Based on an account of the Brighton Photo-Biennial Memory of Fire: The War of Images and Images of War, curated by Julian Stallabrass in late 2008, this essay considers the photographic coverage of the recent imperialist interventions in the Middle East. Taking its cue from Stallabrass's event, it reflects on the decline of documentary and photojournalism since the Vietnam War and the current attenuated politics of the media. It argues that the problem of the sublime (...) extends beyond the current genre of 'aftermath'-photography and asks what might constitute a more cognitively adequate politics of the image. (shrink)

The following essay is part of a body of work titled Signal to Noise: sound and fury in (post)apartheid South Africa. These are a collection of creative non-fiction essays set against the backdrop of my involvement with a small, independent mobile recording studio based in Johannesburg between 1983 and 1997. The metaphor of a drowning signal, pushing through and making itself heard above the noise, resonates throughout the collection. The complexities of the political versus artistic nature of what we were (...) involved with provide a setting for an anecdotal approach to what is part history, part biography, part memoir and part theoretical sonic exploration. The following essay falls into this approach and is constructed from memories enhanced by diaries, scrap-books, shards of notes, lyrics, photos and conversations. These have been employed in reconstructing a narrative arc that covers the recording of the first album made by the band Sankomota, who were banned from entry into South Africa and were based in Maseru, mostly playing to audiences at one of the leading hotels. Sankomota, then called Uhuru, experienced extraordinary, almost metaphysical, peaks and troughs throughout their nearly thirty-year existence hence the hauntological device in the title. The record was also the first made in our fledgling mobile studio using newly affordable equipment that kickstarted many such do-it-yourself projects worldwide. This was the first in a steady stream of technologies that would eventually break the hegemony of mainstream record companies. In apartheid South Africa, this was hugely significant, as being able to sideline the censorship of state-owned media enterprises meant immense freedom in the kind of projects one came to consider. Savage incidents of force and brutality were still common then, and our small venture has to be seen in the context of broader unrest and suffering. Frank Leepa was an uncompromising survivor. His words and melodies still move and inspire a younger generation. (shrink)

Early followers of Jesus and later rabbinical Jews, two divergent branches of Judaism emerging respectively from the Second Temple and Post-Second Temple eras, both drew upon the cultural memory of Sinai to establish their identity. This article examines how the author of Acts used the Sinai imagery of theophanic fire in the Pentecost narrative of Acts 2 to reinforce a continu­ation of Judaism and offer an inclusive expansion of it to gentile believers. Then it looks at how later (...) rabbinic sources used Sinai images of fire and multiple languages to reinforce the authority of the Torah and their exclusive identity within the Sinai relationship.

Our programmatic article on Homo heuristicus (Gigerenzer & Brighton, 2009) included a methodological section specifying three minimum criteria for testing heuristics: competitive tests, individual-level tests, and tests of adaptive selection of heuristics. Using Richter and Späth’s (2006) study on the recognition heuristic, we illustrated how violations of these criteria can lead to unsupported conclusions. In their comment, Hilbig and Richter conduct a reanalysis, but again without competitive testing. They neither test nor specify the compensatory model of inference they argue (...) for. Instead, they test whether participants use the recognition heuristic in an unrealistic 100% (or 96%) of cases, report that only some people exhibit this level of consistency, and conclude that most people would follow a compensatory strategy. We know of no model of judgment that predicts 96% correctly. The curious methodological practice of adopting an unrealistic measure of success to argue against a competing model, and to interpret such a finding as a triumph for a preferred but unspecified model, can only hinder progress. Marewski, Gaissmaier, Schooler, Goldstein, and Gigerenzer (2010), in contrast, specified five compensatory models, compared them with the recognition heuristic, and found that the recognition heuristic predicted inferences most accurately.

The system GLS, which is a modal sequent calculus system for the provability logic GL, was introduced by G. Sambin and S. Valentini in Journal of Philosophical Logic, 11, 311–342,, and in 12, 471–476,, the second author presented a syntactic cut-elimination proof for GLS. In this paper, we will use regress trees in order to present a simpler and more intuitive syntactic cut derivability proof for GLS1, which is a variant of GLS without the cut rule.

One way of dealing with the proliferation of conjectures that accompany the diverse study of the evolution of language is to develop precise and testable models which reveal otherwise latent implications. We suggest how verbal theories of the role of individual development in language evolution can benefit from formal modeling, and vice versa.

