Post-COVID Inflation Dynamics: Higher for Longer

In the December 2022 Summary of Economic Projections (SEP), the median projection for four-quarter core PCE inflation in the fourth quarter of 2025 is 2.1 percent. This same SEP has unemployment rising by nine-tenths, to 4.6 percent, by the end of 2023. We assess the plausibility of this projection using a specific nonlinear model that embeds an empirically successful nonlinear Phillips curve specification into a structural model, identifying it via an underutilized data-dependent method. We model core PCE inflation using three components that align with those noted by Chair Powell in his December 14, 2022, press conference: housing, core goods, and core-services-less-housing. Our model projects that conditional on the SEP unemployment rate path and a rapid deceleration of core goods prices, core PCE inflation moderates to only 2.75 percent by the end of 2025: inflation will be higher for longer. A deep recession would be necessary to achieve the SEP’s projected inflation path. A simple reduced-form welfare analysis, which abstracts from any danger of inflation expectations becoming unanchored, suggests that such a recession would not be optimal.
Self-fields in a planar wiggler and axial magnetic field

A theory for self-fields induced by charge and current densities of the electron beam in a free-electron laser with planar wiggler and axial magnetic field is presented. Mutual influence of the electron velocity and self-magnetic field is considered to account for the total self-magnetic field. The quasisteady-state orbits and their stability under the influence of self-fields are derived and discussed. The function Φ which determines the rate of change of axial velocity with energy is then derived. It is shown that for a planar wiggler, the wiggler-induced self-magnetic has two components. The first one is perpendicular to the wiggler magnetic field and the second is parallel (or antiparallel) to the wiggler magnetic field. The wiggler-induced self-magnetic field has a diamagnetic effect for group I orbits, while for group II orbits it has a paramagnetic effect. Some interesting effects of self-fields on electron dynamics include the generation of a negative singularity for function Φ and creation of new.
Effects of Different-Sized Cages on the Production Performance, Serum Parameters, and Caecal Microbiota Composition of Laying Hens

Simple Summary Cage size is an essential environmental factor affecting the well-being and performance of hens and thus it is necessary to determine the extent of its contribution. The present study investigated the effects of four different-sized cages, i.e., huge, large, medium, and small cages, on the productive performance, serum biochemical indices, and caecal microbiota composition of Roman laying hens. The results indicated that enlarging cage size has some positive effects on the productive performance, lipid metabolism, and antioxidant capacity of laying hens, while medium cages were superior to large cages in feed conversion efficiency and caecal microflora composition. Abstract The effects of four different-sized cages—huge (HC), large (LC), medium (MC), and small (SC) cages—on the productive performance, serum biochemical indices, and caecal microbiota composition of Roman laying hens were investigated. At 44 weeks of age, a total of 450 hens were selected and allocated to the four groups, with six replicates each. Equal stocking density (0.054 m2 per bird) was maintained among the four groups throughout the experiment, and number of birds/cage changed for each treatment. After 2 weeks of preliminary trial, the formal experiment was performed from 46 to 60 weeks of age. The laying rate and feed conversion ratio (FCR) were determined daily, antibody titres were measured every 3 weeks, and serum biochemical parameters and caecal microbiota composition were analysed at 60 weeks of age. Compared to HC and SC, the higher laying rate and lower FCR in MC and LC indicated positive effects on egg production and feed efficiency, while SC showed the highest body weight gain (p < 0.05). With increasing cage size, the serum triglycerides (TG) and total cholesterol (T-CH) levels were reduced, and serum glutathione peroxidase (GSH-Px) activity improved, where birds raised in HCs had the lowest serum TG and T-CH and the highest GSH-Px activity. Twenty-nine different phyla and 301 different genera were detected in the caecal microbiota of birds in the four groups. Methanobrevibacter was significantly higher in the SC than in the other groups (p < 0.05). Faecalibacterium was most abundant in the MC compared with the other groups (p < 0.05) and was significantly positively correlated with serum GSH-Px concentration (R = 0.214, p = 0.0017). Lactobacillus was significantly less abundant in the LC and MC than in the HC and SC groups (p < 0.05) and was significantly positively correlated with body weight (R = 0.350, p = 0.0009) but negatively correlated with laying rate and FCR. In conclusion, MC were superior to HC and LC in improving feed conversion efficiency and caecal microflora composition compared to the SC. An appropriate increase in cage size is beneficial to laying hen production and health.
Survival and Adaptation of a Released Group of Confiscated Capuchin Monkeys

