‘When housing is provided, but you have only the closet’. Sexual orientation and family housing support in Athens, Greece

ABSTRACT This article explores the impact of sexual orientation on the housing practices of individuals self-identified as LGB+ in Athens, Greece. In Greece, welfare state was always inadequate to cover people’s social needs. On the contrary, the family proved to be resilient as a welfare agent covering also the housing needs of its members by employing related strategies. The support comes ‘with strings attached’, and this includes parents’ demands and wishes upon the lifestyle of the dependent children. These demands have strong gender and sexual connotations imposing a heteronormative life trajectory, which may clash with the desires of LGB+ family members. In order for them to continue receiving support they are ‘pushed’ to employ strategies regarding their ‘coming out’ or sexual identity’s concealment process. In this paper, 16 semi-structured, in-depth interviews were conducted with a double focus: a. the housing pathway of the respondents, and b. the strategic decision of coming out or staying in the closet to benefit from the family welfare.

Topic choices: Revealing concealed processes of curriculum sequencing in English secondary school Music classrooms

AbstractMusic curriculum programmes are designed by English Music teachers in schools as the primary means of musical engagement for young people aged 11–14. Such Music curricula are often structured in learning topics. However, Music teacher rationales for the sequencing of the topics they have chosen to include in their curriculum is an under‐developed area of music education research literature. This study seeks to examine teacher practices in this domain through a comparative case study of nine English secondary school teachers using Think Aloud Protocols to uncover sequencing practices. The findings are analysed using the Friedman ANOVA statistical test and eyeball analysis of teacher curriculum formulations. Theorising from these results facilitated the development of a teacher model of curriculum processing, and illuminated hidden practices in curriculum design.

Spatial and Frequency Approaches for Audio File Protection

In order to protect audio files, we propose in this paper a new integration scheme for blind audio file watermarking. The goal is to find a compromise between capacity and imperceptibility in order to hide as much data as possible while minimizing file degradation. This integration scheme is implemented in the three insertion domains: spatial, frequency and multi-resolution domains. For the spatial-domain integration, the mark is inserted directly into the data samples. For the frequency-domain integration, a Discrete Cosine Transform is applied to the audio frames; after the thresholding and quantification step, the watermark is inserted into the Discrete Cosine Transform coefficients to obtain the watermarked file. For the multi-resolution-domain insertion, a single-level Discrete Wavelet Transform is applied using the scaling low-pass filter and wavelet high-pass filter. The watermark integration is then performed using the obtained AC coefficients. The proposed concealment process combines three values to integrate two bits and only one may be modified, which reduces the probability of change unlike other approaches. This implies less modification and therefore less distortion of the host file; this explains the good Signal-to-Noise Ratio obtained of more than 59[Formula: see text]dB for the spatial-domain integration and therefore a reasonable imperceptibility. An evaluation of the watermark’s robustness demonstrates that the proposed schemes generate reasonably robust watermarked samples against various attacks with a high-quality watermark with normalized cross-correlation greater than 0.9 for the three insertion domains.

El Muntu en la literatura contemporánea: filosofía de la fuerza vital en Fe en disfraz (2009) de Mayra Santos-Febres

En Fe en disfraz (2009), de Mayra Santos Febres (1966), la autora presenta una representación de la espiritualidad ancestral que puede considerarse Muntu. Esta filosofía está constituida por diferentes maneras de concebir el mundo. A pesar de que, al arribo de las personas esclavizadas a América se transformara en un proceso de ocultamiento y sincretismo constante, el Muntu permanece de varias maneras en los pueblos negros de las Américas, principalmente del Caribe. Una de aquellas maneras es la fuerza vital, y leer Fe en disfraz desde este pensamiento nos permite comprenderla. Para desarrollar lo que afirmo, analizaré la ritualización que Fe Verdejo realiza en el acto de uso del vestido de la esclava Xica (Chica) da Silva, que, bajo la cosmovisión del Muntu y la perspectiva de la filosofía de la fuerza vital, crea en su propio cuerpo un canal de comunicación ancestral que expone la violencia con que se ha construido la identidad afrocaribeña.

EFFECTS OF POSTURAL EDUCATION IN ELEMENTARY SCHOOL CHILDREN: A SYSTEMATIC REVIEW.

