Impact of different types of polycarboxylate superplasticisers on spontaneous crystallisation of ettringite
Authors: Meier Markus R. , Rinkenburger Alexander , Plank Johann
Published: February 2016

The spontaneous crystallisation of ettringite from combined calcium hydroxide (Ca(OH)2) and aluminium sulfate (Al2(SO4)3) solutions was investigated in the presence and absence of three different kinds of polycarboxylate superplasticisers. The crystallisation period was limited to 10 s only to study the initial crystals, which provide the anchoring sites for most admixtures in cement. It was found that, in the absence of polycarboxylate polymers, only few, but large (l ∼ 3·5 μm), hexagonal, prismatic ettringite crystals exhibiting numerous defects on their surfaces were formed. However, when polycarboxylate polymers were present during the crystallisation, then the crystal sizes decreased to ∼ 0·5–2·1 μm. Generally, crystal sizes were found to decrease with increasing specific anionic charge of the same kind of polycarboxylate polymer. Apparently, polymers exhibiting a higher affinity to the crystal surfaces of ettringite inhibit its growth more strongly and produce smaller crystals. Furthermore, the specific chemistry (base monomers) of the polycarboxylate also has an impact on the size of ettringite crystals.
Water and sediment quality characteristics of medium saline traditional shrimp culture system (bheri)
Authors: Priyadarsani Leesa , Abraham Thangapalam Jawahar
Published: February 2016

Quality of water in shrimp culture ponds depends on several physical, chemical and biological processes. In this study, the physico-chemical characteristics of water and sediment samples from inlet, pond and outlet of a traditional shrimp culture pond, locally called as bheri, were examined for nine months from March to November 2011. Majority of the physicochemical parameters of bheri were well within the optimum levels. The average BOD values in pond water and outlet water were 2.03 ppm and 2.33 ppm, respectively. In pond water, the levels of ammonia were from 0.012 to 0.033 ppm, which was well within the safe level (<0.1 ppm). The present study recorded low levels of nitrite (0.0037 to 0.0043 ppm) and nitrate (0.056 - 0.091 ppm) in pond water, which was within the safe levels recommended for shrimp farming. These physicochemical parameters did not affect the cultured shrimp as there was no incidence of diseases or growth retardation during the culture period. The effluent water characteristics also did not vary much and well within the recommended levels for protecting the coastal ecosystem. It is unlikely that the traditional shrimp culture pose any adverse environmental effect when effluents are discharged into the open coastal ecosystem.
A variação teu/seu: um estudo diacrônico e sincrônico
Authors: Pereira Rachel De Oliveira
Published: February 2016

O presente trabalho orienta-se para o estudo da forma possessiva teu em oposição à forma seu, através de duas perspectivas: na diacronia e na sincronia. Para a análise diacrônica, observa-se a utilização das estratégias possessivas em cartas pessoais de diferentes famílias datadas de 1870 a 1980. No total foram utilizadas 143 cartas para compor o corpus, no entanto, com o intuito de fazer uma análise mais confiável, tais cartas foram divididas em torno de 10 cartas por década. Na análise sincrônica, observou-se a variação entre as formas possessivas através de esquetes do canal “Porta dos Fundos”. Desta maneira, busca-se descrever a utilização dessas formas, observando seus usos de acordo com a situação comunicativa estabelecida, através dos padrões discutidos pela teoria do Poder e Solidariedade (BROWN; GILMAN, 1960). O estudo também leva em conta os pressupostos teóricos da teoria variacionista quantitativa laboviana (LABOV, 1994), visando identificar os fatores linguísticos e extralinguísticos que determinam o uso dos pronomes possessivos referentes à segunda pessoa do singular. Em síntese, este estudo preliminar aponta que as formas possessivas tendem a acompanhar o comportamento do sujeito na diacronia e que o possessivo seu, aparentemente, possui um comportamento polifuncional. 
Retinol-binding protein 4 in obese and obese-diabetic postmenopausal women in Montenegro
Authors: Klisic Aleksandra , Gouri Adel , Skerovic Verica , Jovanovic Milovan , Kavaric Nebojsa
Published: February 2016

