Types of Specific Learning Disability

The chapter “Specific Learning Disability and its Types” is an effort to educate the readers, specially the educators about a developmental disorder that begins by school age, although it may not be recognized until later. It involves on-going problems learning key academic skills, including reading, writing, and math. The chapter makes an attempt to bring about understanding of SLD, brief historical perspective and its classification. The chapter elaborately discusses the seven types of specific learning disability according to Learning Disabilities Association of America. The chapter centers around seven learning disabilities namely, dyslexia ,dysgraphia, dyscalculia, auditory processing disorder, language processing disorder, non-verbal learning disabilities , visual perceptual deficit; their causes and symptoms to give a holistic understanding about the disability for the teachers and parents to understand the individual differences.
A Novel Modeling Method for C4ISR Effectiveness Requirements

Effectiveness requirements for C4ISR system is difficult to capture and model, due to the fact that the effectiveness requirements may contain certain and uncertain requirements concepts. To solve the problem, the paper suggests a capability meta model which can define both functional and effectiveness features of the requirements. The UML modeling paradigm is extended by introducing fuzzy modeling constructs so as to describe fuzzy concepts of the effectiveness requirements. An Effectiveness Evaluation Function (EEF) based on Bézier curves is introduced to predict the effectiveness of systems. Compared with the existing requirements modeling approaches, the method enables an integrated analysis framework of functional and effectiveness requirements.
Quality Control and Anti-Inflammatory Activity of the Stem Bark of Chlorophora regia A. Chev. (Moraceae)

This study sought to develop a validated reverse-phase high-performance liquid chromatography method for the quality control of the stem bark ingredients and its finished products and investigate the synergistic anti-inflammatory activity of the phytochemical constituents of C. regia stem bark. Fractionation and isolation of biomarkers were carried out by column chromatography on silica gel and monitored by thin-layer chromatography. The isolated biomarkers were characterized based on their melting points and extensive analysis of their spectroscopic data (IR, 1D and 2D NMR). The chromatographic separation was investigated and developed for the analysis of the biomarkers using µBondapakTM C18 (3.9×300 mm, 5 µm) as stationary phase. The mobile phase composition of 0.1 % trifluoroacetic acid as solvent A, and methanol as solvent B with gradient elution was finally selected. The carrageenan-induced edema in a 7-day-old chick model was used to assess the anti-inflammatory activity of the stem bark extract and compared to diclofenac sodium as a reference drug. Two compounds were successfully isolated and identified, as Regiafuran A (1) and 3,5,7,4’-Tetrahydroxy-2’-methoxyflavonol (2). The compounds were employed as biomarkers in the RP-HPLC method development. The developed method was validated and was successfully used to quantify the amount of 1 and 2 in the stem bark to be 0.224% ± 0.056%w/w and 0.354% ± 0.041%w/w respectively. The crude extract showed considerable anti-inflammatory activity compared to the reference drug, diclofenac. The method demonstrated acceptable levels of accuracy, precision, specificity, and robustness hence can be successfully adopted for routine quality control and standardization of the stem bark of C. regia. The stem bark of the plant exhibited significant anti-inflammatory activity.
Integrating relational systems theory with ethical leadership: how ethical leadership relates to employee turnover intentions

PurposeAs ethical leadership has advanced as a construct, the degree to which healthy relational systems explain its effect on employee outcomes has been understudied. With this manuscript we conceptualize and test a model based on a Relational Systems approach to ethical leadership and its relationship with conflict and turnover intentions.Design/methodology/approachTwo studies were conducted to test our hypothesized first- and second-stage moderated mediation model. In Study 1, online surveys were completed by 168 working adults across two different time points. Study 2 extended Study 1 by surveying 115 working adults across three time points using the Mechanical Turk platform.FindingsThe indirect relationship between ethical leadership and turnover intentions via relationship conflict was conditional based on follower moral identity. The negative influence of ethical leadership on relationship conflict and, in turn, turnover intentions was stronger for followers who had higher moral identities. In addition, our findings suggest that leader holding behaviors strengthen the negative indirect effects of ethical leadership on turnover intentions.Originality/valueThis paper demonstrates the usefulness of a Relational Systems theoretical approach to understanding ethical leadership. Specifically, ethical leaders, through their desire and ability to help employees feel known and not alone at work, are better able to reduce relationship conflict and, in turn, reduce employees' desire to leave the organization.
RFID-enabled product-service system for automotive part and accessory manufacturing alliances