Heuristics are efficient cognitive processes that ignore information. In contrast to the widely held view that less processing reduces accuracy, the study of heuristics shows that less information, computation, and time can in fact improve accuracy. We review the major progress made so far: the discovery of less-is-more effects; the study of the ecological rationality of heuristics, which examines in which environments a given strategy succeeds or fails, and why; an advancement from vague labels to computational models of heuristics; the (...) development of a systematic theory of heuristics that identifies their building blocks and the evolved capacities they exploit, and views the cognitive system as relying on an “adaptive toolbox;” and the development of an empirical methodology that accounts for individual differences, conducts competitive tests, and has provided evidence for people’s adaptive use of heuristics. Homo heuristicus has a biased mind and ignores part of the available information, yet a biased mind can handle uncertainty more efficiently and robustly than an unbiased mind relying on more resource-intensive and general-purpose processing strategies.

While theories of rationality and decision making typically adopt either a single-powertool perspective or a bag-of-tricks mentality, the research program of ecological rationality bridges these with a theoretically-driven account of when different heuristic decision mechanisms will work well. Here we described two ways to study how heuristics match their ecological setting: The bottom-up approach starts with psychologically plausible building blocks that are combined to create simple heuristics that fit specific environments. The top-down approach starts from the statistical problem facing the (...) organism and a set of principles, such as the bias– variance tradeoff, that can explain when and why heuristics work in uncertain environments, and then shows how effective heuristics can be built by biasing and simplifying more complex models. We conclude with challenges these approaches face in developing a psychologically realistic perspective on human rationality. (shrink)

Online social networks have rapidly become a prominent and widely used service, offering a wealth of personal and sensitive information with significant security and privacy implications. Hence, OSNs are also an important—and popular—subject for research. To perform research based on real-life evidence, however, researchers may need to access OSN data, such as texts and files uploaded by users and connections among users. This raises significant ethical problems. Currently, there are no clear ethical guidelines, and researchers may end up performing ethically (...) questionable research, sometimes even when more ethical research alternatives exist. For example, several studies have employed “fake identities” to collect data from OSNs, but fake identities may be used for attacks and are considered a security issue. Is it legitimate to use fake identities for studying OSNs or for collecting OSN data for research? We present a taxonomy of the ethical challenges facing researchers of OSNs and compare different approaches. We demonstrate how ethical considerations have been taken into account in previous studies that used fake identities. In addition, several possible approaches are offered to reduce or avoid ethical misconducts. We hope this work will stimulate the development and use of ethical practices and methods in the research of online social networks. (shrink)

What is it for philosophy to make progress? While various putative forms of philosophical progress have been explored in some depth, this overarching question is rarely addressed explicitly, perhaps because it has been assumed to be intractable or unlikely to have a single, unified answer. In this paper, we aim to show that the question is tractable, that it does admit of a single, unified answer, and that one such answer is plausible. This answer is, roughly, that philosophical progress consists (...) in putting people in a position to increase their understanding, where 'increased understanding' is a matter of better representing the network of dependence relations between phenomena. After identifying four desiderata for an account of philosophical progress, we argue that our account meets the desiderata in a particularly satisfying way. Among other things, the account explains how various other achievements, such as philosophical arguments, counterexamples, and distinctions, may contribute to progress. Finally, we consider the implications of our account for the pressing and contentious question of how much progress has been made in philosophy. (shrink)

ABSTRACTWe investigated the impact of emotions on learning vocabulary in an unfamiliar language to better understand affective influences in foreign language acquisition. Seventy native English speakers learned new vocabulary in either a negative or a neutral emotional state. Participants also completed two sets of working memory tasks to examine the potential mediating role of working memory. Results revealed that participants exposed to negative stimuli exhibited difficulty in retrieving and correctly pairing English words with Indonesian words, as reflected in (...) a lower performance on the prompted recall tests and the free recall measure. Emotional induction did not change working memory scores from pre to post manipulation. This suggests working memory could not explain the reduced vocabulary learning in the negative group. We argue that negative mood can adversely affect language learning by suppressing aspects of native-language processing and impeding form-meaning mapping with second language words. (shrink)

This massive, expensive tome comprises all the proceedings of the 1970 biennial meeting of the Philosophy of Science Association. Beyond the selection of the papers to be presented at the meeting, there has been no winnowing of the good from the bad. Further, there is no indexing. Thus, the technical philosopher of science, to whose interest the contributed papers in this anthology will appeal, faces the prospect of doing these jobs himself. The symposium papers, which account for a relatively (...) small fraction of this volume, will interest readers of this journal the most. These papers investigate three topics: theoretical entities in statistical explanation; capacities and natures; history of science and its rational reconstruction. (shrink)

