This paper studies whether crony governance affects the logic behind governments’ targeting of violence, and how the deployment of violence allows politically connected firms to benefit from crony governance.  We address these issues in the context of the Argentine military junta that took power on March 24, 1976.  Specifically, we examine the logic driving the choice of firm level union representatives who were subjected to violence following the coup.  Using an original dataset assembled and digitized by us, we find that political, business and social connections to the regime are associated with an increase of 2 to 3 times in the number of firm level union representatives arrested and/or disappeared.  This is the case even after controlling for a battery of firms’ characteristics that capture alternative explanations for the targeting of violence.  The effect is particularly pronounced in privately owned (as opposed to state-owned) firms, suggesting that the correlation is driven by cronyism for financial gain rather than ideology or information transmission.  We also show that connected firms benefited from violence against union representatives by subsequently having less strikes and a higher market valuation.  Our findings highlight the pervasiveness of ties to the government, even in cases where one of the main stated goals of the regime is to curb cronyism.

Eric D. Gould and Esteban F. Klor. Working Paper. “Party Hacks and True Believers: The Effect of Party Affiliation on Political Preferences”.Abstract

This paper examines the effect of party affiliation on an individual’s political views.  To do this, we exploit the party realignment that occurred in the U.S. due to abortion becoming a more prominent and highly partisan issue over time.  We show that abortion was not a highly partisan issue in 1982, but a person’s abortion views in 1982 led many to switch parties over time as the two main parties diverged in their stances on this issue.  We find that voting for a given political party in 1996, due to the individual’s initial views on abortion in 1982, has a substantial effect on a person’s political, social, and economic attitudes in 1997.  These findings are stronger for highly partisan political issues, and are robust to controlling for a host of personal views and characteristics in 1982 and 1997.  As individuals realigned their party affiliation in accordance with their initial abortion views, their other political views followed suit.

“Nurse” honeybees tend brood around-the-clock with attenuated or no circadian rhythms, but the brood signals inducing this behavior remain elusive.  We first tested the hypothesis that worker circadian rhythms are regulated by brood pheromones. We monitored locomotor activity of individually isolated nurse bees that were either exposed to various doses of larval extracts or synthetic brood ester pheromone (BEP). Bees orally treated with larvae extracts showed attenuated circadian rhythms in one of four tested trials; a similar but statistically non-significant trend was seen in two an additional trial. Nurse bees treated with synthetic BEP showed rhythm attenuation in one of three trials. Next, we tested the hypothesis that capped brood, which does not require feeding, is nevertheless tended around-the-clock by nurse. By combining a new protocol that enables brood care by individually isolated nurse bees, detailed behavioral observations, and automatic high resolution monitoring of locomotor activity, we found that isolated nurses tended capped brood around-the-clock with attenuated circadian rhythms. Bees individually isolated in similar cages but without brood, showed strong circadian rhythms in locomotor activity and rest. This study shows for the first time that the need to feed hungry larvae is not the only factor accounting for around-the-clock activity in nurse bees. Our results further suggest that the transition between activity with and without circadian rhythms is not a simple switch triggered by brood pheromones. Around-the-clock tending may enhance brood development and health in multiple ways that may include improved larval feeding, thermoregulation and hygienic behavior.

The present study aims to describe existing peer-to-peer, social network-based sharing practices among adult students in teacher colleges.

Ubiquitous social network sites open up a wide array of possibilities for peer-to-peer information and knowledge sharing. College instructors are often unaware of such practices that happen behind the scenes.

An interpretative, qualitative research methodology was used. Thirty-seven Israeli students at a teacher college in Israel participated in either focus group discussions of (N = 29) or in-depth interviews (N = 8).

Whereas knowledge sharing has been a main focus of research in organizational and information sciences, its relevance to educational settings has thus far been underscored. Recent research shows that peer–to-peer knowledge sharing is widespread among teenage students. The current study extends that work to an adult student population.

The findings show thatknowledge sharing of this type is a common and even central feature of students' college life and study behavior. It takes place through a variety of small and larger social network-based peer groups of different formations, including mostly college students but at time also practicing, experienced teachers. Sharing groups are formed on the spot for short term purposes or are stable, continuous over longer time periods. The contents shared are predominantly lesson summaries, material for exams, reading summaries and lesson plans. They are used immediately or stored for future use, as students have access to vast data bases of stored materials that have been compiled throughout the years by students of previous cohorts. Teacher students mentioned a range of reasons for sharing, and overall regard it very positive. However, some downsides were also acknowledged (i.e., superficial learning, exclusion, attentional overload and interruptions).

