Authors: Sheng Shaojun
Published: December 2023

One of the challenges that businesses have always paid more attention to is supply chain logistics competence. The conditions of supply chain logistics capabilities management have also altered in light of the quick development of multimedia, and there will undoubtedly be certain management issues. Logistics competence is expressed in both real and intangible capabilities in the context of the supply chain. As a result, this paper presents research on supply chain logistics capability management strategy based on the distributed platform under the multimedia background, elaborates on the supply chain logistics capability optimization standard under the multimedia background, analyzes the impact of multimedia background on supply chain logistics capability management, establishes a new type of supply chain relationship and strengthens the judgment of enterprise market information. This study concludes by proposing measures for supply chain logistics capability management, such as enhancing the infrastructure for supply chain logistics capability management and strengthening supplier management. The experimental findings demonstrate that we can effectively increase the supply chain’s supply efficiency, achieve a 13% performance improvement and reduce the cost of the supply chain by using the logistics framework in a distributed environment.

In this study, the photocatalytic degradation of RhB dye in an aqueous solution using ZnO nanoparticles (NPs), [Formula: see text]-Fe2O3, [Formula: see text]-Fe2O3–ZnO, Ag–ZnO, and [Formula: see text]-Fe2O3–Ag–ZnO nanomaterials generated using poinciana leaf extract is presented. The nanomaterials were prepared utilizing environmentally friendly methods and poinciana leaf extract. The properties of the originally generated nanomaterials, analyzed through techniques such as atomic force microscopy (AFM), UV–visible spectroscopy, X-ray, electron microscopy, and FE-SEM, have been described. The hexagonal structure of ZnO wurtzite was also discovered to align with the XRD findings. Additionally, EDX mapping was employed to analyze the composition of the [Formula: see text]-Fe2O3–Ag–ZnO nanocomposite. A topological investigation confirmed the roughness of the created nanostructures. Regarding the photocatalytic Rhodamine B (RhB) dye degradation studies, the [Formula: see text]-Fe2O3–Ag–ZnO nanocomposite demonstrated superior performance compared to pure ZnO in breaking down dye molecules under visible light exposure. Employing an ideal configuration of 1.0 g/L of photocatalyst, pH 10, and 10 ppm of RhB, an impressive photodegradation effectiveness of nearly 99% was achieved in just 45 min of light exposure. An analysis of reactive species was conducted to determine the photodegradation efficiency of [Formula: see text]-Fe2O3–Ag–ZnO. To investigate the impact of the microorganisms Escherichia coli and Staphylococcus aureus on the [Formula: see text]-Fe2O3–Ag–ZnO nanocomposite, the results indicated that the [Formula: see text]-Fe2O3–Ag–ZnO nanocomposite achieved a high rate of success in neutralizing and eradicating these bacteria.
Theoretically Derived Transfer Functions and Specific Framework for Simulating Spatially Varying Seismic Underground Motions of Media-Transition Site
Authors: Liu Guohuan , Li Xinyang
Published: December 2023

Extended projects usually undergo different motions at their supports located at varying soil property conditions when an earthquake occurs. A theoretical framework including the key transfer function is proposed for simulating multi-support seismic underground motions in media-transition sites. First, a multi-layer media-transition site is illustrated. Then, the transfer function is theoretically derived and given explicitly using seismic wave propagation theory and fulfilling rigorously continuous boundary conditions. The obtained transfer function is the critical factor to calculate the underground Auto-Power Spectral Density (A-PSD). Meanwhile, the derivation and illustration of the other key factor (i.e. underground coherency function) is also given and the essential effect caused by media transition is further disclosed. The underground Cross-Power Spectral Density (C-PSD) is obtained by combining the underground coherency function with the transfer function. The underground Power Spectral Density Matrix (PSDM) is finally assembled by combining the A-PSD with C-PSD. Subsequently, multi-support seismic motions at varying depths of the media-transition site are generated, and its accuracy is further validated. Additionally, a numerical study is conducted to demonstrate the effect of water and soil phase on transfer functions and the underground seismic motions among dual-phase and media-transition sites. Results show the difference of seismic underground motions in two sites is obvious. This paper can provide a specific and feasible methodology for generating the multi-support seismic underground motions.

