Abstract Context: Key to understanding forest water balances is the role of tree species regulating evapotranspiration (ET), but the synergistic impact of forest species composition, topography, and water availability on ET and how this shapes drought sensitivity across the landscape remains unclear.Objectives: Our aims were to quantify (1) the effect of forest composition and topography including elevation and hillslope gradients on the relationship between ET and water availability, and (2) whether the relationship has changed over time. Methods: We used remotely sensed Landsat and MODIS ET to quantify forest ET across the Blue Ridge ecoregion of the southeastern USA. Then quantified metrics describing ET responses to water availability and trends in responses over time and assessed how these metrics varied across elevation, hillslope, and forest composition gradients. Results: We demonstrated forest ET is becoming less constrained by water availability at the expense of lateral flow. Drought impacts on ET diverged along elevation and hillslope gradients, and that divergence was more pronounced with increasingly severe drought, indicating high elevation and drier, upslope regions tend to maintain ET rates even during extreme drought. We identified a decoupling of ET from water availability over time, and found this process was accelerated at higher elevations and in areas with more diffuse-porous trees. Conclusions: Given the large proportion of forests on the landscape distributed across high elevation and upslope positions, reductions in downslope water availability could be widespread, amplifying vulnerability of runoff, the health of downslope vegetation, and aquatic biodiversity.

The aim of the study is to ascertain how the original Grotian formula ‘aut dedere aut punire’ has been implemented and evolved in international law. The first step is to classify the multilateral conventions that have accepted an aut dedere aut judicare clause. The goal is to bring out peculiarities of the different treaty texts, describing the relationship between the two options dedere and judicare, and the different obligations that arise for the contracting states. We will then examine the content of the two options, to define the legal boundaries within which the contracting states shall or may operate. At this point, we will focus on the legal nature of the aut dedere aut judicare principle that over time may have risen to the status of customary rule. The study will conclude with analysis of reactions to the breach of the aut dedere aut judicare clause by non-complying countries.

Abstract This article examines postmortem inventories and notarial records from Brazilian slaveholders in southern Brazil in the nineteenth century. By discussing selected cases in detail, it investigates the relationship between “precarious masters” (especially the poor and/or disabled, widows without family, and single elderly slaveholding women and men) and their slaves and former slaves to whom they bequeathed, in their testaments and final wills, manumission and property. The article reads these documents as intergenerational contractual arrangements that connected the masters’ expectations for care in illness and old age with the slaves’ and former slaves’ expectations for compensation for their work and dedication. Following these uneven relationships of interdependence and exploitation as they developed over time, the article suggests a reassessment of the role of paternalism in Brazil during the country’s final century of slavery. More than a tool to enforce relations of domination, paternalism articulated with the dynamics of vulnerability and interdependency as they changed over the life courses of both enslaved people and slave owners. This article shows how human aging became a terrain of negotiation and struggle as Brazilian slave society transformed throughout the nineteenth century.

Knowledge of the patterns of symptom distress in adults receiving treatment for lung cancer is an important first step in developing interventions that can potentially lessen symptom distress. The purposes of this secondary analysis were to describe the changes in patterns of symptom distress over time in adults receiving treatment for lung cancer, and to examine the relationship of selected demographic and clinical characteristics to symptom distress. Complete data were available for 117 patients. The patterns of symptom distress in adults receiving treatment for lung cancer varied between treatment groups and over time. Symptom distress scores were moderate to high on entry into the study, indicating that symptom management in newly diagnosed lung cancer patients is essential and should begin early in the course of illness. Moreover, clinical interventions should be tailored to the type of treatment. Various demographic and clinical variables were weak and inconsistent predictors of symptom distress, underscoring the importance of examining the role of psychosocial factors in mediating symptom distress.

The correlation between ideology and partisanship in the mass public has increased in recent decades amid a climate of persistent and growing elite polarization. Given that core values shape subsequent political predispositions, as well as the demonstrated asymmetry of elite polarization, this article hypothesizes that egalitarianism and moral traditionalism moderate the relationship between ideology and partisanship in that the latter relationship will have increased over time only among individuals who maintain conservative value orientations. An analysis of pooled American National Election Studies surveys from 1988 to 2012 supports this hypothesis. The results enhance scholarly understanding of the role of core values in shaping mass belief systems and testify to the asymmetric nature and mass public reception of elite cues among liberals and conservatives.

