Job characteristics, well-being and physical activity: A field study using a consumer fitness tracker
Authors: Grossi Nina Raffaela , Gattringer Fabiola , Batinic Bernad
Published: November 2021

The relation between job characteristics and health is one of the most important fields of research within work and organizational psychology. Another prominent variable influencing health is physical activity. The physical activity mediated Demand-Control (pamDC) model (Häusser & Mojzisch, 2017, https://doi.org/10.1080/02678373.2017.1303759) combines these health indicators in a new theoretical framework. Based on the pamDC model the current study aims to clarify the role of leisure time physical activity (LTPA) in the interplay of job demands, job control and well-being. We expect physical activity to partially mediate the impact of job characteristics on health. To avoid self-report bias considering physical activity we used a consumer fitness tracker to collect additional data. In total, 104 white-collar workers participated in the study. The results show that job control and job demands could predict well-being in cross-sectional analyses. In longitudinal analyses, this was only the case for job demands. Regarding the proposed mediating effect of LTPA between job characteristics and health, we could not detect a significant mediation in our sample. This was true for both self-reported and objective data on physical activity. This study provides a first step in validating the pamDC model and has implications for future research.
Revisiting and refining relations between nonsymbolic ratio processing and symbolic math achievement
Authors: Park Yunji , Matthews Percival G.
Published: November 2021

In their 2016 Psych Science article, Matthews, Lewis and Hubbard (2016, https://doi.org/10.1177/0956797615617799) leveled a challenge against the prevailing theory that fractions—as opposed to whole numbers—are incompatible with humans’ primitive nonsymbolic number sense. Their ratio processing system (RPS) account holds that humans possess a primitive system that confers the ability to process nonysmbolic ratio magnitudes. Perhaps the most striking finding from Matthews et al. was that ratio processing ability predicted symbolic fractions knowledge and algebraic competence. The purpose of the current study was to replicate Matthews et al.’s novel results and to extend the study by including a control measure of fluid intelligence and an additional nonsymbolic magnitude format as predictors of multiple symbolic math outcomes. Ninety-nine college students completed three comparison tasks deciding which of two nonsymbolic ratios was numerically larger along with three simple magnitude comparison tasks in corresponding formats that served as controls. The formats included were lines, circles, and dots. We found that RPS acuity predicted fractions knowledge for three university math placement exam subtests when controlling for simple magnitude acuities and inhibitory control. However, this predictive power of the RPS measure appeared to stem primarily from acuity of the line-ratio format, and that predictive power was attenuated with the inclusion of fluid intelligence. These findings may help refine theories positing the RPS as a domain-specific foundation for building fractional knowledge and related higher mathematics.
Testing cognitive and interpersonal asymmetry vs. symmetry among voters in the 2020 Presidential primaries
Authors: Womick Jake , King Laura A.
Published: November 2021

During the 2020 U.S. Presidential primary season, we measured candidate support and cognitive and interpersonal variables associated with political ideology among 831 U.S. participants. Cognitive style variables included openness to experience, active open-minded thinking, dogmatism, and preference for one right answer. Interpersonal variables were compassion and empathy. We modeled candidate support across the political spectrum, ranging from the most conservative to the most liberal (Trump, Bloomberg, Biden, Warren, Sanders), testing competing pre-registered predictions informed by the symmetry and asymmetry perspectives on political ideology. Specifically, we tested whether mean levels on the variables of interest across candidate supporters conformed to patterns consistent with symmetry (i.e., a curvilinear pattern with supporters of relatively extreme candidates being similar to each other relative to supporters of moderate candidates) vs. asymmetry (e.g., linear differences across supporters of liberal vs. conservative candidates). Results broadly supported the asymmetry perspective: Supporters of liberal candidates were generally lower on cognitive rigidity and higher on interpersonal warmth than supporters of conservative candidates. Results and implications are discussed.
Improving Health Equity: The Role of the Oncology Advanced Practitioner in Managing Implicit Bias
Authors: D. Mayden, MSN, FNP, AOCNP, IAC Kelley
Published: November 2021

Implicit bias (IB) is the involuntary activation of thoughts, feelings, attitudes, or stereotypes that exist outside of conscious awareness. Implicit bias develops early in life and research documents the existence of IB across health-care settings. Negative IB impacts patient-provider interactions, produces inferior patient outcomes, and contributes to health-care disparities. Oncology APs are subject to IB and should be aware of its potential impact on professional practice. This manuscript explores the concept of IB and reviews evidence examining the clinical impact of IB in the oncology setting. Strategies for identifying and mitigating IB are explored. Highlights include the use of the Implicit Association Test and emotional intelligence. Advanced practice implications are discussed and range from self-improvement to organizational transformation.

