Abstract. Information on marine CO2 system variability has been limited along the Inside Passage of the Pacific Northwest coast of North America despite the region’s rich biodiversity, abundant fisheries, and developing aquaculture industry. Beginning in 2017, the Alaska Marine Highway System M/V Columbia has served as a platform for surface underway data collection while conducting twice weekly ~1600-km transits between Bellingham, Washington and Skagway, Alaska. This dataset allowed for the assessment of marine CO2 system patterns along the Inside Passage, including quantification of the relative importance of key drivers in shaping pCO2 variability. Surface water pH and aragonite saturation state (Ωarag) were determined using the pCO2 data with alkalinity from a regional salinity-based relationship, which was evaluated with discrete seawater samples and underway pH measurements. Low pH and corrosive (Ωarag < 1) Ωarag conditions were seen during winter and in persistent tidal mixing zones, and corrosive Ωarag values were also seen in areas that receive significant glacial melt in summer. The time-of-detection was computed and revealed that tidal mixing zones may be sentinel observing sites with relatively short time spans of observation needed to capture secular trends in seawater pCO2 equivalent to the contemporary atmospheric CO2 increase. Finally, anthropogenic CO2 was estimated and showed notable time and space variability. We theoretically considered the change in hydrogen ion concentration ([H+]), pH, and Ωarag over the industrial era and to an atmospheric pCO2 level consistent with a 1.5 °C warmer climate and revealed greater changes in [H+] and pH in winter as opposed to larger Ωarag change in summer. In addition, the contemporary acidification signal everywhere along the Inside Passage exceeded the global average, with Johnstone Strait and the Salish Sea standing out as potential bellwethers for biological OA impacts. In theory, roughly half the acidification signal experienced thus far over the industrial era may be expected over the coming 15 years with an atmospheric CO2 trajectory that continues to be shaped by fossil-fuel development.
Controls on autotrophic and heterotrophic respiration in an ombrotrophic bog
Authors: Rankin Tracy , Roulet Nigel , Moore Tim
Published: October 2021

Abstract. Northern peatlands are globally significant carbon stores, but the sink strength may vary from year-to-year due to variations in environmental and biogeochemical conditions. This variation is mainly brought about by changes in primary production and ecosystem respiration. The processes that relate to variations in autotrophic respiration (AR; respiration by plant parts) are understood quite well, but heterotrophic respiration (HR; respiration by microbial bacteria in the soil, fungi, etc.) is crudely measured and modelled. This will lead to biased estimates if a change favours one form of respiration over another and alters allocations of carbon to labile pools with different turnover rates. HR has only recently been shown to be more intimately linked to vegetation dynamics than once thought, particularly in wetter, oligotrophic, sedge-dominated ecosystems. The objective of this study is to determine the factors that relate to the spatial and temporal variability in respiration and its autotrophic and heterotrophic components in an ombrotrophic bog (Mer Bleue) where woody shrubs are dominant, and to see if the more dynamic nature of HR in sedges also exists in this bog. Plot level measurements using manual chambers were used to partition respiration from both the dominant shrubs and the sparse sedges at the site, and the controls on respiration were explored by measuring a variety of environmental variables, such as air and soil temperatures (T) and water table (WT) depth. Results show that AR and HR correlate primarily with air and soil T, with WT depth playing an important role in some cases, and that a higher variability in respiration exists for the shrub plots than the sedge plots, especially when WT levels are more variable. Our findings also show that a plant’s response to changes in climate or land-use is related to different mechanisms of obtaining water resources and utilizing symbiotic relationships with other plants around them. These results will improve our understanding of peatland carbon cycling, as well as improve the conceptualization of HR.

