Labor de la criminalística de campo en Panamá
Authors: Avila Arrocha Ana G.
Published: May 2021

El trabajo de criminalística de campo no es muy claro para muchas personas que se encuentran en el ámbito de la administración de justicia y para la sociedad, por lo cual es necesario realizar una descripción de la labor que se realiza y los objetivos que se pueden cumplir por medio de la inspección técnica ocular. La inspección técnica ocular ayuda a la investigación de los hechos delictivos, fija el lugar de los hechos y nos permite recolectar información de la escena del delito, que nos permite orientar futuras decisiones en base a lo que probablemente sucedió en el hecho. La criminalística de campo es la primera aplicación científica que se proporciona a la investigación de un hecho delictivo, por lo cual es importante conocer lo que se realiza. La innovación y modernización ataca a todos los sectores y en especial a la criminalística que se encuentra en constante evolución, por lo cual es significativo evaluar los procesos y técnicas que se aplican para actualizarlos y mejorar la labor que se realiza y de esta manera obtener mejores resultados.
Türkçe Sözlü Hafif Batı Müziğinin Oluşumunda Fransızcadan Çevrilen Şarkılarda ‘Yerli Ve Millî Aşk’a Dair
Authors: OKYAYUZ Şirin , KAYA Mümtaz
Published: May 2021

Çalışmada, 1968-1969 yılları arasında Fransızcadan Türkçeye çevrilmiş olan pop şarkılarında aşk temasının aktarımı ve erek ürünlerde yansıtımı incelenmiştir. Çalışmanın ilk kısmında şarkıların kültürlerdeki öneminden yola çıkarak belli bir döneme, gerçekliğe ve bulgulara ışık tutabilecek kaynaklar olgusu üzerinde durulmuştur. Farklı disiplinlerden araştırmacıların görüşleri derlenerek şarkı çevirisi incelemelerinde disiplinlerarası yaklaşım ve bakışın öneminin altı çizilmiştir. Takip eden bölümde ise çeviribilim altında şarkı çevirisi alanyazınına değinilmiştir. Ayrıca, incelenecek bütünce verilmiş ve ayrıntılandırılarak açıklanmıştır. Bir sonraki bölümde ise benimsenen araştırma yöntemi açıklanmıştır. Özünde kaynak ve erek metin karşılaştırmasını içeren ampirik çalışmanın bulgular kısmında bütüncedeki veriler ilk önce tasnif edilmiş, ardından da kısa örneklerle açıklanmıştır. Yorum ve tartışma başlığı altında bulgular sosyal, politik, tarihsel ve benzeri bakış açılarından ele alınmış ve bir çerçeveye oturtulmaya çalışılmıştır. Sonuç bölümünde ise, aranjmanlar dönemi diye adlandırılan dönemde şarkı çevirisi olgusuna üstsel bir bakış açısıyla yaklaşarak, verilere dayalı bazı sonuçlar ortaya konmuştur. Çalışmada ele alınan bağlamda şarkı çevirisinde yaratıcılığın ön planda olduğu, yerlileştirmenin ve bu şarkıları erek kültürde benimsetmenin öncelik olduğu savunulmuştur. Bu bağlamda şarkı çevirisi uğraşının bir kaynağı erek kültüre aktarmaktan çok erek kültürde popüler olacak bir ürün sunma uğraşı olarak görülmesi gerektiği ortaya konmuştur. Sonuç olarak, örneklenen türden çalışmaların kültürel tarih ve miras araştırmalarına katkısı üzerinde durulmuştur.
Mathematik lernen mit Hilfe von Videos. Analyse von didaktischem Aufbau und Nutzung von mathematischen Lernvideos außerhalb der Schule
Authors: Sina Wetzel
Published: May 2021

