Earplug Usage in Preservice Music Teachers
Authors: Walter Jennifer S.
Published: August 2015

In the past 10 years, educating university musicians about hearing protection for long-term career stability and success has become more common, as has the adoption of hearing conservation programs. The purpose of this study was to explore preservice music teachers’ self-reported use of earplugs. Undergraduate preservice teachers ( N = 129) were surveyed and results revealed that 21% ( n = 27) wore earplugs sometimes while practicing, rehearsing, performing, or teaching. While participants recognized that noise-induced hearing loss was preventable ( n = 124, 96%), 88% were seldom or sometimes concerned about their own hearing ( M = 2.39, SD = 1.05). Most participants believed that surgery and hearing aids were ways to correct noise-induced hearing loss ( n = 100, 78%). However, contrary to the preservice teachers’ beliefs, no viable correction is currently available for noise-induced hearing loss. Implications for further education are discussed.

Published: August 2015

The porosity formation in cold metal transfer (CMT) gas metal arc welding (GMAW) of zinc coated steel is studied over a wide range of the heat inputs (160–250 J mm− 1), which shows low porosity in weld bead ( < 2% of bead area) in low ( < 250 J mm− 1) and high (>350 J mm− 1) heat inputs and maximum at medium (250–350 J mm− 1) heat inputs. The high speed imaging of weld pool shows that the highest frequency of zinc vapour escapes at high heat inputs compared to other conditions. Numerous experiments show that size and location of pores along with escaping of zinc vapour are the results of competition of viscosity of weld pool against buoyancy and vapour pressure within the time required to reach solidification temperature. Based on this concept, mechanisms involved in porosity formation, growth and escape phenomena are disclosed, which can help select the optimised welding conditions to obtain porosity free welds in CMT-GMAW of zinc coated steels.

Atom probe tomography (APT) is becoming increasingly applied to understand the relationship between the structure and composition of new alloys at the micro- and nanoscale and their physical properties. Here, we use APT datasets from two modern aerospace alloys to highlight the detailed information available from APT analysis, along with potential pitfalls that can affect data interpretation. The interface between two phases in a Ti–6Al–4V alloy is used to illustrate the importance of parameter choice when using proximity histograms or concentration profiles to characterise interfacial chemistry. The higher number density of precipitates and large number of constituent elements in a maraging steel (F1E) present additional challenges such as peak overlaps that vary across the dataset, along with inhomogeneous interface chemistries.

The role of T cells in the microenvironment of Hodgkin lymphoma
Authors: Wein Frederik , Küppers Ralf
Published: August 2015

The cellular microenvironment in HL is dominated by a mixed infiltrate of inflammatory cells with typically only 1 or a few percent of HRS tumor cells. HRS cells orchestrate this infiltrate by the secretion of a multitude of chemokines. T cells are usually the largest population of cells in the HL tissue, encompassing Th cells, Tregs, and CTLs. Th cells and Tregs presumably provide essential survival signals for the HRS cells, and the Tregs also play an important role in rescuing HRS cells from an attack by CTLs and NK cells. The interference with this complex interplay of HRS cells with other immune cells in the microenvironment may provide novel strategies for targeted immunotherapies.
Chick embryo xenograft model reveals a novel perineural niche for human adipose-derived stromal cells

Published: August 2015

Human adipose-derived stromal cells (hADSC) are a heterogeneous cell population that contains adult multipotent stem cells. Although it is well established that hADSC have skeletal potential in vivo in adult organisms, in vitro assays suggest further differentiation capacity, such as into glia. Thus, we propose that grafting hADSC into the embryo can provide them with a much more instructive microenvironment, allowing the human cells to adopt diverse fates or niches. Here, hADSC spheroids were grafted into either the presumptive presomitic mesoderm or the first branchial arch (BA1) regions of chick embryos. Cells were identified without previous manipulations via human-specific Alu probes, which allows efficient long-term tracing of heterogeneous primary cultures. When grafted into the trunk, in contrast to previous studies, hADSC were not found in chondrogenic or osteogenic territories up to E8. Surprisingly, 82.5% of the hADSC were associated with HNK1+ tissues, such as peripheral nerves. Human skin fibroblasts showed a smaller tropism for nerves. In line with other studies, hADSC also adopted perivascular locations. When grafted into the presumptive BA1, 74.6% of the cells were in the outflow tract, the final goal of cardiac neural crest cells, and were also associated with peripheral nerves. This is the first study showing that hADSC could adopt a perineural niche in vivo and were able to recognize cues for neural crest cell migration of the host. Therefore, we propose that xenografts of human cells into chick embryos can reveal novel behaviors of heterogeneous cell populations, such as response to migration cues.
Class 3 semaphorins negatively regulate dermal lymphatic network formation
Authors: Uchida Yutaka , James Jennifer M. , Suto Fumikazu , Mukouyama Yoh-suke
Published: August 2015

