The effects of Web site structure: the role of personal difference.

This study examined the effects of Web site structures in terms of advertising effectiveness- memory, attitude, and behavioral intentions. The primary research question for this study is, What type of Web site (Web ad) structure is most effective? In the pilot study, we tested the difference between two Web site structures, linear and interactive, in terms of traditional advertising effectiveness. Results from the pilot study did not support our research expectations. However, differences in terms of memory were noted between the two structures. After re-creating the Web site based on subjects' comments, in the final experiment, we examined the differences between the two structures and the moderating role of personality difference on the effects of Web site structure. The results confirm that participants' attitude, memory, and behavioral intentions were affected differently by the different Web site structures. However, some research hypotheses were not supported by the current data.     

Housing and Child Welfare: Emerging Evidence and Implications for Scaling up Services

Inadequate housing threatens family stability in communities across the United States. This study reviews emerging evidence on housing interventions in the context of scale‐up for the child welfare system. In child welfare, scale‐up refers to the extent to which fully implemented interventions sustainably alleviate family separations associated with housing instability. It incorporates multiple aspects beyond traditional measures of effectiveness including costs, potential reach, local capacities for implementation, and fit within broader social services. The framework further encompasses everyday circumstances faced by service providers, program administrators, and policymakers who allocate resources under conditions of scarcity and uncertainty. The review of current housing interventions reveals a number of systemic constraints for scale‐up in child welfare. Reliance on rental assistance programs limits capacity to address demand, while current practices that target the most vulnerable families may inadvertently diminish effectiveness of the intervention and increase overall demand. Alternative approaches that focus on homelessness prevention and early intervention must be tested in conjunction with community initiatives to increase accessibility of affordable housing. By examining system performance over time, the scalability framework provides an opportunity for more efficient coordination of housing services within and outside of the child welfare system.     

The effect of highly concentrated oxygen administration on cerebral activation levels and lateralization in visuospatial tasks

This study investigated what effect a 30% oxygen administration had on visuospatial cognitive performance and cerebral activation and lateralization using fMRI. Eight college students were selected as the subjects for this study. An oxygen dispenser that provided 21% and 30% oxygen at a constant rate of 8L/min was developed. In order to measure the performance level of visuospatial cognition, two psychological tests were also developed. The experiment consisted of two runs, one for a visuospatial cognition task with normal air (21% oxygen) and the other for a visuospatial cognition task with hyperoxic air (30% oxygen). Functional brain images were taken with a 3T MRI using the single-shot EPI method. The results of the visuospatial behavioral analysis reveal that accuracy rates were enhanced with 30% oxygen administration when compared to 21% oxygen. There were more activations observed at the bilateral occipital, parietal, and frontal lobes with 30% oxygen administration. However, decreased cerebrum lateralization was observed with 30% oxygen administration in the same regions compared with 21% oxygen administration. Thus, it is concluded that the positive effect on the visuospatial cognitive performance level by the highly concentrated oxygen administration resulted from an increase of cerebrum activation and a decrease of cerebrum lateralization.     

Work organization, economic inequality, and depression among nursing assistants: a multilevel modeling approach

To investigate the relationships among the nursing home work environment, emotional strain, and depression in Nursing Assistants in Ohio and West Virginia, this cross-sectional study was conducted with 395 Nurse Assistants in 49 nursing homes in Ohio and West Virginia. Organizational attributes were measured independently at the individual and organizational levels. Multilevel modeling techniques were used to analyze the data. Our methods examined nursing home organizational structure (ownership type, managerial style), and work organization (emotional strain) was examined in relation to the prevalence of depression among nursing assistants. Our findings suggest workplace emotional strain and age are associated with increased odds of depression. Implications of our work include that work in nursing homes for the environment it fosters has a strong effect on emotional strain and depression among Nursing Assistants.     

