Full textAbstract:
The article opens by briefly reviewing studies of sexuality in and around organizations from the 1970s. These studies showed considerable theoretical, empirical and conceptual development, as in the concept of organization sexuality. Building on this, the article’s first task is to analyse alternative future scenarios for organization sexualities, by way of changing intersections of gender, sexuality and organizational forms. Possible gendered future scenarios are outlined based on, first, gender equality/inequality and, second, gender similarity/difference between women, men and further genders: hyper-patriarchy scenario—men and women becoming more divergent; with greater inequality; late capitalist gender scenario—genders becoming more convergent, with greater inequality; bi-polar scenario—men and women becoming more divergent, with greater equality; postgender scenario—genders becoming more convergent, with greater equality. Somewhat similar scenarios for organization sexualities are elaborated in terms of gender/sexual equality and inequality and sexual/gender similarity and difference: heteropatriarchies scenario—greater sexual/gender difference and greater sexual or sexual/gender inequality; late capitalist sexual scenario—greater sexual/gender similarity and greater sexual or gender/sexual inequality; sexual differentiation scenario—greater sexual/gender difference and greater sexual or sexual/gender equality; sexual blurring scenario—greater sexual/gender similarity and greater sexual or sexual/gender equality. The article’s second task is to addresses the impact of globalizations and transnationalizations, specifically information and communication technologies and other socio-technologies, for future scenarios of organization sexualities. The characteristic affordances of ICTs—technological control, virtual reproducibility, conditional communality, unfinished undecidability—are mapped onto the four scenarios above and the implications outlined.

Full textAbstract:
Gender is one of the central categories organizing children’s social world. Clear patterns of gender development have been well-documented among cisgender children (i.e., children who identify as a gender that is typically associated with their sex assigned at birth). We present a comprehensive study of gender development (e.g., gender identity and gender expression) in a cohort of 3- to 12-y-old transgender children (n = 317) who, in early childhood, are identifying and living as a gender different from their assigned sex. Four primary findings emerged. First, transgender children strongly identify as members of their current gender group and show gender-typed preferences and behaviors that are strongly associated with their current gender, not the gender typically associated with their sex assigned at birth. Second, transgender children’s gender identity (i.e., the gender they feel they are) and gender-typed preferences generally did not differ from 2 comparison groups: cisgender siblings (n = 189) and cisgender controls (n = 316). Third, transgender and cisgender children’s patterns of gender development showed coherence across measures. Finally, we observed minimal or no differences in gender identity or preferences as a function of how long transgender children had lived as their current gender. Our findings suggest that early sex assignment and parental rearing based on that sex assignment do not always define how a child identifies or expresses gender later.

Full textAbstract:
While the focus of most research in women's politics has been on the number of legislative seats and explaining the under-representation of women and other marginalized groups, we argue that there also needs to be a greater focus on voters themselves and their attitudes about gender representation in Indonesia. We focus on three broad series of questions. First, gender differences in attitudes about women candidates precisely. Second, gender differences in policy priorities. Third, gender differences in attitudes about one specific aspect of Indonesian elections – money politics or what is sometimes referred to as "vote-buying." The data are drawn from a stratified probability sample of citizens in the Demak and Pati regencies in Central Java, Indonesia. A total of 800 respondents were in the sample, including 55 percent of the sample consisted of women. The finding has some interesting implications in how to understand gender differences in Indonesian politics. Men and women both respond with the correct "rhetoric" view about the importance of women candidates and descriptive representation. Still, both genders shift from the "rhetoric" view to the "logic" view about policies that have a more direct impact on their own lives.

Full textAbstract:
AbstractSimilar peers are more likely to become friends, but it remains unclear how the combination of multiple characteristics, known as multidimensional similarity, influences friendships. This study aimed to investigate whether similarity in gender (attribute) and bullying or victimization (network position) contributes to friendships. The school-level networks of friendships and victim-bully relationships in 17 Dutch elementary schools (2,130 students) were examined using multiplex longitudinal social network models (RSiena). The results showed that friendships were more likely to occur between same-gender peers and between bullies sharing their targets of victimization. Multidimensional similarity (similarities in gender as well as bullying) increased the likelihood of friendships for same-gender bullies targeting the same victims, but not for same-gender victims sharing bullies. The findings underline the importance of unraveling the interplay between different dimensions of similarity for children’s relationships and surpass unidimensional similarity based on single attributes.

Full textAbstract:
Understanding dyadic personality configurations and their associations with marital quality helps identify couples who are at high risk of marital strain. However, current research on personality similarity among spouses usually confounds couples with similarly positive and similarly negative personalities. This study aimed to (1) provide a clearer classification of dyadic personality profiles among older couples, (2) examine the associations between these profiles and both partners’ marital quality, and (3) explore gender differences in these associations. Data came from 3,178 older couples drawn from the 2010/2012 waves of the Health and Retirement Study. Latent profile analysis was used to identify dyadic personality profiles based on spouses’ standardized Big Five personality scores. Multilevel models examined associations between dyadic personality profiles and each partner’s marital quality, testing for gender differences as well. Six dyadic personality profiles were identified, including two opposite profiles (52%; positive wife–negative husband and positive husband–negative wife), two similar profiles (40%; similarly positive and similarly negative), and two extreme profiles (8%; extremely negative husband and extremely negative wife). Couples in the similarly positive profile reported the best marital quality, whereas couples in the similarly negative profile and the two extreme profiles reported the worst marital quality. The associations between profiles characterized by negative traits and marital quality were more pronounced among wives than husbands. This study advances the understanding of personality similarity and its consequences, suggesting heterogeneous subgroups of dyadic personalities among older couples and providing evidence of gender differences in the implications of personality similarity for relationship quality.

