This article examines fifty case files of cybercriminals that the Economic and Financial Crimes Commission (EFCC) convicted for online romance fraud. It profiles offenders and explores the value of the Space Transition Theory in understanding digital crimes. Through documentary analysis, the study identifies key patterns in victim demographics, fraudsters’ operational strategies, and offenders’ socioeconomic backgrounds. Findings reveal a high concentration of U.S. victims (56%) and a preference among offenders for Apple’s iPhone (58%). Most offenders presented themselves as Caucasian American males (...) (46%) or military personnel (12%), with some adopting Caucasian European male identities (10%). Victim demographics show a pronounced gender disparity: 70% of offenders primarily targeted female victims, 14% targeted male victims, 10% reached both genders, and 6% did not specify the victims’ gender. The analysis also indicates that most offenders were university students (74%), with Facebook (46%) identified as the primary platform for these fraudulent activities. The study emphasizes the need for prevention strategies that genuinely consider the socioeconomic and political conditions that may make online fraud an appealing career option. (shrink)

This study used an emic approach to examine the dynamics of online romance fraud, focusing on the migration of offenders from Nigeria to Ghana. We collected data through qualitative methods, such as semi-structured interviews and focus group discussions. Ghanaian police officers and Nigerian law enforcement officers were consulted for their perspectives. Thematic analysis revealed key findings, including the migration patterns of Nigerian offenders to Ghana and the institutionalisation of scamming enterprises. These findings shed light on the transnational and structural factors (...) driving online romance fraud in West Africa, highlighting both its global reach and the local mechanisms sustaining these criminal networks. This research contributes to a deeper understanding of regional and international cybercrime dynamics, offering valuable insights to inform policy and law enforcement strategies. (shrink)

This paper examines the polemical nature of anti-racist education and discourse in America today. On one side of this issue are those who think of the efforts toward inclusion, diversity, and the pursuit of social justice in academia as serving positive ends. On the other side are those who oppose and vilify such efforts as evidence of the destructive ethos of liberal education. This has led to a situation where universities and schools across the country have seen professors and teachers, (...) including philosophers, experience backlash for speaking seriously and courageously about confronting the problem of racism in society. One recent example of this anomaly is the kind of faux outrage or moral panic that drives the hysteria against Critical Race Theory, an inquiry that examines the intersection of race and law in the United States, as well as unearthing the reality of structural racism in America, often disguised in the mainstream liberal approaches to racial justice. This faux moral panic has been used by legislatures across the country, as the raison d’être, to pass bans and enforce policies or rules that restricts how professors (including philosophers), and teachers can talk about race, systemic racism, structural oppression, or the problem of racial injustice in the classroom. In this paper, I explore how this polemical situation creates significant challenges and unique possibilities for the discourse of philosophy, especially for those who are interested in becoming antiracist philosophers, in the context of such legal rules and restrictions. This is not for the faint of heart. (shrink)

There are established ethical principles to protect human participants in biomedical research from undue exploitation by researchers. However, in the “Tuskegee Study” in the US, these principles were grossly violated. The task of this paper is to critically examine the ethical implications of that study on future practices in biomedical research, and to suggest ways of ensuring that such practices comply with appropriate ethical values.

The Retributivist approach to punishment attempts to address the challenges posed by utilitarian conception that punitive actions should strictly be associated with a costeffective means to certain independently identifiable goods at the expense of justice. Justice proffers how the guilty deserve to be punished and no moral consideration relevant to punishment outweighs an offender’s criminal desert. However, this just desert provokes difficulty in discerning proportionality between the moral gravity of each offence and the specific penalties attached. This consequently degenerates to (...) another form of ‘lex talionis’ (revenge) in punitive justice. (shrink)

