Coping and Coherence Among Parents With Disabled Children

Investigated coping, sense of coherence, and family climate among parents in 78 families with disabled children and 83 control families. The parents with disabled children showed significantly more avoidant coping, lower sense of coherence, and less emphasis on family members' interrelations and personal growth than did the control parents. Significant discrepancies between mothers and fathers were found in three areas: avoidant coping, sense of coherence, and personal growth. Parents' avoidant coping was predicted negatively by parental education and the sense-of-coherence construct, and positively by active coping and family system maintenance. The results focus attention onto the implications of personal and familial resources for raising a disabled child.
Mobile, flexible, and adaptable: female migrants in Hanoi's informal sector

Industrialisation and urban growth are constitutive aspects of Vietnam's new economy and are important driving forces behind increasing rural-to-urban migration. Growth in informal sector employment is a significant aspect of this development, which has provided for both male and female migrants, although they generally are engaged in different occupations. Based on a case study among porters at Hanoi's Long Bien Market, this paper examines rural-to-urban migrants' gendered migration practices. Two interrelated aspects of gendered migration practices are in focus: the role of migration networks and networking, and remittance practices. The paper is organised around why and how migrants have entered the informal labour market in Hanoi and how they make their livings there while also maintaining ties with their rural homes. In conclusion, we discuss how the migration networks and remittance practices of the female porters demonstrate a particular way of adapting to the migration process. Also, it is emphasised how women's flexible practices are facilitated by women's own village-based networks. It is suggested that ‘in-betweenness’, which stands for the simultaneous and overlapping presence of urban and rural spaces in migrants' lives, is an insightful way of comprehending the adaptation practices employed by female porters in Hanoi.

Examining conflict-handling approaches by Chinese top management teams in IT firms

Purpose – The purpose of this paper is to explore answers to two research questions: what types of conflicts do top management team (TMT) members in Chinese firms deal with; and what approaches do they take to handle them? Design/methodology/approach – Interview data were collected from 52 TMT members in 16 Chinese entrepreneurial high tech firms, and were transcribed, coded and analyzed according to Thomas's typology of conflict handling approaches.Findings – Results show that conflicts in those TMTs were mostly task‐related and integration/ collaboration was the most frequently used approach to handle conflicts, in contrast to the findings of previous studies with Chinese managers that reported avoidance to be most preferred. It was found that the most preferred approach used in the team also relates to the leadership style of the team leader.Research limitations/implications – Methodologically, the paper did not apply any quantitative approach to triangulate the findings for greater reliability nor did .
Prerequisite Skills That Support Learning through Video Modeling

The purpose of this study was to evaluate the relationship between tasks that require delayed discriminations such as delayed imitation and delayed matching to sample on acquisition of skills using video modeling. Twenty-nine participants with an ASD diagnosis were assessed on a battery of tasks including both immediate and delayed imitation and matching to sample tasks. All of the tasks were positively correlated with learning via video modeling. The most significant correlations were between delayed imitation of actions with objects and video modeling performance, as well as delayed matching accuracy and video modeling performance. Participants who performed well on subtest items that required performance after a delay showed mastery on the video modeling subtests. These findings suggest a simple method for educators to predict whether video modeling will be an effective teaching procedure for a specific child.
Who ‘Dominates’ Whom? Social Class, Conjugal Households and Political Identification

The existence of cross-class families, where the wife's occupation is taken to be superior to that of the husband, has been seen as a challenge to conventional ways of allocating class positions to partners in the conjugal household. Data from the Social Change and Economic Life Initiative survey conducted in 1986 are used to estimate the numerical importance of such families. Three approaches to the class allocation of men and women in conjugal households are outlined: individual, conventional and dominance. The predictive validity of these approaches is then assessed with the dependent variable drawn from the domain of political party identification. The outcomes of the exercise suggest that the conventional approach may require some slight finessing with respect to female respondents in cross-class families who are active full-time in the labour market, but in the main still gives acceptable results.
A follow-up of a home and school support project for children with emotional and behavioural difficulties

Abstract School exclusions remain at a high level in the UK. Exclusions are the result of the interaction of complex factors, and schools are not equipped to tackle disaffection and disruptive behaviour on their own. The article describes the evaluation of a multidisciplinary home and school support project in a city borough. The project provides early intervention for primary school children at risk of developing serious emotional and behavioural problems and of subsequent exclusion. To this end the project works with children, parents/carers and schools in a holistic manner. The project also aims to improve home-school relationships, increase teacher understanding and integrate professional practice. Both mainstream and special settings have found the project to be of value.
‘Flow’ experience in the daily lives of sixth-form college students

