Genetic Analysis of Tolerance to Rice Tungro Bacilliform Virus in Rice (Oryza sativa L.) Through Agroinoculation

Balimau Putih [an Indonesian cultivar tolerant to rice tungro bacilliform virus (RTBV)] was crossed with IR64 (RTBV, susceptible variety) to produce the three filial generations F1, F2 and F3. Agroinoculation was used to introduce RTBV into the test plants. RTBV tolerance was based on the RTBV level in plants by analysis of coat protein using enzyme-linked immunosorbent assay. The level of RTBV in cv. Balimau Putih was significantly lower than that of IR64 and the susceptible control, Taichung Native 1. Mean RTBV levels of the F1, F2 and F3 populations were comparable with one another and with the average of the parents. Results indicate that there was no dominance and an additive gene action may control the expression of tolerance to RTBV. Tolerance based on the level of RTBV coat protein was highly heritable (0.67) as estimated using the mean values of F3 lines, suggesting that selection for tolerance to RTBV can be performed in the early selfing generations using the technique employed in this study. The RTBV level had a negative correlation with plant height, but positive relationship with disease index value

Caregiving experience and its influencing factors : rural versus urban adult-child caregivers caring for parents with dementia in China

Background: It is predicted that China will have the largest number of cases of dementia in the world by 2025 (Ferri et al., 2005). Research has demonstrated that caring for family members with dementia can be a long-term, burdensome activity resulting in physical and emotional distress and impairment (Pinquart & Sorensen, 2003b). The establishment of family caregiver supportive services in China can be considered urgent; and the knowledge of the caregiving experience and related influencing factors is necessary to inform such services. Nevertheless, in the context of rapid demographic and socioeconomic change, the impact of caregiving for rural and urban Chinese adult-child caregivers may be different, and different needs in supportive services may therefore be expected. Objectives: The aims of this research were 1) to examine the potential differences existing in the caregiving experience between rural and urban adult-child caregivers caring for parents with dementia in China; and 2) to examine the potential differences existing in the influencing factors of the caregiving experience for rural as compared with urban adult-child caregivers caring for parents with dementia in China. Based on the literature review and Kramer.s (1997) caregiver adaptation model, six concepts and their relationships of caregiving experience were studied: severity of the care receivers. dementia, caregivers. appraisal of role strain and role gain, negative and positive well-being outcomes, and health related quality of life. Furthermore, four influencing factors (i.e., filial piety, social support, resilience, and personal mastery) were studied respectively. Methods: A cross-sectional, comparative design was used to achieve the aims of the study. A questionnaire, which was designed based on the literature review and on Kramer.s (1997) caregiver adaptation model, was completed by 401 adult-child caregivers caring for their parents with dementia from the mental health outpatient departments in five hospitals in the Yunnan province, P.R. China. Structural equation modelling (SEM) was employed as the main statistical technique for data analyses. Other statistical techniques (e.g., t-tests and Chi-Square tests) were also conducted to compare the demographic characteristics and the measured variables between rural and urban groups. Results: For the first research aim, the results indicated that urban adult-child caregivers in China experienced significantly greater strain and negative well-being outcomes than their rural peers; whereas, the difference on the appraisal of role gain and positive outcomes was nonsignificant between the two groups. The results also indicated that the amounts of severity of care receivers. dementia and caregivers. health related quality of life do not have the same meanings between the two groups. Thus, the levels of these two concepts were not comparable between the rural and urban groups in this study. Moreover, the results also demonstrated that the negative direct effect of gain on negative outcomes in urban caregivers was stronger than that in rural caregivers, suggesting that the urban caregivers tended to use appraisal of role gain to protect themselves from negative well-being outcomes to a greater extent. In addition, the unexplained variance in strain in the urban group was significantly more than that in the rural group, suggesting that there were other unmeasured variables besides the severity of care receivers. dementia which would predict strain in urban caregivers compared with their rural peers. For the second research aim, the results demonstrated that rural adult-child caregivers reported a significantly higher level of filial piety and more social support than their urban counterparts, although the two groups did not significantly differ on the levels of their resilience and personal mastery. Furthermore, although the mediation effects of these four influencing factors on both positive and negative aspects remained constant across rural and urban adult-child caregivers, urban caregivers tended to be more effective in using personal mastery to protect themselves from role strain than rural caregivers, which in turn protects them more from the negative well-being outcomes than was the case with their rural peers. Conclusions: The study extends the application of Kramer.s caregiving adaptation process model (Kramer, 1997) to a sample of adult-child caregivers in China by demonstrating that both positive and negative aspects of caregiving may impact on the caregiver.s health related quality of life, suggesting that both aspects should be targeted in supportive interventions for Chinese family caregivers. Moreover, by demonstrating partial mediation effects, the study provides four influencing factors (i.e., filial piety, social support, resilience, and personal mastery) as specific targets for clinical interventions. Furthermore, the study found evidence that urban adult-child caregivers had more negative but similar positive experience compared to their rural peers, suggesting that the establishment of supportive services for urban caregivers may be more urgent at present stage in China. Additionally, since urban caregivers tended to use appraisal of role gain and personal mastery to protect themselves from negative well-being outcomes than rural caregivers to a greater extend, interventions targeting utility of gain or/and personal mastery to decrease negative outcomes might be more effective in urban caregivers than in rural caregivers. On the other hand, as cultural expectations and expression of filial piety tend to be more traditional in rural areas, interventions targeting filial piety could be more effective among rural caregivers. Last but not least, as rural adult-child caregivers have more existing natural social support than their urban counterparts, mobilising existing natural social support resources may be more beneficial for rural caregivers, whereas, formal supports (e.g., counselling services, support groups and adult day care centres) should be enhanced for urban caregivers.

