Abstract:
ABSTRACT Cohesion of Myxococcus xanthus cells involves interaction of a cell surface cohesin with a component of the extracellular matrix. In this work, two previously isolated cohesion-defective (fbd) mutants were characterized. The fbdA and fbdB genes do not encode the cohesins but are necessary for their production. Both mutants produce type IV pili, suggesting that PilA is not a major cohesin.

Abstract:
The tethering together of sister chromatids by the cohesin complex ensures their accurate alignment and segregation during cell division. In vertebrates, sister chromatid cohesion requires the activity of the ESCO2 acetyltransferase, which modifies the Smc3 subunit of cohesin. It was shown recently that ESCO2 promotes cohesion through interaction with the MCM replicative helicase. However, ESCO2 does not significantly colocalize with the MCM complex, suggesting there are additional interactions important for ESCO2 function. Here we show that ESCO2 is recruited to replication factories, sites of DNA replication, through interaction with PCNA. We show that ESCO2 contains multiple PCNA-interaction motifs in its N terminus, each of which is essential to its ability to establish cohesion. We propose that multiple PCNA-interaction motifs embedded in a largely flexible and disordered region of the protein underlie the unique ability of ESCO2 to establish cohesion between sister chromatids precisely as they are born during DNA replication.

Abstract:
Sister chromatid separation at anaphase is triggered by cleavage of the cohesin subunit Scc1, which is mediated by separase. Centriole disengagement also requires separase. This dual role of separase permits concurrent control of these events for accurate metaphase to anaphase transition. Although the molecular mechanism underlying sister chromatid cohesion has been clarified, that of centriole cohesion is poorly understood. In this study, we show that Akt kinase–interacting protein 1 (Aki1) localizes to centrosomes and regulates centriole cohesion. Aki1 depletion causes formation of multipolar spindles accompanied by centriole splitting, which is separase dependent. We also show that cohesin subunits localize to centrosomes and that centrosomal Scc1 is cleaved by separase coincidentally with chromatin Scc1, suggesting a role of Scc1 as a connector of centrioles as well as sister chromatids. Interestingly, Scc1 depletion strongly induces centriole splitting. Furthermore, Aki1 interacts with cohesin in centrosomes, and this interaction is required for centriole cohesion. We demonstrate that centrosome-associated Aki1 and cohesin play pivotal roles in preventing premature cleavage in centriole cohesion.

Abstract:
The ring-shaped cohesin complex topologically entraps chromosomes and regulates chromosome segregation, transcription, and DNA repair. The cohesin core consists of the structural maintenance of chromosomes 1 and 3 (Smc1–Smc3) heterodimeric ATPase, the kleisin subunit sister chromatid cohesion 1 (Scc1) that links the two ATPase heads, and the Scc1-bound adaptor protein Scc3. The sister chromatid cohesion 2 and 4 (Scc2–Scc4) complex loads cohesin onto chromosomes. Mutations of cohesin and its regulators, including Scc2, cause human developmental diseases termed cohesinopathy. Here, we report the crystal structure of Chaetomium thermophilum (Ct) Scc2 and examine its interaction with cohesin. Similar to Scc3 and another Scc1-interacting cohesin regulator, precocious dissociation of sisters 5 (Pds5), Scc2 consists mostly of helical repeats that fold into a hook-shaped structure. Scc2 binds to Scc1 through an N-terminal region of Scc1 that overlaps with its Pds5-binding region. Many cohesinopathy mutations target conserved residues in Scc2 and diminish Ct Scc2 binding to Ct Scc1. Pds5 binding to Scc1 weakens the Scc2–Scc1 interaction. Our study defines a functionally important interaction between the kleisin subunit of cohesin and the hook of Scc2. Through competing with Scc2 for Scc1 binding, Pds5 might contribute to the release of Scc2 from loaded cohesin, freeing Scc2 for additional rounds of loading.

