Spin-glass behavior of Sn0.9Fe3.1N: An experimental and quantum-theoretical study
Authors: Scholz Tanja , Dronskowski Richard
Published: May 2016

Based on comprehensive experimental and quantum-theoretical investigations, we identify Sn0.9Fe3.1N as a canonical spin glass and the first ternary iron nitride with a frustrated spin ground state. Sn0.9Fe3.1N is the end member of the solid solution SnxFe4−xN (0 < x ≤ 0.9) derived from ferromagnetic γ′-Fe4N. Within the solid solution, the gradual incorporation of tin is accompanied by a drastic weakening of the ferromagnetic interactions. To explore the dilution of the ferromagnetic coupling, the highly tin-substituted Sn0.9Fe3.1N has been magnetically reinvestigated. DC magnetometry reveals diverging susceptibilities for FC and ZFC measurements at low temperatures and an unsaturated hysteretic loop even at high magnetic fields. The temperature dependence of the real component of the AC susceptibility at different frequencies proves the spin-glass transition with the characteristic parameters Tg  =  12.83(6) K, τ* = 10−11.8(2) s, zv = 5.6(1) and ΔTm/(Tm ⋅ Δlgω) = 0.015. The time-dependent response of the magnetic spins to the external field has been studied by extracting the distribution function of relaxation times g(τ, T) up to Tg from the complex plane of AC susceptibilities. The weakening of the ferromagnetic coupling by substituting tin into γ′-Fe4N is explained by the Stoner criterion on the basis of electronic structure calculations and a quantum-theoretical bonding analysis.
A subsequent closed-form description of propagated signaling phenomena in the membrane of an axon
Authors: Melendy Robert. F.
Published: May 2016

I recently introduced a closed-form description of propagated signaling phenomena in the membrane of an axon [R.F. Melendy, Journal of Applied Physics 118, 244701 (2015)]. Those results demonstrate how intracellular conductance, the thermodynamics of magnetization, and current modulation, function together in generating an action potential in a unified, closed-form description. At present, I report on a subsequent closed-form model that unifies intracellular conductance and the thermodynamics of magnetization, with the membrane electric field, Em. It’s anticipated this work will compel researchers in biophysics, physical biology, and the computational neurosciences, to probe deeper into the classical and quantum features of membrane magnetization and signaling, informed by the computational features of this subsequent model.

Authors: Cao L. P. , Jin M. L. , Li W. M. , Wang X. C. , Liu Q. Q. , Xu Y. L. , Pan L. Q. , Jin C. Q.
Published: May 2016

The bulk Ca2CrO4 samples were synthesized under high pressure and high temperature conditions using CaO and CrO2 as starting materials. The structure of the prepared Ca2CrO4 solid is characterized by X-ray diffraction with Rietveld refinement as tetragonal structure with the space group I41/acd. The CrO6 octahedrons elongate along c axis and rotate in ab plane. DC and AC magnetic susceptibility measurement results indicate spin glass behavior at low temperature. Temperature dependence of resistivity measurement results show Ca2CrO4 is an insulator at both ambient condition and high pressure.
Thai native chicken meat: an option to meet the demands for specific meat quality by certain groups of consumers; a review
Authors: Jaturasitha S. , Chaiwang N. , Kreuzer M.
Published: May 2016

Native chickens are slowly growing indigenous chicken (Gallus domesticus) breeds; many of them were developed from jungle fowl, which is found in every part of Asia. These breeds are disease resistant, easy adapting to tropical climates, and have a low mortality. In Thailand, a distinct sector of consumers prefers to eat meat from native chickens rather than that from broilers because it is more tasty and chewy. In addition, studies have shown that it has a low content of fat which may be helpful for people susceptible to coronary heart diseases. This review also compiles evidence for further indicators of a special meat quality such as more oxidative (Type I) muscle fibres, a higher collagen content (promoting the preferred chewiness), an elevated content of certain flavor-relevant compounds, as well as high ratio of polyunsaturated to saturated fatty acids.
Fairy-Tale Symbolism: An Overview
Authors: Vaz da Silva Francisco
Published: May 2016

Because the marvelous elements in fairy tales call for an explanation, a cohort of bright minds have pored over the problem of fairy-tale symbolism. Models sharing the nineteenth-century penchant for genetic inquiries have assumed that symbols are the survivals of archaic metaphors. Thus, Max Müller proposed that myths and fairy tales stem from obscured metaphors about solar phenomena; Sigmund Freud speculated that fairy-tale symbolism is the fossilized residue of primordial sexual metaphors; and Carl Jung submitted that symbols express immanent archetypes of the human psyche. Such early approaches assume that symbols convey fixed meanings, and they disregard the effects of folklore variation on meanings.

