Degree or examination: What is the foundation of the social work workforce in China?

The current Chinese social work licensure program does not mandatorily require formal social work education. This compromised policy is contradictory to the mission of formal social work education and the trajectory of professionalization in other Western countries. This study examined whether social work graduates differ from those who do not have formal social work education in terms of competency, commitment, and turnover intention. Results described the struggles of social work graduates in their experiences in the field. The diminishing role of formal social education may affect the professional identity of social workers in social work development in China.
The Clusters AgeS Experiment (CASE): RR Lyrae variables in the globular cluster NGC 6362

ABSTRA C T We present V- and B-band charge-coupled device (CCD) photometry of 35 RR Lyr stars in the Southern hemisphere globular cluster NGC 6362. Fourier decomposition of the light curves was used to estimate the basic properties of these variables. From the analysis of the RRc stars we obtain a mean mass Ma 0:531 ^ 0:014 M(; luminosity log L=L(a 1:656 ^ 0:006; effective temperature T effa 7429 ^ 20 and helium abundance Ya 0:292 ^ 0:002: The mean values of the absolute magnitude, metallicity (on Jurcsik’s scale) and effective temperature for 14 RRab stars with ‘regular’ light curves are: MV a 0:86 ^ 0:01;âFe=Haa 20:93 ^ 0:04 and T effa 6555 ^ 25; respectively. From the B 2 V colours, periods and metallicities of the RRab stars we estimate the colour excess for NGC 6362 to be equal to EOB 2 VUa0:08 ^ 0:01: Using this value we derive the colours of the blue and red edges of the instability strip in NGC 6362 to beOB 2 VU BE a 0:17 andOB 2 VU RE a 0:43: From the relations between the Fourier coefficients of RRab and RRc stars and their absolute magnitudes we estimate the apparent distance modulus to NGC 6362 to be Om 2 MUV a 14:46 ^ 0:10: From the mean value of log L=L( of the RRc stars we obtain 14:59 ^ 0:03: The V-band light curves of three of the RRc stars exhibit changes in amplitude of over 0.1 mag on the time-scale of around one week. Near the radial first overtone frequency we find one or two peaks, which strongly suggests that these variables belong to the newly identified group of non-radial pulsating RR Lyr stars.
On the metrical theory of continued fractions

Suppose bk denotes either 0(k) or q(Pk) (k = 1, 2, **.) where the polynomial 0 maps N to N and Pk denotes the kth rational prime. Suppose (Ck(X))00I denotes the sequences of partial quotients of the continued function expansion of the real number x. Then for certain functions F: R>0 -R we show that lim F'l [F(cb,(x))+ + F(cbk(x))] F I [ 1 f' F(cI(x)) N-oo L N J [(log2) o 1 +x J almost everywhere with respect to Lebesgue measure. This result with bk = k is classical and due to Ryll-Nardzewski. In this note we consider the continued fraction expansion of a real number
2 , 3-dioxygenase , and tryptophan catabolism

Interferons have been shown to be potential anti-cancer agents and to inhibit tumor cell growth in culture. The in vivo mechanism of the anti-proliferative effect may be direct or indirect through the immune system; however, in vitro a primary mechanism of cytotoxicity is through the depletion of tryptophan. In particular, interferon-7 (IFN-y) induces an enzyme of tryptophan catabolism, indoleamine 2,3-dioxygenase (IDO), which is responsible for conversion of tryptophan and other indole derivatives to kynurenine. The inhibitory effect of interferon on many intracellular parasites such as Toxoplasma gondii and Chiamydia trachomatis is by the same mechanism. Elevated kynurenine levels have been found in humans in a number of diseases and after interferon treatment, and the enzyme is induced in rodents after administration of interferon inducers, or influenza virus. IDO induction also occurs in vivo during rejection of a! logeneic tumors, indicating a possible role for this enzyme in the tumor rejection process. The gene for IDO has been cloned and shown to be differentially regulated by IFN-a and IFN-y. IDO induction has been correlated with induction of GTP-cyclohydrolase, the key enzyme in pteridine biosynthesis. A direct role for IDO in pteridine synthesis has not been shown, and this parallel induction may reflect coordinate regulation of genes induced by IFN-y. A possible role for IDO in 02-radical scavenging and in inflammation is discussed. -Taylor, M. W. ; Feug, G. Relationship between interferon-y, indoleamine 2,3-dioxygenase, and tryptophan catabolism.

