Student misconceptions occur because students build their own concepts from their own environment without the help of experts, therefore, students' initial knowledge that is not the same as expert opinion is what causes misconceptions. This study aims to produce an interactive conflict-based cognitive e-module to remediate misconceptions and improve students' understanding of concepts about force. This type of research is design or development research using the Plomp model, with 3 phases, namely; (1) preliminary research, (2) development phase and (3) assessment phase. This research is limited to the expert review development phase. The preliminary research was conducted by reviewing 5 journals about the problems of students' misconceptions on the concept of force. At the development phase, e-module design, self-evaluation, and expert review of the e-module prototype are carried out. The data were obtained from the self-evaluation assessment sheet by three researchers and the validation sheet by three physics lecturers. Based on the preliminary research, it was found that there were problems in understanding the concept of students in the material of force. Therefore, a cognitive conflict-based emodule was designed that could improve students' conceptual understanding. The self-evaluation results of the emodule design showed that the e-module design was in the very good category with an average of 93.4. The results of the expert's study showed that the e-module design was in a very valid category with an average of 85.6.
The Critical Approach in Al-Muazana “In the Modern Equalization of Criticism” (A Criticism of Criticism)
Authors: Al-Huwairini Amal Abdullah
Published: October 2021

The research was directed to the modern critical books that received the book “Al-Muazana bayna Abu Tammam and Al-Buhturi” by Abu Al-Qasim Al-Hassan bin Bishr for Al-Amidi (370 Ah) to answer the main question: what are the main features of criticism in Al-Muazana book in contemporary criticism books? The study aims to reveal the views on the critical approach of Al-Amidi, and then trying to reconcile the opinions of contemporary critics that discussed the method of Al-Amidi in his book, one of them was the first book in which applied criticism appeared. One of contemporary critics’ opinion was that it was characterized by investigating the opinions of the old critics about the Poetry of the Poets, a book in which objectivity was achieved in equalizing and neutrality. Contemporary critics almost agreed that Al-Amidi was characterized by planning his approach in the introduction to his book and its application. The most important results: Al-Amidi explained the poetic thefts attributed to Al-Buhturi and Abu Tammam simultaneously. He explained the many poetries that Abu Tammam took from others with his many archives. Contemporary critics pointed out that Al-Amidi was not interested in the linguistic errors of poets, and he argued that there were many mistakes of ancient poets. Contemporary critics differed about Al-Amidi’s intolerance of the poet Al-Buhturi and all his arguments.
Evaluation of Wadjda: A Comparative Discourse Analysis of Western and Saudi Movie Reviews
Authors: Saleh Almohaimeed Maram
Published: October 2021

Since people are showing more interest recently in movies and as movie reviews of the same movie could vary in the degree of their objectivity, this paper seeks to answer why movie reviews may differ in their evaluation of the same work. To this end, a critical discourse analysis using Fairclough’s three-dimensional framework and Martin and White’s attitude framework is carried out to analyze two reviews of the Saudi movie Wadjda, one written in English by a western critic, and the other is Arabic written by a Saudi critic. The textual analysis of attitudinal expressions shows that the English text maintains an even distribution between the negative and positive expressions, and most of the negative expressions do not assess the aspects of the movie but rather the Saudi society. In the Arabic text, however, the negative expressions outnumber the positive ones, and they are mostly related to the movie and the director. Using Fairclough’s framework, the author explains the findings of the textual analysis of the English review and the critic’s avoidance of negative evaluation as a result of Eurocentrism and the way the western media represent Arabs and Muslims. However, the negative appraisal of several movie aspects found in the Arabic review could be seen as a result of the critic being part of the society and, thus, not distracted by the social issues.

Published: October 2021

South Sumatra Province experiences forest and land fires every year. Peatland and human activity have caused this region to be more vulnerable to fire. In this study, we used annual mapping to describe the history of forest and land fires in Ogan Komering Ilir (OKI) District of South Sumatra to analyze fire trends during the 2015-2019 period. Hotspot data were obtained from Terra/Aqua MODIS satellite imagery at all confidence levels. Burned areas were identified using the Normalized Burn Ratio (NBR) Index, with data sources from Landsat 8 satellite imagery obtained from the USGS (United States Geological Survey). The highest number of hotspots were detected in 2015 (33,748), with 72% was located on peatland. Historical analysis of hotspot numbers, shows that the majority of burning occurs in September and October. This indicates that prevention activities must be carried out more intensively before these months. Linear regression between annual hotspot numbers and rainfall was not significant. Hotspots indicative of forest and land fire in OKI District were more influenced by human activities. The largest burned area (993,999 ha) occurred in 2015. The 2015 El Niño event triggered drought and worsened forest and land fires in Indonesia. Although no El- Niño conditions occurred in 2016-2018, fires continued to occur in OKI District, showing their independence from extreme drought. The fires occurring on peatlands burned a large area during 2015-2019 indicating that forest and land fires management must become a top priority in OKI District

