Till We Have Red Faces: Drinking to Signal Trustworthiness in Contemporary China

Evaluation of Different Types of Stimuli in an Event-Related Potential-Based Brain-Computer Interface Speller under Rapid Serial Visual Presentation.

Rapid serial visual presentation (RSVP) is currently a suitable gaze-independent paradigm for controlling visual brain-computer interfaces (BCIs) based on event-related potentials (ERPs), especially for users with limited eye movement control. However, unlike gaze-dependent paradigms, gaze-independent ones have received less attention concerning the specific choice of visual stimuli that are used. In gaze-dependent BCIs, images of faces-particularly those tinted red-have been shown to be effective stimuli. This study aims to evaluate whether the colour of faces used as visual stimuli influences ERP-BCI performance under RSVP. Fifteen participants tested four conditions that varied only in the visual stimulus used: grey letters (GL), red famous faces with letters (RFF), green famous faces with letters (GFF), and blue famous faces with letters (BFF). The results indicated significant accuracy differences only between the GL and GFF conditions, unlike prior gaze-dependent studies. Additionally, GL achieved higher comfort ratings compared with other face-related conditions. This study highlights that the choice of stimulus type impacts both performance and user comfort, suggesting implications for future ERP-BCI designs for users requiring gaze-independent systems.

Green or red faces? Tourist strategies when encountering irresponsible environmental behavior

ABSTRACT Tourists’ green behavior plays a significant role in sustainable tourism development. Most of the previous research considered tourists exert green behavior independently, neglecting the influences of tourist-to-tourist interaction and the culture they are embedded in. This study took Chinese tourists visiting two lake tourism destinations (West Lake in Hangzhou and Xianshan Lake in Huzhou) as the research respondents and aimed to examine how tourist-to-tourist interaction within different relationships impact tourist on-site green behavior in Chinese face-culture settings. Based on a qualitative research approach using the critical incident technique, 76 incidents were investigated involving 29 Chinese tourists with different backgrounds. This research showed that the encounters among tourists were affected by the types of relationships (family, friends, and strangers) and Chinese face culture (the desire to gain face and the fear of losing face). The results contribute to the sustainable tourism literature by taking into consideration various types of social interactions, which positively or negatively affect green behavior. Fresh insights are revealed on how face consciousness influences Chinese social interactions and green behavior in tourism. The analysis of social interactions among tourists provides a new perspective for destination management organizations to enhance green behavior and improve sustainable management practices.

Graph Theory Algorithms of Hamiltonian Cycle from Quasi‐Spanning Tree and Domination Based on Vizing Conjecture

In this study, from a tree with a quasi‐spanning face, the algorithm will route Hamiltonian cycles. Goodey pioneered the idea of holding facing 4 to 6 sides of a graph concurrently. Similarly, in the three connected cubic planar graphs with two‐colored faces, the vertex is incident to one blue and two red faces. As a result, all red‐colored faces must gain 4 to 6 sides, while all obscure‐colored faces must consume 3 to 5 sides. The proposed routing approach reduces the constriction of all vertex colors and the suitable quasi‐spanning tree of faces. The presented algorithm demonstrates that the spanning tree parity will determine the arbitrary face based on an even degree. As a result, when the Lemmas 1 and 2 theorems are compared, the greedy routing method of Hamiltonian cycle faces generates valuable output from a quasi‐spanning tree. In graph idea, a dominating set for a graph S = (V, E) is a subset D of V. The range of vertices in the smallest dominating set for S is the domination number (S). Vizing’s conjecture from 1968 proves that the Cartesian fabricated from graphs domination variety is at least as big as their domination numbers production. Proceeding this work, the Vizing’s conjecture states that for each pair of graphs S, L.

Influence of seeing a red face during the male–male encounters of mosquito-specialist spiders

Males of Evarcha culicivora, an East African jumping spider (Salticidae), have bright red faces. Here, we investigated how seeing a red face might influence a male's behaviour during encounters with another male. We applied black eyeliner to conceal the red on a male's face and measured the spectral properties of male faces with and without the eyeliner. Only the faces without eyeliner reflected in the long-wavelength range corresponding to red. In experiments over 2 days, where eyeliner was absent on the first day and present on the second, we compared how two groups of males responded to their mirror images. Face Group: eyeliner concealed their faces. Head Group: eyeliner was applied to the tops of the males' heads instead of on their faces. The males from both groups displayed to their mirror image as if it were a living same-sex conspecific. However, when they could see a red face, males in the face group escalated to higher levels of aggression to their mirror image and initiated displaying from farther away than when the red had been concealed. We also found that the influence of eyeliner was stronger for the face group than for the head group. These findings suggest that, when seeing a red face, E. culicivora males become more confident that the individual in view is another male.