Chemosensory influences on eating and drinking, and their cognitive mediation

This book explores how sensations can be used in modifying nutritional disorders. The first section addresses sensory deficiency (or excess) states and how they affect nutritional states. It includes chapters on olfaction, gustation, retronasal olfaction, vision, hearing and vestibular function, as well as somatosensory and tactile nature. The second section examines the use of the sensory system to treat nutritional disorders including anorexia, cachexia, and obesity. The book focuses on the mechanisms of sense of smell and taste and how they influence on satiety and weight.
Uniqueness of the Surface-Wave Speed: A Proof That Is Independent of the Stroh Formalism

It is well-known in surface-wave theory that the secular equation for the surface-wave speed v can be written as det M = 0 in terms of the surface impedance matrix M. It has recently been shown by the present authors that M satisfies a simple algebraic Riccati equation. It is shown in the present paper that a purely matrix algebraic analysis of this equation suffices to prove that whenever a surface wave exists it is unique.

We outline several proposals for astrophysical and cosmological tests of quantum theory. The tests are motivated by deterministic hidden-variables theories, and in particular by the view that quantum physics is merely an effective theory of an equilibrium state. The proposed tests involve searching for nonequilibrium violations of quantum theory in: primordial inflaton fluctuations imprinted on the cosmic microwave background, relic cosmological particles, Hawking radiation , photons with entangled partners inside black holes, neutrino oscillations, and particles from very distant sources.
Private Approximation of the Set Cover Problem

Private approximation, introduced by Feigenbaum, Ishai, Malkin, Nissim, Strauss, and Wright, allows us to find approximate solutions with disclosing as little information as possible. In STOC 2006, Beimel, Carmi, Nissim, and Weinreb studied the private approximation for both the vertex cover and the max exact 3SAT problems. In this paper, we consider the set cover problem where the costs of all sets are polynomially bounded. We show that there exists neither a deterministic nor a randomized private approximation. We also consider the case that the frequencies of all elements are equal. We show that in this case there exist no deterministic private approximation.
Impulsivity and the 5-HTTLPR Polymorphism in a Non-Clinical Sample

Background Impulsivity has been associated with serotonergic system functions. However, few researchers have investigated the relationship between a polymorphism in the promoter of the serotonin transporter gene (5-HTTLPR) and the different components of impulsivity in a non-clinical population. The aim of this study was to investigate the relationship between a polymorphism in the promoter region of the serotonin transporter gene (5-HTTLPR) and the different components of impulsivity in a non-clinical population. Methodology/Principal Findings We administered two neuropsychological tests, the Continuous Performance Task and the Iowa Gambling Task, to 127 healthy participants to measure their levels of motor, attentional and non-planning impulsivity. Then, these participants were grouped by genotype and gender, and their scores on impulsivity measures were compared. There were no significant differences between group scores on attentional, motor and non-planning impulsivity. Conclusions/Significance Our results suggest that 5-HTTLPR genotype is not significantly associated with subsets of impulsive behavior in a non-clinical sample when measured by neuropsychological tests. These findings are discussed in terms of the sensitivity of neuropsychological tests to detect impulsivity in a non-clinical population and the role of gender and race in the relationship between the 5-HTTLPR and impulsivity.
History of multiple suicide attempts as a behavioral marker of severe psychopathology.

OBJECTIVE Individuals with a differing number of past suicide attempts are generally considered a homogeneous group, despite emerging evidence to the contrary. The current study aimed to test the hypothesis that multiple suicide attempters would exhibit a more severe clinical profile than single suicide attempters. METHOD A series of self-report batteries and clinical interviews was administered to 39 single attempters and 114 multiple attempters who came to an urban hospital emergency room after a suicide attempt. The participants were predominantly poor and nonwhite. RESULTS Multiple suicide attempters versus single attempters exhibited a greater degree of deleterious background characteristics (e.g., a history of childhood emotional abuse, a history of family suicide), increased psychopathology (e.g., depression, substance abuse), higher levels of suicidality (e.g., ideation), and poorer interpersonal functioning. Profile differences existed even after control for borderline personality disorder. CONCLUSIONS Results indicate that multiple attempters display more severe psychopathology, suicidality, and interpersonal difficulties and are more likely to have histories of deleterious background characteristics than single attempters. Moreover, these differences cannot be explained by the diagnosis of borderline personality disorder. Results suggest that the identification of attempt status is a simple, yet powerful, means of gauging levels of risk and psychopathology.
Joint spectral-temporal spectrum prediction from incomplete historical observations

Spectrum prediction is a promising technology to infer unknown/unmeasured spectrum state from known/measured spectrum data, by exploiting the inherent correlations among them. This paper investigates spectrum prediction from a spectral-temporal two-dimensional perspective, with the primary objective to improve the prediction performance by jointly exploiting the correlations in both time and frequency domains. Moreover, a practical constraint is also considered that historical observations could be highly incomplete, due to hardware limitations and/or transmission loss. To tackle these unique challenges, we firstly study the spectral and temporal correlations in real-world spectrum measurement data. Then, we formulate the joint spectral-temporal spectrum prediction with incomplete historical observations as a matrix completion problem. To resolve this problem, a soft-impute algorithm is further introduced by leveraging the approximate low intrinsic-dimensionality of real-world spectrum data matrix. Numerical results confirm the effectiveness of the proposed scheme and demonstrate that it outperform state-of-the-art schemes.
Mode-locking phenomena of external cavity lasers

