Study of Shock-processed Titanium Powder in View the Crystal Structure and Microstructure Dimension
Authors: Ahmad Irshad
Published: November 2019

Titanium powder was rapidly solidified by using shock-wave consolidation technique. The critical parameters were controlled by the instrumented detonics and pin- oscillography. The compacted specimens were investigated for crystal structure and micro structural strengthening by using standard diagnostic techniques. The density of the final product was found to be more than 96% of the theoretical value. X-ray diffraction pattern reveals intact crystalline structure without the presence of any undesired phases. The particle size reduction indicated by XRD was supported by laser diffraction based particle size analyzer. The crystalline structure of the compacted specimen remained intact. No impurity or phase of any other kind was detected. There is no segregation within the compacts. Results from energy dispersive spectroscopy ruled out the possibility of any segregation within the compacts. This high-quenching during rapid solidification minimize chemical segregation and formation of massive phases and hence ensures a homogeneous fine-grained structure. Scanning electron microscopy showed crack-free, voids-free, melt-free, fracture-less compacts of titanium with a unidirectional dendrite orientation without any grain-growth. The particle size of the titanium powder calculated from SEM image found to be ~30μm that supports the earlier observation. Shock-wave consolidation being  transient in nature, owing to its short processing time, controlled  parameters and high quench-rates  proven to be a very helpful technique for obtaining a stable structural and microstrutural products. Hence, SWC technique helped in forming the uniform melt-free, crack-free, voids-free compacts of titanium  powder.

The study was carried out to determine patterns of birds’ species richness, alpha and beta diversities; and abundance in Badingilo national park using a 10 m fixed-radius point count method. A total of 2670 individuals were recorded from 182 points in the park. The highest expected number of species (Jack1 estimator) was observed in the Riverine habitat and least was in the Agriculture and Human settlement habitat type. The total number of species observed in the park was 63; however Jack1 estimator indicated that there were 68 species in the park. The majority of the birds observed during the study were resident species, few migratory and Palaearctic bird species. Few birds observed in the park were abundant. The most abundant species was the village weaver (381 individuals), and the rarest species were black-bellied bustard, barn owl, black scimitar bill and tree pipit (one individual each).

Authors: Yildiz Zehra , Usta Ismail , Kale Bandu Madhukar , Mellen Graham B. , Wang Youjiang
Published: November 2019

In this paper polyester fabrics were pretreated with alkaline solution to improve the ability for the fabric surface to bond with polypyrrole (PPy) coating layer. In situ chemical oxidative polymerization of pyrrole monomer was performed on alkali treated polyester fabrics. Then the fabrics were characterized by FTIR and XRD analysis. The tensile properties of the yarns in both warp and weft directions were measured after alkali treatment and PPy coating processes. The abrasion resistance test was performed on PPy coated fabrics with and without alkali treatment. The surface electrical resistivity of PPy coated fabrics were searched. The electromagnetic shielding effectiveness (EMSE) properties of fabrics in terms of reflection, absorption and transmission behaviors were also investigated. A significant EMSE value increase (about 27%) was obtained with alkali treatment.
Optimal Method for Production of Amorphous Cellulose with Increased Enzymatic Digestibility
Authors: Ioelovich Michael
Published: November 2019

In this paper, a simple and cheap method for producing of amorphous cellulose was studied by treating the initial cellulosic material (MCC and waste paper) with a cold solvent, such as aqueous solution of 7% NaOH/12% Urea, at the various ratios of the solvent to cellulose (v/w) (R). If was found that after treatment of cellulose materials with the solvent at R ≥5, a completely amorphous cellulose (AC) is formed. Due to high digestibility, the AC with concentration of 50 g/L is converted to glucose almost completely for 48 h under the action of cellulolytic enzyme CTec-3 with a dose of 30 mg/g solid sample. Such sample can be used as an amorphous standard in the study of crystallinity degree and enzymatic hydrolysis of various types of cellulose and lignocellulose. It was found that enzymatic saccharification is most advantageous to carry out at elevated concentrations of AC, 150 g /L. Due to high cost of MCC, it is preferable to use a cheap cellulose raw material, such as mixed waste paper (MWP), for the commercial production of AC and glucose. The resulting glucose can find application in biotechnology as a promising nutrient for various microorganisms.
Functional-Material-Based Touch Interfaces for Multidimensional Sensing for Interactive Displays: A Review
Authors: Gao Shuo
Published: November 2019

