Authors: Yokoyama Shohei , Nakagawa Ichiro , Kotsugi Masashi , Wajima Daisuke , Wada Takeshi , Kichikawa Kimihiko , Nakase Hiroyuki
Published: February 2019

The results of recent clinical and experimental studies suggest that the most important factor associated with the pathogenesis of dural arteriovenous fistula (AVF) is sinus thrombosis and subsequent venous or intrasinus hypertension. Here, we describe two patients who each developed a dural AVF after a posterior fossa craniotomy on the side of the nondominant or hypoplastic transverse (TS)-sigmoid (SS) sinuses. A 63-year-old female underwent surgical resection of a meningioma in the left cerebellopontine angle. Preoperative subtraction digital angiography (DSA) revealed a hypoplastic, ipsilateral left TS-SS and the sinus occlusion was revealed after surgery. Sixteen months later, she presented with a progressive left retroauricular, pulse-synchronous bruit. An AVF in the left TS-SS region was diagnosed by DSA and treated with transvenous coil embolization. The patient recovered without neurological deterioration. A 56-year-old female underwent surgical removal of an epidermoid tumor in the right cerebellopontine angle. Preoperative DSA revealed severe, ipsilateral right TS stenosis and the sinus occlusion was revealed after surgery. Two years later, she presented with the progressive right retroauricular, pulse-synchronous bruit, which was diagnosed by DSA as dural AVF in the right TS-SS region. She was treated with transvenous coil embolization and recovered without neurological deterioration. Sinus manipulation during intracranial surgery carries a potential risk of dural AVF development and this should be carefully considered, even when the ipsilateral TS-SS is nondominant or appears hypoplastic.

Published: February 2019

This research evaluated the effectiveness of the implementation of water resource preservation areas in the Hydrographical Basin of Andreas Stream, county of Vera Cruz, RS, Brazil, established through Payment for Environmental Services (PES), using an environmental monitoring program to assess physical, chemical and microbiological variables. The PES is linked to the "Water Guardian" project, which aims to ensure the preservation of water resources by paying farmers for providing the environmental services to protect the springs and riparian areas that lie within their properties. Twenty sampling stations were selected for collecting water samples monthly during the period July 2012 to June 2014 (460 samples) to evaluate the following variables: water temperature, pH, turbidity, dissolved oxygen, biochemical oxygen demand, nitrate, ammonia nitrogen, phosphate, total dissolved solids and thermotolerant coliforms. The evaluation was made based on decree 357/2005 of the National Environmental Council (CONAMA) and by applying the Water Quality Index (WQI). The results indicated a significant improvement in the water quality when comparisons were made between the periods before and after the installation of the preservation areas. The sampling points classified as “good” (CONAMA and WQI), which indicates water of good quality that is appropriate for multiple uses, increased from 52.0% to 72.0%. In this sense, promoting the preservation of headwaters and riparian zones becomes of fundamental importance and highlights the role of PES as an operational tool for water resource preservation.

Local and remote temperature response of regional SO2 emissions
Authors: Lewinschal Anna , Ekman Annica M. L. , Hansson Hans-Christen , Sand Maria , Berntsen Terje K. , Langner Joakim
Published: February 2019

