Goal focused positive psychotherapy: an integration of positive psychology and psychotherapy

ABSTRACT This article introduces the empirical support for and theoretical tenets of Goal Focused Positive Psychotherapy (GFPP), a comprehensive, evidence-based, psychotherapy model. GFPP’s approach emerges from positive and social psychology research, and is informed by psychotherapy research from the common and contextual models. Its interventions focus on idiosyncratic and multiculturally-attuned client factors, particularly client strengths and goals, in an effort to increase subjective well-being and facilitate the client’s experience of a meaningful, satisfying life. Enhanced client well-being provides more robust and abundant resources for proactively addressing presenting concerns without requiring intensive focus on client deficits, symptoms, or trauma. The mechanism of change is positive emotion, as informed by the broaden-and-build [Fredrickson, B. L. (2001). The role of positive emotions in positive psychology: The broaden-and-build theory of positive emotions. American Psychologist, 56(3), 218–226. doi:10.1037/0003-066X.56. 3.218] biopsychosocial model. The therapeutic alliance creates a healing context cultivated through a focus on hope, strengths, and client-centred experiences of self-determination.
What Can Practitioners Learn from the Narratives of Young Refugees

Abstract Current dominant discourses around refugees in the UK focus on one of two viewpoints. The first positions refugees as “the other”, distinctly different from the general British population and subsequently less entitled to help, support and resources. The alternative discourse positions refugees as “helpless”, in need and deserving of support. A significant body of academic literature in this area focuses on past, traumatic and adverse experiences of refugees. In positioning refugees as vulnerable, it could be argued that the literature detracts from the individual aspirations of refugees and the barriers they may face to resettlement in the UK. This research aimed to explore the narratives of young refugees about their journey from their home countries into the UK, with a particular focus on post-migration factors. This research adopted a social constructionist perspective and used a narrative approach in its inquiry. In doing so, it aimed to prioritise voice and empower the narrators to embrace their subjective experience and interpretations of their journey and resettlement in the UK. The narrators included five young people aged fourteen to seventeen who came to the UK as refugees. Co-constructed narratives were facilitated during semi-structured interviews. Rich interpretations were sought from within as well as across narratives. Overlapping themes included: language as an integral part of helping resettlement, experience of racism as a hindering factor, and the role of family and other protective factors. Potential implications of the research are discussed alongside an exploration of their relevance for the profession of Educational Psychology. Key terms: Refugees, young people, transition, identity, narrative, Educational Psychology. Research supervisor: Dr Anthony Williams
A Robust Algorithm for OFDM Synchronization with Modified Polyphase Training Sequences

Orthogonal Frequency Division Multiplexing (OFDM) systems are sensitive to timing and frequency estimation errors, which causes inter-symbol-interference (ISI) and intercarrier-interference (ICI), leading to degradation in the system performance. An algorithm is presented in this paper, based on modified polyphase sequences; proposed for timing and frequency synchronization of OFDM system which is robust, efficient and computationally less complex. The proposed algorithm gives 100% success of timing index acquisition at 10 dB SNR which is at least 5 dB less compared to all existing algorithms. The algorithm is also compatible with IEEE 802.16e wireless Metropolitan Area Network (MAN) standard. This approach is based on modification of polyphase sequences by taking FFT of it.
A reliable route selection algorithm using Global Positioning Systems in mobile ad-hoc networks

The routing protocols designed for wired networks can hardly be used for mobile ad-hoc networks due to unpredictable topology changes, and thus several routing protocols for mobile ad-hoc networks have been proposed. The goal of this paper is to select the most reliable route that is impervious to failures by topological changes by mobile nodes' mobility. To select a reliable route, we introduce the concept of stable zone and caution zone, and then apply it to the route discovery procedure of the existing on-demand routing protocol (i.e. AODV). The concept of the stable zone and caution zone, which are located in a mobile node's transmission range, is based on a mobile node's location and mobility information received by Global Positioning System (GPS). The proposed protocol was evaluated by simulation in various conditions and we got an improved performance.
Seismicity at the southern East Pacific Rise from recordings of an ocean bottom seismometer array

