Study Design.
Retrospective cohort study.

Objective.
To investigate the incidence of and risk factors for segmental motor paralysis after anterior cervical spine surgery.

Summary of Background Data.
Segmental motor paralysis is a potential complication following both anterior and posterior cervical decompression procedures; however, previous studies investigating risk factors for segmental motor paralysis after anterior cervical spine surgery were limited by small sample sizes. Consequently, the exact pathogenesis and risk factors for this complication remain poorly understood, highlighting the need for larger-scale investigations focused exclusively on anterior cervical spine surgeries.

Materials and Methods.
We retrospectively reviewed the clinico-demographic and operative factors and postoperative outcomes of 1428 patients undergoing anterior cervical spine surgery at three spine centers in Japan. Postoperative segmental motor paralysis was defined as deterioration of upper extremity muscle strength by ≥1 grade; recovery was defined as a return to preoperative muscle strength levels. Univariate and multivariate analyses were performed to identify risk factors.

Results.
Ninety-nine patients (6.9%) developed segmental motor paralysis, mostly involving the C5 segment (81.8%), the incidence being highest in patients with ossification of the posterior longitudinal ligament (OPLL) and those undergoing anterior cervical corpectomy and fusion or hybrid fusion (discectomy + corpectomy). Older age, male sex, higher body mass index, OPLL, and cervical corpectomy were independent risk factors for paralysis, with these patients having significantly worse clinical outcomes at 1 year postoperatively. Most patients (74/99, 79.6%) regained preoperative muscle strength levels at a final follow-up.

Conclusion.
This study identified important clinico-demographic and operative risk factors for segmental motor paralysis after anterior cervical spine surgery. Patients undergoing corpectomy, with or without OPLL, were found to be at particularly high risk. While most patients recover well, worse outcomes with segmental motor paralysis highlight the importance of preventing this complication, particularly for OPLL patients and corpectomy procedures.

Purpose
The Area Deprivation Index (ADI) is a validated quantifiable measure of neighborhood disadvantage and social determinants of health (SDoH). Higher percentiles in ADI correlate with the most disadvantaged neighborhoods: lower income, lower education, and less access to transportation. Using ADI, we aimed to investigate the impact of SDoH on bilateral breast reduction (BBR) complication rates.

Methods
A retrospective study of BBR patients from 2015 to 2021 was conducted. Patient addresses were matched to ADI percentiles and grouped into most (top 80% ADI) and least disadvantaged. Multivariable regressions were used to compare postoperative treatment between groups and adjust for confounders.

Results
In total, 568 patients were analyzed and 47% were high ADI. Time-to-event analysis revealed a 155% (β = 2.55; CI, 1.87–3.48; P < 0.001) increase in time to presentation for treatment of wound-related complications among higher-deprivation patients compared to their lower-deprivation counterparts. This difference in time to presentation equated to approximately 3 days overall when comparing higher to lower deprivation patients; however, this difference between the groups increased to 12 days when comparing those who experienced wound-related complications beyond day 30.

Conclusions
High deprivation was associated with increased delays to treatment after complications. More research is needed to determine the factors that impact postoperative courses among high ADI patients.

AbstractThe central complex (CX) plays a key role in many higher-order functions of the insect brain including navigation and activity regulation. Genetic tools for manipulating individual cell types, and knowledge of what neurotransmitters and neuromodulators they express, will be required to gain mechanistic understanding of how these functions are implemented. We generated and characterized split-GAL4 driver lines that express in individual or small subsets of about half of CX cell types. We surveyed neuropeptide and neuropeptide receptor expression in the central brain using fluorescentin situhybridization. About half of the neuropeptides we examined were expressed in only a few cells, while the rest were expressed in dozens to hundreds of cells. Neuropeptide receptors were expressed more broadly and at lower levels. Using our GAL4 drivers to mark individual cell types, we found that 51 of the 85 CX cell types we examined expressed at least one neuropeptide and 21 expressed multiple neuropeptides. Surprisingly, all co-expressed a small neurotransmitter. Finally, we used our driver lines to identify CX cell types whose activation a)ects sleep, and identified other central brain cell types that link the circadian clock to the CX. The well-characterized genetic tools and information on neuropeptide and neurotransmitter expression we provide should enhance studies of the CX.

