Non-normative Connections between Work and Family: The Gendered Career Consequences of Being a Dual-career Academic
Authors: Zhang Hong , Kmec Julie A.
Published: May 2018

We investigate the way norms regarding the connections between work and family influence the career consequences of being a dual-career academic. We pay special attention to “gender deviants”—men who indicate that their career is secondary to that of their wife’s career, and women who say their career is primary to that of their husband’s. Analyses using survey data from faculty in seven U.S. universities find male gender conformists (men who perceive their career as primary) report fewer negative career consequences than the other groups. Gender deviants have the lowest levels of organizational commitment. Female and male gender egalitarians (ranking their career as equal) report greater organizational commitment. Gender conformity—that is, ranking one’s career and relationship in the manner society expects—benefits men more so than women. We discuss implications for findings, particularly as they relate to recruitment and retention of dual-career academics in higher education institutions.
Ortner’s syndrome: Focused cardiac ultrasound and rapid ultrasound in shock examination at emergency department unfold the life-threatening cause for a cardiovocal condition
Authors: Abd Samat Azlan Helmy , Embong Hashim
Published: May 2018

Introduction:

Ortner’s syndrome is a rare condition, known as cardiovocal condition as patients present with hoarseness of voice due to cardiovascular causes.

Case presentation:

We present a case of Ortner’s syndrome secondary to leaking thoracic aortic aneurysm in a patient who came to emergency department with hypotension and hoarseness of voice for 3 months. Focused cardiac ultrasound (FOCUS) and rapid ultrasound in shock (RUSH) were performed which revealed a thoracic aortic arch aneurysm.

Discussion:

Focused cardiac ultrasound and rapid ultrasound in shock examination in the emergency department had expedited the diagnosis of this rare condition, hence the subsequent definitive investigation and management.

Conclusion:

This case highlights the need for high index of suspicion for thoracic aneurysm in patients with unexplained cardiovocal symptoms. It also highlights the importance of point-of-care ultrasound in the emergency department and the significance of utilizing the suprasternal view to look for pathology at the arch of aorta.

Published: May 2018

Introduction. Solid/conventional ameloblastoma (AM) and unicystic ameloblastoma (UAM) are the most frequent benign epithelial odontogenic tumors located in the maxillary region, and their treatment usually consists of extensive surgical resection. Therefore, it is relevant to study molecular markers to better understand the biological behavior of these tumors. The aim of this study was to describe and compare the expression of proteins related to cellular proliferation: Ki-67 and MCM4-6 complex. Materials and Methods. An immunohistochemistry technique was performed, with antibodies against Ki-67, MCM4, MCM5, and MCM6, in 10 AM and 10 UAM tumors. The results were quantified using label index and analyzed statistically. Results. AM and UAM had greater expression of MCM6, followed by MCM5, MCM4, and Ki-67 ( P < .05). Immunoexpression of Ki-67 and MCM5 was exclusively nuclear, whereas the expression of MCM4 and MCM6 was nuclear and cytoplasmic. Conclusion. The results suggest that MCM5 is a trustable cell proliferation marker with higher sensitivity compared with Ki-67 and may be useful to predict the biological behavior of AM and UAM. Despite this, further studies are necessary, including a correlation with clinical parameters to confirm these findings.
Sanctuary Cities: Public Attitudes Toward Enforcement Collaboration Between Local Police and Federal Immigration Authorities
Authors: Casellas Jason P. , Wallace Sophia Jordán
Published: May 2018

Local law enforcement has dramatically increased its cooperation with federal immigration enforcement, while other localities refuse to cooperate. Although scholars have examined how sanctuary cities may differ from other places in terms of crime rates, attitudes toward local law enforcement’s collaboration with federal immigration authorities remain understudied. We utilize original data from the 2016 Cooperative Congressional Election Survey (CCES) to study attitudes toward local/federal collaboration. Our results demonstrate that those who most recognize the racial advantage of Whites are significantly less likely to support collaboration between local police and federal authorities. Confirming prior work, our results also support the critical role of partisanship, nativity, and education in explaining attitudes toward sanctuary policies. Our findings have important implications for understanding attitudes toward immigration enforcement and policies.
Analyzing the Economic Sustainability of Tourism Development: Evidence from Hong Kong
Authors: Qiu Hanqin , Fan Daisy X. F. , Lyu Jiaying , Lin Pearl M. C. , Jenkins Carson L.
Published: May 2018

