This article investigates if a party system change has taken place in Spain from June 1977 to January 2019 . The operationalization of Smith’s (1989) definition of party system change requires the distinction between “normal” and “unusual” values of the indicators, which are subject to constant fluctuations . This distinction was achieved by defining unusual values as values that fall outside the area of plus/minus one standard deviation around the mean of the respective indicator . If an indicator’s values are unusual several times in a row, Smith considered it to have undergone change . The distinction between limited and general change as well as a party system transformation depends on how many indicators measure the properties of different party groups that undergo change . The results show that the Spanish party system underwent a series of limited changes from 1977 to 2015 . Despite the following massive shifts in the distribution of seats and the increases in format, this period can only be qualified as one of (weak) general change, but not of party system transformation .

The article attempts to trace the origins and to assess the extent ofparty-system change in Italy in the 1990s. It also examines some hypotheses on the possible causes of such changes. Building on research on anti-party sentiment and on changes in party organization the paper begins with an analysis of the evolution of the party system in the last 30 years which identifies organizational adaptation as a delaying factor in party system change. This is followed by a description of the party system after the 1994 elections based on generally accepted party system characteristics and indicators (volatility, number ofparties, ideological distance) . The assessment is made difficult by the, perhaps temporary, coexistence of two party-systems, respectively relevant for electoral and inter-election competition. The evidence however, suggests, that party-system transformation is under way, while it might still be inappropriate to talk about structural change. Degeneration of parties and a deep institutional crisis appear to be the factors leading to the explosion of pent-up alienation and antiparty sentiments, and to demands for institutional and constitutional change that preceded and appeared to be the immediate causes of party system transformation.

Mean Time

The time course of the appearance of cells showing a new phenotype, following treatment with a specific DNA, has been analyzed. A plot as a function of time of the number of cells showing the new property closely resembles the summation under a normal distribution curve. Describing the appearance of the new phenotype in these terms permits the definition of two parameters, the mean time, and the standard deviation of the distribution curve. This distribution is not affected either by the DNA concentration with which the transformable population has been treated, or by the streptomycin concentration with which the transformed population has been challenged. Interruptions of the expression process, by cooling to 20° or 0°C., serve only to displace the expression curves, without changing their shape, while small reductions in temperature change both the mean time of expression and the standard deviation of the distribution curve. On the basis of these observations a number of hypotheses have been examined concerning the mechanism whereby transforming DNA manifests a phenotypic alteration in the transformed cells. It can be concluded that there exist at least two stages in the process of expression. The completion of the first stage, causing the randomization, occurs with a mean time of about 60 minutes, and a terminal step, that of the transition of phenotype, occurs in less than 3 minutes.

This study deals with an application of the method of the coefficient of variation in strength prediction of the self-piercing riveted joints. Defined as the ratio of the standard deviation to the mean, the coefficient of variation may be used in both the reliability-based design of self-piercing riveted joints and in the evaluation of existing products. In this study, the concept and definition of the coefficient of variation are stated. The procedure of the use of coefficient of variation for approximate calculations of strength of the self-piercing riveted joints is presented and compared with the classical Taylor expansion method. This is illustrated with a numerical example.

Abstract 18F-FDG and 68Ga-citrate PET/CT have both been shown to be useful in the management of tuberculosis (TB). We compared the abnormal PET findings of 18F-FDG- and 68Ga-citrate-PET/CT in patients with TB. Methods Patients with TB on anti-TB therapy were included. Patients had a set of PET scans consisting of both 18F-FDG and 68Ga-citrate. Abnormal lesions were identified, and the two sets of scans were compared. The scan findings were correlated to the clinical data as provided by the attending physician. Results 46 PET/CT scans were performed in 18 patients, 11 (61 %) were female, and the mean age was 35.7 ± 13.5 years. Five patients also had both studies for follow-up reasons during the use of anti-TB therapy. Thirteen patients were co-infected with HIV. 18F-FDG detected more lesions than 68Ga-citrate (261 vs. 166, p < 0.0001). 68Ga-citrate showed a better definition of intracerebral lesions due to the absence of tracer uptake in the brain. The mean SUVmax was higher for 18F-FDG compared to 68Ga-citrate (5.73 vs. 3.01, p < 0.0001). We found a significant correlation between the SUVmax of lesions that were determined by both tracers (r = 0.4968, p < 0.0001). Conclusion Preliminary data shows 18F-FDG-PET detects more abnormal lesions in TB compared to 68Ga-citrate. However, 68Ga-citrate has better lesion definition in the brain and is therefore especially useful when intracranial TB is suspected.

SummaryThe characteristics of experimental error in measurement of platelet radioactivity have been explored by blind replicate determinations on specimens taken on several days on each of three Walker hounds.Analysis suggests that it is not unreasonable to suppose that error for each sample is normally distributed ; and while there is evidence that the variance is heterogeneous, no systematic relationship has been discovered between the mean and the standard deviation of the determinations on individual samples. Thus, since it would be impracticable for investigators to do replicate determinations as a routine, no improvement over simple unweighted least squares estimation on untransformed data suggests itself.

Background: Early marriages are at high risk of marital failure, poor family quality, young pregnancies at risk of maternal death, and the risk of being mentally ill to foster marriage and be responsible parents. Objective: To determine the effect of reproductive health education on peer groups (peers) on the knowledge and perceptions of adolescents about marriage age maturity. Method: This research uses the Quasi experimental method with One group pre and post test design, conducted from May to September 2018. The statistical analysis used in this study is a paired T test with a confidence level of 95% (α = 0, 05). Results: There is an average difference in the mean value of adolescent knowledge between the first and second measurements is 0.50 with a standard deviation of 1.922. The mean difference in mean scores of adolescent perceptions between the first and second measurements was 4.42 with a standard deviation of 9.611. Conclusion: There is a significant difference between adolescent knowledge on the pretest and posttest measurements with a value of P = 0.002, and there is a significant difference between adolescent perceptions on the pretest and posttest measurements with a value of p = 0.001. Increasing the number of facilities and facilities related to reproductive health education by peer groups (peers) in adolescents is carried out on an ongoing basis at school, in collaboration with local health workers as prevention of risky pregnancy.

Institutional Reforms

This final chapter draws out the two main conclusions from the book. First, it discusses the policy implications of its findings. It suggests caution in the decentralization of political authority as a remedy for democratic underperformance in patronage-based democracies. Rather than making government more accountable, it may instead exacerbate principal–agent conflicts between center and periphery. More important than decentralization in the short term may be institutional reforms at the center that make parties more programmatic and responsive to citizens. Second, it sets out some of the implications of the book’s findings for the study of populism and party-system change more generally. It shows that the varied ways in which voters and parties are linked creates different pathways to the decline of establishment parties and the success of populist alternatives. Further comparative research across party systems might contribute positively to institutional reform and political change.
