Followers' Personality and Leadership

The study presented in this article investigates how the personality of subordinates is related to leadership, an area largely neglected in prior research. Subordinates (n = 289) rated their immediate superior on transformational, transactional, and passive-avoidant leadership measured by the Multifactor Leadership Questionnaire (MLQ) and completed the NEO-FFI, with the five traits neuroticism, extraversion, openness, agreeableness, and conscientiousness. The results revealed that subordinates' personality (n = 289) was only moderately associated with leadership ratings. Links were found between ratings of transformational leadership and subordinates' level of neuroticism and agreeableness. Furthermore, ratings of passive-avoidant leadership were associated with subordinates' level of agreeableness and openness.

The Performance of Group Lasso for Linear Regression of Grouped Variables

The lasso [19] and group lasso [23] are popular algorithms in the signal processing and statistics communities. In signal processing, these algorithms allow for efficient sparse approximations of arbitrary signals in overcomplete dictionaries. In statistics, they facilitate efficient variable selection and reliable regression under the linear model assumption. In both cases, there is now ample empirical evidence to suggest that an appropriately regularized group lasso can outperform the lasso whenever there is a natural grouping of the dictionary elements/regression variables in terms of their contributions to the observations [1, 23]. Our goal in this technical report is to analytically characterize the regression performance of the group lasso algorithm using `1/`2 regularization for the case in which one can have far more regression variables than observations. Analytical characterization of group lasso in this “underdetermined” setting has received some attention lately in the statistics literature [1, 14–17]. However, prior analytical work on the performance of group lasso either studies an asymptotic regime [1, 15–17], focuses on random design matrices [1, 16], and/or relies on metrics that are computationally expensive to evaluate [14, 15, 17]. Recently, Candes and Plan [4] successfully circumvented somewhat similar shortcomings
The Impact of Adaptive Learning Material based on Learning Styles in E-learning Portal using Empirical Study

The main objective of this paper is to determine whether there is significant improvement in the performance of engineering students when teaching material is provided on e-learning portal which matches the learning styles of individual student. The quantitative method of study was used, specifically the pretest-posttest method on control and experimental group. The population selected is second year engineering student class for programming language subject according to non-probability sampling method. The two groups of samples are selected randomly from one class unit. The paired t-test was applied to analyze the data. The result indicated a statistically significant increase in pretest and posttest results of experimental group. Experimental result indicated that matching learning styles with the provided teaching material improves the performance of students significantly.
A comparison of mental state examination documentation by junior clinicians in electronic health records before and after the introduction of a semi-structured assessment template (OPCRIT+)

Objectives: The mental state examination (MSE) provides crucial information for healthcare professionals in the assessment and treatment of psychiatric patients as well as potentially providing valuable data for mental health researchers accessing electronic health records (EHRs). We wished to establish if improvements could be achieved in the documenting of MSEs by junior doctors within a large United Kingdom mental health trust following the introduction of an EHR based semi-structured MSE assessment template (OPCRIT+). Methods: First, three consultant psychiatrists using a modiﬁed version of the Physician Documentation Quality Instrument-9 (PDQI-9) blindly rated ﬁfty MSEs written using OPCRIT+ and ﬁfty normal MSEs written with no template. Second, we conducted an audit to com-pare the frequency with which individual components of the MSE were documented in the normal MSEs compared with the OPCRIT + MSEs. Results: PDQI-9 ratings indicated that the OPCRIT + MSEs were more ‘Thorough’, ‘Organized’, ‘Useful’ and ‘Comprehensible’ as well as being of an overall higher quality than the normal MSEs. The audit identiﬁed that the normal MSEs contained fewer mentions of the individual components of ‘Thought content’, ‘Anxiety’ and ‘Cognition & Insight’. Conclusions: These results indicate that a semi-structured assessment template signiﬁcantly improves the quality of MSE recording by junior doctors within EHRs. Future work should focus on whether such improvements translate into better patient outcomes and have the ability to improve the quality of information available on EHRs to researchers.
OBSERVATIONS ON THE RESULTS OF PREGNANCIES IN WOMEN RESIDENT IN BELFAST

This first paper of a series of three presents data concerning the outcomes of all pregnancies terminating in Belfast in 1957, and describes the modes of identification of such pregnancies. In it are discussed briefly the malformations present at birth in foetuses born alive or dead after the beginning of the 28th week of pregnancy as measured conventionally from the first day of the preceding menstrual period.
Deep Search with Attribute-aware Deep Network

