The present paper discusses findings from an empirical study looking into grammatical changes of Russian as the native language under the influence of English as a foreign language in a group of Russian-English bilinguals residing in the U.S. Twenty monolingual Russians and thirty Russian-English bilinguals participated in the study. All bilingual participants emigrated from Russia after their Russian language was fully acquired and had lived in the U.S. for 10-31 years prior to the time of the study. A semi-structured interview targeting autobiographical memories was employed as an elicitation technique. The analysis of narratives revealed distinctive changes in Russian in the two domains: word order and null subject use. The observed changes in the use of null pronominals suggested transfer from English. Bilinguals with more exposure to English used null pronominals less frequently. However, the directionality of effect in the use of the inverted word order by bilinguals was opposite to the predictions. Bilinguals with a very limited current exposure to Russian retained the inverted word order better than bilinguals with a broad exposure to Russian. Changes in the use of the inverted word order were partly attributed to the observed changes in the use of impersonal and existential sentences. The paper argues against cross-linguistic influence as the sole explanation of the first language changes.

Abstract Research suggests that bilinguals often outperform monolinguals on tasks that tap into executive functions, such as those requiring conflict resolution and cognitive flexibility. Recently, better attentional control has been detected in infants as young as 6 months, thereby providing a possible basis for a cognitive benefit before language production. The goal of the present study was to examine if cognitive flexibility is more advanced in bilingual infants. A detour reaching task assessing conflict resolution, a delayed response task assessing shifting, and a multiple location task assessing maintaining, were administered to 17-month-old infants. The main findings revealed that being bilingual did not improve performance on any of the executive function tasks. Furthermore, current exposure to a second language or language proficiency did not impact executive functioning. We conclude that a bilingual advantage in cognitive flexibility may not be present before children have enough experience in code switching.

Pesticides are linked to global insect declines, with impacts on biodiversity and essential ecosystem services. In addition to well-documented direct impacts of pesticides at the current stage or time, potential delayed “carryover” effects from past exposure at a different life stage may augment impacts on individuals and populations. We investigated the effects of current exposure and the carryover effects of past insecticide exposure on the individual vital rates and population growth of the solitary bee, Osmia lignaria. Bees in flight cages freely foraged on wildflowers, some treated with the common insecticide, imidacloprid, in a fully crossed design over 2 y, with insecticide exposure or no exposure in each year. Insecticide exposure directly to foraging adults and via carryover effects from past exposure reduced reproduction. Repeated exposure across 2 y additively impaired individual performance, leading to a nearly fourfold reduction in bee population growth. Exposure to even a single insecticide application can have persistent effects on vital rates and can reduce population growth for multiple generations. Carryover effects had profound implications for population persistence and must be considered in risk assessment, conservation, and management decisions for pollinators to mitigate the effects of insecticide exposure.

AbstractThe present study examines employees’ prior victimization from bullying in school or at work as a predictor of 1) their current exposure to negative social acts at work and 2) the likelihood of labelling as a victim of workplace bullying, and 3) whether the link between exposure to negative acts at work and the perception of being bullied is stronger among those who have been bullied in the past. We tested our hypotheses using a probability sample of the Norwegian working population in a prospective design with a 5-year time lag (N = 1228). As hypothesized, prior victimization positively predicted subsequent exposure to negative acts, which in turn was related to a higher likelihood of developing a perception of being a victim of workplace bullying. However, contrary to our expectations, prior victimization from bullying did not affect the relationship between current exposure to negative acts at work and the likelihood of self-labelling as a victim. Taken together, the results suggest that employees’ prior victimization is a risk factor for future victimization, yet overall plays a rather modest role in understanding current exposure to negative acts and self-labelled victimization from bullying at work.

Abstract The coronavirus disease 19 (COVID-19) pandemic is a disaster that has impacted lives globally. The purpose of this paper is to understand the linkage between the COVID 19 disaster and its impact on mental health of older people 70+. To reach this aim we reviewed the literature on disasters, COVID and mental conditions of older people (70+). The mental responses of the COVID disaster are multidimensional and potentially long-lasting. Rates of mental conditions of older persons vary widely due to exposure to COVID, country, population groups and methods used when conducting the study. We identified a multitude of factors contributing to mental conditions in older people, in general. We identified COVID-19 specific factors which have an impact such as threat to own life and threat to life of loved ones, interruption of behaviors and services, and physical as well as social isolation. Additionally, in older age, life events and feelings of being a burden contribute to mental conditions. To better understand the long impact of the COVID disaster on older people`s mental health we need to understand also the impact of past life events which may exacerbate the impact of the COVID disaster on mental conditions as well the impact of the current exposure to the pandemic.

The current exposure of species assemblages to high environmental variability may grant them resilience to future increases in climatic variability. In globally threatened coral reef ecosystems, management seeks to protect resilient reefs within variable environments. Yet, our lack of understanding for the determinants of coral population performance within variable environments hinders forecasting the future reassembly of coral communities. Here, using Integral Projection Models, we compare the short- (i.e., transient) and long-term (i.e., asymptotic) demographic characteristics of tropical and subtropical coral assemblages to evaluate how thermal variability influences the structural composition of coral communities over time. Exploring spatial variation across the dynamics of functionally different competitive, stress-tolerant, and weedy coral assemblages in Australia and Japan, we show that coral assemblages trade-off long-term performance for transient potential in response to thermal variability. We illustrate how coral assemblages can reduce their susceptibility towards environmental variation by exploiting volatile short-term demographic strategies, thus enhancing their persistence within variable environments. However, we also reveal considerable variation across the vulnerability of competitive, stress-tolerant, and weedy coral assemblages towards future increases in thermal variability. In particular, stress-tolerant and weedy corals possess an enhanced capacity for elevating their transient potential in response to environmental variability. Accordingly, despite their current exposure to high thermal variability, future climatic shifts threaten the structural complexity of coral assemblages, derived mostly from competitive coral taxa within highly variable subtropical environments, emulating the degradation expected across global coral communities.

In this paper we study the vulnerability management dimension in smart city initiatives. As many cities across the globe invest a considerable amount of effort, resources and budget to modernise their infrastructure by deploying a series of technologies such as 5G, Software Defined Networks and IoT, we conduct an empirical analysis of their current exposure to existing vulnerabilities. We use an updated vulnerability dataset which is further enriched by quantitative research data from independent studies evaluating the maturity and accomplishments of cities in their journey to become smart. We particularly focus on cities that aspire to implement a (data-driven) Circular Economy agenda which we consider to potentially yield the highest risk from a vulnerabilities exposure perspective. Findings show that although a smarter city is attributed with a higher vulnerability exposure, investments on technology and human capital moderate this exposure in a way that it can be reduced.
