Purpose – Although Generation Y has been extensively examined in the popular and academic literature, there have not been any studies to date that have identified the psychographic profile of this market segment using the VALS scale. The purpose of the research presented in this paper is to provide a segment characterization of Generation Y using the VALS typology and provide insights into the media habits of this population. Design/methodology/approach – The research sample consisted of subjects from Generation Y that were drawn from a population of college students. To determine the VALS types, participants completed the VALS survey in addition to responding to questions related to demographics and media habits. Originality/value – The results contribute to the literature by providing for the first time a segmented characterization of Generation Y consumers. The research provides a detailed perspective of this important market segment and provides marketers with insights on their values, attitudes, and media habits.

Purpose Employee happiness or well-being is an emerging topic in management as well as in psychology. The purpose of this paper is to investigate the effects of perceived organizational support (POS) and psychological capital (PsyCap) on happiness in employees’ work (i.e. work engagement), careers (i.e. career satisfaction), and lives (i.e. subjective well-being (SWB)). Design/methodology/approach Data were collected from 550 employees in a conglomerate in South Korea. For statistical analysis, we conducted confirmatory factor analysis, reliability and correlation analysis, and structural equation modeling analyses. Findings Employees were highly engaged in their work, satisfied with their careers, and felt a greater sense of well-being in their lives when they had higher POS and PsyCap. Work engagement fully mediated the relationship between PsyCap and career satisfaction. POS had an indirect effect on SWB through career satisfaction. With regards to the relationships among the three outcome variables, career satisfaction turned out to fully mediate the relationship between work engagement and SWB. In addition, the direct effect of PsyCap on SWB was also found to be significant. Research limitations/implications This study focused on knowledge workers in South Korean for-profit firms. The participants were mostly male, junior or middle managers. Using a cross-sectional survey method, this empirical study leaves room for speculation about the causality among the variables. As the results of exploratory and confirmatory factor analyses indicate, however, common method variance was found to not be of great concern. Practical implications The mission of human resources (HR) and organization development (OD) professionals in organizations is to improve individual and organizational performance and to enhance employees’ well-being. HR/OD professionals can enhance employees’ happiness not only in their work and careers but also in their lives by improving POS (e.g. growth opportunity, performance management, and compensation system) and developing PsyCap (e.g. staffing, training, and development, etc.). Originality/value This study linked the emerging constructs in positive psychology in general, in HR/OB in particular. To date, no study has empirically investigated the effects of PsyCap and POS on the three workplace happiness constructs: work engagement, career satisfaction, and SWB. This is the first study that found the relationship between POS and PsyCap. Last, while South Koreans are more collectivistic and less satisfied with their lives than the Organisation for Economic Co-operation and Development average, the respondents in this study, working for highly reputable firms, perceived high level of happiness in their work and career, and eventually in their lives. Thus, organizational features had a stronger effect on workplace happiness than national culture.

Purpose The purpose of this paper is to investigate the effect of empowering leadership on employees’ psychological well-being (PWB) and job engagement. This study also examines the mediating role of psychological capital (PsyCap) in these relationships. Design/methodology/approach The study draws on survey data ( n =285) from employees in eight large-sized firms in South Korea. Confirmatory factor analysis was conducted to examine the convergent validity of the construct measures. Structural equation modeling was used to estimate the fit of the hypothesized model to the data. Findings The authors found that empowering leadership influenced job engagement both directly and indirectly through PsyCap. Employees’ PsyCap fully mediated the relationship between empowering leadership and employees’ PWB, while partially mediating the relationship between empowering leadership and job engagement. Originality/value This is the first empirical study to examine the effects of empowering leadership behaviors of leaders on both PWB and PsyCap, which are positive psychological resources of employees. The study has also provided empirical evidence for the importance of PsyCap, which plays a positive role in the ability of employees to manage their overall feelings in achievement situations and in employees’ engagement in the workplace.