Despite increased concerns about the negative economic impacts of tourism on host communities, insufficient attention has been paid to assess tourism’s economic sustainability. This article aims to develop and validate a framework for assessing economic sustainability from the perspective of local stakeholders. In-depth interviews with 12 major stakeholders and telephone surveys with 1,839 Hong Kong citizens were conducted. The tourism economic sustainability construct consisted of three dimensions: economic positivity, development control, and individual welfare. The reliability and validity of the dimensions were confirmed by the data of subsamples. The links between sociodemographic characteristics and attitudes toward tourism economic sustainability were evaluated. This article enhanced our understanding of tourism economic sustainability by expanding the measurement from the macro-level to the micro-level. Using the study setting in Hong Kong, it transcends previous analyses by providing a context to learn from ongoing controversies about the effects of tourism on the host communities.
Measuring beliefs in the instrumentality of ethnic diversity: Development and validation of the Pro-Diversity Beliefs Scale (PDBS)
Authors: Kauff Mathias , Stegmann Sebastian , van Dick Rolf , Beierlein Constanze , Christ Oliver
Published: May 2018

In general, diversity beliefs are beliefs about the instrumentality of diversity for the functioning of groups. Focusing on a societal level, recent social-psychological research addressed pro-diversity beliefs as individuals’ beliefs that diversity is beneficial for the progress of society. Despite the growing interest in societal pro-diversity beliefs, no systematically validated scale measuring pro-diversity beliefs is available to date. We addressed this shortcoming and studied the reliability and validity of the newly developed Pro-Diversity Beliefs Scale (PDBS) across four samples. Results indicate that the PDBS is reliable, adequately distinct from related and established scales, and valid in predicting external criteria such as outgroup attitudes or intergroup threat.
‘Chance Tourism’: Lucky enough to have seen what you will never see
Authors: Zerva Konstantina
Published: May 2018

The quest for tourist destinations that few have visited, and the experience of a journey that few can share, is becoming even more difficult for those individuals who seek a reputation as tourists. Although this search for authenticity has already been studied, there is still much to be explored. Tourists can enhance their identity as travellers by place attachment with destinations they have visited, and that no longer exist. The fact that these destinations have vanished makes their experiences unrepeatable, turning them into connoisseurs of a gone place. The narration of that past visit enters into a re-interpretation process, especially by those who have not been to these places. Through this transformation of the visit into a chance event, this article shows the connection between chance, tourism and social spatialization. Through a content analysis approach, visitors’ online comments to three tourist sites are used: the World Trade Centre in New York before 9/11, the historical sites of Nepal before the destructive earthquake of 2015 and the ‘Pioneer Cabin Tree’, a giant thousand-year-old sequoia in Calaveras Big Trees State Park, before it was blown down in a storm in 2017.
Lockeans versus nationalists on territorial rights
Authors: Miller David
Published: May 2018

This article examines A. J. Simmons’ Lockean theory of territorial rights and defends the superiority of the rival nationalist theory that he rejects. It begins by arguing that all philosophical accounts of territory need to be supplemented by nonideal theory to address real-world territorial conflicts. Turning to the Lockean theory, it points out that if territorial rights are to emerge from individual property rights in land, such rights must be robust. But on Simmons’ account, individuals only have natural property rights in material things involved in their ongoing purposive activities. Thus, a state founded on such rights would be vulnerable to having neglected parts of its territory expropriated by outsiders. It might also have to downsize in response to population increases elsewhere. Nationalist theories base territorial rights on the collective occupation and transformation of land by groups with shared identities. Three charges against such theories are rebutted: (1) The idea of cohesive national cultures is a myth, in the face of internal cultural diversity. (2) Despite their appeal to history, nationalist theories privilege current possessors of land at the expense of the dispossessed. (3) Such theories cannot solve the problem of ‘trapped minorities’ who don’t share the national identity of the majority.
Comparison of filter smoke number and elemental carbon from thermal optical analysis of marine diesel engine exhaust
Authors: Lappi Maija Kaarina , Ristimäki Jyrki Matias
Published: May 2018

The interest on contribution of shipping to global warming and especially on polar ice melting has increased. The International Maritime Organization is working toward reporting and estimation of black carbon emissions from shipping. The filter smoke number method is discussed as one possible candidate for onboard determination of black carbon/soot concentration of the engine exhaust gas, and it has recently been considered as one of the best candidates for further evaluation in the International Council on Clean Transportation 4th workshop on marine black carbon emission. Proven, standardized technology and small size and simple operation of the filter smoke meter make it a potential choice for actual onboard use. In our study, we evaluated the validity of the filter smoke number method for measuring soot emission by looking at correlations between the filter smoke number and elemental carbon analyzed using thermal optical transmittance analysis. Until now the conversion of the filter smoke number to black carbon /soot emission has been performed with equations derived from high-speed engines operating with distillate fuels. We introduce optimized calculation parameters for filter smoke number to black carbon/soot conversion, which are derived from light and heavy fuel oil measurements. These new parameters can be utilized with improved accuracy for the estimation of the black carbon emission from filter smoke number measurement with marine fuel qualities.
Examining the Psychometric Properties of the SRSS-IE With the Nominal Response Model Within a Middle School Sample
Authors: Moulton Sara E. , Young Ellie L. , Sudweeks Richard R.
Published: May 2018

