Published: July 2022

Aim of study: To investigate the impact of allochthonous material from piscivorous birds on forest soil microarthropod communities. Area of study: Six study zones in the Curonian Spit peninsula (western Lithuania) were designated in Pinus sylvestris stands with nesting sites of the great cormorants, taking into account the relief and the duration of the ornithogenic impact. Materials and methods: The total abundance of mites and Collembola and the species richness and diversity of Oribatida and Gamasina mites were assessed and compared. Main results: The abundance of Collembola, Tarsonemidae and Acaridae mites positively correlated with ornithogenic activity, while Oribatida and Gamasina mites decreased significantly. The structure of microarthropod communities was similar in most of the studied zones, except for the active nesting zone and the abandoned part of the colony on the dune slope. The greatest species richness of Oribatida and Gamasina was found in the unaffected forest in the dune hollow, whereas the lowest value was found in the active nesting area and in the abandoned part of the colony on the dune slope. Of the environmental parameters studied, soil pH (r = - 0.725) and tree layer (r = 0.827) were those most significantly related to the changes of microarthropod communities. Research highlights: We found that cormorant colonies have a strong impact on forest ecosystems and soil properties, leading to significant changes in soil microarthropod communities. Birds thus create a natural disturbance experiment that can help reveal the factors that determine the diversity and composition of natural microarthropod communities.

Published: July 2022

Introduction:

Total joint arthroplasty (TJA) volume and the number of orthopaedic surgeons in the United States have increased in recent years, but local growth variation has not been studied. This study assesses recent changes in state-level distribution of orthopaedic surgeons in the United States and corresponding local trends in TJA volume.

Methods:

Data from the National Inpatient Sample database (2000 to 2014) were reviewed. Urban versus rural setting and teaching versus nonteaching hospitals were identified among TJA procedures for comparison. Data from the American Academy of Orthopaedic Surgeons (2002 to 2016) detailing orthopaedic surgeon practice location were evaluated, and linear regression analysis was used to correlate state population data with orthopaedic surgeon density.

Results:

From 2000 to 2014, there was a 0.1% to 0.3% (P < 0.01) annual decrease in the proportion of TJA procedures conducted in rural hospitals. No notable change was observed in the proportion of TJA procedures conducted at urban teaching versus nonteaching hospitals. Linear regression analysis demonstrated that decreased state population was associated with higher orthopaedic surgeon density (adjusted R2 = 0.114, P < 0.01). States with a higher percentage of population living in rural areas had a lower density of orthopaedic surgeons in the South region and a higher density of orthopaedic surgeons in the remainder of the county.

Conclusions:

Less populated, rural states have a higher density of orthopaedic surgeons than states with increased population and less rural areas. Although TJA volume has increased since 2000, the proportion of TJA procedures conducted at rural hospitals has decreased. No change was found in the proportion of TJA procedures conducted at urban teaching versus nonteaching hospitals. This may indicate that more patients living in rural areas are seeking TJA care in urban centers. Future studies are needed to confirm this and ensure that patients living in rural areas have appropriate access to TJA care.

Authors: Zhang Beifan
Published: July 2022

Based on Green Credit Guidelines released in 2012, this paper analyzes the impact of green credit policy on green innovation of heavy polluters by difference-in-differences model (DID) with data of Chinese A-share listed companies from 2008 to 2019 as a sample. It is found that after the implementation of green credit policy, the green innovation of heavy polluters is significantly inhibited compared to non-heavy polluters and fails to exert the Porter effect. Further studies find that there is heterogeneity in the impact of green credit policy on green innovation of heavy polluters: Compared with green utility patent, green credit policy significantly inhibits green invention patents of heavy polluters. Compared with state-owned enterprises, green credit policy significantly inhibits green innovation of the non-state-owned. Compared with eastern region, green innovation of heavy polluters in central and western region is more inhibited by the policy. This paper further expands and extends the research on the effect of green credit, which has important implications for the corporate green transformation and green development of economy under the green credit policy.

