Effect of Virtual Reality on Functional Ankle Instability Rehabilitation: A Systematic Review
Authors: Lin Hongyuan , Han Kaiyue , Ruan Bing
Published: November 2021

Objective. To systematically evaluate the effectiveness of virtual reality (VR) in the rehabilitation of patients with functional ankle instability (FAI). Methods. Nine databases were researched, including PubMed, Cochrane Library, Web of Science, Embase, OVID, CNKI, VIP, WanFang, SinoMed, ResearchGate, and WorldWildScience. The publication date deadline was May 22, 2021. To analyze the effect of VR rehabilitation of FAI, we systematically reviewed the literature using the RevMan 5.4 software. Main Results. Five randomized controlled trials (RCTs) were included in the analysis, consisting of 137 patients with FAI; 68 of them were in the experimental group, 69 were in the control group, and all were university students. A comparison study was conducted between the two groups in terms of balance function, muscle performance, and proprioception. VR rehabilitation in the treatment of FAI was found to be significantly more effective using a 30-second single-leg standing test than conventional rehabilitation. The angular offset index of VR rehabilitation training was significantly lower than that of conventional balance training (0.66 ± 0.18 vs. 0.95 ± 0.21;

P

 = 0.005). Conclusion. VR rehabilitation is effective at treating FAI. However, RCTs with higher homogeneity are needed to provide a more reliable evidence-based foundation for clinical rehabilitation.
Ultrasound Elastography under Deep Learning Algorithm to Analyze the Therapeutic Effect of Clustered Regularly Interspaced Short Palindromic Repeats Short Hairpin Ribonucleic Acid Nanoparticles on Cervical Cancer
Authors: Li Minghui , Li Weiwei , Zhao Liang
Published: November 2021

This study aimed to analyze the effect of the deep learning algorithm on ultrasound elastography on the treatment of cervical cancer with clustered regularly interspaced short palindromic repeats (CRISPR) short hairpin ribonucleic acid (shRNA) nanoparticles, aiming to provide a reference for the clinical application of deep learning to analyze the therapeutic effect of the disease. In this study, CRISPR and shRNA plasmid nanoparticle drugs were used to treat 55 patients with cervical cancer in the experimental group, and normal saline was injected to another 53 patients in the control group, so compare the effect of nanoparticles in the treatment of cervical cancer. Professional doctors and the recurrent neural network (RNN) intelligent algorithm were used to score cervical cancer based on the ultrasound elastograph images by taking blue, green, and red (BGR) as diagnosis criteria. As a result, the experimental group had a total of 217 points before drug administration and a total of 224 points after drug administration. Each patient had an average increase of 0.13 points. The control group had a total of 200 points before drug administration and a total of 223 points after drug administration, and each patient had an average increase of 0.43 points. The experimental group was obviously different from the control group (

P
<
0.05

). Each tissue image output by the RNN was clearer than the original image, and the score given by intelligent calculation was faster than that of professional doctors. The monitoring effect of the deep learning RNN intelligent algorithm on the therapeutic effect of nanomedicine was analyzed. It was found that the average accuracy of the experimental group and the control group was 98.95% and 90.34%, respectively; and the experimental group was greatly different from the control group (

P
<
0.05

). In short, nano-CRISPR and shRNA drugs had remarkable effects on the treatment of cervical cancer, and the scores given by the deep learning intelligent algorithm were faster and more accurate, which provided theoretical guidance for the clinical application of deep learning algorithms to analyze the treatment effects of diseases.
Parabolic Detection Algorithm of Tennis Serve Based on Video Image Analysis Technology
Authors: Tang Hongxin
Published: November 2021

At present, the existing algorithm for detecting the parabola of tennis serves neglects the pre-estimation of the global motion information of tennis balls, which leads to great error and low recognition rate. Therefore, a new algorithm for detecting the parabola of tennis service based on video image analysis is proposed. The global motion information is estimated in advance, and the motion feature of the target is extracted. A tennis appearance model is established by sparse representation, and the data of high-resolution tennis flight appearance model are processed by data fusion technology to track the parabolic trajectory. Based on the analysis of the characteristics of the serve mechanics, according to the nonlinear transformation of the parabolic trajectory state vector, the parabolic trajectory starting point is determined, the parabolic trajectory is obtained, and the detection algorithm of the parabolic service is designed. Experimental results show that compared with the other two algorithms, the algorithm designed in this paper can recognize the trajectory of the parabola at different stages, and the detection accuracy of the parabola is higher in the three-dimensional space of the tennis service.