Introduction: Menopause is associated with an increase in visceral fat and obesity and is the leading risk factor for insulin resistance (IR) and type 2 diabetes mellitus (T2DM). Recent evidence suggests that retinol-binding protein 4 (RBP4) is not an independent determinant of IR and its role in human glucose metabolism is not well clarified. We examined RBP4 and its association with IR, cardiometabolic and kidney parameters in obese postmenopausal women with and without T2DM.Methods: Basic anthropometric, biochemical parameters, and blood pressure (BP) were determined in 50 obese diabetic and 50 obese non-diabetic sedentary postmenopausal women, and compared with 50 healthy normal weight controls.Results: Higher levels of RBP4 were observed in obese individuals, as compared with normal weight group (p=0.033). However, we did not find significant difference between obese non-diabetic and obese-diabetic individuals (p=0.583). Serum RBP4 did not correlate with anthropometric measurements or any indicator of glucose metabolism in diabetic group, whereas RBP4 correlated with creatinine (r=0.416, p=0.003), eGFR (r= -0.304, p=0.032) and triglycerides (r=0.484, p<0.001). In obese non-diabetic group, correlations were observed with fasting glucose (r=0.346, p=0.014), insulin (r=0.292, p=0.038), HOMA-IR (r=0.329 p=0.020), HbA1c (r=0.326, p=0.021), creatinine (r=0.399, p=0.004), eGFR (r= -0.389, p=0.005), HDL-c (r= -0.316, p=0.025), triglycerides (r=0.461, p<0.001), and systolic BP (r=0.286, p=0.044). In multiple regression analysis, triglycerides (Beta=0.302, p<0.001) and eGFR (Beta= -0.188, p=0.015) were independent predictors of RBP4.Conclusions: Serum RBP4 is not increased in obese type 2 diabetic postmenopausal women, but is associated with triglycerides and eGFR independently of diabetes.
Women’s Studies as Virus: Institutional Feminism, Affect, and the Projection of Danger.
Authors: Fahs Breanne , Karger Michael
Published: February 2016

Because women’s studies radically challenges social hierarchies and lacks a unified identity and canon of thought, it often negotiates a precarious position within the modern corporatized university. At the same time, women’s studies offersâ€”by virtue of its interdisciplinary, critical, and “infectious” structureâ€”cutting-edge perspectives and goals that set it apart from more traditional fields. This paper theorizes that one future pedagogical priority of women’s studies is to train students not only to master a body of knowledge but also to serve as symbolic “viruses” that infect, unsettle, and disrupt traditional and entrenched fields. In this essay, we first posit how the metaphor of the virus in part exemplifies an ideal feminist pedagogy, and we then investigate how both women’s studies and the spread of actual viruses (e.g., Ebola, HIV) produce similar kinds of emotional responses in others. By looking at triviality, mockery, panic, and anger that women’s studies as a field elicits, we conclude by outlining the stakes of framing women’s studies as an infectious, insurrectional, and potentially dangerous, field of study. In doing so, we frame two new priorities for women’s studiesâ€”training male students as viruses and embracing “negative” stereotypes of feminist professorsâ€”as important future directions for the potentially liberatory aspects of the field.
Peace in Colombia is also a women's issue
Authors: Ibarra Melo Maria Eugenia
Published: February 2016

In this article, we show the ambiguous relationship between the Colombian state and civil organizations in an analysis that examines the motives, methods, and form in which women's organizations that have mobilized for peace in Colombia have benefited from the structure of political opportunities during the two-term government terms of democratic security (2002-2010). For this purpose, it was very important to follow the press and the means of information diffusion on the Web by the women's organizations, interviews with leaders, and what accompanied their actions over more than 10 years. The main conclusion drawn from this work is the identification of new methods of leadership that have structured activism around peace and human rights, thus contributing to the emergence of a new political actor and the transformation of the political culture of Colombia.

Raseros para la Segmentación y Precarización del Profesorado Universitario: Márketing y Sexismo
Authors: Carames Rosa , Mullet Tomeu
Published: February 2016

