IMPLEMENTASI TEORI FUNGSIONAL STRUKTURAL DALAM REGULASI PENYIARAN DIGITAL DI INDONESIA
Authors: Maulana Nur Malik 
Published: May 2020

Perkembangan teknologi penyiaran di dunia sudah beralih pada teknologi digital. Indonesia termasuk tertinggal dalam pelaksanaan penyiaran digital dikarenakan belum adanya payung hukum, dimana UU No.32/2002 tentang Penyiaran belum memuat aturan mengenai penyiaran digital. Menggunakan teori Fungsional Struktural, tulisan ini menganalisa bagaimana regulasi penyiaran digital seharusnya dibuat. Sebenarnya teknologi digital merupakan solusi yang tepat dalam mengatasi masalah keterbatasan frekuensi pada penyiaran analog, akan tetapi melimpahnya frekuensi digital ini justru menjadi potensi konflik. Hingga sekarang, pembahasan regulasi penyiaran digital masih berlangsung sengit terkait model multipleksing yang akan digunakan. Untuk menghindari terjadinya konflik di sistem sosial, single multipleksing merupakan model paling tepat, yaitu pemerintah menjadi operator penyelenggara multipleksing penyiaran digital mengingat frekuensi merupakan ranah publik, dan supaya terciptanya keteraturan penyiaran di Indonesia.Â Â The worldâ€™s broadcasting technology has been shifting to digital technology. In Indonesia, digital broadcasting implementation is, in fact, still left behind compared to other countries as it has no relevant regulations. Law Number 32/2002 about Broadcasting does not contain regulations related to digital broadcasting. By using Structural Functional approach, this study analyzes how digital broadcasting regulations should be made. Digital technology is a proper solution to the limited frequency problems of analog broadcasting. However, the abundance of digital frequency is also a potential conflict. Until now, discussions on the regulation of digital broadcasting are still occurring fiercely, especially on the multiplexing model to be used. To avoid conflicts in the social system, single multiplexing is the most proper model, in which the government becomes the operator of digital multiplexing-broadcasting implementation, considering the fact that frequency is a public belonging. This can also embody broadcast regularity in Indonesia.

Evaluation of the Research Protocol by Ethical Committee
Authors: Santos Paulo , Teixeira Pedro , Beça Helena , Hespanhol Alberto 
Published: May 2020

Nowadays, the submission of a research project to an ethical committee and its approval is mandatory. However, researchers often overlook this obligation, because they are too engaged in the design and the process of construction of the study, because of the common tight deadlines, and many times because some devaluation of the role of the committee. Based on our experience of 10 years working in an ethical committee, we propose a way to get close researchers and evaluators, respecting their own aims but bringing them together as partners in the investigation process, protecting patients’ values, at the same time that makes it possible to implement strategies to answer to the research question and to create useful knowledge. Our aim is to smoothen the way researchers look to the ethical committee and, at the same time, to make them understand what really is at stake. Ethics should be a commitment for all and not an obligation.
Replacement of Procambarus acutissimus (Girard) by non-indigenous Procambarus clarkii (Girard) in a disturbed wetland

Abstract
Of the nearly 600 crayfish species worldwide, more than half are native to North America. The southeastern USA is the epicenter of global crayfish species richness. There is concern about the conservation status of many crayfish species and the viability of their populations. Procambarus acutissimus is a surface dwelling crayfish that is native in Mississippi and Alabama and has isolated populations in west Georgia. Its limited distribution in Georgia prompted this re-assessment of a previously surveyed population in a wetland complex near Columbus, Georgia. To assess the population status of P. acutissimus, we used baited Gee minnow traps to survey crayfish in 2014 following similar protocols used in a 1994 survey. Catches from the littoral zone of a borrow pit lake shifted from only P. acutissimus in 1994 to only Procambarus clarkii, a non-indigenous, invasive species in 2014. Trapping in 2014 documented P. acutissimus in only one of five isolated wetland depressions sampled. Procambarus clarkii appears to be replacing P. acutissimus in this wetland complex. Our results suggest that P. clarkii may displace other crayfish, particularly those that share its affinity for wetland habitats.
Re-description of the Orbost spiny crayfish, Euastacus diversus Riek 1969 (Decapoda: Parastacidae), in eastern Victoria, Australia

