Machine learning in eigensubspace for network path identification and flow forecast

This paper emphasizes the joint time-frequency interpretation of eigensubspace representation for network statistics as features for identiﬁcation and tracking trafﬁc ﬂows based on the link level activity. Eigencoefﬁcients (frequency domain feature) and eigenvector components (time domain feature) are jointly utilized to quantify their combined signiﬁcance on the representation of each link data (each component of the link trafﬁc vector) in the eigensubspace . The joint time-frequency method is employed to analyze the trafﬁc data obtained from the Internet2 network. It is shown that the analysis with link-level resolution brings advantages for network trafﬁc engineering applications. A machine learning method is investigated to identify network paths using eigenanalysis of link statistics as the feature set. The merit of the method is validated by experimental studies of the network scenarios considered in the paper. Eigenvectors and eigenﬂows in the subspace are jointly used as factors (features) for linear regression to forecast the network link trafﬁc. It is demonstrated that the eigensubspace based auto-regressive order two, AR (2), predictor is superior to the time-domain based predictor to forecast the link level trafﬁc of a network.
Advancing African Psychology: An Exploration of African American College Students’ Definitions and Use of Spirit in Times of Stress

Although religion and spirituality are understood as multidimensional resources in times of stress, less is known about the culturally relevant concept of spirit in African psychology. Eighteen African American college students completed written open-ended questionnaires about how—in relation to religion and spirituality—they define and use spirit in response to stress. Qualitative constant comparison analysis of the data yielded themes defining spirit and its use in response to stress. The definition of spirit was described distinctly as energy, while it overlapped with religion and spirituality as a connection with or a search for God. Spirit also overlapped with religion as faith and spirituality as a feeling/sense/guiding consciousness or inner thought within oneself, and soul. Themes for the use of spirit in response to stress were descriptive of optimal functioning and included (a) thoughts of asking God for help, (b) prayer, (c) positive emotions, (d) self-affirming thoughts, and (e) productive activity. The findings are discussed regarding spirit as a distinct yet overlapping concept with religion and spirituality that has implications for research and practice within African psychology.
Decreasing trends in consecutive‐day tornado events in the United States

Days with many tornadoes in the United States have become more common over time. These days tend to occur in consecutive‐day tornado events, but trends in the characteristics of consecutive‐day tornado events have not been documented. The Mann–Kendall trend test and Theil–Sen slope estimator were used in this study to detect trends and estimate rates of change over time in multiple metrics of consecutive‐day tornado events. Results show that the number of consecutive‐day events, the number of days occurring in consecutive‐day events, and the number of tornadoes occurring in consecutive‐day events have decreased over time. The percentages of annual tornadoes and tornado‐days occurring in consecutive‐day events have also decreased over time. These trends suggest that the percentage of tornadoes occurring on isolated days has, alternatively, increased over time.
Exploration of Preservice Teacher Attitudes Towards Disability

ABSTRACT Community colleges have a significant role in preparing early childhood educators who will likely one day teach in inclusive classrooms. Inclusive education models educate children with disabilities alongside their non-disabled peers, promoting acceptance, decreasing discrimination, and fostering a society in which everyone lives and works together. Teachers’ experiences in working with children who have disabilities and attitudes toward disability affect teacher behavior and practice. The preservice teacher training years are important for preparing teacher candidates to teach in inclusive classrooms; thus, it is imperative that teacher educators have knowledge of methods that will positively impact teacher attitudes toward disability and offer experiences in classrooms with children who have disabilities. This study investigated the effect of an introductory special education course at a community college that included a fieldwork component in inclusive classrooms, as well as the ability status of the course’s professor on early childhood preservice teachers’ attitudes toward disability. Mixed methods pre- and posttest data was collected from 108 students enrolled in a large urban community college’s teacher education program. Students attended class in-person with a professor who had a disability, in-person with a professor who did not have a disability, or online. Posttest results indicated that student attitudes toward disability became significantly more favorable after completing the course, but the professor’s disability status did not influence the change. While there were positive changes, some students continued to objectify disability and perceive disability with a deficit lens. Further research is needed to foster positive attitudes toward disability in teachers.
Effect Of Peer Tutoring On Students’ Academic Achievement In Office Technology And Mangement In Nigerian Polytechnics