AbstractThe mycobacterial cytoskeletal protein Wag31 is necessary for maintaining cell shape and directing cellular growth and elongation. Wag31 has a characteristic N-terminal DivIVA-domain and a C-terminal coiled-coil domain. While the role of Wag31 in polar elongation is known, there is limited mechanistic insight on how it orchestrates growth and elongation. In this report, we delineate roles of the N- and C-terminal domains of Wag31 using genetics, state-of-the-art multi-omics, biochemical, and imaging approaches. We show that Wag31 predominantly interacts with several membrane-associated proteins involved in lipid metabolism, cell wall synthesis and division. Native levels of Wag31 are critical for the maintenance and distribution of membrane lipids. Both depletion and overexpression of Wag31 perturbs lipid homeostasis, leading to the formation of intracellular lipid inclusions (ILIs). Protein-lipid crosslinking and imaging studies reveal that purified Wag31 can bind and effectively tether Cardiolipin (CL)-containing liposomes. We further show that the tethering activity lies in the DivIVA-domain containing N-terminal of Wag31 while the C-terminal mediates protein-protein interactions of Wag31. Despite retaining its ability to interact with partner proteins, the DivIVA domain-deleted Wag31 mutant shows defects in liposome tetheringin vitroand non-polar localization of CLin vivo, which eventually causes lethality. Our study suggests that membrane tethering ‘licenses’ Wag31 to form scaffolds that help orchestrate protein-lipid and protein-protein interactions necessary for mycobacterial growth and survival.
Generalized Langevin dynamics for single beads in linear elastic networks
Authors: Shinkai Soya , Onami Shuichi , Miyaguchi Tomoshige 
Published: October 2024

We derive generalized Langevin equations (GLEs) for single beads in linear elastic networks. In particular, the derivations of the GLEs are conducted without employing normal modes, resulting in two distinct representations in terms of resistance and mobility kernels. The fluctuation-dissipation relations are also confirmed for both GLEs. Subsequently, we demonstrate that these two representations are interconnected via Laplace transforms. Furthermore, another GLE is derived by utilizing a projection operator method, and it is shown that the equation obtained through the projection scheme is consistent with the GLE with the resistance kernel. As simple examples, the general theory is applied to the Rouse model and the ring polymer, where the GLEs with the resistance and mobility kernels are explicitly derived for arbitrary positions of the tagged bead in these models. Finally, the GLE with the mobility kernel is also derived for the elastic network with hydrodynamic interactions under the pre-averaging approximation.

Published: October 2024

PurposeStudies show that apprenticeships can enhance skills development and economic growth. There is a paucity of academic literature concerning apprenticeship’s role in developing Nigerian construction artisans’ skills, especially regarding achieving Sustainable Development Goal 8 (Decent Work and Economic Growth). Thus, this study aims to appraise the role of apprenticeship in developing construction artisans’ skills and suggest measures to improve skills development for artisans’ on-the-job training mechanisms to achieve Goal 8.Design/methodology/approachGiven the unexplored nature of the problem, the study utilised face-to-face data collection via a qualitative research approach. It covered two major cities in Nigeria and achieved saturation at the 29th chosen interviewee. Also, the study adopted a thematic method to analyse the data from selected construction artisans, construction firm management staffers and consultant experts in skills matters.FindingsEnhancing skills development, replacing the ageing workforce through practical broad-based skills training, bridging skills gaps, enhancing work-integrated learning and economic upliftment emerged as apprenticeship’s role in developing artisans’ skills in the Nigerian built environment if well implemented. Apprenticeship to develop skills in the built environment is not without hindrances. The perceived 34 barriers were re-clustered into employee, employer and government-related. Findings show that achieving Goal 8 may be threatened if these hindrances are not mitigated. They suggest improving skills development for artisans’ on-the-job training mechanisms to achieve Goal 8.Originality/valueThis study demonstrates that apprenticeship’s role in developing construction artisans’ skills should be all-inclusive. Also, the three stakeholders must do more concerning training programmes to improve artisans’ skills development to achieve Goal 8.

Housing and social sustainability in Uganda; case of Pagirinya Refugee Settlement in Adjumani district
Authors: Elong Samuel , Mukwaya Paul Isolo , Aboda Caroline 
Published: October 2024

Purpose
This paper aims to respond to the need for “socially sustainable settlements for all” and the need for successful integration within the settlements through building strong social constructs among the settlers.

Design/methodology/approach
Mixed methods were used in this study. A sample size of 332 households in Pagirinya Refugee Settlement was used. The settlement is divided into six blocks, each block is subdivided into clusters. Each cluster comprises of 100 households. Due to variations in the number of households in each settlement block, the authors used a proportional sampling approach to determine the number of respondent households in each settlement block. Data was collected through questionnaires, interviews and focus group discussions. Chi-square and an interdependent multivariate statistical analysis were performed to establish the relationship between housing and social sustainability.

