Theoretical basis The following theoretical concepts are applicable to the case and its learning objectives: Stakeholder Power-Interest Matrix and Carroll’s Pyramid of Corporate Social Responsibility. Research methodology Information was obtained in three separate interviews with PSEG. In February 2018, an introductory phone conference was conducted with a number of senior managers within PSEG, including the Director of Development and Strategic Issues, Kate Gerlach. In April 2018, an onsite interview was conducted with Gerlach, who connected the author with Scott Jennings. A phone interview was conducted with Scott Jennings in May 2018 and follow-up communication with him was handled via e-mail. The information obtained from these interviews was supplemented by material obtained from secondary sources. None of the information in the case has been disguised. Case overview/synopsis Scott Jennings, a Vice President at PSEG, the diversified New Jersey-based energy company, was the project leader for a large commercial wind farm that was to be built off the coast. The project, Garden State Offshore Energy, a joint venture between PSEG and Deepwater Wind, an experienced developer of offshore wind projects, had been announced over six years earlier, in late 2008. In the time that had passed, the Garden State Offshore Energy project team had waited for the New Jersey Bureau of Public Utilities, which had been tasked by Governor Chris Christie to evaluate the project costs before it could authorize the actual construction of the wind turbines. Justifying the project on a cost basis proved to be difficult; despite the growing public sentiment in favor of projects that utilized renewable energy sources such as wind power, the Garden State Offshore Energy team was unable to move the project forward. Scott needed to decide whether it made sense to continue to hold regular meetings with the Garden State Offshore Energy team. Scott’s colleagues suggested that Scott speak with senior management at PSEG to find out if the resources that had been dedicated to the Garden State Offshore Energy project could be shifted to other projects that might be more feasible. Complexity academic level This case is suitable for courses in Sustainability. It is appropriate to use the case in undergraduate courses to illustrate decision making in a regulated industry. Sufficient information is presented in the case to debate both sides of the offshore wind authorization issue.

Purpose This paper aims to study how corporate social responsibility (CSR) behaviors can lead to corporate membership on Fortune Magazine’s Most Admired Companies list. Design/methodology/approach Regression analysis using environmental, social and governance (ESG) statistics published by MSCI-KLD as independent variables to predict the behaviors that lead to most admired status. Findings Not surprisingly, corporate financial performance (CFP) is the largest contributor to membership on the list. However, after controlling for CFP, the analysis finds that specific social responsibility behaviors contribute to membership on the Fortune list. Practical implications This paper finds that CSR behaviors are important to a firm’s reputation as measured by Fortune’s Most Admired Companies list. Therefore, companies should continue with social responsibility activities to improve their reputation with investors. Originality/value Many articles test the effect of ESG on financial performance and the role of financial performance on stock price. This paper is unique in that it measures the impact of CSR on corporate reputation using an important financial market benchmark – the Fortune Most Admired Companies list.

Cardiac disease frequently has a degenerative effect on cardiac pump function and regional myocardial contraction. Therefore, an accurate assessment of regional wall motion is a measure of the extent and severity of the disease. We sought to further validate an intra-operative, sensor-based technology for measuring wall motion and strain by characterizing left ventricular (LV) mechanical and electrical activation patterns in patients with normal (NSF) and impaired systolic function (ISF). NSF (n = 10; ejection fraction = 62.9 ± 6.1%) and ISF (n = 18; ejection fraction = 35.1 ± 13.6%) patients underwent simultaneous electrical and motion mapping of the LV endocardium using electroanatomical mapping and navigational systems (EnSite™ NavX™ and MediGuide™, Abbott). Motion trajectories, strain profiles, and activation times were calculated over the six standard LV walls. NSF patients had significantly greater motion and systolic strains across all LV walls than ISF patients. LV walls with low-voltage areas showed less motion and systolic strain than walls with normal voltage. LV electrical dyssynchrony was significantly smaller in NSF and ISF patients with narrow-QRS complexes than ISF patients with wide-QRS complexes, but mechanical dyssynchrony was larger in all ISF patients than NSF patients. The latest mechanical activation was most often the lateral/posterior walls in NSF and wide-QRS ISF patients but varied in narrow-QRS ISF patients. This intra-operative technique can be used to characterize LV wall motion and strain in patients with impaired systolic function. This technique may be utilized clinically to provide individually tailored LV lead positioning at the region of latest mechanical activation for patients undergoing cardiac resynchronization therapy.