Published: May 2020

Abstract
We present a thorough redescription of the endangered freshwater crayfish Euastacus diversus Riek, based on morphological and genetic analyses of newly collected material from eastern Victoria, Australia. The species displays a remarkably diverse morphology, particularly regarding the two key features previously used in its diagnosis: spination of the antennal squame and thorax. Genetic variation is also evident between populations, although this does not correlate with morphological variation. The distribution of the species is extended to 19 sites in the Brodribb, Yalmy, Rodger and Bonang River drainages at elevations ranging from 350 – 950 m a.s.l., with an overall Extent of Occurrence of 465 km2. To accommodate the revised taxonomy of this species, and to facilitate conservation and management efforts, we provide a key to this and similar species in Victoria.
Groundwater chemistry and soils have limited influence on the habitat-scale distribution of Cambarus harti Hobbs
Authors: Gilmer Jess H. , Keller Troy 
Published: May 2020

Abstract
Primary burrowing crayfish constitute 32% of crayfish considered imperiled, yet little is known about their autecology. To advance our knowledge about burrowing crayfish, groundwater chemistry and soils were assessed at sites containing the state-listed, endangered Cambarus harti Hobbs. Water chemistry was collected and analyzed every one to four weeks from January 2014 – August 2014 from wells (< 2 m deep) at four sites in Meriwether County (GA). Water samples were collected from wells near active burrows, wells without burrows, and burrows showing activity. To assess crayfish soil preferences, three soil cores were collected within ten meters of each well and dry sieved to determine percent sand and silt/clay. Water from wells (with/without crayfish) and burrows showed no differences in potassium, iron, manganese, and silica concentrations. Burrow water showed elevated chloride concentrations. Soils were sand-rich and contained only minor amounts of silt/clay. Soils differed slightly among sites but showed no difference between locations with and without burrows. Thus, bedrock and soils appear to be relatively homogeneous over the spatial scales studied. It is unclear if crayfish activity elevates chloride concentrations in burrows. These results corroborate previous research suggesting groundwater chemistry and soil texture are not the exclusive environmental factors controlling the distribution of primary burrowing crayfish.
Site specific assessments of burrow- and lentic-dwelling crayfish communities: A proposed sampling design
Authors: Taylor Christopher A. , Engelbert Bryan S. , DiStefano Robert J. 
Published: May 2020

AbstractWe conducted a study to investigate methods to assess crayfish populations typically found in low gradient, lentic, floodplain habitats in Missouri. We used a random site selection process that allowed us to capture all known species from this region of Missouri. We compared two sampling methods for primary burrowing crayfishes at our sampling sites: hook-and-line capture technique and burrow excavation. Adjacent standing water habitats at sites were also sampled using a timed search method. Hook-and-line capture success was substantially less than reported in the literature (0.7% versus 80%), while burrow excavation was higher than reported (64% versus 40.7%). We successfully captured six crayfish species using burrow excavation, whereas lentic timed search sampling captured nine species in adjacent standing waters at our sampling sites. Our results suggest that additional efforts sampling lentic habitats rather than additional time searching for and excavating burrows is more likely to capture total community richness. We found a seasonal influence on burrow occupancy surveys, as Julian day was positively correlated to finding active crayfish burrows. Crayfish capture in standing water was positively affected by soil temperature, and negatively correlated to Julian day.
Utilization of pit telemetry to assess microhabitat affinities of stream-dwelling female crayfish during reproductive seclusion
Authors: Black Tyler R. , Mattingly Hayden T. , Smith David D. 
Published: May 2020

