Abstract Purpose of Review Childhood obesity is a global health concern. And a number of studies have indicated that food promotions affect children’s food attitudes, preferences, and food choices for foods high in fat and sugar, which potentially impacts children’s body weight development. This review showcases how children are affected by food promotions, why companies even target children with their promotional efforts, and what makes children so susceptible to promotion of unhealthy food. In addition, this review discusses how regulations, parental styles, and individual media literacy skills can help to contain the potential detrimental effects of food promotions on children’s health. Recent Findings The recent findings indicate that children are affected by food promotions in their preference for unhealthy food and beverages in selection tasks shortly conducted after exposure. Furthermore, results indicate significant effects of food marketing, including enhanced attitudes, preferences, and increased consumption of marketed (predominantly unhealthy) foods connected with a wide range of marketing strategies. Children are particularly vulnerable to promotional efforts and react to it strongly due to their still developing cognitive and social skills as well as their lack in inhibitory control. Summary This review proposes an applied focus that discusses pathways for regulators, parents, and educators. In the light of the discussed results, a large number of studies on food promotion indicate that there is need to react. In all these measures, however, it is of relevance to consider children’s developmental stages to effectively counteract and respond to the potential detrimental effects of food promotions on children’s long-term weight development.

The mobile internet offers 24/7 access to a wide range of social, commercial, and educational opportunities. If the educational opportunities are to be maximized, then a full understanding of user skills, motivations, preferences, and learning profiles is required. The authors propose that this detailed understanding is best informed by adopting a psychological perspective on the mobile learning process. Therefore, this chapter considers the insights that can be derived from viewing mobile learning through a psychological lens: in particular the psychological challenges that mobile learning presents and the importance of considering individual differences in learner skills and behaviors. They also consider the insights that psychology offers in addressing these challenges, especially the importance of media literacy skills, the presentation of learning resources in a way that considers the limited cognitive resources of the learner, and the importance of context and contextualized behavior.

Alcohol misuse on college campuses is an ongoing national public health concern. For many young adults, the transition to college is a high-risk period for the initiation or continuation of problem drinking behaviors. Contrary to assertions of diminishing influence of parents on their children once they enter college, a substantial body of recent research supports the continuing protective influence of parents on the drinking behavior of college students. This chapter reviews the empirical research literature examining parental influences on college student drinking. Recent studies on parental influence on college drinking include parenting styles, parental monitoring, parent–child communication, parental modeling and attitudes toward drinking, and parental relationship quality. Recently developed parent-based interventions designed to reduce problem drinking on college campuses are described and reviewed. Recommendations for parents of college-bound children are provided to help reduce the risk for the development of problem drinking during this important developmental transition.

This study aims to examine the use of non-nutritive (NNSs) and low-calorie sweeteners (LCSs) in pre-packaged foods in Hong Kong and the differences in the number of NNSs/LCSs used between products from different regions. In a cross-sectional audit, the types of NNSs/LCSs used in 19,915 pre-packaged foods in Hong Kong were examined by searching the ingredients list of the included products for keywords related to 20 common NNSs/LCSs and their respective E-numbers. Prevalence of use of NNSs and LCSs, the co-presence of NNSs/LCSs and free sugar ingredients (FSI), and the number of NNSs/LCSs used in the included foods were computed. Pearson’s χ2 test was used to compare the total number of NNSs and/or LCSs used in food items from different regions. Sucralose (E955) was the most commonly used NNS (1.9%), followed by acesulfame K (E950, 1.6%). Sorbitol was the most commonly used LCS (2.9%). Overall, the use of LCSs was less common compared with NNSs (3.7% vs. 4.5%). The use of different types of NNSs varied substantially between food types. Notably, 20.2% of potato crisps and 15.2% of other crisps or extruded snacks contained at least one NNS and/or LCS. Co-presence of FSIs and NNSs/LCSs were most common in confectionery (15.7%) and snack foods (15.5%). Asian prepackaged foods were more likely to contain NNSs/LCSs (10.1%) compared with those from other regions. To conclude, NNSs/LCSs were used in a wide range of non-diet pre-packaged products which could be a public health concern due to their higher consumption frequencies than “diet” products.

Candida auris is an emergent fungal pathogen that causes severe infectious outbreaks globally. The public health concern when dealing with this pathogen is mainly due to reduced susceptibility to current antifungal drugs. A valuable alternative to overcome this problem is to investigate the efficacy of combination therapy. The aim of this study was to determine the in vitro interactions of isavuconazole with echinocandins against C. auris. Interactions were determined using a checkerboard method, and absorbance data were analyzed with different approaches: the fractional inhibitory concentration index (FICI), Greco universal response surface approach, and Bliss interaction model. All models were in accordance and showed that combinations of isavuconazole with echinocandins resulted in an overall synergistic interaction. A wide range of concentrations within the therapeutic range were selected to perform time-kill curves. These confirmed that isavuconazole–echinocandin combinations were more effective than monotherapy regimens. Synergism and fungistatic activity were achieved with combinations that included isavuconazole in low concentrations (≥0.125 mg/L) and ≥1 mg/L of echinocandin. Time-kill curves revealed that once synergy was achieved, combinations of higher drug concentrations did not improve the antifungal activity. This work launches promising results regarding the combination of isavuconazole with echinocandins for the treatment of C. auris infections.

