Implications of participatory methods to address mental health needs associated with climate change: ‘photovoice’ in Nepal
Authors: MacFarlane Elizabeth K. , Shakya Renu , Berry Helen L. , Kohrt Brandon A.
Published: January 2018

‘Photovoice’, a community-based participatory research methodology, uses images as a tool to deconstruct problems by posing meaningful questions in a community to find actionable solutions. This community-enhancing technique was used to elicit experiences of climate change among women in rural Nepal. The current analysis employs mixed methods to explore the subjective mental health experience of participating in a 4- to 5-day photovoice process focused on climate change. A secondary objective of this work was to explore whether or not photovoice training, as a one-time 4-to 5-day intensive intervention, can mobilise people to be more aware of environmental changes related to climate change and to be more resilient to these changes, while providing positive mental health outcomes.

Reconciliation and psychiatry in South Africa
Authors: van Rensburg Bernard Janse
Published: January 2018

Although psychiatrists did not form part of the structures of the South African Truth and Reconciliation Commission (TRC), the Society of Psychiatrists of South Africa (SPSA) at the time did make a submission. Since then, the local association of psychiatrists has been reconstituted as the South African Society of Psychiatrists (SASOP). Psychiatry and psychiatrists may have to extend their activities beyond rehabilitation and restoration, to include endeavours to prevent future violations of human rights.
Mental health law in Bolivia
Authors: Aboaja Anne , Arroyo Guillermo Rivera , Grant Liz
Published: January 2018

Bolivia's mental health plan is not currently embedded in mental health legislation or a legal framework, though in 2014 legislative change was proposed that would begin to provide protection and support for the hospital admission, treatment and care of people with mental disorders in Bolivia. Properly resourced, regulated and rights-based mental health practice is still required. Mental healthcare in the primary care setting should be prioritised, and safeguards are needed for the autonomy of all patients, including all those in vulnerable and cared-for groups, including those in prisons.
Coercion in mental healthcare: time for a change in direction
Authors: Molodynski Andrew , Khazaal Yasser , Callard Felicity
Published: January 2018

Coercion has always been integral to the care and treatment of people who are mentally ill and there is no ‘perfect’ model in which coercion is absent. A number of interventions have shown promise in reducing the use of coercion, however, and we believe the evidence points to ways forward that may improve both the experience and the outcome of care.

Mental health services for asylum seekers and refugees: a snapshot
Authors: Briffa Katy
Published: January 2018

As fellow human beings uproot their lives in search of protection, and for those who survive to reach European shores, many countries are faced with an unprecedented, highly complex challenge of managing huge and immediate need. Clearly, immigration agencies are front line in this scenario, but they are closely followed by accommodation, subsistence, community and health agencies. It is widely recognised that the mental health burden of asylum seekers is large and the stir of growing interest at a clinical level in addressing that burden is encouraging. Mental health services have been aware of asylum seekers and refugees for decades but we have grappled with our role, been confused by the relevance of a political dimension and overwhelmed with how to manage diverse need, in the face of endless competing demands. Mental health services for asylum seekers and refugees have largely evolved in many and varied ways, dependent on local need and interest.
Mental health law in India: origins and proposed reforms
Authors: Firdosi Muhammad Mudasir , Ahmad Zulkarnain Z.
Published: January 2018

Although mental health legislation has existed in India since the mid-19th century, it has gone through various changes over the years and the Mental Health Care Bill 2013 has generated a lot of debate and criticism. Despite its shortcomings, the general expectation is that this bill will usher in a new era of proper care and allow people with mental disorders to lead a dignified life.
Mental health law in Pakistan
Authors: Tareen Amina , Tareen Khalida Ijaz
Published: January 2018

Continued efforts to produce appropriate mental health legislation in Pakistan led to the Mental Health Ordinance of 2001. However, with the 18th amendment to the constitution and devolution of health responsibilities to the provincial governments, it became the task of the provinces to pass appropriate mental health legislation through their respective assemblies. Currently the mental health legislative picture is fragmented and unsatisfactory. Only the provinces of Sindh and Punjab have a mental health act in place and there is an urgent need for similar legislative frameworks in other provinces to protect the rights of those with mental illness.
Mental health services in Libya
Authors: Rhouma Abdul Hakim , Husain Nusrat , Gire Nadeem , Chaudhry Imran Bashir
Published: January 2018

Despite all the internal and external criticisms of mental health services in Libya, they remain underdeveloped across the country. The World Health Organization has made efforts to improve the country's mental health services; however, until a stable government is formed, patients with mental illness will continue to be deprived of their basic needs.

