From Proving Perfection to Seeking Support: The Lived Experiences of Adoptive Parents in Alberta

The purpose of this phenomenological study on the lived experiences of 14 adoptive parents in Alberta is to gain deeper insights into how parents (a) experience the process of adoption, and (b) seek support and receive support services. The intent is also to increase understanding and determine if any changes to current practices are needed. This study uncovers how some adoptive parents experience the process as traumatic, while others feel unsupported. The need to substantiate oneself as a perfect parent to get approved for adoption, and then request support for adoption after placement, can be both isolating and challenging for parents. Recommendations on adoption processes are discussed, as well as implications for the field of counselling.

Thinking (and Thinking…) About Perfection: A Test of the Perfectionism Cognitions Theory

The current body of work examined the link between perfectionism cognitions and depressive symptoms and, importantly, tested a central mechanism by which rumination acts as an intervening pathway in this relationship. These relationships form the underlying framework of the Perfectionism Cognitions Theory (Flett et al., 2016), which, to date, had not been empirically tested. The current body of work consisted of two separate studies. Study 1 used a community sample of adults (N = 175, 53.3% men, Mage = 28.3 years old). Results of structural equation modeling in Study 1 offered support for the Perfectionism Cognitions Theory. It was found that rumination represented an indirect pathway explaining the relationship between perfectionism cognitions and depressive symptoms. Study 2 used a sample of emerging adult students (N = 53, 84.9% women, Mage = 19.9 years old) to test the Perfectionism Cognitions Theory. Study 2 also closely examined the link between perfectionism cognitions and cognitive flexibility, a behavioural index of rumination that was measured by performance on a set-shifting task. Results of a test of indirect effects in Study 2 replicated the findings of Study 1 by supporting the Perfectionism Cognitions Theory and showing evidence that rumination represents a mechanism by which perfectionism cognitions are related to poorer well-being. Results of regression analysis did not show a link between perfectionism cognitions and set-shifting, but perfectionism cognitions were related to self-reported cognitive flexibility. Together, the findings support Flett et al.’s (2016) Perfectionism Cognition Theory and have important implications for research and practice.
Laser-Induced Fault Injection on Smartphone Bypassing the Secure Boot-Extended Version

This paper describes the outcome of a laser attack study on an Android smartphone targeting specifically the secure boot sequence. Laser fault injection has become a classical attack path in the secure chip industry to investigate potential security mitigation. The implementation of such attacks on a recent mobile phone remains relatively unexplored and represents different challenges, both at hardware and software levels. In this paper, we show how the device is crafted to get a direct access to the silicon and explain the corresponding experimental setup. By inserting our own software into the boot sequence, it was possible to achieve a fine characterization of the die sensitivity to laser emissions. With the knowledge of potential perturbations, several attack scenarios were built, allowing to malevolently get the highest level of privilege within the mobile phone.
Can cultural festivals function as counterspaces for migrants and refugees? The case of the New Beginnings Festival in Sydney

ABSTRACT Despite the recognised benefits of cultural festivals, it is still unclear how they may assist marginalised groups in mitigating the adverse effects of marginalisation. Informed by the Counterspace Framework, this paper seeks to address the gap at the nexus of leisure, events and marginalisation by considering the case of the New Beginnings Festival in Sydney. Using hybrid thematic analysis and based on data collected through participant observation, semi-structured interviews, and document analysis, we argue that the festival operates as a counterspace for attendees through the processes of narrative identity work, acts of resistance, and direct relational transactions. First, the festival validated experiences of rejection and marginalisation by attendees, and at the same time celebrated migrants and refugees by showcasing their capabilities/achievements. This lead to attendees’ sense of affirmation and acceptance. Second, the freedom to express themselves in culturally meaningful ways helped bolster the attendees’ self-concept. Third, social and institutional support, and leadership roles such as mentoring and volunteering were made possible at the festival, which enhanced attendees’ social capital in empowering ways. In addition, we highlight the importance of location for events as counterspaces. Our findings contribute to both the critical event studies and the counterspace literature.
Power and coordination in the multinational company : a post-heterarchical perspective

