The Impact of the Educational Counselor in Promoting Student Achievement Level in Government Schools at Irbid Governorate From School Principal Perspective

One of the purposes and objectives of this research is to identify and assess the impact of the effectiveness of a school counselor on the academic success of students-an effectiveness that is manifested through the provision of academic, psychosocial, and vocational support to students, as well as through the facilitation of the interactions among students, teachers, and parents. In order to accomplish this study, the opinions of 180 public school principals were sought, and they were selected randomly to allow unbiased and generalizable interpretations of the principals in the governorate of Irbid to be the research population. A survey method was employed for data collection, and it consisted of a survey specifically designed for this research study, which contained several paragraphs related to the primary areas of the school counselor's role, as listed above. The responses collected were analyzed by establishing the means and the standard deviations. This research aimed to understand better the significant contribution that school counselors can offer in enhancing the educational process and academic progress within public schools in Irbid. It also confirmed that the multi-faceted support that they provide is essential. Results. In the study evaluating the role of the educational counselor within the scope of the public schools of Irbid, the results of which have been collected from school principals, the work provides a positive evaluation of the perceived influence of the counselors in terms of students' academic achievement across four primary dimensions: academic support that had a mean of 4.2 and a standard deviation of 0.8; psychological support with a mean of 4.0 and standard deviation of 0.9; vocational guidance with a mean of 3.8 and a standard deviation of 0.7; and interaction with parents and teachers with a mean of 4.1 and a standard deviation of 0.6. Such results reveal a high appreciation of the importance of the role of the educational counselor in improving the educational environment and the comprehensive support for the student as the role of the counselor has been exposed as a practical element in supporting the student academically and psychologically, guiding the student professionally, and in addition promoting effective communication between the school and the family.

From awareness to action: Understanding the relationship between circular economy and favourable evaluation towards sustainable development

AbstractThis study examines the effects of heightened awareness of circular economy (CE) principles on individuals' evaluations of sustainable development within Brazil's resource‐rich yet environmentally challenged context. Employing social learning theory (SLT) as our theoretical framework, we investigate how increased knowledge of CE influences individuals' cognitive perceptions, enhancing their understanding and favourable assessment of sustainable practices. Data were collected through a nationwide survey of the general public, incorporating five CE dimensions: waste management, rational use of resources, technical cycle, sustainable products/packaging and dematerialization/collaborative consumption. Our results reveal that a deeper awareness of CE significantly improves individuals' positive evaluations concerning the environment, future generations' survival, socio‐economic development and engagement between people and institutions in sustainable practices. These positive evaluations are indicative of a shift in perception that precedes and may catalyse sustainable behaviours, suggesting that cognitive engagement is a critical precursor to actionable change. The study confirms that SLT effectively elucidates the bidirectional and complex interaction between cognition and evaluation within environmental contexts, thereby enriching the understanding of how sustainable practices can be adopted and promoted. The implications of our research are profound, suggesting that educational and policy interventions aimed at increasing CE knowledge could substantially impact sustainable development outcomes.

CapsRule: Explainable Deep Learning for Classifying Network Attacks.

Despite the potential deep learning (DL) algorithms have shown, their lack of transparency hinders their widespread application. Extracting if-then rules from deep neural networks is a powerful explanation method to capture nonlinear local behaviors. However, existing rule extraction methods suffer from inefficiency, incomprehensibility, infidelity, and not scaling well. Concerning security applications, they are not optimized regarding the decision boundary, data types and ranges, classification tasks, and dataset size. In this article, we propose CapsRule, an effective and efficient rule-based DL explanation method dedicated to classifying network attacks. It extracts high-fidelity rules from the feed-forward capsule network that explains how an input sample is classified. Using precomputed coupling coefficients, the training phase overlaps the rule extraction process to increase efficiency. The activation vector of a capsule can represent semantic intelligence about the attributes of the input sample. The rules extracted from CapsRule address the major concerns of network attack detection. The rules: 1) approximate the nonlinear decision boundary of the underlying data; 2) reduce the number of false positives significantly; 3) increase transparency; and 4) help find errors and noise in the data. We evaluate CapsRule on the CICDDoS2019 dataset that contains over a million of the most advanced Distributed Denial-of-Service (DDoS) attacks. The extensive evaluation shows that it generates accurate, high-fidelity, and comprehensible rules. CapsRule achieves an average accuracy of 99.0% and a false positive rate of 0.70% for reflection- and exploitation-based attacks. We verify that the learned features from the rulesets match our domain-specific knowledge. They also help find flaws in the dataset generation process and erroneous patterns caused by attack simulators.

