Motor performance improved by exercises in cerebral ischemic rats

Physical exercise may induce neuroprotective effects against brain damage after stroke. The authors aimed to investigate the effects of various exercises on motor function, striatal angiogenesis, and infarct volume in cerebral ischemic rats. Adult male Sprague Dawley rats were subjected to middle cerebral artery occlusion and randomly assigned to 1 of the 4 groups: Rota-rod training, lower speed treadmill training, higher speed treadmill training, or no exercise control. Motor function, striatal angiogenesis, and infarct volume were evaluated before or after motor training. After training, motor function and striatal angiogenesis changed significantly in Rota-rod and higher speed treadmill training groups as compared with the control group. Improvement in motor function significantly correlated with striatal angiogenesis after motor training. Infarct volumes were significantly decreased in lower and higher speed treadmill training groups. The results indicated that both motor training procedures can be used as effective training programs in stroke rehabilitation.     

Gait speed measure: the effect of different measuring distances and the inclusion and exclusion of acceleration and deceleration

The purposes of this study were to examine the effects of different distances and the inclusion and exclusion of acceleration and deceleration distances on the measurement of self-paced and fastest gait speeds in younger and older adults. The self-paced and fastest gait speeds of younger and older adults were measured over 4-m and 10-m walkways with the acceleration and deceleration distances included and excluded in the measuring distance. The results indicated gait speeds (both self-paced and fastest) measured over different distances were comparable only if a distance for acceleration and deceleration was excluded from the measuring distance to obtain stable and comparable gait speeds. Similar results were found for younger and older groups.

ERP correlates of language-specific processing of auditory pitch feedback during self-vocalization

The present study investigated whether the neural correlates for auditory feedback control of vocal pitch can be shaped by tone language experience. Event-related potentials (P2/N1) were recorded from adult native speakers of Mandarin and Cantonese who heard their voice auditory feedback shifted in pitch by −50, −100, −200, or −500 cents when they sustained the vowel sound /u/. Cantonese speakers produced larger P2 amplitudes to −200 or −500 cents stimuli than Mandarin speakers, but this language effect failed to reach significance in the case of −50 or −100 cents. Moreover, Mandarin speakers produced shorter N1 latencies over the left hemisphere than the right hemisphere, whereas Cantonese speakers did not. These findings demonstrate that neural processing of auditory pitch feedback in vocal motor control is subject to language-dependent neural plasticity, suggesting that cortical mechanisms of auditory-vocal integration can be shaped by tone language experience.     

A randomized control trial of integrated care for families managing infant colic

This article presents a randomized clinical trial examining the effectiveness of a unique model of integrated care for the treatment of infant colic. Families seeking help for infant colic were randomized to either the family‐centered treatment (TX; n = 31) or standard pediatric care (SC; n = 31). All parents completed 3 days of Infant Behavior Diaries (Barr et al., 1998) and the Colic Symptom Checklist (Lester, 1997 ), Beck Depression Inventory (Beck & Steer, 1984 ), and Parenting Stress Index 3rd ed.‐SF (Abidin, 1995 ). TX families were seen three times by a pediatrician and a mental health clinician within 1, 2, and 6 weeks of baseline data. TX families received individualized treatment plans addressing problem areas of sleep, feeding, routine, and family mental health. SC families were seen only by their own healthcare provider. All families were visited at home by a research assistant to retrieve data at 2, 6, and 10 weeks after baseline. Family‐based treatment accelerated the rate of reduction of infant crying faster than did standard pediatric care. Infants in the TX group had more hours of sleep at 2 weeks posttreatment and spent less time feeding at 2, 6, and 10 weeks posttreatment than did SC infants. Results indicate that individualized family‐based treatment reduces infant colic more rapidly than does standard pediatric care.     

Differential recognition of pitch patterns in discrete and gliding stimuli in congenital amusia: evidence from Mandarin speakers

This study examined whether "melodic contour deafness" (insensitivity to the direction of pitch movement) in congenital amusia is associated with specific types of pitch patterns (discrete versus gliding pitches) or stimulus types (speech syllables versus complex tones). Thresholds for identification of pitch direction were obtained using discrete or gliding pitches in the syllable /ma/ or its complex tone analog, from nineteen amusics and nineteen controls, all healthy university students with Mandarin Chinese as their native language. Amusics, unlike controls, had more difficulty recognizing pitch direction in discrete than in gliding pitches, for both speech and non-speech stimuli. Also, amusic thresholds were not significantly affected by stimulus types (speech versus non-speech), whereas controls showed lower thresholds for tones than for speech. These findings help explain why amusics have greater difficulty with discrete musical pitch perception than with speech perception, in which continuously changing pitch movements are prevalent.     

Effectiveness of Consensus Information in Advertising: The Moderating Roles of Situational Factors and Individual Differences

Purpose

This study aims to investigate the influence of both individual consumer differences and the purchase decision context on the effectiveness of consensus information in advertising.

Design/Methodology/Approach

Three experiments explore the effectiveness of consensus information. In Experiment 1, gender serves as a moderator. Experiment 2 contains an examination of the susceptibility to interpersonal influence (SII) and purchase decision context as two potential moderators. Finally, Experiment 3 instead explores the need for cognitive closure (NFC) but again includes the purchase decision context as the two possible moderators.

Findings

In Experiment 1, female participants, but not male participants, generate higher purchase intentions for ads with consensus cues as opposed to those without them. With Experiment 2, this study demonstrates that the effectiveness of consensus cues increases for a group (vs. personal) purchase decision, but only for people with high susceptibility to individual influence. In Experiment 3, the effectiveness of consensus cues is relatively greater for a group (vs. personal) purchase decisions, but only for consumers with a high NFC.

Implications

Understanding what moderates the effectiveness of consensus information in advertising has the potential to help practitioners apply consensus information more effectively to improve their advertising returns.

Originality/Value

This study provides initial evidence about the impact of consensus information in advertising on purchase intentions, which is contingent on the situational context and individual differences.     

组织信任修复的有效性：兼顾违背类型与修复策略的影响

已有关于信任修复的研究主要集中在正直和／或能力违背方面,关注特定信任修复策略的修复效果。本研究以修复机制划分修复策略,考察不信任的约束策略及信任的展示策略对于正直违背和善心违背的修复效果差异。以408名企业员工为被试,通过情景模拟法操作违背类型和修复策略,结果显示：组织信任的正直违背比善心违背破坏性更大,更难修复;约束策略对善心违背的修复效果显著高于对正直违背的修复效果;对正直违背来说,展示策略相对更有效。     

中国文化下组织政治技能对个体自身的影响作用

组织政治技能是个体在组织中生存和获得职业发展的重要能力之一,也是组织行为学研究中的重要领域。研究主要从中国文化的视角,探讨组织政治技能对个体自身的影响作用。结果显示,组织政治技能与工作满意度之间存在线性关系,而非曲线关系;组织政治技能中的处世圆通和面子和谐两个维度有利于缓解工作压力,而人际敏锐可能增加个体的工作压力感;自我评价对于组织政治技能与工作压力和工作满意度之间关系的中介效应不显著;工作压力在处世圆通、人际敏锐和面子和谐三个维度与工作满意度之间起完全中介作用。这些结果表明,组织政治技能对于个体来说是非常重要的能力,可以帮助个体缓解工作压力,提高工作满意感,进而促进个体的职业发展。