Abstract:
At anaphase onset, Sgo1 function of cohesion protection must be disabled to allow timely chromosome segregation, but how this is achieved is not fully understood. Here, we show that SET, a known PP2A inhibitor, directly binds to a domain in Sgo1 in close proximity to the cohesin-binding motif. The Sgo1–cohesin binding can be disrupted by SET in a dose-dependent manner in vitro as well as by SET overexpression in cells, suggesting that SET is also an inhibitor to the Sgo1–cohesin binding. Furthermore, the SET binding–deficient Sgo1 mutant fully supports centromeric cohesion protection but delays chromosome segregation, suggesting that the SET–Sgo1 binding is required for timely chromosome segregation. Moreover, overexpression of SET WT, not the Sgo1 binding–deficient mutant, exacerbates the occurrence of cohesion fatigue in MG132-arrested cells. Conversely, SET depletion delays it. Thus, we propose that a major function of SET during mitosis is to disrupt the Sgo1–cohesin interaction, thereby promoting centromeric cohesion de-protection and timely chromosome segregation at anaphase onset.

Abstract:
Cohesin is an essential protein complex required for sister chromatid cohesion. Cohesin associates with chromosomes and establishes sister chromatid cohesion during interphase. During metaphase, a small amount of cohesin remains at the chromosome-pairing domain, mainly at the centromeres, whereas the majority of cohesin resides in the cytoplasm, where its functions remain unclear. We describe the mitosis-specific recruitment of cohesin to the spindle poles through its association with centrosomes and interaction with nuclear mitotic apparatus protein (NuMA). Overexpression of NuMA enhances cohesin accumulation at spindle poles. Although transient cohesin depletion does not lead to visible impairment of normal spindle formation, recovery from nocodazole-induced spindle disruption was significantly impaired. Importantly, selective blocking of cohesin localization to centromeres, which disrupts centromeric sister chromatid cohesion, had no effect on this spindle reassembly process, clearly separating the roles of cohesin at kinetochores and spindle poles. In vitro, chromosome-independent spindle assembly using mitotic extracts was compromised by cohesin depletion, and it was rescued by addition of cohesin that was isolated from mitotic, but not S phase, cells. The combined results identify a novel spindle-associated role for human cohesin during mitosis, in addition to its function at the centromere/kinetochore regions.

Online, virtual group interactions may help adherence to health promotion programs. The purpose of this study was to explore longitudinal relationships among dimensions of group cohesion and group-interaction variables to inform and improve group-based strategies within programs aimed at promoting physical activity in virtual communities. In all, 56 online virtual users completed a group dynamics–based physical activity promotion intervention and assessments of group cohesion and group interaction at baseline and 4 weeks. Friendly competition and cooperation were consistently strong predictors of cohesion. Facilitating a sense of friendly competition and cooperation may increase engagement in physical activity programs by bolstering group cohesion.

Abstract:
The inner centromere region of a mitotic chromosome critically regulates sister chromatid cohesion and kinetochore–microtubule attachments. However, the molecular mechanism underlying inner centromere assembly remains elusive. Here, using CRISPR/Cas9-based gene editing in HeLa cells, we disrupted the interaction of Shugoshin 1 (Sgo1) with histone H2A phosphorylated on Thr-120 (H2ApT120) to selectively release Sgo1 from mitotic centromeres. Interestingly, cells expressing the H2ApT120-binding defective mutant of Sgo1 have an elevated rate of chromosome missegregation accompanied by weakened centromeric cohesion and decreased centromere accumulation of the chromosomal passenger complex (CPC), an integral part of the inner centromere and a key player in the correction of erroneous kinetochore–microtubule attachments. When artificially tethered to centromeres, a Sgo1 mutant defective in binding protein phosphatase 2A (PP2A) is not able to support proper centromeric cohesion and CPC accumulation, indicating that the Sgo1–PP2A interaction is essential for the integrity of mitotic centromeres. We further provide evidence indicating that Sgo1 protects centromeric cohesin to create a binding site for the histone H3–associated protein kinase Haspin, which not only inhibits the cohesin release factor Wapl and thereby strengthens centromeric cohesion but also phosphorylates histone H3 at Thr-3 to position CPC at inner centromeres. Taken together, our findings reveal a positive feedback–based mechanism that ensures proper assembly of the functional inner centromere during mitosis. They further suggest a causal link between centromeric cohesion defects and chromosomal instability in cancer cells.