Published: November 2021

So far, diabetes mellitus has become a health threat to society all over the world. Especially, people with diabetes have always coped with complications related to this disease and unexpected side effects of synthetic drugs. Thus, there has been a current trend for researchers to find out new natural ingredients which were safer and still effective in the treatment of diabetes. Gomphogyne bonii Gagnep. extract (G. bonii extract) was an herbal-derived product of the Pharmacy Department, Vietnam University of Traditional Medicine. This study was designed to assess the antidiabetic effect of G. bonii extract on a high-fat diet (HFD) and alloxan-induced diabetes in mice. Mice were first fed a high-fat diet for 8 weeks and then given an intraperitoneal injection of alloxan (ALX) at the dose of 180 mg/kg b.w. After the diabetic mice model was successfully established, mice were administered orally with G. bonii extract at two doses of 4 mL/kg b.w/day and 12 mL/kg b.w/day for 2 weeks. The results revealed that G. bonii extract at both doses ameliorated the effects of ALX on the concentration of glucose, total cholesterol (TC), triglyceride (TG), and low-density lipoprotein-cholesterol (LDL-C) and microhistological images of livers. Besides, the antidiabetic effect of G. bonii extract at the dose of 12 mL/kg b.w/day was better than that at the dose of 4 mL/kg b.w/day. This suggested that G. bonii extract could be a potential agent for treating diabetes mellitus in clinical practice.

Authors: Qiao Peng , Xu Jie , Liu Xueni , Li Xuehan
Published: November 2021

Objective. To illustrate the role of tanshinone IIA (TSN) in regulating cardiac structure and function following myocardial infarction (MI) and the involvement of miR-205-3p in TSN-induced antifibrosis effect on ventricular remodeling. Patients and Methods. One hundred MI patients were randomly assigned into two groups, and they were treated with TSN (TSN group,

n
=
50

) or conventional therapy (control group,

n
=
50

). Plasma levels of miR-205-3p and TGF-β1 were detected in each patient. Echocardiography was conducted in each patient at post-MI 1 day, 2 weeks, and 4 weeks, respectively, for recording LVIDd (left ventricular internal-diastolic diameter), LVIDs (left ventricular internal-systolic diameter), and LVEF (left ventricular ejection fraction). The interaction between miR-205-3p and TGF-β1 was examined by the RNA-Binding Protein Immunoprecipitation (RIP) assay. After induction of TGF-β1 and/or 10 μL of TSN in cardiac fibroblasts, relative levels of miR-205-3p, Col1a1, and Col3a1 were detected by quantitative real-time polymerase chain reaction (qRT-PCR). Results. Compared with the control group, miR-205-3p and TGF-β1 were downregulated in plasma of MI patients in the TSN group. In the TSN group, LVIDd and LVIDs were reduced, and EF was enhanced at 2 weeks and 4 weeks compared with that at post-MI 1 day. miR-205-3p could negatively interact with TGF-β1. TSN induction abolished the regulatory effects of TGF-β1 on downregulating miR-205-3p and upregulating Col1a1 and Col3a1 in cardiac fibroblasts. Conclusions. Through upregulating miR-205-3p and downregulating TGF-β1, TSN alleviates cardiac fibrosis and improves ventricular remodeling following MI.
Retrospection of the Optimization Model for Designing the Power Train of a Formula Student Race Car
Authors: Kumar M. Naveen , Jagota Vishal , Shabaz Mohammad
Published: November 2021

This article describes the power train design specifics in Formula student race vehicles used in the famed SAE India championship. To facilitate the physical validation of the design of the power train system of a formula student race car category vehicle engine of 610 cc displacement bike engine (KTM 390 model), a detailed design has been proposed with an approach of easing manufacturing and assembly along with full-scale prototype manufacturing. Many procedures must be followed while selecting a power train, such as engine displacement, fuel type, cooling type, throttle actuation, and creating the gear system to obtain the needed power and torque under various loading situations. Keeping the rules in mind, a well-suited engine was selected for the race track and transmission train was selected which gives the maximum performance. Based on the requirement, a power train was designed with all considerations we need to follow. Aside from torque and power, we designed an air intake with fuel efficiency in mind. Wireless sensors and cloud computing were used to monitor transmission characteristics such as transmission temperature management and vibration. The current study describes the design of an air intake manifold with a maximum restrictor diameter of 20 mm.