The last decades have witnessed a growing emphasis on the relationship between environmental law and criminal law. Legislation aimed at tackling environmental crime has been adopted at national,eu, and international level and has been gradually evolving over time. These developments notwithstanding, the current legal framework faces a number of challenges in tackling the largely inter-related phenomena of transnational, organised and economic environmental crime. This study of Valsamis Mitsilegas and Fabio Giuffrida addresses these challenges by focusing on the role of the European Union- and more specifically its criminal justice agencies (Europol and Eurojust)- in tackling transnational environmental crime. The study analyses the role of Eurojust and Europol in supporting and coordinating the competent national authorities dealing with investigations and/or prosecutions on transnational environmental crime, and it shows that, for the time being, the full potential of these agencies is not adequately fulfilled with regard to fighting this phenomenon effectively.

The lockdown resulting from coronavirus disease 2019 (COVID-19) has had a huge impact on peoples’ health. In sport specifically, athletes have had to deal with frustration of their objectives and changes in their usual training routines. The challenging and disruptive situation could hold implications for their well-being. This study examined the effect of the COVID-19 lockdown on changes in athletes’ reported eudaimonic well-being (subjective vitality) and goal motives (autonomous and controlled) over time (i.e., pre-lockdown and during lockdown). The relationship of resilience to changes in subjective vitality was also determined, and changes in athletes’ goal motives were examined as potential mediators. Participants were 127 Spanish university athletes aged between 18 and 34 years (M = 21.14; SD = 2.77). Approximately 4 months before the start of the lockdown in Spain (T1), athletes responded to a questionnaire assessing their resilience, goal motives, and subjective vitality. Around 6 months later into the lockdown period (T2), athletes’ goal motives and subjective vitality were assessed again. Growth modeling using hierarchical linear models revealed a significant decrease of autonomous goal motives and subjective vitality during the lockdown, but athletes did not show change over time in controlled goal motives. Path analysis, adjusting T2 measures for their corresponding T1 measures, showed that resilience significantly predicted changes in athletes’ autonomous goal motives, which then accounted for changes in subjective vitality. The indirect effect was significant. Resilience did not predict changes in athletes’ controlled goal motives. However, changes in controlled goal motives negatively predicted changes in subjective vitality during lockdown. The findings suggest negative impacts of the COVID-19 lockdown on athletes’ goal motives and eudaimonic well-being. Results also support the hypothesized mediational role of autonomous goal motives in the relationship between resilience and subjective vitality during the lockdown. As such, findings confirm the relevance of resilience to a key feature of athletes’ eudaimonic well-being and the importance of enhancing their autonomous goal striving.

PurposeSupervisory employees in the hotel industry experience high levels of emotional exhaustion. The current study aims to examine the impact of perceived manager support, perceived control over time and negative emotions at others on hotel supervisors' emotional exhaustion. It further investigates the mediating role of perceived control over time and negative emotions at others on the relationship between perceived manager support and hotel supervisors' emotional exhaustion.Design/methodology/approachPaper questionnaires were distributed at a hotel supervisor training seminar. A total of 155 usable responses were collected from hotel supervisors. Confirmatory factor analysis and structural equation modeling were used for hypotheses testing.FindingsResults showed that perceived manager support and perceived control over time both were negatively associated with hotel supervisors' emotional exhaustion. Negative emotions at others were positively related to hotel supervisors' emotional exhaustion. Both perceived control over time and negative emotions at others were found to mediate the relationship between perceived manager support and hotel supervisors' emotional exhaustion.Originality/valueThe study applied the job demand–resources model and the affective event theory to examine hotel supervisors' emotional exhaustion. The mediating role of perceived control over time and negative emotions at others added to the current knowledge of factors that are associated with hotel supervisory employees' emotional exhaustion.

