Shared Decision-Making—Balancing Between Power and Responsibility as Mental Health-Care Professionals in a Therapeutic Milieu
Authors: Beyene Lise S. , Severinsson Elisabeth , Hansen Britt S. , Rørtveit Kristine 
Published: January 2018

Background Shared decision-making (SDM) is supposed to position patient and expert knowledge more equal, in which will have an impact on how mental health-care professionals relate to their patients. As SDM has not yet been widely adopted in therapeutic milieus, a deeper understanding of its use and more knowledge of interventions to foster its implementation in clinical practice are required. Aim To explore how mental health-care professionals describe SDM in a therapeutic milieu as expressed through clinical supervision. The research question was “What are prerequisites for mental health-care professionals to practice SDM in a therapeutic milieu?” Methods A qualitative content analysis of data from focus groups dialogues in 10 clinical supervision sessions where eight mental health-care professionals participated was performed. Findings The theme, practicing SDM when balancing between power and responsibility to form safe care, was based on three categories: internalizing the mental health-care professionals’ attributes, facilitating patient participation, and creating a culture of trust. Conclusion SDM is a complex and arduous process requiring appropriate interventions. Clinical supervision is necessary for reflection on SDM and for improving practice in a therapeutic milieu.

Published: January 2018

Aims and methodTwo police liaison and section 136 schemes were developed alongside police services at different sites within the same NHS trust. In one, a mental health nurse worked with frontline police attending incidents related to mental health. The other involved nurses providing advice from the police control room. Section 136 detentions were measured over two 6-month periods (6 months apart) before and after practice change. Data analysed included total numbers of section 136 assessments, outcomes following subsequent assessment, and relevant diagnostic and demographic factors. Association of any change in section 136 total numbers and proportion subsequently admitted was investigated in both sites.ResultsThe model involving a nurse alongside frontline police showed significant reduction in section 136 numbers (38%, P <0.01) as well as greater admission rates (P = 0.01). The scheme involving support within the police control room did not show any change in section 136 detention but showed a non-significant (P = 0.16) decrease in subsequent admission.Clinical implicationsMental health nurses working alongside frontline police officers can help improve section 136 numbers and outcomes.
Contribution to Casein Determination by UV Spectrophotometry

Published: January 2018

Abstract
In the present paper, the interaction between copper ions and proteins is presented, in order to elaborate a simple and rapid spectrophotometric assay of casein in milk. Under alkaline conditions, copper ions form the biuret complex with the proteins, which can be used in protein determination. Although very specific, the biuret method is less sensitive. Using insoluble copper phosphate, casein is able to extract copper ions, with which it forms the biuret complex, while either the complex or copper ions could be determined in the ultraviolet range. Indeed, an increased absorbance of biuret complex at 215 nm was found. Nevertheless, copper ions can be determined in UV as well, their concentration being proportional to that of casein. When used tetraglycine instead casein, mass spectrometric measurements at pH higher than 11 revealed the formation of complexes with many copper ions bound to each peptide bond-containing molecule. Nevertheless, on diluting the biuret solution the complex may dissociate leading to very complex UV spectra that should be further studied.
Valuation of large variable annuity portfolios: Monte Carlo simulation and synthetic datasets
Authors: Gan Guojun , Valdez Emiliano A. 
Published: January 2018

Abstract
Metamodeling techniques have recently been proposed to address the computational issues related to the valuation of large portfolios of variable annuity contracts. However, it is extremely diffcult, if not impossible, for researchers to obtain real datasets frominsurance companies in order to test their metamodeling techniques on such real datasets and publish the results in academic journals. To facilitate the development and dissemination of research related to the effcient valuation of large variable annuity portfolios, this paper creates a large synthetic portfolio of variable annuity contracts based on the properties of real portfolios of variable annuities and implements a simple Monte Carlo simulation engine for valuing the synthetic portfolio. In addition, this paper presents fair market values and Greeks for the synthetic portfolio of variable annuity contracts that are important quantities for managing the financial risks associated with variable annuities. The resulting datasets can be used by researchers to test and compare the performance of various metamodeling techniques.
The influence of relationship beliefs on gift giving
Authors: Rai Dipankar , Lin Chien-Wei , Hong JungHwa , Kulick George 
Published: January 2018