Transition to day care for older people in Taiwan : a grounded theory study

Adult day care centres provide a means whereby frail or disabled older people can remain living at home particularly when their family care-givers engage in waged work. In Taiwan, adult day care services appear to meet the cultural needs of both older people and their families for whom filial care is vital. Little research attention has been paid to the use of day care services in Taiwan, the uptake rate of which is low. This grounded theory study explored the ways in which older people and family care-givers construct meanings around the use of day care services in Taiwan. Forty-four semi-structured interviews were undertaken with older people, care-givers and day care centre managers. The findings from grounded theory data analysis bring focus to the assumptions and structures that underpin the process of transition to day care services. A key feature of this process is the reconstruction of personal identity as both the older people and family care-givers work to make sense of the relationship between the self and a changing social structure. Reconstructing identity in a shifting world is the core category of the study and reflects a process of reframing whereby older people came to new definitions of social responsibility and independence within the context of the day care centre. Similarly, the family care-givers actively reformulated the concept of filial piety as they interacted with and interpreted the changes in economic and social conditions in Taiwan.

Avoidance of issues in family caregiving

Effective communication between older people and their family carers is necessary for providing appropriate and quality care. However, family carers and carereceivers may avoid discussing issues of concern and this may adversely affect the quality of the caring relationship. This study investigated the content of, and avoidance of issues in communication between 84 spousal and filial carers and carereceivers. The study findings indicate that family carers and carereceivers do avoid discussing issues of concern. Nurses working with families are well placed to promote more effective communication in the caring context to augment more satisfying caring relationships for both carers and carereceivers.

The quality of life and caregiving burden among caregivers of people with dementia in Hanoi, Bac Ninh and Hai Phong, Vietnam

This three phase study aimed to describe dementia carer's quality of life (QoL) and perceived burden, and explore the associations between family carer characteristics, burden and perceived QoL in Vietnam. Dementia carers in the capital, Hanoi, in Phase 1 (N= 153) and from Hanoi, Hai Phong and Bac Ninh in Phase 2 (N=347) completed questionnaires. Survey results showed dementia carers reported low QoL, predicted by high perceived burden. Other carer characteristics including age, gender, family income and perceived experience were significantly associated with QoL. Filial piety contributed to only a single domain of QoL. Phase 3 employed qualitative methods to explore the specific issues faced by daughter carers. Findings suggested that filial gratitude and positive aspects of the role may influence the caring experience of daughter carers. Further investigation of the specific support needs of general dementia carers, and daughter carers in particular, in Vietnam is warranted.