Published: November 2021

Synovial sarcoma (SS) is a rare malignant mesenchymal tumor that mainly occurs in body extremities, being uncommon in the head and neck region. In the present study, we described a case of primary intraosseous SS arising in the mandible of a 22-year-old young male. The patient reported a painful swelling on the left side of the mandible for the last 7 months. Imaging exams showed the presence of an expansive and multilocular radiolucent lesion, extending from the left condyle to the mandibular body. The clinic diagnostic hypotheses were ameloblastoma or malignant neoplasm. Histologically, the lesion was characterized by a proliferation of spindle cells exhibiting vesicular nuclei and evident nucleolus. Neoplastic cells were positive for AE1/AE3, cytokeratin 7, vimentin, CD-99, and TLE-1 and negative for CD-34, S-100, SMA, and HHF-35. A combination of clinical, histologic, and immunohistochemical characteristics supported the diagnosis of SS. The patient was referred for treatment, and preoperative exams did not reveal any other tumor foci in the body of the patient. The final diagnosis was of a primary intraosseous SS of the mandible.
Intravascular Basal Cell Carcinoma Hiding under a Keratoacanthoma
Authors: Dunn Austin , Kleinfelder Raymond E. , Glick Brad P.
Published: November 2021

A 79-year-old male presented for removal of what was proven to be a keratoacanthoma. Additional tissue removed deep to the initial lesion revealed intravascular basal cell carcinoma (BCC). Intravascular BCC is exceedingly rare with only 8 cases previously reported in the literature. Intravascular BCC may be associated with more aggressive subtypes. Intravascular infiltration is more common in metastatic BCC, but this finding may not imply causality. More data are required in order to determine prognostic implications of intravascular BCC and to develop a protocol for managing patients with this unique finding.
Navigating Challenges in Monitoring Chronic Myeloid Leukemia with Multiple BCR-ABL1 Transcripts
Authors: Smith Brittany M. , Brewer Diana , Druker Brian J. , Braun Theodore P.
Published: November 2021

Quantitative PCR-based strategies are typically effective for monitoring BCR-ABL1 transcript levels in chronic myeloid leukemia (CML). Additionally, some patients treated with tyrosine kinase inhibitors can experience long-term treatment-free remission after discontinuation of the inhibitor. However, this outcome hinges on effectively monitoring the patient’s response to therapy. We present a patient with CML and multiple BCR-ABL1 transcripts, including a rare isoform that lacks qPCR standardization. We describe unexpected discrepancies in transcript quantification, further having an impact on clinical decision-making regarding duration of treatment. To better inform clinical practice, we suggest monitoring patients at the same testing facility to better track transcript trend.

This Precious Human Life
Authors: Simonds Colin H.
Published: November 2021

This paper analyzes the idea of “human exceptionalism” from the perspective of Tibetan Buddhism. It argues that, in the Tibetan Buddhist context, many of the negative consequences of human exceptionalism are overshadowed by the concept’s ability to promote an altruistic comportment to the more-than-human world when supported by the Buddhist ontology and its broader project of liberating all beings from duhkha. To this end, this paper looks at how Tibetan Buddhist teachers qualify a “precious human life” by conducting a close reading of primary texts before extrapolating some general themes of these selected passages and applying them to our contemporary ecological situation. In doing so, it makes the argument that human exceptionalism is not a problem in and of itself but has a positive or negative effect on the more-than-human world depending on how it is established, maintained, and understood. It also demonstrates how Tibetan Buddhism can be a useful tradition for thinking alongside as we attempt to address global issues concerning the environment and nonhuman animals.
Birds as Dads, Babysitters, and Hats
Authors: Berkowitz Beth A.
Published: November 2021

The commandment to send the mother bird from her nest before taking her eggs or chicks, known in Jewish tradition as shiluach hakan, is found in Deuteronomy 22:6–7. This essay addresses dominant perspectives on the mother bird mitzvah—its association with good luck, bad luck, and compassion—before showcasing rabbinic texts from Mishnah and Babylonian Talmud Hullin Chapter 12 that evince interest in birds as ingenious builders, as fathers and not just mothers, as queer parents and altruists, as rebel spirits who resist captivity even unto death and, finally, in birds as co-inhabitants of the earth whose lives are parallel to as well as enmeshed with our own. I offer here a bird-centric approach to the commandment, an effort to read it in a spirit of anti-anthropocentrism, drawing on animal studies scholar Matthew Calarco’s notion of indistinction.
Anti-Conceptualism and the Objects of Knowledge and Belief
Authors: Lievers Menno
Published: November 2021

