Chi decide sulle norme tecniche? Un'analisi del dialogo tra istanze tecniche e istanze politiche nella formazione e applicazione delle norme tecniche

La tesi si propone l’obiettivo di indagare le modalità di interazione tra conoscenze tecnico-scientifiche e dato normativo, a partire dallo studio delle c.d. norme tecniche, ossia le norme, dotate di forza giuridica o meno, elaborate sulla base di conoscenze tecnico-scientifiche. La ricerca analizza diversi settori dell’ordinamento, accomunati da un’elevata influenza di saperi tecnici e al tempo stesso da un’indubbia rilevanza dal punto di vista costituzionale (la disciplina delle sperimentazioni cliniche dei farmaci, quella delle emissioni inquinanti di origine industriale e quella relativa agli standard di sicurezza dei prodotti), individuando quelle che al loro interno si possono considerare norme tecniche e mettendone in luce sia i profili formali (in quali atti-fonte sono contenute, quale natura giuridica presentano) che il procedimento di formazione, con particolare attenzione ai soggetti che vi prendono parte. Si propone quindi una sistematizzazione degli elementi emersi dall’indagine a partire da due diverse prospettive: in primo luogo tali dati vengono analizzati dal punto di vista dogmatico, individuando i diversi meccanismi di ingresso del dato tecnico-scientifico nel tessuto normativo (incorporazione nella norma giuridica, impiego di clausole generali, rinvio a norme extra-giuridiche), al fine di mettere in luce eventuali profili problematici per quanto riguarda il sistema delle fonti. La seconda prospettiva prende invece quale punto di riferimento il “centro di elaborazione sostanziale” delle norme considerate, al fine di evidenziarne i diversi fattori di legittimazione: a partire da esigenze di armonizzazione della disciplina e dall’assunto della neutralità delle conoscenze tecnico-scientifiche rispetto agli interessi coinvolti, l’elaborazione delle norme tecniche vede infatti un significativo ripensamento degli equilibri non solo fra attori pubblici e privati, ma anche tra legittimazione politica e legittimazione “tecnica” della scelta normativa. A tali aspetti è dedicata la parte conclusiva del lavoro, in particolare per quanto riguarda la conformità rispetto al disegno costituzionale.

Einfluss des Treg-Aktivierungsmarkers GARP auf die Differenzierung und Funktion von T-Zellen

CD4+CD25+FoxP3+ regulatorische T-Zellen (Treg) spielen eine essentielle Rolle bei der Unterdrückung von schädlichen Immunreaktionen. Da aktivierte CD4+ T-Helferzellen auch CD25 und FoxP3 exprimieren, können diese nicht als spezifische Marker zur Identifikation von Treg verwendet werden. Die Analyse der Membranproteinexpression beider Populationen führte zur Identifikation von GARP (glycoprotein A repetitions predominant) als spezifischer Marker auf aktivierten Treg. GARP bindet LAP und TGF-beta, welches für die Unterdrückung von entzündlichen T-Zellantworten von Bedeutung ist. Um die Funktion von GARP unabhängig von Treg zu untersuchen, wurde ein lösliches GARP Protein (sGARP) synthetisiert und sein Effekt auf die Aktivierung und Differenzierung von humanen T-Zellen untersucht. Die Ergebnisse zeigen, dass sGARP die Proliferation von naiven CD4+ T-Zellen supprimiert und zu einer Phosphorylierung von SMAD2/3 sowie zu der Induktion von FoxP3 führt. Zusätzlich inhibiert sGARP die Produktion von Effektorzytokinen wie IL-2 und IFN-gamma. Die Stimulation von naiven CD4+ T-Zellen mit sGARP induziert die Differenzierung zu Treg, welche in Kokultur die Aktivierung von T-Effektorzellen supprimieren. Die Wirkung war vergleichbar in naiven CD4+ und ruhenden CD4+CD45RA+ T-Zellen, konnte aber in differenzierten CD4+CD45RO+ T-Zellen nicht nachgewiesen werden. Die Induktion von FoxP3 und die Phosphorylierung von SMAD2/3 konnte durch eine Blockade des TGF-beta-Signalweges inhibiert werden. Dies lässt vermuten, dass die Funktion von sGARP zumindest teilweise von TGF-beta abhängig ist. Zusätzlich zu seiner passiven Rolle als TGF-beta-Transporter, induzierte sGARP die TGF-beta-Produktion in naiven T-Zellen und trägt so zum Mechanismus der infektiösen Toleranz bei. Des Weiteren fördert die Stimulation von sGARP in Anwesenheit von IL-6 und IL-23 die Differenzierung zu Th17 Zellen. rnNeben dem Einfluss von sGARP auf die Differenzierung von CD4+ T-Zellen, supprimiert sGARP die Proliferation und Granzyme B-Expression in CD8+ T-Zellen. rnFür die Analyse der immunmodulatorischen Funktion von sGARP in vivo wurde ein Modell einer xenogenen GvHD (graft-versus-host disease) verwendet. Der Transfer von humanen PBMC in neugeborene, immundefiziente Rag2-/-gamma-chain-/--Mäuse führt zu einer letalen GvHD, welche durch die Applikation von humanen Treg dosisabhängig unterdrückt werden kann. In diesem Modell konnte die repetitive Gabe von sGARP, ohne zusätzliche Zugabe von Treg, ebenfalls die GvHD unterdrücken. Dies lässt auf einen synergistischen Effekt von sGARP und Treg bei der Suppression inflammatorischer T-Zellantworten schließen. rnZusammengefasst lassen die Ergebnisse auf eine entscheidende Rolle von GARP in der Modulation der peripheren Toleranz folgern und zeigen sGARP als potentes Biological für die Behandlung von unerwünschten inflammatorischen Immunantworten.