Abstract. Short-lived anthropogenic climate forcers (SLCFs), such as sulfate aerosols,
affect both climate and air quality. Despite being short-lived, these forcers
do not affect temperatures only locally; regions far away from the emission
sources are also affected. Climate metrics are often used in a policy context
to compare the climate impact of different anthropogenic forcing agents.
These metrics typically relate a forcing change in a certain region with a
temperature change in another region and thus often require a separate model
to convert emission changes to radiative forcing (RF) changes. In this study, we used a coupled Earth system model, NorESM (Norwegian Earth
System Model), to calculate emission-to-temperature-response metrics for
sulfur dioxide (SO2) emission changes in four different
policy-relevant regions: Europe (EU), North America (NA), East Asia (EA) and
South Asia (SA). We first increased the SO2 emissions in each
individual region by an amount giving approximately the same global average
radiative forcing change (−0.45 Wm−2). The global mean temperature
change per unit sulfur emission compared to the control experiment was
independent of emission region and equal to
∼0.006 K(TgSyr−1)−1. On a regional scale, the Arctic showed
the largest temperature response in all experiments. The second largest
temperature change occurred in the region of the imposed emission increase,
except when South Asian emissions were changed; in this experiment, the
temperature response was approximately the same in South Asia and East Asia.
We also examined the non-linearity of the temperature response by removing
all anthropogenic SO2 emissions over Europe in one experiment. In
this case, the temperature response (both global and regional) was twice that
in the corresponding experiment with a European emission increase. This
non-linearity in the temperature response is one of many uncertainties
associated with the use of simplified climate metrics.
Large-volume air sample system for measuring 34S∕32S isotope ratio of carbonyl sulfide
Authors: Kamezaki Kazuki , Hattori Shohei , Bahlmann Enno , Yoshida Naohiro
Published: February 2019

Abstract. Knowledge related to sulfur isotope ratios of carbonyl sulfide (OCS or COS),
the most abundant atmospheric sulfur species, remains scarce. An earlier
method developed for sulfur isotopic analysis for OCS using S+
fragmentation by an isotope ratio mass spectrometer is inapplicable for
ambient air samples because of the large samples required (approx. 500 L of
500 pmol mol−1 OCS). To overcome this difficulty, herein we present a
new sampling system for collecting approximately 10 nmol of OCS from ambient
air coupled with a purification system. Salient system features are
(i) accommodation of samples up to 500 L (approx. 10 nmol) of air at
5 L min−1; (ii) portability of adsorption tubes (1∕4 in. (0.64 cm)
outer diameter, 17.5 cm length, approximately 1.4 cm3 volume) for
preserving the OCS amount and δ34S(OCS) values at −80 ∘C
for up to 90 days and 14 days; and (iii) purification OCS from other
compounds such as CO2. We tested the OCS collection efficiency of
the systems and sulfur isotopic fractionation during sampling. Results show
precision (1σ) of δ34S(OCS) values as 0.4 ‰ for
overall procedures during measurements for atmospheric samples. Additionally,
this report presents diurnal variation of δ34S(OCS) values
collected from ambient air at the Suzukakedai campus of the Tokyo Institute
of Technology located in Yokohama, Japan. The observed OCS concentrations and
δ34S(OCS) values were, respectively, 447–520 pmol mol−1 and
from 10.4 ‰ to 10.7 ‰ with a lack of diurnal variation. The
observed δ34S(OCS) values in ambient air differed greatly from
previously reported values of δ34S(OCS) = (4.9±0.3) ‰ for compressed air collected at Kawasaki, Japan, presumably
because of degradation of OCS in cylinders and collection processes for that
sample. The difference of atmospheric δ34S(OCS) values between
10.5 ‰ in Japan (this study) and ∼13 ‰ recently
reported in Israel or the Canary Islands indicates that spatial and temporal
variation of δ34S(OCS) values is expected due to a link between
anthropogenic activities and OCS cycles. The system presented herein is
useful for application of δ34S(OCS) for investigation of OCS
sources and sinks in the troposphere to elucidate its cycle.
The cost function of the data fusion process and its application
Authors: Ceccherini Simone , Zoppetti Nicola , Carli Bruno , Cortesi Ugo , Del Bianco Samuele , Tirelli Cecilia
Published: February 2019