Michael Ayers’s Knowing and Seeing: Groundwork for a New Empiricism is a rich and detailed development of two ideas. The first is that perception presents reality to us directly in a perspicuous way. We thus acquire primary knowledge of the world: “knowledge gained by being evidently, self-consciously, in direct cognitive contact with the object of the knowledge.” (Ayers 2019, 63) The second idea is that concepts are not needed in perception. In this article, the author examines Ayers’s view. The author proceeds as follows: In the first section, he identifies the target of Ayers’s attacks, conceptualism. He then describes why many philosophers have felt this conceptualist view to be attractive. In the next section, he discusses Ayers’s criticisms of conceptualism in an attempt to disentangle these criticisms from the statement of his positive view, which the author discusses in the following section. He ends by describing some problems for Ayers’s positive position that are, so he argues, the result of his vehement opposition to conceptualism.
The Question of Providence and the Problem of Evil in Suhrawardī
Authors: Kaukua Jari
Published: November 2021

Šihāb al-Dīn al-Suhrawardī’s philosophical works seem to contain two conflicting views on providence: in the Talwīḥāt and the Mašāriʿ, he endorses the Avicennian view, only to deny providence altogether in the Ḥikmat al-išrāq. This contribution aims to explain the seeming inconsistency by investigating it in light of the underlying question of God’s knowledge of particular things. I will also argue that despite his qualms concerning providence, Suhrawardī accepts the closely related Avicennian answer to the problem of evil.
‘Christian Patriots’: The Intersection Between Proto-fascism and Clerical Fascism in the Antebellum South
Authors: Roel Reyes Stefan
Published: November 2021

This article examines the convergence between clerical fascism and proto-fascism in the Antebellum South of the United States. The author employs Roger Griffin’s theories of palingenetic ultranationalism and clerical fascism to understand the worldviews of Southern intellectuals. The author argues that a cadre of Southern theologians rejected the liberal heritage of the United States and redefined the relationship between the individual and state. Southern clerical fascists reconceived of an alternative modernity that reflected God’s precepts. Slaves, laborers, and slave masters all had a mandate to guide secular and spiritual progress. Furthermore, these Southern clerics believed the best hope for securing God’s order was to be found in the birth of a new Southern society – the Confederate States of America. This study builds upon the works of other historians who discerned the illiberal and authoritarian qualities of the American South while also contributing to delineation of the protean qualities of clerical fascism.
Facets of Specialization and Its Relation to Career Success: An Analysis of U.S. Sociology, 1980 to 2015
Authors: Heiberger Raphael H. , Munoz-Najar Galvez Sebastian , McFarland Daniel A.
Published: November 2021

We investigate how sociology students garner recognition from niche field audiences through specialization. Our dataset comprises over 80,000 sociology-related dissertations completed at U.S. universities, as well as data on graduates’ pursuant publications. We analyze different facets of how students specialize—topic choice, focus, novelty, and consistency. To measure specialization types within a consistent methodological frame, we utilize structural topic modeling. These measures capture specialization strategies used at an early career stage. We connect them to a crucial long-term outcome in academia: becoming an advisor. Event-history models reveal that specific topic choices and novel combinations exhibit a positive influence, whereas focused theses make no substantial difference. In particular, theses related to the cultural turn, methods, or race are tied to academic careers that lead to mentorship. Thematic consistency of students’ publication track also has a strong positive effect on the chances of becoming an advisor. Yet, there are diminishing returns to consistency for highly productive scholars, adding important nuance to the well-known imperative of publish or perish in academic careers.
Does Protest Against Police Violence Matter? Evidence from U.S. Cities, 1990 through 2019
Authors: Olzak Susan
Published: November 2021

An underlying premise of democratic politics is that protest can be an effective form of civic engagement that shapes policy changes desired by marginalized groups. But it is not certain that this premise holds up under scrutiny. This article presents a three-part argument that protest (1) signals the salience of a movement’s focal issue and expands awareness that an issue is a social problem requiring a solution, (2) empowers residents in disadvantaged communities and raises a sense of community cohesion, which together (3) raise costs and exert pressure on elites to make concessions. The empirical analysis examines the likelihood that a city will establish a civilian review board (CRB). It then compares the effects of protest and CRB presence on counts of officer-involved fatalities by race and ethnicity. Two main hypotheses about the effect of protest are supported: cities with more protest against police brutality are significantly more likely to establish a CRB, and protest against police brutality reduces officer-involved fatalities for African American and Latino (but not for White) individuals. However, the establishment of CRBs does not reduce fatalities, as some have hoped. Nonetheless, mobilizing against police brutality matters, even in the absence of civilian review boards.
Improving Intraoperative Parathyroid Hormone Lab Efficiency
Authors: Pickering John M. , Giles Wesley H.
Published: November 2021

Background

Intraoperative parathyroid hormone (iPTH) testing is often used to confirm successful removal of hypersecreting parathyroid glands during parathyroidectomy. Unfortunately, the iPTH test can be a time-consuming and highly variable process that occurs while the patient is under anesthesia. We set out to improve iPTH lab efficiency and variability.