This study examined the item and category response option functioning of items on the Student Risk Screening Scale for Internalizing and Externalizing Behaviors (SRSS-IE), using item response theory (IRT) methods with a sample of 2,122 middle school students. The SRSS-IE is a screening instrument used to identify students who are potentially at risk for emotional and behavioral disorders (EBD). Utilizing the nominal response and generalized partial credit models of IRT, items from the SRSS-IE were evaluated in terms of the degree to which the response options for each item functioned as intended and how well those response options discriminated among students who exhibited varying levels of EBD risk. Results indicate that the four-response option configuration used in this study may not adequately discriminate regarding the frequency of externalizing and internalizing behaviors demonstrated by middle school students. Recommendations for revising the response options and scoring procedures are discussed.
Mining spatial–temporal motion pattern for vessel recognition
Authors: Sun Lu , Zhou Wei , Guan Jian , He You
Published: May 2018

Approaches of vessel recognition are mostly accomplished by sensing targets and extracting target features, without taking advantage of spatial and temporal motion features. With maritime situation management systems widely applied, vessels’ spatial and temporal state information can be obtained by many kinds of distributed sensors, which is easy to achieve long-time accumulation but are often forgotten in databases. In order to get valuable information from large-scale stored trajectories for unknown vessel recognition, a spatial and temporal constrained trajectory similarity model and a mining algorithm based on spatial and temporal constrained trajectory similarity are proposed in this article by searching trajectories with similar motion features. Based on the idea of finding matching points between trajectories, baseline matching points are first defined to provide time reference for trajectories at different time, then the almost matching points are obtained by setting the spatial and temporal constraints, and the similarity of pairwise almost matching points is defined, which derives the spatial and temporal similarity of trajectories. By searching the matching points from trajectories, the similar motion pattern is extracted. Experiments on real data sets show that the proposed algorithm is useful for similar moving behavior mining from historic trajectories, which can strengthen motion feature with the length increases, and the support for vessel with unknown property is larger than other models.
An end-to-end covert channel via packet dropout for mobile networks
Authors: Tan Yu-an , Xu Xinting , Liang Chen , Zhang Xiaosong , Zhang Quanxin , Li Yuanzhang
Published: May 2018

Voice over Long-Term Evolution enables reliable transmission among enormous Internet of Things devices, by providing end-to-end quality of service for Internet protocol–based services such as audio, video, and multimedia messaging. The research of covert timing channels aims at transmitting covert message stealthily to the receiver using variations of timing behavior. Existing approaches mainly modulate the covert message into inter-packet delays of overt traffic, which are not suitable for Voice over Long-Term Evolution, since most of the inter-packet delays of Voice over Long-Term Evolution traffic are of regular distribution, and any modification on inter-packet delays is easy to be detected. To address the issue, in this work, we propose a novel covert timing channel for the video stream in Voice over Long-Term Evolution, which modulates the covert message by deliberately dropping out video packets. Based on the two-dimensional mapping matrix, the blocks of covert message are mapped into dropout-packet sequence numbers. To recover the covert message, the receiver retrieves the sequence numbers of lost packets and identifies them to be translated into blocks of the covert message. To evaluate our scheme, the simulations with different packet loss rates are conducted to validate the undetectability, throughput, and robustness, finally, the results show that this scheme is effective and reliable.
Indoor positioning system for wireless sensor networks based on two-stage fuzzy inference
Authors: Cheng Chia-Hsin , Yan Yi
Published: May 2018

Wireless indoor positioning systems are susceptible to environmental distortion and attenuation of the signal, which can affect positioning accuracy. In this article, we present a two-stage indoor positioning scheme using a fuzzy-based algorithm aimed at minimizing uncertainty in received signal strength indicator measures from reference nodes in wireless sensor networks. In the first stage, the indoor space is divided into several zones and a fuzzy-based indoor zone-positioning scheme is used to identify the zone in which the target node is located via zone splitting. In the second stage, adaptive trilateration is used to position the target node within the zone identified in the first stage. Simulation results demonstrate that the proposed two-stage fuzzy rectangular splitting outperforms non-fuzzy-based algorithms, including K-Nearest Neighbors–based localization, and traditional triangular splitting schemes. We also developed an expanded positioning scheme to facilitate the selection of a positioning map for large indoor spaces, thereby overcoming the limitations imposed by the size of the positioning area while maintaining high positioning resolution.
Media, communication, and intersectional analysis: ten comments for the International Panel on Social Progress
Authors: Costanza-Chock Sasha
Published: May 2018

