Ukrainas konstitutionella sicksackande : Regimförändring och partiutveckling under semipresidentialism

Ukraine has repeatedly shifted between the two sub-types of semi-presidentialism, i.e. between premier-presidentialism and president-parliamentarism. The aim of this article is to discuss to what extent theoretical arguments against premier-presidential and president-parliamentary systems are relevant for understanding the shifting directions of the Ukrainian regime. As a point of departure, I formulate three main claims from the literature: 1) “President-parliamentarism is less conducive to democratization than premier-presidentialism.”; 2) “Semi-presidentialism in both its variants have built-in incitements for intra-executive conflict between the president and the prime minister.”; 3) “Semi-presidentialism in general, and president-parliamentarism in particular, encourages presidentialization of political parties.” I conclude from the study’s empirical overview that the president-parliamentary system– the constitutional arrangement with the most dismal record of democratization – has been instrumental in strengthening presidential dominance and authoritarian tendencies. The premier-presidential period 2006–2010 was by no means smooth and stable, but the presidential dominance weakened and the survival of the government was firmly anchored in the parliament. During this period, there were also indications of a gradual strengthening of institutional capacity among the main political parties and the parliament began to emerge as a significant political arena.

Demokrati eller presidentdiktatur? : Konstitutionella vägval i postkommunistiska länder

While authoritarian presidents prevail under heavily president-oriented constitutions throughout the post-Soviet region, democracy along parliamentary lines triumphs in Central Europe. This article discusses the constitutional pattern among the post-communist countries on the basis of two general questions: First, how can we explain why strong presidential constitutions dominate throughout the post-Soviet region whereas constrained presidencies and governments anchored in parliament have become the prevailing option in Central Europe? Second, and interlinked with the first question, why have so many post-communist countries (in the post-Soviet region as well as in Central Europe) chosen neither parliamentarism nor presidentialism, but instead semi-presidential arrangements whereby a directly elected president is provided with considerable powers and coexists with a prime minister? The analysis indicates that both historical-institutional and actor-oriented factors are relevant here. Key factors have been regime transition, pre-communist era constitutions and leaders, as well as short-term economic and political considerations. With differing strengths and in partly different ways, these factors seem to have affected the actors’ preferences and final constitutional compromises.

High female mortality resulting in herd collapse in free-ranging domesticated reindeer (Rangifer tarandus tarandus) in Sweden

Reindeer herding in Sweden is a form of pastoralism practised by the indigenous Sami population. The economy is mainly based on meat production. Herd size is generally regulated by harvest in order not to overuse grazing ranges and keep a productive herd. Nonetheless, herd growth and room for harvest is currently small in many areas. Negative herd growth and low harvest rate were observed in one of two herds in a reindeer herding community in Central Sweden. The herds (A and B) used the same ranges from April until the autumn gathering in October-December, but were separated on different ranges over winter. Analyses of capture-recapture for 723 adult female reindeer over five years (2007-2012) revealed high annual losses (7.1% and 18.4%, for herd A and B respectively). A continuing decline in the total reindeer number in herd B demonstrated an inability to maintain the herd size in spite of a very small harvest. An estimated breakpoint for when herd size cannot be kept stable confirmed that the observed female mortality rate in herd B represented a state of herd collapse. Lower calving success in herd B compared to A indicated differences in winter foraging conditions. However, we found only minor differences in animal body condition between the herds in autumn. We found no evidence that a lower autumn body mass generally increased the risk for a female of dying from one autumn to the next. We conclude that the prime driver of the on-going collapse of herd B is not high animal density or poor body condition. Accidents or disease seem unlikely as major causes of mortality. Predation, primarily by lynx and wolverine, appears to be the most plausible reason for the high female mortality and state of collapse in the studied reindeer herding community.
