The psychological implications of the closing of a mine for workers and their families

This article arose from a project which was launched on behalf of the Labour Union Solidarity after the interim liquidation and immediate closing of the Durban Roodepoort Deep (DRD) Gold Mine at Stilfontein. This mining community was also traumatized by an earthquake shortly before the closing of the mine. The process commenced on 27 April 2005, when a contract was drawn up with Solidarity’s Helping Hand Fund to do a psychosocial situation analysis among the community. Based on the results of the psychosocial situation analysis, a project plan was submitted to Solidarity, after which a formal agreement was reached between the two parties and a meeting with the representatives of the labour union was held. Following this, the plan of action was proposed, the facilitators trained and the programme implemented. The data of the psychosocial situation analysis, the contents and course of the group sessions as well as the results that ensued from the questionnaire that was filled in by the women during the women’s day as well as certain strengths present in the community are discussed. This is followed by an integrated discussion of the investigation. A number of recommendations are also made for the future.
Generation of All-Paths Unit Test with Function Calls

Structural testing is usually restricted to unit tests and based on some clear definition of source code coverage. In particular, the all-paths criterion, which requires at least one test-case per feasible path of the function under test, is recognised as offering a high level of software reliability. This paper deals with the difficulties of using structural unit testing to test functions which call other functions. To limit the resulting combinatorial explosion in the number of paths, we choose to abstract the called functions by their specification. We incorporate the functional information on the called functions within the structural information on the function under test, given as a control flow graph (CFG). This representation combining functional and structural descriptions may be viewed as an extension of the classic CFG and allows us to characterise test selection criteria ensuring the coverage of the source code of the function under test. Two new criteria will be proposed. The first criterion corresponds to the coverage of all the paths of this new representation, including all the paths arising from the functional description of the called functions. The second criterion covers all the feasible paths of the function under test only. We describe how we automate test-data generation with respect to such grey-box (combinations of black- box and white-box) test selection strategies, and we apply the resulting extension of our PathCrawler tool to examples coded in the C language.
Suicide beliefs and behaviour among young Muslims and Hindus in the UK

It has been suggested that Hindu tradition is relatively tolerant of suicide, while Islamic tradition has consistently regarded suicide as a very grave sin. This study sought to examine the possible impact of religious-cultural tradition by examining suicide-related beliefs and reported behaviour in non-clinical samples of young Hindus ( n = 40) and Muslims ( n = 60) living in the UK. Participants completed a short demographic questionnaire, the Reasons for Living Inventory, and measures of suicide thoughts, plans and behaviour. The Hindus endorsed moral, total and (marginally) survival-and-coping reasons for living less strongly than did the Muslims. Women endorsed family-related, fear of suicide and (marginally) total reasons for living less strongly than did men. There were no noteworthy between-group differences with respect to suicide thoughts, plans or behaviour. Causal inferences are not possible, but the results are consistent with the suggestions that scriptural differences between Hinduism and Islam in attitudes to suicide may be responsible for some of the differences detected in this study.
A Framework for QoS-aware Traffic Classification Using Semi-supervised Machine Learning in SDNs

In this paper, a QoS-aware traffic classification framework for software defined networks is proposed. Instead of identifying specific applications in most of the previous work of traffic classification, our approach classifies the network traffic into different classes according to the QoS requirements, which provide the crucial information to enable the fine-grained and QoS-aware traffic engineering. The proposed framework is fully located in the network controller so that the real-time, adaptive, and accurate traffic classification can be realized by exploiting the superior computation capacity, the global visibility, and the inherent programmability of the network controller. More specifically, the proposed framework jointly exploits deep packet inspection (DPI) and semi-supervised machine learning so that accurate traffic classification can be realized, while requiring minimal communications between the network controller and the SDN switches. Based on the real Internet data set, the simulation results show the proposed classification framework can provide good performance in terms of classification accuracy and communication costs.
Experimental set-up for antenna characterization in waterpipes

Wireless Sensor Networks have been recently proposed for applications in a large variety of systems. Among all, the possibility to insert a terminal node inside a dissipative liquid medium has attracted attention by few authors. For this reason, the paper presents the design and construction of a test bench for the experimental characterization of antennas inside liquids. The design has involved the classification of a large variety of pipelines, among which three different samples have been selected. The pipeline has consequently been configured in order to host fixed or mobile antennas, which can be wired towards the external part of the conduit, to facilitate their connection to a network analyzer. The speed and pressure of the liquid, as well as the speed of the antenna, can be controlled remotely. Finally, in case of metallic pipelines, a procedure has been introduced to test the attenuation along the longitudinal direction of the conduit.
Limited Polymorphism of the Kelch Propeller Domain in Plasmodium malariae and P. ovale Isolates from Thailand