One commonly used method of managing confiscated wild primates in Latin American countries is to release rehabilitated individuals back to their natural habitats. However, little information has been collected from confiscated animal releases, so no clear guidelines have been developed to measure the success of this type of procedure. In most countries, the collection of critical post-release data is too costly and time-consuming for it to be incorporated into the routine procedures of institutions managing confiscated fauna. Therefore, this project was carried out in conditions similar to those of other Colombian and Latin American rehabilitation centres. A group of eight confiscated and rehabilitated brown capuchin monkeys (Cebus apella) was released in Los Llanos Orientales in Colombia, and monitored for 6.5 months to determine their adaptation and survival after release. Results were analysed according to how the animals adapted to their new environment in terms of foraging, feeding, locomotion, sleeping, social interactions between the group and with other animals and species, prédation, orientation, and establishment of a territory. The results show that the short-term adaptation and survival of the group 6.5 months after release was successful. Five of the eight animals remained together, two separated, and only one was lost during the first month. Implications for animal well-being are discussed.
A Thematic Analysis of Fake News in India During the Pandemic

ABSTRACT This study identifies the different fake news verified by PIB fact-checking site. This study verified different themes along with the frequency of fake news which was verified by PIB site of Indian Government. As the data were collected during pandemic, this study attempted to find out the frequency in which different aspects of covid-19 were manipulated as fake news and subsequently shared through different media platforms. The fake news producers used different media platforms, including mainstream and social media, to disseminate fake news. This study also identified the different media applications where fake news were spread in large numbers by giants of fake news. The study also found that misinformation can be disseminated in different forms and languages too.
Organizational climate, job satisfaction, and burnout in nursing workers

Introduction Characterized by high levels of emotional exhaustion and depersonalization and reduced professional accomplishment, burnout syndrome has been a major cause of psychic illness in nursing workers, with a serious impact on the quality of services and on patient safety Objectives To analyze the correlation between organizational climate, job satisfaction, and burnout in nursing workers. Methods This is a cross-sectional study with a sample of 534 Brazilian nursing workers. We used the Organizational Climate Scale for Health Organizations, the Job Satisfaction Questionnaire (S20/23), and the Maslach Burnout Inventory. An analytical descriptive analysis of the data was performed using relative and absolute frequencies, mean, standard deviation, minimum, maximum, and correlation test between the variables. Results Organizational climate and job satisfaction were evaluated as regular. With regard to burnout, moderate levels of emotional exhaustion, low levels of depersonalization, and high levels of professional accomplishment were observed. A strong positive correlation was found between job satisfaction and organizational climate; in addition to a moderate negative correlation between emotional exhaustion and both organizational climate and job satisfaction, and a moderate negative correlation between depersonalization and job satisfaction. Conclusions Organizational climate and job satisfaction had a negative correlation with burnout dimensions, representing possible protective factors.
Effect of Vacancy Defect Content on the Interdiffusion of Cubic and Hexagonal SiC/Al Interfaces: A Molecular Dynamics Study

The mechanical properties of ceramic–metal nanocomposites are greatly affected by the equivalent properties of the interface of materials. In this study, the effect of vacancy in SiC on the interdiffusion of SiC/Al interfaces is investigated using the molecular dynamics method. The SiC reinforcements exist in the whisker and particulate forms. To this end, cubic and hexagonal SiC lattice polytypes with the Si- and C-terminated interfaces with Al are considered as two samples of metal matrix nanocomposites. The average main and cross-interdiffusion coefficients are determined using a single diffusion couple for each system. The interdiffusion coefficients of the defective SiC/Al are compared with the defect-free SiC/Al system. The effects of temperature, annealing time, and vacancy on the self- and interdiffusion coefficients are investigated. It is found that the interdiffusion of Al in SiC increases with the increase in temperature, annealing time, and vacancy.
The Spectra of Young Protostars of Cepheus A

