Some Problems Concerning the Assessment of Job Characteristics in Nursing Work

Abstract

The question of whether one should use subjective rather than “objective” assessments of job characteristics is still the subject of a vigorous discussion in analytical studies of jobs and in job design. In nursing work situations, too, the attention of managers and researchers for such studies is growing. In this article the results of a study are presented in which a comparison is made between two kinds of assessments: job characteristics as judged by task performers (nurses) and job characteristics as judged by non-task performers (nursing management). Differences and agreements between mean scores as well as between correlations with dependent variables like job satisfaction were analysed. Most agreement seems to be on the ratings of “complexity and difficulty”, “work pressure”, and “promotion and growth opportunities”. As to “feedback and clarity”, “autonomy”, and “patient caring opportunities”, differences between the ratings have been found. It appears that a larger number of correlations between the nurse-rated job characteristics and the reaction variables is found to be statistically significant than between the management-rated job characteristics and the reaction variables. Social, organizational, and methodological reasons for the observed differences are put forward.     

The effect of methylphenidate on three forms of response inhibition in boys with AD/HD

The current study was aimed at (a) investigating the effect of three doses methylphenidate (MPH) and placebo on inhibition of a prepotent response, inhibition of an ongoing response, and interference control in Attention Deficit/Hyperactivity Disorder (AD/HD), and (b) studying dose-response relations for the three forms of response inhibition. To meet these aims, the following tasks were selected: two versions of the Stop Paradigm for inhibition of a prepotent response, a Circle Tracing Task and a recently developed Follow Task for inhibition of an ongoing response, and the Stroop Color-Word Test and an Eriksen Flanker Task for interference control. These tasks were administered to 23 boys with AD/HD during four treatment conditions: 5 mg MPH, 10 mg MPH, 20 mg MPH, and placebo. A pseudorandomized, multiple-blind, placebo-controlled, within-subject design was used. As hypothesized, inhibitory control in children with AD/HD improved under MPH compared to placebo. However, this effect was only significant for inhibition of a prepotent response and inhibition of an ongoing response (as measured by the Follow Task), but not for interference control. The relation between treatment condition and response was linear. However, this linear relation was due to improved inhibitory control under MPH compared to placebo, because no effects of MPH dose were observed for any of the response inhibition measures.     

Action unit classification using active appearance models and conditional random fields

In this paper, we investigate to what extent modern computer vision and machine learning techniques can assist social psychology research by automatically recognizing facial expressions. To this end, we develop a system that automatically recognizes the action units defined in the facial action coding system (FACS). The system uses a sophisticated deformable template, which is known as the active appearance model, to model the appearance of faces. The model is used to identify the location of facial feature points, as well as to extract features from the face that are indicative of the action unit states. The detection of the presence of action units is performed by a time series classification model, the linear-chain conditional random field. We evaluate the performance of our system in experiments on a large data set of videos with posed and natural facial expressions. In the experiments, we compare the action units detected by our approach with annotations made by human FACS annotators. Our results show that the agreement between the system and human FACS annotators is higher than 90% and underlines the potential of modern computer vision and machine learning techniques to social psychology research. We conclude with some suggestions on how systems like ours can play an important role in research on social signals.     

Reactions of Participants and Observers to Modes of Adjudication1

An important aspect of conflict resolution by judgment of a third party is the extent to which participants and observers are satisfied that both the procedure and the outcome are fair and impartial. Male undergraduates participated in a business simulation, which resulted in a controversy placing them in the position of defendants in a trial. An examination was then made of the effects of adversary and nonadversary procedures, prior belief about guilt, and favorableness of the judgment on participant subjects’perceptions of the adjudication. Another group of subjects who had no prior information about the guilt or innocence of the defendent served as observers. Participant subjects viewed the adversary procedure as most fair and satisfying. They were also most satisfied with judgments resulting from the adversary procedure, independently of pretrial belief or favorableness of verdict. Participants also preferred innocent to guilty verdicts, regardless of their pretrial belief. Subjects who held a pretrial belief of innocence were particularly dissatisfied with guilty verdicts and with the nonadversary trial procedure. Observers also found the adversary procedure to be most fair, and expressed a preference for innocent verdicts.     