In this demo, we present Deep Search, an attribute-aware fashion-related retrieval system, based on the convolutional neural network by taking clothes as a concrete example. In this system, the visual appearance and semantic attributes of products can be seamlessly integrated into our model in a "dividing and combining" manner. Rather than modelling one attribute per classifier, we design a holistic tree-structure network for exploiting multiple attributes simultaneously, with each branch of network corresponding to one attribute. Therefore, the high-level feature from the conjunction layer of the network can comprehensively preserve both the visual and semantic information of products. The promising retrieval results indicate the great potential of neural feature for attribute-aware retrieval task. The supplementary slides can be found in http://goo.gl/zpobN6.
OLA-RAW: Scalable Exploration over Raw Data

In-situ processing has been proposed as a novel data exploration solution in many domains generating massive amounts of raw data, e.g., astronomy, since it provides immediate SQL querying over raw files. The performance of in-situ processing across a query workload is, however, limited by the speed of full scan, tokenizing, and parsing of the entire data. Online aggregation (OLA) has been introduced as an efficient method for data exploration that identifies uninteresting patterns faster by continuously estimating the result of a computation during the actual processing---the computation can be stopped as early as the estimate is accurate enough to be deemed uninteresting. However, existing OLA solutions have a high upfront cost of randomly shuffling and/or sampling the data. In this paper, we present OLA-RAW, a bi-level sampling scheme for parallel online aggregation over raw data. Sampling in OLA-RAW is query-driven and performed exclusively in-situ during the runtime query execution, without data reorganization. This is realized by a novel resource-aware bi-level sampling algorithm that processes data in random chunks concurrently and determines adaptively the number of sampled tuples inside a chunk. In order to avoid the cost of repetitive conversion from raw data, OLA-RAW builds and maintains a memory-resident bi-level sample synopsis incrementally. We implement OLA-RAW inside a modern in-situ data processing system and evaluate its performance across several real and synthetic datasets and file formats. Our results show that OLA-RAW chooses the sampling plan that minimizes the execution time and guarantees the required accuracy for each query in a given workload. The end result is a focused data exploration process that avoids unnecessary work and discards uninteresting data.
Teacher attitudes toward mainstreaming: a cross‐cultural study in six nations

ABSTRACT Attitudes of teachers toward the educational mainstreaming of special needs students in six nations ‐ the United States, Germany, Israel, Ghana, Taiwan, and the Philippines ‐ were compared. Also investigated were teacher background variables associated with attitudes toward integration. Findings revealed that the most supportive views were expressed by teachers in the United States followed by educators in Germany. Attitudes of teachers in the other nations represented mainly a neutral disposition toward mainstreaming. The lowest attitude scores were obtained for Israeli non‐kibbutz educators. Several variables were associated with attitudes: training in special education, grade level, age, teaching experience, and experience with individuals who are disabled. The role that teacher preparation programs and effective mainstreaming practices have in the development of teacher support for integration are discussed.
The Impact of Childcare Responsibility and Self-Efficacy on the Psychological Health of Professional Working Mothers

This study examined how childcare responsibility and self-efficacy to manage multiple role demands related to the psychological well-being and distress of 42 full-time professional women one month after they returned to their jobs after the birth of their first child. The results showed that greater childcare responsibility is associated with lower well-being and greater psychological distress. As predicted, perceived self-efficacy to cope with demands of occupational and familial roles appeared to mediate this relationship. A woman's belief in her capability to enlist the help of her spouse for childcare was the most consistent predictor of both well-being and distress.
Teaching People to Fish? Building the Evaluation Capability of Public Sector Organizations

In response to an increasing demand for public sector accountability, many government agencies have sought to develop their internal evaluation capabilities. Often these efforts have focused on increasing the capacity to supply credible evaluations, yet addressing demand is just as important. This article focuses on a government agency and tracks its five-year journey towards developing such a capability. It documents contextual matters, drivers for change, the actions taken by the agency, and its response to emergent challenges during four phases. Based on feedback from project staff and managers and those involved in the capability development project, it offers seven recommendations. These are: start small and grow evaluation; address both supply and demand; work top-down and bottom-up simultaneously; use a theory of change behaviour; develop a common evaluation framework, including a generic programme theory; build knowledge of what works within the agency's context; and systematically and visibly evaluate each stage.
In vitro activity of 1,3-bisaryloxypropanamines against Trypanosoma cruzi-infected L929 cultures

We describe herein the antitrypanosomal activity of 20 novel 1,3-bis(aryloxy)propan-2-amine derivatives. Compounds 2, 4, 6, 12, 15, 16 and 19 were significantly active against amastigote and trypomastigote forms, with half maximal inhibitory concentrationvalues in the range of 6-18 µM. In the cytotoxicity tests against L929 cells, only compound 4 presented selectivity index value above 10, indicating low toxicity.
Mortality among PVC-fabricating employees.

