On the dimension of vertex labeling of $k$-uniform dcsl of $k$-uniform caterpillar
Authors: Nageswara Rao K. , Germina K.A. , Shaini P.
Published: July 2016

A distance compatible set labeling (dcsl) of a connected graph $G$ is an injective set assignment $f : V(G) \rightarrow 2^{X},$ $X$ being a nonempty ground set, such that the corresponding induced function $f^{\oplus} :E(G) \rightarrow 2^{X}\setminus \{\emptyset\}$ given by $f^{\oplus}(uv)= f(u)\oplus f(v)$ satisfies $\mid f^{\oplus}(uv) \mid = k_{(u,v)}^{f}d_{G}(u,v) $ for every pair of distinct vertices $u, v \in V(G),$ where $d_{G}(u,v)$ denotes the path distance between $u$ and $v$ and $k_{(u,v)}^{f}$ is a constant, not necessarily an integer. A dcsl $f$ of $G$ is $k$-uniform if all the constant of proportionality with respect to $f$ are equal to $k,$ and if $G$ admits such a dcsl then $G$ is called a $k$-uniform dcsl graph. The $k$-uniform dcsl index of a graph $G,$ denoted by $\delta_{k}(G)$ is the minimum of the cardinalities of $X,$ as $X$ varies over all $k$-uniform dcsl-sets of $G.$ A linear extension ${\mathbf{L}}$ of a partial order ${\mathbf{P}} = (P, \preceq)$ is a linear order on the elements of $P$, such that $ x \preceq y$ in ${\mathbf{P}}$ implies $ x \preceq y$ in ${\mathbf{L}}$, for all $x, y \in P$. The dimension of a poset ${\mathbf{P}},$ denoted by $dim({\mathbf{P}}),$ is the minimum number of linear extensions on ${\mathbf{P}}$ whose intersection is `$\preceq$'. In this paper we prove that $dim({\mathcal{F}}) \leq \delta_{k}(P^{+k}_n),$ where ${\mathcal{F}}$ is the range of a $k$-uniform dcsl of the $k$-uniform caterpillar, denoted by $P^{+k}_n \ (n\geq 1, k\geq 1)$ on `$n(k+1)$' vertices.

Relaciones entre pensamiento histórico y pensamiento crítico en la enseñanza de las ciencias sociales en estudiantes de educación básica secundaria
Authors: Mejía Botero Liliana , Mejía Mejía Ángela
Published: July 2016

Este artículo presenta el desarrollo de una investigación cuyo objetivo fue comprender
las relaciones entre Pensamiento Histórico y Pensamiento Crítico en el marco de la
Enseñanza de las Ciencias Sociales para la Educación Básica Secundaria. Este proyecto
responde a un estudio comprensivo – cualitativo con un componente comparativo,
porque asume un diseño flexible. El hallazgo principal de este estudio fue establecer
que el Pensamiento Crítico, debe incluir entre sus categorías el Pensamiento Histórico, porque las relaciones que entre ellos se dan, se constituyen en mecanismos para hacer lecturas compresivas del pasado, del presente y del futuro.

Por lo tanto el PC y el PH se convierten en pilares esenciales para la formación democrática, ya que se considera desde esta perspectiva al pasado como una posibilidad que fue (argumentación), al presente como una realidad para auto-reflexionar (metacognición) y al futuro como una amplia gama de posibilidades (solución de problemas) para diversificar.