Multidimensional sensing is a highly desired attribute for allowing human-machine interfaces (HMIs) to perceive various types of information from both users and the environment, thus enabling the advancement of various smart electronics/applications, e.g., smartphones and smart cities. Conventional multidimensional sensing is achieved through the integration of multiple discrete sensors, which introduces issues such as high energy consumption and high circuit complexity. These disadvantages have motivated the widespread use of functional materials for detecting various stimuli at low cost with low power requirements. This work presents an overview of simply structured touch interfaces for multidimensional (x-y location, force and temperature) sensing enabled by piezoelectric, piezoresistive, triboelectric, pyroelectric and thermoelectric materials. For each technology, the mechanism of operation, state-of-the-art designs, merits, and drawbacks are investigated. At the end of the article, the author discusses the challenges limiting the successful applications of functional materials in commercial touch interfaces and corresponding development trends.

English is the most widespread and dominant business language and it has become compulsory for people to speak English if they wish to join a global workforce.A number of research show that business communication is most often conducted i English. Due to its skyrocketing use,a tendency for designing specialized courses which focus more on specific outcomes and industries is observed, especially for English department students. By addressing specific audiences and catering for specific needs,English for Specific Purposes (ESP) is the example of this category.This paper focuses on English for e-Tourism and the teaching strategies which are implemented in order to adjust the course to students’ needs. The emphasis is taken into consideration because the relationship between technology and tourism has become delicate and challenging.  Observations on this inseparable relationship assume a great importance when considering the varied world of tourism activities, where the strict dependence on technology for the efficient and effective management of information has caused a real revolution due to the diffusion of online applications. The most recent developments of the web and social networks have then further accentuated the influence of ICTs (Information and Communication Technologies) on the sector of education. Moreover, the important aspects of English for e-Tourism will be highlighted since the adoption of new technologies has reshaped the entire process of tourism service development as well as the entire tourism industry as a whole. Finally, reference will be made to the responsibilities that both teachers and students have in the ESP framework.
MVSCA: Multi-Valued Sequence Covering Array
Authors: Younis Mohamed Issam
Published: November 2019

This paper discusses the limitation of both Sequence Covering Array (SCA) and Covering Array (CA) for testing reactive system when the order of parameter-values is sensitive. In doing so, this paper proposes a new model to take the sequence values into consideration. Accordingly, by superimposing the CA onto SCA yields another type of combinatorial test suite termed Multi-Valued Sequence Covering Array (MVSCA) in a more generalized form. This superimposing is a challenging process due to NP-Hardness for both SCA and CA. Motivated by such a challenge, this paper presents the MVSCA with a working illustrative example to show the similarities and differences among combinatorial testing methods. Consequently, the MVSCA is a new trend that can be a research vehicle for researchers to develop new and/or modify existing combinatorial strategies to deal with the combinatorial explosion problem raised by the MVSCA.
Demand Priority in a Power System With Wind Power Contribution Load Shedding Scheme Based
Authors: Hassan Yasser falah , Rashid Yasir ghazy , Tuamiah Firas mohammed
Published: November 2019

The load shedding  scheme has been extensively implemented as a fast solution for unbalance conditions. Therefore, it's crucial to investigate supply-demand balancing in order to protect the network from collapsing and to sustain stability as possible, however its implementation is mostly undesirable. One of the solutions to minimize the amount of load shedding is the integration renewable energy  resources, such as wind power, in the electric power generation could contribute significantly to minimizing power cuts as it is ability to positively improving the stability of the electric grid. In this paper propose a method for shedding the load base on the priority demands with incorporating the wind power generated. The higher priority demands are fed with a reliable wind energy resource in order to protect them from shedding under contingency condition such as high overloading by the real time monitoring of the network accompanied with power reducing for the lower priority demands. The simulation results prove effectiveness and practicality of the applied method paving the way for possible applications in power systems.
Thou Dost Not See Me For Who I Am - Theoretical Reflections on the Underutilization of Employee Talents in the Workplace and Its Consequences
Authors: Jessurun Haiko , Weggeman Mathieu , Anthonio Gabriël , Gelper Sarah
Published: November 2019

This
article describes ‘chronic relative underperformance' (CRU), – a
special example of person-environment misfit –, investigates
literature on giftedness, underachievement, underemployment,
workplace boredom and bore-out, and connects these to clinical
psychological views on mentalization, in order to develop thoughts
that are useful in the understanding of why some employees fail to
thrive, even though that they are performing seemingly well enough as
regards to the targets of the employer, with the intention to offer a
frame of reference that can lead to further understanding of this
condition. Relative underperformance is an issue that is hardly
described within the literature. Recognising CRU in the workforce and
taking steps to counter its effects, may lead to a more efficient and
elegant way to reach organisational, and personal, goals.