Forensic psychiatric service provision in Pakistan and its challenges
Authors: Hassan Tariq , Nizami Asad Tamizuddin , Asmer M. Selim
Published: January 2018

In the Islamic Republic of Pakistan the law relating to people who are mentally ill, until 2001, was set out by the Lunacy Act of 1912, which was inherited from the British colonial occupiers. In 2001 the Mental Health Ordinance 2001 took its place but only for this federal law to be superseded in April 2010 with the 18th constitutional amendment. As part of that amendment, provinces have become responsible for (psychiatric) healthcare, including mental health legislation. Forensic psychiatry is practised in Pakistan but is very much in its infancy; it needs to develop and learn from more experienced countries in Europe and North America. Cultural factors and misconceptions arising from religion can at times contribute to, or create, barriers to the implementation of forensic psychiatric services in Pakistan. This paper reviews the current state of forensic psychiatric services in Pakistan and is intended to open the debate on the challenges ahead.
Listening to silence – trauma and recovery in post-golpe Chile
Authors: Kent Lindsey
Published: January 2018

I visited Chile for the first time in 2003. Over the course of the 12 months during which the country became my home, I realised there was a secret side to the capital city, Santiago. Never was this clearer than when I witnessed a demonstration to mark the 30th anniversary of the 11 September 1973 coup, when General Pinochet took power. I watched tears stream down the cheeks of men and women as they sang along with the revolutionary Cuban folk singer Silvio Rodriguez, raising their fists in the air. I felt the distrust of and anger towards the police who lined rooftops with snipers and the military units which filled side streets with water cannons. It was a visceral experience, made more so by the contrast with day-to-day life on the city's streets. This was a boom town, proud of its malls and economic growth, and the residents of Santiago made every effort to remark upon their high standards of living.
Hierarchical genetic interactions between FOXG1 and LHX2 regulate the formation of the cortical hem in the developing telencephalon
Authors: Godbole Geeta , Shetty Ashwin S. , Roy Achira , D'Souza Leora , Chen Bin , Miyoshi Goichi , Fishell Gordon , Tole Shubha
Published: January 2018

During forebrain development, a telencephalic organizer called the cortical hem is crucial for inducing hippocampal fate in adjacent cortical neuroepithelium. How the hem is restricted to its medial position is therefore a fundamental patterning issue. Here, we demonstrate that Foxg1-Lhx2 interactions are crucial for the formation of the hem. Loss of either gene causes a region of the cortical neuroepithelium to transform into hem. We show that FOXG1 regulates Lhx2 expression in the cortical primordium. In the absence of Foxg1, the presence of Lhx2 is sufficient to suppress hem fate, and hippocampal markers appear selectively in Lhx2-expressing regions. FOXG1 also restricts the temporal window in which loss of Lhx2 results in a transformation of cortical primordium into hem. Therefore, Foxg1 and Lhx2 form a genetic hierarchy in the spatiotemporal regulation of cortical hem specification and positioning, and together ensure the normal development of this hippocampal organizer.

Anatomy and physiology, 5. The musculoskeletal system
Authors: Peate Ian
Published: January 2018

This article considers the musculoskeletal system, which provides form, support, stability, and movement to the body. It is made up of the bones, muscles, cartilage, tendons ligaments and joints. Every bone is a complex living organ that is made up of a number of cells, protein fibres and minerals. The axial and appendicular skeleton are outlined, the types of bones are described, as are the joints. Other functions of the skeleton, such as its role in blood formation, how it stores various types of substances to encourage growth and repair of the body, are also discussed.

The muscles of the muscular system keep bones in place, assisting with movement by contracting and pulling on the bones. The joints allow motion: different bones are connected by joints, which in turn are connected to other bones and muscle fibres via connective tissues, such as tendons and ligaments. The cartilage prevents the bone ends from rubbing directly on each other.

The healthcare assistant and assistant practitioner (HCA and AP) should have an understanding of the skeletal system as they offer care to a variety of patients across the lifespan. A glossary of terms is provided at the end of the article, along with a short quiz.