Abstract. When the complete data fusion method is used to fuse inconsistent measurements, it is necessary to add to the measurement covariance matrix of each fusing profile a covariance matrix that takes into account the inconsistencies. A realistic estimate of these inconsistency covariance matrices is required for effectual fused products. We evaluate the possibility of assisting the estimate of the inconsistency covariance matrices using the value of the cost function minimized in the complete data fusion. The analytical expressions of expected value and variance of the cost function are derived. Modelling the inconsistency covariance matrix with one parameter, we determine the value of the parameter that makes the reduced cost function equal to its expected value and use the variance to assign an error to this determination. The quality of the inconsistency covariance matrix determined in this way is tested for simulated measurements of ozone profiles obtained in the thermal infrared in the framework of the Sentinel 4 mission of the Copernicus programme. As expected, the method requires a sufficient statistics and poor results are obtained when a small numbers of profiles are being fused together, but very good results are obtained when the fusion involves a large number of profiles.
The oceanic cycle of carbon monoxide and its emissions to the atmosphere
Authors: Conte Ludivine , Szopa Sophie , Séférian Roland , Bopp Laurent
Published: February 2019

Abstract. The ocean is a source of atmospheric carbon monoxide (CO), a key
component for the oxidizing capacity of the atmosphere. It constitutes a
minor source at the global scale, but could play an important role far from
continental anthropized emission zones. To date, this natural source is
estimated with large uncertainties, especially because the processes driving
the oceanic CO are related to the biological productivity and can thus have a
large spatial and temporal variability. Here we use the NEMO-PISCES (Nucleus
for European Modelling of the Ocean, Pelagic Interaction Scheme for Carbon
and Ecosystem Studies) ocean general circulation and biogeochemistry model to
dynamically assess the oceanic CO budget and its emission to the atmosphere
at the global scale. The main biochemical sources and sinks of oceanic CO are
explicitly represented in the model. The sensitivity to
different parameterizations is assessed. In combination to the model, we
present here the first compilation of literature reported in situ oceanic CO
data, collected around the world during the last 50 years. The main processes
driving the CO concentration are photoproduction and bacterial consumption
and are estimated to be 19.1 and 30.0 Tg C yr−1 respectively with our
best-guess modeling setup. There are, however, very large uncertainties on
their respective magnitude. Despite the scarcity of the in situ CO
measurements in terms of spatiotemporal coverage, the proposed best
simulation is able to represent most of the data (∼300 points) within a
factor of 2. Overall, the global emissions of CO to the atmosphere
are 4.0 Tg C yr−1, in the range of recent estimates, but are very
different from those published by Erickson in (1989), which were the only
gridded global emission available to date. These oceanic CO emission
maps are relevant for use by atmospheric chemical models, especially to study
the oxidizing capacity of the atmosphere above the remote ocean.
Estimations of rip current rescues and drowning in the United States
Authors: Brewster B. Chris , Gould Richard E. , Brander Robert W.
Published: February 2019

Abstract. Rip currents are the greatest
hazard to swimmers on surf beaches, but due to a lack of consistent incident
reporting in many countries, it is often difficult to quantify the number of
rip-current-related rescues and
drowning deaths occurring along surf beaches. This study examines this
problem using rescue data reported to the United States Lifesaving
Association (USLA) by surf beach rescuers from 1997 through 2016. These data
were checked, corrected, and culled so that only data from surf beach rescue
agencies that reported the primary cause of rescue were included. Results
show that rip currents are the primary cause of 81.9 % of rescues on surf
beaches, with regional variation from 75.3 % (East Coast) to 84.7 %
(West Coast). These values are significantly higher than those previously
reported in the scientific literature (e.g., 36.5 %, 53.7 %). Using
this value as a proxy when examining overall surf beach drowning fatalities,
it is suggested that more than 100 fatal drownings per year occur due to rip
currents in the United States. However, it is clear that the United States
data would benefit by an increase in the number of lifeguard agencies which
report surf-related rescues by primary cause.
Large carbon cycle sensitivities to climate across a permafrost thaw gradient in subarctic Sweden
Authors: Chang Kuang-Yu , Riley William J. , Crill Patrick M. , Grant Robert F. , Rich Virginia I. , Saleska Scott R.
Published: February 2019