To update existing literature and fill the gap in meta-analyses, this meta-analysis quantitatively evaluated the worldwide economic burden (in 2022 US $) of childhood overweight and obesity in comparison with healthy weight. The literature search in eight databases produced 7756 records. After literature screening, 48 articles met the eligibility criteria. The increased annual total medical costs were $237.55 per capita attributable to childhood overweight and obesity. Overweight and obesity caused a per capita increase of $56.52, $14.27, $46.38, and $1975.06 for costs in nonhospital healthcare, outpatient visits, medication, and hospitalization, respectively. Length of hospital stays increased by 0.28 days. Annual direct and indirect costs were projected to be $13.62 billion and $49.02 billion by 2050. Childhood obesity ascribed to much higher increased healthcare costs than overweight. During childhood, the direct medical expenditures were higher for males than for females, but, once reaching adulthood, the expenditures were higher for females. Overall, the lifetime costs attributable to childhood overweight and obesity were higher in males than in females, and childhood overweight and obesity resulted in much higher indirect costs than direct healthcare costs. Given the increased economic burden, additional efforts and resources should be allocated to support sustainable and scalable childhood obesity programs.

UNLABELLED: The angiotensin-converting enzyme (ACE) and the alpha-actinin-3 (ACTN3) genes are two of the most studied "performance genes" and both have been associated with sprint/power phenotypes and elite performance. PURPOSE: To investigate the association between the ACE and the ACTN3 genotypes and sprint athlete status in elite Jamaican and US African American sprinters. METHODS: The ACTN3 R577X and the ACE I/D and A22982G (rs4363) genotype distributions of elite Jamaican (J-A; N = 116) and US sprinters (US-A; N = 114) were compared with controls from the Jamaican (J-C; N = 311) and US African American (US-C; N = 191) populations. Frequency differences between groups were assessed by exact test. RESULTS: For ACTN3, the XX genotype was found to be at very low frequency in both athlete and control cohorts (J-C = 2%, J-A = 3%, US-C = 4%, US-A = 2%). Athletes did not differ from controls in ACTN3 genotype distribution (J, P = 0.87; US, P = 0.58). Similarly, neither US nor Jamaican athletes differed from controls in genotype at ACE I/D (J, P = 0.44; US, P = 0.37). Jamaican athletes did not differ from controls for A22982G genotype (P = 0.28), although US sprinters did (P = 0.029), displaying an excess of heterozygotes relative to controls but no excess of GG homozygotes (US-C = 22%, US-A = 18%). CONCLUSIONS: Given that ACTN3 XX genotype is negatively associated with elite sprint athlete status, the underlying low frequency in these populations eliminates the possibility of replicating this association in Jamaican and US African American sprinters. The finding of no excess in ACE DD or GG genotypes in elite sprint athletes relative to controls suggests that ACE genotype is not a determinant of elite sprint athlete status.

Recently SQL injection attack (SIA) has become a major threat to Web applications. Via carefully crafted user input, attackers can expose or manipulate the back-end database of a Web application. This paper proposes the construction and outlines the design of a static analysis framework (called SAFELI) for identifying SIA vulnerabilities at compile time. SAFELI statically inspects MSIL bytecode of an ASP.NET Web application, using symbolic execution. At each hotspot that submits SQL query, a hybrid constraint solver is used to find out the corresponding user input that could lead to breach of information security. Once completed, SAFELI has the future potential to discover more delicate SQL injection attacks than black-box Web security inspection tools.

In this paper, a new adaptive fuzzy reasoning method using compensatory fuzzy operators is proposed to make a fuzzy logic system more adaptive and more effective. Such a compensatory fuzzy logic system is proved to be a universal approximator. The compensatory neural fuzzy networks built by both control-oriented fuzzy neurons and decision-oriented fuzzy neurons cannot only adaptively adjust fuzzy membership functions but also dynamically optimize the adaptive fuzzy reasoning by using a compensatory learning algorithm. The simulation results of a cart-pole balancing system and nonlinear system modeling have shown that: 1) the compensatory neurofuzzy system can effectively learn commonly used fuzzy IF-THEN rules from either well-defined initial data or ill-defined data; 2) the convergence speed of the compensatory learning algorithm is faster than that of the conventional backpropagation algorithm; and 3) the efficiency of the compensatory learning algorithm can be improved by choosing an appropriate compensatory degree.

