, we aim to describe transgender and nonbinary adolescents and young adults’ stated gender treatment goals at the time of initial presentation to medical care.

METHODS
This is a retrospective chart review of transgender and nonbinary patients aged 10 to 24 seeking specific gender-affirming health care. Charts were reviewed for specifically stated goals of future hormonal or surgical care for gender and analyzed by the experienced or asserted gender (man, woman, nonbinary, eclectic) of participants.

RESULTS
In total, 176 patient encounters were reviewed. Of these, 71% were assigned female at birth. Most participants experienced a masculine gender (46.6%), identified as white (65.3%), and had private health insurance (73.3%). Most patients had a goal of initiating hormone therapy (97.4%) and eventual surgery (87.1%). Of those who had a surgical goal, most (87.5%) desired surgery of the chest or breast, and a minority (29.3%) desired eventual genital surgery. The second-largest gender group was patients who either declined to state an asserted gender or felt unable to describe their gender experience (eclectic, 23.3%), and this group’s treatment goals did not mirror any other group’s goals.

CONCLUSIONS
At the time of initial presentation to medical care for gender-specific needs, many adolescents are capable of asserting specific treatment goals. Most do not desire genital surgery. A large minority of patients decline to state an asserted gender or feel unable to assert a specific gender, and this population appears distinct from more traditional genders in terms of treatment goals.

This study aimed to examine the impact of the 5Es (Engagement, Exploration, Explanation, Elaboration, and Evaluation) instructional strategy on secondary school chemistry students' academic achievement in Calabar, Nigeria. A quasi-experimental design was adopted for this study. The population comprised 2,350 Secondary School (SSII) chemistry students drawn from the Calabar Education Zone, Nigeria, from which a sample of 240 students was identified through proportionate stratified random and judgmental sampling techniques. The data was collected through an instrument called ‘’chemistry achievement test’’ (CAT). Two research hypotheses were stated to direct the study. Data obtained were analyzed using the analysis of Covariance and Multiple Classifications Analysis. Results indicated that learners tutored with 5Es instructional strategy enhanced academic achievement more than those tutored using the conventional method. However, students' gender did not make any impact on their achievement when tutored with 5Es instructional strategy and lecture method. It was concluded that the utilization of inquiring and critical thinking skills when students were tutored using the 5ES instructional strategy would be responsible for their high achievement. It was recommended that the introduction of the 5Es instructional strategy should be implemented from the basic primary science to build the younger scientist minds into more creative, goal-oriented, problem-solving individuals.

Objective: Urolithiasis is responsible for the majority of urological emergencies. Although computed tomography (CT) scan can identify urinary obstruction caused by stones, there is a growing concern about exposure to radiation made by this method. Renal scintigraphy can provide valuable insights regarding the functional status of kidneys and can significantly reduce exposure to radiation.
The goal of present study was to assess renal function through renal scintigraphy in patients with acute renal colic and it explores the association between renal scintigraphy performance and ultrasound in terms of detecting hydronephrosis.
Methods: For this study, 20 patients with acute renal colic were chosen. Each patient underwent renal ultrasonography and subsequently received renal scintigraphy with Technetium-99m diethylenetriaminepentaacetic acid (Tc-99m DTPA). Cohen's Kappa coefficient and Cramer's V correlation were employed to demonstrate the extent of agreement between ultrasound and renal scintigraphy.
Results: 12 (60%) patients were male. Glomerular filtration rate (GFR) values were correlated with Cockcroft-Gault equation and the Gates method (P=0.002, r=0.642). There was a good agreement and a statistically significant relationship between ultrasound and renal scintigraphy in terms of detecting obstructive uropathy in both kidneys.
Conclusion: To conclude, GFR values were correlated between Cockcroft-Gault equation and the Gates method in patients with acute renal colic. There was a good agreement and statistically significant relationship between ultrasound and obstructive renography results in both kidneys. However, we found no association between perfusion phase of renal scintigraphy and ultrasonography in terms of hydronephrosis detection.

Published: December 2023

Objective: Coronavirus Disease 2019 (COVID-19)-related mortality includes several risk variables that are country-specific in nature. The development of a scoring system is necessary regarding the appearance of novel virus variants. The objective of this research is to develop a prognostic score for COVID-19 patients in resource-constrained settings.

Methods: This study used a retrospective and prospective cohort design to identify variables that influence COVID-19 patients' in-hospital mortality. The receiver operating characteristic (ROC) curve analysis was utilized to determine the laboratory variables cut-off. Cox regression analysis was undertaken to determine the exact variables influencing the survival of COVID-19 patients. A scoring system was created using the best model based on the Hosmer-Lemeshow test (calibration) and the area under the curve (AUC) (discrimination ability).