Este artículo pretende demostrar la necesidad de cambio y mejora de los procedimientos de evaluación de la Calidad de la investigación (Tejedor y Jornet, 2008). El estudio de casos y análisis de contenido, de la información aportada por los escritos de respuesta de denegación de sexenios emitidos por la CNEAI (Comisión Nacional para la Evaluación de la Actividad Investigadora) para el PDI (Personal Docente e Investigador) funcionario de carrera de distintas Universidades en España con más de veinte años de experiencia profesional, evidencia la ausencia de fiabilidad interjueces o grado de acuerdo entre las valoraciones realizadas por los expertos implicados en los procesos de valoración que se proponen como aplicación de “criterios objetivos” para dichas evaluaciones. Según García (2015) la estructura de las plantillas envejeció y se feminizó, paralelamente funcionan procesos de “agujero negro” que revitalizan rancias dinámicas sexistas y competitivas de desgaste, que aplican raseros de segmentación y precarización entre el PDI de la Universidad en España, que camuflan raciones por razones, al amparo del metabolizante márketing del Mercado de la Ciencia redefinida para Refundar la Universidad del siglo XXI en un Nuevo Orden Gloncal (Cascante, 2009) denominado Espacio Europeo de Educación Superior tergiversando el Plan Bolognia.
Educación y entorno en la infancia. Ingredientes clave en el desarrollo del pensamiento creativo
Authors: Serrano Cecilia
Published: February 2016

La educación y el entorno vivido en la infancia favorecen o dificultan el desarrollo de un pensamiento creativo. Las diversas experiencias creativas que acontecen en la infancia y el contexto en el que se desarrollan son claves en la elección de una profesión y/o un itinerario formativo en la edad adulta. Este es el caso de diferentes profesionales cuya decisión de escoger un oficio u otro, estuvo marcada durante su periodo educativo. Hemos realizado ocho historias de vida a trabajadores creativos de la región de Aragón (España), considerando como empleos creativos el listado realizado por Florida (2002). Algunas de las conclusiones son la importancia del desarrollo de un pensamiento crítico y creativo en las aulas y su conexión con la familia, amigos, instituciones, etc. El entorno es un aspecto clave para entender el desarrollo creativo de estos profesionales.
Análisis de crecimiento de árboles de guayaba (Psidium guajava L.) var. ICA Palmira II sometidos a deficiencia de N, P, K, Mg, Ca y B en fase de vivero
Authors: Dussán C. Sindy Lorena , Villegas H. Daniel Andrés , Miranda L. Diego
Published: February 2016

La guayaba especie frutícola perteneciente a la familia Myrtaceae; se destaca por ser una fruta de alto contenido vitamínico; es un cultivo con poca investigación y asistencia técnica, especialmente en el área de la fertilización, sin embargo, cuenta con enorme potencial de expansión en cuanto a tecnificación y rentabilidad. Plantas de guayaba var. ICA Palmira II de 3 meses de edad fueron trasplantadas a bolsas plásticas, fueron mantenidas durante 128 días en condiciones de invernadero plástico. Se indujo deficiencia nutricional mediante la técnica del elemento faltante en aplicación de soluciones nutritivas, usando un diseño experimental totalmente aleatorizado con 152 unidades muéstrales, 8 tratamientos y 3 repeticiones, de la siguiente forma: T0: aplicación de agua sin adición de elementos minerales; T1: fertilización completa (testigo absoluto); T2: sin nitrógeno (-N); T3: sin fósforo (-P); T4: sin potasio (-K); T5: sin magnesio (-Mg); T6: sin calcio (–Ca) y T7: sin boro (-B).  Se determinó la tasa relativa de crecimiento (TRC), índice de área foliar (IAF), área foliar especifica (AFE), relación de área foliar (RAF) y tasa de asimilación neta (TAN). Se encontró que en comparación con la fertilización completa la omisión de nitrógeno, fue el tratamiento más limitante en etapas tempranas de desarrollo de plántulas de guayaba. En cambio, en el tratamiento sin boro (–B), el crecimiento y desarrollo de las plantas no se limitó, ya que no se reprimió la emisión de nuevos tejidos y la acumulación de materia seca. La carencia de K, P, Mg y Ca, no presentó efecto negativo sobre el crecimiento y desarrollo de los árboles de guayaba, sin embargo, las plantas sometidas a estos tratamientos presentaron síntomas característicos de la deficiencia en plantas de interés agronómico.