Full textAbstract:
Technical advancements allow for embodied virtual agents to not only be increasingly human-like, but also to behave and look like particular individuals. As biases towards self-similarity have been found in human-human studies, it is of interest to explore to what extent this applies to virtual characters (VCs). This work set out to extend on previous research that has investigated the effects of facial self-similarity in VCs, and explore it in the context of empathic emotion. For this aim, a method for creating facially similar virtual characters was developed and a user study conducted where 13 participants were told autobiographical stories by a virtual character that either did or did not resemble them facially and/or in gender category. The participants' first impressions and emotional responses were measured. The results showed that even though similarity was not explicitly perceived, a bias might exist towards more positive impressions of self-similar characters, especially in terms of gender category. Regarding the emotional responses, the results did not allow for discovering any difference between conditions but pointed to some interesting differences in comparison to what was hypothesized. The immense ways in which the appearances of virtual characters can be altered provides possibilities to influence the interaction with them. However, although biases might exist on a general level, it is difficult to predict the human responses in individual cases. Virtual characters might make possible a more human-like interaction with technology, however, it might also mean that our reactions to them are influenced by more parameters and our relations to them become even more like those with other humans: complex.Den tekniska utvecklingen möjliggör numera att virtuella agenter kan göras inte bara människolika, utan även lika specifika individer i hur de beter sig och ser ut. Då tidigare studier påvisat att människor ofta föredrar personer som i någon mån liknar dem själva, är det intressant att utforska i vilken utsträckning detta även gäller virtuella karaktärer. Detta arbete hade som mål att undersöka effekterna av visuella likheter mellan människor och virtuella karaktärer, med fokus på ansikten och genus och i en kontext där empati är betydande. En metod för att konstruera virtuella karaktärer som hade visuella likheter med specifika användare utvecklades, och en användarstudie med 13 deltagare genomfördes. I det konstruerade scenariot berättade en karaktär, som hade likheter med användaren antingen gällande ansiktets utseende och/eller genus, självbiografiska historier. Intrycket av karaktären och den emotionella responsen mättes. Resultaten visade att den visuella likheten inte uppfattades explicit. Dock fanns tendenser som pekar på att likheter framför allt när det gäller sociala kategorier som genus, kan ha en positiv påverkan på hur virtuella karaktärer uppfattas. Det gick inte att upptäcka några skillnader mellan betingelserna gällande den emotionella responsen, men resultaten påvisade intressanta avvikelser från de förväntade reaktionerna. Möjligheterna att designa och anpassa virtuella karaktärer till olika individer och situationer ökar, vilket kan utnyttjas för att försöka påverka hur människor förhåller sig till och interagerar med dem. Det är dock svårt att förutsäga hur människor kommer att reagera och relatera till en virtuell karaktär utifrån generella tendenser, vilket denna studie visar. Virtuella karaktärer kan möjliggöra en mer människolik interaktion med teknik, men det innebär också att många parametrar är inblandade och att relationerna med tekniken blir liksom relationerna mellan människor: komplexa.

Mezzenzana, Francesca. "Living through forms : similarity, knowledge and gender among the Pastaza Runa (Ecuadorian Amazon)." Thesis, London School of Economics and Political Science (University of London), 2015. http://etheses.lse.ac.uk/3181/.
Full textAbstract:
In this thesis I explore the knowledge practices of the Pastaza Runa, an indigenous group of the Ecuadorian Amazon. A central claim in my work is that processes of knowledge acquisition among the Runa involve an acknowledgement that human bodies, as well as non-human ones, share a network of ‘likeness’. This is not to be located specifically in the possession of a soul nor in the ‘shared’ substance of the body. For the Runa, humans share with non-humans specific ‘patterns’ of action, which I call ‘forms’. Things can affect humans (and vice versa) because they share a certain formal resemblance. Such resemblance is not found in discrete entities, but rather in the movements between entities. As such, forms cannot be reduced to the physicality of a singular body: they are subject-less and inherently dynamic. The concept of forms developed in this thesis seeks to think about the relationship between human and objects in ways which go beyond ideas of ensoulment or subjectification. Such focus is central to my analysis of the relationship between humans and objects, and, in particular, between women and their ceramic pots. I explore the connection between women and pots by following closely the sequences of elaboration of ceramic vessels. Pottery making is intimately linked to women’s capacity for engendering novelty. I suggest that, for the Runa, the differentiation between women and men is not ‘made’ but rather given a priori. The ‘givenness’ of this difference has major implications for what one - as a Runa woman or man - can know or do. Thus, I explore how women, by virtue of their capacity for giving birth, are thought to be ‘inherently’ inclined towards ‘exteriority’. By virtue of such ‘outward’ propensity, women need to engage in processes of making knowledge visible to the eyes of others. This ‘exteriorizing’ process has important consequences for the ways men and women are respectively thought to become ‘acculturated’. Ultimately this work also aims to examine how processes of ‘change’ - a key concept in Amazonian cosmologies - are inevitably gender inflected.

Full textAbstract:
Role models can serve as a means to counteract the prevalent 'Think Leader, Think Male' stereotype. This study was designed to assess the impact of role model similarity on women's leadership self-efficacy, task performance and future leadership behavior, using two conceptualizations of similarity – match with leadership self-concept and attainability of the role model. Additionally, the process by which one's self-perceptions of leadership impact judgments of one's own behavior was also investigated. Participants were presented with a role model vignette in a laboratory setting, following which they complete a leadership task. Results indicated that there were no significant effects of the interaction of the two role model manipulations of various leadership outcomes. However, match of role model with one's self-concept did impact one's leadership self-efficacy. Results also indicated that agentic leader prototypes partially mediated the relation between individuals' self-concept and self-judgments, such that participants whose self-concept matched the role model activated the agentic leader prototype. Overall findings suggest that match with one's self concept plays an important role in role models being perceived as similar to the self, which can have important implications for women's leadership development.Master of Science

Full textAbstract:
Research investigating the underlying causes and factors involved in violence and aggression has suggested there is a tendency for aggression to escalate as a means to justify prior aggression. In addition, past research has also examined the effect of perceived similarity towards the target of aggression on intensity and escalation of aggression. This study looked at the relationship between initial level of aggression and the escalation of aggression and at perceived similarity to the target of aggression as a possible factor influencing this escalation. Individuals engaging in severe initial aggression who experience higher perceived similarity to their targets of aggression should be more prone to justifying their actions and so might escalate more. To examine this, subjects could administer any of 10 levels of negative reinforcement (insults) to a learner for incorrect responses. Half of the subjects were required to practice this procedure with a mild and half with a severe insult. Results indicated that an effect of perceived similarity emerged, with individuals using less severe insults when perceived similarity to the learner was high. Contrary to predictions, high-perceived similarity to the learner stemmed escalation for participants insulting the learner with a severe insult initially. Moreover, participants who insulted with a mild insult initially escalated in their aggression when perceived similarity was high. In addition, an interaction effect of gender and perceived similarity was found, with men engaging in more severe subsequent aggression than women when perceived similarity to the target of aggression is high. The limitations, further directions, and implications of this study are discussed.

Full textAbstract:
The aim of this essay is to examine the differences in language use between the genders in game reviews, to find whether there are differences in the use of the language depending on gender. Both sexist language and technical aspects are examined, the technical aspects of writing have been chosen from previous research about gendered differences in writing. The reviews are randomly chosen but the games are selected. There is an equal amount of games with male and female main characters, and the number of reviews is chosen according to the number of reviews written by females, as there are fewer of them, and thus easier to find a matching number of reviews written by males rather than vice versa. The reviews are then examined to find sexist language and differences. This essay finds that there is sexist language in the writing of both genders, such as marked language, but only when the main character of the game is female. Both genders tend to focus on the appearance of female characters and the characteristics of male characters, but there is no known previous research about male and female game characters to compare these results to. However, the technical differences remain consistent with previous research on the same subject, such as female reviewers using more pronouns than male reviewers, and male reviewers using fewer verbs than female reviewers.