State-of-the-art lasers and light treatments for vascular lesions: from red faces to vascular malformations.

Notable milestones in the treatment of vascular lesions have been achieved over the past century. Many cutaneous vascular lesions can be successfully treated with lightbased devices. In this review, we will discuss the treatment of port-wine birthmarks, lymphatic malformations, infantile hemangiomas, rosacea, venous lakes, pyogenic granulomas, cherry angiomas, and angiofibromas using lasers, total reflection amplification of spontaneous emission of radiation, intense pulsed light, and photodynamic therapy. In addition, for several of these diagnoses, we will review medical therapies that can be combined with light-based devices to provide enhanced results.

Using emoticons to encourage students to recycle

ABSTRACTUncovering inexpensive, simple techniques to encourage students to act in a pro-environmental manner is of critical importance. Through a four-week field study at a large, environmentally focused elementary school, it was found that placing negatively valenced emoticons (i.e., red frowny faces) on trash cans increased the proportion of recycled material from 22% to 44%. Subsequently, through a controlled laboratory study at a recognized “green” university, it was found that the negatively valenced emoticon increased the percentage of students who recycled their provided paper from 46% to 62%. Therefore, using emoticons as a complement to existing environmental education may be an easily implementable technique to positively change the recycling behavior of both older and younger students.

[End Page 276] "Ask not what your country can do for you; ask what you can do for your country." —President John F. Kennedy, Inaugural Address, 1961 Is colorblindness a queer form? There is something Black about spatial practices of incarceration and perishment that dehumanize living matter.1 The Brookes (fig. 1) is a figure for the flesh. The flesh is pressed into the Brookes and the Zong. The flesh becomes knowledge through art: Barbara Chase-Riboud's Echo of Lions (1989) and Djimon Honsou's performance in Amistad (1997); the illustration above and its reproductions; M. NourbeSe Philip's poetry and Amma Asante's film Belle. To the putative owners, speculators, and underwriters of these ships, the flesh was only so much precious metal temporarily suspended in a perishable state. Posterity, the potential for power to reproduce itself and its world through the flesh, spilled out of the hold of those ships. Out of the hold of those ships, the lonely, uncovered flesh of Michael Brown spilled out into the street. Millions of eyes to swarm around him spilled out of the hold. The uninvited ghost of Renisha McBride spilled out onto Theodore Wafer's porch. Olaudah Equiano, as he was pressed into the service of making a new world for others, recalled his own flesh being "hurried away even amongst the uncircumcised" and swept up into the hold along with "a people who did not circumcise, and ate without washing their hands."2 He would meet distant peoples who cooked in iron pots and sharpened their teeth; he would worry over whether he would be killed and if his flesh was "to be eaten by those white men with horrible looks, red faces, and loose hair."3 Elsewhere I have written about how Black skin and Black hair form the substrate for a variety of commercial and scientific practices that assign them quantifiable value even as they engender intimacy. Our skin and hair belong to us without determining the limits of our belonging because we are more than flesh. Our captors insist we have always been flesh, so we can be left to perish like Michael Brown and Renisha McBride. Like Equiano, we try to remember when we were pressed into the hold. Adapting the new materialism to the task of reckoning with the flesh demands a critique of form, and the work of Sylvia Wynter, Hortense Spillers, and Alex Weheliye articulates this demand in inspiring fashion.4 This work is all the more urgent in the wake of what Ian Haney Lopez terms "reactionary colorblindness," which he traces to the backlash against affirmative action and the contemporary "renewed penchant for the racial formalism which in an earlier and ignominious version helped defend Jim Crow oppression."5This doctrine finds expression in legal reasoning that equates affirmative action with reverse discrimination, "positing whites as black to justify heightened review, but blacks as white to deny the persistence of racial hierarchy."6 In the name of colorblindness, a perverse (queer) [End Page 277] return to disenfranchisement proceeds by enabling the faceless majority to "reconfigure the existing political process in a manner that creates a two-tiered system of political change, subjecting laws designed to protect or benefit discrete and insular minorities to a more burdensome political process than all other laws."7 Supreme Court Justice Sonia Sotomayor scrutinizes the form in which a concern for Equal Protection gets articulated in this new moment by meeting it with a timely critique of her own: a rarely cited "political-process doctrine." While the ahistorical claims lodged in the name of a strange (queer) resurgent formalism seek to unmake the humanity of racial minority subjects, the political-process doctrine comprises a new, materialist mode of vigilance toward the ruses of form. Attention to the processes by which Blackness loses its human form, as well as to the processes that enable the human to take on a...