ABSTRACTAntibiotic-resistant bacteria are a significant public health concern and motivate efforts to develop new classes of antibiotics. One such class of antibiotics is the arylomycins, which target type I signal peptidase (SPase), the enzyme responsible for the release of secreted proteins from their N-terminal leader sequences. Despite the essentiality, conservation, and relative accessibility of SPase, the activity of the arylomycins is limited against some bacteria, including the important human pathogenStaphylococcus aureus. To understand the origins of the limited activity againstS. aureus, we characterized the susceptibility of a panel of strains to two arylomycin derivatives, arylomycin A-C16and its more potent analog arylomycin M131. We observed a wide range of susceptibilities to the two arylomycins and found that resistant strains were sensitized by cotreatment with tunicamycin, which inhibits the first step of wall teichoic acid synthesis. To further understand howS. aureusresponds to the arylomycins, we profiled the transcriptional response ofS. aureusNCTC 8325 to growth-inhibitory concentrations of arylomycin M131 and found that it upregulates the cell wall stress stimulon (CWSS) and an operon consisting of a putative transcriptional regulator and three hypothetical proteins. Interestingly, we found that mutations in the putative transcriptional regulator are correlated with resistance, and selection for resistanceex vivodemonstrated that mutations in this gene are sufficient for resistance. The results begin to elucidate howS. aureuscopes with secretion stress and how it evolves resistance to the inhibition of SPase.

The feeding habits of myctophid larvae of Symbolophorus californiensis were examined in the southern transition region of the western North Pacific where the main spawning and nursery grounds of S. californiensis are formed. This species is a key component of the pelagic ecosystems of this region, and their larvae attain one of the largest sizes among myctophids. To analyse gut contents larvae, including most life history stages after yolk-sac absorption (3.7 to 22.2 mm body length (BL)), were collected in the upper 100 m layer in 1997 and 1998. Feeding incidence was higher during the day than at night (53.1–92.3% versus 0–5.6%), and daytime feeding incidence increased gradually with larval growth. Larvae fed mainly on copepods of various developmental stages. Larvae of S. californiensis showed an ontogenetic change in their diet: larvae ≤7.9 mm BL (i.e. preflexion stage) fed mainly on copepod eggs and nauplii, while the larvae ≥8 mm BL consumed mainly calanoid copepodites such as Pseudocalanus and Paracalanus spp. In the largest size-class (16–22.2 mm BL), the furcilia stage of euphausiids was also an important prey item. There was an increase in the average prey size with growth in larvae ≤11.9 mm BL, while the number of prey eaten positively correlated with growth in larvae ≥12 mm BL. The trophic niche breadth also increased with larval growth, which would ensure a wide range of available food resources for the larger size-class larvae.

Purpose This paper aims to demonstrate how teaching the discourse of critique, an integral part of the video production process, can be used to eliminate barriers for young people in gaining new media literacy skills helping more young people become producers rather than consumers of digital media. Design/methodology/approach This paper describes an instrumental qualitative case study (Stake, 2000) in two elective high school video production classrooms in the Midwestern region of the USA. The author conducted observations, video and audio recorded critique sessions, conducted semi-structured interviews and collected artifacts throughout production including storyboards, brainstorms and rough and final cuts of videos. Findings Throughout critique, young video producers used argumentation strategies to cocreate meaning, multiple methods of inquiry and questioning, critically evaluated feedback and synthesized their ideas and those of their peers to achieve their intended artistic vision. Young video producers used feedback in the following ways: incorporated feedback directly into their work, rejected and ignored feedback, or incorporated some element of the feedback in a way not originally intended. Originality/value This paper demonstrates how teaching the discourse of critique can be used to eliminate barriers for young people in gaining new media literacy skills. Educators can teach argumentation and inquiry strategies through using thinking guides that encourage active processing and through engaging near peer mentors. Classroom educators can integrate the arts-based practice of the pitch critique session to maximize the impact of peer-to-peer learning.

