Family Experiences and Feedback: An Examination of Attrition in Parent-Child Interaction Therapy

ABSTRACT Attrition is a significant problem in child psychotherapyand has serious implications for overall treatment effectiveness. Predictors of attrition include those at the client, therapist, and treatment levels. The current study investigated factors associated with attrition in Parent-Child Interaction Therapy (PCIT), an evidence-based parent training program for families with young children with disruptive behavior disorders. The sample of 67 caregivers were treated by 25 therapists from 19 different licensed psychiatric outpatient clinics across one state and were part of a larger study (RO1 MH09750; PI: Herschell). The effects of caregivers’ attitudes toward therapy, expectations of therapy, perceived therapist cultural competence, and commitment to treatment were examined using Binomial Logistic Regression. Therapy expectations and commitment to treatment added significantly to the model predicting attrition. Fleiss’ kappa was used to examine caregiver-therapist agreement on completion status, reasons PCIT ended, barriers to treatment experienced by families, and caregiver compliance with post-treatment therapist referrals. Results suggest low agreement across each variable, indicating that therapists may not be aware of caregiver barriers or reasons they leave PCIT prematurely. Limitations, suggestions for future research, and clinical implications are discussed.
Numerical investigations on non-synchronous vibration and frequency lock-in of low-pressure steam turbine last stage

The flow phenomenon of rotating instability (RI) and its induced non-synchronous vibrations (NSV) in the last stage have gradually become a security problem that restricts the long-term flexible operations of modern large-scaled low-pressure steam turbines. Especially, if one structural mode of the last stage moving blade (LSMB) is excited, significant blade vibrations may potentially lead to high-cycle fatigue failure. A loosely coupled computational fluid dynamics reduced model with prescribed blade vibrations has been established to investigate NSV of the LSMB and the potential lock-in phenomenon under low-load conditions. Firstly, calculations with reduced multi-passage domain have been verified by comparing with the results of the full-annulus one, and an appropriate reduced domain is determined. Secondly, a set of calculations by controlling blade vibration parameters indicate that lock-in phenomenon between RI frequency and blade vibration frequency may occur when nodal diameters of cascade vibrations is coincident with the wave number of RI. Furthermore, dynamic modal decomposition technology has been employed to identify the unsteady pressure field around the blade surface and to reveal the interaction relationship between the flow modes of RI and vibration-induced pressure disturbance. Finally, the blade response evaluation based on harmonic analysis shows that in NSV, the global maximum dynamic response level of locked-in case is nearly 20 times than that of unlocked one.
Biophotonic MEMS for single molecule detection and manipulation

The development of biophotonic MEMS for single molecule detection (SMD), manipulation and optical trapping is presented. Integrated cyclic Si/sub x/N/sub y/ microfluidic devices with microelectrodes are fabricated with surface micromachining techniques. Microfluidic channels in the optical windows consist of just Si/sub x/N/sub y/ membrane without substrates. Capability of SMD, manipulation and optical trapping are demonstrated with the Si/sub x/N/sub y/ membrane channels. Such a device can be used in high throughput screening bioassay chips, which require multiplexed processing, SMD, and manipulation capability. Compared with earlier works on microfluidic devices formed by bonding two-glass substrates or polymers, our multiplexed design has attractive features such as bondless nano- and microfluidic channels, low transmission loss, and high stability to temperature and chemicals. The advanced biophotonic MEMS will have characterization and multiple manipulation tools for high-resolution spectroscopic analysis, robotic controls, and microscale lab automations on a chip.
Overset Euler/Boundary-Layer Solver with Panel-Based Aerodynamic Modeling for Aeroelastic Applications

An Euler solver with boundary-layer option, overset/sheared Cartesian mesh, and automated mesh-generation capability has been developed for aeroelastic applications to complex aircraftlike configurations. The automated mesh-generation scheme can automatically generate a block mesh by extending the grid lines from surface meshes to the entire flowfield. In this way, the surface mesh can adopt the paneling definition required by commonly practiced aerodynamic panel methods as input. The overset/sheared-Cartesian-mesh capability allows convenient modeling of very complex configurations, such as an aircraft with external stores, in which the aircraft and stores are modeled by different blocks of meshes. This paper does not describe a novel computational method nor provide new insight into the characteristics of physical problem. Rather, it offers a user-friendly and cost-effective computational methodology that can be readily adopted by industry for rapid aeroelastic applications.
Model Inaccuracy Analysis and Compensation of Stationary Frame-Based Deadbeat Predictive Current Control for High-Speed PMSM Drives