Abstract:
The purpose of this dissertation was to explore, through a social ecological framework, the multifaceted effects of the neighborhood environment by investigating how dimensions of both the built environment and the neighborhood social context may interact to influence walking. Aesthetics, land use mix, crime, and pedestrian infrastructure were considered with respect to built environment walkability, and the neighborhood social context was conceptualized using measures of both social cohesion and social interaction with neighbors. This research used data from an Environmental Protection Agency (EPA)-funded study of 748 adults (18 years of age and older) residing in the Lents neighborhood in Portland, Oregon. Through a series of both multiple linear and logistic regression models, the analyses examined the specific pathways by which social interaction with neighbors, social cohesion, and age influenced the relationship between the built environment and walking behavior. Results suggest that both social interaction and social cohesion but not age moderate the effects of the built environment on walking. There was evidence of mediation, as well, for both social interaction and social cohesion. The implications of these findings for future research and policy are discussed.

Abstract:
Background: Physical inactivity of the general population is a major public health concern in the US and around the world. Community-based interventions that include evidence-based principles of group dynamics are effective at improving individual-level physical activity behaviors as well as changing social norms for health behaviors. The use of technologies such as smartwatches has a potential to channel and amplify underlying group dynamics principles in such interventions. In order to explore the use of smartwatches for group dynamics-based physical activity interventions, a smartwatch centered system was designed and deployed as part of an eight-week pilot study. Objectives: The primary goal of this study was to explore the degree to which smartwatches effectively channel group dynamics strategies in the context of an eight-week community based physical activity intervention. Methods: In this explanatory mixed-methods study, system usage data were analyzed (e.g., frequency of interaction with smartwatch and smartphone) and participant physical activity (e.g., participant steps tracked by the system). To provide a richer picture of the user experience, use of features, and impact of group dynamics, participants were invited to participate in one-on-one interviews after the pilot program. The group dynamics-based questions centered on the individual’s attraction to the group task and socially as well as the individual’s perception of group integration around the task and as a social unit (i.e., the four dimensions of cohesion). The interview recordings were transcribed verbatim and analyzed via an abbreviated grounded theory approach. The system usage data was visually and numerically summarized. Results: Five of the seven participants completed interviews. The interview analysis resulted in 365 meaning units representing 2 themes (related to user experience with devices and manifestations of group dynamic principles), 4 sub-themes and 23 categories. The participants completed 31.3 (SD=2.91) miles per week and engaged with the smartwatch and the Android app 2.6 and 1.5 times a day, respectively. Analysis of interviews and the system usage logs from five participants, reveal sustained engagement with the smartwatch and the smartphone app. The system facilitated self-reflection and awareness in terms of physical activity levels, encouraged interactions with the team members and helped them to stay aware of the daily goals. Additionally, the participants reported habit formation in terms of wearing and using the smartwatch on the daily basis. Implications: This study provides preliminary support that accessible information via the custom smartwatch watchface can be a viable solution for retaining higher participant engagement during group dynamics-based community interventions. Such devices can help expand group-dynamics interventions by making them less depended on in-person delivery methods.