Approche photographique de l’espace documentaire en milieu scolaire : le cas des professeurs documentalistes
Authors: Mazurier Valentine
Published: November 2021

L’article s’intéresse à l’espace documentaire en milieu scolaire tel qu’il est représenté, aménagé, pensé et habité par les professeurs documentalistes. Entre prescription institutionnelle et adaptation contextuelle, l’espace documentaire révèle une vision du lieu qui raconte l’exercice ordinaire du métier de professeur documentaliste et l’interroge en tant que modèle, dans la construction d’une identité professionnelle. Cet article s’appuie sur une recherche menée dans le centre de documentation et d’information (CDI) de cinq collèges français dans le cadre de laquelle professeurs documentalistes et élèves étaient amenés au cours d’un entretien individuel à photographier « leur » espace documentaire. L’espace d’intention photographié par les professeurs documentalistes révèle, derrière l’uniformité des missions, des paysages documentaires hétérogènes qui questionnent les médiations de l’information et le rapport à l’espace documentaire des acteurs de la société de l’information actuelle.
Pobrezas multidimensionales
Authors: Pérez-Foguet Agustí
Published: November 2021

En los últimos veinte años se ha consolidado una metodología que nos permite medir, con un alto grado de consenso internacional, la pobreza multidimensional. Disponer de una metodología de medida ha facilitado concretar y operativizar el concepto. En paralelo, se han propuesto y consolidado propuestas de pobrezas «sectoriales», con entidad conceptual propia. El vínculo entre las dimensiones de la pobreza multidimensional y las pobrezas sectoriales es diverso. En este artículo, se discuten distintos enfoques (pobreza laboral, energética, hídrica, de saneamiento y menstrual). Se argumenta que reducir las pobrezas sectoriales a dimensiones de la pobreza multidimensional limita su utilidad e impacto. Se propone avanzar en la caracterización multidimensional de dichas pobrezas sectoriales, aprovechando para ello el trabajo metodológico realizado previamente en términos de la pobreza multidimensional, en singular, ya consolidado.
Degrowth: a proposal to foster a deeply radical socio-ecological transformation
Authors: Demaria Federico
Published: November 2021

For a sustainable post-Covid-19 recovery strategy, humanity faces two major challenges: 1. Just prosperity: The creation of a resilient and fair economy that delivers prosperity for all; 2. Public and planetary health: protect human health, together with the reduction of environmental impacts below thresholds of planetary boundaries including greenhouse gas emissions. The Covid-19 crisis could represent an opportunity for responses that integrate different goals, or a drawback if some are prioritized without considering their impacts on the others. New kinds of informed solutions are needed to ensure long-term sustainability in social, economic, and environmental terms. This article addresses the research question: How could developed countries manage a sustainable recovery that provides a good life for all within public and planetary health? First, it argues that economic growth is not compatible with environmental sustainability. Green Keynesianism is based on the hypothesis that economic growth can be decoupled from environmental impacts, but this has not happened and it is unlikely to happen. Second, it introduces degrowth as an alternative to green growth. Degrowth challenges the hegemony of economic growth and calls for a democratically led redistributive downscaling of production and consumption in industrialised countries as a means to achieve environmental sustainability, social justice, and well-being. Third, it traces the recent evolution of the term degrowth from an activist slogan to an academic concept. Last, it calls for an alliance of alternatives that could foster a deeply radical socio-ecological transformation.
Conditions and technologies for minimization of protest activity of the Russian youth in the context of modern media discourse in digital environment
Authors: Gavrilov Sergey Dmitrievich , Pankratov Sergey Anatolevich , Azizova Diana Kachabekovna
Published: November 2021