This article responds to the International Panel on Social Progress (IPSP) chapter ‘Media, Communication, and the Struggle for Social Progress.’ I argue that in order to advance the IPSP’s goals of progress towards a media system that advances human capabilities, we must name specific forms of structural oppression (what Black feminist scholars call the matrix of domination). I note that the IPSP should develop an intersectional analysis of media representation, employment, and ownership; that online hate speech must be addressed; and that the ‘filter bubble’ critique ignores the importance of subaltern counterpublics, although state and corporate propaganda is indeed a real problem. I urge application of a design justice lens, and identify free software as one important tool. I call attention to media policy proposals by social movements. Finally, I note the development of new tools for media analysis and encourage their application to an intersectional Media Equity Index.
Sexualised drug taking among men who have sex with men: a systematic review
Authors: Tomkins Andrew , George Ryan , Kliner Merav
Published: May 2018

Aims:

Sexualised drug taking is increasingly reported on national and international levels. We aim to review existing evidence of the relationship between recreational drug use (RDU) and sexual intercourse among men who have sex with men (MSM).

Methods:

We reviewed published abstracts and full articles identified from Cochrane, MEDLINE and Embase databases from November 2010 to 2017. We included any existing studies investigating RDU in MSM and at least one of the following: high-risk sexual practices, sexually transmitted infections (STIs) or barriers to accessing specialist support.

Results:

In total, 112 studies were included. Of them, 38 studies specifically reported the prevalence of chemsex-related drug use. Links with sexualised drug taking and high-risk sexual practices including condomless sex and group sex were reported by several studies. Recreational drug use in the sexual setting appears linked to the acquisition of STIs, including hepatitis C, syphilis and gonorrhoea. Reports of adverse mental health outcomes are increasingly described, with several studies documenting chemsex-related inpatient admission. A paucity of research addressing barriers to those accessing specialist drug support services was identified.

Conclusion:

This review demonstrates the complex interplay between recreational drug use, high-risk sexual practices and STIs. It identifies the description of adverse mental health outcomes in the chemsex setting, thus highlighting the need for a multidisciplinary approach across specialties in the management of those adversely affected. Finally, it illuminates the need for future research into perceived barriers of those who require access to support services to ensure timely and comprehensive support provision.
Seven-Year Clinical Surveillance Program Demonstrates Consistent MARD Accuracy Performance of a Blood Glucose Test Strip
Authors: Setford Steven , Grady Mike , Mackintosh Stephen , Donald Robert , Levy Brian
Published: May 2018

Background:

MARD (mean absolute relative difference) is increasingly used to describe performance of glucose monitoring systems, providing a single-value quantitative measure of accuracy and allowing comparisons between different monitoring systems. This study reports MARDs for the OneTouch Verio® glucose meter clinical data set of 80 258 data points (671 individual batches) gathered as part of a 7.5-year self-surveillance program

Methods:

Test strips were routinely sampled from randomly selected manufacturer’s production batches and sent to one of 3 clinic sites for clinical accuracy assessment using fresh capillary blood from patients with diabetes, using both the meter system and standard laboratory reference instrument.

Results:

Evaluation of the distribution of strip batch MARD yielded a mean value of 5.05% (range: 3.68-6.43% at ±1.96 standard deviations from mean). The overall MARD for all clinic data points (N = 80 258) was also 5.05%, while a mean bias of 1.28 was recorded. MARD by glucose level was found to be consistent, yielding a maximum value of 4.81% at higher glucose (≥100 mg/dL) and a mean absolute difference (MAD) of 5.60 mg/dL at low glucose (<100 mg/dL). MARD by year of manufacture varied from 4.67-5.42% indicating consistent accuracy performance over the surveillance period.

Conclusions:

This 7.5-year surveillance program showed that this meter system exhibits consistently low MARD by batch, glucose level and year, indicating close agreement with established reference methods whilste exhibiting lower MARD values than continuous glucose monitoring (CGM) systems and providing users with confidence in the performance when transitioning to each new strip batch.
Job strain and atrial fibrillation – Results from the Swedish Longitudinal Occupational Survey of Health and meta-analysis of three studies
Authors: Fransson Eleonor I , Nordin Maria , Magnusson Hanson Linda L , Westerlund Hugo
Published: May 2018

Background

Knowledge about the impact of occupational exposures, such as work stress, on the risk of atrial fibrillation is limited. The present study aims to investigate the association between job strain, a measure of work stress, and atrial fibrillation.