Abstract:
Virtual teams in industry are increasingly being used to develop software, create products, and accomplish tasks. However, analyzing those collaborations under same-time/different-place conditions is well-known to be difficult. In order to overcome some of these challenges, this research was concerned with the study of collaboration-based, content-based and temporal measures and their ability to predict cohesion within global software development projects. Messages were collected from three software development projects that involved students from two different countries. The similarities and quantities of these interactions were computed and analyzed at individual and group levels. Results of interaction-based metrics showed that the collaboration variables most related to Task Cohesion were Linguistic Style Matching and Information Exchange. The study also found that Information Exchange rate and Reply rate have a significant and positive correlation to Task Cohesion, a factor used to describe participants' engagement in the global software development process. This relation was also found at the Group level. All these results suggest that metrics based on rate can be very useful for predicting cohesion in virtual groups. Similarly, content features based on communication categories were used to improve the identification of Task Cohesion levels. This model showed mixed results, since only Work similarity and Social rate were found to be correlated with Task Cohesion. This result can be explained by how a group's cohesiveness is often associated with fairness and trust, and that these two factors are often achieved by increased social and work communications. Also, at a group-level, all models were found correlated to Task Cohesion, specifically, Similarity+Rate, which suggests that models that include social and work communication categories are also good predictors of team cohesiveness. Finally, temporal interaction similarity measures were calculated to assess their prediction capabilities in a global setting. Results showed a significant negative correlation between the Pacing Rate and Task Cohesion, which suggests that frequent communications increases the cohesion between team members. The study also found a positive correlation between Coherence Similarity and Task Cohesion, which indicates the importance of establishing a rhythm within a team. In addition, the temporal models at individual and group-levels were found to be good predictors of Task Cohesion, which indicates the existence of a strong effect of frequent and rhythmic communications on cohesion related to the task. The contributions in this dissertation are three fold. 1) Novel use of Temporal measures to describe a team's rhythmic interactions, 2) Development of new, quantifiable factors for analyzing different characteristics of a team's communications, 3) Identification of interesting factors for predicting Task Cohesion levels among global teams.