The purpose of this study is to determine the demographic profiles of the respondents which are the teachers in Mindanao State University–Sulu according to gender and college, to identify the issues encountered by the MSU-Sulu Teacher towards modular distance learning approach, to distinguish the concerns of the MSU-Sulu Teacher towards modular distance learning approach, to investigate the teaching preparations on the adaptation of modular distance learning approach, and to identify the significant difference of issues and concern of the MSU-Sulu Teacher towards modular distance learning approach when they are grouped according gender and college. Frequency and percentage distribution, weighted arithmetic mean and independent t-test and chi-square are the statistical tools used to answer the entire research question. The data gathered was computed using SPSS analyzed and interpreted with the aide of the statistician. Descriptive survey method was used as the research method. This study utilizes 40 teachers from different colleges/department. Convenience sampling was used to It is the recommended number of which it is the 30% from the total population of all the faculty of Mindanao State University-Sulu.; questionnaire is used by the researcher as a research instrument of the study. The findings of the study were: 1) There is no significant difference of issues and concern of the MSU-Sulu teacher towards modular distance learning approach when grouped according gender but in contrary; and 2) There is significant difference on the issues and concern among MSU-Sulu teacher towards modular distance learning approach when grouped according colleges. The issues encountered towards modular distance learning approach were communication failure like that of instructions or confusion of students on the modules, limited teacher guidance, student’s in discourteous approach to teachers, complaints on not understanding the module, and all of which results to misbehavior on students and failure to pass worksheet on time. In addition, the concerns of the MSU-Sulu teacher towards modular distance learning approach were; first, hidden expenses on modules; second, teacher’s lack of media literacy; third, poor internet connection which intercepts communication between teacher and students; fourth, time constraint among teachers due to overload paperwork; fifth, equipment problem and complexity of the discussion as well as measurement of student’s performance; sixth,  managing student’s responses from time to time; seventh, teacher’s unavailability  and lastly, difficulties of studying among slow learners. Moreover, on teaching preparations on the adaptation of modular distance learning approach, the issues were cater and set time for student’s inquiries and be flexible to allow extension in terms of passing worksheets as well as allow parents, relative or even friends to pass worksheets in their behalf to lessen transportation expenses. Teachers must appreciate/ recognize his/her students to boost their confidence and avoid favouritism while being considerate to students who are attention seeker or may have ADHD. Correspondingly, the concerns were. Teachers must encourage handwritten answers to lessen plagiarism, on the absence of teacher, the parents and elders must guide the students in their learning at home. Teacher and parent’s guidance must go hand and hand in today’s learning. Teachers must likewise be flexible in finding solutions on printing shortage. And lastly, alternative teaching strategies like modular learning should be hone to aid lack of media literacy of both teacher and students In view of the findings and analysis, the following are recommended: Teachers must be flexible with the present kind of teaching strategy at all cost and at all aspects, Set guidelines as to establish proper communication among students and teachers, learning materials must be affordable as well as easy to understand content, teachers must develop their media literacy skills and encourage teachers to be available to their students on allotted time and cater all their inquiries with patience at all times. Furthermore, the following are the recommended research agenda: Teacher’s training on media literacy and module development programs to allow teamwork in the making process.

The palps of all stages of Ixodes trianguliceps are provided with a ventral plate below the basal article; formerly this plate was thought to be the first palpal article. This article in the larva and nymph is produced forward into a spur, but in the female tick this spur is incorporated into the basis capituli as the sella. The hypostomes of I. trianguliceps and I. canisuga are redescribed to clear up existing inaccuracies.Ticks in which the rostrum does not extend beyond the apex of the first palpal article are found on birds, and this probably represents a primitive condition. Those with palpal spurs, which may or may not be fused with the basis capituli, are found on birds (not in Britain) or on mammals of the mouse size group, and those where the rostrum is produced beyond the first palpal article occur on a wide range of large and small animals. The longer and more heavily toothed digits of ticks appear to be associated with a wide host range and vice versa. The structure of the digit may also influence the choice of attachment sites by ticks on their hosts because the microstructure of the skin varies in different parts.Variations in size and form of the scuta of some British ticks are described, and the mean growth rate is ascertained from this data. The information shows that the material of I. ricinus and I. hexagonus is homogeneous, and that specific differences occur in size, shape, the position and type of dermal ducts and in the relation between scutal and alloscutal bristles.The morphology of Gené's organ in I. hexagonus is described. It consists of a basal sac-like portion surmounted by four horns and lined with a cuticle beneath an epithelium. The gland is a proliferation of the epithelium and located near the bifurcation of the base into the horns. A watery refractile fluid, secreted by the gland, accumulates between the epidermis and the cuticle in the horn-like extensions. Proximally the thick endocuticle and epidermis lie close together, and two cuticularized rods penetrate the endocuticle for about half-way along the stalk. The rods arise from the postero-dorsal margin of the basis capituli. Muscles, arising from the free ends of the rods, pass back to near the hind-margin of the scutum; they retract the basis capituli after egg laying and indirectly assist in the retraction of Gené's organ. A suggested mechanism for everting Gené's organ in I. hexagonus is outlined.During feeding the opisthosomatic cuticle of all developmental stages of the tick is much stretched. In the larva, where the cuticle is thin, this is effected by the flattening of the epicuticular pleats, but nymphs and females have, in addition, two longitudinal folds alongside the body which stretch to a far greater extent than do the epicuticular pleats. Similar folds are present between the hard ventral plates and the scutum and between the epimeral and median plates in the male. Coupled with the large size of the male digit, this suggests that morphologically, at least, males can imbibe blood.The growth of the leg segments of I. hexagonus is not constant from stage to stage, and as a result the shortest ‘leg-length’ of the female exceeds the longest ‘leg-length’ of the male.
