Purpose: To investigate the effects of online reviews on consumer purchase intention considering the moderating role of product involvement and consumer expertise. Methodology: To reach our goal in this paper, we conduct a descriptive study in a deductive way. This is quantitative research in which the relationship between online reviews and consumer buying behavior will be tested. The research strategy of the study is an online survey. The sample size is 200 respondents considering confidence level 95% and confidence interval 7. Data editor IBM SPSS is used to performing the data analysis. Findings: High-low product involvement and high-low consumer expertise have an impact on the factor of online review (quality, quantity, and credibility) significantly and it affects the purchase intention of the consumer. The study created a conceptual model, which is adapted from the ELM model that considers expertise, involvement, perceived quality, quantity credibility of online consumer review and intent to purchase. This study found that the effect of review type (quality) on the intention of purchase was stronger for both experts and novice and both high-low involvement products. Depending on the level of involvement, the quantity of review on purchase intention increases but the quantity of review on the intention to purchase did not differ under both low involvement & high expertise. Again, individuals rely on source credibility when product involvement is low. But the credibility of the review did not differ on the purchase of intention under low involvement and low expertise situation. Research implications: This study applies the ELM model to measure the cognitive factor (review factor) and motivation factor (involvement and expertise) together. This study shows consumers with different levels of involvement and expertise prefer different levels of online review factors. The marketer could classify online review information into different category lines like the attribute-based review, benefit-based review, etc. and based on the analysis, the marketer can make a different plan for a different level of consumer (expert and involved consumer). Keywords: Quality, quantity, and credibility of review, Product involvement, consumer expertise, elaboration likelihood model (ELM Model).

L’expertise du risque biologique joue un rôle central dans l’élaboration et la mise en œuvre de la politique sanitaire et environnementale au niveau de l’Union européenne. Depuis la crise dite de la « vache folle », le législateur de l’Union a reconnu la nécessité d’encadrer davantage cette expertise. Toutefois, si le droit de l’Union s’intéresse au cadre scientifique de l’expertise du risque biologique, il traite de façon lacunaire la question de son cadre juridique. En effet, si les exigences d’indépendance, d’impartialité et de transparence sont affirmées à l’égard de l’expert, leur application manque de clarté et menace à terme la protection de la santé et de l’environnement des citoyens de l’Union. Pour remédier à ce problème, cette étude propose des critères ayant pour but l’établissement d’une réglementation au niveau de l’Union de l’expertise du risque biologique. Ces critères ont été établis après l’analyse du cadre juridique existant, des modèles d’expertise issus des législations de certains Etats membres et tiers à l’Union ainsi que de contributions doctrinales. / Biological risk expertise plays a central role in the development and implementation of health and environmental policy at EU level. Since the "mad cow" crisis, the Union's legislator has recognized the need to provide more guidance for this expertise. However, while EU law is concerned with the scientific framework of biological risk expertise, it does not address the issue of its legal framework in a comprehensive way. Indeed, while the requirements of independence, impartiality and transparency are affirmed with regard to the expert, their application lacks clarity and ultimately threatens the protection of the health and environment of EU citizens. To address this problem, this study proposes criteria for establishing EU-level regulation of biological risk expertise. These criteria were established after analysis of the existing legal framework, models of expertise from the legislation of certain Member States and third countries as well as doctrinal contributions.

The problems of judicial expertise in criminal proceedings Abstract Judicial Expertise is a substantial and irreplaceable part of criminal proceedings. It's legal regulation is required to fulfil high demands. Firstly, it must provide an effective platform for usage of expert evidence in criminal proceedings. Secondly, it ought to ensure that experts provide quality outcomes in compliance with lege artis. Thirdly, it should offer satisfying conditions for expert's activities. This thesis selects a few of the current issues originating from aforementioned requirements. It analyses their origin and evaluates how the Czech legal regulation solves them. At first, the thesis defines fundamental institutes which create a base for an expert's function in criminal proceedings. Subsequently, it offers an overview of statutory regulation of judicial expertise in criminal proceedings. It deals with both special regulation in criminal law and general regulation of Act No. 254/2019 Sb., on judicial experts, expert offices and expert institutes, together with relevant ordinances. Chapter three deals with legislative changes in the field of judicial experts effective from 1st January 2021. It focuses on new experts appointing, remuneration and supervision of experts' activities. It analyses and compares how these issues...

