Emotional labor among team members: do employees follow emotional display norms for teams, not for customers?
Emotional labor is typically conceptualized as a process in which individuals regulate their emotions in response to display rules. Most research on emotional labor has focused on the influence of display rules at individual-level perceptions but is rarely examined at the team level. We examine the influence of the shared display rules in teams as emotional display norms. This study considers emotional dissonance as the difference between the positive emotional display norm at the team level and positive emotion at the individual level. To examine the purpose of this study, data were collected from leader-follower pairs within teams and based on a three-wave design. Thus, this study conducted a multi-level polynomial regression analysis and used the response surface methodology to interpret the incongruence effect. The results show that the incongruence effect of emotional dissonance is positively related to surface acting. In addition, the moderating effect of regulatory focus significantly strengthens the positive relationship between emotional dissonance and emotion regulation strategies. The results also show that surface acting strategy is negatively related to selfless Organizational citizenship behaviors (OCB). These findings highlight that emotional display norms play an important role as the standard for emotional experience in teams, and especially with the moderating effect of self-regulatory focus, emotion regulation strategies affect the selfless OCB rating of observers
Dietary Glucose Consumption Promotes RALDH Activity in Small Intestinal CD103(+)CD11b(+) Dendritic Cells
Retinal dehydrogenase (RALDH) enzymatic activities catalyze the conversion of
vitamin A to its metabolite Retinoic acid (RA) in intestinal dendritic cells (DCs)
and promote immunological tolerance. However, precise understanding of the exogenous
factors that act as initial trigger of RALDH activity in these cells is still
evolving. By using germ-free (GF) mice raised on an antigen free (AF) elemental
diet, we find that certain components in diet are critically required to establish
optimal RALDH expression and activity, most prominently in small intestinal
CD103(+)CD11b(+) DCs (siLP-DCs) right from the beginning of their lives.
Surprisingly, systematic screens using modified diets devoid of individual dietary
components indicate that proteins, starch and minerals are dispensable for this
activity. On the other hand, in depth comparison between subtle differences in
dietary composition among different dietary regimes reveal that adequate glucose
concentration in diet is a critical determinant for establishing RALDH activity
specifically in siLP-DCs. Consequently, pre-treatment of siLP-DCs, and not
mesenteric lymph node derived MLNDCs with glucose, results in significant
enhancement in the in vitro generation of induced Regulatory T (iTreg) cells. Our
findings reveal previously underappreciated role of dietary glucose concentration in
establishing regulatory properties in intestinal DCs, thereby extending a potential
therapeutic module against intestinal inflammation11Ysciescopu

Examining augmented reality in middle schools through a review of studies on augmented reality in education
Although augmented reality (AR) is considered a promising technology in the field of education, many educators are still having trouble distinguishing between AR and virtual reality. Therefore, this report aims to present and refine the understanding of AR technology in middle school-level education based on existing studies published in the last three years. A total of eighteen academic journal articles were reviewed to obtain a comprehensive view of the definitions, types, features, advantages, limitations, and integration methods of AR in middle schools. According to Azuma (1997), AR is a technology that enhances one’s sense of reality by enabling the coexistence and simultaneous interaction of digital information and the real world. The most commonly used types of AR today are marker/vision-based and location-based. Based on the reviewed studies, eight features, five advantages, and six limitations of AR technology are identified. In addition, the ways in which AR technology has been integrated into middle school classrooms are described.Curriculum and Instructio

Volatile and Non-Volatile Allelopathic Characteristics in Thermally Processed Needles of Two Conifers
With allelopathic composts, potential merits for preventing initial weed infestations have been observed in crop transplantation. However, previous studies have rarely investigated whether high temperatures, generated during composting, decrease allelopathic ability. This study evaluated the thermal allelopathic effect of two coniferous plants (Pinus densiflora and P. koraiensis) on Brassica napus germination and seedling growth using their characterized allelochemical destinations. The 90 °C dry treatment of P. densiflora extract exhibited stronger inhibitory effect on germination than its 30 °C dry treatment. In a range from 0.25 to 1 mg mL−1, the germination rate was decreased to 38.1 and 64.3% of control with P. densiflora extract dried at 90 and 30 °C, respectively. However, P. koraiensis showed potent inhibition of the germination process with no statistical difference in inhibitory effects regardless of the dry temperature. Regarding B. napus seedling root growth, the allelopathic effects of aqueous extracts of both conifers were not reduced with the 90 °C treatment, but it was lost in seedling shoot growth. GC-MS/MS confirmed that high temperature treatment drastically decreased volatile contents to 53.2% in P. densiflora, resulting in reduced allelopathic abilities. However, a relatively lower decrease to 83.1% in volatiles of P. koraiensis accounts for less loss of the root-specific inhibitory effect on B. napus seedlings even after 90 °C treatment. Foliar tissues of both conifers with species-specific thermal resistance have potentially valuable functions regarding allelopathic use in horticultural compost processing ingredients, demonstrating their weed control ability during the early cultivation season where crops are transplanted in the facilitated area

Transcriptional Profiling Reveals Mesenchymal Subtypes of Small Cell Lung Cancer with Activation of the Epithelial-to-Mesenchymal Transition and Worse Clinical Outcomes
While molecular subtypes of small cell lung cancers (SCLC) based on neuroendocrine (NE) and non-NE transcriptional regulators have been established, the association between these molecular subtypes and recently recognized SCLC-inflamed (SCLC-I) tumors is less understood. In this study, we used gene expression profiles of SCLC primary tumors and cell lines to discover and characterize SCLC-M (mesenchymal) tumors distinct from SCLC-I tumors for molecular features, clinical outcomes, and cross-species developmental trajectories. SCLC-M tumors show elevated epithelial-to-mesenchymal transformation (EMT) and YAP1 activity but a low level of anticancer immune activity and worse clinical outcomes than SCLC-I tumors. The prevalence of SCLC-M tumors was 3.2–7.4% in primary SCLC cohorts, which was further confirmed by immunohistochemistry in an independent cohort. Deconvoluted gene expression of tumor epithelial cells showed that EMT and increased immune function are tumor-intrinsic characteristics of SCLC-M and SCLC-I subtypes, respectively. Cross-species analysis revealed that human primary SCLC tumors recapitulate the NE-to-non-NE progression murine model providing insight into the developmental relationships among SCLC subtypes, e.g., early NE (SCLC-A and -N)- vs. late non-NE tumors (SCLC-M and -P). Newly identified SCLC-M tumors are biologically and clinically distinct from SCLC-I tumors which should be taken into account for the diagnosis and treatment of the disease