Abstract
People have fundamental beliefs about what constitutes a good relationship, known as implicit theories of relationship, where some people have destiny beliefs whereas others have growth beliefs. People with destiny beliefs believe that potential partners are meant either for each other or not, whereas people with growth beliefs believe that successful relationships are cultivated and developed. This research shows that different implicit theories of relationship influence consumers’ gift choice to their significant others. We demonstrate, through two studies, that consumers with destiny beliefs prefer giving gifts that are more feasible in nature, whereas consumers with growth beliefs prefer giving gifts that are more desirable in nature. We show that this effect is mediated by desirability-feasibility considerations. Specifically, consumers with destiny beliefs focus on feasibility considerations, which leads them to choose a highly feasible gift. Conversely, consumers with growth beliefs focus on desirability considerations, which leads them to choose a highly desirable gift. We also discuss the theoretical and managerial implications of our research.
Guard Sets in Tor using AS Relationships
Authors: Imani Mohsen , Barton Armon , Wright Matthew 
Published: January 2018

Abstract
The mechanism for picking guards in Tor suffers from security problems like guard fingerprinting and from performance issues. To address these issues, Hayes and Danezis proposed the use of guard sets, in which the Tor system groups all guards into sets, and each client picks one of these sets and uses its guards. Unfortunately, guard sets frequently need nodes added or they are broken up due to fluctuations in network bandwidth. In this paper, we first show that these breakups create opportunities for malicious guards to join many guard sets by merely tuning the bandwidth they make available to Tor, and this greatly increases the number of clients exposed to malicious guards. To address this problem, we propose a new method for forming guard sets based on Internet location. We construct a hierarchy that keeps clients and guards together more reliably and prevents guards from easily joining arbitrary guard sets. This approach also has the advantage of confining an attacker with access to limited locations on the Internet to a small number of guard sets. We simulate this guard set design using historical Tor data in the presence of both relay-level adversaries and networklevel adversaries, and we find that our approach is good at confining the adversary into few guard sets, thus limiting the impact of attacks.
Problem-Based Learning and Teaching in Construction-Oriented Secondary Vocational Education

Published: January 2018

Abstract
It is a commonplace view today that schools do not prepare students properly for solving technical problems emerging in an ever-changing world. As attested by various PISA surveys, Hungarian students can only retrieve their knowledge situations. Their self-regulated learning, problem solving and cooperative skills do not develop in accord with the requirements of their future career. Positive transfer effects are only slightly expressed in learning, especially in the long run.
Internet Addiction in Adolescents

Abstract
The possibilities offered by the use of the Internet increasingly intensify the problem of Internet addiction, which has become more prevalent in the last decade, marked by the growing availability of mobile devices and new media and their exacerbation of the problem. Research on Internet addiction, initiated by Kimberly Young at the end of the twentieth century, usually appears in the literature in the context of young people who have been found to be most vulnerable. The phenomenon is known as Adolescent Internet Addiction. Compulsive use of the Internet is a complex phenomenon, its effects being visible in almost all aspects of a young person’s social life. It is manifested in a variety of pathological behaviors and emotional states grouped into several major psycho-physical and social effects that may appear simultaneously, e.g. anger, depression, loneliness or anxiety associated with the lack of access to the network, the weakening of social ties, withdrawal from real life, lack of educational achievement, chronic fatigue or deteriorating health. The authors of this study aim to assess the level of Internet addiction among adolescents in Poland and indicate its main behavioral manifestations, in the students surveyed, which influence their pathological use of the Internet. Our study involved a total of 505 students from three high schools located in Rzeszow (N = 505) and was carried out by questionnaires, including, among others, The Problematic Use of the Internet (PUI) which is the Polish adaptation of Kimberly Young’s Internet Addiction Test (IAT) (Cronbach’s α = 0.89). Statistical analysis of responses from the PUI test allowed us to determine (1) the level of Internet addiction among these adolescents, whereas the univariate (ANOVA) analysis enabled us (2) to verify the hypothesis of the existence of differences in the level of Internet addiction among the investigated groups as far as gender, place of residence or grade are concerned. Generally, the results obtained in our research indicate that the level of Internet addiction among the adolescents investigated is not very high, although two thirds of our respondents showed an above average level of addiction, and every ninth respondent (approximately 11%) was highly addicted to the Internet, men being more often addicted (15.6%) than women (8.3%).
Different Aspects of Involving Family in School Life
Authors: Blândul Valentin-Cosmin 
Published: January 2018

