The Influence of Water Access in Subjective Well-Being: Some Evidence in Yucatan, Mexico

The literature on happiness or subjective well-being has explored the determinants of happiness without taking into consideration the role that water plays. In this paper we attempt to draw attention to water in subjective well-being studies. Approximately one hundred million people do not have access to water. A lack of clean water causes diseases such as diarrhea and cholera, responsible for around 5% of the total deaths in the world. Access to water should therefore be a necessary asset in life. In order to consider access to water, we estimate its influence on subjective well-being using data from rural Yucatan, Mexico. Residents in Yucatan suffer from low quality access to water and there are also imperfections in the management of the service, such as water cuts. We estimate the influence of water on subjective well-being, finding a positive and significant relationship. In a second stage of the research, we relate water access variables to subjective well-being, the health and the water domain of life, finding significant results. These results make it possible to formulate political measures concerning access to water and happiness maximization. We demonstrate that access to water is important for well-being in Yucatan and might be important in many other places; we therefore encourage future research to contemplate water satisfaction and water variables in their analysis.     

Grandmothers Offering Regular Auxiliary Care for Their Grandchildren: An Expression of Generativity in Later Life?

The study explores the meaning that grandmothers who offer regular childcare attach to that experience and the extent to which the notion of generativity might explain the meaning of the experience of caring for a grandchild. Twenty-four Spanish grandmothers aged 60 and over who provided at least 12 hours a week of childcare were interviewed. Interviews were transcribed verbatim and qualitatively analyzed. The results suggest that grandmothers regard their childcare input as being part of their parental duty of helping in times of need. A range of consequences of caregiving were mentioned, generally positive and satisfactory. Our participants apparently began their caregiving task as an expression of parental generativity, although rewards associated with childcare are linked to grandparental generativity.     

A comparison of three physical activity programs for health and fitness tested with older women: Benefits of aerobic activity,aqua fitness,and strength training

ABSTRACT

Inactivity has been associated with decreased quality of life of older people, and many physical activity programs are encouraged. However, the heterogeneity of the different exercise programs available is well recognized. The objective was to compare three physical activity programs (strength training, aqua fitness, and aerobic exercise) to discern the differences in the benefits achieved by each of them in older women over a period of 6 months. For that, a double-blind randomized trial sorted 347 women over 50 years old into three groups of exercise programs; they completed three sessions of evaluation that included the measurement of weight and body mass index and used the Senior Fitness Test (SFT) and SF-12 questionnaire. A t-test for related samples compared the evolution of each group, and ANOVA statistic was used to compare the effect of the different exercise programs. The results showed that women should consider performing aerobic activity up to age 60. After that age, aerobic activity or strength training can provide greater benefits.

A newsboy problem with an emergency order under a general backorder rate function

In this paper, a generalization is presented of the newsboy problem where an emergency lot can be ordered to provide for a certain fraction of shortage. This fraction is described by a general backorder rate function which is non-increasing with respect to the unsatisfied demand. An exponential distribution for the demand during the selling season is assumed. An expression is obtained in a closed form for the optimal lot size and the maximum expected profit. A general sensitivity analysis of the optimal policy with respect to the backorder rate function and the parameters of the inventory system is developed. When the backorder rate function is described by some particular functions, its behavior is analyzed with respect to changes in the parameters. To illustrate the theoretical results, some numerical examples are also given.     

Manufacturing flexibility and advanced human resource management practices

This article analyses the connection between the use of advanced human resource management (HRM) practices, individually and as a system, with manufacturing flexibility. The results show a positive relationship between the implementation of advanced HRM practices and manufacturing flexibility. While most of the advanced HRM practices analysed show higher levels of implementation in flexible firms, no differences are observed in training efforts. Flexible firms are more prone to implement systems of advanced HRM practices.     

Organizational structure and success of international joint ventures in emerging economies: the case of Spanish–Moroccan SMEs

One of the most common ways in which SMEs internationalize their business is through the creation of joint ventures; nevertheless, many of these fail. To avoid this risk, it is important to identify the factors that favour the continuity of such enterprises. The aim of this paper is to analyse the factors related to organizational structure that determine the success of international joint ventures between SMEs in emerging economies, taking as the particular area of study the question of joint ventures between Spanish and Moroccan firms, located in Morocco. The research hypotheses were tested using a linear regression model applied to a sample of 210 international joint ventures. The results obtained from a structured survey show that, with respect to the success of the partnership, significant factors include the existence of majority ownership by the foreign partner, management by a local CEO and the effort made by each party to adapt to the management style of the other. This research contributes to the knowledge of the main factors related to the organizational structure of joint ventures that influence the level of success achieved. The value provided by this research lies in the breadth of the sample examined, in its focus on a very common type of partnership between SMEs, on which very little has been previously studied, and in the fact that the results obtained are extensible to other realities, such as partnerships between European companies and those from countries with similar characteristics (located in Africa or in countries where an Arab culture prevails).     

Pretending emotions in the early years: The role of language and symbolic play

Although 3-year-old children sometimes simulate emotions to adapt to social norms, we do not know if even younger children can pretend emotions in playful contexts. The present study investigated (1) what emotions infants of 1–2 years old are capable of pretending and (2) the possible role of language and symbolic play in the ability to pretend emotions. The sample included 69 infants aged 18 to 31 months and their parents. Infants were administrated the Test of Pretend Play, and their parents responded to the MacArthur-Bates CDI-II inventory, part of the MacArthur-Bates CDI-I, and a questionnaire about the expression of pretend emotions. Results suggest that very young children simulate emotions. Furthermore, children's simulation of emotions was related to both symbolic play and language. Specifically, the ability to label emotions was linked to the ability to simulate them. The role of language and symbolic play in the development of the capacity to express and understand pretend emotions is discussed.     

Coverage with k-transmitters in the presence of obstacles

For a fixed integer k≥0, a k-transmitter is an omnidirectional wireless transmitter with an infinite broadcast range that is able to penetrate up to k “walls”, represented as line segments in the plane. We develop lower and upper bounds for the number of k-transmitters that are necessary and sufficient to cover a given collection of line segments, polygonal chains and polygons.     

Comparative assessment of analytical approaches to quantify the risk for introduction of rare animal diseases: the example of avian influenza in Spain

Trade of animals and animal products imposes an uncertain and variable risk for exotic animal diseases introduction into importing countries. Risk analysis provides importing countries with an objective, transparent, and internationally accepted method for assessing that risk. Over the last decades, European Union countries have conducted probabilistic risk assessments quite frequently to quantify the risk for rare animal diseases introduction into their territories. Most probabilistic animal health risk assessments have been typically classified into one-level and multilevel binomial models. One-level models are more simple than multilevel models because they assume that animals or products originate from one single population. However, it is unknown whether such simplification may result in substantially different results compared to those obtained through the use of multilevel models. Here, data used on a probabilistic multilevel binomial model formulated to assess the risk for highly pathogenic avian influenza introduction into Spain were reanalyzed using a one-level binomial model and their outcomes were compared. An alternative ordinal model is also proposed here, which makes use of simpler assumptions and less information compared to those required by traditional one-level and multilevel approaches. Results suggest that, at least under certain circumstances, results of the one-level and ordinal approaches are similar to those obtained using multilevel models. Consequently, we argue that, when data are insufficient to run traditional probabilistic models, the ordinal approach presented here may be a suitable alternative to rank exporting countries in terms of the risk that they impose for the spread of rare animal diseases into disease-free countries.