Jacob and Wilhelm Grimm did take variation into account. They conceived Märchen in terms of immanent blueprints incessantly recreated in myriad retellings, but they never tried to make sense of the themes by means of the variants. This path was taken by folklorists influenced by Freud. Alan Dundes proposed to harness tale variants to grasp symbolic equivalences, and he pioneered the study of folk metaphors. But Dundes focused on preset Freudian symbols, a trend that Bengt Holbek followed. To this day, the prospect of addressing fairy-tale symbolism beyond Freud’s assumption of fixed translations remains elusive.

Nevertheless, the basic tools are available. Maria Tatar remarked that fairy tales are metaphoric devices, and Claude Lévi-Strauss pointed out that metaphors—in switching terms that belong to different codes—lay bare the broader semantic field underlying each transposition. Müller, Freud, Dundes, Tatar, and Lévi-Strauss variously glimpsed metaphoric patterns in tale variations. The time is ripe to synthesize these intuitions in the light of contemporary cognitive research on conceptual metaphor, so as to address the creative dynamics of symbolism in fairy tales.
E-Learning, Information Technology, and Student Success in Higher Education
Authors: Long Kim Cliett
Published: May 2016

E-learning expands options for teaching and learning using technology. This nomenclature has been solidly in use for the last ten years. The expansive and ever fertile frontier of e-learning—a term used interchangeably with distance and online learning—has become standard fare as an educational delivery solution designed to enhance knowledge and performance. Many educational institutions, corporate enterprises and other entities are utilizing web-based teaching and learning methodologies to deliver education either partially or wholly online using electronic platforms. The learning value chain, including management and delivery, has created multimodal systems, content, and processes to increase accessibility, measurability, and cost effectiveness by infusing advanced learning techniques, such as adaptive learning or communities of practice, among students, employee groups, and lifelong learners. It is interesting to note that e-learning encapsulates internet based courseware and all other asynchronous and synchronous learning, as well as other capabilities for supporting learning experiences.

Student success and advancements in technology are now inextricably linked as a result of higher education institutions embracing and offering e-learning options. The absence of direct instructor guidance makes distance learning particularly difficult for some students. Certain students struggle with the lack of guidance inherent in online learning and the requisite need to work independently. In particular, the lack of high touch strategies in e-learning often leads students to drop or fail courses. While some students struggle to remain engaged in technology-enabled learning, technology is often the vehicle for keeping these same students on task. There are a variety of electronic tools designed to augment online learning and keep online learners on task. Podcasts, for example, can be easily downloaded, then played back on a student’s media player or mobile device at a later date. The student is not tied to a computer, which results in a more comprehensive learning experience.

In many cases, e-learning has become a very lucrative and desirable marketplace for higher education institutions. The business case for e-learning is a clarion call for tight integration among business, human resources, and knowledge and performance management. Hence, it is incumbent upon educational institutions to instill approaches that focus on the learner, learning, and improved performance, more so than the tools and technology. Of further importance is the need for higher education institutions to provide stratagems for developing and supporting caring online relationships, individualized student environments, collaboration, communication, and e-learning culture. Ultimately, institutions should measure not only improved business and performance, but also improved student online learning aptitudes (more self-motivated, self-directed, and self-assessed learning).
Race and Ethnicity in US Media Content and Effects
Authors: Mastro Dana
Published: May 2016

Research empirically investigating the influence of media exposure on issues of race and ethnicity has long documented that media use meaningfully impacts the cognitions, emotions, and behaviors of audience members. Certainly, media are only one among a number of factors that contribute to perceptions regarding (and actions toward) one’s own and other racial/ethnic groups. However, theory and empirical evidence consistently demonstrate that the manner in which racial/ethnic groups are characterized in the media can harm or benefit different groups, depending on the nature of these depictions (alongside other social and psychological determinants). Consequently, it is both practically and theoretically important to both identify how and how often different groups are portrayed across the media landscape as well as to assess the ways in which exposure to this content influences media audiences.

What quantitative content analytic studies have revealed is that there is variation in depictions of race/ethnicity in US media depending on the group, the medium, and the genre. Thus, whereas Blacks have achieved a degree of parity when it comes to the quantity of depictions on primetime U.S. television, there is variation in the quality depending on the genre. Further, the same advances have not been seen for Blacks in news, in film, and across other media forms and platforms. For Latinos, little has changed across decades when it comes to numeric representation in the media. When it comes to the quality of these portrayals, although some of the more egregious media stereotypes have faded, other long-standing media definitions of Latinos remain persistent. For other racial/ethnic groups, few images are presented. Within these infrequent images, a constrained set of characterizations often predominates, such as spiritual American Indians, tech-savvy Asian Americans, and terrorist Muslims.