The development of a patterned lymphatic vascular network is essential for proper lymphatic functions during organ development and homeostasis. Here we report that class 3 semaphorins (SEMA3s), SEMA3F and SEMA3G negatively regulate lymphatic endothelial cell (LEC) growth and sprouting to control dermal lymphatic network formation. Neuropilin2 (NRP2) functions as a receptor for SEMA3F and SEMA3G, as well as vascular endothelial growth factor C (VEGFC). In culture, Both SEMA3F and SEMA3G inhibit VEGFC-mediated sprouting and proliferation of human dermal LECs. In the developing mouse skin, Sema3f is expressed in the epidermis and Sema3g expression is restricted to arteries, whereas their receptor Nrp2 is preferentially expressed by lymphatic vessels. Both Sema3f;Sema3g double mutants and Nrp2 mutants exhibit increased LEC growth in the skin. In contrast, Sema3f;Sema3g double mutants display increased lymphatic branching, while Nrp2 mutants exhibit reduced lymphatic branching. A targeted mutation in PlexinA1 or PlexinA2, signal transducers forming a receptor complex with NRP2 for SEMA3s, exhibits an increase in LEC growth and lymphatic branching as observed in Sema3f;Sema3g double mutants. Our results provide the first evidence that SEMA3F and SEMA3G function as a negative regulator for dermal lymphangiogenesis in vivo. The reciprocal phenotype in lymphatic branching between Sema3f;Sema3g double mutants and Nrp2 mutants suggest a complex NRP2 function that regulates LEC behavior both positively and negatively, through a binding with VEGFC or SEMA3s.
The evolution of the dystroglycan complex, a major mediator of muscle integrity
Authors: Adams Josephine C. , Brancaccio Andrea
Published: August 2015

Basement membrane (BM) extracellular matrices are crucial for the coordination of different tissue layers. A matrix adhesion receptor that is important for BM function and stability in many mammalian tissues is the dystroglycan (DG) complex. This comprises the non-covalently-associated extracellular α-DG, that interacts with laminin in the BM, and the transmembrane β-DG, that interacts principally with dystrophin to connect to the actin cytoskeleton. Mutations in dystrophin, DG, or several enzymes that glycosylate α-DG underlie severe forms of human muscular dystrophy. Nonwithstanding the pathophysiological importance of the DG complex and its fundamental interest as a non-integrin system of cell-ECM adhesion, the evolution of DG and its interacting proteins is not understood. We analysed the phylogenetic distribution of DG, its proximal binding partners and key processing enzymes in extant metazoan and relevant outgroups. We identify that DG originated after the divergence of ctenophores from porifera and eumetazoa. The C-terminal half of the DG core protein is highly-conserved, yet the N-terminal region, that includes the laminin-binding region, has undergone major lineage-specific divergences. Phylogenetic analysis based on the C-terminal IG2_MAT_NU region identified three distinct clades corresponding to deuterostomes, arthropods, and mollusks/early-diverging metazoans. Whereas the glycosyltransferases that modify α-DG are also present in choanoflagellates, the DG-binding proteins dystrophin and laminin originated at the base of the metazoa, and DG-associated sarcoglycan is restricted to cnidarians and bilaterians. These findings implicate extensive functional diversification of DG within invertebrate lineages and identify the laminin-DG-dystrophin axis as a conserved adhesion system that evolved subsequent to integrin-ECM adhesion, likely to enhance the functional complexity of cell-BM interactions in early metazoans.
YouTube as a virtual springboard: Circumventing gender dynamics in offline and online metal music careers
Authors: Berkers Pauwke , Schaap Julian
Published: August 2015

