The Effects of a Divided-Attention Timed Stepping Accuracy Task on Balance, Strength, Endurance, and Functional Performance in Healthy Older Adults: A Pilot Study
Authors: Leach Susan J. , Maring Joyce R. , Costello Ellen
Published: January 2019

The aim of this study was to investigate whether a 6-week Divided-Attention Stepping Accuracy Task (DATSAT) intervention improved the primary outcome measure, maximal step length; other balance measures (Berg Balance scale and Timed Up and Go test); leg strength; endurance (6-min walk test); and functional tasks in 15 community-dwelling healthy older adults ( age: 71.5 years, female: 46.7%) compared with 15 community-dwelling healthy older adults in a Bike and Strength (B&S) program ( age: 73.8 years, female: 33.3%). Participants trained 3× per week, 30–60 min per session. Stepping-group differences were significant for all measures. B&S group improved in maximal step length (anterior and lateral), strength, and one functional task. Stepping group outperformed B&S group in Timed Up and Go and maximal step length posterior. B&S group outperformed stepping group in two strength measures. Exertion scores were lower for the stepping group. Overall, Divided-Attention Timed Stepping Accuracy Task training resulted in more within-group improvements and two between-group measures with less perceived effort and shorter intervention times.

Published: January 2019

Besides its known function as a transport protein for testosterone and other steroid hormones, sex hormone–binding globulin (SHBG) is a biomarker associated with many adverse health effects. The aim of this study was to investigate the association of physical activity with SHBG serum levels in older adults. The physical activity and SHBG values for 1,259 older adults (43.4% female; 56.6% male) with a mean age of 75.6 ± 6.5 years were included in the analysis. The average daily walking duration was 104.2 ± 40.4 (mean ± SD) min. A positive dose–response relationship of daily walking duration with quartiles of SHBG was seen after adjustment for age, sex, history of cardiovascular diseases, diabetes, smoking, γ-glutamyl transferase, and C-reactive protein (p for trend = .010). However, this relationship disappeared after adjustment for body mass index (p for trend = .977). Body mass index seems to be an important determinant of SHBG and a possible confounding factor in the relationship of physical activity and SHBG.
Can Learning Self-Regulatory Competencies Through a Guided Intervention Improve Coaches’ Burnout Symptoms and Well-Being?
Authors: McNeill Kylie , Durand-Bush Natalie , Lemyre Pierre-Nicolas
Published: January 2019

While coaches are considered at risk of experiencing burnout, there is an absence of intervention studies addressing this syndrome. The purpose of this qualitative study was to conduct a self-regulation intervention with five Canadian developmental (n = 2) and elite (n = 3) sport coaches (three men, two women) experiencing moderate to high levels of burnout and examine the perceived impact of this intervention on their self-regulation capacity and experiences of burnout and well-being. The content analysis of the coaches’ outtake interviews and five bi-weekly journals revealed that all five of them learned to self-regulate more effectively by developing various competencies (e.g., strategic planning for their well-being, self-monitoring) and strategies (e.g., task delegation, facilitative self-talk). Four of the coaches also perceived improvements in their symptoms of burnout and well-being. Sport psychology interventions individualized for coaches are a promising means for helping them manage burnout and enhance their overall functioning.
Realizing, Adapting, and Thriving in Career Transitions From Gymnastics to Contemporary Circus Arts
Authors: van Rens Fleur E.C.A. , Filho Edson
Published: January 2019

The purpose of this study was to explore the career transition experiences of elite gymnasts who became professional circus artists. Eight (inter)national level gymnasts who worked as circus artists were interviewed. Using a constructionist approach to thematic data analysis, we identified a three-phase career transition process. High levels of psychological resilience characteristics were required in the first, “realizing” phase (i.e., motivation, hard work, social support, and optimism). The second, “adapting” phase involved balancing context-specific demands which included general stress, a loss of competence, social adjustment, taking calculated risks, and physical recovery. The third, “thriving” phase involved experiences of freedom, personal development, and social connectedness. During the career transition, changes from an athletic to circus artist identity were experienced. Practitioners are encouraged to support the psychological resilience and experiences of autonomy among circus artists during their career transitions. This is expected to facilitate circus artists’ wellbeing, safety, and career longevity.
How Coaches Can Prevent and Address Alcohol Consumption Among Student-Athletes
Authors: Chow Graig M. , Bird Matthew D. , Soendergaard Stinne , Yang Yanyun
Published: January 2019

