Budgeting in an Era of Political and Institutional Turmoil
Authors: Kinders Mark Allan , Glenn Peggy , Wilson Gregory M.
Published: July 2020

Higher education has existed in a maelstrom for more than two decades of contentious debates on its costs, outcomes, and value. Critics abound among elected officials and decision-makers. Likewise, there is a drumbeat of criticism from within the academy that orbits around mission drift, leadership failures, and questionable practices in pursuit of new revenue. This political and policy dilemma will remain unresolved over the next decade. Such questions of efficiency and effectiveness ultimately impact college budgetary decisions and pose a threat to financial viability. For each criticism or suggested solution there is quite likely to be an opposing opinion that could be grounded in biases or self-interest. Therefore, institutional leaders must be holistic thinkers whose optimal solutions to budgetary challenges must embrace the best practices that cover the full spectrum of providing equal access to a quality education, discovering new knowledge, and serving as stewards of place within their service areas.
Examining the Effects of Blogger Type (Influencers vs. Celebrities) and Post Format in Instagram Marketing
Authors: Ozgen Pelin , Mahmoudian Amir Behrad
Published: July 2020

In the era where credibility of advertisements is decreasing and people are spending more time in social media compared to traditional channels, it is no surprise that marketing professionals employ social media as a new channel for communication. In this new media for communication, the conventional advertising techniques are also coupled with alternating methods such as product placements. In the light of these relatively new applications, the purpose of this study is to examine the effectiveness of marketing communications in social media under different message sources (celebrities vs. influencers) and with different message presentations. In order to serve that purpose, a 2X2 between subjects experiment is modelled with 399 respondents. The results show that a product is better advertised by an influencer rather than a celebrity and type of the blog post had no significant impact on the purchase intention.

Pedagogy in a Potentially Hostile Online Environment
Authors: Williams Lynne , Fudge Tamara Phillips
Published: July 2020

Student-on-student bullying in brick and mortar schools is unfortunately commonplace and has been the subject of research for many years. Alongside the growth of online learning, there has been a corresponding growth in cyberbullying, not only in the student-on-student category, but also student-on-teacher. This new form of bullying can be devastating for the target because, unlike the traditional form of bullying where interactions take place face to face, cyberbullying incorporates email, social media, and texts, which allows the aggression to spread rapidly across a potentially vast range of communication outlets, thus magnifying the effect. Given the potential for significant harm to instructors who are at risk of being targeted by an aggrieved or angry student, more research needs to be done concerning student to teacher cyberbullying. This chapter will examine various cases of student to teacher cyberbullying as well as the role that gender plays in online bullying and end with recommendations for prevention or recourse on the part of the targeted instructor.
Online Doctoral Programs
Authors: Scarpena Kathleen
Published: July 2020

This chapter examines the role of online education in removing the barriers that prevent women from entering, and ultimately successfully completing, doctoral programs. Three core questions guide this chapter as it examines this complex problem of practice: Do online doctoral programs mitigate access barriers specifically for women? What are the implications of access-based college choice decisions for women? How can increased access to online doctoral programs shrink the gap for women in fields where they are underrepresented? This chapter also includes solutions and recommendations for practice designed to support online programs in creating expanded access and opportunity for women, particularly those impacted by underrepresentation, in terms of entry into and completion of doctoral programs.
A Safer Place for Women
Authors: Larkin Judith E. , Pines Harvey A.
Published: July 2020

A feature of online study not widely recognized is that apart from its convenience, which eases the burdens of managing family and work demands, the online educational environment offers control over privacy and visibility. To convey how women, in particular, place importance on having control over privacy, this chapter describes studies the authors have conducted to investigate gender differences in reactions to situations where public performance vs. privacy is involved. While recognizing the success of online courses in meeting privacy needs, attention is also drawn to the challenge that online instructors face to prepare students with skills in public presentation important for success beyond the classroom.
Representation in 21st Century Online Higher Education
Authors: Broderick Maggie
Published: July 2020

