Second-class citizen? Contract workers' perceived status,dual commitment and intent to quit

Outsourcing of jobs to contract workers who work alongside a client's employees has changed the human resource landscape of many organizations. In this study we examine how a contract worker's perceived employment status similarity to the client's own standard employees influences his/her affective commitment to both the client and the employer and ultimately intent to quit the employer. Using a sample of 623 contract workers, we found strong support for our hypotheses. In particular, findings indicate an important role for perceived employment status at the client organization in driving contract worker's attitudes and that contract workers consider both the client and the employer when making decisions to leave the employer. Implications for managing contractor relationships are discussed.     

Safety behavior can hamper the extinction of fear of movement-related pain: An experimental investigation in healthy participants

Excessive fear of movement-related pain (FMRP), and its associated avoidance behavior, is considered a major risk factor for disability in chronic musculoskeletal pain. The current study aimed to investigate whether engaging in safety behavior, conceptualized as an avoidance response, hampers the extinction of FMRP. In a differential conditioning paradigm, we used joystick movements as conditioned stimuli (CSs) and a painful electrocutaneous stimulus as the unconditioned stimulus (US). In the Safety group, participants received the opportunity to avoid the pain-US by pressing a safety button during the extinction phase, whereas in the Control group, this option was not included. In a subsequent test phase, this safety button was no longer available. In two experiments, results demonstrate successful acquisition and extinction. Retrospective FMRP ratings in both experiments revealed a return of fear of pain in the test phase in the Safety group, but not in the Control group. In Experiment 1, mean eyeblink startle reflex amplitudes partly corroborated the self-report findings on fear of pain. The present results suggest that performing safety behavior during cognitive-behavioral interventions, i.e., exposure, might increase the risk of a return of FMRP.     

Investigating the effect of intolerance of uncertainty on catastrophic worrying and mood

Intolerance of uncertainty (IU) is a construct known to influence catastrophic worry and is often observed in Generalized Anxiety Disorder (GAD). Research into the psychological manifestations of GAD suggests IU is associated with worry, but has not confirmed a causal link. The current study investigated the relationship between catastrophic worry and IU in a non-clinical undergraduate and postgraduate population (n = 46), with a mean age of 26.8 (SD = 5.52 years), where 71.74% were women. Participants received either a high or low IU manipulation, mood was measured throughout the study on 100 point visual analogue scales (VAS), and worry was measured using the catastrophising interview (CI). The high IU group generated significantly more catastrophising steps than the low IU group. Increased levels of sadness and anxiety were observed in the high as compared to the low IU group post IU manipulation, and this difference was maintained throughout the CI interview. A mediation analysis revealed that sadness and anxiety did not significantly mediate the relationship between IU and number of CI steps. These findings have implications for GAD treatment, as they suggest that manipulating IU affects measures of worry and its associated emotional and behavioural symptoms.     

Non‐standard work schedules and retention in the entry‐level hourly workforce

Non‐standard work schedules involve work outside the Monday–Friday daytime hours. Although research has heavily studied the health and family effects of such schedules, few studies have investigated their relationship to retention. We draw from Maertz and Campion's discussion of motivational forces that influence turnover to propose that employees on non‐standard schedules are more likely to quit their employer because of general job dissatisfaction and because of normative pressures from family and/or friends. Specifically, we hypothesized that employees on day shifts or weekday only schedules would remain with their employer longer than those who work on nonday shifts or on the weekends. We also hypothesized that perceived employment mobility would moderate the effects of non‐standard schedules on retention length. Hypotheses were tested among 3,178 retail employees who worked five different distinct shift arrangements and different weekday/weekend schedules. Cox regression analyses indicated that, as hypothesized, employees working nonday shifts or schedules including weekends remained with their employer for a shorter duration of time than employees not on such schedules. Perceived mobility moderated the schedule–turnover relationship, though not in the hypothesized manner. We discuss the theoretical and practical implications of these findings for work schedule assignment and retention strategies.     

Birth order of past presidents and Schlesinger's history cycles: support for Stewart's leadership theory

Stewart's hypothesis (1992) that adults who were only-children and first-born children are most suited to lead communities in more turbulent times while adults who were later-born children are most suited to lead in more tranquil times was tested by relating the male birth order of elected presidents to Schlesinger's 1986 public purpose and private interest periods. Consistent with Stewart's hypothesis, candidates who were only-children and first-born children tended to win during public purpose phases, which are characterized by the turbulence of greater political commitment, idealism, and broad social change.     

Comment on delayed left-ear accuracy in dichotic listening

Moulden and Persinger recently reported on the emergence of left-ear accuracy during childhood and adolescence. This commentary briefly discusses their findings with reference to previous studies that have reported on dichotic listening paradigms and, in particular, those in which a left-ear focus was used as a behavioral probe sensitive to developmental sex differences.     

The integration of orientation information in the motion correspondence problem

We examine how differently oriented components contribute to the discrimination of motion direction along a horizontal axis. Stimuli were two-frame random-dot kinematograms that were narrowband filtered in spatial frequency. On each trial, subjects had to state whether motion was to the left or the right. For each stimulus condition, Dmax (the largest displacement supporting 80% correct direction discrimination performance) was measured. In experiment 1, Dmax was measured for orientationally narrowband stimuli as a function of their mean orientation. Dmax was found to increase as the orientation of the stimuli became closer to the axis of motion. Experiment 2 used isotropic stimuli in which some orientation bands contained a coherent motion signal, and some contained only noise. When the noise band started at vertical orientations and increased until only horizontal orientations contained a coherent motion signal, Dmax increased slightly. This suggests that near-vertical orientations interfere with motion perception at large displacements when they contain a coherent motion signal. When the noise band started at horizontal and increased until only vertical orientations contained the motion signal, Dmax decreased steadily. This implies that Dmax depends at least partly on the most horizontal motion signal in the stimulus. These results were contrasted with two models. In the first, the visual system utilises the most informative orientations (nearest horizontal). In the second, all available orientations are used equally. Results supported an intermediate interpretation, in which all orientations are used but more informative ones are weighted more heavily.     

The acquisition of complex predicates in japanese specifically language-impaired and normally developing children

Japanese exhibits two different types of morphological processes. Some morphologically complex predicates are generated within the domain of the lexicon, whereas others are generated outside the domain of the lexicon. An elicited production task involving both types of complex predicates was administered to six Japanese children with specific language impairment (JSLI) and six children with normal language development (JNLD). The JSLI children experienced significant difficulty forming the lexicon-external complex predicates but much less difficulty with the lexicon-internal complex predicates while the performance of the JNLD children exhibited no such asymmetry. These preliminary results suggest that the deficit of SLI affects the ability to construct implicit procedural rules for morphology that are generated outside the lexicon while their lexical operations for morphology that are generated within the domain of the lexicon remain relatively unimpaired.
