The effects of biased technological change on total factor productivity: empirical evidence from a sample of OECD countries

Technological change is far from neutral. The empirical analysis of the rate and direction of technological change in a significant sample of 12 major OECD countries in the years 1970–2003 confirms the strong bias of new technologies. The paper implements a novel methodology to identify and disentangle the effects of the direction of technological change upon total factor productivity (TFP) and shows how the introduction of new and biased technologies affects the actual levels of TFP according to the relative local endowments. The empirical evidence confirms that the introduction of biased technologies enhances TFP when its direction matches the characteristics of local factor markets so that locally abundant inputs become more productive. When the direction of technological change favours the intensive use of production factors that are locally scarce, the actual increase of TFP is reduced.     

Self‐harm Risk Among Adolescents and the Phenomenon of the “Blue Whale Challenge”: Case Series and Review of the Literature

The “Blue Whale Challenge” is a dangerous Internet phenomenon. As per media reports, it involves a series of life‐threatening tasks imposed by a “curator” to “players,” who must fulfill the whole list, and it ends with the suicide of the player. The authors report the data of five suspected cases of “Blue Whales” managed from January 2016 to December 2017 by the staff of a unit (the “Bambi Unit” of the Pediatric Hospital “Regina Margherita” of Turin, Italy) that is dedicated to the evaluation of suspected abused children. Then, they analyzed this data in the light of the literature regarding self‐harm. This comparison highlights the role of the Internet in the spreading of self‐harm behavior among vulnerable adolescents who are characterized by epidemiological, psychological, psychiatric, social, and cultural risk factors. In conclusion, the authors suggest a multidisciplinary and specialized approach in the evaluation of adolescents who committed self‐harm activities.     

Sudden death from tubercular myocarditis

Tuberculous myocarditis is a rare finding. We present the case of a 33-year-old woman who was in good health and who died suddenly at home. Autopsy and histopathologic examinations revealed granulamatous lesions in the myocardium, lungs, lymph nodes, liver, and spleen. No fast acid bacilli were demonstrated on histological examination. The presence of a Mycobacterium tuberculosis DNA complex was identified using a polymerase chain reaction (PCR) on formalin-fixed paraffin-embedded histological samples. An HIV test carried out on the blood obtained during the autopsy was negative according to the DNA amplification technique (PCR) and enzyme-linked immunosorbent assay serological test. We hypothesize that the mechanism of death was severe ventricular arrhythmia due to granulomatous proliferation in the structures of the interventricular septum.     

Forensic genetic analysis of insect gut contents

Entomological evidence is most often used for estimating the postmortem interval, but fly larvae can also be a source of vertebrate DNA. Forensic analysis of DNA recovered from a larva's gut can be used to identify what the larva had been feeding on. During our previous research studies, we used the same DNA extraction for the dual purpose of identifying the insect species and associating a maggot with its last meal. In our experience, we have encountered several situations where this method for associating a maggot with a corpse would have been useful, such as removal of remains from a suspected crime scene, an alternative food source is nearby the scene or the body, and a chain-of-evidence dispute. However, since maggot gut content analysis is a quite brand-new area of study, many of the limitations of the technique have not yet been explored. The results of our most recent research studies suggest that third-instar larvae actively feeding on the corpse can be considered the best source of human DNA, better than postfeeding or starved larvae. In this paper, the state of the art of forensic genetic analysis of maggot gut contents is reviewed.     

The enactment of public participation in rulemaking: A comparative analysis

This study analyzes the enactment of public participation in rulemaking within the European Union and the Organization of Economic Cooperation and Development countries. It relies on an original dataset of administrative procedural acts and administrative laws concerning the making of delegated legislation. As 12 out of 39 countries enacted a procedure of notification, publication, and consultation between 1995 and 2015, the study focuses on courts while controlling for other domestic institutional determinants of legislative adoption and countries’ interdependence. The empirical findings show that countries with a highly independent judiciary system are less likely to enact a comprehensive provision for public participation in rulemaking. This finding highlights a paradox, namely that political systems are more likely to adopt rulemaking to enhance democratic legitimacy if they are characterized by a judicial system that does not actively pursue the legality of rulemaking.     

The Popular Front for the Liberation of Palestine during the First Intifada: From Opportunity to Marginalization (1987–1990)

Abstract

In understanding the decline of the Popular Front for the Liberation of Palestine (PFLP), the analysis of its political agency allows the identification of a pattern of policy fluctuation that recurs throughout several critical phases of its trajectory. In this regard, the First Intifada is a case in point. The new geographical setting, the strong network of affiliated organizations and the more favourable balance of power with Fatah represented a major opportunity for the PFLP to revive its political initiative and increase its political weight. However, the PFLP was unable to grasp this opportunity due to its inconsistencies in confronting the main challenges posed by the Intifada, namely Fatah’s diplomatic agenda, the relations with the PFLP’s branch in the Territories, the fragmentation of the Palestinian Left and the rise of the Islamist movement. Resorting to a systematic study of the PFLP’s official publications and to interviews with former and current militants, this article identifies the pattern of policy fluctuation that transformed the First Intifada into a turning point in its weakening process. This pattern acquires further relevance since it illustrates the basic poles of tensions behind the fluctuation of the PFLP’s political conduct throughout the following decades.     

The Innovation Paradox in Southern Europe. Unexpected Performance During the Economic Crisis

The international crisis has exerted a strong impact on the National Innovation Systems (NIS) of three Southern European economies: Italy, Portugal and Spain. These countries represent interesting cases for analysing responses to the crisis because they show a sort of innovation paradox: despite the weakness of their institutional systems and the defensive policies developed by governments, some of their companies have nevertheless been able to innovate even during the hardest years of the recession. In order to shed light on this paradox, three matters are taken into account: the distinctive features of the South European National Innovation Systems; the behaviour of governments and companies; the ‘generative dynamics’ and the ‘creative processes’ that have taken place during the crisis.
