This paper presents S-TRAP, a novel block-level CDP (Continuous Data Protection) recovery mechanism based on TRAP. In accordance with a certain time interval L , S-TRAP breaks down the parity chain of TRAP and generates new sub-chains. Besides, S-TRAP introduces previous block cache which can reduce the negative impact on the primary storage system. Both mathematical analysis and experimental evaluation demonstrate that S-TRAP not only has the advantage of high recovery efficiency and reliability, but also further reduces the parity storage usage. Even more important, S-TRAP reduces the negative impacts on primary storage system performance to a large extent.

Abstract Achieving a long-lasting impact on health outcomes requires focus not just on patient care, but also on community approaches aimed at improving population health through addressing gaps in Social Determinants of Health (SDOH). SDOH have been found to disproportionately affect those in low-income brackets and the disabled to varying degrees based on locale. The purpose of this exploratory research was to determine 1) which SDOH have the greatest negative impact on disabled and elderly populations within four targeted states (Iowa, Ohio, Minnesota, Wisconsin) and 2) if there is a difference in negative SDOH impact between metro and non-metro locales. Individual-level data were obtained from disabled persons aged 65 years or older who responded to the Centers for Disease Control and Prevention's 2017 Behavioral Risk Factor Surveillance System (BRFSS) survey. Utilizing these data, frequency distributions were obtained using SPSS. Rank order variation in SDOH was observed among four Midwestern states and between metro vs. non-metro geographic regions. Frequency distributions assisted in identifying the greatest negative impacting SDOH on elderly disabled populations. An examination of the rank order tables allowed the investigator to accurately assess the rank of negative impacts. There were variabilities in responses to questions with moving two or more times within 12 months having the lowest negative impact. When regrouped based upon SDOH negative impacts, were you able to pay your bills was the most frequent SDOH across all states. Feeling unsafe or extremely unsafe in your neighborhood was the highest negatively impacted SDOH within states. Cited determinants in three categories were highest in Ohio. Ohio also had the highest proportion of negatively impacted SDOH across all states. No money for balanced meals was a close second SDOH across states.

This study is part of a broader phenomenological study on the experiences of family caregivers and their care recipients. There is a general paucity of research on the experiences of primary and secondary caregivers, and the negative impact of elderly care on caregivers in the urban poor settings in Ghana. This study explored primary and secondary caregivers’ challenges and coping strategies in the urban poor context in Accra, Ghana. This study was conducted in Ga Mashie. Thirty-one caregivers were interviewed. A phenomenological analysis was conducted using NVivo 10. Primary and secondary caregivers experienced economic, physical, social, and psychological burdens. Also, caregivers used spirituality and perseverance to cope with their challenges. The findings demonstrate that caregivers’ challenges varied by type of caregiver. Researchers and policymakers should consider the type of caregiver when designing interventions to mitigate the negative impacts of family caregiving on caregivers.

Abstract The COVID-19 pandemic represents an unprecedented threat to individual and public health, psychosocial, and economic well-being, although COVID-19 threats and impacts may vary by age and other demographic characteristics. Although greater age is a risk factor for greater COVID-19 disease severity, we know little about the association between age and perceived and experienced COVID-19 threats and their association to well-being. These associations were examined in an ongoing 3-wave investigation of over 1,700 U.S. adults (age 18-89; 53.1% female). Wave 1 analyses indicate no significant age variation in perceived threat of COVID-19 infection, with older and younger individuals reporting similar levels of COVID-19 infection threat. However, greater age was associated with lower perceived negative impact on financial and needed resources (r=-.10**), lower perceptions of COVID-19 induced harm to mental well-being (r=-.17**), and more favorable well-being profiles. Greater perceived COVID-19 threat and negative impact on resources and well-being were linked to greater feelings of stress (β’s=.45 to .68***), loneliness (β’s=.24 to .49***), social well-being (β’s=-.19 to -.36***), and poor sleep quality (β’s=.34 to .51***). These associations did not vary with age with the exception that older individuals showed stronger links between COVID-19 threat and impacts and poorer sleep quality. Ongoing analyses are examining whether these associations persist over time. Despite older adults’ greater risk of COVID-19 disease severity and mortality, older age did not appear to be linked to greater perceived COVID-19 threat or impacts, nor linkages to ill-being, with the possible exception of potential greater vulnerability to poor sleep quality.

