The vulnerability to drought-induced embolism-conduit diameter link: breaching the anatomy-physiology divide
Authors: Olson Mark E. , Pace Marcelo R. , Anfodillo Tommaso 
Published: April 2023

Summary
The best explanations of the relationship between organismal form and function-those regarded by scientists as the most solid — always account for both comparative, across-species, patterns, as well as experimental results. This is true in all of biology, as it is for the study of xylem structure-function relations, where there is still a need for xylem physiology and functional comparative wood anatomy to mutually complement each other. To illustrate the magnitude and urgency of this need, we discuss Sherwin Carlquist’s postulate of a link between vulnerability to drought-induced embolism and conduit diameter, summarizing some of the major global patterns of xylem trait variation that are currently explained by postulating a vulnerability–diameter link. These include wider community mean and maximum vessel diameters in wetter vs drier vegetation types; that vessels can be >700 μm in diameter but plants virtually always produce much narrower ones; that dryland plants with wider vessels drop their leaves earlier; wide-to-narrow vessels across growth rings; and the wide vessels of lianas surrounded by narrow vessels. These patterns are global, and we are aware of no anatomical evidence contradicting a vulnerability–diameter link. Despite the pervasiveness of these patterns, many xylem biologists do not regard the patterns as providing guidance for research in functional xylem biology. Instead, proposing and testing hypotheses to account for all of the data — xylem physiology experiments and comparative anatomical patterns in all their complexity and with all of their contradictions — provides the best way forward for the field. This effort requires proposing and testing hypotheses that are consistent with both experimental as well as comparative data. Crucially, it also requires not rejecting the vulnerability–diameter link without providing an alternative explanation that better explains the patterns currently explained by appeal to the link.
The Poetics of the Unconscious in The Idiot and Hegel’s Subject of Philosophical History
Authors: Vladiv-Glover Slobodanka 
Published: April 2023

Abstract
The present paper reads The Idiot in the context of Hegel’s philosophy of history and subjectivity and finds that Dostoevsky’s avowed interest in Hegel led to a substantial absorption of Hegel’s thought in his own aesthetics.
Dostoevsky’s educated readers of the 1860s saw the novel as a moral history of the age, represented through an eccentric « new subject » (or the « new people »), embodied in marionette-like characters. The present paper explores this view further and finds that these marionette-like characters function as agents of the unconscious (and pre-empt the aesthetics of the theatre of the Absurd), which is the source of all subjectivity. Expressivity is the defining feature of subjectivity and is represented by means of pathological states – lying and self-destructive tendencies of the characters who display a pathological demeanour. Caprice (will power) is the prime mover of this subjectivity, which, in the context of Hegel’s philosophy of history, is the driver of the historical process and a direct expression of « Geist » or spirit of the people. This spirit comes to expression in different types of Russian national discourses, embodied in the myriad of embedded stories narrated by the characters on stage and off stage, and in stories within stories of episodic characters. These embedded episodic narratives, consisting of verbal pictures (or ekphrases), tell the story of Russia’s historical development from Peter Great’s time to Dostoevsky’s present of the 1860s. This is the story of the demise of the old « estate culture » of traditional Russia, with a « new Russia » emerging into history, which is grounded in an indeterminate subject of history, whose « pochva » (« soil ») is the groundless ground of language and an ethics of individual freedom. Both of these elements of subjectivity, which define the « new people », are negativities shaping a new dialectics, which is both form and content of the new self-conscious “world-historical individual” – Hegelian Man - through which spirit (Geist) manifests itself in the “present moment” of Dostoevsky’s Russia.
Impact of Exchange Rate on Trade Balance of India: Evidence from Threshold Cointegration with Asymmetric Error Correction Approach
Authors: Mallick Lingaraj , Behera Smruti Ranjan , Bhattacharya Mita 
Published: April 2023

In this research, we investigate the dynamic relationship between the trade balance and exchange rate in the case of India using threshold cointegration and an asymmetric error-correction model. Empirical results validate that the long-run dynamic relationship between the trade balance and exchange rates is asymmetric. In the short run, the trade balance responds only due to positive deviations in the exchange rate. In contrast, in the exchange rate model, the exchange rate reacts only due to negative deviations in the trade balance. In addition, the results exhibit that the adjustment following variation in the exchange rate seems higher than the adjustment in the trade balance in the short run. Besides, the results indicate that the speed of adjustment due to the positive and negative shocks differs in the trade balance and the exchange rate models. Further, the uni- directional Granger causality result suggests that the trade balance substantially affects the exchange rate. However, the Granger causality effect of the exchange rate on the trade balance seems minimal. Finally, our results validate the impact of momentum equilibrium adjustment path asymmetric effects between the trade balance and exchange rate, indicating that the adjustment path is asymmetric in the long run. Therefore, policy planners in India should consider the asymmetric adjustment between these two drivers to overcome trade balance discrepancies in the short and long run.

