Party convergence and vote switching: Explaining mainstream party decline across Europe

How can one explain the significant vote losses of mainstream parties across Europe in recent years? In this article, it is argued that mainstream party convergence is an important determinant of the recent political and electoral volatility in European party systems. More specifically, it is hypothesised that as mainstream parties converge on the left-right scale, voters will switch from supporting a mainstream party to a non-mainstream party in the next election as they look for an alternative that better represents their ideological views. To test these theoretical expectations, data is combined from the Comparative Study of Electoral Systems and the Manifestos Project for nearly 15,000 vote choices of individual voters in 30 elections in 16 West and East European countries from 2001 until 2013. The findings have important implications for understanding the recent rise of non-mainstream parties, the changing nature of party systems and the increasing complexity of cabinet formation across Europe.     

What's Love Got To Do With It?: Perceptions of Marital Positivity in H-to-W Aggressive, Distressed, and Happy Marriages

Husbands' and wives' perceptions of positive relationship behaviors and interactions (e.g., caring gestures, reasons for staying married, frequency of positive communication) were assessed in a sample of maritally happy (H), maritally distressed but non-aggressive (D/NA), and maritally distressed and husband-to-wife physically aggressive (D/H-to-W) couples. As expected, the relationship positivity reports of the two groups of maritally distressed couples differed from the happily married couples. In addition, D/H-to-W spouses gave different reasons for staying married than did D/NA spouses (i.e., love versus family roles and commitments). Spouses in D/H-to-W aggressive marriages were also less likely to report using intimate language with their partner than were spouses in either of the other two groups. Few gender differences were found. Results underscore the importance of considering the role of love and intimacy in husband-to-wife aggressive and distressed marriages.     

The Associations Among Family-of-Origin Violence and Young Adults' Current Depressed, Hopeless, Suicidal, and Life-Threatening Behavior

The purpose of the current study was to determine if college students' retrospective reports of family-of-origin physical abuse were related to their current reports of depressed symptomology, hopelessness, and suicidal and life-threatening behavior. Consistent with hypotheses, abuse by a parent (physical and psychological) and physical perpetration toward a parent were associated with increased rates of suicidal and life-threatening behavior. Gender of the parent was also shown to be important as symptoms of depression were related to mother but not father victimization and perpetration. Contrary to expectation, witnessing parental spouse abuse was not associated with young adults' current symptoms of depression, hopelessness, and suicidal and life-threatening behavior. These findings were interpreted with regard to the intergenerational transmission of violence theory.     

Ability, Effort, and Performance Among First-Year Law Students at Brigham Young University

This study considers the relationships between first-year law students' admission credentials, the amount of time they spend in study, and the grades they receive on examination. Findings include that there is a significant drop in effort during the first year, that while effort invested in study pays off in improved grades this effort is much less significant in explaining grades than is student ability as measured by LSAT and undergraduate grades, that students in the middle and bottom of the class are helped more by substantial study than are those in the top, that class attendance is much more valuable in raising grades than is equivalent time in other study, and that none of the various study techniques examined could be linked with major differences in results.     

Mitochondrial DNA regions HVI and HVII population data.

Data from 1393 unrelated individuals have been compiled from eight population groups: African Americans, Africans (Sierra Leone), U.S. Caucasians, Austrians, French, Hispanics, Japanese, and Asian Americans. The majority of the mtDNA sequences were observed only once within each population group (i.e., ranging from a low of 60.3% (35/58) of the Asian American sequences to a high of 85.3% (93/109) of the French sequences). Genetic diversity ranged from 0.990 in the African sample to 0.998 in African Americans. Random match probability ranged from 2.50% in the Asian American sample to 0.52% in U.S. Caucasians. The average number of nucleotide differences between individuals in a database is greatest for the African American and African samples (14.1 and 13.1, respectively), and the least variable are the Caucasians (ranging from 7.2 to 8.4). Substitutions are the predominate polymorphism, and at least 92% of the substitutions are transitions. The most prevalent transversions are As substituted for Cs and Cs substituted for As. For most population groups these transversions occurred predominately in the HVI region; however, the African, African American, and Hispanic samples also demonstrated a large portion of their C to A and A to C transversions in the HVII region (at sites 186 and/or 189). Most insertions occur in the HVII region at sites 309.1 and 315.1, within a stretch of C's. Insertions of an additional C are common in all population groups. The sequence data were converted to SSO mtDNA types and compared with population data on Caucasians, Africans, Asians, Japanese, and Mexicans described by Stoneking et al. [M. Stoneking, D. Hedgecock, R.G. Higuchi, L. Vigilant, H.A. Erlich, Population variation of human mtDNA control region sequences detected by enzymatic amplification and sequence-specific oligonucleotide probes, Am. J. Hum. Genet. 48 (1991) 370-382] using an R x C contingency table test. Differences between major population groups (i.e., between African, Caucasian, and Asian) are quite evident, and similar ethnic population groups carried similar SSO polymorphism frequencies. There were only a few SSO types that showed significant differences between subpopulation groups. The SSO data alone can not be used to describe the population genetics with complete sequence data. However, the results of the SSO comparisons are similar to other analyses, and differences in sequence data in regions HVI and HVII are greater between major population groups than between subgroups.     

