Government expenditure and economic growth: a post-Keynesian analysis

ABSTRACT In a post-Keynesian growth model with positive saving propensity out of wages, this paper analyses the implication of different kinds of government expenditures on aggregate demand and economic growth. We distinguish between government expenditure on consumption and investment. The basic idea is that certain kinds of government investment expenditure influences labour productivity. In a formal model, we incorporate this idea by assuming labour productivity as an increasing function of government investment expenditure. When the economy is in a profit-led demand regime, under the balanced budget assumption, we show that a shift in government expenditure from consumption to investment leads to an unambiguous rise in both aggregate demand and economic growth. However, the result is ambiguous in the wage-led demand regime. Once the balanced budget assumption is dropped, while in a wage-led demand regime a rise in government investment expenditure may decrease aggregate demand and growth, it unambiguously raises both aggregate demand and growth in a profit-led demand regime. On the other hand, in the absence of a balanced budget assumption, a rise in government consumption expenditure has a positive effect in both regimes. We also show that allowing the government to run a deficit and incur debt does not necessarily lead to the public debt rising without bounds.
Organizing professional work and services through institutional complexity – how institutional logics and differences in organizational roles matter

How is the complexity of contemporary professional work and services organized differently by management at the strategic level and professionals at the operational level? And what are the implications for managing this complexity? Drawing on literatures on institutional complexity, organizational roles and the analyses of case study data from interviews, observations and documents at a large public service provider in Norway, this article advances the understanding of management in complex organizations and makes the following three contributions to the institutional logics literature. First, we show how multiple institutional logics have different functions at strategic and operational levels, resembling a dynamic interplay in organizing professional work and services. Second, we show how these differences in handling multiple logics are contingent upon the different roles of the strategic managers and operational professionals. Finally, we advance the understanding of what institutional complexity may involve in organizations by disclosing how the significant conflicts stem not only from the presence of multiple logics, but also from differences within the organizations in how multiple logics are handled. Our findings have implications for the planning and management of organizational design and implementation strategies and demonstrate the utility of the institutional complexity perspective for managing complexity in contemporary organizations.
Antibiotic resistance in agricultural soils: Source, fate, mechanism and attenuation strategy

Abstract Antibiotic resistance in agricultural soils is a significant environmental and health challenge worldwide. To minimize the risk of antibiotic resistance, it is important to understand the fate and spread mechanism of antibiotics and antibiotic resistance genes (ARGs), and develop effective technologies to minimize their negative effects. In this work, we reviewed recent studies on the occurrence of antibiotic resistance in soil by different agricultural practices. The continuous land applications of manures and sewage sludge, and irrigation with wastewater contribute to the elevated antibiotic resistance in soil. The fate of antibiotic resistance from different interfaces are also discussed. In particular, the mechanisms of ARGs dissemination between bacteria are presented. Aerobic composting, and anaerobic and aerobic digestions of manure, sludge, or wastewater are found to be effective treatments to reduce antibiotic resistance into agricultural soils from the sources. Furthermore, strategies to alleviate antibiotic resistance in soil are proposed, and research directions on in-depth mechanisms are outlined to elucidate the antibiotic resistance decay in soil treatment processes. Although much progress has been made in understanding the links of antibiotic resistance between soil and human health, there are still many unknowns on the complex interactions between them.

Real-time Price Discovery via Verbal Communication: Method and Application to Fedspeak

We advance the hypothesis and establish empirically that investors’ expectations adjust slowly to Central Banks’ messages. From the videos of post-FOMC-meeting press conferences, we extract the words, and timestamp them at the millisecond. We align the transcripts with high-frequency data for several financial assets to provide granular evidence on the investors’ expectations formation process. When the Chairman discusses the changes between current and previous policy statement, price volatility and trading volume spike dramatically, and prices move in the same direction as they did around the statement release. Our approach allows us to quantify in monetary terms the value of information rigidity.
Small-angle neutron scattering analysis of a water-based magnetic fluid with charge stabilization: contrast variation and scattering of polarized neutrons

Structure analysis of a magnetic fluid (nanoparticles of maghemite dispersed in water with charge stabilization and without surfactant) by means of small-angle neutron scattering is presented. A combination of the contrast variation technique and scattering of polarized neutrons was applied. In the first case, the scattering curves obtained for the unmagnetized fluid with variation of the heavy water content in the carrier are treated in terms of the basic functions approach. The almost homogeneous character of the nanoparticles with respect to the nuclear scattering length density makes it possible to separate information about their characteristic nuclear and magnetic radii. Polarized neutrons are then used to separate and analyze independently the nuclear and magnetic scattering contributions for the fully magnetized fluid. Both methods reveal a significant excess of the apparent nuclear size over the magnetic one, which is explained by a difference in the nonmagnetic and magnetic interactions in the system. The results indicate that from the viewpoint of magnetic interaction the studied fluid behaves under a magnetic field as a purely superparamagnetic system of independent particles. The magnetic scattering length density of the maghemite nanoparticles is found to be ∼25% less than the bulk value, which is in agreement with the data of the magnetization analysis.
Are the socioeconomic impacts associated with tropical cyclones in Mexico exacerbated by local vulnerability and ENSO conditions?

