Outlier Loci Detect Intraspecific Biodiversity amongst Spring and Autumn Spawning Herring across Local Scales

Herring, Clupea harengus, is one of the ecologically and commercially most important species in European northern seas, where two distinct ecotypes have been described based on spawning time; spring and autumn. To date, it is unknown if these spring and autumn spawning herring constitute genetically distinct units. We assessed levels of genetic divergence between spring and autumn spawning herring in the Baltic Sea using two types of DNA markers, microsatellites and Single Nucleotide Polymorphisms, and compared the results with data for autumn spawning North Sea herring. Temporally replicated analyses reveal clear genetic differences between ecotypes and hence support reproductive isolation. Loci showing non-neutral behaviour, so-called outlier loci, show convergence between autumn spawning herring from demographically disjoint populations, potentially reflecting selective processes associated with autumn spawning ecotypes. The abundance and
exploitation of the two ecotypes have varied strongly over space and time in the Baltic Sea, where autumn spawners have faced strong depression for decades. The results therefore have practical implications by highlighting the need for specific management of these co-occurring ecotypes to meet requirements for sustainable exploitation and ensure optimal livelihood for coastal communities.

Media ‘Globalization’ as Survival Strategy for Authoritarian Regimes In the Arab Middle East

Sakr challenges the notion that transnational media technologies have forced states in the Arab Middle East to cede ever more control to non-state players since the 1990s. Taking account of a long history of foreign political engineering in Arab countries, she probes the realities of Arab broadcasting privatization, intra-regional harmonization of government communication policies, and external financial support for media freedom and reform, to show how Arab governments were large successfully in harnessing forces implicated in media globalization in a way that entrenched authoritarian elements of the status quo. The findings validate an alternative to globalization theory that places a dual focus on the agency of national ruling elites and the international structures that underpin the power of those elites today, as in the past.

Managerial Discretion in the Arab World: New National-Level Antecedents

Based on a sample of six Arabian countries, our study examines the effect of cultural practices on CEO discretion. Using a panel of senior consultants, we extend the national-level framework of managerial discretion and find that an encompassing array of cultural practices play a crucial role in shaping the degree of discretion provided to CEOs. We empirically demonstrate that power distance, future and performance orientation along with gender egalitarianism and assertiveness has positive relationships with managerial discretion. However, institutional collectivism, uncertainty avoidance and humane orientation negatively affect the degree of discretion provided to CEOs. As such, our results indicate that executives are able to take idiosyncratic and bold actions to the extent to which the cultural environment allows them to do so. Finally, we find new national-level antecedents of managerial discretion that haven’t been considered in earlier studies.
