Abstract
Purpose
Nutrition plays a key role in the recovery of pediatric trauma patients. A catabolic state in trauma patients may hinder recovery and inadequate nutrition may increase morbidity, mortality and length of hospital stay. The purpose of this paper is to review the current nutrition support practices for pediatric trauma patients at McMaster Children’s Hospital (MCH), describe patient demographics and identify areas to improve the quality of patient care.
Design/methodology/approach
A retrospective chart review was conducted on pediatric trauma patients (age<18 years) identified through the trauma registry of MCH. Pediatric trauma patients admitted from January 2010 to March 2014 with an Injury Severity Score (ISS)=12 and a hospitalization of =24 hours were included.
Findings
In total, 130 patients were included in this study, 61.1 percent male, median age ten years (range: 0-17 years) and median ISS of 17 (range: 12-50). Blunt trauma accounted for 97.7 percent of patients admitted and 73.3 percent had trauma team activation. In total, 93 patients (71.5 percent) had ICU stays. The median time to feed was 29 hours (interquartile range: 12.5-43 hours) from the time of admission. An increased hospital length of stay was associated with longer time to initiation of nutrition support, a higher ISS and greater number of surgeries (p<0.05).
Originality/value
Local nutritional support practices for pediatric trauma patients correspond with recommended principles of early feeding and preferential enteral nutrition. Harmonization of paper-based and electronic data collection is recommended to ensure that prescribed nutritional support is being delivered and nutritional needs of pediatric trauma patients are being met.

Abstract
Purpose
This study aims to develop an architectural prototype of a Cyber-Physical System (CPS), as well as lay a technological foundation for future smart housing with improved health and well-being outcomes for its occupants.
Design/methodology/approach
This study deploys smart sensors to monitor the key environmental parameters of a house. Using Internet of Things technology, a prototype of a CPS has been developed for capturing the environmental conditions over time. A case study involving a property in New Zealand was undertaken to validate the prototype.
Findings
The study proposes a monitoring platform, enabled by the CPS and smart sensing devices, that collects, shares, stores, analyses and visualises indoor environment data. The reliability and accuracy of the monitoring system were enhanced by comparing the activity of house occupants with sensor data.
Research limitations/implications
Due to limited time, the prototype was tested in one house for a period of one month. Air quality was not considered in this study. However, the work suggests that such an approach provides an effective solution for government organisations and housing agencies to collect information for the purpose of assessing building thermal performance.
Originality/value
This research proposes a new lens consisting of a home environment monitoring application with health and well-being implications. It could also be used to inform the future design of healthy homes and buildings, both in New Zealand and internationally.

Abstract
Purpose
The disparities of COVID-19 vaccination rates between the rural and urban areas have become apparent during this pandemic. There is a need to understand the root causes of vaccine hesitancy demonstrated by the rural population to increase coverage and to contain the disease spread throughout the United States. This study aimed to explore other factors influencing vaccine hesitancy among rural dwellers besides the geography-related barriers such as poor health care access and individuals having no or suboptimal insurance coverage.
Methodology/Approach
By reviewing existing data and literature about vaccination, health literacy, and behaviors, and prevailing ideologies, we discuss the potential causes of vaccine hesitancy in rural areas that could create barriers for successful public health efforts related to vaccine coverage and provide suggestions to ameliorate the situation.
Findings
Geography-related barriers, health literacy, and preconceived notions are key determinants of adopting healthy behaviors and complying with public health authorities' recommendations among rural individuals during a public-health crisis. We argue that ideology, which is much deeper than preconception or misconception on vaccination, should be incorporated as a key factor to redefine the term “vulnerable populations” in public health research.
Research Limitations/Implications
The limitation of our study is that we have not found an effective way to encourage the populations who hold conservative religious and political ideologies to join the efforts for public health. Even though geography-related barriers may strongly impact the rural dwellers in achieving optimal health, the various forms of ideologies they have toward certain health behaviors cannot be discounted to understand and address vaccine-related disparities in rural areas. There is a need to redefine the term “vulnerable population” particularly as it relates to rural areas in the United States. During large-scale public health disasters, scholars and public health authorities should consider the ideologies of individuals, in addition to other factors such as race/ethnicity, area of residence (rural vs. urban), and socioeconomic factors influencing the existing vulnerabilities and health disparities.