Exposure to these representations has consequences. Consuming the images and messages associated with racial/ethnic groups in the media contributes to the formation, activation, and application of racial/ethnic cognitions. For racial/ethnic majority group members (i.e., whites), unfavorable media depictions can mean the perpetuation of harmful stereotypes: this can lead to outcomes ranging from unsympathetic policy positions to active or passive harming behaviors. When media characterizations are favorable, more auspicious outcomes emerge. For the racial and ethnic groups being depicted, the effects of exposure again depend on the quantity and quality of portrayals. Negative characterizations prompt shame, anger, and other undesirable emotions and lead to esteem problems. On the other hand, some research indicates that favorable characterizations can serve as a source of group pride, which boosts esteem.
Leadership from a Communication Perspective
Authors: Tourish Dennis
Published: May 2016

Leadership has fascinated people from antiquity and has been studied extensively by academics for many decades. A variety of theoretical perspectives have taken hold—most notably that of transformational leadership—and have sought to explore the processes whereby leaders influence followers, to delineate the factors that put limits on such influence, and to determine the interrelationship between the attributes that leaders bring to their role and the contexts in which they find themselves. There has also been a growing interest in followership and how the behaviors, cognitions, and emotions of followers both contribute to organizational and group outcomes and help to shape leader behavior. The issue of followership, however, remains very much a nascent area of inquiry within the broader field of leadership studies.

Recently, explicitly communication perspectives have been brought more frequently to bear on leadership studies. This has assumed two main forms. First, “discursive leadership” has looked at both the linguistic mechanisms by which leader action and effects take place and how larger frames of leadership discourse can be said to constitute both broader leader–follower dynamics and our understanding of them. Associated with this, some complexity leadership theorists have stressed the “relational” dynamics implicit to leadership processes as a means of countering what they see as an excessive focus on the traits and actions of individual leaders. These approaches emphasize the importance of context and the relational dynamics between leaders and followers embedded in such contexts. Second, some communication scholars influenced by process theories of organization have begun to sketch out the means whereby communication is central to how organizational actors make, refuse, and enact claims to leadership agency, particularly in contexts where such claims may be contested by many. The role of follower dissent and power relations more generally is viewed as a crucial area of inquiry.

Accordingly, communication approaches to leadership have adopted a variety of theoretical perspectives. Many scholars from communication backgrounds have researched communication processes whereby leaders influence others. More recently, critically oriented communication scholars have explored the often conflicted dynamics between leaders and followers, focusing on such issues as power, domination, and control and their implications for leadership theory. Both explicitly and implicitly, these have therefore challenged dominant leadership perspectives, particularly but not exclusively that of transformational leadership.
Conversation Analysis and News Interviews
Authors: Loeb Laura , Clayman Steven E.
Published: May 2016

The news interview is a prominent interactional arena for broadcast news production, and its investigation provides a window into journalistic norms, press-state relations, and sociopolitical culture. It is a relatively formal type of interaction, with a restrictive turn-taking system normatively organized around questions and answers exchanged for the benefit of an audience. Questions to politicians are sensitive to the journalistic norms of neutralism and adversarialness. The neutralism norm is relatively robust, implemented by interviewers adhering to the activity of questioning, and avoiding declarative assertions except as prefaces to a question or as attributed to a third party. The adversarialism norm is more contextually variable, implemented through agenda setting, presupposition, and response preference, each of which can be enhanced through question prefaces. Adversarial questioning has increased significantly in the United States over time, and in some other national contexts. Adversarial questioning creates an incentive for resistant responses from politicians, which are managed with overt forms of damage control and covert forms of concealment. News interviews with nonpartisan experts and ordinary people are generally less adversarial and more cooperative. Various hybrid interview genres have emerged in recent years, which incorporate practices from other forms of broadcast talk (e.g., celebrity talk shows, confrontational debates) within a more loosely organized interview framework. These hybrid forms have become increasingly prominent in contemporary political campaigns and current affairs discussions.
Communities of Practice
Authors: Andrew Nicola
Published: May 2016

This is an advance summary of a forthcoming article in the Oxford Research Encyclopedia of Communication. Please check back later for the full article.