Mode-locking characteristic of hybrid soliton pulse source (HSPS) utilizing linearly chirped raised-cosine flat top apodized fiber Bragg grating (FBG) is investigated by using coupled-mode equations. It is found that proper mode-locking range where transform-limited pulses are generated is increased up to 1.3 GHz by using linearly chirped raised-cosine flat top apodized FBG instead of linearly chirped Gaussian apodized FBG giving a mode-locking range of 850 MHz
Modelling the delay distribution of Binary Spray and Wait routing protocol

This article proposes a stochastic model to obtain the end-to-end delay law between two nodes of a Delay Tolerant Network (DTN). We focus on the commonly used Binary Spray and Wait (BSW) routing protocol and propose a model that can be applied to homogeneous or heterogeneous networks (i.e. when the inter-contact law parameter takes one or several values). To the best of our knowledge, this is the first model allowing to estimate the delay distribution of Binary Spray and Wait DTN protocol in heterogeneous networks. We first detail the model and propose a set of simulations to validate the theoretical results.
Testing Intertemporal Substitution, Implicit Contracts, and Hours Restriction Models of the Labor Market Using Micro Data

We present new tests of three theories of the labor market: intertemporal substitution, hours restrictions, and implicit contracts. The intertemporal substitution test we implement is an exclusion test robust to many specification errors and we consistently reject this model. We model hours restrictions as part of an endogenous switching model. We compare the implicit probit equation to an unrestricted probit equation for unemployment and reject the hours restriction model. For the implicit contracts model, we estimate nonseparable within-period labor-supply and consumption equations. We test a cross-equation restriction of the model and cannot reject the implicit contracts model. (JEL E30, J22, J60)
Implementation of real-time pedestrian detection on FPGA

Every year, many pedestrians are killed or seriously injured due to car accidents. A pedestrian recognition and warning system could save lives by warning the driver about a possible pedestrian hazard. Although significant progress in research for such systems has been reported, these systems are yet to be implemented in vehicles. In this paper, we review some major pedestrian detection systems and identify the challenges that a real-time pedestrian recognition system has to overcome. We also discuss some positive experimental results using a modified pedestrian detection algorithm that is suitable for implementation on a Field Programmable Gate Array (FPGA) platform.
Evolution of Well-Being and Happiness After Increases in Consumption of Fruit and Vegetables.

OBJECTIVES To explore whether improvements in psychological well-being occur after increases in fruit and vegetable consumption. METHODS We examined longitudinal food diaries of 12 385 randomly sampled Australian adults over 2007, 2009, and 2013 in the Household, Income, and Labour Dynamics in Australia Survey. We adjusted effects on incident changes in happiness and life satisfaction for people's changing incomes and personal circumstances. RESULTS Increased fruit and vegetable consumption was predictive of increased happiness, life satisfaction, and well-being. They were up to 0.24 life-satisfaction points (for an increase of 8 portions a day), which is equal in size to the psychological gain of moving from unemployment to employment. Improvements occurred within 24 months. CONCLUSIONS People's motivation to eat healthy food is weakened by the fact that physical health benefits accrue decades later, but well-being improvements from increased consumption of fruit and vegetables are closer to immediate. POLICY IMPLICATIONS Citizens could be shown evidence that "happiness" gains from healthy eating can occur quickly and many years before enhanced physical health.
Extrapolating fiber crossings from DTI data : can we gain the same information as HARDI?

High angular resolution diffusion imaging (HARDI) has proven to better characterize complex intra-voxel structures compared to its predecessor diffusion tensor imaging (DTI). However, the benefits from the modest acquisition costs and significantly higher signal-to-noise ratios (SNRs) of DTI make it more attractive for use in clinical research. In this work we use contextual information derived from DTI data, to obtain similar crossing information as from HARDI data. We conduct a synthetic phantom study under different angles of crossing and different SNRs. We compare the extrapolated crossings from contextual information with HARDI data. We qualitatively corroborate our findings from the phantom study to real human data. We show that with extrapolation of the contextual information, the obtained crossings are similar to the ones from the HARDI data, and the robustness to noise is significantly better.
Deuterium abundance in the most metal-poor damped Lyman alpha system: converging on Ωb,0h2

