Abstract
Declines in dissolved oxygen (DO) concentrations in aquatic environments can lead to conditions of hypoxia (DO ≤ 2 mg/L), which can directly and indirectly affect aquatic organisms. Direct effects include changes in growth and mortality; indirect effects include changes in distribution, movement, and interactions with other species. For mobile species, such as the pelagic filter feeding Gulf Menhaden Brevoortia patronus, indirect effects are more prevalent than direct effects. The northern Gulf of Mexico experiences one of the largest areas of seasonal hypoxia in the world; this area overlaps spatially and temporally with the Gulf Menhaden commercial purse seine fishery, which is among the largest fisheries by weight in the United States. Harvest records from the Gulf Menhaden fishery in 2006–2009 and fine scale spatial and temporal predictions from a physical–biogeochemical model were used with spatially varying regression models to examine the effects of bottom DO concentration, spatial location, depth, week, and year on four response variables: probability of fishing, total Gulf Menhaden catch, total fishery effort, and CPUE. We found nearshore shifts in the probability of fishing as DO concentration declined, and we detected a general westward shift in all response variables. We also found increases in CPUE as DO concentration declined in the Louisiana Bight, an area that experiences chronic, severe hypoxia. The overall effects of environmental conditions on fishing response variables appeared to be moderate. Nevertheless, movement of either Gulf Menhaden or the purse seine fishery in response to environmental conditions could potentially affect the susceptibility of Gulf Menhaden to harvest and could therefore influence assessment of the stock and associated stock status indicators.

Emerging Adulthood
Authors: Arnett Jeffrey Jensen 
Published: October 2014

Abstract
This is the original book presenting the theory of emerging adulthood, which offered a new conception of development from the late teens through the twenties. The book presents emerging adulthood as a new life stage that has arisen over the past half century in developed countries. It is not merely “late adolescence,” because emerging adults are not going through puberty, are not as dependent on their parents, and are not minors under the law. Nor is it the beginning of a settled “young adulthood” in which the structure of an adult life has been built that is likely to continue for decades to come. Instead, emerging adulthood is a life stage in which explorations and instability are the norm. As they focus on their self-development, emerging adults feel in-between, on the way to adulthood but not there yet. Nevertheless, they have a high level of optimism about what the future holds for them. For this tenth anniversary edition, all the chapters have been updated, and three new ones have been added, on media uses, social class issues, and problems. The other chapters cover a wide range of topics in the lives of emerging adults, including relations with parents; love, sex, and marriage; college and the transition to work; religious beliefs and values; and how emerging adults perceive their transition to adulthood. Throughout the book, vivid interview material is combined with large-scale survey research, including a national survey of 18–29-year-olds directed by the author.
Love and Sex
Authors: Arnett Jeffrey Jensen 
Published: October 2014

Abstract
This chapter examines many aspects of love and sex in the lives of emerging adults. The period that set the stage for love and sex as emerging adults experience it today was the 1960s–1970s; dating became much less formal as distinctions in gender roles came under fire by the Women’s Movement, and a new Sexual Revolution took place, including widespread use of the birth control pill. First, there is a look at the ways emerging adults meet potential love partners. This includes a discussion of the role that ethnic background plays in love choices. Then the chapter turns to sexuality, including emerging adults’ reflections on the age at which sexual activity becomes acceptable, their use (or not) of contraception, the threat of sexually transmitted infections (STIs), and uses of pornography. Finally, there is an exploration of the experiences of emerging adults who are gay or lesbian.
How Important Is Social Class?
Authors: Arnett Jeffrey Jensen 
Published: October 2014

Abstract
Critics of the theory of emerging adulthood claim that the theory applies only to the middle- and upper-middle-class young people who go to university and have enough financial support from parents to experience personal freedom and leisure during these years, but not to the working-class and lower-class young people who have far fewer options. In this chapter this issue is first addressed by reviewing research from the national Clark poll of 18–29-year-olds, showing far more similarities than differences with respect to social class. Then, four case studies are presented of African Americans in their twenties from various social class backgrounds. The Clark poll findings and these case studies illustrate that even though there are clear and sometimes dramatic differences in life prospects depending on social class, there is enough similarity across social classes to merit the application of “emerging adulthood” to the age group as a whole.
Sustainable people management through work-life balance: a study of the Malaysian Chinese context
Authors: Au Wee Chan , Ahmed Pervaiz K. 
Published: October 2014