Auf YouTube gibt es kostenlose Videos mit den unterschiedlichsten Inhalten. Auch zu schulischen Themen findet man dort eine Vielzahl sogenannter Erklär- oder Lernvideos. Obwohl diese Videos bei Schülerinnen und Schülern sehr beliebt sind, beispielsweise als Hilfestellung beim Bearbeiten der Hausaufgaben oder unterstützend beim Lernen für einen Test oder eine Klausur, geraten insbesondere mathematische Lernvideos immer wieder in die Kritik. So lautet einer der Vorwürfe, sie würden nur oberflächliches Wissen vermitteln. Verlassen sich Schülerinnen und Schüler auf diese Videos als alleinige Informationsquelle und Lernressource, kann dies zu Problemen führen. Dennoch attestieren viele Schülerinnen und Schüler diesen Videos einen positiven Einfluss auf ihren Lernerfolg. Die vorliegende Arbeit ist in drei Teile gegliedert. Im ersten Teil wird das Thema Lernvideos aus theoretischer Perspektive vorgestellt und analysiert. So werden beispielsweise Kriterien für gute Lernvideos aus der Literatur zusammengetragen. Der nächste Teil widmet sich speziell mathematischen Lernvideos und untersucht, inwiefern diese einen Spezialfall darstellen. So wird beispielsweise überprüft, inwiefern erprobte mathematikdidaktische Konzepte wie die Winter’schen Grunderfahrungen auf Lernvideos übertragbar sind. Im Anschluss werden drei Lernvideos zum Thema Kombinatorik analysiert und verglichen. Im letzten Teil wird die Konzeption, Durchführung sowie die Ergebnisse einer explorativen Onlinestudie zu mathematischen Lernvideos vorgestellt, an der über 2.000 Schülerinnen und Schüler teilnahmen.

Public Examinations in Romanian Secondary Schools at the End of the 19th Century and the Beginning of the 20th Century
Authors: Caramelea Ramona
Published: May 2021

The article offers an historical perspective on examination in public secondary schools at the end of the 19th century and the beginning of the 20th century – a period of maximum expansion of secondary education. The first part of the article focuses on the institutionalization and formalization of examination practices, while the second one discusses the shaping of the examination as a topic, following the discourses produced by different social actors. In the second half of the 19th century, the school was perceived as an instrument for social mobility based on the meritocratic ideal and as an element of national and state building, being given the role of inoculating a national identity. Within this socio-educational context, secondary schools represent the recruitment pool of the administrative elite and ensure the acquisition of cultural capital necessary for accessing various positions, all these aspects shaping the social functions of exams. The documentary analysis based on archival sources revealed a nuanced social perspective, in which the teaching staff and the parents give new meanings to the concept of examination and design new functions for exams.
De la separatism regional la centra­lizare: două proiecte legislative ale universitarilor clujeni privind reforma învățământului superior românesc după 1918
Authors: Stan Ana-Maria
Published: May 2021

After the Great War and the union of Bessarabia, Bukovina, Transylvania, and the Banat with the Old Kingdom, the reform of higher education and, implicitly, its transformation into a unitary and efficient system required a lot of efforts. A significant number of initiatives and projects were discussed by the Romanian academic circles, politicians, and by the broader public before the first law for the organization of universities in Greater Romania was adopted and implemented, in April 1932. This article is a case study, which focuses on two proposals put forward in the 1920s by some prominent professors of the University of Cluj. My research tries to clarify and enrich our knowledge regarding the various stages that preceded and shaped the 1932 higher education law. It highlights the similarities and differences between these projects, looking, in particular, at their most relevant and modern elements. The article could equally provide points of comparison for future analysis regarding the reconstruction of the educational systems in other Central or Eastern European countries, in the first half of the 20th century.
The Humboldt Fellowships for Eastern Europe During the Cold War: Politics and Numbers
Authors: Nastasa-Matei Irina
Published: May 2021

The Alexander von Humboldt Foundation was re-established in the Federal Republic of Germany in 1953, with the aim of demonstrating that Germany continued to be a great cultural power and of marking its place on the international arena. It awarded very prestigious fellowships to researchers from abroad, based on the criteria of academic excellence and lack of quotas. Even if sporadically at the beginning, the Foundation’s relationship with the countries of Eastern Europe started to develop in the late 1960s, despite the opposite political systems of the two blocs. This happened in the context of the FRG’s East-centered foreign policy (Ostpolitik), and was also due to the opening of
socialist countries to the West. The relationship, however, was marked in many cases by tensions, as political interests, as opposed to the cultural or academic dimension, prevailed. The article tackles the situation of the Humboldt fellows from Eastern Europe during the Cold War, focusing, from a comparative perspective, on the quantitative aspect, as well as on the political dynamics which determined their presence in West Germany.