This article is dedicated to the analysis of protest activity of the Russian youth in the context of the institutionalization of the global digital politics. The contradictions existing in the Russian political system are viewed in the form of conflict, which determines the specificity of the reproduction of protest activity of the representatives of youth cohort. The ambiguities in implementation of state policy manifest as the trigger for the formation of protest activity, including mobilization of social activity of youth in constructive / destructive behavioral practices. Research methodology is comprised of the concept of social action in interpretation of M. Weber, T. Parsons, J. Habermas, as well as the theory of social changes developed by P. Sztompka, which allows relying on the thesis of the mutual interaction of structures in relation to the actors in terms of analysis of youth protest. Interpretation is given to the results of discourse analysis of political media texts on the Internet that was conducted by the authors. The scientific novelty consists in determination of the existing expert opinions on the conditions necessary for minimizing protest activity of the youth, as well as most widespread technologies used for their implementation. Of particular importance are the results of the original empirical study that allow interpreting the two positions, which reflect the opinion within the professional environment on the role of youth in protest movement of the Russian Federation, forming the so-called “ideological foundation” for further reasoning on the state and social activity related to protesting youth.

Published: November 2021

The subject of this research is the Shanghai Cooperation Organization and the goals of the Russian Federation therein. This article aims to fill the gap in French historiography and analyze the goals of the Russian Federation in the Shanghai Cooperation Organization through the prism of French researchers. An overview is given to the assessment given by French authors to Russia’s goals in this organization at the stage of its foundation, establishment and development, as well as the overall goals of the Russian foreign policy in post-Soviet space and Central Asia. Special attention is given to the security and energy issues, as well as the growing influence of China and the United States in Central Asia. The relevance of this work is substantiated by the analysis of French research dedicated to the Shanghai Cooperation Organization and the goals of the Russian Federation therein, which is carried out for the first time. For article leans on the monographs and articles by the French historians, political scientists, and experts in the area of international relations dedicated to foreign policy of the Russian Federation in the early 1990s – late 2000s and the Shanghai Cooperation Organization. The conclusion is made that according to the majority of French researchers, the Russian Federation uses the Shanghai Cooperation Organization to strengthen its positions in Central Asia, as well as on the international arena.
Analysis of the visual language of lotus patterns in the Wei, Jin, Southern and Northern dynasties
Authors: Wan Jinbo
Published: November 2021

Lotus is one of the traditional Chinese patterns that runs deep in the history of China. During the rule of Wei and Jin dynasties, as well as Northern and Southern dynasties (222 – 589 AD), Buddhism teaching has become widespread in China. Buddhism affected the traditional Chinese lotus patterns in terms of the used artistic means and methods of expression. Analysis is conducted on manifestation and evolution of the artistic form of the lotus pattern in Chinese culture, as well as the changes in its artistic means of expression and graphics based on the information described in the scientific literature dedicated to artefacts. The conclusion is made that the development and evolution of decorative patterns is often a result of interaction of different cultures and forms of art, rather than continuation of one or another single line. The author summarizes the common artistic form of lotus patterns of this period, as well as the basis of the visual language of lotus patterns and its development. The artistic style of this period under review remains in a relatively stable transitional stage from the perspective of formal expression.
Eighteenth-century visions of the Stone Age
Authors: Kunnas-Pusa Liisa
Published: November 2021

Archaeological concepts of prehistory and the Stone Age are rooted in nineteenth-century scientific discoveries, which extended the human past much further back in time than was previously thought. Without this deep past, the disciplines of archaeology and history would not be what they are today. However, when the division of prehistory into the ages of stone, bronze, and iron was introduced in 1836, it was already an old idea. Stone Age artefacts and the initial phase of human history were discussed in the eighteenth-century academic world, even though the periodisation of history was constructed differently. In the philosophy of the Enlightenment several ideas surfaced which were essential to the formation of archaeology as a scientific practice, and which still affect the way the prehistoric past is imagined. This article examines the concept of a prehistoric, furthest past in Finnish scientific texts, within the framework of eighteenth-century Swedish traditions of science and historiography. How did the scholars in the Academy of Turku view Stone Age artefacts that had a multi-faceted nature in the antiquarian tradition? In what way did their visions of the earliest phase of the Nordic past set up later nationalistic narratives about prehistory?
Böndernas agerande inför och anpassning till storskiftet i sydvästra Finland
Authors: Laine Kirsi
Published: November 2021