Analysis of User Experience of the CapCut Application in Generation Z for Social Media Content Using the User Experience Questionnaire Method

Purpose: In the midst of these dynamics of change, research, development and application of technology continues to be the main focus in efforts to achieve progress and efficiency in various sectors of life. Generation Z has been the primary architect of cultural and behavioral change on social media. One of the most prominent characteristics of Generation Z is their desire to create "viral" content on social media. Content created using CapCut often uses interesting video and audio effects, such as progress effects, dry effects, music effects, and so on. This application has various features that make it easier for users to create video content, such as video effects, audio and animation. This shows that generation Z tends to use the CapCut application to create and edit video content that they share on social media. This research was conducted based on a phenomenon that has recently occurred, where many generations Z want to create content on social media using the CapCut application and also from several previous studies that have been conducted which are still lacking in understanding CapCup user satisfaction as a medium for creating content for Generation Z. and from several interviews the author conducted with CapCut application users. Method: This research uses the user experience questionnaire (UEQ) method with six (6) variables, namely attractiveness, efficiency, clarity, dependability, stimulation and novelty. Dr. Martin Schrepp developed a special tool that can be used to analyze UEQ questionnaire results, namely the UEQ Data Analysis Tool. The UEQ Data Analysis Tool is in the form of an Excel application which can be obtained by downloading it directly from the official https://www.ueq-online.org/ website This study employs a quantitative research strategy. This study does not know the exact number of the population to be studied. So, the sample size was calculated using the Lemeshow formula, a survey was conducted on 96 users of the Capcut application. Result: Based on the results of the discussion regarding user experience, specifically Generation Z, in the CapCut Application using the User Experience Questionnaire (UEQ) method, conclusions can be drawn from the 6 variables in the UEQ used, the 6 variables obtained positive evaluation values, namely the Attractiveness (mean 1.177), Perspicuity variables. (mean 1.109), Efficiency (mean 1.109), Dependability (mean 1.159), Stimulation (mean 1.151) and Novelty (mean 0.763) with the highest evaluation value on the Attractiveness variable. 2. Based on the benchmark results, the values obtained for the Attractiveness variable were 1.18, Perspicuity 1.11, Efficiency 1.11, Dependability 1.16, Stimulation 1.15, and Novelty 0.76. Each variable gets an Above Average value (above the average). However, there is still potential for improvement to achieve standards of perfection desired. Users provided invaluable feedback and suggestions, highlighting the need for improvement. Novelty: This research provides 2 recommendations based on the results of evaluations using UEQ, which are expected to help in improving and improving the quality of the CapCut Application in the future.

Minding the local slot: municipalities as drivers of trust in public institutions

ABSTRACT Political theory advocates the centrality of trust for democratic legitimacy and stability. It holds that democracy works best if citizens trust governance institutions. From this standpoint, we argue that the local political arena is conducive to nurturing trust, for onward projection onto national institutions. Using a mixed-method approach to a Ghana case study that combines in-depth interviews with regression and a propensity score matching technique, we demonstrate the centrality of proximity as a trust-building mechanism. We show that proximity to elected officials and local institutions facilitates inclusion and participation – and brings the otherwise distant state closer to the local population. Positive experiences with municipal structures – the most proximate of all state institutions – help build positive evaluations of the national government. Processes that deepen participatory platforms and inclusive decision-making in local arenas will furnish governments with a legitimacy and democracy dividend.