Abstract. Climate change will alter the balance between frozen and thawed conditions in Arctic systems. Increased temperatures will make the extensive northern permafrost carbon stock vulnerable to decomposition and translocation. Production, cycling, and transport of dissolved organic carbon (DOC) are crucial processes for high-latitude ecosystem carbon loss that result in considerable export off the Arctic landscape. To identify where and under what conditions permafrost DOC is mobilized in an Arctic headwater catchment, we measured radiocarbon (14C) of DOC and assessed DOC composition with ultraviolet-visible spectroscopy (UV-vis), of surface waters and shallow and deep subsurface pore waters from 17 drainages in the Barrow Environmental Observatory in Alaska. Samples were collected in July and September 2013 to assess changes in age and chemistry of DOC over time. DOC age was highly variable ranging from modern (19 ‰ Δ14C) to approximately 7000 y BP (−583 ‰ Δ14C). DOC age increased with depth, over the summer as the active layer deepened, and with increasing drainage size. DOC quality indicators reflected a DOC source rich in high-molecular weight and aromatic compounds throughout the summer and a weak relationship with DOC age. In deep porewaters, DOC age was also correlated with several biogeochemical indicators, suggesting a coupling between carbon and redox biogeochemistry influencing methane production. In the drained thawed lake basins included in this study, DOC concentrations and contributions of vegetation-derived organic matter declined with increasing basin age. The weak relationship between DOC age and chemistry and consistency in DOC chemical indicators over the summer suggest high lability of old DOC released by thawing permafrost.
Spring onset and seasonality patterns during the Lateglacial in the eastern Baltic region

Published: October 2021

Abstract. Spring onset is an important phenological observation that is sensitive to modern climate change and can be traced back in geological time. The Lateglacial (~14500–11700 cal yr BP) spring onset and growing season (growth-degree-days) dynamics in the eastern Baltic region were reconstructed using the micro-phenological approach based on the dwarf birch (Betula nana) subfossil leaf cuticles. The presented study sites, Lake Lielais Svetinu (eastern Latvia) and Lake Kosilase (central Estonia), are located ~200 km apart in the region affected by the south-eastern sector of the Scandinavian Ice Sheet. During the Lateglacial period the region and its biota were influenced by the retreating glacier and the different stages of the Baltic Ice Lake. The plant macrofossil data confirms that the study sites were located in different vegetation zones (arctic-to-boreal) during the Lateglacial period. The dynamics of the estimated length of the growing season and spring onset, combined with the regional collection of plant macrofossil records, suggest the importance of local settings to species migration. During the Lateglacial warming period (Bølling/Allerød), a notable spring warming and longer growing season was calculated based on micro-phenology, but the treeline did not extend beyond central Estonia. The comparison of pollen- and chironomid-inferred past temperature estimations with spring onset, growth-degree-days, and plant macrofossil data shows coherent patterns during the cooler Older Dryas and warmer Bølling/ Allerød periods while suggesting more complicated climate dynamics and possible warmer episodes during the Younger Dryas cold reversal.

Abstract. We present the Utrecht contribution to the Pliocene Model Intercomparison Project Phase 2 (PlioMIP2), using the Community Earth System Model version 1.0.5 (CCSM4-Utr). Using a standard pre-industrial configuration and the enhanced PlioMIP2 set of boundary conditions, we perform a set of simulations at various levels of atmospheric pCO2. This allows us to make an assessment of the mid-Pliocene reference (Eoi400) climate versus available proxy records and a pre-industrial control (E280), as well as to determine the sensitivity to different external forcing mechanisms. We find that our simulated Pliocene climate is considerably warmer than the pre-industrial reference, even under the same levels of atmospheric pCO2. Compared to the E280 case, the simulated climate of our Eoi400 is on average almost 5 °C warmer at the surface. Our Eoi400 case is among the warmest within the PlioMIP2 ensemble and only comparable to the results of models with a much higher climate sensitivity (i.e. CESM2, EC-Earth3.3, and HadGEM3). This is accompanied by a considerable polar amplification factor, increased precipitation and greatly reduced sea ice cover. A primary contribution to this enhanced Pliocene warmth is likely our warm model initialisation followed by a long spin-up, as opposed to starting from pre-industrial or present-day conditions. Added warmth in the deep ocean is partly the result of using an altered vertical mixing parametrisation in the Pliocene simulations, but this has a negligible effect at the surface. We find a stronger and deeper Atlantic Meridional Overturning Circulation (AMOC) in the Eoi400 case, but the associated meridional heat transport is mostly unaffected. In addition to the mean state, we find significant shifts in the behaviour of the dominant modes of variability at annual to decadal timescales. The Eoi400 ENSO amplitude is greatly reduced (−68 %) versus the E280 one, while the AMOC becomes more variable. There is also a strong coupling between AMOC strength and North Atlantic SST variability in the Eoi400, while North Pacific SST anomalies seem to have a reduced global influence with respect to the E280 through the weakened ENSO