This study uses the Locke and Okali gender analysis framework to explore gender relations surrounding grain storage management and marketing in Binga District of Zimbabwe. The study was conducted during one grain storage season and involved multiple visits to selected households, which were used as case studies. The main question that the study sought to address was: “What bargaining goes on between men and women in the area of stored grain management and marketing?” Data were collected from four households, fitting (...) into the following categories: simple monogamous, complex monogamous (two scenarios), and polygamous. Participatory rural appraisal tools and techniques were extensively used and formed the backdrop of all the data collection. The study established that much bargaining and strategizing occurs within the household in order for women to exercise control over the use of stored grain. The bargaining process was found to be a complex one of give-and-take without an immediately recognizable winner. There is evidence that women use this bargaining power to exert influence on their relative position in the household in terms of independent income generation and management, seniority, and overall household food security policies. While bargaining between and within gender remains shrouded in subtleness, individuals in a household consciously use their skills to manipulate the situation to their best advantage. This article is expected to initiate broader debate in the area of gender roles and bargaining in grain post-harvest management, an area often kept private by smallholder farmers in sub-Saharan Africa.

In lieu of an abstract, here is a brief excerpt of the content:Soldiers of the Invisible Front: How Ukrainian Therapists Are Fighting for the Mental Health of the Nation Under FireIrina Deyneka and Eva RegelIrina DeynekaWhen the Russian army attacked my country, I became a volunteer for a hotline offering psychological support to those in crisis; refugees, those who were under the shelling, those who were hiding in bomb shelters, and who were directly in the zone of fighting. People were (...) lost and disoriented by constant bombing, by the fact that their country was under attack. Once, I had a woman who lived in Mariupol on one of these calls. I was living then in another city, Odessa, but was experiencing the same horrors of war that my client was—the shelling, uncertainty, and despair. We were processing my client’s feelings of grief and anxiety when I heard the sirens on her end. I offered to stop our session so she could seek shelter. She told me she would not have time to find shelter and wanted to continue our meeting. And so, we continued... But soon, Odessa’s sirens broke the silence, and it was my turn to decide what to do; should I continue our session or try to find a bomb shelter for myself? I decided to stay because I thought that was the right thing to do morally, professionally, and personally.I eventually left Odessa, but only after a bomb destroyed a house next to mine, and I saw a family, my neighbors, perish in the destruction. I am now a member of one of Slovakia’s Non-Governmental Organizations (NGOs) and work in a mobile brigade providing medical and psychological support to refugees. I can remember every one of my clients. Children, adults... I can remember their stories, their traumas, their memories of the horrors of war and devastation. Sometimes I meet with them only once, and they move on to another refugee center or are on their way to a Western part of Ukraine, trying to escape the war. And frequently, I do not know how many sessions I will be able to have with clients. Sometimes it is only one time, and sometimes we can meet for many months. Initially, I thought, What can I do in one therapy session? Now, I know that I can do a lot. I can provide people who survived the most inhuman conditions and witnessed death and destruction around them with a space and time to talk through and process their experiences. I am their support, and they lean on me as they try to make sense of what has happened to them and their country. I always tell my clients that my goal as a psychotherapist is to help them withstand, survive, and hold on while still being able to continue to function in a country at war. All I can do is treat each of the therapy sessions as our last one and try to provide as many strategies and skills as possible to cope with anxiety and depression, to be able to function, and to live in the present.Every session is about installing hope, moving slowly forward, and away from traumatic events. One of my clients, a 14-year-old boy, was diagnosed with a neurological condition, involuntary facial muscle spasm, or tics. He was barely talking when I first saw him, and I decided to use art therapy as a trauma-processing tool during one of the therapy sessions. He was drawing an explosion, fire, and destruction of his neighbor’s house. He blacked out the horrors of his experience to preserve his strength. Yet, he began slowly remembering his experiences, re-creating the story of his trauma, and making memories. I was fortunate to work with [End Page E4] him for many months, carefully and thoughtfully helping him re-create the sorry of his trauma, helping to become its witness. Ultimately, it was great to see that he could control his memories and his emotional stress; he felt empowered and in control.Eva RegelThis is the story of Irina Deyneka, one of many Ukrainian psychotherapists working in Ukraine, providing mental health support to a nation ravaged by...

Previous studies provided evidence for a connection between language processing and language change. We add to these studies with an exploration of the influence of lexical-distributional properties of words in orthographic space, semantic space, and the mapping between orthographic and semantic space on the probability of lexical extinction. Through a binomial linear regression analysis, we investigated the probability of lexical extinction by the first decade of the twenty-first century (2000s) for words that existed in the first decade of the nineteenth-century (...) (1800s) in eight data sets for five languages: English, French, German, Italian, and Spanish. The binomial linear regression analysis revealed that words that are more similar in form to other words are less likely to disappear from a language. By contrast, words that are more similar in meaning to other words are more likely to become extinct. In addition, a more consistent mapping between form and meaning protects a word from lexical extinction. A nonlinear time-to-event analysis furthermore revealed that the position of a word in orthographic and semantic space continues to influence the probability of it disappearing from a language for at least 200 years. Effects of the lexical-distributional properties of words under investigation here have been reported in the language processing literature as well. The results reported here, therefore, fit well with a usage-based approach to language change, which holds that language change is at least to some extent connected to cognitive mechanisms in the human brain.

