We introduce two new partial orders on the standard Young tableaux of a given partition shape, in analogy with the strong and weak Bruhat orders on permutations. Both posets are ranked by the major ...index statistic offset by a fixed shift. The existence of such ranked poset structures allows us to classify the realizable major index statistics on standard tableaux of arbitrary straight shape and certain skew shapes. By a theorem of Lusztig–Stanley, this classification can be interpreted as determining which irreducible representations of the symmetric group exist in which homogeneous components of the corresponding coinvariant algebra, strengthening a recent result of the third author for the modular major index. Our approach is to identify patterns in standard tableaux that allow one to mutate descent sets in a controlled manner. By work of Lusztig and Stembridge, the arguments extend to a classification of all nonzero fake degrees of coinvariant algebras for finite complex reflection groups in the infinite family of Shephard–Todd groups.
Students are increasingly relying on contract cheating (CC), a phenomenon in which a third party completes the assignment, quiz, or homework for students in exchange for a fee. Using an exploratory ...qualitative method and underpinned by critical theory and social responsibility theory, this study explored the perceptions of faculty members regarding CC in the United Arab Emirates’ (UAE’s) higher education institutions. In particular, this study addressed how faculty members perceive and deal with CC in contexts where policies towards the practice are absent from higher institution honour codes. Using thematic analysis, the results showed that CC arouses the indignation of faculty and staff to the violation of individual and religious rights. Also, they believe they have a sense of responsibility towards students and the community. The results also showed that faculty members’ hesitation in reporting CC incidents was due to their perceived lack of support from higher administration institutions and the lack of clear procedures in ethical manuals. This paper concludes with practical recommendations for faculty and staff, managers, department heads and decision makers to mitigate this phenomenon proactively.
In this study, we posit a new category of products provided by diploma mills, which we term Life Experience Degree Offerings (LEDOs). LEDOs uniquely capitalise on the misuse of the principle of ...Accreditation of Prior Learning (APL) by granting higher education qualifications based on a resume or CV alone. Through a comparative analysis with contract cheating websites, we highlight the key features and persuasive strategies employed by 10 diploma mill websites which provide LEDOs to attract and convince potential clients. We then use corpus linguistics methods by analysing a large corpus of text quantitatively to explore the keywords these websites use to describe their products using a pre-packaged corpus analysis tool (Sketch Engine). Our findings indicate that on providers’ websites, the LEDOs are framed as a tool to achieve greater socioeconomic opportunities, and the quality and appearance of the physical diploma and accompanying documents play a key role in the LEDOs’ value proposition, while references to the acquisition of knowledge and process of learning are absent. Furthermore, LEDOs are typified by the promise of accreditation and verification services, which are the two most common keywords used in the description of LEDOs on diploma mills’ websites. Future research directions are suggested, including examining this phenomenon in non-Western cultural contexts, understanding the users and operators of LEDO websites, and assessing the prevalence of fraudulent credentials obtained from these sites.
We compute all the spin fake degrees for the exceptional Weyl groups, which are by definition the graded multiplicities of the simple modules of a spin Weyl group in its spin coinvariant algebra. The ...spin fake degrees are all shown to be palindromic polynomials.
This paper critiques the multifarious ways whereby academic qualifications may be falsified in the international marketplace. The objectives are fourfold: (1) defining the main terms used such as ...fake degrees and diploma mills; (2) providing a brief history of fake degrees and identifying the factors that explain their recent development; (3) developing a theoretical framework to analyze fake degrees; and (4) exploring the costs and benefits of this activiry and its net impact on a given society. Degrees serve instrumental and ceremonial purposes. It is argued that degree holders may be considered as members of a club. They confer to their holders excludable but non-rival property rights such as abilities, signaling and status. The paper contends that holders of fake degrees can be considered as "free riders" on these property rights, especially the status tied to legitimate degrees.

We show how to derive new instances of the cyclic sieving phenomenon from old ones via elementary representation theory. Examples are given involving objects such as words, parking functions, finite ...fields, and graphs. PUBLICATION ABSTRACT
Despite the fact that fake degrees have been used since the creation of legitimate diplomas, the fake degrees business is reaching epidemic proportions, notably because of globalization, new ...information and communication technologies and ?diploma race?. We define the concept of fake degrees and distinguish different kinds of fakes. We also indicate the main functions of diplomas in the economic literature. We identify the supply and demand sides of the market of fake degrees and also consider other affected parties. We show that this growing business generates several negative spillovers that harm, among others, non traditional education institutions such as distance learning institutions and experience based learning. Moreover, we show that French law is well-equipped to deal with production, marketing and use of fake degrees. We also analyze some counter strategies that agents design and implement in order to prevent faking degrees from an efficiency and effectiveness viewpoint.
Bien que peu étudiés, le commerce et l’utilisation des faux diplômes constituent un phénomène en pleine expansion. Leur émergence remonte à un passé lointain, quasi concomitant à la création des ...vrais diplômes. Après avoir défini la notion de faux diplômes, nous mettons en évidence les différentes catégories de faux diplômes. Cette catégorisation permet de distinguer plusieurs logiques marchandes. Une attention particulière est accordée aux différentes parties prenantes, notamment aux producteurs, consommateurs et victimes des faux diplômes. Cette économie parallèle génère de nombreuses externalités négatives, susceptibles de nuire notamment aux institutions d’éducation non traditionnelles, comme la formation à distance ou la validation des acquis de l’expérience. De plus, nous montrons que le droit pénal français dispose de moyens de lutte conséquents en rapport avec les activités de production, de commercialisation et d’utilisation des faux diplômes. Les stratégies cherchant à contrecarrer le développement de ce phénomène sont également analysées à l’aune de leur efficacité et de leur efficience.