Within the notion of punishment in the Yoruba culture, the physical and non-physical aspects of human existence are reconciled to arrive at a justifiable punitive action. The metaphysical presuppositions in Yoruba punitive system reflect a coherent interconnection among social structure, law and belief system for the harmonious human well-being of the individual and the community. Furthermore, the judicious imposition of punitive measures on the offender establishes the significance of attributing responsibility for every human action without antagonism and animosity. Nevertheless, the (...) offender, within the tradition, is restitutively reconciled with himself, the victim and the community at large. The social order based on these principles creates and modifies the contemporary understanding of penology and penal practice. (shrink)

In current discussions on African epistemology, the issue of justification of beliefs has mainly been considered from an externalist perspective, such that justification is described as achievable merely through the means of empirical verification and social context of discourse. However, this results in a knowledge-gap since both internalist and externalist perspectives are needed to arrive at a holistic notion of epistemic justification. Consequently, the objective of this article is to fill this gap by employing the methods of conceptual and critical (...) analysis to attempt an internalist interpretation of epistemic justification in the quest for a more balanced view of African epistemology.

A challenge human existence is confronted in contemporary society is the justification of a coherent social order. Most of these justifications have been grounded, over time, on natural approach to the neglect of the African ontological practice. This natural reference fails to account for the ontological practice premised on African belief system which reconciles the natural and spiritual aspects of human existence. The study adopts the analytic approach in philosophy which evolves a clarification of the ontological concept within the African (...) context.The African ontological practice hinges on Dukor’s perspective which provides for a coherent interconnection among social structure, law and belief system towards the certitude and trust making for harmonious human well-being.Social order is enhanced by this African ontological practice and should, therefore, be incorporated into the public sphere.

This paper discusses citizenship in Finnish religious education in relation to human security. It traces the characteristics of human security that connect citizenship, religion, and education in Finnish policy documents. The article focuses on basic education. Its data were analyzed employing qualitative content analysis. The findings indicate that citizenship in Finnish RE entails personal security concerns dealing with psychological and human rights issues. These are found to be essentially human security as conceptualized by the United Nations. However, Finnish policy documents (...) sparingly utilize human security in explicit terms. Finland rather emphasizes the practical applications of human security. Incorporation of explicit global citizen and human rights issues into RE in the new Finnish curriculum seems to project critical global citizenship. This is found to promote human security. Following Finland’s bid for practical application of human security, we recommend that human security be explicitly integrated into the Finnish RE curriculum. (shrink)

O Projeto de Pesquisa realizado através do NIQ – Núcleo de Ilustrações e Quadrinhos, pelo Centro de Estudos em Design da Imagem da UEMG – UNIVERSIDADE DO ESTADO DE MINAS GERAIS, tem a pretensão de incentivar alunos da Escola Municipal Secretário Humberto de Almeida em Belo Horizonte-Minas Gerais-Brasil a comunicar a cultura brasileira, em especial às raízes culturais da Capital mineira, através de levantamento e análise de material em quadrinhos na Internet.

In recent years, the work of organizations in the area of digitization has intensified significantly. This trend is also evident in the field of recruitment where job application tracking systems (ATS) have been developed to allow job advertisements to be published online. However, recent studies have shown that recruiting in most organizations is not inclusive, being subject to human biases and prejudices. Most discrimination activities appear early but subtly in the hiring process, for instance, exclusive phrasing in job advertisement discourages (...) qualified applicants from minority groups from applying. The existing works are limited to analyzing, categorizing and highlighting the occurrence of bias in the recruitment process. In this paper, we go beyond this and develop machine learning models for identifying and classifying biased and discriminatory language in job descriptions. We develop and evaluate a machine learning system for identifying five major categories of biased and discriminatory language in job advertisements, i.e., masculine-coded, feminine-coded, exclusive, LGBTQ-coded, demographic and racial language. We utilized the combination of linguistic features with recent state-of-the-art word embeddings representations as input features for various machine learning classifiers. Our results show that the machine learning classifiers were able to identify all the five categories of biased and discriminatory language with a decent accuracy. The Random Forest classifier with FastText word embeddings achieved the best performance with tenfolds cross-validation. Our system directly addresses the bias in the attraction phase of hiring by identifying and classifying biased and discriminatory language and thus encouraging recruiters to write more inclusive job advertisements.

