TL;DR: It is proved that whenever the set of alternatives relative to which exhaustification takes place is semantically closed under conjunction, the two operators are necessarily equivalent.
Abstract: In this paper, I investigate the formal relationships between two types of exhaustivity operators that have been discussed in the literature, one based on minimal worlds/models, noted exh-mw (van Rooij & Schulz 2004, Schulz & van Rooij 2006, Spector 2003, 2006, with roots in Szabolcsi 1983, Groenendijk & Stokhof 1984), and one based on the notion of innocent exclusion, noted exh-ie (Fox 2007). Among others, I prove that whenever the set of alternatives relative to which exhaustification takes place is semantically closed under conjunction, the two operators are necessarily equivalent. Together with other results, this provides a method to simplify, in some cases, the computation associated with exh-ie, and, in particular, to drastically reduce the number of alternatives to be considered.
Besides their practical relevance, these results clarify the formal relationships between both types of operators.

TL;DR: In this article, the authors introduce flexibility in the provision of services in these formal relationships with adequate protection for all of the involved parties in the collaborative economy platforms, and propose a framework to provide flexible and flexible services in the formal relationships.
Abstract: The rise of the collaborative economy platforms reveals that policymakers need to start thinking about how to introduce flexibility in the provision of services in these formal relationships with adequate protection for all of the involved parties.

TL;DR: An SNA conceptual framework is proposed to analyse project processes and their variability as a consequence of BIM implementation and three types of networks are considered as suitable for the implementation of the method.
Abstract: Increasing complexity in construction projects requires intensive research for their performance analysis. Implementation of informatics and Building Information Modelling (BIM) further affect project performance. Construction management processes can be analysed and assessed effectively through interdependence with their administrators and other users. In this literature review, we propose actors and relations interdependence to be examined under the lenses of Social Network Analysis (SNA) theory. Three types of networks are considered as suitable for the implementation of the method, namely, formal relationships through contractual arrangements; informal communication relationships and the relevant changes on roles and relations based on the implementation of BIM. Attributes are assigned to roles and relations are structured through variables. This research purposes an SNA conceptual framework to analyse project processes and their variability as a consequence of BIM implementation.

TL;DR: It is found that over time SPS contracts have been modified to better establish inter-institutional relationships in compliance with guidelines regarding the allocation of funds and the purchasing of services, but they still need further improvements to accomplish their role of increasing efficiency in the flow of funds through the Mexican health system.
Abstract: —The introduction of Seguro Popular de Salud (SPS) expanded the practice of contracting in the Mexican health system. Specifically, SPS established that formal relationships among instituti...

TL;DR: Ambo et al. as discussed by the authors examined contemporary relationships between American Indians and public postsecondary universities in California and found that formal relationships focused on federally recognized tribes and were dictated by federal, state or systemwide policies, educational resources, and economic opportunities.
Abstract: Author(s): Ambo, Theresa J. | Advisor(s): Hurtado, Sylvia | Abstract: There is an educational attainment crisis among American Indian students in California’s public colleges and universities, who continue to have the lowest college completion compared to any underrepresented group. California tribes believe that higher education can assist in the achievement of nation-building goals. However, close examination of how tribes and postsecondary institutions work together to ensure the success of American Indian students and their communities is necessary. This study examined contemporary relationships between tribal nations and public postsecondary universities in California. This nested, multiple case study used Tribal Critical Race Theory and community-campus partnership frameworks to understand how institutional agents articulate formal and informal relationships with local tribes. Case study sites consisted of two University of California campuses, non-federally recognized tribes, and proximally located federally recognized tribes. Documents and interviews with senior administrators, American Indian unit heads, and tribal representatives were collected and analyzed to understand different perspectives on relationships with, responsibility to, and educational needs of tribes within and across sites. Several findings emerged related to the limited knowledge university administrators had regarding American Indians broadly and the state of relations with California tribes. Findings demonstrate that formal relationships focused on federally recognized tribes and were dictated by federal, state or system-wide policies, educational resources, and economic opportunities. Conversely, informal relationships with non-federally recognized tribes were primarily maintained by university-based American Indian programs or departments. Representatives from American Indian units expressed the responsibility of universities to include and serve American Indian students and communities for democratic, reconciliatory, and ethical reasons. Last, participants identified current tribal needs for academic preparation, educational resources to support nation-building, and assistance with federal recognition applications, but also stressed the importance of consulting with tribes to address evolving needs. Overall, this study offers significant recommendations for the case study sites, as well as public universities in California and nationally. From a substantive standpoint, this analysis adds to our understanding of factors that are important to advancing tribal-university relationships and partnerships. This study also expands on existing community-campus partnership frameworks, introducing a cultural-specific approach for incorporating tribes into university government and community relations activities.
