The Influence of Accounting Information in the Re-Election of the Mayors in Portugal

The changes recommended by the New Public Management (NPM) in public accounting have given special attention and importance to the evaluation of mayor’s performance by citizens/voters. Thus, this study aims to assess the impact of accounting information on the re-election of Portuguese mayors. Taking the agency theory as a point of departure, we start from the following research question: Does the accounting information disclosed by the municipalities influence the re-election of Portuguese mayors? The research methodology used in this study is the quantitative type, through which a multivariate analysis of data was performed on 308 Portuguese municipalities, in the period 2005-2008, based on the election results of 2009. The results from the binary logistic regression show that some indicators of accounting nature have impact on the re-election of mayors in Portugal, namely, the components of financial accounting and municipal revenues.

Stress affects theta activity in limbic networks and impairs novelty-induced exploration and familiarization

Exposure to a novel environment triggers the response of several brain areas that regulate emotional behaviors. Here, we studied theta oscillations within the hippocampus (HPC)-amygdala (AMY)-medial prefrontal cortex (mPFC) network in exploration of a novel environment and subsequent familiarization through repeated exposures to that same environment; in addition, we assessed how concomitant stress exposure could disrupt this activity and impair both behavioral processes. Local field potentials were simultaneously recorded from dorsal and ventral hippocampus (dHPC and vHPC respectively), basolateral amygdala (BLA) and mPFC in freely behaving rats while they were exposed to a novel environment, then repeatedly re-exposed over the course of 3 weeks to that same environment and, finally, on re-exposure to a novel unfamiliar environment. A longitudinal analysis of theta activity within this circuit revealed a reduction of vHPC and BLA theta power and vHPC-BLA theta coherence through familiarization which was correlated with a return to normal exploratory behavior in control rats. In contrast, a persistent over-activation of the same brain regions was observed in stressed rats that displayed impairments in novel exploration and familiarization processes. Importantly, we show that stress also affected intra-hippocampal synchrony and heightened the coherence between vHPC and BLA. In summary, we demonstrate that modulatory theta activity in the aforementioned circuit, namely in the vHPC and BLA, is correlated with the expression of anxiety in novelty-induced exploration and familiarization in both normal and pathological conditions.