Published: May 2021

Guru adalah pembimbing bagi anak taman kanak-kanak. Proses tumbuh kembang anak sangat ditunjang oleh peran guru sebagai pembimbing. Agar guru dapat melaksanakan layanan bimbingan pada anak maka guru perlu menguasai berbagai karakteristik pembimbing.  Namun, akhir-akhir ini seringkali muncul fenomena di mana seorang guru TK menganiaya siswa nya.  Beberapa alasan yang mendasari terjadinya perilaku tersebut adalah keterpaksaan kondisi ekonomi yang mengharuskan seseorang untuk bekerja sebagai seorang guru TK padahal, dirinya tidak memiliki kompetensi di bidang tersebut.  Alasan lain adalah karena ketidakmampuan guru untuk mengelola emosi, lelah secara psikis dalam menghadapi anak-anak dll.  Bahkan beberapa kejadian guru yang menganiaya muridnya viral di media sosial

Berdasarkan pentingnya peran seorang guru maka dirasa perlu adanya pemberian suatu pelatihan ataupun penyuluhan kepada para guru TK/PAUD untuk bisa lebih memahami karakter seperti apa yang harus dibangun oleh seorang pendidik, dan juga agar lebih mampu memimpin dirinya sendiri.

Dari kegiatan yang telah dilakukan, diperoleh hasil bahwa sebanyak 70% guru-guru Mutiara Qur’ani yang telah diberikan pelatihan kepemimpinan diri mengaku merasa lebih mampu mengenal dirinya sendiri, mampu mengelola emosi yang dimiliki sehingga mereka merasa lebih nyaman dan santai dalam bekerja.

New Theory of Soil and Water Conservation Conservation
Authors: Guo Zhongsheng
Published: May 2021

Water and soil loss affects the carbon and nitrogen cycles of terrestrial ecosystems, forest vegetation ecosystem products and services, and ultimately the quality of life and sustainable development of the public. China has the most serious soil erosion in the world, notably on the Loess Plateau. After years of efforts, soil and water conservation in China has developed rapidly, the surface runoff and soil loss in soil and water loss areas have decreased rapidly, and people’s living standards have gradually improved. With these improved living standards, people have higher requirements for soil and water conservation. However, soil and water conservation lacks scientifi c theoretical guidance. In this paper, through comprehensive analysis of relevant literature, a new theory of soil and water conservation is proposed. The results shows that soil and water losses refer to the process of transferring soil and water resources from one place to another, and the consequences of these losses can be divided into positive and negative effects. Soil and water conservation is not only the use of some methods or measures to reduce soil erosion to soil allowable loss requirements, but also to make efficient use of soil and water resources. The construction standard of soil and water conservation measures must be based on the allowable amount of soil erosion and be applied using spatially optimal allocation, and the work of soil and water conservation should ensure regional ecological security and realize the sustainable development of soil and water conservation.
Clubs, Coase, and the Role of Government
Authors: Roumasset James
Published: May 2021

As Ronald Coase and others have shown, deducing the appropriate role of the government in the economy requires a comparative institutions approach. Trying to generalize from oversimplified specifications regarding transaction costs, according to whether exclusion is possible or not, is a futile exercise. An alternative to the Ostrom matrix is to distinguish private, club, and collective consumption goods according to their technical characteristics, specifically their degree of congestabiilty. The other box of the Ostrom matrix, “common pool” resources, can also be usefully analyzed from a club perspective. Spillover goods are spatial clubs. Lastly, a version of the Coase theorem is offered, which provides the foundation of comparative institutional analysis.
A socio-economic history of a village in Central Luzon: Thirty-six years of household survey, 1977-2013
Authors: Quimba Francis Mark , Estudillo Jonna
Published: May 2021

This study aims to give a detailed account of how household sources of livelihood, income, and poverty change under the pressure of four modernizing forces: (1) population pressure on closed land frontier; (2) implementation of land reform; (3) expansion of public infrastructures such as irrigation systems, roads, and schools; and (4) growing urban influences accelerated by improvements in transportation and telecommunication systems. This study was conducted in a village in Central Luzon where recurrent household surveys were done for 36 years from 1977 to 2013 encompassing the period of dramatic diffusion of modern rice technology. The major finding is that the interaction between the four modernizing forces and the diffusion of modern rice technology resulted in major economic and social changes that led to a rise in household income and prevented poverty from increasing. This study provides evidence contrary to the popular belief that the spread of modern agricultural technology and the encroachment of market activities into rural villages are harmful to the economic welfare of the rural Filipino people.

