This study discusses the importance of internal communication during organizational change of a case study company X. The purpose of this study is to find out how to use internal communication effectively during organizational change. This study is an ethnographic cade study where a unique case of an organizational change was chosen as the research object. The theoretical background of this study consists of literature relating to the concepts of communication, organizational communication, organizational change, change management and communication of change. The empirical research conducted for this study is based on an ethnographic research method where data was collected through participant observation, informal interviews and field records in the form of a research diary. The research data was collected between September and December 2015. During this period the researcher was working within the case study organization while observing the internal communication during the organizational change process. Triangulation was used to analyze the research data in order to build a united and theoretical picture of the topic. The study finds that without clear internal communication strategy the effectiveness of communication is ought to be poor, which may lead to resistance of change, lack of trust and lower level of overall job satisfaction. Moreover the study findings highlight the importance of managerial presence during an organizational change process and consistency in using formal and informal communication and utilizing multiple communication channels. Based on the findings of this research the study suggests that during an organizational change process a clear internal communication strategy should be carefully planned and executed. The goals of internal communication should be clearly stated and communicated to the company’s employees. The findings of this study enhance importance of managers promoting sense of belonging, developing awareness of the overall change process and contributing to the manager employee relationships and trust. In addition this study points out the key factors that should be included in the internal change communication strategy which are how to ensure that the communications, both vertical and horizontal, are constant. Future research is however necessary in order to gain a more comprehensive view of the research and wider perspective of the case study. Nevertheless, this study deepens the understanding of how to use internal communication effectively during organizational change.

OBJETIVOS: Describir y comparar los cambios dinámicos de la geometría del anillo mitral durante todo el ciclo cardiaco en pacientes con insuficiencia mitral isquémica y pacientes con válvula mitral normal. MATERIALES Y MÉTODOS: Los estudios ecocardiográficos analizados fueron 37, 23 con insuficiencia mitral isquémica y 14 con válvula mitral normal. La reconstrucción del anillo se realizó en la estación de trabajo Xcelera (Philips Medial Systems) mediante la herramienta de análisis mitral (MVQ), en 5 momentos del ciclo cardiaco: Comienzo de Sístole, Mitad de Sístole, Final de Sístole, Mitad de Diástole y Final de Diástole. RESULTADOS: El anillo del grupo control, fue más dinámico, con sus menores dimensiones al final de la diástole, presentando incremento progresivo durante la sístole. Los cambios en el perímetro y el área, fueron significativos entre el comienzo y mitad de la sístole (p:0.087 y p: 0.055). En el grupo con insuficiencia mitral isquémica, el anillo fue más estático. Todas las dimensiones en este grupo, fueron mayores en los cinco momentos del ciclo cardiaco. (p < 0.1). El anillo también fue más plano, con un índice morfológico anular menor al del grupo control (p:0.087). DISCUSIÓN Y CONCLUSIONES: En pacientes sin insuficiencia mitral, el anillo es una estructura dinámica. Durante la sístole, las menores dimensiones se produjeron al comienzo de este periodo y la conformación en silla de montar se mantuvo, protegiendo contra la insuficiencia mitral. El anillo del grupo con insuficiencia mitral fue más estático y plano, perdiendo los mecanismos protectores.

La industria de las centrales de llamadas es uno de los sectores de más rápido crecimiento en el mundo desarrollado, gracias a los avances tecnológicos han permitido su uso cada vez más generalizado desarrollando servicios integrales que son accesibles las 24 horas del día. Los operadores telefónicos o tele-operadores de esta industria se ven enfrentados a jornadas laborales en las que se exponen al uso constante de la voz, utilización permanente de auriculares de comunicación, confinamiento en estaciones de trabajo delimitadas pero no aisladas; aumentando así la prevalencia de síntomas como los otorrinolaringológicos. Este estudio tiene como objeto identificar la prevalencia de síntomas otorrinolaringológicos dados por alteraciones de la voz, compromiso auditivo y síntomas de la vía respiratoria superior durante la jornada laboral de los trabajadores de una central de llamadas de una prestigiosa empresa aseguradora de la ciudad de Bogotá Colombia, así como también identificar la asociación de factores demográficos organizacionales y biológicos con los síntomas otorrinolaringológicos y analizar el medio ambiente laboral de dicha empresa y la relación de los síntomas otorrinolaringológicos con mediciones de ruido, temperatura y humedad. La población estudiada fue de 81 tele operadores de los cuales 61 (75.3%) fueron mujeres, se evidencio que las enfermedades respiratorias altas tienen una prevalencia del 36%, también se reporto una prevalencia del 85% (69) tele operadores reportaron por lo menos un síntoma de voz y solo 12 tele operadores 15% no reportaron ningún síntoma. En cuanto a la hipoacusia solo 5 (6.2%) reportaron disminución de la agudeza auditiva