Upplevd likhet med målpersonen har ansetts vara viktig för empati och viss forskning har visat att empatin ökar med upplevd etnisk sam-hörighet. Denna studies primära syfte var att experimentellt undersöka om svenska och icke-svenska deltagare kände olika mycket empati beroende på målpersonens etnicitet samt upplevd likhet med mål-personen. Majoriteten av de 160 deltagarna rekryterades från Mälar-dalens högskola, varav 102 var svenska och 84 var kvinnliga. Resultatet visade två signifikanta disordinala interaktioner där svenska deltagare kände signifikant mer empati och upplevd likhet med en svensk än icke-svensk målperson, medan icke-svenska inte visade signifikant mer empati eller upplevd likhet med en icke-svensk än svensk målperson. Ingen signifikant skillnad i empati fanns mellan äldre och yngre deltagare. Män uppvisade signifikant lägre empati än kvinnor och inget av könen väckte mer empati. Orsaken till de disordinala interaktionerna diskuterades i termer av social kategorisering. Vidare forskning med en annan definition av begreppet etnicitet föreslogs.

Full textAbstract:
This doctoral study focuses on upward influence tactics and the social exchange process which takes place between leaders and their followers. The research posits Leader-Member Exchange (LMX) dimensions as a theoretical mechanism for understanding how upward influence tactics work. More specifically, it analyses the roles of LMX dimensions in mediating the relationship between followers’ upward influence tactics and job performance ratings. Furthermore, it seeks to understand the role of gender similarity in moderating the relationship between upward influence tactics and LMX dimensions. It goes on to query upward influence tactics’ direct and non-linear relationships with job performance ratings, the differences between leaders’ and followers’ reporting of the use of follower upward influence tactics and test their relationships with job performance ratings, and the use of these tactics in the Saudi context. The empirical research for the present study took place in public, private, and non-profit organizations in Saudi Arabia. This is a country which has not been the focus of research on influence tactics to date in the literature. Based on a sample of 389 leader-follower pairs, the results show a number of significant relationships. Results revealed that rationality and self-presentation tactics have positive relationships with job performance ratings while exchange of benefits and upward appeal tactics have negative relationships with job performance ratings. Moreover, LMX-loyalty mediates the relationship between upward influence tactics of rationality, ingratiation, upward appeal, coalition, and self-presentation with job performance ratings. LMX-affect mediates the relationship between upward influence tactics of upward appeal and coalition with job performance ratings. Gender similarity moderates the relationship between rationality ingratiation, upward appeal, coalition, and self-presentation tactics and LMX-loyalty. Specifically, the relationship between these tactics and job performance ratings are mediated by LMX-loyalty in case of the leader and the follower having the same gender. Additionally, non-linear relationships have been found between the use of coalition and upward appeal tactics and job performance ratings within Saudi culture. These latter findings suggesting non-linear effects for some upward influence tactics propose new avenues for conducting research in the area of influence tactics within differing cultural contexts. Finally, while rational persuasion and ingratiation were the most-used tactics, self-presentation was moderately used in Saudi culture. Assertiveness, upward appeal, coalition, and exchange of benefits were used far less by comparison in Saudi Arabian culture.

Full textAbstract:
This paper analyses the gender earnings gap in Sweden at career entry, for individuals with comparable educational profile. There are many studies on this topic. Usually, researchers are focusing their attention on the evolution of this gap through individuals’ career. Our paper concentrates only on individual’s career entry, to exclude work experience as an explanatory factor. By studying six different educational fields we can have a precise image of the use of human ressources in the economy.An empirical analysis has been conducted using the method of OLS on a restricted data sample concerning graduates, having accomplished at least two years of university education. The result showed that, even at career entry, the raw gender earnings gap is of 20,2%. After controlling for fields of studies and occupations, the gap is reduced to 15,4%. This gap fluctuates among different fields of education, depending on the society’s perception of these fields. We distinguish male-dominated (i.e. Engineering and manufacturing), female-dominated (i.e. Teaching methods and teacher education) and gender-neutral (i.e. Social sciences, law, commerce and administration) educational fields. Our results depict some large gender earnings gap within male-dominated fields of study – women earn on average 20% less than their male counterparts when studying Engineering and manufacturing – and rather small ones within female-dominated and gender-neutral fields of study but due to statistical insignificance of the gender dummy coefficients we cannot make a conclusion concerning these fields.