Due to explicit modeling of delay effects and fast dynamic response, the recently reported stationary frame-based deadbeat predictive current control (DBPCC) is particularly attractive for high-speed permanent magnet synchronous machine (PMSM) drives. However, its actual control performances would be heavily dependent on model accuracy. Therefore, this article presents an analytical and systematical investigation into the influences of model inaccuracy on the stationary frame-based DBPCC. Steady-state and transient performance degradations under machine parameter mismatches and inverter nonlinearity over the whole speed range have been studied. Importantly, the analyses show that the steady-state control errors will increase greatly under parameter mismatch as the speed rises; while the transient current tracking errors, only caused by inductance mismatch, can be quickly suppressed after two time-steps. To further improve the parameter robustness of the stationary frame-based DBPCC for high-speed drives, this article also proposes a simple but effective method, called adaptive reference correcting current injection (ARCCI). The proposed method can effectively eliminate all the steady-state current errors caused by model inaccuracy. It can be easily implemented and applicable at high speeds with low switching-to-fundamental frequency ratios (SFRs) as well. Both the presented analyses and compensation methods have been validated by extensive simulations and experiments.
Awareness and usage of information standards in the uk construction industry: a survey by the SIENE network

Developments in information standards and interoperability in the construction industry are becoming increasingly popular. Much of this development is centred on the Internet for sharing of information and generic data exchange. However many industry participants are unaware of the benefits of information standards and reluctant to make long-term investment on them unless there is clear evidence of business benefits. The Network on Information Standardisation, Exchanges and Management in Construction (SIENE) was launched in March 2000 to streamline information standardisation and interoperability in the construction industry. It is an international network consisting of academics and industry practitioners in the UK and elsewhere whose work on the subject is of international reputation. The project is funded by The Engineering and Physical Sciences Research Council (EPSRC) under The Innovative manufacturing Initiative (IMI). The main source of knowledge gathering is through workshops conducted in the UK. The website of SIENE also provides opportunity for the members and other participants to enhance the knowledge base of the network. SIENE’s main objective is to explore current research being undertaken in the area of information standardisation and to benchmark UK performance with the rest of the world. It has also conducted workshops to investigate sources and types of barriers that prevent the adoption of information standards and to identify business benefits for construction firms. The findings of the project will be disseminated amongst industry and academia. The paper deals with the results of a questionnaire survey conducted by SIENE in the UK on awareness and usage of information standards among contractors, consultants, suppliers and clients in the construction industry. Forty members of the Construct IT, Centre of excellence in UK were selected as the initial target audience for the questionnaire survey. It is expected to broaden the scope of the survey to a wider audience in its second stage. The paper will discuss the information standards, which are widely being used in the UK construction industry and will highlight any organisational problems, which hinder the adoption of standards. It will also propose areas, which need to be improved for the firms in the industry to gain business benefits.
EFFECT OF SOME GROWTH REGULATORS APPLIED TO A MULTIPLICATION AND ROOTING MEDIA ON MICROPROPAGATION AND ACCLIMATIZATION OF SOME CULTIVARS OF Rosa hybrida L.

The present research was carried out to study the effect of BAP at 0.25, 0.50, 1.00 and 2.00 mg/l concentrations added to the multiplication medium and IAA at 0.1, 0.3, 1.0 and 3.0 mg/l concentrations applied in rooting medium on the in vitro micropropagation and acclimatization under greenhouse conditions of Rosa hybrida L. plants. The rose cultivars used in this research were namely Athena, Diana and Red Success. To evaluate the adaptation degree of different rose cultivars to culture medium composition, the shoot tips (15 – 20 mm length) were surface sterilized and cultured on the modified Quoirin & Lepoivre (1977) medium used as proliferation medium supplemented with casein hydrolysate (1.0 g/l), sucrose (30.0 g/l), Difco agar (8.0 g/l), gibberellic acid (GA3) (1.0 mg/l), BAP (1.0 mg/l) and IAA (0.3 mg/l). The proliferated shoots were excised and cultured on multiplication and rooting media. The obtained results indicated that Red success rose cv. were the best to produce the highest rate of shoot proliferation, shoot multiplication, rhizogenesis values and survival percentage followed by Diana rose cv. , while Athena rose was the lowest in this respect. The obtained results showed that the best shoot multiplication was achieved in the culture medium containing 6-benzylaminopurine (BAP) (1.0 mg/l) and indole-3acetic acid (IAA) (0.5 mg/l) which produced the highest survival percentage, shoot initiation occurred within a few days, the highest percentage of explants which formed shoots, the highest number of multiplied shoots and the tallest multiplied shoots per explant. The obtained results also indicated that the BAP concentration of the shoot multiplication medium affected rooting and survival percentages in the next stage of culture. Shoot tips formed on media which containing 0.25 and 0.50 mg/l BAP rooted and acclimatized better than shoot tips formed on media containing 1.0 and 2.0 mg/l BAP. Moreover, rooting of multiplied shoots was achieved on the same medium used in multiplication stage except for the macroelements of Quoirin & Lepoivre (1977) medium used at half strength and sucrose at 20 g/l and IAA (0.3 mg/l) which produced the highest rooting percentage, the highest number of roots per explant and the tallest roots per explant. The obtained results also revealed that fewer amount of IAA (0.1 mg/l) in the rooting media significantly improved plantlets acclimatization, and subsequently transferred to a mixture of peatmoss and perlite (3:1 v/v) to greenhouse. The rooted plantlets survived Successfully and grew into normal plants.
Hierarchical architecture of active knits