The material in this paper comprise a compendium of more detailed information and analyses of the 14 large-scale explosions described the paper Mechanisms and Occurrence of Detonations in Vapor Cloud Explosions by Oran, Chamberlain, and Pekalski [Progress in Energy and Combustion Science, doi.org/10.1016/j.pecs.2019.100804). Each section begins with a general description of the incident and then, where possible, more analysis (based on the work of GC) and useful information about the incident. The events all have certain physical similarities, but vary greatly in terms of the level of information available for analysis. Taken together, however, they present a powerful picture of what a detonation can do as well as indications of what might be done in the future to avoid such an incident.

Authors: Economides Marcos , Ranta Kristian , Hilgert Outi , Kelleher Dolores , Arean Patricia , Hoffman Valerie
Published: November 2019

ObjectivesThe objective of this study was to assess whether the Meru Health Program (MHP), a novel, self-guided, structured smartphone-based intervention with asynchronous therapist support, is associated with improvements in occupational impairment and daily functioning in working adults with symptoms of depression and anxiety. MethodsIn this observational, pre-post study, occupational and functional impairment (assessed via the Workplace Performance and Activity Impairment [WPAI] questionnaire) was measured pre- and post-intervention in a real-world sample of employed patients (n = 64) receiving treatment via the MHP for symptoms of mild to moderate depression and/or anxiety (Patient Health Questionnaire-9 item scale [PHQ-9] > 4 and/or Generalized Anxiety Disorder-7 item scale [GAD-7] > 4). ResultsThe MHP was associated with improvements in presenteeism (mean decrease = 12.1, 95% CI = [4.17 – 20.0], p = 0.003; d = 0.56), overall work impairment (mean decrease = 13.4, 95% CI = [5.62 – 21.2], p < 0.001; d = 0.54), and impairment in daily functioning (mean decrease = 14.8, 95% CI = [9.09 – 20.4], p < 0.001; d = 0.60), as well as smaller (non-significant) improvements in absenteeism (mean decrease = 4.32, 95% CI = [-1.00 to 9.64], p = 0.11; d = 0.25). A conservative estimate of annual productivity cost savings associated with the MHP is $6271 per employee, corresponding to a 30% relative improvement in overall work productivity. ConclusionsRemote, smartphone-based interventions such as the MHP may help employees suffering with mild-to-moderate mental health issues function and perform better at work, resulting in cost savings for employers.
Parents, Partners, Plans and Promises: The Relational Work of Student Loan Borrowing
Authors: Stivers Abby , Berman Elizabeth Popp
Published: November 2019

When does student loan borrowing prompt relational work between borrowers and their family members? Research on student loans has focused on quantitative estimation of the effects of borrowing on educational attainment, economic well-being, health, and life course milestones. Drawing on sixty interviews with respondents working as lawyers in the northeastern U.S., we argue that student loans also have underappreciated relational effects, even for relatively privileged borrowers. Relational work around student loans is particularly visible during three important moments: the decision to borrow, the decision to partner, and when planning children’s futures. While scholars have examined the effects of borrowing on marriage and childbearing decisions, they have implicitly assumed that it is difficulty repaying that causes such effects. Attention to relational work, however, shows how debt can create additional burdens even when borrowers have the ability to repay, and may help explain why similar debt levels affect different groups differently.
“We tried to, but life gets in the way”: The Value of Cognitive Interviewing for Testing a Questionnaire on Antibiotic Consumption Behaviours
Authors: Anderson Alistair
Published: November 2019

The public’s perceptions and behaviours regarding antibiotics and antibiotic stewardship are often measured using survey questionnaires. Previous qualitative testing of questionnaire instruments that include questions about antibiotics or drug-resistant infections has suggested that questions on this topic are subject to measurement error for multiple reasons. This study used 13 cognitive interviews with pet owners to identify issues with a questionnaire instrument for a survey examining pet owners’ knowledge and behaviour around antibiotic use both personally and regarding their pets. Key findings from the study are that there are notable differences in quality of recollection between personal and pet-focused antibiotic use, and that socially desirable responding is only applied to certain behaviour questions. This article argues that cognitive interviews can provide substantial benefits as part of mixed-methods social research by supplementing dimension-reduced survey questionnaires with participants’ explanations, narratives, and experiences relating to the survey questions, with further benefits for qualitative theme generation.