Results: Based on calibration and discrimination testing, model 2 (immune disorders, unconsciousness, cerebrovascular disease, onset, and oxygen saturation) was rated as the most advantageous model. Model 2 (without age adjustment) had a superior AUC than model 2A (with age). Cut-off was determined at 2, and calculated for onset ≥7 days (AUC=0.816, 95% CI: 0.742,0.890) and <7 days (AUC=0.850, 95% CI: 0.784,0.916). There was no difference in scoring system utilization for subjects recruited during Delta or Omicron waves (P=0.527).

Conclusion: The model (cut-off value ≥2) which incorporated age ≥65 years, immune disorders, decreased consciousness, increased respiratory rate, and oxygen saturation <95% is the best model in our study to predict COVID-19 patient mortality.

Authors: Park Kiduk 
Published: December 2023

Background:The HOPE VI program was initiated to transform public housing and improve the lives of low-income households. Its effectiveness in achieving these goals remains a subject of debate, necessitating a comprehensive review of its impact.Objective:This study aims to evaluate the influence of the HOPE VI program on various social outcomes for low-income households, particularly focusing on the effects of relocation to potentially more favorable residential areas.Methods:The study employs a literature review methodology, analyzing a range of scholarly works, including peer-reviewed articles and relevant project reports. It assesses the impact of the HOPE VI program on the quality of life of relocates and examines the relationship between residential environmental changes and the effectiveness of relocation interventions.Findings:The review reveals a complex picture of the HOPE VI program’s impact. While some low-income families benefit from improved living conditions and neighborhood environments, others face challenges adapting to new communities. The study highlights the importance of subjective people–place relationships, revealing that emotional attachments to neighborhoods play a crucial role in the success of relocation efforts.Conclusions:The findings underscore the need for policymakers to consider the emotional connections residents have with their neighborhoods. A deeper understanding of these relationships can inform better-designed interventions that support low-income households in adjusting to new residential areas, ultimately leading to more effective and humane housing policies.

Published: December 2023

The article is devoted to the methodology for determining the parameters of the kernels of the transverse creep of the linear-viscosity materials for the minds of a folding stressed frame. Issues: One of the main tasks in the theory of viscosity is the task of choosing the structure of the kernel of decay and the assignment of parameters of the kernels. The task is actual, shards of the correct designation of unknown parameters in the present to lay down the terms of operation of structural elements.Purpose: The method of work is the development of the method of assigning the parameters of the kernels of transverse creep and the approbation of the results on the problems of analysis of the deformation of transverse creep. Implementation methodology: If the given methodology is only valid for linear materials, then at the first stage, linearity in viscous powers is entrenched. The parameters of the kernels are significant on the basis of the hypothesis of a single function of creep, the basis of which is presented in a confidence interval of 10%. In the capacity of the core of the decay of the vicorist, there is a shot-exponential kernel. The task is to reduce to the minimization of the functionality of the quadratic adjustment of the experimental data in the species of rozrachunks. On the basis of the results, it is possible to create a conclusions about the practicality of the induced technique, both for "Plaxiglass ST-1" and for other linear materials. The maximum allowance for calculation data from experimental warehouses is 5%.

Published: December 2023

Abstract
The Thar desert constitutes a unique ecosystem in India which supports distinct fauna adapted to it. But there is only limited information about the diversity of spiders in this area. A survey on spider fauna of the Thar desert of Rajasthan was conducted using collection methods like ground collection, aerial sampling, beating and litter sampling. Alpha diversity parameters such as indices, richness and abundance was also measured. Effect of seasons on spider population was also evaluated. This study revealed the presence of 127 species of spiders belonging to 61 genera and 17 families from the Thar desert. Maximum Shannon index was during summer and Simpson index during monsoon. Highest species richness was noticed during monsoon while abundance was higher during winter. This study reveals that the Thar desert ecosystem supports a variety of habitats facing species loss due to anthropogenic disturbances and the information on indicator species like spiders can be used for conservation planning for the native fauna.
An Investigation into Employees’ Factors of Flexible Working Hours (FWH) for Productivity in Saudi: A Qualitative Triangulation
Authors: Mohiya Mohamed 
Published: December 2023

