The purpose of this study was constructed a behavioral observation scale for avoiding food waste from the point of view of Chinese cuisine, used as an evaluation tool to examine food waste in the process of food preparation for hospitality students in Taiwan.

The status of food handling in the preparation process was understood through a literature review and interviews. In addition, the indicators that may cause food waste behaviors were established, and the observation and self-evaluation scales of food waste behaviors in the preparation process were developed.

Avoiding water waste, removing excessive edible parts, avoiding waste on seasonings, avoiding cooking for too long and avoiding water stains in the cleaning process were considered by both the observers and the students as items for improvement in the cooking process. The results of this study will help in understanding the intervention in the teaching practice of avoiding students’ food waste behaviors.

This study can only be based on the test results of the current observation behaviors. Meanwhile, many factors need to be taken into consideration, such as the differences in the amount of knowledge students have about food waste, the differences in preparation techniques, and other different factors, which may lead to differences in the research results.

The behavioral observation and self-evaluation behavior scales of “exploring food waste behaviors in the preparation process” were developed and implemented for the current status. The differences between the results of the observation scale and the self-evaluation scale were compared. In addition, the behaviors that may cause students’ food waste were pointed out. Then, the direction of the teaching content was formulated, and the curriculum plan integrating the content of avoiding food waste into teaching was evaluated. Furthermore, the scales can be applied to kitchen staff handling food materials to understand the current situation of their food handling, which can be used as a driving tool for restaurants to reduce food waste.

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.

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.

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].

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.

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.

The paper draws on reflexive vignettes written during the student's doctorate, capturing significant moments and issues within the student's research.

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.

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”.

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).

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.

The paper aims to identify the effect of ignorance of correlatedness among process observations and to implement new sampling schemes; skip and mixed sampling, in order to reduce the effect of autocorrelation on process capability index (PCI) Cpm.

Autocorrelated observations are generated using autoregressive process of order two (AR (2)) using Monte Carlo simulations. The PCI is computed based on these observations assuming the independence. The skip and mixed sampling schemes are then used to form sub-groups among correlated observations. The PCI obtained using sub-groups from skip and mixed sampling schemes are assessed using sample mean and sample standard deviation.

The paper provides empirical insights into how the effect of autocorrelation decreases in the estimated value of PCI Cpm. The use of new sampling schemes, skip and mixed sampling, reduces the effect of autocorrelation on estimates of PCI Cpm.

This paper fulfills an identified need to study how to reduce the effect of autocorrelation on PCI Cpm.

This paper introduces a novel quality measure, the percent-within-distribution, or PWD, for acceptance and payment in a quality control/quality assurance (QC/QA) performance specification (PS).

The new quality measure takes any sample size or distribution and uses a Bayesian updating process to re-estimate parameters of a design distribution as sample observations are fed through the algorithm. This methodology can be employed in a wide range of applications, but the authors demonstrate the use of the measure for a QC/QA PS with upper and lower bounds on 28-day compressive strength of in-place concrete for bridge decks.

The authors demonstrate the use of this new quality measure to illustrate how it addresses the shortcomings of the percent-within-limits (PWL), which is the current industry standard quality measure. The authors then use the PWD to develop initial pay factors through simulation regimes. The PWD is shown to function better than the PWL with realistic sample lots simulated to represent a variety of industry responses to a new QC/QA PS.

The analytical contribution of this work is the introduction of the new quality measure. However, the practical and managerial contributions of this work are of equal significance.

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?

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

The authors use the IRS Statistics of Income Sample Data Files and compare charities receiving support from related organizations (supported) to non-supported charities.

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.

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.

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.

The purpose of this case study is to determine the effectiveness of the UDL academy in terms of the number of UDL techniques used by faculty after participating in the academy and surveys to explore faculty perceptions of UDL.

This quantitative case study utilized faculty surveys about the UDL academy, class observations and review of course syllabi to determine the effectiveness of the UDL academy and explore the experience of implementing UDL.

The UDL initiative has been a positive and effective experience. Broadly, faculty have had positive perceptions of UDL implementations based on faculty surveys. The effectiveness of the UDL academy was demonstrated by the number of UDL techniques used by faculty increased significantly for faculty that participated in the UDL academy. The control group of faculty members did not increase the number of UDL techniques used based on class observations and a review of course syllabi.

This research is from one librarian's perspective since the librarian led the UDL initiative and is the sole librarian with faculty status currently at the institution. As a proponent of UDL, the librarian's perspective may be biased. Librarians can implement UDL to reduce educational barriers and support student success. Additionally, librarians can offer support to faculty in learning about UDL by offering a similar UDL academy.

Most faculty were able to incorporate UDL elements into their courses and responded positively to the concept of integrating UDL in the classroom, feeling that it helped improve their teaching. These results demonstrate that faculty can integrate UDL into higher education to use effective teaching strategies after participating in a UDL academy.

This paper is an original work describing a campus UDL initiative from a librarian's perspective.
