A team-learning framework for business model innovation in an emerging market

Abstract This study investigated how cross-functional teams can influence their business model innovation and firm performance through team learning, consisting of multiple modes of within-team, cross-team, and market learning. Using a matched dyadic data set from a study of 330 cross-functional team members and their supervisors sampled from 165 electronics and information industries in China, the empirical results clearly indicate that within-team, cross-team, and market learning can improve business model innovation and firm performance. The results of the mediating model show how the business model innovation mediates the relationship between team learning and firm performance.
The Influence of Being under the Influence

The authors examine the relationship between intoxication, chronic alcohol use, and violent behavior using data from the National Longitudinal Study of Adolescent Health. The authors introduce a method for disentangling spuriousness from the causal effects of situational variables. Their results suggest that drinkers are much more likely to commit violence while sober than non-drinkers, suggesting that a considerable portion of the relationship between prevalence of drinking and violence is spurious. The authors find evidence of a causal effect of intoxication, however, when they examine the relationship between frequency of drinking and violence while sober or drinking. Intoxication has stronger effects on adolescents who are older, White, and who already have violent tendencies.
Comparison of intravenous and subcutaneous exposure supporting dose selection of subcutaneous belimumab systemic lupus erythematosus Phase 3 program

Background Belimumab is a recombinant, human, IgG1λ monoclonal antibody that targets B-lymphocyte stimulator. The intravenous formulation is indicated for the treatment of active, autoantibody-positive systemic lupus erythematosus (SLE). Belimumab has been formulated for subcutaneous (SC) administration to improve patient convenience. This post-hoc modeling and simulation analysis characterizes the population pharmacokinetics (PK) of SC belimumab, and compares the exposure profiles of the approved belimumab IV dose—10 mg/kg every four weeks—to the 200 mg SC weekly dose in SLE patients, highlighting key pharmacological differences relevant for clinicians. Methods Data from two Phase 1 studies in US American and Japanese healthy subjects were analyzed with a non-linear mixed effects modeling approach. The resulting SC population PK model and a previously developed IV population PK model were used to conduct simulation trials in a Phase 3 IV belimumab SLE patient population, comparing chronic exposure profiles and exposure ranges stratified by body weight tertiles for IV vs SC dosing. Results The PK of belimumab following SC administration was best described by a linear two-comment model. The estimates for clearance, steady-state volume of distribution, and bioavailability were 208 mL/day, 5250 mL, and 76%, respectively. After four weeks of SC dosing, simulated belimumab concentrations exceeded the steady-state trough concentrations of the IV dosing regimen. At steady state simulated serum profiles demonstrated comparable average belimumab concentrations (Cavg,ss) after IV and SC dosing. Simulated belimumab exposures demonstrated largely overlapping concentration ranges following 200 mg SC weekly and 10 mg/kg IV every four weeks dosing. Discussion The predicted Cavg,ss of belimumab in SLE patients was comparable following 200 mg SC weekly and 10 mg/kg IV every four weeks dosing. The simulated belimumab accumulation following SC weekly dosing indicated that administration of a loading dose was not required. Similar Cavg,ss ranges were predicted for fixed dose SC and weight-proportional IV regimens in the simulated SLE population, albeit with a reversed body-size-to-exposure relationship for the SC regimen. These findings provide rheumatologists with a better understanding of expected differences in belimumab exposure when comparing IV and SC dosing regimens.
Physical-layer security over correlated erasure channels

Recent accomplishments in physical-layer security research have shown that channel coding for secrecy can be effectively combined with security at other layers, such as cryptography at the application layer, in order to provide a significant security enhancement to communication systems. The goal of this previous work was to inhibit the passive eavesdropper in the wiretap channel model by encoding the ciphertext using nonsystematic low-density parity-check (LDPC) codes prior to transmission and by exploiting the advantage of feedback for legitimate parties. The net result was propagation of a single packet erasure to the detriment of the entire message. The security enhancement was characterized assuming statistically independent packet erasure channels (PECs) for the legitimate receiver and the eavesdropper. In this paper, we go beyond these results by addressing correlated erasure events across the two channels in a wiretap feedback framework. The intuitive notion that high correlation across channels reduces secrecy is shown through the complete characterization of the correlated channel scenario. Furthermore, it is shown that security improvements are still achievable in the face of positive correlation by means of judicious physical-layer design, even when the eavesdropper has a better channel than the legitimate receiver.
Television Co-Viewing in Mexico: An Assessment on People Meter Data

