A meta-analysis of consumer innovation resistance: is there a cultural invariance?

PurposeIn the literature of industrial management, the focus is normally given on examining the factors that contribute to product innovation acceptance. The advocates of “pro-innovation bias” assume that consumers are open to new products and are willing to accept an innovative product. However, there is a high failure rate of technological innovations and most of the technological innovations were rejected due to users' resistance. Since the inception of innovation resistance theory (IRT), the number of studies that used IRT has gained much attention from scholars. However, the findings from these studies from various contexts are inconsistent, lack universality, and a clear understanding of technological innovation barriers. The study aims to determine whether the IRT theory is indeed valid and whether IRT is culturally invariant from the Eastern and Western cultures.Design/methodology/approachA meta-analysis based on a random-effects model and studies drawn from 24 countries and/or regions with a consolidated sample size of 10,463 was conducted. Cultural invariance was identified based on subgroup analysis. Moderator analysis was performed by applying the weighted linear regression.FindingsThe results reveal that tradition is the strongest barrier followed by the value, risk, image and usage barrier. Interestingly, there is a cultural invariance in IRT from the Eastern and Western cultures. Besides, there are significant moderating effects due to the temporal factor.Originality/valueThe study has contributed useful theoretical and managerial implications in advancing the product innovation literature.

The peculiarities of assessing the psychophysiological traits of military pilots when exercising periodic control of their professionally important qualities

Annotation. The paper presents the results of statistical calculations of psychophysiological examinations of 80 military pilots and flight navigators with different levels of suitability for flight performance. The authors analyze the effects of the temporal factor (after the vacation leave) on the psychophysiological qualities of military pilots, other indices of individual typological and psychodynamic qualities which prove to be the indicator of the possibilities of man’s adaptation to the conditions of the task performance. With respect to investigating the above possibilities, we have determined the time period for carrying out their assessment with the aim of determining reasonably the level of the military pilot professional suitability. This makes it possible to timely prevent the negative changes in the state of health and professionally important qualities of pilots in order to support and rehabilitate their readiness for performing the tasks assigned. When carrying out the investigation we managed to take into account the external criteria of success rate in performing the professional duties of pilots: the efficiency of professional activities, the pilot’s qualification and total flight hours. The authors also reveal the difference in the correlation of psychophysiological functions in pilots suitable and unsuitable for performing their professional duties. The authors suggest the up-to-date methodical approaches to monitoring the psychophysiological qualities with the aim of the further development on this basis the criteria for the professional suitability of the pilot. Special solution rules of determining the level of suitability of military pilots for performing their professional duties are developed.

Algorithmic trading for a buy-sell platform: study and comparison

With the high-paced change in the world, the market trends are changing fast and so do the technological innovations. The market is constantly moving and being affected by a number of external factors, making it difficult for investors to make decision. To solve this problem, a technique called Algorithmic Trading is being implemented widely. It refers to use of computer algorithms to make trading decisions without human intervention. In this paper, the algorithm used to predict the stock prices is the LSTM model which is a methodology of neural networks.The existing models are less accurate as they do not take technical factors into consideration. LSTM model, having error of only 0.00036%, overcomes this limitation and also takes temporal factor into consideration.

Re-discovering Evolution: A National Literature between Tautology and Renewal

This article attempts to analyze the evolution of literary thinking as a key concept in the systematic study of a national literature. Methodological requirements to describe literary dynamics as completely as possible prompt a rediscovery of the evolutionary principle, which can be characterized both as an open system of meaning-making and a dialectic of the constant and the changeable contingent on the temporal factor. The focus of this paper is on transitional states, borderline phenomena, semantic recoding, the release of new possibilities of a national literature, and explosive points of literary development when artistic discovery is perceived as a breakthrough challenging inertial normativity. The article reconstructs concepts of A. Bergson, G. Gukovsky, and especially Yu. Tynyanov who developed the notion of “literature as a system” in its natural relation to literary evolution.

The feasibility of using solar powered submersible pumps in the State of Kuwait: جَدوى استخدام المَضَخات الغَاطسة العاملة بِالطَاقة الشمْسِية بِدولة الكويت

