Distinctive features
2023
Feature-based models of sign language use distinctive features to describe the phonological structure of signs. We use near-minimal pairs and phonological phenomena like productivity and neutralisation in French Sign Language to show that the feature [web], which refers to the webbing part of the fingers, should be (re)introduced into the list of phonologically active features. In discussing potential cases of [web] in other sign languages and the impact on the shape of phonological inventories, we first offer an account of [web] in terms of a location feature in line with most traditional feature-geometry models. We then offer some speculations on why a more uniform characterisation of [web] and the features in the same subclass in terms of the orientation type results in more economical models.

Language-dependent cue weighting in distinctive feature: evidence from the perception of Mandarin high vowels by native English speakers
2023
This study investigates the perception of the three Mandarin high vowels /i, u, y/ after dental, retroflex, and palatal fricatives and affricates (/s/-/ʦ/-/ʦʰ/; /ʂ/-/tʂ/-/tʂʰ/, and /ʨ/, /ʨʰ/, /ɕ/) by native English speakers. The results of the perceptual identification and categorization experiments show that among the three target vowels, the high front rounded vowel /y/ presents the greatest challenge for native English speakers. They have a significantly higher tendency to confuse /y/ with the Mandarin high-back rounded vowel /u/ compared to the Mandarin high-front unrounded vowel /i/, as they perceptually classified /y/ and /u/ into the same English vowel category /u/. The findings of the study suggest that native English speakers adopt a perceptual strategy that differs from that of native Japanese and Korean speakers, relying heavier on the feature of roundness as opposed to backness in perceiving the Mandarin /y/. This study contributes to the perceptual cue weighting field by examining the weighting of phonetic cues (i.e., distinctive features) in Mandarin high vowels by native English speakers. These results hold pedagogical significance as they highlight the importance of targeted perception training for learners of different language backgrounds to enhance both their recognition and reproduction of second language sounds.

Towards the most prägnant Gestalt: Leveling and sharpening as contextually dependent adaptive strategies
2025
Gestalt psychologists posited that we always organize our visual input in the best way possible under the given conditions. Both weakening or removing unnecessary details (i.e., leveling) and exaggerating distinctive features (i.e., sharpening) can contribute to achieving a better organization. When is a feature leveled or sharpened, however? We investigated whether the importance of a feature for discrimination among alternatives influences which organizational tendency occurs. Participants were simultaneously presented with four figures composed of simple geometrical shapes, and asked to reconstruct one of these figures in such a way that another participant would be able to recognize it among the alternatives. The four figures differed either qualitatively or only quantitatively (i.e., far or close context). Regarding quantitative differences, two feature dimensions were varied, with one manifesting a wider range of variability across the alternatives than the other. In case of a smaller variability range, the target figure was either at the extreme of the range or had an in-between value. As expected, the results indicated that sharpening occurred more often for the feature with an extreme value, for the feature exhibiting more variability, and for the features of figures presented in the close context, than for the feature with a non-extreme value, exhibiting less variability, or in the far context. In line with Metzger's (1941) definition of prágnant Gestalts, the essence of a Gestalt is context-dependent, and this will influence whether leveling or sharpening of a feature will lead to the best organization in the specific context.

What is Qualitative in Qualitative Research
2019
What is qualitative research? If we look for a precise definition of qualitative research, and specifically for one that addresses its distinctive feature of being “qualitative,” the literature is meager. In this article we systematically search, identify and analyze a sample of 89 sources using or attempting to define the term “qualitative.” Then, drawing on ideas we find scattered across existing work, and based on Becker’s classic study of marijuana consumption, we formulate and illustrate a definition that tries to capture its core elements. We define qualitative research as an iterative process in which improved understanding to the scientific community is achieved by making new significant distinctions resulting from getting closer to the phenomenon studied. This formulation is developed as a tool to help improve research designs while stressing that a qualitative dimension is present in quantitative work as well. Additionally, it can facilitate teaching, communication between researchers, diminish the gap between qualitative and quantitative researchers, help to address critiques of qualitative methods, and be used as a standard of evaluation of qualitative research.

