Abstract
Purpose
This paper aims to explore the impact of the data observation period on the computation of altmetric measures like velocity index (VI) and half-life. Furthermore, it also attempts to determine whether article-level computations are better than computations on the whole of the data for computing such measures.
Design/methodology/approach
The complete publication records for the year 2016 indexed in Web of Science and their altmetric data (original tweets) obtained from PlumX are obtained and analysed. The creation date of articles is taken from Crossref. Two time-dependent variables, namely, half-life and VI are computed. The altmetric measures are computed for all articles at different observation points, and by using whole group as well as article-level averaging.
Findings
The results show that use of longer observation period significantly changes the values of different altmetric measures computed. Furthermore, use of article-level delineation is advocated for computing different measures for a more accurate representation of the true values for the article distribution.
Research limitations/implications
The analytical results show that using different observation periods change the measured values of the time-related altmetric measures. It is suggested that longer observation period should be used for appropriate measurement of altmetric measures. Furthermore, the use of article-level delineation for computing the measures is advocated as a more accurate method to capture the true values of such measures.
Practical implications
The research work suggests that altmetric mentions accrue for a longer period than the commonly believed short life span and therefore the altmetric measurements should not be limited to observation of early accrued data only.
Social implications
The present study indicates that use of altmetric measures for research evaluation or other purposes should be based on data for a longer observation period and article-level delineation may be preferred. It contradicts the common belief that tweet accumulation about scholarly articles decay quickly.
Originality/value
Several studies have shown that altmetric data correlate well with citations and hence early altmetric counts can be used to predict future citations. Inspired by these findings, majority of such monitoring and measuring exercises have focused mainly on capturing immediate altmetric event data for articles just after the publication of the paper. This paper demonstrates the impact of the observation period and article-level aggregation on such computations and suggests to use a longer observation period and article-level delineation. To the best of the authors’ knowledge, this is the first such study of its kind and presents novel findings.

Abstract
Purpose
This study focused on identifying measurable constructs of a restorative classroom and appropriate metrics to measure those constructs through content validity analysis of a direct observation tool. The tool was designed to assess restorative practices implementation in the classroom in the context of professional development supporting teachers in a fundamental reorientation towards non-punitive discipline.
Design/methodology/approach
The authors administered a 30-item survey to a panel of 14 experts in restorative practices implementation in schools asking them to provide quantitative and qualitative feedback on the tool's content, metrics, and utility for building teachers' skill and confidence in promoting a restorative classroom. The authors calculated item-level content validity indices and scale-level content validity indices. To interpret findings, the authors applied acceptability criteria recommended in the literature. The authors used qualitative coding to analyze qualitative responses and contextualize quantitative findings.
Findings
Quantitative results indicated that the tool's structure and measures of teacher behavior were acceptable. The student behavior scale did not meet the acceptability criterion. Qualitative feedback indicated that observation and later co-reflection on teachers' use of specific restorative skills was deemed helpful to teacher implementation of restorative practices. Observations of student behaviors, however, needed to be broadened to emphasize student voice and agency and the quality of student interactions.
Originality/value
Novel approaches to measurement are needed to facilitate teacher implementation of restorative practices as schools adopt those practices to promote equitable student agency, engagement and belonging in a pivotal shift from existing punitive discipline systems.

Abstract
Purpose
This study aims to develop a self-reflection scale useful for teachers to improve their skills and to clarify the Japanese teachers’ characteristics during mathematics lesson observation (MLO). In MLO, it is important to understand the lesson plan in advance to clarify observation points, and we aim to develop a scale including these points.
Design/methodology/approach
Based on the pre-questionnaire survey, nine perspectives and two situations for MLO were extracted. From these, a questionnaire for MLO was created. The results obtained from 161 teachers were examined, and exploratory factor analysis was conducted. ANOVA was conducted to analyze the effect of differences across the duration of teaching experience on the identified factors.
Findings
We developed a self-reflection scale consisting of 14 items with three factors: [B1] focus on instructional techniques and evaluation, [B2] focus on proactive problem-solving lesson development and [B3] focus on the mathematical background of the learning content. While duration of teaching experience showed no effect, three factors of the self-reflection scale for MLO showed a significant effect. Further multiple comparisons revealed the degree of focus was [B2]>[B1]>[B3].
Originality/value
Teachers who use this developed scale may grasp the strengths and weaknesses of their own MLO, which leads to self-improvement. The perspectives emphasized in lesson observation are the same when creating lesson plans and implementing lessons, leading to lesson improvement. Furthermore, based on the characteristics of teachers revealed, new training programs regarding MLO can lead to higher-quality lesson studies.

