A threshold mixed count time series model: estimation and application
Authors: Dungey Mardi , Martin Vance L. , Tang Chrismin , Tremayne Andrew 
Published: March 2019

AbstractA new class of integer time series models is proposed to capture the dynamic transmission of count processes over time. The approach extends existing integer mixed autoregressive-moving average models (INARMA) by allowing for shifts in the dynamics of the count process through regime changes, referred to as a threshold integer autoregressive-moving average model (TINARMA). An efficient method of moments estimator is proposed, with standard errors based on subsampling, as maximum likelihood methods are infeasible for TINARMA processes. Applying the framework to global banking crises over 200 years of data, the empirical results show strong evidence of autoregressive and moving average dynamics which vary across systemic and nonsystemic regimes over time. Coherent forecast distributions are also produced with special attention given to the Great Depression and the more recent Global Financial Crisis.
Grappling with “Data Power”: Normative Nudges from Data Protection and Privacy
Authors: Lynskey Orla 
Published: March 2019

Abstract
The power exercised by technology companies is attracting the attention of policymakers, regulatory bodies and the general public. This power can be categorized in several ways, ranging from the “soft power” of technology companies to influence public policy agendas to the “market power” they may wield to exclude equally efficient competitors from the marketplace. This Article is concerned with the “data power” exercised by technology companies occupying strategic positions in the digital ecosystem. This data power is a multifaceted power that may overlap with economic (market) power but primarily entails the power to profile and the power to influence opinion formation.
While the current legal framework for data protection and privacy in the EU imposes constraints on personal data processing by technology companies, it ostensibly does so without regard to whether or not they have “data power.” This Article probes this assumption. It argues that although this legal framework does not explicitly impose additional legal responsibilities on entities with “data power,” it provides a clear normative indication to do so. The volume and variety of data and the reach of data-processing operations seem to be relevant when assessing both the extent of obligations on technology companies and the impact of data processing on individual rights. The Article suggests that this finding provides the normative foundation for the imposition of a “special responsibility” on such firms, analogous to the “special responsibility” imposed by competition law on dominant companies with market power. What such a “special responsibility” might entail in practice will be briefly outlined and relevant questions for future research will be identified.

Valenzuela, PL, Martín-Candilejo, R, Sánchez-Martínez, G, Bouzas Marins, JC, de la Villa, P, and Sillero-Quintana, M. Ischemic preconditioning and muscle force capabilities. J Strength Cond Res 35(8): 2187–2192, 2021—This study analyzed the effects of ischemic preconditioning (IPC) on muscle force capabilities. Sixteen male subjects participated in this randomized, crossover, sham-controlled study. They were assigned to either IPC (3 × 5 minutes at 220 mm Hg in both arms with 5-minute rests) or a sham intervention (SHAM) (occlusion pressure set at 10 mm Hg). Forty minutes later, their force capabilities on the bench press exercise were assessed (load-velocity relationship with light, moderate, and heavy loads [30, 50, and 70% body mass, respectively]; 1 repetition maximum [1RM]; and number of repetitions to failure in 3 sets with 60% RM). The skin temperature (Tsk) of the pectoral and biceps muscles was analyzed as a secondary endpoint by means of infrared thermography. A significant decrease in the Tsk of the pectoral and biceps muscles was observed after the intervention (p < 0.01) and before the warm-up (p < 0.05) in IPC, but not in SHAM. However, exercise resulted in a similar Tsk increase in the pectoral muscles in both conditions (p > 0.05). No significant differences (p > 0.05 for all) were observed between conditions in the mean velocity attained with light (1.11 ± 0.11 and 1.09 ± 0.14 m·s−1, respectively), moderate (0.83 ± 0.14 and 0.83 ± 0.16 m·s−1), nor heavy loads (0.56 ± 0.17 and 0.54 ± 0.16 m·s−1), in 1RM (75.0 ± 18.9 and 73.1 ± 15.0 kg for IPC and SHAM, respectively; p = 0.181), nor in the number of repetitions performed (52 ± 13 and 54 ± 16 repetitions, p = 0.492). In summary, IPC decreased Tsk locally (biceps) and remotely (pectoral). However, it did not alter muscle force capabilities nor the Tsk response to exercise.

