Nowadays every aspect of humans' life, including education, is affected by technological advancements. Given this, teaching and learning have gone through various changes and are now space- and time-independent in the sense that they can happen at any time anywhere. MALL as a type of IT-based instruction has been popular in many developed countries, while in the developing countries the attitude and requirements for its implementation are not yet ready. In the present chapter, an attempt has been made to review the definition of MALL, synchronous/asynchronous learning, learners' perception of MALL, the status of MALL in developed and developing countries, and finally the challenges facing developing countries for implementing MALL in their educational systems. It also tries to give an insight into the cross-cultural differences affecting the use and implementation of MALL and admits there are further avenues to explore variables mediating the application of new technologies in different cultural settings. In the end, some solutions and recommendations for future research are offered.

A popular point in the last 20 years in academic and business settings is well-being at work that is in line with positive psychology, through which one can understand how to make working conditions enjoyable. Alternatively, teaching has been recognized as the most stressful career. Although, not many studies in the form of review have been carried out to focus on the notion of the well-being of teachers in English as a second language (ESL) or English as a foreign language (EFL). According to the literature review, the definition of this construct, the factors related to it, and the empirical studies in this domain are presented. In conclusion, the implications of well-being for teachers, school principals, teacher-trainers, and future researchers are provided, and new directions for future research are delineated.

Abstract Based on matter-element and extension set theories, a novel evaluation method of colleges pioneering education quality is proposed. According to the actual situation of the school, the model of matter-element for pioneering education is established on the ideal of multi-factor optimization integration; pioneering education quality is evaluated by qualitative means based on the matterelement theory and quantitative means based on dependent function. Proposed method not only formally describes the status of the various effecting factors of pioneering education, but also gives an accurate evaluation of the pioneering education quality. In order to verify the validity and feasibility of proposed method, a college’ pioneering education is assessed as example.

This article provides an introduction and overview of the inerter concept and device. Careful attention is given to the distinction between the inerter as an ideal modeling element and devices that approximate the ideal behavior. The background is given to the formal definition of the inerter as a mechanical one-port with terminal forces proportional to the relative acceleration between them. Four major methods of construction are described and modeled. The discussion focuses particularly on the notion of terminals, the distinction between a device and an effect, sign reversals, back driving in geared systems, the conceptual aspects of the modeling step for inerter embodiments, and the problem of reverse engineering to discover a purpose. The article includes an analysis and discussion of the rotational inerter, a brief review of the ideas of passive network synthesis that led to the inerter concept, and an analysis and discussion of several examples of integrated mechanical devices. It concludes with an imaginary dialogue between the author and an interlocutor on the understanding and purpose of the inerter.

The scope of the Theory of Scientific Change (TSC) encompasses any and all changes that occur in a given scientific mosaic, the set of all methods employed and theories accepted at a given time by a given scientific community. Currently, theory is defined as a set of propositions that attempts to describe something. This definition excludes normative propositions from the scope of the TSC. Normative theories, such as those of methodology or ethics, have been excluded since including them appears to give rise to a destructive paradox first identified by Joel Burkholder. There are many historical cases where employed scientific methods are known to conflict with professed methodologies. This seems to violate the third and zeroth laws of scientific change. By the third law, employed methods are deducible from accepted theories. But, this seems impossible in cases where methodologies and methods conflict. Under the zeroth law, all elements in the scientific mosaic are compatible with one another. But, that seems to be clearly not the case if methodologies and methods conflict with one another. In this paper, I argue that normative propositions such as methodologies can be included in the scientific mosaic as accepted theories without generating a paradox and that neither the third nor zeroth laws of scientific change need be violated. I outline my solution to the paradox of normative theories and conclude by describing some new and exciting avenues for future research that are now open.Suggested Modifications[Sciento-2016-0001]: Accept the following reformulation of the third law:The third law ≡ a method becomes employed only when it is deducible from some subset of other employed methods and accepted theories of the time. Consequently, accept that there is no paradox of normative theories: when an employed method and an accepted methodology are logically inconsistent with one another; it merely indicates that the employed method isn’t a logical consequence of the accepted methodology. By the third law, the employed method still follows from some accepted theories, but not from this particular methodology.  Reject the previous formulation of the third law; it can remain in use for educational purposes. [Sciento-2016-0002]: Provided that the preceding modification [Sciento-2016-0001] is accepted, accept the following taxonomy for theory, descriptive theory, normative theory, and methodology:Theory ≡ a set of propositions.Descriptive theory ≡ a theory that attempts to describe something.Normative theory ≡ a theory that attempts to prescribe something. Methodology ≡ a normative theory that prescribes the rules which ought to be employed in theory assessment.Modify the definition of theory acceptance to make it possible for both descriptive and normative theories to be accepted:Theory Acceptance ≡ a theory is said to be accepted if it is taken as the best available description or prescription of its object. Reject the previous definitions of theory, methodology, and theory acceptance.