Abstract. Ta (Near-surface air temperature) is an important physical parameter that reflects climate change. Although there are currently many methods to obtain the daily maximum (Tmax), minimum (Tmin), and average (Tavg) temperature (meteorological stations, remote sensing, and reanalysis data), these methods are affected by many factors. In order to obtain daily Ta data (Tmax, Tmin, and Tavg) with high spatial and temporal resolution in China, we fully analyzed the advantages and disadvantages of various existing data (reanalysis, remote sensing, and in situ data). Different Ta reconstruction models are constructed for different weather conditions, and we further improve data accuracy through building correction equations for different regions. Finally, a dataset of daily temperature (Tmax, Tmin, and Tavg) in China from 1979 to 2018 was obtained with a spatial resolution of 0.1°. For Tmax, validation using in situ data shows that the root mean square error (RMSE) ranges from 0.86 °C to 1.78 °C, the mean absolute error (MAE) varies from 0.63 °C to 1.40 °C, and the Pearson coefficient (R2) ranges from 0.96 to 0.99. For Tmin, RMSE ranges from 0.78 °C to 2.09 °C, the MAE varies from 0.58 °C to 1.61 °C, and the R2 ranges from 0.95 to 0.99. For Tavg, RMSE ranges from 0.35 °C to 1.00 °C, the MAE varies from 0.27 °C to 0.68 °C, and the R2 ranges from 0.99 to 1.00. Furthermore, a variety of evaluation indicators were used to analyze the temporal and spatial variation trends of Ta, and the Tavg increase was more than 0.0 °C/a, which is consistent with the general global warming trend. In conclusion, this dataset had a high spatial resolution and reliable accuracy, which makes up for the previous missing temperature value (Tmax, Tmin, and Tavg) at high spatial resolution. This dataset also provides key parameters for the study of climate change, especially high-temperature drought and low-temperature chilling damage, which is publicly available with the following DOI: https://doi.org/10.5281/zenodo.5502275 (Fang et al., 2021a).

Abstract. Records of chemical impurities from ice cores enable us to reconstruct the past deposition of aerosols onto the polar ice sheets and alpine glaciers. Through that, they allow us to gain insight into changes of the source, transport and deposition processes that ultimately determine the deposition flux at the coreing location. However, the low concentrations of the aerosol species in the ice and the resulting high risk of contamination poses a formidable analytical challenge, especially if long, continuous and highly resolved records are needed. Continuous Flow Analysis, CFA, the continuous melting, decontamination and analysis of ice-core samples has mostly overcome this issue and has quickly become the de-facto standard to obtain high-resolution aerosol records from ice cores after its inception at the University of Bern in the mid 90s. Here we present continuous records of calcium (Ca2+), sodium (Na+), ammonium (NH4+), nitrate (NO3−1) and electrolytic conductivity at 1 mm depth resolution from the NGRIP (North Greenland Ice Core Project) and NEEM (North Greenland Eemian Ice Drilling) ice cores produced by the Bern Continuous Flow Analysis group in the years 2000 to 2011. Both of the records have previously been used in a number of studies but have never been published in the full 1 mm resolution. Alongside the 1 mm datasets we provide decadal averages, a detailed description of the methods, relevant references, an assessment of the quality of the data and its usable resolution. Along the way we will also give some historical context on the development of the Bern CFA system.
Impact of Infrared Atmospheric Sounding Interferometer (IASI) thermal infrared measurements on global ozone reanalyses
Authors: Emili Emanuele , El Aabaribaoune Mohammad
Published: October 2021

