Impact of Diabetes Mellitus on Early Postoperative Outcomes After Hip Fracture Surgery in Geriatric Patients: A Retrospective, Propensity Score Matching Study

Background：The impact of diabetes mellitus (DM) on hip fracture (HF) is still controversial. The primary aim of this study was to examine the influence of DM on perioperative transfusion， the secondary aims were to evaluate 1-year mortality, length of stay，and total charges in individuals with hip fracture.Methods: All patients with initial HF aged 60 years or older admitted to our hospital from January 2014 to January 2018 were eligible for this study. After excluding some patients who did not meet the experimental requirements, 326 HF patients aged 60 years and above were admitted to the study institution, and were divided into DM group (n=71) and non-diabetes mellitus (non-DM) group (n=255). Sex, age, American Society of Anesthesiologists (ASA) classification, anesthesia type and surgery type were matched in the two groups (DM group vs. non-DM group) using propensity score matching (PSM) without any statistical differences. Then，perioperative transfusion，length of stay，direct total charges and 1-year mortality in individuals with HF were compared between two groups.Results: Following PSM, 62 patients in the DM group and 62 patients in the non-DM group were included in the study. Twenty-eight patients had received blood transfusion during the perioperative period, the difference in blood transfusion rate between two groups was statistically significant (p=0.032). There were no statistical differences in 1-year mortality, length of stay and direct hospital costs between two groups.Conclusions: This study showed that DM patients with hip fractures have a higher probability of receiving transfusions compared to patients without DM. Higher blood transfusion rates may be associated with lower hemoglobin and hematocrit levels at admission. However, there was no significant increase in 1-year mortality, length of hospital stay, and direct hospital costs after hip fracture surgery due to diabetes.
Atmospheric plasma: a simple way of improving the interface between natural polysaccharides and polyesters

In this study, a novel simple and fast method was developed of immobilizing a natural polysaccharide (chitosan) on a polylactide (PLA) surface. In order to overcome the lack of surface adhesion between the chitosan and the PLA due to incompatibility issues, atmospheric pressure plasma was used. The plasma activation was able to modify the PLA surface by generating surface chemistry proper for stabilizing the chitosan layer. The activation of the surface was monitored through water contact angle (WCA) measurements and X-ray photoelectron spectroscopy (XPS). Indeed, the introduction of new functionalities lowers the hydrophobicity of the PLA surface allowing an effective spreading and immobilization of the chitosan layer. The presence of chitosan on the polyester’s surface was proven by Fourier transform infrared spectroscopy (FTIR).
Geolocation of RFIs by Multiple Snapshot Difference Method for Synthetic Aperture Interferometric Radiometer

The presence of unauthorized radio frequency interference (RFI) sources seriously affects the retrieval of brightness temperature of a synthetic aperture interferometric radiometer (SAIR). Postobservation RFI geolocation is important for improving the RFI situation hereafter and mitigating the impact of the identified RFIs. Previous works have demonstrated the potential of using high-/super-resolution direction-of-arrival (DOA) estimation techniques to achieve accurate localization of RFI sources in SAIR imagery. In this article, a multiple snapshot difference method is proposed to further reduce the RFI source geolocation bias. The covariance matrices of the consecutive snapshots with power changed RFIs are picked out and subtracted to cancel out the background scene. A MUSIC-based DOA algorithm is developed. Numerical simulations validate the theoretical correctness and the practical effectiveness of the proposed method.
Boards of directors and firm performance: A study of non-financial listed firms on the Kuwait Stock Exchange

Prior to 2017, there were no corporate governance rules in Kuwait. The previous rules were silent regarding boards of directors, shareholders’ rights, disclosure, and auditing. However, at the beginning of 2017, the Kuwaiti government introduced new governance rules and required all firms listed on the Kuwait Stock Exchange (KSE) to comply with these rules. This study examined the impact of boards of directors on firm performance following the implementation of these new rules using a sample of 89 non-financial listed firms from 2017 to 2019. The study used four board variables – namely, board size, board independence, family directors, and board diversity – and found that, based on Tobin’s results, board size, board independence, and board diversity significantly impact firm performance whereas the ROA results indicate that only family directors significantly impact firm performance
Some aspects concerning the interaction of C70 fullerene with poly(L-lactic acid) (PLLA)

Abstract The equilibrium constant of the PLLA-C70 complex was determined spectrophotometrically and found at 1084 M−1, a value fully comparable with the equilibrium constant of the PLLA-C60 complex 956 M−1. In fact, both C60 and C70 share practically the same electron affinity and both are able to form charge-transfer complex with poly(L-lactic acid) (PLLA) in dichloromethane solution. The PLLA-C70 complex in CH2Cl2 solution shows also a pronounced extrinsic or induced Cotton effect when analyzed with optical rotatory dispersion (ORD) spectroscopy suggesting a kind of host-guest interaction where the helical conformation of PLLA by binding C70 internally or externally to the helical coils, is able to induce the optical activity to the achiral C70.

