Media Sosial Dan Kebijakan Kapolri Mengenai ”Hate Speech” (Ujaran Kebencian)
Authors: Kusuma Satria , P. Lubis Djuara
Published: July 2020

The developments of information technologies affect the life of democracy in Indonesia. Information technology such as social media has caused social change. Social media should be a public space to establish relations and public information centers. The user submits a message to create a closer ties with the community and convey information about social problems. The public get information faster from social media rather than print media, radio and television. But there are some people who spread false news (hoaxes) or even attack the other party through hate speech. Such actions lead to defamation toward certain people then lead public opinion to worsen the socio-political situation, causing a split. The insult to the President by a citizen through a message on social media which continues to the proceedings reminds us to be more concerned about the ethical consideration of communication in public spaces. This issue should be a shared responsibility between the organizers and users of social media in order to maintain a cultured communication behavior and ethical understanding. The policy from the head of Indonesian Police regarding hate speech in social media is the firm stance of the government against violators who deliberately spread messages of hate, violate the values, norms, manners and ethics. The act of spreading the message of hate speech is against the law. Hate speech message ruins the conduciveness of social and political situation. This kind of violation could threaten the mentality of younger generations as users of social media in creating a civilized communication in Indonesia.Keywords: hate speech policy, messages of hate, and social media.

In case of oil and natural gas production, a restricted zone within 500-meter-wide around offshore platform was established. The restricted zone was established to protect all activities in the sea, including fishing. Socialization on law, safety, and security, and the existence of oil and gas operational facility platform has been held. Yet, it hasn’t stopped the fishers’ effort to do fishing in the restricted zone. Therefore, this study tries to analyze communication model in the socialization and components that affect communication as well as correlation among the factors that influence the effectiveness of communication and fishers' obedience toward prohibition of entering the restricted zone. The study was conducted in one of the coastal villages in Karawang Regency, West Java. Data were collected by using questionnaire, which was supported by conducting qualitative method. The data, which were analyzed by rank Spearman Correlation Test. Results showed that communication model on socialization is not a convergent model but a linear and interactional model. There was a difference between a facilitator of socialization and fishing communities in terms of education level, social class, and language that becomes an obstacle for fishers to communicate. The message materials have not been complete yet, and there is no emotional and fear approachesin the message content of socialization. The use of radio as a communication channel has been ineffective because most fishers do not have a radio. Experience as fishers is significantly related to the fishers’ obedience and their view is very significant to their obedience. Meanwhile, the age, educational level, use of fishing tools, attendance at faceto-face socialization, exposure on advertising spots in radio and posters at Fish Auction Site (TPI), and the frequency of communication among the fishers are not significantly related to fishers’ obedience toward the prohibition of entering the restricted zone.Keywords: socialization, restricted zone, and fishers’ obedience

HBIM, 3D drawing and virtual reality for archaeological sites and ancient ruins
Authors: Banfi Fabrizio
Published: July 2020

Data collection, documentation and analysis of the traces of ancient ruins and archaeological sites represent an inestimable value to be handed down to future generations. Thanks to the development of new technologies in the field of computer graphics, Building Information Modelling (BIM), Virtual Reality (VR) and three-dimensional (3D) digital survey, this research proposes new levels of interactivity between users and virtual environments capable of communicating the tangible and intangible values of remains of ancient ruins. In this particular field of development, 3D drawing and digital modelling are based on the application of new Scan-to-HBIM-to-VR specifications capable of transforming simple points (point clouds) into mathematical models and digital information. Thanks to the direct application of novel grades of generation (GOG) and accuracy (GOA) it has been possible to go beyond the creation of complex models for heritage BIM (HBIM) and explore the creation of informative 3D representation composed by sub-elements (granular HBIM objects) characterized by a further level of knowledge. The value of measurement, 3D drawing and digital modelling have been investigated from the scientific point of view and oriented to the generation of a holistic model able to relate both with architects, engineers, and surveyors but also with archaeologists, restorers and virtual tourists.

Highlights:

The concept of ‘granular HBIM objects’ is introduced to show the unexpressed potential of the scan-to-BIM process for different types of data analyses and uses.

Sustainable development of VR projects for archaeological sites is proposed, allowing users to discover the hidden historical values with new levels of interactivity and information.

HBIM and VR projects have been improved through the integration of laser scanning, digital photogrammetry (terrestrial and UAV) and advanced modelling techniques.

