Resource Usage Protocols for Iterators

We discuss usage protocols for iterator objects that prevent concurrent modifications of the underlying collection while iterators are in progress. We formalize these protocols in Java-like object interfaces, enriched with separation logic contracts. We present examples of iterator clients and proofs that they adhere to the iterator protocol, as well as examples of iterator implementations and proofs that they implement the iterator interface

Culturally Appropriate Assessment of Functional Impairment in Diverse Children: Validation of the ADHD-FX Scale With an At-Risk Community Sample

Objective: In an effort to reduce disparities in ADHD diagnoses and treatment across cultures, the current study sought to establish initial psychometric and cultural properties of the ADHD-FX: a culturally sensitive assessment measure of functional impairment related to ADHD for diverse families. Method: Fifty-four Latino parents (44 mothers and 10 fathers) of school-aged children completed the ADHD-FX, as well as several other measures assessing child behavior and parent acculturation. Results: The ADHD-FX demonstrated adequate reliability (as demonstrated by internal consistency and test–retest reliability), psychometric construct validity (as demonstrated by associations with theoretically related measures), and cultural validity (as demonstrated by or lack of associations with acculturation measures). Conclusion: Initial psychometric and cultural properties suggest that the ADHD-FX is a reliable, valid, and culturally appropriate measure to assess functional impairment related to ADHD (i.e., difficulties with academic achievement, social competence, and familial relationships) in an at-risk, school-aged population

Parental Functioning in Families for Behavioral Parent Training and Importance of Clinically Meaningful Change

Objective/Method: Statistically significant and clinically meaningful effects of behavioral parent training on parental functioning were examined for 20 children with ADHD and their parents who had successfully completed a psychosocial treatment for ADHD. Results/Conclusion: Findings suggest that behavioral parent training resulted in statistically significant improvements in some domains of parenting behavior for both mothers and fathers and in reductions in most domains of parenting stress for mothers. Importantly, clinically meaningful change also was noted for these parental functioning areas, as well as for other domains of parental functioning that did not result in statistically significant findings. Clinical implications are discussed

Seasonal Shoot-Feeding by \u3ci\u3eTomicus Piniperda\u3c/i\u3e (Coleoptera: Scolytidae) in Michigan

Seasonal shoot-feeding by Tomicus piniperda (L.) was monitored at 2­ week intervals on 15 Scotch pine, Pinus sylvestris L., trees from 8 April through 16 November 1994 in southern Michigan. All shoots that showed evidence of T. piniperda attack were removed every two weeks. In 1994, initial spring flight of T. piniperda began on 22 March. At least two live T. piniperda adults were found on the 15 trees on each sampling date from 8 April through 1 November 1994. In addition, at least one freshly attacked, beetle- free shoot was found on each sampling date except for 1 November. The greatest numbers of newly attacked shoots, with or without adults present, were found from mid-June through mid-August. All adults found in April and May were likely parent adults, while those from June onward were primarily brood adults. Therefore, at all times of the year, live T. piniperda adults can be found on live pine trees, either feeding in the shoots or overwintering at the base of the trunk. Implications of these findings are provided in light of the US federal quarantine on T. piniperda

Review of \u3ci\u3eTerrible Justice: Sioux Chiefs and U.S. Soldiers on the Upper Missouri, 1854-1868\u3c/i\u3e by Doreen Chaky