[1] Seismic data recorded by ocean bottom seismometers (OBSs) at the southern East Pacific Rise (SEPR) were analyzed to characterize seismicity at fast spreading mid-ocean ridges. An automated event detection algorithm based on pattern recognition was developed to identify earthquake-generated T phases. The waveform cross-correlation and least squares method was found to provide more robust estimates of T phase relative travel times than the method of picking T phase maximum amplitude. The OBSs and subsequent equatorial Pacific hydrophones recorded earthquakes near an earthquake swarm in 1992, which was located � 300 km west of the ridge axis at about 18� S and 116� W. The process that generated the 1992 swarm either was reactivated 3 years later during the OBS experiment or has been continuously active in the past decade. This longterm activity suggests renewable stresses, which are consistent with the interpretation that magma injection was the cause of the 1992 swarm. In contrast to the swarm characteristics of earthquakes on the west flank of the ridge axis, earthquakes on the Nazca flank were randomly distributed in time and space. This difference in seismicity may result from the difference in the thermal structure of the Pacific and Nazca plates. The few earthquakes located at or near the ridge axis had very small magnitudes, reflecting the presence of shallow magma chambers and the thin elastic layer of the SEPR. This result suggests that acoustic monitoring of earthquakes associated with dike intrusion is difficult at regional scales at the SEPR. There is no apparent correlation between seismicity and off-axis seamounts.

Changing performance among Russian retail workers: Effectively transferring American management techniques

Recent political and social activities in Central and Eastern Europe have created an environment of "transformational change" (Jick, 1992). Jick describes such a magnitude of change as representing a complete abandonment of traditional behaviour, expectations and theories in favour of completely new alternatives or innovations. Such change may be a proactive decision for organizational renewal, or a reaction to recognized obsolescence. The concept of transformational change has also been recently popularized in practitioner work under the slogan of "Paradigm Shifts" (Barker, 1992). Paradigm shifts, in this context, are cited as a complete change in the rules, tools, and approaches to behaviour. Little stretching of the imagination is required to conclude that Central and Eastern European nations are currently experiencing paradigm shifts, or transformational change. Our focus in this article is on whether it is appropriate and effective to apply American management techniques to implement change in Russian enterprises. Current events in Russia provide an unprecedented opportunity for assessing the capability of existing theories of change and development to assist in revitalizing economic and management practices. While there is a closer cultural similarity to Western Europe (McNulty, 1992), Russia (as well as many other Central and Eastern European countries) has preferred to actively seek assistance from the United States. In response to these requests, American universities and federal agencies have created several programmes to facilitate the change process. Indeed, the desire of Central and Eastern Europeans to change, and the desire of Americans to help them change has led to many symbiotic relationships. We, the authors, have been fortunate enough to be involved in some of these efforts. However, before getting swept up in the current of good intentions, Americans might evaluate their ability to serve effectively as change agents in these ventures.

Eating disorders in adolescence: attachment issues from a developmental perspective

In the present article we review findings from an emerging body of research on attachment issues in adolescents with eating disorders from a developmental perspective. Articles for inclusion in this review were identified from PsychINFO (1966–2013), Sciencedirect (1970–2013), Psychindex (1980–2013), and Pubmed (1980–2013). First, we will outline the crucial developmental changes in the attachment system and discuss how they might be related to the early onset of the disease. Then we will report on the major results from attachment studies using self-report and narrative instruments in that age group. Studies with a developmental approach on attachment will be analyzed in more detail. The high incidence of the unresolved attachment pattern in eating disorder samples is striking, especially for patients with anorexia nervosa. Interestingly, this predominance of the unresolved category was also found in their mothers. To date, these transgenerational aspects are still poorly understood and therefore represent an exciting research frontier. Future studies that include larger adolescent samples and provide a more detailed description including symptom severity and comorbidity would contribute to a better understanding of this complex and painful condition.
The intracellular region of Notch ligands Dll1 and Dll3 regulates their trafficking and signaling activity

Genetic studies have shown that ubiquitination and endocytosis of the Drosophila ligand Delta in signal-sending cells are required for activation of Notch signaling, but how these events promote Notch activation remains poorly understood. Here, we show that an ubiquitination-defective mutant of the murine Delta-homologue Dll1 is endocytosed but, in contrast to the wild-type Dll1, is unable to subsequently recycle back to the cell surface or to bind Notch1 efficiently. These results demonstrate that ubiquitination, although not required for endocytosis, is essential for Dll1 recycling and that recycling is required to acquire affinity for the receptor. On the other hand, a chimeric molecule encompassing the extracellular domain of Dll1 and the transmembrane/intracellular domain of Dll3, which contains no lysine, is endocytosed, recycled, and interacts with Notch1 but is unable to induce transendocytosis of the extracellular region of Notch1 or to signal. These observations suggest that the chimera uses an ubiquitination-independent signal to recycle, allowing it to acquire affinity for Notch1. Our results support the idea that ligand recycling determines its competence to bind efficiently to the receptor but that this is insufficient to allow it to perform transendocytosis, an event required for activation of Notch signaling. Finally, the present study indicates that Dll1 partially localizes to lipid microdomains, whereas both ubiquitination-defective Dll1 and the Dll1–3 chimera are excluded from these compartments, suggesting that these microdomains provide the environment necessary for Dll1 to activate Notch signaling.
A testbed for the evaluation of MPEG video transmission on ATM networks

