Damage Assessment of 3-D Printed Ceramic Sandwich Structures with an Auxetic Honeycomb Core Subjected to Quasistatic Indentation Loading
Authors: Liu Qiang , Guan Guoyang , Liao Baopeng , Zhao Zhe , Chen Laiming , Yu Jian
Published: August 2024

Ceramic sandwich structures (CSS) have become an important material in the aerospace industry because of their high strength and excellent thermal insulation properties. However, the brittle nature of ceramic makes them vulnerable to damage from foreign objects, which can reduce their load-bearing capacity. In this paper, a series of tests were designed to investigate the response of CSS to impacts from foreign objects. To realize the damage characteristics and failure modes under the indentation force, a quasistatic indentation (QSI) test was conducted on CSS. Additionally, an acoustic emission device was used to capture damage signals during the QSI testing. Thereafter the extent of damage was evaluated by analyzing the damaged area and the compression after indentation properties. The results of these tests revealed the failure mechanism maps and indicated that the compressive strength of the damaged CSS had a stronger correlation with damage to the honeycomb core than to the face sheet.
Interpreting and Managing Laboratory Data below the Quantification and Detection Threshold
Authors: Carson Polona K.
Published: August 2024

One of the problems of interpreting laboratory reports with data below reporting and detection limits is that there is no standard for reporting. Therefore, laboratories are using different nomenclature, definitions, and reporting formats for low-level data. Some knowledge of laboratory processes is often needed to find all the information required to accurately interpret laboratory reports. To make correct conclusions based on the statistical analysis of such data, a collaboration between a data analyst and a chemist to review the narrative explaining the data package and accurately interpret detection and reporting limits and data qualifiers is needed. This paper is written to aid data analysts and laboratory operational and quality managers in recognizing issues with reporting low-level data and to avoid common pitfalls in their interpretation.
Fracturing essayist conventions in comp I
Authors: Mitchell Candace
Published: August 2024

This article first analyzes the differing responses of three individuals who have read the same first draft of a paper assigned in an ESL college composition class. The analysis highlights the multiple ways in which a text can be read and how these “readings” are ideologically driven. The first reader reads the text from the perspective of a prescriptivist, the second reads for meaning though is sidetracked by mistaken assumptions regarding text structure, and the third reads the text for what it is: a poem. The author then provides a detailed thematic and linguistic analysis of the same student text and, in so doing, fractures preconceived notions of how meaning is conveyed, cohesion maintained, and sense made of experience, in this instance, when a student has been asked to write a memoir. The highly detailed analysis illuminates the complexity inherent in a text that in some contexts might draw little, if any, attention other than a request for a rewrite. In theend, the article raises concerns about the constraints academic essayist literacy imposes on some of our most basic and potentially, creative writers.
Open Research Reforms and the Capitalist University: Areas of Opposition and Alignment
Authors: Hostler Thomas J.
Published: August 2024

There is a need for more nuanced and theoretically grounded analysis of the socio-political consequences of methodological reforms proposed by the open research movement. This paper contributes by utilising the theory of academic capitalism and considering how open research reforms may interact with the priorities and practices of the capitalist university. Three manifestations of academic capitalism are considered: the development of a highly competitive job market for researchers based on metricized performance, the increase in administration resulting from university systems of compliance, and the reorganization of academic labour along principles of “post-academic science”. The ways in which open research reforms both oppose and align with these manifestations is then considered, to explore the relationships between specific reforms and academic capitalist praxis. Overall, it is concluded that open research advocates must engage more closely with the potential of reforms to negatively affect academic labour conditions, which may bring them into conflict with either university management, or those who uphold the traditional principles of an ‘all round’ academic role.
Religion in a Time of Crisis: Pagan Experiences of Liminality and Communitas During the COVID-19 Pandemic in Calgary, Alberta
Authors: Tolmie Maddi
Published: August 2024

The COVID-19 pandemic disrupted social norms and positioned people within a prolonged space of liminality wherein individuals experienced danger, vulnerability, and freedom due to an existence without associated social rules or taboos. A liminal existence, in Victor Turner’s definition, means to be between social structure or to exist in a space of anti-structure—the middle stage of his explanation of the process of a religious/social rite of passage (1974). I argue that the COVID-19 pandemic represented an instance of Turner’s (1974; 1997) anti-structure and that the resulting sensation of crisis communitas was a form of healing for some religious practitioners and communities. To investigate this hypothesis, I worked with a group of Pagan women in Calgary, Alberta, to inquire about their perceived shifts in the self and their community during the pandemic. This research explores the social experience of the COVID-19 pandemic for religious communities—namely the associated danger within liminality; the stage where practitioners began to feel unsteady in their lack of structure and identity, and the lifting of the veil; where the sensation of communitas brought together the Pagan community to use magic and ritual as a form of healing during mass crisis.

