Proposed U.S.-South Korea Free Trade Agreement and Potential Employment Effects: Analysis of Studies

[Excerpt] Similar to other trade agreements, the proposed U.S.-South Korea Free Trade Agreement(KORUS-FTA) has attracted both supporters and detractors, primarily over the impact the agreement could have on employment in the economy. Supporters argue that the agreement could create as many as 280,000 jobs in the economy. Others, however, argue that the agreement could lead to an overall loss of up to 159,000 jobs in various sectors of the economy. Still others contend that the United States stands to lose exports, employment, and extended economic opportunities if it fails to sign a trade agreement, while the European Union and other nations are lining up to finalize similar agreements with South Korea. Estimating the economic impact of trade agreements, however, is a daunting task, due to a lack of data and important theoretical and practical matters associated with generating results from economic models. In addition, such estimates provide an incomplete accounting of the total economic effects of trade agreements. This report assesses the results of a number of models that are being used to generate estimates of the effect of the KORUS FTA on employment. These studies were chosen specifically because they estimate (or can be used to estimate) data on employment effects of the trade agreement. All economic models incorporate various assumptions that are necessary in order for the model to generate results. Invariably, these approaches determine, to some extent, the results that are generated and, therefore, limit their representation of the real world economy. Currently, the various models produce widely disparate estimates of the number of jobs affected by the trade agreement, reflecting the various assumptions that are used in the models and differences in the approaches

Collaborative Leadership Learning; Developing Facilitation Skills for Collaborative Learning in Leadership Learning Groups.

many organisations working for example, with less hierarchical structures, with cross- organisational partners, or in professional environments. Leadership at all levels must be supported by leaders in top executive positions who develop their own capabilities both as leaders and in their role of leading the learning of leadership throughout their organisations. Their ideas of their role in leading learning will be shaped by their own leadership development experiences. Collaborative learning for leadership may be a model of learning that reflects the new leadership required; it may enable leaders to develop their own leadership capability in such a way that they feel enabled to work with others on their leadership development

Rural investment to accelerate growth and poverty reduction in Kenya:

"Kenya's economy is relatively diverse, with both agricultural and industrial potential. However, the economy has performed poorly over the last decade, and poverty and inequality have risen. This paper examines the impact of alternative growth paths and rural investments on poverty using an economy-wide model. It finds that if Kenya continues along its current growth path, its economy will have to grow by more than 10 percent per year over the coming decade to meet the Millennium Development Goal (MDG) of halving poverty by 2015. Therefore, Kenya must search for alternative sources of poverty-reducing growth. The results of the model indicate that poverty is unlikely to decline significantly without an acceleration of agricultural growth. Growth in agriculture is found to benefit both urban and rural households, whereas industry-led growth benefits a smaller segment of the urban population, thus exacerbating inequality. Kenya's current Economic Recovery Strategy, however, is not optimistic about agriculture's growth potential, focusing more heavily on industry-led growth. Therefore, as Kenya prepares its new national strategy, the country should place greater emphasis on and direct resources toward accelerating agricultural growth. In assessing the impact of rural investments on growth and poverty, the paper finds that increasing agricultural spending to meet the 10 percent target set by the Maputo Declaration would lift an additional 1.5 million people above the poverty line by 2015. Specific agricultural investments have higher returns in different parts of the country, however. Irrigation favors the lowlands and the poorest segment of the population, while research and extension (R&E) favors the midlands and highlands. Investment in R&E is also found to have the highest returns in both growth and poverty reduction. However, increasing agricultural spending to 10 percent of total spending is insufficient to meet either the MDG or the 6 percent agricultural growth target of the Comprehensive African Agriculture Development Program, which Kenya has recently adopted. . Achieving this target requires nonagricultural investments, such as in roads and market development. Building rural roads and reducing agricultural transaction costs significantly reduces poverty and encourages growth beyond rural areas. While it is necessary to increase spending on agriculture, the fiscal burden of an agricultural strategy can be greatly reduced by improving investment efficiency." from Author's AbstractAgriculture, Rural investment, Public investment, Poverty reduction, Inequality, Pro-poor growth,

The role of gesture delay in coda /r/ weakening: an articulatory, auditory and acoustic study

The cross-linguistic tendency of coda consonants to weaken, vocalize, or be deleted is shown to have a phonetic basis, resulting from gesture reduction, or variation in gesture timing. This study investigates the effects of the timing of the anterior tongue gesture for coda /r/ on acoustics and perceived strength of rhoticity, making use of two sociolects of Central Scotland (working- and middle-class) where coda /r/ is weakening and strengthening, respectively. Previous articulatory analysis revealed a strong tendency for these sociolects to use different coda /r/ tongue configurations—working- and middle-class speakers tend to use tip/front raised and bunched variants, respectively; however, this finding does not explain working-class /r/ weakening. A correlational analysis in the current study showed a robust relationship between anterior lingual gesture timing, F3, and percept of rhoticity. A linear mixed effects regression analysis showed that both speaker social class and linguistic factors (word structure and the checked/unchecked status of the prerhotic vowel) had significant effects on tongue gesture timing and formant values. This study provides further evidence that gesture delay can be a phonetic mechanism for coda rhotic weakening and apparent loss, but social class emerges as the dominant factor driving lingual gesture timing variation

