Spanish Preservice Primary School Teachers’ Understanding of the Tides Phenomenon
Authors: Armario María , Oliva José María , Jiménez-Tenorio Natalia 
Published: September 2021

AbstractIn this study, we analyzed the descriptive knowledge and mental models of the phenomenon of tides manifested by 111 preservice primary teachers. The instrument employed is an open-ended questionnaire, analyzed by means of an approach that explores the descriptions, explanations, and predictions in respect of this phenomenon by our subjects. First, we made a descriptive study of the kinds of ideas applied across different dimensions of analysis, and, subsequently, a cluster analysis was performed to check how those ideas were articulated and modeled. By means of this analysis, we were able to identify the mental models underlying the responses of preservice primary teachers. Furthermore, the results showed that the models they did have were not used when it came to making predictions in local situations. Instead, they employed heuristic rules based on everyday assumptions, not always consistent with tidal cycles of approximately 12 h. However, faced with situations that required thinking on a global scale, they did use their models, normally based on alternative conceptions. Lastly, from the results obtained, we consider some of the possible difficulties that preservice primary teachers may have in learning about the phenomenon of tides, and the implications for future teaching–learning designs aimed at overcoming those difficulties.

Authors: Reitan Kjell Inge , Øie Gunvor , Jørgensen Håvard , Wang Xinxin 
Published: September 2021

AbstractMarine microalgae are a promising sustainable source of lipids, omega-3 fatty acids, and carbohydrates. Selected microalgae species belonging to the Bacillariophyceae, Haptophyceae, Eustigmatophyceae, and Prasinophyceae were characterised for cellular content of carbon and nitrogen, and for production yields of lipids, fatty acids, total carbohydrates, and β-glucans. Carbon and nitrogen content showed a hyperbolic decrease with increasing cell numbers for Chaetoceros calcitrans, C. muelleri, Skeletonema costatum, Tetraselmis sp., and Nannochloropsis oculata. Cultures of Pavlova lutheri and Tisochrysis lutea showed an increase in carbon content per cell, but a decrease in nitrogen content. The total lipid content of C. muelleri, C. calcitrans, N. oculata, and T. lutea increased with decreasing relative growth rate; however, the highest productivity of lipids was found in T. lutea grown at 40% of the maximum specific growth rate. The highest content of eicosapentaenoic acid was found in C. muelleri, C. calcitrans, and N. oculata, and the highest content of docosahexaenoic acid was found in T. lutea. The β-glucan fraction of the carbohydrates was highest in C. muelleri and C. calcitrans and was very low in N. oculata. Out of the species investigated, C. muelleri had the highest production yield of β-glucans, obtained when cultivated at a 40% relative growth rate.
Minimizing the makespan on a single machine subject to modular setups
Authors: Briskorn Dirk , Stephan Konrad , Boysen Nils 
Published: September 2021

AbstractSingle machine scheduling with sequence-dependent setup times is one of the classical problems of production planning with widespread applications in many industries. Solving this problem under the min-makespan objective is well known to be strongly NP-hard. We consider a special case of the problem arising from products having a modular design. This means that product characteristics, (mass-)customizable by customers, are realized by separate components that can freely be combined. If consecutive products differ by a component, then a setup is necessary. This results in a specially structured setup matrix that depends on the similarities of product characteristics. We differentiate alternative problem cases where, for instance, the setup operations for multiple components either have to be executed sequentially or are allowed to be conducted in parallel. We analyze the computational complexity of various problem settings. Our findings reveal some special cases that are solvable in polynomial time, whereas most problem settings are shown to remain strongly NP-hard.
“When I think of mental healthcare, I think of no care.” Mental Health Services as a Vital Component of Prenatal Care for Black Women

Published: September 2021

Abstract
Purpose
Black people give birth joyously despite disproportionate rates of adverse perinatal outcomes. Given that group prenatal care shows promise in mitigating these inequities, we sought to solicit the opinions of Black peripartum women on how group prenatal care could be tailored to fit their specific needs. In this study, we describe attitudes about a proposed Black group prenatal care in a single focus group of 11 Black women who receive maternal health services from Black Infant Health (BIH, a state and federal funded state-wide program for Black pregnant people with the goal to improve infant and maternal health). These data were used to design a race-conscious group prenatal care curriculum specifically for Black women at UCSF.