Lyme Borreliosis Associated with Sensorineural Hearing Loss: A Case Report
Authors: Albaini Obey , Abikanaan Georges , Sabri Alain
Published: May 2021

Background: Lyme borreliosis is a tick-borne infection caused by Borrelia species. It has a geographic distribution that makes it more frequent in certain regions like like North America and Europe. It manifests in a wide range of symptoms but is often under-investigated in patients presenting with sensorineural hearing loss (SNHL).  
Case Report: In this report, we describe a case presenting with SNHL as a manifestation of neuroborreliosis in a female adult patient suffering from Lyme disease, with multiple metachronous symptoms, including arthritis and seizures. Lyme borreliosis (LB) was clinically diagnosed and supported by positive serologic tests, along with Babesiosis. The patient was treated with intravenous (IV) ceftriaxone and azithromycin, in addition to oral atovaquone. Improvement after 4 weeks of IV ceftriaxone was noted in all aspects, including SNHL and arthritis.
Conclusion: LB is a possible, but rare, etiology of hearing impairment. It has been documented that if treatment is initiated early, improvement and even complete recovery are possible. Hence, in a patient presenting with SNHL and a high index of suspicion for LB, assessment for LB is warranted.
MULTI-OBJECTIVE SUSTAINABILITY OPTIMIZATION OF CCHP SYSTEMS CONSIDERING THE DISCRETENESS OF EQUIPMENT CAPABILITIES
Authors: Ren Xusheng , Ding Shimin , Dong Lichun , Qin Lixiao
Published: May 2021

The value of waste heat had led to an extensive study on Combined Cooling, Heating and Power (CCHP) system in recent decades, but the following three research gaps still need to be tackled to achieve a better economic and environmental performance. Firstly, the complete discreteness of equipment capabilities had not been considered. It means that multiple units with different capacities cannot be selected for a type of equipment. Then, the ambiguity and subjectivity existing in decision-makers/stakeholders’ judgments on the importance of objectives are usually ignored. Finally, an easily understood and comprehensive environmental indicator based on life cycle perspective for system optimization had not been established. Thus, the aim of this study is to establish a mathematical framework to help the stakeholders select the optimal configurations, capacities, and operation conditions of CCHP system while narrowing the above three research gaps to avoid the sub-optimal solutions. Subsequently, a hypothetical case was used to verify the validity of the proposed model, along with analysis of system performance. The results indicate that the CCHP system is superior to the conventional systems, and the proposed mathematical model in this paper can improve the performance of CCHP system in terms of economy, environment, and energy.

Published: May 2021

L’évolution de la politique française d’internationalisation de l’enseignement supérieur, in situ et à l’international, est significative de profondes transformations du marché mondial de l’enseignement supérieur. La concurrence entre États s’est exacerbée et a généré de nouveaux standards internationaux de certification et une financiarisation croissante des formations. L’espace mondial de l’enseignement supérieur s’est également considérablement reconfiguré : aux anciens pôles occidentaux de formation se sont ajoutés de nouveaux pôles dans les pays émergents. La volonté politique de gagner des parts de ce marché éducatif a enfin donné jour à l’externalisation d’institutions universitaires occidentales dans des pays du Sud. L’article met en évidence deux conséquences majeures de ces processus : d’une part, une transformation des périmètres du marché mondial d’enseignement supérieur, d’autre part, une reproduction accrue des élites.