ENGLISH ABSTRACT: Twenty years after the end of apartheid, South Africa remains one of the most unequal countries in the world. Socio-economic polarisation is entrenched by the lack of social capital and interactions across racial and economic divides, blocking pathways out of poverty. This dissertation examines social mobility and cohesion in post-apartheid South Africa by considering three related topics. Chapter 2 of the dissertation examines the impact of school quality on the academic performance of disadvantaged learners as one of the most important enforcing factors perpetuating the social and economic divides. Given the historic racial and economic stratification of the South African public school system, many black children are sent to historically white public schools as a way to escape poverty. Using longitudinal data, this chapter estimates the effect of attending a historically white school on the numeracy and literacy scores of black children. The main challenge is to address the selection bias in the estimates, for which a value-added approach is implemented in order to control for unobserved child-specific heterogeneity. In addition, various household covariates are used to control for household-level differences among children. The results indicate that the attendance of a former white school has a large and statistically significant impact on academic performance in both literacy and numeracy which translates into more than a year’s worth of learning. The main finding is robust to various robustness checks. In Chapter 3 the dissertation examines social cohesion by considering the concept of reference groups used in the evaluation of relative standing in utility functions. The chapter develops a model in which various parameters are allowed to enter the utility function without linearity constraints in order to determine the weight placed on the well-being of individuals in the same race group as the respondent versus all the other race groups living in one of three specified geographic areas. The findings suggest that reference groups have shifted away from a purely racial delineation to a more inclusive one subsequent to the country’s first democratic elections in 1994. Although most of the weight is still placed on same-race relative standing, the estimates suggest that individuals from other race groups also enter the utility function. The chapter also examines the spatial variation of reference groups and finds evidence that the relative standing of close others (such as neighbours) enter the utility function positively while individuals who live further away (strangers) enter the utility function negatively. Finally, Chapter 4 provides a summary of the dynamics of income in South Africa, using longitudinal household data. Chapter 4 is aimed at separating structural trends in income from stochastic shocks and measurement error, and makes use of an asset-based approach. It first estimates the percentage of individuals who were in chronic poverty between 2010 and 2012 and then estimates the shape of structural income dynamics in order to test for the existence of one or more dynamic equilibrium points, which would be indicative of the existence of a poverty trap. The findings do not provide any evidence for the existence of a poverty trap. In addition, contrary to earlier findings, the results do not provide evidence for the existence of an asset-based threshold at which the structural income accumulation paths of households bifurcate. Instead, the results seem to indicate the existence of a threshold beyond which structural income remains persistent with very little upward mobility. The robustness of the results is confirmed by making use of control functions in order to correct for any measurement error which may exist in the data on assets.
AFRIKAANSE OPSOMMING: Twintig jaar nadat apartheid beëindig is word Suid-Afrika steeds as een van die wêreld se mees ongelyke lande gekenmerk. Sosio-ekonomiese polarisasie word verskans deur die gebrek aan sosiale kapitaal en interaksies tussen rassegroepe en ekonomiese klasse, wat lei tot die versperring van roetes uit armoede. Hierdie proefskrif bestudeer sosiale mobiliteit en samehorigheid in post-apartheid Suid- Afrika deur middel van drie verwante onderwerpe. Hoofstuk 2 van hierdie proefskrif ondersoek die impak van skoolkwaliteit op die akademiese prestasie van benadeelde leerders as een van die belangrikste faktore wat huidige sosiale en ekonomiese skeidings afdwing. Gegewe die historiese verdeling van die openbare skoolstelsel volgens ras en ekonomiese status, word heelwat swart kinders na historiese blanke skole gestuur ten einde armoede te ontsnap. Deur gebruik te maak van paneeldata word die impak van skoolbywoning van ’n historiese blanke skool op die geletterheid van swart kinders - in beide wiskunde en Engels - beraam. Die grootste uitdaging is om enige sydigheid in die beramings aan te spreek, waarvoor daar van ’n waarde-toevoegings inslag gebruik gemaak word ten einde te kontroleer vir enige individuele heterogeniteit. ’n Verskeidenheid kontroles op die vlak van die huishouding word gebruik ten einde te kontroleer vir verskille tussen kinders uit verkillende huishoudings. Die resultate dui daarop dat bywoning van ’n historiese wit skool ’n groot en statisties beduidende impak op die akademiese prestasie van beide wiskundige asook litterêre geletterdheid het, wat omgeskakel kan word in meer as ’n jaar se leerwerk. ’n Verskeidenheid verifikasie toetse bevestig die geldigheid van die resultate. Hoofstuk 3 van die proefskrif bestudeer sosiale samehorigheid deur die samestelling van verwysingsgroepe in die evaluasie van relatiewe posisionering in nutsfunksies te oorweeg. Die hoofstuk ontwikkel ’n model waarin verskeie parameters sonder liniêre beperkings in die nutsfunksie toegelaat word ten einde die gewig te beraam wat geplaas word op die welstand van individue in dieselfde rasgroep as die respondent teenoor al die ander rasgroepe wat in een van drie gespesifiseerde geografiese areas woon. Die bevindings dui daarop dat, na die land se eerste demokratiese verkiesings in 1994, die definiering van verwysingsgroepe weggeskuif het van ’n verdeling volgens ras na ’n meer inklusiewe definisie. Alhoewel meeste van die gewig steeds geplaas word op relatiewe posisionering teenoor individue van dieselfde ras, dui die beramings daarop dat individue van ander rassegroepe ook ingesluit word in die nutsfunksie. Die hoofstuk beoordeel ook die ruimtelike variasie van verwysingsgroepe en bevind dat die relatiewe posisionering van nabye individue (soos byvoorbeeld bure) die nutsfunksie positief beïnvloed terwyl individue wat vêr weg woon (vreemdelinge) die nutsfunksie negatief beïnvloed. Hoofstuk 4 van die proefskrif sluit af met ’n opsomming van die inkomste dinamika in Suid-Afrika, deur gebruik te maak van paneelhuishoudingdata. Die laaste hoofstuk mik om die strukturele tendens in inkomste van enige stogastiese skokke en metingsfoute te isoleer en maak gebruik van ’n bate-gebasseerde inslag. Dit beraam eerstens die persentasie van individue wat in kroniese armoede verkeer het tussen 2010 en 2012 en beraam dan die vorm van die strukturele inkomste dinamika. Dit word gedoen ten einde vir die bestaan van een of meer dinamiese ekwilibrium punte te toets, wat aanduidend sou wees van die bestaan van ’n armoedestrik. Die bevindings bied nie enige bewyse vir die bestaan van ’n armoedestrik nie. Ook bied die resultate geen bewyse vir die bestaan van ’n bategebasseerde drempel waar die strukturele inkomste akkumulasieroetes van huishoudings vertak nie, in teenstelling met vorige resultate. In plaas daarvan, blyk die resultate te dui op die bestaan van ’n drempel waarna strukturele inkomste volhardend bly met baie min opwaardse mobiliteit. Die geldigheid van die resultate word bevestig deur gebruik te maak van kontrolefunksies ten einde te korrigeer vir enige metingsfoute wat moontlik in die data van bates mag bestaan.