This article examines peasants’ goals and means of negotiation in the reallocation of land or enclosure reform called storskifte in the late eighteenth and early nineteenth century in Southwest Finland. It stresses the agency of peasants and their actions in the quest for best practices. The study is based on the meeting minutes of the storskifte reform of 230 villages with mainly freeholders or crown tenants as stakeholders. This article shows how peasants balanced between individualism and collectivism in their decision making because their goals were opposite. They aimed to increase the freedom of work and decision making in the household economy. At the same time, the cooperation with neighbours was an important method of decreasing the workload and costs of farming. Sources indicate that peasants made agreements with each other so they could combine both goals. They achieved independence as farmers as well as low costs by combining consolidation of land with mutual agreements about cooperation in specific issues, but they allowed each other to do individual decisions, too. This kind of flexible solution-seeking behaviour provides a new perspective on the discussion about peasants and agricultural change.

Published: November 2021

The establishment of Agri clinics and Agribusiness Centers is a Government of India Scheme implemented through NABARD and MANAGE, Hyderabad for promotion of rural entrepreneurship through effective training and handholding of the graduate youth.  Agri-Clinics are intended to provide expert advice and services to farmers on various aspects to improve crop/animal yield and increase farmers’ revenue. This study was conducted to assess the quality of services provided by the Agri clinics and agribusiness centers in the union territory of Puducherry. 90 farmers were personally interviewed using the service quality instrument - SERVQUAL to explore their expectation and perception of service quality provided by the Agri -clinics and agribusiness centers. The results indicated that the level of quality of the services provided by the Agri clinics is not to the expected level of the sample farmers i.e., all perception ratings were lower than their expectation scores. In all five dimensions of service quality, a gap was observed between farmers’ perceptions and expectations: Tangible: -0.93, Reliability: -0.89, Responsiveness: -0.78, Assurance: - 0.58, Empathy: -0.61. The results indicated that much more service improvement activities are needed for improving the service quality. The Agri-clinics need to modernize facilities and equipment to reduce the gap between farmers' perceptions and expectations.

Authors: Tu Ai Tran Thi , Phien Huynh Hong , Men Tran Thanh
Published: November 2021

The study aimed to evaluate the toxic ability of the ethanol extract of Ricinus communis (L.) in Drosophila melanogaster fruit fly model. The toxicity was determined through different criteria, including the ability to cause harmful effects on second instar larvae, reproduction, growth and development, and the movement ability of fruit flies. The results showed that the ethanol extract of Ricinus communis expressed its high toxicity against 2nd instar larvae of Drosophila melanogaste with the LD50 value of 64.63 mg/mL. In addition, Ricinus communis extract reduced the growth rate, reproduction and decreased the movement ability of Drosophila melanogaster. The total flavonoid and polyphenol content of the ethanol extract of Ricinus communis were 338.26 mgQE/g extract and 160.43 mgGAE/g extract, respectively. These findings contribute to confirming the toxic properties of ethanol extract of Ricinus communis and their potential use in preventing and controlling pest.

Published: November 2021

In this study, assessment of outdoor background exposure levels in some selected swampy agricultural soil in Nasarawa West, Nigeria has been conducted. An in-situ measurement of outdoor background exposure rate (in mRhr-1) for a total of fifty farms (ten each from Keffi (KF), Kokona (KK), Karu (KR), Toto (TT), and Nasarawa (NS))  were  done  using  a  well  calibrated  portable  halogen-quenched  Geiger  Muller  (GM)  detector (Inspector alert Nuclear radiation monitor SN:3544). A geographical positioning system (GPS) was used at an elevation of 1.0 m above ground level to obtain the geographical location.  The radiological hazard parameters were evaluated using the measured outdoor background exposure rates.  The values obtained were compared with recommended permissible limits to ascertain the radiological hazard status of the swampy agricultural farms.  The  mean  values  of  the  outdoor  background  exposure  levels (0.23, 0.038, 0.028, 0.022, and 0.039 mRh-1), absorbed dose rates (458.49, 334.95, 188.79, 194.01,  and 343.65 nGyh-1) and excess lifetime cancer risk (1.968, 1438, 0.810, 0.832, and 1.475)  each for KF, KK, KR, TT, and NS respectively, are higher than the  recommended  safe  limits  of  0.013  mRh-1,  84.0  nGyh-1,  0.00029 respectively  as  recommended by UNSCEAR and ICRP. On the other hand, the mean annual effective dose equivalent (AEDE) values (0.563, 0.410, 0.232, 0.238, and 0.421 mSvy-1 for KF, KK, KR, TT, and NS respectively) are below the recommended permissible limits of 1.00 mSvy-1 for general public exposure. Generally, the study revealed that swampy agricultural soils in Nasarawa west are radiologically safe with little contamination which could be attributed to the geological formation and partly due to human activity in the area.

