Parental bonding and parent-child relationship among tertiary students
Parental bonding is an important predictor that gives a lot of insight into parent-child relationship. Studies have demonstrated the importance of parent child relationship for adjustment, ranging from attachment during infancy, indiscipline style during childhood and adolescence to parenting style during adulthood. This paper aims to investigate the relationship between parental bonding and parent-child relationship among tertiary level students in which gender and cultural effects were also taken into consideration. A survey with two valid inventories?Parental Bonding Inventory (PBI) and Parent-Child Relationship Survey (PCRS) was carried out on 160 tertiary level students from Selangor. Results indicate that stronger parental bonding promotes better parent-child relationship. Besides, females were found to have better parental bonding as well as parent-child relationship compared to males. From a cultural aspect, there is no difference among races in terms of parental bonding and parent-child relationship
Repenser la gestion des espÚces végétales exotiques envahissantes au site patrimonial du Mont-Royal avec le concept de nouvel écosystÚme
GĂ©nĂ©ralement, les plantes exotiques envahissantes sont perçues comme une menace pour la biodiversitĂ©. Cependant, peu de celles ayant Ă©tĂ© introduites dans lâest du Canada ont eu des effets nĂ©gatifs sur la faune et la flore indigĂšne. Certains chercheurs se questionnent donc quant Ă cette perception nĂ©gative des espĂšces vĂ©gĂ©tales exotiques envahissantes et suggĂšrent de modifier cette vision en intĂ©grant le concept de nouvel Ă©cosystĂšme (novel ecosystem). Ce dernier permet non seulement de rĂ©flĂ©chir et de repenser la place des EVEE au sein des Ă©cosystĂšmes, mais Ă©galement de redĂ©finir les objectifs entourant leur gestion pour quâils soient mieux adaptĂ©s aux contextes biophysiques et paysagers en place.
Lâobjectif principal de cet essai est donc de proposer une dĂ©marche intĂ©grant le concept de nouvel Ă©cosystĂšme dans la gestion des espĂšces vĂ©gĂ©tales exotiques envahissantes au QuĂ©bec, et plus particuliĂšrement au site patrimonial du Mont-Royal, appelĂ© communĂ©ment la montagne. Pour ce faire, plusieurs caractĂ©ristiques de lâĂ©cosystĂšme de la montagne ont Ă©tĂ© Ă©valuĂ©es Ă lâaide dâun cadre dĂ©cisionnel. Les rĂ©sultats de lâanalyse montrent que lâĂ©cosystĂšme du site patrimonial du Mont-Royal correspond Ă un nouvel Ă©cosystĂšme, car la composition du milieu diffĂšre de ce qui prĂ©valait historiquement et quâil nây a pas de possibilitĂ© que lâĂ©cosystĂšme puisse se rĂ©tablir sans intervention. En effet, les transformations du paysage en lien avec lâurbanisation et les pratiques horticoles en place ont profondĂ©ment modifiĂ© la dynamique Ă©cologique naturelle du mont Royal. De plus, certains obstacles au rĂ©tablissement dâordre Ă©conomique, social et environnemental continuent dâexercer des pressions sur le milieu, notamment lâĂ©pidĂ©mie dâagrile du frĂȘne, le dĂ©veloppement immobilier et les changements climatiques.
De ce fait, une priorisation des actions Ă mettre en place est essentielle pour assurer une gestion durable des espĂšces vĂ©gĂ©tales exotiques envahissantes. Pour ce faire, les espĂšces ayant un potentiel dâenvahissement Ă©levĂ© doivent ĂȘtre ciblĂ©es, alors que la prĂ©sence de celles comportant moins de risques de devenir nuisibles doit ĂȘtre acceptĂ©e. LâIndex of alien impact (IAI) utilisĂ© pour sĂ©lectionner les espĂšces pouvant engendrer le plus dâeffets nĂ©gatifs sur le milieu montre que les espĂšces prioritaires sont la renouĂ©e du Japon (Reynoutria japonica), le brome inerme (Bromus inermis), le dompte-venin de Russie (Vincetoxicum rossicum), le nerprun cathartique (Rhamnus cathartica) et le roseau commun (Phragmites australis subsp. australis). Les objectifs et les mĂ©thodes de contrĂŽle doivent ĂȘtre adaptĂ©s en fonction de chaque espĂšce, et doivent prendre en considĂ©ration la superficie dâenvahissement ainsi que le niveau dâimplantation de la plante sur lâensemble du site patrimonial du Mont-Royal. Des recommandations plus gĂ©nĂ©rales pour parvenir Ă une gestion optimale des espĂšces vĂ©gĂ©tales exotiques envahissantes incluent la mise en place de mĂ©thodes de prĂ©vention, lâimplantation de suivis et dâinventaires floristiques annuels et la coordination des actions entre les parties prenantes
C1q/TNF-related protein 3 (CTRP3) and 9 (CTRP9) concentrations are decreased in patients with heart failure and are associated with increased morbidity and mortality.
