PHARMACEUTICAL BENEFITS IN AUSTRALIA AND SWEDEN: WELFARE POLICY AND THE COST OF PRESCRIPTION DRUGS

Pharmaceutical benefits provide a stable framework within which consumers, prescribers, suppliers, pharmacists and other actors undertake transactions. The state in effect delivers a good that enhances individual autonomy. A major reason for the legitimacy enjoyed by pharmaceutical benefits in both Australia and Sweden is that these programs have strong attributes of universalism (rather than targeting). Sweden's predominantly public health system allows greater scope for pharmaceutical policy innovation. Australia's Pharmaceutical Benefits Scheme (PBS), while historically resilient and effective, is now wedged precariously between traditional considerations of equity and public health on the one hand, and constant pressure for increased marketisation on the other.     

Developing a Social Capital Index for the Netherlands

This paper integrates a set of independent social capital indicators into one index by using structural equation modeling (SEM) based on partial least squares estimation (PLS). The social capital index consists of two dimensions: participation and trust. In each of the two dimensions, three levels are distinguished: social (micro), organizational (meso), and political (macro). The main objectives of the index are to: (1) provide a coherent overview of social capital in the Netherlands; (2) monitor social capital over time; and (3) compare subpopulations. A broad spectrum of indicators is included, however, these are only weakly correlated and consequently treated as distinct. Therefore, traditional index development methods such as factor analysis and reflective modeling cannot be applied. Consequently, formative modeling in which the indicators are specified as causes rather than as effects is used. We employ the Permanent Survey on Living Conditions 2009 (POLS), administered face-to-face to 7,560 respondents in the Netherlands. We find that the index predicts well-being and health, which demonstrates nomological validity. Subsequently, bootstrapping is conducted to test the robustness of the index. And the 2009 index is replicated based on the 2010 POLS data. The replication shows that the 2009 model is relatively stable and results are robust. Finally, the model is extended by including volunteering and informal help, which changes the model but the results remain largely the same. This index, which is shown to be valid and robust, contributes to a further understanding of the concept of social capital.     

Nash Equilibrium with Lower Probabilities

We generalize the concept of Nash equilibrium in mixed strategies for strategic form games to allow for ambiguity in the players' expectations. In contrast to other contributions, we model ambiguity by means of so-called lower probability measures or belief functions, which makes it possible to distinguish between a player's assessment of ambiguity and his attitude towards ambiguity. We also generalize the concept of trembling hand perfect equilibrium. Finally, we demonstrate that for certain attitudes towards ambiguity it is possible to explain cooperation in the one-shot Prisoner's Dilemma in a way that is in accordance with some recent experimental findings.     

Learning effects in coders and their implications for managing content analyses

From the perspective of study management, research is surprisingly lacking on two of the major challenges for planning and performing content analysis: determining the sample size (i.e. number of objects to code) and the required number of coders to hire. The optimization of both of these numbers will ultimately determine how efficiently available resources are used. This study contributes to the methodological discussion on coding by identifying and conceptualizing the role of learning effects with respect to the coding task and by highlighting the importance of considering the coding process when managing a content analysis. We present empirical evidence for the existence and impact of learning effects on coders’ coding speed. Accordingly, study management should take account of learning effects when determining the sample size and number of coders. We also provide an illustrative example of how learning effects can impact the results of pretests.     

Reliability and effects of muscular pretension on isometric strength of older adults

There were two objectives to this study: (a) to determine the reliability of measuring isometric maximum torque (MT) and maximum rate of torque development (MRTD) of the knee extensor and flexor muscles and (b) to assess the effects of different muscular pretensions on MT and MRTD of older adults. Maximum strength of 35 untrained healthy older adults (aged 66.9?±?6.6 years; height 1.72?±?0.07 m; weight 75.2?±?9.6 kg) was measured. Strength measurement was performed with the Dr. Wolff ISO Check using a piezo-electric force transducer. MT intra-day coefficient of variation (CV) was between 3.30 and 12.40 % for both measurement sessions. Intraclass correlation coefficients (ICC) ranging from 0.71 to 0.99 showed good relative reliability. MT test–retest reliability (between sessions 1 and 2) of knee extension reached a CV between 7.10 and 9.30 % and high ICC values. The measurement of the knee flexion achieved an acceptable CV (9.40 %) at 40 % muscular pretension. MRTD was negatively influenced by muscular pretension (p <0.05). In conclusion, MT could be measured reliably over different trials using isometric strength measurement. The test–retest reliability was acceptable at knee extension with 10 to 40 % muscular pretension and with 40 % muscular pretension at knee flexion. A higher muscular pretension has no impact on MT but decreases MRTD in older adults.     

Bargaining cum voice

We propose a formal concept of the power of voice in the context of a simple model where individuals form groups and trade in competitive markets. Individuals use outside options in two different ways. Actual outside options reflect the possibility to exit or to join other existing groups. Hypothetical outside options refer to hypothetical groups that are ultimately not formed. Articulation of hypothetical outside options in the bargaining process determines the relative bargaining power of the members of a group, which constitutes an instance of the power of voice. The adopted equilibrium concept, competitive equilibrium with free group formation and bargaining cum voice, endogenizes the outside options as well as the power of voice. We establish existence of such equilibria and we explore their properties.     

Ähnlich,aber anders

Organizational dynamics and group dynamics exist side by side – they are related to each other and influence each other mutually. This article discusses the relationship between group dynamics and organizational dynamics. We describe eight key differences between groups and organizations that also affect their respective dynamics and reveal the interactions between them. For consultants to play an effective role in organizational dynamics processes, they must first gain access to the organization. There are four possible approaches to doing this.     

Effect of Low‐Income Unmarried Fathers' Presence at Birth on Involvement

The birth of a child represents a unique window of opportunity to understand and support ongoing father involvement among low‐income unmarried parents. Using data collected as part of a randomized controlled trial of a community‐based home visiting intervention provided to 248 low‐income African American women, a propensity score matching approach was used to estimate the effect of fathers' presence at birth on multiple measures of later father involvement over the first 2 years postpartum. The results indicated that participation in child care activities is the only form of involvement predicted by presence at birth at 4 months, and none of the forms of father involvement measured were predicted at 12 months; however, presence at birth was predictive of all 7 indicators of involvement at 24 months. Engaging fathers in the birth experience may represent an important opportunity to provide services.