Errores comunes relativos al valor terminal expresado en forma de perpetuidad
Authors: Sabal Cárdenas Jaime
Published: February 2016

Artículo de reflexiónAl valorar una firma los flujos de caja libres después del horizonte de proyección son generalmente representados por un valor terminal.Este trabajo centra su atención en el valor terminal expresado como el valor presente de una perpetuidad. Siete importantes errores han sido identificados cuando se trabaja con dichas perpetuidades. Las principales causas de dichos errores son: a) Desestimar la inestabilidad de los flujos de caja libres durante el horizonte de proyección; b) Inconsistencia entre el último flujo de caja libre del horizonte de proyección y los supuestos sobre reinversión y crecimiento; c) Ignorar la posibilidad de crecimiento a través de financiamiento exógeno; d) Inconsistencia entre la tasa de cambio de mercado y la tasa de equilibrio cuando se trabaja con diferentes monedas; e) Ignorar la posibilidad de varias fases de crecimiento; y f ) Establecerla tasa de crecimiento sin la debida consideración a las características de la firma y de la industria, la inflación, y el crecimiento y cuota de mercado.
Análisis del aporte al desarrollo empresarial regional del clúster automotriz de Nuevo León México
Authors: Montoya Ortega Manuel
Published: February 2016

Artículo de investigaciónLa clusterización fue propuesta en sus inicios como una estrategia para impulsar el desarrollo económico regional, donde los gobiernos locales apoyan a las industrias consideradas como estratégicas para que éstas sean más competitivas y desarrollen sus cadenas de valor. Michael Porter (1990) propuso estas ideas en su trabajo La Ventaja Competitiva de las Naciones, pero no proporcionó evidencia de que así sea. Sin embargo, se encuentran con casos concretos donde las empresas de un sector en una región se han asociado por medio de un clúster, junto con el gobierno y la academia, para desarrollar actividades que les generan beneficios y les ayudan a ser más competitivos.En el presente artículo se revisan los conceptos básicos para entender qué es y cómo funciona una iniciativa clúster y presentamos el caso concreto del Clúster Automotriz de Nuevo León, Claut, donde las empresas han generado ventajas competitivas por medio de la colaboración. Se realizó una investigación entre los directores de las empresas e instituciones que lo conforman, para entender el tipo de beneficio que han obtenido por medio de la colaboración. Se encontró que todos los asociados han obtenido beneficios cuantificables, que varían entre las empresas grandes, las medianas y pequeñas
La Neurociencia como oportunidad estratégica para el Área Comercial

La gestión de la “horizontalidad” tecnológica: el caso Vaelsys
Authors: Merino Carlos , Cermeño Eduardo
Published: February 2016

Artículo de casoEl fenómeno emprendedor presenta diferentes facetas sobre las que se centran los estudios y análisis, a saber, habilidades, motivaciones, tecnología, financiación, riesgo, etc., todas ellas importantes retos para el proceso de consolidación de los proyectos innovadores. Desde este punto de vista las nuevas empresas de base tecnológica caracterizadas por el lema “el I+D como negocio” revisten un claro papel protagonista dentro del interés estratégico que ostenta el colectivo de emprendedores.Así, aspectos clave en esta aproximación empresarial giran alrededor del marco de la gestión que debe acompañar el contexto de know how científico-tecnológico que poseen de forma diferenciada estos proyectos. No obstante, a pesar de esta especialización necesaria para dotar de valor añadido a las nuevas empresas de base tecnológica surgen a veces determinadas realidades organizativas que cuentan con una característica fundamental por oportunidad y por requerimientos de gestión, que en este caso se concreta en la horizontalidad o transversalidad que posee la oferta.De esta forma, su aplicación se posibilita a múltiples sectores, mercados, segmentos o realidades, cuyo apropiado tratamiento necesita de la mezcla de visión sistémica y particular de cada uno de los cuadrantes en los que ubicar el producto/servicio.Este es el caso de la empresa Vaelsys, enmarcada en el contexto tecnológico de la videovigilancia cuyo amplio espectro de aplicaciones evidencia una importante capa de estrategia y gestión para adecuar la oferta en cada caso de aplicación, contenido clave de valor añadido para la transferencia de conocimiento a otros emprendedores a modo de caso de estudio
Costo promedio ponderado de capital (CPPC) y deuda con riesgo: una presentación sencilla