An effective palynological preparation procedure using hydrogen peroxide

Most pre-Quaternary palynology samples are currently prepared by demineralization of the sediment/sedimentary rock matrix using hydrochloric and hydrofluoric acids (HCl and HF respectively). If a consistently effective alternative to this procedure can be developed, palynological processing will be made significantly less hazardous to both laboratory personnel, and to the wider environment. Furthermore, most non-acid processing methods are normally quicker and cheaper than matrix dissolution using acid. Some authors have previously used hydrogen peroxide (H2O2) to extract palynomorphs by the physico–chemical disaggregation of the clay fraction. However, H2O2 is a powerful oxidizing agent and hence can potentially destroy sedimentary organic material, including palynomorphs. A new method using hot H2O2, where exposure of the sample material to the H2O2 is minimized, has been developed. Crushed sample material in a suitable vessel is placed on a hot plate for one minute, treated with 15–30% H2O2 for 10 minutes, then the residue is diluted with cold distilled water. Disaggregated sample material tends to float, and is decanted into a large vessel containing distilled water to further dilute the H2O2. If any undisaggregated sample remains, the procedure is repeated several times if necessary. Relatively indurated sedimentary lithotypes normally require several treatments. The reason for this stepwise treatment is that the organic material is not exposed to H2O2 for sustained periods, thereby reducing the possibility of palynomorph damage/degradation due to oxidation. When the sample matrix has been fully disaggregated, the residue can be further processed as appropriate. In this study, eight samples of Carboniferous, Jurassic, Paleogene, and Quaternary age were prepared quantitatively using the new H2O2 method. These were all prepared using 30% H2O2. For comparison, they were also prepared quantitatively using HCl/HF and/or sodium hexametaphosphate [(NaPO3)6]. Quantitative preparations allow the concentration of palynomorphs extracted to be determined, and therefore the effectiveness of the techniques used can be compared objectively. The palynomorph residues derived from these three techniques varied markedly. The H2O2 method does not consistently disaggregate all the sample material, particularly the older and more indurated lithotypes. Some evidence of oxidation effects was observed. Two samples of Mississippian mudstone from the U.S.A. were prepared using H2O2 and (NaPO3)6. Both methods produced abundant miospores, however the H2O2 procedure yielded far higher palynomorph concentrations than the (NaPO3)6 technique. Minor degradation of palynomorphs in the H2O2 preparation was noted. The H2O2 and HCl/HF methods were compared directly on a palynomorph-rich sample of Upper Carboniferous mudstone from offshore Scotland. Both preparations produced abundant miospores. The HCl/HF method had significantly higher recovery levels than the H2O2 procedure. It appears that the H2O2 method simultaneously macerates the matrix, and oxidizes any amorphous organic material (AOM) present. In this sample, the HCl/HF residue was relatively rich in AOM. By contrast, the H2O2 preparation is virtually clear of this phytoclast type, which partially obscures palynomorphs. Two samples of the Middle Jurassic Grantham Formation of eastern England were processed using H2O2 and HCl/HF. The two methods produced abundant palynofloras of similar palynomorph concentrations. Two dinoflagellate cyst acmes within the Danian (Paleogene) part of the López de Bertodano Formation of Seymour Island, Antarctica were also tested using H2O2, (NaPO3)6, and HCl/HF. TheH2O2 preparation completely destroyed the dominant taxon, Palaeoperidinium pyrophorum, in one sample. By contrast, the (NaPO3)6 and HCl/HF preparations produced abundant, fully representative palynofloras. In the other sample, the acme of Spinidinium spp. is completely unaffected by the H2O2 preparation procedure. The final sample of this study is an unconsolidated clay of Late Pleistocene age from offshore Scotland. Both the H2O2 and HCl/HF preparations proved similar in both taxonomic content and overall palynomorph yield. The new method of preparation using hot H2O2 has proved to be extremely effective. In particular, it appears to be superior to the (NaPO3)6 procedure for indurated lithotypes. However care should be taken because H2O2 can destroy certain dinoflagellate cysts and kerogen macerals which are especially susceptible to oxidation. Further development work, and more comparative testing of the H2O2, (NaPO3)6, and HCl/HF procedures, should be undertaken

Aligned cellular and acellular collagen guidance substrates for peripheral nerve repair

There is a clinical demand to shorten the delay of reinnervation and improve functional recovery after peripheral nerve injury. A peripheral nerve repair device with the ability to direct and promote axon growth across a lesion would be a promising alternative to nerve autograft repair, the current gold standard treatment. The growth of axons across a lesion is most effective when supported by columns of aligned Schwann cells, as found in an autograft. Here we report the development of a robust aligned cellular collagen biomaterial that supports and directs neuronal growth. We also investigate the potential of these aligned cells to precondition the collagen biomaterial, before they are freeze-killed, leaving an acellular guidance matrix