Abstract:
Over the past fifty or so years there has been a well examined decline in socialconnections and many other facets of American communities (Fischer 1982; Putnam2000; Freeman 2001; McPherson, Smith-Lovin, & Brashears 2006; Dunham-Jones &Williamson 2009). New urbanism has been proposed as a tool to reverse some of thissocial decline in communities. This study seeks to understand the possible socialconnective benefits of new urbanism in a number of ways. First, a new urbanistcommunity is compared to a similar adjacent community that also happens to betraditional suburban community. The study examines differences between the twocommunities in terms of social connections, social interactions, and communitysatisfaction. Second, the study examines individual design elements of new urbanism to understand their relationships with social interactions and social connections. This study also examines community cohesion in terms of diverse social interactions and bridging ties. Previous studies suggest that bridging ties are more likely to be formed between persons who are connected with weaker social bonds (Granovetter, 1973) as well as persons who interact through spontaneous rather than planned forms of social interaction (Molm, Collett, & Schaefer 2007). Lastly, this study seeks to understand if any of the new urbanist design strategies examined are related to bridging ties. The findings of this study suggested that new urbanist communities do have more social interactions, social connections, and community satisfaction than do traditional suburban communities. The findings also suggested that four new urbanist design strategies: porches, community meetings, and mixed-use zoning are positively related to social interactions and social connections. Moreover, findings suggested that persons connected by weaker social bonds are indeed more likely to have bridging ties, however, they did not support the idea that persons who have more spontaneous interactions will also be more likely to have bridging ties. Lastly, the findings indicated that of all the new urbanist design strategies, only the neighborhood business center was positively related to bridging ties. Conversely, a negative relationship was found between resident's who use their porches and bridging ties.

Abstract:
Cohesive forces between grains can arise from a variety of sources – such as liquid bridge (capillary) forces, van der Waals forces, or electrostatic forces – and may play a significant role in the processing of fine and/or moist powders. While recent advances have been made in our understanding of liquid-induced cohesion at the macroscopic level, in general, it is still not possible to directly connect this macroscopic understanding of cohesion with a microscopic picture of the particle properties and interaction forces. In fact, conventional theories make no attempt to distinguish between these modes of cohesion, despite clear qualitative differences (lubrication forces in wet systems or electrostatic repulsion are two good examples). In this work, we discuss several discrete characterization tools for wet (cohesive) granular material with simple, physically relevant interpretations. We examine the utility of these tools, both computationally and experimentally, by exploring a range of cohesive strengths (from cohesionless to cohesive) in several prototypical applications of solid and gas-solid flows.
