Degree Of Compatibility Research Articles

APPLICATION OF PSYCHOHYGIENIC MEASURES TO OPTIMIZE LEARNING CONDITIONS

One of the most important conditions for successful student learning and mastering professional competencies is the socio-cultural environment that is developed in the student collective body. The article deals with the current problem of interaction and mutual understanding in the student environment of a higher medical school. The purpose of the study is to determine the indicators of team building and assessment of the psychological microclimate in student academic groups to develop measures to optimize the conditions of their learning. Studies of interpersonal relationships have been provided in academic groups among medical students of Dnipro State Medical University, using a sociometric method (anonymous surveys of students). The results allowed identifying the degree of sociability in groups according to the level of personal compatibility, true leaders, the number of conflicts in groups, their characteristics etc. The analysis of the obtained data not only testifies to the most favourable degree of interpersonal compatibility in student groups, but also presents a range of some interpersonalrelation problems. It necessitates the development and implementation of measures to form a preventive educational space as a prerequisite for effective professional training. An important component of the results is the definition of the psychological “portrait” of the student in the microenvironment, which allows predicting his personal potential for further consideration in professional selection in future educational, social and scientific activities.

Implementasi Fuzzy Multi Criteria Decision Making Pada Seleksi Beasiswa Bank Indonesia

The Bank Indonesia Scholarship is a scholarship provided by Bank Indonesia for students at various universities, one of which is UIN Maulana Malik Ibrahim Malang. In the scholarship selection process, there are several criteria that affect the graduation of prospective scholarship recipients. However, often the process is not transparently. So a calculation method is needed, one of which is using Fuzzy Multi Criteria Decision Making (FMCDM). With FMCDM it can help to get an accurate and optimal decision on scholarship recipients. The FMCDM process begins with collecting information related to scholarships, scholarship applicants, and a set of criteria that will be used for consideration of scholarship acceptance. The set of criteria consists of 11 criteria, namely, Academic Achievement Index (GPA), international level achievement, national level achievement, provincial level achievement, district/city level achievement, father's occupation, mother's income, number of family dependents, house area, land and building tax, as well as electricity bills. The next step is to evaluate the fuzzy set by aggregating the weight of the criteria and the degree of compatibility of each alternative with the criteria. The aggregation result is called the fuzzy fit index which consists of 3 values, namely, the y value which represents the lower limit of the aggregation result, the q value which represents the middle limit, and the z value which represents the upper limit value. The three values are ranked using a ranking method for fuzzy numbers with a degree of optimism. So that the total integral value for each alternative will be obtained, which will be the decision in accepting the scholarship. From the results of the FMCDM, there is a ranking of decision alternatives from the highest priority to the lowest in determining scholarship acceptance.

Infectious Salmon Anemia Virus Infectivity Is Determined by Multiple Segments with an Important Contribution from Segment 5.

Infectious salmon anemia virus (ISAV) is the etiological agent of infectious salmon anemia. It belongs to the genus isavirus, one of the genera of the Orthomyxoviridae family, as does Influenzavirus A. The ISAV genome comprises eight negative-sense single-stranded RNA segments that code for at least 10 proteins. Although some ISAV strains can reach 100% mortality rates, the factors that determine isavirus infectivity remain unknown. However, some studies suggest that segments 5 and 6 are responsible for the different degrees of virulence and infectivity among ISAV subtypes, unlike the influenza A virus, where most segments are involved in the virus infectivity. In this work, synthetic reassortant viruses for the eight segments of ISAV were generated by reverse genetics, combining a highly virulent virus, ISAV 752_09 (HPR7b), and an avirulent strain, SK779/06 (HPR0). We characterized the rescued viruses and their capacity to replicate and infect different cell lines, produce plaques in ASK cells, and their ability to induce and modulate the cellular immune response in vitro. Our results show that the majority of ISAV segments are involved in at least one of the analyzed characteristics, segment 5 being one of the most important, allowing HPR0 viruses, among other things, to produce plaques and replicate in CHSE-214 cells. We determined that segments 5 and 6 participate in different stages of the viral cycle, and their compatibility is critical for viral infection. Additionally, we demonstrated that segment 2 can modulate the cellular immune response. Our results indicate a high degree of genetic compatibility between the genomic segments of HPR7b and HPR0, representing a latent risk of reassortant that would give rise to a new virus with an unknown phenotype.