The plants release primary and secondary metabolites in the environment that may influence the development of adjacent vegetation, this interference phenomenon is called allelopathy. It is recognized as an important ecological process because it interferes with the structure, distribution, composition and dynamics of plant communities. Studies on allelopathic interactions may be useful in the search for natural phytotoxins are produced by plants or microorganisms to be used as natural herbicides, more specific and less harmful to the environment. According to floristic survey conducted by IBGE, Myrtaceae family is one of the major in the cerrado ecosystem. This study attempted to clarify the following issues: species of Myrtaceae family present in the cerrado (Brazilian savanna) exhibit allelopathic potential? There is a similar allelopathic response within genera? Among the active species, which is most promising for starting a bioprospecting? Some of these species has potential as a herbicide for use in agroforestry or organic production of food? To answer these questions were conducted experiments of seed germination and seedling growth of target species cultivated and weedy, and chemical extraction of active compounds in leaves of Myrcia tomentosa. The leaves of Blepharocalyx salicifolius, Campomanesia pubescens, Eugenia bimarginata, Eugenia klotzschiana, Eugenia myrcianthes, Eugenia punicifolia, Myrcia bella, Myrcia lingua, Myrcia multiflora, Myrcia splendens, Myrcia tomentosa, Psidium australe, Psidium cinereum, Psidium laruotteanum and Psidium rufum were collected , cleaned, crushed and stored in plastic bags until use. In the first stage, were carried out the germination and growth bioassays using aqueous extracts of leaf in a concentration of 10% (w / v). We selected three target species, Lactuca sativa and Solanum lycopersicum, both eudicotyledonous and a monocotyledonous Allium cepa. The extracts were applied to all Myrtaceae species compared with the control (distilled water). In the second phase, bioassays were carried out using aqueous extracts of leaves at concentrations of 5 and 10% (w / v). We selected as target species three weeds Euphorbia heterophylla, Echinochloa crus-galli and Ipomoea grandifolia. The leaf extracts of B. salicifolius, M. multiflora, M. splendens and M. tomentosa were compared to negative control (distilled water) and positive (herbicide Oxyfluorfen). In the third stage were carried out biotests germination, growth, and coleoptile of wheat (Triticum aestivum) to direct chemical extraction of active compounds of M. tomentosa. The extractions were carried out using dried leaves powdered and organic solvents of different polarity, the extracts were fractionated using chromatographic column and purified by HPLC. The isolated and purified compounds were identified in RMN13C and RMN1H, by comparison of spectra. The results showed that aqueous extracts of twelve out of fifteen donor species evaluated showed allelopathic activity and each species showed a distinct behavior regarding the allelopathic activity, no grouping by taxonomic proximity. Evaluating the four species most active on weeds species, was detected the potential and efficiency of the extracts, since these were more toxic to weeds species than the herbicide. The leaf extracts of M. tomentosa stood out for demonstrating high activity even at low concentrations, so was chemical extraction from powdered of leaves of M. tomentosa were isolated two compounds from the ethyl acetate extract: juglanin and avicularin, the difference between ix both is the presence of one hydroxyl attached to carbon 3' in avicularin molecule, this difference has an phytotoxic effect more pronounced in the juglanin. This paper is the first report of the presence of the flavonoids kaempferol (juglanin) and quercetin (avicularin) in species of Myrtaceae of cerrado (Brazilian savanna) and gave foundation for future studies on bioprospecting of the M. tomentosa, which did not find any reports of allelopathic studies, fractionation and identification of chemical compounds.
Os vegetais liberam metabolitos primarios e secundarios no ambiente que podem influenciar no desenvolvimento da vegetacao adjacente, este fenomeno de interferencia e denominado alelopatia. E reconhecida como um processo ecologico importante, pois interfere na estrutura, distribuicao, composicao e dinamica de comunidades vegetais. Estudos sobre interacoes alelopaticas podem ser uteis na busca por fitotoxinas naturais, produzidas por plantas ou microrganismos a serem empregados como herbicidas naturais, mais especificos e menos prejudiciais ao ambiente. De acordo com inventario floristico realizado pelo IBGE a familia Myrtaceae e uma das principais em riqueza e diversidade no ecossistema de cerrado. Assim, este trabalho tentou esclarecer as seguintes questoes: especies da familia Myrtaceae presentes no cerrado apresentam potencial alelopatico? Existe semelhanca na resposta alelopatica dentro dos generos? Dentre as especies ativas, qual a mais promissora para se iniciar uma bioprospeccao? Alguma dessas especies apresenta potencial para utilizacao como herbicida em sistemas agroflorestais ou de producao organica de alimentos? Para responder essas perguntas foram realizados bioensaios de germinacao de diasporos e crescimento de plantulas, de especies alvo cultivadas e infestantes de cultura, e extracao quimica de compostos ativos em folhas de Myrcia tomentosa. As folhas maduras de Blepharocalyx salicifolius, Campomanesia pubescens, Eugenia bimarginata, Eugenia klotzschiana, Eugenia myrcianthes, Eugenia punicifolia, Myrcia bella, Myrcia lingua, Myrcia multiflora, Myrcia splendens, Myrcia tomentosa, Psidium australe, Psidium cinereum, Psidium laruotteanum e Psidium rufum foram coletadas, higienizadas, trituradas e armazenadas em embalagens plasticas ate a utilizacao. Na primeira etapa, os bioensaios de germinacao e crescimento, foram efetuados utilizando-se extratos aquosos de po de folhas em concentracao de 10% (p/v). Como especies receptoras foram selecionadas duas eudicotiledoneas Lactuca sativa e Solanum lycopersicum e, uma monocotiledonea Allium cepa, nas quais foram aplicados os extratos de todas as especies de Myrtaceae comparadas ao controle (agua destilada). Na segunda etapa, os bioensaios foram efetuados utilizando-se extratos aquosos de po de folhas em concentracao de 5 e 10% (p/v). Como especies receptoras foram selecionadas as infestantes de cultura Euphorbia heterophylla, Echinochloa crus-galli e Ipomoea grandifolia, nas quais foram aplicados os extratos de folhas de B. salicifolius, M. multiflora, M. splendens e M. tomentosa, comparadas ao controle negativo (agua destilada) e ao positivo (herbicida Oxifluorfem). Na terceira etapa, foram efetuados biotestes de germinacao, crescimento e de coleoptilo de trigo para direcionar a extracao quimica de compostos ativos de M. tomentosa. Para tanto as extracoes foram feitas empregando-se o po de folhas e os solventes organicos de diferentes polaridades. Os extratos foram fracionados em coluna cromatografica e purificados em CLAE. Os compostos isolados e purificados foram identificados em RMN13C e RMN1H, por comparacao de espectros. Os resultados mostraram que extratos aquosos de doze das quinze especies doadoras avaliadas apresentaram atividade alelopatica e cada especie demonstrou comportamento distinto em relacao a atividade alelopatica, nao houve agrupamento por proximidade taxonomica. Avaliando as quatro especies mais ativas sobre especies invasoras, constatou-se o potencial e a eficiencia dos extratos, uma vez que estes foram mais fitotoxicos as especies invasoras que o herbicida. O extrato foliar de M. tomentosa destacou-se por demonstrar elevada atividade mesmo em baixa concentracao, assim foi realizada a extracao quimica do po folhas desta especie. Foram isolados dois compostos do extrato acetato de etila: juglanina e avicularina, o que as diferencia e a hidroxila ligada ao carbono 3 na molecula de avicularina, esta diferenca produziu efeito fitotoxico mais acentuado da molecula de vii juglanina. O presente trabalho relatou pela primeira vez a presenca dos flavonoides kaempferol (juglanina) e quercetina (avicularina) em uma especie de Myrtaceae do cerrado e deu embasamento para futuros estudos relativos a bioprospeccao da especie Myrcia tomentosa, da qual nao se encontrou nenhum relato de estudos alelopaticos, fracionamento e identificacao de compostos quimicos.

This chapter explores the relevance of social cues for voting behavior in Germany. It explores effects of social cues that build on role-based and social-similarity-based stereotyping. Using data from voter surveys that are merged with information about candidate characteristics, the analysis demonstrates that role-based cues played no part in affecting voter decisions on the first vote in the 2009 and 2013 German federal elections. By contrast, cues that build on social similarity (e.g. gender, age, education, social class, religion, or migrant background) appear to have made a difference, at least in certain subsections of the electorate, such as partisan independents.

Full textAbstract:
This book documents ways in which women’s performance practices engage with and localize world religions while creating opportunities for women’s agency. This study draws on the rich resources of three disciplines: ethnomusicology, gendered studies of religion, and religious music studies. It is a meta-ethnography formed by comparisons among different ethnographic case studies. The book analyses women’s performances at religious events in cultural settings spread across the world to demonstrate the pivotal roles women can play in localizing the practice of world religions, exploring moments in which performance allows women the agency to move, however momentarily, beyond culturally determined boundaries while revealing patterns that suggest unsuspected similarities in widely divergent religious contexts. With the rise of religious fundamentalism and with world politics embroiled in debate about women’s bodies and their comportment in public, ethnomusicologists and other scholars must address questions of religion, gender, and their intersection. By reading deeply into, but also across, the ethnographic detail of multiple studies, this book reveals patterns of similarity between unrelated cultures. It invites ethnomusicologists back into comparative work, offering them encouragement to think across disciplinary boundaries and suggesting that they can actively work to counter the divisive rhetoric of religious exceptionalism by revealing the many ways in which religions and cultures are similar to one another.