Automotive part and accessory manufacturers (APAMs) at the lower tiers of automotive vertical supply chains have been responding to major initiatives taken by leading vehicle assemblers in adopting RFID (radio frequency identification) and ubiquitous computing technologies to alleviate their manufacturing systems. RFID-enabled real-time traceability and visibility facilitate and enhance the implementation of advanced strategies such as just-in-time (JIT) lean/responsive manufacturing and mass customisation (MC). This paper reports on findings gained from a series of industrial field and pilot studies conducted within collaborating companies. Being typically small and medium sized, APAMs are faced with business and technical challenges that are summarised by the so-called ‘three high problems’, namely high cost, high risk and high level of technical skills. This research takes a more cost-effective pragmatic approach to overcome the ‘three high problems’ by sharing out the problems among APAMs while taking a longer-term, expensive and lengthy, approach to absolutely reduce the problems. The sharing approach requires the establishment of an innovative service-oriented framework, abbreviated AUTOPS, based on the Product Service Systems (PSS) business model. RFID hardware devices are innovated into gateways as hardcore products to formulate a PSS. RFID-enabled real-time services are deployed at a common platform across members of an APAMs alliance. AUTOPS facilities are shared by APAM alliance members to reduce the start-up investment costs, reduce the level of required specialist skills, speed up installation processes and streamline maintenance services, and improve the reliability of the RFID gateway services.
Nutrition in Patients with Lactose Malabsorption, Celiac Disease, and Related Disorders

Lactose malabsorption (LM), celiac disease (CD), non-celiac gluten sensitivity (NCGS), and irritable bowel syndrome (IBS) are conditions associated with food triggers, improvement after withdrawal, treatment with dietary restriction, and subsequent nutritional detriments. LM occurs when there is incomplete hydrolysis of lactose due to lactase deficiency and frequently produces abdominal symptoms; therefore, it can cause lactose intolerance (LI). A lactose-restricted diet is frequently recommended, although it can potentially lead to nutrient deficiencies. Furthermore, lactose is an essential component of fermentable oligo-, di-, and monosaccharides and polyols (FODMAPs) and is subsequently associated with intolerance to these compounds, especially in IBS. LM commonly presents in CD. Nutritional deficits are common in CD and can continue even on a gluten-free diet (GFD). Conditions triggered by gluten are known as gluten-related disorders (GRDs), including CD, wheat allergy, and NCGS. IBS can also be associated with a gluten sensitivity. A GFD is the treatment for CD, GRDs, and gluten sensitive IBS, although compliance with this restricted diet can be difficult. Strict dietary therapies can have a negative effect on quality of life. This review aims to provide an overview of the difficult nutritional elements of these disorders, which are critical for medical providers to recognize when managing these patients.
Local path planning for autonomous mobile robots by integrating modified dynamic‐window approach and improved follow the gap method

Mobile robots need to automatically generate a safe, goal‐oriented, and fast collision‐free trajectory in real‐time during the movement in an indoor/outdoor environment. A planned trajectory must be adaptable and drivable with environmental changes where various static and moving obstacles may be present. The ultimate goal of a robot is to reach the destination without hitting any obstacles, therefore, a reactive local path planning algorithm is needed. In this paper, a novel local algorithm is proposed by integrating dynamic window approach (DWA) and improved follow the gap method (IFGM) to generate a collision‐free trajectory for a mobile robot which is capable to avoid any moving obstacles presenting in the surrounding environment. In this proposed method, first, a safety distance is maintained according to the relative position of obstacles and the robot. Moreover, find a feasible gap to direct the robot toward the desired goal. Besides, the heading angle is calculated to change the direction of the robot for avoiding collision with nearby obstacles. After that, calculate the appropriate velocity for the robot. Finally, a robust, safe, and goal‐directed trajectory is generated which does not suffer from global convergence and local minima problems. The performance and effectiveness of this proposed algorithm are evaluated by experimental results.
Waste-to-Reuse Foam Glasses Produced from Soda-Lime-Silicate Glass, Cathode Ray Tube Glass, and Aluminium Dross

Aluminium dross is a hazardous industrial waste generated during aluminium production. It contains metallic oxides of aluminium and magnesium, other phases (aluminum nitride), and residues of fluxes and salts from the melting process of aluminium. Discarding this by-product is considered an environmental and economic challenge due to the high reactivity of dross with water or even air humidity. After removing the hazardous components from the as-received dross, one of the optional approaches is to incorporate the treated dross into construction materials. Dross is applied in several types of research as a secondary raw material source for alumina, clinker, cement or glass-ceramic production, but only a few papers focus on the usage of dross as a foaming agent for foams. Even fewer research are reported where dross was applied as a basic component of foam glasses. In this work, foam glasses were produced completely from waste materials: Aluminium dross, container (SLS) glass, and cathode ray tube (CRT) glass. The research holds several specificities, i.e., combining two industrial waste materials (CRT glass and dross), and adding an increased amount from the wastes. The physical and mechanical characteristics were examined with a special focus on the effect of the foam glass components on the microstructure, density, thermal conductivity, and compressive strength.
Efficient Filtering for Depth Sensors under Infrared Light Emitting Sources

