Framing the usefulness of eHRM in talent management: A case study of talent identification in a professional services firm
Authors: Wiblen Sharna
Published: April 2016

As talent management evolves from intuitive to evidence‐based decision‐making, the role of electronic Human Resource Management (eHRM) to gather, distribute, and analyze data becomes more critical. However, surprisingly few academic studies investigate the role of technology in talent management. Drawing on a qualitative case study of talent management in a large professional services firm, this paper critically examines how eHRM information technologies are framed as useful within talent identification discourses. The findings reveal two distinct but interrelated sets of processes employed to identify talent and suggest that the perceived usefulness and centrality of eHRM are influenced by how stakeholders shape their understanding of effective talent management.

Aminosilane‐Grafted Zirconia–Titiania–Silica Nanoparticles/Torlon Hollow Fiber Composites for CO2 Capture
Authors: Rownaghi Ali A. , Kant Amit , Li Xin , Thakkar Harshul , Hajari Amit , He Yingxin , Brennan Patrick J. , Hosseini Hooman , Koros William J. , Rezaei Fateme
Published: April 2016

In this work, the development of novel binary and ternary oxide/Torlon hollow fiber composites comprising zirconia, titania, and silica as amine supports was demonstrated. The resulting binary (Zr‐Si/PAI–HF, Ti‐Si/PAI–HF) and ternary (Zr‐Ti‐Si/PAI–HF) composites were then functionalized with monoamine‐, diamine‐, and triamine‐substituted trialkoxysilanes and were evaluated in CO2 capture. Although the introduction of both Zr and Ti improved the CO2 adsorption capacity relative to that with Si/PAI–HF sorbents, zirconia was found to have a more favorable effect on the CO2 adsorption performance than titania, as previously demonstrated for amine sorbents in the powder form. The Zr‐Ti‐Si/PAI–HF sample with an oxide content of 20 wt % was found to exhibit a relatively high CO2 capacity, that is, 1.90 mmol g−1 at atmospheric pressure under dry conditions, owing to more favorable synergy between the metal oxides and CO2. The ternary fiber sorbent showed improved sorption kinetics and long‐term stability in cyclic adsorption/desorption runs.
Short message service prompts for skills practice in Internet‐delivered cognitive behaviour therapy for chronic pain – are they feasible and effective?
Authors: Gandy M. , Fogliati V.J. , Terides M.D. , Johnston L. , Nicholson Perry K. , Newall C. , Titov N. , Dear B.F.
Published: April 2016

Background

Patients face numerous challenges adopting skills taught within pain self‐management programmes. The present study reports the acceptability and preliminary outcomes of supplementing an Internet‐delivered cognitive behavioural therapy (iCBT) course for chronic pain, the Pain Course, with brief automated short message service (SMS) prompts that encourage skills practice.

Methods

Participants were recruited from the Waitlist Control Group of a large randomized controlled trial and provided access to the Pain Course over 8 weeks, with the addition of SMS prompts. Fifteen SMS prompts were created to encourage the use of self‐management skills during the course. Participants were sent one random SMS prompt each business day. The acceptability of the SMS was assessed and clinical outcomes of participants who received prompts (n = 56) compared with a historical group who previously received the course without prompts (n = 139).

Results

SMS prompts were rated highly with 85% reporting them to be very helpful or helpful and that they would recommend them to others. Clinical improvements for those receiving SMS, at post‐treatment and 3‐month follow‐up (disability, d = 0.44; 0.58; anxiety d = 0.50; 0.51; depression, d = 0.78; 0.79 and average pain d = 0.49; 0.54), were consistent with participant who had received the course previously without SMS (ps >0.05).

Conclusions

Brief automated SMS prompts were an acceptable adjunct to iCBT for chronic pain but did not result in any additional clinical benefit. Further research is needed to systematically evaluate the potential of SMS prompts to increase skills practice and facilitate treatment outcomes.

What does this study add?

Automated short message service (SMS) messages are an acceptable means of prompting skills practice during iCBT for chronic pain.