Published: December 2023

Objective. To analyze and evaluate the clinical value of hetrombopag in cancer therapy-induced thrombocytopenia (CTIT) caused by antitumor therapy for malignant tumors and to provide scientific evidence support for clinical application in the real-world setting. Methods. The clinical data of CTIT patients with advanced solid tumors who received hetrombopag were analyzed retrospectively. The proportion of patients with different characteristics who recovered platelet count to ≥75 × 109/L at day 14 and the effective rate of platelet elevation was compared by the χ2 test or Fisher exact probability method. P<0.05 was considered statistically significant. Results. A total of 60 CTIT patients who received hetrombopag at our site from July 2021 to October 2022 were finally included in this study. The proportion of patients who achieved therapeutic effect within (7 ± 2) days after treatment was 26.7% (16/60), among which 20.0% (12/60) patients had platelet count recovered to ≥100 × 109/L, and 25.0% (15/60) patients had platelet count increase from baseline ≥50 × 109/L. Within (14 ± 2) days of treatment with hetrombopag, 66.7% (40/60) of patients achieved treatment response, of whom 56.7% (34/60) had platelet counts ≥100 × 109/L and 53.3% (32/60) had platelet counts ≥50 × 109/L increase from baseline. In addition, no treatment-related adverse events occurred during the treatment period. Conclusion. This retrospective study provides preliminary evidence that hetrombopag increases platelets in CTIT patients receiving antitumor therapy for advanced solid tumors.

Authors: Ma Yan , Han Yingkun , Zeng Haonan , Ma Lei
Published: December 2023

Sci-Tech journals have long served as platforms for academic communication and the collision of ideas, facilitating advanced inventions and major discoveries in science. The speed of development and future prospects of a field in the current era can often be reflected by the quality and quantity of cutting-edge papers published in Sci-Tech journals within that field. Currently, the impact factor of Sci-Tech journals is a widely recognized journal evaluation index that comprehensively reflects the quality and influence of the journals under evaluation. However, traditional journal evaluation methods based on statistical formulas, while relatively simple and fast, have certain limitations. They are not comprehensive enough and do not support the comparison between journals from different disciplines. In recent times, researchers have delved into using multiple suitable indicators for comprehensive journal evaluation, attempting to understand the role each indicator plays in the evaluation process, such as the rank sum ratio. Our paper presents a new dataset constructed from data from journals across various fields obtained from the China Wanfang Literature Platform. We endeavor to explore a series of novel journal evaluation methods based on machine learning, including deep learning models. With these 9 methods, we aim to determine the contribution of 17 journal evaluation indicators to the impact factor and identify important factors that can further enhance the quality and influence of Sci-Tech journals, which has great guiding significance for the future development of journals.
The Impact of Raising Children with Barth Syndrome on Parental Health-Related Quality of Life and Family Functioning: Preliminary Reliability and Validity of the PedsQL™ Family Impact Module
Authors: Lim Yoonjeong , Hong Ickpyo , Han Areum
Published: December 2023

Objective. This study examined the preliminary reliability and validity of the PedsQL™ Family Impact Module (PedsQL FIM) in families of children with Barth syndrome (BTHS). Method. A total of 72 parents with children or youth between the ages of 5 and 19 participated in this study. Thirty-three parents of children with BTHS and 39 parents of unaffected children completed the PedsQL FIM and a demographic information form. Internal consistency reliability and item-total correlations were calculated to test the reliability of the PedsQL FIM. Construct validity was examined using the known-groups method. We estimated the mean score differences of the PedsQL FIM between the two groups using three different models, including unadjusted, multivariate regression, and propensity score matching with inverse probability of treatment weighting (PS-IPTW) models. Results. The Cronbach’s alpha coefficients were greater than 0.70 for all scales of the PedsQL FIM, except for the communication scale. The item-total correlations were significant for all scales with moderate to high correlations (p<.05). In construct validity, the mean scores of the PedsQL FIM between the two groups were significantly different (p<.05) for all scales and total score in the unadjusted and PS-IPTW models. However, in the multivariate regression model, the family relationships scale was not significant between the two groups. Conclusion. The PedsQL FIM demonstrated adequate measurement properties of preliminary reliability and validity in assessing the impact of children with BTHS on parental health-related quality of life (HRQoL) and family functioning. Further research needs to be conducted to examine the psychometric properties of the PedsQL FIM with a large sample of BTHS and with other pediatric rare diseases.

