Factors determining yield and quality of illicit indoor cannabis (Cannabis spp.) production

Judiciary currently faces difficulties in adequately estimating the yield of illicit indoor cannabis plantations. The latter data is required in penalization which is based on the profits gained. A full factorial experiment in which two overhead light intensities, two plant densities and four varieties were combined in the indoor cultivation of cannabis (Cannabis spp.) was used to reveal cannabis drug yield and quality under each of the factor combinations. Highest yield was found for the Super Skunk and Big Bud varieties which also exhibited the highest concentrations of Δ(9)-tetrahydrocannabinol (THC). Results show that plant density and light intensity are additive factors whereas the variety factor significantly interacts with both plant density and light intensity factors. Adequate estimations of yield of illicit, indoor cannabis plantations can only be made if upon seizure all factors considered in this study are accounted for.     

Relative Political and Value Proximity in Mediated Public Diplomacy: The Effect of State-Level Homophily on International Frame Building

This article applies the homophily thesis to public diplomacy and offers an empirical examination of a country's success in its mediated public diplomacy efforts. It analyzes international frame building, the process of creating or changing media frames in the international communications arena, by applying it to the case of Israeli mediated public diplomacy efforts during the war in Gaza in the winter of 2008–2009. The article claims that one way to use the homophily thesis in empirical analyses of international frame-building campaigns in conflicts is to measure the political and value proximity of a country promoting frames to other countries. Yet, proximity should be measured relatively rather than in absolute terms. Therefore, one should look not only at the dyadic proximity between two actors (i.e., Country A that attempts to promote its frames to Country C), but at the relative proximity between Countries A and C considering the proximity between the rival Country B and the target Country C. The study proposes a model and a method to facilitate empirical analysis of this claim. Using sophisticated computerized content analysis, our analyses demonstrate that relative proximity is related to successful international frame building in the hypothesized direction: The closer the relative proximity between Israel and a foreign country, the greater the acceptance of Israel's views.

Going online. Does ICT enabled-participation engage the young in local governance?

Local governments increasingly use online strategies to strengthen political participation of citizens in policy and politics. Young people, however, are generally under-represented. This article studies age patterns of participation across offline and online forms of action to test whether online initiatives are able to overcome this age bias. We first report a case study of online and offline problem reporting to local authorities. We find that simply going from offline to online participation reinforces rather than mitigates age bias. We then report a case study of message posting on an online political forum. In this case, age bias disappears. In contrast to the traditional instrumental modes, a forum is an expressive form of online participation. The young seem to value the act of participating over the outcomes of participation. For practice, these findings suggest a need for participation policies that speak to these expressive needs of young. In recent years, social media have reinforced the potential for expressive participation.     

Why monarchy persists in small states: the cases of Tonga,Bhutan and Liechtenstein

Monarchical rule is said to have become anachronistic in a modern age of legal rational orders and representative institutions. And yet, despite successive waves of democratization having usurped their authority across much of the globe, a select few monarchs remain defiant, especially in small states. This stubborn persistence raises questions about the application of Huntington’s “King’s Dilemma” in which modern monarchs are apparently trapped in a historical cycle that will ultimately strip them of meaningful power. Drawing on in-depth historical research in three small states that have sought to combine democratic and monarchical rule – Tonga, Bhutan, and Liechtenstein – we argue that, contra Huntington, monarchs in small states are neither doomed to disappear nor are they likely to be overwhelmed by the dilemma posed by modernist development. The lesson is that the size of political units is a critical variable too often overlooked in existing studies.     

How policies become contested: a spiral of imagination and evidence in a large infrastructure project

This article investigates how framing processes lead to polarization in the public debate on a large infrastructure project. Drawing on an analysis of newspaper articles about the “Oosterweel connection” in Antwerp (Belgium), it concludes that imaginative framing (appeals to emotions via symbolic language) and framing through evidence (appeals to rationality via factual language) mutually reinforce each other. Because of the mutual reinforcement, we talk of a spiralling motion. When evidence backs up appeals to the imagination, such as when facts back up metaphors, these appeals are endowed with authority and hence legitimacy. While this strengthens appeals that have been “proven” to be true, it also makes actors backing these appeals increasingly frustrated with other parties that still refuse to accept them. Because of their frustration, the former are spurred to launch new imaginative appeals conveying their anger and to seek new evidence to substantiate these new appeals. Going back and forth between imaginative appeals and appeals to evidence, all parties in a conflict develop their own vision of the contested issue and their own evidence base for the policy position. Over time, their tolerance for ambiguity decreases and the debate polarizes.     

Persistent Retinal Iron in Abusive Head Trauma

Retinal hemosiderin deposition is a histologic indicator of sustained hemorrhage but cannot be used to precisely estimate the elapsed time since an episode of trauma. A 5‐month‐old male infant was admitted to hospital after acute deterioration. Examination revealed encephalopathy, subdural hematomas, and retinal hemorrhages consistent with abusive head trauma (AHT). At the age of 3, he was readmitted to hospital with spontaneous osteopenic fracture of the right femur. The patient deteriorated and died after unsuccessful resuscitation. Ophthalmopathological investigation showed atrophy of the retina and optic nerve and hemosiderin deposition in both eyes. Retinal hemosiderin deposition is currently generally assumed to disappear within 6–8 weeks after the occurrence of hemorrhage in AHT. This case report describes an infant with bilateral retinal hemosiderin depositions due to hemorrhages sustained from AHT occurring 32 months prior to death. Implications of this finding for the interpretation of retinal hemosiderin depositions in AHT are discussed.