The Experience Sampling Method was employed to collect data from a sample of 35 sixth-form college students over a period of one week. This methodology involved the subjects answering questions printed in a diary on receipt of signals from a pre-programmed watch. They also completed a package of questionnaires related to psychological well-being. The aim of the study was to investigate whether the experience of situations where high challenge is matched by skill (termed ‘flow’) can be classed as ‘optimal experience’. The results showed that the positive poles of subjective experience tended to cluster in ‘control’ (skills exceeding moderate challenge) rather than flow. However, more optimal experience (considered as high enjoyment) occurred in flow than expected. In addition, optimal experience in flow was characterized by high cognitive involvement. Subjects who experienced flow as optimal experience were found to score significantly higher on measures of psychological well-being than those who did not experience flow as highly enjoyable. The implications are discussed with respect to college students' quality of life and educational experiences.
Disability Statistics in the Developing World: A Reflection on the Meanings in our Numbers

Background The imbalance between the sheer size of the developing world and what little is known about the lives and life circumstances of persons with disabilities living there should command our attention. Method International development initiatives routinely give great priority to the collection of statistical indicators yet even the most basic data on intellectual disability is lacking. In response to the recent adoption of the ‘international classification of function’, numerous initiatives are attempting to expand and improve the quality of disability surveillance. Results We argue that these efforts must not lose sight of the core focus and promise of disability statistics – that of advocacy and the elevation of a disability policy agenda. Conclusions To this end, we weave throughout our analysis of the technical features of surveillance, reflections on the meanings we attach to disability statistics and by extension, disability itself.
Idiosyncratic RiskMatters !

This paper takes a new look at the predictability of stock market returns with risk measures.We ¢nd a signi¢cant positive relation between average stock variance (largely idiosyncratic) and the return on the market. In contrast, the variance of the market has no forecasting power for the market return. These relations persist after we control for macroeconomic variables known to forecast the stock market. The evidence is consistent with models of timevarying risk premia based on background risk and investor heterogeneity. Alternatively, our ¢ndings can be justi¢ed by the option value of equity in the capital structure of the ¢rms. MOSTASSETPRICINGMODELS, starting withMerton’s (1973) ICAPM, suggest a positive relation between risk and return for the aggregate stock market.There is a long empirical literature that has tried to establish the existence of such a tradeo¡ between risk and return for stock market indices. Unfortunately, the results have been inconclusive. Often the relation between risk and return has been found insigni¢cant, and sometimes even negative. The innovation in this paper is to look at average stock risk in addition to market risk.We measure average stock risk in each month similarly to Campbell et al. (2001; hereafter CLMX), as the cross-sectional average of the variances of all the stocks traded in that month.We then run predictive regressions of market returns on this variance measure as well as the variance of the market. Consistent with some previous studies, we ¢nd that market variance has no forecasting power for the market return. However, we do ¢nd a signi¢cant positive relation between average stock variance and the return on the market. THE JOURNAL OF FINANCE VOL.

HRM in the knowledge‐based economy: is there an afterlife?

There is a clear shift in human resource management from a “service provider” to a “business partner”; however, the new requirements and needs can also be met by the line management or external parties. For this reason, the new development is at the same time an immense opportunity and a threat for the HR managers. We are convinced that the HR function in the future will be very different from that in the past. The companies that do not see this and do not act accordingly will have a serious problem with the core assets of the “new economy”: the knowledge workers and the knowledge professionals.
Identification and Expression Analysis of cDNA Encoding a Chloroplast Recombination Protein REC1, the Chloroplast RecA Homologue in Chlamydomonas reinhardtii

Chloroplasts of plant cells have their own genome, and a basic recombination protein homologous to the eubacterial RecA was suggested to be involved in the perpetuation of chloroplast DNA. A candidate cDNA sequence encoding the chloroplast RecA protein was identified from the Kazusa EST database for the unicellular green alga, Chlamydomonas reinhardtii (http://www.kazusa.or.jp/en/plant/chlamy/EST/). Analysis of the cDNA sequence identified an open reading frame (ORF) of 414 amino acids encoding a eubacteria-type RecA protein. Thus the corresponding gene was named REC1. The predicted protein contains an N-terminal extension that does not show any similarity with other RecA proteins. Transient expression of a REC1-sGFP (green fluorescent protein) fusion construct in tobacco cells has indicated that this N-terminal sequence functions as a transit peptide for import into chloroplasts. Since DNA-damaging reagents induced the REC1 mRNA, REC1 was suggested to have roles in DNA recombination and repair of the chloroplast DNA in C. reinhardtii.
Children's story-retelling