El liderazgo ha sido definido de diferentes maneras por cientos de autores debido al contexto en el que estudian este concepto. Ninguna de estas definiciones es errónea pero algunas han tomado mayor importancia debido a los diferentes factores que enfrenta la sociedad. Desde hace unos años los países se han abierto a diferentes mercados lo cual les ha permitido eliminar las barreras políticas, económicas y culturales existentes. Esto ha llevado a que los líderes deban evaluar la nueva forma de dirigir y direccionar las organizaciones. Este es tan solo uno de los ejemplos que han llevado a modificar el concepto de liderazgo, añadiendo los nuevos retos a los que se ven enfrentados los líderes. En este trabajo de grado se estudia el que se considera uno de los mayores retos de los siglos XX y XXI: la globalización. Este fenómeno ha acercado al mundo a través del intercambio de información, de bienes, de servicios, de conocimientos y sobre todo de cultura. Esto se ha logrado a través de nuevas tecnologías, nuevos servicios de comunicación y transporte, de la ciencia y los avances de la industria. El nuevo líder debe romper la barrera nacional y abrirse a mercados extranjeros, para esto debe contar con ciertas características que le permitirán entender los diferentes mercados y a las personas que se encuentran en este. En este trabajo se identifican las que se consideran las principales características de un líder global; estas son el resultado de la investigación de diferentes autores y estudios.

The paper explores pollination from a multi level policy perspective and analyses the institutional fit and inter play of multi-faceted pollination-related policies. First, it asks what the major policies are that frame pollination at the EU level. Second, it explores the relationship between the EU policies and localised ways of understanding pollination. Addressed third is how the concept of ecosystem services can aid in under- standing the various ways of framing and governing the situation. The results show that the policy systems affecting pollination are abundant and that these systems create different kinds of pressure on stakeholders, at several levels of society. The local-level concerns are more about the loss of pollination services than about loss of pollinators. This points to the problem of fit between local activity driven by economic reasoning and biodiversity-driven EU policies. Here we see the concept of ecosystem services having some potential, since its operationalisation can combine economic and environmental considerations. Further- more, the analysis shows how, instead of formal institutions, it seems that social norms, habits, and motivation are the key to understanding and developing effective and attractive governance measures.

AIMS: To identify the rates and reasons for plate removal (PR) among patients treated for facial fractures. MATERIALS AND METHODS: A retrospective review of files of 238 patients. RESULTS: Forty-eight patients (20.2%) had plates removed. The reason for removal was objective in 33.3% and subjective in 29.2%. The most common subjective reason was cold sensitivity, and the most common objective reason was wound dehiscence/infection. Women had PR for subjective reasons more often than men (p=0.018). Removal was performed more often for subjective reasons after zygomatico-orbital fractures than after mandibular fractures (p=0.002). Plates inserted in the mandible from an intraoral approach were removed more frequently than extraorally inserted mandibular plates, intraorally inserted maxillary plates, and extraorally inserted plates in other locations (p<0.001). Orbital rim plates had a higher risk of being removed than maxillary or frontal bone plates (p=0.02). CONCLUSIONS: Subjective discomfort is a notable reason for PR among Finnish patients, suggesting that the cold climate has an influence on the need for removal. Patients receiving mandibular osteosynthesis with miniplates from an intraoral approach are at risk of hardware removal because of wound dehiscence/infection and loose/broken hardware, reminding us that more rigid fixation devices should not be forgotten despite the widespread use of miniplates.