Tropical Cyclones (TCs) are among the most dangerous natural hazards because they can cause severe economic losses and high mortality. Climate risk is defined as a metric that depends on social vulnerability and the occurrence of natural hazards. A social vulnerability index was constructed for this study using two metrics: the degree of local marginalization and the local social gap. The accumulated rainfall and duration of extreme precipitation associated with TC passages are examined as a natural hazard during the period 1981–2017. TC days are depicted as days when TC‐related rainfall exceeded the 95th percentile of daily precipitation from May to November, defined as summer precipitation. In this way, changes in climate risk under El Niño‐Southern Oscillation (ENSO) conditions are explored to determine regions where both social vulnerability and TC days are high. These changes are useful to find out when disasters have more chances to occur. In the present study, climate risk was found to increase more than 80% from average in southwestern Mexico during strong El Niño years. Under neutral conditions, climate risk values rise to more than 40% than average over northwestern Mexico. Under strong La Niña conditions, climate risk increases by more than 80% from average over the eastern coast of Mexico. Our approach is validated through a comparison between anomalies in climate risk and disaster costs (socioeconomic impacts). Both local vulnerability and ENSO conditions exacerbate socioeconomic impacts associated with TCs, and an analysis of linear trends in TC rainfall and TC days reveals that most of the coastal regions in Mexico have a significant rising trend in both variables. Thus, Mexico should be prepared to face more TC extreme rainfall events. Suggestions for how Mexico can meet the objectives of international risk agendas are discussed.
Semelparity and Reproductive Death in Caenorhabditis elegans

In some species of salmon, reproductive maturity triggers the development of massive pathology resulting from reproductive effort, leading to rapid post-reproductive death. Such reproductive death, which occurs in many semelparous organisms (with a single bout of reproduction), can be prevented by blocking reproductive maturation, and this can increase lifespan dramatically. Reproductive death is often viewed as distinct from senescence in iteroparous organisms (with multiple bouts of reproduction) such as humans. Here we review the evidence that reproductive death occurs in C. elegans and discuss what this means for its use as a model organism to study aging. Inhibiting insulin/IGF-1 signaling and germline removal suppresses reproductive death and greatly extends lifespan in C. elegans, but can also extend lifespan to a small extent in iteroparous organisms. We argue that mechanisms of senescence operative in reproductive death exist in a less catastrophic form in iteroparous organisms, particularly those involving costly resource reallocation, and exhibiting endocrine-regulated plasticity. Thus, mechanisms of senescence in semelparous organisms (including plants) and iteroparous ones form an etiological continuum. Therefore understanding mechanisms of reproductive death in C. elegans can teach us about some mechanisms of senescence that are operative in iteroparous organisms.

A scoping review exploring ‘opportunity’ in occupational science: Possibilities for conceptual development

ABSTRACT The availability of and access to fair opportunities has been proposed as significant to promoting occupational justice. This paper presents a scoping review that aimed to explore how the concept ‘opportunity’ has been understood within occupational science. Following Arksey and O’Malley’s (2005) methodological framework, we identified, screened, and selected 12 papers that focused on the theorization of opportunity or concepts and/or frameworks proposed to be related. Our thematic synthesis of these papers revealed three themes: Opportunity conceptualized as synonymous with capabilities, Occupational opportunity conceptualized as an option to participate, and Implicit theorization of opportunity couched within social transformation. Collectively these themes revealed that theorization about opportunity is implicit and largely focused on access to basic resources. Opportunity was also shown to be a concept that holds importance for a socially transformative occupational science agenda because of the relationship it holds with situations of inequality and injustice. Although the third theme teases out some of the relationships that opportunity holds to other concepts relevant for social transformation, this theorization remains limited. We conclude that further scholarship should involve clarifying disciplinary terminology and providing insight into how opportunity could contribute to occupational justice. We end by providing some suggestions for how to take up this challenge.
Demonstration of ZnTe1-xOx Intermediate Band Solar Cell

