Previous research has demonstrated the efficacy of psychological interventions to foster resilience. However, little is known about whether the cultural context in which resilience interventions are implemented affects their efficacy on mental health. Studies performed in Western (k = 175) and Eastern countries (k = 46) regarding different aspects of interventions (setting, mode of delivery, target population, underlying theoretical approach, duration, control group design) and their efficacy on resilience, anxiety, depressive symptoms, quality of life, perceived stress, and social support were compared. Interventions in Eastern countries were longer in duration and tended to be more often conducted in group settings with a focus on family caregivers. We found evidence for larger effect sizes of resilience interventions in Eastern countries for improving resilience (standardized mean difference [SMD] = 0.48, 95% confidence interval [CI] 0.28 to 0.67; p < 0.0001; 43 studies; 6248 participants; I2 = 97.4%). Intercultural differences should receive more attention in resilience intervention research. Future studies could directly compare interventions in different cultural contexts to explain possible underlying causes for differences in their efficacy on mental health outcomes.
Eight new Neotropical species of Dexosarcophaga Townsend, 1917 are described, five from Brazil, Dexosarcophaga phoenix sp. nov., Dexosarcophaga jandainae sp. nov., Dexosarcophaga patiuorum sp. nov., Dexosarcophaga petra sp. nov., and Dexosarcophaga sphaera sp. nov., one from Costa Rica, Dexosarcophaga limon sp. nov., one from Ecuador, Dexosarcophaga napo sp. nov., and one from Colombia, Dexosarcophaga pallida sp. nov. Male and female morphology is documented with photographs and illustrations, including details of the male terminalia for all new species and female terminalia of Dexosarcophaga phoenix sp. nov. and Dexosarcophaga sphaera sp. nov. With the addition of these new species, 58 species of Dexosarcophaga are now known, with records from the American continent spanning from the southern United States to northern Argentina.
The first case of COVID-19 infection in Africa was recorded in Egypt on 14 February 2020. Following this, several projections of the possible devastating effect that the virus can have on the population of African countries were made in the Western media. This paper presents evidence for Africa’s successful responses to the COVID-19 pandemic and under-reporting or misrepresentation of these successes in Western media. It proceeds to argue for accounting for these successes in terms of Africa’s communitarian way of life and conceptions of self, duty, and rights; and that a particular orientation in theorizing on global justice can highlight the injustices inherent in the misrepresentation of these successes and contribute shared perspectives to formulating a framework of values and concepts that would facilitate the implementation of global policy goals for justice. The paper is thus grounded in a rejection of the insular tenets of theorizing prevalent in the global justice debate and to persistent inclinations in Western scholarship to the thinking that theorizing in the African context that draws inspiration from the cultural past has little to contribute to the quest for justice globally. On the contrary, it argues that reflexive critique of cultural history is a necessary source of normative ideals that can foster tolerant coexistence and a cooperative endeavour toward shared conceptions of justice in the contemporary world.
This paper considers ways in which rulers can respond to, generate, or exploit fear of COVID-19 infection for various ends, and in particular distinguishes between ‘fear-invoking’ and ‘fear-minimising’ strategies. It examines historical precedent for executive overreach in crises and then moves on to look in more detail at some specific areas where fear is being mobilised or generated: in ways that lead to the suspension of civil liberties; that foster discrimination against minorities; and that boost the personality cult of leaders and limit criticism or competition. Finally, in the Appendix, we present empirical work, based on the results of an original survey in Brazil, that provides support for the conjectures in the previous sections. While it is too early to tell what the longer-term outcomes of the changes we note will be, our purpose here is simply to identify some warning signs that threaten the key institutions and values of democracy.
We live in tragic times. Millions are sheltering in place to avoid exacerbating the Coronavirus (COVID-19) pandemic. How should we respond to such tragedies? This paper argues that the human right to health can help us do so because it inspires human rights advocates, claimants, and those with responsibility for fulfilling the right to try hard to satisfy its claims. That is, the right should, and often does, give rise to what I call the virtue of creative resolve. This resolve embodies a fundamental commitment to finding creative solutions to what appear to be tragic dilemmas. Contra critics, we should not reject the right even if it cannot tell us how to ration scarce health resources. Rather, the right gives us a response to apparent tragedy in motivating us to search for ways of fulfilling everyone’s basic health needs.