Design

Prospective cohort study design and fixed-effect meta-analysis.

Methods

Data from the Swedish Longitudinal Occupational Survey of Health (SLOSH) was utilised for the main analysis, combining self-reported data on work stress at baseline with follow-up data on atrial fibrillation from nationwide registers. Cox proportional hazard regression analyses were used to estimate hazard ratios and 95% confidence intervals (CIs). A fixed-effect meta-analysis was conducted to pool the results from the present study with results from two similar previously published studies.

Results

Based on SLOSH data, job strain was associated with an almost 50% increased risk of atrial fibrillation (hazard ratio 1.48, 95% CI 1.00–2.18) after adjustment for age, sex and education. Further adjustment for smoking, physical activity, body mass index and hypertension did not alter the estimated risk. The meta-analysis of the present and two previously published studies showed a consistent pattern, with job strain being associated with increased risk of atrial fibrillation in all three studies. The estimated pooled hazard ratio was 1.37 (95% CI 1.13–1.67).

Conclusion

The results highlight that occupational exposures, such as work stress, may be important risk factors for incident atrial fibrillation.
Cardiac rehabilitation and symptoms of anxiety and depression after percutaneous coronary intervention
Authors: Olsen Siv JS , Schirmer Henrik , Wilsgaard Tom , Bønaa Kaare H , Hanssen Tove A
Published: May 2018

Background

Anxiety and depression are related to coronary heart disease, and psychological support is recommended in cardiac rehabilitation.

Purpose

The aims of this study were: to compare the prevalence of anxiety and depression with respect to cardiac rehabilitation participation among patients who have been treated with percutaneous coronary intervention; to examine prevalence of anxiety and depression among percutaneous coronary intervention patients compared to the general population; and to identify predictors of symptomatic anxiety and depression among percutaneous coronary intervention patients.

Methods

We included 9013 patients undergoing first-time percutaneous coronary intervention. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale in a representative sample of 775 patients at baseline and after three years of follow-up, and in the entire cohort at three-year follow-up.

Results

Cardiac rehabilitation participants had more anxiety and depression than cardiac rehabilitation non-participants at baseline, and both groups had a more anxiety than the general population. The levels of anxiety and depression fell significantly during three years of follow-up, but the changes did not differ between cardiac rehabilitation participants and cardiac rehabilitation non-participants. Three years after percutaneous coronary intervention the prevalence of anxiety was 32% ( p < 0.001), higher among cardiac rehabilitation participants compared to cardiac rehabilitation non-participants. Female gender and younger age were associated with anxiety, whereas older age, lower levels of education and cardiovascular morbidity were associated with depression.

Conclusion

The levels of anxiety and depression were prevalent among percutaneous coronary intervention patients and the levels were not affected by cardiac rehabilitation participation. Anxiety is prevalent among female and younger patients, whereas depression is related to older age and cardiovascular co-morbidity.
The effects of NF-κB signal pathway on the process of anastomotic stricture after the radical resection of esophageal carcinoma
Authors: Cai Hongfei , Li Yang , Wang Rui , Cui Youbin
Published: May 2018

The aim of this article is to identify the relationship between the nuclear factor κB (NF-κB) signal pathway expression and the anastomotic stricture. It particularly focuses on the expression of p65, bcl-2, and cIAP-1 in the anastomotic stricture formation after radical resection of esophageal cancer. A total of 82 esophageal squamous carcinoma patients who had undergone esophagectomy by Ivor Lewis procedure were enrolled in the study. Tissues were collected from the patients who developed the anastomotic stricture after the operation, while para anastomotic tissues served as the control. The protein expression of p65, bcl-2, and cIAP-1 was analyzed by immunohistochemistry and western blot analyses, while the messenger RNA (mRNA) levels of p65, bcl-2, and cIAP-1 were evaluated by reverse transcription polymerase chain reaction (RT-PCR). The results showed that lower expression of p65, bcl-2, and cIAP-1 proteins was observed in the para anastomotic tissue; in the esophageal stricture’s tissue, the expression of these proteins was significantly higher ( P < 0.05). The mRNA levels of P56, bcl-2, and cIAP-1 in the stricture tissue were remarkably increased ( P < 0.05) compared with the para anastomotic tissues, and the mRNA levels in the sample of grade 3 dysphagia were higher ( P < 0.05) than the levels of grade 1 and 2. In the normal esophageal epithelial cell of stricture patients was upregulated compared with that of no stricture patients. We can confirm that the anastomotic stricture has the relationship with the NF-κB signal pathway. The bcl-2 and cIAP-1, located downstream of NF-κB signal pathway, could be a new preventive and therapeutic target for the anastomotic stricture.