The rise of 'information disorder' that undermine Western political principles has become one of the key political concerns in current Europe and United States and led to searching for new solutions how to fight the spread of mis- and dis-information. While the nature of this danger is still subject to much debate, we can already observe a rise of new experts explaining the threat of information war and how to deal with it. This research looks at how this novel problematization of security affects the politics of security expertise. Or, who gains power in this 'battle for truth'? Building on sociological approaches in security studies, this thesis focuses on the Czech Republic as a country that has become very active in the fight against disinformation and analyses the network of actors recognized as providing security expertise on information warfare. Based on social network analysis, the research maps the structure of social relations among actors recognized as experts and points out the empowerment of think-tanks and journalists, who build their expertise by bringing together their social capital, bridging knowledge of Russian politics and the new media environment, and introducing new practices to make the society resilient towards information warfare.

Die zunehmende Bedeutung von Social Media im privaten und beruflichen Kontext ist mit der steigenden Notwendigkeit einer spezifischen Kompetenz für Social Media als Voraussetzung für die Bewältigung individueller beruflicher Alltagssituationen verbunden. In dem vorliegenden Beitrag wird das Konstrukt der Social-Media-Kompetenz beschrieben und mit dem Projekt „Social Media Communication“ eine Möglichkeit vorgestellt, wie die Entwicklung einer solchen Kompetenz unter gleichzeitiger Verwendung von Social-Media-Technologien als Lernmethode gefördert werden kann. Hergeleitet aus theoretischen und organisatorischen Anforderungen an ein entsprechendes Lernarrangement wird die Entwicklung und Erprobung eines prototypischen Blended-Learning-Arrangements zur Förderung einer hochschultyp- und fächerübergreifenden Social-Media-Kompetenz vorgestellt.

Second language (L2) learners of English must learn to produce English phonemes, words, and sentences. These L2 learners make many errors when learning English; they may change the place or manner of articulation, insert vowels, or delete consonants. Obstruent sounds, such as fricatives, affricates, and stops, can be especially difficult for L2 learners. This study analyzed native English speakers’ perception of the quality of obstruents produced by native Mandarin Chinese and Korean speakers. Target words containing obstruents had been produced in three different tasks: in a carrier phrase, in a paragraph, and in a spontaneous speech sample. Obstruents were produced in word-initial position and word-final position. Raters with differing levels of expertise listened to these words and rated the perceptual quality of the obstruents within the words. This study found that overall, English obstruent productions by native Mandarin and Korean L2 speakers learning English were rated most clear when produced in word-initial position in a carrier phrase or a paragraph. The lowest ratings given were of obstruents in word-final position in spontaneous speech. No significant differences were found for listener expertise level. Combined with future research, results from this study will help educate the field of second language instruction as to how the speech of Korean and Mandarin learners of English is perceived. It also provides additional information on the effect that listener expertise has on the judgment of L2 speech production.

