Classical theory of investment: panel cointegration evidence from 13 EU countries

In the realm of macroeconomic theory, it is well established that investment decisions play an instrumental role in the determination of the level of output and employment; nevertheless, little progress has been made in relation to the theoretical aspects of these decisions. This paper, inspired by the classical approach to capital accumulation as well as the Keynesian theory of effective demand, attempts to enhance our empirical understanding of what determines investment decisions by exploring profitability, financial as well as demand factors. In so doing, a ‘Fully Modified OLS’ panel cointegration framework, for a cluster of two distinct groups of EU countries classified as core and the peripheral economies, provides the platform upon which our econometric investigation takes place. The respective evidence generated from the estimation process is in line with the theoretical framework proposed in this paper

Blood transcriptional biomarkers for active pulmonary tuberculosis in a high-burden setting: a prospective, observational, diagnostic accuracy study.

BACKGROUND: Blood transcriptional signatures are candidates for non-sputum triage or confirmatory tests of tuberculosis. Prospective head-to-head comparisons of their diagnostic accuracy in real-world settings are necessary to assess their clinical use. We aimed to compare the diagnostic accuracy of candidate transcriptional signatures identified by systematic review, in a setting with a high burden of tuberculosis and HIV. METHODS: We did a prospective observational study nested within a diagnostic accuracy study of sputum Xpert MTB/RIF (Xpert) and Xpert MTB/RIF Ultra (Ultra) tests for pulmonary tuberculosis. We recruited consecutive symptomatic adults aged 18 years or older self-presenting to a tuberculosis clinic in Cape Town, South Africa. Participants provided blood for RNA sequencing, and sputum samples for liquid culture and molecular testing using Xpert and Ultra. We assessed the diagnostic accuracy of candidate blood transcriptional signatures for active tuberculosis (including those intended to distinguish active tuberculosis from other diseases) identified by systematic review, compared with culture or Xpert MTB/RIF positivity as the standard reference. In our primary analysis, patients with tuberculosis were defined as those with either a positive liquid culture or Xpert result. Patients with missing blood RNA or sputum results were excluded. Our primary objective was to benchmark the diagnostic accuracy of candidate transcriptional signatures against the WHO target product profile (TPP) for a tuberculosis triage test. FINDINGS: Between Feb 12, 2016, and July 18, 2017, we obtained paired sputum and RNA sequencing data from 181 participants, 54 (30%) of whom had confirmed pulmonary tuberculosis. Of 27 eligible signatures identified by systematic review, four achieved the highest diagnostic accuracy with similar area under the receiver operating characteristic curves (Sweeney3: 90·6% [95% CI 85·6-95·6]; Kaforou25: 86·9% [80·9-92·9]; Roe3: 86·9% [80·3-93·5]; and BATF2: 86·8% [80·6-93·1]), independent of age, sex, HIV status, previous tuberculosis, or sputum smear result. At test thresholds that gave 70% specificity (the minimum WHO TPP specificity for a triage test), these four signatures achieved sensitivities between 83·3% (95% CI 71·3-91·0) and 90·7% (80·1-96·0). No signature met the optimum criteria, of 95% sensitivity and 80% specificity proposed by WHO for a triage test, or the minimum criteria (of 65% sensitivity and 98% specificity) for a confirmatory test, but all four correctly identified Ultra-positive, culture-negative patients. INTERPRETATION: Selected blood transcriptional signatures met the minimum WHO benchmarks for a tuberculosis triage test but not for a confirmatory test. Further development of the signatures is warranted to investigate their possible effects on clinical and health economic outcomes as part of a triage strategy, or when used as add-on confirmatory test in conjunction with the highly sensitive Ultra test for Mycobacterium tuberculosis DNA.

