(Appendix) Grain-size distribution, calcium carbonate content and proportion of cemented aggregates in ODP Site 133-820

The textural and compositional characteristics of the 400 m sequence of Pleistocene wackestones and packstones intersected at Ocean Drilling Program (ODP) Site 820 reflect deposition controlled by fluctuations in sea-level, and by variations in the rate of sediment supply. The development of an effective reefal barrier adjacent to Site 820, between 760 k.y. and 1.01 Ma, resulted in a marked reduction in sediment accumulation rates on the central Great Barrier Reef outermost shelf and upper slope. This marked change corresponds with the transition from sigmoidal prograding seismic geometry in the lower 254 m of the sequence, to aggradational geometry in the top 146 m. The reduction in the rate of sediment accumulation that followed development of the reefal barrier also caused a fundamental change in the way in which fluctuations in sea-level controlled sediment deposition. In the lower, progradational portion of the sequence, sea-level cyclicity is represented by superimposed coarsening-upward cycles. Although moderately calcareous throughout (mostly 35%-75% CaCO3), the depositional system acted in a similar manner to siliciclastic shelf depositional systems. Relative sea-level rises resulted in deposition of more condensed, less calcareous, fine, muddy wackestones at the base of each cycle. Sea-level highstands resulted in increased sedimentation rates and greater influx of coarse bioclastic material. Continued high rates of sedimentation of both coarse bioclastic material and mixed carbonate and terrigenous mud marked falling and low sea-levels. This lower part of the sequence therefore is dominated by coarse packstones, with only thin wackestone intervals representing transgressions. In contrast, sea-level fluctuations following formation of an effective reefal barrier produced a markedly different sedimentary record. The more slowly deposited aggradational sequence is characterized by discrete thin interbeds of relatively coarse packstone within a predominantly fine wackestone sequence. These thin packstone beds resulted from relatively low sedimentation rates during falling and low sea-levels, with much higher rates of muddy sediment accumulation during rising and high sea-levels. The transition from progradational to aggradational sequence geometry therefore corresponds to a transition from a "siliciclastic-type" to a "carbonate-type" depositional system.

Age model and stable isotopes of sediment cores from north-central Chile and south-central Chile

Terrigenous sediment supply, marine transport, and depositional processes along tectonically active margins are key to decoding turbidite successions as potential archives of climatic and seismic forcings. Sequence stratigraphic models predict coarse-grained sediment delivery to deep-marine sites mainly during sea-level fall and lowstand. Marine siliciclastic deposition during transgressions and highstands has been attributed to sustained connectivity between terrigenous sources and marine sinks facilitated by narrow shelves. To decipher the controls on Holocene highstand turbidite deposition, we analyzed 12 sediment cores from spatially discrete, coeval turbidite systems along the Chile margin (29° - 40°S) with changing climatic and geomorphic characteristics but uniform changes in sea level. Sediment cores from intraslope basins in north-central Chile (29° - 33°S) offshore a narrow to absent shelf record a shut-off of turbidite deposition during the Holocene due to postglacial aridification. In contrast, core sites in south-central Chile (36° - 40°S) offshore a wide shelf record frequent turbidite deposition during highstand conditions. Two core sites are linked to the Biobío river-canyon system and receive sediment directly from the river mouth. However, intraslope basins are not connected via canyons to fluvial systems but yield even higher turbidite frequencies. High sediment supply combined with a wide shelf and an undercurrent moving sediment toward the shelf edge appear to control Holocene turbidite sedimentation and distribution. Shelf undercurrents may play an important role in lateral sediment transport and supply to the deep sea and need to be accounted for in sediment-mass balances.

Hurt feelings in couple relationships: Exploring the role of attachment and perceptions of personal injury

This research program focused on perceptions of the appraisals and emotions involved in hurtful events in couple relationships. Study I tested the broad proposition that hurt feelings are elicited by relational transgressions that generally imply relational devaluation and that evoke a sense of personal injury by threatening positive mental models of self and/or others. Participants (N = 224) provided retrospective accounts of an experience of being hurt by a romantic partner. These accounts, together with expert judges' ratings, showed that most hurtful events involved relational transgressions that signal both relational devaluation and threat to positive mental models; however, relational devaluation was relatively unimportant in explaining the hurt associated with partners' distrust. A sense of injury emerged as the dominant theme in open-ended accounts of emotional reactions; however, other negative emotions also featured and were related to the type of event reported. The emotion terms generated in Study I were used as stimuli in a word-sorting task (Study 2). This study confirmed that many of the terms were perceived specifically as injury related, and shed further light on the link between appraisals and emotions. Theoretical and practical implications of the findings are discussed.

