A Monograph of Operculina (Convolvulaceae)

A comprehensive systematic monograph is presented for the genus Operculina Silva Manso (Convolvulaceae). Formerly included in tribe Merremieae D. F. Austin, now incertae sedis, recent systematic studies have clarified the phylogenetic relationships for Operculina and unequivocally demonstrated that it is monophyletic as currently circumscribed and that the unique operculate capsule is a synapomorphy for the genus. Other morphological characters useful for recognizing the genus are: large sepals forming a “pear-shaped” calyx that is broad at the base and tapers upward; calyx that is accrescent and persistent, often cupping the mature fruit; strongly spirally coiled anthers after dehiscence; and axial parts of the plant body (stems, petioles, peduncles, pedicels) that are often prominently winged. The current monograph accepts 13 species, including one variety and one purported hybrid; these taxa are distributed throughout the tropics globally. The hybrid is proposed to accommodate the extraordinary phenotypic variability and intermediacy among South Pacific populations of Operculina. The monograph provides detailed descriptions for all taxa, as well as an identification key, distribution maps, and summaries of ecology, phenology, vernacular names, and uses, with comments on synonymy, typification, variability, biology, and conservation, where appropriate. All names published or combined in Operculina (about 60 epithets) are accounted for as accepted names, synonyms, misapplied names, or uncertain names, or are excluded from the genus. New reductions to synonymy are proposed as follows: O. brownii Ooststr. becomes a synonym of O. codonantha (Benth.) Hallier f. ; O. tansaensis Santapau & V. Patel becomes a synonym of O. ventricosa (Bertero) Peter. Lectotypes, neotypes, and epitypes are designated where necessary to stabilize names in current use. An index to numbered collections examined is provided to aid in specimen identification and herbarium curation.
Physical and chemical properties associated with food quality in sorghum

Samples of 13 genetically diverse sorghum [Sorghum bicolor (L.) Moench] accessions were analysed for physical properties and chemical composition. The food (injera) quality and the phenolic (condensed tannins) content of six sorghum samples were also determined. The accessions showed a wide variation in protein (7.99 to 17.8%), lipids (2.52 to 4.76%), starch (51.88 to 85%), and amylose (12.30 to 28.38%) content. Grain weight varied in a wide range, and endosperm texture varied from intermediate to completely starchy. Linoleic acid (18:2) and oleic acid (18:1) were the major fatty acid constituents of sorghum lipids. Only a few significant correlations were observed among the physical and chemical properties. Three of the six accessions used for sensory analysis, namely Ambajeettee, AL-70 and ETS 2752 were chosen for their desirable properties in injera making. The chemical and physical properties of the selected accessions were characterised by high protein content, low tannins, intermediate endosperm texture, and white seed colours. Red seeded sorghum and white seeded sorghum with pigmented testa were found to be less desired.
Seed germination and antioxidant enzyme activity in seedlings of diploid and tetraploid bahiagrass under water restriction

ABSTRACT: The objective of the following research was to investigate the physiological responses of two bahiagrass genotypes (Paspalum notatum Flügge) submitted to water restriction, induced by polyethylene glycol (PEG6000), during seed germination. Seeds of cv. Pensacola (diploid) and Bagual ecotype (tetraploid) were placed on paper moistened with osmotic solutions at potentials of 0.0; -0.1; -0.2 and -0.3 MPa. Composed of two subsamples of 100 seeds and four experimental units per treatment, the germination test was conducted in a germination chamber under alternating temperatures of 30 °C (8 hours) and 20 °C (16 hours), with presence of light during the higher temperature. Final germination percentage and germination speed index of the seeds, as well as early growth, activity and expression of antioxidant enzymes of seedlings were evaluated. The water restriction induced by PEG6000 reduced the percentage of germination in Pensacola (from 74% to 59%) and Bagual (34% to 10%). For the latter, the evaluation of seedlings showed higher dry mass in relation to cv. Pensacola (1.7 times higher in root and 1.6 times in shoot). In response to moderate water restriction, the genotypes showed increases in root growth (1.7 times higher in -0.1 compared to 0.0 MPa), both in expression and enzymatic activity (superoxide dismutase and catalase).
Efficacy Beliefs Are Related to Task Cohesion: Communication Is a Mediator