Recently, infrared (IR)-based depth sensors have proliferated as consumer electronics thanks to decreased price, which led to various applications including gesture recognition in television virtual studios. However, the depth sensors fail to capture depth information correctly under strong light conditions emitting infrared light which are very common in television studios. This paper analyzes the mechanism of such interference between the depth sensors relying on certain IR frequencies and infrared light emitting sources, and provides methods to get correct depth information by applying filters. Also, it describes experiment methods and presents the results of applying multiple combinations of filters with different cut-off frequencies. Finally, it proves that the interference due to IR can be filtered out using proposed filtering method practically by experiment.
Surgical site complications in kidney transplant recipients: incidence, risk factors and outcomes in the modern era

Background: Surgical site complications (SSCs) are an important source of morbidity after kidney transplantation. We assessed the incidence, risk factors, outcomes and economic impact of SSCs in a large, diverse population of kidney transplant recipients. Methods: We conducted a single-centre, observational cohort study of adult (age ≥ 18 yr) patients who underwent kidney transplantation between Jan. 1, 2005, and Dec. 31, 2015, with a minimum of 1 year of follow-up. Cases of SSC, including infections and wound dehiscence, were determined from patient records. Inpatient and outpatient hospital costs were determined 6 and 12 months after transplantation. We used the Kaplan–Meier product-limit method to determine the cumulative probability of SSCs and other outcomes. We evaluated risk factors and clinical outcomes using Cox proportional hazard ratios. Linear regression models were used to study the effect of SSCs on graft function. Results: The incidence rate of SSCs within 30 days after transplantation was 4.19 per 100 person-months. The cumulative probability of developing an SSC within 30 days after transplantation was 4.13% (95% confidence interval [CI] 3.23%–5.28%). Increased recipient body mass index (BMI) (hazard ratio [HR] 1.07, 95% CI 1.02–1.11), longer cold ischemic time (HR 1.05, 95% CI 1.01–1.09) and transplantation in 2010–2012 versus 2005–2009 (HR 2.20, 95% CI 1.19–4.04) were risk factors for SSC development. In multivariable stepwise Cox proportional hazard models, SSC was a significant risk factor for death-censored graft failure (HR 3.08, 95% CI 1.60–5.90) and total graft failure (HR 2.09, 95% CI 1.32–3.32). Cumulative median hospital costs were $2238.46 greater for patients with an SSC than for those without. Conclusion: Increased BMI, longer cold ischemic time and the 2010–2012 transplantation period predisposed to SSCs. The development of SSCs was associated with a higher risk of graft failure. Strategies to minimize SSCs may improve outcomes after kidney transplantation and reduce costs.
Body Iron Overload is a Determining Factor in Brain Damage in Acute Ischemic Stroke

Stroke is the second largest cause of death worldwide, with a world annual mortality incidence of about 5.5 million people, and it is also the leading cause of disability worldwide with 50% of survivors being chronically disabled [1]. It is estimated that one in four people will experience a stroke in their lifetime [2]. Strokes may be classified into two general types: ischemic and haemorrhagic. Ischemic stroke is caused by a reduction or an interruption of the blood supply to a certain region of the brain due to the obstruction of a blood vessel. In contrast, haemorrhagic stroke occurs due to the rupture of a blood vessel causing bleeding in the brain or in the subarachnoid space [3]. This short communication is centered on ischemic stroke, which is the most prevalent form of stroke worldwide [1].
Effect of processing on vitamin A and some mineral contents of pumpkin (Cucurbita maxima) seed

Pumpkin (Cucurbita maxima) seeds are important food materials used by most Nigerian families due to their delicious taste, aroma and appeal. In this study, changes between chemical composition of processed and unprocessed pumpkin seeds (Cucurbita maxima) was investigated. The nutritional compositions were analyzed by standard methods. The vitamin A contents 36.83 μg/100g and 33.72 μg/100g respectively. The copper, zinc, magnesium,phosphorus and iron contents of processed seeds were; 0.063, 0.43, 47.67, 58.19 and 610.77 ppm respectively while the values for unprocessed were; 0.047, 0.41, 36.73, 58.45 and 211.19 ppm respectively with significant difference between the processed and unprocessed. The finding suggests that pumpkin seed is rich in this vitamin and minerals. If utilized efficiently. It can also ameliorate micronutrients deficiency problem in population of all age groups.
Anterior Cruciate Ligament Reconstruction Recovery and Rehabilitation