ABSTRACT Artemisinin resistance in Plasmodium falciparum, the agent of severe malaria, is currently a major obstacle to malaria control in Southeast Asia. A gene named “kelch13” has been associated with artemisinin resistance in P. falciparum. The orthologue of the kelch gene in P. vivax was identified and a small number of mutations were found in previous studies. The kelch orthologues in the other two human malaria parasites, P. malariae and P. ovale, have not yet been studied. Therefore, in this study, the orthologous kelch genes of P. malariae, P. ovale wallikeri, and P. ovale curtisi were isolated and analyzed for the first time. The homologies of the kelch genes of P. malariae and P. ovale were 84.8% and 82.7%, respectively, compared to the gene in P. falciparum. kelch polymorphisms were studied in 13 P. malariae and 5 P. ovale isolates from Thailand. There were 2 nonsynonymous mutations found in these samples. One mutation was P533L, which was found in 1 of 13 P. malariae isolates, and the other was K137R, found in 1 isolate of P. ovale wallikeri (n = 4). This result needs to be considered in the context of widespread artemisinin used within the region; their functional consequences for artemisinin sensitivity in P. malariae and P. ovale will need to be elucidated.
To assist or not to assist? A study of teachers’ views of the roles of learning support assistants in the provision of inclusive physical education in England

This paper examines teachers’ perceptions of their working relationships with learning support assistants (LSAs) when seeking to incorporate young disabled people and pupils with special educational needs (SEN) within mainstream physical education (PE), an area that has been a largely neglected aspect of research in inclusive education. The findings indicate that teachers spoke positively of these relationships when LSAs were perceived as making a positive contribution to the development of pupils’ learning and when they supported teachers as they did in other school subjects. Conversely, when LSAs and other support staff failed to provide teachers with information that was related to pupils’ needs in PE, and when LSAs did not possess the required skills, knowledge and expertise of the subject, teachers were rather critical of their relationships with them. In this regard, LSAs were seen as placing a particularly significant constraint on teachers’ ability to meet the needs of pupils in PE lessons. It is concluded that teachers’ perceptions of the constraints they experience from working with LSAs to help support pupils, and the extent and quality of support they receive, cannot be understood adequately unless they are located within the context of the relational constraints experienced by teachers.
Kainic acid‐induced status epilepticus alters GABAA receptor subunit mRNA and protein expression in the developing rat hippocampus

Kainic acid‐induced status epilepticus leads to structural and functional changes in inhibitory GABAA receptors in the adult rat hippocampus, but whether similar changes occur in the developing rat is not known. We have used in situ hybridization to study status epilepticus‐induced changes in the GABAAα1–α5, β1–β3, γ1 and γ2 subunit mRNA expression in the hippocampus of 9‐day‐old rats during 1 week after the treatment. Immunocytochemistry was applied to detect the α1, α2 and β3 subunit proteins in the control and treated rats. In the saline‐injected control rats, the α1 and α4 subunit mRNA expression significantly increased between the postnatal days 9–16, whereas those of α2, β3 and γ2 subunits decreased. The normal developmental changes in the expression of α1, α2, β3 and γ2 subunit mRNAs were altered after the treatment. The immunostainings with antibodies to α1, α2 and β3 subunits confirmed the in situ hybridization findings. No neuronal death was detected in any hippocampal subregion in the treated rats. Our results show that status epilepticus disturbs the normal developmental expression pattern of GABAA receptor subunit in the rat hippocampus during the sensitive postnatal period of brain development. These perturbations could result in altered functional and pharmacological properties of GABAA receptors.
A low-power, size efficient 1 - 7 GHz CMOS UWB Low Noise Amplifier

Ultra Wideband (UWB) system is a new wireless technology capable of transmitting data over the wide spectrum of frequency band with very low power and high data rates. For a wideband application such as UWB system, wideband input matching and sufficient gain over the entire bandwidth are important. One of the most critical devices in the receiver of UWB system is a low noise amplifier (LNA). It must satisfy the low noise figure (NF), sufficient gain with flatness and low power consumption over the wide frequency range [1]. To satisfy these requirements, CMOS technology is one of key technologies not only to provide the high performance but also to reduce the manufacturing cost. Previous suggested UWB LNAs using CMOS process [2 4] consume much power and require many inductors to achieve high performance. In this paper, we propose a low power and size efficient 1 – 7 GHz UWB LNA using the current reuse technique and it is implemented by TSMC 0.18 μm RF CMOS process. The proposed LNA scheme can also be applied to WCDMA (1920 2170 MHz) and WLAN (2400 2483 MHz / 5150 5350 MHz) systems.
Multi-static MIMO-SAR three dimensional deformation measurement system

