Bipolar Spectrum Disorders and Self-Concept among Males and Females with Parenting Roles  [PDF]
Frank J. Prerost, Sharon Song
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.34051
Abstract: Bipolar spectrum disorders have been found to produce significant psychosocial costs for individuals and society. Although a number of studies have examined various psychosocial and psychological aspects associated with the bipolar spectrum disorders, the research literature has been extremely limited when focused on the parenting role. This current study examined the self-concept among parents who have been diagnosed with a bipolar spectrum disorder. A group of male and female parents with a diagnosis of a bipolar spectrum disorder were assessed using the Tennessee Self-Concept Scales-2. Another group of males and females without a diagnosis of a bipolar spectrum disorder were also assessed for comparison using the same assessment tool. Compared to the non-bipolar parent group, results showed that participants with a diagnosis of a bipolar spectrum disorder showed a significantly lower self-concept marked with doubts, concerns about academic/work performance, and perceptions of being physically diminished, inadequate, alienated, and unworthy of the family role. Findings from this study showed that parents with a bipolar spectrum disorder expressed negative perceptions related to inadequacy as a person across a number of self-concept dimensions. The results expanded upon current descriptions of the psychological dimensions found among individuals diagnosed with a bipolar spectrum disorder.
Psychological and physical wellness in older adults from the patient perspective  [PDF]
Sharon Song, Frank J. Prerost, Emmanuel Gonzalez, Jonathan Woodin
Health (Health) , 2012, DOI: 10.4236/health.2012.42013
Abstract: The authors of this study examined the relationship between life attitude and physical disease state and found that psychological well being mediated patients’ illness course. Coherence and life control were endorsed as the important components of psychological well being. A multi-dimensional measure of life purpose was administered to 97 older adults on the acute rehabilitation unit of a major medical center in the United States. The severity of their illness burden was computed blindly by a physician rater. Regression analysis was conducted to determine if life attitude was predictive of the symptom ratings and factor analysis was performed on the individual items of the life attitude instrument to highlight the psychological profile of the older adults in this study for whom health challenges were primary. There was a significant relationship between life attitude and disease severity, even though the fit of the model indicated the need for other explanatory factors to fully account for sickness. Factor analysis demonstrated that items defined as measuring coherence and life control explained the largest proportion of total variance. Coherence incorporated the logical integration and consistent understanding of one’s self and the world at large. Life control referred to volition in decision making, exercising of personal responsibility, and the unfolding of life events. The findings suggested that in older adults undergoing medical hospitalization, psychological resilience had a retrospective orientation rather than prospective. The significant influence of life attitude on patients’ physical condition was consistent with clinical observations that the patients who resiliently endure health challenges seem to possess a hardy psychological reserve.
The Beliefs and Attitudes about Deaf Education (BADE) Scale: A Tool for Assessing the Dispositions of Parents and Educators  [PDF]
M. Diane Clark, Sharon Baker, Song Hoa Choi, Thomas E. Allen
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.412150
Abstract:

This paper reports on the development of the Beliefs and Attitudes about Deaf Education (BADE) scale and presents psychometric information derived from the administration of the scale to a national sample of parents, teachers, and program administrators during Wave 1 data collection of the Early Educational Longitudinal Study (EELS). Initially the scale had 47 items; however, 26 items were eliminated during analysis because they were found to be either redundant or not contributing to the most significant underlying latent attitudinal factors. We examined the content of the items loading highly on the factors in this final analysis to determine appropriate subscale labels for the factors. These are as follows: 1) Literacy through Hearing Technologies and/or Visual Support for Speech Comprehension; 2) Visual Language and Bilingualism; 3) Listening and Spoken Language; and 4) Difficulties Associated with Hearing Parents Learning ASL. The BADE scale will be helpful to families with deaf children and the professionals working with them as they explore the different communication options and their own personal beliefs and attitudes toward deaf education.

Primary CNS T-Cell Lymphoma: A Case Report on a Solitary Cerebellar Lesion and Review of Current Relevant Literature  [PDF]
Aden McLaughlin, Sharon Gabizon
Open Journal of Modern Neurosurgery (OJMN) , 2013, DOI: 10.4236/ojmn.2013.32004
Abstract:

Primary central nervous system lymphoma of T-cell lineage (PCNSTL) is an extremely rare entity, with relatively few cases reported in the literature. Presented here is a case of a 44-year-old, HIV negative woman found to have a solitary cerebellar lesion following presentation to the Emergency Department with a fall. The lesion responded to emergent dexamethasone and was followed with serial MRI imaging, which continued to show lesion regression. The lesion was shown to have recurred on MRI 14 months post-presentation and found to be T-cell lymphoma following immunophenotyping and TCR gene rearrangement studies of tissue specimen obtained via excisional biopsy.

Rural nurses’ perceptions of a volunteer program in an acute setting: Volunteers delivering person-centred care for patients with dementia and delirium  [PDF]
Kaye Ervin, Sharon Moore
Open Journal of Nursing (OJN) , 2014, DOI: 10.4236/ojn.2014.41005
Abstract:

Community volunteers were recruited and trained to deliver person-centred care to patients with dementia or delirium in an acute hospital setting, in a small rural Australian hospital. The volunteer program was grounded in action research methodology, and modelled on a previous research project. As a form of evaluation, interviews were conducted with nursing staff eight weeks after implementation of the volunteer program to explore their opinions. Data were analysed through a collaborative process and findings revealed strong benefits from the perspectives of the nursing staff. These benefits included overall improved patient care and improved time management for nursing tasks.