Description
This study was an analysis of focus group data generated as part of a larger project focused on community involvement in Black maternal health. English speaking pregnant or recently postpartum women age 18 or older who receive services from BIH were recruited to participated in the focus group analyzed in this study. All facilitators of the focus group were Black women in order to facilitate candid conversation about racism in prenatal care.

Assessment
The need for mental health care was common thread underlying all conversations about prenatal health improvements desired by our focus groups. Participants expressed the centrality of mental health access during our discussion of other themes (e.g.: ease of access, inclusion of partners, special classes for teen moms) by discussing them in terms of their relationship to mental health. Our participants’ clear expression of the centrality of mental health care to their prenatal health guided our decision to focus on mental health as a necessary pillar of any group prenatal care intervention designed to mitigate perinatal healthcare disparities in this paper. Three themes related to mental health integration into group prenatal care emerged from thematic analysis of the transcripts. Participants expressed insufficient access and advocacy, and provider distrust.

Conclusion
Evidence exists supporting group prenatal care as a tool for mitigation of perinatal health disparities among Black women. There is also a large body of data describing the disproportionate burden of mental health needs among Black women. The rich data we present here from Black women on their desire for the integration of these two needs fits well into the parallel conversation occurring in the literature. To our knowledge, this is the first study investigating desires of Black women regarding group prenatal care designed specifically for them. They expressed a strong desire for more access to mental health care providers who are racially conscious and aware of white supremacy, and nuanced opinions on the role of racial concordance in health equity.
Posttraumatic growth and well-being among people living with HIV: A systematic review and meta-analysis in recognition of 40 years of HIV/AIDS
Authors: Pięta Małgorzata , Rzeszutek Marcin 
Published: September 2021

Abstract
Objectives
This systematic review and meta-analysis aimed to synthesize, analyze, and critically review existing studies on the relationship between posttraumatic growth (PTG) and psychological well-being (operationalized either via positive or negative well-being indicators) among people living with HIV (PLWH). We also investigated whether this association varies as a function of socio-demographic, clinical characteristics, and study publication year.

Method
We conducted a structured literature search on Web of Science, Scopus, MedLine, PsyARTICLES, ProQuest, and Google Scholar. The most important inclusion criteria encompassed quantitative and peer-reviewed articles published in English.

Results
After selection, we accepted 27 articles for further analysis (N = 6333 participants). Eight studies used positive indicators of well-being. The other 19 studies focused on negative indicators of well-being. Meta-analysis revealed that there was a negative weak-size association between PTG and negative well-being indicators (r = − 0.18, 95% CI [− 0.23; − 0.11]) and a positive medium-size association between PTG and positive well-being measures (r = 0.35, 95% CI [0.21; 0.47]). We detected no moderators.

Conclusions
The present meta-analysis and systematic review revealed expected negative and positive associations between PTG and negative versus positive well-being indicators among PLWH. Specifically, the relationship between PTG and positive well-being indicators was more substantial than the link between PTG and negative well-being measures in these patients. Finally, observed high heterogeneity between studies and several measurement problems call for significant modification and improvement of PTG research among PLWH.
Why invent the handle? Electromyography (EMG) and efficiency of use data investigating the prehistoric origin and selection of hafted stone knives

Published: September 2021

AbstractFor over 3 million years hominins held stone-cutting tools in the hand, gripping the portion of tool displaying a sharp cutting edge directly. During the late Middle Pleistocene human populations started to produce hafted composite knives, where the stone element displaying a sharp cutting edge was secured in a handle. Prevailing archaeological literature suggests that handles convey benefits to tool users by increasing cutting performance and reducing musculoskeletal stresses, yet to date these hypotheses remain largely untested. Here, we compare the cutting performance of hafted knives, ‘basic’ flake tools, and large bifacial tools during two standardized cutting tasks. Going further, we examine the comparative ergonomics of each tool type through electromyographic (EMG) analysis of nine upper limb muscles. Results suggest that knives (1) recruit muscles responsible for digit flexion (i.e. gripping) and in-hand manipulation relatively less than alternative stone tool types and (2) may convey functional performance benefits relative to unhafted stone tool alternatives when considered as a generalised cutting tool. Furthermore, our data indicate that knives facilitate greater muscle activity in the upper arm and forearm, potentially resulting in the application of greater cutting forces during tool use. Compared to unhafted prehistoric alternatives, hafted stone knives demonstrate increased ergonomic properties and some functional performance benefits. These factors would likely have contributed to the invention and widespread adoption of hafted stone knives during the late Middle Pleistocene.