Book Review: Beyond New Media: Discourse and Critique in a Polymediated Age, by Art Herbig, Andrew F. Herrmann, and Adam W. Tyma (Eds.).

Art Herbig, Andrew F. Herrmann, and Adam W. Tyma (Eds.). Beyond New Media: Discourse and Critique in a Polymediated Age. London: Lexington Books, 2015. 201 pp.What should we call a environment when it is, well, not anymore? How do we define and study what our media-soaked world has become, and what it says about us?That conversation, at least in terms of this book, began among its three editors and like-minded others in 2012. It was propelled by a perceived need to discover how one talks and, therefore, thinks about media. Were old words and concepts keeping us from realizing new and important ways in which media have already joined our lives? Is changing faster than the language we have to discuss it? What umbrella term could be used to refer to what was happening? It was clearly time to have the discussion: #WeNeedaWord, the editors decided (p. xiv), declaring and legitimizing it in true social media form with a hashtag they first used on Facebook (p. 164).When the word searchers began discussing in earnest, were red faces, raised voices, and slamming heads on tabletops, the introduction notes.All of us are trying to get to a place that makes sense in this environment we find ourselves in. There are many words out there (i.e., rhizome, secondary orality, convergence); however, those words seem insufficient to explore the diverse phenomena that we are experiencing. (p. xiv)They chose The ensuing book reflects their aim for a robust and multifaceted definition of the chosen word so that the conversation might continue.The term, earlier coined by Mirca Madianou and Daniel Miller, describes environments in which each medium operating within an environment interacts and exists in relation to other media. In the word the authors use poly to signify the many different forms that media take as well as the many possible interactions one might have with them.Convergence, it is noted, us understand the point at which we can send and receive multiple messages across platforms via a single technology (p. xix). Polymediation takes that a step further referring to the convergence of mediated moments (p. xx). Think, perhaps, of hashtags. They are organizing tools, modes of expression, and shapers of communities that in turn shape thoughts. In convergence, through concurrent use on more than one platform, they gain power and presence. Many make the jump into a widespread social consciousness where, seemingly, awareness of the hashtag and what it represents propels actions. Consider the political tentacles of #ArabSpring, a tag that arose in mid-December 2010 and now signifies, at a global level, upheavals and uprisings that began at that time in the Middle East.The edited collection's 10 authors broaden the original concept, chapter by chapter. Collectively, they illustrate how polymediation pervades the post-convergence world. They argue that we ourselves, not just our individual media platforms, are constantly surrounded and shaped by the processes of polymediation. Furthermore, they assert, we are increasingly defined by media while we define ourselves by our choices of which media we use and how we use them.Adam W. Tyma first provides needed context in his review of mass media history pre-polymediation. Then, in a chapter describing the characteristics of polymediation, Michelle Calka opens with discussion of ubiquity. The ubiquitous ability to connect, the expectations that those abilities bring (timely replies to text messages, perhaps), and the ways in which we conduct our lives-and portray our selves-because of our technological tools is an area that remains relatively unexplored. Deftly, and using well-known examples, Calka additionally probes three other defining elements.The concept of shape-shifting authorship (a marvelously evocative term for a remix culture that likes to share, comment, and create in technologically enabled ways) helps provide inclusivity for such diverse topics as copyright practices, one's relationship to property and original thought, and one's role in participatory tsunamis of Web-enabled sentiment. …