A new technique for the incarcerated ileum reduction during laparoscopic obturator hernia repair
Authors: Zhang Yunliang , Xie Xiaojun , Chen Shubiao , Chen Dewang
Published: May 2021

Obturator hernia (OH) is a rare condition in all abdominal wall hernias, which usually presents with the symptoms of bowel obstruction caused by incarcerated intestinal segment, generally the ileum. We report a clinical case of an 81-year-old thin woman with 8-day history of nausea, vomiting, abdominal pain, and distension that aggravated for 1 day. A computed tomography scan showed an intestinal segment herniated into the obturator foramen in the left pelvic floor. A diagnosis of a left ileal, strangulated OH was made. A protective reduction management, air replacement method, was used to reduce the incarcerated ileum. Nonspecific symptoms of OH add difficulty in making diagnosis. Symptoms of bowel obstruction in patients with OH indicate incarceration. It is commonly seen in thin, elderly, multiparous women. Several ways for the reduction in patients with strangulated OH are described. Surgical approaches are the only choice for treatment. OH, a rare type in all hernias, is difficult to be diagnosed because of nonspecific symptoms. Air replacement method can reduce the incarcerated ileum successfully without unintentional injury.

Authors: Seker Duray , Seker Gaye Ebru , Bayar Bahattin , Ergul Zafer , Kulacoglu Hakan
Published: May 2021

INTRODUCTION:

Lichtenstein hernia repair is a clean surgical intervention and one of the most frequently applied operation worldwide. Despite guidelines, benefit of antibiotic prophylaxis in hernia surgery has been considered questionable and prophylaxis usage is not infrequent. Here, in this clinical randomized trial, we aimed to compare three different prophylaxis regimens to find out which one is more effective.

METHODS:

In this prospective study, patients were divided into three groups. First group (G1) received cefazoline, second group (G2) received topical gentamicin, and third group (G3) received combination of cefazoline and topical gentamicin. On 1st, 7th, and 30th postoperative days, surgical sites were examined for the signs of infection according to the definitions of Centers for Disease Control. Furthermore, effectiveness of infection prevention in patients with comorbid diseases was also analyzed.

RESULTS:

Totally 276 patients were analyzed. In G1 three, in G2 two, and in G3 0 infections were recorded. Total, infection rate was 1.8%. There was no any difference in infection rates between three groups (P = 0.285). Comorbidities did not rise infection rates under prophylaxis coverage (P > 0.05).

CONCLUSION:

All three methods are equally effective in surgical site infection, but combination method seems better with “0” ratio. Prophlaxy coverage also prevents surgical site infection even in the presence of risk (comorbidities).
A New Metabolite
Authors: Koh Yen-Chun , Liu Sheng-Yang , Wu Jia-Ching , Chou Ya-Chun , Nagabhushanam Kalyanam , Ho Chi-Tang , Pan Min-Hsiung
Published: May 2021

Background:

Curcumin and its metabolite, tetrahydrocurcumin (THC), have been widely studied due to their compelling capabilities in the prevention of various diseases. However, these compounds face some shortcomings, including the bioavailability of curcumin and comparatively weaker anti-inflammatory effects of THC. The amination of natural compounds in the hosts' colons has garnered attention because these aminated compounds retain and even increase their bioactivity relative to their original counterparts.

Materials and Methods:

The existence of THC-NH2 as a metabolite of THC in mice feces was analyzed by using LC-MS. Three-week DSS-induced colitis in mice experiment was designed to confirm the ameliorative effect of THC-NH2 on inflammatory bowel disease. The anti-inflammatory effect of THC-NH2 on LPS-treated murine macrophage RAW264.7 cell line was further clarified in vitro.

Results:

In this study, the metabolite 3-amino-3-deoxytetrahydrocurcumin (THC-NH2) was discovered in the feces of mice administered with THC. Compared to THC, THC-NH2 exhibits greater anti-inflammatory effects in terms of nitric oxide production. In a study of dextran sulfate sodium-induced colitis in which animal subjects were supplied with both THC and THC-NH2, each sample displayed encouraging but not compelling effects on inflammation reduction. In vitro research revealed that intervention using THC-NH2 could significantly reduce protein expression levels of nitric oxide synthase (iNOS) but cause the accumulation of cyclooxygenase-2 (COX-2). By using cycloheximide, THC-NH2 was found to retard the degradation of COX-2 by increasing its stability. However, mRNA levels of COX-2 and concentrations of prostaglandin E2 (PGE2) in spent medium indicated that COX-2 activity did not increase alongside its accumulated protein level, though no significant effects on the reduction of COX-2 activity were seen.