Studies have shown that learning to play in a band is largely a peer-based – rather than individual – experience, shaped by existing sex-segregated friendship networks. With the rise of the Internet and do-it-yourself recording techniques, new possibilities have emerged for music production and distribution. As male-dominated offline metal scenes are often difficult to enter for aspiring female metal musicians, online participation might serve as a possibility to circumvent these gender dynamics. This article therefore addresses to what extent female and male musicians navigate online metal scenes differently, and how this relates to the gender dynamics in offline metal scenes. By conducting ten in-depth interviews with women and men who produce vocal covers on YouTube, this article focuses on the understudied relationship between online and offline scene participation. Vocal covers are used for entertainment, skill development, online skill recognition and as a virtual springboard with which women in particular can (partially) circumvent gender inequality by allowing them to (initially) participate as individuals and pursue musical careers in metal music.
The ‘other’ as projection screen: Authenticating heroic masculinity in war-themed heavy metal music videos
Authors: Kartheus Wiebke
Published: August 2015

This article tries to come to terms with Islamophobia as an undercurrent of US culture, heavy metal’s notions of masculinity and authenticity, and the ways in which these two seemingly separate issues intersect in war-themed music videos. By analyzing the official music videos of Metallica’s ‘The Day That Never Comes’ and Lamb of God’s ‘11th Hour’, I will illustrate how the Arab or Muslim ‘other’ is used as a trope to affirm genre-specific notions of masculinity and authenticity. In support of my reading, and to help understand the ways in which music videos are used to communicate with a broader audience, the formal features of the medium will be investigated. Focusing on the structure of my chosen examples and on the way in which meaning-making processes are shaped and perceived by a knowledgeable, pre-informed audience, offers a new perspective to scrutinize the cultural impact of Islamophobic sentiments and shows that they found their way from the mainstream into heavy metal counter-cultures.
‘O body swayed to music’: The allure of Jacqueline du Pré as spectacle and drama
Authors: Curtin Adrian
Published: August 2015

The allure of the British cellist Jacqueline du Pré (1945–1987) is the subject of this article, which examines the spectacle of her playing and the drama of her biography. What motivated the popular and critical responses to du Pré as a performer? What can accounts and depictions of her tell us about how the public personae of classical musicians, and especially female classical musicians, have been constructed? Du Pré’s career and legacy provide insight into multiple discourses including celebrity, classical music, gender, social propriety and disability. I query the operation of apparently ‘extra-musical’ significations that become attached to musicians and affect how they are perceived and understood, both in their lifetimes and afterward. I correlate various accounts of du Pré, drawing on newspaper reviews and magazine articles, observations made by those who knew her, audio-visual documentation and dramatizations of her life – principally the biopic Hilary and Jackie, directed by Anand Tucker (1999). I analyse how du Pré was characterized in dramatic form and portrayed on film. I argue that her persona is multi-layered, collectively authored, and informed by her gender, performance style, and artistic interpretations (or distortions) of her biography. Furthermore, I propose that du Pré’s allure highlights the fascination and anxieties the cello can provoke as a potentially sensual, erotically charged musical instrument.
Gluck the modernist: Pierre Audi’s production of the Iphigénie operas
Authors: Ewans Michael
Published: August 2015

This article examines the productions of Gluck’s Iphigénie en Aulide (1774) and Iphigénie en Tauride (1779), which Pierre Audi staged in Amsterdam in 2011; they were released as a set of two DVDs in 2013. These productions present a radical new vision of Gluck’s last Greek-based operas; far from their being works of neo-classical serenity, Audi encourages us to read them as startlingly modernist psychological dramas of an intensity which is far ahead of its time, and suggests that they are true precursors of Strauss’ Elektra (1909) and Henze’s The Bassarids (1966). The argument is grounded in detailed analysis of Audi’s staging of several crucial scenes in each opera, with particular attention to the two Finales, in which Audi opposes the lieto fine that French operatic convention forced Gluck to adopt.
Memories that remain: Mamma Mia! and the disruptive potential of nostalgia
Authors: Graber Naomi
Published: August 2015