A Community of Practice (CoP) is an approach to professional learning and development based on collaboration among peers. In a CoP, individuals come together virtually or physically and coalesce around a common purpose. CoPs are defined by knowledge rather than task and provide a safe space for novices and experienced practitioners to collaborate, construct, and embed sustainable outputs that impact on both theory and practice development.

CoPs provide a framework for constructing authentic and collaborative learning. Jeanne Lave and Etienne Wenger are credited with the original description of a CoP as an approach to learning that encompasses elements of identity, situation, and active participation. CoPs blend a constructivist view of learning, where meaningful experience is set in the context of “self” and the relationship of “self” with the wider professional community. The result is an integrated approach to learning and development achieved through a combination of social engagement and collaborative working in an authentic practice environment.

In health and education, CoPs blend theory and practice to create a portal for practitioners to generate, shape, test, and evaluate new ideas and innovations. CoPs learn through the act of social participation; active group learning, and collaboration in an authentic practice environment. Membership of a CoP supports the development of professional identity within a wider vocational sphere.
The Biology Of Affection
Authors: Floyd Kory , Ray Colter D.
Published: May 2016

Affectionate communication comprises the verbal and nonverbal behaviors people use to express messages of love, appreciation, fondness, and commitment to others in close relationships. Like all interpersonal behaviors, affectionate communication has biological and physiological antecedents, consequences, and correlates, many of which have implications for physical health and wellness. Investigating these factors within a biological framework allows for the adjudication of influences beyond those attributable to the environment. In particular, there are observable genetic and neurological differences between individuals with a highly affectionate disposition and those less prone to communicating affection, suggesting that variance in the tendency to engage in affectionate behavior is not entirely the result of environmental influences such as enculturation, parenting, and media exposure. In addition, the expression of affection is associated with markers of immune system competence and appears to help the body to relax and remain calm. The biological effects of affectionate communication are perhaps most pronounced in situations involving either acute or chronic stress. Specifically, highly affectionate individuals are less likely than others to overreact physiologically to stress-inducing events. Whatever stress reaction they do mount is better regulated than among their less affectionate counterparts. Moreover, highly affectionate individuals—or simply those who receive expressions of affection prior to or immediately following a stressful situation—exhibit faster physiological recovery from their elevated stress. Perhaps unsurprisingly, therefore, being deprived of adequate affectionate communication is predictive of multiple physical and psychological detriments, including elevated stress and exacerbated depression, social and relational problems, insecure attachment, susceptibility to diagnosed anxiety and mood disorders, susceptibility to diagnosed secondary immune disorders, chronic pain, and sleep disturbances.
Religion, Culture, and Communication
Authors: Croucher Stephen M. , Zeng Cheng , Rahmani Diyako , Sommier Mélodine
Published: May 2016

Religion is an essential element of the human condition. Hundreds of studies have examined how religious beliefs mold an individual’s sociology and psychology. In particular, research has explored how an individual’s religion (religious beliefs, religious denomination, strength of religious devotion, etc.) is linked to their cultural beliefs and background. While some researchers have asserted that religion is an essential part of an individual’s culture, other researchers have focused more on how religion is a culture in itself. The key difference is how researchers conceptualize and operationalize both of these terms. Moreover, the influence of communication in how individuals and communities understand, conceptualize, and pass on religious and cultural beliefs and practices is integral to understanding exactly what religion and culture are.

It is through exploring the relationships among religion, culture, and communication that we can best understand how they shape the world in which we live and have shaped the communication discipline itself. Furthermore, as we grapple with these relationships and terms, we can look to the future and realize that the study of religion, culture, and communication is vast and open to expansion. Researchers are beginning to explore the influence of mediation on religion and culture, how our globalized world affects the communication of religions and cultures, and how interreligious communication is misunderstood; and researchers are recognizing the need to extend studies into non-Christian religious cultures.
Rhetorical Approaches to Health and Medicine
Authors: Malkowski Jennifer A. , Scott J. Blake , Keränen Lisa
Published: May 2016

Rhetoric, commonly understood as the art, practice, and analysis of persuasion, has longstanding connections to medicine and health. Rhetorical scholars, or rhetoricians, have increasingly applied rhetorical theories, concepts, and methods to the texts, contexts, discourses, practices, materials, and digital and visual artifacts related to health and medicine. As an emerging interdisciplinary subfield, the rhetoric of health and medicine seeks to uncover how symbolic patterns shape thought and action in health and medical texts, discourses, settings, and materials.