The results of a cross-sectional mortality study of 3847 deaths occurring among current and former (white) employees of 17 PVC fabricators during 1964-1973 are presented. Sex-race-cause-specific proportionate mortality ratios (PMR's) were computed by using two separate standards: one, the U.S. mortality in 1968; the second, U.S. mortality for the individual years 1964-1973. In addition, a case-control analysis, based upon 44 breast cancer deaths among white female employees, is presented. PMR's are significantly different from unity for all cancers, and for cancers of the digestive system among both white males and white females. Although observed deaths significantly exceeded expectations for cancer of the breast, a subsequent case-control analysis reveals no statistically significant relative risks for breast cancer.
Multi-view surface reconstruction using polarization

A new technique for surface reconstruction is developed that uses polarization information from two views. One common problem arising from many multiple view techniques is that of finding correspondences between pixels on each image. In the new method, these correspondences are found by exploiting the spontaneous polarization of light caused by reflection to recover surface normals. These normals are then used to recover surface height. The similarity between reconstructed surface regions determines whether or not a pair of points correspond to each other. The technique is thus able to overcome the convex/concave ambiguity found in many single view techniques. Because the technique relies on smooth surface regions to detect correspondences, rather than feature detection, it is applicable to objects normally inaccessible to stereo vision. Also due to this fact, it is possible to remove noise without causing oversmoothing problems.
The Effect of Image Features on Judgments of Homophily, Credibility, and Intention to Use as Avatars in Future Interactions

Avatar characteristics influence the perception of the people they represent in a process that is remarkably similar to the way physical bodies influence person perception offline. This is consistent with the Social Responses to Computer Technologies model, which argues that people respond similarly to computers and people as long as sources are perceived to be intelligent. Similarly, Information Processing Theory suggests that the viewers apply the same evaluation sequences to nearly all sources and that more processing resources are allocated to perceiving an entity with social potential. To address the extent to which static avatars are perceived to be intelligent and human like, or have social potential, participants (N = 261) each evaluated a random set of 10 images as potential avatars. The avatars varied with respect to level of computer manipulation, visible indicators of masculinity, and anthropomorphism (having human characteristics). Results confirm that even static avatars are anthropomorphized and that visual characteristics influence perceptions of the avatars. Level of computer manipulation, masculinity, and anthropomorphism all influence perceived levels of realism, competence, and the sense of homophily with the avatar. The implications of these results for theory, future research, and for users and designers of communication systems are discussed.
Correlates of sexual risk-taking behaviour among HIV seropositive gay men in concordant primary partner relationships

This study sought to understand how person, perceived health risks, psychosocial, and mental health factors relate to unprotected anal intercourse (UAI) among 91 HIV seropositive (HIV + ) gay men in concordant primary partner relationships. The data was drawn from a larger sample of 464 HIV + men-who-have-sex-with-men (MSM) from mainstream gay venues, AIDS service organizations, and public sex environments in New York City and San Francisco. The findings from this study suggest that UAI is a common behaviour among HIV + gay men in seroconcordant couples, which may compromise their health due to the possibility of HIV reinfection and the transmission of other sexually transmitted diseases. Results from our analyses indicated that lower perceived risk of HIV reinfection, lower behavioural intentions for condom use, and higher CD4 counts were predictive of HIV + gay men engaging in UAI with their HIV + primary partner. In situations where there is discordance in HIV strain type or in dyads where monogamy is not maintained, the practice of UAI may present health risks for the men in HIV + seroconcordant relationships.
[Relationship between pain symptoms and clinico-pathological features of pelvic endometriosis].

