We employ the support vector machine classifier, over different types of kernels, to investigate whether observable variables of individuals and their household information are able to describe their consumption decision of film at theaters in Brazil. Using a very big dataset of 340,000 individuals living in metropolitan areas of a whole large developing economy, we performed a Knowledge Discovery in Databases to classify the film consumers, which results in 80% instances correctly classified. To reduce the degrees of freedom for SVM (...) and to learn the more important determinants of film consumption, we apply the Linear Discriminant Analysis that allows us to identify the key determinants of this consumption. The main individual characteristics are age, education, income, and preferences for cultural goods. Regarding the main geographic characteristics, these are the timing of sample, population concentration, and supply of movie theaters. The results point to an ineffective policy for the sector at the time investigated. (shrink)

Background Studying global health problems requires international multidisciplinary teams. Such multidisciplinarity and multiculturalism create challenges in adhering to a set of ethical principles across different country contexts. Our group on health system responses to violence against women (VAW) included two universities in a European high-income country (HIC) and four universities in low-and middle-income countries (LMICs). This study aimed to investigate professional and policy perspectives on the types, causes of, and solutions to ethical challenges specific to the ethics approval stage of (...) the global research projects on health system responses to VAW. Methods We used the Network of Ethical Relationships model, framework method, and READ approach to analyse qualitative semi-structured interviews (n = 18) and policy documents (n = 27). In March-July 2021, we recruited a purposive sample of researchers and members of Research Ethics Committees (RECs) from the five partner countries. Interviewees signposted policies and guidelines on research ethics, including VAW. Results We developed three themes with eight subthemes summarising ethical challenges across three contextual factors. The global nature of the group contributed towards power and resource imbalance between HIC and LMICs and differing RECs’ rules. Location of the primary studies within health services highlighted differing rules between university RECs and health authorities. There were diverse conceptualisations of VAW and vulnerability of research participants between countries and limited methodological and topic expertise in some LMIC RECs. These factors threatened the timely delivery of studies and had a negative impact on researchers and their relationships with RECs and HIC funders. Most researchers felt frustrated and demotivated by the bureaucratised, uncoordinated, and lengthy approval process. Participants suggested redistributing power and resources between HICs and LMICs, involving LMIC representatives in developing funding agendas, better coordination between RECs and health authorities and capacity strengthening on ethics in VAW research. Conclusions The process of ethics approval for global research on health system responses to VAW should be more coordinated across partners, with equal power distribution between HICs and LMICs, researchers and RECs. While some of these objectives can be achieved through education for RECs and researchers, the power imbalance and differing rules should be addressed at the institutional, national, and international levels. Three of the authors were also research participants, which had potential to introduce bias into the findings. However, rigorous reflexivity practices mitigated against this. This insider perspective was also a strength, as it allowed us to access and contribute to more nuanced understandings to enhance the credibility of the findings. It also helped to mitigate against unequal power dynamics. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Denying Divinity: Apophasis in the Patristic Christian and Soto Zen Buddhist TraditionsJoseph S. O'LearyDenying Divinity: Apophasis in the Patristic Christian and Soto Zen Buddhist Traditions. By J. P. Williams. Oxford: Oxford University Press, 2000. Pp. 249. $65.00.Janet Williams studied patristic theology at Oxford and Soto Zen in Tokyo, in the circle of Nishijima Zenji. In Denying Divinity: Apophasis in the Patristic Christian and Soto Zen Buddhist Traditions, (...) her excellent account of negation and silence in Pseudo-Dionysius and Maximus the Confessor (pp. 64-126) and in Dogen (pp. 126-179) is preceded by surveys of apophasis in earlier Christianity and Buddhism and followed by an eloquent defense of the importance of the twofold apophatic tradition for contemporary theology (pp. 180-228).The initial surveys show a sure-footed scholarly competence that may owe something to the author's experience as an investment banker. Her writing often exhibits a concentrated justesse, as in the two paragraphs on Origen (pp. 26-27). The temptation to forced comparisons between the two traditions is avoided until the concluding chapter, apart from a few unconvincing touches such as this remark: "How similar all this sounds to the 'unsupported thought' and the 'absence of thought-coverings' in the Prajñaparamita literature!"—in reference to Gregory of Nyssa on Abraham's faith, which was "unmixed and pure of any concept" (p. 29). Similarly, to speak of Plotinus' "recoil from—or transcendence of—ontological views" (p. 18) is inappropriately Nāgārjunian; Plotinus held firm, dogmatic views and entertained a host of speculative ones. (Incidentally, it is probably wrong to identify the experience recounted in Enneads IV.8—the relatively frequent ascent of the soul to contemplate the intelligible realm—with the union with the One, evoked in Porphyry, Life of Plotinus 23, a much rarer event [p. 21].)Gregory of Nyssa is nudged in the direction of Buddhism when Williams talks of "the inchoate undermining of the realist ontology he inherited from Plato and Aristotle" (pp. 32-33) and suggests that "the hesitation between ontology and 'disontology,' if it were a little more developed, would become the kind of recoil from [End Page 370] ontological views which we see as characteristic of apophasis" (p. 36). As a very kataphatic theologian in dogmatic debate, Gregory has no aversion to views; his apophasis applies only to certain views of the divine, especially heretical ones that he sees as hubristic. In Mādhyamaka Buddhism, one transcends "views" about anything, but in the Greek Fathers it is only views concerning God that are problematized. The Buddhist transcending of views is oriented to a nondual experience of everyday reality, but in the Fathers it concerns only the divine simplicity, infinity, and transcendence and the mysteries of the eternal generation of the Son and the Incarnation. It is untrue that "there is no explicit apophasis in Gregory" (p. 35): there is plenty of it in Contra Eunomium II, albeit of a simple kind. Nonetheless, Gregory's ontology remains realistic even at the level of divine being. One might query the view expressed by Rowan Williams that, for Gregory, the divine essence becomes "an abstraction and, in a sense, a fantasy" (p. 34).Dionysius is presented as a mobile and open-ended thinker who has been underestimated. He "negates both affirmation and negation, but by offering no third alternative, in a sense affirms them too as the only usable theological resources" (p. 121). Maximus accords with this, although attaining "a finer balance of incarnational christo-centrism over Neoplatonism" (p. 124). The claim that Dionysius "is at pains to distance himself from the Neoplatonist tradition of making transcendence prior or superior to immanence" (p. 216) is overstated, and it misses the degree to which Proclus had already seen the cosmos as pervaded by divine eros (as pointed out long ago by Anders Nygren).The emphasis on a nonduality of transcendence and immanence brings Dionysius into a rapprochement with more of the this-worldly Zen vision. Similarly, the stress on a "shocking activity of emptiness" (p. 141) in Dogen hints at a parallel with the divine ekstasis in Dionysius. But the latter is merely a variant of the Neoplatonic...
