Crisis, coincidences and strategic market behaviour: the internationalization of Indonesian clothing brand-owners

Despite the fact that most Indonesian brand-owners continue to emphasize their marketing activities in the domestic market, several brand-owners have started to export clothing under their own label. This has been particularly the result of the economic crisis in the late 1990s, which affected companies serving the domestic market. Companies were trying to compensate for the loss of sales on the domestic market by redirecting their marketing activities to foreign countries. This export strategy has been driven largely by the sole aim to survive. However, in addition to these export activities, some companies have rather sophisticated, long-standing business relations to their distributors in overseas markets. This paper explores these export activities in the context of the global commodity chain framework.     

2001年昆仑山口西8.1级地震地表破裂带

2001年11月14日昆仑山口西8.1级地震是近50年来在我国大陆发生的震级最大、地表破裂最长的地震事件.地震地表破裂带全长426km,宽数米至数百米,总体走向90°～110°,具有明显的破裂分段特征,自西向东由5条次级破裂段组成.各破裂段又由若干更次级左阶或右阶斜列的破裂组成,具有自相似的分形结构特征.地震破裂带以左旋走滑为主,倾滑量很小.宏观震中区位于库赛湖东北93.0°～93.5°E一带的昆仑山南麓断层谷地内.最大地表同震左旋水平位移6.4m,最大垂直位移为4m.地表水平位移沿地震破裂带走向出现6个峰值,各峰值之间存在相对独立的衰减序列,这表明此地震具有多点破裂特征.     

可可西里——东昆仑活动构造带强震活动研究

青海昆仑山口西 8.1级地震发生在具有新生性特征的可可西里—东昆仑活动断裂带上。该断裂带在 190 0年以来的 10 0多年中经历了一个强震活动过程。在该强震活动过程中 ,地震沿整个可可西里—东昆仑活动构造带分段破裂 ,强震的破裂长度和震级之间大致满足对数线性的统计关系 ,强震活动呈现指数型时间分布的加速特征。这种强震加速活动特征可以用含多个震源体的孕震系统的强震成组活动模型给予解释。     

丽江地震序列的震源机制,发震应力场和破裂特征

丽江７．０级地震震区位于我国西南地区现代构造应力场空间分布的复杂地区，区域应力场主压应力优势方位为南南东。震区位于可能受到多种构造动力源作用的特定构造运动环境中。获得了主震和２２个ＭＬ≥４．０级余震的震源机制Ｐ波初动解，分析表明，主震发震应力场为北３°东，与震区区域应力场主压应力优势方位有一个小角度的偏差。主震的发震应力不仅有水平应力的作用，同时还有显的垂直应力的作用。在余震序列发展中震区呈现出

Dynamic nucleation process of shallow earthquake faulting in a fault zone

Two distinct phases are commonly observed at the initial part of seismograms of large shallow earthquakes: low-frequency and low-amplitude waves following the onset of a P wave ( P ₁) are interrupted by the arrival of the second impulsive phase P₂ enriched with high-frequency components. This observation suggests that a large shallow earthquake involves two qualitatively different stages of rupture at its nucleation.
We propose a theoretical model that can naturally explain the above nucleation behaviour. The model is 2-D and the deformation is assumed to be anti-plane. A key clement in our model is the assumption of a zone in which numbers of pre-existing cracks are densely distributed; this cracked zone is a model for the fault zone. Dynamic crack growth nucleated in such a zone is intensely affected by the crack interactions, which exert two conflicting effects: one tends to accelerate the crack growth, and the other tends to decelerate it. The accelerating and decelerating effects are generally ascribable to coplanar and non-coplanar crack interactions, respectively. We rigorously treat the multiple interactions among the cracks, using the boundary integral equation method (BIEM), and assume the critical stress fracture criterion for the analysis of spontaneous crack propagation.
Our analysis shows that a dynamic rupture nucleated in the cracked zone begins to grow slowly due to the relative predominance of non-coplanar interactions. This process radiates the P₁ phase. If the crack continues to grow, coalescence with adjacent coplanar cracks occurs after a short time. Then, coplanar interactions suddenly begin to prevail and crack growth is accelerated; the P₂ phase is emitted in this process. It is interpreted that the two distinct phases appear in the process of the transition from non-coplanar to coplanar interaction predominance.     

区域-时间-长度算法及其在华北中强地震中短期前兆特征研究中的应用

引入并改进了区域-时间-长度算法（region-time-length algorithm），较之原来的定义更加强调了地震破裂尺度函数对VRTL的贡献，同时保证了震中距函数、时间函数及破裂尺度函数对VRTL影响的权系数相等．华北5级以上地震的回顾性预测研究结果表明，改进的RTL算法所得到的异常大多具有短期或中短期特征. 震前VRTL变化型态可分为两类:Ⅰ类具有相对完整的变化形态，大多呈现从0开始的上升——转折下降或下降——转折上升形态；Ⅱ类变化形态不完整，一般从0开始急剧上升或下降，无明显转折，主震发生在VRTL极值附近．VRTL上升表征地震活动水平相对于背景变化率的增高，意味着地震活动增强；VRTL下降则意味着地震活动相对于背景变化率的降低，在一定程度上表征了地震活动的平静．据此给出由RTL算法进行中、短期异常识别并粗略估计发震时间的方法. 该方法Ⅰ,Ⅱ类异常3个月内发震的R值评分分别为0.6及0.3左右， 6个月内的R评分分别为0.7及0.4左右．对特征时间跨度、特征距离、震级下限等对VRTL的影响, 以及其它一些实际应用中的重要问题进行了初步讨论．      

Structural and geotechnical impacts of surface rupture on highway structures during recent earthquakes in Turkey

The most significant damage on highway bridges during the recent earthquakes in Turkey (Kocaeli and Duzce earthquakes) and Taiwan (Chi–Chi earthquake) was the result of fault ruptures traversing transportation infrastructure. This phenomenon and its consequences accentuate the need to examine surface rupture hazards and to identify those areas at risk. This understanding can help to develop remedial measures for both structural and geotechnical engineering. For that purpose, damage to highway bridges during the recent events was reviewed. The total collapse of the highway overpass in Arifiye, during the Kocaeli earthquake, was investigated. The major problems under consideration (in Arifiye) were: (i) dislodging of the bridge spans, and consequently, the total separation of the reinforced concrete girders from the piers; and (ii) the stability of a mechanically stabilized earth wall (MSEW) system under extreme loading conditions. The results of the structural and geotechnical investigations presented herein can be taken in consideration to improve transportation infrastructure against surface rupture hazards.