College faculty and teaching staff should be cognizant and informed about these widespread peer-based knowledge sharing practices and consider whether perhaps changes in teaching formats and task assignments are required as a result.

Future research should extend this work to other higher education settings, cultures and countries, and should map the perceptions of higher education teaching staff about peer-to-peer, online knowledge sharing.

On Resonance: A study of culture-dependent reinterpretations of extremist violence in Israeli media discourse
Christian Baden and Yossi David. In Press. “On Resonance: A study of culture-dependent reinterpretations of extremist violence in Israeli media discourse.” Media, Culture & Society, 2017.Abstract

When and why do communities accept novel ideas as intuitively convincing? In the present study, we make use of the socio-cultural fragmentation of Israeli society to expose the discursive processes shaping the culture-dependent resonance of ideas. Specifically, we trace how Israeli president Reuven Rivlin’s interpretation of two lethal attacks by Jewish extremists on a Palestinian family and the Jerusalem Gay Pride Parade were received across Israel’s ultra-orthodox, settler, LGBT and Palestinian communities, as well as the mainstream right, center, and left. In a comparative analysis of media coverage catering to these groups, we distinguish six discursive responses to proposed ideas, which depend on their perception as plausible and appropriate given prior community beliefs. Our findings suggest a distinction between two possible meanings of resonance: Some ideas ‘click’ and are seamlessly appropriated in passing by a community, while others ‘strike a chord’ and raise a salient and emotional public debate.

The insect antennae receive olfactory information from the environment. In some insects it was shown that the antennal responsiveness is dynamically regulated by circadian clocks. However, it is unknown how general this phenomenon is and what functions it serves. Circadian regulation in honeybee workers is particularly interesting in this regard because they show natural task-related chronobiological plasticity. Forager bees show strong circadian rhythms in behavior and brain gene expression, whereas nurse bees tend brood around-the-clock and have attenuated circadian rhythms in activity and whole brain gene expression. Here we tested the hypothesis that there is task-related plasticity in circadian rhythms of antennal responsiveness to odorants in worker honeybees. We used electroantennogram (EAG) to measure the antennal responsiveness of nurses and foragers to general odorants and pheromones around the day. The capacity to track 10 Hz odorant pulses varied with time-of-day for both task-groups, but with different phases. The antennal pulse-tracking capacity was higher during the subjective day for the day-active foragers whereas it was better during the night for around-the-clock active nurses. The task-related phases of pulse-tracking rhythms were similar for all the tested stimuli. We also found evidence for circadian rhythms in the EAG response magnitude of foragers, but not of nurses. To the best of our knowledge, these results provide the first evidence for circadian regulation of antennal olfactory responsiveness and odorant pulse tracking capacity in bees, or any other hymenopteran insect. Importantly, our study shows for the first time that the circadian phase of olfactory responsiveness may be socially regulated.

How does the European Union integrate new values into the text of its treaties? A growing body of literature indicates that, in the past three decades, new norms and values have entered the EU's discourse, resulting in what is usually termed ‘normative power Europe’. Yet the research and knowledge to-date about the EU's discursive assimilation of new values and norms is surprisingly poor. As any institutional change, such integration has the potential to undermine the coherence of the EU's identity and thus also its objective to ‘speak with one voice’. This article explores the EU's discursive management of the continuity-versus-change imperative by analysing the integration of new values into the text of its treaties. This issue is addressed based on a quantitative content analysis on the full texts of European founding treaties between the 1950s and 2009. Findings show that the distribution of the EU's values in the text is not uniform: while the language of market economy and democracy is pervasive, the values of peace, European identity, rights and social justice are mentioned less frequently and in restricted linguistic environments. To account for the differences in the integration of values into the EU's treaty discourse, the article develops the notion of a discursive mechanism of differentiated value integration (MDVI). This rationale echoes the logic of differentiation in policy implementation employed by the EU. It is claimed here that, applied in the European discursive arena, MDVI allows radically different readings of the same text. This helps the EU to maintain a coherent value identity while at the same time enabling change.
