The Relationship

The relationship between birthday and deathday has been called an artifact due to the continuous depletion of the population with age. However, while the population decreases with age, the death rate increases. These two influences cancel each other at ages seventy-five to eighty-four. The decreasing population dominates at older ages, but the situation is reversed at younger ages. The results account for no more than one-third of the size of the large-sample effects observed among the elderly. There is still a 33 percent excess of deaths resulting from heart disease among married people ages seventy-five and older in the three-day period centered at the birthday.

AbstractEach child has a task that must be passed well, especially at the age of the child (12-36 months). One of the developmental tasks in toddlers is toilet training. Long-term use of diapers can cause toilet effects. This study aims to determine the relationship between diapers with the ability of toileting in children.The design of this research is Correlation with cross sectional approach. Large sample of 70 respondents. Sampling of the study using total sampling, data collection using questionnaires and calculations using Chi-square Correlation test using SPSS 16.0 error α 0.05.The results of the research variables The use of diapers in children interpreted most of the 47 children of respondents (67.1%) Did not use and almost half of the 23 respondents (32.9%) use. The ability of toileting in children is interpreted by most of the 42 respondents (60.0%) fulfilled, and almost half of 28 respondents (40.0%) are not met.Based on the calculation of Chi-square SPSS statistic shows that p value 0,000 <0,05) means that there is relationship of diaper usage with the ability of toileting in children with the closeness of cc relationship of 0.479 enough category.The results of this study concluded that almost half of them use diapers, and almost half of them do not meet the ability of toileting, the researcher suggests in the research place to put a picture or leaflet about the effect of Diaper Usage on Toileting Ability so that the wise mother in using Diapers.Keywords: diapers, toileting, children AbstrakSetiap anak mempunyai tugas perkembangan yang harus dilewati dengan baik, terlebih pada usia toddler (12-36 bulan).

There is no consensus in theoretical and empirical studies about the relationship between bank competition and stability. This research aims to investigate the relationship between bank competition and stability in the UK. The analysis has been done on a large sample of UK banks for the period 2004–2014. There is quite contrasting evidence on the bank competition and bank soundness relationship. A unified framework has been developed to assess how different factors may make it more likely that the data favor one theory over another. The results suggest that in some cases a U-shaped relationship exists between bank competition and stability. Therefore the conclusion is that in order to protect the bank from different risk exposures a moderate level of bank competition is needed.

The Relationship

We revisit the predictive ability of dividend changes for firms’ future earnings and extend the literature by examining the effect of management forecasting ability. Although prior studies have examined the relationship between dividend changes and future earnings, the empirical evidence is mixed. The belief that dividend changes have implications for future earnings depends on the assumption that managers can accurately assess future earnings prospects. In this regard, we posit that the predictive ability of dividends can vary with managers’ forecasting ability. Analyzing a large sample of Japanese dividend-paying firms, we find that dividend changes, particularly dividend increases, are positively associated with increases in future earnings. Consistent with our hypothesis, this positive association is more pronounced for firms with high-forecasting ability managers. Our findings support the signaling theory of dividend changes and indicate that management forecasting ability has a moderating effect on the linkage between firms’ dividend changes and future earnings.

Heavy Rail

In Europe and in North America, Light Rail Transit (LRT) is increasingly being seen as a viable and attractive transportation option which is not as cost prohibitive as heavy rail, yet carries more passengers and travels at higher speeds than traditional bus transit. Brownfield regeneration is at the forefront of urban land use policy, as cities try to reign in sprawl and address local economic, social, and environmental implications of such underused or abandoned sites. This paper will examine the relationship between the implementation of LRT in urban environments, and how that investment in transportation infrastructure affects the regeneration of urban brownfield sites. This will be achieved through the use of three urban case studies, each with subpopulations between 100,000 – 500,000. Key Words: Light Rail Transit, Brownfield, Transportation, Sustainability, Urban Mobility, Urban Financing, Municipal Plans and Policies.

The Relationship

AbstractThe ventral striatum is believed to encode the subjective value of cost/benefit options; however, this effect has strikingly been absent during choices that involve physical effort. Prior work in freely-moving animals has revealed opposing striatal signals, with greater response to increasing effort demands and reduced responses to rewards requiring effort. Yet, the relationship between these conflicting signals remains unknown. Using fMRI with a naturalistic, effort-based navigation paradigm, we identified functionally-segregated regions within ventral striatum that separately encoded action, effort, and discounting of rewards by effort. Strikingly, these sub-regions mirrored results from a large-sample connectivity-based parcellation of the striatum. Moreover, individual differences in striatal effort activation and effort discounting signals predicted striatal responses to effort-related choices during an independent fMRI task. Taken together, our results suggest that a dorsomedial region primarily associated with action may instead represent the effort cost of actions, and raises fundamental questions regarding the interpretation of striatal “reward” signals in the context of effort demands.

K Giants

Kinematics and abundances have been determined for a large sample of K giants in a field at ∼2 kpc from the center to study the relationship between the bulge and the halo. There are two different kinematic groups evident. The metal-poor stars have low rotation and high velocity dispersion, and so can be associated with the halo. The metal-richer stars have intermediate rotation. Our data suggest that the bulge and halo could be separate kinematical entities.

Gathering Data

Urban mobility is one of the key aspects of urban planning and development. It plays an important role in the achievement of a resilient, inclusive and sustainable city. However, the complex interrelations of urban mobility, transportation and other city dimensions implies the need of an interdisciplinary approach to understand and plan it. In this brief paper, we discuss the social aspects of urban mobility and inequality and how it has been addressed in the literature. We also show different ways of gathering data relevant for the understanding of urban mobility, their sizes, scopes, and nature. Finally, we aim to promote an interdisciplinary debate based on our academic literature review about the relationship of urban mobility with social variables such as poverty.