Herein is proposed a novel high-steep rock slope landslide monitoring system based on the configuration of multi-static multiple-input multiple-output synthetic aperture radar (MIMO-SAR). In this system, three spastically distributed radars are employed. Each is a Ku-band MIMO-SAR, transmitting mutually orthogonal waveforms and sensing the slope movement from different view angles. The three radars can then achieve the deform measurements in the three line of sight (LOS) directions. After an effective fusion of these measurements, the deform vector, with direction and amount, can be resolved. This vector is particularly important for risk warning as well as for understanding the motion mechanism of landslide. Moreover, the data acquisition period can be largely reduced, since the use of MIMO radar allows a simultaneous sampling of the scene echo. The time decorrelation is therefore very small, and hence high measurement accuracy can be expected. It can be proved that, using this system, the three-dimensional accuracy can reach 0.1 ~ 1 mm. Simulations and experimental datasets are used to validate this proposal.
Educational Attainment and Health: Evidence from a Sample of Older Adults

This paper provides evidence of an education-health relationship among older adults, even after controlling for individual and family background characteristics. It also explores to what extent this relationship represents an independent effect of education on health. An identification strategy using the quarter of birth and a set of parental and sibling characteristics as instrumental variables for education is used to purge estimates of biases resulting from error components correlated with education. The results suggest that the previously observed correlation between educational attainment and adult health has a causal component.
Travel motivations and satisfaction: a case of national cultural festival-goers in Korea.

Information about motivation related to travel behavior allows marketers to better understand and predict individuals� decision making. This study identifi ed underlying motivational factors of national cultural festival-goers in Korea and classifi ed distinct travel groups attending the festival. Factor analysis determined eight reliable motivational factors and cluster analysis suggested three heterogeneous travel groups. To validate the travel groups, analysis of variance (ANOVA) and discriminant analysis were performed, followed by the chi-square statistic. The fi ndings support that signifi cant differences exist in the motivational factors, overall satisfaction levels, annual income, and duration of the visit across the three travel groups. Practical implications are discussed for festival marketers to promote cultural festival visits.
Switched-Beam Slot Antenna over Electromagnetic Band-Gap Reflector

This paper presents the switched-beam slot antenna over the electromagnetic band-gap (EBG) reflector. This antenna is composed of two slot elements fed with a phase difference and the EBG reflector, which is used in order to realize a low profile structure. The radiation characteristics of this antenna are calculated using the FDTD method. Calculations show that the height of the antenna using the EBG reflector is 60 % lower than that of the antenna using a perfect electric conductor (PEC) reflector. The radiation characteristics at the center of the operating frequency band in the EBG reflector are equivalent to that in the PEC reflector. It is shown that the tilt angle of the main beam in the elevation plane varies with the operating frequency, and the variation in the case of the EBG reflector is caused by its frequency-dependent reflection phase. Moreover, the radiation pattern of the fabricated antenna is measured. The results demonstrate that the low profile design can be achieved by using the EBG reflector, and reveal the influence of the EBG reflector on the antenna efficiency.
Teaching distributed software development with the project method

Lab courses are an integral part of higher education in engineering sciences. In this paper, we report about a blended learning approach for such courses in computer science education. We show how the project method for co-located learning can be translated into a blended CSCL setting for a lab course on distributed software development, and how the resulting learning scenario can be supported with the collaborative virtual learning environment CURE. Experiences from the application of the educational approach in two courses indicate benefits but also highlight the need for further technical support.
A Markov-based Recommendation Model for Exploring the Transfer of Learning on the Web

The ability to apply existing knowledge in new situations and settings is clearly a vital skill that all students need to develop. Nowhere is this truer than in the rapidly developing world of Web-based learning, which is characterized by non-sequential courses and the absence of an effective cross-subject guidance system. As a result, questions have arisen about how to best explore and stimulate the transfer of learning from one subject to another in electronically mediated courses of study. In this study, we argue that online learners would benefit from guidance along applicable group-learning paths. This paper proposes use of the learning sequence recommendation system (LSRS) to help learners achieve effective Web-based learning transfer using recommendations based on group-learning paths. We begin with a Markov chain model, which is a probability transition model, to accumulate transition probabilities among learning objects in a course of study. We further employ an entropy-based approach to assist this model in discovering one or more recommended learning paths through the course material. Statistical results showed that the proposed approach can provide students with dependable paths leading to higher achievement levels, both in terms of knowledge acquisition and integration, than those typically attained in more traditional learning environments. Our study also identified benefits for teachers, providing them with ideas and tools needed to design better online courses. Thus, our study points the way to a Web-based learning transfer model that enables teachers to refine the quality of their instruction and equips students with the tools to enhance the breadth and depth of their education.

