To evaluate the impact of a medication therapy management (MTM) program on the clinical outcomes and the quality of life (QoL) of a group of elderly patients with type 2 diabetes mellitus (DM). The study was conducted in a community pharmacy in Aracaju, Brazil, from February to November 2009. A quasi-experimental, longitudinal, prospective study was conducted by intervention. The group patients received medication therapy management from a clinical pharmacist. A sample of convenience was obtained for patients of both genders aged from 60 to 75 years. Monthly visits were scheduled over 10 months. At these consultations, sociodemographic, clinical data were obtained. QoL assessment was conducted using a generic instrument-the Medical Outcomes Studies 36-item Short Form Survey (SF-36 (R)). In total, 34 completed the study. The mean age of the patients was 65.9 (4.7) years. In total, 117 DRPs were identified. Patients' baseline and final evaluation measures for glycosylated hemoglobin, capillary blood glucose, blood pressure, and waist circumference were significantly different (p < 0.05). The domains of QoL assessed by the SF-36 (R) also shows significant differences between patients' baseline and final evaluation scores. The co-responsibility and active participation on the part of the elderly may have helped pharmacotherapy achieve its clinical and humanistic aims.

While there are many articles in the popular press and practitioner journals concerning the Millennials (i.e., who they are and what we need to do about them), the academic literature on the subject is more limited. This chapter (1) extensively reviews this literature as published in practitioner, popular press, and academic journals across disciplines including psychology, sociology, management, human resources, and accounting education, and (2) surveys the generational study literature to determine what, if any, rigorous empirical studies exist to support (or refute) the existence of a distinct Millennial generational cohort. While the popular press is voluminous when it comes to avowed generational differences between Millennials and their predecessors, there is a paucity of peer-reviewed, academic, empirical work in the area and most of the latter suffers in some way from the overarching problem with generational research: the linear relationship between age, period, and generation that results in these variables being inherently entwined. However, even absent strong empirical evidence of a unique generational cohort, the literature offers extensive suggestions about what to do about the Millennials in our classrooms and work places. This paper better informs accounting faculty about the traits of the current generation of accounting students that are supported by empirical research versus claims made in the popular press. It argues for a more reasoned ‘‘continuous improvement’’ approach to Millennials while offering some classroom suggestions for accounting faculty members.

Tef [Eragrostis tef (Zucc.) Trotter] is an important staple food crop, especially in Ethiopia where it is annually grown on 2.8 million hectares of land. It is important for food security in the region, in spite of having a low yield, mainly due to lodging. In this study, 15 representative landraces as well as three improved varieties have been selected for in-depth characterization of many parameters, especially those implicated in yield. The genotypes were clustered into six groups, mainly based on agronomic traits and about 80% of the diversity in the genotypes could be explained on the basis of four principal components. In general, all traits investigated showed substantial diversity among genotypes, offering high chances for improving tef through direct selection or intra-specific hybridization. Moreover, in view of climatic changes, breeding with early maturing landraces such as Red dabi or Karadebi would be advantageous to cope with moisture scarcity during the later stage of crop maturity.

A study with 40 multiparous high yielding dairy cows was conducted to investigate the influence of an induced negative energy balance (NEB) on reproductive performance. Energy restriction of 49% was performed for 3 weeks beginning on oestrous cycle day 12 of first oestrous cycle after day 85 post partum (pp). From day 20 to day 150 pp animals were monitored for ovary activity three times weekly using rectal palpation and transrectal ultrasound scanning and were inseminated around day 150 pp. Additionally, milk progesterone and milk hydrocortisone were analyzed twice a week. Body condition score and body weight as well as blood glucose, plasma nonesterified fatty acids and plasma β-hydroxybutyrate were recorded weekly. According to oestrous cycle activity before (Period 1 = natural energy deficiency), during (Period 2) and after (Period 3) induced energy restriction animals were assigned to the following groups: Delayed first ovulation until day 45 pp, normal oestrous cycle, prolonged oestrous cycle and shortened oestrous cycle. Sporadic significances, but no clear effect of the metabolic state on reproductive performance could be found during Periods 1 and 2. Service success and conception rate were also not influenced. Our results demonstrate a remarkable adaptation of reproductive activity to metabolic challenges. Animals were able to compensate natural NEB in Period 1 as well as induced NEB (Period 2) for preventing metabolic disorders and maintaining reproductive activity. Therefore dietary energy availability had no effect on reproductive performance at more than 85 days in milk in the present study. To understand reproductive failures in dairy cows focus should be laid on genetic disposition of high yielding individuals that cope successful with metabolic challenges.

