Ocean Wave Inversion Based on a Ku/Ka Dual-Band Airborne Interferometric Imaging Radar Altimeter

Ocean wave parameters (OWPs), including wave propagation direction (WPD), significant wave height (SWH), and main wave wavelength (MWW) can be typically retrieved using an interferometric imaging radar altimeter (InIRA). However, the inversion accuracy of ocean waves in Ku (15.8 GHz) and Ka (35.8 GHz) bands has not yet been evaluated due to the lack of field observation data. In this paper, to assess the inversion accuracy of OWPs in Ku and Ka bands, an airborne observation experiment using simultaneous Ku and Ka bands was carried out for the first time in Rizhao, Shandong Province, China. A dual-band InIRA (DInIRA) was configured with small incidence angles (4°–18°) and a Global Navigation Satellite System (GNSS) buoy; a mobile weather station was placed at the intersection of the plane routes for validation. Afterward, the WPD, SWH, and MWW were retrieved based on the imaging of sea surface height. As compared with the field in situ data, the WPD inversion results of main wind wave were found to be consistent with the measurement environmental wind direction. The SWH inversion biases, retrieved by the Ku and Ka bands, were 0.38 m and 0.27 m; the MWW inversion biases for the swells were equal to 16.75 m and 3.67 m; and the MWW inversion biases about the wind waves were 2.32 m and 0.57 m. Ultimately, it was established that the OWPs could be effectively retrieved by the DInIRA, and the inversion accuracy of the SWH and the MWW in the Ka band outperformed that in the Ku band.
Approximating by Ridge Functions

This paper surveys certain aspects of the study of ridge functions. We hope it will also encourage some readers to consider researching problems in this area. After rst explaining what ridge functions are and giving various motivations for their study, we turn to the problem of presenting algorithms for approximating by ridge functions. We then touch upon the topic of determining the degree of approximation by ridge functions , and that of recognizing functions which are linear combinations of ridge functions. x1. Introduction This short paper is an introduction to certain aspects of the study of ridge functions. After rst explaining what ridge functions are and giving various motivations for their study, we turn to the problem of presenting algorithms for approximating by ridge functions. We then touch upon the topic of determining the degree of approximation by ridge functions, and that of recognizing when we have a function which is a linear combination of ridge functions. This paper is short for the very simple reason that at present rather little is known. Our goal here is to present a partial review, to try to convince you, the reader, of the signiicance of the subject, and to encourage some of you to consider researching problems in this area. A Ridge Function, in its simplest form, is a multivariate function f : IR n ! IR of the form f(x 1 ; : : : ; x n) = g(a 1 x 1 + + a n x n) = g(a x); where g : IR ! IR and a = (a 1 ; : : : ; a n) 2 IR n nf0g. In other words, it is a multivariate function constant on the parallel hyperplanes a x = c, c 2 IR. The vector a 2 IR n nf0g is generally called the direction. We should also
What Kinesiology Research is Most Visible to the Academic World?

ABSTRACT Multidisciplinary electronic databases are increasingly relied upon to compile evidence for original research and systematic reviews; however, little is known about how these services influence the visibility of kinesiology research. Citation metrics, index coverage, and subject categories of 100 kinesiology-related journals were examined using the 2020 Journal Citation Reports™ service of Clarivate Web of Science™ (WoS). Most of the journals were assigned subject categories emphasizing biomedical and multidisciplinary sciences, rather than humanities and behavioral/social sciences by WoS. WoS journal citation data were substantially skewed and there was incomplete indexing of articles in these journals, with journal issues typically unindexed for 5–11 years and more. There were substantial differences in median citation rates across the subdisciplines and subject categories of these journals. There is bias in the WoS coverage, indexing, subject categories, and citations to research published in kinesiology journals. Multiple databases should be carefully searched to ensure scholars find and utilize the breadth and depth of evidence and knowledge published in kinesiology journals.

