Asian Ethnic Fertility In Canada: An Application Of The Minority Group Status Hypothesis

Based on the 1971 Census of Canada, the extent of fertility differentials as well as possible sources of variation in fertility behaviour of the major Asian ethnic groups--Chinese, Japanese, East Indian and other--are studied. Ethnic fertility differentials are examined in their socio-economic and historical context, based on a historical review of Asian ethnic groups in Canada. It is found that each of these ethnic groups have experienced inequality of treatment and discrimination in areas such as employment and services. Also documented are differences in socio-economic characteristics which are shown to be related to family size differences. It is indicated that Japanese are better integrated in the majority society in terms of their socio-economic characteristics. This examination suggests that the lower family sizes of characteristics. This examination suggests that the lower family sizes of Japanese women compared to the Chinese and East Indians may in fact reflect their structural assimilation in Canadian Society. Chinese tend to have larger family sizes and are low on socio-economic indicators. The East Indians are intermediate in their fertiltiy behaviour and have a young age structure.;The theoretical perspective used for explaining the differential fertility among Asian groups is the minority group status hypothesis. Since there has been no consensus regarding the validity of this hypothesis, it has been revised based on comments and criticisms that were available. The revision of the hypothesis tries to distinguish between the two explanations, one involving reduced minority fertility based on structural factors and another involving high minority fertility due to subcultural factors. The revised hypothesis also includes the introduction of new concepts such as ascribed and perceived minority status. The minority which is conscious of its minority status is referred to as the perceived minority and the one which is not conscious of its status is called an ascribed minority. The reconceptualization of the hypothesis also emphasizes the measurement of key theoretical concepts including the new concepts introduced. The revised hypothesis has been used to explain the family size differences of Chinese and Japanese in Canada. The results suggest stronger support for the minority status hypothesis among the Chinese indicating further declines in their fertility due to structural factors and similar weaker support among the Japanese is due to their perceived mobility

Real-time human action and gesture recognition using skeleton joints information towards medical applications

Des efforts importants ont été faits pour améliorer la précision de la détection des actions humaines à l’aide des articulations du squelette. Déterminer les actions dans un environnement bruyant reste une tâche difficile, car les coordonnées cartésiennes des articulations du squelette fournies par la caméra de détection à profondeur dépendent de la position de la caméra et de la position du squelette. Dans certaines applications d’interaction homme-machine, la position du squelette et la position de la caméra ne cessent de changer. La méthode proposée recommande d’utiliser des valeurs de position relatives plutôt que des valeurs de coordonnées cartésiennes réelles. Les récents progrès des réseaux de neurones à convolution (RNC) nous aident à obtenir une plus grande précision de prédiction en utilisant des entrées sous forme d’images. Pour représenter les articulations du squelette sous forme d’image, nous devons représenter les informations du squelette sous forme de matrice avec une hauteur et une largeur égale. Le nombre d’articulations du squelette fournit par certaines caméras de détection à profondeur est limité, et nous devons dépendre des valeurs de position relatives pour avoir une représentation matricielle des articulations du squelette. Avec la nouvelle représentation des articulations du squelette et le jeu de données MSR, nous pouvons obtenir des performances semblables à celles de l’état de l’art. Nous avons utilisé le décalage d’image au lieu de l’interpolation entre les images, ce qui nous aide également à obtenir des performances similaires à celle de l’état de l’art.There have been significant efforts in the direction of improving accuracy in detecting human action using skeleton joints. Recognizing human activities in a noisy environment is still challenging since the cartesian coordinate of the skeleton joints provided by depth camera depends on camera position and skeleton position. In a few of the human-computer interaction applications, skeleton position, and camera position keep changing. The proposed method recommends using relative positional values instead of actual cartesian coordinate values. Recent advancements in CNN help us to achieve higher prediction accuracy using input in image format. To represent skeleton joints in image format, we need to represent skeleton information in matrix form with equal height and width. With some depth cameras, the number of skeleton joints provided is limited, and we need to depend on relative positional values to have a matrix representation of skeleton joints. We can show the state-of-the-art prediction accuracy on MSR data with the help of the new representation of skeleton joints. We have used frames shifting instead of interpolation between frames, which helps us achieve state-of-the-art performance

A prospective study on functional outcome of uncemented total hip arthroplasty in patients with inflammatory arthropathies

Background: Although medical management has improved the outcome and may have reduced the need for surgery, total hip arthroplasty (THA) is often required to manage pain and restore function and mobility. The successful functional outcome of THA in patients with inflammatory arthropathies is essential in understanding the need for THA, and its benefits in those undergoing it. Objective of the study is to evaluate the functional outcome of total hip arthroplasty in patients suffering from inflammatory arthritis using Harris hip score (HHS) and to assess the post operative complication in these patients.Methods: In a prospective study conducted on patients with inflammatory arthritis treated with THA between a study period of January 2018 to January 2020. All the patients after assessing them clinically and radiologically were operated with uncemented THA through posterolateral approach. Functional outcomes of hip were evaluated using HHS at various intervals.Results: In this study, patients were followed up to 24 months. About 46.7% of patients were diagnosed with rheumatoid arthritis, 33.3% of patients were diagnosed with ankylosing spondylitis, 20% of patients were diagnosed with sero negative arthritis. 90% of patients had no limb length discrepancy, no other post-operative complications were noted. The final functional outcome of hip according to HHS were 13.3% of excellent, 56.7% good results and 30% of fair results.Conclusions: This study concludes that THA in patients with inflammatory arthritis with restricted activities of life had improved in short term follow up and ease of rehabilitation and return to function

