Monetary Policy and Redistribution in Open Economies

This paper develops an open-economy heterogeneous-agent New Keynesian model in which households differ in their income, wealth, and real and financial integration with international markets. We use the model to reassess classic questions in international macroeconomics from a distributional perspective. Our analysis yields two main takeaways. First, heterogeneity in households’ international integration plays a central role in driving the unequal consumption responses to external shocks, more so than income and wealth. Second, the conduct of monetary policy in open economies faces a stabilization-inequality trade-off, with fixed exchange rate regimes leading to amplified but more equal consumption responses to external shocks.
The Polar Cap (PC) index combination, PCC: relations to solar wind properties and global magnetic disturbances

The non-negative Polar Cap PCC index built from PCN (North) and PCS (South) indices correlates better with the solar wind merging electric field and is more representative for the total energy input from the solar wind to the magnetosphere and for the development of geomagnetic disturbances represented by the Kp index and ring current indices than either of the hemispheric indices. The present work shows that the ring current index, Dst, to a high degree of accuracy can be derived from a source function built from PCC indices. The integration of the PCC-based source function throughout the interval from 1992 to 2018 without attachment to the real Dst indices based on low latitude magnetic observations has generated equivalent Dst values that correlate very well (R = 0.86) with the real Dst index values, which are represented with a mean deviation less than 1 nT and an overall RMS deviation less than 13 nT. The precise correlation between the real and equivalent Dst values has been used to correct the PCC indices for saturation effects at high intensity disturbance conditions where the Dst index may take values beyond −100 nT. The relations between PCC and the ring current indices, Dst and ASY-H have been used, in addition, to derive the precise timing between polar cap convection processes reflected in the polar cap indices and the formation of the partial and total ring current systems. Building the ring current is considered to represent the energy input from the solar wind, which also powers auroral disturbance processes such as substorms and upper atmosphere heating. With current available PC indices, detailed and accurate SYM-H or Dst index values could be derived up to nearly one hour ahead of actual time by integration of the PCC-based source function from any previous quiet state. Thus, the PCC indices enabling accurate estimates of the energy input from the solar wind are powerful tools for space weather monitoring and for solar-terrestrial research.
Alliance discrepancies in home‐based family treatment: occurrence, development and the therapist’s perspective

In family treatment, building and evaluating multiple alliances with family members is complex. We investigated the occurrence and development of discrepancies between therapists’ alliances with different family members, and therapists’ evaluation of these multiple alliances and discrepancies. Participants were 92 parents and 61 children and adolescents from 61 families receiving home-based family treatment. Family members, therapists, and observers reported early and mid-treatment alliance. We found significant discrepancies, with strongest alliances with mothers, followed by fathers, and then youths. Differences became smaller during treatment. Therapist-reports yielded similar discrepancies as compared to client self-reports and observer-reports. At T1, the correlation between therapist- and client self-reports was moderate and significant for alliances with mothers, but insig-nificant for alliances with fathers and youths. At T2, these correlations were large for alliances with mothers and fathers, but not for youths. Our findings demonstrate that therapists have stronger alliances and are more congruent in their alliance perspective with parents (especially mothers) versus youths.
Thromboembolism in Patients with Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy (HCM) is an inherited cardiac disease, which has a marked heterogeneity in clinical expression, natural history, and prognosis. HCM is associated with a high prevalence of thromboembolic events (stroke and systemic embolic events), even if taking no account of atrial fibrillation (AF), leading to unexpected disability and death in patients of all ages. Several risk factors of thromboembolism such as AF, greater age, left atrial diameter, heart failure and others have been confirmed in patients with HCM. Conventional thromboembolic predictive models were estimated by several trials in HCM population but it turned out to be unsatisfactory. Based on those previous explorations, researchers tried to modify or develop novel models suitable for HCM population in thromboembolism prediction. In consideration of catastrophic advent events of thromboembolism, current guidelines have recommended life-long anticoagulant therapy after a single short AF. Therefore, early identification of risk factors for thromboembolism, accurate risk stratification, timely preventive measures and aggressive management may help to avoid serious adverse thromboembolic events in HCM population.
Enterprise Crowdsourcing and Organizational Culture: Lessons From an Engineering Consultancy

Although enterprise crowdsourcing systems that aim to harness the collective intelligence of employees for innovation purposes are proliferating, little is known about how they may impact organisations and their culture. To shed light on this problem, this paper conducts a case study to investigate an engineering consultancy’s efforts to implement an internal crowdsourcing as part of an effort to change the innovation culture of the organisation. Taking the starting point in the literature on the relationship between IT and organisational culture and enterprise crowdsourcing, this paper underscores the interplay between innovation culture and information technology. Our study finds that enterprise crowdsourcing systems can contribute to small changes of the innovation culture of an organisation along several cultural determinants, including behaviours that encourage innovation, communication and knowledge sharing, employees’ relationships, support mechanisms and strategy.
PARENTING STYLES AND THEIR IMPACTS ON CHILD PROBLEM BEHAVIORS