Published: November 2021

The content of Mn, Zn, Ni, Cu, Fe, and Pb in 10 samples of Kappaphycus alvarezii (cottonii) and 10 samples of Eucheuma denticulatum (spinosum) from 15 different sites in the intertidal coastal area of Zanzibar were determined by using EDXRF. The heavy metals assessed in both species decreased in the order of Fe >Mn > Zn >Pb> Cu > Ni. In general, the cottonii samples in Unguja had significantly higher (p ≤ 0.05) concentrations of Fe, Zn, Ni, Cu and Pb than the spinosum samples, but the latter had significantly higher levels of Mn. Similarly, the cottonii samples in Pemba had significantly higher (p ≤ 0.05) concentrations of Ni, Cu and Pb than the spinosum samples, but the latter had significantly higher levels of Fe and Zn. The concentrations of heavy metals in cottonii and spinosum in the present study were noticed lower compared to publish results. The results from this study revealed that, the heavy metals contaminations in cottonii and spinosum along the coastal area in Zanzibar were mainly caused by effluents that directly flow into marine environments. Hence, serious measures should be taken to reduce the flow of waste effluents into the marine ecosystem.

Published: November 2021

Carnation is a popular floricultural crop grown widely for its attractive cut flowers. Micro-propagation can be used to create large-scale carnation output. For growth and development, plants require some necessary nutrients as well as growth regulators. Due to the importance of carnation, the present work is carried out using leaf and nodal segments to examine the potential of several plant growth regulators for in vitro callus formation and adventitious shoot regeneration. Explants were sterilized properly with bavistin, sodium hypochlorite and mercuric chloride. The minor contaminated cultures were created by consecutively treating the explants with 0.25% bavistin, 0.50% sodium hypochlorite, and 0.1% mercuric chloride for ten, fifteen, and two minutes.

MS media with 2.5 mg/l 2,4-dichlorophenoxy acetic acid (2,4-D) in combination with 0.75 mg/l naphthalene acetic acid (NAA) resulted in the maximum callus induction (90.47%) from leaf explants. Maximum shoots (76.47%) were produced in MS media supplemented with 2.0 mg/l Thidiazuron (TDZ) + 0.25 mg/l NAA. NAA at 1.25 mg/l was most efficient for maximum root induction (83.32%). In the present study, an effective protocol of carnation explants sterilization was optimized for successful callusing and shoot regeneration.
Power Law Fluid Model for Thermal Elastohydrodynamic Lubrication
Authors: Karimi Samuel Macharia , Gathungu Duncan Kioi
Published: November 2021

The aim of this paper is to analyse thermal elastohydrodynamic lubrication (TEHL) line contact of rolling a bearing using a non-Newtonian uid that is described by the power law model. The performance characteristics of the rolling bearing are determined for various index for dilatant, Newtonian and pseudo plastic uids. The one-dimensional Reynolds and energy equations are both modied to incorporate the non-Newtonian nature of the lubricant. The coupled system of governing equations are discretized using the finite difference method and solved simultaneously. The results show that the pressure, film thickness and temperature for dilatant uids increased with increase in the ow index as compared to pseudo plastic uids. The in uence of thermal effects on pressure and lm thickness is more significant compared with that under isothermal elastohydrodynamic lubrication especially on the case of dilatant uids. The viscosity of the lubricant increases with increase in pressure and reduces with increment in temperature. The surface roughness in the bearing surface increases the lm thickness of the lubricant. The uid pressure, film thickness and temperature increases with increase in the bearing speed. To truly re ect the characteristics of EHL models, thermal effects should be considered.

Published: November 2021

Aims: Diabetes is a chronic non-communicable disease with many irreversible complications that can be prevented by strict adherence to self-care practice. This study aims to investigate the factors influencing adherence to self-care practices among diabetes patients

Study Design: This study adopted a descriptive research design carried out among diabetes patients attending outpatient endocrinology clinic of Obafemi Awolowo University Teaching Hospital, Ile-Ife, Osun State between July and September 2021.