This chapter examines representation of women and minorities in 21st century higher education with regard to how the online learning culture serves diverse students. Over the past two decades, faculty and student representation by women and minorities has increased, while online learning has also grown exponentially, becoming almost ubiquitous in its reach and scope. Even with differences across institutions (public versus private, size of the university, and populations served), the online learning environment has a seemingly agreed-upon set of rules, standards, and practices. Arguably, online learning has a distinct culture, which can thus be viewed through the lens of Vygotskyian sociocultural theory. While online learning may have some perceived downsides, a potential benefit is that the nature of the technology and the agreed-upon culture of 21st century online learning across institutions may serve to mask and inhibit implicit bias and thus level the playing field for women and minority students and faculty in higher education.
A Critical Review of Barriers to United States Military Spouse Education and Employment
Authors: Lewis Crystal
Published: July 2020

In the United States, there are over one million military spouses. Frequent geographical relocations, the psychological stress and anxiety associated with spousal deployments, and supporting their children as the only parent while their active duty spouse is away leave military spouses disproportionately accountable for all family obligations. Ultimately, these inequities create barriers for military spouses and their employment and educational pursuits. Despite similarities in lifestyle to active duty service members, military spouses are not categorized as an at-risk population and have not been studied in depth. This chapter utilized the source, survey, synthesize method to address the literature gap surrounding the barriers to military spouse education and employment. Findings from the existing literature were synthesized to present the key themes for studies that investigated the military culture, barriers to military spouses' pursuits of higher education, employment, and career advancement and earnings.

Published: July 2020

Detailed data on incoming solar radiation are needed in the design of solar energy systems of any scale: from large PV plants to small off-grid systems. However, in most cases, obtaining data on measurements of solar radiation is connected with difficulties due to financial or technical restrictions. Often, ground-based measurements of solar radiation are either not carried out at all or only the value of the global horizontal intensity of solar radiation is measured. The aim of the present study is to review and to verify some existing empirical models of the global solar radiation and its components for the climatic conditions of Kyrgyzstan as well as to estimate the applicability of Meteonorm database model for the available solar radiation in the territory of Kyrgyzstan. The necessity to select the most suitable models of the solar radiation is called by the lack of similar studies on this direction for the conditions of the country.

Ethics in Accounting and Finance
Authors: Naidoo Vannie
Published: July 2020

Ethics forms the cornerstone of business and commerce today. It is the lifeblood of every institution be it private or public enterprise. Organisations have to develop and implement a properly structured policy on ethics outlaying proper governance within the institution. Accounting and finance services are crucial in managing a company's finances and wealth. In the accounting profession, in order for there to be transparency and trust, ethics is a crucial area that needs to be present. The many scandals and ethical dilemmas faced by countries organisations throughout the world has made us pause and take stock of what is happening in industry and has prompted action in law and governance towards ethics and corporate governance. South Africa too, has had its fair share of scandal that has had its legal fraternity, government, and business sector develop the Kings I, Kings II, Kings III, and Kings IV laws that stipulate corporate governance and ethics. Organisations have to be honest, professional, and transparent in their business practices.
Effect of Corporate Social Responsibility on Pricing of Small Business Loans
Authors: Vieru Markku , Peltoniemi Janne
Published: July 2020

This study analyzes corporate social responsibility (CSR) issues in small business finance in Finland, especially within relationship banking. The study combines credit-file data obtained from a large local Finnish bank with a CSR questionnaire conducted with the bank's business loan managers. The credit-file data contain specific details of CSR characteristics, as well as relationship-, collateral-, firm-, and loan-specific characteristics. CSR, typically considered as a non-financial item, contains value-relevant financial information which affects the loan pricing level. The results show that both overinvestment in CSR and the value created by CSR are valid but connected to different CSR characteristics. Overinvestment is associated with the environment and value creation with diversity and employees. The results contribute to the understanding of the characteristics of CSR in the context of small business bank lending, as well as more generally to important implications for small firms, banks, and management practices.