Most of the new broadcasting and multimedia applications intensively rely on networked video. The current trend for distributing digital video on broadband ISDN networks is towards the adaptation of MPEG streams on ATM networks. End-to-end testing of such communication systems is very important and requires robust testing methodologies that are capable of evaluating both coding and transmission errors. This paper proposes a complete architecture for doing so. The system is entirely automatic, relies on synthetic test patterns and estimates the subjective quality of video coding and network transmission.
Effects of standard model Kaluza-Klein excitations on electroweak observables

The presence of an extra dimension of size $R\ensuremath{\approx}{\mathrm{TeV}}^{\ensuremath{-}1}$ introduces a tower of Kaluza-Klein gauge boson excitations that affects the standard model relations between electroweak observables. The mixing of the W and Z bosons with their excitations changes their masses and couplings to fermions. This effect depends on the Higgs field, which may live in the bulk of the extra dimension, on its boundary, or may be a combination of both types of fields. We use high-precision electroweak data to constrain $1/R$. We find limits from 1 to 3 TeV from different observables, with a model-independent lower bound of 2.5 TeV.
Contact spectroscopy for determination of stratigraphy of snow optical grain size

Abstract We present a technique for in situ measurement of the vertical and spatial stratigraphic distribution of snow optical grain size with a coupled contact illumination probe and field spectroradiometer. Accurate measurements of optical-equivalent grain size are critical for modeling radiative properties of snow such as spectral albedo and microwave emission. Measurements of the spectral reflectance of the snow-pit surface are made at 2 cm intervals in the vertical plane under constant illumination and view geometries. We invert the integral of the continuum normalization of the ice absorption feature with maximum at 1.03 μm wavelength for optical-equivalent grain size using the validated model of Nolin and Dozier (2000) that has accuracy of ±10–50 μm across the grain-size range 50–900 μm. Results are presented for an alpine site in southwest Colorado, USA, across the ablation season and for a Greenland ice-sheet site at the onset of snowmelt. These results suggest that traditional measurements of grain size using a hand lens are nearly accurate only for rounded grains (R2 = 0.41, rmse = 160 μm); for polycrystals and faceted grains the hand-lens approach is very inaccurate (R2 = 0.03 and 0.24, rmse = 1206 and 1010 μm, respectively). We demonstrate an order-of- magnitude improvement in modeling of shortwave spectral albedo and net shortwave flux with contact spectroscopy measurements of grain-size stratigraphy over those from a hand lens.
Auxiliary matrices for the six-vertex model and the algebraic Bethe ansatz

We connect two alternative concepts of solving integrable models, Baxter's method of auxiliary matrices (or Q-operators) and the algebraic Bethe ansatz. The main steps of the calculation are performed in a general setting and a formula for the Bethe eigenvalues of the Q-operator is derived. A proof is given for states which contain up to three Bethe roots. Further evidence is provided by relating the findings to the six-vertex fusion hierarchy. For the XXZ spin-chain we analyse the cases when the deformation parameter of the underlying quantum group is evaluated both at and away from a root of unity.
A Note on Boltzmann Tournament Selection for Genetic Algorithms and Population-Oriented Simulated Annealing

This note describes a selection procedure for genetic algorithms called Boltzmann tournament selection. As simulated annealing evolves a Boltzmann distribution in time using the Metropolis algorithm or a logistic acceptance mechanism, Boltzmann tournament selection evolves a Boltzmann distribution across a population and time using pairwise probabilistic acceptance and anti-acceptance mechanisms. In this note, the motivation , the theory of operation, some proof-of-principle computational experiments, and a Pascal implementation of the algorithm are presented. The efficient use of Boltzmann tournament selection on parallel hardware and its connection to other niching mechanisms are also considered.
PENGARUH TINDAKAN KEPERAWATAN REDUKSI LUKA TEKAN TERHADAP PENURUNAN RISIKO LUKA TEKAN