Published: October 2021

This research aims to synthesize polyurethane membrace from avocado seed oil as a source of hydrixyl (-OH) and hexametylhene -1.6-dissocyanate (HDMI) as a source of isocynate (-NCO). The oil were extracted from avocado seeds at temperature of  60-80oC for 2 hours using n-hexane solvent. The results of FTIR spectrum analysis from avocado seed oil showed that there were -OH clusters absorption on the wavelength number of 3393.819 cm-1, thus this oil can be used to synthesize polyurethane membrane. The isocyanate composition, time and temperature during synthesis process of polyurethane membrane were varied. The polyurethane membrane were moulded in petri dishes, then heated up for 48 hours on the temperature of  70oC, and finally taken out from its mould. The characteristics of the polyurethane membrane from avocado seed oil are brown in colour, homogenous, elastic, solid, transparent and shaped like a membrane. The measurements from FTIR spectrum showed that the -NCO clusters are no longer present. This condition happened because there were no more absorption in the wavelength number of  2270 cm-1 . It can be concluded that the isocyanate has completely reacted during polymerization and the curing process, thus urethane was created in the 1699,965 cm-1 absorption which was the urethane C=O clusters absorption.
”Vi gör så gott vi kan”

Published: October 2021

This study aims to explore how teachers in school-age educare describe their conditions for and work with offering learning and development support to pupils. The study is based on a web survey with both fixed and open response options. The following research questions are posed: How do teachers in school-age educare describe their conditions for working with supporting pupils? How do teachers in school-age educare describe their assignment to support pupils? And, finally, in what way can school-age educare’s social pedagogical tradition be a resource when supporting pupils? The results indicate the existence of both staff and resource shortages in school-age educare centres. Despite this, the staff describes their work to include all pupils as a reorganisation of the physical and the social learning environment in the centres. The respondents report several reasons for this: flawed premises, large groups of students, untrained staff and insufficient cooperation between different staff groups. However, the respondents’ answers also mention special educational elements, even if social adaptations are predominant and the after-school leisure centre's supplementary assignment to the school is primarily characterised by relational and social support for students. Finally, the answers also indicate the need for more competence and knowledge in offering optimal support to students from a compensatory perspective. These answers reveal an ongoing conflict between the leisure centre’s traditional care responsibility and its newly gained educational responsibility for the leisure-centre staff.

Published: October 2021

Conodont assemblages from shallow platform carbonate strata of the Dyer Formation in northwestern Colorado indicate that the unit spans the Devonian–Carboniferous transition, and include four new taxa, described herein. The underlying Parting Formation and most of the Broken Rib Member of the Dyer Formation are in the Palmatolepis expansa Zone. The upper portion of the Broken Rib Member and the lower part of the Coffee Pot Member of the Dyer Formation are in the Bispathodus aculeatus Zone to the Bispathodus ultimus Zone, and associated with an ~6‰ positive δ13C shift identified as the end-Devonian Hangenberg excursion. Upper Coffee Pot Member conodonts are equivocally Tournaisian, and cap the δ13C excursion. Collectively, these observations suggest that the Devonian–Carboniferous boundary is in the upper Coffee Pot Member of the Dyer Formation, and thus the overlying Gilman Sandstone is Carboniferous.

Authors: da Costa Fhelen Debbie , Prashant G. M. , Sushanth V. H. , Imranulla Mohamed , Prabhu Allama , Kulkarni Sampada Suresh
Published: October 2021

Introduction:

Oral health is governed by a multitude of factors and of importance among these is diet and nutrition. Patients need to be made aware of the effect diet and nutrition has on their oral health. Patients should also be encouraged to reduce the frequency of intake of sugary foods. Dentists need to have adequate knowledge regarding diet and nutrition and its effects on oral health. Dental students can be targeted at an early stage as they will be the beacons of dentistry and carry on the knowledge into private practice.