Purpose– The purpose of this paper is to explore the harmful effects of negative externality at both national and firm level by identifying practices that impact Malaysian Chinese ' s well-being in the form of work-life imbalance.Design/methodology/approach– This paper adopts an emic approach using phenomenological enquiry to investigate what factors influence and shape work-life balance experience of Malaysian Chinese working adults. Emic approach, which takes into account elements that are indigenous to a particular culture, is useful to explore the uniqueness of the Malaysian context. Semi-structured interviews with six Malaysian Chinese working adults were conducted to understand their experience of work-life balance in the Malaysian Chinese context.Findings– The findings highlight how contextual elements in the macro-environment (such as government legislation and policy, societal values, and practices) and the firm environment (owner and leadership values, superiors’ attitude) come together to shape the overall experience of work-life balance among Chinese Malaysians. The findings show that current work-life practices in Malaysia fall short in a number of ways, which ultimately leads to an unsustainable human resource position for Malaysian firms.Practical implications– From a practical perspective the paper highlights the need to focus on employees’ work-life balance as a means to create sustainable and productive workplaces.Originality/value– Given that the concept of work-life balance is grounded in western literature, it is important to explore the nature and relevance work-life balance in sustaining human resources in nonwestern, especially less developed business settings. Findings of this study contribute to the work-life literature by exploring the work-life balance experience in Malaysia through emic approach using a phenomenological lens. The findings identify a shortfall in sustainable people management arising through the interplay of unique negative externality multi-level contextual factors.
Analog circuit optimization on basis of control theory approach
Authors: Zemliak Alexander 
Published: October 2014

Purpose
– The purpose of this paper is to define the process of analog circuit optimization on the basis of the control theory application. This approach produces many different strategies of optimization and determines the problem of searching of the best strategy in sense of minimal computer time. The determining of the best strategy of optimization and a searching of possible structure of this strategy with a minimal computer time is a principal aim of this work.

Design/methodology/approach
– Different kinds of strategies for circuit optimization have been evaluated from the point of view of operations’ number. The generalized methodology for the optimization of analog circuit was formulated by means of the optimum control theory. The main equations for this methodology were elaborated. These equations include the special control functions that are introduced artificially. This approach generalizes the problem and generates an infinite number of different strategies of optimization. A problem of construction of the best algorithm of optimization is defined as a typical problem of the control theory. Numerical results show the possibility of application of this approach for optimization of electronic circuits and demonstrate the efficiency and perspective of the proposed methodology.

Findings
– Examples show that the better optimization strategies that are appeared in limits of developed approach have a significant time gain with respect to the traditional strategy. The time gain increases when the size and the complexity of the optimized circuit are increasing. An additional acceleration effect was used to improve the properties of presented optimization process.

Originality/value
– The obtained results show the perspectives of new approach for circuit optimization. A large set of various strategies of circuit optimization serves as a basis for searching the better strategies with a minimum computer time. The gain in processor time for the best strategy reaches till several thousands in comparison with traditional approach.
Finite element modeling and identification of metallic materials step responses
Authors: Pólik Zoltán , Kántor Zoltán 
Published: October 2014

Purpose
– The purpose of this paper is to study the optimization of a pulsed-excitation gradiometric inductive sensing system.

Design/methodology/approach
– The authors applied numerical finite-element modeling for the simulation of the step responses of different target materials to identify the particular contribution of the magnetic permeability and the electric conductivity. Four materials of technical importance (aluminum, copper, constructional steel and stainless steel) and four fictive test materials were modeled for the comparison of different materials possessing a wide range of combinations of material parameters. A microcontroller-based measurement setup was implemented for the qualitative validation of the simulation results. A simple signal processing chain was also applied for the time-domain conversion of the direct step response signals to increase the time scale of the signals to be processed by common mixed-signal components.

Findings
– The step response signals contain relevant information of the target material quality and the sensor-to-target distance. The target materials can be distinguished and the sensor-target distance can be determined by the evaluation of the step response signals with an appropriate algorithm based on the measurement of the time and voltage of an extreme of the time dependent measurement signals. Both direct and time-domain converted signals can be used for material independent proximity sensing.

