Why most psychological research findings are not even wrong

Psychology’s replication crisis is typically conceptualised as the insight that the published literature contains a worrying amount of unreplicable, false-positive findings. At the same time, meta-scientific attempts to assess the crisis in more detail have reported substantial difficulties to identify unambiguous definitions of the scientific claims in published articles and to determine how they are connected to the presented evidence. I argue that most claims in the literature are so critically underspecified that attempts to empirically evaluate them are doomed to failure — they are not even wrong. Meta-scientists should beware of the flawed assumption that the psychological literature is a collection of well-defined claims. To move beyond the crisis, psychologists must reconsider and rebuild the conceptual basis of their hypotheses before trying to test them.
Dissociated Deficits between Explicit and Implicit Empathetic Pain Perception in Neurofibromatosis Type 1

Cognitive impairments and social-function deficits are severe complaints in neurofibromatosis type 1 (NF1) patients. Empathetic pain perception may be disrupted in NF1 patients because of high-level cognitive deficits. This study investigated the empathy profiles of adult patients with NF1, especially concerning whether explicit and implicit empathetic pain perception are abnormal in this population. We examined empathetic pain perception through a paradigm based on perceiving another person’s pain; in this task, patients were required to make judgments about the presence of pain or the laterality of the body part, as shown in a picture. Twenty NF1 patients without obvious social or communication difficulties completed the task, and the results were compared with results from the normal controls (NCs). Regarding explicit empathetic pain processing, i.e., judging the presence of “pain” or “no pain”, there were no significant differences between patients and controls in accuracy or reaction time. However, in implicit empathetic processing, i.e., judging the laterality of “pain” or “no-pain” pictures, NF1 patients had significantly lower accuracy (p = 0.038) and significantly higher reaction times (p = 0.004) than the NCs. These results were consistent with those of a previous study showing that high-level cognitive deficits were prominent in NF1 patients when performing challenging tasks. The mechanisms and related brain network activity underlying these deficits should receive attention in the future.
Effects of power line voltage variations on different types of 400-W high-pressure sodium ballasts

This paper presents the results of laboratory tests to determine the effects of voltage sags, interruptions and fluctuations on high-pressure sodium (HPS) lamps and ballasts. The way these ballasted lamps react to sags and interruptions in the laboratory is then compared to a model of the real-world electrical environment created from data gathered during three recent North American power quality surveys. This work also shows how HPS immunity to voltage variations depends significantly on the ballast type and the lamp age.
Linear and Nonlinear Aeroelastic Analysis of Fighter-Type Wing with Control Surface

Linear and nonlinear aeroelastic analyses of a fighter-type wing with a control surface have been performed by using frequency-domain and time-domain analyses. Modes from free vibration analysis and a doublet-hybrid method are used for the computation of subsonic unsteady aerodynamic forces. The fictitious mass modal approach is used to reduce the problem size and the computation time in the linear and nonlinear flutter analyses. For the nonlinear flutter analysis, the control surface hinge is represented by a free-play spring and is linearized by using the describing function method. The linear and nonlinear flutter analyses indicate that the flapping mode of the control surface and the hinge stiffness have significant effects on the flutter characteristics. From the nonlinear flutter analysis, limit-cycle oscillation and chaotic motion are observed in a wide range of air speed below the linear flutter boundary, and a jump of limit-cycle oscillation amplitude is observed.
Comparative Risk of Bleeding of Anticoagulant Therapy with Vitamin K Antagonists (VKAs) and with Non-Vitamin K Antagonists in Patients Undergoing Dental Surgery

Objectives: A wide variety of approaches have been proposed to manage anticoagulant drugs in patients undergoing dental surgery; vitamin K antagonists and novel direct oral anticoagulants have been used. The present study aims to explore the existing evidence concerning the management of patients in anticoagulant therapy undergoing oral surgery procedures and to give suggestions related to peri- and post-operative measures. Materials and methods: A comprehensive search of databases was conducted to identify studies that evaluated the relationship between direct oral anticoagulants and dental procedures. The present scoping review was realized in adherence with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines. The publications varied from randomized controlled trials (RCT) to cohort trials. Only articles written in English language and published between 2000 to 2020 were screened. The studies were included if discussing the management of a patient in anticoagulant therapy (warfarin or direct oral anticoagulants) scheduled for tooth extraction. Results: 33 studies were selected and included in the qualitative review. Nineteen considered anticoagulant therapy with warfarin, six considered anticoagulant therapy with new oral anticoagulants and eight compared patients taking warfarin with patients taking direct oral anticoagulants. Conclusions: No case of extractive surgery should alter the posology of the drug: thromboembolic risks derived from discontinuation are heavier than hemorrhagic risks. Clinical relevance: direct oral anticoagulants are safer in terms of bleeding and manageability and bleeding episodes are manageable with local hemostatic measures.
Plume neutralization of an ionic liquid electrospray thruster: better insights from particle-in-cell modelling