Authors: Maneeri Akashlal , Nair Pratibha P , Nair Devi R
Published: July 2020

Background:

Hemiplegia is the paralysis/weakness of either side of the body with varying levels of loss of function. Stroke is one among the main causes of hemiplegia. According to Ayurveda, the symptomatic presentation of Pakshaghata resembles hemiplegia. Although different types of time-tested treatment protocols are being followed as per the disease severity or stage, many a time, a common treatment strategy, reliable data regarding a standardized treatment protocol, the cost-effectiveness, or adverse effects of the various treatment protocols are lacking. Hence, a systematic review is planned in this regard. This article comprehensively details the protocol adopted for the planned systematic review.

Objectives:

The manuscript reports the study protocol of a proposed systematic review with the prime objective of analyzing the published clinical data in view of safety and effectiveness of Ayurvedic treatment protocols in hemiplegia vis-à-vis Pakshaghata, qualitative review, and meta-analysis of the same.

Materials and methods:

The study shall be carried out by screening the published data and the gray literature available from famous search engines, namely, PubMed, Cochrane Library, AYUSH Research Portal, DHARA, Google Scholar, web page—Ancient Science of Life, Online clinical trials registers, Shodhganga@INFLIBNET. Papers on Ayurvedic management of hemiplegia/Pakshaghata will be screened for data analysis. Full articles of potentially eligible trials shall be obtained and independently evaluated for inclusion in the review based on the types of participants (inclusion criteria). Data extraction forms for individual study shall be prepared, which include methods, participant characteristics, interventions, and outcomes. Data extracted shall be systematically analyzed and presented using appropriate software.

Discussion:

The study outcome shall be disseminated in public domain. The data will reveal the benefits and adverse effects of Ayurvedic treatment in hemiplegia. This may help the stakeholders for drug/therapy selection, dose fixation, and framing future research.

Authors: C Thejaswini , GV Ramana , Sahoo Srinibash , Kumar Gupta Hemant
Published: July 2020

Introduction:

Anxiety disorder is one of the psychosomatic disorders characterized by persistent and irrational fear, anxiety, or avoidance of social or performance situations. Ayurveda incorporates different types of regimen, both therapeutic and non-therapeutic, in the management of psychiatric disorders. Till date, no systematic review of the evidence has been conducted focused on the safety and efficacy of Ayurvedic interventions in anxiety disorders. The current systematic review aims to generate evidence regarding the safety and efficacy of the Ayurveda interventions in the treatment of anxiety disorders through analysis of available data on clinical trials.

Materials and methods:

The relevant full papers and abstracts will be sought from electronic databases such as PubMed, the Cochrane Library, DHARA, AYUSH Research Portal, CTRI, and Google Scholar. Randomized controlled trials (RCTs), non-randomized controlled trials (NRCTs), quasi- randomized controlled trials (QRCTs), controlled clinical trials (CCTs), randomized/non-randomized placebo-controlled trials, controlled before- and-after studies (CBA), before-and-after comparisons, parallel arm comparative trials, and multiarm clinical trials will be included. Study selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and the methodological appraisal of the studies will be assessed by the Cochrane risk-of-bias tool as well as Jadad Scale for RCTs and risk-of-bias in non-randomized Studies tool for NRCTs. Primary outcomes will include measures related with response to the treatment and any serious adverse events. There will be no language restrictions on the data sought and searches run on research studies published from January 1980 to till date will be eligible for inclusion. The selection of the research studies, data abstraction, and validation of the studies will be performed independently; in case of disparity or other issues regarding the suitability of study for inclusion, the opinion of the third person will be sought for consensus. A meta-analysis will be conducted and effect sizes will be generated using Hedges'g score for both fixed and random effect models, only if sufficient data are available.

Ethics and dissemination:

As this will be a systematic review, which does not involve human beings, there will be no requirement for ethical approval. Findings will be disseminated widely through peer-reviewed publication and through conferences or symposia.