Academic, Emotional, and Social Growth in the Second Language Classroom
Authors: Floyd Rachel , Castek Jill
Published: July 2020

This study sought to understand the relationships between socioemotional learning (SEL), second language learning, and digital literacies, and specifically addresses multimodal instruction and composition. Twenty-two students in an intermediate high school French classroom were asked to read an authentic francophone novel and take on one character's persona by creating an Instagram post that reflected that character's viewpoint. Students shared their posts with the class, discussed connections to the novel, and reflected on their composition process. Three data sources were iteratively coded using inductive and deductive methods. The Four Resources Model was adapted for this activity and framed the analysis. Students showed evidence of humor and empathy which led to decreased language anxiety and improved socioemotional learning. The use of an authentic text and the integration of commonly used, real-world social media tools encouraged SEL and helped lower language anxiety. Recommendations and implications for instruction are discussed.
The Perfect Storm of Challenging Students
Authors: Ryan Mark Patrick
Published: July 2020

This chapter explores 15 strategies being employed at various public military charter schools across the United States to support the socio-emotional learning and education of the whole learner. These research-based strategies are intended to overcome and vanquish the adverse childhood experiences (identified in a Kaiser health study), various forms of trauma, and typical “at risk” factors so common amongst families who tend to choose public military academies in the hopes these schools will “fix” the many challenges their children face. Through a careful examination of each strategy (including its research basis and benefits and challenges), the author provides a glimpse into a possible formula other public and private schools might consider employing to meet the socio-emotional and educational needs of students impacted by a cacophony of life's challenges.
The Contribution of Tourism to Peacebuilding Processes
Authors: Teixeira Ana Margarida , Lopes Paula Duarte
Published: July 2020

The concern for environmental protection within an increasingly globalised international system has led to the planning of Transfrontier Conservation Areas, among which Peace Parks aim to achieve or maintain peace across borders. Based on the growing importance that tourism practice has for the sustainability of Peace Parks, this chapter reflects on how the tourism activity developed within Peace Parks can contribute to peacebuilding processes. This dynamic is addressed by analysing a case study, focused on the Great Limpopo Transfrontier Park. It shows that tourism has the potential to positively contribute to sustainability, creating better living conditions for the local population and, consequently, promoting the achievement of peace. However, it also shows that tourism may have the opposite effect if national interests dominate, if there is insufficient consultation of local communities' interests or if sensitive border and land-use issues are not overcome.
Post-War Tourism in the Reconciliation Process of New Zealand Vietnam War Veterans
Authors: Dorsey Maria
Published: July 2020

Tourism has the potential to act as a positive force in reconciliation efforts between countries. The basis of tourism in facilitating reconciliation is premised on people coming into contact with one another in non-adversarial settings, which support a higher probability that positive effects can result from this contact. The investigation on post-war tourism and its role in moving the reconciliation process forward has been limited. Since the Vietnam War ended, there has been a growing phenomenon of Vietnam War veterans returning to visit Vietnam. This chapter examines the impact of New Zealand Vietnam veterans' visits to post-war Vietnam on the reconciliation process with the Vietnamese and with self.

Six open-ended questions were asked to 12 tourists, who came to Şırnak, determined by the purposeful sampling method, with a semi-structured interview form. The answers given by the participants were determined by the descriptive analysis method. The research reveals that tourism is critical in eliminating problems between societies, opening social communication channels, reducing prejudices, and making existing attitudes more positive.
Attention Deficit Hyperactivity Disorder (ADHD)
Authors: Patwardhan Girija Shirish
Published: July 2020