Abstract
Purpose
This paper revolves around the central question: is it possible to do “proper ethnography” without complete participant observation? The authors draw upon a student's experiences of negotiating National Health Service (NHS) ethical approval requirements and access into the student's research field, a British NHS hospital and having to adapt data collection methods for the student's doctoral research. The authors examine some of the positional (insider/outsider, native gone academic), methodological (long-term/interrupted, overt/covert) and contextual challenges that threatened the student's ethnographic study.
Design/methodology/approach
The paper draws on reflexive vignettes written during the student's doctorate, capturing significant moments and issues within the student's research.
Findings
The authors highlight the temporal, practical, ethical and emotional challenges faced in attempting an ethnography of nursing culture within a highly regulated research environment. Having revealed the student's experience of researching this specific culture and finding ways to overcome these challenges, the authors conclude that the contemporary ethnographer needs to be increasingly flexible, opportunistic and somewhat covert.
Research limitations/implications
The authors argue that it is possible to do “proper” and “good” ethnography without complete participant observation – it is not the method, the observation, that is the essence of ethnography, but whether the researcher achieves real understanding through thick descriptions of the culture that explain “what is really going on here”.
Practical implications
The authors hope to assist doctoral students engage in “good” ethnographic research within (potentially) risk-averse host organisations, such as the NHS, whilst being located in neo-liberal performative academic organisations (Foster, 2017; McCann et al., 2020). The authors wish to contribute to the journal to ensure good ethnography is accessible and achievable to (particularly) doctoral researchers who have to navigate complex challenges exacerbated by pressures in both the host and home cultures. The authors wish to see doctoral researchers survive and thrive in producing good organisational ethnographies to ensure such research is published (Watson 2012), cognisant of the pressures and targets to publish in top-ranked journals (Jones et al. 2020).
Originality/value
Having identified key challenges, the authors demonstrate how these can be addressed to ensure ethnography remains accessible to and achievable for, doctoral researchers, particularly in healthcare organisations. The authors conclude that understanding can be attained in what they propose as a hybrid form of “propportune” ethnography that blends the aim of the essence of “proper” anthropological approaches with the “opportunism” of contemporary data collection solutions.

Abstract
Purpose
This study explored teachers' perceptions of a specific, collaborative peer observation structure, collegial visits, and collegial visits' connection to collective teacher efficacy (CTE). The research question was: how do teachers perceive collegial visits, particularly with respect to their influence on CTE?
Design/methodology/approach
Within this qualitative descriptive study, 13 K-12 educators from three northeastern USA schools (one urban high school and a suburban middle and elementary school) were interviewed individually and/or in a focus group.
Findings
Utilizing social cognitive theory as a framework for analysis, the authors found a theme of a shift from uninformed to informed perceptions of the collective. Results demonstrated that collegial visits foster positive CTE beliefs.
Practical implications
Since collegial visits were found to increase participants' CTE, a construct others have associated with increased student achievement, school leaders should consider implementing collegial visits as a professional learning structure in their schools after considering their specific context.
Originality/value
Though there has been recent scholarship connecting peer observations and CTE, there has been no research, to date, to examine the effect of the specific structure of collegial visits on CTE.

Abstract
Purpose
Pressures from non-profit sport organizations’ (NPSOs) external environment influence governance structures and processes. Thus, this study explores the impact of external factors on NPSO board decision making.
Design/methodology/approach
Using a sample of six NPSO boards (two national, four provincial/territorial), data were collected via 36 observations, 18 interviews, and over 900 documents. A thematic analysis was conducted via NVivo 12.
Findings
Results identified two external factors impacting NPSO board decision making: the sport system structure and general environment conditions. External factors impacted NPSO board decision making in terms of duration, flow, interaction, and scrutiny.
Originality/value
Results demonstrate the need for NPSO boards to engage in boundary-spanning activities whereby external information sources from stakeholders are incorporated to make informed decisions. Practically, NPSO boards should harness virtual meetings to continue their operations while incorporating risk management analyses to assess threats and opportunities.

Abstract
Purpose
Because of the various advantages of reinforcement learning (RL) mentioned above, this study uses RL to train unmanned aerial vehicles to perform two tasks: target search and cooperative obstacle avoidance.
Design/methodology/approach
This study draws inspiration from the recurrent state-space model and recurrent models (RPM) to propose a simpler yet highly effective model called the unmanned aerial vehicles prediction model (UAVPM). The main objective is to assist in training the UAV representation model with a recurrent neural network, using the soft actor-critic algorithm.
Findings
This study proposes a generalized actor-critic framework consisting of three modules: representation, policy and value. This architecture serves as the foundation for training UAVPM. This study proposes the UAVPM, which is designed to aid in training the recurrent representation using the transition model, reward recovery model and observation recovery model. Unlike traditional approaches reliant solely on reward signals, RPM incorporates temporal information. In addition, it allows the inclusion of extra knowledge or information from virtual training environments. This study designs UAV target search and UAV cooperative obstacle avoidance tasks. The algorithm outperforms baselines in these two environments.
Originality/value
It is important to note that UAVPM does not play a role in the inference phase. This means that the representation model and policy remain independent of UAVPM. Consequently, this study can introduce additional “cheating” information from virtual training environments to guide the UAV representation without concerns about its real-world existence. By leveraging historical information more effectively, this study enhances UAVs’ decision-making abilities, thus improving the performance of both tasks at hand.