Methods

We performed a retrospective review of 85 patients who underwent parathyroidectomy at our institution from October 2017 to October 2019. Each step of the iPTH lab reporting process was recorded and analyzed. Three simulations were performed of the entire process. We then established interventions to modify inefficiencies in the process and studied 21 patients who underwent parathyroidectomy at our institution from November 2019 to March 2020.

Results

Twenty-five minutes of time inherent to the process were identified. Four critical steps were identified as modifiable steps in the process: 1. Operating room (OR) blood draw ---> lab receipt. 2. Lab receipt ---> placement on centrifuge. 3. Removal from centrifuge ---> placement on PTH machine. 4. PTH machine result ---> OR verbal report. We improved iPTH lab efficiency by 19%, decreasing the average lab result from 45 to 36 minutes ( P = .001). We improved iPTH lab variability by 62%, decreasing the standard deviation from 21 to 8 minutes ( P = .001).

Discussion

Utilizing a team-based approach to identify and expedite critical steps in the iPTH lab process can make a significant improvement in iPTH lab efficiency, improving patient care by decreasing total anesthesia time.

The top-heavy shape of authoritarian bureaucracy: evidence from Russia and China
Authors: Li Tao , Wang Zhenyu M.
Published: November 2021

The prevalence of top-heavy bureaucracies in non-democracies cannot be explained by the theories of Parkinson, Tullock, Niskanen, or Simon or by classical managerial theories. When bureaucracy positions carry rents, the competition for promotion becomes a rent-seeking process. Borrowing the career-tournament theory framework from managerial scholarship, we argue that top-heavy bureaucracy resembles a tournament with too many finalists. When rent is centralized at the top (i.e. power centralization), as is the case in many non-democracies, the optimal bureaucracy should be top-heavy, accommodating and encouraging relatively more finalists at the top to compete for the final big prize. We provide suggestive evidence by analyzing ministry organizations in China (1993–2014) and Russia (2002–2015). After some fluctuations, the shape of Russian ministries eventually converged with that of China. In the steady state, their ministry shapes are far more top-heavy than what is prescribed by managerial theories. At the micro-level, ministry power centralization, measured by the perceived influence of the ministers, is correlated with ministry top-heaviness in Russia.

Points for practitioners

Our theory suggests that a top-heavy authoritarian bureaucratic structure naturally follows from a back-loaded sequential career tournament and an effort-maximizing bureaucratic leader. Our findings also suggest that Chinese and Russian ministries both converge to a highly top-heavy structure in the long run. We demonstrate that the top-heavy structure first arose during the planned-economy experiment in the Soviet Union. Our research sheds new light on public-sector reforms that aim to reduce bureaucracy top-heaviness in autocracies.

Published: November 2021

Mortuary workers play a crucial role in healthcare delivery by providing after-life care for dead bodies. Mortuary attendants ensure that corpses are well preserved before handing them over to bereaved families for burial. However, the work of mortuary attendants is a neglected area in most low- and middle-income countries, Ghana inclusive.This study explored the nature, duties and job requirements of mortuary attendants in three regions of Ghana. A descriptive exploratory study that utilised a qualitative approach was conducted. Nineteen mortuary attendants who worked in nine mortuary facilities in three regions were purposively selected and interviewed for the study. Semi-structured interviews were audio-recorded using an interview guide. Verbatim transcription of conversations was done, data were manually coded and analysed thematically. Scientific trustworthiness was ensured through applications of the philosophies of credibility, dependability, confirmability and transferability. Three themes were identified: nature of the work of mortuary attendants; qualification and training requirements; and working conditions of mortuary attendants. The emerged sub-themes revealed the critical role played by attendants in preserving the bodies for the families; the majority of attendants got their skills through apprenticeship and challenging work conditions. The lack of structured formal education among mortuary attendants exposes them to occupational hazards and leads to poor service delivery. It is recommended that a formal programme for training, certification and recruitment of mortuary attendants be instituted to equip them with the needed knowledge and skill to enable them to meet the demands of their work.
The Longue Durée of the Marxist Theory of Dependency and the Twenty-First Century
Authors: Martins Carlos Eduardo
Published: November 2021

A critical review of the 50-year-old Marxist theory of dependency and its current situation includes discussion of its analyses of the world-system, the concepts of superexploitation and subimperialism, its reflections on development, democracy, and proposals for emancipation, and its perspectives on the rise of the Latin American left in the twenty-first century and the prospects of neoconservatism. It concludes that with the globalization of capital, Marxist dependency theory must oppose not only internal structures of dependency but the imperialist world order, and this will call for the development of national, continental and global strategies.

