How Can Transactional Semantics Enhance the Commit Rate of Context-aware Service Composition in Advanced Pervasive Systems?

Context-aware composition of services exhibiting transactional properties poses several challenges. A major challenge is the transactional behavior of candidate services which is subject to perpetual change while the composition is running. Compositions of services displaying transactional properties must be dynamically adapted at run time to cope with context fluctuations. By dynamic adaptation, we refer to the ability to alter the composition behavior in response to changes affecting its execution. We focus on changes impacting the successful commit rate of transactional service composition. This has led us to explore the trail of a flexible homeomorphism between alternative behaviors. We propose a behavioral adaptation approach that adjusts the behavior of transactional compositions of services in a proactive and transparent manner. This strategy is based on the Profiled Task Class concept. A service composition generator has also been developed for the performance evaluation of components implementing the behavioral adaptation strategy in order to identify its impact on the commit rate of CATS compositions.

Genetic Determinacy of the Behavioral Activity of the Silkworm (Bomby xmori L)

Тhe behavioral activity of such an extremely important agricultural object in scientific and practical terms as the silkworm still remains poorly studied. Aims: Сreation of silkworm lines with alternative behaviors to prove the genetic determinacy of the behavioral activity of the silkworm Bombyx mori L. Place and Duration of Study: The work was carried out at the Research Institute of Sericulture in the Laboratory of Genetics and Breeding of the silkworm in 2015-2020. The Ipakchi 1 and Ipakchi 2 breeds widely zoned in Uzbekistan were used as research objects. Methodology and Results: The Ipakchi 1 and Ipakchi 2 breeds widely zoned in Uzbekistan were used as research objects. The breeding of alternative silkworm lines in terms of motor activity was carried out by selecting the most active caterpillars and male butterflies in the "A" -lines (active), and the least active individuals in the "P"-lines (passive). The separation of individuals by motor activity led to their separation by reproductive and biological indicators. The difference between the lines by the average number of eggs in the clutch of the Ipakchi 1 breed in 2018 was 32 eggs, in 2020 already 133 eggs; by the mass of the clutch in 2018 – 25mg, in 2020 – 78mg. The same patterns were observed in the Ipakchi 2 breed. The greatest difference between the "A" and "P" lines was observed in the viability of caterpillars: in 2018 it was 3.2%, in 2020 already 6.9%. Conclusions: Selection of hatched larvae (caterpillars) and male butterflies by the speed of movement to the feed (the larvae) and to the sexual partner (butterflies) leads to the appearance of silkworm lines with alternative forms of motor activity.

The Expression of Religion and Identity in International Funding

Donor preference is a significant component that can either promote or inhibit sustainable development results, yet the involvement of private donors in international development work has not yet been examined in academic literature. Models for integrative negotiation in funding processes have been proposed, but without having the voice of donors present in literature, all previous negotiation models are incomplete because a major party to the negotiation is absent from the model. Conflict analysis and resolution is a new approach that will bring clarity to the role of private donors in international development work and generate integrative solutions for donors to employ in their work should they choose. This phenomenographic study analyzed the content, process, identity, and relational aspects of conflict in private international development projects through the viewpoint of donors. The research goals were to (1) generate understanding about how private donors understand their role in the international development work they fund, (2) ascertain how donors experience conflict in the course of this work, and (3) determine which conflict resolution techniques can be integrated to align their intentions, resources, and outcomes more accurately. The purposive snowball sample was comprised of six donors who fund private international work outside the US. The interrelated culmination of knowledge generated from this study demonstrates a broad landscape of experiences that describe how donors experience conflict and what may motivate them to consider alternative behaviors that can change the course of their work.

Breeding patterns of female prairie voles (Microtus ochrogaster) displaying alternative reproductive tactics

Individuals of either sex may display alternative behaviors to obtain copulations, but few studies have examined the breeding patterns of females and males in populations where individuals of both sexes exhibit alternative reproductive tactics (ARTs). In prairie voles (Microtus ochrogaster), most adults are territorial, residing at a single nest site either as male–female pairs or as solitary individuals. However, some adults adopt nonterritorial, wandering tactics. During two field seasons monitoring prairie vole populations maintained in seminatural enclosures, we found evidence that females exhibiting different ARTs bred differentially with resident and wandering males. Females residing at a nest with a male bred significantly more often with a paired resident male, primarily their social partner, and significantly less often with male wanderers compared to single resident females or wandering females. These patterns were not due to chance, because paired resident females produced offspring with paired resident males significantly more than expected based on the relative abundance of these males in the population, whereas single resident females produced offspring with male wanderers significantly more than expected based on the proportion of male wanderers in the population. We did not find any evidence that multiple paternity was greater in the litters of single resident females and wanderer females even though these females lacked a male social partner to limit mating access by multiple males. This suggests that mate guarding by a female’s male social partner was not the primary determinant of multiple paternity in the litters of females exhibiting different reproductive tactics. However, male ART did affect the likelihood of multiple paternity. Females that produced offspring with single resident or wanderer males had an increased likelihood of multiple paternity relative to females producing offspring with paired resident males. The results of this study show that female and male ARTs can affect breeding patterns.