1 Efficacy beliefs and communication are key constructs which have been targeted to 2 develop task cohesion. This study’s purpose was to: (1) examine whether collective efficacy, 3 team-focused other-efficacy, and team-focused relation-inferred self-efficacy (RISE) are 4 predictive of task cohesion, and (2) evaluate the possibility that communication mediates 5 efficacy-task cohesion relationships. British university team-sport athletes ( n = 250) 6 completed questionnaires assessing efficacy beliefs, communication (i.e., positive conflict, 7 negative conflict, and acceptance communication), and task cohesion (i.e., attractions to 8 group; ATG-T, group integration; GI-T). Data were subjected to a multi-group path analysis 9 to test mediation hypotheses while also addressing potential differences across males and 10 females. Across all athletes, collective efficacy and team-focused other-efficacy significantly 11 predicted ATG-T and GI-T directly. Positive conflict and acceptance communication 12 significantly mediated relationships between efficacy (team-focused other-efficacy, collective 13 efficacy) and cohesion (ATG-T, GI-T). Findings suggest enhancing athletes’ collective 14 efficacy and team-focused efficacy beliefs will encourage communication factors affecting 15 task cohesion. 16 17
International Perspectives on Local Government and Housing: The Australian Case in Context

ABSTRACT This paper examines the role of local government in the provision of housing across advanced economies in the contemporary economy and historically, while seeking to locate the Australian experience in a broader international perspective. The paper finds that ongoing challenges have given rise to policy innovation and new programmatic perspective. These developments have reflected non-systematic, and often disruptive, change rather than the continuation of predictable trends. The paper argues such evolution will continue and will be more likely to deliver benefits to the local government sector and housing affordability if acknowledged and enabled by more senior tiers of government. 本文探讨了在当代经济和历史上的发达经济体中，地方政府在提供住房方面的作用，同时试图从更广阔的国际视角来定位澳大利亚的经验. 报告发现，持续的挑战带来了政策创新和新的规划视角. 这些发展反映了非系统的、往往是破坏性的变化，而不是可预测的趋势的继续. 该论文认为，这种演变将继续下去，如果得到更高层政府的承认和支持，将更有可能为地方政府部门和住房负担能力带来好处.
When You CAN See the Difference: The Phonetic Basis of Sonority in American Sign Language

Spoken and signed languages (SL) deliver perceptual cues which exhibit various degrees of perceptual validity during categorization: In spoken languages, listeners develop perceptual biases when integrating multiple acoustic dimensions during auditory categorization (Holt & Lotto, 2006). This leads us to expect differential perceptual validity for dynamic gestural units HANDSHAPE, MOVEMENT, ORIENTATION, and LOCATION produced by manual articulators in SLs. In this study, we use a closed-set sentence discrimination task developed by Bochner et al. (2011) to evaluate the perceptual saliency of the gestural components of signs in American Sign Language (ASL) for naive signers and deaf L2 learners of ASL proficient in another SL. Our goal is to gauge which of these features are likely to present the phonetic basis of sonority in sign modality and relay phonemic contrasts perceptible for even first-time signers. 25 deaf L2 ASL signers and 28 hearing English speakers with no experience in any SL participated in this study. Results reveal that phonemic contrasts based on HANDSHAPE presented an area of maximum difficulty in phonological discrimination for sign-naive participants. For all participants, contrasts based on ORIENTATION and LOCATION and involving larger scale articulators, were associated with robust categorical discrimination.
Light Quality and the Critical Period for Weed Control in Soybean