Uma revisão crítica dos 50 anos de debates sobre a teoria marxista da dependência e seu estado da arte, que inclui a discussão de suas análises do sistema-mundo, os conceitos de superexploração e subimperialismo, suas reflexões sobre desenvolvimento, democracia e propostas de emancipação, e suas perspectivas sobre a ascensão da esquerda latino-americana no século XXI e as perspectivas do neoconservadorismo. Conclui que, com a globalização do capital, a teoria marxista da dependência deve assumir sua vocação de luta não apenas contra as estruturas internas da dependência mas também contra a ordem mundial imperialista, e isso exigirá o desenvolvimento de estratégias nacionais, continentais e mundiais.
Feature generalization in Dutch–German bilingual and monolingual children’s speech production
Authors: Stoehr Antje , Benders Titia , van Hell Janet G. , Fikkert Paula
Published: November 2021

Dutch and German employ voicing contrasts, but Dutch lacks the ‘voiced’ dorsal plosive /ɡ/. We exploited this accidental phonological gap, measuring the presence of prevoicing and voice onset time durations during speech production to determine (1) whether preliterate bilingual Dutch–German and monolingual Dutch-speaking children aged 3;6–6;0 years generalized voicing to /ɡ/ in Dutch; and (2) whether there was evidence for featural cross-linguistic influence from Dutch to German in bilingual children, testing monolingual German-speaking children as controls. Bilingual and monolingual children’s production of /ɡ/ provided partial evidence for feature generalization: in Dutch, both bilingual and monolingual children either recombined Dutch voicing and place features to produce /ɡ/, suggesting feature generalization, or resorted to producing familiar /k/, suggesting segment-level adaptation within their Dutch phonological system. In German, bilingual children’s production of /ɡ/ was influenced by Dutch although the Dutch phoneme inventory lacks /ɡ/. This suggests that not only segments but also voicing features can exert cross-linguistic influence. Taken together, phonological features appear to play a crucial role in aspects of bilingual and monolingual children’s speech production.
A Knowledge Recombination Perspective of Innovation: Review and New Research Directions
Authors: Xiao Ting , Makhija Mona , Karim Samina
Published: November 2021

A useful theoretical lens for understanding innovation in the strategy and entrepreneurship literatures is knowledge recombination. According to a recombination logic, innovations come about by recombining knowledge components, each of which is associated with a core scientific or technological concept. Interactions among a set of recombined components give rise to new meanings and functions that become the basis of an innovation. The singular focus on the components of knowledge underlying an innovation makes knowledge recombination stand out from other theoretical approaches. The rapid growth in research utilizing a recombination logic suggests that the time is ripe for stepping back and assessing its key insights. Therefore, this review provides a framework for a recombination perspective and considers how the literature using a recombination approach has progressed over time, including identification of key features of knowledge components, influences on how components are recombined, and the outcomes of recombination. Finally, a number of new directions for research are proposed.
The Wheel Comes Full Circle? An Integrated View of Organizational Responses to Institutional Pressures
Authors: Uchida Daisuke
Published: November 2021

In the face of increasing pressure to comply with institutional norms, firm managers may retreat from previous commitments to comply once they realize the challenges involved. This study examines how firms respond to institutional pressures in a particular way called reversion, in which an organization's managers temporarily comply when there are no consequences but resist when it is in their interest to resist. By integrating institutional and agency theories, we model the reversion decision as a tension between institutional constituents and organizational managers. An empirical analysis of a sample of Japanese firms that scheduled annual shareholder meetings during the 2001 through 2014 period was performed. Our findings show that although organizations’ susceptibility to certain institutional pressures determines initial organizational compliance, managers whose interests diverge from those of the institutional constituents can revert their decisions, especially when they have discretion in decision making to protect their own interests. These findings highlight the temporary nature of organizational responses to institutional pressures and help us understand how organizational agency can limit institutional control over an organization's actions.
When the Past and the Present Collide:Contrast Effect of Sequential Psychological Contract Breaches on Employee Outcomes
Authors: Zhong Meng , Wayne Sandy J. , Michel Eric J.
Published: November 2021

