Ideological parsimony

The theoretical virtue of parsimony values the minimizing of theoretical commitments, but theoretical commitments come in two kinds: ontological and ideological. While the ontological commitments of a theory are the entities it posits, a theory’s ideological commitments are the primitive concepts it employs. Here, I show how we can extend the distinction between quantitative and qualitative parsimony, commonly drawn regarding ontological commitments, to the domain of ideological commitments. I then argue that qualitative ideological parsimony is a theoretical virtue. My defense proceeds by demonstrating the merits of qualitative ideological parsimony and by showing how the qualitative conception of ideological parsimony undermines two notable arguments from ideological parsimony: David Lewis’ defense of modal realism and Ted Sider’s defense of mereological nihilism.     

Instantiation as location

Many familiar forms of property realism identify properties with sui generis ontological categories like universals or tropes and posit a fundamental instantiation relation that unifies objects with their properties. In this paper, I develop and defend locationism, which identifies properties with locations and holds that the occupation relation that unifies objects with their locations also unifies objects with their properties. Along with the theoretical parsimony that locationism enjoys, I argue that locationism resolves a puzzle for actualists regarding the ontological status of uninstantiated properties. I also note some promising applications of the locationist framework to the metaphysics of quantities and possible worlds.     

Measuring the effect of conflict on software engineering teams

This article describes a project that aimed to uncover the effects of different forms of conflict on team performance during the important feasibility, requirements analysis, and design phases of software engineering (SE) projects. The research subjects were master of science students who were working to produce software commissioned by real-world clients. A template was developed that allowed researchers to record details of any conflicts that occurred. It was found that some forms of conflict were more damaging than others and that the frequency and intensity of specific conflicts are important factors to consider. The experience of the researchers when using the final template suggests that it is a valuable weapon to have in one's arsenal if one is interested in observing and recording the details of conflict in either SE teams or teams in different contexts.     

Recombining non-qualitative reality

Haecceitism and Hume’s Dictum are each controversial theses about necessity and possibility. According to haecceitism, there are qualitatively indiscernible possible worlds that differ only with respect to which individuals occupy which qualitative roles. According to Hume’s Dictum, there are no necessary connections between distinct entities or, as Humeans sometimes put it, reality admits of “free recombination” so any entities can co-exist or fail to co-exist. This paper introduces a puzzle that results from the combination of haecceitism and Hume’s Dictum. This puzzle revolves around the free recombination of non-qualitative properties like being Socrates. After considering several responses to this puzzle, I defend an ideology-driven solution, which dispenses with non-qualitative properties like being Socrates in favour of primitive theoretical ideology while, at the same time, preserving a commitment to both haecceitism and Hume’s Dictum.

     

Changes in resident mix in nursing homes: cognitive and sensory data from a (redesigned) sampling plan

In planning and implementing a study, we unintentionally and serendipitously obtained data about changes in resident mix over a 2.8-yr. period. We screened residents of a 184-bed nursing home for cognition and sensorium in October 1984 to assess sampling feasibility for a grant proposal in preparation. At that time, 65.2% of the residents met the sampling criteria. However, in July/August 1987, after award of funding, only 5.4% of residents of the same nursing home met the cognitive and sensory criteria. We were forced to recruit from an additional six nursing homes, in which only 9.3% of residents met the sampling criteria.     

Using ethnographic methods to carry out human factors research in software engineering

This article describes how ethnographic methods were used to observe and analyze student teams working on software engineering (SE) projects. The aim of this research was to uncover the effects of the interplay of different personality types, as measured by a test based on the Myers-Briggs Type Indicator (MBTI), on the workings of an SE team. Using ethnographic methods allowed the researchers to record the effects of personality type on behavior toward teammates and how this related to the amount of disruption and positive ideas brought forward from each member; also examined in detail were issues that were either dogged by disruption or that did not have sufficient discussion devoted to them and the impact that they had on the outcomes of the project. Initial findings indicate that ethnographic methods are a valuable weapon to have in one’s arsenal when carrying out research into human factors of SE.

The Role of Christianity and Islam in Explaining Prejudice against Asylum Seekers: Evidence from Malaysia

ABSTRACT

Prejudicial attitudes toward asylum seekers are prevalent, and an emerging body of literature has revealed that this is partly driven by religious affiliation. The population of Malaysia is multireligious, making it a fruitful location for testing religion-based prejudice hypotheses. Thus, across 2 studies we tested the roles of Christianity and Islam in explicit and implicit prejudices against asylum seekers in the Malaysian context. In Study 1 (n = 97), we present evidence that there are religion-based differences in prejudice against asylum seekers; specifically, Muslims reported higher levels of (classical) explicit prejudice toward asylum seekers than Christians (there were no differences in conditional or implicit prejudices). In Study 2 (n = 117), we tested the hypothesis that these religion-based differences are qualified by the religion of the asylum seeker. In this study, we used a framing paradigm to experimentally manipulate the religion of the asylum-seeking targets. The results revealed an out-group exacerbation effect; that is, participants reported higher levels of prejudice toward asylum seekers who had a different religion from their own. For classical explicit prejudice, the effect was strongest from Muslims toward Christian asylum seekers. Conversely, for implicit prejudice, the reverse was true: The effect was strongest from Christians toward Muslim asylum seekers. These findings are discussed in terms of the political and social circumstances in Malaysia, but we interpret these findings as evidence that explicit and implicit attitudes toward asylum seekers are driven by a complex pattern of religion-based intergroup biases.