Hyperphosphatemic tumoral calcinosis: a rare differential of periarticular swelling

Tumour calcinosis is a rare clinical and histopathological syndrome characterised by deposition of calcium deposits in different periarticular soft tissue regions of the body. It mainly manifest in childhood/ adolescence as a painless, firm to hard tumour like mass around the joints. Most common regions involved: Shoulder, elbow and hip. An 18 year old male patient presented to the opd with a history of pain and swelling over his left hip since 2 months. On examination, there was a diffuse tender swelling over the left greater trochanter, skin over the swelling was normal with no discharge, no dilated/ engorged veins. Range of motion of left hip was normal, no limb length discrepancies. X-ray: Showed a well define calcified mass over the greater trochanter with no osseous involvement. MRI revealed an encapsulated hypointense mass present posterior to the greater trochanter, mostly in the muscular plane. Lab findings revealed mild hyperphosphetemia. An aspirate from the swelling showed casseousmaterial. En mass removal was done and sent for biopsy. Biopsy showed features suggestive of tumoral calcinosis. Tumoral calcinosis is a distinct clinico-radiopathological entity characterised by soft tissue periarticular calcinosis which mimics a true neoplasm, associated with elevated levels of serum phosphate. It is an extremely rare condition which is seen in the adolescence and requires more studies regarding the surgical and medical management of the same

Fibroids are one of the most common benign tumours arising in women. Fibroids arising from Mullerian remnants are very rare. These fibroids often pose difficulty in diagnosis and management. Here, we report a rare case of fibroids arising from Mullerian remnants in MRKH syndrome and the treatment provided for the patient

The prospective analysis of functional outcome of osteosynthesis of extra-articular distal tibia fractures using minimally invasive percutaneous plate osteosynthesis technique

Background: Extra-articular distal tibial fractures are one of the most complicated ones to treat, specially comminuted fractures. Its subcutaneous nature and lack of adequate musculature makes it more prone for soft tissue damage and bone loss. The key to handle these troubling fractures is to skilfully preserve and reconstruct the soft tissues, early mobilisation and functional use of the extremity with the maintenance of satisfactory length and alignment of the fracture.Methods: This prospective longitudinal study involved 30 patients with extraarticular distal tibia fracture, who are admitted in Vydehi Institute of Medical Sciences and Research Centre between January 2017 to 2019. All were treated with closed reduction and internal fixation using pre-contoured anatomical distal tibia locking plate using minimally invasive percutaneous plate osteosynthesis (MIPPO) technique. Functional and radiological outcome along with associated complications are evaluated in serial follow up.Results: 30 patients with minimal follow up criteria of 6 months was evaluated with AOFAS score for functional outcome. At the end of 1 year, 21 cases (70%) of the cases had excellent results, 5 cases (16.7%) had good results, 3 cases had fair results and only 1 case had poor result.Conclusions: With the use of pre-contoured anatomical locking plates used, MIPPO technique is effective in extra articular distal tibia fractures where it not only helps in decreasing operating time but also in achieving excellent functional outcome with radiological union the fractures by preserving osseous vascularity and minimal soft tissue insult due to surgery

Toxic Effect of High Glucose on Cardiomyocytes, H9c2 Cells: Induction of Oxidative Stress and Ameliorative Effect of Trolox

Oxidative stress (OS) has been implicated in a variety of pathological conditions, including diabetes mellitus, characterized by hyperglycemia. In the present study, OS induced by hyperglycemia and the effect of trolox, a vitamin E analog, were studied in cardiomyocytes and H9c2 cells exposed to 15 to 33 mM glucose (HG) for 24 to 72 hours in Dulbecco modified Eagle medium. Cells treated wirh 24 or 33 mM glucose for 24 hours or above showed decreased viability and adenosine triphosphate (ATP) content with a concomitant increase in radicals of oxygen species, calcium (Ca2+), mitochondrial permeability transition, and oxidative markers, confirming that the cells were under stress. However, upon exposure to 15 mM glucose for 24 hours, H9c2 cells maintained homeostasis and ATP generation. Pretreatment of cells with trolox reduced HG-induced OS to control levels. Here, we report that the toxic effect of HG is highly regulated and that OS induction can be prevented with Trolox, a potential inhibitor of membrane damage

Cascade feedforward neural network and deep neural network controller on photovoltaic system with cascaded multilevel inverters: Comparison on standalone and grid integrated system

The introduction of a micro-grid-based power generation network will help to meet the demands of consumers while reducing environmental impact. Several industrialized and emerging countries allocate considerable resources to renewable energy-based power generation and invest significant sums of money in this area. This study examines the challenges involved with electricity generation through photovoltaic (PV) systems and the integration of the same with the grid to mitigate power quality issues and improve the power factor for various loading conditions. An innovative multilayer inverter for grid-connected PV systems has been developed to enhance the voltage profile and resulted in a drop in total harmonic distortion (THD). A cascade multilevel inverter (associated with a grid-integrated PV system and managed using multiple innovative artificial intelligence controllers) was developed in this research project. Various advanced intelligent controllers, such as cascade feedforward neural networks (CFFNN) and deep neural networks (DNN), have been analyzed under various operating situations and observed that the THD of voltage, current at the grid, and the load is less than 3 % as per the IEEE 519 standards along with this power factor is maintained nearly unity for the grid-connected system. The quality of power in terms of voltage, frequency, total harmonics distortion, and power factor are improved by using a novel deep neural network algorithm in a cascaded multilevel inverter and verified according to IEEE 1547 and IEEE 519 standards to determine the efficacy of the proposed system
