Physical consequences of falls in the elderly: a literature review from 1995 to 2010

In the last decade, population ageing has been registered as a global phenomenon. A relation exists between falling and ageing, since falling frequency increases significantly with age. In fact, one in three older adult falls annually. Although ageing is generically associated with decrease and degeneration of psychological and physical functions, it is still not common for the correct identification of risk factors to lead to a clinical prognosis of the elder being in risk of falling. Therefore, the goal of this review article is to identify, categorise and analyse typical ageing and fall factors mentioned in the literature as well as to quantify the number of times they were referenced. The research considered hundreds of publications, but analysis was then restricted to the 87 most pertinent articles written in English and published in journals or scientific magazines between 1995 and 2010. We concluded that falls among older adults can be characterised by the following: anatomic characteristics and physiological consequences of ageing; the pathologies that induce falls, which can be neurological, musculoskeletal, cardiovascular and other diseases; causes and risk factors of falls that can be behavioural, biological, environmental or socio-economic; type of physical consequences of falls, including fractures, bruises, injuries or other physical consequences; and strategies to prevent, mitigate or rehabilitate, which can be of a physical, environmental or behavioural nature.     

Female board appointments and firm valuation: short and long-term effects

The presence of women on boards of directors has become a high profile issue in recent years. Several studies, based largely on data from countries with Anglo-Saxon corporate governance systems, have investigated the influence of female board appointments on firm performance. This study focuses on the impact of female directors in Spain, where debate about this topic has been intense for two reasons: the recommendation in 2006 by Spain’s Unified Good Governance Code of positive discrimination in favour of female board appointments and the passing in 2007 of a Gender Equality Act by the Spanish parliament. Our paper analyses the short and long term effect of the appointment of female directors prior to these events. We use an event study to analyze the short term stock market reaction to the appointment of female directors and a multiple regression approach, using the system GMM estimation procedure, to assess the long term influence on firm value of female boardroom appointments. We find that the stock market reacts positively in the short term to the announcement of female board appointments, suggesting that investors on average believe that female directors add value. This belief appears to be confirmed by our regression results which show that female board appointments are positively associated with firm value over a sustained period. These results suggest that the legislative changes in Spain make economic sense as well as advancing the cause of women in Spanish boardrooms.     

Primed for Change: Facilitating Factors in Problem Gambling Treatment

To successfully facilitate the treatment of problem gambling, change processes should be examined in order to identify those variables that differentiate good versus poor treatment outcomes. The current study explored the change facilitating effects of certain characteristics or conditions of an individual being treated: emotional support, instrumental support, emotional awareness, GA involvement, and depressed affect. These conditions were hypothesized to be predictive of a change-oriented mindset (i.e., “resources for change”) measured by abstinence self-efficacy, motivation for change, and readiness for change. Participants were 60 outpatients (54.2% male; M age = 46.7 years) with problem gambling recruited from several treatment centres throughout Ontario, Canada. Results indicated that: (1) depressed affect and emotional support seem to influence self-efficacy for abstinence, (2) emotional support alone appears to influence motivation for change, and (3) GA involvement, depressed affect, and emotional awareness, together, seem to influence readiness for change. These findings have implications for promoting change oriented dispositions in problem gambling individuals.     

Work–family Conflicts and the Organizational Work Culture as Barriers to Women Educational Managers

This article examines perceived barriers and the influence they play in the professional and personal lives of women educational managers in Spain. A survey of 206 female school heads from pre‐primary and primary schools shows that the women administrators face several perceived barriers: a lack of support from the governing educational authority; insufficient preparation and in‐service training and an absence of equity‐based support policies from the government and reconciliation policies to make the dual roles of mother–professional compatible. The study further found that role conflict and certain features of the organizational work culture, particularly the management culture, which was generally perceived as strongly masculine, and the scant appreciation of administrative work compared with teaching, were the factors that contributed to delaying or avoiding accession to the post of headship in schools.     

On the integrated maximum likelihood estimators for a closed population capture–recapture model with unequal capture probabilities

Nuisance parameter elimination is a central problem in capture–recapture modelling. In this paper, we consider a closed population capture–recapture model which assumes the capture probabilities varies only with the sampling occasions. In this model, the capture probabilities are regarded as nuisance parameters and the unknown number of individuals is the parameter of interest. In order to eliminate the nuisance parameters, the likelihood function is integrated with respect to a weight function (uniform and Jeffrey's) of the nuisance parameters resulting in an integrated likelihood function depending only on the population size. For these integrated likelihood functions, analytical expressions for the maximum likelihood estimates are obtained and it is proved that they are always finite and unique. Variance estimates of the proposed estimators are obtained via a parametric bootstrap resampling procedure. The proposed methods are illustrated on a real data set and their frequentist properties are assessed by means of a simulation study.     

The influence of comorbidities on the aging males’ symptoms scale in patients with erectile dysfunction

Objectives: To investigate if certain common age-related comorbidities are related with a positive aging males’ symptoms (AMS) test outcome.

Methods: This was a multicentric, transversal, observational study carried out in a male population with erectile dysfunction. Comorbidities and testosterone levels were registered. The relationship between comorbidities, testosterone levels, and the AMS test outcomes was studied using the global score and the sub-scale score components.

Results: The study included 1112 patients. In the multivariate analysis the global score strongly correlated with TT?p?Conclusion: Although the AMS test is related to low levels of testosterone, it is also of some limited use for diagnosing hypogonadism because it has low specificity and is influenced by pathologies that are frequent during ageing.     

Mortality and Macroeconomic Fluctuations in Contemporary Sweden

Recent research has provided strong evidence that, in the United States in particular and in high- or middle-income economies in general, mortality tends to evolve better in recessions than in expansions. It has been suggested that Sweden may be an exception to this pattern. The present investigation shows, however, that in the period 1968?C2003 mortality oscillated procyclically in Sweden, deviating from its trend upward during expansions and downward during recessions. This pattern is evidenced by the oscillations of life expectancy, total mortality, and age- and sex-specific mortality rates at the national level, and also by regional mortality rates for the major demographic groups during recent decades. Results are robust for different economic indicators, methods of detrending, and models. In lag regression models macroeconomic effects on annual mortality tend to appear lagged 1 year. As in other countries, traffic mortality rises in expansions and declines in recessions, and the same is found for total cardiovascular mortality. However, macroeconomic effects on ischemic heart disease mortality appear at lag two and are hard to interpret. Reasons for the procyclical oscillations of mortality, for inconsistent results found in previous studies, as well as for the differences observed between Sweden and the United States are discussed.     

Tax and Structural Reforms in the Transition from Command to Market Economy

The purpose of this paper is to verify the validity of a pessimistic view (Blanchard in The economics of transition in Eastern Europe, Clarendon Press, Oxford, 1997) on the role played by public finance in meeting and distributing the costs of transition from command to market economy. In conclusion, we may say that, even though referring to the specific case of Albania, the model of the structural reform index allows us to discuss alternative views on the nature and causes of the impact of the fiscal phenomena on the transition process. The findings were confirmed, using the Bagnai method, by the real evolution of the Albanian economy, and by the valuations of the World Bank and the IMF, both recognizing the importance of the fiscal factor.