In practice, rhetoricians who study health and medicine draw from the standard modes of rhetorical analysis, such as rhetorical criticism and rhetorical historiography, as well as from social science methods—including participant observation, interviewing, content analysis, and visual mapping—in order to deepen understanding of how language functions across health and medical objects, issues, and discussions. The objects of analysis for rhetorical studies of health and medicine span medical research, education, and clinical practice from laboratory notes to provider–patient interaction; health policymaking and practice from draft policies through standards of care; public health texts and artifacts; consumer health practices and patient advocacy on- and offline; public discourses about disease, death, bodies, illness, wellness, and health; online and digital health information; popular entertainments and medical dramas; and alternative and complementary medicine. Despite its methodological breadth, rhetorical approaches to science and medicine consistently involve the systematic examination and production of symbolic exchanges occurring across interactional, institutional, and public contexts to determine how individuals and groups create knowledge, meanings, identities, understandings, and courses of action about health and illness.
Sexual Media Content and Effects
Authors: Ward Lucretia Monique , Erickson Sarah E. , Lippman Julia R. , Giaccardi Soraya
Published: May 2016

Major findings concerning the nature and impact of sexual content in mainstream entertainment media, with a focus on empirical studies and content analyses (published from 2000 to 2015) indicate that sexual content is prevalent in mainstream media, appearing in approximately 85% of films and 82% of television programs. On television, sexual content varies greatly by genre, sexual talk is more prevalent that depictions of sexual activity, and references to sexual risks and responsibilities are minimal. Sexual imagery is also prevalent in music videos, where the most frequent portrayals are of sexual and suggestive dance, sexual objectification, and self-touching. Women and female artists are more often shown in sexual ways than men and male artists. This trend extends to video games, where women are underrepresented, and, when present, are much more likely than men to be shown with a sexualized appearance or in sexually revealing clothing.

Drawing primarily on the premises of cultivation theory and social cognitive theory, researchers have explored how exposure to this content contributes to the sexual attitudes and behaviors of consumers. In terms of attitudes, heavier media exposure is associated with holding more positive attitudes toward uncommitted sexual exploration; stronger support of gender-related sexual roles, adversarial sexual beliefs, and the sexual double standard; and increased estimates of peers’ sexual behavior. Evidence is sparser for a causal link between media use and attitudes toward uncommitted sexual exploration. In terms of sexual behavior, cross-sectional surveys have found that frequent exposure to sexual media content is associated with increased reports of intentions to have sex, light sexual behavior (kissing, holding hands), and heavy sexual behavior, such as intercourse. Studies have also found that heavier exposure to sexual content predicts earlier or heavier sexual activity one year later. Several factors have been shown to moderate these connections, including the race and gender of the viewer and level of parental mediation.

Sexually explicit material or pornography has become widely accessible, especially on the Internet. Among both adolescents and adults, more frequent pornography consumption has been associated with holding more permissive sexual attitudes, such as a greater acceptance of extramarital and casual sex; with gender-specific attitudes, including greater support of traditional sexual roles and adversarial sexual beliefs; and with a greater likelihood of perpetrating sexual coercion, harassment, and aggression. Evidence also connects pornography consumption to individual sexual behavior, especially among adults. Among adults, pornography use is linked to earlier coital initiation, more frequent participation in specific sexual activities, participation in casual sex, and having a higher number of sexual partners; it has not been consistently linked to condom use.
Technologized Interaction
Authors: Meredith Joanne
Published: May 2016

As the use of online technologies has grown in recent years, so has the study of computer-mediated communication.

Online communication began in universities through the use of e-mail. Soon, spaces such as multi-user dungeons (MUDs), Listserv, and bulletin boards were developed, which not only allowed people who knew each other offline to interact but also enabled individuals who were not previously acquainted to communicate via the Internet. The development of Web 2.0, which allowed for more user-generated content, led to new and innovative ways of interacting online, most notably thorough social media sites. Social media sites, such as Facebook and Twitter, allow not only for text-based interaction to occur but also for image- and video-based interaction.

Through all these developments, interactional norms and practices have developed. A key factor in these norms is what the medium enables, or affords, participants to do. Features such as whether an interactional platform is synchronous or asynchronous can impact the nature of the interaction. Similarly, the lack of visual or verbal contact when interacting may impact upon the interaction, through the potential for misunderstandings. Participants do, though, develop practices to suit the medium. If we examine these practices in detail, it is possible to also analyze the role which technology plays in the interaction. One method that has been used to do this is conversation analysis, which was developed for and using spoken interaction. Conversation analysis examines conversation in forensic detail to illuminate the norms and practices through which we conduct our everyday lives. In using this method for analyzing online interaction, we can not only understand the practices but also examine the affordances of particular interactional platforms.