Students of Office Technology and Management (OTM) in Nigerian polytechnics have consistently performed below expectations both academically and at work. This may be attributed to use of inappropriate instructional method. The need to improve this situation necessitated the research on effects of peer tutoring on students’ academic achievement in OTM in Nigerian polytechnics. Using a research question to guide the study, and a null hypothesis was tested at 0.05 level of significance. A non-randomized quasi experimental research design, adopting pre-test; post-test non-equivalent control group design was used. South West Nigeria was the region of the research work with a populace of 503 National Diploma Year II (ND II) OTM students in four federal polytechnics. Using cluster random sampling, a sample of the intact classes of 227 students from two states in the area of the study was drawn. Three OTM experts validated the “Office Technology and Management Achievement Test (OTMAT)” 100 items instrument for face and content validity. The Experts input modified some items and cancelled some which reduced 140 test items to 100 used for collecting data. Descriptive statistics of mean was used to analyze data and to respond to the research question while t-test and Analysis of Covariance were used to test the null hypothesis. Kuder-Richardson Formula 21 was adopted to establish internal consistency and reliability of the instrument which yielded a coefficient of 0.86. The research showed that Peer Tutoring Instructional Technique (PTIT) has higher positive effects on students’ academic achievement in OTM than Teacher-dominated Instructional Approach (TDIA), thus it can enhance students’ academic achievement in OTM. It was, therefore, suggested that OTM lecturers should include the use of Peer Tutoring Instructional Technique to boost learning in teaching their students.
Determinants of Anti-Corruption Disclosure in State-Owned Enterprise in Indonesia

Corruption within corporations has become an important issue in academic and public debate. This study examines the impact of political connections and the gender of executives on anti-corruption disclosures (ACD). Using a sample of 29 state-owned enterprises (SOEs) listed on the BEI (Indonesia Stock Exchange) from 2015 to 2017, we ran a multiple regression analysis that shows political connections negatively affect ACD. The findings also show that executive gender, specifically having women on the boards of SOEs in Indonesia, does not affect the impact of political connections on ACD. This research makes an important contribution to the literature by developing and empirically testing the study of anti-corruption disclosure within legitimacy theory.
Minding the gap: academic outcomes from pre-college programs

ABSTRACT This paper analyzes the effects of assignment to a one-year college preparatory program on academic performance in college. We use a large dataset of United States Naval Academy students from the 1988 to 2018 graduating classes, of which a little over 22% received remediation. Exploiting the Academy's unique admissions criteria, we instrument for pre-college treatment using the number and quality of other applicants originating from the same Congressional district. We find that these pre-college programs promote significant but short-lived improvements in academic grades. They also can encourage students to choose STEM-oriented majors, and promote retention by lowering voluntary exits.
LIPOSTRUCTURE: EXPERIENCE OF THE DEPARTMENT OF PLASTIC SURGERY OF THE MOHAMMED VI UNIVERSITY TEACHING HOSPITAL OF MARRAKESH

This is a descriptive retrospective study of 42 cases of patients who underwent the lipostructure procedure at the Department of Plastic Surgery of Mohammed VI Teaching Hospital of Marrakesh, over a period of 6 years, from January 2012 to December 2017. It aims to report our experience, and to review the procedure, applications, and outcomes of lipostructure. A total of 61 procedures were performed. The average age of our patients was 28.78 years. A female predominance was noted (86%). The main indications were: burn sequelae (33%), trauma sequelae (17%), infection sequelae (10%) and facial rejuvenation (10%). In terms of local conditions, most of our patients suffered from skin scars (61.9%), atrophy (14.28%), wrinkles (9.52%), facial asymmetries (7.14%), and nasal deformities (7.14%). The samples was mainly harvested from the abdomen (42%), followed by the trochanteric region (saddle bags) in 38% of cases. 67.21% of the samples were harvested from a single donor site. The average volume collected was 74.52 ml. All the samples were centrifuged by the Regenlab system. 52% of the lipostructure procedures were performed on the face, with an average injected volume of 23.25ml. 42.62% of the lipostructures were associated with an injection of PRP, and 6.55% with a facelift.
Industry as Contexts or Theory? A Systematic and Meta-Analysis of Status and Directions of Organizational Citizenship Behaviors in Hospitality

Owing to the service-oriented nature of hospitality organizations, organizational citizenship behavior (OCB) has drawn increasing attention from hospitality researchers over the last two decades. Taking a systematic and meta-analytical approach, this study presents a comprehensive picture of the status, conceptual and measurement frameworks, fundamental theories, method, antecedents, consequences, and meta-analytical relationships among popular variables. In addition, the study points out research gaps and future directions for hospitality OCB research, drawing on comparison with mainstream OCB literature. In particular, there is a need for more holistic, reliable, and validated OCB frameworks and measures for different hospitality contexts; a need for research on the consequences of OCB at the level of customers, coworkers, and employees; and more rigorous research methodologies. The findings further suggest that the unique characteristics of hospitality organizations not only provide meaningful contexts but also broaden and deepen the scope of OCB theories.
On the kinematics and timing of Rodinia breakup: a possible rift–transform junction of Cryogenian age at the southwest cape of Congo Craton (northwest Namibia)

