Psychometric Characteristics of the Mini-Mental State Examination among Older Chinese Immigrants

Research Article of International Journal of Aging Research Psychometric Characteristics of the Mini-Mental State Examination among Older Chinese Immigrants Fengyan Tang1*, Ph.D.; Laura E.

In particular, older Chinese Americans are among the fastest growing populations in the U.S., who are at high risk for delayed diagnosis and deficient management of ADRD due to limited knowledge of dementias and barriers to healthcare access. The value of the MMSE as a screening tool in detecting ADRD is well documented in western countries. Yet, little is known about the psychometric characteristics of a Chinese version of the MMSE (CMMSE) in older Chinese immigrants, whose cognitive test performances may relate to cultural and linguistic differences. Purpose: The study aims to assess factor structure and psychometric properties of CMMSE among older Chinese immigrants in the United States. Methods: Participants were recruited from the greater Chicago area in the Population-based Study of Chinese Elderly (PINE). The sample included 3,126 respondents aged 60 or over, who selected Chinese dialects in completing face-to-face interviews. A bifactor analysis was conducted to test unidimensionality of the CMMSE. Rasch modeling was used to assess scale properties. Age, sex, and education were tested for differential item functioning (DIF). Results: A bifactor analysis identified a unidimensional general factor with 30 items, reflecting a single underlying construct of cognitive ...

Logistics Planning and Its Role in Developing Construction Projects in Khartoum State

Review Article of American Journal of Transportation and Logistics Logistics Planning and Its Role in Developing Construction Projects in Khartoum State Omar Ismail Omar Mohammad, Ali Abdullah Alhakem Sudan University of Science and Technology, College of Business Studies, Khartoum, Sudan. There are lots of construction projects been implemented in Khartoum State in the last decades. And, in order to implement construction projects successfully, there should be a perfect flow of materials, services and information related to those projects. The provision of providing projects with those essential needs lies within the concept of the logistics management; so, there will be a critical need for developing perfect planning for logistics services. The provision of supplying construction requirements should be conducted and handled in best manner with all the related aspects including quality, safety, time and cost to the proper execution of the construction projects. Many projects are failed and terminated because problems of the flow of logistics services. Those problems are occurred as result of many factors, but bad planning of logistics services is the one of the most important factors. Thus, in order to implement construction projects, there is a great need for the logistics supply service. Because, without delivering construction inputs in the required manner to the location of project, the project shall never be executed. And, in order to provide the project with the needed inputs in the best way and at a required time, there must be an effective planning for the logistics services of projects; in details, there must be a greater concern with the processes of purchasing, transporting and storing, handling as well as flow of information of all materials that used in the execution of projects. The study finds out that applying project management as well as perfect planning of logistics services play vital roles ...

RECONSTRUCTION OF ANTERIOR FRONTAL WALL AND CONTOURS DEFECTS USING BONE SUBSTITUTE

Research Article of American Journal of Surgical Research and Reviews Reconstruction of anterior frontal wall and contours defects using bone substitute Luigi Clauser, MD,DMD1, Antonio Lucchi, MD,DMD1, Riccardo Luoni Orsi, DMD1and Carolina Sannino MD1 1 Unit of Maxillo-Facial Surgery, Istituto Stomatologico Italiano, Via Pace, 21, 20122 MILANO, Italy Aim: The aim of this article is to report on the safety and long-term efficacy of Cerament® BoneVoid Filler bone substitute for repairing craniofacial bone defects. Post-traumatic cranioplasty is a complex and challenging procedure for all maxillo-craniofacial surgeons and neurosurgeons, especially when repairing large areas. The standard criterion  for repairing small cranial defects is the use autogenous bone from the iliac crest or split calvarial grafts. Autogenous grafts may result in donor-site morbidity, increased  surgical time, reabsorption, blood loss, and  longer recovery time . Alloplastic materials used for bone repair, such as methyl methacrylate,  hydroxyapatite, titanium, or porous polyethylene,  are expected to have optimal properties, including easy adaptation, biocompatibility,  ingrowth of new tissue, stability of shape, and low rate of reabsorption. A cranial implant  should be easily shaped and positioned, allowing  easy tissue  growth. In very wide cranium defects the new technology is a custom made cranial implant constructed three-dimensionally  with different types of materials. However, this procedure is very expensive with various infection rates depending on the  kind of material used and on the chemicophysical composition of the implant. Methods: The authors report the case of a 50-year-old man with a severe deformity of the forehead-supra orbital  area as a result of a previous complex fronto-facial trauma treated in an emergency Unit. Secondary correction and reconstruction of the residual deformities were performed by using Cerament® Bone Void Filler, an  alloplastic biphasic material, composed  of 40% hydroxyapatite, 60% calcium sulfate and the radio-contrast agent iohexol. The unique ratio of hydroxyapatite and calcium ...

Firm Utilization of Perceived Obsolescence

Research article of Global journal of Economics and Business Administration Firm Utilization of Perceived Obsolescence Ace Kim Northern Valley Regional High School at Old Tappan Perceived obsolescence has been displayed experimentally in many situations, but remains understudied theoretically. We develop a model of consumer demand, where firms aim to maximize their profit from consumers who enjoy network benefits from updated products. Firms face two key choices, pricing and whether to obsolete their product through introducing a new mod-el. In this paper, we demonstrate that perceived obsolescence can be an effective strategy for firms, but must be employed with caution. We then use our findings to derive several testable implications that enable businesses to determine for themselves whether perceived obsolescence can be a viable strategy for them. In particular, we categorize the key differences in optimal strategies between firms that sell products with network benefits, such as social media products, as opposed to those that sell status symbols, such as watches. Keywords: Firm Utilization; Perceived Obsolescence ...

The milk – cheese cycle with alpha emitters – pulmonary contribution to the refeeding of the hormonal system in unoptimal conditions

Review Article of International Journal of Traditional and Complementary Medicine The milk – cheese cycle with alpha emitters – pulmonary contribution to the refeeding of the hormonal system in unoptimal conditions Florent Pirot Unaffiliated researcher, 06560 Valbonne, France There is a material truth behind the expression “French people are cheese-eating surrendering monkeys” that involves the higher natural radioactivity in France (averaged) in comparison with the USA, the United Kingdom, Spain and Poland. This comes from the hormone loss related to internal alpha emitting nanoparticulate contamination and involves a compensation with among other things milk drinking and cheese eating. The basic hormone loss can be related to the “surrendering” reputation entirely (testosterone for instance was shown to be destroyed in uranium miners). A secondary cycle emerges to re-establish the sexual difference, where women in these regions typically drink fresh milk whereas men typically eat cheeses that have stayed long in caves and where the hormones have disappeared. This is globally spontaneous. Inhalation of cheese odors serve for cerebral confirmation that hormones have disappeared. That general theorem is a subpart of what was already denominated earlier the meat-pollution cycle for reasons of desire to adopt an easily memorizable name, due to the essentiality of the concept for humankind.
