Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Sperm donor relations among adult offspring conceived via insemination by lesbian parents
Full text linkaim: the present study examined how adult offspring of lesbian parents relate to their anonymous, open-identity, or known donors. design: an online survey of 75 donor-conceived offspring of lesbian parents, aged 30-33 years, participating in Wave 7 of a U.S. 36-year longitudinal study of planned lesbian-parent families was conducted. offspring were asked about donor type, motivations for contacting the donor, terminology for the donor, relationship quality, means of relationship maintenance, impact of donor contact on offspring's other family members, and their feelings about the donor. results: twenty offspring with anonymous donors and 15 with open-identity donors whom they had not contacted felt comfortable not knowing their donors. Forty offspring knew their donors - anonymous, contacted through an online registry (n = 7), open-identity, contacted (n = 9), or known since childhood (n = 24). offspring who had contacted their donor since age 18 had their motivations fulfilled after contact, got along well with him, did not view him as a relative, and had told most family members about their contact, without detriment. whether the donor was unknown or known at this stage of their lives, most offspring were satisfied with their contact level. conclusion: this cohort of donor-conceived offspring of lesbian parents was among the first to reach adulthood during a time of technological advances in DNA testing, giving access to anonymous donors via online registries. the results inform donors, families, mental health providers, medical providers and public policymakers, on whether, how, and to what degree donor-conceived offspring optimally make donor contact
Helicopter parenting, emotional avoidant coping, mental health, and homophobic stigmatization among emerging adult offspring of lesbian parents.
No full texthelicopter parents are highly involved parents who hover over and around their child, applying developmentally inappropriate levels of control and tangible assistance. previous research with different-sex parent families indicates that helicopter parenting is particularly problematic in emerging adulthood as it may indirectly affect the offspring's mental health through their use of emotional avoidant coping. knowledge is lacking, however, on the antecedents and consequences of helicopter parenting in lesbian-parent families. the present longitudinal, questionnaire-based study investigated the effect of homophobic stigmatization in adolescence on mental health via helicopter parenting and emotional avoidant coping among 76 (37 females and 39 males) national longitudinal lesbian family study 25-year-old offspring of lesbian parents. all participants were cisgender, born in the USA, and conceived through donor sperm, with the majority being white, heterosexual, highly educated, and no longer living with their parents. parents who reported that their offspring experienced homophobic stigmatization in adolescence were likely to enact higher helicopter parenting in emerging adulthood. then, higher scores on helicopter parenting were associated with offspring's greater use of emotional avoidant coping, which in turn negatively affected the mental health of emerging adult offspring. discussed in light of bowen's family differentiation theory, the results suggest that clinicians should examine helicopter parenting in the context of lesbian parents' developmental history and potential tendency to project their own concerns about safety onto their child in order to reduce the distress of experienced homophobic stigmatization
Adult offspring of lesbian parents reflect on having been donor conceived: Feelings about their sperm donor and donor siblings
No full textthe U.S. national longitudinal lesbian family study is the longest prospective study of offspring conceived via donor insemination (DI), beginning in 1986 when DI became possible for lesbian women. the 75 offspring surveyed at Wave 7 were adults in their early thirties (M = 30.93, SD = 0.92; 49.33% female, 48.00% male and 2.66% gender nonbinary; 90.67% White, 9.33% people of color), well past the early stages of identity development in adolescence and emerging adulthood. this is the first qualitative study focusing on feelings about DI among established adult offspring of lesbian parents. offspring generally felt positive about their donor conception, realizing that it enabled them to be born into a loving family that very much wanted them. they were grateful that the technology existed to allow lesbian parents to have children in the 1980s. most agreed that their nontraditional conception had influenced their concept of family, and many indicated willingness to be a gamete donor themselves. offspring also described childhood challenges with feeling different, challenges with the donor or lack of medical information about him. about half had discovered that they had donor siblings. because the offspring knew of their DI from an early age, they did not perceive this information as a threat to their personal or family identity. as use of dI increases and donor offspring and their parents may seek therapy, clinicians should be trained to address donor anonymity issues, disclosure to children, parental/offspring concerns, and donor sibling concerns and recommend community resources as needed
Sexual Orientation and Gender Identity Among Donor-Conceived Offspring in the U.S. National Longitudinal Lesbian Family Study from Adolescence to Adulthood
Full text linkintroduction concerns about parents with minoritized sexual identities often focus on the belief that their children will be confused about their gender and report a non-heterosexual orientation compared to children reared by heterosexual parents. yet, few longitudinal studies exist. methods gender identity, gender expression, sexual orientation, and sexual experiences were examined in 75 U.S. donor-conceived offspring (39 assigned females at birth (AFAB) and 36 assigned males at birth (AMAB)) of lesbian parents, when the offspring had reached adulthood (ages 30-33). Additionally, 72 of these offspring (38 AFAB and 34 AMAB) had also completed surveys in adolescence (age 17, data collected 2004-2009) and emerging adulthood (age 25, data collected 2012-2017), which enabled us to examine the developmental pathways of their sexuality.
results All AMAB offspring and 94.7% of AFAB offspring who identified as cisgender during adolescence continued to do so during emerging adulthood and adulthood. over time, sexual orientation was more fluid than gender identity, and AFAB offspring were more fluid than AMAB offspring. specifically, considering those who reported the same (heterosexual/straight; lesbian, gay/homosexual; or bisexual+) sexual orientation from adolescence through emerging adulthood to adulthood, 63.9% were AFAB and 82.4% were AMAB. More than half of AFAB offspring and 80.6% of AMAB offspring identified as heterosexual in adulthood, and the vast majority had had sex with a non-transgender man (86.5%) and a non-transgender woman (93.6%), respectively, in the last 5 years.conclusions this is the only study that has followed the biological offspring of lesbian parents from birth to adulthood, prospectively and longitudinally. the results indicate that offspring of lesbian parents are less likely to identify as transgender than the general public, but more likely to identify as LGB or queer. policy Implications As gender and sexual identity development significantly impacts well-being, creating supportive environments for offspring of lesbian parents and increasing public awareness of the connections among developmental milestones, health, and thriving are vital
Adults Conceived via Donor Insemination by Lesbian Parents Reflect on Their Own Future Parenting Plans (and Their Own Parents Reflect on Being Grandparents)
No full textthe national longitudinal lesbian family study (NLLFS) started in 1986 when donor insemination became available for lesbian women in the U.S. wave 7 of the NLLFS was the first time that adults conceived via donor insemination were asked if they had or planned to have children, and what they anticipated telling children about their own nontraditional conception. Of 75 NLLFS adult offspring (mean age 30.93; 49.33% female, 48.00% male, and 2.66% gender nonbinary; 90.67% White, 9.33% people of color), 8 (10.67%) had children and 42 of the rest (62.67%) hoped to have children. Most anticipated no parenting challenges, though some mentioned societal reactions or not having had a father. they expected to rear children in an open-minded and child-focused way, and to discuss their own nontraditional conception in a casual and straightforward manner. they viewed their own mothers as role models. wave 7 was also the first time that NLLFS parents were asked about grandchildren; of 124 parents, 7 (5.64%) were grandparents. They expressed joy in spending time with their grandchildren and pride in their offspring's parenting skills. the results are discussed in relation to research about how parents who are members of minority groups educate children about minority status
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