Abstract. We present a novel and compact design of a constant-pressure inlet (CPI) developed for use in airborne aerosol mass spectrometry. In particular, the inlet system is optimized for aerodynamic lenses commonly used in aerosol mass spectrometers, in which efficient focusing of aerosol particles into a vacuum chamber requires a precisely controlled lens pressure, typically of a few hectopascals. The CPI device can also be used in condensation particle counters (CPCs), cloud condensation nucleus counters (CCNCs), and gas-phase sampling instruments across a wide range of altitudes and inlet pressures. The constant pressure is achieved by changing the inner diameter of a properly scaled O-ring that acts as a critical orifice. The CPI control keeps air pressure and thereby mass flow rate (≈0.1 L min−1) upstream of an aerodynamic lens constant, deviating at most by only ±2 % from a preset value. In our setup, a pressure sensor downstream of the O-ring maintains control of the pinch mechanism via a feedback loop and setpoint conditions are reached within seconds. The device was implemented in a few instruments, which were successfully operated on different research aircraft covering a wide range of ambient pressures, from sea level up to about 55 hPa. Details of operation and the quality of aerosol particle transmission were evaluated by laboratory experiments and in-flight data with a single-particle mass spectrometer.
AIMERG: a new Asian precipitation dataset (0.1°/half-hourly, 2000–2015) by calibrating the GPM-era IMERG at a daily scale using APHRODITE

Published: July 2020

Abstract. Precipitation estimates with fine quality and spatio-temporal resolutions
play significant roles in understanding the global and regional cycles of
water, carbon, and energy. Satellite-based precipitation products are capable
of detecting spatial patterns and temporal variations of precipitation at
fine resolutions, which is particularly useful over poorly gauged regions.
However, satellite-based precipitation products are the indirect estimates
of precipitation, inherently containing regional and seasonal systematic
biases and random errors. In this study, focusing on the potential drawbacks
in generating Integrated Multi-satellitE Retrievals for Global Precipitation
Measurement (IMERG) and its recently updated retrospective IMERG in the
Tropical Rainfall Measuring Mission (TRMM) era (finished in July 2019),
which were only calibrated at a monthly scale using ground observations,
Global Precipitation Climatology Centre (GPCC, 1.0∘/monthly), we
aim to propose a new calibration algorithm for IMERG at a daily scale and to
provide a new AIMERG precipitation dataset (0.1∘/half-hourly,
2000–2015, Asia) with better quality, calibrated by Asian Precipitation – Highly Resolved Observational Data Integration Towards Evaluation of Water Resources (APHRODITE, 0.25∘/daily) at the daily scale for the Asian applications. The main
conclusions include but are not limited to the following: (1) the proposed daily calibration
algorithm (Daily Spatio-Temporal Disaggregation Calibration Algorithm,
DSTDCA) is effective in considering the advantages from both satellite-based
precipitation estimates and the ground observations; (2) AIMERG performs
better than IMERG at different spatio-temporal scales, in terms of both
systematic biases and random errors, over mainland China; and (3) APHRODITE demonstrates significant advantages compared to GPCC in calibrating IMERG, especially over mountainous regions with complex terrain, e.g.
the Tibetan Plateau. Additionally, results of this study suggest that it is
a promising and applicable daily calibration algorithm for GPM in generating
the future IMERG in either an operational scheme or a retrospective manner. The
AIMERG data are freely accessible at https://doi.org/10.5281/zenodo.3609352 (for the period from 2000 to 2008)
(Ma et al., 2020a) and https://doi.org/10.5281/zenodo.3609507
(for the period from 2009 to 2015) (Ma et al., 2020b). Highlights. A new effective daily calibration approach, DSTDCA, for improving the GPM-era IMERG is provided. New AIMERG precipitation data (0.1∘/half-hourly, 2000–2015,
Asia) are provided. Bias of AIMERG is significantly improved compared with that of IMERG. APHRODITE is more suitable than GPCC in anchoring IMERG over Asia.
Surrogate-assisted Bayesian inversion for landscape and basin evolution models
Authors: Chandra Rohitash , Azam Danial , Kapoor Arpit , Müller R. Dietmar
Published: July 2020

Abstract. The complex and computationally expensive nature of landscape evolution models poses significant challenges to the inference and optimization of unknown model parameters. Bayesian inference provides a methodology for estimation and uncertainty quantification of unknown model parameters. In our previous work, we developed parallel tempering Bayeslands as a framework for parameter estimation and uncertainty quantification for the Badlands landscape evolution model. Parallel tempering Bayeslands features high-performance computing that can feature dozens of processing cores running in parallel to enhance computational efficiency. Nevertheless, the procedure remains computationally challenging since thousands of samples need to be drawn and evaluated. In large-scale landscape evolution problems, a single model evaluation can take from several minutes to hours and in some instances, even days or weeks. Surrogate-assisted optimization has been used for several computationally expensive engineering problems which motivate its use in optimization and inference of complex geoscientific models. The use of surrogate models can speed up parallel tempering Bayeslands by developing computationally inexpensive models to mimic expensive ones. In this paper, we apply surrogate-assisted parallel tempering where the surrogate mimics a landscape evolution model by estimating the likelihood function from the model. We employ a neural-network-based surrogate model that learns from the history of samples generated. The entire framework is developed in a parallel computing infrastructure to take advantage of parallelism. The results show that the proposed methodology is effective in lowering the computational cost significantly while retaining the quality of model predictions.