Multinational Companies (MNCs) are not only among the most important institutions in our globalising world, but are fascinating organisations given their complexity and the daily challenge they face of operating across different countries and cultures. However, MNC’s have mainly been theorised as a structure of units, with relatively little focus upon how they operate at the level of the individual (Piekkari & Welch, 2010). This thesis seeks to understand how individuals navigate the structures of the MNC and, using concepts of power, examines how different perspectives and interests are reconciled to enable coordination. In particular, this thesis explores the dynamics of individuals’ power relations in GlobeCo, a major European MNC that has evolved from a polycentric to an interdependent, heterarchical organisation (Hedlund, 1986). The analysis highlights the heterarchy as a context of ambiguity and contestation, reflected in continuous organisational fluidity, in which the formal units of the MNC are neither stable nor well defined. This suggests that GlobeCo needs to be considered as a post-heterarchical MNC in which interdependence, cultural and institutional pressures, and diverse interests are experienced, and resolved, at the individual level. The implications of the post-heterarchical form for our understanding of the MNC are considered.The thesis further shows how individuals rely upon the temporary acceptance of multiple forms of episodic power-in-use. Through examining a particular change initiative in depth, the thesis shows both how individuals leverage the different forms of power-in-use, but also use apparently everyday practices to build shared understanding, legitimacy and commitment – and through this achieve sufficient compatibility of understanding and actions, a transient intersubjective alignment, to allow coordination.As such, the thesis not only provides a better understanding of the heterarchical multinational, but highlights the role of the individual in shaping power relations to achieve coordinated action. In doing so, it gives insight into how individuals’ episodic action can shape systemic power relations that, in turn, provide the basis for episodic power-in-use.
Social and Emotional Learning in Practice: A Resource Review

Youth programs are an important context for social and emotional learning (SEL). To maximize opportunities for the development of skills such as self-management, empathy, and goal setting, youth workers need resources to increase practices that support SEL. Social and Emotional Learning in Practice: A Toolkit of Practical Strategies and Resources, Second Edition is a compilation of tools, templates, and activities that youth development programs can use to (a) enhance staff knowledge of SEL, how their program supports SEL, and their own emotional intelligence; (b) establish expectations, give feedback, and integrate reflection; (c) integrate SEL into program activities; and (d) collect SEL data for improvement. The 149-page toolkit is grounded in the Ways of Being model and is also informed by youth workers and youth from a variety of organizations. This is a turnkey resource that will be useful to youth development workers with a range of goals from overhauling their approach to SEL to identifying one activity for a single day of programming. The 2nd edition includes new icebreaker activities, an SEL Superpowers Board Game, creative data collection strategies, a reading list, and more.
Scalability of Cancer SurvivorLink TM : A Cluster Randomized Trial among Pediatric Cancer Clinics

Background: Children diagnosed with cancer are living longer and the survivor population is growing. However, most survivors develop late effects of radiation and chemotherapy shortly to years after completion of therapy, and the receipt of follow-up visits that are recommended by the Children’s Oncology Group (COG) is suboptimal nationally. Aims: The aims of this study are to: 1) evaluate the impact of a patient-controlled electronic personal health record (ePHR) and system (SurvivorLink) on care visit attendance, risk-based surveillance, and other secondary outcomes (i.e., patient activation, quality of life (QOL)); 2) measure the use, acceptability, and perceived usefulness of, and satisfaction with SurvivorLink; and 3) assess facilitators and barriers to implementation. Methods: This hybrid effectiveness–implementation, clustered randomized control trial (RCT) evaluates the effect of SurvivorLink among pediatric cancer survivors and their parents on receipt of follow-up cancer care. We will recruit 20 pediatric survivor clinics with half receiving the intervention and half acting as a waitlist control. Parents of survivors and survivors will complete baseline, 3 and 12 month surveys that assess SurvivorLink use, patient self-efficacy, and intentions to return for follow-up. We will use mixed methods and multi-informant assessment to assess implementation outcomes (i.e., acceptability, feasibility, appropriateness). Discussion: New approaches are needed to facilitate the receipt of long-term follow-up care among pediatric cancer survivors. This study will assess whether SurvivorLink is effective in increasing receipt of follow-up cancer care. Moreover, it will explore the influences of context and other moderators of clinical practice change in pediatric cancer survivorship.
Public Safety for Women: Is Regulation of Social Drinking Spaces Effective?

