Public reason and multi-layered justice

ABSTRACTThis paper aims to outline a multi-layered conception of justice that is appropriate to the circumstances of justice in the European Union. Adopting the Rawlsian concept of public reason, it submits that duties of justice can only be imposed to the extent that the actors involved command a shared set of reasons by which these can be justified. The paper’s argument follows Rawls in using public reason to justify a qualitative distinction between the demands that derive from the domestic and the international domain of justice. It criticises Rawls, however, for misjudging the radical implications of this position in a world that has become much more internationalised than he recognised it to be.

Acoustic analysis of the production of English monophthongs in Serbian EFL speakers at tertiary level

In learning and mastering a foreign language, adequate acquisition of a vowel system is regarded as particularly important, both for the speech intelligibility and successful communication. However, it is an undeniable fact that 'foreign accent' often remains present in foreign language speakers, regardless of their level of knowledge, primarily due to the interference and transfer of phonetic/phonological characteristics of the mother tongue. This paper examines phonological competencies of ESL students at tertiary level in the field of English vowel system. Students' ability to accurately and adequately recognize and produce qualitative and quantitative distinctions of relevant elements of the English phonological system through the oppositions of monophthongs [ɪ] - [i:], [e] - [æ], [ʌ] - [ɑː], [ɒ] - [ɔː], [ʊ] - [u:] is examined through an acoustic analysis of speech. The experiment included ten male participants, i.e. five freshmen and five seniors. The acoustic analysis attempted to explain how the period of two years of intensive English Language classes influenced the development of phonetic/phonological competencies in the field of monophthongs in the production of final-year students. The results are rather similar in both groups, with only a few exceptions. The period of two years of intensive learning of English as a foreign language did not provide noticeable results in the acquisition of vowels, but proved that the phonological competences of both groups are at the same level.

Effectively Maintained Inequality in Educational Transitions in the Republic of Ireland

While it is well established that the structure and organization of the education system affects youth transitions, less attention has been paid to the study of qualitative distinctions at the same level of education over time in the Irish context. Using data from the School Leavers’ Survey over the period 1980-2006, this paper considers the hypothesis of effectively maintained inequality in the case of the Republic of Ireland. The data capture young people’s transitions during three distinct and remarkable macro-economic fluctuations, and makes a particularly interesting test case for EMI. Over the cohorts under investigation, Ireland had changed from a recessionary economic climate and prolonged economic stagnation for much of the 1980s to a booming economy by the middle of the mid-2000s and one of the most dynamic economies in the world during the “Celtic Tiger” period. The patterns of social-class inequality over a 30-year paper reported in this article suggest that qualitative differences at the same level of inequality represent a persistent barrier to greater equality in the Irish context. Specifically, we find three notable patterns to support the hypothesis of EMI with regard to tracking decisions taken in the transition from lower secondary to upper secondary, subject-level differentiation in the upper secondary mathematics curriculum, and access to university higher education.

Educational Inequality in Apartheid South Africa

In this article, I explore the utility of effectively maintained inequality theory in examining educational inequality in South Africa at the end of the apartheid era. As an obviously unequal country, South Africa provides an excellent opportunity to test the claim that even with large quantitative differences in achievement, qualitative differences will matter. Using data from the early 1990s, I find that there were extensive quantitative differences in secondary school transitions across respondents in different racial categories. The minority White population was consistently able to achieve both more and better education. At the same time, though, qualitative distinctions mattered. For the majority of the population, particularly Africans, the quality of education attained varied across parental background. These outcomes are important not only for examining the veracity of effectively maintained inequality, both in terms of racial and class differences but also because they illustrate how educational differences have served to perpetuate inequality over time in a society that no longer allows for the explicit denial of opportunity by race.

Gold, Licht und das Potenzial des Mosaiks

Abstract The article focuses on the complex interaction between gold and light in the very specific medium of mosaic in Late Antiquity and Byzantium. Studying the metaphoric qualities of light/gold and its qualitative distinctions in early Christian and Byzantine sources leads us to an understanding of the complex function of gold or golden tesserae in script and images. As gold is understood as light, mosaic seems to be a more or less perfect medium as it is not stable, but dependent on the changing light. The gold ground is transformed in every moment by light. Mosaic can thus be understood as the medium with the greatest capacity to bridge – virtually – the gap between the visible and the invisible divine light.

