Farm to Food Bank: Exploring the Ties between Local Food Producers and Charitable Food Assistance☆
Authors: Haynes Stein Alana , Brinkley Catherine 
Published: April 2023

AbstractThis research explores the dependencies between community food security and local food movements. We use a mixed methods approach that includes: analysis of 2.97 million pounds of food bank donations from 296 organizations, network analysis of the local food system with 77 farms and 439 market connections, and 24 interviews with food bank donors and staff. We find strong ties between the food bank and local food producers, particularly producers that are organic and sell directly to the public. Nearly half the donating farms also sold to local markets; and together supplied the majority of locally produced food (296,090 pounds) distributed by the food bank. Yet, both movements operate within capitalist systems, even when the food is decommodified. Producer motivations for donating are not purely based on social responsibility to feed the hungry but also acknowledge the financial and marketing benefits of donating in terms of receiving tax credits, participating in procurement programs, and improving public relations. Our findings suggest that research and policy focused on local food systems or food security should consider such ties and their implications for growing or maintaining resulting practices.

AbstractBackgroundResearch has found that patients with suicidal ideation (SI) are at high risk for unfavorable outcomes. The present work aimed to expand the knowledge about their characteristics and treatment success.MethodsData were drawn from a routine assessment of N = 460 inpatients. We used patients' self‐report data as well as therapists' reports covering baseline characteristics, depression and anxiety symptoms (at the start and end of therapy), psychosocial stress factors, helping alliance, treatment motivation, and treatment‐related control expectancies. In addition to group comparisons, we conducted tests of associations with treatment outcome.ResultsSI was reported by 232 patients (50.4% of the sample). It co‐occurred with higher symptom burden, more psychosocial stress factors, and negation of help. Patients reporting SI were more likely to be dissatisfied with the treatment outcome (although their therapists were not). SI was related to higher levels of anxiety symptoms after treatment. In regression models of depression and anxiety symptoms, interactions of SI with the external control expectancy powerful others were observed, suggesting that in patients with frequent SI, this control expectancy hindered recovery.Discussion/ConclusionPatients reporting SI are a vulnerable group. Therapists could support them by addressing (potentially conflicting) motivations and control expectancies.

AbstractObjectiveTo evaluate the capacity of the automatic detection system to accurately grade, from selfie pictures, the severity of eight facial signs in South African men.MethodsSelfie pictures (obtained from frontal and back cameras) of 281 South African men differently aged (20–70 years) were obtained and analyzed by an automatic artificial intelligence (AI)‐based automatic grading system. Data were compared with the clinical gradings made by experts and dermatologists.ResultsIn all facial signs, both series of gradings were found highly correlated with, however, different coefficients (0.59–0.95), those of marionette lines and cheek pores being of lower values. No differences were observed between data obtained by frontal and back cameras. With age, in most cases, gradings show up to the 50–59 year age‐class, linear‐like changes. When compared to men of other ancestries, South African men present lower wrinkles/texture, pigmentation, and ptosis/sagging scores till 50–59 years, albeit not much different in the cheek pores sign. The early onset (mean age) of visibility of wrinkles/texture for South African men were (i.e., reaching grade >1) 39 and 45 years for ptosis/sagging.ConclusionThis study completes and enlarges the previous works conducted on men of other ancestries by showing some South African specificities and slight differences with men of comparable phototypes (Afro American).

AbstractBackgroundRobust evidence to inform best transfusion management after major oncologic surgery, where postoperative recovery might impact treatment regimens for cancer, is lacking. We conducted a study to validate the feasibility of a larger trial comparing liberal versus restrictive red blood cells (RBC) transfusion strategies after major oncologic surgery.Study Design and MethodsThis was a two‐center, randomized, controlled, study of patients admitted to the intensive care unit after major oncologic surgery. Patients whose hemoglobin level dropped below 9.5 g/dL, were randomly assigned to immediately receive a 1‐unit RBC transfusion (liberal) or delayed until the hemoglobin level dropped below 7.5 g/dL (restrictive). The primary outcome was the median hemoglobin level between randomization to day 30 post‐surgery. Disability‐free survival was evaluated by the WHODAS 2.0 questionnaire.Results30 patients were randomized (15 patients/group) in 15 months with a mean recruitment rate of 1.8 patients per month. The median hemoglobin level was significantly higher in the liberal group than in the restrictive group: 10.1 g/dL (IQR 9.6–10.5) versus 8.8 g/dL (IQR 8.3–9.4), p < .001, and RBC transfusion rates were 100% versus 66.7%, p = .04. The disability‐free survival was similar between groups: 26.7% versus 20%, p = 1.DiscussionOur results support the feasibility of a phase 3 randomized controlled trial comparing the impact of liberal versus restrictive transfusion strategies on the functional recovery of critically ill patients following major oncologic surgery.