Black-faced, red faces: the potentials of humour for anti-racist action

ABSTRACTAmong incidences of everyday racism, offensive jokes are writ large as a way of establishing and maintaining social norms and policing the boundaries of the social body. Yet humour's possible deployment toward anti-racist ends constitutes an under-researched problem. This paper examines an incident of supposedly humorous blackface performance on an Australian family variety television show. The incident was notable as an occasion where humour was used with racist effects but also to anti-racist ends. Literature on anti-racist action commonly assumes that responses to racism should have the gravity commensurate to the problem. We argue that humour enables actors to take a ‘decommitted’ relationship to their actions, creating the perception of distance between themselves and the action. While this capacity to decommit enables racist actions to masquerade as ‘just a joke’, it may also form the basis of a less confrontational, but potentially powerful, form of anti-racist action.

A bricolage exploration in genkan space: tengu and adjunct TEFL in the Japanese university context

This paper reports on research focusing on a group of adjunct teachers of English employed in Japanese universities. Grounded in interpretive epistemology foregrounding constructionist traditions, this research employed bricolage as way of inquiring into, then representing, these teacher’s experiences utilising multi-perspectival, multi-theoretical and multi-methodological approaches. Employing elements of Turnerian liminality and blending these with Japanese cultural mythology, this paper explores participants’ experience, knowledge and identity. Through interviews and focus groups, participants (n = 43) gave voice to their lived world in Japanese universities locating their ‘place’ as simultaneously inside and outside the boundaries of mainstream Japanese society and universities. As ‘liminal personas’, participants likened themselves to a ‘necessary evil’ in the context of internationalising the curriculum. Thus, their condition is understood to be both ambiguous and paradoxical. The Japanese university is likened to genkan (a common architectural feature in Japanese houses resembling an entrance hall or transitional space between inside and outside worlds) space and employing Japanese mythology, it is argued these teachers share features attributed to Tengu (Tengu are goblin-like monsters in Japanese mythology with long noses and bright red faces who traditionally act in mischievous, disruptive ways).

Who cares? Experimental attention biases provide new insights into a mammalian sexual signal.

The effects of intrasexual and intersexual selection on male trait evolution can be difficult to disentangle, especially based on observational data. Male-male competition can limit an observer's ability to identify the effect of female mate choice independently from sexual coercion. Here, we use an experimental approach to explore whether an ornament, the red facial skin exhibited by male rhesus macaques (Macaca mulatta), might be involved in both female mate choice and male-male competition. We used a noninvasive experimental approach based on the looking time paradigm in a free-ranging setting, showing images of differently colored male faces to both adult females (N = 91) and males (N = 77), as well as to juveniles (N = 94) as a control. Results show that both adult females and males looked longer at dark red faces compared with pale pink ones. However, when considering the proportion of subjects that looked longer at dark red faces regardless of preference strength, only females showed a significant dark red bias. In contrast, juveniles did not show any preferences between stimuli, suggesting that the adult bias is not a consequence of the experimental design or related to a general sensory bias for red coloration among all age-sex classes. Collectively, these results support the role the ornament plays in female mate choice in this species and provide the first evidence that this ornament may play a role in male-male competition as well, despite a general lack of observational evidence for the latter effect to date.

From spiderling to senescence: ontogeny of color in the jumping spider,Habronattus pyrrithrix

The diverse colors of animals serve a variety of purposes, from acquiring mates to avoiding predators. Often, color patterns are not static throughout life, but change drastically during development, maturity, and senescence. While recent work has focused on the signaling value of vibrant colors in jumping spiders (Salticidae), we know very little about how colors change as spiders age; such information can provide a context for understanding the functions of and constraints on colorful traits. Focusing on Habronattus pyrrithrix Chamberlin 1924, our goals were to examine (1) the microscopic morphology of the colored body regions that males display to females during courtship (i.e., males' red faces, green legs, and white pedipalps), (2) how the colors of these regions as well as dorsal color patterns change during development prior to sexual maturity, and (3) how male condition-dependent red facial and green leg coloration changes as males age beyond sexual maturity. Although the bright white pedipalps and green legs of males appeared only upon sexual maturity, the sexes began to differentiate in facial coloration and dorsal patterning, with males developing red faces and conspicuous black and white dorsal patterning as young juveniles (ca. 2.5 mm in body length, or ca. 45% of their total mature adult body size). Even after maturity, color was not static; a male's green legs (but not red face) faded with age. Results are discussed in the context of potential functions of and constraints on color in salticids, and how they may change throughout an individual's lifetime.