How emoji make meaning and enact ambient affiliation: a social semiotic account of emoji-text relations in TikTok comments

ABSTRACT This paper explores how emoji make meaning with language in TikTok comments. It offers a social semiotic account which models emoji-text relations as a system of convergence, involving three kinds of semiotic relations: ideational concurrence, interpersonal resonance, and textual synchronicity. The paper focuses in detail on the comment feed of a TikTok lip-sync video which uses audio from Julia Gillard's iconic misogyny speech. It considers the role that emoji pfhgilay in enacting ambient affiliation in these comments, whereby users share positive evaluation of the TikTok Creator and express alignment with values relating to modern feminism. The work is grounded in previous corpus-based studies by the authors of the social functions of emoji across a range of social media platforms.

An evaluation of the racial equity of the actuarial Family risk assessment instrument used in Queensland, Australia

BackgroundRisk assessment instruments used in child protection to guide intervention decisions should be equitable. To be considered equitable, two criteria are necessary: instruments should avoid discriminatory logic and display comparative validity for children of different races. Empirical evidence about the equity of risk assessment instruments is limited. Objective: To investigate the racial equity of a widely used risk assessment instrument, the Structured Decision Making Family Risk Assessment (FRA). Participants and setting: Administrative data were obtained for all children subject to investigation in Queensland, Australia in 2018, for whom an FRA was completed (n = 17,851). MethodsRelationships between FRA items, race, and recurrence (subsequent investigation within 12 months) were explored using crosstabulations and Cox Proportional Hazards. Accuracy of FRA recommendations and practitioner decisions were compared using sensitivity and specificity for Indigenous and non-Indigenous children. ResultsMost FRA items predicted race better than recurrence. Differences in recurrence by race were only partially explained by FRA items. The FRA produced high rates of false positives for Indigenous children (incorrectly classifying 48.9% of children who did not recur compared to 31.7% for non-Indigenous children) and high rates of false negatives for non-Indigenous children (incorrectly classifying 59% of children who did recur compared to 39% for Indigenous children). Practitioner discretion did not mitigate inequitable FRA recommendations. ConclusionsThe FRA failed both criteria of equity, discriminating indirectly by relying heavily on factors correlated with race, and demonstrating less accuracy for Indigenous children. High rates of false positives for Indigenous children exacerbate Indigenous overrepresentation in child protection.

Spatial heterogeneity: Necessary and feasible for revealing soil trace elements pollution, sources, risks, and their links

The source diversity and health risk of trace elements (TEs) in soil make it necessary to reveal the relationship between pollution, source, and risk. However, neglect of spatial heterogeneity restricts the reliability of existing identification methods. In this study, spatial heterogeneity is proposed as a necessary and feasible factor for accurately dissecting the pollution-source-risk link of soil TEs. A comprehensive framework is developed by integrating positive matrix factorization, Geodetector, and risk evaluation tools, and successfully applied in a mining-intensive city in northern China. Overall, the TEs are derived from natural background (28.5 %), atmospheric deposition (25.6 %), coal mining (21.8 %), and metal industry (24.1 %). The formation mechanism of heterogeneity for high-variance TEs (Se, Hg, Cd) is first systematically deciphered by revealing the heterogeneous source-sink relationship. Specifically, Se is dominated (76.5 %) by heterogeneous coal mining (q=0.187), Hg is determined (92.6 %) by the heterogeneity of metal mining (q=0.183) and smelting (q=0.363), and Cd is caused (50.9 %) by heterogeneous atmospheric deposition (q>0.254) co-influenced by the terrains and soil properties. Highly heterogeneous sources are also noteworthy for their potential to pose extreme risks (THI=1.122) in local areas. This study highlights the necessity of integrating spatial heterogeneity in pollution and risk assessment of soil TEs.

