Prevalence and risk factors for mental health problems and suicidal expressions among young male prisoners in Cambodia: A cross-sectional study

Background: incarceration and mental health problems are empirically known to have a strong association. Many studies have confirmed the high prevalence of mental health problems among young prisoners in particular, yet none have been conducted in Cambodia. Objectives: this study aimed first to assess the prevalence of mental health problems and suicidal expressions among young prisoners, and second, to determine the risk factors associated with these two outcomes in Cambodia. Method: a cross-sectional study among 572 young male prisoners between the ages of 15 and 24 from three prisons was conducted. Sociodemographic data and detailed information on participants’ profiles were gathered, and the Youth Self-Report (YSR) and the Attitude towards Suicide (ATTS) questionnaires were applied. Results: anxiety-depression affected 52.10% of the respondents with a similar prevalence of withdrawal depression, somatic complaints, social problems, and aggressive behaviours (around 46%). Mental health problems were strongly associated with younger age, lower educational background, and less time spent in prison. Around half (51.05%) considered life to be meaningful while 16.26% had thoughts about their own death, and 12.06% expressed wishes to die. Suicide ideation, planning, and attempts were reported by almost 6.82%, 1.75% and 2.80% of participants respectively. Prisoners who used drugs prior to imprisonment thought about death significantly more than their counterparts while suicide ideation was reported to be significantly lower among prisoners with higher education. Conclusion: the prevalence of mental health problems among young male prisoners was considerably high, while suicide expressions were reported to be lower compared to studies from other countries. This study highlights the need for implementing preventive interventions integrated into the prison health care system to im­prove the mental health of young prisoners.
The promotion of sustainability agenda for facilities management through developing knowledge capabilities

The growing awareness of sustainability issues around the world has put extensive pressure on the construction industry to improve its sustainable practice. Sustainability principles need to be applied to not just during design and construction phase but the entire life cycle of a construction project. Compared to sustainability endeavours on earlier development phases, the pace to implement sustainability agenda during the operation and maintenance phase has not been as fast during past practices of facilities management (FM). Literature study suggests that sustainable practices in FM activities can bring substantial benefits such as reducing energy consumptions and waste, while increasing productivity, financial return and standing in the community. It also suggests several barriers which inhibit the implementation of sustainability in FM practices, including the lack of knowledge, discrepancy between capability and skills, and unwillingness of the FM personnel and organizations to adapt to new routines in order to implement sustainability in their business. The capabilities of FM personnel and organizations were regarded as the key enablers in managing sustainability knowledge. In a sustainable development context, capabilities are vital to the fostering of competency in an organization to innovate in a more sustainable way and support the agenda in an organization. Additionally, research which focused on people’s capabilities and skills is still lagging behind the efforts to develop guidelines, technical manuals and knowledge portals. Therefore, it is beneficial to explore the issues of capabilities in dealing with the implementation of sustainable practices in FM. This paper introduces a research project which is aimed at establishing a knowledge capabilities framework for promoting sustainability measures in FM practices. It will explore and highlight challenges to integrate sustainability as well as the personnel and organizational capabilities that are vital in dealing with knowledge issues in implementing sustainability agenda in FM practices. The expected outcome of this research has the potential to further sustainability endeavours in FM practices, while providing a useful source of knowledge to the FM personnel and organizations.
Analysis of the Slow Floating in Grid Frequency of the Nordic Power System: Impact of Hydraulic System Characteristics