Aims In times of evolving cardiac resynchronization therapy, intra-procedural characterization of left ventricular (LV) mechanical activation patterns is desired but technically challenging with currently available technologies. In patients with normal systolic function, we evaluated the feasibility of characterizing LV wall motion using a novel sensor-based, real-time tracking technology. Methods and results Ten patients underwent simultaneous motion and electrical mapping of the LV endocardium during sinus rhythm using electroanatomical mapping and navigational systems (EnSite™ NavX™ and MediGuide™, SJM). Epicardial motion data were also collected simultaneously at corresponding locations from accessible coronary sinus branches. Displacements at each mapping point and times of electrical and mechanical activation were combined over each of the six standard LV wall segments. Mechanical activation timing was compared with that from electrical activation and preoperative 2D speckle tracking echocardiography (echo). MediGuide-based displacement data were further analysed to estimate LV chamber volumes that were compared with echo and magnetic resonance imaging (MRI). The lateral and septal walls exhibited the largest (12.5 [11.6–15.0] mm) and smallest (10.2 [9.0–11.3] mm) displacement, respectively. Radial displacement was significantly larger endocardially than epicardially (endo: 6.7 [5.0–9.1] mm; epi: 3.8 [2.4–5.6] mm), while longitudinal displacement was significantly larger epicardially (endo: 8.0 [5.0–10.6] mm; epi: 10.3 [7.4–13.8] mm). Most often, the anteroseptal/anterior and lateral walls showed the earliest and latest mechanical activations, respectively. 9/10 patients had concordant or adjacent wall segments of latest mechanical and electrical activation, and 6/10 patients had concordant or adjacent wall segments of latest mechanical activation as measured by MediGuide and echo. MediGuide's LV chamber volumes were significantly correlated with MRI ( R 2= 0.73, P < 0.01) and echo ( R 2= 0.75, P < 0.001). Conclusion The feasibility of mapping-guided intra-procedural characterization of LV wall motion was established. Clinical trial registration ; Unique identifier: CT01629160.

Students who become members of fraternities and sororities avail themselves of significant opportunities that enrich their college life. Faculty advisors play an important role in assisting fraternities and sororities in shaping students’ leadership, scholastic, and personal development. Given the risks such as alcohol use and hazing that continue to be associated with Greek life, faculty advisors also need to be actively involved in enforcing various policies to ensure student safety. In this paper, the authors review some of the problems that cause a liability risk to Greek life and they offer examples from their own experience as faculty advisors to two fraternities to help manage the risk.

Background Electroanatomic mapping systems track the position of electrodes in the heart. We assessed the feasibility of characterizing left ventricular (LV) performance during cardiac resynchronization therapy (CRT) implant utilizing an electroanatomic mapping system to track the motion of CRT lead electrodes, thus deriving ventricular contractility surrogates. Methods During CRT implant, atrial, right ventricular (RV), and LV leads were connected to the EnSite NavX™ mapping system (St. Jude Medical Inc., St. Paul, MN, USA). The relative displacement of electrodes was averaged over 10 cardiac cycles during RV, LV, and biventricular (BiV) pacing in DOO mode. Three contractility surrogates indicative of ventricular performance were extracted from the RV-LV distance waveform: systolic slope (SS), time to peak systolic contraction (TPSC), and fractional shortening (FS). Results In the 20 patients included, there were detectable differences in each of the three contractility surrogates responding to the different pacing configurations. Median SS varied 42%, median TPSC varied 35%, and median FS varied 19% across RV, LV, and BiV pacing interventions. The RV-LV distance waveform showed subtle sensitivity to varying pacing timing cycles when measured in a subset of patients. For all pacing configurations, RV-LV distance waveforms were stable during 2-minute recordings. Conclusions Tracking the motion of CRT pacing electrodes with a mapping system to derive contractility surrogates during implant is feasible.

Halo orthoses present a paradox. On the one hand, the nominally rigid immobilization they provide to the head aims to remove loads on the cervical spine following injury or surgery, and the devices are retightened routinely to maintain this. On the other hand, bone growth and remodeling are well known to require mechanical stressing. How are these competing needs balanced? To understand this trade-off in an effective, commercial halo orthosis, the authors quantified the response of a commercial halo orthosis to physiological loading levels, applied symmetrically about the sagittal plane. They showed for the first time that after a few cycles of loading analogous to a few steps taken by a patient, the support presented by a standard commercial halo orthosis becomes nonlinear. When analyzed through straightforward structural modeling, these data revealed that the nonlinearity permits mild head motion while severely restricting larger motion. These observations are useful because they open the possibility that halo orthosis installation could be optimized to transfer mild spinal loads that support healing while blocking pathological loads.