Farming Not Alone: Farmville Play and the Implications on Social Capital  [PDF]
Shaojung Sharon Wang
Social Networking (SN) , 2014, DOI: 10.4236/sn.2014.35028
Abstract: This study explored the relationship between Farmville play and social capital. The implications of social game play for players’ psychological wellness were also assessed. Using survey data collected from Farmville players in Taiwan, it was found that the intensity of Farmville play was positively associated with players’ perceived bridging and bonding social capital. The extent to which intensive Farmville play may lead to the psychological benefits of enhanced life satisfaction and reduced loneliness was discussed. In addition, players who tended to add unacquaintances were more likely to perform better than those who added people they knew. However, connecting with existing contacts through the game provides higher sense of bonding social capital. Implications on the concept of weak and strong ties were also discussed.
Coupled IEEE 802.11ac and TCP Goodput Improvement Using Aggregation and Reverse Direction  [PDF]
Oran Sharon, Yaron Alpert
Wireless Sensor Network (WSN) , 2016, DOI: 10.4236/wsn.2016.87011
Abstract: This paper suggests a new model for the transmission of Transmission Control Protocol (TCP) traffic over IEEE 802.11 using the new features of IEEE 802.11ac. The paper examines the first step in this direction and as such we first consider a single TCP connection, which is typical in a home environment. We show that when the IEEE 802.11ac MAC is aware of QoS TCP traffic, using Reverse Direction improves the TCP Goodput in tens of percentages compared to the traditional contention based channel access. In an error-free channel this improvement is 20% while in an error-prone channel the improvement reaches 60% also using blind retransmission of frames. In our operation modes we also assume the use in Two-Level aggregation scheme, the Automatic Repeat-Request (ARQ) protocol of the IEEE 802.11ac MAC layer, the data rates and the four Access Categories defined in this standard.
A New Aggregation Based Scheduling Method for Rapidly Changing IEEE 802.11ac Wireless Channels  [PDF]
Oran Sharon, Yaron Alpert
Wireless Sensor Network (WSN) , 2016, DOI: 10.4236/wsn.2016.88013
Abstract: In this paper we suggest a novel idea to improve the Throughput of a rapidly changing WiFi channel by exploiting the standard aggregation schemes in IEEE 802.11ac networks. The idea is based on blindly transmitting several copies of the first 4 MAC Protocol Data Units (MPDU) in the Transmission Window. This increases the probability that the window moves forward, enabling the transmission of new MPDUs and resulting in increased Throughput. It turns out that transmitting 2 copies of each of the first 4 MPDUs yields the best Throughput gain, in the order of 50% - 60% in PHY rates of 1.3 - 3.5 Gbps and few hundreds of bytes MPDUs. The proposed idea has advantage over Link Adaptation since it reduces the actual PHY rate only for the transmission of few MPDUs while Link Adaptation reduces the PHY rate for all the transmissions.
Single User MAC Level Throughput Comparision: IEEE 802.11ax vs. IEEE 802.11ac  [PDF]
Oran Sharon, Yaron Alpert
Wireless Sensor Network (WSN) , 2017, DOI: 10.4236/wsn.2017.95009
Abstract: With the ever-increasing range of video and audio applications in portable handheld devices, demand for high throughput in Wi-Fi networks is escalating. In this paper we introduce several novel features defined in next generation WLAN, termed as IEEE 802.11ax standard, and compare between the maximum throughputs received in IEEE 802.11ax and IEEE 802.11ac in a scenario where the AP continuously transmits to one station in the Single User mode. The comparison is done as a function of the modulation/coding schemes in use. In IEEE 802.11ax we consider two levels of frame aggregation. IEEE 802.11ax outperforms IEEE 802.11ac by about 29% and 48% in reliable and unreliable channels respectively.
Scheduling Strategies and Throughput Optimization for the Uplink for IEEE 802.11ax and IEEE 802.11ac Based Networks  [PDF]
Oran Sharon, Yaron Alpert
Wireless Sensor Network (WSN) , 2017, DOI: 10.4236/wsn.2017.98014
Abstract: The new IEEE 802.11 standard, IEEE 802.11ax, has the challenging goal of serving more Uplink (UL) traffic and users as compared with his predecessor IEEE 802.11ac, enabling consistent and reliable streams of data (average throughput) per station. In this paper we explore several new IEEE 802.11ax UL scheduling mechanisms and compare between the maximum throughputs of unidirectional UDP Multi Users (MU) triadic. The evaluation is conducted based on Multiple-Input-Multiple-Output (MIMO) and Orthogonal Frequency Division Multiple Access (OFDMA) transmission multiplexing format in IEEE 802.11ax vs. the CSMA/CA MAC in IEEE 802.11ac in the Single User (SU) and MU modes for 1, 4, 8, 16, 32 and 64 stations scenario in reliable and unreliable channels. The comparison is conducted as a function of the Modulation and Coding Schemes (MCS) in use. In IEEE 802.11ax we consider two new flavors of acknowledgment operation settings, where the maximum acknowledgment windows are 64 or 256 respectively. In SU scenario the throughputs of IEEE 802.11ax are larger than those of IEEE 802.11ac by 64% and 85% in reliable and unreliable channels respectively. In MU-MIMO scenario the throughputs of IEEE 802.11ax are larger than those of IEEE 802.11ac by 263% and 270% in reliable and unreliable channels respectively. Also, as the number of stations increases, the advantage of IEEE 802.11ax in terms of the access delay also increases.