Artículo de reflexiónEl costo de la deuda rara vez se puede considerar libre de riesgo. Sin embargo, en aras de la simplicidad, en la mayoría de las discusiones sobre el costo promedio de capital (CPPC) se supone que la deuda es libre de riesgo. Como resultado, cuando se calcula el CPPC se utiliza un costo de la deuda, d, mayor que la tasa libre de riesgo, rf .En este trabajo, usando un modelo binomial sencillo, se examina el costo promedio ponderado de capital (CPPC) con deuda bajo y sin impuestos. Los impuestos plantean complicaciones adicionales, lo cual supera el propósito del trabajo. Con deuda bajo riesgo se debe usar la tasa esperada de rentabilidad de la deuda, en lugar de la tasa pactada o contractual para incluirla en el CPPC. Más aun, se modela el costo esperado de la deuda como una función creciente del monto de la deudaClasificación JEL: D61: Análisis Costo-Beneficio; G31: Presupuestación de capital; H43: Evaluación de proyectos
Responsabilidad social empresarial como expresión de avance del conocimiento del hombre desde la cultura organizacional

Published: February 2016

Artículo de reflexiónSon claras las razones de la implementación de la responsabilidad social en las organizaciones, soportadas en los argumentos expuestos por las diferentes teorías -que estudian el fenómeno, las teorías instrumental, política, integradora y ética- El documento tiene como objetivo explicar la implementación de la responsabilidad social empresarial desde la cultura organizacional, como una expresión del avance del conocimiento del hombre. Esto se sustenta en el carácter voluntario de su aplicación y su relación de complementariedad con el sistema capitalista imperante.Se analizan los elementos de la cultura organizacional en especial, desde la perspectiva de la escuela ecológica adaptacionista, y la teoría de sistemas. Se explica la necesidad de incorporar las prácticas de responsabilidad social, dado que la cultura de las organizaciones es un reflejo de la cultura en la sociedad, por encontrarse la empresa en un constante diálogo con el entorno en el que se mueve. Por su parte, la teoría de sistemas, que propone la organización como un sistema abierto y vivo, ofrece los argumentos necesarios para reforzar este planteamiento.

Alignment of Citation Behaviors of Philosophy Graduate Students and Faculty
Authors: Knievel Jennifer
Published: February 2016

Objective – This study analyzes sources cited by graduate students in philosophy at the University of Colorado Boulder (UCB) in 55 PhD dissertations and master’s theses submitted between 2005 and 2010, to discover their language, age, format, discipline, whether or not they were held by the library, and how they were acquired. Results were compared to data previously collected about sources cited by philosophy faculty at UCB, in books published between 2004 and 2009, to identify how closely citation behaviors aligned between the two groups.

Methods – Citations were counted in the PhD dissertations and master’s theses. Citations to monographs were searched against the local catalog to determine ownership and call number. Comparison numbers for faculty research were collected from a previous study. Results were grouped according to academic rank and analyzed by format, language, age, call number, ownership, and method of purchase.

Results – Graduate students cited mostly books, though fewer than commonly found in other studies. Citations were almost entirely of English language sources. Master’s students cited slightly newer materials than doctoral students, who in turn cited newer materials than faculty. The library owned most cited books, and most of those were purchased on an approval plan. Doctoral students most frequently cited resources outside the discipline of philosophy, in contrast to master’s students and faculty.

Conclusions – The citation behavior of graduate students in philosophy largely, but not entirely, mirrors that of the faculty. Further study of citation behavior in humanities disciplines would be useful. Understanding the behavior of philosophers can help philosophy librarians make informed choices about how to spend library funds.

Far from a Trivial Pursuit: Assessing the Effectiveness of Games in Information Literacy Instruction
Authors: Tewell Eamon C , Angell Katelyn
Published: February 2016

Abstract

Objective – To determine whether playing library-related online games during information literacy instruction sessions improves student performance on questionnaires pertaining to selected research practices: identifying citation types and keyword and synonym development.

Methods – 86 students in seven introductory English composition classes at a large urban university in the northeastern United States served as participants. Each class visited the library for library instruction twice during a given semester. In the experimental group students received information literacy instruction that incorporated two online games, and the control group received the same lesson plan with the exception of a lecture in place of playing games. A six-item pre- and posttest questionnaire was developed and administered at the outset and conclusion of the two-session classes. The 172 individual tests were coded, graded, and analyzed using SPSS.

Results – A paired sample t-test comparing the control and experimental groups determined that that there was a statistically significant difference between scores on pre-tests and post-tests in the experimental group but not the control group.