What is so special about online (as compared to offline) hate speech?
There is a growing body of literature on whether or not online hate speech, or cyberhate, might be special compared to offline hate speech. This article aims to both critique and augment that literature by emphasising a distinctive feature of the Internet and of cyberhate that, unlike other features, such as ease of access, size of audience, and anonymity, is often overlooked: namely, instantaneousness. This article also asks whether there is anything special about online (as compared to offline) hate speech that might warrant governments and intergovernmental organisations contracting out, so to speak, the responsibility for tackling online hate speech to the very Internet companies which provide the websites and services that hate speakers utilise.

Platform-Capital’s ‘App-etite’ for Control
2020
This qualitative case study adopts a labour process analysis to unpack the distinctive features of capital’s control regimes in the food-delivery segment of the Australian platform-economy and assesses labour agency in response to these. Drawing upon worker experiences with the Deliveroo and UberEATS platforms, it is shown how the labour process controls are multi-facetted and more than algorithmic management, with three distinct features standing out: the panoptic disposition of the technological infrastructure, the use of information asymmetries to constrain worker choice, and the obfuscated nature of their performance management systems. Combined with the workers’ precarious labour market positions and the Australian political-economic context, only limited, mainly individual, expressions of agency were found.

Purpose: Some variability in children's early productions of grammatical morphemes reflects phonological factors. For example, production of 3rd person singular \"-s\" is increased in utterance-final versus utterance-medial position and in simple versus cluster codas (e.g., \"sees\" vs. \"hits\"). Understanding the factors that govern such variability is an important step toward modeling developmental processes. In this study, the authors examined the generality of these effects by determining whether position and coda complexity influence production of plural \"-s\", which phonologically manifests the same as 3rd person singular \"-s\". Method: The authors used an elicited imitation task to examine the speech of 16 two-year-olds. Eight plural nouns (half contained simple codas, half contained cluster codas) were elicited utterance-medially and utterance-finally. Acoustic analysis of each noun was used to identify acoustic cues associated with coda production. Results: Results showed that plural production was more robust in utterance-final versus utterance-medial position but equally robust in simple versus cluster codas. Conclusions: These findings extend positional effects on morpheme production to plural \"-s\". An effect of coda complexity was not observed for plural but was observed for 3rd person singular, which raises the possibility that the morphological representation proper influences the degree to which phonological factors affect morpheme production.

Brahmin Left Versus Merchant Right: Changing Political Cleavages in 21 Western Democracies, 1948–2020
2022
This article sheds new light on the long-run evolution of political cleavages in 21 Western democracies. We exploit a new database on the socioeconomic determinants of the vote, covering more than 300 elections held between 1948 and 2020. In the 1950s and 1960s, the vote for social democratic, socialist, and affiliated parties was associated with lower-educated and low-income voters. It has gradually become associated with higher-educated voters, giving rise in the 2010s to a disconnection between the effects of income and education on the vote: higher-educated voters now vote for the \"left,\" while high-income voters continue to vote for the \"right.\" This transition has been accelerated by the rise of green and anti-immigration movements, whose distinctive feature is to concentrate the votes of the higher-educated and lower-educated electorates. Combining our database with historical data on political parties' programs, we provide evidence that the reversal of the education cleavage is strongly linked to the emergence of a new \"sociocultural\" axis of political conflict.
Democracy of Credit
2017
In recent years, sociologists have noted the increasing centrality of credit for determining life chances in our society, but they have not given adequate attention to the credit market as a key site where individuals assert claims over economic resources. This article explores distinctive features of the credit transaction that differentiate claims making in the credit market from more familiar forms of claims making in the labor market. Rather than the quid pro quo exchange between formal equals that characterizes thewage relation, the extension of credit creates an obligation that marks the debtor as inferior to the creditor. The hierarchical and asymmetrical nature of the loan contract appears to erode the possibility for effective political demands in this arena. However, this article demonstrates that to the extent the status of “ownership” is institutionalized in the credit transaction, borrowers may be able to overcome some of the disadvantages associated with occupying the weaker position in an unequal relationship of exchange.

Articulatory phonetics
2011
In this article we describe a componential, articulatory approach to the phonetic description of the configuration of the four fingers. Abandoning the traditional holistic, perceptual approach, we propose a system of notational devices and distinctive features for the description of the four fingers proper (index, middle, ring, and pinky). Specifically, we suggest that the configuration of the fingers is best understood as a componential combination of the positions of each of the three joints of each finger.
