In this paper we consider a rich vehicle routing problem where transportation requests are characterised by multiple pickup and delivery locations. The problem is a combined load acceptance and generalised vehicle routing problem incorporating a diversity of practical complexities. Among those are time window restrictions, a heterogeneous vehicle fleet with different travel times, travel costs and capacity, multi-dimensional capacity constraints, order/vehicle compatibility constraints, and different start and end locations for vehicles. We propose iterative improvement approaches based on Large Neighborhood Search and a relatedness measure for transportation requests with multiple pickup and delivery locations. Our algorithms are characterised by very fast response times and thus, can be used within dynamic routing systems where input data can change at any time.

Many studies have focused on the societal implication of the emergence of Web 2.0. However, only a few researches have focused on the interrelationship of social media and surveillance. This thesis specifically examines the role of Facebook in community engagement on neighborhood surveillance. using a locality in Malmö municipal, Kirseberg area,  the study aimed to determine the role of the community Facebook group, its affordances, and contributions towards community engagement for neighborhood watch. Through interviews of stakeholders, observations of posts on the Kirseberg Facebook group, and a community-based participatory workshop of the residents in Kirseberg, Malmö, the study engaged 14 residents and stakeholders using data visualization as prototype artifacts to engage participants and elicit responses for data gathering. The data gathered was analysed based on thematic recognition of the study's objectives. The results indicated that many residents interact with features and tools on the Facebook group to initiate the affordances capabilities of Facebook on information relating to neighborhood surveillance.  It also noted that Facebook is a precursor and initial engagement point towards collective community action on neighborhood watch.  The thesis concludes that Facebook, as a part of the Web 2.0 platform, with strict moderation, has the inherent tools that could create affordances in different levels of interactions for the specific purpose of information, communication, engagements, and conversations towards community mobilization, building, and engagement for neighborhood watch and surveillance. The study, however, suggested further research of this phenomenon with more extensive coverage of areas in Malmö and expansion of stakeholders with an expansive methodology.

Denna studie har för avsikt att undersöka begreppet platsidentitet i relation till vad personer boende i Fellingsbro förknippar med sina liv. Syftet med studien är att undersöka vad personer i Fellingsbro förknippar med sina liv ur ett nutida och historiskt perspektiv samt om, och i så fall hur, personernas platsidentiteter har förändrats mellan 1970-talet till idag 2021.Begreppet platsidentitet har många olika definitioner. Platsidentitet kan förstås som dels baserad på platsens identitet, dels baserad på personernas identitet kopplat till platsen. Den här studien utgår från personers identitet kopplat till platsen men definitionen har även fått en egen prägel för att passa just den här studien. Det är vad personer förknippar och har förknippat med sitt liv, och därmed deras identitet i Fellingsbro, som är fokus i den här studien.Studiens empiriska undersökning är baserad på en flermetodsforskning där kvantitativa enkäter och kvalitativa intervjuer har kompletterat varandra. Enkätundersökningen låg till grund för avgränsningar i studien och intervjuerna gav fördjupad information om de olika teman som uppstod genom enkäten.Vidare är studiens slutsatser att de respondenter som har deltagit i denna studie har annorlunda platsidentiteter idag i jämförelse med vad de hade under 1970-talet. Respondenternas förändrade identiteter kan förstås genom ortens fysiska förändring, rörelsemönster och känsla för platsen. Dessa förändringar mynnar ut i att en majoritet av respondenterna idag ser andra orter som mer viktiga i sina liv än vad de var på 1970-talet. Samtidigt som respondenterna idag associerar sammanhållningen i Fellingsbro med de närmsta grannarna snarare än med Fellingsbro i stort som de i högre grad gjorde under 1970-talet.

Community and its ties to locality have been bothering sociologists and researchers since society has abandoned its traditional organization. Many of them considered positive and negative aspects of industrial and later modern society's influence on community sense and human relationships. This thesis will walk the reader through the influential writings on the topic of community, meaning of space and human relationships. Starting with the appreciation of traditional community, through worries about its disappearance, diminishing importance of local ties and ending with complete anonymity and individualization. The empirical part of this thesis brings up results of the research conducted in neighborhoods of Žiar nad Hronom, town in central Slovakia. Findings from the interviews were confronted with ideas of New Urbanism, basically confirming role of architecture design in neighbors' relationships. Intensity, frequency and quality of interaction among neighbors are thus influenced by factors of spatial design, length of residence and busyness of residents. Nature of the relationships among neighbors is far from ideal (as in traditional community) but people look for communities in wider sense, creating networks with people from other social circles than those bounded to a place.

Indiana University-Purdue University Indianapolis (IUPUI) / I present this thesis in two parts. The first is composed of a 35:41-minute documentary film entitled In the Crosshairs: how systemic racism compelled interstate development through Black neighborhoods. Accompanying it is this written essay that outlines my position and provides citations linking evidence to argument. Each component serves a different master. While the essay is intended for an academic reader, the film is intended for a general audience. Each component advances the argument. As a result of systemic racism, minority neighborhoods in Indianapolis have been devalued over time and, therefore, their residents have been left disproportionally vulnerable to displacement from federal interstate highway construction. They were vulnerable because their property was assessed as less valuable than surrounding land. Also, they lacked the political clout to resist “urban development”. Furthermore, their vulnerability was socially constructed. It never occurred to me that my place in society was arranged to my advantage. I didn’t feel advantaged in any way. Everybody I knew was like me or better than me, it seemed. As I matured, I learned that history is subjective and my world is only a small slice of history. I had never considered my whiteness an advantage. In truth, my situation has been shaped by a myriad of forces that were socially constructed. I discovered that the definition of “white” is fluid but, throughout history, has had an enormous impact on how people are treated. The following is a deep dive into what I discovered when I examined only one aspect of how race impacted the advantages I enjoyed simply because my parents were deemed sufficiently “white.”

Indiana University-Purdue University Indianapolis (IUPUI) / The Butler-Tarkington Neighborhood Association (BTNA) is a community group organized in 1956 by a few concerned couples living in the Butler-Tarkington neighborhood on the north side of Indianapolis. These couples, both Black and white, witnessed a demographic change in their community as their white neighbors fled for the suburbs as the black population expanded. The BTNA, inspired to create an organization that would promote residential integration rather than continued segregation, worked to educate neighbors on the realities of integration, promote neighborhood conversation and comradery, and worked to influence the local and state governments on the impact of segregation that harmed their community. One of the first neighborhood organizations of its kind in the country, the BTNA still exists today, but little is known about their early history. This paper looks at the BTNA’s efforts to promote residential segregation in their community through activism, conversation, and legislative change. Additionally, this paper analyzes the BTNA success in its efforts to integrate the community during their first decade of existence.

A (closed) neighborhood-restricted [≤2]-coloring of a graph G is an assignment of colors to the vertices of G such that no more than two colors are assigned in any closed neighborhood, that is, for every vertex v in G, the vertex v and its neighbors are in at most two different color classes. The [≤2]-achromatic number is defined as the maximum number of colors in any [≤2]-coloring of G. We study the [≤2]-achromatic number. In particular, we improve a known upper bound and characterize the extremal graphs for some other known bounds.