After tilt correction for Ediacaran thick-skinned folding, a pair of Cryogenian half grabens at the autochthonous southwest cape of Congo Craton (CC) in northwest Namibia restore to different orientations. Toekoms sub-basin trended east-northeast, parallel to Northern Zone (NZ) of Damara belt, and was bounded by a normal-sense growth fault (2 290 m throw) dipping 57° toward CC. Soutput sub-basin trended northwest, oblique to NZ and to north-northwest-trending Kaoko Belt. It was bounded by a growth fault (750 m down-dip throw) dipping steeply (~75°) toward CC. Soutput growth fault could be an oblique (splay) fault connecting a Cryogenian rift zone in NZ with a sinistral transform zone in Kaoko Belt. A transform origin for the Kaoko margin accords with its magma-poor abrupt shelf-to-basin change implying mechanical strength, unlike the magma-rich southern margin where a gradual shelf-to-basin change implies a mechanically weak extended margin. A rift−transform junction is kinematically compatible with observed north-northwest−south-southeast Cryogenian crustal stretching within CC. Post-rift subsidence of the CC carbonate platform varies strongly across the south-facing but not the west-facing shelf. A sheared western CC margin differs from existing Kaoko Belt models that posit orthogonal opening with hyper-extended continental crust. Carbonate-dominated sedimentation over southwest CC implies palaeolatitudes ≤35° between 770 and 600 Ma.
MATHEMATICS ANXIETY AND CHOICE OF SUBJECT AMONG JUNIOR SECONDARY SCHOOL STUDENTS

Mathematics anxiety has been found to negatively impact students academic performance, and the trend is pervasive in our society. The purpose of this study was to determine whether math anxiety will predict students choice of subject. A total of one hundred and sixty-six junior secondary school students participated in the study. The Maths Anxiety Scale (MAS) was used to measure the respondents level of math anxiety. Their subject choice was indicated in the demographic section. The linear regression analysis conducted on the data revealed that math anxiety positively and statistically predicted students choice of subject. The findings and practical implications of the study are discussed.
Parenting Sense of Competence in Parents of Children With and Without Intellectual Disability

Our study aims to examine the relationship of child’s intellectual disability, parental education, employment and perceived stress with parenting sense of competence (satisfaction and self-efficacy). Three groups of parents (children without intellectual disability, children with mild intellectual disabilities, and children with moderate/severe intellectual disability) completed measures of perceived stress, parenting sense of competence and socio-demographic questions. Results show that child’s intellectual disability affects parenting satisfaction but not parenting self-efficacy. Parental employment predicted parenting satisfaction, but not parenting self-efficacy, while perceived stress predicted parenting satisfaction and self-efficacy. Results further suggest that parental employment moderates the relationship of child's disability with parenting satisfaction and perceived stress. Result suggest a need for interventions aimed at supporting parents in dealing with emotional consequences of their child’s disability.
Perceived export performance: The invisible part of the iceberg

This study offers a more fine-grained view of perceived export performance (EP) and map out the key aspects of this phenomenon from the perspective of SME managers. Particularly, we explore the differences in managers' practices and their perceptions about underlying aspects of EP, including level of analysis, type of performance, mode of assessment, criteria, time frames, and frames of references. Furthermore, we explore some of the key reasons for variations in EP assessment practices. This study adopts an inductive approach based on semistructured interviews with 20 exporting SMEs in New Zealand. We observed that firms exhibit distinctive behavior in their EP assessment depending on their type of ownership, stage of internationalization, and perceived psychic distance toward target markets. We challenge the assumption that a single, universal EP evaluation model can be used for SMEs and suggest that the appropriate conceptualization of EP should be dictated by each firm's strategic orientation.
Translation and Psychometric Testing of the Indonesian Version of the Preparedness for Caregiving Scale

Background: Although many previous studies have used the Preparedness for Caregiving Scale (PCS), it has not been translated and validated in Indonesia. Purpose: This study aimed to translate and evaluate the PCS’s psychometric adequacy among family caregiver of non-communicable disease (NCD) patients in Indonesia. Methods: The linguistic of the PCS was validated using a standard forward-backward process. The Indonesian version was approved with Content Validity Index (CVI). Then a cross-sectional survey was conducted to establish the construct validity of the PCS to measure caregiver preparedness. A purposive sampling approach was used to recruit 40 consenting family caregivers of NCD patients. The PCS sum score was correlated with each item using Pearson product-moment. The internal consistency of the Indonesian version of the PCS (I-PCS) was assessed using Cronbach’s alpha. Results: The Item-CVI (I-CVI) and Scale-level CVI (S-CVI) of the I-PCS were 1.00. It showed the high content validity of the I-PCS. The I-PCS revealed a Cronbach’s alpha of 0.933 for the total score. The Pearson-r was more than 0.320 indicated that the item valid. Conclusion: The I-PCS is appeared to be valid and reliable for measuring the caregiver preparedness of NCD patients in Indonesia.
Adjoint Tomography of Ambient Noise Data and Teleseismic P Waves: Methodology and Applications to Central California