Although it is common that employees can experience multiple psychological contract (PC) breaches with their employer over time, it is unclear how a past PC breach serves as a temporal context factor in shaping the impact of a present PC breach on employee outcomes. Integrating contrast effect theory and conservation of resources theory (COR), this research develops and tests hypotheses concerning how a past PC breach alters employees’ reaction intensity to a present PC breach. Three studies were conducted to investigate the hypotheses. In Study 1, findings from 168 employee-supervisor dyads of a building supply company supported the contrast effect of past and present PC breaches. Specifically, when a past PC breach was low, a present PC breach had a stronger negative influence on employee organizational citizenship behavior (OCB). Results of Study 2, comprised of 412 full-time working adults, found that burnout mediated the contrast effect of past and present PC breaches on OCB. Specifically, the negative indirect effects of a present PC breach on OCB through burnout were stronger when a past PC breach was low. In Study 3, 154 subjects participated in a scenario-based experiment in which past and present PC breaches were manipulated. Results supported the contrast effect of past and present PC breaches on anticipated future breach. Implications of these results for future PC breach research and management practice are discussed.

Background

Giant tumefactive perivascular spaces (PVSs) are uncommon benign cystic lesions. They can imitate cystic neoplasms.

Purpose

To evaluate the contribution of advanced neuro magnetic resonance imaging (MRI) techniques in the diagnosis of giant tumefactive PVSs and to further characterize these unusual cerebral lesions.

Material and Methods

The MRI scans of patients with tumefactive PVS diagnosed between 2010 and 2019 were retrospectively reviewed. All imaging studies included three plane conventional cerebral MRI sequences as well as precontrast 3D T1 MPRAGE, post-gadolinium 3D T1 acquisitions, sagittal plane 3D T2 SPACE, diffusion-weighted imaging, and time-of-flight (TOF) angiography. Some patients received perfusion MR, MR spectroscopy, diffusion tensor imaging (DTI), and contrast-enhanced TOF MR angiography.

Results

A perforating vessel was demonstrated in 16 patients (66.7%) by TOF imaging. In four patients, there were intracystic vascular collaterals on contrast-enhanced TOF MR angiography. Septal blooming was observed in four patients in susceptibility-weighted imaging. On perfusion MR, central hyperperfusion was observed in four patients, and peripheral hyperperfusion was observed in one patient. On MR spectroscopy, choline increase was observed in two patients, and there was a lactate peak in three patients, and both a choline increase and lactate peak in one patient. On DTI, there was fiber distortion in five patients and fiber deformation in one patient.

Conclusion

Advanced MRI techniques and 3D volumetric high-resolution MRI sequences can provide a valuable contribution to the diagnosis and can be successfully used in the management of these lesions.

Pancreas divisum (PD) is a common pancreatic malformation caused by the failure of fusion between ventral and dorsal pancreatic ducts. There is a small branch of communication between the two systems in incomplete PD, and this variation has an incidence of 15%. A 43-year-old female patient presented to our department with recurrent abdominal pain. Magnetic resonance cholangiopancreatography (MRCP) showed that the ventral pancreatic duct was curved, with a local pouchlike dilatation. Endoscopic ultrasonography supported the diagnosis of incomplete PD and showed a thin branch of communication between ventral and dorsal pancreatic ducts. Endoscopic retrograde cholangiopancreatography (ERCP) and papillotomy of the minor papilla with double plastic stent implantation were performed. One pancreatic plastic stent was inserted across the minor and major papilla over the guide wire, creating a U-shape. The other wire-guided plastic stent was inserted through the minor papilla into the dorsal pancreatic duct. The pancreatic fluid drained smoothly after stent placement. During the 6-month follow-up, the patient remained well, without recurrence of pancreatitis.
Fuzzy Multiple-Criteria Decision Making Based Evaluation of the Incident Analysis Forms Used in Internal Reporting Systems: A Case Study of Tanker Shipping Companies
Authors: Kececi Tuba
Published: November 2021

Under the International Safety Management (ISM) Code, shipping companies are required to build a Safety Management System and develop procedures that will regulate the incident analysis process. By these procedures, the shipping companies develop an incident analysis form and use it on all ships within their fleets. Although these forms serve a common purpose, their structure shows some differences between companies. Thus, time may be wasted when transferring the data or insufficient data may be obtained. This paper examines incident analysis forms used for tanker ships whose hazardous cargos make them of particular importance. The features of incident analysis forms used on tankers of a shipping company were specified, and the fuzzy analytic hierarchy process (FAHP) method presented their importance levels. Expert opinion was collected by a questionnaire. The results revealed that the highest priorities belong to the sections allocated for details about the ship and environmental conditions and root cause analysis technique. The least essential sub-criteria were related to the structure and variety of the forms. Based on the study results, which captured the current practice and the sector’s expectations, tanker shipping companies’ existing incident analysis forms could be revised. The revised documents would help to achieve complete information and prevent loss of time in information exchange between companies. Bringing a common approach to the analysis of incidents in tanker shipping would increase safety in the shipping industry.
Developing Guidelines for Implementing Transit Signal Priority and Freight Signal Priority Using Simulation Modeling and a Decision Tree Algorithm