Various interactional features of computer-mediated communication (CMC) have been examined from a conversation analytic perspective, including sequential organization, openings, turn-taking, and repair. A common focus of these studies it to explore the interactional patterns but also to understand how these might be impacted by the technology itself. The development of norms for a variety of forms of technologized interaction demonstrates how individuals are capable of adapting their interactional practices for new contexts.
Listening
Authors: Bodie Graham D.
Published: May 2016

Listening is recognized as a multidimensional construct that consists of complex (a) affective processes, such as being motivated to attend to others; (b) behavioral processes, such as responding with verbal and nonverbal feedback; and (c) cognitive processes, such as attending to, understanding, receiving, and interpreting content and relational messages. Research in the communication studies discipline has focused most heavily on the cognitive processes of listening with the least attention afforded to behavioral components. Although several models of listening have been put forward, scholars still struggle with basic notions of how best to define listening for research purposes and how to incorporate listening into mainstream theoretical frameworks. Contemporary scholarship explores intersections between listening and cultural studies research as communication scholars come to participate in larger discussions of the auditory environment. At the start of the 21st century, listening research is just one of the many sites where communication studies is making a contribution to interdisciplinary research across the humanities and social sciences.
Communication Campaigns that Emphasize Environmental Influences on Health and Risk
Authors: Silk Kami J. , Sheff Sarah , Lapinski Maria , Hoffman Alice
Published: May 2016

The environment influences health and risk outcomes, and communication campaigns often strive to reduce risk and promote positive health outcomes by raising awareness, increasing knowledge, influencing attitudes, and impacting intentions and behavior. Communication campaigns should be based on good formative research and theory, and they should be implemented with fidelity and a clear evaluation plan. Communication campaigns that address environmental influences are typically focused on promoting human, animal, or environmental outcomes despite the fact that all three are interconnected and would benefit from being considered in a larger ecological framework. The One Health approach reconceptualizes environmental influences by focusing not just on the environmental but also connections with human and animal health. One Health can be applied to communication campaigns to support efforts that acknowledge and promote the complexity of these relationships. Campaigns about environmental influences on health and risk range from a longstanding campaign built on individual activities to reduce environmental and personal risk to a sun smart campaign to reduce sun exposure risk to a lead-free campaign and an asthma-control campaign concerned about air quality. Other environmental campaigns focus on tobacco prevention, obesity prevention by addressing environmental influences as part of their strategy, climate control, and ocean species preservation—and that is only a sampling of popular campaign topics. These communication campaigns face similar challenges like lack of formative research and evaluation plans as well as atheoretical approaches to influence outcomes.
Gay Straight Communication
Authors: Fasoli Fabio
Published: May 2016

Sexual orientation is a private matter that individuals can decide to disclose or conceal. Nevertheless, when interacting with others, people look for cues of sexual orientation. Hence, the person’s face, voice, or non-verbal behavior is taken as a cue revealing sexual orientation. As research on “gaydar” has shown, this detecting ability can sometimes be accurate or stereotype-based. Sometimes gay, lesbian, and bisexual people themselves intentionally communicate their sexual identity explicitly or through more subtle cues. Intentional or not, several cues are taken as communicating sexual orientation with the consequences of shaping interpersonal interactions.

Identifying someone as gay or lesbian has several implications. On the one hand, it leads straight men and women to non-verbally behave differently than when interacting with other straight individuals (e.g., more physical distance, more self-touching). On the other hand, it also affects verbal communication (e.g., topics of conversation, questions, and statements). The harshest consequence is hate speech and homophobic language. Research has shown that being labeled as “faggot” or “dyke” not only negatively affects those who are the target of such verbal derogation but also negatively impacts on straight bystanders. Indeed, gay and lesbian targets of homophobic language report a lower level of well-being and self-acceptance, while being exposed to such language increases prejudice toward gay men and lesbians among straight people. In the case of straight men, the use of homophobic language is often associated with identity self-affirmation and self-presentation. Interestingly, a recent trend among gay people has been noticed: they use homophobic labels among them as a form of “reclaimed language,” meaning that these derogatory terms are used with a different intent and reframed in a more positive way.