Published: December 2023

Background. The morphology of the papillary muscles of the left ventricle is highly variable. Few studies have investigated papillary muscle morphology using imaging. Objective. This study aimed to assess papillary muscle morphology with primary mitral regurgitation (MR) using cardiac computed tomography (CT). Methods. We examined 116 patients who underwent robotic mitral valve repair for primary MR using preoperative cardiac CT. Papillary muscle morphology was assessed using CT images and compared with operative findings. Results. CT images of papillary muscles were consistent with the operative findings during robotic mitral valve repair in all cases. Both the anterolateral papillary muscle (APM) and posteromedial papillary muscle (PPM) groups were identified in all cases, and the middle papillary muscle (MPM) group was identified in 24.1% of cases. The PPM group had a higher proportion of complex morphologies with more heads and bases than the APM group (head: p<0.001 and base: p<0.001). The PPM group had smaller papillary muscle sizes than the APM group. The MPM group in most patients had one base and one head (78.6%). Papillary muscle sizes were significantly smaller in the order of the APM, PPM, and MPM groups (p<0.001). Conclusions. Cardiac CT allowed clear visualization and accurate assessment of papillary muscle morphology in the left ventricle. It may be useful to obtain the papillary muscle variations preoperatively using CT imaging in procedures involving the papillary muscles such as mitral valve repair.

Published: December 2023

Objectives. We aimed to establish an effective machine learning (ML) model for predicting the risk of distant metastasis (DM) in medullary thyroid carcinoma (MTC). Methods. Demographic data of MTC patients were extracted from the Surveillance, Epidemiology, and End Results (SEER) database of the National Institutes of Health between 2004 and 2015 to develop six ML algorithm models. Models were evaluated based on accuracy, precision, recall rate, F1-score, and area under the receiver operating characteristic curve (AUC). The association between clinicopathological characteristics and target variables was interpreted. Analyses were performed using traditional logistic regression (LR). Results. In total, 2049 patients were included and 138 developed DM. Multivariable LR showed that age, sex, tumor size, extrathyroidal extension, and lymph node metastasis were predictive features for DM in MTC. Among the six ML models, the random forest (RF) had the best predictability in assessing the risk of DM in MTC, with an accuracy, precision, recall rate, F1-score, and AUC higher than those of the traditional binary LR model. Conclusion. RF was superior to traditional LR in predicting the risk of DM in MTC and can provide a valuable reference for clinicians in decision-making.

Growth and yield of maize applicated by Rizhobium spp. from legume and non-legume rhizosphere
Authors: Widodo Tirto Wahyu , Muhklisin Ilham , Nugroho Setyo Andi , Wardana Rudi , Ummah Umi Safitri Alifia
Published: December 2023

Rhizobium spp can affect plant growth in non-legume crops directly by synthesis of phytostimulator and solubilization of inorganic phosphate. However, the ability of Rhizobium spp from legume and non-legume rhizosphere to trigger the growth of non-legume crops is different. This research aims to analyze the ability of Rhizobium spp isolates to produce IAA hormones and phosphate solvent and determine the response of maize with the application of Rhizobum spp from the legume and non-legume rhizosphere. This study was carried out in two stages, where the first stage at Bioscience Laboratory Politeknik Negeri Jember, while the second stage at Kaliurang field, Jember, Indonesia (altitude 146 m asl, temperature 21°C - 34°C, and soil type was incepstisol) from September 2022 to January 2023. The field experiment was arranged in a complete randomized design (crd) with the application of Rhizobium spp isolates from various rhizosphere as a treatment consisting of without Rhizobium spp (control), maize-rhizosphere isolate, rice-rhizosphere isolate, soybean-rhizosphere isolate, edamame-rhizosphere isolate, and peanut-rhizosphere isolate. Every treatment was replicated four times. The results showed that Rhizobium spp isolates from legume and non-legume rhizospheres can synthesize indole acetic acid and solubilize phosphate. This condition was indicated by the solubilized phosphate content in the planting medium, which was higher in the application of Rhizobium spp compared to the control. Inoculation of Rhizobium spp from several rhizospheres showed a significant effect on plant height, stem diameter, ear weight without husks, and ear dry weight compared to control. These bacteria are able to trigger the growth of maize through direct and indirect mechanisms. In addition, the plant height that was treated with maize-rhizosphere Rhizobium spp was better than rice. It is suspected that Rhizobium spp from the maize rhizosphere is more adaptable when applied to growing media for maize crops, so that it can increase plant height.
The Slavonic Solunskaja Legenda (“The Legend of Thessalonica”) and Its Syriac Original
Authors: Lourié Basil
Published: December 2023