PURPOSE: To identify the occurrence, types, and severity of associated injuries outside the facial region among patients diagnosed with facial fractures, and to analyze whether there are any factors related to associated injuries. MATERIALS AND METHODS: This was a cross-sectional study of 401 patients diagnosed with facial fractures during the 2-year period from 2003 to 2004. RESULTS: Associated injuries were observed in 101 patients (25.2%). The most common type of injury was a limb injury (13.5%), followed by brain (11.0%), chest (5.5%), spine (2.7%), and abdominal (0.8%) injuries. Multiple associated injuries were observed in 10% and polytrauma in 7.5%. The mortality rate was 0.2%. The occurrence of associated injury correlated significantly with trauma mechanism and fracture type; high-speed accidents and severe facial fractures were significant predictors of associated injury. CONCLUSIONS: Associated injuries are frequent among patients who have sustained facial fractures. The results underscore the importance of multiprofessional collaboration in diagnosis and sequencing of treatment, but also the importance of arranging appropriate clinical rotations for maxillofacial residents in training.

The widespread use of artificial nestboxes has led to significant advances in our knowledge of the ecology, behaviour and physiology of cavity nesting birds, especially small passerines Nestboxes have made it easier to perform routine monitoring and experimental manipulation of eggs or nestlings, and also repeatedly to capture, identify and manipulate the parents However, when comparing results across study sites the use of nestboxes may also Introduce a potentially significant confounding variable in the form of differences in nestbox design amongst studies, such as their physical dimensions, placement height, and the way in which they are constructed and maintained However, the use of nestboxes may also introduce an unconsidered and potentially significant confounding variable clue to differences in nestbox design amongst studies, such as their physical dimensions, placement height, and the way in which they are constructed and maintained Here we review to what extent the characteristics of artificial nestboxes (e g size, shape, construction material, colour) are documented in the 'methods' sections of publications involving hole-nesting passerine birds using natural or excavated cavities or artificial nestboxes for reproduction and roosting Despite explicit previous recommendations that authors describe in detail the characteristics of the nestboxes used, we found that the description of nestbox characteristics in most recent publications remains poor and insufficient We therefore list the types of descriptive data that should be included in the methods sections of relevant manuscripts and justify this by discussing how variation in nestbox characteristics can affect or confound conclusions from nestbox studies We also propose several recommendations to improve the reliability and usefulness of research based on long-term studies of any secondary hole-nesting species using artificial nestboxes for breeding or roosting.

Pollinating insects form a key component of European biodiversity, and provide a vital ecosystem service to crops and wild plants. There is growing evidence of declines in both wild and domesticated pollinators, and parallel declines in plants relying upon them. The STEP project (Status and Trends of European Pollinators, 2010-2015, www.step-project.net) is documenting critical elements in the nature and extent of these declines, examining key functional traits associated with pollination deficits, and developing a Red List for some European pollinator groups. Together these activities are laying the groundwork for future pollinator monitoring programmes. STEP is also assessing the relative importance of potential drivers of pollinator declines, including climate change, habitat loss and fragmentation, agrochemicals, pathogens, alien species, light pollution, and their interactions. We are measuring the ecological and economic impacts of declining pollinator services and floral resources, including effects on wild plant populations, crop production and human nutrition. STEP is reviewing existing and potential mitigation options, and providing novel tests of their effectiveness across Europe. Our work is building upon existing and newly developed datasets and models, complemented by spatially-replicated campaigns of field research to fill gaps in current knowledge. Findings are being integrated into a policy-relevant framework to create evidence-based decision support tools. STEP is establishing communication links to a wide range of stakeholders across Europe and beyond, including policy makers, beekeepers, farmers, academics and the general public. Taken together, the STEP research programme aims to improve our understanding of the nature, causes, consequences and potential mitigation of declines in pollination services at local, national, continental and global scales.