Abstract
Weakley, J, Fernández-Valdés, B, Thomas, L, Ramirez-Lopez, C, and Jones, B. Criterion validity of force and power outputs for a commonly used flywheel resistance training device and bluetooth app. J Strength Cond Res 33(5): 1180–1184, 2019—Flywheels are a resistance training device that can increase lean body mass, strength, and power. However, because of their unique design and the inertia from the concentric portion directly relating to the force that is applied during the eccentric portion, monitoring the training stimulus can be difficult. Consequently, the aim of this study was to assess the validity of the kMeter app for quantifying force and power at a range of different isoinertial loads from a flywheel training device when compared against a criterion measure. Eleven subjects volunteered to take part in this study, with subjects completing between 5 and 35 repetitions of the harness squat with 0.05, 0.10, 0.15 kg·m−2 isoinertial load. A synchronized dual force plate and tricamera optoelectronic setup was used as the criterion measure to calculate force and power output, while the kMeter app was used as the practical measure. Very large to nearly perfect relationships were observed between the 2 measures, with trivial to moderate bias reported. In addition, typical error of the estimate (TEE) was found to be <10% at all isoinertial loads. These findings suggest that the kMeter app, when used in conjunction with the kBox flywheel device, demonstrates acceptable levels of validity. However, because of the TEE, the kMeter app may not be able to accurately detect small differences and therefore be suitable for research purposes. These findings suggest that the kMeter app is an acceptable method of monitoring flywheel resistance training. Furthermore, it is advised that practitioners use mean power rather than mean force.

Abstract
Strain SCT is an iodate-reducing bacterium isolated from marine sediment in Kanagawa Prefecture, Japan. In this study, we determined the draft genome sequence of strain SCT and compared it to complete genome sequences of other closely related bacteria, including Pseudomonas stutzeri. A phylogeny inferred from concatenation of core genes revealed that strain SCT was closely related to marine isolates of P. stutzeri. Genes present in the SCT genome but absent from the other analyzed P. stutzeri genomes comprised clusters corresponding to putative prophage regions and possible operons. They included pil genes, which encode type IV pili for natural transformation; the mer operon, which encodes resistance systems for mercury; and the pst operon, which encodes a Pi-specific transport system for phosphate uptake. We found that strain SCT had more prophage-like genes than the other P. stutzeri strains and that the majority (70%) of them were SCT strain-specific. These genes, encoded on distinct prophage regions, may have been acquired after branching from a common ancestor following independent phage transfer events. Thus, the genome sequence of Pseudomonas sp. strain SCT can provide detailed insights into its metabolic potential and the evolution of genetic elements associated with its unique phenotype.
The Communicative Theory of the Society: Socio-Technological and Law Enforcement Contexts
Authors: Przhilenskiy V. I. , Laza V. D. 
Published: March 2019

The article dwells on the causes and objectives of the emergence and evolution of the communicative theory of the society as a theory that allows not only to predict the development of the society, but also to manage social processes. Law enforcement system in general, and in criminal proceedings in particular, had been formed long before the emergence of this theory. But after the society was defined as a type of communication in the theory, the conditions for a truly scientific technologization of criminal proceedings were created: in fact, the whole theory of law was rebuilt in compliance with a new understanding of the phenomenon of sociality. Today, in the age of total digitalization of social and legal and law enforcement practices, the topic of the origins of the communicative theory of the society is actualized in a new way.The article analyzes the key elements of social and philosophical conceptualization of social processes and phenomena, compares the models of society proposed by O. Comte and K. Marx, whose works described the conditions for the presentation of the society as a reality. The author substantiates the statement that the alternative ways proposed by two theorists to explain social development as a function of “knowledge” or as a derivative of “social production” equally depend on the understanding of a person as a “set of social relations.” Particular attention is paid to the new opportunities opened up to theorists and philosophers in explaining the nature and functions of law in connection with the creation of the communicative theory of society. The article shows a fundamental difference in the understanding of law in the era preceding the development of sociology, and during the active interaction of legal theorists with the community of philosophers and sociologists. The author reconstructs a set of ontological assumptions that allow considering law as “a reproduction of the general conditions of the society existence” and make it possible to include the system of law in the system of social relations as a subsystem.

