Recent teacher evaluation reforms across the globe can improve student outcomes, though doing so depends on implementation by school leaders. This study aims to describe how teacher reports about classroom observation processes (TROPs) vary across within-teacher observations, teachers and schools and depend on contextual, teacher and school characteristics.

A researcher–practitioner partnership collected TROPs using surveys administered multiple times during one semester and linked results to Tennessee administrative data. Random effects quantify TROP variation within examined clusters and estimate relationships between TROPs and the examined characteristics.

Although observation processes are well implemented on average, TROPs vary considerably across teachers and observations within teachers over a short period. TROPs also depend on several examined characteristics, but not necessarily in ways predisposed toward teacher development.

The study extends the understanding of the degree and extent to which teacher evaluation implementation by school leaders varies. Leadership preparation programs and in-service support providers might use the evidence herein to improve the extent to which evaluation-related observation processes are implemented consistently and in ways supporting teacher development.

The purpose of this paper is to replicate prior findings on teacher-principal race congruence and teacher job satisfaction and extend the literature by investigating trends over time and if the relationship between race congruence and teacher job satisfaction differs by principal race and region.

The study sample comes from four waves of cross-sectional data, the nationally representative Schools and Staffing Survey, administered between 2000 and 2012. The analysis is conducted using ordinary least squares and school-year fixed effects with a comprehensive set of covariates.

The relationship between race congruence and teacher job satisfaction is attenuating over time and is likely explained by the lower job satisfaction of white teachers who work for black principals. Some evidence indicates teacher-principal race congruence has greater salience in the Southern region of the country. Find evidence that teachers with race-congruent principals report more workplace support than their non-race congruent colleagues.

Future studies should investigate why racial congruence has more salience in the Southern region of the country and for white teachers who work with black principals. At the same time, results indicate that teacher-principal race congruence might no longer be a determinant of teacher job satisfaction, although further studies should continue investigating this relationship.

Findings on the changing nature of the relationship between principal-teacher race congruence and teacher job satisfaction over time as well as the differing nature of race congruence in the Southern region of the country are both novel findings in the literature.

Recent teacher evaluation reforms around the globe substantially increased the number of teacher observations, consequently raising observers' (typically school administrators') observational loads. The purpose of this study is to examine associations between observational loads and school administrator turnover, reported time use and strain.

The study uses education administrative data from the state of Tennessee to examine the link between observational loads and school administrator outcomes of interest. The results present credible regression estimates that isolate variation in observational loads within schools over time and within observers over time.

The evidence suggests individual school administrators allocate a set amount of time to observations that is insensitive to observational load and seemingly assign observations to colleagues strategically. School administrator reports do not suggest observational loads are associated with negative unintended consequences on administrator strain or observer turnover.

The study contributes to the literature on teacher evaluation by shedding light on how the constraints posed by an evaluation system may affect the work of school administrators. It also extends the job demands-resources theory that describes worker responses to new job demands.

The objective of this study is to investigate how country risk, different political actions from the government and bureaucratic behavior influence the activities in industry supply chains (SCs) in emerging markets. The main objective of this study is to investigate the influence of these external stakeholders’ elements to the demand-side and supply-side drivers and barriers for improving competitiveness of Ready-Made Garment (RMG) industry in the way of analyzing supply chain. Considering the phenomenon of recent change in the RMG business environment and the competitiveness issues this study uses the principles of stakeholder and resource dependence theory and aims to find out some factors which influence to make an efficient supply chain for improving competitiveness. The RMG industry of Bangladesh is the case application of this study. Following a positivist paradigm, this study adopts a two phase sequential mixed-method research design consisting of qualitative and quantitative approaches. A tentative research model is developed first based on extensive literature review. Qualitative field study is then carried out to fine tune the initial research model. Findings from the qualitative method are also used to develop measures and instruments for the next phase of quantitative method. A survey is carried out with sample of top and middle level executives of different garment companies of Dhaka city in Bangladesh and the collected quantitative data are analyzed by partial least square-based structural equation modeling. The findings support eight hypotheses. From the analysis the external stakeholders’ elements like bureaucratic behavior and country risk have significant influence to the barriers. From the internal stakeholders’ point of view the manufacturers’ and buyers’ drivers have significant influence on the competitiveness. Therefore, stakeholders need to take proper action to reduce the barriers and increase the drivers, as the drivers have positive influence to improve competitiveness.

This study has both theoretical and practical contributions. This study represents an important contribution to the theory by integrating two theoretical perceptions to identify factors of the RMG industry’s SC that affect the competitiveness of the RMG industry. This research study contributes to the understanding of both external and internal stakeholders of national and international perspectives in the RMG (textile and clothing) business. It combines the insights of stakeholder and resource dependence theories along with the concept of the SC in improving effectiveness. In a practical sense, this study certainly contributes to the Bangladeshi RMG industry. In accordance with the desire of the RMG manufacturers, the research has shown that some influential constructs of the RMG industry’s SC affect the competitiveness of the RMG industry. The outcome of the study is useful for various stakeholders of the Bangladeshi RMG industry sector ranging from the government to various private organizations. The applications of this study are extendable through further adaptation in other industries and various geographic contexts.

This paper aims to formalize long-term trajectories of human civilization as a scientific and ethical field of study. The long-term trajectory of human civilization can be defined as the path that human civilization takes during the entire future time period in which human civilization could continue to exist.