Pharmacology Review: Maternal Selective Serotonin Reuptake Inhibitor Use and Neurologic Effects on the Neonate
Authors: Bondi Deborah S. , Khan Owais A. , Hageman Joseph
Published: July 2016

The management of depression during pregnancy is complicated by the risks to the mother and the fetus by both the disease state itself as well as the medications used to treat it. Serotonin reuptake inhibitors, which include the selective serotonin reuptake inhibitors (SSRIs), are commonly used medications for the treatment of depression and other mood disorders. SSRIs readily cross the placenta and can affect fetal 5-hydroxytryptamine levels. Research into the effects of SSRIs on neonates has shown conflicting results, likely confounded by the fact that maternal depression itself may also lead to adverse outcomes for the neonate. This review aims to discuss the link between markers of fetal central nervous damage and maternal SSRI use, evaluate the literature reporting various short- and long-term neurologic effects in neonates after maternal use of SSRIs, and develop recommendations for the management of and parental counseling about various adverse neurologic outcomes of SSRI use during pregnancy.
Early Nutrition in Preterm Infants: Effects on Neurodevelopment and Cardiometabolic Health
Authors: Kunz Sarah N. , Bell Katherine , Belfort Mandy Brown
Published: July 2016

Nutrition provided during a NICU hospitalization and after hospital discharge is a major determinant of infant growth. Nutritional practices for preterm infants have evolved in recent decades, with an emphasis on increasing growth, primarily through greater macronutrient provision. Specific interventions, such as providing specialized preterm formula or fortified breast milk, are effective in increasing weight gain and other measures of growth, both in the NICU and after discharge. Further, substantial evidence supports the long-term benefits of several nutritional interventions on neurodevelopmental outcomes. More recently, data are emerging to suggest that despite the neurodevelopmental benefits of nutritional fortification, augmenting weight gain may come at a cost to cardiometabolic health. In this review, we discuss the evidence base supporting nutritional interventions for preterm infants in relation to effects on early growth. In addition, we examine evidence regarding the impact of early growth and nutrition on long-term outcomes, highlighting that promoting faster growth to optimize neurodevelopment may also have adverse cardiometabolic effects.
Asymptomatic Kawasaki Disease in a 3-Month-Old Infant
Authors: Pinches Helene , Dobbins Katherine , Cantrell Sarah , May Joseph , Lopreiato Joseph
Published: July 2016

Kawasaki disease (KD) is the leading cause of acquired heart disease in children in the United States. It is a systemic vasculitis characterized by diffuse inflammation of medium and small blood vessels. If untreated it can lead to myocardial infarction, ischemic heart disease, or sudden death. Early recognition and treatment decrease the incidence of coronary consequences, resulting in improved clinical outcomes. Incomplete KD is much less likely to fulfill major clinical diagnostic criteria. Infants <12 months of age are more likely to have an incomplete presentation, and children <6 months of age are more likely to develop cardiac complications. We present a case of a 3-month-old, previously healthy white boy who was noted to have a new transient cardiac murmur during a routine health assessment. He was completely asymptomatic, and physical examination was otherwise within normal limits. An echocardiogram was performed and showed abnormal dilation of several coronary arteries, consistent with the coronary ectasia associated with KD. Laboratory evaluation was significant for values suggestive of systemic inflammation. Based on these results, a presumed diagnosis of incomplete KD was made and treatment administered. Close surveillance was undertaken, and serial laboratory studies and imaging showed gradual resolution of inflammatory markers and cardiac ectasia. This unique case of incomplete KD without any of the physical signs normally associated with the disease emphasizes the spectrum of presentation and the possibility of missing a diagnosis of incomplete disease, reinforcing the need to remain vigilant.

Scaffold degradation during bone tissue reconstruction in Macaca nemestrina mandible
Authors: Bachtiar Endang W. , Amir Lisa Rinanda , Suhardi Pradono , Abas Basril
Published: July 2016

Objective

To examine the degradation of three scaffolds composed of hydroxyapatite/tricalcium phosphate (HA/TCP) with 70∶30 ratio, HA/TCP with 50∶50 ratio, and HA/TCP/chitosan scaffold as analyzed by the RNA expression of matrix metalloprotease 2 (MMP2), interleukin 13 (IL13), and tartrate-resistant acid phosphatase (TRAP) genes.

Methods

The three tested scaffolds and dental pulp stromal cells (DPSCs) were transplanted into the mandibular bone defect of six young male Macaca nemestrina. Defect on the left mandible served as the experimental group and the right mandible served as control group (split mouth design). The biopsies were retrieved at 0, 2, and 4 weeks after cell-scaffold transplantation. The expression of MMP2, IL13, and TRAP was analyzed by real-time PCR (RT-PCR).

