Abstract This paper proposes an addition to Kondratyev’s theory of the emergence of innovations in long cycles. Regularities of the emergence of crisis phenomena and the concept of “avalanche-like growth of innovations” are considered. The study investigated the innovation peaks occurring in the middle of the depression phase, followed by the growth stages of economic activity after a certain period of time. Research has shown that the active emergence of innovations, which we have called the “snowballing growth of innovations,” falls in the middle of the depression phase. The authors investigated and supplemented the theory of the triggering effect of depression, which is similar to the action of the trigger, which results in an “avalanche-like growth of innovations”. To describe the processes associated with resonance and trigger effects, the authors propose to use the parametric resonance model and the Mathieu equation. With the help of mathematical modeling of innovation processes, a more accurate description of the periodic change in the number of innovations over time is possible, namely, the “avalanche-like growth of innovations”.

With the introduction of the new auxinic herbicide halauxifen-methyl into the oilseed rape (Brassica napus) market, there is a need to understand how this new molecule interacts with indigenous plant hormones (e.g., IAA) in terms of crop response. The aim of this study was to investigate the molecular background by using different growth conditions under which three different auxinic herbicides were administered. These were halauxifen-methyl (Hal), alone and together with aminopyralid (AP) as well as picloram (Pic). Three different hormone classes were determined, free and conjugated indole-3-acetic acid (IAA), aminocyclopropane carboxylic acid (ACC) as a precursor for ethylene, and abscisic acid (ABA) at two different temperatures and growth stages as well as over time (2–168 h after treatment). At 15 °C growth temperature, the effect was more pronounced than at 9 °C, and generally, the younger leaves independent of the developmental stage showed a larger effect on the alterations of hormones. IAA and ACC showed reproducible alterations after auxinic herbicide treatments over time, while ABA did not. Finally, a transcriptome analysis after treatment with two auxinic herbicides, Hal and Pic, showed different expression patterns. Hal treatment leads to the upregulation of auxin and hormone responses at 48 h and 96 h. Pic treatment induced the hormone/auxin response already after 2 h, and this continued for the other time points. The more detailed analysis of the auxin response in the datasets indicate a role for GH3 genes and genes encoding auxin efflux proteins. The upregulation of the GH3 genes correlates with the increase in conjugated IAA at the same time points and treatments. Also, genes for were found that confirm the upregulation of the ethylene pathway.

Intact ‘Seyval’ grape clusters in the greenhouse and ‘Catawba’ clusters in the field were inoculated with conidia of Phomopsis viticola at seven Eichorn-Lorenz growth stages between 12 (prebloom) and 35 (véraison) in 1998. Five pots (10 clusters) were used per inoculation, and the experiment was repeated three times. Also, 10 to 20 randomly selected Catawba clusters were inoculated in the field for each of three replications at each growth stage. Studies were repeated in 1999. In addition, Chambourcin clusters were also inoculated at four growth stages in the greenhouse in 1999. Results obtained in the greenhouse and field during both years and for all cultivars indicate that berry and rachis infections can occur at all growth stages between 12 and 35 with no evidence of decreasing susceptibility over time. Results disagree with some literature reports that indicate that berry infection occurs primarily during bloom and shortly after bloom, and susceptibility decreases as fruit matures.

Value co-creation is a specific type of collaboration that is considered to be an innovative and interactive process between end users and organizations; it aims to increase the value of a product or service. This study investigates how a network of stakeholders collaborating to manage innovation openly co-creates value over time; it contributes to the existing literature on value co-creation by taking the perspective of the network as a whole. The study follows a case in which value co-creation unfolds over time across a network of stakeholders within the business-to-business facility service context. The in-depth longitudinal investigation of a network composed of a corporate customer and its external facility service providers revealed that a network of stakeholders co-creates value over time by (i) offering an adaptable structure for the network to organize innovation activities and establish support routines, (ii) facilitating interactions to support stakeholder relation development and (iii) allowing participants to achieve self-empowerment. Therefore, stakeholder value co-creation entails the combination of single value co-creation activities and overarching network progressions that allow for learning and inter-organizational trust among stakeholders.