We consider the informal concept of "computability" or "effective calculability" and two of the formalisms commonly used to define it, "(Turing) computability" and "(general) recursiveness". We consider their origin, exact technical definition, concepts, history, general English meanings, how they became fixed in their present roles, how they were first and are now used, their impact on nonspecialists, how their use will affect the future content of the subject of computability theory, and its connection to other related areas. After a careful (...) historical and conceptual analysis of computability and recursion we make several recommendations in section §7 about preserving the intensional differences between the concepts of "computability" and "recursion." Specifically we recommend that: the term "recursive" should no longer carry the additional meaning of "computable" or "decidable;" functions defined using Turing machines, register machines, or their variants should be called "computable" rather than "recursive;" we should distinguish the intensional difference between Church's Thesis and Turing's Thesis, and use the latter particularly in dealing with mechanistic questions; the name of the subject should be "Computability Theory" or simply Computability rather than "Recursive Function Theory.".

Meu objetivo neste artigo é defender que podem ser atribuídos sentidos distintos para os termos “vontade” e “volição” na filosofia de Hume. Ao contrário das interpretações tradicionais, sustento que Hume não identifica vontade e volição. Inicialmente, apresento argumentos de Hobbes e Locke contra a concepção escolástica sobre a produção de ações voluntárias e defendo que Hume associa-se a esses dois filósofos. A seguir, apresento os argumentos da interpretação tradicional que identifica vontade e volição na filosofia humeana e também algumas objeções (...) feitas a tais argumentos. Por fim, em oposição à interpretação tradicional, defendo que Hume acredita que a vontade pode ser compreendida como a faculdade pela qual produzimos ações voluntárias e que volições são paixões motivacionais em exercício. As paixões motivacionais que produzem ações são volições, que é a percepção pela qual produzimos ações voluntárias. (shrink)

It is shown that for every nonzero r.e. degree c there is a linear ordering of degree c which is not isomorphic to any recursive linear ordering. It follows that there is a linear ordering of low degree which is not isomorphic to any recursive linear ordering. It is shown further that there is a linear ordering L such that L is not isomorphic to any recursive linear ordering, and L together with its ‘infinitely far apart’ relation is of low (...) degree. Finally, an analogue of the recursion theorem for recursive linear orderings is refuted. (shrink)

Corporate social responsibility has become a much-discussed subject in the business world. The Internet has become one of the main tools for CSR information disclosure, allowing companies to publicise more information less expensively and faster than ever before. As a result, corporations are increasingly concerned with communicating ethically and responsibly to the diversity of stakeholders through the web. This paper addresses the main question as whether CSR information disclosure on corporate websites is influenced by country of origin and/or industry sector. (...) Analysing the websites of 127 corporations from emerging countries, such as Brazil, Chile, China, India, Indonesia, Mexico, Thailand and South Africa, it becomes evident that both country of origin and industry sector have a significant influence over CSR information disclosure on the web .

O que Foucault entende por jornalismo e como ele se relaciona com a filosofia? Para responder à questão, escrutinamos declarações do autor francês acerca do assunto, especialmente sobre dois personagens: Nietzsche “o primeiro filósofo-jornalista” e Kant “o responsável por introduzir o hoje na filosofia”. Detalhando nuances, pretendemos mostrar em que o pensamento de Foucault se avizinha de um jornalismo radical, e em que deste ele se diferencia.