Results

The inflammatory cells were still detected in areas where active bone and blood vessel formation occurred. The remnants of scaffold biomaterials were rarely seen. The expression of MMP2, IL13, and TRAP was observed in all samples. Their expressions were increased at week 4 and the decrease of TRAP gene expression in the experimental group was found higher than the control group. TRAP gene in the HA/TCP/chitosan group was found to be the highest at week 2 and lowest at week 4.

Conclusions

Degradation of the scaffold did not induce higher inflammatory response compared to the control yet it induced more osteoclast activity.
Anxiety, Gambling Activity, and Neurocognition: A Dimensional Approach to a Non-Treatment-Seeking Sample
Authors: Medeiros Gustavo C. , Sampaio Daniela G. , Leppink Eric W. , Chamberlain Samuel R. , Grant Jon E.
Published: July 2016

Background and aims

Previous analyses have highlighted significant associations between gambling disorder (GD)/subsyndromal GD and increased rates of anxiety symptoms and anxiety disorders relative to the general population. However, less is known about how anxiety symptoms influence the clinical presentation of gambling problems. The objective of this study was to evaluate the association between anxiety symptoms, gambling activity, and neurocognition across the spectrum of gambling behavior.

Methods

The sample consisted of 143 non-treatment-seeking young adults (aged 18–29 years), in which 63 individuals (44.1%) were classified as recreational gamblers, 47 (32.9%) as having subsyndromal GD, and 33 (23.1%) met criteria for GD.

Results

The main findings were: (a) there was a positive correlation between anxiety severity and gambling severity measured by the number of DSM-5 GD criteria met; (b) there was a positive correlation between anxiety severity and attentional impulsiveness; (c) subjects with suicidality presented higher levels of anxiety; and (d) the severity of anxiety symptoms was negatively correlated with the quality of life.

Discussion and conclusions

This study suggests that anxiety may be associated with relevant clinical variables in the broad spectrum of gambling activity. Therefore, proper management of anxiety symptoms might improve the clinical presentation of gamblers in different areas.

Målet med artikeln har varit att svara på de frågeställningar som formulerades inledningsvis. Gällande vilken funktion de intertextuella referenserna har i den kritiska texten är svaret att det är högst varierande. Den historiskt-genetiska intertexten har som namnet anger en i första hand förklarande funktion, det vill säga att hävda något slags kausalitet. Därtill kommer de rent illustrativa intertexterna, vilka har visat sig kunna användas i en rad olika syften: för att jämföra, för att beskriva, för att värdera, för att kategorisera samt för att kontextualisera. Sammantaget har alltså sex huvudsakliga användningsområdenkunnat urskiljas. Gällande artikelns tredje frågeställning kan konstateras att det recensionsmaterialet i allra högsta grad gör att finna stöd för de intertextuella relationer som enligt Riffaterre karakteriserar den litteraturkritiska diskursen.
How Music Can Influence the Body: Perspectives From Current Research
Authors: Clark Imogen Nicola , Tamplin Jeanette
Published: July 2016

Music is widely used by people of all ages as a stimulant and relaxant to manage everyday situations. Whether to motivate us for exercise or to help us unwind after a busy day, we seem to have an intuitive understanding about the influences music has on our bodies. The body’s responses to music are both conscious and unconscious, involving entrainment with rhythm, hormonal and neurological reactions, and changes in mood, emotion, and pain perception. This article explains these physiological responses to music and provides guidelines for consideration when selecting music to evoke desired bodily responses. Applications using music in rehabilitation are also provided to illustrate health-promoting qualities of music.
How Can Music Build Community? Insight from Theories and Practice of Community Music Therapy
Authors: Steele Megan Ellen
Published: July 2016