Aim:

The aim of the study was to assess the knowledge of the undergraduate dental students regarding diet and nutrition and its impact on oral health and to assess their attitude and practice towards the same.

Methods:

A cross sectional questionnaire based study was carried out among 203 undergraduate students (122 third BDS, 22 Final BDS and 59 Residents) from dental colleges in Davangere, Karnataka. The responses were subjected to statistical analysis using SPSS (Statistical Package for the Social Sciences) version 22 and the tests used were Frequency distribution and Pearson Chi-Square test.

Results:

Most of the participants (82.3%) were aware that sucrose is the most cariogenic sugar. 84.2% of the students knew the type of food that helps in preventing dental caries and strengthening the periodontium, yet only a few (19.2%) were able to correctly choose the most anticariogenic food among the options.

Conclusion:

While most of the students were aware of the basic knowledge of diet and nutrition and its effect on the oral health, their attitude and eagerness towards the concept should be nurtured through extensive and in detail addition of diet in the curriculum to ultimately help patients maintain a better oral hygiene and prevent oral diseases.
Dionysian Eros or Erotic Dionysus? Sources and Meanings of Hybridization in the Bacchus Mosaic at the Naples Museum
Authors: SEVİLLA-SADEH Nava
Published: October 2021

The splendid mosaic exhibited at the Archeological Museum in Naples presents two enigmatic hybrid images: a feline composed of a tiger and a lion, and a figure that combines the characteristics of both Dionysus and Eros. This study seeks to decipher the hybridization of these two mighty gods of the Roman world, Dionysus and Eros, as presented in the Naples museum mosaic. The main assumption is that two features link these two gods: madness, and the illusion of merging with the Divine. The hybridization of the two gods would seem to strengthen the significance of both and of their role as gods of transcendence, as revealed through an examination of Classical literary and philosophical sources.
Magnetorheological Elastomer (MRE) based Torsional Vibration Isolator for application in a Prototype Drilling Shaft
Authors: Syam Thaer Mahmoud , Bin Abdul Muthalif Asan Gani
Published: October 2021

Magnetorheological Elastomer (MRE) is a type of smart composite material consisting of a polymer matrix embedded with ferromagnetic particles. In the presence of an external magnetic field, its mechanical properties, such as stiffness, changes make it attractive in vibration isolation applications. Unwanted vibration in machines can cause severe damage and machine breakdown. In Qatar, the extraction of the natural gas from the ground requires sophisticated drilling machines. In this work, a semi-active vibration isolator using MRE is proposed for a potential application in a drilling system to isolate the torsional vibration. MRE was fabricated with a 35% mass fraction (MF) consisting of silicon rubber and iron particles. It was fitted with aluminum couplers and attached to the shaft (drill string) to study its efficiency in vibration isolation under a magnetic field. Two tests were conducted on the drilling prototype setup used in this work; the first test was a hammer impact test. The torsional transfer function TTF analysis showed that the system's natural frequency has shifted from 13.9 Hz to 17.5 Hz by the influence of increasing magnetic field around the MRE. The results showed that the continuous rotational vibration amplitude of the prototype is attenuated by more than 40%.
Parametric Study on Moment Redistribution of Fiber Reinforced Concrete Continuous Beams with Basalt FRP Bars
Authors: Abushanab Abdulrahman Hamdi , Alnahhal Wael I
Published: October 2021