The Slavonic eschatological apocryphon Solunskaja Legenda (“The Legend of Thessalonica”) is a direct translation from Syriac. The archetype of the extant recensions is datable to 893–972. It was created, in the First Bulgarian Empire, on the base of an earlier Slavonic text that did not mention the Bulgarians. The Sitz im Leben of the original Syriac recension and its Slavonic translation is a Syrian monothelete colony in North Macedonia (then, a part of Byzantium) between 752/754 and 839/842. The legend echoed events related to a successful Syriac monothelete mission to a slavinia (Slavic enclave headed by an autonomous prince) in the region of Thessalonica in the 670s or 680s. The legend describes the creation of the first Slavonic alphabet, and it uses specific terminology for writing tools. In its Slavonic translation, this terminology was transliterated instead of being translated. It can be assumed that the translator wanted to introduce new terms into the Slavonic language in this way.
Grotius’s Contribution to the Law of Secured Credit
Authors: van Hoof Vincent J. M.
Published: December 2023

Over the centuries, Grotius’s writings on onderzetting (rights of hypothec) have been widely cited, particularly in the Netherlands and South Africa. This article investigates the originality and lasting impact of Grotius’s contributions to this field. The article follows the layout of the chapter on hypothecs of Grotius’s Inleiding tot de Hollandsche Rechts-geleertheyd. It examines Grotius’s translation of hypotheca as onderzetting, the structure of his Inleiding, the distinctions between various kinds of hypothec, and contemporary requirements for the creation of hypothecs. It then explores the right to follow encumbered assets into the hands of third parties and analyses the enforcement of hypothecs, priority issues in cases of competing hypothecs, and reflects on Grotius’s influence on Dutch security rights. In summary, although Grotius’s insights were largely derivative, often echoing interpretations of earlier scholars, they illustrate Grotius’s deep understanding of the influence of Germanic and Roman law on Roman-Dutch security rights. Grotius had a lasting impact on legal scholarship and practice because he was the first to provide a scholarly systematization of Roman-Dutch law within the framework of Justinian’s Institutes and firmly placed the rights of hypothec in the book on property rights of his Inleiding.
Grotius and Insolvency
Authors: den Hollander Maurits
Published: December 2023

This article considers Hugo Grotius’s ideas on a specific topic of commercial law, analysing his position and potential contributions to early modern Dutch insolvency legislation. It might be questioned how ‘Hollandic’ Grotius’s interpretations of legal solutions for insolvency as presented in the Inleidinge tot de Hollandsche Rechts-Geleerdheid actually were. Grotius’s treatment of cessie van goede is relatively strict, whereas compositions are hardly mentioned. A rather different image rises from his later work. Here, Grotius displays a more radical view, in specific cases allowing the sovereign to interfere in private property rights and to restructure debts for the common good. It is an intriguing question if and to what extent these ideas can be related to contemporary Dutch insolvency practices.
Islamic Radical Political Thought and the Struggle for a Righteous Society: Sayyid Quṭb’s Al-ʿadāla al-iǧtimāʿiyya fīʾl-Islām (Social Justice in Islam)
Authors: Manduchi Patrizia
Published: December 2023

This article aims to investigate if and how Sayyid Quṭb’s social insights can be considered an example of radical political thought – not in an Islamic sense, but as one of the “counter-hegemonic articulations” within the Egyptian political debate in the 1940s and 1950s. The essay also wants to re-discuss the widespread belief that Qutb’s intellectual production underwent a clear transition in two distinct periods of his life. In fact, Quṭb’s political thought is generally described (especially by those who only consider him as the mentor of international jihadism) as initially characterized by a phase of nationalistic commitment and later by his “changeover” to extremist, fanatical and violent Islamism. To underline how this transition was in fact far more nuanced and gradual, I will focus on Quṭb’s essay Al-ʿadāla al-iǧtimāʿiyya fīʾl-Islām (1949), its particular editorial history and its enormous resonance among Egyptian intellectuals.
The Social Foundations of Academic Freedom: Heterogeneous Institutions in World Society, 1960 to 2022
Authors: Lerch Julia C. , Frank David John , Schofer Evan
Published: December 2023