Out of reach: The effect of shelf height on book checkouts

Abstract As the role of print collections in academic libraries moves from monograph storage to a method for engaging users, the browsability and accessibility of print collections are becoming increasingly important. One factor that affects the ability to comfortably browse collections is the height at which the books are stored. This paper examines the relationship between the shelf level on which books are shelved and their circulation rates. Results indicate that books stored on the top level tended to circulate less than books stored on lower levels, but the effect may vary based on the subject area.
Exposed Infrastructures: Discovery, Attacks and Remediation of Insecure ICS Remote Management Devices

Geographically distributed infrastructures, such as buildings, dams, and solar power plants, are commonly maintained via Internet-connected remote management devices. Previous studies on detecting and securing industrial control systems (ICS) have overlooked these remote management devices, as they do not expose ICS-specific services like Modbus and BACnet and thus do not show up in Internet-wide scans for such services. In this paper, we implement and validate a discovery method for these devices via their Web User Interface (WebUI) and detect 890 devices in Japan alone. We also show that many of these devices are highly insecure. Many allow access to the status or even the control over industrial systems without proper authentication. Taking a closer look at three prevalent remote management devices, we discovered 13 0-day vulnerabilities, several of which were rated as medium or high severity. They have been responsibly disclosed to the manufacturers. By using honeypots that imitate these systems, we show that over time, only a small number of attackers enter these systems, but some do change critical parameters. Attackers appear to interact more with the system when more facility information is displayed on the WebUI. Finally, we notified operators of 317 vulnerable remote management devices by email and telephone. We reached 212 persons in charge of the devices and received confirmation that our method had correctly identified the device. 50% of the persons in charge of the devices stated that they mitigated or will mitigate the problem. We confirmed their actions via a followup scan for vulnerable devices and found that measures were taken for 58% of the devices when we could reach the persons in charge of the device.
Alternation between the Single and Double Jet Structures in the Southern Hemisphere Troposphere: Part I: Chaotic Wandering@@@第一部 カオス的遍歴

An alternate variation between single and double jet structures in the Southern Hemisphere (SH) troposphere is investigated observationally and numerically. First, data analyses are made for 17 winters from 1979 to 1995 using the NCEP reanalysis dataset. Empirical orthogonal functions (EOFs) of the zonal-mean flow are calculated, and a probability density function (PDF) is constructed by the two leading EOF modes. Maxima of the PDF coincide with the two regimes, i.e., the single and double jet regimes, although the latter has relatively large variations in flow patterns. A statistical test indicates marginal significance for the bimodality. Transitions between the two show no marked periodicity. A low-resolution numerical model based on the primitive equation system is constructed, and is found capable of simulating the observed alternation in the single and double jet structures. The dynamical basis of this phenomenon is sought by examining the model's behavior with respect to changes in the magnitude of the horizontal diffusion coefficient. Simulated maxima in PDFs are not so significant for the lower and more realistic values of the diffusion, but become more significant for higher values. Furthermore, it is found that the model has only one attractor corresponding to the single jet regime for sufficiently large diffusivity that makes the system more stable. Near the critical value of the diffusion parameter, the system resides for a very long time in each one of the two flow regimes, and transits irregularly between them. Therefore, it is suggested that the observed variability in the SH jet structure can be understood as chaotic wandering between two distinct flow regimes, whose existence would be clearer if the system were less turbulent.
Non-profit Brand Orientation as a Strategic Communication Approach

ABSTRACT In the context of an emerging economy, this study aims to identify the factors that shape non-profit brand orientation (NBO). It also seeks to identify the main antecedents, outcomes, and barriers that are involved in its strategy implementation. The focus of this research is non-profit organizations (NPOs) in Brazil. Qualitative exploratory research with NPOs’ employees, donors, non-donors, and partners was performed using data collected from interviews, non-participant observation, and documents. The data were analyzed using content analysis. The results reveal four themes with associated categories: NBO (cause, mission, communication, and symbols); antecedents (internal factors, external factors, and community involvement); outcomes (staff relationships, partners, reputation, and performance), and barriers (a non-commercial mindset, short-term focus, communication challenges, organizational culture, government barriers, and a lack of resources). We suggest that brand strategic communication is a key factor that enables an NPO to disseminate the organization’s mission, cause, and symbols. All these factors together reflect the NBO. An NBO model is proposed, highlighting its antecedents, outcomes, and barriers, and pointing out similarities to and differences from the previous literature based on well-developed economies. This research discuss the peculiarities of NBO strategy in an emerging country context and the central point of brand strategic communication.
A Community-Based Behavioural Parent Training Model (CiC) to Address ADHD-Related Concerns in the Voluntary Sector in Denmark: A Replication and Extension