OBJECTIVE To study the relationship between pain symptoms and the clinico-pathological features of pelvic endometriosis (EM). METHODS One hundred thirty patients with laparoscopic diagnosis of EM were studied retrospectively and the relationship between pain symptoms including dysmenorrhea, chronic pelvic pain (CPP), dyspareunia and dyschezia and the anatomical features of pelvic endometriosis were evaluated. RESULTS One hundred (76.9%) patients with pain symptoms and 30 (23.1%) without were included in this study. The number of patients with mild, moderate and severe dysmenorrhoea was 27 (20.8%), 41 (31.5%), and 32 (24.6%), respectively. Patients with dyspareunia, CPP and dyschezia were 46 (35.4%), 45 (34.6%) and 67 (51.5%), respectively. Compared with patients without dysmenorrhea, the proportion of deep utero-sacral nodules (45.0% vs 13.3%, P=0.00), recto-vaginal nodules (16.0% vs 0, P=0.01), complete obliteration of cul-de sac (41.0% vs 10.0%, P=0.00), and lesions of DIE (51.0% vs 16.7%, P=0.00) was significantly increased in patients with dysmenorrhea. The severity of dysmenorrhea was positively correlated with nodules in uterosacral ligaments (P=0.005, r=0.302), and invasive depth of uterosacral ligaments (P=0.016, OR=5.085). Among patients with endometrioma, significantly more moderate to severe adhesions were found in patients with dysmenorrhea, compared with those patients without dysmenorrhea (29.1% vs 8.3%, P=0.029). Patients with CPP had more nodules in the utero-sacral ligaments (51.1% vs 30.6%, P=0.018) and DIE lesions (57.8% vs 35.3%, P=0.011), compared with those without. More nodules in the utero-sacral ligaments (46.3% vs 28.6%, P=0.028), recto-vaginal nodules (19.4% vs 4.8%, P=0.01), complete obliteration of cul-de sac (44.8% vs 22.2%, P=0.005) and DIE lesions (53.7% vs 31.7%, P=0.01) were found in patients with dyschezia, compared with those without. Nodules in the recto-vaginal pouch were an independent risk factor of dyspareunia. CONCLUSION Pain symptoms including dysmenorrhea, dyspareunia, chronic pelvic pain, and dyschezia are remarkably related to endometriotic nodules at the posterior part of the pelvis or those with deep invasions.

Results revealed two major themes: development of both professional and community perspectives. Outcomes of the study provide a framework for developing service-learning experiences across the curriculum.
Rate Control for Spatial Scalable Coding in SVC

In this paper, we present a new rate control scheme for spatial and coarse-grain-SNR (CGS) scalable coding in SVC. Firstly, a rate-distortion (R-D) model is provided for I/P/B frames according to mode analysis. Secondly, an efficient hierarchical bit allocation and two-pass refinement of quantization parameter (QP) are proposed. Thirdly, a standard deviation prediction between inter layers is presented. The experiments show that the proposed rate control scheme can achieve an average PSNR improvement of 0.3-0.7dB on average in terms of PSNR against the anchor scheme using hierarchical B frame coding with fixed QP. Meanwhile, the mismatch between target bit rate and real coded bit rate does not exceed 2%.

In developing this paper, we received helpful comments from This study develops a theoretical explanation for the existence of positive, as well as negative, experience spillovers across corporate development activities. We suggest that the similarity in two activities influences both the sign and magnitude of experience spillovers. The argument is used to understand how alliance experience influences the performance of acquisitions in the US commercial banking industry. The empirical evidence indicates that the spillover effect of alliance experience on acquisition performance is a function of the decisions made in the post-acquisition phase regarding the level of integration and the replacement of top management. We also find a U-shaped relationship between alliance experience and acquisition performance, suggesting the presence of negative spillovers across corporate development activities at low experience levels.
The quality of different types of child care at 10 and 18 months: a comparison between types and factors related to quality

The quality of care offered in four different types of non‐parental child care to 307 infants at 10 months old and 331 infants at 18 months old was compared and factors associated with higher quality were identified. Observed quality was lowest in nurseries at each age point, except that at 18 months they offered more learning activities. There were few differences in the observed quality of care by child‐minders, grandparents and nannies, although grandparents had somewhat lower safety and health scores and offered children fewer activities. Cost was largely unrelated to quality of care except in child‐minding, where higher cost was associated with higher quality. Observed ratios of children to adults had a significant impact on quality of nursery care; the more infants or toddlers each adult had to care for, the lower the quality of the care she gave them. Mothers' overall satisfaction with their child's care was positively associated with its quality for home‐based care but not for nursery settings.