Authors: Kerekes Daniel , Goodwin C. Rory , Ahmed A. Karim , Verlaan Jorrit-Jan , Bettegowda Chetan , Abu-Bonsrah Nancy , Sciubba Daniel M.
Published: May 2018

Study Design:

Systematic review.

Objectives:

Sacral chordomas are rare, primary tumors of the spine, best treated with en bloc resection. The purpose of this study was to assess the literature for resected sacral chordoma and to quantify the prevalence of, risk factors for, and treatment outcomes of local and distant recurrence therein.

Methods:

We searched 5 online databases from January 1980 to May 2016 to find articles that report survival, recurrence outcomes, and/or prognostic factors for the resected sacral chordoma patient population. Characteristics and clinical outcomes of the pooled cohort are reported. Fisher exact tests, unpaired t tests, and one-way analysis of variance were used to investigate patient- and treatment-associated prognostic factors for local and distant recurrence. Survival analyses were performed for time to local recurrence and death. The protocol’s PROSPERO ID is CRD42015024384.

Results:

Fifty-seven studies, with 1235 unique sacral chordoma patients, were included in this review. Local and distant recurrence occurred in 42.6% and 22.4% of patients with adequate follow-up, respectively. Kaplan-Meier overall median survival for patients with and without recurrence were 98 and 209 months after surgery, respectively. Wide surgical margin was associated with a lower rate of local recurrence; and wide surgical margin, female sex, and patient age ≥65 years were associated with lower rates of distant recurrence.

Conclusions:

While surgical margin remains the most significant prognostic factor for local and distant recurrence, combined surgical approach may be associated with local recurrence. Male sex and age <65 years may be associated with distant recurrence. Patients with risk factors for recurrence should undergo close monitoring to maximize survival.
State, power and religion in the Indo-Iranian borderlands and North-west India, c. 200 bc–ad 200
Authors: Ghosh Suchandra
Published: May 2018

The Greek tradition of coinage was maintained by the Bactrians, Indo-Greeks, Śakas and Kushanas, ruling successively in the North-west from the second century bc to second century ad. On their coins, apart from the rulers themselves, appear the figures and names of several deities. These were Greek deities in the beginning, to whom Iranian and Indian deities went on being added. The paper traces this process in detail and examines how the rulers first seem to address, through their coins, only an elite Greek or Hellenised aristocracy and then the wider Iranic and Indian populations, through the medium of deities figured on their coins. There was simultaneously the objective of legitimation and glorification of the rulers themselves by the same means. Curiously, Buddhism so important in Gandhara sculpture has only a rare presence on these coins even under the Kushanas.

Failure of education policies in West Bengal, since 1951: An analysis
Authors: Bagchi Amiya Kumar
Published: May 2018

West Bengal, in 1951, was ranked second in the country, with a literacy level of 24.0 per cent, though far behind Kerala with a literacy level of 47.18 per cent. From the very beginning there was an elitist bias in educational planning, so that primary education was badly neglected, and so subsequently West Bengal began to slide in relation to states like Kerala, Maharashtra, Mizoram or Goa. Unfortunately, the elitist bias also persisted during the Left Front rule. As a result, by the time of Census 2011, the literacy level of West Bengal had slid down so far that it was barely above the national average. At the same time, the small state of Tripura, also ruled by a Left Front government, coming up from far behind had caught up with and then had overtaken West Bengal, and was only a little behind Kerala, the most literate state in India. Although this article is supposed to be an account of the state of education in West Bengal since independence it concentrates essentially on the primary school sector, because that is the foundation of all further education. It refers to the Bhabatosh Datta Commission on higher education whose recommendations still remain valid and unfortunately unimplemented.

The Purānas and the making of the cultural territory of Bengal
Authors: Chakrabarti Kunal
Published: May 2018

The article proceeds from the hypothesis that Bengal was peripheral to the main Brahmanical zone, and that many religious beliefs and ritualistic practices existed there, probably in much diversity, before Brahmanism established its dominance. Brahmanism absorbed, modified and unified the local cults. The article takes the cult of the Goddess Maṅgalacaṇḍī as an illustration of how it is specific to Bengal and drew on various local rituals and beliefs in goddesses locally prevalent previously, but now regionalised. The cult as it was being formed was also sought to be accommodated in the Punāṇic framework: thus Bengal was given its particular cults, while preserving its place in the Brahmanical world.
Bhojpuri folk songs of Indians in Fiji
Authors: Basu Raj Sekhar
Published: May 2018

The export of Indian indentured labour to British oversea colonies containing sugar, cotton and indigo plantations began around mid-nineteenth century. One of the destinations was Fiji, the British island colony in the Pacific, to which the Indian labourers, men and women, mainly went from East UP and West Bihar where Bhojpuri was spoken. While archival documents can help us trace the fortunes of individuals, their own feelings and sentiments are best preserved in their songs orally carried from one mouth to another for decades. The earlier songs contain mournful dirges over separation, the misery of those whom they left behind and their own afflictions in Fiji’s harsh white-owned plantations. As the migrations ceased, the Fiji–Indian people’s interest shifted to restoring their connection with Hinduism and its customs, and this has become more prominent in later folk songs. The gender problem (women outnumbered by men) was severe earlier but has now eased as with the passage of generations, the sex ratio has normalised.