ABSTRACTObjective: To determine the effect of postural education on the learning and postural habits of elementary school children without physical intervention.Methods: We searched PubMed, Lilacs, SciELO, Cochrane, and Science Direct data bases and reference lists of studies in February 2020. The eligibility criteria were randomized clinical trials related to the effect of postural education in children aged between 6 and 12 years old. Two authors independently assessed trials for inclusion and risk of bias: randomization process, deviations from intended interventions, missing outcome data, measurement of the outcome, and selection of the reported result. Data were extracted in standardized tables including information on author, publication year, country, sample size, age, sex, intervention characteristics, outcome measurements and results.Results: We found seven clinical trials (involving 2,568 children) for the review. The studies were conducted between 2000 and 2018: four in Belgium, two in Spain, and one in Germany. All seven included trials underwent evaluation: only one had a clear process of randomization and allocation concealment. All included studies were judged as having high risk of bias in at least one domain or have concerns for multiple domains.Conclusions: The positive effects of acquired knowledge and postural habits found in the studies cannot be used to reliably support postural education in elementary school children due to a high risk of bias in the evaluated studies.

Luminescent monomeric and dimeric Ru(ii) acyclic carbene complexes as selective sensors for NH3/amine vapor and humidity.

A new class of luminescent bis(bipyridyl) Ru(ii) pyridyl acyclic carbene complexes with environmentally-sensitive dimerization equilibrium have been developed. Owing to the involvement of the orbitals of the diaminocarbene ligand in the emissive excited state, the phosphorescence properties of these complexes are strongly affected by H-bonding interactions with various H-bonding donor/acceptor molecules. With the remarkable differences in the emission properties of the monomer, dimer, and H-bonded amine adducts together with the change of the dimerization equilibrium, these complexes can be used as luminescent gas sensors for humidity, ammonia, and amine vapors. With the responses to amines and humidity and the corresponding change in the luminescence properties, a proof-of-principle for binary optical data storage with a reversible concealment process has been described.

Influence of different concealment conditions of parallel double flaws on mechanical properties and failure characteristics of brittle rock under uniaxial compression

Previous 2D studies and tests have mainly focused on the discontinuity of fracture structures along the flaw-inclination direction, and there has been little research into the discontinuity or concealment characteristics of flaws along the flaw-strike direction. To this end, hard brittle rock-like gypsum specimens containing two parallel flaws with three types of flaw-concealment conditions (with proportions of 3D internal flaws of 0%, 50%, and 100%) were prepared. Uniaxial compression tests, accompanied by digital image correlation and acoustic emission monitoring, revealed the following. 1) The concealment conditions of the parallel flaws mainly influenced the uniaxial compression strength of the samples, while the existence of fracture structures was the main factor affecting their elastic modulus. 2) The flaw-concealment conditions had a significant effect on the distributions of the external and internal secondary failure structures. 3) When the proportion of 3D internal flaws was 50%, local failures occurred around the internal flaws and remained hidden, never showing on the outside surface of the specimen; when the proportion of 3D internal flaws was 100%, this kind of 3D sample had greater strength, a faster failure process, more severe damage behaviors, and a more concealed process of destruction than the corresponding 2D sample. 4) The higher strength and concealed failure process of samples containing 3D internal flaws explains why the conclusions of previous 2D research have been found to be not applicable to real 3D conditions.

Improved technique for hiding data in a colored and a monochrome image

Find a new way to hide the different types of confidential and important text files inside the images without noticing any change or distortion of the information in the images after the process of concealment or attempt to be detected by hackers. And then extract these texts and retrieved on demand without loss or loss or distortion of any of its content. The algorithm was used to hide the different text in different image formats using (256) elements, monochrome and color where about 4500 characters were hidden in a monochrome image and about 900 characters in a color image and with a hiding distance (S) where N = 3, key = 3. The overall error rate is low (0.05-0.17) and no distortions were observed on the resulting image

Conflictos territoriales y culturales en la renovación del frente costero, Rosario (Argentina)

Este trabajo reconstruye el proceso de ocupación, desalojo y desposesión de dos experiencias de producción de espacio urbano en una ciudad del Sur Global: Rosario (Argentina). Nos centramos en la franja urbana de la costa central, escenario de las trayectorias de dos sujetos colectivos, los okupas y los pescadores artesanales. Ambas comunidades presentaron formas alternativas de producir e imaginar el espacio urbano y plantearon la necesidad de generar diferencias con las tendencias corporativas que mercantilizaban la ciudad, su cultura y sus modos de vida. A través de sus prácticas y resistencias cotidianas, okupas y pescadores mostraron alternativas espaciales y futuros culturales-productivos para una genealogía y cartografía del presente urbano. Mediante una combinación de la hermenéutica etnográfica e historiográfica, intentamos mostrar las prácticas de resistencia a las fórmulas gubernamentales de la renovación urbana.