Published: July 2020

Abstract. A European EMPIR project, which aims to use large-scale, 5 mm × 200 µm × 50 µm (L×W×H), piezoresistive microprobes for contact resonance
applications, a well-established measurement mode of atomic force
microscopes (AFMs), is being funded. As the probes used in this project are
much larger in size than typical AFM probes, however, some of the
simplifications and assumptions made for AFM probes are not applicable. This study presents a guide on how to systematically create a model that
replicates the dynamic behavior of microprobes. The model includes variables such as air damping, nonlinear sensitivities, and frequency dependencies. The finished model is then verified by analyzing a series of measurements.
Study on the Feasibility of Electricity Generation from Biogas Produced from Municipal Solid Waste and the Biodigestion of Henhouse Manure

Published: July 2020

Despite consisting of residual material in some processes, solid waste still presents huge potential for recycling, reuse, and energy use, either through thermochemistry or biochemistry. Municipal Solid Waste (MSW) can be energetically exploited by converting landfill gas (LFG) to electrical
energy. In addition, animal manure can also undergo biodigestion, generating biogas that can also be harnessed energetically. Achieving economic viability is difficult when evaluating Thermal Power Plants (TPP) using biogas, especially in cases of smaller cities (in the case of LFG) or when
animal populations (biodigestion) are smaller. This study presents three scenarios for electricity generation using biogas in a case study of a small city located in Itanhandu (MG), Brazil. This study sought to evaluate the benefits of using two sources for biogas production, these being LFG
and the anaerobic digestion of henhouse manure. In the first scenario, a project generating electricity using LFG was analyzed. In the second scenario, energy was generated via biogas coming from manure collected at henhouses. The third scenario considered electricity generation from both
sources. The results demonstrate that TPPs based only in LFG are not economically viable, while the other two scenarios present positive results as to their economic viability, showing that the biogas volume coming from manure collected at henhouses is sufficient for electricity generation
at the TPP with landfill gas. This result could be beneficial both as a solution for Solid Waste Management (MSW) as well as providing an additional energy generation solution near to the city.

Authors: Gül Ülküye Dudu
Published: July 2020

All over the world, the treatment of textile wastewater has become a significant problem due to the development of the textile industry. Particularly, the treatment of synthetic dyes, which are found abundantly amounts in textile wastewater, has gained importance. Recent studies have focused on the use of biological treatment technologies to remove pollutants in water. On the other hand, the disposal of wastes from biological treatment technologies was considered as another environmental problem. This study aims to compare the antimicrobial properties of the extract obtained from dye loaded and un-loaded lichen biomass after the biosorption process. According to the results of this study, it was found that the extract obtained from the waste lichen biomass, which has loaded with the textile dye in the decolorization process, showed a similar antimicrobial effect with the unloaded lichen extract. To sum up the waste lichen biomass used to remove textile dyes can be reused for the application of antimicrobial products.
CEO Characteristics and Real Earnings Management in Jordan
Authors: Alhmood Mohammad Abedalrahman , Shaari Hasnah , Al-dhamari Redhwan
Published: July 2020

The Chief Executive Officer (CEOs) tends to be the most influential member of a corporation as they exert control over corporate decisions such as financial disclosure, board structure, and company performance in ensuring enhanced corporate performance and earnings. The issue of earnings management (EM) that has captured the attention of researchers may be among the most critical factors that are linked to financial statement manipulation. Therefore, the current study explored the effects of the personal characteristics of CEOs on real earnings management (REM) practices in Jordan. Data of 58 companies listed on the Amman Stock Exchange for six years from 2013 to 2018 were utilised to achieve this study’s objectives. The results of this study revealed that CEOs’ experience had a significantly positive association with REM. Meanwhile, CEOs’ tenure had no impact on REM among Jordanian firms. Also, the results exposed the presence of a significantly negative association between CEO duality and REM. Finally, CEOs’ political connection was found to have a significantly positive association with REM. This study offers empirical evidence on the effect of CEO characteristics on REM and how such characteristics can lead to exploitation, which brings an impact on the financial reporting quality.