This Master's Thesis work deals with the analysis of the observed slow floating in the grid frequency of the Nordic power system. Measurements indicate that the frequency of this floating or oscillation is around 11-17 mHz. The reason for this floating is not known to this date, but it is suspected that it will increase the wear of the turbines that are providing primary regulation. In this work possible interaction between the hydraulic system and the power system has been emphasized and whether the governor settings may influence the slow floating, or not. The hydraulic models for the water conduit and turbine that are implemented in power system analysis tools are often simplified. In this Master's Thesis a hydraulic model that includes the effect of water hammer, surge tank and head loss has been implemented in the analysis tool SIMPOW. A three-machine equivalent of the Norwegian and Swedish power system has been established to study the response of the frequency after a severe disturbance. It has been demonstrated that for a severe disturbance a low-frequency mass oscillation will occur in the tunnel between the surge tank and the reservoir in the model. This will cause an oscillation in the pressure at the turbine which affects the grid frequency. The frequency of the mass oscillation depends on the construction of the tunnel and surge tank and will be different for every hydro power plant. Frequencies in the range of 5-11 mHz was found for the model used in this Thesis. It has been illustrated that with different characteristics for the two hydro power plants in the model, the floating in power system frequency will be the sum of the mass oscillations, which is assumed to be the case for the real power system. The governor parameters are found to have little influence on the damping of the low-frequency oscillations. For further work a study of the impact of several different hydro power plants in a more extensive equivalent of the Nordic power system is suggested. For this work emphasis should be on finding parameters for typical Norwegian and Swedish hydro power plants.
A survey of the statistics of marine fish catch in Indiafrom 1950 to 1962

Estimation of marine fish production is made on an all-India basis by the Central Marine Fisheries Research Institute ever since its inception, and till now brief summary reports alone showing the total landings and their composition are published regularly in the annual reports of the Institute, but details like the regional and seasonal production of the commercially important fishes and their fluctuations etc. have not so far been published. In view of the increasing attention given now for the commercial exploitation of the marine resources to augment our food supply, requests for detailed information and data on specific fisheries, both from private and public organisations are on the increase, so much so it is found necessary to publish detailed figures so that they will be readily available to all interested parties especially t8 the industry, administrator and research worker.
Prolonged Treadmill Load Carriage: Acute Injuries and Changes in Foot Anthropometry

Abstract : The objectives of this study were to: (1) determine the distribution of injuries occurring during loaded treadmill marching, (2) determine if there are significant anthropometric changes that occur in the foot during this marching, and (3) identify variables (speed, load) that may affect these injuries and foot changes. This study documented a large number of minor injuries (N equals 82) among physically fit soldiers marching on a treadmill at fast speeds and over a long distance with heavy loads. Significant pre to post foot anthropometric changes (P less than .05) were observed in ball of foot and instep circumferences with a tendency for these changes to occur with the heavier loads while ankle circumference changes occurred throughout most of the conditions. The results of this study indicate that: (1) load carriage injuries occurring during a prolonged treadmill march primarily involve the lower extremities and back, (2) foot blisters were the most common injury recorded, (3) the standard Army practice of using foot powder and undergoing frequent sock changes does not prevent blister formation during prolonged treadmill marches, (4) the most common types of back injury was upper back straining.
Collective Intentionality

Collective intentionality concerns the intentionality of groups or collectives. Intentionality is the property of being about, directed at, oriented toward, or representing objects, events, properties, and states of affairs. Examples of intentional states (states with intentionality, not just intentions) are belief, desire, hope, intention, admiration, perception, guilt, love, grief, fear, and so on. Collective intentionality involves joint, shared, or group intentionality and the intentionality of members (qua members) of groups that have joint or shared attitudes. More broadly, the study of collective intentionality concerns forms of intentionality that underpin social reality. What is distinctive about the study of collective intentionality within the broader study of social interactions and structures is its focus on the conceptual, ontological, and psychological features of joint or shared actions and attitudes, that is, actions and attitudes of (or apparent attributions of such to) groups or collectives, their relations to individual actions and attitudes, and their implications for the nature of social groups and their functioning. It subsumes collective action, intention, thought, reasoning, emotion, phenomenology, decision-making, responsibility, knowledge, trust, rationality, cooperation, competition, and related issues, and how these underpin social practices, conventions, institutions, and social ontology. The two main theoretical questions in the study of collective intentionality concern the ontology and psychology of collective agency and collective attitudes. The main ontological question is whether we should admit into our ontology group subjects of intentional states or attribute intentionality only to their members. The main psychological questions are, if we admit group subjects of intentional states, first, how to understand what they come to, whether they are the same or different than the intentional states we attribute to individuals and if different exactly how, and, second, what is special about the attitudes of individuals who participate in group action or whose attitudes underpin attributions of intentionality to groups? More specifically, can we understand what is special about the attitudes of individuals who participate in group agency or sustain the potential for group agency in terms of concepts already available in our understanding of individual agency, or must we introduce new concepts either of the modes of intending, believing, etc., or in the contents of such attitudes? Both questions concern the debate between methodological individualists and holists about the social, the first with respect to its ontology, the second with respect to its ideology.