Published: November 2021

Transit signal priority (TSP) and freight signal priority (FSP) allow transportation agencies to prioritize signal service allocations considering the priority of vehicles and, potentially, decrease the impact signal control has on them. However, there have been no studies to develop guidelines for implementing signal control considering both TSP and FSP. This paper reports on a study conducted to provide such guidelines that employed a literature review, a simulation study, and a decision tree algorithm based on the simulation results. The guideline developed provides recommendations in accordance with the signal timing slack time, the proportion of major to minor street hourly volume, hourly truck volume per lane for the major street, hourly truck volume per lane for the minor street, the proportion of major to minor street hourly truck volume, the proportion of major to minor street hourly bus volume, the volume-to-capacity ratio for the major street, and the volume-to-capacity ratio for the minor street. The guideline developed was validated by implementing it for a case study facility. The validation result showed that the guideline works correctly for both high and low traffic demand.
Quantifying In Situ Tack Coat Performance Using the TackBond Tester for Quality Control

Published: November 2021

In light of the various quality assurance (QA) issues pertaining to tack coats that occur during construction, there is a need for a means of verifying interlayer bond quality in situ. Despite the immense use of tack coat as a constituent in paving, there are no construction specifications with provisions for the quantification of tack coat bond quality in laboratory or field settings. In this study, a construction QA process for tack coat bond performance was proposed. A novel field tack coat bond strength test device, TackBond, was developed and used for this purpose. The performance of engineered (new tack coat technologies that are tracking less) and conventional tack coats was also evaluated in the laboratory and the field using the developed TackBond test system. The TackBond device was improved in this study by adding features that render it more practical, portable, accurate, and better suited for a variety of pavement surface conditions. Engineered tack coat performance was compared with that of tack coats used conventionally on both milled and overlay surface types. The suitability of the TackBond Test device for capturing the true response of each tack coat was first evaluated by comparing results from TackBond laboratory tests with monotonic direct shear tests (DST) on laboratory-produced samples. Strong correlations between the two test types were achieved. Results of field and laboratory TackBond tests showed that the in situ QA control process developed in this study could be effectively used to improve the in situ tack coat bond performance.
Sources of Mattering for Women and Men: Gender Differences and Similarities in Feelings of Social Significance
Authors: Bonhag Rebecca , Froese Paul
Published: November 2021

Social mattering refers to an individual’s perceived sense of significance in the world and is a key aspect of overall mental health. Using data from a representative survey of adult Americans, we test the extent to which societal-level status, community engagement, group memberships, and interpersonal attachments affect men’s and women’s sense of mattering. We find that women gain social significance to the extent that they feel attached to others interpersonally, in terms of romantic relationships, parenthood, friendships, and closeness to family. Men’s sense of mattering is significantly influenced by broader social factors, like their strength of attachment to the Republican Party, their social media use, and their ability to donate money to the community. These differences suggests that gender norms lead men to also seek significance from the broader community and through group memberships while women rely mainly on their close social ties to feel like they matter.
Comprendre le harcèlement scolaire lié à des motifs de consommation : proposition d’un cadre d’analyse, perspectives de recherche et implications
Authors: Benmoyal Bouzaglo Sarah
Published: November 2021

Le harcèlement scolaire (HS) est un problème de santé publique, avec des risques sociopsychologiques importants. De façon générale, les travaux en marketing ont très peu traité, de façon centrale, du rôle de la consommation dans le développement du HS à l’école chez les enfants et les adolescents. L’objectif principal de cet article est donc de proposer un cadre d’analyse pour l’étude du HS lié à des motifs de consommation relatifs aux produits et aux marques possédés, et à la culture de consommation. Pour ce faire, le HS, ses principales caractéristiques et les différents statuts des pairs impliqués (harceleurs, victimes et témoins) sont définis. Puis, une revue de la littérature sur les jeunes consommateurs permet d’aboutir à la proposition d’un cadre d’analyse structuré autour de variables individuelles et contextuelles pertinentes pour mieux appréhender le HS lié à la consommation. Des perspectives de recherche qui en découlent sont développées, et les implications de ces travaux futurs – pour les chercheurs en marketing, les politiques publiques, les écoles, les parents et les entreprises ciblant les jeunes – sont présentées.