Managing child problem behaviors as early as possible is crucial. Several studies have shown the impact of parenting on child problem behavior; however, the studies did not investigate the influence of paternal and maternal parenting on child behavior separately. This study aimed to test the effect of mothers’ and fathers’ authoritative and authoritarian parenting on child problem behavior. Furthermore, this study examined the influence of family adjustment on parenting styles. Participants were 105 pairs of parents (fathers and mothers). They completed a set of questionnaires assessing their parenting styles, child problem behavior, and family adjustment. Multiple regression analyses resulted in a significant effect of mothers’ authoritative parenting on child emotional problems, as well as significant effects of fathers’ authoritative and authoritarian parenting on child behavioral problems. Another key finding was that parental teamwork predicted the effectiveness of parenting.
Analysis of curved thin wires radiating over a layered medium and some engineering applications

The paper deals with modelling of radiation from arbitrarily shaped thin wires above a multilayer and related engineering applications. The formulation is based on the set of corresponding Pocklington integro-differential equations (IDEs) for curved wires. The influence of lower layered half-space is taken into account by means of simplified reflection coefficient stemming from modified image theory (MIT). The set of coupled IDEs is handled via Galerkin Bubnov variant of indirect boundary element method (GB-IBEM) for curvilinear elements. The related field radiated from a wire configuration is obtained from corresponding integral expressions including integration of the currents along a given wire configuration. Some illustrative computational examples for certain wire configurations pertaining to dipole antennas, power communication systems (PLC) and instrumental landing systems (ILS) are given in the paper.
Effects of chromium stress on the subcellular distribution and chemical form of Ca, Mg, Fe, and Zn in two rice genotypes

A hydroponic experiment was carried out to study effects of chromium (Cr) stress on the subcellular distribution and chemical form of Ca, Mg, Fe, and Zn in two rice genotypes differing in Cr accumulation. The results showed that Ca, Mg, Fe, and Zn ions were mainly located in cell walls and vacuoles in roots. However, large amounts of metal ions were transferred from the vacuole to the nucleus and to other functional organelles in shoots. Chromium concentrations in the nutrient solution of 50 lM and above significantly decreased Ca concentrations in the chloroplast/trophoplast, the nucleus, and in mitochondria. It further increased Mg concentrations in the nucleus and in mitochondria, as well as Zn and Fe concentrations in the chloroplast/trophoplast. These Cr-induced changes in ion concentrations were associated with a significant reduction in plant biomass. It is suggested that Cr stress interferes with the functions of mineral nutrients in rice plants, thus causing a serious inhibition of plant growth. The chemical forms of the four nutrients were determined by successive extraction. Except for Ca, which was mainly chelated with insoluble phosphate and oxalic acid, Mg, Zn, and Fe were extractable by 80% ethanol, d-H2O, and 1lM NaCl. The results indicated that these low–molecular weight compounds, such as organic acids and amino acids, may play an important role in deposition and translocation of Mg, Zn, and Fe in the xylem system of rice plants.
Sorption of Phthalates on Molecularly Imprinted Polymers

Porous beads of styrene divinylbenzene copolymer, S-co-DVB, imprinted with dimethyl phthalate, DMP, were obtained. Two solvents were applied for the formation of pores: n-hexane and n-octane. The sorbents were prepared by membrane emulsification of monomer mixtures containing DMP followed by suspension polymerization. The average diameters of the synthesized beads were 40 µm for beads obtained from mixtures with n-octane, and 30 µm for preparations with n-hexane as solvent. It was shown that almost all monodispersive sorbents were obtained; their SPAN parameter was as small as 0.7–0.9. Sorption properties of evaluated samples varied in relation to the kind of applied reaction mixture. Generally, imprinted materials showed higher sorption capacity towards DMP than their off-template analogues. For the sorbent obtained in the presence of n-octane and with 3 wt. % of DMP, sorption of dimethyl phthalate took the highest value - 89 mg/g. The sorbents imprinted with DMP were checked for sorption of diethyl phthalate, DEP, and dibuthyl phthalate, DBP also. It was shown that sorbability of synthesized materials towards other phthalates was much smaller than for DMP and was not related to the presence of dimethyl phthalate foot prints.
Temperature-Dependence of Debye-Waller Factors of Semiconductors Presented in Terms of Cumulant Expansion

