Research Doctorate - Doctor of Philosophy (PhD) / The present work is a project in social psychology that looks at four different types of ingroup identification and investigates their possible variations as a function of defining personal characteristics and group-related phenomena. Five studies provide evidence for the validity of a qualitative distinction between centrality, social, communal, and interdependent identification and examine the way in which culture, gender, group status, relationship attachment style, and group type predicted each type of identification with groups. The research employs a multi-sample approach and combines correlational, experimental, and quasi-experimental designs. Research data was collected using purpose-built questionnaires that included a newly constructed Centrality, Social, Communal and Interdependent Identification Scale (CSCIIS) together with previously validated measures. Participants from Western and non-Western cultural backgrounds showed dispositional differences in their preferred type of identification, and differed in the extent to which their identification was focused on the group as a whole or on the individual group members. The studies integrate social identity theory, self-construal, and behavioural interdependence ideas, suggesting that there are some types of ingroup identification that are primarily based on interpersonal processes and relationships between group members. The leading themes are those of the conceptual complexity in assessing individuals’ identification with various social groups and the possibilities for deepening our understanding of the phenomenon by considering the key aspects that separate one type of ingroup identification from another. The results help bring clarity to a confusing literature dealing with ingroup identification and illustrate the value of a different level approach in the area.

Poverty and food insecurity are common problems among low-income households in developing countries. Innovative interventions in the agricultural sector are regarded as effective in poverty alleviation and therefore food insecurity. Food insecurity is defined by London and Anupindi (2012) as a lack of access to adequate, safe and nutritious food and is closely associated with poverty. It can ultimately be addressed as part of a broader strategy to alleviate poverty, which would include enterprise-led initiatives, inclusive approaches and value chain adjustments. London and Anuipindi (2012) argued that a study hoping to demonstrate the relevance and reliability of understanding the base of pyramid (BoP) as a catalyst to interdependence–based collaboration, would address the level of agribusiness isolation and individualism, to reap the benefits of shared advantage, followed by addressing the interconnected issues of poverty and food insecurity. This study proposes that small scale farmers can benefit from interdependence-based collaborations (IBC) of key role players from the state, private sector and civil society. Consequently, this is a qualitative exploratory study, aiming to seek new insights into the application of inclusive models based on the IBC within the small farm holding, the private sector, civil society and government, and thus their impact on the capacitation of the small-scale farmer and alleviation of poverty. / Dissertation (MBA)--University of Pretoria, 2013. / ccgibs2014 / Gordon Institute of Business Science (GIBS) / MBA / Unrestricted

abstract: Food-sharing is central to the human experience, involving biological and sociocultural functions. In small-scale societies, sharing food reduces variance in daily food-consumption, allowing effective risk-management, and creating networks of interdependence. It was hypothesized that trust and interdependence would be fostered between people who shared food. Recruiting 221 participants (51% Female, Mage = 19.31), sharing food was found to decrease trust and interdependence in a Trust Game with $3.00 and a Dictator Game with chocolates. Participants trusted the least and gave the fewest chocolates when sharing food. Contrary to lay beliefs about sharing food, breaking bread with strangers may hinder rather than foster trust and giving in situations where competition over limited resources is salient, or under one-shot scenarios where people are unlikely to see each other again in the future. / Dissertation/Thesis / Masters Thesis Psychology 2020

Since Woodrow Wilson's (1885) analysis of Congress, researchers assumed that members of Congress look to one another for information, cues, and advice on unfamiliar policy areas. The amount of time and effort that each legislator and their staffers would have to put in to make all of these voting decisions would be insurmountable. Fellow legislators are a resource to turn to for guidance or assistance. Legislators are able to influence their colleagues above and beyond each of their individual preferences. The members of Congress that are most influential will not necessarily be the same for every bill. The significant legislators may be one's co-partisans and the party leadership or they may be a group of legislators with whom they share a common interest. Spatial analysis allows researchers to look more explicitly at the relationships between legislators and their colleagues. I use spatial probit and a spatial duration model to study these issues by examining the factors that influence voting decisions and the timing of position announcements. I look at a variety of different policy areas, including foreign policy, education, and agriculture, over an extensive time period (1933-2014) to test which relationships are most influential on their decisions. I study the interdependence between three different relationships, same party, state delegation, and ideological similarity, and hypothesize that these ties will lead legislators to behave more similarly. The use of the spatial analysis provides an opportunity to test these relationships and see if even after controlling for other influences there is dependence between legislators. In my research, I find that legislators are interdependent regardless of their individual characteristics. When I analyze voting behavior, legislators' behave similarly from one another across all three relationships above and beyond what we would expect given their personal preferences. These positive findings do not hold when I study the timing of position announcements where legislators behave dissimilarly from one another when interdependence exists. The study, overall, suggests that legislative ties are especially important in explaining voting behavior and that it is critical to account for these relationships.

This study empirically examines the dynamics and conditions of conflict managing approaches on government and business collaboration. It posits that conflict for mutual benefit critically effects government and business collaboration outcomes. This study adopts Deutsch’s (1973) theory of goal interdependence to understand when and how government officials and business managers adopt the mutually beneficial conflict approach. It proposes that cooperative goals between government officials and business managers promote the mutually beneficial conflict approach and reduce win-lose competitive conflict and avoiding conflict. A total of 101 interviews were conducted in China in 2009. Results of structural equation modeling and other analyses support several of hypotheses as well the proposed theoretical model that goal interdependence affects different conflict approaches (conflict for mutual benefit, win-lose competitive conflict and avoiding conflict) that in turn influence government and business collaboration outcomes, specifically task accomplishment, future collaboration and public interest. It identifies that conflict for mutual benefit approach taken by government officials and business managers can promote task accomplishment, future collaboration and public interest. Path estimates show that avoiding conflict can undermine task accomplishment and public interest. But results indicate that win-lose competitive conflict approach does not necessarily undermine task accomplishment, future collaboration, and the public interest as expected. Findings suggest important practical implications that government officials and business managers can improve their collaboration in China by strengthening their cooperative goals and discussing conflicts for mutual benefit. The study contributes to the conflict management literature as well as the generalization of goal interdependence theory.