Abstract Despite demonstrated effectiveness as a psychosocial intervention for youth diagnosed with attention-deficit/hyperactivity disorder (ADHD), behavioural parent training (BPT) remains inaccessible while disorder rates increase globally. Previously, Chacko and Scavenius found that the Caring in Chaos (CiC) BPT model leveraged the advantages of community health settings, resulting in improved child and parent outcomes, prompting a need to replicate these findings. This paper reports on the effects of the CiC BPT model on the previous waitlist, untreated sample from Chacko and Scavenius. Results confirm previous findings, demonstrating CiC BPT improves parenting behaviour, competence, stress, depressive symptoms, and child impairment.
An intervention study examining the effectiveness of loving kindness meditation in reducing depressive symptoms: Compassionate coping as a mediator?

Aim: We are interested in whether the LKM intervention has the potential to decrease depression and increase self-compassion. Self-compassionate coping was examined as a mediating variable. Methods: A sample of 57 university students underwent a pretest-posttest design. Self-compassion was measured with the Self-Compassion Scale, depression with the Patient Health Questionnaire – 9, and self-compassionate coping was assessed using the Self-Compassionate Coping Measure. Participants completed all measures at both pre and posttest. Between both measurement moments there were 12 days in which participants followed either the LKM or a control exercise daily. Repeated measures ANOVAs and a simple mediation analysis were performed. Results: Over time, both groups decreased in their depression and increased in their self-compassion scores. Assignment to the LKM condition did not result in significantly higher self-compassion scores compared to control. We found a significant effect of LKM for depressive symptoms only when controlling for successfully completed homework exercises. Self-Compassionate coping did not emerge as significant mediator in our statistical analysis. Conclusion: The results indicate a mixed picture regarding the efficacy of LKM in reducing depression and increasing self-compassion. Both conditions were possibly too similar and involved helpful elements. Further research into the antidepressant utility of LKM is warranted to understand the exact mechanisms of action.
On two conjectures of J. Wahl

Let $C$ be a Brill-Noether-Petri curve of genus $g\geq23$. We prove that $C$ lies on a polarised K3 surface (or on a limit of such), if and only if the Wahl map for $C$ is not surjective. The proof is obtained by establishing the validity of two conjectures by J. Wahl. Let $\I_C$ be the ideal sheaf of a non-hyperelliptic, genus $g$, canonical curve. The first conjecture states that, if $g\geq 8$, and if the Clifford index of $C$ is greater than 2, then $H^1(\bP^{g-1}, \I_C^2(k))=0$, for $k\geq3$. We prove this conjecture for $g\geq 11$. The second conjecture states that a Brill-Noether-Petri curve of genus $g\geq 12$ is extendable, if and only if $C$ lies on a K3 surface. We prove this conjecture for $g\geq 23$; we admit, in the statement, limits of polarised K3 surfaces.
Assessing the Effect of Work From Home on the Work-Life Balance of IT Employees

The objective of this paper is to assess the effect of work from home (WFH) on the work-life balance of IT employees. The study investigated among 200 IT employees who were in full-time employment at two popular IT parks in India – Technopark and Infopark. Regression and Multidimensional Scaling ALSCAL (Euclidean Distance Model) were used for analysing data. We considered the significance of gender influence on the work-life balance (WLB) and job satisfaction on work-from-home (WFH). The research found a significant positive effect of WFH on the WLB and a positive relationship of WFH employees with work and family. We found irrespective of gender the employees of WFH had equal job satisfaction. We noticed a concern among the WFH women employees, as they have had to struggle to balance their personal and professional lives. The findings of the study have enormous policy implications in the IT sector across the globe. This paper has provided an early step in the direction of policymaking of WFH initiatives in the IT sector across the globe. JEL: O15, J81, J28, M14
Towards Automated Auditing for Account and Session Management Flaws in Single Sign-On Deployments