This article analyzes academic freedom worldwide with newly available cross-national data. The literature principally addresses impingements on academic freedom arising from religion or repressive states. Academic freedom has broadly increased since 1945, but we see episodic reversals, including in recent years. Conventional work emphasizes the uniformity of international institutional structures and their influence on countries. We attend to the heterogeneity of international structures in world society and theorize how they contribute to ebbs and flows of academic freedom. Post-1945 liberal international institutions enshrined key rights and norms that bolstered academic freedom worldwide. Alongside them, however, illiberal alternatives coexisted. Cold War communism, for instance, anchored cultural frames that justified greater constraints on academia. We evaluate domestic and global arguments using regression models with country fixed effects for 155 countries from 1960 to 2022. Findings support conventional views: academic freedom is associated positively with democracy and negatively with state religiosity and militarism. We also find support for our argument regarding heterogeneous institutional structures in world society. Country linkages to liberal international institutions are positively associated with academic freedom. Illiberal international structures and organizations have the opposite effect. Heterogeneous institutions in world society, we contend, shape large-scale trajectories of academic freedom.
The Power of Diversity: Class, Networks and Attitudes Towards Inequality
Authors: Otero Gabriel , Mendoza Manuela
Published: December 2023

We examine how inter-class relationships shape attitudes towards inequality. Our theoretical frame defines attitudes towards inequality as ethical dispositions and hypothesises that class-based network diversity may favour the development of what has been termed a ‘reflexive habitus’ that likely pushes for more egalitarian dispositions. The focus of our enquiry is on Chile – one of the most unequal countries in the world. We use large-scale representative survey data collected in 2016 (N = 2927). Results of our regression analyses indicate that class diversity in social networks strongly increases awareness of inequality and more egalitarian preferences while reducing belief in meritocracy and the perception that the current distribution is fair. Additional analyses suggest that network diversity influences views on inequality to a similar degree among individuals from different social classes, except for meritocratic beliefs, where network diversity especially affects the upper class. We conclude by discussing the importance of reducing socio-economic segregation.
Rebirth from the ashes: Failure events and new venture creation in Norway
Authors: Wang Pengfei
Published: December 2023

How do failure events affect subsequent new venture creation? The existing literature seems to point in two opposing directions. While the information perspective suggests that failure events undermine collective beliefs about market viability, the competition view implies that failures may foster entrepreneurship via easing competition in both factor and product markets. To address this question, we adopt an inductive approach and analyse registry data in Norway. Based on the firm-level microdata, we construct an industry-region-level marketspace to analyse the number of firm failures and new ventures in different markets. Results show that failures of existing firms generally lead to more venture creation in the same market, albeit being contingent on industry features. And such effect is mainly ‘pulled’ by product market vacuum, rather than ‘pushed’ by factor abundance. However, we also observe that ventures that are created following failure events are less likely to survive.
Social exchange or reinforcement of women’s educational advantage? The influence of educational assortative mating on occupational assortative mating for couples in Spain
Authors: López-Rodríguez Fermín , Gutiérrez Rodolfo
Published: December 2023

The reversal of the gender gap in education has transformed traditional patterns of assortative mating, increasing the number of hypogamous couples. This change has been particularly intense in the case of Spain, a country of great interest due to the ambivalence of strong support for egalitarian attitudes and high proportion of traditional couples. Using quarterly microdata from the Spanish Labour Force Survey, applying generalised ordered-logit models, this research reveals that educational hypogamy increases the probability of occupational hypogamy. This association is consistent with the use of different occupational classifications and levels of disaggregation. But there are some factors that limit the transmission of women’s educational advantages to their occupational levels, mainly gender differences in access to the labour market and an uneven distribution of professional achievements by sex. The findings obtained underline the relevance of using different measures as well as different theoretical approaches to explain seemingly contradictory couple equilibria.

