Lamina I of the rat spinal cord contains neurons that project to various brain areas including thalamus, periaqueductal grey matter (PAG), lateral parabrachial area (LPb), caudal ventrolateral medulla and a region in dorsal medulla that includes the nucleus tractus solitarius and dorsal reticular nucleus. We have shown that spinothalamic lamina I neurons are infrequent in rat lumbar enlargement, where they constitute ∼ 5% of the estimated 400 projection neurons on each side of the L4 segment (Al-Khater and Todd, 2009). They are more numerous in cervical enlargement, but the total number of lamina I projection neurons in this region was not known. Here we have used paired injections of retrograde tracers into the brainstem to estimate the number of lamina I projection cells in the C7 segment. Our results suggest that there are ∼ 215 lamina I projection cells per side, and that spinothalamic cells therefore make up ∼ 42% of this population. The proportion of lamina I projection neurons labelled from PAG is higher in cervical than lumbar enlargement, while the proportion labelled from dorsal medulla is similar in the two regions. We also found that lamina I cells in L4 that project to the dorsal medulla are included in the population retrogradely labelled from LPb, thus confirming the estimate that there are around 400 lamina I projection cells in this segment.
The reality of trade is that it takes two or more parties to do business, and therefore the capabilities of both selling and buying firms are important. Where over 60% of Small and Medium Enterprises (SMEs) in the USA and Canada have adopted some form of business process through a computer mediated network, such as the Internet, other countries have significantly lower adoption rates. In Asia and Latin America, where as many as 99% of all firms are classified as SMEs, low adoption rates may be an impediment to increased international trade. This paper takes a critical look at the existing research on adoption of e-business technology by SMEs internationally. In particular, we identify the gap in our knowledge about what makes SMEs in different countries capable of using the technology in their domestic and international supply chains. We present a typology of the business processes networked over computer-mediated processes from our preliminary empirical field research, interviewing 40 SMEs in Canada, Japan, China and Mexico. This is used to propose a model of international SME capability to guide future empirical research. The e-business capability of small and medium 225 234 D. A. Johnston and L.

The present study uses a two-phase mixed-methods design to explore the role of motivation to acculturate within the international student experience. Hierarchical regression analyses were conducted to test acculturation motivation (AM) as a predictor of international student adjustment and permanent residency intentions, over and above age, gender, academic year, and English competence. Greater motivation to acculturate was indeed a significant predictor of international student adjustment and increased intentions of pursuing permanent host country residency. To better understand how international students' experiences relate to levels of AM, qualitative analyses were employed. International students with low levels of AM were more likely to express negative feelings about cross-cultural adjustment, university perception, and peer relationships, compared to students with high levels of AM. Despite such differences, academic and developmental struggles as well as academic successes were similarly voiced across both comparison groups.
This qualitative study investigated the decision-making processes underlying international students’ motivation to study abroad and whether they were related to features of Arnett’s definition of emerging adulthood. A total of 64 international undergraduate students (21 men and 43 women) from 26 countries and in different years of study were interviewed while attending a large, ethnically diverse Canadian university. Using thematic analyses, eight underlying themes of motivations were identified, namely, new experiences, education, improved future career and immigration prospects, qualities of the host country, qualities of the institution, financial reasons, location, and friends and relatives in the host country. Many motivational factors to study abroad highlighted and expanded upon characteristics of Arnett’s theory of emerging adulthood, whereas others were unique to international students. Practical implications include providing universities with information that developmentally situates international students, enhancing universities’ ability to assist students to attain their goals for studying abroad.