Full textAbstract:
Informed by practices of women’s activism in India, this book proposes a feminist social justice framework to address the wide range of issues women face globally, including economic exploitation; sexist oppression; racial, ethnic, and caste oppression; and cultural imperialism. The feminist social justice framework provides an alternative to mainstream philosophical frameworks that analyze and promote gender justice globally: universal human rights, economic projects such as microfinance, and cosmopolitanism. These frameworks share a commitment to individualism and abstract universalism that underlie certain liberal and neoliberal approaches to justice. Arguing that these frameworks emphasize individualism over interdependence, similarity over diversity, and individual success over collective capacity, McLaren draws on the work of Rabindranath Tagore to develop the concept of relational cosmopolitanism. Relational cosmopolitanism prioritizes our connections, while acknowledging power differences. Extending Iris Young’s theory of political responsibility, McLaren shows how Fair Trade connects to the economic solidarity movement. The Self-Employed Women’s Association and MarketPlace India empower women through access to livelihoods as well as fostering leadership capabilities that allow them to challenge structural injustice through political and social activism. Their struggles to resist economic exploitation and gender oppression through collective action show the importance of challenging individualist approaches to achieving gender justice. The book concludes with a call for a shift in our thinking and practice toward reimagining the possibilities for justice from a relational framework, from independence to interdependence, from identity to intersectionality, and from interest to sociopolitical imagination.

Full textAbstract:
This chapter discusses the claim that radical right parties are typically led and supported by men, and explores various aspects of gender bias as they relate to radical right parties and support for these parties. The first section considers the so-called gender gap in radical right voting, with women being significantly underrepresented among the radical right electorate compared with men. The second section examines how explanations for radical right voting behavior may differ between women and men. Whereas the majority of the research on radical right voting has taken for granted that women and men behave similarly, it shows that the limited available research does indicate some gender differences in the explanations for supporting a radical right party. The final section outlines some ideas for further research and the challenges that lie ahead for scholarship on gender and the radical right.

Full textAbstract:
This is the first data chapter. In this chapter, respondents who are described as true believers in the gender structure, and essentialist gender differences are introduced and their interviews analyzed. They are true believers because, at the macro level, they believe in a gender ideology where women and men should be different and accept rules and requirements that enforce gender differentiation and even sex segregation in social life. In addition, at the interactional level, these Millennials report having been shaped by their parent’s traditional expectations and they similarly feel justified to impose gendered expectations on those in their own social networks. At the individual level, they have internalized masculinity or femininity, and embody it in how they present themselves to the world. They try hard to “do gender” traditionally.

Full textAbstract:
In much research on gender and representation, the constraining factors for women’s political representation have served as a backdrop against which women’s activities are contextualized, rather than as a primary focus of research. Research explicitly focusing on men’s overrepresentation in politics does the opposite: it puts the reproduction of male dominance at the center of the analysis. Such a focus on men and masculinities and their relation to political power requires a set of analytical tools that are partly distinctly different from the tools used to analyze women’s underrepresentation. A feminist institutionalist framework is used to identify the logic of recruitment underpinning the reproduction of male dominance. It proposes and elaborates on two main types of political capital that under certain circumstances may reinforce male dominance and resist challenges to it: homosocial capital, consisting of instrumental and expressive rules favoring different types of similarity; and male capital, consisting of sexist and patriarchal resources that always favor men. Although the different types of political capital may be empirically related, they should be analytically separated because they require different methodological approaches and call for different strategies for change.

This chapter examines how contemporary globalization has created gendered labor by drawing on the experiences of Nepali immigrant women within pan-ethnic informal labor markets in Boston and New York City. After a brief overview of the existing theoretical framework, the chapter presents data on Nepali women's experiences in the informal economy. It shows how the economic opportunities available to these women are shaped by within-ethnic-group social location—Nepali Americans' social location in relation to wealthier Indian Americans (and their religious and linguistic similarity to this group). It also considers how some Nepali women, especially those who worked in the formal sector in Nepal, have begun to “bank” their social capital in their home countries. The Nepali women's experiences highlight the segmentation of the informal labor market for care work and suggest that, while they send remittances back to their home countries, some of this money is sent to nonfamily members.

Full textAbstract:
Catherine Reyes-Housholder and Gwynn Thomas highlight the unexpected emergence of female presidents and presidential candidates in Latin American politics. They point out that theories explaining the election of female executives globally fail to account for the rise of female presidents in Latin America and argue that the transition to democracy, women’s increasing political experience, the rise of the left, and recent political party crises have provided new opportunities for women in the presidency. However, female presidents must continually manage gendered expectations created from men’s past dominance of presidential power. While they appear similarly as successful governing as male presidents, only Michelle Bachelet has made gender equality a central component of her agenda. Female presidents have not used their constitutional powers to enact many gender equality policies, but in certain circumstances, they have been more likely than men to appoint women to their cabinets. Female presidents also have had some positive consequences for women’s participation in politics.

AbstractThis chapter addresses the systemic precarisation of individuals through the examination of Holy Orders (2013), the sixth title in Benjamin Black’s “Quirke series”. This crime novel describes the multi-layered precarity of Ireland’s travellers, that appear, I argue, as archives of the failing of infrastructural norms and paradigms of pathogenic vulnerability. Similarly, the story captures the corrupted network of control and influence sustained by the Catholic Church and its concomitant rule of silence, whose dysfunctionality generates a string of parallel justice. In my analysis, I will first explore how the failure of Ireland’s network of infrastructural support has prevailed throughout time, decimating the lives of some of its most vulnerable individuals. Then, I will trace the vigilantism that, as a convention in crime fiction, appears as a product of such deficiency and the troubling questions posed for the contemporary reader.

Abstract The goal of phylogenetics is to construct relationships that are true representations of the evolutionary history of a group of organisms or genes. The history inferred from phylogenetic analysis is usually depicted as branching in tree-like diagrams or networks. In nematology, phylogenetic studies have been applied to resolve a wide range of questions dealing with improving classifications and testing evolution processes, such as co-evolution, biogeography and many others. There are several main steps involved in a phylogenetic study: (i) selection of ingroup and outgroup taxa for a study; (ii) selection of one or several gene fragments for a study; (iii) sample collection, obtaining PCR products and sequencing of gene fragments; (iv) visualization, editing raw sequence data and sequence assembling; (v) search for sequence similarity in a public database; (vi) making and editing multiple alignment of sequences; (vii) selecting appropriate DNA model for a dataset; (viii) phylogenetic reconstruction using minimum evolution, maximum parsimony, maximum likelihood and Bayesian inference; (ix) visualization of tree files and preparation of tree for a publication; and (x) sequence submission to a public database. Molecular phylogenetic study requires particularly careful planning because it is usually relatively expensive in terms of the cost in reagents and time.