This work studies temperature-dependence of Debye-Waller factors of semiconductors presented in terms of cumulant expansion in extended X-ray absorption fine structure (EXAFS). The advances in these studies are succeeded based on further development of the anharmonic correlated Einstein model derived primary for fcc crystals into the one for applying to semiconductors and for creating a method having the advantage that all considered quantities are provided based on only the calculation or measurement of second cumulants. Analytical expressions of three first EXAFS cumulants have been derived. They describe the thermodynamic and anharmonic properties and contribute to accurate structural determination of semiconductors. The theory simplifies the many-body task into the one of one-dimensional model with taking the many-body effects into account based on the first shell near neighbor contributions to the vibration between absorber and backscattered atoms. Morse potential is assumed to describe single-pair atomic interaction. The results calculated using the present theory and those obtained by the created method for Ge having diamond structure are found to be in good agreement with experiment and with those of other theorie.
Searching Optimal Target of Perfusion Pressure for Managing Acute Kidney Injury in Critically Ill Patients: An Analysis of Three Large Open Databases

Background: The optimal perfusion pressure target for acute kidney injury (AKI) in critically ill patients remains uncertain. We investigated the association between mean perfusion pressure (MPP) and AKI among critically ill patients and estimated its optimal range.Methods: We analyzed data stored in the Medical Information Mart for Intensive Care (MIMIC) -III, eICU Collaborative Research Database (eICU-CRD), and MIMIC-IV databases. Critically ill patients receiving invasive measurements of MPP for at least 12 hours within the first 24 hours of ICU stay were included. The exposure of interest was the time-weighted average MPP (TWA-MPP) in the first 24 hours. The primary outcome was the incidence of AKI in the next 48 hours. Results: We enrolled 7,992, 8,604, and 6,730 patients from the MIMIC-III, eICU-CRD, and MIMIC-IV databases, respectively. TWA-MPP had higher areas under the curve than mean arterial pressure in predicting AKI in the next 48 hours (0.63 vs 0.57, 0.62 vs 0.58, and 0.64 vs 0.58 in three databases, all p < 0.001). We observed the lowest adjusted risk of AKI when TWA-MPP above 72, 65, and 69 mmHg in the MIMIC-III, eICU-CRD, and MIMIC-IV databases, respectively. Pooled analyses indicated that per 10% increase of proportion of MPP above 65 mmHg was associated with decreased incidence of AKI (adjusted odds ratio = 0.93, 95% confidence interval = 0.92–0.94, p < 0.001). Furthermore, pooled analyses showed that the lowest risk of new-onset, persistence, and progression of AKI was estimated when TWA-MPP above 74, 70 and 65 mmHg, respectively. Conclusions: MPP outperformed mean arterial pressure as a perfusion predictor of AKI. MPP of 65 mmHg or higher may be the optimal target for managing AKI in critically ill patients. The target rises to higher when reversing or preventing AKI.
Anisotropic gels and plasticized networks formed by liquid crystal molecules

Abstract Two component mixtures containing liquid crystalline diacrylates and liquid crystal molecules with no reactive groups have been made. Upon photopolymeriz-ation of the mixtures anisotropic networks containing liquid crystal molecules which were not chemically attached to the networks were created. In these systems the behaviour of the liquid crystal molecules was found to be dominated by the network molecules. Even when the liquid crystal molecules in these networks were heated above their isotropic transition temperature they remained partly oriented, thus contributing to the anisotropy of the system.
Ecology of the neotropical otter (Lontra longicaudis) in southern Tehuacán-Cuicatlán Biosphere Reserve, Mexico

Land otters are predators at the top of the food chain in the rivers where they live and mold the biotic communities at lower trophic levels. The neotropical otter, Lontra longicaudis, is widely distributed in the Americas, but populations are being decimated by hunting, habitat loss, water pollution, and roadkills. An otter population was located in southern Tehuacán-Cuicatlán Biosphere Reserve (TCBR), Mexico. Surveys were conducted in the dry season to determine otter presence, to record physical-chemical data and to collect scats to determine their populational densities and feeding habits. River width and depth, dissolved oxygen and elevation were the significant variables that explained their presence. In the rivers where otters were present, we estimated densities between 0.19 and 0.22 otters/km. We found 12 prey taxa, mainly freshwater fish. In this protected area, the neotropical otter is restricted to large rivers at low elevations, and populations are low. Although otters have diverse feeding habits, they mainly prey upon Poeciliopsis spp. , which constituted 60% of the scats. Density estimates comprise the dry season and were lower than previous surveys, therefore it is necessary to conduct yearly monitoring to identify trends and to implement actions focused on their conservation and management.
Bioacoustics Reveal Species-Rich Avian Communities Exposed to Organophosphate Insecticides in Macadamia Orchards