The creators of Mamma Mia! use the music of the 1970s pop group ABBA to create a cheeky response to the postfeminist culture of the 1990s and 2000s. Although most nostalgic culture of that era indicates a yearning for a prefeminist era, by reimaging the culture of the 1970s – the heyday of women’s liberation – the show evinces a nostalgia for the feminist sisterhood of pre-Reagan years, harnessing an emotion normally put to conservative purposes for a progressive cause. The focus on three over-40 female leads who are professional, sexual and unashamed of their feminist pasts, Mamma Mia! participates in ongoing conversations about single motherhood and ageing female bodies within a culture that implicitly holds women increasingly responsible for providing pleasant domestic experiences and pleasing appearances within traditional patriarchical family structures.
Angels talking back and new organs of perception: Art-making and intentionality in nature experience1
Authors: Boeckel Jan van
Published: August 2015

This article focuses on the role of the artistic process in connecting to the natural environment. In my research I have explored what participants experience and learn when they engage in different types of arts-based environmental education (AEE) practices that I have facilitated. The premise of AEE is that efforts to learn about our (natural) environment can effectively take their starting point in an artistic activity, usually conducted in groups. I found that, on the whole, two major orientations can be distinguished. One starts from the point of aesthetic sensibility: the tuning in with the senses, or with ‘a new organ of perception’ (Goethe), in order to perceive ‘the more than human’ with fresh new eyes. This tradition can be traced back (but is by no means limited) to the Romantic Movement. Art in this context may help to amplify the receptivity of the senses and strengthen a sense of connectedness to the natural world. The other major orientation in seeking bridges between nature and art builds on a view of artistic process as leading to unexpected outcomes and ‘emergent properties’. The fundamentally singular experience of making a work of art may evoke an aesthetic object that becomes a ‘self-sufficient, spiritually breathing subject’ (Kandinsky). The artwork can be spontaneously generative and multilayered with meanings, some of which may even be ambiguous and paradoxical. But perhaps more importantly: it can catch the participant of an AEE activity by surprise, overwhelm him or her as ‘coming from behind one’s back’. The element of improvisation, of taking in the new and unanticipated and accommodating for it, is the core quality here. These two orientations, when practiced as part of AEE, have implications on how we relate to nature through art. In the closing of this article I address the question of whether it is possible to bridge the dualism between the two orientations.
From numbers to discourse and action: Visualizing meaning through data as it happens
Authors: Funk Clayton , Castro Juan Carlos
Published: August 2015

The use of data to influence decisions has become near ubiquitous in fields from education to public policy. It has become an instrument to confer validation to policy crafted by those in power. New initiatives to make data widely available have led to new strategies for interpreting and representing derived meaning. Data visualization is one method of interpreting vast amounts of numerical data organized in tabular form. In post-industrialized American culture, having more is often considered as being better than less, but new ways to use macro ideas, termed ‘data visualizations’, can inform individual narratives with other qualities. We illustrate these qualities with data visualizations of cultural phenomena and real-time mapping of the We Are Data (WAD) website to show immediate meaning and emotional response in relationships that emerge in virtual locations. Visualized data, we argue, can provide an event in which one’s preconceived interpretations can either be confirmed or called into question quickly and visually, and as a result, new knowledge emerges.
Art and institutions of power: Fernando Sanchez Castillo’s Arquitectura para el Caballo
Authors: Gessert Rebecca
Published: August 2015

This article models the practice of connecting an artwork to politics, economics, current events and social theory. Basic pictorial elements of Fernando Sanchez Castillo’s short colour video Arquitectura para el Caballo (2002) are discussed in a Marxist framework as representations of capitalist ideology. The article supports the relevancy of Castillo Sanchez’s work in the context of recent anti-austerity protests in Spain, surveys other works by Castillo for themes of power, riot and suppression of riot, briefly discusses architecture and its role in controlling human behaviour and relates Arquitectura to questions surrounding the role higher education plays in supporting capitalist ideology. In the end, the article concludes that Castillo’s work predominantly functions to critically spotlight the normalization of institutions like riot police and the educational system.
Resistance and intervention through a radical ethical aesthetic: The art of Gu Xiong
Authors: Bickel Barbara , Xiong Gu , Irwin Rita L. , Grauer Kit , Beer Ruth
Published: August 2015