Fabrication, characterization and antifungal evaluation of polyphenolic extract activated keratin starch coating on infected tomato fruits

In recent times, the application of protein-based bio-composite edible films in postharvest preservation of food and agricultural products is attracting increased attention due to their biodegradability, eco-friendliness and sustainability. In this study, an avocado pear peel polyphenolic extract enriched keratin-starch composite film was fabricated, characterized and evaluated for antimicrobial activity against fungal infected tomato fruits after 6 days of storage at room (25 ± 2 °C) temperature. The SEM/EDX and FTIR results revealed the successful film formation with high degree of compatibility and homogeneity. Following a 6-day post-coating loss in weight of the coated tomato fruits decreased significantly (p < 0.05) with increasing extract concentration while titratable acidity showed a significant (p < 0.05) increase with increasing extract load. Ascorbic acid and lycopene contents were significantly (p < 0.05) higher in the avocado pear peel polyphenolic extract-loaded films. No significant effect was observed in catechol oxidase activity of the tomato extract across the different treatment groups. In addition, fungal growth inhibition showed a dose dependent increase consistent with avocado pear peel polyphenolic load in coated tomato fruits compared to control. Results obtained in this study showed that polyphenolic activated keratin-starch coating was able to reduce spoilage-induce weight loss as well as conserve the overall quality (including titratable acid levels, lycopene and ascorbic acid contents) of fungal-infected tomato fruit and reduce microbial growth. Therefore polyphenolic activated keratin-starch coating could serve as a sustainable and ecofriendly postharvest preservation method to prolong the shelf life of tomato fruits.

Buddy Stacks: Protecting Return Addresses with Efficient Thread-Local Storage and Runtime Re-Randomization

Shadow stacks play an important role in protecting return addresses to mitigate ROP attacks. Parallel shadow stacks, which shadow the call stack of each thread at the same constant offset for all threads, are known not to support multi-threading well. On the other hand, compact shadow stacks must maintain a separate shadow stack pointer in thread-local storage (TLS) , which can be implemented in terms of a register or the per-thread Thread-Control-Block (TCB) , suffering from poor compatibility in the former or high performance overhead in the latter. In addition, shadow stacks are vulnerable to information disclosure attacks. In this paper, we propose to mitigate ROP attacks for single- and multi-threaded server programs running on general-purpose computing systems by using a novel stack layout, called a buddy stack (referred to as Bustk ), that is highly performant, compatible with existing code, and provides meaningful security. These goals are met due to three novel design aspects in Bustk . First, Bustk places a parallel shadow stack just below a thread’s call stack (as each other’s buddies allocated together), avoiding the need to maintain a separate shadow stack pointer and making it now well-suited for multi-threading. Second, Bustk uses an efficient stack-based thread-local storage mechanism, denoted STK-TLS , to store thread-specific metadata in two TLS sections just below the shadow stack in dual redundancy (as each other’s buddies), so that both can be accessed and updated in a lightweight manner from the call stack pointer rsp alone. Finally, Bustk re-randomizes continuously (on the order of milliseconds) the return addresses on the shadow stack by using a new microsecond-level runtime re-randomization technique, denoted STK-MSR . This mechanism aims to obsolete leaked information, making it extremely unlikely for the attacker to hijack return addresses, particularly against a server program that sits often tens of milliseconds away from the attacker. Our evaluation using web servers, Nginx and Apache Httpd , shows that Bustk works well in terms of performance, compatibility, and security provided, with its parallel shadow stacks incurring acceptable memory overhead for real-world applications and its STK-TLS mechanism costing only two pages per thread. In particular, Bustk can protect the Nginx and Apache servers with an adaptive 1-ms re-randomization policy (without observable overheads when IO is intensive, with about 17,000 requests per second). In addition, we have also evaluated Bustk using other non-server applications, Firefox , Python , LLVM , JDK and SPEC CPU2006 , to demonstrate further the same degree of performance and compatibility provided, but the protection provided for, say, browsers, is weaker (since network-access delays can no longer be assumed).

