Functional anatomy of human eyeblink conditioning determined with regional cerebral glucose metabolism and positron-emission tomography.

Relative cerebral glucose metabolism was examined with positron-emission tomography (PET) as a measure of neuronal activation during performance of the classically conditioned eyeblink response in 12 young adult subjects. Each subject received three sessions: (i) a control session with PET scan in which unpaired presentations of the tone conditioned stimulus and corneal airpuff unconditioned stimulus were administered, (ii) a paired training session to allow associative learning to occur, and (iii) a paired test session with PET scan. Brain regions exhibiting learning-related activation were identified as those areas that showed significant differences in glucose metabolism between the unpaired control condition and well-trained state in the 9 subjects who met the learning criterion. Areas showing significant activation included bilateral sites in the inferior cerebellar cortex/deep nuclei, anterior cerebellar vermis, contralateral cerebellar cortex and pontine tegmentum, ipsilateral inferior thalamus/red nucleus, ipsilateral hippocampal formation, ipsilateral lateral temporal cortex, and bilateral ventral striatum. Among all subjects, including those who did not meet the learning criterion, metabolic changes in ipsilateral cerebellar nuclei, bilateral cerebellar cortex, anterior vermis, contralateral pontine tegmentum, ipsilateral hippocampal formation, and bilateral striatum correlated with degree of learning. The localization to cerebellum and its associated brainstem circuitry is consistent with neurobiological studies in the rabbit model of eyeblink classical conditioning and neuropsychological studies in brain-damaged humans. In addition, these data support a role for the hippocampus in conditioning and suggest that the ventral striatum may also be involved.

Constructing a Neuroscientific Pastoral Theology of Fear and Hope

Contemporary therapeutic circles utilize the concept of anxiety to describe a variety of disorders. Emotional reductionism is a detriment to the therapeutic community and the persons seeking its help. This dissertation proposes that attention to the emotion of fear clarifies our categorization of particular disorders and challenges emotional reductionism. I propose that the emotion of fear, through its theological relationship to hope, is useful in therapeutic practice for persons who experience trauma and PTSD. I explore the differences between fear and anxiety by deconstructing anxiety. Through this process, I develop four categories which help the emotion of fear stand independent of anxiety in therapy. Temporality, behaviors, antidote and objects are categories which distinguish fear from anxiety. Together, they provide the impetus to explore the emotion of fear. Understanding the emotion of fear requires an examination of its neurophysiological embodiment. This includes the brain structures responsible for fear production, its defensive behaviors and the evolutionary retention of fear. Dual inheritance evolutionary theory posits that we evolved physically and culturally, helping us understand the inescapability of fear and the unique threats humans fear. The threats humans react to develop through subjective interpretations of experience. Sometimes threats, through their presence in our memories and imaginations, inhibit a person's ability to live out a preferred identity and experience hope. Understanding fear as embodied and subjective is important. Process theology provides a religious framework through which fear can be interpreted. In this framework, fear is developed as an adaptive human response. Moreover, fear is useful to the divine-human relationship, revealing an undercurrent of hope. In the context of the divine-human relationship fear is understood as an initial aim which protects a person from a threat, but also preserves them for novel future relationships. Utilizing a "double-listening" stance, a therapist hears the traumatic narrative and counternarratives of resistance and resilience. These counternarratives express an orientation towards hopeful futures wherein persons thrive through living out a preferred identity. A therapeutic practice incorporating the emotion of fear will utilize the themes of survival, coping and thriving to enable persons to place their traumatic narrative within their meaning systems.

Portfolio efficiency tests with conditioning information using empirical likelihood estimation

We evaluate the use of Generalized Empirical Likelihood (GEL) estimators in portfolios efficiency tests for asset pricing models in the presence of conditional information. Estimators from GEL family presents some optimal statistical properties, such as robustness to misspecification and better properties in finite samples. Unlike GMM, the bias for GEL estimators do not increase as more moment conditions are included, which is expected in conditional efficiency analysis. We found some evidences that estimators from GEL class really performs differently in small samples, where efficiency tests using GEL generate lower estimates compared to tests using the standard approach with GMM. With Monte Carlo experiments we see that GEL has better performance when distortions are present in data, especially under heavy tails and Gaussian shocks.

Kazakhstan's attitude towards integration with Russia: less love, more fear. OSW Commentary No. 137, 29.05.2014

Russia’s annexation of Crimea and destabilization of Ukraine have created a new context for Kazakhstan’s foreign and domestic policy. The ongoing crisis in the relations with Russia and the West has also changed the current order in the entire post-Soviet area. From Astana’s perspective, the Kremlin’s policy towards Ukraine can be considered dangerous since it shows Russia’s determination to interfere with the domestic affairs of its neighbours in the pursuit of its own interests. Furthermore, this policy reveals and raises the price a country needs to pay for its potential attempts to break free from the Russian zone of influence. At present the biggest challenge for the authorities in Astana is the accelerated implementation of the idea of the Eurasian Union promoted by Moscow, which is to be another stage in the integration of post-Soviet states (presently Russia, Kazakhstan and Belarus). The signing of the Eurasian Union’s founding documents planned for late May 2014 and the launch of this organisation (scheduled for January 2015) is sure to bring Kazakhstan closer to Russia and simultaneously limit its economic and political independence. Nevertheless, Astana’s position in relations with Moscow will to a large extent depend on the new shape of the relations between Russia and China. China is pursuing its own strategic interests in Central Asia (including in the energy sector) and its main partner in the region is Kazakhstan. At the domestic level, Russia’s actions in Ukraine made the authorities in Astana fear that measures similar to those used in Ukraine could be applied towards Kazakhstan. On the one hand this has led to increased efforts aimed at consolidating the state and strengthening its structures, and on the other hand it has brought about a revision of those aspects of domestic policy which Russia could interpret as a pretext for interfering.