This manuscript seeks to offer insight about how coaches can better address drinking among collegiate student-athletes. Using a mixed-methods design, 519 NCAA coaches reported their attitudes and behaviors toward student-athlete drinking, and responded to open-ended questions about their perceived role, strategies, and challenges to addressing problems in this population. Three dimensions of coaches’ attitudes and behaviors toward student-athlete drinking emerged that were consistent regardless of the players’ or coach’s gender or division: Concerned Communication, Conditional Leniency, and Enforcement. Effective strategies identified by coaches included enforcement of policy, education about consequences of drinking, establishment of quality coach-athlete relationships, and management of athletes’ schedules. Coaches indicated the need to play a role in managing, educating, influencing, and supporting the student-athletes to prevent alcohol misuse. Coaches reported challenges regarding the culture of drinking on college campuses, individual differences (e.g., age) among student-athletes, acceptance and enforcement of the alcohol policy, lack of awareness about student-athletes’ activities, and identification of alcohol misuse.
Functional Outcomes and Psychological Benefits of Active Video Games in the Rehabilitation of Lateral Ankle Sprains: A Case Report
Authors: Arvinen-Barrow Monna , Maresh Nathan , Earl-Boehm Jennifer
Published: January 2019

Context:The use of active video games (AVG) as a treatment modality in the rehabilitation context is increasing. However, little is known about the functional outcomes and psychological benefits of such rehabilitation in college athletes with lateral ankle sprains (LASs).Objective:To examine functional outcomes and psychological benefits of AVG-aided rehabilitation program for LAS.Design:A mixed-methods, single-subject case series design.Setting:College athletic training clinic.Patients:Two female college soccer players who sustained LAS (grades I and II) during sport participation.Intervention:A 4-week balance training program. One patient completed balance exercises using AVG, whereas the other patient completed traditional balance exercises.Main Outcome Measures:Several validated instruments were used to evaluate different functional outcomes and psychological factors: balance (Balance Error Scoring System, Star Excursion Balance Test), rehabilitation adherence (Rehabilitation Adherence Measure for Athletic Training), foot and ankle function (Foot and Ankle Ability Measure), perceptions of pain (Visual Analog Scale for pain), perceived readiness to return to sport (Injury-Psychological Readiness to Return to Sport Scale), and mood (Brunel Mood Scale).Results:It appears that the balance training protocols (AVG and traditional balance exercises) were equally effective in restoring patient’s balance to functional levels. Despite very individualistic processes of rehabilitation, the participants’ perceived pain, perceived readiness to return to sport, and mood states were closely linked with objective and subjective functional measures of progress.Conclusions:Based on the results, AVG has the potential to provide more versatility into the static and dynamic postural control exercises typically used following acute LAS. Moreover, the current results support the existing psychological and biopsychosocial theoretical conceptualizations of athletes’ responses to injuries and rehabilitation process.
Can the Use of Unstable Surfaces and Instruction for Conscious Abdominal Contraction Increase the EMG Activity of the Periscapular Muscles During the Dynamic Push-Up?
Authors: de Araújo Rodrigo Cappato , Nascimento Vinícius Yan Santos , Torres Rafaela Joyce Barbosa , Trombini-Souza Francis , Behm David , Pitangui Ana Carolina Rodarti
Published: January 2019

Context: It is believed that conscious abdominal contraction (CAC) during exercise encourages greater periscapular activation through existing myofascial connections. On the other hand, it is postulated that the use of unstable surfaces would promote greater neuromuscular demand. Objective: To analyze the effect of CAC on periscapular muscle activity during push-up plus exercise on stable and unstable surfaces and to evaluate the correlation between electromyographic (EMG) activity of the serratus anterior (SA) and abdominal oblique muscles. Design: Repeated-measures design in a single group, pre–post CAC. Setting: Biomechanics laboratory. Participants: Twenty-three male volunteers without a history of lesions in the upper limbs participated in the study. Main Outcome Measures: Five repetitions of push-ups on stable and unstable surfaces were performed with and without instruction for CAC. The normalized amplitude of the EMG activity was obtained from the muscles of the upper, middle, and lower trapezius, SA upper (SA_5th) and lower (SA_7th) portions, external oblique (EO), and internal oblique. Results: CAC increased the activity of the EO, internal oblique, middle trapezius, and SA (P < .05) in both surfaces. The use of the unstable surface increased the EMG activity of the EO, SA_7th, and middle trapezius and decreased the EMG activity of the SA_5th. However, all changes observed in EMG signals were of low magnitude, with effect sizes lower than 0.45. There was a weak correlation between the EMG activity of the EO and SA_5th (r = .24) and a strong correlation between the EO and SA_7th (r = .70). Conclusion: The isolated use of CAC or unstable surface during push-up seems to present no practical relevance, but the combined use of these strategies may increase activation of the SA_7th and middle trapezius muscles.