Published: December 2023

In this study, the melt polycondensation reaction of 9,9’- bis(4-hydroxyphenyl)fluoride (BHPF) and diphenyl carbonate (DPC) was catalyzed using three ionic liquids (ILs) and a conventional alkali metal as catalysts. The optimal IL catalysts were determined to be [BMmim][BF4] ionic liquid catalysts, and the catalytic mechanism was investigated. Furthermore, the optimum process conditions were identified: the optimal amount of [BMmim][BF4] was 0.05 mol% based on DPC, the polycondensation temperature was set at 200°C for a duration of 3 h, followed by polymerization at 280°C for another 3 h. As a result, the Mn value of poly(9,9-bis(4-hydroxyphenyl) carbonate) (PFC) reached up to 41387 g/mol with a glass transition temperature band of approximately 254°C and Td-5% value of around 436°C.
A multimodal fusion positioning method with adaptive driving behavior for intelligent vehicles
Authors: Zhang Ziyu , Wang Chunyan , Zhao Wanzhong , Cao Mingchun , Liu Jinqiang
Published: December 2023

Due to the difficulty of Global Navigation Satellite System (GNSS) in urban canyon environments, GNSS and inertial navigation system (INS) fusion positioning is widely used in the field of intelligent driving. In actual positioning, INS usually uses the vehicle physical model as a constraint to calculate inertial measurement unit (IMU) data to supplement the vehicle position and attitude as GNSS positioning information. However, the existing algorithms usually use a fixed physical model. When the vehicle’s driving behavior changes, such as lane-changing, acceleration, deceleration, etc., the fixed model cannot provide long-term constraints on cumulative errors, resulting in a decrease in fusion positioning accuracy and stability. Therefore, this paper proposes a multimodal fusion positioning method with adaptive driving behavior for intelligent vehicles. First, to adapt to multimodal driving behavior, a multimodal assisted positioning physical model with adaptive driving behavior (MAPM) is established, which expresses different physical models probabilistically based on driving behavior and historical data. Secondly, high-precision estimation of vehicle positioning parameters is achieved based on model probability and interactive multi-model (IMM). Finally, effective fusion of MAPM/GNSS/INS positioning information is achieved under the federated Kalman filtering framework. The simulation results show that compared to traditional GNSS/INS fusion positioning, the proposed method can effectively improve positioning accuracy and stability, especially in driving conditions with changes in driving behavior.
From the Midtown Manhattan Study to the Epidemiologic Catchment Area Study: the advent of mechanical objectivity in psychiatry
Authors: Demazeux Steeves
Published: December 2023

In this paper I compare the methodology of two of the most famous epidemiological studies: The Midtown Manhattan Study (1952–60) and the Epidemiologic Catchment Area Study (1980–5). At first sight, there are few features that distinguish them; both were studies of large samples of the general population; they both used highly sophisticated methods of data analysis and standardized instruments; and they involved interviewers who were not professional clinicians. However, if we carefully compare the protocols that define how ‘clinical’ information is collected, we realize that some important changes in methodology were not only due to practical necessities, but also involved an important transformation in the role of the interviewer and the skills traditionally associated with the clinician.
Guidelines for Using Simulations in Qualitative Research on Social Work Practice Competencies

Published: December 2023

The use of simulation (i.e., trained actors) has gained much attention in social work as a method of teaching, learning, and student assessment. Simulation has also been used in medicine as a research method in studying practice competencies. The use of simulation as a part of research design is relatively new in social work. Particularly, little is known about how simulations can be combined with well-established qualitative research methods. We posit that simulation can further advance qualitative research on social work practice, which requires a highly complex set of skills that are procedural, cognitive, affective, and relational. Drawing from two study examples, we propose guidelines for how simulations can be incorporated in qualitative research on complex practice competencies essential for enhancing the quality of health and social services.
Ten-Year Minimum Follow-up Study of First Metatarsophalangeal Joint Fusion in Young vs Old Patients
Authors: Scheurer Fabrice , Zimmermann Stefan M. , Fischer Philipp , Wirth Stephan H. , Beeler Silvan , Viehöfer Arnd F.
Published: December 2023

Background:

Painful degenerative joint disease (DJD) of the first metatarsophalangeal joint (MTP I), or hallux rigidus, mainly occurs in later stages of life. For end-stage hallux rigidus, MTP I arthrodesis is considered the gold standard. As young and active patients are affected considerably less frequently, it currently remains unclear, whether they benefit to the same extent. We hypothesized that MTP I arthrodesis in younger patients would lead to an inferior outcome with decreased rates of overall with lower rates of patient postoperative pain and function compared to an older cohort.