Authors: Wang Zhaoyue
Published: July 2022

In recent years, an increasing number of scholars have begun to notice the relationship between leader-member exchange and employees’ innovative behavior and organizational citizenship behavior. However, few studies have focused on the underlying mechanism of leader-member exchange affecting innovative behavior and organizational citizenship behavior. This study aims to explain the effects of leader-member exchange on employees’ behavior from the perspective of individual psychological experience, based on social exchange theory, conservation of resources theory, and social cognitive theory. The study included 298 papers containing 321 effect sizes and 103,615 research samples for meta-analysis, and found that: (1) leader-member exchange is significantly and positively related to innovative behavior, organizational citizenship behavior, and thriving at work; (2) leader-member exchange can facilitate individuals to exhibit more innovative behavior and organizational citizenship behavior by enhancing thriving at work; (3) collectivist cultural tendency tends to play a moderating role in the process of leader-member exchange influencing individual innovative behavior and organizational citizenship behavior through thriving at work. Compared to the context of low collectivist cultures, the effects of leader-member exchange on thriving at work are stronger in the context of high collectivist cultures, so are the indirect effects of leader-member exchange on innovative and organizational citizenship behavior through thriving at work. The findings help to understand the underlying mechanism and boundary conditions of leader-member exchange affecting individual psychological experiences and behavior. They also provide momentous practical insights for managers to build high-quality exchange relationships with employees and enhance organizational collectivism to promote innovative and organizational citizenship behavior.

In recent years, in pursuit of higher returns, people began to try the combination of bitcoin and gold. This study explored how to use the current and past prices of gold and bitcoin to get the best investment strategies for the next day to get the maximum return. The obtained historical price data of gold and bitcoin from 2016 to 2021 are divided into three stages according to the time axis, namely, stage Ⅰ (1st day-300th day), stage Ⅱ (300th day-400th day) and stage III (400th day-1825th day). Different methods are used for each stage to determine the trading strategy. In stage I, a comprehensive index is constructed by using four technical indexes closely related to the formulation of daily strategies in the financial market, such as moving average convergence and divergence, deviation rate, stochastic index and detrended price oscillator, and the trading strategy is determined by using this comprehensive index. In stage II, the four technical indicators and product prices in stage I are used as training sets, and the daily trading strategy is given by using the decision tree classification model. In the third stage, the long-term and short-term memory neural network is used to develop the future price prediction model of gold and bitcoin, and the trading strategies of gold, bitcoin and cash asset portfolios are formulated according to the dynamic optimization results of different types of traders' risk tolerance. The results show that during the five years from September 11, 2016 to September 10, 2021, the whole strategy created a net profit of $170,381 for aggressive traders and $7,694 for rational traders.

Negative Transfer of Grammar in Chinese Students’ English Learning
Authors: Cai Wenbo
Published: July 2022

In the present Chinese society, the population of second language learning students, especially English learners, is increasing due to the tendency of globalization. Because of different cultural backgrounds and language patterns, it is common for students to make grammar mistakes under the effect of negative transfer. Negative transfer in grammar can be divided into several features, including subject-verb disagreement, tense error, nouns and plural form error, incorrect use of prepositions, incorrect word collocation, and error in word order. The study of negative transfer is helpful to the development of English learning and English education. Therefore, this study reviews the Negative Transfer of Grammar in Chinese Students’ English Learning. The main findings include 1) subject-verb disagreement: grammatical disagreement, meaning disagreement, and proximity disagreement, in which grammatical disagreement is caused by negative transfer. 2) tense error: verb transformation errors and sentence structure errors. 3) nouns and plural form error: errors of “s” using and the misjudgment of the singular or plural of the subject. 4) incorrect use of prepositions: errors caused by prepositions that have the same meanings in Chinese but are distinguished more strictly in English. 5) incorrect word collocation: errors caused by cultural differences. People from different cultural backgrounds tend to be influenced by the word composition of their first language.  6) error in word order: introduces more complicated sentence structure that leads to errors, including transformation between statement and general question and place of adverb.