Nature eloquently utilizes hierarchical structures to form the world around us. Applying the hierarchical architecture paradigm to smart materials can provide a basis for a new genre of actuators which produce complex actuation motions. One promising example of cellular architecture—active knits—provides complex three-dimensional distributed actuation motions with expanded operational performance through a hierarchically organized structure. The hierarchical structure arranges a single fiber of active material, such as shape memory alloys (SMAs), into a cellular network of interlacing adjacent loops according to a knitting grid. This paper defines a four-level hierarchical classification of knit structures: the basic knit loop, knit patterns, grid patterns, and restructured grids. Each level of the hierarchy provides increased architectural complexity, resulting in expanded kinematic actuation motions of active knits. The range of kinematic actuation motions are displayed through experimental examples of different SMA active knits. The results from this paper illustrate and classify the ways in which each level of the hierarchical knit architecture leverages the performance of the base smart material to generate unique actuation motions, providing necessary insight to best exploit this new actuation paradigm.
Performance Monitoring Fundamentals: Demystifying Performance Assessment Techniques

Real-time performance monitoring to identify poorly or under-performing loops has become an integral part of preventative maintenance. Among others, rising energy costs and increasing demand for improved product quality are driving forces. Automatic process control solutions that incorporate real-time monitoring and performance analysis are fulfilling this market need. While many software solutions display performance metrics, however, it is important to understand the purpose and limitations of the various performance assessment techniques since each metric signifies very specific information about the nature of the process. This paper reviews performance measures from simple statistics to complicated modelbased performance criteria. By understanding the underlying concepts of the various techniques, readers will gain an understanding of the proper use of performance criteria. Basic algorithms for computing performance measures are presented using example data sets. An evaluation of techniques with tips and suggestions provides readers with guidance for interpreting the results.
Prescription Drug and Cannabis Use among Recent Latinx Immigrants Pre- and Post-Immigration to the US

ABSTRACT Introduction: Shifts in the sociopolitical context of Latin America have led to steep increases in recent Latinx immigrants (RLI) arriving in the US within the context of forced migration. Yet, little is known about how adverse experiences of RLIs before and after immigration may impact their health including drug use. The purpose of this study was to examine prescription drug and cannabis use before and just after immigration among RLIs and how this drug use is influenced by pre-and post-immigration factors. Methods: This study utilized baseline data from a study examining pre- to post-immigration drinking and driving trajectories among RLI in the United States (US). Baseline criteria included: self-identifying as a Latinx immigrant, 18 − 34 years old, who recently immigrated from a Latin American country. Multivariate logistic regression was conducted to determine predictors of drug use both prior to and after immigrating. Results: There were 540 RLI, 50.2% male and 47.8% subjected to forced migration. Prescription and illicit drug use decreased post-immigration with sedatives being the most common. Higher levels of education was associated with increased odds of pre-immigration prescription drug use and cannabis use. Those experiencing forced migration were more likely to engage in prescription drug use before and after immigration, while no associations were found for cannabis use. Conclusion: Findings suggest a need for increased substance use and mental health services among RLIs arriving within the context of forced migration. More research is needed to understand the trajectories of drug use among RLI as their time in the US increases.
Eliciting agents’ behaviour and model validation using role playing game in agent-based dairy supply chain model

Abstract Role playing games have been widely used to develop and validate an agent-based model by observing players’ behaviour. Our study focuses on proposing a novel approach to use role-playing games in the development and validation of an agent-based model. Our innovations include matching the game’s parameters and player composition to reality, incorporating the design of experiments into the data collection, and incorporating operational validation steps into the process. We demonstrate the benefits of our approach by a case study of a dairy supply chain. Our analysis illustrates that the data obtained from the role playing game are valuable for the validation of agent-based models at the micro-level (process and knowledge representation) and, subsequently, improve the validity of the model at the macro-level.
Estimation of Inertia for Synchronous and Non-Synchronous Generators Based on Ambient Measurements

The inertia information of both synchronous generators (SGs)/equivalent SGs and converter interfaced generators (CIGs) are crucial to maintain the frequency stability of modern power grids. This paper proposes a novel data-driven method using ambient measurements, which seems to be the first method that can estimate the inertia constants of SGs/equivalent SGs and the virtual inertia constants of CIGs simultaneously without disturbing the system’s normal operating condition. Numerical studies in the IEEE 68-bus system demonstrate that the developed estimation method can estimate the inertia constants of different generation units accurately and is robust to measurement noises, missing measurements and the variation of operating conditions.
Perceived Physical and Psychological Health in Middle Adulthood : Links to Marital Satisfaction, Age of Marriage, and SES

