Devaluation, competitiveness and new business formation in emerging countries

In September 2010, Brazil’s Finance Minister, Guido Mantega, used the term “currency war” with reference to monetary policies implemented by different countries to generate an artificial devaluation of their currency and achieve a cheaper, more competitive domestic economy that may be attractive to foreign investors. Similar cases have been documented since the 1930s Great Depression, when several countries abandoned the gold standard as backing for their currencies. More recently, a large-scale asset purchase by Japan’s Central Bank in 2013 was singled out as a strategy aimed at generating devaluation of the yen. This research uses statistics of new business formation density reported by Doing Business for 30 emerging countries in the period 2004-2011 to evaluate the impact of devaluation measured by the behavior of the real effective exchange rate (REER) on the rate of new business formation (NBF). It is determined how variables associated with competitiveness affect the relationship between devaluation and business formation. Results show that devaluation has a positive effect on NBF in the short term, which gets diluted in the long term. Countries with greater competitiveness have less dependence on devaluation to increase the number of businesses.

Size effects on self-assembly and melting of silver-alkanethiolate on inert surfaces

Self-assembled materials produced in the reaction between alkanethiol and Ag are characterized and compared. It is revealed that the size of the Ag substrate has a significant role in the self-assembly process and determines the reaction products. Alkanethiol adsorbs on the surface of Ag continuous planar thin films and only forms self-assembled monolayers (SAMs), while the reaction between alkanethiol and Ag clusters on inert surfaces is more aggressive and generates a significantly larger amount of alkanethiolate. Two dissimilar products are yielded depending on the size of the clusters. Small Ag clusters are more likely to be converted into multilayer silver-alkanethiolate (AgSR, R = CnH2n+1) crystals, while larger Ag clusters form monolayer-protected clusters (MPCs). The AgSR crystals are initially small and can ripen into large lamellae during thermal annealing. The crystals have facets and flat terraces with extended area, and have a strong preferred orientation in parallel with the substrate surface. The MPCs move laterally upon annealing and reorganize into a single-layer network with their separation distance approximately equal to the length of an extended alkyl chain. AgSR lamellar crystals grown on inert surfaces provide an excellent platform to study the melting characteristics of crystalline lamellae of polymeric materials with the thickness in the nanometer scale. This system is also unique in that each crystal has integer number of layers – magic-number size (thickness). The size of the crystals is controlled by adjusting the amount of Ag and the annealing temperature. X-ray diffraction (XRD) and atomic force microscopy (AFM) are combined to accurately determine the size (number of layers) of the lamellar crystals. The melting characteristics are measured with nanocalorimetry and show discrete melting transitions which are attributed to the magic-number sizes of the lamellar crystals. The discrete melting temperatures are intrinsic properties of the crystals with particular sizes. Smaller lamellar crystals with less number of layers melt at lower temperatures. The melting point depression is inversely proportional to the total thickness of the lamellae – the product of the number of layers and the layer thickness.

Adaptation and validation into Portuguese language of the HIV Antibody Testing Attitude Scale

Objective. To culturally adapt and validate a version in European Portuguese language of the HIV Antibody Testing Attitude Scale. Methods. Study conducting a methodological investigation for the adaptation and validation of an attitude measurement instrument. The instrument translation and back-translation were performed. Then, a pre-test was conducted. The study used a sample of 317 subjects from the academic community - students, professors and other professionals - who were contacted in the campus. Ethical principles were observed. Results. Three analyses were conducted using the method of principal component analysis (PCA) with five, four and three factors. A three-factor solution was achieved, which presents 50.82% variance. In the analysis of inter-item correlation, values between -0.018 and 0.749 were observed. Internal consistency shows Cronbach’s alpha coefficients of 0.860 overall and between 0.865 and 0.659 in the three factors. Conclusion. The instrument version shows psychometric properties that allow its use in Portuguese-speaking countries.

The impact of internet addiction on the mental health of college students from the central area of Portugal

Introduction: Mental health has an imperative roll in general health, and it’s known that most mental and physical diseases are influenced by a combination of biological, psychological and social factors, in which takes place the Internet addiction. Objectives: identify the sociodemographic variables that influence the mental health of college students; identify academic variables that influence the mental health of college student. Methods: Quantitative, descriptive-analytical and cross-sectional study with 511 college students of the Central Region of Portugal. It was used a questionnaire on sociodemographic and academic context, and were used the following scales: Mental Health Scale – PhD José Luís Pais Ribeiro (2011); Internet Addiction Test, Portuguese version by Pontes e Patrão (2013). Results: Mostly female students, standing largely in the age group of 17-21 years, living in urban areas, with an average family income. Younger students have high addition to the internet (62.2%). Sex interfere with the mental health of students. The lower the negative impact of adding Internet emotions / feelings and lower its negative impact on daily life, the less anxiety, depression and loss of emotional / behavioral control of college students. The negative impact on daily life establishes a direct relationship with the positive affect, indicating that the greater the negative impact, less positive affect students. Conclusions: The results obtained point to the need to implement mental health programs, by conducting two workshops, promoting social interaction among students, to help them find more effective ways to respond to the daily challenges.