Semantics-Driven Programming of Self-Adaptive Reactive Systems

In recent years, new classes of highly dynamic, complex systems are gaining momentum. These classes include, but are not limited to IoT, smart cities, cyber-physical systems and sensor networks. These systems are characterized by the need to express behaviors driven by external and/or internal changes, i.e. they are reactive and context-aware. A desirable design feature of these systems is the ability of adapting their behavior to environment changes. In this paper, we propose an approach to support adaptive, reactive systems based on semantic runtime representations of their context, enabling the selection of equivalent behaviors, i.e. behaviors that have the same effect on the environment. The context representation and the related knowledge are managed by an engine designed according to a reference architecture and programmable through a declarative definition of sensors and actuators. The knowledge base of sensors and actuators (hosted by an RDF triplestore) is bound to the real world by grounding semantic elements to physical devices via REST APIs. The proposed architecture along with the defined ontology tries to address the main problems of dynamically re-configurable systems by exploiting a declarative, queryable approach to enable runtime reconfiguration with the help of (a) semantics to support discovery in heterogeneous environment, (b) composition logic to define alternative behaviors for variation points, (c) bi-causal connection life-cycle to avoid dangling links with the external environment. The proposal is validated in a case study aimed at designing an edge node for smart buildings dedicated to cultural heritage preservation.

THE EFFECT OF TRADE BRANDS ON PURCHASE DECISIONS ON HONDA MOTORS IN PT ABADI MOTOR INDONESIA

Trademarks will be a source of competitiveness that can last a long time and can be a producer of cash flow for the company in the long run. Products that have strong brands will be difficult to imitate because consumers' perceptions of value or certain brands will not be easy to create. Brands are signs in the form of images, names, words, letters, numbers of color arrangements, or a combination of these elements which has a distinguishing power and is used in the trading of goods and services. Whereas purchasing decisions are a process of integration that combines knowledge to evaluate two or more alternative behaviors and choose one of them. The method in this study uses the field reserch method to obtain primary data in the form of observations, interviews and questionnaires and the library reserch method to obtain secondary data in the form of library data from scientific works, thesis, thesis, dissertation and books relevant to the research title. The purpose of this research is to find out whether there is a trademark influence on purchasing decisions of Honda motorcycles. The results of his research are: For simple linear regression analysis the results are: b = 0.43, a = 18.28, then Y = 18.28 + 0.43 X. Correlation Test, the result: r = 0.56. The results of the coefficient of determination analysis = r2 = 31.36%. Hypothesis testing is to find out the significance of the trademark influence on purchasing decisions, namely the results t count = 2.866, as for t table with an error rate of 5% (0.05) sample of 20 people and the result is t table = 2.101, then t count is greater than t table then Ha is accepted and H0 is rejected, which means there is a significant influence between the trademark on the purchase decision of Honda motorcycles at PT Abadi motor, Indonesia.

Behavioral diversity is maintained by a conditional strategy in a freshwater zooplankton

Many populations have intraspecific diversity in phenotype and ecological strategy, but the mechanisms maintaining such diversity are not fully understood. Multiple behaviors can be maintained either as a conditional strategy, where fitness depends on an individual’s phenotype, or as a mixed strategy, where alternative behaviors have similar fitness independent of phenotype. Using high-resolution depth and time sampling, we characterize 2 distinct diel vertical migration behaviors in a population of freshwater zooplankton (Daphnia pulicaria). Individuals in this population differ in their color phenotype and migratory behavior with red morphs upregulating hemoglobin and undergoing a deep migration and pale morphs not producing hemoglobin and undergoing a shallow migration. We experimentally manipulated the behavior of each phenotype in the field and measured population growth in their natural migration behavior as well as population growth in their alternative behaviors. Experimental populations of pale and red morphs under their natural migrations had roughly equal fitness, despite vast differences in environmental conditions. When forced to switch behaviors, pale morphs suffered reduced fitness, whereas red morphs had similar fitness compared with their natural migration. Our results suggest that although behavioral diversity may be promoted by the opportunity for alternative behaviors of equal fitness, the distinct physiological conditions required for survival in alternative behaviors limit the capacity for individual behavioral switching and likely maintain behavioral diversity as a conditional strategy.