New protocols of cognitive data management and sharing in cloud computing

SummaryIn this paper, we shall discuss new classes of cognitive systems dedicated the tasks of dividing and managing shared information not only in simple horizontal structures but also primarily in vertical structures. An example of such a structure is a computer cloud where, from various levels of access to information, one can execute the management process, both with respect to the entire information resources, as well as to individual pieces of data, including shared information. A special type of information is a service, which, similar to various types of data, is subject to the concealment process. In this work, we shall present universal algorithms for shared data management, such that can be used in concealment protocols both for data and services. Due to the above, this paper will treat the term “service” as a special type of data, constituting the basis of their sharing and management processes. Moreover, we shall determine the impact of the proposed algorithms on the enhancement of data/service management processes in Cloud Computing as well as the impact of the service management and data sharing processes in Could Computing on decision‐taking processes in systems supporting the management processes.

Hide or Seek? Physiological Responses Reflect Both the Decision and the Attempt to Conceal Information

The process of information concealment is more relevant than ever in this day and age. Using a modified concealed-information test (CIT), we aimed to unmask this process by investigating both the decision and the attempt to conceal information in 38 students. The attempt to conceal (vs. reveal) information induced a differential physiological response pattern within subjects—whereas skin conductance increased in both conditions, respiration and heart rate were suppressed only in the conceal condition—confirming the idea that these measures reflect different underlying mechanisms. The decision to conceal (vs. reveal) information induced enhanced anticipatory skin conductance responses. To our knowledge, this is the first study that observed such anticipatory responses in an information-concealment paradigm. Together, these findings imply that our physiological responses reflect, to some degree, both the decision and the attempt to conceal information. In addition to strengthening CIT theory, this knowledge sheds novel light on anticipatory responding in decision making.

Pojęcie sztuki i działa sztuki w teorii sztuki i konserwacji

At all times, art has quickly responded to the evident and concealed socio-political processes in the society. Starting from the first decades of the twentieth century, the semantic meaning of the terms “art” and “work of art” gradually has changed; art does not always refer to the category of beauty, and therefore the criteria for the selection of artefacts to works of art also has changed. The transformation of the phenomenon into art occurs gradually: first it arises spontaneously, then specific genres and professionals appear, then it becomes a social pheno­menon and holds a particular niche in the cultural life of society. So, art should be a means of educating society, which develops according to the laws of aesthetics and composition, and in this case, the elemental phenomenon becomes an artistic phenomenon. The restoration industry is quite conservative; it adheres to the criteria for defining a work of art and the basics of preserving and reproducing a work of art that developed during the 20th and 21st centuries, in

Quality enhancement with fault tolerant embedding in video transmission over WMSNs in 802.11e WLAN

With the ever-growing demand in video transmissions, it is essential to design an efficient compression and powerful transmission scheme to transmit a large volume of data in wireless multimedia sensor networks (WMSNs). The main objective of this work is to maximize the network throughput and to maintain/support a better visual experience to different end-users. In this paper, we propose a predictive compression with fault-tolerant embedding based multi-path routing and concealment process to maintain the Quality of Service (QoS) and Quality of Experience (QoE) in video transmission. In order to reduce the bit rate in high-efficiency videos, a Scalable High-efficiency Inter-layer Prediction based Video coding (SHIPVC) is proposed with two layer predictions such as texture color, and motion with different quantization parameters to attain the high coding efficiency. After compression, a multi-path genetic algorithm establishes a routing and fault tolerance embedding during transmission to maintain the QoS. In decoding side, QoE is maintained by concealing the Intra frame (I-frame) and Predicted frame (P-frame) separately using the motion vector estimation. Experimental results show better performances through bit rate reduction, maximum fault tolerance, and minimum delay parameters. The PSNR calculation for concealment technique shows the better result when compared to the previous standards. Hence, the proposed method performs the effective video transmission with acceptable quality measurements in WMSNs.