Knowledge Sharing in Roadmapping: Toward a Multilevel Explanation

Roadmapping is a workshop-based tool that draws on diverse sets of knowledge from individuals to create shared knowledge in the form of a roadmap for navigating a strategic landscape. Theoretical explanations of knowledge sharing in roadmapping are underdeveloped, with only limited insights into the relationship between individuals’ knowledge (at the micro level) and organizational-level outcomes. This article uses a multilevel lens to examine knowledge sharing in two roadmapping projects empirically. The analysis identifies five mechanisms that enable or constrain knowledge sharing in roadmapping: 1) a neutral space for face-to-face interactions between individuals that fosters; 2) a positive disposition of individuals to share knowledge, together with (3) imperatives to trigger knowledge contributions. Individually shared knowledge is transformed into collective outcomes via 4) shared meanings and 5) shared commitment to act. The analysis also highlights the important role of the facilitator in relation to knowledge sharing. This article extends the theoretical understanding of individuals and their behavior in the roadmapping process. In doing so, it demonstrates how microlevel actions relate to macrolevel outcomes. Practitioners, including facilitators, can use these insights as they design and deliver roadmapping interventions to improve knowledge sharing and, therefore, better strategic outcomes.
Comparison of fractal dimensions from nitrogen adsorption data in shale via different models

The roughness of pore surfaces in shale reservoirs can affect the fluid flow, which makes it necessary to be characterized. Fractal dimension, a key component in fractal geometry, can be used to describe the surface irregularities. In this paper, we evaluated and compared the fractal dimensions of several shale samples with three major fractal models based on nitrogen adsorption isotherms. The results showed that Frenkel–Halsey–Hill (FHH), Neimark, and Wang–Li models all can be applied for fractal dimension characterization of shale samples. From theoretical thermodynamics, these three models should be considered identical based on the FHH equation. However, the experimental data obtained from these samples showed that the fractal dimensions that are derived from the Neimark model and Wang–Li model are the same while a discrepancy was observed with the results from the FHH model. The difference in the fractal dimensions in the experimental data among these three models was attributed to the micropore structures. It was found that as the micropore surface area or the micropore volume increases in the samples, the difference in the fractal dimensions would increase as well. If the number of micropores present in the samples is limited, all three models can become suitable for fractal dimension calculation in shale samples, otherwise, the Neimark or Wang–Li model is preferred.
The Hearpiece database of individual transfer functions of an in-the-ear earpiece for hearing device research

We present a database of acoustic transfer functions of the Hearpiece, a commercially available multi-microphone multi-driver in-the-ear earpiece for hearing device research. The database includes HRTFs for 87 incidence directions as well as responses of the drivers, all measured at the four microphones of the Hearpiece as well as the eardrum in the occluded and open ear. The transfer functions were measured in both ears of 25 human participants and a KEMAR with anthropometric pinnae for five insertions of the device. We describe the measurements of the database and analyse derived acoustic parameters of the device. All regarded transfer functions are subject to differences between participants and insertions. Also, the KEMAR measurements are close to the median of human data in the present results for all assessed transfer functions. The database is a rich basis for development, evaluation and robustness analysis of multiple hearing device algorithms and applications. It is openly available at https://doi.org/10.5281/zenodo.3733190.

Effectiveness and Safety of Remdesivir in Patients with COVID-19: A Systematic Review and Meta-Analysis

Background: Remdesivir, a nucleoside analogue antiviral drug developed for Ebola, is approved by the US Food and Drug Administration for the treatment of COVID-19. However, the findings of randomised controlled trials (RCTs) and observational studies vary regarding the effectiveness of remdesivir. We aimed to comprehensively review the available evidence identify the effectiveness and safety of remdesivir in patients with COVID-19.Methods: Seven databases (PubMed, Web of Science, Embase, Wanfang database, SinoMed, Chinese National Knowledge Infrastructure and Chinese Science Journal Database) were searched for literatures published until November 2020.Following the PRISMA flow diagram, we included RCTs and prospective observational studies that reported the effectiveness and safety of remdesivir in patients with COVID-19. With extracting study details, as well as patient characteristics and outcomes, data were meta-analyzed by using Review Manager software version 5.4. 1. Meta-analyses were conducted with fixed-effect model or random-effect model to calculate risk ratio (RR). Results: Four studies involving 2,279 patients were included in this meta-analysis. Compared with placebo, 10-day remdesivir was associated with significant increased clinical improvement on days 14 and 28 with RR 1.19 (95%CI 1.09-1.30) and RR 1.09 (95%CI 1.03-1.16). The clinical improvement of 5-day remdesivir was better than 10-day remdesivir on days 7 with RR 1.20 (95%CI 1.02-1.41), but the efficacy advantage of 5-day remdesivir disappeared on days 14 (RR 1.08; 95%CI 0.90-1.29). Remdesivir was associated with lower serious adverse events rates and grade 3 or 4 adverse events rates as compared with placebo with RR 0.75(95%CI 0.63-0.89) and RR 0.89(95%CI 0.80-0.99). Compared with 10-day remdesivir, 5-day remdesivir for patients with COVID-19 decreased the risk of serious adverse events rates and grade 3 or 4 adverse events rates with RR 0.65(95%CI 0.47-0.88) and RR 0.74 (95%CI 0.58-0.95). Conclusions: Our meta-analysis suggested that remdesivir would increase clinical improvement conditions and decrease serious adverse events on patients with COVID-19. 5-day remdesivir had the similar clinical effectiveness and mortality with 10-day remdesivir, and had lower serious adverse events rate. Comprehensive considering the cost and benefit, 5-day remdesivir may be a better therapeutic option if available medical resources are limited.
Innovators' gains from incumbents' exit options in
 R&D
 alliances: A reconciliation of real options and transaction costs logics