Radio data obtained over more than 13 years of monitoring give detailed spectra of the youngest known protostars in the young star formation region Cepheus A. Two sources, namely HW 2 and HW 3(d), increase in flux density from 15 to 43 GHz, as previously known. The data confirm that HW 2 appears to be thermal, producing two ionized jets, and these jets show an averaged separation speed of 95 km s-1, in comparison with the difference in the red and blue HCO+ outflow velocities of 54 km s-1. The jets appear to be acting as pistons to produce the molecular outflows. HW 3(c) has time-dependent spectra which decrease between 1.4 and 4.9 GHz, rise to a peak near to 15 GHz, and then fall rapidly to 43.3 GHz. The low-frequency emission appears to be synchrotron radiation from a jet, and the high-frequency emission indicates gyrosynchrotron radiation. HW 3(d) is somewhat similar at the lower frequencies but at the higher frequencies is doubly peaked. One component has a steeply rising spectrum, as for HW 2. HW 3(d) is similar to the double source of L1551 NW but is unlikely to be a double protostar. The data from the whole region, including previous analyses, show time-dependent events that are less than 1000 yr old. The events consist of variations in both flux density and spectra and involve high-energy electrons. These time-dependent variations, together with measured proper motions, indicate that extremely energetic events occur in protostars before they reach the Class 0 stage and could play an important part in dispersing the surrounding gas. Caution must be observed when interpreting processes in protostar-forming regions if they are observed only in the snapshot mode.
Transmission into staggered parallel-plate waveguides

The modal field transmitted into a staggered parallel-plate waveguide when illuminated by a line source is studied. To widen the limited applicability of existing ray methods, an aperture field integration (AFI) method is developed, in which the field in the waveguide aperture is first calculated by high-frequency techniques (uniform asymptotic theory (UAT) and spectral theory of diffraction (STD)) and then decomposed into modal fields via the Fourier analysis. For problems in which the exact Wiener-Hopf and/or the ray solutions are available, AFI gives excellent numerical results. New results are staggered waveguides which find application in the analysis of a waveguide lens.
Effect of the misalignment between the applied and internal magnetic fields on the critical currents of “tilted coated conductors”

We present angular-dependent measurements of the critical current density (Jc) of a YBa2Cu3O7 film grown on tilted buffered Ion-Beam-Assisted-Deposition MgO metal tapes. We compare samples with the current parallel and perpendicular to the tape’s direction. In samples with the current parallel to the tape, we observe an asymmetric angular dependence of Jc and a shift of the ab-planes maxima position with the magnetic field strength. The shift is a result of the misalignment between the applied and internal magnetic fields. The misalignment effect takes place at fields lower than 3T at T=75.5K. For samples with the current perpendicular to the tape, we find an overall reduced value of Jc, the angular behavior is symmetrical, and no shift in the maxima position as a function of the magnetic field is observed. These results indicate that the effect of misalignment between the applied and internal magnetic fields must be taken into account when studying the angular dependence of Jc.
Evolution of the 155 Day Periodicity in Sunspot Areas during Solar Cycles 12 to 21

Sunspot area data during solar cycles 12-21 are examined with both periodogram and evolutionary spectral analysis techniques for evidence of a periodicity near 155 days. This periodicity is found to be present only during epochs of maxium activity, when it modulates the sunspot areas by as much as 15-20 percent of the amplitude of the 11 yr cycle. The 155 day periodicity typically occurs in episodes of from 1 to 3 yr, with sequential episodes often in opposite solar hemispheres; the strengths of these episodes appear to track the general level of solar activity. Comparing the phases of sinusoids fitted to the sunspot area data within individual solar cycles provides evidence for coherency within + or - 8 days of a period at 155 days between solar cycles 19, 20, and 21. However, within any one episode the actual period of the 155 day cycle may drift from 130 to 185 days. 31 refs.
Impact of business regulations on foreign direct investment inflows and economic growth in East African countries

