钠离子软化水系统的自动控制

在许多工业生产过程中都不能直接应用硬水,对此,常常需要一个硬水软化系统,如纺织印染行业更是如此。该系统通常采用钠离子交换器,控制方法则采用继电控制。本文所述的是如何用可编程控制器（PLC）控制钠离子软水系统,从而提高系统运行的可靠性问题。

Neural Correlates of Face Familiarity in Institutionally Reared Children With Distinctive,Atypical Social Behavior

Although the impact of early adverse experience on neural processing of face familiarity has been studied, research has not taken into account disordered child behavior. This work compared the neural processing of familiar versus strangers' faces in 47 institutionalized children with a mean age of 54 months to determine the effects of (a) the presence versus absence of atypical social behavior and (b) inhibited versus indiscriminant atypical behavior. Results revealed a pattern of cortical hypoactivation in institutionalized children manifesting atypical social behavior and that inhibited children displayed larger neural response to a caregiver's face than to the stranger's, while indiscriminant children did not discriminate between stimuli. These findings suggest that neural correlates of face familiarity are associated with social functioning in institutionalized children.     

Assessing Individual‐Level Impact of Interruptions During Online Testing

With an increase in the number of online tests, the number of interruptions during testing due to unexpected technical issues seems to be on the rise. For example, interruptions occurred during several recent state tests. When interruptions occur, it is important to determine the extent of their impact on the examinees' scores. Researchers such as Hill and Sinharay et al. examined the impact of interruptions at an aggregate level. However, there is a lack of research on the assessment of impact of interruptions at an individual level. We attempt to fill that void. We suggest four methodological approaches, primarily based on statistical hypothesis testing, linear regression, and item response theory, which can provide evidence on the individual‐level impact of interruptions. We perform a realistic simulation study to compare the Type I error rate and power of the suggested approaches. We then apply the approaches to data from the 2013 Indiana Statewide Testing for Educational Progress‐Plus (ISTEP+) test that experienced interruptions.     

A narrative review of Greek myths as interpretative metaphors in educational research and evaluation

This paper reviews a series of Greek myths put forward as cultural narratives that could be used as metaphors or interpretative similes for explanatory and evaluative purposes in educational research and evaluation. These myths have been used in educational research literature, and most of them were found by carrying out an exhaustive search of that literature. In particular, the paper discusses Procrustes, referring to the use of arbitrary evaluative standards; the myth of Mentor, the embodiment of the researcher as facilitator/improver for new, inexperienced researchers; Prometheus, or the archetype of the self-sacrificing researcher; Periphetes, representing the evaluator who is cruel through incompetence; Sisyphus, symbolising the researcher’s anxiousness to achieve his goals; and Ulysses, an archetype for qualitative research.These myths are still absolutely relevant today, after more than 20 centuries, and can be used as powerful explicative frameworks of phenomena in the field of educational research and evaluation. By using myths to interpret educational phenomena, one reconnects contemporary qualitative educational enquiry with its ancient predecessor forms of meaning making.

Education and poverty reduction in the periphery: Can the new development assistance model achieve its goals in lao peoples democratic republic?

Although there has been dramatic economic development in parts of Asia approximately one-third of the Asian population live in poverty. In response to the persistence of poverty a new international development assistance model supported by the Asian Development Bank, the World Bank and many other international agencies is emerging with a major focus on alleviation of po paper will examine educational implications of the new model in one of Asia’s poorest countries, Lao Peoples Democratic Republic. Attention is given to: (1) the changing social, economic and policy contexts within which Lao education functions; (2) the strategic concepts associated with the model of poverty reduction; (3) two potential scenarios of propoor educational change; and (4) assessment of the feasibility of each scenario in increasing the equality of educational and social opportunities for the poor.