Detection and characterization of volatile organic compounds from burned human and animal remains in fire debris

Debris collected from various test sites where mammalian remains (human and porcine) had been burned in a variety of full-scale fire scenarios was evaluated for the presence of volatile residues that could be characteristic of those remains. Levels of volatiles were measured using the method commonly used for fire debris analysis: gas chromatography–mass spectrometry. Homologous n-aldehydes (from n-pentanal to n-nonanal) proved to be a significant indicator of the presence of burned animal tissue as they were observed in nearly all of the samples. Such aldehydes are created by the combustion of animal fats. One aldehyde, n-hexanal, appeared more frequently than the other aldehydes, n-pentanal, n-heptanal, n-octanal, and n-nonanal. Ethanol was detected in two-thirds of the samples, while acetone appeared in about three-fourths of the samples, but both were detected at much lower concentrations than n-hexanal. These appear to have been combustion products of the substrates on which each body burned, rather than originating from the combustion of the body. There appeared to be no qualitative distinction between volatile products produced from burned porcine carcasses and those from human cadavers. Since a homologous series of C5–C9n-aldehydes is not produced as a dominant species by the pyrolysis or combustion of any normally encountered substrate (carpet, bedding, wood products or upholstery), their detection by normal fire debris methods appears to be a valid indicator of the presence of burned animal remains. These data will also provide guidance to fire debris analysts as to the nature of volatiles associated with the combustion of human bodies in real-world fires.

Determinants of Employee Innovative Behavior: Do Foreign and Domestic Companies in Russia Differ?

This paper investigates employees’ individual innovative behavior. Three main stages of innovative process – new ideas generation, their promotion and implementation – are examined. 623 Russian employees of domestic and foreign companies operating in Russia were surveyed. The results show high significance of individual determinants (status and self-assessment of professional competence), favorable organizational environment (managerial incentives) and types of decision-making for all three stages of innovative process. The authors’ main proposition that foreign companies demonstrate higher level of individual innovative activity was not confirmed but qualitative distinctions at all three stages of innovative process were revealed.

Facebook dethroned: Revealing the more likely social media destinations for college students' depictions of underage drinking

Studies examining representations of college drinking on social media have almost exclusively focused on Facebook. However, recent research suggests college students may be more influenced by peers' alcohol-related posts on Instagram and Snapchat, two image-based platforms popular among this demographic. One potential explanation for this differential influence is that qualitative distinctions in the types of alcohol-related content posted by students on these three platforms may exist. Informed by undergraduate focus groups, this study examined the hypothesis that, of the three platforms, students tend to use Instagram most often for photos glamourizing drinking and Snapchat for incriminating photos of alcohol misuse and negative consequences. Undergraduate research assistants aided investigators in developing hypothetical vignettes and photographic examples of posts both glamorizing and depicting negative consequences associated with college drinking. In an online survey, vignette and photo stimuli were followed by counterbalanced paired comparisons that presented each possible pair of social media platforms. Undergraduates (N=196) selected the platform from each pair on which they would be more likely to see each post. Generalized Bradley-Terry models examined the probabilities of platform selections. As predicted, Instagram was seen as the most probable destination (and Facebook least probable) for photos depicting alcohol use as attractive and glamorous. Conversely, Snapchat was selected as the most probable destination (and Facebook least probable) for items depicting negative consequences associated with heavy drinking. Results suggest researchers aiming to mitigate the potential influences associated with college students' glamorous and consequential alcohol-related photos posted social media posts should shift their focus from Facebook to Instagram and Snapchat.

‘Lines of Light’: Poetic Variations in Wordsworth, Byron, and Shelley

Recognising the importance of Wordsworth's sense of nascent light (elegised in his ‘Ode: Intimations of Immortality’), the essay traces how influential this idea was on later Romantic poetic treatments of light. Wordsworth's qualitative distinction between the ‘fountain light of all our day’ and the ‘light of common day’ reveals his alertness to the revelatory and blinding effects of light and establishes the terms of Byron's and Shelley's imaginative engagement with the transformative aspects of light in their depiction of Italian cityscapes and coastal scenes. This transformative quality of light, for Byron and Shelley, is inextricable from those utopian aspirations to recapture future edenic states, which are configured in terms that consign such future idylls to the irrecoverable past. Finally, Shelley's The Triumph of Life is read as avowing an apocalyptic, rather than transformative, light whose ‘severe excess’ is still reimagined in terms familiar to the reader of Wordsworth's ‘Ode’.