Community music therapy has emerged as a widespread approach to music therapy practice since the beginning of the twenty-first century. This article outlines its development from an initial reaction against the individualistic consensus model of traditional music therapy practice, towards its current application across diverse, international contexts. Landmark publications and key terminology will be introduced, and the acronym PREPARE (participatory, resource-oriented, ecological, performative, activist, reflective, and ethics driven) (Stige & Aarø, 2011) used as a means of outlining key qualities of community music therapy. The nature of community music therapy as a context-driven and ethical practice that builds on individual and community resources through collaborative musicking will be illustrated through examples from the literature. The emerging influence of matrix theory as a model for processes within community music therapy (Wood, 2016) and future implications for music therapists as they explore work that shifts between individual and social formats and aims are discussed.
Psychodynamic Music Therapy
Authors: Kim Jinah
Published: July 2016

This paper introduces and explores the basic principles of psychodynamic approaches in music therapy. Music is used as a means to explore both conscious and unconscious issues as well as the internal world of the individuals involved in music therapy. However, the focus of therapy is on therapeutic relationship, especially the dynamics of transference and counter-transference between the client and the music therapist. Musical experiences, such as music listening, songs, and improvisation, can be used to facilitate the therapeutic processes, and to achieve individualized therapeutic goals. When clinically appropriate, verbal processing might play as crucial a role as the musical processing. Practitioners of psychodynamic approaches often strive to gain meaning and in-depth understandings from therapeutic experiences, and the approach is therefore suitable for individuals who are ready to work through their personal issues within a therapeutic relationship. Various approaches and techniques have been developed in psychotherapy as well as in music therapy. Perhaps the only commonality in these approaches is that psychodynamic thinking informs the direction of the therapy and therapeutic processes. Clinical vignettes will be introduced within the article to highlight a triadic dynamic—the client, the music therapist, and the music—in order to illustrate the core aspects of psychodynamic music therapy.

Effects of nanomaterials on hardening of cement–silica fume–fly ash-based ultra-high-strength concrete
Authors: Wang Dehui , Shi Caijun , Wu Zemei , Wu Linmei , Xiang Shuncheng , Pan Xiaoying
Published: July 2016

In this paper, the flowability, compressive strength, hydration heat, porosity and calcium hydroxide content of cement–silica fume–fly ash-based ultra-high-strength concrete (UHSC) incorporating either nano-silica (SiO2) or nano-calcium carbonate (CaCO3) were investigated. Test results showed that the flowability of UHSC was reduced by incorporating nano-silica and nano-calcium carbonate. After incorporating nano-silica, the hydration heat flow of UHSC increased, and the hydration heat of UHSC increased at first but decreased later. For UHSC with nano-calcium carbonate, the hydration heat flow increased and the hydration heat decreased. With the increase of both nano-silica and nano-calcium carbonate content, the compressive strength of UHSC increased at first and then decreased. The porosity decreased at first and increased later with the increase of nano-silica and nano-calcium carbonate content. As regards the calcium hydroxide content, this decreased with the increase of nano-silica content, but increased with the increase of nano-calcium carbonate content.
Creencias de los futuros maestros acerca de la docencia de las matemáticas
Authors: Boqué Torremorell Maria Carmen , Alguacil de Nicolás Montserrat , Pañellas Valls Maria Mercedes
Published: July 2016