The Contribution of Autonomic Imbalance to the Development of Metabolic Syndrome

Objectives Obesity, diabetes, and heart disease—the most costly epidemics of our time—share a common but rarely treated mechanism: autonomic imbalance. We examined the contribution of autonomic imbalance, relative to selected demographic and biobehavioral risk factors, to the development of metabolic syndrome in a community sample for 12 years. Methods We identified offspring cohort participants from the Framingham Heart Study who did not have metabolic syndrome at Examination 3 (1983–1987, baseline for this analysis) and whose metabolic syndrome status was assessed at the 4-, 8-, and 12-year follow-ups. We created logistic regression models, using baseline resting heart rate (RHR) and heart rate variability (HRV), to predict the odds of developing metabolic syndrome within 12 years, adjusting for age, sex, depressive symptoms, and smoking. HRV indices (standard deviation of the beat-to-beat interval [SDNN] and root mean square of the standard deviation) were calculated from 2-hour Holter monitor data. Results Our sample consisted of 1143 participants (mean [SD] age = 46.6 (9.9) years, 57% female). One standard deviation of a decrease in SDNN increased the odds of developing metabolic syndrome within 12 years by 43% (95% confidence interval = 1.302–1.572, p < .001). Without HRV in the model, each increase in RHR of 10 beats/min increased the odds of developing metabolic syndrome by 24% (95% confidence interval = 1.094–1.426, p < .001). Conclusions In this community sample, low HRV by both measures (SDNN and root mean square of the standard deviation), high RHR, increased age, cigarette smoking, and being male significantly increased the odds of developing metabolic syndrome within 12 years of baseline.
Updated opacities from the Opacity Project

Using the code autostructure, extensive calculations of inner-shell atomic data have been made for the chemical elements He, C, N, O, Ne, Na, Mg, Al, Si, S, Ar, Ca, Cr, Mn, Fe and Ni. The results are used to obtain updated opacities from the Opacity Project (OP). A number of other improvements on earlier work have also been included. Rosseland-mean opacities from the OP are compared with those from OPAL. Differences of 5-10 per cent occur. The OP gives the 'Z-bump', at log(T) 5.2, to be shifted to slightly higher temperatures. The opacities from the OP, as functions of temperature and density, are smoother than those from OPAL. The accuracy of the integrations used to obtain mean opacities can depend on the frequency mesh used. Tests involving variation of the numbers of frequency points show that for typical chemical mixtures the OP integrations are numerically correct to within 0.1 per cent. The accuracy of the interpolations used to obtain mean opacities for any required values of temperature and density depends on the temperature-density meshes used. Extensive tests show that, for all cases of practical interest, the OP interpolations give results correct to better than 1 per cent. Prior to a number of recent investigations which have indicated a need for downward revisions in the solar abundances of oxygen and other elements, there was good agreement between properties of the Sun deduced from helioseismology and from stellar evolution models calculated using OPAL opacities. The revisions destroy that agreement. In a recent paper, Bahcall et al. argue that the agreement would be restored if opacities for the regions of the Sun with 2 × 106T 5 × 106 K (0.7-0.4 R) were larger than those given by OPAL by about 10 per cent. In the region concerned, the present results from the OP do not differ from those of OPAL by more than 2.5 per cent.
RESEARCH: Religiosity, Authoritarianism, and Homophobia: A Multidimensional Approach

Research on religiosity and homophobic prejudice has typically employed unidimensional measures of antigay prejudice that measure homophobia as a single collective set of attitudes. To better understand the religiosity-homophobia relationship, the study reported here examined the relations of authoritarianism and several measures of religiosity to a multidimensional measure of homophobia that assess respondents' social contact apprehension, morality beliefs, civil rights attitudes, and stereotypic beliefs regarding gay men and lesbians. A canonical correlation analysis on 443 heterosexual undergraduates indicated that the religiosity-homophobia relationship was influenced by the component of homophobia assessed. The results reported here suggest that the relationship between religiosity and homophobia may be more complex than previous research with unidimensional measures indicates.