This article biographically describes the identity and artistic development of internationally known artist Gu Xiong. Stories of his life during the Cultural Revolution in China and his immigration experience into Canada are expressed and documented through his multiple roles in a community-engaged research study that explores issues of migration, identity, place, displacement, community and the changing nature of geography. Gu Xiong’s unique immigration experiences are contextualized within a mutual encounter of co-shaping between his artist-self and immigrant-self experience. As a cultural worker, created metaphors become the markers of his journey. Despite multiple censorship of his contemporary art and research in his birth country, his approach to creative resistance is a radical ethical aesthetic that unfolds with a neo-vitalist political subjectivity. The outcome is an imminent future vision of hope for a complex world that nourishes individual hybrid identities, interconnected cultures and free societies.
Official Policies and Teachers’ Tendency to Act: Exploring the Discrepancies in Teachers’ Perceptions
Authors: Shapira – Lishchinsky Orly , Gilat Israel Zvi
Published: August 2015

The aim of the study is to investigate whether there are discrepancies between teachers’ perceptions of the ‘official policies’ and their ‘tendency to act,’ based on their ethical decision-making. A qualitative analysis of 60 Israeli teachers’ questionnaires consisting of critical ethical incidents revealed multifaceted ethical dilemmas nested in categories of ‘discrepancies between official policies and teachers’ tendency to act: ‘Harm (to people, property),’ ‘parental involvement/ interference’ and ‘academic process.’ The discrepancies noted between official policy and teachers’ tendency to act may encourage educational policy to design teachers’ training and professional development programs that include dealing with critical ethical incidents, through team-based simulations and formulating ethical guidelines based on their ethical decision-making process.

       By obtaining an important position among the world's largest contracting companies, Turkish contractors undertook  7.371 projects worth of $ 274.1 billion in 103 countries from 1972 to 2013. As of March, 2014, this figure reached to $ 277.7 billion.  From 1972, the sector beginning its overseas journey in Libya,  established trade relations with many countries in 2014.

         Together with 2011 Libyan crisis, many companies had a difficult time and after the end of the crisis, their hopes for stability in the country come an end point. During this period, the sector turning its direction to other markets, managed to come out of the Libyan crisis getting stronger, and with a project worth of $ 26.6 billion, achieved the largest growth.          

         In this study, the Libyan crisis and  the construction sector were tried to be evaluated together, making them to relate with each other. After analyzing domestic and international development of the construction sector and its place in economics, the state of the industry together with  the Libyan crisis was introduced using the data.
The effect of mobbing behaviors on burnout of women’s basketball players
Mobbing davranışlarının kadın basketbolcuların tükenmişliği üzerine etkisi
Authors: Karık Türkan , Yıldız Süleyman Murat
Published: August 2015

This research was conducted in order to examine the effect of mobbing behaviors on the occupational burnout of women’s basketball players. The research mainly looked into the effects of different dimensions of mobbing, namely as person-related mobbing, work-related mobbing and physically intimidating mobbing, on the emergence of emotional/physical exhaustion and devaluation as well as reduced sense of accomplishment among women’s basketball players. 

The study used the NAQ-F (Negative Acts Questionnaire—Football) scale developed by Yildiz (2015a) to measure mobbing and the ABQ (Athlete Burnout Questionnaire) scale developed by Raedeke and Smith (2001) to measure burnout. Data was gathered from a sample of basketball players (n=97) in the Turkish Women’s Premier Basketball League. Exploratory factor analysis, correlation analysis and regression analysis were utilized for the evaluation of data.

The study indicated that person-related mobbing and work-related mobbing had a significant and positive effect on basketball players’ burnout. The emotional/physical exhaustion of basketball players and reduced sense of accomplishment were found to be affected by person-related mobbing while the development of devaluation was positively correlated only with work-related mobbing.

Published: August 2015

Objective

Oxidative stress and mitochondrial dysfunction are implicated in polycystic ovary syndrome (PCOS). The present study assesses the effect of metformin treatment on mitochondrial function in polymorphonuclear cells from PCOS subjects. Additionally, we evaluate endocrine parameters and levels of interleukin 6 (IL6) and tumour necrosis factor alpha (TNFα).

Design and methods

Our study population was comprised of 35 women of reproductive age diagnosed with PCOS and treated with metformin for 12 weeks, and their corresponding controls (n=41), adjusted by age and BMI. We evaluated the alteration of endocrinological and anthropometrical parameters and androgen levels. Mitochondrial O2 consumption (using a Clark-type O2 electrode), membrane potential, mitochondrial mass, and levels of reactive oxygen species (ROS) and glutathione (GSH) (by means of fluorescence microscopy) were assessed in poymorphonuclear cells. H2O2 was evaluated with the Amplex RedR H2O2/Peroxidase Assay kit. IL6 and TNFα were measured using the Luminex 200 flow analyser system.