Effectiveness of a healthy lifestyle intervention for chronic low back pain: a randomised controlled trial.

We assessed the effectiveness of a 6-month healthy lifestyle intervention, on pain intensity in patients with chronic low back pain who were overweight or obese. We conducted a pragmatic randomised controlled trial, embedded within a cohort multiple randomised controlled trial of patients on a waiting list for outpatient orthopaedic consultation at a tertiary hospital in NSW, Australia. Eligible patients with chronic low back pain (>3 months in duration) and body mass index ≥27 kg/m and <40 kg/m were randomly allocated, using a central concealed random allocation process, to receive advice and education and referral to a 6-month telephone-based healthy lifestyle coaching service, or usual care. The primary outcome was pain intensity measured using an 11-point numerical rating scale, at baseline, 2 weeks, and monthly for 6 months. Data analysis was by intention-to-treat according to a prepublished analysis plan. Between May 13, 2015, and October 27, 2015, 160 patients were randomly assigned in a 1:1 ratio to the intervention or usual care. We found no difference between groups for pain intensity over 6 months (area under the curve, mean difference = 6.5, 95% confidence interval -8.0 to 21.0; P = 0.38) or any secondary outcome. In the intervention group, 41% (n = 32) of participants reported an adverse event compared with 56% (n = 45) in the control group. Our findings show that providing education and advice and telephone-based healthy lifestyle coaching did not benefit patients with low back pain who were overweight or obese, compared with usual care. The intervention did not influence the targeted healthy lifestyle behaviours proposed to improve pain in this patient group.

Exercise-based cardiac rehabilitation for adults with stable angina.

A previous Cochrane review has shown that exercise-based cardiac rehabilitation (CR) can benefit myocardial infarction and post-revascularisation patients. However, the impact on stable angina remains unclear and guidance is inconsistent. Whilst recommended in the guidelines of American College of Cardiology/American Heart Association and the European Society of Cardiology, in the UK the National Institute for Health and Care Excellence (NICE) states that there is "no evidence to suggest that CR is clinically or cost-effective for managing stable angina". To assess the effects of exercise-based CR compared to usual care for adults with stable angina. We updated searches from the previous Cochrane review 'Exercise-based cardiac rehabilitation for patients with coronary heart disease' by searching the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, DARE, CINAHL and Web of Science on 2 October 2017. We searched two trials registers, and performed reference checking and forward-citation searching of all primary studies and review articles, to identify additional studies. We included randomised controlled trials (RCTs) with a follow-up period of at least six months, which compared structured exercise-based CR with usual care for people with stable angina. Two review authors independently assessed the risk of bias and extracted data according to the Cochrane Handbook for Systematic Reviews of Interventions. Two review authors also independently assessed the quality of the evidence using GRADE principles and we presented this information in a 'Summary of findings' table. Seven studies (581 participants) met our inclusion criteria. Trials had an intervention length of 6 weeks to 12 months and follow-up length of 6 to 12 months. The comparison group in all trials was usual care (without any form of structured exercise training or advice) or a no-exercise comparator. The mean age of participants within the trials ranged from 50 to 66 years, the majority of participants being male (range: 74% to 100%). In terms of risk of bias, the majority of studies were unclear about their generation of the randomisation sequence and concealment processes. One study was at high risk of detection bias as it did not blind its participants or outcome assessors, and two studies had a high risk of attrition bias due to the numbers of participants lost to follow-up. Two trials were at high risk of outcome reporting bias. Given the high risk of bias, small number of trials and participants, and concerns about applicability, we downgraded our assessments of the quality of the evidence using the GRADE tool.Due to the very low-quality of the evidence base, we are uncertain about the effect of exercise-based CR on all-cause mortality (risk ratio (RR) 1.01, 95% confidence interval (CI) 0.18 to 5.67; 195 participants; 3 studies; very low-quality evidence), acute myocardial infarction (RR 0.33, 95% CI 0.07 to 1.63; 254 participants; 3 studies; very low-quality evidence) and cardiovascular-related hospital admissions (RR 0.14, 95% CI 0.02 to 1.1; 101 participants; 1 study; very low-quality evidence). We found low-quality evidence that exercise-based CR may result in a small improvement in exercise capacity compared to control (standardised mean difference (SMD) 0.45, 95% CI 0.20 to 0.70; 267 participants; 5 studies, low-quality evidence). We were unable to draw conclusions about the impact of exercise-based CR on quality of life (angina frequency and emotional health-related quality-of-life score) and CR-related adverse events (e.g. skeletomuscular injury, cardiac arrhythmia), due to the very low quality of evidence. No data were reported on return to work. Due to the small number of trials and their small size, potential risk of bias and concerns about imprecision and lack of applicability, we are uncertain of the effects of exercise-based CR compared to control on mortality, morbidity, cardiovascular hospital admissions, adverse events, return to work and health-related quality of life in people with stable angina. Low-quality evidence indicates that exercise-based CR may result in a small increase in exercise capacity compared to usual care. High-quality, well-reported randomised trials are needed to assess the benefits and harms of exercise-based CR for adults with stable angina. Such trials need to collect patient-relevant outcomes, including clinical events and health-related quality of life. They should also assess cost-effectiveness, and recruit participants that are reflective of the real-world population of people with angina.