Authors: Hunter Ann
Published: January 2018

Skill-mix issues involve task analysis, interprofessional roles and the use of unqualified staff. An attempt has to be made to match skill to needs. This article explores the concepts of need and demand and discusses how the professions can take the responsibility for clarifying their roles, using unqualified staff and positively investigating the role of generic therapists and helpers.
Improving the links: field work educators’ conferences
Authors: Walker Elizabeth M
Published: January 2018

The change from diploma to degree courses in undergraduate physiotherapy education means that courses offered by schools of physiotherapy differ much more than in the past. This has increased the need for good communication between the academic (school) units and the fieldwork units where students gain their clinical experience. This article discusses the reasons why such communication is important and how communication may be facilitated by the introduction of fieldwork educators’ conferences.
Personal safety for disabled people: a consultative exercise

Physiotherapy research: finding out how it works
Authors: Woledge Roger C
Published: January 2018

It is often said that physiotherapy is not sufficiently supported by research, which is one reason why, in an era of intense competition for resources, these treatments may become less available to patients. This widely held opinion may well be correct, although I know of no measurement of research output that can prove it; so what should be done? One step would be to carry out more research into the outcomes of physical therapy, comparing the results to those patients receiving less or no treatment or to those results obtained with alternative types of treatment. There is certainly a role for such studies in better quantifying and optimising the cost-effectiveness of physical therapy, and then in convincing management of the relative cost-effectiveness of what the therapist can offer.
Lorna: a family's adaptation

Barbara Bray: A champion of French ‘New Novelists’ on British radio
Authors: Landfried Carrie C.
Published: January 2018

This article examines the role played by Barbara Bray in the selection, adaptation, translation and, occasionally, production of works by French New Novelists on the BBC’s Third Programme starting in the late 1950s. Bray worked tirelessly to promote these francophone avant-garde authors, including Michel Butor, Marguerite Duras, Claude Mauriac, Claude Ollier, Robert Pinget, Alain Robbe-Grillet and Nathalie Sarraute. She was particularly passionate about the work of Duras and Pinget, with whom she maintained a professional relationship as their translator even after leaving the BBC. A study of samples of Duras and Pinget’s radiophonic adaptations illustrates Bray’s talents. Although the results of her efforts were mixed as some authors and texts were rejected by the British radio giant, she helped expose audiences to important experimental works, all while encouraging certain writers to more fully explore the radiophonic affinities of their art.
Growth of Aechmea fasciata plants in function of substrate base saturation and fertirrigation methods
Authors: Sanches Luiz Vitor Crepaldi , Ludwig Fernanda , Villas Bôas Roberto Lyra , Mateus Caroline De Moura D'Andréa
Published: January 2018

Bromeliads are plants that have a high variability in the fertilization possibilities. Bromeliads are plants that have a high variability in the fertilization possibilities. This is due to the capacity of absorption of water and nutrients by their foliar trichomes and root system. This research was conducted with the objective to evaluate the development of Aechmea fasciata plants according to the substrate base saturation and the application methods of the nutritive solution. The experiment was conducted in a greenhouse with light intensity between 8,000 and 9,000 Lx. The experimental design was a randomized block design with a factorial statistical arrangement 2x5 factorial (2 percentages of substrate base saturation x 5 combinations between the methods of fertirrigation) with 4 repetitions and 7 plants by portion. The substrate base saturation (V%) established was from 20% to 40% and the fertirrigation was provided by a leaf cistern and directly in the substrate, following these proportions: 100% leaf cistern, 75% leaf cistern and 25% substrate, 50% leaf cistern and 50% substrate, 25% leaf cistern and 75% substrate and 100% substrate. The plants were conducted in vase number 11, 15 and 17, and in each change of vases, it was evaluated the plant height, the rosette diameter, the stalk diameter, the number of leaves and the leaf width. The dry phytomass and leaf area were determined in the vase changes 15 and 17. Moreover, the root exploration and the inclination degree of the plants were determined in the end of the cultivation in vase 17. As conclusion, substrate base saturation greater than 20% damages the growth of Aechmea fasciata plants. The best development of the aerial and root part of Aechmea fasciata plants were achieved when 75% of the nutritive solution is applied via cistern and 25% via substrate.