Abstract. The information content of thermal infrared measurements for tropospheric ozone (O3) estimation has already been well demonstrated. However, the impact of such measurements to constrain modelled O3 distributions within global assimilation systems is not yet unequivocal. A new tropospheric O3 reanalysis is computed for the year 2010 by means of assimilating measurements from the Infrared Atmospheric Sounding Interferometer (IASI) within the MOdéle pour la Chimie Á Grande Echelle (MOCAGE) chemical transport model. The objective is to evaluate the impact of recent methodological improvements of the data assimilation scheme on the O3 distribution. The new O3 reanalysis (named IASI-r) and its precursor (IASI-a) have been validated against ozonesondes, and compared to independent estimations of tropospheric O3 and to results from two state-of-the-art products based on detailed tropospheric chemistry (the Goddard Earth Observing System with a coupled chemistry–climate model, GEOS-CCM, and the Copernicus Atmosphere Monitoring Service, CAMS, reanalysis). The main difference between IASI-r and IASI-a concerns the treatment of IASI observations, with radiances being assimilated directly in IASI-r instead of intermediate Level 2 O3 retrievals. IASI-r is found to correct major issues with IASI-a, such as the neutral or negative impact of IASI assimilation in the extra-tropics and the presence of residual biases in the tropics. IASI-r also compares relatively well to the CAMS reanalysis, which is based on a more comprehensive chemical mechanism and the assimilation of several ultraviolet (UV) and microwave measurements.

Abstract. Introduction: Two-stage revision surgery is the most frequently performed
procedure in patients with a chronic periprosthetic joint infection (PJI).
The infection eradication rates in the current literature differ between 54 % and 100 %, which could be attributed to different treatment strategies.
The aim of this study was to retrospectively evaluate the infection
eradication rate in patients with chronic PJI treated with two-stage
revision surgery of the hip or knee in primary and re-revision cases.
Methods: All patients treated with a two-stage revision for chronic PJI
between 2005 and 2011 were analysed. Patient and infection characteristics were retrieved. Primary outcome was successful infection eradication at last
follow-up. Successful eradication is specified as no need for subsequent
revision surgery or suppressive antibiotic treatment.
Results: Forty-seven patients were treated with a two-stage revision.
Infection eradication was achieved in 36 out of 47 cases. Thirty-eight
patients had positive cultures: 35 monomicrobial infections and 3 polymicrobial infections. Nine cases of culture-negative infections were identified. Accompanying eradication rates were 26 out of 35 cases, 2 out of 3 cases, and 8 out of 9 cases respectively. Mean follow-up was 128 (27–186) months. For hip and
knee revisions the eradication rates were 22 out of 31 cases and 14 out of 16 cases respectively. After primary arthroplasty the infection was eradicated in
29 out of 38 cases and after re-revision in 7 out of 9 cases. Conclusion: In this study, the infection eradication rate for two-stage
revision surgery after PJI of the hip and knee in primary and re-revision
cases was 77 %. No statistically significant patient, infection and micro-organism characteristics were found which influence the infection
eradication rates at long-term follow-up of 128 (27–186) months.