Post in 1944 began studying properties of a computably enumerable set A such as simple, h-simple, and hh-simple, with the intent of finding a property guaranteeing incompleteness of A . From the observations of Post and Myhill , attention focused by the 1950s on properties definable in the inclusion ordering of c.e. subsets of ω, namely E = . In the 1950s and 1960s Tennenbaum, Martin, Yates, Sacks, Lachlan, Shoenfield and others produced a number of elegant results relating ∄-definable properties (...) of A , like maximal, hh-simple, atomless, to the information content of A . Harrington and Soare gave an answer to Post's program for definable properties by producing an ∄-definable property Q which guarantees that A is incomplete and noncomputable, but developed a new Δ 3 0 -automorphism method to prove certain other properties are not ∄-definable. In this paper we introduce new ∄-definable properties relating the ∄-structure of A to deg, which answer some open questions. In contrast to Q we exhibit here an ∄-definable property T which allows such a rapid flow of elements into A that A must be complete even though A may possess many other properties such as being promptly simple. We also present a related property NL which has a slower flow but fast enough to guarantee that A is not low, even though A may possess virtually all other related lowness properties and A may simultaneously be promptly simple.

We begin with the history of the discovery of computability in the 1930’s, the roles of Gödel, Church, and Turing, and the formalisms of recursive functions and Turing automatic machines . To whom did Gödel credit the definition of a computable function? We present Turing’s notion [1939, §4] of an oracle machine and Post’s development of it in [1944, §11], [1948], and finally Kleene-Post [1954] into its present form. A number of topics arose from Turing functionals including continuous functionals on (...) Cantor space and online computations. Almost all the results in theoretical computability use relative reducibility and o-machines rather than a-machines and most computing processes in the real world are potentially online or interactive. Therefore, we argue that Turing o-machines, relative computability, and online computing are the most important concepts in the subject, more so than Turing a-machines and standard computable functions since they are special cases of the former and are presented first only for pedagogical clarity to beginning students. At the end in §10–§13 we consider three displacements in computability theory, and the historical reasons they occurred. Several brief conclusions are drawn in §14. (shrink)

O presente artigo tem como objetivo apresentar as críticas de Martin Heidegger e de Gilbert Simondon à concepção corrente da técnica, referida por Heidegger como a “concepção instrumental e antropológica da técnica”. Trata-se de mostrar que as críticas desses pensadores, por mais diferentes que possam ser seus universos conceituais, seus objetivos e seus métodos, são ambas realizadas a partir de um processo de interpretação desconstrutiva dos conceitos de “instrumentalidade”, “alienação” e “hilemorfismo”, num conjunto crítico que a cada vez relaciona diretamente (...) crítica da técnica à crítica da filosofia. Nesse sentido, as análises são apresentadas a partir dos respectivos horizontes de reflexão filosófica de cada autor: no caso de Heidegger, o projeto de elaboração da ontologia fundamental e, posteriormente, o pensamento da história do ser e, no caso de Simondon, a questão da individuação.

I argue that grammatical thomism helps to clarify certain problems in philosophical theology by focusing attention on the parameters of coherent God-talk. By drawing on figures like David Burrell, Brian Davies, Kathryn Tanner, and Denys Turner, I show that the first rule of theological grammar is to avoid talking about God as if God were some sort of thing existing alongside the world. In fact, Aquinas concedes that we cannot really know what God is at all. Nevertheless, Wittgenstein’s later emphasis (...) on meaning as use helps us to see why we can still talk intelligibly about God by focusing on the use of the word more than its referent. I connect this with the work of Stephen Mulhall and Cora Diamond on the nature of riddles, and suggest that this genre is one way of illuminating the peculiar grammar of certain Christian doctrines: in particular, the doctrine of the incarnation and of creation out of nothing. Finally, I look outside Christian contexts to the Hindu tradition of Advaita Vedānta, and argue that the language and imageries of non-dualism can provoke us into reconsidering the essence of Christian grammar and alert us to some of the therapeutic possibilities of grammatical thomism.