The state of Qatar bears harsh environment and coastal conditions which stand for most of the year. As a result, steel-reinforced concrete structures are subjected to rapid corrosion and deterioration. Therefore, there is a necessity to replace the conventional steel reinforcement by fiber-reinforced polymers (FRP) bars. Apart from FRP bars’ corrosion resistance, their strength to weight ratio is higher than steel reinforcement which makes the FRP bars a viable alternative to steel reinforcement. Continuous concrete beams are commonly used elements in structures such as parking garages and overpasses. In such structures, forces could be distributed between the critical sections after cracking. This phenomenon is called moment redistribution. It reduces the congested rebars in connections and enhances the ductility of the members. However, the linear-elastic behavior of FRP materials makes the ability of continuous beams to redistribute loads and moments questionable. This study aims to investigate the capability of moment redistribution of basalt fiber reinforced concrete (BFRC) continuous beams reinforced with basalt FRP (BFRP) bars. Ten reinforced concrete (RC) continuous beams of 200 x 300 x 4000 mm were tested up to failure under five-point loading. The main investigated parameters were the reinforcement ratio (0.6rb, 1.0rb, 1.8rb and 2.8rb; where rb is the balanced reinforcement ratio), stirrups spacing (80 and 120 mm) and volume fractions of Basalt-macro fibers (BMF) (0.75 and 1.5%). A parametric study was then conducted using a validated finite element (FE) model to extend the investigated parameters that may affect the moment redistribution of RC continuous beams. It was concluded that moment redistribution occurs in beams that have at least a ratio of bottom to top reinforcement of 0.3.
Biodiversity of Arbuscular Mycorrhizal Fungi in Plant Roots and Rhizosphere Soil from different arid locations of Qatar
Authors: alrajhi Khazna
Published: October 2021

Recently more attention or interest has been developed towards the role of Arbuscular Mycorrhizal Fungi (AMF) in plant growth. Qatar, which is a part of the Arabian Gulf region, is mostly arid with hot and dry climatic conditions. The current research aims to investigate the Occurrence, species composition and abundance of AMF in Qatar, for which rhizosphere soil samples and roots of 16 plants belonging to 12 families from eight locations were collected. The AMF from different samples were identified based on the sequencing of the PCR product of the amplified conserved ITS region. The results showed that the AMF infection rate varies with location and plant species. Tamarix aphylla recorded the highest AMF infection rate (100%), followed by Blepharis ciliaris (98%) and Sporobolus ioclados (92%). AMF spore counts per 100g of soil ranged from 29.3 spores in Blepharis ciliaris to 643 spores /100g in Fagonia indica. The spore counts per location is variable and the range was 29.3 to 643/100g soil, however, no correlation has been detected between root colonization rate and spore counts. While all AMF identified at species levels were reported in other regions this research will be the first to investigate the AMF biodiversity from Qatar. However, new species are still expected since some were identified only at higher taxonomic levels. Claroideoglomus drummondii and Rhizophagus irregularis were the most widespread species while Claroideoglomus claroideum and Diversispora aurantia were the less present. This study provides comprehensive biological data about taxonomy, distribution and prevalence of AMF in Qatar soil, which opens new research towards developing its future applications for environmental conservation and sustainable agriculture.

Published: October 2021

The produced water from natural gas production process in the North field offshore is considered as the largest wastewater volume in Qatar, which could be potentially used for clean water resources for the industry as well as for some other domestic uses, if it is treated properly. This research aims to study the physical and chemical characterizations of the produced water from the North field and examine the removal of major inorganic and organic pollutants and heavy metals from the PW by using different treatments method such as using the sand filtration, activated carbon filtration and modified activated carbon filtration. The physical and chemical characterization of produced water was examined followed by treatment through sand filtration coupled with activated carbon and microemulsion modified activated carbon techniques. The results of characterization showed that the produced water had high concentration of COD, TOC, BTEX and various metals. After sand filtration, considerable reduction in TSS and COD was achieved. Furthermore, BTEX were also removed by more than 93% except for toluene. However, sand filtration was not enough to remove most of the metals and ions. Therefore, further treatment was done through activated carbon and modified activated carbon and their treatment efficiency was compared. Both techniques were able to achieve higher removal efficiencies for BTEX, metals and ions. Thus, the treated water was free from all major pollutants of PW and can be considered suitable for reuse at industrial application. Further studies and applications could be applied on produced water such as studying the biological characterization and applying biological treatment processes.

In July 2021, regular flights of the Unity rocket plane and the New Shepard rocket with the First Step capsule took place. For the first time, both vehicles had passengers on board. The first of them rose to a height of about 86 kilometers, the second – "stepped" over a hundred-kilometer line. The events are long-awaited and, in a certain sense, significant. The media was quick to call the incident the beginning of the "era of space tourism". However, this name does not quite accurately reflect the essence of this phenomenon. Furthermore, it is impossible to consider the participants of these missions as cosmonauts. But, in any case, this is a new stage in technology development. The article provides brief information on the flights that took place. An attempt was made to understand the terminology issues. An assessment of the new phenomenon and its influence on the further development of aviation and cosmonautics is given.

