The Construct of Change in Close Relationships  [PDF]
Anna H. C. Neo, Weining C. Chang
Psychology (PSYCH) , 2017, DOI: 10.4236/psych.2017.88077
Abstract: Relationship beliefs are individual’s cognitive representations of interpersonal relationships found to contribute to the functioning, development and resolution of close relationships. The present study extends Rogge and Bradbury’s (2002) multidimensional approach to the understanding of relationship change by exploring the construct of change that involves both intentional interventions and naturally occurring changes. We conducted two studies on Singaporean Chinese adults, aged 18 to 29 years old. Study 1 explored the laypeople’s construct of relationship change through qualitative interviews. The responses were utilized to develop the Relationship Beliefs about Change (RBC) scale. Study 2 aimed to validate the RBC scale and found three dimensions: Agent of Change (AGC), Inevitable Change (IC), and Managing Change (MC). The RBC demonstrated adequate psychometric properties as an assessment of change beliefs in relationship. The scale revealed a multifaceted system of beliefs consisting of the constantly changing nature of relationship: AGC—who or what changes; IC—the belief system about change, and MC—the need for intervention to curb changes in relationships.

Open Journal of Medical Psychology (OJMP) , 2017, DOI: 10.4236/ojmp.2017.64018
Abstract: Introduction: It is estimated that more than 330 million persons are living with HIV-infection globally and in Nigeria about 3.4 million persons are living with the infection, with an annual death rate of 180,000. Psychological morbidity often accompanies chronic illnesses and may be associated with substance abuse, poor health seeking behaviour and adherence to treatment program; it may worsen existing health problems and the overall quality of life. Until the burden is effectively identified, intervention cannot be planned. Until there is cure, the goal is to manage and cope effectively with HIV-infection. Little if any studies have been done in this area in the North West geopolitical zone of Nigeria, the study would help to identify high risk groups and prevent the progression and spread of the infection. Objectives: To identify HIV-infected persons with psychological morbidity, accessing HIV-clinic at Shika Hospital, Zaria, Kaduna State; and analyze their socio-demographic profile. Methodology: A cross sectional descriptive study was carried out to assess and analyze the socio-demographic characteristics of HIV-infected persons attending Shika hospital Zaria Nigeria, who screened positive for psychological morbidity. A total of 109 HIV-infected persons receiving HAART at Shika clinic, Zaria, Kaduna State, Nigeria, were administered questionnaires; the General Health Questionnaire (GHQ-12) measuring psychological morbidity and socio-demographic data. The participants ranged in age between 18 and 75 years. Results: Data were analyzed using SPSS software 15. Both descriptive and inferential Statistics were performed on the data. Results indicate a total prevalence rate of psychological morbidity of 78 percent among participants. Of this, about 16.2 percent were severely distressed, 25.1 percent moderately distressed and 36.7 percent were mildly distressed. The females were more likely to be distressed than men (65 percent vs. 35 percent of those with psychological morbidity, OR = 3.5 CI 95 percent). It was (57 percent) for patients whose HIV-infection was of relatively shorter duration (less than 4years) than (43 percent) those of longer duration (5 years and above; OR = 1.7, CI 95 percent = 1.1 - 3.5). The age group (18 - 40 years) was more likely to screen positive for psychological morbidity (58.3 percent vs. 41.7 percent, OR = 2.4, CI 95 percent), than the age group (41 - 75 years). On the other hand, Christians were more likely than Muslims (55 percent vs. 45 percent, OR = 1.5, CI 95 percent = 1.1 - 3) to be distressed. For married patients with
Perception and Information Seeking Behaviour of Rural Households towards Health Promoting Practices in Maigana District of Kaduna State, Nigeria  [PDF]

Open Journal of Medical Psychology (OJMP) , 2017, DOI: 10.4236/ojmp.2017.64019
Abstract: Information is valuable, increases understanding and reduces uncertainty. Limited knowledge and access to health promoting and disease prevention programmes are more pronounced in rural than urban areas of Nigeria. Furthermore, the paucity of healthcare services in these rural communities also contributes to the prevalence of health challenges in the rural sector. This study investigated the perception and information seeking behavior of rural households in Maigana District of Kaduna State, Nigeria towards health promoting practices. A random sample of 152 respondents selected from five of eleven wards in the district was interviewed using a pre-tested structured questionnaire. The results, based on a 4-point Likert type scale and benchmark of 2.5 showed a very poor perception of health promoting practices among the respondents. Also, the information needs of the respondents were shown to be enormous. Three of the six socio-demographic variables regressed were found to significantly influence the information seeking behavior of the respondents regarding health promoting practices. Constraints limiting the embracement of health promoting practices were identified and measures aimed at promoting healthier living standards in rural communities were recommended. The study concludes that vast knowledge gaps do exist coupled with the poor perception of HPPs by the respondents.