Abstract. Permafrost peatlands store large amounts of carbon potentially vulnerable to
decomposition. However, the fate of that carbon in a changing climate remains
uncertain in models due to complex interactions among hydrological,
biogeochemical, microbial, and plant processes. In this study, we estimated
effects of climate forcing biases present in global climate reanalysis
products on carbon cycle predictions at a thawing permafrost peatland in
subarctic Sweden. The analysis was conducted with a comprehensive
biogeochemical model (ecosys) across a permafrost thaw gradient
encompassing intact permafrost palsa with an ice core and a shallow active
layer, partly thawed bog with a deeper active layer and a variable water
table, and fen with a water table close to the surface, each with distinct
vegetation and microbiota. Using in situ observations to correct
local cold and wet biases found in the Global Soil Wetness Project Phase 3
(GSWP3) climate reanalysis forcing, we demonstrate good model performance by
comparing predicted and observed carbon dioxide (CO2) and methane
(CH4) exchanges, thaw depth, and water table depth. The simulations
driven by the bias-corrected climate suggest that the three peatland types
currently accumulate carbon from the atmosphere, although the bog and fen
sites can have annual positive radiative forcing impacts due to their higher
CH4 emissions. Our simulations indicate that projected precipitation
increases could accelerate CH4 emissions from the palsa area, even
without further degradation of palsa permafrost. The GSWP3 cold and wet
biases for this site significantly alter simulation results and lead to
erroneous active layer depth (ALD) and carbon budget estimates. Biases in
simulated CO2 and CH4 exchanges from biased climate forcing
are as large as those among the thaw stages themselves at a landscape scale
across the examined permafrost thaw gradient. Future studies should thus not
only focus on changes in carbon budget associated with morphological changes
in thawing permafrost, but also recognize the effects of climate forcing
uncertainty on carbon cycling.

Politicization of Students Politics in Bangladesh: Historical Experiences and Contemporary Trends
Authors: Nasrin Salma , Rahman Md. Mashiur
Published: February 2019

The purpose of the study is to review the long glorious history of student politics in Bangladesh under different regime and to illustrate the recent trends of student politics. The study includes two parts, first part is entirely based on a literature review and second portion includes a field survey. Twenty two literatures have been selected as a data set through searching Web of Science, SCOPUS and Google Scholar databases by using the relevant keywords for reviewing the past experiences of student politics. On the other hand, a field survey has been conducted using the unknown population sampling technique, where student’s perceptions toward present student politics have been explored. From the literature review, it is found that student politics in Bangladesh has a magnificent past history of fighting and greatest sacrifice for the national interest during all turning points of the country, including anti-British movement in 1940s, the language movement of 1948 to 1952, six point movement of 1966, mass upsurge of 1969, liberation war of 1971, and the falling of military dictator Ershad in 1990s. Unfortunately, the impression of this historic student politics have been transformed to the personal goal accomplishment after starting democratic forms of government in 1991, when student organizations are mostly found to be used as the political weapons of mainstream political parties. The results of field survey also complemented that the perception of present party backed student politics is mostly focused on personal agenda or their mother party’s political agenda rather than national or common interest of the students.
Dialect syntax as a testbed for models of innovation and change: Modals and negative concord in the Syntactic Atlas of Welsh Dialects
Authors: Willis David
Published: February 2019

This paper introduces the pilot project for the Syntactic Atlas of Welsh Dialects, setting out the procedures for data collection and sketching a case study for one variable within the dataset, namely the patterns of negative concord found with the negative modal cau ‘won’t’. This item is a relatively recent innovation, and it is currently undergoing increasing integration into the negative concord system. The atlas fieldwork establishes current patterns of dialect variation, showing significant age variation indicative of change in progress and the rise of negative concord in this context. On the basis of this, it is argued that the diffuse geographical patterns attested are best interpreted as evidence of multiple innovation across a wide area, with new speakers re-implementing the innovation (“multiple reactuation”). A formal analysis is sketched out, treating the change as moving along a pathway of feature change with semantic features shifting to interpretable syntactic features and then to uninterpretable syntactic ones. This analysis is consistent with the dialect patterns and interspeaker implicational hierarchies found in the data.
The implementation of the Marketing Communication Mix using Internet Platforms on Turkish Cypriot Hotels
Authors: Alhawamdeh Zead M.
Published: February 2019