Correspondance between the attitudes of the basic stage students and the methods used in teaching

This study addresses the correspondence between the primary level students' attitudes towards methods used by teachers in the delivery of knowledge and teaching in schools. The great changes in the various fields of modern life due to the broad flow of information, knowledge and experience through the mechanisms that produce a stimulating and engaging ways, and interaction of many segments of the society including primary schools students, have affected individuals' growth and social normalization. These processes have influenced patterns of behaviour, and evoked students' attitudes towards teaching methods and conducting knowledge. Based on this exposition this study aimed to determine the extent of suitable teaching methods used in Sudanese primary schools from students' and teachers' perspective, the factors affecting the attitudes of primary level students in academic achievement, the achievement of the purposes of education, and the mostly desired procedures for attaining a degree of compatibility and adaptability for the benefit of the educational process. The descriptive approach was used to describe and analyze research data. The study worked to achieve those goals through a stratified random sample of 96 teachers and students with a size of 480 individuals from 24 schools for girls in Khartoum North Locality, and has reached to a number of conclusions such as: that the urban environment of students shapes their attitudes and builds preferences, whether in the methods of receiving knowledge or in social relations between school groups, there is also an advantage and approval for the learning aids that are brought by the family at home or used in kindergarten over those used in school, and that the means used in teaching must keep pace with changes in students’ community.

The choice of network compatibility in two-sided markets

ABSTRACT I consider a duopolistic platform competition in which (i) platforms are viewed as heterogeneous by both groups of agents, and sellers can choose multiple platforms; (ii) buyers have a network benefit from their own platform, and a partial network benefit from platform compatibility; and (iii) platforms determine the degree of network compatibility by Nash bargaining. In symmetric equilibrium, the degree of network compatibility increases when the degree of network effect increases or the degree of differentiation of the platform for sellers decreases. Moreover, it is excessive from a social planner’s viewpoint, and incompatibility is desirable for consumers.

Self- and Cross-Pollination in Argane Tree and their Implications on Breeding Programs.

The argane tree (Argania spinosa L.) is a mostly self-incompatible species that must be cross-pollination. However, the cross-pollination is often insufficient to obtain a desirable fruit yield in the absence of compatibility between the orchard’s argane trees. Proper pollination design is therefore essential to ensure a supply of compatible pollen. In this study, pollen germination and pollen development following cross- and self-pollination were investigated in A. spinosa. The choice of compatible parents or a pollinizer is currently a new research topic for the production of argane fruits in the framework of argane farming programs. Different pollination experiments were designed with two main objectives: (i) to study cross/self-(in)compatibility in the argane tree, and (ii) to determine the degree of compatibility between selected superior genotypes for pollination strategies to improve fruit set in argane orchards. Thus, to determine if a pollination deficit exists, experiments were carried out on 14 genotypes, and 5421 flowers served as sampling. The germination rate of pollen was lower than 50% for three genotypes, and only four genotypes bloom twice a year. From cross-pollination trials, traits related to the mother trees, such as the shape of the fruit and fruit ripening duration, are not influenced by the gene flow transmitted by pollens. Self-pollination was very low (0.2%) for both hand- and free self-pollination but the highest fruit set rate observed was 5.3%. Based on the pollen effect study results, it can be concluded that different pollen sources affected the fruit set. Thus, the choice of an efficient pollinizer genotype must be inter-compatible with the main variety, bloom at the same time, and be regular (no alternation). This is the first time that a pollinizer tree was reported and studied for argane. To meet future argane farming requirements, the number and location of compatible pollinizers is very important in the argane orchard design. This design of pollination remains to be checked by alternately planting a row of pollinizer trees or inter-rows with main varieties.