The development of an emotion lexicon for spicy food flavor experience

The sensory properties of food are the most important source of food-induced emotional responses. Spicy flavor is characterized by burning, stinging, or tingling, which gives a unique flavor to the sensory experience of food. The aim of the current study was to develop an emotion lexicon to measure the emotional responses to spicy food flavor. In Experiment 1, a focus group of frequent (N = 30) and infrequent (N = 30) spicy food consumers were interviewed to generate emotion words after tasting spicy food samples. After semantic analysis, comparison with published emotion lists, and positive and negative evaluations, a lexicon of 33 emotion words (21 positive and 12 negative emotion words) was developed for spicy flavor experiences. In Experiment 2, by applying the rate-all-that-apply technique, a separate group of participants (N = 91) rated the intensity of emotions before and after eating various spicy foods in small portions using the emotion lexicon generated in Experiment 1. Validation of the emotion lexicon shows that the high and the low spicy preference groups can be distinguished by most positive words (19 out of 21) and 4 negative words. Furthermore, participants’ spicy eating habits were significantly predicted by the positive or negative emotions associated with the spicy flavor experience during food tasting. Overall, the emotion lexicon serves as a valuable tool for investigating the affective correlates of spicy flavor across diverse spicy preference groups and holds promise for broader application to various products.

Affording pragmatics-focused training for language teachers: The case of L2 Mandarin Chinese

This study reported the design and implementation of a 16-week graduate seminar on second language (L2) pragmatics offered for 14 graduate teaching assistants (GTAs) who were teaching various target languages as teachers of record at a US public university. Grounded in the explicit awareness-raising approach, the seminar was designed to increase the GTAs' pragmatic knowledge, promote their cross-cultural pragmatic awareness, and facilitate their teaching and researching of pragmatics. Specifically, the training comprised four modules: key concepts in pragmatics, cross-cultural pragmatics, L2 pragmatics, and instructional pragmatics. With the recent advances in technology, the guidelines and practices for effectively designing web-based pragmatic materials were also incorporated. One of the GTAs, who was a native speaker of Mandarin Chinese and taught the language in the program, was observed as a focal participant to track the development of her pragmatic knowledge and application. Overall, the participants' positive evaluation ratings and comments on the seminar, as well as the focal Chinese GTA's demonstrated knowledge and application in pragmatics over time, suggest that the pragmatics-focused training is beneficial to cultivate the GTAs' professional knowledge and qualities in delivering pragmatics instruction.

Product Review Reading and Rating Statistics: How Do They Affect Consumer Product Evaluation?

ABSTRACTMarketers are concerned about how consumers' readings of product reviews and product rating statistics affect product evaluations. Previous studies generally regard product review content and rating statistics as affecting product evaluations independently. This may not be true. Typically, consumers enter a review section with pre‐existing positive expectations about a product. When they see a negative average rating in this section, their expectancies are disconfirmed. Their surprise stemming from the disconfirmation makes them read the reviews more carefully. Thus, review reading affects product evaluation more strongly when viewing a negative average rating. Conversely, a positive average rating results in expectancy confirmation, which weakens the effect of review reading. An eye‐tracking experiment using a mock‐resort review section supported these predictions. These findings have implications for marketers in behavioral advertising, responding to reviews, and consumers writing reviews.

How Government Stereotypes Affect Life Satisfaction: a Good Government Matters More Than a Government That Does Good

Many studies have noted the close relationship between the government and people’s life satisfaction. However, little literature has paid attention to the role of government stereotypes. This research fills this gap using two large samples of Chinese residents. In the first-phase study, we explored the content and structure of government stereotypes with a data-driven approach. We found that the content of government stereotypes consisted of four clusters: positive evaluations, negative evaluations, things about government duties, and things about the government system. Further, the content of government stereotypes could be distinguished based on two orthogonal dimensions: the valence (negative vs. positive) and the degree of generality (particularized vs. generalized). In the second-phase study, we examined how various dimensions of government stereotypes were related to life satisfaction. We found that people with more positive government stereotypes were more satisfied with life. This association was more potent when government stereotypes were more generalized (i.e., a good government at a higher construal level) than particularized (i.e., a government that does good at a lower construal level). Both studies of this research were repeatable within the two large samples. This research provided a new perspective for the literature on the relationship between government and life satisfaction and the interventions to improve life satisfaction.