Background: The success of anterior cruciate ligament (ACL) reconstruction is influenced by effective rehabilitation. Previously published, comprehensive systematic reviews evaluating rehabilitation after ACL reconstruction have studied Level-I and II evidence published through 2012. Interval studies continue to evaluate the efficacy of various rehabilitative modalities. Methods: A total of 824 articles from 2012 to 2020 were identified using multiple search engines. Fifty Level-I or II studies met inclusion criteria and were evaluated using the Consolidated Standards of Reporting Trials (CONSORT) criteria and National Institutes of Health (NIH) Study Quality Assessment Tools. Results: Accelerated rehabilitation can be effective for patients with semitendinosus-gracilis grafts. Blood flow restriction (BFR) training with high-intensity exercise is not effective for ACL reconstruction recovery. Postoperative bracing does not offer any advantages or improve limb asymmetry. Cryotherapy is an effective analgesic when used perioperatively. The early introduction of open kinetic chain exercises may improve ACL reconstruction outcomes, and high-intensity plyometric exercise is not effective. Estimated pre-injury capacity (EPIC) levels may be more accurate than the Limb Symmetry Index (LSI) when using functional test results to predict reinjury rates, and hip external rotation strength may be the most accurate predictor of the hop test performance. Nerve blocks can provide postoperative analgesia with minimal complication risk. Neuromuscular electrical stimulation is effective when used independently and in combination with rehabilitative exercises. Psychological readiness should be evaluated both objectively and subjectively before allowing patients to safely return to sport. Electromyography biofeedback may help to regain muscular function, and whole-body vibration therapy can improve postural control. Supervised rehabilitation is more effective than unsupervised rehabilitation. Conclusions: Various rehabilitative modalities following ACL reconstruction are effective in improving surgical outcomes and return-to-sport rates. Further evidence and improved study design are needed to further validate modalities including accelerated rehabilitation, BFR training, functional testing, and return-to-sport criteria. Level of Evidence: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

The Dynamics of Prestall Process in an Axial Low-Speed Compressor With Single Circumferential Casing Groove

The fact that the location of single circumferential casing groove can have a large impact on the stall margin of axial compressors has been actively investigated in recent years. However, it remains a tough challenge to numerically predict the groove performance and clarify its underlying mechanism on the difference of stall margin improvement (SMI) for different groove locations. In this paper, a single rotor, which had been proven to be a tip sensitive rotor with spike type stall inception, is tested and numerically simulated with an unsteady Reynolds averaged Navier-Stokes (URANS) solver. The test results show that the rear grooves perform better than the front grooves in this rotor. A multi-passage numerical scheme is used to capture the prestall process involving the unsteady cross-passage flow interaction. Although the calculation did not fully capture the measured trend of stall margin improvement, the numerical result did show that the front groove, which is the closest to the leading edge, generates the worst stall margin extension, and the rear groove, which is located right behind the front groove, gives the best stall margin improvement.The prestall dynamics for smooth casing and the two typical grooves are chosen for a comparative study to clarify the underlying mechanism. Three different prestall processes are found. For smooth casing, a rotating disturbance evolves into spike after the interface between tip leakage flow (TLF) and incoming main flow (MF) spills in front of the leading edge. For the front groove, the interface is prevented by the groove to move forward during the throttling process. A modal wave is captured before stall. When the rear groove is applied, the interface location as a function of flow coefficient behaves much similar to the case of smooth casing. However, there is no any rotating disturbance, neither the modes nor the spike, with this groove. The flow is symmetric until all the passages break down at the same time.Copyright © 2013 by ASME
Information Systems Development Methodologies: A Review Through a Teleology Approach

The information systems analysis and design methodologies devised at the outbreak of the third industrial revolution shaped the systems analysis disciple and have trickled down to all systems influencing most aspects of human development. To cope with the explosion of digital technology, these methodologies had to be developed rapidly, drawing from a wide range of theoretical backgrounds, based mainly on the “hard” scientific method and the “softer” systems approach. In the run-up to industry 4.0, with multiple information systems emerging, reflection on systems’ design fundamentals is important. Intended to serve human activity and well-being, information systems are anthropocentric. Their success lies in their ability to serve human goals. Information systems analysis and design methodologies play a role in this by ensuring the best match between what is sought from systems and what they deliver in terms of the systems’ underlying final cause, or “telos”. The paper investigates the teleological orientation of four founding systems analysis and design methodologies. Using the Wood-Harper and Fitzgerald taxonomy in order to identify the conceptual origins of the four methodologies under review, it categorizes and subsequently incorporates them in an extended taxonomy, assesses whether and how they are devised to cater to the incorporation of goals and explains the inferred results based on the taxonomy. The paper posits that the founding information systems analysis and design methodologies do not have a marked teleological orientation and do not dispose of techniques for adequately incorporating systems’ goals.