Natural variation in condition-dependent display colour does not predict male courtship success in a jumping spider

In many animals, males display costly, condition-dependent ornaments to choosy females. Indicator models of sexual selection predict that females should choose mates based on natural variation in such traits. In Habronattus pyrrithrix jumping spiders, males have conspicuous, condition-dependent red faces and green legs that they display to cryptically coloured females during courtship. In a correlational study using field-collected spiders, we paired individual males with virgin females in the laboratory and found that natural variation in male coloration did not predict mating success (likelihood of copulation) or levels of female aggression. Rather, mating success was best predicted by male body condition. We then conducted an outdoor experiment under natural sunlight where we gave both virgin and mated females the choice between two simultaneously courting males, one with his facial coloration experimentally reduced and the other that received a sham treatment. Again, we found no relationship between male coloration and courtship success. Our previous studies have shown that the presence (versus absence) of red facial coloration improves courtship success, but here we found no evidence that more subtle natural variation in this trait has any effect on success. We discuss these findings in the context of complex signalling and species recognition in Habronattus. While many studies report negative results for condition-dependent quality signalling alongside positive ones, few discuss the implications of negative results. We argue that, as empirical data accumulate, we should move towards asking why some condition-dependent traits are consistently important to females while other equally condition-dependent traits are either ignored, or only matter in certain contexts.

Male ornamental coloration improves courtship success in a jumping spider, but only in the sun

Abstract In many animals, males display colorful ornaments to females during courtship, the effectiveness of which depends on the ambient lighting environment. While a variety of hypotheses exist to explain both presence of and variation in such traits, many propose that they function as signals and that their presence is required for or improves successful mating. In Habronattus pyrrithrix jumping spiders, males display brilliant, condition-dependent red faces and green legs to drab gray/brown females during courtship. We designed 2 experiments to first test if coloration is required for successful mating and then whether the role of color changes under varying light conditions. In Experiment 1, we paired individual males with virgin females under laboratory lighting and found that blocking either their red or green coloration, or both, had no effect on success (likelihood of copulation, copulation duration, latency to copulation, female aggression, or cannibalism) when compared with sham-treated males. In Experiment 2, we gave virgin females the choice between 2 simultaneously courting males, one with his red coloration blocked and the other that received a sham treatment, and ran trials outdoors in both the sun and the shade. Blocking red facial coloration reduced a male’s ability to approach a female, but only when courting in the sun. These results suggest that ornamental coloration is not required for mating in H. pyrrithrix, but that red coloration improves success in certain contexts. We discuss implications for the evolution of elaborate, multimodal courtship displays by animals that interact in variable environments.

Blood pressure as a drug target: what should we be measuring?

Clinicians and researchers have traditionally relied on esti-mates of systolic and diastolic pressure in the brachialartery to predict cardiovascular risk and guide individualtherapy. There is overwhelming evidence that usual BPmeasured in this way is a powerful predictor of future car-diovascular events [1],but the mechanistic link(s) betweenpressure and pathology (atheromatous disease and arte-rial thrombosis) is (are) incompletely understood.The dis-tinguished statistician Ronald Fisher (of‘Fisher’s exact test’)pointed out the excellent correlation between the inci-dence of lung cancer in the twentieth century and sales ofwashing machines in a tobacco-industry funded pamphletmocking the then available evidence that smoking causescancer. His point was that association does not prove cau-sality, but nor does it disprove it, and the subsequent evi-dence assembled by Richard Doll resolved the smoking/cancer issue definitively.Evidence from placebo-controlled randomized trialsshows that experimental interventions that lower brachialartery blood pressure also reduce cardiovascular events[2]. This not only underpins clinical decision making butalso supports the notion that high BP actually causes car-diovascular disease,rather than being a consequence of it.However, this is not the end of the story. Systolic and dias-tolic BP (SBP,DBP) are correlated with one another,both arelowered by drug treatment, but DBP behaves strikinglydifferently from SBP in predicting future risk.Subjects aged50–79 years in the Framingham cohort were groupedaccording to SBP ( 160 mmHg) tocontrol for the strong association between SBP on DBP andreduce the effect of SBP on risk within each group [3].DBPin each group was found to be