Published: November 2019

Mild-Hybrid Electric Vehicles (mild-HEVs) earned market share over the last years an as effective roadmap to limit air pollution in big cities. In addition to this role, hybrid propulsion can be used to avoid dry clutch overheating in mild-HEVs equipped with automated manual transmissions. Indeed, high thermal level could result in serious damaging of dry clutch linings with very fast decay of expected lifespan affecting vehicle reliability. This paper shows results of vehicle launch simulations to highlight how the propulsion due to electric motor can effectively reduce clutch thermal stress during the slipping phase.
The Artist in and of the Work
Authors: Tan Ian
Published: November 2019

This paper will explore the problematic link between biography and literature as it is self-consciously demonstrated by Stephen’s theory about Shakespeare in the ‘Scylla and Charybdis’ episode of James Joyce’s Ulysses. I argue how Stephen’s construction of the link between Shakespeare’s life and his work both illuminates and repeats a larger critical gesture between biography and literature. This is based on a mode of hermeneutical temporality which sees the present moment as containing within itself temporal fullness to be realised in a teleological fashion. However, Joyce’s own ironic construction of Stephen, who disavows his own theorizing, should alert us as to how much we can take this theory at face value with respect to a character who invokes the name of Shakespeare as much to construct a theory of him as to deconstruct it. In response to this, I argue that Rene Girard’s reading of Shakespeare in terms of mimetic desire provides a more compelling picture of the ways in which not only his characters, but the characters in Ulysses understand and articulate sexual desire as mediated by a prior belatedness patterned on the desire of the Other. However, I problematize Girard’s reading of Shakespeare and Joyce, and my final contention is that the desire of reading and self-fashioning is set in motion not so much by mimetic recognition as it is by the Lacanian notion of misrecognition. This forms the discursive conditions of the articulation of that desire while irrevocably fracturing not only the Girardian idea of the triangulation of desire, but also the ‘loop’ of literature and biography by thwarting all attempts to speak and desire from the place of the Other, as the Other.
A Comprehensive Review on the Potential of Microfabricated Microneedles for Effective Systemic Delivery of Drugs
Authors: Adeyemi Temitayo
Published: November 2019

Microneedles are a new technology for percutaneous drug delivery. They are often conveyed in a series of multiple simple microneedles used on the skin to facilitate systemic or topical drug delivery. They are manufactured using various techniques and they could be hollow, solid, coated or polymeric. Although classified as an emerging but expanding field of drug delivery, they are flawed in many ways. This paper will extensively discuss (in the context of skin physiology) the use of microneedles and their feasibility in delivering medication to sites of actions in the body. This paper is a review paper and data were collated from multiple sources including journals and articles. Microneedles show great potential; however, the physiology of the skin poses a great challenge for researches in this field.

Ovarian cancer is one of the top five cancers among female. It is treated with surgery and chemotherapy. Besides the well-known tumor marker CA-125, the treatment response is monitored by radiological imaging. Computed tomography (CT) and magnetic resonance imaging are used to be the primary modalities. With the emergence of positron emission tomography (PET), the detection of residual or recurrence disease can be made more accurate. The fusion of PET/CT has higher sensitivity and specificity.International Journal of Human and Health Sciences Vol. 04 No. 01 January’20 Page : 15-18
Evaluation of Human Resources Planning within the Framework of Turkey’s Health Transformation Program (HTP) with regards to Principles of Justice
Authors: Özdinç Ahmet
Published: November 2019