The advent of the internet has reshaped the way humans live, and the way business is done globally. Although the tide of globalization had set in long before the advent of the internet, the coming of the internet expedited it. This is even more so for the field of tourism which relies on the cross cultural and global fascination the world’s citizens hold for the various ‘other sides’ of the planet. The benefits of marketing through the internet is for some an overwhelming phenomena. Tourism forms have however had to catch up fast. Today the internet is used in such marketing schemes as online sales promotion, online advertising, Thus the traditional marketing communications mix have been found to have a new avenue in the world wide web. This study set out to understand the rate at which North Cyprus hoteliers are catching up and more specifically to understand how elements of the marketing communications mix are deployed through their websites. Three, four and five star hotels graded by the North Cyprus Hoteliers Association known as KITOB were used as the sample population for this study.

The Evolution of Private Labels in Food Proposals: The Case of the Top Four Italian Retailers and the Purchase Propensity of Consumers
Authors: Morrone Domenico , Schena Rosamartina
Published: February 2019

The presence of products marked with the brand of the retailer is not a novelty in the mass distribution circuit. In the last decades, private labels (PLs) increased in a relevant way, upgrading the competition with the proposals coming from branded products. Since the beginning of the last century, this comparison attracted the attention of many scholars. Different factors were analyzed as, for example, the brand value, the trust in the distribution company or other elements that underlined the acceptance of PLs products. Actually, thanks to a new and consolidated trend in the market, it is possible to register an evolution of PLs, with a relevant specialization. The aim of the present work is to analyze, in the Italian context, this evolution, observing the food proposals of the main PLs. In addition, this differentiation is compared with the purchase propensity of consumers. The final purpose is to discover the effective match between market demand and the value propositions of qualified Italian retailers. The study is organized with a theoretical background to define in a structured way the topic. After, there are the evidences of the research, carried out on a double way. First there is the panel of the PLs proposals at the beginning of 2018, referred to the first four groups in the Italian market. Therefore, considering the categories represented by these products, a survey has been conducted to discover the acceptance of the consumers. Final results show how this panorama is become complex and when differentiation is able to fit the desires of customers. This study provides relevant implications from the marketing point of view. It is a valid contribution for practitioners and scholars, giving a further vision in the evolution of PLs foodstuffs.

Het voortbestaan van de landsadvocaat; overwegingen bij een 50-jarig bestaan

Het historische argument voor inschakeling van de landsadvocaat ligt in het gebrek aan juristen binnen de overheid. Inmiddels is een groot aantal juristen binnen de overheid werkzaam, maar de landsadvocaat is gebleven. De drie later opgekomen argumenten – het rechtstatelijke, het expertise- en het eenheidsargument – kunnen het voortbestaan van de landsadvocaat met de huidige omvangrijke inschakeling nauwelijks verklaren. Voorstellen om de rol van de landsadvocaat terug te dringen, meest uitdrukkelijk gedaan door de Visitatiecommissie Juridische functie en Wetgeving, heeft het kabinet niet gehonoreerd. Zijn deskundigheidsprestige en de steun van overheidsjuristen schragen de functie van de landsadvocaat. Niettemin lijkt plaats te zijn voor een Nederlandse variant van de attorney general.

Social comparison orientation mediates the relationship between neuroticism and passive Facebook use
Authors: Rozgonjuk Dmitri , Ryan Tracii , Kuljus Joosep-Kristjan , Täht Karin , Scott Graham G.
Published: February 2019

Passive Facebook use, which involves engaging in non-socially orientated behavior on the popular social networking site, is associated with a range of negative outcomes, including social anxiety, loneliness, jealousy, and depressed mood. Research indicates that passive Facebook use may also be related to a tendency to engage in social comparison with others. In addition, there is some evidence that this tendency is more prevalent in individuals high in the personality trait neuroticism. The aim of this study was to investigate the relationships between passive Facebook use, neuroticism, and social comparison orientation (SCO). In addition, we explored whether SCO mediates the potential relationship between neuroticism and passive Facebook use. In a cross-sectional study, 318 Estonian Facebook users completed the Multidimensional Scale of Facebook Use (to ascertain passive Facebook use), the Extra Short Big Five Personality Inventory, and the Iowa-Netherlands Comparison Orientation Scale. The results revealed positive bivariate-correlations between passive Facebook use, neuroticism, and SCO. In addition, SCO mediated the relationship between neuroticism and passive Facebook use. These findings suggest that people higher in neuroticism are more prone to social comparison, which is associated with passive Facebook use. These findings are discussed, and several directions for future research are provided.