Methods:

All patients aged <50 years who underwent MTP I arthrodesis at our institution between 1995 and 2012 were included in this study. This group was then matched and compared with a group of patients aged >60 years. Minimum follow-up was 10 years. Outcome measures were Tegner activity score (TAS), a “Virtual Tegner activity score” (VTAS), the visual analog scale (VAS), and the Foot Function index (FFI).

Results:

Sixty-one MTP I fusions (n = 28 young, n = 33 old) in 46 patients were included in our study at an average of 14 years after surgery. Younger patients experienced significantly more pain relief as reflected by changes in VAS and FFI Pain subscale scores. No difference in functional outcomes was found with change in the FFI function subscale or in the ability to have desired functional outcomes using the ratio of TAS to VTAS. Revision rate did not differ between the two groups apart from hardware removal, which was significantly more likely in the younger group.

Conclusion:

In patients below the age of 50 years with end-stage DJD of the first metatarsal joint, MTP I arthrodesis not only yielded highly satisfactory postoperative results at least equal outcome compared to an older cohort of patients aged >60 years at an average 14 years’ follow-up. Based on these findings, we consider first metatarsal joint fusion even for young patients is a valid option to treat end-stage hallux rigidus.

The Expert Panel for Cosmetic Ingredient Safety (Panel) assessed the safety of 5 trialkyl trimellitates. These ingredients, which are all structurally related as alkyl esters of trimellitic acid, are reported to function in cosmetics as skin conditioning agents; 2 of the ingredients are also reported to function in cosmetics as plasticizers. The Panel reviewed the available data to determine the safety of these ingredients, and concluded that the trialkyl trimellitates are safe in the current practices of use and concentration when formulated to be non-irritating.
The models of co-teaching and a spectrum for assessing collaboration: Examining English language co-teaching practices in South Korea
Authors: Kim Sung-Yeon , Moodie Ian
Published: December 2023

Many countries have developed co-teaching programs pairing native-English-speaking teachers with local English teachers. Despite the optimistic aims of these programs, research has revealed challenges for co-teaching, such as with teachers’ contrasting belief systems or cultural differences. However, research has yet to examine the models of co-teaching applied and the extent of collaboration observed with multiple co-teaching pairs across different teaching contexts as is done in the present study. The study uses qualitative analysis, aiming to examine the approaches to co-teaching and the degree of collaboration with 14 pairs of co-teachers across different school levels (primary, middle, and high schools) in South Korea. Based on classroom observations and interview data, the study found that of seven models of English-language co-teaching (one teaching / one assisting, team teaching, one teaching / one assessing, parallel teaching, alternative teaching [pre-teaching], alternative teaching [re-teaching], and station teaching), the one teaching / one assisting model was prevalent for 10 dyads and the team-teaching model for four dyads. The other models of coteaching were not used or reported to be used by these participants. In addition, by focusing on the observed and stated practices of these participants, the study adds to the literature by showing how co-teaching collaboration occurs across a spectrum, from no collaboration to full collaboration, with differing levels of engagement throughout. The study suggests that this proposed spectrum will be useful for researching and assessing co-teaching practices, and it implies that the efficacy of co-teaching could be increased by supporting fuller collaboration and multiple approaches to co-teaching beyond the dominant one teaching / one assisting model.

Bullying is one of the most common forms of youth violence and is associated with myriad adverse consequences over the life course. There has been increasing interest in examining whether anti-bullying legislation is effective in preventing bullying victimization and its negative effects. However, a lack of data structures that comprehensively and longitudinally assess anti-bullying legislation and its provisions has hampered this effort. We provide 18 years of data (1999–2017) on anti-bullying legislation and amendments across 50 U.S. states and the District of Columbia, which we are making publicly available at LawAtlas.org. This article describes how the legal content analysis was conducted, provides information on the reliability of the coding, and details provisions of the legislation that were coded, such as funding provisions and enumerated groups (a total of 122 individual codes are provided). Over 90% of states had at least one amendment to their legislation during this 18-year period (range: 0–22; Mean = 6.1), highlighting both the evolving content of anti-bullying statutes and the importance of tracking these changes with longitudinal data. Additionally, we offer illustrative examples of the kinds of research questions that might be pursued with these new data. For instance, using survival analyses, we show that a variety of state characteristics (e.g., political leaning of state legislatures) predict time to adoption of key provisions of anti-bullying legislation (e.g., the comprehensiveness of legal provisions). Finally, we end with a discussion of how the dataset might be used in future research on the efficacy of anti-bullying legislation.
Risk factors for neonatal VAP: A retrospective cohort study
Authors: Dang Jiawen , He Lijuan , Li Cheng
Published: December 2023