Organophosphates are the most widely used insecticide class in agriculture. The effects of organophosphates on insectivorous birds can potentially reduce the capacity of these birds to regulate insect pest populations as well as jeopardizing the survival of vulnerable bird species in matrix habitats. In this study, we investigated the diversity of birds inhabiting commercial macadamia orchards in Australia and assessed community-wide exposure of birds to an organophosphate insecticide (trichlorfon). We also studied the impact of trichlorfon on arthropods, and how this affected bird activity. We used a novel approach, combining bird acoustic surveys, and three different arthropod trapping devices. Birds and arthropods were surveyed immediately before and after a trichlorfon application, in sprayed and unsprayed orchards, at six different sites. Surveys showed that trichlorfon applications produced no changes in bird activity, either at the species or community level. Only one species (Lichmera indistincta) showed a significant increase in acoustic activity after treatment. These results indicate that several (62) bird species, some of which have been noted as undergoing regional decline, are exposed to trichlorfon applications. Additionally, trichlorfon applications also produced rapid, negative impacts on certain arthropod groups, particularly spiders. Because almost (80%) of the bird species recorded in the study include arthropods in their diets, then arthropod contaminated by trichlorfon are likely consumed by these orchard-dwelling birds. We recommend that pest management should incorporate strategies to reduce wildlife exposure to toxic chemicals to meet the joint goals of crop production and wildlife conservation in structurally complex agricultural habitats.
Strangle to Resuscitate: Evidence from India

This study examines the performance of two strangle strategies at different legs to ﬁnd the best strategy for consistent proﬁt generation when trading on the Indian stock market index Nifty. These strategies have been analyzed on data ranging from 2007 to 2019 on a monthly basis. Both long and short strangle strategies have been used in this analysis. Using newly developed payoff formulas for both strangle strategies, the performance up to three different legs has been measured based on the monthly success rate, proﬁtability (in terms of points earned or lost), risk and return. The results show that the success rate, proﬁtability, risk and return of the short strangle is better than the long strangle at every leg. Further, the risk and return of the third leg of the short strangle have been compared with other legs of the short strangle, and the results show that the third leg of the short strangle has a lower risk and a higher return than the other two legs of the short strangle option strategy. The regression analysis verified these results. Due to its higher success rate and better proﬁtability, the third leg of the short strangle should be preferred by any trader on the Nifty looking for maximum proﬁt generation. The high success rate, better profitability and better return of the short strangle option strategy indicate that volatility in the Nifty is more bearish than bullish, and the Nifty has directionally range-bound characteristics, which increase as the leg increases. <br><br>
The Friction of Radially Loaded Hybrid Spindle Bearings under High Speeds

Friction losses are an important parameter for evaluating the operational behaviour of high-speed rolling bearings. Specifically, in machine tool applications, the bearings are subjected to high radial loads and high speeds, which lead to increased forces in the rolling contact and, as a result, increased bearing friction. In this high-speed application, hybrid spindle bearings, typically made of ceramic balls and steel raceways, show better frictional behaviour compared to full steel-made bearings. Therefore, precise knowledge of the friction characteristics of high-speed hybrid bearings can improve friction models and generalise them to spindle bearings with different types, geometries, and operating conditions. In this article, a new straightforward and cost-efficient method for measuring the frictional torque in spindle bearings is presented. A rigidly arranged 7008 hybrid spindle bearing pair was tested up to rotational speeds of 24,000 rpm and high radial loads of 3 kN. The effects of oil–air and grease lubrication are discussed in characteristic diagrams of the tested bearings. Then, based on the test results, a friction calculation model is presented and validated for the outer race control and minimised power dissipation regarding the influence of radial forces.
Investigating the relationship between benevolent leadership and the organizational citizenship behaviour of academic staff: The mediating role of leader-member exchange

While research on the relationship between leadership and organizational citizenship behaviours (OCBs) is well-established, empirical knowledge on the influence of benevolent leadership on OCBs through the mediating role of leader-member exchange, particularly in the context of educational management, remains scarce. Moreover, discussion is still limited on benevolent leadership in a Confucian-based culture like Vietnam, as well as the distinction between the two types of academic staff OCBs, namely OCBs directed to the organization (termed as OCBO) and OCBs directed to individuals (termed as OCBI). Based on survey data collected from 333 lecturers in Vietnamese universities, the analysis results confirm the mediating effect of leader-member exchange on the linkages from benevolent leadership to both OCBO and OCBI. University leaders with benevolence can motivate academic staff to engage in extra-role behaviours that benefit not only the organization but also other colleagues and students through nurturing a good quality leader-member exchange.