Television co-viewing is a frequent behavior with important social and economic implications. This study proposes a measure of co-viewing on people meter panel data, tests it on a data set in Mexico, and uses it to explore co-viewing. Individual differences in psychographics, program genres and co-viewing of the lead-in programs were discovered as antecedents to co-viewing. Results indicate as well that co-viewing leads to increased watching time and reduced channel browsing, and this effect interacts with group composition. These findings provide further support for the social uses of television theoretical framework, and shed light on the inheritance effects in continuous programs.
Complaint stories revisited: the "masculine" performance of a "feminine" narrative genre in a conversation among Galician men

This article analyses and discusses excerpts from a friendly conversation among three Galician men in relation to broad characterisations of ‘feminine’ and ‘masculine’ interactional styles highlighted by more than two decades of sociolinguistic research on gender and discourse. In line with current tendencies in this area, it is assumed that these characterisations are ‘essentialist’, but it is also maintained that they capture quite well people’s dichotomous conceptions of gendered interactional styles, and that they use to function as an important guide for their behaviour in everyday social life. The main purpose of this article is precisely to illuminate the complex ways in which such conceptions proved as extremely opposing in the analysis of a ‘real’ conversation among men; specifically, the analysis offers empirical evidence that male participants in this speech event are expressing support and connection by collaboratively engaging in the practice of a ‘feminine’ narrative genre like complaint stories (Gunthner 1997a), though in an ‘acceptable’ way from the point of view of hegemonic masculinity; this is argued drawing on the fact that the topical focus of the talk is on football issues, and that the tellers do not take a vulnerable role but rather that of a highly indignant victim, as it is manifest in the ways the characters are portrayed and discussed, as well as in the construction of particularly ‘aggressive’ patterns of emotions display.
Autoconstruction in Working-Class Brazil

The ideologues of Brazil's industrialization have long advanced home ownership as a recipe for disciplining the work force. They argue that it brings social stability and moral development to the "dangerous classes. " Over the last 50 years, however, millions of workers have become home owners through a radicalizing process called autoconstruction (autoconstrucdo), in which they build their own houses in the urban hinterland under precarious material and legal circumstances. These conditions politicize them, becoming core issues of grassroots organizations and social movements. At the same time, autoconstruction is a domain of symbolic elaboration about the experience of becoming propertied and participating in mass consumer markets, in which both ruling-class and working-class ambitions for developing new social identities intersect. This elaboration occurs in the context of what is for most autoconstructors their greatest lifetime project: the transformation over decades of an initial shack of wood or concrete block into a dream house-a finished, furnished, and decorated masonry home.
Integrated care: meaning, logic, applications, and implications – a discussion paper

Abstract Integrated care is a burgeoning field. As is often the case in new areas of inquiry and action, conceptual clarification is demanded. Without such attention, it would be difficult to advance theory and practice in this increasingly important professional arena. In the following discussion paper, the authors explore the intellectual territory of integrated care, and underscore the need for a patient-centric imperative and meaning. They also examine the practical applications and implications arising from their views. The intention is to stimulate fruitful dialogue and debate about what ‘integrated care’ could and should be.
Asymmetry in task dependence among team members

Many of us spend a large part of our lives working in work teams, and our experiences in these teams can significantly influence our well-being, health and happiness (e.g., Sonnentag, 1996). As a result, gaining a deeper understanding of the organization and functioning of work teams is not just interesting, but could also lead to such desirable results as increased well-being or improved team performance (e.g., Ostroff, 1992). One of the more important theories that both practitioners and scholars use for understanding the functioning of work teams is inter-dependence theory (e.g., Thibaut & Kelley, 1959). This thesis aims to further the understanding of interdependence in work teams by investigating the role of differences or asymmetries in dependence between team members. These asymmetries in dependence occur when a team member (A) is more dependent on another team member (B) to complete his or her task, than B is dependent on A (e.g., Kelley & Thibaut, 1978). This vital element of interdependence has been largely overlooked in research so far, and in this thesis I aim to fill this gap in the interdependence literature.
Relationship between pre-service music teachers' personality and motivation for computer-assisted instruction

The main purpose of this study was to examine the relationship between pre-service music teachers' personalities and their motivation for computer-assisted music instruction (CAI). The ‘Big Five’ Model of Personality served as the framework. Participants were 83 pre-service music teachers in Turkey. Correlation analysis revealed that three dimensions of personality (Extroversion, Openness and Conscientiousness) were positively related to participants' motivation for CAI. Stepwise regression analysis revealed that only Extroversion and Openness dimensions made a significant contribution to the prediction of motivation. These results suggest that pre-service music teachers who see themselves as extroverted, sociable, organised, careful and disciplined tend to be more motivated to use CAI than those who see themselves as introverted, reserved, disorganised, careless and impulsive.
Taxonomic Composition and Trophic Structure of the Continental Bony Fish Assemblage from the Early Late Cretaceous of Southeastern Morocco