Moreover, communicating sexual orientation can increase self-acceptance, social support, and positive social comparison among gay men and lesbians and can also increase positive attitudes toward gay people, especially when it happens with friends and family members.
Hegemony in Marxist Traditions
Authors: Briziarelli Marco , Hoffmann Jeff
Published: May 2016

Hegemony generally refers to the mechanisms and dynamics describing how a determinate group comes to organize its ruling at multiple levels, such as the political economic, social, cultural, and linguistic. In communication studies, the term is almost automatically associated with the particular conceptualization of Marxist thinker Antonio Gramsci, who provides a way to describe and explore the critical link between “power,” culture, and communicative practices. However, different readings of Gramscian hegemony, mediated by different traditions inside the discipline, have produced competing and evolving definitions. The common trait of all these approaches is an interpretation that tends to privilege “consent” over “coercion,” “leadership” over “domination,” and “civil society” over the “state.” Finally, a narrative is provided regarding how the concept gradually moved out of its Marxist origin to become a more sociologically abstract account of organized asymmetric power relations.
Post-Structuralism
Authors: Crick Nathan A.
Published: May 2016

Poststructuralism represents a set of attitudes and a style of critique that developed in critical response to the growth and identification of the logic of structural relations that underlie social institutions—whether they exist in terms of politics, economics, education, medicine, literature, or the sciences. Poststructuralism should therefore not be thought of as a distinct philosophy that exists separately as its own “structure”—a proposition that would undermine its most fundamental attitudes. Rather, post-structuralism should be thought of as developing or arising only in response to pre-existing structures and, as a set of attitudes, helping us better understand, interpret, and alter our social environment by calling established meanings into question, revealing the points of ambiguity and indeterminacy inherent in any system, rejecting the rationalistic piety that all systems are internally coherent and circle around an unchanging center, showing how discourses are carriers of power capable of turning us into subjects, and placing upon us the burden of ethical responsibility that accompanies the acceptance of freedom.

Although post-structuralism by its very nature as a set of attitudes denies any attempt at comprehensive definition, this essay examines three of the major postructuralist thinkers in order to relate their thought to the study of communication. First, following Derrida, post-structuralist thought invites a critical deconstruction of any discourse that presents itself as completely coherent, centered, and rational. Post-structuralist approaches thus do not argue against a position by harnessing counterarguments drawing on a different set of principles. Rather, it deconstructs a discourse by occupying it and exposing the gaps, contradictions, paradoxes, and deferments, thus revealing its established hierarchies, binaries, logical conclusions, and principles to be far more loosely structured and poly-vocal than its advocates wish to present them. Second, following Barthes, poststructuralism refuses to locate any single point of origin of any text that can ground its meaning—particularly by pointing to some ground of the author. Although not denying that writers exist, Barthes refuses to identify the meaning of a text with the author’s biography and intentions, instead inviting multiple interpretations from the perspective of individual readers who encounter the text as a unique event. Therefore, just as discourses do not have a unified structure, neither do individual texts or the authors that produce them. Lastly, following Fouacult, poststructuralism invites an inquiry into how discourses, texts, and acts of communication are always implicated in relations of power that act upon possible actions. Following the first two propositions, poststructuralism does not analyze these relations of power as completely structured and determinate, however. Power relations are always within a dynamic relationship with acts of resistance, thereby constantly leaving space for freedom and possibility.
Michael Hardt and Antonio Negri in Communication Studies
Authors: Bost Matthew , May Matthew S.
Published: May 2016

Michael Hardt and Antonio Negri are among the most powerful theorists of communication and social change under present-day global capitalism. In their Empire trilogy and other individual and collaborative works, Hardt and Negri argue for the fundamentally communicative nature of contemporary power. Their analyses demonstrate the ways that media technology, global flows of finance capital, and the contemporary shift to economies based on information and affective or emotional labor create new, more complex networks of oppression and new possibilities for more democratic social change. Hardt and Negri’s work, therefore, shifts the focus of critical communication and cultural theory from attaining or challenging political power within the nation-state and invites scholars to rethink sovereignty as empire: an interconnected global phenomenon appertaining to capitalism in the late 20th and early 21st centuries. They furthermore reimagine dissent as a constitutive process of resistance and mutual aid through which the multitude simultaneously withdraws from empire and composes itself through the social communication of struggles across time and space. Hardt and Negri’s work has been taken up in communication studies to theorize the materiality of communication; the labor performed in cognitive, communication, and service industries; contemporary media audiences and reception; and historical and contemporary social movements, from the Industrial Workers of the World to the Arab Spring and Occupy Wall Street.
Cultural Studies and Communication
Authors: Miller Toby
Published: May 2016