Published: March 2019

<p>Globally, Drugs and substance abuse continues to be a challenge, especially among the youth in school and out of school. It impacts negatively on the academic, social psychological and physical development among the abusers. This paper examines the effects of drugs and substance abuse on social conduct and academic performance among the students as well as the mitigating measures. It is based on a study carried out at Korogocho slums. A total of 102 students and 15 key informants were sampled. Questionnaire and interview guide were used to collect data. The study revealed that marijuana, miraa, alcohol and cigarettes are the most abused drugs by secondary school students and had eroded the core values hence affecting their social skills development and academic performance. The study concluded that slum life, peer pressure, congestion as well as poverty are the recipe to drug and substance abuse among students. The study recommends increased public awareness campaigns on dangers posed by drug and substance abuse involving media, civic education and all the stakeholders; and proper policy formulation and implementation.</p>
Airway Management of the Right Anterior Segmentectomy through Uniportal Video-Assisted Thoracoscopic Surgery (VATS) after Left Pneumonectomy by An Adapted Double-lumen Endobronchial Tube (DLT): A Case Report
Authors: Gu Yang , Duan Ruowang , Lv Xin , Song Jiong 
Published: March 2019

Abstract
Background

Lung resection after previous contralateral pneumonectomy is rare. We present a case of right anterior segmentectomy despite previous left pneumonectomy, demanding special ventilation strategy.

Case presentation

A 48-year-old woman was going to have the right anterior segmentectomy through uniportal video-assisted thoracoscopy (VATS) who had left pneumonectomy two years ago. A 32-French left-sided double-lumen endobronchial tube (DLT) was chosen and adapted. The DLT was intubated into the bronchus intermedius. And the upper lobe can be isolated from the ventilation in the middle and lower lobes when the bronchial cuff’s inflated. The perioperative period was uneventful and the pathological diagnosis was adenocarcinoma.

Conclusion

Lung cancer radical resection was discouraged after previous contralateral pneumonectomy partly due to the challenging ventilation and isolation. With this new DLT adapting and intubation technique showed in this case, the challenging ventilation and isolation that deter the promotion of the operation could be solved.

Abstract
Background
The evidence on diagnostic test accuracy (DTA) of diabetic retinopathy (DR) screening utilising photographic studies by non-ophthalmologist personnel in low and middle-income country (LMIC) settings is scarce. We aimed to assess DTA of DR screening using a nonmydriatic hand-held digital camera by trained general physicians in a non-ophthalmic setting.
Methods
This study is a validation of a screening intervention. We selected 700 people with diabetes (PwDM) > 18 years of age, not previously screened or treated for DR, presenting at a tertiary medical clinic in Sri Lanka. Two-field retinal imaging was used to capture fundus images before and after pupil dilatation, using a hand-held non-mydriatic (Visuscout 100®-Germany) digital retinal camera. The images were captured and graded by two trained, masked independent physician graders. The DTA of different levels of DR was assessed comparing physician’s grading with a retinologist’s clinical examination by mydriatic bio-microscopy, according to a locally adopted guideline.
Results
Seven hundred eligible PwDM were screened by physician graders. The mean age of participants was 60.8 years (SD ±10.08) and mean duration of DM was 9.9 years (SD ±8.09). Ungradable image proportion in non-mydriatic imaging was 43.4% (either eye-31.3%, both eyes 12.1%). This decreased to 12.8% (either eye-11.6%, both eyes-1.2%) following pupil dilatation. In comparison to detection of any level of DR, a referable level DR (moderate non-proliferative DR and levels above) showed a higher level of DTA. The sensitivity of the defined referable DR was 88.7% (95% CI 81.7-93.8%) for grader 1 (positive predictive value [PPV] 59.1%) and 92.5% (95% CI 86.4-96.5%) for grader 2 (PPV 68%), using mydriatic imaging, after including ungradable images as screen positives. The specificity was 94.9% (95% CI 93.6-96.0%) for grader 1 (negative predictive value [NPV] 99%) and 96.4% (95% CI 95.3-97.3%) for grader 2 (NPV 99.4%).
Conclusions
The Physicians grading of images from a digital hand-held non-mydriatic camera at a medical clinic, with dilatation of pupil of those who have ungradable images, provides a valid modality to identify referable level of DR. This could be a feasible alternative modality to the existing opportunistic screening to improve the access and coverage.