Identifying Spatial Matching between the Supply and Demand of Medical Resource and Accessing Carrying Capacity: A Case Study of Shenzhen, China.

Previous Studies, such as the evaluation of the supply of and demand for regional medical resources and carrying capacity assessments, require further development. This paper aims to evaluate the carrying capacity and spatial distribution of medical resources in Shenzhen from the perspective of supply and demand, and to conduct a time-series variation of the coupling coordination degree from 1986 to 2019. The two-step floating catchment area method was employed to quantify the carrying capacity and coupling coordination degree method and spatial autocorrelation analysis were applied to analyze spatial distribution between supply and demand. The results were as follows. (1) The carrying capacity index in more than 50% of the districts was classified as low-grade. The percentage of regions with good grades was 8.27%. The regions with a high carrying capacity were distributed in the central and southeastern areas. (2) The coupling coordination continued to rise, increasing from 0.03397 in 1986 to 0.33627 in 2019. (3) The level of supply and demand for medical resources in Shenzhen increased from 1986 to 2019, and the highest degree of compatibility between the supply and the population size was largely concentrated in the western and eastern regions. This research can provide a theoretical reference for Shenzhen to rationally plan medical resources and improve the carrying capacity of medical resources.

Challenges in the Integration of Quality and Innovation Management Systems

Seeking to reduce the number of inconsistencies in their processes, many organisations choose to implement the ISO 9001:2015 quality management standard. Their aim is to improve operational performance while, at the same time, they cope with increased pressures from the market to present innovative products and solutions and from the stakeholders to implement new organizational methods. This work intends to investigate how organisations can leverage ISO 9001:2015 in implementing the ISO 56002:2019 innovation management standard, given that both standards have a high degree of compatibility with each other. For that purpose, meetings were held with senior managers and quality managers of three Portuguese SMEs to discuss the existing potential challenges and gaps in the integration of both management systems. The results point to the existence of a significant set of practices in the field of quality that can support and facilitate the formalization of integrated management systems. Nevertheless, generalization of the results should be avoided, and more research is needed, since the integration of management systems is often conditioned by cost and time related issues. Furthermore, it is disputable whether a company can simultaneously reach a high level of efficiency (brought about by implementing a quality management system) and a high level of innovation (made possible by the implementation of an innovation management system) thus jeopardizing the implementation of an integrated management system.

Seagrass- and wood-based cement boards: A comparative study in terms of physico-mechanical and structural properties

The inclusion and management of local, natural resources in the construction sector are on the rise as a result of the undisputed essentiality of sustainability. This study aims to assess and compare cement-bonded boards containing seagrass fibers (Posidonia oceanica) and pine wood particles (Pinus sylvestris) in terms of their compatibility with cement, their physico-mechanical properties, and their microstructure using X-ray micro-computed tomography and 3D-reflected light microscopy. Seagrass-based cement boards comply with the DIN EN 634 surpassing the stated MOR value of 9 N mm−2. The thickness swelling of all seagrass-based cement boards was between 0.2 and 1.2%, indicating a possible outdoor application. The structural characterization and the study of the degree of compatibility showed that the size, geometry, and chemical composition of the lignocellulosic precursors mostly influenced the final properties of the board. Seagrass-based cement boards provide novel possibilities to use new environmentally friendly materials for construction applications.

A radical-radical cross-coupling reaction of xanthene with sulfonyl hydrazides: facile access to xanthen-9-sulfone derivatives.