Salt reduction attempts in workers after specific food service facility guidance provided by a public health center: A case study at a worksite in Kawagoe City, Saitama Prefecture

Objective The Kawagoe City Public Health Center implemented a project to reduce salt intake through specific food service facility guidance in workplace cafeterias. Here, we report the study results.Methods The target worksite was company A, with approximately 270 employees, located in Kawagoe City, Saitama Prefecture. There were 214 participants (approximately 80%). The project was conducted from November 2019 to November 2021. The long-term goal was to decrease the number of hypertensive cases in the city. Project outcomes included decreased salt intake, urinary sodium/potassium ratio, and average blood pressure. The project aimed to improve the cafeteria menu, focusing on salt reduction by offering Smart Meals® and reducing the salt equivalents in all menus. The project output indicators included reduced amount of salt in cafeteria menu items, increased frequency of cafeteria use, increased positive evaluations of the cafeteria, and increased daily awareness of the need for salt reduction. Spot urine samples, blood pressure measurements, and self-administered questionnaire data were collected during annual physical examinations. The amount of salt in the cafeteria menu was evaluated by receiving monthly data from the food service company to which company A outsourced its cafeteria operations.Results The analysis included 102 individuals with complete data from to 2019-2021. Estimated salt intake (g/day) from spot urine decreased from 10.3±2.1 in 2019 to 9.8±2.4 in 2020 and 9.5±2.0 in 2021 (P=0.003). Systolic blood pressure (mmHg) decreased from 114.7±12.5 in 2019 to 111.7±12.1 in 2020 and 110.6±12.0 in 2021 (P=0.010). Compared to 2019, changes in dietary salt equivalents in cafeteria menus in 2020 and 2021decreased for set meals A and B, curries, and noodles (P<0.001).Conclusion We offered Smart Meals® and reduced salt equivalents in all workplace cafeteria menus. After 1-2 years, employees' salt intake and blood pressure levels were lower. These results provide implications for the implementation of food environment improvements in public health centers and other local government agencies to promote the Health Japan 21 (third term) strategy.

Awareness as a catalyst for sustainable behaviors: A theoretical exploration of planned behavior and value-belief-norms in the circular economy

This study explores the interplay of intrinsic and extrinsic factors influencing sustainable behaviours within the Circular Economy (CE) through the lenses of the Theory of Planned Behaviour (TPB) and the Value-Belief-Norm (VBN) theory. This objective was achieved by conducting a large scale survey in Brazil and using Composite-Based Structural Equation Modeling (cSEM) technique in conjunction with R software to analyze data and assess our research hypotheses. Our findings underscore the paramount importance of intrinsic factors—such as personal values, beliefs, and positive evaluations of sustainability outcomes—over external pressures like environmental laws and organizational policies in fostering sustainable actions. While increased awareness of the CE significantly enhances attitudes towards and the likelihood of engaging in sustainable behaviours, the study reveals that external pressures and perceived barriers, such as time, cost, and skill limitations, do not significantly deter those with a high level of awareness and positive sustainability evaluation from acting sustainably. Academically, the study enriches environmental psychology by extending TPB and VBN theories, advocating for a refinement of TPB to better account for contexts where personal values are stronger drivers than external pressures or immediate practical constraints.