Este artigo objetiva apresentar as interpretações de Arthur Danto e Gianni Vattimo sobre a questão “fim da arte”, introduzida por Hegel em seus Cursos de Estética. Segundo Danto há, no presente, uma transformação radical nas condições de produção das artes. As definições da arte não podem mais se fundamentar na inspeção direta das obras, exigindo uma mudança na forma de se refletir sobre a arte. O “vazio” das definições de arte no momento em que “tudo é permitido” traz a questão (...) do “fim da arte”. Ora, para Danto, o “fim da arte” não significa o fim das produções artísticas na contemporaneidade, mas o fim das narrativas mestras. É um meio de se mostrar que as narrativas que definiram a arte tradicional chegaram a um fim e que a arte contemporânea não mais permite uma representação por narrativas. Vattimo, discorre, em consonância com Danto, acerca das transformações da arte e das insuficiências da Estética tradicional na contemporaneidade. Contudo, Vattimo destaca a incapacidade da Estética em compreender os mass media e suas possibilidades positivas. Para Vattimo, a reprodutibilidade técnica e a massificação são inconciliáveis com as definições tradicionais da Estética. Assim, a reflexão vattimiana busca apreender o sentido do estético na sociedade dos mass media, remetendo-se à questão do “fim da arte” em um sentido “pervertido” como generalização da esfera dos meios de comunicação.

Epistemologists have recently started appealing to the moral philosophy literature on interpersonal trust in order to help explain the epistemology of testimony. We argue that epistemologists who have given trust a significant role in their accounts of the epistemology of testimony have appealed to very different conceptions of the nature of trust, which have inevitably influenced the shape of their epistemological theorizing. Some have employed accounts of the nature of interpersonal trust according to which trust is a practical phenomenon subject (...) to the will and to practical reasoning. Such accounts face the task of showing how the practical phenomenon that is interpersonal trust has epistemic implications for testimonial belief. Other theorists have employed accounts of the nature of interpersonal trust according to which trust is at least partly a cognitive phenomenon, itself subject to epistemic norms. Such accounts do not face the task of showing how practical rationality has implications for theoretical reason. Instead, they face the rather different tasks of showing how it is that cognitive trusting bears genuinely interpersonal features, and of how theoretical rationality can share features with practical rationality.

As interrogações podem ser definidas como a disjunção de todas as suas possíveis respostas. Assim definidas, elas nada dizem e são equivalentes às leis lógicas. Basicamente, as interrogações, conforme a variável questionada, podem ser enunciativas, individuais ou predicativas. Fundamentalmente as interrogações têm duas possíveis respostas ; mas as individuais e as predicativas, por uma dessas respostas ser uma particularização, podem ser consideradas interrogações de múltiplas possíveis respostas.

A current issue in psycholinguistic research is whether the language difficulties exhibited by children with developmental language disorder [DLD, previously labeled specific language impairment ] are due to deficits in their abilities to pick up patterns in the sensory environment, an ability known as statistical learning, and the extent to which explicit learning mechanisms can be used to compensate for those deficits. Studies designed to test the compensatory role of explicit learning mechanisms in children with DLD are, however, scarce, and (...) the few conducted so far have led to inconsistent results. This work aimed to provide new insights into the role that explicit learning mechanisms might play on implicit learning deficits in children with DLD by resorting to a new approach. This approach involved not only the collection of event-related potentials, while preschool children with DLD [relative to typical language developmental controls] were exposed to a continuous auditory stream made of the repetition of three-syllable nonsense words but, importantly, the collection of ERPs when the same children performed analogous versions of the same auditory SL task first under incidental and afterward under intentional conditions. In each of these tasks, the level of predictability of the three-syllable nonsense words embedded in the speech streams was also manipulated to mimic natural languages closely. At the end of both tasks’ exposure phase, children performed a two-alternative forced-choice task from which behavioral evidence of SL was obtained. Results from the 2-AFC tasks failed to show reliable signs of SL in both groups of children. The ERPs data showed, however, significant modulations in the N100 and N400 components, taken as neural signatures of word segmentation in the brain, even though a detailed analysis of the neural responses revealed that only children from the TLD group seem to have taken advantage of the previous knowledge to enhance SL functioning. These results suggest that children with DLD showed deficits both in implicit and explicit learning mechanisms, casting doubts on the efficiency of the interventions relying on explicit instructions to help children with DLD to overcome their language difficulties.

