Abstract

Purpose

The purpose of this paper is to investigate oil-gas slug formation in horizontal straight pipe and its associated pressure gradient, slug liquid holdup and slug frequency.

Design/methodology/approach

The abrupt change in gas/liquid velocities, which causes transition of flow patterns, was analyzed using incompressible volume of fluid method to capture the dynamic gas-liquid interface. The validity of present model and its methodology was validated using Baker’s flow regime chart for 3.15 inches diameter horizontal pipe and with existing experimental data to ensure its correctness.

Findings

The present paper proposes simplified correlations for liquid holdup and slug frequency by comparison with numerous existing models. The paper also identified correlations that can be used in operational oil and gas industry and several outlier models that may not be applicable.

Research limitations/implications

The correlation may be limited to the range of material properties used in this paper.

Practical implications

Numerically derived liquid holdup and holdup frequency agreed reasonably with the experimentally derived correlations.

Social implications

The models could be used to design pipeline and piping systems for oil and gas production.

Originality/value

The paper simulated all the seven flow regimes with superior results compared to existing methodology. New correlations derived numerically are compared to published experimental correlations to understand the difference between models.

Abstract

In this paper, we model histories of coresidence between two cohorts of urban Chinese couples, married during the Cultural Revolution and early market reform periods. Most research on coresidence pictures families cross‐sectionally, but nuclear households are a natural part of extended coresidence systems that prefer stem family arrangements. We study histories of coresidence to determine what predicts ever having coresided with the husband’s parents, comparing the predictive power of modernization theory to the impact of demographic change, the availability of household members, and the resources and needs of each generation. While married children’s needs for childcare do not propel them into coresidence, they strongly predict the likelihood of staying coresident.

Abstract

Purpose

The purpose of this paper is to investigate the paradoxical pattern in which South Korean presidents enjoy imperial power early in their term, but became fragile and impotent as their term comes to an end.

Design/methodology/approach

Based on the previous literature on Korean presidentialism, this paper introduces and critically compares several competing theories on the Korean presidency and its defects.

Findings

This paper finds that for Korean presidents, imperial governance and fragility represent two sides of the same coin, like a Janus face. These two seemingly competing descriptions of the Korean presidency are not actually contradictory.

Originality/value

This paper investigates how Korean presidents are imperial with regard to constitutional design as well as political behavior, and presents a logic of transformation from an imperial president to a fragile one, focusing on party politics and election cycles.

Abstract

Purpose

The purpose of this paper is to understand the business case for corporate social responsibility (CSR) in Thailand by focusing on the consumer-organisational relationship and test the conceptual framework of Du et al. (2007).

Design/methodology/approach

A quantitative study was conducted using a mall intercept survey of 184 Thai mobile phone service provider consumers in Bangkok, Thailand.

Findings

A CSR emphasised brand is more likely than non-CSR emphasised brands to accrue consumer CSR awareness, positive attitude to company motivations and beliefs in the CSR of that company. Although beliefs are associated with consumers’ greater identification and advocacy behaviours towards the CSR emphasised brand than the non-CSR emphasised brands, they are not associated with loyalty.

Practical implications

The paper provides potential guidance for companies to more effectively position and communicate their CSR activities to create differential advantages.

Originality/value

Findings of the study demonstrate some support for a business case for CSR in Thailand.

Abstract

After the Korean War, South Korean politics was dominated by national security concerns. Reversing Carl von Clausewitz's well-known dictum, in South Korea, “politics is the continuation of war by other means.” Until the late 1980s, politics in South Korea was far from democratic. South Korea had five direct presidential elections (1987, 1992, 1997, 2002, and 2007) and six national assembly elections (1988, 1992, 1996, 2000, 2004, and 2008) after the democratic transition of 1987. In 1992, a civilian candidate, Young Sam Kim, was elected president. Young Sam Kim (1993–1998) prosecuted and punished former generals turned presidents Doo Hwan Chun (1980–1988) and Tae Woo Roh (1988–1993) for corruption, mutiny and treason in 1995. Dae Jung Kim (1998–2003) was elected president in 1997. For the first time in South Korean political history, regime change occurred between a ruling party and an opposition party.

In this chapter, the change and continuity of civil–military relations through the fluctuating dynamics of the democratic transition and consolidation in South Korea is examined. A positive consolidation of democratic reform is one that, while securing indisputable civilian supremacy, grants the military enough institutional autonomy for the efficient pursuit of its mission. Civilian supremacy should be institutionalized not only by preventing military intervention in civilian politics but also by ensuring civilian control over the formation and implementation of national defense policy.

In sum, despite three terms of civilian presidency, civilian supremacy has not yet fully institutionalized. Although significant changes in civil-military relations did occur after the democratic transition, they were not initiated by elected leaders with the intention of establishing a firm institutional footing for civilian supremacy. South Korea's political leaders have not crafted durable regulations and institutions that will sustain civilian control over the military.

More than six decades, Korea is still divided. The most highly militarized zone in the world lies along the demilitarized zone. How to draw the line prudently between seeking national security and promoting democracy shall be the most delicate task facing all the civilian regimes to come in South Korea. That mission will remain challenging not only for civilian politicians but also for military leaders.

Abstract

How did gays in the military go from being characterized as dangerous perverts threatening to the state, to victims being persecuted by the state, to potential heroes fighting on behalf of the state? What implications does this shift have for understanding the means by which the liberal state uses law to include the previously excluded? Offering a critical account of the inclusion of gays in the military, I argue that while the lifting of the ban can be seen as an important step in a classic civil rights narrative in which the liberal state gradually accommodates the excluded, pop culture allows us also to see state and minority group interest convergence as well as divergence, revealing the costs of inclusion.

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.