Relationship of recalled parenting style to self-perception in Korean American college students

The authors examined the relationship of authoritarian, authoritative, and permissive parenting styles and the number of years in the United States with self-perception (academic competence, morality, and self-reliance) as recalled by Korean American college students (N = 144). Authoritative parenting behaviors were most common in Korean American families, followed by authoritarian behaviors, with permissive behaviors a distant 3rd. Authoritative parenting styles and the number of years lived in the United States were predictive of higher academic competence. Authoritarian and permissive parenting styles were predictive of lower self-reliance, whereas number of years lived in the United States was related to higher self-reliance. Those findings provide partial support for generalizing D. Baumrind's (1971) model of parenting styles to Korean American families, and the findings demonstrate the importance of considering acculturation issues in parenting studies.     

A virtual psychiatric ward for orientating patients admitted for the first time

Misconceptions about psychiatric wards frequently cause newly admitted mental patients to stay away from these wards despite their need for treatment. Although ward orientation is typically conducted by nurses in an attempt to help patients to adapt to the new environment, it is considered time-consuming, and the method of orientation and the explanations given may vary among different nurses. This situation calls for a more effective and standardized approach to orientating mental patients on their first admission. To this end, a computer-based interactive virtual environment was developed based on a real psychiatric ward by using virtual reality (VR) technologies. It enables the patient to navigate around to gain understanding about the ward through a virtual guided tour. The effectiveness of this VR orientation approach was investigated by a randomized controlled trial with consecutive sampling. Fifty-four Chinese participants were randomly assigned to undergo ward orientation by either using the VR-based approach or reading text-based electronic information sheets about the ward with a computer. Subjective and objective measures were obtained respectively using the Chinese version of the State-Trait Anxiety Inventory questionnaire and the heart-rate variability measurement before and after the intervention. In addition, a test on the level of understanding about the ward was administered at the end of the session. The results showed that the VR orientation approach is helpful in reducing patients' anxiety while also improving their level of understanding about the ward.     

Holistic versus analytic processing: Evidence for a different approach to processing of Chinese at the word and character levels in Chinese children

Among 30 Hong Kong Chinese fourth graders, sensitivities to character and word constructions were examined in judgment tasks at each level. There were three conditions across both tasks: the real condition, consisting of either actual two-character compound Chinese words or real Chinese compound characters; the reversed condition, with either the order of the two morphemes in the word or the order of the semantic and phonetic radicals in the character reversed; and the random condition, with either two morphemes randomly combined to create arbitrary nonwords or a semantic radical and a phonetic radical randomly combined using correct orthographic rules to create noncharacters. On the word level, children performed worst in the reversed condition and best with real words, whereas on the character level, children performed worst in the random condition and best in the reversed condition. Findings imply a holistic tendency toward word-level processing and an analytic approach to character-level processing in these Chinese children.     

Two models of unawareness: comparing the object-based and the subjective-state-space approaches

This article attempts to motivate a new approach to anti-realism (or nominalism) in the philosophy of mathematics. I will explore the strongest challenges to anti-realism, based on sympathetic interpretations of our intuitions that appear to support realism. I will argue that the current anti-realistic philosophies have not yet met these challenges, and that is why they cannot convince realists. Then, I will introduce a research project for a new, truly naturalistic, and completely scientific approach to philosophy of mathematics. It belongs to anti-realism, but can meet those challenges and can perhaps convince some realists, at least those who are also naturalists.

The compatibility of two generations of American social psychologists

This paper examines Greenwood's (2000) evidence for incompatibility between the early and later American social psychologists on the social conception of cognition, emotion, and behavior. The notion of the autonomy of the individual may offer the key to finding a degree of compatibility between them. Both generations, I argue, fundamentally accept the notion of individual persons as autonomous agents who are able to decide and choose to act and, hence, be responsible for their actions. Philosophical analysis can perhaps inform historians of social psychology on how carefully and critically to reexamine evidence for traditional claims of generational, paradigmatic, and/or foundational splits.