Originality/value
– In order to design an inductive proximity switch, an evaluation method of the response signals has been proposed by using an analog RLC circuit. With the presented method, a target material invariant inductive proximity switch can be realized.

– Full-wave simulations confirm the capability of the proposed sensor to identify different compounds by refractive index measurement.
Subzone scheme for RBF meshless method in solving multi-medium boundary value problems
Authors: Huaiqing Zhang , Xin Nie , Yu Chen , Zhihong Fu 
Published: October 2014

Purpose
– The purpose of this paper is to solve the interface discontinuities in radial basis function (RBF) method for multi-medium boundary value problems (BVPs). The discontinuity of the solution derivatives is not easily handled with RBF method because of infinitely smoothness.

Design/methodology/approach
– The essence of solving BVP is to construct the continuous potential function surfaces. Hence, from constructing surface aspect, this paper proposed and compared the global and subzone schemes for RBF method. Their implementation schemes and mathematic models can then be derived. Numerical experiments and comparison are carried out for electric and magnetic field calculation.

Findings
– In the numerical experiments, the subzone scheme has shown its significant advantageous, it can approximate not only the potential function but also its derivative on interface boundary with high accuracy. So the physical characteristics of discontinuities on the interface can be revealed clearly. The overall precision is significantly improved.

Originality/value
– This paper proposed an effective subzone scheme for RBF method in multi-medium BVP. It is an improvement for RBF method based on its domain decomposition idea. And it is also a candidate for solving complex BVP.
EGLD system for noise identification in ensemble predictors
Authors: Szupiluk Ryszard , Ząbkowski Tomasz 
Published: October 2014

Purpose– The purpose of this paper is to propose a noise identification method for data without temporal structure, in which application of typical mathematical white or colored noise models is very limited due to observation order requirements. The method is used to identify the destructive elements and to eliminate them what finally brings prediction improvement.Design/methodology/approach– The paper concerns noise detection problem presented in the framework of ensemble methods via blind signals separation. The authors utilize the Extended Generalized Lambda Distribution (EGLD) model to compare the signals with the target.Findings– The authors proposed novel signals similarity measure which is based on the EGLD system. The authors showed that it can be applied for data with or without time structure, as well as for data which are mutually uncorrelated. It turned out that method is effective for noise identification and can be an alternative, in many cases, to correlation approach, particularly for noise identification problems.Originality/value– In this method the improvement of prediction results is associated with elimination of the real physical factors rather than mathematical averaging in terms of arbitrary assumed distributions. In this approach, it does not matter what is the structure of aggregated models, what significantly distinct this approach from such techniques as boosting or bagging, in which the aggregation process applies to the models of similar structure. For this reason the methodology is focussed on physical noises elimination from predictions and it is complementary to the other ensemble approaches.

Design/methodology/approach
– Level-set based topology optimization for two-dimensional optimization problem.

Findings
– It is shown in the numerical examples, where conventional and present methods are applied to shape optimization of ferrite inductor and Interior Permanent Magnetic (IPM)-motor, the present method can find solutions with better performance than those obtained by the conventional method.

Originality/value

Current challenges in information security risk management
Authors: Fenz Stefan , Heurix Johannes , Neubauer Thomas , Pechstein Fabian 
Published: October 2014

Purpose
– The purpose of this paper is to give an overview of current risk management approaches and outline their commonalities and differences, evaluate current risk management approaches regarding their capability of supporting cost-efficient decisions without unnecessary security trade-offs, outline current fundamental problems in risk management based on industrial feedback and academic literature and provide potential solutions and research directions to address the identified problems. Despite decades of research, the information security risk management domain still faces numerous challenges which hinder risk managers to come up with sound risk management results.

Design/methodology/approach
– To identify the challenges in information security risk management, existing approaches are compared against each other, and as a result, an abstracted methodology is derived to align the problem and solution identification to its generic phases. The challenges have been identified based on literature surveys and industry feedback.