Authors: Hou Yubo , Xiong Dan , Jiang Tonglin , Song Lily , Wang Qi
Published: February 2019

This research examined the relations of social media addiction to college students' mental health and academic performance, investigated the role of self-esteem as a mediator for the relations, and further tested the effectiveness of an intervention in reducing social media addiction and its potential adverse outcomes. In Study 1, we used a survey method with a sample of college students (N = 232) and found that social media addiction was negatively associated with the students' mental health and academic performance and that the relation between social media addiction and mental health was mediated by self-esteem. In Study 2, we developed and tested a two-stage self-help intervention program. We recruited a sample of college students (N = 38) who met criteria for social media addiction to receive the intervention. Results showed that the intervention was effective in reducing the students’ social media addiction and improving their mental health and academic efficiency. The current studies yielded original findings that contribute to the empirical database on social media addiction and that have important theoretical and practical implications.

Abstract
This research work presents the study of the useful life of a cardboard Point of Purchase commercially known as POP. The proposed POP, is used as a tool of marketing to distribute, store and sell 700 tetrapack ™ packages of one liter per unit. The Integral Model of New Products (MIDNP) in its Phase II was used in this study to create a prototype and includes industrial design, failure analysis, Finite Element Analysis (FEM) and experimental evaluation with electrical extensometry measurements. It considers also the redesign and modifications of the manufacturing process. In the experiment, the prototype was subjected to a maximum load during 4500 hours in order to identify its mechanical behavior. The importance of this evaluation can be seen in the case when a POP is not in good physical condition, the marketing process is interrupted even before the presence of mechanical failures. Its useful life is then reduced because the visual effect does not stimulate the intention of purchase of the customer. An improvement of 25% was obtained as a result of the application of the MIDNP in comparison with other traditional designs presented in this study, no visual deformations were observed before 2500 hours of the experiment. The implementation of tools, which are common in structural mechanics, has demonstrated that no visible deformations were observed in the prototype but not after 2500 hours of duration of the experiment.

Keywords: Cardboard, Point of Purchase, Integral Model of Design New Products, extensometry, useful life.
Data Management Practices in Academic Library Learning Analytics: A Critical Review
Authors: Briney Kristin A
Published: February 2019

INTRODUCTION Data handling in library learning analytics plays a pivotal role in protecting patron privacy, yet the landscape of data management by librarians is poorly understood. METHODS This critical review examines data-handling practices from 54 learning analytics studies in academic libraries and compares them against the NISO Consensus Principles on User’s Digital Privacy in Library, Publisher, and Software-Provider Systems and data management best practices. RESULTS A number of the published research projects demonstrate inadequate data protection practices including incomplete anonymization, prolonged data retention, collection of a broad scope of sensitive information, lack of informed consent, and sharing of patron-identified information. DISCUSSION As with researchers more generally, libraries should improve their data management practices. No studies aligned with the NISO Principles in all evaluated areas, but several studies provide specific exemplars of good practice. CONCLUSION Libraries can better protect patron privacy by improving data management practices in learning analytics research.
Strategies for Supporting OER Adoption through Faculty and Instructor Use of a Federated Search Tool
Authors: Anderson Talea , Leachman Chelsea
Published: February 2019

