Energy appliance transformation in commercial buildings in India under alternate policy scenarios

Amit Garg, Jyoti Maheshwari, P.R.Shukla, and Rajan RawalKordrostami

Energy, 140(1), 952-965

The total electricity consumption from commercial sector was about 9% during 2013–14 in India. Load research survey was carried out to study the usage patterns for all types of electric appliances used in commercial establishments at income, appliance and end-use levels in Gujarat state of India – one of the most progressive states. Penetration level of efficient appliances, electricity load curves and Energy Performance Index (EPI) were estimated. The mean EPI was 98 kWh/m2/year (SD = 105.5) for surveyed small commercial establishments (low income) while mean EPI was 181 kWh/m2/year (SD = 68) for surveyed large commercial establishments (Malls). Electricity saving potentials was estimated if electric appliances at these commercial establishments were replaced with efficient appliances. Four alternate scenarios were analyzed using cost of conserved energy (CCE) curves with various efficiency enhancement options – following at least commercial sub-category level median EPIs, following average EU equivalent EPI levels, following average EPI levels of equivalent US commercial establishments, and following the best available technologies (BAT). The average energy savings ranged between 14% and 25% across buildings and scenarios. Energy efficient air-conditioner and LED lights offer the highest energy savings potential among appliances.

Normative underpinnings of direct employee participation studies and implications for developing ethical reflexivity: A multidisciplinary review

George Kandathil and Jerome Joseph

Journal of Business Ethics

This paper seeks to join studies which have drawn attention to the ethical reflexivity of research and the research enterprise in the organisational studies’ field. Towards this end, we review OB, HRM, and IR studies on direct employee participation in organisations post-1990s to examine their normative underpinnings. Using Fox’s (Industrial sociology and industrial relations. Research Paper 3, Royal Commission on Trade Unions and Employers’ Associations, HMSO, London, 1966, Beyond contract: Work, power and trust relations. Faber and Faber, London, 1974) three frames—unitarist, pluralist, and radical—we compare the underpinnings within and across the chosen disciplines to bring ethical reflexivity to studies in this area of inquiry. Implications are drawn out to take forward the quest for more ethically reflexive employee participation research.

Association of grade configuration with school climate for 7th and 8th grade students

Marisa Malone, Dewey Cornell, and Kathan Shukla

School Psychology Quarterly

Educational authorities have questioned whether middle schools provide the best school climate for 7th and 8th grade students, and proposed that other grade configurations such as K–8th grade schools may provide a better learning environment. The purpose of this study was to compare 7th and 8th grade students’ perceptions of 4 key features of school climate (disciplinary structure, student support, student engagement, and prevalence of teasing and bullying) in middle schools versus elementary or high schools. Multilevel multivariate modeling in a statewide sample of 39,036 7th and 8th grade students attending 418 schools revealed that students attending middle schools had a more negative perception of school climate than students in schools with other grade configurations. Seventh grade students placed in middle schools reported lower disciplinary structure and a higher prevalence of teasing and bullying in comparison to those in elementary schools. Eighth grade students in middle schools reported poorer disciplinary structure, lower student engagement, and a higher prevalence of teasing and bullying compared to those in high schools. These findings can guide school psychologists in identifying aspects of school climate that may be troublesome for 7th and 8th grade students in schools with different grade configurations.

Racial/ethnic differences in perceptions of school climate and its association with student engagement and peer aggression

Timothy Konold, Dewey Cornell, Kathan D. Shukla, and Francis Huang

Journal of Youth and Adolescence

Research indicates that a positive school climate is associated with higher levels of student engagement and lower rates of peer aggression. However, less attention has been given to whether such findings are consistent across racial/ethnic groups. The current study examined whether Black, Hispanic, and White high school students differed in their perceptions of school climate, student engagement, and peer aggression as measured by the Authoritative School Climate survey. In addition, the study tested whether the associations between school climate and both student engagement and peer aggression varied as a function of racial/ethnic group. The sample consisted of 48,027 students in grades 9–12 (51.4 % female; 17.9 % Black, 10.5 % Hispanic, 56.7 % White, and 14.9 % other) attending 323 high schools. Regression models that contrasted racial/ethnic groups controlled for the nesting of students within schools and used student covariates of parent education, student gender, and percentage of schoolmates sharing the same race/ethnicity, as well as school covariates of school size and school percentage of students eligible for free- or reduced-price meals. Perceptions of school climate differed between Black and White groups, but not between Hispanic and White groups. However, race/ethnicity did not moderate the associations between school climate and either engagement or peer aggression. Although correlational and cross-sectional in nature, these results are consistent with the conclusion that a positive school climate holds similar benefits of promoting student engagement and reducing victimization experiences across Black, Hispanic, and White groups.

