Evolution of Growth Model and Cultivation of Competitive Advantages Under the Ambidextrous Innovation Strategy: In the Case of China’s High-Tech Enterprises

This study focuses on the evolution of growth model and cultivation of competitive advantages under the ambidextrous innovation strategy.After a brief introduction of the connotation of ambidextrous innovation strategy,the evolution of growth model of high-tech enterprises under the conventional strategy and the ambidextrous innovation strategy is analyzed.Furthermore,a discussion is made on how to cultivate enterprises’competitive advantages under the ambidextrous innovation strategy,thereby enabling enterprises to stand out from competitors under this new strategic model and truly achieve the goal of sustainable development.

Helical Repeats of Left-Handed DNA

DNA is generally assumed as a right-handed double helix and Z-DNA is a special kind of left-handed DNA infrequently found in nature. However, the finding of a zero linking number topoisomer supports a hypothesis that the two strands of DNA are winding ambidextrously, rather than plectonemically. It logically leads to a notion that the left-handed DNA is as common as right-handed DNA and the amount of left-handed DNA in a positively supercoiled plasmid prevails that of the right-handed DNA. In this report, the helical repeat of left-handed DNA, 12 bp per turn, was determined by a new method. How the positively supercoiled DNA was generated in hyperthermophiles and why their DNA can withstand the extreme high temperature are answered from an alternative theory.

The Evolution of Innovation Mode for Technology-Based Small and Medium-Sized Enterprises under the Synergy of Opportunity Identification and Ambidextrous Strategic Combination

Taking Company M as the research object,this studyadopts a case study methodtoexploretheevolutionofenterprise competitive advantage differentiation matching and resource-focused action in the iterative innovation process under the synergy of opportunity identification and ambidextrous strategic combination.This study reveals the formation mechanism and path of iterative innovation in enterprises,finding that opportunity identification is a dynamic and complex process with significant variations.Enterprises can creativeyly utilize the synergbyetween ambidextrous strategic combinations based on the identified opportunities to stimulate differentiated allocation of competitive advantage modules based on resource heterogeneity and incomplete factor-mobility,and to achieve strategic flexibility.The adaptive interaction between opportunity identification and ambidextrous strategic combination drives the staged evolution of resource-focused action,including resource bricolage,arrangement,and orchestration,thereby realizing the iterative innovation process of"technology exploration based development model-market expansion-based development model-collaborative innovation-based development model."

Impact of Organisational Distance on Technology Standard Alliance Performance:The Mediating Role of Ambidextrous learning

Technology standards are key elements for enterprises to dominate a market.The globalisation of innovation has intensified standard competition,making it generally difficult for a single enterprise to obtain all the resources needed to develop standards.Therefore,enterprises actively join technology standard alliances(TSAs)to seek collaborative innovation and develop technology standards to gain more competitive advantages.This study addresses a crucial issue for enterprises in TSAs and attempts to help them overcome the confines of organisational distance(OD)and improve technology standard alliance performance(TSAP).Through an empirical study of 325 Chinese information and manufacturing enterprises participating in TSAs,we find that OD negatively affects TSAP,and that exploratory learning(ERL)and exploitative learning(EIL)play mediating roles in the relationship between OD and TSAP.The innovation climate(IC)plays a moderating role in the relationship between OD and ERL,and OD and EIL.The results might deepen the understanding of OD in the context of TSAs and have implications for enterprise standardisation practices.

Optically Ambidextrous Reflection and Luminescence in Self-Organized Left-Handed Chiral Nematic Cellulose Nanocrystal Films

Defect-embedded chiral nematic organizations are attractive due to their light manipulation ability that is crucial for photonic applications.Self-assembly of cellulose nanocrystals(CNC)forms a left-handed chiral nematic structure,which makes simultaneous reflection of left-handed circularly polarized(LCP)and right-handed circularly polarized(RCP)light a challenging task.Herein,we present unprecedented evidence that self-organized CNC films with left-handed helical sense and photonic bandgaps(PBG)display ambidextrous CP light reflection with peak reflectivity up to 68%and transform spontaneous photoluminescence to RCP and LCP luminescence with respective|glum|values up to 0.796 and 0.120.These ambidextrous chiroptical properties originate from a left-handed chiral nematic structure consisting of a nematic-like phase,acting as a half-wave retarder,sandwiched between two PBG layers.The latter are spontaneously intercalated into the left-handed helicoids by rapid gelation of CNC colloidal suspensions.We demonstrate that the ambidextrous chiroptical properties can be manipulated by changes in evaporation temperatures,concentrations,and characteristics of CNC suspensions.We showcase the potential of defect-embedded chiral nematic CNC films for the sustainable and scalable development of anti-counterfeiting optical labels.