Conclusion – Students who played the online games improved significantly more from pre-test to post-test than students who received a lecture in lieu of playing online games, suggesting that participating in games related to the instruction they received resulted in an improved ability to select appropriate keywords and ascertain citation formats. These findings contribute to the evidence that online games concerning two frequently challenging research practices can be successfully applied to library instruction sessions to improve student comprehension of such skills.

Our Future, Our Skills: Using Evidence to Drive Practice in Public Libraries
Authors: Hallam Gillian , Ellard Robyn
Published: February 2016

Abstract

Objective – The public library sector’s future prosperity is contingent upon a well-trained, experienced, and valued workforce. In a collaborative initiative, State Library Victoria (SLV) and the Public Libraries Victoria Network (PLVN) commissioned an in-depth research study to examine the skills requirements of staff across the State. The Our Future, Our Skills project sought to identify the range of skills used by public library staff today, to anticipate the range of skills that would be needed in five years’ time, and to present a skills gap analysis to inform future training and development strategies.

Methods – The project encompassed qualitative and quantitative research activities: literature review and environmental scan, stakeholder interviews, focus groups and a workforce skills audit. The research populations were staff (Individual survey) and managers (Management survey) employed in 47 library services, including metropolitan, outer metropolitan and regional library services in Victoria.

Results – The high response rate (45%) reflected the relevance of the study, with 1,334 individual and 77 management respondents. The data captured their views related to the value of their skillsets, both now and in five years’ time, and the perceived levels of confidence using their skills. The sector now has a bank of baseline evidence which has contributed to a meaningful analysis of the anticipated skills gaps.

Conclusions – This paper focuses on the critical importance of implementing evidence-based practice in public libraries. In an interactive workshop, managers determined the skills priorities at both the local and sectoral levels to inform staff development programs and recruitment activities. A collaborative SLV/PLVN project workgroup will implement the report’s recommendations with a state-wide workforce development plan rolled out during 2015-17. This plan will include a training matrix designed to bridge the skills gap, with a focus on evaluation strategies to monitor progress towards objectives. The paper provides insights into the different ways in which the project workgroup is using research evidence to drive practice.
Enhancing Access to E-books
Authors: Harker Karen , Sassen Catherine
Published: February 2016

Abstract

Objective – The objective of the study was to determine if summary notes or table of contents notes in catalogue records are associated with the usage of e-books in a large university library.

Methods – A retrospective cohort study, analyzing titles from three major collections of e-books was employed. Titles were categorized based on the inclusion of the MARC 505 note (table of contents) or MARC 520 note (summary) in the catalogue record. The usage was based on standardized reports from 2012-2013. The measures of usage were the number of titles used and the number of sections downloaded. Statistical methods used in the analysis included correlations and odd ratios (ORs). The usage measures were stratified by publication year and subject to adjust for the effects of these factors on usage.

Results – The analysis indicates that these enhancements to the catalogue record increase usage significantly and notably. The probability of an e-book with one of the catalogue record enhancements being used (as indicated by the OR) was over 80% greater than for titles lacking the enhancements, and nearly twice as high for titles with both features. The differences were greatest among the oldest and the most recently published e-books, and those in science and technology. The differences were least among the e-books published between 1998 and 2007 and those in the humanities and social sciences.

Conclusion – Libraries can make their collections more accessible to users by enhancing bibliographic records with summary and table of contents notes, and by advocating for their inclusion in vendor-supplied records.

Abstract

Objective – This study aimed to identify assessment opportunities and stakeholder connections in an emerging technologies department. Such departments are often overlooked by traditional assessment measures because they do not appear to provide direct support for student learning.

Methods – The study consisted of a content analysis of departmental records and of weekly activity journals which were completed by staff in the Emerging Technologies and Services department in a U.S. academic library. The findings were supported by interviews with team members to provide richer data. An evidence based framework was used to identify stakeholder interactions where impactful evidence might be gathered to support decision-making and to communicate value.

Results – The study identified a lack of available assessable evidence with some types of interaction, outreach activity, and responsibilities of staff being under-reported in departmental documentation. A modified logic model was developed to further identify assessment opportunities and reporting processes.