A pilot study to understand feasibility and acceptability of stool and cord blood sample collection for a large-scale longitudinal birth cohort

BACKGROUND: Few data are available to guide biological sample collection around the time of birth for large-scale birth cohorts. We are designing a large UK birth cohort to investigate the role of infection and the developing immune system in determining future health and disease. We undertook a pilot to develop methodology for the main study, gain practical experience of collecting samples, and understand the acceptability of sample collection to women in late pregnancy. METHODS: Between February-July 2014, we piloted the feasibility and acceptability of collecting maternal stool, baby stool and cord blood samples from participants recruited at prolonged pregnancy and planned pre-labour caesarean section clinics at University College London Hospital. Participating women were asked to complete acceptability questionnaires. RESULTS: Overall, 265 women were approached and 171 (65%) participated, with ≥1 sample collected from 113 women or their baby (66%). Women had a mean age of 34 years, were primarily of white ethnicity (130/166, 78%), and half were nulliparous (86/169, 51%). Women undergoing planned pre-labour caesarean section were more likely than those who delivered vaginally to provide ≥1 sample (98% vs 54%), but less likely to provide maternal stool (10% vs 43%). Pre-sample questionnaires were completed by 110/171 women (64%). Most women reported feeling comfortable with samples being collected from their baby (<10% uncomfortable), but were less comfortable about their own stool (19% uncomfortable) or a vaginal swab (24% uncomfortable). CONCLUSIONS: It is possible to collect a range of biological samples from women around the time of delivery, and this was acceptable for most women. These data inform study design and protocol development for large-scale birth cohorts

Surreptitious symbiosis: engagement between activists and NGOs

Based on research conducted in Athens, Cairo, London and Yerevan the article analyses the relationship between activists engaged in street protests or direct action since 2011 and NGOs. It examines how activists relate to NGOs and whether it is possible to do sustained activism to bring about social change without becoming part of a ‘civil society industry’. The article argues that while at first glance NGOs seem disconnected from recent street activism, and activists distance themselves from NGOs, the situation is more complicated than meets the eye. It contends that the boundaries between the formal NGOs and informal groups of activists is blurred and there is much cross-over and collaboration. The article demonstrates and seeks to explain this phenomenon, which we call surreptitious symbiosis, from the micro- perspective of individual activists and NGO staff. Finally, we discuss whether this surreptitious symbiosis can be sustained and sketch three scenarios for the future

The role of celebrities in mediating distant suffering

How effective are celebrities, not just in helping to draw attention to distant suffering, but in actually regulating spectators’ mediated experiences of the lives of distant strangers? What function does the perceived authenticity of a celebrity play in their role as mediator? This article seeks to address such questions by analysing the results of an audience study involving two phases of focus groups separated by a two-month diary study. The results show that celebrities certainly help to shape our mediated experiences of distant suffering – but not always in the ways and to the extent we might expect. What is clear is that celebrities are generally ineffective in cultivating a cosmopolitan engagement with distant suffering

Stories of family caregivers of people with dementia in Greece: Implications for counselling [Histoires des soignants familiaux de personnes atteintes de démence en Grèce : implications pour la relation d’aide psychologique (counselling)] [Storie di assistenza familiare di persone con demenza in Grecia: implicazioni per il counselling - Phillia Issari] [HISTORIAS DE CUIDADORES EN FAMILIAS CON ALGUN MIEMBRO QUE SUFRE DE DEMENCIA EN GRECIA. IMPLICACIONES PARA LA ORIENTACION PSICOLOGICA]

A substantial body of literature has identified high rates of burden, psychological morbidity, social isolation, health and financial difficulties among dementia caregivers. The present qualitative study adopted an Interpretive Phenomenological Analysis approach in order to explore the lived experiences of dementia family caregivers within the Greek sociocultural context. The sample was purposive and consisted of 10 women dementia family caregivers from Athens and Thessaloniki. Individual in-depth interviews were conducted and analysed according to IPA. The participants’ personal accounts included themes related to ethical/existential and cultural aspects of family caregiving; changes in family relationships; impact of the caregiving experiences; sources of support and help seeking; positive and meaningful aspects of the care experience. The research findings are discussed in the context of Gilligan’s moral psychological theory, and cultural dimensions of family caregivers. Implications for counselling interventions aiming at supporting caregivers are presented. © 2017 Informa UK Limited, trading as Taylor &amp; Francis Group

Further evidence on the causal relationship between government spending and economic growth: The case of Greece, 1958–2004

The purpose of this paper is the empirical testing of the relationship between economic growth and government spending and, at the same time, to determine the extent to which economic growth causes growth in government expenditures (Wagner’s law) or the other way around (Keynesian hypothesis). The econometric analysis, using data for the Greek economy covering the period 1958–2004 and based on recent developments in the theory of cointegrated processes, reveals a long-run equilibrium relationship between government expenditures and economic output. Furthermore, the analysis detects causal effects in both the short-run and long-run horizon running from government expenditures to the level of economic activity and vice versa