L’observation du système nerveux, de son métabolisme et de certaines de ses structures est possible grâce à la neuroimagerie. Une littérature importante issue du « neurodroit » véhicule des imaginaires et des fantasmes relatifs aux possibilités judiciaires qu’offriraient ces technologies. Qu’il s’agisse de détection du mensonge, d’identification cérébrale des individus dangereux ou encore de prédiction de comportements déviants, la neuroimagerie, en l’état actuel des technologies, ne peut pourtant être sérieusement conçue comme pouvant faire l’objet de telles applications. L’utilisation de la neuroimagerie dans le cadre d’expertises est néanmoins une réalité, dans les tribunaux canadiens comme dans la loi française. Cette thèse souligne que les conceptions des technologies dont témoignent les deux systèmes juridiques étudiés s’avèrent lacunaires, ce qui engendre des risques. Elle évoque les conditions du recours à une normativité extra-juridique, la normalisation technique, qui pourrait s’élaborer dans ce contexte controversé, et esquisse les traits d’un dialogue amélioré entre les normativités juridique et technologique. / Neuroimaging allows the observation of the nervous system, of both its metabolism and some of its structures. An important literature in “neurolaw” conveys illusions and fantaisies about the judicial possibilities that imaging technologies would contain. Whether it is about lies detection, cerebral identifications of dangerous individuals through their neurobiology or predictions of criminal behaviors, neuroimaging, in the current state of technologies, can not be seriously conceived as being able to offer such applications. Judicial uses of neuroimaging through expertise are a reality nonetheless, in Canadian courts as in French law. This thesis emphasizes that the conceptions of imaging technologies integrated in the two legal systems studied are incomplete, which creates an important amount of risks. It discusses the conditions for the use of an extra-legal normativity, the international technical standardization, which could be elaborated in this particular and controversial context, and outlines several features of an increased dialogue between legal and technological norms

Political parties in the Czech Republic have a dominant position in decision-making and nomination of public representatives. At the same time they must deal with complex problems, such as pension reform. I suppose therefore that they need an expert opinions for building their decision-making. Therefore, I would like to figure out my research how to deal with this, how they are able to generate the requisite expertise and how that expertise is used in the final decision. I wonder how institutional arrangements of political parties affects the process of creating professional views on public policy, namely to focus on the reform of the Czech pension system. Where and how exactly are formed the expert views on the functioning of the pension system in different political parties? I would like to reveal the basic criteria that determine who is considered an expert, and how this person is related to the organization of political party. I also focus on mainstreaming expertise during the subsequent political decisions. The basic methods of research will document analysis, interviews and observations.

Cognitive studies reveal that less-than-expert clinicians are less able to recognize meaningful patterns of data in clinical narratives. Accordingly, psychiatric residents early in training fail to attend to information that is relevant to diagnosis and the assessment of dangerousness. This manuscript presents cognitively motivated methodology for the simulation of expert ability to organize relevant findings supporting intermediate diagnostic hypotheses. Latent Semantic Analysis is used to generate a semantic space from which meaningful associations between psychiatric terms are derived. Diagnostically meaningful clusters are modeled as geometric structures within this space and compared to elements of psychiatric narrative text using semantic distance measures. A learning algorithm is defined that alters components of these geometric structures in response to labeled training data. Extraction and classification of relevant text segments is evaluated against expert annotation, with system-rater agreement approximating rater-rater agreement. A range of biomedical informatics applications for these methods are suggested.

In the digitally mediated world that we live in, self-tracking and monitoring technologies have been observed to become part of the various realms of our social lives, shaping and even disturbing relations that we take part in. This thesis has sought to explore how tensions emerge between digital tracking technologies, players and other human members of an elite football team and, thus, to address how those tensions are dealt with. By applying the ethnographic research methodology and adopting the theoretical framework of Actor-Network Theory (ANT), the study has pursued to investigate how the technologies participate in the players’ everyday practices as well as how the players navigate between the expertise of different human and non-human sources in the team. The results indicate that the involvement of tracking technologies can increase the possibility of tensions to arise between different participants in a network such as the studied football team. To deal with these tensions, this thesis has contributed with a prototype of a system around a player monitoring technology. It suggests roles, relations, factors and actions in order to enhance the understanding among those who manage such a technology, helping them to acknowledge and overcome possible tensions in the social process of tracking a football team. This service blueprint is constructed through co-design workshops together with the player participants.
