Objective: Despite extensive debate about the curricular mission of community colleges, prior research has not sufficiently analyzed differences in the kinds of degrees (i.e., the field of study and award level) community colleges produce. Therefore, we explore both the fields of study and the levels at which public community colleges grant degrees and analyze how this has changed over time. Method: Multilevel latent class analysis is used here to estimate latent degree-granting profiles, and colleges are allocated into the profiles based on their observed degree-granting behaviors from 1987 to 2012. Results: The analysis shows that public community colleges can be allocated into five distinct degree-granting profiles over the period of study. A small minority of colleges have and continue to engage almost exclusively in a vocational mission. The two degree profiles that increased in prominence over time suggest an overall shift toward the simultaneous pursuit of transfer and vocational missions. However, a majority of colleges (68%) exhibited stable degree-granting behaviors between 1987 and 2012, indicating a relatively high level of stability in degree-granting patterns across community colleges during this period. Contribution: These patterns highlight variation across colleges and both stability and change within institutions over time. This suggests that public community colleges are simultaneously situated in strong institutional and technical environments and, thus, are subject to constraints and incentives that shape not only their stated policies but also their actual degree-granting behaviors.

Due to the heterogeneity of homicide, certain subtypes of homicide might have remained stable or even increased over time in the overall context of decline. Adding to the research attempting to identify a standardized classification system of homicide, this study used a novel, sophisticated statistical approach (multilevel latent class analysis [MLCA]) and an inductive theoretical stance to identify subtypes of homicide in Scotland and to examine how these types have changed over time. Using variables relating to the victim, offender, and the incident of homicide, four between-level types with three within-level classes of offenders in each type were identified. The findings showed that while all homicide types demonstrated an absolute decrease, domestic homicides had demonstrated a relative increase over time. Implications for policy, theory, and practice are discussed.

Previous studies have shown that bullying and victimization can be experienced simultaneously by an individual and can change over time. Understanding the joint longitudinal development of the two is of great significance. We conducted a 4-year longitudinal study to examine the joint developmental trajectories of bullying and victimization, gender and grade differences in trajectory group membership, and changes in specific forms of bullying and victimization (verbal, relational, and physical bullying /victimization) in each trajectory group. A total of 775 children from China participated in our study. The average age of participants at the first wave was 10.90 years ( SD = 1.12), and boys accounted for 69.5% of the sample. Based on mean scores, four distinct joint developmental trajectories of bullying and victimization were found: the involvement group (both bullying and victimization increased from low to high over time, accounting for 7.6% of the total), the desisted group (both bullying and victimization decreased from high to low over time, 6.1%), the victimization group (victimization remained at a high level, whereas bullying remained at a low level for 3 years, 13.2%), and the noninvolved group (bullying and victimization remained at a stable low level, 73.1%). Boys were more likely than girls to belong to the involvement group, desisted group, and victimization group, whereas girls were more likely than boys to belong to the noninvolved group. There was no significant grade difference in the trajectory group. All forms of bullying/victimization were consistent with the overall trend and showed similar levels. These results have important implications for the prevention of and interventions for school bullying.

Introduction: Blood pressure trajectories have been associated with cardiovascular disease (CVD) in observational studies. It is unclear whether these associations are independent of average blood pressure over time. Methods: We used data from SPRINT to identify systolic blood pressure (SBP) trajectories among a cohort of 8901 participants by incorporating SBP measures during the first 12 months of the trial post randomization. Trajectories were identified using latent class based modeling. Study outcomes included incident CVD, defined as myocardial infarction, acute coronary syndrome not resulting in myocardial infarction, stroke, acute decompensated heart failure, or death attributable to CVD, and all-cause mortality. Cox proportional hazards models were used to evaluate associations between SBP trajectories and our outcomes of interest. Results: Four distinct SBP trajectories were identified: ‘low decline’ (40%), ‘high decline’ (6%), ‘low stable’ (48%), and ‘high stable’ (5%) (Figure 1). Relative to the low decline group, the low stable group was associated with a 29% increased risk of CVD (HR: 1.29, 95%CI: 1.06-1.57) and the high stable group was associated with a 76% increased risk of all-cause mortality (HR: 1.76, 95%CI: 1.15-2.68) after baseline multivariable adjustment. Relative to the low stable group, the high stable group was associated with a 54% increased risk of all-cause mortality (HR: 1.54, 95%CI: 1.05-2.28). When adjusting for average blood pressure across the 12 month time period, there were no significant differences in outcomes. Conclusion: We identified 4 SBP trajectories using data from SPRINT and found differences in the risk of CVD and all-cause mortality after baseline adjustment. However, there were no differences in the risk of these outcomes after adjusting for average blood pressure over time. These results suggest that the pattern of blood pressure control may not be relevant as long as the target blood pressure is achieved.