The COVID-19 pandemic is affecting countries across the globe. Only a globally coordinated response, however, will enable the containment of the virus. Responding to a request from policy makers for ethics input for a global resource pledging event as a starting point, this paper outlines normative and procedural principles to inform a coordinated global coronavirus response. Highlighting global connections and specific vulnerabilities from the pandemic, and proposing standards for reasonable and accountable decision-making, the ambition of the paper is two-fold: to raise awareness for the justice dimensions in the global response, and to argue for moving health from the periphery to the centre of philosophical debates about social and global justice.
The COVID-19 pandemic has both highlighted and exacerbated global health inequities, leading for calls for responses to COVID to promote social justice and ensure that no one is left behind. One key lesson to be learnt from the pandemic is the critical importance of decolonizing global health and global health research so that African countries are better placed to address pandemic challenges in contextually relevant ways. This paper argues that to be successful, programmes of decolonization in complex global health landscapes require a complex three-dimensional approach. Drawing on the broader discourse of political decolonization that has been going on in the African context for over a century, we present a model for unpacking the complex task of decolonization. Our approach suggests a three-dimensional approach which encompasses hegemomic; epistemic; and commitmental elements.
Introduction

The present status in the field of strange mesons in nuclei and neutron stars is reviewed. In particular, the K̅N interaction, that is governed by the presence of the Λ(1405), is analyzed and the formation of the K̅NN bound state is discussed. Moreover, the properties of K̅ in dense nuclear matter are studied, in connection with strangeness production in nuclear collisions and kaon condensation in neutron stars.
We address the modification of open heavy-flavor mesons in a hot medium of light mesons within an effective theory approach consistent with chiral and heavy-quark spin-flavor symmetries and the use of the imaginarytime formalism to introduce the non-zero temperature effects to the theory. The unitarized scattering amplitudes, the ground-state self-energies and the corresponding spectral functions are calculated self-consistently. We use the thermal ground-state spectral functions obtained with this methodology to further calculate 1) open-charm meson Euclidean correlators, and 2) off-shell transport coefficients in the hadronic phase.
The bee genus Austrosphecodes Michener, 1978 comprises 29 obligatory cleptoparasitic species distributed from Chile to Mexico. Currently, three species are known to occur in Brazil, Austrosphecodes brasiliensis (Schrottky, 1910), A. inornatus (Schrottky, 1902), and A. minarum (Schrottky, 1910). Here, we describe nine new species, Austrosphecodes asmodeus sp. nov., A. balrog sp. nov., A. cerberus sp. nov., A. gorgon sp. nov., A. jurupari sp. nov., A. krampus sp. nov., A. lucifer sp. nov., A. orcus sp. nov., and A. tartarus sp. nov. An identification key for the 12 known species from Brazil is presented. Specimens of A. asmodeus sp. nov. and A. brasiliensis were observed near nest aggregations of Caenohalictus incertus (Schrottky, 1902) in Curitiba (State of Paraná).
We present the first measurement of event-by-event fluctuations in the kaon sector in Pb – Pb collisions at √sNN = 2.76 TeV with the ALICE detector at the LHC. The robust fluctuation correlator νdyn is used to evaluate the magnitude of fluctuations of the relative yields of neutral and charged kaons, as well as the relative yields of charged kaons, as a function of collision centrality and selected kinematic ranges. While the correlator νdyn[K+,K−] exhibits a scaling approximately in inverse proportion of the charged particle multiplicity, νdyn[K0 S ,K±] features a significant deviation from such scaling. Within uncertainties, the value of νdyn[K0 S ,K±] is independent of the selected transverse momentum interval, while it exhibits a pseudorapidity dependence. The results are compared with HIJING, AMPT and EPOS–LHC predictions, and are further discussed in the context of the possible production of disoriented chiral condensates in central Pb – Pb collisions.
Plagiognathus ozgurkocaki sp. nov. is described based on a long series of specimens from Karaman, Turkey. The new species is remarkable among its congeners in Palearctic Region due to the combination of following characters: remarkably small size, dense and unicolorous pale yellow vestiture, darkened cuneus and yellow first antennal segment with a basal ring and pre-apical dots. The new species is associated with the endemic Phlomis leucophracta P.H.Davis & Hub.-Mor. (Lamiaceae) which makes it unique among all its congeners. Additionally, Plagiognathus bipunctatus albicans (Reuter, 1901) and Plagiognathus marivanensis Linnavuori, 2010 are recorded from Karaman, former constitutes a new record for Turkey.