The possibility of opportunistic behavior is an important barrier to the collaboration between partners in the supply chain as partners pursue their self-interests with guile. Opportunistic behavior threatens the partners’ relationships, influences their work accomplishment and prevents future collaboration. This study hypothesizes that opportunism is not just the result of people’s self-interests pursuit but depends on how they think their self-interests are related. Opportunism in organizational partnerships could be understood in terms of how partners perceive their goals are related to each other. When partners believe that their goals are competitively or dependently rather than cooperatively related, they are more likely to pursue their self-interests opportunistically. Altogether 86 face-to-face interviews were carried out in Beijing, Nanchang and Guangzhou, China to explore the links and relations among goal interdependencies, opportunism and the outcomes. Participants who work in a supply chain partnership were asked to describe an incident regarding their collaboration with their partners. It included the people involved, the reasons, what occurred, and the consequences. Structural equation modeling explored the proposed model that goal interdependencies could affect the levels of opportunism and thus influence the partnerships. Results suggest that cooperative goals are important foundations for effective organizational partnerships.

This dissertation is an effort to understand the processes and systems housed within the infrastructure of a dynamic urban environment. Jeppestown, or Jeppe, as it is known by its inhabitants, is a post-industrial wasteland on the eastern outskirts of Johannesburg CBD (central business district). This rich cultural landscape was formed over generations by optimistic prospectors intrigued by the illusion of riches posed by the City of Gold. The project is focused on linking and transforming voids within the urban fabric, which are threatened by gentrification, into a healthy and productive network of public space. Guided by mapping and observation techniques, the designer can formulate the conception for a landscape architectural intervention aimed at maintaining and amplifying certain aspects coinciding with the ritualistic activities of everyday life as established within Jeppestown. Anchored by a series of social and economic nodes, a spinal development emerges, addressing thresholds between public and private realms by investigating edges as vessels for environmental and social systems. The designer uses a combination of existing characteristics of this urban artefact and newly introduced sustainable design principles to carve a coherent and productive public environment from an amalgamated entity termed the landscape slate. / Dissertation (ML(Prof))--University of Pretoria, 2014. / Architecture / ML(Prof) / Unrestricted

According to the United Nations, by the year of 2050, 16% ofthe world’s population will be over the age of 65, that is one in six people.¹ Considering this, there is more need than ever to bridge the generation gap. Prior research on the theme of different kinds of domestic efficiency, led me to a comparative study between mass produced housing and collective living. I spoke in favour of the values of social sustainability at the price of economically superior construction methods. Departing then from the subject of social isolation and involuntary loneliness versus togetherness, I landed on the topic of elderly care and intergenerational interdependence. This paper proposes the need of intergenerational housing and therefore my method for approaching this theme is through designing a combined elderly care home, student housing and preschool. My findings suggest that the environment which surrounds us impacts us in a number of ways, as does the ambiance, the people, and the relationships we have with them. Therefore, I aim to create a space with a warm and familiar feel as opposed to an impersonal and institutional one and a place where relationships between different age groups can naturally blossom.

Multiple related software development projects are often managed concurrently and systematically to deliver a complex software system. This approach of managing multiple interdependent projects together to achieve a common goal is called program management (Pellegrinelli, 1997). A software development program can generate the benefits that cannot be achieved by managing projects individually. The software product development program has the special characteristics such as complexity, uncertainty and interdependence (1995). A software product development program can play an active role in managing the uncertainty and interdependence in the software development process. This dissertation is designed to examine the external communication effectiveness of the program team on the interdependence between the program and the larger organizational context. In addition, this dissertation studies the inter-project coordination effectiveness on uncertainty within a program. Based upon organizational Information Processing Theory (IPT) and Resource Dependence Theory (RDT), theoretical frameworks are developed. The proposed research models are tested by surveying software product development programs across a range of industries. The results will contribute to the understanding of multiple-project communication in a program's context. The specific interactions between coordination/communication and the product development characteristics will provide a guideline for the industrial practices.

This research examines how the harvesting behavior of nonindustrial private forest landowners, and their use of forestland for non-timber amenities, is affected by adjacent landowner behavior. The uncertainty an individual landowner has regarding adjacent landowners' preferences, and how the production of non-timber amenities on their own stands relies on the condition of adjacent stocks, is specifically addressed. Economic characterizations of substitutes and complements are employed to investigate the differences in optimal stock levels at the steady state in the production of amenities under various levels of cooperation among landowners. It is shown that there are externalities present when landowners do not coordinate management actions when parcels are spatially interdependent. The effects of spatial interdependencies on landowner behavior are further explored using data from a survey of forest landowners in Central Virginia. Findings suggest that forest landowners are willing to coordinate activities, and such decisions are determined by similar characteristics that function in predicting landowner behavior regarding timber harvesting. Further, landowners' decisions to use own and adjacent parcels were correlated, hinting at the spatial interdependencies of stocks in amenity valuations. Both the theoretical and empirical analyses suggest that the lack of coordination among landowners and its effects on stock management would be best addressed through the use of incentives to drive spatially efficient outcomes. / Ph.