Regulations on E-Commerce Consumer Protection Rules in China and Europe Compared – Same Same but Different?

This article provides a comprehensive overview of the regulations on e-commerce protection rules in China and the European Union. It starts by giving a general overview of different approaches towards consumer protection in e-commerce. This article then scrutinizes the current legal system in China by mainly focusing on SAIC’s “Interim Measures for the Administration of Online Commodity Trading and Relevant Service Activities”. The subsequent chapter covers the supervision of consumer protection in e-commerce in China, which covers both the regulatory objects of online commodity trading and the applied regulatory mechanisms. While the regulatory objects include operating agents, operating objects, operating behavior, electronic contracts, intellectual property and consumer protection, the regulatory mechanisms for e-commerce in China combines market mechanism and industry self-discipline under the government’s administrative regulation. Further, this article examines the current European legal system in online commodity trading. It outlines the aim and the scope of EU legislation in the respective field. Subsequently, the paper describes the European approach towards the supervision of consumer protection in e-commerce. As there is no central EU agency for consumer protection in e-commerce transactions, the EU stipulates a framework for Member States’ institutions, thereby creating a European supervisory network of Member States’ institutions and empowers private consumer organisations to supervise the market on their behalf. Moreover, the EU encourages the industry to self- or co-regulate e-commerce by providing incentives. Consequently, this article concludes that consumer protection may be achieved by different means and different systems. However, even though at first glance the Chinese and the European system appear to differ substantially, a closer look reveals tendencies of convergence between the two systems.

Online disclosure and privacy concerns: a study of Moroccan and American facebook users

In using online social networks to connect and interact with people has become extremely popular all around the world. Thelargest Social Networking Site (SNS), Facebook, offers its services in over 70 languages and increasingly relies oninternational users to grow its membership. Aiming to understand the role of culture in SNS participation, this study adopts a‘privacy calculus’ perspective to examine the differences in participation patterns between American and MoroccanFacebook users. Survey results show that Moroccans users disclose less on Facebook than US users, yet perceive moredamage should their privacy on Facebook be violated. American users, on the other hand, have lower privacy concerns, trustfellow SNS members and legal system more, and disclose more in their profile. From a practical standpoint, the resultsindicate that SNS providers cannot rely on the same methods to encourage user participation and disclosure in differentcountries.

Runaway and Throwaway Youth: Time for Policy Changes and Public Responsibility

The traditional American dream of owning a home, obtaining a college education, and working at a good, paying job is only that, a dream, for scores of homeless youth in America today. There is a growing street population of young people who have been thrown out of their homes by their caretakers or their families, and who face life-threatening situations each day. For these youth, the furthest thing in their lives is reaching the so-called “American Dream;” and their most immediate need is survival, simply living out the day in front of them. They have few options that lead to a decent and safe living environment. Their age, lack of work experience, and absence of a high school diploma make it most difficult to find a job. As a result, they turn to other means for survival; runaways and throwaways are most vulnerable to falling prey to the sex trade, selling drugs, or being lured into human trafficking, and some steal or panhandle. Street youth end up spending their nights in bus stations or finding a room in an abandoned building or an empty stairwell to sleep. Attempting to identify a specific number of homeless youth is difficult at best, but what is even more perplexing is our continued inability to effectively protect our children. We are left with a basic question framed by the fundamental tenets of justice: what is a community’s responsibility to its youth who, for whatever reason, end up living on the streets or in unsafe, abusive environments? The purpose of this paper is to briefly outline the characteristics of homeless youth, in particular differentiating between throwaways and runaways; explore the current federal response to homeless youth; and finally, address the nagging question that swirls around all children: can we aggressively aspire to be a community where every child is healthy and safe, and able to realize his or her fullest potential?

Prioritizing Healthy Child Development Could Prevent Child Prostitution

The CHILDREN AT RISK documentaries “Domestic Minor Sex Trafficking��� and “International Human Trafficking��� draw attention to the dire consequences of our failure as a society to ensure that all children are raised with healthy experiences in safe and loving environments. It is our collective responsibility to put policies and services into place to prevent child prostitution from happening in the first place, while also providing treatment and care for the victims of prostitution. We must embed the prevention of child prostitution into a broader vision for healthy child development and encourage our national, state, and local policymakers to prioritize the development and implementation of a comprehensive and coordinated strategy for children.