When strong tensions exist between cultures, small incidents can have grave consequences. Thus, in August of 1854, when a Sioux Indian living near Fort Laramie, Nebraska Territory, found a lame cow and killed it to feed his family, a sad chapter began. The cow\u27s emigrant owner complained of his loss to the fort\u27s commander, and Lt. John Grattan was soon on his way to a Sioux encampment to demand that the thief be turned over to face justice. As a cannon rolled into place to reinforce his demand, violence broke out, and thirty soldiers, including Grattan, soon lay dead. Secretary of War Jefferson Davis viewed the event as a deliberate and unprovoked attack, and the following year ordered Brig. Gen. William Harney into the field to punish any Native Americans he could find and remind them to stay clear of white roads and settlements. On September 3, 1855, Harney attacked a camp of a few hundred Sioux hunting buffalo, killing eighty-six of them at the Battle of Blue Water Creek in what is now western Nebraska. Over the following year, Harney traveled through the Northern Plains and hammered out a treaty with a number of bands. Although the treaty was never ratified, it was nonetheless held over the Indians\u27 heads for years as a prerequisite to receiving their annuity goods

This Must Have Been a Grand Sight : George Bent and the Battle of Platte Bridge

The Battle of Platte Bridge, July 26, 1865, is a noteworthy event in the annals of the American Indian Wars. An alliance of Cheyenne, Sioux, and Arapahoe, numbering in excess of 2,000 warriors, traveled three days to a specific military objective, an undertaking unusual both in terms of its magnitude and its level of organization. The battle is also of interest because we have a detailed description of the event written from the Native American viewpoint. This description comes in the form of a number of letters written to George Hyde by Southern Cheyenne George Bent. George Bent, son of the famous trader William Bent and Owl Woman, a Southern Cheyenne, was educated in white schools in Westport, Missouri, and St. Louis. Injured at the Sand Creek Massacre, he joined the hostile forces that traveled north in the spring of 1865 to ally themselves with the Native Americans in the Powder River region. Bent joined the raiding parties that came down to the North Platte in May and June and was a participant in the Battle of Platte Bridge and the Battle of Red Buttes, both of which took place on July 26, 1865. Bent went on to serve as a translator and government liaison to the Cheyenne for decades on the reservation in Oklahoma

Review of \u3ci\u3eHancock\u27s War: Conflict on the Southern Plains\u3c/i\u3e by William Y. Chalfant

Major General Winfield Scott Hancock headed west from Fort Riley in late March of 1867, well prepared to engage the Cheyennes in western Kansas. Seven companies of infantry, eight of cavalry, and an artillery battery accompanied him. A man with political ambitions, he also brought the press along to publicize his efforts. Hancock had neither knowledge nor curiosity about the culture of the people he sought. He wanted to fight them. I think it would be to our advantage to have these Indians refuse the demands I intend to make, a war with the Cheyennes would answer our purpose. Traveling the Santa Fe Trail and picking up supplies at forts along the way, Hancock\u27s forces turned west from Fort Larned, heading up Pawnee Creek. On April 13, at a point about fifty miles north of Fort Dodge, the expedition was confronted by several hundred Cheyenne and Oglala warriors. Speaking through the agent and interpreter Edward Wynkoop, the Indians indicated they would be willing to talk, but begged Hancock to keep the soldiers away from their village as their people were fearful of an attack like the one Chivington had perpetrated at Sand Creek in November of 1864. Hancock ignored their concerns and proceeded to the village, which consisted of some three hundred lodges

Advancing Our Knowledge of ADHD in Latino Children: Psychometric and Cultural Properties of Spanish-Versions of Parental/Family Functioning Measures

The lack of available Spanish versions of assessment measures contributes to insufficient research and underutilization of mental health services for Latino children with Attention-Deficit/Hyperactivity Disorder (ADHD). Thus, the goal of the current study was to examine the psychometric and cultural properties of several Spanish versions of parental/family functioning measures commonly used in comprehensive ADHD assessments (i.e., the Parenting Sense of Competence Scale, Alabama Parenting Questionnaire, and Confusion, Hubbub, and Order Scale). Participants included 68 Spanish-speaking, Latino parents in Southeast Wisconsin. In general, the Spanish translations of the measures demonstrated good reliability and validity. Furthermore, the psychometrically-sound measures were significantly related to acculturation as predicted, suggesting that the scales are not only psychometrically valid, but also culturally valid for use with Spanish-speaking, Latino families