Over the past few decades, the advantages of the visible-near infra-red (VisNIR) diffuse reflectance spectrometer (DRS) method have enabled prediction of soil organic carbon (SOC). In this study, SOC was predicted using regression models for samples taken from three sites (Gununo, Maybar and Anjeni) in Ethiopia. SOC was characterized in laboratory using conventional wet chemistry and VisNIR-DRS methods. Principal component analysis (PCA), principal component regression (PCR) and partial least square regression (PLS) models were developed using Unscrambler X 10.2. PCA results show that the first two components accounted for a minimum of 96% variation which increased for individual sites and with data treatments. Correlation (r), coefficient of determination (R2) and residual prediction deviation (RPD) were used to rate four models built. PLS model (r, R2, RPD) values for Anjeni were 0.9, 0.9 and 3.6; for Gununo values 0.6, 0.3 and 1.2; for Maybar values 0.6, 0.3 and 0.9, and for the three sites values 0.7, 0.6 and 1.5, respectively. PCR model values (r, R2, RPD) for Anjeni were 0.9, 0.8 and 2.7; for Gununo values 0.5, 0.3 and 1; for Maybar values 0.5, 0.1 and 0.7, and for the three sites values 0.7, 0.5 and 1.2, respectively. Comparison and testing of models shows superior performance of PLS to PCR. Models were rated as very poor (Maybar), poor (Gununo and three sites) and excellent (Anjeni). A robust model, Anjeni, is recommended for prediction of SOC in Ethiopia.

The role of Soil Organic Carbon (SOC) in mitigating climate change, indicating soil quality and ecosystem function has created research interested to know the nature of SOC at landscape level. The objective of this study was to examine variation and distribution of SOC in a long-term land management at a watershed and plot level. This study was based on meta-analysis of three case studies and 128 surface soil samples from Ethiopia. Three sites (Gununo, Anjeni and Maybar) were compared after considering two Land Management Categories (LMC) and three types of land uses (LUT) in quasi-experimental design. Shapiro-Wilk tests showed non-normal distribution (p = 0.002, a = 0.05) of the data. SOC median value showed the effect of long-term land management with values of 2.29 and 2.38 g kg-1 for less and better-managed watersheds, respectively. SOC values were 1.7, 2.8 and 2.6 g kg-1 for Crop (CLU), Grass (GLU) and Forest Land Use (FLU), respectively. The rank order for SOC variability was FLU>GLU>CLU. Mann-Whitney U and Kruskal-Wallis test showed a significant difference in the medians and distribution of SOC among the LUT, between soil profiles (p<0.05, confidence interval 95%, a = 0.05) while it is not significant (p>0.05) for LMC. The mean and sum rank of Mann Whitney U and Kruskal Wallis test also showed the difference at watershed and plot level. Using SOC as a predictor, cross-validated correct classification with discriminant analysis showed 46 and 49% for LUT and LMC, respectively. The study showed how to categorize landscapes using SOC with respect to land management for decision-makers.