Decubitus is a very serious problem especially for patients who hospitalized for long time with limited activity. Decubitus can increase the duration of hospital stay so that will increase the burden, especially the cost of hospitalization along with length of stay in hospital. This research of purpose to know the influences of nursing intervention to reduce pressure sore to reducing risk of pressure sore at RSU PKU Muhammadiyah Purworejo. This research design used “Pre and post test without control group " with intervention reduction of risk pressure ulcer. This research is conducted in July 2016 with consecutive sampling method of 40 patients. Observations of pressure sore level on bed rest patiens done before and after treatment. The evaluation was done with wilcoxon ranks test and continued with cross tabulation for each treatment. The results showed a significant increase in risk of injury scores by 31 respondents, p = 0,000 <0.05. While the result of cross tabulation showed decreased risk of injured press on each level consisting of: high risk from 18 respondents down to 12 (66,7%) with baring and mass action. For the medium category there are 18 respondents 18 respondents dropped to 13 (72.1%) into low risk. As for the very high risk of 2 respondents who experienced a decrease in risk as much as 1 respondent while 1 other respondent remained, action at very high risk of wound care done according to grade I wound press. Likewise for low risk categories did not change, this is due to limited number of samples taken. The conclusion of this study is a decrease of risk pressure sore after applied preventive action for reduction of pressure sore in bed rest patients. The action apllied wound dressing, combination of massage and reposition, also health promotion.
Decision-Making Under Risk in Children, Adolescents, and Young Adults

Adolescents often make risky and impulsive decisions. Such behavior has led to the common assumption that a dysfunction in risk-related decision-making peaks during this age. Differences in how risk has been defined across studies, however, make it difficult to draw conclusions about developmental changes in risky decision-making. Here, we developed a non-symbolic economic decision-making task that can be used across a wide age span and that uses coefficient of variation (CV) in reward as an index of risk. We found that young children showed the strongest preference for risky compared to sure bet options of equal expected value, adolescents were intermediate in their risk preference, and young adults showed the strongest risk aversion. Furthermore, children's preference for the risky option increased for larger CVs, while adolescents and young adults showed the opposite pattern, favoring the sure bet more often as CV increased. Finally, when faced with two gambles in a risk–return tradeoff, all three age groups exhibited a greater preference for the option with the lower risk and return as the disparity in risk between the two options increased. These findings demonstrate clear age-related differences in economic risk preferences that vary with choice set and risk. Importantly, adolescence appears to represent an intermediate decision-making phenotype along the transition from childhood to adulthood, rather than an age of heightened preference for economic risk.
Engineered optical nonlocality in nanostructured metamaterials

We analyze dispersion properties of layered metal-dielectric structures, which can be considered as a simple example of nanostructured metamaterials. We demonstrate that, in sharp contrast to the results of the theory of effective media, the layered structure demonstrates strong optical nonlocality due to excitation of surface plasmon polaritons. Such nonlocality can be engineered by changing a ratio between the thicknesses of metal and dielectric layers. Importantly, the nonlocality leads to the existence of an additional extraordinary wave that manifests itself in the splitting of the transverse-magnetic polarized beam refracted at an air-metamaterial interface.
Cross Sectional Characterization of Factors Associated with Pediatric HIV Status Disclosure in Southern Ethiopia

Background Disclosure of HIV positive status to children and adolescents is a complex process. However, disclosure has been found to be associated with improved outcomes. The objective of the current study was to identify the predictors that facilitate disclosure of HIV status to children and adolescents and to study the reasons for non-disclosure. Methods Interviews of caregivers and reviews of records were done to collect data on caregiver and child information and details regarding the disclosure status of children. Bivariate analysis was done to test the association between HIV status disclosure and different caregiver and child factors. To identify the independent predictors of disclosure, we did multivariable logistic regression. Results A total of 177 children attending an HIV clinic were included. The mean age of the participants was 10.1 years (SD = 2.8), and about half (50.8%) were female. Most caregivers, 137 (77.8%) stated that disclosure of HIV status to children is important and should be done. However, disclosure had only been made to 59 (33.3%) of the participants. Child age more than 10 years [AOR = 6.7; 95%CI: 1.73–26.01], duration of HIV diagnosis of 5 years or more [AOR = 4.4; 95%CI: 1.26–15.06] and taking a zidovudin (AZT) based regimen [AOR = 3.5; 95%CI: 1.31–9.53] predicted HIV positive status disclosure. Additionally, length of treatment of caregivers of more than 14 years [AOR = 3.9; 95%CI: 1.07–14.61], disclosure of caregiver’s HIV status to children and/or others [AOR = 4.7; 95%CI: 1.19–18.74], and the child’s inquiry about their condition [AOR = 4.5; 95%CI: 1.16–17.43] increased the odds of disclosure. Conclusion The rate of disclosure among HIV infected children in southern Ethiopia is low. Primarily time-based factors were associated with the probability of HIV positive status disclosure and a specific regimen which has not been found previously. Further qualitative research may elucidate more on these factors; educational strategies may address some of these determinants.