INTRODUCTION Open educational resources (OER) are gaining traction in higher education and becoming accepted by academics as a viable means for delivering course content. However, these resources can be difficult to find and use, both due to low visibility and confusion about licensing. This article describes one university’s work with faculty members to identify barriers in their search process when they are looking to adopt OER. DESCRIPTION OF PROGRAM A scholarly communication librarian and science librarian partnered to collect faculty and instructor reactions to a particular OER search tool, with the intention of better understanding the difficulties encountered during the search process. Eight interviews were conducted as participants were asked about their preferences when it comes to locating OER, understanding licensing information, and adopting materials for class. NEXT STEPS From these interviews, the librarians identified practical recommendations for instruction/liaison librarians and technical services/systems librarians as they continue working to support faculty and instructors through the OER discovery and selection process. These recommendations relate to four themes uncovered in interviews with faculty and instructors: the need for increased transparency in search tools, the importance of intuitive narrowing and broadening features in search tools, the need for detailed and consistent metadata in OER records, and the need for clarity in intellectual property statements. The librarians note that these recommendations might best be pursued through wide-scale collaboration across library units and, more generally, between libraries, consortia, and institutions.

Recent field trips to Member III of the Naobaogou Formation, Nei Mongol, China yielded new fossil discoveries, increasing our knowledge of the late Permian continental fauna from China. We present here a new large therocephalian, Jiufengia jiai gen. et sp. nov., represented by a partial skull with mandibles and part of the postcranial skeleton. This is the second therocephalian recovered from the Naobaogou faunal association and, in turn, the second akidnognathid from this unit and from China. The new taxon shows clear differences from Shiguaignathus wangi, the akidnogathid previously reported from the Naobaogou Formation: the presence of four upper postcanines, of a large suborbital vacuity, and the flat ventral surface of the vomer, lacking a ventromedian crest. Updating a previous phylogeny of therocephalians, we recover the new species as a basal member of Akidnognathidae, above a basal polytomy including the other two Laurasian akidnognathids, Shiguaignathus and Annatherapsidus, adding support to the hypothesis that this group originated in Laurasia.

Published: February 2019

This work characterizes and compares the community of anemones at two coralline areas in the Tayrona National Natural Park, in the Colombian Caribbean, and also relates the species that were found with some important characteristics of the reef community as well as with factors that can condition its structure. The statistical tests performed allowed to differentiate two kinds of landscapes: the shallow mixed coral reef and the deep one. A total of 15 species of anemones were found, four belonging to the Order Corallimorpharia and 11 to the order Actiniaria, distributed over the coralline landscapes of the area. The tests used to determine the distribution of anemones inside the corridors measured, showed the formation of two similar groups of corridors to those obtained for the landscape that in its turn, represent two groups of anemones, those of shallow reefs and those of deep reefs. The tests used for each kind of anemone in respect to the characteristics of the reef environment suggest that each species has its own preferences regarding the habitat selection. However, relating the anemones with the landscape, anemones with the presence of certain coral species and anemones with the general reef landscape can create two basic categories.

Authors: Corring Deborah , O’Reilly Richard , Sommerdyk Christina , Russell Elizabeth
Published: February 2019

Qualitative studies provide a different kind of understanding of the effectiveness of community treatment orders (CTOs) by exploring the perspectives of stakeholders. This article documents a systematic review of 12 qualitative studies that explored the views of families of individuals on a CTO. Relevant databases and grey literature were searched. Themes were identified: the benefits of CTOs outweigh the disadvantages, CTOs increased their involvement in care, and families were dissatisfied with aspects of the CTO process. Recommendations include how to maximize the benefits of CTOs, reduce administrative burdens and employ strategies to increase involvement of families in the care of their loved ones.
Pressure Measurement
Authors: Große Bley W.
Published: February 2019

This article explains the principles of total pressure measurement in vacuum systems. Vacuum gauges are characterized by a great variety of physical principles to cover the whole vacuum pressure range starting at atmospheric pressure over gross vacuum, fine vacuum, and ultrahigh vacuum down to extreme high vacuum. These ranges cover about 12 decades of pressure, and there is no physical principle which could cover all of these. This article describes the different types of vacuum gauges, each using a different physical effect for specific pressure decades. In order to cover a broader range in one gauge, instruments with a combination of principles have been developed in recent years.
Leak Detection
Authors: Bley W.Große
Published: February 2019