Abstract With visual similarity products can be assigned to a brand. The brand assignment based on shapes has only examined the contours (orientation, proportion and position) of selected elements so far. This paper investigates whether brand affiliation is also related to different surface types (curved and angular). For the investigation the vehicle front was selected. Distinguishable contours and surfaces were selected according to their semantic effect (friendliness, aggressiveness and perceived gender). The contours of the headlights and the lower air intake were determined based on anthropometric investigations (smiling and frowning faces) and were selected to be neutral to existing brands. Comparable semantic effects were found for curved and angular surfaces. Self-made vehicle fronts were designed with these parameters. An online survey was conducted with 150 users. First of all, the effects of the stimulus patterns generated for the factors contour (face) and surface were confirmed in the survey. Then the stimulus patterns were evaluated in pairs regarding their brand affiliation. The results show that brand affiliation can be implemented with contours and surfaces. Furthermore, it was determined that there are two user groups which differ in the evaluation of the brand affiliation.

Full textAbstract:
The problem of graph similarity measurement is fundamental in both complex networks and bioinformatics researches. Gene regulatory networks (GRNs) describe the interactions between the molecules in organisms, and are widely studied in the fields of medical AI. By measuring the similarity between GRNs, significant information can be obtained to assist the applications like gene functions prediction, drug development and medical diagnosis. Most of the existing similarity measurements have been focusing on the graph isomorphisms and are usually NP-hard problems. Thus, they are not suitable for applications in biology and clinical research due to the complexity and large-scale features of real-world GRNs. In this paper, a fast similarity measurement method called FSM for GRNs is proposed. Unlike the conventional measurements, it pays more attention to the differences between those influential genes. For the convenience and reliability, a new index defined as influence power is adopted to describe the influential genes which have greater position in a GRN. FSM was applied in nine datasets of various scales and is compared with state-of-art methods. The results demonstrated that it ran significantly faster than other methods without sacrificing measurement performance.

Full textAbstract:
It has recently been shown that the similarity between coagulation factors IX, X and protein C in the protein sequence is also evident in the organization of their genes. To further elucidate the relation of protein S to the other vitamin K-dependent clotting factors, we are now characterizing the human protein S gene. The size of the gene was estimated to be more than 45 kb, by hybridization of a cDNA for human protein S with chromosomal DNA in a Southern blot.We have isolated three overlapping clones from a human genomic DNA library in bacteriophage λ Charon 4A, which cover approximately 40 kb of the gene. The clones have been mapped by single- and double restriction enzyme digestion. Genomic subclones in pUC 18 which hybridize with cDNA probes for protein S have been isolated and sequenced to establish the intron/exon structure of the gene. The 5’- part of the human protein S gene closely resembles the corresponding part of the genes for factors IX, X and protein C. However, the thrombin sensitive region (amino acids 46-75), which is unique for protein S among the vitamin K-dependent clotting factors, is coded for by a separate exon. The 3'- end of the protein S gene, coding for amino acids 247-635, is not homologous to the catalytic region of the vitamin K-dependent serine proteases but shows a significant homology to human sex hormone binding globulin (SHBG).

Full textAbstract:
Generally, policymakers and tax analysts (as well as donors concerned about gender equity) have not made proper consideration about how tax policies and tax reforms can interact with gendered cultural norms in developing countries. However, there are worries that tax systems are biased against women and that recent tax reforms may increase the incidence of taxes on women and other underprivileged groups – while, at the same time, failing to garner sufficient tax revenue to fund social programmes necessary to enhance their lives. Since women in developing countries are particularly vulnerable to poverty, a comprehensive and rigorous assessment of tax systems (e.g., existing tax laws, tax administrations and new tax reforms) is needed to understand how they are uniquely affected. Gender-responsive tax programming by donors (and developing-country governments) requires dedication to assess the gender impact of tax policy and tax administration – i.e., who benefits and who is losing from existing tax arrangements or proposed reforms. Although there is growing evidence in the academic literature about the gender dimension of tax, there is still very limited programming by donors on tax policy and tax administration with an explicit focus on gender. Similarly, rarely do donor-funded programmes targeting gendered inequities and empowerment of women incorporate a clear tax agenda. However, there is some evidence that this trend is changing. Some recent regional and country programmes on DRM (e.g., on tax administration, tax policy, tax research, etc.), as well as business and investment climate improvement programmes, are incorporating explicit gender targets into their tax programme components. Some of these regional and country programmes are briefly discussed in the review (with more information on these provided in Sections 4 and 5).

Full textAbstract:
The objectives of this project were to develop the tools and methodologies for positional cloning of genes in tomato and apply them for the cloning a Fusarium resistance gene - I2.. The feasibility of positional cloning of disease resistance genes was demonstrated for Pto which confers resistance to pseudomonas (Martin et al. 1993). The Fusarium resistance gene was mapped genetically and physically and was found to be in close proximity to TG 105 (Segal et al. 1992). To obtain fine mapping of gene I2, and additional target genes in future projects, a high density linkage map was developed (Tanksley et al. 1992; Broun and Tanksley 1993). In addition two permanent mapping populations were constructed: a recombinant inbred (Paran et al. 1995; Zamir et al. 1993) and an introgression line population (Eshed et al. 1992; Eshed and Zamir 1994). Using these resources we determined that the I2 locus shows complete co-segregation, down to a resolution of a few Kb, with SL8 which shows architectural similarity with other plant resistance genes. Transformation and complementation analysis is in progress (Ori et al. in preparation).

Full textAbstract:
Meristems were the central issue of our project. Genes that are required for cell division, cell elongation, cell proliferation and cell fate were studied in the tomato system. The analysis of the dUTPase and threonine deaminase genes, along with the dissection of their regulatory regions is completed, while that of the RNR2 and PPO genes is at an advanced stage. All these genes were isolated in our laboratory. In addition, 8 different MADS box genes were studied in transgenic plants and their genetic relevances discovered. We have also shown that a given MADS box gene can modify the polarity of cell division without affecting the fate of the organ. In vivo interaction between two MADS box genes was demonstrated and the functional dependency of the tomato agamous gene on the TM5 gene product established. We have exploited the Knotted1 meristematic gene in conjunction with tomato leaf meristematic genes to show that simple and compound leaves and, for that matter, sepals and compound leaves, are formed by two different developmental programs. In this context we have also isolated and characterized the tomato Knotted1 gene (TKnl) and studied its expression pattern. A new program in which eight different meristematic genes in tomato will be studied emerged as a result of these studies. In essence, we have shown that it is possible to study and manipulate plant developmental systems using reverse genetic techniques and have provided a wealth of new molecular tools to interested colleagues working with tomato. Similarly, genes responsible for cell division, cell proliferation and cell fate were studied in Arabidopsis floral meristems. Among these genes are the TSO1, TSO2, HANABA TARANU and UNUSUAL FLORAL ORGANS genes, each affecting in its own way the number of pattern of cell divisions, and cell fate, in developing Arabodopsis flowers. In addition, new methods have been established for the assessment of the function of regulatory gene action in the different clonal layers of developing floral meristems.