Oligopolistic markets are known to be associated with a high degree of price and output rigidity. This is due to mutual interdependencies among firms in the market with regard to price and production. The primary objective of this research is to use a business simulation game to observe the convergence in pricing that is part and parcel of the gamesmanship that occurs in an oligopoly market. A second objective of this research is to observe how a firms investments influence future productive potential. A third objective is to explore whether firm behavior changes after the other firms ex post decisions are revealed after the first four quarters of the simulation. Both descriptive statistics and regression analysis were used. Given the longitudinal nature of the data, random-effects specifications in all regressions were employed. Evidence of price rigidity was observed, especially within the first four periods when firms are not able to observe the other firms choices. Furthermore, investments in marketing and robotics appear to positively impact production.Confirming theory and previous literature, oligopolistic firms need to contend with the jockeying for position and the concomitant stickiness in prices. Therefore, it is of critical importance for firms to formulate appropriate strategies in order to succeed in an oligopoly setting.

Aims Pre-clinical work suggests that upper thoracic spinal cord stimulation (SCS) may have therapeutic effects in the treatment of heart failure (HF). We therefore aim to assess the safety and feasibility of SCS in HF patients. Methods and results A prospective, randomized, double-blind, crossover pilot study was conducted in symptomatic HF patients receiving optimal medical therapy. Patients were implanted with an SCS system and randomized to an SCS-ACTIVE, delivered at 90% paraesthesia threshold, or an SCS-INACTIVE phase for 3 months, followed by a 1-month washout period and crossover to the alternative phase. The safety of SCS therapy was assessed by death and cardiac events. Implantable cardioverter defibrillator (ICD) function in the presence of SCS was tested by defibrillation testing during SCS system implant and review of real-time and stored electrograms during follow-up. The efficacy of SCS therapy was assessed by changes in patient symptoms, LV function, and BNP level. Nine patients were investigated. In all cases, ICD sensing, detection, and therapy delivery were unaffected by SCS. During follow-up, one patient died and one was hospitalized for HF while in the SCS-INACTIVE phase, and two patients had HF hospitalizations during the SCS-ACTIVE phase. Symptoms were improved in the majority of patients with SCS, while markers of cardiac structure and function were, in aggregate, unchanged. Conclusion This study shows that an SCS system can be safely implanted in patients with advanced HF and that the SCS system does not interfere with ICD function.

Aims Alternative forms of cardiac resynchronization therapy (CRT), including biventricular endocardial (BV-Endo) and multisite epicardial pacing (MSP), have been developed to improve response. It is unclear which form of stimulation is optimal. We aimed to compare the acute haemodynamic response (AHR) and electrophysiological effects of BV-Endo with MSP via two separate coronary sinus (CS) leads or a single-quadripolar CS lead. Methods and results Fifteen patients with a previously implanted CRT system received a second temporary CS lead and left ventricular (LV) endocardial catheter. A pressure wire and non-contact mapping array were placed into the LV cavity to measure LVd P /d t max and perform electroanatomical mapping. Conventional CRT, BV-Endo, and MSP were then performed (MSP-1 via two epicardial leads and MSP-2 via a single-quadripolar lead). The best overall AHR was found using BV-Endo pacing with a 19.6 ± 13.6% increase in AHR at the optimal endocardial site over baseline ( P < 0.001). There was an increase in LVd P /d t max with MSP-1 and MSP-2 compared with conventional CRT, but this was not statistically significant. Biventricular endocardial pacing from the optimal site was significantly superior to conventional CRT ( P = 0.039). The AHR achieved when BV-Endo pacing was highly site specific. Within individuals, the best pacing modality varied and was affected by the underlying substrate. Left ventricular activation times did not predict the optimal haemodynamic configuration. Conclusion Biventricular endocardial pacing and not MSP was superior to conventional CRT, but was highly site specific. Within individuals, however, different methods of stimulation are optimal and may need to be tailored to the underlying substrate.

