Covariation between reading and arithmetic skills from grade 1 to grade 7
2017
This study examined the extent to which reading and arithmetic skills show covariation at Grade 1 and at Grade 7, to what extent this covariation is time-invariant or time-specific, and to what extent different antecedents will predict these time-invariant and time-specific portions of the covariation. The reading and arithmetic skills of a total of 1335 Finnish children were assessed at the end of Grade 1 and then again at the end of Grade 7. Phonological awareness, letter knowledge, rapid automatized naming (RAN), counting, and parental education levels were measured in kindergarten; working memory at Grade 1 and nonverbal reasoning at Grade 3. The results showed that reading and arithmet…
Parenting Dimensions and Internalizing Difficulties in Italian and U.S. Emerging Adults: The Intervening Role of Autonomy and Relatedness
2015
The present study examined the associations between emerging adults’ perceived parental psychological control and autonomy support, and their autonomy, relatedness and internalizing difficulties in Italy and the U.S. The participants included 494 Italian and 414 U.S. college students, between 18 and 28 years of age (Mean = 21.58, SD = 2.18). Our findings showed that dependency-oriented psychological control had no significant direct associations with autonomy, relatedness or internalizing difficulties. Moreover, the association between parental autonomy support and internalizing problems was fully intervened by autonomy and relatedness, whereas the association between achievement-oriented p…
Parental Socialization and Its Impact across the Lifespan

Parenting Styles and Aggressive Adolescents: Relationships with Self-esteem and Personal Maladjustment
2019
ABSTRACT Current emergent studies are seriously questioning if parental strictness contributes to adolescent adjustment. This study examined whether the relationship between authoritative (warmth and strictness), authoritarian (strictness without warmth), indulgent (warmth without strictness), and neglectful (neither warmth nor strictness) parenting styles shows equal or different pattern of adjustment and maladjustment for aggressive and non-aggressive adolescents. The sample consisted of 969 Spanish adolescents, 554 females (57.2%) and 415 males, ranging from 12 to 17 years old. Families were classified into one of four typologies by their scores on warmth and strictness, and the adolesce…
Parental and Infant Gender Factors in Parent-Infant Interaction: State-Space Dynamic Analysis.
2017
This study aimed to investigate the influence of parental gender on their interaction with their infants, considering, as well, the role of the infant’s gender. The State Space Grid (SSG) method, a graphical tool based on the non-linear dynamic system (NDS) approach was used to analyze the interaction, in Free-Play setting, of 52 infants, aged 6 to 10 months, divided into two groups: half of the infants interacted with their fathers and half with their mothers. There were 50% boys in each group. MANOVA results showed no differential parenting of boys and girls. Additionally, mothers and fathers showed no differences in the Diversity of behavioral dyadic states nor in Predictability. However…
Data from: Harvesting changes mating behavior in European lobster
2018
Removing individuals from a wild population can affect the availability of prospective mates and the outcome of competitive interactions, with subsequent effects on mating patterns and sexual selection. Consequently, the rate of harvest-induced evolution is predicted to be strongly dependent on the strength and dynamics of sexual selection yet, there is limited empirical knowledge on the interplay between selective harvesting and the mating systems of exploited species. In this study, we used genetic parentage assignment to compare mating patterns of the highly valued and overexploited European lobster (Homarus gammarus) in a designated lobster reserve and nearby fished area in Southern Nor…
Data from: No evidence for prezygotic postcopulatory avoidance of kin despite high inbreeding depression
2018
Offspring resulting from mating among close relatives can suffer from impaired fitness through the expression of recessive alleles with deleterious effects. Post-copulatory sperm selection (a pre-zygotic mechanism of cryptic female choice) has been suggested to be an effective way to avoid inbreeding. To investigate whether post-copulatory female choice allows avoiding fertilization by close kin, we performed artificial inseminations in a promiscuous bird, the houbara bustard (Chlamydotis undulata undulata). Females were inseminated with a mix of sperm from triads of males, each constituted of a male genetically unrelated to the female, a first cousin, and a half-sibling. When counting the …
Data from: Aging parasites produce offspring with poor fitness prospects
2017
Senescing individuals have poor survival prospects and low fecundity. They can also produce offspring with reduced survival and reproductive success. We tested the effect of parental age on the performance of descendants in the nematode Heligmosomoides polygyrus, an intestinal parasite of rodents. We found that offspring of senescing worms had reduced within-host survival and reduced egg shedding over the first month post-infection compared with offspring produced by young parents. These results suggest that declining offspring quality is a component of senescence in parasitic nematodes and might have evolutionary consequences for the optimal schedule of age-dependent investment into reprod…
Parental informed consent in pediatric cancer trials: A population-based survey in Germany
2012
In Germany, nearly every child afflicted by a malignant dis-ease or a central nervous system tumor is enrolled in a clinicaltrial during treatment. Many of these children are under the age of5 years when they are first diagnosed [1]. The decision whether ornot to participate in a clinical trial is normally made by theparents on behalf of their child. Therefore, ensuring adequatelyinformed parental consent is essential to ethical practice in pedi-atric oncology.However, many empirical studies have revealed difficultieswith the informed consent process when parents are faced withthe decision to enroll their child in a clinical trial. Previous studyfindings have indicated that recalling signing th…
A study of hurdles in mass treatment of schistosomiasis in KwaZulu-Natal, South Africa
2015
Background: It has been estimated that 700 million people worldwide and 5.2 million people in South Africa are in need of annual treatment for schistosomiasis. In accordance with the current policy the Department of Health (DoH) in KwaZulu-Natal province, South Africa, aimed to reach 75% treatment coverage in a mass treatment campaign (MTC) of schools in a schistosomiasis-endemic area.Methods: A cross-sectional study was designed to explore the implementation, coverage, challenges and limitations of a DoH MTC in a middle-income country. The study was conducted by exploring nurses’ and research team records, school enrolment lists and parental consent forms.Results: Slightly more than 10 000…