Results

Metformin had beneficial effects on patients by increasing mitochondrial O2 consumption, membrane potential, mitochondrial mass and glutathione levels, and by decreasing levels of reactive oxygen species and H2O2. In addition, metformin reduced glucose, follicle-stimulating hormone, IL6 and TNFα levels and increased dehydroepiandrosterone sulfate levels. HOMA-IR and mitochondrial function biomarkers positively correlated with ROS production (r=0.486, P=0.025), GSH content (r=0.710, P=0.049) and H2O2 (r=0.837, P=0.010), and negatively correlated with membrane potential (r=−0.829, P=0.011) at baseline. These differences disappeared after metformin treatment.

Conclusions

Our results demonstrate the beneficial effects of metformin treatment on mitochondrial function in leukocytes of PCOS patients.

Published: August 2015

The problem identified in this study is how visitors’ perception and the image communication influenced the overall image of Cirebon as a tourist destination. This study was conducted by using structural equation modelling. The results of this study show that perception variable equation significantly affected the overall image variable, while the image communication variable did not significantly affect the overall image. On the other hand, the causal relationship equation shows that there is a significant relationship between the exogenous latent variable of perception and endogenous latent variable of Overall Image. While there is no relationship between exogenous latent variable of image Communication with endogenous variable of overall image. The result is expected to give recommendation to the local government to develop and promote tourism that at the end can put tourism to generate income for the city.DOI: 10.15408/etk.v11i1.1872

Objective To investigate somatosensory deficits in the ipsilesional wrist and hand in chronic stroke patients and correlate these deficits with contralesional sensorimotor dysfunctions, functional testing, laterality and handedness.Methods Fifty subjects (twenty-two healthy volunteers and twenty-eight stroke patients) underwent evaluation with Semmes-Weinstein monofilaments, the sensory and motor Fugl-Meyer Assessment, the Nottingham Sensory Assessment in both wrists and hands and functional tests.Results Twenty-five patients had sensory changes in the wrist and hand contralateral to the stroke, and eighteen patients (64%) had sensory deficits in the ipsilesional wrist and hand. The most significant ipsilesional sensory loss was observed in the left-handed patients. We found that the patients with brain damage in the right hemisphere had better scores for ipsilesional tactile sensation.Conclusions A reduction in ipsilesional conscious proprioception, tactile or thermal sensation was found in stroke subjects. Right hemisphere damage and right-handed subjects had better scores in ipsilesional tactile sensation.

Purpose To analyze the effectiveness of electroconvulsive therapy for the management of depression and/or psychosis refractory to drug therapy in patients with Parkinson disease.Methods A retrospective study was carried out including patients treated with electroconvulsive therapy during the period between 2002 and 2013. A review of the literature was performed.Results A total of 27 patients were included. In regards to the neuropsychiatric diagnosis, 14 patients had major depression, 12 patients had both psychosis and depression, and only one patient had isolated psychosis. The mean number of electroconvulsive therapy sessions was 12 ± 2.8. After electroconvulsive therapy, all patients showed a statistically significant improvement in the Brief Psychiatric Rating scale (reduction of 52% points) and Hamilton Depression Rating Scale (reduction of 50% points) independent of the presence of psychosis, depression or both.Conclusion Electroconvulsive therapy is effective for the treatment of refractory neuropsychiatric symptoms in Parkinson’s disease.

Amyotrophic lateral sclerosis is a progressive neuromuscular disease, resulting in respiratory muscle weakness, reduced pulmonary volumes, ineffective cough, secretion retention, and respiratory failure. Measures as vital capacity, maximal inspiratory and expiratory pressures, sniff nasal inspiratory pressure, cough peak flow and pulse oximetry are recommended to monitor the respiratory function. The patients should be followed up by a multidisciplinary team, focused in improving the quality of life and deal with the respiratory symptoms. The respiratory care approach includes airway clearance techniques, mechanically assisted cough and noninvasive mechanical ventilation. Vaccination and respiratory pharmacological support are also recommended. To date, there is no enough evidence supporting the inspiratory muscle training and diaphragmatic pacing.