Conclusion:

As the current body of research is inadequate, in order to ensure that all things are considered, the efficacy and safety of THC-NH2 as a pharmaceutical drug require further investigation. Nevertheless, recent results showed that THC-NH2 can be used in multi-targeting anti-inflammation drugs to inhibit iNOS levels and reduce the side effects of COX-2 inhibitors by acting as a competitive inhibitor.
Dacarbazine and Bevacizumab Improved Paraneoplastic Doege–Potter Syndrome of Malignant Solitary Fibrous Tumor
Authors: Chen Ching-Tso , Lee Jen-Chieh , Huang Shih-Chiang , Chen Tom Wei-Wu
Published: May 2021

Solitary fibrous tumors (SFTs) are rare soft-tissue tumors that often occur in body cavities, especially the pleural space. A subset of SFTs is histologically malignant and tends to metastasize; rarely, they may induce paraneoplastic syndromes. Doege–Potter syndrome is paraneoplastic hypoglycemia induced by oversecretion of unprocessed insulin-growth factor-2. While localized SFTs are treated mainly by surgery, the standard therapy for metastatic SFTs is lacking. Here, we present a case with metastatic malignant SFT and Doege–Potter syndrome, which was treated initially by dacarbazine and bevacizumab with a period of good clinical response.
Multidisciplinary Management of Musculoskeletal Pain During Pregnancy
Authors: Ferreira Valeska Beatrice , Iuamoto Leandro Ryuchi , Hsing Wu Tu
Published: May 2021

Introduction:

Women may have higher prevalence of musculoskeletal chronic pain than men. Some studies suggest that biomechanical changes during pregnancy are related to elevated chronic pain prevalence.

Objectives:

The objective of this study is to conduct a review of studies involving strategies in multidisciplinary rehabilitation for musculoskeletal pain management during the pregnancy and the postpartum period.

Methodology:

The elaboration of the scientific question considered pregnant patients (population), rehabilitation with multidisciplinary team (intervention), without any comparatives, and pain management in any region of the body (outcome). The research was conducted in the databases: Medline (via PubMed) - http://www.pubmed.com and EMBASE - http://www.embase.com.

Results:

A total of 972 articles were found. Only two articles were related to rehabilitation with a multidisciplinary team for the management of pain in pregnant women. These articles were selected based on their relevance and data update.

Conclusion:

Although the literature has well established the cost-effectiveness of using multidisciplinary strategies for chronic pain control and intervention in its factors, there are no well-defined protocols for the application of these strategies in pregnant women, as shown by the scarcity of studies found on the subject in the bibliographic survey to perform this review. This reinforces the need for further studies with objective assessment parameters that analyze the effectiveness of multidisciplinary approach to musculoskeletal pain control and prevention of chronicity in pregnant women.

Attitude-Support Relationship in Gambling: A Modified Theory of Planned Behaviour
Authors: Thomson Albino Roshan , Mekoth Nandakumar
Published: May 2021