In March 2019 the HADES experiment recorded 14 billion Ag+Ag collisions at √SNN = 2.55 GeV as a part of the FAIR phase-0 physics program. With the capabilities to measure and analyze particles forming the bulk matter, namely pions, protons and light nuclei, as well as rare probes like dilepton decays of vectormesons and strange hadrons, the HADES experiment allows to study the properties of matter at high densities in great detail. In this contribution a special focus is put on the reconstruction of weakly decaying strange hadrons.
Probing the association between resting-state brain network dynamics and psychological resilience
(2022)
Abstract
This study aimed at replicating a previously reported negative correlation between node flexibility and psychological resilience, that is, the ability to retain mental health in the face of stress and adversity. To this end, we used multiband resting-state BOLD fMRI (TR = .675 sec) from 52 participants who had filled out three psychological questionnaires assessing resilience. Time-resolved functional connectivity was calculated by performing a sliding window approach on averaged time series parcellated according to different established atlases. Multilayer modularity detection was performed to track network reconfigurations over time, and node flexibility was calculated as the number of times a node changes community assignment. In addition, node promiscuity (the fraction of communities a node participates in) and node degree (as proxy for time-varying connectivity) were calculated to extend previous work. We found no substantial correlations between resilience and node flexibility. We observed a small number of correlations between the two other brain measures and resilience scores that were, however, very inconsistently distributed across brain measures, differences in temporal sampling, and parcellation schemes. This heterogeneity calls into question the existence of previously postulated associations between resilience and brain network flexibility and highlights how results may be influenced by specific analysis choices.
Author Summary
We tested the replicability and generalizability of a previously proposed negative association between dynamic brain network reconfigurations derived from multilayer modularity detection (node flexibility) and psychological resilience. Using multiband resting-state BOLD fMRI data and exploring several parcellation schemes, sliding window approaches, and temporal resolutions of the data, we could not replicate previously reported findings regarding the association between node flexibility and resilience. By extending this work to other measures of brain dynamics (node promiscuity, degree) we observe a rather inconsistent pattern of correlations with resilience that strongly varies across analysis choices. We conclude that further research is needed to understand the network neuroscience basis of mental health and discuss several reasons that may account for the variability in results.
The paper proposes a comprehensive analysis of the paragraph which Biton, in his work known under the title Construction of Machines of War and Catapults, dedicates to the explanation of the so called σαμβύκη, a kind of scaling ladder on wheels designed by Damios of Kolophon. On the basis of both mechanical and textual considerations the κοχλίας, whose revolving movement produces the oscillation of the ladder, should be interpreted as a cylindrical horizontal roller (like Marsden suggests) and not as a vertical screw (like Lendle thinks). Accordingly, the supporting structure of the machine should be understood much less massive than what has been thought by scholars after Marsden.
After briefly reviewing the state of theoretical knowledge related to the behavior of the ϕ meson in nuclear matter, preliminary results of transport simulations of pA reactions corresponding to the KEK E325 experiment are presented. Finally, an outlook to current and future developments in the field is given.
The status of five genera recognized within subfamily Buccininae (Buccinidae) is critically re-assessed based on the molecular phylogenetic analysis of the cox-1, 16S, and 28S gene fragments. Our results suggest restoring Volutharpa P. Fischer, 1856 from synonymy of Buccinum and we also consider Plicibuccinum Golikov & Gulbin, 1977 as valid genus. New molecular data provide further support for the synonimization of Bathybuccinum Golikov & Sirenko, 1988 with Buccinum Linnaeus, 1758. Furthermore, our data demonstrate that Thysanobuccinum Golikov #38; Gulbin in Golikov, 1980 and Ovulatibuccinum Golikov & Sirenko, 1988 as currently construed are nested within Buccinum and their subgeneric rank is not confirmed. Therefore, we synonymize these genera with Buccinum. In the absence of molecular data the monotypic genus Corneobuccinum Golikov & Gulbin, 1977 is provisionally considered valid. Two new species, Buccinum hasegawai sp. nov. and B. bizikovi sp. nov. are described from the Kurile Islands; these species were previously erroneously identified as Bathybuccinum bombycinum (Dall, 1907) and Ovulatibuccinum ovulum (Dall, 1907), respectively. New replacement names are proposed for the secondary junior homonym Buccinum perlatum (Fraussen & Chino, 2009) and the primary junior homonyms Buccinum coronatum Golikov, 1980 and Buccinum costatum Golikov 1980.