Objective: Health Transformation Program (HTP) which is a health sector reform began in 2003 in Turkey has changed many parameters within the health sector. In the years when the reform was proposed, it can be said that most of the limitations of the health system are related to the insufficiency of resources and the inability to organize them properly. It is clear that the limitations of human resources, like all resources, bring out the justice problem in distribution. Justice requires fair participation to the resources that will be used in the field of health and fair, honest, and equal distribution of the allocated resource according to needs. Our study will evaluate the human resources policy of the Health Transformation Program in terms of need, equality, utilitarianism, and equity which are the sub-principles of justice.Materials and methods: This research is an example of retrospective study. The health justice principle has been tried to be tested as a new health policy, the Health Transformation Program, was declared in Turkey in 2003 by comparing human resources data between the beginning and end of the process up to 2013. The data acquired in our country will be compared with the data of the world and OECD countries before and after the program. Human resources data will be obtained from the Ministry of Health, State Planning Organization, WHO, WB and OECD.Results and discussion: As a result of the evaluations, it is observed that the principles of justice are generally pursued in the planning and implementation of the Health Transformation Program. On the other hand, it is possible for people to have access to health services according to their needs, as the program claims, by applying the need principle. However, the lack of tangible criteria to determine needs and the ambiguity of the definition of need delimitate the usage of this sub-principle of justice.Conclusion: It is difficult to fully observe the principle of justice in health policies. Fair planning human resources as well as physical resources is significant for both patients and health care workers themselves.International Journal of Human and Health Sciences Vol. 04 No. 01 January’20 Page : 41-50

This study aims to analyze how the relationship between obesity, nutritional status, sleep duration and stress level influence the blood pressure of the night shift nurses.Materials and methods: The subjects in this study were night shift nurses in four hospitals. The dependent variable was blood pressure and the independent variables were nutritional status, sleep duration, and stress levels. This study was an observational analysis with a perspective cohort design in which the subjects were 312 night shift nurses. Nutritional status were identified from Body Mass Index (BMI) through anthropometric measurement, sleep duration by looking at average hours of sleep during the night service, stress levels through the Perceived Stress Scale (PSS-10) questionnaire. Blood pressure was measured using a mercury sphygmomanometer. Data were analyzed by Chi-square test and Logistic Regression.Results and Discussion: There was a significant relationship between nutritional status, sleep duration, and stress levels with blood pressure. The results of the multivariate analysis showed that the shift nurses with overweight (obesity) nutritional status are at a risk of having disorder 1.97 times, the shift nurses with sleep duration < 6 hours are at risk of having disorder 3.78 times and shift nurses with intermediate stress level at risk of having disorder 2.08 times with enhancement blood pressure.Conclusion: There is a relationship between nutritional status, sleep duration and stress level with blood pressure. Sleep duration mostly influences the blood pressure.International Journal of Human and Health Sciences Vol. 04 No. 01 January’20 Page : 55-59

Authors: Mohamad Adam , Yusuf Suhaimi , Mohamad Irfan
Published: November 2019

Paediatric thyroid nodule is a rare occurrence. It occurs about 1.5% in childhood while 4-7% in adulthood. The presentations include anterior neck swelling which moves with deglutition. The treatments of choice are either conservative treatment or complete surgical excision if there is presence of obstructive symptoms or malignancy. We describe an 8-year-old girl presented with left solitary thyroid nodule. Malignancy must be ruled out before conservative management was instituted.International Journal of Human and Health Sciences Vol. 04 No. 01 January’20 Page : 70-72
Structural and electrical properties of dodecylbenzene sulphonicacid doped polypyrrole/zirconium oxide composites
Authors: Irfan M. , Shakoor A.
Published: November 2019

Polypyrrole (PPy) dispersed in an organic solvents were synthesized by means of dodecylbenzenesulphonic acid (DBSA) as useful dopant. Composites of doped PPy with DBSA and also mixed with zirconium oxide (ZrO2) nanoparticles were achieved by chemical polymerization route. Raman spectroscopy has been adopted to confirm the interaction between PPy-DBSA and ZrO2. The SEM also confirms the dual phase structure of platelet and egg shell in PPy-DBSA-ZrO2. Temperature dependant DC conductivity exhibited three dimensional variable ranges hopping (3D-VRH) model. Density of states, hopping length in addition to activation energy were calculated and was observe to be effected by increasing the weight ratio of ZrO2 into PPy-DBSA.
The Feynman-Dyson propagators for neutral particles (locality or non-locality?)
Authors: Dvoeglazov Valeriy V.
Published: November 2019