Victim-perpetrator differences in reports of hurtful events

This research project addressed limitations identified in previous studies of role differences (victim vs. perpetrator) in evaluations of hurtful events. The study employed multiple methods (open-ended and structured retrospective reports and experience-sampling diary records), and involved a community sample of both dating and married couples. Retrospective reports indicated that the extent and direction of role-related differences varied markedly across dependent measures. Further, role differences were moderated by forgiveness, but not relationship status, relationship satisfaction, or event severity. Diary records pointed to the ambiguity inherent in many communication acts as contributing to differing perceptions of hurtful events. Results are discussed in terms of theories of interdependence and self-presentation and in terms of the complex and often ambiguous nature of couples' communication processes.

A TRANSGRESSÃO SERTANEJA DO GÊNERO RELATÓRIO: Revelação do escritor no texto do prefeito Graciliano Ramos

Esta tese se propõe a investigar o gênero relatório, a fim de conhecer seus traços constitutivos, seu contexto situacional e a função sócio comunicativa que exerce em sua comunidade discursiva. Forma o objeto desta pesquisa os relatórios públicos escritos pelo prefeito Graciliano Ramos, nos anos de 1929 e 1930, e enviados ao governador do estado de Alagoas. Estes documentos alcançaram grande repercussão na época, devido ao tom irônico e ousado presente em seus textos que indicam uma transgressão da escritura do gênero relatório. Foram definidas para a unidade de análise as figuras de linguagem, na perspectiva de Quintiliano de Calahorra e sua incidência nestes textos prestando atenção nas transgressões praticadas pelo escritor gestor. Para alcançar os objetivos, a metodologia adotada foi o da análise da padronização de texto e textualização proposto por Bhatia, que compartilha com o da análise da expressão, de Lawrence Bardin.

PERCEPÇÃO DE FATORES E SITUAÇÕES DE RISCO EM MOTORISTAS INFRATORES

O presente estudo teve como objetivo verificar a percepção de situações de acidentes de trânsito por motoristas infratores; levantar dados sócio-demográficos, fatores de riscos e fatores de proteção de motoristas infratores, como também verificou a percepção de invulnerabilidade destes motoristas infratores. A coleta de dados foi realizada através da aplicação de Escala de Percepção de Invulnerabilidade, questionário sócio-demográfico que visou caracterizar o condutor, e entrevista semi-estruturada com finalidade de conhecer as ações do condutor ao volante. A amostra foi realizada por acessibilidade. Foi adotado como critério de inclusão na amostra motoristas habilitados que acumularam mais de vinte pontos em seu prontuário da Carteira de habilitação. O estudo teve um total de 427 sujeitos, sendo 325 do gênero masculino e 102 do gênero feminino. As infrações mais cometidas foram as gravíssimas para os sujeitos habilitados entre 6 e 15 anos, independente do gênero. Em relação à Escala de Invulnerabilidade, identificou-se que a autopercepção positiva foi superior ao senso de proteção e a crença na invulnerabilidade dos sujeitos. Os sujeitos entrevistados têm em média 38 pontos no prontuário, mas consideram-se motoristas cautelosos, atentos, cuidadosos, preocupados com os outros e que procuram obedecer às leis. Verificou-se que o risco está associado com a idéia de perigo, causar danos a outras pessoas ou comprometer sua segurança. As situações de risco estão associadas ao volume excessivo de veículos, alta velocidade, não obediência às leis de trânsito, veículos mal conservados e falta de sinalização. A percepção de riscos tem muito mais a ver com a singularidade do indivíduo diante de algum evento do que com uma estimativa correta de probabilidades. Constatou-se que os níveis elevados de ameaça sempre apresentam estratégias cognitivas de minimização do risco e do seu impacto. Constatou-se que as infrações de trânsito que ocorrem têm a ver com o contexto social. Investigar sobre as possíveis variáveis psicológicas nesse contexto também é uma tarefa de grande amplitude. Os estudos realizados nessa área da psicologia de trânsito no Brasil podem dar mais um passo em direção à compreensão da complexa rede de relações envolvendo o homem, o trânsito e o ambiente.(AU)

Lan American Coups: Have They Vanished or Taken New Shapes?