Development and Validation of Faculty and Course Evaluations for Students for Nova Southeastern University Physical Therapy Program.

The Physical Therapy Department of Nova Southeastern University (NSU PT) changed its curriculum to problem-based learning, and in conjunction with changes needed new evaluation forms for accreditation and program requirements. The purpose of this practicum study was the development and validation of faculty and course evaluation forms for students at NSU PT. The process began with a literature review and a review of the NSU PT mission, philosophy, and accreditation documents. An internal formative committee survey was conducted, and evaluation forms were developed and validated by the summative evaluation committee of four faculty members. Items with a mean Likert score of 3.5 and above were accepted, and items below this score were reconsidered, redesigned, or excluded. Editorial recommendations were incorporated to make a final product of 5 Likert-scale forms, with 7 to 14 items each, considering affective, behavioral, psychomotor, and cognitive areas with an open-ended comment section. These forms were developed: (1) student self-assessment for the course; (2) student self-assessment for the laboratory; (3) student performance assessment for the clinic; (4) faculty tutor assessment for the course; and (5) faculty tutor assessment for the laboratory work. Recommendations are to implement these forms, conduct a pilot test, and consider longitudinal studies to track curriculum progress and aid in faculty and student development. Five appendixes include NSU PT mission statements, a list of committee members, the formative committee questionnaire, the summative committee questionnaire, and the five forms of the evaluation product.

Delay-Optimal Edge Caching With Imperfect Content Fetching via Stochastic Learning

Caching popular contents in close proximity to the users can effectively reduce the latency in communication systems. Considering the imperfect content fetching from the original server, the caching management at the edge node should be determined according to not only the content popularity but also how difficult to fetch these content objects from their corresponding original servers. In this paper, we study the edge caching for minimizing the long-term average delay, where the fetching delay of the uncached contents is introduced. We construct a decision-theoretic framework for this delay-optimal content-caching problem, where the main obstacle is that the consideration of the imperfect content fetching breaks the Markovian property in the decision-theoretic framework. To overcome this obstacle, by analyzing the queue dynamics within the content fetching delay after the content object is removed from the cache, we transform the problem for meeting the Markovian property, and model it as an infinite horizon semi-Markov decision process (SMDP). Achieving the delay optimality of the caching problem needs to solve the Bellman equation of the SMDP, but it leads to the curse of dimensionality. We decompose the global optimality equation into several per-content optimality equations, and propose a low-complexity delay-optimal content caching algorithm by stochastic learning for each content. Finally, the simulation results show that our proposed algorithm achieves significantly lower delay than conventional caching algorithms.
Development of an Experimental Phased-Array Feed System and Algorithms for Radio Astronomy

Development of an Experimental Phased Array Feed System and Algorithms for Radio Astronomy Jonathan C. Landon Department of Electrical and Computer Engineering, BYU Doctor of Philosophy Phased array feeds (PAFs) are a promising new technology for astronomical radio telescopes. While PAFs have been used in other fields, the demanding sensitivity and calibration requirements in astronomy present unique new challenges. This dissertation presents some of the first astronomical PAF results demonstrating the lowest noise temperature and highest sensitivity at the time (66 Kelvin and 3.3m/K, respectively), obtained using a narrowband (425 kHz bandwidth) prototype array of 19 linear co-polarized L-band dipoles mounted at the focus of the Green Bank 20 Meter Telescope at the National Radio Astronomy Observatory (NRAO) in Green Bank, West Virginia. Results include spectral line detection of hydroxyl (OH) sources W49N and W3OH, and some of the first radio camera images made using a PAF, including an image of the Cygnus X region. A novel array Y-factor technique for measuring the isotropic noise response of the array is shown along with experimental measurements for this PAF. Statistically optimal beamformers (Maximum SNR and MVDR) are used throughout the work. Radio-frequency interference (RFI) mitigation is demonstrated experimentally using spatial cancelation with the PAF. Improved RFI mitigation is achieved in the challenging cases of low interference-to-noise ratio (INR) and moving interference by combining subspace projection (SP) beamforming with a polynomial model to track a rank 1 subspace. Limiting factors in SP are investigated including sample estimation error, subspace smearing, noise bias, and spectral scooping; each of these factors is overcome with the polynomial model and prewhitening. Numerical optimization leads to the polynomial subspace projection (PSP) method, and least-squares fitting to the series of dominant eigenvectors over a series of short term integrations (STIs) leads to the eigenvector polynomial subspace projection (EPSP) method. Expressions for the gradient, Hessian, and Jacobian are given for use in numerical optimization. Results are given for simulated and experimental data, demonstrating deeper beampattern nulls by 6 to 30dB. To increase the system bandwidth toward the hundreds of MHz bandwidth required by astronomers for a fully science-ready instrument, an FPGA digital backend is introduced using a 64-input analog-to-digital converter running at 50 Msamp/sec and the ROACH processing board developed at the University of California, Berkeley. International efforts to develop digital back ends for large antenna arrays are considered, and a road map is proposed for development of a hardware correlator/beamformer at BYU using three ROACH boards communicating over 10 gigabit Ethernet.
New Markov Decision Process Formulations and Optimal Policy Structure for Assemble-to-Order and New Product Development Problems