Communication and cultural studies share turbulent and contradictory histories, epistemologies, methods, and geographies, both on their own and as partners and rivals. This is in keeping with their status as interdisciplinary areas that emerged in the early to mid-20th century and crossed the humanities and the social sciences. Communication and cultural studies are linked and distinguished both by the topics they analyze and by their politics, countries, disciplines, theories, languages, and methods. Whereas the dominant forms of communication studies are dedicated to scholarly objectivity and disciplinary coherence, cultural studies is more akin to a tendency connected to concerns and identities on the margins of academia, and committed to methodological diversity. And whereas the critical strand of communication studies, notably political economy, examines such social forces of domination as the state and capital, cultural studies investigates the struggles undertaken by ordinary people to interpret dominant cultural forms in terms of their conditions of existence. The supposedly pessimistic orientation of political economy is frequently eschewed in favor of a faith in the resistive qualities of the oppressed and silenced. A similar perspective characterizes cultural studies’ rejection of effects studies for neglecting the politicized way that active audiences interpret media texts. In place of such concerns, the dominant strands of cultural studies tend to favor aesthetic and anthropological ways of analyzing societies to examine subjectivity and power and work with the understanding that popular culture represents and creates rituals and vice versa, through institutions and discourses that construct identities, which in turn form them.
Social Movement Participation and Climate Change
Authors: Goodman James
Published: May 2016

Climate change is often said to herald the anthropocene, where humans become active participants in the remaking of global geology. The corollary of the wide acceptance of a geological anthropocene is the emergence of a new form of self-aware climate agency. With awareness comes blame, invoking responsibility for action. What kind of social action arises from climate agency has become the critical question of our era. In the context of climate deterioration, the prevalence of inaction is itself an exercise of agency, creating in its path new fields of social struggle. The opening sphere of climate agency has the effect of subsuming other fields, reconfiguring established categories of human justice and ethical well-being. In this respect we can think of climate agency as having a distinctive, even revolutionary logic, which remains emergent, enveloping multiple aspects of social action.

From this perspective the question of climate change and social movement participation is centrally important. To what extent is something that we can characterize as “climate agency” emerging through social movement participation? What potential has this phenomenon to develop beyond ideological confinement and delimitation to make wider and transformative claims on society? A genuine social movement, we are taught from history, is indeed a transformative force capable of remaking social and political relations. It remains unclear, but what are the emergent dynamics of climate movement participation that depart from established systemic parameters, to offer such a challenge? How are such developments reconfiguring “climate change communication,” forcing an insurgent element into the polity?

Though scholarship addressing these questions on social movement participation and climate change exists, the field undoubtedly remains relatively underdeveloped. This reflects the extent to which inquiry into climate change has been dominated by scientific and economic discourses. It also reflects the difficulty that social science, and specifically political sociology, the “home” of social movement studies, has had in apprehending the scope of the challenge. Climate change can disrupt deeply sedimented assumptions about the relationship between social movements and capitalist modernity, and force a reconsideration of the role of social movements across developmentalist hierarchies. Such rethinking can be theoretically challenging, and force new approaches into view. These possibilities reflect the broader challenges to political culture posed by climate change.
Journalistic Depictions of Uncertainty about Climate Change
Authors: Painter James
Published: May 2016

Media research has historically concentrated on the many uncertainties in climate science either as a dominant discourse in media treatments measured by various forms of quantitative and qualitative content analysis or as the presence of skepticism, in its various manifestations, in political discourse and media coverage. More research is needed to assess the drivers of such skepticism in the media, the changing nature of skeptical discourse in some countries, and important country differences as to the prevalence of skepticism in political debate and media coverage. For example, why are challenges to mainstream climate science common in some Anglophone countries such as the United Kingdom, the United States, and Australia but not in other Western nations? As the revolution in news consumption via new players and platforms causes an increasingly fragmented media landscape, there are significant gaps in understanding where, why, and how skepticism appears. In particular, we do not know enough about the ways new media players depict the uncertainties around climate science and how this may differ from previous coverage in traditional and mainstream news media. We also do not know how their emphasis on visual content affects audience understanding of climate change.
Scientists’ Views about Public Engagement and Science Communication in the Context of Climate Change
Authors: Besley John , Dudo Anthony
Published: May 2016

Scientists who study issues such as climate change are often called on by both their colleagues and broader society to share what they know and why it matters. Many are willing to do so—and do it well—but others are either unwilling or may communicate without clear goals or in ways that may fail to achieve their goals. There are several central topics involved in the study of scientists as communicators. First, it is important to understand the evolving arguments behind why scientists are being called on to get involved in public engagement about contentious issues such as climate change. Second, it is also useful to consider the factors that social science suggests actually lead scientists to communicate about scientific issues. Last, it is important to consider what scientists are trying to achieve through their communication activities, and to consider to what extent we have evidence about whether scientists are achieving their desired goals.