Abstract. The permeability of magma in shallow volcanic conduits controls the fluid flow and pore pressure development that regulates gas emissions and the style of volcanic eruptions. The architecture of the permeable porous structure is subject to changes as magma deforms and outgasses during ascent. Here, we present a high-resolution study of the permeability distribution across two conduit shear zones (marginal and central) developed in the dacitic spine that extruded towards the closing stages of the 1991–1995 eruption at Unzen volcano, Japan. The marginal shear zone is approximately 3.2 m wide and exhibits a 2-m wide, moderate shear zone with porosity and permeability similar to the conduit core, transitioning into a ~1-m wide, highly-sheared region with relatively low porosity and permeability, and an outer 20-cm wide cataclastic fault zone. The low porosity, highly-sheared rock further exhibits an anisotropic permeability network with slightly higher permeability along the shear plane (parallel to the conduit margin) and is locally overprinted by oblique dilational Riedel fractures. The central shear zone is defined by a 3-m long by ~9-cm wide fracture ending bluntly and bordered by a 15–40 cm wide damage zone with an increased permeability of ~3 orders of magnitude; directional permeability and resultant anisotropy could not be measured from this exposure. We interpret the permeability and porosity of the marginal shear zone to reflect the evolution of compactional (i.e., ductile) shear during ascent up to the point of rupture, estimated by Umakoshi et al. (2008), at ~500 m depth. At this point the compactional shear zone would have been locally overprinted by brittle rupture, promoting the development of a shear fault and dilational Riedel fractures during repeating phases of increased magma ascent rate, enhancing anisotropic permeability that channels fluid flow into, and along, the conduit margin. In contrast, we interpret the central shear zone as a shallow, late-stage dilational structure, which partially tore the spine core with slight displacement. We explore constraints from monitored seismicity and stick-slip behaviour to evaluate the rheological controls, which accompanied the upward shift from compactional toward dilational shear as magma approached the surface, and discuss their importance in controlling the permeability development of magma evolving from overall ductile to increasingly brittle behaviour during ascent and eruption.

El objetivo fue analizar las expresiones económicas, políticas y culturales de las mujeres que integran el Tianguis autogestivo, feminista y disidente de la ciudad de Oaxaca, México. La investigación es cualitativa y se sustenta en las técnicas de los estudios etnográficos. El tianguis se forma por la pérdida de empleos que trajo consigo la pandemia del COVID-19 y recupera la forma original de la organización del mercado al concentrar físicamente a productores y compradores, donde el dinero como medio de intercambio se va sustituyendo paulatinamente por el trueque. El sistema hegemónico, capitalista y patriarcal extiende su dominio de manera sutil e imperceptible en la sociedad, se construye de abajo hacia arriba, pero también muestra el carácter intolerante y represivo del poder institucional, sólo así es posible explicar que las autoridades del municipio de Oaxaca desalojaran y recuperaran de manera violenta el espacio público ocupado por las tianguistas. Las mujeres han tenido que colocarse en resistencia y adoptar una posición política ante la falta de acuerdos con las autoridades municipales para poder continuar con el intercambio y venta de sus mercancías.

Los resultados demuestran evidencia de empoderamiento personal y colectivo de las mujeres por participación en la IAP. Las mujeres han co-creado conocimientos y agencia personal y colectiva que han servido para ayudar a cambiar el discurso sobre la IA hacia enfoques más avanzados.
Guaranteed renewability in health insurance: Taking into account changes in risk status and the cost of dying
Authors: Hofmann Annette , Eugster Patrick
Published: October 2021

Guaranteed renewability protects policyholders from reclassification risk. Being an important characteristic of social health insurance, the potential for private insurance markets is high given its property of competing with risk selection. Without regulation, since healthcare expenditures increase strongly near death, it seems questionable whether insurers will be able to sustain guaranteed renewability in the long run - rather than investing in risk selection activity,

In this study, the authors extend the seminal model of Pauly et al. (1995) to include (1) policyholders with improving risk status over time, and (2) policyholders’ high cost of dying. The objective is to find out about the actuarially fair guaranteed renewable premium in realistic conditions when taking into account these two extensions.
EXPLORING THE HR PROFESSIONALS’ EMPLOYEE ADVOCATE ROLE IN A DEVELOPING COUNTRY: The case of Malawi
Authors: Bakuwa Rhoda Cynthia
Published: October 2021