This paper aims to understand about how uncertainty emerges in the innovation process. Since uncertainty is embedded in the innovation process, to understand how uncertainty emerges in the process one needs to understand how innovation process unfolds over time. Since an innovation process involves various resource recombination activities occurring in several phases, to understand how innovation process unfolds one needs understand “how do various resource recombination activities occur over time for the creation of novelty?” This knowledge would enable us to understand the conditions under which vital activities of resource recombination can/cannot be undertaken and coordinated as well as would allow us to understand the underlying decisions made by the innovators for their efficient undertaking and coordination. This paper investigates the innovation process in two companies through performing qualitative study. The innovation processes are analysed in the light of a conceptual model developed based on the Dubois’ (1994) End-product related activity structure model, Håkansson’s (1987) “ARA model” and Goldratt’s (1997) “Critical chain concept”. The findings suggest that uncertainty emerges in the innovation process in a cycle of interaction with resource void, activity void and actors’ limited cognition due to lack of knowledge, undue optimism, and rationally justified reason for disregarding information. Accordingly, a great deal of compromises is made while undertaking the activities.

Accounting means normally a basis while making management decisions; it is the information tool in order to highlight the strategies and to confirm their success. There are also cases where the roles are reversed and the management delineates the accounting directions according to the results obtained, thus being transformed from the company management for results to the results themselves. Even if over time, the information and activity monitoring techniques improved, the precision of the economic and financial data remains dependent on the reporting referential and the manipulation technique of the results. The article is meant to highlight the items capable to characterise the choice of a management based on results, the conditions of its development, how the financial and accounting information users are affected, particularly the investors, as well as how it can be detected. It is also highlighted the fact that the management based on results plays a very important role for the apparition and development of the accounting engineering at the level of company by the determination it exercises over the managers while achieving or surpassing the objectives. Thus, there is the issue of a false reflection of the company’s activity, regarded by the prism of the management objectives, making particularly sensitive the passage from the economic reality of the company to the management ideals of the management. The financial and accounting information remains as main source of reflection of the economic activity and of the results of these activities, both for the own managers of the entities and for the large diversity of third parties: providers, customers, employees, investors, banks, State institutions etc., that makes it vulnerable in front of the external actions. It is important that in any management plan, its accounting represents a source of information for the management and not a means of obtaining the results.

Analytical studies of theoretical and methodological aspects of company’s strategic positioning influenced by unpredictable factors of changeable environment are examined in the article. Justification of effective choice of strategic position is provided by the concept of formation of company’s economic activity context in emergent environment proposed by the authors. Problems of strengthening of company’s strategic position in conditions of changeable economic environment with undefined factors can be solved by means of the developed model of company’s economic activity context on the basis of methods of mathematical modeling. One of the advantages of the model implementation can be the usage of methodology of company’s strategic positioning in economic environment. The model elaborated by the authors implies a set of analytical-calculative aspects of testing and further implementation in strategic management practice. The given article proposes the first conceptual methodological stage of model of company’s economic activity context implementation. The obtained results of further adoption can be applied as element of strategic management of vertically integrated companies in conditions of emergent environmental challenges.

Abstract Using a representative longitudinal survey of U.S. households, we find that household income became noticeably more volatile between the early 1970s and the late 2000s despite the moderation seen in aggregate economic activity during this period. We estimate that the standard deviation of percent changes in household income rose about 30 percent between 1971 and 2008. This widening in the distribution of percent changes was concentrated in the tails. The share of households experiencing a 50 percent plunge in income over a two-year period climbed from about 7 percent in the early 1970s to more than 12 percent in the early 2000s before retreating to 10 percent in the run-up to the Great Recession. Households’ labor earnings and transfer payments have both become more volatile over time. As best we can tell, the rise in the volatility of men’s earnings appears to owe both to greater volatility in earnings per hour and in hours worked.

Governments are important players in many parts of the economy, and at present perhaps the most visible is the balance they set between taxing and spending. Tax and spending polices are in part designed to redistribute resources between individuals, but they can also be used to redistribute resources over time. Governments can also use tax and spending policies to sustain or restrain economic activity, and in most countries a case can be made for using active fiscal policy in periods of clear economic distress, or in periods when it would be useful to restrain imbalances that can lead to financial crises. As a result it is difficult to gauge the appropriate stance of policy. Short-run problems have to be balanced against longer-term needs, and mistakes are common. In the UK, for instance, in the six years up until 2008 the balance of policy was perhaps too loose, whilst over the next five years it is probably too tight, even though deficits are projected to be higher than they were before 2009.