Ionic liquid electrospray thrusters with high specific impulse, high thrust accuracy and low thrust noise are very promising for space gravitational wave detection missions. The plume, which may lead to surface charging of solar panels and sensitive spacecraft components is a great concern for the applications of electrospray thruster. Therefore, this paper investigates the plume neutralization process of the ionic liquid electrospray thruster through fully kinetic particle-in-cell simulations. The unipolarity operation mode is firstly simulated and compared with the experimental measurements. The bipolar operation mode is analyzed by considering the premixing and the separation of positive and negative ion beams. At the same time, the effect of beam spacing on the plume characteristics is investigated. The results show that the plume neutralization of the ionic liquid electrospray thruster is achieved by the spatial and temporal oscillations of the ion beams. In the horizontal direction, the spatial oscillations are caused by the different mass and hence velocities of positive and negative ions. In the vertical direction, the spatial oscillations are mainly because of the non-zero beam spacing. The temporal oscillations may be related to the tradition plasma oscillation. As the beam spacing increases, the oscillation amplitude of the horizontal electric potential curve changes scarcely; however, in the vertical direction, the oscillation amplitude of the curve increases. The ion temperature goes up with the beam spacing and the deviation of the temperature of beam ions does not exceed 15 eV in the horizontal direction but exceeds 100 eV in the vertical direction. Moreover, the plume divergence half angle and the beam spacing are positively correlated, suggesting that the ionic electrospray thrusters with positive and negative polarity need to be placed as close as possible in the spacecraft.
A New Mitochondrial Genome of Sogatella furcifera (Horváth) (Hemiptera: Delphacidae) and Mitogenome-Wide Investigation on Polymorphisms

Simple Summary We completed one mitogenome of white-backed planthopper (WBPH), Sogatella furcifera (Horváth), with finding heteroplasmy phenomenon confirmed by PCR reaction and Sanger sequencing method. This heteroplasmy was not observed in WBPHs (n = 24) collected from the fields, suggesting that it may be uncommon in fields. We also analyzed single nucleotide polymorphisms, insertion and deletions, and simple sequence repeats among three currently available WBPH mitogenomes of Korea and China, suggesting that identified intraspecific variations could be potential candidates for developing markers to distinguish geographical populations of WBPH including Korean and Chinese. Phylogenetic analysis of 32 mitogenomes of Delphacidae including the three WBPH mitogenomes suggested that Delphacinae seems to be monophyletic and Sogatella species including WBPH are clearly formed as one clade. Abstract White-backed planthopper (WBPH), Sogatella furcifera (Horváth), is one of the major sap-sucking rice pests in East Asia. We have determined a new complete mitochondrial genome of WBPH collected in the Korean peninsula using NGS technology. Its length and GC percentages are 16,613 bp and 23.8%, respectively. We observed one polymorphic site, a non-synonymous change, in the COX3 gene with confirmation heteroplasmy phenomenon within individuals of WBPH by PCR amplification and Sanger sequencing, the first report in this species. In addition, this heteroplasmy was not observed in wild WBPH populations, suggesting that it may be uncommon in fields. We analyzed single nucleotide polymorphisms, insertion, and deletions, and simple sequence repeats among the three WBPH mitogenomes from Korea and China and found diverse intraspecific variations, which could be potential candidates for developing markers to distinguish geographical populations. Phylogenetic analysis of 32 mitogenomes of Delphacidae including the three WBPH mitogenomes suggested that Delphacinae seems to be monophyletic and Sogatella species including WBPH are clearly formed as one clade. In the future, it is expected that complete mitogenomes of individuals of geographically dispersed WBPH populations will be used for further population genetic studies to understand the migration pathway of WBPH.
Behavior of Reinforced and Posttensioned Concrete Members with a UHPFRC Overlay under Impact Loading

The impact response of reinforced and posttensioned concrete members with ultrahigh-performance fiber-reinforced concrete (UHPFRC) overlay was studied. This paper presents the results of nine drop weight slab strip tests. Major parameters for the tests were the reinforcement configuration of the concrete substrate, the addition of reinforcing bars in the UHPFRC layer, and the static system. Two reinforced and posttensioned concrete slabs were tested for reference. Five slab strips were tested under static loading conditions for comparison. A three-point bending and a cantilever system were used in the drop weight tests to induce flexural compression or tension in the upper UHPFRC layer. The addition of a UHPFRC overlay improved the structural response: no crushing or spalling occurred in the UHPFRC at the impact location. The UHPFRC had a load distributing function, which led to reduced crack widths in the substrate and lower member deflections.
Validating CFD predictions of nasal spray deposition: Inclusion of cloud motion effects for two spray pump designs