Интегро-дифференциальные уравнения второй краевой задачи линейной теории упругости.
Сообщение 1. Однородное изотропное тело
Authors: Стружанов Валерий Владимирович , Struzhanov Valerii Vladimirovich
Published: January 2018

Система уравнений второй краевой задачи линейной теории упругости для однородного изотропного тела сведена к двум разным интегро-дифференциальным уравнениям фредгольмовского типа, что позволило для их исследования применить теоремы Фредгольма. Определены спектральные радиусы соответствующих операторов и доказано существование и единственность решения второй краевой задачи. Также установлено, что решение второго интегро-дифференциального уравнения можно найти методом последовательных приближений и представить его сходящимся со скоростью геометрической прогрессии рядом Неймана. Применение методики проиллюстрировано на примере расчета остаточных напряжений в закаленном цилиндре.

Authors: Garg Naveen , Dhruw Siddharth , Gandhi Laghu
Published: January 2018

The paper presents the application of Artificial Neural Networks (ANN) in predicting sound insulation through multi-layered sandwich gypsum partition panels. The objective of the work is to develop an Artificial Neural Network (ANN) model to estimate the Rw and STC value of sandwich gypsum constructions. The experimental results reported by National Research Council, Canada for Gypsum board walls (Halliwell et al., 1998) were utilized to develop the model. A multilayer feed-forward approach comprising of 13 input parameters was developed for predicting the Rw and STC value of sandwich gypsum constructions. The Levenberg-Marquardt optimization technique has been used to update the weights in back-propagation algorithm. The presented approach could be very useful for design and optimization of acoustic performance of new sandwich partition panels providing higher sound insulation. The developed ANN model shows a prediction error of ±3 dB or points with a confidence level higher than 95%.
DAB vs DAB+ Radio Broadcasting: a Subjective Comparative Study
Authors: Gilski Przemysław
Published: January 2018

In the age of digital media, delivering high quality content to consumers is one of the most demanding tasks. There exist numerous broadcasting standards, with different pros and cons, and the DAB/DAB+ (Digital Audio Broadcasting) system is one of the most popular among them. From an engineer’s perspective, efficient resource management under limited bandwidth conditions has always been a challenge. In this paper a subjective quality assessment study of the DAB and DAB+ broadcasting system is performed on a representative group of signal samples. It describes the radio link, including a fully functional transmitter designed for the purpose of this test, as well as the receiver side representing a commercially available consumer device, for a truly real-time and end-to-end quality evaluation.

Authors: Okoń-Fąfara Marta , Kawalec Adam , Fąfara Bartłomiej
Published: January 2018

The paper presents a project of a low-cost prototype version of a wideband air sonar and the problems occurring during its development process. The aim of this work was to design a short range air sonar capable of creating the reflectivity map of its surroundings using an arbitrary shape wideband signal. The transmitting and receiving transducers that have been chosen for this application typically work in pulsed operation modes. Therefore, dedicated output and input circuits had to be designed to expand its capabilities without information losses. The signal generation, transmission, reception and storage are managed by a Discovery evaluation board with a STM32 microcontroller. The receiving data are saved on a SD card and are processed off-line.
Socialist Postmodernism. The Case of the Late Soviet Lithuanian Architecture
Authors: Mankus Martynas
Published: January 2018

The aesthetical and cultural features of Lithuanian architecture related to Postmodernism are closely connected to socio-political, socioeconomic and sociocultural transformations at the end of the 20th century. The article presents an interpretation of modernisation-related processes, which affected and shaped the Lithuanian architecture of the late socialism. The expression of Postmodernism is analysed as an alternative to industrialization, typification and mass production. The aim of the article is to establish and analyse the social factors that have determined the appearance of postmodern architecture and its functioning in society, and to reveal ideological and aesthetical intersections of architecture, and the relationship between late socialism and Postmodernism.
Network Connections and Neighbourhood Perception: Using Social Media Postings to Capture Attitudes among Twitter Users in Estonia
Authors: Hess Daniel Baldwin , Iacobucci Evan , Väiko Annika
Published: January 2018

