Every ship will face an extension run-in stage after equipment factory test. In the paper, adjustable pitch propeller of the two ships in different wear processes are selected for the experiment and the features of hydraulic oil are obtained. With FA (factor analysis), the features of the contamination can be represented by two feature factors, large size particles factor and small size particles factor. According to comparison of the contribution of the ships two factors, large size particles factor of the ship in extension run-in stage have much more influence on the hydraulic oils status than the other ship.

Objective: The purposes of this investigation were to determine whether the temporal onsets of swallow events segment into oral and pharyngeal phases, to test the interdependence of temporal onsets of swallow events, and to determine the influence of age on total swallow duration. Study Design and Setting: The onsets of swallowing and respiratory measures were studied in 76 healthy normal individuals. Results: Confirmatory factor analysis revealed a 2-factor solution but did not support the hypothesized 2-phase structure (ie, oral and pharyngeal). Two of the onsets, apnea onset and apnea offset, formed a single factor that explained 12.6% of the variation among the 11 onset times. The other 9 onsets formed a second factor that explained 66.4% of the variation. Age accounted for modest variation in total swallow duration. Conclusions: The two factors, oropharyngeal and respiratory, explained 79% of the variation among the 11 onset times. Significance: This finding speaks to the overlap between the initiation of oral and pharyngeal components of swallowing in adults and highlights the artificiality of separating the swallowing continuum into isolated phases.

Based on the responses of 118 male and 79 female college students, a factor analysis of the 40 sex-typed items from the Bem Sex-role Inventory and sex of respondent yielded four factors which were almost identical to those reported by Waters, Waters, and Pincus (1977). One of the factors essentially represented the gender of the respondent. A second factor representing an expressive, affective orientation was defined by feminine sex-typed items. The other two factors were primarily defined by masculine sex-typed items. One stressed independence, self-sufficiency, and individuality while the other stressed leadership, aggressiveness, and forcefulness. These latter factors were interpreted in terms of an “agentic” orientation (Bakan, 1966) and an “instrumental” orientation (Parsons & Bales, 1955).

Our study examined the psychometric properties and factor structure of an instrument to assess emotional climate during the COVID-19 pandemic using a sample of 601 Portuguese individuals. Two sub-samples were created, one to perform an exploratory factor analysis (EFA), composed of 300 participants, and the other to conduct a confirmatory factor analysis (CFA), composed of 301 individuals. Two factors were found: positive and negative emotional climate. In the EFA, both factors established a negative and significant correlation. However, the CFA presented a better fit with two independent factors. Reliability analysis indicated acceptable values for both dimensions. There was also evidence of discriminant, convergent, and criterion validity. More negative emotions were perceived regarding the social climate. Results were discussed in the frame of different positive and negative psychosocial variables related to positive and negative emotional climates, as well as positive emotional climate as a resource for collective resilience.

Different Dimensions

Two samples of students completed the short form of the Beck Depression Inventory under different conditions. One sample completed the items embedded within the full scale, while the other sample completed only the items in the short form. Identical methods of factor analysis produced different factor patterns for the two samples. For the embedded items, three interpretable factors were derived, and the first two factors resembled results of previous analyses of the long form. Analysis of the other sample produced three new factors, indicating that the short form may be measuring different dimensions than the long form.

Multiple Replication

Replications of two factor analyses of the Bern Sex-role Inventory published in the 1970s were conducted for two samples of college students ( Ns = 362 and 267). Four factors, which were almost identical to those of the previous analyses, were obtained in each sample. One of the factors essentially represented the sex of the respondent. A second factor, representing an expressive, affective orientation, contained loadings of about half of the feminine sex-typed items. The masculine sex-typed items split into two factors. One stressed dominance, aggressiveness, and leadership while the other stressed independence, individuality, and self-sufficiency. These latter factors were interpreted in relation to two masculine orientations suggested by Bakan in 1966 and Parsons and Bales in 1955.

