Purpose This study aims to (1) examine the mediating effect of strategic orientation on the effect of environmental uncertainties on business performance, and (2) examine the mediating effect of innovations on the effect of environmental uncertainties on performance of the business in the aviation industry in Indonesia. Design/methodology/approach The research design was conducted through a survey, and the testing form was carried out using “Relationship Causal Studies” or a study to analyze the causality among environmental uncertainties, strategic orientation, innovations and performance of branches/stations of airlines in the Indonesian aviation industry. The sample was selected by determining the number of branches/stations of the Indonesian airlines to be selected into the sample, then more than one unit managers were selected as respondents representing their respective branches/stations. The number of the target sample in this study was 250 branches. Techniques used to address the hypotheses of the present study were Descriptive Analysis and Structural Model Analysis. The inferential statistical analysis focuses on the subject of the analysis and data interpretation to draw conclusions. Findings These research findings provide a contextual overview of the aviation industry in Indonesia that activities to make innovations in airline branches play a vital role in encouraging business performance. Moreover, the analysis shows that the more innovative a branch the better its business performance. This corroborates the finding (Spacapan and Bastic, 2007; Talke, 2007) that being highly innovative can ensure sustainable and long-term business performance. Research limitations/implications The findings of this research suggest that innovations mediate the effect of environmental uncertainties on business performance. These findings corroborate the results of previous studies that suitability between strategic orientation and innovations of a company in response to environmental uncertainties will affect performance of the company (Li and Gima, 2001; Manu, 1992). These findings also strengthen the view that companies with a higher level of innovations (innovative) have better business performance and competitive advantages (Kessler and Chakrabarty, 1996; Salavou et al., 2004; Spacapan and Bastic, 2007). Furthermore, based on findings, it can be interpreted that management that is able to overcome barriers to innovations, maximize innovation resources and achieve the target of innovations in the form of creation of better products/services will have better performance. The ability of the management to identify and overcome barriers to innovations and maximize the sources of innovation will generate products or services that can be accepted by the customers and eventually these products and services will be able to compete with better business performance (Blumentritt and Danis, 2006). Practical implications Findings of this research indicate the positive and significant mediating effect between environmental uncertainties on business performance, through the mediation of innovations, competitive conditions of the industrial environment which can encourage organizations to evolutionarily be more innovative in managing business to compete in the long term (Franke, 2007). This is also consistent with the theory of evolutionary economics (Nelson and Winter, 2000) that the old strategy may not suit the changes in the environment, and therefore companies should continue to seek new breakthroughs with persistent improvement and innovations. Social implications Dynamic and competitive conditions of the industrial environment require organizations to more intensively explore sources (capabilities) of innovations and accelerate generation of the innovations (Franke, 2007; Berry et al., 2006; Dobni, 2006; Davila et al., 2006; Spacapan and Bastic, 2007). Contextually, it appears that the competitive conditions of the aviation industry in either the short term or in the long term require business actors to be more innovative and to survive (Franke, 2007). Originality/value Innovations in business models as a new effort in improvisation specific to the business stage of the basic model (not very valuable) become more advanced business processes to produce products that are more valuable for consumers, at a more efficient cost with better profitability (Chesbrough, 2007b). So far, research on the role of innovations in response to environmental uncertainties and implementation of strategies to improve the performance of the environment-strategy-performance (ESP) model is still done partially so that there is no comprehensive model to describe the role of innovations in this ESP model, or let us say that a gap between theories and opportunities to do further research on the role of innovations in the ESP model exists.

AbstractNeurobiology-based interventions for mental diseases and searches for useful biomarkers of treatment response have largely failed. Clinical trials should assess interventions related to environmental and social stressors, with long-term follow-up; social rather than biological endpoints; personalized outcomes; and suitable cluster, adaptive, and n-of-1 designs. Labor, education, financial, and other social/political decisions should be evaluated for their impacts on mental disease.

AbstractRapid serial visual presentation (RSVP) of words or pictured scenes provides evidence for a large-capacity conceptual short-term memory (CSTM) that momentarily provides rich associated material from long-term memory, permitting rapid chunking (Potter 1993; 2009; 2012). In perception of scenes as well as language comprehension, we make use of knowledge that briefly exceeds the supposed limits of working memory.

AbstractA long-term photographic search programme for minor planets was begun at the Kleť Observatory at the end of seventies using a 0.63-m Maksutov telescope, but with insufficient respect for long-arc follow-up astrometry. More than two thousand provisional designations were given to new Kleť discoveries. Since 1993 targeted follow-up astrometry of Kleť candidates has been performed with a 0.57-m reflector equipped with a CCD camera, and reliable orbits for many previous Kleť discoveries have been determined. The photographic programme results in more than 350 numbered minor planets credited to Kleť, one of the world's most prolific discovery sites. Nearly 50 per cent of them were numbered as a consequence of CCD follow-up observations since 1994.This brief summary describes the results of this Kleť photographic minor planet survey between 1977 and 1996. The majority of the Kleť photographic discoveries are main belt asteroids, but two Amor type asteroids and one Trojan have been found.

AbstractThe large-scale coronal structures observed during the sporadically visible solar eclipses were compared with the numerically extrapolated field-line structures of coronal magnetic field. A characteristic relationship between the observed structures of coronal plasma and the magnetic field line configurations was determined. The long-term evolution of large scale coronal structures inferred from photospheric magnetic observations in the course of 11- and 22-year solar cycles is described.Some known parameters, such as the source surface radius, or coronal rotation rate are discussed and actually interpreted. A relation between the large-scale photospheric magnetic field evolution and the coronal structure rearrangement is demonstrated.

Cyclic Variations

AbstractLong-term cyclic variations in the distribution of prominences and intensities of green (530.3 nm) and red (637.4 nm) coronal emission lines over solar cycles 18–23 are presented. Polar prominence branches will reach the poles at different epochs in cycle 23: the north branch at the beginning in 2002 and the south branch a year later (2003), respectively. The local maxima of intensities in the green line show both poleward- and equatorward-migrating branches. The poleward branches will reach the poles around cycle maxima like prominences, while the equatorward branches show a duration of 18 years and will end in cycle minima (2007). The red corona shows mostly equatorward branches. The possibility that these branches begin to develop at high latitudes in the preceding cycles cannot be excluded.

The developing mammalian fetus is thought to be highly sensitive to ionizing radiation. However, dose, dose-rate relationships are not well established, especially the long term effects of protracted, low-dose exposure. A previous report (1) has indicated that bred beagle bitches exposed to daily doses of 5 to 35 R 60Co gamma rays throughout gestation can produce viable, seemingly normal offspring. Puppies irradiated in utero are distinguishable from controls only by their smaller size, dental abnormalities, and, in adulthood, by their inability to bear young.We report here our preliminary microscopic evaluation of ovarian pathology in young pups continuously irradiated throughout gestation at daily (22 h/day) dose rates of either 0.4, 1.0, 2.5, or 5.0 R/day of gamma rays from an attenuated 60Co source. Pups from non-irradiated bitches served as controls. Experimental animals were evaluated clinically and hematologically (control + 5.0 R/day pups) at regular intervals.
