An investigation of the effects of SFAS No.121 on asset impairment reporting and stock returns (open access)

An investigation of the effects of SFAS No.121 on asset impairment reporting and stock returns

Prior to Statement of Financial Accounting Standards No.121 (SFAS No.121): Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of, managers had substantial discretion concerning the amount and timing of reporting writedowns of long-lived assets. Moreover, the frequency and dollar amount of asset writedown announcements that led to a large “surprise” caused the Financial Accounting Standards Board (FASB) and the Securities and Exchange Commission (SEC) to consider the need for a new standard to guide the recording of impairment of long-lived assets. This study has two primary objectives. First, it investigates the effects of SFAS No.121 on asset impairment reporting, examining whether SFAS No.121 reduces the magnitude and restricts the timing of reporting asset writedowns. Second, the study compares the information content (surprise element) of the asset impairment loss announcement as measured by cumulative abnormal returns (CAR) before and after the issuance of SFAS No.121. The findings provide support for the hypothesis that the FASB's new accounting standard does not affect the magnitude of asset writedown losses. The findings also provide support for the hypothesis that SFAS No. 121 does not affect the management choice of the timing for reporting asset writedowns. In addition, the findings …

From inside the Arab family: What literacy practices occur when raising bilingual and biliterate children? (open access)

From inside the Arab family: What literacy practices occur when raising bilingual and biliterate children?

Living in the United States creates unique challenges in biliteracy and bilingualism for the Arab family. While extant literature provides insight into the literacy interactions and experiences of families from many other cultures now living in the U.S. , there is next to nothing regarding the Arab family literacy experience. Thus, knowledge about the literacy activities Arab families engage in as they gain access to and knowledge of a new culture and language is important. The purpose of this study was to investigate and describe the literacy practices of the Arab families raising bilingual and biliterate children in the U.S. This study , using methodology based on ethnographic approaches, investigated the literacy events, behaviors and interactions which occurred within one Arab family over a 16-week period. A second group of participants were 5 other Arab families living in the U.S. Data sources included video and audio recordings, field notes, observations, journals, informal interviews, and artifacts of children's literacy. The researcher and the participants engaged as co-participants in the research. Findings showed that driving factors behind home literacy practices were religious beliefs and the imminence of return to the home country. Arab mothers were found to yield a heavy influence on …

The Developmental Stages of Concern of Teachers Toward the Implementation of the Information Technology Curriculum in Kuwait (open access)

The Developmental Stages of Concern of Teachers Toward the Implementation of the Information Technology Curriculum in Kuwait

Change is best carried out by individual teachers, and, thus, identifying and resolving teachers’ concerns about an innovation is imperative in guiding the change process to a successful point of implementation. The purpose of this study was to identify concerns that teachers experienced when implementing the Information Technology curriculum in all intermediate schools in Kuwait and to examine the relationships among teachers’ reported stages of concern and other factors, such as gender and experience. The stages of concern, one dimension of the Concerns-Based Adoption Model (CBAM), was applied to reveal teachers’ concerns. The Stages of Concern Questionnaire (SoCQ) and a demographic survey were completed by 248 respondents. The SoCQ measures seven stages of concern that reflect three dimensions: self (awareness, informational, and personal); task (management); and impact (consequence, collaboration, and refocusing Group profile analysis revealed that teachers had four high concerns related to collaboration, personal, refocusing, and informational stages. Teachers also reported low concerns at the management and awareness stages. Both females and males reported collaboration as their greater concern. Teachers with more years of experience reported higher impact concerns. The analysis of individuals’ peak concerns revealed that the majority of the respondents were adopters of the innovation. The analysis …

Perceptions and attributions of child, spousal, and elder abuse. (open access)

Perceptions and attributions of child, spousal, and elder abuse.

Although researchers have studied perceptions regarding sexually abused children, little was known about how other types of abusive events were perceived. This study examined 480 college students' abuse history and perceptions of child, spousal, and elder abuse by varying the respondent, victim, and perpetrator genders. Physical abuse, psychological abuse, and neglect were investigated. Perceptions of abusiveness, seriousness, harm, and responsibility were examined, along with the extent of identification with the victims/perpetrators. Participants viewed spousal abuse as less serious and harmful than other abuse types, especially when perpetrated against a male or by a female. Although able to recognize psychological abuse, students did not fully understand what other abuse types entailed. Individuals also showed a considerable amount of blame toward victims. Results further demonstrated important findings about how ethnic identity/orientation, religious affiliation, and history of abuse related to perceptions of abusive events.

