The Export Base Model with a Supply-Side Stimulus to the Export Sector

In the export-base model, the level of a region’s economic activity is underpinned by the performance of its export sector (Daly, 1940; Dixon and Thirlwall, 1975; Kaldor, 1970; North, 1955). This theory is now almost universally represented as a primitive version of the familiar Input-Output (IO) or Keynesian demand-driven approach, where regional output is linked to regional exports through a rather mechanistic multiplier process (Romanoff, 1974). Further, in a standard IO inter-regional framework, the expansion of output in one region always generates positive impacts on other regions. That is to say, there is always a positive spread, and no negative backwash, effect. However, these models typically embody no supply-side constraints. What is more, the stimulus to the export sector is often thought to come through supply-side improvements (North, 1955; McCombie, 1992). Whilst accepting that the development of a healthy export base is generally central to promoting the growth of the regional economy, the relationship is likely to be much more complex than is usually thought. Also whilst an increase in regional exports typically increases economic activity in the target region, the effect on other regions is less straightforward (Myrdal, 1957). In this paper we begin by using a single-region IO analysis of the operation of a stylised export base model. The impact of a conventional increase in export demand is compared to a situation in which increased competitiveness underpins the improved export performance. This analysis is then extended through the use of an inter-regional (Scotland–Rest of the UK) Computable General Equilibrium (CGE) model. In simulation, different exogenous demand and supply side disturbances are calibrated so as to generate the same long-run expansion in Scottish manufacturing exports. The subsequent specific evolutions of regional GDP and employment in both Scotland and the rest of the UK (RUK) are then tracked.Export base, efficiency improvement, regional growth

IL-4 Inhibits IL-1β-Induced Depressive-Like Behavior and Central Neurotransmitter Alterations

It has been known that activation of the central innate immune system or exposure to stress can disrupt balance of anti-/proinflammatory cytokines. The aim of the present study was to investigate the role of pro- and anti-inflammatory cytokines in the modulation of depressive-like behaviors, the hormonal and neurotransmitter systems in rats. We investigated whether centrally administered IL-1β is associated with activation of CNS inflammatory pathways and behavioral changes and whether treatment with IL-4 could modulate IL-1β-induced depressive-like behaviors and central neurotransmitter systems. Infusion of IL-4 significantly decreased IL-1β-induced anhedonic responses and increased social exploration and total activity. Treatment with IL-4 markedly blocked IL-1β-induced increase in PGE2 and CORT levels. Also, IL-4 reduced IL-1β-induced 5-HT levels by inhibiting tryptophan hydroxylase (TPH) mRNA and activating serotonin transporter (SERT) in the hippocampus, and levels of NE were increased by activating tyrosine hydroxylase (TH) mRNA expression. These results demonstrate that IL-4 may locally contribute to the regulation of noradrenergic and serotonergic neurotransmission and may inhibit IL-1β-induced behavioral and immunological changes. The present results suggest that IL-4 modulates IL-1β-induced depressive behavior by inhibiting IL-1β-induced central glial activation and neurotransmitter alterations. IL-4 reduced central and systemic mediatory inflammatory activation, as well as reversing the IL-1β-induced alterations in neurotransmitter levels. The present findings contribute a biochemical pathway regulated by IL-4 that may have therapeutic utility for treatment of IL-1β-induced depressive behavior and neuroinflammation which warrants further study

Korean Pre-service Teachers\u27 Perception of Parent-Teacher Partnership: The Effects of Motivation and Teaching Beliefs

This chapter examined early childhood pre-service teachers’ perceptions of the parent-teacher partnership, especially for the interaction effect between motivation and teaching beliefs on the parent-teacher partnership among Korean early childhood pre-service teachers. The participants for this study included 265 pre-service teachers in two different types of childhood teacher education programs (early childhood education and elementary education) in Seoul, Kyunggi, and Busan in Korea. The results from t-tests and ANOVA showed that pre-service teachers’ perceptions of the parent-teacher partnership were differentiated by student status in the teacher education program with discrete differences depending on subfactors. Constructivist teaching beliefs were the most significant variable to predict the pre-service teachers’ perceptions of the parent-teacher partnership. Even though there were no statistically meaningful interaction effects between intrinsic motivation and constructivist teaching beliefs, two-way interaction plots implied interaction effects between these two predictors. Based on the results, we discussed the implications of the results in regard to curriculum development and educational policy for future endeavors to enhance teacher education quality and educational effectiveness

