Personal projects, affect, and need satisfaction : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in psychology, at Massey University

The present study investigated effects that patterns of purposeful human action, conceived as personal projects, have on positive and negative affect and need satisfaction. Replication was attempted of main effects reported in the literature for project attributes upon affective experience. More importantly, a more complex view of the effects of projects attributes was proposed whereby project attributes interact with each other and age and sex to influence affect. In addition, an investigation into the determinants of need satisfaction was conducted utilising both within- and between- subjects modes of analysis. Seventy respondents completed a questionnaire containing measures of positive and negative affect, a project elicitation list, and measures of the project attributes of need satisfaction, involvement, conflict, and time-frame. Regression analyses generally failed to replicate reported relationships between project attributes and positive or negative affect. In contrast, a number of significant interaction effects did emerge between project attributes and age and sex, although each of these related only to positive affect. These interactions were between involvement and age, conflict and sex, conflict and age. The determinants of need satisfaction were found to differ greatly in significance but not magnitude, according to the mode of analysis used. Need satisfaction was positively related to involvement, and engagement in long term projects, and negatively to interproject conflict. In addition to these main effects a hypothesized quadratic effect for project conflict was found and interaction between sex and conflict. The issues concerning which is the more appropriate level of analysis are discussed. It was concluded for the interaction analyses that, while project attributes may be considered as independent influences upon positive affect, they should not be considered independently of age and sex. It is concluded that projects did not adequately match expectations of relating to affect and need satisfaction and are limited in their seeming inability to account for negative affect

A general lower bound for collaborative tree exploration

We consider collaborative graph exploration with a set of $k$ agents. All agents start at a common vertex of an initially unknown graph and need to collectively visit all other vertices. We assume agents are deterministic, vertices are distinguishable, moves are simultaneous, and we allow agents to communicate globally. For this setting, we give the first non-trivial lower bounds that bridge the gap between small ($k \leq \sqrt n$) and large ($k \geq n$) teams of agents. Remarkably, our bounds tightly connect to existing results in both domains. First, we significantly extend a lower bound of $\Omega(\log k / \log\log k)$ by Dynia et al. on the competitive ratio of a collaborative tree exploration strategy to the range $k \leq n \log^c n$ for any $c \in \mathbb{N}$. Second, we provide a tight lower bound on the number of agents needed for any competitive exploration algorithm. In particular, we show that any collaborative tree exploration algorithm with $k = Dn^{1+o(1)}$ agents has a competitive ratio of $\omega(1)$, while Dereniowski et al. gave an algorithm with $k = Dn^{1+\varepsilon}$ agents and competitive ratio $O(1)$, for any $\varepsilon > 0$ and with $D$ denoting the diameter of the graph. Lastly, we show that, for any exploration algorithm using $k = n$ agents, there exist trees of arbitrarily large height $D$ that require $\Omega(D^2)$ rounds, and we provide a simple algorithm that matches this bound for all trees

Parallel narratives: resistance strategies of low-wage female hospitality workers and nineteenth-century black enslaved females

This research explores control and gendered resistance strategies of female low-level hospitality workers and nineteenth-century black enslaved females by linking resistance patterns in historically documented slave narratives with oral narratives of current female hospitality workers. Emerging narratives document parallel stories of oppression, abuse, devaluation, and exploitation and focus awareness on the subordinate position of low-level workers in an oppressor/oppressed relationship. Functioning under two different economic systems, slavery and capitalism, these low-level workers’ narratives allow similar patterns of resistance to surface and help us expand our understanding of worker exploitation, female resistance, and narrative as possessing liberatory potential

Human Trafficking by the Numbers: The Initial Benchmark of Prevalence and Economic Impact for Texas

Prevalence HighlightsCurrently, there are approximately 79,000 minor and youth victims of sex trafficking in Texas.Currently, there are approximately 234,000 workers who are victims of labor trafficking in Texas.Currently, there arean estimated 313,000 victims of human trafficking in Texas.Cost HighlightsMinor and youth sex trafficking costs the state of Texas approximately $6.6 billion. Traffickers exploit approximately$600 million from victims of labor trafficking in Texas.BackgroundThough human trafficking is widespread in geographically large states with large urban centers like Texas, the true scope of this hidden crime is largely unconfirmed as data on human trafficking are difficult to ascertain. Existing data gathered in anti-trafficking efforts focus almost exclusively on identified victims, shedding light on only a fraction of the problem. The first phase of the Statewide Human Trafficking Mapping Project of Texas focused on providing empiricallygrounded data as a benchmark about the extent of human trafficking across the state. The following three primary research questions guided our data collection efforts, which included queries of existing databases, interviews, focus groups, and web-based surveys.1.What is the prevalence of human trafficking in Texas?2.What is the economic impact of human trafficking in Texas?3.What is our understanding of human trafficking in Texas?MethodsThe findings in this report were derived using a multi-methods approach to quantify the prevalence and economic impact of human trafficking in Texas. Higher-than-average risk industry and community segments were chosen for sex and labor markets. We defined community segments asgroups of people considered to be at higher-than-average risk of trafficking because of risk indicators found in trafficking cases (e.g. homelessness). More specifically, rather than attempting to establish prevalence of trafficking among the 27.4 million people living in Texas, for the purposes of demonstrating our methodology, establishing some benchmarks on human trafficking prevalence and economic impact estimates, and providing a concrete example of our planned activities moving forward, victimization rates were applied to a select few community segments that are at higher-than-average risk of trafficking.The methodology has addressed the critical industry and community segments to accurately estimate prevalencewhile reducing overlap between the chosen segments