The research aims to study the extent of the possible benefit from the solar fall falling in the state of Kuwait to operate submersible type pumps and to show the rate of flow of these pumps according to the change of solar radiation taking into account the spatial and temporal factor. The abundance of the area in southern Kuwait was chosen because there is good brightness for this area underground at different depths. As for the temporal factor, the timing of the transition was chosen between two important seasons that start from mid-January to mid-March, which is the period during which the brightness of the sun moves from the intermediate stage to the full brightness stage. The experimental study showed that the pump passes through two stages, the first of which is not operating and responding For the process of drawing if the solar radiation falling on the panels is less than 225 W/ m2, and the second stage occurs a response and operation of the pump gradually if the falling solar radiation is higher than the previous value, as the study showed that there is a large amount of external energy that is not exploited at some times of the day, especially in Sunny days, where the proportions decreased from 4.8 l/ 1000 watt to 1.5 l/ 1000 watt with an increase in the amount of energy from 430 w/ m 2 to 1005 w T/ m 2 The amount of flow fluctuated during the days of the study due to the differences in the sun's brightness and climate change, and the study was conducted using a method of taking periodic, daily and instant measurements, to determine the amount of energy and flow by using a solar radiation measuring device with a storage memory, which is a device for one of the companies that install solar energy panels And easily traded and other devices such as digital voltmeter and clip meter and water meter, the study concluded that the use of submersible pumps powered by solar energy with the presence of special characteristics such as the pump capacity, water depth and degree of brightness.

Mortal random walks on a family of treelike regular fractals with a deep trap

Due to the ubiquitous occurrence of evanescence in many physical, chemical and biological scenarios, mortal random walks that incorporate evanescence explicitly have drawn more and more attention. It has been a hot topic to study mortal random walks on distinct network models. In this paper, we study mortal random walks on T fractal and a family of treelike regular fractals with a trap located at central node (i.e., innermost node). First, with self-similar setting composed of T fractal, initial position of the walker and location of trap, the total trapping probability of the mortal walker reduces to a function of walker’s single-step survival parameter [Formula: see text]. In more detail, the total trapping probability is expressed by the [Formula: see text]th iteration of map (scaling function) of [Formula: see text]. Based on the map, the analytical expression of total trapping probability’s dominant behavior, the mean time to trapping (MFPT) and temporal factor are obtained, which are related to random walk dimension. Last, we extend the analysis to a family of treelike regular fractals. On them, the total trapping probability is still expressed as the [Formula: see text]th iteration of the map scaling [Formula: see text]. Accordingly, dominant behavior of total trapping probability, MFPT and temporal factor are determined analytically. Both analytical results obtained on T fractal and more general treelike regular fractals show that the mean time to trapping and desired random walk dimension can be obtained by tuning the survival probability parameter [Formula: see text]. In summary, the work advances the understanding of mortal random walks on more general deterministic networks.

Routes of offline and online childhood life: event analysis

The article substantiates the expansion of factors of children's mobility and the inclusion of a temporal factor associated with the characteristics of time: age-related debuts of movements, the transformation of individual episodes of activity into group routes, the sequence of development of environmental objects, the influence of the specific historical situation of residence. There are three areаs of movements in independent mobility – intrafamily, extrafamily, and virtual mobility. Based on the author's study in 2018, the temporal characteristics of many events of modern childhood are presented and some forecasts and hypotheses of the relationship between mobility and growing up are described.

Neuroblast-specific open chromatin allows the temporal transcription factor, Hunchback, to bind neuroblast-specific loci

Spatial and temporal cues are required to specify neuronal diversity, but how these cues are integrated in neural progenitors remains unknown. Drosophila progenitors (neuroblasts) are a good model: they are individually identifiable with relevant spatial and temporal transcription factors known. Here we test whether spatial/temporal factors act independently or sequentially in neuroblasts. We used Targeted DamID to identify genomic binding sites of the Hunchback temporal factor in two neuroblasts (NB5-6 and NB7-4) that make different progeny. Hunchback targets were different in each neuroblast, ruling out the independent specification model. Moreover, each neuroblast had distinct open chromatin domains, which correlated with differential Hb-bound loci in each neuroblast. Importantly, the Gsb/Pax3 spatial factor, expressed in NB5-6 but not NB7-4, had genomic binding sites correlated with open chromatin in NB5-6, but not NB7-4. Our data support a model in which early-acting spatial factors like Gsb establish neuroblast-specific open chromatin domains, leading to neuroblast-specific temporal factor binding and the production of different neurons in each neuroblast lineage.

Analysis of temporal variation characteristics on water quality along Code River, Indonesia

Physicals, chemicals, and microbial parameters were analysedalong the Coder River to reveal the temporal influence on water qualitycharacteristics. From December 2017 to March 2018, we collected twice amonth surface water sample at the nine monitored sampling site. Theresults indicate that the temporal factor has a significant impact, particularly in wet and dry seasons, on increasing the chemical oxygendemand (COD), ammonia-nitrogen (NH3-N), total coliform (TC), andfaecal coliform (FC) above the local government standard. Overall, thewater quality in the Code River is mainly influenced by the anthropogenicpollution sources that did not decrease during the dry season because of thelow water flow.
