Price discovery for Chinese shares cross-listed in multiple markets

In this article we study the relationship between security returns cross-listed on the A share market of China and the H share market at the Stock Exchange of Hong Kong (SEHK). Most of these securities are also cross-listed on other markets. An important feature of this article is that we focus on the multilateral relationships between all cross-listed markets rather than concentrating only on the bi-lateral relationship between A and Hong Kong H shares. Using the impulse response functions and the variance decompositions from a Vector Autoregressive (VAR) process we show that the returns to the A share market are almost exclusively determined by domestic factors. In contrast, we find that the H share market is influenced by both the A share market within China and foreign stock markets elsewhere in the world. Impulse response functions suggest that innovations to the A share market and the Hong Kong H share market are partly transmitted to each other and to stock markets outside China. We show that liquidity has an important role to play in determining the impact that the home market has on cross-listed variance decompositions. © 2012 Copyright Taylor and Francis Group, LLC.

Proving My Competency One Test at a Time: Internationally Educated Nurses and the Canadian English Language Benchmark Assessment for Nurses

Abstract Professional language assessment is a new concept that has great potential to benefit Internationally Educated Professionals and the communities they serve. This thesis reports on a qualitative study that examined the responses of 16 Canadian English Language Benchmark Assessment for Nurses (CELBAN) test-takers on the topic of their perceptions of the CELBAN test-taking experience in Ontario in the winter of 2015. An Ontario organization involved in registering participants distributed an e-mail through their listserv. Thematic analyses of focus group and interview transcripts identified 7 themes from the data. These themes were used to inform conclusions to the following questions: (1) How do IENs characterize their assessment experience? (2) How do IENs describe the testing constructs measured by the CELBAN? (3) What, if any, potential sources of construct irrelevant variance (CIV) do the test-takers describe based on their assessment experience? (4) Do IENs feel that the CELBAN tasks provide a good reflection of the types of communicative tasks required of a nurse? Overall, participants reported positive experiences with the CELBAN as an assessment of their language skills, and noted some instances in which they felt some factors external to the assessment impacted their demonstration of their knowledge and skill. Lastly, some test-takers noted the challenge of completing the CELBAN where the types of communicative nursing tasks included in the assessment differed from nursing tasks typical of an IENs country or origin. The findings are discussed in relation to literature on high-stakes large-scale assessment and IEPs, and a set of recommendations are offered to future CELBAN administration. These recommendations include (1) the provision of a webpage listing all licensure requirements (2) monitoring of CELBAN location and dates in relation to the wider certification timeline for applicants (3) The provision of additional CELBAN preparatory materials (4) Minor changes to the CELBAN administrative protocols. Given that the CELBAN is a relatively new assessment format and its widespread use for high-stakes decisions (a component of nursing certification and licensure), research validating IEN-test-taker responses to construct representation and construct irrelevant variance is critical to our understanding of the role of competency testing for IENs.

Nanotechnology in food industry II: risk assessment and legislation

Currently, there is increasing use of nanomaterials in the food industry thanks to the many advantages offered and make the products that contain them more competitive in the market. Their physicochemical properties often differ from those of bulk materials, which require specialized risk assessment. This should cover the risks to the health of workers and consumers as well as possible environmental risks. The risk assessment methods must go updating due to more widespread use of nanomaterials, especially now that are making their way down to consumer products. Today there is no specific legislation for nanomaterials, but there are several european dispositions and regulations that include them. This review gives an overview of the risk assessment and the existing current legislation regarding the use of nanotechnology in the food industry.

Thyroid function in multidrug-resistant tuberculosis patients with or without human immunodeficiency virus (HIV) infection before commencement of MDR-TB drug regimen.

Background: Mycobacterium tuberculosis and human immunodeficiency virus (HIV) are known to cause abnormal thyroid function. There is little information on whether HIV infection aggravates alteration of thyroid function in patients with MDRTB. Objectives: This study was carried out to determine if HIV co-infection alters serum levels of thyroid hormones (T3, T4) and thyroid stimulating hormone (TSH) in patients with MDR-TB patients and to find out the frequency of subclinical thyroid dysfunction before the commencement of MDR-TB therapy. Methods: This observational and cross-sectional study involved all the newly admitted patients in MDR-TB Referral Centre, University College Hospital, Ibadan, Nigeria between July 2010 and December 2014. Serum levels of thyroid stimulating hormone (TSH), free thyroxine (fT4) and free triiodothyronine (fT3) were determined using ELISA. Results: Enrolled were 115 patients with MDR-TB, out of which 22 (19.13%) had MDR-TB/HIV co-infection. Sick euthyroid syndrome (SES), subclinical hypothyroidism and subclinical hyperthyroidism were observed in 5 (4.35%), 9 (7.83%) and 2 (1.74%) patients respectively. The median level of TSH was insignificantly higher while the median levels of T3 and T4 were insignificantly lower in patients with MDR-TB/HIV co-infection compared with patients with MDRT-TB only. Conclusion: It could be concluded from this study that patients with MDR-TB/HIV co-infection have a similar thyroid function as patients having MDR-TB without HIV infection before commencement of MDR-TB drug regimen. Also, there is a possibility of subclinical thyroid dysfunction in patients with MDR-TB/HIV co-infection even, before the commencement of MDR-TB therapy.

Actividad física e imagen corporal: conceptos y enfoques desde la equidad-inequidad en salud

Este trabajo rastrea el tratamiento dado a las categorías Actividad Física e Imagen Corporal en una selección de textos científicos del área de la salud; revisa la relación entre categorías y examina si en dichos textos son abordadas desde el enfoque de los Determinantes Sociales de la Salud o desde el enfoque de la Determinación Social de la Salud, usando la categoría de equidad como parámetro y explorando las implicaciones de ello. Su paradigma epistemológico es la construcción social del conocimiento y el eje metodológico el análisis de contenido. Los resultados muestran una construcción insipiente de las categorías, una relación diversa entre ellas y un privilegio del enfoque de los determinantes sociales de la salud en los textos académicos. Finalmente, el trabajo indaga sobre las implicaciones prácticas mediante un análisis de contenido de dos documentos de la OMS. Se concluye que en la práctica sí se reflejan las diferencias de enfoque.

La precaución jurídica en el tratamiento de la información periodística

Hoy se hace imperioso que la ética periodística se complemente con el tratamiento jurídico de la libertad de expresión. La precaución jurídica es la invitación a una visión integral de la ética profesional basada en la autorregulación y en el conocimiento de la teleología del periodismo
