The reprise evidential conditional (REC) is nowadays not very usual in Catalan: it is restricted to journalistic language and to some very formal genres (such as academic or legal language), it is not present in spontaneous discourse. On the one hand, it has been described among the rather new modality values of the conditional. On the other, the normative tradition tended to reject it for being a gallicism, or to describe it as an unsuitable neologism. Thanks to the extraction from text corpora, we surprisingly find this REC in Catalan from the beginning of the fourteenth century to the contemporary age, with semantic and pragmatic nuances and different evidence of grammaticalization. Due to the current interest in evidentiality, the REC has been widely studied in French, Italian and Portuguese, focusing mainly on its contemporary uses and not so intensively on the diachronic process that could explain the origin of this value. In line with this research, that we initiated studying the epistemic and evidential future in Catalan, our aim is to describe: a) the pragmatic context that could have been the initial point of the REC in the thirteenth century, before we find indisputable attestations of this use; b) the path of semantic change followed by the conditional from a ‘future in the past’ tense to the acquisition of epistemic and evidential values; and c) the role played by invited inferences, subjectification and intersubjectification in this change.

European public sectors are particularly affected by the demographic challenge and an ageing and shrinking workforce. According to OECD statistics, over 30% of public employees of central government in 13 countries will leave during the next 15 years. Moreover, the public sector has as compared to the private sector to rely on a much older workforce, who will have to work longer in future. Against this background, European governments need to react and re-think major elements of current HR and organisational management in the public sector. Particularly the skills in age management should be improved in order to also maintain in future a highly productive, competent and efficient public sector and to ensure that public employees stay longer ‘employable’, ‘healthy’, ‘fit for the job’ and ‘up to the task’. The survey suggests some solutions by investing more in three priority areas in the field of HRM.

This study analyses the current picture and prospects for EU–Brazil relations in the political and security arenas. As actors experiencing relevant changes, albeit in different directions in their respective international status quo, the EU and Brazil have found some common ground for convergence at the macro level on some structural issues, such as the normative framework of a changing global order, the striving for a multipolar world and the relevance and desirability of multilateralism. At the same time, it is argued that they differ significantly as to the strategies pursued in the attainment of those shared interests, resulting in competing, or eventually divergent, policy preferences when addressing specific issues and developments at the international level, limiting the prospects for a deep mutual commitment and engagement in political and security dynamics at the global level.

In this joint EPC-FSD Policy Brief, Andrea Frontini and Eran Etzion assess the state of play and the future prospects of EU-Israel relations in the light of recent domestic and regional political developments. They argue that, despite frequent cacophony and recurring stalemates, the EU-Israel partnership still has the potential to pursue shared strategic objectives. The two sides have to realign their relations, taking into account new realities and common challenges in the Middle East and Northern Africa region, and the current state of the Middle East Peace Process. More careful differentiation and stronger prioritisation of the policy dossiers at stake are urgently needed. An autonomous but joined up review of the overall relationship, guided by courage, pragmatism and stronger strategic direction, is crucial in order to move ahead.

I will start by discussing some aspects of Kagitcibasi’s Theory of Family Change: its current empirical status and, more importantly, its focus on universal human needs and the consequences of this focus. Family Change Theory’s focus on the universality of the basic human needs of autonomy and relatedness and its culture-level emphasis on cultural norms and family values as reflecting a culture’s capacity for fulfilling its members’ respective needs shows that the theory advocates balanced cultural norms of independence and interdependence. As a normative theory it therefore postulates the necessity of a synthetic family model of emotional interdependence as an alternative to extreme models of total independence and total interdependence. Generalizing from this I will sketch a theoretical model where a dynamic and dialectical process of the fit between individual and culture and between culture and universal human needs and related social practices is central. I will discuss this model using a recent cross-cultural project on implicit theories of self/world and primary/secondary control orientations as an example. Implications for migrating families and acculturating individuals are also discussed.

Shipboard studies during Ocean Drilling Program Leg 187 (Australian Antarctic Discordance, AAD) suggested that there was no discernible coincidence between the interpreted age of rocks recovered and the intensity of alteration observed. Samples from the oldest sites occupied appeared to exhibit the least overall effects of alteration, and the intensity of alteration varied from site to site. Previous investigations of low-temperature alteration in oceanic basement samples have been restricted by the myopic perspective provided by single drill holes or dredge collections. Combining core samples from Leg 187 and dredge samples from the AAD collection at Oregon State University (USA) offers the unique opportunity to investigate mineral and bulk chemical changes attending alteration of basalt over a range of ages from 0 to 28 Ma. Results of this research indicate that there is a general increase in the intensity of alteration as the basalts age and mosve off axis, but that this relationship is somewhat veiled by the dominating control on alteration intensity dictated by variations in permeability.

Hydrobelts divide the global landmasses into eight hydrological regions with resolution of 0.5°, based primarily on the annual average temperature (T) and runoff (q). The interbelt differences were maximised and intrabelt variability minimise. These hydrobelts are decomposed on continents as 26 hydroregions. The main aim of the dataset is to provide a robust reporting scale that could be used in water-related issues. The spatial datafiles for both, hydrobelts and hydroregions, are provided as shp-files and ascii raster files with accompanied metadata.