Published: August 2024

The phenomenon of students experiencing stress in learning mathematics is commonplace in this era of globalization. It is not uncommon for students to feel afraid when facing material or assignments presented by teachers at school. Therefore, this research aims to identify stress-coping strategies used by high school students in dealing with mathematics learning based on gender. This research uses descriptive quantitative methods. Data was obtained through a questionnaire containing 46 statement items, then distributed via Google Forms and statement sheets to students. The research respondents consisted of 89 students from tenth graders in one of the high schools in Tambun Selatan, Bekasi, West Java. Data analysis was carried out using the stress-coping percentage method. The research results show that both male and female students tend to use emotion-centered coping strategies, with a percentage of male respondents was 57% and female respondents had a percentage of 79%. Also, the coping strategy section that focuses on emotions tends more towards the sub-indicator of accepting responsibility with a percentage of 76% for male students and 78% for female students. It can be said that there is no difference between male and female students in solving a problem.

The research method used was explanatory sequential mixed methods. The research design used was Pretest-Posttest Control Group Design. The research population was grade VII students one of Junior High School in Kudus except students in the favourite class. The sample was taken by simple random sampling technique, so that grade VII F was obtained as experiment class and grade VII E as control class. Qualitative research subject were taken 6 subjects based on the mathematical early ability category. The result of the research showed that (1) the achievement of mathematical problem solving ability of the students who got Model Eliciting Activities had not reach the completeness classically; (2) the achievement and improvement of mathematical problem solving ability of the students who got Model Eliciting Activities were better than the students who got Problem Based Learning; (3) the students who got Model Eliciting Activities tend to be active and brave rather than the students who got Problem Based Learning; and (4) some of the studentsâ€™ difficulties, students with the high early mathematical ability in the experiment class did not face any difficulties, only the students were not careful in calculating, while in the control class faced the difficulty in making plans at number 4, thus influencing the next indicator. For students with the medium early mathematical ability in the experiment class faced the difficulty in determining the correctness of the answer and were not careful in calculating, while in the control class faced the difficulty in determining the correctness of the answer and making the plan at number 4 thus influencing the next indicator. Lastly, for students with low early mathematical ability in both experiment class and control class, they faced the difficulty in determining the truth of the answer and had not finished working on the four questions because the time provided has been exhausted.

Problem solving ability with mathematical modeling strategy in term of mathematics self-efficacy on Generative Learning Model
Authors: Sutrisno Hendrik , Kharisudin Iqbal
Published: August 2024

Problem Solving Ability (PSA) is the ability of students to determine how to solve a mathematical problems that have not yet been known how to solve it. Abstract mathematical concepts become obstacles in solving mathematical problems. Mathematical Modeling Strategy (MMS) is one ways that can be used to improve students' problem solving ability. In addition, one learning model that can improve students' problem solving ability is Generative Learning Model (GLM). The purpose of this study is to (1) find out whether the results of the PSA test achieve mastery learning, (2) find out whether the results of the PSA test have improved, (3) find out the relationship between the level of Mathematics Self-Efficacy (MSE) on students' PSA, and (4) describe the PSA in terms of students' MSE. The research method that used is mixed methods with quantitative methods using Pre-Experimental Design that modela is One-Group Pretest-Posttest Design. The research sample was taken with a multistage cluster sampling technique and research subjects were selected with a purposive sampling technique. The results showed that; (1) students' PSA achieve a mastery learning, (2) students' PSA have increased, (3) there is a positive influence between the level of MSE on students' PSA, (4) students with high levels of MSE tend to have better PSA than students with moderate and low levels of MSE.
The Effect of Positional Differences on Technical Parameters in Different Parts of the Pitch in Soccer
Authors: Böge Veysel
Published: August 2024

ABSTRACT
The aim of this study was to investigate the effect of positional differences on technical parameters in different parts of the pitch in soccer.
For this purpose, 22 healthy male soccer players participated in the study. The mean age of the participants was 22±1.46 years, mean height was 176.27±5.76 cm, mean body weight was 68.83±5.60 kg and mean body mass index (BMI) was 21.67± 1.23 kg/m2. The participants were divided into 3 groups according to their positions as defender, midfielder and attackers with 5 people in each group, in addition to this, a fixed group of 5 players was formed and two different goalkeepers were included in the study at different stages of the game. One-Way Anova test was used to determine the difference between the groups. In the first zone, the rating of perceived exertion (RPE) values of the attacker players showed a significant difference, while no difference was observed in the other parameters. In the second zone, only the ball possession (BP) values of midfielder players made a significant difference. In the third zone, both defense and midfielder players made more vertical and diagonal passes (DVP).
In conclusion, when the various technical actions of players in different positions in the three zones of the game are analyzed, although there are differences in some parameters, in general, positional differences in different zones do not show a significant change.
Keywords: Ball possession, diagonal passes, rating of perceived exertion and soccer.