Published: April 2023

Background Computed tomography (CT) is the reference standard for assessment of the bone. Magnetic resonance imaging (MRI) developments enable a CT-like visualization of the osseous structures. Purpose To assess the diagnostic performance of 3D zero-echo time (3D-ZTE) and 3D T1-weighted gradient-echo (3D-T1GRE) MRI sequences for the evaluation of lumbar facet joints (LFJs) and the detection of lumbosacral transitional vertebrae (LSTV) using CT as the reference standard. Material and Methods In total, 87 adult patients were included in this prospective study. Evaluation of degenerative changes of the facet joints at the L3/L4, L4/L5, and L5/S1 levels on both sides was performed by two readers using a 4-point Likert scale. LSTV were classified according to Castelvi et al. Image quality was quantitatively measured using the signal-to-noise (SNR) and contrast-to-noise (CNR) ratios. Intra-reader, inter-reader, and inter-modality reliability were calculated using Cohen's kappa statistic. Results Intra-reader agreement for 3D-ZTE, 3D-T1GRE, and CT was 0.607, 0.751, and 0.856 and inter-reader agreement was 0.535, 0.563, and 0.599, respectively. The inter-modality agreement between 3D-ZTE and CT was 0.631 and between 3D-T1GRE and CT 0.665. A total of LSTV were identified in both MR sequences with overall comparable accuracy compared to CT. Mean SNR for bone, muscle, and fat was highest for 3D-T1GRE and mean CNR was highest for CT. Conclusion 3D-ZTE and 3D-T1GRE MRI sequences can assess the LFJs and LSTV and may serve as potential alternatives to CT.
The “Control Space” of the State: A Key Element to Address the Nature of Money
Authors: Garzón Espinosa Eduardo , Cruz Hidalgo Esteban , Medialdea García Bibiana , Sánchez Mato Carlos 
Published: April 2023

The academy has traditionally tended to classify the study about money into two approaches that are often considered incompatible: commodity money and debt money. The first one presents money as a commodity that, thanks to its particular characteristics, allows transactions to be carried out in a much more efficient way than the simple barter. The second one considers that money is a type of debt used in a certain institutional context to facilitate transactions, normally issued by one State to distribute the resources produced in the territory over which it exercises its power. In this work, it is argued that these two approaches are not necessarily incompatible and that an analytical tool can be used to detect a common framework and thus better address the nature of money: the “control space” of the State.

A novel adsorbent material for the removal of Copper and chromium metal ions from aqueous solution was prepared by modifying chitosan. Cross linked chitosan material was prepared using vanillin as a crosslinking agent and further it was incorporated with graphitic-C3N4 to obtain the polymeric matrix. The composite material thus obtained was characterized using various characterization techniques such as FTIR, TGA, SEM and XRD. A peak at 1658 cm−1 indicates the formation of Schiff base and the peaks at 2θ = 9°, 15°, 21° and 24° indicates the incorporation of g-C3N4 and the increased crytallinity of the composite material. Adsorption studies were done in order to obtain the maximum capacity of the adsorbent for the Copper and Chromium ions which were found to be 166.66 and 250 mgg−1 respectively. The adsorption isotherm best fitted a Langmuir model and the adsorptive process was found to have pseudo second-order kinetics showing the chemical sorption type. Thermodynamic studies indicated that the adsorption process was spontaneous and endothermic in nature.
Spiritual Leadership and Organizational Commitment: A 21-year Systematic Literature Review
Authors: Lahmar Hakim , Chaouki Farid , Rodhain Florence 
Published: April 2023

In this article, we will attempt to answer the following question: What is the state of 21 years of scientific production regarding spiritual leadership (SL) in its relationship with organizational commitment (OC)? To accomplish this objective, we used a rigorous bibliometric approach employing two scientific databases: Scopus and Web of Science. Eighty-two articles were identified for the period between 2000 and 2021, but only 52 articles have been appropriate for the analysis. Two software were used for the data analysis: IRAMUTEQ and VOSviewer. This systematic literature review was performed to shed more light on our current understanding and to identify patterns and gaps in previous studies of SL as it relates to OC. The results assert that the literature on the relationship between SL and OC has an important role for individuals and organizations. Theoretically, it highlights grey areas that need to be exploited to enrich the scientific literature, including constructs that will moderate or mediate the relationship between SL and OC. Practically, the research perspectives indicate the significant role that the SL can play in paying attention to the spiritual needs of employees and its positive effects on the organization. The findings have implications for both the employees and the organization.