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders of the childhood which is characterized by inattention, hyperactivity and impulsivity. Diagnostic and Statistical Manual of Mental Disorders (DSM) and International Classification of Diseases (ICD) have established and revised the guidelines defining the diagnostic criteria for ADHD. This chapter focused on the diagnostic criteria for ADHD given by the ICD and DSM, and also compared the two. Children are mostly very energetic and active and hence it becomes difficult to decide if the level of activity is to be considered normal or should be taken as an indication of an ADHD symptom. Hence even when the symptoms of ADHD are observable, they require a proper assessment to reach to a diagnostic conclusion and hence diagnostic tools for assessing ADHD were also discussed in the chapter. A brief account of the disorders associated with ADHD was mentioned with an emphasis on how these symptoms would affect the academic, emotional and social areas of lives of the children. Different etiological factors including biological factors, brain anatomy, environmental factors, food /diet were discussed along with the pharmacological as well as non-pharmacological management of ADHD. Pharmacological management included brief discussion about stimulant as well as non-stimulant drugs. On the other hand, non-pharmacological treatment included behavioral interventions, neurofeedback, exercise, family therapy, social skill training and parent training.

Authors: Deka Dorothy Bhandari
Published: July 2020

The prevalence of ADHD is estimated at 5–7% worldwide, which makes it one of the most common psychiatric disorders in children and adolescents. Children with Attention deficit hyperactivity disorder can become difficult if the child is not monitored using correct strategies and techniques. Parents play an integral role in shaping a child. Parenting involves biological as well as the legal aspects and other equally if not more important dimensions of care, protection, nurturance, understanding, guidance, mutual interaction, and partnership occurring within the protective environment of a family. Parenting a differently abled child is very demanding and challenging and the role of family and parents in caring for a child is very crucial, especially development, socializing, and protecting the child.
Executive Function Deficits Among ADHD Students in Classroom Learning
Authors: Nagarhalli Ashwini Deshpande
Published: July 2020

Attention deficit hyperactivity disorder (ADHD) is one of the widely prevalent externalizing disorders from the category of neurodevelopmental disorders. With the constant rise in the diagnosis of a number of cases presenting ADHD or ADHD-like symptoms, the need to understand issues as experienced by the student requires the right interventions for effective management. The core challenges in the area of academics and overall presentation lie with the executive function deficits that the child has. Hence, addressing those and working on skills like attention, working memory, response inhibition, goal setting, planning, problem solving, and organization has to be considered as part of the management plan. The current chapter explores evidence-based issues and strategies to be targeted in the classroom set up for students with ADHD. It also highlights some classroom-specific strategies, which can be focused by the teachers and remedial therapists.

Authors: Yap Ching Seng , Ahmad Rizal , Jalaludin Farah Waheeda , Hashim Nurul Afza
Published: July 2020

Ambidexterity or the ability by individuals or firms to simultaneously and synergistically pursue both exploitation and exploration activities has been found to have positive effects on firm performance. However, the ambidexterity literature has been predominated by the studies at the organizational level, and little is known about the antecedents and consequences of ambidexterity at the individual level. This study examines environmental dynamism and social network as the antecedents of managerial ambidexterity, and knowledge brokerage and firm performance as the consequences. This study tests the mediating role of knowledge brokerage on the relationship between managerial ambidexterity and firm performance. Data are collected from 308 senior executives working in technology manufacturing firms in Malaysia using a questionnaire survey. The findings reveal that environmental dynamism and social networks are significantly and positively related to managerial ambidexterity, and knowledge brokerage mediates the relationship between managerial ambidexterity and firm performance.

For the fulfillment of this research, data were gathered from the service sector's employees and consumers. The research has been processed in three stages: The first stage includes the variables identification from the previously published literature and reduced to smaller groups with the help of IBM SPSS software. Second stage explores the preparation of conceptual model. The third stage involves the identification and substantiation of KM support with post-ERP implementation, which has been accomplished through a short brainstorming session with employees and senior manager of power distribution company. This research concludes that there is positive support of KM in post-ERP implementation.
A Comparative Study of Two Evolutionary Computation Approaches for Formation of Production Processes in Reconfigurable Manufacturing Systems
Authors: Hsieh Fu-Shiung
Published: July 2020