This article develops a conceptual process model of how founders develop entrepreneurial ideas into opportunities. Drawing on translation theory, I conceptualise opportunity development as a process of translation between three interlinked but distinct entities over time: ostensive ideas (abstract entrepreneurial ideas), performative ideas (context-specific entrepreneurial ideas) and venture offerings. Whereas ostensive and performative ideas reside in the realm of conceptual and entrepreneurial thinking, venture offerings reside in actual business worlds and entrepreneurial action. The model identifies learning about the abstract nature of the entrepreneurial idea itself (ostensive) through lateral translation and abstraction and separates this from developing a concrete manifestation of the idea in time and space (performative) through vertical translation and concretisation. This is different from the venture offering, which is a specific empirical translation of the performative idea. Entrepreneurs receive feedback about the viability of the venture offering from social interaction that influence further opportunity development. The model portrays opportunity development as a triple-looped process driven by distinct types of translation, lateral, vertical and empirical. It clarifies the relationship between entrepreneurial ideas and entrepreneurial opportunities and maps the role of thinking and action in this regard.

Although cambial reactivation is considered to be strongly dependent on temperature, the importance of water availability at the onset of xylogenesis in semi-arid regions still lacks sufficient evidences. In order to explore how environmental factors influence the initiation of cambial activity and wood formation, we monitored weekly cambial phenology in Qilian juniper (Juniperus przewalskii) from a semi-arid high-elevation region of northwestern China. We collected microcores from 12 trees at two elevations during the growing seasons in 2013 and 2014, testing the hypothesis that rainfall limits cambial reactivation in spring. Cambium was reactivated from late April to mid-May, and completed cell division from late July to early August, lasting 70–100 days. Both sites suffered from severe drought from January to April 2013, receiving < 1 mm of rain in April. In contrast, rainfall from January to April 2014 was 5–6 times higher than that in 2013. However, cambial reactivation in 2014 was delayed by 10 days. In spring, soil moisture gradually increased with warming temperatures, reaching 0.15 m3/m3 before the onset of xylogenesis, which may have ensured water availability for tree growth during the rainless period. We were unable to confirm the hypothesis that rainfall is a limiting factor of cambial reactivation. Our results highlight the importance of soil moisture in semi-arid regions, which better describe the environmental conditions that are favorable for cambial reactivation in water-limited ecosystems.

Purpose – It has previously been noted that channel relationships are more richly understood when viewed over time. Moreover, there is a lack of research on how two types of satisfaction (economic and social satisfaction) have differential effects on partner trust over time. The purpose of this study is to investigate whether (and if so how) these two types of satisfaction have differential effects on partner trust from the initial stage of channel relationship to the subsequent relationship period. Design/methodology/approach – Longitudinal data are used in an effort to understand the dynamic process of channel relationships over time. Findings – It is found that over time, the strength of the relationship between economic satisfaction and partner trust decreases, while the effect of social satisfaction on partner trust increases. Interestingly, the direct effect of perceived value on partner trust dramatically decreases from time point T to T + 1, indicating that these relationships exhibit significant temporal effects. Research limitations/implications – The most relevant theoretical implication is that social satisfaction has a desirable role of bridging the relationship between perceived value and partner trust at time points T and T + 1. Thus, social satisfaction is a key factor in sustaining a channel partnership over time even after initial perceived value has been enhanced via the route of economic satisfaction. The main limitation is that data were collected in South Korea – further validation would require data from multiple cultural contexts. Practical implications – Results provide important implications for channel members aiming to enhance trust with partners. In initial stages of a relationship, channel members should concentrate their marketing resources on enhancing economic satisfaction, as it plays a key role in enhancing trust. As channel relationships evolve, the role of social satisfaction between perceived value and partner trust becomes more important. Thus, in the latter stages of a relationship, it would be prudent to focus more on activities which enhance social satisfaction. Originality/value – To the best of the authors’ knowledge, there is very little research focusing on temporal carryover effects. The authors thus contribute to the establishment and testing of temporal carryover effects of various business-to-business (B2B) relationship-related constructs, such as perceived value, economic and social satisfaction and partner trust.
