ABSTRACT
Ecologists have long been interested in relevant techniques to track the field movement patterns of fish. The elemental composition of otoliths represents a permanent record of the growing habitats experienced by a fish throughout its lifetime and is increasingly used in the literature. The lack of a predictive and mechanistic understanding of the individual kinematics underlying ion incorporation/depletion limits our fine-scale temporal interpretation of the chemical signal recorded in the otolith. In particular, the rate at which elements are incorporated into otoliths is hypothesized to depend on fish physiology. However, to date, time lags have mostly been quantified on a population scale. Here, we report results from controlled experiments (translocation and artificially enriched environment) on individual trace element incorporation/depletion rates in Salmo trutta (Salmonidae). We reported significant lags (i.e. weeks to months) between changes in water chemistry and the subsequent change in otolith composition and highlighted substantial inter-individual variations in the timing and magnitude of Sr/Ca and Ba/Ca responses. These differences are partially linked to the energetic status (i.e. metabolic rate) of the individuals. It therefore appears that individuals with the highest metabolic rate are more likely to record detailed (i.e. brief) temporal changes than individuals having lower metabolic values. The time taken for environmental changes to be reflected in the growing otolith thus can no longer be assumed to remain a constant within populations. Results from the current study are a step towards the fine reconstruction of environmental histories in dynamic environments.

Background: In the consumer-centric global economy of the 21st century, customer retention is a vital concept in the hospitality industry for building and sustaining long-term relationships. Recognizing the challenges of acquiring new customers, the industry acknowledges the significance of retaining existing ones. To achieve their goals, hospitality businesses need a comprehensive strategy that extends beyond price targets, emphasizing the development of effective pricing strategies from the outset. Methods: Data collection took place between June 2022 and January 2023, involving a random sample of seven international hotels located in Tirana, Durres, and Vlora. Quantitative data was collected through surveys utilizing Likert-scale questions. Statistical analysis, including crosstab tests, was employed to explore the relationship between economy pricing strategies and customer retention. Results: The study encompassed 572 participants representing diverse demographic characteristics. Analysis revealed a statistically significant positive relationship between economy pricing strategies and customer retention in international hotels in Albania. These findings underscore the importance of implementing effective pricing strategies to enhance customer loyalty and guide the development of improved strategies within the hotel industry. Conclusions: This study provides empirical evidence of a significant positive relationship between economy pricing strategies and customer retention in international hotels in Albania. Effective pricing strategies play a crucial role in fostering customer loyalty. However, the study's limitations, primarily its focus on specific hotels in Albania, call for further research to validate the generalizability of these findings. The insights gained from this study inform policymakers and industry stakeholders in formulating strategies to enhance customer retention within the hospitality sector.

Published: June 2023

Purpose: Dietary intake assessment has an essential role in chronic disease studies and general public health outcomes. To measure dietary intakes in epidemiologic studies, various dietary assessment methods are used. Among them, food frequency questionnaires (FFQs) can provide useful measures of dietary intake. This study aimed to report the development of a population-specific dish-based food frequency questionnaire (DFQ) to assess long-term usual dietary intakes in Afghanistan. Design/Methodology/Approach: We considered the Willet format and followed these steps; listing commonly consumed Afghani foods, determining food groups, defining portion sizes, and determining the frequency response options for each food item. We prepared a comprehensive list of foods and dishes commonly used in Afghanistan. We categorized dishes and food items in the questionnaire into eight major groups. Portion sizes for food items and mixed dishes were defined based on the most commonly consumed and understandable portion sizes for each item among the Afghan general population. The frequency response options for each food item were defined separately in a row against the food list. Findings: We developed a new population-specific DFQ in Afghanistan containing 103 food items or dishes, which can be used as an instrument for the assessment of long-term dietary intakes as well as diet-disease associations in Afghanistan. Originality/Value: This is the first ever-developed dietary assessment tool in Afghanistan.

Background: In the United States, patients with limited English proficiency face significant barriers to comprehending and acting upon health-related information, particularly during the COVID-19 pandemic. The ability of health professionals to communicate COVID-19-related information to Mandarin-speaking patients has proved critical in discussions about vaccine efficacy, side effects, and post-vaccine protection. Methods: The authors created a one-hour educational module to help Mandarin-speaking medical students better convey COVID-19 vaccine information to Mandarin-only speakers. The module is composed of an educational guide, which introduced key terminology and addressed commonly asked questions, and pre- and post-surveys. The authors recruited 59 Mandarin-speaking medical students all of whom had previously completed a medical Mandarin elective. The module and surveys were distributed and completed in August 2021. Data analysis measured the change in aggregate mean for subjective five-point Likert-scale questions and change in percent accuracy for objective knowledge-based questions. Results: 86.4% of participants were primary English speakers with variable levels of Mandarin proficiency. The educational module significantly improved participants' subjective comfort level in discussing the COVID-19 vaccine in English and Mandarin. The largest improvement in both English and Mandarin was demonstrated in participants' ability to explain differences between the COVID-19 vaccines, with an aggregate mean improvement of 0.39 for English and 1.48 for Mandarin. Survey respondents also demonstrated increased percent accuracy in knowledge-based objective questions in Mandarin. Conclusions: This module provides Mandarin-learning medical students with skills to deliver reliable information to the general population and acts as a model for the continued development of educational modules for multilingual medical professionals.