Terrestrial ground temperature variations in relation to solar magnetic variability, including the present Schwabe cycle  [PDF]
C. de Jager, H. Nieuwenhuijzen
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.510136
Abstract: We study the influence of solar activity on climate by investigating the relation between the long-term components of the total magnetic fluxes of both the equatorial and polar fields of the sun and the average terrestrial ground temperature. This is done for the period 1610 (beginning of systematic sunspot observations) till present with an extrapolation to 2015. It is found that from 1610 till about the first half of the 20th century the variation of the long-term average terrestrial ground temperatures is chiefly due to the variation of solar activity, with seemingly random, non-solar residuals. Around 2007, after the Grand Maximum of the 20th century, solar activity, after having gone through a remarkable transition period (~2005 to ~2010), entered into another Grand Episode. That Episode started with the present solar cycle, in shape comparable to the equally weak Schwabe cycle #14. The transition period, in combination with the present low Schwabe cycle causes that the solar contribution to the total terrestrial temperature variation is small during the on-going decade. It results in a slowing down of the rise of temperature after ~2005.
Does Human Resource Management Help a Company’s Financial Operating Result?  [PDF]
Rob. C. H. van Otterlo
Journal of Service Science and Management (JSSM) , 2013, DOI: 10.4236/jssm.2013.65031
Abstract:

Human Resource Management (HRM) is widely believed to have a positive effect on the performance of company. However, empirical proof of this is hard to come by. In this study, we try to establish a linkage between HRM and financial output of two case studies in the profit sector. To do this, we have developed a performance measurement system that is tailored to the specific needs of measuring HRM-performance in for-profit of company. Although we do not try to generalize the outcome of this study, it looks promising in the way that more case studies should be conducted using this specific performance measurement system. If nothing else, management and controllers could use the system to evaluate the performance of their HRM-tools.

Design and Analysis of Microstrip Antenna Arrays in Composite Laminated Substrates  [PDF]
S. M. Yang, C. H. Huang, C. C. Hong
Journal of Electromagnetic Analysis and Applications (JEMAA) , 2014, DOI: 10.4236/jemaa.2014.66011
Abstract:

In high performance aerospace systems where weight and aerodynamics are of major concern, fiber reinforced composite laminates can be tailored to achieve desirable mechanical properties and accommodate low-profile microstrip antenna. This work aims at the analysis of microstrip antenna array embedded in composite laminated substrates. The size of a single antenna is first calculated by spectral domain analysis to model the effects of the substrate’s electromagnetic property and the orientation of the laminate layers. The antenna array as well as the feed network, composed of microstrip transmission lines, quarter wave-length impedance transformers, and T-junction power dividers, is then tuned to accommodate the effects of the coupling between the antenna elements and the feed network loss. The performance of the 1 × 2, 1 × 4, and 1 × 8 linear array and 2 × 2 and 2 × 4 planar array are shown to have better directivity when embedded in composite laminated substrate compared with those when attached on isotropic substrate. Both 1 × 2 and 1 × 4 arrays at 2.4 GHz are validated experimentally to achieve better coverage.

Engineering (ENG) , 2016, DOI: 10.4236/eng.2016.81003
Abstract: Earth resources are the essential basis for an economy of a country and well-being of her citizens. Their exploitation is a key factor in economic growth and development of the nation, but one that can have serious negative environmental and socio-economic impacts. Therefore it is important to understand their origin/occurrence and exploitation in terms of environmental sustainability. The human society has profited from exploitation of earth resources, precisely when energy use became much more efficient during the industrial era. Some of these earth resources (renewable and non-renewable) are oil and gas, coal, water, metal ore, wind, air etc. and their methods of exploitation are surface and subsurface mining methods [1]. Thus the geological perspectives of earth resources refer to origin and occurrence of these earth resources while the engineering perspectives refer to the processes involved in the extraction (mining), processing and utilization of the resources. To fulfill the requirement of sustainable development, the efficiency with which resources are utilized has to be improved. The main concerns associated with earth resources, therefore, are generally the costs and environmental impacts of extracting, transporting, and refining them. The economics of earth resources deals with the supply, demand and allocation of the resources.