A straightforward strategy for direct incorporation of sulfonyl units into a xanthene moiety for accessing xanthen-9-sulfone derivatives in good to excellent yields has been established via metal-free radical-radical cross-coupling reaction of xanthenes and sulfonyl hydrazides. Using easily accessible starting materials, this methodology proceeds efficiently with a high degree of functional group compatibility and with a wide scope of both xanthenes and sulfonyl hydrazides under operationally simple reaction conditions. Mechanistic investigations revealed that sulfonyl radicals could be generated from sulfonyl hydrazides in the presence of TBHP under an oxygen atmosphere.

Особливості вивчення та формування позитивного психологічного клімату спортивної команди

The article is devoted to the study of the problem of studying and forming a positive psychological climate of the sports team, which is one of the main factors in achieving high sports results. The aim of the article is to analyze the scientific and methodological literature on the problem of research and identify components that affect the formation of the psychological climate of the sports team, as well as methods and techniques of research on this issue. one of the possible ways to diagnose interpersonal relationships is to identify those individual qualities and properties that affect the relationship itself. The verbal scales we used to identify one or another property confirmed that high sports results are due to the favorable psychological climate in the team and a high degree of compatibility of its members. We considered the compatibility of members of the sports team on three levels: social, psychological and psychophysiological. In the process of each, including sports activities, relationships, traditions, habits, feelings are established between people, which directly or indirectly affect its effectiveness. These processes are called the psychological climate, which is formed in sports under the influence of various objective and subjective factors: success, age, feelings, moods, motives, needs and relationships between athletes, as well as under the influence of purposeful pedagogical work of the coach. The sphere of interpersonal relationships in a sports team is extremely wide, they have a complex structure, permeate different levels of organization of personality. Therefore, with the help of one, even well-designed test, it is impossible to fully reveal human relationships. Here it is necessary to use a comprehensive analysis of the individual and the team as a whole. The demand of society for attention to the psychological comfort of being in a professional environment is extremely high.

Usklađenost POCT metode sa potpuno automatizovanom metodom za određivanje HbA1c

Previous research suggests that point-of-care (POCT) determination of glycated hemoglobin (HbA1c) is a diagnostic test that can be an adequate alternative to measuring HbA1c in the laboratory. The main goal of this study was to examine the analytical characteristics of the novel INCLIX POCT method for HbA1c determination in order to test its performance before introducing this method into routine use. HbA1c is measured in a duplicate in 44 EDTA blood samples parallel on INCLIX POCT device (Sugitech, Inc.) and using automated turbidimetric immunoinhibition test on Olympus AU400 (Beckman Coulter). The within run imprecision was 7.58%, between runs imprecision was 6.63% and 6.22%, and day-to-day imprecision was 8.80% and 7.51%. Total laboratory imprecision was in agreement with those stated by the manufacturer. A statistically significant Pearson correlation coefficient was calculated (r = 0.871, P &lt; 0.01; linear R2 = 0.757). Using Deming regression analysis, the following equation was obtained: y = - 1.80 + 1.304x. Our results indicate statistically significant correlation, linear relationship, and a significant degree of compatibility between the two analyzed methods. However, the negative bias of the HbA1c values determined on the POCT analyzer compared to the Olympus AU400 was confirmed, highlighting the need to standardize the INCLIX method.

Desempenho fisiológico e químico da cultivar de videira Flame sem sementes na presença de Paulsen 1103 como enxerto intermediário