An analog of the $S=1/2$ Feynman-Dyson propagator is presented in the framework of the $S=1$ Weinberg's theory.The basis for this construction is the concept of the Weinberg field as a system of four field functions differing by parity and by dual transformations.Next, we analyze the recent controversy in the definitions of the Feynman-Dyson propagator for the field operator containing the $S=1/2$ self/anti-self charge conjugate states in the papers by D. Ahluwalia et al. and by W. Rodrigues Jr. et al. The solution of this mathematical controversy is obvious. It is related to the necessary doubling of the Fock Space (as in the Barut and Ziino works), thus extending the corresponding Clifford Algebra. However, the logical interrelations of different mathematical foundations with the physical interpretations are not so obvious. Physics should choose only one correct formalism- it is not clear, why two correct mathematical formalisms (which are based on the same postulates) lead to different physical results?
The relation of Zakharov-Shabat scattering problem to Schrödinger equation with complex potential and approximations for soliton parameters
Authors: Korneev N. , Catana J. A. , Vyslooukh V. A.
Published: November 2019

The relation of Zakharov-Shabat scattering problem to Schr\"{o}dinger equation with complex potential is used to analytically approximate parameters of high power solitons produced in positive Kerr media with chirped parabolic pulses. The soliton parameters are estimated for different types of chirp and intensity distortions. The comparison with numerics is discussed.
Pancreatitis aguda en el embarazo
Authors: Coto Chaves Catalina , Gómez Hernández Cinthya , Riggioni Benavides Valeria
Published: November 2019

La pancreatitis aguda en el embarazo tiene diferentes etiopatogenias, sin embargo su principal causa es la de origen biliar, seguida usualmente por la alcohólica y la hiperlipídica. Los factores de riesgo están asociados a su etiología, aunque la multiparidad y edad materna avanzada están vinculadas. Todas las pacientes presentan dolor agudo persistente en abdomen superior. Este puede irradiar a espalda, aliviar con flexión de torso y puede estar acompañado de fiebre y vómitos. Para diagnosticarla se usan los criterios de Atlanta y se requieren dos criterios positivos para confirmar la pancreatitis. Entre los estudios radiológicos, el Ultrasonido es utilizado  principalmente para causa litiásica, otros empleados son la Tomografía axial computarizada y la Resonancia magnética. Estos además de ser diagnósticos, utilizan los criterios de Ranson, Apache y Balthazar para evaluar la severidad. Se suele tratar mediante fluidoterapia, adecuada nutrición y analgesia, algunos casos requieren antibioticoterapia o incluso cirugía para poder resolver. De no tratarse a tiempo puede generar mortalidad materno-fetal.

Análise do comportamento para além do rótulo de ciência natural
Authors: Azoubel Marcos Spector
Published: November 2019

A análise do comportamento é comumente rotulada como uma ciência natural, mas poucas vezes as justificativas para esta vinculação são apresentadas. Com objetivo de discutir critérios e implicações da atribuição deste rótulo à análise do comportamento, foram analisados textos de analistas do comportamento que defenderam esta classificação. Identificou-se que os critérios não eram suficientemente claros para justificar esta rotulação, em detrimento de outras, e que eram ignoradas suas possíveis implicações indesejáveis. Por fim, o entendimento da análise do comportamento para além do rótulo de ciência natural pode ajudar a desfazer incompreensões, a evidenciar a diversidade das investigações analítico-comportamentais e a propiciar seu diálogo com outras disciplinas.

Published: November 2019

Diferentes instrumentos têm sido desenvolvidos para avaliar os comportamentos de adesão ao tratamento. A observação é o principal procedimento empregado pelo analista do comportamento, cujo desafio é encontrar condições para conduzir observações em saúde. Este estudo teve por objetivo analisar os instrumentos utilizados por analistas do comportamento para avaliar comportamentos de adesão ao tratamento em saúde. Foi realizada uma revisão sistemática de artigos publicados no JABA que testaram intervenções para aumentar a adesão ao tratamento. Foram selecionados e lidos na íntegra 26 artigos. A observação foi o procedimento mais utilizado para avaliar a adesão, seguido de medidas biológicas e de medidores eletrônicos. As pesquisas revistas não avaliaram antecedentes e consequentes das respostas de interesse. Recomenda-se que o procedimento de observação seja empregado de forma tal que possibilite a identificação e a avaliação de variáveis que permitam uma análise funcional dos comportamentos de interesse, possibilitando sua real compreensão, previsão e controle.
