The Multilink model that Dijkstra, Wahl, Buytenhuijs, van Halem, Al-jibouri, de Korte, and Rekké (2018) present is an excellent example that connects empirical patterns obtained from behavioral studies with mechanisms that can be implemented in computational models. We have previously argued that implementation of computational models is important because it forces the researchers to be explicit about assumptions and to specify parameters and variables that may be absent in verbal models. The Multilink model, along with BIA/BIA+ and many other models, provides concrete hypotheses regarding the role of variables such as word frequency, word length, orthographic similarity, and phonological neighborhood for researchers to test and verify against empirical data (see examples in the special issue on computational modeling published in this journal; Li, 2013).

High-speed railway "Moscow-Kazan" by the draft crosses the Volga (Kuibyshev reservoir) in Chuvashia region 500 m below the village of New Kushnikovo. The crossing plot is a right-bank landslide slope with a stepped surface. Its height is 80 m; the slope steepness -15-16o. The authors should assess the risk of landslides and recommend anti-landslide measures to ensure the safety of the future bridge. For this landslide factors have been analyzed, slope stability assessment has been performed and recommendations have been suggested. The role of the following factors have been analyzed: 1) hydrologic - erosion and abrasion reservoir and runoff role; 2) lithologyc (the presence of Urzhum and Northern Dvina horizons of plastically deformable rocks, displacement areas); 3) hydrogeological (the role of perched, ground and interstratal water); 4) geomorphological (presence of the elemental composition of sliding systems and their structure in the relief); 5) exogeodynamic (cycles and stages of landslide systems development, mechanisms and relationship between landslide tiers of different generations and blocks contained in tiers). As a result 6-7 computational models at each of the three engineering-geological sections were made. The stability was evaluated by the method “of the leaning slope”. It is proved that the slope is in a very stable state and requires the following measures: 1) unloading (truncation) of active heads blocks of landslide tiers) and the edge of the plateau, 2) regulation of the surface and groundwater flow, 3) concrete dam, if necessary.

Abstract Background Pakistan is among a number of countries facing protracted challenges in addressing maternal mortality with a concomitant weak healthcare system complexed with inequities. Sexual and reproductive health and rights (SRHR) self-care interventions offer the best solution for improving access to quality healthcare services with efficiency and economy. This manuscript documents country experience in introducing and scaling up two selected SRHR self-care interventions. A prospective qualitative study design was used and a semi-structured questionnaire was shared with identified SRHR private sector partners selected through convenience and purposive sampling. The two interventions include the use of misoprostol for postpartum hemorrhage and the use of subcutaneous depomedroxyprogesterone acetate (DMPA) as injectable contraceptive method. Data collection was done through emails and telephone follow-up calls. Results Nine of the 13 partners consulted for the study responded. The two selected self-care interventions are mainly supported by private sector partners (national and international nongovernmental organizations) having national or subnational existence. Their mandates include all relevant areas, such as policy advocacy, field implementation, trainings, supervision and monitoring. A majority of partners reported experience related to the use of misoprostol; it was introduced more than a decade ago, is registered and is procured by both public and private sectors. Subcutaneous DMPA is a new intervention, having been introduced only recently, and commodity availability remains a challenge. It is being delivered through health workers/providers and is not promoted as a self-administered contraceptive. Community engagement and awareness raising is reported as an essential element of successful field implementation; however, no beneficiary data was collected for the study. Training approaches differ considerably, are standalone or integrated with SRHR topics and their duration varies between 1 and 5 days, covering a range of cadres. Conclusion Pubic sector ownership and patronage is essential for introducing and scaling up self-care interventions as a measure to support the healthcare system in delivering quality sexual and reproductive health services. Supervision, monitoring and reporting are areas requiring further support, as well as the leadership and governance role of the public sector. Standardization of trainings, community awareness, supervision, monitoring and reporting are required together with integration of self-care in routine capacity building activities (pre- and in-service) on sexual and reproductive health in the country.

This commentary interrogates what it means for routine urban behaviours to now be replicating themselves computationally. The emergence of autonomous or artificial intelligence points to the powerful role of big data in the city, as increasingly powerful computational models are now capable of replicating and reproducing existing spatial patterns and activities. I discuss these emergent urban systems of learned or trained intelligence as being at once radical and routine. Just as the material and behavioural conditions that give rise to urban big data demand attention, so do the generative design principles of data-driven models of urban behaviour, as they are increasingly put to use in the production of replicable, autonomous urban futures.

This essay provides a brief introduction to this special issue focused on the life and work of Black Brazilian scholar-activist Abdias Nascimento. The contributors include, Vera Lucia Benedito, Ollie Johnson, Zachary Morgan, Elisa Larkin Nascimento, and Cheryl Sterling who all participated in a 2015 conference at Africana Studies at Brown University. This group of scholars aptly illustrate that Nascimento had long contributed to the internationalization of Black Studies as a field in US academe and he was crucial in establishing Brazil as a central component of the Black World. The essays have much to teach us about Nascimento’s views on the relationship between art and politics, the role of military service in shaping his activism, the significance of black politicians in the reconceptualization of Brazilian democracy, and the importance of preserving archives and expanding our understanding of the Black radical tradition.