Conclusion – The authors conclude that an evidence based practice research approach offers an engaging and illuminative framework to identify department alignment to strategic initiatives and learning goals. In order to provide a more complete picture of library impact and value, new and robust methods of assessing library technology departments must be developed and employed.
The Impact of Leadership Development on the Organizational Culture of a Canadian Academic Library
Authors: Crawley-Low Jill
Published: February 2016

Objective – To determine the perceived impact of leadership development on the behaviours and competencies of employees and the organizational culture of the University Library, University of Saskatchewan, Canada.

Methods – Using grounded theory methodology, the study was conducted in an academic library serving a mid-sized medical-doctoral university in western Canada. Twenty-one librarians and support staff who had completed the University Library’s Library Leadership Development Program (LLDP) participated in one-on-one interviews of 40-60 minutes duration. Interview transcripts were prepared by the researcher and reviewed by the participants. After editing, those source documents were analyzed to reveal patterns and common threads in the responses. The coding scheme that best fits the data includes the following four headings: skill development, learning opportunities, strategic change management, and shared understanding of organizational vision and values.

Results – According to the responses in interviews given by graduates of the Library Leadership Development Program, the library’s investment in learning has created a cohort of employees who are: self-aware and engaged, committed to learning and able to develop new skills, appreciative of change and accepting of challenges, or accountable and committed to achieving the organization’s vision and values.

Conclusion – Competencies and behaviours developed through exposure to leadership development learning opportunities are changing the nature of the organization’s culture to be more collaborative, flexible, open and accepting of change and challenge, supportive of learning, able to create and use knowledge, and focussed on achieving the organization’s vision and values. These are the characteristics commonly associated with a learning organization.

A Holistic Look at Reference Statistics: Whither Librarians?
Authors: Scales B. Jane , Turner-Rahman Lipi , Hao Feng
Published: February 2016

Abstract

Objective – Washington State University (WSU) Pullman campus librarians track a diverse set of reference statistics to gain a “holistic” look at local reference transaction trends. Our aim was to aggregate virtual, reference desk and office transaction data over the course of three years to determine staffing levels. Specifically, we asked “Where should reference librarians be to answer questions?”

Methods – Using Springshare’s LibAnalytics, we generated longitudinal (2012-2014) statistics and data, to help us assess the patterns and trends of patron question numbers, types, communication modes, and locations in the Terrell Library. With this data, we considered current staffing patterns and how we could best address patron needs.

Results – Researchers found that compiling data across modalities of location, communication, question type, and the READ Scale led to a better understanding of user behavior trends.

Conclusion – Examining and interpreting a more inclusive and richer set of transaction statistics gives reference managers a better picture of how patrons are seeking help, and can serve as a basis for making staffing decisions.

Asymmetric Effects Of Inflation On Stock Market Prices: New Empirical Evidence Using Greek Data
Authors: Constantinos Katrakilidis , Ektor Lake Andreas , Emmanouil Trachanas
Published: February 2016

Since economic theory establishes a relationship between stock market returns and inflation rate, we attempt to re-evaluate the above relationship for Greece considering the possibility of nonlinearities. In particular, empirical analysis is based upon the nonlinear cointegration framework and applies the asymmetric ARDL cointegration methodology, following previous work by Shin, Yu and Greenwood-Nimmo (2011). In doing so, we permit a much richer degree of flexibility in the dynamic adjustment process toward equilibrium, than in the classical case of a linear model. Our findings present evidence of asymmetric adjustment around a unique long-run equilibrium.
The Impact Of Outside Director Equity Compensation On Dividend Policy
Authors: McClain Guy
Published: February 2016

This study investigates the impact outside director equity compensation has on dividend policy. The analysis, conducted over a 4 year period from 1997-2000, is based on a sample of 89 first time adopters of equity compensation. The use of first time adopters attempts to control for the fact that many of the variables in the study are endogenously determined over time. The results indicate that as the percentage of equity compensation increases a firms propensity to pay dividends decreases as does the level of dividends. These results also indicate that firms with higher profitability pay a lower level of dividends. Taken together these result indicate that as managers send signals about positive performance, outside directors with a financial stake in the company decrease the level of monitoring by paying fewer dividends.
Media Independence And Dividend Policy: Evidence From Emerging Stock Markets
Authors: Farooq Omar , Dandoune Salma
Published: February 2016