A partir de los años ochenta del pasado siglo se empieza a dar importancia a la valoración de la dimensión afectiva en el aprendizaje y aparecen, desde entonces, multiplicidad de estudios para descubrir cuáles son estos factores emocionales y cómo influyen en el aprendizaje, hasta el punto de considerar la educación emocional como un estilo educativo docente que debe transmitir modelos emocionales adecuados. En cuanto a las matemáticas, a menudo provocan, en algunos estudiantes de los grados en educación, un cierto rechazo que hace que se sientan incapaces de afrontar con éxito tareas matemáticas. Es un círculo vicioso, las dificultades crean emociones y actitudes negativas hacia las matemáticas y estos factores afectivos generan rendimientos académicos insatisfactorios. Sin embargo, si la concepción de los maestros sobre las matemáticas es positiva, comunicarán actitudes positivas que favorecerán el proceso de aprendizaje del alumnado. En este sentido, nos interesa conocer las actitudes, creencias y emociones de estudiantes del grado en Educación Primaria respecto a las matemáticas, con el objetivo de mejorar el rendimiento en su futura práctica profesional. En concreto, centramos la atención en conocer los elementos que los estudiantes consideran como determinantes en la tarea docente y la seguridad que muestran para enseñar matemáticas. De los resultados, destacamos la preocupación en las propias posibilidades para fomentar el interés de los niños para resolver problemas matemáticos desarrollando actitudes positivas, y como elemento esencial a tener en cuenta para su profesión, que el maestro de matemáticas debe ser un buen enseñante, bien formado y con diversidad de conocimientos, recursos y registros.
“Yes … I can”: psychological resilience and self-efficacy in adolescents
Authors: Sagone Elisabetta , De Caroli Maria Elvira
Published: July 2016

The aim of this study was to verify the correlations between three types of self-efficacy and factors of resilience in a sample of 155 Italian early adolescents. We used the following measures: the Scholastic Self-efficacy Scale, the Empathic Self-efficacy Scale, and the Problem solving Self-efficacy Scale (Caprara, 2001) and the Resiliency Attitudes and Skills Profile (De Caroli & Sagone, 2014). Results demonstrated that early adolescents highly self-efficient in problem solving and in scholastic performances, and those who reported a higher empathic self-efficacy tended to express a greater resilience than lowly self-efficient ones. Future research could deepen these significant relations in children and adults.

Business Management Simulations – a detailed industry analysis as well as recommendations for the future
Authors: Batko Michael
Published: July 2016

Being exposed to serious games showed that some simulations widely vary in quality and learning outcome. In order to get to the bottom of best practices a detailed review of business management simulation literature was conducted. Additionally, an industry analysis was performed, by interviewing 17 simulation companies, testing a range of full and demo games, and conducting secondary research. The findings from both research efforts were then collated and cross-referenced against each other in order to determine three things: firstly, the practices and features used by simulation companies that have not yet been the subject of academic research; secondly, the most effective features, elements and inclusions within simulations that best assist in the achievement of learning outcomes and enhancement the user experience; and finally, ‘best practices’ in teaching a business management course in a university or company with the assistance of a simulation. Identified gaps in the current research were found to include the effectiveness of avatars, transparent pricing and the benefits of competing the simulation against other teams as opposed to the computer. In relation to the second and third objectives of the research, the findings were used to compile a business plan, with detailed recommendations for companies looking to develop a new simulation, and for instructors implementing and coordinating the use of a simulation in a business management context.

How many nations are we able to imagine?
Authors: Laranjeiro Catarina
Published: July 2016

Who sings the Nation-State in Guinea-Bissau? I will try to answer this and other questions by putting two films into dialogue. The first one is En Nations Födelse (The Birth of a Nation), a film shot by Lennart Malmer and Ingela Romare in Guinea-Bissau in 1973. The second one is a reel sequence, a film fragment that documents the 10th World Festival of Youth and Students which took place in East Berlin in 1973 and where several nations that still did not exist on a political level sought to assert themselves on a symbolical level. The sequence was filmed by Guinean director Sana N’Hada. If the first one was made by two foreigners who were engaged in the liberation struggle in Guinea-Bissau, the second one was shot by a Guinean director who was in East Germany in order to represent his country, then on its way to becoming an independent state. Both films seek to activate mechanisms for the construction of Guinea-Bissau as a nation-state, sharing ideological repercussions. I do not take them as images of the past, but rather as a projected future in an idealized past. A future conjugated in the imperfect, a future imperfective.