BACKGROUND: Biochemical marker has revolutionized the approach to the diagnosis of heart failure. However, it remains difficult to assess stability of the patient. As such, novel means of stratifying disease severity are needed. C1q/TNF-Related Protein 3 (CTRP3) and C1q/TNF-Related Protein 9 (CTRP9) are novel adipokines that contribute to energy homeostasis with additional anti-inflammatory and anti-ischemic properties. The aim of our study is to evaluate concentrations of CTRP3 and CTRP9 in patients with HFrEF (heart failure with reduced ejection fraction) and whether associated with mortality.
METHODS: Clinical data and plasma were obtained from 176 healthy controls and 168 patients with HFrEF. CTRP3 and CTRP9 levels were evaluated by enzyme-linked immunosorbent assay.
RESULTS: Both CTRP3 and CTRP9 concentrations were significantly decreased in the HFrEF group compared to the control group (pâ\u3câ0.001). Moreover, patients with higher New York Heart Association class had significantly lower CTRP3 or CTRP9 concentrations. Correlation analysis revealed that CTRP3 and CTRP9 levels were positively related with LVEF% (CTRP3, râ=â0.556, pâ\u3câ0.001; CTRP9, râ=â0.526, pâ\u3câ0.001) and negatively related with NT-proBNP levels (CTRP3, râ=â-â0.454, pâ\u3câ0.001; CTRP9, râ=â-â0.483, pâ\u3câ0.001). After a follow up for 36âmonths, after adjusted for age, LVEF and NT-proBNP, we observed that CTRP3 or CTRP9 levels below the 25th percentile was a predictor of total mortality (CTRP3,HR:1.93,95%CI1.03~3.62,Pâ=â0.042;CTRP9,HR:1.98,95%CI:1.02~3.85,Pâ=â0.044) and hospitalizations (CTRP3,HR:2.34,95% CI:1.43~3.82,Pâ=â0.001;CTRP9,HR:2.67,95%CI:1.58~4.50,Pâ\u3câ0.001).
CONCLUSIONS: CTRP3 and CTRP9 are decreased in patients with HFrEF, proportionate to disease severity, and each is associated with increased morbidity and mortality.

Testing Heteroscedasticity in Nonparametric Regression Based on Trend Analysis
We first propose in this paper a new test method for detecting heteroscedasticity of the error term in nonparametric regression. Some simulation experiments are then conducted to evaluate the performance of the proposed methodology. A real-world data set is finally analyzed to demonstrate the application of the method
Grey Game Model for Energy Conservation Strategies
A grey game model is constructed for enterprise carbon emissions reduction and government policies on energy conservation, which explains the interaction equilibrium strategies between government and enterprises with resource constraints. The MATLAB tools are used to simulate the game process, and the result shows that the optimal strategy is consistent with the operation result. Finally, macroscopic countermeasures and suggestions are proposed for government and enterprise
Exploring the âmiddle groundâ between state and market: the example of China
Studies of housing systems lying in the âmiddle groundâ between state and market are subject to three important shortcomings. First, the widely used Esping-Andersen (EA) approach assesses only a subset of the key housing outcomes and may be less helpful for describing changes in housing policy regimes. Second, there is too much emphasis on tenure transitions, and an assumed close correspondence between tenure labels and effective system functioning may not be valid. Third, due attention has not been given to the spatial dimensions in which housing systems operate, in particular when housing policies have a significant devolved or localised emphasis. Updating EAâs framework, we suggest a preliminary list of housing system indicators in order to capture the nature of the housing systems being developed and devolved. We verified the applicability of this indicator system with the case of China. This illustrates clearly the need for a more nuanced and systematic basis for categorising differences and changes in welfare and housing policies