Abstract Momentum transfer from nasal spray droplets to the surrounding gas may create droplet cloud motion and influence nasal deposition patterns. The objective of this study was to develop a validated computational fluid dynamics (CFD) model of nasal spray deposition for two different spray-pump designs that includes cloud motion effects (i.e. two-way coupling) in a computationally efficient manner. Spray droplet transport and deposition were simulated in an average adult nasal airway model (that captures average drug delivery) using both two-way coupled and one-way coupled Euler-Lagrange frameworks. CFD model accuracy was established by comparing predictions of the two-way and one-way modeling frameworks with in vitro measurements. The two-way coupled simulation showed that momentum from the spray cloud resulted in displacement of surrounding gas, leading to an upward air velocity in the direction of the spray, which significantly increased the travel distance of smaller droplets with diameters equal to a median diameter of ∼70 µm and below. For the Flonase Sensimist spray pump, two-way coupling produced <10% relative error in posterior deposition fraction compared with the in vitro data, versus 47% relative error using one-way coupling. For the Flonase spray pump, two-way coupling did not improve posterior deposition agreement with both methods having a relative error of ∼30%; however, two-way coupling showed substantial increase in posterior deposition. As a result, two-way coupling is likely needed for the simulation of most nasal spray pumps and additional factors may be important to better capture final formulation distribution of the Flonase product, like post-deposition liquid motion.

Improving Science Learning Outcomes Through the SETS (Science Environment Technology And Society) Approach

Science learning packaging still focuses on conventional learning. This causes students to feel bored in learning and have difficulty understanding the material taught by the teacher. This problem affects the students' low science learning outcomes. This study aims to analyze the significant differences in science learning outcomes for groups of students who are taught through the application of the SETS approach and students who are taught through conventional learning. This type of research is a quasi-experimental research design with nonequivalent control group design. The population and sample in this study were all students in grades IIIa and IIIb, totaling 61 people. The data collection technique in this research is a test. The technique used to analyze the data is using t-test statistical analysis. The results showed that there was a significant difference in science learning outcomes between the experimental and control groups as seen from the value of tcount = 5.862 > ttable = 2,000. Based on the results of the study, it can be concluded that the SETS approach has an effect on students' science learning outcomes. This research implies that the SETS approach can assist teachers in developing the learning process.
Wire Laser Metal Deposition Additive Manufacturing of Duplex Stainless Steel Components—Development of a Systematic Methodology

A systematic four-stage methodology was developed and applied to the Laser Metal Deposition with Wire (LMDw) of a duplex stainless steel (DSS) cylinder > 20 kg. In the four stages, single-bead passes, a single-bead wall, a block, and finally a cylinder were produced. This stepwise approach allowed the development of LMDw process parameters and control systems while the volume of deposited material and the geometrical complexity of components increased. The as-deposited microstructure was inhomogeneous and repetitive, consisting of highly ferritic regions with nitrides and regions with high fractions of austenite. However, there were no cracks or lack of fusion defects; there were only some small pores, and strength and toughness were comparable to those of the corresponding steel grade. A heat treatment for 1 h at 1100 °C was performed to homogenize the microstructure, remove nitrides, and balance the ferrite and austenite fractions compensating for nitrogen loss occurring during LMDw. The heat treatment increased toughness and ductility and decreased strength, but these still matched steel properties. It was concluded that implementing a systematic methodology with a stepwise increase in the deposited volume and geometrical complexity is a cost-effective way of developing additive manufacturing procedures for the production of significantly sized metallic components.
Interactive Data Visualization Enhances Preventive Intentions in COVID-19 News Stories: The Mediating Role of Fear and the Moderating Role of Political Orientation

ABSTRACT The current study investigates the impact of interactive visualization of scientific data in COVID-19 news on audiences’ fear arousal, perceived threat, and preventive intentions. An experiment compared the interactive and non-interactive versions of a news story that visualized big data of the rapid spread of coronavirus (N = 153). Results showed that interactive visualization evoked more intense fear arousal, which led to higher levels of perceived threat of COVID-19 and preventive intentions against the virus. Participants with higher conservatism were more susceptible to this effect, even after controlling for their maladaptive perceptions that downplay the threat of the pandemic.
A Safety Probability Assessment at the Transportation-Planning Level: Should an Ordered or Unordered Response Be Used?