A adubação tem proporcionado grandes avanços na produtividade e qualidade de pastagens, e entre os nutrientes, o nitrogênio (N) merece destaque por sua grande extração e aumento da produtividade das pastagens, porém, após sua aplicação ao solo, sofre influência do meio e pode ser perdido, quando mal manejado. Para minimizar tal problema, uma alternativa promissora é o uso de fertilizantes de eficiência aumentada, buscando-se reduzir tais perdas e proporcionar aumento de produtividade. Dessa forma, avaliou-se o efeito de fontes e doses de N na implantação de Urochloa brizantha cv. Xaraés (capim-xaraés) na produtividade e nos valores bromatológicos, em cultivo em condições do Cerrado. O experimento foi conduzido em área experimental no município de Rio Verde - GO, distribuídos em blocos ao acaso com quatro repetições, em esquema fatorial de 3x4. O primeiro fator foram três fontes de N (ureia convencional, ureia de eficiência aumentada e nitrato de amônio); o segundo fator foram quatro doses de N (0, 20, 40 e 80 kg N ha-1 corte-1). O uso da ureia convencional fez-se como a melhor alternativa para a cultura do capim-xaraés (P ≥ 0,05). A dose de nitrogênio recomendada é de 80 kg ha-1 por corte (P < 0,05), em vista do aumento da produtividade de massa seca, e à melhoria da qualidade bromatológica do capim-xaraés.

O trabalho teve como objetivos realizar a análise florística das estruturas horizontal e vertical em um fragmento de Floresta Estacional Decidual (FED) na região do Alto Uruguai, em Frederico Westphalen, RS, Brasil. Foi realizado um censo em uma área amostral de 10.000 m², subdividida em 100 subparcelas de 10x10 m. Realizou-se a mensuração e a identificação de todos os indivíduos de espécies arbóreas com circunferência a altura do peito (CAP)≥ 31,4cm. Com os dados obtidos, foram realizados cálculos de densidade (D), frequência (F), dominância (Do), índice de valor de importância (IVI), índice de valor de cobertura (IVC) e a estratificação dos indivíduos. O maior número de espécies concentrou-se na família Fabaceae (10) e o maior número de indivíduos na família Meliaceae (147 ou 25,3%). Trichilia claussenii C. DC. Nectandra megapotamica (Spreng.) Mez, Achatocarpus praecox Griseb. e Eugenia rostrifolia D. Legrand representaram 38,28% da densidade relativa e Holocalyx balansae Micheli, Trichilia claussenii, Nectandra megapotamica, Cordia americana (L.) Gottshling & J.E.Mill., Phytolacca dioica L., Achatocarpus praecox, e Eugenia rostrifolia representaram 50,5% da dominância relativa. Considerando a estrutura vertical, as sete espécies mais frequentes apresentaram uma maior quantidade de indivíduos no estrato médio. Conclui-se que a área florestal encontra-se em estágio intermediário de sucessão.

La investigación se realizó en las cuencas Ramis y Huancané que forman parte de la región hidrográfica del Titicaca (lado peruano), teniendo como objetivo desarrollar modelos regionales de caudales medios anuales y de persistencia, aplicado a la problemática de la estimación de caudales en zonas sin información hidrométrica para el conocimiento del volumen anual que dispone las cuencas en estudio. La metodología consistió en determinar modelos regionales a través de las ecuaciones de regresión múltiple potencial para la estimación de caudales medios anuales y al 75% de persistencia, siendo las variables explicativas el área de la cuenca (Km2) y la longitud del río principal (Km). Los indicadores de evaluación estadística muestran valores de la raíz del error cuadrático medio (RMSE) entre 2.40 m3/s a 3.62 m3/s, y la eficiencia de Nash-Sutcliffe (NSE) muestra valores entre 97.26% a 97.71%. Los modelos regionales propuestos muestran un buen desempeño y estiman los caudales observados.

