Abstract

Vector autoregressions (VAR) combined with Minnesota-type priors are widely used for macroeconomic forecasting. The fact that strong but sensible priors can substantially improve forecast performance implies VAR forecasts are sensitive to prior hyperparameters. But the nature of this sensitivity is seldom investigated. We develop a general method based on Automatic Differentiation to systematically compute the sensitivities of forecasts – both points and intervals – with respect to any prior hyperparameters. In a forecasting exercise using US data, we find that forecasts are relatively sensitive to the strength of shrinkage for the VAR coefficients, but they are not much affected by the prior mean of the error covariance matrix or the strength of shrinkage for the intercepts.

Abstract

Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.

Abstract

This article discusses the reasons and discourses adopted by the Hong Kong Special Administrative Region Government (Hong Kong SAR Government), with Mr Tung Chee Hwa as the Chief Executive, in preparing young people to become more mature and responsible. In the Hong Kong context this means they should be willing to fulfil community obligations and opt for consultation rather than confrontation should individual or community rights be sought. Confucianism, named after Confucius (551‐479 BCE), has been and still is a vast and complicated system of philosophies, morals, rituals, and ideas, which for well over 2,000 years has informed and inspired the thinking and practice of countless people in Chinese societies and Asian countries in all important areas, including the economy and the polity (Tu, 1998a; Berthrong & Berthrong, 2000; Yao, 2002). Put simply, the goal of Confucian life is to create a peaceful world, with its ethical emphasis placed on the cultivation of the self and the promotion of harmonious and respectful relations with other people in different spheres of human activities.

Abstract

Purpose

This paper aims to develop a parallel fast neighbor search method and communication strategy for particle-based methods with adaptive smoothing-length on distributed-memory computing systems.

Design/methodology/approach

With a multi-resolution-based hierarchical data structure, the parallel neighbor search method is developed to detect and construct ghost buffer particles, i.e. neighboring particles on remote processor nodes. To migrate ghost buffer particles among processor nodes, an undirected graph is established to characterize the sparse data communication relation and is dynamically recomposed. By the introduction of an edge coloring algorithm from graph theory, the complex sparse data exchange can be accomplished within optimized frequency. For each communication substep, only efficient nonblocking point-to-point communication is involved.

Findings

Two demonstration scenarios are considered: fluid dynamics based on smoothed-particle hydrodynamics with adaptive smoothing-length and a recently proposed physics-motivated partitioning method [Fu et al., JCP 341 (2017): 447-473]. Several new concepts are introduced to recast the partitioning method into a parallel version. A set of numerical experiments is conducted to demonstrate the performance and potential of the proposed parallel algorithms.

Originality/value

The proposed methods are simple to implement in large-scale parallel environment and can handle particle simulations with arbitrarily varying smoothing-lengths. The implemented smoothed-particle hydrodynamics solver has good parallel performance, suggesting the potential for other scientific applications.

Abstract

Purpose

Drawing on solidarity-conflict model, expectancy disconfirmation theory and bottom-up spillover theory, this study aims to explore how intergenerational conflict is linked to parents’ subjective well-being through the serial mediating effects of family intimacy and travel satisfaction, self-efficacy and travel satisfaction.

Design/methodology/approach

Based on a survey of 411 senior parents who have family travel experience, a structural equation modeling was performed to test the hypotheses.

Findings

This study demonstrated the negative impacts of intergenerational conflict on parents’ travel satisfaction and subjective well-being and further reveals two serial mediators through individual level and family level (i.e. self-efficacy → travel satisfaction; family intimacy → travel satisfaction).

Practical implications

The findings of this research generate valuable practical implications for family members and destination organizations. Adult children should consider different generations’ needs to choose tourism products, help parents reduce tension and negative emotions about unusual environments and build confidence. The destination organizations need to design family interaction projects with a sense of rituals to enhance family intimacy.

Originality/value

This study focusing on the intergenerational conflict of adult children traveling with parents, empirically examines the negative impacts of intergenerational conflict on parents’ subjective well-being, uncovers the detrimental effects of family travel; it breaks the stereotype that family travel is always full of joy, enriching research on intergenerational relationships and family travel.