The mid-Cretaceous vertebrate assemblage from south-eastern Morocco is one of the most diversified continental vertebrate assemblages of this time worldwide. The bony fish component (coelacanths, lungfishes and ray-finned fishes) is represented by relatively complete specimens and, mostly, by fragmentary elements scattered along 250 kilometres of outcrops. Here we revisit the bony fish assemblage by studying both isolated remains collected during several fieldtrips and more complete material kept in public collections. The assemblage comprises several lungfish taxa, with the first mention of the occurrence of Arganodus tiguidiensis, and possibly two mawsoniid coelacanths. A large bichir cf. Bawitius, is recorded and corresponds to cranial elements initially referred to ‘Stromerichthys’ from coeval deposits in Egypt. The ginglymodians were diversified with a large ‘Lepidotes’ plus two obaichthyids and a gar. We confirm here that this gar belongs to a genus distinctive from Recent gars, contrary to what was suggested recently. Teleosteans comprise a poorly known ichthyodectiform, a notopterid, a probable osteoglossomorph and a large tselfatiiform, whose cranial anatomy is detailed. The body size and trophic level for each taxon are estimated on the basis of comparison with extant closely related taxa. We plotted the average body size versus average trophic level for the Kem Kem assemblage, together with extant marine and freshwater assemblages. The Kem Kem assemblage is characterized by taxa of proportionally large body size, and by a higher average trophic level than the trophic level of the extant compared freshwater ecosystems, but lower than for the extant marine ecosystems. These results should be regarded with caution because they rest on a reconstructed assemblage known mostly by fragmentary remains. They reinforce, however, the ecological oddities already noticed for this mid-Cretaceous vertebrate ecosystem in North Africa.
Refocusing or Recycling? The Stereotype Inoculation Model and Its Relationship With Research on Ingroup Role Models

Women have long been underrepresented in science, technology, engineering, and mathematics (STEM) fields (e.g., Ceci & Williams, 2010; Hill, Corbett, & St. Rose, 2010). Although there are many explanations for the lack of women in STEM (e.g., parental expectations and socialization to a lack of interest; Fredricks & Eccles, 2002; Frome & Eccles, 1998; Lapan, Adams, Turner, & Hinkelman, 2000), other research suggests that the negative stereotypes associated with women’s abilities in STEM-related fields, such as math, may also be a key factor (Inzlicht & Ben-Zeev, 2000; Schmader, 2002; Spencer, Steele, & Quinn, 1999). Indeed, this work highlights how subtle cues in the situation remind women of their stereotyped identity, harming their performance and consequently reinforcing the perception of group-based differences in ability (Steele, Spencer, & Aronson, 2002). Not surprisingly, considerable research attention has been paid to developing interventions against the adverse effects of these ability-based stereotypes. It is in this spirit that Nilanjana Dasgupta (this issue) proposes her stereotype inoculation model (SIM). The model, as Dasgupta notes, “shows how ingroup members (experts and peers in high-achievement settings) function as ‘social vaccines’ who inoculate and strengthen fellow group members’ self-concept so that they become free to choose less traveled paths” (p. 232). What we appreciate about the SIM is that it is part of a growing area of research that focuses on how ingroup role models disarm the negative effects of ability-based stereotypes (see, e.g., Marx, Ko, & Friedman, 2009; Marx & Roman, 2002; Marx, Stapel, & Muller, 2005; McIntyre, Paulson, & Lord, 2003). The appeal of using counterstereotypic ingroup role models as an intervention against such stereotypes is that, unlike other interventions, the role model approach does not rely on eliminating the stereotype from the situation or require women to distance themselves from their threatened identity, both of which may be impractical and/or difficult to implement in real-world contexts. Consequently, exposing women to ingroup role models appears to be a promising and relatively feasible approach to increasing their involvement and success in STEM. What we are less enthusiastic about are some of the premises underlying the SIM. First, we feel that it is an overstatement to claim that the SIM provides a “new theoretical lens. ” Yes, the SIM explores variables often not examined in prior role model work, but does this in and of itself constitute a new lens? Second, the SIM presents ingroup peers and experts as two distinct situational factors that can increase women’s self-concept and sense of belonging in STEM, yet they appear to us as a single factor that falls along the gender continuum. Third, we struggled with the rather sweeping assumption that women with low selfefficacy can still perform well. We would argue that this assumption holds only under specific conditions. In what follows we elaborate on each of these points.
Regulation of a Type III and a Putative Secretion System in Edwardsiella tarda by EsrC Is under the Control of a Two-Component System, EsrA-EsrB