Due to the capabilities to effectively deal with changing demands and business environments, reconfigurable manufacturing systems (RMS) emerge as a paradigm for manufacturers to respond to challenges in the real world. This is to effectively form a production process based on resources available in RMS to meet the demand, which is an important issue. In this article, we address the process formation problem and model it based on a multi-agent system architecture. To specify the capabilities of machines and robots in RMS, we adopt Petri nets as the modelling tool and formulate the process formation problem as an integer programming problem. Due to the computational complexity in solving the integer programming problem, particle swarm optimization (PSO) and differential evolution (DE) approaches have been applied to solve the problem. Effectiveness of applying these two evolutionary computation algorithms to solve the process formation problem is compared based on experimental results.
A Statistical Approach to Three-Dimensional Shape Inspection of Micro-Solder Balls
Authors: Kim Jee Hong
Published: July 2020

This article presents an optical technique for the three-dimensional (3D) shape inspection of micro-solder balls used in ball grid array (BGA) packaging, before attaching them to a board or film. This technique uses an optical source comprising spatially arranged light-emitting diodes (LEDs), and the results are derived based on the specular reflection characteristics of the BGA balls. A vision system is designed to acquire the reflected image from the micro-solder balls. For shape inspection, the locations of the LED point-light-source reflections are determined via image processing, and defects in 3D BGA shapes are detected using statistical information of the relative positions of multiple BGA balls captured in the images. Experiments were conducted to validate our proposed method, and the results revealed that it allows for simultaneous inspection of multiple BGA balls placed arbitrarily in a glass dish, without the need for precise ball-position control.
Evaluating Optimal Parameters for Machining Selective Laser Melting Titanium Alloy Using Wire Cut Electrical Discharge Machining
Authors: Polishetty Ashwin , Littlefair Guy
Published: July 2020

Titanium is known for its poor machinability characteristics due to its low thermal conductivity and high chemical reactivity. This article explores the machinability characteristics of selective laser melting (SLM) titanium alloy Ti-6Al-4V using wire cut electrical discharge machining (WEDM). For titanium alloys, exploring non-traditional machining operation such as WEDM is critical for a material failure or success in a design application. The research is to study the effect of parameters such as servo voltage, pulse on/off, and machining speed with respect to wire tension and wire feed rate on machinability. The outputs under consideration for evaluating machinability are metal removal rate (MRR) and surface finish under minimal interruption due to wire snaps. The article concludes by identifying the optimal factors responsible to produce an efficient and accurate cut with a minimum downtime.

Authors: Verma Kamlesh , Ghosh Debashis , Saxena Harsh , Singh Himanshu , Marathe Rajeev , Kumar Avnish
Published: July 2020

Visual tracking requirement is increasing day by day due to the availability of high-performance digital cameras at low prices. Visual tracking becomes a complex problem when cameras suffer with unwanted and unintentional motion, resulting in motion-blurred unstabilized video. The problem in hand becomes more challenging when the target of interest is to be detected automatically in this unstabilized video. This paper presents a comprehensive single intelligent solution for these problems. The proposed algorithm auto-detects the camera motion, filters out the unintentional motion while stabilizing the video keeping intentional motion only using speeded-up robust features (SURF) technique. Motion smear due to unstabilization is also removed, providing sharp stabilized video output with video quality enhancement of up to 20dB. Gabor filter is used innovatively for auto-detection of target of interest in each stabilized frame. Then the target is tracked using SURF method.

Authors: Lu Carol Yirong , Marek Michael W. , Chen Brendan T. , Pai I. Cheng
Published: July 2020

Facebook Live has become an important resource for both marketers and online shoppers. It has provided communication opportunities for businesses and changed the habits of consumers. This study adopted the means-end chain (MEC) model and used the laddering method to conduct one-on-one in-depth interviews with 40 Facebook users who have used Facebook Live demonstrations to make buying decisions. The overall hierarchical structure of MEC allowed linking of product attributes, consumption consequences, and final value perceptions to draw a hierarchical value map (HVM). The research results show that affordable prices and fulfilling daily needs are the most important product attributes that customers consider. The live webcast demonstrations generated purchase intention and consumption. The ultimate values to which the participants in this study attached the highest importance were “perception of joy,” “perception of satisfaction,” and “perception of value.” Recommendations are provided for businesses using live webcasting as part of their e-commerce programs.