This study specifically explored the key factors that significantly influence the performance of the employee advocate role by HR professionals in a developing country context – Malawi. The study used a standardised questionnaire administered to a random sample of 305 respondents (95 HR professionals, 121 line managers, and 89 employees) drawn from public and private sector organizations in Malawi. The standard multiple regression results revealed that the perception that HR professionals perform the employee advocate role was mainly influenced by the HR professionals’ ability to motivate employees through organizing regular staff meetings. The main implication of the results of this study is that organization of regular staff meetings to listen to the views and concerns of employees is fundamental to the enhancement of the HR professionals’ employee advocate role. Such meetings provide an opportunity for the employees to have their views and concerns heard which is in line with the current wave of democratic dispensation and freedom of expression in many African countries.
The Moderating Effect of Technology Awareness on the Relationship between UTAUT Constructs and Behavioural Intention to Use Technology: A Conceptual Paper
Authors: Abubakar Faruq Muhammad , Ahmad Hartini B.
Published: October 2021

The volume and value of cash-based transactions in Nigeria is high and expected to rise. This is liked to non-adoption of new e-payment process introduced by the Central Bank. The adoption of Point of Sale (POS) terminal is reported to be very low. A number of researchers have used several technology adoption theories to answer a similar phenomenon, but their studies were fragmented. Thus the Unified Theory of acceptance and Use of Technology (UTAUT) combined eight among those numerous theories and models of technology adoption, toward a unified view. However, several studies that used UTAUT and investigate behavioural intention to use technology yielded conflicting findings. Therefore this paper, based on review of past literature, conceptualised that ‘technology awareness’ moderates the relationship between performance expectancy, effort expectancy, social influence, facilitating conditions and behavioural intention to use POS.

The Chinese Exclusion Act and The Late Qing Chinese Cosmopolitanism
Authors: Zhu Ping
Published: October 2021

This article examines a specific set of literary texts, both in English and Chinese, produced by a few Chinatown leaders and some Chinese writers as they protested against the anti-Chinese sentiments and the Chinese Exclusion Act in the second half of the nineteenth century and the first decade of the twentieth century. Those Chinese-authored texts resisted the homogenizing view of the Chinese people by the Westerners, advocating a cosmopolitan class above race, and used commercial amity to assert the Chinese people's cosmopolitan right. The moral compass of the Chinese merchants in those literary stories also puts forward an alternative model of global capitalism that evolved from the traditional Chinese idea of tianxia. Reading these texts can help us build a more historicized view of Chineseness and the Chinese worldview prior to the rise of state-centered nationalisms in modern China, on the one hand, and understand the epistemological framework and limit of modern nationalisms, on the other.

Published: October 2021

Os Parâmetros Curriculares Nacionais (PCNs) do Terceiro e Quarto Ciclos do Ensino Fundamental das Ciências Naturais referenciam ações educativas que significam a adolescência considerando a necessária interação entre a marca orgânica, a puberdade, e os sentidos produzidos cultural e socialmente sobre o corpo e a identidade nesta fase do desenvolvimento humano. À docência em Ciências implica na construção relacional de conhecimentos, valores e atitudes para um adolescer que responda às demandas sobre si, de modo crítico, cognitiva e afetivamente, para manutenção da integridade corporal, da saúde reprodutiva e do comportamento sexual. Esta pesquisa teve por objetivo analisar os alcances das ações e práticas na educação em Ciências na adolescência a partir do conteúdo da fala de estudantes do 9º Ano. Para isso utilizou-se como método de coleta de dados, o Grupo Focal e como instrumento de análise, a Análise do Conteúdo proposta por Bardin. Emergiram três categorias: na primeira, o fator gênero é tomado como referência para indicar as variações de autoimagem e autovalor atribuídos a si mesmos pelos adolescentes; na segunda, autoavaliação da aparência física está relacionada aos padrões culturais de beleza e de ideal do corpo, recaindo sobre os seus valores e julgamentos, potencializando sentimentos de inadequação pela não correspondência às expectativas do modelo predominante; e a terceira, assinala a ausência de uma fonte segura na escola para tomada de decisões. A pesquisa concluiu, neste contexto, que a escola não é um lugar de fala para o adolescente, por tratar de temas ligados a adolescência com impessoalidade, centrando-se no viés biológico da puberdade e negligenciando as questões psicossociais, emocionais e culturais que o adolescer demanda.
O ensino de Física e a prática da ciência: aproximando-os com filosofia de modelos científicos no caso da Física de partículas