Abstract
The school has come to not have a huge credibility even, sometimes being abandoned, primarily because, nowadays, no matter hierarchy and is not perceived as a value. The actual society no longer has trust in the educational establishment, the values acquired and ranked by the amount of learning embedded in it. Such an attitude is reflected by the relationship between “parent - teacher” and “student - teacher”. Based on these findings, the present study aims to investigate the main features of the relationship that is established between school and family, concerned how parents can get involved in school life effectively. The lot of subjects was represented by 212 teachers from secondary schools in Bihor, Romania and the instrument used in the research was a questionnaire consisting of 46 objective and subjective items. The results are very interesting and shows that many respondents argue that parents show indifference to the formal education of their children, not involved in the didactic or extracurricular activities and in school life, not take part in parent meetings or when called for, is difficult to communicate with parents etc. There are some cases when, because of the family economic situation is poor, parents send their children to work, offering less time and interest in their education and instruction.
Cracking novel shared targets between epilepsy and Alzheimer’s disease: need of the hour
Authors: Garg Nitika , Joshi Rupa , Medhi Bikash 
Published: January 2018

Abstract
Epilepsy and Alzheimer’s disease (AD) are interconnected. It is well known that seizures are linked with cognitive impairment, and there are various shared etiologies between epilepsy and AD. The connection between hyperexcitability of neurons and cognitive dysfunction in the progression of AD or epileptogenesis plays a vital role for improving selection of treatment for both diseases. Traditionally, seizures occur less frequently and in later stages of age in patients with AD which in turn implies that neurodegeneration causes seizures. The role of seizures in early stages of pathogenesis of AD is still an issue to be resolved. So, it is well timed to analyze the common pathways involved in pathophysiology of AD and epilepsy. The present review focuses on similar potential underlying mechanisms which may be related to the causes of seizures in epilepsy and cognitive impairment in AD. The proposed review will focus on many possible newer targets like abnormal expression of various enzymes like GSK-3β, PP2A, PKC, tau hyperphosphorylation, MMPs, caspases, neuroinflammation and oxidative stress associated with number of neurodegenerative diseases linked with epilepsy. The brief about the prospective line of treatment of both diseases will also be discussed in the present review.
Investigation of three-body wear of dental materials under different chewing cycles
Authors: Yılmaz Efe Cetin , Sadeler Recep 
Published: January 2018

Abstract
This paper investigates the three-body wear resistance rates of five restorative dental composite materials at different mastication cycles and compares the results with that of an amalgam material. Five specimens of each material were exposed three-body wear tests using a computer-controlled chewing simulator with steatite balls as the antagonist (1.6 Hz, 49 N load; 120,000, 240,000 and 480,000 mechanical cycles; and thermal cycling between 5 and 55°C at 5 min/cycle and 3000 cycles) immersed in a poppy seed slurry (three-body wear environment). Initially, the microhardness values of the composite materials in the Vicker’s hardness (HV) scale were determined. The mean volume loss of the worn surfaces was measured with a three-dimensional profilometer. Means and standard deviations were calculated, and statistical analysis was performed using one-way ANOVA (α=0.05). Additionally, scanning electron microscopy analysis was performed to examine the wear tracks on the surface. The interactions between the composite resin and mean volume loss were found to be significant. The three-body wear rates for the composites Durafil and Kalore composite were significantly higher than those of the other composites and the amalgam irrespective of the number of mastication cycles. Filtek Z250 and Filtek Supreme composite resins had good three-body wear resistance similar to that of the amalgam. However, this study suggests that the correlation between Vicker’s hardness and three-body wear resistance is not significant.