The formal issues are related to the means through which the legislator made the changes - the emergency ordonnance, as well as the qualification of these measures as temporary criminal law. The essential changes are aimed at art. 352 Criminal Code, the crime of „thwarting the repression of diseases”. The new statues sanction the failure to comply with measures of quarantine and hospitalization, notions which have been used differently by the legislator, depending on the legislative instrument that he used. The crime becomes one of abstract danger, which could raise issues regarding the significant extension of the incrimination. The punishment has been increased and aggravated forms have been added. In the case of the latter, they constitute crimes of material result, and not abstract danger. This, in turn, means that the crime, in its basic form, is an „obstacle-crime”. Forms are aggravated in regard to the degrees of guilt of the result of the crime. Other changes are aimed at the crime of „false declarations” and „the failure to declare information”, enshrined in art. 326 and 3521 of the Criminal Code. In this case, the legislative technique is questionable, as well as the terminology, which may be lacking predictability. Such is the case of the general notion of „essential information”. It remains to be seen whether the new crimes of aggravated forms of preexisting crimes will prove efficient in the fight against the pandemic.
Cât de militară este ordonanța militară?
Authors:   Institutul de Științe Criminale și Justiție, Universitatea din Bordeaux, DIMA Bogdan
Published: October 2021

In this article, I shall discuss the legal nature of the military ordinances issued by the Minister of Internal Affairs during the state of emergency, in accordance with Emergency Ordinance no. 1/1999 concerning the regime of the state of siege and the regime of state of emergency (EOG no. 1/1999). My advice is that no one should not fall for the term „military”. In fact, military ordinances issued during the state of emergency by the Minister of Internal Affairs are normative administrative acts facilitating the execution of EOG no. 1/1999 provisions. As a result, they could be contested for legality in front of the judiciary, but they cannot be suspended, in accordance with art. 5 para. 3 of the Law no. 554/2004 concerning the judiciary control over the administrative acts.

The study proposes to examine – in the light of the challenges raised by the COVID-19 pandemic – whether and how States can suspend the performance of international law obligations in a situation of emergency. The study focuses on patterns of treaty clauses that may allow for certain exceptions (while the circumstances precluding wrongfulness are subject to a subsequent study). On one side, the research examines the GATT exceptions provided in articles XX (general exceptions) and XXI (security exceptions), and on the other side, the patterns of clauses within Bilateral Investment Treaties. Relevant case-law of WTO panels, appelate bodies and of investment arbitration tribunals is also examined.
Închisoarea noastră cea de toate zilele. Despre pedepse și alte sancțiuni
Authors:   Facultatea de Drept, Universitatea din București, RIZOIU Radu
Published: October 2021

Starting with the harsh consequences of the lockdown, the paper looks into the typology of sanctions. Despite their resemblance in the form of restrictions brought to personal freedom, penalties are different to preventive measures or safety policies. As such, each of these State-led interventions into the personal liberty serves distinctive purposes and should not be confused to one another. Based on this classification, the paper then applies the test to the home arrest and the proposed new rules to make it the penalty of choice for the white collar criminals.
Adaptarea activității de judecată în materie civilă în contextul pandemiei și ulterior acesteia

The SARS-COV2 Pandemic represents a challenge for the Romanian justice system. The traditional approach, where all parties are summoned physically in the court room – and even at the same time –is not sustainable any longer. New procedural rules are necessary. Different hours for different cases is already a reality in many courts and it should become the day-to-day rule. In addition, trials through videoconferences and in written proceedings only should be made possible by the Civil Procedure Code. At the same time, Romania should begin the lengthy process of implementing the electronic file.
Ce ție nu-ți place altuia nu-i face: Despre regula de aur în pandemie
Authors:   Facultatea de Drept a Universității din București, RIZOIU Radu
Published: October 2021

The paper develops on John Rawls ‘golden rule’ and applies it to the current pandemic situation. In doing so, it starts with the presentation of a trivia case to illustrate the double standard we tend to apply when it comes to our actions as compared to the others’. We always ask to others to obey the rules, while we consider ourselves smart enough to decide on a case by case basis. This kind of attitude has a special effect when the persons ignoring the rules are exactly those who issued them. The paper tries to address the concern that following the rules should be a way of life and, in the same time, to suggest that rules should emanate from bottom to top (meaning they need to have a reasonable explanation to the public) rather than being imposed from top to bottom.