Probing boundaries between cultures and disciplines

Academia may be one of the world’s most globalized industries, but the humanities and social sciences are not immune to parochialism at various levels. In this interview with Media Asia editor Cherian George, Krishna Sen reflects on an academic career spent transcending national and disciplinary boundaries. Born in India, she made her mark as a leading scholar of Indonesian media and a senior administrator in Australian academe. Sen explains what drew her to study a country she had never visited, and the parallels she found with her own homeland. She shares the advice she gives to junior scholars when charting a course between disciplinary depth and breadth. And she wonders if the breaking of walls has gone too far, flattening qualitative distinctions that are required for sensible moral and esthetic judgment.

Experimental abrasion of water submerged bone: The influence of bombardment by different sediment classes on microabrasion rate

Data presented here demonstrates the utility of quantitative analysis of sediment-induced microabrasion on bone's surface. Fresh sheep (Ovis aries) bone, acting as a human analogue, was bombarded by mobile sediments from silt, sand and gravel classes (ranging 20μm–3.35mm) in a series of flume-based experiments. Controlled bombardment produced unique abrasion patterns on bone which were recordable using scanning electron microscopy. Imaging abrasion at both ×100 and ×1000 magnifications allowed quantitative and qualitative distinction to be made concerning the sediment class that the bone was abraded by; bombardment by gravel classes caused abrasion to advance through cyclical cracking, whereas smoothing of bone's surface occurred more frequently in sand and silt classes. A stepwise multi-linear regression model identified changes in sediment grain size (p<0.001), duration of exposure to abrasion (p<0.001), sphericity of the abrasive (p=0.002), and T value (abrasive force) (p=0.013) respectively, as the strongest rate limiting factors controlling microabrasion propagation. The methodology presented herein demonstrates analytical value by allowing diagnostic modifications to bone's surface to be correlated with specific taphonomic processes. Data developed from flume-based experimentation was applied in four separate case studies; abrasion data recorded on bones recovered from different aquatic contexts, was linked to hydrological and marine seabed sediment data to demonstrate how documented microabrasion can reflect the different sedimentary contexts bone has passed through. In light of these results we suggest that a quantitative approach to analysing abrasion on bone retrieved from water has potential to allow remains' submersion times and transport pathways to be established with a higher degree of resolution than is currently possible. The development of improved methodologies for the interpretation of submerged human bone is vital due to the increasing risks posed by flooding and coastal erosion to archaeological sites.

Enhancing Signal Output and Avoiding BOD/Toxicity Combined Shock Interference by Operating a Microbial Fuel Cell Sensor with an Optimized Background Concentration of Organic Matter.

In the monitoring of pollutants in an aquatic environment, it is important to preserve water quality safety. Among the available analysis methods, the microbial fuel cell (MFC) sensor has recently been used as a sustainable and on-line electrochemical microbial biosensor for biochemical oxygen demand (BOD) and toxicity, respectively. However, the effect of the background organic matter concentration on toxicity monitoring when using an MFC sensor is not clear and there is no effective strategy available to avoid the signal interference by the combined shock of BOD and toxicity. Thus, the signal interference by the combined shock of BOD and toxicity was systematically studied in this experiment. The background organic matter concentration was optimized in this study and it should be fixed at a high level of oversaturation for maximizing the signal output when the current change (ΔI) is selected to correlate with the concentration of a toxic agent. When the inhibition ratio (IR) is selected, on the other hand, it should be fixed as low as possible near the detection limit for maximizing the signal output. At least two MFC sensors operated with high and low organic matter concentrations and a response chart generated from pre-experiment data were both required to make qualitative distinctions of the four types of combined shock caused by a sudden change in BOD and toxicity.