Published: January 2019

The effect of high hydrostatic pressure on the relaxation of the electrical resistivity at room temperature of oxygen-nonstoichiometric [Formula: see text] (Re = Y, Ho) single crystals is investigated. The application of hydrostatic pressure has been revealed to significantly intensify the process of diffusion coalescence in the oxygen subsystem. At the same time, the intensity of the redistribution of labile oxygen is significantly changed when yttrium is replaced by holmium.
IMPACT OF FUTURE CLIMATE CHANGE (2020–2059) ON THE HYDROLOGICAL REGIME IN THE HEIHE RIVER BASIN IN SHAANXI PROVINCE, CHINA

Published: January 2019

Assessing the impacts of climate change on hydrological regime and associated social and economic activities (such as farming) is important for water resources management in any river basin. In this study, we used the popular Soil and Water Assessment Tool (SWAT) to evaluate the impacts of future climate change on the availability of water resources in the Heihe River basin located within Shaanxi Province, China, in terms of runoff and streamflow. The results show that over the next 40 years (starting in 2020 till 2059), changes in the averaged annual runoff ratio are approximately [Formula: see text]11.0%, [Formula: see text]6.4%, 7.2%, and 20.4% for each of the next four consecutive decades as compared to the baseline period (2010–2019). The predicted annual runoff demonstrates an increase trend after a reduction and may result in increased drought and flood risk in the Heihe River basin. To minimize or mitigate these impacts, various adaptation methods have been proposed for the study area, such as stopping irrigation, flood control operation; reasonable development and utilization of regional underground water sources should be implemented in Zhouzhi county and Huyi region in the lower reaches of Heihe River basin.
Purine Release, Metabolism, and Signaling in the Inflammatory Response
Authors: Linden Joel , Koch-Nolte Friedrich , Dahl Gerhard
Published: January 2019

ATP, NAD+, and nucleic acids are abundant purines that, in addition to having critical intracellular functions, have evolved extracellular roles as danger signals released in response to cell lysis, apoptosis, degranulation, or membrane pore formation. In general ATP and NAD+have excitatory and adenosine has anti-inflammatory effects on immune cells. This review focuses on recent advances in our understanding of purine release mechanisms, ectoenzymes that metabolize purines (CD38, CD39, CD73, ENPP1, and ENPP2/autotaxin), and signaling by key P2 purinergic receptors (P2X7, P2Y2, and P2Y12). In addition to metabolizing ATP or NAD+, some purinergic ectoenzymes metabolize other inflammatory modulators, notably lysophosphatidic acid and cyclic GMP-AMP (cGAMP). Also discussed are extracellular signaling effects of NAD+mediated by ADP-ribosylation, and epigenetic effects of intracellular adenosine mediated by modification of S-adenosylmethionine-dependent DNA methylation.

Published: January 2019

Deterioration of lung functions and degradation of elastin fibers with age are accelerated during chronic obstructive pulmonary disease (COPD). Excessive genesis of soluble elastin peptides (EP) is a key factor in the pathophysiology of COPD. We have previously demonstrated that 6-wk-old mice exhibited emphysematous structural changes associated with proinflammatory immune response after EP instillation. In this study, we investigated the consequences of aging on inflammatory, immune, and histological criteria associated with murine emphysema progression after EP exposure. Young (6 wk old) and elderly (15 mo old) C57BL/6J mice were endotracheally instilled with EP, and, at various time points after treatment, the inflammatory cell profiles from bronchoalveolar lavage fluids (BALF) and the T-lymphocyte phenotypes, at local and systemic levels, were analyzed by flow cytometry. Lungs were also prepared to allow morphological and histological analysis by confocal microscopy. Elderly mice exhibited an earlier development of pulmonary emphysema, characterized by an increase of the inflammatory and lymphocytic infiltrates, extracellular matrix breakdown, and airspace enlargement compared with young mice. This age-dependent parenchymal tissue remodeling was associated with an increase of the matrix metalloproteinase expressions and desmosine levels in BALF and/or sera of EP-treated mice. In addition, both the proportion of CD4+CD28−and CD8+CD28−T cells in the tissues of EP-treated mice and the interferon-γ levels in the EP-specific memory T-cell clones were significantly higher in elderly versus younger mice. This study demonstrates that aging accelerates emphysema development and that this effect is linked to increased EP production and their effects on inflammatory and immune response.