Methodology: Sample size was calculated using Cochran formula and total number of sample used were two hundred and eight (208) diabetes patients. Samples were selected using convenient sampling technique. A self-developed structured Questionnaire on knowledge of diabetes and factors influencing adherence to diabetes self-care practices with reliability index of 0.858 and 0.863 respectively. Two (2) adapted questionnaire; Diabetes self-care practices by Schmitt et al (2013) and Level of adherence to self-care practices scale by Morisky et al. (1986) with reliability index of 0.731 and 0.851 respectively were also used for data collection. Data collected were analyzed using descriptive statistics of frequency, percentage, mean and standard deviation while inferential statistics of Pearson product moment correlation and regression were used to test stated hypotheses at 0.05 level of significance.

Results: The result from the study revealed good knowledge of diabetes mellitus and diabetes self-care practices among the respondents. The results also revealed high level of adherence to diabetes medication, diet, physical activity, blood glucose testing, follow-up and foot care. Factors influencing the level of adherence with diabetes self-care practices include cost of treatment, longer year of being diagnosed, good relationship between healthcare team, level of education, good family and social support. There is also a significant relationship between knowledge of diabetes mellitus and adherence with physical activity (r = 0.210; P = 0.02) and blood glucose testing (r = 0.203; P = 0.003). However, there is no significant relationship between knowledge of self-care practices and adherence to self-care practices; socio-demographic characteristics of age (r = -0.040; P = 0.568), education (r = 0.112; P = 0.107) and adherence to self-care practices.

Conclusion: The study concluded that there was high level of knowledge about diabetes and diabetes self-care practices as well as adherence to diabetes self-care practices, therefore, health care providers should continue to monitor self-care practices among diabetes patients to achieve positive health outcome and reduce morbidity and mortality associated with diabetes mellitus.
Neural Embeddings for Text Analysis: A Case Study in Neoliberal Discourse
Authors: Mandenaki Katerina , Sotirakou Catherine , Mourlas Constantinos , Moschonas Spiros
Published: November 2021

This paper examines the notions of neoliberalism and the financialization and marketisation of public life by using computational tools such as sentence embeddings on a novel corpus of neoliberal articles. More specifically, we experimented with distributional semantics along with several Natural Language Processing (NLP) techniques and machine learning algorithms in order to extract conceptual dictionaries and “seed” words. Our findings show that sentence embeddings reveal repetitive patterns constructed around the given concepts and highlight the mechanical character of an ideology in its function of providing solutions, policies and constructing stereotypes. This work introduces a novel pipeline for computer-assisted research in discourse analysis and ideology.

Authors: Imtiaz Taanya , Priyadharshini R. , Rajeshkumar S. , Sinduja Palati
Published: November 2021

Background: Piper longum, a traditional plant used for regenerative medicine commonly known as the long pepper, is used to treat many pathological conditions. Piper longum is used as a source for obtaining the production of various nanoparticles and testing their efficacy. Piper longum has many beneficial activities, such as antifungal, anti-amoebic, anti-asthmatic, anti-cancer, anti-oxidant, anti-inflammatory, antidepressants activities. Silver nanoparticles are widely and commonly used for its antimicrobial activity against various microorganisms. Our study aimed to synthesize Piper longum based silver nanoparticles and to investigate its anti-oxidant property.

Materials and Methods: Piper longum plant extract was prepared and silver nanoparticles extract was synthesized. DPPH assay was then performed to assess the free radical scavenging activity of the Piper longum silver nanoparticle extract. The further analysis was that the formation of brownish-red color observed was evident, resulting in thesynthesization of silver nanoparticles.

Results: Brown discolouration represents formation of silver nanoparticles and the antioxidant activity was noted to be from 60% to 70% from 10 to 50μL. But when compared to standard vitamin C values the Piper longum silver nanoparticles showed less antioxidant activity.

Conclusion: The Piper longum mediated silver nanoparticles showed remarkable and considerable antioxidant activity but when compared with the standard sample values the antioxidant activity was low.