In this study, we modified the theory of planned behaviour and proposed that attitude towards gambling explains and predicts gambling support. We explored whether locals and tourists support or oppose the gambling industry and the factors that led to support or opposition. This information is vital, as policy decisions are often made by taking into consideration  public support. Using a structured questionnaire, we gathered data from 385 respondents from Goa, a popular tourist and gambling destination in India. Through structural equation modelling, we found that most of the variance (87%) in support of gambling  was explained by attitude. Perceived benefits and risks explained the significant variance (58%) in attitude towards gambling, as indicated in the theory of planned behaviour. The coefficients were significant except for the path from social risk to attitude, which was removed from the final model. The direct path from benefits and risk to support were not significant. In addition, the path from personal risk to attitude was moderated by the respondent’s gambling behaviour. Although gamblers had a more positive attitude with increasing personal risk, non-gamblers had a more negative attitude with increasing personal risk. This finding confirms the risk-seeking behaviour of gamblers. Résumé Cet article modifie la théorie du comportement planifié et avance que l’attitude à l’égard des jeux de hasard explique et prédit l’appui donné à ces jeux. L’étude vise à déterminer si les habitants et les touristes appuient l’industrie des jeux de hasard ou s’ils s’y opposent, et à cerner les facteurs menant à un appui ou à une opposition. Il s’agit d’une information de grande importance, car les décisions d’orientation prennent souvent en considération l’appui du public. Des données ont été recueillies au moyen d’un questionnaire structuré auprès de 385 répondants de Goa, en Inde, une destination touristique et de jeu très prisée. À l’aide d’une modélisation par équation structurelle, la recherche a révélé que la variance (87 %) dans l’appui aux jeux de hasard s’explique en majeure partie par l’attitude. Comme le suggère la théorie du comportement planifié, les avantages et les risques perçus expliquent la variance importante (58 %) dans l’attitude à l’égard des jeux de hasard. Les coefficients sont significatifs, à l’exception de la piste causale entre le risque social et l’attitude, qui a été retirée du modèle final. Les pistes directes allant des avantages et des risques vers l’appui n’étaient pas significatives. Il est apparu que les comportements de jeu des répondants avaient un effet modérateur sur la piste allant du risque personnel vers l’attitude. L’attitude des joueurs était de plus en plus positive à mesure qu’augmentait le risque personnel, tandis que celle des non-joueurs était de plus en plus négative. Ce résultat confirme l’existence d’un comportement de recherche du risque chez les joueurs.
Challenges in the Measurement of Gambling Product Risk: A Critical Review of the ASTERIG Assessment Tool
Authors: Delfabbro Paul , Parke Jonathan
Published: May 2021

Recognition of the role of structural characteristics and their potential association with gambling harm has led to the development of protocols to assess the risk of gambling products. Such tools rate products on a range of ‘risk criteria’ and assign classifications that might be used to inform product design or regulatory decision-making. One of published examples of these tools is ASTERIG which assigns ratings of lowest to highest to products based on 10 criteria that include, for example: event frequency, accessibility or scale of jackpot. In this paper, we provide a critical review of this protocol and identify five principal limitations that may limit its validity and reliability. These relate to the validity of some criteria as indicators of risk; definitional issues; scoring and calibration; problems arising from collinearity or duplication; and, the omission of important criteria such as cost of play. In this paper, we highlight the challenges associated with rating product risk using ASTERIG as an example. We argue that further refinement of risk assessment tools requires the development of more rigorous conceptual frameworks both in design and application as well greater validation of risk classifications against independent data relating to the links between products and gambling-related harm.RésuméLa reconnaissance du rôle des caractéristiques structurelles et de leur association potentielle avec les maux liés aux jeux de hasard a entraîné l’élaboration de protocoles visant à évaluer le risque des produits de jeu. De tels outils évaluent les produits sur une échelle de « critères de risque » et leur classement peut servir à orienter la conception de produits ou la prise de décisions réglementaires. L’un des exemples de ces outils est ASTERIG, qui attribue aux produits une cote, de la plus basse à la plus élevée, à l’aide de dix critères, notamment la fréquence de l’événement, l’accessibilité au gros lot ou la taille de ce dernier. Nous présentons dans cet article un examen critique de ce protocole et nous cernons cinq grandes limites pouvant restreindre sa validité et sa fiabilité. Ces limites concernent la validité de certains critères en tant qu’indicateurs de risque, des questions définitionnelles, le pointage et l’étalonnage, les problèmes issus de la colinéarité ou du double compte, et l’omission de critères importants comme le coût du jeu. Nous mettons en évidence dans cet article les enjeux liés à l’évaluation du risque d’un produit à l’aide d’ASTERIG par exemple. Nous soutenons que le peaufinage des outils d’évaluation du risque nécessite la mise sur pied d’un cadre conceptuel plus rigoureux, tant sur le plan de la conception que de l’application, ainsi qu’une plus grande validation des catégories de risque par rapport à des données indépendantes sur les liens entre les produits et les maux associés aux jeux de hasard.