Published: January 2019

The purpose of this study was to characterize the growth and remodeling molecular signaling response in aged skeletal muscle following 1 mo of “resistance-type exercise” training. Male Fischer 344 × Brown Norway hybrid rats aged 3 (young) and 30 mo (old) underwent stretch-shortening contraction (SSC) loading 2 or 3 days/wk; muscles were removed 72 h posttraining. Young rats SSC loaded 3 (Y3x) or 2 days/wk (Y2x) adapted via increased work performance. Old rats SSC loaded 3 days/wk (O3x) maladapted via decreased negative work; however, old rats SSC loaded 2 days/wk (O2x) adapted through improved negative and positive work. Y3x, Y2x, and O2x, but not O3x, displayed hypertrophy via larger fiber area and myonuclear domains. Y3x, Y2x, and O2x differentially expressed 19, 30, and 8 phosphatidylinositol 3-kinase-Akt genes, respectively, whereas O3x only expressed 2. Bioinformatics analysis revealed that rats in the adapting groups presented growth and remodeling processes (i.e., increased protein synthesis), whereas O3x demonstrated inflammatory signaling. In conclusion, reducing SSC-loading frequency in aged rodents positively influences the molecular signaling microenvironment, promoting muscle adaptation.

NEW & NOTEWORTHY Decreasing resistance-type exercise training frequency in old rodents led to adaptation through enhancements in performance, fiber areas, and myonuclear domains. Modifying frequency influenced the molecular environment through improvements in phosphatidylinositol 3-kinase-Akt pathway-specific expression and bioinformatics indicating increased protein synthesis. Reducing training frequency may be appropriate in older individuals who respond unfavorably to higher frequencies (i.e., maladaptation); overall, modifying the parameters of the exercise prescription can affect the cellular environment, ultimately leading to adaptive or maladaptive outcomes.
A Novel Fog Computing Based Architecture to Improve the Performance in Content Delivery Networks
Authors: Alghamdi Fatimah , Mahfoudh Saoucene , Barnawi Ahmed
Published: January 2019

Along with the continuing evolution of the Internet and its applications, Content Delivery Networks (CDNs) have become a hot topic with both opportunities and challenges. CDNs were mainly proposed to solve content availability and download time issues by delivering content through edge cache servers deployed around the world. In our previous work, we presented a novel CDN architecture based on a Fog computing environment as a promising solution for real-time applications. In such architecture, we proposed to use a name-based routing protocol following the Information Centric Networking (ICN) approach, with a popularity-based caching strategy to guarantee overall delivery performance. To validate our design principle, we have implemented the proposed Fog-based CDN architecture with its major protocol components and evaluated its performance, as shown through this article. On the one hand, we have extended the Optimized Link-State Routing (OLSR) protocol to be content aware (CA-OLSR), i.e., so that it uses content names as routing labels. Then, we have integrated CA-OLSR with the popularity-based caching strategy, which caches only the most popular content (MPC). On the other hand, we have considered two similar architectures for conducting performance comparative studies. The first is pure Fog-based CDN implemented by the original OLSR (IP-based routing) protocol along with the default caching strategy. The second is a classical cloud-based CDN implemented by the original OLSR. Through extensive simulation experiments, we have shown that our Fog-based CDN architecture outperforms the other compared architectures. CA-OLSR achieves the highest packet delivery ratio (PDR) and the lowest delay for all simulated numbers of connected users. Furthermore, the MPC caching strategy shows higher cache hit rates with fewer numbers of caching operations compared to the existing default caching strategy, which caches all the pass-by content.

Published: January 2019

Rear-end collision crash is one of the most common accidents on the road. Accurate driving style recognition considering rear-end collision risk is crucial to design useful driver assistance systems and vehicle control systems. The purpose of this study is to develop a driving style recognition method based on vehicle trajectory data extracted from the surveillance video. First, three rear-end collision surrogates, Inversed Time to Collision (ITTC), Time-Headway (THW), and Modified Margin to Collision (MMTC), are selected to evaluate the collision risk level of vehicle trajectory for each driver. The driving style of each driver in training data is labelled based on their collision risk level using K-mean algorithm. Then, the driving style recognition model’s inputs are extracted from vehicle trajectory features, including acceleration, relative speed, and relative distance, using Discrete Fourier Transform (DFT), Discrete Wavelet Transform (DWT), and statistical method to facilitate the driving style recognition. Finally, Supporting Vector Machine (SVM) is applied to recognize driving style based on the labelled data. The performance of Random Forest (RF), K-Nearest Neighbor (KNN), and Multi-Layer Perceptron (MLP) is also compared with SVM. The results show that SVM overperforms others with 91.7% accuracy with DWT feature extraction method.