Children listen to stories from an early age, and are thus exposed to a rich source of well-formed and well-structured texts. This paper examines the relationship between children's progress in learning to read and their use of specialized linguistic features in retelling stories. The effectiveness of story-retelling is analysed from three per spectives: the use of story structure features, type of recall and the presence of oral and written language features. Children, aged 6 years, are found to include most story structure features in their retellings, though certain types of endings are typically omitted and differences in content are found between good and less skilled readers.
Recreational physical activity and ten-year weight change in a US national cohort.

Clinical research has established that increases in physical activity cause weight loss among the obese, but less is known about the influence of physical activity on longer-term weight change in the general population. Data from the NHANES-I Epidemiologic Follow-up Study (1971-1975 to 1982-1984) were used to examine the relationship between self-reported recreational physical activity level (low, medium, high) and measured weight change after ten years among 3515 men and 5810 women aged 25-74 years. Cross-sectional analyses at both the baseline and follow-up surveys revealed that recreational physical activity was inversely related to body weight. Low recreational physical activity reported at the follow-up survey was strongly related to major weight gain (> 13 kg) that had occurred during the preceding ten years. The estimated relative risk of major weight gain for those in the low activity level at the follow-up survey compared to those in the high activity level was 3.1 (95% Cl = 1.6-6.0) in men and 3.8 (2.3-6.5) in women. In addition, the relative risk for persons whose activity level was low at both the baseline and follow-up surveys was 2.3 (0.9-5.8) in men and 7.1 (2.2-23.3) in women. However, no relationship was found between baseline physical activity level and subsequent weight gain among either men or women. The lack of a relationship may be due to mis-specification of physical activity because of changes in activity over time. These findings suggest that low physical activity may be both a cause and a consequence of weight gain. (ABSTRACT TRUNCATED AT 250 WORDS)
Effects of Phyllanthus muellerianus Leaf-Extract on Steel-Reinforcement Corrosion in 3.5% NaCl-Immersed Concrete

This paper investigates Phyllanthus muellerianus leaf-extract effects on steel-reinforcement corrosion in concrete immersed in 3.5% NaCl, simulating saline/marine environment. Different concentrations of the leaf-extract were admixed in steel-reinforced concrete samples, which were immersed, with normal control, in the test-environment, while positive control samples were immersed in distilled water. Electrochemical measurements of corrosion-rate (by linear-polarization-resistance instrument), corrosion-current (by zero-resistance-ammeter) and corrosion-potential (by high impedance multimeter) were obtained for assessing the reinforcing-steel corrosion. Analyzed results showed that the corrosion-rate exhibited excellent correlation (R = 98.82%, Nash-Sutcliffe Efficiency = 97.66%, ANOVA p-value = 0.0006) with function of the admixture concentration and of the corrosion noise-resistance (ratio of corrosion-potential and corrosion-current standard deviations). The 0.3333% Phyllanthus muellerianus (per weight of cement) exhibited optimal efficiency, η = 97.58% ± 1.28% (experimental) or 95.33% ± 4.25% (predicted), at inhibiting concrete steel-reinforcement corrosion in the test-environment, which compares well with the positive control performance model, η = 97.96% ± 0.03%. The experimental and predicted models followed the Langmuir adsorption isotherm, which indicated physisorption as the Phyllanthus muellerianus leaf-extract adsorption mechanism on the reinforcing-steel. These support suitability of the N-, S-, and O-containing and π-electron rich Phyllanthus muellerianus leaf-extract as an environmentally-friendly inhibitor for effective corrosion-protection of steel-reinforcement in concrete designed for the saline/marine environment.
Short- and long-term joint symbolic dynamics of heart rate and blood pressure in dilated cardiomyopathy

Autonomic cardiovascular control involves complex interactions of heart rate and blood pressure. In patients with dilated cardiomyopathy (DCM), this control is impaired and parameters for its quantification might be of prognostic importance. In this paper, we introduce methods based on joint symbolic dynamics (JSD) for the enhanced analysis of heart rate and blood pressure interactions. To assess the coarse-grained dynamics beat-to-beat changes of heart rate and blood pressure are encoded in symbol strings. Subsequently, the distribution properties of short symbol sequences (words) as well as the scaling properties of the whole symbol string are assessed. The comparison of joint symbolic heart rate and blood pressure dynamics in DCM (n=75) with those in healthy controls (n=75) showed significant changes. Both, the distribution of words and the scaling properties indicate a loss in heart rate dynamics associated with blood pressure regulation in DCM. In conclusion, the analyses of short- and long-term JSDs provide insights into complex physiological heart rate and blood pressure interactions and furthermore reveal patho-physiological cardiovascular control in DCM.
Optimal Control of Nonlinear Systemsto Given