BackgroundClinical and aetiological heterogeneity have impeded our understanding of depression.AimsTo evaluate differences in psychiatric and somatic course between people with depression subtypes that differed clinically (severity) and aetiologically (melancholic v. atypical).MethodData from baseline, 2-, 4- and 6-year follow-up of The Netherlands Study of Depression and Anxiety were used, and included 600 controls and 648 people with major depressive disorder (subtypes: severe melancholic n = 308; severe atypical n = 167; moderate n = 173, established using latent class analysis).ResultsThose with the moderate subtype had a significantly better psychiatric clinical course than the severe melancholic and atypical subtype groups. Suicidal thoughts and anxiety persisted longer in those with the melancholic subtype. The atypical subtype group continued to have the highest body mass index and highest prevalence of metabolic syndrome during follow-up, although differences between groups became less pronounced over time.ConclusionsCourse trajectories of depressive subtypes mostly ran parallel to each other, with baseline severity being the most important differentiator in course between groups.

The potential of the most recent membrane technology is still unaccounted for in many respects. Combining fermentation with up-to-date membrane technology building a membrane bioreactor allows the adjustment of the cell count on a high level, increasing yield per volume and time. Applied to beer manufacturing, main fermentation times of less than 20 h seem possible, avoiding the disadvantages of already known accelerated fermentation processes operated on a continuous basis. Although module design was adapted and backwash procedure altered to gas-jet, maintaining a sufficient membrane flux over time still poses a major problem. Nevertheless, preliminary results in respect of beer quality look promising.

Although tinnitus represents a major global burden, no causal therapy has yet been established. Ongoing controversies about the neuronal pathophysiology of tinnitus hamper efforts in developing advanced therapies. Hypothesizing that the unnoticed co-occurrence of hyperacusis and differences in the duration of tinnitus may possibly differentially influence the neural correlate of tinnitus, we analyzed 33 tinnitus patients without (T-group) and 20 tinnitus patients with hyperacusis (TH-group). We found crucial differences between the T-group and the TH-group in the increase of annoyance, complaints, tinnitus loudness, and central neural gain as a function of tinnitus duration. Hearing thresholds did not differ between T-group and TH-group. In the TH-group, the tinnitus complaints (total tinnitus score) were significantly greater from early on and the tinnitus intensity distinctly increased over time from ca. 12 to 17 dB when tinnitus persisted more than 5 years, while annoyance responses to normal sound remained nearly constant. In contrast, in the T-group tinnitus complaints remained constant, although the tinnitus intensity declined over time from ca. 27 down to 15 dB beyond 5 years of tinnitus persistence. This was explained through a gradually increased annoyance to normal sound over time, shown by a hyperacusis questionnaire. Parallel a shift from a mainly unilateral (only 17% bilateral) to a completely bilateral (100%) tinnitus percept occurred in the T-group, while bilateral tinnitus dominated in the TH-group from the start (75%). Over time in the T-group, ABR wave V amplitudes (and V/I ratios) remained reduced and delayed. By contrast, in the TH-group especially the ABR wave III and V (and III/I ratio) continued to be enhanced and shortened in response to high-level sound stimuli. Interestingly, in line with signs of an increased co-occurrence of hyperacusis in the T-group over time, ABR wave III also slightly increased in the T-group. The findings disclose an undiagnosed co-occurrence of hyperacusis in tinnitus patients as a main cause of distress and the cause of complaints about tinnitus over time. To achieve urgently needed and personalized therapies, possibly using the objective tools offered here, a systematic sub-classification of tinnitus and the co-occurrence of hyperacusis is recommended.