ABSTRACT Interstock is commonly used in deciduous fruit trees as a sustainable strategy to reduce the vigor of the scion associated with the high quality of fruits. In this study, we tested the effect of Paulsen 1103 (Vitis berlandieri x Vitis rupestris) as interstock on the grafting success, growth, and the physiological and chemical parameters of Flame seedless (Vitis vinifera) grapevine grafted onto Freedom (Vitis champinii x 1613C) and Paulsen 1103 rootstocks. This study was conducted over two seasons (2019 and 2020). The results indicated that direct grafting on the Paulsen 1103 rootstock recorded the highest grafting success percentage. Moreover, the grafting success percentage increased significantly when Paulsen 1103 was used as interstock between Flame seedless and Freedom rootstock (FI/P/Fr) compared to the grafting success without Paulsen 1103 interstock (FI/Fr). Also, using Paulsen 1103 as interstock between Flame seedless scion and Freedom rootstock (FI/P/Fr) significantly reduced the morphological parameters (shoot length, leaf area and the dry weight of shoots and roots) and physiological parameters of leaf (relative water content, transpiration rate, and stomatal conductance) but significantly increased the leaf chemical content (peroxidase activity, total phenols, total proline, and total soluble sugar content) compared to values of the parameters measured in Flame seedless grafted onto Freedom rootstock (FI/Fr). Peroxidase activity could be used for predicting the degree of compatibility in grapevine grafts. This study suggested that the effect of Paulsen 1103 interstock on the vegetative growth of scion is correlated with its effect on chemical content and physiological responses of the scion.

PRAGMATIC ANALYSIS OF THE USE OF STYLISTICALLY COLORED LINGUISTIC UNITS IN POLITICAL DISCOURSE: ON THE MATERIAL OF V.V. PUTIN'S SPEECHES

Problem statement. In the proposed paper, we subject to a pragmatic analysis the use of stylistically colored linguistic units in the political discourse of the genre of oral speech: based on the material of television speeches (as meeting and interview) of the President of Russia. The study of colored linguistic units within the framework of political discourse is of particular interest, since these units serve the pragmatics of language. Results. Pragmatic information in political discourse is distributed among all linguistic units. However, stylistically colored linguistic units, by which we mean connotatively saturated words, expressions, phraseological units and aphorisms, carry the greatest pragmatic load. They contribute not only to attracting the attention of the addressee, but also to influencing him. Conclusion.Political discourse, representing a specific and complex type of communication, requires a special approach to its study. The role of stylistically colored linguistic units in the realization of the addressee's speech intention in political discourse is huge. In the course of the study, it was stated that the words, expressions, phraseological units and aphorisms used by the President of Russia are generally evaluative, more precisely, ironic (in particular, there is a fairly frequent use of phraseological units (81.81%), and sometimes stylistically reduced words and expressions (6.06%)). This can be explained by the fact that phraseological units, unlike aphorisms, are carriers of lexical meaning and can act as an equivalent of words. In addition, the degree of compatibility of components in phraseological units is not the same, i.e. they may include non-free, but easily separable words, and be used in a figurative sense. Consequently, they are more easily created in the process of speech, contributing to the achievement of the illocutionary goal of the addressee. Nevertheless, phraseological units and aphorisms, as well as stylistically reduced words, due to their expressiveness, contribute not only to attracting the attention of the addressee, but also to influencing him, while producing a certain pragmatic effect.

