Abstract We revisit the relation between the anomalies in four and six dimensions and the Chern-Simons couplings one dimension below. While the dimensional reduction of chiral theories is well-understood, the question which three and five-dimensional theories can come from a general circle reduction, and are hence liftable, is more subtle. We argue that existence of an anomaly cancellation mechanism is a necessary condition for liftability. In addition, the anomaly cancellation and the CS couplings in six and five dimensions respectively determine the central charges of string-like BPS objects that cannot be consistently decoupled from gravity, a.k.a. supergravity strings. Following the completeness conjecture and requiring that their worldsheet theory is unitary imposes bounds on the admissible theories. We argue that for the anomaly-free six-dimensional theories it is more advantageous to study the unitarity constraints obtained after reduction to five dimensions. In general these are slightly more stringent and can be cast in a more geometric form, highly reminiscent of the Kodaira positivity condition (KPC). Indeed, for the F-theoretic models which have an underlying Calabi-Yau threefold these can be directly compared. The unitarity constraints (UC) are in general weaker than KPC, and maybe useful in understanding the consistent models without F-theoretic realisation. We catalogue the cases when UC is more restrictive than KPC, hinting at more refined hidden structure in elliptic Calabi-Yau threefolds with certain singularity structure.

The paper aims to empirically explore the impact of six dimensions of workplace spirituality on three types of organizational commitment. Six dimensions of workplace spirituality used for the study are Swadharma, Lokasangraha, authenticity, sense of community, Karma capital and Krityagyata. Components of organizational commitment are affective, normative and continuance commitment. A sample of 541 employees working in various organizations was given a structured questionnaire. Correlations, regressions and Necessary Condition Analysis(NCA) were carried out. The paper has enriched the field of workplace spirituality by contributing to existing literature via adding one more construct of Indian spirituality i.e. Krityagyata. Paper concludes that workplace spirituality climate helps in promoting organizational commitment. NCA elicited necessity of various dimensions of workplace spirituality for healthy organizational commitment.

Employee Experience

The COVID-19 crisis has drawn broader public interest in how companies treat their workers, so going forward, people management would be of an increasing concern. As we make a transition from a service-based economy to experience economy, where time well saved takes a back seat to time well spent, the notion of employee experience (EX) is set to become a fundamental workplace design principle. EX is about the work, not the office. EX aims for a complete redesign of the workplace practices and environment to fit the employees and not the other way around. This article examines and verifies EX scale as one-dimensional as well as multidimensional constructs with six dimensions, namely cohesiveness, vigour, well-being, achievement, inclusiveness and physical environment. Six dimensions were explored with focus group and open-ended survey and validated with closed-ended survey of 299 employees working in multinational corporations across India. Structural equation modelling is used to validate the proposed latest construct. Establishing the EX scale would help researchers as well practitioners in empirically measuring EX and its relationship with various individuals as well organizational constructs.

Abstract Background Paying more attention to free-roaming dogs’ population control seems to be necessary because of public health and environmental problems. The present study used the community readiness model to determine the readiness of Aradan County in terms of collecting stray dogs. Methods This study is a quantitative-qualitative research study conducted in Aradan County in Semnan Province of Iran. The semi-structured questionnaire uses the six dimensions of the Community Readiness Model as guideline, with 36 items used for the interview. The interviews lasted 45 to 100 minutes with 11 key members including the governor, prefect, mayor’s assistant, city council chairman, key trustees, officials responsible for environmental health network, officials responsible for environmentalism of the city, and governors of a rural district. In quantitative part two, assessors read the interviews carefully and assigned scores based on the rating-scale form suggested by the guideline itself for scoring each dimension. A qualitative directed content analysis with deductive approach was used for analyzing the collected qualitative data. Results The study involved 11 key members of Aradan County, all of whom were male. Most of the participants were over 40 years old and with five years of work experience (73.6 %). The mean score of each six dimensions in Aradan County were: Community efforts (4.78), Community knowledge of efforts (4.28), Leadership (4.90), Community climate (4.38), Community knowledge about the issue (4.20) and Resources related to the issue (3.29) respectively. Community readiness in Aradan County and Aradan City was generally estimated to be in the preplanning stage, whereas vague public awareness was found in the rural areas. In the qualitative part, 870 initial open codes, 589 refund codes, 19 subcategories and 6 themes emerged, including (a) community efforts, (b) community knowledge of the efforts (c) leadership, (d) community climate, (e) community knowledge of the issue, and (f) resources related to the issue. Conclusions For improving the process of collecting the stray dogs, it is necessary to focus on holding educational sessions for the public to increase their partnership and justify the responsible organizations’ activities to collaborate and provide the necessary financial resources.

Abstract Background Despite the high burden of disease in younger children there are few tools specifically designed to estimate Health Related Quality of Life (HRQoL) in children younger than 3 years of age. A previous paper described the process of identifying a pool of items which might be suitable for measuring HRQoL of children aged 0–3 years. The current paper describes how the items were pruned and the final draft of the measure, Toddler and Infant (TANDI) Health Related Quality of Life, was tested for validity and reliability. Methods A sample of 187 caregivers of children 1–36 months of age were recruited which included children who were either acutely ill (AI), chronically ill (CI) or from the general school going population (GP). The TANDI, an experimental version of the EQ-5D-Y proxy, included six dimensions with three levels of report and general health measured on a Visual Analogue Scale (VAS) from 0 to 100. The content validity had been established during the development of the instrument. The TANDI, Ages and Stages Questionnaire (ASQ), Faces, Leg, Activity, Cry, Consolabilty (FLACC) or Neonatal Infant Pain Scale (NIPS) and a self-designed dietary information questionnaire were administered at baseline. The TANDI was administered 1 week later in GP children to establish test-retest reliability. The distribution of dimension scores, Cronbach’s alpha, rotated varimax factor analysis, Spearman’s Rho Correlation, the intraclass correlation coefficient, Pearson’s correlation, analysis of variance and regression analysis were used to explore the reliability, and validity of the TANDI. Results Concurrent validity of the different dimensions was tested between the TANDI and other instruments. The Spearman’s Rho coefficients were significant and moderate to strong for dimensions of activity and participation and significant and weak for items of body functions. Known groups were compared and children with acute illness had the lowest ranked VAS (median 60, range 0–100), indicating worse HRQoL. The six dimensions of the TANDI were tested for internal consistency and reliability and the Cronbach’s α as 0.83. Test-retest results showed no variance for dimension scores of movement and play, and high agreement for pain (83%), relationships (87%), communication (83%) and eating (74%). The scores were highly correlated for the VAS (ICC = 0.76; p < 0.001). Conclusion The TANDI was found to be valid and reliable for use with children aged 1–36 months in South Africa. It is recommended that the TANDI be included in future research to further investigate HRQoL and the impact of interventions in this vulnerable age group. It is further recommended that future testing be done to assess the feasibility, clinical utility, and cross-cultural validity of the measure and to include international input in further development.

Gauge Anomaly

Abstract The conditions for the absence of gauge anomalies in effective field theories (EFT) are rivisited. General results from the cohomology of the BRST operator do not prevent potential anomalies arising from the non-renormalizable sector, when the gauge group is not semi-simple, like in the Standard Model EFT (SMEFT). By considering a simple explicit model that mimics the SMEFT properties, we compute the anomaly in the regularized theory, including a complete set of dimension six operators. We show that the dependence of the anomaly on the non-renormalizable part can be removed by adding a local counterterm to the theory. As a result the condition for gauge anomaly cancellation is completely controlled by the charge assignment of the fermion sector, as in the renormalizable theory.