SMS prompts did not improve clinical outcomes of an established clinician‐supported iCBT programme.
Consumers' preferences for fresh yam: a focus group study
Authors: Barlagne Carla , Cornet Denis , Blazy Jean‐Marc , Diman Jean‐Louis , Ozier‐Lafontaine Harry
Published: April 2016

In West and Central Africa and in the Caribbean, yam is one of the most important sources of carbohydrates and has a great potential to improve food security. The yam production sector is, however, now challenged by the satisfaction of evolving consumers' preferences. Since little is known about consumers' preferences regarding yams' characteristics, product quality, and the drivers of yam purchase, six focus group discussions were conducted (for a total of 31 participants). Among the purchasing criteria, price was considered more important than the others. It was followed by the external damage, the origin, and the size of the tuber. The most frequently cited consumption criteria were the taste, the texture, and color of flesh after cooking. Taste was considered more important than the other criteria. Three consumers' profiles were established reflecting heterogeneity in preferences, especially as concerns the willingness to pay for yam and consumption habits. They were designated as the Hedonistic, the Thrifty and the Flexible. Our results suggest that innovations can be implemented to sustain and stimulate the development of the yam sector in Guadeloupe. Two main development paths were identified. The first path is the valorization of the great existing diversity of yam varieties and the increase in the level of information for consumers about product attributes such as the cooking mode, the origin, and the mode of production. Building a marketing strategy based on the valorization of this diversity can help maintain and preserve yam's agro‐biodiversity and the satisfaction of rapidly evolving consumption habits. The second path is the definition of yam ideotypes that suit consumers' needs. We expect that tailoring the production to consumers' needs will have a positive impact on global food security in the Caribbean region.
Modeling a halogen dance reaction mechanism: A density functional theory study
Authors: Jones Leighton , Whitaker Benjamin J.
Published: April 2016

Since the discovery of the halogen dance (HD) reaction more than 60 years ago, numerous insights into the mechanism have been unveiled. To date however, the reaction has not been investigated from a theoretical perspective. Density functional theory (DFT) was used to model the potential energy surface linking the starting reagents to the lithiated products for each step in the mechanism using a thiophene substrate. It was found that the lithium‐halogen exchange mechanism is critical to understand the HD mechanism in detail and yielded the knowledge that SN2 transition states (TS) are favored over the four‐center type for the lithium‐bromine exchange steps. The overall driving force for the HD is thermodynamics, while the kinetic factors tightly control the reaction path through temperature. The SN2 lithium‐bromide TS are barrierless, except the second, which is the limiting step. Finally, the model for the HD is discovered to be a pseudo‐clock type, due to a highly favorable bromide catalysis step and the reformation of 2‐bromothiophene. © 2016 Wiley Periodicals, Inc.
Neutrophil and Eosinophil Granule Proteins as Potential Biomarkers of Assessing Disease Activity and Severity in Patients With Ulcerative Colitis
Authors: Li Zhiyan , Long Yan , Bai Mingjian , Li Junxia , Feng Zhenru
Published: April 2016

Background

Colonoscopy can assess disease activity and severity of ulcerative colitis (UC) accurately, but it is invasive and costly. Role of noninvasive biomarkers of intestinal inflammation in evaluation of patients with UC is not well understood. In this study, we assessed fecal eosinophil cationic protein (FECP), fecal myeloperoxidase (FMPO), and fecal calprotectin (FC) as surrogate markers of disease activity and severity in patients with UC, and then evaluated effect of the combination of these markers.

Methods

Sixty‐three UC patients and 59 cases of age‐matched controls were investigated. All patients underwent clinical, endoscopic, and histological assessment for disease activity and severity. Fecal samples were analyzed for FECP, FC, and FMPO.

Results

All three fecal biomarkers were elevated in patients compared with controls (P = 0.000). Significant differences were found between inactive UC and controls (P = 0.000). Cases with severe UC had significantly higher FECP levels than those with mild UC (p < 0.05), but there were no significant differences in FC and FMPO levels among disease severity groups. All three biomarkers showed positive correlation with Ulcerative Colitis Activity Index (UCAI). The areas under the ROC curve of FECP, FC, and FMPO were 0.939, 0.783, and 0.785, respectively. Sensitivity and specificity of fecal biomarkers in assessing disease activity were FECP—88.46%, 89.47%; FC—80.77%, 68.42%; and FMPO—84.62%, 63.16%.

Conclusions

All three fecal biomarkers could be used as surrogate markers for assessing disease activity of UC, and FECP provided superior discrimination than FMPO and FC. Moreover, FECP could distinguish between mild disease and severe disease group.