Background: The life course health development approach, as a new theoretical model relating to health, dwells on psychosocial factors as well as biological factors, and it proposes that the effects of developmental timing unfolding over one’s lifespan should be considered. Based on this theoretical model, as well as empirical studies relating to marriage and health, one of the psychosocial factors that may contribute to the health of middle-aged individuals is the marital relationship. Aims: The aim of this study – conducted with individuals in middle adulthood – is to investigate the relationships between marital satisfaction, age at the time of marriage, SES (socioeconomic status) and psychological and physical health. Method: Data was collected from middle-aged individuals between 40–69 years in Turkey (160 women and 142 men). The World Health Organization Quality of Life Measurement Tool, Brief Symptom Inventory, Marriage Life Scale, and a Demographic Information Form were used to assess the participants’ perceived physical and psychological health, their marital satisfaction, their age of marriage, and SES. Results: A path analysis indicated that the age of marriage was positively related, and perceived psychological health problems were negatively related to perceived physical health. Both marital satisfaction and SES were negatively related to perceived psychological health problems. Upon examination of the mediator role of psychological health problems and SES, it was observed that both marital satisfaction and SES were related to perceived physical health through perceived psychological health problems. Also, the age of marriage was related to perceived psychological health problems via SES. Conclusion: The findings showed that marriage is an important component in the evaluation of perceived health in middle age; individuals are healthier when they get married at a more mature age and have a positive marital relationship.
Investigation of the suitability of commercially available bio-oils as insulating liquid

This paper deals with investigations on usability of commercially available bio-oils as insulating liquid. The bio-oils investigated are those that are "in general not hazardous to water" according to German General Administrative Regulation on the Classification of Substances Hazardous to Waters. The oils tested by us meeting this criteria are predominantly biodegradable hydraulic fluids of low viscosity. Besides the ecological advantages, these oils have. excel lent resistance to ageing, sound fluidity, low pour point and high flash point. In order to explore possible field of application of bio-oils as insulating material, dielectric tests according to IEC 156 and IEC 247 have been carried out. Tests included measurement of AC breakdown strength as well as dielectric dissipation factor tan /spl delta/, permittivity /spl epsiv//sub r/ and specific DC resistance /spl rho/. Obtained results are compared to the electrical properties of inhibited rape-seed oil RAPSOL T, which is suitable as transformer oil substitute based on our earlier reported investigations. This work has led to identification of a commercially available bio-oil whose electrical characteristics are equal or even better than that of RAPSOL T.
Feasible Power-Flow Solution Analysis of DC Microgrid Considering Distributed Generations Under MPPT Control

For a DC microgrid with constant power loads (CPLs), the existence of a feasible power-flow solution, which is usually difficult to analyze, is a necessary condition for the correct operation of systems. In this paper, the solvability of power-flow equation of DC microgrid with CPLs is analyzed, where a majority of distributed generations (DGs) are under MPPT control while other DGs are under droop control. At first, this paper builds a power-flow mathematical model of the DC microgrid. Secondly, three solvability conditions are proposed with the first one being applied to ensure the power-flow equation has a solution, while the other two applying to ensure the solution within the given voltage deviation. The first analytical condition (<xref ref-type="theorem" rid="theorem2">Theorem 2</xref>) is obtained by applying Brouwer fixed-point theorem. Compared with the existing results, this obtained sufficient condition is less conservative. Furthermore, the other two sufficient solvability conditions (<xref ref-type="theorem" rid="theorem3">Theorems 3</xref> and <xref ref-type="theorem" rid="theorem4">4</xref>) can guarantee the equilibrium not only exists, but also the voltage deviation is within an acceptable range. Finally, case studies verify the correctness of the proposed theorems. The obtained conditions provide a guidance for establishing a dependable DC microgrid.
Initial metrics and pilot program results for measuring the performance of the Canadian construction industry

A study has been initiated by the Canadian Construction Innovation Council to support the measurement of the performance of the Canadian construction industry. Metrics have been established to cover aspects of cost, time, scope, quality, safety, innovation, and sustainability. The metrics were piloted with industry partners and applied to institutional building and infrastructure projects. The metrics were selected in recognition of other national and international efforts in benchmarking and with a view of supporting analysis at the project, organization, and industry level. The experience gained through the pilot project indicates that the metrics are reasonably well understood in their definition. While the cost, time, scope, and safety information is readily available, as expected, the information for quality innovation and sustainability is not or requires more detailed in-person interviews of project participants to obtain a complete picture of project performance. The data analysis and presentation.