Mundialmente, formuladores de políticas públicas, pesquisadores em educação científica, professores e alunos defendem o ensino de tópicos da Física Moderna e Contemporânea na educação básica. Dentre esses tópicos, investiga-se a potencial introdução da Física de Partículas no ensino médio. Neste contexto, há quase duas décadas, surgiram diferentes propostas críticas com relação às abordagens do tipo “Lista de Compras”, que consiste em um ensino que se reduz a apresentar inúmeras partículas elementares. Neste trabalho, propomos um currículo baseado em engajamento, que busca ensinar a ciência e sobre a ciência. A argumentação sobre a ciência é vinculada às pesquisas desenvolvidas na área de Natureza da Ciência. Posteriormente, identificamos os Diagramas de Feynman como modelos a partir da concepção pragmática da Filosofia da Ciência.  Por fim, a partir dessa argumentação, analisamos algumas propostas de ensino que já superaram a “Lista de Compras” vinculadas aos Diagramas de Feynman, e as comparamos a nossa proposta.

Hormonal Physiological Changes of Testis Resulting From Exposure to Vinyl Cyanide and the Possible Protective Role of β-cryptoxanthin in Male Rat
Authors: Al-Zail Nura I.
Published: October 2021

Vinyl cyanide (VCN) is an aliphatic nitrile product which is extensively used in various synthetic chemical industries. VCN is known to exert toxic actions to human beings as well as experimental animals. The present study was designed to examine the ability of β-cryptoxanthin, a naturally occurring antioxidant, to attenuate VCN-induced testicular toxicity in adult albino rats. Daily oral administration of VCN at a dose level of 30 mg/kg b.w. (7.2mg/ animal) to male rats for a period of 5 days significantly reduced the levels of serum testosterone (T), androsterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) which indicates injury to the testis function. Compared to VCN-treated animals, pretreatment with β-cryptoxanthin and its co-administration with VCN once daily at a dose of 40 mg/kg b.w. (9.6mg/ animal) for 30 days induced a remarkable degree of improvement in the levels of endocrine parameters including T, androsterone, FSH and LH. In conclusion, the present results clearly demonstrate the protective role of β-cryptoxanthin against VCN-induced physiological changes in the testis of rats.
The Mediating Role of Adaptive Cognitive Emotion Regulation in the Effect of Deliberate Rumination upon Posttraumatic Growth
Authors: Arıcıoğlu Ahu
Published: October 2021

In this study, the mediator role of adaptive cognitive emotion regulation in the effect of deliberate rumination upon posttraumatic growth was aimed to be analyzed. A convenience sample of 272 university students including 175 (64,3%) females and 97 (35,7%) males was recruited from a university in Denizli, Turkey. Ages of the participants ranged between 20 and 37 with an average age of 21.94 years (SD=1.69). The Posttraumatic Growth Inventory, Event Related Rumination Inventory and Cognitive Emotion Regulation Questionnaire were used for collecting the data. The data were analyzed using SPSS 23 and Amos 22 software packages. Deliberate rumination was determined to be significantly and positively correlated with posttraumatic growth (r=,28, p<,01) and positive cognitive emotion regulation (r=,25, p<,01). Moreover, positive cognitive emotion regulation was significantly and positively correlated with posttraumatic growth (r=,27, p<,01). The results indicated that adaptive cognitive emotion regulation mediated the effect of deliberate rumination on posttraumatic growth. The results, limitations, and implications of the study were discussed.
A Way Forward — Navigating the Integrative Medical Paradigm