Published: January 2019

Aim: To evaluate the prevalence and clinical features of Fabry disease in patients with end-stage renal disease (ESRD) undergoing chronic hemodialysis. Methods: α-Galactosidase A activity was measured in the dried blood spots by tandem mass spectrometry in 5,572 dialysis patients (63.7% males). Diagnosis of Fabry disease was confirmed by sequencing of the GLA gene and by evaluating the globotriaosylsphingosine level in the dried blood spots. Results: Fabry disease was diagnosed in 20 (0.36%) patients at the median age of 43 years (28; 58). There were 19 males and 1 female. The prevalence of Fabry disease in dialysis patients was 0.53% in males and 0.05% in females. However, it was higher in males aged 30–49 years. Seventeen different GLA mutations were identified; 5 of them were novel. The median age at the initiation of hemodialysis was similar between patients with missense and nonsense mutations. Sixteen patients (80.0%) presented with typical symptoms of Fabry disease from childhood (neuropathic pain in 16, angiokeratoma in 7 and hypohidrosis/anhidrosis in 16). All patients had left ventricular hypertrophy, and 8 patients (40%) had a history of ischemic stroke. Two patients died (recurrent stroke in one and sudden cardiac death in another patient). Conclusions: Screening in at-risk patients remains the feasible approach to diagnose Fabry disease in patients with ESRD and their family members, given a low awareness of Fabry disease among the Russian nephrologists.
Long-Term Ventilation in Neuromuscular Patients: Review of Concerns, Beliefs, and Ethical Dilemmas
Authors: Crimi Claudia , Pierucci Paola , Carlucci Annalisa , Cortegiani Andrea , Gregoretti Cesare
Published: January 2019

Background: Noninvasive mechanical ventilation (NIV) is an effective treatment in patients with neuromuscular diseases (NMD) to improve symptoms, quality of life, and survival. Summary: NIV should be used early in the course of respiratory muscle involvement in NMD patients and its requirements may increase over time. Therefore, training on technical equipment at home and advice on problem solving are warranted. Remote monitoring of ventilator parameters using built-in ventilator software is recommended. Telemedicine may be helpful in reducing hospital admissions. Anticipatory planning and palliative care should be carried out to lessen the burden of care, to maintain or withdraw from NIV, and to guarantee the most respectful management in the last days of NMD patients’ life. Key Message: Long-term NIV is effective but challenging in NMD patients. Efforts should be made by health care providers in arranging a planned transition to home and end-of-life discussions for ventilator-assisted individuals and their families.

Authors: Dăescu Ecaterina , Enache Alexandra , Sztika Dorina , Zăhoi Delia Elena
Published: January 2019

Objective: A routine dissection of the cadaver of a 67-year-old man revealed a very rare morphological variant of the great cardiac vein (GCV). Presentation: The vein originated in the upper third of the anterior interventricular sulcus, crossed the anterior interventricular artery superficially, ran beneath the circumflex artery, crossed the transverse pericardial sinus, and drained directly into the superior vena cava. Conclusion: This variant of the GCV is interesting due to its rarity. It is important to know about it for procedures that require venous access such as coronary surgery requiring retrograde cardioplegia, surgical ablation of aberrant conducting pathways, pacemaker insertion, and valve surgery.

Prolactin-secreting tumors (prolactinomas) represent the most common pituitary tumor type, accounting for 47–66% of functional pituitary tumors. Prolactinomas are usually benign and controllable tumors as they express abundant levels of dopamine type 2 receptor (D2), and can be treated with dopaminergic drugs, effectively reducing prolactin levels and tumor volume. However, a proportion of prolactinomas exhibit aggressive features (including invasiveness, relevant growth despite adequate dopamine agonist treatment, and recurrence potential) and few may exhibit metastasizing potential (carcinomas). In this context, the clinical, pathological, and molecular definitions of malignant and aggressive prolactinomas remain to be clearly defined, as primary prolactin-secreting carcinomas are similar to aggressive adenomas until the presence of metastases is detected. Indeed, standard molecular and histological analyses do not reflect differences between carcinomas and adenomas at a first glance and have limitations in prediction of the aggressive progression of prolactinomas, wherein the causes underlying the aggressive behavior remain unknown. Herein we present a comprehensive, multidisciplinary review of the most relevant epidemiological, clinical, pathological, genetic, biochemical, and molecular aspects of aggressive and malignant prolactinomas.
Gelidium guimaraesiae sp. nov. (Gelidiaceae, Rhodophyta) from the Western Atlantic segregated from G. floridanum by morphological and molecular evidence
Authors: BRUNELLI BEATRIZ , MILSTEIN DANIELA , BOO SUNG M. , FUJII MUTUE T.
Published: January 2019

The Gelidium species are susceptible to a great phenotypic plasticity. In this genus, studies integrating morphological and molecular data have been increasingly used to define species. To date nine Gelidium species are reported along the Brazilian coast. Gelidium floridanum is the most frequently recorded species in Brazilian but it is also often confused with morphologically similar species, especially in the field or when reproductive structures are absent. In this study we analyzed specimens from Brazil previously identified as G. floridanum based on the morphological and molecular data (cox1 and rbcL DNA sequences). Newly collected specimens from Brazil showed a DNA sequence divergence from G. floridanum in the order of 1.0–1.4% for rbcL and 4.2% for cox1, enough to be considered a new species, here described as Gelidium guimaraesiae sp. nov.