Hub Network Design Problem with Capacity, Congestion, and Stochastic Demand Considerations
Authors: Bayram Vedat , Yıldız Barış , Farham M. Saleh 
Published: June 2023

Our study introduces the hub network design problem with congestion, capacity, and stochastic demand considerations (HNDC), which generalizes the classical hub location problem in several directions. In particular, we extend state-of-the-art by integrating capacity acquisition decisions and congestion cost effect into the problem and allowing dynamic routing for origin-destination (OD) pairs. Connecting strategic and operational level decisions, HNDC jointly decides hub locations and capacity acquisitions by considering the expected routing and congestion costs. A path-based mixed-integer second-order cone programming (SOCP) formulation of the HNDC is proposed. We exploit SOCP duality results and propose an exact algorithm based on Benders decomposition and column generation to solve this challenging problem. We use a specific characterization of the capacity-feasible solutions to speed up the solution procedure and develop an efficient branch-and-cut algorithm to solve the master problem. We conduct extensive computational experiments to test the proposed approach’s performance and derive managerial insights based on realistic problem instances adapted from the literature. In particular, we found that including hub congestion costs, accounting for the uncertainty in demand, and whether the underlying network is complete or incomplete have a significant impact on hub network design and the resulting performance of the system.

Published: June 2023

The greenhouse gas monitoring instruments were carried on the
Gaofen-5-II satellite, which was launched into orbit from the Taiyuan
Satellite Launch Center on September 7, 2021. In order to improve the
on-orbit data quantification level, a calibration device based on
diffuse reflector system was designed, which can realize on-orbit
spectral and radiation calibration. In this paper, the principle of
standard spectral line selection is given, and the characteristic
spectral lines that can be used for on-orbit spectral calibration are
extracted. The wavelength deviation evaluation function is established
by using the method of matching the high-resolution reference spectrum
after the linear function of the convolution instrument with the
on-orbit calibration measurement spectrum, and finally using the
Levenberg–Marquardt algorithm to evaluate the function. The
optimization solution is the on-orbit wavelength calibration result.
According to the above method, the on-orbit calibration data are
processed. After calibration, the maximum deviation of the on-orbit
spectral offset is changed from 0.133 to 0.009cm−1, and variations in magnitude less
than 10% of the spectral resolution for CO2 (1.57 µm) band have
been detected.

Published: June 2023

New technological advancements and solutions should be investigated to overcome the stringent performance and societal requirements that 6G networks will pose in terms of capacity scaling, performance, efficiency, and sustainability. In this regard, the design and implementation of modular, scalable, cost-effective, and programmable transceiver architectures are key towards meeting future 6G network targets. In this paper, multiband (MB) sliceable bandwidth/bitrate variable transceivers with advanced capabilities are proposed and experimentally assessed, enabling full reconfigurability, sliceability, and scalability following a pay-as-you grow approach. Different transceiver building blocks will be enabled/disabled and will operate within different spectral bands beyond the C-band, according to the network condition. The proposed architecture enables point-to-point and point-to-multipoint operation maximizing the network’s resiliency, efficiency, and sustainability. 60 Gb/s MB transmission (C + S) is demonstrated over a metro-regional aggregation network path of 25.2 km. Scalability towards multi-Tb/s transmission is envisioned by exploiting the whole available spectral bands.

In the realm of consumer electronics, automotive, and robotics, lidar has proven to be a valuable technology. However, current lidar solutions such as mechanical, microelectromechanical, and flash lidar are associated with drawbacks such as high cost, low resolution, and a limited ranging distance. To address these issues, optical phased array (OPA) technology has been proposed as a promising solution due to its high resolution, rapid response times, long ranging distance, and low cost. Despite these advantages, OPA is still in the developmental stages and further optimization is required to address issues such as loss, field of view (FOV), and beam divergence. To address the FOV and beam divergence issues, SiN-assisted grating antenna has been used. However, the directionality of an SiN-assisted antenna is relatively low and may introduce additional loss for OPA. To overcome this limitation, this paper proposes a dual-layer SiN-assisted grating antenna with more than 94% directionality in 1550 nm. Moreover, the wavelength bandwidth of more than 90% directionality is over 80 nm, making it a promising solution for OPA devices.