Authors: Gupta Yuvika , Shome Samik
Published: July 2020

Advertising patterns are making significant shifts towards social media from their traditional format. Social media has become a norm for the majority of companies due to progressive change in the mindset of consumers. In the current scenario, working women play an important role in the purchase decision of the family. Moreover, some studies revealed that in some cases working women solely make product purchases. According to the Pew Research, women (73%) lead over men (65%) in the use of social media. The purpose of this study is to identify the factors that are influencing the working women purchase behaviour. The paper witnessed that demographic variables such as age and income of working women do play a significant role in online purchase. The key contribution of this paper is to provide the corporate houses an assessment of the extent to which the working women in India are influenced by social media in their online buying behaviour.
The Keyboard Knows About You
Authors: Tsimperidis Ioannis , Arampatzis Avi
Published: July 2020

One of the causes of several problems on the internet, such as financial fraud, cyber-bullying, and seduction of minors, is the complete anonymity that a malicious user can maintain. Most methods that have been proposed to remove this anonymity are either intrusive, or violate privacy, or expensive. This paper proposes the recognition of certain characteristics of an unknown user through keystroke dynamics, which is the way a person is typing. The evaluation of the method consists of three stages: the acquisition of keystroke dynamics data from 118 volunteers during the daily use of their devices, the extraction and selection of keystroke dynamics features based on their information gain, and the testing of user characteristics recognition by training five well-known machine learning models. Experimental results show that it is possible to identify the gender, the age group, the handedness, and the educational level of an unknown user with high accuracy.

This study evaluated the effect of replacing corn silage with spineless cactus, in combination with Tifton 85 hay or sugarcane bagasse, on the carcass measurements and sensory properties of the meat of lambs finished in feedlot. Twenty-one, intact, Santa Inês males, with an initial body weight of 22.86 ± 2.87 kg and an average age of 150 days, were individually confined for 74 days and fed at will three treatments diets: Corn silage (CS); Spineless cactus + Tifton 85 hay (CT) and Spineless cactus + sugarcane bagasse (CB). Lambs fed CT had a wider croup (p < 0.05) compared to animals fed CS. The replacement of corn silage with CT or CB did not influence (p > 0.05) the body length, withers height or chest circumference of the lambs. Values of carcass length and compactness index were similar (p > 0.05) between treatments. There was a high and positive correlation (p < 0.05) between chest width (0.82) and chest circumference (0.81) of animals with cold carcass weight. The odor and taste of sheep meat fed CT or CB was more accepted when compared to the meat of animals fed corn silage. The replacement of corn silage with spineless cactus in combination with Tifton 85 hay or sugarcane bagasse improves the sensory quality of sheep meat, but does not interfere with carcass measurements.

In total, 240 one-day–old Japanese quails (Coturnix Coturnix Japonica) allocated at random to 6 treatments with 4 replicates and 10 birds in each. Treatments used were: 1) Negative control (without any additives or AFB1); 2) Positive control (basal diet + 2.5 ppm AFB1; 2); 3) TA008 (positive control + 108 cfu/ml Bacillus. megaterium TA008); 4) TA049 (positive control + 108 cfu mL-1 Bacillus. subtilis TA049); 5) TA010 (positive control+ 108 cfu mL-1 Brevibacillus brevis TA010) and 6) P (positive control + 2.5 g kg-1 Polysorb® in feed). Hatchability and embryonic mortality were significantly influenced by additives and AFB1 (p < 0.05). Birds fed TA008 improved 12 % hatchability and reduced 10 % embryonic mortality in compared to positive control (p < 0.05). Weight gain and feed conversion ratio did not affected by treatments (p > 0.05). Feed intake was significantly improved in birds feeding by TA008 at 0-21 days (p < 0.05). There were significant differences on relative weights of carcass, gizzard and proventriculus among treatments (p < 0.05). Serum total protein, albumin, cholesterol, glucose, HDL, globulin and uric acid were significantly affected by treatments (p < 0.05). These results showed that the inclusion of bacillus megaterium as potential probiotic into contaminated diets could improve the adverse effects of AFB1 in Japanese quails.

