Linking technological and educational level diversities to innovation performance

In this study, we explore the extent to which diversity of educational levels among research scientists and engineers (RSEs) in the context of a firm’s level of technological diversity influences innovation performance. We used data from the 2004–2008 National R&D Survey in Singapore. The results from 366 firms across different industries indicate that when a firm’s technological domains are heterogeneous, those firms with an RSE workforce comprising similar educational levels have positive innovation performance, measured as the number of patent applications, while those comprising diverse educational levels have negative innovation performance. Our further exploration of the positive interaction between technological domain heterogeneity and similarity of educational levels suggests that firms that had a high ratio of RSEs with lower educational levels had more positive patent outcomes compared to those that had a high ratio of RSEs with higher educational levels. The results show that there are limits to the strength of technological diversity in a firm’s absorptive capacity as explained by organizational demography.     

Report: increases in police use of force in the presence of body-worn cameras are driven by officer discretion: a protocol-based subgroup analysis of ten randomized experiments

Objectives

Our multisite randomized controlled trial reported that police body-worn cameras (BWCs) had, on average, no effect on recorded incidents of police use of force. In some sites, rates of use of force decreased and in others increased. We wanted to understand these counter-intuitive findings and report pre-specified subgroup analyses related to officers’ discretion on activating the BWCs.

Methods

Using pre-established criteria for experimental protocol breakdown in terms of treatment integrity, ten experimental sites were subgrouped into “high-compliance” (no officer discretion applied to when and where BWCs should be used; n?=?3), “no-compliance” (treatment integrity failure in both treatment and control conditions; n?=?4), and tests where officers applied discretion during treatment group but followed protocol in control conditions only (n?=?4).

Results

When officers complied with the experimental protocol and did not use discretion, use of force rates were 37 % lower [SMD?=?(?.346); SE?= .137; 95?% CI (?.614) – (?.077)]; when officers did not comply with treatment protocol (i.e., officers chose when to turn cameras on/off), use of force rates were 71 % higher [SMD?= .392; SE?= .130; 95?% CI (.136) – (.647)], compared to control conditions. When full discretion (i.e., overall breakdown of protocol) was applied to both treatment and control conditions, null effects were registered [SMD?= .009; SE=.070; 95?% CI (?.127) – (.146)], compared to control conditions.

Conclusions

BWCs can reduce police use of force when then officers’ discretion to turn cameras on or off is minimized—in terms of both case types as well as individual incidents. BWCs ought to be switched on and the recording announced to suspects at early stages of police–public interactions. Future BWCs tests should pay close attention to adherence to experimental protocols.

     

North Korea’s foreign relations: Diplomacy of promotive adaptation

Dramatic changes in East Europe and the Soviet Union resulted in North Korea’s doubling its effort to shield and defend itself from disturbances emanating from the outside. Yet, President Kim Il Sung of North Korea has also opted for new diplomatic moves of realignment in existing ties with China and the Soviet Union and is also seeking new rleations with Japan and the United States. North Korea’s diplomatic adaptation in 1990–91, such as its balancing diplomatic acts vis-à-vis the major allies and adversaries, is examined, and so is the North Korean dilemma of reconciling national interests and ideology. While Pyongyang’s nonaligned nations diplomacy is temporarily stalled, its Un diplomacy is likely to be activated as a result of the simultaneous entry into the United Nations with South Korea in 1991.