Abstract
Stream habitat-use of female crayfish during brooding of eggs and hatchlings is a poorly studied aspect of crayfish life history and ecology. Our goal was to use passive integrated transponder (PIT) technology to describe diurnal habitat-use patterns of females of two crayfish species during reproductive seclusion. PIT tags were externally attached to female Cambarus friaufi in Pine Creek, Tennessee, USA and Orconectes meeki meeki in Rock Creek, Missouri, USA. Crayfish were tracked with a portable detector and habitatuse was assessed in 2008 for C. friaufi and 2009 for O. m. meeki. PIT tags proved to be a highly effective tool for relocating crayfish, with = 85% of tagged individuals located at least once. Substrate roughness was identified as the most important variable for both species during brooding, followed by additional substrate-related variables, water velocity, and water depth. Cambarus friaufi, however, was more of a generalist and used microhabitat variables in close proportion to availability, whereas O. m. meeki showed more specialized use of brooding habitat variables. Our results suggest that female crayfish reproductive seclusion is closely linked to sufficiently heterogeneous substrate. Reductions in substrate quality could potentially alter crayfish reproductive capacity, thus impacting biodiversity and productivity of streams.
Crayfish fauna of the Maksimir Lakes in the urban area of Zagreb
Authors: Njegovan Vanja , Orešković Mislav , Hudina Sandra , Maguire Ivana 
Published: May 2020

Abstract
Due to the increasing anthropogenic pressures and the introduction of invasive alien species, indigenous crayfish species are rarely found in the urban areas of big cities. The aim of this research was to study, for the first time, presence and distribution of freshwater crayfish in artificial lakes of the Maksimir Park, located in the centre of Zagreb, the capital of Croatia. Additionally, the goal was to estimate population size and structure, and analyse morphometric characteristics, the proportion of injuries and crayfish body condition. In 4 out of 5 lakes within the park, two crayfish species, Astacus astacus and Astacus leptodactylus, were recorded with no overlap in their distribution. Each species was established in two lakes in relatively abundant populations. Differences in body condition, sex ratio and proportion of injuries were recorded between species. Recorded differences are most likely the result of different trapping techniques applied, predation of alien invasive species of turtles and intraspecific competition. Obtained results will serve as a baseline for further research and monitoring of the crayfish fauna in the Maksimir lakes.
Chronic crayfish plague infection and eroded swimmeret syndrome in Lake Saimaa (Finland) signal crayfish
Authors: Jussila Japo , Tiitinen Vese , Edsman Lennart 
Published: May 2020

Abstract
We present data and results from a 9-year survey (2009 – 2017) of the Lake Saimaa signal crayfish population in Finland. This population has a history of chronic infection with Aphanomyces astaci. It has now been discovered that female signal crayfish from Lake Saimaa suffer from various stages of eroded swimmeret syndrome (ESS), and male crayfish also show symptoms of ESS-like trauma (i.e., eroded swimmerets and gonopods). Our data demonstrates the prevalence of A. astaci infection, with gross symptoms prevailing throughout the duration of the entire 2009 – 2017 survey, and that prevalence of ESS among female signal crayfish is correlated with the prevalence of A. astaci infection in the population. The data shows that an increasing proportion of female crayfish suffer from ESS, and have regenerated swimmerets, however, our observations indicate that partially regenerated swimmerets do not fully function during egg hatching. Based on data and observations during the survey, we speculate that low production levels, as indicated by the low catch per unit effort (CPUE), within the Lake Saimaa signal crayfish population could be related to both high A. astaci infection levels and ESS prevalence among females. The former could be causing increasing mortality among adult crayfish and the latter could be lowering Lake Saimaa signal crayfish reproductive output.

Published: May 2020

Moyamoya disease (MMD) is a progressive stenosis at the terminal portion of internal carotid artery and frequently occurs in East Asian countries. The etiology of MMD is still largely unknown. We performed a case-control design with whole-exome sequencing analysis on 31 sporadic MMD patients and 10 normal controls with matched age and gender. Patients clinically diagnosed with MMD was determined by digital subtraction angiography (DSA). Twelve predisposing mutations on seven genes associated with the sporadic MMD patients of Chinese ancestry (CCER2, HLA-DRB1, NSD-1, PDGFRB, PHACTR1, POGLUT1, and RNF213) were identified, of which eight single nucleotide variants (SNVs) were deleterious with CADD PHRED scaled score > 15. Sanger sequencing of nine cases with disease progression and 22 stable MMD cases validated that SNV (c.13185159G>T, p.V265L) on PHACTR1 was highly associated with the disease progression of MMD. Finally, we knocked down the expression of PHACTR1 by transfection with siRNA and measured the cell survival of human coronary artery endothelial cell (HCAEC) cells. PHACTR1 silence reduced the cell survival of HCAEC cells under serum starvation cultural condition. Together, these data identify novel predisposing mutations associated with MMD and reveal a requirement for PHACTR1 in mediating cell survival of endothelial cells.