Single Sign-On (SSO) is both a core and critical component of user authentication and authorization on the modern web, as it is often offered by web and mobile applications alongside credential-based authentication to facilitate the account creation and login process. However, the interplay between local account management and SSO functionality in the backend leads to flaws that enable or magnify account hijacking attacks. These flaws are not baked into the actual SSO protocols, but manifest due to the complexity of supporting separate but intermingling authentication paths. As a result, these types of flaws cannot be detected by the SSO protocol or implementation verification tools proposed in prior work. In this paper we introduce SAAT, a fully automated modular framework that assesses whether relying parties (RPs) that use Facebook as the IdP comply with secure practices and guidelines, and uncovers flaws in account and session management that stem from or are affected by the interplay of SSO and local functionality. We conduct a large-scale exploration of authentication and session practices in Facebook’s RPs, revealing a volatile ecosystem where SSO support can be suddenly dropped and 17.6% of the tested RPs exhibit non-functional SSO implementations. This highlights the need for the continuous and systematic testing of the SSO ecosystem made possible by SAAT. More critically, we find that security measures are often missing and official guidelines are routinely overlooked or misconfigured, with only 0.8% of the RPs fully enabling re-authentication which can prevent compromise from hijacked identity provider (IdP) cookies. Our study also shows that less than 2% of RPs correctly react to SSO revocation and 67% continue to allow account access even 10 days after revocation. Overall, we envision our framework as a tool for enabling and guiding widespread remediation efforts by major SSO identity providers, which were previously infeasible due to the sheer scale and inherent mutability of this ecosystem.
Digital transformation of management and organization theories: A research programme

This article draws on the groundwork by George Spencer Brown and Niklas Luhmann to outline a general framework for the digital transformation of management and organization theory. It is shown under which conditions guiding distinctions of these fields may be defined as false or true. The framework is applied to selected examples, thus demonstrating that most guiding distinctions of management and organization theory are false. The article concludes with an outlook briefly expanding on the distinction between an electrification and a digital transformation of management and organization theories.
The Physical and Kinematic Structures of Molecular Clouds

A molecular cloud model that simulates the radiative transfer of the line emissions of a molecular gas is presented, together with methods for calculating the radiative transfer and line intensities in a clumpy medium. Observations of the Orion A cloud were used to study the model. To allow for a more complete distribution of molecular matter than hitherto considered, a new parameter, the volume-filling factor, is introduced. The results indicate that in order to observe the hot core of a cloud in the optically thick CO lines in a molecular gas that is not moving in a systematic way, the volume-filling factor needs to be very small at the cloud surface and increasingly large toward the center. 21 references.
An Evaluation of Key Adoption Factors towards Using the Fog Technology

Fog technology is one of the recent improvements in cloud technology that is designed to reduce some of its drawbacks. Fog technology architecture is often widely distributed to minimize the time required for data processing and enable Internet of Things (IoT) innovations. The purpose of this paper is to evaluate the main factors that might influence the adoption of fog technology. This paper offers a combined framework that addresses fog technology adoption based on the technology adoption perspective, which has been comprehensively researched in the information systems discipline. The proposed integrated framework combines the technology acceptance model (TAM) and diffusion of innovation (DOI) theory to develop a holistic perspective on the adoption of fog technology. The factors that might affect the adoption of fog technology are analyzed from the results of an online survey in 43 different organizations across a wide range of industries. These factors are observed based on data collected from 216 participants, including professional IT staff and senior business executives. This analysis was conducted by using structural equation modeling (SEM). The research results identified nine factors with a statistically significant impact on the adoption of fog technology, and these factors included relative advantage, compatibility, awareness, cost-effectiveness, security, infrastructure, ease of use, usefulness, and location. The findings from this research offer insight to organizations looking to implement fog technology to enable IoT and tap into the digital transformation opportunities presented by this new digital economy.