This thesis examines two complex, dynamic problems by employing the theory of Markov Decision Processes (MDPs). Chapters 2 and 3 consider assemble-to-order (ATO) inventory systems. An ATO system consists of several components and several products, and assembles products as demand is realized; it is becoming increasingly popular since it provides greater flexibility in manufacturing at a reasonable cost. This work contributes to the ATO research stream by characterizing optimal inventory replenishment and allocation policies. Chapter 4 examines the new product development (NPD) process with scarce resources and many projects in parallel, each lasting several periods, in the face of uncertainty. This study advances the NPD literature by revealing that optimal project selection and resource allocation decisions are congestion-dependent. Below, I elaborate on the novel optimal policies and structural results I obtain using MDP formulations, which is the overarching theme of the thesis. In Chapter 2, I consider generalized ATO “M -systems” with multiple components and multiple products. These systems involve a single “master” product which uses multiple units from each component, and multiple individual products each of which consumes multiple units from a different component. Such systems are common for manufacturers selling an assembled product as well as individual spare parts. I model these systems as infinite-horizon MDPs under the discounted cost criterion. Each component is produced in batches of fixed size in a make-to-stock fashion; batch sizes are determined by individual product sizes. Production times are independent and exponentially distributed. Demand for each product arrives as an independent Poisson process. If not satisfied immediately upon arrival, these demands are lost. Therefore the state of the system can be described by component inventory levels. A control policy specifies when a batch of components should be produced (i.e., inventory
DEFORMATION MEASUREMENTS WITH INCLINOMETERS

Inclinometers have steadily gained widespread use for measuring deformations in landslides, natural slope creep, temporary excavations, earth and rock embankments, slurry walls, shafts, tunnels, lateral pile movements, and settlements beneath tanks, fills, and foundations. Inclinometer data can be used to determine displacement magnitude and rate and the location of the zone of displacement, as well as the absolute position of the inclinometer casing in the ground. High-precision inclinometers today utilize servo-accelerometer sensors in a uniaxial or biaxial configuration, mounted inside a waterproof wheel carriage. The most common is the traversing borehole type, where the wheels are oriented and guided by specially made grooved casing. Fixed-in-place inclinometers employ the same guide casing but are used infrequently due to high cost. Inclinometer monitoring is one of the most labor- and data-intensive geotechnical measuring activities. In addition to straightforward data reduction, many errors have to be identified and dealt with before results can be presented and correctly interpreted. In the authors' experience, many inclinometer monitoring programs have failed to yield good results because errors were not recognized. In this paper, guidance is given to the reader regarding inclinometer system design, installation, monitoring, data processing, and sources of errors and their resolution. Accuracy of the inclinometer is highly dependent on the equipment selected, the method by which it is installed in the ground, monitoring techniques, correct scrutiny of the data, and ability to correct instrument errors. A servo-accelerometer-type system is capable of a precision of plus or minus 0.05 to 0.25 in. over 100 ft when the casing is vertical or horizontal. The best results are achieved when cooperation and understanding between engineers, clients, and contractors provide continuity in the total monitoring process.
