The aim of this paper is to characterize the bilateral trade between Mexico and the United States during the period 1981-2017, highlighting the effects of Mexico's accession to the GATT and the entry into force of NAFTA, as well as the entry of China into the WTO. Although there have been decelerations at some point, results show an increase in trade volume and, consequently, in the intensity of bilateral trade, but in the latter case with some falls resulting from the different growth rates of world trade. Intra-industrial trade, meanwhile, recorded sustained growth, which could reflect a greater vertical integration of production processes. Keywords: trade volume, trade intensity, intra-industrial trade, Grubel and Lloyd index added and corrected, economic integration.

In the course of the last 2 years economic performance in the major 7 economies has become less synchronised. In 1988 GNP grew by more than 3.5 per cent in all seven economies, with growth rates either at or close to cyclical highs. However for 1991 we expect negative GNP growth for Canada and the United Kingdom, negligible growth in the United States, growth of around 1.5 per cent in France and Italy, and of over 3 per cent in Germany and Japan. Table 1 shows that GNP growth in the major 7 economies is expected to slow to 1.2 per cent in 1991. Chart 1 highlights the different responses among the major 4 economies.

Exchange Rate Fluctuations

This article examines one feature of the pre—Federal Reserve financial system that has not been widely researched: the market for bank drafts (the “domestic exchanges”). Though the exchanges existed for nearly a century, critics argued that exchange rate fluctuations exacerbated financial panics. We find, using cointegration analysis over the period from 1899 to 1908, that differences in growth rates across regions caused predictable movements in rates. We conclude that the exchanges promoted efficiency in the payments system. This supports the view that the private sector might have developed a unified national system had the Fed not abolished the exchanges.

Cold Hardy

Hydrangea arborescens L., or smooth hydrangea, is a shrub native to the eastern United States that produces large corymbs of pure white flowers in early summer. Rated as hardy to USDA cold hardiness zone 4, it is one of the most cold-hardy members of the genus. Hydrangea involucrata Sieb. is an Asian species that produces lavender-blue flowers in midsummer. This species, which is not widely cultivated in the United States, is only rated as hardy to zone 6 to 7. The objective of this study was to hybridize H. arborescens and H. involucrata for the purpose of combining cold hardiness and flower color. Reciprocal crosses were made between H. involucrata and H. arborescens during Summer 2003. No seed were obtained when H. involucrata was used as the maternal parent. Approximately 500 seeds were collected from H. arborescen × H. involucrata hybridizations, 36 of which germinated. Several of these seedlings were extremely weak and died at a young age. The remaining eight plants have not flowered and all possess reduced growth rates. Hybridity was verified using RAPD markers and morphological comparisons of hybrids and parents.

Background: COVID-19 pandemic mitigation requires evidence-based strategies. Because COVID-19 can spread via respired droplets, most US states mandated mask use in public settings. Randomized control trials have not clearly demonstrated mask efficacy against respiratory viruses, and observational studies conflict on whether mask use predicts lower infection rates. We hypothesized that statewide mask mandates and mask use were associated with lower COVID-19 case growth rates in the United States. Methods: We calculated total COVID-19 case growth and mask use for the continental United States with data from the Centers for Disease Control and Prevention and Institute for Health Metrics and Evaluation. We estimated post-mask mandate case growth in non-mandate states using median issuance dates of neighboring states with mandates. Results: Earlier mask mandates were not associated with lower total cases or lower maximum growth rates. Earlier mandates were weakly associated with lower minimum COVID-19 growth rates. Mask use predicted lower minimum but not lower maximum growth rates. Growth rates and total growth were comparable between US states in the first and last mask use quintiles during the Fall-Winter wave. These observations persisted for both natural logarithmic and fold growth models and when adjusting for differences in US state population density. Conclusions: We did not observe association between mask mandates or use and reduced COVID-19 spread in US states. COVID-19 mitigation requires further research and use of existing efficacious strategies, most notably vaccination.

Empowering Settings

In an education system marred by inequity, urban schools in the United States are faced with the challenge of helping students from marginalized groups succeed. While many strategies have been tried, most are built on deficit-based models that blame students and teachers for a lack of achievement and ignore the role of power within the school setting. Building on the body of research on school climate, critical pedagogy, and empowering settings, the present study developed a model of student empowerment using a case study of an ethnically diverse urban high school in the midwestern United States. Participant observation, focus groups, and interviews were utilized to identify classroom and school characteristics related to student empowerment. Students reported equitable teacher–student relationships, integrated student leadership, and shared decision making. Similarly, school staff reported high staff empowerment and sense of community. The Student Empowerment Model is a useful framework for school improvement, adding “power” to the broader literature on school climate and extending the work on empowering settings to schools.

Polarised Growth within a Multi-Growth-Centre Environment: A Case Study of the United States 1920–1970

Growth Diffusion

The existence of polarised growth is an indication that growth centres do in fact exist. This paper describes a method to test for polarised growth within a multi-growth-centre environment. Application of the method in the United States shows that there are centres around which growth is polarised. However, this polarisation is not as straightforward as expected and it is shown that the type of polarisation can vary with time and with the size of centres to which growth is diffused. For example, in recent decades small centres were positively polarised around growth centres whereas large centres were negatively polarised. The latter result is an indication that the use of growth centres may not always be a good regional planning tool. By analysis of the polarisation of growth rates in a system of centres, information is also given on the mechanism of growth diffusion.

The almond is native to Iran and surrounding countries as well as Asia. In 2017, world production of almonds was 2.2 million tones, with the United States providing 46% of the total. According to FAO Afghanistan is one of the 10 top producers of almonds. The study examined the growth and instability of area, production, export and consumption of almond in Afghanistan from 2000 to 2017. Exponential function fitted to estimate compound annual growth rates (CAGR) in area, production, export and consumption of almond, and Cuddy – Della Valle indices are used in the study. The compound growth rates for area, production and productivity of almonds in Afghanistan were 5.77 %, 7.37 % and 1.52 % respectively. Area under almond crop exhibited medium (19,52) instability, where production and productivity shown high (50.05 and 49.01) instability respectively, during this period. Almond consumption grew by 6.75 per cent and export grew with compound annual growth rate of 6.12 per cent from the year 2000 to 2017.Both export and consumption of almond registered high instability in this period.