Impaired Sacculocollic Reflex in Lateral Medullary Infarction

Objective: The aim of this study was to determine saccular dysfunction by measuring cervical vestibular-evoked myogenic potentials (cVEMP) and to correlate abnormality of cVEMP with results of other vestibular function tests in lateral medullary infarction (LMI). Methods: We recorded cVEMP in 21 patients with LMI documented on MRI. cVEMP was induced by a short tone burst and was recorded in contracting sternocleidomastoid muscle while patients turned their heads forcefully to the contralateral side against resistance. Patients also underwent video-oculographic recording of spontaneous, gaze-evoked and head shaking nystagmus (HSN), evaluation of ocular tilt reaction (OTR), measurement of the subjective visual vertical (SVV) tilt, bithermal caloric tests, and audiometry. Results: Nine patients (43%) showed abnormal cVEMP, unilateral in seven and bilateral in two. The cVEMP abnormalities included decreased p13–n23 amplitude in four, delayed p13/n23 responses in five, and both decreased and delayed responses in two. The abnormal cVEMP was ipsilesional in five, contralesional in two, and bilateral in two. The prevalence of OTR/SVV tilt, spontaneous nystagmus, and HSN did not differ between the patients with normal and abnormal cVEMP. Conclusion: cVEMP was abnormal in approximately half of the patients with LMI. The abnormal cVEMP indicates damage to the descending sacculocollic reflex pathway or disruption of commissural modulation between the vestibular nuclei

A homozygous Keap1-knockout human embryonic stem cell line generated using CRISPR/Cas9 mediates gene targeting

Kelch-like ECH-associated protein 1 (keap1) is a cysteine-rich protein that interacts with transcription factor Nrf2 in a redox-sensitive manner, leading to the degradation of Nrf2 (Kim et al., 2014a). Disruption of Keap1 results in the induction of Nrf2-related signaling pathways involving the expression of a set of anti-oxidant and anti-inflammatory genes. We generated biallelic mutants of the Keap1 gene using a CRISPR-Cas9 genome editing method in the H9 human embryonic stem cell (hESC). The Keap1 homozygous-knockout H9 cell line retained normal morphology, gene expression, and in vivo differentiation potential. (C) 2016 The Author(s). Published by Elsevier B.V.

Presented at the 12th International Conference on Human-Computer Interaction, Beijing, China, July 2007.The original publication is available at www.springerlink.comThe Gesture and Activity Recognition Toolit (GART) is a user interface toolkit designed to enable the development of gesture-based applications. GART provides an abstraction to machine learning algorithms suitable for modeling and recognizing different types of gestures. The toolkit also provides support for the data collection and the training process. In this paper, we present GART and its machine learning abstractions. Furthermore, we detail the components of the toolkit and present two example gesture recognition applications

Predicting the potential distribution in South Korea of two mealybug species (Hemiptera: Pseudococcidae) intercepted on pineapples in quarantine

Dysmicoccus brevipes (Cockerell) and Dysmicoccus neobrevipes Beardsley are major pests of pine­apples, ornamentals, and vegetable crops in many countries around the world. The potential distribution of these mealybug pests into South Korea remains a prime concern because of their high incidence in intercep­tions screened during inspection. Hence, these species prompted a modelling effort to assess their potential risk of introduction. Potential risk maps were developed for these pests with the CLIMEX model based on occurrence records under environmental data. The potential distribution of these pests in South Korea in the 2020s, 2050s and 2090s is projected based on the RCP 8.5 climate change scenario. Results show that D. brevipes and D. neobrevipes have little potential for invasion in the exterior environment of South Korea due to high cold stress. However, for D. brevipes, three locations in Jejudo were predicted to be marginally suit­able for this pest under future climate factors. In that respect, the results of these model predictions could be used to prepare a risk-based surveying program that improves the probability of detecting early D. brevipes and D. neobrevipes populations. The introduction of an exotic species to new geographical areas without their natural enemies has often been followed by large outbreaks in their population and subsequent economic damage to plants (CABI 2023a). Mealy­bugs (Hemiptera: Pseudococcidae) are plant feeders that have a more-or-less cryptic way of life because of their small size and limited mobility (Kondo and Watson 2022a). They are almost always found associated with plants, and are commonly intercepted on imported plant material (PIS 2023). As a result, they can easily be transported to other areas on the plants on which they live. A total of 114 species have been considered as pests in the world (Kondo and Watson 2022b). As of 2005, some 255 exotic scale insect species had become established in the USA; of these, 53 species were mealybugs (Miller et al. 2005). In South Korea, 91 exotic species have been documented from 1910 to 2019; of these, three species are mealybugs (RDA 2019). Numerous kinds of insect pests were intercepted during import inspections at South Korean ports of entry. Mealybugs comprised 16.3% of the 198,086 interceptions from 1996 to 2022 (PIS 2023), of which, Dysmicoccus brevipes (Cockerell) (22.9% of the mealybug interceptions) and Dysmicoccus neobrevipes Beardsley (54.3%) were intercepted most frequently (Table 1). The pink pineapple mealybug (PPM), D. brevipes, was described in 1893 from pineapples in Jamaica. Since then, it has become a major pest of pineapples, ornamental plants and vegetable crops in many other countries in the world where it has spread by the international trade of these goods (García Morales et al. 2016). The grey pineapple mealybug (GPM), D. neobrevipes, is probably native to the Australasian region and was first reported in 1959 from Hawaii. Over the last 60 years, this species has been found in 44 coun­tries on a wide variety of host plants (García Morales et al. 2016)