Abstract:In 1987, the American Rheumatism Association issued a set of criteria for the classification of rheumatoid arthritis (RA) to provide a uniform definition of RA patients. Fuzzy set theory and fuzzy logic were used to transform this set of criteria into a diagnostic tool that offers diagnoses at different levels of confidence: a definite level, which was consistent with the original criteria definition, as well as several possible and superdefinite levels. Two fuzzy models and a reference model which provided results at a definite level only were applied to 292 clinical cases from a hospital for rheumatic diseases. At the definite level, all models yielded a sensitivity rate of 72.6% and a specificity rate of 87.0%. Sensitivity and specificity rates at the possible levels ranged from 73.3% to 85.6% and from 83.6% to 87.0%. At the superdefinite levels, sensitivity rates ranged from 39.0% to 63.7% and specificity rates from 90.4% to 95.2%. Fuzzy techniques were helpful to add flexibility to preexisting diagnostic criteria in order to obtain diagnoses at the desired level of confidence.

Background: Widespread social paradigms on which the status variances are grounded in any society, gender plays pivotal role in manifestation of mental health problems (Rutter, 2007). A hefty volume of research has addressed the issue in adults nonetheless, little is vividly known about the role of gender in adolescent psychopathology. Sample: A sample of 240 adolescents (125 boys, 115 girls) aging 12-18 years was amassed from various secondary schools of Islamabad with the approval of the Federal Directorate of Education (FDE), relevant authorities of the schools and the adolescents themselves. Instruments: Taylor Manifest Anxiety Scale (Taylor & Spence, 1953) and Children’s Negative Cognitive Errors Questionnaire (CNCEQ) by Leitenberg et al., (1986) were applied in present study. Results: Multiple regression analysis revealed that cognitive errors jointly accounted for 78% of variance in predicting anxiety among adolescents. Findings also exhibited that gender significantly moderated the relationship between cognitive errors and adolescent anxiety. Implications of the findings are discoursed for future research and clinical practice.

Background: Severe asthma is a heterogeneous disease that consists of various phenotypes driven by different pathways. Associated with significant morbidity, an important negative impact on the quality of life of patients, and increased health care costs, severe asthma represents a challenge for the clinician. With the introduction of various antibodies that target type 2 inflammation (T2) pathways, severe asthma therapy is gradually moving to a personalized medicine approach. Objective: The purpose of this review was to emphasize the important role of personalized medicine in adult severe asthma management. Methods: An extensive research was conducted in medical literature data bases by applying terms such as “severe asthma” associated with “structured approach,” “comorbidities,” “biomarkers,” “phenotypes/endotypes,” and “biologic therapies.” Results: The management of severe asthma starts with a structured approach to confirm the diagnosis, assess the adherence to medications and identify confounding factors and comorbidities. The definition of phenotypes or endotypes (phenotypes defined by mechanisms and identified through biomarkers) is an important step toward the use of personalized medicine in asthma. Severe allergic and nonallergic eosinophilic asthma are two defined T2 phenotypes for which there are efficacious targeted biologic therapies currently available. Non-T2 phenotype remains to be characterized, and less efficient target therapy exists. Conclusion: Despite important progress in applying personalized medicine to severe asthma, especially in T2 inflammatory phenotypes, future research is needed to find valid biomarkers predictive for the response to available biologic therapies to develop more effective therapies in non-T2 phenotype.