Authors: Xiao Shan , Yang Ye , Liu Yuetong , Zhu Jun 
Published: September 2021

AbstractPurposeThe aim of this study is to explore the effects of liraglutide (LRG) on the expression of FTO, AMPK, and AKT in the visceral adipose tissues of obese and diabetic rats and the underlying mechanisms thereof.MethodsThirty SPF-grade, male SD rats were randomly divided into the healthy control, diabetic model (DM), and DM + LRG groups. The DM and DM + LRG groups were administered normal saline and LRG (0.6 mg/kg/d), respectively. After 12 weeks, the body weight of the rats was measured, and their visceral adipose tissues were collected and weighed; the levels of serum biochemical indicators and FTO, AMPK, and AKT in these tissues were then measured using qRT-PCR and western blotting.ResultsCompared to the control group, the body weight and visceral fat accumulation and blood glucose, TG, TC, and LDL-C levels increased significantly, while the HDL-C levels decreased significantly, in the DM group (p < 0.05). After LRG treatment, the HDL-C levels increased significantly, but the levels of the other indicators decreased significantly (p < 0.05). Compared to the control group, the visceral adipose tissue levels of FTO and AKT increased significantly, while the AMPK levels decreased significantly in the DM group (p < 0.05). After LRG treatment, the FTO and AKT levels decreased significantly, and the AMPK levels increased significantly (p < 0.05).ConclusionLRG may activate and inhibit the AMPK and AKT pathways, respectively, and decrease FTO expression, thereby alleviating abdominal obesity in type 2 diabetes.

Abstract
Aim
This study investigated the effects of sodium-glucose cotransporter 2 (SGLT2) inhibitors on renal outcomes in Asian patients with type 2 diabetes mellitus (T2DM).

Materials and methods
We searched Medline, EMBASE, and the Cochrane Library to identify randomized controlled trials published up to April 2020 that compared SGLT2 inhibitors with placebo or active comparator and reported any renal outcomes in Asian patients with T2DM. Random effects models and inverse variance weighting were used to calculate relative risks with 95% confidence intervals (CIs).

Results
We included 14 studies, totaling 3792 patients, in the analysis. In the short term, SGLT2 inhibitors significantly slowed estimated glomerular filtration rate (eGFR) decline (MD: 0.80; 95% CI: 0.66 to 0.94; p < 0.00001) and reduced Scr levels (SMD: − 0.17; 95% CI: − 0.23 to − 0.10; p < 0.00001) as compared with the control groups. The SGLT2 inhibitor group also had an advantage over the control group in lowering uric acid (UA) (SMD: − 1.2; 95% CI: − 1.30 to − 1.11; p < 0.00001). There was no significant difference in urinary albumin creatinine ratio (UACR) reduction between the SGLT2 inhibitor and control groups (MD: − 8.87; 95% CI: − 19.80 to 2.06; p = 0.11). However, dapagliflozin does appear to reduce albuminuria (p = 0.005). Lastly, SGLT2 inhibitors increased the incidence of adverse events (AEs) related to renal function (OR: 1.90; 95% CI: 1.24 to 2.91; p = 0.003), but did not increase the incidence of renal impairment (OR: 0.85; 95% CI: 0.40 to 1.81; p = 0.68).

Conclusion
The use of SGLT2 inhibitors in Asian patients with T2DM can help delay the decline of eGFR and reduce Scr and UA. Although SGLT2 inhibitors have no overall advantage in reducing albuminuria, dapagliflozin does appear to reduce albuminuria, and while they may increase the occurrence of AEs related to renal function, they do not increase the incidence of renal impairment.