On their journeys toward senior athletic status, junior endurance athletes are faced with a multitude of stressors. How athletes react to stressors plays a vital part in effective adaptation to the demanding, ever-changing athletic environment. Sleep, the most valued recovery strategy available to athletes, has the potential to influence and balance athletic stress, and enable optimal functioning. However, sleep is sensitive to disturbances by stress, which is described by the concept of sleep reactivity. Among athletes, poor sleep quality is frequently (...) reported, but our understanding of the associations between stress and sleep in junior athletes is currently incomplete. The present study therefore investigated the themes of stress and sleep, and the associations between these variables with the use of in-depth semi-structured interviews in six junior endurance athletes. Data was analyzed qualitatively based on the Grounded Theory. The qualitative material was supplemented with quantitative data on subjective sleep quality, sleep reactivity, and mental strain. The main results showed that stress could be differentiated into relevant stressors and reactions to stress. Sleep could be differentiated into sleep benefits and sleep quality. All athletes identified relevant stressors, and all athletes were aware of the benefits of sleep for athletic functioning. However, athletes formed two distinctive categories based on the interactions between stress and sleep: three exhibited facilitative reactions to stress and good sleep quality, as well as low sleep reactivity, and low mental strain. The remaining participants exhibited maladaptive reactions to stress and poor sleep quality, as well as high sleep reactivity and high mental strain. Conceptualizing sleep quality based on the evaluation of stressors, reactions to stress, degree of mental strain, and the propensity to stress-related sleep disturbance may offer a plausible explanation for why the occurrence of stressors leads to poor sleep quality in some athletes, but not others.

Abstract:This study analyses how the migrant experience is reflected in the geography of Hugo Hamilton's work of fiction entitled Hand in the Fire (2010). The novel is told from the point of view of Vid, a Serbian immigrant who is trying to settle in Ireland. The young carpenter endeavours to fit in Irish society through his friendship with a young Dublin lawyer, Kevin Concannon, who tells him that a true friend would put his “hand in the fire” for (...) you. Through the portrayal of these displaced characters, Hamilton explores his favourite themes of memory and belonging. This article focuses on the places depicted in the novel, from the Serbia that Vid has left in his past to the modern-day Dublin and the west coast of Ireland, in order to analyse how the settings of the narrative reflect the characters’ state of mind. Using Deleuze and Guattari's concepts of de/re-territorialization and of striated/smooth spaces, the examination of the geographies of the novel allows for a better understanding of the issues at stake for the characters. The liminal, deterritorialized figure of the immigrant represented by Vid is echoed by the smooth islands of the novel. In an archipelagic country where the coastline stands for the visual border, it is no wonder that the transnational protagonist is drawn to the Irish shores. On the edge of two cultures, Vid, who lives in Dún Laoghaire, south of Dublin, is gradually moving west to the striated landscape of Connemara, where he investigates on Kevin's aunt who drowned and was washed ashore the Aran Islands.

When pandemics hit communities, women are bound to suffer as most of the responsibilities of ensuring food security lie on them. This article assesses the impact of the COVID-19 pandemic on the role that church-going women play in food provision. The qualitative study used interviews and focus group discussions to examine the toll of the pandemic-induced restrictions, especially with regard to their disruption of activities that ensure the provision of food for the family. They sought to identify how an environment (...) as restrictive as the one that was imposed during the COVID-19 pandemic affects those largely responsible for food provision in urban Marondera – the women, in this case. The focus was extended to factor in how disasters and pandemics affect women and detract from their normative food procurement and provision roles in marginal societies and how these effects can be mitigated to allow women to carry on with their roles even in restrictive environments. This research was motivated by the recent COVID-19-imposed regulations that restricted the movement of people, restrictions that have only recently been relaxed and (in some cases) removed. We also sought to establish how gender roles are played out, together with whether they are exacerbated by pandemics, and in what ways these pandemics result in higher workloads on women. By utilising the Africana womanist theory, the study analysed women roles in food provision and food security in their societies within the restrictive environments of the pandemics.Contribution: This study concluded that there are gender inequalities that are exacerbated by these pandemics that result in higher workloads for women. It foregrounded how existing gender inequalities were exacerbated by the pandemic, resulting in higher workloads on women. It therefore recommended that women should form empowerment groups to help focus attention on food provision to mitigate challenges women face in this role. Finally, we averred that there ought to be consultation and participation of women on issues to do with pandemics to allow for their full and productive participation in critical roles of providing food.
