Benefiting from Public Sector Innovation: The Moderating Role of Customer and Learning Orientation

This article examines whether the payoff from engaging in innovation‐generating activities is contingent on an organization's level of customer and learning orientation. The authors suggest that innovative activity is associated with higher public service quality when the level of customer and learning orientation within the focal organization is high. They test this hypothesis by drawing on a novel panel data set covering all public nonspecialist hospital organizations in England. Using dynamic panel data estimation techniques, the authors find strong support for a direct relationship between innovative activity and public service quality and for a moderating role of both customer and learning orientation. These findings call for a contingency perspective on public sector innovation and highlight some of the boundary conditions that need to be in place if public service organizations are to benefit fully from their innovative activities.     

A study of the evaporation of a solvent from a solution--application to writing ink aging

When writing ink is placed on a substrate, a drying process begins. This process is dependent on the composition of the ink and of the substrate. Lociciro et al. provide an equation that describes the drying process based on models developed by earlier investigators. The work given here develops an equation for the drying process that is based on a different and rather simple model. This model considers the evaporation of a solution in an opened vertical container (e.g., a beaker) and consists of a volatile, non-hygroscopic solvent with a non-volatile solute dissolved in it. Three assumptions are made: (a) the rate of evaporation is proportional to the vapor pressure of the solution and to the solution's exposed surface area, (b) this solution vapor pressure is proportional to the solvent vapor pressure with the proportionality constant being the solvent mole fraction (Raoult's law), and (c) a small fraction of the solvent remains trapped in the solute after evaporation ceases. What results is a differential equation, which, when solved, gives the solvent weight W(t) as an implicit function. What emerges naturally from this treatment is the fact that the function W(t) can have a point of maximum acceleration. Prior to this point the drying process is fast and after this point, the drying process is slow. An approximation to W(t) is taken to be the sum of two exponential functions, one describing the fast drying region and the second describing the subsequent slow drying region. Upon including an additive constant, this approximation turns out to be similar to, but not the same as that provided by Lociciro et al. However, their equivalence is shown and then tested using the two inks examined by Lociciro et al. (the drying of a Bic and a Staedtler blue ballpoint ink). The examples of (solvent+solute) systems ("inks") given here consist of the solvent (2-phenoxyethanol) and a solute such as a dye (crystal violet) or a polymer resin such as synthetic resin SK or polyvinyl butyral. In the case of polymers, the Raoult's law assumption is replaced with one developed by the Flory-Huggins theory of solutions. Saturation and film formation, both of which slow the evaporation rate, are also discussed.     

The Anti‐Incumbent Effects of Conditional Cash Transfer Programs

Scholars concur that conditional cash transfer (CCT) programs have a strong proincumbent effect among beneficiaries. Although no study has properly focused on the overall effect of cash transfers on incumbents' national vote shares, most scholars have deduced that this effect is positive; i.e., that cash transfers lead to the expansion of incumbents' electoral bases. This article analyzes survey data from nearly all Latin American countries and confirms that beneficiaries of CCT programs are more likely to support incumbents. However, it also shows that CCT programs may induce many voters who were previously incumbent supporters to vote for the opposition. As a consequence, the overall impact of cash transfers on incumbents' vote shares is indeterminate; it depends on the balance between both patterns of behavioral changes among voters. This study is the first to report evidence that cash transfer programs may have significant anti‐incumbent effects.     

Blow Flies from Forest Fragments Embedded in Different Land Uses: Implications for Selecting Indicators in Forensic Entomology

Given the general expectation that forest loss can alter biodiversity patterns, we hypothesize that blow fly species abundances differ in a gradient of native vegetation cover. This study was conducted in 17 fragments across different landscapes in central Brazil. Different land cover type proportions were used to represent landscape structure. In total, 2334 specimens of nine species of Calliphoridae were collected. We used principal component analysis (PCA) to reduce dimensionality and multicollinearity of the landscape data. The first component explained 70%, and it represented a gradient of forest‐pasture land uses. Alien species showed a wide distribution in different fragments with no clear relationship between the abundance values and the scores of PCA axes, whereas native species occurred only in areas with a predominance of forest cover. Our study revealed that certain native species may be sensitive to forest loss at the landscape scale, and they represent a bioindicator in forensic entomology.     

Democracy and dictatorship revisited

We address the strengths and weaknesses of the main available measures of political regime and extend the dichotomous regime classification first introduced in Alvarez et al. (Stud. Comp. Int. Dev. 31(2):3–36, 1996). This extension focuses on how incumbents are removed from office. We argue that differences across regime measures must be taken seriously and that they should be evaluated in terms of whether they (1) serve to address important research questions, (2) can be interpreted meaningfully, and (3) are reproducible. We argue that existing measures of democracy are not interchangeable and that the choice of measure should be guided by its theoretical and empirical underpinnings. We show that the choice of regime measure matters by replicating studies published in leading journals.     

Combinatorics in the theory of utility

It used to be thought that the utility or pleasure that goods gave consumers depended on the whole on the nature of the goods and, particularly, on its quantity. This is half true, half false. The utility obtained from a set of goods depends mainly on how the goods are ordered and combined within the dynamic time sequence represented by consumption. In other words, it depends less on what the goods are and more on how the goods are positioned. Understanding this offers huge possibilities within the theory of utility--and thus of consumption--as it allows us to apply the arsenal of tools available to us in the mathematic speciality known as combinatorics, as applied to utility. If each combination of goods poses a utility, we can rank these combinations differently using ordinal criteria and real transitive preferences. From there we can establish a set of menus, from best to least poor, and, armed with this information, work out a theory of individual choice. This is in brief the purpose of this work.     

Three paradigms in a single monetary circulation

The nature of money is simple and easy to understand, both what it is and what it was; it is the ＂law of gravity＂ we all understand. Many macroeconomic concepts and operations are based on money. Without it, they would be impossible to comprehend and, in fact, can only be understood by methodically tracking the circulation of money. There are three core paradigms of money and money circulation： the money multiplier, the velocity of circulation of money income and the money-income multiplier. In this paper, we try to demystify or decouple some of these circulatory mechanisms in order to establish, to the extent that is possible, a single comprehensive theory. A comprehensive theory or an approximation to such demands that the three economic operations corresponding to the above three paradigms form part of the same monetary macroeconomic phenomenon. To prove workable, it requires that the formulae arrived at being represented by a single mathematical expression. This paper shows that there is a conflict between, on one hand, the inevitable and persistent economic intuition that relates the three paradigms and, on the other, the mathematical formulae （and their components） that occasionally negate this.

WASH and Nutrition Synergies: The Case of Tunisia

This paper develops a simple econometric strategy to operationalise the United Nations Children’s Fund’s (UNICEF’s) conceptual framework for nutrition. It estimates the extent to which child stunting correlates with investments in water, sanitation, and hygiene (WASH) across population groups (poor and nonpoor) and residence (urban and rural). Moving away from estimating single intervention marginal returns, the empirical framework of intervention packages is tested in Tunisia, a country with notable but uneven progress in reducing stunting. A successful nutritional strategy will thereby require mapping the distinctive intervention packages by residence and socio-economic status, away from universal policies, that more strongly correlate with reduction in stunting.
