Published: August 2021

Cavity optomechanical systems enable interactions between light and mechanical resonators, providing a platform both for fundamental physics of macroscopic quantum systems and for practical applications of precision sensing. The resonant enhancement of both mechanical and optical response in the cavity optomechanical systems has enabled precision sensing of multiple physical quantities, including displacements, masses, forces, accelerations, magnetic fields, and ultrasounds. In this article, we review the progress of precision sensing applications using cavity optomechanical systems. The review is organized in the following way: first we will introduce the physical principles of optomechanical sensing, including a discussion of the noises and sensitivity of the systems, and then review the progress in displacement sensing, mass sensing, force sensing, atomic force microscope (AFM) and magnetic resonance force microscope (MRFM), accelerometry, magnetometry, and ultrasound sensing, and introduce the progress of using quantum techniques especially squeezed light to enhance the performance of the optomechanical sensors. Finally, we give a summary and outlook.
Preference Change and Behavioral Ethics: Can States Create Ethical People?
Authors: Feldman Yuval , Kaplan Yotam
Published: August 2021

Law and economics scholarship suggests that, in appropriate cases, the law can improve people’s behavior by changing their preferences. For example, the law can curb discriminatory hiring practices by providing employers with information that might change their discriminatory preference. Supposedly, if employers no longer prefer one class of employees to another, they will simply stop discriminating, with no need for further legal intervention. The current Article aims to add some depth to this familiar analysis by introducing the insights of behavioral ethics into the law and economics literature on preference change. Behavioral ethics research shows that wrongdoing often originates from semi-deliberative or non-deliberative cognitive processes. These findings suggest that the process of preference change through the use of the law is markedly more complicated and nuanced than previously appreciated. For instance, even if an employer’s explicit discriminatory stance is changed, and the employer no longer consciously prefers one class of employees over another, discriminatory behavior might persist if it originates from semi-conscious, habitual, or non-deliberative decision-making mechanisms. Therefore, actual change in behavior might necessitate a close engagement with people’s level of moral awareness. We discuss the institutional and normative implications of these insights and evaluate their significance for the attempt to improve preferences through the different functions of the legal system.

Authors: Sezer Hale , Şahin Hatice
Published: August 2021

Objectives

Skills training is carried out with coaching in nursing education and all stakeholders are important. The aim of study was to evaluate the views of different stakeholders on coaching practice and the costs.

Methods

Data was collected between October 2015 and December 2016. The student dimension was evaluated using the Coaching Process Evaluation Scale with sophomore (n=237) and junior (n=219). Data was collected from the faculty member (n=18) using Critical Incidents Technique and from the educational managers (n=7) through in-depth interviews. The 2015–2016 educational program was analyzed for cost analysis.

Results

Student evaluations of the Coaching Process Evaluation Scale demonstrated mean scores of 66.68 ± 0.85 for the Observed Coaching Skills subscale. There were four headlines (use of coaching skills, benefiting from the Coaching Process, Emotions, and Reflection) which were also observed in the faculty members data which revealed a total of 60 codes from positive and negative incidents. The educational managers, on the other hand, stressed three categories and the emotions category, which emerged in the students and faculty was not found among the educational managers. The per student cost of practice education increase sixfold from the freshman year to the junior year.

Conclusions

The perception and views on coaching practices of educational managers, faculty members, and students are positive and support each other. This provides an important opportunity for the placement of coaching practices into education programs in nursing.
Transcranial Direct Current Stimulation above the Medial Prefrontal Cortex Facilitates Decision-Making following Periods of Low Outcome Controllability
Authors: Csifcsák Gábor , Bjørkøy Jorunn , Kuyateh Sarjo , Reithe Haakon , Mittner Matthias
Published: August 2021