Abstract Continuous improvement of the business environment is important for countries seeking to benefit from increased trade and investment through regional integration. Creating an enabling environment for businesses to thrive and expand has become a new concept in international development organizations, and a good business climate allows good ideas to take root, which leads to the creation of jobs and better lives for host countries. The main objective of this study was to investigate the impact of business regulations on FDI inflow and economic growth in East Africa region using data collected from the World Bank spanning from 2010–2019. The study finds that dealing with construction, enforcing contracts, getting credit, getting electricity, paying tax and protecting minority investors have a significant impact on FDI inflow in the region. While enforcing contracts, getting credit, protecting minority investors, resolving insolvency, starting a business and trade across borders have a significant impact on economic growth in the region. Moreover, each additional reform during 2010–2019 is associated, on average, with a 3.09% increase in FDI inflows and 2.24% increase in GDP in East African countries. The findings of this study will help policy makers in the region to establish a strong legal framework of business regulations to attract FDI inflow into their economies, to adjust their ease of doing business procedures to attract FDI to their economies and to promote regional economic growth. This will also assist investors in monitoring these key indicators to facilitate investment decisions in foreign countries.
Group LASSO for Structural Break Time Series

Consider a structural break autoregressive (SBAR) process where j = 1, …, m + 1, {t1, …, tm} are change-points, 1 = t0 < t1 < ⋅⋅⋅ < tm + 1 = n + 1, σ( · ) is a measurable function on , and {ϵt} are white noise with unit variance. In practice, the number of change-points m is usually assumed to be known and small, because a large m would involve a huge amount of computational burden for parameters estimation. By reformulating the problem in a variable selection context, the group least absolute shrinkage and selection operator (LASSO) is proposed to estimate an SBAR model when m is unknown. It is shown that both m and the locations of the change-points {t1, …, tm} can be consistently estimated from the data, and the computation can be efficiently performed. An improved practical version that incorporates group LASSO and the stepwise regression variable selection technique are discussed. Simulation studies are conducted to assess the finite sample performance. Supplementary materials for this article are available online.
Binaural Vector Model: Relative Interaural Time Differences

Further computations on the binaural vector model have been carried out [H. Levitt and E. A. Lundry, J. Acoust. Soc. Am. 39, 1232(A) (1966), and references cited therein]. The cumulative probability distribution of the phase angle between the left‐ and right‐ear resultant vectors has been computed for the case where either the noise or the signal has been subjected to an interaural time difference. It is assumed that interaural time difference is the relevant variable for binaural signal detection under these conditions. Based on this assumption, the resolution required of the binaural system for consistency with available binaural masking‐level difference (BMLD) data has been computed. An interpretation of the results in terms of short‐term crosscorrelation is presented.
Models of Compact Simple Kantor Triple Systems Defined on a Class of Structurable Algebras of Skew-Dimension One

Let (A,−): = ℳ(J) be the 2 × 2-matrix algebra determined by Jordan algebra J: = H 3(𝔸) of hermitian 3 × 3-matrices over a real composition algebra 𝔸, where (−) is the standard involution on A. We show that the triple systems B A (x, ∼,z), x,y,z ∈ A, are models of simple compact Kantor triple systems satisfying the condition (A), where B A (x,y,z) is the triple system obtained from the algebra (A,−) and (∼) denotes a certain involution on A. In addition, we obtain an explicit formula for the canonical trace form for the triple systems B A (x, ∼,z).
PERIOD CHANGES OF RR LYRAE STARS IN GLOBULAR CLUSTERS

We have used data from the literature to reexamine the period changes of RR Lyrae variables in seven globular clusters. There is a tendency for the ore extreme rates of period change to be found in RRab rather than RRcd stars. Particularly absent from the RRcd star sample are stars showing large rates of period decrease, a result which may in part reflect the small proportion of RRcd variables in Oosterhoff type I clusters. The apparent coupling of period change to pulsation mode is not easily interpreted as an evolutionary effect, and appears to be without adequate explanation.
Comparing Post-Exercise Hypotension after Different Sprint Interval Training Protocols in a Matched Sample of Younger and Older Adults

