Diagnosis of Parkinson’s disease using modified grey wolf optimization

This paper presents the Modified Grey Wolf Optimization (MGWO) algorithm which helps with the identification of the symptoms of Parkinson’s disease at a premature stage. Parkinson disease is kind of a movement malady, which if not cured timely can prove to be fatal.Thus it becomes significant to identify Parkinson’s disease at its premature phase so proper medications can provide longevity to patient by controlling the symptoms. In this work, a new model named Modified Grey Wolf Optimization (MGWO) has been proposed grounded on the traditional Grey Wolf Optimizer (GWO), which acts as a search strategy for feature selection. GWO is a meta-heuristic algorithm which is enthused by hunt down behavior of wolves. Random forest, k-nearest neighbor classifier and decision tree espy on selected features. The proposed model is evaluated using various types of datasets of voice, handwriting (spiral and meander) and speech. The put forward algorithm helps in the prediction of Parkinson disease with an estimated accuracy of 94.83%, detection rate of 98.28%, false alarm rate of 16.03% and further aid the individuals to receive a functional treatment at an early stage. The proposed bio-inspired algorithm is stable enough to find out the optimal subset of features. At last the results derived from the evaluation of proposed algorithm on datasets are compared with the results of Optimized Cuttlefish Algorithm (OCFA). The experimental results depict that the proposed algorithm helps in maximizing the accurateness and minimizing the number of features selected.     

Across the Martian Frontier? Thoughts on Planet B,a Martian Safety Valve,and the Earth as Our Body

Even though we are on the precipice of a “bad Anthropocene,” humankind should not colonize Mars. Mars is often depicted as our “Planet B”—an evacuation plan for Earth. But in this time of ecological crisis, theologian Sallie McFague suggests that we think of the Earth as God’s body and take our obligation to care for our common home seriously. Likewise, in contrast to calls for colonization, I contend that two American historical anecdotes—the safety valve theory and the Yellowstone—illustrate why humanity should think less about becoming Martians and instead find meaning and purpose in remaining Earthlings.     

配偶的善意性别偏见对职业女性工作繁荣的影响机制研究：一个有调节的中介模型

本文基于工作-家庭资源模型,采用问卷调查法,收集208份双职工夫妻配对数据,探讨配偶的善意性别偏见对职业女性工作繁荣的中介机制与边界效应。研究结果表明：配偶的善意性别偏见负向预测职业女性的工作繁荣,家庭-工作冲突中介了配偶的善意性别偏见与工作繁荣的关系;同时,职业女性的工作中心性调节了家庭-工作冲突在二者间的中介作用。研究结果对降低职业女性的家庭-工作冲突,减少善意性别偏见,促进工作繁荣有一定的理论和实践意义。     

Consciously monitored grasping is vulnerable to perceptual intrusions

The idea of functional differentiation between vision-for-action and vision-for-perception has been supported by evidence from different domains. According to this account, perception is based on consciously accessible, relative representations, whereas vision-for-action is performed in an analytic, automatic manner. Support for this idea comes from studies that showed that unlike perception, grasping movements are refractory to illusions and to Weber’s law. Yet, interactions between the systems may occur when an action is performed in a less automated fashion. To test this idea, we asked participants to monitor their fingers apertures in flight and to halt their movement for a short duration when they felt that their aperture reached a maximum amount. The results showed that movements in the monitored condition were biased by the Ponzo illusion and showed atypical adherence to Weber's law. These results show that action and perception are more likely to interact when movements are performed in a controlled manner.     

Differences in cognitive performance between informal caregivers and non-caregivers

ABSTRACT

Extensive literature exists documenting the relationship between stress and cognition. Caregiving for an individual with Alzheimer’s disease can be aunique and chronic stress experience due to the increasing dependency of the care-recipient as the disease progresses. The current study examines the relationship between stress and cognitive performance in 47 dementia caregivers compared to 47 noncaregiver control participants matched on age, gender, and education. Participants completed measures assessing stress (measured via the Perceived Stress Scale) and seven domains of cognition including episodic memory, working memory, executive functioning, attention, visuospatial processing, processing speed, and implicit memory. Results showed that caregivers had poorer performance than non-caregivers on certain measures of episodic memory, working memory, and executive functioning; while no significant differences were observed on measures of attention, visuospatial processing, processing speed, or implicit memory. In addition, when controlling for general stress, caregiver performance on measures of processing speed and visuospatial processing was also poorer than non-caregivers. By controlling for levels of general stress that may not be related to caregiving, these results show that differences in cognitive performance are unlikely to be explained by general stress alone.     

Re-reading Anscombe on ‘I’

According to a ‘Straight’ reading of Elizabeth Anscombe’s (1975 Anscombe, E. 1975. “The First Person.” In her Mind and Language, edited by S. Guttenplan, 45–65. Oxford: Oxford University Press. [Google Scholar]) ‘The First Person’, she holds a radically non-referring view of ‘I’. Specifically, ‘I’ is analogous to the expletive ‘it’ in ‘It’s raining’. I argue that this is not her conclusion. Her substantive view, rather is that if what you mean by ‘reference’ is a certain rich and recherché notion tracing to Frege, then ‘I’ is not a referring term. Her methodological point is that one shouldn’t be ‘bewitched by language’ into thinking that ‘I’, because of its syntax, must exhibit ‘reference’ in this sense.     

Exploring mystery: can Christian meditation at school nurture students’ relationships with God?

ABSTRACT

While there is growing international interest in meditation and mindfulness initiatives in schools, little research has focused on exploring the impact of such practices on students’ spirituality. This paper reports data from a mixed method study involving primary school classes engaged in the regular practice of Christian meditation between Years 4 to 6 in Catholic schools in New South Wales, Australia. Student focus group data (n = 114 students) and a student survey (n = 250 students) suggest Christian meditation offers an inclusive and ‘hospitable’ space for many students, where their spiritual well-being can be nurtured, including their connection to God. However, the findings suggest that accompanying dialogue with students around the purpose and possibilities of Christian meditation may help to better situate the practice as a ‘hospitable space’ thus enabling deeper engagement with the spiritual in contemporary Catholic classrooms.     

Transforming churches: the lived religion of religious organizations in a contemporary context

ABSTRACT

This article analyzes patterns of transformation in a specific majority religious institution, the Evangelical Lutheran Church in Denmark (ELCD), through a case study of communicative actions related to new church practices. The argument is that the patterns most often identified in the study of the religion of late-modern individuals, which is an “ever-changing, multifaceted, often messy—even contradictory—amalgam of beliefs and practices” (McGuire 2008, 4), are also relevant when scholars describe changes at the level of religious organizations. Meredith McGuire’s concepts are supplemented with other discussions of the transformation of traditions in a contemporary context. Our research question is: what characterizes the communicative actions concerning the transformation of traditions within the ELCD today? The empirical material consists of communicative actions related to practices associated with Halloween and Valentine’s Day from two distinct contexts: 1) the public debate about the Church in the newspaper The Christian Daily and 2) public announcements in the official online Church calendar. This leads to a discussion of the creative agency of religious institutions as part of the complex pattern of contemporary religion. The article argues in favor of an increased focus on the development of new practices in churches as examples of lived religion at the level of institutional religion.