Ventilator-associated pneumonia (VAP) is a serious complication in neonates requiring mechanical ventilation. This study aimed to determine the risk factors associated with the development of VAP in neonates admitted to the neonatal intensive care unit (NICU) of the Affiliated Hospital of Southwest Medical University. In a retrospective observational study, neonates admitted to the NICU from 1 January 2019, to 31 December 2021, requiring ventilation for more than 48 h were included. Neonates who died within 48 h of NICU admission, those without obtainable consent, or identified with a genetic syndrome were excluded. Various neonatal and clinical variables were evaluated. Univariate and multivariate analyses were performed to determine risk factors associated with VAP. Of the total neonates included, several risk factors were identified for VAP, such as being a premature infant and use of dexamethasone and sedatives. Moreover, reintubation was found to decrease the risk of VAP. Some factors like gestational age, birth weight, Apgar scores at 5 min, and other parameters were found not significantly associated with the development of VAP. The study identified several risk factors associated with the development of VAP in neonates. Recognizing these risk factors could help in the prevention and early management of VAP, thus improving the prognosis for these patients. Further studies are needed to validate these findings and explore the mechanistic links between these factors and VAP.
Healthcare Workers’ Adherence and Attitudes Toward the Adherence to COVID-19 Precautionary Guidelines Post-Vaccination: A Cross-Sectional Pilot Study
Authors: Abu-Alhaija Dania M. , Gillespie Gordon Lee
Published: December 2023

Background:

Healthcare workers (HCWs) have shown increased adherence to infection control practices during the COVID-19 pandemic. However, there is a need to assess their adherence to and attitude toward COVID-19 guidelines after being vaccinated. The purpose of this pilot study is to assess the adherence to and attitudes toward the adherence to COVID-19 guidelines among HCWs who have been vaccinated.

Methods:

A retrospective cross-sectional design was employed. One hundred and eight participants were recruited via email from a medical center in the Midwest United States. The participants completed online surveys measuring the level of adherence to and attitudes toward the adherence to COVID-19 guidelines. The response rate was 5.4%.

Findings:

Most participants were female (73.1%) and white (82.4%). The participants adhered to COVID-19 guidelines 79.7% of the time. The most frequently followed guidelines were performing hand hygiene, wearing a respirator or well-fitting mask in areas where patients may be present, and wearing eye protection when entering the room for a patient with suspected or confirmed COVID-19 infection. The least performed precautions were performing COVID-19 testing after exposure to a suspected or confirmed COVID-19 case and maintaining social distancing. There was a significant decrease in the perceived importance of adherence to COVID-19 precautions post-vaccination ( p <.001, 95% CI [−0.78, −0.35]).

Conclusions:

The increased perception of safety after receiving COVID-19 vaccination may negatively influence HCWs’ adherence to COVID-19 precautionary guidelines. Continuous education and monitoring of HCWs’ safety practices are important to influence HCWs’ attitudes to adhere to COVID-19 precautions, particularly after vaccination.
The For-Profit Side of Public U: University Contracts with Online Program Managers
Authors: Hamilton Laura T. , Daniels Heather , Smith Christian Michael , Eaton Charlie
Published: December 2023

Online enrollments in public universities have soared, in part because of universities’ increasing reliance on for-profit online program managers (OPMs) for everything from instructional design to student recruitment. However, scholarship has indicated that OPMs may play a role in producing predatory forms of inclusion in higher education for marginalized students. To identify mechanisms through which this might occur, the authors conduct a mixed-methods analysis of 161 contracts between OPMs and two- and four-year public universities, an original database of third-party financing structure, and university webpages. The analysis identifies several contract features—targeting, extraction, opacity, and captivity—that may help concentrate marginalized students in extractive or exploitative online programs at public universities. The authors also show that OPMs funded by private equity or venture capital are most likely to include contract features that incentivize aggressive revenue production and promote the recruitment of marginalized students in online, but not in-person, programs.