Published: January 2019

The ephemeral and fragmented nature of plant communities in the desert region of Ica, Peru have contributed to the poor documentation of its flora. This study provides the first comprehensive checklist and analysis of the vascular plants and habitats of the region, based on over 1800 herbarium collections, site-specific vegetation surveys and monitoring (2001–2017). Here, we report 501 taxa belonging to 283 genera in 68 families, with an outstanding number of taxa (297) representing new records for the region; over 10% of the flora (52 taxa) is categorised as threatened (CR, EN, VU). Asteraceae is the largest family in the checklist, followed by Poaceae, Fabaceae and Solanaceae. The highest species richness is found in quebradas and huaycos (170 taxa), followed by lomas (137 taxa) and huertas (115). Of the lomas taxa, 28% are assessed nationally as threatened, and 95 taxa (68%) are endemic to Peru. Across all habitats five species are restricted to the Ica region (Cleistocactus clavispinus, Haageocereus icensis, Onoseris humboldtiana, Nolana willeana, Tecoma fulva subsp. guarume). Nolana willeana, not collected since 1956, was rediscovered in 2006. We provide insights into habitat and taxonomic delimitation of enigmatic species in the following genera: Bulnesia, Capparis, Eremocharis, Hoffmannseggia, Leptoglossis, Lomanthus Maytenus, Poissonia and Weberbauerella, among others. We support the reinstatement of Prosopis limensis as a valid species and provide information for its identification in the field. Analysis of Inga feuillei as an ancient domestication vital to agriculture, is provided, and we report an additional 127 cultivated species associated with traditional agriculture, assessing origins and conservation priority. We present climatic and geological observations for the region with spatial and ENSO-related research from data, plots and transects. A vegetation map and niche model are provided. Threatened lomas species are detailed to support conservation and policy. To aid identification we provide photographs of 155 plant species and all key habitats. The sustainable wellbeing of the Ica region depends on concerted collaboration to monitor, conserve and restore native plants wisely for the natural resources they provide to people and agriculture.

Two new species of Hippolyte from the Tropical Central and East Atlantic (Crustacea, Decapoda, Caridea)
Authors: FRANSEN CHARLES H.J.M. , DE GRAVE SAMMY
Published: January 2019

Two new species of the caridean shrimp genus Hippolyte Leach, 1814 [in Leach, 1813-14] are described from the Tropical Central and East Atlantic. Hippolyte cedrici sp. nov., from Príncipe and São Tomé, can be distinguished from both the related H. holthuisi Zariquey Álvarez, 1953 and H. varians Leach, 1814 on the basis of rostral dentition, as well as meristics of the ambulatory pereiopods. Hippolyte karenae sp. nov., from St. Helena, is morphologically similar to H. coerulescens (Fabricius, 1775) and H. obliquimanus Dana, 1852, by having a well-developed tooth on the outer angle of the first peduncular article of the antennula. It differs from these species, amongst other characters, primarily in the armature of the ambulatory dactyli. Specimens were collected from hydrozoan, antipatharian and alcyonarian cnidarians.
New European Lepidocyrtus Bourlet, 1839 (Collembola, Entomobryidae) with the first description of feeding-related dancing behaviour in Collembola
Authors: MATEOS EDUARDO , LUKIĆ MARKO
Published: January 2019

The study of a springtail population from Krka National Park (Croatia) has allowed us to describe the new species Lepidocyrtus chorus sp. nov. and its dance-like behaviour. This study represents the first record of peculiar dancing behaviour related to search for food and feeding among Collembola. The new species is molecularly and morphologically assigned to the European Lepidocyrtus lignorum-group. Sequences of COXII and EF-1α genes, chaetotaxy and behaviour clearly help to differentiate the new species from the other species in the group.
Upscale Impact of Mesoscale Convective Systems and Its Parameterization in an Idealized GCM for an MJO Analog above the Equator
Authors: Yang Qiu , Majda Andrew J. , Moncrieff Mitchell W.
Published: January 2019

The Madden–Julian oscillation (MJO) typically contains several superclusters and numerous embedded mesoscale convective systems (MCSs). It is hypothesized here that the poorly simulated MJOs in current coarse-resolution global climate models (GCMs) is related to the inadequate treatment of unresolved MCSs. So its parameterization should provide the missing collective effects of MCSs. However, a satisfactory understanding of the upscale impact of MCSs on the MJO is still lacking. A simple two-dimensional multicloud model is used as an idealized GCM with clear deficiencies. Eddy transfer of momentum and temperature by the MCSs, predicted by the mesoscale equatorial synoptic dynamics (MESD) model, is added to this idealized GCM. The upscale impact of westward-moving MCSs promotes eastward propagation of the MJO analog, consistent with the theoretical prediction of the MESD model. Furthermore, the upscale impact of upshear-moving MCSs significantly intensifies the westerly wind burst because of two-way feedback between easterly vertical shear and eddy momentum transfer with low-level eastward momentum forcing. Finally, a basic parameterization of the upscale impact of upshear-moving MCSs modulated by deep heating excess and vertical shear strength significantly improves key features of the MJO analog in the idealized GCM with clear deficiencies. A three-way interaction mechanism between the MJO analog, parameterized upscale impact of MCSs, and background vertical shear is identified.