Full textAbstract:
Genetic resistance is often the least expensive, most effective, and ecologically-sound method of disease control. It is becoming apparent that plant genomes contain large numbers of disease resistance genes. However, the numbers of different resistance specificities within a genepool and the genetic mechanisms generating diversity are poorly understood. Our objectives were to characterize diversity in clusters of resistance genes in wild progenitors of cultivated lettuce in Israel and California in comparison to diversity within cultivated lettuce, and to determine the extent of gene flow, recombination, and genetic instability in generating variation within clusters of resistance genes. Genetic diversity of resistance genes was analyzed in wild and cultivated germplasm using molecular markers derived from lettuce resistance gene sequences of the NBS-LRR type that mapped to the major cluster if resistance genes in lettuce (Sicard et al. 1999). Three molecular markers, one microsatellite marker and two SCAR markers that amplified LRR- encoding regions, were developed from sequences of resistance gene homologs at the Dm3 cluster (RGC2s) in lettuce. Variation for these markers was assessed in germplasm including 74 genotypes of cultivated lettuce, L. saliva and 71 accessions of the three wild Lactuca spp., L. serriola, L. saligna and L. virosa that represent the major species in the sexually accessible genepool for lettuce. Diversity was also studied within and between natural populations of L. serriola from Israel and California. Large numbers of haplotypes were detected indicating the presence of numerous resistance genes in wild species. We documented a variety of genetic events occurring at clusters of resistance genes for the second objective (Sicard et al., 1999; Woo el al., in prep; Kuang et al., in prepb). The diversity of resistance genes in haplotypes provided evidence for gene duplication and unequal crossing over during the evolution of this cluster of resistance genes. Comparison of nine resistance genes in cv. Diana identified 22 gene conversion and five intergenic recombinations. We cloned and sequenced a 700 bp region from the middle of RGC2 genes from six genotypes, two each from L. saliva, L. serriola, and L. saligna . We have identified over 60 unique RGC2 sequences. Phylogenetic analysis surprisingly demonstrated much greater similarity between than within genotypes. This led to the realization that resistance genes are evolving much slower than had previously been assumed and to a new model as to how resistance genes are evolving (Michelmore and Meyers, 1998). The genetic structure of L. serriola was studied using 319 AFLP markers (Kuang et al., in prepa). Forty-one populations from Turkey, Armenia, Israel, and California as well as seven European countries were examined. AFLP marker data showed that the Turkish and Armenian populations were the most polymorphic populations and the European populations were the least. The Davis, CA population, a recent post-Columbian colonization, showed medium genetic diversity and was genetically close to the Turkish populations. Our results suggest that Turkey - Armenia may be the center of origin and diversity of L. serriola and may therefore have the greatest diversity of resistance genes. Our characterization of the diversity of resistance genes and the genetic mechanisms generating it will allow informed exploration, in situ and ex situ conservation, and utilization of germplasm resources for disease control. The results of this project provide the basis for our future research work, which will lead to a detailed understanding of the evolution of resistance genes in plants.

Full textAbstract:
Crises exacerbate existing inequalities and vulnerabilities for marginalised people, including women and girls, children and youth, older people, people with disabilities, ethnic and religious minorities, and sexual and gender minorities. Many of them face multiple and intersecting inequalities, especially people who are forcibly displaced. Social assistance seeks to alleviate crisis impacts by protecting vulnerable people and averting them from deprivation, but the same structures and systems that make some people more exposed (and excluded) generally can exclude them from social assistance in crises and further undermine their situation. There is substantial literature that already discusses the benefits and opportunities of social assistance generally. The added value of this paper is in examining the risks of navigating access to social assistance in crises for these marginalised people, and the positive and negative outcomes of accessing or not accessing this assistance. The existing evidence suggests that social assistance can improve marginalised people’s food security, help households meet their basic needs, reduce stress and household tensions, reduce gender-based violence, improve health, education, and wellbeing, and reduce negative coping mechanisms. However, it can also disrupt their social support mechanisms and expose them to violence and further risks. Such risks – some of which also apply to those who are excluded from social assistance, and which do not apply to all marginalised people all the time similarly – include neglect, discrimination, sexual exploitation and abuse, increased household and community tensions, gender-based violence, stigma, theft, and accessibility issues.

Full textAbstract:
Intraspecies identification (DNA "fingerprinting") of pathogenic avian mycoplasmas is a powerful tool for epidemiological studies and monitoring strain identity. However the only widely method available for Mycoplasma gallisepticum (MG) and M. synoviae (MS)wasrandom amplified polymorphic DNA (RAPD). This project aimed to develop alternative and supplementary typing methods that will overcome the major constraints of RAPD, such as the need for isolation of the organism in pure culture and the lack of reproducibility intrinsic in the method. Our strategy focussed on recognition of molecular markers enabling identification of MG and MS vaccine strains and, by extension, pathogenic potential of field isolates. Our first aim was to develop PCR-based systems which will allow amplification of specific targeted genes directly from clinical material. For this purpose we evaluated the degree of intraspecies heterogeneity in genes encoding variable surface antigens uniquely found in MG all of which are putative pathogenicity factors. Phylogenic analysis of targeted sequences of selected genes (pvpA, gapA, mgc2, and lp) was employed to determine the relationship among MG strains.. This method, designated gene targeted sequencing (GTS), was successfully employed to identify strains and to establish epidemiologically-linked strain clusters. Diagnostic PCR tests were designed and validated for each of the target genes, allowing amplification of specific nucleotide sequences from clinical samples. An mgc2-PCR-RFLP test was designed for rapid differential diagnosis of MG vaccine strains in Israel. Addressing other project goals, we used transposon mutagenesis and in vivo and in vitro models for pathogenicity to correlated specific changes in target genes with biological properties that may impact the course of infection. An innovative method for specific detection and typing of MS strains was based on the hemagglutinin-encoding gene vlhA, uniquely found in this species. In parallel, we evaluated the application of amplified fragment length polymorphism (AFLP) in avian mycoplasmas. AFLP is a highly discriminatory method that scans the entire genome using infrequent restriction site PCR. As a first step the method was found to be highly correlated with other DNA typing methods for MG species and strain differentiation. The method is highly reproducible and relatively rapid, although it is necessary to isolate the strain to be tested. Both AFLP and GTS are readily to amenable to computer-assisted analysis of similarity and construction of a data-base resource. The availability of improved and diverse tools will help realize the full potential of molecular typing of avian mycoplasmas as an integral and essential part of mycoplasma control programs.