Abstract The critical period for weed control (CPWC) is an integral component of integrated weed management strategies. Several studies have defined the CPWC in soybean under varying agronomic conditions, yet none have described the mechanisms involved in crop yield losses caused by weed competition. We hypothesized that under nonresource-limiting conditions, morphological changes resulting from the expression of shade avoidance could be used to define a period of developmental sensitivity to low red-to-far-red ratio (R ∶ FR) that would overlap with the defined CPWC in soybean. Two experiments (a sequential harvest and a weed addition/removal series) were conducted in 2008 and 2009 under controlled environmental conditions to address this hypothesis. Two light-quality treatments were used: (1) high R ∶ FR ratio (i.e., weed-free), and (2) low R ∶ FR ratio (i.e., weedy). The low R ∶ FR ratio treatment induced shade avoidance responses in soybean, which included increases in height, internode length, and the shoot ∶ root ratio, as well as a reduction in biomass accumulation and leaf number. Using the morphological changes in biomass and leaf number observed in the weed addition/removal series, a period of developmental sensitivity to low R ∶ FR was defined between the first trifoliate (V1) and third trifoliate (V3) stages of soybean development. This period was found to be very similar to the CPWC previously defined by field studies of soybean–weed competition. Nomenclature: Soybean, Glycine max (L.) Merr.
The Use and Misuse of Neutral Landscape Models in Ecology

Neutral landscape models (NLMs) were developed from percolation theory nearly a decade ago. Since then, the original random percolation maps have undergone adaptive radiation and NLMs now include a diverse array of spatially explicit models based on theoretical distributions derived from fractal geometry and spectral synthesis. The purpose of NLMs is to provide null models of landscape structure as a baseline for comparison with real landscape patterns, or for evaluating the effects of landscape structure on ecological processes. As the use of NLMs has expanded beyond the domain of theoretical landscape ecology to applications in other areas of ecology, there is an increased risk that NLMs will be used inappropriately, or that their function will be misunderstood or misinterpreted. NLMs are being subjected to the same general criticisms levied against null models in other areas of ecology. For this reason, we clarify the purpose of NLMs, review the contributions of NLMs to ecology, and evaluate the appropriate use of NLMs in ecological research. NLMs have already made several contributions to ecology: (I) development of spatial indices to describe landscape patterns; (2) prediction of critical thresholds in ecological phenomena; (3) definition of landscape connectivity; (4) development of species' perceptions of landscape structure; (5) provision of a general model of spatial complexity; and (6) determination of the ecological consequences of spatial heterogeneity. In the future, emphasis on NLMs should shift from theoretical development to application and model testing.
IN VITRO FERTILIZATION OF IN VITRO MATURED MINKE WHALE (BALAENOPTERA ACUTOROSTRATA) FOLLICULAR OOCYTES

In vitro fertilization of follicular oocytes harvested from ovaries and matured in vitro was attempted for 55 minke whales (Balaenoptera acutorostrata) captured for Japanese research purposes in the Antarctic Ocean during the period from November 1995 to March 1996. In Experiment 1, effects of culture duration (96 h or 120 h) on maturation of follicular oocytes and addition of caffeine (5 mM) and/or heparin (100 pg/ml) on sperm penetration and pro-nuclear formation were investigated. Spermatozoa recovered from the vasa deferentia of four mature males were diluted (5-fold) and frozen at - 80°C. The post-thawed and pooled spermatozoa were used for in vitro insemination. A higher (P < 0.05) proportion of the oocytes cultured for 120 h (34.2% of 260) progressed beyond the second metaphase stage than of the oocytes cultured for 96 h (26.0% of 262). For the matured oocytes, higher rates of penetration (P < 0.05) and pronuclear formation (P < 0.01) were obtained in the oocytes cultured for 120 h (55.1% and 40.4%) than in those cultured for 96 h (32.4 % and 20.6%). Addition of caffeine and heparin did not show a significant effect. In Experiment 2, follicular oocytes matured for 120 h and then inseminated were cultured to examine the subsequent development in two culture systems (with and without co-cultured cumulus cells). Of 448 inseminated oocytes, cleaved embryos (2–16 cells) were observed with (5.8%) and without (4.9%) co-cultured systems. No cleavage was observed in 54 ova without insemination. These results indicate that in vitro fertilization of minke whale in vitro matured follicular oocytes with cryopreserved spermatozoa is possible, yielding cleaved embryos.
When theory and practice meet: Avenues for entrepreneurship education in music conservatories