AbstractIt is of great importance to explore a creative route to improve the degradation efficiency of organic pollutants in wastewater. Herein, we construct a unique hybrid system by combining self-powered triboelectric nanogenerator (TENG) with carbon dots-TiO2 sheets doped three-dimensional graphene oxide photocatalyst (3DGA@CDs-TNs), which can significantly enhance the degradation efficiency of brilliant green (BG) and direct blue 5B (DB) owing to the powerful interaction of TENG and 3DGA@CDs-TNs photocatalyst. The power output of TENG can be applied for wastewater purification directly, which exhibits a self-powered electrocatalytic technology. Furthermore, the results also verify that TENG can replace conventional electric catalyst to remove pollutants effectively from wastewater without any consumption. Subsequently, the unstable fragments and the plausible removal pathways of the two pollutants are proposed. Our work sheds light on the development of efficient and sustainable TENG/photocatalyst system, opening up new opportunities and possibilities for comprehensive utilization of random energy.

Hidden Markov Models of Evidence Accumulation in Speeded Decision Tasks
Authors: Kucharský Šimon , Tran N.-Han , Veldkamp Karel , Raijmakers Maartje , Visser Ingmar 
Published: September 2021

AbstractSpeeded decision tasks are usually modeled within the evidence accumulation framework, enabling inferences on latent cognitive parameters, and capturing dependencies between the observed response times and accuracy. An example is the speed-accuracy trade-off, where people sacrifice speed for accuracy (or vice versa). Different views on this phenomenon lead to the idea that participants may not be able to control this trade-off on a continuum, but rather switch between distinct states (Dutilh et al.,Cognitive Science35(2):211–250, 2010). Hidden Markov models are used to account for switching between distinct states. However, combining evidence accumulation models with a hidden Markov structure is a challenging problem, as evidence accumulation models typically come with identification and computational issues that make them challenging on their own. Thus, an integration of hidden Markov models with evidence accumulation models has still remained elusive, even though such models would allow researchers to capture potential dependencies between response times and accuracy within the states, while concomitantly capturing different behavioral modes during cognitive processing. This article presents a model that uses an evidence accumulation model as part of a hidden Markov structure. This model is considered as a proof of principle that evidence accumulation models can be combined with Markov switching models. As such, the article considers a very simple case of a simplified Linear Ballistic Accumulation. An extensive simulation study was conducted to validate the model’s implementation according to principles of robust Bayesian workflow. Example reanalysis of data from Dutilh et al. (Cognitive Science35(2):211–250, 2010) demonstrates the application of the new model. The article concludes with limitations and future extensions or alternatives to the model and its application.
The oscillatory longwave Marangoni convection in a thin film heated from below
Authors: Samoilova Anna , Nepomnyashchy Alexander 
Published: September 2021

AbstractA novel type of Marangoni convection was predicted theoretically a decade ago. The thin liquid film atop a substrate of low thermal conductivity was considered. In the case of heating from below, the Marangoni convection emerges not only in a conventional stationary regime, but also as oscillatory flows. Specifically, the oscillatory Marangoni convection emerges if (1) the heat flux from the free surface is small, and (2) the large-scale deformation of the free surface is allowed. During the past decade, this novel Marangoni convection was detected and investigated in several other theoretical works. The review discusses the recent achievements in studying the oscillatory Marangoni convection in a thin film heated from below. The guiding data for observation of the oscillatory regime are also provided.
Passive solar dryers as sustainable alternatives for drying agricultural produce in sub-Saharan Africa: advances and challenges

Published: September 2021

AbstractThe lack of adequate techniques for food processing is among the reasons underlying food losses and high levels of hunger in Sub-Saharan Africa; the application of solar energy to dry agricultural products is one potential solution. However, the total replacement of traditional uses of solar energy is still far from reality. Therefore, in this study, we systematically review the academic literature testing passive solar drying systems in order to assess their performance. Then the main limitations and challenges for passive solar dryers developed in Sub-Saharan Africa are derived. The literature search reveals very limited research and a lack of standardized methods to assess solar dryer performance. Studies mainly report parameters related to dryers’ thermal performance and physical features, thus neglecting parameters related to the quality of dried products and economics. Standardized and robust methodologies are urgently needed for more accurate conclusions and comparability of study results. Moreover, successfully applying passive solar dryers as an alternative to the traditional use of solar energy requires overcoming challenges such as time consumption, limited quantities of dried products, and the periodic nature of solar radiation. Thus, given its ability to significantly improve the self-life of food and overcome the current limitations for effective utilization of solar dryers in SSA, the use of mixed mode passive greenhouse dryers is proposed.