目的

研究基于团结-冲突模型、期望不一致理论和自下而上溢出理论, 旨在通过家庭亲密度和旅行满意度、自我效能感和旅行满意度的链式中介效应探索代际冲突如何影响父母的主观幸福感。

设计/方法/步骤

基于411位有过家庭旅行经历的老年父母的调查数据, 运用结构方程模型检验假设。

研究结果

研究验证了代际冲突对父母旅行满意度和主观幸福感的负面影响, 并进一步从个人层面和家庭层面揭示了两个链式中介的作用(即自我效能感→ 旅行满意度; 家庭亲密→ 旅行满意度)。

独创性/价值

研究聚焦成年子女与父母一起旅行的代际冲突, 实证检验了代际冲突对父母主观幸福感的负面影响, 发现了家庭旅行中的消极面, 打破了家庭旅行总是充满欢乐的刻板印象, 丰富了代际关系和家庭旅行的研究成果。

实践意义

研究结果为家庭成员和目的地组织提供了具有价值的实践指导。成年子女在选择旅游产品时需要考虑不同的代际需求, 帮助父母减少非惯常环境中的紧张和负面情绪, 建立自信心。目的地组织可设计更具仪式感的家庭互动项目, 帮助提高家庭亲密度。

Propositus

Basado en el modelo de solidaridad-conflicto, la teoría de inconsistencia de expectativas y la teoría de desbordamiento de abajo hacia arriba, este estudio tiene como objetivo explorar cómo el conflicto intergeneracional está relacionado con el bienestar subjetivo de los padres a través de los efectos mediados de serie de la intimidad familiar y la satisfacción de viaje, la autoeficacia y la satisfacción de viaje.

Diseño/método/procedimiento

Basado en datos de encuestas de 411 padres mayores que tienen experiencia en viajes familiares, un modelo de ecuación estructural fue utilizado para probar las hipótesis.

Hallazgos

Este estudio demostró el impacto negativo del conflicto intergeneracional en la satisfacción de viaje de los padres y el bienestar subjetivo, y además reveló dos mediadores de serie a nivel individual y nivel familiar (es decir, autoeficacia →satisfacción de viaje; intimidad familiar →satisfacción de viaje).

Originalidad/valor

Este estudio se centra en el conflicto intergeneracional de los hijos adultos que viajan con sus padres, para examinar empíricamente el impacto negativo del conflicto intergeneracional en el bienestar subjetivo de los padres, revela los aspectos negativos de los viajes familiares, rompe el estereotipo de que los viajes familiares siempre están llenos de alegría, lo que enriquece el estudio de las relaciones intergeneracionales y los viajes familiares.

Implicaciones practices

Los hallazgos de este estudio proporciona valiosas implicaciones prácticas para los miembros de la familia y los organizadores de destinos. Los hijos adultos consideran las necesidades de diferentes generacionales para elegir productos de viaje, ayudar a los padres a reducir la tensión y las emociones negativas en entornos inusual y desarrollar la confianza y la. Los organizadores de destinos deben diseñar programas de interacción familiar con sentido de rituales para potenciar la intimidad familiar de los padres.

Abstract

Government is a very labour intensive enterprise. Public organisations provide services, enforce laws and regulations, solve problems, and have varied missions. Their varied missions include protection of the environment, food safety, elderly and disabled assistance, education of our children, and civil rights enforcement. All of these activities require the use of human resources. The quality of employees in the county directly relates to how well the county performs. Essential tasks of human resource managers are to find qualified employees for these government positions, as well as to promote an attractive work environment for these employees. Failure to use effective human resource management risks low productivity and a lack of commitment to the community. County managers have the challenge of meeting multiple objectives including productivity, staffing and many more.

Abstract

Purpose

Blueberry contains bioactive compounds which are beneficial to organisms, such as phenolics and flavonoids. The purpose of this paper is to evaluate the potential protective effects of blueberry extracts (BE) on H2O2-induced HepG2 cells.

Design/methodology/approach

Cell protection was evaluated via the survivals of the cell. Reactive oxygen species (ROS) level, antioxidant enzyme and malondialdehyde (MDA) were detected. Western blot was carried out to analysis protein which was related to the cell apoptosis pathway. Changes in morphology including: cell total apoptosis/necrosis and G0/G1 cycle arresting were also concomitant.

Findings

The levels of ROS and malondialdehyde (MDA) reduced after the BE treatment while the contents of superoxide dismutase, and glutathione peroxidase (GSH-Px) increased in HepG2 cells induced by H2O2. Furthermore, mechanistic studies indicated that BE regulated the activation of mitochondrial apoptosis signal-regulating (Bcl-2, Bax). Qu was used as a positive control group. All these results demonstrated that the BE have a potential against oxidative stress in vitro.

Originality/value

Few studies have focused on the bioactivities of blueberry on oxidative stress. Taken together, the results confirm that polyphenol-enriched BE have the ability to protect against oxidative stress in cells. It has a great potential as a functional food ingredient to health benefits. Furthermore, this work showed the value of using simple biological models to screen for compounds that are of interest for food and pharmacological industry.