RESUMOEste estudo teve por objetivo analisar como a distribuição e riqueza de espécies raras em fragmentos de Floresta Ombrófila Mista ocorrem ao longo de um gradiente altitudinal. Para isso, espécies arbóreas (diâmetro à altura do peito > 5 cm) foram amostradas em 10 fragmentos florestais localizados em diferentes pisos altitudinais do Planalto Sul-Catarinense, em uma área total de 10 ha. As espécies que apresentaram número de indivíduos igual ou inferior a 2 em pelo menos um fragmento foram classificadas como raras. A distribuição das espécies foi verificada por meio de dendrograma construído a partir do índice de distância florística de Jaccard e do algoritmo de agrupamento UPGMA. A riqueza total de espécies por fragmento e o número de espécies raras foram comparados entre as subformações montana e alto-montana, por meio do teste de Mann-Whitney (U). As relações entre altitude e os valores de riqueza total e número de espécies raras em cada fragmento foram determinadas por regressões lineares simples. Os resultados indicaram a formação de dois grandes grupos de espécies raras em função do piso altitudinal. Apesar de a riqueza total das comunidades reduzir com o aumento da altitude, o número de espécies raras não apresentou alterações significativas. Conclui-se que na região do Planalto Sul-Catarinense os fragmentos de Floresta Ombrófila Mista apresentam diferentes conjunto de espécies arbóreas raras de acordo com a altitude e que a diminuição da riqueza das comunidades com o aumento do piso altitudinal não é acompanhada pela redução do número de espécies raras.

ABSTRACTCallisthene fasciculata Mart. is a tree belonging to the Vochysiaceae family. Its wood is moderately heavy and resistant and used to make poles, beams, and other structures. The aim of this work was to evaluate seed germination and the initial growth of seedlings of C. fasciculata at different temperatures and in different substrates. Seeds were collected from fruits in the Pantanal de Miranda, Mato Grosso do Sul state, Brazil. In one experiment, the seeds were subjected to constant temperatures of 20, 25, 30 and 35 °C and to alternating temperatures of 20-30 and 25-35 °C (on paper substrate). In another experiment, the seeds were subjected to temperatures of 20 and 25 °C on three substrates (sand, vermiculite and between paper) in a germinator. The experiment had a randomized design, with four replicates of 25 seeds per treatment. The F-values obtained for germination indicated no significant effect of substrate or temperature on the final germination percentage. The analyses revealed no effect of a treatment interaction (temperature x substrate) on either germination or average germination time; however, a treatment interaction effect was observed on the germination speed index. The treatment combinations yielding the best performance were between paper substrate at 20 °C and sand substrate at 25 °C. There was a significant effect of the interaction between temperature and substrate on seedling growth, with increased root growth observed in the between paper substrate at 25 °C and increased aerial component growth in both sand at 20 °C and vermiculite at 25 °C. The between paper treatment at 25 °C yielded the greatest final seedling size. Between paper is the most recommended substrate for the production of seedlings due to its ease of handling and lower probability of contamination.

ABSTRACTWe aimed to evaluate the technical efficiency of mini-cuttings technique on vegetative propagation of Paulownia fortunei (Seem.) Hemsl. var. Mikado, as well as the possible existence of anatomical barriers to its rooting. Therefore, plants originated from cuttings formed the mini-stumps and, consequently the clonal mini-garden, which was conducted in semi-hydroponic system. We evaluated the survival of mini-stumps and sprouts production for five successive collects, the percentage of mini-cuttings rooting and their anatomical description. The mini-cuttings were prepared with about 6 to 8 cm in length and two leaves reduced by about 50% in the upper third, being remained an area of, approximately 78 cm2 (10 cm diameter). The mini-cuttings were placed in tubes of 53 cm3, with substrate formed with fine vermiculite and carbonized rice hulls (1:1 v/v) and rooted in acclimatized greenhouse. After 30 days we evaluated the percentage of rooted mini-cuttings, radicial vigor (number and length of roots / mini-cutting), callus formation, emission of new shoots and maintenance of the original leaves. The mini-stumps showed 100% survival after five collects and an average production of 76-114 mini-cuttings/m2/month and rooting ranged from 70 to 90%. Mini-cuttings technique is efficient in to propagate adult propagules of the species and there are not anatomical barriers preventing roots emission.
