LinkedIn as a new selection method: Psychometric properties and assessment approach

Various surveys suggest LinkedIn is used as a screening and selection tool by many hiring managers. Despite this widespread use, fairly little is known about whether LinkedIn meets established selection criteria, such as reliability, validity, and legality (i.e., no adverse impact). We examine the properties of LinkedIn-based assessments in two studies. Study 1 shows that raters reach acceptable levels of consistency in their assessments of applicant skills, personality, and cognitive ability. Initial ratings also correlate with subsequent ratings done 1-year later (i.e., demonstrating temporal stability), with slightly higher correlations when profile updates are taken into account. Initial LinkedIn-based ratings correlate with self-reports for more visible skills (leadership, communication, and planning) and personality traits (Extraversion), and for cognitive ability. LinkedIn-based hiring recommendations are positively associated with indicators of career success. Potential adverse impact is also limited. Profiles that are longer, include a picture, and have more connections are rated more positively. Some of those features are valid cues to applicants’ characteristics (e.g., applicants high on Conscientiousness have longer profiles). In Study 2, we show that an itemized LinkedIn assessment is more effective than a global assessment. Implications of these findings for selection and future research are discussed.     

Naturalness constraints on best systems accounts of laws

According to best systems accounts, laws of nature are generalizations in the best systematization of particular matters of fact. Metrics such as simplicity and strength determine which systematization is best, but these are notoriously language relative. For this reason, David Lewis proposed a constraint on languages of inquiry: all predicates must be natural. This constraint is sometimes interpreted as requiring us to know which natural properties are instantiated in our world prior to scientific theorizing. I argue that this interpretation is incorrect. I provide a better interpretation and show how it undercuts an influential epistemological objection to Lewis's best systems account of laws due to Bas van Fraassen.     

An open measurement problem of interest

This open problem urges a seach for a nice “union” of algbraic measurement models having two or more operations and probabilistic choice models. The difficulty lies in arriving at probabilistic formulations of linking properties, such as distribution properties, between the two operations. The goal is a formulation that leads to a representation theorem in terms of a random variable representation and that reduces to a known algebraic representation when there is no noise.     

On universals: an extensionalist alternative to Quine’s resemblance theory

The notion of similarity plays a central role in Quine’s theory of Universals and it is with the help of this notion that Quine intends to define the concept of kind which also plays a central role in the theory. But as Quine has admitted, his attempts to define kinds in terms of similarities were unsuccessful and it is mainly because of this shortcoming that Quine’s theory has been ignored by several philosophers (see, e.g., Armstrong, D. M. (1978a). Nominalism and realism: Universals and Scientific realism (Vol. I). Cambridge: Cambridge University Press). In the present paper, I propose an alternative framework that accounts for the phenomena that Quine intends to explain with his resemblance theory. The framework agrees with Quine’s austere ontology; in particular, it does not assume the existence of properties and of possible worlds. (I will mention below Quine’s reason for rejecting properties and possible worlds. For a theory of Universals that assumes possible worlds, see, e.g., Rodriguez-Pereyra, G. (2002). Resemblance nominalism: A solution to the problem of Universals. Oxford: Clarendon Press.) Moreover, the framework is extensionalist since the abstract entities it assumes are classes and these can be individuated extensionally, for classes are identical if their members are identical. Finally, I will refute some of the objections to Quine’s approach that have been raised by Armstrong and Oliver [(1996). The metaphysics of properties. Mind, 105, 1–80.] and I will argue that, contrary to what has been claimed by Oliver in a comment on Lewis [(1986). On the plurality of worlds. Oxford: Blackwell.], Quine is able to specify an important set of sparse properties. Editor’s Note: Nathan Stemmer died on 6 April 2007. Due to this, the proofreading was only done by the editors. All colleagues being acquainted with Nathan Stemmers work are deeply concerned about the loss.     

The psychometric properties of the Portuguese version of the Personality Inventory for DSM‐5

The DSM‐5 Section III proposes a hybrid dimensional‐categorical model of conceptualizing personality and its disorders that includes assessment of impairments in personality functioning (criterion A) and maladaptive personality traits (criterion B). The Personality Inventory for the DSM‐5 is a new dimensional tool, composed of 220 items organized into 25 facets that delineate five higher order domains of clinically relevant personality differences, and was developed to operationalize the DSM‐5 model of pathological personality traits. The current studies address the internal consistency (study 1), the test‐retest reliability (study 2) and the criterion validity (studies 3 and 4) of the Portuguese version of the PID‐5 in samples of native speaking psychology students. Results indicated good internal consistency reliabilities and good temporal stability reliabilities for the majority of the PID‐5 traits. The correlational pattern of the PID‐5 traits with two measures of personality was in accordance with theoretical expectations and showed its concurrent validity.     

Effects of movement distance,duration, velocity,and type on action prediction in 12-month-olds

The goal of the present study was to test the influence of the spatial and temporal dynamics of observed manual actions on infants’ action prediction. Twelve-month-old infants were presented with reach-and-transport actions performed by a human agent. Movement distance, duration, and – resulting from the two – movement velocity were systematically varied. Action prediction was measured via the latency of gaze arrival at target in relation to agent’s hand. The results showed a general effect of all parameters on the infants’ perception of goal-directed actions: Infants were more likely to predict the action goal the longer the movement distance was, the longer the movement duration was, and the slower the movement velocity was. In addition, they were more likely to predict the goal of a reaching than a transport action. The present findings extent previous findings by showing that infants are not only sensitive to differences in distances, durations, and velocities at early age but that these factors have a strong impact on the prediction of the goal of observed actions.     

Taking Pictures of Jesus: Producing the Material Presence of a Divine Other

A new form of visual representation of divine others is emerging: photography. I examine here a set of photos of deities related to an apparition claim. The goal I pursue is to analyze the self-constitutive features of these pictures – how they produce what they claim to be. I argue that the “presence' of the deities in the photos is achieved through “incarnation practices.' But these pictures are not just a factual representation of alleged mystical events. They constitute an update and a variation on the “Grand Christian Narrative' wherein the factual poses the moral problem of belief. In that sense, divine photography does not modify the epistemology of religious belief.     

Are children moral objectivists? Children's judgments about moral and response-dependent properties

Researchers working on children's moral understanding maintain that the child's capacity to distinguish morality from convention shows that children regard moral violations as objectively wrong (e.g. Nucci, L. (2001). Education in the moral domain. Cambridge: Cambridge University Press). However, one traditional way to cast the issue of objectivism is to focus not on conventionality, but on whether moral properties depend on our responses, as with properties like icky and fun. This paper argues that the moral/conventional task is inadequate for assessing whether children regard moral properties as response-dependent. Unfortunately, children's understanding of response-dependent properties has been neglected in recent research. Two experiments are reported showing that children are more likely to treat properties like fun and icky as response-dependent than moral properties like good and bad. Hence, this helps support the claim that children are moral objectivists.