Reconstructing identity of older people in using day care services in Taiwan: A grounded theory study

Adult day care centers provide a means whereby frail or disabled older people can remain living at home particularly when their family care-givers engage in waged work. In Taiwan, adult day care services appear to meet the cultural needs of both older people and their families for whom filial care is vital. Little research attention has been paid to the use of day care services in Taiwan, the uptake rate of which is low. This grounded theory study explored the ways in which older people and family care-givers construct meanings around the use of day care services in Taiwan. The research methodology drew on the theoretical tenets of symbolic interactionism and methods were informed by the grounded theory. In-depth interviews with 30 participants were undertaken. Reconstructing identity in a shifting world is the core category of the study and reflects a process of reframing whereby older people came to new definitions of social responsibility and independence within the context of the day care center. The implications of the findings is that the older people, rather than seeking to be relieved of social responsibilities, worked very hard to frame and reframe a social role. Rather than letting the institutions undermine or disrupt their identity, the older people worked to actively negotiate and redefine the meaning of self. Thus, although reluctant to come to use the services at the outset, they found a way to manage their lives independently. Social roles and responsibilities as older parents were retained. This study explored the process of meaning construction of day care use and the ways in which this process entailed a reconstruction of the identities of the participants. The evidence from this study underlines the importance of recognizing and acknowledging subjectively conceived identities as work that older people undertake, when in care, to render their lives meaningful.

Group fission in Nilgiri langurs (Presbytis johnii)

During a field study on habituated groups of wild Nilgiri langurs (Presbytis johnii), four cases of group fission were observed which differed markedly from group changes reported in other species of the same genus. All fissions occurred in groups with more than one mature male and roughly coincided with the onset of loud call vocalization by the second mature male group member. As a result of the fission the founder group factions acquired the structure of a onemale group. The filial factions consisted of both mature males and females and occupied, at least temporarily, a part of, or an area adjacent to, the founder group. During fission, the amount of aggressive interactions between the two mature males increased. However, the majority of agonistic interactions involved ritualized threat and intimidation behavior without physical aggression. In at least three cases the two mature males involved in the fission had not joined recently but had lived in these groups for three years or more. Although the presence of all male bands and single males in the two study populations indicate that male replacement by invasive takeovers may occur, it is suggested that in Nilgiri langurs, noninvasive fissions are probably another common mechanism for the foundation and maintenance of bisexual one-male groups.

A imprescritibilidade da negatória de paternidade e o melhor interesse da criança

Estudo sobre a filiação com ênfase na regra do caput do artigo 1.601 do Código Civil Brasileiro Lei 10.406/2002, segundo a qual cabe ao marido o direito de contestar a paternidade dos filhos nascidos de sua mulher, sendo tal ação imprescritível. A dissertação tem como objetivo principal demonstrar a inconstitucionalidade do direito perpétuo do pai em desconstituir a paternidade do filho menor nascido em uma relação de casamento à luz do princípio do melhor interesse da criança. Para tanto foi realizada pesquisa bibliográfica e jurisprudencial em tribunais nacionais de segunda instância, no Superior Tribunal de Justiça e no Supremo Tribunal Federal. Os critérios da presunção legal pater is est quem nuptiae demonstrant, da verdade biológica e da posse de estado de filho foram um a um analisados, não havendo entre eles predominância no ordenamento jurídico. O levantamento deste material permitiu a constatação de que a regra supracitada é, pela doutrina majoritária, acriticamente louvada e utilizada nos julgados de conflitos de paternidade. O filho, no entanto, não pode permanecer por toda a vida sujeito à possibilidade do pai desfazer, a qualquer momento, a relação paterno-filial pela ausência do dado biológico por que: (i) o exercício deste direito é mutilador de sua identidade e dignidade humana; (ii) a posse de estado de filho confirma a presunção pater is est; (iii) o estado civil de filho deve se tornar certo e estável em um curto período de tempo. Sustenta-se que é imperioso o afastamento por inconstitucionalidade material da regra do artigo 1.601 do Código Civil e a aplicação analógica do prazo de quatro anos previsto no artigo 1.614 do Código Civil. De lege ferenda propõe-se a elaboração de uma norma que fixe um prazo decadencial para que o marido e pai possa exercer o direito potestativo de negar a paternidade.