This study assessed the post-exercise hypotension (PEH) effect in a sample of matched young and older adults after different sprint interval training (SIT) protocols. From forty-three participants enrolled in this study, twelve younger (24 ± 3 years) and 12 older (50 ± 7 years) participants, matched for the body mass index, systolic blood pressure, and VO2max-percentiles, were selected. The participants completed two SIT protocols consisting of 4 × 30 s exercise bouts interspersed by either one (SIT1) or three minutes (SIT3) of active rest. The peripheral systolic (pSBP) and diastolic (pDBP) blood pressure, central systolic (cSBP) and diastolic (cDBP) blood pressure, pulse wave velocity (PWV), and heart rate (HR) were obtained before and at different measurement time points (t5, t15, t30, t45) after the exercise. No significant time × group interactions were detected in pSBP (p = 0.242, η² = 0.060), pDBP (p = 0.379, η² = 0.046), cSBP (p = 0.091, η² = 0.861), cDBP (p = 0.625, η² = 0.033), PWV (p = 0.133, η² = 0.076), and HR (p = 0.190, η² = 0.123) after SIT1. For SIT3 no significant time × group interactions could be detected for pSBP (p = 0.773, η² = 0.020), pDBP (p = 0.972, η² = 0.006), cSBP (p = 0.239, η² = 0.060), cDBP (p = 0.535, η² = 0.036), PWV (p = 0.402, η² = 0.044), and HR (p = 0.933, η² = 0.009). Matched samples of young and older adults reveal similar PEH effects after HIIT. Accordingly, age does not seem to affect PEH after SIT. These results show that rest interval length and age modulate the PEH effect after SIT.
The Adenovirus Vector Platform: Novel Insights into Rational Vector Design and Lessons Learned from the COVID-19 Vaccine

The adenovirus vector platform remains one of the most efficient toolboxes for generation of transfer vehicles used in gene therapy and virotherapy to treat tumors, as well as vaccines to protect from infectious diseases. The adenovirus genome and capsids can be modified using highly efficient techniques, and vectors can be produced at high titers, which facilitates their rapid adaptation to current needs and disease applications. Over recent years, the adenovirus vector platform has been in the center of attention for vaccine development against the ongoing coronavirus SARS-CoV-2/COVID-19 pandemic. The worldwide deployment of these vaccines has greatly deepened the knowledge on virus-host interactions and highlighted the need to further improve the effectiveness and safety not only of adenovirus-based vaccines but also of gene therapy and oncolytic virotherapy vectors. Based on the current evidence, we discuss here how adenoviral vectors can be further improved by intelligent molecular design. This review covers the full spectrum of state-of-the-art strategies to avoid vector-induced side effects ranging from the vectorization of non-canonical adenovirus types to novel genome engineering techniques.
Mediation effect of emotions on relational dynamics between entrepreneurs’ thinking processes and their entrepreneurial decision-making

ABSTRACT This study provides understanding as to how creative entrepreneurs’ thinking processes affect their entrepreneurial decision-making, and the influencing role played by their emotions. Using a cross-sectional design, quantitative data were collected from 576 creative entrepreneurs and analyzed descriptively and inferentially. It was found that creative entrepreneurs’ thinking processes affect their entrepreneurial decision-making. Their emotions were also found to strongly negatively affect their entrepreneurial decision-making. It was concluded that in understanding how the thinking processes of creative entrepreneurs inform their entrepreneurial decision-making, their emotional orientations, which strongly determine the character of their entrepreneurial decision-making, must be considered. The results of this study provide a good understanding of the dynamics of creative entrepreneurs’ thinking processes and their entrepreneurial decision-making and the mediating influence of their emotions, which could be used to effectively design creative entrepreneurship skills and practices toward improved entrepreneurial decision-making.