For nearly two decades, the Australian national project Advancing Science and Engineering through Laboratory Learning (ASELL), has been using an evidence based approach to improve undergraduate experiments. This paper presents the ASELL Students Laboratory Experience (ASLE) survey, administered to 2691 students in five disciplines: biochemistry, biology, chemistry, physics, and pharmacology. The 14 item survey probes students’ perceptions of an experiment, practical or fieldwork. An exploratory factor analysis extracted two factors, ‘experiment-based motivators’ and ‘course-level resources’, and both factors correlate well with ‘overall’ learning experiences. Each survey item was also compared to the ‘overall’ learning experiences of the experiment, revealing the most critical elements of each experiment. The implications of this analysis, for practitioners is that the survey items in the ‘course-level resources’ taper off indicating that after an optimum value, further investment in these aspects do not necessarily influence student perceptions of their learning experiences. On the other hand, the survey items in the ‘experiment-based motivators’ behave differently in that they do not taper off indicating that further investment can influence experiences. How these factors relate to the overall experience suggest they correspond to the well-known two-factor theory of motivation.

Abstract Research on staff supporting individuals with intellectual and developmental disabilities (IDD) tends to focus on negative aspects of the work. This study expanded on previous research on the positive consequences that work in the IDD field has on staff using a brief version of the Staff Positive Contributions Questionnaire with 926 staff. Factor analysis suggested two factors: General positive contributions and Positive work motivation. Positive work motivation was associated with high levels of personal accomplishment, but shared limited variance with the other two burnout dimensions (emotional exhaustion, depersonalization). Findings lend support to the idea that we need to consider both positive and negative aspects of work life. This brief scale may be a useful index of how staff benefit from their work.

Q methodology was used to determine attitudes and opinions about e-books among a group of faculty, graduate students, and undergraduates at Miami University of Ohio. Oral interviews formed the basis for a collection of opinion statements concerning e-books versus print. These statements were then ranked by a second group of research participants. Factor analysis of these rankings found four distinct factors that reveal clusters of opinions on e-books: Book Lovers, Technophiles, Pragmatists, and Printers. Two of the four factors take a more ideological approach in their understanding of e-books: Book Lovers have an emotional attachment to the printed book as an object, while Technophiles feel just as strongly about technology. In contrast, the other two factors are more utilitarian: Printers might find e-books more palatable if usability were improved, while Pragmatists are comfortable with both print and e-book formats.

Based on the responses of 252 (126 male, 126 female) college undergraduates, a factor analysis of the 40 sex-typed items from the Bern Sex-role Inventory and sex of respondent yielded four factors. One of the factors essentially represented the biological sex of the respondent. A second factor, representing an expressive, affective orientation, contained loadings of 14 of the 20 feminine sex-typed items. The other two factors (dominant, aggressive and independent, self-sufficient) were defined primarily by masculine sex-typed items. Biological sex of the respondent did not load on any of the three latter factors. The obtained factor structure was very similar to that reported by Gaudreau (1975) for non-college respondents. Taken together, these two analyses (a) support the use of the Masculinity and Femininity scales as independent constructs and (b) suggest several items that could be deleted from both scales to increase both homogeneity and interpretability.

AbstractWith a focus on a specific employment group this research attempted to add to the knowledge on the content of the psychological contract. Structured interviews with 35 managers generated 651 responses relating to the content of their psychological contracts. Analysis of those responses resulted in the development of an initial two-component measure of the contract. One component (23 items) included the managers' expectations relating to the organisation's obligations. The other component (16 items) included the managers' obligations relating to the perceived organisation's expectations. Validation of the measure was based on a questionnaire completed by 124 managers. Participants considered all items to be important aspects of the contract. Participants also rated as high the obligation of each party to meet the expectations of the other. Factor analysis of the measure revealed two factors in each component which, in line with previous research, were termed relational obligations and transactional obligations. A robust methodology is proposed for continuing research into the content of the psychological work contract.