AbstractObjectiveTo describe a craniectomy using a lateral, transzygomatic approach to the middle fossa and rostral brainstem, and to report clinical outcomes and complications in three dogs.AnimalsTwo cadaver dogs and three client‐owned dogs. Two of the client‐owned dogs with middle fossa lesions, and one with a rostral brainstem lesion.MethodsTwo cadavers were used to describe the lateral, transzygomatic surgical approach to the middle fossa and rostral brainstem. The medical records of three dogs undergoing this surgical approach were reviewed for data on signalment, preoperative and postoperative neurological status, diagnostic imaging, surgical technique, complications, and outcome.ResultsIndications for this surgical approach included incisional biopsy (n = 1) and debulking surgery for brain lesions (n = 2). Definitive diagnoses were achieved in two cases, and tumor volume reduction in all cases. Two of the three dogs developed postoperative facial nerve paralysis ipsilateral to the surgical site, which resolved within 2 and 12 weeks after surgery.ConclusionThe lateral, transzygomatic approach provided useful access to ventrally located cerebral/skull base lesions in dogs without major complications.

Abstract
We present an experimental investigation of spatial audio feedback using smartphones to support direction localization in pointing tasks for people with visual impairments (PVIs). We do this using a mobile game based on a bow-and-arrow metaphor. Our game provides a combination of spatial and non-spatial (sound beacon) audio to help the user locate the direction of the target. Our experiments with sighted, sighted-blindfolded, and visually impaired users show that (a) the efficacy of spatial audio is relatively higher for PVIs than for blindfolded sighted users during the initial reaction time for direction localization, (b) the general behavior between PVIs and blindfolded individuals is statistically similar, and (c) the lack of spatial audio significantly reduces the localization performance even in sighted-blindfolded users. Based on our findings, we discuss the system and interaction design implications for making future mobile-based spatial interactions accessible to PVIs.
A Vision-Based Human Digital Twin Modeling Approach for Adaptive Human–Robot Collaboration

Published: April 2023

Abstract
Human–robot collaboration (HRC) has been identified as a highly promising paradigm for human-centric smart manufacturing in the context of Industry 5.0. In order to enhance both human well-being and robotic flexibility within HRC, numerous research efforts have been dedicated to the exploration of human body perception, but many of these studies have focused only on specific facets of human recognition, lacking a holistic perspective of the human operator. A novel approach to addressing this challenge is the construction of a human digital twin (HDT), which serves as a centralized digital representation of various human data for seamless integration into the cyber-physical production system. By leveraging HDT, performance and efficiency optimization can be further achieved in an HRC system. However, the implementation of visual perception-based HDT remains underreported, particularly within the HRC realm. To this end, this study proposes an exemplary vision-based HDT model for highly dynamic HRC applications. The model mainly consists of a convolutional neural network that can simultaneously model the hierarchical human status including 3D human posture, action intention, and ergonomic risk. Then, on the basis of the constructed HDT, a robotic motion planning strategy is further introduced with the aim of adaptively optimizing the robotic motion trajectory. Further experiments and case studies are conducted in an HRC scenario to demonstrate the effectiveness of our approach.
Burst of Internally Pressurized Steel Torispheres
Authors: Błachut J. 
Published: April 2023

Abstract
The paper begins with derivation of true stress–true strain data, including postnecking section. Available results of past uni-axial tests on round 10 mm diameter and 200 mm long mild steel samples are the basis of the conversion. The steel in question was used to manufacture ten torispherical domes that were in the past tested for burst. Hence, the relevance of matching material model is necessary for the finite elements (FE), analyses. In the past, plastic instability and constraints on the magnitude of plastic strains were postulated as criteria for the burst of internally pressurized torispheres. These criteria for burst pressure are being examined and benchmarked against the tests. The current paper, using the FE analyses, shows that modification of constraints on plastic strains has only marginal effect on the burst which still remains on the unsafe side of test data by a sizeable margin. The same is found to be true for plastic instability criterion. Subsequent computations moved back to the use of engineering stress–strain. Then, two types of computing are carried out here, based on multisegment and bilinear modeling of material. Computed results of burst pressure follow the test data to within (−6%, +10%). These results are far better than all the previous.