Published: April 2023

Background: Increasing rates of very advanced maternal age (VAMA, 45 years of age and older) are reported worldwide. Data are available on maternal pregnancy-related morbidity, but they are lacking on the infants’ overall post-partum well-being, including congenital malformations, neonatal complications, and breastfeeding status. Methods: We conducted a retrospective review during the period of 7 years (January 2013 to December 2019). Clinical data recorded in the medical files of 626 VAMA mothers and their singleton newborns in comparison to matched controls comprised advanced maternal age (AMA) mothers and mothers between 20 and 35 years of age. Univariate and multivariate analysis of the data was performed. Results: The infants were significantly less exclusively breastfed during hospitalization (17.4% vs 33.9% and 32.1%, respectively, P <.001). The rate of early transient hypoglycemia was also significantly higher among the newborns of VAMA mothers compared to the AMA and younger-aged mothers (14.7% vs 11.8% and 7%, respectively, P <.001), as was special care unit hospitalization (18.7% vs 15.5% and 13.3%, respectively, P =.03). There was no difference in any other analyzed parameters. Conclusions: Newborns of VAMA mothers are less likely to be exclusively breastfed during hospitalization. They do not exhibit significantly increased major neonatal morbidities, but are more likely to sustain hypoglycemia and neonatal caregivers should be alert to the possibility of newborn early transient hypoglycemia. In an era of growing evidence of the beneficial impact of breast milk on development and immunization, VAMA mothers should be guided and encouraged to breastfed their newborns.

Authors: Cao Ying (Jessica) , Wang Yang , Mullahy John , Burns Marguerite , Liu Yao , Smith Maureen 
Published: April 2023

Background: The COVID-19 pandemic changed care delivery. But the mechanisms of changes were less understood. Objectives: Examine the extent to which the volume and pattern of hospital discharge and patient composition contributed to the changes in post-acute care (PAC) utilization and outcomes during the pandemic. Research design: Retrospective cohort study. Medicare claims data on hospital discharges in a large healthcare system from March 2018 to December 2020. Subjects: Medicare fee-for-service beneficiaries, 65 years or older, hospitalized for non-COVID diagnoses. Measures: Hospital discharges to Home Health Agencies (HHA), Skilled Nursing Facilities (SNF), and Inpatient Rehabilitation Facilities (IRF) versus home. Thirty- and ninety-day mortality and readmission rates. Outcomes were compared before and during the pandemic with and without adjustment for patient characteristics and/or interactions with the pandemic onset. Results: During the pandemic, hospital discharges declined by 27%. Patients were more likely to be discharged to HHA (+4.6%, 95% CI [3.2%, 6.0%]) and less likely to be discharged to either SNF (−3.9%, CI [−5.2%, −2.7%]) or to home (−2.8% CI [−4.4%, −1.3%]). Thirty- and ninety-day mortality rates were significantly higher by 2% to 3% points post-pandemic. Readmission were not significantly different. Up to 15% of the changes in discharge patterns and 5% in mortality rates were attributable to patient characteristics. Conclusions: Shift in discharge locations were the main driver of changes in PAC utilization during the pandemic. Changes in patient characteristics explained only a small portion of changes in discharge patterns and were mainly channeled through general impacts rather than differentiated responses to the pandemic.

Background and Objectives: Endovascular aneurism repair (EVAR) is a minimally invasive alternative to open surgery for the treatment of abdominal aortic aneurysm. Iodine contrast medium (ICM) is considered the gold standard, at the high price of related nephrotoxicity and allergic reactions. Carbon dioxide (CO2) has been suggested as an alternative non-nephrotoxic contrast media agent. We aimed to evaluate the safety and the renal impact of the administration of CO2, compared with ICM in EVAR procedures. Design, Setting, Participants, and Measurements: We retrospectively reviewed data of patients who underwent EVAR at the Vascular Surgery Department of the Sant’Orsola Hospital in Bologna. Estimated glomerular filtration rate (eGFR) was evaluated before intervention, immediately after and at 12 months. Results: In total, 22 patients received CO2 and low-dose ICM (CO2 Group) and 22 received standard ICM (Control Group), matched for clinical characteristics and renal function at the time of procedure. Pre and post-operative renal function values (eGFR) were compared between the two groups: in the immediate post-operative the group treated with CO2 and low-dose ICM globally showed a slight improvement in renal function (mean eGFR +5.10%±3.2), meanwhile the group treated with standard dose of ICM presented a significant worsening of renal function compared with pre-procedure values (mean eGFR −9.65%±4). Incidence of post-contrast acute kidney injury (PC-AKI) was 9% in the CO2 group vs 27% in the Control group. At 12 months, the renal impairment was significantly greater in the ICM group than in the CO2 group (mean eGFR decrease −19.2%±11.1 and −7.40%±3.5, respectively). Conclusions: Administration of either CO2 alone or along with low-dose ICM showed to be safer than full-dose ICM alone, lowering the incidence of PC-AKI in patients undergoing EVAR. Unexpectedly, our study revealed also a significant worsening of renal function in patients treated with standard dose of ICM in 1-year follow-up, introducing the concept that acute renal damage caused by ICM could elicit a chronic injury process that affect long-term renal outcomes. Clinical Impact Evaluating the safety and the renal impact of the administration of CO2, compared to Iodinate Contrast Medium, in EVAR procedures represents a first step in order to further tayloring medical procedures on patients characteristics. Our findings can guide the clinicians and surgeons in the procedures choice, not considering only the immediate effect of ICM on renal function but also the potential long-term effects.