Evaluation of Chinese precipitation extremes is conducted based on large ensemble projections of the present climate and 4-K-warmer climates derived from a high-resolution atmospheric general circulation model. The model reproduced the overall trend and magnitude of total precipitation and extreme precipitation events for China reasonably well, revealing that this dataset can represent localized precipitation extremes. Precipitation extremes are more frequent and more severe in future projections under 4-K-warmer climates than in the representative concentration pathway 8.5 (RCP8.5) scenario of phase 5 of the Coupled Model Intercomparison Project (CMIP5). Our results show that using a large-ensemble simulation can improve the ability to estimate with high precision both the precipitation mean and the precipitation extremes compared with small numbers of simulations, and the averaged maximum yearly precipitation will be likely to increase by approximately 18% under a +4-K future in southern China compared with the past. Finally, uncertainty evaluation in future precipitation projections indicates that the component caused by the difference in six ΔSST patterns is more important in southern China compared with the component due to the atmospheric internal variability. All these results could provide valuable insights in simulating and predicting precipitation extremes in China.
Centering at the Margins: Critical Community Resilience Praxis
Authors: Atallah Devin G. , Bacigalupe Gonzalo , Repetto Paula
Published: January 2019

Aims: This article aims to reframe resilience for use in community research and action in conditions of adversity marked by increasing natural disasters and by social inequities rooted in the coloniality of power, such as in Chile. Method: We review international resilience literature that explores responses to complex adversities, evaluating three “waves” of resilience research, including (1) “bouncing back,” which frames resilience as protecting functioning; (2) “bouncing forward,” understanding resilience as adaptation; and (3) what we are calling, the “centering at the margins” wave, which explicitly incorporates liberation psychology and decolonial, critical race theories to the study and promotion of resilience. Results: Building off “third wave” thinking, this article attempts to improve the social justice ethics within which research on resilience is completed by introducing a critical community resilience praxis. Conclusions: Critical community resilience praxis can aid the study of resilience by illuminating ways to avoid the reinforcement of social hierarchies and interlocking systems of oppression relevant to the work of disaster risk reduction investigators, psychologists, and differently positioned stakeholders engaged in resilience research and practice in complex settings internationally marked by histories of colonialism, consequences of climate change, and continual social inequities.
Institutional change and divergent economic resilience: Path development of two resource-depleted cities in China
Authors: Hu Xiaohui , Yang Chun
Published: January 2019

Existing literature on the economic resilience of cities has primarily focused on the study of capabilities and outcomes, while little has been conducted on the evolutionary processes. Drawing upon institutional change and path development concepts, this article develops an analytical framework that explains how different modes of institutional change shape path development processes in relation to economic resilience in cities. This article provides a comparative study on the divergent path development involving distinctive institutional change mechanisms in two Chinese mining cities both facing resource depletion since 2000, namely Zaozhuang in Shandong province and Fuxin in Liaoning province. It shows that Zaozhuang enables endogenously-based layering and conversion that leads to path renewal and creation with a more dynamic resilience engendering structural change, whereas Fuxin is trapped in exogenously-induced institutional thickening that results in path persistence and extension with a less dynamic resilience hindering economic renewal. The findings of this study advance the regional resilience literature by incorporating the role of agency, institutional change and path development in the context of China.
Patents and Plant Breeder's Rights over Plant Genetic Resources for Food and Agriculture
Authors: Lawson Charles
Published: January 2019

Recognising the importance of species diversity in conserving and exploiting plant genetic resources for food and agriculture, international and domestic arrangements have attempted over the decades in situ conservation, ex situ germplasm collections and germplasm exchange mechanisms. These initiatives established valuable resources for the development of new crop and forage plant varieties but there were no uniform or binding arrangements for conserving and accessing these resources. A more formal and uniform arrangement to both facilitate the conservation and exchange of some crop and forage plant genetic materials and share the benefits is now addressed in the International Treaty on Plant Genetic Resources for Food and Agriculture (‘PGRFA Treaty’). The Food and Agriculture Organization of the United Nations (‘FAO’) adopted the PGRFA Treaty in 2001, although it has not yet entered into force. A separate and distinct PGRFA Treaty was the culmination of the re-negotiation of the United Nations' International Undertaking on Plant Genetic Resources for Food and Agriculture recognising ‘the special nature of agricultural biodiversity, its distinctive features and problems needing distinctive solutions’.
‘All is Changed, Changed Utterly’? - The Causes and Consequences of New Zealand's Adoption of MMP
Authors: Geddis Andrew , Morris Caroline
Published: January 2019