Case description Molly Madziva, who was born in Zimbabwe, was sent by her family to the USA to attend college. When she graduated in 2000 there were no jobs for her in Zimbabwe, as the economy was among the weakest in the world. While working as a software engineer at Bell Labs in New Jersey she decided that she wanted to help the people in her village of Macheke, the majority of who were farmers. Her idea would be an ambitious one. Molly called this the Macheke Sustainability Project. Molly met with various stakeholders who had an interest in the project. Following a thorough situation analysis and the formulation of a list of strategic initiatives, the major decision that she was left with was how to most effectively go about handling the implementation of the project. Her options included: a project within the Institute for Global Understanding at Monmouth University where she was enrolled as a graduate student; a non-profit business located in the USA; a non-governmental organization (NGO) located in Zimbabwe; and a private business in Zimbabwe. Each of these options had clear benefits. Molly was torn, however, as to which she should choose.

Interventricular mechanical dyssynchrony (VVMD) is a strong predictor of cardiac resynchronization therapy (CRT) response. However, no simple and reliable clinical method of measuring VVMD during CRT implant is currently available. We tested the hypothesis that the EnSite™ NavX™ system (St. Jude Medical, St. Paul, MN, USA) can be used intraoperatively to determine VVMD, thereby facilitating CRT optimization.During CRT implant, the leads in the right atrium (RA), right ventricle (RV), and left ventricle (LV) were connected to the EnSite™ NavX™ system to record the real-time 3D motion of the lead electrodes. The distances from RA to RV lead electrodes (RA-RV) and RA to LV lead electrodes (RA-LV) were computed over ten cardiac cycles during each of RV pacing and biventricular (BiV) pacing, respectively. The degree of synchrony was computed from the distance waveforms between RA-RV and RA-LV by a cross-covariance method to characterize VVMD. Septal-to-posterior wall motion delay (SPWMD) from M-mode echocardiography (echo) was measured for reference at each pacing intervention. VVMD was present in all five patients undergoing CRT implant.Four of the five patients demonstrated clear improvement in EnSite™ NavX™-derived VVMD during BiV versus RV pacing, which corresponded to the SPWMD results by echo.It is feasible to characterize VVMD and resynchronization in CRT patients with the EnSite™ NavX™ system during implant, demonstrating its potential as a tool for intraoperative CRT optimization.

Josh Brochhausen and Adam Podrat, as partners in The Resource, wrote commercial music for the ads of several companies. They were innovators in the recording studio, and their music appealed to young consumers.Josh and Adam also had become involved in producing records for hip hop artists. They undertook a project called Deaf in the Family, which was a full length album featuring artists from the hip hop underground. The record was well received among music critics from the underground press, but the project made no money because Josh and Adam did not have the financing to secure the appropriate clearances for the right to use samples from existing songs.Their problem centered on the uncertainty of financial success in producing hip hop records, which was their passion, and deciding whether to devote energy and resources toward it, and away from making commercial music, which was their livelihood.

A recently published computational modeling study of spinal cord stimulation (SCS) predicted that a multiple current source (MCS) system could generate a greater number of central points of stimulation in the dorsal column (DC) than a single current source (1 CS) system. However, the clinical relevance of this finding has not been established. The objective of this work was to compare the dermatomal zone selectivity of MCS and 1 CS systems. A finite element method (FEM) model was built with a representation of the spinal cord anatomy and a 2 × 8 paddle electrode array. Using a contact configuration with two aligned tripoles, the FEM model was used to solve for DC field potentials across incremental changes in current between the two cathodes, modeling the MCS and 1 CS systems. The activation regions within the DC were determined by coupling the FEM output to a biophysical nerve fiber model, and coverage was mapped to dermatomal zones. Results showed marginal differences in activated dermatomal zones between 1 CS and MCS systems. This indicates that a MCS system may not provide incremental therapeutic benefit as suggested in prior analysis.

Spinal cord stimulation (SCS) is an effective therapy for treating chronic pain. The St. Jude Medical PENTA(TM) paddle lead features a 4 × 5 contact array for achieving broad, selective coverage of dorsal column (DC) fibers. The objective of this work was to evaluate DC activation regions that correspond to dermatomal coverage with use of the PENTA lead in conjunction with a lateral sweep programming algorithm. We used a two-stage computational model, including a finite element method model of field potentials in the spinal cord during stimulation, coupled to a biophysical cable model of mammalian, myelinated nerve fibers to determine fiber activation within the DC. We found that across contact configurations used clinically in the sweep algorithm, the activation region shifted smoothly between left and right DC, and could achieve gapless medio-lateral coverage in dermatomal fiber tract zones. Increasing stimulation amplitude between the DC threshold and discomfort threshold led to a greater area of activation and number of dermatomal zones covered on the left and/or right DC, including L1-2 zones corresponding to dermatomes of the lower back. This work demonstrates that the flexibility in contact selection offered by the PENTA lead may enable patient-specific tailoring of SCS.