The Impact

Drawing from the negative impacts of the perception of organizational politics (POP) on the literature on organizational outcomes, the model proposed in this study examines a nonlinear relationship of POP on job satisfaction. In a similar way, ingratiation as a moderator variable is tested. Based on a survey of 240 state-owned enterprise employees in Indonesia, this study finds that POP exhibits an inverted U-shaped relationship with job satisfaction. Low and high levels of POP have a negative impact on job satisfaction. Nevertheless, our most intriguing finding is that ingratiation behavior not only strengthens POP’s effects on job satisfaction, but can also alter the direction of the relationship in which its shape is represented by a U-shape. This shape indicates that the employees who engage in high levels of ingratiation as a coping mechanism and adaptive strategy tend to do so when they perceive high degrees of POP. These results are then discussed from a cross-cultural perspective as an attempt to explain the legitimacy of ingratiation in Indonesia.

Abstract Therriault, T. W., and Herborg, L-M. 2008. Predicting the potential distribution of the vase tunicate Ciona intestinalis in Canadian waters: informing a risk assessment. – ICES Journal of Marine Science, 65: 788–794. A crucial step in characterizing the potential risk posed by non-native species is determining whether a potential invader can establish in the introduced range and what its potential distribution could be. To this end, various environmental models ranging from simple to complex have been applied to predict the potential distribution of an invader, with varying levels of success. Recently, in marine waters, tunicates have received much attention, largely because of their negative impacts on shellfish aquaculture. One of these species is the vase tunicate Ciona intestinalis, which recently has had a negative impact on aquaculture operations in Atlantic Canada and could pose a risk in Pacific Canada. To inform the risk assessment of this species, we evaluated two different types of environmental model. Simple models based on reported temperature or salinity tolerances were relatively uninformative, because almost all waters were deemed suitable. In contrast, a more complex genetic algorithm for rule-set prediction (GARP) environmental niche model, based on documented Canadian occurrence points, provided informative projections of the potential distribution in Canadian waters. In addition to informing risk assessments, these predictions can be used to focus monitoring activities, particularly towards vectors that could transport C. intestinalis to these favourable environments.

Construction industry creates an environment for people's lives. On the other hand, construction activities have a negative impact on various aspects of the environment. It consumes natural raw materials, significantly contributes to carbon footprint, waste, etc. Appropriate choice of constructional, material, technical, technological and environmental parameters of buildings can partially reduce this negative impacts. By designing, implementing and using wood-based constructions it is possible to reduce the negative impact in the area of construction waste generation. Currently, the construction market offers a large number of construction systems of wooden buildings, which have both strengths and weaknesses. In this paper are identified construction systems of wooden buildings offered on the Slovak construction market. The aim of the paper is a detailed identification of construction waste generation during the realization of particular wooden structures and monitoring of waste generation in production factory (off site) and on construction site (on site) during the construction of wooden buildings. Based on the obtained information, the individual construction systems of wood-based constructions are compared in terms of construction waste generation

  Insight Journal Vol. 7 DOI: 10.24191/ij.v7i1.58 This research study is endeavoured to discover the factors that will lead the consumers’ staying intention at green hotels, especially of those who practise the Shariah Law (Islamic green hotels). Nowadays, there has been an increase in public concern regarding environmental issues. Consumers are more environmentally aware than they were in past decades. Hotels are among the largest contributors of energy consumers in the tertiary building sector, which contribute to some negative impacts to the earth at the same time. The most obvious negative impact of hotels on environment are solid waste generation and disposal. Therefore, numerous consumers are supportive of green consumption and consider it as a successful method to protect the environment. In Islamic green hotels, Muslim-friendly amenities have also been provided to protect Muslims travellers’ welfare that is by providing them a comfortable prayer room, the Holy Quran and Islamic practices booklets, prayer mats and a direction of Qibla. A set of questionnaires was distributed to 256 respondents among the community and tourists in Kuching, Sarawak. The dependent variable in this study was consumers’ staying intention while the independent variables were green image, green satisfaction, Muslim amenities and lifestyle and price fairness. This research study also made use of the Statistical Package for Social Science (SPSS) software to analyse the result based on the questionnaires distributed to the respondents. Based on the result of analysis, it is shown that the green image and green satisfaction were found of having a positive significant that influence the consumers’ staying intention at the Islamic green hotels. Besides that, Muslim amenities and lifestyle was also found to have a positive significant impact that influences the consumers’ staying intention. Most Muslims were likely to choose a destination with Islamic practice to fulfil their daily duties. However, green price fairness did not significantly influence the consumers’ staying intention. This is because if green image, green satisfaction, Muslim amenities, and lifestyle meet the requirements of the Muslim tourists, they would not be affected by the price. As a matter of fact, price may be the least factor of consideration by the tourists in choosing a hotel to stay.