Abstract This paper examines the impact of reduced availability of hard liquor in bars on sexual crimes against women outside their homes. We construct a district level panel dataset on reported crimes and use an identification strategy that exploits a natural experiment that led to a complete crackdown on bars selling hard liquor in a state of India. Using a difference-in-differences strategy, we show that placing restrictions on alcohol sale through closure of on-premise drinking outlets that serve hard liquor reduces reported incidence of sexual assault and harassment against women but has no effect on reported rapes. We conduct placebo tests and show that the result is not driven by existing pre-trends. The result is also robust to an alternative estimation strategy using a synthetic control construction and the most conservative estimate shows a reduction in sexual assaults by 10%. These results have policy implications for regulating social drinking spaces due to their impact on women’s public safety.
Comparing the Motivational Structure and Coping Strategies in Patients with Somatoform Disorder and Normal Population

Objective: Our study was aimed to compare the motivational structure and coping strategies in patients with the somatoform disorder and normal population. Materials and methods : Ex-post facto method and random sampling method were used. The sample of this study included 60 persons, who were selected from all individuals referred to Erfan Hospital and a private clinic for somatoform disorder therapy. They were assigned to an experimental group (30 patients with the somatoform disorder; 12 with conversion disorder, 9 with somatization disorder and 9 with pain disorder), and the control group (30 healthy persons). The results were analyzed by MANOVA. Result: Motivational structure and coping strategies in patients with somatoform disorder are different from those in a normal population. Conclusion: Patients with the somatoform disorder have maladaptive motivational structure and have more focus on emotional and physical inhibitory coping strategies. As compared to normal population, they put less importance to their goals, are less hopeful in achievement and control of them, the least satisfaction from achievement or sorrow from non-achievement of goal and the least commitment to the goals. they have less freedom in selection of their goals, act very passively in the execution of their plans, and since faced a lot of failures in their life, are somehow suffering from a learned frustration and end up with this belief that effort for the achievement of their goals is in vain. When facing obstacles on their way to their goals, they abandon them and have no continuance in their way to achieve them.
Understanding Organizational Commitments in the Public Sector: A Case Study of Commissioners and Investigators at The Business Competition Supervisory Commission (KPPU)

Considering that KPPU is the only institution that handles law enforcement in the field of business competition, it is necessary to have high employee commitment and organizational strength. This study aims to explore the commitment of KPPU’s commissioner and investigator organizations. This research is a qualitative design study of a case study. The data were collected from interviews with six commissioners and twenty-one investigators. This study found that the commitment of commissioners and investigators to achieving the vision and mission in the field of law enforcement has been indicated by the emotional ties and involvement with the organization through the egalitarian principles instilled by the previous commissioners. The commitment of the commissioners and investigator is built on the agreement that the place of dedication realize ideas and contributions to the state in improving people’s welfare that is appropriate. By considering these findings, KPPU needs to strengthen its internal function of supervision to maintain high organizational ethics, integrity, and independence in performing its tasks. Considering the organizational culture, KPPU needs to build a higher levels of public service motivation to get a greater organizational commitment.
Use of Augmented Reality in Social Sciences as Educational Resource

This study investigated the effects of the use of Augmented Reality (AR) on the academic performance of students, as well as perceptions that were following the use of this new technology resource. The participants were students of primary education in Spain, which were assigned to an experimental group and a control group. Contents related to the topic Representation Earth were created, and were held with the collaboration of teachers using tablets to display bookmarks. To analyze the results collection tools of quantitative and qualitative data are used, a pre-test and post-test on the subject explained. I was done and Likert questionnaire on aspects of the use of the AR was given and an in depth interview was done teachers. Used tools of collection of data quantitative and qualitative to the deal are of a design quasi-experimental. In order to analyze the data, the statistical software SPSS 23 was used. The use of the AR as a teaching tool sheds results that reveal that the performance and the acquisition of knowledge of students improves significantly, being reflected in the ratings that were higher. The process of teaching and learning is perceived as positive, incentive and facilitator in the acquisition of knowledge.
The Design of Concurrent Dual Band Envelope Tracking Power Amplifier for Basestations

The linearity and efficiency of a transmitting system is largely determined by its last stage component: the Power Amplifier (PA). In the past century, engineers and scientists have pioneered various architectures to optimize the PA performance most notably the linearity and efficiency, as these quantities directly correspond to signal integrity and cost, respectively. In this dissertation, the design, implementation, and measurement results of a concurrent dual-band envelope tracking (ET) PA system is detailed. The dual-band PA system incorporates a new envelope tracking (ET) methodology which relaxes the large bandwidth requirement typically placed on supply modulators for dualband applications, resulting in significant efficiency improvement. Afterwards, the PA linearity optimized through the use of a new, highly stable, and scalable digital predistortion (DPD) scheme, viable for both constant supply as well as modulated supply (ET) dual-band PAs. The developed ET and multi-dimentional DPD system methodologies are then verified using a 10W peak gallium-nitride (GaN) ET PA operating with a dual-band input based on LTE and WCDMA signals, with center frequencies spaced by 310 MHz. The testbed is based on a Altera FPGA Stratix IV and two Analog Device mixed signal DPD boards. The proposed method provides a performance improvement as high as 17 dB in terms of normalized mean square error (NMSE) and 4.6 dB in terms ii of adjacent channel power ratio (ACPR) in comparison to the conventional dual-band memory polynomial method including ET.
The Geopolitics of Travel Blogging

