The use of technology can enhance workplace efficiency, productivity, and flexibility; yet, technological tools can have negative effects on individuals' cognitive, psychological, and physical health, as well as on organizations (e.g., lowered employee satisfaction, decreased employee commitment). The use of information and communications technologies (ICT) adds to existing work stress. The authors reviewed recent literature to identify ICT trends, define key terms, and gain insights to improve awareness of ICT issues related to career development, health and wellness, and job security. The potential for inquiry as it relates to career exploration, development, and advancement is relevant to counselors and clients in today's workplace. Research is needed to examine the effects of technostress across different industries, to identify workers at greatest risk of adverse effects, to explore the impact on career decision making, to help clients develop personal coping resources, and to determine strategies for career professionals to collaborate with workplace managers.

Career services professionals are increasingly involved in decisions regarding the use of technology. This article presents a number of considerations to be explored, including the characteristics and needs of today's students, available technologies, funding requirements, and confidentiality issues. The author recommends an approach that includes strategic planning, needs analyses, training, and ongoing support. Current asynchronous and synchronous technologies are described, and examples of the use of each in the context of career services are provided. The specific technologies presented are e‐mail, discussion boards, video, podcasts, websites, Internet‐based guidance and information systems, telephone, instant messages, and virtual rooms.

ABSTRACTThe growth rates of two chlorophjte macroalgae, Codium fragile and Ulva curvata, are compared i n response to varied, but non-random, NH4+ enrichments (pulses). The species were chosen to contrast radically different morphologies. Pulse frequency and pulse duration were varied independentlj; however, a n equivalent mass of NH4+ was added in each treatment. The growth rate of Codium varied neither as a function ofpulse frequency nor duration; the growth rate of Ulva varied with pulse frequency, but not pulse duration. These data are combined with l f e form and phjsiological characters, and are discussed in the context of the 'tfunction form" hypothesis. From the evidence we argue that by virtue of its life form, Ulva is capable of utilizing transiently high NH,+ concentrations and is capable of high growth rates, attributes contributing to its role as a ruderal species. I n contrast, Codium's life form does not allow utilization of transiently high NH4+ concentrations or high growth rates, thereby contributing to its role as a persistent species.