Abstract and Effector-Selective Decision Signals Exhibit Qualitatively Distinct Dynamics before Delayed Perceptual Reports.

Electrophysiological research has isolated neural signatures of decision formation in a variety of brain regions. Studies in rodents and monkeys have focused primarily on effector-selective signals that translate the emerging decision into a specific motor plan, but, more recently, research on the human brain has identified an abstract signature of evidence accumulation that does not appear to play any direct role in action preparation. The functional dissociations between these distinct signal types have only begun to be characterized, and their dynamics during decisions with deferred actions with or without foreknowledge of stimulus-effector mapping, a commonly studied task scenario in single-unit and functional imaging investigations, have not been established. Here we traced the dynamics of distinct abstract and effector-selective decision signals in the form of the broad-band centro-parietal positivity (CPP) and limb-selective β-band (8-16 and 18-30 Hz) EEG activity, respectively, during delayed-reported motion direction decisions with and without foreknowledge of direction-response mapping. With foreknowledge, the CPP and β-band signals exhibited a similar gradual build-up following evidence onset, but whereas choice-predictive β-band activity persisted up until the delayed response, the CPP dropped toward baseline after peaking. Without foreknowledge, the CPP exhibited identical dynamics, whereas choice-selective β-band activity was eliminated. These findings highlight qualitative functional distinctions between effector-selective and abstract decision signals and are of relevance to the assumptions founding functional neuroimaging investigations of decision-making. Neural signatures of evidence accumulation have been isolated in numerous brain regions. Although animal neurophysiology has largely concentrated on effector-selective decision signals that translate the emerging decision into a specific motor plan, recent research on the human brain has isolated abstract neural signatures of decision formation that are independent of specific sensory and motor requirements. Here, we examine the functional distinctions between the two distinct classes of decision variable signal during decisions with deferred actions with and without foreknowledge of stimulus-effector mapping. We find salient distinctions in the dynamics of abstract versus effector-selective decision signals in the human brain, in terms of sustainment through response delays and contingency on foreknowledge of stimulus-response mapping.

How can we detect when language emerged?

Views differ radically as to how deep the roots of language lie in human phylogeny, largely because prior to the development of writing systems, this striking human attribute has to be inferred from indirect proxies preserved in the material record. Here I argue that the most appropriate such archaeological proxies encode the modern human symbolic cognitive system from which language emerges. Throughout the 2.5 million years or more for which an archaeological record has existed, change has been both sporadic and rare-until symbolic objects and behaviors begin to appear, well within the tenure of our highly apomorphic species Homo sapiens. I propose that the biology underwriting our unusual cognitive and linguistic systems was acquired in the major developmental reorganization that gave rise to our anatomically distinctive species around 200,000years ago in Africa. However, the material record indicates that this new potential lay fallow for around 100,000years, following which it was released by what was necessarily a behavioral stimulus. By far the best candidate for that stimulus is the spontaneous invention of language, which is plausibly underwritten by a relatively simple mental algorithm, and could readily have spurred symbolic cognitive processes in a feedback process. None of this means that earlier hominid vocal communication systems were not complex, or that extinct hominid species were not highly intelligent. But it does emphasize the qualitative distinctiveness of both modern symbolic cognition and language.

An Engraved Human Bone from the Mesolithic–Neolithic Site of Lepenski Vir (Serbia)

Post-mortem manipulations of the body were common at Mesolithic–Neolithic sites along the Danube River. During assessment of disarticulated human remains from Lepenski Vir, an unusual set of incisions (notches) were observed on the diaphysis of a human left radius along with a few cut-marks. Very few studies have attempted to distinguish clearly the characteristics of these modifications. All incisions were examined using a Scanning Electron Microscope and a Focus Variation Microscope that generated measurable three-dimensional digital models. Our results indicate that, on the basis of their micro-morphometric features, qualitative and quantitative distinctions can be made between cut-marks and notches, a methodology which can be applied to other engraved bones. Cut-marks, accidentally produced during flesh removal, were more irregular, longer, narrower and shallower than the notches. The notches, produced by a ‘nick and slice’ motion (pressure was applied to the bone, then the tool was pulled in one direction), were deliberately engraved. This engraved human bone is a rare example within a Prehistoric European context, possibly a form of notation, marking or counting a series of (important) events.