This article explores the topic of the death penalty and the arguments for and against it from the perspective of a questionnaire addressed to law students coming from the faculties belonging to the Law Faculties Hexagon in Romania. Without claiming to be a complete sociological study, the data regarding the 2201 respondents to the questionnaire, as well as the answers to the essential questions, provide a new and particular picture on perceptions regarding the death penalty in a country where, indeed, a reintroduction of this punishment is, at this time, impossible. We also carried out an analysis of the reasons that determine law students to position themselves in favor of or against the death penalty, given the need to reveal, from time to time, not only the percentage of people who declare themselves in favor of the death penalty, but also of the main arguments that represent the core of the discussion at a certain point in the course of history.

The paper analyses the crime of bodily harm provided by art. 194 par. (1) let. c) Criminal Code, consisting of battery or other acts of violence which caused a serious and permanent aesthetic injury. Although this crime has always existed in the Romanian law, this immediate consequence previously being called disfigurement, its renaming in the Criminal Code which entered into force in 2014 gave rise to new discussions, including those on the compatibility of the regulation with the rule of law and the principle of equality before the law. After analysing these aspects, the article reviews the case law of national courts, by explaining the objective and subjective criteria that outline the solution of classifying a deed as the crime of bodily harm. Subsequently, some particular hypotheses are analysed, such as the loss of teeth, the loss of an eye, the existence of scars or the tattooing of the victim, which highlight the existing variable jurisprudence in this matter.
Hierarchy-Enhancing Misinformation: Social Dominance Motives Are Uniquely Associated With Republicans’ Belief In and Sharing of Election-Related Misinformation
Authors: Lees Jeffrey Martin , Parker Victoria Ashley
Published: October 2021

The aftermath of the 2020 US Presidential election saw a deluge of election-related misinformation which falsely asserted that the election was “stolen” from Donald Trump. Since then a majority of Republicans have consistently expressed belief in this misinformation, despite no evidence for its veracity and its motivating role in the January 6th, 2021 attack on the US Capitol. Here we present evidence, using a repeated-measures design (N = 355) across a highly generalizable stimulus set, that Republicans’ support for 2020 US election-related misinformation and willingness to share it on social media are uniquely associated with social dominance motives, along with conspiracy mentality and party identification strength. We find little evidence that right-wing authoritarianism is associated with the belief in or sharing of election-related misinformation, and that cognitive reflectiveness is only associated with sharing, but not belief. We introduce the theoretical lens of Hierarchy-Enhancing Misinformation to interpret these findings, arguing that election-related misinformation is best understood as a functional mechanism by which group-based dominance hierarchies are socially and psychologically reinforced.
Do individuals combine different coping strategies to manage their stress in the aftermath of psychological contract breach over time? A longitudinal study (Article accepted for publication by the Journal of Vocational Behavior)
Authors: Achnak Safâa , Vantilborgh Tim
Published: October 2021

This study examines the dynamic interaction between perceptions of psychological contract breach (PCB), negative emotions, and stress over time. Additionally, we determine if individuals could be differentiated based on coping profiles, and further assessed whether emotional and stress reactions to PCB over time varied as a function of these profiles. Using a longitudinal design, a sample of 1077 employees working in various industries completed a monthly questionnaire for six consecutive months reporting their perceptions of PCB, negative emotions, stress reactions, and ensuing coping mechanisms. Results from the latent growth analysis revealed that individuals confronted with increasing levels of PCB over time reported growing stress following their escalating negative emotions. Moreover, the latent profile analysis of coping performed in two randomly selected subgroups revealed that there were three coping profiles within our sample (i.e., low copers, average-problem-focused copers, high-problem-and-emotion-focused copers). We found evidence for different trajectories of negative emotional and stress reactions to PCB over time depending on the different coping profiles. As such, individuals endorsing high levels on all three types of coping but relatively higher levels on emotion-focused and problem-focused coping compared to avoidance coping were associated with the most favorable psychological functioning over time (i.e., no escalation in emotional and stress reactions to PCB over time). In contrast, individuals endorsing low levels on all three types of coping reported less favorable psychological functioning in the long term. We discuss theoretical and practical implications of our findings and offer recommendations for future research.