The residential landscape of a city is key to its economic, social, and cultural functioning. Following the collapse of communist rule in the countries of Central and Eastern Europe (CEE) in the late 1980s and early 1990s, urban residential dynamics and household mobility have been critical to urban change under new economies and political systems. This article explores neighbourhood perception, which is a link in the chain to better explanation of socio-spatial processes (and their interruption by the socialist system). We use a novel data set – opinions expressed on one of social media (Twitter), and a novel empirical method – neural network analysis, to explore people’s current attitudes and perceptions about the neighbourhoods and districts in Tartu, Estonia. The findings suggest that Twitter comments about urban neighbourhoods display attitudinal and perceptual commentary, which is subdued compared to other subjects. The socialist goal of homogeneity in neighbourhoods is not reflected in present day perspectives about urban neighbourhoods, 25 years after the disintegration of the USSR. Ambivalence about neighbourhoods persists, but this ambivalence may be in flux. Older, formerly neglected neighbourhoods, the subject of positive perception on social media, are currently experiencing increased investment, and the observed trends in our data support a narrative of neighbourhood transition.
Classifying Scaled-Turned-Shifted Objects with Optimal Pixel-to-Scale-Turn-Shift Standard Deviations Ratio in Training 2-Layer Perceptron on Scaled-Turned-Shifted 4800-Featured Objects under Normally Distributed Feature Distortion
Authors: Romanuke Vadim V.
Published: January 2018

The problem of classifying diversely distorted objects is considered. The classifier is a 2-layer perceptron capable of classifying greater amounts of objects in a unit of time. This is an advantage of the 2-layer perceptron over more complex neural networks like the neocognitron, the convolutional neural network, and the deep learning neural networks. Distortion types are scaling, turning, and shifting. The object model is a monochrome 60 × 80 image of the enlarged English alphabet capital letter. Consequently, there are 26 classes of 4800-featured objects. Training sets have a parameter, which is the ratio of the pixel-to-scale-turn-shift standard deviations, which allows controlling normally distributed feature distortion. An optimal ratio is found, at which the performance of the 2-layer perceptron is still unsatisfactory. Then, the best classifier is further trained with additional 438 passes of training sets by increasing the training smoothness tenfold. This aids in decreasing the ultimate classification error percentage from 35.23 % down to 12.92 %. However, the expected practicable distortions are smaller, so the percentage corresponding to them becomes just 1.64 %, which means that only one object out of 61 is misclassified. Such a solution scheme is directly applied to other classification problems, where the number of features is a thousand or a few thousands by a few tens of classes.
Novel PID Tracking Controller for 2DOF Robotic Manipulator System Based on Artificial Bee Colony Algorithm
Authors: Elkhateeb Nasr A. , Badr Ragia I.
Published: January 2018

This study presents a well-developed optimization methodology based on the dynamic inertia weight Artificial Bee Colony algorithm (ABC) to design an optimal PID controller for a robotic arm manipulator. The dynamical analysis of robotic arm manipulators investigates a coupling relation between the joint torques applied by the actuators and the position and acceleration of the robot arm. An optimal PID control law is obtained from the proposed (ABC) algorithm and applied to the robotic system. The designed controller optimizes the trajectory of the robot’s end effector for a time-variant input and makes the robot robust in the presence of external disturbance.
Hermite-Hadamard Type Fractional Integral Inequalities for Generalized (r; g; s; m; ϕ)-Preinvex Functions
Authors: Kashuri Artion , Liko Rozana
Published: January 2018

In the present paper, a new class of generalized (r; g; s; m; ϕ)-preinvex functions is introduced and some new integral inequalities for the left hand side of Gauss-Jacobi type quadrature formula involving generalized (r; g; s; m; ϕ)-preinvex functions are given. Moreover, some generalizations of Hermite-Hadamard type inequalities for generalized (r; g; s; m; ϕ)-preinvex functions via Riemann-Liouville fractional integrals are established. These results not only extend the results appeared in the literature (see [1],[2]), but also provide new estimates on these types.
Extension of Some Results on the (SSIE) and the (SSE) of the Form F ⊂ ℇ + F′ x and ℇ + Fx = F
Authors: Malafosse Bruno de
Published: January 2018

Given any sequence a = (an)n≥1 of positive real numbers and any set E of complex sequences, we write Ea for the set of all sequences y = (yn)n≥1 such that y/a = (yn/an)n≥1 ∈ E. In this paper we deal with the solvability of the (SSIE) of the form ℓ∞ ⊂ ℇ+F′x where ℇ is a linear space of sequences and F′ is either c0, or ℓ∞ and we solve the (SSIE) c0 ⊂ ℇ + sx for ℇ ⊂ (sα)∆ and α ∈ c0. Then we study the (SSIE) c ⊂ ℇ + s(c)x and the (SSE) ℇ + s(c)x = c. Then we apply the previous results to the solvability of the (SSE) of the form (ℓrp)∆ + Fx = F for p ≥ 1 and F is any of the sets c0, c, or ℓ∞ . These results extend some of those given in [8] and [9].