Unveiling the dynamics of revisit intention and word-of-mouth: an attribution theory approach to Halal-friendly hotel attributes and service encounter evaluation

PurposeThis study examined the revisit intention of tourists in Muslim-friendly hotels in nexus with Halal-friendly hotel attributes (social environment, facilities, food and beverage, locals and staff, and services), corporate image, customer engagement, perceived value, and service encounter evaluation. It further examined the mediating role of corporate image, customer engagement and perceived value between Halal-friendly hotel attributes and service encounter evaluation.Design/methodology/approachUsing a structured survey instrument, 390 valid responses were gathered from international tourists who visited Malaysia. The collected data were analyzed using Partial Least Squares – Structural Equation Modeling (PLS-SEM) to test the assumed relationships.FindingsThe research shows that corporate image (CI), customer engagement (CE), and perceived value (PV) are directly influenced by Halal-friendly hotel attributes (HFHA) and exert influence on service encounter evaluation (SEE). Findings also suggest the mediating effect of CI, CE, and PV between HFHA and SEE. SEE further positively and significantly enhances the revisit intention and positive word-of-mouth.Practical implicationsThe findings of this study stipulate that hotel owners should ensure the presence of HFHA in their offers to retain their existing guests and ensure their positive communication towards potential visitors through developing a fascinating image, engagement, and lucrative value.Originality/valueGrounded on the attribution theory, this study contributes to the Halal tourism literature by exploring the role of Halal-friendly hotel attributes in enhancing the hotel’s image, customer engagement, and perceived value to enhance positive service encounter evaluation and revisiting intention for the hotel.

Phosphatidylethanol is a promising tool for screening alcohol consumption during pregnancy.

Prenatal alcohol exposure (PAE) is one of the leading causes of preventable developmental disabilities. A lack of objective screening methods results in an under-recognition of the phenomenon. Phosphatidylethanol (PEth) is a specific ethanol biomarker that reveals alcohol intake up to several weeks after alcohol use. So far, PEth has mostly been a tool for detecting moderate and heavy drinking. With lower PEth cut-offs, revealing even minor prenatal alcohol consumption is possible. We aimed to find out if a sensitive method for PEth analysis would give additional information about PAE and to assess the cut-off value for a positive alcohol result in prenatal screening. The study was an observational study of 3000 anonymous blood samples collected from the Helsinki University Hospital Diagnostic Center between June and September 2023. The Finnish Red Cross Blood Service received the samples originally for blood group typing and antibody screening as part of the prenatal blood screening program. We developed a sensitive PEth 16:0/18:1 analysis method using ultra-high-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) equipment after liquid-liquid extraction of PEth from whole blood. The lower limit of quantification was 1 ng/mL. PEth was ≥2 ng/mL in 5.2% of the cases, ≥8 ng/mL in 2.0%, and ≥20 ng/mL in 1.0%. The detection time of PEth can be several weeks, especially with low PEth concentrations and after heavy alcohol consumption. It remained unknown whether the positive PEth tests resulted from drinking deliberately during pregnancy or before pregnancy recognition. We suggest adding PEth 16:0/18:1 to a routine prenatal blood screening program with a cut-off of 2 ng/mL-and in positive cases, clinical evaluation and retesting in 2-4 weeks. In clinical settings, information on gestational week and alcohol consumption before pregnancy is relevant and needs to be considered when interpreting low PEth concentrations.

Aplicação da Plataforma Kahoot! Durante o Ensino Remoto na Pandemia por COVID-19

The pandemic we are facing has generated the need for changes in the teaching process of Higher Education institutions. Remote teaching has become a reality, directly impacting pedagogical training. Digital applications with themes focused on teaching and learning, such as Kahoot!, have become tools to stimulate student participation and engagement during classes. In this study, students were subjected to a quiz on subjects directly related to the classes through the use of Kahoot!. At the end of the semester, a questionnaire was applied through an online form, addressing its use as a revision tool. Acceptance was generally satisfactory and positively evaluated by students. However, the difficulties related to its administration are challenges that still need to be overcome, aiming to maintain the quality of teaching. The positive evaluation of students is seen as an important indicator to guide the actions of the teacher in future practices that adopt digital tools as an integral part of the teaching of traditional disciplines.