All manufacturing companies of basic industry and chemical sector listed on Indonesia Stock Exchange during the period of 2014-2017 were the population of the study. There were 66 taken as the samples by using purposive sampling technique. There were 39 companies as research samples and 115 as unit of analysis. Data were collected by documentation method. Then, data were analyzed by using descriptive statistics and inferential statistics. The results of the study indicated that managerial ownership and institutional ownership did not significantly affect capital structure, but profitability had a negative and significant effect on capital structure. Firm size did not have any moderating effect between managerial ownership and profitability on capital strucuture, but firm size moderated the effect between institutional ownership and capital structure. It was concluded that only profitability significantly influenced capital structure, and firm size was able to moderate the effect between institutional ownership and capital structure.
Petrology and Geochemical Characteristic of Granitoids From Guéra Massif in the Central Part of Chad: An Example of Mixing Magmas
Authors: Mbaihoudou Diontar , Maurice Kwékam , Martial Fozing Eric , Armand Kagou Dongmo , Jules Tcheumenak Kouémo
Published: July 2020

The granitoids of Guéra Massif are composed of biotite-granite, amphibole-biotite granite and gabbro-diorite and commonly contain micro granular mafic enclaves which vary from monzogabbro to syenite composition. They are metaluminous, high-K calc-alkaline to shoshonitic series. Gabbro-diorite rocks are magnesian while amphibole-biotite granites are magnesian to ferroan, and biotite granites are ferroan. They are enriched in LREEs relative to HREE and display negative anomalies in Nb, Ta and Ti. Fields relationships, petrology and geochemistry indicate that mixing and mingling processes could be more relevant for the genesis of granitoids associated to fractional crystallization. Thus, the presence of mafic enclaves of gabbro-diorite composition in the granites, the resumption of alkaline feldspar xenocrystals in the gabbro-diorites, as well as the linear correlation between the granites and the gabbro-diorites and the intermediate position of the mafic enclaves between the two formations, enable us to propose magmatic mixing as the major process that presided over the evolution of the Guéra granitoids. The delamination of the continental lithosphere during the post-collisional phase of the Pan-African orogeny would have caused the partial melting of the subduction-modofied mantle and lower continental crust and thus produced the magmas of the Guéra granitoids.
The Semimartingale Equilibrium Risk Premium for a Risk Seeking Investor
Authors: Mukupa George M. , Offen Elias R.
Published: July 2020

In this paper, we consider jump amplitudes which are arbitrary and normal to study the risk seeking investor's equilibrium risk premium in the semimartingale market. We realize that, there is no optimal consumption for this investor in the market. The investor's premium differ significantly with risk aversion in both martingale and semimartingale markets in that the risk seeking investor has no optimal consumption and the wealth process only affects the rare-event premia with no effect on the diffusive premia. The compensation for this investor is highly attractive compared to risk aversion in this market.
Nitrobenzene. Determination in workplace air
Authors: Jeżewska Anna , Woźnica Agnieszka
Published: July 2020

Nitrobenzene is a pale yellow oil with an almond-like odor. On an industrial scale it is obtained by nitration of benzene with a mixture of concentrated sulfuric acid, water and nitric acid. The compound is used in the production of aniline. Nitrobenzene is possibly carcinogenic to humans.
The aim of this study was to develop a method for determining concentrations of nitrobenzene in workplace air in the range from 1/10 to 2 of MAC values.
The developed method is based on the adsorption of nitrobenzene on a silica gel, extraction with methanol and chromatographic analysis of the resulting solution. The tests were performed using a liquid chromatograph (HPLC) 1200 series of Agilent Technologies with a diode array detector (DAD). Determinations were performed using an Ultra C18 column (25 cm × 4.6 mm, dp = 5 µm). The procedure was validated according to Standard No. EN 482. On the basis of obtained results, the concentration range was established as 1.8–36 µg/ml, which corresponds to 0.1–2 mg/m3 for 18-L air sample. In the following range, the obtained calibration curve was linear, as evidenced by the regression coefficient at the level of 1. The overall accuracy of the method was 5.38% and its relative total uncertainty was 23.42%.
This method enables selective determination of nitrobenzene in workplace air at concentrations of 0.1–2 mg/m3 in the presence of other compounds, such as methanol, benzene and aniline. The method for determining nitrobenzene is presented in the form of analytical procedure in the Annex.
n-Butyl acetate and its isomers – isobutyl acetate and sec-butyl acetate
Determination in workplace air
Authors: Kowalska Joanna
Published: July 2020