In the field of higher music education conservatories, and more specifically in the so-called ‘classical music’, the first steps towards research regarding entrepreneurship are being taken, although the main obstacles to overcome are still at a conceptual level (to define what is entrepreneurship in this field, what the profile of a musician entrepreneur is, what exactly is understood when we talk about an entrepreneurial identity referred to Western classical music) and on a referential level (research is scarce on the professional identity of classical musicians, on motivation that leads to professional success, on employability of a musician in the 21st century). At the same time, thought and analysis are lacking on how music education addresses entrepreneurial spirit and how conservatories for higher education in Western classical music could provide their students with the necessary capacities to become professional entrepreneurial musicians. This article aims to explore the state of entrepreneurship of classical musicians and analyse what challenges and barriers are found in particular in this subfield. In order to clarify the key concepts, the most relevant and recent literature in entrepreneurship education has been reviewed. Searching for avenues for entrepreneurship education in music conservatories, theory and practice have been merged by applying the literature findings to some practical considerations raised at the International Conference on Music Entrepreneurship recently held in The Hague, together with the personal experience in the specific context of higher music education conservatories.
Expression of p16 (INK4a), cytokeratin 19, and Ki-67 in canine laryngeal squamous cell carcinoma

Abstract The study aimed at morphological and immunohistochemical characteristics of laryngeal squamous cell carcinomas and their metastases in canine lymph nodes and lungs. Tissue sections were stained using classical technique with haematoxylin and eosin. In addition, immunohistochemical studies were performed with p16, cytokeratin, and Ki-67 antibodies. An expression of all examined antigens was detected in laryngeal tumours, while in tumour metastases only expression of p16 protein and cytokeratin was demonstrated. The results pointed to higher proliferative potential of the primary tumour than of their metastases.
An experimental assessment of the upper elevational limit of flowering plants in the western Himalayas

Transplant experiments are a useful tool both for determining species' ranges and understanding their cause, yet such experiments have seldom been performed in areas where plants reach extremely high elevations. We examined the position of the upper elevational limits of vascular plants in E Ladakh, India, by transplanting individuals of 14 subnival species from 5800-5850 m elevation to a control site at the same elevation, as well as to edaphically suitable sites at 5960 m (subnival belt with sparse plant cover), to 6030 m (the highest elevation reached by vascular plants in the area) and to 6160 m elevation (no vascular plants observed). Two years later, transplants of 13 species survived at the control elevation, whereas 5 species survived at 5960 m, 2 species (Waldbeimia tridactylites, Poa attenuata) at 6030 m, and none at 6160 m. The highest elevation at which transplanted flowering plants survived corresponds well to the observed elevational limit. Soil temperature data at the sites suggest that the growing season, defined as the period with mean daily soil temperature above zero, lasted nearly 3 months at 5960 m, ca 1.5 month at 6030 m, but <3 weeks at 6160 m, moreover interrupted at the highest elevation by several days with temperatures remaining below zero. The experiment confirmed the observed sharp limit of vegetation, set not by any physical barrier per se (e.g. not by the top of the massif), but instead by physiological constraints of the species. The result provides support for the assumptions of mid-domain effect models that domain limits are defined by shared organismal adaptations in relation to environmental gradients, in this case tolerance to freezing temperature.
Microbiological and serological monitoring in hooded crow (Corvus corone cornix) in the Region Lombardia, Italy

Abstract The health status of 276 hooded crows (Corvus corone cornix) from various provinces of Lombardy was monitored for three years. Bacteriological examination detected E. coli (76%), Campylobacter jejuni (17%), Salmonella typhimurium (11.6%), Yersinia spp. (6.5%), Clamydophila abortus and C. psittaci (2.6%); from six birds showing severe prostration Pasteurella multocida was isolated. Virological and serological tests were negative for Avian Influenza virus (AIV), West Nile virus (WNV) and only three samples were positive for Newcastle disease virus (NDV) but only at serology (titre 1:16).