Relations between Child Molesters' Self-Perceptions and Treatment Engagement (open access)

Relations between Child Molesters' Self-Perceptions and Treatment Engagement

Researchers emphasize the role of cognitions in sex offenders' molesting behaviors. Although cognitions are important, little research has examined child molesters' thoughts about themselves in relation to their engagement in treatment. In this study, the NEO-Personality Inventory (NEO-PI-R) was administered to 67 child molesters. Child sexual offenders rated themselves and their view of a typical child molester using two NEO-PI-R versions. The degree to which child sex offenders identify themselves with their view of a typical child molester, and this agreement's relation with engagement in treatment, were investigated. The view that child sex offenders hold about themselves in relation to a typical child molester showed no relation to treatment engagement or length of time in treatment. However, this self-perception was related to the number of children abused.

A Behavioral Economic Analysis of Different Reinforcers: Sound-Clips Versus Points Exchangeable for Money (open access)

A Behavioral Economic Analysis of Different Reinforcers: Sound-Clips Versus Points Exchangeable for Money

Human operant studies frequently use points exchangeable for money as reinforcers. Some studies employ more immediately consumable reinforcers to emulate properties of food reinforcers. This study examined demand for points/money and for sound-clips to compare their economic characteristics. Across four participants, demand was often higher and less elastic for points/money than for sounds. During subsequent exposures at each response requirement, demand for sounds often decreased to a greater degree than demand for points/money. Thus, sound-clips seem less durable than points/money across prices and across repeated exposure to the same price. Response rates for points/money were often higher than for sounds, suggesting that reinforcers that generate higher response rates may be less elastic than reinforcers that generate lower response rates.

An Experimental Investigation on the Effects of Web-Based Instruction/Training on Cognitive and Psychomotor Learning (open access)

An Experimental Investigation on the Effects of Web-Based Instruction/Training on Cognitive and Psychomotor Learning

The purpose of this study was to investigate the effects of web-based instruction (WBI) on cognitive and psychomotor learning. The subjects of the study received two types of instructional methods, WBI (experimental group) and traditional classroom instruction (control group). Each group received 30 minutes of instruction on "Soldering a Circuit Board." The researcher chose this content subject because it involved both cognitive and psychomotor objectives, which suited the purpose of this study. It was hypothesized that there would be no significant difference between the two methods of instruction, and also that there would be no significant interaction effects between methods of instruction and gender. Forty-six subjects from a population of students enrolled in summer classes offered by the Applied Technology, Training and Development (ATTD) program at the University of North Texas voluntarily participated in this study. Random assignment of subjects was applied in this study. A subject matter expert delivered the content for both the experimental and control groups. To measure cognitive variable, a 10 item, multiple-choice test was administered immediately after instruction. To measure the psychomotor variable, a 15-item checklist was utilized by trained judges to evaluate learners’ performances while soldering. The 2 x 2 factorial model with interaction …

Study of Substituted Benzenesulfonate-Containing Layered Double Hydroxides and Investigation of the Hexamethylenetetramine Route of LDH Synthesis (open access)

Study of Substituted Benzenesulfonate-Containing Layered Double Hydroxides and Investigation of the Hexamethylenetetramine Route of LDH Synthesis

Benzenesulfonates, para-substituted with amine, chloride and methyl groups were successfully incorporated into layered double hydroxides of two different compositions, 2:1 Mg-Al LDH and 2:1 Zn-Al LDH. These parent materials were also doped with small amounts of nickel and the differences in the two systems were studied. The hexamethylenetetramine route of layered double hydroxide synthesis was investigated to verify if the mechanism is indeed homogeneous. This included attempting preparation of 2:1 Mg-Al LDH, 2:1 Zn-Al LDH and 2:1 Zn-Cr LDH with two different concentrations of hexamethylenetetramine. The analytical data of the products suggest that the homogeneous precipitation may not be the true mechanism of reaction involved in LDH synthesis by this method.

Solo lyra viol music of Tobias Hume (c. 1579-1645): Historical context and transcription for modern guitar. (open access)

Solo lyra viol music of Tobias Hume (c. 1579-1645): Historical context and transcription for modern guitar.

The seventeenth century in England produced a large and historically significant body of music for the viola da gamba played "lyra-way." Broadly defined, playing "lyra-way" on the viol meant playing from tablature notation in a polyphonic style. Most players of plucked strings such as lute and guitar are familiar with tablature and, as a result, have a decisive advantage when attempting to explore this music. Other factors that make lyra viol repertory potentially attractive to the modern guitarist are its chordal textures, similarities in physical properties of the instruments, and many points of connection regarding the principles of left hand technique. The purpose of this study is two-fold: 1) to illuminate the historical and cultural context of the seventeenth-century English lyra viol music in general and that of Tobias Hume (c. 1579-1645) in particular; and 2) to present an idiomatic transcription for the modern guitar of four representative pieces from Hume's 1605 collection Musicall Humours. Musicall Humours, published in London in 1605, is one of the first and most significant collections of music for the lyra viol. The collection is both ambitious and groundbreaking, being the largest repertory of solo music for the lyra viol by a single composer in …