Análise de quadrigramas na escrita em inglês como língua estrangeira: um estudo baseado em corpus

O presente estudo tem como objetivo geral traçar um perfil das escolhas léxico-gramaticais da escrita em inglês de um grupo de aprendizes brasileiros na cidade do Rio de Janeiro, ao longo dos anos de 2009 a 2012, através da análise de sua produção de quadrigramas (ou blocos de quatro itens lexicais usados com frequência por vários aprendizes) em composições escritas como parte da avaliação final de curso. Como objetivo específico, a pesquisa pretendeu analisar se os quadrigramas produzidos estavam dentre aqueles que haviam sido previamente ensinados para a execução da redação ou se pertenceriam a alguma outra categoria, isto é, quadrigramas já incorporados ao uso da língua ou quadrigramas errôneos usados com abrangência pela população investigada. Para tal, foram coletadas composições escritas por aprendizes de mesmo nível de proficiência de várias filiais de um mesmo curso livre de inglês na cidade do Rio de Janeiro. Em seguida, essas composições foram digitadas e anotadas para constituírem um corpus digital facilmente identificável em termos do tipo e gênero textual, perfil do aprendiz, filial e área de origem do Rio de Janeiro. O estudo faz uso de preceitos e métodos da Linguística de Corpus, área da Linguística que compila grandes quantidades de textos e deles extrai dados com o auxílio de um programa de computador para mapear uso, frequência, distribuição e abrangência de determinados fenômenos linguístico ou discursivo. O resultado demonstra que os aprendizes investigados usaram poucos quadrigramas ensinados e, coletivamente, preferiram usar outros que não haviam sido ensinados nas aulas específicas para o nível cursado. O estudo também demonstrou que quando o gênero textual faz parte de seu mundo pessoal, os aprendizes parecem utilizar mais quadrigramas previamente ensinados. Isto pode querer dizer que o gênero pode influenciar nas escolhas léxico-gramaticais corretas. O estudo abre portas para se compreender a importância de blocos léxico-gramaticais em escrita em L2 como forma de assegurar fluência e acuracidade no idioma e sugere que é preciso proporcionar maiores oportunidades de prática e conscientização dos aprendizes quanto ao uso de tais blocos

Hybrids between olive flounder Paralichthys olivaceus and stone flounder Kareius bicoloratus: karyotype, allozyme and RAPD analyses

The hybrid between olive flounder Paralichthys olivaceus and stone flounder Kareius bicoloratus was produced by artificial insemination of olive flounder eggs with stone flounder sperm. Sinistral and dextral are two types of hybrid progeny after metamorphosis. Karyotypes of both hybrid flounders are the same as those of the two parental species. Of the 22 loci examined from 12 allozymes, 12 confirmed hybridization of the paternal and maternal loci in hybrids and no difference was found in allozyme patterns of sinistral and dextral hybrid fishes. RAPD patterns of these specimens were also studied with 38 primers selected from 104 tested. Among them, the PCR products of 30 primers showed hybridization of the paternal and maternal bands. Genetic variation between hybrids and their parental stocks was analyzed by RAPD using 10 of the above 38 primers. The average heterozygosity and genetic distance were calculated. The results suggested that the filial generation could inherit a little more genetic materials from paternal fish than that from maternal fish.