РЕГУЛЮВАННЯ СТІЙКОСТІ РІДКИХ МІКРОСТРУМЕНІВ ПОЛІПРОПІЛЕНУ В МАТРИЦІ СПІВПОЛІАМІДУ ЗА РАХУНОК НАНОДОБАВОК

Goal. Investigation of the effect of the concentration of nanoparticles of aluminum oxide (Al2O3) and alumina modified with silver (Ag/Al2O3) on the decomposition kinetics of liquid microjets of polypropylene (PP) in a copolyamide (CPA) matrix and the possibility of controlling the microfibrillar morphology of the PP/CPA blend.Methodology. The components of the blend were mixed on a screw-disk extruder. The kinetics of the disintegration of liquid microjets was studied using a technique based on the theory of destabilization of a liquid cylinder under the action of capillary waves. The degree of dispersion of polypropylene in the matrix was evaluated by photomicrographs of cross sections of the extrudates of the blends.Results. Nanoadditives of the original and silver-modified aluminum oxide with a content of (0.1 ÷ 3.0) wt.% In the blend increase the compatibility of the components: the surface tension (γαβ) in the compositions of all compositions decreases. Ag/Al2O3 nanoparticles are more effective than aluminum oxide nanoparticles - the γαβ value decreases by 9.6 and 5.3 times, respectively, which ensures a high degree of dispersion of the dispersed phase component in the matrix. The disintegration resistance of polypropylene microjets is increasing, as evidenced by a decrease in the instability coefficient (q) and an increase in the microjet lifetime (tl). The curves of q and tl dependence on the additive content have an extreme character. The minimum values of the instability coefficient of microjets and the maximum values of their lifetime are achieved at a nanoparticle concentration corresponding to the lowest interfacial tension.Scientific novelty. The positive effect of the investigated nanoadditives on the kinetics of the decomposition of liquid microjets of polypropylene in the copolyamide matrix has been established. The highest modifying effect in the presence of Ag/Al2O3 nanoparticles is due to their amphiphilic nature, which ensures the predominant localization of nanoparticles at the interface and a synergistic increase in the degree of compatibility in the PP/CPA system.Practical significance. The regularities of increasing the stability of liquid microjets to disintegration in polymer blends filled with nanoparticles have been established, which will make it possible to determine the parameters of the processes of mixing and forming fibers and films, in which the microfibrillar structure arising during the flow of the melt will remain unchanged in the products.

Model of wind energy system with reduced simulation time validated by classical equivalent model developed under Simulink

Models of a wind energy conversion chain using classical Simulink models of a diode bridge exhibit significant simulation time making difficult its combination with large scales optimization approaches. For this purpose and to increase the degree of compatibility of wind turbine models with large scales optimization approaches such as those based on Genetic Algorithms, a wind energy conversion system having an horizontal axis propeller, an axial generator with permanent magnets, recharging a battery energy accumulator through a diode rectifier is modeled by simplified method reducing simulation time. Indeed, a model of the three phase’s diode rectifier making the simulation time considerably reduced compared to the existing model in the Simulink library is developed. This model is validated by comparison with the model using the classic Simulink library. Another objective of this study is the formulation of the useful torque optimization problem having an essential constraint the reduction of the generator phase’s inductance in the goal to reduce the overvoltage in generator phases.

Disability and the Goods of Life.

The so-called Disability Paradox arises from the apparent tension between the popular view that disability leads to low well-being and the relatively high life-satisfaction reports of disabled people. Our aim in this essay is to make some progress toward dissolving this alleged paradox by exploring the relationship between disability and various "goods of life"-that is, components of a life that typically make a person's life go better for them. We focus on four widely recognized goods of life (happiness, rewarding relationships, knowledge, achievement) and four common types of disability (sensory, mobility, intellectual, and social) and systematically examine the extent to which the four disability types are in principle compatible with obtaining the four goods of life. Our findings suggest that there is a high degree of compatibility. This undermines the widespread view that disabilities, by their very nature, substantially limit a person's ability to access the goods of life, and it provides some guidance on how to dissolve the Disability Paradox.

Image steganography using genetic algorithm for cover image selection and embedding

Data interchange through internet becomes an eminent technique and hence data security has become a big challenge in the field of communication with the increased use of internet. Demand for data authentication and effective means to control data integrity has been steadily increasing. Such a demand is due to the ease with which digital data can be tampered. Thus, cryptography and watermarking can be replaced with steganography for secure data communication and data privacy. In this paper, the carrier image is selected such that the payload/secret image and least significant bits of carrier image are matched with larger degree of compatibility and the hiding process introduces negligible changes in the resulted stego image based on genetic algorithm. In the proposed method we have achieved 30 to 40% improvements in the performance when compared to different existing methods. Selection of a suitable cover image and hiding the secret data to enhance the imperceptibility is a very challenging task. Genetic algorithm is used to ease the work of exploring an impossible task of selection from the trillions and millions of combinations.