CRIME METHOD IN THE SPHERE OF ECONOMIC ACTIVITY AS SYSTEM-FORMING ELEMENT OF CRIMINALISTICS DESCRIPTION

The problem questions of criminalistic interrelations of the crime method in sphere of economic activities with other elements of criminalistic characteristic (a subject of a criminal infringement, personality of a criminal, typical traces) are studied. Depending on circumstances, key value when investigating crimes in the sphere of economic activity may have any from the specified elements of the criminalistic characterictics. The analysis of investigative and judicial practice shows that there exist correlation dependences between such structural elements of a criminalistic characteristic of crimes in the sphere of economic activity as their method, typical traces and criminal personalities because the type and the method of a crime are in a close relation with the criminal personality. But as this research and investigative practice proves, for this type of crimes the method occupies a special, leading position. It’s a system-forming element of a criminalistic characteristic which is related with the other dependences of high degree ofprobability. It’s explained by that a method is most informative, and in it (by means of it) all components of process of preparation, fulfillment and crime concealment in the sphere of economic activity are fully displayed. The crimes methods study is a source for the newest recommendations on struggle against crime. The data about this criminalistic category is used for working out tactical means and methodical recommendations about disclosure, investigation and the prevention of crimes in the sphere of economic activity and also for the organization and planning of investigation. In particular, the information about the methods of crimes is used for providing comprehensiveness, all-roundness and efficiency of investigation; for search of the persons who have committed a crime, and also for the prevention from their committing by already known methods or by such that could appear.

A new computing environment for collective privacy protection from constrained healthcare devices to IoT cloud services

The Internet of healthcare things is essentially a new model that changes the way of the delivery and management of healthcare services. It utilizes digital sensors and cloud computing to present a quality healthcare service outside of the classical hospital environment. This resulted in the emergence of a new class of online web 4.0 services, which are termed “cloud healthcare services”. Cloud healthcare services offer a straightforward opportunity for patients to communicate with healthcare professionals and utilize their personal IoHT devices to obtain timely and accurate medical guidance and decisions. The personal IoHT devices integrate sensed health data at a central cloud healthcare service to extract useful health insights for wellness and preventive care strategies. However, the present practices for cloud healthcare services rely on a centralized approach, where patients’ health data are collected and stored on servers, located at remote locations, which might be functioning under data privacy laws somewhat different from the ones applied where the service is running. Promoting a privacy respecting cloud services encourages patients to actively participate in these healthcare services and to routinely provide an accurate and precious health data about themselves. With the emergence of fog computing paradigm, privacy protection can now be enforced at the edge of the patient’s network regardless of the location of service providers. In this paper, a framework for cloud healthcare recommender service is presented. We depicted the personal gateways at the patients’ side act as intermediate nodes (called fog nodes) between IoHT devices and cloud healthcare services. A fog-based middleware will be hosted on these fog nodes for an efficient aggregation of patients generated health data while maintaining the privacy and the confidentiality of their health profiles. The proposed middleware executes a two-stage concealment process that utilizes the hierarchical nature of IoHT devices. This will unburden the constrained IoHT devices from performing intensive privacy preserving processes. At that, the patients will be empowered with a tool to control the privacy of their health data by enabling them to release their health data in a concealed form. The further processing at the cloud healthcare service continues over the concealed data by applying the proposed protocols. The proposed solution was integrated into a scenario related to preserving the privacy of the patients’ health data when utilized by a cloud healthcare recommender service to generate health insights. Our approach induces a straightforward solution with accurate results, which are beneficial to both patients and service providers.

