从"政府企业家"到"市场企业家"——新常态下西部地区创新发展的策略转变

在中国经济高速增长的过程中,虽然各区域之间的差距始终存在,但缺乏内生动力的西部地区却并未陷入恶性循环,同样保持了较为快速的经济发展.由于市场中具备企业家精神的人才流失,长期以来,西部地区地方政府如企业家般直接干预经济,并依靠自身的企业家精神为区域经济发展引入大项目创新,实现了区域经济持续增长.然而在经济发展新常态下,这种经济发展策略由于政府可调配资源日益匮乏而逐渐失效;通过制度创新激发区域内市场中的企业家精神,从而实现大、中、小规模创新的协同发展,成为西部地区创新发展的策略选择.西部地区地方政府应科学制定发展目标,积极转变职能,通过制度创新更好地让市场发挥资源配置的决定性作用,从而有效激发出区域内的企业家精神.     

推进城镇化、降低房价与房地产去库存——对我国35个大中城市的经验分析

推进城镇化和降低房价被认为是当前我国房地产去库存的主要措施.利用2001-2013年35个大中城市的数据实证检验推进城镇化和降低房价对房地产去库存的影响,结果表明:从整体上来讲,推进城镇化和降低房价确实能够有效消化当前我国过剩的房地产库存;但也表现出明显的地区差异,东部地区推进城镇化的作用明显但降低房价的作用有限,中西部地区降低房价的作用显著而推进城镇化的作用有限;此外,提高人均收入对房地产去库存也具有积极影响,而地方财政收入越高、人口密度越大的地区房地产去库存的压力越大.因此,房地产去库存应因地制宜,要根据各城市的房地产市场情况制定切实可行的政策,实现精准调控.     

The effects of attentional focus instructions on punching velocity and impact forces among trained combat athletes

Research indicates that instructing athlete’s to focus on bodily movements (internal focus of attention [IFA]) may hinder performance, whereas instructing them to focus on the movement outcome (external focus of attention [EFA]) often enhances performance. Despite the importance of instructions in striking combat sports, limited research has examined the influence of IFA and EFA on performance in well-trained combat athletes. This study investigated the effects of different instructional cues on punching velocity (m · s^?1) and normalised impact forces (N · kg^?1) among intermediate (n = 8) and expert (n = 7) competitive boxers and kickboxers. Athletes completed three rounds of 12 maximal effort punches delivered to a punching integrator on three separate days. Day one was a familiarisation session with only control instructions provided. In the following two days athletes randomly received IFA, EFA or control instructions prior to each of the three rounds. Athletes punching with EFA were 4% faster and 5% more forceful than IFA (P < 0.05), and 2% faster and 3% more forceful than control (P < 0.05). Furthermore, experts punched 11% faster and with 13% greater force compared with intermediate athletes (P < 0.05). EFA led to a positive effect on punching performance and should be favoured over IFA and control instructions.     

The effects of localised fatigue on upper extremity jump shot kinematics and kinetics in team handball

Team handball is a popular sport worldwide that requires numerous throws to be made throughout the course of a game. Because of the upper extremity demands of repetitive throwing, it is possible that fatigue can alter the mechanics of a shot. The purpose of this study was to determine the influence of localised fatigue on jump shot kinematics and kinetics. Eleven male team handball players (23.1 ± 3.1 years; 185.1 ± 8.3 cm; 89.7 ± 12.2 kg) volunteered. An electromagnetic tracking system was used to examine the jump shot prior to and following localised fatigue. The fatiguing protocol consisted of throwing a 2.2 kg medicine ball into a rebounder until volitional fatigue. No significant kinematic or kinetic differences were observed following fatigue. Shoulder external rotation was ?74.8 ± 14.9° prior to and ?79.0 ± 14.7° following fatigue at MER. Scapula, external rotation at ball release (BR) prior to fatigue was ?2.2 ± 7.0° and ?3.2 ± 11.1° following fatigue. Scapular internal rotation, at maximum shoulder internal rotation (MIR), changed from 18.4 ± 11.2° to 20.4 ± 11.8°. Ball velocity decreased from19.8 m · s^–1 to 18.8 m · s^–1 (P = 0.12). Accuracy percentage in the pre-fatigue trials was 60.8 ± 14.1% and 52.8 ± 12.7% following fatigue (P = 0.20). While no significant changes were observed, it is possible that other fatiguing protocols that more closely represent the aerobic and throwing demands of the sport may have a greater effect on the kinematics and kinetics of the jump shot.
