Dynamic characteristics and adaptability of mouse vestibulo-ocular and optokinetic response eye movements and the role of the flocculo-olivary system revealed by chemical lesions

The dynamic characteristics of reflex eye movements were measured in two strains of chronically prepared mice by using an infrared television camera system. The horizontal vestibulo-ocular reflex (HVOR) and horizontal optokinetic response (HOKR) were induced by sinusoidal oscillations of a turntable, in darkness, by 10° (peak to peak) at 0.11–0.50 Hz and of a checked-pattern screen, in light, by 5–20°at 0.11–0.17 Hz, respectively. The gains and phases of the HVOR and HOKR of the C57BL/6 mice were nearly equivalent to those of rabbits and rats, whereas the 129/Sv mice exhibited very low gains in the HVOR and moderate phase lags in the HOKR, suggesting an inherent sensory-motor anomaly. Adaptability of the HOKR was examined in C57BL/6 mice by sustained screen oscillation. When the screen was oscillated by 10° at 0.17 Hz, which induced sufficient retinal slips, the gain of the HOKR increased by 0.08 in 1 h on average, whereas the stimuli that induced relatively small or no retinal slips affected the gain very little. Lesions of the flocculi induced by local applications of 0.1% ibotenic acid and lesions of the inferior olivary nuclei induced by i.p. injection of 3-acetylpyridine in C57BL/6 mice little affected the dynamic characteristics of the HVOR and HOKR, but abolished the adaptation of the HOKR. These results indicate that the olivo-floccular system plays an essential role in the adaptive control of the ocular reflex in mice, as suggested in other animal species. The data presented provide the basis for analyzing the reflex eye movements of genetically engineered mice.

Efforts towards adaptability enhancement:how manufacturing and service industries can learn from each other

This paper discusses the recent emerging efforts for adaptability enhancement of Japanese industries to cope with a volatile demand environment. It is based on an analysis of data obtained from respondent companies. The analysis is focused on both manufacturing and manufacturing- related service industries such as construction/maintenance, software supply, manufacturing consultation and logistics industries to highlight their current situation, the sense of crisis in Japanese companies and possible future directions in relation to the two industry sectors. The principal conclusion is that for most companies consideration of a revision or modification to its cost structure is an essential requirement for survival in the global competitive environment.

Formalizált rugalmasság – a kettős képesség kialakulása egy középvállalatban (Formalized adaptability: the development of ambidexterity in a medium-sized enterprise)

Az empirikus kutatás azokra a kérdésekre keresi a választ, hogy a hazai innovatív, növekedésorientált kis- és középvállalkozásokat milyen tényezők támogatják és segítik abban, hogy egyszerre legyenek képesek kiválóan teljesíteni jelenlegi piacaikon, miközben radikális innovációikon keresztül biztosítják a szervezet hosszú távú növekedési pályáját. A kutatás kvalitatív, feltáró, egyéni interjúkra épülő esettanulmányos módszertan keretein belül 14 vezetői interjúra, helyszíni megfigyelésre és széles körű dokumentumelemzésre épül. Az eredmények alapján a kettős képességű szervezetek teljesítményét egy hat, egymással összefüggésben lévő elemből álló modell határozza meg, melynek részei a felsővezetői decentralizáció, menedzsmentkontroll, vezetői szerepek és identitás, feladat- és hatáskörök, motivációs rendszer és a menedzsmenttudás színvonala. _______ The empirical research seeks the answer to the question what kind of factors support and help the innovative, growth-oriented Hungarian SMEs to both have the ability to operate at an excellent level in their current markets and to ensure the long-term growth path of the organization through radical innovations. The research applies qualitative, interview-based methodology. The dataset consists of 14 interviews with managers from different organizational level of the examined company, on-site observation and document-analysis. The main contribution of the article is a model that includes the influential structural and contextual factors of organizational ambidexterity, which are decentralization, management controlling, leader roles and identity, functions and authorities, motivation system and level of management knowledge.

Adaptability of nonlinear equilibrum models to central planning

Linear multisectoral models have for long been applied in the Hungarian national economic planning. Price-quantity correspondences and interaction, however, cannot easily be taken into account in the traditional linear framework. Computable general equilibrium modelers in the West have developed techniques which use extensively price-quantity interdependences. However, since they are usually presented with the controversial strict neoclassical interpretation, the possibility of their adaptation to socialist planning models has been concaled. This paper reflects on some results of a research investigating the possible adaptation of eqailibrium modeling techniques to central planning models.

Enabling adaptability in service aggregates using transparent shaping techniques

Distributed applications are exposed as reusable components that are dynamically discovered and integrated to create new applications. These new applications, in the form of aggregate services, are vulnerable to failure due to the autonomous and distributed nature of their integrated components. This vulnerability creates the need for adaptability in aggregate services. The need for adaptation is accentuated for complex long-running applications as is found in scientific Grid computing, where distributed computing nodes may participate to solve computation and data-intensive problems. Such applications integrate services for coordinated problem solving in areas such as Bioinformatics. For such applications, when a constituent service fails, the application fails, even though there are other nodes that can substitute for the failed service. This concern is not addressed in the specification of high-level composition languages such as that of the Business Process Execution Language (BPEL). We propose an approach to transparently autonomizing existing BPEL processes in order to make them modifiable at runtime and more resilient to the failures in their execution environment. By transparent introduction of adaptive behavior, adaptation preserves the original business logic of the aggregate service and does not tangle the code for adaptive behavior with that of the aggregate service. The major contributions of this dissertation are: first, we assessed the effectiveness of BPEL language support in developing adaptive mechanisms. As a result, we identified the strengths and limitations of BPEL and came up with strategies to address those limitations. Second, we developed a technique to enhance existing BPEL processes transparently in order to support dynamic adaptation. We proposed a framework which uses transparent shaping and generative programming to make BPEL processes adaptive. Third, we developed a technique to dynamically discover and bind to substitute services. Our technique was evaluated and the result showed that dynamic utilization of components improves the flexibility of adaptive BPEL processes. Fourth, we developed an extensible policy-based technique to specify how to handle exceptional behavior. We developed a generic component that introduces adaptive behavior for multiple BPEL processes. Fifth, we identify ways to apply our work to facilitate adaptability in composite Grid services.