El estudio de las revistas especializadas permite comprender aspectos importantes de la dinámica de los campos científicos y académicos. Entre ellos, los grados de institucionalización, diferenciación y especialización o las redes de intercambio. La cantidad, la calidad y la difusión de las revistas expresa, en buena medida, el poder relativo de las diversas comunidades académicas y su influencia en el nivel nacional e internacional. Este estudio realiza un análisis descriptivo de las revistas académicas argentinas especializadas en educación durante la década de 1990, como parte de una investigación más amplia sobre la producción de conocimientos en educación, desarrollada en la FLACSO entre 2002 y 2004. Se presentan los datos y conclusiones del análisis de 17 revistas que refieren exclusivamente a temas de educación y que declaran contar con algún mecanismo de referato científico-académico. La descripción toma como punto de partida las siguientes dimensiones: a) las agencias productoras; b) las referencias temporales (fecha de aparición, frecuencia y regularidad de las revistas); c) la distribución regional; d) la estructura de las publicaciones; d) la pertenencia institucional de los autores y e) los temas abordados en las publicaciones. Al final del artículo, se discuten los avances alcanzados en materia de publicaciones en la década pasada y las dificultades que persisten para consolidar una cantidad y diversidad de instancias de comunicación especializada en el campo de la educación en la Argentina.

Esta tese apresenta uma configuração em que, numa rede social regida pelo princípio da ligação preferencial, nós periféricos buscam inflacionar artificialmente seus índices de centralidade, medida pelo grau de entrada, por meio do privilégio temporário da reciprocidade de ligações com outros nós periféricos. Para construir este cenário, criou-se uma rede com as características de uma rede acadêmica de citações entre artigos, em que os nós são artigos publicados por um conjunto de periódicos, e as ligações entre eles são as citações que cada artigo faz a outros artigos existentes. Esta rede foi condensada em outra, na qual os nós são os periódicos aos quais cada artigo da primeira rede está associado, e as ligações são o total de citações que os artigos de um periódico faz aos artigos de cada outro periódico. Implementou-se um método de simulação computacional, no qual, durante alguns ciclos, foram manipulados parâmetros relacionados à quantidade total de ligações (citações) entre periódicos periféricos, de forma a induzir os efeitos desejados de reciprocidade periférica, alterando a lógica de direcionamento de citações pela atribuição de maior probabilidade para que artigos de outros periódicos periféricos recebessem ligações, afastando-se da lógica da ligação preferencial, porém sem alterar qualquer outra característica intrínseca que representasse a capacidade de um artigo ou periódico atrair novas ligações. Chamou-se esta alteração da lógica de alocação de ligações entre periódicos periféricos de Comportamento Estratégico. Observou-se que o Comportamento Estratégico é capaz de trazer benefícios de centralidade medida por grau para aqueles periódicos em que ele foi induzido, e prejuízos para os demais periódicos periféricos, porém não é suficiente para que eles saiam do quartil periférico de centralidade a que pertenciam antes da manipulação dos efeitos. Além disso, observou-se que, na ausência de elementos que alterem a capacidade intrínseca de atração de ligações de um periódico, a interrupção do Comportamento Estratégico levou aos níveis anteriores de centralidade. Também se observou que o Comportamento Estratégico acarretou em alterações de centralidade medida por autovetor estatisticamente significativas, porém não esperadas, mas que, após sua interrupção, esta retornou aos patamares anteriores à indução dos efeitos.

Purpose – The purpose of this editorial is to provide indicative guidance to prospective EJM contributors of the importance of theoretical development to the success of submissions. Design/methodology/approach – The authors use a combination of conceptual thinking and theoretical literature to present key concepts of theory and its relevance to a manuscript's contribution to knowledge. Findings – The authors propose some guidelines for researchers who wish to publish the results of their work in EJM, and these also have relevance to other top academic journals. Research limitations/implications – The topic of theoretical conceptualisation and development is a complex one. Because of space constraints, the coverage of many issues is necessarily brief in this article. Practical implications – Scholars should find the thoughts contained in this article to be of significant benefit to their publication efforts in EJM and other top journals. Originality/value – While other top marketing journals have in the past provided similar guideline-style pieces, this is one of the few to be written from an inclusive perspective, with the explicit focus on the theoretical development stage.