Temporal Event Sequences

Temporal event sequence alignment has been used in many domains to visualize nuanced changes and interactions over time. Existing approaches align one or two sentinel events. Overview tasks require examining all alignments of interest using interaction and time or juxtaposition of many visualizations. Furthermore, any event attribute overviews are not closely tied to sequence visualizations. We present SEQUENCE BRAIDING, a novel overview visualization for temporal event sequences and attributes using a layered directed acyclic network.SEQUENCE BRAIDING visually aligns many temporal events and attribute groups simultaneously and supports arbitrary ordering, absence, and duplication of events. In a controlled experiment we compare SEQUENCE BRAIDING and IDMVis on user task completion time, correctness, error, and confidence. Our results provide good evidence that users of SEQUENCE BRAIDING can understand high-level patterns and trends faster and with similar error.

In the present article we apply a growth mixture model using Mplus via STREAMS to delineate the mechanism underlying travel-mode choice. Three waves of an experimental field study conducted in Frankfurt Main, Germany, are applied for the statistical analysis. Five major questions are addressed: (1) whether the choice of public transport rather than the car changes over time; (2) whether a soft policy intervention to change travel mode choice has any effect on the travel-mode chosen; (3) whether one can identify different groups of people regarding the importance allocated to monetary and time considerations for the decision of which travel mode to use; (4) whether the different subgroups of people have different initial states and rates of change in their travel-model choices; (5) whether sociodemographic variables have an additional effect on the latent class variables and on the changes in travel-mode choice over time. We also found that choice of public transportation in our study is stable over time. Moreover, the intervention has an effect only on one of the classes. We identify four classes of individuals. One class allocates a low importance to both monetary and time considerations, the second allocates high importance to money and low importance to time, the third allocates high importance to both, and the fourth allocates a low importance to money and a high importance to time. We found no difference in the patterns of travel-mode changes over time in the four classes. We also found some additional effects of sociodemographic characteristics on the latent class variables and on behavior in the different classes. The model specification and the empirical findings are discussed in light of the theory of the allocation of time of Gary Becker.

Purpose The purpose of this paper is to examine how corruption has changed over time in South Korea and to explore how the corruption control and prevention efforts of the Korean government have been successful and failed. Design/methodology/approach This paper draws on institutional theory to formulate a qualitative analysis to assess the effectiveness of anti-corruption policies and measures, and to identify the strengths and weaknesses of anti-corruption reform efforts in South Korea. Findings This paper argues that while the Korean government has been quite successful in building anti-corruption institutions to control low-level petty corruption, it has failed to institutionalize anti-corruption institutions to curb high-level grand corruption. Originality/value While many studies have attempted to identify the successful factors of fighting corruption, this paper draws a theoretical distinction between institution-building vs institutionalization to examine the success and failure of corruption control and prevention efforts in South Korea.

This article develops the concept of temporal affordances as a framework for understanding and evaluating the relationship between news technologies and journalistic storytelling practices. Accordingly, temporal affordances are defined as the potential ways in which the time-related possibilities and constraints associated with the material conditions and technological aspects of news production are manifested in the temporal characteristics of news narratives. After identifying six such affordances – immediacy, liveness, preparation time, transience, fixation in time, and extended retrievability – we examine manifestations of temporal affordances in different journalistic cultures over time, based on a content analysis of Israeli and US news narratives in different technological eras (from 1950 to 2013). The findings point to a consistent pattern of inter-media differences, in accordance with the distinct affordances of print and online news, alongside cross-cultural and cross-organizational variations in the use of these affordances. In addition, we detect complex patterns of stability and change in the use of temporal affordances in print media over time. Implications and directions for future research are discussed.