This study consisted of 3 groups: the Pump It Up group, the Zig Zag Run game group, and the Shuttle Run game control group with a sample of each group of 10. The Agility Illionis Test was chosen as the agility test instrument. The exercise was done three days a week for four weeks. Anova test results showed that there was a significant effect of Pump It Up and Zig Zag Run exercises on agility with indigo p <0.05, and LSD test showed there were differences in Pump It Up with Ziz Zag Run, there were differences in Pump It Up and Zig Zag Run with indigo p <0.05. The conclusion of this research was that Pump It Up and Zig Zag Run exercises increase agility
Incubation feeding by male Scarlet Tanagers: a mate removal experiment

Incubation feeding, where males feed their mates, is a common behavior in birds and may improve female condition, nest attentiveness, and nesting success. We used behavioral observations and a temporary mate removal experiment to test the female nutrition hypothesis for incubation feeding by male Scarlet Tanagers (Piranga olivacea). All males (N = 20) were observed incubation feeding and fed females both at the nest ( ¯ × 1.36 trips/h) and away from the nest ( ¯ × 20.1 trips/h). Male feeding rate off-nest was negatively correlated with the duration of female foraging bouts and positively correlated with the total time females spent incubating per hour. Eggs were predated at seven of 19 (37%) nests, but nest survival during incubation was not related to either female incubation behavior or male feeding rate. During temporary removal experiments (N = 12), female Scarlet Tanagers remained on the nest significantly longer and did not have longer foraging bouts. An unexpected outcome of the removal experiments was a dramatic change in female vocal behavior. All 12 experimental females gave chik-burr calls during the male-removal experiments ( ¯ × bout length = 11.7 min), but during normal observation periods only six of 20 females at the incubation stage gave chik-burr calls ( ¯ × bout length = 0.7 min, N = 20). Our results suggest that female tanagers likely gain nutritional benefits from incubation feeding, but male feeding may not improve immediate reproductive success. Nine of 54 (17%) nestlings in five of 17 broods (29%) were extra-pair young (EPY), indicating that males could potentially benefit from incubation feeding via mate retention and fidelity as well as, or instead of, through immediate gains in reproductive success. Our study indicates that females benefit from incubation feeding and do not simply passively accept food from their mates, but instead may influence male feeding rates through direct (e.g., mate following and vocalizing) and indirect (the threat of mate abandonment or cuckoldry) means.
Why a strong work-life balance system is needed?

Purpose. This paper describes the concept of “strength of the work-life balance system” as a new and more advanced form of involvement in work-life issues, which lead to a stronger relationship with positive outcomes such as performance, commitment or satisfaction. Design/methodology/approach. From a theoretical point of view, and following Bowen and Ostroff (2004; 2016)’s framework of strength, all the features of a strong work-life balance system are described. We define the characteristics that allow the work-life balance system to create strong situations in which clear messages are sent to employees about what appropriate behavior is. Findings. Offering specific practices or specific types of support is not enough; a strong work-life balance system must also be in place. The strength of the system, which refers to the process, allows the firm to convey a consistent message about the content of the practices. Employees’ motivation, attitudes and behaviors towards work-life balance are highly dependent on how they interpret the signals from employers about the work-life balance system designed but also implemented. Practical implications. Future research and practitioners should pay more attention not only to design work life practices, but also to the implementation process in order not to fail in gaining all the positive outcomes related to work life balance, for employers and employees. Originality/value. This paper is the first step in the exploration of the importance of the implementation process of a work-life balance system, for a better contribution to organization positive outcomes.