One quadrillion synapses are laid in the first two years of postnatal construction of the human brain, which are then pruned until age 10 to 500 trillion synapses composing the final network. Genetic epilepsies are the most common neurological diseases with onset during pruning, affecting 0.5% of 2-10-year-old children, and these epilepsies are often characterized by spontaneous remission. We previously described a remitting epilepsy in the Lagotto romagnolo canine breed. Here, we identify the gene defect and affected neurochemical pathway. We reconstructed a large Lagotto pedigree of around 34 affected animals. Using genome-wide association in 11 discordant sib-pairs from this pedigree, we mapped the disease locus to a 1.7 Mb region of homozygosity in chromosome 3 where we identified a protein-truncating mutation in the Lgi2 gene, a homologue of the human epilepsy gene LGI1. We show that LGI2, like LGI1, is neuronally secreted and acts on metalloproteinase-lacking members of the ADAM family of neuronal receptors, which function in synapse remodeling, and that LGI2 truncation, like LGI1 truncations, prevents secretion and ADAM interaction. The resulting epilepsy onsets at around seven weeks (equivalent to human two years), and remits by four months (human eight years), versus onset after age eight in the majority of human patients with LGI1 mutations. Finally, we show that Lgi2 is expressed highly in the immediate post-natal period until halfway through pruning, unlike Lgi1, which is expressed in the latter part of pruning and beyond. LGI2 acts at least in part through the same ADAM receptors as LGI1, but earlier, ensuring electrical stability (absence of epilepsy) during pruning years, preceding this same function performed by LGI1 in later years. LGI2 should be considered a candidate gene for common remitting childhood epilepsies, and LGI2-to-LGI1 transition for mechanisms of childhood epilepsy remission.

BACKGROUND: Usher syndrome, a combination of retinitis pigmentosa (RP) and sensorineural hearing loss with or without vestibular dysfunction, displays a high degree of clinical and genetic heterogeneity. Three clinical subtypes can be distinguished, based on the age of onset and severity of the hearing impairment, and the presence or absence of vestibular abnormalities. Thus far, eight genes have been implicated in the syndrome, together comprising 347 protein-coding exons. METHODS: To improve DNA diagnostics for patients with Usher syndrome, we developed a genotyping microarray based on the arrayed primer extension (APEX) method. Allele-specific oligonucleotides corresponding to all 298 Usher syndrome-associated sequence variants known to date, 76 of which are novel, were arrayed. RESULTS: Approximately half of these variants were validated using original patient DNAs, which yielded an accuracy of >98%. The efficiency of the Usher genotyping microarray was tested using DNAs from 370 unrelated European and American patients with Usher syndrome. Sequence variants were identified in 64/140 (46%) patients with Usher syndrome type I, 45/189 (24%) patients with Usher syndrome type II, 6/21 (29%) patients with Usher syndrome type III and 6/20 (30%) patients with atypical Usher syndrome. The chip also identified two novel sequence variants, c.400C>T (p.R134X) in PCDH15 and c.1606T>C (p.C536S) in USH2A. CONCLUSION: The Usher genotyping microarray is a versatile and affordable screening tool for Usher syndrome. Its efficiency will improve with the addition of novel sequence variants with minimal extra costs, making it a very useful first-pass screening tool.

Research in autophagy continues to accelerate,(1) and as a result many new scientists are entering the field. Accordingly, it is important to establish a standard set of criteria for monitoring macroautophagy in different organisms. Recent reviews have described the range of assays that have been used for this purpose.(2,3) There are many useful and convenient methods that can be used to monitor macroautophagy in yeast, but relatively few in other model systems, and there is much confusion regarding acceptable methods to measure macroautophagy in higher eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers of autophagosomes versus those that measure flux through the autophagy pathway; thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from fully functional autophagy that includes delivery to, and degradation within, lysosomes (in most higher eukaryotes) or the vacuole (in plants and fungi). Here, we present a set of guidelines for the selection and interpretation of the methods that can be used by investigators who are attempting to examine macroautophagy and related processes, as well as by reviewers who need to provide realistic and reasonable critiques of papers that investigate these processes. This set of guidelines is not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to verify an autophagic response.