Published: May 2020

Radiation components have distinct effects on photosynthesis. In the desert steppe ecosystem, the influence of diffuse radiation on carbon fixation has not been thoroughly explored. We examined this diffusion and its effect on ecosystem productivity was examined during the growing season from 2014 to 2015 on the basis of eddy covariance measurements of CO2 exchange in a desert steppe ecosystem in northwest China. Our results indicated that the gross ecosystem production (GEP) and diffuse photosynthetically active radiation (PARdif) peaked when the clearness index (CI) was around 0.5. The maximum canopy photosynthesis (Pmax) under cloudy skies (CI < 0.7) was 23.7% greater than under clear skies (CI ≥ 0.7). When the skies became cloudy in the desert steppe ecosystem, PARdif had a greater effect on GEP. Additionally, lower vapor pressure deficits (VPD ≤ 1 kPa), lower air temperatures (Ta ≤ 20 °C), and non-stressed water conditions (REW ≥ 0.4) were more conducive for enhanced ecosystem photosynthesis under cloudy skies than under clear skies. This may be due to the comprehensive effects of VPD and Ta on stomatal conductance. We concluded that cloudiness can influence diffuse radiation components and that diffuse radiation can increase the ecosystem production of desert steppe ecosystems in northwest China.

Published: May 2020

Abstract

Objective
To examine whether the cross-sectional association of leisure-time physical activity and walking during commuting to work with depressive symptoms depends on the level of work-related physical activity among Japanese workers.

Methods
Participants were 2024 workers aged 19-69 years in two manufacturing companies in Japan. Leisure-time physical activity and walking during commuting to work were ascertained via a self-administered questionnaire. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression (CES-D) scale. The odds ratio (OR) of depressive symptoms (CES-D score ≥16) was estimated by using multiple logistic regression with adjustment for covariates.

Results
Leisure-time physical activity was inversely associated with depressive symptoms; multivariable-adjusted ORs (95% confidence intervals) of having depressive symptoms for leisure-time physical activity were 1.00 (reference), 0.85 (0.64, 1.12), 0.69 (0.51, 0.94), and 0.59 (0.44, 0.80) for 0, &gt;0 to &lt;3.0, 3.0 to &lt;10.0, and ≥10.0 MET-h/wk, respectively (P for trend &lt;.001). This inverse trend for leisure-time physical activity was clearer among individuals who had low physical activity at workplace (less than 7.0 MET-h/d). For walking to work, such an inverse association was not observed.

Conclusion
Leisure-time physical activity was associated with fewer depressive symptoms, especially in workers with low work-related physical activity.

AbstractObjectiveA major challenge in the care of preterm infants is the early identification of compromised neurological development. While several measures are routinely used to track anatomical growth, there is a striking lack of reliable and objective tools for tracking maturation of early brain function; a cornerstone of lifelong neurological health. We present a cot‐side method for measuring the functional maturity of the newborn brain based on routinely available neurological monitoring with electroencephalography (EEG).MethodsWe used a dataset of 177 EEG recordings from 65 preterm infants to train a multivariable prediction of functional brain age (FBA) from EEG. The FBA was validated on an independent set of 99 EEG recordings from 42 preterm infants. The difference between FBA and postmenstrual age (PMA) was evaluated as a predictor for neurodevelopmental outcome.ResultsThe FBA correlated strongly with the PMA of an infant, with a median prediction error of less than 1 week. Moreover, individual babies follow well‐defined individual trajectories. The accuracy of the FBA applied to the validation set was statistically equivalent to the training set accuracy. In a subgroup of infants with repeated EEG recordings, a persistently negative predicted age difference was associated with poor neurodevelopmental outcome.InterpretationThe FBA enables the tracking of functional neurodevelopment in preterm infants. This establishes proof of principle for growth charts for brain function, a new tool to assist clinical management and identify infants who will benefit most from early intervention.