The purpose was to evaluate the effect of replacement of Tifton 85 hay with Guandu hay on the intake, digestibility and ingestive behavior of dairy goats. Five Saanen goats with average milk production of 2.26 ± 0.10 kg d-1, around 123 ± 4 days of lactation were assigned to a 5 x 5 Latin square design. The treatments consisted of five levels of replacement with Guandu: 0, 8.4, 16.8, 25.2, or 36.4 %. We sampled the food offered, leftovers and feces to calculate intake and digestibility, and the ingestive behavior was monitored for 24 hours. Regression analysis was applied with 5% significance. The nutrient intake and the digestibility of dry matter, organic matter and protein decreased linearly with increasing levels of Guandu hay in the diet (p < 0.05). On the other hand, the neutral detergent fiber digestibility increased linearly, without change the water intake and ingestive behavior with replacement levels of Tifton hay with Guandu hay in the diet (p < 0.05). The replacement of up to 36.4% Tifton hay with Guandu hay in the dairy goat diet reduces the intake and digestibility of dry matter, organic matter and protein, and increasesfiber digestibility, without changing the ingestive behavior and water intake.

The aim of this study was to develop an experimentally-induced canine model of left ventricular hypertrophy through banding of the ascending aorta using nylon ties. Seven clinically normal dogs free of cardiovascular disease were used. Nylon tie was used in banding the mid-ascending aorta. Clinical, radiographic and echocardiographic evaluations were done at 1.5, 3 and 6 months. Dogs were euthanized at 6 months for post mortem and histopathological evaluation. Clinically, dogs did not exhibit any signs of cardiovascular disease at 1.5 or 3 months, while at 6 months two dogs (28.6 %) exhibited mild weight loss, exercise intolerance and heart murmurs. Radiographic evaluation revealed significant increase in cardiac size only at 6 months based on measurement of the cardiothoracic area evaluation. Echocardiography revealed increased left ventricular wall thickness starting from 1.5 month, although this increase was statistically significant at 3 and 6 months (p > 0.05). Left ventricular hypertrophy was confirmed by post mortem examination. Histopathological sections of left ventricle in all dogs demonstrated myocyte hypertrophy and interstitial fibrosis. This model simulates the naturally occurring ventricular hypertrophy using a rapid and economic technique. Such models are required to understand pathogenesis of heart disease and to develop effective treatment strategy.

The objective of this work is to evaluate the influence of accelerated aging test at 41ºC on the germination and seed vigor of Piptadenia moniliformis Benth. Two experiments were conducted. Experiment 1: seeds were submitted to dormancy overcoming treatments. They were immersed into sulfuric acid for 0 (intact seeds), 5, 10, 15, 20 and 25 minutes. Experiment 2: two methods were evaluated for the accelerated aging test at 41ºC, that is, the traditional method and the saturated NaCl solution method with exposure periods of 0, 24, 48, 72 and 96 hours. After each treatment, the seeds were subjected to electrical conductivity and germination tests. Seeds overcame their dormancy when immersed into concentrated sulfuric acid for 5, 10, 15, 20 or 25 minutes, but the germination was faster when immersed for 20 minutes. The different methods for the accelerated aging test, decreased the germination potential and seed vigor of P. moniliformis after 24 hours of exposure. Regarding the method used, the saturated solution provided, in general, the best results since the seed water content was lower, thus reducing the proliferation of fungi. The electrical conductivity test showed that, by increasing the aging period regardless of the method, there is an increase in seed deterioration, corroborating with germination results, which showed that the correlation was moderate and negative and indicated that the higher the conductivity, the lower the percentage and the germination speed index. The immersion of seeds of P. moniliformis into concentrated sulfuric acid for 20 minutes provides a fast and increased germination. The methods for accelerated aging at 41ºC, traditional and saturated solution, can be used as vigor tests to evaluate the physiological quality of seeds.