Authors: Ardiles Rodrigo , Alfaro Paola , Moya María , Leyton Claudia , Rojas Patrick , Videla Jeremy
Published: July 2022

Los futuros profesionales de enfermería requieren de una formación integral que incluya aspectos teóricos y el desarrollo de habilidades emocionales. Estas últimas, hacen referencia al desarrollo de la Inteligencia emocional, la cual, según las investigaciones de la última década, tendría una relación con un mejor ajuste a las exigencias del medio universitario y/o laboral. El objetivo de esta investigación fue relacionar los niveles de inteligencia emocional con los niveles del Síndrome de Burnout y Engagement académico en estudiantes de enfermería de una Universidad del norte del país, por medio de un estudio cuantitativo, correlacional, no experimental, transversal. La muestra fue de 189 alumnos de enfermería, de ambos sexos, cursando entre el primer y octavo semestre de la malla académica, donde se realizó un muestreo probabilístico aleatorio. Los resultados evidenciaron correlación entre los factores de claridad y regulación emocional con ambos factores de Engagement (predisposición y satisfacción). Por otro lado, al correlacionar inteligencia emocional con Burnout académico, se evidenció, que el único factor que correlacionó con las 3 dimensiones de Burnout fue regulación emocional. Además, se demostró que a mayor claridad emocional menor sería el agotamiento y mayor la realización personal. Finalmente, se mostró que mayores niveles de Burnout correlacionaron con menores niveles de satisfacción con los estudios.

Entrepreneurial activities are not only a means for social empowerment but also, empowering them economically and enable them to contribute more to overall development. The present study was investigated in the year 2014-2015 in Bagalkot, Vijayapur and Uttar Kannada districts of North Karnataka of India. A sample of 50 trained and 50 untrained respondents were selected from each of the three districts making a total sample of 300 with ex-post facto research design. Majority of the trained (58.67 %) and untrained (66.67 %) entrepreneurs belonged to middle age group, educated upto middle school, married and are from rural background with low-income level. As per RUDSETI guidelines the enterprises have been classifi ed as agriculture, product, process and general enterprises. Majority of the trained (50.66%) and untrained (62.00%) entrepreneurs had taken up product based enterprises. Maximum number (70.00 %) of trained entrepreneurs availed loan from banks while, maximum number of untrained entrepreneurs (63.34 %) borrowed money from money lenders. The highest success rate was for Bagalkot (76.45 %) followed by Vijayapur (64.64 %) and Uttar Kannada (53.80 %). Thirty-two per cent of trained entrepreneurs had started their enterprise between four to six months after taking the training from the institute.

Authors: Khan Khurram , Patel Priyal , Phan Kari , Love Ebony
Published: July 2022

Fluoroquinolones are a class of antibiotics that are commonly used to treat gram-negative and gram-positive bacterial infections. Tendinopathies, most commonly affecting the Achilles tendon, are a possible side effect with the use of Fluoroquinolones. Tendinopathies may occur from two hours to six months upon starting a course of fluoroquinolones. This case study presents a patient who had a magnetic resonance imaging (MRI) confirmed peroneus longus tendon rupture with the presence of an os peroneum fracture after two courses of ciprofloxacin treatment, one course five months prior to the injury and the second course one month prior to the injury. Physicians and patients should monitor for tendon soreness and pain in the peroneus longus tendon in addition to the classically documented Achilles tendon following the use of fluoroquinolones.

Authors: Lin Tzu Lu , Shaw Tracie , Mirasol Evyn , Hawkins Brandon
Published: July 2022

Tibial sesamoidectomy is frequently the treatment of choice for different tibial sesamoid pathologies when non-surgical treatment fails. However, surgery is not without postoperative complications, such as hallux abducto valgus (HAV) deformity. Currently, there is a paucity of research regarding isolated tibial sesamoidectomy and its complications. The purpose of this paper is to present two cases of isolated tibial sesamoidectomy, a brief description of surgical technique, an anatomic and functional description of hallux sesamoids, and an updated literature review on isolated tibial sesamoidectomy.