Distributing Responsibility in the Debate on Sustainable Biofuels

In the perception of technology innovation two world views compete for domination: technological and social determinism. Technological determinism holds that societal change is caused by technological developments, social determinism holds the opposite. Although both were quite central to discussion in the philosophy, history and sociology of technology in the 1970s and 1980s, neither is seen as mainstream now. They do still play an important role as background philosophies in societal debates and offer two very different perspectives on where the responsibilities for an ethically sound development of novel technologies lie. In this paper we will elaborate on these to two opposing views on technology development taking the recent debate on the implementation of biofuels as a case example.     

Brain potentials implicate temporal lobe abnormalities in criminal psychopaths

Psychopathy is associated with abnormalities in attention and orienting. However, few studies have examined the neural systems underlying these processes. To address this issue, the authors recorded event-related potentials (ERPs) while 80 incarcerated men, classified as psychopathic or nonpsychopathic via the Hare Psychopathy Checklist--Revised (R. D. Hare, 1991, 2003), completed an auditory oddball task. Consistent with hypotheses, processing of targets elicited larger frontocentral negativities (N550) in psychopaths than in nonpsychopaths. Psychopaths also showed an enlarged N2 and reduced P3 during target detection. Similar ERP modulations have been reported in patients with amygdala and temporal lobe damage. The data are interpreted as supporting the hypothesis that psychopathy may be related to dysfunction of the paralimbic system--a system that includes parts of the temporal and frontal lobes.     

Mapping Response Repertoires

In his triangular model, Moscovici (1970, 1984) maintained that subjects do not have direct relations with the Object; rather, they have repertoires consisting of others’ responses, and these responses mediate the subject's relation with the Object. The present study examines response repertoires. We asked 114 participants to cite significant others and describe these others’ opinions about electromagnetic radiation, to indicate their own response on this issue, and to situate this response vis-à-vis the responses of the significant others described. Our results show that, even if some participants had restricted repertoires consisting of similar and rare responses, more than three-quarters of the participants had extended repertoires consisting of varied, shared, and consistent responses.     

The Dialogical Subject and its Multiple and Opposing Positions

The aim of our study is to describe how the voices of others constitute the dialogical subject: an individual who is not closed off from others, but is, rather, characterized by intersubjectivity and a plurality of positions in connection with those of others. Analysis of ten semi-structured interviews carried out on members of an association supporting the right of fathers to joint custody of children shows that interviewees employed a wide variety of voices – voices in support of shared custody, but also voices which opposed it. While they most often identified with and assumed voices in favor of joint custody, they also did so with voices expressing opposing positions. Our results belie the common expectation that individuals who are committed to a cause will not be open to the opinions of others, and are incapable of seeing the world from others’ points of view.     

A Comparison of Work Motivation in Bulgaria, Hungary, and the Netherlands: Test of a Model

This article describes a study into the antecedents and consequences of job involvement and organisational commitment of workers in Bulgaria, Hungary, and the Netherlands. On the basis of the literature a general model of work motivation is developed which depicts job characteristics, opportunities to satisfy needs, and extrinsic work factors as determinants of job involvement and organisational commitment, and considers effort expenditure, performance, job satisfaction, turnover, and work stress as outcomes. Data from worker samples in the three countries obtained with equivalent instruments are used to test the validity of the model. Path analysis shows that the model has a modest fit when applied to the three samples simultaneously. A better fit and more meaningful results are obtained by developing optimal models for each country. The peculiarities of these models can be largely explained from cultural and economic factors. Since the differences between Bulgaria and Hungary are as great as the differences with the Netherlands, there seems to be little evidence for a motivational after-effect of communism.