We report the optical properties of ZnTe1-xOx (ZnTeO) and evidence for the photovoltaic (PV) activity of a ZnTeO intermediate band solar cell (IBSC). By photomodulated reflectance measurements, electron transitions from the intermediate band to the conduction band were demonstrated. The optical absorption coefficients for the electron transition from the valence band to the intermediate band exceeds 2×104 cm-1, suitable for thin-film PV device applications. The ZnTeO IBSC exhibits an enhanced spectral response below the band edge of ZnTe, and all results are consistent with the proposed conversion mechanism of IBSC.
Anatomical Study of Triangle of Brocq and Mouchet in Human Cadaveric Heart

Right and left coronary arteries maintain the nutritional supply of heart. The left coronary artery (LCA) bifurcates into Anterior Interventricular Artery (AIA) and Circumflex Artery (CA). Triangle of Brocq and Mouchet is an arterio-venous triangle formed by AIA and CA of left coronary artery and great cardiac vein (GCV) that lies between conus aretriosus and left auricle. This study aims to determine frequency of Brocq and Mouchet triangle and its anatomical details. This study was conducted in thirty formalin fixed cadaveric hearts collectively available in the Department of Anatomy, Nepal Medical College from November 2019 till April 2020. The incidence of heart showing the triangle was 93.3% with the most common type being closed which is followed by inferiorly opened, superiorly opened, and completely opened. Most frequent content of the triangle was median artery followed by diagonal branches of AIA and CA. the mean area of the triangle was 218.84mm2(527.97 mm2-57.26 mm2). The branches of LCA varied from bifurcation to pentafurcation. Relationship of GCV with AIA and CA was found to be either superficial or deep. The anatomical knowledge of the Brocq and Mouchet triangle regarding arterio-venous relationship will be required for angiographic procedures. Also, the triangle is a potential epicardial access route to mitral valve annulus thus detailed anatomical knowledge of the triangle will help cardiologist to achieve successful cardiological procedures with minimal complications.

High-speed droplet impingement on dry and wetted substrates

High-speed droplet impact is of great interest to power generation and aerospace industries due to the accrued cost of maintenance in steam and gas turbines. The repetitive impacts of liquid droplets onto rotor blades, at high relative velocities, result in blade erosion, which is known as liquid impingement erosion (LIE). Experimental and analytical studies in this field are limited due to the complexity of the droplet impact at such conditions. Hence, numerical analysis is a very powerful and affordable tool to investigate the LIE phenomenon. In this regard, it is crucial to understand the hydrodynamics of the impact in order to identify the consequent solid response before addressing the LIE problem. The numerical study of the droplet impingement provides the transient pressure history generated in the liquid. Determining the transient behavior of the substrate, in response to the pressure force exerted due to the droplet impact, would facilitate engineering new types of surface coatings that are more resistant to LIE. To that end, quantifying the impact pressure of compressible liquid droplets impinged at very high velocities, up to 500 m/s, on rigid solid substrates and liquid films is the main objective of the present work. A wide range of scenarios that commonly arise in the LIE problem are considered, i.e., droplet sizes between 200 µm and 1000 μm, impact velocities ranging from 100 m/s to 500 m/s, and liquid film thicknesses of 0 µm–200 μm. The maximum pressure exerted on the solid surface due to the droplet impact is calculated for both dry and wetted substrates. The results obtained from compressible fluid modeling are compared to those of other numerical studies and analytical correlations, available in the open literature. New correlations are developed for maximum impact pressure on rigid solids and liquid films that can be used to characterize the solid stress and estimate the lifetime of the material by carrying out the fatigue analysis.
Free riding, empire building, and cost management prior to and post municipal enterprise mergers in Japan

ABSTRACT Opportunistic overspending tendencies induce inflexible cost adjustments and encourage bad cost stickiness. To examine whether this perspective applies to public sector organizations (PSOs) and mergers, we test the asymmetric cost behaviors, (1) free riding and (2) empire building, associated with managerial incentives in merged Japanese municipal enterprises. Consequently, we find evidence that prior to mergers, administrators’ opportunistic spending originating from free-riding behavior affects cost stickiness; conversely, an analysis of the post-merger sample shows that the empire-building incentive might partly mitigate sticky costs. Our results corroborate the contradictory role of managerial discretion in resource adjustment decisions between pre- and post-mergers.
Reduced Ex Vivo Sensitivity of Post Artemether-Lumefantrine TreatmentRecurrent P. falciparum Isolates to Dihydroartemisinin and Piperaquine