Abstract
Swirl cooling can provide effective protection for the turbine vane leading edge (LE). In this paper, a swirl cooling model for improving the turbine vane heat transfer is established. The model includes the high-temperature mainstream region, LE region, and swirl cooling region. The conjugate heat transfer (CHT) method is used to examine the influence of wall structures on swirl cooling. Then, the best surface structure in the studied range is selected to further analyze the impact of the coolant inlet mass flow. The results show that the circumferential micro-rib structure has a more excellent performance in both fluid flow and cooling performance. The hindering effect of the micro-ribs can effectively avoid the development of axial cross-flow, thus enhancing the heat transfer with a small friction loss increment and providing a lower surface temperature and more uniform temperature distribution. When the inlet mass flowrate improves, the thermal performance factor increases and the LE temperature decreases gradually. Under the same pumping power condition, the circumferential micro-ribs structure has higher heat transfer efficiency. This investigation can provide a new design for further improving the thermal performance of swirl cooling for turbine vanes.

Published: April 2023

Abstract
This work is an experimental study of film cooling effectiveness on two real-scale turbine vanes in a three-vane annular cascade. The cascade is connected to a high-flow steady compressor to provide the mainstream flow. The inlet velocity is maintained at 35 m/s at the centerline of the annular cascade. Two heavily cooled, real-scale turbine vanes are tested with cooling holes on the pressure (PS) and suction (SS) surfaces. Vane 1 has 645 cooling holes distributed around the vane. Vane 2 has an additional two rows of holes at the near leading edge SS of the vane. The mass flow ratio (MFR) is varied from 3.12% to 4.82%. Increasing the MFR increases film effectiveness. The introduction of additional rows of cooling holes resulted in the re-distribution of coolant from the pressure surface to the suction surface. The re-distribution of coolant is primarily due to the additional coolant supplied to the suction surface for vane 2. This study provides designers with more insight into how to place rows of cooling holes to have improved effectiveness.

Purpose: To compare the load and wellness of second-team academy football players during a first-team preseason with those of first-team players and those of their previous second-team preseason. Methods: Athletic Club’s first- (n = 10) and second-team (n = 9) players were prospectively followed during the 2019–20 first- and second-team and 2020–21 first-team preseasons. Weekly external and internal loads and average wellness z-scores (fatigue, sleep quality, muscle soreness, stress, and mood) were compared between preseasons and teams. Results: While training together during the 2020–21 preseason, second-team players performed more decelerations <−3 m/s2 per week than first-team players (moderate effect size). For first-team players, there were only small differences between preseasons in external load, but session rating of perceived exertion was higher (moderate) and stress (moderate) and mood (large) z-scores were worse in 2020–21. For second-team players, more total distance (large), accelerations >3 m/s2 (large), and decelerations <−3 m/s2 (very large) were performed; total loading (moderate) and session rating of perceived exertion (moderate) were higher; and fatigue (very large) and stress (moderate) z-scores were worse during the 2020–21 first-team preseason compared to their previous second-team preseason. Conclusions: Players transitioning from the second team faced higher external and internal loads, fatigue, and stress during the first-team preseason compared to the previous second-team preseason. Player development and monitoring plans appear necessary to manage the transition from the academy to the first team.
Exercise and Protein Supplementation Recommendations for Older Adults With Sarcopenic Obesity: A Meta-Review
Authors: Contillo Allison T. , Rodriguez Nancy R. , Pescatello Linda S. 
Published: April 2023

