Geophysical Computer Program 11

Program HYPOERR evaluates the performance of a small network of arbitrary seismic arrays in determining coordinates and times of seismic events. A linearized inversion following the method of Uhrhammer (1980)is performed for a layered velocity structure by determining the eigenvalues and eigenvectors of the partial derivatives of travel time for P and/or S phases with respect to hypocenter position and origin time for each station in the array. A series of covariance matrices is then obtained to evaluate statistical errors for a specified grid of hypocenter locations at any given depth. Contour plots can then be made of the matrix elements by using standard contouring software. Examples are given for ( 1) the case of a hypothetical quadrapartite array and (2) an actual eight-station ocean-bottom seismometer array deployed around the 95.5° W. Galapagos propagating-rift zone

Una Vida Sin Palabras?: Disability, Subalternity and the Sandinista Revolution

This paper offers an analysis of the documentary film, Una Vida Sin Palabras [A life without words] (2011). The film follows a short period in the lives of a campesino family living in a rural area of Nicaragua as a teacher of Nicaraguan sign language, working for a local NGO, endeavours to teach three deaf siblings how to sign. Bringing together the critical practices of Disability and Subaltern studies in the specific context of contemporary Nicaragua, the paper argues: (1) that the film ultimately re-inscribes and reinforces the subalternity of the disabled subjects it sets out to portray; and (2) that the hierarchy it produces between its object – the deaf family – and its implied educated, metropolitan audience replays some influential (but, we would argue, politically limited) critiques of the failure of the first Sandinista Government (1979-1990) and other broad based radical political movements to represent the national popular. In so doing, the paper also makes a case for the political and intellectual importance of bringing a Critical Disability Studies perspective to the field of Subaltern Studies, and argues that an engagement with the problems that are presented by this film at the level of both form and content raise some important questions for both fields of enquiry

Toward Understanding Person–Place Transactions in Neighborhoods: A Qualitative-Participatory Geospatial Approach

Background and Objectives Emerging research regarding aging in neighborhoods emphasizes the importance of this context for well-being; however, in-depth information about the nature of person–place relationships is lacking. The interwoven and complex nature of person and place points to methods that can examine these relationships in situ and explore meanings attached to places. Participatory geospatial methods can capture situated details about place that are not verbalized during interviews or otherwise discerned, and qualitative methods can explore interpretations, both helping to generate deep understandings of the relationships between person and place. This article describes a combined qualitative-geospatial approach for studying of older adults in neighborhoods and investigates the qualitative-geospatial approach developed, including its utility and feasibility in exploring person–place transactions in neighborhoods. Research Design and Methods We developed and implemented a qualitative-geospatial approach to explore how neighborhood and person transact to shape sense of social connectedness in older adults. Methods included narrative interviews, go-along interviews, and global positioning system tracking with activity/travel diary completion followed by map-based interviews. We used a variety of data analysis methods with attention to fully utilizing diverse forms of data and integrating data during analysis. We reflected on and examined the utility and feasibility of the approach through a variety of methods. Results Findings indicate the unique understandings that each method contributes, the strengths of the overall approach, and the feasibility of implementing the approach. Discussion and Implications The developed approach has strong potential to generate knowledge about person–place transactions that can inform practice, planning, policy, and research to promote older adults’ well-being

Fishing For Food: Values and Benefits Associated With Coastal Infrastructure

While there is substantial literature about the socio-cultural characteristics and values associated with recreational and commercial fisheries in the U.S., studies directed at those who ‘fish for food’—those who depend on consuming their catch to various degrees—are relatively sparse. Using qualitative data collected through 80 semi-structured interviews with fishers in the summer and fall of 2018 in Carteret County, North Carolina, this study aims to better understand the group of recreational fishers who consume their catch by describing social and cultural dimensions and values associated with fishing for food, examining the role of infrastructure in facilitating access to benefits associated with this activity, and considering how knowledge of existing licensing regulations surrounding subsistence license waivers affect this fishing community. Interviews conducted at free public fishing structures in the region revealed that fishers derive a variety of values and benefits from fishing at these sites, including access to recreation, nutrition, a social community, and mental health benefits, which were found to be negatively impacted by Hurricane Florence in September 2018. We also found an informal economy of sharing catch on- and off-site that extends the reach and benefits facilitated by public infrastructure to people beyond those using it directly. Overall, we call for conceptualizations of ‘fishing for food’ that include aspects that go beyond traditional definitions of ‘subsistence’ or ‘recreational’ fishing such as food security, access, and less obvious social and cultural motivations behind the activity. These findings are a compelling rationalization for the creation and maintenance of formal and informal fishing places locally and, by extension, in other coastal areas, given the array of benefits provided by access to these types of locations