In the context of urban network safety management, this article presents an alternative approach based on a qualitative response model, namely, the multinomial logit model. The main objective of this article is to compare and analyze the use of ordered and unordered mechanisms (such as the multinomial logit model) and consequently to select the appropriate model. To achieve this objective, urban segment data from Porto, Portugal, for a 5-year period were used. The ordered and the multinomial models were applied to estimate the parameters and marginal effects, considering three responses to reflect degrees of hazard (low, medium, and high). To compare and select the best model, statistical tests were conducted, and performance measures were obtained. Although similar results were obtained, the adjusted likelihood ratio test showed that the multinomial model was preferred. Moreover, to illustrate and compare a safety assessment using both models, the probability of each hazard level occurring was computed for two urban segments and hypothetical planned scenarios were defined. It was interesting to note that despite the slight apparent differences between the two models, great differences were found in the category probability model results, proving the importance of model structure selection.
Crashworthiness study of a full vehicle-lumped model using parameters optimisation

In this study, a new full vehicle-lumped model is presented for frontal crash investigation considering energy absorption. The proposed model which has 12 degrees of freedom (DOF) involves all important structural parts. What makes this study important is a new algorithm related to system identification including problem-solving and genetic algorithm (GA) to find the unknown lumped parameters. In addition, GA was used for calculating the optimised parameters of 12-DOF model for two vehicle types (a sedan and a pick-up) in two different frontal crashes. The vehicle responses of proposed lumped model have been compared to the experimental responses for vehicles, a sedan and a pickup diachronically. The results show that the proposed full vehicle-lumped model with calculated parameters can accurately simulate the deceleration and velocity reduction for vehicle and occupant. Furthermore, by adding a mass as a barrier, the model is improved to simulate the cases of excitation. In addition, in this study the shape of the excitation force on the lumped parameter models (LPMs) is investigated; and a hybrid force of sinusoidal and cosine excitations to replace instead of crash pulse is presented. Overall, the purpose of this work is to create a model which can be used alone or to determine the lumped parameters of combined lumped mass and finite-element (FE) models.
Effects of High-Intensity Interval Training on Inflammatory Biomarkers in Patients with Type 2 Diabetes. A Systematic Review

Background: Due to the prevalence and incidence worldwide of type 2 diabetes, and the significant role physical activity plays in these patients, a systematic review has been conducted to find out the effects that high-intensity interval training has on inflammatory biomarkers in subjects with type 2 diabetes. This project aims to determine the effect this training modality has on inflammatory biomarkers, in addition to observing its effects on the values of body composition and determining if this is a more effective, less effective or equally effective alternative to standard aerobic or resistance training. Methods: A search was conducted in the months of November and December 2020 on different databases: Pubmed, WoS and PEDro. A protocol for this systematic review was registered in PROSPERO (Registration number: CRD42021281186). The studies selected met the previously defined inclusion criteria, and the methodological quality of the papers used was evaluated according to the Downs and Black Checklist. Results: Out of 46 studies found, seven were included. The most relevant data concerning the characteristics of the clinical trials and HIIT characteristics, the values of body composition and the biomarkers under study were extracted from each study. Moreover, the results obtained from the different studies were described. Conclusions: HIIT could have an effect on inflammatory biomarkers. There is likely to be a relationship between changes in inflammatory profile and fat loss. A controlled diet may be a good complement to reduce the inflammatory profile. Further studies are required to determine whether HIIT is a better, worse or an equivalent alternative to medium-intensity aerobic exercise to improve the inflammatory profile.
Occurrence of methicillin-resistant staphylococci in the pig-production chain in Ibadan, Nigeria

Staphylococcus species colonises humans and animals and is a major food contaminant with public health significance. Here, we assessed the occurrence of methicillin-resistant staphylococci (MRS) in the pig-production chain in Ibadan, Nigeria. Nares of 120 pigs and 10 farmers were sampled with sterile swabs whilst 54 pork samples were collected from a retail slaughterhouse. Staphylococcus species were isolated using enrichment, cefoxitin–aztreonam selective broth and Mannitol salt agar. Isolates were tested for susceptibility to cefoxitin (30 μg), oxacillin (1 μg) and vancomycin (30 μg). Methicillin-resistant staphylococci isolates were characterised using conventional biochemical tests. From 184 samples, 364 staphylococcal isolates were obtained. Amongst the 54 pork samples, 44.0% were contaminated with Staphylococcus species. Overall, 9 (2.5%) MRS were obtained and presumptively identified as Staphylococcus xylosus (n = 3), Staphylococcus sciuri (n = 3), Staphylococcus warneri (n = 2) and Staphylococcus cohnii (n = 1). There was no relationship between the prevalence of MRS between pigs and pig handlers in the farms, but Farm 2 had the highest frequency of 66.7% (p < 0.05). Piglets had the highest prevalence of 66.7% (p < 0.05) whilst MRS was absent in workers and pork samples. This study raises concerns about the cross-contamination of staphylococci in the food chain. Constant surveillance is imperative to ensure food safety.