Electrical and Mechanical Mapping During CRT. Cardiac resynchronization therapy (CRT) restores synchrony in heart failure patients. However, a significant proportion of patients implanted with CRT devices do not realize any benefit from CRT. Placing a left ventricular (LV) lead at the sites of electrical or mechanical delay has been advocated to maximize response to CRT, but there is currently no technique described to measure mechanical delay in real-time. We describe a novel technique that can be used intraoperatively to assess mechanical and electrical activation of the coronary sinus for guidance of LV pacing site optimization during CRT implantation.

Spinal cord stimulation (SCS) has been shown to modulate atrial electrophysiology and confer protection against ischemia and ventricular arrhythmias in animal models.To determine whether SCS reduces the susceptibility to atrial fibrillation (AF) induced by tachypacing (TP).In 21 canines, upper thoracic SCS systems and custom cardiac pacing systems were implanted. Right atrial and left atrial effective refractory periods were measured at baseline and after 15 minutes of SCS. Following recovery in a subset of canines, pacemakers were turned on to induce AF by alternately delivering TP and searching for AF. Canines were randomized to no SCS therapy (CTL) or intermittent SCS therapy on the initiation of TP (EARLY) or after 8 weeks of TP (LATE). AF burden (percent AF relative to total sense time) and AF inducibility (percentage of TP periods resulting in AF) were monitored weekly. After 15 weeks, echocardiography and histology were performed.Effective refractory periods increased by 21 ± 14 ms (P = .001) in the left atrium and 29 ± 12 ms (P = .002) in the right atrium after acute SCS. AF burden was reduced for 11 weeks in EARLY compared with CTL (P.05) animals. AF inducibility remained lower by week 15 in EARLY compared with CTL animals (32% ± 10% vs 91% ± 6%; P.05). AF burden and inducibility were not significantly different between LATE and CTL animals. There were no structural differences among any groups.SCS prolonged atrial effective refractory periods and reduced AF burden and inducibility in a canine AF model induced by TP. These data suggest that SCS may represent a treatment option for AF.

A new restricted viewing system which uses computer generated holographic stereogram is presented.

A significant failure rate exists when it comes to organizational change. Managers understand the importance of organizational change, but many of them do not know how to execute it effectively. This study examines the reasons why the implementation of organizational change is so complicated and it suggests ways to break down the barriers to change.

This study investigates the effects of the use of coaching as a management style on supervisor effectiveness and key employee-related organizational policies. Specifically, we examine the direct effects of coaching on employee perceived supervisor effectiveness and organizational work-family balance support, as well as the impact of supervisory effectiveness on employee perceived effectiveness of organizational rewards programs. Ordinal regression was used to test the hypotheses, and data from 134 undergraduate and graduate business students enrolled in a Northeast university who indicated that they were currently employed on a full-time basis support these relationships. Results show that the degree to which employees view their supervisor as acting as a coach positively influences perceived supervisor effectiveness and organizational work-family balance support. Additionally, results support the notion that organizational work-family balance support also leads to perceived supervisor effectiveness which, in turn, positively influences employee perception regarding the effectiveness of organizational rewards programs.

Pneumocystis carinii is a well-recognized cause of pneumonia in patients with immune deficiency, and when untreated, mortality approaches 100 percent. Although rare cases suggesting spontaneous recovery (usually accompanied by resolving immune deficiency) have been reported, spontaneous resolution of P. carinii pneumonia in patients with the acquired immune deficiency syndrome (AIDS) has not been described. A patient with AIDS in whom Pneumocystis pneumonia developed and remitted without appropriate therapy is described. This case suggests that the immunologic defects of AIDS are not fixed and that fluctuations in the degree of immunocompetence may allow for clinical recovery from opportunistic infections associated with AIDS even without appropriate therapy.

We report 2 cases of traumatic amputation in which penile reconstruction was done by mobilization of the remaining erectile tissue.

A Mullerian adenosarcoma in which the sarcomatous element showed ovarian sex-cord like differentiation, occurred as a polypoid growth in the uterine cervix of a 53-year-old woman. The tumor was composed of an admixture of benign neoplastic glands and a sarcomatous stroma, the latter containing in addition to endometrial stromal sarcoma, nests of lipid-rich cells resembling ovarian sex-cord elements. This is the first report of such differentiation in Mullerian adenosarcoma. Origin from a focus of cervical endometriosis is postulated.
