Gap junctions are ubiquitous plasma membrane specializations that allow cells to exchange small molecules and ions directly. The isolation, biochemical characterization and molecular cloning of the major protein of rat liver gap junctions lead to a clearer view of these membrane zones that allow cells to ‘talk’ to each other and co‐ordinate their activities in tissues and organs.

Gap junction intercellular communication channels permit the exchange of small regulatory molecules and ions between neighbouring cells and coordinate cellular activity in diverse tissue and organ systems. These channels have short half‐lives and complex assembly and degradation pathways. Much of the recent work elucidating gap junction biogenesis has featured the use of connexins (Cx), the constituent proteins of gap junctions, tagged with reporter proteins such as Green Fluorescent Protein (GFP) and has illuminated the dynamics of channel assembly in live cells (...) by high‐resolution time‐lapse microscopy. With some studies, however, there are potential short‐comings associated with the GFP chimeric protein technologies. A recent report by Gaietta et al., has highlighted the use of recombinant proteins with tetracysteine tags attached to the carboxyl terminus of Cx43, which differentially labels ‘old’ and ‘new’ connexins thus opening up new avenues for studying temporal and spatial localisation of proteins and in situ trafficking events.1 BioEssays 24:876–880, 2002. © 2002 Wiley Periodicals, Inc.

We discuss our surgical philosophy concerning the subtle interplay between the size of the surgical margin taken and the resultant morbidity from ablative oncological. procedures, which is ever more evident in the treatment of head and neck malignancy. The extent of tissue resection is determined by the "trade off" between cancer control and the perioperative, functional and aesthetic morbidity and mortality of the surgery. We also discuss our dilemmas concerning recent minimally invasive endoscopic microsurgical. techniques for the trans-oral laser removal. (...) or co-ablation of aero-digestive tract tumours, which result in a minimal. surgical margin of oncological clearance. By a process of inductive argument as to the nature of the surgical margin, we consider whether the risks of taking a lesser margin with adjuvant therapy is justified by the attendant gain in reduced surgical morbidity and the possible costs in tumour control.

The practice of “lectio divina”–-devotional reading of the biblical text–-is popular these days. While people have explored this practice within Roman Catholic history, little research has been conducted regarding the character of devotional Bible-reading within evangelical traditions and its relationship to what is currently identified as lectio divina. The present article seeks to offer some reflections regarding the practice of devotional Bible-reading in evangelical Christianity and to do so using the categories commonly employed to describe lectio divina. First, it will (...) demonstrate how the devotional reading of Scripture has been regarded as a recognized spiritual practice in the history of evangelical Christianity, a practice that was expected to be employed in association with certain attitudes and assumptions. Next, the article examines the each of the elements of classical lectio divina–-reading, meditation, prayer, contemplation, and action. Finally, the article concludes by offering a few suggestions regarding more recent developments in evangelicalism and on the use of the practice of devotional Bible reading today. (shrink)

This article is intended to serve as a reminder of the themes that have been present in Christian spiritual formation through the centuries. In a WISDOM orientation we ground our approach to CSF in Scripture, in theology, and in “best practices,” yet we also seek to thoughtfully locate CSF within specific contexts. The WISDOM acronym reminds us that formation must involve: Wise planning, where the leaders prayerfully seek to implement what is needed in a specific situation; Intentionality, calling people to (...) commit to walk differently from the ways of the world; Scripture, salvation, and Spirit, where the Salvation message and the Spirit-led mission of the whole of Scripture provides the framework for CSF; Discipleship, where the end of CSF is the imitation of Jesus Christ; Optimism, where we pursue our formation in an atmosphere of hope and expectation of change; and Means.

A new journal invites reflection on the nature and purpose for such a publication. This article exegetes the ‘call for papers’ of the Journal of Spiritual Formation & Soul Care in order to cast a vision for the journal. In treating the subject matter of the journal, definitions are proposed of ‘Christian spirituality,’ ‘spiritual formation,’ ‘transformation in Christ,’ and ‘soul care.’ Next, an argument for an explicitly evangelical spirituality is presented. The interdisciplinary methodology of the journal is highlighted as well (...) as the overall aim of the journal. As it turns out fleshing out the nature and purpose of this journal is part and parcel with fleshing out what it means to develop evangelical scholarship on Christian spirituality. (shrink)

While many Christians are finding comfort in forms of prayer that emphasize silence, others find concern with just such forms, seeing them as doctrinally unfaithful innovations of early monks. This article, then, investigates one influential early monk, Evagrius of Pontus, regarding thoughtless prayer. The article summarizes Evagrius’ life and monastic practice. It explores Evagrius’ mystical theology in general and particularly his understanding of the roles that prayer plays in the various stages of development in Christian maturity. The article then develops (...) a biblical and evangelical response to Evagrius’ approach, examining themes of the transcendent greatness of God, silence, and prayer in the Scriptures. Based on these investigations, the article offers three practical suggestions concerning the use of thoughtless prayer for Christians today. (shrink)