Abstract

Background One of the most controversial HRM topics that has received extensive attention from academics and practitioners communities over the past two decades is Flexible Working Hours (FWH) and its impact on productivity. Nevertheless, the work is mostly focused on business and organizational aspects neglecting the employees’ health perspectives. Most importantly, there is a lack of a strong theoretical foundation. Thus, unlike other work, the present study focuses heavily on the employees’ perspective based on a theory; namely: Social Exchange Theory (SET). SET is valuable because it magnifies the importance of the employee as a partner who is in reciprocal social relations. This study aims to explore and evaluate the antecedents of FWH, mainly: employees’ health-related factors, which affect their productivity. Key major concepts to emerge from the literature analysis are brought together, and grouped under mindfulness/well-being. Methods Two triangulated sets of qualitative data were collected, namely: semi-structured interviews and document analysis (cross-sectional and longitudinal). Thirty-two interviews were conducted with employees and with management. Document analysis is a novel source of data that was extracted from the company’s internal technological platform and contains employees’ first-hand computerized typewritten comments about FWH. Results The adopted qualitative triangulated methods assist in interrogation to allow other undiscovered factors to emerge from the analysis of the data which are grouped as sub-themes under quality of time, namely: mid-break, morning and evening person, sleeping and tardiness, and social life. The most significant factors found affecting employees’ decision to demand FWH for productivity are midday breaks, traffic/transportation, and schooling. Conclusions The finding reveals that HR practitioners need to recognize employees’ health and social factors before applying FWH practice. This research lies in the fact that it is one of the first HR health studies to contribute to advancing theoretical and empirical knowledge, particularly in Saudi Arabia. Based on findings from this empirical inquiry, this present research makes an original and important contribution to HR health scholarship and reflects theoretical rigor (Social Exchange Theory), methodological (triangulation methods), empirical, and practical. For example, theoretical contributions regarding SET’s reciprocity “black box” were highlighted.
Research on Automatic Generation Technology of Double Helix Shaped conformal cooling channels for Injection Mold

Published: December 2023

Abstract

The conformal cooling channel is more and more favored by the mold enterprises because of its excellent cooling performance. However, the current design of conformal cooling channel generally has the problems of complex, time-consuming and error prone design process. The spiral cooling channel is a very important cooling channel structure in injection mold, and its application is extremely common in practical mold engineering cases. For a long time, designers have had to rely on manual construction of spiral cooling channel, which is a cumbersome and inefficient design process. Inspired by the spring structure and based on the design characteristics of spiral cooling channel, this paper puts forward an automatic generation method of conformal cooling channel based on the basic requirements of conformal cooling channel design in engineering practice. The basic idea of this method firstly is to generate the initial trajectory lines and store them in a list in the specified order. Then, based on the initial trajectory line as the basic geometry, a series of control points are generated, and all control points, including the inlet and outlet coordinate points, are sorted. Finally, generate a spline curve based on the control points and scan along the spline curve with the specified cross-section to form cooling channels. Experimental results show that this method can significantly decrease the time of design and guide users to quickly complete the design, while reducing design errors to improve working efficiency.
Analysis of bamboo fibres and their associated dye in the parasite-host dynamics of freshwater fish

Published: December 2023

Abstract

With the growth of the fashion and textile industries into the 21st Century, associated pollution has become pervasive. Of these pollutants, fibre-based microplastics are the most common types of plastics recovered from aquatic ecosystems encouraging the increased trend in organic fibre usage. Often marketed as biodegradable and ‘environmentally friendly’, organic textile fibres are seen as less harmful. Here, we assess the health effects of reconstituted bamboo viscose fibres, processed bamboo-elastane fibres (both at 700 fibres/L) and their associated dye (Reactive Black-5, at 1 mg/L) on fish, with an emphasis on disease resistance utilising an established host-parasite system: the freshwater guppy host (Poecilia reticulata) and Gyrodactylus turnbulli (monogenean ectoparasite). Following three weeks exposure to the bamboo fibres and associate dye, half the experimental fish were infected with G. turnbulli, after which individual parasite trajectories were monitored for a further 17 days. Overall, exposure to reconstituted bamboo-viscose fibres, processed bamboo-elastane fibres or dye were not associated with any change in host mortality nor any significant changes in parasite infection burdens. When analysing the routine metabolic rate (RMR) of fish, we noted that uninfected fish had, on average, significantly impacted RMR when exposed to processed bamboo elastane (increased RMR) and reconstituted bamboo viscose (decreased RMR). Hosts exposed to reconstituted bamboo viscose and the associated dye treatment showed significant changes in RMR pre- and post-infection. This study bolsters the growing and needed assessment of the potential environmental impacts of alternative non-plastic fibres; nevertheless, more research is needed in this field to prevent potential greenwashing.
