Fake Conformal Symmetry in Conformal Cosmological Models

We examine the local conformal invariance (Weyl invariance) in tensor-scalar theories used in recently proposed conformal cosmological models. We show that the Noether currents associated with Weyl invariance in these theories vanish. We assert that the corresponding Weyl symmetry does not have any dynamical role.Comment: References updated, errors corrected, published in Phys. Rev. D. 4 pages, RevTeX, no figure

Autism Spectrum: The Impact of Colors and Symbols Have on Students Outcome

The purpose of this action research paper was to explore the effects of educational interventions using colors and symbols on orchestra members with Autism Spectrum Disorder. A fifth week action study was conducted using visual support for effective musical expression in an orchestra composed of members with autism and intellectual disabilities. The red glasses marked on the sheet music of the members should see the conductor and play according to conductor’s hand signals, and the number of times they could not play according to the conductor\u27s hand signals was checked every week for 5 weeks to collect and analyze data. The educational intervention using colors and symbols was effective for all members, but the difference in intervention effect was large for member with autism. Positive responses from parents and team members to educational interventions using colors and symbols in structured surveys suggest more use of visual aids. Future research will investigate the effect of educational interventions using various colors and symbols on the performance of orchestra members, and whether the use of visual tools is helpful for orchestra operation

Errors in inflectional morphemes as an index of linguistic competence of Korean Heritage language learners and American learners of Korean

This study examined the linguistic competence in Korean of Korean heritage language learners (HLLs), compared to English-speaking non-heritage language learners (NHLLs) of Korean. It is unclear and controversial as to whether heritage languages learners are exposed to early but are interrupted manifest as L1 competence or share more characteristics with development in L2/FL competence. However, a common misconception is that HLLs outperform NHLLs in overall language skills even though Korean HLLs in Korean as a Foreign Language (KFL) classes do not make better progress than NHLLs despite their comparatively stronger aural interpretive abilities. This study was designed to investigate whether HLLs have an advantage over NHLLs in learning distinctive parametric values in Korean language, through comparing occurrences and sources of grammatical errors exhibited by two groups taking university-level KFL classes. This study addresses Korean inflectional morphemes, with a focus on case and postposition markers and affixal connectives. Data was collected from error analysis (EA) of inflectional morpheme errors and its source on semi-guided and self-generated writing samples, and grammaticality judgment in a word completion (GJWC) test using the same inflectional morphemes used for the EA. Schlyter's Weak language (WL) as L2, Montrul's WL as L1, and the Missing Surface Inflection Hypothesis (MSIH) provided theoretical frameworks. The EA data was coded using the Systematic Analysis of Language Transcript program. The EA and GJWC data were analyzed using a 2-way ANOVA and, when there was a significant interaction effect between heritage status and language proficiency level, a 1-way ANOVA. This study's results confirmed Schlyter's hypothesis, but did not support Montrul's hypothesis from either the EA or GJWC. MSIH failed in explaining underlying linguistic competence of HLLs. Significantly higher error rates caused by omitting necessary subject and object markers among HLLs imply their Korean morphological data stays at the level of Korean child's morphology. Significantly higher error rates in instrument marker in the GJWC test by advanced level of HLLs imply impaired Korean morphology of HLLs. Linguistic variation is more prominent among HLL group. Findings are further discussed in relation to their theoretical, methodological, and pedagogical implications. Differentiated instructional and curricular approaches for HLL and NHLL groups are suggested

Standardizing the Term “Strategy” in Retail and Business Curriculum

Strategy is a key concept in retail and business education. Yet, this important term has evolved to include many definitions, which can create confusion in the classroom environment. This paper proposes a standardized use of the term “strategy” in retail and business classrooms. It suggests a focused definition of strategy as “the principle that guides and inspires an organization to achieve optimum and long-term business performance by obtaining and sustaining competitive advantages.” It also outlines the development and definitions of strategy and discusses issues and concerns regarding the various definitions of strategy in academia. The study supports the need for clarification and efforts to incorporate standardized language into retail and business classroom settings. Keywords: Business, Competitive advantage, Curriculum, Education, Pedagogy, Retail, Strategy, Tactics.

MODELING THE CONSUMER ACCEPTANCE OF RETAIL SERVICE ROBOTS

This study uses the Computers Are Social Actors (CASA) and domestication theories as the underlying framework of an acceptance model of retail service robots (RSRs). The model illustrates the relationships among facilitators, attitudes toward Human-Robot Interaction (HRI), anxiety toward robots, anticipated service quality, and the acceptance of RSRs. Specifically, the researcher investigates the extent to which the facilitators of usefulness, social capability, the appearance of RSRs, and the attitudes toward HRI affect acceptance and increase the anticipation of service quality. The researcher also tests the inhibiting role of pre-existing anxiety toward robots on the relationship between these facilitators and attitudes toward HRI. The study uses four methodological strategies: (1) incorporating a focus group and personal interviews, (2) using a presentation method of video clip stimuli, (3) empirical data collection and multigroup SEM analyses, and (4) applying three key product categories for the model’s generalization— fashion, technology (mobile phone), and food service (restaurant). The researcher conducts two pretests to check the survey items and to select the video clips. The researcher conducts the main test using an online survey of US consumer panelists (n = 1424) at a marketing agency. The results show that usefulness, social capability, and the appearance of a RSR positively influence the attitudes toward HRI. The attitudes toward HRI predict greater anticipation of service quality and the acceptance of the RSRs. The expected quality of service tends to enhance the acceptance. The relationship between social capability and attitudes toward HRI is weaker when the anxiety toward robots is higher. However, when the anxiety is higher, the relationship between appearance and the attitudes toward HRI is stronger than those with low anxiety. This study contributes to the literature on the CASA and domestication theories and to the human-computer interaction that involves robots or artificial intelligence. By considering social capability, humanness, intelligence, and the appearance of robots, this model of RSR acceptance can provide new insights into the psychological, social, and behavioral principles that guide the commercialization of robots. Further, this acceptance model could help retailers and marketers formulate strategies for effective HRI and RSR adoption in their businesses
