Finland: An Exemplary STEM Educational System

There is a need for an increase in the number of students entering fields of science, technology, engineering, and mathematics (STEM) and the only way for that to happen is for educational reforms to be put into place (PCAST, 2012). Improvement and focus on STEM education are a concern of all nations whether they have an emerging economy or one that is long established. The world of the 21st century is such that in order to compete globally countries must invest in STEM education (Kennedy & Odell, 2014). The United States scores on the Program for International Student Assessment (PISA) were not in the top ten for reading, mathematics, nor science. To rectify this, it is imperative that changes be made to the educational system (Schleicher, ed., 2012). Looking at countries that are consistently at the top is one way to find potential solutions and models of reform. One country that has successfully reformed their educational system is Finland. Within their educational system, the strategies of collaboration and communication are widely utilized by the instructors as well as the students (Sislian, Gabardo, Macedo, & Ribeiro, 2015). While analyzing a single country’s instructional program can give insights into what makes it successful, it is beneficial to compare that country to others that are also achieving success in order to determine any trends and commonalities. The countries used for this comparison were chosen because they were different culturally, geographically, and politically, but in spite of their differences, they were among the top-scoring nations on the PISA

Legal determinants of external finance revisited : the inverse relationship between investor protection and societal well-being

This paper investigates relationships between corporate governance traditions and quality of life as measured by a number of widely reported indicators. It provides an empirical analysis of indicators of societal health in developed economies using a classification based on legal traditions. Arguably the most widely cited work in the corporate governance literature has been the collection of papers by La Porta et al. which has shown, inter alia, statistically significant relationships between legal traditions and various proxies for investor protection. We show statistically significant relationships between legal traditions and various proxies for societal health. Our comparative evidence suggests that the interests of investors may not be congruent with the interests of wider society, and that the criteria for judging the effectiveness of approaches to corporate governance should not be restricted to financial metrics

Advice from a Medical Expert through the Internet on Queries about AIDS and Hepatitis: Analysis of a Pilot Experiment

BACKGROUND: Advice from a medical expert on concerns and queries expressed anonymously through the Internet by patients and later posted on the Web, offers a new type of patient–doctor relationship. The aim of the current study was to perform a descriptive analysis of questions about AIDS and hepatitis made to an infectious disease expert and sent through the Internet to a consumer-oriented Web site in the Spanish language. METHODS AND FINDINGS: Questions were e-mailed and the questions and answers were posted anonymously in the “expert-advice” section of a Web site focused on AIDS and hepatitis. We performed a descriptive study and a temporal analysis of the questions received in the first 12 months after the launch of the site. A total of 899 questions were received from December 2003 to November 2004, with a marked linear growth pattern. Questions originated in Spain in 68% of cases and 32% came from Latin America (the Caribbean, Central America, and South America). Eighty percent of the senders were male. Most of the questions concerned HIV infection (79%) with many fewer on hepatitis (17%) . The highest numbers of questions were submitted just after the weekend (37% of questions were made on Mondays and Tuesdays). Risk factors for contracting HIV infection were the most frequent concern (69%), followed by the window period for detection (12.6%), laboratory results (5.9%), symptoms (4.7%), diagnosis (2.7%), and treatment (2.2%). CONCLUSIONS: Our results confirm a great demand for this type of “ask-the-expert” Internet service, at least for AIDS and hepatitis. Factors such as anonymity, free access, and immediate answers have been key factors in its success

Political Regimes and Sovereign Credit Risk in Europe, 1750-1913

This article uses a new panel data set to perform a statistical analysis of political regimes and sovereign credit risk in Europe from 1750 to 1913. Old Regime polities typically suffered from fiscal fragmentation and absolutist rule. By the start of World War I, however, many such countries had centralized institutions and limited government. Panel regressions indicate that centralized and?or limited regimes were associated with significant improvements in credit risk relative to fragmented and absolutist ones. Structural break tests also reveal close relationships between major turning points in yield series and political transformations

Selective inhibition of T suppressor-cell function by a monosaccharide

Interactions between regulatory T lymphocytes and other cells are assumed to occur at the level of the cell surface. T cells which suppress the generation of specifically effector cells have been described as having antigenic, idiotypic, allotypic and I-region specificity1−4. Other T suppressor cells generated by in vitro cultivation with or without mitogenic stimulation5,6 have suppressive activity for T and B cells but no specificity can be assigned to them. These T suppressor cells (Ts) inhibit various lymphoid functions—this either reflects their polyclonal origin or indicates that the structures recognized by the Ts receptors must be common for many cell types. Carbohydrates on cell membrane-inserted glycoproteins or glycolipids might function as specific ligands for recognition by cellular receptors or soluble factors. Almost all cell-surface proteins of mammalian cells are glycosylated. There is evidence for lectin-like carbohydrate binding proteins not only in plants7 but also in toxins8, viruses9, prokaryotic cells10 and even mammalian cells, including T cells11. A functional role for these lectin-like proteins has been described for slime moulds and suggested for the selective association of embryonic cells12,13. We report here that addition of a monosaccharide can counteract the effect of T suppressor cells during the generation of alloreactive cytotoxic T cells (CTLs) in vitro

Discovering transcriptional modules by Bayesian data integration

Motivation: We present a method for directly inferring transcriptional modules (TMs) by integrating gene expression and transcription factor binding (ChIP-chip) data. Our model extends a hierarchical Dirichlet process mixture model to allow data fusion on a gene-by-gene basis. This encodes the intuition that co-expression and co-regulation are not necessarily equivalent and hence we do not expect all genes to group similarly in both datasets. In particular, it allows us to identify the subset of genes that share the same structure of transcriptional modules in both datasets. Results: We find that by working on a gene-by-gene basis, our model is able to extract clusters with greater functional coherence than existing methods. By combining gene expression and transcription factor binding (ChIP-chip) data in this way, we are better able to determine the groups of genes that are most likely to represent underlying TMs

National neonatal resuscitation training program in Nigeria (2008-2012): A preliminary report

Background: Routine institutional training of doctors and nurses on newborn resuscitation have commenced, to improve the quality of resuscitation available to high-risk babies, in Nigeria, as a means of reducing newborn deaths in the country. Perinatal asphyxia contributes to 26% of newborn deaths in Nigeria. Perinatal asphyxia results when babies have difficulty establishing spontaneous respiration after birth.Materials and Methods: Between 2008 and 2012, doctors and nurses drawn from all the geo.political zones were trained using the Neonatal  Resuscitation Training (NRT) manual of the American Heart Association and the American Academy of Pediatrics. Questionnaire.based, cross.sectional surveys of doctor and nurse trainees from the six geo.political zones in Nigeria were conducted eight months after the primary training, to evaluate the post.training  neonatal resuscitation activities.Results: Over the period of study, 357 doctors and 370 nurse/midwives were primarily trained in NRT. The overall ratio of step down training was 1:22 with 1:18 for doctors and 1:26 for nurses. In 2008, the delivery attendance rates were 11 per doctor and 9 per nurse/midwife. These rates increased to 30 per doctor and 47 per nurse in 2012. Between 88 and 94% of the doctors and between 72 and 93% of the nurses successfully used bag and mask to help babies breathe in the post.training period. The nurses used bag and mask for infant resuscitation more frequently,   compared to doctors, with the rate fluctuating between two.to.one and four.to.one. Over the years, 87 to 94% of the doctors and 92 to 97% of the nurses/midwives trained other birth attendants.Conclusion: The NRT in Nigeria is well.subscribed and the frequency of secondary training is good.Key words: Birth asphyxia, birth attendants, delivery room care, neonatal resuscitation training, perinatal mortalit