This article explains the purpose of leak testing in laboratories and in the manufacturing and maintenance of systems. It describes the techniques for testing components and systems for leaks. Methods for pressurized components and those used in vacuum systems are described. Simple techniques to detect gross leaks without any additional equipment and, on the other hand, the measurement of fine and ultrafine leaks with leak detectors and tracer gas are presented. The mass spectrometer helium leak detector is the most frequently used instrument for integral testing and the localization of leaks and the measurement of leakage rates. With a sniffer device it may also be used for pressurized systems and components. The importance of test leaks for the calibration of leak detectors and leak testing systems is pointed out.

Published: February 2019

Chemical solution deposition (CSD) can offer economic access to large area coatings, which are required to handle significant amounts of energy in innovative applications. CSD represents an umbrella term encompassing various methods such as sol–gel, metallo‐organic decomposition (MOD), and chemical bath deposition (CBD), which are used for the fabrication of functional metal chalcogenide films. These methods are all based on the layer fabrication from precursors dissolved in the liquid phase, which are transformed into the final functional film material by different working principles. The differences are related to the involved chemistry, solvent, temperatures, and heating processes, as described herein. In addition, chemical and physical deposition methods are briefly compared, highlighting their advantages and disadvantages.

Published: February 2019

One of the most important applications of sol–gel processing is in the preparation of thin films. Thin‐film formation is possible due to deposition of alkoxide followed by exposure to moisture. There are various methods for thin‐film coating or deposition using sol–gel technique. However, the basic steps are almost similar, which include exhausting, excess deposit material processing, and then drying. The physical properties and microstructure of films (density, porosity etc.) are governed by the structure of the colloidal species in the dispersion. The criteria governing the deposition along with the methods of deposition and their applications are discussed in this article.

Published: February 2019

Intensity, wavevector, phase, and polarization are the most important parameters of any light beam. Understanding the wavevector distribution has emerged as a very important problem in recent days, especially at nanoscale. It provides unique information about the light–matter interaction. Back focal plane or Fourier plane imaging and spectroscopy techniques help to measure wavevector distribution not only from single molecules and single nanostructures but also from metasurfaces and metamaterials. This article provides a birds‐eye view on the technique of back focal imaging and spectroscopy, different methodologies used in developing the technique, and applications including angular emission patterns of fluorescence and Raman signals from molecules, elastic scattering, etc. We first discuss on the information one can obtain at the back focal plane of the objective lens according to both imaging and spectroscopy viewpoints and then discuss the possible configurations utilized to project back focal plane of the objective lens onto the imaging camera or to the spectroscope. We also discuss the possible sources of error in such measurements and possible ways to overcome it and then elucidate the possible applications.

Published: February 2019

In this article, we present an overview of the various photonic aspects involved in different techniques for explosives detection on field and in the lab. We confine this synopsis to only laser‐based techniques for detecting explosive molecules in point or proximal setup (laser source and detectors are in the proximity of sample) and in standoff mode (laser and detectors are at certain distance from the sample). The techniques considered in this overview are (a) laser‐induced breakdown spectroscopy (LIBS), (b) Raman spectroscopy and its variants [surface‐enhanced Raman spectroscopy (SERS), coherent anti‐Stokes Raman spectroscopy (CARS), and spatial offset Raman spectroscopy (SORS)], (c) terahertz (THz) spectroscopy, and (d) photoacoustic spectroscopy (PAS). Various photonic aspects related to these techniques such as (i) laser sources used and the future requirements, (ii) detectors employed at present and improvements required, (c) design and advances in variety of optics used for illuminating, collimating, collecting, focusing, etc., and (d) integration of all these components for the creation of efficient portable devices for explosives detection in the laboratory and field are discussed in detail. We also present results obtained through some of our efforts toward trace and standoff explosives detection using SERS and femtosecond LIBS techniques, respectively.
