Twitter thou doeth?

Twitter, which started as a micro-blogging website, is the third most popular social network next to Facebook and My Space. Twitter is increasingly becoming primary means of communication among individuals and businesses. It is now being used in courts for issuing injunctions. However, Twitter “tweets” are also potential litigation minefield for lawyers, businesses and employers. As a social-networking tool, the use of Twitter can raise a variety of legal issues such as the right of publicity, breach of confidentiality, privacy infringement, fraud trademark infringement, copyright infringement, reverse username hijacking, among others.     

Paradoxes of (dis)empowerment in the postcolony: women,culture and social capital in Ghana

Women’s empowerment discourses in Africa involve contradictory desires from women on one hand and society at large on the other. This article argues that the traditional validation mechanisms for women’s identities are crucial avenues for analysing both the conceptions and experiences of empowerment. Drawing on primary ethnographic data, I analyse paradoxes in women’s empowerment discourses in postcolonial Ghanaian societies, where neoliberal discourses thrive side-by-side with collectivist–socialist cultural ideals. Using an example of social capital, gained largely through mothering, I suggest that, because women’s relationships with capital are structured by local socio-cultural and global economic structures and relations, the theorisation and application of the concept of empowerment need to recognise the complicated relationships (with capital) that women negotiate on a daily basis.     

Dynamics of change in internal policy advisory systems: the hybridization of advisory capacities in Germany

Recent scholarship on advisory systems has focussed on the externalization of advisory capacities and sectoral dynamics of change, whereas changes of internal policy advisory systems have not yet been approached systematically. This article proposes an analytical concept for exploring change dynamics in internal policy advisory systems by means of three logics for assessing policy advice (political salience, credibility and representativeness). The approach is illustrated by analysing changes within the internal policy advisory system of the German federal government (1990–2015). The analysis relies on three original datasets on ministerial departments, research agencies and governmental advisory bodies. We find that the internal advisory system of the German federal government is characterized by a differentiated hybridization of advisory logics, which has changed the nature of policy advice.

Comparing the legitimacy and effectiveness of global hard and soft law: An analytical framework

The international norms that are developed as tools of global governance can be placed on a continuum from traditional “hard law” treaties to the vaguest and voluntary “soft law.” In this article we develop an analytical framework for comparing norms on different positions along the continuum, thus for comparing international hard and soft law. We root the framework in both the rationalist and the constructivist paradigms of international relations by focusing on two overarching evaluative criteria: effectiveness and legitimacy. These broad concepts are divided into smaller building blocks encompassing mechanisms through which norms can exert influence; for example, by changing material incentives, identities, and building capacity, and by contributing to building source‐based, procedural, and substantive legitimacy. We illustrate the applicability of the framework with three norm processes of varying degrees of “softness” in global climate governance.     

Constructing ‘active citizenship’: single mothers,welfare, and the logics of voluntarism

Across welfare states, rights-based conceptions of citizenship are losing ground to obligation-centred notions. Drawing on in-depth longitudinal interviews with lone mothers receiving income assistance in British Columbia during a period of significant welfare reform, we explore the mothers' practices and narratives of volunteer labour in relation to conceptions of ‘active citizenship’. Volunteer work and the narratives women construct about it emerge as key sites of struggle and tension over the meaning of motherhood, work, and social contribution.     

Psychedelic fungus (Psilocybe sp.) authentication in a case of illegal drug traffic: sporological,molecular analysis and identification of the psychoactive substance

In nature, there are >200 species of fungi with hallucinogenic properties. These fungi are classified as Psilocybe, Gymnopilus, and Panaeolus which contain active principles with hallucinogenic properties such as ibotenic acid, psilocybin, psilocin, or baeocystin. In Chile, fungi seizures are mainly of mature specimens or spores. However, clandestine laboratories have been found that process fungus samples at the mycelium stage. In this transient stage of growth (mycelium), traditional taxonomic identification is not feasible, making it necessary to develop a new method of study.Currently, DNA analysis is the only reliable method that can be used as an identification tool for the purposes of supporting evidence, due to the high variability of DNA between species. One way to identify the species of a distinctive DNA fragment is to study PCR products analyzed by real time PCR and sequencing. One of the most popular sequencing methods of forensic interest at the generic and intra-generic levels in plants is internal transcribed spacer (ITS). With real time PCR it is possible to distinguish PCR products by differential analysis of their melting temperature (Tm) curves.This paper describes morphological, chemical, and genetic analysis of mycelia of psychedelic fungi collected from a clandestine laboratory. The fungus species were identified using scanning electron microscopy (SEM), mass spectrometry, HRM analysis, and ITS sequencing. The sporological studies showed a generally smooth surface and oval shape, with maximum length 10.1?μm and width 6.4?μm. The alkaloid Psilocyn was identified by mass spectrometry, while HRM analysis and ITS sequencing identified the species as Psilocybe cubensis. A genetic match was confirmed between the HRM curves obtained from the mycelia (evidence) and biological tissue extracted from the fruiting bodies. Mycelia recovered from the evidence and fruiting bodies (control) were genetically indistinguishable.