O presente artigo examina como a obra historiográfica _Revoluções Cisplatinas_, de 1915, do político, diplomata e historiador Alfredo Augusto Varella, representa tanto disputa política como uma forma de escrita da história sobre a Farroupilha. A partir da hipótese de que na Primeira República, no Rio Grande do Sul, houve uma hegemonia social e política do PRR quer se investigar como a obra de Varella articulou-se com o seu contexto. Portanto, o objetivo é analisar como foi construída a narrativa sobre a (...) Farroupilha no contexto de disputas em torno do borgismo. Para atingir tal objetivo, usa-se o conceito de operação historiográfica de Michel de Certeau, isto é, como a partir de uma análise do lugar social, da prática científica e da escrita do texto pode-se perceber as transformações na escrita da história sobre a Farroupilha. Por fim, percebe-se que a obra analisada foi um objeto tanto de luta política como de virada interpretativa na escrita da Farroupilha. (shrink)

The present study uses EEG time-frequency representations with a Flanker task to investigate if and how individual differences in bilingual language experience modulate neurocognitive outcomes in two bilingual group types: late bilinguals and early bilinguals. TFRs were computed for both incongruent and congruent trials. The difference between the two was then compared between the HSs and the L2 learners, modeled as a function of individual differences with bilingual experience within each group separately and probed for its potential symmetry between brain (...) and behavioral data. We found no differences at the behavioral and neural levels for the between-groups comparisons. However, oscillatory dynamics of inhibition and cognitive control were found to be modulated by individual differences in bilingual language experience, albeit distinctly within each bilingual group. While the results indicate adaptations toward differential brain recruitment in line with bilingual language experience variation overall, this does not manifest uniformly. Rather, earlier versus later onset to bilingualism—the bilingual type—seems to constitute an independent qualifier to how individual differences play out. (shrink)

Let M be a smooth, compact manifold of dimension n ≥ 5 and sectional curvature | K | ≤ 1. Let Met (M) = Riem(M)/Diff(M) be the space of Riemannian metrics on M modulo isometries. Nabutovsky and Weinberger studied the connected components of sublevel sets (and local minima) for certain functions on Met (M) such as the diameter. They showed that for every Turing machine T e , e ∈ ω, there is a sequence (uniformly effective in e) of homology (...) n-spheres {P k e } k ∈ ω which are also hypersurfaces, such that P k e is diffeomorphic to the standard n-sphere S n (denoted P k e ≈ diff S n ) iff T e halts on input k, and in this case the connected sum N k e =M ♯ P k e ≈ diff M , so N k e ∈ Met(M), and N k e is associated with a local minimum of the diameter function on Met(M) whose depth is roughly equal to the settling time σ e (k) of T e on inputs y i } ∈ ω of c.e. sets so that for all i the settling time of the associated Turing machine for A i dominates that for A i + 1 , even when the latter is composed with an arbitrary computable function. From this, Nabutovsky and Weinberger showed that the basins exhibit a "fractal" like behavior with extremely big basins, and very much smaller basins coming off them, and so on. This reveals what Nabutovsky and Weinberger describe in their paper on fractals as "the astonishing richness of the space of Riemannian metrics on a smooth manifold, up to reparametrization." From the point of view of logic and computability, the Nabutovsky-Weinberger results are especially interesting because: (1) they use c.e. sets to prove structural complexity of the geometry and topology, not merely undecidability results as in the word problem for groups, Hilbert's Tenth Problem, or most other applications; (2) they use nontrivial information about c.e. sets, the Soare sequence {A i } i ∈ ω above, not merely G öodel's c.e. noncomputable set K of the 1930's; and (3) without using computability theory there is no known proof that local minima exist even for simple manifolds like the torus T 5 (see §).

This article presents Hanna Arendt’s theory about political judgement, i.e., the expresion of the discursive reason in the political sphere. A certain lack of faith in the public exercise of discursive reason, motivated by her negative experience of totalitarism, leads Arendt to adopt a skeptical and Kantian conception of judgement, which only leaves place for a human action and freedom shorn of rationality in the political arena.