Recent studies suggest that choice behavior in reinforcement learning tasks is shaped by the level of outcome controllability. In particular, Pavlovian bias (PB) seems to be enhanced under low levels of control, manifesting in approach tendencies toward rewards and response inhibition when facing potential losses. The medial prefrontal cortex (mPFC) has been implicated both in evaluating outcome controllability and in the recruitment of cognitive control (CC) to suppress maladaptive PB during reinforcement learning. The current study tested whether high-definition transcranial direct current stimulation (HD-tDCS) above the mPFC of healthy humans can influence PB, and counteract the previously documented, deleterious behavioral effects of low outcome controllability on decision-making. In a preregistered, between-group, double-blind study (N = 103 adults, both sexes), we tested the interaction between controllability and HD-tDCS on parameters of choice behavior in a Go/NoGo task. Relative to sham stimulation, HD-tDCS resulted in more robust performance improvement following reduced control, an effect that was more pronounced in appetitive trials. In addition, we found evidence for weaker PB when HD-tDCS was administered during low controllability over outcomes. Computational modeling revealed that parameter estimates of learning rate and choice randomness were modulated by controllability, HD-tDCS and their interaction. Overall, these results highlight the potential of our HD-tDCS protocol for interfering with choice arbitration under low levels of control, resulting in more adaptive behavior.

Published: August 2021

The implicit association test (IAT) is widely used to measure evaluative associations towards groups or the self but is influenced by other traits. Siegel, Dougherty, and Huber (2012, Journal of Experimental Social Psychology) found that manipulating cognitive control via false feedback (Study 3) changed the degree to which the IAT was related to cognitive control versus evaluative associations. We conducted two replications of this study and a mini meta-analysis. Null-hypothesis tests, meta-analysis, and a small telescope approach demonstrated weak to no support for the original hypotheses. We conclude that the original findings are unreliable and that both the original study and our replications do not provide evidence that manipulating cognitive control affects IAT scores.

Published: August 2021

Weight reduction of components is the main aim of different industrial sectors. This leads to increasing application areas of fiber composites for primary structural components. Aiming this objective, a new lightweight Fiber/Metal Laminate (FML) has been developed. Fiber metal laminate is one such material which is being widely investigated for its performance compared to existing material.. The most commercially available fiber metal laminates (FML’s) are ARALL (Aramid Reinforced Aluminium Laminate), based on aramid fibers, GLARE (Glass Reinforced Aluminium Laminate), based on high strength glass fibers and CARALL (Carbon Reinforced Aluminium Laminate), based on carbon fibers. The mechanical properties of FML show advantages over the properties of both aluminium alloys and composite materials individual. This paper reviews relevant literature which deals with different manufacturing techniques for FML’s with excellent properties under tensile, flexure and impact conditions. It also reviewed recent modeling techniques on FML’s. Modeling of tensile, flexure and impacts behavior on fiber metal laminates requires understanding the bonding between the metal and composite layer. Further research is necessary in the assessment of mechanical performance of complex structures in real world conditions.

Combined effects of geometric and material non-linearities on a uniform column subjected to an axial compressive load are presented in the present note. A simple, direct iterative numerical method has been proposed to study the geometric and material non-linear behavior of columns subjected to varying boundary conditions. Introduction of material non-linearity in the large deﬂection analysis of columns subjected to an axial compressive load reveals a reduction in Euler stress obtained when compared to the effect of geometric non-linear analysis and increase in the same when compared to the eﬂect of material non-linear analysis. A convergence study has been carried outfor the results obtained from the proposed iterative method to prove the efficacy.

Published: August 2021

Estuaries play an invaluable role in the transformation and cycling of materials as they move between land and sea; including anthropogenic materials. Increasingly, human land use is delivering material loads that risk overwhelming the normal functions that these ecosystems provide. In this context, the objective of this study is to assess key biogeochemical processes to understand the connections of anthropogenic activities on ecosystem performance in a tropical estuarine lagoon system. This research focuses on a case study area, Dong Ho lagoon in Vietnam, which exemplifies the anthropogenic impacts and management issues facing most of the Mekong coastline and other similar areas in Vietnam. Located at the south-western edge of the Mekong delta, the Dong Ho estuary is subject to material inputs from both local and more remote sources; making it vulnerable to degradation and functional loss. This paper summarises the key findings from an assessment of the Dong Ho estuarine functions and highlights potential risks it is currently facing.

