Potential Applications of functional Magnetic Resonance Imaging (fMRI) to Organizational Research: A Primer and Sample Study

The first purpose of this manuscript is to provide a primer for organizational researchers on both fMRI and brain physiology because few are likely to have encountered an in-depth treatment of either previously. The second purpose is to present the results of an actual fMRI study on an organizational topic (structured employment interviews) as a sample to help illustrate the potential of this type of research. Results of the sample study enhanced understanding of the brain processes behind responding to situational (SI) and behavior description (BDI) interviews, and offered several promising directions for follow-up research. To illustrate the latter, there appears to be separate region of the brain for handling complex social situations, which was activated only in the SI scans. This region could help explain the common use of the impression management tactic ingratiation in SIs. Given the emerging trend for larger universities to acquire fMRI equipment for research purposes, this type of research may be more viable then ever for organizational researchers

Canagliflozin and renal outcomes in type 2 diabetes and nephropathy

BACKGROUND Type 2 diabetes mellitus is the leading cause of kidney failure worldwide, but few effective long-term treatments are available. In cardiovascular trials of inhibitors of sodium–glucose cotransporter 2 (SGLT2), exploratory results have suggested that such drugs may improve renal outcomes in patients with type 2 diabetes. METHODS In this double-blind, randomized trial, we assigned patients with type 2 diabetes and albuminuric chronic kidney disease to receive canagliflozin, an oral SGLT2 inhibitor, at a dose of 100 mg daily or placebo. All the patients had an estimated glomerular filtration rate (GFR) of 30 to <90 ml per minute per 1.73 m2 of body-surface area and albuminuria (ratio of albumin [mg] to creatinine [g], >300 to 5000) and were treated with renin–angiotensin system blockade. The primary outcome was a composite of end-stage kidney disease (dialysis, transplantation, or a sustained estimated GFR of <15 ml per minute per 1.73 m2), a doubling of the serum creatinine level, or death from renal or cardiovascular causes. Prespecified secondary outcomes were tested hierarchically. RESULTS The trial was stopped early after a planned interim analysis on the recommendation of the data and safety monitoring committee. At that time, 4401 patients had undergone randomization, with a median follow-up of 2.62 years. The relative risk of the primary outcome was 30% lower in the canagliflozin group than in the placebo group, with event rates of 43.2 and 61.2 per 1000 patient-years, respectively (hazard ratio, 0.70; 95% confidence interval [CI], 0.59 to 0.82; P=0.00001). The relative risk of the renal-specific composite of end-stage kidney disease, a doubling of the creatinine level, or death from renal causes was lower by 34% (hazard ratio, 0.66; 95% CI, 0.53 to 0.81; P<0.001), and the relative risk of end-stage kidney disease was lower by 32% (hazard ratio, 0.68; 95% CI, 0.54 to 0.86; P=0.002). The canagliflozin group also had a lower risk of cardiovascular death, myocardial infarction, or stroke (hazard ratio, 0.80; 95% CI, 0.67 to 0.95; P=0.01) and hospitalization for heart failure (hazard ratio, 0.61; 95% CI, 0.47 to 0.80; P<0.001). There were no significant differences in rates of amputation or fracture. CONCLUSIONS In patients with type 2 diabetes and kidney disease, the risk of kidney failure and cardiovascular events was lower in the canagliflozin group than in the placebo group at a median follow-up of 2.62 years

Microcounselling Supervision: An Innovative Integrated Supervision Model

This article introduces a new integrated model of counselling supervision entitled the Microcounselling Supervision Model (MSM). This type of supervision is designed for supervisors and supervisees who favor eclecticism and work from multiple theoretical orientations. MSM successfully combines skills from various theories and supervision models by reviewing basic counselling skills, classifying those same skills and processing needed supervisory information gleaned from the interviewing session. The Counselling Interview Rating Form (CIRF), an integral instrument used in this model, is illustrated using examples from a case study.Le présent article présente un nouveau modèle de supervision intégrée du counseling nommé le Modèle de supervision en micro-counseling. Ce type de supervision est conçu pour les superviseurs et les supervisés qui préfèrent travailler de façon éclectique à partir d’orientations théoriques multiples. La MSM réussit à combiner des compétences de diverses théories et modèles de supervision en passant en revue les compétences de base en counseling, en les classant et en traitant l’information nécessaire à la supervision à partir de la séance d’entrevue. Le formulaire d’évaluation de l’entrevue de counseling [Counselling Interview Rating Form], un instrument qui fait partie intégrante de ce modèle, est illustré à l’aide d’exemples tirés d’une étude de cas