Full textAbstract:
The nascent work reviewed in this compendium indicates that married girls experience significant social isolation and limited autonomy. Across the studies examined, on indicators of mobility, exposure to media, and social networks, married girls are consistently disadvantaged compared to their unmarried peers. Similarly, across studies, on most of the domains explored here (mobility, decision-making, control over economic resources, and possibly gender-based violence), married girls tend to be less empowered and more isolated than slightly older married females. There may also be health issues associated with marriage during adolescence. Married girls are frequently at a disadvantage in terms of reproductive health information—particularly regarding STIs and HIV. First-time mothers, many of whom are adolescents, by virtue of their parity may have distinct maternal health needs and risks. Finally, early marriage potentially plays a role in exposing girls and young women to severe reproductive health risks, including HIV. Many of these elevated health risks may be largely, though not exclusively, derivative of their social vulnerability.

Full textAbstract:
Spore germination is a common and fundamental event in fungal development and in many instances an essential phase of fungal infection and dissemination. Spore germination is also critical for hyperparasites to function as biocontrol agents as well as in fermentation proceses. Our common objective is to understand the mechanisms which regulated spore germination and identify factors involved in pathogenicity related prepenetration development. Our approach is to exploit the overall similarity among filamentous fungi using both a plant pathogen (Colletotricum trifolii) and a model system that is genetically sophisticated (Neurospora crassa). The simulataneous use of two organisms has the advantage of the available tools in Neurospora to rapidly advance the functional analysis of genes involved in spore germination and development of an economically important fungal phytopathogen. Towards this we have isolated a protein kinase gene from C. trifolii (TB3) that is maximally expressed during the first hour of conidial germination and prior to any visible gene tube formation. Based on sequence similarities with other organisms, this gene is likely to be involved in the proliferative response in the fungus. In addition, TB3 was able to functionally complement a N. crassa mutant (COT-1). Pharmacological studies indicated the importance of calmodulin in both germination and appressorium differentiation. Using an antisense vector from N. crassa, direct inhibition of calmodulin results in prevention of differentiation as well as pathogenicity. Both cAMP dependent protein kinase (PKA) and protein kinase C (PKC) like genes have been cloned from C. trifolii. Biochemical inhibition of PKA prevents germination; biochemical inhibitors of PKC prevents appressorium differentiation. In order to analyze reversible phosphorylation as a regulatory mechanism, some ser.thr dephosphorylative events have also been analyzed. Type 2A and Type 2B (calcineurin) phosphatases have been identified and structurally and functionally analyzed in N. crassa during this project. Both phosphatases are essential for hyphal growth and maintenance of proper hyphal architecture. In addition, a first novel-type (PPT/PP5-like) ser/thr phosphatase has been identified in a filamentous fungus. The highly collaborative project has improved our understanding of a fundamental process in fungi, and has identified targets which can be used to develop new approaches for control of fungal plant pathogens as well as improve the performance of beneficial fungi in the field and in industry. In addition, the feasibility of molecular technology transfer in comparative mycology has been demonstrated.

Full textAbstract:
Date palm (Phoenix dactylifera L.) is the major fruit tree grown in arid areas in the Middle East and North Africa. In the last century, dates were introduced to new regions including the USA. Date palms are traditionally propagated through offshoots. Expansion of modern date palm groves led to the development of Tissue Culture propagation methods that generate a large number of homogenous plants, have no seasonal effect on plant source and provide tools to fight the expansion of date pests and diseases. The disadvantage of this procedure is the occurrence of off-type trees which differ from the original cultivar. In the present project we focused on two of the most common date palm off-types: (1) trees with reduced fruit setting, in which most of the flowers turn into three-carpel parthenocarpic fruits. In a severe form, multi-carpel flowers and fruitlets (with up to six or eight carpels instead of the normal three-carpel flowers) are also formed. (2) dwarf trees, having fewer and shorter leaves, very short trunk and are not bearing fruits at their expected age, compared to the normal trees. Similar off-types occur in other crop species propagated by tissue culture, like banana (mainly dwarf plants) or oil palm (with a common 'Mantled' phenotype with reduced fruit setting and occurrence of supernumerary carpels). Some off-types can only be detected several years after planting in the fields. Therefore, efficient methods for prevention of the generation of off-types, as well as methods for their detection and early removal, are required for date palms, as well as for other tissue culture propagated crops. This research is aimed at the understanding of the mechanisms by which off-types are generated, and developing markers for their early identification. Several molecular and genomic approaches were applied. Using Methylation Sensitive AFLP and bisulfite sequencing, we detected changes in DNA methylation patterns occurring in off-types. We isolated and compared the sequence and expression of candidate genes, genes related to vegetative growth and dwarfism and genes related to flower development. While no sequence variation were detected, changes in gene expression, associated with the severity of the "fruit set" phenotype were detected in two genes - PdDEF (Ortholog of rice SPW1, and AP3 B type MADS box gene), and PdDIF (a defensin gene, highly homologous to the oil palm gene EGAD). We applied transcriptomic analyses, using high throughput sequencing, to identify genes differentially expressed in the "palm heart" (the apical meristem and the region of embryonic leaves) of dwarf vs. normal trees. Among the differentially expressed genes we identified genes related to hormonal biosynthesis, perception and regulation, genes related to cell expansion, and genes related to DNA methylation. Using Representation Difference Analyses, we detected changes in the genomes of off-type trees, mainly chloroplast-derived sequences that were incorporated in the nuclear genome and sequences of transposable elements. Sequences previously identified as differing between normal and off-type trees of oil palms or banana, successfully identified variation among date palm off-types, suggesting that these represent highly labile regions of monocot genomes. The data indicate that the date palm genome, similarly to genomes of other monocot crops as oil palm and banana, is quite unstable when cells pass through a cycle of tissue culture and regeneration. Changes in DNA sequences, translocation of DNA fragments and alteration of methylation patterns occur. Consequently, patterns of gene expression are changed, resulting in abnormal phenotypes. The data can be useful for future development of tools for early identification of off-type as well as for better understanding the phenomenon of somaclonal variation during propagation in vitro.

Payne, Krista. Median Age at First Marriage, 2019. National Center for Family and Marriage Research, May 2021. http://dx.doi.org/10.25035/ncfmr/fp-21-12.
Full textAbstract:
The median age at first marriage in the United States has increased steadily since the mid-20th century. In the mid-1950s, the median age was at a record low of just over 20 for women and 22 for men, but by 2020, the median age was 28 for women and 30 for men (see Figure 1). The median age at first marriage has increased similarly for both men and women. Consequently, the gender gap in the median age at first marriage has persisted, fluctuating between 1.6 and 2.7 years. This profile uses data from the 2019 American Community Survey (ACS), 1-year estimates to track the trends in women’s and men’s median ages at first marriage. The ACS is ideal because it provides the best annual data on marital status and demographic characteristics allowing for direct estimation of the median age at first marriage (Simmons & Dye, 2004). This is an update to our previous profiles on the topic for the years 2017 (FP-19-06), 2014 (FP-16-07), 2013 (FP-15-05), 2010 (FP-12-07), and 2008 (FP-09-03).