Lasers at ∼900nm have been of vital importance in various fields, including material processing, underwater communications, and strong-field physics. Although Nd3+-doped materials have been employed for the ∼900nm laser, the ∼900nm emission is in strong competition with the often more dominating ∼1060nm emission, which strongly limits the output power and applications. This paper proposes a direct coordination engineering approach, which introduces halogen to the nearest coordination of Nd3+ in glass for increasing the bond covalency, leading to stronger emissions at ∼900nm than at ∼1060nm. Iodide-incorporated Nd3+-doped silica fibers show prevailing ∼900nm emission rarely observed in Nd3+-doped materials. Using the created fibers, a power (113.5 W) 50 times higher than the current record is accomplished based on an all-fiber structure. Our approach holds the potential for regulating the spectroscopic properties of other rare-earth-doped laser materials.

Uncertainties about the efficacy of influenza vaccination for populations with heart failure (HF) in preventing cardiovascular outcomes, as well as lack of effective vaccination strategies, may contribute to low vaccine coverage rate (VCR) in China and globally. We assessed the feasibility of a strategy to promote influenza vaccines in patients hospitalized with acute HF in China and to inform the design of a hybrid effectiveness-implementation cluster randomized trial to evaluate this strategy on mortality and hospital re-admission. We conducted a cluster randomized pilot trial involving 11 hospitals in Henan Province in China, with mixed-methods evaluation between December 2020 and April 2021. A process evaluation involved interviews with 51 key informants (patients, health professionals, policy makers). The intervention included education about influenza vaccination and availability of free vaccines administered prior to hospital discharge for HF patients, while usual care included attending community-based points of vaccination (PoV) for screening and vaccination. Implementation outcomes focused on reach, fidelity, adoption, and acceptability. Recruitment rates were assessed for trial feasibility. Effectiveness outcomes were influenza VCR, HF-specific rehospitalizations and mortality at 90 days. A total of 518 HF patients were recruited from 7 intervention and 4 usual care hospitals (mean of 45 participants per hospital per month). VCR was 89.9% (311/346, 86.1–92.8%) in the intervention group and 0.6% (1/172, 0.0–3.7%) in the control group. The process evaluation demonstrated reach to patients with lower socioeconomic and education status. There was good fidelity of the intervention components, with education and PoV set up processes being adapted to local hospital workflow and workforce capacity. Intervention was acceptable and adopted by patients and health professionals. However, outside of a trial setting, concerns were raised around vaccination reimbursement costs, workforce accountability and capacity. The intervention strategy appears feasible and acceptable for improving VCR in HF patients at county-level hospitals in China.

Authors: Jalal Arooj , Iwamoto Kazuyo , Gedik Gulin , Ravaghi Hamid , Kodama Chiori 
Published: June 2023

Objective
The onset of COVID-19 pandemic increased the need for functioning and equipped intensive care units (ICUs) with staff trained in operating them. In the Eastern Mediterranean Region, this also triggered the need for assessing the available capacities of ICUs and health workforce so that appropriate strategies can be developed to address emerging challenges of staff shortages in the wake of COVID-19. To address this need, a scoping review on the health workforce capacity of intensive care units in the Eastern Mediterranean Region was conducted.

Methods
A scoping review methodology as outlined by Cochrane was followed. Available literature and different data sources were reviewed. Database includes Pubmed (medline,Plos included), IMEMR, Google Scholar for peer-reviewed literature, and Google for grey literature such as relevant website of ministries, national and international organization. The search was performed for publications on intensive care unit health workers for each of the EMR countries in the past 10 years (2011–2021). Data from included studies was charted, analysed and reported in a narrative format. A brief country survey was also conducted to supplement the findings of the review. It included quantitative and qualitative questions about number of ICU beds, physicians and nurses, training programs as well as challenges faced by ICU health workforce.

Results
Despite limited data availability, this scoping review was able to capture information important for the Eastern Mediterranean Region. Following major themes appeared in findings and results were synthesized for each category: facility and staffing, training and qualification, working conditions/environment and performance appraisal. Shortage of intensive care specialist physicians and nurses were in majority of countries. Some countries offer training programmes, mostly for physicians, at post-graduate level and through short courses. High level of workload, emotional and physical burnout and stress were a consistent finding across all countries. Gaps in knowledge were found regarding procedures common for managing critically ill patients as well as lack of compliance with guidelines and recommendations.

Conclusion
The literature on ICU capacities in EMR is limited, however, our study identified valuable information on health workforce capacity of ICUs in the region. While well-structured, up-to-date, comprehensive and national representative data is still lacking in literature and in countries, there is a clearly emerging need for scaling up the health workforce capacities of ICUs in EMR. Further research is necessary to understand the situation of ICU capacity in EMR. Plans and efforts should be made to build current and future health workforce.
