The timekeeping of Egyptian outflow clocks

Simple as the outflow clock principle may seem for the measurement of time, its translation into an accurate clock raises formidable technical and conceptual problems. An attempt is made here to reconstruct the Egyptians' consciousness of these problems, and the success of their solutions.     

Social information processing and coping strategies of shy/withdrawn and aggressive children: does friendship matter?

The primary objectives of this investigation were to examine the attributions, emotional reactions, and coping strategies of shy/withdrawn and aggressive girls and boys and to examine whether such social cognitions differ within the relationship context of friendship. Drawn from a sample of fifth and sixth graders (M age = 10.79 years; SD = .77), 78 shy/withdrawn, 76 aggressive, and 85 control children were presented with hypothetical social situations that first involved unfamiliar peers, and then a mutual good friend. Results revealed group and gender differences and similarities, depending on the relationship context. From our findings emerges a central message: friends' involvement during interpersonal challenges or stressors mitigates children's attributions, emotions, and coping responses.     

IMPACT OF FULL-TIME VERSUS PART-TIME INSTRUCTOR STATUS ON COLLEGE STUDENT RETENTION AND ACADEMIC PERFORMANCE IN SEQUENTIAL COURSES

The primary purpose of this study was to examine the relation between full - time or part - time instructor status and college student retention and academic performance in sequential courses . Results indicate that for either developmental or regular courses, college students who take the first course in a sequence from a part - time instructor , and who take the second course in the sequence from a full - time instructor seem underprepared for the second course. By contrast to students experiencing other instructor status combinations (part - time / part - time , full - time / part - time , or full - time / full - time), these students are significantly less likely to either complete or achieve a grade of "C" or better in the second course. Sequential course instructor status, therefore, seems to be a predictor of college student success. Implications for practice pertaining to further research, college students, and institutions are discussed.     

Learning lessons from business games: factors influencing software development

This paper adopts an historical perspective to view the development of business gaming software in the United Kingdom. It argues that, given its use and evolution over three decades, studying this particular software type can generate insights that can be transferred to educational software in general. It also highlights the extent of user-developed software and the accompanying impact on the availability of technology to the user.     

The influence of speech perception,oral language ability,the home literacy environment,and pre-reading knowledge on the growth of phonological sensitivity: A one-year longitudinal investigation

Individual differences in phonologicalsensitivity are among the most powerfulpredictors of early word decoding ability and adeficit in phonological sensitivity is thoughtto be the primary stumbling block for thosechildren who have difficulty learning to read. However, only recently have researchers begunto search for the potential causes andcorrelates in phonological sensitivitydevelopment. In the present one-yearlongitudinal study, the influences of speechperception, oral language ability, emergentliteracy, and the home literacy environment(HLE) on the growth of phonological sensitivitywere examined in a group of 115 four- andfive-year-old children. When the variables wereentered simultaneously into a multipleregression equation, emergent literacy, orallanguage, and the HLE contributed significantunique variance. However, when theautoregressor was controlled, only phonologicalsensitivity at Time 1 and HLE contributedsignificant unique variance to predictinggrowth in phonological sensitivity. Resultsare discussed in terms of their implicationsfor the education of preschool as well asschool-aged children.     

Project interact: A study of patterns of interaction in abusive, neglectful and control families

Child Abuse refers to non-accidental physical and psychological injury to a child under the age of 18 as a result of acts of omission or commission perpetrated by a parent or caretaker. Conceptual problems abound in part because we are clearly dealing with behavior which falls along a continuum of caregiver-child relationships. At one end of the continuum we have seemingly innocuous verbal punishment — disparagement, criticism, threat and ridicule. Or, we have fairly typical forms of physical punishment such as a slap on the hand or a swat on the bottom. Then there are forms of physical punishment that exceed current community standards — hitting the child with a closed fist or with an object such as a razor strap, belt, cord, or paddle, slamming the child against the wall, kicking him, burning the child with a cigarette, scalding the child with hot water, torturing or even killing the child. It is not always clear where a particular case should be placed on this conceptual continuum. What is more devastating to the development of a child, a single occasion where a parent loses control and slams a child across the room, in the process knocking out a tooth and breaking a child's arm, or the persistent day-by-day, month-by-month, year-by-year use of ridicule, criticism and sarcasm toward that child? Nor is it always clear whether acts of omission which are harmful to the child (i.e., neglect) are functionally equivalent to acts of commission that harm the child. This problem of definition and the establishment of a uniform response class is but one of many problems plaguing the systematic study of child abuse. Other problems such as the tendency to dramatize the bizarre and extreme use of physical violence or aggression at the expense of more subtle forms of verbal punishment, the tendency to equate child abuse either with psychopathology, on the one hand, or with poverty, on the other, and the tendency to rely upon impressionistic accounts of behavior also have retarded the accumulation of sound knowledge about the causes, consequences, treatment and prevention of abusive behavior.     

Instructional Investment or Administrative Bloat: The Effects of Charter System Conversion on Resource Allocations and Staffing Patterns

Despite the growing call for local autonomy and flexibility, few scholars have examined the role of school district–level flexibility on resource allocation and staffing patterns. Leveraging the charter system law within the State of Georgia, we utilize a generalized difference-in-differences approach to estimate the impact of flexibility of system-level expenditures and staffing changes. We find evidence of increases in central office spending and staffing post-conversion to a charter system. In addition, we find evidence that local support is replaced by the state-funded supplemental funding.