 

 

 

ABSTRACT

 The research was conducted in the Ramis and Huancané basins that are part of the hydrographic region of Titicaca (peruvian side), aiming to develop regional models of annual average flows and persistence, applied to the problem of estimating flow in areas without hydrometric information for understanding the annual volume has studied basins. The methodology was to determine regional patterns through the equations of potential multiple regression to estimate annual average flows and 75% persistence, with the explanatory variables the basin area (km2) and the length of river (Km). Statistical evaluation indicators show values of the root mean square error (RMSE) between 2.40 m3/s to 3.62 m3/s, and the Nash-Sutcliffe efficiency (NSE) shows values between 97.26% to 97.71%. The proposed regional models show a good performance and estimate the observed flows.

Accounting Characteristics Of Corporations By Bonds Issuing Methods: Focused On Public Corporations In South Korea
Authors: Hong Soonwook
Published: July 2016

Public corporations of Korea may opt for either online auction or offline issue of bonds, the latter being a more traditional method using investment banks. These two methods have distinct advantages and disadvantages. Corporations that adopt the online issue method tend to have lower earnings management, use more conservative accounting, and enjoy superior scores on the government's assessment of management performance. This means that corporations that choose online, the more transparent issuance method, are more transparent in their accounting practices.
A Case Study Of Share Repurchases: Value Creation Or Financial Engineering
Authors: Wright Susan L.
Published: July 2016

As growth rates in the global economy have slowed, the use of financial engineering as a tool for managing earnings per share (EPS) has grown. Stock repurchasing is frequently used to increase earnings per share and perceived value. Leverage recapitalizations fund major repurchasing programs as firms take advantage of historically low interest rates. This case requires students to analyze the impact of repurchases on EPS and to also reflect on future growth prospects when payout amounts exceed net income over an extended period of time. It allows students to critically examine the inputs for valuing stocks using the total payout model.  The case is constructed using real world information extracted from 10K reports and from recent company announcements. It can be used at the undergraduate (400) or graduate level. It is most suitable for Corporate Financial Management or Corporate Finance courses. The basics of financial statement analysis, time value of money, stock valuation, capital structure and payout practices are necessary to successfully navigate the case.
The Impact of Inventory Valuation Methods on Corporate Financial Reports.
Authors: Caster A. Bruce , Causseaux Wanda K.
Published: July 2016

Business students are generally introduced to LIFO and FIFO in their first accounting course. However, that introduction generally focuses exclusively on computing ending inventory and cost of goods sold.  Students are rarely challenged to compute or analyze the impacts of LIFO and FIFO on the income statement, balance sheet, or cash flow statement.  This paper presents a hypothetical case designed to provide a framework within which students can compute, analyze, and discuss the financial statement impacts and economic impacts of choosing one or the other of these accounting methods.  The questions in this case also address the effects of this choice on financial indicators like liquidity ratios, the impacts of each method on quality of earnings, and the potential impacts of IFRS convergence on companies that are currently using LIFO.One important feature of this case is its adaptability to support a variety of learning outcomes in different courses.  This flexibility results from making the questions posed in the case as independent of each other as possible.  That independence allows a professor to select only the questions that support the learning outcomes for that professor’s specific course.  The teaching notes discuss in detail possible course applications and uses of this case.
Student Usage And Perceptions Of The Value Of Recorded Lectures In A Traditional Face-To-Face (F2F) Class

Published: July 2016

More than ever before, today’s colleges and universities are employing innovative and mutually-beneficial ways to meet the needs of students.  Due to increasing competition and changing demographics, institutions benefit from attracting more students as higher enrollments generate greater revenue; these additional tuition and fees are crucial as costs continue to rise and state funding declines.  Alternative course delivery modalities provide flexibility that can enable more students to obtain access to a postsecondary education as well as appeal to those with different learning styles or who are looking for a less traditional college experience.  In recent years, online programs have grown significantly when compared to the traditional face-to-face (F2F) environment.  While both deliveries have their own advantages and thus supporters, each has its own disadvantages as well.  As a result, blended or hybrid classes, which include features of both F2F and distance courses, are becoming more common.  This article describes a study in which two sections of an F2F tax course offered students access to recorded lectures, and reports the results of a survey designed to ascertain student usage and perceptions of the value of this supplemental material.