ABSTRACT Edwardsiella tarda is a gram-negative enteric pathogen that causes hemorrhagic septicemia in fish and gastro- and extraintestinal infections in humans. A type III secretion system (TTSS) and a putative secretion system (EVP) have been found to play important roles in E. tarda pathogenesis. Our previous studies suggested that the TTSS and EVP gene clusters were regulated by a two-component system of EsrA-EsrB. In the present study, we characterized another regulator, EsrC, which showed significant sequence similarity to the AraC family of transcriptional regulators. Mutants with in-frame deletions of esrC increased the 50% lethal doses in blue gourami fish, reduced extracellular protein production, and failed to aggregate. Complementation of esrC restored these three phenotypes. Two-dimensional gel electrophoresis showed that EsrC regulated the expression of secreted proteins encoded by the TTSS (such as EseB and EseD) and EVP (EvpC) gene clusters. The expression of esrC required a functional two-component system of EsrA-EsrB. EsrC in turn regulated the expression of selected genes encoded in TTSS (such as the transcriptional unit of orf29and orf30, but not esaC) and genes encoded in the EVP gene cluster. The present study sheds light on the regulation of these two key virulence-associated secretion systems and provides greater insight into the pathogenic mechanisms of this bacterium.
Maturation of the auditory change detection response in infants: a longitudinal ERP study

Mismatch negativity (MMN) is a negative component of auditory event-related potential (ERP), reflecting the brain's automatic change detection process. In the present study we investigated the development of the pitch change detection, as indexed by the MMN, in the same infants from birth until 12 months of age. The MMN was identified in ∼75% of infants at each age, being relatively stable in latency and amplitude at the group level across the ages studied. However, within the same subjects the MMN substantially varied from age to age. The inspection of individual data revealed a possible source of this variability: in a portion of 3- to 9-month-old infants, a large-amplitude positive component commenced at the latency of the MMN and thus might have masked it. The results of the additional experiment, employing distracting novel sounds in 2-year-old infants and newborns, suggested that the observed positive component could represent an infant analogue of the adult P3a response, indexing an involuntary orienting of attention. Therefore, the variability from age to age might be, at least partially, caused by the differences in degree of infants' orienting, resulting in the reduction of the scalp recorded mismatch negativity in recordings when the orienting P3a positivity was elicited.
Women’s career advancement: mentoring and networking in Saudi Arabia and the UK

This study focused on women managers’ perceptions of mentoring and networking with respect to their career development in Saudi Arabia (SA) and the UK. This qualitative study used interviews to generate data, and we interviewed 44 women working as managers in public sector organizations in SA and the UK. The findings revealed that women in SA and the UK have different concepts of both mentoring and networking, and this relates to the cultures in the two countries. Women in SA associated mentoring and networking with their family members rather than their professional networks. In contrast, the women in the UK conceptualized mentoring and networking as something that took place, either formally or informally, in the workplace or through their wider professional networks. Both groups of women experienced challenges in their careers and received different forms of support from their professional groups and family members. Our comparative study provides a novel insight into women’s experiences from two very different perspectives and cultures; this will contribute to research and practice in this area. In particular, the findings illustrate the importance for human resource practitioners and talent managers of understanding the cultural context of their management and leadership development interventions. The paper concludes with an agenda for further research and also identifies the implications for human resource development practitioners which include adapting their strategies and practices to enable organizations to gain full value from their talent pool and realize women’s potential to hold top positions.
Diagenesis of Metals Chemically Complexed to Bacteria: Laboratory Formation of Metal Phosphates, Sulfides, and Organic Condensates in Artificial Sediments

Cells of Bacillus subtilis, when suspended in a 5mM metal solution, bind metals tenaciously to their cell walls. These metal-loaded cells, when mixed with a synthetic sediment and put under laboratory conditions to simulate low-temperature sediment diagenesis, nucleate the formation of a mixed assemblage of crystalline metal phosphates, metal sulfides, and polymeric, metal-complexed, organic residues. The sequential series of diagenetic events leading to the formation of authigenic mineral phases was followed by transmission electron microscopy and energy-dispersive X-ray analysis. The minerals quartz (SiO2) and calcite (CaCO3) were employed in the synthetic sediment. Crystalline magnetite (Fe2O3) and elemental sulfur were added as redox buffering agents to ensure anoxic conditions. Quartz and magnetite appeared unreactive throughout the experimental conditions. Elemental sulfur interacted with the metal-loaded cells, affected both the eventual chemistry and crystal habit of the metal phosphates, and formed a variety of crystalline metal sulfides. Calcite raised the pH of the fluid phase of the sediment, which influenced phosphate mineralization and inhibited metal sulfide genesis.
