Resolving a gender and language problem in women’s leadership:consultancy research in workplace discourse

This article considers the contribution that consultancy research might make to resolving communication problems that women have identified in their leadership practices. Within the intersecting fields of gender and language and workplace discourse, consultancy research-that is, practitioner-commissioned research to resolve work-related, communication problems-is still uncommon. This article presents a study of Monika, a senior leader in an engineering company, who commissioned me to find out why she was experiencing communication problems with her teams. By using interactional sociolinguistic analysis, I was able to show Monika how her authority was being resisted on gendered, linguistic grounds. In making the case for more consultancy research, I discuss how we might use insights from discourse analysis to offer guidance to practitioners seeking our help

Navigating Immigration Law in a “Hostile Environment”: Implications for Adult Migrant Language Education

In this article the author analyses the communicative demands placed on migrants navigating immigration law in a fast‐moving policy environment and implications for adult migrant language education. Data are from an ethnographic study of a lawyer, Lucy, and her clients at a legal advice service in Leeds, England, and include interviews and recordings of lawyer–client interactions. The analytical focus is on Lucy’s stance (Jaffe, 2009b), on how she presents herself as an ally of her multilingual clients, and on the stance‐marking strategies she and her clients use as they strive to make meaning. The study took place in 2016, a time of volatility for the policies that impinge on immigration law and on legal interaction for migrants: the upsurge of right‐wing populist movements in Europe, erratic positions on migration in the United States, and the referendum that decided the United Kingdom would leave the European Union. The author maintains that the link is rarely drawn between interaction in legal and other institutional settings and the content of language classes designed to aid adult migrant settlement, and argues for an approach to adult migrant language education that critically addresses this point

Assumptions behind grammatical approaches to code-switching: when the blueprint is a red herring

Many of the so-called ‘grammars’ of code-switching are based on various underlying assumptions, e.g. that informal speech can be adequately or appropriately described in terms of ‘‘grammar’’; that deep, rather than surface, structures are involved in code-switching; that one ‘language’ is the ‘base’ or ‘matrix’; and that constraints derived from existing data are universal and predictive. We question these assumptions on several grounds. First, ‘grammar’ is arguably distinct from the processes driving speech production. Second, the role of grammar is mediated by the variable, poly-idiolectal repertoires of bilingual speakers. Third, in many instances of CS the notion of a ‘base’ system is either irrelevant, or fails to explain the facts. Fourth, sociolinguistic factors frequently override ‘grammatical’ factors, as evidence from the same language pairs in different settings has shown. No principles proposed to date account for all the facts, and it seems unlikely that ‘grammar’, as conventionally conceived, can provide definitive answers. We conclude that rather than seeking universal, predictive grammatical rules, research on CS should focus on the variability of bilingual grammars

Mice Engrafted with Human Fetal Thymic Tissue and Hematopoietic Stem Cells Develop Pathology Resembling Chronic Graft-versus-Host Disease

AbstractChronic graft-versus-host disease (cGVHD) is a significant roadblock to long-term hematopoietic stem cell (HSC) transplantation success. Effective treatments for cGVHD have been difficult to develop, in part because of a paucity of animal models that recapitulate the multiorgan pathologies observed in clinical cGVHD. Here we present an analysis of the pathology that occurs in immunodeficient mice engrafted with human fetal HSCs and implanted with fragments of human fetal thymus and liver. Starting at time points generally later than 100 days post-transplantation, the mice developed signs of illness, including multiorgan cellular infiltrates containing human T cells, B cells, and macrophages; fibrosis in sites such as lungs and liver; and thickened skin with alopecia. Experimental manipulations that delayed or reduced the efficiency of the HSC engraftment did not affect the timing or progression of disease manifestations, suggesting that pathology in this model is driven more by factors associated with the engrafted human thymic organoid. Disease progression was typically accompanied by extensive fibrosis and degradation of the thymic organoid, and there was an inverse correlation of disease severity with the frequency of FoxP3+ thymocytes. Hence, the human thymic tissue may contribute T cells with pathogenic potential, but the generation of regulatory T cells in the thymic organoid may help to control these cells before pathology resembling cGVHD eventually develops. This model thus provides a new system to investigate disease pathophysiology relating to human thymic events and to evaluate treatment strategies to combat multiorgan fibrotic pathology produced by human immune cells

E-Leadership or “How to Be Boss in Instant Messaging?” The Role of Nonverbal Communication

Doing leadership in the virtual realm has now become a routine part of many leaders’ daily work, yet our understanding of how leadership is enacted in mediated contexts—especially in text-only channels—is very limited. By applying micro-level analysis to naturally occurring instant message conversations, this article exposes the strategies leaders employ to achieve a range of complex communication goals: to get the work done while fostering informality and collegiality and creating the sense of a real—and not virtual—collaboration between team members. The findings further our understanding in two domains: They provide empirical grounding for e-leadership theories by exposing practices from real-life interactions, and they contribute to discursive leadership literature by addressing nonverbal communication practices. The findings of the article could form the basis for management and leadership training by drawing attention to the linguistic and semiotic resources digital leaders have at their disposal in virtual work environments