Activation characteristics analysis on concealed fault in the excavating coal roadway based on microseismic monitoring technique

In order to effectively monitor the concealed fault activation process in excavation activities, based on the actual condition of a working face containing faults with high outburst danger in Xin Zhuangzi mine in Huainan, China, we carried out all-side tracking and monitoring on the fault activation process and development trend in excavation activities by establishing a microseismic monitoring system. The results show that excavation activities have a rather great influence on the fault activation. With the working face approaching the fault, the fault activation builds up and the outburst danger increases; when the excavation activities finishes, the fault activation tends to be stable. The number of microseismic events are corresponding to the intensity of fault activation, and the distribution rules of microseismic events can effectively determine the fault occurrence in the mine. Microseismic monitoring technique is accurate in terms of detecting geologic tectonic activities, such as fault activations lying ahead during excavation activities. By utilizing this technique, we can determine outburst danger in excavation activities in time and accordingly take effective countermeasures to prevent and reduce the occurrence of outburst accidents.

Time Delay Concealment in Feedback Chaotic Systems With Dispersion in Loop

The concealment of time delay signature is one of the most critical issues in delayed-feedback optical chaotic systems. In this paper, we present a method to address this problem without significantly complicating the original architecture. By properly introducing a dispersion module into the feedback loop, a different frequency component of chaotic spectrum will be subject to different time delay in feedback loop, thus destroying the generation mechanism of time delay signature (TDS). The concealment performance is verified by both time-domain and spectrum analysis methods. The relation between the amplitude of TDS and cavity dispersion value is evaluated in detail. Since the dispersion module has no filtering effect, the chaotic bandwidth will not be affected during the TDS concealment process. This proposal solves the security problem of feedback chaotic systems without introducing much extra effort in implementation, and the underlying principle is not restricted to all-optical chaotic systems but applies for other optelectrical chaotic dynamics, which include a feedback cavity.

Male-Partnered Sexual Minority Women: Sexual Identity Disclosure to Health Care Providers During the Perinatal Period.

Male-partnered sexual minority women (SMW) have received little research attention, despite the fact that they represent a large proportion of SMW - particularly child-bearing SMW. Male-partnered SMW are less "out" than female-partnered SMW and will likely be "read" as heterosexual by perinatal providers. Given this, and evidence that pregnant women have unique mental health care needs, the current study focuses on male-partnered SMW (n = 28) during the perinatal period, recruited from Toronto, Canada and Massachusetts, USA, in an effort to understand disclosure and concealment processes in general and to perinatal heath care providers specifically. Women generally reported that they did not disclose (but made no effort to conceal) their sexual identities and histories in new or unfamiliar relationships, largely because the topic rarely came up, although some women highlighted bisexual invisibility and fear of biphobia as reasons for non-disclosure. Despite overall positive experiences with perinatal providers, less than one-quarter of the sample (n = 6) had disclosed their sexual identities and histories to them. Most women felt that this information was generally not relevant to their health care, and particularly their reproductive/obstetric care, although some believed that disclosure would be appropriate under conditions of sexual health risk (n = 8). Others noted that although they did not feel the need to disclose, they did prefer an LGBQ-affirming provider (n = 7). Findings provide insight into male-partnered SMW's views and patterns of disclosure during the perinatal period, and have implications for providers, organizations, and scholars who interface with SMW. Pregnant sexual minority women with male partners are often assumed to be heterosexual, raising questions about whether and when these women disclose their sexual minority status in the perinatal context. This qualitative study of 28 women found that most participants did not share their sexual identity or sexual histories with their perinatal health care providers because this information was perceived as not relevant to their care, although some women nevertheless valued having LGBTQ friendly providers.