Published: March 2019

Abstract
The Guojiahe coalmine was studied to estimate the maximum water level in the fractured zone in the overburden of a thick seam in Linyou mining area, where extraction is fully-mechanized. Using a predictive model of the movement and deformation of the upper rock/soil layer in the overburden fracture zone, the free water level in the overburden was determined. Physical and numerical simulations were performed to study the development characteristics of water-flow in the fractured zone under different conditions, and the maximum water level in the fracture zone was determined. The maximum height of the fracture zone is 185 ∼ 193 m from the roof of the coal seam, and the relationship between it and the distance to the working face has a step-like function, revealing the controlling effects on water level of the key strata in the overburden.

Authors: Karim Mohammad Rezaul , Shar Muhammad Ali , Abdullah Syed 
Published: March 2019

Background:
Energy crisis is a vital issue worldwide and it will be increased tremendously
in future. Alternative energy sources have been sought for the betterment of the future world.
Solar energy is an alternative energy resource with plenty of opportunities. To make user- friendly
and cheaper solar cells, dye-sensitized solar cells are tried to develop in this aspect.

Objective:
Single dye is not good enough to capture a wide range of solar light. The blending of different
dyes is an alternative approach to harvest a wider range of solar lights on solar cells. Here,
N719 and IR dyes were utilized to get UV-VIS and NIR ranges of solar lights in dye-sensitized solar
cells.

Methods:
Dye-sensitized solar cells (DSSCs) were fabricated by using mixed dyes with various combinations
of N719 (dye A) and IR dyes (dye B). The mixed dyes solutions were adsorbed on titanium
dioxide (TiO2) and revealed significant light absorption & photosensitization compared with the
individual dye solutions. The DSSCs fabricated with more percentage of IR dyes exhibited the best
sensitization and broader spectrum.

Results:
The light absorption spectrum of the blended dyes solutions was confined peaks resultant of
both N719 and IR dyes. The maximum efficiencies of 7.91% and 7.77% were obtained with 70% and
80% of IR dyes, respectively.

Conclusion:
Both N719 and IR mixed dyes solar cells were fabricated successfully for the first time.
The relevant reasons behind the working of N719 and IR mixed dyes solar cells have been discussed.
It was also noted that only IR dyes sensitized cells did not function under the simulated sunlight.

Published: March 2019

Background
Currently, no medications are approved to treat core symptoms of autism spectrum disorder (ASD). One barrier to ASD medication development is the lack of validated outcome measures able to detect symptom change. Current ASD interventions are often evaluated using retrospective caregiver reports that describe general clinical presentation but often require recall of specific behaviors weeks after they occur, potentially reducing accuracy of the ratings. My JAKE, a mobile and Web-based mobile health (mHealth) app that is part of the Janssen Autism Knowledge Engine—a dynamically updated clinical research system—was designed to help caregivers of individuals with ASD to continuously log symptoms, record treatments, and track progress, to mitigate difficulties associated with retrospective reporting.

Objective
My JAKE was deployed in an exploratory, noninterventional clinical trial to evaluate its utility and acceptability to monitor clinical outcomes in ASD. Hypotheses regarding relationships among daily tracking of symptoms, behavior, and retrospective caregiver reports were tested.

Methods
Caregivers of individuals with ASD aged 6 years to adults (N=144) used the My JAKE app to make daily reports on their child’s sleep quality, affect, and other self-selected specific behaviors across the 8- to 10-week observational study. The results were compared with commonly used paper-and-pencil scales acquired over a concurrent period at regular 4-week intervals.

Results
Caregiver reporting of behaviors in real time was successfully captured by My JAKE. On average, caregivers made reports 2-3 days per week across the study period. Caregivers were positive about their use of the system, with over 50% indicating that they would like to use My JAKE to track behavior outside of a clinical trial. More positive average daily reporting of overall type of day was correlated with 4 weekly reports of lower caregiver burden made at 4-week intervals (r=–0.27, P=.006, n=88) and with ASD symptoms (r=–0.42, P<.001, n=112).

Conclusions
My JAKE reporting aligned with retrospective Web-based or paper-and-pencil scales. Use of mHealth apps, such as My JAKE, has the potential to increase the validity and accuracy of caregiver-reported outcomes and could be a useful way of identifying early changes in response to intervention. Such systems may also assist caregivers in tracking symptoms and behavior outside of a clinical trial, help with personalized goal setting, and monitoring of progress, which could collectively improve understanding of and quality of life for individuals with ASD and their families.