Published: April 2023

Background: Sjögren’s syndrome (SjS) is a rare autoimmune disease, and despite our knowledge of SjS, we still lack effective treatments. Chloroquine drugs used to treat autoimmune diseases are still the primary medicine for SjS but increase the risk of chloroquine retinopathy. Objectives: The objective of this study is to use Optical Coherence Tomography Angiography (OCTA) images to monitor the microvascular changes in the fundus of SjS patients after hydroxychloroquine (HCQ) treatment and the feasibility of using them as diagnostic indicators. Design: This is a retrospective observational cohort study. Methods: Twelve healthy controls (HCs group; 24 eyes), 12 SjS patients (SjS group; 24 eyes), and 12 SjS patients treated with HCQ (HCQ group; 24 eyes) were recruited. Three-dimensional OCTA images of the retina were collected, and microvascular density was calculated for each eye. OCTA image segmentation for analysis was conducted using the central wheel division method (C1–C6), hemisphere segmentation method (SR, SL, IL, and IR), and the early treatment of diabetic retinopathy study method (ETDRS) (R, S, L, and I). Results: Retinal microvascular density was significantly lower in the SjS patients compared to the HCs group ( p < 0.05) and much lower in the HCQ group compared to the SjS patients ( p < 0.05). The SjS and HCQ groups differed in the I, R, SR, IL, and IR regions in the superficial and deep retina and the S region in the superficial retina. The ROC curves of the relationship between the HCs and SjS groups and between the SjS and HCQ groups demonstrated good classification accuracy. Conclusion: HCQ may contribute significantly to the microvascular alteration in SjS. Microvascular alteration is a potential marker with adjunctive diagnostic value. The MIR and the OCTA images of I, IR, and C1 regions showed high accuracy in minoring the alteration.
Somali Refugees, Informality, and Self-initiative at Local Integration in Ethiopia and Kenya
Authors: Muhumad Abdirahman A. , Jaji Rose 
Published: April 2023

As the number of refugees has continued to grow in post-independence Africa, host governments across the continent have developed stringent refugee policies that are detached from historical transborder relationships in which refugees and host communities interact. The stringent policies are underpinned by the assumption that host communities view refugees from the state-centric perspective of non-citizens as undesirable foreigners or outsiders. Host governments’ insistence that the solution lies in refugees eventually repatriating to their countries of origin drives refugee policies that undermine solutions instead of building and capitalizing on solutions generated at the level of host communities. The exclusion of local histories and social dynamics in host regions has led to policies that neither hold up to humanitarian standards nor serve their intended non-integration objectives. Some host governments are reluctant to implement local integration and have maintained exclusionary policies for a long period of time when the realities in the host communities show that refugees are included and participate in various community activities. Host governments perpetuate this disjuncture between policy and local practice by assuming or pretending that refugees will wait for repatriation instead of finding solutions in the host countries where some of them have lived for decades. Contrary to the non-integration objectives of official encampment policies and scholarship that assumes that the absence of official integration policies deters integration, many refugees have defied the stereotypical portrayal of refugees as “bare life” which denotes prioritization of mere survival as opposed to the quality of life. They have managed to find solutions and live their lives as active and productive members of their host countries. This article specifically addresses the situation of Somali refugees in Ethiopia and Kenya. It argues that the absence of local integration policies or reluctance by host governments to implement them where they exist does not automatically mean that refugees are unable to integrate in their host countries. Host government policies against integration are mediated by refugees’ self-initiative and resourcefulness. These characteristics are facilitated by host communities whose ties and mutual dependence with refugees, cultivated pre- and post-flight, play an important role in engendering solidarity and circumventing policies that hamper refugees’ quest for long-term solutions. Based on the research findings, the paper recommends that host governments pursue policies that are informed by the shared needs and interests between refugee and host communities and that build on the social dynamics and relationships in refugee-hosting regions.
