Network learning: Episodes of interorganizational learning towards a collective performance goal

Little is known about learning processes in horizontal networks. This study focuses on networks as learning entities, i.e. learning by multiple organizations as a group, and the mechanisms involved in developing and addressing a network-level performance goal. By using a narrative approach, we gather in-depth primary data from network members to examine: how do firms engage in network learning? and, how is network learning coordinated towards a performance goal in a horizontal inter-firm network? Our findings comprise two learning episodes: ‘learning how to compete’ and ‘learning how to perform’. These episodes help us to understand network learning processes; the relationship between network learning and organizational learning; and the regulatory role a hub firm provides towards a collective performance goal.     

Keeping an Uphill Edge

Abstract

Several behaviors in a ski shop were identified as being deficient using Austin's Performance Diagnostic Checklist (2000) and Daniels and Daniels' PIC/NIC Analysis (2004). During a 4-week baseline, 7 cleaning behaviors were monitored and 5 were subsequently targeted in an intervention package using an ABC design. The intervention included: a task clarification session, a posted behavioral checklist, graphic feedback of the group's performance for the previous week, and daily task-specific feedback. Immediately after the checklist was posted, the frequency of employee cleaning behaviors increased 52%. Cleaning behaviors increased an additional 12% after the implementation of daily task-specific feedback. Results suggest the interventions generalized to the 2 cleaning behaviors not mentioned in the task-clarification session.     

A study of DEA models without explicit inputs

In performance evaluations, data without explicit inputs (such as index data, pure output data) are widely used. To directly use such data, this paper presents a study on building DEA models without explicit inputs, so-called DEA-WEI models, which are applicable to the evaluation applications where inputs are not directly considered. We provide an axiom foundation of these kinds of models, and further discuss how to incorporate value judgments of decision makers into these DEA-WEI models. Several such models are derived. Finally, applications of the DEA-WEI models are presented.     

Perceived professional standards and roles of public relations in China: Through the lens of Chinese public relations practitioners

As the first quantitative examination of perceived public relations professional standards in China using an online survey, this study was designed based on the standards of professional standards inventory Cameron, Sallot, & Lariscy (1996) constructed and tested among practitioners in the U.S. The survey results suggest six dimensions of perceived standards of professional performance: (1) role and function in organizational strategic planning, (2) sufficiency in professional training and preparedness, (3) gender and racial equity, (4) situational constraints, (5) licensing and organizational support, and (6) participation in the organizational decision-making team. Four dimensions of public relations roles were also identified by the survey participants: (1) brand promotion facilitator, (2) public information specialist, (3) media relations counsel, and (4) conflict management expert. Primary practice area was found to affect how Chinese practitioners perceive the six clusters of professional standards and the four identified public relations roles. These findings provide insights for both practitioners and researchers on how Chinese public relations practitioners view public relations as a profession and how the profession currently holds its professional standards in China.

Appropriate use of bright light promotes a durable adaptation to night-shifts and accelerates readjustment during recovery after a period of night-shifts

Abstract

The present study examines the stability of bright light circadian readjustment during two consecutive dim light night-work periods and circadian synchronization during the recovery after a night-shift period. A sample of 10 subjects was divided into 2 groups (control group: 6 subjects; experimental group: 4 subjects). All subjects worked during 5 days, between 23:00 and 07:00 h and then went to sleep. Subjects received 2500-3000 lux between 02:00 and 05:00 h during 5 days for the control group and 3 days for the experimental group. During recovery after the night-shift periods, three cycles of bright light were administered at two different times: 12:00-15:00 h for two of six subjects from the control group and 10:00-13:00 h for all subjects (4) of the experimental group. By the fifth cycle of night-work the maximum of urinary aMT6s excretion that occurs at 05:00 h in the baseline condition was shifted to 12:00 h for the control and experimental groups (delay in hours: 7±1.6 (control); 7±1 (experimental)). This result suggests that three cycles of bright light are sufficient to induce a significant phase delay and that this delay remained stable when night-work proceeded under dim light. The phase delay of the circadian aMT6s excretion by exposure to bright light was accompanied by an improvement of the quality of day sleep and level of cognitive and psychomotor performances for control and experimental groups. No significant difference was observed in the two groups for daytime sleep and nocturnal performance. The two bright light periods used during the three days of recovery induced a complete synchronization in five of six subjects. One subject showed a partial synchronization probably because he remained at the laboratory under dim light during the day and had few family and social contacts.     

Estimation of mean using double sampling for stratification and multivariate auxiliary information

Several estimators for estimating the mean of a principal variable are proposed based on double sampling for stratification (DSS) and multivariate auxiliary information. The general properties of the proposed estimators are studied, search for optimum estimators is made and the proposed estimators are compared with the corresponding estimators based on unstratified double sampling (USDS).     

A case study of the impact of integrated project governances on PPP project performance

Under the new normal state, the PPP project will play a more and more important role in the social and economic development of China. To improve the performance of PPP project management, it is necessary to implement integrated project governances. Firstly, according to the index system of two kinds of PPP projects governances (Contract Governance and Relationship Governance) and PPP project management performance determined by theoretical analysis, the DDX project is selected as the analysis object. After identifying the case, this paper explains the basic information and preliminary work of the case. Then, the three contents of contract governance, relationship governance and project performance are analyzed comprehensively. Case studies show that all of these two governance modes have positive effects on project management performance. However, due to the lack of information in the case, the validity of the conclusion also needs to be verified again.

Psychophysical conditions and hormonal secretion in nurses on a rapidly rotating shift schedule and exposed to bright light during night work

The psychophysical conditions of 15 young female nurses, working in a rapidly-rotating shift system (2-2-2-2), modified according to some psychophysiological criteria, and exposed to short period (4 × 20 min) of bright light (2350 Lux) during their night duty, were studied in order to evaluate their adaptation to night work and to test a possible positive effect on it of bright light. Subjective evaluations of work load and psychophysical conditions, performance measures, hormonal excretion (cortisol, 6-sulphatoxymelatonin and catecholamines), oral temperature and activity-sleep logs were taken during the shiftwork cycle, comprising one morning, one afternoon and two consecutive nights under normal and bright light. The results showed that this rapidly-rotating shift system had little effect upon the normal circadian rhythms of the body. Moreover, the lengthening of the night shift to 10 h can be considered to be acceptable, provided that work load is reduced and there are sufficient rest pauses available. On the other hand, the reduction to 7 h of the length of the day shifts and delayed start of the morning shift to 07:00 h appeared to be convenient both in relation to the work load and sleep duration. Some positive effects of bright light upon psychophysical conditions and performance efficiency were noted, while hormonal excretion and body temperature did not show any effect of bright light; in particular, melatonin excretion was not suppressed appreciably by the bright light used.
