A transactional stress theory of global work demands: A challenge, hindrance, or both?

We integrate research on global work demands (Shaffer et al., 2012) with transactional stress theory to examine both the harmful and beneficial effects of three global work demands-international travel, cognitive flexibility, and nonwork disruption-for employees engaged in global work. We propose that global work demands have indirect, and conditional, effects on burnout and work-to-family conflict (WFC), as well as thriving and work-family enrichment, through employees' appraisals that their global work is both hindering and challenging, respectively.

Pathologic Tuft Fracture in a Thumb: A Rare Presentation of Metastatic Endometrioid Ovarian Carcinoma: A Case Report and Review of the Literature.

Case: A 51-year-old woman with a medical history noteworthy for endometrioid ovarian carcinoma presented with progressive left thumb swelling in the absence of trauma or injury. Radiographs revealed a lytic lesion in the distal phalanx. Inflammatory markers and white blood-cell count were mildly elevated.

Sentinel lymph node positivity of patients with ductal carcinoma in situ or microinvasive breast cancer.

Purpose: The purpose of this study was to determine the rates of sentinel lymph node (SLN) positivity in patients with a final diagnosis of ductal carcinoma in situ (DCIS) or microinvasive breast cancer (MIC).

Methods: One hundred thirty patients underwent SLN mapping from 1998 to 2003 for DCIS or MIC.

Results: One hundred nine patients with DCIS and 21 with MIC underwent SLN mapping.

Can axillary dissection be avoided in patients with sentinel lymph node metastasis?

Background: Who should undergo a completion dissection following identification of a +sentinel lymph node (SLN) is controversial.

Methods: The records of 1,133 patients who underwent SLN mapping were reviewed. The association between patient, tumor, and treatment characteristics and the presence of +SLNs and +nonSLNs was analyzed using two-way tables of frequency counts and Pearson chi2 test.

Factors associated with involvement of four or more axillary nodes for sentinel lymph node-positive patients.

Purpose: Sentinel lymph node-positive (SLN+) patients who are unlikely to have 4 or more involved axillary nodes might be treated with less extensive regional nodal radiation. The purpose of this study was to define possible predictors of having 4 or more involved axillary nodes.

Methods And Materials: The records of 224 patients with breast cancer and 1 to 3 involved SLNs, who underwent completion axillary dissection without neoadjuvant chemotherapy or hormonal therapy were reviewed.

You can take it with you: individual differences and expatriate effectiveness.

The authors report the collaborative efforts of 2 research teams that independently investigated the effects of stable personality traits (the Big Five) and specific behavioral competencies (cultural flexibility, task and people orientations, and ethnocentrism) on key dimensions of expatriate effectiveness: psychological adjustment, assignment withdrawal cognitions, and job performance. Analyses of multiple-source and longitudinal data from 3 studies, including a diverse sample of expatriates in Hong Kong and separate samples of Korean and Japanese expatriates posted around the world, indicate several direct effects of individual differences. Further data show reliable distinctions between the traits and competencies as well as incremental prediction by either set of predictors in the presence of the others.

Improvement of motor development and postural control following intervention in children with sensorineural hearing loss and vestibular impairment.

Objective: The purpose of this study was to determine the effect of exercise intervention on the progressive motor development delay and postural control impairments in children with sensorineural hearing loss and concurrent vestibular impairment.

Methods: Twenty-one children with sensorineural hearing loss and vestibular impairment were randomly assigned to two groups (exercise and placebo) matched for age and gross motor development level. Exercise intervention consisted of compensatory training, emphasizing enhancement of visual and somatosensory function, and balance training.