This paper focuses on four types of trajectories: status quo trajectories, in which human civilization persists in a state broadly similar to its current state into the distant future; catastrophe trajectories, in which one or more events cause significant harm to human civilization; technological transformation trajectories, in which radical technological breakthroughs put human civilization on a fundamentally different course; and astronomical trajectories, in which human civilization expands beyond its home planet and into the accessible portions of the cosmos.

Status quo trajectories appear unlikely to persist into the distant future, especially in light of long-term astronomical processes. Several catastrophe, technological transformation and astronomical trajectories appear possible.

Some current actions may be able to affect the long-term trajectory. Whether these actions should be pursued depends on a mix of empirical and ethical factors. For some ethical frameworks, these actions may be especially important to pursue.

The burnout, stress, and work-life balance challenges faced by teachers have received renewed interest due to the myriad disruptions and changes to K-12 schooling brought about by the COVID-19 pandemic. Even prior to the pandemic, relatively little was known about teachers' time use outside of the classroom, the blurring of work and home boundaries, and how teachers compare to similar professionals in these regards. We use daily time-diary data from the American Time Use Survey (ATUS) for 3,168 teachers and 1,886 professionals in similarly prosocial occupations from 2003 to 2019 to examine occupational differences in time use. Compared to observationally similar non-teachers, teachers spend significantly more time volunteering at their workplace and completing work outside the workplace during the school year. On average, teachers spend 19 more minutes working outside of the workplace on weekdays than observably similar non-teachers and 38 more minutes on weekends. The weekend disparity is particularly large among secondary school teachers. This suggests that before the widespread switch to online and hybrid learning necessitated by the COVID-19 pandemic, teachers were already navigating blurrier work-life boundaries than their counterparts in similar professions. This has important implications for teacher turnover and for the effectiveness and wellness of teachers who remain in the profession.

Extant research posits that mergers and acquisition (M&As) do not create value. Still many firms adopt expansion strategies such as alliances, joint ventures (JVs), and M&As to grow and enhance their performance. Through performing a meta-analysis on 204 papers that assess the relationship between the three most prevalent expansion strategies formed by firms, alliances, JVs, and M&As and their different substantive and symbolic performance effects, this study contributes in two ways. First, it becomes clear that alliances and M&As enhance a firm’s substantive performance, while no positive performance effect is observed for JVs. In turn, all three expansion strategies boost a firm’s symbolic performance in terms of its legitimacy and status. Second, a distinction between their effects on a firm’s substantive performance in terms of their market-based and accounting-based performance shows that alliances and M&As both positively contribute to a firm’s accounting-based performance, while only the former spurs a firm’s market-based returns. This indicates that M&As have more long-term accounting-based performance effects compared to alliances and JVs, which suggests that in the long-term firms do best by expanding through M&As.

In order to overcome potential limitations in their own experience with a strategic action, firms will often outsource to expert firms that have greater experience with such actions. In this study, the authors contribute to theory on organizational experience and learning by examining an important but understudied type of experience – outsourced experience. The authors show whether, and under what conditions, such experience may be beneficial for focal firms. In the context of acquisitions, the authors find that outsourced acquisition experience brought to acquisition deals by advisors is typically assessed by markets to be detrimental but may become beneficial if such experience is specific to the acquirer’s context. Further, the authors find that acquirers’ own knowledge can signal that they are less reliant on advisor experience, thus mitigating its potentially harmful effects. Theoretical and practical implications of the results are discussed.

In this chapter, we theorize that metaperceptions (beliefs about how one is viewed by others) derived from social identity categories will influence intrapersonal processing and resultant member interaction patterns in diverse work groups. In turn, such patterns of interactions will affect the quality of emergent states within diverse groups, ultimately impacting group-level outcomes. We will extend previous work in this area by examining the formation, nature, and consequences of metaperceptions in workgroups within which individuals vary with regard to social identities. In addition, we will describe the implications of metaperceptions for the effective leadership of diverse groups.

Currently, there is a great demand for those food products that are easy to prepare or ready for direct consumption. Making pear fruit/juice available round the year is desirous owing to pears' high-nutritional value and specific pleasant taste. Pear is, however, a seasonal fruit and under ambient conditions has a limited shelf life rendering it available as fresh fruit for a specific period.

The study aimed to optimize the spray drying process parameters using response surface methodology for the development of pear juice powder. The process variables included the inlet air temperature of 140–210°C, maltodextrin levels of 4–25%, atomization speed of 11,400–28,000 rpm, feed flow rate of 180–630 mL/hr, and feed total soluble solids (TSS) of 13–30°Brix. The dependent responses were powder yield, solubility, antioxidant activity {% 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity}, dispersibility, hygroscopicity and particle density.

Among independent variables, inlet air temperature showed a predominant effect. The optimum processing conditions for the development of pear juice powder with optimum quality were 163.02°C inlet air temperature, 13.50% maltodextrin, 28,000 rpm atomization speed, 390.94 mL/h feed flow rate, and 25.5°Brix feed TSS. Under these optimum conditions, pear powder with desirable properties could be produced. The experimental and predicted values were found to be in agreement, indicating the suitability of the model in predicting optimizing responses of pear powder. Glass transition temperature of pear powder was found to be 36.60 ± 0.40°C, which is much higher than that of ambient temperature, suggesting better shelf stability.

The processing of pear fruit has resulted in the increased demand for pear juice powder in both domestic and international markets as a primer of new food products. The optimum conditions obtained in the current study could provide a new insight to the food industry in developing spray-dried pear powder of optimum quality. This can open up a new horizon in the field of food industry for the common masses of Jammu and Kashmir, India.