This reader has been assembled in response to increasing dissatisfaction among a growing number of international relations scholars with the currently dominant theory of realism as well as in recognition of the large number of newly independent states which are having to write new constitutions and develop foreign relations. The book includes excerpts and essays from political theory and international relations which provide a starting point for further study of these subjects. It draws together writings representing two distinct traditions and (...) demonstrates their interconnections. In political theory, excerpts are drawn from classical texts which have an important bearing on problems of international relations. In international relations, the collection includes essays which have had a seminal influence on the development of this discipline. (shrink)

The present study applies a new method for investigating dynamic unconscious processes. The method consists of selection of words from patient interview and test protocols that in the clinicians' judgments capture the patients' conscious symptom experience and the hypothetical unconscious conflict related to the symptom, subliminal and supraliminal presentation of these words, signal analysis of event-related potentials obtained to the word presentations. Eight phobics and three patients suffering from pathological grief reactions served as subjects. A time-frequency ERP analysis revealed that (...) subjects' ERPs classified the unconscious conflict words better subliminally than supraliminally, while the reverse was true for the conscious symptom words = 2.82, p = .011). The relationship between frequency and latency revealed a similar mirror image pattern for the unconscious conflict and conscious symptom words . This method demonstrated that objective, brain-based evidence for unconscious conflict can be obtained. (shrink)

This paper theorizes that the effect of human rights violations on US economic aid is conditioned by the salience of US national security concerns. National security concerns will be more salient in situations where recipients contribute to maintaining US security and in temporal eras when the USA is perceived as being under increased external threat. As the relational and temporal salience of national security increases, any negative effect of human rights violations on US economic aid should decrease. I test this (...) hypothesis by examining US economic aid allocations to states from 1977 to 2005. The results show that the salience of national security concerns present in the US-recipient relationship does condition the relationship between human rights violations and US economic aid. There are also significant differences between different temporal eras of US foreign aid allocation. Future work should address how conflicts between interests and values in US foreign policy are negotiated. (shrink)

Several issues are raised concerning the notion that a single strategy explains Fitts' law and the linear speed/accuracy trade-off. Two additional concerns are discussed: (1) distance is programmed, (2) the fact that movements produced without the aid of vision obey Fitts' law does not mean that sighted movements must be explained without regard to vision.

Our approach is based on a tri-partite method of integrating psychodynamic hypotheses, cognitive subliminal processes, and psychophysiological alpha power measures. We present ten social phobic subjects with three individually selected groups of words representing unconscious conflict, conscious symptom experience, and Osgood Semantic negative valence words used as a control word group. The unconscious conflict and conscious symptom words, presented subliminally and supraliminally, act as primes preceding the conscious symptom and control words presented as supraliminal targets. With alpha power as a (...) marker of inhibitory brain activity, we show that unconscious conflict primes, only when presented subliminally, have a unique inhibitory effect on conscious symptom targets. This effect is absent when the unconscious conflict primes are presented supraliminally, or when the target is the control words. Unconscious conflict prime effects were found to correlate with a measure of repressiveness in a similar previous study (Shevrin et al., 1992, 1996). Conscious symptom primes have no inhibitory effect when presented subliminally. Inhibitory effects with conscious symptom primes are present, but only when the primes are supraliminal, and they did not correlate with repressiveness in a previous study (Shevrin et al., 1992, 1996). We conclude that while the inhibition following supraliminal conscious symptom primes is due to conscious threat bias, the inhibition following subliminal unconscious conflict primes provides a neurological blueprint for dynamic repression: it is only activated subliminally by an individual's unconscious conflict and has an inhibitory effect specific only to the conscious symptom. These novel findings constitute neuroscientific evidence for the psychoanalytic concepts of unconscious conflict and repression, while extending neuroscience theory and methods into the realm of personal, psychological meaning.

President Trump verbally attacked human rights in his campaign rhetoric in 2016, leading many to believe that he would undermine the role of human rights in US foreign policy as President. I examine whether or not President Trump’s anti-human rights rhetoric manifested in US foreign policy by analyzing potential changes in how human rights were considered in foreign aid allocations under the Trump Administration. While President Trump had a number of executive tools at his disposal to exert control over foreign (...) aid allocation, he would still have had to overcome considerable bureaucratic and legislative inertia in order to implement his anti-human rights agenda in US foreign aid. I demonstrate that he was unsuccessful in overcoming this inertia, at least in the first 2 years of his Administration (the years for which data is currently available). If anything, human rights received more consideration under President Trump than under President Obama. (shrink)

Higher education has expanded at astonishing rates around the world. We seek to understand the oppositions that periodically arise, which may produce enrollment declines and/or imposition of political controls. The post-1945 growth of higher education was – to a greater extent than is often recognized – propelled by the liberal, and later neoliberal, international order. Oppositions arise from illiberal alternatives, which also may organize globally. The recent weakening of the global liberal order, associated with growing populism and nationalism, creates conditions (...) for a new wave of oppositions. We hypothesize that attacks on higher education emerge in countries less integrated into world society and in countries linked to international structures that support illiberal alternatives. We examine cross-national data on higher education over the period 1960–2017. Enrollments and funding are higher in societies more tightly linked to world society and lower in countries tied to illiberal international organizations. Analyses of enrollments in various fields, constraints on academic freedom, and terrorist attacks on education institutions show similar pattern. Finally, we observe heterogeneity in the forms of illiberal opposition: countries that suppress academic freedom generally are less likely to restrict enrollments. (shrink)