ABSTRACT Travel blogs are an under-utilized data repository of everyday geopolitical musings. These public, longform, generally reflexive texts allow researchers to better understand how travellers narrate their own positionality and agency within limiting state structures. Geopolitics scholars of varying theoretical and topical interests can use travel blogs as data to better understand how everyday tourists and travellers ‘live geopolitics. ’ Drawing primarily from popular and feminist geopolitical insights, this paper shows how travel blogs help us to rethink questions about geopolitical authorship, especially within a digital landscape of media fragmentation. This paper also provides a case study on the geopolitical discourse of ‘border talk’ in the blogs of international volunteer teachers in Namibia.
Does it Pay to be a Multinational? A Large‐Sample, Cross‐National Replication Assessing the Multinationality‐Performance Relationship

Research Summary Does it pay to be a multinational? Despite decades of empirical research, we still do not know. We undertake a large‐sample, cross‐national replication of Lu and Beamish (2004) and Berry and Kaul's (2016) works to examine whether the multinationality–performance relationship is S‐shaped in a 2009–2016 panel of 889,865 firm‐year observations. Using a two‐stage least squares fixed‐effects model that accounts for endogeneity on a subsample of 32,835 multinationals from 64 countries, we find no evidence of an S‐shaped relationship; nor do we see it in any of the single‐country contexts. Our results show no evidence of any within‐firm effect of multinationality on performance, highlighting the need for more contextually‐grounded research focused on explaining between‐firm effects to advance our theoretical and empirical understanding of the multinationality‐performance relationship. Managerial Summary We replicate two studies that examined the relationship between a firm's multinationality and its performance. Lu and Beamish (2004) found evidence of an S‐shaped relationship—with performance first decreasing, then increasing, then decreasing again as firms expanded abroad—in a sample of Japanese firms; Berry and Kaul (2016) found no evidence of an S‐shaped pattern in a sample of U.S. multinationals. We test for the same relationship using data from nearly 250,000 firms based in over 100 countries from 2009 to 2016 and find no evidence of an S‐shaped pattern or of any effect of multinationality. Our study thus adds substantial evidence to the one shown by Berry and Kaul (2016), emphasizing the need to focus on how contextual differences influence the multinationality–performance relationship.
Optimisation of planning and delivery methods for Gamma Knife Stereotactic Radiosurgery

The work presented in this dissertation is the response to a series of technical and clinical challenges encountered during the first four years of operations in the Gamma Knife Centre at Queen Square. These challenges, which are common to most contemporary Gamma Knife centres, were prospectively addressed and practical solutions were developed for the questions they posed. The dosimetric differences between the new convolution algorithm and the standard TMR 10 algorithm traditionally used for prediction of dose distribution in Gamma Knife Radiosurgery (GKR) were explored. It was demonstrated that inhomogeneity correction with the convolution algorithm results in a considerable but consistent dose shift compared to TMR 10. No significant difference in relative dose distribution was noted and it was concluded that a reduction of the prescription dose is necessary to obtain the same absolute dosimetric effect with the convolution algorithm. The stability of the stereotactic Leksell frame G in GKR was demonstrated using a comprehensive study design that involved repeated measurements of landmarks by two observers. The study provided reliable and realistic evidence of submillimetre stability of the stereotactic frame throughout the treatment procedure which is important for evaluation and development of new frameless radiosurgery systems. The technical feasibility of using a combination of three magnetic resonance angiography sequences (triple-MRA), instead of digital subtraction angiography (DSA), for visualisation and delineation of brain Arteriovenous Malformations (AVMs) for GKR targeting was demonstrated. Target volumes obtained using triple-MRA are on average 10% smaller than AVM targets obtained with the standard DSA planning method and this can potentially reduce the risk of adverse radiation effects (ARE). The treatment planning method described here has laid the way for a change in clinical practice that favours a less invasive treatment planning approach. The same principle of less invasive AVM imaging with triple-MRA was used at the post-GKR stage, when a DSA is performed to confirm AVM obliteration. Triple-MRA was found to consistently confirm or rule out residual AVMs in patients who had undergone GKR for brain AVMs, compared to DSA, and it can also be reliably used for characterisation of residual AVMs. The use of triple-MRA as a first line for assessment of obliteration after GKR is recommended.