Using optimal control techniques we derive and demonstrate the use of an exact single step control method for directing a nonlinear system to a target orbit and keeping it there. We require that values of the control parameters remain near the uncontrolled settings. The full nonlinearity of the problem in state space variables is retained. The `one step' of the control is typically a composition of known or learned maps over (a) the time required to learn the state, (b) the time to compute the control, and (c) the time to apply the control. No special targeting is required, yet the time to control is quite rapid. Working with the dynamics of a well studied nonlinear electrical circuit, we show how this method works e ciently and accurately in two situations: when the known circuit equations are used, and when control is performed only on a Poincar e section of the reconstructed phase space. In each case, because the control rule is known analytically, the control strategy is computationally e cient while retaining high accuracy. The target locations on the selected target trajectory at each control stage are determined dynamically by the initial conditions and the system dynamics, and the target trajectory is an approximation to an unstable periodic orbit of the uncontrolled system. 1
Urinary kallikrein activity, renal hemodynamics, and electrolyte handling during chronic beta blockade with propranolol in hypertension.

Propranolol has been reported to diminish renal perfusion and impair sodium excretion, but the relationship of these phenomena has not been well characterized during chronic propranolol administration in hypertensive man, nor has the potential involvement of the renal kallikreinkinin system been explored. Fifteen essential hypertensive white men were treated with both placebo and oral propranolol for 1 month each, with dosage titrated for blood pressure control. Propranolol normalized mean arterial pressure (from 112.6 ± 1.9 to 94.0 ± 2 . 8 m m H g , p < 0.01) with associated decrements in glomerular filtration (GFR) by 12% (p < 0.02), renal plasma flow (RPF) by 15% (p < 0.02), and renal blood flow (RBF) by 16% (p < 0.01), while filtration fraction was unchanged. Neither blood urea nitrogen nor serum creatinine were affected. Propranolol also diminished urinary kallikrein excretion (from 9.0 ± 2.7 down to 4.8 ± 1 . 3 esterase units/24 hrs, p < 0.04). Comparison to a group of 10 controls showed a progressive decrease in RBF from normotensive man, to hypertensive man, to propranolol-treated hypertensive man, with a parallel progressive fall in kallikrein excretion in the same three groups. Change in RBFon propranolol correlated inversely with pretreatment RBF (r = —0.91, p < 0.01) and pretreatment urinary catecholamine excretion (r = —0.64, p < 0.01), directly with pretreatment RVR (r = -0 .85 , p < 0.01) and inversely with change in RVR (r = -0.86, p < 0.01). This suggests that: 1) there was a failure of renal perfusion autoregulation; 2) a decrement in RBF was most likely to occur in patients with a relatively "normal" renal vascular tree; and 3) unopposed alpha mediated vasoconstriction was a likely mediator of the RBF fall. Change in RBF did not correlate with change in kallikrein excretion (r = —0.16), while change in kallikrein excretion correlated best with pretreatment kallikrein excretion (r = —0.87, p < 0.01), although not with change in plasma aldosterone concentration or urinary sodium/potassium ratio. Urinary sodium excretion was unimpaired on propranolol (160 ± 21 vs 173 ± 12mEg/24hrs,p> 0.1), even in the face of a diminished glomerular filtration rate, and was sustained by an increase in the fractional excretion of sodium (from 0.75 ± 0.09 to 0.96 ± 0.06%, p < 0.05). This is perhaps related to diminished mineralocorticoid activity as reflected by decreased plasma aldosterone concentration (from 68.4 ± 9.6 to 61.4 ± 16.1 pgAnl, p < 0.02), increased urinary sodium/potassium ratio (from 2.41 ± 0.33 to 3.12 ± 0.30, p < 0.01), and correlation between fractional sodium excretion increment with urinary sodium/potassium ratio increment (r = 0.82, p < 0.01). Preservation of sodium homeostasis was also indicated by constancy in body weight, plasma volume, and blood volume. Kallikrein changes did not correlate with changes in renal sodium handling.