Application of Enhanced Point Estimators to a Sample of In Vivo CT‐derived Facial Soft Tissue Thicknesses

Facial approximations based on facial soft tissue depth measurement tables often utilize the arithmetic mean as a central tendency estimator. Stephan et al. (J Forensic Sci 2013;58:1439) suggest that the shorth and 75‐shormax statistics are better suited to describe the central tendency of non‐normal soft tissue depth data, while also accommodating normal distributions. The shorth, 75‐shormax, arithmetic mean, and other central tendency estimators were evaluated using a CT ‐derived facial soft tissue depth dataset. Differences between arithmetic mean and shorth mean for the tissue depths examined ranged from 0 mm to +2.3 mm (average 0.6 mm). Differences between the arithmetic mean plus one standard deviation (to approximate the same data points covered by the 75‐shormax) and 75‐shormax values ranged from ?0.8 mm to +0.7 mm (average 0.2 mm). The results of this research suggest that few practical differences exist across the central tendency point estimators for the evaluated soft tissue depth dataset.     

Female Perpetrated Dyadic Psychological Aggression Predicts Relapse in a Treatment Sample of Men with Substance Use Disorders

This study examined whether female-to-male (FTM) psychological aggression predicted men’s relapse of substance use disorder (SUD) 6 months following substance use treatment. Men diagnosed with either a substance abuse or dependence disorder who had recently begun an SUD treatment program participated in the study with their female relationship partners (N = 173). Logistic regression was used to examine the relationship between baseline FTM psychological aggression and SUD relapse when controlling for baseline demographic, dyadic, substance abuse- and treatment-related variables, as well as frequencies of other male- and female-perpetrated aggressive dyadic behaviors. Higher frequencies of severe, but not minor, forms of FTM psychological aggression uniquely predicted an increased risk of relapse at 6 months follow-up. These data add to the developing research program highlighting the negative sequelae of female-perpetrated psychological aggression and also provide an empirical basis for targeting specific dyadic behaviors in the context of SUD treatment and relapse prevention.     

Posttraumatic Stress Disorder Symptoms,Relationship Adjustment,and Relationship Aggression in a Sample of Female Flood Victims

This study tested a model examining the interrelationships among posttraumatic stress disorder (PTSD) symptoms, intimate relationship adjustment, and intimate relationship aggression in a sample of 205 adult female flood victims. At the bivariate level, higher PTSD symptoms were associated with higher physical and psychological aggression victimization, poorer relationship adjustment, and higher physical and psychological aggression perpetration. Results from structural equation modeling (SEM) analyses indicated that relationship aggression victimization influenced aggression perpetration directly, and in the case of physical aggression, indirectly through its relationship with PTSD symptoms and relationship adjustment. The influence of PTSD symptoms on physical aggression perpetration was fully explained by poorer relationship adjustment. These findings extend prior work from other traumatized populations documenting associations between variables reflecting PTSD symptomatology and indices of relationship functioning, and indicate a need for further investigation in this area of inquiry. This research was supported in part by a grant to Patricia A. Resick from the National Institute of Mental Health (1-R01-MH55542).     

Blast Suppression Foam,Aqueous Gel Blocks,and their Effect on Subsequent Analysis of Forensic Evidence*

In addition to having blast mitigation properties, aqueous foam concentrate AFC-380 blast suppression foam is designed to capture aerosolized chemical, biological, and radioactive particles during render-safe procedures of explosive devices. Exposure to aqueous environments and surfactants may negatively affect forensic evidence found at the scene, but the effects of AFC-380 foam and aqueous gel on the preservation and subsequent analysis of forensic evidence have not previously been investigated. Sebaceous finger and palm prints and DNA samples on paper, cardboard, tape, and various metal and plastic items, along with hairs, carpet and yarn fibers, and inks and documents, were exposed to AFC-380 foam. Similar mock evidence was also exposed to a superabsorbent gel of the type found in aqueous gel blocks used for shrapnel containment. Exposure to foam or aqueous gel was associated with a dilution effect for recovered DNA samples, but quality of the samples was not substantially affected. In contrast, exposure to AFC-380 foam or gel was detrimental to development of latent finger and palm prints on any substrate. Neither the hair nor the fiber samples were affected by exposure to either the foam or gel. Indented writing on the document samples was detrimentally affected by foam or gel exposure, but not inks and toners. The results from this study indicate that most types of forensic evidence recovered after being exposed to aqueous gel or blast suppression foam can be reliably analyzed, but latent finger and palm prints may be adversely affected.