Relationship between religiosity, religious coping and socio-demographic variables among out-patients with depression or diabetes mellitus in Enugu, Nigeria.

Background: Religion is a powerful coping strategy. Diabetes and depression are common conditions in our environment that induce psychological distress, thus requiring coping for better outcome. Studies indicate that increased religiosity is associated with better outcome in clinical and general populations. Therefore, studies of the distribution of religiosity and religious coping among these populations are essential to improve outcome. Objectives: To assess the association between religiosity, religious coping in depression and diabetes mellitus, and selected sociodemographic variables (age, gender and occupational status). Methods:Using simple random sampling we recruited 112 participants with diabetes and an equal number with depression consecutively, matching for gender. Religiosity was determined using religious orientation scale (revised), religious coping with brief religious coping scale and socio-demographic variables with a socio-demographic questionnaire. Results: Intrinsic religiosity was greater among older people with depression than among older people with diabetes(t=5.02,p<0.001); no significant difference among young people with depression and diabetes(t=1.47,p=0.15).Positive religious coping was greater among older people with depression than among older people with diabetes(t=2.31,p=0.02); no difference among young people with depression and diabetes(t=0.80,p=0.43). Females with depression had higher intrinsic religiosity scores than males with depression(t=3.85,p<0.001); no difference in intrinsic religiosity between females and males with diabetes(t=0.99,p=0.32).Positive religious coping was greater among participants with diabetes in the low occupational status(t=2.96,p<0.001) than those in the high occupational status. Conclusion: Religion is indeed a reliable coping method, most commonly used by the elderly and females with depression. Positive religious coping is more common among diabetic patients who are in the low occupational status.

Children's Separation Anxiety Scale (CSAS): Psychometric Properties

This study describes the psychometric properties of the Children's Separation Anxiety Scale (CSAS), which assesses separation anxiety symptoms in childhood. Participants in Study 1 were 1,908 schoolchildren aged between 8 and 11. Exploratory factor analysis identified four factors: worry about separation, distress from separation, opposition to separation, and calm at separation, which explained 46.91% of the variance. In Study 2, 6,016 children aged 8–11 participated. The factor model in Study 1 was validated by confirmatory factor analysis. The internal consistency (α = 0.82) and temporal stability (r = 0.83) of the instrument were good. The convergent and discriminant validity were evaluated by means of correlations with other measures of separation anxiety, childhood anxiety, depression and anger. Sensitivity of the scale was 85% and its specificity, 95%. The results support the reliability and validity of the CSAS.

Personality of the caregiver influences the use of strategies to deal with the behavior of persons with dementia

Personality of family caregiver is an important factor influencing the caregiver's burden, depression and distress. We now hypothesized that the personality is associated with specific strategies used by family caregivers to deal with the behavioral and psychological symptoms of demented relatives (BPSD). Participants were 98 consecutive persons with dementia and their family caregivers. Assessments included: Personality (NEO-FFI), Burden (ZBI), Depression (CES-D), Cognitive Function (MMSE), BPSD (NPI), Distress (NPI-D), and an open question to identify the strategies used by caregivers when faced with BPSD. Caregivers used different strategies to cope with their relatives' behavior: avoiding conflict; confronting; reassuring; orienting; responding coercively; distracting; colluding; medicating and restricting the movements. Extraversion was the only dimension of caregiver's personality that determined the use of caregiver strategies to deal with BPSD. Extroverted caregivers used the "confronting" strategy less often. Caregiver's personality should be taken into account when designing adapted intervention programs.

The Prevalence of Depression among patients and its detection by Primary Health Care Workers at Matawale Health Centre (Zomba)

Background Little information is available on the prevalence of depression in Malawi in primary health care settings and yet there is increased number of cases of depression presenting at tertiary level in severe form. Aim The aim of the study was to determine the prevalence of depression among patients and its detection by health care workers at a primary health care clinic in Zomba. Methods A cross-sectional survey was done among patients attending outpatient department at Matawale Health Centre, in Zomba from 1st July 2009 through to 31st July 2009. A total of 350 adults were randomly selected using systematic sampling. The “Self Reporting Questionnaire”, a questionnaire measuring social demographic factors and the Structured Clinical Interview for DSM-IV Axis I disorders Non-Patient Version (SCID-NP) were administered verbally to the participants. Findings The prevalence of depression among the patients attending the outpatients department was found to be 30.3% while detection rate of depression by clinician was 0%. Conclusion The results revealed the magnitude of depression which is prevalent in the primary health care clinic that goes undiagnosed and unmanaged. It is therefore recommended that primary health care providers do thorough assessments to address common mental disorders especially depression and they should be educated to recognise and manage depression appropriately at primary care level.