In the following pages, three well-known Latinoamericanists share their views on the current prospects for coups in Latin America. They are: Rut Diamint of the University Torcuatto de Tella in Buenos Aires, Argentina; Pablo Policzer of the University of Calgary in Canada; and Michael Shifter of the Inter-American Dialogue in Washington, DC. Each looks at the potential for coups from different perspectives but, all three come to similar conclusions. That is, that despite substantial gains in democracy, the threat of coups in Latin America remains latent. The authors agree that democracy is growing in the region. Opinion surveys such as the Americas Barometer consistently show that citizens in Latin America have gradually incorporated democracy as part of their core value system. Yet, the authors argue convincingly that Latin America faces new types of interruptions to its democratic process that should be considered coups, even if not following the traditional style of military coup that predominated in the past. Situations that have taken place in Peru, Ecuador, Nicaragua, Honduras and other countries serve to illustrate the new trends. More specifically, Professor Diamint argues that in Latin America a culture of intolerance, demonization of the opposition, and the utilization of any method to achieve power prevails. In a region with a very high threshold of violence, governments fail to set an example of establishing a culture of debate, consensus, and transparency. This culture is inclined to uncontrollable political expressions, preferring confrontational means to resolve conflict. Within this scenario, “messianic” solutions are promoted and coups cannot be discarded as an option that would never transpire. Professor Policzer looks more closely to the constitutional loopholes that allow for a transformation of limited into absolute power. He argues that coups can be constitutional or unconstitutional, and that a constitutional coup can occur when violations to democracy actually stem from the constitutions themselves. In Honduras, for example specific provisions in the Constitution itself created conditions for a constitutional crisis; similar provisions have also led to constitutional authoritarianism in Venezuela and other countries. Dr. Policzer stresses that when a head of state or the military take absolute power, even temporarily, based on provisions in their constitutions; they are in essence staging a constitutional coup. These blind spots in constitutions, he argues, may be more serious threat to democracy than that of traditional coups. Lastly, Dr. Shifter argues that some kind of coup should be expected in Latin America in coming years, not only because fundamental institutions remain weak in some countries, but because the regional political environment is less prepared to respond effectively to transgressions than it was a few years ago. The good news, however, is that only a handful of countries, show no interest in governing. The bad news is that in those few countries where situations are indeed shaky, they are also in some cases aggravated by rising food and fuel prices, and spreading criminality, which pose serious risks to the rule of law and democratic governance.

A study of the relationship between employee virtuality and technology deviance as mediated by leadership and employee perceptions

Recent studies found that organizations have been investing significant capital in developing teams and employees in geographic areas where labor and resources are considerably cheaper. Furthermore, organizations are moving core operational activities such as research and development and back-office processes to globally distributed teams. ^ However, several factors that are inherent to these virtual teams can have a negative impact on employee perceptions and engagement; specifically, the physical and temporal differences between employees and their supervisors, the lack of meaningful social interaction intrinsic to working relationships, and cultural biases that can be fostered when close, daily interactions is not there to help bridge the dissimilarity. ^ When strategies are not in place to mitigate these deficiencies, it can cause virtual employees to disengage emotionally and intellectually from the organization, or lead them to feel justified in working against the best interest of the company. ^ Past research indicates that although deviant behavior in the workplace is not new, transgressions committed by employees have been increasing significantly every year. Beyond the focus of why employees are motivated to act against the organization, to what extent do the recent changes to the organization’s structure influence this type of behavior through their actions at the macro (organizational) and micro level (leadership). ^ In addition, there is a related phenomenon that has aided the transformation of the workplace—namely, the ubiquity of technology. In the context of workplace deviance, established research has documented an increasing trend of employees utilizing company technology as a medium and amplifier when harming the organization. It is important to understand whether technology has facilitated or hindered workplace deviance by virtue of the technology itself (as a means), and as part of the new employee roles created by the evolving technology (i.e., virtual employees). Therefore, it is important to identify how individual attitudes and behaviors can be affected by an employee’s degree of virtuality. ^ This study will add to the understanding of how social interaction and physical proximity, leadership and other perception factors contribute to the changes organizations are experiencing as their structure evolves and adapts to compete in the new global environment. ^

Uma descrição sonora contemporânea do imagético tradicional armorial como subsídio para abordagens interpretativas do ciclo de canções “Visagem” de Nelson Almeida

This study suggests sonorous ambiences from the propose of images configured according to the description in “A Visagem da Moça Caetana” by Ariano Suassuna in order to create individual sonorous possibilities that may help musicians to play the piece. The cycle, composed in 1996 (for voice, viola, cello, bass clarinet/clarinet), is formed by three untitled songs. Its text is an excerpt from the “Folheto XLIV”, from the Romance d’A Pedra do Reino e o príncipe do sangue do vai-e-volta, and describes a sentence of death illustrated by symbols of the Armorial imagery, with neologisms and the peculiar accent from the Sertão in northeast Brazil. In addition to the analysis of technical difficulties to play, this study informs interpreters of the sonorous timbre and texture used by Nelson Almeida to describe tradition through contemporary musical language. The metaphors and transgressions of reason in Suassuna’s book were explored to create three image compositions so that they may lead interpreters to the sonorous description of the inanimate objects and the affections to which the poetry refers, expanding any technical-interpretative indications limited by musical notation. This research used the Visagem scores, the literature on the theme, discussions with the musicians that played the piece, interviews with Almeida, and composers’ reports. To illustrate the theory, the three images are available, printed as woodcut in cordel literature.