Abstract
Purpose
In comparison to other industries, the construction industry is one of the most dangerous industries. Behavior-based safety (BBS) is a common and useful technique for risk indicator processing. Almost all studies are based on the BBS checklist, but very few of them focus on the increasing dangers faced by construction workers and the important factors that lead to accidents. This research represents a risk spatiotemporal analysis and visual tracking approach based on BBS and Building Information Modeling (BIM).
Design/methodology/approach
After the literature review, a BBS checklist was developed. Then a survey was conducted based on the BBS checklist and the temporal evolution of risks has been completed. After that, managing the risk with the automatic rule checking (ARC) system using BIM was conducted simultaneously to develop a framework by conducting a case study.
Findings
Based on the grey clustering analysis, this work provides a temporal evolution analysis approach for dynamic analyzing BBS risk. According to the grey relational analysis (GRA) data, the main key factor of risk was the missing guardrail/handrail system. After that, a case study was performed and the system automatically warn in the preconstruction phase that the barrier is missing as the system benefits.
Originality/value
A systematic framework has been provided for risk analysis through which high health and safety performance outcomes can be achieved on construction projects. This study will assist design engineers in addressing the potential danger to employees during the preconstruction stage and monitoring dynamic changes in risk on any construction site.

Abstract
Purpose
The authors examine whether limitations in Form 990 result in zero or understated fundraising and administrative expenses for organizations supported by related organizations. Form 990 does not consolidate financial information of legally separate related organizations, resulting in fundraising and administrative expenses being reported by supporting organizations but not by the supported organization.
Design/methodology/approach
The authors use the IRS Statistics of Income Sample Data Files and compare charities receiving support from related organizations (supported) to non-supported charities.
Findings
The authors find evidence that supported organizations are likely to report zero or understated fundraising expenses and zero administrative expenses. Those receiving related donations are more likely to have zero or understated fundraising expense while those receiving related compensation are more likely to have zero and understated fundraising and administrative expenses. The authors also find evidence that supported organizations receiving greater amounts of related donations and related compensation are also more likely to report zero and understated fundraising expenses as well as zero administrative expenses while greater amounts of related compensation are also associated with understated administrative expense.
Practical implications
Since donors and other stakeholders use Form 990 to evaluate nonprofits, its unconsolidated nature could result in a lack of comparability across organizations and misinformed resource allocation (e.g. donation) decisions. The results also have implications for researchers who use zero and understated fundraising and administrative expenses as proxies for low quality reporting or interpret them as data errors.
Originality/value
The paper examines the extent to which zero or understated fundraising expense reporting (i.e. the fundraising expense puzzle) is associated with supported organizations receiving financial support from related organizations. The authors also expand their examination to zero and understated administrative expenses.

Abstract
Purpose
The purpose of the study is to examine the impact of corporate reputation (hereafter CR) and the degree of economic development on firms’ cost of capital remains unresolved. This study addresses these issues.
Design/methodology/approach
Using a global sample across 20 countries, the study investigates the discrete and joint effects of CR and jurisdictional economic development on the cost of equity (COE) and cost of debt (COD) capital. The analysis encompasses a dual data set, comprising 1,308 observations for COE and 1,223 observations for COD, allowing for a comprehensive exploration of these dynamics.
Findings
The findings indicate that CR leads to a reduction in the cost of capital for reputable firms. Nevertheless, the extent of this decrease varies per type of capital and firm’s reputation level and is contingent upon the economic development level within the firm’s jurisdiction. Particularly noteworthy is the moderating effect of economic development on CR, which shows that COE capital tends to be lower for reputable firms operating in economically developed jurisdictions. Albeit, this is not the case for COD capital for reputable firms in similarly developed jurisdictions.
Practical implications
This study illustrates that effective CR management, aimed at reducing the cost of capital, necessitates a combination of the firm’s unique competitive advantage and the economic development context of its jurisdiction to truly achieve its intended goal.
Originality/value
To the best of the authors’ knowledge, this is the first global study to explore the impact of CR on both COE and COD capital. Furthermore, this study is primarily towards understanding the moderating role of economic development in the relationship between CR and cost of capital.