Adaptations for social cognition in the primate brain.

Studies of the factors affecting reproductive success in group-living monkeys have traditionally focused on competitive traits, like the acquisition of high dominance rank. Recent research, however, indicates that the ability to form cooperative social bonds has an equally strong effect on fitness. Two implications follow. First, strong social bonds make individuals' fitness interdependent and the 'free-rider' problem disappears. Second, individuals must make adaptive choices that balance competition and cooperation-often with the same partners. The proximate mechanisms underlying these behaviours are only just beginning to be understood. Recent results from cognitive and systems neuroscience provide us some evidence that many social and non-social decisions are mediated ultimately by abstract, domain-general neural mechanisms. However, other populations of neurons in the orbitofrontal cortex, striatum, amygdala and parietal cortex specifically encode the type, importance and value of social information. Whether these specialized populations of neurons arise by selection or through developmental plasticity in response to the challenges of social life remains unknown. Many brain areas are homologous and show similar patterns of activity in human and non-human primates. In both groups, cortical activity is modulated by hormones like oxytocin and by the action of certain genes that may affect individual differences in behaviour. Taken together, results suggest that differences in cooperation between the two groups are a matter of degree rather than constituting a fundamental, qualitative distinction.

The Four Cs of disaster partnering: communication, cooperation, coordination and collaboration.

Public, nonprofit and private organisations respond to large-scale disasters domestically and overseas. Critics of these assistance efforts, as well as those involved, often cite poor interorganisational partnering as an obstacle to successful disaster response. Observers frequently call for 'more' and 'better' partnering. We found important qualitative distinctions existed within partnering behaviours. We identified four different types of interorganisational partnering activities often referred to interchangeably: communication, cooperation, coordination and collaboration-the Four Cs. We derived definitions of the Four Cs from the partnering literature. We then tested them in a case study of the response to the 2010 Haiti earthquake. We suggest that the Four Cs are distinct activities, that organisations are typically strong or weak in one or more for various reasons, and that the four terms represent a continuum of increased interorganisational embeddedness in partnering activities.

The role of dimension relevance in features' access to response-selection mechanisms.

It is widely agreed that attending to a stimulus entails that all its features are processed. However, whether all these features are granted access to response-selection mechanisms remains a debated issue. Some authors suggest that all the features of the attended object affect response selection, irrespective of their relevance to the task at hand, whereas others claim that only its currently relevant features do. Yet others suggest that irrelevant features of an attended object affect response selection only if this object is the target, that is, only if it is selected for action. The results from 3 experiments show that responses associated with an attended object's irrelevant dimension interfered with response selection even when this object was not selected for action, but to a lesser extent than the responses associated with its relevant dimension. Our findings also show that interference from the irrelevant dimension can be masked when the response codes associated with the relevant and irrelevant dimensions compete. We suggest a parsimonious account of the findings from the extant literature that obviates the need to postulate a qualitative distinction between attention and selection for action.

Qualitative Distinction of Autotrophic and Heterotrophic Processes at the Leaf Level by Means of Triple Stable Isotope (C-O-H) Patterns.

Foliar samples were harvested from two oaks, a beech, and a yew at the same site in order to trace the development of the leaves over an entire vegetation season. Cellulose yield and stable isotopic compositions (δ13C, δ18O, and δD) were analyzed on leaf cellulose. All parameters unequivocally define a juvenile and a mature period in the foliar expansion of each species. The accompanying shifts of the δ13C-values are in agreement with the transition from remobilized carbohydrates (juvenile period), to current photosynthates (mature phase). While the opponent seasonal trends of δ18O of blade and vein cellulose are in perfect agreement with the state-of-art mechanistic understanding, the lack of this discrepancy for δD, documented for the first time, is unexpected. For example, the offset range of 18 permil (oak veins) to 57 permil (oak blades) in δD may represent a process driven shift from autotrophic to heterotrophic processes. The shared pattern between blade and vein found for both oak and beech suggests an overwhelming metabolic isotope effect on δD that might be accompanied by proton transfer linked to the Calvin-cycle. These results provide strong evidence that hydrogen and oxygen are under different biochemical controls even at the leaf level.