Black Femininity through the White Speculum: The Implications of Medicosocialism and the Disproportionate Regulation of Black Women’s Reproductive Autonomy

At the crux of health disparities for women of color lies a history of maltreatment based on racial difference from their white counterparts. It is their non-whiteness that limits their access to the ideologies of “woman” and “femininity” within dominant culture. As the result of this difference, the impact of the birth control movement varied among women based on race. This project explores how the ideology attributed to the black female body limited black women’s access to “womanhood” within dominant culture, and analyzes the manners in which their reproductive autonomy was compromised as the result of changes to that ideology through time. This project operates under the hypothesis that black women’s access to certain aspects of femininity such as domesticity and motherhood reflected their roles in slave society, that black women’s reproductive value was based on the value of black children within slave culture, and that both of these factors dictated the manner in which their reproductive autonomy was managed by health professionals. Black people’s worth as a free labor force within dominant culture diminished when the Reconstruction Amendments were added to the constitution and slavery was deemed unconstitutional—resulting in the paradigmatic shift from the promotion of black fertility to its recession. America’s transition to the medicosocial regulation of black fertility through Eugenics, the role of the black elite in the movement, and the negative impact of this agenda on the reproductive autonomy of black women from low socioeconomic backgrounds are enlisted as support. The paper goes on to draw connections between post-slavery ideology of black femininity and modern-day medicosocial occurrences within clinical settings in order to advocate for increased bias training for medical professionals as a means of combating current health disparities. It concludes with the possibility that this improvement in medical training could persuade people of color to seek out medical intervention at earlier stages of illness and obtain regular check-ups by actively countering physicians’ past transgressions against them.

Chemistry of interstitial waters of ODP Leg 117 samples (Table 1)

Interstitial water analyses made at 12 sites during Leg 117 are used to define the nature of diagenetic reactions in organic-rich sediments on the Owen Ridge and Oman Margin. Minor variations in chloride concentration profiles are ascribed to past changes in bottom water salinity at two mid-depth margin sites and to upward migration of low salinity water at another. There is no evidence for subsurface brine movement, unlike the case on the Peru Margin. Dolomitization is widespread and accounts for the depletions of magnesium observed in pore waters at variable depths at nearly all sites. The mineral occurs both as disseminated euhedral limpid crystals and, in at least one location, in massive stringers. Formation of the latter is suggested to reflect precipitation during sea level transgressions when the sedimentation rate was low, but when productivity was high. Authigenic carbonate fluorapatite is also widespread, the phosphorus being derived from the breakdown of organic matter. Sulfate is quantitatively depleted at depth at most locations but the rate of depletion is markedly less than that observed on the Peru Margin where sedimentation is also similarly influenced by high rates of upwelling. The reason for this contrast is not clear and merits further investigation.

El periodismo deportivo condicionado por la gestión comunicativa de los clubes de fútbol: el caso del FC Barcelona

Las relaciones entre los gabinetes de Comunicación de los clubes de fútbol y los periodistas deportivos se enmarcan en el modelo de Gieber y Johnson (1961) por el que el hecho de que ambos compartan objetivos comunes, donde los gabinetes de Comunicación necesitan que los medios publiquen determinadas informaciones y los periodistas precisan de noticias que publicar, provoca una pérdida de independencia por parte de los periodistas, ya que necesitan a esos departamentos como fuentes. En la actualidad, los departamentos de Comunicación de los clubes de fútbol, como el del FC Barcelona, se han constituido en gatekeepers. Esto ha acentuado las históricas diferencias que existen entre los periodistas y los profesionales de la comunicación corporativa, incrementado por el control informativo de estos departamentos lo que provoca constantes tensiones entre ambos.

Latina Super-heroines: Hot Tamales in Tights vs. Women Warriors, Wrestlers and Guerrilla Fighters of La Raza

The year 1977 saw the making of the first Latino superhero by a Latino artist. From the 1980s onwards it is also possible to find Latina super-heroines, whose number and complexity has kept increasing ever since. Yet, the representations of spandexed Latinas are still few. For that reason, the goal of this paper is, firstly, to gather a great number of Latina super-heroines and, secondly, to analyze the role that they have played in the history of American literature and art. More specifically, it aims at comparing the spandexed Latinas created by non-Latino/a artists and mainstream comic enterprises with the Latina super-heroines devised by Latino/a artists. The conclusion is that whereas the former tend to conceive heroines within the constraints of the logic of Girl Power, the latter choose to imbue their works with a more daring political content and to align their heroines with the ideologies of Feminism and Postcolonialism.