A two-step latent profile method for identifying invalid respondents in self-reported survey data

Kathan D. Shukla and Timothy Konold

Journal of Experimental Education

Insincere respondents can have an adverse impact on the validity of substantive inferences arising from self-administered questionnaires (SAQs). The current study introduces a new method for identifying potentially invalid respondents from their atypical response patterns. The two-step procedure involves generating a response inconsistency (RI) score for each participant and scale on the SAQ and subjecting the resulting scores to latent profile analysis to identify classes of atypical RI respondent profiles. The procedure can be implemented post–data collection and is illustrated through a survey of school climate that was administered to N = 52,102 high school students. Results of this screening procedure revealed high levels of specificity and expected levels of concordance when contrasted with the results of traditionally used methods of screening items and response time. Contrasts between valid and invalid respondents revealed similar patterns across the three screening procedures when compared across external measures of academics and risk behaviors.

Does school climate mean the same thing in the United States as in Mexico? A focus on measurement invariance

Kathan D. Shukla, Tracy E. Waasdorp, Sarah Lindstrom Johnson, Mercedes Gabriela Orozco Solis, Amanda J. Nguyen, Cecilia Colunga Rodríguez, and Catherine P. Bradshaw

Journal of Psychoeducational Assessment

School climate is an important construct for guiding violence prevention efforts in U.S. schools, but there has been less consideration of this concept in its neighboring country Mexico, which has a higher prevalence of violence. The U.S. Department of Education outlined a three-domain conceptualization of school climate (i.e., safe and supportive schools model) that includes engagement, safety, and the school environment. To examine the applicability of this school climate model in Mexico, the present study tested its measurement invariance across middle school students in the United States (n = 15,099) and Mexico (n = 2,211). Findings supported full invariance for engagement and modified-safety scales indicating that factor loadings and intercepts contributed almost equally to factor means, and scale scores were comparable across groups. Partial invariance was found for the environment scales. Results of a multigroup confirmatory factor analysis (MGCFA) consisting of all 13 school climate scales indicated significantly positive associations among all scales in the U.S. sample and among most scales in the Mexico sample. Implications of these findings are discussed.

Institutional discourses and ascribed disability identities

Mukta Kulkarni, K.V.Gopakumar, and Devi Vijay

IIMB Management Review,

In the present study we asked: how do institutional discourses, as represented in mass media such as newspapers, confer identities upon a traditionally marginalised collective such as those with a disability? To answer our question, we examined Indian newspaper discourse from 2001 to 2010, the time period between two census counts. We observed that disability identities—that of a welfare recipient, a collective with human rights, a collective that is vulnerable, and that engages in miscreancy—were ascribed through selective highlighting of certain aspects of the collective, thereby socially positioning the collective, and through the associated signalling of institutional subject positions. Present observations indicate that identities of a collective can be governed by institutional discourse, that those “labelled” can themselves reinforce institutionally ascribed identities, and that as institutional discourses confer identities onto the marginalised, they simultaneously also signal who the relatively more powerful institutional actors are.

Survey on revenue management in media and broadcasting

Shinjini Pandey, Goutam Dutta, and Harit Joshi

Informs Journal on Applied Analytics

Advertisements are a key source of revenue for companies in the broadcasting and web industries. However, because of increasing competition, advertisers and web publishers have been forced to find innovative ways to increase their profits and gain competitive advantages. Revenue management is a useful operations research and management science tool that may be used to do so. In this paper, we provide an updated review of revenue-management research conducted in the broadcasting and online advertisement industries, highlighting the strategies and techniques adopted to maximize advertising revenue. We also identify mobile advertising as an emerging revenue-management application and review current research on it. We conclude by identifying potential gaps that future research might address.

A system dynamics simulation model of a blast furnace for project evaluation

Goutam Dutta and Medha Ashtekar

International Journal of Business and Systems Research

The manufacturing of hot metal in a blast furnace is one of the important parts of an integrated steel plant. In a blast furnace, the quality and productivity of the output (hot metal) depends on a large number of input and operating variables. In this paper, we simulate complex interactions of technological and financial variables. We chose system dynamics principles to simulate the blast furnace for project evaluation as a useful aid to managerial decisions. The model would be used to answer a number of questions related to investment decisions. We simulate the actual production of hot metal, accumulated hot metal production, net works cost and cost of hot metal per ton for a period of 36 months with real data.

An orchestrated negotiated exchange: Trading home-based telework for intensified work

George Mathew Kandathil and Dharma Raju Bathini

Journal of Business Ethics

In this paper, we explore a popular flexible work arrangement (FWA), home-based telework, in the Indian IT industry. We show how IT managers used the dominant meanings of telework to portray telework as an employee benefit that outweighed the attendant cost—intensified work. While using their discretion to grant telework, the managers drew on this portrayal to orchestrate a negotiated exchange with their subordinates. Consequently, the employees consented to accomplish the intensified work at home in exchange of telework despite their opposition to the intensified work in the office. Thus, whereas the extant studies consider work intensification as an unanticipated outcome of using FWAs, we show how firms may use FWAs strategically to get office-based intensified work accomplished at home. While the dominant argument is that employees reciprocate the opportunity to telework with intensified work, we show a discursively orchestrated negotiation that favors management. A corrective policy measure is to frame telework as an employee right.