Authors: Kałużewicz Alina , Gąsecka Monika , Spiżewski Tomasz
Published: January 2018

Biostimulants are commonly used in horticulture, primarily to increase yield quantity and quality, as well as plant tolerance to stress. The purpose of the study was to determine the effect of amino acid-based biostimulants and amino acids in combination with Ascophyllum nodosum filtrate, applied during the growing season on the phenolic content in broccoli heads both after harvest and after long storage in a cold store. The seedlings were planted in mid-July, and heads were harvested from September to October in each year of the study. Ascophyllum nodosum filtrate at a concentration of 1% was used during seedling production. The plants were watered with biostimulants twice, in the fourth and fifth week after sowing. They were also sprayed with amino acid-based biostimulants (1.5 dm3 ha-1) three times, i.e. after the second, fourth and sixth week after planting. The biostimulants were not used in the control treatment. After harvest, the heads were stored for three weeks in a cold store at 1-2°C and 95% RH. Chemical analyses of total phenolic, caffeic, ferulic and sinapic acids, and of quercetin and kaempferol were carried out on samples of fresh broccoli and after the first, second and third week of storage. It was found that the application of biostimulants resulted in a significant increase in the total phenolic content, sinapic acid content, as well as quercetin content. Both in the control treatment and in the plants treated with the biostimulants, the concentration of all the tested phenolic compounds increased with the duration of storage.

Published: January 2018

As a sequel to the current advancement in ethology, this study was designed to provide information on the brain size of the African grasscutter at specific postnatal periods and to extrapolate these findings to the behaviour of the rodent in its natural habitat. Brain samples were extracted from African grasscutter neonates on postnatal day 6, juveniles on postnatal day 72 and adults on postnatal day 450 by basic neuro-anatomical techniques. The weight, volume and dimensions of the brain samples were determined in absolute and relative terms. Their encephalisation quotient was also computed. There was a very strong positive correlation between nose-rump length and brain length in the neonates. The relative brain weight of neonates, juveniles and adults were 3.84 ± 0.12 %, 2.49 ± 0.07 % and 0.44 ± 0.03 %, respectively. The differences were significant (P < 0.05). The encephalisation quotient of juveniles was 1.62 ± 0.03 while that of the adult was 0.49 ± 0.02. The difference was significant (P < 0.05). The results were extrapolated to the animal’s cognitive ability, and compared with other rodents. It was concluded that the juvenile African grasscutter may have higher cognitive ability than the adult rodent, thus, juveniles should be preferred in physiological studies of memory and cognition.
Changes in Temperature of the Equine Skin Surface Under Boots after Exercise
Authors: Solheim T. N , Tarabová L. , Faixová Z.
Published: January 2018

Equine distal limbs have evolved to have long tendons coupled with strong, tendinous muscles positioned proximally on the leg, thus enabling the horse to achieve highly efficient locomotion. The tradeoff is, that the tendons are left unprotected and prone to injuries, therefore they are often protected by various boots and bandages, which may insulate the limbs and cause hyperthermia in the underlying tendons. The actual mechanism for the degeneration of tendons is currently unknown, but damaging temperature increases due to hysteresis in hardworking horses has been suggested as a possible cause. This study compared the skin temperature of the palmar/ plantar metacarpal/metatarsal regions of the limbs after exercise with various types of boots and bandages - primarily tendon boots, leather boots and fleece bandages. Several horses were measured before and after the completion of a standard exercise test. The boots or bandages were removed immediately after the exercise and the temperature was measured at 3 separate places with A Testo 850i infrared thermometer. The differences in temperature increases between the various kinds of boots were compared. The results showed a significantly higher average temperature increase in horses wearing boots or bandages compared to the bare limb. The fleece bandages seemed to accumulate the highest amount of heat, followed by the tendon boots.