Findings
The study finds a significant relationship between housing and social sustainability when considered jointly on the variables of roofs of buildings and how often the refugee respondents meet with neighbours (p = 0.018) and when considered jointly on the variables of the width of access roads and how knowledgeable the refugee respondents are about their neighbours (p = 0.018). The study also finds a significant relationship between housing and social sustainability when considered jointly on the variables of the number of direct access roads to the households and the number of friends of the refugee respondents (p = 0.019).

Originality/value
With limited literature, this is a novel approach. To the best of the authors’ knowledge, no previous studies focused on the specifics of a building and analysed its relationship with the social dynamics, especially in settlement studies.
Exploring memorable experiences in luxury hotels
Authors: Murray Jessica C. , Harrington Robert J. , Chathoth Prakash K. , Khan M. Sajid 
Published: October 2024

Purpose
This study aims to explore memory-dominant logic (MDL) in the luxury hotel context to assess the flow of management experience decisions to memorable experiences, which lead to guest outcomes. While research into memorable experiences has gained traction, the theoretical underpinnings of what makes an experience memorable in a luxury hotel setting are not well documented.

Design/methodology/approach
A grounded theory, qualitative methodology was used to assess MDL value transformation. Inductive methods included conducting in-depth interviews with hotel managers and analyzing social media reviews for each hotel. Guest reviews served as an indicator of memory outcomes and the counterpoint to the managerial interviews, supporting or refuting interview findings.

Findings
Key dimensions emerged, emphasizing the importance of managerial inputs to experience design, service experience attributes and memorable experience creation, demonstrating a sequence of memory-based value creation and outcomes such as positive word of mouth/electronic word of mouth (WOM/eWOM). Sentiment analysis identified attributes that appear to be a “must-have” to avoid dissatisfaction, as well as areas at risk for negative memories. Dimensions were developed into a framework using themes derived from MDL value transformation, management and consumer inputs that influence memorable experience outcomes in this context.

Research limitations/implications
The study supported the MDL theoretical framework by illustrating the flow from managerial inputs to the service experience, to elements of experience co-creation, and through to the guests’ WOM/eWOM and experience memories. The findings highlighted the symbiotic relationship between firm culture and service experience design, providing guidance for managerial practice going forward.

Originality/value
This paper uncovers major themes and dimensions identified by guests and managers as necessary in creating memorable experiences in a luxury setting and develops a framework that serves as a foundation for further study, including anteceding factors and their impact on hedonic consumption across experience domains.
Capital structure of special-purpose governments
Authors: Eger III Robert J. , Hermis Judith M. 
Published: October 2024

PurposeThe paper examines whether special purpose governments follow the pecking order model when raising capital, replacing firm equity in the original model with local intergovernmental revenues. Special purpose governments are a relatively underexamined component of state and local governments, and their capital structure choices have important implications for America’s aggregate fiscal health. This paper seeks to illuminate special purpose governments’ choices among available forms of capital.Design/methodology/approachTo address our research inquiry regarding whether special-purpose governments adhere to the pecking order theory, we narrow our focus to a specific group of transit entities. Our investigation utilizes data sourced from two distinct repositories: the United States Census of Governments and the National Transit Database. To facilitate integration of these disparate datasets, we establish a correspondence between them using the Federal Information Processing Standard and the transit identification number. Initially, our analysis employs maximum likelihood estimation, comparing these estimates to those generated by a naïve model. Subsequently, we derive parameter estimates through the application of a bivariate probit model.FindingsThe paper supports the pecking order hypothesis where internal funds are consumed first, debt is consumed next and IGR is consumed last. The results are robust and are not influenced by simultaneity bias.Research limitations/implicationsThe paper uses transit special purpose governments as the special purpose government of interest. These transit special purpose governments have high fixed costs that may inform their capital structure decisions relative to non-transit special purpose governments. Additionally, transit special purpose governments often have a profit-maximizing objective that may not uniformly apply to other special purpose governments, such as school districts, who lack such an incentive.Practical implicationsOur research should grab the attention of state and local politicians, voters, policy experts and scholars. Special-purpose governments, a key part of our governmental system, are on the rise. Understanding them better can guide decision-making on how to allocate resources, set policies and plan strategically. This knowledge boosts financial reporting quality, transparency, accountability and public confidence. Journalists can leverage our findings to ensure accurate and thorough reporting, fostering accountability and trust. Additionally, debt markets and analysts can factor this information into their risk assessments.Originality/valueThe paper enhances our understanding of how special purpose governments interact with existing models of corporate finance when making capital structure decisions.