n-Butyl acetate and its isomers, isobutyl acetate and sec-butyl acetate, are colorless, flammable liquids with a fruity odour. Because of their physicochemical properties they are commonly used as organic solvents and compounds of solvent mixtures in various industries. The aim of this study was to develop and validate a method for determining concentrations of n-butyl acetate, isobutyl acetate and sec-butyl acetate in workplace air. The determination method is based on the adsorption of n-butyl acetate and its isomers on activated charcoal (100/50 mg sections), desorption with carbon disulfide and the analysis of the resulting solution with gas chromatography with flame ionization detection (GC-FID). A capillary column with HP-FFAP (50 m × 0.32 mm, i.d. × 0.50 μm film thickness) was used. The method is linear within the working range from 0.24 mg/ml to 4.8 mg/ml, which is equivalent to air concentrations from 24 to 480 mg/m3 for a 10-L air sample. The analytical method described in this paper enables selective determination of analytes in workplace air in presence of coexisting substances. The method is precise, accurate and it meets the criteria for procedures for measuring chemical agents listed in Standard No. EN 482. The method can be used for assessing occupational exposure to n-butyl acetate, isobutyl acetate and sec-butyl acetate and associated risk to workers’ health. The developed method of determining n-butyl acetate and its isomers (isobutyl acetate, sec-butyl acetate) has been recorded as an analytical procedure (see appendix).
Contribution to Decision Tree Induction with Python: A Review
Authors: Lamrini Bouchra
Published: July 2020

Among the learning algorithms, one of the most popular and easiest to understand is the decision tree induction. The popularity of this method is related to three nice characteristics: interpretability, efficiency, and flexibility. Decision tree can be used for both classification and regression kind of problem. Automatic learning of a decision tree is characterised by the fact that it uses logic and mathematics to generate rules instead of selecting them based on intuition and subjectivity. In this review, we present essential steps to understand the fundamental concepts and mathematics behind decision tree from training to building. We study criteria and pruning algorithms, which have been proposed to control complexity and optimize decision tree performance. A discussion around several works and tools will be exposed to analyze the techniques of variance reduction, which do not improve or change the representation bias of decision tree. We chose Pima Indians Diabetes dataset to cover essential questions to understand pruning process. The paper’s original contribution is to provide an up-to-date overview that is fully focused on implemented algorithms to build and optimize decision trees. This contributes to evolve future developments of decision tree induction.

Published: July 2020

Full-Heusler compounds exhibit a variety of magnetic properties such as non-magnetism, ferromagnetism, ferrimagnetism and anti-ferromagnetism. In recent years, they have attracted significant attention as potential thermoelectric (TE) materials that convert thermal energy directly into electricity. This chapter reviews the theoretical and experimental studies on the TE properties of magnetic full-Heusler compounds. In Section 1, a brief outline of TE power generation is described. Section 2 introduces the crystal structures and magnetic properties of full-Heusler compounds. The TE properties of full-Heusler compounds are presented in Sections 3 and 4. The relationship between magnetism, TE properties and order degree of full-Heusler compounds is elaborated.
Integrative redescription of Hypsibius pallidoides Pilato et al., 2011 (Eutardigrada: Hypsibioidea) with the erection of a new genus and discussion on the phylogeny of Hypsibiidae
Authors: Tumanov Denis V.
Published: July 2020

An integrative redescription of Hypsibius pallidoides Pilato, Kiosya, Lisi, Inshina & Biserov, 2011 was undertaken following a reexamination of the type material and new material using high-quality light microscopy, scanning electron microscopy and methods of molecular taxonomy. Detailed morphological investigations revealed a unique complex of characters that precluded the attribution of this species to the genus Hypsibius Ehrenberg, 1848. Furthermore, phylogenetic analyses indicated the affinity of this species within the subfamily Pilatobiinae (Hypsibiidae). Notahypsibius gen. nov. is erected for H. pallidoides and two putatively related species: H. scaber Maucci, 1987 and Ramazzottius arcticus (Murray, 1907). An emended diagnosis for the genus Pilatobius is given, while the subfamily Pilatobiinae lacks a cohesive morphological diagnosis despite representing, at the same time, a well-supported molecular clade. Obvious controversy between the results of the morphological and molecular analyses of the phylogeny of Hypsibioidea is discussed. The distribution of morphological characters such as the claw type, organization of the bucco-pharyngeal apparatus, and egg shell sculpture type within Eutardigrada is analyzed and their phylogenetic significance discussed.
Library strategic planning after COVID-19: Don’t fight the last war