Introduction: Since 2006, the Malian National Malaria Control Program (NMCP) adapted the Artemisinin based therapeutic combination (ATC) as the first line treatment molecule of uncomplicated malaria. Artemether + lumefantrine appears to be the most ACT used in Mali. However, recent studies reported increased recurrence of post AL treatment P. falciparum infections. Methods: Using the SYBR® Green fluorometric method of IC50 determination, we compared the sensitivity ex vivo of post AL recurrent and non-recurrent P. falciparum isolates to common antimalarial molecules. Results: Compared to non-recurrent, post AL treatment recurrent P. falciparum isolates harbored higher IC50’s values (geometric mean, number [Min-Max]) to dihydroartemisinin (0.87 nM, 68, [0.34 4 nM] vs 1.14 nM, 7, [0.34 6 nM]; P = 0.003) and piperaquine (15.8 nM, 74 [13 22.6 nM] vs 17.54 nM, 6 [4.5 40.2 nM]; P = 0.001). Recurrent and non-recurrent P. falciparum isolates showed similar IC50’s values with mefloquine (13.35 nM, 8 [1 28 nM] and 12.85 nM, 74 [4 36 nM]; P=0.29). The geometric mean IC50 to lumefantrine in recurrent isolates (14.52 nM, 8 [3 50.82 nM]) was higher than that of the non-recurrent isolates (9.9 nM, 71 [1 38.71 nM]) but the difference was not statistically significant (p = 0.53). The geometric mean IC50 to amodiaquine for recurrent isolates (24.75 nM, 73 [9 88 nM]) was higher than to non-recurrent isolates (22.92 nM, 6 [5 88 nM]), but the difference was not statistically significant (p = 0.09). Conclusion: Our study revealed a lower sensitivity of Post AL treatment recurrent P. falciparum isolates to dihydroartemisinin and piperaquine and a trend to higher sensitivity of those parasite to amodiaquine.
Testing the Independent and Joint Contribution of Exposure to Neurodevelopmental Adversity and Childhood Trauma to Risk of Psychotic Experiences in Adulthood

Abstract Exposure to neurodevelopmental adversity and childhood trauma are both independently associated with psychosis. However, there is little research on the mechanism underlying their relationship with each other. The current study investigated both the independent and joint effects of neurodevelopmental adversity and childhood trauma to better understand the etiology of psychosis. A large population-based cohort (N = 3514) followed from birth was assessed on psychotic experiences (PE) at 24 years. Neurodevelopmental adversity included obstetric complications (birth weight, gestational age, in-utero influenza exposure, resuscitation) and developmental impairment (cognitive and motor impairments). Trauma exposure included caregiver and peer inflicted trauma up to 17 years. Multiple regression models tested their independent and interactive effect on PE, and path analysis estimated the indirect effect of neurodevelopmental adversity on PE via trauma. Neurodevelopmental adversity (OR = 1.32, 95%CI: 1.08–1.62) and trauma (OR = 1.97, 95%CI: 1.65–2.36) independently increased the odds of PE. There was also an indirect relationship between neurodevelopmental adversity and PE via increased exposure to childhood trauma (β = 0.01, 95%CI: 0.004–0.024). In particular, peer bullying mediated the association between developmental impairment to PE (β = 0.02, 95%CI: 0.01–0.03). In conclusion, children with neurodevelopmental adversity, in particular those with developmental impairment, are more likely to be exposed to trauma. This new etiological understanding of psychosis suggests that PE may be partially modifiable through reducing exposure to peer bullying, especially in children with developmental impairment.
Effects of biochar application on greenhouse gas emissions, carbon sequestration and crop growth in coastal saline soil

To evaluate the benefits of application of biochar to coastal saline soil for climate change mitigation, the effects on soil organic carbon (SOC), greenhouse gases (GHGs) and crop yields were investigated. Biochar was applied at 16 t ha−1 to study its effects on crop growth (Experiment I). The effects of biochar (0, 3.2, 16 and 32 t ha−1) and corn stalk (7.8 t ha−1) on SOC and GHGs were studied using 13C stable isotope technology and a static chamber method, respectively (Experiment II). Biochar increased grain mass per plant of the wheat by 27.7% and increased SOC without influencing non‐biochar SOC. On average, 92.3% of the biochar carbon and 16.8% of corn‐stalk carbon were sequestered into the soil within 1 year. The cumulative emissions of CO2, CH4 and N2O were not affected significantly by biochar but cornstalk application increased N2O emissions by 17.5%. The global warming mitigation potential of the biochar treatments (−3.84 to −3.17 t CO2‐eq. ha−1 t−1 C) was greater than that of the corn stalk treatment (−0.11 t CO2‐eq ha−1 t−1 C). These results suggest that biochar application improves saline soil productivity and soil carbon sequestration without increasing GHG emissions.