Authors: Calabrese Julia E. , Capraro Mary Margaret , Thompson Christopher G.
Published: July 2022

Problem posing research in mathematics education has increased in the last decade. As a result, the intent of the present study is to examine and summarize the research that has been conducted. Specifically, we examined articles published from 2011–2020 that studied the impact of problem-posing instruction on students’ problem-solving abilities. In total, seven articles were included in the systematic review. We concluded that the effect of problem-posing instruction on students’ problem-solving skills is varied, though prior research on the relationship between posing and solving demonstrates a positive impact. Thus, while there remains a great need for further research in this area, there are indications that problem-posing could improve students’ problem-solving abilities.
Design and development of montmorillonite-sodium alginate microbeads for oral sustained delivery of cefaclor
Authors: Singh Shivani
Published: July 2022

Drug administration via oral route is most suitable for drug delivery to patients. But this route is associated with several drawbacks such as high frequency of administration as well as gastric discomfort. To avoid these problems attempt was made to develop the sustained release system by using nanocomposite clay (MMT) and polymer (Na-Al) based microbeads for oral administration of CFR. The formulations were optimized and validated by using Box–Behnken design with 3 different levels of MMT, Na-Al and CaCl2 wherein the %EE and % drug release at 8 h were considered as dependent responses. The developed formulation was characterized by FT-IR, DSC as well as XRD. The optimized formulation was evaluated for % yield, swelling behavior, particle size, drug release and surface morphology by FESEM. The developed formulation showed physical interaction due to surface adsorption and intercalation of drug with that of MMT. The optimized formulation showed high yield, %EE and swelling behavior due to high amount of MMT and Na-Al. The particle size of the microbeads was below 500 µm and drug release takes place in sustained manner up to 12 h. Polymeric cross-linking and MMT stalking were observed in FESEM study indicated distinctive system. Drug release follow the non-fickian diffusion pattern coupled with matrix release as indicated by Korsemeyer-Peppas (n) value 0.72.

Published: July 2022

Marfan syndrome classically presents with aortic root aneurysms. Aortic ectasia causes diverse blood flow alterations, influencing the behavior of coagulation factors and platelet activity. Heparin resistance has also been reported associated with Marfan Syndrome in a small number of patients, probably due to antithrombin III (ATIII) deficiency or various mutations. The ascending aorta and the aortic valve are replaced with prosthetic material during Bentall- de Bonno procedures. Resistance to anticoagulation during extracorporeal circulation, represents a significant challenge for both anesthesiologists and the surgical team. Resistance to heparin was observed in a patient with Marfan syndrome undergoing a Bentall procedure. ATIII concentrate was not available, and ACT did not increase despite high doses of heparin. An alternate anticoagulation approach was used successfully.

يُعد الأمن السيبراني من أكثر المسائل اهمية في حياتنا المعاصرة بحكم علاقته المباشرة بجميع مجالات الحياة العامة من سياسة واقتصاد وامن وثقافة وغيرها، وتعتمد عليه معظم دول العالم في مؤسساتها الرسمية وغير الرسمية لا سيما في بنيتها التحتية، وان الاهتمام به وتلافي نقاط الضعف تعد من اولويات الأمن الوطني لأية دولة، وتمثل الحرب السيبرانية الجيل الخامس من التطور المعاصر للحروب وأكثرها خطورة بحكم الاضرار الكبيرة التي تخلفها في البنية التحتية لأية دولة، وما يترتب عليه من مساس مباشر لحياة المواطنين. وأصبح العراق لاسيما منذ العام 2003 بسبب الانفتاح على العالم والتطور في المجال التقني والمعلوماتي أكثر عرضة للهجمات السيبرانية.
The purposes of elections in countries after ethnic conflicts
Authors:   Ministry of Higher Education and Scientific Research - Iraq, Saleh Ali Lecturer . Dr. Khalaf
Published: July 2022

Elections in post-ethnic conflict countries have goals that they seek to achieve and limit the effects of violent extremism against an ethnically different one. Establishing the foundations for peaceful coexistence between social components, achieving political stability, and the peaceful rotation of power are the purposes of the electoral mechanism in countries that suffer from conflicts on ethnic grounds. The post-conflict phase needs new mechanisms to remove all causes of conflict or limit their effects, and in this case we need fair elections, independent administration and transparent mechanisms that limit the conflict of ethnic identities, sectarian polarizations and atonement. From all this the research aims to analyze the purposes of the elections and determine the most important ones to reach to the peaceful coexistence of social components to build sustainable peace in Iraq