Authors: Ikpe A.E. , Owunna I.B.
Published: August 2021

Variations of welding parameters and their effects on weld bead width of gas Tungsten Arc Weldment of 10 mm (thickness) AISI 1020 low carbon steel plate was investigated in this paper. Welding experimentation was carried out for Twenty seven (27) runs with three (3) ranges of current (120A, 150A and 190A), three (3) ranges of voltage (19V, 21V and 25V) and three (3) ranges of gas flow rate (13, 15 and 18 L/min) respectively. Applying the same range of parameters as inputs in Solid Works 2017 version, Finite Element Method (FEM) was employed to predict the weld bead width variations. To avoid wider weld bead width which can contribute to poor weld quality, a condition was established, in which the bead width values from both experimental and FEM prediction must not exceed 1.25 mm. Thermal transient flow simulation was also carried out with Solid Works 2017 version to determine the melting behavior of the material which revealed 1694 K as the solidus temperature and 1738 K as the liquidus temperature. It was observed that varying the welding current, arc voltage and the gas flow rate for the welding experimentation and finite element simulation, alternating weld bead widths of close proximity were produced. However, certain sets of parameters used for the welding experimentation met the aforementioned condition (≤1.25 mm) with the following values 1.02 mm, 1.05 mm, 1.10 mm, 1.07 mm, 1.15 mm and 1.19 mm while the same combination of parameters in the FEM met the condition with the following FEM predicted values 1.0 mm, 1.03 mm, 1.08 mm, 1.05 mm, 1.13 mm and 1.15 mm respectively. These findings are only applicable to AISI 1020 low carbon steel, therefore, melting point of materials should be adequately understood with proper knowledge of welding parameters prior to commencement of welding operation to avoid excessive increase in weld bead width.
Characteristic of Safety Recovery Zone and Roadside Hazard Cases in Malaysia Road: A Review
Authors: Kunji A.K.
Published: August 2021

The increasing number of highway crashes and the rising rate of fatality on run-off-road accidents has alarmed institutions to introduce design guidelines, evaluate their outcomes and improve the guidelines accordingly. This paper presents a case study on some of the existing roadside hazards in Malaysia, their impact to motorists, and reviews the current related provisions in the published design guidelines. Observations and in-depth study were made to the selected existing roadside hazards and assess their compliance to the available design guidelines and recommend improvement to some areas. The scope of the study covers on roadside trees, lighting and signboard poles, drainage structures, kerbs and safety barriers. The previously planted trees of less than 100 millimetres diameter within the clear zone of 9 and 6 meters to rural and urban roads respectively have grown in size to more than 500 mm diameters over 15 years, and today they have become hazards and causing deaths or serious injuries to passengers. The lighting and signboard poles installed near to the travel lane have resulted in high impact collisions to the extent of splitting vehicles and killing the motorists. The current roadside drainage structures are made of concrete and some with rubble lined walls are harmful and have been killing and injuring motorists when they are placed within the roadside safety recovery zone or corridor that are meant for skidding errant vehicle to make recovery traversing back to travel lane. The study showed some roadside barriers are not correctly applied and have become hazards instead of protecting the motorists. The outcomes of the case study suggest improvement to the design guidelines and roadside physical condition to minimise hazards to motorists.

Authors: Aniekan E. Ikpe , Ikechukwu Owunna
Published: August 2021

This study involves a comparative analysis of a designed automatic cooling power hacksaw machine and manual cooling power hacksaw machine in a local sawmill where coolant is applied manually by the operator. The automatic cooling power hacksaw machine took an average time of 40 s to cut an average mass of 5.9 kg with average Specific Mechanical Energy (SME) of 29 kj/kg and average cutting speed of 270 rpm. However, the manual cooling hacksaw machine took an average time of 53 s to cut the same average mass of 5.9 kg with average SME of 42 kj/kg and average cutting speed of 269 rpm. The basic idea behind SME was to determine the energy going into the cutting operation process per unit mass of timber in form of work from the motor. From the above stated results, the automatic cooling hacksaw machine designed in this study took less time, less SME and slightly higher cutting speed to cut the same quantity of timber than the manual cooling hacksaw machine. Compared to the manual cooling power hacksaw, the automatic cooling power hacksaw machine is obviously more efficient in terms of time and energy savings.

Published: August 2021

Automation offers a promising solution to improve competitiveness for the labor-intensive furniture manufacturing sector in Malaysia. This study evaluated the level of application of automation, the factors driving it, and the readiness of the furniture manufacturers towards Industry 4.0. A questionnaire-based survey was targeted to large and medium-sized furniture manufacturers throughout Malaysia, with responses from 312 manufacturers. The results revealed that the panel-based furniture manufacturers were more responsive towards the adoption of automated technologies than other types of furniture manufacturers. The machining centers and finishing operations within the furniture factories showed the highest application of automated technologies. The factor analysis revealed that the drivers for the application of automated technologies were the desire for higher production capacity, cost involved, product characteristics, and government policy. This study emphasized that in the cost-sensitive furniture manufacturing industry, the economic benefits of applying automation outweigh any other factor in the decision to explore such technologies. The study also revealed that furniture manufacturers are not ready to adopt Industry 4.0, and any efforts by the government to push for such transformation will require the provision of incentives and other tangible economic benefits.