New Zealand’s political landscape experienced a seismic shift in 1993, when the country replaced the First-Past-The-Post (FPTP) voting system it had inherited from its British colonial past with a new Mixed Member Proportional (MMP) voting system. The move had immediate and deep ramifications for a whole range of issues: the range of interests represented in Parliament; the way that governments are formed and function; how the country’s public sector agencies operate; the manner in which its electoral participants conduct their campaigns; and so on. Indeed, it is not too much of an exaggeration to say that every area of New Zealand’s public and political life was touched in some fashion by the general ‘systems change’ produced by the country’s decision to embrace MMP.5 These changes have effected shifts in what may be termed the ‘political culture’ of New Zealand; re-alignments in the relationships between various public and political institutions and bodies; as well as alterations to the formal legal rules that govern these institutions and bodies.
Protecting Consumer Privacy and Data Security: Regulatory Challenges and Potential Future Directions
Authors: Corones Stephen , Davis Juliet
Published: January 2019

This article considers the regulatory problems of online tracking behaviour, lack of consent to data collection, and the security of data collected with or without consent. Since the mid-1990s the United States Federal Trade Commission has been using its power under the United States consumer protection regime to regulate these problems. The Australian Competition and Consumer Commission (ACCC), on the other hand, has yet to bring civil or criminal proceedings for online privacy or data security breaches, which indicates a reluctance to employ the Australian Consumer Law (‘ACL’) in this field. Recent legislative action instead points to a greater application of the specifically targeted laws under the Privacy Act 1988 (Cth) (‘Privacy Act’), and the powers of the Office of the Australian Information Commissioner (OAIC), to protect consumer privacy and data security. This article contends that while specific legislation setting out, and publicly enforcing, businesses’ legal obligations with respect to online privacy and data protection is an appropriate regulatory response, the ACL's broad, general protections and public and/or private enforcement mechanisms also have a role to play in protecting consumer privacy and data security.
The Democratic Deficit of United States Federalism? Red State, Blue State, Purple?
Authors: Jackson Vicki C
Published: January 2019

Aspects of an entrenched constitution that were essential parts of founding compromises, and justified as necessary when a constitution was first adopted, may become less justifiable over time. Is this the case with respect to the structure of the United States Senate? The US Senate is hardwired in the Constitution to consist of an equal number of Senators from each state—the smallest of which currently has about 585,000 residents, and the largest of which has about 39.29 million. As this essay explains, over time, as population inequalities among states have grown larger, so too has the disproportionate voting power of smaller-population states in the national Senate. As a result of the ‘one-person, one-vote’ decisions of the 1960s that applied to both houses of state legislatures, each state legislature now is arguably more representative of its state population than the US Congress is of the US population. The ‘democratic deficit’ of the Senate, compared to state legislative bodies, also affects presidential (as compared to gubernatorial) elections. When founding compromises deeply entrenched in a constitution develop harder-to-justify consequences, should constitutional interpretation change responsively? Possible implications of the ‘democratic’ difference between the national and the state legislatures for US federalism doctrine are explored, especially with respect to the ‘pre-emption’ doctrine. Finally, the essay briefly considers the possibilities of federalism for addressing longer term issues of representation, polarisation and sustaining a single nation.
Federal and Territorial Courts

The decision of the High Court in Capital T.V. and Appliances Pty Ltd v. Falconer makes a further contribution to the step by step effort of the Court to develop a coherent doctrine with respect to the place of the Commonwealth Territories in the federal system. It goes some way towards answering the questions that arise with respect to the jurisdiction that may be exercised by territorial courts on the one hand, and on the other hand, the jurisdiction that may be exercised by federal courts, and State courts invested with federal jurisdiction, in respect of matters having a relationship with a Territory.

The matters decided were simply that the Supreme Court of the Australian Capital Territory is not a federal court, but is a territorial court established by virtue of the powers of the Parliament under section 122 of the Constitution, nor is it a court exercising federal jurisdiction. The Court did not find it necessary to decide whether the tenure of office of the judges of the Supreme Court met the requirements of section 72 of the Constitution with respect to federal courts. It held that, even assuming that those requirements were met, the Supreme Court was not a federal court. This conclusion was based on the intention of Parliament, as appearing from the words used to create the Court and the scope of the jurisdiction conferred on it. Further, it was held that the only courts “exercising federal jurisdiction”, apart from federal courts, are State courts invested with federal jurisdiction.