The foundational landscape that supports the practice of medicine, and naturopathic medicine by proxy, has shifted and evolved significantly in recent years. What was once dominated by practitioners working in solo offices, has now progressed into a predominantly multidisciplinary setting.1 A shared multidisciplinary space may provide opportunity for both patient and practitioner alike.
Pendekatan Keadilan Gender Pada Penerapan Iddah Ditinjau Dari Studi Islam
Authors: Jannah Riha Nadhifah Minnuril , Faiqoh Naning
Published: October 2021

This paper aims to discuss the concept of iddah which is considered to discriminate against women because it is considered to limit women's movement after divorce or death by their husbands. But in that case Islam actually has clearly regulated in the Qur'an and hadith. Therefore, the problem that wants to be researched and analyzed is how the application of iddah today in Islamis gender equitable and is still relevant if applied. From the research results, there is actually no more injustice of any kind against women, let alone using religious legitimacy to discredit women. Because  basically Islam is earlier than the history of any religion which pays special attention to the dehumanization of humanity experienced by women and serves which function as Khalifah fi al-ard. And iddah is still very relevant if it is applied today because in fact, even though today there are many discoveries and modern sciences that undermine the aims of iddah and assume that there is discrimination against women, infact there are many lessons and goals that can be taken from the process of having iddah.

Constrictive pericarditis is frequently diagnosed during evaluation of the patients for hepatosplenomegaly and easily missed if notconsidered in differential diagnosis. Herein, we present a patient diagnosed with constrictive pericarditis during his investigation forimpaired liver functions and right heart failure one year after liver transplantation.A thirteen-year-old boy presented with abdominal distention, dyspnea and fatigue. He had undergone liver transplantation due toliver failure in the previous year, and the symptoms had recurred in the last three months. Physical examination revealed normalheart sounds. Abdominal distention and ascites were present. Cardiothoracic index and pulmonary vascular markings were normalon chest X-ray. Echocardiography showed biatrial dilatation. Thickening of the pericardium with calcifications was demonstrated bythorax computerised tomography. High pulmonary wedge pressure and equalization of end-diastolic pressures were found duringcatheter-angiography. Pericardiectomy was performed, histopathology was compatible with chronic fibrinous pericarditis. Thepatient improved dramatically after surgery, the right heart failure findings resolved, and the liver graft functions turned to be normal.Constrictive pericarditis must be considered in differential diagnosis of hepatosplenomegaly, liver dysfunction and right heart failuresince surgical treatment is possible and lifesaving.

Ambidextrous management in healthcare networks: governance during the ‘hammer’ and the ‘dance’ in healthcare region west

Crisis management requires health care managers to simultaneously innovate, i.e. to adjust – and to consolidate, i.e. to provide stability. COVID-19 was no exception in this respect. In this study, we ask to what extent multi-actor and multi-level health care networks stimulate or hinder balancing innovation and consolidation. We present the results of a qualitative case study, drawing upon 29 interviews with health care managers in one region in the Netherlands. Our analysis chronologically follows the crisis management response and differentiates between ‘the hammer’ phase (the ‘lockdown’) and the ‘dance’ phase (learning to live with the virus). We show that, especially in the hammer phase, formal networks can contribute to consolidation, yet innovation comes mostly from informal and personal networks. While the hammer phase should help organizations prepare to live and dance with the virus, we show that multi-actor and multi-level networks focus more on idiosyncratic organizational interests, although some of these are in fact productive. We conclude with recommendations for practice.