The big guns thumped out their deadly cargo all through the night. The artillery barrage was so relentless that the German offensive, such as it was, halted almost before it even began. All the planning, all the labor, and all the money spent allowed the French troops to remain nestled in the safety of their giant concrete fortresses, which were dug deeply into the security of the earth itself. The Maginot Line was a success. The long and bloody Great War would not be repeated.

Military-affiliated students are a diverse campus constituency and may encounter a number of obstacles to their academic success. At the University of Memphis (UM), the Veteran and Military Student Services (VMSS) center provides a wide-ranging suite of services to engage and support military-affiliated students. This article describes how two UM departments, the University Libraries and VMSS, collaborated to facilitate the discovery and circulation of an existing collection of textbooks for military-affiliated students.
Impact of Immunotherapy on the Survival of Patients With Cancer and Brain Metastases

Background: Immunotherapy has shown excellent efficacy in various cancers. However, there is a lack of knowledge regarding the significant role of immunotherapy in patients with brain metastases (BMs). The objective of this study was to investigate, using the National Cancer Database, the impact of immunotherapy on the overall survival (OS) of patients with BMs who did not receive definitive surgery of the primary tumor. Patients and Methods: Patients diagnosed with the primary cancer of non–small cell lung cancer, small cell lung cancer, other types of lung cancer, breast cancer, melanoma, colorectal cancer, or renal cancer who had BMs at the time of diagnosis were identified from the National Cancer Database. We assessed OS using a Cox proportional hazards model adjusted for age at diagnosis, sex, race, education level, income level, residential area, treatment facility type, insurance status, Charlson-Deyo comorbidity status, year of diagnosis, primary tumor type, and receipt of chemotherapy, radiation therapy (RT), and/or immunotherapy, because these factors were significantly associated with OS in the univariable analysis. Results: Of 94,215 patients who were analyzed, 3,097 (3.29%) received immunotherapy. In the multivariable analysis, immunotherapy was associated with significantly improved OS (hazard ratio [HR], 0.694; 95% CI, 0.664–0.726; P<.0001) compared with no immunotherapy. Treatment using chemotherapy plus immunotherapy was significantly associated with improved OS (HR, 0.643; 95% CI, 0.560–0.738; P<.0001) compared with chemotherapy without immunotherapy. RT plus immunotherapy was also associated with significantly improved OS (HR, 0.389; 95% CI, 0.352–0.429; P<.0001) compared with RT alone. Furthermore, chemoradiation (CRT) plus immunotherapy was associated with significantly improved OS (HR, 0.793; 95% CI, 0.752–0.836; P<.0001) compared with CRT alone. Conclusions: In this comprehensive analysis, the addition of immunotherapy to chemotherapy, RT, and CRT was associated with significantly improved OS in patients with BMs. The study warrants future clinical trials of immunotherapy in patients with BMs, who have historically been excluded from these trials.
NCCN Policy Summit: Defining, Measuring, and Applying Quality in an Evolving Health Policy Landscape and the Implications for Cancer Care

Quality measurement is a critical component of advancing a health system that pays for performance over volume. Although there has been significant attention paid to quality measurement within health systems in recent years, significant challenges to meaningful measurement of quality care outcomes remain. Defining cost can be challenging, but is arguably not as elusive as quality, which lacks standard measurement methods and units. To identify industry standards and recommendations for the future, NCCN recently hosted the NCCN Oncology Policy Summit: Defining, Measuring, and Applying Quality in an Evolving Health Policy Landscape and the Implications for Cancer Care. Key stakeholders including physicians, payers, policymakers, patient advocates, and technology partners reviewed current quality measurement programs to identify success and challenges, including the Oncology Care Model. Speakers and panelists identified gaps in quality measurement and provided insights and suggestions for further advancing quality measurement in oncology. This article provides insights and recommendations; however, the goal of this program was to highlight key issues and not to obtain consensus.