Introduction

The Boari flap technique is a unique urinary tract reconstruction procedure performed after resection of the urinary tract. However, few previous reports have described the application of this technique to gastrointestinal cancer. Moreover, we have not found any papers describing the long-term prognosis. We report a case of right ureteral tract resection followed by Boari flap reconstruction for rectosigmoid carcinoma, with survival for 108 months without any urologic complications.

Case presentation

A woman in her 50s was diagnosed with rectosigmoid cancer by a local physician and referred to our institution. Computed tomography scans revealed right hydronephrosis caused by rectosigmoid cancer invasion at the lower two-thirds of the right ureter. During laparotomy, massive lymphatic infiltration from the primary lesion to right ureter was observed. After primary tumor resection with lower ureter excision, the Boari flap procedure was performed to reconstruct the ureteral deficit. The postoperative course was uneventful, and she was discharged on postoperative day 20. The patient has been seen every 4 months for 9 years with no recurrence or unpleasant symptoms.

Discussion

This technique is usually performed to manage specific conditions such as ureteral stenosis caused by ureteral calculi, retroperitoneal fibrosis, and gynecologic disorders. This procedure should be reconsidered as a possible option for gastrointestinal malignant cases instead of nephrostomy or cutaneous ureterostomy, given the low rate of complications and high patient satisfaction.

Conclusion

The Boari flap technique is particularly useful for bridging between the ureter and bladder in cases of colorectal malignancy with combined resection of the lower urinary tract.

A prerequisite for commercializing perovskite photovoltaics is to develop a swift and eco‐friendly synthesis route, which guarantees the mass production of halide perovskites in the industry. Herein, a green‐solvent‐assisted mechanochemical strategy is developed for fast synthesizing a stoichiometric δ‐phase formamidinium lead iodide (δ‐FAPbI3) powder, which serves as a high‐purity precursor for perovskite film deposition with low defects. The presynthesized δ‐FAPbI3 precursor possesses high concentration of micrometer‐sized colloids, which are in favor of preferable crystallization by spontaneous nucleation. The resultant perovskite films own preferred crystal orientations of cubic (100) plane, which is beneficial for superior carrier transport compared to that of the films with isotropic crystal orientations using “mixture of PbI2 and FAI” as precursors. As a result, high‐performance perovskite solar cells with a maximum power conversion efficiency of 24.2% are obtained. Moreover, the δ‐FAPbI3 powder shows superior storage stability for more than 10 months in ambient environment (40 ± 10% relative humidity), being conducive to a facile and practical storage for further commercialization.

In recent years, perovskite light‐emitting diodes (PeLEDs) have emerged as a promising new lighting technology with high external quantum efficiency, color purity, and wavelength tunability, as well as, low‐temperature processability. However, the operational stability of PeLEDs is still insufficient for their commercialization. The generation and migration of ionic species in metal halide perovskites has been widely acknowledged as the primary factor causing the performance degradation of PeLEDs. Herein, this topic is systematically discussed by considering the fundamental and engineering aspects of ion‐related issues in PeLEDs, including the material and processing origins of ion generation, the mechanisms driving ion migration, characterization approaches for probing ion distributions, the effects of ion migration on device performance and stability, and strategies for ion management in PeLEDs. Finally, perspectives on remaining challenges and future opportunities are highlighted.

Introduction

Pre‐analytical sample handling might affect the results of Alzheimer's disease blood‐based biomarkers. We empirically tested variations of common blood collection and handling procedures.

Methods

We created sample sets that address the effect of blood collection tube type, and of ethylene diamine tetraacetic acid plasma delayed centrifugation, centrifugation temperature, aliquot volume, delayed storage, and freeze–thawing. We measured amyloid beta (Aβ)42 and 40 peptides with six assays, and Aβ oligomerization‐tendency (OAβ), amyloid precursor protein (APP)699‐711, glial fibrillary acidic protein (GFAP), neurofilament light (NfL), total tau (t‐tau), and phosphorylated tau181.

Results

Collection tube type resulted in different values of all assessed markers. Delayed plasma centrifugation and storage affected Aβ and t‐tau; t‐tau was additionally affected by centrifugation temperature. The other markers were resistant to handling variations.

Discussion

We constructed a standardized operating procedure for plasma handling, to facilitate introduction of blood‐based biomarkers into the research and clinical settings.