Nonconstant electronic density of states tunneling inversion for A15 superconductors: Nb3Sn

We re-examine the tunneling data on A15 superconductors by performing a generalized McMillan-Rowell tunneling inversion that incorporates a nonconstant electronic density of states obtained from band-structure calculations. For Nb3Sn, we find that the fit to the experimental data can be slightly improved by taking into account the sharp structure in the density of states, but it is likely that such an analysis alone is not enough to completely explain the superconducting tunneling characteristics of this material. Nevertheless, the extracted Eliashberg function displays a number of features expected to be present for the highest quality Nb3Sn samples.Comment: 11 pages, 11 figure

Promoting critically informed learning and knowing about occupation through conference engagements

As occupation-focused discussions and applications of critical theoretical perspectives increase, attention must also be paid to how different spaces of knowledge dissemination, exchange, and production support critically informed learning and knowing about occupation. This paper presents the reflections of a group of international scholars and lecturers whose shared interest in critical theoretical perspectives prompted the incremental co-development of a series of conference engagements. We describe how our group came together, what kinds of learning experiences we developed to promote and support engagement with critical theoretical perspectives, and what understandings we gained through ongoing critical reflexivity about those learning experiences. Our discussion addresses two problematics related to conferences as learning spaces: inclusion, and sustained engagement with epistemic communities and ideas that may form through critically oriented conference sessions. We also discuss how enacting critical pedagogies and principles of ‘unconferencing’ may better promote critically informed ways of learning and knowing occupation than typical conference structures. The paper ends with a call for continued integration of varied critically informed teaching and learning opportunities at conferences, as a means of further encouraging diverse types of knowledge production, sharing, and learning about occupation

Legitimizing intimate partner violence: the role of romantic love and the mediating effect of patriarchal ideologies

Romantic love in heterosexual relationships is recognized as an important aspect to be considered in relation to the psychosocial mechanisms associated with the persistence of intimate partner violence and the help-seeking barriers faced by female victims. However, few studies have explored the processes underlying the relationship between this form of love and attitudes toward this kind of violence. To do this, the current study aims to analyze the relationship between the adherence to romantic love and the legitimization of intimate partner violence (i.e., perceived severity of violence, victim blame, and exoneration of the perpetrator). It was also to test the mediating effect of patriarchal ideologies (i.e., ambivalent sexism and domestic violence myths) on this relationship. Two hundred thirty-five French adults (51.1% women) were surveyed. The data were analyzed with structural equation models to study the mediations between the variables considered. Consistent with our hypotheses, the results showed that the more the participants adhered to romantic love, the more they blamed the victim and exonerated the perpetrator. They also showed a positive link between romantic love, ambivalent sexism, and domestic violence myths. Finally, the results demonstrated that the relationship between romantic love and the legitimization of violence is mediatized by ambivalent sexism and domestic violence myths. The findings illustrate the need to deconstruct romantic love ideology and the psychosocial logics underlying the legitimization of intimate partner violence.info:eu-repo/semantics/publishedVersio

The bubble snails (Gastropoda, Heterobranchia) of Mozambique: an overlooked biodiversity hotspot

This first account, dedicated to the shallow water marine heterobranch gastropods of Mozambique is presented with a focus on the clades Acteonoidea and Cephalaspidea. Specimens were obtained as a result of sporadic sampling and two dedicated field campaigns between the years of 2012 and 2015, conducted along the northern and southern coasts of Mozambique. Specimens were collected by hand in the intertidal and subtidal reefs by snorkelling or SCUBA diving down to a depth of 33 m. Thirty-two species were found, of which 22 are new records to Mozambique and five are new for the Western Indian Ocean. This account raises the total number of shallow water Acteonoidea and Cephalaspidea known in Mozambique to 39 species, which represents approximately 50 % of the Indian Ocean diversity and 83 % of the diversity of these molluscs found in the Red Sea. A gap in sampling was identified in the central swamp/mangrove bio-region of Mozambique, and therefore, we suggest that future research efforts concentrate on or at least consider this region.publishedVersio