OBJECTIVES

Pediatric emergencies can occur in pediatric primary care offices. However, few studies have measured emergency preparedness, or the processes of emergency care, provided in the pediatric office setting. In this study, we aimed to measure emergency preparedness and care in a national cohort of pediatric offices.

METHODS

This was a multicenter study conducted over 15 months. Emergency preparedness scores were calculated as a percentage adherence to 2 checklists on the basis of the American Academy of Pediatrics guidelines (essential equipment and supplies and policies and protocols checklists). To measure the quality of emergency care, we recruited office teams for simulation sessions consisting of 2 patients: a child with respiratory distress and a child with a seizure. An unweighted percentage of adherence to checklists for each case was calculated.

RESULTS

Forty-eight teams from 42 offices across 9 states participated. The mean emergency preparedness score was 74.7% (SD: 12.9). The mean essential equipment and supplies subscore was 82.2% (SD: 15.1), and the mean policies and protocols subscore was 57.1% (SD: 25.6). Multivariable analyses revealed that independent practices and smaller total staff size were associated with lower preparedness. The median asthma case performance score was 63.6% (interquartile range: 43.2–81.2), whereas the median seizure case score was 69.2% (interquartile range: 46.2–80.8). Offices that had a standardized process of contacting emergency medical services (EMS) had a higher rate of activating EMS during the simulations.

CONCLUSIONS

Pediatric office preparedness remains suboptimal in a multicenter cohort, especially in smaller, independent practices. Academic and community partnerships using simulation can help address gaps and implement important processes like contacting EMS.
Pediatric Preventive Care: Population Health and Individualized Care
Authors: Schor Edward L. , Bergman David
Published: August 2021

Well-child care is a near-universal service for young children toward which a great deal of time and professional resources are devoted but for which there is scant evidence of effectiveness in routine practice. It is composed of many components, the value of which likely varies with the quality of their provision and the needs and priorities of the children and families who receive them. Achieving more efficient and effective preventive care will require that pediatric practices segment the population they serve and design schedules and staffing to match patients’ health, well-being, personal and social circumstances, and service needs. Care should be individualized and include essential screening, tests, procedures, and education on the basis of assessment of patients’ and families’ needs and priorities. The traditional schedule of individual, comprehensive preventive care visits should be reconsidered and replaced with a schedule that allows complete care to be provided over a series of visits, including those for acute and chronic care. Preventive pediatric care should be provided in family-centered, team-based practices with strong linkages to other providers in the community who serve and support children and families. Care should make use of the wide variety of modalities that exist, and face-to-face time should be reserved for those services that are both important and uniquely responsive to in-office intervention. This model of preventive care will require changes in training, responsibilities and reimbursement of health care team members, and enhanced communication and collaboration among all involved, especially with families.
Model of Psychological Empowerment Based on Structural Equations for Predicting Autonomy
Authors: Muñoz-Márquez Clara Edith , Morales Barrera Raquel , Domínguez Espinosa Alejandra del Carmen
Published: August 2021

The study relies on the assumption that one of the main effects of phycological empowerment composed by attributes like self-esteem, locus of control, and assertiveness, is increased autonomy. The theoretical arguments are tested based on a structural equation model that allows estimating hypothetical relationships simultaneously. Additionally, differences in means between women and men are estimated for each phycological variable and the hypothetical model is tested separately to both sexes. 1,569 people (56% women) from five Mexican States compose the sample. The average age is 29 years and 59% of the sample has college degrees. The results suggest that psychological empowerment is strongly related to autonomy.