About some red faces

The term "red face" is reserved for lesions located exclusively or very predominantly on the face. Diagnosis is based on different data: date and mode of appearance, characteristics of the erythema, functional signs, and associated systemic manifestations. A case of red face can have an infectious origin, caused by vascular, congenital, or acquired lesions, or be caused by photodermatosis, or be the main location of inflammatory dermatosis or collagenosis, but depending on the clinical context, many other diagnoses can be suggested. A few observations are presented so as to discuss the management of red face in the atopic patient, the role played by ultraviolet rays in the cutaneous lesions of dermatomyositis, as well as the diagnostic criteria of polymorphous light eruption, and lupus erythematosus.

Dermocosmetic management of the red face and rosacea

Erythematotelangiectatic rosacea is a frequent condition and affected patients benefit from medical treatments and dermatological procedures but also a complementary dermocosmetic assistance that aims at obtaining optimal skin comfort and preventing irritation of these particularly overreactive skins. Choice of dermocosmetics is crucial - especially in respect to their texture and the simplicity in ingredients - in order to optimize the application of the products and their tolerance. The addition of soothing and decongestant active ingredients is particularly important. Finally, photoprotection and a specific medical make-up are useful to attenuate the unattractive appearance of "red faces".

Modeling Single-Trial ERP Reveals Modulation of Bottom-Up Face Visual Processing by Top-Down Task Constraints (in Some Subjects).

We studied how task constraints modulate the relationship between single-trial event-related potentials (ERPs) and image noise. Thirteen subjects performed two interleaved tasks: on different blocks, they saw the same stimuli, but they discriminated either between two faces or between two colors. Stimuli were two pictures of red or green faces that contained from 10 to 80% of phase noise, with 10% increments. Behavioral accuracy followed a noise dependent sigmoid in the identity task but was high and independent of noise level in the color task. EEG data recorded concurrently were analyzed using a single-trial ANCOVA: we assessed how changes in task constraints modulated ERP noise sensitivity while regressing out the main ERP differences due to identity, color, and task. Single-trial ERP sensitivity to image phase noise started at about 95–110 ms post-stimulus onset. Group analyses showed a significant reduction in noise sensitivity in the color task compared to the identity task from about 140 ms to 300 ms post-stimulus onset. However, statistical analyses in every subject revealed different results: significant task modulation occurred in 8/13 subjects, one showing an increase and seven showing a decrease in noise sensitivity in the color task. Onsets and durations of effects also differed between group and single-trial analyses: at any time point only a maximum of four subjects (31%) showed results consistent with group analyses. We provide detailed results for all 13 subjects, including a shift function analysis that revealed asymmetric task modulations of single-trial ERP distributions. We conclude that, during face processing, bottom-up sensitivity to phase noise can be modulated by top-down task constraints, in a broad window around the P2, at least in some subjects.

Condition dependence of male display coloration in a jumping spider (Habronattus pyrrithrix)

In many animals, conspicuous coloration functions as a quality signal. Indicator models predict that such colors should be variable and condition dependent. In Habronattus pyrrithrix jumping spiders, females are inconspicuously colored, while males display brilliant red faces, green legs, and white pedipalps during courtship. We tested the predictions of the indicator model in a field study and found that male body condition was positively correlated with the size, hue, and red chroma of a male’s facial patch and negatively correlated with the brightness of his green legs. These traits were more condition dependent than non-display colors. We then tested a dietary mechanism for condition dependence using two experiments. To understand how juvenile diet affects the development of coloration, we reared juvenile spiders on high- and low-quality diets and measured coloration at maturity. To understand how adult diet affects the maintenance of coloration, we fed wild-caught adults with high- or low-quality diets and compared their coloration after 45 days. In the first experiment, males fed high-quality diet had redder faces, suggesting that condition dependence is mediated by juvenile diet. In the second experiment, red coloration did not differ between treatments, suggesting that adult diet is not important for maintaining the color after it is produced at maturity. Diet had no effect on green coloration in either experiment. Our results show different degrees of condition dependence for male display colors. Because red is dependent on juvenile diet, it may signal health or foraging ability. We discuss evidence that green coloration is age dependent and alternatives to indicator models for colorful displays in jumping spiders.