In The Balkan Wars 1912-1913, Richard Hall examines the origins, the enactment and the resolution of the Balkan Wars, during which the Ottoman Empire fought a Balkan coalition of Bulgaria, Greece, Montenegro and Serbia. The Balkan Wars of 1912 - 1913 opened an era of conflict in Europe at the beginning of the 20th century, which lasted until 1918, and which established a basis for problems which tormented Europe until the end of the century. Based on archival as well as published diplomatic and military sources, this book provides the first comprehensive perspective on the diplomatic and military aspects of the Balkan Wars. It demonstrates that, because of the diplomatic problems raised and the military strategies and tactics pursued to resolve those problems, The Balkan Wars of 1912-1913 were the first phase of the greater and wider conflict of the First World War.

We present a framework for analyzing interactions among Web services that communicate with asynchronous messages. We model the interactions among the peers participating in a composite Web service as conversations, the global sequences of messages exchanged among the peers. This naturally leads to the following model checking problem: Given an LTL property and a composite Web service, do the conversations generated by the composite Web service satisfy the property? We show that asynchronous messaging leads to state space explosion for bounded message queues and undecidability of the model checking problem for unbounded message queues. We propose a technique called synchronizability analysis to tackle this problem. If a composite Web service is synchronizable, its conversation set remains the same when asynchronous communication is replaced with synchronous communication. We give a set of sufficient conditions that guarantee synchronizability and that can be checked statically. Based on our synchronizability results, we show that a large class of composite Web services with unbounded message queues can be verified completely using a finite state model checker such as SPIN. We also show that synchronizability analysis can be used to check the reliability of top-down conversation specifications and we contrast the conversation model with the Message Sequence Charts. We integrated synchronizability analysis to a tool we developed for analyzing composite Web services.

Purpose The purpose of this paper is to investigate the effect of the perceived authentic leadership of supervisors and employees’ core self-evaluations on their organizational citizenship behavior (OCB) and to examine the role of psychological empowerment as a partial mediator of those relationships. Design/methodology/approach A cross-sectional survey was used to obtain individual perceptions from employees working in one of the biggest companies in Korea. Data from 374 samples was analyzed. Construct validity of each measurement model is examined using confirmatory factor analysis and the hypothesized structural model is tested by structural equation modeling. Findings The authors found that perceived authentic leadership, core self-evaluation, and employees’ psychological empowerment had significant impact on employees’ OCB, accounting for 58 percent of the variance in OCB. In addition, 54 percent of the variance in psychological empowerment was explained by authentic leadership and core self-evaluations, partially mediating the relationship between authentic leadership and OCB and the relationship between core self-evaluations and OCB. Originality/value Positivity is instrumental in driving intrinsic motivation for work and voluntary devotion to colleagues and organizations. This study contributed to the emerging research branch of management and organizational psychology such as positive organization scholarship and positive organizational behavior by exploring the relationship among the relevant constructs. More specifically, the authors found that positive contextual factor (i.e. authentic leadership), positive personality factor (i.e. core self-evaluations), and positive work experience (i.e. psychological empowerment) do have positive influence on employees’ extra-role performance (i.e. OCB).

Theory suggests that eligible voters should be more likely to cast ballots when election margins are close. Empirical evidence, however, is mixed. Operational definitions of key concepts such as turn-out and election closeness are often inconsistent and limited in application to two-party systems. This paper provides a more generalized test of the turnout-competition link in electoral districts. Data are 1993 and 1997 constituency-level election results for the Canadian House of Commons. Canada provides an excellent case for comparison because it has single-member districts, plurality elections, both national and regional parties, and multiparty competition throughout the nation. Several alternative measures for "turnout" and "closeness" are evaluated in the context of multi-party elections. A new index of competitiveness is developed. Multicandidate measures of closeness are related to higher levels of voter participation in Canadian federal elections.

A composite Web service consists of a set of individual services (or peers), which interact with each other via messages. A conversation is a global sequence of messages exchanged among peers participating in a composite Web service. Interestingly, conversation behavior differs significantly for synchronous and asynchronous communication, even if peers' local behaviors remain the same. The authors use synchronizability and realizability analysis techniques to analyze conversations in the presence of asynchronous communication. With these analyses, they can use model checking to automatically verify conversation behavior for bottom-up and top-down Web service specifications.