Experimental Study on Geomechanical Dilation of Oil Sands During Cold–Water Injection
Authors: Wang Xinkui , Chalaturnyk Rick , Huang Haibo , Leung Juliana 
Published: January 2018

Summary
Steam-assisted-gravity-drainage (SAGD) processes become effective only after thermal and hydraulic communication between an injection and production well has been established during the startup operation of the well pair. Conventional steam-circulation startup operations typically take 2 to 3 months to achieve interwell communication, but reductions in the startup time can have a favorable impact on project economics. Enhancement of interwell permeability using fluid-injection (water, or steam, or solvent) strategies to promote geomechanical dilation of the oil sands has been proposed as a startup technique. These fluid-injection processes will produce complex interactions of thermal, geomechanical, and multiple-phase flow behavior in the interwell formation region. Understanding better the role that these interactions play in establishing well-pair communication will provide opportunities to improve SAGD recovery performance.
A triaxial experimental program has been designed and executed to explore whether cold-water injection would be sufficient to induce enhancements in effective permeability to water from geomechanical dilation mechanisms. Sample preparation techniques were modified to allow the preparation of reconstituted, very dense water-wet/bitumen sand specimens with different fluid saturations and almost identical porosities. Reclaimed/cleaned tailings sand from oil-sands mining operations was used to prepare artificial specimens, which are representative of McMurray Formation oil sands. A water-wet or bitumen sand core plug was then tested in an environmental chamber to simulate reservoir boundary conditions in terms of stress state, temperature, and pore pressure. A set of experiments was carried out in a triaxial cell under either initial isotropic or initial anisotropic stress state. Experimental results highlight the promising potential to dramatically enhance effective permeability to water and porosity in the dilated zone using cold-water injection at modest levels of stress anisotropy. The experimental results also provide support for the development of numerical models used in predicting SAGD startup performance and proactive utilization of the dilation as startup process for in-situ oil-sands development.
Of Kings and Officers — The Judicial Development of Public Law
Authors: Selway Bradley 
Published: January 2018

The relationship of the King to the persons who actually perform the work of government has changed profoundly over the last 250 years. The purpose of this article is to analyse those changes and to analyse how the common law reacted (or failed to react) to them.For this purpose I propose first to consider the structure of English government in about 1750. Although the structure was already evolving into a more modern form, in 1750 it was still a relatively simple governmental structure based upon a sovereign Monarch and upon public officers, many of them in regional areas.At that time the common law clearly distinguished between the Monarch and his officers. Although the extent and importance of the various legal powers and immunities of the Monarch are now often overstated, the Monarch did possess special powers and immunities which reflected or, at least, were derived from his sovereignty.
Section 92 and the Regulation of E-Commerce: A Casenote on Betfair Pty Ltd V Western Australia
Authors: Ball Eli 
Published: January 2018

The internet is a new and ubiquitous tool for conducting business. In the age of e-commerce, distance and physical borders mean very little. The Constitution, however, was drafted at a time when trade and commerce was characterised by important geographical considerations, the most significant being the geo-political boundaries between the several colonies that became the States. The internet has all but destroyed whatever remnants of that age might have survived the previous 100 years. This tension between recent technological advancement and long established constitutional jurisprudence confronted the High Court in Betfair Pty Ltd v Western Australia.Betfair is one of a long line of cases dealing with the freedom of interstate trade and commerce enshrined in s 92 of the Constitution, the most litigated section of Australia's highest document of government. But it is also truly unique: Betfair is the first time that the freedom of interstate trade and commerce has been considered in an e-commerce context. Presented with this opportunity, the High Court has elaborated upon the approach to s 92 set down nearly 20 years ago in Cole v Whitfield. The outcome has significant consequences for both State and Commonwealth internet regulators.
The Definition and Discovery of Facts in Native Title: The Historian’s Contribution
Authors: Carter Anne 
Published: January 2018

The relationship between law and history has long been the subject of academic interest. Both disciplines have occasion to turn to the past, yet their purposes and methods for doing so often vary. Some commentators have noted the similarities between the two disciplines, describing them as ‘intellectual cousins’ who share a ‘natural affinity'. Yet, equally, commentators have noted the tensions between the two disciplines, depicting them not as allies but as strangers or enemies. These scholars have painted a picture of competing logics, suggesting that the clash between the law's ‘logic of authority’ and the historian's ‘logic of evidence’ creates an uneasy relationship.Although capturing the attention of both judges and commentators, the intersection between law and history continues to elude precise definition.
