A series of feature articles in the May issue of NEW JERSEY BUSINESS magazine reflects – on the one hand – the successes minority business owners, major corporations, legal counsel and institutions of higher education have achieved in breaking barriers and making the case for diversity – and, on the other hand, some of the associated challenges that still remain. Other feature articles examine: the small business loans market; business improvement districts; energy-efficiency/cost savings for businesses; and the efforts of Destination Marketing Organizations.  An additional special section focuses on construction trade unions.