Identity work in different entrepreneurial settings:dominant interpretive repertoires and divergent striving agendas

This paper examines how entrepreneurs within different settings reflect on social interactions to work on their identity. Using life story narratives, we explore a business membership network and a creative hub in the central belt of Scotland. Our subsequent model shows how individuals in these settings use different dominant interpretive repertoires, as represented by structural-instrumental work in the business network and relational work in the creative hub. We also show how the interpretive repertoires both shape and are shaped by what individuals strive for in their identity work: striving for esteem and striving for closeness. We discuss how our findings offer insight into the dynamics of social identities and how they are reproduced and maintained through situated exchange using specific interpretive repertoires and striving agendas

An Epstein-Barr Virus (EBV) Mutant with Enhanced BZLF1 Expression Causes Lymphomas with Abortive Lytic EBV Infection in a Humanized Mouse Model

Immunosuppressed patients are at risk for developing Epstein-Barr Virus (EBV)-positive lymphomas that express the major EBV oncoprotein, LMP1. Although increasing evidence suggests that a small number of lytically infected cells may promote EBV-positive lymphomas, the impact of enhanced lytic gene expression on the ability of EBV to induce lymphomas is unclear. Here we have used immune-deficient mice, engrafted with human fetal hematopoietic stem cells and thymus and liver tissue, to compare lymphoma formation following infection with wild-type (WT) EBV versus infection with a “superlytic” (SL) mutant with enhanced BZLF1 (Z) expression. The same proportions (2/6) of the WT and SL virus-infected animals developed B-cell lymphomas by day 60 postinfection; the remainder of the animals had persistent tumor-free viral latency. In contrast, all WT and SL virus-infected animals treated with the OKT3 anti-CD3 antibody (which inhibits T-cell function) developed lymphomas by day 29. Lymphomas in OKT3-treated animals (in contrast to lymphomas in the untreated animals) contained many LMP1-expressing cells. The SL virus-infected lymphomas in both OKT3-treated and untreated animals contained many more Z-expressing cells (up to 30%) than the WT virus-infected lymphomas, but did not express late viral proteins and thus had an abortive lytic form of EBV infection. LMP1 and BMRF1 (an early lytic viral protein) were never coexpressed in the same cell, suggesting that LMP1 expression is incompatible with lytic viral reactivation. These results show that the SL mutant induces an “abortive” lytic infection in humanized mice that is compatible with continued cell growth and at least partially resistant to T-cell killing

Communicative competence and institutional affiliation: interactional processes of identity construction by immigrant students in Catalonia

The growing presence of children of immigrant families in the public school system in the bilingual region of Catalonia provides us with an opportunity to study how young multilingual and multicultural speakers construct their social competencies and their identity within the specific context of a gate-keeping social institution such as the school. The study reported in this paper approaches language learning as a process of socialisation that involves not only learning how to make sense of linguistic signs but also learning how to enact different social roles in particular institutions. The analysis focuses on the interactional profiles of two immigrant students in two types of communicative activities that are representative of the school context: responding to questions from an adult and cooperating with a peer in the resolution of a learning task. By shifting the focus of analysis from a decontextualised notion of communicative competence to the notion of 'institutionally affiliated communicative competence' and concentrating on issues such as the (1) the relationship between knowledge and participation, (2) language choice inside and outside school and (3) definitions of correctness in language use, the study reveals how the two students construct a highly 'affiliated' identit

Recognition of Lyso-Phospholipids by Human Natural Killer T Lymphocytes

Natural killer T (NKT) cells are a subset of T lymphocytes with potent immunoregulatory properties. Recognition of self-antigens presented by CD1d molecules is an important route of NKT cell activation; however, the molecular identity of specific autoantigens that stimulate human NKT cells remains unclear. Here, we have analyzed human NKT cell recognition of CD1d cellular ligands. The most clearly antigenic species was lyso-phosphatidylcholine (LPC). Diacylated phosphatidylcholine and lyso-phosphoglycerols differing in the chemistry of the head group stimulated only weak responses from human NKT cells. However, lyso-sphingomyelin, which shares the phosphocholine head group of LPC, also activated NKT cells. Antigen-presenting cells pulsed with LPC were capable of stimulating increased cytokine responses by NKT cell clones and by freshly isolated peripheral blood lymphocytes. These results demonstrate that human NKT cells recognize cholinated lyso-phospholipids as antigens presented by CD1d. Since these lyso-phospholipids serve as lipid messengers in normal physiological processes and are present at elevated levels during inflammatory responses, these findings point to a novel link between NKT cells and cellular signaling pathways that are associated with human disease pathophysiology.</p