Abstract
Purpose
Since the development of the COVID-19 vaccinations, questions surrounding race have been prominent in the literature on vaccine uptake. Early in the vaccine rollout, public health officials were concerned with the relatively lower rates of uptake among certain racial/ethnic minority groups. We suggest that this may also be patterned by racial/ethnic residential segregation, which previous work has demonstrated to be an important factor for both health and access to health care.
Methodology/Approach
In this study, we examine county-level vaccination rates, racial/ethnic composition, and residential segregation across the U.S. We compile data from several sources, including the American Community Survey (ACS) and Centers for Disease Control (CDC) measured at the county level.
Findings
We find that just looking at the associations between racial/ethnic composition and vaccination rates, both percent Black and percent White are significant and negative, meaning that higher percentages of these groups in a county are associated with lower vaccination rates, whereas the opposite is the case for percent Latino. When we factor in segregation, as measured by the index of dissimilarity, the patterns change somewhat. Dissimilarity itself was not significant in the models across all groups, but when interacted with race/ethnic composition, it moderates the association. For both percent Black and percent White, the interaction with the Black-White dissimilarity index is significant and negative, meaning that it deepens the negative association between composition and the vaccination rate.
Research limitations/implications
The analysis is only limited to county-level measures of racial/ethnic composition and vaccination rates, so we are unable to see at the individual-level who is getting vaccinated.
Originality/Value of Paper
We find that segregation moderates the association between racial/ethnic composition and vaccination rates, suggesting that local race relations in a county helps contextualize the compositional effects of race/ethnicity.

Abstract
Purpose
Across the United States (US), COVID-19 vaccination coverage was lower in rural counties compared to urban counties, exacerbating rural health inequities. While rural communities fall short of the public health goal to vaccinate all who are eligible, most rural residents have chosen to vaccinate for COVID-19. The aim of this study was to better understand rural New Mexicans' attitudes and beliefs about COVID-19 vaccines.
Methodology
We conducted and analyzed 51 in-depth, semi-structured interviews with adults living in rural New Mexican counties, covering a range of topics related to the pandemic, including vaccines. These interviews were conducted in the Summer of 2021 after the vaccines were widely available to all adults over the age of 18 and youth between the ages of 12–17, but not yet available for children under 12 years.
Findings
Two major perspectives were identified: (1) the idea that COVID-19 vaccinations are a tool that individuals can use to achieve freedom and protection and (2) the view which regarded vaccines as an infringement of personal rights and one's autonomy of health. For people who viewed the vaccine as a tool for freedom, several themes emerged, including (1) a preference for vaccine manufacturers, specifically a preference for Pfizer, and (2) frustrations related to vaccine access, specifically, older adults expressed frustrations with the difficulty of scheduling vaccination appointments. However, most participants felt as though they had enough vaccination resources. For people who viewed vaccines (and vaccine mandates) as limiting their freedom, additional themes emerged: (1) overarching distrust of government and the perception that vaccines were an extension of government and (2) distrust in the vaccines themselves, including a perceived lack of research on the vaccines and a perception that the vaccine was developed in too short of a period. Some of the people who hold these beliefs are also vaccinated. We draw from social psychology theories to better understand how people who hold a rural identity come to establish different beliefs and practices compared to larger metropolitan regions. While political identity is a contributor, of our participants, the group who were most likely to report not being vaccinated were the “independent” or “unaffiliated voters.” Our findings can help craft culturally responsive vaccine initiatives for rural communities.

Abstract
Artificial intelligence-related inventions raise complex questions of how to define the boundaries around patentable subject matter. In the United States, many claim that the recent doctrinal developments by the Supreme Court have led to incoherence and excessive uncertainty within the innovation community. In response, policymakers and stakeholders have suggested legislative amendments to address these concerns. We first review these developments, and subsequently use the patent examination record to empirically test the claims of increased uncertainty. We find that, although uncertainty did spike following the Supreme Court's holding in Alice, it quickly returned to levels comparable to its historic norm. This has implications both for those advocating for legislative changes to the law of eligible subject matter, as well as other jurisdictions considering adopting a test similar to that applied in Alice.

Abstract
Purpose
The purpose of this study is to explore the moderating effect of Confucian values and the mediating effect of relationship quality on the relationship between organizational justice and employee service orientation in the tourism and hospitality industry.
Design/methodology/approach
Structural equation modeling was applied to a sample of 421 responses in a questionnaire survey from employees of tourism and hospitality firms in mainland China.
Findings
Employee relationship quality fully mediated the relationship between organizational justice and service orientation. Confucian values negatively moderated the direct effect of organizational justice on employee relationship quality and the indirect effect of organizational justice on service orientation.
Practical implications
This study offers insights for hospitality managers how to improve employee service orientation and establish Confucian values in the practice of organizational justice. Tourism and hospitality organizations should equally treat all employees as internal customers and use distinct strategies to manage employees with high and low Confucian values in employee selection and management of training and development.
Originality/value
This study highlights the contributions of organizational justice and relationship quality to employee service orientation. It also demonstrates that Confucian values explain why many Chinese employees are less sensitive to low fairness: these values negatively moderate the organizational justice–relationship quality–service orientation relations. By linking organizational justice to relationship quality and employee service orientation, the findings enrich our understanding of the applications of internal marketing and social exchange theories under Confucian values.