Published: November 2021

A new class of axially chiral styrene‐based thiourea tertiary amine catalysts, which have unique characteristics such as an efficient synthetic route, multiple chiral elements, and multiple activating groups, has been rationally designed. These new chiral catalysts have proven to be efficient organocatalysts, enabling the chemo‐, diastereo‐, and enantioselective (2+4) cyclization of 2‐benzothiazolimines with homophthalic anhydrides in good yields (up to 96 %) with excellent stereoselectivities (all >95:5 dr, up to 98 % ee). More importantly, theoretical calculations elucidated the important role of an axially chiral styrene moiety in controlling both the reactivity and enantioselectivity. This work not only represents the first design of styrene‐based chiral thiourea tertiary amine catalysts and the first catalytic asymmetric (2+4) cyclization of 2‐benzothiazolimines, but also gives an in‐depth understanding of axially chiral styrene‐based organocatalysts.

The efficient delivery of reactive and toxic gaseous reagents to organic reactions was studied using metal‐organic frameworks (MOFs). The simultaneous cargo vehicle and catalytic capabilities of several MOFs were probed for the first time using the examples of aromatization, aminocarbonylation, and carbonylative Suzuki–Miyaura coupling reactions. These reactions highlight that MOFs can serve a dual role as a gas cargo vehicle and a catalyst, leading to product formation with yields similar to reactions employing pure gases. Furthermore, the MOFs can be recycled without sacrificing product yield, while simultaneously maintaining crystallinity. The reported findings were supported crystallographically and spectroscopically (e.g., diffuse reflectance infrared Fourier transform spectroscopy), foreshadowing a pathway for the development of multifunctional MOF‐based reagent‐catalyst cargo vessels for reactive gas reagents as an attractive alternative to the use of toxic pure gases or gas generators.

Published: November 2021

AORN conducted its 19th annual compensation survey for perioperative nurses in June and July of 2021. A multiple regression model was used to examine how several variables, including job title, education level, certification, experience, and geographic region, affect perioperative nurse compensation. Comparisons between the 2021 data and data from previous years are presented. The effects of other forms of compensation (eg, on‐call compensation, overtime, bonuses, shift differentials, benefits) on total compensation are also examined. Additional analyses explore the current state of the nursing shortage and the sources of job satisfaction and dissatisfaction.

Published: November 2021

Optically active cyclic dimer, trimer, and tetramer, in which the p‐arylene‐ethynylenes were stacked, were prepared using enantiopure 4,7,12,15‐tetrasubstituted [2.2]paracyclophane as the chiral building block. All molecules exhibited clear Cotton effects in their absorption bands with mirror image spectra, and the signals of the longest wavelengths of the (Rp)‐ and (Sp)‐isomers were positive and negative, respectively. Their circularly polarized luminescence (CPL) signs corresponded with the those of the first Cotton effect. For all molecules, molecular orbitals were localized in one of the stacked p‐arylene‐ethynylenes in the excited states, resulting in a similar photoluminescence behavior. Although the cyclic dimer did not emit CPL, the cyclic trimer and tetramer exhibited intense CPL emissions with a relatively high dissymmetry factor in the order of 10−3. Their optical and chiroptical properties were reproduced by time‐dependent density functional theory calculations.

Ellagic acid as a polyphenol or micronutrient, which can be naturally found in different vegetables and fruits, has gained considerable attention for cancer therapy due to considerable biological activities and different molecular targets. Ellagic acid with low hydrolysis and lipophilic and hydrophobic nature is not able to be absorbed in circulation. So, accumulation inside the intestinal epithelial cells or metabolization to other urolithins leads to the limitation of direct evaluation of EA effects in clinical studies. This review focuses on the studies which supported anticancer activity of pure or fruit‐extracted ellagic acid through in vitro, in vivo, in silico, and drug delivery methods. The results demonstrate ellagic acid modulates the expression of various genes incorporated in the cancer‐related process of apoptosis and proliferation, inflammation related‐gens, and oxidative‐related genes. Moreover, the ellagic acid formulation in carriers composed of lipid, silica, chitosan, iron‐ bovine serum albumin nanoparticles obviously enhanced the stable release and confident delivery with minimum loss. Also, in silico analysis proved that ellagic acid was able to be placed at a position of cocrystal ADP, in the deep cavity of the protein target, and tightly interact with binding pocket residues leading to suppression of substrate availability of protein and its activation inhibition.