The main reason for the erroneous description of tombarthite-(Y) is the result of chemical analyses being carried out on heated material, which removed elements such as C and F. New semi-quantitative chemical analyses show that at least F is present in the fresh material, but absent after a heating scheme identical to that of the original description. Modern powder X-ray diffraction methods (XRD) confirm that the material identified as tombarthite-(Y) is a mixture of metamict and crystalline phases. Consequently, what was known as tombarthite-(Y) is not a mixture of the same minerals in equal amounts in different samples, but mixtures of various minerals depending on the sample. The main minerals identified are thalénite-(Y), xenotime-(Y) and kainosite-(Y). The discreditation of tombarthite-(Y) relies on new analyses of a large number of samples from the collection of the Natural History Museum (NHM) in Oslo and has been approved by the International Mineralogical Association Commission on New Minerals, Nomenclature and Classification (proposal 16-K).
Hydrothermal fluid evolution in the ‘Botro ai Marmi’ quartz-monzonitic intrusion, Campiglia Marittima, Tuscany, Italy. Evidence from a fluid-inclusion investigation
Authors: Fulignati Paolo
Published: May 2018

The quartz-monzonitic intrusion of ‘Botro ai Marmi’ in Tuscany, Italy, can be considered to be a typical example of an intrusion-centred magmatic hydrothermal system. The evolution of hydrothermal fluids in the ‘Botro ai Marmi’ intrusion was investigated using fluid-inclusion analyses to provide suitable physico-chemical constraints on the fluids involved in the late- to post-magmatic hydrothermal activity that affected the intrusion, providing inferences on their origin and variations of temperature and pressure with time.

This work demonstrates that the earliest fluids circulating in the ‘Botro ai Marmi’ intrusion were high-temperature brines exsolved directly from the crystallizing magma. This fluid circulated in the intrusion under lithostatic conditions (P > 90 MPa, T > 540°C). A second evolutionary stage of the magmatic hydrothermal system is marked by the transition from lithostatic (>90 MPa) to hydrostatic dominated conditions (50 to 10 MPa). In this stage the fluids are also interpreted to be mainly orthomagmatic in origin but unmixed in a high-salinity brine and in a low-salinity vapour aqueous phase, at a temperature ranging from ~500 to 300°C. These fluids were responsible for the potassic alteration facies. At a later stage of hydrothermal evolution, abundant meteoric dominated fluids entered the system and are associated with propylitic alteration. This event marks the transition from a magmatic-hydrothermal system to a typical hydrothermal (‘geothermal’) system, which can be assumed to be similar to some extent to the nearby active high-enthalpy geothermal system of Larderello. Low-temperature and low-salinity meteoric water-dominated fluids characterize the latest stage of the ‘Botro ai Marmi’ hydrothermal system.

The new mineral feynmanite, Na(UO2)(SO4)(OH)·3.5H2O, was found in both the Blue Lizard and Markey mines, San Juan County, Utah, USA, where it occurs as a secondary phase on pyrite-rich asphaltum in association with chinleite-(Y), gypsum, goethite, natrojarosite, natrozippeite, plášilite, shumwayite (Blue Lizard) and wetherillite (Markey). The mineral is pale greenish yellow with a white streak and fluoresces bright greenish white under a 405 nm laser. Crystals are transparent with a vitreous lustre. It is brittle, with a Mohs hardness of ~2, irregular fracture and one perfect cleavage on {010}. The calculated density is 3.324 g cm–3. Crystals are thin needles or blades, flattened on {010} and elongate on [100], exhibiting the forms {010}, {001}, {101} and {10$\bar{1}$}, and are up to ~0.1 mm in length. Feynmanite is optically biaxial (–), with α = 1.534(2), β = 1.561(2) and γ = 1.571(2) (white light); 2Vmeas.= 62(2)°; no dispersion; and optical orientation:X=b,Y≈a,Z≈c. It is weakly pleochroic:X= colourless,Y= very pale green yellow andZ= pale green yellow (X<Y<Z). Electron microprobe analyses (WDS mode) provided (Na0.84Fe0.01)(U1.01O2)(S1.01O4)(OH)·3.5H2O. The five strongest powder X-ray diffraction lines are [dobsÅ(I)(hkl)]: 8.37(100)(010), 6.37(33)($\bar{1}$01,101), 5.07(27)($\bar{1}$11,111), 4.053(46)(004,021) and 3.578(34)(120). Feynmanite is monoclinic, has space groupP2/n,a= 6.927(3),b= 8.355(4),c= 16.210(7) Å, β = 90.543(4)°,V= 938.1(7) Å3andZ= 4. The structure of feynmanite (R1= 0.0371 for 1879Io> 2σI) contains edge-sharing pairs of pentagonal bipyramids that are linked by sharing corners with SO4groups, yielding a [(UO2)2(SO4)2(OH)2]2–sheet based on the phosphuranylite anion topology. The sheet is topologically identical to those in deliensite, johannite and plášilite. The dehydration of feynmanite to plášilite results in interlayer collapse involving geometric reconfiguration of the sheets and the ordering of Na.