Findings
– As common problems at implementing information security risk management approaches, we identified the fields of asset and countermeasure inventory, asset value assignment, risk prediction, the overconfidence effect, knowledge sharing and risk vs. cost trade-offs. The reviewed risk management approaches do not explicitly provide mechanisms to support decision makers in making an appropriate risk versus cost trade-offs, but we identified academic approaches which fulfill this need.

Originality/value
– The paper provides a reference point for professionals and researchers by summing up the current challenges in the field of information security risk management. Therefore, the findings enable researchers to focus their work on the identified real-world challenges and thereby contribute to advance the information security risk management domain in a structured way. Practitioners can use the research results to identify common weaknesses and potential solutions in information security risk management programs.
Teaching information security management: reflections and experiences
Authors: Ahmad Atif , Maynard Sean 
Published: October 2014

Purpose– The purpose of this paper is to describe the development, design, delivery and evaluation of a postgraduate information security subject that focuses on a managerial, rather than the more frequently reported technical perspective. The authors aimed to create an atmosphere of intellectual excitement and discovery so that students felt empowered by new ideas, tools and techniques and realized the potential value of what they were learning in the industry.Design/methodology/approach– The paper develops fundamental principles and arguments that inform the design and development of the teaching curriculum. The curriculum is aimed at security management professionals in general and consultants in particular. The paper explains the teaching method in detail including the specific topics of lectures, representative reading material, assessment tasks and feedback mechanisms. Finally, lessons learned by the authors and their conclusions are presented as a form of reflection.Findings– The instructors recognized four key factors that played a role in the atmosphere of intellectual excitement and motivation. These were new concepts and ideas, an increased level of engagement, opportunities for students to make their own discoveries and knowledge presented in a practical context. Maintaining a high quality of teaching resources, catering for diverse student needs and incorporating learning cycles of assessment in a short period of time were additional challenges.Originality/value– Most “information security” curricula described in research literature take a technology-oriented perspective. This paper presents a much-needed management point of view. The teaching curriculum (including assessment tasks) and experiences will be useful to existing and future teaching and research academics in “information security management”. Those interested in developing their own teaching material will benefit from the discussion on potential topic areas, choice of assessment tasks and selection of recommended reading material.
Market vs. administered Federal Reserve policy rates
Authors: Walker David 
Published: October 2014

Purpose– The purpose of this study is to contrast the discount and the Fed funds rates since 1990 and the variables that influence these rates. On the basis of quarterly data, since 1990, the primary determinants of the two policy rates are: the rate of inflation, the unemployment rate and rates on US Treasury securities, i.Design/methodology/approach– Ordinary least squares models are developed with autocorrelation removed.Findings– 12 per cent level in the Fed funds market rate models. The statistical significance of the coefficient of the spread between long-term and short-term Treasury rates is a projection of a recession one year in the future. The statistical significance of the coefficients for unemployment, one and two quarter the autocorrelation coefficients, adjusted R-square values and Durbin-Watson statistics are similar for the two policy rate models.Research limitations/implications– The major limitation is that monthly data are not available for further tests.Practical implications– The two Fed policy rates respond differently to the impacts of inflation, unemployment and yield curve tilts.Social implications– Expected recessions, reflected by the yield curve are not often anticipated.Originality/value– The approach and results have a different perspective from the work in most studies involving Federal Reserve policy rates.
What threatens public libraries? The viewpoints of library directors in Sweden
Authors: Michnik Katarina 
Published: October 2014

Purpose– This article aims to identify threats perceived by Swedish public library directors as the most prominent.Design/methodology/approach– A web questionnaire was sent to public library directors in all of the Swedish municipalities. The data were analysed using qualitative content analysis.Findings– The findings reveal that the main threat was considered to be the tension between the current activities of the public library and the expectations of the public, or of local decision makers. One reason for the lack of correspondence between activities and expectations is that public library managers regard the expectations on the public library as unrealistic. Another reason is that lack of resources prevent public library staff from meeting many of these expectations. Public libraries are thus prevented by both ideological and practical barriers in fulfilling expectations.Originality/value– A central issue in current public library research concerns how change in Western society affects public libraries. Many of these studies are either theoretical or based on interviews with politicians. Few researchers investigate how public library directors perceive the situation of public libraries today. Therefore, this article identifies perceptions made by public library directors.