Adjoint tomography has been recently applied to ambient seismic noise and teleseismic P waves separately to unveil fine‐scale lithospheric structures beyond the resolving ability of traditional ray‐based traveltime tomography. In this study, we propose an inversion scheme that alternates between frequency‐dependent traveltime inversions of ambient noise surface waves and waveform inversions of teleseismic P waves to take advantage of their complementary sensitivities to the Earth's structure. We apply our method to ambient noise empirical Green's functions from 60 virtual sources, direct P and scattered waves from 11 teleseismic events recorded by a dense linear array (∼7 km station spacing) and other regional stations (∼40 km average station spacing) in central California. To evaluate the performance of the method, we compare tomographic results from ambient noise adjoint tomography, full‐waveform inversion of teleseismic P waves, and the alternating inversion of the two data sets. Both applications to practical field data sets and synthetic checkerboard tests demonstrate the advantage of the alternating inversion over individual inversions as it combines the complementary sensitivities of the two independent data sets toward a more unified model. The three dimensional model from our alternating inversion not only shows major features of velocity anomalies and discontinuities in agreement with previous studies, but also reveals small‐scale heterogeneities which provide new constraints on the geometry of the Isabella Anomaly and mantle dynamic processes in central California. The proposed alternating inversion scheme can be applied to other regions with similar array deployments for high‐resolution lithospheric imaging.
Risk Factors for Mortality in Children with Hospital-Acquired Pneumonia in Dr. Soetomo General Hospital Surabaya

Introduction: Hospital-Acquired Pneumonia (HAP) is a nosocomial pneumonia that brings negative impacts, such as prolonged hospital stay and increased cost. Previous studies often discussed about the risk factors of HAP mortality in adult patients rather than in children. This study aimed to analyze the risk factors of mortality in children with HAP.Methods: This was a retrospective observational analytic study using cross sectional method with total sampling. A total of 73 children were enrolled in this study, consisted of inpatients at Pediatric Inpatient Room Dr. Soetomo General Hospital Surabaya who met the inclusion and exclusion criteria. Independent variables were gender, age, onset of HAP, length of stay (LOS), comorbidities, birth weight, type of breastfeeding, the use of mechanical ventilation (MV), and response to therapy. Dependent variable was mortality. The data were collected from medical records, which later were analyzed by bivariate and multivariate analysis.Results: The mortality of children with HAP was 23.3%. Bivariate analysis showed that age (p = 0.009), the use of MV (p = 0.029), and response to therapy (p = 0.036) were proven to affect mortality in children with HAP in Dr. Soetomo General Hospital Surabaya. In addition, the use of MV was the significant risk factor (p = 0.023) given by the multivariate analysis. Gender, onset of HAP, LOS, comorbidities, and type of breastfeeding were not proven to be the risk factors for mortality.Conclusion:Mortality in children with HAP in Dr. Soetomo General Hospital Surabaya was significantly affected by children’s age, the use of MV, and response to therapy. This information might be used as early signs and treatment strategies for children with HAP which lead to the decrease of hospital mortality.
Mining Industry Impact on Environmental Sustainability, Economic Growth, Social Interaction, and Public Health: An Application of Semi-Quantitative Mathematical Approach

The mining industry plays a significant role in economic growth and development. Coal is a viable renewable energy source with 185.175 billion deposits in Thar, which has not been deeply explored. Although coal is an energy source and contributes to economic development, it puts pressure on environmental sustainability. The current study investigates Sindh Engro coal mining’s impact on environmental sustainability and human needs and interest. The Folchi and Phillips Environmental Sustainability Mathematics models are employed to measure environmental sustainability. The research findings demonstrated that Sindh Engro coal mining is potentially unsustainable for the environment. The toxic gases (methane, carbon dioxide, sulfur, etc.) are released during operational activities. The four significant environment spheres (atmosphere, hydrosphere, biosphere, and lithosphere) are negatively influenced by Thar coal mining. The second part of the analysis results shows that human needs and interests have a positive and significant relationship except for human health and safety with Sindh Engro coal mining. Environmental pollution can be controlled by utilizing environmentally friendly coal mining operations and technologies. Plantation and ecological normalization can protect the species, flora, and fauna of the Thar Desert. The government of Pakistan and the provincial government of Sind should strictly check the adaptation of environmental standards. Furthermore, the researchers should explore the environmental issues and solutions so that coal mining becomes a cost-efficient and environmental-friendly energy source in Pakistan.