Verification of the Internal Structure of the Dimensional Clinical Personality Inventory 2 in a Brazilian Community Sample
Authors: Carvalho Lucas Francisco , Gonçalves André Pereira , Almeida Juliana Araújo , Macedo Fernanda Mello
Published: August 2021

The internal structure is investigated in mental health measures, exploring or confirming the association of stimuli composing the test and whether this structure is consistent with expectation. Our focus is on the internal structure of the Dimensional Clinical Personality Inventory 2 (idcp-2), a self-report test for pathological traits measurement. Previous studies have only partially verified the internal structure of idcp-2. The objective of this study is to verify the internal structure of idcp-2, contemplating in the same analysis all its dimensions and factors. Participants were 2,000 people from the general population. We conducted confirmatory (cfa) and exploratory (efa) factorial analyzes, including bifactor models. The results showed the bifactor model with 12 specific factors with best fit indices. The internal consistency for the general factor was above .90, and from .40 to .91 for the specific factors. Findings suggested the original solution of idcp-2 is reasonable using a bifactor model.

Motivation and Strategies for Reading Comprehension in Middle School
Authors: Ferraz Adriana Satico , Inácio Amanda Lays Monteiro , Pinheiro Mirelle Christina , Dos Santos Acácia Aparecida Angeli
Published: August 2021

In this study, we investigated the relationships among achievement goals, self-efficacy, reading strategies, and the self assessment of performance in 47 Middle School students with control of the variable’s history of repetition, school year, and age. The differences in the students’ self-assessment regarding the practice of recreational reading were also analyzed. The students responded to three scales of the Multidimensional Battery of Reading Comprehension Self-Regulation. Statistically significant correlations were identified among the motivational constructs, reading strategies, self-assessment, and achievement goals. We identified differences in the indices between the bivariate and partial correlations. The achievement goals were predictors  of self-efficacy and reading strategies. These three constructs predicted the students’ self assessment in Portuguese language and reading comprehension. Students who practiced recreational reading presented a higher self-assessment than students who did not have this habit. It is suggested to continue the investigations on the theme and incorporate the findings of this study into the pedagogical practices that encourage reading.

Between two worlds: Exploring esports betting in relation to problem gambling, gaming, and mental health problems
Authors: Marchica Loredana , Richard Jérémie , Mills Devin , Ivoska William , Derevensky Jeffrey
Published: August 2021

Background and aims

Esports betting is an emerging gambling activity where individuals place bets on an organized video gaming competition. It represents only one of several gambling activities commonly endorsed by adolescents. To date, limited research has explored the relationship between esports betting and mental health among adolescents and its convergence with both problem gambling (PG) and problem video gaming (PVG). The present study examined the relation between esports betting, PG and PVG, and both externalizing and internalizing problems among adolescents while accounting for adolescents' video gaming intensity (i.e., how often they play 2 h or more in a day) and engagement in other gambling activities.

Methods

Data was collected from 6,810 adolescents in Wood County, Ohio schools. A subset of 1,348 adolescents (M
age = 14.67 years, SD = 1.73, 64% male) who had gambled and played video games during the past year were included in the analyses.

Results

Approximately 20% (n = 263) of the included sample had bet on esports during the past year. Esports betting was positively correlated with other forms of gambling, both PG and PVG, and externalizing behaviors. Mediation analyses revealed esports betting was associated to both internalizing and externalizing problems through PVG and not PG.

Conclusions

Esports betting may be particularly appealing to adolescents who are enthusiastic video gamers. As such, regulators must be vigilant to ensure codes of best practices are applied to esports betting operators specifically for underaged individuals.
The Big Five personality traits and online gaming: A systematic review and meta-analysis

Online gaming has become an essential form of entertainment with the advent of technology and a large sway of research has been undertaken to understand its various permutations. Previous reviews have identified associations between the Big Five personality traits and online gaming, but a systematic review and meta-analysis on the association between these constructs has yet to be undertaken. In the current study we aimed to fill this gap in the literature through a systematic review and meta-analysis comprising of 17 studies and 25,634 individuals (AgeMean = 26.55, males = 75%). The findings showed that agreeableness, extraversion, openness to experience, and neuroticism were not ubiquitously associated with online gaming. The findings showed that only conscientiousness, across samples, had a protective role in online gaming. Furthermore, there were non-significant variations in the Big Five personality traits associations with online gaming when comparing gamers to the general population, younger versus older participants, casual versus ‘hardcore’ gamers, and high versus low traits (with the exception of neuroticism). As a result of our observations, the underlying mechanisms of individual differences in online gaming remain unclear. Limitations and future directions for research are discussed.