Real-time route guidance schemes, as one of the critical services in Transportation-based Cyber-Physical Systems, have been introduced to assist travelers in determining optimal routing with low traffic congestion and travel time. To secure the route guidance process, which enables traffic efficiency and safety, in this paper we first investigate security issues of route guidance schemes via modeling and analysis of data integrity attacks on the route guidance process, and then develop corresponding mitigation mechanisms to combat the investigated attack. Via the manipulation of traffic state data measured or generated by compromised vehicles, the data integrity attack can give rise to erroneous predictions of traffic states and induce improper determination of guided routes for vehicles, increasing traffic congestion, and reducing traffic efficiency and safety. We formally model the attack and analyze its impacts on the effectiveness of route guidance schemes. Our results show that the data integrity attack can effectively disrupt route guidance schemes, leading to significant traffic congestion, increased traveling time, and imbalanced use of transportation resources. To mitigate the data integrity attack, we investigate the forged data filtering scheme, in which the forged traffic state data can be filtered out during data delivery in vehicular networks. Extensive performance evaluations are conducted to demonstrate the effectiveness of the proposed forged data filtering scheme in comparing with an exiting scheme.

The OH radical is one of the most important oxidants in the atmosphere due to its high reactivity. The study of hydrogen-bonded complexes of OH with the water molecules is a topic of significant current interest. In this work, we present the development of a new analytical functional form for the interaction potential between the rigid OH radical and H(2)O molecules. To do this we fit a selected functional form to a set of high level ab initio data. Since there is a low-lying excited state for the H(2)O.OH complex, the impact of the excited state on the chemical behavior of the OH radical can be very important. We perform a potential energy surface scan using the CCSD(T)/aug-cc-pVTZ level of electronic structure theory for both excited and ground states. To model the physics of the unpaired electron in the OH radical, we develop a tensor polarizability generalization of the Thole-type all-atom polarizable rigid potential for the OH radical, which effectively describes the interaction of OH with H(2)O for both ground and excited states. The stationary points of (H(2)O)(n)OH clusters were identified as a benchmark of the potential.

SUMMARY The purpose of this study is to test the effects of inappropriate CEO social influence pressure and CFO accounting experience on CFOs' reporting judgments and decisions. Specifically, we use a sample of 69 highly experienced public company CFOs to evaluate the extent that inappropriate compliance or obedience pressure from the CEO to revise financial reporting to meet an earnings target affects CFO revision decisions. The results indicate that compliance pressure (a request) and obedience pressure (an order) from the CEO significantly (and similarly) increase CFO willingness to revise their initial inventory adjustments. Although both types of pressure from CEOs impact CFOs' financial reporting decisions, compliance pressure did not create increased levels of perceived pressure. The results also reveal an inverse relation between CFO accounting experience and revision of the initial estimate. Finally, CFOs who acquiesce to CEO pressure maintain their personal responsibility for the adjustment, contrary to obedience theory, but consistent with the intent of SOX Section 302 certification requirements.

A higher order sliding mode observer is proposed for asymptotic identification of the full state vector and the vector of unknown inputs for MIMO nonlinear causal systems with unstable internal dynamics. The problem is addressed via consistent application of exact higher order sliding mode differentiators in conjunction with the method of stable system center. A numerical example illustrates the performance of the proposed algorithm.

Due to the emergence of positive psychology, literature that has focused on happiness in the workplace has increased over the past two decades. Well-being has become a critical topic for today’s policy makers. Firms have also begun to shed more light on how to enhance employees’ well-being. This study examined how employees’ cognition of work environment related to cognitive engagement and psychological well-being in a South Korean conglomerate. Results of the structural equation modeling showed that perceived work cognitions of 518 employees accounted for 31% of the variance in cognitive engagement. Employees’ work cognition and cognitive engagement explained 50% of the variance in psychological well-being. In addition, cognitive engagement played a role as a partial mediator. Human resource/organization development practitioners and managers might enhance the level of employee engagement and psychological well-being by providing positive organizational support, by redesigning job context, and by enhancing relations with their leaders and coworkers.