Research summary The transaction costs logic suggests that innovators cannot gain value from incumbents' unconditional termination rights in their RD yet, innovators' gains from them depend on the likelihood of their opportunistic uses by incumbents at their exercises. The tests in the biopharmaceutical R&D alliances setting support our hypotheses. Managerial summary Incumbents form R&D alliances with innovators to explore new technologies and innovators join these alliances to commercialize their technologies. Yet, innovators typically possess alternative commercialization options activated once their alliances are terminated. In such R&D intensive alliances, granting unconditional termination rights to incumbents help innovators gain value from their R&D alliances. This is because incumbents' unconditional termination rights operate as their exit options and they enable easy and timely terminations of R&D alliances. This, in turn, allows innovators not to persist in troubled R&D alliances and to begin with exploring alternative commercialization options. However, the likelihood of opportunism at exit option exercises matters. The innovators' gains from exit options are likely to be higher as partner‐specific alliance experience increases because the joint history mitigates opportunism.
Identification of the functional food potency of çalkama: A traditional recipe with edible Mediterranean wild greens from Turkish cuisine

BACKGROUND: The phytochemical contents of traditional foods are necessary to further elucidate the impacts of the Mediterranean diet on health. Çalkama is traditional food prepared by using wild green plants including chard (Beta vulgaris var.cicl), wild fennel (Foeniculum vulgare spp), common mellow (Malva sylvestris L), common poppy (Papaver rhoeas L), dock (Rumex spp), common nettle (Urtica dioica L), sow-thistle (Sonchus asper (L) Hill), common stork’s bill (Erodium circutarium (L)L Hér) and wild leek (Allium ampeloprasum L). OBJECTIVE: In this research, the antioxidant activity and the flavonoid and phenolic acid composition were separately analyzed for each plant and çalkama. METHODS: Total phenolic content, total flavonoid content and total antioxidant capacity of each plant and çalkama were measured spectrophotometric assays. Ultra-fast liquid chromatography (UFLC) was performed to detect specific flavonoid groups. RESULTS: It was detected that one portion of çalkama (100 g) contained approximately 250 mg of flavonoids. Particularly, quercetin and apigenin contributed to the main flavonoid source and chlorogenic acid was the major phenolic acid in çalkama. CONCLUSIONS: According to our findings, this food can be considered as a good phenolic and flavonoid source which protects its high antioxidant capacity through preparation and cooking processes.
Mechanical and Thermo-Physical Performances of Gypsum-Based PCM Composite Materials Reinforced with Carbon Fiber

Phase change materials (PCMs) have received extensive attention due to their high latent heat storage density and isothermal behavior during heat charging and discharging processes. The application of PCMs in buildings would match energy supply and demand by using solar energy effectively, thereby reducing building energy consumption. In this study, a diatomite/paraffin (DP) composite was prepared through a vacuum-impregnated process. The thermo-physical performance, thermal stability, chemical structure and thermal reliability of the DP composite were evaluated. To develop a structural–functional integrated energy storage building material, carbon fibers (CF) were chosen as the reinforcing material. The mechanical and thermal properties of CF-reinforced DP/gypsum were examined. It is evident that the flexural strength and thermal conductivity of DP/gypsum containing 1 wt. % CF increased by 176.0% and 20.3%, respectively. In addition, the results of room model testing demonstrated that the presence of CF could enhance the overall thermal conductivity and improve the thermo-regulated performance of DP/gypsum. Moreover, the payback period of applying CF-reinforced DP/gypsum in residential buildings is approximately 23.31 years, which is much less than the average life span of buildings. Overall, the CF reinforced DP/gypsum composite is promising for thermal energy storage applications.

Job insecurity perceptions in the face of a change in labor legislation among Puerto Rican workers and its impact on productivity during an economic crisis

Article history: Received: December 12, 2020 Received in revised format: December 29 2020 Accepted: February 17, 2021 Available online: February 17, 2021 Job insecurity has evolved in a wide range of phenomena that have been little addressed in the academic literature. One of these phenomena is to observe how the implementation of labor legislation within an economic crisis affects the perception of job insecurity. Thus, this research proposes that organizational justice, organizational support, and employability become three explanatory dimensions that shape job insecurity in the face of a change in labor legislation during an economic crisis. Through a survey of 205 employees of private companies in Puerto Rico and analyzing the data through PLS-SEM, the study demonstrates and supports new literature on how each variable considered affects perceptions of job insecurity and the productivity of human capital in the face of a change in labor legislation, a topic little addressed in the academic literature. © 2021 by the authors; licensee Growing Science, Canada