Can media pressurize managers to disgorge excess cash to shareholders? Do firms in countries with more independent media follow different dividend policies than firms with less independent media? This paper seeks to answer these questions and aims to document the relationship between media independence and dividend policies in emerging markets. Using a dataset from twenty three emerging markets, we show a significantly negative relationship between dividend policies (payout ratio and decision to pay dividend) and media independence. We argue that independent media reduces information asymmetries for stock market participants. Consequently, stock market participants in emerging markets with more independent media do not demand as high and as much dividends as their counterparts in emerging markets with less independent media. We also show that press independence is more important in defining dividend policies than TV independence. Furthermore, our results show that the relationship between media independence and dividend policies is more pronounced in firms that generate greater interest from investors.
The Use Of Capital Budgeting And Cost Of Capital Estimation Methods In Swedish-Listed Companies
Authors: Hartwig Fredrik
Published: February 2016

In this paper Swedish listed companies use of capital budgeting and cost of capital estimation methods in 2005 and 2008 are examined. The relation between company characteristics and choice of methods is investigated and both within-country longitudinal and cross-country comparisons are made. Larger companies seem to have used capital budgeting methods more frequently than smaller companies. When compared to U.S. and continental European companies, Swedish listed companies employed capital budgeting methods less frequently. In 2005 the most common method for establishing the cost of equity was by asking the investors what return they required. By 2008 CAPM was instead the most utilised method, which could indicate greater sophistication. The use of project risk when evaluating investments also seems to have gained in popularity, while the use of company risk declined. Overall, the use of sophisticated capital budgeting and cost of capital estimation methods seem to be rising and the use of less sophisticated methods declining.
Body Image, Confidence, And Media Influence: A Study Of Middle School Adolescents
Authors: Granatino Rachel , Haytko Diana L.
Published: February 2016

For years, we have all been aware of the medias portrayal of the ideal female as unreasonably thin. In recent years, portrayals of males as both thin and muscular have also appeared. While a myriad of research has shown that these images have negative effects on womens body image and self-confidence, few studies have examined what these images do to younger consumers, both female and male. This study examines these issues and also looks at the differences in influence by race. The results show that Hispanic females are the most likely to be influenced, followed by White females. Black females reported no influence. With respect to adolescent boys, only a few reported any influence at all.
Perceived Drivers Of Green Practices Adoption: A Conceptual Framework
Authors: Lee Chai Har , Wahid Nabsiah Abdul , Goh Yen Nee
Published: February 2016

With respect to the rapidly increasing importance of environmental issues, there is a need for businesses from various industries, including the food service industry, to implement initiatives to go green. In Malaysia, green fast-food restaurants are a growing niche. Being green is a strategy to differentiate a business from other competitors in the industry. Being green also indicates a positive response to consumers demand for environmentally friendly organizations. The food service industry, however, appears to be less inclined to adopt green practices than other industries. Most of the literature on green practices investigates the subject matter from consumers perspective, rather than from organizations perspective. This paper provides a conceptual framework on the adoption of the drivers of green practices for fast-food restaurants, with institutional theory as its underlying base. In this paper, perceived internal (i.e., normative pressure) and external drivers (i.e., coercive pressure and mimetic pressure) are considered to be the drivers. Normative pressure is represented by pressure from employees and managers attributes; coercive pressure is represented by regulatory pressure and customer pressure; and mimetic pressure is pressure from competitors. The results of the findings are expected to indicate whether internal and external factors drive the adoption of green practices for fast-food restaurants in Malaysia.
Corporate Governance And Earnings Management: A Survey Of Literature
Authors: Man Chi-keung , Wong Brossa
Published: February 2016

Corporate governance can reduce or even eliminate the extent of earnings management. Normally, an institutional environment that provides better legal protection can control managers self-interest to a certain extent. Takeover force can exert market pressure on managers to do the best for shareholders. Prior studies have investigated different corporate governance mechanisms that can have negative relationships with earnings management. Board independence can enhance certain monitoring behaviors in managers, including the misappropriation of assets. Female directors can develop trust leadership, which requires managers to share information, and are more likely to be risk-averse to frauds and opportunistic earnings management. An audit committee can oversee the internal control for financial reporting and the quality of financial information. Directors with financial expertise can provide incremental control effects on earnings management, especially in firms with weak corporate governance. This paper contributes to corporate governance by providing detailed reviews of different corporate governance mechanisms, reviewing the latest findings on classification shifting, and summarizing earnings management measures, including a new diagnostic system. In the future, this new diagnostic system may be investigated in different contexts.