The most metal-poor damped Lyα system known to date, at zabs= 2.61843 in the spectrum of the QSO Q0913+072, with an oxygen abundance of only ∼1/250 of the solar value, shows six well-resolved DI Lyman series transitions in high-quality echelle spectra recently obtained with the European Southern Observatory (ESO) VLT. We deduce a value of the deuterium abundance log (D/H) =−4.56 ± 0.04 which is in good agreement with four out of the six most reliable previous determinations of this ratio in QSO absorbers. We find plausible reasons why in the other two cases the 1σ errors may have been underestimated by about a factor of two. The addition of this latest data point does not significantly change the mean value of the primordial abundance of deuterium, suggesting that we are now converging to a reliable measure of this quantity. We conclude that〈log (D/H)p〉=−4.55 ± 0.03 and Ωb,0h2(BBN) = 0.0213 ± 0.0010 (68 per cent confidence limits). Including the latter as a prior in the analysis of the Wilkinson Microwave Anisotropy Probe (WMAP) five-year data leads to a revised best-fitting value of the power-law index of primordial fluctuations ns= 0.956 ± 0.013 (1σ) and ns < 0.990 with 99 per cent confidence. Considering together the constraints provided by WMAP 5, (D/H)p, baryon oscillations in the galaxy distribution, and distances to Type Ia supernovae, we arrive at the current best estimates Ωb,0h2= 0.0224 ± 0.0005 and ns= 0.959 ± 0.013.
How Transformational Leadership Influences Employee Voice Behavior: The Roles of Psychological Capital and Organizational Identification

We proposed a model with which we jointly tested psychological capital (PsyCap) as the key psychological mechanism through which transformational leadership (TL) affects employee voice behavior (VB), and examined the moderating effect of employees’ organizational identification (OI) on the PsyCap–VB relationship. Data were collected from employees in companies located in southern China and a small group of Master of Business Administration students who were also in paid employment ( N = 237). Results showed that PsyCap fully mediated the TL–VB relationship, and that the effect of PsyCap on VB would be stronger when OI was high than when it was low. Both theoretical and practical implications of the study are discussed, as well as limitations and future directions for research.
Deep Residual Learning for Compressed Sensing CT Reconstruction via Persistent Homology Analysis

Recently, compressed sensing (CS) computed tomography (CT) using sparse projection views has been extensively investigated to reduce the potential risk of radiation to patient. However, due to the insufficient number of projection views, an analytic reconstruction approach results in severe streaking artifacts and CS-based iterative approach is computationally very expensive. To address this issue, here we propose a novel deep residual learning approach for sparse view CT reconstruction. Specifically, based on a novel persistent homology analysis showing that the manifold of streaking artifacts is topologically simpler than original ones, a deep residual learning architecture that estimates the streaking artifacts is developed. Once a streaking artifact image is estimated, an artifact-free image can be obtained by subtracting the streaking artifacts from the input image. Using extensive experiments with real patient data set, we confirm that the proposed residual learning provides significantly better image reconstruction performance with several orders of magnitude faster computational speed.
Explaining socioemotional selectivity theory with temporal and social discounting

Research on Socioemotional Selectivity Theory showed that the perception of remaining time until endings (e.g. death, graduation, emigration) affects motivations, emotion regulation, and cognitive processing. Specifically, as future time perspective shrinks, the motivation for emotion-related goals increases, as compared to knowledge-related goals. Another area of research on how temporal distance influences the subjective value of outcomes revealed that the present perceived value of a future outcome decreases as its temporal delay increases, which follows a hyperbolic curve. Integrating the two lines of research, the present study proposed that the motivational shifts related to change in future time perspective might be associated with a cost-benefit analysis of immediate and delayed outcomes. 74 Hong Kong residents participated in the current study. They completed a computerized administration of questionnaires and experimental conditions. They made series of choices between a shorter-sooner and a longer-later social interactions, with both emotion-related and knowledge-related social partners. Results indicated that social interactions with emotion-related social partners were discounted steeper than that with knowledge-related social partners. In addition, perceived social distance mediated the effect of types of social partners on delay discounting rates. Findings also showed that emotion-related social partners were valued more than knowledge-related social partners when both were delivered immediately (i.e. higher initial value). Taken together, these results suggest that future emotion-related outcomes might be valued more (compared to knowledge-related outcomes) in a limited future time perspective, and valued less as future time perspective expands. The current findings might help provide a novel perspective in explaining the association between ___________________________________________________________________________________________________________________________________ This document is downloaded from Outstanding Academic Papers by Students (OAPS), Run Run Shaw Library, City University of Hong Kong SOCIOEMOTIONAL SELECTIVITY THEORY AND DISCOUNTING iii the perception of time horizon and motivation, and the related changes in emotion regulation and cognitive processing. ___________________________________________________________________________________________________________________________________ This document is downloaded from Outstanding Academic Papers by Students (OAPS), Run Run Shaw Library, City University of Hong Kong SOCIOEMOTIONAL SELECTIVITY THEORY AND DISCOUNTING iv