Exploring the Zionist evolution of Robert Briscoe: History and memory

Robert Briscoe was the Dublin born son of Lithuanian and German-Jewish immigrants. As a young man he joined Sinn Féin and was an important figure in the War of Independence due to a role as one of the IRA’s main gun-procuring agents. He took the anti-Treaty side during an internecine Civil War, mainly due to the influence of Eamon de Valera and retained a filial devotion towards him for the rest of his life. In 1926 he was a founding member of Fianna Fáil, de Valera’s breakaway republican party, which would dominate twentieth-century Irish politics. He was first elected as a Fianna Fáil T.D. (Teachta Dála, Deputy to the Dáil) in 1927, and successfully defended his seat eleven times becoming the first Jewish Lord Mayor of Dublin in 1956, an honour that was repeated in 1961. On this basis alone, it can be argued that Briscoe was a significant presence in an embryonic Irish political culture; however, when his role in the 1930s Jewish immigration endeavor is acknowledged, it is clear that he played a unique part in one of the most contentious political and social discourses of the pre-war years. This was reinforced when Briscoe embraced Zionism in a belated realisation that the survival of his European co-religionists could only be guaranteed if an independent Jewish state existed. This information is to a certain degree public knowledge; however, the full extent of his involvement as an immigration advocate for potential Jewish refugees, and the seniority he achieved in the New Zionist Organisation (Revisionists) has not been fully recognised. This is partly explicable because researchers have based their assessment of Briscoe on an incomplete political archive in the National Library of Ireland (NLI). The vast majority of documentation pertaining to his involvement in the immigration endeavor has not been available to scholars and remains the private property of Robert Briscoe’s son, Ben Briscoe. The lack of immigration files in the NLI was reinforced by the fact that information about Briscoe’s Revisionist engagement was donated to the Jabotinsky Institute in Tel Aviv and can only be accessed physically by visiting Israel. Therefore, even though these twin endeavors have been commented on by a number of academics, their assessments have tended to be based on an incomplete archive, which was supplemented by Briscoe’s autobiographical memoir published in 1958. This study will attempt to fill in the missing gaps in Briscoe’s complex political narrative by incorporating the rarely used private papers of Robert Briscoe, and the difficult to access Briscoe files in Tel Aviv. This undertaking was only possible when Mr.Ben Briscoe graciously granted me full and unrestricted access to his father’s papers, and after a month-long research trip to the Jabotinsky Institute in Tel Aviv. Access to this rarely used documentation facilitated a holistic examination of Briscoe’s complex and multifaceted political reality. It revealed the full extent of Briscoe’s political and social evolution as the Nazi instigated Jewish emigration crisis reached catastrophic proportions. He was by turn Fianna Fáil nationalist, Jewish immigration advocate and senior Revisionist actor on a global stage. The study will examine the contrasting political and social forces that initiated each stage of Briscoe’s Zionist awakening, and in the process will fill a major gap in Irish-Jewish historiography by revealing the full extent of his Revisionist engagement.

Speciation and distribution of arsenic and localization of nutrients in rice grains

Arsenic (As) contamination of rice grains and the generally low concentration of micronutrients in rice have been recognized as a major concern for human health. Here, we investigated the speciation and localization of As and the distribution of (micro)nutrients in rice grains because these are key factors controlling bioavailability of nutrients and contaminants. Bulk total and speciation analyses using high-pressure liquid chromatography (HPLC)-inductively coupled plasma mass spectrometry (ICP-MS) and X-ray absorption near-edge spectroscopy (XANES) was complemented by spatially resolved microspectroscopic techniques (micro-XANES, micro-X-ray fluorescence (micro-XRF) and particle induced X-ray emission (PIXE)) to investigate both speciation and distribution of As and localization of nutrients in situ. The distribution of As and micronutrients varied between the various parts of the grains (husk, bran and endosperm) and was characterized by element-specific distribution patterns. The speciation of As in bran and endosperm was dominated by As(III)-thiol complexes. The results indicate that the translocation from the maternal to filial tissues may be a bottleneck for As accumulation in the grain. Strong similarities between the distribution of iron (Fe), manganese (Mn) and phosphorus (P) and between zinc (Zn) and sulphur (S) may be indicative of complexation mechanisms in rice grains.