Background

Thermal imaging is a useful modality for identifying preulcerative lesions (“hot spots”) in diabetic foot patients. Despite its recognised potential, at present, there is no readily available instrument for routine podiatric assessment of patients at risk. To address this need, a novel thermal imaging system was recently developed. This paper reports the reliability of this device for temperature assessment of healthy feet.

Methods

Plantar skin foot temperatures were measured with the novel thermal imaging device (Diabetic Foot Ulcer Prevention System (DFUPS), constructed by Photometrix Imaging Ltd) and also with a hand‐held infrared spot thermometer (Thermofocus® 01500A3, Tecnimed, Italy) after 20 min of barefoot resting with legs supported and extended in 105 subjects (52 males and 53 females; age range 18 to 69 years) as part of a multicentre clinical trial. The temperature differences between the right and left foot at five regions of interest (ROIs), including 1st and 4th toes, 1st, 3rd and 5th metatarsal heads were calculated. The intra‐instrument agreement (three repeated measures) and the inter‐instrument agreement (hand‐held thermometer and thermal imaging device) were quantified using intra‐class correlation coefficients (ICCs) and the 95% confidence intervals (CI).

Results

Both devices showed almost perfect agreement in replication by instrument. The intra‐instrument ICCs for the thermal imaging device at all five ROIs ranged from 0.95 to 0.97 and the intra‐instrument ICCs for the hand‐held‐thermometer ranged from 0.94 to 0.97. There was substantial to perfect inter‐instrument agreement between the hand‐held thermometer and the thermal imaging device and the ICCs at all five ROIs ranged between 0.94 and 0.97.

Conclusions

This study reports the performance of a novel thermal imaging device in the assessment of foot temperatures in healthy volunteers in comparison with a hand‐held infrared thermometer. The newly developed thermal imaging device showed very good agreement in repeated temperature assessments at defined ROIs as well as substantial to perfect agreement in temperature assessment with the hand‐held infrared thermometer. In addition to the reported non‐inferior performance in temperature assessment, the thermal imaging device holds the potential to provide an instantaneous thermal image of all sites of the feet (plantar, dorsal, lateral and medial views).

Background

Despite many preventive measures, outbreaks with multi-drug resistant micro-organisms (MDROs) still occur. Moreover, current alert systems from healthcare organizations have shortcomings due to delayed or incomplete notifications, which may amplify the spread of MDROs by introducing infected patients into a new healthcare setting and institutions. Additional sources of information about upcoming and current outbreaks, may help to prevent further spread of MDROs.

The study objective was to evaluate whether methicillin-resistant Staphylococcus aureus (MRSA) outbreaks could be detected via social media posts or online search behaviour; if so, this might allow earlier detection than the official notifications by healthcare organizations.

Methods

We conducted an exploratory study in which we compared information about MRSA outbreaks in the Netherlands derived from two online sources, Coosto for Social Media, and Google Trends for search behaviour, to the mandatory Dutch outbreak notification system (SO-ZI/AMR). The latter provides information on MDRO outbreaks including the date of the outbreak, micro-organism involved, the region/location, and the type of health care organization.

Results

During the research period of 15 months (455 days), 49 notifications of outbreaks were recorded in SO-ZI/AMR. For Coosto, the number of unique potential outbreaks was 37 and for Google Trends 24. The use of social media and online search behaviour missed many of the hospital outbreaks that were reported to SO-ZI/AMR, but detected additional outbreaks in long-term care facilities.

Conclusions

Despite several limitations, using information from social media and online search behaviour allows rapid identification of potential MRSA outbreaks, especially in healthcare settings with a low notification compliance. When combined in an automated system with real-time updates, this approach might increase early discovery and subsequent implementation of preventive measures.