This systematic meta-review evaluated the effects of exercise with and without protein interventions on muscle strength and function in older adults with sarcopenic obesity. PubMed, Cochrane Database of Systematic Reviews, Cumulative Index to Nursing and Allied Health Literature, Scopus, and SPORTDiscus databases were searched through February 2021 for relevant systematic reviews and meta-analyses with aerobic, resistance, and/or combined training interventions with and without protein supplementation in older adults ≥ 65 years with sarcopenic obesity. This meta-review showed that exercise with and without protein supplementation improved body composition (i.e., decreased percentage body fat) and functional outcomes (i.e., gait speed and grip strength). Because the current literature is limited, determining the effects of exercise and combined protein supplementation in this population requires further investigation. In the meantime, protein recommendations should align with general sarcopenia recommendations. Based upon available findings, tentative exercise recommendations to optimize health outcomes in this population are proposed.
Overcoming the “Ostrich Effect”: A Narrative Review on the Incentives and Consequences of Questionable Research Practices in Kinesiology
Authors: Tiller Nicholas B. , Ekkekakis Panteleimon 
Published: April 2023

Increasing transparency and openness in science is an ongoing endeavor, one that has stimulated self-reflection and reform in many fields. However, kinesiology and its related disciplines are among those exhibiting an “ostrich effect” and a reluctance to acknowledge their methodological shortcomings. Notwithstanding several high-profile cases of scientific misconduct, scholars in the field are frequently engaged in questionable research practices (QRPs) such as biased experimental designs, inappropriate statistics, and dishonest/inexplicit reporting. To advance their careers, researchers are also “gaming the system” by manipulating citation metrics and publishing in predatory and/or pay-to-publish journals that lack robust peer review. The consequences of QRPs in the discipline may be profound: from increasing the false positivity rate to eroding public trust in the very institutions tasked with informing public health policy. But what are the incentives underpinning misconduct and QRPs? And what are the solutions? This narrative review is a consciousness raiser that explores (a) the manifestations of QRPs in kinesiology; (b) the excessive publication pressures, funding pressures, and performance incentives that are likely responsible; and (c) possible solutions for reform.
Calculating Vertical Ionization Energies of Hydrated Biological Chromophores Based on Multiconfigurational Perturbation Theory
Authors: Boichenko A. N. , Bochenkova A. V. 
Published: April 2023

Abstract
Here we introduce a methodology for calculating vertical detachment energies (VDE) and vertical ionization energies (VIE) of anionic and neutral chromophores in aqueous environment. The proposed method is based on the extended multiconfigurational quasidegenerate perturbation theory coupled to the explicit treatment of solvent effects in the frame of the effective fragment potential method. We show that the solvent polarization contribution must be considered for getting accurate quantitative estimations of VDEs and VIEs. The calculated values of VDE for phenolate (7.3 eV) and VIE for phenol (7.9 eV) in aqueous environment are in good agreement with the experimental results obtained using X-ray and multiphoton UV photoelectron spectroscopy. Our approach will be useful for studying processes of photoinduced electron transfer from anionic as well as neutral biological chromophores in aqueous solution.

IntroductionIn 2015/2016, annual national expenditure on neurological conditions exceeded $A3 billion. However, a comprehensive study of the Australian neurological workforce and supply/demand dynamics has not previously been undertaken.MethodsCurrent neurological workforce was defined using neurologist survey and other sources. Workforce supply modelling used ordinary differential equations to simulate neurologist influx and attrition. Demand for neurology care was estimated by reference to literature regarding incidence and prevalence of selected conditions. Differences in supply versus demand for neurological workforce were calculated. Potential interventions to increase workforce were simulated and effects on supply versus demand estimated.ResultsModelling of the workforce from 2020 to 2034 predicted an increase in neurologist number from 620 to 896. We estimated a 2034 capacity of 638 024 Initial and 1 269 112 Review encounters annually, and deficits against demand estimated as 197 137 and 881 755, respectively. These deficits were proportionately greater in regional Australia, which has 31% of Australia’s population (Australian Bureau of Statistics) but is served by only 4.1% of its neurologists as determined by our 2020 survey of Australia and New Zealand Association of Neurologists members. Nationally, simulated additions to the neurology workforce had some effect on the review encounter supply deficit (37.4%), but in Regional Australia, this impact was only 17.2%.InterpretationModelling of the neurologist workforce in Australia for 2020–2034 demonstrates a significant shortfall of supply relative to current and projected demand. Interventions to increase neurologist workforce may attenuate this shortfall but will not eliminate it. Thus, additional interventions are needed, including improved efficiency and additional use of support staff.
